Percy Jackson and the Olympians main characters

Percy Jackson

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

Perseus "Percy" Jackson is a young demigod, the son of the mortal Sally Jackson and the Greek god Poseidon. He is the main protagonist and first-person narrator in the Percy Jackson & the Olympians series and one of the 7 main characters in the follow-up Heroes of Olympus series. He appears directly in every book of the two series except The Lost Hero, though he is mentioned in all. Like other half-human demigods, he is expected to act as the Olympian gods' agent in the mortal world, taking action where ancient laws forbid direct godly intervention, usually in the form of quests. In "The Lightning Thief" Poseidon says that Percy was the result of his "wrongdoing ", which makes Percy a bit uncomfortable. He is twelve years old in The Lightning Thief, and 16 years old in The Last Olympian. The Blood of Olympus (the last book of the franchise) ends with Percy and his girlfriend Annabeth Chase planning to finish senior year in New York before heading to the college in New Rome.[1]

The powers he inherited from his father include controlling water, making hurricanes, breathing underwater, and talking to horses and sea creatures. He is also a notably good swordsman. Percy Jackson's fatal flaw is loyalty, which he does not at first see as a danger.[2] Throughout the series, Percy fights by using a ballpoint pen named Anaklusmos (Ancient Greek for "riptide") that changes into a "celestial bronze" sword when it is uncapped (in the books) or clicked (in the movies). He is described as having a "Mediterranean" complexion, with black hair and his father's sea green eyes.[3]

In the films, he is portrayed by Logan Lerman.

Annabeth Chase

Annabeth Chase is one of Percy Jackson's closest friends, first appearing as a twelve–year-old who helps nurse him back to health after he fights the Minotaur. She is the daughter of the goddess Athena and mortal history professor Frederick Chase, from whom she has an extensive paternal family, including two half-brothers named Matthew and Bobby Chase, an uncle named Randolph, an aunt, and three cousins, one of whom, Magnus, stars in his own series, Magnus Chase and the Gods of Asgard. Annabeth has blond hair, stormy gray eyes, and tan skin . As a daughter of Athena, she is naturally intelligent, with a particular gift for strategy. She repeatedly expresses a desire to become an architect, and, at the end of The Last Olympian, she is assigned to redesign the damaged city on Mount Olympus. Her fatal flaw is hubris, and her greatest desire is to "rebuild the world from scratch". She is also described by her teacher Chiron as "territorial about her friends", which is manifested in several moments of jealousy and distrust towards other characters; in particular, toward friends of Percy. In The Lightning Thief, it is revealed that she is terrified of spiders.

Her main weapon is a short celestial bronze knife given to her by Luke Castellan, her old friend (whom she loses twice, once as he takes on the Titan Kronos' spirit, and again in The Last Olympian, as he dies). However, it breaks in the House of Hades, so now she uses a sword given to her by the giant Damasen. Annabeth also uses a Yankees baseball cap (given to her by her mother for her 12th birthday) that makes its wearer invisible, and a bronze shield (made by Charles Beckendorf) that shows any location under the sun and can be disguised as a platter. At the end of The Battle of the Labyrinth, Daedalus gives Annabeth his computer of projects that leads her to many great discoveries.[4]

Annabeth runs away from her father and stepfamily at age seven and encounters two other demigods, Luke Castellan, son of Hermes, and Thalia Grace, daughter of Zeus. They live as runaways until they are found by Grover Underwood, a satyr who has been ordered to escort Thalia back to camp. Annabeth and Percy Jackson grow close during several quests together—although she remains attached to Luke and convinced of his goodness, causing some jealousy and conflict with Percy.[5] Her attempts to bring Luke back into the fold are an important theme in the books.

Annabeth is crucial in the series. Percy undertakes a quest in The Titan's Curse to save her from Atlas's curse. Being a lifelong fan of Daedalus, Annabeth is selected the leader for the party in search of Daedalus in The Battle of the Labyrinth. The realization that he is doing more harm than good to Annabeth is what causes Luke to sacrifice himself to defeat Kronos in The Last Olympian, thereby ending the Second Titanomachy, after which Annabeth begins dating Percy. In The Son of Neptune, Percy loses virtually all of his memories except for Annabeth's name and face, thus anchoring his resolve that he does not belong in Camp Jupiter. During The Mark of Athena, Annabeth is given the task of restoring the long-lost Athena Parthenos to the Greeks by following the Mark of Athena, an ancient coin with the Athenian motto on it and special powers.[6] She also spends some time in Tartarus with Percy and Bob the Titan during the House of Hades. At the end of the series, she and Percy plan to finish high school in New York and then attend college in New Rome.

Annabeth's appearances in the crossover shorts with The Kane Chronicles and the Magnus Chase and the Gods of Asgard series make her the only character who has appeared in all three of the Greek-Roman, Egyptian, and Norse mythology series. She acts as one of the main characters in the former series, while in the latter, she serves as a supporting character who is reunited with her estranged cousin, Magnus, who is secretly a son of a Norse god, Frey.

In the film adaptations, she is portrayed by Alexandra Daddario.

Grover Underwood

Grover Underwood is a satyr who is Percy's best friend. Grover is described as having curly brown hair, brown eyes, pimply skin, a wispy beard, and brown goat-legs (which he disguises with fake feet when necessary). His horns grow larger as the series progresses, and he must take increasingly careful measures to hide them while posing as human. He is a vegetarian but also eats tin cans, napkins, furniture, silverware and enchiladas. Chronologically, Grover is in his thirties, but because a satyr's lifespan is twice that of a human, he is still considered a young teenager in his community. Grover is a very sensitive person, concerned particularly for the safety of nature and nature spirits—and like all satyrs, he can sense the emotions of others around him and smell monsters and demigods. As the series progresses, his concern for his friends and pursuit of his goals lead him to take on leadership roles and become more sure of himself. Unlike his demigod friends, Grover is not an orthodox fighter. Instead, he uses a magical flute, which he uses to manipulate nature into his control; at his peak, Grover is able to create physical things, such as a cage, out of nothingness. In The Battle of the Labyrinth, Grover begins a relationship with the wood nymph Juniper.

He is first seen in The Lightning Thief, where he is disguised as a human student at Percy's school, serving as his "protector". Grover later reveals that if he completes a protector mission, he will receive his "searcher's license", and leave to look for the missing god Pan, his life's ambition.[3] When Polyphemus captures him in The Sea of Monsters, he forms a psychic bond with Percy, called an empathy link, allowing them a limited degree of telepathic communication across great distances. He uses this ability to guide Percy to his rescue.[7] He joins Percy's quest to find Artemis in The Titan's Curse. He eventually finds Pan in The Battle of the Labyrinth, and receives the wild god's spirit, though the Council of Elders do not believe his having witnessed Pan's death. At the end of The Last Olympian, he is named a Lord of the Wild and given a seat on the satyrs' ruling council.

In the film adaptations, Grover is portrayed by Brandon T. Jackson.

Luke Castellan

Luke Castellan is a 19-year-old demigod (in The Lightning Thief), the son of Hermes and May Castellan. Introduced as the friendly head counselor of the Hermes cabin, he is soon revealed to be a servant of Kronos. Luke is resentful of his father, who adhered to the gods' policy of non-interference, even though Luke's single mother is mentally unbalanced and often fails to be a good caretaker for her son. Luke runs away from home young, meeting up with Annabeth Chase and Thalia Grace and eventually arriving at Camp Half Blood. After the loss of Thalia, a failed quest, and continued silence from his father; his ongoing resentment turns into a strong hatred of not only Hermes, but all the gods.

Luke is described as strikingly handsome with sandy hair, blue eyes (gold when possessed by Kronos), and a long scar on his cheek given to him by Ladon while trying to steal a golden apple from the Garden of the Hesperides. Though described by those who knew him before he joined up with Kronos as an all-around nice guy, his personality takes a turn towards moodiness and violence after he switches "sides." He remains attached to and protective of some of his friends, in particular Annabeth and Thalia.

Luke is first and foremost an excellent swordsman, arguably the best swordsman in Camp Half Blood. He even receives a sword named "Backbiter" from his master Kronos at the end of The Lightning Thief. This sword, which is later reforged as Kronos's scythe, has the ability to harm both mortals and monsters. From the demigod Halcyon Green, he receives a celestial bronze knife and diary; Luke later gives this knife to Annabeth with a promise to always remain her family and entrusts the diary to Chiron. From his father he receives a pair of magic flying shoes, which he later curses and gives to Percy Jackson. He has also inherited an ability to open locks with his mind, along with a cunning nature, from his father. Just before giving himself over completely to host the spirit of Kronos, Luke bathes in the river Styx and obtains the invincibility of Achilles.

Though Luke originally serves Kronos willingly, the horrors he witnesses during the Battle of Manhattan convince him to fight against his former master, eventually committing suicide to stop the Titan. By doing this, Luke proves himself to be the "hero" of the Great Prophecy. As he dies, Luke reiterates what Ethan Nakamura tells Percy earlier: that unclaimed children and unrecognized gods deserve more respect than they have been given. Luke also says that he will try for rebirth rather than stay in the Underworld after his death.

In the films where he is the main antagonist, he is portrayed by Jake Abel. In this version, as well as being a master swordsman, Luke is also incredibly skilled in unarmed combat, easily overpowering Percy Jackson when the latter was carrying the sword. Also, he is inexplicably able to ride on the waves that Percy creates, possibly due to the fact that Percy solidifies the water he rides on.

Thalia Grace

Thalia Grace is the daughter of Zeus and Beryl Grace, a TV starlet the god met in the 1980s. In The Lost Hero she is revealed to be the older sister of Jason Grace.[8] Due to her mother's abusive nature, Thalia has considered leaving home since she was little, but stays to protect Jason from her mother's antics. However, when Jason is apparently killed during a visit to Sonoma (in actuality, he is merely presented to Hera), Thalia finally runs away at age 9 and stays with Luke Castellan and Annabeth Chase until they meet Grover Underwood when she is 12. When the party reaches Camp Half-Blood, Thalia gives her life to hold off pursuing monsters on top of what would later be called Half-Blood Hill. To save Thalia's life, her father transforms her into a pine tree. Her spirit then provides a magical barrier that protects the camp until six years later when it is purged from the pine tree by the golden fleece.

Thalia is pursued so fiercely by monsters because she is a violation of the "Big Three Oath", which was a promise between the three eldest male Olympians to have no more children, for fear of "The Great Prophecy" coming true. At the end of The Titan's Curse, she joins the Hunters of Artemis, a band of immortal female archers in service to the goddess Artemis. This freezes her age the night before her sixteenth birthday, taking her out of the running for the prophecy.

Thalia has electric-blue eyes and spiky black hair, and wears dark makeup and punk style clothing. Annabeth remarks that Thalia's personality and character traits—such as her bravery and loyalty—are very similar to Percy's, and the centaur Chiron later says much the same. She also shares some traits with her father Zeus, including sometimes over-the-top pride, confidence, and reactions to betrayal or contradiction. She is also an incredibly skilled warrior, willing to attack even Luke Castellan, recognized as the best swordsman Camp Half-Blood has ever known. Thalia's weapons of choice are at first a shield named Aegis disguised as a silver charm bracelet (this gift from her father causes paralyzing fear in those who see it because the head of Medusa is pictured on the shield), and a spear disguised as a Mace canister. After The Titan's Curse, she uses a bow and hunting knives, but still uses Aegis. Her main "power" is the ability to summon lightning and generate electric shocks. In The Titan's Curse,it is revealed that she has a fear of heights.

In the film Percy Jackson: Sea of Monsters, she is portrayed by Canadian actress Paloma Kwiatkowski.

Tyson

Tyson is Percy's younger brother. In The Sea of Monsters, he is introduced as Percy's bullied, childish friend. When Percy is forced to take him to Camp Half Blood, it is revealed that he is a baby Cyclops, and a son of Poseidon—making him Percy's half-brother. Percy is at first resentful of him as a brother, while Annabeth is openly hostile towards him, but both accept him after they get to know him better during a quest to the Sea of Monsters.

Tyson is described as tall with unkempt teeth and fingernails, and brown hair and eye. He is mentally about 8 years old, but fairly intelligent and extremely compassionate. As a son of Poseidon, Tyson has some limited powers over sea creatures and water. As a Cyclops, he is immune to fire and super-strong; has an uncanny ability to mimic voices; has enhanced senses; and can understand the "old tongue" (the language spoken by Gaea to her first children). Tyson also becomes an excellent smith with help from Beckendorf. In The Last Olympian, he proves himself also to be a capable fighter and is named a general of Poseidon's armies. He leads his fellow Cyclops' into the fight with battle cry of "Peanut Butter!"

Tyson is close with several characters and magical creatures in the series. The first is the hippocampus Rainbow. He also befriends the hellhound Mrs. O'Leary. In The Battle of the Labyrinth, Tyson is revealed to be afraid of satyrs, including Percy's friend Grover; he manages to conquer this fear after a quest with Grover, and befriends the satyr. In the Heroes of Olympus series, Tyson also begins a romantic relationship with the harpy Ella.

In the Percy Jackson: Sea of Monsters movie, he is portrayed by Douglas Smith.

Nico di Angelo

Nico di Angelo is first seen in The Titan's Curse, when several other characters come to his boarding school in Maine to bring him and his sister, Bianca di Angelo, to camp. At the end of The Titan's Curse, it is revealed that Nico is a son of Hades. Though he appears to be ten years old and therefore a violation of the "Big Three Oath", it is later discovered that he and his sister were born in the 1940s; and, after having their memories wiped, stayed in the Lotus Hotel and Casino until the present day.[9] He undertakes a quest to discover his history, and learns that his mother was Maria di Angelo, the daughter of an Italian diplomat.

Nico is initially depicted as cheerful and childish, and described as olive skined and dark-haired. He enjoys playing Mythomagic (a Greek-mythology-themed card game similar to Magic: The Gathering) and can quote the fictional statistics of gods and monsters from memory. After Nico learns of Bianca's death in The Titan's Curse, he becomes moody and secretive. From this point on, he is usually described as pale and shaggy-haired, always wearing dark clothing. Nico, despite being an extremely powerful demigod, is depicted also as extremely lonely due to his frightening powers and family reputation, much like Hades himself. He makes many other characters uncomfortable, in part due to his powers over the dead and his unnerving weapon of choice: a sword made of iron cooled in the Styx called Stygian Iron capable of absorbing monsters' essences, rather than simply banishing them to Tartarus.

Nico initially blames Percy for the death of his sister Bianca. In The Battle of the Labyrinth, Nico contacts Bianca's ghost and, after learning that holding grudges is a fatal flaw for Hades's children, he lets go of his hatred. From this point on until meeting Cupid in The House of Hades, Nico struggles with an attraction to Percy, developed when Percy first protected him from Dr. Thorn in 'The Titan's Curse', which he considers embarrassing and tries to hide. At the end of The Blood of Olympus, it is implied that he begins a relationship with Will Solace, son of Apollo.

Nico is important to the plots of both Percy Jackson & the Olympians and The Heroes of Olympus. Percy makes it his goal to find Nico in The Battle of the Labyrinth, and later undertakes a small quest with the son of Hades in The Last Olympian. In addition, Nico was privy to the fact that there were two camps, one Greek and one Roman, before The Lost Hero, which makes him an important liaison between the two groups during the Heroes of Olympus series. The seven demigod protagonists of the second series also undertake a quest to save him when he is captured by Gaea's forces. Lastly, Nico brought Hazel Levesque, daughter of Pluto and his half-sister, back from the dead and helps her control her dangerous powers.

He also played a significant role in The Heroes of Olympus for when he promises Percy to be at The Doors of Death after Percy and Annabeth fall into Tartarus. Nico forms a slight bond with Jason after Nico is forced to confess in front of Cupid, and therefore Jason, that he has a crush on Percy. Later on in The Blood of Olympus Nico has to travel with Reyna and Coach Hedge to bring the Athena Parthenos to Camp Half Blood in order to restore peace between the Greeks and Romans. Along the way, Nico has to struggle with the burden of having to shadow travel the large statue and two other people. Nico eventually shadow travels to Camp Half Blood, extremely fatigued and continues on to battle with the camp and is shown to have been at fault for Octavian's death.

Nico appears in a supporting role in The Trials of Apollo series by providing explanation on the situation of the camp to Apollo, particularly, the current location of the other demigods of the New Great Prophecy. He and Will are also in a relationship.

Rachel Elizabeth Dare

Rachel is a main character in the later books of the Percy Jackson series and a minor character in the Heroes of Olympus series. Rachel is a mortal girl who can see through the Mist, the force that obscures gods and monsters from most mortals. She first meets Percy in The Titan's Curse at the Hoover Dam.[9] In The Battle of the Labyrinth, she helps Annabeth and Percy by guiding them through the Labyrinth to Daedalus's workshop. It is hinted throughout the series that she harbors some romantic feelings for Percy; Annabeth notices this and becomes jealous.[4] In The Last Olympian, she begins having strange visions and becomes the new Oracle of Delphi. Her first act as the Oracle is to deliver the next Great Prophecy about seven heroes, setting the plot of the Heroes of Olympus series. Her appearances in the sequel series is sparse; she is contacted by Annabeth in The House of Hades to ask for Reyna's assistance to bring the Athena Parthenos back to Camp Half-Blood.

Following the loss of Delphi to Python, as revealed in The Hidden Oracle, Rachel stops visiting Camp Half-Blood and begins in a frenzied attempt to regain her foresight, not helped by the disappearance of Apollo. Once informed of Apollo's arrival at Camp Half-Blood, Rachel returns and learns that not only Delphi is lost, so do three other Oracles, except for Dodona, which is owned by Rhea. She becomes upset upon learning of the existence of other Oracles, as Apollo has not told her before.

She is described as having red hair and freckles. She is skilled at painting and drawing, with both feet and hands, and is occasionally shown as a non-ADHD foil for her demigod teammates. Percy remarks on her ability to stand still for long periods of time at a charity event. Due to her limited power of foresight, Rachel knows a great deal of knowledge before she learns it herself; during her meeting with Reyna, she states the latter's full name, something that only Reyna's inner circle of friends know.

Clarisse La Rue

A daughter of Ares and the lead counselor of the Ares cabin at Camp Half-Blood, Clarisse is hot-tempered, courageous, and strong. As the child of a war god, she is an excellent fighter (usually utilizing an electric spear given to her by Ares) and a good military strategist. She can be stubborn and overconfident, much like her father, but often surprises other characters with her loyalty and leadership skills. Despite their similarities, Clarisse has a fear of her father and his anger at her if she should ever disappoint him—this, along with a strong sense of honor and pride, often motivates her actions. She also fears the Labyrinth because of what happened to the demigod Chris Rodriguez when he was inside the huge maze. She is aggressive towards most demigods, including Percy Jackson, though she does respect and make friends with a few: Percy, Annabeth Chase, and Silena Beauregard included. She eventually starts dating Chris Rodriguez.

Clarisse makes frequent appearances throughout the novels, first seen just after Percy Jackson arrives at Camp Half-Blood. In The Sea of Monsters, Clarisse is instrumental in bringing the Golden Fleece to camp. She is a main character in the short story "Percy Jackson and the Stolen Chariot" (published in Percy Jackson & the Olympians: The Demigod Files). In The Last Olympian, Clarisse initially sits out the war for Olympus due to a personal feud (like Achilles in the Trojan War[citation needed]). Enraged after the loss of her friend Silena, she later joins the battle with a fury reminiscent of her father's, slaying a drakon singlehandedly and receiving the blessing of Ares.[10] In The Blood of Olympus, Clarisse leads the Greeks in battle to defend the camp.

In The Hidden Oracle, it is stated that Clarisse had gone to to attend the University of Arizona.

In the film adaptation, Clarisse is portrayed by Leven Rambin.

The Heroes of Olympus main characters

Leo Valdez

Leo Valdez is a 15-year-old demigod, a son of Hephaestus, and the one of seven protagonists of The Heroes of Olympus. Leo is described as looking like a "Latino Santa's Elf" with curly black hair, dark brown eyes, a cheerful face, a slim build, and a mischievous smile. He is a Hispanic-American who speaks fluent Spanish. He befriends Jason at the "Wilderness School", although it is later revealed that everything that happened prior to the Grand Canyon museum trip is actually a trick of the Mist. Leo has the ability to create and manipulate fire, a skill that no son of Hephaestus has had in 400 years, and is also immune to heat/fire. When he was eight, he accidentally set fire to his mother Esperanza's machine shop while facing against Gaea, which resulted in Esperanza's death. Leo's remaining family blamed him for killing Esperanza and refused to take him in, resulting in Leo being put into several foster homes, which he constantly ran away from. He is also an excellent mechanic due to his father's abilities and has experience working with machines, as his mother was also a mechanic. He repairs a bronze dragon that was previously running wild in the camp's woods, renaming it Festus, which means happy in Latin. He also creates the Argo II, a ship the seven sail on to reach Greece.[8]

Leo tends to fall quickly for girls. He develops a crush on the minor goddess Khione in the first novel of the series. In The Mark of Athena, it is hinted he might have feelings for Hazel Levesque. Hazel discovers that Leo resembles her former boyfriend, Sammy Valdez. She suspects Sammy may be an ancestor of Leo's; in The Mark of Athena the two discover Sammy was Leo's great-grandfather.[6] In The House of Hades, he falls in love with Calypso, daughter of Atlas, during his stay in Ogygia.[11] Leo also uses his sarcasm and wit to hide his feelings, especially in regards to having been the cause of his mother's death. He also has a tendency to think of himself as the "seventh wheel" of the group, though he is just as important as the other six demigods of the quest.

In The Blood of Olympus, Leo plays a crucial role in defeating Gaea. He sacrifices himself to annihilate Gaea, and dies in the process. He is later brought back to life using the Physician's Cure (administered by Festus, his mechanical dragon) and returns for Calypso on Ogygia.[1]

Following his resurrection, Leo goes on a journey with Calypso and does not keep in touch with his friends for five months due to the difficulty of establishing communication; his return to Camp Half-Blood at the end of The Hidden Oracle is thus marred by multiple platonic beatings organized by Nico. As Leo is included in the prophecy of the Grove of Dodona, he accepts the task to accompany Apollo on his trials, together with Calypso.

Piper McLean

Piper McLean is a daughter of Aphrodite and the famous actor Tristan McLean. She is fifteen in The Lost Hero. Unlike most children of Aphrodite, Piper is not particularly concerned with beauty or fashion. Piper is mostly Cherokee on her father's side, and it is said that "[Her father] didn't really know what else [she was ethnically]".[citation needed] She has tan skin, eyes that change color constantly, and choppy caramel/chocolate-colored hair which she cuts herself. She is slim build and of average height. Her demigod "powers" include "charmspeak" (essentially, magical persuasion) and the ability to speak French. She is also occasionally able to see visions in her magic dagger Katoptris (meaning looking glass in Ancient Greek), which once belonged to Helen of Troy. It is unclear whether this is due to the knife's magic or her own.

Piper's relationship with her father is mutually affectionate but strained, in part because of the small amount of attention he spares for her. When she was young, Piper used her persuasive skills to "borrow" things (such as a car, lawn mower, etc.) just to earn a little of his time. After he is kidnapped by the giant Enceladus in The Lost Hero and subsequently rescued by Piper, Jason Grace, and Leo Valdez; Mr. McLean's relationship with his daughter begins to improve.[8] Piper is also very close to another character: Jason Grace. Though she later learns it was all a trick of the Mist, she was once his girlfriend while they attended the same school. She works hard to recreate this relationship in real life when she comes to Camp Half-Blood. She is also friends with all of the seven quest members in The Heroes of Olympus, especially Annabeth Chase.

Piper's main weapon is her dagger Katoptris, though she later acquires a magic cornucopia and uses it as a weapon. After being captured by pirates in The House of Hades, Piper asks Hazel Levesque to teach her sword fighting, using a jagged celestial bronze sword taken from one of the Boreads.[11]

In The Hidden Oracle, Nico mentions that Piper is currently attending school in Los Angeles, together with Jason.

Jason Grace

Jason Grace is a son of Jupiter (mythology) and the mortal Beryl Grace[citation needed], and younger brother of Thalia Grace. Jason has few memories of his mother, who was compelled to give him up when he was two, but he remembers enough about Thalia to not be surprised when he sees her again. Thalia reveals that their mother told her that Jason was dead, and that this was what finally drove her to leave home. He grew up at Camp Jupiter, the Roman equivalent of Camp Half-Blood, where demigods born to the Olympians' Roman aspects receive their training. In The Lost Hero, he begins a romantic relationship with the demigod Piper McLean.

Jason is described as having blond hair, blue eyes, and a scar above his upper lip (according to Thalia, this is the result of an attempt to eat a stapler when he was two). He is of above-average height, with an athletic build and muscular arms. He has a tattoo burned under his forearm, with twelve straight lines like a bar code, an eagle, and the letters SPQR over the lines. The tattoo symbolizes his twelve years of service in the Twelfth Legion Fulminata at Camp Jupiter; the eagle is a symbol of Jupiter.[8] By the age of fifteen, he had earned the rank of praetor and led the legion with his longtime quest partner, Reyna. Jason also coordinated the Roman camp's attack on the Titan force. He led an assault against Mount Othrys, a Titan stronghold near San Francisco, and defeated the Titan Krios in combat, much as Percy Jackson defeated Kronos.[8]

Of all the characters in the series, Jason is the one who struggles the most with the differences between the Greek and Roman perspectives. Piper McLean describes Jason as very rule- and duty-oriented, though the Roman god Terminus describes him as a "rule-flouter." However, when his former compatriot Reyna sees him again in The Mark of Athena, she comments that he seems to have lost some of his Roman qualities. When the Argo II is stuck in North Africa, he realizes that he must choose one identity or the other. He chooses to consider himself a Greek, despite his parentage, and is later unable to command a legion of ghosts sworn to obey only Roman officers.[6] During The House of Hades it is revealed that Jason has plans to return to Camp Jupiter to improve it with things he learned at Camp Half-Blood, such as giving the fauns (the Roman equivalent of a satyr) more rights and responsibilities.[11] Later, during The Blood of Olympus, Jason decides to consider both the Greek and Roman traditions as part of his heritage.[1] He becomes "Pontifex Maximus", a role which will see him travel between Camp Half-Blood and Camp Jupiter to build shrines for every god and goddess in the pantheon, allowing him to stay in touch with both sides.

Although Jason and Percy immediately recognize that it is best to work together, and become friends, their relationship is not without antagonism. As Percy puts it, it is natural for two powerful demigods to wonder which of them is stronger after a fight. Jason is a sword fighter like Percy, though they have different fighting styles. Jason uses an Imperial gold sword, styled as a Roman gladius, which he can extend into a pilum at will. It is possible that this is a trait common to all Roman demigods, as Reyna is also shown as able to turn her sword into a pilum.[citation needed] Jason also has power over air currents and can fly. He can sense and control some air spirits and has, like Thalia, called down lightning, which he conducts through his Imperial Gold weapons, even underwater.[1] On one occasion, he and Percy together summon a hurricane in Charleston harbor. Like his sister, Jason can also emit static shocks, which seem to be tied to his emotions.

The Hidden Oracle reveals that Jason has been attending school in Los Angeles with Piper, as per Nico's words.

Hazel Levesque

Hazel Levesque is a thirteen-year-old demigod, a daughter of Pluto (mythology) and Marie Levesque. She first appears in the book The Son of Neptune, at Camp Jupiter. It is later revealed that she has returned from the dead, assisted by Nico di Angelo. She grew up in the 1940s in New Orleans, where her mother had a gris-gris shop. When she was born, Pluto offered to grant her mother a wish, but her request for wealth backfired into a curse. As Hazel grew older, precious metals and gems would frequently come up out of the ground near her, more frequently if she was nervous. Her "wealth" was cursed, however, and brought misfortune to anyone who bought them from her mother. Gaea later convinces Hazel's mother to take her to Alaska by citing Hazel as a "cursed child", and tries to use Hazel's power over earth to resurrect her eldest son, the giant Alcyoneus, with a body made out of precious metals and stones. When Hazel's mother changes her mind about helping Gaea, Hazel buries herself and her mother under the earth, delaying Alcyoneus's rebirth and killing them both. While Hazel's spirit is being judged, she gives up the chance to go to Elysium to save her mother from punishment, and they are both sent to the Fields of Asphodel instead.

At some point before The Lost Hero, Nico di Angelo finds Hazel in the Underworld while investigating an imbalance between life and death. He helps her escape to the world of the living and arranges for her to join Camp Jupiter. Hazel and Nico are protective of each other, much as true half-siblings. In The Son of Neptune, Hazel joins Frank Zhang and Percy on a quest to free Thanatos, who tells her that her father, the Lord of the Dead, has not put out a "warrant" for her capture. By doing this, he has allowed her to live, but also doomed her to never be in contact with him again, because he cannot be seen openly flouting the rules of his own kingdom.

Hazel had a boyfriend, Sammy Valdez, in 1941. She later learns that Leo Valdez, who resembles him closely, is Sammy's great-grandson. Hazel's primary love interest during the series is Frank Zhang, though she hesitates to call either him or Sammy her "boyfriend" because of the word's different connotations in the present versus its meaning in the 1940s. She refers to having known and been friends with Jason before his disappearance. She also tames the highly-intelligent horse Arion, who eats precious metals.

Hazel is described as African American, having cocoa-colored skin, curly cinnamon-brown hair, and golden eyes. Her legion tattoo is described as looking like a cross with curved arms and a head. She eventually learns to manipulate her curse, manipulating precious stones and metals and sensing structures underground. She is an accomplished horse-rider and skilled with a spatha. She is unusually knowledgeable about the Underworld because of her time there. During The House of Hades the goddess Hecate insists that Hazel learn to use "magic", manipulating the Mist to create and break through illusions. Towards the end of The Blood of Olympus, Hazel becomes very gifted at magic and manipulating the Mist. After the Second Gigantomachy, Hazel is promoted to the rank of centurion of the Fifth Cohort, succeeding Frank (who becomes a praetor in The House of Hades).

Frank Zhang is a 16-year-old demigod, son of Mars and a Chinese-Canadian "legacy" (descendant of a demigod) who dies during military service in Afghanistan. He is taken care of by his grandmother after his mother's death, and makes his way to Camp Jupiter upon her insistence. Frank's family descends from Periclymenus, a grandson of Poseidon, who had the power to shapeshift. Periclymenus's descendants were sold into slavery in China, and migrated to Canada many years later. While battling Alcyoneus (who is invincible within Alaska), Frank taps into his ancestral power and transforms into an elephant. However, his combined power of being a son of Mars and having the ability to shapeshift makes his life very fragile. The Fates tied his life force to a piece of firewood when he was a baby; if the wood burns up, he will die (as in the ancient Greek legend of Meleager). The goddess Juno appears to his mother and grandmother while he is a baby to warn them of this fact, as he would be crucial to defeating the Giants. In all his life, Frank has ignited the wood twice, which he can do simply by thinking about it; the first time is while he is finding his way to Camp Jupiter, in bitter cold. The second time is when he, Percy, and Hazel travel to Alaska to free Thanatos. Eventually, Frank entrusts the firewood to Hazel, and in The House of Hades, Leo creates a fireproof pouch to contain it.

Frank has a meek disposition and is uncomfortable upon learning his father's identity publicly in front of the whole of Camp Jupiter. He suspected himself a son of Apollo, given his skill with a bow and arrow. On his quest in The Son of Neptune, and later during the series as well, he uses an enchanted spear given to him by Mars. To Frank's surprise, the spear summons a skeleton warrior that defeats the basilisks. Frank calls this skeleton "Gray".

As he has been residing in Camp Jupiter for no more than a year, Frank is initially considered a probatio, or rookie, of the Fifth Cohort. Before the quest to free Thanatos, however, his cohort's centurion, Gwen, decides to retire and give her position to Frank. Later, in The House of Hades, Jason surrenders his praetorship to Frank, who uses its authority and the Diocletian's Scepter to lead an army of Roman skeleton soldiers against the monsters in the Necromanteion.

Frank was described as 'cuddly' and 'fuzzy' and with a chubby, babyish face in The Mark of Athena, but in The House of Hades, after summoning the blessing of Ares to defeat a hoard of enemies, he transforms. He is then described as being taller, more muscular, and without all his childhood fat. Though now built like a professional football player, he is still as sensitive as before, and is embarrassed at his new appearance at first.

Initially, he was wary of the tension between Hazel and Leo, as Leo reminded Hazel of her old boyfriend, Sammy Valdez. After Leo's encounter with Calypso, however, Leo became more relaxed around Hazel and there were no more signs of anything other than friendship, much to Frank's relief. He then pursues a relationship with Hazel.

Reyna Ramírez-Arellano

Reyna Avila Ramírez-Arellano is 16 years old. She is a protagonist of the The Heroes of Olympus series. She is a demigod daughter of Bellona living at Camp Jupiter, and the younger sister of Hylla, the current queen of the Amazons. She was born in Puerto Rico and worked for Circe during the events of Sea of Monsters. She is described as intimidating and a natural leader; she has glossy black hair and black eyes. Reyna is generally more used to responsibility and the demands of leadership than many other demigods, as she is a praetor at Camp Jupiter—a title which she holds alone after the disappearance of her comrade Jason.[8] Reyna's demigod "power" is the ability to lend her strength, bravery, and courage to others near her.

Reyna is often accompanied by her dogs, Aurum and Argentum (Gold and Silver, who can sense if someone is lying) as well as her pegasus Scipio "Skippy". Scipio is put down by Reyna at end of The House of Hades after extreme exhaustion and being poisoned, much to Reyna's dismay.[11] Reyna seems to have a soft spot for animals. The immortal winged-horse named Pegasus recognizes this and awards her the title of "Horse Friend", an honor he has not bestowed for generations, because of her actions toward his descendants.

At the beginning of The Son of Neptune, she does not like Percy Jackson because he destroyed her childhood home on Circe's island, but she comes to regard him as a friend, ally, and possibly a love interest. In The Blood of Olympus more of her personal history is revealed as she, Nico, and Coach Hedge go on a quest to return the Athena Parthenos to Camp Half-Blood. While shadow-travelling on their way to New York, the trio stops in Reyna's home town of San Juan. While there, Reyna and the questers visit her old house while escaping from Orion, an old suitor of Artemis who is after her. There are several ghosts there, all calling Reyna a traitor and murderer.[1] Reyna reveals to Nico di Angelo that the Ramirez-Arellano family has always been favored by Bellona. Reyna's father, who is a war veteran, fell in love with the goddess, but later showed symptoms of PTSD and paranoia after his experiences in Iraq. When Reyna was ten years old, he became a mania, a ghost in which only the worst qualities of a formerly-living person remain. When the mania attacked Hylla, young Reyna had picked up the closest weapon and unknowingly killed her father. Reyna is reluctant to discuss the incident because patricide is "unforgivable" in New Rome.[1]

Coach Gleeson Hedge

Gleeson Hedge is a warlike satyr of Camp Half-Blood who has a prominent role in the The Heroes of Olympus series, though he is first mentioned in The Last Olympian as the writer of a letter sent to Grover. Like Grover, Hedge is also a guide for new demigods in searching for Camp Half-Blood, one of them being Clarisse La Rue. He disguises himself as a coach in the Wilderness School to oversee Piper and Leo (and later, Jason) before escorting them to Camp Half-Blood. He also serves as the adult chaperone for the crew of Argo II, assisting the demigods in their journey, and later accompanies Reyna and Nico to take the Athena Parthenos to Camp Half-Blood. Despite his toughness, Hedge does care for his comrades, but shows strictness towards the veterans (Percy, Annabeth, Jason, Nico, and Reyna). His favorite things are baseball bats, Chuck Norris, and screaming "DIE!" whenever the time arises. In The Lost Hero, Hedge falls in love with Mellie the cloud nymph and marries her; by the time of The House of Hades, Mellie is already pregnant with a satyr boy, Chuck, who is born at the end of The Blood of Olympus with Clarisse as his "godmother." In The Hidden Oracle, it is shown that he, his wife Mellie, Chuck, Piper, and Jason went to Los Angeles for the winter.

The Trials of Apollo main characters

Apollo

Apollo is the Seventh Olympian and the God of the Sun, Light, Music, Truth, and Healing. While he serves as supporting characters in several novels of Percy Jackson & The Olympians and The Heroes of Olympus series, he becomes the main protagonist of The Trials of Apollo series.

Apollo first appears in The Titan's Curse, where he transports Percy, Grover, Thalia, and the di Angelo siblings to Camp Half-Blood with his sun chariot, a flying red Maserati Spyder. Later, he indirectly assists Percy and company in rescuing Artemis from the Titans, even if doing so is explicitly forbidden by Zeus. At the end of The Last Olympian, Apollo chooses Rachel Elizabeth Dare as the new Oracle, a fate that she has been holding all the time. In the second series, it is revealed that Apollo being convinced by his legacy, Octavian's promises has led to the Olympians not realizing the Second Gigantomachy until almost too late, not to mention the resurgence of Python over Delphi. For these reasons, he and Artemis are banished from Olympus. He is convinced to give the cursed aster of Delos, in return for the "Valdezinator" that Leo crafted specifically for himself. After the war, the furious Zeus promises Apollo a punishment for his negligence.

The punishment is revealed to be a transformation into mortality in The Trials of Apollo series. Apollo has to endure a life as a mortal named Lester Papadopoulos. Following a meeting with two thugs and a demigod called Meg with whom he is forced into servitude, Apollo goes to Camp Half-Blood with Percy's assistance. There, Apollo has to adjust himself to a life of mortality while also slowly learning that Python is conspiring with the Triumvirate Holdings, whose member include his legacy Emperor Nero, in controlling the Oracles. Though he is able to protect the Grove of Dodona, Apollo is released by Meg after the revelation of her alliance with Nero, before heading to protect Camp Half-Blood from an attack by the Colossus of Nero. Afterward, Apollo embarks on a trial with Leo and Calypso in order to stop the Triumvirate while also finding Meg.

Apollo appears to be about 17 or 18 years old with sandy-colored hair, sky-blue eyes, and dazzling white teeth. When he is transformed into a human, though, he becomes a 16-year-old teenager with curly brown hair, blue eyes, acne, and a flabby torso. He is very narcissistic, prideful, arrogant, and lecherous, the latter trait earning him the status as the Olympian with the most demigods in Camp Half-Blood. His mortal transformation has quite tampered his ego, though, as he begins to realize how miserable humans are in facing the gods. In particular, he has grown to deeply care for Meg, and, though hurt by her betrayal, resolves to be with her no matter the cost.

In the film adaptation of The Lightning Thief, Apollo is played by Dimitri Lekkos.

Meg McCaffrey

Margaret McCaffrey, nicknamed Meg, is a 12-year-demigod daughter of Demeter and a main character in The Hidden Oracle. Her father was murdered by "the Beast" and she was subsequently adopted by Emperor Nero, unaware that the two are the same person. Nero taught her the arts of demigod and gave her a pair of crescent rings which can transform into sickles made of imperial gold, before giving her a task to lure Apollo into the Grove of Dodona. Meg appears to Apollo at an alley of Hell's Kitchen, Manhattan to defeat the thugs, sent also Nero, to stage "robbery". Meg demands Apollo's servitude and with him travels to Camp Half-Blood with Percy's assistance. There, Meg displays unusual abilities even before Demeter claims her, and later goes with Apollo to search for missing demigods and the Grove in the nearby woods, having to endure a brief abduction in the process. Her relationship with Nero is revealed at the climax, but her growing doubtfulness regarding Nero's ways, not to mention her already familial friendship with Apollo, leads her to rob Nero his chance on burning the Grove. While she helps Apollo bring the Grove alive, she severs their bonding spell and leaves.

Meg is described as small and pudgy, with dark hair chopped in a messy pageboy style and black cat-eye glasses with rhine-stones glittering in the corners. She is perky and adventurous, full of questions, and is also confrontational. She poses questions with no subtlety, something that Apollo is annoyed with but later comes to regard as a unique trait. Her abilities as Demeter's daughter allows her to connect better with nature as well as summoning a karpoi called "Peaches", a power that no other Demeter's demigods are known to possess.

Greco-Roman deities

Twelve Olympians

Though not all the gods who appear in Rick Riordan's novels are truly Olympians (that is, gods who live on Mt. Olympus), all Greek and Roman gods are generally considered to be a subset of the Twelve Olympians. As such, most characters in the series refer to these immortals generally as the "Olympian gods", to distinguish them from the Greco-Roman primordial gods and Titans.

  • Zeus/Jupiter – The 1st Olympian and the King of the Gods, Zeus is most prominent in The Lightning Thief[5] but has only small roles in the rest of Percy Jackson & the Olympians. Zeus is shown prominently throughout the series to be extremely narcissistic, paranoid and a fierce hypocrite. In The Lost Hero, under the influence of Khione, Zeus forbids contact between gods and mortals and closes off Olympus, although he indirectly helps the protagonists several times on their quests, such as answering his Jason's prayer for aid against Enceladus.[8] As the primary Olympian god, his demigod children reside in Camp Half-Blood's biggest cabin, Cabin 1, although there is only one person who resides there at the end of The Heroes of Olympus: Jason. In the film adaption, Zeus is played by Sean Bean.
  • Hera/Juno – The 2nd Olympian and the Queen of the Gods, she plays a role in The Titan's Curse,[9] by helping Percy and the others on their quest in The Battle of the Labyrinth.[4] As Juno in The Lost Hero, she is kidnapped by Gaea, and contacts Jason Grace to rescue her. Previously, as Juno, she had sneaked out of Olympus and switched Percy and Jason to try to unite the Roman and Greek demigods, going against the wishes of Zeus as part of a plan to defeat Gaea.[8] Her cabin in Camp Half-Blood is Cabin 2, the second biggest in the camp, but because she does not have demigod children, it is empty. In the film adaptation, Hera is played by Erica Cerra.
  • Poseidon/Neptune – The 3rd Olympian and the God of the Sea, Earthquakes, and Horses who is the brother of Zeus and Hades. In The Lightning Thief, he is suspected of having stolen Zeus's master bolt but is proven innocent after Percy recovers it.[5] Poseidon fights Oceanus in the underwater front of the Titan war. He remains there in The Last Olympian while the other Olympians fight Typhon, until Percy convinces him that his power is necessary to defeat Typhon. He was last seen fishing for giant sea serpents on Long Island Sound outside Camp Half-Blood.[10] Though he is referred to as Neptune in later books, he has yet to appear in Roman form. His cabin in Camp Half-Blood is Cabin 3, in which Percy is the sole permanent occupier. In the film adaptation of The Lightning Thief, Poseidon is played by Kevin McKidd.
    • Amphitrite – The Wife of Poseidon. She appears in one scene of The Last Olympian and is described as a beautiful goddess wearing armor, with black hair and small horns like crab claws.
    • Delphin – The God of Dolphins. Delphin is one of Poseidon's lieutenants in the war against Oceanus. He was seen briefly during a war council meeting in Poseidon's palace in The Last Olympian, in the shape of a dolphin.
    • Palaemon – The God of Sharks. Palaemon is one of Poseidon's lieutenants in the war against Oceanus.
    • Triton – Triton is a Sea God and Poseidon's "son and heir." He is depicted as a merman with two fishtails. He acts arrogant toward Percy but respects Tyson.
  • Demeter/Ceres – The 4th Olympian and the Goddess of Agriculture. She thinks the answer to everything is farming-related. Demeter made few appearances in the Percy Jackson and the Olympians series. She and her daughter Persephone appear in The Last Olympian, where they participate in the battle against the Titans.[10] Demetre's cabin in Camp Half-Blood is Cabin 4. In the film adaptation of The Lightning Thief, Demeter is played by Stefanie von Pfetten.
    • Persephone/Proserpine – The Goddess of Springtime and Queen of the Underworld. Persephone is the wife of Hades and the daughter of Demeter and Zeus. Hades only allows her to visit Demeter, her mother, in the spring and summer. She is said to be able to "soften" Hades and make him more merciful. Unlike most minor gods, she sides with Olympus during the war against the Titans.[10][12] In the film adaptation, Persephone is played by Rosario Dawson.
  • Ares/Mars – The 5th Olympian and the God of War who is the son of Zeus and Hera and the father of Deimos, Phobos, Eros, Clarisse La Rue, and Frank Zhang (as Mars). Ares is a callous bully who is driven by either greed, aggression, violence or by the promise of violence. However, as Mars, he dislikes war without reason and is one of the more important Roman Gods. He is however still a bully and is all for killing the Greeks. Percy first encounters Ares in The Lightning Thief, in which he drives a large black Harley-Davidson motorcycle with flame decals and a leather seat made from human skin. Percy defeats Ares in a sword fight near the climax of the book. Cabin 5 in Camp Half-Blood is the home of Ares' demigod children; it is said to be surrounded by all kinds of warfare apparatus, including spikes. In the film adaptation of The Lightning Thief, Ares is played by Ray Winstone.
    • Deimos – The God of Terror. A son of Ares, Deimos only appears in the short story "Percy Jackson and the Stolen Chariot" in The Demigod Files, where he torments Clarisse, forcing Percy and Clarisse to cooperate to defeat him.[13]
    • Phobos – The God of Fear. A son of Ares, Phobos only appears in the "Percy Jackson and the Stolen Chariot" story in The Demigod Diaries, where he torments Clarisse. He has the power to show people their greatest fears, but Percy and Clarisse cooperate to defeat him.[13] In The Blood of Olympus, a statue of Phobos is used by Piper to kill Mimas which fulfills the requirement of "one god and one demigod cooperating" in killing giants.
  • Athena/Minerva – The 6th Olympian and the Goddess of Wisdom and Battle Strategy who is the daughter of Zeus and Metis. Athena first appears in The Titan's Curse, where she dislikes Percy and his relationship with her daughter, and votes to execute Percy due to his crucial role in the fate of Olympus. She then argues that it was the most logical and wise choice. As Minerva, she is a scatter brain and lost. She hates the Romans for reducing her to that and tells her descendants to kill the Romans. She also leads her best children to the Athena Parthenos, although Aphrodite believes it to be subconscious, as Athena doesn't know where it is. Her color scheme is grey,[9] and her cabin in Camp Half-Blood is Cabin 6. In the film adaptation, Athena is played by Melina Kanakaredes.
  • Artemis/Diana – The 8th Olympian and the Goddess of the Moon, Wild Animals, Youth, and Hunting. Artemis is the daughter of Zeus and Leto and the twin sister of Apollo. Artemis, true to her vows, is a misandrist who discourages the companionship or value of men, and encourages maidenhood. As a result, she has no demigod children, but recruits Hunters who serve as her companions and attendants. Cabin 8 at Camp Half-Blood is dedicated to her, but because she is a virgin, the cabin is populated only when her hunters come to visit. In the film adaptation of The Lightning Thief, Artemis is played by Ona Grauer.
  • Hephaestus/Vulcan – The 9th Olympian and the Gods' Blacksmith. Hephaestus is the father of Charles Beckendorf and Leo Valdez. At Camp Half-Blood, Cabin 9 is dedicated to him. Hephaestus acts as a major ally of Percy in The Battle of the Labyrinth. In The Lost Hero, he defies Zeus by speaking to Leo through his dreams and he delivers the head of the mechanical dragon Festus for use as the figurehead for the Argo II. In the film adaptation of The Lightning Thief, Hephaestus is played by Conrad Coates.
  • Aphrodite/Venus – The 10th Olympian and the Goddess of Love and Beauty. Aphrodite first appears briefly in The Titan's Curse. Her appearance shifts constantly, always becoming more beautiful.[9] Cabin 10 at Camp Half-Blood is the home of her demigod children. In the film adaptation of The Lightning Thief, Aphrodite is played by Serinda Swan.
    • Eros/Cupid – The God of Love who is the son of Aphrodite and Ares. In The House of Hades, Jason and Nico convinced Cupid to give them Diocletian's Scepter. He eventually gives it to them after Nico admits that he has feelings for Percy. Jason muses that he prefers Aphrodite's version of love to Cupid's love.
  • Hermes/Mercury – The 11th Olympian and the Messenger of the Gods who is also the God of Travelers and Thieves. He is the son of Zeus and Maia. In the Percy Jackson and the Olympians series, Hermes helps Percy, hoping that he will be able to redeem Luke.[7] All unclaimed demigods are packed into Hermes' cabin called Cabin 11 because Hermes welcomes all travelers. In the film adaptations, Hermes is played by Dylan Neal in the first film and by Nathan Fillion in the second.
  • Dionysus/Bacchus – The 12th Olympian and the God of Wine and Parties who is the son of Zeus and Samele. Dionysus was made the head of Camp Half-Blood as punishment for pursuing "an off-limits wood nymph" romantically with it lasting for 100 years. Dionysus is portrayed as an extremely cynical and unfriendly misanthrope who does not appear to have much respect for other beings, except for Ariadne. He is a powerful god, but his powers are shown the least throughout the series. He has two demigod sons in the series who are named after Castor and Pollux, both of whom are the sole inhabitants of Cabin 12.[5] Dionysus hates his job and has a low opinion of demigods like Theseus's abandonment of Ariadne.[7] In The Last Olympian following Kronos' defeat, Dionysus work at Camp Half-Blood is reduced to 50 years. Dionysus is played by Luke Camilleri in the first film and by Stanley Tucci in the second.
  • Hades/Pluto – The unofficial 13th Olympian and the God of the Underworld. Hades, like Zeus and Poseidon, is considered an "elder god," one of the most powerful to be born of Kronos and Rhea. The eldest and most intelligent of the Big Three, Hades is an isolationist who distances himself constantly from other Gods because they do the same to him, out of fear. They continuously underestimate Hades, who is in fact a very honorable and fatherly individual. He is the father of Nico, Bianca, and Hazel. After the Second Titanomachy, Hades is granted Cabin 13, which is populated by his sole living Greek demigod child, Nico. In the film adaptation of The Lightning Thief, Hades is played by Steve Coogan and is depicted as also having a fiery winged demon form.
  • Hestia/Vesta – The Goddess of the Hearth and Home. She is simultaneously the oldest and the youngest of the Olympians, because she was the first-born of Kronos and Rhea, yet she was regurgitated from Kronos' belly the last. Like Artemis, Hestia swore the vow of chastity so no conflict can spring up about her allegiance; as a result, she does not have any demigod child. Hestia gives up her golden throne on Olympus to Dionysus/Bacchus in order to keep the peace on the Olympian counsel. She is the title character of The Last Olympian, wherein she helps Percy figure out how to defeat Kronos. She is described as preferring the shape of a young girl with a soft voice. In Percy Jackson's Greek Gods, Percy speculates that she may have helped Prometheus give fire to humans out of kindness. She does not mind being overlooked.
Minor Greco-Roman gods

  • Aeolus – The Master of the Four Winds. In The Last Olympian, he manipulates the winds to form a barrier around Olympus that protects it from air attacks from the Titans.[10] In The Lost Hero, he is portrayed as frenetic and unbalanced by attempting to fill all the requests of the gods and hopes to be made god of the Wind. He hosts a weather report that airs every 12 minutes.

Primordial deities

The Primordial Deities are the deities that came before the Titans and the Olympians came into existence. Among the known Primordial Deities are:

  • Gaea/Terra – The embodiment of Earth who is the primary antagonist of The Heroes of Olympus series. Gaea is the wife of Ouranus, and mother of the Titans, the Elder Cyclopes, the Hecatonchires, the Giants, and Antaeus. She is the grandmother of the Olympians, whose rule she resents. As of The Son of Neptune, she remains sleeping in the ground, but retains some consciousness and influence. Like Kronos, she commands an army of mythological figures and monsters dissatisfied with the Olympians. During The Blood of Olympus, she is defeated by Leo Valdez, Piper McLean and Jason Grace who lift her into the sky, charm her to sleep and then incinerate her with a mighty blast of fire combined with a shot from an onager by Octavian. As a goddess she can't be killed, but like her son Kronos, her essence is scattered so much she hopefully will never able to form a consciousness again.
  • Akhlys – The Goddess of Misery and a daughter of Chaos and Night. She is described as a miserable-looking old woman who carries the Aegis shield with Medusa's head carved into it. In The House of Hades, she offers the Death Mist to Percy and Annabeth, but later betrays them by luring them into Nyx's territory and trying to kill them with poison. In anger, Percy manipulates the poison back at Akhlys, causing her to run away in fear. This is the first time that Annabeth sees the darker part of Percy's personality.
  • Keto – A Primordial Sea God in Greek Mythology and the sister of Phorcys. In The Mark of Athena, Keto appeared as a girl named Kate who is encountered in Phorcys' aquarium. When Gleeson Hedge discovered Phorcys' ruse, he freed Percy and Frank after knocking Kate out. After Percy, Gleeson, and Frank escape from the aquarium, Keto sent Skolopendra after them.
  • Nyx – The primordial Goddess of Night who resides at the Mansion of Night in Tartarus during the day. She is said to be the oldest being in the universe besides Chaos itself, and her residence, which is close to Chaos, is "worse than Medusa's head".[citation needed] In The House of Hades, Percy and Annabeth accidentally wander into Nyx's territory and try to pose as tourists guided by a brochure that does not mention Nyx. Angered, Nyx shows just how important she is and summons her children, who emit pitch-black darkness that even Nyx herself cannot see through it. Before she could catch them, the couple leave through the Mansion of Night. Nyx is described by Annabeth to be "as tall as the Athena Parthenos, but very much alive."
  • Ourea – The Ourea are the primordial Gods of the Mountains who are the children of Gaea. In The House of Hades, there were some Ourea that make up the Apennine Mountains. When the Argo II tried to cross the Apennine Mountains, the Ourea there attacked them with boulders due to them being loyal to Gaea. They hurled boulders from their mountaintops where they severely damaged the Argo II. Leo Valdez had to turn the Argo II away from the Apennine Mountains in order to come up with a different plan.
  • Phorcys – A primordial Sea God and the brother of Keto. In The Mark of Athena, he and Keto run an aquarium in Georgia which contains a lot of rare sea monsters. Following a VIP tour, Phorcys traps Percy and Frank in a tank to fight each other. This attracts the attention of Gleeson Hedge, who manages to break the glass tank as they escape promising to return and free the sea creatures that Phorcys has in captivity.
  • Tartarus – While Tartarus is the name of a location where the Titans were imprisoned, there is a primordial god by that name as well. Through Gaea, Tartarus fathered Typhon and the Giants. His real form is the whole Tartarus itself, but he personifies himself in a form that stands several feet tall with a face of a swirling vortex and a voice that makes it seem going inward, rather than outward.In The House of Hades, the personification of Tartarus appeared in physical form where he makes a remark about Gaea's awakening. Percy and Annabeth fought Tartarus until Iapetus and Damasen sacrificed themselves so that Percy and Annabeth can get out of the Underworld.
  • Uranus - The embodiment of the Sky who is the husband of Gaia and the father of the Titans. When Gaia gave birth to the Elder Cyclopes and the Hekatonkheires, Ouranus hurled them into the pits of Tartarus out of spite of their appearances. Kronos later castrated Ouranus before cutting him to pieces. Ouranos then cursed Kronos, stating that his child would come to overthrow him just as he had. Not much was mentioned about Ouranus afterwards. In Percy Jackson's Greek Gods, Percy Jackson described Ouranus to be tall and muscular with long dark hair and his skin changed depending on if it is day or night.

Titans

The Titans are the children of Gaia and Uranus. Most of them fought against the Gods during the Titanomachy which ended with the Gods winning. Among the featured Titans are:

  • Kronos/Saturn – The King of the Titans and the Titan of time. Kronos is the main antagonist of the Percy Jackson & the Olympians series. He is the megalomaniacal father of Zeus, Poseidon, Hades, Hera, Demeter, Hestia, Chiron, and thus the grandfather of Percy, whom he attempts to recruit into the Titan army. Kronos is the most powerful Titan of all, with the ability to accelerate, decelerate and freeze time itself, but he is also a master of manipulation and is extremely intelligent. He fights with a scythe with a six-foot-long magical blade that can harm both gods and mortals.[4] During the series, Kronos is initially trapped in Tartarus, but he eventually escapes to the point where he can possess Luke's body. In this form, he leads the Titan army against Olympus while Typhon occupies the Olympians' attention. He is eventually defeated after an intense battle with Percy, when Annabeth convinces Luke to destroy him. However, according to Hermes, he is not dead as Titans can't be killed anymore than gods can. His essence has been scattered to the wind and he has hopefully been scattered so thin he will never be able to form a consciousness again, let alone a body.[10] In Percy Jackson: Sea of Monsters, Kronos is voiced by Robert Knepper. He was shown to have a gigantic, demonic body along with superhuman strength and the ability to use parts of his own body as projectile weapons. It should be noted that this is the first time ever that Kronos is seen in full force since the novels depict him hiding in the shadows of Tartarus, reforming in his sarcophagus, and possessing Luke.
  • Rhea - The Queen of the Titans and the Titaness of Motherhood. She is the mother of Zeus, Poseidon, Hades, Hera, Demeter, and Hestia. Unlike Kronos, Rhea loved the children that she gave birth to and even kept Zeus from being eaten by replacing him with a stone. When it came to the Titanomachy, Rhea advised her nephews and nieces to remain neutral. Only Atlas sided with Kronos. Since Kronos' defeat, Rhea retreats to Upstate New York but continues to keep in touch with her children. In The Hidden Oracle, Apollo learns that the Grove of Dodona, which is under Rhea's control, is the only one yet to be conquered by Nero. Rhea subsequently appears to Apollo to offer him advice. She is a hippie and attended the Woodstock.
  • Aigaios – Aigaios is a partner of Oceanus who assists in the Titans' war against Poseidon. In The Titan's Curse, Tyson reports that Aigaios protected the Princess Andromeda (a cruise ship carrying the Titan Army) from Poseidon.
  • Atlas – The general of the Titan army. He is the father of Calypso, Zoë Nightshade, and the Hesperides. Atlas was imprisoned on a mountaintop near San Francisco, forever cursed to hold up the sky. Atlas is extremely powerful, even for a Titan, and is a person of incredible physical strength, this being his ultimate power. He served as the primary antagonist in The Titan's Curse, when Kronos's forces captured Artemis and forced her to take his place. Percy helps Artemis subdue him and force him back under the sky.[9] In The Last Olympian, Atlas was referenced by Kronos, who decides not to free him.[10]
  • Hyperion – Lord of the East. Hyperion is the father of Helios and Selene, the Titans of the sun and moon, respectively. He appears in The Last Olympian, where he is clad in full golden armor and battles Percy. Grover traps Hyperion by turning him into a tree.[10] In The House of Hades, Hyperion is seen reforming in Tartarus. He and Krios are later seen guarding the Doors of Death. Both are obliterated by Tartarus when he shows up to fight Percy and Annabeth.
  • Iapetus – Lord of the West. First seen in The Demigod Files, when Percy drags Iapetus into the river Lethe, erasing his memory. Rather than kill him, he renames him "Bob" and sends him to work for Hades. Nico treats Bob kindly[14] In The House of Hades, Percy and Annabeth reunite with Iapetus, who states his wish to see the sky again after having been in the Underworld for a long time. Annabeth is afraid that he will regain his memories by meeting with his fellow Titans, but Iapetus continues to help them and later sacrifices himself to fend off Tartarus while the two cross the Door of Death. In the outside world, Percy fulfills Iapetus' wish by looking at the sky and saying "Bob says Hello".
  • Koios – Lord of the North. In The House of Hades, Koios is briefly seen in Tartarus. He greets Bob/Iapetus, not realizing his memory loss, inadvertently reminding him of several events in his past. Koios assumes Iapetus has returned to the side of the Titans and tells Iapetus that he plans to complete the Titans' assault on Olympus and they, not the giants, will rule the world, with Gaea's eventual acquiescence. He mentions that his daughter Leto had been mistreated by Zeus after "she bore him those fine twins" (Apollo and Artemis). Koios then hurries off to meet up with Krios and Hyperion at the Doors of Death. Percy describes Koios as having Apollo's smile and Artemis's eyes.
  • Krios – The Titan of stars and the constellations and Lord of the South. Percy sees Krios in a dream where he guards Atlas. He wears armor decorated with glowing stars. In The Lost Hero, Jason claims to have defeated Krios in single combat on Mount Orthys. In The House of Hades, Krios is seen with Hyperion guarding the Doors of Death. Both of them are obliterated by Tartarus when he appears to fight Percy and Annabeth.
  • Oceanus – The Titan of the Ocean. Oceanus is depicted as having the upper body of a muscular man with a long beard and horns and the lower body of a serpent. He did not fight the Olympians in the original Titanomachy, but in The Last Olympian, he assaults Poseidon's forces underwater. Oceanus is incredibly powerful being the only being who can truly fight on par with Poseidon where the resulting fight leveled Poseidon's palace. In fact, the intense battle between the two Sea Lords lasts for days and is so vicious that it creates destructively violent storm waves and tsunamis. Though the true winner of this battle is never specified but theoretically it was Poseidon. After the defeat of Kronos, Oceanus escapes back to the depths of the ocean.[10]
  • Prometheus – The Titan of Forethought. Like Oceanus, Prometheus prefers to fight for the more powerful side. He supported the Olympians in the Titanomachy but joins the Titan army in the Percy Jackson & the Olympians series because he believed that the Titans would win. Prometheus is sent to discuss a truce with Percy and Thalia during the Battle of Manhattan. He flees after Kronos's defeat, sending a list of excuses to Mount Olympus.[10]

The last in the Julio-Claudian dynasty, Nero is infamous for his tyranny and overindulgence in wealth and luxury with little regard to his subjects. The Trials of Apollo series reveals that Nero is alive and well long after he is thought to be dead and has amassed followers and wealth through his Triumvirate Holdings, of which he is a member. As "the Beast", Nero killed Meg's father but later adopted and trained her in demigod arts so she could eventually lure Apollo into the Grove of Dodona.

Legacies

The following are mentioned not as direct children of the Olympians, but as grandchildren, great-grandchildren, or the like:

  • Bryce Lawrence – A legacy of Orcus. In The Blood of Olympus, Bryce is seen by Nico di Angelo in a dream. Despite being banished from Camp Jupiter by Reyna years ago for having killed his own centurion, Octavian allows him to return turning a blind eye to his cruelty towards the rest of his fellow cohort when he first joined the legion. He is given his probatio necklace and is assigned to the Fifth Cohort. In South Carolina, Bryce overhears Reyna's story of killing her father, and tries to capture her and take her to Octavian to charge her with the crime of patricide. He then is turned into a ghost by Nico and forced into the Underworld.

He reads the auguries for Camp Jupiter. After Jason Grace disappears, he campaigns to succeed to Jason's position as praetor. He is suspicious of the amnesic Percy Jackson when he arrives at Camp Jupiter, deducing he is a Greek demigod, rather than Roman. Mocking him and attempting to undermine his quest. When demigods from Camp Half-Blood arrive at Camp Jupiter, Octavian declares the Greeks invaders and urges the Romans to fight them off, believing the Greeks to be in league with Gaea. His warmongering escalates further in The House of Hades where he violates direct orders from Reyna not to attack Camp Half-Blood after leave him in command of the Legion. He is thin and blonde. He is also said to "look eighteen but could probably pass as younger." He dies in The Blood of Olympus where he launches an onager attack on Gaea during her defeat. His foot gets tangled in the launching rope and he is launched along with the payload and dies in the explosion. As his effort may have helped defeat Gaea, Octavian is hailed as a hero and his true actions covered up.

Mythological figures

The following characters from Greek mythology appear in this series. Most of them are the direct children of gods or Titans, but a few are mortals with such great power that they are able to influence the realm of the gods.

  • Achilles – The son of Thetis and Peleus. The ghost of Achilles appears briefly in The Last Olympian, warning Percy about the Curse of Achilles.
  • Calypso – Calypso is the daughter of the titan Atlas who is imprisoned on the island of Ogygia for supporting her father during the first titan war.[4] She first appears in The Battle of the Labyrinth, where she nurses Percy back to health.

Percy asks the gods to release her at the end of The Last Olympian,[10] but she is still residing there of The House of Hades, when Leo becomes trapped on Ogygia. She ends up falling in love with him. After Leo escapes, he swears that he will return for Calypso. At the end of The Blood of Olympus, Leo gets back to Ogygia and frees Calypso. They then soar into the unknown on the back of the mechanical dragon Festus. In The Hidden Oracle, Calypso comes to Camp Half-blood with Leo and reveals that, due to her choice to leave Ogygia, she has become a mortal. She seems to dislike Apollo's company due to a past relationship that went awry, although she has to accompany him on his trials, together with Leo.

  • Circe – Circe ran a magical beauty boutique in the Sea of Monsters, where she went by the alias of C.C. While she treated females at her spa, she turned males into guinea pigs. When Percy was turned into a guinea pig, Annabeth used multivitamins from Hermes to restore him, and together they defeated Circe. In The Heroes of Olympus series, it is revealed that Circe employed Reyna and Hylla after they left Puerto Rico and treated them nicely, at least until the pirates were freed and proceeded to capture the sisters.
  • Daedalus – Architect of the Labyrinth, Daedalus is the son of Athena and the father of Icarus. He killed his nephew Perdix but escaped eternal punishment by casting his soul into automatons. Athena branded him with a murderer's brand in the shape of a partridge. In The Battle of the Labyrinth, Daedalus appears under the alias of a Camp Half-Blood worker named Quintus (meaning 'the fifth' in Latin). Percy and Annabeth convince him to use his technical genius to help defeat the Titan army in the Labyrinth.

In death, he becomes the Underworld's architect and is allowed to visit Icarus and Perdix on weekends.[4]
  • Eurytion – Eurytion is a son of Ares who works on Geryon's ranch. He appears in The Battle of the Labyrinth and helps Percy and Annabeth locate Hephaestus.
  • Heracles/Hercules – Heracles is regarded as one of the greatest of Ancient Greek heroes of all time. He is the son of Zeus and Alcmene. Following his death, Zeus brought him up to Mount Olympus to live with him and he was engaged to Hebe. Heracles was mentioned but did not appear in the first book series, usually when monsters that he had fought show up to trouble Percy. In The Titan's Curse, it is revealed that Zoë Nightshade helped Heracles steal the Apples of the Hesperides and gave him a magical sword Riptide which he had forgotten to return, leaving her to be disowned by her sisters and giving her no credit for her help. Hercules appears in The Mark of Athena where he was tasked by Zeus to guard the Pillars of Hercules and issues Piper and Jason a quest for permission to enter the Mediterranean Sea.
  • Hyacinthus – Hyacinth was a beloved lover of Apollo. The right for him was contested between Apollo and Zephyrus, and when the former refused to share, Zephyrus caused an accident that led to Apollo's accidental killing over Hyacinthus. His death is regarded by Apollo as one of his two greatest losses of his life, together with Daphne's petrification; to this day, Apollo is still haunted by visions of him.
  • Irus – While not strictly a suitor, Irus is a beggar who ran afoul of Odysseus upon his return to Ithica. In The Blood of Olympus, Jason posed as Irus to get close to the ghosts of the Suitors of Penelope.
  • King Midas – King Midas was a king who possessed the golden touch which turned anything he touched to gold. He is among the people brought back to life by Gaea in The Lost Hero where his Golden Touch was restored upon him and his son Lityerses emerging from the Doors of Death. It has been mentioned that Midas has occasionally turned Lityerses to gold by mistake causing him to use the nearby lake to wash the gold off him. Jason, Piper, and Leo come to Midas's mansion in Omaha, Nebraska. He was initially polite before revealing his allegiance and turning Leo and Piper into solid gold. Jason fought back against Midas and Lityerses and managed to restore Leo and Piper to life.
  • King Minos – King Minos is a former king who becomes one of the judges of the Underworld. Nico consults him in The Battle of the Labyrinth, but Minos kidnaps Nico and tries to kill Daedalus, who constructed the Labyrinth for him. When Daedalus later ends up in the Underworld, Minos unsuccessfully tries to convince the other two judges to punish Daedalus.[4]
  • King Sisyphus – A former ruler of Corinth. He had committed violations of guest hospitality, seduced his niece, plotted to kill his brother Salmoneus, and told the River God Asopus where Zeus had his daughter. His major crimes involved cheating death twice. The first where he tricked Thanatos into showing him how the chains worked causing Thanatos to be trapped until Ares freed him (Thanatos being trapped displeased Ares since no one in battle could die). The second time was when he complained to Persephone that his wife Merope did not give him a proper funeral and sent Sisyphus' spirit to the living. Even when Sisyphus did not want to return to the Underworld, he was forcefully dragged back there by Hermes. His punishment in The Fields of Punishment was to push a boulder up a hill. When it got close to the top, the boulder would roll back to the bottom and Sisyphus was condemned to begin again. He appears in The Demigod Files in the story titled The Sword of Hades when Percy and Nico ask him advice while Thalia pushes the boulder up the hill. He does not really help them much, but he does say that he helped someone else. He said that he told that other person to go see Melinoe. Therefore, Percy and his friends go to see Melinoe as Sisyphus begs for them to set him free from his punishment for being here was a minor set-back.[14]
  • King Tantalus – Tantalus is the spirit of a king from the Fields of Punishment who is the son of Zeus. He ended up there after killing his son Pelops, cutting him up, and serving him as food to the Gods. His punishment in the Fields of Punishment was to stand under a fruit tree in the middle of a lake. When he tried to pluck the fruit to eat, the branches of the tree rose out of his reach and when he bent down to drink the water, the level would retreat. Tantalus became "tantalised" by having food and drink close to him, but unable to enjoy either. He becomes the activities director at Camp Half-Blood after Chiron is fired. He appears in The Sea of Monsters as a minor character. Even when hired as the activities director, he could not eat or drink as the food kept evading him. Tantalus is shown to hate Percy and his friends even more than he hates most half-bloods, yet shows favoritism to Clarisse, as when naming her hero when the camp was attacked by Colchis Bulls or when she wins the chariot race and throwing a banquet in her honor. When Tyson is brought to camp, Tantalus insults and makes fun of him even when Tyson is claimed by Poseidon. When the camp is attacked by a large flock of Stymphalian birds, Tantalus blames it on Percy, Annabeth, and Tyson's "bad chariot driving" despite that they were the ones who defeated the birds. At the end of the book, his curse is lifted by Dionysus just before he is sent back to the Underworld as he attempts to take some food along, though none of the campers are sad to see him go.
  • Medea – Medea is a sorceress and a granddaughter of Helios. Jason, Piper, and Leo encounter her in The Lost Hero, where she runs a mall in Chicago. She becomes enraged upon learning Jason's name which he shares her husband, a hero who left her. Her magic causes Jason and Leo to become hostile to one another. Realizing Medea is an agent of Gaea, Piper brings them to their senses and leads their escape before Medea can do anything else to them by blowing up the mall and killing her again.
  • Muses - The Muses are the immortal daughters of Zeus and the Titan Mnemosyne. They inspired and presided over several creative arts. In The Lightning Thief, the Muses performed on Mount Olympus at the time when Percy returns Zeus' Master Bolt. As the gods celebrate, the Muses play music that sounds like anything you want, so no one argues about the music. In The Titan's Curse, the Muses perform their music after the Gods decide not to kill Percy and Thalia. According to Percy, everybody hears the music they only want to hear, like classical for the gods and hip hop for the younger demigods. In The Last Olympian, a few Muses are shown playing some tunes on Olympus. Their hearts were not into it because of Kronos' attack on Mount Olympus while the Gods were out fighting Typhon.
  • Narcissus – Narcissus was a hunter who was renowned for his beauty and disdained those that had loved him. Nemesis puts a spell on him that causes him to fall in love with the reflection of himself in the water where he dies upon not being able to leave his own reflection. In The Mark of Athena, Narcissus is encountered by Hazel Levesque and Leo Valdez at the Salt Lake in Utah where the demigods are looking for the Celestial Bronze which is needed to help repair the damaged Argo II. When Narcissus realizes that Hazel and Leo have managed to steal his bronze plate which he uses to be able to admire his own reflection, he and a mob of nymphs runs after them trying to kill them.
  • Pasiphaë – A Greek sorceress and a daughter of Helios who appears in The House of Hades. She is resentful of the gods for punishing her by giving birth to Minotaur, while her husband, Minos, who caused the problem in the first place, enjoys the right as a judge in the Underworld for being Zeus' son. She is allied with the giants and does a battle of sorcery with Hazel, who manages to trick her into entering an imaginary trapdoor in the Labyrinth.
  • Phineus – A blind seer who appears in The Son of Neptune. Percy Jackson finds him in Portland where the Harpies are trying to steal his food. Before he dies from Gaia making him choose a poisoned cup, he reveals to Percy the location of Alcyoneus' camp.
  • Procrustes – Procrustes is the son of Poseidon who is depicted as a half-giant in this franchise. He is a rogue thief and blacksmith who was previously defeated by Theseus.

Percy defeats him by using Riptide on him.
  • Sciron – Scrion is a thief who is the son of Poseidon. He had previously fought Theseus in the past. In The House of Hades, Sciron and his Giant Sea Turtle waylaid the Argo II on the coast of Croatia. Like his fight with Theseus, Hazel defeated Sciron by pushing him off the cliff where he was gobbled by the Giant Sea Turtle.
  • Theseus – A hero who is the son of Poseidon and younger than Percy had assumed. When Nico was trying to summon Bianca in The Battle of the Labyrinth, he ended up summoning the spirit of Theseus.

Other Greco-Roman beings

Greco-Roman humanoids

Many of the beings and creatures of Greco-Roman myths are humanoid—in other words, they possess both the intelligence and some of the physical features of humans. The vast majority of these creatures are friendly, such as nymphs and centaurs. Unlike the majority of Greek creatures, these beings are also unquestionably sentient and tend to have larger roles in the novel series.

  • Agrius and Oreius – Agrius and Oreius are humanoid bears that were a result of a union between a woman named Polyphonte and a bear due to the power of Aphrodite. They were also the great-grandsons of Ares due to Polyphonte being Ares' granddaughter. The two served as Luke's henchmen in The Sea of Monsters.
  • Amazons – The Amazons are a tribe of female warriors who usually worshiped goddesses like Hera and Artemis. Some Amazons appear in The Son of Neptune where they are sent to their compound at Reyna's request. They also run the billion-dollar Amazon.com, which they use as a source of cover and revenue. Though they are often confused with the Hunters of Artemis, the Amazons are not misandrists and like men just fine; they are just a very matriarchal society in which their male spouses are made to work in manual labor while the Amazons work as administrators. In The Blood of Olympus, the Amazons collaborate with the Hunters of Artemis to protect Reyna from Orion, resulting in many casualties.
    • Hylla Ramírez-Arellano is the older sister of Reyna, the praetor of Camp Jupiter; she is 22 years old. She is a demigod daughter of Bellona and the Amazon Queen. She looks a lot like Reyna with beautiful, glossy black hair and black eyes, long lashes, and a scar on her forehead. She as her sister had the bearing of a swordswoman but stronger. Hylla wears a black suit with a golden belt. Reyna describes her sister as a "chameleon" because she is always changing. They have similar personalities but Hylla seems more funny and "chill". She was born in Puerto Rico and worked for Circe during the first series with her sister. She also spent a year living with pirates and winning the crew's respect. She had an awful childhood, basically she was always trying to protect her sister from their dad. Her father was in the army and the whole Ramírez-Arellano family was favored by Bellona. While worshiping her, Hylla's father falls in love with the idea of war and Bellona. They have the two kids together. Later, the father shows symptoms of PTSD. It turned out he had become a mania, or an insane soul with the worst qualities, and was no longer human. The mania knocks out Hylla, Reyna think she is dead and unknowingly kills her father, who was, technically, already dead. All that was left was the crazed and obsessed remnants of the soul.In "The Blood of Olympus", the Amazon have been working with The Hunters of Artemis who kidnap Reyna and take her to an Amazon headquarters, where Hylla reunites with her sister. Orion breaks into the Amazon HQ and kills every Hunter and Amazon, but the girls escape to their old house, and try to defeat Orion without success. Hylla orders Reyna to leave because she had to stay in combat with the supervivients, hunters, and some Amazons. Though she is never seen afterwards, Orion later confirms that Hylla is still alive after battling him, much to Reyna's relief.
    • Kinzie – An Amazon who is the daughter of a nymph and is close and loyal to Hylla. She disarmed Percy and sent Frank flying across the room in "The Son of Neptune." Kinzie also cornered Percy during the Feast of Fortuna and asked Percy out, though he declined. In The Blood of Olympus, Kinzie is killed by Orion.
    • Lulu – An Amazon guard who is loyal to Otrera. In The Son of Neptune, Lulu guarded Percy Jackson and Frank Zhang.
    • Otrera – A daughter of Ares and the first Queen of the Amazons who was originally killed by Bellerophon. In The Son of Neptune, she is revealed to be among those who emerged from the Doors of Death. She challenged Hylla for the title of Queen of the Amazons. When she planned to defeat Hylla, Otrera plans to have the Amazons help Gaea and the Giants destroy Camp Jupiter. Hylla manages to defeat Otrera twice until Thanatos is freed from the chains where he was trapped, making sure she would not rise from the dead and challenge her again.
  • Arachne – Arachne was once a female weaver who was turned into a spider by Athena after she won in a weaving contest against Arachne. In The Mark of Athena, Arachne appears as a spider-like monster who is the last obstacle for Annabeth's quest to the Athena Parthenos and is in collaboration with Otus and Ephialtes. Annabeth challenges Arachne to a weaving contest where Annabeth tricks Arachne into making monster-sized Chinese handcuffs which Annabeth places onto Arachne. When Annabeth states to Arachne that the Athena Parthenos will restore Mount Olympus, Arachne goes into a fit and brings down her chamber enough to open a chasm to Tartarus. As Arachne falls down into Tartarus, she manages to ensnare Annabeth at the last minute as she and Percy go down the chasm with Nico promising to meet them at the Doors of Death. In The House of Hades, Arachne ambushes Percy and Annabeth which ended with Percy using Riptide to defeat Arachne.
  • Antaeus – Antaeus is a half-giant who is the son of Poseidon and Gaea. He was invincible as long as he maintained contact with the ground, so Percy defeated him by hanging him in the air with chains.

He gave Percy an apparently impossible task; cleaning out the stables of carnivorous horses, one of the Labors of Hercules. Percy managed to complete the task, but Geryon went back on his deal to let Percy's friends free and the two fought. Percy found Geryon a strong opponent, as Geryon's three hearts made him almost impossible to defeat.

    • Mrs. O'Leary – Mrs. O'Leary is the only friendly hellhound to ever exist. Quintus (an alias of Daedalus) was her original owner, but, after asking Nico di Angelo to kill him, Percy becomes the hellhound's owner.

It was destroyed by the cannons of the CSS Birmingham. In The Mark of Athena, Percy fights a Hydra when he, Jason, and Piper are on a mission to rescue Nico from Ephialtes and Otis. In The Lightning Thief film, the creature takes the form of five janitors (played by Tom Pickett, Keith Dallas, V.J. Delos-Reyes, Spencer Atkinson, and Tim Aas) in the Parthenon replica in Tennessee and refers himself as "We." The Hydra is ultimately defeated by the use of Medusa's head.
  • Hyberborean – The Hyperboreans are a race of 30 ft. Snow Giants with blue skin ice-gray hair that come from Hyperborea. When wounded, the Hyperborean will bleed blue blood. They can freeze object and people using their frosty breath. When defeated, the Hyperborean freeze into ice.

  • Nemean Lion – The Nemean Lion is a lion that is one of the children of Echidna and Typhon. It has a hard skin in which no weapon can penetrate. Luke and Atlas sent the Nemean Lion to the National Air and Space Museum to stop the group of questing Hunters and Demigods.

She/He appears in The Titan's Curse and The Last Olympian.
  • Pegasus – Pegasi are winged horses that are named after the original mount of Bellerophon that was born from the blood of Medusa.
    • Blackjack – He is the pure black Pegasus and Percy's loyal friend.

    • Scipio – Reyna's Pegasus who appears in The Son of Neptune. His nickname is "Skippy" because he's the color of peanut butter (the same color as chestnuts).
  • Python - A giant Earth Dragon who was an old enemy of Apollo. In The Blood of Olympus, Python was revived by Gaea during the Second Gigantomachy and it was mentioned that Python reclaiming Delphi was one of Apollo's many failures. In The Hidden Oracle, Apollo and Meg McCaffrey are in the Labyrinth where they overhear Python talking to Nero about the plans to control all the Oracles.
  • Pit Scorpion – A deadly type of scorpion that appears in "The Lightning Thief." When Luke brings Percy into the woods and reveals his allegiance to Kronos, he summoned a Pit Scorpion to attack Percy. He tells Percy he should not go for his sword, as the pit scorpion can kill in sixty seconds, and can jump up to fifteen feet. When Luke disappears, Percy manages to kill it even though it managed to sting him. Wood nymphs help Percy recover from its poison.
  • Scylla – One of the two monsters (the other being Charybdis) who live on either side of a narrow channel of water in The Sea of Monsters. Should a ship sail too close to her, she uses her six heads to pluck off crew members on deck and devour them. According to Clarisse (daughter of Ares), Scylla would just pick up the whole boat and crushed the boat if the crew hid below deck. In the film Percy Jackson: Sea of Monsters, Scylla was mentioned by Clarisse to have eaten Ichneutae.
  • Sea Serpent – A large serpent that lives in the sea. Deimos is seen riding one in "The Stolen Chariot." In "The Last Olympian," a sea serpent was seen amongst the sea monsters in Oceanus' army.
  • Sirens – The Sirens are dangerous bird women whose sweet songs lead many sailors to their deaths on the jagged rocks. In The Sea of Monsters, they almost killed Annabeth.[7]
  • Skeleton – Skeletons are the undead troops that make up Hades' Undead Army. In "The Lightning Thief," Hades has skeletons in army uniforms guarding his palace. In "The Battle of the Labyrinth," Nico manages to employ them as part of a ritual that will enable him to call the spirit of his sister to speak with her. In "The Last Olympian," Nico and Hades manage to bring a troop of skeletons to help fight the Titans. They are later seen constructing a cabin at Camp Half-Blood which is dedicated to Hades. In the House of Hades they are on the demigods side and help them in the Hades's temple in Epirus.
  • Skolopendra – A sea monster that is 200 ft. long. It looks like a cross between a giant shrimp and a cockroach with a pink chitinous shell, a flat crayfish tail and millipede-type legs. Its face is a slimpy pink like an enormous catfish with two glassy dead eyes and a gaping toothless maw. It has a beard which has a numerous amount of tentacles sprouting from each nostril. In The Mark of Athena, Ceto sents Skolopendra after the demigods after their escape from Phorcys' aquarium. It attacked the Argo II when Leo forgot to turn the monster-detection system on. Percy describes Skolopendra as "shrimpzilla." Skolopendra withdraws into the ocean when Leo Valdez and Hazel Levesque throw test tubes filled with Greek Fire into its mouth.
  • Spartus – A troop of skeletons armed with weapons. They are usually summoned by planting dragon (Sybaris) teeth in the ground and watering them with blood. In The Titan's Curse, some Spartoi ambushed Percy, Thalia, Zoe, Grover and Bianca in New Mexico. Due to her being a child of Hades, Bianca managed to destroy them. In The Son of Neptune, Frank (as a gift from his father) is given a spear with the tip of a dragon's tooth that when planted with raise one of the Spartoi, he uses this to defeat the basilisks outside of the R.O.F.L. headquarters, to kill some of the laistrygonians surrounding his grandmothers house then using his final charge to protect the mortals on a train from attacking Griffins.
    • Gray - A Spartus that can be summoned by Frank Zhang.
  • Sphinx – A Sphinx is a monster with the head of a woman and the body of a lion. Percy Jackson and his friends encountered the Sphinx while navigating the labyrinth. Rather than tell riddles, the Sphinx asked historical questions which Annabeth refused to answer as an insult to her intelligence. They are not to be confused with the Sphinx from The Kane Chronicles.
  • Stymphalian Birds – A flock of birds once attacked Camp Half-Blood in The Sea of Monsters. Percy and Annabeth used Chiron's music to scare them so Apollo's cabin could shoot them down. A flock of Stymphalian Birds attack the Argo 2 in "The House of Hades."
  • Telekhine – The Telekhines are a race of dog-faced sea demons that reforged Kronos's blade in the fourth book. Some set Percy on fire in the fourth book. They also appear in the fifth book. In the fourth book, they are referred to as "telekhines." However, in the fifth book, they are referred to as "telkhines", without the second "e". This may be a typographical error or something different of the author's choice. In The Mark of Athena, some Telekhines are seen in a water tank at the Georgia Aquarium.
  • Trojan Sea Monster – A type of sea monster that rampaged the coasts of Troy until it was slain by Heracles. It is also known as the Keto Trois. In The Lost Hero, Jason Grace claims to have slew this monster while fighting Porphyrion of the Gigantes.
  • Typhon – A very powerful monster. He sired many monsters by Echidna. He lives and sleeps inside Mount Saint Helens. Percy is such a powerful demigod that he almost wakes Typhon during his visit there. In The Last Olympian, Typhon awakes and moves across America destroying everything in his path. As he is concealed in mist, Typhoon's appearance is not described and appears as a freak storm. The gods of Olympus try to stop him, but he is too powerful. In the end, Poseidon and his army help defeat him where Poseidon opened up a tunnel that sends Typhon into Tartarus. Once Typhon was defeated, a wave of anemoi thuellai were born.[10]
  • Unicorn – A horse with one horn. A herd of Unicorns are used as steeds for the campers of Camp Jupiter. A red-tinted Lares with the head of a wolf guards them.
  • Venti – A race of storm spirits that were born when Poseidon opened a tunnel that sent Typhon into Tartarus. Depending on how chaotic they are, Venti can appear as either smokey men with angel-like wings or smokey horses. In The Lost Hero, Aeolus sent the Venti to prevent Jason, Piper, Leo, and the Hunters of Artemis from rescuing Hera. Their Greek counterparts are anemoi thuellai.
    • Dylan – A ventus that was among the Venti that attacked Jason Grace, Piper McLean, and Leo Valdez as seen in The Lost Hero.
    • Tempest – A ventus in smokey horse form that appears in The Lost Hero. Jason tames Tempest so that it can help him fight Porphyrion.

The Kane Chronicles

Main characters

Carter Kane

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

Carter Kane is one of two main protagonists and narrators; a descendant of Narmer and of Ramses the Great. He is the son of Julius and Ruby Kane. After the death of his mother (when he was eight years old), he spent six years travelling the world with his Egyptologist father. After his father is captured by the god Set during The Red Pyramid, Carter spends most of his time with his sister Sadie and uncle Amos Kane. He becomes the host of Horus in the first novel, and often collaborates with and receives advice from the god. He also develops a romantic relationship with the shabti of magician Zia Rashid, and subsequently spends much of his time trying to find the real Zia and demonstrate his feelings toward her. Like his father, Carter has dark skin and hair, quite different from both his mother and sister. When living with his father, Carter dressed "impeccably" like Julius even when relaxing, but adopts a much more casual style when he goes to live at Brooklyn House. Though he is not one to flout rules, Carter is brave and courageous enough to pursue the way of the gods despite the House of Life's disapproval. His specialty is combat magic; his preferred weapon a khopesh. He is often given leadership responsibilities and struggles to accept his role, until he willingly becomes pharaoh of the House of Life during The Serpent's Shadow.

Sadie Kane

Sadie Kane is one of two main protagonists and narrators; the younger sister of Carter Kane. She is left in the care of her non-magical grandparents in London after the death of their mother Ruby Kane. Though she is able to live a "normal" life, something her brother is occasionally jealous of, her unusual circumstances make her sometimes jealous of Carter (especially when she is reminded of his exotic lifestyle). Sadie has to abruptly leave her life in London when she goes to revive the twenty-first Nome and fight Set after the god captures her father, Julius Kane. Sadie becomes the host of Isis in The Red Pyramid and continues to study the goddess's path throughout the series. She also becomes romantically involved with one of the Brooklyn House initiates Walt Stone and also with the god Anubis, though her relationship with either is not formalized until after Walt becomes the "eye" of Anubis in The Serpent's Shadow.

She has caramel-colored hair and light skin, traits inherited from her mother Ruby. Unlike Carter, Sadie is rebellious and bold (also like her mother) and acts the part; often making snap decisions, ignoring rules, and choosing to wear clothing to display her personality rather than to conform or aid her magic. Her magical specialty is with spells, potions, and hieroglyphics.

Walt Stone

Walt Stone is one of the twenty-first Nome's initiates, who arrives at Brooklyn House sometime between the first and second novels. He has dark skin and is from Seattle, where he lived with his mother. Walt is a sau, or charmmaker.[18] In The Throne of Fire, it is revealed that Walt has inherited a deadly curse from his ancestor Akhenaten, which will kill him before reaches adulthood, as it did to his father and their famous ancestor King Tut. The curse progresses more quickly when he uses magic, which is why he specializes in charms and also why he begins to call on the god Anubis for guidance. In The Serpent's Shadow, Walt finally succumbs to the curse, but as he dies he allows himself to become the host of Anubis, whose spirit can essentially keep him alive. Both Anubis and Walt Stone have romantic feelings for Sadie Kane, and this is part of the reason why the two "fuse" successfully.

Zia Rashid

Zia Rashid is a magician from the first Nome who was born and raised in Egypt. She is found and raised by Iskandar, the Chief Lector, after the destruction of her hometown by Apophis. When Julius Kane released five gods through the Rosetta Stone, she became the unexpected host of Nephthys, and was subsequently placed by Iskandar in an underwater prison so the House of Life could not eliminate her. A shabti of her was created to take her place; it is destroyed during the fight with Set in The Red Pyramid. Carter Kane falls in love with this shabti and seeks out the real Zia to free her and release Nephthys's spirit. Zia, who specializes in fire magic, later becomes the host of Ra and the two manage to destroy Apophis in The Serpent's Shadow. Her initial indifference to Carter slowly evolves into romance, and the two begin dating at the end of the series when Ra ascends back to the heavens.

Amos Kane

Amos Kane is Julius Kane's younger brother, Carter and Sadie's uncle, and the leader of the twenty-first Nome (New York). He takes in Carter and Sadie after Julius hosts Osiris and is trapped by the god Set. During the first novel, Amos is possessed by Set and forced to lure his niece and nephew to the god's pyramid in Phoenix, Arizona. Once freed, Amos goes for healing at the first Nome, and does not return to Brooklyn House until the second novel. His experience hosting Set has changed him, however, and eventually leads to his highly-controversial decision to voluntarily host the god during the final battle with Apophis. Amos succeeds Michel Desjardins when the former leader of the House of Life sacrifices himself fighting Apophis.

Iskandar

Iskandar is the Chief Lector of the House of Life. Born in the 1st century BCE, during the reign of Cleopatra VII, he witnessed the end of the Egyptian monarchy and the absorption of Egypt into the Roman Empire. He came to believe this was the fault of the gods and ended the House's policy of calling upon them; Ruby Kane's vision of Apophis rising changes his mind, but it is too late for him to make any real change. He was the one who saved Zia after her village's destruction and, sensing that she holds the power to host Ra, arranged for her confinement in an underwater prison under the watch of Nephthys while creating a shabti of her to protect Carter and Sadie, both of whom also hold the potential to become hosts of gods. Shortly after meeting them, he dies in his sleep, knowing that these three can make a change where he could not. He is succeeded by Michel Desjardins as the House's leader.

Michel Desjardins

Michel Desjardins is the lesser antagonist and leader of the House of Life after the death of Iskandar. Desjardins is approximately 200 years old, considered "young" for a magician, and as such has known only the House policy of exterminating the gods. He is therefore at first opposed to cooperation with the gods. He works with Vladimir Menshikov in the latter's attempt to hunt Sadie and Carter Kane, but he chooses to sacrifice himself execrating Apophis when he learns of the chaos serpent's rising and Menshikov's attempt at a form of mind control. He is succeeded as leader of the House of Life by Amos Kane.

Egyptian deities

  • Anubis — God of funerals and death and periodic advisor to Sadie Kane, for whom he has romantic feelings. Walt Stone becomes his host in The Serpent's Shadow. Anubis is the son of Nephthys and Set, but felt closest to his uncle Osiris, who raised him in Duat.
  • Apophis — The serpent of chaos who fought Ra in ancient times. Throughout the series, he possesses demons and other characters in attempts to break free of his prison (a place deep within the Duat where he once battled Bast for eternity). He breaks free of his prison in The Throne of Fire, but is execrated by Michel Desjardins. He does so once again in The Serpent's Shadow, but is held at bay through the combined efforts of many gods and magicians.
  • Babi — Egyptian baboon god who takes Mr. Faust as host, helping Nekhbet test Sadie Kane.
  • Bast - The cat goddess and Ra's guardian. In ancient times, she was sent by Ra to fight Apophis after the latter ascended to the heavens, which she continues to do until Julius and Ruby Kane release her. She then takes as host a cat named "Muffin" and makes a pact to guard Sadie. Bast then becomes Carter and Sadie's guardian after the two become magicians, and becomes quite close to them, considering them her "kittens". In The Red Pyramid, she sacrifices herself fighting Sobek to protect the injured Sadie, but is brought back from Duat by the gods as reward for the Kanes (after they defeat Set).
  • Bes — God of dwarfs and protector of the innocent. He has romantic feelings for Bast, and answers her request that he watch over Carter and Sadie. He befriends the two and sacrifices his ren to give them enough time to reach Apophis's prison. The two later manage to restore him, and he goes on to pursue a relationship with the goddess Tawaret.
  • Geb — God of the earth. Father of Osiris, Isis, Horus, Set, and Nephthys; husband of Nut. His physical manifestation is the entire earth.
  • Hapi — God of the Nile river. In The Serpent's Shadow, he is summoned by Carter using a spell from Setne, and asked to defeat a monster sent by Apophis. Hapi also helps Carter and Zia cross the Nile to reach the temple of the Apis Bull. Hapi is described as huge, blue-skinned, and well-fed.
  • Heket — An ancient goddess of frogs who lost her power when her temples were destroyed and people stopped worshiping her. She is currently living in Sunny Acres Assisted-Living Community, a place for senile gods and goddesses, as revealed in The Throne of Fire.
  • Horus — God of war; Leader of the gods until Ra's return, and again after Apophis is destroyed. Part of his spirit resides in Carter Kane. His symbol is the Eye of Horus. He is one of the five gods born during the Demon Days (the five days at the end of the solar calendar that account for its not being an even 360 days long), the son of Geb and Nut. He is also frequently described as the son of Osiris and Isis.
  • Isis — Goddess of magic; briefly incarnated by Sadie and Ruby Kane; her symbol is the Tyet. She is one of the five children of Geb and Nut, and the mother of Horus. She is responsible for Ra's ascendance from the mortal world. When she wanted her husband Osiris to claim Ra's throne, she created a serpent to poison Ra. When he revealed to her his secret name, she cured him but also forced him to abdicate the throne.
  • Khonsu — Moon god. He was a trickster who liked to play senet, a board game, with deadly bet in return for a lengthened time; Nut once played a game with him so she could gain enough time to give birth to her five children. In The Throne of Fire, the Kanes and Bes played senet with him so they could gain more time for the gates of Duat to open; when they lose a round, Bes sacrificed his ren, which caused him to lose his memories until the Kanes managed to find his sheut in The Serpent's Shadow.
  • Mekhit and Onuris — Two war gods who were forgotten by humans and thus had to live in Sunny Acres. Onuris disappeared due to his senility, which made Mekhit mournful. He is found again in The Serpent's Shadow, and later fights alongside his wife with the retired gods who helped the Kanes.
  • Neith - Goddess of the Hunt. She loves weaving. She makes a brief appearance in The Serpent's Shadow when Sadie and Walt trick her into helping them.
  • Nekhbet — Egyptian vulture goddess who takes Mrs. Faust and Percy Jackson as hosts. She is a follower of Ra, but refuses to follow the weak. As a result, she "tests" Sadie Kane's strength by attempting to kill her, her family, and her friends. It is revealed in The Crown of Ptolemy that Nekhbet possesses the crown of Upper Egypt, which Setne steals, although she manages to avoid Wadjet's fate of having her essence absorbed thanks to the heroes. She proceeds to assist them in order to recover her crown.
  • Nephthys — Goddess of rivers; wife of Set, mother of Anubis, and one of the five children of Geb and Nut. She was once incarnated by Zia.
  • Nut — Ancient Egyptian sky goddess; mother of Osiris, Isis, Horus, Set, and Nephthys. Wife of Geb. Due to a prophecy that one of her children would unseat him, Ra forbade Nut to give birth on any day of the year. She gambled with the god Khonsu to earn five extra days worth of moonlight to have her children and was punished by Ra. He forbade her to ever see her husband again, and tasked her father Shu with keeping them apart. Her physical manifestation is the sky itself.
  • Osiris — Ancient Egyptian god of the dead; incarnated in The Red Pyramid by Julius Kane. He is one of Geb and Nut's five children. His symbol is the 'Spine of Osiris', or the djed. He is frequently described as having blue skin, representing the fact that he is "dead". He was once king of the gods until his brother Set imprisoned and later killed him. His wife Isis and sister Nepthys searched for his body to revive him with magic, but were only able to make him pharaoh of the Duat.
  • Ptah — God of craftsmen and creation, summoned by Sadie and Walt help get a piece of the Book of Ra.
  • Ra — Sun god. Retired to the heavens, but revived in The Throne of Fire; later merges with Zia and recovers his lost mental integrity. Consumed by Apophis and later revived by Sadie and Carter. He was the first and greatest king of the gods, and undertook nightly journeys through the Duat (as the sun sets and rises) to battle the forces of chaos.
    • Khnum — Ra's evening aspect who created man out of clay using a potter's wheel. In The Throne of Fire, the Kanes meet him near the entrance of the Duat and have one chance to guess his name, which he had forgotten after so long. Sadie eventually gave him his ren, which was what he was really looking for, and he allows them to pass on to revive his other aspects.
    • Khepri — Ra's morning aspect that had the form of a golden beetle. The Kanes found it near the exit of Duat and had to battle Valdimir Menshikov, possessed by Apophis, in order to give it to Ra and thereby restore his final aspect.
  • Set — Ancient Egyptian god of evil. Antagonist of The Red Pyramid, and a supporting character in The Throne of Fire and The Serpent's Shadow. He is one of Geb and Nut's five children, born on the last Demon Day, and is married to Nephthys. He was once Ra's "faithful lieutenant" against the forces of Isfet, but became the embodiment of chaos after Ra's ascension. His secret name is 'Evil Day'.
  • Sekhmet — Goddess of lions. She can be summoned by a Chief Lector once in his/her lifetime, and attacks Carter, Sadie, Zia, and Amos at the command of Michel Desjardins. She is the warlike lieutenant of Ra and a master of destruction.
    • Hathor — Goddess of cows, also the alter-ego of Sekhmet. She is summoned whenever Sekhmet is tired, and represents the goddess's peaceful side.
  • Serqet — Goddess of scorpions. In The Red Pyramid, she attacked Carter, Sadie, and Bast after the three had escaped from Brooklyn House, forcing Bast to retreat while the Kanes were saved by Zia.
  • Shezmu — God of execution. In The Red Pyramid, he prevented the Kanes from entering Duat unless they told him his secret name, though he ended up revealing it to Sadie while the three compromised.
  • Shu — God of the Air; The father of Nut and Geb, who separates Nut from Geb to form the present-day division of Sky from Earth. Later appears to criticise Anubis' infatuation with Sadie.
  • Sobek — God of crocodiles; appears as a minor antagonist in The Red Pyramid but later aids Ra against Apophis.
  • Tawaret — Egyptian goddess of hippos and childbirth, assists the protagonists. As a protector of the innocent (specifically children), like the god Bes, she is very familiar with him and has romantic feelings for him. At first these are unreciprocated as he is in love with Bast, but he comes to appreciate and care for her after she takes care of him when he has lost his ren. Tawaret is the sole nurse in the Sunny Acres retirement community for old gods, located in the Duat.
  • Thoth — God of knowledge; founder of the House of Life. "Thoth" was actually his Greek name; Egyptians called him Djehuti. He is the only god who is accepted by the House of Life and is allowed to inhabit the mortal world; he is found in Memphis, Tennessee in various locations. Carter and Sadie seek him out for advice on two separate occasions.
  • Wadjet - A cobra goddess who makes a brief appearance in The Crown of Ptolemy where Setne summons her, steals her crown of Lower Egypt, and then steals her essence, killing her.

Magicians

Brooklyn House trainees

  • Jasmine 'Jaz' Anderson — One of the novitiate magicians in Brooklyn House. She is a blonde, sixteen year-old cheerleader from Nashville, Tennessee. Her specialty is healing magic and studies the goddess Sekhmet as all Egyptian healers do. She is put into a coma after banishing some sickness demons in The Throne of Fire, from which she is awakened by Ra. She shares with Sadie how to cure Carter using his ren when he is bitten by a tjesu heru.[19] She later appears in The Serpent's Shadow and her healing potions appear in the crossover stories The Son of Sobek and The Staff of Serapis.
  • Alyssa - A trainee of the twenty-first Nome with a particular skill for pottery and shabti-making. She studies the power of Geb.
  • Cleo - One of the young magicians at Brooklyn House. She is from Rio de Janeiro. Cleo studies the god Thoth and will likely be Brooklyn House's next librarian. Though she is an excellent researcher, she does not have much of a stomach for violence.
  • Felix - A 10-year old trainee at Brooklyn House. He has a strange obsession with penguins and seems to be able to channel ice magic, though it is unknown which Egyptian god this corresponds to.
  • Julian — A seventh-grade trainee. Like Carter, he incarnates the power of Horus.
  • Sean - An Irish trainee at Brooklyn House.
  • Shelby - A very young trainee at Brooklyn House, the ringleader of the group of toddler trainees known as the "anklebiters". Her magic is mostly impulsive.
  • Leonid - A young Russian magician who first encountered the Kanes when they visited Saint Petersburg. He defects to the "side" of the gods and, with the help of the god Shu, brings Sadie and Carter information during book three.

Other magicians

  • Julius Kane — Carter and Sadie's father, and a doctor of Egyptology. After a failed attempt to release the Egyptian goddess Bast back into the world results in the death of his wife, he works to find a way to release them again and become host to Osiris. He ultimately succeeds, dies of his own free will, and goes to "live" as the god's physical manifestation in the Underworld, overseeing the Hall of Judgment.
  • Ruby Kane — Carter and Sadie's late mother, who appears occasionally as a ba to advise her children. She was a magician and diviner who foresaw Apophis's rise and ultimate victory if the other gods were not there to stop him. As a result, she and her husband attempted to release Bast from her eternal battle with Apophis so the goddess could heal before his inevitable rise. She gave her life to close the portal they opened using Cleopatra's Needle, because Apophis was fighting to get out. Ruby also communed with Isis at some point in her career as a magician, and attempted to convince then-Chief Lector Iskandar to remand his policy of fighting the gods.
  • Vladimir Menshikov — The antagonist of The Throne of Fire. Menshikov's intense hatred of the gods and desire for power leads to his possession by Apophis. He manipulates Michel Desjardins into permitting him to hunt the Kane family. When Desjardins finally discovers his involvement, he uses up all his energy in an execration of the chaos demon and, by extension, Menshikov, who is then killed. Menshikov is described by Sadie and Carter Kane as an "evil ice cream man"[18] because of his tendency to wear white suits and glasses because of his heavily scarred face.
  • Setne - An evil magician and son of Ramses the Great. He is also known as Khaemwaset. He appears in The Serpent's Shadow as an evil ghost on trial for many crimes. Setne is freed by the protagonists Carter and Sadie to aid in the fight against Apophis. After the former's destruction, however, Setne escapes and becomes the main antagonist of the crossover series with the Camp Half-Blood chronicles, where he plans to amass the power of both the Egyptian and Greco-Roman worlds. He is finally trapped in a snow globe by Carter, Sadie, Percy Jackson, and Annabeth Chase.
  • Sarah Jacobi - The leader of a group of rebel magicians, a former House scribe imprisoned for causing the 2004 Indian Ocean earthquake and tsunami. In The Serpent's Shadow, she manages to amass an alliance of rebels in league with Apophis, but is vanquished by Anubis/Walt Stone, who bury her underground.
  • Kwai - Sarah Jacobi's assistant, the House of Life's persistent opponent throughout the later books and also a brief host of Apophis.

Egyptian creatures

  • Ammit the Devourer — A part-hippo, part-crocodile, part-lion demon who devoured souls that were judged unworthy in the Halls of Judgment. The Kane Chronicles present a different picture of Ammit than is typical, by portraying the demon as both no larger that a toy poodle and as a male. In Egyptian myth, Ammit was both female and an enormous fearsome monster. In The Throne of Fire, "he" is nicknamed "Poochiekins" by Sadie.
  • Doughboy — Julius Kane's wax shabti; comically resentful of Julius. He is used for many purposes by Carter and Sadie.
  • Freak - Carter's pet griffin. It was initially a statue brought to life by Sadie. Tamed by Carter in The Throne of Fire (because the griffin is a sacred animal of Horus); his pet and personal transportation thereafter.
  • Khufu — Amos's pet baboon. Like many baboons in the series, he loves basketball and speaks only in monosyllabic grunts. Khufu's other quirk is that he only eats things that end in the letter 'O', such as Cheerios, Jell-O, and flamingo meat.
  • Leroy - The Set animal that was destroyed and nicknamed by Carter Kane.
  • Mummy - The Mummies are undead bodies that are wrapped in bandages. They can be summoned through Egyptian necromancy.
  • Philip of Macedonia — Amos's albino crocodile pet, later identified as a wax shabti. Protector of and (briefly) transporter for the protagonists.
  • Serpopard - The Serpopard is a controlled creature of chaos that has the head and neck of a snake and the body of an African leopard. They have the ability to spit poison and are tremendously strong.

Magnus Chase and the Gods of Asgard

Main characters

Magnus Chase

Magnus Chase is the main protagonist of the series. A 16-year-old Bostonian teenager, Magnus lost his mother Natalie to a mysterious wolf attack two years prior to the events of The Sword of Summer and is forced to live in the streets with his homeless friends, Blitz and Hearth. On his 16th birthday, his uncle, Randolph informs him of his divine parentage as a son of a Norse god and his inheritance of Sumarbrander, the sword that once belonged to his father. After being killed by Surt, a fire giant, Magnus is then sent to Hotel Valhalla by Sam, a Valkyrie. He then finds out that his father is Frey, the god of peace and prosperity, who belongs to the Vanir tribe of Norse deities.

Magnus is described as having parted blond hair that reaches his chin and haunting gray eyes that resemble his cousin's, Annabeth. He is said to look like Kurt Cobain and has asthma. His scrawny look is replaced by a more muscular persona after his death and acceptance to Valhalla. He is quite street smart due to the two years he spent as a homeless man and as a result, is not quick to trust people. Nevertheless, he considers Blitz and Hearth as the only friends he is completely loyal to, and after a while, also begins to ease up and trust Sam.

Blitzen

Blitzen (Blitz) is a 20-year-old dwarf or, more specifically, a svartalf from Nidavellir. He has dark skin and hair, and has a beard. He is the son of a Vanir, Freya, making him Magnus' cousin, and a dwarf, Bilì, who was eaten by Fenris Wolf while checking Fenris's prison rope. He is sent alongside Hearth by Mimir to watch and protect Magnus. Though he keeps it up for two years, the task fails when Magnus is killed, but Blitz continues to look for him until they are reunited in Valhalla. As a dwarf, Blitz is sensitive to sunlight and will slowly turn to stone if exposed too much, which is why he always wear a copious article of clothing whenever there is sunlight, except in Folkvanger, in which sunlight is replaced by an aura radiated by Freya instead. Instead of forging, Blitz excels in clothing design, making him a laughing stock among his fellow dwarfs, but after he wins a match against Eitri Junior, he becomes respected and eventually opens up a clothing shop. Blitz has had a strong relationship with Hearth ever since the former saved the latter's life, and the two are very protective of each other.

Hearthstone

Hearthstone (Hearth) is a light elf from Alfheim. He is skinny with fair skin and with short spiky white hair, which, when combined with his black leather jacket, jeans and a red scarf, "makes him look like a character from a Japanese anime". Hearth is deaf and can only communicate with ASL (Alf Sign Language), though he is able to read lips. Since his home world is always bright, he is sensitive to darkness. Like Blitz, Hearth makes a deal with Mimir to drink water from Mimir's Well by one of the roots of Yggdrasil to gain knowledge about runes and in return has to work with him for several years. He becomes a companion and protector of Magnus from then on. Hearth is the first elf in a long time to focus on magic from runes, which he has studied extensively. He can cast various runes, though doing such consumes his energy. Eventually he progresses to the rank of a full sorcerer. Hearth has a traumatic past, as he is effectively unwanted by his parents, who shun him for being deaf and not as great as his brother, who died young. His relationship with his friends helps him, though, and he even once calls Magnus "brother". At the end of the first book, Hearth is freed from servitude and begins learning runes at Asgard.

Samirah al-Abbas

Samirah (Sam) al-Abbas is a Valkyrie and a daughter of Loki who selects Magnus as an einherji under Odin's order. She is an Arab American who normally wears her Valkyrie armory and a noticeable green hijab, which also functions as a swan cloak, or an invisibility cloak. As a Valkyrie, Sam is different from Magnus in that she is still alive. She leads a double life as both a Valkyrie and a normal high school student. She does not worship the Norse gods as she already has a God she believes in, though she still has to occasionally work with them. Her family is from Baghdad, Iraq, and Sam is raised by her grandparents after the death of her mother Ayesha. Sam's family already had a long history with the Vikings, even before her mother met Loki; Ahmad ibn Fadlan, an envoy of the Abbasid Caliph to the Kievan Rus', is one of Sam's ancestors, and the Varangians had since intermarried with Sam's family. Her parentage is a shame to both sides of her parents; she is shamed in her mother's family as an out-of-wedlock child, while having Loki as a father makes others view her as suspicious among the Asgardians. Sam is expelled from Valhalla when her video of Magnus' heroic death is edited by Gunilla, but later joins Magnus, Blitz, and Hearth in stopping Fenris Wolf from breaking free. She eventually gets another job as Odin's personal aide and Valykrie. Sam has an interest in flying and planes and vows to become a pilot one day, which is why she is very serious about her job as a Valkyrie.

As a fighter, Sam excels in using the axe, a weapon of the valkyries. She also inherits her father's ability to shapeshift into animals such as a horsefly or lion (her surname, al-Abbas,means 'of the Lion' in Arabic); however, it makes her uncomfortable, as it causes her to become more like her father, Loki.

Sumarbrander

The Sword of Summer (Jack) was Frey's weapon, currently wielded by Magnus Chase. After Magnus finds out that the sword is sentient, Sumarbrander decides to name itself Jack, and be referred to as a male. In battle Magnus can let the sword attack his enemies on its own or use his own strength and control the sword himself. Either way, it is Magnus who loses energy ultimately, though this loss is delayed until he next grips or sheathes Jack.

He bears a grudge against Frey, who 'abandoned' him, by giving him to Skirnir as a price for the latter bringing the former a Giantess with whom he fell in love; he summarises this by once admonishing Frey, saying 'blades before babes'.

He reached Boston with one of Skirnir's descendants during the Viking expansion, where he was lost for centuries till he was recovered by Magnus

Norse deities

The Norse gods fall into two general groups: the Aesir and the Vanir. All are referred to generally as "Asgardians", but the Vanir inhabit Vanaheim as often as Asgard. The Aesir are more warlike, while the Vanir are peaceful. Specifically, however, the gods tend to be distinguished by what side they fought on during the Aesir-vanir war, and not by their personal temperaments.

Aesir

The following Norse gods are considered the more warlike of the two strains of immortals.

  • Loki – Loki is the god of evil and trickery. He is the adoptive son of Odin, brother of Thor and father of demigod Samirah Al Abbas. After tricking Hod to kill Balder, he is chained to a rock with the entrails of his sons as chains with poison from a snake dripping onto his face constantly. His three children, Fenris Wolf, Jormungand, and Hel, are destined to be three of the main contributors to Ragnarok. Loki appears to Magnus in dreams, wearing a Red Sox shirt, and tries to persuade him to give Sumarbrander to his uncle, Randolph. He ultimately fails, fulfilling the first part of the prophecy of the Norns, and at the end of the book is revealed to be working with Randolph.
  • Mimir – Mimir is the god of knowledge and wisdom. He was beheaded during the Æsir-Vanir War and only his head remains. He is the boss of Blitz and Hearth due to a deal they made, in order to drink from his well. The deal is nullified by Odin at the end of first book as their reward for dealing with Fenris Wolf.
  • Odin – Odin, the "All-Father", is the king of the Aesir, the god of royalty and magic. He is able to rewrite reality by spelling out runes, which he learned after hanging for nine days on a branch of Yggdrasil. In The Sword of Summer, Odin is claimed to have disappeared two years before Magnus' acceptance as an einherji, but he actually disguises himself as X, the son of a troll, and one of Magnus' floormates. At the end of the book, Odin reveals himself and rewards Magnus and his friends for their bravery against Fenris Wolf. He likes to give presentations.
  • Ran – Ran is the goddess of the sea, who operates a net that collects anything that falls into the sea, including tools, trash, and souls. She has an apple of Idun, but forgets to consume it, which contributes to her elderly appearance. Magnus and Sam manage to convince her to give them the apple and Sumarbrander, but she warns that doing so has made her and Aegir bent on attacking Magnus.
  • Thor – Thor is the god of lightning, storms, and strength. He has an unkempt appearance, is lazy, and is also up-to-date with modern television shows. He has red hair, huge muscles and a dirty face. He wears a sleeveless, leather jerkin and is very loud. He tasks Magnus and his friends with retrieving his spear, which was stolen from him by Geirrod. He has two talking goats, Tanngrisnir and Tanngnjóstr, nicknamed Otis and Marvin. His hammer is currently missing.

Vanir

  • Freya – Freya is the goddess of love and warmth and the twin sister of Frey. She is described as very beautiful. She presides over Vanaheim, where the other half of worthy souls go after death, and casts warmth that shines over it. Freya is the mother of most dwarves in Nidavellir, including Blitz, which happened because she bartered to (briefly) marry some dwarves in exchange for luxurious items. Freya tasks Blitz to get some earrings by challenging Junior.
  • Frey – Frey is the god of fertility, warmth, and healing, the twin brother of Freya, and the father of Magnus. Frey owned a sword, Sumarbrander, which was given to Skirnir in return for his help in wooing a beautiful giantess; as a result, he is unarmed by the time of Ragnarok and will be killed by Surt. Though Magnus never meets his father until the end of the first book, he realizes that all the times his mother took him hiking through the wilderness was a way for them to get closer to Frey.

Other Norse gods

  • Hel – Hel is the daughter of Loki who presides over Helheim, the realm where the unworthy dead go. One half of her is a very beautiful woman, while the other is a decaying corpse. She tries to persuade Magnus to give up Sumarbrander to Randolph, but he refuses.
  • Norns – The Norns are a trio of female figures who can see the past, present, and future. They recite a prophecy to Magnus that kickstarts his journey to stop Fenris Wolf from breaking free.

He almost dies at the end of The Sword of Summer, but is revived by Magnus' power of healing.
  • Hunding – Hunding is the bellhop of Hotel Valhalla and is Helgi's servant because years ago, they were opponents on the battlefield, and when they came to Valhalla, Helgi was made the manager. His first order was to have Hunding do all the menial labor. Hunding has been at the hotel for thousands of years and longs for his family.
  • Lars Alhstrom – Lars Alhstrom is an einherji and son of Thor who comes to Hotel Valhalla alongside Magnus.
  • Mallory Keen – Mallory Keen is an Irish einherji. She is foul-mouthed and quick to criticize someone, though T.J. explains that those are her expressions of affection.

Magnus notes that Mallory does not react as violently as she normally would to Halfborn placing his arms around her at the end of the book.
  • Thomas Jefferson Jr./TJ – Thomas Jefferson Jr., or TJ for short, is an einherji from the 1800s....specifically, the American Civil War. He is a son of Tyr and a runaway slave.

  • X – X is a half-troll and one of Sam's more controversial choices. His skin is grey and covered with warts and welts. He is called X, as his real name is unpronounceable. He died in Chicago, breaking up a dog fighting ring. At the end of the book, it is revealed that X is actually Odin in disguise.

Valkyries

  • Gunilla – Gunilla, nicknamed "Gorilla" by Magnus, is a daughter of Thor and the leader of the valkyrie. She is spiteful towards Sam, because Sam is a daughter of Loki. She once dated a son of Loki who turned out to be a spy of his father.

She later sacrifices herself while fighting Surt while Magnus re-impriosns Fenris Wolf. She carries a bandolier of hammers.

  • Fenris Wolf – Fenris Wolf is the lupine son of Loki and the brother of Hel and Jormungand. He was a terror in times past and the gods could only chain him up with the help of the dwarves to stop him; even Tyr had to lose his hand against the wolf, while Blitz's father, Bilì, lost his life while checking his prison on Heather Island. During Ragnarok, Fenris Wolf is destined to kill Odin and eat the sun. He is the focal point of The Sword of Summer, as the goal of Magnus and his friends is to stop Fenris Wolf from breaking free of his prison, which needs to be rebuilt. They manage to imprison him again at the end of the book.
  • Heidrun – Heidrun is a goat whose milk is the source of the mead that serves the gods. Like Eikthrymir, Heidrun resides in Hotel Valhalla.
  • Jormungand – Jormungand is the serpentine son of Loki. He is a snake who circles over Midgard and is so long he must hold his tail in his mouth to prevent destroying Midgard. He is lured by Magnus and Sam to cause a ruckus in the sea big enough to summon Ran. Even after being lured, Jormungand is still half-asleep, but Ran warns that waking him up completely would cause Ragnarok, where he is destined to kill Thor.
  • Jötunn - The Jötunn (also known as Jotnar) are the Norse Giants of which there are many types. In the first novel, mountain giants, frost giants, and fire giants are all encountered and referred to generally as "jotunn". While some jotunn are mortal, some are not.
    • Geirrod – Geirrod is a Giant who owns an anti-geometry house in Jotunheim. He keeps a weapon of Thor, which is mistaken by the others for his hammer. Geirrod is killed when Magnus and his friends kick the pillars of his house down while he is drunk.

    • Harald – Harald is a Frost Giant who operates a boat in the port of Boston. He helps Magnus and Sam set a bait for Jormungand in order to summon Ran. He is easily swayed by red gold, which can bribe him to do almost anything.
    • Surt – Surt is the king of the Fire Giants of Muspellheim. He is destined to kill Frey using Sumarbrander and burn Nine Worlds during Ragnarok. Though he manages to kill Magnus, Surt's nose is cut and does not recover by the time of his second encounter with Magnus, where he is expelled back to Muspellheim.
    • Utgard-Loki – Utgard-Loki is a Mountain Giant the King of Jotunheim. He is sometimes mistaken for the more famous Loki, which he hates. As an eagle, Utgard-Loki forces Magnus to retrieve an apple of Idun for him, which reverts him back to his youthful state.

It is also tasked to capture intruders who enter and leave Hotel Valhalla without permission. Ratatosk is able to emit sorrowful callings to people, which Magnus describes as much worse than simply being gnawed by it.
  • Saehrimnir – Saehrimnir is a creature whom the Aesir and einherjar kill every night for food only for it to rematerialize the next morning. Its flesh's taste depends on what its eater wants it to taste like.

Junior is more than 500 years old.
    • Nabbi – Nabbi is a bartender of a bar in Nidavellir. He is also one of the members of a jury for Blitz and Junior's smithing challenge.

They are also used as source of food and they recover the next morning after being eaten, unless their bones have been broken. Marvin is more pessimistic and angry than Otis, and likes to criticize him.

Mortals

Mortals are human characters who live outside of the world of magic and gods, though some may be aware of their supernatural surroundings.

The Jackson family

  • Sally Jackson – Sally is Percy's mother, initially married to Gabriel Ugliano and later to Paul Blofis.[10] In The Lightning Thief, she works in a candy shop. When she was younger, she aspired to be a writer. She is nearly killed by the Minotaur, but is discovered to be alive in the clutches of Hades. Percy travels to the Underworld to free her.[5] In The Titan's Curse, Percy realizes she can see through the Mist, which she admits may have attracted Poseidon to her. Sally appears in all of the first five books. The Hidden Oracle reveals that she is seven months pregnant with Percy's baby half-sister. In the film adaptation, she is played by Catherine Keener.
  • Paul Blofis – Paul is Sally Jackson's boyfriend and later second husband, a high school English teacher whom Percy describes as looking like a detective from a police show. Percy and his mother eventually tell Paul the truth about the gods, and he only half believes them initially. But when Percy, Nico, and Mrs. O'Leary come unexpectedly to Sally's apartment, Paul fully believes and thinks it's "awesome!" He is a competent swordsman from stage combat training in college, and he assists in the fight to save Olympus in The Last Olympian.[10] Percy had first referred to him as "Blowfish" and as did Poseidon when he first heard about him saying "It is a shame because I rather like blowfish."
  • Gabriel (Gabe) Ugliano – Gabriel Ugliano was Percy's stepfather. He is described as a loathsome man who is rude to Percy and demanding toward Percy's mother Sally. It is implied that he was physically abusive to her. Percy later learns Gabriel's strong human stench hid Percy and his mother from detection by monsters. At the end of The Lightning Thief, Percy's mother uses the severed head of Medusa to turn Gabe to stone. Sally sold Gabe's petrified body as a poker-playing statue to the Sogo art gallery. In the film adaptation, he is played by Joe Pantoliano.[5]

The Chase family

  • Frederick Chase – Dr. Chase is Annabeth's father, a professor of military history. He first appears in The Titan's Curse. He owns a Sopwith Camel. He and his daughter have had many disagreements, which caused her to run away from home at age seven. He lives in San Francisco with his wife and two sons. In The Titan's Curse, he battles monsters on the Princess Andromeda with bullets formed from celestial bronze, and, at the end of the book, is able to mend his relationship with his daughter. Frederick also appears in the Magnus Chase & The Gods of Asgard series, where he is called by his brother, Randolph, to visit Boston and search for his long-estranged nephew, Magnus who had been missing for two years, after the death of his mother/ Fredrick and Randolph's sister Natalie.

She had a dispute over the trouble monsters caused when hunting Annabeth, and that was one of the factors that led Annabeth to run away from home at the age of 7. Though Annabeth describes her in a negative light, Percy is stunned when he actually meets Mrs. Chase, because she is kind and even wants Percy to tell Annabeth that she still has her home in San Francisco.
  • Natalie Chase – Natalie Chase was the younger sister of Randolph and Frederick, the aunt of Annabeth and the mother of Magnus. She distanced herself from her brothers and lived with Magnus as a single mother until her death at the hands of the wolves of Fenris Wolf when Magnus was 14 years old. She liked to walk with Magnus through sunlit parks, which Magnus realizes much later is a way for them to get closer with his father, Frey.
  • Randolph Chase – Randolph Chase is Magnus' and Annabeth's uncle and the older brother of Frederick and Natalie. He was a professor of history at Harvard before being expelled for theorizing on the location of the first great Norse settlement in North America.

However, the two separated when Hazel had to move to Alaska with her mother and never met with each other again since Hazel died shortly after. Though Hazel was led to believe that Sammy moved on quickly, a flashback she has in The Mark of Athena makes her realize that Sammy remembered her well into his old age and had made the then newborn Leo promise to meet with her in his behalf.
    • Rufus – Rufus was Hazel and Sammy's schoolmate in St. Agnes Academy for Colored Children and Indians during Hazel's first life. He was the leader of bullies who called Hazel a freak for summoning cursed stones and for being the daughter of a witch, but was always stopped by Sammy before he could hurt her even further.

Through charmspeak, Jane is controlled by Medea to lure Tristan into Mount Diablo where he is kidnapped by Enceladus, and then shooing Piper away so she could not interfere. Nevertheless, Piper manages to discover the trick and rescue her father. Afterwards, Jane is fired and replaced by Mellie the cloud nymph.

The Al Abbas family

  • Ayesha Al Abbas – Ayesha was Sam's late mother who worked as a doctor.

Other mortals

  • Beryl Grace – Thalia and Jason Grace's mother was a television actress with whom Zeus broke his oath not to have more human children. She is the first known mortal to bear children from both the Greek and Roman aspects of a god (in this case, Zeus and Jupiter). Thalia describes her as flighty, demanding and neglectful of both her children, and she would have run away from home earlier had Jason not existed. Beryl offering Jason to Hera's patronage, however, was the last straw that led Thalia to abandon her. Her stress turned her into alcohol, and she died several years before The Lightning Thief in a car accident. Melinoe impersonates her to instill fear on Thalia in the short story "Percy Jackson and the Sword of Hades" in The Demigod Files. In The Blood of Olympus, Jason encounters her mania, who wants her son to return to her so they can be a family again, an offer which Jason rejects. She then disappears in a hiss or a sigh of relief.
