Fictional character biographies

Crystal Frost

Crystal Frost was the first incarnation of Killer Frost, appearing in Firestorm #3 (June 1978). While Frost was studying to be a scientist in Hudson University, she fell in love with her teacher, Martin Stein. While working on a project in the Arctic, Frost was upset to learn that Stein did not reciprocate her feelings. Frost accidentally locked herself in a thermafrost chamber but survived, being transformed in a way in which she was able to absorb heat from a living being and project cold and ice. Calling herself "Killer Frost", she began her murderous crusade against men and clashed with Firestorm on many occasions. Killer Frost eventually died after she absorbed too much energy from Firestorm. Crystal Frost has been identified as one of the deceased entombed below the Hall of Justice. Her body was reanimated as a Black Lantern.

Louise Lincoln

Dr. Louise Lincoln is the second incarnation of Killer Frost. She first appeared in Firestorm (vol. 2) # 21 (March 1984) and used the name "Killer Frost" in issue #34. Lincoln was a colleague and friend to Crystal Frost. After her friend died, she decided to repeat the experiment as a last respect to her former mentor, and became the new Killer Frost. She became just as ruthless as her predecessor and began her own personal vendetta against Firestorm, whom she blamed for Frost's death. She briefly served as a member of the Suicide Squad and sold her soul to Neron for more power.

During the Underworld Unleashed event, Killer Frost attacked Hawaii, freezing part of the islands before being stopped by Superboy and Knockout.

After a group of mobsters put out a hit on Lois Lane, Killer Frost rescued her from Solomon Grundy, only to then leave the reporter bound and gagged on a set of train tracks, hoping to take the credit and reward for Lane's death. Her plan was foiled by Superman who rescued Lois before the train could hit her.

Killer Frost was later freed by Effigy and the two had a brief flirtatious partnership before she was apprehended by Green Lantern.

In the Superman/Batman "Public Enemies" arc, Killer Frost was one of many supervillains seeking to earn a $1 billion reward offered by President Lex Luthor to sanction Superman and Batman, whom he considered treasonous. She teamed with Mister Freeze, Icicle and Captain Cold in an attempt to ambush the two heroes in Washington D.C., but all four were defeated. They attacked in a second wave, along with more villains such as Giganta and Gorilla Grodd, but a similar backup of superheroes battered them all into submission. It was later discovered in Superman/Batman #3 that this ice-themed team of villains was being mind controlled by Grodd.

Dr. Light hired Killer Frost and Mirror Master to attack Green Arrow and Black Lightning at a hospital in Chicago, Illinois, where Kimiyo Hoshi was being held. Green Arrow stopped Killer Frost by firing an arrow filled with Greek fire into her thigh. Unable to absorb the heat from the arrow, she was defeated in Green Arrow (Volume 3) #54-55.

Around this time, Lincoln discovered that she had contracted cancer, and tricked Jason Rusch, the new Firestorm, into curing her. With her health and powers restored Killer Frost went on a rampage, only to be defeated when Jason used his abilities to reverse his alterations to Lincoln's body, returning her cancer.

Killer Frost returned during the events of One Year Later, where she had apparently entered into a relationship with Mr. Freeze. Together, the two villains went on a killing spree in Manhattan, hoping to draw Firestorm into an elaborate trap. Once the hero arrived, Killer Frost used a device to send both of them into space, where she sought to absorb the heat energy of the sun. Firestorm narrowly managed to stop her plan, and both Killer Frost and Mister Freeze were taken into custody by Batman. As they were being sent away, Killer Frost angrily revealed to Mister Freeze that she had only been using him as a pawn, and had no romantic interest in him.

Killer Frost was later seen battling Firestorm in the Justice League of America Wedding Special until Lex Luthor, Joker and Cheetah arrived, subdued Firestorm, and invited Killer Frost to join the new Injustice League. She then appeared in Salvation Run, where she was sent to the Prison Planet after having been defeated and captured by the Suicide Squad.

In DC Universe #0, she was seen as the member of Libra's Secret Society of Super Villains. She is later seen as one of the villains sent to retrieve the Get Out of Hell Free card from the Secret Six, and ultimately helped deal the killing blow to the crazed supervillain Junior and the troubled vigilante known as the Tarantula. A short time after this encounter with the Secret Six, Killer Frost appeared as one of the participants in a metahuman fighting tournament in Tokyo. She was defeated by Wonder Woman and Black Canary, who had disguised themselves as villains in order to take down the tournament from the inside.

Caitlin Snow

In September 2013, as the "Villains Month" part of the Forever Evil storyline during The New 52, Killer Frost was featured in the one-shot Justice League of America #7.2, also titled Killer Frost #1. She can also be seen on the cover of Forever Evil #1, which hints at her involvement in that series. The issue revealed this is yet another version of Killer Frost, Dr. Caitlin Snow, a scientist sent to S.T.A.R. Labs Outpost #72 in the Arctic to work on a thermodynamic engine whose creator had committed suicide. Snow soon discovered the place had been infiltrated by H.I.V.E. agents. When they tried to kill her inside the engine, Snow frantically ripped off the coolant system, merging her body with ice. Transformed into a heat vampire, she killed the H.I.V.E. agents and continued to search for other sources of heat, eventually discovering that Firestorm's blasts can temporarily heal her condition. When he was declared dead by the Crime Syndicate, she lost hope for a cure.

Powers and abilities

All versions have shown the ability to absorb heat from external sources and transmute it into waves of cold. Using these powers, Killer Frost can create an ice-sheen across her entire body and generate objects composed completely of ice, such as projectiles and defensive walls. She can also instantly freeze animate matter through physical contact. In pre-Crisis on Infinite Earths appearances, she had the ability to make men fall under her control with a kiss.

Labs team which supports Barry Allen (Grant Gustin) in using his powers to save lives as the Flash, and eventually becomes good friends with Barry. Caitlin struggles with the loss of her fiancé Ronnie Raymond (Robbie Amell), who was believed to have died in the accident which gave Barry his powers. Caitlin uncovers the truth behind what happened to Ronnie - instead of dying, Raymond merged with Dr. Martin Stein, becoming Firestorm. With the help of S.T.A.R. Labs, Snow stabilizes Ronnie's condition, allowing him to once again function as an individual. In the season finale Caitlin and Ronnie marry. When Barry runs through the Speed Force, he sees moments from the past, present, and future, one of which shows a glimpse of Caitlin as Killer Frost. In the second season of The Flash, Ronnie flies up to the singularity to stop the destruction of Central City, resulting in his apparent death and sacrifice as a hero. Later, when the Earth-2 Dr. Wells arrives, his metahuman sensory watch reveals that she is not a metahuman.

They were eventually defeated by the Justice League.
• The Justice League version of Killer Frost also appears in the sequel series Justice League Unlimited, again voiced by Jennifer Hale.

The ship held the remains of a Viking prince believed to hold the key to invincibility. When an avalanche threatened a nearby lodge, Killer Frost was forced by the Martian Manhunter to save the people there. Later, when the Secret Society mutinied on the way to Brainiac's former lair, she joined Grodd's faction but was defeated by Toyman.
