This article is about the first person to use the name Killer Frost, Crystal Frost. For the second Killer Frost, see Louise Lincoln. For the current Killer Frost, see Caitlin Snow.
Crystal Frost was studying at Hudson University towards a degree in engineering physics when she fell in love with one of her professors, Martin Stein. Sometime later, having gained her doctorate, she was working on a project in the Arctic and requested Stein's assistance, with the ulterior motive of reuniting with him. However, he rejected her advances, and, distraught, she accidentally locking herself in a thermafrost chamber, Frost gained the ability to generate waves of intense cold. Taking the name Killer Frost, she became a super villain bent on destroying men.
Crystal Frost was created by Gerry Conway and Al Milgrom. She made her first appearance in Firestorm, The Nuclear Man #3.
Major Story Arcs
Secret Society of Super Villains
Killer Frost joins forces with several other villains to create the Secret Society of Super Villains. Lead by the Ultra-Humanite from Earth-2, they seek to kill their arch-nemeses in order to force the universe to remove all heroes. She confronts Firestorm on Earth-2, and successfully brings a heavy roof down on his head, sending him to limbo. The multiverse removes heroes from Earth-2, but not from Frost's home on Earth-1. She and several other villains turn on Ultra-Humanite and the other Earth-2 villains, but are transported home and trapped there. Taking charge of the group she directs them against their own Justice League, successfully freezing Green Lantern and beaming up to their satellite. Using the inter-dimensional transmatter machine she successfully sends Cheetah in to break the heroes out of their containment. After the Justice Society and Justice League defeat the Earth-2 Secret Society, she and her compatriots meet them in limbo and seek their revenge.
Killer Frost repeatedly clashes with Firestorm, but each time she is defeated and imprisoned. During one period of escape from prison she goes to Louise Lincoln, a former college friend, who discovers that Killer Frost is dying due to her powers. She begins attacking people to draw out their heat, killing them in the process. She is confronted by Firestorm, and, believing that his heat may be the only thing to cure her disease, she induces him to give her all of his heat power. She is overwhelmed, and atomized by the outpouring of heat.
Entombed below the Hall of Justice, Killer Frost is raised from the dead by a Black Lantern ring. Her activities during the Blackest Night are unknown, she presumably engages in the war on the living. She is returned to the grave following the conclusion of the Night.

Powers and Abilities
Killer Frost has the power of thermokinetic cryokinesis. She is able to absorb heat from her surroundings and transmute this heat into waves of intense cold; thus, any heat or heat-based weaponry makes her more powerful. She can generate this cold to a variety of effects, including creating ice structures, waves of frigid air, and freezing objects solid. She is able to absorb heat from others, and often does so by kissing people and lowering their body temperature until they freeze to death.
