Caitlin Snow / Killer Frost

Biography
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, however. Dr. Caitlin Snow is 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, and she soon discovered the place had been infiltrated by H.I.V.E. agents. When they tried to kill her inside the engine, Caitlin 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 Firestorm's blasts can temporarily heal her condition. When he was declared dead by the Crime Syndicate, she loses hope for a cure.

Killer Frost mourns the disappearance of Firestorm (who was the only person who could provide her with the unlimited heat she needs for sustenance). She is distracted though by a woman's cries for help as her son is trapped in a flaming car. Though she is tempted to steal the woman's heat, the talk of fire intrigues Killer Frost. Investigating, she discovers that a supervillain calling herself Hotness is causing fires everywhere. Gleefully, Killer Frost catches her and steals her heat, killing Hotness. Despite having done nothing else to help, the boy is reunited with his mother, and Killer Frost resumes her search for Firestorm.
