Killer frost

Intro Killer Frost is a name used by several female supervillains and superheroes appearing in comic books published by DC Comics. The third incarnation of Killer Frost is Caitlin Snow, introduced in The New 52 continuity reboot.[18] She is a scientist who gains powers after H.I.V.E. agents attempt to kill her with a thermodynamic engine. In subsequent appearances, Snow seeks help from Firestorm and Martin Stein to cure her condition and joins the Suicide Squad and Justice League. After carrying out her vengeance, Caitlin continued to search for other sources of heat; she attacked a Norwegian research camp and stole their helicopter to fly to her hometown of Pittsburgh, where she encountered and fought Firestorm. While fighting Firestorm, Caitlin discovered that Firestorm's powers can temporarily heal her condition, and devoted her time to seeking and confronting him. She soon learned about the Firestorm Matrix and attempted to recreate it. Killer Frost was captured at some point after, and transported to Belle Reve where she was forced to join the Suicide Squad. After reforming and saving the world from Eclipso, Batman had her released on parole from Belle Reve and she joined the new Justice League of America.
