Killer Frost

After fusing with the ice emitted from a thermodynamic ultraconductor engine, Caitlin Snow gained the ability to project various forms of frozen water—including ice and snow—from the tips of her fingers.

One of the chilliest characters in the DC Universe, Killer Frost has been a villain, an antihero and a hero. First introduced as Crystal Frost, a former student of Professor Martin Stein, she was an adversary for Firestorm until her death. Shortly thereafter, her friend Dr. Louise Lincoln replicated the experiment that gave Crystal her powers and became the second Killer Frost. With a vendetta against Firestorm, she would fight the nuclear hero for years, on her own and as a member of the Suicide Squad and Injustice League.

The third and current Killer Frost is Dr. Caitlin Snow, a scientist at S.T.A.R. Labs. When Snow was attacked by agents of H.I.V.E. in the Arctic, she gained cold powers and used them to help Martin Stein and Steve Trevor rescue the Justice League. Since then, Snow has found herself on both the Suicide Squad and the Justice League of America, and demonstrated a desire and willingness to be more than the villainous legacy she’s inherited.
