Killer Frost (Crystal Frost)

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.

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.
