Killer Frost

Dr. Louise Lincoln, also known as Killer Frost, is a character from the DC comics.

Dr Louise Lincoln was working in a lab in New Jersey when she was approached by her college friend and mentor Crystal Frost, who had some time previously been involved in an accident that turned her into Killer Frost. Lincoln discovered that Frost was dying because of her powers. Following their encounter and Frost's death, Lincoln became obsessed with seeking revenge against the person she blamed for her death- Firestorm. To this end she recreated the accident that gave Frost her powers, becoming the new Killer Frost.

Personality
After her friend's death, she decided to repeat the experiment as a last respect to her former mentor, and became the second Killer Frost. She became just as ruthless as her predecessor and began her own personal vendetta against Firestorm whom she blamed for Crystal's death.

Abilities
Killer Frost has the power of thermokinetic cryokinesis. She is able to absorb heat and transmute it to extreme cold temperatures, which manifests in the generation of ice structures of various sizes and freezing gusts of wind. She can use this power to create ice surfaces upon which she may slide, and also to create weaponry or defensive structures. She can also reduce the temperature of a person's body until they freeze to death. She is an intelligent and skilled scientist.

Trivia

 * Prior to becoming Killer Frost, Louise Lincoln required prescription eye-glasses. Her transformation into Killer Frost appears to have corrected any eye sight irregularities and she no longer wears them.
