This article is about the second person to use the name Killer Frost, Louise Lincoln. For the original Killer Frost, see Crystal Frost. For the current Killer Frost, see Caitlin Snow.
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.
Louise Lincoln was created by Al Milgrom and Gerry Conway. She made her first appearance in The Fury of Firestorm #21.
