Killer Frost (Caitlin Snow)

Caitlin Snow was a young and bright scientist working for S.T.A.R. Labs assigned to an underfunded S.T.A.R. Labs Outpost #72 in the Arctic Circle, where the deceased researcher Dr. Louise Lincoln had been working on a Self-Sustaining Thermodynamic Ultraconductor Engine that could subvert the second law of thermodynamics in order to create perpetual motion. Caitlin became interested in continuing Lincoln's work, in spite of her colleagues warning her against it.
