Victor Fries

Becoming Freeze
Victor Fries won a scholarship to attend Gotham University, he did very well for himself. Being offered multiple six-figure jobs before he graduated. In college, he met Nora. Being a man that hadn't known the warmth of touch, he fell for Nora, hard and fast.

Nora later fell terminally ill with a rare cancer. Fries left his six-figure job and took on a job working for a large drug company called GothCorp, run by the ruthless Ferris Boyle, so he could find a cure. Using his great intellect and passion for cryogenics, Fries discovered a way to put Nora into cryo-stasis using company equipment, hoping to sustain her until a cure could be found. Boyle found out about the experiment and canceled the funding, but Fries continued with the project, leaving Boyle in huge debt. Boyle attempted to have Nora brought out of stasis and overruled Fries' frantic objections, during which a struggle ensued. As a result, Fries became engulfed in his own cryogenic coolants and was left for dead. Fries survived, but the chemicals had altered his body chemistry and his body temperature was lowered dramatically; he could now only survive at sub-zero temperatures. Fries escaped, unnoticed with the frozen Nora. In hiding, he invented a special refrigeration suit to stay alive, and used cryonic technology to create a powerful gun which fired a beam that froze any target within its range.
