Subzero, his real name Dan Frost, is an ice-aligned superhero. He is a class-IV mutant, and was once corrupted to become a villain. His story began, when he discovered his powers, at the age of seven, while lost in Death Valley, Dan's brain went onto a "failsafe" and started creating a literal "iceshell" around Dan.

It is not known by the public, but if Dan hadn't had his powers, he would've died in Death Valley. At the age of twenty-five, after graduating college, Dan made a uniform out of Kevlar, spandex, and other materials, he then harnessed his power, training with it, mentally, physically, and with it, until he was in the shape of a bodybuilder. He was accepted for the Legion of Vigilance, and recruited in.
