As a child, Mick Rory was obsessed with fire, to the point where he burnt his house down and merely watched the flames engulf it, rather than getting help. During a school field trip, one of his classmates locked him in a meat locker, giving him a hatred of ice. As payback he locked the same classmate in a wardrobe in his new house and burnt it down with the classmate inside. In his adulthood Mick got a flamethrower gun and an asbestos costume to commit crimes in Central City, and became part of The Flash's rogues gallery. Among the Rogues, he has a "frenemy" in Captain Cold. (Presumably due to his hatred of ice).
