As he grew older, Mick’s pyromania grew uncontrollable. Inspired by Central City’s band of costumed super-villains, the Rogues, Mick invented a handgun-sized flamethrower and a flame-retardant suit for himself. He adopted the code name “Heat Wave” as he began channeling his destructive urges into profit. Eventually, and despite his contentious relationship with the Rogues’ leader, Captain Cold, Mick became an official member of the criminal organization. Hotheaded and volatile, Heat Wave’s endless need to find an outlet for his peculiar obsession makes him dangerous and unpredictable, but not altogether evil. He’s sometimes turned over new—if slightly charred—leaves at the behest of superheroes, who’ve offered him more productive ways to turn up the heat.
