Flash (Barry Allen)
Escaping a prison transport by leaping from the window, Mark Mardon fled to his brother's house only to find him dead. Mardon's brother, Clyde, a scientist, had just discovered a way to control the weather before dying of a heart attack (although recent evidence implies that Mardon murdered his brother and either lied about or blocked out the memory of finding his body). Mardon took Clyde's notes and used them to make a wand to generate weather and embarked on a criminal career as the Weather Wizard, sometimes using his powers on a small scale (such as zapping someone with lightning) and sometimes a larger scale (imprisoning a town in winter), almost always facing defeat by the Flash (Barry Allen).
