Nobel Prize winning physicist Dr. Martin Stein designed a fully automated nuclear power plant. Stein was accused of espionage by his former assistant Dr. Danton Black (Multiplex), and the government forbid the power plant's operation until the investigation was complete.

Determined to begin operation of the power plant Stein circumvented the government injunction. Simultaneously an anti-nuclear rally, attended by high-school student Ronnie Raymond, was in progress. Raymond learned that friend and fellow protester Edward Earhart planned to detonate a bomb in the plant, and attempted to stop him. Along with Dr. Stein, Raymond was rendered unconscious by his Earhart who left them to die in the ensuing explosion. Reviving mere moments before the explosion Raymond and the unconscious Stein were exposed to unprecedented amounts of radiation fusing them into the elemental being known as Firestorm the Nuclear Man.
