Martin Stein

A brilliant but troubled nuclear physicist, Martin Stein designed an experimental reactor that was sabotaged and destroyed. Caught in the explosion alongside teenager Ronnie Raymond, Stein was fused with him to become Firestorm — the Nuclear Man — sharing a composite body while contributing the scientific genius behind their extraordinary powers.
