History:
Nobel prizewinning physicist Professor Martin Stein designed the Hudson Nuclear Facility, a fully automated nuclear generating plant. His former assistatn, Dr. Danton Black, falsely accused Stein of stealing his plans for the plant, causing the government to forbid the plant's opening until Black's charges were investigated. Stein, however, was determined to start the plant's operation that night.

That evening high school student Ronnie Raymond decided to join Edward Earhart's anti-nuclear power group, which was protesting the facility's opening. Raymond, however, objected when he learned that Earhart planned to blow up the plant. Stein activated the plant's nuclear reactor. Earhart knocked both Raymond and Stein unconscious and left them in the main reactor room with a bomb. Raymond revived moments before the bomb exploded, increasing the scale of the ongoing nuclear reaction. Raymond and Stein were bombarded with radiation and fused into the Nuclear man called Firestorm. Firestorm captured Earhart, became a super-hero, and eventually joined the Justice League of America.

Powers:
Through an act of will on the part of either man, Ronnie Raymond and Martin Stein can fuse to become the composite super-human being called Firestorm. Apparently Raymond and Stein must be within a certain undefined radius of each other in order to merge. When the merger occurs, the man who did not will the merger vanishes altogether, and Firestorm appears in the place of the man who willed the merger. Although the two men's bodies fuse, their consciousnesses remain mostly separate. Because only Raymond was conscious at the time of Firestorm's creation, it is his consciousness that controls the Nuclear Man, although Stein's can offer advice. If, however, Raymond is unconscious when the merger occurs, Stein's consciousness controls Firestorm. When Firestorm turns back to Raymond and Stein, the two men appear next to each other.

Firestorm's principal power is the ability to perceive and rearrange the atomic and molecular structure of matter, so as to change its form or transmute it. He can alter the density of objects, including his own body, even so as to render them intangible. Firestorm can project bolts of nuclear energy, fly at great speed, and absorb explosive force and radiation into his body harmlessly. However, if he directs his power against organic matter other than himself, he causes only an energy feedback that may harm him. Also, he cannot project energy bolts while he is intangible.

Firestorm's hair appears to be aflame, but this effect does not harm him.
