Firestorm, The Nuclear Man #1 (December 6, 1977) This Day In Comics
High school student Ronnie Raymond and Nobel Prize-winning physicist Martin Stein were caught in a nuclear accident that allowed them to fuse into the “nuclear man” Firestorm. Firestorm debuted in Firestorm, The Nuclear Man #1 (December 6, 1977).
Due to Stein’s being unconscious during the accident, Raymond was prominently in command of the Firestorm form with Stein a voice of reason inside his mind, able to offer Raymond advice on how to use their powers without actually having any control over their dual form. Banter between the two was a hallmark of their adventures. Stein was initially completely unaware of their dual identity, leaving him concerned about his unusual disappearances and blackouts, but Ronnie was eventually able to convince him of the truth, allowing them to bond as separate individuals rather than as parts of a whole. After the accident, Firestorm took to defending New York City from such threats as Multiplex and Killer Frost. Firestorm has the ability to rearrange the atomic and subatomic structure of inorganic matter, rearranging subatomic particles to create objects of different atomic characteristics of equal mass. He can not only change and transmute the atomic composition of an object but he can also change its shape.
