    Martin Stein was created by Gerry Conway and Al Milgrom, first appearing in Firestorm #1.

    Pre/Post Crisis

    The original Firestorm was distinguished by his integrated dual identity. 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. 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. Banter between the two was a hallmark of their adventures. Initially Stein was completely ignorant 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. By the series' 100th issue, Stein learned that he was destined to be the true Fire Elemental and would have been were it not for Ron Raymond also being there by circumstance. Raymond and Arkadin were returned to their old lives, and Stein as Firestorm was accidentally exiled to deep space in the process of saving the Earth. He thereafter spent many years traveling through space as a wanderer, returning to Earth on only two occasions: the War of the Gods crossover event, and again in the JLA spin-off, Extreme Justice #5, where Stein cured Raymond of his leukemia and allowed Raymond to retain the original Firestorm persona on his own.

    With the emergence of The Superman Theory, a conspiracy theory which states the exponential increase in metahuman activity, specifically in America compared to the rest of the world is a result of illegal government experiments. Firestorm is one of the heroes in suspicion, Firestorm adamantly denies such claims. Against the wishes of Stein Ronnie flew to Russia to confront Pozhar, one of the biggest proponents of The Supermen Theory.

    Whiles in Russia Firestorm got into a fight with The People’s Heroes. After an attack by Negative Woman, Firestorm fell to the ground where he got overwhelmed by protestors. In a moment of confusion Ronnie lost control and transmuted all the citizens into glass. Firestorm took one glass statue to reverse the transmutation but was unable to until he got some encouragement from Superman. The next day Firestorm returned to the accident site with a child he reverted but was immediately attacked by the Russian military.

    Superman tried to deescalate the situation however it turned into another fight against The People’s Heroes. Mid fight someone released a detonation which killed the civilians, comatose Superman and knockout Firestorm. When Stein and Ronnie woke up they are on a Justice League shuttle heading to Mars because the League believe to person responsible for framing Firestorm for the explosion is located there.

    During the battle Dr. Manhattan showed Ronnie past events which confirmed Stein intentionally caused the accident resulting in Ronnie and Stein merging into Firestorm as well as Ronnie was shown due to resembling Stein’s late son. Stein motivation to become a metahuman was so he can embed himself in metahuman communities to spy on behalf of US Government Department of Metahuman Affairs. The JSA investigation uncovered Stein and the D.M.A had a hand in creating Metamorpho, Creeper and several other metahumans.

    Earth 3 (Post Flashpoint)


    Martin Stein was considered to be one of the foremost minds in theoretical physic and biology. He would lure homeless people into becoming his guinea pigs in his quest to discover the means of creating life from death. Eventually he drew the attention from the Crime Syndicate's enemies, who hired him. Instead of helping them, he used their facilities to further his work, and began to experiment on himself. He fused his body and mind with those of a corpse, and became Deathstorm.

    Following the destruction of their own earth, Deathstorm followed the Crime Syndicate to the Earth 0 so that they can take it as their own.

    Using his greater knowledge of the Firestorm Matrix, is able to use the superhero Firestorm as a prison for the other heroes by imprisoning them inside the Matrix while in the process making Firestorm's body a ticking time bomb. From there, the Syndicate goes on to take control of the earth, using the Secret Society as their army. Deathstorm was betrayed by Superwoman who let Mazahs crush his head to absorb his powers.

    Dark Multiverse


    Martin Stein was the creator of the Firestorm Matrix in his universe, he shared it with Ronald Raymond and Jason Rusch until they died. He then merged with their corpses similar to Deathstorm and transformed into a demonic entity known as Infernal.

During a confrontation Brimstone scarified himself to stop Infernal.
