Biography
Little is known about Martin's early life, but similar to his Earth One counterpart, after the particle accelerator explosion, he was exposed to the effects and merged with Ronnie Raymond. But unlike his Earth One counterpart who became the hero known as Firestorm, Ronnie resorted to trapping Stein within his body to the point where Ronnie can no longer hear Stein's voice. Ronnie eventually became a villain known as Deathstorm, and refused to change back to his human forms. He then started working for Cisco Ramon, the criminal called "Reverb" who works for Zoom.
