About:
Martin Stein, also known as Deathstorm, was a person who inhabited Earth-2. When the particle accelerator exploded Martin's body got fused with that of Ronnie Raymond. Ronnie then forced Martin to stay in his body and never to be let out again. This went on for so long that Ronnie couldn't even hear Martin's voice anymore.

Ronnie then went on to become a meta-human villain working together with his wife Killer Frost. They then worked for Francisco Ramon who in his place worked for Zoom.
