Firestorm Matrix: Deathstorm 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 (e.g., transmuting lead into gold of equal mass) but he can also change its shape. He cannot, however, affect organic matter without painful, even lethal, feedback. This organic limitation does not extend to his person as he can change himself at will, allowing him to regenerate lost and damaged tissue, boost his immune system, shape-shift, and survive indefinitely without food, water and air. The Matrix also allows him to phase, absorb energy, project energy, control density and fly.
Deathstorm is actually Martin Stein of Earth-3, who in his universe discovered the Firestorm Matrix and decided to use the power for his own needs. Following the destruction of their own earth, Deathstorm followed the Crime Syndicate to Earth-1 so that they could take it as their own.
