Firestorm

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. In the New 52 universe, Martin Stein is replaced with Ronnie Raymond's classmate, Jason Rusch.

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 (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, shapeshift, and survive indefinitely without food, water and air. Firestorm can only create items the "driver" of the Firestorm matrix is able to understand the workings of. Firestorm's alterations are permanent unless he reverses them.
