Fireshell

Origin
In a universe where the Cold War resuted in nuclear war, a soldier is naplamed. Just as he is about to die, the battlefield nuked and through some ridiculous comic book science he becomes a being made of fire. His body is made of white fire, while his head some how is a cooler, red fire. Everyone thinks he is a monster, until a scientist figures it out. He gives our hero a robotic suit, but before he can leave, a lab experiment gone wrong teleports him to Mascotia.

Powers
He has openings that he can open and close at will on this hands and feet. Using these he can fly, shoot fire, and create fusion reactions that he can use to create any element from only the surounding materials.

Personality
He's hot-headed. No pun intended. Otherwise, he acts like Batman. Wow.
