Code Name: saber.
Nationality: what exactly do you want here? actual race, or just where he was born? after all, you can be irish and born in japan, and vice versa.
Power: can control metal, and his skin is aactually a form of metal that looks and feels like normal flesh.
Bio: saber has little history, having long ago lost his memory after an accident he barely survived. essentially, a large vat of molten metal tipped over, and the metal completely coated him. he woke up months later in the hospital, finding that his skin had adapted to the metal, and given him control of any metal in his hand, or his flesh itself. he can be very serious at times, but overall he's very laid back and fun loving.
there are a few limits to his power: one, there has to be a direct connection between his hand and the metal. for example, two metal bars are touching, and he grabs the first one. he can manipulate both, as long as they're still touching. if they stop touching, he can only manipulate the one in his hand, obviously. as for the skin thing, the muscles underneath are unaffected, and he can't form new skin. the main use of the metal-skin is he can attach metal objects directly to his flesh, which can spawn such great fun-filled objects as wrist-cannons and a shoulder mounted rocket launcher.
