Joshua Foley (Earth-513)

Biography
Josh Foley was born in Queens, NY, and grew up with two older brothers, unaware of his mutation. He was always a golden boy -- good at sports, admired by his friends and attractive to girls. Josh also happened to be the popular one who would often pick on the the outcasts, and was also once a member of a mutant hating group, the Reavers, led by Donald Pierce, because his best friend Duncan asked him to. During a fight, Josh discovered he was a healer by healing one of his fellow Reavers. By knocking him out, he was able to hide this for a short time until he felt compelled to heal another, mortally-injured friend. When the Reavers discovered Josh was a mutant with healing powers, they rejected him and retreated. He angrily went home, only to find the Reavers waiting for him, where they delivered a severe beating, and when his parents discovered he was a mutant, they disowned him. They handed his legal guardianship over to Marvel High, where they thought he would be in good hands.

At a school party, Joshua tried to help Alex Summers, who was apparently dealing with a big amount of energy he had pent up. When he tried to touch Alex in a (fairly ridiculous) attempt to "heal" him, his energy left his body in the form of heated plasma, nearly incinerating Joshua. With his last strength, he healed himself, with the side effect that his skin turned golden. Afterwards, he passed out and remained in a coma for a while.

Powers
Biokinesis: Elixir is capable of controlling the biological structure of his own and other people's bodies. He is theoretically capable of rewriting someone's genetic structure at will. He can produce biomolecular energy at will to affect organic matter he touches. This allows him to heal physical damage done to his body or the bodies of others, reactivate suppressed mutant abilities, repair cerebral functions, and alter the composition of his own molecules in certain ways. However, he hasn't reached his full healing potential yet (and is not really aware of it). Currently he is capable of basic healing, having successfully healed broken bones, severe burns and even a mortal stab through the chest. His ability is by close proximity - he tends to touch his targets, but can heal through clothing.

He mostly uses his powers to heal fellow students after fights, accidents, or to cure them from hangovers.

Recently, he discovered that he cannot only use his powers to heal, but also to hurt a person, but he didn't test that on anyone else but himself yet.
