Just another guy, with a very unique power.. Although he has many abilities to unlock, he has used his ability to amass a quite a fortune.
Aaron is a quiet, cunning, and extremely perceptive individual. He often uses his powers to gain something he desires or to make his life easier in general. He is aloof and generally has great control over his emotions, which is required of him to maintain control over such a powerful ability.
Biokinesis
Aaron is capable of controlling the biological structure of his own and other people's bodies. Theoretically capable of rewriting someone's genetic structure at will. He can produce biomolecular energy at will to affect organic matter he touches, allowing 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. He hasn't reached his full potential yet, but he still has good control over his ability. He has 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. His control over his abilities is now so refined that he was not only capable of giving someone a brain tumor, but even giving it a specific shape.
Because of his control over his own biology, Aaron has proven to be very difficult to treat medically. He usually passes out after pushing his powers too far and remains in a coma for some time.
