Well, he's a human. (As of all my roleplay characters.) He was genetically tested on at birth. Scientists where testing a new formula. That new formula would take acouple years to genetically cope with the body. The subject would suffer severe pains and constant bleeding from every orifice until the formula would fully take place. The formula was a chemical that make the sells of the body more durable and acted as a stereroid/adrenaline for the cells. Litteraly giving the subject thick skin. the cells would be packed together tighter. This of course, would make sweating an impossability because of the swelling of the cell covering the pores. The chemical would also effect the brain. Making it work at at least 90% capacity, making it at work at least 10x better than a regular human. (Updates will be out soon)
