Before the accident he was manipulative(pretty good at that), he had high capacities (and still does), he's very reserved and mature, hard to get to his core. Probably has Mommy Issues.

After the accident, he ended pretty traumatized. Ran over by a truck, he's horrified of crossing streets now. He can be heard crying some nights, he has night terrors and he's paranoid. He doesn't trust anyone. 

He's been before in several (fist-fighting) gangs, like Toman, Valhalla, Moebius and Tenjiku.
