He has short deep brown hair, yellow cat-like eyes, and a scar on his forehead above his left eye that is usually partially hidden underneath his hair. He is a rather aloof man who likes making people laugh, despite his past as a trained assassin.

His sweet, funny, aloof personality disappears into a deadly, brutal, merciless killing machine when his friends are threatened or hurt.
