Kid and Killer are foils of each other in the best way. Kid is loud, impulsive, and boisterous while Killer keeps him in check as the more quiet and rational of the two. Both are large, well built men Killer is 195 cm and Kid is 205. Killer has his face covered by a blue/white striped mask with holes, as well as waist length, blond hair and a fluffy stubble. Kid has short, jaggy red hair and red-orange eyes. He also has a huge metal arm replacing his left arm, which was lost in a fight.
