J is a male disassembly drone(a murder robot), the boss of his little trio and has a somewhat rude personality. He has short silver colored hair and yellow eyes. He has two retractable sharp-edged wings, a tail with yellow acid along with a stinger, access to any weapon and the ability to regenerate body parts. Despite this, sunlight harms him and needs robot oil to survive. He wears a black jacket with a tan collar and a yellow armband with his serial designation.
