Zapp Renfro is a member of the Libra organization and master of the Big Dipper blood fighting style along with Zed O'Brien who was taught by Raju Jugei Shizuyoshi. A tall, lanky, white haired black man with dark skin. He typically wears a black, long-sleeved muscle shirt under a white suit and shoes and is often seen smoking a cigar. Described as a hotheaded, hyper-sexual juvenile punk, he is easily annoyed and quick to lose his temper; his juvenile actions often get him and others into trouble. Despite this, he is supposedly good at looking after new members, and so was assigned as Leo's partner/bodyguard. He is also something of a ladies man, possessing several lovers in town. For reasons unknown, he regularly tries to fight Klaus to beat him, only to be routinely smacked down.
