He is a former associate of the Phantom Troupe and a magician/serial killer who is always in search for strong opponents, going so far as to spare those who have great potential, such as Gon Freecss and Killua Zoldyck.

He is very experienced in combat and nen. His main ability is bungee gum. Hes kinda pervy
