The leader of the Phantom Troupe, he is a dangerous individual who takes what he desires without regard for others. He doesn't plunder for profit, instead admiring his spoils briefly before selling them off. As a Specialist, his Skill Hunter ability allows him to steal the powers of Nen users, prompting him to frequently analyze himself and those around him due to both his nature and the demands of his ability. Though he kills without hesitation, he is equally indifferent toward his own death, displaying a mindset far removed from that of ordinary people.
