Silva Zoldyck

Silva Zoldyck (シルバ＝ゾルディック Shiruba Zorudikku) is Killua's father. A silent, pensive figure, Killua's interaction with him seems not much. He allows Killua to go along with Gon on their journey to find his father, but only because he sees it as a crucial step in his development as the head assassin of the Zoldyck Family. During the Southernpiece Auction in Yorknew City, Silva and Zeno are both hired by the mafia's dons to assassinate the Phantom Troupe, but withdraw from the job when their clients are killed due to a job taken by Illumi, Maha, and Kalluto. Silva recently appeared amid the assault on the Palace in East Gorteau, killing Cheetu on the way to pick up his father. He is an extremely capable fighter and nen-user, having killed an unknown member of the Phantom Troupe according to Killua. Only one of Silva's nen abilities has ever been shown. During Zeno and Silva's fight against Chrollo, he was seen creating large balls of energy from his hands.
