Synopsis
Zeno Zoldyck is an elite professional assassin, an exceptionally skilled Nen practitioner, and the father of Silva — which makes him Killua's grandfather.
He is an old man of medium height with grey-white hair standing up on his head and a Fu Manchu moustache. His garb carries slogans such as "A Kill A Day", and he is usually seen hunched forward with his hands behind his back.
A witty old man, he has lost none of his quickness of thought or of movement with age: he is a formidable tactician and a skilled Nen user. Always calm and collected, Zeno brings a distinctly practical outlook to everything. His only real conceit is his own efficiency — killing is a job in which emotion plays no part, and he risks his life only where there is something to be gained. He has high hopes for Killua.
He has known Chairman Isaac Netero since he was an infant.
His techniques centre on dragon-shaped aura — Dragon Head, Dragon Lance, Dragon Dive. He matches both Silva and Chrollo for speed, and can cut down an entire armed crowd in seven seconds. Voiced by Hiroshi Ōtake in the 2011 series and Tadashi Miyazawa in the 1999 one.
