ZENO ZOLDYCK

Killua's eccentric, sharp-tongued grandfather. Wearing a ribbon that literally translates to "A Kill a Day," Zeno is a lethal, pragmatic assassin who treats fighting elite, world-ending threats like a standard 9-to-5 contracting job. His mastery of Nen allows him to manifest massive, destructive aura dragons, and even in his brief screen time within the TV series, the sheer scale of what he's casually capable of is never in doubt.
