Background / History
Zeno is Maha Zoldyck’s grandson and Silva’s father. He regularly visits Maha, tending to him despite the older man’s insults. Zeno also worries about his father Jager: although the family describes Jager as dead or “living-dead,” Zeno believes the Demon Eye carrying Jager’s memories is evidence that he remains alive in some form 15 139 154.
Zeno initially judged his grandson Roy as a child with limited prospects as an assassin. After Roy opened his aura nodes, Zeno asked what he wanted from his new path. Roy answered that he wanted freedom and to reach the top; Zeno warned him that achieving it would require risking his life 42 43 316.
As Roy grew stronger, Zeno became one of his most vocal supporters. He refused Netero’s suggestion that Roy be adopted, rushed to Roy when he reported being cursed, and promised that Roy would not face the threat alone 126 140 141. Later, Zeno argued that Killua could inherit the family headship, but Maha’s legacy belonged to Roy 259.
Appearance
Zeno is an older man with striking white hair, a mustache, and a habit of standing with his hands behind his back 221 295 316.
- Hair: Described as wild, upright, or hedgehog-like; he sometimes ties it back while training 146 316 341.
- Clothing: His customary robe bears the words “One Kill A Day, Active Duty for Life” 139 189 305.
Personality
Zeno pairs an assassin’s practical judgment with open concern for his family. He tells Roy to finish enemies promptly so Nen abilities cannot give them another chance, but reacts immediately when Roy calls for help and stays with him afterward 55 140 141.
He also enjoys teasing his descendants and trading barbs with Netero. Around Maha, however, he accepts scolding and continues looking after him 45 237 305 345.
