Zeno Zoldyck

Zeno Zoldyck, one of the best elderly anime characters of all time, is a very proficient Nen practitioner and a contract killer. He is Killua Zoldyck's grandfather and Silva Zoldyck's father. Deadly individuals abound in the Zoldyck Family. That Zeno Zoldyck's name is sufficient to frighten away his enemies is therefore not surprising. He typically stands with his hands behind him and sports a noticeable mustache, but don't assume it makes him helpless.

Even at his advanced age, Zeno possesses unfathomable power and agility, making him a skilled Nen user and combat strategy. Even though he is an elderly citizen, he is an extremely strong tactician and adept Nen user. Even Chrollo Lucilfer acknowledged that defeating Killua's grandfather would require all of his power. Because of how deadly and swift his fists are, Zeno defeats opponents without the use of weapons.

Even though Zeno Zoldyck is a ruthless and unreserved killer, he never hesitates to kill to fulfill a contract and will stop at nothing to protect innocent people. Fortunately, he honors agreements. Zeno will not harm or even murder another person if it is not necessary. He is pragmatic and quick-witted, but he can't shake the windbag reputation of an elderly man. To Silva's anger, he frequently boasts about every new experience he has.
