Character from Hunter x Hunter by Yoshihiro Togashi
Killua's grandfather — an elderly assassin whose Dragon Dive technique rains aura projectiles from the sky and whose philosophy on killing is terrifyingly professional.
Zeno is the Zoldyck family's patriarch emeritus — retired from active leadership but still the family's most experienced assassin. His Nen ability — Dragon Head/Dragon Lance/Dragon Dive — creates a dragon of transmuted aura that can be used for transportation, precision strikes, or area bombardment. He hired himself out to Netero for the Chimera Ant Palace invasion, raining Dragon Dive on the Royal Palace as the opening attack. He is pragmatic, professional, and views assassination as craft rather than cruelty. His rule: never kill anyone who isn't the target. It's not morality — it's professional standards.
Elderly but wiry with a long white mustache and sharp eyes. He wears traditional Chinese-style clothing. Despite his age, he moves with the precision of someone whose body has been a weapon for decades.
Also known as: Zeno, Grandpa Zeno
