Zeno is the previous patriarch of the Zoldyck family. He only had one son Silva, who was born from an unnamed mother. He is the grandson of Maha Zoldyck. Being a member of the Zoldycks, Zeno was trained in a tender age the art of assassination. He developed a great resistance against all types of poisons, and high tolerance of electricity.
He appears to be on good terms with the Hunters Association's Chairman Netero, who hired Zeno to assault Ming Jol-ik's palace in East Gorteau in order to catch the Chimera Ant King off guard.
While Zeno is a witty old man, his advancing age has not dampened his quick thinking and speed in battle. Despite his senior citizen status, he is a very formidable tactician, and a skilled user of Nen. He remains calm and collected at all times and displays a unique sense of pragmatism. He takes satisfaction in being an efficient assassin and that seems to be his only conceit. Killing is just a job to him and emotion doesn't enter into it. He only risks his life if there is a reward to be gained. Zeno has high hopes on Killua, that is why he trusts the boy's ability.
While Zeno is violent and will kill without hesitation, he only does so when it is required to complete a contract; he avoids injuring innocents at all costs. Upon injuring Komugi accidentally, Zeno lost all desire to complete the contract on the Chimera Ant King and left, only after ensuring the fight between the King and the Chairman would not further injure civilians.
Zeno is an old man of medium height with grey white hair that stands up on his head, and has a Fu Manchu mustache. He also wears alternating signs on his garb that say either "A Kill A Day" or "Never Retire". Most of the time he is seen with his hands behind his back. His suit is black, white and gold.
