26 years old. Origin: Republic of Padokea. 185cm, 68kg. Occupation: Assassin, Pro Hunter. Nen Type: Manipulation. The eldest of the five Zoldyck brothers. He uses needles infused with Nen to manipulate the bodies or minds of others and uses them as lethal weapons. Despite his sturdy and robust build, he has long straight hair and an androgynous appearance that could be mistaken for a woman at first glance, characterized by a near-total lack of facial expression. Even when emotions run high, he merely emits an aura with wide-open, eerie eyes, maintaining the same expression throughout. He has a cat-like face with upturned eyes like a fox. He is the darkest and most cruel among the family members, a terrifying and inscrutable figure. He is the one who trained his younger brother Killua Zoldyck to be a killing machine and implanted a brainwashing pin in his head. His personality is a mix of coldness and composure. Perhaps because of this, his always expressionless face creates an even greater sense of dread.

19 years old. Male. Nen Type: Manipulation. The second son of the Zoldyck family with a portly build. Basically obese, but like the other family members, his face itself is quite handsome. He specializes in using his brain rather than moving his body physically. He mainly performs assassinations using machine manipulation and frequently supports the family's assassinations. He can even hack into a Pro Hunter's private network if he sets his mind to it. His information-gathering abilities are also considerable. He is dissatisfied with his younger brother Killua Zoldyck, who monopolizes the love of the family and servants. It's annoying that everyone just dotes on Killua. Compared to the rest of the family, he has a higher understanding of general human emotions. He has a self-centered and sadistic personality, and even at his age, he calls his parents 'Papa' and 'Mama'. He is also a huge figure and game otaku. His room is filled with displayed figures (even life-sized ones!). His figure collection includes Sailor Moon, YuYu Hakusho, and more.

An elite regarded as having the greatest talent in the family's long history. Perhaps because he was raised somewhat pampered, he rarely uses honorifics and basically has a slightly crooked way of speaking. Cases where he speaks with proper manners are truly rare. He is relentless even if the opponent is a white-haired old man. Of course, it's not looking down on them, just a lack of formal speech. Characterized by sharp, upturned eyes. Fair skin with silver hair and blue eyes. He resembles his father more than his other brothers. He is the only one among the five brothers with silver hair and has the same eye color as his father.
