Illumi Zoldyck

Standing tall at 185 cm, Illumi is a master manipulator and the oldest brother of Killua. He’s not just any sibling; he’s a seasoned assassin with a chilling reputation, thanks in part to the rigorous training he and their father put Killua through. During the Hunter Exam, he cleverly disguised himself with special pins that altered his facial structure so only his voice gave him away. This guy radiates an oppressive, menacing vibe that even strikes fear into Killua's heart. There's something about him that makes everyone feel uneasy, adding an air of mystery that keeps people on edge.
