Illumi Zoldyck

Overview

Illumi Zoldyck is the eldest son of the legendary Zoldyck assassin family. Known for his emotionless demeanor, mastery of disguise, and chilling presence, he is both a loyal family member and a manipulative force who exerts control over Killua’s life.

During the Hunter Exam, Illumi infiltrates under the alias "Gittarackur," hiding his true face with needle-based transformations. His influence extends beyond assassination, as he later joins the Phantom Troupe and remains one of the most dangerous manipulators in the series.
