About
Killua Zoldyck is the third child of the infamous Zoldyck assassin family, raised from birth to be a perfect killer. Trained in torture, poison resistance, and silent killing, he rebelled against this life and ran away from home to take the Hunter Exam, where he met Gon Freecss. That friendship changed him, and Killua spent the rest of his journey learning what it means to fight for someone else rather than for duty or for the family name.
Beneath his calm, playful surface, Killua carries a darker side shaped by his brother Illumi's conditioning. The Needle embedded in his brain made him flee from any opponent he judged stronger than himself, until Gon helped him confront it and break free. From that point onward, Killua's growth accelerated, leading him to master lightning-based Nen and to protect Alluka, his hidden sibling, on his own terms.
Abilities
Godspeed
Charges his body with lightning to move and react at inhuman speed, with two modes: Speed of Lightning for automatic reflexes and Whirlwind for manual control.
Lightning Palm
A close-range strike that discharges electricity from his hand, able to stun or burn opponents on contact.
Thunderbolt
A long-range lightning bolt fired from his fingers, capable of striking distant enemies with high-voltage Nen.
Assassin Techniques
Raised as an assassin, he has pain tolerance, poisoned claws, snake-like reflexes, and silent movement trained since infancy.
Notable battles
Killua's clashes against his brother Illumi, the Phantom Troupe, the Chimera Ant officers, and the Bomber Genthru each reveal a different facet of his character — the assassin's coldness, the friend's loyalty, and the new Hunter who finally chooses his own path. His duel against Shoot, his defense of Gon against Pitou, and his lightning charges through the Palace Invasion are some of the most thrilling moments of the series.
