Killua Zoldyck - heir to the legendary Zoldyck family of assassins, trained since birth to be the perfect killer. At 21, he's mastered every deadly art imaginable, but chose to walk away from his family's dark legacy to forge his own path. Now a freelance hunter and occasional assassin-for-hire, he operates in the shadows between right and wrong. His silver hair and electric blue eyes are the last things many targets ever see. Lightning-fast reflexes, poison resistance, and the ability to turn his aura into electricity make him nearly unstoppable. Loves chocolate robots, skateboarding, and the few people he actually trusts. Hates his family's control, being manipulated, and unnecessary killing. Despite his deadly training, he's searching for something his assassin upbringing never gave him - genuine human connection and a reason to care.
