OVA
Description
Killua Zoldyck is the third child of Silva and Kikyo Zoldyck, born into the infamous Zoldyck family of assassins. From birth, he was subjected to brutal and relentless training designed to mold him into a peerless killer. This training included torture to build resistance to pain, poisons, and electricity, as well as rigorous drills in stealth, martial arts, and assassination techniques. By the age of six, he was fighting in Heavens Arena, and within two years, he had reached the 199th floor. Despite being groomed as the family heir and showing immense promise, Killua grew tired of his predetermined life of killing. In an act of rebellion, he attacked his mother and brother and ran away from home to take the Hunter Examination, seeking to define his own path.
Killua's personality is a study in contrasts. On the surface, he is introduced as cheeky, cheerful, and mischievous, with a notable sweet tooth and a love for video games and snacks, especially chocolate. He is often rude to strangers and older people, in stark contrast to his best friend Gon's politeness. Beneath this playful exterior lies a highly intelligent and pragmatic individual. He is one of the quickest-thinking characters in the series, often analyzing complex situations with great ease and accuracy. His assassin training has given him the mentality of an adult, allowing him to remain level-headed and control his emotions even in terrifying circumstances, a trait that becomes more pronounced as the story progresses. However, his upbringing also instilled a ruthless and deadly side; he is unafraid to threaten or kill anyone who endangers himself or those he cares about. Despite the horrendous nature of his childhood, he has managed to retain a noble and positive core, a fact that other characters note as miraculous given the trauma he endured.
At the start of the series, Killua's greatest flaw is a deep-seated fear of opponents stronger than himself, a psychological shackle implanted by his older brother, Illumi, in the form of a Nen needle embedded in his brain. This needle forced him to retreat from any battle where victory was not certain, conflicting with his loyalty to his friends. His central motivation shifts from seeking personal thrills to proving himself worthy of standing beside Gon, whom he considers his first and most important friend. This bond becomes the anchor for his quest to forge an identity beyond his family's bloody legacy. Throughout the Greed Island arc and beyond, Killua works to overcome his ingrained fears, a struggle that culminates in him finally extracting the needle and freeing himself from Illumi's control during a life-or-death battle.
Killua's role in the story is that of the deuteragonist, serving as a foil and partner to Gon. Where Gon is impulsive and driven by emotion, Killua is analytical and strategic. Their friendship is the emotional core of much of the series. A key relationship that develops during the Greed Island arc is with Biscuit Krueger, a powerful and experienced Hunter who becomes his and Gon's Nen master. Biscuit recognizes Killua's potential but also his psychological weakness, and she pushes him harshly to mature as a fighter and a person. Another critical relationship is with his younger sibling, Alluka. Despite the family's fear and rejection of Alluka, Killua shares a deeply loving bond with her, eventually defying his family's rules and risking everything to save Gon by using Alluka's mysterious powers.
As a Nen user, Killua is a Transmuter, which means he can change the properties of his aura. He transmutes his aura into electricity, a feat made possible by years of enduring electric shocks as a form of training and punishment. This gives rise to his signature abilities. Godspeed allows him to move at incredible speeds and react instantly by using his electrified aura to override his nervous system. Thunderbolt is an offensive technique where he discharges a massive bolt of lightning from his hands. Beyond his Nen abilities, Killua possesses superhuman physical strength, having opened the 64-ton Testing Gates of the Zoldyck manor, and is a master of various assassin techniques such as the silent Shadow Step and the Rhythm Echo, which creates afterimages to confuse opponents. He is also highly proficient with weapons, notably a pair of custom-made, heavy yo-yos. Through his journey, Killua evolves from a gifted but emotionally hobbled child assassin into a confident and loyal young man who masters his own fate and fiercely protects the bonds he has chosen for himself.
