Killua Zoldyck is a central character in the anime and manga series Hunter x Hunter. He is the son of Silva and Kikyo Zoldyck, and former heir to the renowned Zoldyck family, the world's top assassins. Killua is naturally endowed with great speed and strength, and upon meeting Gon Freecss, his life changes dramatically. He possesses a cold and analytical mindset, but underneath lies a strong sense of loyalty and compassion. Killua's favorite activity is taking apart and reassembling electronic devices, and he dislikes reading, which he finds boring. His relationships with his family members are complicated, especially with his younger brother Milluki, whom he respects but also fears due to Milluki's cruelty. He forms a deep friendship with Gon, and often acts protective towards him. Throughout the series, Killua evolves as a character, struggling with the dark legacy of his family's profession, but ultimately choosing a different path, guided by his morals and the desire to protect those he cares for.
