8 Facts About Killua Zoldyck in the Anime 'HUNTER X HUNTER' That Are Rarely Known, Reluctant to Be the Heir of the Family

Killua comes from the Zoldyck family, known as the most dangerous assassin family in the world. Since childhood, Killua has been rigorously trained to become the perfect assassin, including being taught killing techniques and torture.

Although trained as a killer, Killua has a personality that is the opposite of his family's. He is more relaxed, cheerful, and often shows a caring side, especially towards his friends like Gon, Kurapika, and Leorio.

Killua masters the Transmutation type Nen technique that allows him to control electricity. The Godspeed technique is one of his strongest abilities, enabling him to move at incredible speeds, almost unstoppable by enemies.

Killua refuses to continue the family tradition as a hired killer. He rebels against his family and chooses to embark on adventures with Gon, seeking freedom and a life different from what was planned for him.

Alluka, Killua's younger sister, has a very powerful supernatural ability, which is to manipulate reality through an entity named Nanika. Killua is very protective of Alluka and is the only family member who treats Alluka with affection.

Killua often serves as the brains behind his group's strategies. His skills and experience as a hitman give him sharp analytical abilities, allowing him to make quick decisions in critical situations.

Despite being brave, Killua has had trauma related to his family, particularly due to the torture inflicted by his brother, Illumi. This trauma made him feel pressured and struggled against his family's will, until he gradually managed to free himself.

Killua's meeting with Gon during the Hunter Exam became a turning point in his life. This friendship not only helped him see the world from a more positive perspective but also gave him the courage to fight against fate and seek true freedom.
