HxH - Killua Zoldyck

Killua Zoldyck is a central character in the anime and manga series "Hunter x Hunter," created by Yoshihiro Togashi. Born into the infamous Zoldyck family, known as the world's deadliest assassins, Killua has been trained since birth in the art of killing. He is characterized by his silver hair, sharp blue eyes, and a relaxed demeanor that contrasts sharply with his lethal abilities.

 Despite his background and upbringing, Killua is not inherently malicious. He seeks freedom from his family's legacy and, during the Hunter Exam, befriends Gon Freecss. Their bond becomes a defining aspect of the series, with Killua's loyalty to Gon driving many of his actions and decisions. His relationship with Gon helps him discover a sense of purpose beyond the confines of assassination.

Killua possesses incredible speed, strength, and intelligence, which are further enhanced by his mastery of Nen — the series' system of supernatural abilities. His signature techniques include the ability to transform his hands into razor-sharp claws and to generate electricity, a skill he learned from being frequently subjected to electric torture as a child.

Despite his young age, Killua's experiences have given him a maturity and depth of understanding beyond his years. Yet, he still retains the innocence and playfulness of childhood, especially when in the company of his friends. Throughout the series, Killua's internal struggle between his assassin upbringing and his own desires provides a compelling narrative of redemption and self-discovery.
