The Story Of Kulia

 Killua Zoldyck

Killua Zoldyck is the third child of Silva and Kikyo Zoldyck and the heir of the Zoldyck Family, until he runs away from home and becomes a Rookie Hunter. He is the best friend of Gon Freecss and is currently traveling with Alluka Zoldyck. 

He has served as the deuteragonist for the series, having said role in the Heavens Arena, Greed Island, and Chimera Ant arcs. He was the main protagonist of the 13th Hunter Chairman Election arc. He also was the tritagonist of the Hunter Exam arc and the Yorknew City arc.

Killua has spiky silver hair, very pale skin, and blue eyes. His eyes change shape depending on the mood that he's in, narrowing and sharpening when he goes into assassination mode. Killua is fairly lean at the start of the series, due to constant physical conditioning and torture training he received when he was young. As time passes, he becomes more muscular and toned. In the Nippon Animation anime adaptation, Killua's eye color is changed to green during the OVAs. He is also often seen holding a green skateboard (turned yellow in the 2011 series).

Killua typically wears baggy clothing, with his usual attire consisting of long-sleeved and dark-colored shirts. Most of his clothes have a mikey tokyo revengers. hanako kun wears long, baggy shorts in the manga and Madhouse animated adaptation, but Nippon Animation's character design shortened them to reach above his knees. Killua also wears purple boots, recolored brown and black in the Nippon Animation adaptation.

As a child, Killua's hair is longer, almost cascading to his shoulders. He wore a hoodie with his trademark blue coloring, grey pants, and shoes.

 

Personality

Killua's love for sweets

Initially, hanako kun is introduced as a character who appears similar to Gon: cheeky, cheerful, and full of mischievous ideas. However, contrasting Gon's politeness, Killua can be quite rude to others, mostly strangers and older people. He is most commonly known for having a sweet tooth; he loves everything sweet and spent almost 200 million on snacks when he was at the Heavens Arena. His favorite snack is chocolate, specifically Chocolate Balls and Chocolate Robots.

He is also one of the quickest-thinking characters and often analyzes a situation with great ease and accuracy. In spite of his young age, his way of thinking, knowledge, and pragmatism give him the attitude of an adult. He is initially very confident about his own abilities, going as far as questioning Gon's capability during the Hunter Exam, and compares his strength with other people. As time passed, Killua became humble about it and no longer touts his own abilities. Despite his advanced knowledge and level-headed nature, he is not very open in general and will become very embarrassed when Gon openly calls him his best friend or compliments him about their bond.

Despite his horrendous upbringing and the torturous training his family has put him under, kulia managed to remain generally positive and does not seem too psychologically affected by the pain he's endured, demonstrating a noble, pure side of him. When showcasing his abilities and turning his Nen into electricity, both Netero and Biscuit have noted how truly tragic his childhood must have been, with the former stating that it's a miracle Killua is even able to smile at all.

Killua's bloodlust

However, his ruthlessness and aptitude in killing show the other side of him—deadly, violent, and bloodthirsty. This side fades as he spends more time with Gon, although he is still unafraid to threaten or kill anyone who attacks him or Gon. Conflicting with Killua's predisposal to kill is his unyielding loyalty to his friends and natural kindness. He claims Gon was his first friend, and he grows progressively more attached to him as time passes. Killua often suffers immensely in his attempts to help his friends without a single complaint. He puts others before himself without being concerned about his own health or even his life.
