Killua Zoldyck is the third child of Silva and Kikyo Zoldyck and the heir (former) of the Zoldyck Family. He is the deuteragonist of the series Hunter x Hunter.

Killua is introduced as a character similar to Gon: cheeky, cheerful, and full of bad ideas. However, contrasting Gon's politeness, Killua can be pretty rude to others, mostly strangers and older people. He is also one of the quickest-thinking characters and often analyzes a situation with great ease and accuracy. Despite his young age, his way of thinking, knowledge, and pragmatism give him the attitude of an adult. He is initially very confident about his abilities and able to gauge other people's abilities accurately.

A stark contrast to his best friend Gon, Killua is highly mature in both thinking and emotion. He can keep his anger in check and maintain rationality better than Gon even when facing a terrifying experience.

[Spoiler: Despite his horrendous upbringing and the torturous training his family has put him under, Killua has managed to remain generally positive and does not seem too psychologically affected by the pain he's endured.]

[Spoiler: As time passed, Killua became humble about it and no longer touted his abilities. Despite his advanced knowledge and level-headed nature, he is not very open in general. He will become very embarrassed when Gon openly calls him his best friend or compliments him about their bond.]

Character Background:

[Spoiler: Killua was born as the middle child of a family of known assassins, the Zoldycks. Showing great promise from birth, Killua followed the traditional Zoldyck training, being an assassin. He had already mastered many killing techniques at a tender age and was set to be one of the best assassins the family had ever produced. At the age of three, he started training in tailing that routinely put his life at risk.

When he was six or seven, he mastered the game of darts as part of basic training. Around the age of nine, he met and attempted to befriend the newly hired Canary (an apprentice butler of the Zoldyck Family). She thanked him for the thought, but she declined his offer to be friends due to their different status.

At an unknown point in his life, his family determined he lacked the mindset of a real assassin and had Illumi implant a special needle in his head to remodel his character through fear subliminally.

Sick of killing, at the age of 11, he rebelled against his family, injuring his mother and older brother, and ran away from home to take the Hunter Exam for fun.]

Timeline:

Hunter Exam Arc:

[Spoiler: During the 287th Hunter Exam, he met Leorio, Kurapika, and Gon during the first part. After passing all four phases, during the final phase, he encounters his older brother, Illumi Zoldyck, who is disguised as a hunter named Gittarackur.

Killua becomes afraid as Illumi questions his motives, with Killua admitting he does not want to become a Hunter but only challenges himself with the trials. Illumi threatens Killua by killing Gon if he loses his fight, causing him to surrender and return to his home.

Became unresponsive to Kurapika and Leorio's callings, he interferes with the match between Leorio and Bodoro and suddenly impales Bodoro from behind, causing himself to disqualify because of his murder.]

Zoldyck Family Arc:

[Spoiler: After Killua arrives at his home in the Kukuroo Mountain, he lets himself be tortured by his brother Milluki for three weeks. When Milluki tells him Gon, Kurapika, and Leorio are awaiting him at the butlers' quarters, and threatens to have them kill the three.

Killua is intimidated by his dad, Silva, but slowly opens up during their conversation in Silva's room. During their talk, Silva acknowledges that Killua is his person and not a mere extension of him; Silva has him promise that he will never betray his friends and lets him go.

He reunites with Gon, Kurapika, and Leorio at the butlers' quarters and leaves the house together. They agree to meet again in six months, on September 1st, in Yorknew City. Kurapika and Leorio depart that same day, while Gon and Killua stay together.]

Heavens Arena Arc:

[Spoiler: Killua confronts Gon about his plans and makes him understand he needs to train if he wants to stand a chance at landing a blow on Hisoka. They fly to Heaven's Arena, where they can teach and earn money at the same time.

They meet a fellow fighter, a young boy named Zushi, and his teacher, Wing. After reaching the 150th floor, Wing warns Killua and Gon against acquiring incomplete knowledge. To make them prepared, Wing takes him and Gond to his hotel room to teach the basics of Nen.

On the 200th floor, they encounter Hisoka and couldn't even get close to him because of his insane bloodlust. Despite his protests, Killua is unable to advance and cannot figure out why. Wing appears behind the two boys and offers to teach them the real Nen.

After learning the natural Nen, Wing started to teach them how to use the basics of Nen. Killua and Gon practiced nonstop to beat their opponents and get ready for the real world.]

[Spoiler: After receiving the secret message from the box given to Gon by his father Ging, the two decided to go to the Southern piece auction in Yorknew City to obtain the missing part of the message.]

Yorknew City Arc:

[Spoiler: At Yorknew City, Killua and Gon encountered the Phantom Troupe, having fiery battles with the members to receive the stolen items from the auction.

Later on, Killua, Gon, Kurapika, and Leorio meet up as planned. Kurapika shares his sole reason to be in the Yorknew City, to wipe out the Phantom Troupe. Killua and Gon suddenly got involved in Kurapika's plan but fell through because of the sudden interferences and the immense knowledge and strength gap against the Phantom Troupe.]

[Spoiler: On September 6th, after their battle with the Phantom Troupe, Gon finds a way to enter the Greek Island, hired by Battera as a player instead of trying to purchase the game, which Killua estimates to be likely to succeed.

During the tryouts for the Greed Island, Killua passes the test quickly while shocking the jury, Tsezguerra, by controlling the electricity at such a young age.]

Greed Island Arc:

[Spoiler: After entering the greed island, Killua and Gon started on a long and adventurous path to beat the game: Greed Island. The two decided to win the game together. However, they met Biscuit Krueger, their future Nen teacher, and became a strong trio after a short time.

Later on, Biscuit proclaimed herself as their new Nen instructor. Despite Killua's continued protests, she reveals she used to be Wing's teacher after introducing herself. Suddenly the two young rookie hunters found themselves in intense but practical training. Biscuit started to teach them the advanced Nen techniques to boost their Nen usage in a short amount of time.]

[Spoiler: When they discover it is almost New Year's Eve, Gon reminds Killua of the approaching deadline for the Hunter Exam. Killua meets Kiriko to be able to go to the exam site.

The examiner of the First Phase demands all 1489 applicants battle for two hours and bring him five badges. As soon as he closes the door, Killua proceeds to knock out all the examinees, becoming the only person to pass the 288th Hunter Exam and with no other trials.]

[Spoiler: Returning to the Greed Island, Killua meets with Gon and Biscuit to continue their adventure.

After a fierce and final battle with the terrorist group named ''Bomber'', Killua places the last card to their book and completes the game with Gon and Biscuit.
