12 Year Old Killua Zoldyck was created by Yoshihiro Togashi

Killua Zoldyck (キルア=ゾルディック Kirua Zorudikku) is one of the four main characters from the series Hunter × Hunter by Yoshihiro Togashi. He is twelve years old and his Nen type is Transmutation. In Sins of Our Demons, Killua is a member of The Chosen and is a recruiter for them. He was the first member of The Chosen to be shown in the comic.


Killua was born as the middle child to a family of renowned assassins, the Zoldyck family. Showing great promise from birth, Killua has already mastered many killing techniques at a tender age, and is set to be one of the best assassins the family has ever produced. Bored and tired of killing, Killua unexpectedly rebelled against his family, injuring both his mother and brother, and ran away to join the Hunter exam. He met Gon during the first portion of the Hunter Exam and became great friends.

Killua divulges that ever since his birth, he has been in constant training for the occupation of a professional assassin. Killua had spent years trying to perfect unique skills that assassins portray and possess. He is forced to battle in the Heavens Arena fighting tournament at the age of 6, which he took two years to get to the 190th floor.


From the outside, Killua seems just to be the rich boy; cheeky, cheerful, has a sweet tooth, and full of mischievous ideas. However, his ruthlessness and aptitude in killing shows the other side of him-- deadly, violent and bloodthirsty.

Having been repeatedly tortured since birth, Killua has been conditioned to possess extreme tolerance for poison, electricity and pain. He possesses extraordinary agility and strength that makes Killua a one man killing machine-- not one to be trifled with, as many of his adversaries had witnessed.

However, until recently, his greatest flaw was to fear those who are more powerful than him, one of whom is his elder brother, Illumi. Killua had been trained as an assassin by his brother to be extremely cautious that he only engages in combat provided that victory is absolutely certain. This impeded him as a Hunter, as Biscut stated more than once that victory is never certain, and that depending on the circumstances, a person has the potential to defeat a stronger opponent.

Killua struggled with these conflicting ideas during the latter half of the series, as he started to encounter stronger opponents. However, his brother's teachings remained firmly entrenched in his mind, to the point that Biscuit prophesied that he would one day abandon Gon because of this. Biscuit gave Killua an ultimatum: Defeat Shoot to claim the right to go with Gon and fight the Chimera Ants. Killua lost, and resolved to leave after Gon had recovered from his fight, protecting him in the meantime.

Finally he had to face Biscuit's prophecy when he encountered a Chimera ant while Gon (who couldn't use nen at the time) wasn't far off and had no way to defend himself. Killua made an attempt to save Gon. While fighting with the Chimera Ant, Killua is also battling his inner-self. Preoccupied, Killua is losing to the chimera ant. At the last moment, Killua realized that Illumi had implanted a needle in his brain way back in the first Hunter Exam. This needle was responsible for forcing Killua to retreat and jailed himself on his comfort zone whenever any situation would potentially endanger his life. Upon extracting the needle, Killua was freed from this restraint and gained full control of his subconscious to make his own decision whether or not to flee whenever there is a need to fight stronger opponents.


Weapons and assassination artsEdit

In first part of the series, Killua does not employ or use any weapons in combat. Instead, he relies on several assassination arts passed down to him through his family. These include adjusting his fingernails into claws and the Rhythm Echo--a motion that creates an afterimage of the body through a varying cadence of steps.

During the Greed Island story arc, Killua begins using yo-yos made of a special metal alloy in combat. The yo-yos are extremely durable and heavy, weighing 50 kilograms each. They can be used in conjunction with Killua's Nen as well. Killua is reluctant to use the yo-yos in combat thus using only his raw physical abilities in order for his opponent to know as little about his combat abilities as possible.

Nen abilitiesEdit

As a Transmuter, Killua's most efficient in changing the composition of his aura into electicity. This feat was both inspired and made possible through years of electric shock torture he received as a child for resistance training from his Older Brother.

  • Lightning Palm (雷掌 Izutsushi) The first and most basic ability Killua developed. As the name suggests, Killua is able to shock an opponent by touching them.
  • Thunderbolt (落雷 Narukami) A natural evolution of his Lightning Palm ability, Killua able to transmute his aura into a bolt of lightning. The Japanese name of the ability, Narukami, comes from the famous Kabuki play, Narukami Fudô Kitayama Zakura, in which the character Narukami transforms into a thunder god at the end of the fourth act.
  • Godspeed (神速 Kanmuru) Developed by Killua during his fight against the Ortho Siblings, Godspeed allows him to react and move his body at speeds that would normally be impossible. This ability changes Killua's aura into a field capable of transmitting all electrical impulses from his brain in a straight line directly to the part of the body he wants to use, completely bypassing his nervous system. It is made up of two parts: Raikō Sekka, the ability to move his body according to his own will, and Shippū Jinrai, the ability to sense his opponents movements and have his body react automatically.
