4 Main Characters In Hunter X Hunter

Gon Freecss 

Gon Freecss is a Rookie Hunter and the son of Ging Freecss. Finding his father is Gon's motivation in becoming a Hunter. He has all the benefits granted by his status as a Hunter. He was often praised for his powers of observation, agility, and stamina. In battle, he thinks quickly for any alternative solutions and strategies. His most remarkable quality, however, is the bottomless potential he is gifted with. His Nen ability was called Jajanken.

• Rock (Enhancement): Rock is a close ranged attack, and has the highest power out of Gon's three Jajanken attacks. To perform it, Gon focuses aura in his fist with Ko, chanting as he readies the attack. If he has time to build up his Ren, the punch will be even more powerful.
• Scissors (Trasmutation): Gon's mid-ranged Jajanken attack, requires him to transmute his aura into a long blade which he extends from his outstretched middle and pointer fingers. With the advantage of surprise, it was able to cut through a defense that had been estimated to be able to counter Rock.
• Paper (Emission): Paper is Gon's long-ranged Jajanken attack. He uses his Emission skills to hurl aura from his open palm as a spherical projectile. It has less than one-fourth of the power of Rock, despite the two abilities consuming the same amount of aura.
• Limitation Transformation (Unknown): By forming a Vow, Gon was able to summon all the power he will ever have, growing to a mature age. His physical strength, Nen abilities, aura output and aura reserves increased immensely. However, the price to pay was as great as the boost. His body started to decay and fell into a coma. Despite making a full recovery, Gon remained unable to see and use aura again.

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. As a member of the Zoldyck Family, he has vast wealth at his disposal. He has been trained since birth to become a human weapon and is recognized by his family to be the most talented assassin in the entire history of the Zoldycks. He developed a series of Nen abilities in which he alters the properties of his aura to make it similar to electricity.

• Lightning Palm (Transmutation): The first ability Killua named, as well as the most basic one in his arsenal, consists in him electrocuting his opponent by touching them with both palms and pushing them back.
• Thunderbolt (Transmutation): Killua leaps into the air above the opponent and projects a bolt of lightning from his fingers, paralyzing them for a few moments and causing them pain.
• Whirlwind (Transmutation): The first core function of Godspeed has Killua react automatically to external stimuli. Killua programs his aura to send an electric signal to his muscles so as to instantly react to a threat. Concretely, this results in a drastic boost to Killua's reaction time, which has both offensive and defensive uses.
• Speed of Lightning (Transmutation): The second application of Godspeed allows Killua to retain conscious control of his movements. His running speed and jumping ability increase dramatically. He uses it primarily to cover long distances in a very short amount of time. On unfavorable terrain, Killua's speed with Speed of Lightning is approximately 240km/h.

Kurapika 

Kurapika is the last survivor of the Kurta Clan. He is a Blacklist Hunter and the current leader of the organization founded by Light Nostrade. He is a member of the Zodiacs with the codename Rat. His goal is to avenge his clan and recover the remaining Scarlet Eyes. He has all the benefits granted by his status as a Hunter. As a Zodiac, his authority in the Hunter Association is inferior only to that of the chairman herself. Being Light Nostrade's right-hand man, he had power over the clan and is now the boss of Light's new organization. The weapon that he conjures is a unique one-five chains that extend from each finger on his right hand.

• Dowsing Chain: The Guiding Ring Finger (Conjuration): Shaped like a ball and chain, Kurapika uses this frequently under normal situations, for defensive and offensive purposes. It is also useful for investigative activities, like determining the location of missing individuals and identifying if someone is lying.
• Chain Jail: The Restraining Middle Finger (Conjuration): Shaped like a hook, this very durable chain is designed to envelop and restrain Spiders. It forces its prisoners into a state of Zetsu, shutting off their aura and preventing the use of Nen abilities. Consequently, it is only possible to escape from it through brute force.
• Emperor Time: Absolute Mastery (Specialization): When Kurapika's eyes shift into scarlet, he changes from a Conjurer to a Specialist. This ability allows him to utilize all the types of Nen to 100% efficiency. However, the price to pay is considerable, as every second spent in this mode shortens Kurapika's lifespan by one hour.
• Holy Chain: Healing Thumb (Conjuration & Enhancement): Shaped like a cross, it cures wounds by drawing from Enhancement abilities. When Kurapika is in his Specialist state, it can heal serious injuries, such as a fractured arm, within seconds.
• Judgment Chain: Arbiter Little Finger (Conjuration, Emission, and Manipulation): ​The Stake of Retribution enters the victim's body and wraps around their heart. Kurapika gives the victim an order, which, if violated, results in the Stake of Retribution piercing the victim's heart, killing them. Kurapika himself has a blade wrapped around his heart, which he used to set the Limitations for the use of Chain Jail ability. Judgment Chain can only be used in conjunction with Emperor Time.
• Steal Chain: Thieving Index Finger (Conjuration): Shaped like a syringe, upon piercing the body of the target this chain drains their aura and steals one of their Nen abilities. While their aura is being drained, the target is forced into a state similar to Zetsu. The target is unable to use the stolen ability until it is returned to them.
• Stealth Dolphin: Index Finger In Emperor Time (Specialization): By activating Emperor Time, Kurapika can summon a dolphin-like construct with a syringe that is visible and audible only to himself. This construct can equip and analyze the stolen ability, informing Kurapika of its name, functions, and basic conditions. Kurapika can then use the stolen ability for himself or loan it to another person, including non-users, by stabbing them with Steal Chain.

Former Stolen Abilities

• Little Eye (Emission and Manipulation): The user launches an aura ball at a bug or any other small living being, capturing and gaining control over it. The largest creature the user can control is about the size of a hamster. The user gains knowledge of anything the manipulated animal sees or hears.
• Air Blow (Unknown): Little is known about it. The original user attempted to activate it through his left palm in order to break the guard of a Nen user who was capable of stopping bullets with his aura. It does not seem to require direct contact with the target to work.
• Erigeron (Enhancement): Kurapika transferred Bill's Nen to other individuals to awaken their Nen during the Water Divination ceremony. The ability dramatically accelerates the growth of a living being when the user brings the palms of their hands close to it.

Leorio Paradinight 

Leorio Paradinight is a Rookie Hunter and a member of the Zodiacs with the codename Boar. He is currently a medical student, with a goal to become a doctor. As a member of the Zodiacs, Leorio's authority exceeds that of most Hunters. His charisma conquered a great number of Hunters and his great popularity is also the reason he was selected as a Staff Advisor. However, Leorio's actual fighting skills are unknown.

• Remote Punch (Emission): After striking an object in his vicinity, Leorio emits his aura in a line that travels along a surface from the point of impact to a desired location. A wormhole-like circle is generated from which a fist emerges to uppercut the target, stretching far beyond the length of a normal arm.
