Gon and Killua

The Sky Coliseum is 3,250 feet tall and has 251 floors, making it the fourth tallest building in the world. Inside, thousands of fighters battle daily for the chance to climb to higher floors.[2] Fighters can fight and defeat their opponents using any method, but weapons are not allowed on the first 199 floors.[3] Fighters receive money for advancing through the first 199 floors; after reaching the 100th floor, each fighter receives a private room.[4] On the first floor, the reward is so small it would only buy a drink. On the 50th floor, fighters receive 50,000 Jenny for a victory. On the 100th floor, the reward is 1 million Jenny, and on the 150th floor, the reward exceeds 10 million Jenny. When Killua first went to the Heaven's Arena, he retired on the 199th floor and received 200 million Jenny, which he used to buy chocobots, spending all of the money.[5]

After reaching the 200th floor, fighters no longer receive money for winning battles, only glory. The use of weapons is permitted upon reaching this floor.[6] Fighters have 90 days to prepare for a battle, although it is possible to fight every day if desired. The top 21 fighters are called Floor Masters, as they control a floor between the 230th and 250th floors. Losing four fights results in disqualification, while winning 10 matches grants the opportunity to fight a Floor Master. A tournament called the Battle Olympia is held every two years on the 251st floor; the winner gets to live on that floor in an exclusive penthouse.[7]

Upon reaching the 200th floor, all fighters must know how to use Nen. If someone arrives there without knowing how to use it, other fighters will try to "initiate" them by attacking them with Nen. Those "initiated" usually suffer severe permanent injuries, even death.[8] Sadaso, Gido, and Riehlvelt are Coliseum fighters who were "initiated" and each suffered a permanent disability as a result.

Main ability: Jajanken (Rock, Paper, Scissors)

It's her Hatsū (special Nen ability), inspired by the children's game of the same name. It's divided into three attacks based on different Nen categories:
• Stone (Intensification): Gon concentrates all his aura into his fist using Ko and delivers a devastating blow at close range. It is his strongest and most reliable attack.
• Paper (Emission): Gon emits a ball of aura from the palm of his hand to attack from a distance.
• Scissors (Transmutation): Transmutes his aura into a sharp blade or energy sword connected to his index and middle fingers, capable of cutting through tough targets.

Gon is a young boy with black hair tipped with green and large brown eyes. His usual outfit consists of a green jacket with reddish trim over a black or white tank top, green shorts, and green lace-up boots.

Gon is 18 years old and 1.80 meters tall. He's an athletic, rugged, and friendly young man who's always looking for adventure. He's not very good at math, but having spent a lot of time in the forest as a child, he's very good with animals. Gon is an Enhancer, a type of person known for being simple-minded and determined. This determination and talent lead both potential allies and enemies to trust him and take his side. He has superhuman senses; Gon has a sense of smell almost like a dog's, excellent eyesight, and a very refined sense of taste. Gon wants to become a Hunter because he wants to understand the depths of an occupation that would cause a parent to choose it over being with their own child.

Claws: It can transform its fingernails into sharp, lethal claws, capable of tearing limbs apart with ease.
Extreme body control: He is able to dislocate his joints at will in less than a second to escape from restraints and can walk without making a sound.
Rhythm Echo: A footwork technique that creates multiple afterimages of itself to confuse the enemy and move imperceptibly.
Anatomical Adjustment (Shadow Step): Can move in complete silence creating multiple shadows around itself to overwhelm the enemy.

Killua is a transmuter and his nen ability is electricity, allowing him to create sparks or move very quickly to his advantage.

He always maintains an indifferent attitude, as he finds it difficult to show emotions. Despite his calm demeanor, he is incredibly loyal to his friends and is willing to risk everything to keep them safe, even if it costs him his life. However, he has a dark side.

He is also often very insecure but hides it with a cold personality; he is also very affectionate as a partner and would never leave your side.

The Zoldyck family is considered by the
Currently, the world's deadliest assassins. The family owns and lives on Mount Kukuroo, an inactive volcano in the Dentora region of the Republic of Padokia, at an altitude of 3,772 meters. Their estate is surrounded by massive stone walls and guarded by a giant dog named Mike and highly skilled martial artists. Only a few people outside the family have any idea what lies within the estate. A great many mysteries surround the Zoldyck family; a single photograph of any of its members can fetch millions.

The children are trained from birth in the art of assassination, though each family member has the privilege of choosing their specialty based on their strengths and preferences as they grow up. For example, the eldest son, Illumi, appears to be a master of disguise, while the next, Milluki, is a team mage and expert hacker. In each generation, a child prodigy emerges and is named as the heir. Currently, the heir to the Zoldyck business is Killua, one of the main characters of Hunter x Hunter, though Killua has indicated that he has no desire to inherit his family's occupation. It is believed that each member of the Zoldyck family began their training on their birthdate. The children are also permitted to use weapons (pins, bombs, yo-yos, and paper), which also adapt to their Nen abilities. Members are trained to use a special transmitter used in their assassination business... They have too much money.
