Illumi Zoldyck y Hisoka

Illumi, most of the time, doesn't show many emotions. Despite his deadpan attitude, Illumi tends to speak in a cheerful and absent-minded manner. He is a cold, ruthless person and thinks only of his interests, without involving his feelings.

Illumi is expressionless, his face is like an emotionless mask. He has jet black hair, which is very long and he combs it back. His eyes are very dark.

To disguise himself as Gittarackur, Illumi uses large round-headed pins to reconstruct his facial structure, so that even his voice is unrecognizable. The pins in his chest seem to affect the muscles in his body, as he looks thinner without them.

Needles: Illumi can use large needles to change his appearance or attack. These needles can also alter another person's appearance, or control them against their will, as is the case with his Human Needle ability.

Zoldyck Transmitter: Although seen once, Illumi uses a transmitter to contact his father during murder reports.

Pain Tolerance: Illumi does not show any pain when Gon breaks his arm, and is not seen suffering from the pain afterwards either.

High Intelligence: Illumi is capable of making accurate predictions, as seen with Alluka's power, as he was able to understand the method in which Killua is able to make wishes without consequences. He also predicted Killua's movements from the moment he went to get Alluka to heal Gon.

Master Thrower: Illumi can throw multiple needles with great precision, always hitting the target even when off balance. He can even pierce through rock objects with them.

Nen
Illumi has an incredibly powerful murderous aura that makes anyone who comes near him fearful. He is a Manipulator. It is unknown how he learned Nen before becoming a Professional Hunter. He primarily uses it to alter his physical appearance, which he can do with or without his needles. When he puts Nen into his needles and throws them at a human, he is able to control their mind, or make them act in a certain way, as he did with Killua. His aura is so powerful, that if a needle with his Nen is thrown at a normal person, it can cripple them for life. Furthermore, Illumi can hide his Nen, which he does so well, that even Netero couldn't tell that Illumi was using a Nen ability on his brother.

Aura is the life force produced by all living organisms for survival. The aura of the entire body tends to flow together, producing a mass of energy. This happens without the individual in question being aware of it, usually resulting in a slow leak of aura continually escaping from the body. If one were to lose all of their aura, it would be equivalent to using up all of their life force, which would be fatal. The pores or points on the body where aura flows from are called Aura Nodes (しょうこう, Shōkō). Controlling these nodes is the first step to becoming a Nen user.

Hisoka has a harlequin-like appearance, with magician-like features. He has a painted face with a fuchsia-colored star on his cheek. Later on, these colors change: the star is bright yellow and the tear is fuchsia.

His talent and skill have made him truly self-confident. He looks out for his own interests and moves for his own benefit, thus doing what he pleases whenever and however much he wants, without following any rules or emotional ties. It seems that his only motivation is to defeat opponents chosen according to his own criteria,

Immense Strength: Hisoka is incredibly strong, ranking third in the Phantom Brigade in terms of physical strength. He can shatter rock and send a block from the Sky Arena ring flying with a single kick. As shown in the game Dodgeball, he is able to catch a Nen-enhanced ball with the destructive capability of a cannonball with a single hand. Enhanced Speed ​​and Reflexes: One of the pillars of his distinctive fighting style is his speed, paired with his similar surgical precision. He was able to easily grab hold of Togari's spinning blades, dodge Gon's continuous attacks without moving from the position he was in, and barely avoid a ball thrown by Razor. Enhanced Agility: Hisoka can attack from any position, as seen when he fought Gotoh. Due to his coordination, he can adapt to any fighting style he is faced with (an example being when he flawlessly caught the spinning blades Togari threw at him) and avoid most threats he may encounter. Enhanced Stamina: Hisoka has never been seen tired after any of his fights, even after intense physical exertion, mental strain, and the consumption of his aura.
