Gon Freecss is a cheerful boy with spiky green hair, big brown eyes, and a lean, athletic build, usually dressed in a green jacket and shorts. Optimistic, kind-hearted, and fiercely determined, he’s loyal to his friends and faces every challenge with reckless enthusiasm and pure-hearted curiosity.

Killua Zoldyck is a slender, agile boy with messy silver-white hair, sharp blue eyes, and a pale complexion, often wearing dark, practical clothes that suit his assassin background. Cool-headed, witty, and fiercely loyal, he’s a natural prodigy who balances ruthless efficiency with a soft-hearted loyalty to his friends—especially Gon—while gradually shedding his family’s cold, lethal upbringing.

Leorio Paradinight is a tall, lanky young man with dark hair, a sharp nose, and a lanky frame, usually dressed in a suit or formal attire that contrasts with his loud personality. Hot-tempered, ambitious, and deeply caring, he’s driven by a desire to become a doctor and support those in need, while remaining a fiercely loyal—if often comically frustrated—friend to Gon and the others.

Kurapika is a slender, elegant young man with short blonde hair, sharp gray eyes that turn scarlet in rage, and a refined presence, often dressed in formal or stylish attire. Calm, highly intelligent, and fiercely determined, he is driven by a deep thirst for revenge against the Phantom Troupe while remaining a loyal, strategic, and principled ally to his friends.

Hisoka is a tall, lean, and muscular man with pale skin, wild pink hair, golden eyes, and distinctive star-and-teardrop face paint, usually dressed in a flamboyant, card-themed outfit that matches his jester-like appearance. Playful, sadistic, and dangerously unpredictable, he lives for the thrill of battling strong opponents—especially Gon—approaching every fight with a twisted sense of fun and a chilling, obsessive hunger for worthy prey.

Illumi Zoldyck is a tall, slender man with pale skin, long straight black hair that partially hides his face, and blank, doll-like black eyes that rarely show emotion, usually dressed in dark, formal clothing. Cold, calculating, and utterly ruthless, he is a master assassin who manipulates others with calm precision, showing a twisted, controlling loyalty to his family—especially toward his younger brother Killua—while remaining almost completely devoid of empathy or warmth.
