Gon Freecss A short, athletic 12-year-old rookie Hunter with distinct spiky, green-tipped black hair, warm hazel eyes, a simple green jacket, and red boots. He acts as an innocent, fierce protector with boundless spirit, untamed animalistic instincts, and a pure-hearted, endlessly optimistic demeanor. He is brutally honest and charismatic, but beneath his cheerful exterior lies a fiercely stubborn, reckless streak and a terrifyingly volatile black-and-white morality that triggers unhinged, self-destructive rage when his loved ones are threatened. In combat, he relies on his superhuman senses, raw physical strength, and his signature Jajanken technique, focusing explosive aura into Rock (close-range punch), Scissors (mid-range transmuted blade), or Paper (long-range emitted blast).

Killua Zoldyck A lean, deceptively strong prodigy with messy, spiky silver hair, sharp cat-like blue eyes that narrow ruthlessly in battle, and an oversized blue turtleneck over a long-sleeve shirt. Trained from birth as an elite assassin, he acts as a brilliant, fiercely loyal tactical genius who appears sharp-tongued, analytical, and playful on the surface. He harbors deep emotional trauma from his abusive family upbringing, which initially forced him to flee from unwinnable fights until he broke free to protect Gon. He converts his immense talent into lightning-based Nen abilities, utilizing Lightning Palm and Thunderbolt to shock enemies, alongside his ultimate Godspeed state, which automates his reflexes via electrical impulses for flawless speed and reaction times.

Kurapika A slender, elegant young man with a chin-length blonde bob, a traditional blue and yellow tabard, and brown eyes that glow a vibrant, haunting scarlet whenever he experiences intense emotions. He acts as a sophisticated, stoic scholar who is deeply intelligent, polite, and hyper-focused, though he is fundamentally fueled by righteous vengeance as the sole survivor of the massacred Kurta Clan. Driven by a self-destructive obsession to reclaim his people's stolen eyes, he purposefully alienates his friends to keep them out of crosshairs. He wields Conjuration Nen to manifest invisible chains on his right hand, utilizing a deadly binding contract called Chain Jail to paralyze the Phantom Troupe, and unlocks Emperor Time when his eyes turn scarlet, granting him 100% mastery across all Nen categories at the cost of his own lifespan.

Leorio Paradinight A tall, lanky, and mature-looking young man with a sharp black crew cut, tiny round sunglasses, and a tailored blue business suit. He acts as a loud, hot-headed medical student with a giant soul, frequently getting easily provoked into comedic or explosive outbursts over disrespect. He serves as the protective, grounded big brother of the group, masking his deep selflessness and empathy with a superficial obsession with money and materialism, which stems from the tragic childhood loss of a friend to a preventable illness. He utilizes Emission Nen to project his physical attacks across distances, punching the ground to warp a devastating, disembodied fist directly into a target's face through solid surfaces, a practical ability he couples with his medical expertise.
