About
Menthuthuyoupi is the third and physically strongest of the Royal Guards, a towering, shape-shifting Chimera Ant who fights with brute force rather than cunning. Born without the elegance of Pitou or the intellect of Pouf, he was forged for one purpose: to protect the King with everything he has. He is also, paradoxically, the most honest of the three — the first to admit a mistake, the first to acknowledge an opponent's strength, and the only one who never lies, even to himself.
During the Palace Invasion, his duel against Morel, Shoot, and Knuckle pushes him through a transformation no other Royal Guard undergoes: he begins to feel anger, then frustration, then — for the first time — a flicker of respect for the humans who refuse to give up against him. By the time he is summoned to Meruem's side, Youpi has changed. When he and Pouf finally surrender their bodies and Nen to the reborn King, it is not out of fear or despair — it is the only honest gift he has left to give.
Abilities
Metamorphosis
Freely reshapes his body — growing wings, extra arms, blades, or weapons of pure aura — letting him adapt to any opponent and any distance in an instant.
Rage Incarnate
When his frustration peaks, his aura erupts into a monstrous face on his back that lashes out independently, multiplying his destructive output.
Enhancement Nen
His natural category lets him reinforce his body to an absurd degree, shrugging off blows that would level most Hunters and striking with continent-shaking force.
Flight
By sprouting wings from his back, he can pursue fleeing enemies through the air and dominate any battlefield from above.
Notable battles
Youpi's defining clash is the long, grinding duel in the central stairwell of the Palace, where he fights Morel, Shoot, and Knuckle at once. He beats them back again and again — yet he is the one who walks away changed, having admitted that their refusal to surrender is something his raw power cannot break. Afterward, summoned by the wounded King, he gives his body and Nen to the reborn Meruem alongside Shaiapouf — a final act of loyalty that costs him his life, taken by the same Rose poison that claimed his King.
