Menthuthuyoupi, nicknamed Yupi, is the third of the chimera ant king's Royal Guard. Mentsutsuyupi is the largest of the Royal Guards and the only non-human hybrid among them, mixed with the genes of a magical beast instead. He is the most straightforward of the royal guards and possesses a strength that comes from complete selflessness and devotion to the King. Youpi's ability allows for both bodily metamorphosis and the transformation of his own anger into pure destructive power. His Hatsu allows for him to billow large quantities of his aura into his body through En, subsequently resulting in an explosion. Youpi can use his explosive ability in conjunction with his shape-shifting ability, physically manifesting the blast's power into his own body. (Source: Wikipedia)
