Mezo Shoji, a heteromorphic student, possesses a tall, muscular frame and pale gray hair obscuring much of his face, perpetually hidden beneath a blue mask stretching from below his eyes to his neck—a shield forged from childhood ostracization due to his mutation-type Quirk. After his appearance once frightened a young girl, the mask became both armor and symbol against societal prejudice. His Dupli-Arms Quirk manifests as tentacle-like limbs tipped with sensory organs, surpassing natural human limits in strength, hearing, and vision. These replicated senses detect imperceptible threats, from invisible foes to subtle vibrations, while his appendages deflect attacks and protect allies. During the Nabu Island mission, Shoji’s instincts surge as he intercepts debris from Nine’s onslaught, sheltering Mahoro and Katsuma Shimano. Collaborating with Mashirao Ojiro and Kyoka Jiro, he pins Nine momentarily, enduring searing laser strikes before succumbing—a testament to his tenacity. Shaped by years of alienation, Shoji channels empathy into action, eschewing material comforts to challenge biases against heteromorphs. He bears classmates to safety in the Forest Training Camp’s chaos and clashes with Spinner in the Final War, his mask ripped away to expose scarred, elongated features. Even beyond battle, vigilance defines him. In *School Briefs*, he curls a tentacle to barricade Minoru Mineta from encroaching on Mina Ashido. Post-graduation, his ascent to No. 9 Pro Hero and the Imamura Peace Prize cement his legacy as a bridge toward societal acceptance. Shoji merges brute force with precision, channeling 540 kilograms of crushing power and parrying lethal assaults through heightened reflexes. His tactical mind unravels Quirk mechanics, like Mr. Compress’s marble traps, while an unflappable demeanor steadies allies—proving that beneath the mask and myths, resolve transcends appearance.
