Mezo Shoji, a heteromorph with a tall, muscular frame, conceals his face beneath a blue mask—a choice stemming from childhood trauma when his unmasked features frightened a girl, prompting him to prioritize others’ comfort. Pale gray hair sweeps over his elongated face, partially obscuring scars around his mouth, later exposed when the mask tore during the Final War. Six powerful arms extend from his torso, linked by membranous skin, each capable of replicating sensory organs through his Quirk, Dupli-Arms. These appendages grant heightened sight, hearing, or touch, enabling reconnaissance, combat techniques like the rapid-strike Octoblow, and environmental monitoring via Octosearcher. His physical strength peaks at 540 kg of force, demonstrated when shielding civilians from collapsing structures on Nabu Island. Born into a society hostile toward heteromorphs, Shoji endured discrimination and physical abuse that left permanent facial scars. A defining childhood moment—rescuing a drowning girl with his Quirk—solidified his resolve to become a hero, shaping his selfless drive to dismantle prejudice while acknowledging such change spans generations. At U.A. High, he ranked sixth in the Quirk Apprehension Test and tenth academically, excelling in strategic scenarios like the Joint Training Battle, where he countered Pony Tsunotori’s ranged attacks, and the Final Exams, partnering with Toru Hagakure to outwit Snipe. During the Forest Training Camp, he sacrificed an arm to protect Fumikage Tokoyami from Moonfish and later evaded Dark Shadow while carrying an injured Izuku Midoriya. His protective nature extended to classmates: comforting Izuku after Katsuki Bakugo’s kidnapping, collaborating with Shoto Todoroki in Battle Trials, and teaming with Minoru Mineta and Tsuyu Asui in the Sports Festival cavalry battle. Interning under Gang Orca refined his reconnaissance skills, later deployed against Spinner in the Final War, where he briefly overpowered the villain before scaling Central Hospital. Post-graduation, Shoji emerged as the No. 9 Pro Hero, awarded the Imamura Peace Prize. His physique evolved—bulkier arms, a ponytail—mirroring his commitment to fostering societal change through gradual progress, rejecting Spinner’s extremism. His legacy centers on creating a better world for future generations, one where heteromorphs thrive free from inherited prejudice.
