Neito Monoma, the Phantom Thief, studies in U.A. High School’s Class 1-B. His blond hair falls in deliberate bangs over his right eye, framing periwinkle-blue irises and an ever-present smirk. A black tuxedo-style hero costume features a belt with three clocks—originally tracking his Quirk’s time limit but later exposed as a tactical ruse. Post-graduation upgrades include clock-patterned gloves and earrings, echoing his affinity for calculated deception. Theatrically antagonistic toward Class 1-A yet fiercely loyal to 1-B, Monoma’s rivalry stems from envy of their public acclaim after the U.S.J. Incident. He mocks their setbacks while championing his classmates, masking an inferiority complex born from his Copy Quirk. This ability demands physical contact to replicate others’ powers for ten minutes, holding up to four at once—a reliance on others that clashes with hero society’s glorification of individuality, deepening his self-view as a perpetual “side character.” Beneath his abrasive facade lies sharp strategy and empathy. He orchestrates Class 1-B’s observation tactics during the U.A. Sports Festival’s obstacle race and consoles peers like Setsuna Tokage post-defeat. His perceptiveness catches Ochaco Uraraka’s subtle maneuvers against Katsuki Bakugo, unnoticed even by pros. Collaborative cunning shines in the Joint Training Arc, where he mimics Uraraka’s voice alongside Hitoshi Shinso to ensnare Izuku Midoriya, exemplifying psychological warfare mastery. Monoma’s arc culminates in the Final War, confronting self-doubt to become pivotal. Copying Kurogiri’s Warp Gate and Shota Aizawa’s Erasure Quirk, he disperses combatants nationwide while stifling Tomura Shigaraki’s power. Initial hesitation yields to resolve, securing him a U.A. statue and the No. 10 Pro Hero rank post-graduation—a testament to his evolution from self-declared supporting act to acknowledged hero. Childhood mockery over his Quirk’s perceived weakness forged his drive to excel through unorthodox means, like provoking rivals to galvanize Class 1-B. Spin-off media spotlights his scripting and starring roles in class plays, blending dramatic flair with teamwork. Moments shielding Eri during crises reveal a protective tenderness often obscured by his performative bravado. Relationships balance friction and camaraderie. Itsuka Kendo counters his theatrics with pragmatic restraint, while Hitoshi Shinso shares a bond over undervalued Quirks. Though he ridicules Class 1-A, he respects their prowess as catalysts for his class’s growth. His dynamic with Katsuki Bakugo wavers between taunts and tacit acknowledgment, mirroring his grasp of heroism’s competitive core.
