Minoru Mineta trains as a hero in U.A. High’s Class 1-A, distinguished by his short stature, round head, and grape-like clusters of dark purple hair. His initial costume combines a purple mask, yellow cape, and white pants with purple accents, later upgraded with tactical armbands and headphones. Though he gains height and faint stubble by the Final War, he remains shorter than classmates, retaining a slightly stocky build. Notorious for his timid demeanor and crude humor, Minoru often voices inappropriate fantasies, provoking physical retaliation from peers like Tsuyu Asui. Yet he displays flickers of maturity, apologizing for hurtful comments and consoling Izuku Midoriya during public scrutiny. Academically, he defies expectations, ranking ninth in class midterms. His *Pop Off* Quirk produces adhesive scalp spheres for trapping foes or shielding allies, with techniques like *Grape Rush* evolving through internships under The Lurkers. Overuse initially risks scalp injury, though training mitigates this. Growth punctuates his arc: at U.S.J., he conquers panic to collaborate against villains, while during the Final War, he sacrifices his Quirk to protect Fumikage Tokoyami from All For One. Post-graduation, he ranks as Pro Hero No. 108, balancing persistent cheekiness with hardened resolve. Relationships oscillate between camaraderie and friction—bonding with Denki Kaminari over humor, clashing with Momo Yaoyorozu over unwelcome advances, and respecting Izuku’s idealism. Tsuyu alternates between tolerating and disciplining him. Adopting the hero name *Grape Juice*, he initially seeks fame but gradually embraces selflessness, leveraging tactical wit against threats like Gigantomachia. Trauma sharpens his purpose: witnessing hero deaths and Yuga Aoyama’s betrayal fuels his courage. Though flaws linger, his journey from comic relief to strategic ally underscores a latent commitment to heroism’s core ideals.
