Mei Hatsume, a student in U.A. High School’s Class 1-H Support Department, engineers cutting-edge support gear for aspiring heroes. Her Quirk, Zoom, grants telescopic vision extending up to five kilometers, enhanced by crosshair-patterned irises resembling scope lenses—a trait she employs to scrutinize her inventions and track distant objects during tests. Driven by an obsession for innovation, Mei affectionately dubs her gadgets "babies" and approaches opportunities with ruthless pragmatism. At the U.A. Sports Festival, she allies with Izuku Midoriya to leverage his visibility, later manipulating Tenya Ida into unwittingly advertising her gear to corporate scouts, underscoring her shrewd entrepreneurial instincts. Her interactions often disregard social norms, exemplified by invasive actions like prodding Izuku’s muscles during workshops, unsettling peers. Yet her collaboration with him yields critical equipment such as Air Force Gloves and Iron Soles, designed to reduce strain from his Quirk. Though her instructor Power Loader chastises her chaotic experiments, he acknowledges her technical brilliance. Post-graduation, Mei’s influence grows. She fortifies U.A.’s security during the Paranormal Liberation War and later founds Lightly Labs, a leading support-tech firm. Her matured appearance—longer hair, upgraded goggles—belies an undiminished zeal for invention. Her portfolio spans reliable tools like Hydraulic Bracers to volatile prototypes like the explosive "My Adorable Baby" robot. Embracing mishaps as iterative steps, she lives by her creed: "Failure is the mother of invention." Steampunk aesthetics permeate her designs, blending functionality with mechanical flair. Notable dynamics include a fraught rivalry with Tenya Ida, who bristles at her exploitation, and a tense camaraderie with Ochaco Uraraka, wary of Mei’s closeness to Izuku. Despite self-serving tendencies, Mei champions the Support Course’s ethos, asserting that innovation itself is heroic. Her evolution—from a single-minded tinkerer to a visionary shaping institutional security and hero tech—cements her as a linchpin within hero society, merging inventive genius with the pragmatic demands of heroism.
