Izuku Midoriya entered a superpowered world without a Quirk, defying societal ridicule to pursue his dream of heroism. His relentless spirit and innate heroism drew All Might, the era’s greatest hero, to name him successor of One For All—a transferable Quirk that stockpiles energy and merges the abilities of its past wielders, granting explosive strength and agility. Through grueling preparation, Izuku earned a place at U.A. High, reclaiming the mocking nickname "Deku" as a testament to his unyielding resolve. Izuku sports dark green hair, a smattering of freckles, and a lean, muscular frame honed through training. Scarred hands and a damaged right arm chronicle his Quirk’s physical toll. His evolving hero costumes mirror his tactical growth: iron-soled boots for precision kicks during his Shoot Style era, later upgraded with technology for long-range combat, each iteration emphasizing adaptability and calculated efficiency. In the "Make It! Do-or-Die Survival Training" exercise, Izuku commanded a collapsing mall rescue, delegating roles, triaging injuries, and exploiting Ochaco Uraraka’s Zero Gravity and Momo Yaoyorozu’s creations to secure escape paths. Facing flooding chaos, he partnered with Shoto Todoroki and Katsuki Bakugo, manipulating ice and explosions to carve exits. A defining moment came when he persuaded the wounded Bakugo to accept assistance, bridging their adversarial history into collaborative respect. Relationships fuel Izuku’s journey: Ochaco offers steadfast support laced with quiet affection, while Bakugo’s childhood taunts mature into a fierce yet productive rivalry. Mentored by All Might, Izuku embraces a burden of responsibility, at times recklessly facing threats alone—a lone-wolf instinct curbed when classmates prove trust outweighs solitude. Post-graduation, Izuku sacrificed One For All to defeat Tomura Shigaraki, transitioning to U.A. instruction. Later technological strides merged mechanical augmentations into his gear, reigniting his frontline hero role. His arc—from Quirkless outlier to Pro Hero—epitomizes perseverance, self-sacrifice, and reimagining power through empathy and inventive resolve.
