Izuku Midoriya, born without a Quirk in a superhuman society, defied societal ridicule with his steadfast dream of heroism. His destiny shifted when he inherited the transferable Quirk One For All from All Might, unlocking immense power and dormant abilities like Blackwhip and Float. This newfound strength secured his place at U.A. High School, where he honed his skills amidst physical trials and external threats targeting his legacy. In *World Heroes’ Mission*, Izuku joins a worldwide strike against Humarise, a terrorist faction deploying Trigger Bombs to eradicate Quirk users. Clad in a black stealth suit with teal-green accents and reinforced gear from the World Heroes Association, he infiltrates Otheon to dismantle their operations. A chance encounter with courier Rody Soul—who unknowingly holds a briefcase with bomb-disarm data—pulls Izuku into a deadly conspiracy. Framed for mass murder by corrupt officials, he evades capture using his Quirks and combat prowess, shielding Rody while racing to thwart Humarise. Izuku’s empathy shines through his protective alliance with Rody, prioritizing the reluctant ally’s safety even under duress. He adapts swiftly in crises, deploying Blackwhip to escape authorities and battle Humarise agents. Facing Humarise’s leader Flect Turn—whose Reflection Quirk repels assaults—Izuku deciphers his opponent’s weaknesses and channels One For All’s full might, overwhelming Flect with unyielding force. This tactical triumph, paired with Rody’s successful disarm code activation, halts global annihilation. Post-mission, Izuku temporarily abandons U.A. to shield peers from One For All’s hunters, later reuniting with allies to confront Tomura Shigaraki and All For One. His climactic clash with Tomura costs him One For All, reverting him to Quirklessness until advanced technology restores his heroic capacity. His appearance—marked by green hair, freckles, and Quirk-induced scars—mirrors his evolution, with hero costumes adapting to combat demands, including reinforced boots and long-range support gear. Throughout his journey, Izuku exemplifies selfless resolve, risking himself to safeguard others. His growth from a determined Quirkless outlier to a compassionate strategist redefines heroism through empathy, inspiring allies like Rody to embrace courage beyond conventional power.
