Flect Turn, central antagonist of *My Hero Academia: World Heroes’ Mission*, spearheads the global cult Humarise, driven by the Quirk Singularity Doomsday Theory—a belief forecasting humanity’s collapse through uncontrollable Quirk evolution. Deeming Quirks a genetic plague, he engineers Trigger Bombs to eradicate meta-abilities by fatally overactivating them. Cursed from birth with the uncontrollable Reflect Quirk, Flect endured a childhood stripped of human contact. Every instinctive deflection of touch alienated him—parents, friends, and lovers abandoned the boy they could never embrace. This searing isolation warped his view of Quirks into symbols of universal agony rather than progress. Even self-destruction proved unattainable; his power mirrored suicide attempts back onto him. Humarise emerged from Flect’s twisted utopian vision, uniting Quirkless followers and disenchanted meta-humans. To weaponize his crusade, he abducted scientists like Eddie Soul and Alan Kay, coercing them via familial threats to develop Trigger Bombs. Hidden across 25 cities, these devices lured heroes into traps while threatening Quirk-dependent societies. Yet the prophet of purity retained his Reflect abilities and permitted loyalists to keep their Quirks, embodying the hypocrisy festering within his revolution. In combat, Reflect rendered Flect an untouchable warlord. Attacks fueled retaliatory strikes as absorbed energy magnified his counterblows. Strategically, he orchestrated Humarise’s global network—bribing officials like Otheon’s police chief, framing Izuku Midoriya for mass murder, and manipulating Rody Soul through feigned compromise to retrieve a bomb deactivation key. His final clash with Izuku exposed unyielding fanaticism. Rejecting Midoriya’s arguments for Quirk coexistence through empathy, Flect clung to eradication as humanity’s sole salvation. The battle climaxed with Izuku’s United States of Smash overwhelming Reflect’s limits, dissipating its energy shield to reveal vulnerable flesh beneath—a mortal consumed by dogma. Humarise’s collapse sealed Flect’s fate: bombs disarmed, followers scattered, and himself imprisoned. His legacy epitomizes how societal rejection can mutate into global threat, illustrating the catastrophic potential of trauma metastasizing into apocalyptic ideology.
