Tomura Shigaraki, born Tenko Shimura, emerged from a family fractured by generational strife. His father, Kotaro Shimura, inflicted relentless abuse on him, driven by bitterness over being abandoned by his own mother, the hero Nana Shimura. Tenko’s latent Quirk, Decay, erupted during his youth, annihilating his sister, mother, grandparents, dog, and ultimately Kotaro. Stranded and shattered, he was ensnared by All For One, who engineered the massacre to forge him into a weapon. The villain gifted Tenko embalmed hands from his slain family—morbid relics he wore as visceral anchors to his rebirth as Tomura Shigaraki. Early in his villainy, Tomura embodied volatile impulsiveness, lashing out with childish tantrums and an obsessive drive to dismantle hero society. His erratic leadership of the League of Villains leaned heavily on All For One’s counsel until pivotal conflicts—against the Meta Liberation Army and Shie Hassaikai—sparked maturation. Conquering Re-Destro cemented his authority as Grand Commander of the Paranormal Liberation Front, uniting disparate factions under a singular vision of annihilation. This ascent marked his transition from pawn to strategist, shedding reliance on his mentor’s oversight. His physical form mirrored ideological shifts. Initially adorned with fourteen preserved hands—trophies of trauma—he gradually shed them through battle, retaining only his father’s severed hand as a face-concealing mask. All For One’s Quirk grafts later warped his body: muscles swelled, finger-like protrusions erupted across his skin, and Quirk Singularity strains ravaged his frame. These mutations symbolized both his escalating power and the internal battle against All For One’s lingering influence. The Decay Quirk enabled disintegration via five-fingered touch, later scaling to obliterate entire cities. Inheriting All For One multiplied his arsenal, yet psychological fissures persisted—repressed memories of his family’s deaths and a subconscious yearning for rescue. This fragility clashed with Izuku Midoriya’s empathy during their final confrontation. Their struggle spilled into the vestige realm, where Midoriya targeted Tomura’s buried humanity, fracturing All For One’s grip and hastening his corporeal collapse. Tomura’s bonds defied simplicity. He shielded League members like Himiko Toga and Twice as a self-made family, gradually valuing loyalty over initial apathy toward Stain’s disciples. His relationship with All For One teetered between twisted mentorship and parasitic control, culminating in Tomura defiantly seizing autonomy. Framed by systemic neglect and hero society’s failings, his arc embodies cyclical trauma—a product of abuse, grooming, and the voids left by those sworn to protect.
