All For One's Endgame If He Won (Canon-Based Analysis)
All For One (AFO) in My Hero Academia is driven by pure selfishness, megalomania, and a twisted "demon lord" fantasy from childhood comics. He doesn't care about the world, society, or even most people — he views them as disposable tools, playthings, or prizes to steal from. His core obsession is personal completion and eternal dominance, not rebuilding or conquering for any greater cause. Like Lord Shen in Kung Fu Panda 2, who seeks to rule through superior firepower to prove his worth and erase his past rejection, AFO's plans are deeply personal: rooted in ego, possessiveness over his brother Yoichi, and a desire to "have it all" without opposition. But AFO's villainy is colder — no redemption arc, just endless control.
Canon Motivations and Goals (From the Wiki)
Demon Lord Fantasy: AFO explicitly models himself after comic book villains: a supreme evil ruling through fear, while heroes cower in shadows. He declares, "This will be the story of how I became the greatest demon lord of all!" and wants a world "that exists for my sake and mine alone."
Obsession with Yoichi and One For All (OFA): Yoichi is his only "family," seen as his possession. AFO killed him in rage but spent centuries chasing OFA (which contains Yoichi's vestige) to "reclaim" and merge with him for "completeness." Stealing OFA would fuse their powers eternally, fulfilling his possessive love/hate. In his final moments, he begs Yoichi not to fade, admitting he was "nothing" without him — revealing deep loneliness beneath the cruelty.
Immortality and Possession: Groomed Tomura Shigaraki as a perfect vessel (amplifying his hatred to erode OFA's will and enable theft). In the Final War, AFO used rewinds to prime his body, planned full consciousness transfer into Tomura, steal OFA, and become an unkillable entity.
No Care for the World: Society is irrelevant — he exploits chaos, offers power manipulatively, discards allies (e.g., abandons useless followers), and thrives on fear/submission. He states things like, "My turn will never end," and envisions a "void era" where he thwarts humanity's future just because he can.
What If AFO Won? (Speculative, Grounded in Canon Statements)
If AFO succeeded — fully possessing Tomura's enhanced body, stealing OFA, merging with Yoichi — he'd achieve his "perfect" form: an immortal, omnipotent being with every Quirk imaginable, including stockpiled OFA power.
Immediate Aftermath: Eternal rule as the ultimate demon lord. No heroes left (All Might broken, Deku defeated/OFA stolen, society collapsed from war/chaos). World in perpetual fear, with AFO pulling strings from shadows or openly dominating.
Long-Term: A stagnant, hollow existence tailored to his whims. Everyone submits or dies; Quirks as currency under his control. He'd "possess" Yoichi forever, satisfying his obsession, but canon hints at emptiness — AFO needs external hatred/conflict for drive (he has none inherently), and ruling without challenge became "joyless" even in partial victories.
Not World-Building: Unlike conquerors who reform society, AFO wouldn't "fix" anything. No order, no prosperity — just endless personal satisfaction through fear and possession. It'd be a "void era" of stagnation, with humanity as fodder for his entertainment. Like Shen's cannon conquest starting a new era of peacock rule, AFO's win kicks off his eternal "turn," but it's selfish void, not legacy.
In short: Victory = god-like isolation with everything "his," including Yoichi. No grand society, just infinite dominance for a lonely, empty villain who finally "has it all" — but probably still feels incomplete, as his core is twisted neediness.
