If All For One (AFO) won, secured his ideal vessel (Shigaraki or another), conquered Earth, and then reached beyond Earth to expand into the universe, the consequences would spiral far beyond My Hero Academia’s scope. This scenario pushes his ambition from a global domination goal to a cosmic one, which dramatically escalates both the themes and the stakes.

AFO's Victory on Earth

With control of his perfect vessel, AFO would now have absolute dominance over quirks, collecting an unstoppable arsenal of powers.

Hero resistance would collapse, as his mastery of Decay, regeneration, strength, and countless quirks make him a literal godlike entity.

Quirk society would fully dissolve, replaced by a dictatorship centered around AFO as the sole authority figure. The concept of "heroes" would be erased, rebranded as "tools of his empire."

Expansion Beyond Earth

Once Earth is secured, AFO's ambitions would logically turn outward:

Resource Exploitation: Space would become a supply of materials, energy, and potential colonies to fuel his regime.

Universal Conquest: His psyche thrives on domination. After Earth, he can only validate his existence by spreading control further, seeking intelligent life throughout the galaxy.

Quirk Supremacy: If alien species exist, he would attempt to harvest or adapt their powers into his own quirk arsenal, evolving himself past human limits into a universal overlord figure.

Themes and Symbolism

This direction transforms All For One from a human tyrant into a cosmic archetype of evil.

Quirks as Infinite Hunger: His ability represents endless acquisition—a parallel to imperialism and unchecked consumption. Extending into the universe symbolizes how greed knows no bounds.

Loss of Humanity: By the time he conquers Earth, his motivations drift from societal control into existential domination. His identity becomes “control for control’s sake," no longer tied to human desire but to an inhuman hunger for infinity.

Heroism Without Borders: If resistance survives, heroes would have to evolve into something akin to interstellar defenders, introducing a mythic, almost Superman-level scale to My Hero Academia’s central conflict.

Potential Outcomes

Universal Empire: AFO reigns like a galactic emperor, rewriting morality, justice, and freedom across worlds.

Inevitable Rebellion: Just as he faced resistance on Earth, intelligent life elsewhere would eventually resist, setting the stage for an even greater "symbol of peace" figure to rise against him.

Paradox of Power: The more vast his control becomes, the more unstable it is. Managing entire civilizations across galaxies increases the risk that his empire collapses under its own weight.

Godhood vs Mortality: With infinite quirks and power, AFO would essentially ascend to a deity-like status—but his very human traits (ego, paranoia, fear of irrelevance) could still spell his downfall.

Narrative Shift

All For One (AFO) sought to create powerful vessels—subordinates molded or engineered to serve as hosts, tools, or possible successors to carry on his ambitions. Both Kai Chisaki (Overhaul) and Toya Todoroki (Dabi) were involved in versions of these plans, but both ultimately became failed vessels. Here’s a focused analysis, drawing directly from the detailed file provided.

All For One’s Vessel Strategies

AFO’s core vessel plan was to ensure his legacy and domination would persist, often by manipulating or “raising” gifted individuals to serve his agenda, or—if their Quirks and bodies were suitable—serve as hosts for his own power. This process included both careful psychological grooming and direct Quirk experimentation.

Overhaul (Kai Chisaki)

Background as a Vessel: Raised in an orphanage owned by Kyudai Garaki (AFO’s chief scientist), Chisaki was among children considered as potential hosts for AFO. His destructive perspective on Quirks (believing them to be a disease) and his Overhaul Quirk’s incredible reconstructive and destructive potential marked him as a prime candidate.

AFO’s Direct Intervention: AFO duplicated Overhaul’s Quirk (stripped of its restoration aspect) and gave this copy to Tenko Shimura (later Tomura Shigaraki), which would evolve into Decay. Overhaul himself was manipulated but never became a true vessel, instead pursuing his own plans for power via Eri and Quirk-destroying bullets, showing a dangerous independence.

Failure Reasons: Overhaul’s ideology and trauma isolated him, and he was unable to submit to, or be controlled by, AFO. He prioritized his own plan to restore the Yakuza and monopolize the Quirk market rather than work as AFO’s vessel. Eventually, his defeat, the loss of his arms (and Quirk), and complete psychological breakdown rendered him useless to AFO’s original designs.

Dabi (Toya Todoroki)

Background as a Vessel: Toya was “rescued” after his near-death experience by AFO and Kyudai, who rehabilitated and attempted to groom him into a subordinate. Physically rebuilt and emotionally fragile, Dabi was recognized as having extraordinary potential due to his powerful (and unstable) blue flames.

AFO’s Direct Intervention: Kyudai anticipated Toya would not survive long post-coma, but Dabi’s psychological grudge kept him alive. Despite attempts to brainwash and manipulate him as a weapon/subordinate, Toya rejected their control, insisting no one but his father (Endeavor) could be his guide. He fled, and AFO classed him as a failed project.

Failure Reasons: Dabi ultimately became self-directed, fixated on personal vengeance against Endeavor and the hero system rather than serving anybody’s ambition. His instability, obsession, and disregard for AFO’s actual plans made him impossible to control. He did not care for the broader goals of the League or AFO, only for hurting his family.

Pattern of Failure

Autonomy: Both Overhaul and Dabi had strong, trauma-driven personal agendas which prevented complete subjugation or loyalty to AFO.

Lack of Psychological Hold: AFO’s methods failed to instill sufficient mental control; Overhaul’s grandiosity and Dabi’s obsession led both off-script.

🔹 AFO’s Vessel Project: Full Plan

1. Foundation – Doomsday Theory & Early Experiments

Inspired by Kyudai Garaki’s “Quirk Singularity / Doomsday Theory.”

AFO realizes Quirks will outgrow human bodies.

Begins cultivating potential vessels to house multiple Quirks without breaking down.

2. Historical Roots

Birth of Zen (All For One) and Yoichi.

AFO develops obsession with “ownership” and creating a perfect successor.

Steals, experiments, and cultivates hatred as fuel for a future vessel.

3. Prototype Candidates

Number 6 → “Blank slate,” molded by AFO under guise of O’Clock. Served as a long-term test of psychological grooming, quirk augmentation, and body modification.

Nine → Engineered with a copy of AFO’s Quirk; genetic instability shows vessel limitations.

Overhaul (Kai Chisaki) → Decay copy extracted from Overhaul’s Quirk, stripped of restorative ability, became Tenko/Tomura’s Decay. Overhaul himself viewed as a “useful piece,” but not viable as vessel.

Dabi (Toya Todoroki) → Rescued from death and rebuilt with regenerative tissue. Intended as spare vessel, but rejected AFO’s conditioning due to obsession with Endeavor. Escaped.

Nomu & Trigger Experiments → Villain Factory, bioengineering, Quirk-boosting drugs — all stepping stones in testing compatibility and durability.

4. Main Vessel Development – Tenko Shimura

Quirkless child (original factor stolen by AFO).

Gifted incomplete Decay quirk.

Groomed into Tomura Shigaraki, “Symbol of Fear.”

Carried psychological conditioning (hands of his family, hatred cultivation).

Reinforced through bioengineering, combat training, and Quirk stacking (planned AFO transfer).

5. Failures, Lessons & Refinement

Each prototype revealed limits:

Number 6 = unstable psyche.

Nine = genetic degradation.

Dabi = uncontrollable will.

Overhaul = flawed Quirk transplant.

Lessons led to focus on hatred, willpower, and body reinforcement as key vessel requirements.

6. Execution of Final Plan

AFO duplicates his own Quirk, stores a copy with Garaki.

Waits for Tomura to reach maturity in both will and body.

Intends to overwrite Tomura with himself (true vessel transfer).

Backup contingencies: Gigantomachia, Nomu, Yuga Aoyama as mole.

7. Endgame

Tomura becomes perfect fusion: Symbol of Fear + Symbol of AFO.

Vessel capable of enduring Quirk singularity.

“....leave us.” Waving his hand to the white haired boy who had brought in the man he served, the white dragon couldn’t help but bow to the Symbol of Evil. A man who exceeded all expectations and his predictions... A man who he found joy in existing again- small spats of boredom sometimes reared it’s ugly head, but he felt free.

More than he had than under the lock and key of the commission.
