Imagine if AFO founds Anna first....
If All For One (AFO) and Dr. Kyudai Garaki (the Doctor) had captured Anna Scervino instead of the Gollini Family in My Hero Academia: You're Next, her Overmodification Quirk would make her an extraordinarily valuable (and dangerous) subject for their long-term experiments. Her power permanently boosts, modifies, or evolves Quirks in compatible individuals—pushing them to extreme, often uncontrollable levels—while causing severe backlash like seizures and pain to her, and agony (or temporary incapacitation) to incompatible people.
AFO and Garaki's history involves ruthless Quirk experimentation, including:
Creating Nomu (high-end and otherwise) by grafting multiple Quirks onto test subjects, often with heavy body modifications to make them viable hosts.
Quirk duplication and modification (e.g., engineering Decay as a one-way destructive version of Overhaul's Quirk).
Awakening or forcing Quirk evolution/Singularity-like effects through repeated exposure, stress, or artificial means.
Implanting enhanced or copied Quirks (like giving Nine a weaker All For One variant).
Long-term human experimentation to test Quirk limits, compatibility, and overload (often fatal).
Given Anna's Quirk is always active, reaches Quirk Singularity levels in the canon movie (causing widespread uncontrollable damage), and can force extreme evolutions in others, here are the most likely experiments she would endure under them:
Repeated Quirk Boosting on Nomu and Test Subjects Anna would be forced into physical contact with low-to-mid-tier villains, captured heroes, or early Nomu prototypes to amplify their Quirks massively. This could create hyper-powerful, unstable Nomu far beyond canon high-ends—potentially ones with evolved abilities that break normal limits (e.g., a strength Quirk becoming city-level destructive). Incompatible subjects would suffer agonizing pain or death, serving as data on rejection rates. Compatible ones would provide proof-of-concept for weaponizing her power.
Forced Quirk Evolution and Singularity Acceleration Since her Quirk already pushes toward Singularity (uncontrollable escalation), Garaki would study how repeated activations accelerate this in others. They might chain her to a single powerful subject (e.g., a high-end Nomu or even Shigaraki/Tomura) for extended periods, observing runaway evolution. This could yield insights into creating "ultimate" Quirks or countering Quirk Singularity in their own forces.
Quirk Factor Extraction, Duplication, or Grafting Attempts Garaki would try to harvest or replicate Overmodification itself—perhaps via surgical extraction of her Quirk Factor, or creating bio-engineered copies (similar to how he duplicated All For One for Nine or modified Decay). If successful, AFO could absorb a version to add "forced boosting" to his arsenal, or they'd implant copies into select Nomu to make them self-evolving.
Compatibility Testing and Mass Screening Large-scale human trials: Kidnapped civilians, orphans (Garaki's specialty), or prisoners would be forced to touch Anna to map compatibility rates (canon notes only ~1 in thousands are compatible). Incompatibles provide pain threshold data; compatibles become experimental boosters or new Nomu bases. This aligns with Garaki's organ/Quirk harvesting from facilities.
Backlash and User Control Experiments To mitigate her seizures and self-damage, they'd test suppressants, drugs (like Trigger analogs), or cybernetic implants. If that fails, they'd push her to total overload to study full Singularity takeover—potentially turning her into a living weapon that passively evolves nearby Quirks catastrophically.
Integration with AFO's Quirk AFO might attempt to steal Overmodification outright (if touch-compatible), or use her to supercharge his stolen Quirks stack—risking his own body destabilizing from extreme overload (similar to risks with too many Quirks). Alternatively, they'd use her on Tomura/Shigaraki to force even faster adaptation/evolution during his growth.
In short, Anna would be treated as a high-priority "Quirk amplifier factory"—kept alive but in constant torment, isolated except for handlers, and subjected to endless, unethical trials to push Quirk science further toward AFO's domination goals. Her fate would likely be worse than under the Gollini Family, as AFO/Garaki lack even the superficial "family" pretense and view people purely as tools or data. Canon parallels her to Eri (captive for Quirk exploitation by organized villains), so the horror would echo that arc but on a potentially larger, more apocalyptic scale given her Singularity-level potential.
