There is this Fic called Denial where the MC is confused to have Powers because she beat a major Villain all by herself because of a Power Loophole and now everyone confuses her to be a Superhuman and gaining the attention of all sorts of Super Villains.
But it hasn't been updated in years so I had this idea of making a Dark continuation of those events where the MC gets into the usual "She totally has powers but not" trope but then endures so much psychological pressure she ends up manifesting powers finally but only after she gets Mind Controlled, completely shattering everyone's preconceptions as she then goes comatose.
Then the rest of the story follows the aftermath with people denying it and saying those were just *part* of her powerset, others angry they didn't just listen, another few guilty or ashamed for letting it get this far, and ending on the City being turned into a giant exclusion zone thanks to everyone turning this random girl into this big obstacle for every major Villain to topple even though she kept telling everyone she didn't have Powers.
