A League-affiliated villain targets Y/N (maybe seeing them as a rising hero or personal grudge) with a gender-altering quirk meant to humiliate/disrupt. Y/N transforms mid-battle or rescue, semi-permanent until the villain’s defeated or quirk wears off slowly. Media blows up (“Hero Y/N’s Shocking Transformation!”), forcing Y/N to keep fighting while adjusting—new suit fittings, public scrutiny, dysphoria in interviews.
