By any chance anyone remember a story where izuku was hybrid or godzilla and king ghidorah where females were the one to get quirk while males don't, where his sister quirk is basically neko cat girl or whatever. It when Izuku get chase by bully fall out cliff and see godzilla skeletal head and one of ghidorah head, with head telephath as well somehow godzilla spirit sympathetic with Izuku. They grant him their power with Ghidorah like father with Godzilla mother way where Izuku gain power by jump and impale in ghidorah fang. He been asleep/hibernate till his body dna fully merge both kaiju. He wake up 16 years old have ghidorah form and godzilla form, even toothless dragon form, due to that he have spilt personality, fork tongue.
