In the world of My Hero Academia, Quirks can come in all kinds of weird and unique forms, but by far one of the most powerful in the series is Rewind, an ability possessed by a young and innocent girl by the name of Eri. As the name implies, this Quirk allows Eri to reverse a person's physical state by making contact with them, and needless to say, this has resulted in many characters, heroes and villains alike, wanting to get their hands on her to make use of it.
