okay, okay, hear me out:
what if the boy who lived was the girl who lived? scruffy tomboy harriet “call me Harry” potter, getting extra rubbish from the Dursleys both from being a girl and being the wrong kind of girl
and absolutely nothing in the entire 7-book series changes except for pronouns. because girls can be brave and imperfect and angry and sulky and loud just like boys can.
(except a girl harry would room with Hermione Granger and the Patil twins instead of Ron and Sean, but that’s literally the only thing I can think of that might change)
