Halloween // Ideas for Female Hero Costume (real or fictional)

I’m going to a women only Halloween party where the theme is female heroes, real or fiction. A little about me for relevance, I’m an attorney, I’m extremely goofy and immature, I’m known for my over the top costumes. My list is narrowed down to: RGB (but hysterically slutty), Jane Fond (but in jazzercise form), Erin Brockovich, Jane Goodall, Rosie the Riveter.

I like my list, but there is a part of me who wants to be someone who fits the theme, but whom nobody would ever think of. Ideas?
