Gender in speculative fiction
The first known female superhero is writer-artist Fletcher Hanks's minor character Fantomah, an ageless, ancient Egyptian woman in the modern day who could transform into a skull-faced creature with superpowers to fight evil; she debuted in 1940 in Fiction Houses "Jungle Comics".
Cultural impact of Wonder Woman
Wonder Woman is a character initially created for comic books in 1941, the medium in which she is still most prominently found to this day. As befitting an icon of her status, she has made appearances in other forms of media and has been referenced and meta-referenced beyond the scope of traditional superhero entertainment. For several years in the 1950s, the only three superheroes to have their own comic book were Superman, Batman, and Wonder Woman.
