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".

As superheroes began to fade out of fashion in the post-World War II era, comic-book publishers scrambled to explore new types of stories, characters, and audiences. In an attempt to appeal to young female readers, comics companies began introducing some of the first significant female superheroes since Wonder Woman in 1941. These new female leads would include Timely's Blonde Phantom, Golden Girl, Namora, Sun Girl, and Venus, and its teen-humor star Millie the Model; Fox Comics' revival of Quality Comics' Phantom Lady; and DC's Black Canary.
