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".
William Moulton Marston
After her name "Suprema" was replaced with "Wonder Woman," which was a popular term at the time that described women who were exceptionally gifted, the character made her debut in "All Star Comics" #8 in December 1941. Wonder Woman next appeared in "Sensation Comics" #1 (January 1942), and six months later, "Wonder Woman" #1 debuted. Except for four months in 1986, the series has been in print ever since. The stories were initially written by Marston and illustrated by newspaper artist Harry Peter. During his life Marston had written many articles and books on various psychological topics, but his last six years of writing were devoted to his comics creation.
