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".
Batman (TV series)
By season three, ratings were falling and the future of the series seemed uncertain. To attract new viewers, Dozier opted to introduce a female character. He came up with the idea of using Batgirl, who in her civilian identity would be Commissioner Gordon's daughter, Barbara, and asked the editor of the Batman comics to further develop the character (who had made her debut in a 1966 issue of "Detective Comics"). To convince ABC executives to introduce Batgirl as a regular on the show, a promotional short featuring Yvonne Craig as Batgirl and Tim Herbert as Killer Moth was produced. Batgirl was the first female superhero to appear in an ongoing capacity on television. The show was reduced to once a week, with mostly self-contained episodes, although the following week's villain would be introduced in a tag at the end of each episode, similar to a soap opera. Accordingly, the narrator's cliffhanger phrases were mostly eliminated, most episodes ending with him encouraging viewers to watch next week.
