CW is currently developing a TV adaptation of Batwoman and it is set to be the first live action superhero series with an openly gay lead character.
When Batwoman was introduced in the 1950's she was a love interest of Batman. The purpose of her character was to prevent any further questions of Batman's sexuality because many people thought he was gay. Then in 2006 she was reintroduced as Kate Kane, an openly gay woman.
The show describes Kate Kane as an "out lesbian and highly trained street fighter primed to snuff out the failing city's criminal resurgence. She is armed with a passion for social justice and a flair for speaking her mind". The show will focus on her "overcoming her own demons" before emerging as a hero in Gotham City.
