The character will get her first official introduction in December during the network's annual comic crossover event.
Caroline Dries (The Vampire Diaries) is writing the script and executive producing the series while Sarah Schechter of Berlanti Productions and Geoff Johns are also on board as executive producers. And knocking down a few outdated superhero paradigms in the process. The character is Kate Kane, a woman with a passion for social justice and a flair for speaking her mind. "In a city desperate for a saviour, Kate must overcome her own demons before embracing the call to be Gotham's symbol of hope". So instead of a Bat-man, the network is looking into the possibility of Batwoman.
Not everyone is super optimistic about the prospect of another DC x CW series, but it would make Batwoman the first gay lead character of a live-action superhero series. Batwoman was erased from the comics decades later, only to be rebirthed in the early 2000's as a homosexual hero herself.
The character will be based not on the more well-known Barbara Gordon Batgirl character, but upon the openly gay character of Kate Kane who debuted as Gotham City's Jewish, lesbian superhero in 2006. Moreover, December's crossover event, which will feature the casts of Arrow, The Flash, Legends of Tomorrow and Supergirl, will mark Batwoman's first live-action appearance ever.
Of course, the series will need to be picked up from its pilot for it to last.
With such a long career in comics, Batwoman will certainly make a great addition to the Arrowverse and could even be a gateway into Gotham City itself.
First introduced in Detective Comics #233 and created by Edmond Hamilton and Sheldon Moldoff in 1956, Batwoman has gone through two different incarnations and they're both named Katherine. The same actress will likely be the star of the new series. She appeared on The Brave and the Bold, a Cartoon Network presentation circa 2008, as well as the animated films Batman: Mystery of the Batwoman, Batman vs. Robin, and Batman: Bad Blood.
