Ruby Rose Is An 'Emotional Wreck' as She's Cast as Lesbian 'Batwoman' for The CW

The CW announced Tuesday that the actress has been cast as Kate Kane, AKA Batwoman, in the network's Arrowverse, with a series of her own in development.

Rose, who is best known for her role on "Orange is the New Black," will be introduced during the network's annual crossover event this winter. Her version of Batwoman will be an out lesbian, while Rose herself identifies as gender fluid.

"The Bat is out of the bag and I am beyond thrilled and honored," Rose herself exclaimed on Instagram. "I'm also an emotional wreck.. because this is a childhood dream. This is something I would have died to have seen on TV when I was a young member of the LGBT community who never felt represented on tv and felt alone and different. Thank you everyone. Thank you god."

After the crossover event, the plan is for her to have her own series for the 2019-2020 season from writer/director Caroline Dries.

"Armed with a passion for social justice and a flair for speaking her mind, Kate Kane soars onto the streets of Gotham as Batwoman, an out lesbian and highly trained street fighter primed to snuff out the failing city's criminal resurgence," reads the official logline for the show. "But don't call her a hero yet. In a city desperate for a savior, Kate must overcome her own demons before embracing the call to be Gotham's symbol of hope. Based on the characters from DC."

One of the show's executive producers, Sarah Schechter, teased the series to TooFab at San Diego Comic-Con.

"I am so excited," Schechter said. "She will be making an appearance in the cross-overs. Caroline Dries, who is the creator, is so incredibly talented. The sides are fantastic, I cannot wait. She's a total badass and I think it's gonna be -- in the sliding scale -- I definitely think it's closest to 'Arrow' in terms of darkness and intensity and it's gonna be so much fun."

The crossover event will air in December on The CW.
