On Wednesday's broadcast of "The Tonight Show", the 32-year-old Australian actress revealed just what it meant to be cast as the first openly gay superhero.
A new masked vigilante is making her way to the CW.
"The Bat is out of the bag and I am beyond thrilled and honored". "I'm also an emotional wreck. because this is a childhood dream".
"I feel like the reason I kept getting so emotional is because, growing up watching TV, I never saw somebody on TV that I could identify with, let alone a superhero", Rose said, explaining that since the casting she's been tearing up when she talks about it. "Thank you everyone. Thank you god".
Batwoman, aka Kate Kane, first appeared in Detective Comics in 1956.
Rose will debut as the character during the network's annual superhero crossover event in December. Should her Batwoman series get picked up, we'll be seeing her in action during the 2019-2020 season.
Per the logline, as quoted by the magazine: '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'. She's even served as the primary featured hero for Gotham City in Detective Comics while Batman wasn't in the picture.
