Ruby Rose was recently cast as The CW's Batwoman and she's been welcomed to the Arrowverse with open arms. The internet has had a somewhat mixed reaction to her casting, though, there seems to be more excitement than there are those who disagree with the decision to bring Kate Kane into this universe. Now, Arrow star Stephen Amell has welcomed his fellow DC star into the fold.

Stephen Amell was the first star of The CW's corner of the DC universe which, in the years since Arrow debuted, has become wildly successful. The Arrowverse now includes the likes of The Flash, Supergirl and Legends of Tomorrow. Black Lightning is also on the network but hasn't been brought into the same universe just yet. But with Amell being the first hero to kick things off, it seems fitting that he was the one to welcome Ruby Rose as Batwoman. Here's what Amell had to say on Twitter.

"Hey @RubyRose, Welcome!! It's characters like Batwoman that will carry our Universe into the future. See you soon!"

Batwoman will be the first ever out LGBTQ superhero to lead a comic book TV show. That is, assuming Batwoman gets picked up to series. The show is currently being developed by Arrowverse architect Greg Berlanti and Caroline Dries, known for her work on The Vampire Diaries. Though, with Ruby Rose on board to play the Gotham City hero, it seems highly likely The CW will at least give the show a shot for one season.

As for Ruby Rose, she's a star who is very much on the rise. Her previous credits include Netflix's Orange is the New Black, as well as movies like xXx: The Return of Xander Cage and John Wick: Chapter 2. Rose is also starring alongside Jason Statham in this week's giant shark flick The Meg. Rose has been thrilled ever since the casting was announced. She is, herself, an out lesbian and very outspoken member of the LGBTQ community. Once the news was made public, Rose took to Instagram to explain how much the opportunity means to her, calling it a childhood dream.

"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. 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."

The Arrowverse crossover event is set for December and that's where Ruby Rose will make her debut as Batwoman. This will mark the character's first ever appearance in live-action. Though, she has been featured in several DC animated shows and movies previously. Assuming that goes well, it will pave the way for the Batwoman series, which may begin filming in the spring, positioning the show for a fall 2019 debut.
