It's only been a few days since the CW has announced that Megalodon and John Wick: Chapter 2 actress Ruby Rose had been cast in the role of Kate Kane/Batwoman, but the news was so massive, so popular that it took the entire world by storm. As the first lesbian actor to portray a gay superhero in a leading role, the casting of Rose is an unprecedented event that's been a long time coming.After fans and critics welcomed the spot-on casting, the leading man of the Arrowverse himself and Green Arrow actor Stephen Amell welcomed Rose to the CW superhero family with a brief yet telling message on Twitter. "Hey @RubyRose -- Welcome!!" the actor wrote. "It’s characters like Batwoman that will carry our Universe into the future. See you soon!"RELATED: Ruby Rose Gets Emotional Discussing Impact of Her Batwoman Role

With his tweet, Amell not only once again proves that he is a class act, but also that he recognizes the importance of the character to the world at large. The Arrowverse has been a breeding ground for new superheroes of all kinds, and Batwoman is easily the biggest, most diverse DC character to make the jump from comics to television.

Furthermore, with rumors circulating that Arrow's seventh season could be approached as the series' last, it's possible that Amell is getting ready to pass the torch of the Arrowverse to its next leading character.

The hope is for Rose to star in her very own Batwoman solo series after an introductory guest stint in this year's highly-anticipated Arrowverse crossover event -- but it's not a done deal yet. While Batwoman will appear in the crossover for sure, her own series has yet to be given a green light. But fans shouldn't worry too much, because with the way Ruby Rose's casting has been received, it sure seems like the future of Batwoman is a bright one.
