I believe the CW Batman is gonna appear either season finale or next season on Batwoman. Just like Superman didn’t appear right away on Supergirl.
Didn’t Stephen Amell joke about Jensen Ackles being on set fir the crossover to play Batman? It would be awesome if he wasn’t joking.
I’m just glad DC/WB is loosening their grip enough to allow the idea to even be considered. Two or three years ago, having a marquee character like Batman show up on a television show was not possible because they saved him for films. But I think they’re finally realizing that their films with the exception of Wonder Woman, have not been well-received, but the TV side has been crushing it, so maybe they don’t want to hamstring themselves any further and just let TV use these characters alongside the film counterparts.
Obviously, a CW Batman would be very welcomed addition to the Arrowverse. With Superman already established, we might actually get a true “world’s finest” team up. And, of course, the inevitable Green Arrow/Batman smack-down would rock the Arrowverse.
If Batman appears anywhere it should be on Titans. Arrowverse will make some sort of PC statement about him, eventually…
Theoretically Arrowverse, Gotham,Titans and Supergirl universe could all have their version of Batman.
I do think that if we were to see Batman anywhere it should be Gotham or Titans. He’s just more important to those shows. On the Arrowverse he’s just a cool Easter Egg, but not really necessary.
