The next Arrowverse crossover airs in December.
The next Arrowverse crossover will feature Batwoman.
This will mark the first time the character will make an appearance on any screen in any movie or TV show, and she will be helping out The CW’s superheroes. It’s not currently known who will portray Batwoman. The character made her debut in 1956’s Detective Comics #233.
As a result, the city of Gotham will also be incorporated. But this does not mean Fox’s Batman prequel Gotham will be crossing over with the The CW DC shows, as Gotham hails from different producers.
The Arrowverse crossover will include the following shows: Arrow, The Flash, Supergirl and Legends of Tomorrow.
