The CW's annual Arrow-verse crossover is introducing a DC Comics favorite.

Arrow star Stephen Amell announced Thursday at the network's upfront presentation that Batwoman will appear during the network's annual crossover event.

CW president Mark Pedowitz confirmed that introducing Batwoman marks the first time the character will appear "on any screen." The character will be "fighting alongside" The CW's heroes, Amell said, with the crossover airing in December. Additional details, including a character description for The CW character or actress, were not immediately available.
