The CW recently set the dates for the annual Arrowverse crossover, with this year’s storyline heading to Gotham City, a place previously off-limits to The CW.
The crossover will start with The Flash on Sunday, December 9.
The crossover event stars Stephen Amell as Oliver Queen/Green Arrow, Melissa Benoist as Kara Danvers/Supergirl, Grant Gustin as Barry Allen/The Flash along with guest stars Ruby Rose as Kate Kane/Batwoman, Tyler Hoechlin as Clark Kent/Superman and Elizabeth Tulloch as Lois Lane.
That said, Batman does exist in this world, and Oliver Queen called him out by name last season on Arrow.
