The CW president Mark Pedowitz confirmed today that Batman will not be appearing on the network’s superhero shows, specifically the in-development Batwoman series. “There’s no discussion about a series,” Pedowitz said (via EW).
In 2008, The CW had to scrap plans for a Dick Grayson series called The Graysons because of the studio.
Batman already exists in the Arrowverse because last season Oliver Queen mentioned his name at one point.
If the Batwoman pilot is picked up, the series could air in 2019.
