The CW previously 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 CW has released a brand new teaser promo for their upcoming Arrow-verse crossover event titled Elseworlds, featuring our introduction to Ruby Rose’s Kate Kane/Batwoman as she meets with Barry Allen and Cisco.
The video also gives us a glimpse of Gotham City’s infamous Arkham Asylum.
That said, Batman does exist in this world, and Oliver Queen called him out by name last season on Arrow.
