Someone on Reddit posted the picture of an ad from the inside of Mad magazine. The ad is for the popular worldwide game from GungHo Studio, Puzzle & Dragons, showing off that there is a DC Comics Collab coming to the game in November.
The ad says that both heroes and villains are coming, "Superman, Wonder Woman, Green Arrow, Doomsday and more!"
My guess is that Batman probably won't be included, as he's already been part of a collab. But Flash, Aquaman, Cybord and Green Lantern are not listed, and I'm hoping they're part of it.
