Batman is indeed making his way to GungHo’s Puzzle & Dragons in Japan. Alongside him are trusty pal Robin and arch-nemesis the Joker. Catwoman’s a part of the collaboration, too.
The source of the information is a fan that went digging through the recent 6.1 update for the game, and unearthed images of the characters.
You’ll also be able to get a collectible gashapon machine in the shape of a dragon dressed up in a Batman outfit. Totally legit guys. It ties in with the release of Batman: Arkham Origins.
Oh, alongside the Batman collaboration, there’s also a Baskin Robins (Called 31 in Japan) collaboration going on too to capture the Baskin Robin’s mascot. (Wait, there’s an actual manga version of Baskin Robins’ MASCOT?)
