In what has to be one of the Dark Knight's most bizarre crossovers, DC Comics has announced a Batman: Arkham Origins level for Puzzle & Dragons, the popular free-to-play mobile game. Puzzle & Dragons really doesn't have anything to do with Batman or even comics; think of it as Bejeweled-Pokemon hybrid.

It's actually one of the most popular games in Japan, and it's beginning to gain traction in the United States, but it's somewhat of a mystery as to how Arkham Origins is a good fit for the formula. If anything, it seems like the artistic style of the Arkham universe wouldn't really mesh with the style of Puzzle & Dragons. Players can apparently add The Joker to their monster boxes with Batman, Robin and Catwoman available through a special in-game Egg Machine.

There's certainly an argument to be made that it gives Batman fans a chance to jump in to Puzzle & Dragons for the added benefit of playing just DC characters, but the entire dungeon goes away Nov. 12. Honestly, I'm not quite sure what the benefit is to this promotion for DC. It doesn't really give Arkham Origins that much more exposure, and at best, it draws people into a mobile game that's not even run by DC or Warner Bros. Maybe someone at DC just really likes Puzzle & Dragons. It could even be a response to the debut of Marvel Puzzle Quest on iOS -- a Bejeweled style game with RPG elements that follows the basic story of "Dark Reign."

No matter what the reason for it is, the Arkham Origins-themed dungeon is available now for Puzzle & Dragons.
