Coming this fall, Batman: The Brave and the Bold is based on the animated television series and will include co-op play and the ability to link the DS and Wii versions of the title.
Playable characters in the game include Batman, Robin, Green Lantern, Blue Beetle and Aquaman and Warner Bros. says there will be "dozens of popular villains" to fight.
If you link the DS and Wii versions of the game together it unlocks Bat-Mite as a playable character who can then be controlled with the DS alongside the main characters in all levels of the Wii version of the game.
The game is being developed by Wayforward, the folks behind Contra 4, Looney Tunes Duck Amuck for the DS and the 2009 version of A Boy and His Blob for the Wii.
None of this explains why the game has a title that is a better fit for a soap opera than a crime-fighting brawler.
