To help celebrate Batman's 75th Anniversary this year, Warner Bros. commissioned Darwyn Cooke to create a new Batman short set within the world of the animated series Batman Beyond, which the studio debuted at WonderCon yesterday. The full short can now be watched online, featuring the return of Batman Beyond voice actors Kevin Conroy and Will Friedle as Batman/Bruce Wayne and Terry McGinnis. The short will also air Wednesday, April 23 after an episode of Teen Titans. It isn't known if this short is being used to gauge fan response to see if Batman Beyond can come back, after its original run lasted between 1999 and 2001.

In related news, Toonami's Jason DeMarco announced that Beware the Batman, which joins the Adult Swim/Toonami lineup on May 10, will air all of the previously unaired episodes on the network.
