To mark the 75th anniversary of Batman, DC Entertainment premiered a new “Batman Beyond” short at WonderCon 2014 Saturday (April 19) that is slated to air Wednesday, April 23 following “Teen Titans” on Cartoon Network — but you can watch it here first.

In the clip, an elderly Bruce Wayne (Kevin Conroy) tells protege Terry McGinnis (Will Friedle) that Batman has finally met his greatest foe: Himself. The two fight various Batman robots as the clip showcases decades worth of different Batman incarnations, you can read a break down of the different iterations at Yahoo Movies.
