Cartoon Network has announced that the final seven episodes of Beware the Batman will air in a marathon during Adult Swim’s Toonami programming block on Saturday, September 28, beginning at 2:30 a.m. ET. (via World’s Finest).

The show is finally being written off by Cartoon Network. The decision seems to be a last minute one, as Adult Swim had announced that the series would be moving to a new timeslot less than a week ago. The marathon is described as “one last Bat-blowout” before the network relinquishes broadcasting rights to the series.

Beware the Batman was originally a part of Cartoon Network’s DC Nation programming block. Like the other shows DC Nation animated shows, which included Young Justice and Green Lantern: The Animated Series, Beware the Batman has a strong fan following, but was subject to last minute schedule changes by the network for various rumored and unconfirmed reasons, ranging from the related toys and merchandise not selling well enough, to network executives feeling that supehero shows were no longer kid-friendly enough for the network’s tone.

The kid-friendly comedy Teen Titans GO! and the various comedic DC Nation shorts are all that remain of the one-time fan favorite animation block.
