The original animated Teen Titans and their comedic Teen Titans Go! counterparts face off for the first time in the first trailer for an upcoming crossover movie. An end credits scene following Teen Titans Go! to the Movies teased the return of the original animated characters — which many hoped would be a sixth, conclusive season to the show — but in October, a brief teaser trailer included with the Teen Titans Go! to the Movies DVD announced a project entitled Teen Titans Go! vs. Teen Titans.

The first trailer for the movie shows the bouncy Teen Titans Go! characters facing new opponents in a mysterious arena. The twist? It’s the more “serious” versions of themselves that they must battle.

The original Teen Titans animated show ran from 2003 to 2006, culminating with a TV movie send-off. The show had a sort of spiritual Cartoon Network successor in Young Justice, another animated show focused on a group of fresh-faced heroes that mixed lighthearted teen shenanigans with more serious storylines. In 2013, the goofy Teen Titans Go! took over the canceled Young Justice’s programming block on Cartoon Network’s DC Nation.

As with any reboot of a beloved childhood show, Teen Titans Go! garnered some criticism from fans of the original, but high ratings and viewership from its target audience still keep it in rotation on Cartoon Network. Teen Titans Go! regularly spoofs this criticism, with one episode featuring the team meeting the more serious Young Justice characters. This movie appears to continue that gag.

This will be the first appearance by the original Teen Titans since Teen Titans: Trouble in Tokyo in 2006. All five seasons of the original show can be found on DC Universe. Teen Titans Go! Vs. Teen Titans comes out later this year on DVD and Blu-ray.
