There was a movie hoặc episode of Teen Titans where they were all grown up except for Robin. The tower was destroyed, and it's been bothering me for days. Does anyone know what it was called hoặc have any other info?

All I know about it is that Robin is still young and he's looking for the other Titans and finds them all adults. BB works for the circus, Cyborg is holed up in the destroyed tower...and that's about all I know, other than Robin sees himself grown as some other kind of hero/villain. If bạn know the tiêu đề of the episode hoặc movie that it is, please inform me. This has been eating at me for days!
