There is a scene in the closing credits: the Teen Titans from Teen Titans (2003) send a transmission, stating they may have found a "way back".
There is a scene at the end of the closing credits: the Challengers of the Unknown, who were sucked into a portal by Raven earlier in the movie, are still trapped there, complaining that they missed the movie.
At the end of the closing credits (after the scene with the Challengers), the tag "To Be Continued on Cartoon Network" appears. The tag refers to the then-upcoming Tower Renovation (2018) airing on Cartoon Network, which resumed the show following up from the events of the film.
In the home media release, the tag is completely absent.
The film opens with a montage of flipping comic-book pages from the "The New Teen Titans" comic (#1, November 1980), in a parody of the Marvel Studios logo.
Robin interrupts the end credits, attempting to give the moral to the movie.
Daffy Duck runs wild around the Warner Bros Animation logo, then an annoyed Porky Pig pulls him away.
As with all Warner Bros. animated movies since The Iron Giant (1999), there are no opening credits, asides from the studio logos and the title of the film.
Closing credits presented as neon signs, with dancing characters accompanying their respective actors
In the ending of the end credits roll in the theatrical release, the dedication of the words said, "for Craig Mack & Lil Peep and Fredo Santana, his Rapper and Performer." can be seen (Unfortunately, Craig Mack & Lil Peep and Fredo Santana are all rap artists who died shortly before the release of this movie: Peep on 2017-11-15, Fredo on 2018-01-20, and Mack on 2018-03-12.) In home media release, the dedication is completely absent.
