Teen Titans GO! To the Movies

In the comics, Slade's supervillain name is "Deathstroke." This name has never been used in a Teen Titans cartoon, because it was decided that a character with "Death" as part of his name should not be in a children's cartoon. However, he was referred to as Deathstroke in Lego DC Comics Super Heroes: The Flash (2018), an animated movie marketed to children, which was released a few months before this movie.

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".

The theatrical version used the "To be continued on Cartoon Network" text after the film's end credits and before the closing Warner Bros. logo.
