- As the issue is based on the Teen Titans Go! TV series aired on Cartoon Network, Daphne breaks the fourth wall a little, by commenting on how Robin looks different and doesn't sound like Shaggy anymore (Casey Kasem was the voice of both Shaggy and Robin in The New Scooby-Doo Movies), with Starfire responding that she thinks he sounds like Green Arrow's sidekick, Speedy (Scott Menville voices both Robin and Speedy in the former.)
- None known.
Inconsistencies/continuity errors and/or goofs/oddities
- This is a crossover on a purely superficial level, as the art and characterizations are just being mimicked (presumably done as a "tie-in" to get more readers). Robin's difference in personality is justified by explaining that he acts more mature around Batman, where as with the Titans, he's with people of his own age that give him little respect and no self control.
- The referencing of how different Robin sounds from Shaggy is kind of lost, as Scott Menville did voice Shaggy in Shaggy & Scooby-Doo Get a Clue!.
- Trigon being ruler of the netherworld conflicts with the Goblin King ruling of the spirit world in the direct-to-video, Scooby-Doo! and the Goblin King. How different can they really be?
