The TV series 'Scooby-Doo And Guess Who?' should be revived for a 3rd season that's 26 episodes long and that uses the stories from the comic book series 'Scooby-Doo Team-Up', but with things that contradict previous mainline entries of the 'Scooby-Doo' franchise & other previous Hanna-Barbera media being removed. In the adaptation of the story in which Mystery Inc meets the Teen Titans of the TV series 'Teen Titans Go!', Mystery Inc should somehow end up in the universe of said TV series, with it being established that Mystery Inc has meet said universe's versions of the Teen Titans before.

There should be a film that involves Scooby-Doo having a family reunion, where it is revealed that after the events of 'Scooby-Doo And The Reluctant Werewolf', Scrappy-Doo became a celebrity, hence the plush toys of him briefly seen in 'Scooby-Doo And The Goblin King', and is now an adult but has the same appearance & size he did as a puppy due to a rare condition. It should also be revealed that after the events of 'Scooby-Doo And The Reluctant Werewolf', something happened to the Mystery Inc gang that has caused them to occasionally have memory lapses ever since, such as when they forgot that they had previously encountered real supernatural threats before the events of 'Scooby-Doo On Zombie Island', Shaggy at one point not believing in the existence of Australia(despite the fact that he had been there before), etc.

'Scooby-Doo' video games(including home console video games, portable console video games, PC video games, and online video games), story books, and comic books(including those published by DC Comics, Marvel Comics, Gold Key Comics, and Archie Comics) that have original stories and were done in the style of the main Scooby-Doo universe should be adapted via a new Scooby-Doo TV series that's set in the main Scooby-Doo universe, with the stories being presented in unabridged fashions. The adaptations of the video games should have the music from the video games. This TV series should have various intros, with each intro having one of the various versions of the song 'Scooby-Doo, Where Are You!', the theme song of 'The New Scooby-Doo Movies', or the Simple Plan version or Anarbor version of the song 'What's New, Scooby-Doo?' being played in the background. The tone should depend on the story being told, with tones ranging from the tone of 'Scooby-Doo, Where Are You!' and 'The New Scooby-Doo Movies'(stories that have that tone should have laugh tracks) and the tone of 'Scooby-Doo On Zombie Island'. Songs used in previous 'Scooby-Doo' chase scenes should be used in this TV series.
