Notes:

In a new take on the series, the entire original gang is reunited, but this time as much younger versions of themselves. The series was fairly successful and as such ran for 4 seasons.

Notes:

DynoMutt is a robotic Doberman Pincer, who with the help of his human, superhero companion, the Blue Falcon, repeatedly save Big City from the super-villain of the day. This show double-billed with Scooby-Doo, as The Scooby-Doo/DynoMutt Hour.

Notes:

The first season of this series featured Scooby and his nephew, Scrappy in 30 minute episodes. However, the second season onward were 10 minute episodes as single segments in other shows, including:

The Richie Rich/Scooby-Doo Show
The Scooby & Scrappy-Doo/Puppy Hour.

It was with the introduction of Scrappy-Doo that Scooby and his friends started capturing actual ghosts, rather than just humans in elaborate costumes and masks.

Notes:

Returning once again to the original formula, this series implies that it takes place during same time as the original series. The masked villain of the week is far more complex than in the original series and there is a very tongue-in-cheek approach taken to many of the original stories and gags. However, this series definitely embraces the concept of story arcs much more than any of the previous incarnations, as well as character development. The Scooby-Doo series has definitely grown up and is ready for the more sophisticated youth of today.

Notes:

This is the original series that started one of the longest running, most successful cartoon series of all time.

This short film parodies the original Scooby-Doo series in-gags and has plenty of random guest stars. It was created to air as cut scenes between episodes of Scooby-Doo during a Cartoon Network's Scooby-Doo marathon and was eventually shown in its entirety.
