From what I know,
Scooby-Doo has been rebooted several times, with this being the summary of the "Main" continuities:
>Classic Scooby
This is basically
all of the
Scooby-Doo material from when the series first started in '69 that runs all the way up to
13 Ghosts in '85. This continuity also includes the TV movies (
Boo Brothers,
Ghoul School, and
The Reluctant Werewolf) and the first four D2V films (
Zombie Island,
Witch's Ghost,
Alien Invaders,
Cyber Chase), with
Cyber Chase effectively being the "finale" of that version of the gang. The only recent material that still "exists" here is the 2019 D2V
Curse of the 13th Ghost (Taking place after the shows, but before the
other movies) and the 2019 series
Scooby Doo And Guess Who.
>A Pup Named Scooby
This continuity started with
A Pup Named Scooby-Doo in '88, carried over into
What's New, Scooby-Doo? in 2002, and also reflected the D2V films from
Legend of the Vampire (2003) to
Samurai Sword (2009). References to the original series are minimal and this universe is mostly it's own thing.
>Mystery Inc.
This it the third "main" continuity of the
Scooby series that's centered entirely around the
Mystery Incorporated series, and the D2V films from
Abracadabra-Doo (2010) up to the present. This universe references a lot of the characters and events of the other series, but they are
not the same gang. In fact,
Mystery Inc. ends on the note of the Scooby gang travelling across parallel worlds.
>Live-Action
This continuity exists on a similar note to
Mystery Inc., where similar events of all the previous series did happen (As of 2004) but it's not the "same gang". Outside of the two theatrical films (
Scooby Doo,
2: Monsters Unleashed, and the two TV movies (
The Mystery Begins,
Curse of the Lake Monster), the only other "canon" material here is the 2009 video game
First Frights and it's 2010 sequel
Spooky Swamp.
>Other
This is where practically
all of the material not listed exists as they don't really mesh well elsewhere. This includes the one-off series (
Get A Clue,
Be Cool, and
Velma), the other films (
Goes Hollywood,
Daphne & Velma,
Scoob), the comics (
Apocalypse), the games, etc. All this material can effectively be written off as "non-canon" or side stories that can be "canon" to one of the afformentioned continuities so long as it doesn't contradict them.
