* AlternateCharacterInterpretation: In TheMovie. [[spoiler: Was Scrappy really corrupted by the artifact like Velma said, or was it all him?]]
* ArchivePanic: This franchise has run since 1969, with ''sixteen series'', four movies, and ten video games.
* AwesomeMusic: In a Halloween Special they got the band {{Music/KISS}}!!!!!!! playing "Shout it Out Loud".
** To be honest, most chase scenes have one of these playing in the background. Several great singers have contributed to the series during the last years.
** The Scooby-Doo series has been nominated for an Emmy twice. The first in 1989 for APupNamedScoobyDoo (daytime Emmy for Outstanding Children's Animated Program) and in 2005 for WhatsNewScoobyDoo (primetime, Outstanding Voice Talent--Mindy Cohn as Velma).
** Even the live-action movies got some great music, particularly the first. {{Outkast}} and BustaRhymes are just the tip of the iceberg.
* CompleteMonster: Jacques from WesternAnimation/ScoobyDooOnZombieIsland and [[spoiler: Nibiru Entity]] from WesternAnimation/ScoobyDooMysteryIncorporated. See their pages for more details.
* DesignatedHero: Think whatever you want about Scrappy but you can't deny the heroes are responsible for his actions in the movie.
* DorkAge: Varies, but around the time Scrappy shows up the show switched from the standard 5 characters. First Velma and Fred disappeared, then Daphne left just Scooby, Shaggy, and Scrappy to bumble around for about a decade. Even for Scooby-Doo, it lost a lot of the original charm until the made-for-video reboots.
* EnsembleDarkhorse: The Scooby Doo Movies in the '90s and beyond definitely suffered from {{Sequelitis}}, but the Hex Girls have remained popular with the fans. They even became a CanonImmigrant in ScoobyDooMysteryInc.
** [[CuteMonsterGirl The Ghoul School Girls]], who only appeared in one special to date, but are fondly remembered by the fanbase.
** Shaggy when compared to the rest of the gang (with the obvious exception of Scooby). Viewers preferred the comedic hijinx he got mixed up in with Scoob, as opposed to the basic mystery solving. He's the only other one to appear in every part of the franchise.
** Out of the main cast, Velma is extremely popular, sometimes even more than Shaggy or Scooby in some parts. Being an {{Adorkable}} [[PerverseSexualLust shapely nerd girl]] probably has something to do with it.
** Also, let's not forget Vincent Van Ghoul from ''The 13 Ghosts of Scooby Doo.'' Being voiced by Vincent Price may have something to do with it, and it's most likely the reason why he returns in ScoobyDooMysteryInc.
** Several of the monsters have become very popular, such as the Tar Monster and Captain Cutler.
* FandomBerserkButton: Referring to Scooby-Doo as TheHero.
* FanPreferredCouple: Daphne/Shaggy. Noticeably in the final seasons where they traveled together with Scooby and Scrappy solving mysteries or battling ghosts, visibly aging and changing clothes, appearance, and van in the final season with no explanation. Surprisingly, (and likely in part to no one willing to admit a Scrappy season had something worth mentioning in it), nobody brings up that the two were together. Seth Mcfarlane also has an unhealthy fixation on Daphne/Scooby, as heard on the FamilyGuy album.
** A 1991 article in Wild Cartoon Kingdom theorizes that not only is Velma a lesbian but she's living her alternative lifestyle with Daphne.
** Alternatively is Shaggy/Velma. The reason Fred got no love(in') is that he was... well... Fred Jones. The only person in the world with less personality than him is Keanu Reaves. Daphne was kind of flat too, in the original, and besides Shaggy and Scooby, Velma was the only one with a semblance of a personality.
* HarsherInHindsight: The disembodied pair of eyes at the beginning of most ''Scooby Doo'' opening credits was pretty sinister to begin with, but at least you knew [[ScoobyDooHoax it was really just some petty criminal who probably wouldn't do any real harm]]. Then we get ScoobyDooMysteryIncorporated, [[spoiler:where we get to meet [[EldritchAbomination Nibiru]], [[CompleteMonster the]] [[KnightOfCerebus most]] [[HeroKiller terrifying]] Scooby villain ever. And he is very, ''very'', '''real'''. What is the first form he takes on? A pair of disembodied eyes, of course!]]
** [[spoiler:The FridgeHorror really sets in when you realize that, due to the creature's nature, the eyes probably mean that ''Nibiru's been watching the gang the whole time.'' And because of his connection to ''Mystery Incorporated's'' CosmicResetButton, which is hinted to be the cause of every ContinuityReboot in the franchise's history, that series probably wasn't the first time the gang fought encountered Nibiru.]]
* HilariousInHindsight: At the end of ''Scooby Doo Pirates Ahoy'' Fred's dad mentions they should give them a trip to the Himalayas for Fred's birthday next year, which Shaggy quickly passes on because he doesn't want to risk a run in with the abominable snowman. The next year's movie, ''Chill Out Scooby Doo'' saw this happen as the main plot.
** ''The New Scooby-Doo Mysteries'' HalloweenEpisode "A Halloween Hassle at Dracula's Castle" saw Shaggy attend a costume party as a werewolf. ''Scooby-Doo and the Reluctant Werewolf'' aired four years later.
** The episode where they're trying to stop the MonsterClown. Said clown hypnotizes Shaggy into being a lion tamer. Shaggy is found in there yelling [[Disney/TheLionKing "Back up there, Simba!"]]
*** The connection is referenced near the end of [[http://www.youtube.com/watch?v=Y1HStmvtkwE this]] YouTubePoop.
** In ''The Scooby Doo Show'' episode "The Tar Monster", there's a character named [[http://scoobydoo.wikia.com/wiki/Ben_Gazi Ben Gazi]], which has become funnier in light of the Republican party's rage over the attack at a US consulate in Benghazi in 2012.
* HoYay: The last scene of the ''What's New'' episode "Pompeii And Circumstance." Supping on a plate of spaghetti, Shaggy and Scooby are sucking in the same noodle, and...well, you know what happens next.
*** Wouldn't that be InterspeciesRomance?
*** Not necessarily, since Shaggy and Scooby were repulsed by the result.
* HoYayShipping: ''Mystery Incorporated'' had a recent recurring sub-plot that had Scooby being jealous of Velma as Shaggy's girlfriend. This is retconned in ''Curse of the Lake Monster'': Shaggy develops a crush on Velma and it has Scooby feeling a bit left out at times.
-->'''Scooby:''' Hmph. Velma, Velma, Velma.
** Subverted at the end--Velma kisses Shaggy smack on the lips and Scooby takes pictures.
** From ''Jeepers, It's The Creeper'': At the school's barn dance, Shaggy is dancing with Velma when Scooby enters and asks Shaggy if he can cut in. To Velma's shock and disappointment, Scooby goes off dancing with Shaggy.
-->'''Velma:''' Well, I've been a wallflower before, but this is ridiculous!
* HollywoodHomely: Subverted with Velma. She fits the appearance but Fred says she's attractive and she even gets a guy for herself.
* LoveItOrHateIt: The live-action movies.
** The franchise in general. Some love the humor and mystery, others hate the formulaic nature, and often poor animation quality.
* MemeticMutation: [[Memes/ScoobyDoo Has its own page]].
* MemeticSexGod: Three, actually.
** Shaggy, despite Fred being the Jock, has been [[{{Shipping}} paired]] with more women than pretty much anyone else in the Hanna-Barbera line, including: Daphne (in WesternAnimation/TheThirteenGhostsOfScoobyDoo), several forgettable one-off characters in the Direct-to-Video movies in the 80s, one in TheMovie, and most recently (and probably dating back to the original where their were light hints) Velma. That's a short, short list.
** The other is Velma. Especially the newest version. Really, you look at Velma, and the first thing that comes to mind is a young and attractive librarian. Lampshaded by later series, where the first movie gives her a makeover, and the [[ScoobyDooMysteryIncorporated latest series]] injected a bit of sultriness into her personality.
** And before that was Daphne, who was most likely intended to invoke this, before viewers' curiousities wandered over to Velma.
* MisBlamed: Many people blame [[TheScrappy Scrappy]] for ruining ''Franchise/ScoobyDoo'' (specifically, dumping half the original cast, switching to a TwoShorts format, and the franchise's first clumsy attempts to lose the ScoobyDooHoax) due to the timing of his introduction. Ironically, Scrappy is what probably saved the show from cancellation way back in 1979. And the success of that new incarnation of Scooby Doo is likely what has kept the franchise going on for some 40 years.
* MoralEventHorizon: There have been some villains that were people dressed as monsters that have actually attempted to murder or critically maim the gang in order to keep their schemes safe (The Snow Ghost, Mr. Hyde, the Ghost of the Red Baron,among others). This explains why Shaggy and Scooby are {{Lovable Coward}}s
* PeripheryDemographic: For most people, the franchise is mere formulaic kid stuff, but science pundit, CarlSagan, loved the show in the sense that it basically promoted a skeptic point of view of the supernatural with the heroes continually exposing paranormal incidents as [[ScoobyDooHoax mere elaborate hoaxes]] and providing logical explanations instead.
* RescuedFromTheScrappyHeap: Ironically, it's not Scrappy but ''Daphne'' who is rescued in [[TheMovie adaptations]], with her move away from being the [[DamselInDistress capture prone]] DamselScrappy.
** This has translated to some of the new animated movies as well, particularly ''Scooby-Doo and the Samurai Sword''.
*** Daphne's old problem of being capture prone is lampshaded in ''Scooby-Doo and the Loch Ness Monster'', with multiple references to the Blake family being danger prone.
**** Which is a MythologyGag in and of itself, as during the original series, Daphne's nickname (both in-series and [[FanNickname by fans]]) was "Danger-Prone Daphne".
** Funny enough, Scrappy himself ''was'' rescued for several shows. He matured somewhat and showed capability to actually handle some of the bad guys, unfortunately this largely goes unnoticed, even by people who ''work'' on the show.
* TheScrappy:
** Scrappy is so infamous that he is the TropeNamer. Also an example of LeeroyJenkins, annoying the audience with his thoroughly obnoxious behavior of vainly boasting about picking a fight with villains he couldn't hope to harm. Our page for TheScrappy tells much more about why the show introduced Scrappy, why the fans came to hate him, and how the franchise reacted.
** Before Scrappy, there was Scooby-Dum. Though generally speaking, people didn't seem to mind him as much, as he had a low key personality in contrast to Scrappy, who started out as high-strung and obnoxious. Barring a few cameos and reunions, he also turned up rarely in the franchise after his initial series.
** ''WesternAnimation/The13GhostsOfScoobyDoo'' had an EthnicScrappy in the form of Flim-Flam. What makes this example amazing is that Scrappy himself was in the show, but due to a setup that made better use of his usual antics, he became RescuedFromTheScrappyHeap. The result is that Flim-Flam became more of a Scrappy than the actual Scrappy.
* UglyCute:
** [[CuteMonsterGirl The girls]] in ''Scooby-Doo and the Ghoul School'', especially PattyMaloney as the mummy girl.
** "Fred Bat" in the WNSD episode "The Vampire Strikes Back"
