These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Archive Panic: This franchise has run since 1969, with sixteen series, four movies, and ten video games.
Awesome Music: In a Halloween Special they got the band 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 A Pup Named Scooby-Doo (daytime Emmy for Outstanding Children's Animated Program) and in 2005 for What's New, Scooby-Doo? (primetime, Outstanding Voice Talent—Mindy Cohn as Velma).
Even the live-action movies got some great music, particularly the first. Outkast and Busta Rhymes are just the tip of the iceberg.
Designated Hero: Think whatever you want about Scrappy but you can't deny the heroes are responsible for his actions in the movie.
Dork Age: 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.
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 Adorkableshapely 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 Scooby-Doo! Mystery Incorporated.
Several of the monsters have become very popular, such as the Tar Monster and Captain Cutler.
Fan-Preferred Couple: 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 Family Guy 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.
The Fridge Horror 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'sCosmic Reset Button, which is hinted to be the cause of every Continuity Reboot in the franchise's history, that series probably wasn't the first time the gang fought encountered Nibiru.
As of 2012, the episode "The Tar Monster" may fall into this, as the name of the government official was "Ben Ghazi"
Hilarious in Hindsight: 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 MysteriesHalloween Episode "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.
Ho Yay: 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. Might be considered Interspecies Romance if Shaggy and Scooby weren't repulsed by the result.
Ho Yay Shipping: 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!
Hollywood Homely: Subverted with Velma. She fits the appearance but Fred says she's attractive and she even gets a guy for herself.
Shaggy, despite Fred being the Jock, has been paired with more women than pretty much anyone else in the Hanna-Barbera line, including: Daphne (in The 13 Ghosts of Scooby-Doo), several forgettable one-off characters in the Direct-to-Video movies in the 80s, one in The Movie, 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 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.
Mis-blamed: Many people blame Scrappy for ruining Scooby-Doo (specifically, dumping half the original cast, switching to a Two Shorts format, and the franchise's first clumsy attempts to lose the Scooby-Doo Hoax) 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. It doesn't help that nearly everyone hates the poor character as if he had destroyed an entire planet despite the fact he was only created by mandate. To put how much people don't like him is...an understatement.
Moral Event Horizon: 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 Cowards
Periphery Demographic: For most people, the franchise is mere formulaic kid stuff, but science pundit, Carl Sagan, 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 mere elaborate hoaxes and providing logical explanations instead.
Scrappy is so infamous that he is the Trope Namer. Also an example of Leeroy Jenkins, annoying some of 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 The Scrappy 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. Scooby Dum even made it into the Laff-a-lympics team over the other gang members.
"Fred Bat" in the WNSD episode "The Vampire Strikes Back"
The Woobie: Some will feel that Scrappy is this. The poor character hasn't appeared in the longest time, is blamed by not just half of the fanbase but by the people currently owning Scooby Doo. Even Cartoon Network takes jab at him at times. Even though he hasn't been seen since, many, many fans feel he might as well be THE Woobie of the franchise.
