!Mystery Inc.

!!Scoobert "Scooby" Doo
->Voiced by:\\
Creator/DonMessick (1969-1994)\\
Hadley Kay (1997)\\
Scott Innes (1999-2001, 2001-2006 video games)\\
Neil Fanning (2002-2004 Live Action Films)\\
Creator/FrankWelker (2002-2013)\\

* ActionPet: When he needs to be.
* BigEater: With Shaggy. When Shaggy is about to bite his DagwoodSandwich, expect Scooby to swallow it.
* BigFriendlyDog: Scooby is not aggressive. He does not attack monsters. He runs away from them.
** And a good thing too. It's easy to forget since he's so goofy, but Scoob's almost as big and heavy as a grown man.
* TheBigGuy: Dumb as a dog, but loyal -- though he may require a Scooby snack -- and necessary to sniff out clues.
* ButtMonkey: Often drifts into this.
* CatchPhrase: "Scooby Dooby Doo!" and "[[SpeechImpairedAnimal Ruh-oh!]]"
* ClassicalAntiHero: Barely. With his massive cowardice, Scooby's just as likely to avoid taking part in a mystery, as he is to take the role of the hero.
* CoolUncle: Scrappy thinks of Scooby this way, despite Scooby's cowardice.
* CowardlyLion: Scooby's cowardice was likely [[{{Flanderization}} Flanderized]] through time, but whenever you get in his way, he can definitely take you down.
* CrouchingMoronHiddenBadass: In some iterations.
** ''WesternAnimation/ScoobyDooMysteryIncorporated'' had his most Badass form when he "killed" a robot double who tried to kill his frends with a forklift! His line to the robot? "PLAY DEAD!"
** ''WesternAnimation/BatmanTheBraveAndTheBold'' had the Scooby Gang run into Batman and Robin. It just happens that [[RealityWarper Batmite]] also [[TookALevelInBadass helps]] Scooby and Shaggy into the fight as well.
* DetectiveAnimal: Whenever the gang is investigating another mystery.
* DogsAreDumb: Played with, for while he's certainly [[WesternAnimation/YogiBear smarter than the average dog]], Scooby is usually the least intelligent member of the team.
** There are times he gets lucky in what he does just happens to be heroic enough to save the day (once when Jeannie was trapped in a bottle and surrounded by a force field that only sound could penetrate, Scooby howled at a pitch high enough to shatter the bottle's glass).
** In the movies, he very obviously TookALevelInDumbAss.
* TheDragAlong: Like Shaggy, Scooby has to be coerced with promises of Scooby Snacks.
* EmbarrassingFirstName: The name ''Scoobert'' wouldn't be officially established until ''WesternAnimation/APupNamedScoobyDoo''.
* {{Flanderization}}: See CowardlyLion.
* HeroicDog: And the VillainOfTheWeek would have gotten away with it, if YouMeddlingKids didn't have a dog.
* HeroismIncentive: WouldYouDoItForAScoobySnack
* HeterosexualLifePartners: With Shaggy, in a rare man and dog example.
* IdiotBall: Scooby carries this throughout some movies and incarnations.
* InvincibleIncompetent: With Shaggy. They always seem to end up finding the weekly monster despite their cowardice, laziness, and their -[[DependingOnTheWriter usually]]- complete lack of investigative skills.
* LargeHam: Often in the original series when he needs to be the bait and tries to get out of it.
* LetsGetDangerous: When anyone he really cares about is in trouble. There was even one moment when Velma was captured and Scooby turned down a Scooby Snack, saying he didn't need it to be persuaded to help rescue her.
* LovableCoward: Though he ''does'' have his hero moments. See CowardlyLion above.
* OnlyKnownByTheirNickname: See EmbarrassingFirstName above.
* RogerRabbitEffect: Even though the humans are also cartoons, Scooby-Doo far exceeds them in his ability to do ToonPhysics. Shaggy shares this ability to a lesser degree.
* SpeechImpairedAnimal: All of Scooby's words invariably start with an 'R', except for when he says his name, and sometimes even then.
* TalkingAnimal: A talking Great Dane.
* TeamPet: although it could be argued that ''he'' is the hero, and the MeddlingKids are his ''sidekicks''.
* TookALevelInBadass: In some incarnations, mostly the movies.
* TookALevelInDumbAss: In the live-action movies. See DogsAreDumb above.
* TookALevelInJerkass: In ''WesternAnimation/ScoobyDooMysteryIncorporated'', which adds to the attempt in developing the characters. He got better, of course.

!!Norville "Shaggy" Rogers
->Voiced by:\\
CaseyKasem (1969-1994, 1997, 2002-2009)\\
Creator/BillyWest (1998)\\
Scott Innes (1999-2001, 2001-2009 video games)\\
Creator/ScottMenville (2005-2008)\\
Matthew Lillard (2002-2004 Live-Action Movies, 2010-2013)\\
Nick Palatas (Creator/CartoonNetwork Films)
* AdaptationalAttractiveness: Not as much as Velma, but "What's New Scooby Doo" and the live actions films do feature a Shaggy more attactive than the skinny, lanky original Shaggy.
* {{Adorkable}}
* BigEater: With Scooby. If Fred wants to find a monster, Shaggy will volunteer to investigate the kitchen, and prepare a large snack for himself and Scooby -- until the monster comes to interrupt the meal.
* CatchPhrase: "Zoinks!"
* CrouchingMoronHiddenBadass: In some iterations.
* DependingOnTheWriter: Whether Shaggy is vegetarian or not. In TheMovie he's portrayed as vegetarian, as he was in ''WhatsNewScoobyDoo'' and the ''Scooby Doo Behind the Scenes'' shorts, but recently he seems to be back to his old ways.
* TheDragAlong
* EmbarrassingFirstName: Norville. Thus, he only goes by "Shaggy".
* {{Flanderization}}: He and Scooby have both grown increasingly cowardly over time, although they do have their {{Badass}} moments.
* GreaseMonkey[=/=]MrFixit: Whenever Shaggy is shown to actually have a job, it's invariably related to cars or mechanics.
* HeterosexualLifePartners: With Scooby.
* InvincibleIncompetent: With Scooby. They always seem to end up finding the weekly monster despite their cowardice, laziness, and their -[[DependingOnTheWriter usually]]- complete lack of investigative skills.
* KavorkaMan: It's not so much that Shaggy is a pimp, but many episodes and movies have shown that many an attractive female seems to think Shaggy is hot.
* KnownOnlyByTheirNickname: You'd never know what his real name was in the show. (It was revealed in a ''APupNamedScoobyDoo''.)
* TheLancer: When the gang does split up, Shaggy leads one half. Shaggy (along with Scooby) often notices creepy things that Fred had missed. Shaggy is likes to sneak away with Scooby to [[BigEater eat a large snack]].
* LetsGetDangerous: He'll do anything to help his dog. This applies also to the girls and Fred, but to a lesser extent.
* LikeIsLikeAComma: Part of his [[ValleyGirl Hippie Speak]]. In one episode of ''ScoobyDooMysteryInc'', like, Velma is trying to, like, make him, like, stop.
* LovableCoward: In the early seasons, it's justified as even though the so-called monster is a person pulling a ScoobyDooHoax, they are still sometimes dangerous criminals who will kill if their trick doesn't scare off the intruder. Later season remove that fact.
* NervousWreck: Usually.
* StonersAreFunny: Shaggy from ''Franchise/ScoobyDoo'' may or may not be an actual stoner, but how can people ''not'' jump to that conclusion? He's always hungry (he eats ''dog treats'', for crying out loud), he's always freaking out over monsters, he thinks his dog (Scooby) can talk, and he even looks and speaks like a hippie stereotype. Talk about GettingCrapPastTheRadar.
* ValleyGirl: Like, a male example of Hippie Speak. Still doing it forty years later, man.
* {{Ventriloquism}}: Shaggy will sometimes use his ability to "throw his voice" to fool the villains.
* WagTheDirector: Shaggy becomes vegetarian whenever Casey Kasem plays him in modern times, because Kasem himself is vegetarian and refused to reprise the role otherwise.

!!Velma Dace Dinkley
->Voiced by:\\
Nicole Jaffe (1969-1973, 2001, 2003-2004)\\
Pat Stevens (1976-1982)\\
Marla Frumkin (1979)\\
Christina Lange (1988-1991)\\
Creator/BJWard (1984, 1997-2001)\\
Mindy Cohn (2002-2013)\\
Linda Cardellini (2002-2004 Live-Action movies)\\
Hayley Kiyoko (Creator/CartoonNetwork movies)
* AdaptationalAttractiveness: Varies, but she gets hit with this semi-often. While not truly ugly, Velma is traditionally overweight looking, with a short-and-stout appearance, tacky haircut and a relatively plain face. Starting with ScoobyDooOnZombieIsland, this started to change somewhat, ''especially'' in WhatsNewScoobyDoo and the movies (much like Shaggy): where she's made very petite with a tiny waist and an hourglass figure, with a cute-as-a-button face to boot. And in the live action films, she's played by very attractive actresses. The most recent animated movies fuse these two somewhat, and ''Mystery Incorporated'' brings back her original appearance, but with a very stylized appearance.
* {{Adorkable}}
* AdventurerArchaeologist: She becomes one in ''Where's My Mummy'' and probably has the greatest CrowningMomentOfAwesome in the Scooby history.
** Interestingly, in an episode of ''The New Scooby-Doo Mysteries'', Velma has an uncle named John who's an archaeologist.
* AgentScully: She is the more vocal skeptic of the group, but for the most part she just goes along with it.
* BlindWithoutEm: "My glasses! I can't see without my glasses!"
* BrainyBrunette
* CatchPhrase: "Jinkies!"
* DeadpanSnarker: Mainly her most recent incarnations.
* GadgeteerGenius: Velma arguably qualifies, at least in ''What's New, Scooby-Doo?'' where she's capable of building (among other things) a robot dog with a remarkable number of functions and an MP3 player the size of a sugar cube (though the latter lacked earphones).
* HollywoodNerd
* JerkWithAHeartOfGold: In ''ScoobyDooMysteryIncorporated''.
* MagicSkirt
* TheMeddlingKidsAreUseless: ''Averted''.
* {{Meganekko}}: Possibly even an UrExample of the trope.
* UsefulNotes/{{NASA}}: In at least one series, she left the gang to work for NASA as a rocket scientist.
* OnlySaneMan
* PerpetualSmiler: Unless something annoys or scares her, she can almost always be seen sporting a content smile no matter what's going on - especially noticeable during the summations, which she almost always does with a big smile on her face. Particularly used in the more recent movies, where most things that make her frown last less than a few seconds.
* PluckyGirl
* PutOnABus: In the '80s era productions, Velma left the group to work for NASA, occasionally visiting for episodes about astronauts or the White House being haunted.
* RaceLift: Vaguely Asian in the live action TV movies.
* [[TheSmartGuy The Smart Girl]]: Dur.
** AddedAlliterativeAppeal: Half her dialog in ''The Mystery Begins''...
** SesquipedalianLoquaciousness: ...And the other half.
* SweaterGirl
* TeenGenius
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Clowns?]]: In ''What's New Scooby-Doo?'' as the result of an incident at a childhood birthday party.
* WomenAreWiser
* YouthfulFreckles
* ZettaiRyouiki: Grade C

!!Daphne Ann Blake
->Voiced by:\\
Indira Stefanianna Christopherson (1969-1970)\\
Heather North (1970-1997, 2003)\\
Kellie Martin (1988-1991)\\
Creator/MaryKayBergman (1998-1999)\\
Music/GreyDeLisle (2000-2013)\\
Creator/SarahMichelleGellar (2002-2004 Live-Action movies)\\
Kate Melton (Creator/CartoonNetwork movies)
* ActionGirl: In the live-action movie.
* AdaptationalBadass: Overall, Daphne has been portrayed as more {{badass}} in later adaptations than in earlier ones, but she still flits between being an ActionGirl and DistressedDamsel in each production.
* BikerBabe: Shown in recent movies, such as ''[[WesternAnimation/ScoobyDooLegendOfThePhantosaur Phantosaur]]'' and ''[[WesternAnimation/BigTopScoobyDoo Big Top]]''.
* BoundAndGagged: Quite frequently.
* CatchPhrase: "Jeepers!"
* TheChick
* CrimefightingWithCash: In the ''Pup Named Scooby-Doo'' prequel, she's revealed to basically be the financier for all the investigations.
* DefrostingIceQueen: As a kid, in flashbacks and prequels.
* DesignatedVictim: Typically being the member of the gang most likely to get abducted, get trapped, get hypnotized, fall through a secret passage...
* DamselInDistress
* FieryRedhead
* GracefulLadiesLikePurple
* HartmanHips
* HotScoop
* ImpossibleHourglassFigure
* InSeriesNickname: Danger-Prone Daphne.
* IntrepidReporter: Whenever she's an adult, this is usually her career.
* TheKlutz: In ''Scooby-Doo, Where Are You!''
* MacGyvering: In ''What's New, Scooby Doo?''
* MagicSkirt
* MsFanservice
* ParentService
* PluckyGirl
* ProperTightsWithASkirt
* PutOnABus: Daphne was the last character other than Scooby-Doo or Shaggy to leave the cast before the series' major revival, apparently to become a journalist.
* {{Redheaded Hero}}ine
* ShesGotLegs
* SpoiledSweet
* StylishProtectionGear: In winter episodes, she wears a fancy coat [[PrettyInMink trimmed with fur]].
* TookALevelInBadass: And has kind of bounced around between ActionGirl and DistressedDamsel in search of a happy medium ever since.

!!Fred "Freddie" Herman Jones
->Voiced by:\\
Creator/FrankWelker (1969-1983, 1997-2013)\\
Carl Stevens (1988-1991)\\
Freddie Prinze Jr. (2002-2004 Live-Action movies)\\
Robbie Amell (Creator/CartoonNetwork movies)
* BadassDriver: One of the main reasons why he is needed on the team(along with leadership skills), because when you see the insane obstacle courses the gang encounter in all of these mysteries, you know that Fred ''has''to be an awesome driver to make sure the mystery is solved. He never disappoints in this field.
* BowtiesAreCool: Fred's stubborn attachment to his apricot ascot has evolved into a variant of this.
* BrainlessBeauty: In the live-action films, and occasionally elsewhere.
* CatchPhrase: "LetsSplitUpGang!"
* {{Cloudcuckoolander}}: Often in recent times, but ''APupNamedScoobyDoo'' is the worst offender.
* CluelessDetective: Fred started out as being perhaps the most intelligent member of the team behind Velma, and essentially become less competent the longer the franchise has run, [[TookALevelInDumbass with a lot of his intelligence and leadership qualities changing hands from him into Daphne]]. This reached its apex in situations where he became the least competent member of the team with Shaggy and Scooby often outwitting him. He's gotten a bit better since then.
* ConspiracyTheorist: As a kid in ''APupNamedScoobyDoo''. See the Red Herring example below.
* CrazyPrepared: In ''What's New, Scooby-Doo?'', Fred has made enough "special modifications" to the Mystery Machine to put Han Solo to shame, including fitting it with a roof airbag which conveniently enables Shaggy to save Velma when she falls off a highrise movie set in "Lights, Camera, Mayhem".
* TheDitz / DumbBlonde: Has been [[{{Flanderization}} Flanderized]] into this starting with APupNamedScoobyDoo but more prevalent with his portrayal by Freddie Prinze, Jr. and then increasingly obvious in the installments ''WhatsNewScoobyDoo'' and ''ScoobyDooMysteryIncorporated''.
* {{Flanderization}}: Into a DumbBlonde with equal parts of a {{Cloudcuckoolander}} and a [[TheDitz Ditz]]. His interest in trap-building has turned into an ''obsession''.
* GadgeteerGenius: In ''What's New, Scooby Doo?'', Fred at least comes close with his improbably sophisticated modifications to the Mystery Machine.
* TheGenericGuy: Former TropeNamer. He was the least interesting member of the cast in the original series, but later portrayals of him avert this, usually making him goofy and naive. Being TheHero also makes him the StandardizedLeader.
* TheHero
* IconicItem: He will defend his (outdated even at the time it was introduced) orange ascot vigorously against any fashion police who mocks it.
* TheLeader: Type II/IV primarily, and a subtle Type III that gets {{Flanderized}} and parodied in later installments.
** StandardizedLeader: See TheGenericGuy.
** SupportingLeader: He may be the leader, but he isn't the main character.
*** Except in ''WesternAnimation/ScoobyDooCampScare'', which is something of ADayInTheLimelight for him.
* ObliviousToLove: In some incarnations like ''WesternAnimation/ScoobyDooMysteryIncorporated'' Fred is a teenager with only one thing on his mind. Unfortunately for Daphne, that something happens to be "solving mysteries and building traps!"
* ProperlyParanoid: In ''A Pup Named Scooby-Doo''.
* PutOnABus: In the 1980s era productions, Fred left the group to open an actual solo private investigator business, that is implied to not have gone well. See CluelessDetective above.
* RedHerring: In ''WesternAnimation/APupNamedScoobyDoo'', a kid named [[TheBully Red]] [[MeaningfulName Herring]] was the culprit behind the first case the group ever solved, and Fred then accused him of every other crime they ever ran across.
* TookALevelInDumbass: See CluelessDetective and {{Flanderization}} above.
* {{Tuckerization}}: Fred is named for television executive [[http://en.wikipedia.org/wiki/Fred_Silverman Fred Silverman]], who helped with ''ScoobyDooWhereAreYou's'' development and subsequent broadcast.
* VocalEvolution: Fred has developed a Minnesotan accent as a result of the character's personality becoming increasingly goofier.

!Supporting Characters

->Voiced by:\\
Lennie Weinrib (1979-1980)\\
Creator/DonMessick (1980-1986)\\
Scott Innes (2002 Live-Action movie)

Scooby's more courageous nephew. The one who yells, "Let me at 'em!", when he sees the MonsterOfTheWeek. To prevent spoilers, some of Scrappy's tropes from the 2002 movie ''Film/ScoobyDoo'' are not listed here.

Scrappy is famous as the TropeNamer for TheScrappy. But that's an audience reaction, and belongs in our [[YMMV/ScoobyDoo YMMV section]].
* BrooklynRage: In his earliest appearances he had a definite Brooklyn accent, which was toned down after a while.
* CatchPhrase: "Da-da-da-da-da-da, Puppy Power!" and "Let me at 'em, Let me at 'em!"
* CousinOliver: Scrappy was not in the original cast, but joined later. He is much smaller (and so we presume, much younger) than Scooby, Shaggy, or the rest of the original cast.
* {{Expy}}: Of Henery Hawk, FoghornLeghorn's pint-sized predator from ''WesternAnimation/LooneyTunes'', according to Mark Evanier.
* KidAppealCharacter: A famously unpopular one.
* LeeroyJenkins: "Let me at 'em, I'll splat 'em!" Scooby prefers to run away, but Scrappy likes to charge in and yell at the monster.
* LetMeAtHim: His CatchPhrase.
* MouthyKid: Mouthy Puppy, who talks far more often than Scooby does.
* {{Nephewism}}: Scooby suddenly has a nephew. Scrappy often talks about "Uncle Scoob".
* PintSizedPowerhouse: He ''is'' able to lift Scooby and Shaggy with one hand.
* SmallAnnoyingCreature: The most that Scrappy can do is annoy the monster, because Scrappy is no real threat.

->Voiced by DawsButler
* CatchPhrase: "Dum dum dum DUM!" (from LudwigVanBeethoven's ''Fifth Symphony.'')
* DeepSouth

* TakeThat: An episode of ''WesternAnimation/ScoobyDooMysteryIncorporated'' has said he's in prison for 25 years for his crimes.

* DarkSkinnedRedhead: Dusk.
* DarkIsNotEvil: They dress in dark clothing, wearing vampire fangs, and have bat stickers on their instruments and yet, they're environmentally friendly rock stars with hearts of gold.
* {{Expy}}: They are essentially a CaptainErsatz of JosieAndThePussycats with a coat of {{goth}} and ecofeminist paint.
* GirlishPigtails: Dusk
* GranolaGirl
* OnlyKnownByTheirNickname: Well, Thorn, Dusk and Luna are StageNames. Only Thorn's real name was revealed in ''WesternAnimation/ScoobyDooAndTheWitchsGhost'' (Sally [=McKnight=]).
* PerkyGoth
* ThePowerOfRock
* SoapBoxSadie

!! Monsters and Ghosts
* AmbitionIsEvil: In the Scoobyverse, changing one's life means taking some frightening extremes.

* BedSheetGhost: Three! The Phantom of Vazquez Castle, the ax-wielding phantom from "Haunted House Hang-Up", and the Ghost of Scooby Manor in "Scooby's Roots" [[spoiler:which, bizarrely, turned out to be a real ghost in a costume]].
* BigfootSasquatchAndYeti: The Snow Ghost is the ghost of a deceased Yeti, and the ghost of Bigfoot showed up, too.
* BlobMonster: Several. The Gloppy Green Ghost, the Wax Phantom, the Cheese Monster ([[SincerityMode seriously]]), the Tar Monster, the Mud Monster, and the Creature from the Chem Lab.
* BlowYouAway: The Windmakers.
* CoDragons: The Hooded Zombies to Zentuo in "Mystery Mask Mix-Up".
* CoolShip: Space Kook's UFO is a floating tennis birdy.
* CutLexLuthorACheck: A few can fall under this if their effects skills are particularly good, but the biggest offender is probably the Creeper. He robs a bank overnight...when he's the bank president and should therefore be very rich.
* TheCameo: Several of them appear in ''Mystery Incorporated'' as displays in the Crystal Cove spook museum. The Creeper also shows up in a flashback,[[spoiler:which[[RetGone never happened]] thanks to Scooby killing the Nibiru Entity.]]
* EvilChef: The ghosts of Chefs Maras and Pierre [[IncrediblyLamePun Ghoulache]].
* EvilIsHammy: If they talk, this is usually guaranteed.
* EvilLaugh: The Space Kook has an awesome one.
* FromNobodyToNightmare: Quite a few turn out to be people with rather humble occupations.(Caretakers, Farmers, Fishermen,etc.)
* GiantFlyer: The Giant Vulture, the Willawaw, and the Wakumi.
* GracefulLoser: Unlike the other villains from the original series, Bluestone The Great doesn't show much resentment toward the Gang for foiling his plans. Rather, he proudly demonstrates how he was able to pull off such convincing illusions, not even uttering the famous "Meddling Kids" line.
* Greed: The most common motivation of all.
* JekyllAndHyde: A monster from the original series. [[spoiler: It turns out that "Hyde" is actually just Jekyll in a suit]]. Hyde is also the main disguise of the villain from the Creator/SandyDuncan episode.
* ItsAllAboutMe: Terrorizing people and stealing property is never a problem for them.
* LaughablyEvil: The Ghost Clown and the Phantom of Vasquez castle are clearly having a lot of fun messing with the gang.
* LegionOfDoom: Different teams of them appear in ''Cyber Chase'' and ''Monsters Unleashed''.
* LittleGreenManInACan: Space Kook seems to be a floating skull contained in a space suit. In ''Mystery Incorporated'', this outfit gets stolen and used by another(much smaller) fake alien.
* MalevolentMaskedMen: Pretty much all of them turn out to be this, but some deliberately use this look, such as the two "Witch Doctors" and Old Iron-Face.
* MasterOfIllusion: Some of them pull off some pretty complicated effects to maintain their facades. Justified with the Phantom of Vasquez, as he's a stage magician.
* MonsterClown: The Ghost Clown. A later episode even had a ''giant robot'' clown.
* MonsterOfTheWeek
* MultipleHeadCase: Boogedy Bones. He even has one on his foot!
* NinjaPirateZombieRobot: Chickenstein!
* YouMeddlingKids: TropeNamer.
* OurDragonsAreDifferent: The gang has faced both Western and Eastern dragons.
* OurMonstersAreWeird: More and more so each new iteration.
* OurVampiresAreDifferent: Actually, they're all pretty classic.
* OurWerewolvesAreDifferent: The one haunting Franken Castle was pretty normal for a werewolf, but the next one was an ''undead'' werewolf.
* RealAfterAll: The zombies from ''Zombie Island'' and the entire monstrous cast of the first ThreeShorts series.
** And in some later direct-to-video movies.
* SamusIsAGirl: Gator Ghoul and Old IronFace.
* ScoobyDooHoax: These guys are the TropeNamer.
* SkullForAHead: Space Kook.
