History Film / ScoobyDooMonstersUnleashed

* MaleGaze: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that gives him a "Chick's body," which involves having CurvesInAllTheRightPlaces. In addition to his body, both his clothing and the filmmaking lean into several AlwaysFemale tropes. This includes GenderedOutfit, BareYourMidriff, and FormFittingWardrobe for Shaggy's new clothes, as well as BoobsAndButtPose, WomenAreDelicate, and GirlyRun for Shaggy's choreography and blocking while in this form.

* TemporaryBulkChange: While in Jonathan Jacobo's underground laboratory, Scooby and Shaggy drink various chemicals/potions that cause them to transform, often changing mass considerably. Because each potion cancels out the effects of the previous potion, this change in mass is only temporary.
* TheStinger: Scooby [[CelebrityParadox is playing the Game Boy Advance game based on the movie]] and shows the viewers a secret code to use in the game. [[spoiler:Entering it in the GBA game, among other things, shows the game's true ending, which is similar to the film's. It can be used in other versions as well -- using it at the end of the PC game takes the player to a bonus level, which is a five-round dance off with the Evil Masked Figure.]]

* IJustWantToBeBadass: A subplot in the film is how Scooby and Shaggy want to stop being TheLoad for the rest of Mystery Inc.

* BladeOnAStick: Daphne uses a halberd when dueling the Black Knight. Also qualifies as AnAxeToGrind.

* PunctuatedForEmphasis: Before Scooby [[spoiler:resets the control panel to the machine]], he says, "Scooby... Dooby... '''Doo'''!!!!!"

--> '''Freddie:''' Hey! You're doing that thing again where you take everything I say out of context. You're trying make it look like I think Coolsville sucks! [''realises he's being filmed''] No! Don't record that!

''Scooby-Doo 2: Monsters Unleashed'' is the 2004 sequel to the 2002 live action movie ''[[Film/ScoobyDoo2002 Scooby-Doo]]'', directed by Raja Gosnell and written by Creator/JamesGunn.

This was the final live-action Creator/HannaBarbera adaptation to be overseen by co-founder Joe Barbera, who died a year later.

* ActorAllusion: Daphne uses {{Buffyspeak}} while attacking the 10,000 Volt Ghost. Her actress, Creator/SarahMichelleGellar, previously portrayed the titular character in ''Series/BuffyTheVampireSlayer''.

* ATragedyOfImpulsiveness: While searching for an antidote in Jonathan Jacobo's underground laboratory, Shaggy spills a potion on his hand. He knows that the potion may be dangerous to consume, because Scooby already drank one and transformed into a monster, but rather than wipe the liquid off, he licks it off and winds up transforming as well.

* BeYourself: The film has a subplot of Scooby and Shaggy trying to be more like Fred, Daphne, and Velma in hopes that doing so will enable them to solve the mystery on purpose for a change. Velma eventually explains to the two that they don't need to change and are a vital part of the team just the way they are.

* BrainBleach: [[spoiler:Ned the cameraman knew who the Evil Masked Figure was. What he doesn't know, however, is that she is a ''he''.]]

* {{Buffyspeak}}: Also counts as ActorAllusion for Daphne.

-->'''Shaggy:''' Scooby-Doo, you've turned into a freaky monster!
-->'''Shaggy:''' I've got a chick's body!
-->'''Scooby:''' I'm a Tasmanian Devil!
-->'''Shaggy:''' Check it out, dude! I'm buff.
-->'''Scooby:''' It seems as if I've become ludicrously intelligent!

* ContinuityNod: In the cartoon, Captain Cutler was defeated by having a vehicle crash into him. In the film, he's also defeated by having a vehicle crash into him.
* ContinuityNod: In "Scooby-Doo and a Mummy, Too!" which is Season 1, Episode 12 of "Scooby-Doo, Where Are You?" Shaggy has his back turned while Scooby drinks a yellow chemical and transforms, just like Jonathan Jacobo's underground laboratory in this film.

* DoesThisRemindYouOfAnything: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that makes him abnormally muscular. Because MusclesAreMeaningful, images of this form were used for the "Ultra Instinct Shaggy" meme, a meme in which Shaggy has superhuman, Goku-like powers. This adds an extra layer of comedy to the original scene.

--->'''Fred''': And the real identity of [[spoiler:Ned]]] is--
--->[''Fred tugs at [[spoiler:Ned]]'s hairline; nothing happens'']
--->'''[[spoiler:Ned]]''': Ow!
--->[''{{beat}}'']
--->'''Fred''': ...[[spoiler:Ned]]!

* DroppedGlasses: Velma -- [[RunningGag again]] -- does this towards the climax. She even lampshades it, remarking, "I have ''got'' to consider contact lenses." Fortunately for Velma, her glasses are soon picked up by Patrick.

* EleventhHourSuperpower: During the FinalBattle, Scooby combats the Tar Monster with a fire extinguisher he finds.

* HaughtyHmph: The Pterodactyl Ghost has its [[BadassArmFold arms crossed]] and is drumming a finger and giving a [[SmugSmiler smug smile]] when the gang's curtain & ropes trap just slips off it.

* IJustWantToBeBadass: A subplot in the film is how Scooby and Shaggy want to stop being TheLoad for the rest of Mystery Inc.

* NiceJobBreakingItHero: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that causes him to transform into a monster. Shaggy tries to find an antidote, but winds up accidentally transforming himself as well.
* NiceJobBreakingItHero: When Shaggy and Scooby find a control panel, they start fiddling with it. This causes four monsters to be unleashed: a [[OurZombiesAreDifferent zombie]], [[EliteMooks Captain Cutler]], [[KillItWithFire Miner 49er]], and the [[OneManArmy Tar Monster]].

* ThemeMusicPowerUp: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that makes him abnormally muscular and the song "Get Ready For This" by 2 Unlimited plays.
* ThemeMusicPowerUp: Happens in the climax with MXPX's cover of the theme song playing.

* TheseAreThingsManWasNotMeantToKnow: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that makes him ludicrously intelligent, and immediately after acknowledging this, he complains, "It's awful! Oh, I long for the blissful ignorance of my former self!" because he feels cursed by his newfound knowledge.
* ThinkingOutLoud: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that makes him ludicrously intelligent. He also becomes much more talkative, monologuing about his feelings and plans.

* VillainExitStageLeft: [[spoiler:The Evil Masked Figure attempts to escape after his scheme falls apart, only to fall through the catwalk.]]
* MenAreStrongWomenArePretty: For the most part, this is the case throughout the film, with the only exception being Daphne, who is both conventionally attractive (in accordance with HollywoodBeautyStandards) and strong. Shaggy's transformations in Jonathan Jacobo's underground laboratory overtly reflect this dichotomy, with his feminine form being slim and conventionally attractive (in accordance with HollywoodBeautyStandards), with CurvesInAllTheRightPlaces, and his masculine form being abnormally muscular.

-->'''Fred:''' This is bad!
-->'''Shaggy:''' No doubt.
-->'''Fred:''' Shaggy?
-->'''Shaggy:''' Yeah?
-->'''Fred:''' Who's driving?
-->'''Shaggy:''' Uh...
-->''[the gang looks behind and notices that Scooby is the only one sitting in front]''
-->'''Scooby''': ''[completely nonplussed]'' Hello.

* BigNo: The Evil Masked Figure [[spoiler:after Scooby puts the control panel back in the machine and before the monsters start dying.]] They let out another as they are unmasked, that changes from the Evil Masked Figure's voice into [[spoiler:Heather Jasper-Howe]]'s voice once the mask comes off.
* BigNo: While in Jonathan Jacobo's underground laboratory, Scooby attempts to create an antidote using two potions. Shaggy throws one of the potions across the room and Scooby shouts, "Nooo!"

--> '''Freddie:''' Hey! You're doing that thing again where you take everything I say out of context. You're trying make it look like I think Coolsville sucks! [''realises he's being filmed''] N-no, wait! Don't record that!

* Canine Companion: Scooby is Shaggy's NonHumanSidekick.

* EasySexChange: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that gives him a "Chick's body," but has no effect on his head, making it a PartialTransformation, and making this form a ButterFace.

* FakingTheDead: [[spoiler:The gang actually catches on so quickly that Jonathan Jacobo may be the villain they're after from the clues: he did have designs of a machine that can create real monsters, ''and'' it was his alter-ego, the Pterodactyl Ghost, that attacked the museum and set the whole thing in motion. The only reason they brush this aside is because Jacobo is believed dead after attempting to escape prison.]]

* {{Foreshadowing}}: If you can understand Daphne's "incoherent babble" when she confronts Heather Jasper-Howe, you'll realize [[spoiler:she's figured out that Howe is actually the Evil Masked Figure]].

* {{Foil}}: The Faux Ghost to [[spoiler:Jonathan Jacobo]]. While the patrons of The Faux Ghost are still bitter about being unmasked, they also saw the error of their ways and are trying to go straight and turn their lives around (though in Jeremiah Wickles' case, he is still not a good man, as shown by his plan for a gold mining camp). [[spoiler:Jonathan Jacobo]], however, let his bitterness draw him down an even darker path of revenge, and as a result is probably going to jail for an even longer time than he was originally.
* ForcedTransformation: While in Jonathan Jacobo's underground laboratory, Scooby and Shaggy toss potions at each other, attempting to force a transformation. Shaggy tosses a potion at Scooby in his Tasmanian Devil form, and Scooby tosses a potion at Shaggy in his abnormally muscular form.

* IgnoreTheFanservice: While in Jonathan Jacobo's underground laboratory, Shaggy drinks a potion that gives him a "Chick's body," but rather than pulling a ManIFeelLikeAWoman and exploring his anatomy- like Fred does while in Daphne's body in "Scooby-Doo" (2002)- Shaggy verbally acknowledges his new form while pointing to his GagBoobs and then just continues searching for an antidote.

* CaptainObvious: While in Jonathan Jacobo's underground laboratory, Scooby and Shaggy drink various chemicals/potions that cause them to transform in various ways, and for each transformation, one or both of them explains how they've transformed.

* KarmicTransformation: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that causes him to transform into a monster, which is ironic because he's deeply afraid of monsters. This could be interpreted as punishment for Scooby's gluttony, as it's a direct result of him eating first and asking questions later. This is further supported by his the design of his monstrous form, which features big, raised, EyeOnAStalk eyes for spotting food at a distance, six BizarreAlienLimbs for grabbing several foods at a time, and a BalloonBelly for storing large quantities of food.

* UglyCute: While in Jonathan Jacobo's underground laboratory, Scooby drinks a potion that causes him to transform into a monster, but despite his monstrous features, he retains his PuppyDogEyes and is generally soft in his appearance.
