'''''Scooby Doo 2: Monsters Unleashed''''' is the 2004 sequel to the 2002 live action movie ''Film/ScoobyDoo''.

Mystery Inc. is attending the grand opening of a museum based on their adventures and the monsters they caught. However, the celebration is cut short due to the Pterodactyl ghost attacking and stealing two different costumes. As it turns out, someone is using a machine to reanimate the monster costumes and turn them into real monsters.

The film was an even worse failure critically than the first, but some how managed to gross around $180 million. However, it ended up winning a Golden Razzie Award for "Worst Remake or Sequel."

!''Scooby-Doo Monsters Unleashed'' provides examples of:
* {{Badass}}: Some of the monsters, such as the Pterodacyl, Black Knight, and Tar Monster are surprisingly impressive. Mystery Inc themselves are pretty badass for suriving and defeating a number of them.
* BigNo: The Evil Masked Figure as they are unmasked.
* BlindWithoutEm: Velma, naturally. This time it's somewhat downplayed, as even after she [[DroppedGlasses loses them]], she's still able to make out [[spoiler:Patrick's StalkerShrine to Jonathan Jacobo, as well as the photograph showing [[NotQuiteDead the supposedly dead Jacobo]] outside the half-finished Coolsonian Museum]].
* BrainBleach: [[spoiler:Ned the cameraman knew who the Evil Masked Figure was. What he doesn't know, however, is that she is a ''he''.]]
* DramaticUnmask: Done [[spoiler:twice]] with the Evil Masked Figure, unmasking them as [[spoiler:Heather Jasper-Howe, then unmasking ''Howe'' as actually being Jonathan Jacobo in disguise]].
* DroppedGlasses: Velma drops her at one point towards the end of the film. She lampshades it, remarking, "I have ''got'' to consider contact lenses".
* ExpressiveMask: The Evil Masked Figure's mask. [[spoiler:And [[LatexPerfection the Heather Jasper-Howe mask they wear underneath it]]]].
* 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 brushed this aside was because Jacobo was 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]].
* GroinAttack: Velma delivers one to the Black Knight Ghost after determining that it is his only weakness.
* HeroWithBadPublicity: Courtesy of Heather Jasper-Howe.
* IJustWantToBeBadass: A subplot in the film is how Scooby and Shaggy want to stop being TheLoad for the rest of Mystery Inc.
* LatexPerfection: [[spoiler:Jacobo masquerading as Heather.]]
** Hilariously subverted immediately afterwards when Fred confronts [[spoiler:Jacobo's]] accomplice:
--->'''Fred''': And the real identity of Ned is... (pulls at Ned's hairline)
--->'''Ned''': Ow!
--->[{{Beat}}]
--->'''Fred''': ...Ned!
* LegionOfDoom: Several famous monsters Mystery Inc. have tackled become lackeys to the Evil Masked Figure.
* LetsSplitUpGang: When the group arrive at Wickles' mansion, it's ''Shaggy'' who says this (as part of his drive to be a better detective).
-->'''Shaggy''': Alright, gang! Let's, like, split up, and look for clues.
-->(the gang split up)
-->'''Fred''': [[LampshadeHanging He stole]] [[BuffySpeak my thing]] [[CatchPhrase that I say]]!
* MotorcycleJousting: Fred rides a motorcycle to duel a knight ghost.
* MythologyGag: When Scooby [[ItMakesSenseInContext finds the toilet brush in Wickles' mansion]], he and Shaggy start singing into it. The song? "Strangers In The Night" by Frank Sinatra, the song from which Scooby's name was derived.
* NeverFoundTheBody: When telling the gang about Jonathan Jacobo's failed prison escape, Velma explains that "his body was lost at sea". [[spoiler:Only it turns out Jacobo was NotQuiteDead]].
* OhCrap: the Cotton Candy Glob when he realizes that Scooby and Shaggy are NOT afraid of him. On the contrary...
** The Black Knight Ghost invokes this word for word when he notices that Fred and Daphne have just [=MacGyvered=] a way to defeat both him and the 10,000 Volt Ghost at the same time.
* OneManArmy: The Tar Monster can be this due to the nature of his powers, especially during the climax when [[spoiler:he single-handedly incapacitates all four human members of Mystery Inc]].
* PantyShot: Velma has one for a couple of frames as she jumps into a ship's air funnel.
* PaperThinDisguise: Shaggy and Scooby infiltrating [[BadGuyBar the Faux Ghost]] as "Shizzy McCreepy" and "SD McCrawley" respectively. Astonishingly, it works - right up until Scooby's afro flies off.
* RedHerring: [[spoiler:Velma's LoveInterest, Patrick, who has a StalkerShrine to [[BigBad Jonathan Jacobo]] located not far from the Masked Man's lair, and even admits to having admired the latter's work]].
** Also Jeremiah Wickles, who used to be the Black Knight.
