Scooby-Doo 2: Monsters Unleashed is a 2004 video game based on the film of the same name. It was released on both the Game Boy Advance and PC.
Scooby-Doo 2: Monsters Unleashed provides examples of:
- Adaptational Badass: Daphne fights the Pterodactyl Ghost, the Black Knight's Ghost and the 10,000 Volt Ghost while Scooby fights the Miner 49er and the Evil Masked Figure in the Game Boy Advance Version.
- Adaptational Intelligence: In the Game Boy Advance version, Daphne punches at the 10,000 Volt Ghost rather than directly and beats him by hitting falling objects at him.
- Adapted Out: The PC version omits Old Man Wickles, Patrick Wisely, Aggie Wilkins, the 10,000 Volt Ghost, and Dr. Jonathan Jacobo. The Game Boy Advance version also leaves out multiple characters and lines of dialogue.
- Ass Kicks You: How Shaggy attacks enemies in the GBA version.
- Decomposite Character: Heather Jasper Howe and the Evil Masked Figure are separate characters in the PC version, neither of them being disguises of the Adapted Out Dr. Jonathan Jacobo.
- Demoted to Extra: Old Man Wickles only appears for a minigame (Sneaky Shaggy) and the following cutscene in the Game Boy Advance version and Heather Jasper Howe only appears in cutscenes in the first area and the ending.
- Final Boss: The Game Boy Advance version ends with a boss fight against the Evil Masked Figure.
- Gameplay and Story Segregation: The game's usage of the most of the movie plot for the cutscenes results in this such as Scooby and Shaggy beating the Miner 49er by using Scooby's fart to blow his flames back in his face despite Scooby just having wrapped up a Boss Battle against the Miner.
- Hyperactive Metabolism: Carrots and Hamburgers heal Scooby, Shaggy and Daphne in the Game Boy Advance version.
- Multiple Endings: The Game Boy Advance version has two different endings depending on whether the player has inputted the correct code in the scene where the Evil Masked Figure is unmasked. Using the incorrect code has the ending cutscene avoid showing the Evil Masked Figure's true identity and only Mystery, Inc.'s reactions to the villain's unmasked self, their only statements being disbelief at who the Evil Masked Figure truly is. Inserting the correct code, "SD2", will have the villain unmasked as being Dr. Jonathan Jacobo like in the movie.
- Status Effects: In the GBA version, Shaggy can throw Green Goo to slow monsters and make them easier to beat and Scooby can throw Magnifying Glasses to shrink foes both starting in area 3.
- The Voiceless: The Skeleton Men do not talk.
- Wolfpack Boss: The Skeleton Men boss battle in the GBA version is Shaggy vs 30 Skeleton Men.
- You Meddling Kids: Said by the Evil Masked Figure in the PC version as well as the voice of Wickles Manor.
