[[caption-width-right:184:Yeah, they made a video game out of it.]]
The fourth installment in the series of ScoobyDoo DirectToVideo films, '''''Scooby-Doo and the Cyber Chase''''' was produced by [[Creator/WarnerBros Warner Bros. Animation]] yet still carries a [[Creator/HannaBarbera Hanna-Barbera Cartoons, Inc.]] copyright and itís considered as the last official movie by absorbed Creator/HannaBarbera after the passing of founder and creator William Hanna. Not only was it the last movie to be animated by Creator/MookDLE, but it was also the last time Scott Innes voiced both Shaggy and Scooby, as Creator/CaseyKasem returned voicing Shaggy until the [[WesternAnimation/ScoobyDooAndTheSamuraiSword thirteenth]] {{direct to video}} and Creator/FrankWelker took over for the voice of Scooby, though Innes (supposedly) does the voices of both in video games. Music/GreyDeLisle takes over the voice of Daphne following the passing of MaryKayBergman, though she wouldn't officially take over the role until three movies later.

Eric, a video game designer, has just created a new game based on none other than his friends Mystery Incorporated. However, one night, while he, his best friend and lab partner Bill, and his teacher, Professor Kaufman, are testing out a new laser they built to enter in the science fair, the laser beams a phantom virus from cyberspace into the real world. The virus breaks Eric's arm, but before it can do further harm, Professor Kaufman scares it away with a magnet lying nearby.

The next day, Mystery Inc. arrives at the college, and Eric tells them the story, and that the phantom virus is currently running around the campus causing mayhem. They agree to help their friend by [[LetsSplitUpGang splitting up]] and searching for the virus, each equipped with a special magnet that they hope they can use to destroy the virus with. Eventually, Shaggy and Scooby get tired of looking around, and take a break in the cafeteria. Of course, that's where the virus finds them at, and Scooby, Shaggy, and the virus have a classic ScoobyDoo chase with a remix of the original theme song in the background.

Fred, Daphne, and Velma, caught in the basement "snooping around" by Officer Wembley, are forced by Wembley to stay put with him in the lab until Professor Kaufman gets back. However, Scooby and Shaggy burst through the door with the virus on their tails. The gang runs aimlessly around the lab for about a minute, until they all collide in one location. Convenient for an unknown somebody, because right then, the laser is fired at the gang, and they're transported into cyberspace, and into the game Eric made based on their adventures.

Inside the game, there are ten levels:
* Level 1: The moon, which includes moon ghosts as enemies.
* Level 2: [[TheRomanEmpire The Roman Empire]], equipped with an army of skeleton warriors, and a lion to top it all off.
* Level 3: [[OneMillionBC Prehistoric Era]], where the gang must find shelter away from things like, well, dinosaurs.
* Level 4: The Ocean. There's some mackerels, a school of yellow fish, a sunken pirate ship... Oh! And a shark.
* Level 5: A backyard. Seems safe enough, until you realize the gang's not even an inch tall.
* Level 6: [[JidaiGeki Feudal Japan]], where there's a [[WesternAnimation/ScoobyDooAndTheSamuraiSword Samurai Warrior]] that must be fought.
* Level 7: AncientEgypt, which includes mummies and camels.
* Level 8: [[MedievalEuropeanFantasy Medieval Europe]]. You must [[DamselInDistress save the princess]] by defeating the dragon.
* Level 9: The Arctic, with a less than friendly polar bear.
* Level 10: [[TheCity A full scale city]]. It's also where the cyber versions of the gang usually prefer staying. Beating it will [[FridgeLogic bump them back to Level 1.]] Also filled with a RoguesGallery of past costumed villains, only the digital versions are ''real'' monsters.

In each level, there is a hidden box of [[WouldYouDoItForAScoobySnack Scooby Snacks]] that need to be obtained before you are automatically transported out of the level and into the next. Pretty neat, eh? In order to survive, the gang must make it through all ten levels. However, all throughout the game, the danger they face is real. And guess who decided to join them in the game?
!! This is a list of the following Tropes this movie provides examples of:
* AIIsACrapshoot: The Phantom Virus.
** A benevolent version seems to be the Cyber versions of Mystery Inc., who have obtained enough awareness to realize beating the game just puts them back on Level 1, and they like Level 10 so long as they stay out of the parts of the level were the monsters are. However, they're also just as compassionate as the ''real'' Mystery Inc. and gladly offer to do that to defeat the Phantom Virus and help them. [[spoiler:They also wave to their real life counterparts when they prepare to play the game.]]
* AncientEgypt: Level 7.
* AntiSneezeFinger: Scooby Doo pulls one of these on Cyber Scooby so that they don't give their position away to [[spoiler: Jaguaro.]] [[{{Irony}} Then he sneezes]].
* ArtisticLicensePaleontology: Mammoths and Dinosaurs did not exist in the same era. This is [[LampshadeHanging lampshaded]] by Velma.
* AttackOfThe50FootWhatever: Level 5 has them in a giant field of grass and a humongous ant chasing after them.
* BalloonBelly: Scooby and Shaggy after eating all the food in the cafeteria.
** BigEater
* BlobMonster: Guess who's back? [[spoiler: The Tar Monster!]]
* TheCity: Level 10.
* ClonesArePeopleToo: The gang seems to care about their clones as if they were real people, not just computer generations.
* ContinuityNod: A potentially unintentional one. Shaggy says that "It's bad enough that we're always chasing real ghosts." Perhaps referencing their earlier movies.
** More specifically, the last level features 5 classic (though sometime obscure) monsters from the original shows.
* CoversAlwaysLie: You can't run in and out of the computer like that, Fred, Daphne and Velma never get trapped in whatever that is, and the city isn't green. When the level generates, the sky is only green for a brief moment, then it disappears.
* EnergyBeing: The Phantom Virus.
* EverythingsBetterWithDinosaurs: The prehistoric level's got the Phantom Virus riding a T-Rex.
* EverythingsBetterWithPrincesses: Along with the dragon, a princess appears in level 8, whom Shaggy saves, [[IgnoreTheFanservice but leaves her tied to the tree she was stuck on.]]
* EverythingsBetterWithSamurai: Level 6.
* EvilLaugh: The Phantom Virus.
* FangsAreEvil: [[spoiler: Jaguaro]]
* {{Foreshadowing}}: Level six involves fighting a samurai warrior, who happens to look a lot like the Black Samurai from ''WesternAnimation/ScoobyDooAndTheSamuraiSword''.
** Not to mention ''WesternAnimation/ScoobyDooLegendOfThePhantosaur'' and level 3 both involved dinosaurs. Someway or another.
** Let's not forget that there was an Egyptian level, and eventually an Egyptian movie, ''Where's My Mummy.''
** In-universe for the movie we have [[spoiler:the Phantom Virus' baseball references.]]
* FinalBoss: It's unknown if there was one programmed into the game originally ([[spoiler:the LegionOfDoom formed from the monsters the gang faced may count]]), but the Phantom Virus essentially takes this role on himself at the end of the game.
* GoneHorriblyRight: The Phantom Virus. Though [[spoiler: it's unknown how Bill thought the virus would act like once it was created.]]
* TheGoomba: The Moon Ghosts were probably intended to be this, but were made more threatening with the Phantom Virus with them.
* HeroicDog: Scooby Doo saves a baby pterodactyl.
* HoistByHisOwnPetard: [[spoiler: Bill outs himself as the perpetrator by having the virus reference baseball one too many times. Which clues the gang on to him as he mentioned earlier he was a baseball fan.]]
* IgnoreTheFanservice: After Shaggy defeats the dragon, he ignores the princess and grabs the bag of Scooby Snacks she was holding, even though ''she was trying to kiss him.'' And she wasn't a bad looking princess either.
* InstantAwesomeJustAddDragons: In level 8, Shaggy manages to defeat one. Albeit, it wasn't very hard.
* JidaiGeki: Level 6.
* KryptoniteFactor: The Virus has this towards magnets.
* LavaAddsAwesome: Level 3. The Scooby Snacks are found in a nest of pterodactyls resting on an erupting volcano.
* LegionOfDoom: [[spoiler:Level 10 has a small army of the gangs' old foes guarding the Scooby Snacks. The Creeper, Jagwaro, Gator Ghoul, The Tar Monster and Old Ironface. It's unknown if the designer originally intended them to be a unified force, but the Phantom Virus takes charge and leads them ''all'' against the gang.]]
* LetsSplitUpGang: [[LampshadeHanging Lampshaded]] by Shaggy.
---> '''Shaggy''': Like, do we ever do it any other way?
* LighterAndSofter: Compared to the past films, this one balances out the comedic element much further, but it's still quite enjoyable, especially knowing it pays tribute to its roots. It's also the first installment of ''Scooby-Doo'' to use digitally-inked animation. Sadly, the next string of films after this one contract {{Sequelitis}}- the animation quality plummets and the edgy feel is all but abandoned.
* MakeMyMonsterGrow: Level 5 takes place in a giant backyard, filled with giant ants.
* MeetYourEarlyInstallmentWeirdness: The computer-generated Mystery Inc are based on the ''ScoobyDooWhereAreYou'' character designs. The computer-generated Shaggy wears the magenta shirt from 13 Ghosts of Scooby Doo and the trilogy of movies with Scrappy in them.
* MedievalEuropeanFantasy: Level 8.
* NeverSmileAtACrocodile: In level 10, [[spoiler: Gator Ghoul]]
* NintendoHard: InUniverse, the final level was so tough, that even it's ''designer'' can't beat it. And that was ''before'' the Phantom Virus took it upon himself to become the FinalBoss. [[spoiler:It takes the real Mystery Inc and their digital selves together to finally beat it.]]
* OneMillionBC: Level 3.
* PteroSoarer: In level 3.
* ReptilesAreAbhorrent: [[spoiler: Gator Ghoul.]]
* TheRomanEmpire: Level 2.
* ScoobyDooHoax: All staged by [[spoiler: Bill. He created the Phantom Virus to sabotage Eric's chances of winning the big cash prize at the science fair out of jealousy that Eric was more recent a student that he was, but Professor Kaufman liked Eric's game more.]]
** Played with, however, in that the Phantom Virus ''is'' real and very dangerous. He just happened to have been created to carry out one of these.
* ShiftingSandLand: Level 7.
* SuperNotDrowningSkills: In level four, the gang first appears underwater in their normal clothes, but a few seconds later diving equipment generates on them.
* TakenForGranite: Velma [[spoiler: and her cyber double try this with Old Ironface in wax.]] Unfortunately, he broke out of it.
* {{Technopath}}: The Phantom Virus.
* ThreateningShark: Level 4.
* TyrannosaurusRex: Level 3.
* WalkIntoCameraObstruction: With the Phantom Virus as he is slowly walking towards Eric, Bill and the professor.
* WaterIsBlue: That ocean in level four is a little too light.
* WhoWouldWantToWatchUs: The ScoobyDoo video game that Eric created.
* WouldYouDoItForAScoobySnack: The object of the game is to collect the snacks to advance to the next level. Unfortunately for Shaggy and Scooby, the box of snacks disappears before any can be eaten.
* YankTheDogsChain: The box of Scooby Snacks disappear before it can be opened or eaten.
** ThrowTheDogABone: Once Scooby gets the last box, he's able to have some of the snacks before he returns to the real world.
