[[caption-width-right:184:Yeah, they made a video game out of it.]]

-->''My computer screen is my enemy...''

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. It the last movie to be animated by Creator/MookDLE, and using the character designs of the [[WesternAnimation/ScoobyDooOnZombieIsland previous]] [[WesternAnimation/ScoobyDooAndTheWitchsGhost three]] [[WesternAnimation/ScoobyDooAndTheAlienInvaders movies]]. It was also the final time Scott Innes voiced both Scooby-Doo and Shaggy (though he sometimes returned afterword for commercials and video games), and the final time Creator/BJWard did the voice of Velma. However, it marked the first time Creator/GreyDeLisle voiced Daphne following the passing of Creator/MaryKayBergman. This was also the very first ''Scooby-Doo'' project produced entirely digitally, though ''Alien Invaders'' had a few digital sequences and effects.

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: [[UsefulNotes/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?

Oh, and the film [[RecursiveAdaptation had a video game adaptation]] for original UsefulNotes/PlayStation and UsefulNotes/GameBoyColor which sold well and became a "Greatest Hits" later on.
!! This is a list of the following Tropes this movie provides examples of:
* AchillesHeel: Despite being quite dangerous, the Phantom Virus can be subdued if a magnet is held near him, Bill [[LampShade lampshades it]] by stating it works on him like "Kryptonite on {{Superman}}". We also get a literal example when the Virus steps on a magnet and injures his heel.
** The Cyber Gang also share this weakness as they're also made of "electromagnetic energy".
* AgentScully: Officer Wembley before the gang are blasted into the game disbelieves there is a real phantom and thinks it's a prank. Justified in that he hasn't seen the phantom.
* AncientEgypt: Level 7.
* AIIsACrapshoot: The Phantom Virus may or may not be an example of this: it's unclear exactly how much of his behavior was things he decided on his own and what [[GoneHorriblyRight he was doing because he was programmed to]].
* 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.
* AuthorAppeal: InUniverse. The creator of The Phantom Virus gets caught because [[spoiler: he couldn't resist programming his love of baseball into it.]]
* BalloonBelly: Scooby and Shaggy after eating all the food in the cafeteria.
** BigEater
* BigNo: [[spoiler: The Phantom Virus utters one as he disintegrates right after Scooby beats him by getting the last box of Scooby Snax.]]
* BenevolentAI: 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.]]
* BlobMonster: Guess who's back? [[spoiler: The Tar Monster!]]
* TheBusCameBack: All of the previous monsters come back in the final level.
* ButNowIMustGo: The gang leaves their clones for the real world.
* 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.
** The game adaptation has Charlie, the Funland Robot from the original series as the penultimate boss.
* 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.
* ElectronicSpeechImpediment: As he yells his [[spoiler: BigNo after his defeat, the Phantom Virus' voice slows down, deepens and devolves into a groan.]]
* 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.]]
* ForgottenSuperweapon: Only in the final level does Shaggy realize he still has the magnet Professor Koffman gave him which they can use against the Phantom Virus.
-->'''Shaggy:''' I guess I was too busy being scared!
* 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. Fittingly enough, he's also this in the game of the movie.
* 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.
* JerkWithAHeartOfGold: Officer Wimbley is pretty hostile to the gang when they arrive on the campus and remains so until they enter the game. Once it happens, Wimbley immediately asks if there's a way to save them, proving that he really is dedicated to his job despite his abrasive nature.
* 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, both on the plan itself ''and'' the placement of which members split-up into what groups (Shaggy with Scooby, Fred with Velma and Daphne), indirectly on the latter.
---> '''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.]]
* NotAMask: Scooby and Cyber-Scooby try this on the Gator Ghoul.
* 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.
* ShockAndAwe: The Virus has this power.
* SuperNotDrowningSkills: In level four, the gang first appears underwater in their normal clothes, but a few seconds later diving equipment generates on them. Although just before it generates they have trouble breathing.
* SympatheticInspectorAntagonist: Officer Wembley at first plays an antagonistic role to the gang, suspicious of them and forcing Fred, Daphne and Velma to go with him to the lab. Justified, in that they were behaving oddly. He is even suspected of being a DirtyCop, considering he was in the lab when the gang were blasted into the game. [[spoiler:He isn't and even helps arrest the real villain.]]
* 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.
** Probably justified considering this is a video game.
* 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.
