History Main / FakeCrossOver

* The "realness" of Nintendo Crossovers depends on where the franchises sit on the SlidingScaleOfSeriousnessVersusSilliness and it's possible for a crossover to be one-sided. ''VideoGame/KidIcarusUprising'' and ''VideoGame/MetalGearSolid'' are both games with very little regard for [[BreakingTheFourthWall the fourth wall]] but only the former references the events of ''VideoGame/SuperSmashBros''. Kirby meeting Samus in ''VideoGame/KirbysDreamLand3'' is a mandatory part of the game which needs to be done for OneHundredPercentCompletion, but it's unlikely the ''Franchise/{{Metroid}}'' series will ever acknowledge Samus' alleged trip to Popstar. She also never [[VideoGame/SuperMarioRPG slept in Peach's bed]], but Mario seeing her and Link is canon, because ''everything'' in the ''Mario'' franchise [[NegativeContinuity is canon]].

* Advertising/{{Progressive}}, an insurance company with plenty of advertisement, had an advertisement cross over with ''VideoGame/SonicTheHedgehog'' of all characters! Sonic can be seen speeding around in the set as Flo tells him all the ways Sonic can save on his insurance. The scene even uses the invincibility and extra life themes from ''VideoGame/SonicTheHedgehog3'', leading to many late Sonic fans who found the songs on Website/YouTube being surprised that the songs existed prior to the commercial.

* ''VideoGame/NelkeAndTheLegendaryAlchemistsAtelierOfANewLand'' brings together characters from the many different continuities of the ''VideoGame/{{Atelier}}'' series. However, these aren't the actual protagonists of past games being transported to this game's world, rather, they're characters who just happen to look and sound exactly like them while having lived in this universe all along.

** Amusing lampshade: A villain that first appeared in a Franchise/{{Batman}}''/''[[Comicbook/ThePunisher Punisher]] crossover turned up in ''Nightwing''. Nightwing had a rare memory lapse about the name of the other guy he met him with. ("Out-of-town psycho vigilante... want to say 'The Puncturer'? Something like that...")

** Another lampshade happens in the first Batman/Spider-Man crossover. Spidey mentions his allies the Avengers and the Fantastic Four, then says he keeps waiting for Superman to call him, then is cut off because Batman seems to take slight offense at that.
** It used to be a roughly-annual tradition, back in the 70's, for both the Franchise/{{Justice League|OfAmerica}} and Comicbook/TheAvengers to have a story taking place at the Rutland, Vermont Halloween parade. At least once, events in them influenced each other. It even spread to three other comic companies (Whitman, Charlton, and Warp). More info here: http://www.marvunapp.com/Appendix4/rutlandvt.htm

** Another amusing lampshade: After the ''DC vs. Marvel/Marvel vs. DC'' crossover, an issue of ''[[Franchise/JusticeLeagueOfAmerica Extreme Justice]]'' showed Comicbook/BlueBeetle stopping a villain using a sticky web substance. He proudly mentioned picking it up from [[Franchise/SpiderMan a guy who recently visited from another universe]]. This earns extra in-joke points because they're both bug-influenced heroes co-created by Creator/SteveDitko.

** G.I. Joe actually did this a few times. In Amazing Spider Man #268 (1985), Duke makes an unnamed appearance as head of a military unit assigned to carry out the wreckage of the Heroes for Hire building (which the Beyonder had turned into gold). It's the first item at the top of the page here: [[http://www.myuselessknowledge.com/joe/comics/gijxovers.html]] There was also a short story in Action Force (which G.I. Joe was known as in the UK) in which Quick Kick narrates the story of Shang Chi, Master of Kung Fu, and explains that Shang Chi was his master. Quick Kick describes Shang Chi as the greatest artist he's ever known and places him above Iron Fist, Batroc, and Elektra. This was done to introduce readers to the Master of Kung Fu reprints that would become a back-up feature in the Action Force comics. The story can be enjoyed here [[http://www.bloodforthebaron.com/comics/maf/005/index.html]]
** Similarly, an early issue of ''ComicBook/TheTransformersMarvel'' comics had the Autobots briefly teaming up with Franchise/SpiderMan, before later issues indicated that the Transformers were in a separate universe from most other Marvel comics. A few issues after Spider-Man teamed up with them, Ratchet traveled to the Savage Land (Marvel's jungle hidden in the Antarctic where dinosaurs, cavemen, etc, still exist) to track down the Dinobots. And of course there was Circuit Breaker, whom Marvel snuck into a Secret Wars II appearance BEFORE her Transformers debut, just to cement her ownership as being wholly Marvel's.

* ''Franchise/MortalKombat'' does this a lot too. None of the endings in ''VideoGame/MortalKombatVsDCUniverse'' make sense when applied to their respective worlds, and it has been confirmed as non-canon by WordOfGod. The same can be said of the {{Guest Fighter}}s who appear in the later games ([[VideoGame/GodOfWar Kratos]], and [[Franchise/ANightmareOnElmStreet Freddy Krueger]] in ''VideoGame/MortalKombat9'' and [[Franchise/FridayThe13th Jason Voorhees]], Franchise/{{Predator}}, [[Film/TheTexasChainsawMassacre Leatherface]], and the Franchise/{{Alien}} in ''VideoGame/MortalKombatX''; the explanations as to why these guys are Kombatants make little sense when their own canon histories are applied.
** An amusing example of playing with this came from ''VideoGame/Injustice2'', featuring Sub-Zero and Raiden as {{Guest Fighter}}s, in that while their official canonicity is pretty much out of the window, [[ImmediateSequel their arcade storylines pick off directly after the events of]] ''VideoGame/MortalKombatX'', and some of their dialogues reference past events from ''VideoGame/MortalKombatVsDCUniverse'', including fighting [[BigBad Dark Kahn]].

#'''Story issues'''. In other cases, the crossing universes are just so different that having the crossover be canon just doesn't make any sense for one or both of the properties. Maybe the usual tones are different, such as one being a plot-heavy {{Dramedy}} and the other a WidgetSeries with a loose grip on continuity?[[note]]Such is the case with the page quote, with ''WesternAnimation/StevenUniverse'' being the former and ''WesternAnimation/UncleGrandpa'' the latter.[[/note]] Maybe the writers feel like acknowledging the crossover would mess with whatever MythArc is going on in one of the properties? Or maybe the crossover was really just because RuleOfFun, and how it would make sense was the farthest thing from anyone's mind. Or maybe all three.

* Similar to USA Network above, [=MeTV=] commercials often feature characters from shows that air on the channel interacting with each other in silly ways, such as [[Series/TheCarolBurnettShow Carol Burnett]] being prosecuted in court by Franchise/PerryMason, [[Series/MacGyver1985 MacGyver]] setting out to rescue [[Series/ILoveLucy Lucy]], [[Series/StarTrekTheOriginalSeries Kirk and Spock]] ending up in [[Series/TheAndyGriffithShow Mayberry]] after jumping through [[Recap/StarTrekS1E28TheCityOnTheEdgeOfForever The Guardian of Forever]][[note]]Helped by New York City in that ''Trek'' episode using the same set as ''Andy Griffith''[[/note]], and [[Series/MamasFamily Mama]] showing up pretty much anywhere in any show's universe.

* A VideoGame and DigitalPinballTable example: In addition to the [[VideoGame/SonicTheHedgehog titular hedgehog]], ''VideoGame/SonicPinballParty'' also features [[VideoGame/NightsIntoDreams NiGHTS]] and ''VideoGame/SambaDeAmigo'', but the three characters never actually interact with each other.

* Normally, one would expect ''VideoGame/NamcoXCapcom'', which uses a shared world concept, and it's followups the ''VideoGame/EndlessFrontier'' and ''VideoGame/ProjectXZone'' games would fall into this easily. And for most of the series' involved they do. Until ''VideoGame/SuperRobotWarsOriginalGeneration: The Moon Dwellers'' brought ''Endless Frontier's'' Haken Browning to the OG series, mentioning his meeting with Sanger Zonvolt in the first ''Project X Zone''. This makes [=NxC=]/PXZ's shared world an explicit part of the VideoGame/SuperRobotWars multiverse.

* FanArt and {{Fan Fic}}s in general are very prone to this like those on Website/DeviantArt from the United States and Website/{{Pixiv}} from Japan. The only exception is ''FanFic/Hottie3TheBestFanFicInTheWorld'', which tries to avoid as much CanonDiscontinuity as possible.

* There was, actually, a crossover between [[Comicbook/DisneyMouseAndDuckComics Donald Duck]] and Comicbook/{{Tintin}}, entitled ''[[https://coa.inducks.org/story.php?c=I+TL+2501-6 Freedom of Art]]'' (it hasn't been printed in the U.S. yet, and might [[NoExportForYou never be]]). However, the current owners of the copyright to Hergé's characters threatened to sue Disney, leading them to slightly tweak the characters' names (Tintin became Denden, Haddock became “Hadciuk”…) and market it as a mere tribute.

* ''ComicBook/MercuryHeat'' once did a "crossover" with ''ComicBook/{{Crossed}}''. However, it was non-canon for the latter due to the fact that ''Crossed'' is established as a work of fiction within the universe of ''Mercury Heat'', and the HatePlague outbreak was caused by a mad genetic engineer who was a fan of it.

* Creator/KidsWB's promos had [[https://www.youtube.com/watch?v=ntqFDch_Iuo moments]] like [[Anime/{{Pokemon}} Team Rocket]] sneaking into Anime/YuGiOh's Duelist Kingdom, or the entire network's casts going on road trips and doing stunts together.

* ''Fanfic/FireEmblemThreeHousesFifthPath'' features an Omake that serves as a fan crossover with Zelda Universe’s WebAnimation/HadesMisguidance that is explicitly stated to not be canon to the fic’s universe.

[[folder: Fan Works]]

* One episode of ''Webanimation/RWBYChibi'' had Ruby dreaming of encountering [[Webanimation/{{RWBY}} the original version]].

* ''ComicStrip/PearlsBeforeSwine'' frequently features the characters meeting characters from other comic strips, all of which are ''definitely'' non-canon for the other strip. A borderline example is a CrossoverPunchline with ''Webcomic/SallyForthHoward'' during a storyline where Rat is a hotel concierge; the Forths ''were'' on vacation at the time, and the same day's ''Sally'' had Ted say he'd been speaking to the concierge, but in the ''PBS'' strip he asks Rat to find him an escort, which ... ''probably'' didn't happen in ''Sally Forth'' continuity.

*** This has also happened with other crossover toys. The ExcusePlot for the ''[[Creator/MarvelComics Marvel]]'' crossover line was that [[ComicBook/FantasticFour Mr. Fantastic]] gave the heroes vehicles that turned into large versions of themselves... Which doesn't explains why ''Carnage'' has a toy. Other properties haven't gotten better treatment, with there being official ''Transformers'' toys for ''Franchise/HelloKitty'', ''WesternAnimation/MickeyMouse'', ''Franchise/{{Peanuts}}'' having no in-universe explanation on why they have transforming mecha based on them.

* In the same vein, there's a set of ''WesternAnimation/DespicableMe'' ads for Japan set in the ''VideoGame/InazumaEleven'' 'verse as seen [[https://www.youtube.com/watch?v=8IpP41RrN58 here]].

* Creator/CartoonNetwork has a lot of promos featuring odd crossovers. Favorites include several superheroes from different cartoons [[https://www.youtube.com/watch?v=-VXRHw9O754 going to a movie theater]] and an even larger crossover taking place [[https://www.youtube.com/watch?v=VuqItc1rZGg in a cafeteria]], and of course we can't forget the time [[https://youtu.be/_mcy3L6WQDw Ben 10 met the Justice League]].

** In "Super Best Friends", the cast of ''Series/ThatsMyBush'' is shown in the White House. While both shows were created by Trey Parker and Matt Stone, it still counts as fake since ''Series/ThatsMyBush'' is a ''live action show''.

** Back in ''Series/MightyMorphinPowerRangers'', the three-part episode 'A Friend in Need' served as a PoorlyDisguisedPilot for the by-then-in-production ''Series/MaskedRider''. However the first episode of ''Masked Rider'' proper contradicts what happened in 'A Friend in Need' and besides a passing mention in the final arc of ''Mighty Morphin'', both series never acknowledged each other again.
** Early in ''Series/PowerRangersInSpace'', an episode revolved around the '''''Franchise/TeenageMutantNinjaTurtles''''' themselves being brainwashed by the villains to attack the Rangers, specifically the incarnations from ''Series/NinjaTurtlesTheNextMutation''. For obvious reason regarding copyright, no acknowledgement of the Rangers living in the same world as the Turtles has happened ever since, albeit funnily enough over twenty years later there would be another crossover between the two properties in [[ComicBook/MightyMorphinPowerRangersTeenageMutantNinjaTurtles comic form]].
