->''"Don't worry, bro, none of this is canon."''
-->-- '''WesternAnimation/UncleGrandpa''', ''WesternAnimation/StevenUniverse'', "[[Recap/StevenUniverseS2E4SayUncle Say Uncle]]"

A {{Crossover}} which, for some reason or other, clearly doesn't count even remotely within the visiting characters' continuity. The characters might look and act the same, but you know these events are actually never going to be referenced in their own show. This may be due to copyright or because one continuity clashes too much with the other.

* Progressive, an insurance company with plenty of advertisement, had an advertisement cross over with ''Franchise/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.

* Plue is a summon that Lucy uses in ''Manga/FairyTail'' who originated from ''Manga/RaveMaster''.
** Griff showed up on ''the cover'' of Volume 6 of ''Manga/FairyTail''. He also pops up when [[spoiler: Wendy is being welcomed into Fairy Tail]] and in Episode 21 (Happy is ''eating'' him while they're at Lucy's house).
** A character from Plue's Dog Diaries is in the trash can in one of the omake.
** Elie is amidst the crowd fleeing the train station in the Lullaby arc. She even has her weapon out.
** In Yajima's restaurant, there's a man [[Manga/RaveMaster dressed like Ruby who has his same]] [[VerbalTic verbal tic: poyo!]]
** The anime sees the return of the Jiggle Butt Gang (a.k.a., the Big Butt Bandits).
** The beach omake not only has Elie and Julia in it, but ShipTease for Belnika/Musica, which was quickly shoved aside in ''Manga/RaveMaster'' in order to deal with the final battle.
** Aside from characters from Rave Master making cameos in Fairy Tail, several names are used in both series. Etherion, Oración Seis, and the Ten Commandments just to name a few...
* The ''Anime/LupinIIIVsDetectiveConan'' special and movie can't really take place in the same universe as the two series. Not only has Lupin been mentioned as a fictional character in one of the ''Manga/DetectiveConan'' films, but SherlockHolmes was a real-life person in Lupin's series, yet is still a fictional character in Conan's.
* The ''Manga/OnePiece X Manga/{{Toriko}}'' crossover manga and TV specials, the ''Manga/OnePiece'' and ''Franchise/DragonBall'' crossover, Cross Epoch, and the crossover special featuring all three. Interestingly, in the Super Collaboration Special, Luffy and Toriko recognize each other from their past meetings but have no idea who Goku is.

[[folder:Comic Books]]
* Most crossovers between Creator/{{Marvel|Comics}} and Creator/DCComics never get referenced in their own lines. The exception is ''Comicbook/JLAAvengers'', which had lasting influences on DC's universe, though the other company's characters can't be mentioned or depicted in flashbacks.
** 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...")
*** Comicbook/{{Azrael}} references longtime Punisher foe Jigsaw by ''name'' during the Knightsend story arc, indicating that the crossover between Punisher and the Azrael-Batman was either canon for the sake of DC's side of things, or that someone messed up in writing the script for the issue in which it is mentioned.
*** What makes it awesome is that the Batman/Punisher crossover was the second part of a two-part story. The first one? ''ComicBook/ArchieMeetsThePunisher'', which also {{Sequel Hook}}ed it.
** 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
** One story that started in Comicbook/{{Aquaman}} #56 was concluded in Comicbook/SubMariner #72, written by the same author. (Mind you, there was a three year gap between the two issues).
** Are we also assuming that ''Series/GuidingLight'' did ''not'' in fact take place in the Marvel Universe? ...good.
** 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.
** Parallax remembered that Cyborg (the evil Superman clone, not the one from the Teen Titans) once escaped to another universe, and that he had to pursue him. Just that. He does not mention Cyborg's fight with the Silver Surfer or his own fight with Thanos, at the Green Lantern-Silver Surfer crossover.
* There were a few ''ComicBook/XMen'' + ''Series/StarTrekTheNextGeneration'' comic crossovers, which is HilariousInHindsight thanks to Creator/PatrickStewart.
** These were followed by ''Comicbook/StarTrekTheNextGenerationDoctorWhoAssimilation2'', which was automatically made a Fake Crossover for on both sides via canon policies for both series (''Star Trek'' comics are non-canon, period, whereas as a public broadcaster, the BBC's charter forbids its fiction programs to make plot-critical references to merchandise, which much of the ''Franchise/DoctorWhoExpandedUniverse'' would qualify as, though the mini-sode "Night of the Doctor" averts that with the Eighth Doctor on screen name-dropping his expanded universe companions)
* 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.
* Topps' ''Comicbook/JasonVsLeatherface'' crossover, taking place after ''Film/FridayThe13thPartVIJasonLives'', is an AlternateContinuity, as it features characters who are either deceased or have different names in their own stories.
* ''NBC Saturday Morning Comics'' #1 has characters from several shows appearing together on the cover, but they are all self-contained stories.
* The ''Franchise/GIJoe'' comics had two in-continuity crossovers with ''Comicbook/TheTransformers'' comics during the Marvel run (with one of them occurring within the regular ''G.I. Joe'' series). When the comic was later revived by Devil's Due, the events of both crossovers were retconned and major events in the crossovers that affected the ongoing continuity (such as [[spoiler:Dr. Mindbender's revival]]) had to be explained differently.
** 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/TheTransformers'' 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.
** Ironically in the original four issue mini, both Nick Fury and Dum Dum Duggan appear and briefly reference ''Franchise/{{Godzilla}}'s'' [[Comicbook/GodzillaKingOfTheMonsters Marvel run]] when news first starts to spread about living robots coming out of Mt. Saint Helens. It should also be noted that the military vehicles used by the army in that episode were in fact G.I. Joe weapons: The MOBAT Tanks and the Wolverine Missile vehicle.
* "Into the Great Unknown" is a ''Franchise/StarWars'' and ''Franchise/IndianaJones'' crossover where the ''Millenium Falcon'' crash-lands on Indie's homeworld and he finds a [[ActorAllusion very familiar-looking fellow]] inside, dead.

[[folder:Films -- Animation]]
* In ''Disney/WreckItRalph'', video game characters are like electronic LivingToys local to Litwak's Family Fun Center arcade. In theory, more than one of the same arcade cabinet at the same location would produce duplicate characters.

[[folder:Films -- Live-Action]]
* MartialArtsMovie titles may imply a crossover, such as ''Kung Fu Masters: Jackie Chan vs. Bruce Lee'', ''Bruce Lee vs. Jackie Chan'', or ''Jackie Chan vs. Jet Lee''; these are collections of separate movies. Movies like ''Cinema of Vengeance'', ''Top Fighter'' and ''The Deadliest Art'' may claim to be starring all of the main actors featured on the cover, but are actually documentaries full of StockFootage interviews and movie clips.
* An [[http://www.youtube.com/watch?v=8KOghs-hX7g advert for Sky Movies]] cuts together multiple ''Film/JamesBond'' {{car chase}}s to make them appear to be racing/chasing/killing off each other. Since canonically they're all supposed to be ''the same person''...
* In ''Film/{{Pixels}}'', the video game characters are not part of a crossover, as they are aliens appearing as video game characters.
* ''Film/KamenRiderG'' has a scene where [[Series/KamenRiderDecade Decade]] appears and calls in the other Heisei Riders to give G a pep talk. It's also a one-off special [[AffectionateParody Affectionately Parodying]] the entire ''Franchise/KamenRider'' franchise, so odds are it's not canon to any of the shows, especially considering the BigBad of ''G'' shows up in ''Decade'' as the BigBad of the [[Series/KamenRiderKabuto World of Kabuto]] arc with nary a reaction and G himself never appears in any crossover film gathering all Riders.
** Both Series/KamenRiderDenO and Series/KamenRiderFourze have met the cast of ''Manga/CrayonShinChan''; the former has Shinnosuke transforming into Kamen Rider Shin-O with the power of the Three-Assed Pig Imagin, while in the latter he turns into an Astro Switch that lets Fourze undergo a ToonTransformation.
** In regards to ''Kamen Rider'' as a whole, the annual ''Movie Wars'' films tend to fit this trope when it comes to the current show (for the cast of the previous show, it tends to be a [[PostscriptSeason Postscript Movie]] or more rarely a GrandFinale). The Rider will gain some kind of movie-exclusive SuperMode or item that never turns up in the series proper, and [[SupermanStaysOutOfGotham they'll never think to ask the Riders they met before for help]] when things start looking bad later in their own series. In a few cases, the movie completely clashes with the series' continuity or the characters' established personalities (the biggest offender being ''Series/KamenRiderOOO''[='s=] portion of ''Movie Wars Core''). ''Series/KamenRiderFourze'' is a rare exception to this as Fourze does use the Super Mode he gained in ''Movie Wars Megamax'' later on in the series.

[[folder:Live-Action TV]]
* The charity special "[[Recap/DoctorWho30thASDimensionsInTime Dimensions in Time]]" was a ''Series/DoctorWho''/''Series/EastEnders'' crossover. Since the shows have since been shown as MutuallyFictional, it's probably fair to say it never happened. (And before the new ''Doctor Who'' series established it as such, the tie-in novel ''[[Recap/DoctorWhoNewAdventuresFirstFrontier First Frontier]]'' wrote it off as AllJustADream).
* A [[http://www.youtube.com/watch?v=9elNqC8c38k promo]] for the Japanese DVD season sets of ''Series/{{House}}'' featured the title character teaming up with fellow DrJerk Manga/BlackJack.
* One of the sweeter crossover yet not-a-crossover moments occurred on ''Series/ILoveLucy''. George Reeves appeared, wearing his Franchise/{{Superman}} costume, and was referred to exclusively as "Superman" by the rest of the cast. The dialogue was designed to avoid spoiling for the children in the audience the illusion that this was the genuine Superman -- while making it clear to the adults watching the program that Ricky and Lucy were interacting with the actor George Reeves and calling him Superman merely as a playful but respectful reference to his famous character. There's a meta-joke where Reeves moves a piece of heavy furniture -- causally -- with one hand -- and the adults looked momentarily stunned. [[RealAfterAll Maybe it WAS a crossover?]]
* ''Series/{{Monk}}'' and several of the Creator/USANetwork shows including ''Series/TheFortyFourHundred'' and ''Series/{{Psych}}'' were crossed over in a series of their commercials. Since ''Monk'' takes place in San Francisco CA, ''The 4400'' in Seattle WA, and ''Psych'' in Santa Barbara, CA -- it's unlikely the crossover would ever happen canonically to any of the aforementioned shows.
** USA loves doing this:
*** The campaign leading up to the premiere of ''Series/InPlainSight'' had Mary being visited by characters from USA's other shows, who would give her "housewarming" gifts and welcome her to "the neighborhood". Perhaps the funniest involved Wrestling/{{WWE}} wrestler Wrestling/TheBigShow bringing Mary a gift wrapped folding chair, then being denied access to her bathroom.
*** Similarly, in one ad for ''Series/RoyalPains'', [[Series/BurnNotice Michael Westen]] sends Hank Lawson a care package containing sunglasses, sunscreen, and a brick of C4 "because you never know when you'll need a stable plastic explosive."
*** The characters from ''Series/WhiteCollar'' have started appearing in these as well - they have done crossover commercials with ''Psych'', ''Wrestling/WWERaw'' (the Big Show again) and ''Series/BurnNotice''.
*** Also, in celebration of ''Monk'''s final season, USA released a new round of ads where the characters from all of its currently airing original shows (''Series/BurnNotice'', ''Series/{{Psych}}'', ''Series/InPlainSight'', ''Series/RoyalPains'', ''Wrestling/WWERaw'', ''Series/LawAndOrderCriminalIntent'') give their opinions and recount their experiences with the titular detective.
*** In the series finale of ''Psych'', [[spoiler: Shawn goes to San Francisco to be with Juliet and Gus follows. While the Chief is happy to see them, she mentions they already have a consultant who is implied to be Monk (said consultant is said to be "in the kitchen, alphabetizing the cereal boxes"),]] making this more interesting.
** The commercials for ''Film/HellboyIITheGoldenArmy'' did the same thing, with [[FanNickname Big Red]] meeting up with James Lipton, ''Series/{{Chuck}}'', appearing on ''Series/GhostHunters'' and ''Series/AmericanGladiators'' and doing a "The More You Know" PSA.
** In 2009, ABC started a new ad campaign called the "ABC House" in which characters from various ABC shows live together under one roof.
*** One such ad seemed designed to toy with ''Series/{{Lost}}'' fans: Dominic Monaghan, who played Charlie, appears in one of the ads, even though he wasn't on an ABC show at the time. His death is even mentioned in the ad. Fans went wild wondering if the ad confirmed he was coming back to ''Lost''. A few weeks later, he was revealed to be joining the cast of ''Flash Forward'', a new ABC show...[[spoiler:although he did appear throughout the final season]].
* Franchise/TheMuppets are prone to this:
** ''Series/TheCosbyShow'' had an entire episode of a dream sequence, with the second half involving characters from ''Series/TheJimHensonHour''.
** ''Scrubs'' made a guest appearance in ''Film/ItsAVeryMerryMuppetChristmasMovie'', as Miss Piggy's very brief acting career (she plays a patient who dies during an operation).
*** In turn, Oscar the Grouch, Grover and Elmo from ''Series/SesameStreet'' as well as a generic orange Muppet appear in the ''Scrubs'' episode "My ABC's". All within J.D.'s {{Imagine Spot}}s, of course. And in turn, said generic orange Muppet would later make a cameo in a season 40 episode of ''Sesame Street''; the scene in question doesn't mention ''Scrubs'' but it does implicitly alludes to it as its subject was x-rays.
** There was of course ''Series/TheMuppetShow'' episode where [[Franchise/StarWars Luke Skywalker, Chewbacca, C-3PO and R2-D2]] guest starred[[note]]Mind you, this was decades before the two franchises would wind up under [[Creator/{{Disney}} the same umbrella]] by chance[[/note]], alongside Mark Hamill, presented in the show as Luke's "cousin." (This was apparently regarded by Lucasfilm as an "Infinities"-level canon material before the massive reorganization of Star Wars continuity.)
** ''Film/TheMuppetMovie'' featured Big Bird in a cameo in which he is journeying to New York in order to make it in public television, something that would be out of odds with ''Series/SesameStreet''[='=]s treatment of the character.
** Beaker is supposed to be related to Wrestling/{{WWE}} wrestler Wrestling/{{Sheamus}} according to a Monday Night Raw Halloween broadcast.
* One episode of ''Series/{{Roseanne}}'' had Luke and Laura, of ''Series/GeneralHospital'', talking with Dan and Roseanne about the wacky adventures each couple had experienced throughout their respective marriages.
* The Christmas episode of ''Series/FatherTed'' featured the cast of the contemporary Irish comedy ''Series/{{Ballykissangel}}''. However, it was a dream sequence.

* ''Theatre/AvenueQ'' and ''Theatre/FiddlerOnTheRoof'' had a hilarious one of these for the 2008 Easter Bonnet competition in which everyone was Jewish and lived on "Avenue Jew", obviously it didn't affect the plotline of either show.
* Creator/WoodyAllen's play ''God'' has as one of its characters Blanche [=DuBois=], who escaped the two men who were trying to put her into a straitjacket at the end of ''Theatre/AStreetcarNamedDesire'' and wants desperately to get herself into a play where God exists.

* ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]'' crossovers, including ''Series/StarTrekTheOriginalSeries'', ''[[Franchise/UniversalHorror Universal Monsters]]'', and Troll dolls, were typically the source material characters amalgamated with the four main turtles.
* ''Franchise/{{Transformers}}''
** The ''Literature/{{Animorphs}}'' crossover has characters turning into animals like in the source material, but it does not actually involve ''Franchise/{{Transformers}}''.
** The ''G.I. Joe and the Transformers'' San Diego Comic-Con exclusives feature characters from both series. The sets are mostly commemorative instead of presenting a new story to justify the crossover.
** The crossover with ''Franchise/StarWars'' features ships that turn into giant versions of ''Franchise/StarWars'' characters, fitting into continuity ''with your imagination''.

[[folder:Video Games]]
* As a general rule, any game that has a CharacterCustomization feature can allow for this. Special mention goes to the ''VideoGame/{{Mii}}'' series of games that, thanks to the simplistic yet surprisingly flexible system, and ease of sharing Miis to others systems, has a near ''uncountable'' amount of [=Miis=] based on characters from ''many, many'' franchises.
* In ''VideoGame/AngryBirdsTransformers'', the Eggspark turns the birds and pigs into the Autobirds and Deceptihogs, so the ''VideoGame/AngryBirds'' characters are only playing as the ''Franchise/{{Transformers}}'' characters.
* ''VideoGame/TheBattleCats'' crossovers usually feature characters based on the source material instead of the actual characters.
* ''VideoGame/PlaystationMoveHeroes'' makes no sense when it comes to the ''Franchise/SlyCooper'' timeline. The most logical conclusion is that it takes place between the second and third games, since Bentley is using his hoverchair and Sly hasn't retired from heisting, but in the opening cutscene, they are trying to break Murray, who is supposed to be on a worldwide journey of enlightenment, out of prison.
* ''VideoGame/ProfessorLaytonVsPhoenixWrightAceAttorney'''s special episodes couldn't possibly exist within the Ace Attorney timeline. Besides the fact that those episodes gleefully break the fourth wall, Maya uses Luke Atmey's Borrowed Catchphrase "Zvarri!" and Phoenix still clearly has his badge, so it can be concluded that the main events of the game must take place between Case 3-2 on October 11-14, 2018 and Phoenix's disbarment on April 19, 2019. While this gives ample time for the events in Labrynthia to take place, it's explicitly mentioned that the special episodes take place a year afterwards, putting them in late 2019 or early 2020. By this point, Phoenix is disbarred and Maya is off serving as the Master of the Fey clan, so there is no logical reason for the Ace Attorney characters to be in London at all.
* A VideoGame and DigitalPinballTable example: In addition to the [[Franchise/SonicTheHedgehog titular hedgehog]], ''VideoGame/SonicPinballParty'' also features [[VideoGames/NightsIntoDreams NiGHTS]] and ''VideoGame/SambaDeAmigo'', but the three characters never actually interact with each other.
* Do you really think ''[[VideoGame/SoulSeries Soul Edge]]'' or ''[[VideoGame/SoulSeries Soul Calibur]]'' will ever show up in the ''Franchise/StarWars'', ''Franchise/TheLegendOfZelda'', ''VideoGame/{{God of War|Series}}'' or Creator/{{Image|Comics}}[[note]]through ComicBook/{{Spawn}}'s involvement[[/note]] universes?
** While the ''Soul'' series ''does'' share continuity with ''VideoGame/{{Tekken}}'' (Soul's Yoshimitsu is the ancestor of Tekken's Yoshimitsu), Heihachi's appearance in ''Soul Calibur II'' was '''not''' canon.
** Actually, there is a ''Soul Calibur'' crossover under the ''Star Wars'' label: ''Visions of the Blade'' and both titular weapons made appearances. However, it was published under the Infinities label and is non-canon.
* 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 ''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 (Who most certainly did ''not'' join Mario, Yoshi, and the Kong family for a [[VideoGame/DonkeyKongCountry coin collecting competition]]) is canon, because ''everything'' in the ''Mario'' franchise [[NegativeContinuity is canon]].
* ''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/GodOfWarSeries Kratos]], and [[Franchise/ANightmareOnElmStreet Freddy Krueger]] in ''VideoGame/MortalKombat9'' and [[Franchise/FridayThe13th Jason Voorhees]], Franchise/{{Predator}}, [[Franchise/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.
* The events of "Mesal Gear Solid: Snake Escape" and "Snake vs. Monkey" are unlikely to be referenced in any future ''Franchise/MetalGear'' or ''VideoGame/ApeEscape'' game.
* Basically any game in Creator/{{Capcom}}'s ''[[VideoGame/CapcomVsWhatever Vs series]]'' (i.e: ''VideoGame/MarvelVsCapcom'', ''VideoGame/SNKVsCapcom'', ''VideoGame/TatsunokoVsCapcom''). Actually, the ''Marvel vs. Capcom'' games (and [[{{VideoGame/XMenChildrenOfTheAtom}} their]] [[{{VideoGame/MarvelSuperHeroes}} predecessors]]) take place in an official Marvel [[AlternateUniverse universe]] named "[[http://marvel.wikia.com/Earth-30847 Earth-30847]]", completely separate from [[http://marvel.wikia.com/Earth-616 Earth-616]] (AKA the main Marvel universe), so they're not technically Fake Crossovers on the Marvel side.
* A [[http://www.youtube.com/watch?v=Skf1oDUgrw8 promo]] of ''VideoGame/DanballSenki'' features the main characters arriving at the club room of [[VideoGame/InazumaEleven Raimon football club]].
* 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.
** Similarly, the previous game also treated the appearances of three of it's characters in ''VideoGame/AnotherCenturysEpisode R'' as an actual disappearance that gets resolved in that game.
* While [[VideoGame/HotlineMiami Jacket]] as a ''character'' in ''VideoGame/Payday2'' is canon, the differing time-frames and KillEmAll ending of the second game makes the events of his home series incompatible with that of ''Payday''. This is in contrast to the rest of the guest characters, whose movies are implied to have "already happened" (or will happen in the case of [[Film/HardcoreHenry Jimmy]]).
* In ''Virtua Quest'', the characters of ''VideoGame/VirtuaFighter'' exist as data in the Nexus, a virtual world.
* VideoGame/TokyoMirageSessionsFE was marketed as a {{Crossover}} between Franchise/ShinMegamiTensei and Franchise/FireEmblem, but the closest the game comes to having SMT character in it is by having [[SeriesMascot Jack Frost]] as the mascot of a store and a [[EvilCounterpart Black Frost]] mask. The FE cast are all mirages who [[YouDontLookLikeYou hardly look like themselves]] and are essentially [[Franchise/ShinMegamiTenseiPersona Personas]] who talk more than usual. The rest of the cast (which is what most of the plot that doesn't revolve around [[EndOfTheWorldSpecial saving the world]] is about) is composed of OriginalGeneration characters. At best, it's a [[Franchise/ShinMegamiTenseiPersona Persona Game]] that plays it's mechanics to mimic the style of Franchise/FireEmblem with [[FightingSpirit Personas]] and [[TheHeartless Shadows]] that ([[YouDontLookLikeYou sort of]]) look and act like Franchise/FireEmblem characters.

[[folder:Web Original]]
* 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.
* The crossover between ''WebVideo/TheAngryVideoGameNerd'' and ''WebVideo/TheNewAdventuresOfCaptainS'' in which Cap and the Nerd team up to save [[SavingChristmas rescue Santa Claus]] was explicitly non-canon within Cap's continuity. Just as well, as the Nerd was totally neutered - he was only allowed to swear once (which was bleeped).
** This seems to be canon in [[WebVideo/TheAngryVideoGameNerd Nerd]] videos. [[NegativeContinuity What canon there is, anyway...]]
* "Beans", a three-part crossover between the three most popular ''VideoGame/SuperSmashBros Melée/Brawl'' machinimas on Website/YouTube.
* In the intermission of an episode of ''Podcast/BlackJackJustice'', [[Podcast/RedPandaAdventures the Red Panda]] and the Flying Squirrel show up to deliver a contractually-obligated anniversary wish... and Jack and Trixie get annoyed at them "horning in on our racket". This results in a CatFight between the Squirrel and Trixie, and the men getting very distracted by it. At the end:
-->'''The Red Panda:''' So, does this count as a crossover?\\
'''Jack Justice:''' Don't push it.

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'' has done this innumerable times, such as:
** Harry Morgan appeared as [[Franchise/{{Dragnet}} Bill Gannon]].
** David Duchovny and Gillian Anderson appeared as [[Series/TheXFiles Mulder and Scully]].
** Patrick [=McGoohan=] appeared as Number 6 from ''Series/ThePrisoner''.
** In "Mathlete's Feat", [[WesternAnimation/RickAndMorty Rick and Morty]] crash land into the couch gag, smooshing the Simpsons family. Morty travels to the future of ''WesternAnimation/{{Futurama}}'' in an attempt to undo the damage.
* ''WesternAnimation/SouthPark''
** A more blatant example would be when WesternAnimation/DrKatzProfessionalTherapist appeared in "Summer Sucks" and was incinerated by lava.
** 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''.
* On ''WesternAnimation/TheVentureBrothers'', Race Bannon from ''WesternAnimation/JonnyQuest'' makes an appearance in "Ice Station-- Impossible!", but dies onscreen. In the season 2 episode "Twenty Years to Midnight", the group has an encounter with a deranged, drug-addled, middle-aged Jonny Quest.
** In the third season you see Hadji working a desk job for Dr. Venture, Race in a flash-back torturing a [[Franchise/GIJoe SPHINX]] operative, Jonny working at a day camp hosted on the Venture compound, and Dr. Zin visits him.
*** The "fakeness" of these crossovers is debatable. Cartoon Network Studios -- originally Creator/HannaBarbera -- has the official rights to the Jonny Quest characters, and they were referred to by name, until...
*** From season three onward, the creators have walked this back a bit, referring to Johnny only by his first name and Dr. Zin only as "Doctor Z". This is due to an planned LiveActionAdaptation of ''Jonny Quest'' currently in DevelopmentHell, which forced the writers to be more subtle about who the characters really are by turning them into [[CaptainErsatz pastiches]] of the Quest cast.
* ''WesternAnimation/FamilyGuy''
** A DeletedScene in the episode "Movin' Out (Brian's Song)" involves Quagmire visiting ''WesternAnimation/TheSimpsons''. This one is not an official crossover like ''[[Recap/FamilyGuyS13E1TheSimpsonsGuy The Simpsons Guy]]''.
** As well as the ''WesternAnimation/AmericanDad'' characters in "Lois Kills Stewie", which was [[AllJustADream all just a simulation]].
** Roger's cameo at the end of the time-traveling season 5 finale.
** The season 8 episode "The Splendid Source" has Peter and his friends trying to track down the origin of a dirty joke with Bender from ''Futurama'' being one in a chain of many others that have heard the joke.
** Coach [=McGuirk=] from ''WesternAnimation/HomeMovies'' appears at Mos Eisley cantina in "Blue Harvest."
* Creator/GregWeisman (creator of ''WesternAnimation/{{Gargoyles}}'', ''WesternAnimation/TheSpectacularSpiderMan'' and ''WesternAnimation/YoungJustice'') staged several radio plays for cons that were crossovers between his three shows. Naturally, it falls under this trope.
* [[WesternAnimation/FamilyGuy Stewie Griffin]] on ''Series/{{Bones}}'', via a [[spoiler: brain tumour induced]] hallucination.
* A series of promotional shorts for ''[[Creator/DiscoveryFamily The Hub]]'' had [[WesternAnimation/MyLittlePonyFriendshipIsMagic Pinkie Pie]] messing with Dan from ''WesternAnimation/DanVs'' Other shorts included the [[WesternAnimation/TransformersPrime Transformers]], WesternAnimation/StrawberryShortcake, the [[WesternAnimation/PoundPuppies2010 Pound Puppies]], and even [[WesternAnimation/BatmanTheAnimatedSeries Batman]].
* Did someone say promo? How about Franchise/{{Nicktoons}}' [[https://www.youtube.com/watch?v=Y69U-9JWDz4 Summer Beach House]] from 2002? ''WesternAnimation/{{Rugrats}}'', ''WesternAnimation/HeyArnold'', ''WesternAnimation/{{SpongeBob|SquarePants}}'', ''WesternAnimation/RocketPower'', ''WesternAnimation/TheWildThornberrys'', and ''[[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]]''.
* 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]].
* In the same vein, there are a set of ''WesternAnimation/DespicableMe'' ads for Japan set in the ''VideoGame/InazumaEleven'' 'verse as seen [[http://www.youtube.com/watch?v=8IpP41RrN58 here]].
* [[WesternAnimation/TheFairlyOddParents Cosmo and Wanda]] appear in an episode of ''Series/NedsDeclassifiedSchoolSurvivalGuide''. (Specifically, one of [[MrImagination Ned's]] {{Imagine Spot}}s)
* The fourth season premier of ''WesternAnimation/{{Archer}}'' opens with what seems to be the eponymous restaurant of ''WesternAnimation/BobsBurgers'' with the Belcher family inside, Bob (who happens to have the same voice actor as Archer) included. [[spoiler:It turns out "Bob" ''was'' Archer, who was suffering from IdentityAmnesia for a few months. Apparently there is no real Bob here and Linda's kids were from another marriage.]]
* ''[[WesternAnimation/TheGrimAdventuresOfBillyAndMandy The Grim Adventures of the]] [[WesternAnimation/CodenameKidsNextDoor Kids Next Door.]]'' Oddly enough, it was given a place in the continuity heavy ''Kids Next Door'' by its creator Tom Warburton, [[http://warburtonlabs.blogspot.co.uk/2010/03/grim-adventures-of-knd.html who placed the events of the special sometime after Operation: ZERO]]. In contrast, when asked about the canon status of this and the CN Invaded special for ''Billy & Mandy'', Maxwell Atoms pointed out his show's [[NegativeContinuity far more casual relationship with continuity by]] [[http://maxwellatoms.tumblr.com/post/127192112752/was-cn-invadeds-entire-story-w-the-other-cn jokingly stating]] "The only parts that are truly canon are the ones where a main character dies, is banished to another dimension forever, is erased from existence, or is turned into chocolate and devours himself."
* ''WesternAnimation/InspectorGadget'' appeared in one episode of ''WesternAnimation/StuntDawgs''. It was a cameo and Sizzle told him he was in the wrong cartoon.
* ''WesternAnimation/PhineasAndFerb'':
** The opening crawl for ''WesternAnimation/PhineasAndFerbStarWars'' flat out states that the special isn't canon for both franchises, so the audience should just relax and enjoy it.
** Whether their crossover with the Marvel universe is canon or not is also debatable, and it's never referenced again in later episodes (though, a zany cartoon like ''Phineas and Ferb'' has only a loose sense of continuity at best, anyway).
* An older Sally and Doowee from ''WesternAnimation/SallyBollywood'' appear in an episode of ''WesternAnimation/BaskupTonyParker'', but in that universe they're actors and ''Sally Bollywood'' was just a TV show.
* Ickis, Krumm and Oblina from ''WesternAnimation/AaahhRealMonsters'' appeared in a ''WesternAnimation/{{Rugrats}}'' Halloween special as part of a dream sequence.
* The ''WesternAnimation/StevenUniverse'' episode "Say Uncle" has the show crossover with, of all series, ''WesternAnimation/UncleGrandpa''. The page quote is from that very episode, with Uncle Grandpa assuring both Steven ''and'' the audience that [[MediumAwareness "None of this is canon."]]
** And it's indicated by the end of the episode that [[MassiveMultiplayerCrossover Uncle Grandpa has visited several other Cartoon Network series before Steven]], and WesternAnimation/{{Clarence}} is next. [[UnexpectedCharacter And also on the list?]] The ''WesternAnimation/SwatKats'' (who weren't even made for Cartoon Network, and were made by Creator/HannaBarbera for Creator/{{TBS}})!
* ''WesternAnimation/Ben10Omniverse'' and ''WesternAnimation/TheSecretSaturdays'' had a crossover episode called "T.G.I.S."(Thank Goodness It's Saturday)", where they joined forces to stop Dr. Amino and a resurrected V.V. Argost from raising an army of chupacabras. This episode was made years after ''Secret Saturdays'' ended and had no involvement from any of that show's production (only voice actor returned), making the events of this episode dubious canoncity for that series.
* ''WesternAnimation/TheFlintstones'' had an episode in which Samantha and Darrin Stephens of ''Series/{{Bewitched}}'' fame move to Bedrock. Their relocation from a 1960s suburb to a stone age town never received another reference in either show, as ''Bewitched'' still showed the couple living in the '60s afterward.
* ''WesternAnimation/CartoonAllStarsToTheRescue'': A MassiveMultiplayerCrossover wherein dozens of cartoon characters from various sources were brought together to make an anti-drug PSA. Obviously, this was completely separate from the canons of any of the source characters, as the various characters were seen coming alive from merchandise owned by the main character.
* Mulder and Scully from ''Series/TheXFiles'' appear at the end of the ''WesternAnimation/EekTheCat'' episode "Eek Space 9", even being voiced by David Duchovny and Gillian Anderson. After a spaceship crashes into her office, Scully drops her skepticism of the existence of aliens, something that wouldn't happen on their own show for several years.
