History Main / SharedUniverse

* The final episode of ''WesternAnimation/CampLazlo'' implies that the show takes place in the same universe as ''WesternAnimation/RockosModernLife'' with the appearance of a character who is clearly meant to be an older version of Heifer.

* Several, possibly all, of the different franchises created by Creator/ElephantGames are confirmed to take place in the same universe. This is most evidently confirmed by the CrisisCrossover series ''VideoGame/DetectivesUnited'', but there are also instances of games in one series referencing the events or characters of another, such as Alice Gray (in the ''Grim Tales'' series) calling James Blackthorne (from the ''Haunted Hotel'' games) "Uncle James."

* Through CanonWelding, and Akuma's GuestFighter status, it's suggested that ''Franchise/{{Tekken}}'' and ''Franchise/StreetFighter'' are set in the same universe (or, at the very least, a version of ''Street Fighter'' exists in the ''Tekken'' universe). Likewise, with Geese Howard making an appearance as DLC, ''VideoGame/FatalFury'' and ''VideoGame/TheKingOfFighters'' can be lumped in there as well.

When two works are considered to share a universe by the fandom, see FanonWelding.

** ''Franchise/SuperSentai'' also is a shared universe with frequent crossovers. It also shares a universe with several other {{Tokusatsu}} shows including ''Franchise/KamenRider'' (though this can create a snarl since not all ''Kamen Rider'' shows share a universe as previously stated) and ''Series/MetalHeroes''. An exception is ''Series/UchuSentaiKyuranger'', which takes place in its own universe, since in that show Earth has already been taken over by the villains with no other heroes to stop them, although it is considered part of the same continuity, and so the Kyurangers have been part of a few crossovers where they entered the main universe. Another exception is the noncanonical parody ''Series/HikoninSentaiAkibaranger'' which takes place in a universe where the other Super Sentai series are [[ShowWithinAShow shows within the show.]] Although Akibaranger has been referenced a few times in the main universe, it has not had any true crossovers and is unlikely to. Strangely however, the 45th anniversary series ''Series/KikaiSentaiZenkaiger'' depicts all the previous series as each being in a separate universe, even though this contradicts what was established in the 35th anniversary series. This likely means that each Sentai show has its own universe, but Gokaiger and other crossovers take place in a universe with its own versions of most of the other teams.

* Rick Riordan's various mythology series ''Literature/TheCampHalfBloodSeries'' (actually [[Literature/PercyJacksonAndTheOlympians three]] [[Literature/TheHeroesOfOlympus different]] [[Literature/TheTrialsOfApollo series]]), ''Literature/TheKaneChronicles'', and ''Literature/MagnusChaseAndTheGodsOfAsgard'' all take place within the same universe, the Franchise/{{Riordanverse}}. ''Literature/TheKaneChronicles'' contains several hints towards this end, culminating in [[Literature/DemigodsAndMagicians a crossover]]. [[Literature/MagnusChaseAndTheGodsOfAsgard Magnus Chase]] is actually [[Literature/TheCampHalfBloodSeries Annabeth Chase's]] cousin. This usually doesn't affect the series much, as by-and-large the various gods and mythologies avoid interaction in a sort of deliberate MutualMasquerade, but later books tend more and more towards inter-connectivity, with characters from one series showing up in another.

* The ''WesternAnimation/DCUniverseAnimatedOriginalMovies'' were originally conceived as standalone films, with the occasional sequel or two-parter. Starting with ''WesternAnimation/JusticeLeagueTheFlashpointParadox'', the WesternAnimation/DCAnimatedMovieUniverse was made, first focusing on ComicBook/New52 or ''ComicBook/GrantMorrisonsBatman''-based stories.

* In terms of ''Webcomic/MSPaintAdventures'' comics, ''Webcomic/{{Jailbreak}}'' and ''Webcomic/BardQuest'' take place in the Realm of Imagination of ''Webcomic/ProblemSleuth''. ''Webcomic/{{Homestuck}}'' is the only adventure to not take place in the same world as the previous ones, though ''Problem Sleuth'' exists in-universe as a ShowWithinAShow that the human cast references plenty of times. [[spoiler:''Webcomic/Homestuck2'', on the other hand, brings some of the characters back through the use of a Fenestrated Wall.]]

* Thanks to a single throwaway line, we know that the ''Literature/ChroniclesOfNarnia'' take place in the same universe as the Literature/SherlockHolmes stories. In ''The Last Magician,'' which is chronologically the first story in the series, the narrator mentions that the events of the book were happening at the same time that Mr. Sherlock Holmes was still taking cases in Baker Street.

[[folder:Web Comics]]

* The ''Literature/WhateleyUniverse.'' Right now, there are about a dozen authors writing about twice that many main characters. And that doesn't count the FanFic.

* Initially, ''Literature/TheNeverMythos'' and ''Literature/TheKindnessOfDevils'' were two separate franchises that had no relation to one another short of a ShoutOut here and there. Eventually, the authors decided to combine both franchises into ''Literature/TheNeverkindSaga'', and various crossovers involving characters from both series' happen quite often.

** Phase 1: Focusing on introductory and world-building films like ''Film/IronMan1'', ''Film/TheIncredibleHulk'', ''Film/IronMan2'', ''Film/{{Thor}}'', and ''Film/CaptainAmericaTheFirstAvenger'', with the whole thing coming together in CrisisCrossover ''Film/TheAvengers2012''.
** Phase 2: A running story centering on the gradual panic over potential alien invaders and the appearance of the Infinity Stones drives ''Film/IronMan3'', ''Film/ThorTheDarkWorld'', ''Film/CaptainAmericaTheWinterSoldier'' and ''Film/GuardiansOfTheGalaxy''. This culminates in ''Film/AvengersAgeOfUltron'', where super-science gone wrong nearly destroys the Earth and Thor realizes that someone ''wants'' the Infinity Stones found and united. ''Film/AntMan1'' is a DenouementEpisode that's mostly there to introduce a new hero to the sandbox. In this phase they also began to introduce several TV series set in the MCU, like ''Series/AgentsOfSHIELD'' and ''Series/Daredevil2015''.

* A few Nickelodeon sitcoms happen to share the same universe and some of which are from Creator/DanSchneider. Nicknamed the ''Schneider-verse'', it consists of ''Series/TheAdventuresOfPeteAndPete'', ''Series/TheSecretWorldOfAlexMack'', ''WesternAnimation/SpongebobSquarepants'', ''Series/DrakeAndJosh'', ''Series/{{Unfabulous}}'', ''Series/NedsDeclassifiedSchoolSurvivalGuide'', ''Series/{{Zoey101}}'', ''Series/{{iCarly}}'', ''Series/{{Victorious}}'', ''Series/SamAndCat'' and ''Series/{{iCarly2021}}''.
** The universe may also include other shows that aren't Nickelodeon such as ''Series/FraggleRock'', ''Series/PairOfKings'', ''WesternAnimation/{{WITCH}}'', ''Series/BlackHoleHigh'', ''Series/Flight29Down'', ''Series/ScoutsSafari'', ''Series/DarcysWildLife'', ''WesternAnimation/{{Detentionaire}}'', ''WesternAnimation/DanVs'', ''WesternAnimation/TransformersPrime'', ''Series/RLStinesTheHauntingHourTheSeries'', ''WesternAnimation/GreenLanternThe AnimatedSeries'' and the recent two revival seasons of ''Series/AreYouAfraidOfTheDark''.
** At first it seemed like ''Series/HenryDanger'' and ''Series/GameShakers'' were a part of this universe until the latter had an episode where the characters marathon ''iCarly'' and bet with each other who Freddie loved - Sam or Carly - with Nathan Kress appearing as himself.
** Potential movies that supposedly take place in the ''Schneider-verse'' along with all the numerous shows are ''WesternAnimation/TheIncredibles'', ''Film/ReservoirDogs'', ''Film/TrueRomance'', ''Film/PulpFiction'', ''Film/TheAdventuresOfSharkboyAndLavagirl'', ''Film/TrickrTreat'', ''Film/TheSpiderwickChronicles'', ''Film/{{Krampus}}'', ''Film/DemonKnight'', ''Film/InglouriousBasterds'', ''Film/LightsOut'', ''Film/{{SHAZAM}}'', ''Film/JurassicPark'', ''Film/TheLost WorldJurassicPark'' and ''Film/JurassicParkIII''.

* Interestingly, ''Dino Crisis'' has several crates featuring the [[Franchise/ResidentEvil Umbrella Corporation logo]]. Further, [[LightGunGame Light gun shooter]] GaidenGame ''Dino Stalker'' is actually the third installment of ''Resident Evil'''s spin-off series ''Gun Survivor'', featuring Umbrella {{Easter Egg}}s in the form of the "Woman Drawing Water" statue seen in [[VideoGame/ResidentEvil1 the Spencer Mansion's exhibition room]] and an abandoned Umbrella building.
** Furthermore, the dog that you can rescue from a bear trap early on in ''VideoGame/ResidentEvil4'' is none other than Hewie from sister SurvivalHorror game ''VideoGame/HauntingGround''.

* The Creator/TomClancy series games (''VideoGame/SplinterCell'', ''VideoGame/GhostRecon'', and ''{{VideoGame/HAWX}}'') share a single universe, and often have crossover cameos with each other.

* Although it's a crossover game, ''VideoGame/NamcoXCapcom'' is a special case. The game itself has a world with the settings and characters of several contemporary [[Creator/BandaiNamcoEntertainment Namco]] (''VideoGame/{{Tekken}}'', ''VideoGame/WonderMomo'', ''Franchise/DotHack'', etc.), Creator/{{Capcom}} (''Franchise/StreetFighter'', ''Franchise/ResidentEvil'', ''VideoGame/DeadRising'', etc.), and as ''VideoGame/ProjectXZone'' shows up, even Creator/{{Sega}} (''VideoGame/FightingVipers'', ''VideoGame/DynamiteCop'', etc.) properties co-existing, and implies that ''VideoGame/{{Xenosaga}}'' is its future. Crossover shenanigans involve other universes, then the main characters from the game (and ''Xenosaga'') appeared in the ''VideoGame/EndlessFrontier'' games, which is a side realm of the ''VideoGame/SuperRobotWarsOriginalGeneration'' universe. This came back when characters from the ''Frontier'' and ''OG'' universes appeared in ''Project X Zone'', then went back to ''Super Robot Wars OG: The Moon Dwellers'' discussing their appearance in the previous game.

* Through CanonWelding, and Akuma's GuestFighter status, it's suggested that ''VideoGame/{{Tekken}}'' and ''Franchise/StreetFighter'' are set in the same universe (or, at the very least, a version of ''Street Fighter'' exists in the ''Tekken'' universe). Likewise, with Geese Howard making an appearance as DLC, ''VideoGame/FatalFury'' and ''VideoGame/TheKingOfFighters'' can be lumped in there as well.

** Several of SNK's properties are set in the same universe, if ''VideoGame/TheKingOfFighters'' [[MassiveMultiplayerCrossover is any indication]]. ''The King of Fighters XIV'' backtracks slightly with its Another World Team (consisting of ''VideoGame/SamuraiShodown''[='s=] Nakoruru accompanied by Mui Mui and Love Heart, respectively from the pachinko games ''Dragon Gal'' and ''Sky Love'', all drawn into the ''KOF'' world because of a rift between dimensions), suggesting that the various SNK titles that may or may not fit neatly into the ''KOF'' continuity exist as part of a greater [[TheMultiverse multiverse]].

* ''Film/DangerDiva'' is implied to be set in the same universe as ''Film/ShredderOrpheus'', down to the Grey Zone being a place for the poor, ''Shredder'' actors being cast in similar roles, and high-concept mythological themes.

** Similarly, ''WesternAnimation/HerculesTheAnimatedSeries'' features a crossover where WesternAnimation/{{Hercules}} and WesternAnimation/{{Aladdin}} meet.

** Virtually all of the early Creator/ImageComics titles were set in the same universe, with the stars of any given book often making guest appearances in another or ahving their origins tied to characters from other series. ComicBook/{{Spawn}}'s killer, for example, is Chapel from ''ComicBook/YoungBlood''. However, one of the core ideas of the company was and always has been creator ownership. This caused a ContinuitySnarl no less than ''twice''; Once, when Creator/RobLiefeld picked up his characters and left to create Awesome Comics, necessitating that Spawn's killer be retconned to be Jessica Priest, and again when Jim Lee took ''his'' properties and made his Wildstorm Studios into a DC imprint, which required an entire crossover, ''Shattered Image'', to excise the Creator/WildStorm characters from continuity.

* Various universes of Creator/MarvelComics.
** The Franchise/MarvelUniverse of Earth-616.
** The ComicBook/UltimateMarvel universe.
** ComicBook/Marvel2099

** The Franchise/MarvelUniverse of Earth-616.
** The ComicBook/UltimateMarvel universe.
** ComicBook/Marvel2099
* Similar to Marvel, Franchise/TheDCU is an example of this, with multiple monthly titles who might not even have the same creative team month to month.
** And those two are connected by the Amalgam universe, several canonical crossovers and a few characters who break the fourth wall.
* ''ComicBook/NinjaHighSchool'' and ''ComicBook/GoldDigger'' loosely share a universe and occasionally engage in crossovers or use each other's villains.

* In the ComicBook/SavageDragon, there is a shared universe that not only consists of the rest of the Image Universe but also creator-owned properties such as ComicBook/{{Hellboy}}, Comicbook/{{Madman}}, and ComicBook/{{Bone}} have made appearances. Aside from that, Erik Larsen likes to [[LawyerFriendlyCameo slip in characters from the Marvel Universe and DC Universe]]. Often, this consists of characters showing up far in the background, being mention in passing but not shown, or having a single boot or glove visible that indicates that those characters are there but enough is concealed to avoid copyright issues.
** Virtually all of the early Creator/ImageComics titles were set in the same universe, with the stars of any given book often making guest appearances in another. However, one of the core ideas of the company was and always has been creator ownership. This caused a ContinuitySnarl no less than ''twice''; Once, when Creator/RobLiefeld picked up his characters and left to create Awesome Comics (though he returned after Awesome folded), and again when Jim Lee took ''his'' properties, which encompassed about half a dozen titles, and made his Wildstorm Studios into a DC imprint.
** ''ComicBook/{{Youngblood}}'' has ties to virtually every major Image title in some form or another. Chapel is the man who iced Al Simmons and sent him on the road to becoming Comicbook/{{Spawn}}. The team guest-starred in the original ComicBook/WildCATsWildStorm miniseries. Doc Rocket and Johnny Panic both owe their existence entirely to Creator/AlanMoore's ''ComicBook/{{Supreme}}'' - they didn't appear directly but are related to characters introduced therein. Diehard ''did'' appear in ''Supreme'', as a member of the [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] Allies of Justice (along with Superpatriot from ''ComicBook/SavageDragon''). And Suprema and Twilight, the series' Supergirl and Robin stand-ins, were members of the team during Moore's run.
** Currently, ''ComicBook/{{Invincible}}'' shoulders a lot of weight when it comes to establishing a larger Image universe. Characters from Kirkman's other books popping up frequently, and big events (like the funeral of the Guardians of the Globe or the Invincible War) feature just about anyone who's anyone in the company at the time. At one point Mark was even a member of the Pact, a team consisting of him, [[ComicBook/NobleCauses Zephyr Noble]], ComicBook/{{Firebreather}}, and ComicBook/ShadowHawk.
* ''ComicBook/JudgeDredd'' and its spinoffs share a universe with ''ComicBook/StrontiumDog'', ''ComicBook/RogueTrooper'', ''ComicBook/HarlemHeroes'' and their respective spinoffs. Earlier stories also suggested that ''Invasion!/ComicBook/{{Savage}}'', ''ComicBook/ABCWarriors'', ''ComicBook/RoBusters'' and ''ComicBook/{{Flesh}}'' were part of this universe, but these have subsequently been retconned out.
* ''ComicBook/ArchieComics'', ''ComicBook/SabrinaTheTeenageWitch'', and ''ComicBook/JosieAndThePussycats'' are all a part of one ''Franchise/{{Archie|Comics}}'' universe and frequently crossover.

* The ComicBook/MassiveVerse, primarily published through Image Comics[[note]]''Inferno Girl Red'' is a self-published Kickstarter project[[/note]], is a shared universe that began with ''ComicBook/RadiantBlack'' in 2021 before formally launching in 2022 with a one-shot and its second series, ''Rogue Sun''. All three of its primary creators are fans of {{Sentai}} who have worked on licensed comics for Sentai properties, and it is a big part of the visual design of the universe.

* The action heroes of ''ComicBook/FutureQuest'' are part of a multiverse, though it is shown that ''WesternAnimation/JonnyQuest'', ''WesternAnimation/{{Birdman}}'' and ''Mightor'' exist in the same Earth.

** ''WesternAnimation/HarveyBirdmanAttorneyAtLaw'', a satirical sequel to ''WesternAnimation/{{Birdman}}'', is consisted of a cast from various Hanna-Barbera cartoons.

* A lot of Happy Madison productions [[https://www.youtube.com/watch?v=tjbrKseSURU share a universe]], with InexplicablyIdenticalIndividuals given the differing roles of Creator/AdamSandler. These include ''Film/HappyGilmore'', ''Film/BillyMadison'', ''Film/BigDaddy'', ''Film/TheWaterboy'', ''Film/TheWeddingSinger'', ''Film/LittleNicky'', ''Film/JoeDirt'' and its sequel, ''Film/MrDeeds'', ''WesternAnimation/EightCrazyNights'', ''Film/TheLongestYard'', ''Film/GrandmasBoy'', ''Film/{{Click}}'', ''Film/INowPronounceYouChuckAndLarry'', ''Film/GrownUps'' and its sequel, and ''Film/ThatsMyBoy''

** The minister officiating the marriage ceremony in ''Film/ThatsMyBoy'' is Father Shakalu, who was known as Doctor Shakalu in ''Film/GrandmasBoy''.

** [[WesternAnimation/BeautyAndTheBeast Belle]] makes a brief cameo in ''WesternAnimation/TheHunchbackOfNotreDame''.

* You think Creator/{{Capcom}}'s ''VisualNovel/AceAttorney'' universe is crazy? HA. ''You have no idea.''
** ''Ace Attorney'', past [[VideoGame/ProfessorLaytonVsPhoenixWrightAceAttorney its crossover]] with ''[[VideoGame/ProfessorLaytonVsPhoenixWrightAceAttorney Professor Layton]]'', is confirmed by WordOfGod to include ''VideoGame/GhostTrick'', and, by inclusion of the Republic of Borginia, is implied to also include ''VideoGame/DinoCrisis'' (the first game being set in the Borginian Republic). [[note]]Both ''Ace Attorney'' and ''Dino Crisis'' share creator Shu Takumi.[[/note]]
** Interestingly, ''Dino Crisis'' has several crates featuring the [[Franchise/ResidentEvil Umbrella Corporation logo]]. Further, [[LightGunGame Light gun shooter]] GaidenGame ''Dino Stalker'' is actually the third installment of ''Resident Evil'''s spin-off series ''Gun Survivor'', featuring Umbrella {{Easter Egg}}s in the form of the "Woman Drawing Water" statue seen in [[VideoGame/ResidentEvil1 the Spencer Mansion's exhibition room]] and an abandoned Umbrella building.

** ''Franchise/SuperSentai'' also is a shared universe with frequent crossovers. It also shares a universe with several other {{Tokusatsu}} shows including ''Franchise/KamenRider'' (though this can create a snarl since not all ''Kamen Rider'' shows share a universe as previously stated) and ''Series/MetalHeroes''.

Strangely however, the 45th anniversary series ''Series/KikaiSentaiZenkaiger'' depicts all the previous series as each being in a separate universe, even though this contradicts what was established in the 35th anniversary series.

* Film/TheConjuringUniverse is an interrelated horror films that started with ''Film/TheConjuring'', based on the purported cases of real-life paranormal investigators Ed and Lorraine Warren. It eventually explored other things, though they are still given a tangential connection with the Warrens.

*** ''Webcomic/QuestionableContent'' as well, though mainly as the odd cameo (and an implied spacewarp between the Shortpacked store and Coffee of Doom, which is actually pretty reasonable by QC standards at least - it's since been established that the coffeshop near Shortpacked which has the same layout, staff, clientele and espresso dinosaur as Coffee of Doom is called Coffeeright Theft).

* The final episode of ''WesternAnimation/CampLazlo'' implies that the show takes place in the same universe as ''WesternAnimation/RockosModernLife'' with the appearance of a character who is clearly meant to be an older version of Heffer.
