History Main / SharedUniverse

** ''VideoGame/MegaManBattleNetwork'' and ''[[VideoGame/MegaManStarForce Star Force]]'' both share a timeline [[AlternateContinuity separate]] from the original series.

* The Website/ThatGuyWithTheGlasses Universe which consists of all the website's shows, WebVideo/AskThatGuyWithTheGlasses, WebVideo/AtopTheFourthWall, WebVideo/BadMovieBeatdown, WebVideo/TheCinemaSnob, WebVideo/DiamandaHagan, WebVideo/FamiliarFaces, WebVideo/JesuOtaku, WebVideo/TheNostalgiaChick, WebVideo/TheNostalgiaCritic, WebVideo/ThatDudeInTheSuede, and numerous others, as well as ''WebVideo/TheAngryVideoGameNerd''.

* ''WesternAnimation/{{Rugrats}}'', ''WesternAnimation/TheWildThornberrys'', and ''WesternAnimation/RocketPower''.

** And since WesternAnimation/PinkyAndTheBrain also happen to share the same universe as the above shows, they're counted as part of it as well.

* WordOfGod confirms that ''WesternAnimation/TransformersPrime'' and ''WesternAnimation/TransformersRescueBots'' take place in the same universe. This was finally confirmed in-universe by the ''Rescue Bots'' episode "Bumblebee To The Rescue". It's also the reason ''Rescue Bots'' is set on an island and ''Prime'' is set in the American southwest. This allows the two shows to reference each other and interact while still being seperate.

** Furthermore, EdEddNEddy appeared in an episode of ''FostersHomeForImaginaryFriends''.

* ''ComicBook/ArchieComics'', ''ComicBook/SabrinaTheTeenageWitch'', and ''ComicBook/JosieAndThePussycats'' all share a universe and frequently crossover.

* ''Manga/HourouMusuko'' shares a universe with ''Shikii no Juunin''.

* A subtle link exists among four of Marvel and Sunbow's MerchandiseDriven 1980s cartoons — the character of Hector Ramirez, a [[NoCelebritiesWereHarmed thinly veiled]] {{parody}} of Geraldo Rivera, appears in ''WesternAnimation/{{Inhumanoids}}'', ''WesternAnimation/GIJoeARealAmericanHero'', ''WesternAnimation/TheTransformers'' and ''WesternAnimation/{{Jem}}''; [[http://buzzdixon.com/media/the-many-faces-of-hector-ramirez/ his creator states that this forces them into the same universe.]]
** It goes deeper in that in some cases. 3rd-season Autobot ally Marissa Fairborn has been explicitly stated to be the daughter of Joes Flint and Lady Jaye, and an episode of the same season featured a villain called "Old Snake" who was clearly Cobra Commander.
** In Transformers Animated: The [=AllSpark=] Almanac II, Vector Prime confirms that all these shows and C.O.P.S. (In the toyline, the hero Checkpoint is a descendant of Beach Head) take place in the Transformers generation 1 continuity.
* Since the ''WesternAnimation/LooneyTunes'' characters are the teachers to the ''WesternAnimation/TinyToonAdventures'' characters, this makes an obvious example. A not-so-obvious addenum to this is that the ''Looney Tunes'' characters also made several cameos on ''WesternAnimation/{{Animaniacs}}'' and ''WesternAnimation/{{Histeria}}'', which therefore means they too share the same universe.

** Even without counting the Smash Bros games and other obviously non canon crossover games, there have been many more signs that most Nintendo franchises share a universe. If you count all of the various cameos in canon Nintendo games, Legend of Zelda, Mario Bros, Kirby, Metroid, Punch Out, and possibly more all share a universe, though it has not been confirmed. There are actually are several videos on youtube like this one https://www.youtube.com/watch?v=8vRpnVDMRu4 that show how just about all video games could be in the same universe.

* The ''Franchise/SuperMarioBros'' and ''Franchise/DonkeyKong'' series exist in the same universe, as shown through Donkey Kong, Diddy, Dixie, and Funky appearing in ''Mario'' spin-offs, as well as Mario and Yoshi appearing in ''Donkey Kong Country 2''. Additionally, due to first appearing in ''Super Mario World'' and ''Super Mario Land 2'' respectively, the ''Yoshi'', ''VideoGame/WarioLand'', and ''VideoGame/WarioWare'' series are also part of the expanded ''Super Mario'' universe. The entire SharedUniverse of ''Mario'', however, is much, MUCH larger.
** In addition to this, Rare's games share a universe with Donkey Kong (as caused by ''VideoGame/DiddyKongRacing'' having Banjo and Conker in it and references to Donkey Kong and Mario in their other games in the Nintendo 64 era). This not only adds ''VideoGame/BanjoKazooie'' and ''VideoGame/ConkersBadFurDay'' into the ''Mario'' universe, it leads off into what ''Website/DKVine'' call the DKU, where the presence of Roystein the Goldfish in yet more games integrates in ''Viva Pinata'' and ''Grabbed by the Ghoulies'', where Donkey Kong in ''VideoGame/PunchOut'' integrates in ''Punch Out'' and where Mr Pants can be linked to Mario by way of proxy via two franchises. Or where ''VideoGame/StarFox'' apparently exists alongside Donkey Kong thanks to Tricky the Triceratops... It's a really, really confusing situation, made more complex by Rare getting bought out by Microsoft.

** Ironside references the Mortal Cup.

** Oliver Garneau from ''Black Flag's'' [[FramingDevice Frame Narrative]] leaves for Chicago (Where ''Watch_Dogs'' is set) during the game. [[spoiler:In ''Watch_Dogs'', [[PlayerCharacter Aiden]] kills him as part of an optional side mission under mysterious orders from]] [[spoiler:[[Characters/AssassinsCreedTheAssassins "The Brotherhood"]].]] There are also several references to Abstergo Industries, and, at one point, a child can be found playing ''VideoGame/AssassinsCreedIIILiberation'', which is a video game produced by Abstergo Entertainment in-universe.
** ''VideoGame/FarCry'' is in on the action, too. One mission in ''VideoGame/FarCry3'', which discusses "strange scientists" and "genetic memories", takes you to an abandoned Abstergo laboratory. ''VideoGame/FarCry2'' is definitely set in the same universe as its sequel, but whether the original or [[VideoGame/FarCry4 the upcoming fourth entry]] are still in the universe have yet to be seen.

* [[VideoGame/Gradius]] takes places in the same universe as CardGame/YuGiOh (the card game, not the anime, although it also is a video game in the anime universe) [[http://yugioh.wikia.com/wiki/Konami_Arcade_Games as shown here]]

* SCPFoundation takes place in the same universe as the WanderersLibrary. Also, due to the fact that SCPFoundation "has no cannon" it can share the same universe with anything, since it is up to the reader to decide what is or isn't cannon. Several crossover stories have been written by various authors.

** Other film companies are [[FollowTheLeader following Marvel Studios' lead]], creating their own cinematic universes for comic-book properties they own the film rights to. Warner Bros is creating a cinematic universe for all their DC Comics properties, beginning with the film ''Film/ManOfSteel''. Fox is setting their new ''Franchise/FantasticFour'' films in their established ''Film/{{X-Men}}'' film continuity, effectively making a rival cinematic universe of Marvel properties.

* Cartoon Network has a few. Assuming that ''all'' (or at least most) of its original cartoons don't share the same universe (which is hinted at in some commercials) {{crossover}} episodes, guest star appearances, and CanonImmigrants have resulted in ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', ''WesternAnimation/EvilConCarne'', and ''WesternAnimation/CodenameKidsNextDoor'' sharing one. ''WesternAnimation/DextersLaboratory'' and ''WesternAnimation/ThePowerpuffGirls'' share another, proven by the appearances of Major Glory and Valhallen in one episode of the later show.

* All three current Marvel Animation shows, ''WesternAnimation/UltimateSpiderMan'', ''WesternAnimation/AvengersAssemble'', and ''WesternAnimation/HulkAndTheAgentsOfSMASH'', seem to take place in the same universe. BroadStrokes aside, they seem to take place at different times given how Hulk speaks differently in each of them (from HulkSpeak in ''Ultimate Spider-Man'' to speaking in complete sentences in ''Agents of SMASH'', with a transitional speech pattern for ''Avengers''). At the very least, they have similar head writers (Paul Dini, Man of Action) and share the same voice actors for their vast amounts of characters across the shows (ie, Drake Bell as Spider-Man, Adrian Pasdar as Iron Man, Fred Tatsciore as Hulk, and Travis Willingham as Thor).

* ''ComicBook/AtomicRobo'' is apparently set in the same universe as ''VideoGame/TeamFortress2'' according to a recent crossover comic.

** Arguably ''Series/AndyBarkerPI'' as well because Guy Halvorson was the owner of Doublemeat Enterprises, which Buffy previously worked for.

* ''Franchise/StreetFighter, VideoGame/FinalFight'', ''VideoGame/SaturdayNightSlamMasters'' and ''VideoGame/CaptainCommando'' take place in the same universe. ''VideoGame/RivalSchools'' and ''VideoGame/{{Darkstalkers}}'' may also be part of it.

** The first ''Rival Schools'' features Sakura as a playable character (although, her blood type is different from the one given in the ''Alpha'' series). Moreover, the ''Nekketsu Seisyun Nikki'' spin-offs has Hinata studying the "Ken Masters style of Karate" and Iinchou/Chairperson learning "Saikyou-Style" through mail. On the other hand, there are a few date discrepancies according to the first game's intro and Sakura's storyline (in which she's yet to meet Ryu, placing the series pre-''VideoGame/StreetFighterAlpha 3'').
** In ''Night Warriors: Darkstalkers Revenge'', Felicia claims she wants Blanka as the leading man in her new movie. Among various Capcom characters, Morrigan, Felicia, Hsien-Ko, Mei-Ling, and Lord Raptor can be seen on [[http://capcom.wikia.com/wiki/File:StreetFighterAlpha2-USA(Ken).png Ken's stage]] in ''VideoGame/StreetFighterAlpha 2'', although there's a distinct possibility these are very convincing cosplayers.
** While not part of the main ''Street Fighter'' continuity, the Arika-developed ''VideoGame/StreetFighterEX'' games shares a couple of characters (Allen and Blair) with their independently developed arcade game ''FightingLayer''.

* ''VideoGame/ProjectXZone'' is a MassiveMultiplayerCrossover so it deals with characters from multiple different universes together, seemingly [[AvertedTrope averting this trope]]. But on the other hand, some characters from separate series entirely are aware of each other, suggesting that games from different companies entirely might share the same universe.
** ''Franchise/StreetFighter'' appears to be in the same universe as ''VideoGame/RivalSchools'', ''VideoGame/{{Tekken}}'', ''VideoGame/FightingVipers'' and ''VideoGame/VirtuaFighter'' by virtue of characters apparently not only hearing of each other, but actually knowing each other and being aware of other fighting game tournaments. They're also aware of other characters not from the same genre by virtue of being aware of current events, especially Chun-Li, so they're also in the same universe as ''Franchise/ResidentEvil'', ''VideoGame/DeadRising'', ''VideoGame/ZombieRevenge'' (and ''VideoGame/HouseOfTheDead'' by extension) and ''Die Hard Arcade''. Then as it turns out, the Makai exists in this same Earth, meaning that they all take place in the same universe as ''VideoGame/{{Darkstalkers}}''. Who are aware of the exploits of Sparda, extending the universe to ''Franchise/DevilMayCry''. Dante idolizes Arthur as a legendary demon hunter, making ''VideoGame/GhostsNGoblins'' ''also'' part of that very same universe. The demons also seem to be aware of Valkyrie from ''Legend of Valkyrie''. At this point, why have a plot about different universes coming together?
** That's not the only shared universe, though. Games from alternate histories and alternate futures are part of separate timelines, for obvious reasons. Tron is aware of the existence of X and Zero, confirming that ''VideoGame/MegaManLegends'' is in the same universe as ''VideoGame/MegaManX'' just like they do in the original canon. But Devilotte of ''VideoGame/{{Cyberbots}}'' appears to know of Tron, putting that game in the same universe, and then [[RobotGirl KOS-MOS]] also appears to know of X and Zero, possibly putting even ''VideoGame/{{Xenosaga}}'' in the same universe as the ''Mega Man'' games.
** Even further, the two shared universes may actually be one due to the fact that Kite and Blackrose of ''Franchise/DotHack'' are surprised that they're walking around the real world using their MMO characters. Said real world being the one that all the FightingGame characters are a part of. Then when they end up back in the MMO along with everyone else, they try exiting and end up in [[VideoGame/MegaManX4 Cyber Peacock's stage]] which was apparently where some of the MMO's servers are located. And on top of that, Neneko of ''VideoGame/{{Yumeria}}'' recognizes Kite and Blackrose on sight, adding one more game series to the Shared Universe. The number of games that aren't part of it at this point are few.
** ''Project X Zone'' is a continuation of ''VideoGame/NamcoXCapcom'' (and ''VideoGame/EndlessFrontier'' by proxy), which already established that, if only for the sake of that crossover's continuity, all involved series exist in the same universe, only separated by varying layers of time and space. As a large part of the ''[=NxC=]'' cast returned for ''Project X Zone'', a few of these instances can be chalked up to "X and Y character [[AlreadyMetEveryone already]] [[ContinuityNod met]]." There's also no word on if [[VideoGame/CapcomVsWhatever other previous crossovers]] have any bearing on the game (the ''VideoGame/MarvelVsCapcom'' series and ''VideoGame/TatsunokoVsCapcom'' in particular, where many of the characters here already crossed paths or were at least aware of worlds other than their own[[note]]one such example being [[VideoGame/{{Darkstalkers}} Morrigan]] knowing of VideoGame/ViewtifulJoe due to a past correspondence with Alastor, who is confirmed to be the spirit of the Devil Arm of the same name from the original ''Franchise/DevilMayCry'' in the [=PS2=] port of ''Viewtiful Joe''[[/note]]), although there may be support for the idea in-game: [[VideoGame/FightingVipers Bahn]] recognizes [[VideoGame/VirtuaFighter Akira and Pai]] due to Sega's own non-canon crossover, ''VideoGame/FightersMegamix''.
* ''VideoGame/ProfessorLaytonVsAceAttorney'' seems to indicate that ''Franchise/ProfessorLayton'' and ''Franchise/AceAttorney'' share a universe as the game fits well enough into both continuities. With Hershel Layton being British and Phoenix Wright being American (or Japanese), it makes sense for the series to have relatively little overlap until Wright visits the UK.

* Many of the animated works of Creator/{{Pixar}} seem to fall into this category, mainly because of the countless references in their films and shorts that overlap with each other. The Pizza Planet Truck from ''WesternAnimation/ToyStory'' is the best example of this, which has showed up in nearly every feature film of theirs.

* Franchise/UniversalHorror is one of the earliest cinematic examples. From the 1930s to the 1950s, [[Creator/{{Universal}} Universal Pictures]] (later Universal Studios) released various horror films featuring [[Film/{{Dracula1931}} Dracula]], [[Film/{{Frankenstein1931}} Frankenstein's Monster]], [[Film/TheWolfMan1941 The Wolf Man]] and others, and eventually had them [[{{Crossover}} cross over]] with each other, creating or at least codifying the MonsterMash. While more recent Universal horror/adventure films like ''[[Film/TheMummyTrilogy The Mummy]]'' trilogy, ''Film/VanHelsing'' and the 2010 version of ''[[Film/TheWolfman2010 The Wolfman]]'' didn't share a universe, as of 2014 Universal is trying to do this again with ''Film/DraculaUntold'' and an upcoming ''Mummy'' reboot.

* Franchise/UniversalHorror is one of the earliest cinematic examples. From the 1930s to the 1950s, [[Creator/{{Universal}} Universal Pictures]] (later Universal Studios) released various horror films featuring [[Film/{{Dracula1931}} Dracula]], [[Film/{{Frankenstein1931}} Frankenstein's Monster]], [[Film/TheWolfMan1941 The Wolf Man]] and others, and eventually had them [[{{Crossover}} cross over]] with each other, creating or at least codifying the MonsterMash.

* ''Series/{{JAG}}'', ''First Monday'', ''Series/{{NCIS}}'', ''Series/NCISLosAngeles'' and the new ''Series/HawaiiFiveO'' are a shared world, as evidenced by Kensi's presence in Hawaii.
