[[caption-width-right:350:The movies may show you [[LawOfConservationOfDetail a dozen planets]]; but the [[Franchise/StarWars galaxy far, far away]] is in fact a [[http://images.wikia.com/starwars/images/1/10/MainGalaxy.png pretty large place.]]]]

TheVerse may branch out across different media as the {{fandom}} demands. There may be comic books, tie-in novels, movies, novelizations, {{video game}}s, etc. Sometimes the TV show is itself a branching-out of a [[TheVerse verse]] that originated in another form (such as comics, as in the MarvelUniverse or TheDCU).

Expanded Universe refers to everything that is not the primary medium. All that other stuff.

This can create a schism in fans. Some believe the entire Expanded Universe is {{canon}}. Others reject it all. Others pick and choose based on closeness to the writers of the primary medium. Expanded Universe material is usually written so that it can be fit in to the {{canon}} without having to alter the {{canon}} itself. However, later developments in the actual series can make it definitively out of {{continuity}}, especially when the main series decides to explain a mystery (such as a character's future) in a way that contradicts the Expanded Universe.

Even if it isn't {{canon}}, the Expanded Universe often serves as a place to apply ScotchTape to the {{canon}} through {{Retcon}}s; this may verge on professional-grade FanWank.

The term comes from ''Franchise/StarWars'', which has an extensive Expanded Universe covering events before, during, and after the films. The Franchise/StarWarsExpandedUniverse even has its own page.

Note: the "primary medium" is usually the original one, but not always. For instance, few would dispute that the primary medium of the {{Buffyverse}} is the [[Series/BuffyTheVampireSlayer 1997 TV show]], not the [[Film/BuffyTheVampireSlayer 1992 movie]] (which is only {{canon}} for the television series in the form of its altered comic book adaptation which is based off of Joss' original script for it).

After a show's cancellation, the Expanded Universe may become the only place to get new material involving TheVerse (outside of FanFic, of course), continuing the {{canon}} in the minds of the readers/viewers. However, if a show is later [[UnCanceled brought back]], this "new {{canon}}" may be cancelled out, creating yet more conflict.

Sometimes [[CanonForeigner a character from the Expanded Universe]] is so popular (or just so good) that they get put into the official {{continuity}} of the original medium. This character is known as a CanonImmigrant. If elements from the EU are well-recieved enough, they may be permanently integrated, [[ReVision revising]] or [[ReWrite rewriting]] the official continuity resulting in a {{Retcanon}}

Compare AdaptationExpansion, which concerns never before seen developments of certain aspects in a ''retelling'' of one specific work or set of works in a franchise when they're adapted into another medium. See also RestrictedExpandedUniverse.

Please do not abbreviate it to EU, which is an abbreviation for UsefulNotes/TheEuropeanUnion.

See also {{sequel}}s, {{prequel}}s, {{interquel}}s and {{spinoff}}s for works that share same {{continuity}} ''and'' the same medium as the primary work (i.e. a VideoGame with a {{prequel}} game, or an {{anime}} series that spins off another series).

Not to be confused with the Creator/RobertAHeinlein anthology known as ''Expanded Universe''.

[[folder:Anime and Manga]]
* There are select fans of ''Manga/{{Naruto}}'' that consider the databooks as Expanded Universe.
* ''Franchise/{{Gundam}}'', as a [[LongRunners 30-year franchise]], has '''lots''' of manga, novels, {{video game}}s, etc., including such popular titles as ''[[Manga/MobileSuitCrossboneGundam Crossbone Gundam]]'' and ''[[Manga/MobileSuitGundamSeedAstray Gundam SEED Astray]]''. [[WordOfGod According to]] {{Sunrise}}, only animated works are considered {{Canon}}, meaning that everything Expanded Universe isn't, no matter how closely it cleaves to {{continuity}} (and, in the case of ''Crossbone'', in spite of the fact that it was written by [[YoshiyukiTomino the creator of the franchise himself]]).
* Light novels are this for many anime shows, telling original stories that are sometimes adapted as ''filler''.
[[/folder]]

[[folder:Comics]]
* ''ComicBook/TheWalkingDead'' has three {{prequel}} novels ([[Literature/TheWalkingDeadRiseOfTheGovernor Rise of the Governor]], [[Literature/TheWalkingDeadTheRoadToWoodbury The Road to Woodbury]], and [[Literature/TheWalkingDeadFallOfTheGovernor The Fall of the Governor]]) and an [[VideoGame/TheWalkingDead episodic adventure video game]] with two seasons by TelltaleGames that are all set in the same universe as the comic book.
[[/folder]]

[[folder:Fan Fics]]
* Daneel Rush, the author of the ''FanFic/TamersForeverSeries'' has put a ''lot'' of effort into expanding the digimon mythology, creating a mythos that combines computer programming codes with real world mythology and religious beliefs.
** The first glimpse comes in the form of Takeru's exposition during ''Silent Sorrow'', but even more info can be found in the GOSPEL wiki ([[LateArrivalSpoiler curious tropers should beware heavy unmarked spoilers when browsing these notes]])
* ''FalloutEquestria'' also has its own side stories.
* The ''Literature/{{Discworld}}'' has been expanded in fanfic, most thoroughly in the works of author A.A. Pessimal. From bare bones and hints in the canon, there is now a fairly fully realised "South Africa", with all the knobs turned UpToEleven in approved Pratchett mode. Rimwards Howondaland is stuck in TheApartheidEra, but complicated by the existence of other sentient species as well as human. This is explored in tales such as ''[[Fanfic/TheBlackSheep The Black Sheep]]'' and ''[[Fanfic/WhyAndWere Why And Were]]''. Elsewhere, the Foggy Islands, referenced in the canon, have become a more realised set of glimpses of a Discworld UsefulNotes/NewZealand, and a place called '''Aceria''' is emerging as another troublesome and quaint former colony, stretching, as its national anthem tells us, ''from Hub to shining sea''. Aceria is mainly an {{Expy}} of UsefulNotes/{{Canada}}, but (just as Agatea is a portmanteau of Japan, China and Thailand) is expanding to have a marked streak of {{Eagleland}} to it. Aceria has a troublesome and stroppy [[UsefulNotes/{{France}} Quirmian-speaking]] enclave to it, and has given the Disc "Country and Widdershins" music and line-dancing.
[[/folder]]

[[folder:Film]]
* ''Film/BladeRunner'' spawned three novel sequels and a [[VideoGame/BladeRunner videogame]] taking place in the film's universe -- as well as another film, ''Soldier'', which (unofficially, due to rights issues) also takes place in the ''Blade Runner'' universe.
* ''Franchise/PiratesOfTheCaribbean'' has spawned a number of novels, short films, comics, and games.
* The aforementioned Franchise/StarWarsExpandedUniverse. All of it's vetted by either Creator/GeorgeLucas or his employees, who have at times vetoed plot points, new characters, and entire stories. There are indeed people whose actual paid jobs are purely to assist in the management of all the disparate plot points in this [[CashCowFranchise vast, money-generating machine]]. Even in cases where an Expanded Universe story blatantly contradicts either the films (on account of many stories being written before the {{prequel}}s existed) or the rest of the Expanded Universe, it usually remains {{canon}}: in most cases the aforementioned employees are tasked with forming as many {{retcon}}s as needed to resolve the discrepancy.
** Creator/GeorgeLucas views only his films (and possibly the ''WesternAnimation/StarWarsTheCloneWars'') as canon, referring to Expanded Universe works as a parallel universe. Leeland Chee, went against George Lucas' statements many times by claiming that just about everything is canon (they have a policy to determine the exceptions), then eventually said that there was a "Films Only" canon, and a "Films and EU" canon, this being before the ''WesternAnimation/StarWarsTheCloneWars'' show. He then added that whichever is "more canon" is ultimately up to the tastes of the individual fan.
* The cult favorite series ''KolchakTheNightStalker'' has inspired a set of follow-on novels featuring the series characters. The latest one this editor can find was published in 2007--33 years after cancellation of the original series!
* ''Film/{{Darkman}}'' spawned a series of (quite good) novels, and a short-lived comic book series. Recently the character was licensed to Dynamite Comics, who will be publishing original stories. They've already put out an ''Franchise/EvilDead'' crossover.
* Few people know that the film ''Film/WhoFramedRogerRabbit'', itself based (very loosely) on the Gary K. Wolf novel ''WhoCensoredRogerRabbit?'', has some nicely concise Expanded Universe material. The novel ''Who P-P-P-Plugged Roger Rabbit?'' (it's really spelled that way, because Roger stutters his p's) is a direct {{sequel}} to the film, and gives us plenty of more material on how the series' world functions, and much more about the life and family of Eddie Valiant. There are also comics and a couple of short stories.
* ''Franchise/{{Alien}}'' and ''Franchise/{{Predator}}'' have their own Expanded Universe, including several cross-over miniseries published by Dark Horse Comics during the late 80s and 90s. The first three miniseries for Aliens were originally a continuation of [[Film/{{Aliens}} the second Alien movie]]; however, the release of ''Film/{{Alien 3}}'' rendered the events of those series incompatible with the movie's {{continuity}} since it killed Newt and Hicks at the beginning of the movie, and Ripley at the very end. Dark Horse got around this by rereleasing the series in graphic novel format, with new names for the series as well as [[RetCon renaming Newt as Billie and Hicks as Wilkes]], and stuck with using original characters after that. There have also been many ''Franchise/{{Alien}}'' and ''Franchise/{{Predator}}'' novels and {{video game}}s released, including a few ''AlienVsPredator'' games for the PC.
** A good number of these materials are now also CanonDiscontinuity thanks to ''Film/{{Prometheus}}''.
* Each of the eight major characters from ''Film/RepoTheGeneticOpera'' have their own Myspace page. Whatever happens there is considered {{canon}}. Rotti is understandably a very busy man and only occasionally present, but his children are there whenever they're supposed to be working, and Grave-Robber apparently drums up a lot of new clientele through the site.
* Not counting (though some do) the InNameOnly [[Series/FridayThe13thTheSeries television series]], ''Franchise/FridayThe13th'' has a surprisingly large number of books and comics.
* Other New Line Cinema horror properties such as ''Franchise/ANightmareOnElmStreet'', ''Film/FinalDestination'' and ''Franchise/TheTexasChainsawMassacre'' also have a large number of novels, short story collections, comic books, and in Freddy's case, [[Series/FreddysNightmares a television series]].
* ''Franchise/{{Hellraiser}}'' has a surprisingly huge, detailed Expanded Universe, primarily due to many of the cast and crew from the film series contributing, even series originator Creator/CliveBarker, and Peter Atkins (the writer of the [[Film/HellboundHellraiserII second]], [[Film/HellraiserIIIHellOnEarth third]] and [[Film/HellraiserBloodline fourth]] films).
* JimHenson's non-Muppet fantasy films each have expanded universe material in the form of graphic novels.
** ''TheDarkCrystal'' had a two-volume prequel, the OELManga ''Legends of the Dark Crystal'', via {{Tokyopop}} over 2007-10. Archaia Publishing introduced its own prequel series, ''The Dark Crystal: Creation Myths'', in 2011; this is set to be a trilogy and is actually being overseen by the film's production designer Brian Froud.
** ''{{Labyrinth}}'' had a OELManga sequel from {{Tokyopop}}, the four-volume ''ReturnToLabyrinth'', over 2006-10. Archaia is working on a prequel presenting the origin story of fan-favorite [[DavidBowie Jareth the Goblin King]]; while quality concerns are keeping that in DevelopmentHell for now, this hasn't stopped one-shot stories from appearing in the company's Free Comic Book Day compilations ("Hoggle and the Worm" in 2012, and a Sir Didymus story in 2013). Interestingly, the planned prequel won't be compatible with ''Return to Labyrinth''.
* Although not actually canon, ''Film/RedDawn1984'' got an Expanded Universe in the form of ''RedDawnPlus20''.
* ''Film/{{Tron}}'' spent years as a CultClassic, but its revival [[OlderThanTheyThink began in 2003]] with ''[[VideoGame/TronTwoPointOh TRON 2.0]]'' and the ''Ghost in the Machine'' graphic novel (now CanonDiscontinuity). The "canon" timeline now includes both ''Film/{{Tron}}'' and ''Film/TronLegacy''. It also contains the ''Betrayal'' graphic novel, the ''Flynn Lives'' AlternateRealityGame, ''VideoGame/TronEvolution'' (and ''Tron Battle Grids'' in that Jalen was said by Word of God to be the champion of that game), and the animated series ''WesternAnimation/TronUprising''.
[[/folder]]

[[folder:Literature]]
* The ''Franchise/CthulhuMythos'' is a particularly informal Expanded Universe based around the works of Creator/HPLovecraft, all writers (and TabletopGame/CallOfCthulhu game designers) after him are generally considered to be outside "The Mythos Proper".
* ''Literature/WarriorCats'' has 13 comic books, 2 plays and 4 guidebooks (as well as one that was [[WhatCouldHaveBeen cancelled]]). These are all canon, being written by the authors themselves, except possibly ''Brightspirit's Mercy'', which happens in the middle of a book's story rather than in one the series' plentiful {{time skip}}s.
* There exists an interesting phenomenon: a bootleg Expanded Universe, created in the cracks between copyright laws of different countries. An example is the Expanded Universe several Russian fantasy writers created around Creator/JRRTolkien's works: illegal everywhere in the English-speaking world, published officially back in the Motherland. It includes such works as ''FanFic/TheBlackBookOfArda'' and ''FanFic/BeyondTheDawn''.
* Tellarium Games back in the early 80's made text adventure sequels to ''Fahrenheit451'', ''Dragonworld,'' and the GreenSkyTrilogy woth the blessing of, and heavy input from, the series authors, making them at least semi-canonical (and in the case of BelowTheRoot, ''definitely'' canonical) sequels.
[[/folder]]

[[folder:Live Action TV]]
* The ''Franchise/DoctorWhoExpandedUniverse'' may in fact be {{Canon}} to the TV series as two episodes directly reference it in {{Mythology Gag}}s. Other parts contradict it. But then the Franchise/{{Whoniverse}} (Expanded and otherwise) tends towards BroadStrokes {{continuity}} and to a large extent anything goes within it. Former producer Creator/RussellTDavies has stated that he considers the ''AudioPlay/BigFinishDoctorWho'' {{audio play}}s to be in-{{continuity}}. That statement was made back when the audio plays explicitly broke from {{continuity}} with the books; they've since been amended into a single {{continuity}} by the audio play ''The Company of Friends''. The Series 3 episodes "Human Nature" and "Family of Blood" have been acknowledged as an adaptation of the Seventh Doctor Literature/DoctorWhoNewAdventures novel ''Human Nature'' (the novels themselves form two distinct and only semi-compatible [[{{Continuity}} continuities]]) and, confusing things yet further, some writers of the spin-off material took the view they took place in {{Alternate Universe}}s to each other.
* ''Series/DoctorWho'''s spin-off ''Series/{{Torchwood}}'' has its own expanded materials in the form of novels, magazine strips, and audios. Perhaps the most interesting one so far is the magazine strip "Shrouded", penned by Gareth David-Lloyd (Ianto Jones' actor). [[spoiler:Our Ianto is quite dead, but an evil Ianto from an alternate timeline is very much alive, and saw the funeral. Is this {{Canon}}?]]
* The novel-based ''StarTrekExpandedUniverse'', published by Simon & Schuster, primarily carries forward the future history of ''Series/StarTrekTheNextGeneration'', ''Series/StarTrekDeepSpaceNine'', and ''Series/StarTrekVoyager''. It's been given full rein over [[Franchise/StarTrek Trek]] stories post-''Nemesis'', as it's likely that version of the [[Franchise/StarTrek Trek]] universe won't appear on-screen again. The ''Franchise/StarTrek'' Expanded Universe most recently includes a fan series called ''[[http://www.wired.com/wired/archive/13.12/startrek.html Star Trek: New Voyages]]'', which is attempting complete the "five year mission" of [[Series/StarTrekTheOriginalSeries the original series]]. It's being supported by a number of people with professional links to the official series runs, most notably Walter Koenig and GeorgeTakei, who reprise their roles of Chekov and Sulu, respectively.
* ''Series/{{Lost}}'' has a relatively small Expanded Universe so far -- a few books, two AlternateRealityGames, and a VideoGame. The only one of these that's been declared {{canon}} is the first ARG, ''The {{Lost}} Experience'' -- and that only applies to the backstory information given relating to the series, not the main plot.
* ''Series/{{Glee}}'' has its own {{prequel}} book now.
* ''Series/{{Heroes}}'' has a small Expanded Universe with comic books and graphic novels, not much of it {{canon}} and [[RetCon the rest getting smaller the longer the show goes on.]] Now that the show itself has been canceled, the Expanded Universe presumably has free rein again.
* ''Series/BabylonFive'' has Expanded Universe in the form of Role-playing game sourcebooks. There are {{Canon}}ical comics and a lot of novels. Of the novels, only ''To Dream in the City of Sorrows'', the ''Psi Corps'' trilogy, the ''Passing of the Techno-mages'' trilogy, the ''Legions of Fire'' trilogy, and the Anna Sheridan plot of ''The Shadow Within'' are canon. The John Sheridan plot of ''The Shadow'' Within is not canon. That's right, canon and non-canon in the same book.
* ''Series/BuffyTheVampireSlayer'' has many novels and comic books written by writers of the series that are of varying apocryphal status, and a [[JossWhedon Whedon-helmed]] comic-book series (along with a similar comic-book series for its {{spinoff}} series ''Series/{{Angel}}'') that's considered the {{canon}} post-television storyline.
** The other, Non-Season 8/After The Fall comics are up in the air in {{continuity}}, as are all non-Post Chosen novels (those that are Post-Chosen are just non-{{canon}}). Many of the novels are either side stories or {{prequel}}s. The novel ''Go Ask Malice'', for example, is a backstory for Faith that goes up until the episode ''Faith, Hope, Trick''. It's status as {{canon}}, like all of the novels, is unknown, but it does give a backstory for a character with very little and it doesn't violate {{canon}}.
*** The only bit of non-show or non-Season 8 comic that is considered "{{canon}}" came from the fairly short-lived ''Series/BuffyTheVampireSlayer'' role-playing game, and that is Faith's last name; Lehane. This has been confirmed as {{canon}} by its use in the Joss-Whedon-written last issue of the Season 8 comics.
* ''Series/{{Charmed}}'' has novels of both original stories and several based on actual episodes.
* ''Series/{{Firefly}}'' (the original [[TheVerse Verse]]) has a small Expanded Universe in form of comics, RPG supplements and one novelization (of ''Film/{{Serenity}}'').
* ''{{Series/Highlander}}'' has a line of novels that were apparently deemed canon, as their information appears on the offical ''Watcher Chronicles'' CD-Rom released during the series. The comics are a bit more disputed, especially since they were met with mixed reviews.
* ''{{CSI}}'' has a lot of this. Each member of the franchise has a line of novels and comic books associated with it, and then there are the video games.
* Aside from the tie-in novels released with it, ''{{Roswell}}'' has a series of four novels released after the series ended that constitute a sort of print 4th season, although its canon status has not been explicitly confirmed.
* ''TwentyFour'' had several novels and comics usually set before the beginning of the series, mainly using most of the cast from the first season. As a result it mainly featured the characters from early in the show, but some of the later characters were retroactively added in to some of them. There's also a video game set between the show's second and third seasons which is canon, in which the BiggerBad from season 2 returns and is finally taken down by Jack by the end.
[[/folder]]

[[folder:Professional Wrestling]]
* Back in the days before the internet, when {{Kayfabe}} reigned supreme, pro wrestling had the Apter magazines (named for Bill Apter, the most prolific publisher of such), which were something between an Expanded Universe and a MassivelyMultiplayerCrossover of all wrestling federations. While the Apter mags were not endorsed by any of the promotions they covered, and nothing reported in them (from rankings, to wrestler bios, to interviews, to "who would win?" fantasy supercards between promotions, etc.) could be considered {{canon}} to any promotion in particular, the promoters of the time certainly didn't mind the help in exposing their characters and storylines to audiences.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/{{Warhammer 40000}}'' has taken its background and turned it into an Expanded Universe, with material spanning not only the tabletop game but countless novels, graphic novels and {{video game}}s, and the vast and incredibly detailed faux-historical accounts. The same's been done for ''WarhammerFantasy''.
* The BattleTechExpandedUniverse: A long series of sci-fi novels, a pair of VideoGame {{spinoff}}s, and a WesternAnimation series.
* ''TabletopGame/DarkFuture'' gained an expanded background courtesy of [[Literature/DarkFuture a series of novels]] by Creator/KimNewman, who also wrote many of the early ''TabletopGame/{{Warhammer}}''-related fiction.
* {{Eclipse Phase}} encourages fans to produce material for the setting, leading to some extensive universe expansion efforts like the [[http://farcastblog.com Farcast Yearblog]].
[[/folder]]

[[folder:Theme Parks]]
* Having one of these is the reason why ''TheHauntedMansion'' has a page separate from the rest of the DisneyThemeParks, having spawned [[Film/TheHauntedMansion a film]] with another coming soon, a VideoGame, a comic mini-series, and a few books.
* ''Ride/BackToTheFutureTheRide''
[[/folder]]

[[folder:Video Games]]
* [[Franchise/DotHack .hack]] started as [[OneGameForThePriceofTwo four]] [[VideoGame/DotHackR1Games games]], an [[Anime/DotHackSign anime]], a [[Anime/DotHackLiminality 4 episode OVA]], and a [[LightNovel/DotHackAIBuster light novel]]. Now its {{Canon}} alone has 5 novels[[labelnote:*]]Epitaph of Twilight,[[LightNovel/DotHackAIBuster AI Buster]], Zero, Another Birth, and Cell[[/labelnote]], 4 Manga[[labelnote:*]][[Manga/DotHackLegendOfTheTwilight Legend of The Twilight]], Alcor, GnU, and Quantum I(Introduction)[[/labelnote]], 5 games[[labelnote:*]][[VideoGame/DotHackR1Games IMOQ]], [[VideoGame/DotHackGU G.U.]], Link, Versus, and [[SpiritualSuccessor Guilty Dragon]][[/labelnote]], 4 OVA[[labelnote:*]]Intermezzo, Liminality, Returner and Thanatos Report[[/labelnote]], 3 animes[[labelnote:*]][[Anime/DotHackSign SIGN]], Roots, and [[Anime/DotHackQuantum Quantum]][[/labelnote]], 2 movies[[labelnote:*]]Trilogy and Beyond The World[[/labelnote]], and a [[http://www.cc2.co.jp/hack_bullet/ web novel]]. And that's not even mentioning the multitude of uncanon titles, artbooks, and guidebooks.
* ''Franchise/AssassinsCreed'' took its first stab at this with ''ComicBook/AssassinsCreedTheFall'', a comic miniseries. It's canon, too.
* ''{{Halo}}'''s Expanded Universe consists of multiple novels, comics, guidebooks, online exclusives, commercials, live-action features and films, and [[AlternateRealityGame Alternate Reality Games]], along with an [[HaloLegends anime series]]. All of it, whether created directly by staff from Bungie or 343 (the studios behind the games), or by third parties working under their direct control, is not only completely canonical, but is closely integrated with the games. For example, much of ''HaloReach'' will only be understood by people who read the books; this disclaimer even applies to its ''official website''.
** When canon does conflict, policy is that new material overrides old material, and that games and other media created directly by Bungie/343 staff take precedence over everything else.
* Some [[{{Videogame}} games]] like ''StarCraft'', ''VideoGame/{{Diablo}}'' and ''SidMeiersAlphaCentauri '' have a small Expanded Universe, mainly consisting of a few books.
* The WarcraftExpandedUniverse consists of about ten books, one trilogy of manga, two western comic series and two tabletop [=RPGs=].
* The ''Franchise/FinalFantasy'' series has built up an increasingly large Expanded Universe over time, particularly with regard to ''VideoGame/FinalFantasyVII'', which, in addition to its {{prequel}} and {{spinoff}} [[{{Videogame}} games]], has the ''AdventChildren'' movie, two {{anime}} OVA's and several novellas. There's also the ''Legend of the Crystals'' {{anime}} OVA, which takes place 200 years after ''VideoGame/FinalFantasyV'', and the ''Anime/FinalFantasyUnlimited'' {{anime}} series and the ''Anime/FinalFantasyTheSpiritsWithin'' movie (though their relationship to the [[{{Videogame}} games]] is mostly thematic).
* ''Franchise/MassEffect'' and ''Franchise/DragonAge'' have expanded universes. Rather than having books or comics that are simply adaptations, they tell their own coherent story. The novels and comics are often a source of critical plot related information, leading to some events or people being referenced that the gamer may never have heard of. One notable feature is that both novel series are written by the [[{{Videogame}} games]]' lead writers, which is different from the usual operating procedure of Expanded Universe materials. The comics, on the other hand, are written by other people (in both series).
* ''VideoGame/WingCommander'''s Expanded Universe includes ten novels (both adaptations of other material and original stories), multiple [[{{Videogame}} game]] guides, a WesternAnimation series, a CollectibleCardGame, and a movie, all of which officially count towards {{continuity}}.
* ''Franchise/{{Disgaea}}''ís Expanded Universe, the LightNovel/DisgaeaNovels, has currently 15 books. It introduces new family members of the gameís cast and is plays out like traditional ''Disgaea'' crossed with the HaremGenre.
* GameMod ''RedAlert3Paradox'' has an Expanded Universe [[RedAlert3ParadoxExpandedUniverse (TVT page here)]]. It consists of fan-made factions with the goal of building them into their own game mod.
* SuperMarioBros has/had one, having multiple TV shows, the movie, the anime movie, the various comics and the choose your own adventure books in various different 'continuities'. They tend to be even stranger than the original games.
* Surprisingly GearsOfWar has one that includes five novels and a comic book series.
* ''Franchise/{{Pokemon}}''. what do we have here? An anime. Various mangas (one if them is based on the anime instead of games, by the way). Many games with their own universes such as the TCG series and the [[VideoGame/PokemonMysteryDungeon PMD]] series.
* ''Literature/KingsQuest'' had three obscure tie-in novels, the Guidebook to the Land of the Green Isles (doubling as Copy Protection), the Peter Spears guides which are embellished {{novelization}}s of the games with plenty of supplemental material, and the FanSequel and FanRemake games which fill in a lot of holes the old games did not.
* the UrExample for these is VideoGame/{{Zork}}. Hint books, feelies, novels, Choose Your Own Adventure Books, comics, an online role-playing game...Not bad for something that pre-dates graphics!
* ''VideoGame/{{Touhou}}'''s expanded universe exists not only in manga and print works, but also in ZUN's musical [=CD=]s which by themselves introduced two beloved characters to the series' canon.
* ''Franchise/SonicTheHedgehog'', during its first few years, received three comic book lines (including a manga), three TV series, a movie, and a string of children's novels, all of which had its own canon separate from the video games'. Considering that each of them received their devoted followers, albeit of vastly different sizes, it's no wonder that Sonic has the most notorious BrokenBase in history.
* ''VideoGame/{{Runescape}}'' has a trilogy of novels based on it. WordOfGod says that they are considered cannon except for where they contradict the game. The character Kara-Meir showed up in-game at the Battle of Lumbridge. Before that, in the in-game Book of the Gods, the section about the Godless Faction contains a series of messages sent between her and a colleague, showing the story of how they founded the Godless Faction. Because of her important status in the Godless Faction, she is likely to appear again in-game.
* The ''VideoGame/{{Myst}}'' series now stands at three novels, five games, a comic series and an MMO.
* ''VideoGame/MightAndMagic'' has a small expanded universe consisting of three novels, two by Geary Gravel set in an otherwise unvisited world (the original intent was to make it a trilogy leading up to a new Might & Magic game in that world, but when plans for ''Might & Magic VI'' shifted to using the ''Heroes''-introduced world of Enroth, the third book fell through and was cancelled), and one by Mel Odom which has little to do with anything else in the series beyond some shared character-names.
[[/folder]]

[[folder:Web Animation]]
* ''WebAnimation/HomestarRunner'' actually directly references the concept; in the ''Cheat Commandos'' toon "[[http://www.homestarrunner.com/ccdo6.html The Next Epi-Snowed]]", the in-universe writer of the series, A. Chimendez, puts in the AuthorAvatar character "Agent Chimendez" and {{Hand Wave}}s the addition by explaining he's an Expanded Universe character, who appears in novelizations and read-along storybooks.

[[folder:Web Comic]]
* TheBasaltCityChronicles is an expansion of the GeneCatlow WebComic.
* WebComic/ParadoxSpace is an anthology of Homestuck stories set both within and outside of canon.
[[/folder]]

[[folder:Web Original]]
* The film ''Film/RedDawn1984'' got an Expanded Universe in the form of a fan collaboration known as RedDawnPlus20, which is a forum in which posters role play as veterans of the war in the present day, two decades after World War III's conclusion.
[[/folder]]

[[folder:Western Animation]]
* ''{{Transformers}}''. A bunchload of comic books. A number of text stories. A handful of {{video game}}s. And that's not even counting that not all the cartoons are in the same {{continuity}}. Many fans are split over what the primary source really is: the original cartoon is named as such by most, but many others choose the original comic series instead, or the British version thereof, with mixing-and-matching becoming increasingly popular. The term ''{{canon}}'' is hard to apply here: It all happened, but didn't all happen in the same timeline. And with all the other [[{{Continuity}} continuities]] created since, it's become an expanded ''multiverse.''
** ''WesternAnimation/BeastWars'' itself is an example of an Expanded Universe. The TV series, due to the expense of CGI, could only have a limited roster of characters, which meant that most of the [[MerchandiseDriven toyline didn't get to be in it.]] The later IDW ''WesternAnimation/BeastWars'' comics exploited this situation by using all the toy-only characters they could, as well as some from the Japanese-only ''WesternAnimation/BeastWars II'' and ''WesternAnimation/BeastWars Neo'' shows-albeit chronally displaced or on Cybertron, so the TV series and the comics didn't clash.
** The aptly-named ''Universe'' line of toys and comics is built around this, featuring characters from all different timelines and universal streams fighting together in one war. [[MST3KMantra Don't worry about how it happened]], just accept it and enjoy the robo-carnage.
* ''WesternAnimation/AvatarTheLastAirbender'' has [[http://avatar.wikia.com/wiki/List_of_Avatar:_The_Last_Airbender_comics a number of comics]] that chronicle the adventures of the Gaang that are not shown in the TV series.
** Also there are two trilogies of graphic novels that show the events that directly follow the finale and lead into WesternAnimation/TheLegendOfKorra know as ComicBook/AvatarTheLastAirbenderThePromise and Comicbook/AvatarTheLastAirbenderTheSearch.
* ''{{Daria}}'' has one, including the show, its two [[AllThereInTheManual published manuals]], its parent show ''BeavisAndButthead'' and any of its spin-offs. However, the ''term'' "Expanded Universe" usually refers to a group of interconnected {{Fan Verse}}s that most serious fans know, with its own set of {{Original Character}}s who appear in multiple creators' fanworks.
* ''WesternAnimation/LooneyTunes'' has had comic books, movies, picture books, TV specials, spinoffs, and story [=CDs=] galore.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has a steadily growing one with the [[ComicBook/MyLittlePonyFriendshipIsMagicIDW comic book series]] plus assorted chapter books and a series manual.
* The ''WesternAnimation/KungFuPanda'' movies have one in the form of Direct-To-Video specials and [[WesternAnimation/KungFuPandaLegendsOfAwesomeness a television series]].
** ''WesternAnimation/HowToTrainYourDragon'', another DreamWorks franchise, also has a [[WesternAnimation/DragonsRidersOfBerk television series]].
* ''WesternAnimation/TheSimpsons'' has at least three comic books (One is like the show, one is an annual horror anthology done by multiple writers and artists, and one is a SpinOff focusing on Bart Simpson).
* ''WesternAnimation/{{Futurama}}'' has a comic book series and four DTV movies, all of which served as a continuation of the television series before it was {{Uncanceled}}. The comic book is still ongoing though.
* ''WesternAnimation/AdventureTime'' has recently gotten three comic book series: One that's like the show, another that's a SpinOff focusing on Marceline and Princess Bubblegum, and a miniseries based around the GenderFlip episode.
* After TheLionKing film became extremely popular, a series of books known as "The Six New Adventures" was released as well as a boatload of comics. These introduced dozens of new characters and explained mysteries such as Scar's birth name. However, the printed works are also inconsistent with the movies and each other, leading to much of the [[{{headscratchers}} headscratching]] and {{wild mass guessing}} within the fandom.
