Let's say you write a book. The readers love it, the critics love it, and everyone wants to see a movie of it. But when [[TheFilmOfTheBook the movie]] finally comes out, it's a major letdown. Or perhaps it works out fine, but a few years later, people still love the book yet [[FleetingDemographicRule don't seem to remember]] that the movie ever happened.

Not wanting to waste a good story, the studio makes up its mind to try again.

And again, and again, and again.

Anyway, this is all about stuff that doesn't merely get multiple or long-running adaptations, but actually has a whole bunch of [[AlternateContinuity Alternate Continuities]] (preferably at least three within the same medium) as a result. Perhaps in some cases, the audience will "win" and one adaptation will [[AudienceColoringAdaptation cement itself in the public memory for all time]].... Perhaps the studios will keep playing anyway. In most cases, it seems they just can't seem to get it right, but that's always a matter of opinion.

This is ''[[JustForFun/IThoughtItMeant not]]'' about works that simply have [[LongRunners lots of sequels]] or vast {{expanded universe}}s within the same continuity; in other words, ''Franchise/StarWars'' and ''Franchise/StarTrek'' are not examples. ''Star Wars'' almost could count as an example for the sheer number of times the individual storyline of each film has been adapted. ''Film/ANewHope'', for example, has two {{novelization}}s, three comic strip versions, a {{manga}} version, a RadioDrama version, some journals written from the POV of the characters, is retold in part of the ''[[VideoGame/LegoAdaptationGame LEGO Star Wars]]'' video games, and a version written InTheStyleOf Creator/WilliamShakespeare. However, all but the Lego and Shakespeare versions [[RetCon supposedly]] take place in the same continuity.

!!Examples (listed by the original work):


[[folder: Anime & Manga]]
* ''Manga/MahouSenseiNegima'' probably gets the award for the most thorough invocation of this trope in the shortest amount of time. At present, there has been the original manga, two broadcast {{Animated Adaptation}}s, a LiveActionAdaptation, a few {{OVA}}s, ''a second manga released parallel to the first'', a SpinoffBabies series, and a movie covering an alternate end to the manga. Only the {{OVA}}s and the first manga seem to occupy the same continuity. At this rate, by the year 2020 there'll be eight or nine movies, a couple of [[FilmNoir noir]] or [[TheWestern western]]-themed animes, ''and an opera''.
* ''{{Manga/Appleseed}}'' (manga, 1980s anime OVA, recent CGI movies, and now a new CGI series)
* ''Franchise/GhostInTheShell'' ([[Manga/GhostInTheShell manga]], movies ([[Anime/GhostInTheShell animated a]][[Film/GhostInTheShell nd live action]]), ''[[Anime/GhostInTheShellStandAloneComplex Stand-Alone Complex]]'' anime TV series, ''[[Anime/GhostInTheShellArise Arise]]'' OVA series).
* ''Anime/NeonGenesisEvangelion'' is famous for this. The original anime and manga series are set in similar, but distinct continuities. Then after that you get into the ''Raising Project'' games, the ''[[Manga/ShinjiIkariRaisingProject Raising Project]]'', ''Girlfriend of Steel''/''Iron Maiden'', ''Anime/RebuildOfEvangelion'', ''[[Manga/NeonGenesisEvangelionAngelicDays Angelic Days]]'', ''[[Manga/NeonGenesisEvangelionCampusApocalypse Campus Apocalypse]]'', [[SuperDeformed Eva Pucchi]], the reportedly-still-under-development live-action movie... oh, and of course ''End of Evangelion'' as possibly alternative ending.
* ''Manga/BoysOverFlowers'' has no less than three official live action series adaptations (one in China, one in Tokyo, and one in Korea), plus a second, unofficial Chinese adaption, an anime, and the original manga.
* ''Anime/{{Robotech}}'' spun off of ''Anime/SuperDimensionFortressMacross'', merging it with ''Anime/SuperDimensionCavalrySouthernCross'' and ''Anime/GenesisClimberMospeada''. Then there were novelizations and RPG and comic adaptations, none of which quite perfectly matched with the others. There were spin-off novels and comics, as well. Then there was an abortive 3-episode sequel series, which was again adapted and continued three different ways in comics, novels, and game. Then there was the sequel ''WesternAnimation/RobotechTheShadowChronicles''.
* The Saiyan, Namek, and, to a lesser extent, Androids/Cell arcs in ''Anime/DragonBallZ'' might count, as almost every game released ever since they started back in ''1988'' covers one or several of them and quite a few cover those and ''just'' those. The only exceptions are either sequels to them or the ones that cover Kid Goku stories (either ''Manga/DragonBall'' or ''Anime/DragonBallGT''), which are very few. They're also the first arcs to be adapted on ''Anime/DragonBallKai'', with a long gap before the Buu Saga was confirmed.
* ''Anime/CuteyHoney'' has five animated incarnations, three live action incarnations, and five manga incarnations. Try asking a fan of the show where Honey's powers come from. Heck, try asking them whether or not she's human; the answer changes in just about every version. You'd think they'd run out of answers to a yes/no question eventually, but no...
* ''Anime/PuellaMagiMadokaMagica''. The original TV anime, a manga (plus two SpinOff manga), a novelization, a PSP game, and now a pair of {{Compilation Movie}}s. And all of this was announced in less than a year after it started, so there's still the possibility of more still being created.
* ''Anime/CodeGeass'' has only one full-length anime, but there are ''four'' separate and [[AlternateContinuity completely different]] manga adaptations as well as three games based on it. As of early 2012, two spinoff [=OVAs=], a film version of the original series, and yet another alternate-viewpoint manga are planned (the original anime came out in 2006).
* ''Manga/HimitsuNoAkkoChan'' has three anime and a LiveActionAdaptation.
* ''Franchise/SailorMoon'' has, in rough chronological order: the ''Sailor V'' manga, the actual ''Sailor Moon'' manga, the original anime adaptation in the '90s, the original set of musicals from the '90s (which lasted until 2005), a live-action adaptation in 2004, a bucketload of video game adaptations/spin-offs/what-have-you (from typical '90s beat-em-ups and arcade games to an official smartphone game), a ''new'' batch of musicals unrelated to the first in pretty much every way, and the 2014 anime. This is discounting the ''attempted'' American cartoon-live-action hybrid thing in the '90s, and -- if one wants to consider them different adaptations because of how [[{{Macekre}} different]] they are -- various dubs from around the world. Also, a weird set of American novelizations from the '90s, and who knows what other obscure (but official/licensed) adaptations from other corners of the world. And note that every adaptation is ''very'' different from the rest.
* The ''Anime/{{Pokemon}}'' anime has two different multi-volume manga (''Manga/TheElectricTaleOfPikachu'' being the first and ''Satoshi to Pikachu'' being the second), a [[Theatre/PokemonLive theatrical musical adaptation]], multiple [[Anime/{{Pokemon}} theatrical films]], numerous manga adaptations of said films, various {{Tie In Novel}}s, several {{novelization}}s (the most famous being ''LightNovel/PocketMonstersTheAnimation''), and several radio dramas.
* ''Manga/GeGeGeNoKitaro'' has had six different anime series across various decades, one DarkerAndEdgier anime, and even a few live action versions.

[[folder:Comic Books]]
* ''Franchise/TeenageMutantNinjaTurtles''. Starting as a comic book series it has expanded to four cartoon series ([[WesternAnimation/TeenageMutantninjaTurtles1987 one only loosely based on the original comics]]; [[WesternAnimation/TeenageMutantNinjaTurtles2003 another that started out a direct adaptation but later diverged]]; [[WesternAnimation/TeenageMutantNinjaTurtles2012 the third somewhere in between]]), two anime [[OriginalVideoAnimation OVA's]], two live-action specials (song themed), [[Series/NinjaTurtlesTheNextMutation a live-action series]], three other comic book series, a daily strip, [[Film/TeenageMutantNinjaTurtles five live-action films]], a CGI film, several kids' books, novels, magazines, games and crossovers, and heaven know how many toys and merchandise (including a set of "automutating" TMNT ''transformers'' of all things).
* ''Franchise/{{Hellboy}}'', despite being a relatively young property owned by one guy, has at least three continuities, including the comics, the animated series, and the live-action series. There are also at least two "little Hellboy" spinoffs.
* Of all the superhero properties, ComicBook/SpiderMan has been rebooted the most frequently in recent years: his appearance in ''Film/CaptainAmericaCivilWar'' and subsequent solo film ''Film/SpiderManHomecoming'' has marked the [[Film/SpiderMan third]] [[Film/TheAmazingSpiderMan iteration]] of the character in just over ten years.
* The Franchise/{{Batman}} mythos seems to be falling prey to this. Batman was already one of the most commonly-adapted character, with three adaptations/series in the last ten years (''Film/TheDarkKnightTrilogy'', the Franchise/DCExtendedUniverse, and ''WesternAnimation/TheLegoBatmanMovie''). But then there's the ''VideoGame/BatmanArkhamSeries'', ''Film/SuicideSquad'' (which is part of the above mentioned [=DCEU=]), an upcoming unrelated Joker film directed by Creator/MartinScorsese, and ''Series/{{Gotham}}'', not to mention [[Series/{{Batman}} the classic Adam West live-action series]] and at least five animated series (at least seven if you count ''Justice League'' and ''Justice League Unlimited'' as separate from both each other and ''Batman: The Animated Series'').
* ''ComicBook/ArchieComics'' has had one [[Film/ArchieToRiverdaleAndBackAgain made-for-tv film]], one [[Series/{{Riverdale}} live action show]], numerous animated adaptations [[WesternAnimation/TheArchieShow dating back to the 1960s]], and at least one radio show.

[[folder:Comic Strips]]
* ''ComicStrip/{{Peanuts}}'' inspired many animated films and television specials, [[https://en.wikipedia.org/wiki/Peanuts_filmography two stage plays and some video games]], a Creator/BoomStudios comic book, and [[WesternAnimation/ThePeanutsMovie feature film]]. Not to mention lots of merchandise.
* Likewise, ''ComicStrip/{{Garfield}}'' has lots of television specials, two cartoons (''WesternAnimation/GarfieldAndFriends'' and ''WesternAnimation/TheGarfieldShow''), [[Film/{{Garfield}} two live-action movies]], a few straight-to-video animated movies, many video games, a Creator/BoomStudios comic book... and some different approaches, such as the book/special ''Comicbook/GarfieldHis9Lives'' and the [[https://en.wikipedia.org/wiki/Pet_Force Pet Force]] series.
* ''ComicStrip/LittleOrphanAnnie'' has had several film adaptations, a fairly popular radio series, and, of course, [[Theatre/{{Annie}} a hit musical]] which spawned three of its own film adaptations as well as sequels both on screen and in the theatre.

* Literature/SherlockHolmes definitely deserves to be mentioned separately, having been played by [[http://en.wikipedia.org/wiki/Adaptations_of_Sherlock_Holmes over 75 different actors in 211 films]].
* Literature/StarshipTroopers has spawned a [[Anime/StarshipTroopers 1988 anime miniseries]],three strategy tabletop games,a [[Film/StarshipTroopers 1997 live-action film with two sequels]], a [[WesternAnimation/RoughnecksStarshipTroopersChronicles CGI television series]], a [[Film/StarshipTroopersInvasion CGI film]], a [[VideoGame/StarshipTroopers video game]], and a live-action Hollywood reboot on the way.
* ''Literature/AChristmasCarol'': Has been made into no less then 40 films, including animated versions, made-for-tv movies, musicals, silent films, and a [[Series/TheMuppetShow Muppet]] [[Film/TheMuppetChristmasCarol version]]. There are also many stage adaptations, and at least one ballet version! And that's not even getting into the YetAnotherChristmasCarol trope. Best exemplified by ''WebVideo/TwelveHundredGhosts'', which is 400 adaptations of the work in one video and ''still'' isn't all of them.
* ''Literature/IAmLegend'' has had three movies since it was written in the 1950s, and all of them take the plot and characters in different directions.
* ''Franchise/TheHitchhikersGuideToTheGalaxy'' was originally a [[Radio/TheHitchhikersGuideToTheGalaxy 6-expanded-to-12-episode radio comedy]], then a series of [[Literature/TheHitchhikersGuideToTheGalaxy novels]] based on it, an [[VideoGame/TheHitchhikersGuideToTheGalaxy adventure game]], a [[Series/TheHitchhikersGuideToTheGalaxy TV series]], a sequel radio comedy series, and [[Film/TheHitchhikersGuideToTheGalaxy a movie]]. Each one of them considerably different from the others. Unusually, this was intentional on the part of Creator/DouglasAdams (who was the primary or sole writer of the radio, TV and novel versions).
* ''Literature/TheWonderfulWizardOfOz'' has [[Literature/LandOfOz 39 books]], a series of silent short films, the [[Film/TheWizardOfOz classic musical adaptation]] which itself has [[Film/ReturnToOz a sequel]], [[Film/OzTheGreatAndPowerful a prequel]] and an Creator/AndrewLloydWebber-helmed stage version, a [[Series/TheMuppetShow Muppet]] version, an [[Anime/TheWonderfulWizardOfOz anime series]], stage plays including [[Theatre/TheWiz a pop music-driven reimagining with an all-black cast]] which itself got [[Film/TheWiz a film adaptation]] helmed by [[Creator/SidneyLumet the unlikeliest of directors]], [[Series/TinMan a modernized TV series]], an [[Literature/{{Wicked}} alternate interpretation of Oz and the villain]] (which in itself has [[Theatre/{{Wicked}} a musical]] and an upcoming film), cartoons, and [[Literature/TalesOfTheMagicLand a Russian translation that diverges considerably as it goes on]].
* ''Literature/AlicesAdventuresInWonderland'' has 16 different film adaptations, including two by [[Disney/AliceInWonderland Disney]], a DarkerAndEdgier [[VideoGame/AmericanMcGeesAlice video game]], a [[Series/{{Alice|2009}} TV miniseries]], an anime remembered in many places that aren't the States, a re-imagining book series, Sci Fi...
* ''[[Literature/TheBountyTrilogy Mutiny on the Bounty]]'': At least three film versions, a few novels, probably a play or two.
* ''Literature/CharlieAndTheChocolateFactory'' was published in 1964, and by its 50th anniversary in 2014 had already yielded [[Literature/CharlieAndTheGreatGlassElevator one sequel]], several audiobook versions and a pop-up book abridgement, and the following adaptations, all of which are distinct takes on the story:
** Two movie versions ([[Film/WillyWonkaAndTheChocolateFactory 1971]] and [[Film/CharlieAndTheChocolateFactory 2005]])
** A stage play in TheSeventies
** A touring stage musical in TheEighties
** A VideoGame/ZXSpectrum video game
** A BBC radio play
** A ride at England's Alton Towers
** [[Theatre/TheGoldenTicket An opera]]
** An island in the online game ''VideoGame/{{Poptropica}}''
** A 2013 [[Theatre/CharlieAndTheChocolateFactory West End stage musical]] (which includes {{Internal Homage}}s to and one song from the film adaptations but is '''not''' a ScreenToStageAdaptation at all)
** The two film adaptations have each been incorporated into other media: The 1971 film was greenlit to launch a still-extant [[{{Defictionalization}} defictionalized]] candy brand, its songs appeared in a 2005 stage musical (''Roald Dahl's Willy Wonka'') that otherwise stuck closer to the novel, and in 2013 it was the basis for licensed casino slot machines. The 2005 film was the basis for several tie-in video games.
* Every decade or two, Creator/TheBBC goes on a Creator/JaneAusten kick and remakes most of her most famous works (usually ''Literature/PrideAndPrejudice'', ''Literature/SenseAndSensibility'', ''{{Literature/Persuasion}}'', and ''{{Literature/Emma}}'') as miniseries. Each of those four novels has three or four BBC adaptations as well as several movie adaptations. Her works also frequently receive the SettingUpdate treatment (''Literature/BridgetJones'' books and movies, ''Film/{{Clueless}}'' or ''WebVideo/TheLizzieBennetDiaries'').
* ''Literature/AndThenThereWereNone'' by Creator/AgathaChristie has had multiple film adaptations. The novel's plot has even [[TenLittleMurderVictims become a trope in its own right]].
* There have been several adaptations of most of Creator/HGWells' books, especially ''Literature/TheWarOfTheWorlds'' and ''Literature/TheTimeMachine''. The former is especially prone to getting a SettingUpdate about once a generation.
* ''Literature/LastOfTheMohicans'' by James Fenimore Cooper, in addition to being part of a 5-book series, has itself been adapted to film at least five times, with the last (most famous) one being a remake of a previous screenplay; a graphic adaptation by Marvel, and inspired a series of classical oil paintings when it first came out in 1827, along with having some local landmarks named after the characters.
* ''Franchise/{{Zorro}}'' has been adapted many times.
* ''Literature/ThePhantomOfTheOpera'' [[OlderThanTheyThink began as a novel by Gaston Leroux]]. Has since been adapted into goodness knows how many movies, at least six stage musicals (seven if you count ''Theatre/LoveNeverDies'', which is a sequel to [[Theatre/ThePhantomOfTheOpera the most famous musical version]]), quite a few additional novels and numerous spoofs/reworkings on TV. Not to mention songs about it by Music/IronMaiden and Music/IcedEarth.
* ''Literature/LittleWomen'' has been made into several stage plays, movies, TV miniseries, anime, an opera and a Broadway musical.
* ''[[TheKingAndI Anna And The King Of Siam]]'' has given us one Broadway musical, four movies (two of which are based on the musical), and a short-lived sitcom.
* ''Literature/TheJungleBook'' has had so many film and TV adaptations, both live action and animated, that Creator/RudyardKipling's version is probably the ''least'' well-known.
* Similarly, ''Franchise/{{Tarzan}}'' has had so many movies, TV shows and cartoons based on it that the original books by Creator/EdgarRiceBurroughs are obscure by comparison.
* ''TheRing'' has been made into a film four times - twice in Japan (once as a semi-pornographic TV movie!), once in Korea (as ''The Ring Virus''), and once in America. There have also been two Japanese TV series, three Japanese sequels, and one American sequel (directed, oddly enough, by the same guy that directed the original Japanese film). It was also adapted into a manga.
* ''Literature/TheThreeMusketeers'' by Creator/AlexandreDumas. A quick search on Website/IMDb returned 48 results. [[Franchise/TheThreeMusketeers This page]] has a very incomplete list of adaptations.
** And one of the book's sequels, ''The Vicomte de Bragelonne'', has been adapted to film many times as ''Film/TheManInTheIronMask'' (the article covers only the 1998 Creator/LeonardoDiCaprio version).
** Creator/DouglasFairbanks adapted both books, the first as ''The Three Musketeers'' in 1921 and the second as ''Film/TheIronMask'' in 1929.
* ''Literature/TheCountOfMonteCristo'', also by Dumas, has also had a ton of adaptations. [[Film/TheCountOfMonteCristo The film]] with Creator/JimCaviezel is only one of many.
* ''Literature/{{Dracula}}''. The fact he has his own page on this very website should be proof enough of how much often he tends to appear in mediums of every shape and form. Most tend to adapt more from [[Film/{{Dracula 1931}} the famous 1931 Universal film]] then the original novel by Creator/BramStoker.
* ''Literature/{{Frankenstein}}'' by Creator/MaryShelley has spawned [[Franchise/{{Frankenstein}} many adaptations]]. UsefulNotes/ThomasEdison produced the [[Film/{{Frankenstein 1910}} first movie]] in 1910! Not to mention many SpiritualSuccessor stories using its ArtificialHuman plot.
* ''Literature/TheGirlWhoLeaptThroughTime'' one novel that received: three television series, four live-action films, one animated film, and two manga adaptations.
* ''Literature/LesMiserables'' has over 60 adaptations for radio, anime, theatre, TV, film (the latest being a big-screen adaptation of the stage musical) and [[TheLastOfTheseIsNotLikeTheOthers at least one fighting game]]. [[http://tig.wikia.com/wiki/Arm_Joe Yep.]]
* ''Literature/TreasureIsland'' has many film adaptations, including an {{Anime}}, a [[Film/MuppetTreasureIsland muppet version]] and a couple of versions [[RecycledInSpace set in space]]. There are also a number of television series, as well as theater, radio, video games and music.
* ''Literature/JaneEyre'' by Creator/CharlotteBronte gets adapted in film or miniseries or on stage a lot, and not only in English-speaking countries. Check the work's [[Film/JaneEyre film page]].
* All ''Literature/JamesBond'' books and almost all short stories had film adaptations (twice in the cases of ''Literature/CasinoRoyale'' and ''Literature/{{Thunderball}}'', and the former was adapted for television as well), and many were also translated into comics, radio plays, and the occasional video game - though in most places, [[AdaptationDisplacement the film series is the one serving as inspiration]].
* ''Literature/TolkiensLegendarium'' has been made into two three-part film series, three full-length animated films, several radio plays, and many video games and tabletop games.
* Literature/{{Heidi}} has received many film adaptations, as well as an [[Anime/HeidiGirlOfTheAlps anime series]].
* The ''Literature/TheDivineComedy'' has been adapted hundreds of times (although most of the adaptations focus on the ''Inferno''), including at least twenty-four films, four operas, video games for the UsefulNotes/Commodore64 and UsefulNotes/Xbox360, and even a few comic book issues during certain runs of the ''ComicBook/DisneyMouseAndDuckComics'' and the ''ComicBook/XMen''.
* ''Literature/FreakyFriday'' became a Creator/{{Disney}} [[Film/FreakyFriday1976 movie]] in 1976. Then, from TheNineties until at least TheNewTens, Disney produced at ''least'' one new version of the story per decade, for either TV, the big screen, or the stage.

[[folder:Myths & Religion]]
* Literature/TheBible has been adapted literally hundreds of times, covering just about every medium there is, which can be expected, since it's the religious text for the world's largest religion. Among the most commonly adapted Bible stories:
** The Noah's arc story from the Literature/BookOfGenesis.
** The entirety of the Literature/BookOfExodus, especially the liberation of the Jews by God through Moses the Prophet.
** The accounts of UsefulNotes/{{Jesus}}'s life, death, and Resurrection from Literature/TheFourGospels.
* The Myth/KingArthur mythos, of course. Every few generations needs a new adaptation of the old stories, starting with ''Literature/LeMorteDarthur'' by Malory and moving on to [[Literature/IdyllsOfTheKing Tennyson]], [[Literature/TheOnceAndFutureKing T. H. White]], [[Literature/KnightLife Peter David]]...
* Myth/RobinHood also has a ridiculous amount of adaptations, including TV shows, movies, books, video games, and that's not even getting into "[[RecycledInSpace Modern Robin Hood]]" territory.
* Many stories from Myth/ClassicalMythology are a popular choice for all kinds of adaptions, be it the ''Literature/TheIliad'' and ''Literature/TheOdyssey'', the adventures of Herakles, the journey of Jason and the Argonauts, the quest of Perseus...

* ''Theatre/{{Carmen}}'' is known for its frequent adaptations. Although most of them are derived from one particular adaptation, Bizet's opera, with the original novella falling victim to {{Adaptation Displacement}}.
* Stage versions of Creator/WilliamShakespeare's plays don't count as adaptations, but the many straight up stage-to-screen adaptions, and the inspiration for new scripts, easily number into the hundreds. The BBC appears to feel a need to produce a definitive TV version of the compleat Shakespeare folio, approximately once every fifteen years or so.
* ''Theatre/{{Chess}}'' started out as a ConceptAlbum in 1984. It was adapted into a stage musical for the first time in 1986, but a mixture of ExecutiveMeddling and attempts to cope with TheGreatPoliticsMessUp meant that for some time, every time the show popped up in a new location it was practically a new musical, [[AdaptationDecay sometimes venturing pretty far from the album's storyline]]. Even a couple decades later [[BrokenBase there's no consensus on which staged version did it right]] if any did at all, so new variations of the story continue to pop up.

* ''Franchise/{{Transformers}}'' has to take some kind of a record. It has -- let's see now -- several lines of toys, the original American cartoon ''WesternAnimation/TheTransformers'', several successive anime that continued from where the American one left off (''Anime/TransformersHeadmasters'', ''Anime/TransformersSuperGodMasterforce'', ''Anime/TransformersVictory'', ''Manga/TransformersZone''), five or six different comic book series (''ComicBook/TheTransformersAllHailMegatron'', ''ComicBook/TheTransformersIDW''), spanning all the different TV show and toy eras (''ComicBook/TransformersGenerationOne'', ''ComicBook/TheTransformersLastStandOfTheWreckers''), American and British (''Comicbook/TheTransformers''), ''WesternAnimation/BeastWars'', the Japanese spinoffs (''Anime/BeastWarsII'', ''Anime/BeastWarsNeo''), ''WesternAnimation/BeastMachines'', [[Anime/UnicronTrilogy several more Transformers anime]] set in {{Alternate Universe}}s that were dubbed for American consumption after Hasbro succumbed to fan backlash over ''Beast Machines'' (they originally intended a sequel to that named ''ComicBook/TransformersTransTech''), [[Film/{{Transformers}} the live-action films]] which occupy their own AU and possess their own novel and comic adaptations, [[WesternAnimation/TransformersAnimated two more]] [[WesternAnimation/TransformersPrime American cartoons]] which are also their own universes, and a Japanese toy and manga series called ''Kiss Players'' which involved InterspeciesRomance on the Autobot side and ''[[AlienLunch vorarephilia]]'' on the Decepticon side.\\\
In short: Look at [[http://tfwiki.net/wiki/Series this full listing of everything]] and try to not go too cross-eyed. And that's not even counting the ''{{Diaclone}}'' and ''MicroMan'' Japanese lines whose overstocks and remainders were sold to Hasbro to become the original Transformers toys.
* Likewise, sister franchise ''Franchise/{{GI Joe}}'' (both are by Hasbro, and earn the occasional CrossOver). Ever since the second generation in 1982, ''G.I. Joe: A Real American Hero'', was accompanied by a comic book and an animated series, the franchise has since earned plenty of other comics and cartoons, [[Film/GIJoeTheRiseOfCobra two]] [[Film/GIJoeRetaliation movies]], and the occasional game.

[[folder:Video Games]]
* The ''Franchise/{{Lunar}}'' series keeps making new versions of the same games. The first game in the series was first released on Sega CD and later reworked for the Saturn and UsefulNotes/PlayStation, followed by a GBA remake, followed by a [=PSP=] remake. The [=PlayStation=] version is generally best-known (and pretty {{troperiffic}} compared to the Sega CD original). Plus, most of the other games in the series have their own remakes, except just one a piece instead of three. And that's without getting into the novelizations, manga and audio dramas.
* ''Franchise/SuperMarioBros''. Less so now, but as well as the games there are the spinoff games in about ten series, three cartoon shows, about four anime films, the live action film, various manga series, three series of American comic books, German comics in Club Nintendo, the Ice Capades, books, and random series that have very little to do with anything (''Mario All Stars'' cartoon series consisting of recycled stuff from the first three, King Koopa's Kool Kartoons).
* ''Franchise/SonicTheHedgehog'' has an [[Anime/SonicX anime]], [[ComicBook/SonicX an adaptation of that anime]], an [[Anime/SonicTheHedgehogTheMovie OVA]], [[WesternAnimation/SonicSatAM two American animated series]] [[WesternAnimation/AdventuresOfSonicTheHedgehog that were launched simultaneously]], a [[WesternAnimation/SonicUnderground later American animated series]], [[WesternAnimation/SonicBoom another American animated series over a decade after those three]], a [[Film/SonicTheHedgehog2019 theatrical movie]], a [[ComicBook/ArchieComicsSonicTheHedgehog U.S. comic series]], [[ComicBook/SonicTheHedgehogIDW a later U.S. comic series]], a [[ComicBook/SonicTheComic UK comic]], several {{manga}}, and numerous '90s book adaptations not based off any comic. And we haven't even mentioned the spinoff games.
* ''Franchise/{{Pokemon}}'': There's the original games, the spinoff titles (which itself has a load of diverse examples, ranging from [[VideoGame/PokemonSnap rail shooter where you take photographs]] to a [[VideoGame/DetectivePikachu a visual novel that stars a talking Pikachu]]), the [[VideoGameRemake remakes]] of the older games (which both [[AdaptationExpansion expand upon]] the originals and [[CanonDiscontinuity retcon certain aspects of them]]), the [[Anime/{{Pokemon}} anime]], a collectible card game, at least three manga adaptations of the anime and several movie-specific ones, various adaptations of the games, over 40+ other manga which seem to do their own thing separate of other continuities. And that's just the beginning.

[[folder:Western Animation]]
* ''Franchise/ScoobyDoo'' spawned numerous {{animated series}}, including a SpinoffBabies series, as well as many animated movies (''Reluctant Werewolf'' and ''The Ghoul School''), several live action movies, more animated movies (''Zombie Island'', ''The Alien Invaders'', etc.), another animated series with a modern update, and many more animated movies based off of that series.
