->'''Conan''': You have no memory of making ''Film/TheStarWarsHolidaySpecial''?\\
'''Creator/HarrisonFord''': No memory.\\
'''Conan''': So it doesn't exist.
-->--''Late Night with ConanOBrien'', [[http://www.dump.com/conanford/ 2006 interview]]

When an element of canon is removed from canon of a work by those who write the work.

There are numerous reasons why this can happen. It can be an uncomfortable case of OldShame, double standards, MisaimedFandom or UnfortunateImplications for the writers. It can also happen when FanonDiscontinuity is so vehement that the writers end up agreeing and rewrite the canon. Sometimes it's just a moment or piece of writing viewed as stupid, unpopular, or simply not making sense within that universe. A {{retcon}} big enough, or duelling writers that are ArmedWithCanon can cause elements of a work, like characters, events, or episodes to be turfed out of the canon.

Sometimes the discontinuity is more subtle, such as a single line of dialogue or the specifics of an event. Besides those things, everything else is in canon. When that happens, they're treating it in BroadStrokes. Note that this trope has to do with the ''creators'' putting something out of continuity. Obviously, this is one of the meta-causes of AlternateUniverse.

See also ContinuityReboot, AlternativeContinuity, BroadStrokes, DisownedAdaptation. OldShame works usually get this treatment. The opposite of RetCanon and its descendant tropes. See CuttingOffTheBranches for when all but one ending of a MultipleEndings game becomes canon discontinuity. When fans do this, it is FanonDiscontinuity. If the writers lampshade a discontinuity, either canonical or just something the fans want to be discontinued, then that's DiscontinuityNod. See also the OrwellianRetcon, which may overlap with this.

Not to be confused with ExiledFromContinuity, when it's a ''character'' or a specific element or elements of a universe that are declared off limits for use, be it in-universe or in another version of that universe, for legal reasons or otherwise (although whether they are simply made non-canon or technically still exist, but can't be used depends on the situation).



[[folder:Multiple Media]]
* The ''Franchise/StarWarsExpandedUniverse'' has always existed in stages of canon, with works in higher levels overriding lower levels, and the six films overriding everything. But after acquiring Lucasfilm in 2012, Disney decided to officially drop the lot of it, as seen [[http://starwars.com/news/the-legendary-star-wars-expanded-universe-turns-a-new-page.html here]], with the business end formally coming down on April 25th, 2014. The Disney-Lucasfilm group created a dedicated Story Team to ensure ''everything'' produced under the new regime, starting with ''WesternAnimation/StarWarsRebels'', is iron-clad and wholly consistent canon, but this necessitates the formal axing and cessation of the old EU and content for it. All of the old EU material is now reclassified as "Legends" that may or may not have happened, and sold as such.

[[folder:Anime & Manga]]
* The last hundred or so pages of ''[[Manga/{{Gunnm}} Battle Angel Alita]]'' are ignored by the renewed ''Battle Angel Alita: Last Order''; originally intended as an [[RecursiveAdaptation adaptation of the last level of the game of the comic]], it has spiraled into a second story longer than the original that is still ongoing. Note that in this case, the original ending was an effort to avoid AuthorExistenceFailure. After he got better instead, he decided to do it right.
* ''Anime/NadiaTheSecretOfBlueWater''[='s=] director Creator/HideakiAnno created a compilation of the series called "The Nautilus Story", with the conspicuous absence of 11 infamously poor quality filler episodes nicknamed the "Island Arc". All that remains of these filler episodes are twelve minutes, using mostly clips from episodes 23, 28, 30, and 31. A brief shot from episode 32 where the companions look down from the ''Gratan'' substitutes the title card for episode 35.
* The ''Anime/DragonBallZ'' movie ''Battle of the Gods'' effectively retcons ''Anime/DragonBallGT'' by having [[spoiler:Pilaf and his crew be children again as a result of a poorly worded wish on the Dragon Balls]]. Akira Toriyama himself called ''GT'' a "wonderful side story", which is [[DamnedByFaintPraise a polite way of saying it didn't happen]], long before ''Battle of Gods'' was even imagined.
* The animated version of ''Manga/TsubasaReservoirChronicle'' contains a discontinuity with the "Tokyo Revelations" [=OAV=]s ignoring the last filler arc from the broadcast series and picking up right after the escape from the Rekort library.
* ''Anime/MacrossII'' was officially shunted off into its own private universe. Aspects of the original ''Anime/SuperDimensionFortressMacross'' TV series and the movie ''[[Anime/MacrossDoYouRememberLove Do You Remember Love]]'' are taken in BroadStrokes in later ''Macross'' series. A good portion of this stems from how ''Macross II'' [[GodDoesNotOwnThisWorld was not a Studio Nue production]] -- Bandai wanted something [[MilestoneCelebration for a tenth-anniversary celebration in 1992]], and when it seemed that Shoji Kawamori's cooperation was not forthcoming, came up with the story themselves. Of the original production staff, only Haruhiko Mikimoto actually worked on ''Macross II''.
* Nothing from the Sun Wukong arc of ''Shamo'' has been mentioned once in subsequent chapters. The arc that followed it was a flashback arc that followed a different character, and when the series finally came back to protagonist Ryo Narushima he had become a washed-up prize fighter, as opposed to the near demi-god he was at the end of the Sun Wukong arc.
* The second ''Anime/DigimonTamers'' movie is mostly about a Digimon attacking on [[BrokenBird Rika's]] birthday and mind-controlling her with a song she used to sing with her father. It also seemed to latch on to the idea planted in the final episode that the Tamers could use the portal Takato found in Guilmon's house to reunite with their partners. It was written and produced without the input of the head writers, however, and a CD drama released later reveals that the kids had yet to reunite with their partners even a year later, and revolved around them sending messages to the Digital World that their partners might stumble upon one day. (One of the writers speaks highly of the movie on his website, however, and the drama has a scene of Rika humming the song from the movie.)
* ''Franchise/{{Gundam}}'':
** ''Gaia Gear'' is a novel written by franchise creator Creator/YoshiyukiTomino, set 110 years after ''[[Anime/MobileSuitGundamCharsCounterattack Char's Counterattack]]'' and focusing on a literal CharClone. The later ''[[Anime/MobileSuitGundamF91 Gundam F91]]'' and ''[[Anime/MobileSuitVictoryGundam Victory Gundam]]'', also written by Tomino, push ''Gaia Gear'' into discontinuity by contradicting elements of its backstory. On top of that, we have Tomino's ''Reconqista in G'' (AKA ''G-Reko''), which purportedly takes place in the future of the Universal Century timeline.
** ''Film/GSaviour'' is in a strange place with regards to continuity. Sunrise has never said it's non-canon, but have also admitted that they do not like to talk about it and generally pretend the movie doesn't exist. Which is why the G-Saviour's brief cameo in ''Anime/GundamBuildFighters'' came as such a surprise to the fanbase.
* Not only was [[BizarroEpisode Episode 4]] of ''Anime/TengenToppaGurrenLagann'' cut out of the manga, but the Episode 5 OpeningNarration even refrained from using clips from that episode! The CompilationMovie also skipped over the events of Episode 4, only showing them as part of a travel montage (which makes Kamina questioning who Kittan is later doubly hilarious, as they met in that episode).
* An interesting deal for ''Anime/TenchiMuyo'': the OVA special "Space Police Mihoshi's Space Adventure", which introduced Mihoshi's partner Kiyone (and ''Anime/PrettySammy'', but that was because of Mihoshi's story) was made non-canon by the series' creator, yet it was used as a canon point for another creator's stories using the ''Tenchi'' cast.
* ''Anime/OnePieceFilmZ'' was originally supposed to canon, but Oda decided against it due to the numerous discrepancies between it and the manga. Though most agree that, if anything, villain Z should be a part of canon.
* ''Manga/{{Cyborg009}}'' has at least three stories that Shotaro Ishinomori stated that he personally didn't see as applying to canon, and that fans would be better off ignoring: "Empty War" (which was rewritten and redrawn as "A New Type of Bomb"), "The Man with the Expensive Castle", and a retconned version of the team's origin that acted as a prologue to the Underground Empire arc. The first story is considered old shame by Ishinomori as he had a better idea and revised it, while the latter two incorporated the ExecutiveMeddling-induced change of having 007 be a kid (in order to tie into the then-recent 1966 animated film adaptation of the manga). To make things confusing or perhaps for a completist measure, Tokyopop included ''both'' "Empty War" and "A New Type of Bomb" alongside each other in their US release of the manga, as well as placing "The Man with the Expensive Castle" before the Vietnam arc (when it was originally published after the Mythos arc), leading to a confusing lapse in continuity.
* ''Anime/{{Pokemon}}'': Two episodes of the Best Wishes saga involving Team Rocket fighting Team Plasma that were cancelled due to the 2011 tsunami became non-canon come the Episode N arc, which treats things as if Ash and co. and Team Rocket never met Team Plasma before their actual debut episode.

[[folder:Comic Books]]
* After ''Comicbook/CrisisOnInfiniteEarths'', "Pre-Crisis" continuity (as it became known) became this. And yet, writers sometimes skirted around this, such as when Peter David's Supergirl somehow was able to travel back to Pre-Crisis continuity, begging the question of whether it actually ceased to exist, or just got...cosmically buried somehow. Of course, now that the Comicbook/{{New 52}} is in place, one could be left wondering the exact same questions about the original 1986-2011 Post-Crisis continuity.
* Lampshaded in the Creator/GrantMorrison run on ''Comicbook/AnimalMan'' - Animal Man meets the previous version of himself from another continuity during a peyote trip. The same storyline has him ''meet'' Creator/GrantMorrison later in the series, at which point Morrison [[spoiler:explains that the continuity differences come from [[DependingOnTheWriter different writers writing the same character for different comics]]]]. It also features a character - Psycho Pirate - who [[spoiler: remembers all the alternate continuities that have ever existed, and goes crazy as a result]].
* The ''WesternAnimation/{{Gargoyles}}'' comic, written by the series' original head writer and officially promoted by Disney, ignores the third season, save for the first episode, which it largely retells with the first two issues.
* ''Franchise/SpiderMan'':
** One series written out of continuity was ''Spider-Man: Chapter One'', which ineptly updated several bits of Spider-Man's origin; for instance, the Sandman and Norman Osborn were now related, as a way to explain their ''similar-looking hair''.
** Marvel's [[http://web.archive.org/web/20061123003453/http://www.newsarama.com/000aaaTrouble.htm vague statements]] either took ''Trouble'' out of continuity or implied that it never was in continuity. This series depicted Peter's Aunt May as an unwed teenager and implied she was really his mother. Mark Millar ultimately tried to salvage ''Trouble'' as canon in the last issue, trying to establish it as taking place in the Comicbook/UltimateMarvel Universe via having reference be made to the Ultimate Marvel version of Bucky Barnes (who survived the war and became a famous writer). However, no one else has bothered to pick up on it and it's still a stand-alone story, mostly because it doesn't hold up to anyone with an understanding of basic math. ''[[Comicbook/TheUltimates Ultimate Avengers]]'' seemingly cleared up the issue by establishing that ''Trouble'' is simply a [[ShowWithinAShow comic-within-a-comic]] in the Ultimate universe.
** Despite the claims of a VerySpecialEpisode, Peter Parker was '''never''' molested.
* The writers of the ''Disney Adventures'' ''Series/PowerRangersSPD'' comic conveniently {{retcon}} the reasons behind A-Squad's defection, turning it into MindControl instead of a voluntary FaceHeelTurn.
* ''Comicbook/ArchieComicsSonicTheHedgehog'':
** The infamous "25 Years Later" arc depicted two different alternate futures for Mobius, one of which was ironically created as a result of attempts to change the other. Neither one was mentioned again after the arc ended. Even more egregiously, the character of Lara-Su, Knuckles' and Julie-Su's future daughter and a major player in the arc, vanished along with it, even though her character was introduced in yet ''another'' alternate future story written before "25 Years Later".
** The "X Years Later" timeline was revisited in a ''Sonic Universe'' story, while a later one featured the alternate version of Lara-Su (who was a separate person from the one who appeared in "25 Years Later".
** This seems to be the effect of the past ''two hundred fifty one issues'' following the end of ''ComicBook/SonicTheHedgehogMegaManWorldsCollide'' and its CosmicRetcon ending. WordOfGod states that, yes, those issues ''did'' happen, but it's obvious that they won't have any major standing in the new comics.
* ''ComicBook/JonSableFreelance'': Creator Mike Grell's later uses of Jon Sable have ignored the 27 issues of ''Sable'' written by Marv Wolfman.
* A storyline in ''[[ComicBook/JusticeLeagueInternational Justice League Europe]]'' revealed that Doctor Light's IceQueen behavior was the result of chemicals in a popular soda she enjoyed drinking, leading to the character becoming more personable once she kicked her habit. This was completely ignored by later writers, who brought back her rude, condescending personality with no real explanation.
* ''Franchise/TeenageMutantNinjaTurtles'':
** The third volume of the comic book published by Image Comics, as the official continuation to the [[ComicBook/TeenageMutantNinjaTurtlesMirage Mirage-produced series]], was completely ignored when TMNT co-creator Peter Laird returned to write volume 4.
** Almost all of the "guest era" portion of volume one, which took place from issues 22 through 44 and did not have any input from Laird and Eastman, has been stated to be non canon, with the sole exception of "The River" two-parter from issues 27 and 28.
* In the rebooted series ''[[Comicbook/IncredibleHulk The Hulk]]'', an angry response to writer/artist Creator/JohnByrne's reboot of the title character, particularly his "Man of Steeling" of the Hulk in Annual #1, was responded to in the title's letters page by something along the lines of, "When you not like what happen, do what Hulk do: Pretend it never happened." Thus, the six issues and an annual were simply removed out of existence.
** During Creator/PeterDavid's "Tempest Fugit" storyline, one line discontinuitized the entirety of previous writer Bruce Jones' 42 issue run.
* A particularly brutal version happened in the first issue of the ''[=ClanDestine=][=/=]X-Men'' mini-series. In one line of dialog, Alan Davis (Comicbook/ClanDestine's creator and artist/writer on the original Clan mini) rendered the entire second half of the original mini (i.e. The Issues He Didn't Write) as AllJustADream.
* Keith Giffen's infamous "Five Years Later" TimeSkip in ''ComicBook/{{Legion of Super-Heroes}}'' was motivated by his desire to avoid the many dangling plot threads left over from Paul Levit'z run.
* ''Comicbook/TheWarlord'':
** The 2006 series has been largely ignored in Franchise/TheDCU continuity. With the 2009 series continuing the original series, it seems the 2006 series has slipped completely into this realm.
** Mike Grell's 1992 mini-series off-handedly dismissed the death of Tara which occurred in issues after Grell left the original series.
** The new series seems to ignore Mariah's decision to willingly partner herself with a man who physically abused her. Grell has restored her to her original ActionGirl AdventurerArchaeologist persona.
* ''ComicBook/CountdownToFinalCrisis'' was almost discontinuity. Grant Morrison's ''ComicBook/SevenSoldiers'' led into ''ComicBook/FinalCrisis'' but ''Countdown'' did not. However, Morrison (who also wrote ''Final Crisis'') was forced to cave in and acknowledge ''Countdown'' via a time loop scenario: Darkseid wasn't killed at the end of ''Countdown'' but thrown backwards in time and possessed the mobster who would become Boss Dark Seid, resurrecting his minions in human bodies and consolidating his power base while waiting for his "death" so that he could kill his son and bring the corrupted-by-regular-Darkseid Mary Marvel into his inner circle. ''Alternatively'', Darkseid fell backwards through time after the events of Jim Starlin's ''Death of the New Gods''... but Morrison has stated that the true final war of the New Gods was fought on [[YouCannotGraspTheTrueForm a higher plane than mere mortals could comprehend]], and that ''both'' Countdown and [=DoTNG=] were merely the mortal characters'/writers'/artists' hopelessly limited, three-dimensional perception of what ''really'' happened.
* Years before the ContinuitySnarl of ComicBook/{{Hawkman}}, there was a story, in the original Silver Age 1960s Hawkman series, which threatened to reveal Carter Hall's identity as Hawkman. He ended up protecting his identity but publicly revealing that he's a space alien. Needless to say, this was ignored later.
* An odd example is ''ComicBook/SovereignSeven'', a team of humanoid aliens created by Creator/ChrisClaremont for Creator/DCComics. They were part of the ''Genesis'' CrisisCrossover, and at one point Power Girl became a member of the team. And then, in the final issue, it turned out they were entirely fictional within the DCU. This appears to have been for the opposite reason than most; Claremont wanted to separate his (creator-owned) characters from TheVerse once his book was cancelled.
* ''New Avengers: Illuminati'' #3 has been treated as such, due to the sheer level of CriticalResearchFailure on the part of Bendis regarding the original ''Comicbook/SecretWars'' series and Beyonder.
* The 1990s ''ComicBook/MetalMen'' miniseries [[RetCon reveals that they are actually human minds in robot bodies and has Will Magnus become Veridium]], a Metal Man based on a fictional metal. This change was not well received and quietly dropped from continuity, along with the Metal Men themselves. When Magnus appears as one of the main characters of ''ComicBook/FiftyTwo'' he [[DiscontinuityNod refers to the '90's series as hallucinations resulting from a psychotic break]], and now takes regular anti-depressants to help keep his mind in one piece.
* The "Life and Death of Johnny Alpha" story in ''Comicbook/StrontiumDog'' has explicitly relegated all of Peter Hogan's stories to the realm of {{in-universe}} {{fanfic}}. Garth Ennis' contributions seem to have actually happened.
* Creator/DCComics has a series of books entitled ''The Greatest Stories Ever Told,'' each featuring one character or theme. A Batman volume came out in the late 80s, followed by a volume 2 in the early 90s. V2 was released opposite ''Film/BatmanReturns,'' and features all Catwoman and Penguin stories. Decades later, DC revived its ''Greatest Stories'' series, reprinting the first Batman volume . . . and produced an entirely new ''Greatest Batman Stories Volume 2,'' shoving the previous V2 into no-man's land. (By amusing coincidence, the first volume of Batman stories was the second ''Greatest Stories'' volume overall (after Superman), and thus had ''Greatest Stories Volume Two'' on the spine. So, at a casual glance, all three different books appear to be "Volume Two" of the same series.)
* DC ran an event called ''Origins & Omens'', which had each book featuring an ominous short story hinting at future plots. The ''ComicBook/TeenTitans'' story featured several major revelations, such as Comicbook/{{Static}} joining the Titans, Comicbook/BlueBeetle kissing ComicBook/WonderGirl, Sun Girl becoming pregnant with Inertia's child, and Kid Devil being turned into a withered husk. With the exception of the Static bit, literally all of these plot points were ignored.
* Chuck Austen's ''[[Comicbook/TheAvengers Avengers]]'' and ''Comicbook/XMen'' run is treated as such outside of the BroadStrokes. His characterization of Comicbook/{{Hawkeye}} and [[Comicbook/AntMan Hank Pym]] (whom he {{retcon}}ned into being enemies with no real explanation) was roundly ignored by future writers, and the female Captain Britain (a new Avenger that Austen created) quickly ended up in ComicBookLimbo.
* Devil's Due Publishing's entire seven-year run of ''[[Franchise/GIJoe G.I. Joe: A Real American Hero]]'' (including numerous side titles), intended to be a continuation of the original Marvel storyline, was segregated to its own continuity after IDW Publishing took away the comic book rights from DDP. IDW now publishes its own continuation of the Marvel run (penned by its original writer Larry Hama), reprinting the Devil's Due run under the title of ''G.I. Joe: Disavowed''.
* Creator/OrsonScottCard's ''ComicBook/UltimateIronMan'' revamps Tony Stark in a way that was ignored by every other comic featuring Ultimate Iron Man, creating ContinuitySnarl. Creator/MarkMillar explained that [[RetCon Ultimate Iron Man is]] a ShowWithinAShow in the UltimateUniverse.
* At one point in ''Comicbook/XMen'', the lineup at the time were killed and resurrected, making them invisible to cameras, and this is treated almost as a second mutant power in the next few dozen issues. When Creator/ChrisClaremont left, however, this was completely forgotten, and the lineup at the time - which includes ''Wolverine'', of all people - are seen on camera without comment from then on. His run in 2000 makes a brief mention of this fact with Rogue, but this only serves to muddy the waters further - where it's been mentioned at all, it's explained as a side effect of the Siege Perilous, except that Wolverine and Longshot never went through it, and Rogue ''did''. Common fan explanation is that Roma quietly revoked the "invisibility" gift around the time of the Xtinction Agenda (which is where Claremont actively stopped referencing it) and that the gift itself may have been contingent on the X-Men both possessing and going through the Siege Perilous.
* ''ComicBook/{{Nextwave}}'' is probably the oddest example of this trope ever made. Officially, it ''is'' not canon, but most fans (and quite a few writers!) treats the act of making it discontinuity as a discontinuity in and by itself. This has caused some of the lunacy contained within the series (mainly the parts containing Aaron Stack and the other team members) to spill into the Marvel mainstream.
** The Beyond Corporation from the series later reappeared in ''Comicbook/MightyAvengers''. The official explanation is that the series ''is'' canon, but that thanks to a CosmicRetcon, Monica Rambeau is the only one who remembers it. And even then, for a while she thought she was simply going crazy and remembering adventures that never happened.
* ''ComicBook/SecretInvasion'' ignored the ''[[ComicBook/XStatix X-Statix Presents: Dead Girl]]'' mini-series, where the [[ComicBook/TheAvengers Avengers]] member Comicbook/{{Mockingbird}} appeared in the afterlife. ''Invasion'' established that Mockingbird had never really died in the first place, making the series moot. However, the series' artist Nick Dragotta did later imply the events of the series were somehow still canon when discussing the new Miss America he created for the ''Vengeance'' mini-series, making the ''Dead Girl's'' canonicity difficult to determine.
* Along those same lines, Creator/BrianMichaelBendis brought back Comicbook/TheWasp after killing her in ''Comicbook/SecretInvasion'', with the explanation that she'd never ''really'' died in the first place. However, Wasp had earlier appeared in an issue of ''Comicbook/TheIncredibleHercules'' where she was seen in the Greek Underworld, establishing that she was indeed dead. Though since the fandom was quite happy to have Jan back, there wasn't too much fuss.
* Creator/JephLoeb and Daniel Way's critically-panned series ''Wolverine: Origins'' had the premise of exploring Wolverine's MysteriousPast, which by that point had already been quite fleshed-out, so the series consisted of the writers inserting ''new, unknown'' elements of his history in among the existing stuff, making Wolverine's origin (you know, the thing this series was supposed to be clearing up?) one huge ContinuitySnarl. Among the "revelations" made were the fact that [[ShockingSwerve Wolverine is not a mutant after all but rather a "lupine,"]] a species that looks completely human but is actually [[ArtisticLicenseBiology canine rather than primate in origin]], and that Logan's mysterious, immortal ancestor, the founder of "lupine" society, had been behind basically every threat he'd ever faced, including the Weapon Plus program (even though the mastermind of that had already been revealed as someone else in a far better story). This was swept under the rug almost immediately after the series ended; whenever Logan's species has been referred to since then, he's always been called a human mutant, and the writer of a miniseries set during the same time period as ''Origins'' confirmed he'll be ignoring it, quite simply because it would be too confusing to acknowledge. Except the plot thread is still continuing in ''Wolverine''...
* If a writer writes anything involving the Phoenix Force, it is bound to be rendered non-canon by the next writer that writes something involving Phoenix. Most notably, ''ComicBook/AvengersVsXMen'' ignored the Alan Davis-penned Phoenix Force stories from his Excalibur run, which among other things established the Phoenix Force as Merlin's private energy reserve stash based off of the lifeblood of the universe, as well as establishing that any usage of the Phoenix Force is enough to bring the various cosmic forces down upon the wielder, due to the fact that every time a user uses the Phoenix Force, the collective life force of the universe is drained.
* ''Endsong'', which was a sequel to ''ComicBook/TheDarkPhoenixSaga'', was declared non-canon almost as soon as it was written. It was not until ''Avengers vs. X-Men'' that it was restored to canon, with Wolverine giving a vague recap of the story to the Avengers when discussing the dangers of the Phoenix Force.
* Everything previously established about the White Queen (complete with her being in her 40s) was wiped out by the combination of Creator/GrantMorrison's ''Comicbook/NewXMen'' run and Emma Frost's short-lived flashback ongoing series.
* In the 70's, Comicbook/MortadeloYFilemon author Francisco Ibáñez lost his ownership rights over his characters after a few legal fights with his publishing house. They subsequently hired new, usually unnamed artists to take on the series instead. The change was very noticeable and unsuccessful, so the publishers allowed Ibáñez to retake his series, but under their guidelines. Some years later, the courts awarded him the full ownership rights for the series, and he proceeded to ban the publishers from ever again reprinting any of the books he hadn't authored and [[ChuckCunninghamSyndrome get rid of all the characters he had been forced to write in]] but didn't really like. Interestingly enough, he did save one particular book from the purge, since the artist who had written it was a friend and had asked him for advice- Ibáñez even drew a new cover for it.
* ''ComicBook/AdamStrange'''s late Eighties turn to the DarkerAndEdgier has become this, as most later writers ignored the ideas in it (other than the introduction of Aleea, Adam and Alanna's daughter). Oddly, however, all five issues of this phase have been reprinted by DC in glossy full color, unlike almost any other Adam Strange stories.
* At the end of ''Comicbook/{{Asterix}} and the Falling Sky'', the characters get their memories wiped. This was presumably done because the story broke the established rules of the universe, being a GenreShift into science fiction involving AncientAstronauts. It also had the unexpected upshot of allowing fans to doubly ignore an extremely poorly-written, poorly-drawn and borderline xenophobic story.
* There is an obscure UK-exclusive ''Franchise/{{Transformers}}'' comic called "The Beast Within", wherein the Dinobots merge to form a combiner simply called [[ExactlyWhatItSaysOnTheTin the Beast]], which proceeds to slaughter most of the Decepticons and a number of Autobots before being destroyed. When asked about a Dinobot combiner, Hasbro tends to deny all knowledge of such a thing, indicating they've either forgotten the comic or like to pretend it doesn't exist, something most fans are happy to agree with.
* The ''ComicBook/DarkwingDuck'' comics had crossed over with the ''ComicBook/DuckTales'' comics for their respective final issues. However, The crossover has been officially declared non-canon due to the Joe Books omnibus omitting them. Correspondences with Aaron Sparrow (who was the original editor and rewrote the stories for the omnibus) claim that the story was published without Disney's approval.

[[folder:Fan Fic]]
* Since ''Fanfic/CalvinAndHobbesTheSeries'' is noted to have been in [[Fanfic/Swing123AndGarfieldodiesCalvinverse the same verse]] as Creator/{{Swing 123}} and Creator/{{Garfieldodie}}'s other C&H fics, this places ''Fanfic/CalvinAndHobbesIIIDoubleTrouble'' (by the former) and ''Fanfic/TroubleIsland'' (by the latter) in this, as they'd resolved the long-running CassandraTruth that's still present in ''The Series'', [[SubvertedTrope though do keep in mind that they simply come after]] ''The Series''. ''Fanfic/RetroChill'' has this problem even more, as the status quo is ''massively'' shaken up by the end. This is finally fixed in the bonus chapter of the rewritten ''Fanfic/CanYouImagineThat''.
* The writer of Fanfic/AngelOfTheBat is very fond of [[ShownTheirWork showing his work]] and referencing lots of content from all over Batman and Batgirl's history, but willfully ignores bits of Cassie's backstory, including limiting her speaking ability and making her resentful of her father rather than loving towards him. Red Hood's role also implies Comicbook/CountdownToFinalCrisis doesn't exist in this continuity.

[[folder:Films -- Animated]]
* Franchise/DisneyAnimatedCanon:
** In general the only four Disney sequels considered as canon are ''Disney/TheThreeCaballeros'', ''Disney/TheRescuersDownUnder'', ''Disney/{{Fantasia}} 2000'' and ''Disney/WinnieThePooh''. All of the others aren't. The book ''Disney Dossiers'' fails to mention most of the details about the feature characters established in their TV spin-offs or sequels (e.g. Disney/{{Aladdin}} having a father, [[Disney/TheEmperorsNewGroove Kuzco having a significant other]], [[Disney/TheLionKing and Scar's birth name]]). A Franchise/DisneyPrincess coloring book about [[Disney/{{Aladdin}} Aladdin and Jasmine's wedding]] also for some reason ignored the events of the film's sequels; Iago the parrot isn't attending the wedding at all (at the end of ''Disney/AladdinTheReturnOfJafar'', he made a HeelFaceTurn), and Jasmine's wedding dress for some reason looks absolutely ''nothing'' like the one she wore in ''Disney/AladdinAndTheKingOfThieves''.
** The Franchise/DisneyPrincess roster varies significantly, tending to eliminate princesses from less popular movies. This shows up in merchandise and tie-in books. Most notably, [[Disney/TheBlackCauldron Princess Eilonwy]] and [[Disney/AtlantisTheLostEmpire Kida]] are never included. One book specifically mentions that Ariel is the only princess from an underwater kingdom.
* The writers for the 3rd ''WesternAnimation/AnAmericanTail'' movie, ''The Treasure of Manhattan Island'', caused canon discontinuity for ''Fievel Goes West'' when they had Fievel say that he [[AllJustADream had a dream where the family moved out west]].

[[folder:Films -- Live-Action]]
* ''Film/SupermanReturns'' ignores ''Film/SupermanIII'' and ''Film/SupermanIVTheQuestForPeace'' (and ''Film/{{Supergirl}}''), instead having Superman leave for five years at some point after ''Film/SupermanII''.
* The ''Franchise/{{Godzilla}}'' franchise is particularly infamous for this. Pay close attention here: ''Film/TheReturnOfGodzilla'' (also known as ''Godzilla 1985'') ignored every Godzilla movie except [[Film/{{Gojira}} the 1954 original]]. The Heisei Era movies after ''The Return of Godzilla'' create a new timeline that is very tightly interwoven, with a largely recurring main cast and developing plotlines from movie to movie. The "ignore every previous movie except the 1954 original" reset button was pushed again four movies in a row: ''Film/{{Godzilla 2000}}'', ''Film/GodzillaVsMegaguirus'', ''Film/GodzillaMothraKingGhidorahGiantMonstersAllOutAttack'', and ''Film/GodzillaAgainstMechagodzilla''. The next movie, ''Film/GodzillaTokyoSOS'', was a sequel to the previous film, but the next film after that, ''Film/GodzillaFinalWars'', has an ambiguous continuity that could fit anywhere or nowhere in the series. ''Vs. Megaguirus'', ''GMK'' and ''Final Wars'' all treat [[Film/{{Godzilla 1998}} the American Zilla]] as canon... but have no relation to each other!
* ''Franchise/{{Highlander}}'' is one of the most {{retcon}}ned canons in existence. Almost all iterations of the franchise accept [[Film/{{Highlander}} the original movie]] as canon, with a few various {{retcon}}s, but tend to ignore each other:
** The [[Film/HighlanderIITheQuickening second movie]] retcons when [=MacLeod=] and Ramirez first met, now taking place on an alien planet. The updated version of the second movie re-retcons when [=MacLeod=] and Ramirez first met, now taking place on Earth, but in the distant past.
** The [[Series/{{Highlander}} TV series]] ignores the second movie, and retcons the ending of the first.
** The [[WesternAnimation/HighlanderTheAnimatedSeries cartoon TV]] series accepts some of the flashback stuff from the first movie (there are immortals, two of them are Connor and Ramirez) and ignores everything else, including the bits of the first movie set in 1980s New York.
** The [[Film/HighlanderIIITheSorcerer third movie]] ignores the TV series ''and'' the second movie.
** The [[Film/HighlanderEndgame fourth]] and [[Film/HighlanderTheSource fifth]] movies follows the TV series' continuity, while ignoring the second ''and'' third movies.
** And [[Film/HighlanderTheSource the fifth]] movie has been retconned into AllJustADream via WordOfGod
* ''Film/SleepawayCampIIUnhappyCampers'' and ''Film/SleepawayCampIIITeenageWasteland'' were rendered non-canon by ''Film/ReturnToSleepawayCamp''.
* ''[[Film/OnHerMajestysSecretService On Her Majesty's Secret Service]]'' ''might'' be taken as ignoring ''Film/YouOnlyLiveTwice'', so far as it shows Film/JamesBond and Blofeld meeting face-to-face for apparently the first time (neither recognises the other) when they had already met in the previous film. Of course, both were [[TheOtherDarrin played by different actors]], but in-universe that's no excuse. You can blame PragmaticAdaptation on this, as the book ''Literature/OnHerMajestysSecretService'' precedes ''Literature/YouOnlyLiveTwice'' (where Bond goes to Japan and finds Blofeld there by accident).
* The third ''Film/ChakushinAri'' movie, ''Chakushin Ari: Final'', is promoted like the grand finale to a trilogy but actually ignores the events of ''Chakushin Ari 2''.
* ''Franchise/{{Halloween}}'':
** ''Film/HalloweenH20TwentyYearsLater'', the seventh film, completely ignores the [[Film/Halloween4TheReturnOfMichaelMyers fourth]], [[Film/Halloween5TheRevengeOfMichaelMyers fifth]], and [[Film/HalloweenTheCurseOfMichaelMyers sixth]] films, taking only [[Film/{{Halloween 1978}} the original]] and [[Film/HalloweenII1981 the second film]] as canon.
** ''Film/HalloweenIIISeasonOfTheWitch'' doesn't exist as far as the rest of the series is concerned, and vice-versa. Then again, it was intended to be this from the start, an attempt to turn the ''Halloween'' franchise into an {{anthology}} series where each film was a standalone story related to [[AllHallowsEve the Halloween holiday]]. The idea didn't stick -- audiences awaiting the return of Michael Myers were extremely disappointed when they got a film about witchcraft and evil Halloween masks, and so the producers brought Michael back from the fourth film onwards.
* ''Film/TheRockyHorrorPictureShow'' creator Richard O'Brien almost immediately disowned the semi-sequel ''Film/ShockTreatment'', as did the director of both films, Jim Sharman. (Richard has stated that ''Shock Treatment'', originally written as a strict RHPS sequel but soon to evolve into a completely different film, was a mere abortion.) Richard would eventually write both a movie script (''Revenge of the Old Queen'') and a stage musical (''Rocky Horror: The Second Coming'') that wiped the events of ''Shock Treatment'' out of the canon entirely. However, neither were produced.
* ''Film/{{Predators}}'' dismisses the ''Film/AlienVsPredator'' movies and instead it acts as a sequel to [[Film/{{Predator}} the original film]] and [[Film/{{Predator 2}} the sequel]] (while the events of ''Predator 2'' weren't directly mentioned in ''Predators'', neither was ''2'' said to not be canon).
* In the same vein, ''Film/{{Prometheus}}'' pretty clearly eliminates the ''Film/AlienVsPredator'' movies out of ''Franchise/{{Alien}}'''s canon by stating that Weyland Industries was founded in 2012 by Peter Weyland, rather than Charles Bishop Weyland, who in the AVP films had already had a successful business by 2004.
* NeillBlomkamp's upcoming ''Franchise/{{Alien}}'' film will be a direct sequel to ''Film/{{Aliens}}'', ignoring the {{Contested Sequel}}s ''Film/{{Alien 3}}'' and ''Film/AlienResurrection'' in the process.
* ''Film/UniversalSoldier'' has had numerous sequels with numerous instances of installments ignoring other installments. The first film was followed by two sequels, ''Universal Soldier II: Brothers in Arms'' and ''Universal Soldier III: Unfinished Business'', which were ignored by the next film, ''Universal Soldier: The Return''. The next film, ''Universal Soldier: Regeneration'', ignored every previous movie except the first.
* The third and fourth ''Film/{{Pumpkinhead}}s'' ignore the second, which was tenuously connected to the original anyway.
* The ''Film/{{Jaws}}'' franchise ignored ''Film/Jaws3D'' when creating the sequel, ''Film/JawsTheRevenge''. The tagline even said ''Jaws: The Revenge'' was the final installment in the trilogy.
* The ''[[Series/MysteryScienceTheatre3000 MST3k]]'' film ''Film/BoggyCreek2TheLegendContinues'' is a curious case; Charles B. Pierce produced and directed the original ''Film/TheLegendOfBoggyCreek'', a documentary/dramatic re-enactment about an actual rural legend of a sasquatch-like creature living in the backwoods of Fouke, Arkansas. The studio that owned the film tried to cash in on its popularity and made a full-on fictional sequel, ''Return to Boggy Creek'', without the involvement of Charles B. Pierce. Charles B. Pierce then, out of spite, made his own sequel, completely ignoring the events of ''Return'', combining a fictional narrative about a college nature trip with more dramatic re-enactments of alleged sightings of the creature.
* The 2006 ContinuityReboot of ''Franchise/ThePinkPanther'' as well as its sequel dismisses all of the events of ''Trail of...'', ''Curse of...'' and ''Son of...''.
* ''Film/XMen'':
** ''Film/XMenOriginsWolverine'' is a very well-known example of this trope. After the film came out, no one was really happy with the result (from the fans to the production team. Even HughJackman has stated it didn't feel like a Wolverine movie), and the various contradictions it has with the original trilogy. The prequel franchise was then rejiggered with ''Film/XMenFirstClass'' (containing a completely different Emma Frost) and this film was ignored entirely in ''Days of Future Past'' where even ''The Last Stand'' was taken into account. The upcoming ''{{Deadpool}}'' film will also continue this, since while it has RyanReynolds reprising his role from ''Wolverine'', it will otherwise completely ignore that film and feature a completely different origin for Deadpool.
** As of ''Film/XMenDaysOfFuturePast'', ''Film/XMenTheLastStand'' has been erased through the CosmicRetcon, but it's featured in flashback scenes and its existence is at least acknowledged midway through the film. ''Film/XMenOriginsWolverine'' however (aside from a flashback scene from Victor crushing Logan's claw) is very hard to reconcile with the events shown, and the ending [[spoiler: with Mystique seemingly rescuing Wolverine before he can be sent to Weapon X]] seems to make it clear the film never happened in the new continuity.
** There were also several [[RecursiveAdaptation comic books]] and video games that were touted as [[AllThereInTheManual "official" prequels to the various movies]] that were contradicted by the later films. For instance, the comic book prequel to [[Film/XMen1 the first movie]] and ''X-Men: The Official Game'' both seem to be contradicted by the events of ''Film/TheWolverine''.
* Other than its title, ''Film/TheExorcistIII'' completely pretends ''Film/ExorcistIITheHeretic'' never happened.
* According to ''[[Film/AmericanPie American Reunion]]'', the [[DirectToVideo Direct-To-DVD]] sequels didn't happen.
* ''Franchise/PlanetOfTheApes'': In the third film, ''Film/EscapeFromThePlanetOfTheApes'', Zira states that apes were held as slaves for several generations before rising up, and that a gorilla named Aldo was the first to say "no". But, ''Film/ConquestOfThePlanetOfTheApes'' tried to retcon that out by editing Zira's speech when Caesar watched it on tape. There was a comic, ''Revolution On The Planet Of The Apes'' that tried to repair some of the stuff after ''Conquest'', though its canon status isn't clear. It's possible, though, that the changes in the events of the ape revolution are a result of a changed timeline rather than continuity issues.
* The ''Franchise/ConanTheBarbarian'' film ''The Legend of Conan'' is a sequel to ''Film/ConanTheBarbarian1982'' starring Creator/ArnoldSchwarzenegger. The producers have already stated that it will completely disregard ''Film/ConanTheDestroyer'' as well as [[Film/ConanTheBarbarian2011 the 2011 reboot]].
* The canonical status of ''Film/ANightmareOnElmStreetPart2FreddysRevenge'' in the ''Franchise/ANightmareOnElmStreet'' series has not been clarified by the filmmakers, but it has been ignored by every subsequent sequel.
* ''Franchise/TheTexasChainSawMassacre'': Even discounting [[Film/TheTexasChainsawMassacre2003 the remake]] and [[Film/TheTexasChainsawMassacreTheBeginning its prequel]], which exist in their own separate continuity, every film in the series discounts all the others save for at least [[BroadStrokes parts]] of [[Film/TheTexasChainSawMassacre1974 the original]].
** ''Film/TheTexasChainsawMassacre2'' completely ignores the original film's prescript, which says that the crimes of Leatherface's family were discovered, presumably so there could be a sequel in the first place.
** ''Film/LeatherfaceTheTexasChainsawMassacreIII'' ignores most of the first movie, throws out the second entirely, and is almost a quasi-reboot, but it's really unclear.
** ''Film/TexasChainsawMassacreTheNextGeneration'' ignores both the previous films, though it does make mention of two "minor incidents" occurring since the first movie.
** ''Film/TexasChainsaw3D'' picks up directly after the end of the first movie, ignoring all others in both the main and remake continuities.
* Author Christopher Isherwood was so disgusted at the 1972 film version of ''Theatre/{{Cabaret}}'' - the most "Hollywood-ized" adaptation of his original novel ''Goodbye To Berlin'' - that he not only stood up and protested at the film's premiere (insisting that he never actually slept with a woman, as his on-screen expy did) but wrote the incredibly open tell-all autobiography ''Christopher and His Kind'' in order to tell the 'real' story. Likewise, though allegedly a fan of Christopher's original novel, Jean Ross (who was famously renamed Sally Bowles for the novel) refused to see either the stage or film version. She died shortly after the film's release.
* ''Film/DumbAndDumberTo'' completely ignores the existence of ''Dumb and Dumberer: When Harry Met Lloyd'', most notably with Harry's parents and Freida Felcher being completely different characters.
* ''Franchise/StarWars'':
** Creator/GeorgeLucas has publicly said that the ''Film/TheStarWarsHolidaySpecial'' does not form part of the ''Franchise/StarWars'' canon.
** [[ReCut Han never shot first]]. Lucas has implied through [[OrwellianRetcon burying the original theatrical versions in his vaults]] that the Special Edition second version (Greedo and Han shoot at almost the same time) is the official version of the event.

* ''Franchise/{{Zorro}}'': at the end of ''The Curse of Capistrano'', the main villain was dead, and Zorro publicly unmasked, revealing his identity to everyone. By the third book, neither of those events had ever happened.
* The issue of Lord Soth from the ''Literature/{{Dragonlance}}'' novels, represents perhaps the unholy lovechild of Canon Discontinuity and ExecutiveMeddling. In the novel ''Knight of the Black Rose'', TSR took the famous ''Dragonlance'' character into ''TabletopGame/{{Ravenloft}}'', where he became a [[BlessedWithSuck Dark Lord]]. This did not sit well with one of the original authors of the ''Dragonlance'' series, Mr. Tracy Hickman who, according to rumor, demanded that TSR/Wizards of the Coast {{Retcon}} Soth's trip to Ravenloft, and [[KilledOffForReal killed off the character for good measure]]. And before dying, he repents of his crimes, regains his honor, and swears an oath to pursue redemption in his afterlife. This is a ''giant flaming TakeThat'' against ever putting him in ''Ravenloft'', as one of its conceits is that some people are simply so evil that they're beyond redemption - and its Dark Lords are those people (although TSR averted the discontinuity by publishing ''Spectre of the Black Rose'' which reconciles both viewpoints).
* The rules for thought-speak in ''Literature/{{Animorphs}}'' are as follows: only Andalites, Mercora (in ''Megamorphs'' #2), Leerans (in "The Decision", due to their psychic abilities) and Garatrons (in "The Weakness; their mouthless anatomy is like Andalites') can use it in their natural form, it can be used in any morph including human, and anyone, of any species, morphed or not, can "hear" it. Events contradicting the first two [[EarlyInstallmentWeirdness before KAA settled on the rules]] are not canon.
* The ''Literature/LegacyOfTheAldenata'' novel ''The Hero'', by Michael Z. Williamson and Creator/JohnRingo, was declared non-canon after the publishing of Creator/TomKratman and Creator/JohnRingo's ''Watch on the Rhine'' and later of ''Eye of the Storm''.
* The ''Literature/RedDwarf'' book series starts with two novels, ''Infinity Welcomes Careful Drivers'' and ''Better Than Life'', written by Rob Grant and Doug Naylor (working collaboratively under the pen name "Grant Naylor"). After that, Naylor wrote the novel ''Last Human'' and Grant wrote the novel ''Backwards'' -- both of these act as the third novel in the series, in Canon Discontinuity with each other. This could equally fall under ContinuitySnarl, as ''Last Human'' very briefly {{hand wave}}s the events of ''Backwards'' and then goes off into its own AlternateContinuity.
* ''[[Creator/OrsonScottCard The Worthing Saga]]'' has multiple levels. The actual "canon" consists primarily of the full-length novel. The stories included in the back of a later edition came first, but Card didn't have them on hand when writing the novel, so a lot of the details differ, and he essentially made them an AlternateUniverse. The stories not included are all [[OldShame so awful]] that he wouldn't even discuss them.
* For a while, it was common for Clive Cussler's NUMASeries novels to end in sweeping global changes... that were promptly ignored by later novels in the series. These endings have included such things as the creation of a perfect "Star Wars" weapon system that would make nuclear war impossible, and the United States annexing Canada.
* ''Literature/KnownSpace'' short story "A Darker Geometry" was declared non-canon shortly after it was published.
* Creator/{{Plato}} in ''Literature/TheRepublic'', when discussing censoring stories, starts with the necessity of censoring out all myths that attribute evil behavior to the gods.
* When finishing ''Franchise/TheDarkTower'' series, Creator/StephenKing himself stated right before the very end that fans could just stop reading here if they so wished, and simply be happy with the fact that [[spoiler:Roland reached the Dark Tower and finally entered it.]] What follows ''is'' rather cruel, [[AndIMustScream after all.]] Previously, Roland had stated that the book ''Literature/{{Insomnia}}'' felt 'tricksy and full of lies' and did not read it. A character from the book shows up, but his actions and fate are contrary to how he acts in the Dark Tower.
* In the ''Literature/WarriorCats'' series, ''Secrets of the Clans'' was the earliest guidebook. Five years after its release, several other books had come out, contradicting some of the things it said. [[Creator/ErinHunter Vicky Holmes]] [[WordOfGod stated]]: "I'm afraid Secrets of the Clans is a bit of an anomaly, in that it strayed off the path of rightness in several areas. Please take the Super Editions, and other Special Editions, as canon!"
* The monstrous way the Wizard came to power according to ''Literature/TheMarvelousLandOfOz'' was met with such fan outcry that later books, although they don't explicitly contradict it, never mention it again, and the Wizard has to be told a number of things - in part by Ozma herself - he should have known were it true. But in a sneaky way, what was met with massive outcry when it was published has become an establishing trait in DarkerAndEdgier modern retellings like ''Film/OzTheGreatAndPowerful'' and ''Literature/{{Wicked}}'' where Mr. Diggs ranges from AntiHero to villain. Ruth Plumly Thompson also restored this Wizard's history in ''The Lost King of Oz'' when Pastora was found and returned to Oz. At least once, Thompson mentions the Wizard's embarrassment at his history regarding the king.
* None of the ''Franchise/StarTrek'' novels are considered canon by Paramount. Despite this, when ''Series/StarTrekVoyager'' was still airing on television, the official website stated that Jeri Taylor's novels ''Mosaic'' and ''Pathways'' were canon as they featured background information on the characters of that series. In 2006 (by which point ''Voyager'' had finished airing), the entry was amended to state that they "used" to be considered canon. Also, despite one crossover series, ''Day of Honor'', leading to the ''Voyager'' ep of the same name, they aren't considered canon, either.
* ''Literature/TheChroniclesOfAmber'' disregards the prequels by another author, something Zelazny had established he did NOT want.
* The short stories in the ''Literature/HoratioHornblower'' saga were considered to be less canon than the novels by C.S. Forester and he discouraged the reprinting of ''Hand of Destiny'', ''Bad Samaritan'', and ''Hornblower and His Majesty'' (although they are available if you look). ''Destiny'' in particular contributes to the ContinuitySnarl of the ''Castille'' and Hornblower's powder burns.
* Ian Fleming's ''Literature/TheSpyWhoLovedMe'' was so widely despised - [[CreatorBacklash including by Fleming himself]] - that later novels directly contradict it, and Fleming made it a condition on selling the movie rights to the James Bond books that the producers could only use the title of the novel, not the story.
* The ''Literature/DuneEncyclopedia'' the official companion book to the ''Franchise/{{Dune}}'' series, endorsed by Creator/FrankHerbert was/is considered canon or quasi-canon by some fans. However, Frank's son Brian, having started writing his own prequel novels has made an attempt to officially de-canonize the encyclopedia.

[[folder:Live Action TV]]
* Due to ExecutiveMeddling, the final season of the TV Series ''Radio/OurMissBrooks'' had Madison High torn down for a freeway, and Miss Brooks sent off to teach at a L.A. private elementary school. The Radio series ignored this development, and continued at Madison High as per usual. When [[TheMovie the cinematic]] [[GrandFinale grand finale]] was released the following winter, it also ignored the final TV season.
* ''Series/{{Smallville}}'' episode "Eternal" is bad enough the wiki page has [[http://smallville.wikia.com/wiki/Eternal#Discontinuity a section dedicated to it]].
* ''Series/{{Galactica 1980}}'', the ContestedSequel of the original ''Series/{{Battlestar Galactica|Classic}}'', was long considered mostly noncanonical by fans. When the franchise had its ContinuityReboot in the 2000s, several novels and comics set in the original continuity were released. Those works made it official that the events of ''Galactica 1980'' never happened.
* Many ''Series/XenaWarriorPrincess'' fans do not officially consider the two-part "Friend In Need" arc to be the finale, and neither do the writers of the Xena comics. The ''Dark Xena'' arc is basically a FixFic - constructing a story to undo the finale and other events (such as the death of the Olympian gods). Not only do the comics state that the finale cannot be canon, the show itself makes the events of the final episode dubious at best, since it finished with Xena's soul trapped on Earth as an intangible, invisible ghost. Meanwhile, several episodes throughout the show's run state that Xena and Gabrielle return, reincarnate and generally stick around one way or another forever.
* ''Franchise/StarTrek'':
** The original series episode [[Recap/StarTrekS1E14BalanceOfTerror "Balance of Terror"]] is highly regarded. However, its assertion that the Romulans do not have warp drive was [[ScifiWritersHaveNoSenseOfScale questionable at the time]], and was understandably ignored in ''Series/StarTrekEnterprise''.
** The anti-religious view displayed in the ''Series/StarTrekTheNextGeneration'' episode [[Recap/StarTrekTheNextGenerationS3E4WhoWatchesTheWatchers Who Watches The Watchers]] was never, ever brought up again.
** ''Series/StarTrekVoyager''[='=]s "Threshold" is so badly regarded that it was explicitly stated to be non-Canon by the producers while the show was still in production and later directly contradicted on-screen.
* ''Series/NinjaTurtlesTheNextMutation'' was one of the inspirations for a whole {{retcon}} of the franchise. The producers even reassured fans that [[TheScrappy Venus de Milo]], outside of history books of the series, would never, ever, ever be mentioned again. The disowning is further pronounced in ''WesternAnimation/TurtlesForever'', where ''The Next Mutation'' (as well as other TMNT oddities best left in the depths of obscurity such as ''WesternAnimation/CartoonAllStarsToTheRescue'' and the musical) is missing from 2003 Shredder's slideshow of TheMultiverse (and just for kicks, even the ridiculously absurd anime {{O|riginalVideoAnimation}}VA is acknowledged in that same scene). Production-wise, this can be explained away by rights issues, but ''everyone'' knows no one wanted to dredge up those continuities again.
* In the ''Series/{{Charmed}}'' episode "All Hell Breaks Loose", the supernatural is exposed to the general public when the Charmed Ones fight a demon before a news crew, causing a chain of events that ends up in Prue's death. However, the episode "Forget Me... Not", introduces the Cleaners, magical beings tasked with "cleaning" such exposures. However, thanks to time travel, that exposure no longer happened. [[FridgeBrilliance Maybe that's what the Cleaners intended all along, and the Charmed Ones just didn't see them.]]
* Creator/{{NBC}} has repeatedly ignored the existence of the 1980-81 season of ''Series/SaturdayNightLive''. In the season-by-season Best Of series, this was the only one skipped, with "The Best of 1980" containing material from the last episodes featuring the original cast. The 15th and 25th Anniversary specials ignored it, save for clips of its musical guests, and the 25th special's opening titles contained a cast photo from every season EXCEPT that one. (Each photo on the film strip is even labeled with the year - 1979 and 1981 have nothing between them.) Additionally, episodes from the 1980-1981 season are rarely shown in syndication. The only season six episodes that have aired in syndication are: a one-hour version of the last episode produced by Jean Doumanian[[note]]with host BillMurray, who despised everyone in the new cast except EddieMurphy[[/note]] that aired on ComedyCentral as part of a weekend marathon called "The Eddie Murphy Experience" and again on Comedy Central's "50 Greatest ''SNL'' Episodes" marathon that came on around the time the syndicated reruns were being retired, a one-hour version of the infamous episode hosted by Charlene Tilton where Charles Rocket ends the show with, "Oh, man. This is the first time I've ever been shot. I'd like to know who the fuck did it" as part of VH-1 Classic's ''SNL'' Rewind marathon, a one-hour version of Eddie Murphy's first episode as a repertory player [[note]]hosted by Robert Hays from ''Airplane!''[[/note]] also part of the ''SNL'' Rewind Marathon, and a full 90-minute version of an episode hosted by Jamie Lee Curtis that aired on NBC (and didn't air on many affiliates due to Pope John Paul II's assassination attempt making the news). It seems as though, in recent years, the ban on 1980-1981 season episodes has loosened a bit due to the Internet and news of Charles Rocket's suicide in 2005. Netflix once had season six as part of the show's 1980s collection[[note]]though the episodes were edited due to musical licensing[[/note]], some season six clips are available for viewing on NBC's ''Saturday Night Live'' page, there was a documentary on the show's rocky history in the 1980s that included a piece on Jean Doumanian's tenure with episode clips, stills, and commentary from former cast members Denny Dillon, Gilbert Gottfried, and Joe Piscopo), many books centered on the show's history (including ''Live From New York: The Uncensored History of SNL'') do touch on this dark age, the Catherine Zeta-Jones episode from season 31 (which premiered two weeks after Rocket's death) had an InMemoriam still of Rocket at his Weekend Update desk, and the 40th anniversary special included Charles Rocket in the montage of cast and crew members who died during the years.
* {{Game Show}}s:
** The 1985-86 ''Series/{{Break The Bank|1985}}'', which aired in syndication. The first 13 weeks (a quizzer where couples earned seconds to be used in silly stunts to earn Bank Cards to possibly break the Bank) were hosted by veteran game show host [[Series/MatchGame Gene Rayburn]], who got into arguments with the producers because they thought he shouldn't be joking around during their serious and suspenseful show (no, seriously). Rather than do something about it, they fired Gene and brought in Joe Farago; a few weeks later, they dropped the stunts in favor of a $2,000 front-game goal and a Master Puzzle. Subsequent reruns were only of the Farago episodes, with no mention of Rayburn or acknowledgement that he had ever hosted in any future airings. (It's unclear how much, if anything, Rayburn had with his shows not being rerun.)
** The producers of ''Series/PressYourLuck'' wouldn't allow either of the two episodes featuring Michael Larson (June 8 and 11, 1984) to air on Creator/{{USA|Network}} or Creator/{{GSN}} until 2003. The only indication that he'd even been on the show was the re-randomization of the board patterns.
** ''Series/ThePriceIsRight'' has several examples of omitting its history. Long-time host Bob Barker has absolutely refused to allow episodes where fur coats and other products made primarily from animal carcasses were offered as prizes. He vetoed episodes featuring ex-model Holly Hallstrom (more than 2,000 episodes from 1977-95) with explanations varying, although Barker and Hallstrom had a hostile relationship at least during the later years. Barker also refuses to discuss or even acknowledge longtime announcer Rod Roddy; this is likely because Roddy, who died in 2003, had a salary dispute with Barker, which in turn explains why Roddy did not appear on camera in his later years. And don't even ask how Dennis James, who hosted a weekly nighttime version alongside the daytime show for its first five years, falls into this. Most of the 1972-80 nighttime run contained furs, but GSN refused to show the remainder and only pulled out a daytime substitution from December 25, 1974 after James died in 1997.
** ''Series/WheelOfFortune'', despite running daily since '''[[LongRunners 1975]]''' and debuting with Chuck Woolery and Susan Stafford, seems intent on putting forth the deception that it began in 1981 (or 1983) with Pat Sajak and Vanna White. This may be due to Woolery leaving after salary disputed with creator Creator/MervGriffin (he wanted $500,000; Merv offered $400,000). Bizarrely, for their ceremonial 3,000th nighttime show in 1998, ''Wheel'' showed clips of Edd Byrnes' first pilot (taped August 28, 1974) and name-checked him. They then claimed that what we were seeing was '''the''' pilot, disregarding not only another pilot taped later that day but also the original 1973 pilot ''Shopper's Bazaar'', hosted by Woolery. They also seemed intent to, in Season 28, erase any idea that they taped out of order after Charlie O'Donnell died: he had done another eight weeks that had yet to air, but these were dubbed over by various substitutes as ''Wheel'' claimed "it was a tough decision, but it would have been too sad to hear his voice so close to his death". In Summer 2011, the sub-announcer shows were dubbed over by the just-hired Jim Thornton. To say fans were displeased with these decisions would be putting it '''extremely''' mildly.
* ''Series/BuffyTheVampireSlayer'' mostly ignored [[Film/BuffyTheVampireSlayer the movie]] it was based on. The only real references to it are that Buffy was kicked out and the whole Watcher/Slayer relationship. Worth noting is no mention of Pike and only a brief mention/scene of Merrick being her first Watcher (who looks extremely different from Donald Sutherland) in a late Season 2 episode. And then there were multiple references of "burning down the gym to kill all of the vampires in it", a part missing from the movie. Technically the series isn't based on the movie as aired, but on the original script (written by Creator/{{Joss|Whedon}}) the movie was ''[[ExecutiveMeddling based on]]'', which included Buffy burning down the gym.
* The Creator/BigFinish version of ''Series/TheTomorrowPeople'' includes a list of ''homo superior''s who died when their powers first manifested. This turns out to include the characters from the 1990s {{Revival}}.
* ''Franchise/PowerRangers'':
** After Saban re-acquired the franchise, executive producer Johnathan Tzachor made a post on the official message boards saying that he considered every season made by Disney (from ''[[Series/PowerRangersNinjaStorm Ninja Storm]]'' through ''[[Series/PowerRangersRPM RPM]]'') non-canon. [[LyingCreator That is]] until the news came that Toei was filming a [[Series/KaizokuSentaiGokaiger Legend War]] sequence for the 20th Anniversary, and all the teams (both from Saban and Disney) are a part of it. (Then again, Tzachor also claims that every incarnation of the franchise is its own continuity, even when all onscreen evidence claims otherwise, so fans are generally content to ignore him.)
** Saban has said that ''[[Series/PowerRangersRPM RPM]]'' is non-canon until they need to reference it or do a crossover, at which point it'll become canon. This is easier to understand than the above, since ''RPM'' is an AfterTheEnd series that implies a cruel fate for at least [[Series/PowerRangersOperationOverdrive one past Ranger]]. When the time came to canonize it in a crossover with ''Series/PowerRangersSamurai'', it was explained as being an alternate universe.
** Conversely, Paul Schrier mentioned at Comic-Con 2011 that, while the current Saban Brands production regime [[SeasonalRot does not like]] the Disney seasons and wishes they did not exist, they are in-continuity and have not been disowned.
* ''Series/StargateSG1'':
** Early on, the Zat gun was said that "one shot stuns, two shots kill, and three shots disintegrate." They used the third shot a few times until they realized [[SciFiWritersHaveNoSenseOfScale how much energy that would actually require]], and this element was quietly dropped. This was later self-parodied in "[[WhoWouldWantToWatchUs Wormhole X-treme!]]" with one of the writers saying: "That is the stupidest thing I've ever heard."
** The difference between the show and [[Film/{{Stargate}} the movie]] is extreme. Ra goes from being the LastOfHisKind to the leader of the Goa'uld System Lords. Abydos is moved into the Milkway from another Galaxy. The Jaffa are invented and Ra's species made into the Goa'uld. WordOfGod explained the movie's Ra being one of TheGreys as him having implanted himself into an Asgard. The way the Stargate functions is also considerably different in the movie than in the show. However, references to the movie's events never stopped, and many fans will point out we never had it on good authority that Ra was the last of his kind (the tablet Daniel read from said he escaped his dying world; it's unclear what led people to jump to the conclusion that there was absolutely no way anyone else did the same.) ''SG-1's'' relationship with the movie is "[[BroadStrokes the movie mostly happened, but we change what doesn't work for us]]", although one change that was inconsistently handled due to the writers [[OmnidisciplinaryScientist not knowing how to write for her]] were mid-season episodes that claimed Sam was responsible for making the Stargate work and kicking off the Stargate Programme: that credit is supposed to lie with Daniel Jackson, which a lot of episodes do acknowledge.
** The episode "Hathor" was effectively struck from canon due to the writers considering it the worst episode they ever wrote. Hathor reappeared later at the head of a Jaffa army she'd brainwashed away from several other Goa'uld, but [[BizarreAlienSexes how Goa'uld queens work]] was retconned due to the {{squick}}iness of the original explanation, and characters would [[LetUsNeverSpeakOfThisAgain refuse to talk about the events of the episode when asked]].
* This existed between the ''Franchise/{{Highlander}}'' movies and series to the point of {{Continuity Snarl}}s at times. (see the Film entry)
* ''Series/{{CSI}}'':
** Official info on the CBS character bios was changed and/or ignored. The bios had Catherine being born in Bozeman, Montana (probably recycled and given to NY's Lindsay) and having a sister, and Grissom's father being involved in smuggling. Making it worse was this information being included in the first episode guidebook that was released.
** The famous "Danny was from a family of cops" stuff. The producers retconned by saying "extended family", but many still don't buy it.
* ''Series/SamAndCat'', which is a SpinOff that takes one character from ''Series/ICarly'' (Sam) and one from ''Series/{{Victorious}}'' (Cat), appears to retcon the ''iParty With Victorious'' CrossOver episode from those two prior franchises. Instead of the pair recognising each other from the events of that episode with them meeting each other in person and spent much of the episode together, Cat only recognises Sam by way of Cat knowing about the Series/ICarly webshow.
* Austrian series ''Die Piefke-Saga'', part 4. The series parodied German tourists in Austria and the industry in general. Said part was set in the future, where Tyroleans were replaced by androids, while the last remaining natives had become LaResistance.
* ''Series/SesameStreet'' is constantly retconning itself due to having a sliding timeline.
* ''Series/OnlyFoolsAndHorses'''s writer, John Sullivan usually liked to pretend that the 1986 Christmas Special, "A Royal Flush" never happened, due to Del being absolutely cruel to Rodney by ruining his chances with the daughter of an aristocrat. Sullivan only allowed the episode to be released on video and DVD due to demand from the fans, and even then it was in the form of a severely edited version in which Del is a lot less mean.
* ''Series/DoctorWho'':
** MissingEpisode reconstructions occasionally use this to 'fix' things the BBC would rather didn't happen. For example, the interview with Anneke Wills at the end of the official audio reconstruction for "The Underwater Menace" reveals that she and the director had agreed to alter a part where [[GetAHoldOfYourselfMan Jamie slaps Polly in the face to get her to stop freaking out]] because, in addition to being unnecessarily chauvinistic, it was [[OutOfCharacterMoment really out-of-character for Jamie]] (who had [[CharacterizationMarchesOn just recently been introduced]]). In the reconstruction, he merely roughly pulls her to her feet, which is enough of a shock to shake her out of her panic. Another example is how the reconstructions deal with [[ValuesDissonance the random racial slur]] in "The Celestial Toymaker" - the BBC's official reconstruction buries it by having the narrator talk over the top of it, and the semi-official Loose Cannon reconstruction edits the line out entirely.
** Between the nonsensical plot and the perceived bad quality, "[[Recap/DoctorWho30thASDimensionsInTime Dimensions in Time]]" has been officially stated by the BBC never to have happened (both the webpage and the ExpandedUniverse agree that it is AllJustADream) despite having been intended at the time to be canon (as, in the eyes of the producer, bad canon was better than no canon at all).
** "WebAnimation/DeathComesToTime" totally ignores the events of the TV Movie (the Doctor is still the Seventh Doctor) and serves as an 'ending' for the show.
** "WebAnimation/ScreamOfTheShalka" was an attempted {{Reboot}} and introduced a new Doctor and a new Master, now his companion. Hopes were to use it to get a new series launched, but the eventual actual revival made a point of ignoring it as Creator/RussellTDavies strongly disliked it.

* Music/TheDivineComedy's first album, ''Fanfare For The Comic Muse'', is very firmly this; it's been long deleted, and nobody - least of all Neil Hannon - seems to want it rereleased.
* Music/ToriAmos and Music/{{Genesis}} do their best to pretend their first albums don't exist. ''Y Kant Tori Read'', like ''Fanfare'', is long deleted, and ''From Genesis to Revelation'' probably would be if anyone from Music/{{Genesis}} had their way, but they don't own the rights to it, their then-manager does. Music/{{Genesis}} also likes to pretend that the widely panned album ''Calling All Stations'' (featuring Ray Wilson on lead vocals) never happened either. No songs from that album were included on the 2006-2007 reunion tour.
* Music/DavidBowie never includes his first self-titled album (his second self-titled album was later renamed "Space Oddity") in his discography. His early novelty song "The Laughing Gnome" is generally acknowledged as something that ''should not and should have never existed''. When {{Troll}}s hijacked a fan vote for what songs he should play on a tour so that it came high up, he scrapped the poll altogether. And ''Never Let Me Down'' (1987) is not only often considered his worst canonical album, but one song on it ([[http://www.teenagewildlife.com/Albums/NLMD/TD.html "Too Dizzy"]]) was [[http://en.wikipedia.org/wiki/Never_Let_Me_Down#Reissues dropped from reissues.]]
* Music/{{Eminem}}'s debut album, ''Infinite'', was a complete commercial failure, and has never been reissued. The songs featured a very young Eminem performing in smooth R&B styles he would never revisit, and none of the material has reappeared in any form. (While his second release, ''The Slim Shady EP'', has also never been reissued, most of the material was either repeated or remade for ''The Slim Shady LP''.) He does, however, reference it in ''Recovery'' song Not Afraid:
-->"From "Infinite" down to that last "Relapse" [[note]](Relapse: Refill)[[/note]] album..."
* Both Music/AlanisMorissette and Music/{{Bjork}} have [[OldShame embarrassing early albums]] they don't acknowledge as part of their discography; Björk's was an LP of covers recorded when she was a child, while Alanis' were teen pop which won her fame in Canada but failed to chart in the US.
* Music/TheDoors have never reissued their two post-Morrison albums, ''Other Voices'' and ''Full Circle'', even in the supposed ''Complete Studio Recordings'' boxed set. These have allegedly only seen CD release in Russia, and those discs are very likely unauthorized. Both albums eventually became available on iTunes.
* Both the fans and Music/{{Helloween}} themselves agree that there's no such thing as ''Chameleon'' in their discography. It was the last album with Michael Kiske on vocals, and the most LighterAndSofter of them all. Nowadays ''Pink Bubbles Go Ape'' has fallen here as well, despite that the band played some of that album's songs, like "Mankind" and "The Chance".
* While ''Music/TheFinalCut'' still exists in the mind of Roger Waters (who still performs its material live), the album was shunned by the other members of Music/PinkFloyd, who had very little input in the disc. David Gilmour in particular was disgusted that Roger would not only fashion a new album out of rejects from ''Music/TheWall'', but have the nerve to credit Pink Floyd as [[IAmTheBand mere sidemen]] on his 'requiem for the post-war dream.'
* For Music/{{Pantera}} and their fans, their first album was 1990's ''Cowboys From Hell'', [[OldShame ignoring the previous 4 albums a.k.a. their hard rock/glam era]].
* The third verse of the British national anthem, "God Save The Queen" is now discarded as it is [[LighterAndSofter deemed too belligerent:]]
-->O Lord our God arise,\\
Scatter her enemies\\
And make them fall.\\
Confound their politics,\\
Frustrate their knavish tricks,\\
On Thee our hopes we fix,\\
God save us all.
::The very dated verse six, which makes reference to George Wade and his "rebellious Scots to crush" has also proved worthy of omitting, for obvious reasons.
* Only the third verse of "Deutschlandlied" is part of the German national anthem. Verse 1 was already being questioned for its apparent belligerence and imperialism before it was co-opted by the Nazis. It also doesn't help that the borders described in the stanza are now part of other nations, and part of getting four-power assent to German reunification was dropping claims to Silesia, Pomerania and East Prussia. Verse 2 is jingoistic self-aggrandizement that is... [[ValuesDissonance a bit awkward now]], to say the least. Verse 4 was a Nazi invention, so... yeah.
* The third stanza of "The Star-Spangled Banner" is often omitted in official renderings, because it mocks the British military as "hirelings and slaves". Of course, Britain is now a key ally of the USA, making the verse very outdated.
* Both Music/{{Metallica}} and Music/{{Megadeth}} will generally pretend that the eighth album in each of their discographies, ''St. Anger'' and ''Risk'', don't exist. "Generally" is a key word: the material is rarely, if ever, performed in current concerts, but both bands will admit to the albums' existence if pressed hard enough.
* Music/{{Devo}} has generally ignored the entire Enigma Records discography, and their last Creator/WarnerBrosRecords album, "Shout". While they acknowledge their existence, good luck hoping for a re-release, or hearing anything from it performed live again.
* Music/OzzyOsbourne has deleted the live albums ''Speak of the Devil'', ''Just Say Ozzy'', ''Live and Loud'' and even the studio album ''The Ultimate Sin'' from his catalog, and they are no longer being made. The deletion of ''The Ultimate Sin'' most likely has something to do with the legal troubles with a former band member over songwriting credits. At the time it was released (1982) Ozzy made no bones in interviews about hating ''Speak of the Devil'' passionately; he did it only because he was contractually obligated to do a double live album with a lot of Sabbath classics at the time (and the shows in question were recorded mostly after Randy Rhoads' sudden death, not a good time for Ozzy). It helped him out a lot because his versions were a lot better than what his former bandmates served up on ''Live Evil''. It's not a great surprise that as soon as he could put it out of print, he did so.
* The Goo Goo Dolls started as a HardcorePunk band, evolving into a PopPunk sound that produced both their major label debut ''Superstar Car Wash'' and their commercial breakthrough album ''A Boy Named Goo''. The follow-up, ''Dizzy Up the Girl'', introduced a ballad-oriented folk-pop sound that brought them even greater commercial success. They no longer perform/discuss the old material for obvious reasons. Their 1987 debut ''First Release'' has been out of print since...1987, and when asked what the chances of them ever playing the pre-''Car Wash'' material again were, they said "take the highest number you can think of and multiply it by three".
* ''[[Music/{{Squeeze1973}} Squeeze]]'', the final album by Music/VelvetUnderground, was never reissued to CD or MP3 format and has been out of print on vinyl since the early 80s. It also sounds [[NewSoundAlbum very unlike anything else by The Velvet Underground]] due to the absence of [[FaceOfTheBand Lou Reed]] or anyone else associated with the band aside from Doug Yule. It is also the only album left out of the otherwise retrospective compilation ''Peel Slowly and See.'' The only reason anyone tried to call it canon in the first place was ExecutiveMeddling. Doug Yule wanted to release ''Squeeze'' as a solo album.
* Music/JudasPriest seems to have all but forgotten about the era of Tim "Ripper" Owens now that Rob Halford is back. In fact, a 2012 box set called "The Complete Albums" contains the band's first two albums (the first release on CD endorsed by the band) but ignores both albums with Tim Owens.
* ''Music/VanHalen III'', the group's only album with Gary Cherone is not mentioned on VH's official website nor do songs from it appear on any GreatestHitsAlbum.
* Music/TheBeatles:
** Music/PaulMcCartney clearly considers ''Music/LetItBe'' to be this, while Music/JohnLennon didn't (George and Ringo were either apparently neutral or didn't make their views on the subject known). The reason for this stems from CreativeDifferences; the album was recorded during a period of tension between the band, and the recordings were shunted aside until producer Phil Spector was brought in to sort them out and make something presentable of them. However, either through oversight or spite no one actually let [=McCartney=] know what was going on, so while Lennon was satisfied [=McCartney=] was horrified to hear what had been done to his original songs (especially "The Long and Winding Road") without his knowledge or permission. ''Let It Be... Naked'', released over thirty years after, is generally considered an attempt by [=McCartney=] to replace the original.
** The American Beatles albums are ignored, with the occasional exception of ''Meet The Beatles''. The canon established in the 1980s with the CD releases and re-mastered in 2009 includes only the UK albums, except for ''Music/MagicalMysteryTour,'' which was never a proper album in the UK, just two [=EPs=]. The live album ''The Beatles Live at the Hollywood Bowl'' has never been released on CD due its awful sound quality, and the early bootlegs ''The Star Club Tapes'' were actively suppressed by the Beatles for the same reason.
* Since it was the only Music/{{Yes}} album made without him, Jon Anderson refused to perform any material from ''Drama'' live.[[note]] Yes reformed without Anderson in 2008 and has since recorded two albums with two other vocalists.[[/note]]
* Music/TheKLF did this to their entire back catalog when they left the music business in 1992. Well, specifically they pulled all of their albums out of print to make it clear that their retirement wasn't just a stunt to sell more of their back catalog. Only in the UK, however; one can still buy copies of their American Arista releases. The American releases (and remaining UK copies) have been [[KeepCirculatingTheTapes in high demand with British fans]] since the band retired.
* Robyn Hitchcock disowned his second album ''Groovy Decay'': He pulled it out of print a few years after it's release and replaced it with ''Groovy Decoy'', which featured the original versions of four ''Groovy Decay'' songs but mostly consisted of demos from the same period. The original ''Groovy Decay'' album can still be found in it's entirety on the box set ''Gravy Deco'' though, and the album even got a 2007 remastered re-release with bonus tracks, although it was only released as a digital download.
* The Music/BobDylan album ''Dylan'' was released without his approval by Creator/ColumbiaRecords after he jumped ship for Asylum Records, pieced together from some dubious outtakes. After he returned to Columbia several years later, it was quietly buried and largely has remained so ever since. A similar thing seems to have happened to his debut ''[[Music/BobDylanAlbum Bob Dylan]]'', which is often overshadowed by all the albums that came next.
* Scooter:
** Their first single Vallée Des Larmes has been all but ignored. HP Baxxter introduced his signature rapping/singing style on their second single Hyper Hyper, which was successful. Vallée Des Larmes was not included on an album and its only recognition by the band since is the inclusion of a Remixed version on the 1998 compilation Rough And Tough And Dangerous. It appears on the bonus disc, as the remix was a B Side. The reason for them ignoring Vallée is because it's an instrumental, it wasn't successful and it was recorded at a time when Scooter were meant to be a one off project. Its main B Side Cosmos appears on the band's first album And The Beat Goes On, however. In later years, they have acknowledged the influence they had on Scooter and the band have done the odd darkwave inspired song since. They have admitted that it was more financially viable playing Scooter's style of music.
** Sheffield is definitely the OddballInTheSeries and they aren't fond of its lead single "I'm Your Pusher". The second single from the album, "She's The Sun", is widely regarded as one of the band's best songs, but it doesn't really fit in with their repertoire these days. No tracks from the album were included on the UK version of their Push The Beat For This Jam compilation, but they have been on all others.
* Neither of the two original videos for Music/{{Madonna}}'s first single "[[http://www.youtube.com/watch?v=0X7RyGBq2E8 Holiday]]" from her debut ''[[Music/MadonnaAlbum Madonna]], which featured the pre-MTV, pre-''Lucky Star'' singer dancing in a production studio (featuring an observer dressed in a nightgown in the background), have been included on any of her official video releases. This included 2009's ''Celebration'' DVD collection, which collected almost every other music video she ever released (including a live performance of "Holiday", shot at the same time as the videos). Notably, both versions featured poor production values. In the same vein, the original music video for ''Music/TrueBlue'' (which didn't feature Madonna in it) has never been acknowledged either, due to it being helmed by an amateur director who won an MTV "Make My Video" contest in 1984. Madonna has also refused to play the song at most of her concerts, as the song was written about her (abusive) ex-husband Creator/SeanPenn, after they divorced in the late 1980s.
* The second album by Music/BadReligion, ''Into The Unknown'', actually got better reviews than their first album, but was rejected by fans because it explored prog-rock influences and piano melodies. After selling poorly, it was ignored in the discography for years, only being reissued 27 years later (in vinyl only) as part of a box set.
* CountryMusic singer Joe Nichols has an album titled ''III''. It was his fourth album. The one that was excluded from the chronology? His obscure 1996 self-titled debut on a small indie label — although none of its singles charted in the US, one got to #74 on the Canadian country charts, and all four had music videos.
* Bomshel seemed to quickly ignore the fact that Buffy Lawson was ever one-half of the duo (the other half being Kristy Osmonson). The Lawson/Osmonson pairing recorded a three-song EP, from which all three cuts charted, and a song for the soundtrack to ''Film/EvanAlmighty''. After Kelley Shepard replaced Lawson in 2008, the new lineup quickly tossed aside three of the four songs from Lawson's tenure, keeping only "Bomshel Stomp", before disbanding in 2013.
* Music/TheyMightBeGiants' first-ever music video was for "Rabid Child," created around the time of the song's debut on their ''1985 Demo Tape''. The band very reluctantly allowed a brief fragment to be shown in their ''Gigantic'' documentary in 2002, but will refuse any discussion concerning a full public release. No one knows why.
* Al Jourgensen completely disavows his first album ''With Sympathy'', calling it an "abortion." It's a very poppy dance album as mandated by his record label, sounding nothing like the metal/industrial band they would become. This was also a period of time when Al sang in a faux English accent for reasons he doesn't even know/remember. He does still acknowlege his first single "Every Day Is Halloween" that predates the album. While also a poppy dance number, it remains a fan favorite.
* ''Music/{{Shakira}}'' released two albums as a child before her breakout album "Pies Descalzos", however, they were critical and commercial failures and aren't listed on her oficial discography.
* Music/KatyPerry's website doesn't mention any of her Christian albums recorded under her real name, Katy Hudson.
* Ads for Jerrod Niemann's 2014 single "Buzz Back Girl", the third single from his third album ''High Noon'', seem to take the stance that the preceeding single "Donkey" never happened. This is most likely due to "Donkey" being a ''highly'' polarizing DoubleEntendre-laden novelty that completely self-destructed on the charts, dying at #43 only a few weeks after the album's lead single "Drink to That All Night" hit #1.
* Music/BrooksAndDunn seemed to take the stance that their 1999 album ''Tight Rope'' never happened, despite producing a Top 5 hit in "You'll Always Be Loved by Me". The album was their worst-selling and least successful on the charts, was derided by critics for its tired sound, and had none of its singles appear on their second GreatestHitsAlbum in 2004. Making this omission more egregious is the fact that said Greatest Hits album ''does'' feature "South of Santa Fe" from the album immediately before ''Tight Rope'', which has the dishonor of being their only single not to hit Top 40 on the country charts! (By comparison, their second lowest charting single is "Beer Thirty" from ''Tight Rope'', which still got to #19.)
* Music/TaylorSwift does not perform any of the singles off her debut album, except for an occasional performance of "Our Song" in a more pop style.
* CountryMusic singer Rodney Atkins has disowned "Honesty (Write Me a List)", the only hit from his 2004 debut album, possibly due to EarlyInstallmentWeirdness that put it out of line with the style he developed by "If You're Going Through Hell" two years later.
* For a long time, Music/NewOrder refused to play any Music/JoyDivision songs, wanting to avoid comparisons between them and their former incarnation. Once they felt they'd developed a musical reputation in their own right, they started doing songs like "Transmission" and "Love Will Tear Us Apart" in live shows.
* The Internet didn't seem to indicate the existence of any Music/ImagineDragons [=EPs=] older than 2009, until [[http://imaginedragons-ep.tumblr.com/ some songs]] from a 2008 EP called ''Speak to Me'' appeared on Website/{{Tumblr}} in December 2014. (A few other websites acknowledged the existence of the ''songs'', but not the EP itself.) The band's manager, Mac Reynolds, [[https://i.reddit.com/r/imaginedragons/comments/2qo2jg/demo_ep_speak_to_me_ep_download/.compact explained]] that since only one of the members featured in those tracks-Dan Reynolds-remained with Imagine Dragons afterward, the band didn't really consider ''Speak to Me'' one of their own works.

* ''Franchise/{{Bionicle}}'':
** The climax of the 2001 storyline is a major ContinuitySnarl which the authors solved by applying this trope. The first book, a web game and a scrapped video game all depict the event - involving a FusionDance, a battle with [[GiantEnemyCrab Manas]], then a confrontation with [[BigBad The Makuta]] and [[ThePsychoRangers Shadow Toa]] - in irreconcilable ways. According to WordOfGod, the events went as follows: The Kaita are formed inside two devices before the fight with the Manas. There are only two Manas, and are defeated by demolishing energy-towers. Makuta's presence separates the Toa, who then fight their Shadow counterparts. These are defeated by the six Toa each absorbing their own clones into themselves. Then Makuta is fought and defeated, and the Toa are teleported to the surface, which has been kept clear of Makuta's Rahi forces by the villagers' army.
** Most of the beginning of the novel ''Makuta's Revenge'' has been scrapped in favor of the way the scenes played out in the on-line animations.
** The introduction of the movie ''The Legend Reborn''. It has so many things that clash with the storyline's continuity, whether established previously or afterwards, they simply chose to ignore it. That is not to say the ''events'' themselves didn't happen. They just happened in a way that contradicts the movie's visuals (like Mata Nui's island is shown being covered with lush jungles when according to canon, it was a barren wasteland).
** A couple of things from the on-line clips and the first movie trilogy get ignored, most infamously the shipping scenes, as there came to be a NoHuggingNoKissing rule.
** Taxi crabs were considered dis-canonized for years because the writer didn't like the joke. They slowly drifted back into canon territory, though.
** The part about the tribes on Mata Nui renaming themselves from "Tohunga" to "Matoran", [[ExecutiveMeddling due to legal reasons]] in real life, was dropped. They later made a RetCon so that they've always been called Matoran.
** The Kahu and Kewa birds were considered non-canon for some years because of legal issues surrounding their names. They were replaced in-story by Gukko birds who were retconned into their places. Later, they accepted them back into canon, with the explanation that they're a subspecies within the Gukko. Thus, technically, it still can be said that the Gukko have been there all along.
* This is essentially what a marriage annulment amounts to. In a divorce, a marriage is officially declared to be over; when a marriage is annulled, however, it is considered never to have been a valid marriage in the first place. In times when divorces were significantly harder to get, many people would find a reason for an annulment. The annulment/divorce distinction is a specific manifestation of a greater issue in contract law: some contracts can be declared void, i.e., considered to have never been formed, for reasons such as misrepresentation, one party being a minor who did not get adult consent, among other things, while other contracts are "voidable"—they were valid contracts up to a point where one party's behavior rendered them void.
* Coca-Cola's official history at its website doesn't mention New Coke at all. Nor does its corporate museum.
* When former assistant football coach Jerry Sandusky was arrested on charges of sexually molesting teenage boys, students at Penn State painted him out of a mural showing all the present and past coaches of the football team, replacing him with a blue ribbon. Even moreso, the NCAA erased '''every''' Penn State football victory from 1998-2011 as part of the punishment for covering up the scandal for so long.
* Neither Benedict Arnold's name nor face appear on memorials to him at the site of the Battle of Saratoga or on the formal roll of past commandants of West Point at the U.S. Military Academy (only the date, 1780, appears where his name would be), since despite real military accomplishments that twice saved the Continental Army's bacon during the Revolutionary War, he's remembered today primarily for [[TheQuisling selling out to the British]] (and specifically, was going to hand over West Point to the enemy, until UsefulNotes/GeorgeWashington found out about the plot).
* From 1912 to 1948 the OlympicGames used to feature art competitions which was considered official and with their own medals. Now the IOC considered those events unofficial and the medals won aren't included in the IOC official database.
* An amendment to the U.S. Constitution can become this in the legal system if and only if another amendment passes that repeals it. So far this has happened with the 18th Amendment (which banned alcohol), which was repealed by the 21st Amendment. Congress has attempted this to the Eleventh Amendment, on the basis of the Fourteenth Amendment (Part V, giving Congress the power to enforce the amendment with appropriate legislation), but the US Supreme Court struck this down in Copyright Law.
* Any part of the Constitution can become this, not just amendments. In fact the whole point of amendments, really, is to have this option to rewrite part of the Constitution if need be. For example, U.S. senators were originally elected by the state legislatures (as specified in Article 1), but that was changed in 1913 to direct popular vote by the 17th Amendment.
* The Articles of Confederation are this to the American government as a whole. Early Americans' fear of centralized government were borne true in the Articles, and the interstate squabbling that entailed caused it to fail. The Constitution replaced it, with a stronger central government.
* After Melky Cabrera was supposed for Performance-Enhancing Drugs, the San Francisco Giants acted like he didn't exist, excluding him from the postseason roster and even not giving him a World Series ring. Similarly, Lance Armstrong's 7 Tour de France titles were stripped after he was found to have [=PEDs=].
* The University of Nebraska-Lincoln football program holds the [=NCAA=] record for most consecutive home-game sellouts (the streak started in 1962). When the university celebrated the 300th consecutive sellout game in September 2009, they very carefully did ''not'' invite former athletic director Steve Pederson or former head coach Bill Callahan, the two men "credited" with almost ruining the football program and bringing the streak to an end.
* This is what the Incognito Mode or Private Browsing mode does to a Web browser's history when activated.
* Model railroading generally ignores the fact of segregation in a large portion of the United States during the first six decades or so of the 20th century; drawings of stations with separate "colored" waiting rooms understandably do not label them as such, but the reason for multiple waiting rooms is not given; and while "Jim Crow" coaches and combines (passenger cars with a section for baggage or freight) with separate sections for "white" and "colored" passengers are sometimes mentioned and seen in photographs, plans for such cars rarely appear and the cars are not commonly modeled. Also, if you want people of color on your layout, you'll probably have to paint the figures yourself (it's a blind spot among manufacturers, not prejudice). This despite the current passion for realism in the hobby.
* Dodge ran a series of ads highlighting their history, culminating in a [[https://www.youtube.com/watch?v=Oicu39lda0E 100th anniversary video]] showing the evolution of the brand. It completely skips over the [[TheEighties 1980s]] up til TheNewTens, as for the most part the company sold nothing but [[TheAllegedCar cars built by idiots]], [[PaletteSwap rebadged Mitsubishis or Mercedes]], or just plain [[CantCatchUp outdated vehicles]] following their nigh-bankruptcy during the Oil Crisis, all the way until FIAT bought them in 2010.

[[folder:Professional Wrestling]]
* After June Byers shot on Mildred Burke and won the Wrestling/NationalWrestlingAlliance World Women's Championship, Burke refused to accept that she lost the belt since the match was called at one fall instead of the usual two out of three and she had merely [[ILetYouWin conceded the first fall]] to get some breathing room and beat Byers in the next two. So she came up with her own belt in her own promotion, the WWWA, which broke away from the NWA and acted as if she had been holding it for the last 17 years.
* The members of the NWA refused to acknowledge the Fabulous Moolah's first reign as the World Woman's Champion. In defiance of this, the World Wrestling Federation decided Moolah's first title reign had not ended, not for twenty eight years anyway.
* Wrestling/BoboBrazil never beat Wrestling/BuddyRogers for the NWA World Heavyweight Championship, so says the NWA. Carlos Colon never held the belt either! This would actually become a plot point in Wrestling/{{TNA}}, back when it was under the NWA banner. Wrestling/RonKillings correctly pointing out the NWA refused to acknowledge any black men as World Heavyweight Champion.
* RealLife example: According to the "official" WWE title history, Wrestling/BobBacklund defeated Wrestling/SuperstarBillyGraham for the WWWF Championship in February 1978, and lost it to Wrestling/TheIronSheik in December 1983. However, in November 1979, at a cross-promotional show in Japan, Wrestling/AntonioInoki defeated Backlund cleanly for the title, and was announced and promoted at NWF (National Wrestling Federation, a subsidiary of the NWA) shows as being the WWWF Champion. Since the WWWF never authorized this title change, they never acknowledged Inoki as being their first (and, discounting the Pacific-Islander Wrestling/{{Yokozuna}} only) Asian world champion.
* The Rockers won the WWF Tag-Team Championship from the Hart Foundation on the November 23, 1990 edition of ''The Main Event''. However, due to a ring rope malfunction during the match in the second fall, the title change was stricken. The Rockers never won the titles again.
* Wrestling/KazushiSakuraba's first fight in 1996 against Rene Rooze is not recognized by most mixed martial arts organizations because even though it was not a cooperated match, many feel the rules were too much like pro wrestling to count.
* After Wrestling/{{ECW}} betrayed the Wrestling/NationalWrestlingAlliance, the NWA stripped Wrestling/ShaneDouglas of their World Heavyweight Championship and leaned on Wrestling/SmokeyMountainWrestling, who put the belt on Wrestling/ChrisCandido. After the NWA got back on its feet though, it disregarded Candido's reign in favor of Dan The Beast Severn.
* Wrestling/NewJapanProWrestling really didn't like how Wrestling/{{WCW}} had [[Wrestling/JushinThunderLiger Jushin Liger]] drop their junior heavyweight championship and maintained that he held the belt his entire time in WCW.
* Naturally, all victories Wrestling/TommyDreamer may have scored over Wrestling/{{Raven}} had to be ignored for their feud in Wrestling/{{ECW}} to work. Dreamer was finally able to get an acknowledged win over Raven when Raven went back to WCW though.
* Kayfabe example: on the April 17, 2000 edition of ''Raw'', Wrestling/ChrisJericho upset Wrestling/TripleH and won the WWF Championship, but Triple H - then running the show alongside his wife [[Wrestling/StephanieMcMahon Stephanie [=McMahon=]]] - [[FalseReassurance promised referee Earl Hebner that he would never touch him again while he was under contract if he reversed the decision.]] Hebner did just that, turning the WWF Championship back over to Trips and striking the match from the records; Trips rewarded Hebner by firing him and nailing the Pedigree. To this day, the official WWE records don't acknowledge Jericho's victory on that night.
* Thanks to the ruling regarding the World Wide Fund for Nature, the WWE had to retcon '''everything''' from before the WWF-to-WWE change to say "WWE". Except in Europe, oddly. And they still do this when writing or talking about said era(s), but on the footage itself, all WWF logos and utterances are legal again.
* Do you remember the time Wrestling/ReyMysterioJr was unmasked in Wrestling/{{WCW}}? Wrestling/{{WWE}} doesn't. This is probably for the best, though, as most feel he should have never been unmasked to begin with. Normally the commission wouldn't have allowed this and would have demanded that Rey stay unmasked, but considering the disrespectful manner of his unmasking and the fact that they hated what Wrestling/EricBischoff did, they allowed him to stay masked. The {{loophole|Abuse}} used to justify this is to claim that because Rey no longer includes "Jr" in his ring name, he's actually now portraying his uncle's character, despite being smaller and having a different wrestling style than his uncle.
* Keiji Sakoda and Wrestling/SamoaJoe were the first NWA Intercontinental {{Tag Team}} Champions, well that's what everyone except for Wrestling/ProWrestlingZero1 says anyway. As far as Zero 1 is concerned, they never held the belts.
* WWE decided to ignore the fact [[Wrestling/TheWorldsGreatestTagTeam Shelton Benjamin]] had trained Wrestling/BrockLesnar in college and served as his tag team partner in the Minnesota Stretching Crew, instead saying Benjamin had been Lesnar's roommate before doing away with any personal connection between them altogether. Though they eventually started acknowledging reality again on their website.
* Wrestling/{{Kane}}'s (kayfabe) marriage to Wrestling/{{Lita}} had to be retconned due to the Wrestling/MattHardy[=/=]Lita[=/=]Wrestling/{{Edge}} debacle. They moved it back into continuity later, and the ''latter'' was retconned (mostly) due to Matt's release and subsequent blackballing from the company.
* NWA Midwest disputed the result of the three way dance Wrestling/MsChif and Wrestling/DaizeeHaze lost to Mickie Knuckles at an IWA Mid-South event and declared MsChif was the champion up until she and Diabolic Khaos partner [[Wrestling/HunterJohnston Delirious]] lost a winner takes all match to Daizee Haze and Wrestling/MattSydal. After [=MsChif=] beat Josie to regain the belt, NWA Midwest renamed it the Zero1-Midwest Women's championship, declaring [=MsChif=] had been the ''only'' person to hold it up till that point.
* Wrestling/ChrisBenoit [[UnPerson never wrestled]], so all accomplishments are disregarded including his Wrestling/RoyalRumble win and title victory at Wrestling/WrestleMania XX.

[[folder:Tabletop Games]]
* Fans of ''TabletopGame/{{Paranoia}}'' like to pretend that the much-maligned Fifth Edition doesn't exist. In fact, the writers of a later edition (Paranoia XP from Mongoose Publishing) have declared the Fifth Edition an "[[UnPerson un-product]]" (rather appropriate for a darkly humorous game about a dystopia). The also-maligned Crash Era near the end of Second Edition also officially "never happened".
* When White Wolf screwed up with the ''TabletopGame/OldWorldOfDarkness'', they'd often try to correct the biggest disasters by destroying all involved and making sure they would not rise from the ashes. Examples:
** ''Dirty Secrets of the Black Hand'' for ''TabletopGame/VampireTheMasquerade'', which "revealed" that most vampires were possessed by evil spirits, and featured a "liberated" group called the True Black Hand that fought against them. By the time Third Edition came up, said group was wiped out entirely after it was revealed that they'd gotten everything wrong.
** Samuel Haight started off as a villainous {{N|onPlayerCharacter}}PC for ''TabletopGame/WerewolfTheApocalypse'', a disgruntled Kinfolk who ended up killing five werewolves so that he could become one in a blasphemous ritual. This was good. Then he got his hands on an artifact that let him use Awakened magic. This was bad. Then he became a ghoul and started learning vampiric Disciplines. This was worse. Finally, a book came out devoted entirely to killing him, and the minute his soul arrived in the afterlife, it was taken and forged into an ashtray by [[ContinuitySnarl Rasputin]].
** In first edition ''WOD'', a vampire could make other vampires of both animals and werewolves. Second edition ''WOD'' plainly admits that the former ("vampire dogs") is stupid and the latter hybrid [[{{Munchkin}} overpowered]], so disallows both.
* Over in the ''TabletopGame/NewWorldOfDarkness'' on the other hand...
** In ''TabletopGame/VampireTheRequiem'' 1e, vampires were ImmuneToBullets (shooting damage downgrades to Bashing), but for some reason the same reasons why didn't prevent them from taking full Lethal damage from swords, spears, etc. In 2e, having realised that this was part of the same absurdity that led to just about everyone in the [=OWoD=] toting katanas and swords all the time, all weapons damage was downgraded, making the Damned just generally MadeOfIron.
** In ''TabletopGame/WerewolfTheForsaken'' 1e, werewolves were forbidden from mating with each other because, unlike in ''TabletopGame/WerewolfTheApocalypse'', the result would not be a Metis[[note]]deformed shapeshifter permanently stuck in the most powerful of the forms[[/note]], but an Unihar, a "spirit wolf" -- an irredeemably evil spiritual FetusTerrible that would do its damndest to kill all werewolves upon coming to term. Having realised the UnfortunateImplications of this, 2e quietly dropped them, and made it that a werewolf/werewolf coupling only produces a particularly strong wolfblood.
* ''TabletopGame/{{GURPS}} TabletopGame/{{Traveller}}'' disavows the Rebellion (from ''[=MegaTraveller=]'') and the Virus (from ''[[JumpTheShark Traveller: The New Era]]''), portraying itself as an "alternate history" from ''TabletopGame/{{Traveller}}''. Other ''TabletopGame/{{Traveller}}'' products keep the Rebellion and ditch the Virus, or keep both (fans and players are similarly split; see BrokenBase).
* ''TabletopGame/DungeonsAndDragons'':
** Writers for TSR went so far as to mention explicitly in a reboot continuity guide for the ''World of TabletopGame/{{Greyhawk}}'' campaign setting that ''Greyhawk Ruins'' was to be considered the [[WordOfGod official]] version of Castle Greyhawk and not the [[DudeNotFunny pretty dated and unfunny]] parody module ''Castle Greyhawk''.
** ALL of the ''TabletopGame/{{Eberron}}'' {{Tie In Novel}}s are considered non-canon.
** The TabletopGame/{{Ravenloft}} novel ''Lord of the Necropolis'' has been sealed in the earth below canonicity with an Imprison spell for revealing the nature of the Dark Powers, which is a thing you are really, really not allowed to do.
* ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'':
** Because no one's entirely sure if the Chaos God Malal is owned by Games Workshop or the comic book author who introduced him to the franchise, GW dropped all mention of him from their gamebooks to be on the safe side. He still gets a few references; for example there's a Chaos Space Marine warband called "Sons of Malice" that wears Malal's colours, the rulebook for the spinoff game ''Inquisitor'' includes a weapon very similar to the ones champions of Malal use in the list of daemon weapons, and he appears in one of the short story collections GW released, though he is know as "Malice" there.
** The [[OurDwarvesAreAllTheSame Squats]] have been stricken from all records, partly due to a shift towards a [[ShooOutTheClowns "more serious"]] direction, partly because their attempted army book became an absolute mess after pre-production. For a while it was established canon that they ''did'' exist, but only just long enough to be entirely eaten by [[HordeOfAlienLocusts Tyranids]]. Then the Squats came back, but recognized as a type of abhuman rather than a distinct race.
** By the third edition, the Star Child and attendant background elements introduced in Slaves to Darkness had been officially stricken, with a note in the corebook that the "Star Child cult" was a minor Tzeentchian cult that had been obliterated.
** The Fimir got almost entirely excised from the canon, because there weren't any female Fimir and they could only reproduce through... well, {{rape|AsDrama}}. They've slowly been reintroduced through Forge World and references in the 8th edition Rulebook, but are substantially different.
* ''TabletopGame/MagicTheGathering''. Karona meeting [[BigBad Yawgmoth]], apparently still alive, in the ''Scourge'' novel has been {{retcon}}ned as having been an impostor. Or it could have been a {{Psychic Dream|sForEveryone}} of the past.
* ''TabletopGame/{{Exalted}}'':
** Scroll of the Monk is a much-maligned product and OldShame of writer Dean Shomshak. The [[PromotedFanboy Ink Monkeys]] have gone on record as saying it does not exist beyond an example of not reading the rules before making a book.
** Zeal was widely panned before Errata Team Prime finally canned it.
** Even the most vocal of the current writers and editors are of the opinion that the first 2-4 chapters of ''Manual of Exalted Power: Infernals'' should not be read, discussed beyond variations on "it's awful", or used in character backstories.
** According to a leaked job application for the ''Third Edition'' team, all of Second Edition is this.
* ''TabletopGame/{{Shadowrun}}'':
** Many of the earlier novels. Before the 2nd Edition, when the game really found its voice, Shadowrun was portrayed very much as ''Tabletopgame/DungeonsAndDragons'' [[RecycledInSpace/TabletopGames In The Future (!!!)]], with a heavy emphasis on bizarre creatures, cyborgs, mad science, and otherworldly spirits. This led to such things as characters somehow rising from the dead, invasions by {{Eldritch Abomination}}s across the planes, and ''(especially)'' a dying corporate [=CEO=] having his brain implanted into a glorified tumor in a jar, communicating via Matrix hookup. Nothing is ever declared non-canon, per se, but whenever a sourcebook finds itself having to cover material from this earlier era, the Shadowland commentators make a note to remark on just how utterly bizarre these events and creatures are, many thinking them to be just hoaxes or exaggerations.
** In the novels, Dunkelzahn's death was a [[spoiler:HeroicSacrifice meant to help his agents prevent a premature invasion of Earth by the Horrors because of a side effect of the Great Ghost Dance]]. But in all subsequent sourcebooks, this aspect of the event is rarely touched upon, with Dunkelzahn's death being an assassination by unknown parties. One of the exceptions was in ''Harlequin's Back'', [[spoiler:where the players have to fix the aforementioned side effect]], and the prologue implies that Dukelzahn is, on some level, the one setting it into motion. This ''still'' fits in the continuity of the game, technically, as only maybe ''two'' people know what really happened to Dunkelzahn (Harlequin is one of them, and even he's not entirely sure). As far as everyone else in the world is concerned, it really ''was'' an assassination by unknown parties.

[[folder:Video Games]]
* ''VideoGame/EpicMickey'' deliberately ignores the fact that WesternAnimation/OswaldTheLuckyRabbit still appeared in cartoons for many years after Disney lost him. This may be justified as the Disney and Lantz Oswald are treated as two separate characters, but there isn't even an implication given that Ozzie starred in more shorts after Walt lost him.
* Satoru Iwata declared that the true "current" state of the ''VideoGame/StarFox'' series is either after ''VideoGame/StarFoxAssault'' or somewhere before ''VideoGame/StarFoxCommand''. More than likely to be the former than the latter, if current information is any credible, as whilst the appearances of the cast in ''[[VideoGame/SuperSmashBros Super Smash Bros. Brawl]]'' do make some '''slight''' reference of certain of Command's plotlines, they otherwise seem to resemble and behave like their appearances in ''Assault'' far more. Specifically, [[OfficialCouple Fox McCloud and Krystal's]] [[ItsNotYouItsMyEnemies relationship]] [[WomanScorned problems]] from ''Command'' are alluded to in their profiles, but otherwise they're still together and Krystal is still a member of Star Fox (as opposed to joining [[FaceHeelTurn Star Wolf]]), Panther Caruso does not [[ThirdPersonPerson speak in third-person]] and the ships are all pre-''Command''.
* Epic has admitted that ''Unreal Tournament 2003'' isn't a complete game, first by refining the original game into ''VideoGame/UnrealTournament2004'' with many of the previously missing features and offering a rebate to ''2003'' owners who bought ''2004'', then by numbering the sequel ''VideoGame/UnrealTournamentIII''. Strangely enough, the backstory of ''2004'' doesn't override that of ''2003'', claiming that every event of ''2003'' happened (such as Malcolm being defeated by Gorge). The same can't be said for the original ''Unreal Championship'', which was set in an AlternateUniverse.
* After Singletrac died, 989 Studios took over the ''VideoGame/TwistedMetal'' series and produced ''Twisted Metal 3'' and ''4'' on [=PlayStation=]. Once Incognito Entertainment (a studio consisting largely of Singletrac employees) regained the rights to the series, they made ''Twisted Metal Black'', which was much DarkerAndEdgier than the original two games and set in its own continuity. The only {{P|layStationPortable}}SP entry in the franchise, ''Head-On'', is set after the second game and ignores the 989 entries. The post-989 entries were much better received, to the point that ''Head-On'' is considered by fans to be the "true" ''Twisted Metal 3''.
* All the ''Franchise/{{Castlevania}}'' games (barring the parody game ''VideoGame/KidDracula'') were part of the canon in some form or another until Koji Igarashi (the director of ''VideoGame/CastlevaniaSymphonyOfTheNight'') took over the series as producer during the development of ''VideoGame/CastlevaniaHarmonyOfDissonance'', removing the two {{Nintendo 64}} installments, ''[[VideoGame/CastlevaniaLegends Legends]]'', and ''[[VideoGame/CastlevaniaCircleOfTheMoon Circle of the Moon]]'' from the official timeline. Igarashi clarified that the [=N64=] games and ''Circle of the Moon'' were still canonical, but were demoted to "side-story" status. ''Legends'' on the other hand, was officially retconned out of the series' continuity and is regarded as an alternate universe story.
* Creator/{{Capcom}} has all but said that ''VideoGame/DevilMayCry 2'' doesn't exist - for instance, Dante is a playable character in ''VideoGame/ViewtifulJoe'' [[RuleOfFunny for comedic reasons]], and he ''outright says'' "I don't remember that" when Alastor references the events of ''Devil May Cry 2''. The ''Viewtiful Joe'' appearance also jokingly puts forth the idea that the "Dante" in ''[=DMC2=]'' is actually a friend of Dante's named Enzo, who had been [[IdentityImpersonator impersonating him for some reason]], explaining his decidedly OutOfCharacter behavior. Trish smugly asks Dante if Enzo has [[MuggedForDisguise stolen his clothes again]].
* The novel ''VideoGame/{{Crysis}}: Legion'' has been completely rendered non-canon by the events of ''Crysis 3''. Unfortunately this means that quite a few plot holes closed by the novelization have been opened back up again.
* ''VideoGame/{{Fallout}}'':
** This happened to both a good chunk of ''VideoGame/{{Fallout 2}}'' and almost all of ''VideoGame/{{Fallout Tactics|BrotherhoodOfSteel}}''. The former for the reasons stated below, the latter because many of the elements contradict [[VideoGame/{{Fallout1}} the original game]] and its backstory. On the other hand, Bethesda seems to have the position that it's valid if it doesn't contradict anything, in relation to ''2'', and events are canon, [[BroadStrokes details are not]], regarding ''Tactics''. Specifically, when asked about Super Mutants, a Brotherhood Scribe lists fighting them on the West Coast and then near Chicago. Interplay and Black Isle had also dismissed them soon after release, and [[WordOfGod the tattered remnants of the dev team contributing to the Fallout Bible]] continue to do so.
** ''VideoGame/FalloutBrotherhoodOfSteel'', however, is completely exiled from continuity.
** The original ending of ''VideoGame/{{Fallout 3}}'' was...vastly unpopular, to say the least ([[spoiler:the player is forced to flip a switch that will save the day but also douse them with lethal amounts of radiation. Any companions that are immune to radiation will simply refuse to do it for you.]]). The ''Broken Steel'' {{D|ownloadableContent}}LC fixes that by [[spoiler: allowing a companion to flip the switch, or the player do it themselves but be put in a coma for two weeks.]]
** Chris Avellone, one of the head writers for ''Fallout 2'', created a series of [[http://fallout.wikia.com/wiki/Fallout_Bible Fallout Bible]] posts which made a good portion of the game, particularly the overwhelming number of [[ShoutOut cheesy pop-culture references]], non-canon. Nearly ''everything'' that happened in the town of Broken Hills is non-canon.
** ''VideoGame/FalloutNewVegas'' however is full of nods to both ''Fallout 2'' and ''VideoGame/FalloutVanBuren'', the game that would have been ''Fallout 3''. Its ''Old World Blues'' DLC is also partly based on content that was cut from ''Fallout 2''.
* On the subject of Bethesda, suddenly realizing that multiple endings of [[VideoGame/TheElderScrollsIIDaggerfall the second game]] in ''Franchise/TheElderScrolls'' series would have been a great idea for the end of a series, they averted this trope fully by declaring all ''six'' endings canon. It's now listed in canon as the Warp in the West (an ''in-universe'' MindScrew), transforming 44 quarreling city-states into five loyal countries literally overnight.
* In the late '90s, Creator/{{Konami}} farmed out the development of two ''VideoGame/{{Contra}}'' sequels to Hungarian developer Appaloosa (best known for the ''VideoGame/EccoTheDolphin'' series), who produced ''Contra: Legacy of War'' for the PS and Saturn in 1996, and ''C: The Contra Adventure'' for the PS in 1998. Neither was that well-received by fans and critics alike. In fact, Konami even canceled plans to release a Japanese version of ''Legacy of War''. In 2002, Konami commissioned Nobuya Nakazato (director of ''Contra III'' and ''Hard Corps'') to develop the [=PS2=] sequel, ''Contra: Shattered Soldier''. The unlockable timeline of the game mentions all of the past ''Contra'' games, with the notable omissions of ''Legacy of War'' and ''Contra Adventure'' (and ''Contra Force'', which was just a DolledUpInstallment to begin with). On a related note, the Japanese and American versions of the series had their separate continuities prior to ''Shattered Soldier''. In Japan, the series always took place in the distant future, but in America the early games in the series (namely ''Contra'', ''Super C'' and ''Operation C'') had their plots rewritten so that they took place in the then-present. As a result, when they retained the future setting for ''Contra III'', the changed the identities of the two heroes from Bill and Lance to their descendants Jimbo and Sully. With ''Shattered Soldier'', Konami ignored the continuity of the previous American localizations and followed the original Japanese plot more closely.
* ''Franchise/MetalGear'':
** When the NES port of ''VideoGame/MetalGear'' proved to be successful, Konami commissioned one of their teams to develop a sequel for the American and European market titled ''VideoGame/SnakesRevenge''. This sequel was made without Creator/HideoKojima's involvement and when he was told about it, he decided to make his own sequel for the Japanese [=MSX2=] titled ''VideoGame/MetalGear2SolidSnake''. The ''VideoGame/MetalGearSolid'' games follows the storyline from ''Metal Gear 2'' rather than ''Snake's Revenge''.
** The PSP game ''VideoGame/MetalGearSolidPeaceWalker'' serves as the direct sequel to ''VideoGame/MetalGearSolid3SnakeEater'', completely disregarding the previous PSP game in the series, ''VideoGame/MetalGearSolidPortableOps'' (which Kojima did not direct), aside from a single {{discontinuity nod}}. The ''Metal Gear'' timeline from Kojima Productions omits ''MPO'', showing only seven canonical entries (the two [=MSX2=] games, ''[=MGS1=]'' through ''4'' and ''Peace Walker'').
* Creator/MonolithProductions chose to [[http://www.projectorigincommunity.com/forum/showpost.php?p=5928&postcount=7 ignore]] the two ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R.]]'' {{Expansion Pack}}s (which were made by a different company) when they started development on the game's ''real'' sequel. Some elements from the expansions were kept in the sequel, however, such as the Replica reactivating despite Fettel's death (though this time with an actual logical explanation, at least for the first group of them), [[spoiler:Fettel coming back from said death]], and [[ArsonMurderAndJaywalking the ability to punch doors open]].
* The official position of Creator/{{Valve|Software}} is that the ''VideoGame/HalfLife1'' addons ''Opposing Force'' and ''Blue Shift'' are not addressed in ''VideoGame/HalfLife2'', its addons, and future sequels. The name of Barney Calhoun and his background as a security guard in Black Mesa were taken from ''Blue Shift'' and incorporated into ''Half-Life 2'', but since all ''Half-Life'' protagonists are {{Heroic Mime}}s and he never mentions any of the events or other characters from ''Blue Shift'' later on, it doesn't actually confirm that it did happen in the official continuity. Valve does, however, seem to consider ''Opposing Force'' canon from they way they've talked about protagonist Adrian Shepard.
* ''{{Franchise/Halo}}'''s continuity policy directly addresses this; new material automatically overrides old material in the event of a contradiction, while the games override the [[ExpandedUniverse books]], which in turn override promotional materials like the "Believe" ad campaign. Thus, the claims in the older books that Elites, Brutes, and Hunters were never encountered until the last year of the Human-Covenant war were overridden by newer material (and updated reprints of said older books) which had them fighting in the war from the very beginning.
* ''VideoGame/{{Myst}}'' is a little more complicated, as it involves multiple LiteraryAgentHypothesis. The first two books (Atrus, Catherine) do not mention the D'ni society as having slaves, just a caste system. Book of D'ni makes it explicit that slavery is repugnant to D'ni society. Then ''VideoGame/{{Uru}}'' came out, with the storyline's finale in ''VideoGame/MystVEndOfAges''... Again, it seems the author of the books "based" his writings on Catherine's journals, which dismiss the clear slavery of the Bahro, for never entirely cleared reasons. As for Book of D'ni, well, people long gave up making sense of it. And then there's ''Pyst'', which shows how the first game's locations have been overrun by commercialization (and subsequently abandoned), but that was an outright parody.
* Nintendo has outright stated that ''VideoGame/TheLegendOfZeldaCDiGames'' never happened (and not just because Nintendo doesn't own the rights to them). This is taken to such an extreme that an issue of ''Magazine/NintendoPower'' describes ''VideoGame/TheLegendOfZeldaSpiritTracks'' as the first time Zelda is a (semi)playable character. She was fully playable in two CD-i games. The official ''Hyrule Historia'', which gives the official timeline of the games, also omits them.
* ''Franchise/SuperMarioBros'':
** ''VideoGame/HotelMario'' for the CD-i is disregarded by fans, critics and Nintendo developers alike.
** The premise of ''VideoGame/SuperMarioBros2'', with its AllJustADream ending, has been entirely ignored by the Mario canon, since all of its supposedly "wacky dream characters" (who weren't ''Mario'' characters at the time, see ''VideoGame/DokiDokiPanic'') have since been shown to be residents of the normal ''Mario'' universe.
* When British game publisher U.S. Gold got the license to produce ports of ''VideoGame/{{Strider}}'' for home computers in Europe, they took the liberty of producing an exclusive-sequel titled ''Strider II'', which was later remade for the SegaGenesis and GameGear and released in America under the title of ''Journey From Darkness: Strider Returns''. Capcom later got to make an arcade/PS sequel titled ''Strider 2'', which completely ignored U.S. Gold's own sequel.
* In the first ''VideoGame/GodOfWar'' game, in an unlockable video [[spoiler:the protagonist, Kratos, visits his mother and learns that Zeus was his father. He's not happy to learn this, and plans to take vengeance on Zeus somewhere along the line]]. Yet in the second game, [[spoiler:as Kratos is holding a dying Athena, Athena reveals to him that he is Zeus' son, which Kratos is surprised to hear, but declares that he "has no father"]]. The director of the game acknowledged this error in the extras, and states that he was disappointed that they revealed it in the first game, because he finds it more fitting for it to be dropped on Kratos after he is denied his vengeance. He openly said that he doesn't care about the error.
* The creators of the ''VideoGame/StarControl'' series have made it clear that ''Star Control 3'', which was made without their input and was met with overwhelming fan backlash, never happened. So no, the Precursors [[spoiler:aren't cows]]. WordOfGod ''has'' revealed that some of the things in it ''are'' what the creators had intended to do if they'd gotten to make their own sequel, though - such as the part about the Mycon actually being biological terraformers created by the Precursors whose programming has become distorted into a bizarre religion.
* The ''VideoGame/UltimateSpiderMan'' game was initially touted as being 100 percent canon [[Comicbook/UltimateSpiderMan in the comic book continuity]]. Unfortunately, the comic eventually moved in a direction that made it flat out impossible to treat the game as canon, so Creator/BrianBendis ended up writing a BroadStrokes PragmaticAdaptation that imported the most relevant bits of the game, while roundly ignoring the elements that didn't fit.
* '' VideoGame/WorldOfWarcraft'':
** Most of what is said in the ''Warcraft'' tabletop game is ignored, especially considering Whitewolf and Creator/BlizzardEntertainment broke off ties.
** Any time something happens in ''[=WoW=]'' that directly contradicts established canon in the RTS games, ''[=WoW=]'' takes precedence, often stated as being "ongoing shifts in artistic leaning" or the like. [[SuspiciouslySpecificDenial Certainly not because they just forgot the old story and never went back to check on it before finalizing the new info.]] See: the ''entire backstory'' of the Draenei: Originally, the Eredar were one of the races that corrupted Sargeras and the Dranei were an unrelated species native to the Ork homeworld of Draenor; now, Sargeras was already corrupted by the Nathrezim by the time he got to them, and ''he'' corrupted ''them'', with the Draenei being that faction of the Eredar who resisted his corruption and fled to Draenor.
* A rather odd case for Banpresto's ''VideoGame/SuperRobotWarsOriginalGeneration''. ''Original Generation'' ([=OG1=]) lets players choose between [[VideoGame/ShinSuperRobotWars Ryusei Date]] and [[VideoGame/SuperRobotWarsCompact2 Kyosuke Nanbu]], whose stories co-exist with one another for the first half of the game. It's only until the second half events unfold differently for either character. Come ''Original Generation 2'' ([=OG2=]), events state only Ryusei's second half of [=OG1=] happened; Kyosuke's second half is never mentioned at all. While this drops loads of {{foreshadowing}} from Kyosuke's second half of [=OG1=], fans were quick enough to deduce Banpresto did this to show that [=OG1=] was never meant to be played in favour for Kyosuke, but the sequel was, since the game was primarily focused on his story from ''[[VideoGame/SuperRobotWarsCompact2 Super Robot Wars Impact]]''. Strangely enough, Kai Kitamura seems to know the other members of the cast very well, even though he's a permanent character in Kyosuke's route. And to celebrate SRW's 15th anniversary, Banpresto released ''Original Generations'' ([=OGs=]), a VideoGameRemake on the PlayStation2 of both GBA games, which rehashes the storyline to include {{Early Bird Cameo}}s, new HumongousMecha, the cast of ''VideoGame/SuperRobotWarsReversal'', new characters and a major personality change to [[VideoGame/SuperRobotWarsAdvance Axel Almer]].
* Oddest case ever: ''VideoGame/LeisureSuitLarry 4''. It doesn't exist. It's not just non-canon, [[UnInstallment it was never made]]. The real-life explanation is that they couldn't think of a good way to continue from ''Larry 3''[='s=] happy ending, so they just did a sequel anyway and made the continuity errors it produces part of the plot. The story goes that creator Al Lowe had sworn that there would never be a ''4''... before agreeing to make another ''Larry'' game. To keep his oath, he made ''5'' and simply had the characters reference ''Leisure Suit Larry 4: The Missing Floppies'', a title that exists in the game's plot. The cleanup for the plot from ''3'' was an added bonus. The lack of ''4'' even became a plot point in ''VideoGame/SpaceQuest 4''; Vohaul had corrupted the master disks and used them to take over Xenon.
* Another Creator/{{Sierra}} example is that the widely-derided ''VideoGame/KingsQuestMaskOfEternity'' has never shown up on any of the compilation [=CDs=] of the series and has only since been re-released on [[Website/GOGDotCom GOG.com]].
* ''Franchise/SonicTheHedgehog'':
** After a [[spoiler:[[DamselScrappy whiny princess]] [[InterspeciesRomance kissed a hedgehog back to life]]]] in ''VideoGame/SonicTheHedgehog2006'', the entire game erased itself from continuity via [[ResetButton temporal retcon]]. A bit HilariousInHindsight, too: after firing the writers, SEGA wisely decided to pretend '''the entire game''' never happened, as well. This is made confusing because, despite the game being ''ERASED FROM TIME'', Crisis City still appears in ''Sonic Generations''! And Sega has yet to comment.
** ''VideoGame/KnucklesChaotix'' has been written out of canon by the Chaotix team's ''VideoGame/SonicHeroes'' portrayals, referenced in ''VideoGame/SonicGenerations'' where a poster with Mighty on it says he was last seen in [[VideoGame/SegaSonicTheHedgehog 1993]]. Mighty fans haven't taken this very well. Presumably this would also apply to ''VideoGame/SonicTheFighters'' for its pre-Heroes inclusion of Espio (not to mention the plot including an eighth Chaos Emerald), but characters introduced in the game have since made cameos in ''VideoGame/SonicGenerations'' posters just like Mighty.
* ''VideoGame/LegendOfMana'' is now not considered by Creator/SquareEnix to be part of the main ''VideoGame/WorldOfMana'' continuity.
* The first five ''VideoGame/{{Touhou}}'' games for the PC-98 exist in a weird state where they're not ''completely'' discontinuity, but enough for that status to be widely accepted. The following games for Windows make very few references to the PC-98 games, and what little that carried over is greatly changed. [[WordOfGod ZUN himself]], when questioned, only says that we could ignore the PC-98 games instead of saying anything stronger.
* ''VisualNovel/RadicalDreamers'', the text-based (and [[NoExportForYou Japan-only]]) first sequel to ''VideoGame/ChronoTrigger'', was completely thrown out of continuity by the later PS sequel ''VideoGame/ChronoCross'', which was also something of a remake of ''Radical Dreamers''. The events of that game are thrown into an alternate reality...[[MindScrew or something]]. Series creator Masato Kato originally had much greater plans for ''Dreamers'', but the entire game was rushed. ''Cross'' was his way of finishing off his original planned story.[[spoiler:..and the characters of ''Trigger'', while he was at it.]]
* In a cross-medium example, all ''Franchise/AlienVsPredator'' games seem to ignore the existence of ''Film/AlienResurrection'' by depicting xenomorph encounters, Weyland-Yutani xenomorph research facilities, and at least two completely infested planets known to Company executives at a time when the species is supposed to be extinct in known space. The latest game, however, acknowledges one of the ''Alien vs. Predator'' films; however, it ignores all previous games.
* While not entirely declaring them non-canon, Yoshio Sakamoto said that he did not take the plots of the ''VideoGame/MetroidPrime'' games into consideration in the making of ''VideoGame/MetroidOtherM''. This leads to some weirdness when Samus mentions that this is the first time she's undertaken a mission alongside the Federation when she already did that in ''Metroid Prime 3''. However, these are minor plot holes in a series riddled with them. The fact that the ''Prime'' sub-series was American-made and [[GaidenGame told its own story instead of furthering the plot]] of the Japanese games may have had something to do with this.
* In 1993, Creator/{{Falcom}} commissioned two separate companies to developed their own versions of the fourth ''VideoGame/{{Ys}}'' game. ''Ys IV: Mask of the Sun'' was released by Tonkin House for the Super Famicom, while ''Ys IV: The Dawn of Ys'' was released by Creator/HudsonSoft for the PCEngine Super CD (a third version was also planned for the MegaDrive, but it was never released). ''Ys V'' was later developed by Falcom and exclusively for the SFC, and all the later ''Ys'' sequels followed the SFC games. The 2005 PS2 remake of ''Ys IV'' was even based on the SFC version.
* ''VideoGame/BombermanActZero'' is not a part of the main ''Bomberman'' continuity, both on account of it being [[DarkerAndEdgier a radical departure from the series' light-hearted mood]] and from it being a rather terrible game on its own.
* The ''VideoGame/DukeNukem'' games "Time to Kill" and "Land of the Babes", for the original PlayStation, while decent in their own right, aren't regarded as canon. The fact that they were made by different developers probably has something to do with that. Neither is the N64-exclusive installment ''Zero Hour'', supposedly.
* ''VideoGame/SoldierOfFortune: Payback'' was produced by a low-budget developer, seemingly with a GameMaker program, disregards the characters and story of the previous games.
* When it first came out in 2003, ''VideoGame/TronTwoPointOh'' was supposed to be the official sequel to the movie ''Film/{{Tron}}'', since it seemed almost certain that Disney would never make a second film. Seven years later, when they actually ''did'' release another movie, the continuity differences between ''Film/TronLegacy'' and ''2.0'' proved irreconcilable, so ''2.0'' was rendered non-canon.
* It's a general rule within ''Franchise/{{Pokemon}}'' that the canon game is the third game (Blue[[note]]the Japanese version, split into Red and Blue again for international releases[[/note]], Crystal, Emerald, Platinum, etc). If a previous game is referenced to it's always the third game, which is a mixture of the original two with changes.
* ''VideoGame/GrandTheftAutoAdvance'' is notable in the ''VideoGame/GrandTheftAuto'' series for this. Effectively the only game in the series to receive virtually no input from primary ''[=GTA=]'' developer Rockstar North, it features unique characters (i.e. Mike, Cisco, Jonnie and Yuka) and plot developments (bubonic plague occurring in Liberty City and 8-Ball's arrest that resulted from a Colombian Cartel attack) that are never acknowledged in succeeding [=GTA=] games.
* If you search for the ''Virus Invasion'' series, you'll find ''Virus Invasion 1'' through ''7''; however, there actually existed an eighth game which was removed from the timeline. As it was subjected to an OrwellianRetcon, it is somewhat of a MissingEpisode these days. It has a story behind it which sounds like it was taken from a {{creepypasta}}. Firstly, it was an OddlyNamedSequel called ''Little Bear's Adventure''. It took place at approximately the same point in the timeline as ''Virus Invasion 2'', but was actually made first, shortly after ''VI 1'', and used the same (rather glitchy) engine. It was DarkerAndEdgier too: ever noticed how you play as yellow little bear in ''VI 1'' but cyan little bear in ''VI 2''? Well, that's because the first little bear never actually escaped: he was abandoned somewhere when the others left, becoming the protagonist of Little Bear's Adventure. He tries to escape again, [[FailureIsTheOnlyOption but fails, ''dying at the end'']].
* The universally-loathed {{novelization}} of the ''VideoGame/BaldursGate'' series, in which the protagonist was a {{Jerkass}} KarmaHoudini, was eventually declared non-canon by Creator/WizardsOfTheCoast. Officially, D&D video games are all non-canon to the broader tabletop D&D continuity, letting the video game designers shake up the world however they like without worrying about treading on tabletop designers' and players' toes. However, most ''novels'' are treated as canonical to the tabletop settings unless stated otherwise (a situation classic ''TabletopGame/DarkSun'' players were familiar with and bemoaned), which is why the ''Baldur's Gate'' novel specifically needed excising.
** The Bhaalspawn saga (as in, there were Bhaalspawn and they all killed each other in a way similar to that explored in the games) was made canon in 5th edition, noticeably in a way that excised everything from the novels except the broadest of BroadStrokes in that the Bhaalspawn had the novel protagonist's name and class. [[TakeThat Said Bhaalspawn was then unceremoniously killed in the opening shots of 5th edition]].
* ''[[VideoGame/{{WWE}} WWE '13]]'', features a story mode that allows you to play through the company's Wrestling/AttitudeEra as many of its top stars at the time. The first part lets you play as Wrestling/DGenerationX which, as fans who were watching back then remember, started out as the trio of Wrestling/ShawnMichaels, Wrestling/TripleH, and {{Wrestling/Chyna}}. In the game's retelling of the story, it's just Shawn and Trips. Apparently WWE either wants to forget that Chyna ever worked for them, they want everybody else to, or both.
* The now-closed ''VideoGame/DragonBallOnline'' ignored ''Anime/DragonBallGT'' and even certain elements (read: {{Filler}}) in the rest of the ''Manga/DragonBall'' anime. This was due to Netmarble only obtaining the license for the manga, as well as the Toei character Bardock.
* ''VideoGame/KidIcarusUprising'' is treated as the only sequel to the original ''VideoGame/KidIcarus'', completely ignoring the UsefulNotes/GameBoy sequel ''Of Myths And Monsters'', possibly due to the fact that the sequel was initially only released in America (with a much, much later Japanese release on the Virtual Console), even though it was made in Japan by Nintendo.
* The ''Romeo and Juliet'' quest in ''VideoGame/RuneScape'', which, as of a September 2010 update, has the dubious honor of being the first (and, so far, only) quest to be ''completely'' removed (down to most of the characters) from the game and site features -- including a Postbag from the Hedge letter that, by that time, was nearly four years old. The explanation Jagex gave for removing the quest is that it they felt it simply didn't mesh well with the world of Gielinor. Two other former quests (''Sheep Shearer'' and ''Witch's Potion'') simply got demoted to miniquest status, and several other quests were updated or retooled as time went on.
* ''Parasol Stars'', the second sequel to ''VideoGame/BubbleBobble'', has never had a rerelease (not even in a {{compilation|Rerelease}}) and all the spin-off games ignore it.
* ''VideoGame/SuperAdventureRockman'' was officially disowned by Creator/{{Capcom}} and Keiji Inafune for its overly dark tone.
* ''VideoGame/RatchetAndClankSizeMatters'' and ''VideoGame/SecretAgentClank'' had their canon status disrupted for years because of the ''Future Trilogy''. ''[[VideoGame/RatchetAndClankIntoTheNexus Into the Nexus]]'' officially renders the two games non-canon.
* The second episode of [[DownloadableContent Burial at Sea]] for ''Videogame/BioShockInfinite'' completely nullifies the story of ''VideoGame/BioShock2'' by [[spoiler:making it impossible for certain elements of the game – like the Alpha Series Big Daddies and the link they have with the Little Sisters – to exist within the timeline]].
* Because they couldn't secure the rights with the estate of Creator/EdgarRiceBurroughs after the first game, the events of [[Disney/{{Tarzan}} Deep Jungle]] never happened in the ''Franchise/KingdomHearts'' series.
* The official sequel to ''VideoGame/{{Homeworld}}'' completely ignores the stand-alone ExpansionPack ''Homeworld: Cataclysm''. The only possible hint is the suspiciously low numbers of the [[ProudMerchantRace Bentusi]] left in the galaxy. While many assume it's because the Vaygr killed the rest, it's difficult to ignore that the plot of ''Cataclym'' has the majority of the Bentusi fleeing to another galaxy to escape the [[TheVirus Beast]].

[[folder:Web Comics]]
* {{Lampshade|Hanging}}d in ''Webcomic/{{Narbonic}}'' [[http://www.webcomicsnation.com/shaenongarrity/narbonic/series.php?view=archive&chapter=10108 here]] and [[http://www.webcomicsnation.com/shaenongarrity/narbonic/series.php?view=archive&chapter=10239 here]], where the "two foremost experts in comic-book continuity" explain away all plot discrepancies.
* In ''Webcomic/{{Erfworld}}'', the [[{{Whatevermancy}} magic school]] of [[TakeThat Deletionism]] was replaced by "{{Retconjuration}}" in order to explain how a change was retroactively made to a character's special ability. Therefore, Deletionism has never existed.
* In an early episode of ''Webcomic/TheOrderOfTheStick'', Roy's ghostly father mentions that Xykon killed his master Fyron and his master's son. When these events are depicted in ''Start of Darkness'', no mention of the son is made.
* ''Webcomic/EightBitTheater'': Thief's ninja costume was ''almost never'' red. In context, the outfit was red for the greater majority of one strip. Black Mage lampshaded the color change the following strip while he was descending into his standard state of being pissed off.
-->'''Black Mage:''' (''to Red Mage'') '''You''' suck. (''to Fighter'') '''You''' suck. (''to Thief'') And '''you''' were wearing red a second ago!\\
'''Thief:''' No I wasn't. Besides, what kind of ninja wears bright red?\\
'''Black Mage:''' Ha! I never said it was bright red!\\
'''Thief:''' Neither did I.\\
'''Black Mage:''' Ghk!
* ''Webcomic/ALoonaticsTale'' "Job Hunting" never happened; what we see is a version which was severely neutered to make it acceptable for use in a school assignment. The artist redrew it as "Rehired", the canon version of the story. Rick and Becky use it as a barometer for what does and doesn't constitute valid criticism; anyone who says they thought the original "Job Hunting" was good, isn't going to be any good to them if they need an editor.
* The Second Eaton arc in ''Webcomic/{{Shortpacked}}'' never happened. You just imagined it. [[LetUsNeverSpeakOfThisAgain Now let's never speak about your crazy, drug-fueled hallucination again.]]
* There's an ''in-universe'' example in ''Webcomic/OurLittleAdventure'' with The Lady of Fate and Fortune. The creation of the Magicant caused so much turmoil and greed that the other gods decided to revoke the Fortune Lady's god status and banish her.

[[folder:Web Original]]
* [[WordOfGod Serris]] says that the rebooted ''Furtopia RP'' is not part of the ''Roleplay/DarwinsSoldiers'' canon and never will be.
* In perhaps the only example of this happening ''in-universe'', the characters of ''Fanfic/{{PRIMARCHS}}'' delete 80 chapters of their own story in order to defeat the Plot Hole.
* A weird example is LetsPlay/{{Raocow}}, who in many of his old videos would always say "That was a demo" whenever he made a mistake and immediately fix it using rewinds or savestates. He has since stopped using savestates as much, to the point that he sometimes {{subvert|edTrope}}s it by saying "That totally happened" when he screws up.
* Weirdly subverted in ''WebVideo/TheChurchOfBlow'', where the protagonist of the second series is an actor trying to make a viral Website/YouTube video. Then he starred in the RealLife viral video "Youtube is my Life", which the character is certain does not exist.
* Every LetsPlay by LetsPlay/TheStrawhatNO from before ''VideoGame/BombermanHero'' has been removed from their Website/YouTube channel or set to private/unlisted. Solidified when [=ThornBrain=] updated all of the LP playlists, and ''Bomberman Hero'' is listed as LP #1.
* Sometimes occurs, oddly enough, in ''Roleplay/SurvivalOfTheFittest''. Sometimes a mod or handler declares a scene (mostly in [[DevelopingDoomedCharacters pre-game]] or a character's backstory) as non-canon, for whatever reason. Two examples of scenes declared non-canon by a mod include a thread in v1 where a rejected character actually showed up on the island and randomly killed someone, and a scene in v4 pre-game where a character was prostituting herself out for drugs, with the other character having an implausible amount of drugs on him.
* A small group of administrators at Wiki/{{Wikipedia}} have "[[http://en.wikipedia.org/wiki/Wikipedia:OS oversight]]" abilities, allowing them to restrict the contents of a past edit so that only other administrators, or other oversighters, can see what was removed (usually for libel or privacy reasons). In extreme cases, oversighters can remove the edit from the history, so that only they can tell it was even made in the first place.
* The first two installments of ''Literature/ChaosFighters'', ''Route of Land'' and ''Route of Sea'' are no longer canon and set for rewrite.
* The author of ''Literature/{{Worm}}'' pulled a chapter that he was dissatisfied with a few hours after posting it because it didn't make sense within the context of the story.

[[folder:Western Animation]]
* According to WordOfGod the ''WesternAnimation/{{Ben 10}}'' episodes set in the future are not canon, as they portray Kevin as an unrepentant villain, but in ''[[WesternAnimation/Ben10AlienForce Alien Force]]'', he is a [[HeelFaceTurn redeemed good guy]]. Also, the pop-up edition of the episode "Goodbye And Good Riddance" states that the episode is not canon and that the real story of Ben's return to Bellwood is the live action film ''[[Film/Ben10RaceAgainstTime Race Against Time]]''. However, the ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]'' episode "Ben 10,000 Returns" made all canon inconsistent events alternate universe, including ''Race Against Time'' and the villain Kevin future.
* The ''TabletopGame/HeavyGear'' animated series is considered by WordOfGod to be an [[ShowWithinAShow entertainment broadcast similar to professional wrestling]] within the ''Heavy Gear'' universe, and thus not representative of how things work in the "real" ''Heavy Gear'' universe.
* With ''TabletopGame/BattleTech'', the '90s animated series is said to be an animated shiw within the game's universe. While events similar to it did happen, they did not occur anywhere near like they did in the cartoon.
* It seems everything Disney made before ''WesternAnimation/SteamboatWillie'' is considered discontinuity as Pete, Mickey, and Minnie Mouse are all labeled as having debuted in it. Pete actually first appeared three years earlier in an ''Alice Comedy'' cartoon called ''Alice Solves the Puzzle'', while the other two mice debuted earlier in 1928 in ''Plane Crazy''. Of course considering that their first cartoon featured AttemptedRape [[CharacterizationMarchesOn by the world’s biggest and most kid-friendly icon]], it makes sense Disney does not talk about it.
* GarfieldAndFriends [[https://www.youtube.com/watch?v=Fa0jvoAefp8 third opening theme]] was left out of the final season when it was released on DVD. This especially makes sense considering how much the song was disliked by fans.
* ''WesternAnimation/TheSimpsons'':
** Every [[BizarroEpisode Halloween episode]] is [[RuleOfFunny out of continuity]]. To the extent that the show ''[[NegativeContinuity has]]'' continuity.
** The much-reviled episode "[[Recap/TheSimpsonsS9E2ThePrincipalAndThePauper The Principal and The Pauper]]", where it's revealed that Principal Skinner is in fact a [[FormerTeenRebel former street punk]] pulling a DeadPersonImpersonation of the real Seymour Skinner (who wasn't actually dead), has been marked as non-canon by the writers. Principal Skinner is definitely the genuine article, except on the ''very'' few occasions when the episode's referred to for the sake of a usually [[SelfDeprecation self-deprecating]] joke. {{Lampshade|Hanging}}d in "[[Recap/TheSimpsonsS11E22BehindTheLaughter Behind the Laughter]]" where it presents "The Principal and the Pauper" being written during a period where the Simpsons had a massive falling-out and couldn't stand to be around each other. As a result, the show was forced to resort to [[TakeThat "increasingly nonsensical plots and storylines"]]; cue Principal Skinner announcing he's an impostor.
** The negatively-received "That 90's Show", which attempted to retcon Marge and Homer meeting and getting married in the 90's instead of the 70's and early 80's, has been completely ignored with later episodes revisiting their past once again using the timeline introduced in "The Way We Was".
* In ''Franchise/TransformersGeneration1'', the BigBad Unicron was revealed in season three to have been a GoneHorriblyRight experiment by an alien MadScientist named "Primacron" - his intent was that Unicron would devour all life in the universe, and then Primacron could repopulate the universe with lifeforms of his own creation and design. All subsequent itinerations of ''Franchise/{{Transformers}}'' have stuck with the idea of Unicron as a {{Satan}}ic EldritchAbomination, a concept from the Marvel Transformers comics.
* ''WesternAnimation/JonnyQuest'': Lance Falk, the head writer of ''WesternAnimation/JonnyQuestTheRealAdventures'', instigated an official policy to ignore the events of the 1984 series and the two made-for-TV movies on the show.
* One episode of ''WesternAnimation/FamilyGuy'' involved Lois working as a reporter for Fox news and discovering that Michael Moore and Rush Limbaugh (along with a number of other celebrities) are actually just fictional personas created by Fred Savage. A later episode features Rush Limbaugh having a book signing in Quahog, leading to this conversation:
--> '''Chris''': But I thought Rush Limbaugh was just a fictional character played by Fred Savage...
--> '''Lois''': Where'd you hear that?
--> '''Chris''': Fox News.
--> '''Lois''': Then it's a lie. Everything Fox News says is a lie.
--> '''Chris''': This one's true mom! You saw it with your own eyes and then you reported it on Fox News!
--> '''Lois''': [[MindScrew Even true things once said on Fox News become lies.]]
* Arlene Klasky has said in an interview that she would take delight, along with Gabor Csupo to make new ''WesternAnimation/{{Rugrats}}'' episodes. Of course, this would mean ignoring the events of ''WesternAnimation/AllGrownUp''. Rumor has it that Klasky/Csupo were sick and tired of the spin-off anyway (keep in mind, the spin off only existed due to [[ExecutiveMeddling executive demands]]).
* ''WesternAnimation/StarTrekTheAnimatedSeries'' was largely deemed non-canon by Paramount for decades, even though writers referenced events from the show and managed to force select elements (most notably the episode "Yesteryear", which told of Spock's childhood and was widely regarded as the cartoon's best episode) into canon if only because of their popularity with fans. While the ExpandedUniverse novels got away with referencing the cartoons, in 1989 Paramount put into its contract with DC Comics that writers could not use or reference the cartoon, much to writer Peter David's horror. Ultimately, to promote the cartoons getting a DVD release, CBS, the new owners of the property, did a fan poll to decide once and for all the canon status of the cartoon, with fans voting overwhelming to make the company finally acknowledge it as part of the show's official continuity.
* The ''WesternAnimation/StargateInfinity'' cartoon is officially not part of the canonical ''Franchise/StargateVerse''.
* WordOfGod is that ''WesternAnimation/AvengersAssemble'' is meant to be a sequel to ''WesternAnimation/AvengersEarthsMightiestHeroes'', with a {{flashback}} in one episode showing the Avengers in their costumes and [[ArtShift art style]] from ''EMH''. However, this contradicts some elements seen onscreen (namely that Comicbook/TheFalcon makes his debut as a hero in ''Assemble'', while he was already active in ''EMH''), meaning that the three episodes of ''EMH'' Falcon appeared in are either Canon Discontinuity, or [[BroadStrokes happened differently]]. And in one episode of Avengers Assemble, the characters make a reference to a team of high schoolers that Nick Fury is currently training (''WesternAnimation/UltimateSpiderMan''), however two members of the USM team, Iron Fist and Luke Cage, are clearly shown as adults and members of Heroes for Hire in ''EMH''.
* ''WesternAnimation/TheFairlyOddParents'': ''Film/AFairlyOddMovieGrowUpTimmyTurner'' completely ignores the ending of ''WesternAnimation/ChannelChasers'' as (among other things) Timmy is [[HeldBackInSchool still in fifth grade]] and still has Cosmo and Wanda as fairy godparents. Come ''Film/AFairlyOddSummer'', where [[spoiler: Timmy performed a HeroicSacrifice and AscendedToAHigherPlaneOfExistence]], and the ending to Channel Chasers is an impossibility.
