[[WesternAnimation Western cartoons]], like other AnimatedShows, have their share of moments that no one wants to remember.

[[folder:Animated Films]]
* Many fans of Creator/DonBluth films disregard the DTV sequels of his movies (which Bluth had nothing to do with, the interesting subversion of this being three times his movies turned into huge media franchises only after he and his die hard fans left):
** This is especially true of the series of sequels to ''WesternAnimation/TheLandBeforeTime'' because any subtext is now gone and they are now musicals, when the original was not. Depending on the fan, you can:
*** Ignore ALL the sequels. They're all results of turning a beloved movie into a CashCowFranchise anyway.
*** Accept the original and the first sequel ''only''. No heart after that.
*** Accept the movies up to ''IV'' and ignore the rest. In ''The Mysterious Island'', the production team radically altered the environment, meaning that the Mysterious Beyond looked like just about anywhere else in the world.
*** Accept the first four sequels, but disregard the rest, due to a writer switch that was perceived to have made things go downhill after that quality-wise.
*** Accept the movies up to ''VII''. Films ''V''-''VII'' each have their good points, and interesting guest characters, but ''VII'' would be the last film to have non-conspicuous computer graphics.
*** Accept the movies up to ''X''. We see Ducky and Spike's relationship get some interesting attention in ''VIII'', we get a reprise of the best song from ''V'' in ''IX'', and in ''X'' we finally meet Littlefoot's dad. But after this, the movies are more sitcom-like in nature, with multiple gag plots, characters like Cera's dad acting wildly {{out of character}}, and even more explicit morals than people claim the first nine sequels have.
*** Accept the movies up to ''XII''. ''The Wisdom of Friends'' tends to be ignored, [[UpToEleven even by diehard fans of the sequel films]], due to its overly silly nature and astondingly bad (even for the series) morals.
*** Accept ALL the sequels. ''The Land Before Time'' is ''The Land Before Time'', no matter what it is.
*** Accept ALL the sequels ''and'' the TV series.
*** Or any variation of the above.
** Fans of ''WesternAnimation/TheSecretOfNIMH'' disregard its LighterAndSofter musical sequel ''Timmy To The Rescue''. Aside from the change in tone, it doesn't help that the sequel kludges continuity with its predecessor, claiming that Nicodemus was a prophet and that he claimed that a son of Jonathan Brisby would become a hero (Nicodemus wasn't a prophet and he made no such claim). While refusing to even acknowledge it as canon, most fans of the original still lament that there isn't enough BrainBleach in the world to wipe the sequel from their memories.
** The third and fourth ''WesternAnimation/AnAmericanTail'' movies are on the receiving end of this reaction. The latter gets this for "being boring".
* The 2nd and 3rd TheBraveLittleToaster movies get this due to being LighterAndSofter than the dark and subtext filled original film.
* The continuity of Disney's classic characters (Mickey, Donald et al.) depends on who you talk to, given they show up in different time periods and appear in works aimed at different age groups.
** Disney's Direct to Video sequels and spin off cartoons of its movies are often disregarded by fans for reasons including resetting CharacterDevelopment, CharacterDerailment, and are generally found to be inferior to their source materials.
%comment% There is no need to list every individual cheapquel that gets disregarded. Also, if you're going to make an entry denying films from the Disney Animated Canon, don't. That "canon" is nothing more than a list of films, not a series of events that take place in a continuity, so listing that would amount to nothing more than Complaining About Films You Don't Like. Also, the Stitch anime is listed in Anime, as that is its proper medium.%
* Many fans of the first ''WesternAnimation/{{Cars}}'' movie deny the existence of the sequel ''Cars 2'' or the spin-off movie ''WesternAnimation/{{Planes}}'', and some will accept ''Cars 2'', but ignore ''Planes'' and the ''Mater's Tall Tales'' animated shorts, or any combination of the above.
* The ''WesternAnimation/IceAge'' sequels are {{Contested|Sequel}} among fans of the first film, but many who enjoyed the first three films agree on pretending that that the fourth film, ''Ice Age: Continental Drift'' never happened.
* Good luck finding a ''Franchise/{{BIONICLE}}'' fan who pays attention to the {{Retcon}}s about how Matoran and every other living thing in the "Matoran Universe" are supposed to be mindless automatons and how being individuals with personality was just a glitch in their AI. Similarly, paying attention to the retcon inducing universal {{Asexuality}} and NoHuggingNoKissing is a rarity, all the more so since the ''Mata Nui Online Game'' and the ''AdobeFlash'' animations, the early material establishing the Matoran's capability to love, is widely considered some of the fandom's favourite parts of the story.
[[/folder]]

[[folder:Animated TV Series]]
* A number of fans of ''WesternAnimation/PinkyAndTheBrain'' refuse to acknowledge the spin-off ''WesternAnimation/PinkyElmyraAndTheBrain'' (pictured), due to, basically, [[TheScrappy hatred]] of that annoying little brat [[WesternAnimation/TinyToonAdventures Elmyra]].
* ''Franchise/{{Ben 10}}'':
** There are fans that rejected the sequel series ''WesternAnimation/Ben10AlienForce'', a reason being because of retcons to Gwen and Kevin's powers and turning the latter character into a good guy.
** There were fans who inverted this and held the episode "Goodbye and Good Riddance" (where Ben returns to his home town at the end of summer vacation and gets outed as being a superhero) as the show's finale as opposed to "Secrets of The Omnitrix" and "Ben 10 vs. Negative 10", and that's just the original series.
** There are fans who liked both the original series and ''Alien Force'' but don't consider ''WesternAnimated/Ben10UltimateAlien'' as canon.
** Several longtime fans of the first three series of the ''Ben 10'' franchise (the original, ''[[WesternAnimation/Ben10AlienForce Alien Force]]'' and ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]'') don't consider ''[[WesternAnimation/Ben10Omniverse Omniverse]]'' canon due to its [[LighterAndSofter change of style]], redesign, heavy use of comedy and absence of the creators Man of Action.
** There are fans who love ''Omniverse'' who don't take some episodes as canon. Such as "So Long, And Thanks For All the Smoothies"; the episode itself isn't bad, it's just that the ending [[spoiler:has Ben [[ReplacementGoldfish recreate the entire universe after it was destroyed, implying that everyone from the previous series is dead and that everyone is just an identical copy.]]]] Another is the "Showdown" two-parter of the third season, in which there is a Retcon Flashback. [[spoiler:Eleven-year-old Ben is obsessed with a new alien, Feedback. Malware, an evil alien entity, rips the alien out and destroys it. After Ben kills Malware, it cuts back to present day and Ben states that, since then, he can't rescan Feedback's species. This creates a major PlotHole, considering that his original Omnitrix was destroyed at the end of AlienForce, therefore such a problem would not exist with the newer model.]]
* ''WesternAnimation/TheCritic'': Most fans of the TV series were disappointed with the webisodes that followed a few years after the show's cancellation. [[http://www.retrojunk.com/content/article/7731/index/ This fan review]] should provide further explanation.
* According to most ''[[WesternAnimation/TheRenAndStimpyShow Ren & Stimpy]]'' fans, ''Adult Party Cartoon'' '''never happened'''. It's rather despised for turning the BlackComedy and VulgarHumor of the original [[UpToEleven far beyond eleven]] to the point that [[CrossesTheLineTwice it crosses lines that were previously thought to be theoretical]], becoming [[DudeNotFunny completely disturbing]] in the process. You know it's bad when even the Games Animation episodes from the original show (which are often disliked by fans due to making Ren more of a {{jerk|ass}} than he already was) are considered masterpieces when compared to ''Adult Party Cartoon''.
* Anything after the ''WesternAnimation/ChannelChasers'' movie of ''WesternAnimation/TheFairlyOddParents'', which wraps things up with a bittersweet flash forward to Timmy as an adult, or anything after Poof's birth, depending on whom is asked. Most fans won't acknowledge the live-action movies either.
* A large amount of ''VideoGame/MortalKombat'' fans wish you would forget ''WesternAnimation/MortalKombatDefendersOfTheRealm''. Its lack of violence compared to its video game basis has been cited by both 1UP.com and Dorkly as a major role in its failure, having only lasted 13 episodes.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', due to its large, nerdy, and rather {{broken|base}} fanbase, has s few points after which some groups of fans just ignore developments.
** The "purist" or "Originalist" contingent of the fandom like to ignore all episodes produced without any creative input from Creator/LaurenFaust. The cut-off here is one of two places: either after "[[Recap/MyLittlePonyFriendshipIsMagicS2E1TheReturnOfHarmonyPart1 Return]] [[Recap/MyLittlePonyFriendshipIsMagicS2E2TheReturnOfHarmonyPart2 of Harmony]]" (the final episode Lauren directly supervised from start to finish), or after "[[Recap/MyLittlePonyFriendshipIsMagicS2E13HearthsWarmingEve Hearth's-Warming Eve]]" (the final script Lauren personally approved).[[note]][[Recap/MyLittlePonyFriendshipIsMagicS2E11FamilyAppreciationDay "Family Appreciation Day"]] and [[Recap/MyLittlePonyFriendshipIsMagicS2E12BabyCakes "Baby Cakes"]] both aired after HWE, but came earlier in production, meaning Lauren approved the final scripts for those too.[[/note]] Still others accept all of the first two seasons (a few of its episodes grudgingly), but ignore everything from [[Recap/MyLittlePonyFriendshipIsMagicS3E1TheCrystalEmpirePart1 "The Crystal Empire"]] onwards due to it and all future episodes having absolutely no involvement from either Lauren or original head writer Rob Renzetti (he left shortly after Lauren did, to head up [[WesternAnimation/GravityFalls another popular cartoon]]). Even some episodes Lauren ''did'' work on receive this treatment due to being unpopular, like [[Recap/MyLittlePonyFriendshipIsMagicS1E15FeelingPinkieKeen "Feeling Pinkie Keen"]] or [[Recap/MyLittlePonyFriendshipIsMagicS1E21OverABarrel "Over A Barrel"]].
** Other plot developments spurred by ExecutiveMeddling in the series may also be regarded by other fans as discontinuity from that point on.
*** The [[RememberTheNewGuy unexpected introduction]] of [[Recap/MyLittlePonyFriendshipIsMagicS2E25ACanterlotWeddingPart1 Princess Cadence and Shining Armor]] during the Season 2 finale rubbed a contingent of fans the wrong way. Especially because Lauren [[WordOfGod had said]] that she intended for there to be only two Alicorn Princesses. Never mind that Lauren herself created Cadence (though admittedly not as an Alicorn[[labelnote:•]] – Lauren created Cadence as a Unicorn, and the character's [[AllThereInTheManual official backstory]] states that she was originally a Pegasus before getting Ascended[[/labelnote]]).
*** [[Recap/MyLittlePonyFriendshipIsMagicS3E13MagicalMysteryCure "Magical Mystery Cure"]] is easily the most divisive episode amongst the non-Purist contingent, due to it ''shattering'' StatusQuoIsGod by having Twilight Sparkle ascend to become the fourth Alicorn Princess. A significant portion of the fandom prefer to deny it happened.
** Unrelated to the Purism arguments, a large portion of the fandom – especially [[TagalongKid Spike]] fans – utterly reject [[Recap/MyLittlePonyFriendshipIsMagicS3E10SpikeAtYourService "Spike At Your Service"]] due to its total disregard for the little guy's established character traits. Spike is shown [[EpicFail failing… miserably…]] at tasks he has done easily before this episode and since it – such things as [[Recap/MyLittlePonyFriendshipIsMagicS1E10SwarmOfTheCentury cleaning]] and [[Recap/MyLittlePonyFriendshipIsMagicS1E24OwlsWellThatEndsWell baking]]. These fans saw his character discarded for the sake of cheap gags; to say they were angry is an understatement.
** ''[[WesternAnimation/MyLittlePonyEquestriaGirls Equestria Girls]]'' got this from a large chunk of the fanbase for turning the ponies into humanoids and placing them in a HighSchoolAU setting.
*** As a result of this, and misinterpreting showrunner Meghan [=McCarthy's=] statement that the movie would not affect the continuity of Season 4, these fans [[{{understatement}} were unhappy]] when movie-original character Flash Sentry cameoed (in pony form) in [[Recap/MyLittlePonyFriendshipIsMagicS4E11ThreesACrowd "Three's A Crowd"]], doing his job as Cadence's bodyguard. Although they were temporarily quelled by staff insisting his inclusion was an animator's decision rather than Meghan's, a second Flash cameo (in a speaking role this time) during [[Recap/MyLittlePonyFriendshipIsMagicS4E25TwilightsKingdomPart1 "Twilight's Kingdom"]] caused these fans to [[BerserkButton absolutely flip their shit]].
** The episode "Daring Don't", which reveals that [[spoiler:adventurer Daring-Do is a real pony and her books are autobiographical]], caused a huge amount of FridgeLogic. Some would rather forget that episode and swear that [[spoiler:Daring-Do is still a fictional character.]]
** Due to the tendency for G4 MLP merchandise to significantly deviate from the show, fanon discontinuity may also occur between fans of the show and fans of TheMerch. This commonly occurs with toys in particular. On one hand, fans of the show often disregard details and backstories of the toys as they are thought to be written by third parties who seemingly have spotty knowledge of the show, while fans of the toys view the toy line's attempts to be more show accurate as moves to pander to more casual adult fans of the show, among other reasons.
** Although the [[ComicBook/MyLittlePonyFriendshipIsMagicIDW American comics]] are popular, a number of fans loudly declare them to be "non-canon" in relation to the TV series, despite WordOfGod insisting otherwise (though there have been a couple of occasions where the comics ended up contradicting the show, unintentionally or retroactively).
*** Even fans of the comics consider the "Nightmare Rarity" arc (Issues 5-8) to be AU at best due to its {{retcon}}ning of how Nightmare Moon came to be (which was itself {{retcon}}ned by [[Recap/MyLittlePonyFriendshipIsMagicS4E1PrincessTwilightSparklePart1 the Season 4 premier]]). A similar but smaller group of MLP:IDW fans vocally ignore the "Reflections" arc (Issues 17-20) due to their disliking the existence of a ''second'' magic mirror similar to [[WesternAnimation/MyLittlePonyEquestriaGirls the first one]] and ''really'' not liking what they consider Celestia's CharacterDerailment.
*** No one in the ''Friendship Is Magic'' fandom pays any heed to any official comics produced outside the USA, not even the Japanese ones. This is because foreign MLP comics are specifically targeted at children (whereas the IDW comics are "all ages" and actually aim slightly ''older'' than the TV series does). Ire and shunning is especially reserved for the German comics, which are notorious for their poor art and storytelling.
* When nostalgic 80s kids and bronies alike think of or draw Megan from the original ''Franchise/MyLittlePony'' cartoons they tend to ignore her TeamMom interpretation in ''WesternAnimation/MyLittlePonyAndFriends'' in exchange for her WesternAnimation/MyLittlePonyTVSpecials version, most specifically the ''Rescue from Midnight Castle'' one.
* ''WesternAnimation/{{Gargoyles}}'' season three, "The Goliath Chronicles". The writing staff changed completely and had no grasp of series continuity. Most noticeable in the season's second episode, 'Ransom', where [[MamaBear Fox]] is easily restrained by a human thug while her son is kidnapped and later reduced to crying in a chair, clutching his teddy bear, when in the previous seasons, she was established as a deadly ex-mercenary who fought and nearly defeated a nigh-all-powerful Fairy King with previously-unknown magical powers a few hours of giving birth.
** [[WordOfGod Greg Weisman]] himself points this ''very'' thing out when he's criticizing this episode, which make sense considering how much effort the original show made to have strong and likable female characters.
* ''Franchise/GIJoe'' fans often do not count the DIC series as canon because of its inferior writing. And many fans tend to ignore everything that happened [[WesternAnimation/GIJoeTheMovie after Cobra's failed attempt to blow up the Statue of Liberty]].
* ''WesternAnimation/SouthPark'':
** A majority of fans wish that the {{Two-Part Episode}}s "You're Getting Old" and "Ass Burgers" NEVER happened.[[note]] The irony is that the latter was itself a CanonDiscontinuity[=/=]{{Retcon}} of the former.[[/note]]
** Mr. Garrison's sex change gets this treatment, as many thought it wasn't funny, added nothing to his/her character, and was more a WriterOnBoard moment than anything. Even though it eventually got the reset button treatment in "Eek! A Penis", many fans feel the whole "Mrs. Garrison" arc was pointless and shock value only for the sake of such.
** Many fans absolutely hate "Stanley's Cup" due to its AssPull DownerEnding where [[spoiler:Stan's team of hockey players get beaten to a pulp by the Detroit Red Wings]].
** "Ginger Cow" is disregarded by fans due to the massive Kyle-bashing ever and Cartman getting away scot-free.
* For quite a few fans, the ''WesternAnimation/TomAndJerry'' episodes directed by Gene Deitch never happened. Simply put: If it didn't come from Hollywood USA, it's not a ''WesternAnimation/TomAndJerry'' cartoon. The Creator/ChuckJones-produced ''Tom and Jerry'' cartoons from the mid-late-60's zig-zag this a bit; they're nowhere near as beloved as the original Hanna-Barbera ''Tom and Jerry'' shorts, but they're not despised like the Gene Deitch incarnation. Creator/ChuckJones himself said he didn't care much for them.
** Further incarnations also elicit this in different forms.
* Fans of ''WesternAnimation/DextersLaboratory'' usually ignore the 3rd and 4th seasons due to the original creative staff leaving and the show becoming ''remarkably'' different as a result. It helps that the second season finale was intended to wrap up the series. There are some willing to accept the TV movie ''Ego Trip'' as canon, given the original creator's involvement in making it.
* Fans of ''WesternAnimation/ThePowerpuffGirls'' disown everything after "Power-Noia", when Chris Savino took over as producer (creator Creator/CraigMcCracken left to start up ''WesternAnimation/FostersHomeForImaginaryFriends''). The nadir was the episode "West In Pieces", which won a special juried Emmy. The series took a jarring shift in tone, turning from a lighthearted action show into a crude gag comedy where the main characters just so happened to have superpowers.
* ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'':
** The two-parter story "The Once and Future Thing" attracted a lot of flak from both Batman/Wonder Woman shippers and haters of ''WesternAnimation/BatmanBeyond'' when it proved that the series ''WesternAnimation/BatmanBeyond'' was the canonical future of Franchise/TheDCAU, with Bruce going on to end up a lonely, bitter old man.
** The episode "Epilogue" also took flak from many fans of ''WesternAnimation/BatmanBeyond'' when it revealed that [[spoiler:Terry [=McGinnis=] was actually the biological son of Bruce Wayne, courtesy of [[WellIntentionedExtremist well-meant meddling]] from Amanda Waller]]. Many fans rejected this because they disapproved of the idea that [[spoiler:Terry [=McGinnis=] was "genetically destined" to be the next Batman, instead of being an ordinary person who chose to be extraordinary, like Bruce himself]]. Shipping wars were another major reason for the BrokenBase, as "Epilogue" establishes that Terry's relationship with Dana (unpopular with many fans) is stable and long-term, implying they will marry, in stark contrast to fanon that had them breaking up shortly after the series ended.
** Quite a few fans of the DCAU like to think of ''WesternAnimation/BatmanBeyond'' (specifically, ''[[WesternAnimation/BatmanBeyondReturnOfTheJoker Return of the Joker]]'') and its SpinOff ''WesternAnimation/TheZetaProject'' as an alternate future rather than the canon one. This isn't because they don't like it (plenty think it was better than most of the series), but because nobody wants to live with the knowledge that Tim Drake will be [[spoiler:so [[BreakTheCutie brutally tortured]] and {{Mind Rape}}d]] that it takes [[spoiler:him the next ''fifty years'' to fully recover]], essentially making the entire history of the DCAU Bat-family [[spoiler:a case of ShootTheShaggyDog]]. Considering [[TraumaCongaLine what DC is doing to Tim in the comics]]? It almost makes anything SelfDemonstrating/TheJoker does to him look ''tame''. There are also people who just don't want to think of Bruce Wayne as a withered-looking old man or anyone else running around in the Batsuit.
* The offscreen relationship between Bruce and Barbara that occurred between ''WesternAnimation/BatmanTheAnimatedSeries'' and ''WesternAnimation/BatmanBeyond'' is well-hated by fans, due to the UnequalPairing aspect and the implications of a [[{{Squick}} love triangle between a father and adopted son]].
* Some fans of the DCAU do not consider ''WesternAnimation/StaticShock'', ''WebAnimation/GothamGirls'', and ''WesternAnimation/TheZetaProject'' as canon, mainly because of their more "childish" nature, and not being created by Creator/BruceTimm and Creator/PaulDini. Same with the WebAnimation/{{Lobo}} web show, except it is not childish. However, in addition to several DCAU crossover episodes, including a ''WesternAnimation/BatmanBeyond'' crossover, Future!Static also appears in an episode of ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]''. Because of Static being mentioned meeting with Franchise/GreenLantern in a JLU episode, which ''did'' happen in SS, most fans use BroadStrokes.
* ''WesternAnimation/FamilyGuy'' has this in '''spades''':
** Due to a perception amongst the fanbase of declining quality since [[UnCancelled the show's resurrection in 2005]], plenty of former fans prefer to believe the show ended with the third season – specifically either "Family Guy Viewer Mail" (final episode aired during the original run), "Road To Europe" (final episode produced) or "When You Wish Upon A Weinstein" (the BannedEpisode; final pre-cancellation episode to be released). Basically, everything made after David Zuckerman left is ignored. However, exceptions are often made for "Road to the Mulitverse" (the Season 6 premier) and sometimes for "Blue Harvest" (the first ''Film/StarWars'' parody).
** If you want to keep fans happy, do ''not'' acknowledge the episode "Not All Dogs Go To Heaven" in any way.[[labelnote:Text dump here!]] Though most reviews at the time pegged the episode as SoOkayItsAverage (they liked the "Stewie hangs out with the ''Star Trek: The Next Generation''" story, but felt that the "Meg converts to Christianity and Brian stops it so he can drink again" main story wasn't very good), a lot of fans have ranted and raved over the UnfortunateImplications about religion and atheism (even though it does have some good messages about fundamentalism and irrationality in religion being dangerous. The DVD commentary stated that Creator/SethMacFarlane knew the fans [[JustHereForGodzilla were only interested in the episode because of the Star Trek B-story and were pissed that it didn't get enough airtime]] and was trying to make the A-story as even-handed about atheism vs. religion as possible. If anything, it was the Internet fans who blew the whole thing out of proportion, as there were no admissions that the episode was an OldShame, even though there is a running joke about how episodes that focus on Meg are the worst episodes of the show, when really, the writers like the challenge to try and make Meg a more well-rounded character).[[/labelnote]]
*** Quagmire's infamous rant about Brian's personality in "Jerome is the New Black" (a Season 8 episode) was praised by the Internet for being an "apology" to fans for "Not All Dogs Go to Heaven", even though the writers, according to the DVD commentary, didn't intend this (they just wanted to give Quagmire more of a reason to hate Brian, topping it all off with the fact that Brian is just a pretentious bore). Although, see below for how ''that'' turned out.
** Some fans will acknowledge the fifth season simply for the introduction of Brian's then-current girlfriend [[DumbBlonde Jillian]], but completely disregard everything after their breakup in "Movin' Out (Brian's Song)".
** A lot of season 7 episodes – aside from "Road to Germany"[[note]] (the episode where Brian and Stewie use the time machine to go back to 1939 and save Mort Goldman from the Nazis)[[/note]] and "Ocean's 3˝"[[note]] (the episode where Bonnie gives birth to Susie after being pregnant with her for over 6 seasons and Joe tries to pay for her medical expenses by stealing)[[/note]] – are ones that most fans don't want to remember.
** Some fans ignore the Season 10 episode "Screams of Silence: The Story of Brenda Q." Now, ''Family Guy'' has done dramatic episodes before, like "Brian and Stewie", "Dog Gone", some parts of "Jerome is the New Black", and the pre-cancellation episode "Brian Wallows and Peter's Swallows". But an episode playing domestic violence for drama coming from a show that isn't afraid to show women being beaten up, sexually harassed, sexually assaulted, and mocked for their appearance and age, feels cheap and hypocritical.
** The Season 12 episode "Life of Brian" – in which Brian is very graphically run over by a car, is briefly dead for the next two episodes, and is replaced by new dog Vinnie – has ripped the show's already-tattered fanbase ''to shreds''.
** A lot of fans want to pretend that the whole Quagmire/Brian rivalry never happened. Considering the show's near-total abandonment of it, it appears the writers want to as well.
* ''WesternAnimation/TheSimpsons'':
** Special mention should go to "The Principal and the Pauper", the episode where it's revealed that the Principal Skinner we've known throughout the show's long-running history (8 seasons at that point) is actually [[DeadPersonImpersonation a fraud named Armin Tamzarian]]. The episode is an [[CanonDiscontinuity in-show example of discontinuity]], too, because the characters in-show [[StatusQuoIsGod decide they prefer the fake Skinner, run the real one out of town, and a judge orders that they never speak of the incident again]].
** The only episode more reviled for its blatant abuse of canon than "The Principal and the Pauper" is "That '90s Show" which depicts the lives of The Simpsons throughout the 90s, completely ignoring that the events of episodes which aired during the show's earlier seasons that took place in the 90s, and completely rewriting canon as a result. This may have been upgraded to CanonDiscontinuity in later seasons, since they continue to depict Homer and Marge as having gotten together in the late 1970s into the 1980s.
** "The Boys of Bummer" and "Million Dollar Abie" are disowned for showing abuse to Bart and Grampa respectively that goes beyond BlackComedy.
** "Saddlesore Galactica" and "Kill the Alligator and Run" aren't well-liked and are considered the reasons why ''The Simpsons'' hasn't been funny in ages, though "Saddlesore Galactica" is more divided, as some people (and the Simpsons writers) see the episode more as a surreal [[SelfDeprecation piss-take against The Simpsons' own decline in quality due to repetitive storylines and exaggerated characterizations]]. "Kill the Alligator and Run," however, doesn't have that luxury of being re-seen as a ParodyRetcon and is often put on Internet lists for "Worst Simpsons Episode Ever".
** "Bart-Mangled Banner" for being so heavy-handed against Republicans and conservatives that Creator/SethMacFarlane could rewrite it as a ''WesternAnimation/FamilyGuy'' episode by just changing the names and no one would be able to tell the difference.
** Some fans treat "Lisa the Vegetarian" as this, not for being bad (it's considered genuinely funny), but that they feel this episode started Lisa's eventual {{Flanderization}} into a SoapboxSadie (which it was, due to Paul [=McCartney=] only agreeing to do the episode if Lisa stayed vegetarian for the rest of the show's run. The fans saw it as a sign that the Simpsons' writers were kissing the asses of the guest stars they let on the show).
** Fans usually ignore the presence of Sideshow Bob's Italian wife and son as seen in "The Italian Bob". Possibly CanonDiscontinuity as they're never seen or mentioned again after "Funeral for a Fiend".
** "Homer vs. Dignity" is hated by many for sinking to ''WesternAnimation/FamilyGuy''-cum-''WesternAnimation/SouthPark''-esque levels of vulgar humor (though the same can be said for a lot of episodes from Mike Scully's era of being show-runner. The panda rape scene crosses the line into DudeNotFunny territory with sickening abandon; rarely does a two-minute scene turn an otherwise unremarkable episode into one of the most-hated in the show's history and a regular on "Worst Simpsons Episode" lists.
** The Al Jean episodes are hated just as much, only for different reasons – namely, being boring, derivative, full of forced humor, and carrying an air of WereStillRelevantDammit due to dated pop culture jokes. In fact, it's just safe to say that anything after season 8 on ''The Simpsons'' is a mixed bag at best, but has ''some'' good moments in it, though those have been getting rare since season 13.
** Some fans treat "Mother Simpson" as the only time Mona Simpson appears, as they feel her later appearances cancel out its ''very powerful'' TearJerker ending.
* Loyal ''WesternAnimation/JimmyNeutron'' fans have despised ''WesternAnimation/PlanetSheen'' and wish it never happened while wondering why Jimmy Neutron wasn't just given a new season. Poor animation, lack of originality and rampant use of BadBadActing are commonly cited reasons by fans to stay away from the spin off. The fallout was so great that the ratings took a drastic landslide following its premeire, resulting in the series being ''[[FireflyEffect aired out of order]]'' and then moved from Nickelodeon to Nicktoons. Eventually Nickelodeon said "Screw it" and canceled the series without announcement, leaving the series to end on a sad note of [[AbortedArc Sheen never returning to Earth]].
* ''WesternAnimation/SpongebobSquarepants''
** Anything after {{the movie}} and {{uncancell|ed}}ation is usually reviled and often ignored, due to the original producers and writers leaving the series (including creator Stephen Hillenburg), and the series ultimately becoming a FranchiseZombie, especially considering that the movie was originally intended to be the series finale. In fact, ''WE'' have a [[JustForFun/SpongebobSquarepants Just For Fun page]] that pretends the latter seasons didn't exist.
** Some fans will excuse Season 4, the first post-cancellation season, from discontinuity, saying that while it's not as good as seasons 1-3, it's not as bad as anything from season 5 onward.
** It's '''not''' a good idea to mention the words "A Pal for Gary", which depicts [=SpongeBob=] as so ignorant and stupid towards Gary (even by those who tolerated his increased stupidity in later episodes), it's like he's a whole new character entirely.
** Mr. Krabs also had it worse in One Coarse Meal, in which he abuses Plankton's fear of whales to make him quit stealing the formula. Plankton is eventually sent into [[DrivenToSuicide suicidal depression.]] He gets away with it, too,
* ''WesternAnimation/TotalDrama'':
** A good chunk of fans believe that ''[[SophomoreSlump Action]]'' (and to a lesser extent ''World Tour'') never happened.
** ''All-Stars'' got this treatment, which was considered an utter disaster by many. Some even go as far as to say that it was all nothing more than a dream Chris had while in prison after being arrested in the finale of ''Revenge of the Island''.
** ''Pahkitew Island'' also gets this treatment as well and just like with ''All-Stars'', some pretend that it was all a dream.
* ''Franchise/StarTrek'':
** In a reversal of the standard discontinuity reaction, quite a few fans ''did'' consider the [[WesternAnimation/StarTrekTheAnimatedSeries animated series]] {{canon}} when it [[CanonDiscontinuity officially wasn't]] (except for certain details verified later in-canon). It was declared canon after a poll on the official ''Franchise/StarTrek'' website in the late noughties, leading to the trope being played straight with fans declaring Discontinuity on that series as well.
** "Yesteryear" was an almost universal exception, beloved for portrayal of Spock's childhood on Vulcan. The backstory the episode established for Spock is considered to be a completely canonical history, and elements of the episode made it into the 2009 franchise [[Film/StarTrek reboot]].
* ''WesternAnimation/DannyPhantom'':
** Most fans refuse to acknowledge the third ([[ScrewedbytheNetwork and final]]) season of the show, [[SeasonalRot due to head writer Steve Marmel leaving the series]], the new writers [[StatusQuoisGod ignoring past character development]], and the way in which [[LeaveThePlotThreadsHanging plot threads are left hanging]] (despite the creator knowing it would be the last season). Even those who acknowledge the last season often ignore the finale episode ''Phantom Planet'', due to its [[spoiler:revealing Danny's secret to Valerie and his parents, and possibly the world]]. They prefer to play around with the plot ideas that were nullified by this episode.
** Butch Hartman has gone on record that the ghosts are, in fact, not actual ghosts but rather monsters from another dimension. They were born ghosts. Almost all fans ignore this, especially since it contradicts the series itself.
* ''WesternAnimation/AvatarTheLastAirbender'':
%comment% The live action movie cannot be listed here as it is an adaptation. Adaptation Decay is not Discontinuity.%
** The episodes "The Great Divide" and "Avatar Day" receive this. Although the latter gets a pass as it fills in history on one of the previous Avatars.
** The SequelSeries, ''WesternAnimation/TheLegendOfKorra'', is mostly looked on as well-written - if a bit rushed due to being first billed as a quick mini-series, then a single season, then multi-seasons ALL DURING PRE-PRODUCTION - and faithful follow-up to the original series. Many fans take issues with either certain elements (the {{Steampunk}}/GangsterLand setting rather than MedievalStasis being most prevalent), the somewhat rapid establishment and changing of the LoveTriangle between first Mako/Korra/Bolin then Korra/Mako/Asami, or the fact that [[DieForOurShip any given character ended up in a relationship with the "wrong" person or none at all]]. There are, of course, the groups that deny the entire series exists, simply because their [[OneTruePairing preferred couples]] from the first series never became canon.
** There are more than a few fans who disregard the reveal of Amon's true identity, and his [[spoiler: true motivations]], preferring the character as he was before said reveal.
** There are others who are fine with Book One: Air, but feel that Book Two: Spirits and its "Beginnings" episodes came dangerously close to a retcon of both the Avatar world as well as [[spoiler:the reason for the Avatar's existence, having almost nothing to do with the ability to control all four elements and more focused on the fact that a human merged with Raava, the spirit of light]].
** There are fans who liked the "Beginnings" episodes of Book Two: Spirits, but dislike the whole season altogether.
** There are fans who dislike the twist in the third-to-last episode of Book Two in which [[spoiler:Varrick is revealed to be a bad guy]].
* Although liked as an episode, ''WesternAnimation/{{JEM}}'' fanfic writers ignore the episode "The Day The Music Died".
* ''WesternAnimation/KimPossible'' fanfic writers ignore the hook up between Bonnie and Senor Senor Junior. This may have to do with the fact in the episode where said hook-up happens, Bonnie rigged an election to become homecoming queen (instead of Kim) and we also learn Brick Flagg (her ex-boyfriend) broke up with her. So Bonnie gets Junior as a replacement boyfriend, and gets [[KarmaHoudini no punishment]] for rigging the election. That or it's so they can ship her off with someone else.
* ''Franchise/{{Transformers}}'':
** Some fans ignore everything after ''WesternAnimation/TransformersTheMovie'' (the animated one) or Season 2. ''WesternAnimation/BeastWars'' fans often ignore ''WesternAnimation/BeastMachines'' and/or the ''Beast Wars''-specific comic stories, and others ignore ''Beast Wars'' itself. And fans sometimes reject that the comics {{retcon}}ned the origins of Unicron and Primus in ''every'' continuity. Many fans also deny ''The Rebirth'' as canon, mainly because of its poor writing, animation, and characters. Ignoring this is made easier by the fact that the anime series TransformersHeadmasters takes place after Season Three, but ignores ''The Rebirth''. Wiki/TFWikiDotNet has a good article on "[[http://tfwiki.net/wiki/Personal_canon Personal Canon]]".
%comment% Note: Transformers Animated cannot be listed here as it takes place in its own continuity. If you're going to list Kiss Players, that belongs in Anime, and if you're going to list the Michael Bay films, they take place in their own continuity and so cannot be listed anywhere in this index.%
** Many fans of ''Anime/TransformersArmada'' like to ignore ''Anime/TransformersEnergon'' due to its poor animation and storyline as well as the fact that it completely undoes the CharacterDevelopment that [[NobleDemon Star]][[EnsembleDarkhorse scream]] received in ''Armada''.
* The 5th season of ''WesternAnimation/TeenTitans'' gets this for introducing a slew of new characters, spending episodes focusing on them, concluding with a DownerEnding finale, and the fact the series was focused on Beast Boy when he had already had a season long arc in season 2. This is also inverted concerning ''Teen Titans''. There are fans who work it into the DC Comics Animated Universe, not caring for any {{Continuity Snarl}}s.
* ''Franchise/ScoobyDoo'':
** Some Fans like to pretend [[TheScrappy Scrappy Doo]] does not exist. Creator/CartoonNetwork helped foster and expand this in specials like The Scooby Doo Project and during an episode of ''Mystery Inc.'' when Daphne sees a bust of Scrappy, tries to say something, and is reminded by Fred that they promised never to speak of him again. Creator/WarnerBros seems less vocal as a whole. They still sell his episodes each release and in Scooby Doo and the Goblin King, an stand of Scrappy toys are crashed into by a villain driven mystery machine, is it a TakeThat at Scrappy or a TakeThat at people who monstrously attack him?
** Some others have different jumping off points. For some people it's A Pup Named Scooby Doo, Scooby Doo and the Cyber Chase or everything but ignoring the following two:
*** ''WesternAnimation/ShaggyAndScoobyDooGetAClue'', which involves the titular characters behaving as though they were secret agents gets this as well on the grounds that the two characters do not behave as they did in prior ''Scooby-Doo'' incarnations. It probably does not help either that Daphne, Fred, and Velma are merely guest characters as opposed to main ones in that show.
*** ''WesternAnimation/ScoobyDooMysteryIncorporated'' is something of a BaseBreaker. It is deemed the best Scooby ever by some (but a lot of which seem to be the types that didn't much like Scooby in the first place), while others consider it a bad attempt at a reboot for Cartoon Network. CriticalResearchFailure and TheyJustDidntCare are often signalled here as they have always been on people that don't like Cartoon Network's reboots of older properties, [[WesternAnimation/SpaceGhostCoastToCoast even from day one.]]
** With a LongRunner like ''Scooby-Doo'', there is of course the Purist contingent who only acknowledge the classic episodes from 1969 into the late 1970s (up until Scrappy-Doo's introduction).
* There are fans of ''WesternAnimation/{{Rugrats}}'' who think the show fell off when Tommy's brother Dil and/or Chuckie's stepsister Kimi were introduced and won't even acknowledge ''WesternAnimation/AllGrownUp'' as a spin-off of the original show.
* Some fans pretend that season 4 of ''WesternAnimation/ReBoot'' never happened due the characters suffering from {{Flanderization}}, Hexadecimal's [[spoiler:HeroicSacrifice]], and the ResetButton being pressed with [[spoiler: Bob reverting back to his season 1-2 design and Megabyte coming back after having a perfect send-off in season 3]]. And some do count the first half of season 4, but ignore everything [[spoiler:after Megabyte-Bob appears.]]
* There are fanfic writers of ''WesternAnimation/PhineasAndFerb'' who pretend that the ending of ''[[WesternAnimation/PhineasAndFerbTheMovieAcrossThe2ndDimension Across the 2nd Dimension]]'' [[spoiler:where everyone has their mind wiped]] does not happen.
* The 1980s revival of ''WesternAnimation/TheJetsons'' is not acknowledged by the some of the series' fans. For some reason Boomerang stopped airing them in the mid 2000s despite having been well on air all throughout the 90s.
* ''WesternAnimation/CodenameKidsNextDoor'':
** The revelation that Heinrich is [[spoiler:a girl]] is considered untrue by a number of fans, mainly due [[ShockingSwerve to the utter lack of build-up to this twist]] just for the sake of wrapping up Heinrich's plotline before the series ended.
** Also considered non-canon is Chad's [[spoiler:being a double agent all along during his time with the Teen Ninjas]] [[ShockingSwerve for reasons similar to Heinrich's twist]], to the very final episode where [[spoiler:Numbuh 1 ends up having to leave Earth to help the Galactic KND]].
** Some 1x5 (or 5 x anyone else) shippers want to ignore the fact that [[spoiler:Numbuhs 2 and 5 get married in the future]], despite the fact that it had a little bit of foreshadowing.
* At least a few ''WesternAnimation/InspectorGadget'' fans pretend there was never an additional season that [[TheOtherDarrin changed the voice cast]] and introduced [[TheScrappy Corporal Capeman]].
* ''WesternAnimation/{{Futurama}}'':
** Several fans do not count any of the episodes after "The Devil's Hands Are Idle Playthings" as canon and refuse to acknowledge the made-for-DVD movies and the Creator/ComedyCentral episodes as canon. Then are a few who are more willing to accept the films but feel ''Into the Wild Green Yonder'' was the end of the series and none of the episodes after that are canon.
** Some fans refuse to acknowledge that Calculon and Roberto were KilledOffForReal (even though there was an episode where Calculon is brought back to life, only to realize that no one wants him back and he ends up dying again after giving the best acting performance of his life, and Roberto randomly appeared in a minor role in the penultimate episode).
* ''WesternAnimation/{{Daria}}'':
** Most fans hate the episode "Depth Takes a Holiday" so much to the point that fanfics have been written just to explain how it never happened and isn't canon. Granted, despite no AllJustADream disclaimer at any point, the episode was probably never intended to be taken too seriously or intended to be canon.
** The same with "Daria!", the MusicalEpisode. In both cases it largely has to do with the BizarroEpisode themes interfering with the show's general realism.
** It's also best not to talk to any ''Daria'' fans about the episodes where Daria dates Tom after Tom breaks up with Jane. Or the episode where Daria has to choose between contacts and glasses ("Through a Lens Darkly"), due to how out-of-character it makes her.
* Some longtime ''WesternAnimation/XiaolinShowdown'' refuse to consider the sequel series ''WesternAnimation/XiaolinChronicles'' as canon due to network change, more [[DenserAndWackier comedic tones]], changes to the names of many of the Shen Gon Wu magic items, {{retcon}}s, extreme {{flanderization}} of the cast, inclusion of the new character [[TheScrappy Ping-Pong]], lack of the original voice cast and production moving to Canada.
* A very common situation for EasternEuropeanAnimation. A lot of the Soviet shorts series like ''Animation/NuPogodi'' were continued after USSR collapsed. In half the cases, these sequels are universally hated. In the other half, they are just as universally unknown.
* Most fans of both ''{{Futurama}}'' and ''TheSimpsons'' ignore the CrossOver special "Simpsonrama" for various reasons, like implying the Futurama universe is a CrapsackWorld.
