* Given that ''WesternAnimation/Incredibles2'' leads off with fighting and defeating the Underminer and then goes into Helen becoming family breadwinner and Bob adapting to being a HouseHusband, ''[=I2=]'' ignores [[ComicBook/TheIncredibles the comic adaptation]] and the ''[[VideoGame/TheIncrediblesRiseOfTheUnderminer Rise of the Underminer]]'' game in favor of only needing the audience to be familiar with the previous film (and, optionally, its spin-off, ''[[WesternAnimation/PixarShorts Jack-Jack Attack]]'').

* ''ComicBook/TheFurtherAdventuresOfIndianaJones'' was launched immediately following the success of ''Film/RaidersOfTheLostArk''. While most of the stories are standard Indy fare, the writers made the understandable assumption that Marion would be a recurring character and she features prominently in much of the run: taking a job with Marcus as head of PR for the museum and often accompanying Indy on his adventures. This it makes it almost impossible to reconcile the series with later movie continuity.

* ''WesternAnimation/XMenTheAnimatedSeries'': Bishop, like his comic book counterpart, was introduced as a time traveler seeking to root out a traitor among the X-Men who would destroy the team from within and lead to his BadFuture where mutants are persecuted, and all signs pointed to Gambit. The "traitor" turned out to be Mystique disguised as Gambit. She was defeated and life returned to what passes as normal for the X-Men. But in the comics, the storyline lingered for quite some and the traitor was revealed to be none other than Professor Xavier himself as his SuperPoweredEvilSide Onslaught.

* ''VideoGame/StarTrekOnline'' is set in a version of ''Franchise/StarTrek''[='s=] 25th century extrapolated from canon as it stood after the release of ''Film/StarTrek2009'' (plus some material incorporated from the ''Literature/StarTrekNovelverse''). Since its 2010 release, several new ''Trek'' TV series have been made, and while Creator/CrypticStudios does its best to incorporate them into game-canon, ''Series/StarTrekPicard''[='s=] story is mostly ignored because its 2397 date directly conflicts with prior game-canon on multiple levels starting with the 2387 supernova: the game went with ''ComicBook/StarTrekCountdown''[='s=] explanation that the star was a distant one called Hobus, whereas ''Picard'' states it was the Romulan sun itself that blew.

Compare SeriesContinuityError, where two or more installments of the same branch of a franchise unintentionally contradict each other. See also EarlyInstallmentWeirdness and ContinuitySnarl. Often results in CharacterizationMarchesOn when a character from the original work ends up behaving differently in the followup than they are depicted in the spinoffs. Not to be confused with SchrodingersCanon, where there's still a chance that the spin-off in question might be considered canonical. The {{Fanon}} counterpart to this trope is OutdatedByCanon, and for mere fan ''theories'' it's {{Jossed}}. See also HiliariousInHindsight, HarsherInHindsight, and HeartwarmingInHindsight.

* The anime adaptation of ''Manga/SaintSeiya'' introduced several elements that contradicted the Manga. The most noteworthy example would be Hyoga's master. The anime introduced a CanonForeigner called the Crystal Saint as his master, only for the manga to reveal that it was actually Aquarius Camus. The Anime tried to patch this over stating the Camus was the master of Crystal Saint.

* ''Franchise/{{Gundam}}'': Creator/YoshiyukiTomino wrote a novel called ''Gaia Gear'', which operates on the assumption that nothing of relevance happened for nearly 200 years following the events of ''[[Anime/MobileSuitGundamCharsCounterattack Char's Counterattack]]''. Needless to say, several sequels like ''[[Anime/MobileSuitGundamF91 Gundam F91]]'' and ''[[Anime/MobileSuitVictoryGundam V Gundam]]'' were produced (some of them with Tomino's involvement) which contradict this, and while ''Gaia Gear'' hasn't officially stricken from canonicity there's no way it can fit into the timeline anymore.

* The ''Franchise/JurassicPark'' films have ignored the video games and comics, despite being promoted as official continuations of the story.

** The final release of ''VideoGame/BaldursGateIII'' more than twenty years later pretty much directly discards some of the most contentious discontinuities with the novels, namely [[spoiler:Jaheira and Minsc]], and thus indirectly rejects anything else from those books. It is also a long awaited return of the franchise that was much publicized and for which the IP owners invested a lot, a sign that videogames are now considered an important part of the lore, reinforcing the status of the original games as canon sources.

* ''VideoGame/BaldursGate'' did this to the [[Literature/BaldursGate very infamous novel]] that was licensed at the same time and released one year... after. The thing is that the novel only shared a few starting and final details, because it was based on a very early script without much developed yet, and completely invented the rest. Therefore, the game managed to discontinue whatever was written even before the novel was published. Anyway the results of the latter left much to desire and are despised by fans even today. The problem is, since videogames are a minor media in the Forgotten Realms lore while books are major sources, technically it would be the novel that supersedes the game... but then comes ''VideoGame/BaldursGateII'' that totally ignores whatever was plotted in there. Then the same writer releases a novel for it, ignoring again what the game developers did. Thankfully, the fans so reviled and despised those books that years later other official Forgotten Realms material such as ''Legends of Baldur's Gate'' have quietly discarded the novel's narrative and characters in favor of ones closer to their game incarnations, though the name of the novel protagonist (Abdel Adrian) is still considered canon according to Murder in Baldur's Gate and comments from Forgotten Realms creator Ed Greenwood (it is supposed, although never confirmed, that this name has always been an unofficial internal name at Bioware since the days of the early drafts, and the novel only recycled it). The final release of ''VideoGame/BaldursGateIII'' thirty years later pretty much discards some of the most contentious discontinuities with the novels, namely [[spoiler:Jaheira and Minsc]], and thus indirectly rejects anything else. It is also a long awaited return of the franchise and a sign that videogames are now considered an important part of the lore, reinforcing the status of the original games as canon sources.

* In the ''Franchise/OnePiece'' manga, Shanks is TheHerosIdol and a mysterious swordsman whose powers, achievements and intentions are very slowly revealed over the course of the series. It can be jarring to look back at old licensed games portraying his playable or boss forms as just some guy once you know he's an Emperor and one of the strongest men in the series.

* ''Manga/ZatchBell'' licensed games always portrayed Zeno as being able to cast the Baou Zakeruga spell or some variant of it just like his brother Zatch can. Zeon only becomes prominent very late in the series, where it is revealed that his [[CainAndAbel beef with Zatch]] is precisely because the younger twin was the one entrusted with this single-user ability despite Zeno being the ChildSoldier undergoing a TrainingFromHell under the King's orders.

** After the new Frieza destruction backstory was revealed, Toei made a [[Anime/DragonBallZBardockTheFatherOfGoku TV special
]] depicting the last stand of Goku's father Bardock as he realizes Frieza will destroy it, which Toriyama liked enough to give Bardock a cameo in the manga when Goku finally met Frieza. This would be contradicted by ''Dragon Ball Minus'' chapter in ''Manga/JacoTheGalacticPatrolman'', with Toriyama giving these events a different take where Goku is sent away deliberately and Bardock is a softer character. This would be solidified in ''Anime/DragonBallSuperBroly'', which incorporates ''Minus'' as part of the opening backstory scene.

** King Kai's exposition also explained that the Saiyans were cavemen who settled on planet Plant and renamed it after their king Vegeta, with ''[[Anime/DragonBallPlanToEradicateTheSaiyans Plan to Eradicate the Saiyans]]'' and ''Anime/DragonBallGT'' elaborating that they slaughtered the native Tsufuru/[[DubNameChange Tuffle]] people and seized their technology in the process. This would later be overwritten by ''Anime/DragonBallSuper'', establishing that the Saiyans were ''always'' on their homeworld (originally named Sadala) with no Tsufruians, and remained somewhat primitive. The ''Broly'' movie also suggests that King Cold took them into his service three generations before Freeza destroyed the planet, rather than Frieza himself doing this just one generation earlier.

* ''Literature/TheHanSoloTrilogy'': Like much of the Star Wars expanded universe, the 2010s movies ultimately knocked this series out of canon: the end of Bria's arc in ''Rebel Dawn'' was superceded by ''Film/RogueOne'' before the entire series was rendered non-canonical by the release of ''Film/{{Solo}}''.

* ''{{Anime/GirlsundPanzer}}'' has the ''Ribbon Warrior'' manga spinoff which began prior to the release of ''Der Film'' and ''Das Finale''. As a result, the manga has several divergence with the main storyline, especially in regards to how BC Freedom High School was handled.

** ''Film/TheRiseOfSkywalker'' ignores Poe having encountered jumptroopers earlier in ''ComicBook/StarWarsPoeDameron'' and Luke's X-Wing being non-operational in ''[[Film/TheLastJedi The Last Jedi]]'' Visual Dictionary.
