** After TheFilmOfTheBook made "I shouldn't 'ave said that!" into Hagrid's CatchPhrase, it became one in the books as well.

* In the original version of ''Fanfic/StarCrossedCrusaders'' (which also adapated ''[[VideoGame/JoJosBizarreAdventureThe7thStandUser JoJo's Bizarre Adventure: The 7th Stand User]]''), the climax reveals that [[spoiler:Jotaro's future is the same until where ''Manga/StoneOcean'' should have taken place, much to Vins' confusion. This is followed by how The Path to Heaven is missing from Dio's diary, ultimately revealing it's because of Made In Heaven's collapse, and Pucci no longer exists]]. This is one interpretation of ''Stone Ocean's'' [[spoiler:ResetButtonEnding, since what happened to the rest of the cast was left unclear in the manga]]. The anime would then [[spoiler:[[AdaptationExpansion provide some clarity]] that adds up with this interpretation in its final credits sequence]], which the fanfic predates by 5 years.

** ''Film/StarTrek2009'' canonizes Uhura's first name of Nyota; it was assigned by either William Rotsler or Creator/VondaNMcIntire, depending on who you ask, and endorsed by Creator/NichelleNichols and Creator/GeneRoddenberry, to the point where it was in general use for decades but simply had never managed to make it into a canon production. The same movie canonized the names George and Winona for James T. Kirk's parents, coined in a novel by [=McIntyre=].

** ''Film/StarTrek2009'' canonizes Uhura's first name of Nyota, which was invented by fan William Rotsler and endorsed by Nichelle Nichols, and had been generally adopted for years. The same movie canonized the names George and Winona for James T. Kirk's parents, coined in a novel by Creator/VondaNMcIntyre.
** ''Film/{{Star Trek VI|The Undiscovered Country}}'' finally made official Sulu's personal name of Hikaru, which was the most popular one used since Vonda [=McIntyre=] gave it to him in another novel a decade earlier.

** On the subject of the Death Star, many fans have wondered why the Emperor didn’t instead build a massive fleet of Star Destroyers with the resources it took to create one Death Star. Years later, ''Film/TheRiseOfSkywalker'' has Palpatine [[BackFromTheDead return from the grave]] and do exactly that, with an added bonus of each ship being equipped with a [[EarthShatteringKaboom Planet-destroying laser of their own]].
** ''Film/{{Solo}}'' officially canonizes a popular fan theory about Han Solo's famous Kessel Run. For years, seemingly every ''Franchise/StarWars'' fan had their own favorite explanation for why Han bragged about making the Kessel Run "in less than twelve parsecs" in ''Film/ANewHope'', since a parsec is a unit of ''distance'' rather than time. Some believed that it was an intentional error, meant to demonstrate that [[SmallNameBigEgo Han was just talking out of his ass]]; others believed that he was surreptitiously testing Luke and Obi-Wan's knowledge of space travel, and wanted to see if they would correct him; others believed that he was bragging about the ''Millennium Falcon'''s navigational capabilities, referring to the specific ''route'' that he took through the Kessel system that only a fast ship would be able to make safely.[[note]]This explanation was previously made ExpandedUniverse-canonical in ''Literature/TheHanSoloTrilogy''[[/note]] The last explanation was incorporated into the film as a major plot point: Han once took a particularly dangerous shortcut through the Maw Cluster while smuggling valuable cargo from Kessel, allowing him to complete the run in a much shorter distance than normal. It ''also'' incorporates the "talking out of his ass" theory by Han insisting to skeptical onlookers that it's twelve parsecs "if you round down".

* Minor case but in ''Film/TeenageMutantNinjaTurtles2014'', the Turtles and their outfits look very similar to popular aspects of the “realistic fan art" in the fandom look, especially Raphael's clothing.

** When one of the writers was answering fans' questions in a forum topic on the movie's website, he was asked how Bumblebee was suddenly able to speak at the end of the movie. His answer was that the healing laser Ratchet used earlier in the movie had repaired Bumblebee's vocal processor. When another fan suggested that Bumblebee was healed by the [[MacGuffin AllSpark]], which was clearly shown to heal another damaged Transformer earlier in the movie, the writer admitted that that explanation did make more sense than his answer.

** The grouping of [[AnythingThatMoves France]], [[NoYay Spain]] and [[ChivalrousPervert Prussia]], called the Bad Touch/Friends Trio, started as fanon based on their appearance together in The War of Austrian Succession. It eventually ended up approved by the author, with them appearing in sketches together, in an omake of Prussia's cleaning game and even getting an ImageSong together.

** "L is for Love" confirms the long-held fan theory of Luna being LGBTQ, namely Bisexual.
** Chandler [=McCann=] being Lincoln's personal bully was something that was mostly restricted to earlier fics. The character first appeared in "The Waiting Game", and for a long time that was his only mayor episode. While the episode depicted him as just a generic jerk and freeloader, lots of fanfic writers subjected him to the RonTheDeathEater treatment and turned him into a full blown bully who has it out for Lincoln personally. This combined with a failed attempt to redeem the character in Season 3's "Jeers for Fears" led to the writers following suit and actually making Chandler a bully to Lincoln, starting with Season 5's "Schooled".

** In ''Film/{{Transformers|2007}}'', a very common fan theory was that [[spoiler:[[TheStarscream Starscream]] was among the F-22s that fire on Megatron in the climax]]. The producers haven't said definitely that it's canonical, but their stance so far has been "Sure, why not?" The tie-in comic ''The Reign of Starscream'' acknowledged this by having Starscream consider it, but decide not to. In [[Film/TransformersRevengeOfTheFallen the sequel]], after Megatron is revived with the help of Scalpel, he accuses Starscream of this while beating him with his own severed arm. Starscream responds in a way that leaves it uncertain.

** In the ''Film/{{Transformers|2007}}'' movie tie-in comic, a reader emailed in-character as their neutral fan-character and flirted with Barricade, asking to play "Bad cop bad-cop-pretending-to-be-good-cop." He flirted back. It is now pretty much canonical that Barricade likes chicks.

** A lot of fanfics center on the idea that Bumblebee was raised by the Autobots with Optimus himself usually being his central parental figure. In ''[[Film/TransformersAgeOfExtinction Age of Extinction]]'', Optimus confirms he raised Bumblebee when discussing moody teens with Cade.

** In the ''Transformers'' movie comic, a reader emailed in-character as their neutral fan-character and flirted with Barricade, asking to play "Bad cop bad-cop-pretending-to-be-good-cop." He flirted back. It is now pretty much canonical that Barricade likes chicks.

** [[WesternAnimation/TransformersPrime Breakdown and Knock Out]] were shipped together a whole bunch after their debut. They never managed to get together in the show but appeared as a couple in ''ComicBook/TheTransformersWindblade''.
** Another Transformers: Prime example, "Steve/[=ST3V3=] The Vehicon" was a nickname given to particularly unlucky vehicons across the course of the show. In the comics for ''WesternAnimation/TransformersRobotsInDisguise2015'', a vehicon by this name makes an appearance, it being explained he suffered cranial damage which made him forget his numerical assignment and he found the name "Steve" on a bilboard. It had a pleasing tone.

* ''TabletopGame/BattleTech'' canonized the fan-character [[https://www.sarna.net/wiki/Randolph_P._Checkers Randolph P. Checkers]], the beloved "mercenary professor" persona of BigNameFan Tex of the [[https://www.youtube.com/c/BlackPantsLegion Black Pants Legion]], most known for his highly popular [[https://www.youtube.com/playlist?list=PLR5zhFCFVb9Unr7My0Epa_QQQqa388AVh series]] of ''Tex Talks Battletech'' lore videos. He is officially recognized as an in-universe character in the ''Franchise/BattleTechExpandedUniverse'' novel ''Children of Keresnky'' via a prologue delivered by Dr. Checkers himself.

* In the original version of ''Fanfic/StarCrossedCrusaders'' (which also adapated ''[[VideoGame/JoJosBizarreAdventureThe7thStandUser JoJo's Bizarre Adventure: The 7th Stand User]]''), the climax reveals that [[spoiler:Jotaro's future is the same until where ''Manga/StoneOcean'' should have taken place, much to Vins' confusion. This is followed by how The Path to Heaven is missing from Dio's diary, ultimately revealing it's because of Made In Heaven's collapse, and Pucci no longer exists]]. This is one interpretation of ''Stone Ocean's'' [[spoiler:ResetButtonEnding, since what happened to the rest of the cast was left unclear in the manga]]. The anime would then [[spoiler:[[AdaptationExpansion provide some clarity]] that adds up with this interpretation in its credits sequence]], which the fanfic predates by 5 years.

When this happens between fictional characters, it's a SureLetsGoWithThat. If a particular work has a long and continuous run, fanon may be promoted to canonicity because a PromotedFanboy is now [[RunningTheAsylum calling all the shots]]. A SubTrope is AscendedFanNickname, where {{Fan Nickname}}s are given official use. See also AscendedHouseRules for when a house rules becomes an official rule.

** Countless fanfiction stories from the 2010s (''Fanfic/TheEndOfTheWorld'', ''Fanfic/TheVictorsProject'', ''Fanfic/JohannaMasonTheyWillNeverSeeMeCry'', ''Fanfic/WeMustBeKillers'', ''Fanfic/CheatingDeathThoseThatLived'', ''Fanfic/CheckmateAnlaShok'', etc.) imagine that the mentors for the Hunger Games gather together in an official building to watch the Games and mingle with each other, even though it is never said in the original trilogy. This story has the mentors watching the Games together and working out of the same building.

* Music/ElvisCostello's "Less Than Zero" was basically a TakeThat to English politician [[http://en.wikipedia.org/wiki/Oswald_Mosley Oswald Mosley]], but American listeners who'd never heard of Mosley tended to think the "Mr. Oswald" referred to in the lyrics was UsefulNotes/JohnFKennedy's assassin Lee Harvey Oswald. So when Elvis Costello first toured the US, he started playing a version with substantially rewritten verses that ''were'' in fact about Kennedy's assassination.

** In "Come Together", the line "Hold you in his armchair you can feel his disease" was originally supposed to be "Hold you in his arms yeah" but it was so commonly [[Mondegreen misheard]] that the [[GreatestHitsAlbum Blue Album]] had the former on its inner sleeve, and Music/JohnLennon liked the former lyric more and so all of the covers of the song have the words "his armchair".

* In a host segment of the ''Film/JungleGoddess'' ''Series/MysteryScienceTheater3000'' episode, Joel introduces the bots as Jackie Gleason did with his fellow cast members at the end of every episode of ''Series/TheHoneymooners'', prompting him to introduce Crow as "Art Crow!" (a reference to Art Carney). A child fan of the show missed the reference and sent Best Brains a drawing of the cast labelling Crow as "Art" under the impression that that was his actual name. The letter was shown on the show and ever since Crow was occasionally called "Art" (usually by Pearl Forrester) as a RunningGag.

* From ''Manga/DeathNote'', L's knowledge of capoeira. Originally, that was simply put in because the writer was thinking of ways that one could fight while handcuffed to their opponent. But then some fans pointed out that it looked like capoeira, and eventually in ''LightNovel/AnotherNote'', it became canonical that L has some knowledge of that particular martial art. Note, though, that the canonical status of ''Another Note'' is hotly debated. It's mentioned in the manga reference ''How To Read'', but isn't by the original mangaka, and several things in it appear to either be outrageously untrue (such as the third World War having happened in a world mostly similar to our own) or otherwise clearly inconsistent with the anime and manga canons.

* In [[VideoGame/SwordArtOnline the video game continuity]] of ''LightNovel/SwordArtOnline'', specifically in ''Sword Art Online: Fatal Bullet'', this happens. See, one common nickname for a gender-bent Kirito in fanfics (or sometimes used to refer to his [[DudeLooksLikeALady very feminine]] GGO avatar) is Kiriko. In ''Fatal Bullet''[='s=] Kirito Mode, in order to try to blend in, Kirito uses an alternate account when entering the [=BoB=] tournament (which has the appearance of his canonical GGO avatar). Said account's name? You guessed it: "Kiriko".

** In "Come Together", the line "Hold you in his armchair you can feel his disease" was originally supposed to be "Hold you in his arms yeah" but it was so commonly misheard that the [[GreatestHitsAlbum Blue Album]] had the former on its inner sleeve, and Music/JohnLennon liked the former lyric more and so all of the covers of the song have the words "his armchair".

* Music/{{Devo}}'s "Whip It" was originally meant to be an inspirational song addressed to President UsefulNotes/JimmyCarter. Naturally, though, people thought it was an ObligatoryBondageSong [[ThisIndexTouchesItself or about masturbation.]] This amused them, and they kind of enforced the first interpretation with the music video.

Contrast {{Jossed}} (when fan theories are explicitly debunked by WordOfGod or canonical events), BeamMeUpScotty (when a phrase that's well-known was never uttered in the canon). Inverse of ShrugOfGod (when the creator(s) refuses to give a concrete answer) and OutdatedByCanon (where a later element or explanation in canon outright contradicts the popular fanon of the time).

* ''Website/GaiaOnline'' introduced a pair of RichBitch twins named the Von Helson Sisters to serve as rivals for the resident Megalomaniac during a storyline in 2005. Fans speculated that since the name "Von Helson" sounded a lot like "Van Helsing", coupled with the fact that the twins had an apparently dead father named ''Vladmir'', about half the website jumped to the conclusion that they were actually Vampires. In 2007, Gaia rolled with this and used it both as an opportunity to fill in numerous {{plot hole}}s, and a chance to play off the [[EstrogenBrigade predominately female]] fanbase's ''Literature/{{Twilight}}'' obsession. (The massive Vampire Stake Fest that followed more than made up for that, though.)

** Heck, even the ''main character's name'' is a bit of Ascended Fanon. One of the joke tombstones in the queue reads "Master Gracey, Laid to Rest--No Mourning Please at His Request." Riders began to assume that this "Master Gracey" was the "master" of the house, and quickly began ascribing him every role, from the RapidAging man in the foyer's painting to the "Ghost Host" to the hanging corpse in the Portrait Room. None of these were the case (in fact, the term "master" was used by the servants of a household to refer to every male ''but'' the owner/patriarch, who was simply called "Sir"; the owner's official title would probably be "Lord"), but as before, Disney eventually canonized the term in both [[Film/TheHauntedMansion the movie]] and a series of comics based on the ride.
