Fans are asked to send in stuff that will be incorporated into the show's {{Canon}} or BonusMaterial (particularly SideStoryBonusArt). It could range from lines of dialogue, to [[FashionDesigner costume]]/monster/vehicle designs, to entire plot points.

A common form is to directly ask fans for stuff, and they send it in. Sometimes there is a contest for a major thing to incorporate. Credit is usually given to the senders, partly as a courtesy to the fans, and partly to avoid UsefulNotes/{{Plagiarism}}.

This may or may not be considered a good thing. If fan-created elements seem to take over the show, it can be seen as the writers going creatively bankrupt (like there is RunningTheAsylum). On the other hand, some elements help the fans feel like they are part of the show, helping old and new fans stay invested.

A SubTrope of AudienceParticipation (this trope require a process to submit and apply, unlike the other forms).

A SisterTrope to AscendedFanon, AscendedFanfic, FandomNod, AscendedMeme (neither one is directly asked for, but they're still incorporated into canon), FourthWallMailSlot (which ''is'' directly asked for, but usually ''isn't'' canon).

Compare CaptionContest, ContestWinnerCameo, HarpoDoesSomethingFunny (having the actors submit stuff that wasn't in the script), ThrowItIn, PromotedFanboy, ApprovalOfGod.
!!Examples Alphabetically By Medium:


[[folder: Anime and Manga ]]
* Okayado has asked fans of ''Manga/DailyLifeWithMonsterGirl'' to submit self-portraits along with what type of {{monster girl}}s they'd like to be paired up with. Which is the source of all the minor human characters that's been popping up in the manga lately.
* ''Manga/FairyTail'' did something like this where fans were allowed to design characters for villains. They showed up as the Hungry Wolf Knights in the ''Grand Magic Games Arc''.
* The first half of episode 67 of ''{{Manga/Gintama}}'' was based on the winning submission for a contest to create an amanto character.
* ''{{Franchise/Gundam}}'' has done this on a few occasions. ''[[Manga/MobileSuitCrossboneGundam Crossbone Gundam]]'' features a mobile armor, the [[http://www.mahq.net/mecha/gundam/crossbone/ema-06.htm Elgolela]], designed by a fan -- Kanetake Ebikawa, who [[RunningTheAsylum went on to design mobile suits for]] ''[[Anime/MobileSuitGundam00 Gundam 00]]''. Likewise, ''[[Anime/MobileSuitGundamSEED Gundam SEED]]'' let fans submit designs for the MSV line; the winner was the [[http://www.mahq.net/mecha/gundam/seed-msv/gat-x105+p204qx.htm Lightning Striker]] MechaExpansionPack for the Strike Gundam.
** Most of the pre-0079 UC timeline was also originally created by fans.
** ''Anime/GundamBuildFighters'' and ''Anime/GundamBuildFightersTry'' have done this, allowing fans to create suits via three ways - coloring a picture of a Mobile Suit via ''Gundam Try Age'', building an actual Gunpla or using the video game ''Gundam Breaker'' and ''Gundam Breaker 2''.
* The creators of ''Manga/{{Kinnikuman}}'' and ''Manga/KinnikumanNisei'' thrive off fan-submissions, with many of the series {{Ensemble Darkhorse}}s coming from fan characters that caught on, such as Ramenman.
** The creator of ''Manga/OnePiece'' got his start submitting a character to ''Kinnikuman''.
** ''Manga/{{Kongoh Bancho}}'' did something similar. The author asked readers to submit ideas for characters and added many of them into the story as antagonists in later arcs.

* One of the Chess Pieces in ''Manga/{{MAR}}'' was created by a fan of the series.
* Eiichiro Oda of ''Franchise/OnePiece'' has directly stated that he writes the canon himself, and as such he will not take suggestions from the fans on this. However, he will gladly take suggestions to anything that is not canon, such as the splash pages that show the Straw Hats with animals. Fans immediately sent him a lot of suggestions, so all such pages are now derived from a reader's idea. He is also known to incorporate fan suggestions for minor character stats, usually in the form of:
-->'''JC Reader:''' "Please make [character]'s birthday [date]!"\\
'''Oda:''' "Okay."
** This also applies to mini-comics he does for his data books. One story chosen ,"RPG Time", was actually based on a idea from fan forum, ''Arlong Park'', who themselves pooled together and voted on ideas to send to him for it.
* The ''Manga/{{Toriko}}'' manga and anime has featured several beasts/ingredients which were the winning entries of contests to design them. The manga goes so far as to actually credit the designer of the beast/ingredient.

[[folder: Comic Books ]]
* Within a loose view of the ComicBook/DisneyDucksComicUniverse canon, certain ideas or fancomics submitted to official creators' blogs and heartily approved by said official creators ''have'' got some credit, and are treated as such on [[TheWikiRule the Wiki]].

* ''ComicBook/PatsyWalker'' also incorporated costume submissions from fans.
* ''Franchise/MyFriendIrma'' also incorporated costume submissions from fans.

* In ''FanFic/MassEffectTheEquestrianEquation'' and its (canceled) sequel, ''Shades of Twilight'', in true MassEffect fashion, a choice is presented at the end of each chapter that readers could vote on which decision the protagonist would make, letting the fans decide the outcome of the story.
* In ''FanFic/DividedRainbow'', several of the Sicklefin gangsters were submitted by fans.
* In ''Fanfic/ConnieAndTheBTeam'', [[spoiler: the Omega Colony gems are all fan-created OCs.]]

[[folder: Film ]]

* In ''Theatre/AFunnyThingHappenedOnTheWayToTheForum'', at one point Pseudolus pretends to be a FortuneTeller to distract Erronius. He will sometimes turn to the audience and ask for help.
* Jet Jaguar in the film ''Film/GodzillaVsMegalon'' was based on a character created by a contest winner.
* The film ''Film/GodzillaVsBiollante'' was based on a fan-submitted story idea written by a dentist.
* The two drawings in ''WesternAnimation/ThePowerpuffGirlsMovie'', Bubbles's crayon drawing of the Professor and the wanted poster of him and the girls, were the winners of a contest Cartoon Network held in conjunction with its production.
* In ''Film/TronLegacy'', Sam is briefly stuck in gladiator-style games with other programs, with other programs in the audience cheering on the contestants, as well as [[TheDragon Rinzler]]. The chanting was recorded at a panel held for the film at San Diego [=ComicCon=] using the audience.


[[folder: Literature ]]

* Creator/LFrankBaum reportedly got the ideas for many of the later books in the Literature/LandOfOz series from fans who wrote him letters.
* In the ''Literature/RainbowMagic'' series, readers voted on Mia the Bridesmaid Fairy and Juliet the Valentine Fairy's names.

* Author Derek Landy of the series ''Literature/SkulduggeryPleasant'' created a competition to submit a character during the writing of installment five, ''Mortal Coil''. Charlie Smith won, and his character, Geoffrey Scrutinous, was included in it and subsequent books.

[[folder: Live Action TV ]]

* ''Series/DirtyJobs'' relies on viewers to submit suggestions for jobs to cover. Every episode ends with a clip of Mike Rowe (usually covered in muck) asking for viewers to send in suggestions.
* The ''Series/{{Mythbusters}}'' requested socks for the Knock Your Socks Off Myth (was originally going to be the "Lost Socks in the Dryer" myth, but they changed their minds). This is in addition to all of the unsolicited items sent in by fans. Many myths to test are suggested by fans on their forum. Most of the retests are based on users in the forum, the exception being the re-retest of the Archimedes death ray requested by UsefulNotes/BarackObama.
* ''Series/BluePeter'' often has contests which ask viewers to submit ideas (such as costume designs or characters) for Creator/{{BBC}} shows or the program's own productions, with the prize usually being having their entry actually featured. (Sadly for older viewers and non-Brits they tend to only be open to UK residents under the age of 15).
** The monster from the ''Series/DoctorWho'' episode [[Recap/DoctorWhoS28E10LoveAndMonsters "Love & Monsters"]] was from the winner of a ''Blue Peter'' contest. (''Blue Peter'' also ran a similar competition back in during the late Patrick Troughton era circa 1969, but the winning monster only appeared on ''Blue Peter'', not in ''Doctor Who'' itself.)
** The half-a-TARDIS-console-room used by Idris and the Doctor in [[Recap/DoctorWhoS32E4TheDoctorsWife "The Doctor's Wife"]] was also designed by a ''Blue Peter'' contest.
* In a different ''Series/DoctorWho'' example, the audio soundtracks of the episodes that were [[MissingEpisode junked by the BBC]] survive thanks to audio recordings made by fans from the original broadcast, which were later returned to the BBC archives. Uniquely, the only colour copy of episodes 2-7 of "The Ambassadors of Death" is an early home video recording made from the story's original US broadcast by a Canadian fan, which is of low quality but was used in the story's DVD reconstruction.
* The short-lived 2009 comedy ''In The Motherhood'' depended on real life stories submitted by viewers for its scripts. It lasted for 7 episodes.
* ''Series/KamenRiderDouble'' had a contest to determine the monster for the annual Hyper Battle DVD. The winner, the The Oyakodon Dopant, even plays into the show's DetectiveDrama nature by having the Dopant challenge the heroes to identify his ingredients, leading to an ''Series/IronChef''-style cook-off between the heroes.
* Each episode of ''The Loretta Young Show'' was based on various fan letters she had received.
* ''Series/BeakmansWorld'' ran on science questions submitted by kids.
* In 2006, [[Series/TheColbertReport Stephen Colbert]] did a parody of the "Star Wars Kid" in front of a green screen as part of one of his "Better-Know-A-District" segments. After fans started making their own videos using this footage to put Stephen in different situations, he decided to hold a contest (known as the Green Screen Challenge) to see who could come up with the best video...which Creator/GeorgeLucas himself entered (and got 2nd place).
* The story for the ''Series/PunkyBrewster'' episode "Cherie Lifesaver" was submitted by a young viewer. It was also nominated for an Emmy.
* In the third season of the game show ''Series/YouDontSay'', the names and clues used on the bonus board were furnished by home viewers.
* ''Series/DinersDriveInsAndDives'' visits restaurants suggested by viewers. In fact, the suggestion form asks that you be available for interview if they decide to visit the place you recommend.
* ''Series/{{Bewitched}}'' had the episode "Sisters at Heart" written by several inner city school kids that touched on racial issues. The writing staff only added content to ensure the episode met standards and practices and was of appropriate length. All changes were approved by the students.
* ''Series/StarTrekTheNextGeneration'' accepted fan-written spec scripts throughout its run. Four actually made it into production: "The Bonding," "Measure of a Man," "The Offspring" and "Tin Man." Two other episodes were based on stories supplied by a fan.

[[folder: Magazines ]]

* In addition to fanart printed in the Mailbox section, ''Magazine/DisneyAdventures'' would occasionally run a contest like this. Notable instances were the heroes and villains contest, the winner(s) of which got a comic devoted to their creation.
* ''Boys' Life'' had a contest in which readers would submit fanart of their mascot, Pedro the Mailburro, visiting other time periods, to help inspire a new storyline for his comic, ''ComicStrip/TheWackyAdventuresOfPedro''. The winning picture had a crack in Pedro's mirror-turned-time machine send his top and [[DetachableLowerHalf bottom halves]] to AD 71,000 IO and AD 2 Tarentum, Italy, respectively.


[[folder: Music ]]

* Music/BarenakedLadies had a contest for people to send in video of them lipsynching to their song "Wind it Up", and [[http://youtu.be/4yIyumRRJkA various clips were made into the video]].
* Music/{{Placebo}}'s music video for their cover of Music/KateBush's "Running Up That Hill" is made of clips from videos of fans lip-synching.
** Feeder did something similar for one of their singles.
* The cover of Music/SonicYouth's ''Washing Machine'' is a picture sent in by a fan.
* In 1986, MTV sponsored a contest called "Make My Video" in which viewers were encouraged to send in a video set to {{Music/Madonna}}'s then recent single "True Blue" (from the album of the same name). [[OrSoIHeard Evidently]], one day was dedicated to playing all of the submitted videos until the winning entry was announced. It was then shown until Madonna's official video for the song debuted.
* There are two official videos for "Missed the Boat" by Music/ModestMouse, the [[http://www.youtube.com/watch?v=JP_jaogKAdM winning video from a fan competition]] and a [[http://www.youtube.com/watch?v=O4XskfT6vNY video featuring clips of several submissions]] to the contest.
** The winners of the contest, a duo of film-makers who go by the name "Walter Robot", later became [[PromotedFanboy professional music video directors]] due to the attention the contest received for them. They've gone on to direct videos for Music/DeathCabForCutie, Music/{{Underoath}}, and [[http://en.wikipedia.org/wiki/Walter_Robot several other artists]].
* Music/RedHotChiliPeppers had a contest in 2007 for fans to make their own video for "Charlie". The winning entry became the official video for the song and appears on their official Youtube channel. This despite the fact that the proposed single release was cancelled.
** On their 1998 tour they played a song called "Bunker Hill", which they went on to attempt in the 'Californication' and 'By The Way' sessions, but were never completely happy with it, so a studio version didn't get released. Over this time, fans were constantly asking them about this song. Eventually they decided to remix it to their liking (with a new bassline) and put it out as the B Side of Fortune Faded in 2003.
* The ''Dick's Picks'' series of audience recordings of Music/TheGratefulDead concerts.
* Music/OKGo's song "I'm Not Through" was the subject of [[http://www.talenthouse.com/saatchi-and-saatchi-ok-go-video-challenge this music video contest]] -- [[http://www.youtube.com/watch?v=47PDFwMcplw the winning video]] in particular is a very OK Go-ish [[TheOner Oner]].
* Pretty much all of Music/VelvetUnderground's officially released live albums save for their 1993 reunion are made up of fan recordings.
* For Music/{{Korn}}'s 1999 album ''Issues'', the band held a fairly high profile fan submission contest for the album's cover art, resulting in the top 4 being released as official album art.
* Both the cover art and title of Music/{{Weezer}}'s ''Maladroit'' were submitted by fans - the cover was created by a fan for an official contest, while the title was a suggestion made in a less formal thread on the band's official forum asking for album name ideas. They also had fans contribute to the songwriting process less directly: The band would post demos of songs they were considering for the album, and would take fans' reactions into consideration when arranging songs, as well as letting them influence which songs appeared on the album to some extent.
* Music/TheBeastieBoys' live DVD ''Awesome:I Fuckin' Shot That!'' was created by lending audience members camcorders at a show and cutting together the best footage.


[[folder: Tabletop Games ]]

* ''TabletopGame/MagicTheGathering'':
** ''Magic'' has held a "You Make the Card" event four times, allowing players to submit and vote on cards that would eventually become [[http://www.magiccards.info/autocard.php?card=Forgotten+Ancient Forgotten Ancient]], [[http://www.magiccards.info/autocard.php?card=Crucible+of+Worlds Crucible of Worlds]], [[http://www.magiccards.info/autocard.php?card=Vanish+Into+Memory Vanish Into Memory]], and [[http://magiccards.info/query?q=%22Waste+Not%22 Waste Not]].
** The now-discontinued annual [[http://wiki.mtgsalvation.com/article/Magic_Invitational Magic Invitational]] tournament invited the game's top players to compete for the chance to submit their own custom card to the game and get their face featured in its artwork. Since the Invitational players included some of the best in the world, many of these cards turned out to be tournament powerhouses, like [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=83771 Dark Confidant]], [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=49434 Solemn Simulacrum]], and [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=227676 Snapcaster Mage]].
** For ''Magic 2015'', Wizards solicited card designs from several pillars of the gaming community, including [[VideoGame/{{Minecraft}} Markus Persson]], ''Webcomic/PennyArcade'', [[Creator/GearboxSoftware Mike Neumann]], Creator/EdmundMcMillen, [[VideoGame/PlantsVsZombies George Fan]], [[VideoGame/LeagueOfLegends Stone Librande]], James Ernest (Cheapass Games, [[TabletopGame/{{Yomi}} David Sirlin]], [[VideoGame/{{Psychonauts}} Brad Muir]], [[VideoGame/{{Ultima}} Richard Garriott]], [[Creator/StoneBladeEntertainment Justin Gary]], [[VideoGame/GuildWars Isaiah Cartwright]], [[VideoGame/WorldOfWarcraft Rob Pardo]], and [[Creator/InterplayEntertainment Brian]] [[Creator/InxileEntertainment Fargo]].
* The 1e ''TabletopGame/DungeonsAndDragons'' book ''Fiend Folio'' was mostly composed of submissions to the "Fiend Factory" column in ''Magazine/WhiteDwarf''.

[[folder: Toys ]]
* Franchise/{{LEGO}} loves doing this for the ''Toys/{{Bionicle}}'' franchise. They've used these sort of contests to establish a variety of [[CallARabbitASmeerp Rahi]] species, [[BountyHunter Dark Hunters]] and the character Toa Krakua. These were published in the LEGO Magazine, in guide books, or online.
** A number of them had a surprisingly prominent presence in the story. Though none were immune to being KilledOffForReal, as Ancient and Guardian can tell you. LEGO was also fond of letting the fans design already official but previously unseen characters, either as fan-made LEGO figures or as drawn artwork, which then received official status. Certavus, Surel, his Iron Wolves and Toa Nikila are just a few of these. The Agori villager named Kyry is an interesting case, however: a fan-built model of him was declared canon, but when he appeared in a comic, he looked nothing like the model due to the miscommunication between the writers and the comic artist.
** [[https://ideas.lego.com/ LEGO Ideas]] (formerly CUUSOO) is an official channel (currently in open beta) where fans can submit their designs for models and vote on which ones they'd like to see enter production. Fan designs that get 10,000 user votes are sent to LEGO's team for consideration.
* Hasbro did it sometimes in the last years with ''Franchise/{{Transformers}}''.
** The first time was in 2013, when they made a poll to allow people to create a new character choosing between various options in a poll (faction, name, gender, weapon, altmode, color scheme, special abilities, origin place and characterization). The final result was [[http://tfwiki.net/wiki/Windblade_%28G1%29 Windblade]].
** The second time happened in early 2015, this time to make an entire combiner to tie in with the ''Combiner Wars'' subline. This time the poll options were slightly more restricted, in particular because this time the various characters forming the combiner had to be retools of preexistent character molds from the first 2-3 waves of the toyline. This time we got [[http://tfwiki.net/wiki/Victorion Victorion]] as our final result.
** The third time was in late 2015 and it was a smaller thing: rather than create a new character, fans had to vote to choose who was going to be the fourth Titan class figure in the ''Generations'' line after Metroplex, Devastator and Fortress Maximus, choosing between Omega Supreme, Trypticon and Scorponok. Trypticon won.
** It happened again in early 2017, allowing fans to choose who will become a Prime in the future IDW comics and get a figure in the third subline of the ''Prime Wars'' trilogy (known as ''Power of the Primes''): the contendants were Arcee, Ultra Magnus, Hound, Megatron, Shockwave, Star Saber, Optimus Primal, Thunderwing and "Unknown Evil"[[note]]Later confirmed to be Deathsaurus[[/note]]. Optimus Primal won.
* ''Toys/TheTrashPack'' has had "Design Your Own Trashie" contests, where the winners get their design made into an exclusive Trashie figure.


[[folder: Video Games]]

* While still under development, ''VideoGame/TheElderScrollsOnline'' had fans send in suggestion for the name of a Dunmer in the game.
* Occasionally, Creator/{{Capcom}} would hold a contest asking for drawings of Robot Masters to be in the next ''VideoGame/MegaMan'' game. Most were held in Japan, except for ''VideoGame/MegaMan6'', which was an American tie-in with ''Magazine/NintendoPower'' that gave us Wind Man and Knight Man.
** This was also done with ''VideoGame/MegaManLegends 3'', where the fans helped out with ideas and with choosing character designs. Unfortunately, the game ended up canceled.
** ''VideoGame/MightyNo9'' appears to be a spiritual successor in this regard, such as choosing Call's character design and designing an enemy.
*** [[spoiler: The fans took it a step further with making sure that one of Call's designs would still make it into the final game. This design, Design D, would be used as the overall design for the FinalBoss Trinity]].
** The tradition continued in the ''VideoGame/MegaManBattleNetwork'' games, with most of Mr. Famous's [=NetNavis=] being fan-made, as well as a few of the plot-relevant bosses, like [=JudgeMan=].
*** The same goes for the sequel series, ''[[VideoGame/MegaManStarForce Star Force]]'', with fan-designed {{Bonus Boss}}es appearing in the second and third game.
** The VideoGame/Nintendo3DS version of the ''{{VideoGame/Mega Man|Classic}} [[CompilationRerelease Legacy Collection]]'' contains exclusive Challenge Mode levels submitted by the fanbase, which complement the existing Challenge Mode levels and are unlocked using the Mega Man Toys/{{amiibo}}.
* On multiple occasions, ''VideoGame/{{RuneScape}}'' has solicited fan ideas for content. The pub in southeast Ardougne, for example, was designed and voted on by players, and the name of the sea monster Thalassus from the "Deadliest Catch" quest was suggested and selected by the public.
* ''VideoGame/TeamFortress2'' has added fan-created "community" weapons to the list of items that can be found during game.
** Several fan-created maps were also added to the official list of maps.
** This concept has been since expanded into the "Steam Workshop", which is also available for several other games. [[note]]Most titles that use the Workshop system use it as a way to streamline game mod installation (Killing Floor, Skyrim) or to share content made ingame (Scribblenauts, Portal 2). ''[=TF2=]'' however, uses it as a way to submit content to Valve for approval and possible official release. Recently the [=TF2=] workshop has been doing something similar to the ''VideoGame/CounterStrike: Global Offensive'' workshop, by providing a separate section where players can add custom maps to the game.[[/note]]
* After the developers made modding tools for ''VideoGame/WorldInConflict'' available to gamers, several fan-created multiplayer maps have been distributed via Massgate, along with official maps.
* Free Software/Open Source games like ''VideoGame/OpenArena'' and ''VideoGame/{{Nexuiz}}''[=/=]''VideoGame/{{Xonotic}}'' are composed entirely of fan-made content.
* In ''VideoGame/KingdomHearts'', a contest was held where the winning fan would get to name one of the upcoming game's special super-bosses. The winner was a boy named Kurt Zisa, who promptly named the boss after himself.
* Since ''VideoGame/CityOfHeroes'' has gone with their "hybrid model" and opened the micro-transaction store, they've added at least two costume sets that were explicitly conceived by fans. On top of that, for its entire run many of the added features (new powersets/archetypes, costumes, etc.) were developed in-house, but based on the most popular requests in the forums.
* Several mods for ''VideoGame/WorldOfWarcraft'' became so popular among the players that Blizzard ended up implementing their own version into the core game.
* Each game in the ''[[VideoGame/{{X}} X-Universe]]'' series has an add-on Bonus Pack by forum member Lucike, containing a group of [[GameMod scripts]] to make players' lives easier, digitally signed by Egosoft so your savegame doesn't get marked as [[NoFairCheating ***modified***]]. Additionally the ''[[LimitedSpecialCollectorsUltimateEdition X-Superbox]]'' series collection includes three fan-made soundtracks, additional signed scripts, and PDF versions of fan fiction from the forums. ''And'' [[http://www.egosoft.com/x/xnews/201212_1_44News.html the 3.0 patch (scroll down a ways)]] for ''X3: Albion Prelude'' is be largely composed of content written by the [[http://forum.egosoft.com/viewtopic.php?p=3962964 AP Community Project]], a group of high-profile ''X'' modders.
* The art book that comes with the ''StreetFighter 25th Anniversary Collector's Set'' is comprised entirely of fan-made artwork. The collection also includes two discs of fan-made music remixes.
* ''VideoGame/StarWarsGalaxies'' did this often. Sony often held contests on the official forums that subscribers could enter. Not only would the winners have their artwork or stories featured in the game, but it had the added benefit of making these fan submissions official ''Franchise/StarWarsExpandedUniverse'' canon.
* ''VideoGame/DwarfFortress'' has a large sub-forum for suggestions that the creator is known to frequently read, but the only ''confirmed'' example of this trope was when a number of players got together and provided some numbers for -among other things- correct tensile strengths and molar hardness of various metal alloys and the real-life mass and density of ''sand''. [[note]]The slightly optimised graphics implementation that to this date remains the only third-party content added to the game's actual code doesn't quite count, as the fan who submitted them is also Toady One's webmaster.[[/note]]
* Creator/BioWare held a competition during the production of ''VideoGame/SonicChronicles: The Dark Brotherhood'' which let the fans name one of the alien races seen later in the game. The winning name was Zoah, a reference to ''VideoGame/PanzerDragoon''.
* Subverted in the case of ''VideoGame/SonicAndSegaAllStarsRacing'', where a piece of fan art of [[WesternAnimation/SonicUnderground Sonia]] was mistaken for official art of [[StalkerWithACrush Amy Rose]], and used as a texture in the Wii version of the game. The offending texture was removed in later print runs once it was caught, and [[DummiedOut removed via patch]] from the [=PS3=]/360 release.
* In the first three UsefulNotes/GameBoyAdvance titles for ''Manga/BoboboboBobobo'', many of the [[TheMook enemies]] you fight are submitted fan characters.
* This is one of ''VideoGame/SoundVoltex''[='=]s major gimmicks. The ''Sound Voltex Floor'' campaign allows fans to submit their own songs for inclusion within the game. Many submissions in ''Sound Voltex Booth'' are remixes of existing Music/{{BEMANI}} songs, although artists have started submitting more original songs, especially in ''Sound Voltex II''.
* ''TNT: Evolution'', part of ''Final Doom'', was originally a fan creation. However, the mappers, TeamTNT, were approached by id Software to have the megawad published. This was met with some controversy because the megawad was going to be a freeware release.
* ''VideoGame/EternalDarkness'' SpiritualSuccessor ''Shadow of the Eternals'' is using this as a key part of its business model, with portions of its forums devoted to ideas from fans to help construct its world-building.
* In the fall of 2013, ''VideoGame/AgeOfEmpiresII'''s fanmade expansion ''[[http://www.forgottenempires.net/ Forgotten Empires]]'' [[http://www.gamechup.com/aoe-2-gets-an-official-expansion-after-14-years-forgotten-empires/ shall receive official expansion status]] for the UpdatedRerelease.
* ''VideoGame/StarTrekOnline'' has the Foundry, an in-game LevelEditor that allows players to code and submit their own missions that are then playable in the main game from a submenu. Foundry missions pay out varying amounts of dilithium based on the average length of time it takes players to beat them. Cryptic set up a similar Foundry for ''STO's'' younger sister ''VideoGame/{{Neverwinter}}''.
* In ''VideoGame/{{Academagia}}'', the developers have included many player-written Adventures and Events as part of {{DLC}}s.
* The [[GameEngine Unreal Engine 4]] reboot of [[VideoGame/{{Unreal}} Unreal Tournament]] is being developed by both Creator/EpicGames themselves and the Unreal community, furthering this trope.
* ''VideoGame/MassiveChalice'', a Website/{{Kickstarter}} funded game, allowed backers (above a certain level) to construct their own blood-lines. Allowing the creation of standards, house colours, character names, mottoes and battle-cries. These where then split into thematic and non-thematic content. Allowing the player to choose to live with content that adds to the immersion of the game and stuff that will probably make you laugh (you can of course choose both if you want a mix).
* Another Music/OKGo example: Their song "White Knuckles" was subject to a fan mix contest, with the winner (Big Robot Remix) being added to ''VideoGame/RockBand'' via [=RBN=].
* The Festivalist dressphere from ''VideoGame/FinalFantasyX2'', for each of the three girls, was based off of drawings by a very young Japanese fan of the series as part of a contest advertised in ''Final Fantasy X-2 Ultimania''.
* There's a whole category in ''VideoGame/{{Warframe}}'' for skins, both weapons and armors, and helmets, created by fans, called "[=TennoGen=]" in-game.
** Quite a sizable chunk of the game content, from warframes like Chroma to weapons like the Mios, were originally fan-submitted designs circulating the forums before being introduced in the game.
* The developers of ''VideoGame/ProjectZomboid'' are very supportive of their prolific modding community, and they've even found some mods worthy of folding back into the base game. Features to randomize or save your character build are an example, but the most visible is the Erosion mod that causes the environment to gradually overgrow and deteriorate over time.
* ''[[{{VideoGame/PAYDAY2}} PAYDAY 2]]'' has followed in the footsteps of [=CS:GO=] and allows players to make their own skins for the weapons in the game, then submit them to the Steam Workshop for peer review, in hopes of getting them into the next Safe, thus making them available in-game. In addition, multiple fan-made 'quality of life improvement' mods have been implemented into the game itself, such as [=HoxHUD=]'s cheater labelling system.

* ''Webcomic/{{Drowtales}}'' writers' have created the system, where in to fill the ever increasing cast of character in their chapters, readers can pay to have their own original characters[[note]] Who most fit into Drowverse canon[[/note]] inserted into the story, to fulfill rules as extras, mooks or full on side characters.
** While it does help the comic financially and creatively, it has created an obvious system where unnamed or minor side characters are going to be the [[RedShirt victims of the plot]], but paid characters [[MauveShirt usually survive without major harm]], sometimes unexpectedly so.
* This ''used'' to be the case for ''Webcomic/BittersweetCandyBowl'', but Veronica was having problems when people wanted their characters taken out of the work, thus, she no longer puts ''any'' {{OC}}s into the comic.
* In one story arc for the Martian theme in ''WebComic/IrregularWebcomic'', the Martians force Ishmael out of his room so they can use his computer to invade the world, with no reason given other than, "We have to start somewhere." The actual reason for this is given in [[http://www.irregularwebcomic.net/ a winning]] CaptionContest entry, where the Martians are trying to bid on a Doomsday Machine at Website/{{eBay}}. Of course, not all of the submitted entries revolve around their invasion plan, with some entries having the Martians use the computer for other purposes.
* {{Supervillainous}} does this a lot

There's also [[https://www.youtube.com/watch?v=abYKKrCkF-c 'A Day in the Life of DarkSydePhil']], reenacting [[Creator/TheKingOfHate Phil's]] inability to do the most basic actions in games and his habit of blaming everything but himself, only applied to real life situations.
* Many games crowd-funded on Website/{{Kickstarter}} or similar sites offer the option of submitting content as perks for backers. Generally, this is something minor like naming [=NPCs=].
* Creator/RoosterTeeth held a contest for ''WebAnimation/{{RWBY}}'' where fans were asked to design Velvet Scarlatina's battle gear. [[https://twitter.com/RWBYwiki/status/442459177491763201/photo/1 This was the winning design]].

* The ''WesternAnimation/{{Beetlejuice}}'' ep "Brides of Funkenstein" was written by young fans.
* ''WesternAnimation/DextersLaboratory'' has an episode, "Dexter and Computress Get Mandark!", that looks like it was animated by a small child. The story was written, and narrated, by a young fan.[[note]]with help from his mother[[/note]]
* The ''WesternAnimation/TinyToonAdventures'' ep "Buster and Babs Go Hawaiian" was written by young fans. Naturally, when Buster [[WhoWritesThisCrap complains about the quality of the episode]], he likens it to [[LeaningOnTheFourthWall being written by 13-year-olds]].
-->'''Babs:''' 13-year-olds ''did'' write it.\\
'''Buster:''' Oh, well, that explains it.
* The ''WesternAnimation/AdventureTime'' episode “Jake vs. Me-Mow” featured a new character (Me-Mow) based on a drawing made by a young fan (used as the episode’s title card).
* The ''WesternAnimation/EdEddNEddy'' episode "Here's Mud In Your Ed" was inspired by Kit Topp, web-mistress of an ''Ed, Edd 'n' Eddy'' fan-site.
* ''WesternAnimation/PoundPuppies2010'' had an episode with a puppy named Cinnamon. Wonder how that puppy got that name? Viewers had to vote for the name online.
* Season 2 of ''WesternAnimation/WanderOverYonder'' introduced the "Galactic Villain Leaderboard" and Lord Hater's struggles to move to the top of the board. Many of the names on the board, [[http://suspendersofdisbelief.tumblr.com/post/130116534851/the-wander-over-yonder-galactic-villain as posted on story designer Frank Argones's Tumblr blog]], are taken from OC villains created by fans.
* When the second season of ''WesternAnimation/{{Futurama}}'' was being localized for Germany, suggestions for the episode titles were collected on de.rec.tv.futurama. And yes, several of them were actually used. They never did something like this again, however.
* The creators of ''WesternAnimation/SouthPark'' asked the fans to create RuleThirtyFour fanart (yaoi specifically) involving Tweek and Craig, to be later included in an episode.
* The ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode, "Keep Calm and Flutter On" was written by [[http://intensedebate.com/people/TeddyAntonio Teddy Antonio]], who on [=IntenseDebate=] claims to be a fan who met Meghan [=McCarthy=] (the story editor of Season 3).
* The staff at ''WesternAnimation/{{Arthur}}'' have poached Facebook for episode ideas, resulting in such episodes as "The Tattletale Frog" and "D.W. and Bud's Higher Purpose."
