When an established existing medium ventures into the ExpandedUniverse, writers will often rely heavily on familiar characters and past storylines from the official {{canon}} to ensure that fans of the original material are happy. Unlike the original canon, however, an "expanded universe" adaptation also gives the writers freedom to introduce new, "never before seen" characters, as the production staff enjoys their newfound liberation from whatever codes and limitations ruled the original work.

Often, these new characters will be added to fill a particular need in the new story, and add some degree of novelty to attract readers/watchers. Frequently, they'll also fill some gap in the current cast, such as adding a female character to an all-male cast, or [[TokenMinority imposing some other element of diversity, be it racial, geographic, or simply personality]]. This can spark new conflicts and adventures that wouldn't otherwise occur under the limitations of the "conventional" cast and series format — one of the main points of "expanded universe" fiction to begin with.

Depending on how well the character fits into the adaptation or how much the fans like the character, Canon Foreigners can either be much beloved or much hated, and if popular enough, may be {{Ret Canon}}ed into the official canon where they are known as {{Canon Immigrant}}s.

FillerVillain is a SubTrope of this.

Compare OriginalGeneration characters, who are Canon Foreigners to several canons at once in a {{Crossover}} plot. Also compare to OriginalCharacter.

Contrast AdaptedOut, where a character in the source material is omitted in the adaptation.

See GodCreatedCanonForeigner when this character comes from the original creator.

[[folder:Anime & Manga]]
* All seventeen of the ''Franchise/DragonBall'' [[NonSerialMovie movies]], apart from ''Mystical Adventure'' and ''The Path to Power'', featured original characters who were never seen in the original manga, although Garlic Jr. from ''Anime/TheDeadZone'' did appear in an [[FillerArc anime-only story arc]] in the TV series, as did Gohan's pet dragon from ''Anime/TheTreeOfMight''.
** While Bardock from the TV special: ''Bardock - The Father of Goku'' [[CanonImmigrant briefly cameos in the manga]]; several of his allies and enemies who starred in the special do not.
** The eighteenth movie features Beerus and Whis, two {{Canon Immigrant}}s.
* Ashil from the ''Manga/ShamanKing'' anime. And the Lily Five, who became surprisingly popular among the fans.
* The Aliens and the Makaiju in the first arc of ''Anime/SailorMoon R'', the similarly themed Fiore in the ''Anime/SailorMoon R'' movie and Perle & the villains from the ''Anime/SailorMoon [=SuperS=]'' movie. Also Yūichirō, Rei's love interest.
* Kiyone from ''Anime/TenchiMuyo'' was added in the TV version as a StraightMan foil for Mihoshi. She has since become one of the more popular cast members, but ''never'' featured in the original {{O|riginalVideoAnimation}}VA canon, where her name is used for a completely different character.
** She has a ''{{counterpart|Comparison}}'' in the third OVA in Noike; the green-haired, no-nonsense former partner of Mihoshi.
** She is also in the semi canonical Mihoshi Special (Which in canon is Mihoshi telling a story which may or may not be based on real events) and the movie Daughter of Darkness which takes place in the OVA continuity.
%%* Meiling from the ''Anime/CardCaptorSakura'' anime.
%%* Kitazawa Ken, Professor Utonium's son from ''Anime/DemashitaPowerpuffGirlsZ''.
* Sasuke Sarugakure, the ninja servant of the Kunō family in the ''Manga/RanmaOneHalf'' anime, is at least a semi-regular character who never appears in the original manga. On his first appearance, he did the actions originally done by Gosunkugi, a character oddly removed from the anime at first, and introduced much later. There are [[http://www.furinkan.com/ranma/characters/minoranime.html a number of other anime-only characters]], but few of them appear in more than one episode.
* The ''Anime/RebuildOfEvangelion'' movies feature two Angels not seen in [[Anime/NeonGenesisEvangelion the original TV series]]. There's the snake-like Third Angel that Mari faces at the beginning of the second film, as well as the unnamed Angel that Asuka {{curb stomp|Battle}}s during her debut.
* Liu Kowloon, Eva Durix, Oni-Maru and Alexander the [[NonHumanSidekick flying squirrel]] from the ''VideoGame/VirtuaFighter'' anime series.
* The ''VideoGame/FatalFury'' anime movies had Lily [=McGuire=], Tony and his mother Elsa in the TV specials, as well the Gaudeamus siblings Sulia and Laocorn, Panni, Hauer and Jamin in ''[[TheMovie The Motion Picture]]''.
** Lily does make [[TheCameo a cameo]] in the Mexico stage of ''VideoGame/TheKingOfFighters '94'' (alongside other SNK characters), and, as they were love interests [[spoiler: and [[TheLostLenore Lost Lenores]] ]] to Terry in their respective appearances, both Lily and Sulia are mentioned by him in ''Days of Memories'', an AU DatingSim series featuring several SNK [=IPs=].
* The ''VideoGame/ArtOfFighting'' TV special only had one, Ray. Sadly Ray [[CListFodder wasn't long for this world]], though [[VideoGameMoviesSuck with this movie]] he probably was better off.
* Homura, the BigBad of the second season of ''Gensoumaden Manga/{{Saiyuki}}'', and his two henchmen, Zenon and Shien. Homura didn't make it to CanonImmigrant status, but original manga-ka Minekura Kazuya did write and illustrate an [[BonusMaterial Omake]] chapter about him.
* The characters Crys Mu, Dark Mu and Hattori Kinzo in the ''Franchise/TeenageMutantNinjaTurtles'' OVA series.
* Barasuishou, the second BigBad of the ''Manga/RozenMaiden'' anime, who replaces the manga's Kirakishou. [[spoiler:Well, not ''entirely''...]]
* ''Anime/VariableGeo'': While Satomi enters the tournament of her own free will in the ''[[VideoGame/AdvancedVariableGeo Advanced V.G.]]'' game series, [[TheAnimeOfTheGame the OVA]] makes it so she's [[AnOfferYouCantRefuse blackmailed into it]], by introducing several all new characters:
** Damian is cast as [[spoiler: [[BigBad Miranda Jahana]]]]'s [[TheDragon most trusted employee]] and is the one who discovers Satomi's latent fighting potential. Which convinces him that she'd make the ideal [[spoiler: [[GrandTheftMe vessel]] for Miranda's [[TheDisembodied disembodied spirit]]]].
** Siritahi is also exclusive to the OVA and is a lab technician at the Jahana Research Facility, who provides Damian with medicated injections to help him [[spoiler: control his [[SuperpoweredEvilSide alter ego]]]].
** The [[BadassAndChildDuo Old Man and the mute girl with him]] aid [[TheProtagonist Yuka]], by saving her and her friends from [[spoiler: Damian]] in the second episode. Then imparts her with words of wisdom to help her find the strength she'd need to save Satomi.
** Washio serves as Reimi's [[RighthandHottie personal aide and adjutant]], who helps her by uncovering the goings-on at the research facility. Which is how Reimi learns that Damian's been secretly working for [[spoiler: her mother]].
* ''[[Manga/FullmetalAlchemist Fullmetal Alchemist: Brotherhood]]'' introduces a brand-new AntiVillain for the first episode; Isaac [=McDougal=], the Freezing Alchemist, who mostly just exists to establish the setting, and drop loads of {{Foreshadowing}}.
** The [[Anime/FullmetalAlchemist 2003 Anime]], due to its [[AlternateContinuity divergent nature]] that came to be when it OvertookTheManga, had even more of these. The most prominent ones were [[SmugSnake Lt. Col. Frank Archer]], Lyra, Dante, and the show's versions of Wrath and Sloth. TheMovie ''[[Anime/FullmetalAlchemistTheConquerorOfShamballa Conqueror of Shamballa]]'' adds Noah and several others.
** ''Brotherhood'' NonSerialMovie ''[[Anime/FullmetalAlchemistTheSacredStarOfMilos The Sacred Star of Milos]]'' literally adds a canon foreign country.
* Anime/SonicTheHedgehogTheMovie has three: Sara, the President, and Old Man Owl.
** ''Anime/SonicX'' featured more Canon Foreigners than characters from the games. Most notably are the Thorndyke family, Eggman's crew, Cosmo and Dark Oak.
* ''[[VideoGame/StarOceanTillTheEndOfTime Star Ocean: Till the End of Time]]'': Pierre and his big sister, Kurin, are exclusive to the manga adaptation. They're [[http://mangapark.me/manga/star-ocean-till-the-end-of-time/s1/v4/c16.5/2 a child duo]] of bounty hunters from the Sanmite Republic, who are initially [[QuirkyMinibossSquad minor]] [[http://mangapark.me/manga/star-ocean-till-the-end-of-time/s1/v3/c0/149 antagonists]] to Fayt, Nel, and Cliff. But they eventually seek Pierre [[http://mangapark.me/manga/star-ocean-till-the-end-of-time/s1/v6/c24/39 for his ability to control beasts]], to help them capture Crossel.
* The 1986 ''Franchise/SuperMarioBros'' anime film has Princess Peach's fiancee, Prince Hal of the Flower Kingdom ([[DieForOurShip Peach/Mario fans don't have to worry about him showing up in any future game]]).
* Many of the star trainers from ''Manga/PokemonSpecial'' are taken directly from the main game series (Blue herself existed as a MythologyGag), yet [[{{Bifauxnen}} Yellow]] and [[TheNapoleon Emerald]] are the only ones with no canon video game equivalents.
** And given [[WalkingTheEarth the]] [[LongRunners nature]] of [[Anime/{{Pokemon}} the Anime]], there are [[LoadsAndLoadsOfCharacters numerous]] recurring characters not based on any original game characters, the most notable being [[TerribleTrio Jessie, James and Meowth]], who were [[CanonImmigrant given green cards]] in [[RecursiveAdaptation Pokémon Yellow]].
** Pokemon manga in general have many characters who aren't counterparts to any in the games.
* Miyu Edelfelt from ''Manga/FateKaleidLinerPrismaIllya'' is, thus far, the only character who doesn't have a counterpart of some sort in normal ''VisualNovel/FateStayNight'' continuity. ''Drei'' season gives us [[spoiler:the Ainsworths nd Tanaka, who presents in AlternateUniverse.]]
* The anime adaptation of ''LightNovel/{{Slayers}}'' has quite a few of these, with the standouts being Zangulus from the first season, Martina from the second, Filia, Valgaav, his [[ThoseTwoGuys henchmen]], and the guardians of [[Anime/LostUniverse the Black Orb]] from the third, and Pokota from the fourth and fifth.
** The manga adaptations that branched off even further from the novel canon also has these, namely Lyos from ''Knight of the Aqualord'' and Noah and Ranzam from ''Hourglass of Falces.'' There's also the video games, with Lark and Rynnea from the ''Royal'' games and Demia and Viola from ''Slayers Wonderful.''
* Everyone in ''Anime/TheTowerOfDruaga'' except for Gilgamesh, Ki, Succubus, and Druaga counts.
* ''Anime/YuGiOh'' has many, but one of the most notable would be Noah Kaiba; the character would be the actual son of Gozaburo Kaiba (Mokuba and Seto's foster father), who conveniently died right before Mokuba and Seto arrived at the Kaiba manor. He also looks a lot like Seto, even though they're not blood-related.
* ''Manga/InuYasha'' has a few. Ayame, a wolf-demon girl and supposed bride-to-be to Koga; Akitoki Hojo, a past ancestor of one of Kagome's classmates. Kagome's friends, Eri, Ayumi, and Yuka, could also be considered as such. While they appear in the manga only one of them (Eri) is named and they hardly have any parts to play as opposed to the anime where they're used for many a filler.
* ''Manga/MagicKnightRayearth'' has Innouva (season 1), plus Nova, Debonair and Sierra (season 2).
* ''Anime/CodeGeass'' has several due to its various spinoff manga and video games, including literal {{Evil Twin}}s Castor and Pollux from the NintendoDS game; Rai, the protagonist of the VisualNovel ''Lost Colors''; Mariel, Suzaku's {{Love Interest|s}} in ''Suzaku of the Counterattack''; Nunnally's best friend Alice and the other Irregulars from ''Nightmare of Nunnally'', and more.
* The ''[[Anime/TengenToppaGurrenLagann Gurren Lagann]]'' manga introduces Nia's eldest sister, Princess Straea, who was discarded many years ago only to have chosen to serve her father by running the all-women village for him, and now wants Nia to take her place.
* ''Anime/Persona4TheAnimation'' has the minor recurring character [[Creator/AoiYuuki Aika Nakamura]]. She's now kind of a CanonImmigrant, being mentioned by name in both ''VideoGame/Persona4Arena'' and ''VideoGame/{{Persona 4}}: [[PolishedPort The Golden]]''.
* Traditionally there are [[TheFourGods four Saint Beasts]] as was the case in ''Anime/AngelTales'' with Goh, Shin, Rey and Gai filling these roles. When ''Anime/AngelTales'' spawned a rather different {{spinoff}}, ''AudioPlay/SaintBeast'', Judas and Luca were created to be the main characters and the Saint Beasts became six instead. Also, instead of the goddess, Zeus became the head god of heaven.
* ''Anime/MarvelAnime: Anime/XMen'' had Yui Sasaki and her son Takeo, who essentially acted as [[RaceLift Japanese]] versions of Moira [=MacTaggert=] and David/Legion. There were also a few minor characters like the U-Men member Kick and Hisako/Armor's best friend Kyoko.
* ''Manga/TriGun'': Several one-shot villains in the first half of the anime, a few of which even wound up [[CanonImmigrant making cameos in the manga]], most notably Descartes. Gung-Ho Guns Caine the Longshot and Chapel the Evergreen are exclusive to the anime (although Chapel does have an equivalent in the manga).
* The numerous anime that drew from ''Manga/MahouSenseiNegima'' surprisingly do not add a lot for all of the changes they make; the most well-known immigrant was the demonic king that [[spoiler:made a DealWithTheDevil with Asuna, which ends up in her death]] from the 2005 anime adaptation.
* ''LightNovel/LoveChunibyoAndOtherDelusions'''s AnimatedAdaptation has a lot, due to the need of AdaptationExpansion and the eventual BroadStrokes treatment. In order of first appearance: resident {{sleepyhead}} Kumin, [[MrImagination Rikka]]'s older sister Touka, and BrattyHalfPint Sanae.
* ''Manga/PuellaMagiOrikoMagica'' uses this heavily, with [[AntiVillain Oriko]], [[LivingEmotionalCrutch Kirika]], and [[MoralityPet Yuma,]] the inhabitants of a mystery timeline where the titular character decided to muck with the events of the series. The [[WhatHappenedToTheMouse question]] of what happened in the other timelines would eventually be answered in a spinoff starring ''only'' Canon Immigrants.
* The Manga/CaptainTsubasa original series gives us Rika Oosawa, a half-Japanese/half-French PluckyGirl who befriends Tsubasa and the Japanese Team and acts as their tour guide when they go to France. She also appears in the non-canon movies.
* ''Anime/SaintSeiyaLegendOfSanctuary'': The false Athena. In [[Manga/SaintSeiya the original series]], the villain merely claims Athena stays inside her temple and forbids others from entering.
* In Anime/OnegaiSamiaDon (an AnimatedAdaptation of the book Literature/FiveChildrenAndIt) includes several of those, since the series is 78 chapters long. It has Anne the GirlNextDoor [[AdaptedOut who replaces Althea]] and her BumblingDad, Harry the GloryHound, the kids's neighbor Mr. Matthews, etc.
* In ''Manga/SoredemoSekaiWaUtsukushii'' there is the council of elders that Livi always consults - they do not exist (or are at least never shown) in the manga while in the anime they often appear and have no real role other than be the PluckyComicRelief. Nike's retinue of maids might count as well, as while she was attended by maids in the manga, they were not given distinctive designs, unlike the trio shown in the anime.
* ''Manga/PingPong'': Yurie, who gets introduced in the anime as Ryūichi's cousin...and [[KissingCousins girlfriend]].
[[/folder]]

[[folder:Audio Play]]
* The ''AudioPlay/BigFinishDoctorWho'' {{audio play}}s had Erimem (companion to the Fifth Doctor), Evelyn Smythe (companion to the Sixth Doctor), Hex and Raine Creevey (both companions to the Seventh Doctor), Charley Pollard (Eighth and later, at least from her point of view, Sixth Doctor companion), C'rizz, Samson and Gemma Griffen, Lucie Miller, and Creator/MaryShelley (all companions to the Eighth Doctor) all slotting in around gaps in the timeline of the TV series.
** Though in [[Recap/TheNightOfTheDoctor The Night of the Doctor]] the Eighth Doctor mentions Big Finish companions, apparently making them [[CanonImmigrant Canon Immigrants]].
* The ''AudioPlay/BlakesSeven Liberator Chronicles'' introduce the Auron scientist Gustav Nyrron, who boards the ''Liberator'' in "Solitude" and is promptly dumped at Avon's insistence. He returns in later episodes.
[[/folder]]

[[folder:Comics]]
* While Archie Comics' ''ComicBook/TeenageMutantNinjaTurtlesAdventures'' was originally meant to be a RecursiveAdaptation of the original cartoon, it eventually featured a good dozen original characters. The most prominent were allies Ninjara, Oyuki Mamishi, Ray Fillet, Jagwar, Dreadmon, and Cudley the Cowlick; and villains Armaggon, Verminator X, Null, and Maligna.
* And while we're on an Archie kick: in ''Comicbook/ArchieComicsSonicTheHedgehog'', canon foreigners outnumber characters adapted from the games or the Saturday Morning cartoon.
** ''Comicbook/SonicTheComic'' (alternately known as ''Fleetway Sonic'') also contained many canon foreigners, supposedly based on the various critters released from Badniks in the first Sonic game, such as Johnny Lightfoot (a rabbit) and [[PunnyName Porker Lewis]] (a pig). It also included squirrel turned invincible Badnik "Shortfuse the Cybernik", and a whole legion of MechaMooks known as "Troopers".
*** The rarely seen Sonic manga released by Shogakukan in 1992 also had some canon foreigners of it's own. Aside from the three main characters of the games at that time, it also featured Nikki as an ordinary version of Sonic, Nikki's family (Anita, Brenda and Paulie), Little John, Anton, Madd, [[CanonImmigrant Amy and Charmy]].
* Campion Bond of ''Comicbook/TheLeagueOfExtraordinaryGentlemen''. When every other character, no matter how background or minor, is taken from a work of Victorian literature, it is a shock to find a main character that's completely original, although an ancestor of Literature/JamesBond). Other Canon Foreigners are ancestors of other fictional characters, like the ancestor of [[Film/TheBigLebowski The Dude]] who makes a brief appearance in [[AllThereInTheManual The New Traveler's Almanac]]. More prominently, William Sampson, the League's cabbie, is the father of the Wolf of Kabul, from ''The Hotspur''.
* Originally the creators of ''Series/TheXFiles'' comics were told they could not use the character of the Cigarette Smoking Man so they created a mysterious blonde woman to fill his role. Later the producers changed their minds and the comics were allowed to use CSM and the mysterious blonde quietly vanished. It is unlikely she will ever appear in any other ''X-Files'' adaptation.
* The [[RecursiveAdaptation comic book tie-ins]] to ''WesternAnimation/BatmanTheAnimatedSeries'' had a few original villains who never appeared in the show, such as Mr. Nice and the Japanese assassin Kit Nozawa (though the former did eventually show up in a few issues of ''ComicBook/{{Robin|Series}}'').
* The comic books made to tie-in to ''WesternAnimation/JusticeLeague'' had a few as well, the most notable probably being the teen superheroine All-Star.
* The ''Franchise/StarTrek'' comics produced by DC in TheEighties featured a plethora of original characters, until Paramount exerted greater creative control over the series. This resulted in the cancellation of the first volume after issue 56, a new series launching after the debut of ''Film/StarTrekVTheFinalFrontier'', and the characters created by Mike W. Barr and his successors on the first series (including the final writer of the first series, Peter David), as well as the ''WesternAnimation/StarTrekTheAnimatedSeries'' characters, to be banned from use in the new series.
** Peter David attempted to add his own original characters, such as protocol officer R.J. Blaise, security officer Fouton, navigator Kathy Li, and a recurring villain, the Salla. Paramount (and [[ExecutiveMeddling Richard Arnold in particular]]) wasn't happy with anything taking focus away from the original cast, even though these characters existed primarily to play off of that cast (Blaise and the Salla for Kirk, Fouton for Chekov, and Li for Sulu), and Arnold ordered these characters removed by the end of the "Trial of James T. Kirk" arc. David, frustrated over his scripts getting rejected by Arnold, [[GettingCrapPastTheRadar submitted a particularly violent story]] under the pen name ''[[ComicBook/TheIncredibleHulk Robert Bruce Banner]]'', which ''was'' accepted. Concluding that his issues with Arnold had [[ItsPersonal become personal]], David quit the series following the "Return of the Worthy" arc, on which he collaborated with Bill Mumy; the "Banner" story would get published (under David's name) a few issues later. David did get to write a few more DC ''Star Trek'' issues (notably, the TNG portion of ''The Modala Imperative'', and a ''Star Trek'' Special that allowed him to give R.J. Blaise a proper send-off).
*** Peter David himself has managed to bring some of the first-series characters back in his ExpandedUniverse novels. ''WesternAnimation/StarTrekTheAnimatedSeries'' was, for a time, considered non-canon, but that did not stop David from integrating [[CatFolk M'Ress]] and Arex into crews in his ''Literature/StarTrekNewFrontier'' novels. The same series reintroduced comics-only character [[http://memory-beta.wikia.com/wiki/Nancy_Bryce Nancy Bryce]], who reflected upon her memory of fellow canon exile [[http://memory-beta.wikia.com/wiki/William_Bearclaw Bearclaw]]. The third member of their LowerDecks PowerTrio, Klingon refugee and acting ensign [[http://memory-beta.wikia.com/wiki/Konom Konom]], however, is likely exiled forever, given that ''Series/StarTrekTheNextGeneration'' established Worf as the first Klingon to become a Starfleet Officer.[[note]]Though it theoretically could be done if emphasis was placed on Konom's status as [[ExactWords a provisional officer who never went through the Academy]].[[/note]]
* As with ''Star Trek'', the ''Franchise/StarWars'' comics added dozens if not hundreds of new characters. Two of them -- Aayla Secura and Quinlan Voss (mentioned but not shown) -- actually make it CanonImmigrant status.
* In the late 1980s, Creator/DCComics did a ''Franchise/DocSavage'' series that centres around Doc being moved through time to the present day. The series included Doc's grandson and a team of new aides Doc assembled (as his original aides were now all old men). While interesting, these characters are unlikely to appear in any other version of the Franchise/DocSavage saga.
* In an odd bit of a RecursiveAdaptation, the official tie-in comic for the ''WesternAnimation/YoungJustice'' animated series added three more members to the Flying Graysons, the family of acrobats Dick Grayson belonged to before becoming ComicBook/{{Robin}}. While the Flying Grayson troupe from the comics consisted of Dick and his parents, the ''Young Justice'' comic introduced Richard, Karla and John Grayson, Dick's uncle, aunt and cousin respectively.
* ''Magazine/DisneyAdventures''
** The story of a one-shot comic taking place after the original ''WesternAnimation/ToyStory'' revolved around Speck, the puppy Andy got at the end of the movie. This was written years before ''WesternAnimation/ToyStory2'', which introduced his canon equivalent, Buster.
** In DA's ''WesternAnimation/DarkwingDuck'' comics, there was a popular recurring villain named Fluffy, a super-intelligent housecat with a [[PoweredArmor robotic suit of armor]], who never appeared in the official canon.
* The early ''Series/DoctorWho'' comics had John and Gillian, the Doctor's ''other'' grandchildren, and other, less well-remembered companions. ''Magazine/DoctorWhoMagazine'' comics had Sharon (companion to the Fourth Doctor), Sir Justin and Angus "Gus" Goodman (companions to the Fifth Doctor) Frobisher (long-running companion to the Sixth, and briefly, Seventh Doctors), Izzy, Fey, Kroton (a [[DefectorFromDecadence rogue Cyberman]]) and Destrii (companions to the Eighth Doctor) and the Tenth Doctor has Majenta Pryce. Other comics have featured other companions. The comic in ''Doctor Who Adventures'' has Heather [=McCrimmon=] and Wolfgang Ryter as companions to the Tenth Doctor.
** As well as companions, the DWM strip featured other recurring characters such as Max Edison and Colonel Muriel Frost. The latter ''might'' be a CanonImmigrant as "Major Frost" in "Aliens of London", in which case [[DeathByCameo she's dead]].
* In the early 90s, ''Magazine/NintendoPower'' published a series of comic adaptations of whatever game Nintendo was hyping during the year. They published ''Comicbook/SuperMarioAdventures'' (loosely based on ''VideoGame/SuperMarioWorld'') and ''VideoGame/TheLegendOfZeldaALinkToThePast'' in 1992, ''VideoGame/{{Star Fox|1}}'' in 1993, and ''VideoGame/SuperMetroid'' in 1994. Each comic took liberties with their source material by introducing new characters such as Floyd the salesman in ''Super Mario'', Roam the archer in ''Zelda'' (who is incidentally an {{expy}} of "[[NamesTheSame Jet Link]]" from ''Manga/{{Cyborg 009}}''), Fara Phoenix in ''Star Fox'', and Armstrong Houston in ''Super Metroid''.
* Marvel loved to do this in the 1980s with their adaptations from other media. They seemed to enjoy introducing relatives to certain characters; fathers, sons, and brothers, ESPECIALLY brothers! In ''WesternAnimation/DinoRiders'', Questar's brother pops up at the end of the 1st issue. In ''WesternAnimation/DefendersOfTheEarth'', The Phantom has to confront his evil brother.
* Various ''Franchise/{{Transformers}}'' comic lines have loads of this, introducing original Transformers, like Primus, Scrounge and Jhiaxus that never were in the toylines before. And with the... eagerness Transformers fans display, many of these characters reach CanonImmigrant status, earning their own toylines.
* The ''Franchise/MortalKombat'' comic by Malibu, in addition to featuring drastically different portrayals of canonical characters (the original Sub-Zero and Baraka were both good guys, while Kitana is romantically involved with Kung Lao instead of Liu Kang), also featured several characters exclusive to the books such as Hydro, a Lin-Kuei ally of Sub-Zero and the twins Sing and Sang. [[CListFodder Most of them were written so that the characters could use their Fatalities without killing any of the major characters from the games.]] Hydro later showed up in the ''WebVideo/MortalKombatLegacy'' web-series made to promote [[VideoGame/MortalKombat9 the Mortal Kombat reboot]].
* Ninja Turtles again: IDW's ComicBook/{{Teenage Mutant Ninja Turtles|IDW}} book, while focusing mostly on characters brought in from other TMNT incarnations, has also introduced a handful of new characters of its own, such as cat mutant Old Hob, who was mutated at the same time as the turtles; and Alopex, a mutant arctic fox.
* DC Comics' ''WesternAnimation/ThePowerpuffGirls'' book introduced the [[ThePsychoRangers Powerpunk Girls]], who are popular in fan fiction. This one is rather debatable, since they were meant to show up in the TV series. But due to over-blowing their budget, the creators weren't able to make the episode and gave it to DC for a [[MilestoneCelebration 50th issue anniversary special]].
* ''ComicBook/{{Shazam}}: The Monster Society of Evil'' (and its sequel series, ''ComicBook/BillyBatsonAndTheMagicOfShazam'') featured a blonde Comicbook/LoisLane {{Expy}} named Helen Fidelity, who was in a TwoPersonLoveTriangle with Captain Marvel, and who (to date) has never appeared in the main Fawcett and DC Comics continuities.
* Malibu Comic's ''[[ComicBook/MalibuComicsStreetFighter Street Fighter]]'' had Nida, a woman who blames Ryu for her father's death. If the comic had continued [[spoiler: it would have turned out to have been an [[EvilKnockoff evil clone]] created by M. Bison]].
* ''ComicBook/MyLittlePonyFriendshipIsMagicIDW'' is confirmed to feature several, one of whom will act as a villain.
* If Franchise/TheSmurfs comic books are considered the official canon (and they most likely are in Europe), then the American-produced [[WesternAnimation/TheSmurfs cartoon show]] and [[Film/TheSmurfs film series]] have characters that are considered foreigners to it, which also include the human allies of the Smurfs as well as the villains created by Hanna-Barbera and Sony Pictures. For the Smurf characters of all three continuities to be present together, they would have to appear in MerchandiseDriven stories such as the ''Smurfs Village'' game app for the Apple iPad and Android.
* The IDW series for {{Franchise/Transformers}} has introduced a few new characters to the G1 Continuity. ComicBook/TransformersAllHailMegatron introduced us to Drift and ComicBook/TransformersLastStandOfTheWreckers as well as ComicBook/TransformersMoreThanMeetsTheEye created Rung, Fulcrum, Atomizer, Ambulon, Pharma, Tyrest and the Decepticon Justice Division. ComicBook/TransformersCombinerWars came around and also introduced the Mistress of Flame, the Protectobot Rook and Off Road (a character who was originally meant to be Ruckus but made into his own individual).
* When Creator/JackKirby introduced the second generation of the Newsboy Legion (the [[GenerationXerox virtually identical sons]] of their [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] counterparts) in the pages of ''[[Comicbook/JimmyOlsen Superman's Pal Jimmy Olsen]],'' he added an extra member, the scuba diver Flippa Dippa -- who is [[TokenMinority black.]]
* Shinomura in the ''Film/{{Godzilla 2014}}'' tie-in comic ''Godzilla: Awakening'', much like the Mutos.
* ''ComicBook/GodzillaRulersOfEarth'' has the Devonians and the Cryog, two non-Toho related alien species while Trilopod will be the first non-Toho Kaiju.
* When Marvel had the license to publish Godzilla comics back in the 70's, they didn't have the rights to any of Toho's other monsters, so writer [[MoonKnight Doug Moench]] had to invent new antagonists for Godzilla (apart from also having him spar with Marvel's established super-heroes, naturally). These included the ape-man Yetrigar, the monster-making mad scientist Dr. Demonicus, the alien Megans, and the giant robot Red Ronin -- all of whom are still part of Marvel continuity and have reappeared sporadically over the years. Heck, the Megans even got their own ''action figure'' in the 1990's SilverSurfer cartoon tie-in line.
[[/folder]]

[[folder:Films -- Animation]]
* Lola Bunny in ''Film/SpaceJam'' would eventually become a WesternAnimation/LooneyTunes CanonImmigrant, with analogues in ''WesternAnimation/BabyLooneyTunes'', ''WesternAnimation/LoonaticsUnleashed'', and ''WesternAnimation/TheLooneyTunesShow''.
* Wybie in the ''WesternAnimation/{{Coraline}}'' [[TheFilmOfTheBook movie]], who serves as TheWatson.
* ''WesternAnimation/AstroBoy 2009'' has ''loads'' -- Zane, Widget, Grace, Sludge, and Orrin, to name the more appealing ones -- as well as replacing Cathy with Cora.
* The Doorknob in Disney's ''Disney/AliceInWonderland'' is the only character in the entire movie who was not originally created by Creator/LewisCarroll.
* The Night Fury dragons are actually found only in the [[WesternAnimation/HowToTrainYourDragon film adaptation]] of ''Literature/HowToTrainYourDragon''. In the books, Toothless was much smaller and looked more like a Terrible Terror dragon than a Night Fury dragon.
* Lucifer in ''Disney/{{Cinderella}}''. For that matter, a good number of animal sidekicks in Disney movies count.
** Averted with Djali, who is indeed in Victor Hugo's original novel.
* Thumper and Flower in ''Disney/{{Bambi}}''.
* Gopher in Disney's ''Franchise/WinnieThePooh'' cartoons. This gets lampshaded several times, the subtlest probably being:
--> "Here's my card! I'm not in the book, but I'm at your service!"
** So much so that "Not in the book" could very well have been the name of this trope.
* Andrea Beaumont, the [[spoiler: title villain]] from ''WesternAnimation/BatmanMaskOfThePhantasm''.
* Li Mei, the Mandarin's descendant from ''WesternAnimation/TheInvincibleIronMan''. Though a similar character named Sasha has been introduced in the comics as the Mandarin's daughter, it's unclear if the two are intended to be the same person.
* The 1991 film adaptation of ''Literature/TheLittleEngineThatCould'', we get Chip the bird (a friend of the title character), a doctor engine, a JerkAss control tower, and a human boy's skeptical older sister.
* Mika Milovana, princess of Dale in Gene Deitch's 1966 adaptation of ''The Hobbit''.
* Sunset Shimmer and Flash Sentry in ''WesternAnimation/MyLittlePonyEquestriaGirls'', and the Dazzlings in ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks''.

[[folder:Films -- Live-Action]]
* Franchise/{{Batman}}
** Rachel Dawes from ''Film/TheDarkKnightSaga''.
** ''Film/BatmanForever'' has a love interest that only existed in that movie.
** ''Batman Forever'' also gives [[ComicBook/{{Robin}} Dick Grayson]] a brother, who died along with the other Flying Graysons.
** Subverted in ''Film/TheDarkKnightRises'', which introduces two new characters: Miranda Tate and John Blake. [[spoiler: Miranda Tate is really Talia al Ghul, and John Blake is a {{composite|Character}} of the first three Comicbook/{{Robin}}s.]]
** Max Schrek of ''Film/BatmanReturns'' is notable as he's a canon foreigner that holds his own as a villain in a BigBadEnsemble alongside Penguin and Catwoman.
** While Vicki Vale from ''Film/{{Batman}}'' had a history in the comics going decades back, her sidekick Alexander Knox was created expressly for the film.
* Ross Webster and Gus Gorman from ''Film/SupermanIII''. Also ComicBook/LexLuthor's TotallyRadical nephew Lenny Luthor in ''Film/SupermanIVTheQuestForPeace''.
* ''Film/TheLordOfTheRings'' trilogy added various tertiary characters as well as additional individually identified bad guys. To this end, one of the Uruk-Hai in ''Fellowship of the Ring'' was given more importance and called "Lurtz". Similarly, Gothmog fills this role in ''Return of the King''. Technically, the latter was in the book, but only mentioned in passing, and it's unspecific whether he's even an orc. The movie [[AdaptationExpansion expands on this]] by making him a big nasty orc [[GrotesqueGallery with what appears to be Proteus Syndrome]].
* Sharku, the nastily injured Orc Warg-rider in ''The Lord of the Rings: The Two Towers''. The name is from one of Saruman's nicknames during the Scouring of the Shire in ''The Return of the King''. Sharku also appears in the game ''The Lord of the Rings: The Battle for Middle-earth II''.
* ''Film/TheHobbit'' trilogy has the character Tauriel; a female Wood-Elf played by Evangeline Lilly, put in to make sure the film has [[AffirmativeActionGirl at least one female character]].
* ''Film/MortalKombat'' has Liu Kang's younger brother Chan, and Art Lean, an Earthrealm martial artist who befriends Johnny Cage [[spoiler: before being killed by Goro]].
* Yet another ''Film/TeenageMutantNinjaTurtles'' example; as in the original cartoon, they outnumber the actual canon characters. Tatsu, (TMNT I and II), Tokka, Rahzar (TMNT II), all the introduced characters in TMNT III and Max Winters (WesternAnimation/{{TMNT}}) are the most notable.
* The ''Manga/DeathNote'' movies added a female police officer named Sanami as an AffirmativeActionGirl. There's also Light's girlfriend from the first movie.
* ''Film/HarryPotter'':
** The talking {{Shrunken Head}}s in the Knight Bus scene from ''Prisoner of Azkaban''.
** The train station diner waitress in ''Half-Blood Prince''.
** Nigel is this... sort of. He's a CompositeCharacter for the Creevey brothers, but he's still original to the films. Okay, he's Dennis Creevey, but at least the name is original.
* The Owl in Creator/IrwinAllen's 1985 ''Literature/AliceInWonderland'' is a character that does not appear in the original Lewis Carroll novel.
* Tom Sawyer and Dorian Gray in ''Film/TheLeagueOfExtraordinaryGentlemen''. Although those characters were alluded to in the original material, they were never seen and certainly were not main characters. The film also features an Expy for the Invisible Man because they couldn't get the rights to the Creator/HGWells character.
* Alice in the ''Film/ResidentEvil'' films, [[SpotlightStealingSquad to the point of overshadowing the canon characters]].
* Calibos and Bubo in the original ''Film/ClashOfTheTitans'', and Io in the remake.
* Agent Myers was added to ''Film/{{Hellboy}}'' as an AudienceSurrogate. The sequel [[PutOnABus ditches him]], since his role is no longer necessary.
* ''Film/{{Clue}}'' had Wadsworth the butler. [[spoiler:Wadsworth can also be considered a result of ThirdOptionAdaptation; that way, at least one of the endings - the last to be shown on editions that show all three in sequence, implying its canonicity - would have a culprit who wasn't one of the playable characters.]]
* Robert Hammond, a U.S. Senator and the father of Hector Hammond, in ''Film/GreenLantern''.
* In ''Film/{{Supergirl}}'', all of the major characters save Supergirl herself, her parents, Comicbook/JimmyOlsen, and Lucy Lane. Another (sort of) exception is Principal Danver. In the comic book, the Danvers are Supergirl's foster parents on Earth. Perhaps this character (or one of his relatives) was supposed to adopt Supergirl in a sequel that was never made.
* The ''Film/BladeTrilogy'' movies have many:
** In [[Film/{{Blade}} the first one]], Blade and Deacon Frost were the only comic characters. Blade's quasi-love interest and all of the named vampires were created for the movie.
** In [[Film/BladeII the second]], Blade was essentially the only comic character to be featured in the movie. While there was a team called the ''Blood Pack'' in the original material, the individual members featured in the movie were new.
** Like the Blood Pack, [[Film/BladeTrinity the third film]] featured a team of vampire hunters that were lifted from the comics called ''Night Stalkers'', but Hannibal King was the only member taken from the comic series. Whistler did not have a superhero daughter and the rest were completely new characters. Also, while Creator/MarvelComics did have a version of {{Dracula}} who has fought Blade many times, this film featured a version that was taken in a different direction.
* Aunt Millicent in [[Film/PeterPan the 2003 version]] of ''Literature/PeterPan''.
* Count Olga, TheDragon, in ''Film/SnowWhiteAndTheThreeStooges'' is this to the Snow White tales, mainly so PrinceCharming will have a villain to fight in the climax.
* '''Everybody''' who isn't ComicStrip/DickTracy in the 1937 ''Dick Tracy'' serial, up to and including giving Tracy a brother who has never appeared in the comic strips, "Gordon Tracy".
** Although the comic strip's current creative team has now [[CanonImmigrant officially incorporated]] the [[DeathByOriginStory late]] Gordon into Dick Tracy's [[RetCanon backstory.]] The villains from ''Dick Tracy Vs. Cueball'' and ''Dick Tracy Meets Gruesome'' also now have CanonImmigrant status.
* Franchise/MarvelCinematicUniverse.
** [[Characters/AgentsOfShieldTeamCoulson Agent Phil Coulson]]. [[EnsembleDarkhorse/{{Film}} Thanks to his popularity]], [[CanonImmigrant he was imported into the comics]] as a buddy of [[AffirmativeActionLegacy the second Nick Fury]].
** ''Film/{{Thor}}'' has Doctor Selvig and Jane's buddy Darcy.
** ''Film/TheAvengers'' has the Other, an alien working for [[spoiler: Comicbook/{{Thanos}}]].
** While the [[Film/CaptainAmericaTheFirstAvenger Strategic Scientific Reserve]] is made up of established comic characters and is one of the MCU's in-universe predecessors to S.H.I.E.L.D., the organization itself fits this trope, as it was created solely for the movie.
** Harley [[spoiler: and Trevor Slattery]] from ''Film/IronMan3''.
** In a PosthumousCharacter example, ''Film/CaptainAmericaTheWinterSoldier'' establishes that TheFalcon had a close friend named Riley who was killed in action during TheWarOnTerror.
* ''Film/TheMagicChristian'', based on a novel about a billionaire named Sir Guy Grand, creates the secondary lead character of Grand's adopted son so that Music/RingoStarr can star alongside Creator/PeterSellers.
* Captain Sawada in ''Film/StreetFighter''.
* The Transylvanians from''Film/TheRockyHorrorPictureShow''. The original stage version used "phantom" back-up singers who weren't part of the story, not party-goers.
* Colonel Hardy and General Swanwick don't exist in the comics ''Film/ManOfSteel'' is based on. Though Swanwick might be considered a stand-in for Lois Lane's father General Sam Lane, who filled the military brass role in ''ComicBook/SupermanSecretOrigin''. In addition Colonel Hardy is referred to by the codename "Guardian" near the end of the movie. Colonel Hardy is seemingly a replacement for Jim Harper, aka Guardian.
* ''Film/{{Godzilla 2014}}'':
** Although Creator/{{Toho}}'s ''Franchise/{{Godzilla}}'' franchise features plenty of giant mutant insectoid monsters, the makers of this film decided to introduce the Mutos as an original set of this sort of creature for Godzilla to fight.
** The Teaser Trailer Monster only appeared in the SDCC teaser trailer, but did not appear in the final film. There is, however, a small nod to it in the form of a peculiar and brightly coloured millipede in the Janjira zone.
* Millicent and her [[spoiler: explorer father]] in ''Film/{{Paddington}}'', who never appeared in any of [[Literature/PaddingtonBear the books]] is brought in to make an action/thriller plot.
[[/folder]]

[[folder:Literature]]
* Although, like the comics, the Franchise/StarTrekExpandedUniverse novels seldom used original recurring characters in the late '80s-early '90s, it was the norm by the late '90s and the modern novels make regular use of Canon Foreigner characters, and there are whole book ''series'' that aren't based on the shows and are populated mostly by Canon Foreigners or AscendedExtra characters (e.g. ''[[Literature/StarTrekTitan Titan]]'', ''[[StarTrekVanguard Vanguard]]'', ''[[Literature/StarfleetCorpsOfEngineers Corps of Engineers]]'', ''Literature/IKSGorkon'', and ''[[Literature/StarTrekDepartmentOfTemporalInvestigations Department of Temporal Investigations]]''). In spite of their popularity and critical importance in the ExpandedUniverse, neither [[Literature/StarTrekNewFrontier Captain Calhoun]] nor [[Literature/StarTrekDeepSpaceNineRelaunch Elias]] [[Literature/StarTrekTheLostEra Vaughn]] has ever been featured in canonical ''Franchise/StarTrek''. Although one major character created for the ''Series/StarTrekDeepSpaceNine'' novels set after the series was intentionally based on a certain extra who was only seen from the back in a canon episode.
* Virgin Publishing's Literature/DoctorWhoNewAdventures novels created a number of new companions for the Seventh Doctor, including Franchise/BerniceSummerfield, Roz Forrester and Chris Cwej. Virgin's Literature/DoctorWhoMissingAdventures had Grant Markham, a short-lived companion to the Sixth Doctor. BBC Books' Literature/EighthDoctorAdventures range had Samantha Jones, Fitz Kreiner, Compassion, Anji Kapoor, and Trix [=MacMillan=]. Innumerable new villains have occurred in the Franchise/DoctorWhoExpandedUniverse. One, Literature/FactionParadox, the EvilCounterpart to the Time Lords, spun off into its own sub-universe of audio plays, comics and novels. They began in novels.
* Hotblack Desiato and Disaster Area in ''Literature/TheRestaurantAtTheEndOfTheUniverse'' and subsequently the TV version of ''Series/TheHitchhikersGuideToTheGalaxy'' were created to replace the sequence with the Haggunenons in the radio series, which was mostly written by John Lloyd, and therefore Creator/DouglasAdams didn't feel was "his".
* The first ''Franchise/StarCraft'' ExpandedUniverse novel, ''Liberty's Crusade'', was a PragmaticAdaptation of the first game's Terran campaign. Its viewpoint character is a journalist named Michael Liberty who is embedded with then-Colonel Edmund Duke's Alpha Squadron (partly to hide him from Confederate magnates he pissed off with his previous story). With the exception of ''Queen of Blades'' (which covers the ''SC'' Zerg campaign from Jim Raynor's viewpoint) and ''Speed of Darkness'' (which focuses on a group of Confederate Marines on Mar Sara who were [[HeroOfAnotherStory Heroes of Another Story]] to the PlayerCharacter of the Terran campaign[[note]]They fought a [[YouShallNotPass holding]] [[LastStand action]] against the Zerg at the same time as the third Terran mission, which diverted substantial forces away from the PC's troops and enabled their escape.[[/note]]), the other books don't touch the game campaigns, inevitably creating dozens of Canon Foreigners.
* Inevitable in the Franchise/StarWarsExpandedUniverse, since its timeline spans roughly 100,000 years of which the movies comprise about forty.
* ''Franchise/SonicTheHedgehog''
** Stevie, Eggor, and Casear from ''Literature/SonicTheHedgehogInRobotniksLaboratory''.
** Likewise Carrie the Copyu, Eric the Echidna and The Organizers from ''Literature/SonicTheHedgehogInTheFourthDimension''
** Ichneumon (Iggy) the White Mouse from ''Literature/SonicTheHedgehogAndTheSiliconWarriors''
* ''LightNovel/AnotherNote'' expands on the LABB Murder case mentioned briefly in ''Manga/DeathNote'', and introduces L's EvilTwin, Beyond Birthday.
[[/folder]]

[[folder:Live Action TV]]
* Girl turtle, Venus de Milo from ''Series/NinjaTurtlesTheNextMutation''. A CanonImmigrant, sadly [[CanonDisContinuity she's not]]. Also the Dragon Emperor, Dr. Quease, and Vam Mi.
* Gaius of ''Series/{{Merlin}}'', who plays the mentor role now that Merlin himself is a teenager. Apparently they didn't feel like using Blaise, who was Merlin's actual mentor in the original myth.
* ''Series/{{Smallville}}''
** [[spoiler: Lex Luthor's sister]] Tess Mercer, who was a CompositeCharacter of Eve Teschmacher and Mercy Graves, Luthor's female accomplices from ''Film/{{Superman}}'' and ''WesternAnimation/SupermanTheAnimatedSeries'' respectively. The final episode also revealed that she had a bit of [[spoiler: Lena Luthor]] thrown in as well.
** Clark's friend and sidekick Chloe Sullivan. {{Lampshade|Hanging}}d when the Comicbook/{{Legion of Super-Heroes}} visit and have knowledge of all of Clark's canon friends but none of her.
* ''Franchise/ArrowVerse'':
** Tommy Merlyn and John Diggle in ''Series/{{Arrow}}'', though both have since become {{Canon Immigrant}}s in the Comicbook/{{New 52}}.
** Its SpinOff ''Series/TheFlash2014'' gave the founder of S.T.A.R. Labs a wife (Tess Morgan).
* Pretty much everyone in ''Series/AgentsOfSHIELD'' except for Coulson (who is a CanonImmigrant) and Victoria Hand. Even the [[MonsterOfTheWeek Freak Of The Week]] villains tend to be mostly new characters. In fact, one of the most frequent criticisms of the show is that it's marketed as a Creator/MarvelComics show, despite mostly using original characters.
** Melinda May, Skye, and the others are now officially {{Canon Immigrant}}s thanks to the ''S.H.I.E.L.D.'' series Marvel is putting out.
** The show has also moved away from the heavy use of Canon Foreigners in response to the criticism from fans. Characters like Deathlok and Blizzard debuted in the latter half of Season 1, while other comic characters like Comicbook/{{Mockingbird}} and Absorbing Man have been confirmed or Season 2.
** Subverted with Skye, who -- after a season's worth of being this -- turned out to be the cinematic universe's version of [[spoiler: Daisy Johnson, aka Quake.]]
* ''AgentCarter'' has several, such as SSR agents Daniel Sousa, Jack Thompson and Ray Krzeminski, along with waitress and friend of Peggy's, Angie Martinelli. The most prominent addition is Dottie Underwood, [[spoiler:a villainous assassin who was trained by the Black Widow program. While she shares similarities to comic-based Black Widows such as [[ComicBook/BlackWidow Natalia Romanova]] and Yelena Belova, Dottie herself was created specifically for the show.]]
* Jack [=McGee=] from ''Series/TheIncredibleHulk''. A really prominent example in that he's a canon foreigner who has been worked into [[YouWouldntLikeMeWhenImAngry a very well known catch phrase]].
* Kivaara, a tiny Kivat for the world of ''Series/KamenRiderKiva'' and Kamen Rider Abyss, a shark-themed Rider for ''Series/KamenRiderRyuki'', both appear for the first time in the series' CrisisCrossover, ''[[Series/KamenRiderDecade Decade]]''.
** A lot of the films introduce new characters (and sometimes even [[SixthRanger new Riders]]) who never appear in the TV shows proper. A few of them like [[Series/KamenRiderDouble Kamen Rider Skull]] and [[Series/KamenRiderFourze Kamen Rider Nadeshiko]] have at least managed to appear in more than one movie.
* How much you consider ''Franchise/PowerRangers'' an adaptation of ''Franchise/SuperSentai'' is variable (depending on the season. You get some that are all their own and just borrow some fight footage, and some that are shot-for-shot remakes.) but in addition to non-sentai supporting casts, ''Series/PowerRangersLightspeedRescue'' has the Titanium Ranger, a SixthRanger that doesn't exist in any form in the original series, which it is otherwise quite similar to. The Spirit Rangers may or may not count (the characters existed; that storyline and their getting shiny suits didn't.)
** Lord Zedd, the BigBad of ''Series/MightyMorphinPowerRangers'' Season 2, had no counterpart in the Japanese ''Series/KyoryuSentaiZyuranger''.
** The Shogun Ultrazord from Season 3 of MMPR is an interesting case. The two Zords that combined to create it ''did'' originate in the Super Sentai source material, but were from two separate shows. The Shogun Megafalconzord was originally Super Muteki Shogun from ''Series/NinjaSentaiKakuranger'', while Titanus was Beast Knight God King Brachion from the aforementioned ''Zyuranger''. As no footage of the Shogun Ultrazord existed in any of the Japanese originals, the producers were forced to use [[OffTheShelfFX the toy itself]] in the show!
** ''Series/PowerRangersRPM'' has an attack with the wheels of the suits that didn't appear in Go-onger.
*** It became {{RetCanon}} in ''Series/KaizokuSentaiGokaiger''.
** The A-Squad, the [[ThePsychoRangers team of evil Rangers]] from ''Series/PowerRangersSPD'', were created exclusively for the American adaptation.
** Back when ''NinpuuSentaiHurricaneger'' was going to be adapted as ''Power Rangers Hexagon'' instead of ''PowerRangersNinjaStorm'', there were plans for a third Gouraiger ("Thunder Rangers" in the U.S. version), who would have been a teenage girl with a Dark Yellow color scheme. This never happened, but oddly enough, a CanonForeigner Gouraiger ''was'' later introduced introduced in ''HikoninSentaiAkibaranger'', and she was both yellow and a girl to boot!
* ''Series/PrettyGuardianSailorMoon'' has the GodCreatedCanonForeigner "Sailor Luna", who is a visual reference to Luna's human form from the manga and a ChibiUsa {{Expy}}. There's also Princess Sailor Moon, who is believed by fans to be a GodCreatedCanonForeigner due to Takeuchi-sensei's artwork of her.
** The show also introduced "Mio Kuroki", a mysterious and malicious teenager who enjoyed making the senshi's lives miserable. While described as a "shadow" of Beryl (who could more directly interact with the cast), she seemed to have a degree of free will.
* Cameron Phillips and Derek Reese from ''Series/TheSarahConnorChronicles'' don't exist as far as the ''Franchise/{{Terminator}}'' movies are concerned.
* Insofar as we can call hundreds of years of legend "canon", the 1980s series ''Series/RobinOfSherwood'' introduced the idea of including a Saracen to Robin Hood's outlaws, a figure that was popular enough to be included in Kevin Costner's ''Prince of Thieves'' and again the BBC's 2006 ''Series/RobinHood''. The latter television series also introduced original characters Isabella (Guy of Gisborne's sister) and Kate (Locksley village girl) as {{Affirmative Action Girl}}s after Marian and Djaq (who ironically, was the Saracen) were written out.
* Series/{{Xena|Warrior Princess}} functions as something of a Canon Foreigner to Myth/ClassicalMythology. Her story takes place as the same time as ''Series/HerculesTheLegendaryJourneys'', and featured the same Greek Gods, placing her squarely in the same area as the actual mythical Hercules.
* ''Series/GameOfThrones''
** Ros, who serves equally well as MsFanservice and TheWatson, for especially thorny bits of exposition, and additionally fills the (relatively minor) roles of Kyra and Alayaya in the books. George RR Martin has said he intends to give her a cameo in a later book, so she may soon get promoted to CanonImmigrant.
** Alton Lannister
** Kovarro, one of Daenerys's bloodriders. He has elements from Dany's other bloodriders, favoring the arakh like the book version of Rakharo. There is an also an older bloodrider named Malakho who is seen amongst other Dothraki.
** The Spice King from Qarth. There is an Ancient Guild of Spicers in Qarth, but no prominent members directly interact with Dany.
** Olly, who is a rather blatant chekov's gun if you've read the books. A lot of book readers hate him.
* Jake from ''Series/TheSecretCircle'' didn't exist in the books.
* A lot of characters in ''Series/TheWalkingDead'', a large amount of characters from the show never appeared in the comics including Daryl Dixon, Merle Dixon, Beth Greene, Leon Basset, Gary Taylor, Patty Taylor, Jacqui, Morales, Dr. Jenner, Guillermo, Jimmy, Dave, Tony, Randall, Nate, Sean, Oscar, Big Tiny, Rowan, Haley, Tim, Shupert, Crowley, Gargulio, Karen, Noah, The Grady Memorial Hospital police officers and Spencer Monroe.
* ''Series/TheVampireDiaries'' has a few, mostly family members of canon characters. Alaric is a good example, and Jeremy qualifies as well -- he's too far different, and fills such a completely different role in the story, from Elena's younger sister in the books that he can't be considered the TV version of her.
* ''Series/TrueBlood'' almost exclusively uses characters based in some way off characters from the books, with the prominent exception of Jessica Hamby, Bill's vampire progeny.
* Fish Mooney on ''Series/{{Gotham}}'' is a created-for-TV character, as is her [[TheDragon dragon]] Butch Gilzean. A number of the show's criminals are new, in fact, so that Franchise/{{Batman}}'s entire RoguesGallery won't get a 15 year head start on him.
* ''Series/{{Supergirl 2015}}'': Kara has a foster sister, Alex Danvers, on the show, whereas in the comics the Danvers never had any biological children.
* ''Series/{{Sherlock}}'': Molly Hooper. In the books, Sherlock did a lot of the crazy experiments and whatnot. Also, aside from John, no one really appreciated him.

[[/folder]]

[[folder:Pinball]]
* The iconic gumball machine in ''Pinball/TheTwilightZone'' was not taken from an existing episode of the series.
* The most prominent toy in Creator/SternPinball's ''[[Pinball/BatmanStern Batman]]'' game (based on ''Film/TheDarkKnight'') is a large yellow construction crane that swings out over the playfield -- and is nowhere to be found in the movie.
[[/folder]]

[[folder:Radio]]
* ''Radio/TheAdventuresOfSuperman'' introduced Jimmy Olsen, Inspector Henderson, Kryptonite and the names "Daily Planet" and "Perry White."
* Creator/TheBBC Radio 4 series ''The Rivals'' adds Inspector Lestrade from the ''Literature/SherlockHolmes'' books to the adventures of various other Victorian detectives, creating a sort of SharedUniverse from unrelated stories.
* Nathaniel Ward of the H. P. Lovecraft Historical Society's projects is an unusual case. Originally created as a ''Call of Cthulhu'' RPG character, the hosts of the [[http://www.cthulhulives.org/radio/DART/index.html Dark Adventure Radio Theatre]] series later spoke of him as the hero of a separate program within the audio adaptations' own miniature universe. Eventually, Ward featured in the HPLHS's film adaptation of ''Film/TheWhispererInDarkness'', [[http://www.cthulhulives.org/store/storeDetailPages/codex.html a monograph]], and two of the Society's other radio dramas to date (''The Dreams in the Witch House'' and ''Imprisoned with the Pharaohs''). He's implied to have an epic life beyond even the aforementioned titles.
* While the characters of the software are guests for ''Radio/NewDynamicEnglish'', there are also new characters being interviewed. There's also Elizabeth Moore, who's the host of ''Functioning in Business'', and can be heard socializing with Max and Kathy in the Story Interludes.
[[/folder]]

[[folder:Tabletop Games]]
* Whenever ''TabletopGame/{{Clue}}'' comes out with an expanded version or spinoff based around Boddy Mansion (as opposed to say, ''Franchise/StarWars'' or ''WesternAnimation/TheSimpsons'') it seems traditional to add a bottle of poison as a weapon, as well as the appearances of Madam Rose, Sgt. Grey, M. Brunette, and Miss Peach as extra characters.
* The mage/planeswalker Jodah in ''TabletopGame/MagicTheGathering'' was created by Jeff Grub for the novelizations of the plot of ''The Dark'' and the ''Ice Age'' cycle of books, created in 1999 (where the sets were created in 1994-5). He'd prove popular enough to get an Avenger card in ''Planar Chaos''.
* The ''Anime/NeonGenesisEvangelion'' RPG game ''The NERV White Paper'' introduced Maria Vincennes, a female EVA pilot from America.
[[/folder]]

[[folder:Theatre]]
* ''Theatre/TheMostHappyFella'', adapted from the straight play ''Theatre/TheyKnewWhatTheyWanted'', built the comic BetaCouple of Cleo and Herman out of whole cloth, and gave Tony a sister Marie to object to his marriage. (In the original play, the objector is the Catholic padre; also, Amy jokingly refers to herself at one point as 'Cleo', playing off Antony and Cleopatra.)
* Several characters in ''Theatre/AsYouLikeIt'' (which was Shakespeare's adaptation of the Thomas Lodge novel ''Rosalynde''), most importantly [[TheJester Touchstone]] and Jacques (of "All the world's a stage" fame). The rest of the Canon Foreigners in the story are all related to them in some way: Jacques, being a [[TheCynic cynical]] [[ThePhilosopher philosopher]], gets a scene where he [[SlidingScaleOfIdealismVersusCynicism plays off]] the idealistic, music-loving "Amiens", while Touchstone's subplot necessitates the inclusion of his love interest, "Audrey, a country wench", a country priest named "Oliver Mar-Text", and "William", Audrey's ex-boyfriend.
* Swiss Miss from ''Theatre/SpiderManTurnOffTheDark''. Within the actual story, [[LeaningOnTheFourthWall it's more or less acknowledged]] that [[AffirmativeActionGirl she was created to add a female villain to Spider-Man's otherwise male rogue's gallery]].
* A lot of characters in the ''Theatre/SeraMyu'' musicals. Sailor Astarte, Space Knight, Lemures Baba, a whole bunch of new Shadow Galactica members...it'd take too long to name every new character introduced.
[[/folder]]

[[folder:Toys]]
* Creator/{{Kenner}}'s ''Super Powers Collection'' contained a few characters not seen in either Franchise/TheDCU or the ''WesternAnimation/SuperFriends'' TV series. Among the new characters were heroes named [[http://www.actionfigureinsider.com/archives/sp/goldenpharoah.html Golden Pharaoh]], [[http://www.actionfigureinsider.com/archives/sp/cyclotron.html Cyclotron]], and [[http://superfriends.wikia.com/wiki/Silicon Silicon]].
* The Pink Shogunzord from ''Series/MightyMorphinPowerRangers'' only exists in the toy line, as ''Series/NinjaSentaiKakuranger'', the show Season 3 of MMPR was adapted from, did not feature a Pink Ranger.
* The toy line for ''Series/PowerRangersInSpace'' contained a Zord named Silver Titanus, who appeared in neither the show itself, nor ''Series/DenjiSentaiMegaranger'', the Japanese series it was adapted from.
* As mentioned in the Live-Action TV section, the Titanium Ranger from ''Series/PowerRangersLightspeedRescue'' did not exist in ''Series/RescueSentaiGoGoFive''. Adding to that, the Titanium Ranger had a toy-exclusive Zord called the Titanium Land Crawler, which did not appear in either TV show.
* The toy line for ''Series/PowerRangersRPM'' included the Mammoth Ranger, the T-Rex Ranger, and the Triceratops Ranger. None of these characters ever appeared in the show, but the Paleozords they were modeled after ''did''.
* The ''Series/PowerRangersDinoCharge'' toyline included an ammonite zord. While there was an ammonite charger in the series, it was only a power-up and never had an associated ranger or zord in neither the adapted nor [[Series/ZyudenSentaiKyoryuger original]] series.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/StarWarsGalaxies'' introduced the Force Sensitive Village of Aurilia, Vader's failed apprentice Mellichae, The Meatlumps and their King to name a few. These canonical additions, among many others, have been cited in other ''Star Wars'' mediums.
* Another ''Star Wars'' canon foreigner, [[VideoGame/DarkForcesSaga Kyle Katarn]] is perhaps one of the most prominent video game-based canon additions from the Jedi Knight series who has spawned his own books and action figures.
* ''VideoGame/TheForceUnleashed'' lets you ''play as'' a canon foreigner!
* The original characters in the ''VideoGame/StreetFighterEX'' series are owned by Arika, the company that developed the game, instead of Capcom. When the developers realized this, they retconned the backstories for Doctrine Dark, Pullum Purna, and Garuda to distance them from the canon ''Franchise/StreetFighter'' cast (for example, Garuda, who was originally a demon created by the Satsui no Hadou, was now a manifestation of evil energy). Blair Dame and Allen Snider were also put in a non-Capcom related fighting game called ''VideoGame/FightingLayer''.
** There's also Captain Sawada from both versions of the ''[[Film/StreetFighter Street Fighter: The Movie]]'' [[RecursiveAdaptation game]], as well as Blade and his {{palette swap}}s from the arcade version.
* Apple in the ''Anime/SaberMarionetteJ'' game (Japan-only).
* Joey La Rocca, Big Pussy Bonpensiero's illegitimate son in ''Series/TheSopranos Road to Respect''
* Cyber Spider from the ''Bucky O'Hare'' arcade game.
* The ''Franchise/TeenageMutantNinjaTurtles'' video games by Creator/{{Konami}} managed to avoid this for most parts, but there have been a few exceptions:
** Aska from the SNES version of ''[[VideoGame/TeenageMutantNinjaTurtlesTournamentFighters Tournament Fighters]]''. She was created to fill in the gap as [[TheChick token chick]], since the other females in the game were the final boss Karai and DamselInDistress April O'Neil (though she did fight in the Genesis version). However, early builds of the game shows that her name was originally going to be "Mitsu", who was the heroine in ''Film/TeenageMutantNinjaTurtlesIII''.
** Sisyphus the mutant beetle from the Genesis version of ''Tournament Fighters'' was never in any other ''TMNT'' media, although its easy to think otherwise due to the number of anthropomorphic characters that were introduced to the toyline in later years.
** Tora and Shogun Warrior from the NES port of ''VideoGame/TeenageMutantNinjaTurtlesTheArcadeGame'' added to serve as bosses to the two NES-exclusive [[AdaptationExpansion extra stages]].
* The various third-party ''VideoGame/MegaManClassic'' productions add characters that would never be seen again -- all of the bosses from the PC games (.EXE renamings and coincidentally same-named bosses in later games notwithstanding), several characters from [[WesternAnimation/MegaMan the Ruby-Spears cartoon]], Akane and Yuuta from the OVA, Dreamwave's three "boss characters", etc.
** Creator/ArchieComics's [[ComicBook/MegaMan version]] includes the likes of Agent Roslyn Krantz, Dr. Lalinde, and Quake Woman.
* ''Franchise/{{Castlevania}}'': The character from ''Wai Wai World'''s Castlevania stage is [[http://castlevania.wikia.com/wiki/Simon_Belmont_III Simon Belmont III]], descendant of Simon Belmont, according to descriptions in two ''Wai Wai World'' guidebooks.
* ''VideoGame/CastlevaniaBloodlines'' has John Morris, son of Quincy Morris from Bram Stoker's ''{{Literature/Dracula}}'', and John's son Jonathan Morris in ''VideoGame/CastlevaniaPortraitOfRuin'', suggesting the events of the novel take place in ''Castlevania'''s timeline. John's 1895 birth date is a little late to fit well with the novel's ending unless events in this timeline happened differently.
* The [[ManipulativeBastard insidious]] House Ordos from the ''Franchise/{{Dune}}'' RTS games by Westwood Studios.
* Turned on its head in ''VideoGame/TheKingOfFighters 2002 Unlimited Match'': the new character Nameless was created specifically to take the place of K9999 from ''KOF 2001'', who was such a blatant [[CaptainErsatz ripoff]] of [[Manga/{{Akira}} Tetsuo Shima]] that SNK Playmore had trouble using him in later games.
** ''The King of Fighters EX'' and ''Maximum Impact'' sub-series, both falling squarely under AlternateContinuity, feature their own original faces, more than a few of whom could feasibly be inserted into the main canon with little (if any) alterations to their backstory. One example is Xiao Lon, the half-sister of Hizoku assassin Duo Lon, who was created with the intention of loosely linking together the original titles and the ''MI'' series while avoiding plot holes (her debut in ''Maximum Impact: Regulation A'', an UpdatedRerelease of ''[=MI2=]'', also featured Ash Crimson, a former teammate of Duo Lon's from the current "Tales of Ash" arc).
* Reika Kirishima, one of the playable characters in ''VideoGame/CastleOfShikigami III'', was originally the star of her own Laserdisc and Sega CD game called ''VideoGame/TimeGal''. She was also a playable character in ''Elevator Action Deluxe''.
* Mew Ringo from the PlayStation ''Manga/TokyoMewMew'' game.
* Wolfduck was a villain that only appeared in the ''WesternAnimation/DarkwingDuck'' video game.
* The ''Franchise/MetalGear'' canon excludes all the original characters from ''VideoGame/MetalGearGhostBabel'' and the ''VideoGame/MetalGearAcid'' games. If you wish to go further, there's also Twin Shot, one of the replacement bosses from the NES version of the original ''VideoGame/MetalGear'', as well as John Turner and Nick Myer, Snake's FOXHOUND comrades from ''VideoGame/SnakesRevenge'' (as well as the "Metal Gear 2" mecha from the same game).
** Teliko and Venus from the ''VideoGame/MetalGearAcid'' games did, however, make cameo appearances as playable characters in the canon game ''VideoGame/MetalGearSolidPortableOps''. In that game, they were described by the other characters as 'aliens'.
** Definitely Vermon [=CaTaffy=] and Higharolla Kockamamie from the NES ''Metal Gear'' games. Although neither character actually existed to begin with.
* One of the more extreme examples would be Nicole-458 from ''VideoGame/DeadOrAlive 4'', who doesn't appear in ''any'' work from the ''Franchise/{{Halo}}'' universe she comes from. She's supposed to be a member of the ''second'' class of Spartan-[=IIs=], which happens to be one of the few remaining elements from ''ARG/ILoveBees'' that neither Bungie nor 343i seem to have yet truly adopted as canon.
* In ''VideoGame/BatmanArkhamAsylum'', Batman meets in the titular asylum canon foreigners Frank Boles, Doctor Young, and Quincy Sharp. [[spoiler:As canon foreigners, they are allowed to be killed, as Boles and Young found out when they stopped being useful to the Joker...]]
* ''VideoGame/ScarfaceTheWorldIsYours'' has Felix and The Sandman.
* ''Film/TheGodfather: [[VideoGame/TheGodfather The Game]]'' has such characters as Monk and Frances Malone, "Jaggy" Jovino and The Trojan. [[spoiler: It doesn't end well for most of them.]]
* The Oppositio Senshi in ''VideoGame/SailorMoonAnotherStory''. Evil counterparts to the Inner Senshi and Moon.
* [[HeroicMime Ezekiel Holloway]] and [[BigBad Atticus Thorn]] in ''Franchise/TheHauntedMansion'' game.
* ''VideoGame/SpiderManShatteredDimensions'' has a few, mostly in the form of the Hammerhead from the Noir universe, (the developers said that he felt like a perfect fit and he ''did'' fit quite well), 2099 Hobgoblin, and [[spoiler: a female Dr. Octopus from 2099]]. There's also the DS versions, which have Noir Calypso and 2099 Silvermane.
* ''VideoGame/XMenDestiny'' revolves around three teenage mutants created exclusively for the game: Aimi Yoshida, Adrian Luca, and Grant Alexander. Aimi is the daughter of Sunfire, who ''is'' an actual character in the ''Comicbook/XMen'' and ''Comicbook/UncannyAvengers'' books.
* Mana Kirishima of the ''Anime/NeonGenesisEvangelion'' game ''Girlfriend of Steel''. A ThirdOptionLoveInterest introduced to shake up the existing Shinji/Asuka/Rei LoveTriangle, Mana was a CaptainErsatz mish-mash of the two existing girls -- Rei's gentleness mixed with Asuka's extroversion. She has maintained [[EnsembleDarkhorse good popularity with the fandom since]], to the point she became part of the cast of the AU manga ''Manga/ShinjiIkariRaisingProject''.
** ''2nd Impression'', a lesser known ''Evangelion'' game for the SegaSaturn, had Mayumi Yamagishi. She was the MegaNekko before [[Anime/RebuildOfEvangelion Mari]] came around.
* In her ''Franchise/ResidentEvil'' novelizations, S.D. Perry introduced Trent, a renegade member of the Umbrella board of directors. His role was to fill all the glaring {{Plot Hole}}s in the games by pulling strings from behind the scenes and assisting the heroes while sabotaging Umbrella's plans.
** The two original ''Resident Evil'' novels, ''Underworld'' and ''Caliban Cove'', were written back before the release of ''VideoGame/ResidentEvil3Nemesis''. Two of the characters introduced therein, John Andrews and David Trapp of the Exeter S.T.A.R.S. unit, have a small fan following and occasionally appear to this day in fanfiction.
* Due to being {{retcon}}ned, anything having to do with the original SNES ''VideoGame/{{Star Fox|1}}'' and the [[VaporWare unreleased]] ''VideoGame/StarFox2'' were rendered non-canon. Two new pilots from ''2'', Fay and Miyu (a poodle and a lynx, respectively), are considered foreigners. With them is [[FauxActionGirl Fara Phoenix]] from the Magazine/NintendoPower comic adaptation of the original game.
* All the main characters in ''VideoGame/DiscworldNoir''. Canon characters such as Gaspode and Nobby Nobbs are limited to secondary roles. There is certainly no indication in the books that Lewton, or even the profession of PrivateDetective, exists.
* ''VideoGame/TheSimpsons'' Arcade Game gives us all the bad guys in the game except for Mr. Burns, Smithers, the wrestler boss, and the drunk boss.
* The fan-made ''[[VideoGame/StreetsOfRage Streets of Rage Remake]]'' gives us the female ninja Rudra, who serves as a boss character (depending on which path you take in the story) and is also an unlockable character. Interestingly, she started out as a joke sketch which the artist posted on a forum and claimed that she was [[TheDragon Shiva's]] sister, but a lot of fans didn't get the joke and thought she was real. During the fan-remake's development, [[WhatCouldHaveBeen Rudra was going to actually be Shiva's sister]], but prior to the final draft's development and release the creators went in a different direction with her, turning her into more of a mercenary character who works for the Syndicate as a hired assassin.
* There are plenty of Canon Foreigners in some ''Literature/TheLordOfTheRings'' games.
** ''VideoGame/TheLordOfTheRingsOnline'' is especially guilty.
** In ''War in the North'', there's the main party of Andriel the Elf, Eradan the Ranger, Farin the Dwarf and their Great Eagle companion Beleram. There's also the BigBad Agandaűr, one of the chief lieutenants of Sauron.
*** Technically speaking, Agandaűr could be interpreted as an OCStandIn given that he matches the description of a messenger who knocks on King Dáin's door in ''Fellowship of the Ring''.
** ''VideoGame/TheLordOfTheRingsTheThirdAge'' gets the same treatment with their own main party: Berethor the Gondorian soldier, Elegost the Ranger, Hadhod the Dwarf, Eaoden the Rider of Rohan, Morwen the Shield-maiden, and Idrial the Elf.
** Then there's ''Battle for Middle-earth II''. Both the original and ''The Rise of the Witch-King''. Especially for the Evil Armies - including the Goblin King Gorkil, Hwaldar the Wildman serving under the Witch-King, Drogoth the Dragon Lord, Rogash the troll, and Karsh a celebrated Hero turned Leader of the Great Plague. Create-a-Hero mode has the ''The Lord of the Rings: The Third Age'' characters Berethor, Hadhod, Morwen and Idrial as starter heroes.
** ''VideoGame/TheLordOfTheRingsWarOfTheRing'' has a female Haradrim assassin named Saleme.
** The 2003 video game ''VideoGame/{{The Hobbit|2003}}'', also made by Sierra Entertainment, has Balfor, a Dwarf; Lianna, an Elf; and Corwin, a man.
** ''Middle-earth: Shadow of Mordor'''s Talion, ranger of Gondor.
* The American release of ''VideoGame/SuperMarioBros2'' was an altered version of a non-Mario game, ''VideoGame/DokiDokiPanic''. Several of the enemies featured, like the Shy Guys and Snifits, were later used in ''VideoGame/YoshisIsland'', and more frequently in the Mario franchise from then on.
* The multiplayer-focused ''VideoGame/{{Rayman}}'' SpinOff game ''Videogame/RaymanM'' introduced the characters Tily and Razorwife and a new robo-pirate model, Henchman 1000, none of whom have made any appearances in the main series.
* Most aspects of ''TabletopGame/ForgottenRealms'' video games are this, as some games don't have [[DerivativeWorks an accompanying novel]] and it's difficult to integrate StoryBranching into canon.
* ''VideoGame/SaiyukiJourneyWest'' adds several totally-new characters to the cast of the traditional novel, like the dryad Lady Kikka and most of the secret characters.

[[folder:Web Original]]
* Donovan Corbett in ''WebVideo/StreetFighterTheLaterYears''
* [[WebVideo/AtopTheFourthWall Lewis Lovhaug]] is the [[Series/PowerRangersZeo White Zeo Ranger.]]
* The Creator/RichardEGrant Ninth Doctor from the ''Series/DoctorWho'' web animation ''Scream of the Shalka'', and his companion Alison Cheney.
* ''RolePlay/PokemonDigimonMonWars'': While set in the Anime/{{Pokemon}} anime, characters from PokemonSpecial and the games themselves may appear, even though they had yet to show up in the anime. Same could be said on the Franchise/{{Digimon}} with characters outside ''Anime/DigimonAdventure''.
* ''WebVideo/UltraFastPony'' is an [[TheAbridgedSeries abridged series]] that nevertheless has a few original characters thanks to creative editing. There's Snuggle Berry, who's referred to a few times but never appears on-screen--and dies in the same episode she was introduced in. There's also Mutation: in ''UFP'' she's a separate character, but in the original canon she was just a shared secret identity.
* ''Webcomic/TheGlassScientists'' keeps a lot of characters from ''Literature/TheStrangeCaseOfDrJekyllAndMrHyde'' and other victorian novels, but Jasper, a werewolf AudienceSurrogate, is a new addition.
[[/folder]]

[[folder:Western Animation]]
* The King of this trope would have to be Franchise/SonicTheHedgehog. ''WesternAnimation/SonicSatAM'', has the most memorable ones. Princess Sally, Bunnie Rabbot, Rotor the Walrus, Antoine, Uncle Chuck, and Snively became amazingly popular.
** It's worth noting that the Freedom Fighters were originally based roughly off the small captive animals of the original games, even retaining their western names. However the concept was revamped before production and only a redesigned Sally Acorn (aka "Ricky") remained (though Rotor and Bunnie are arguably based off of Joe Sushi and Johnny Lightfoot respectively). Interestingly some of the Freedom Fighters (including the remodelled Sally for the show) cameoed in ''VideoGame/SonicTheHedgehogSpinball'' and were intended to be playable characters in canned titles, making for a somewhat complex CanonImmigrant.
** Then there are LoadsAndLoadsOfCharacters from ''WesternAnimation/AdventuresOfSonicTheHedgehog'', such as [[MadScientist Prof Von Schlemer]], [[TheAce McHopper]], and [[HonestJohnsDealership Wes Weasley]].
** Also, almost the entire cast of ''WesternAnimation/SonicUnderground''.
** Sticks the Badger in ''WesternAnimation/SonicBoom''.
* Floyd from ''WesternAnimation/BabyLooneyTunes''.
* All three ''Franchise/TeenageMutantNinjaTurtles'' cartoons are the absolute kings of this trope, with dozens of these characters per series (a trend that continued for each added alternate adaptation made from the original comic book, as seen above). The most notable ones are Krang, Bebop and Rocksteady from the [[WesternAnimation/TeenageMutantNinjaTurtles1987 Fred Wolf cartoon]], and Cody Jones, Agent Bishop, and Hun from the [[WesternAnimation/TeenageMutantNinjaTurtles2003 4Kids series]]. [[CanonImmigrant Hun later made it into a comic.]]
* Comicbook/{{Storm}}'s nephew Spyke, JerkJock Duncan Matthews, Hungan, and Morlocks members Facade, Lucid, and Torpid from ''WesternAnimation/XMenEvolution''. Comicbook/{{X 23}} was altered a bit before becoming a CanonImmigrant.
-->"This X-23 character is pretty popular among kids ... we should bring her into comics."
-->"Let's make her a child prostitute!"
-->"BRILLIANT!"
** Spyke is a sort of example. A character with similar powers named Spike appeared in ''Comicbook/XForce'', while a canonical nephew of Storm was introduced in ''Comicbook/BlackPanther''. His name is David Evan Munroe (his middle name is a ShoutOut to Spyke, whose name was Evan), but it hasn't yet been established whether or not he's a mutant.
** Another Spyke {{Expy}} named Spike appeared in ''Film/XMenTheLastStand''.
* Harry Grimoire, wizard in training and friend of Felicia, of the ill-fated ''WesternAnimation/{{Darkstalkers}}'' cartoon. While he looks like a total ripoff of Literature/HarryPotter, he does in fact pre-date Rowling's work. Also, there is Hairball, Sasquatch's nephew, who bravely fended off Demitri. Klaus, Victor's stout butler also qualifies. Terramon, the health inspector and Pyron's brother from the last episode. Dracula and Van Helsing may or may not count, as they are {{Public Domain Character}}s.
* Red Claw, Summer Gleeson, Joan Leland, Maven, Baby Doll, Roland Daggett, Calender Girl, Kyodai Ken, and H.A.R.D.A.C. from ''WesternAnimation/BatmanTheAnimatedSeries'', plus ComicBook/HarleyQuinn, Renee Montoya, Gray Ghost, Roxy Rocket and Lock-Up, five successful {{Canon Immigrant}}s. There's also various one-off supporting characters like Veronica Vreeland or Batman's mechanics Earl and Marva Cooper. It should be noted, though, Summer is basically an {{expy}} of Vicki Vale.
* Ethan Bennett, Chief Angel Rojas, the Kabuki Twins, Temblor, Rumor, and Scorn (but ''not'' Wrath, who was just very obscure) from ''WesternAnimation/TheBatman''. Ellen Yin may seem like this, but she is actually a RaceLift of Ellen Yindel, the obscure female police commissioner from ''Comicbook/BatmanTheDarkKnightReturns''. There's also Smoke and Blaze, two female sidekicks of Mirror Master and Firefly. However, Scorn became a CanonImmigrant, Rojas is basically a [[RaceLift Hispanic]] Harvey Bullock, and Ethan is a {{composite|Character}} of Crispus Allen [[spoiler: and ComicBook/TwoFace with Clayface's powers and codename]].
* Everyone in ''WesternAnimation/BatmanBeyond'' except Bruce Wayne, Barbara Gordon, and Mister Freeze. Prominent examples would be Terry [=McGinnis=] and his family, Max Gibson, Barbara's husband Sam, and every member of the [[Franchise/JusticeLeagueOfAmerica JLU]] except Superman and Big Barda. Terry himself would eventually become a CanonImmigrant.
* Kru'll the Eternal, Music Meister, Equinox, Baby Face, Fun Haus, and Scream Queen from ''WesternAnimation/BatmanTheBraveAndTheBold''. There were also a few supporting characters like ComicBook/PlasticMan's wife Ramona. However, Kru'll is {{composite|Character}} of [[ComicBook/{{Shazam}} King Kull]] and ComicBook/VandalSavage and Fun Haus is an {{expy}} of the Jack Nimball Toyman.
* From [[WesternAnimation/AroundTheWorldInEightyDays the 1972]] [[AnimatedAdaptation adaptation]] of ''Literature/AroundTheWorldInEightyDays'' come Lord Maze, his niece Belinda, whom Phileas Fogg wants to marry, and Passpartout's [[TeamPet pet]] [[EverythingsBetterWithMonkeys monkey]] Toto.
* Bruiser the Betelgeusian berserker baboon from the ''ComicBook/BuckyOHareAndTheToadWars'' animated series.
* Bluster Kong and Eddie the Mean Old Yeti from ''WesternAnimation/DonkeyKongCountry''. Also, Captain Scurvy and Kong Fu. [[note]] though Captain Scurvy is himself an expy of Captain K. Rool from ''DonkeyKongCountry2'' [[/note]]
* Godzookie from the 70s ''[[WesternAnimation/TheGodzillaPowerHour Godzilla]]''.
* Eugene and Amani from ''The New Archies''.
* Indira "Indy" Daimonji and any villain who wasn't Electro, the Lizard, the Kingpin, Kraven, or SilverSable in ''WesternAnimation/SpiderManTheNewAnimatedSeries''. Though Talon is an admitted CaptainErsatz of Black Cat, whom she was initially intended to be before the producers snagged female rapper Eve for the part and [[RaceLift changed the character's appearance accordingly]].
* Hypnotia and Elastika from ''WesternAnimation/IronMan''.
* Most of the villains from ''WesternAnimation/StaticShock'' were created for the series, with the major exceptions being Hot-Streak and Rubberband Man. Richie Foley (AKA Gear) and She-Bang were also created for the show, though the former was a CaptainErsatz of Rick Stone, Static's buddy from the comics.
* Gopher from the [[Franchise/DisneyAnimatedCanon Disney version]] of ''Disney/TheManyAdventuresOfWinnieThePooh.'' He {{lampshade|Hanging}}s this constantly -- his CatchPhrase is "I'm not in the book!"
** Darby, Christopher Robin's SuspiciouslySimilarSubstitute in ''My Friends Tigger and Pooh''.
** Kessie the bluebird. Introduced in a few episodes of ''WesternAnimation/TheNewAdventuresOfWinnieThePooh'', before becoming a regular character in ''The Book of Pooh''.
** Lumpy the Heffalump as well.
* The Geek, a female child companion to ''WesternAnimation/SamAndMaxFreelancePolice'', was created for the kid-friendly cartoon series. She was, however, created by the creator of the original comic books, with a light dash of ExecutiveMeddling: originally he created The Geek as a male character, ''intended'' to make the series more kid's-TV-friendly, but when the network suggested Max be made female, he opted to make The Geek female instead. (A much more acceptable compromise.)
* Comicbook/{{Blade}}'s mentor, Whistler, in ''WesternAnimation/SpiderManTheAnimatedSeries'', where his two main functions are to [[MrExposition exposit]] about Blade and vampires and to convince Blade to trust and cooperate with the other heroes. In fact, Whistler was created for the animated series and reused in the movie, and is an interesting example of canon foreigner existing in two mediums without becoming a full CanonImmigrant. However, he's a {{composite|Character}} of Jamal Afari (Blade's mentor) and "Bible" John Carik (looks and personality).
* Skeeter from ''WesternAnimation/MuppetBabies''. While Skeeter has never appeared as a Muppet proper, she did appear in the "Muppet Teens" series of books, which was the ''WesternAnimation/MuppetBabies'' as teenagers. [[spoiler: Oh, and as a grown-up in an issue of ''ComicBook/TheMuppetShowComicBook'']].
* 3/4 of the characters from ''Series/TheSuperMarioBrosSuperShow'', ''WesternAnimation/TheAdventuresOfSuperMarioBros3'', and ''WesternAnimation/SuperMarioWorld'' cartoons have never been (and likely will never be) seen in the games. Most notably Oogtar and every other caveman character inhabiting Dinosaur Land in ''Super Mario World'', every character based off a movie or story in ''Super Show'', and every single character from the 'real world/Earth' in the first two cartoons.
* ''WesternAnimation/JusticeLeague'' and ''Unlimited'' used a bunch of characters who split the difference between Canon Foreigner and {{Expy}}:
** Hro Talak is Comicbook/{{Hawkman}}, only evil. Except he can't be Hawkman, because the ''real'' Hawkman ([[CompositeCharacter Carter Hall/Katar Hol]]) appeared in a later season. DC [[ExecutiveVeto didn't allow]] the writers to make Hawkman evil. ''Hro Talak'' is an anagram of ''Katar Hol''.
** Galatea is ComicBook/PowerGirl, except she's a clone of Comicbook/{{Supergirl}} rather than an AlternateUniverse counterpart. And she's [[AdaptationalVillainy evil]].
** The Ultimen are the ComicBook/WonderTwins and the other original "[[CaptainEthnic ethnic]]" characters from ''WesternAnimation/SuperFriends'', only competent. And they're clones created by the GovernmentConspiracy.
** The Justice Guild is the [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] Comicbook/JusticeSocietyOfAmerica (with a little bit of Creator/AdamWest as ''Series/{{Batman}}'' for flavor).
** Devil Ray is practically Black Manta, only he's a nemesis of Franchise/WonderWoman instead of Comicbook/{{Aquaman}} (who could not be used in the later seasons due to the unsold Aquaman pilot).
** And in a cross-company example, the Justice Lords are versions of the JLA who became corrupted by their abilities and all but conquered Earth for "the greater good", only to be betrayed by their Batman. In other words, the Comicbook/SquadronSupreme. WordOfGod also stated they were based on ''ComocBook/TheAuthority''. The Justice Lord became CanonImmigrants as of ''ComicBook/TheMultiversity''.
** Tsukuri and Aresia are [[AdaptationalVillainy evil versions]] of Comicbook/{{Katana}} and [[Comicbook/InfinityInc Fury]].
* For ''WesternAnimation/TheFairlyOddParents'', the Copper Cranium and the Gilded Arches show up only in the Crimson Chin webtoon. Arches later appeared in a video game. [[Theatre/AMidsummerNightsDream King Oberon, Queen Titania]], and the Shadow only appear in the video game ''Shadow Showdown''
* Eva Skinner[[spoiler:/XANA]] and about ten other one-off characters are introduced in the ''WesternAnimation/CodeLyoko'' novels.
* ''WesternAnimation/TheLegendOfZelda'' animated series had several of these, including Zelda's father King Harkinian, the fairy Spryte, and every other character to appear who wasn't Link, Zelda, or Ganon.
** While Spryte herself didn't become a CanonImmigrant, the idea of Link having a fairy companion began here, and has been seen in a few games.
* Mostly {{averted|Trope}} in ''WesternAnimation/TheSpectacularSpiderMan'' as much as any adaptation probably can--the creators decided that every named character should be someone from ''Franchise/SpiderMan'' canon, and more or less stuck to it, even with minor characters like Comicbook/NormanOsborn's assistant, the high school drama teacher, etc.
* ''WesternAnimation/UltimateSpiderMan'' has Mac Porter, the head of ''ComicBook/DamageControl'' and [[ComicBookFantasyCasting a loving]] [[InkSuitActor tribute]] to deceased comic creator Creator/DwayneMcDuffie, who created ''Damage Control''. There's also the Plymouth Rocker, Salem's Witch (a possible ShoutOut to Comicbook/ScarletWitch) and Slam Adams, a trio of [[CaptainGeographic Boston-based supervillains]].
* Lightwave, Iceman's half-sister from ''WesternAnimation/SpiderManAndHisAmazingFriends''.
* Alexis Luthor and Kell-El/Superman X from ''WesternAnimation/LegionOfSuperheroes''. Though the latter is essentially a CompositeCharacter of ComicBook/{{Superboy}} and Mon-El.
* ''WesternAnimation/YoungJustice'' primarily averts this (see ''WesternAnimation/TheSpectacularSpiderMan'' by the same creator), but introduced a new Aqualad, who was [[CanonImmigrant adapted to the comics]] before the show even aired. There's also [[LegionOfDoom the villainous organization]] called [[TheOmniscientCouncilOfVagueness The Light]], though the actual members are all existing characters and it's really The Secret Society undergoing AdaptationNameChange.
** {{Averted|Trope}} with Artemis; after much confusion by fans, she turned out to be an adaptation of Artemis Crock, the minor comics villainess Tigress. Though she ''did'' get her own version in the comics... before she got StuffedIntoTheFridge five pages in.
** A proper example would be the Terror Twins, a pair of teen villains created for the show, and Green Beetle, a Martian with the same sort of Scarab used by Comicbook/BlueBeetle.
** The tie-in comic gives Robin three new relatives: a cousin and aunt who die along with his parents, and an uncle who survived, but was crippled and couldn't care for him. For bonus points, WordOfGod reveals that Robin is named after his uncle, who went by Rick-- offering an explanation for why a show taking place "now" would feature a kid named ''Dick.''
* Ruby, the red ninja created for ''WesternAnimation/MortalKombatDefendersOfTheRealm''. Though a red female ninja named Skarlet was eventually introduced in the video game canon, she has nothing in common with Ruby other than the basic color motif.
* ''WesternAnimation/TeenTitans'' had a metric ton of these. Most of the time they were to act as supporting characters or the MonsterOfTheWeek. A small handful (Mas y Menos, Billy Numerous, Cinderblock) [[CanonImmigrant managed to make it]] into [[ComicBook/TeenTitans the comics]].
* ''WesternAnimation/SupermanTheAnimatedSeries'' had quite a few with Volcana, Luminus, the Preserver, Sgt. Corey Mills, General Hardcastle, Detective Kurt Bowman, Darci Mason, Angela Chen, and Unity. Mercy Graves and Livewire started here and became {{Canon Immigrant}}s.
* ''WesternAnimation/HeroesOnHotWheels'' was actually based on a French comic book called ''ComicBook/MichelVaillant''. The characters of Frank (Michel's younger brother), Hanna (Frank's photographer girlfriend), Quincy (Team Vaillante's mechanic) and Fox (one of Team Leader's racers) were not in the original comics.
* ''WesternAnimation/GreenLanternTheAnimatedSeries'' has Razer, the new Red Lantern. There's also a few original Green Lanterns who were made to provide CannonFodder like Dulok, M'Ten and Shyir Rev. Many of the [[MonsterOfTheWeek villains of the Week]], such as General Zartok and Drusa, were also created for the show.
* ''WesternAnimation/DuckTales'' primarily based off the Creator/CarlBarks Uncle Scrooge comics, had Launchpad [=McQuack=], Mrs. Beakly, Duckworth (Scrooge's butler is always some stock character in the comics), Gizmo-Duck, Bubba Duck, and Doofus Drake. There was also Webbigail Vanderquack, who was an expy of Daisy Duck's nieces from the comics.
* [[WesternAnimation/SabrinaAndTheGroovieGoolies The Groovie Goolies]] were ''Sabrina, the Teenage Witch'' spinoffs... but from her animated series, not the Franchise/ArchieComics [[Comicbook/SabrinaTheTeenageWitch comic book]]. The characters were owned by Filmation, and never appeared in Archie Comics (or comic books from any other company, for that matter.)
* Lily Bobtail and her family in Creator/CBeebies' ''WesternAnimation/PeterRabbit'' animated series.
* In the ''Literature/RainbowMagic'' movie, Lydia, her girl posse, and the snowmen were created for the movie.
* Francois (Esmeralda's brother), Dennis the monk and Angelica (Esmeralda and Francois' adoptive grandmother), in ''WesternAnimation/TheMagicalAdventuresOfQuasimodo''.
* The DiC adaptation of ''WesternAnimation/DennisTheMenace'' introduced [[GadgeteerGenius PeeBee Kappa]], [[BlackBestFriend Jay Weldon]], Lars, Mr. Cavallini and Professor Mentalapse.
* Harold, Gawain and many others in IvanhoeTheKingsKnight.
