Canon Immigrant

The adaptation is a wonderful place, where new ideas can frolic without having to worry about fitting into the canon. However, sometimes an idea is so interesting that the people who create the canon decide it deserves to be included.

Thus, we have the canon immigrant, who is a character created and nurtured in another medium and, eventually, imported back into the original. Note that, often, surface details are brought in to play off a new movie or TV series; this isn't that. Rather, it's usually a completely new character, who over time becomes more and more popular with the fandom, often filling some niche that was never quite complete before. As a recurring trend, these tend to be female characters (likely to be "spunky") who serve to break up an otherwise male Rogues Gallery or ally contingent.

If they're successful enough, they'll be included in new entries in the expanded universe, cross-pollinating concepts. Canon immigrants are often part of an adaptation distillation, and new, canonical version usually has extra details to tie them into the more complex backstory of the original.

One should always be aware of the Canon Rule of Cherrypicking and Broad Strokes: the fact that one or two elements from an Alternate Continuity or expanded universe have made their way into canon does not make the rest of the alternate continuity or expanded universe canon, as a whole.

A character is more likely to become a canon immigrant, and be embraced as such, if s/he is God Created Canon Foreigner.

This applies exclusively to characters or concepts who make the move from adaptation to original material. When dealing with alterations to existing canon that ends up changing the original material, see Ret Canon.

This is what every Canon Foreigner strives to be.

    Anime and Manga 
  • El Hazard (the TV series) featured a goofy and silly version of the "ultimate weapon android" Ifurita, as opposed to the far more serious and angsty Ifurita from the original OAV continuity. However, her popularity led to her being written into the latter continuity via the Radio Dramas, where her name was changed to "Ifurina."
  • Ryo Akiyama from Digimon Tamers and his Digimon don't seem to follow the same rules as the others. This is because he is from the Alternate Universe where the Digimon Adventure series took place. This is explained in the series of video games of which he is the star. To drive the point home, he is not in the manga that was later adapted from the series.
    • Unfortunately for Western fans, his games were on the Wonderswan, a handheld that was never released outside Asia. The first of these games got an English translation for Hong Kong, but the translation sucked. When he did turn up in Tamers, there was naturally massive confusion, as without the games to explain his backstory, he seemed to make absolutely no sense as a character. Interestingly enough, he's a different kind of Canon Immigrant, his games are canon to the Digimon Adventure universe, he cameoed in Our War Game, and then twice in Digimon Adventure 02, and is a vital part of Ken's backstory. He moved to the Tamers universe after ZeedMilleniummon's final defeat, effectively immigrating from one universe to another.
    • Due to the wildly different animation styles of the movies and Tamers, Ryo being in Tamers didn't cause much confusion: your average American Digimon fan had no idea that Ryo was supposed to be that guy in a couple shots of the movie (as a background character and Continuity Nod; if you didn't know who he was beforehand you had absolutely no reason to take note of him.) "Who is that guy we mostly see from behind with Ken in the origin story, and what was that monster-thing" was a major question, though, and even once fans did know, the decision to make a video game that necessary to understand what is going on in the show came to be seen as further evidence of season two's Seasonal Rot.
  • Black Butler the Musical II: The Most Beautiful DEATH In The World introduces two original grim reaper characters, Eric and Alan, whose story forms the core of the musical. They have appeared in cameos in both the manga and both the Black Butler II OV As and Book of Circus anime.
  • Tokyo Mew Mew imported everything but characters from the anime after it Overtook the Manga. The girls originally didn't use transformation phrases, for one...
  • Mai-Otome 0~S.ifr~, the anime prequel to Mai-Otome, features Mayo and Shion, characters originally from the Mai-HiME Destiny Light Novels taking place in an Alternate Continuity to Mai Hi ME. A rare example of trans-continuity, trans-setting promotion to canon.
  • Neon Genesis Evangelion:
    • Mana Kirishima first appeared in the video game Girlfriend of Steel, but proved popular enough that she later appeared in the unrelated Shinji Ikari Raising Project game and manga.
    • The Shinji Ikari Raising Project game introduced three new NERV technicians named Kaede, Satsuki, and Aoi. The three would later appear in the Alternate Universe manga Neon Genesis Evangelion: Campus Apocalypse. However, none of them have actually immigrated back into the anime canon, or even the Rebuild of Evangelion movies.
    • Speaking of Rebuild, someone who looks a lot like Mari Makinami makes a brief appearance in the last chapter of the manga.
  • Mazinkaiser was born out of the idea of giving the Mazinger Z a Mid-Season Upgrade for Kouji Kabuto in Super Robot Wars F Final. Developer Banpresto asked Go Nagai, Mazinger's creator, to design it; not only were players pleasantly surprised with the upgrade, but the reception of its appearance allowed Nagai to quickly incorporate the Mazinkaiser into Mazinger canon.
  • Mei Sakura, a character created for the Love Hina anime, was not only inducted into the manga at its very end, but Akamatsu then transplanted her into Mahou Sensei Negima!, causing many fans to wonder if they're one and the same person.
  • In Detective Conan, Inspector Shiratori was originally movie-only (and holding one rank lower) and Detective Takagi was originally used only in fillers. A number of minor police inspectors were named after their voice actors.
  • In ARIA, Ai was originally anime-only character, but starts to appear in special chapter in various guidebooks, culminating in becoming Akari's apprentice in the last manga chapter (and anime episode).
  • The VB-6 König Monster first appeared in the PlayStation game Macross Digital Mision VF-X. Macross Frontier is the first animated Macross series in which it has appeared. Fan theory holds that it got its due to its awesome, gigantic toy.
    • Also from Macross, though possibly a coincidence, the idea of controlling Veritech fighters with a brain interface showed up in the American Robotech tie-in novels several years before they were introduced to Macross canon in Macross Plus.
  • Dragon Ball Z has one in the form of Goku's father Bardock. Reportedly, Akira Toriyama liked the Bardock movie special so much he including him in the manga, in a brief two-panel flashback. Dragon Ball Kai, a recut of the anime which sheds off the majority of the filler, actually makes Bardock's death the prologue to the series.
  • In Saint Seiya, the special brainwashing technique of the Pope, the Genrou Maouken, appeared first in the anime before being introduced by the author in the manga. Similar is the case of the character Lyra Orpheus from the 2nd film, who's later seen (redesigned) into the manga continuity (though Kurumada made the design sketches for the movie enemies).
  • Future GPX Cyber Formula: Seiichirou Shiba, Rena Yuuki and Sera Gallagher all first appeared in the PlayStation game The New Challenger and they later were put into the extra ending of Sin.
    • Also Aya Stanford, who appeared in the Sin OVA and some episodes in Saga, was a character originally created for the first SAGA drama CDs.
  • Rai the protagonist of a video game spinoff, or someone that looks very much like him, appeared in Code Geass R2 for a few moments.
    • Similarly, Nonette Ennagram (the Knight of Nine, who's name is derived from two words meaning nine) appears in R2 when the Knights of the Round are revealed... She never appears again. Some fans have taken this to mean that she's the only Round who hasn't tried to kill Lelouch, and one of the few Rounds to survive the events of the series.
    • Marika Soresi and Liliana Vergamon, two characters used to expound on Cornelia's opinions of events in the novels while acting as her wingmen, appear alongside Britannian Ace and Knight Of Round Luciano Bradley in Code Geass R2. They die immediately.
  • In the Guyver anime film Out of Control, the villainous Guyver II was given a Gender Flip. This female version of Guyver II was incorporated into the manga as another character named Valkyria.
  • The Gundam video game series SD Gundam G Generation features a number of Original Generation mecha in order to spice things up. So far, only one of these has filtered back into the source material: the Gundam Belphagor, from Gundam X's After War time line, which shows up in the sequel manga Under The Moonlight.
    • Gundam actually has quite a lot of these. Mechs that only appear in MSV model kit lines have been showing up in subsequent anime productions since Zeta Gundam, Gundam Unicorn being a particularly massive example, which also brings in the Gustav Karl mobile suit from Hathaway's Flash.
    • One of the most obscure ones comes in the form of the Perfect Gundam, an armor upgrade for the RX-78-2 Gundam from the original series that debuted in an obscure manga called Plamo Kyo Shiro, where it was a kitbash plastic model created by the title character and scanned in to a VR game to battle against other models (a premise later used for the mostly unrelated Gunpla Builders Beginning G). It has since gone on to appear as an upgrade for the actual Gundam in various video games, notably the G-Gen series. The Perfect Gundam finally appears in animated form in the season 1 finale of Gundam Build Fighters (which also users a similar premise to the aforementioned Plamo Kyo Shiro and Gnpla Builders Beginning G), in that episode it is piloted by Takeshi Iori, the runner up for the second world championships and the father of the protagonist.
    • The latest example is the Perfect Strike Gundam from the Gundam SEED remaster. After the Strike Gundam model kits were released, a common project for model collectors was to build a version of the Strike with all three Striker Packs equipped at once. Someone at Bandai must have liked the idea, because the Perfect Strike appears in the latter half of the remastered Gundam SEED, upgraded from the original Strike.
    • Probably the oddest one of the bunch are the Mobile Suit Gundam Wing: Endless Waltz redesigns of the original five Gundams of Mobile Suit Gundam Wing. All five made their first appearance as just drawings. Wing would be the first to make a move, becoming a hidden unit in Super Robot Wars Alpha 2, then an event unit in SD Gundam Capsule Fighter before officially appearing in the remake manga Glory of Losers with the other four.
  • Naruto:
    • A certain pair of lightning-powered swords from a filler arc in the anime ends up showing up in the manga being wielded by a former member of the Seven Swordsman of the Mist, albeit with a slightly different design.
    • The guy who actually wielded said swords in the before-mentioned filler arc ends up showing up in the manga himself, during a flashback.
    • Gari from the Hidden Stone Village, Chukichi of the Hidden Mist Village, Pakura of the Hidden Sand Village and Toroi of the Hidden Cloud Village were all originally from the sixth Naruto movie. They made their appearance in the manga during the Fourth Ninja War arc.
    • The infamous episode 167 of Shippuden had 6-tailed Naruto perform 2 anime-original moves: a Rapid-Fire Tailed Beast Bomb and a Tailed Beast Laser. In chapter 610, both Killer Bee and Naruto used the former on the Juubi, while the Juubi used the latter on the two.
    • Mecha-Naruto was created for the video game Ultimate Ninja Storm Revolution, and was brought into the anime for a filler arc made to promote the game. Despite the arc airing around the game of the game's release, Mecha-Naruto's origin and storyline had to be slighty altered to better fit the show's continuity.
    • Sakura's parents, Mebuki and Kizashi Haruno, were designed by Kishimoto and introduced in Road to Ninja. However, they never appeared in the manga, but were confirmed to be canon characters by Kishimoto himself. While not appearing in the main manga series, they did make a cameo in a spin-off manga.
    • The Naruto Hiden light novels have canonized a number of things introduced in anime Filler and the Non-Serial Movies, though they still had to change a number of details to make them canon-compliant.
  • Musashi Tomoe from Getter Robo is an example that it might seem surprising to fans, but in Ken Ishikawa's original manga, Getter-3 was piloted by Professor Saotome. Musashi was created to fill that spot in the anime adaptation, and Ishikawa liked him so much that he was imported back into the manga and has subsequently become a central and fan-beloved member of the Getter family.
  • Dororon Enpi-chan is a boderline erotic 4koma parody of Go Nagai's Dororon Enma-kun with with main character being Enma's Distaff Counterpart. In recent remake, Dororon Enma-kun Meramera Enpi is introduced as the main villain and Enma's sister.
  • Minamo from Sketchbook first appeared in the anime incarnation, in which she is Daichi's little sister. She even has a rather big role, interacting a lot with the main character Sora, starting with the very first scene of the series—and she also participates in the art club's events later on. Perhaps the makers wanted to have a younger character to appeal to a larger demographic. She was re-introduced into the manga in chapter 97, about two years after the anime ended. Her first scenes in the manga imply that she has had prior interactions with the main cast, but the author stated in the notes that her Immigration into the manga continuity has no real meaning for the timing.
  • Trigun: The boomerang-wielding Descartes actually appeared in the first episode of the anime before showing up in the manga Trigun Maximum. Several other one-shot characters from the anime have make brief cameos when Vash flashes back to various people he's met in his journeys. Yasuhiro Nightow has actually stated that Vash's encounters with these characters in the anime episodes is canon within the manga's backstory, though that would mean that they'd be slightly different than the anime versions, since Meryl and Milly didn't meet Vash until the third chapter of the manga and thus wouldn't have been present.
  • There were rumors that Original Character Ayumi Sakigame of Pretty Cure All Stars New Stage would make the jump to Smile Pretty Cure! as a Sixth Ranger, but nothing of the sort happened. On the other hand, the items known as Miracle Lights, which made their first appearance in the Yes! Pretty Cure 5 movie, would bounce over to the All Stars movies, becoming an important part of how the movies play.
  • Several Yu-Gi-Oh! cards that were previously only in the anime, like Guardian Eatos, were made into real cards years later. The Dragons of Legend series of booster packs is specifically designed for this purpose.
  • In Wedding Peach, the Love Angels' outfits from the anime became their fighter outfits in the manga's Volume 3 as a reward for defeating Plulie.
  • Puella Magi Madoka Magica:
    • Puella Magi Madoka Magica Portable introduced five new witches, three of which are the witch forms of Homura, Kyoko and Mami. Given as such witches have not appeared in the main show and yet logically must exist in some form, it can be assumed that they are canon, but this is eventually confirmed in Rebellion, the movie sequel to the anime, which features Homulilly, Homura's witch, as the protagonist who doesn't even realize this.
    • Related to the above but less overtly canon, Candeloro (Mami's witch) appears in silhouette in one panel in "The Different Story", a seemingly canon manga. Similarly, Michiru Kazusa appears as well, corresponding with the same point in the plot that Mami appeared in Michiru's original manga. With all these connections, it wouldn't be a stretch to assume that all, or at least most of the spin-offs are intended to be canon, although it is still unclear if any of them will actually affect the main series.
  • Sgt. Frog: Several characters later in the series appeared in the anime before the manga, most notably Pururu and the casts of the 2nd and 4th movies. There's also Angol Fear, who made her first appearance in Soul Calibur IV. Of course, all those characters were originally created by Mine Yoshizaki anyway.

    Audio Play 
  • The Big Finish Doctor Who audio plays have their own Canon Immigrants brought in from the comic strips, mostly from Doctor Who Magazine: short episodes feature cuddly alien conqueror Beep the Meep and Time Lord construct Shayde, and there is a short and a full-length episode in which the Doctor's companion is shapeshifting penguin Frobisher.
    • The Company Of Friends is an Eighth Doctor play that features a 45-minute story for two people that were never in the Big Finish audios before — Fitz (books) and Izzy (comics).
      • For the longest time, Big Finish's works were of debatable canon, never officially being acknowledged by the show itself, but never being denied either. In a prequel to the 50th anniversary special called "The Night of The Doctor", the Eighth Doctor acknowledges and name-drops all of his audio-only companions, officially rendering Big Finish's stories and characters canon.

    Fan Works 
  • Advice And Trust: Chihiro Tanaka, a character originally created in Once More with Feeling is Shinji, Asuka and Rei's classmate and makes several appearances where she tries woo Shinji and pry him away from Asuka and Rei... with no success whatsoever.
  • Once More with Feeling: Someone asked the author if Mana Kirishima would show up. He answered: "Who is Mana Kirishima?". After looking for information about her, he stated she would show up, but nobody better count on it being more than one scene or her role being big.
  • Mechanic Wrench of the fic, Rainbow in the Dark, actually has her origins in an earlier piece by the author.
  • The Awakening of a Magus (an early Harry Potter fic the author stopped writing and removed it from Fanfiction.Net due to personal problems, although a copy still exists on fictionalley.org), had a Recursive Fic called Who Wants to Live Forever describing the death of a background character from over 3000 years ago (likewise removed due to being a songfic). Details of that description later made it into the Awakening.
  • The original Pokeumans series was sufficiently successful and had enough scope to prompt a community of fan series of its own. Ideas from these such as the evil mooks being called 'Extinctionists' and The Board of Dream Messengers were then accepted across the whole group and in the original series.
  • Reimagined Enterprise takes a number of plot details from the non-canon Star Trek Expanded Universe and uses them.
    • "Rihannsu" is the real name of the Romulans and "Romulans" is a human code name for them.
    • A version of the Optimum Movement from Star Trek: Federation appears as antagonists during the Post-Atomic Horror in the flashback in "Remembrance".
  • In Mega Man: Defender of the Human Race, a story based around the Mega Man cartoon and Classic game series, the leader of the Mega Crew is revealed to be Tiesel Bonne, from the Mega Man Legends games. Later, his siblings appear, and the Bonnes become supporting characters.
  • In Mega Man Reawakened, Big Name Fan Lizsama's Original Character, Elizabeth Marmalade, appears in Arc 3 with her permission.
    • The Neo Emerald Spears, who are based off the Emerald Spears from Archie Comics' Mega Man, appear in Arc 4.
    • Prism Man, who's exclusive to the Mega Man NT Warrior anime, appears in Arc 4.
  • On DC: United We Stand, in addition to the pre-existing examples of Canon Immigrants from DC Comics, there are also quite a few characters available who either had not appeared as of the time the roleplay is set, are adaptation-exclusive characters, or are from the New 52 reboot.
  • The Turnabout Storm novelization does this in regards to the Sirens from My Little Pony: Equestria Girls – Rainbow Rocks. Since the Sonata from Rainbow Rocks and the Sonata from Turnabout Storm share the same name, the Sirens get to be related in the following way: the mother of the Sonata in this story is Adagio, and her sister is Aria (who reminds Sonata of Maya).

    Film 
  • The Moorish character in Robin Hood, who in the last decade or so has cropped up in Film and TV, at least. The earliest incarnation seems to have been Nazir in Robin of Sherwood.
  • The 1998 American Godzilla officially became part of the Japanese Godzilla franchise with the release of the film Godzilla Final Wars and was even given the official name of "Zilla". Poking fun at the American rendition, unlike all the other monsters, which are depicted as men in latex costumes, Zilla is rendered in intentionally mediocre CGI.
    • He was referenced in an earlier film in which a character asks "Didn't Godzilla show up in New York recently?" and is told "That's what the Americans think."
    • And it doesn't stop there. Mothra, Rodan, Varan, Baragon, Kamoebas (a giant turtle from the obscure film Space Amoeba), Moguera (from another obscure film called The Mysterians), Meganulon, Manda (from yet another obscure film called Atragon) and King Kong were all stars in their own respective films before becoming part of the Godzilla franchise.
    • Frankenstein Conquers The World
      • It's known as Frankenstein vs. Baragon in Japan. It takes Frankenstein's Monster (who, not surprisingly, is mistakenly called "Frankenstein") growing to giant size and fighting Baragon.
  • Coruscant, the capital of the Old Republic and later the Galactic Empire in the Star Wars Universe, first appeared and was named in The Thrawn Trilogy by Timothy Zahn. It was finally made G-canon when The Phantom Menace was released.
    • The Star Wars Radio Dramas (1981) marked the first physical appearance of Bail Organa, Leia's adoptive father. He appeared in Attack of the Clones and Revenge of the Sith as the Republic senator from Alderaan, played by Jimmy Smits.
      • He actually appeared in earlier drafts of A New Hope and was mentioned by name in the shooting script, but not the completed film. His scenes were retained by the novelization and the comic book adaptation.
    • Quinlan Vos, a Jedi based on a character from the background in a shot from Tatooine, was given a story in the comics and novels. George Lucas loved the character so much that he intended to give him a scene in Revenge of the Sith, but due to time constraints, the scene was cut. He is, however, mentioned by name when Obi-Wan speaks to Anakin about the Outer Rim sieges.
    • Ditto with Aurra Sing, another cameo in Episode I that was given a backstory in the EU and elevated to G/T Canon in Star Wars: The Clone Wars.
    • Darth Bane has been elevated from C-Canon to G/T-Canon with the final arc of Star Wars: The Clone Wars.
    • The Disney-mandated end of the pre-2012 EU, and start of a new centralized story oversight team, has provided writers with plenty of opportunities to make EU elements canon now. For instance, Tarkin gave Governor Tarkin his first name of Wilhuff back and named several members of the Imperial Ruling Council who were previously only in the EU, such as Sate Pestage.
    • Likewise, Star Wars Rebels brought the Inquisitorius from the old EU into the current canon in a big way. The Grand Inquisitor serves as a major antagonist in the first season, while various other inquisitors appear as recurring villains in Season 2. Though while the Inquisitorius as an organization was taken from the EU, the actual inquisitors seen on the show are new characters.
    • Kylo Ren/ Ben Solo from The Force Awakens is basically a Composite Expy of several different Legends characters. He is essentially the film canon's version of Jacen Solo, who like Ben, is Han and Leia's son who turned to the Dark Side. He's named "Ben" after Ben Kenobi, just like Ben Skywalker, Luke's son from the novels. And he's Luke's former student who betrayed the New Jedi Order, like both Kyp Durron (who also sought out Darth Vader's burned remains like Kylo Ren) and Brakiss, though it's yet to be seen whether he'll make a Heel–Face Turn like Kyp did.
  • Mosasaurus appears in Jurassic World, after playing a prominent role in Jurassic Park: The Game. The Masrani website also talks about the Bri-bri natives of Isla Nublar relocated to the mainland in The '80s, who were first represented in Jurassic Park: The Game in the character of Nima Cruz.
  • Killer Tomatoes Eat France, the fourth and final Killer Tomatoes movie, features Zoltan and Ketchuck, two of Gangreen's tomato lackeys in the Attack of the Killer Tomatoes animated series. In addition, the film features a third tomato grunt named Viper, who is loosely based on the cartoon-exclusive tomato Fang.

    Gamebooks 
  • King Toadstool and Wooster, Super Mario Bros.-related characters introduced in Nintendo Comics System, made a few appearances in the Nintendo Adventure Books.
  • The Lone Wolf gamebook series had a short-running companion novel series called Legends of Lone Wolf, which covered and expanded upon the gamebook stories, including introducing several new characters. Demigoddess Alyss was introduced early into that series, and broke through the canon ceiling in Book 16 of the gamebook series.

    Literature 
  • Older Than Radio: None of the three most famous stories associated with the Arabian Nights—"Aladdin","Ali Baba and the Forty Thieves", and "Sinbad the Sailor"—were part of the collection as it was assembled in the Arab world over several centuries. All three were independent folk stories added to the Nights by Antoine Galland when he compiled his 18th century French translation, which introduced the Nights to European culture.
  • William Gillette's Sherlock Holmes play introduced the character of Billy the page-boy. When Arthur Conan Doyle later wrote a couple of Holmes plays himself (The Crown Diamond and an adaptation of The Speckled Band) he included this character, possibly for the sake of consistency with Gillette. Conan Doyle later adapted The Crown Diamond into a short story (The Mazarin Stone), and thus Billy entered into the Sherlock Holmes canon. He also received a very brief mention in a couple of the later canonical tales.
  • Happened with Raymond E. Feist's The Riftwar Cycle. The characters of Gorath, Owyn, Jazhara and Jimmy's twin brother Lysle Rigger all make their first appearances in the computer games Betrayal at Krondor and Return to Krondor, set in Feist's world. They were then incorporated into canon when Feist wrote a novelization for both games and made references to them in later books.
  • Margo Lane appeared first on The Shadow radio show before Walter Gibson incorporated her into the prose series. Earlier novels of the Shadow often only barely featured women, but the radio show wanted vocal contrast.
  • Inspector Morse had a Canon Immigrant car. The original novels by Colin Dexter had Morse driving a nondescript modern vehicle, but the TV show gave him a Cool Car, a red 1960s Jaguar Mark II. The car became so iconic of the character that the novels written after the TV show started included it with no explanation of the change, even to the point of putting it on covers (art images, not photos from the show).
  • Ellery Queens secretary Nicky Porter was originally created for the radio show, but later appeared in two of the novels and a dozen short stories.
  • Hastur, a Great Old One in the Cthulhu Mythos, is actually a canon immigrant from The King in Yellow (well, sort of) with a name taken from an Ambrose Bierce story by way of August Derleth. Lovecraft, Derleth and Robert E. Howard were all friends and frequently borrowed and swapped ideas for deities and monsters.
  • A minor example: The Wizla Tobacco and Rolling Paper Company was first mentioned on the label of Albert's tobacco tin in the TV adaptation of Hogfather, before getting referenced several times in Unseen Academicals.
    • As revealed in the official Mort playscript, rather than try and duplicate the established appearance of Rincewind for the sake of a brief cameo, the Studio Theatre Club replaced him with their own nervous junior wizard character. They called him Stibbons.
    • In The Compleat Ankh-Morpork City Guide the list of cafes includes Cafe Ankh, and the pubs and taverns includes the Octarine Parrot, both from Discworld Noir.
  • Doris and Benny the Cab, created for the film Who Framed Roger Rabbit, appeared in the sequel to the original book. Another character created for the film, Teddy Valiant, is mentioned in the book, though he doesn't appear in either version because he was killed years ago.
    • Who P-P-P-Plugged Roger Rabbit? is really more of a sequel to the film than the book in most respects, including Toons being animated characters rather than comic strip characters, Roger being a good guy and being set in The Forties rather than The '80s.
  • Two famous British literary heroes had their backgrounds tweaked to reflect those of their actors in live action adaptations:
    • At first, Ian Fleming didn't like the casting of Sean Connery as James Bond. However, after seeing Dr. No, he made Bond's father, like Connery, a Scot.
    • Bernard Cornwell established his hero, Richard Sharpe, as born and raised in London. After Sean Bean portrayed the character for television, Cornwell added a previously unrevealed aspect of Sharpe's childhood. At age 15, Sharpe moved to Yorkshire, where he presumably gained an Oop North accent similar to the obviously-not-from-London Bean's.
    • Also the character of Rifleman Harris was created for the TV series and subsequently appeared in the novels because Cornwell liked him.
  • Havenite superspy Victor Cachat was first introduced by Eric Flint in a spin-off anthology Changer of Worls, in a short story which also made Anton Zilwicky an Ascended Extra. He had since became an iconic character and as much as a series' mascot as an eponymous protagonist herself. Though Flint in essence becoming Weber's equal partner in writing the series might have to do something with that.

    Live Action TV 
  • The first name of Uhura, of Star Trek: The Original Series. The name "Nyota" (Swahili for "star") was invented by William Rotsler for his 1982 book Star Trek II Biographies. It was approved by the original actress, Nichelle Nichols, and by series creator Gene Roddenberry. After wide use in the Star Trek Expanded Universe and All There in the Manual works it finally became canon in the 2009 film, Star Trek. As did the names of Captain Kirk's parents, George and Winona, coined by novelist Vonda N. McIntyre in Enterprise: The First Adventure. McIntyre also gave Mr. Sulu the first name Hikaru in her novel The Entropy Effect, and the name was canonized in Star Trek VI: The Undiscovered Country.
  • The Holodeck of the Star Trek: The Next Generation series, which started its life in Star Trek: The Animated Series. Kirk's middle name was first declared as "Tiberius" in the animated series as well (though it was conceived earlier, and Gene Roddenberry had previously used "Tiberius" as the middle name of the title character, William T. Rice, in his first TV series The Lieutenant).
    • Although that does conflict with the tombstone that Gary Mitchell conjures up in the second pilot, which reads James R. Kirk...
    • Add to that Lady Amanda's surname of Grayson, taken from "Yesteryear," the best known episode of ST:TAS.
    • Minor example: the most prominent new species of the animated series, the Caitians (M'ress) and Edoans/Edosians (Arex), are also canon immigrants: Caitian admirals appear in The Voyage Home and Edosians have been mentioned several times (for instance, Garak dealt with Edosian orchids while a gardener).
    • If plot points from originally non-canon works count, then the big, big one would be the entire episode "Yesteryear". Though the animated series was largely considered non-canon, this one episode gave us a lot about Vulcan culture and Spock's past that has been adhered to - its events were referenced in TNG's "Unification," Vulcan's Forge and sehlats were featured in the Vulcan trilogy on Star Trek: Enterprise, and the reboot movie's sequence with young Spock is taken nearly word-for-word from the episode.
      • While only referred to as a "teddy bear", the sehlat was actually first described in the episode Journey To Babel, so it may not qualify.
    • Synthehol, an alcohol substitute that gets one drunk, but the effects of intoxication can be dismissed at will, started life as a concept in the TNG novels and was soon written into the TV series.
    • "The Warrior's Anthem", a Klingon war hymn sung in DS9: "Soldiers of the Empire", originally appeared in the video game Star Trek: Klingon.
  • Doctor Who has occasionally dipped in its Expanded Universe, largely because of the former fanboys currently in charge.
  • In a comic about the character Spike from Angel, Spike is sent to an asylum for demons and meets an incredibly strange character... a human-sized, floating, telepathic Betta fish named Betta George. Apparently, when Joss Whedon approached the writer of these comics to collaborate on the canon continuation comic After The Fall, he noted "I like George. Let's find a place for him." The fans are reportedly somewhat squeamish about the inclusion of such a blatantly strange character in canon, despite the show's other eccentricities.
    • Illyria also appeared in another comic's canon and appears in Buffy season 9.
    • Beck, who also appeared in the Asylum mini-series and other Spike comics, appears in After The Fall.
  • Howard, Marina, and Pearl from Last of the Summer Wine. They started out in a stage play version of the show, and got a good enough reaction to become part of the TV cast.
  • The CSI villain Sqweegel. Anthony Zuiker's digital novel "Level 26 Dark Origins" has first White Sqweegel and at the end comes Black Sqweegel, the one who crossed to CSI. Word of God has confirmed the immigration on Level 26 website.
  • In Power Rangers, this is subverted with Zordon's home planet of Eltar. While Eltar Is first mentioned in the non-serial first movie, and not mentioned in the main canon until Power Rangers Turbo, the name has been in the Universe Bible since the beginning.
    • Likewise the Tengu (renamed Tengas) and the Rangers' ninja costumes and powers originated in the movie and were used in Mighty Morphin' Power Rangers Season 3, since the events of the movie were modified and retold in the series. The Zords don't quite count as they were based on the mecha from Ninja Sentai Kakuranger and most likely would have appeared in the series anyways even if the movie was not made.
    • The Battlizer from Power Rangers S.P.D. crossed over to its source material, Tokusou Sentai Dekaranger, the same yearnote  when they returned for its team-up movie with Magiranger.
    • While the term wasn't used for Gokai Silver's Gold mode from Kaizoku Sentai Gokaiger and Kyoryu Red's Carnival mode from Zyuden Sentai Kyoryuger, both modes do share traits from Power Rangers Battlizers, most notably, enhanced power armor, and a finisher.
    • The New Powers from Power Rangers Super Megaforce certainly count. These are Dairanger, Changeman, Flashman, Fiveman, and Maskman, five previously unadapted Super Sentai teams, thus were previously part of Sentai canon, but not Power Rangers canon.
  • The "Clue Crew" in Jeopardy! originated on the short-lived kids' version Jep!, there called the "Jep! Squad".

    Music 
  • The Beatles had a problem with the soundtrack to their television film Magical Mystery Tour, as the film had only six songs. In Britain the soundtrack "album" was released as two singles with three songs apiece. In America, Capitol Records added the Beatles' 1967 singles (including "Penny Lane", "Strawberry Fields Forever", and "All You Need Is Love") to the soundtrack to make a full length album. The revised American version has now become the standard version all around the world; the original British edition of Magical Mystery Tour wasn't released again until the 2012 DVD and Blu-ray special edition rerelease of the movie. Purists don't like the US album because it apparently messes with the band's concept - but the band actually preferred the US album and reissued it as such from the 70s onwards.
  • Megadeth's soundtrack contribution compilation Hidden Treasures was originally designed as a limited edition bonus disc for Youthanasia, but became very popular, largely thanks to the hit single "Angry Again" being included. It was released as a separate release in its own right, and a remastered version was reissued in the UK many years later (the US label kept most of the tracks for the box set Warchest, although some appear in different versions).
  • Oasis had the B-Side compilation "The Masterplan" which was designed for US and Japanese fans to avoid them paying a lot of money for singles. It ended up being released in the UK thanks to demand, and has since become one of their most popular releases.

    Mythology 
  • Although many sources now list among the Norse pantheon a goddess of love named "Astrild", she is in fact the creation of a Romantic-era English poet; the original Norse goddess of love was Freyja.
  • The hippogriff made its first documented appearance in the 16th century poem Orlando Furioso, and it's unlikely that even people who'd sincerely believed in griffins ever gave credence to these horse/griffin hybrids (griffin were supposed to eat horses, not..). That hasn't stopped modern fantasy writers from including them in the roster of commonly-appearing mythical beasts.
  • Rudolph The Red-Nosed Reindeer, created for a department store giveaway childrens' book which was later adapted into a song and a TV special. The character became so popular that he's been added to the eight reindeer from "A Visit From St. Nicholas"/"'Twas The Night Before Christmas" and has become The Face Of The Band in the public consciousness.

    Newspaper Comics 
  • Similar to Clark and Lois' marriage, Jon and Liz of the comic strip Garfield are now the strip's Official Couple after nearly 30 years of non-interest and pity dates on her part. This is mainly because the live action movies had paired the two off in the first and married them in the second.
    • Also, Binky the Clown who debuted in the Garfield Halloween Special before appearing in the strip a year later.
    • Floyd the mouse is an odd case. He debuted as a minor character on Garfield and Friends, and appeared in the strip several years after that show ended, but he only ever appeared in one strip (January 27, 1998).
    • Hubert and Reba, Jon's old neighbors. They first appeared in the special Here Comes Garfield, aired October 25, 1982, then started to appear in the strip 13 days after that.
  • The animated ComicStrip.Peanuts special, Snoopy's Reunion, aired in 1991, featured three of Snoopy's siblings who hadn't appeared in the strip, Andy, Molly, and Rover. While Molly and Rover never appeared in the strip, Andy first appeared in the strip in 1994.
  • Cueball, the villain from the 1946 film Dick Tracy vs. Cueball, would much later (2011) appear in the Dick Tracy comic strip. The main villain from "Dick Tracy vs Gruesome" (1947) would follow suit in 2014. The character's resemblance to Boris Karloff (who played Gruesome in the movie) was played up by having him appear in a production of "Arsenic and Old Lace" and encountering the real Boris Karloff's daughter, Sara, at a horror convention.

    Professional Wrestling 
  • The main character of the '70s manga and anime Tiger Mask, a masked pro wrestler by the same name, was brought into New Japan Pro Wrestling in the '80s. He's since become something of a Legacy Character — at least four different wrestlers have donned the mask — as has his Evil Counterpart, Black Tiger.
  • Suicide, a character who first appeared in TNA Impact!: The Video Game, and later showed up in the ring to exact unspecified revenge on the Motor City Machine Guns. Due to wrestling's self-aware nature, this led the Guns to complain to anybody who'd listen about having been beaten up by a video game character.
  • Tommy Lister, a.k.a. "Zeus", became a pro WWF wrestler after doing No Holds Barred with Hulk Hogan. That venture fared mediocrely, but that didn't stop WCW from bringing him back briefly to fight Hogan as "Z-Gangsta".
    • WCW tried it too, when they made David Arquette the WCW Champion after Ready to Rumble. This isn't quite an example, as Arquette's WCW run was explicitly as himself and not his character from the movie, but it's close enough to merit a mention. The bizarre triple-cage match that serves as the movie's climax also made a WCW appearance as part of this storyline.

    Tabletop Games 
  • Battletech:
    • Adam Steiner was created for the spin-off cartoon; however, he has since been "adopted" into the canon of the main line, becoming one of the heroes of the Lyran Alliance due to his military exploits and eventually becoming known as one of the greatest Archons in the history of the Lyran state. Other characters from the Cartoon have appeared, but none as prominently.
    • Ian Dresari, the protagonist of MechWarrior 4, is canonized in the history of the tabletop game. Word of God is that reports of Ian Dresari's tyranny in the sequel are actually unfounded propaganda by House Steiner to demonize him and turn public opinion from him. Dresari was defeated but ultimately survived the events of Black Knight come the time of the Civil War.
    • The Bombast Laser in Mechwarrior 4: Vengeance was made a canonical weapon eight years later in the "Tactical Operations" advanced rulebook. The Deimos battlemech originally appeared as an unofficial mech in the MekPak Game Mod for the Mercenaries Expansion Pack. It was later made canon and appeared in the official BattleTech technical readouts
    • The various spinoffs often redesign mechs for the sake of aesthetics, some of which make it back into the artwork of the boardgame and the other spinoffs, especially for mechs that haven't had a redesign since 1984 and the days of boxy black-and-white mechs with funny proportions. For example, the trading card game redesigned the awkward looking 'Black Lanner', which later reappeared 9 years later in Mechwarrior Living Legends
  • The Blood Ravens chapter of Space Marines in Warhammer 40,000 were initially invented for the Dawn of War series of video games, but eventually got accepted into 40K canon due to the popularity of the series, and have since appeared in several Black Library novels, including the novelisation of the games themselves.
    • Another was the use of Thunder Hammers without the use of Terminator Armor.
    • Plus being used as an example of how to use Chapter Traits in the old 4th edition Codex (albeit with traits that were not at all representative of the Blood Ravens as seen in-game despite more fitting ones being available, making for a weirdly inverted case of Canon Defilement).
      • The Blood Ravens have also become a one-spin-off-to-another example with the release of the Honour The Chapter sourcebook for Deathwatch. Prior to this there was just one piece of art in Rites of Battle and a quote from Captain Davian Thule in the core book.
    • Another example is the Blood Angels' special character Mephiston, Lord of Death. According to his backstory he used to be Brother Calistarius, the Librarian from the spinoff board game Space Hulk.
  • Elegant Nova of Progression first showed up in Keychain of Creation as an Alchemical Mad Scientist dedicated to making mortals into Alchemical Exalted piece-by-piece. Now, crack open Manual of Exalted Power: Alchemicals and flip through to "Notable Individuals"...
  • The Viashino of Magic: The Gathering were originally introduced in the Tie-In Novel The Prodigal Sorcerer by Mark Sumner. The designers of the game liked them so much that they worked them into the game, and they still turn up from time to time.
  • Gomorra, California, home of the tie-in Collectible Card Game, would eventually become an Immigrant Setting for Deadlands. Part and parcel to this were many, many Canon Immigrants, including most of the entire Whateley Family, Sioux Union, and piratical Maze Rats.
  • Many concepts devised for specialized settings in Dungeons & Dragons have subsequently become incorporated into the core rule system, as when domains and darklords from the 2nd edition Ravenloft setting became a standard feature of the 4th edition Shadowfell.
    • The writers of the Forgotten Realms supplements have made canon a wide variety of plot points from the video games. The whole Bhaalspawn plot from the Baldur's Gate series is referenced in the 3.5E splat Lost Empires of Faerûn. Zehir, the Bigger Bad of Neverwinter Nights 2: Storm of Zehir and the yuan-ti god of poison, was homebrewed for that Expansion Pack, then became one of the primary pantheon of 4th edition and its Nentir Vale setting, and then was relisted as a subservient deity of Bane in the 4E Forgotten Realms Campaign Guide.
  • Psurlons were a new monster created for the Dark Sun: Shattered Lands computer game. They turned out to be popular and interesting enough to be introduced to the tabletop setting as well.

    Theatre 

    Theme Parks 

    Toys 
  • The Starlight Girls (the foster girls Jerrica takes care of) were created specifically for the Jem TV series. However, at least three of them: Ashley, Ba Nee, and Krissie, were later made into dolls.
  • Many of the more notable minor characters in My Little Pony: Friendship Is Magic began gaining more and more recognition and nods from the writers, to the point where several of them were finally firmly cemented into canon in the form of toys. By now, the overwhelming majority of background ponies have toys; previous generations have had toylines that were much bigger than the shows' casts, but Hasbro realized how much fans have latched onto the background characters and have figured that if they make the "extra" toys look like the crowd filler ponies instead of just slapping random color schemes on them, you'll have a character who means something to someone. The Fan Nicknames are even used when not problematic due to copyright.
  • The Baroness actually debuted in Marvel Comics' G.I. Joe in issue #1, created by Larry Hama when he realized there were very few women in G.I. Joe at the time. She was the first character in the canon to cross media, being imported into the TV show and given her own figure thereafter.
  • Monster High's C.A. Cupid is this for Ever After High, where she currently resides.

    Web Comics 
  • In Something*Positive, Fluffmodius, the "little blue freak" that yells "HELLO NEW FRIEND"! at Kharisma, was originally a one-off joke for his non-continuity strips for Rhymes With Witch. Let that be a lesson to you: Do not taunt the Word of God.
    • ...and going the other way, Rippy the Razor was a one-off gag in Something*Positive, but now is Randy's tormentor in some RWW material.
  • The Dini-verse characters Kathy Duquesne, Roxanne Ballentine, and Sonia Alcana from the DC Animated Batwoman movie are regular characters on DC Nation, having been recruited by Hawkman to police his town between incarnations.
  • Somewhere askance of canonical Problem Sleuth, the Midnight Crew, a four-man mercenary group, was created as a donation request that spent most of their time fighting the protagonists. In Homestuck they are exiles in the Trolls' session, and were given about a month of screentime and character development. Later, in the Kids' session, they are given new names, and the leader ascends to Big Bad status.
    • In another Homestuck example, when Andrew Hussie put the Homestuck adventure game up on Kickstarter, he promised humorous rewards for extremely high donations, including "Your fantroll will become canon" for a donation of $10,000. He was incredibly surprised when not one but two people actually donated that amount. True to his word, those trolls (Mierfa Durgas and Nektan Whelan) did show up in the comic's canon... but the $100,000 prize was "Your fantroll will survive past their first panel", so they didn't last long.
  • Season 4 of Survivor: Fan Characters pitted ten canon characters, such as Sephiroth, Riku, Shiki, and Minerva Mink against ten fan-made characters. In other seasons, characters from the fan-characters canon universes visit on the family and friend reward challenge, and the host of all 8 seasons so far has been Jeff Probst.
  • Dragon Ball Multiverse: Even though the authors are not fans of Dragon Ball GT, U18 Bra is clearly the non-fighting, typical teenager GT incarnation. She even wears the same outfit. Word on this is that one of the authors liked her character even though she's from in their minds a bad series.
  • As seen above, Friendship Is Magic 07-P4 has Sunset Shimmer make a brief cameo to help the group see the jewel on the monster they were fighting. The fact that she enters a portal afterwards heavily hints at the fact that this indeed is the Sunset Shimmer of the EqG-verse.

    Web Original 
  • Yelizaveta 'Bounce' from Survival of the Fittest version four started off as a character in the 'In-Universe Chat' (a chatroom where SOTF members could RP being members of the show's audience). After some time, she was brought into the version four pregame as a fully-fledged character.
  • Lastie's PRIMARCHS has Farseer Kyli, a character who was originally created to MST the story. Lastie featured her in the story's 3rd arc.
  • Barry Kramer, originally the editor for JonTron, has officially transferred over full-time to Game Grumps, which no longer includes Jon.

    Western Animation 
  • The Animated Adaptation of Anne of Green Gables features the characters of Felicity, Felix, & Hetty King as well as suspected witch Peg Bowen, all of whom originally appeared in the live-action series Road to Avonlea (known just as "Avonlea" when it aired in the US on Disney Channel). Though Sullivan Productions created both shows, so they're only reusing characters they created.
  • The antagonists from both live action Ben 10 films have appeared in Ben 10: Ultimate Alien. In that sense, Nanomech is one too.
  • Matilda and Sergeant Slipper were created for the animated adaptation of Dennis the Menace (UK). They both made appearances later in The Beano.
  • On The Fairly OddParents, two of the Crimson Chin's villains, the Iron Lung and the Brass Knuckles, appeared in the non-canon webtoons before appearing in the series proper.
  • Though The Goliath Chronicles has been excised from Gargoyles canon, with the exception of season premiere "The Journey", another part of the series has managed to find its way into fanon and eventually canon: The scene where Hudson's blind Human friend Robbins reveals that he already figured out Hudson was a Gargoyle, particularly the part where he mentions a scent "like old leather and concrete".
    • While the comic licensed by Marvel was deemed noncanon, Petros Xanatos appeared in #7 prior to his onscreen appearance in Vows.
  • Disney's Max Goof was imported into the Disney canon from Goof Troop. This is unique in that Max has no "iconic" depiction to revert to and, unlike other characters, has aged appreciably over time. However, Max's appearance and role is arguably based on Goofy Jr., a character used in Goofy's original cartoon shorts (he once introduced himself as "Goofy Jr., ma'am").
  • King Louie of Disney's The Jungle Book has appeared in a few other works based on the stories that the Disney film is based on, most notably Fables, which, as an afterthought, the creator Bill Willingham described as, "a very good example on why it's best to go back to the source material before one embarks on a major story, rather than rely on often faulty memory of which characters were original canon and which weren't."
  • Lola Bunny. Created for Space Jam, she became a regular in Baby Looney Tunes, the comic series, and most recently The Looney Tunes Show.
    • Before Lola, there was Honey Bunny, Bugs's girlfriend in the comics, who made a cameo appearance in the TV special "Bugs Bunny's Thanksgiving Diet".
  • Disney doesn't treat direct-to-video sequels as canon. The Lion King II: Simba's Pride is about Simba's daughter Kiara. Kiara has been accepted by most of the fandom however it wasn't until The Lion Guard that she reappeared in a media.
  • The character of Brutus from Popeye is an odd twist on the trope. The original Thimble Theater Newspaper Comics used the character Bluto first. After a two week fight with Popeye in the comics, Fleischer Studios thought he would be a good character to include in their theatrical cartoon shorts. Thinking (mistakenly) that Bluto was a creation of Fleischer Studios, Segar's successors created a Captain Ersatz of Segar's own character, named Brutus. Later in the Hanna-Barbara cartoons, Bluto was replaced with Brutus, the canon immigrant from the comics, who looked identical but had a different name, thus confusing children everywhere.
  • As pointed out on its' main page, The Hex Girls from Scooby-Doo! and the Witch's Ghost could technically count, since they debuted in that movie, and have since gone on to appear in another movie, an episode of What's New, Scooby-Doo? and 2 episodes of Scooby-Doo! Mystery Incorporated.
  • Arguably Disney's best example; while Donald and Daisy Duck premiered in Disney animated shorts, one of Duckburg's most illustrious citizens, Scrooge McDuck, started as a supporting character in the Carl Barks' Donald Duck comics in 1947, where he grew in popularity until he wound up getting his own title in the fifties. His first animated appearance was in an educational short called "Scrooge McDuck and Money" in 1967, and then he starred in the 1983 theatrical featurette Mickey's Christmas Carol, as Ebenezer Scrooge. He then co-starred with Goofy in "Sport Goofy in Soccermania" before starring in DuckTales, cementing his place as one of the most famous cartoon ducks of all time.
    • Meanwhile, Donald's nephews, Huey, Dewey, and Louie, first showed up in the Silly Symphonies comic strip (which Donald starred in at the time). Their first appearance was later adapted into an animated short, and the rest is history.
  • In the Shaun the Sheep movie, the pigs can be seen watching Morph on TV. In the new Morph series, a Wallace & Gromit pencil can be seen.
  • According to Matt Groening, Milhouse Van Houten made his first appearance in a The Simpsons Butterfinger commercial.
    • German exchange student Uter Zorker also debuted in the non-canon episode Treehouse of Horror IV. However, he didn't prove popular with viewers and was removed from the show one season later in The PTA Disbands!.
  • A few elements of the 4Kids Teenage Mutant Ninja Turtles have made their way into the original comic book universe, including the Battle Nexus, and its proctor, the Gyoji; and more recently, Hun and (off-panel only, due to the series' cancellation) Agent Bishop.
  • In the Tom and Jerry cartoons, the grey mouse who could speak came from the licensed comics. There, he was called Tuffy, and was Jerry's friend; when he was adapted, he became Nibbles, and Jerry's nephew.
  • The character Oil Slick was originally a toy-only character in the Transformers Animated series. However, the writers found the idea of a chemical warfare expert who turned into a motorbike with a ram's head on the front (and a ninja, to boot) rather appealing, and he was later written into both the supplementary comic series and the show itself as part of Team Chaar.
    • The Lockdown figure from the Transformers: Revenge of the Fallen toyline was later repurposed as G1 Lockdown. Although they're completely separate characters, their toys are identical and with only small differences in canonical appearances.
    • And now, Lockdown appears in Age of Extinction! He looks quite different from the RotF toy, though. (And yes, TF toys usually come before the movie/cartoon/comic they're designed for, but Lockdown's toy came out when AoE couldn't possibly have been planned, years ago; it was more like "Everybody loved that Lockdown guy, let's movie-ify him and see if they'll buy his toy twice!"
  • Woody Woodpecker has two: His niece and nephew Knothead and Splinter originally appeared in the comics, but were eventually brought over into his theatrical toons.
  • The former law enforcer-turned-criminal Gorvan was an original character created for a videogame adaptation of Ben 10: Alien Force. Said character finally made its first canon appearance in Ben 10: Omniverse and it was implied that his backstory still involved betraying the Plumbers.
