[[caption-width-right:350:Sam Carter is a force to be reckoned with in [[Series/StargateSG1 both]] [[Series/StargateAtlantis galaxies]].]]

When a character leaves one show to join the cast of another (often because the original show has ended). Basically a permanent {{crossover}}.

Sometimes a character's SpinOff gets canned. When this happens, they'll often transplant back to their show of origin, with some [[HandWave flimsy explanation]]; if this happens, the chances of a FullyAbsorbedFinale go way up. Also, a LateSpinOffTransplant occurs when a character doesn't move to a spinoff until some time later. See also RoguesGalleryTransplant, a more specific variant of this trope where a villain from a superhero's RoguesGallery shifts to fighting someone else. Compare CanonImmigrant and CanonWelding. Not to be confused with the wiki operation that is also called a Administrivia/TropeTransplant.

Unrelated to BillyNeedsAnOrgan and WalkingTransplant, which are about biological transplants.

Not to be confused with the ska punk SuperGroup, Transplants.

[[folder:Anime & Manga]]
* Katori Matou from ''Manga/RomanClub'' joins ''Manga/{{Amanchu}}'' as scuba club advisor and Hikari's homeroom teacher.
* Creator/{{CLAMP}}:
** Manga example: Subaru from ''Manga/TokyoBabylon'' becoming part of the cast of ''Manga/{{X1999}}''. His ArchEnemy, Sakurazuka Seishirou, joins the cast as his opposite while his twin sister makes cameos.
** Grown-up versions of the heroes from ''Manga/ClampSchoolDetectives'' also appear in ''Manga/{{X1999}}'', as part of the AncientTradition supporting the heroes.
* Arama-san originated in ''Helvetica Standard'' by [[Manga/{{Nichijou}} Keiichi Arawi]], before returning as a recurring character in Arawi's 2016 ''Manga/{{CITY}}'' manga. The famous mangaka "Daisuke Naganohara", aka [[spoiler:Mio]], also returns as a consistent presence in one character's subplot.
* ''Manga/MyHeroAcademia'':
** In Chapter 47, Momo and Kendo got internships under Snake Heroine Uwabami. Her name and design is lifted straight from Uwabami from ''Manga/OumagadokiDoubutsuen'', one of the author's previous works. In ''Academia'''s universe, she is a human with superpowers rather than a snake with a human form. Other characters make cameos (Shishido and Toytoy to name a few), presumably running on the same principle as Uwabami.
** Chapter 87 takes it a step further by introducing Gang Orca, who's more or less literally [[spoiler:a post HeelFaceTurn]] Sakamata.
** The arcade game introduces three ''Oumagadoki'' transplants under the team name "Wild Villains": Curator ([[spoiler:pre-HeelFaceTurn]] Isana), Bearhead (Shikuma), and Zookeeper (a brainwashed Hana).
** As an act of ''internal'' transplant, Snipe (one of the U.A. Faculty) was one of the main characters from the ''Manga/{{My Hero|2008}}'' oneshot that spawned the series.
* After ''Manga/NegimaMagisterNegiMagi'' ended, Evangeline, who now goes by Yukihime, moved on to the StealthSequel series ''Manga/UQHolder''. Later on, Fate, one of the primary antagonists of ''Negima'' and other characters like Mana also show up. [[spoiler:This gets played with a bit as it's later revealed ''UQ Holder'' is an AlternateTimeline from the main ''Negima'' series where events played out differently.]]
* The underground boss of the resort planet Haccone in ''Anime/RobiHachi'' is Wombat from ''Anime/CuteHighEarthDefenseClubLove'', the previous ''Cute High'' series Creator/StudioComet did before this.
* Tamate of ''Manga/SlowStart'' is basically a grown-up version of ''Manga/BottleFairy''[==]'s Tama-chan, from name, looks, [[{{Otaku}} hobbies]], [[GenkiGirl temperment]], to clothing preferences. Yuiko Tokumi, who drew these two series approximately 10 years apart, [[WordOfGod stated]] she'd like people seeing the two as [[https://twitter.com/1093yuiko/status/740486673843245060 "infinitely similar entities"]].
* In ''[[Manga/StraightenUpWelcomeToShikaHighsCompetitiveDanceClub Straighten Up!]]'' two of the supporting characters are Michiru Kosei, the supervisor for the Dancesport Club, and her husband Tatsuya. Both previously appeared as high school students and two of the main characters in ''Koganeiro'', a short story that Takuma Yokota had published in Magazine/ShonenJump years earlier. After ''Straighten Up!'' ended, Tatsuya shows up as the coach of the main soccer team in the author's next series ''Shudan!'' having been previously established as a youth soccer coach in ''Straighten Up!''
* Kaneda, one of the teachers in ''Manga/WanderingSon'', was a character in ''Shiki no Juunin''. The anime adaptation [[MythologyGag references this]] by showing Kaneda meeting a green haired man and a woman (the protagonists of the previous manga) in the final episode.
* Meito "Anime Tenchou" Anisawa, the HotBlooded store owner in ''Manga/LuckyStar'''s anime adaptation, isn't from the manga nor is he original to the anime; he actually predates ''Lucky Star'' as a whole, being created as the mascot for the Animate store chain several years before.

[[folder:Comic Books]]
* ''Franchise/TheDCU'':
** The entire roster of Quality, Fawcett, and Creator/CharltonComics superheroes were transplanted into the DC Universe after DC bought them out. At first they were included as their own separate realities in TheMultiverse, before being integrated into the single MergedReality of the DCU after ''ComicBook/CrisisOnInfiniteEarths''.
*** A few decades later, the heroes of Creator/MilestoneComics did the same thing.
*** And then the Archie/Red Circle superheroes and ComicBook/THUNDERAgents.
*** With the ComicBook/New52 reboot, characters from Creator/{{Wildstorm}} were also integrated into the main DCU (where they had previously existed in the separate reality of Earth-50).
** Charity, the onetime HorrorHost of 70s DC "Weird" horror title ''Forbidden Tales Of Dark Mansion'', later shows up in the 1990s ''ComicBook/{{Starman}}'' series.
** Maggie Sawyer first appeared in ComicBook/{{Superman}}'s comics as one of Metropolis' cops. Of course, ask any reader what they know about her, and they'll most likely say she's ComicBook/{{Batwoman}}'s girlfriend. That's because, at the beginning of the ComicBook/New52, Batwoman's previous love interest Renee Montoya was RetGone, so they had Maggie transfer from Metropolis to Gotham. And after ''ComicBook/BatmanEternal'', Maggie became '''Commissioner''' Sawyer. Maggie was later made somewhat redundant when Renee was finally brought back into continuity, and as of ComicBook/DCRebirth, she's been PutOnABus back to the ''Superman'' books, where she's once again a Metropolis police officer.
** Maxwell Lord, originally a supporting character in ''ComicBook/JusticeLeagueInternational'', was turned into a villain for ''ComicBook/InfiniteCrisis''. Despite the unpopular decision, especially because it was a blatant retcon, the decision has stuck and he has since been turned into a ''Justice League'' villain. However, because he was infamously killed by Wonder Woman, he's also been transplanted into a villain for her ''specifically'', in both Mariko Tamaki's ''Wonder Woman'' run and ''Film/WonderWoman1984''.
* Many of Creator/GarthEnnis' characters and concepts end up in another of his comics, even when they are in officially different universes. ''ComicBook/TheBoys'' has Billy Butcher mentioning spacker porn (a term coined by Spacker Dave in ''ComicBook/ThePunisherWelcomeBackFrank'') and Cassidy from ''ComicBook/{{Preacher}}'' tending bar, Kathryn O'Brien in ''ComicBook/ThePunisherMAX'' is strongly implied to be the same person as Kathryn [=McAllister=] from ''ComicBook/{{Hitman|1993}}'', etc.
* ''Franchise/MarvelUniverse'':
** A lot of [[Characters/MarvelComicsDeadpool Deadpool]]'s supporting cast and enemies are obscure characters who were carried over with Deadpool when he made the jump to being a standalone character rather than merely a supporting ''ComicBook/XMen'' character. Characters/{{Domino|Marvel Comics}}, [[Characters/MarvelComicsTaskmaster Taskmaster]], ZERO, Dr. Bong, Sandi Brandenberg, Outlaw, and Deuce the Devil-Dog are just a few examples. [[Characters/MarvelComicsCable Cable]], while not fully transplanted from the X-Men, is more often remembered for his partnership with Deadpool than any of his other escapades.
** [[Characters/MarvelComicsMaryJaneWatson Mary Jane Watson]], one of the most famous supporting character of ''ComicBook/SpiderMan'', became a main character in the 2015 ''ComicBook/InvincibleIronMan2015'' run replacing Pepper Potts role as new Tony's personal assistant. The same run saw [[Characters/MarvelComicsDoctorDoom Doctor Doom]] join the cast, as this was during the period when ''Fantastic Four'' [[ExiledFromContinuity was no longer being published due to an embargo over movie rights]].
** Betsy Braddock was first introduced in ''ComicBook/CaptainBritainWeekly'', but after a decade as a supporting character she joined the X-Men and took the codename [[Characters/MarvelComicsPsylocke Psylocke]].
** In a reverse of the above, [[Characters/MarvelComicsKittyPryde Shadowcat]] and [[Characters/MarvelComicsNightcrawler Nightcrawler]] were absent during the X-Men's ''ComicBook/TheFallOfTheMutants'' storyline (in which the main team died on international television, but were resurrected offscreen). Chris Claremont used this as an opportunity to team them up with ComicBook/CaptainBritain, creating the team series ''ComicBook/{{Excalibur|MarvelComics}}''.
** A few years after the cancellation of ''ComicBook/AlphaFlight'' and his mini-series, Northstar joined the main X-Men team in Creator/ChuckAusten's run on ''[[ComicBook/UncannyXMenChuckAusten Uncanny X-Men]]''.
** Goldballs, a character from Creator/BrianMichaelBendis' ''ComicBook/UncannyXMen'' run, was brought over into [[Characters/MarvelComicsMilesMorales Miles Morales]]'s supporting cast after Miles was brought over into the mainstream Marvel universe post Secret Wars.
** Several times, the ComicBook/XMen would travel over and join ComicBook/TheAvengers.
*** The first and most notable were [[Characters/MarvelComicsQuicksilver Quicksilver]] and Characters/ScarletWitch, who after defecting from the Brotherhood of Evil Mutants became a part of the Avengers' second major team line-up (also known as "ComicBook/CapsKookyQuartet").
*** After gaining his blue-furred form in ''Amazing Adventures'' #11, former X-Man Hank [=McCoy=], AKA [[Characters/MarvelComicsBeast Beast]], was recruited to join the Avengers, before leaving to rejoin the original five X-Men as X-Factor.
*** [[Characters/MarvelComicsLogan Wolverine]] was a core member of the team during [[ComicBook/NewAvengers the Bendis run]]. [[Characters/MarvelComicsStorm Storm]] was also an Avenger briefly (as she was married to ComicBook/BlackPanther at the time), but left during ''ComicBook/AvengersVsXMen''.
*** Former ComicBook/NewMutants Cannonball and [[Characters/MarvelComicsSunspot Sunspot]] were recruited to join ComicBook/TheAvengersJonathanHickman. Sunspot prospered so well in his new team, he later bought the supervillain team AIM and rebranded it as Avengers Idea Mechanics, leading his own teams in ''ComicBook/NewAvengers2015'' and ''ComicBook/USAvengers''.
*** Havok, Sunfire, [[Characters/MarvelComicsRogue Rogue]], and [[Characters/MarvelComicsCable Cable]] were all members of the ''ComicBook/UncannyAvengers'', an Avengers SpinOff team dedicated to co-species cooperation.
*** In an inversion, [[ComicBook/SubMariner Namor]], primarily known for his ties to the Avengers, ComicBook/{{The Invaders|MarvelComics}} and the ComicBook/FantasticFour, joined the X-Men during the Utopia era.
*** Not an Avengers team per se, but the 2016 ''ComicBook/{{Champions|2016}}'' relaunch saw [[Characters/MarvelComicsCyclops Cyclops]] as part of the team, fighting alongside other Marvel heroes like [[Characters/MarvelComicsMilesMorales Miles Morales]], [[Characters/MarvelComicsKamalaKhan Kamala Khan]] and [[ComicBook/TotallyAwesomeHulk Amadeus Cho]]. Note that this is something of a tradition, as the original 70s ''ComicBook/{{Champions|1975}}'' run featured [[Characters/MarvelComicsIceman Iceman]] and [[Characters/MarvelComicsAngel Angel]] (who had recently been [[PutOnABus written out of]] ''X-Men'' by Creator/ChrisClaremont) as main characters.
** Relatedly, all four members of the ComicBook/FantasticFour have been Avengers at one point or another, usually during periods where they were taking a break from their original team (or, in the case of the Human Torch, when the FF disbanded after ''ComicBook/SecretWars2015'').
** Beast of the X-Men and the Human Torch also both worked alongside the Inhumans in ''[[ComicBook/InhumansCharlesSoule Uncanny Inhumans]]''.
** While that was happening, Characters/TheThing joined the ''[[ComicBook/GuardiansOfTheGalaxy All-New Guardians of the Galaxy]]'' alongside [[Characters/MarvelComicsKittyPryde Shadowcat]] and [[Characters/MarvelComicsFlashThompson Agent Venom]] during a time when Star-Lord and Gamora were absent (Kitty even taking the Star-Lord mantle herself, as she was engaged to Peter Quill at the time).
** ''ComicBook/UltimateMarvel'':
*** At the end of ''Ultimate Power'', an IntercontinuityCrossover between Ultimate universe and the ''ComicBook/SupremePower'' universe, Zarda and ComicBook/NickFury switched places. The latter was a major character in the post-TimeSkip new ''Supreme Power'' series, while the former had some DestructoNookie with the Hulk. After ''ComicBook/{{Ultimatum}}'', Nick Fury crossed back over.
*** ''ComicBook/UltimateSpiderMan'' also had its share of transplanting. First Kitty Pryde left the X-Men and became Peter's girlfriend for a while, and then they returned the favor when this universe's Liz Allan was revealed as a mutant and went to train at Xavier's. ''ComicBook/UltimateFantasticFour'' and ''ComicBook/UltimateXMen'' were cancelled after ''ComicBook/{{Ultimatum}}'', so Johnny Storm and Iceman were moved into the Parkers' house.
*** Quicksilver and the Scarlet Witch started as villains in ''ComicBook/UltimateXMen'', and then moved to ComicBook/TheUltimates. It was a complex MythologyGag of the thing that happened in the main universe, but it is an example on its own right nonetheless.
* Creator/PeterDavid's ComicBook/SachsAndViolens, of the mini-series of the same name, were transplanted ten years later to ''ComicBook/{{Fallen Angel|2003}}''.
* ''ComicBook/TheSandman1989'': The series contains a number of horror host transplants: Cain and Abel are the most famous, but also Eve, the Three Witches, Destiny, Lucien and The Mad Mod Witch.
* ''ComicBook/{{Teenage Mutant Ninja Turtles|Mirage}}'': The Fugitoid was originally introduced in his own stories from Mirage Comics before the Turtles even made their debut. After their success, [[CanonWelding he was eventually included]] in the TMNT comics.
* When Creator/MarvelUK was publishing officially licensed ''Franchise/{{Transformers}}'' comics and ''Magazine/DoctorWhoMagazine'' as well as Marvel Universe comics, the character ComicBook/DeathsHead, who originated in the ''Transformers'' continuity, was transferred into the Marvel Universe via an encounter with the Seventh Doctor in the ''DWM'' comic strip. (The middle installment explains why he shrinks from Transformer HumongousMecha size to humanoid size -- the Doctor shot him with one of the Master's Tissue Compression Eliminators, a lethal ShrinkRay that the Master used as his weapon to turn people into doll-sized corpses in old-school Doctor Who. Death's Head was badass enough that the "eliminating" didn't take, but enough 'tissue compression' took place that he's now the size of the characters he'd now be interacting with.)

[[folder:Fan Works]]
* In a ''WebAnimation/HomestarRunner'' fan series called "The Homestar Runner Show", Weena from ''Literature/TheTimeMachine'' is a regular character, even having some cartoons where she is the main character! Being in the ''Homestar Runner'' world now, she even [[InvisibleAnatomy lacks visible arms]] as well!
* Despite appearing only in ''VideoGame/DragonAgeII'', [[spoiler:Bethany Hawke]] ends up becoming a member of the [[VideoGame/DragonAgeInquisition Inquisition]] in the ''Fanfic/TwiceUponAnAge'' series.
* {{Discussed|Trope}} in [[http://waitingforthet.tumblr.com/post/166530274163/fun-fact-nightcrawler-was-originally-designed-to this]] ''ComicBook/XMen''[=/=]Creator/MarvelComics fan comic.

[[folder:Literature]]
* Creator/LFrankBaum wanted to move away from the [[Literature/LandOfOz Oz books]] and tried to start a new series with a new little girl protagonist, Trot. This series didn't do as well, and Trot ended up moving to Oz (in ''The Scarecrow of Oz'') and being immediately DemotedToExtra there.
* Granny Weatherwax and Nanny Ogg are the primary main characters of Literature/{{Discworld}}'s 'Witches' sub-series. However, later on Terry Pratchett decided to "retire" them, and they now tend to only make cameos in other books, namely as mentors to Tiffany Aching, [[Literature/TheWeeFreeMen who has her own series]].
* Jas, the WingedHumanoid from the ''TabletopGame/{{Spelljammer}}'' comics by Jeff Grubb and Kate Novak, later joined Finder's Band in the same authors' ''TabletopGame/ForgottenRealms'' novels.
[[/folder]]

[[folder:Live-Action TV]]
* Years after the cancellation of ''Series/AgentCarter'', Creator/EnverGjokaj's Daniel Sousa joined ''Series/AgentsOfSHIELD'' as a RecurringCharacter for its final season.
* ''Series/{{Angel}}'':
** In the latter half of the first season, all three main characters were Transplants from ''Series/BuffyTheVampireSlayer'': Angel, Cordelia Chase, and Wesley Wyndam-Pryce. It could have gone even further, as Doyle, the only non-Transplant lead on the show, was originally going to be the ''Buffy'' character Whistler before that plan fell through.
** In the fifth season -- after ''Buffy'' had ended -- Spike and later Harmony (who both originated on ''Buffy'' and and guest starred on ''Angel'') were both Transplanted and made regulars as well.
* ''Series/{{Arrowverse}}'':
** The Arrowverse's third series titled ''Series/LegendsOfTomorrow'' features characters from its first two shows (''Series/{{Arrow}}'' and ''Series/TheFlash2014'') as main characters, specifically: Sara Lance/White Canary, Ray Palmer/The Atom, Martin Stein/[[FusionDance One Half]] of Firestorm, Leonard Snart/Captain Cold and Mick Rory/Heat Wave, followed by Wally West/Kid Flash in its third season.
** The Legion of Doom in Season 2 of ''Legends'' is made up of transplants from ''Arrow'' and ''The Flash'': Eobard Thawne, Damien Darhk, Malcolm Merlyn, [[spoiler:Leonard Snart]]. Darhk later comes back to be a villain in Season 3, along with his daughter Nora.
** Mari's sister Kuasa is resurrected and transplanted from ''WesternAnimation/{{Vixen}}'' to ''Legends''.
** After the cancellation of [[Characters/{{Hellblazer}} John Constantine]]'s [[Series/{{Constantine}} own series]], he showed up the following year for a guest spot on ''Arrow'', and was then eventually added to the cast of ''Legends of Tomorrow.''
** Earth-2 Laurel Lance was originally TheDragon of ''The Flash'' Season 2 BigBad Hunter Zolomon/Zoom before moving to ''Arrow'' to become the Black Canary of her home universe following her eventual HeelFaceTurn.
** Clark Kent/Superman went from a RecurringCharacter and HeroOfAnotherStory in ''Series/Supergirl2015'' to headlining [[Series/SupermanAndLois his own show along with his wife]]. Two characters there, Sam Lane and Morgan Edge, were also recurring characters on the same show [[TheOtherDarrin but are now played by different actors]].
* The short-lived Creator/StevenBochco legal drama ''Civil Wars'' introduced two characters, Eli Levinson (Alan Rosenberg) and Denise Ianello (Debi Mazar), who, for whatever reason, found themselves as regular characters on ''Series/LALaw'' after the cancellation of their series.
* Following the cancellation of ''Series/CriminalMindsBeyondBorders'', Daniel Henney's character Matt Simmons to the parent show ''Series/CriminalMinds'', filling the role left from the departure of Damon Gupton.
* With the cancellation of the original ''Series/{{CSI}}'' series, in addition to getting a TV movie to wrap the original show up it was also announced that D.B. Russell would be moved over to spinoff ''Series/CSICyber''.
* Mrs. Edna Garrett, the housekeeper from ''Series/DiffrentStrokes'', went on to become the house mother for the girls in ''Series/TheFactsOfLife'', although ''Diff'rent Strokes'' continued to run in the meantime.
* Helen [=DuBois=] went from Josh's boss on ''Series/DrakeAndJosh'' to the principal of Hollywood Arts in ''Series/{{Victorious}}''.
* Deputy Enos Strait returned to ''Series/TheDukesOfHazzard'' when his Atlanta-based spinoff ended after one season.
* Senator Edward Sheffield, played by Dean Stockwell, first appeared in the short-lived Creator/DonaldPBellisario produced U.S. Supreme Court series ''Series/FirstMonday'' before he went over to ''Series/{{JAG}}'' and became the Secretary of the Navy.
* ''Series/GeneralHospital'':
** The popular couple of Kevin and Lucy was transplanted to to ''GH''-spinoff ''Port Charles'' to attract ''GH''[='s=] fanbase and anchor the new show to its parent show. When ''Port Charles'' was canceled six years later, Kevin and Lucy were nowhere to be found on the parent show despite maintaining plausible ties to the canvas. Then again, considering by that time ''GH'' was becoming a daytime romance novel version of ''Series/TheSopranos'' and ''PC'' had become a daytime romance novel version of ''Series/BuffyTheVampireSlayer'' with Lucy being revealed as a slayer and half the doctors (including one or two ''GH''-legacy characters) becoming vampires, reintegrating the characters would have been tricky to say the least.
** On the other hand, it was easier to transplant just about every character in the prime time spinoff ''Night Shift'' back to the mothership when it ended.
*** Some of them had never left ''GH'' in the first place; they were pulling double duty.
* After ''Series/TheGoldenGirls'' (and subsequently ''The Golden Palace'') ended, Sophia joined ''Series/EmptyNest''.
* ''Series/GreysAnatomy'':
** Addison Montgomery left ''Grey's Anatomy'' to helm her own spinoff, ''Series/PrivatePractice''. A few seasons later the show introduced Amelia Shepherd, who was the sister of ''Grey's'' lead Derek. Amelia guested in several ''Grey's'' episodes during both show's runs, and joined the cast full-time after ''Private Practice'' ended.
** Ben Warren left ''Grey's'' to join the Seattle Fire Department in ''Series/Station19''. Later Carina [=DeLuca=], who had been recurring on ''Grey's'' for several years, began dating Maya Bishop from ''Station 19'' and became a regular there - though in an interesting case, she's still a doctor at Grey Sloan Memorial Hospital despite not appearing nearly as often on the hospital's show.
* After the cancellation of ''Series/SamAndCat'', the secondary comic relief character [[DumbMuscle Goomer]] would make the jump to ''Series/HenryDanger'' (and the later ''Series/DangerForce'' spin-off), where he became the [[MinionWithAnFInEvil bumbling minion]] to recurring villain Frankini (who himself is all but stated to be Cat's [[UnseenNoMore unseen brother]] from ''Series/{{Victorious}}'').
* Florence returned to ''Series/TheJeffersons'' after her spinoff died a quick death.
* ''Series/JoanieLovesChachi'''s title characters returned to ''Series/HappyDays''.
* ''Franchise/LawAndOrder'':
** [[JustForFun/JohnMunch Detective Munch]] joined the cast of ''Series/LawAndOrderSpecialVictimsUnit'' after ''Series/HomicideLifeOnTheStreet'' went off the air. ''SVU'' has another character, Captain Cragen, from the early seasons of [[Series/LawAndOrder the parent series]]. Peter Stone, [[RetCon estranged]] [[SpinOffspring son]] of the parent series' Ben Stone, moved from ''Series/ChicagoJustice'' to ''SVU'' in its 19th season after his original show flopped.
** Det. Lennie Briscoe went from the parent series to ''Series/LawAndOrderTrialByJury'', though only a few episodes were filmed with him prior to actor Creator/JerryOrbach's death.
** Det. Mike Logan went from the parent series to ''Series/LawAndOrderCriminalIntent'' (after a telemovie).
** Original ''SVU'' co-lead Det. Elliot Stabler went on to headline ''Series/LawAndOrderOrganizedCrime''.
* In ''Series/{{Legacies}}'', we have Alaric Saltzman from ''Series/TheVampireDiaries'' and Hope Mikaelson from ''Series/TheOriginals''.
* ''Series/TheLoneGunmen'' was a short-lived spin-off of ''Series/TheXFiles''. The eponymous character returned for [[FullyAbsorbedFinale one episode of the parent show]]. [[spoiler:In which [[BackForTheDead they die]] [[HeroicSacrifice heroically]]. However, Chris Carter has said that nobody really dies for good in that verse...]]
* John Irvin started on ''Series/NYPDBlue'', was transplanted to ''Series/PublicMorals'' and when that series ended transplanted back onto ''NYPD Blue''.
* After the cancellation of ''Series/OnceUponATimeInWonderland'', Creator/MichaelSocha's character Will Scarlet was moved to the show's [[Series/OnceUponATime parent series]] for its fourth season. However, the writers were never sure what to do with him and any plots he may have brought with him never panned out, leading to him vanishing by the end of the season.
* ''Series/PowerRangersLostGalaxy'' had [[RobotBuddy Alpha 6]], Bulk, Professor Phenomenus, and Karone as transplants from the "Zordon Era" of the ''Franchise/PowerRangers'' timeline, as ''Lost Galaxy'' onwards would adapt ''Franchise/SuperSentai'''s "standalone seasons" method.
* When the first of the two ''Series/SavedByTheBell'' spinoffs, ''The College Years'', ended, Screech was moved over to the other spinoff, ''The New Class'', for the remainder of that show's run.
* ''Franchise/StargateVerse'':
** A relatively unimportant and yet much-beloved recurring character on ''Series/StargateSG1'', Dr. Rodney [=McKay=], crossed over to ''Series/StargateAtlantis''. Oddly enough, this wasn't planned: the same actor auditioned for the part of "Doctor Benjamin Ingram", and he impressed the creators such that they decided to rewrite Ingram as [=McKay=].
** While less prominent in both shows, Major Lorne also appeared in a few episodes of ''SG-1'' before permanently relocating to Atlantis.
** Followed by Samantha Carter after ''SG-1'' was cancelled. Creator/AmandaTapping was contracted for the never-produced Season 11 of ''SG-1'', so they brought her character to star in ''Atlantis'' for one season instead. After being in turn replaced as the leader of the Atlantis Expedition by [[ObstructiveBureaucrat IOA]] agent Richard Woolsey (yet ''another'' transplant from ''SG-1'' who had recurring appearances in ''Atlantis'' before), Carter had a guest appearance in the GrandFinale, "Enemy at the Gate". She wasn't intended to only be in one season, but Amanda Tapping wanted to leave to pursue ''Series/{{Sanctuary}}'' so they had to replace her.
** O'Neill was transplanted to ''Series/StargateUniverse''.
* ''Franchise/StarTrek'':
** Chief Miles O'Brien was a main character on ''Series/StarTrekDeepSpaceNine'', having originated as a recurring character on ''Series/StarTrekTheNextGeneration''. Later, ''TNG'' main character Worf was brought onto the main cast in the fourth season of ''Deep Space Nine'' following the conclusion of ''TNG'' and release of TheMovie, ''Film/StarTrekGenerations''. (Worf would show up back on the ''Enterprise'' for later ''TNG'' films: ''Film/StarTrekFirstContact'' had a good {{Watsonian|VersusDoylist}} excuse; ''Film/StarTrekInsurrection'' provided a bit of a HandWave; ''Film/StarTrekNemesis'' didn't even bother.)
** They attempted to transplant ''TNG'' recurring character Ensign Ro Laren to a spinoff series ''twice'', but each time actress Creator/MichelleForbes refused due to reluctance to be tied to a six-year contract. Each time, the role was reworked into an original character: for ''Deep Space Nine'' it became Major Kira Nerys (Creator/NanaVisitor), and for ''Series/StarTrekVoyager'' it became Lieutenant B'Elanna Torres (Creator/RoxannDawson).
** This almost happened in ''Voyager'', with ''TNG'' one-shot character Nick Locarno (Creator/RobertDuncanMcneill) from "The First Duty" intended to be brought back as a main character. What happened next is muddled: some staff claimed they changed course due to Locarno being BeyondRedemption ([=TL;DR=] GlorySeeker, got a cadet killed; DeceasedFallGuyGambit; RevealingCoverup; kicked out of the Academy), while others claimed that bringing back the character would mean [[MoneyDearBoy paying royalties to "The First Duty"'s writer for seven years]]. Regardless, the result was a SuspiciouslySimilarSubstitute named Tom Paris, played by Robert Duncan [=McNeill=].
*** The same thing probably happened with Taurik, a Vulcan engineer who was the focus of [[LowerDeckEpisode one episode]] of ''Series/StarTrekTheNextGeneration''. The same actor later played a recurring Vulcan engineer named Vorik on ''Voyager''.
** ''[[Series/StarTrekTheNextGeneration Enterprise-D]]'' crewman Reginald Barclay also popped up on ''Series/StarTrekVoyager,'' actually making ''exactly'' the same number of appearances in both series.
** And, of course, Jim Kirk, who debuted in ''Series/StarTrekTheOriginalSeries'' (1963–1966) played by Creator/WilliamShatner, showed up in ''Series/StarTrekStrangeNewWorlds'' (2022–) played by Creator/PaulWesley.
* Nostalgiaferatoo, a boring vampire was introduced in 2022 as a recurring character on Creator/MeTV's ''Series/ToonInWithMe'' played by host Bill Leff. In 2023, the character has made more appearances on fellow [=MeTV=] and Chicago based series ''Series/{{Svengoolie}}'' as part of the Sven Squad.
* E.L. "Tenspeed" Turner of 1980's ''Series/TenspeedAndBrownShoe'' turned up in 1987 as a supporting character on ''Series/JJStarbuck''.
[[/folder]]

[[folder:Newspaper Comics]]
* ComicStrip/LittleOrphanAnnie had her strip end with a serious {{Cliffhanger}}, which was resolved in a FullyAbsorbedFinale in ''ComicStrip/DickTracy''. She then joined the latter series as a recurring character.
* Patina Welding originated in the comic ''ComicStrip/OnTheFastrack'' as the main character's daughter, but occasionally cameoed in the SharedUniverse comic ''ComicStrip/SafeHavens''. She eventually made the full transition to Transplant when she decided to go to college at Havens University, where main character of Safe Havens (and former babysitter) Samantha works at.
[[/folder]]

[[folder:Toys]]
* ''WesternAnimation/GIJoeExtreme'' featured Sgt. Savage from its very short-lived predecessor ''WesternAnimation/SgtSavageAndHisScreamingEagles'' as one of the Joes.
* ''Toys/MyScene'' is a ''Franchise/{{Barbie}}'' spin-off that originally featured Barbie. Barbie was later replaced with a SuspiciouslySimilarSubstitute named Kennedy.
[[/folder]]

[[folder:Video Games]]
* After premiering in the arcade title ''VideoGame/{{Flicky}}'', Flicky ends up crossing over into ''Franchise/SonicTheHedgehog'' as one of the many animal friends in need of rescue from Eggman's machinations. Flickies as a species became some of the most iconic of Sonic's animal buddies, which earned them ADayInTheLimelight with ''VideoGame/Sonic3DFlickiesIsland'', which was basically the original Flicky concept adapted to the Sonic world in isometric 3D.
* Seath from ''VideoGame/KingsField'' would later appear in Creator/FromSoftware's more recent medieval video game, ''VideoGame/DarkSouls'', as Seath the Scaleless, one of the major lore figures in the ''Dark Souls'' mythos.[[spoiler:.. as well as one of the bosses.]]
* After the original NES trilogy concluded, ''VideoGame/NinjaGaiden'' star Ryu Hayabusa became one of the main fighters in the ''VideoGame/DeadOrAlive'' series. Years later, {{Canon Immigrant}}s would jump back and forth between the Team Ninja revival of ''Ninja Gaiden'' and the later ''DOA'' titles (particularly ''VideoGame/DeadOrAlive5'').
* ''Franchise/{{Persona}}'':
** The female protagonist of ''VideoGame/ShinMegamiTenseiIf'' made an appearance as a NPC named Tamaki Uchida in the first ''VideoGame/{{Persona|1}}'', where she talks about her experience fighting demons. She also shows up in the ''VideoGame/Persona2'' duology. Her appearance is often cited as proof that the ''Persona'' games take place in the same universe as ''if...''.
** Additionally, the Devil Summoner possessing Daisuke Todoroki in ''Persona 2'' is implied to be Kyouji Kuzunoha from the original ''VideoGame/DevilSummoner'' and ''VideoGame/SoulHackers''.
** ''VideoGame/Persona4Arena'' features three of the heroes from ''VideoGame/Persona3'' as playable characters and important figures in the story: Mitsuru Kirijo, Akihiko Sanada, and Aigis. ''VideoGame/Persona4ArenaUltimax'' adds three more characters; Yukari Takeba, Junpei Iori, and Ken Amada (alongside Koromaru). [[spoiler:Fuuka Yamagishi also appears in the story. Shinjiro Aragaki, unfortunately, is confirmed to have canonically died.]]
* Sonny Bonds, protagonist of the first three ''VideoGame/PoliceQuest'' games, appears in the spin-off ''VideoGame/{{SWAT}}'' series minus the first game. ''[[VideoGame/PoliceQuestSWAT2 SWAT 2]]'' has him as a playable character, having been transferred from [[CityOfAdventure Lytton]] to Los Angeles, in ''VideoGame/SWAT3'', he has been promoted to SWAT leader, and by ''VideoGame/SWAT4'', he's a SWAT veteran who now trains new recruits.
* In ''VideoGame/{{Smite}}'', Grover was a treant who used to be the mount of Sylvanus and only spoke in gibberish. Grover would later appear in ''VideoGame/{{Paladins}}'' as his own playable character and can speak coherently.
* Creator/{{SNK}}:
** The main characters of the ''VideoGame/FatalFury'' and ''VideoGame/ArtOfFighting'' series continued making appearances in ''Franchise/TheKingOfFighters'' series years after both series' respective last installments: ''VideoGame/GarouMarkOfTheWolves'' (1999) and ''Path of the Warrior: Art of Fighting 3'' (1996).
** In a related example, ''VideoGame/IkariWarriors'' Ralf Jones and Clark Still (also members of the massive ''KOF'' roster) returned to their run-and-gun roots in ''VideoGame/MetalSlug 6'' and ''7'', presumably returning the favor for Fio joining the roster in ''Maximum Impact 2''. Leona would be added as [[DownloadableContent a downloadable character]] in ''Metal Slug XX'', an UpdatedRerelease of ''7''.
** And before that, Ralf Jones was actually in ''TNK III'' before he permanently moved over to ''Ikari Warriors''.
* ''Franchise/StreetFighter'':
** This was the fate of several ''VideoGame/FinalFight'' characters, thanks to the series [[SharedUniverse sharing a setting with]] ''Street Fighter''. Guy and Sodom crossed over into ''VideoGame/StreetFighterAlpha''. Rolento followed suit in ''Alpha 2'', and Cody joined the roster in ''Alpha 3''. Hugo ([[WordOfGod who is Andore]]) first appeared in ''VideoGame/StreetFighterIII: [[ColonCancer 2nd Impact]]''. Maki (from ''Final Fight 2'') became an AscendedExtra in ''[[VideoGame/CapcomVsSNK2MarkOfTheMillennium Capcom vs. SNK 2]]'' before [[CanonImmigrant being added to]] [[CapcomSequelStagnation updated releases]] of ''Alpha 3'' (the GBA port and then ''Alpha 3 MAX'' for the PSP). Guy and Cody returned in ''[[CapcomSequelStagnation Super]] VideoGame/StreetFighterIV'', and Poison (after spending years as Hugo's manager) [[PromotedToPlayable became playable]] in ''VideoGame/StreetFighterXTekken'', alongside Hugo, Rolento, Guy, and Cody (with Guy and Cody as [[DownloadableContent DLC]]). Rolento, Hugo, and Poison are also in ''[[CapcomSequelStagnation Ultra Street Fighter IV]]'', taken directly from their appearances in ''[=SFxT=]''. Abigail would then make a surprise appearance in ''VideoGame/StreetFighterV''[='s=] Season 2 wave of DLC, followed by a returning Cody in S3 and ''Final Fight 3''[='s=] Lucia in S4, with Poison also returning in S4. Other characters from the series (Haggar, Jessica, Carlos, Edi. E, the remainder of the Mad Gear Gang) make cameos around the aforementioned characters.
** Speaking of ''Street Fighter'', [[{{Ojou}} Blair]] [[KickChick Dame]] and [[{{Shotoclone}} Allen Snider]] from ''VideoGame/StreetFighterEX'' were [[PutOnABus bussed]] to Arika and Namco's fighting game, ''VideoGame/FightingLayer''. Though absent in ''[=EX2=]'' and ''[=EX3=]'', they did ultimately return alongside the rest of the Arika [[CanonForeigner originals]] for both series' [[CreatorDrivenSuccessor spiritual sequel]], ''VideoGame/FightingEXLayer''.
** And speaking of ''Street Fighter V'' specifically, the fifth and final season of DLC saw Akira from ''VideoGame/RivalSchools'' join the cast. Long before then, Sakura was a GuestFighter in the first ''Rival Schools'' and noted to be friends with Hinata and Natsu, though the canonicity of the ties between games was somewhat dubious at the time. It wasn't until the UDON comics where ''Rival Schools'' characters constantly showed up did it become widely accepted that the two series [[SharedUniverse shared continuity]].
* ''Franchise/SuperMarioBros'': The Shy Guys, the Bob-Ombs, the Pokeys and Birdo were initially characters from ''VideoGame/DokiDokiPanic''. The game was [[DolledUpInstallment dolled up]] to become the Western version of ''VideoGame/SuperMarioBros2'', which was then also released in Japan as ''Super Mario USA'', the fourth entry for the NES over there. Other characters from the game have also appeared sporadically over the years, such as Mouser and the Ninji, but these four are the most recurring and famous transplants.
* ''VideoGame/TokyoXanadu'': The protagonist's homeroom teacher, Towa Kokonoe, is -- technically speaking -- a transplant from the ''VideoGame/TrailsSeries'', where she was known as Towa Herschel and was a second-year student in the Thors Academy. Both versions are nearly identical in personality and appearance, both are voiced by Creator/AiNonaka in Japanese, and Herschel eventually becomes a teacher in the sequels of [[VideoGame/TheLegendOfHeroesTrailsOfColdSteel her game]]. (The prevailing theory is that, as opposed to merely being a ReusedCharacterDesign of her ''Trails'' counterpart, Towa Kokonoe is an AlternateSelf of Towa Herschel, furthered by how both ''Tokyo Xanadu'' and ''[[VideoGame/TheLegendOfHeroesTrailsIntoReverie Trails into Reverie]]'' make mention of a ''[[ShowWithinAShow Magical Girl Alisa]]'' series which, true to its name, features ''Trails of Cold Steel'' characters in a MagicalGirl setting.)

[[folder:Web Animation]]
* Player and Veteran originated from the ''Fall Guys Logic'' series before becoming the protagonists of ''WebAnimation/AmongUsLogic''. The two occasionally lampshade it.
--> '''Player:''' ''(after being ejected into space)'' [[LeaningOnTheFourthWall I knew I should've stuck to]] ''VideoGame/FallGuys''.
* The WebVideo/{{Revengeverse}} has various examples:
** Doctor Pandemia debuted on ''WebVideo/CelioVsZombies'' before being a recurring character on ''WebVideo/AitorMolinaVs''.
** Reddy Wizard from [[OldShame Red Leo Media]] became a relevant character after the cancelation.
** {{Deconstructed|Trope}} with Aitor Molina being Transplanted from the original continuity to the Revengeverse.

[[folder:Webcomics]]
* In the case of an entire cast turnover, the squid kids of ''Webcomic/HeroesOfInkopolis'' and ''Cafe Cardamari Tales'' were eventually repurposed into members of the Glass species in Tamarinfrog's following original comic ''Bottled Up''.
* The [[QuirkyMinibossSquad Midnight Crew]] in ''Webcomic/MSPaintAdventures'' first appeared as comical antagonists against [[Webcomic/ProblemSleuth Team Sleuth]] in non-canon, donation-driven strips. In ''Webcomic/{{Homestuck}}'', all four members of the Midnight Crew appear to show up again as agents of Derse. At first it just seems like Jack Noir, Draconian Dignitary, Courtyard Droll and Hegemonic Brute are SuspiciouslySimilarSubstitutes for the Midnight Crew, but then it was [[SubvertedTrope subverted]] when the ''actual'' Midnight Crew showed up as their [[AlternateSelf alternate universe counterparts]].
* Gavin from ''Webcomic/{{Nukees}}'' joined ''Webcomic/SchlockMercenary''. En masse through cloning, as it happens.
* [[DoubleSubversion Double Subverted]] with Kestrel of ''Webcomic/QueenOfWands'' moving to ''Webcomic/SomethingPositive''. The strips had several crossovers, and ''[=QoW=]'' ended with Kestrel moving to Boston, where ''S*P'' took place. Fans wondered if she would join the ''S*P'' cast, so as a joke, right after her comic ended there was a ''S*P'' strip where she spots the main characters, tries to get their attention...[[DroppedABridgeOnHim and suddenly gets hit by a car]]. It was meant to subvert the idea, but when ''Webcomic/QueenOfWands'''s author kept getting questions about whether that ending was "canon", she decided to just sell the rights to Kestrel to ''S*P''. She has appeared occasionally since then (having apparently spent some time in the hospital since her accident), but remains quite OutOfFocus, especially since the comic now splits its time between Boston and Texas.

[[folder:Western Animation]]
* Following the cancellation of ''WesternAnimation/TheCasagrandes'', characters that originated from that series continue to make occasional appearances in ''WesternAnimation/TheLoudHouse''.
* Once ''WesternAnimation/TheClevelandShow'' was canceled, the title character and his family [[WesternAnimation/FamilyGuy moved back to Quahog]].
* Professor XXXL from ''WesternAnimation/CodenameKidsNextDoor'' was a character transplanted from Tom Warburton's failed pilot ''Kenny and the Chimp: WesternAnimation/DiseasyDoesIt''. Kenny and Chimpy, however, did not make the jump.
* The Red Guy from ''WesternAnimation/CowAndChicken'' eventually became the antagonist of ''WesternAnimation/IAmWeasel'' as well.
* Creator/VanPartible created two series for the ''WesternAnimation/WhatACartoonShow'': ''WesternAnimation/JohnnyBravo'' and ''Jungle Boy''. The first season of Johnny Bravo (helmed by Partible) incorporated Jungle Boy and his supporting cast into Johnny Bravo's cast, but after Partible was fired, the characters were dropped for the rest of the show.
* WesternAnimation/DonaldDuck began as a one-off character in the ''WesternAnimation/SillySymphonies'' short "The Wise Little Hen". Like so many other ''Silly Symphonies'' characters before him, the duck was expected to remain a one-off character. However, director Burt Gillett liked the duck so much that he brought him back for the ''WesternAnimation/MickeyMouse'' short "Orphan's Benefit", and the response that Disney got about Donald following the short's debut was overwhelmingly positive. Immediately afterwards, the duck was made a major character in the ''Mickey Mouse'' series and the rest is history.
* Launchpad [=McQuack=] was transplanted to ''WesternAnimation/DarkwingDuck'' after ''WesternAnimation/DuckTales1987'' ended, though he was originally planned to be transplanted into ''WesternAnimation/TaleSpin'' instead. Fenton Crackshell/Gizmoduck also popped up from time to time. Tad Stones, who created ''Darkwing Duck'', later revealed that this was a case of parallel universes rather than one show being a sequel to the other, as fans generally assumed.
* Goat is a character based on a friend of Creator/{{Titmouse}} founder Chris Prynoski that has been a supporting character in both ''WesternAnimation/{{Downtown}}'' and ''WesternAnimation/MegasXLR'' (voiced by the person he's based on and occasionally credited as "Goat" or "Himself"). He also has a brief appearance in ''WesternAnimation/{{Metalocalypse}}''.
* General Reginald Skarr from ''WesternAnimation/EvilConCarne'' moved into the title characters' neighborhood on ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' after his show was canceled.
* Ever since the ''WesternAnimation/{{Futurama}}/WesternAnimation/TheSimpsons'' [[Recap/TheSimpsonsS26E6Simpsorama crossover episode]], Bender has made multiple non-speaking cameos in the basement of the Simpsons (or floating in the hall when it gets flooded), [[TheSlowPath once again waiting for a thousand years]].
* Creator/CraigMcCracken:
** Ace of the Gangreen Gang, a main villain from ''WesternAnimation/{{The Powerpuff Girls|1998}}'', became the replacement for Murdoc Niccals in Phase 4 of Music/{{Gorillaz}} after the latter got arrested. It helps that Craig [=McCracken=] and Damon Albarn are friends in real life.
** On the show's receiving end, Major Glory, the protagonist of the "Justice Friends" segments from ''WesternAnimation/DextersLaboratory'', is a major character in the episode "Members Only", where he sports a notably different design from his original show. It shouldn't be surprising since [=McCracken=] was the art director of the first two seasons of ''Dexter's Laboratory'', and its creator Creator/GenndyTartakovsky likewise worked with [=McCracken=] on ''The Powerpuff Girls''.
* ''WesternAnimation/OKKOLetsBeHeroes'':
** An unusual example: one of the P.O.I.N.T. Prep students introduced in Season 2 is Koala Princess, who was the heroine of a ShowWithinAShow from another show Ian Jones-Quartey worked on, ''WesternAnimation/StevenUniverse''.
** The President of the Universe was a one-shot supporting character on ''WesternAnimation/SecretMountainFortAwesome'', another entry in Jones-Quartey's CV.
** Gertie also came from ''Secret Mountain Fort Awesome'', but in her case the episode she was made for [[UnfinishedEpisode was never completed]].
* ''WesternAnimation/PhineasAndFerb'''s resident evil scientist Dr. Heinz Doofenshmirtz becomes a recurring character in Season 2 of ''WesternAnimation/MiloMurphysLaw'', having given up evil [[Recap/PhineasAndFerbLastDayOfSummer in the finale of his native show]] and needing a place to stay after his building was destroyed [[Recap/MiloMurphysLawS2E01ThePhineasAndFerbEffect in the crossover]]. Perry the Platypus and Major Monogram also play a recurring role, as while Doofenshmirtz [[HeelFaceTurn is no longer evil]], his attempts at being good have collateral damage that needs to be fixed.
-->'''Norm:''' Who are these people?\\
'''Dr. Doofenshmirtz:''' Oh, sorry, Norm. This is a whole new series... [[FourthWallPsych of events that have transpired]].
* Figaro from ''WesternAnimation/{{Pinocchio}}'' has appeared in several WesternAnimation/ClassicDisneyShorts, ''WesternAnimation/HouseOfMouse'' and ''WesternAnimation/MickeyMouseClubhouse'' episodes as WesternAnimation/MinnieMouse's pet.
* Echo ([=CT=]-1409) started out as one of the recurring Clone Troopers in ''WesternAnimation/StarWarsTheCloneWars''. After spending some time missing and presumed dead, he returned in the [[PoorlyDisguisedPilot "Bad Batch" arc]] where he joined the eponymous team, thus becoming a main character in the SequelSeries ''WesternAnimation/StarWarsTheBadBatch''.
* Years before Creator/RebeccaSugar created ''WesternAnimation/StevenUniverse'', Sadie and Lars were characters in some unpublished comics she made while attending college.
* Quite a few cross-medium transplants occurred from Vasquez's ''ComicBook/{{Squee}}'' comics to his animated series ''WesternAnimation/InvaderZim''. Squee's teacher was named Ms. Bitters and became the teacher of Zim's class, while the horned aliens from issue one of ''Squee'' became the Vortian race that made frequent appearances on ''Zim''. Conversely, the wheelchair-bound aliens that regularly appeared in the pages of ''Squee'' only appear in one episode of ''Zim''.
* Several of the Creator/{{Sunbow|Entertainment}} cartoons based on Hasbro properties had characters appear throughout the different series to indicate a SharedUniverse.
** The character Hector Ramirez made his debut in ''WesternAnimation/GIJoeARealAmericanHero'' and made at least one appearance in ''WesternAnimation/TheTransformers'', ''WesternAnimation/{{Jem}}'' and ''WesternAnimation/{{Inhumanoids}}''.
** The ''Inhumanoids'' character Sabre Jet is hinted to be the same character as Ace from ''G.I. Joe'' due to both characters having the real name of Brad J. Armbruster.
** The third season of ''The Transformers'', which took place in the future, had an episode titled "Only Human" that featured an antagonist named Old Snake, who is strongly implied to be an aged Cobra Commander.
* ''WesternAnimation/TinyToonAdventures'':
** Several years before before Ralph the security guard was a supporting character in ''WesternAnimation/{{Animaniacs}}'', he was a unnamed minor character in ''Tiny Toon Adventures''. Likewise, Mr. Skullhead (the character featured in the "Good Idea, Bad Ideas" sketches) got an EarlyBirdCameo as an ImaginaryFriend of Elmyra's featured in the first PoorlyDisguisedPilot for a series about her family.
** Speaking of ''Tiny Toons'', Elmyra was infamously transplanted in the ''Animaniacs'' spinoff ''WesternAnimation/PinkyAndTheBrain'', creating the short-lived SequelSeries ''WesternAnimation/PinkyElmyraAndTheBrain''.
* ''Franchise/TomAndJerry'':
** Modern revivals of ''Tom and Jerry'', beginning with [[WesternAnimation/TheTomAndJerryComedyShow the 1980 Filmation series]], have brought in other MGM cartoon characters, including WesternAnimation/{{Droopy}}, WesternAnimation/BarneyBear, and [[WesternAnimation/TexAveryMGMCartoons Red]] among others.
** The 1941 WesternAnimation/{{MGM Oneshot Cartoon|s}} ''The Alley Cat'' introduced the intially one-off characters of Butch and Toodles Galore, who were then integrated into the ''Tom and Jerry'' franchise.
* ''WesternAnimation/TotalDrama'':
** ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'' has a few contestants from the original ''Total Drama'' as participants in the race, namely Noah, Owen, and Geoff. [[MyFriendsAndZoidberg Oh, and Leonard's there too.]]
** ''WesternAnimation/TotalDramaRama'' has Jude Lizowski from ''WesternAnimation/{{Sixteen}}'' as one of the daycare kids.
