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 Spin-Off gets canned. When this happens, they'll often transplant back to their show of origin, with some flimsy explanation; if this happens, the chances of a Fully Absorbed Finale go way up. See also Rogues-Gallery Transplant, a more specific variant of this trope where a villain from a superhero's Rogues Gallery shifts to fighting someone else. Compare Canon Immigrant. Not to be confused with the wiki operation that is also called a Trope Transplant.

    Anime & Manga 
  • Manga example: Subaru from Tokyo Babylon becoming part of the cast of X1999. His Arch-Enemy, Sakurazuka Seishirou, joins the cast as his opposite while his twin sister makes cameos.
  • Katori Matou from Roman Club joins Amanchu as scuba club advisor and Hikari's homeroom teacher.
  • One of the teachers in Wandering Son was a character in Shiki no Juunin .
  • After Mahou Sensei Negima! ended, Evangeline, who now goes by Yukihime, moved on to the Stealth Sequel series UQ Holder. Later on, Fate, one of the primary antagonists of Negima and other characters like Mana also show up.
  • In chapter 47 of Boku No Hero Academia, Momo and Kendou got internship under Snake Heroine Uwabami. Her name and design is lifted straight from Uwabami from Oumagadoki Doubutsuen, 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.

  • At the end of Ultimate Power, an Intercontinuity Crossover between Ultimate Marvel and the Supreme Power universe, Zarda and Nick Fury switched places. The latter is a major character in the post-Time Skip new Supreme Power series, while the former had some Destructo-Nookie with the Hulk. After Ultimatum, Nick Fury crossed back over.
  • Ultimate Spider-Man 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. And after a Wham Miniseries and subsequent Time Skip, the Parkers have taken in refugees from canceled series: Human Torch and Iceman.
  • Peter David's Sachs and Violens, of the mini-series of the same name, were transplanted ten years later to Fallen Angel.
  • Charity, the onetime Horror Host of 70s DC "Weird" horror title Forbidden Tales Of Dark Mansion, later shows up in the 1990s Starman series.
  • The entire roster of Quality, Fawcett, and Charlton Comics superheroes were transplanted into the DC Universe after DC bought them all.
  • The Sandman 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.
  • A lot of 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 X-Men character. Domino, Taskmaster, ZERO, Dr. Bong, Sandi Brandenberg, Outlaw, and Deuce the Devil-Dog are just a few examples. Cable, while not fully transplanted from the X-Men, is more often remembered for his partnership with Deadpool than any of his other escapades.

    Fan Works 
  • In a Homestar Runner fan series called "The Homestar Runner Show," Weena from The Time Machine is a regular character, even having some cartoons where she is the main character!

  • L. Frank Baum wanted to move away from the 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 getting immediately Demoted to Extra there.
  • Professor Chronotis in Dirk Gently's Holistic Detective Agency was originally a character created for the Development Hell Doctor Who episode "Shada" as a retired Time Lord and an Eccentric Mentor for the Doctor. Knowing this makes some of the weirder things about him - his casual mentions of being thousands of years old, having other faces, and having a Bigger on the Inside time machine - make an awful lot more sense.
  • Granny Weatherwax and Nanny Ogg are the primary main characters of 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, most namely as mentors to Discworld to Tiffany Aching, who has her own series.
  • Jas, the Winged Humanoid from the Spelljammer comics by Jeff Grubb and Kate Novak, later joined Finder's Band in the same authors' Forgotten Realms novels.

    Live-Action TV 
  • Kenneth the Page, the Ensemble Dark Horse of 30 Rock, was originally a character on Late Night with Conan O Brien. Strangely, even after the show was a success, he continued to appear on Late Night and even stayed with Conan when he moved to The Tonight Show.
  • There were quite a few of these in Angel. In fact, in the latter half of the first season, all three main characters were Transplants from Buffy the Vampire Slayer: Angel, Cordelia Chase, and Wesley Wyndam-Pryce. Then in the fifth season — after Buffy had ended — Spike was Transplanted to Angel as well. Also in the latter half of the fifth season, Harmony (a character who originated on Buffy and appeared in both series) was made a regular on Angel.
  • Detective Munch joining the cast of Law & Order: Special Victims Unit after Homicide Life On The Street went off the air. Law and Order: Special Victims Unit has another character, Captain Cragen, from the early seasons of Law & Order. Det. Lennie Briscoe went from Law and Order to Law & Order: Trial by Jury, though only a few episodes were filmed with him prior to actor Jerry Orbach's death.
  • Chief Miles O'Brien was a main character on Star Trek: Deep Space Nine, having originated as a recurring guest character on Star Trek: The Next Generation. 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 The Movie Generations.
    • They attempted to transplant Next Gen recurring character Ensign Ro Laren to a spinoff series twice, but each time actress Michelle Forbes refused due to reluctance to be tied to a six-year contract. Each time, the role planned to be Ro Laren was rewritten as an original character: for Deep Space Nine it became Major Kira Nerys, and for Star Trek: Voyager it became Lieutenant B'Elanna Torres.
    • Again, this almost happened in Voyager, with Nick Locarno (a guest character from the TNG episode "The First Duty") being planned to be brought back as a main character. When it became apparent they wouldn't be able to bring back the character due to rights issues, they hired the guy who'd played Locarno, wrote for him a new character who was basically the same guy with a few details changed, and named him Tom Paris.
      • The same thing probably happened with Taurik, a Vulcan engineer who was the focus of one episode of Star Trek: The Next Generation. The same actor later played a recurring Vulcan engineer named Vorik on Voyager.
    • Enterprise-D crewman Reginald Barclay also popped up on Star Trek: Voyager, actually making exactly the same number of appearances in both series.
  • The short-lived Stephen Bochco 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 L.A. Law after the cancellation of their series.
  • A relatively unimportant and yet much-beloved recurring character on Stargate SG-1, Dr. Rodney McKay, crossed over to Stargate Atlantis. 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. Amanda Tapping 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 IOA agent Richard Woolsey (yet another transplant from SG-1 who had recurring appearances in Atlantis before), Carter had a guest appearance in the Grand Finale, "Enemy at the Gate". She wasn't intended to only be in one season, but Amanda Tapping wanted to leave to pursue Sanctuary so they had to replace her.
    • O'Neill has now been transplanted to Stargate Universe.
  • Deputy Enos Strait returned to The Dukes of Hazzard when his Atlanta-based spinoff ended after one season.
  • Florence returned to The Jeffersons after her spin-off died a quick death.
  • Joanie Loves Chachi's power-couple returned to Happy Days.
  • The Lone Gunmen was a short-lived spin-off The X-Files. They returned for one episode In which they die heroically. However, Chris Carter has said that nobody really dies for good in that verse...
  • The popular couple Kevin and Lucy from the soap opera General Hospital 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 The Sopranos and PC had become a daytime romance novel version of Buffy the Vampire Slayer 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 primetime 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 The Golden Girls (and subsequently The Golden Palace) ended, Sophia joined Empty Nest.
  • After Civil Wars was cancelled, attorney Eli Levinson and his secretary Denise Ianello joined the firm of McKenzie-Brackman on L.A. Law.
  • Helen DuBois, who goes from Josh's boss from Drake & Josh to the principal of Hollywood Arts in Victorious.
  • Senator Edward Sheffield, played by Dean Stockwell, first appeared in the short-lived Donald P. Bellisario produced U.S. Supreme Court series First Monday before he went over to JAG and became the Secretary of the Navy.
  • E.L. "Tenspeed" Turner of 1980's Tenspeed And Brown Shoe turned up in 1987 as a supporting character on JJ Starbuck.
  • After the cancellation of Once Upon a Time in Wonderland, it was announced that Michael Socha's character Will Scarlet would be moved to the show's parent series.
  • When the first of the two Saved by the Bell spinoffs, The College Years, ended Screech was moved over to the other spinoff, The New Class, for the remainder of the show.
  • With the cancellation of the original 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 CSI: Cyber.
  • Power Rangers Lost Galaxy had Alpha 6, Bulk, and Professor Phenomenus are transplants from the "Zordon Era" of the Power Rangers timeline, as Lost Galaxy onwards would adapt Super Sentai's "standalone seasons" method.

    Video Games 
  • The main characters of the Fatal Fury and Art of Fighting series continued making appearances in The King of Fighters series years after both series' respective last installments: Garou: Mark of the Wolves and Path of the Warrior: Art of Fighting 3.
    • In a related example, Ikari Warriors Ralf Jones and Clark Still (also members of the massive KOF roster) returned to their run-and-gun roots in Metal Slug 6 and 7, presumably returning the favor for Fio joining the roster in Maximum Impact 2. Leona would be added as a downloadable character in Metal Slug XX, an Updated Re-release of 7.
    • And before that, Ralf Jones was actually in TNK III before he permanently moved over to Ikari Warriors.
  • Ditto with the cast of Final Fight, who had an Intercontinuity Crossover with Street Fighter. Guy and Sodom crossed over into Street Fighter Alpha. Rolento followed suit in Alpha 2, and Cody joined the roster in Alpha 3. Hugo (who is Andore) first appeared in Street Fighter III: 2nd Impact. Maki (from Final Fight 2) became an Ascended Extra in Capcom vs. SNK 2 before being added to updated releases of Alpha 3 (the GBA port and then Alpha 3 MAX for the PSP). Guy and Cody recently returned in Super Street Fighter IV, and Poison (after spending years as Hugo's manager) is playable in Street Fighter X Tekken, alongside Hugo, Rolento, Guy, and Cody (with Guy and Cody as DLC). Rolento, Hugo, and Poison are also in Ultra Street Fighter IV, taken directly from their appearances in SFxT. Other characters from the series (Haggar, Jessica, Carlos, Edi. E, the remainder of the Mad Gear Gang) make cameos around the aforementioned characters.
  • Miku of the first Fatal Frame joined the cast of the third game.
  • Seath from King's Field appeared in Dark Souls as one of the major lore figures and bosses.
  • After the original NES trilogy concluded, Ninja Gaiden star Ryu Hayabusa became one of the main fighters in the Dead or Alive series. Years later, Canon Immigrants would jump back and forth between the Team Ninja revival of Ninja Gaiden and more recent DOA titles (particularly Dead or Alive 5).
  • The female protagonist of Shin Megami Tensei If made an appearance as a NPC named Tamaki Uchidal. in Persona, where she talks about her experience fighting demons. She also shows up in Persona2 duology. Her appearance is often cited as proof that the Persona games take place in the same universe as if....
  • Sonny Bonds, protagonist of the first three Police Quest games, appears in the spin-off S.W.A.T. series minus the first game. SWAT 2 has him as a playable character, having been transfered from Lytton to Los Angeles, in SWAT3, he has been promoted to SWAT leader, and by SWAT4, he's a SWAT veteran who now trains new recruits.

  • After a couple of crossovers, Kestrel from webcomic Queen of Wands joined Something*Positive when Queen of Wands finished, and still appears there. It's worth mentioning however that Something Positive fooled just about everyone into thinking this wouldn't happen, after they had Kestrel apparently crushed by a hit and run driver.
    • Explanation: The original appearance was a joke. Something Positive only got full rights shortly before Kestrel's 'real' appearance.
  • Gavin from Nukees joined Schlock Mercenary. En masse, as it happens.
  • The Midnight Crew in MS Paint Adventures first appeared as comical antagonists against Team Sleuth in non-canon, donation-driven strips. In Homestuck, all four members of the Midnight Crew appear to show up again, this time as real adversaries, with someone who eerily resembles Spades Slick acting as The Starscream. This fact is lampshaded in his formal introduction when the narrator tries to name him Spades Slick.

    Western Animation 
  • General Reginald Skarr from Evil Con Carne moved into the title characters' neighborhood on The Grim Adventures of Billy & Mandy after his show was canceled.
  • Launchpad McQuack was transplanted to Darkwing Duck (initially planned for TaleSpin) after DuckTales ended. Gizmoduck also popped up from time to time.
  • A fairly obscure example is Goat of Megas XLR, who originated in a short-lived MTV show called Downtown. He's based on a friend of the creators, who also provides the character's voice and is occasionally credited as "Goat" or "Himself".
    • Goat later showed up on Metalocalypse, too. He sure gets around, doesn't he?
  • Figaro from Pinocchio has appeared in several Classic Disney Shorts and House of Mouse as Minnie Mouse's pet.
  • The Red Guy from Cow and Chicken eventually became the antagonist of I Am Weasel as well.
  • A cross-medium transplant occurred from Squee to Invader Zim, the former being a comic and the latter being an animated show. Squee's teacher was named Ms. Bitters and became the teacher of Zim's class, and the horned aliens from issue one of Squee became the Vortian race and showed up much more frequently on Zim. Conversly, the wheelchair-bound aliens—which had shown up a good deal in Squee—only appear in one episode of Zim.
  • Upon the cancellation of The Cleveland Show the title character and his family move back to Quahog.
