History Main / DoppelgangerCrossover

** Speaking of Taylor, the character was brought back to repair a clogged sink of Allen's other character Mike Baxter for the final season of ''Series/LastManStanding''.

** In the ''Ghostbusters 101'' crossover comic where the Ghostbusters from the [[Film/Ghostbusters1984 1984]] and [[Film/Ghostbusters2016 2016]] movies meet eachother. Erin notes that Stantz looks identical to the RemakeCameo taxi driver that Aykroyd played in her movie.

** Plenty of fanfics involve Lina Inverse from ''{{LightNovel/Slayers}}'' meeting up with female Ranma. Or the latter and Rei Ayanami of ''Anime/NeonGenesisEvangelion''. There was even one with Ai Amano from ''Manga/VideoGirlAi''. Blame Music/MegumiHayashibara and her amazingly prolific career.

* Creator/ClintEastwood: Fairly common in fan expansions of Creator/PhilipJoseFarmer's ''Wold Newton Universe'', but one of the most extensive is probably [[http://www.pjfarmer.com/woldnewton/Articles7.htm#NONAME this article]] about [[Film/TheDollarsTrilogy The Man With No Name]], which suggests that he was also [[Film/TheOutlawJoseyWales Josey Wales]], [[Film/TwoMulesForSisterSara Hogan]], [[Film/{{Unforgiven}} Will Muny]], [[Film/PaleRider The Preacher]], [[Film/HangEmHigh Jed Cooper]], [[Film/HighPlainsDrifter The Stranger]], and Film/JoeKidd. (Ironically, it also suggests he probably doesn't "really" look much like Clint Eastwood.) In addition, his descendants include:

** In ''Film/TransformersRevengeOfTheFallen'', Nimoy voices Sentinel Prime who allys with Megatron.

* The ''Film/HarryPotter'' and ''Literature/{{Twilight}}'' series both feature actor Creator/RobertPattinson in their respective film adaptations, although it would take some rather violent [[HandWave Hand Waving]] to make Cedric Diggory and Edward Cullen the same person. This has mostly been fodder for the [=MuggleNet=] caption contest. Cedric seems to have become a much more popular character in ''Harry Potter'' fanfiction since the first ''Twilight'' movie.

** ''Infinity'' allowed Creator/SamuelLJackson characters ComicBook/NickFury and Mace Windu of ''Franchise/StarWars'' to team up (though the latter is only an AssistCharacter and not fully playable). Unfortunately, even though WesternAnimation/TheIncredibles were part of the game, Frozone didn't show up with them.

* Creator/JohnRatzenberger: While not quite a full crossover, the credits of ''WesternAnimation/{{Cars}}'' sees the cast watch car versions of previous Creator/{{Pixar}} movies. Mack enjoys a handful of side characters until he realizes they're all the same voice actor; the joke being that it's Ratzenberger's character [[ButHeSoundsHandsome praising and then complaining about other Ratzenberger characters]].

Frank would later operate as a master thief under such aliases as [[Film/ThunderboltAndLightfoot Thunderbolt]] and [[Film/AbsolutePower Luther Whitney]] [...] Arizona deputy [[Film/CoogansBluff Walt Coogan]] and his cousin [[Film/TheGauntlet Ben Shockley]].

%% ** A series of fics have established that the Minister of Chance from ''Death Comes To Time'' is secretly ''every'' character Creator/StephenFry has ever played, ''especially'' [[Radio/AbsolutePower Charles Prentiss]].

* Creator/PedroPascal: What if [[Franchise/StarWars Din Djarin and Grogu]] met [[Series/TheLastOfUs2023 Joel Miller and Ellie Williams]]? The similarities of their journeys inspire several fanart of this scenario.

** An Creator/IDWPublishing ''[[ComicBook/GhostbustersIDWComics Ghostbusters 101]]'' crossover comic where the Ghostbusters from the [[Film/Ghostbusters1984 1984]] and [[Film/Ghostbusters2016 2016]] movies meet eachother. Erin notes that Venkman looks identical to the Martin Heiss RemakeCameo character from her movie.

** Creator/BoomStudios had a crossover between ''ComicBook/BigTroubleInLittleChina'' and ''ComicBook/EscapeFromNewYork'', having Kurt Russell's two characters meeting eachother.

** Claude from ''Series/{{Heroes}}'' being secretly the Ninth Doctor was a very popular idea for a time. Both were played by Creator/ChristopherEccleston. There was also one fic in which the Ninth Doctor was mistaken for Stephen Baxter from ''Series/TheSecondComing'', also played by Eccleston.
** A series of fics have established that the Minister of Chance from ''Death Comes To Time'' is secretly ''every'' character Creator/StephenFry has ever played, ''especially'' [[Radio/AbsolutePower Charles Prentiss]].

** The events of "The Name of the Doctor" mean that any character played by Creator/JennaColeman can be a fragment of Clara and [[FandomSpecificPlot save the Doctor's life in a crossover]].

** The naming of Creator/PeterCapaldi as the Twelfth Doctor launched a cavalcade of ''Series/TheThickOfIt'' crossovers, such as [[http://archiveofourown.org/works/919966 "In Space, No-One Can Hear You Scream Obscenities"]] and this [[https://www.youtube.com/watch?v=5Blf073f2Lc sweary trailer]].In ''The Thick Of It'', Capaldi plays Malcolm Tucker.
** After Creator/DavidTennant, who played the Tenth Doctor, was cast as Crowley in the ''Series/GoodOmens2019'' TV adaptation, many crossovers were written about the Tenth Doctor meeting Crowley with a reference to how the Doctor once lamented that he was never regenerated as a ginger usually thrown in there since Crowley just so happens to be ginger.
** There are umptynine ''Series/{{Life On Mars|2006}}'' fics that reveal that Sam Tyler is in fact... the Master from ''Doctor Who''. Both played by John Simm.

* The ''Film/HarryPotter'' and ''Literature/{{Twilight}}'' series both feature actor Creator/RobertPattinson in their respective film adaptations, although it would take some rather violent [[HandWave Hand Waving]] to make Cedric Diggory and Edward Cullen the same person. This has mostly been fodder for the [=MuggleNet=] CaptionContest. Cedric seems to have become a much more popular character in ''Harry Potter'' fanfiction since the first ''Twilight'' movie.

** The two characters also crossed over in VideoGame/{{LEGO Adaptation Game}}s; with Indy being a GuestFighter in ''VideoGame/LEGOStarWars: The Complete Saga'' and Han being one in ''VideoGame/LEGOIndianaJones: The Original Adventures''.

[[caption-width-right:350:Creator/KenjiOhba, Creator/KenjiOhba, and Creator/KenjiOhba.]]

* ''Literature/AnnoDracula'', being a MassiveMultiplayerCrossover which also find itself WritingAroundTrademarks a lot in modern periods, often creates a CompositeCharacter out of two characters played by the same actor (for instance, the Creator/LucyLiu character [[Film/KillBill O-Ren "Cottonmouth"]] [[Film/RiseBloodHunter Blake]] in ''Anno Dracula 1999: Daikaiju''). He also established in ''Dracula Cha-Cha-Cha'' that vampire secret agent [[Franchise/JamesBond Hamish Bond]] was sired by Sergeant Dravot from ''Film/TheManWhoWouldBeKing'', also played be Creator/SeanConnery.

* In the ''Franchise/StarTrek'' novel, ''[[Literature/Ishmael1985 Ishmael]]'' by Barbara Hambley has Spock go back in time and meet his ancestor Aaron Stempel[[note]]Spelled "Stemple" here[[/note]] from ''Here Comes The Brides''. Stempel was played by Mark Lenard who played Spock's father, Sarek in ''Series/StarTrekTheOriginalSeries''.

* Creator/JonLovitz: In ''WesternAnimation/TheSimpsons'' episode "[[Recap/TheSimpsonsS15E14TheZiffWhoCameToDinner]]" The Ziff Who Came To Dinner]], Homer takes Artie Ziff to Moe's and introduces him to other Simpsons characters that Lovitz voiced including Jay Sherman from ''WesternAnimation/TheCritic''. Ziff calls them all losers.

Ziff calls them all losers.

* Creator/DanAykroyd: In IDW Comics' ''ComicBook/{{Ghostbusters|IDW Comics}}'', it's a plot point that Ray Stantz, Aykroyd's character in ''Ghostbusters'', and Elwood Blues, Aykroyd's character in ''Film/TheBluesBrothers'', are counterparts from different branches of the multiverse.

* Creator/JimCarrey: The animated versions of ''Film/AceVentura'' and ''WesternAnimation/TheMask'' crossed over in a two-parter spanning both series. Both cartoons are based on movies where the title character is played by Jim Carrey.

** An Creator/IDWPublishing ''[[ComicBook/GhostbustersIDWComics Ghostbusters]]'' crossover comic where the Ghostbusters from the [[Film/Ghostbusters1984 1984]] and [[Film/Ghostbusters2016 2016]] movies meet eachother. Erin notices the '84 team look identical to their RemakeCameo characters from her movie.

** There are ''Series/{{Smallville}}''/''Supernatural'' crossovers in which the focus is on Jason Teague / Dean Winchester interactions, as the characters share a single actor, one Jensen Ackles. It also makes sense as the Winchester brothers are from Kansas and might be drawn to a town in their home state that is rumored to be filled with super powered beings and strange occurrences.

** The fic "[[http://www.whofic.com/viewstory.php?sid=5411 In the Cafe of Reasonable Comfort]]" has Rowan Atkinson in his multiple roles. Atkinson played an unofficial Ninth Doctor in ''The Curse of Fatal Death'', a spoof produced by the BBC as comic relief.
