4->''"So," Chekov clapped his hands in eagerness, "who's the problem?" When Riker pointed down at the deck, he blinked and said, "Oh, there he is." He knelt down and rolled the still-senseless Bester over, checking him for weapons. "Rather a handsome devil, isn't he?"''\
5''"We hadn't noticed," Worf growled.''

8Let's say you're a fanfic writer. Let's make another assumption and say that you like a particular actor and everything they've ever been in, because they were in it.
9
10It's entirely possible that you may write a Doppelgänger Crossover, a story in which two characters played/voiced by the same actor meet each other. Or that they ''are'' each other. In other words, a crossover which is only happening because the two sources share an actor.
11
12You may desperately want [[Series/StarTrekTheNextGeneration Riker]] to meet [[WesternAnimation/{{Gargoyles}} Xanatos]], or [[Manga/RanmaOneHalf Ranma Saotome]] to be a reincarnation of Manga/InuYasha, or you might just want to see what happens when [[Series/{{Farscape}} John Crichton]] takes the place of [[Series/StargateSG1 Cameron Mitchell]], and don't even ''start'' on what would happen if [[Franchise/StarWars Han Solo]] bumped into Franchise/IndianaJones. The end result, however is the same. A Doppelgänger Crossover.
13
14It's seen as "fun" by writers, despite the fact that one side of the Doppelganger Crossover sometimes *will* fare badly when facing the character on the other half. For example, [[Film/{{Hounddog}} Grasshopper]] would certainly suffer painfully if she was to fall into [[Film/{{Orphan}} Esther]]'s hands.
15
16On occasion, this can be one part of a MassiveMultiplayerCrossover. See also FanonWelding where fans speculate that two unrelated works are part of the same universe especially if the actor/actress plays similar characters. Compare IWantYouToMeetAnOldFriendOfMine. May be the cause of a CelebrityParadox.

27* Creator/TimAllen:
28** On ''Series/HomeImprovement'', Tim "The Tool Man" Taylor is seen in one episode interacting with a Buzz Lightyear toy, referencing Allen's role as the space ranger in ''WesternAnimation/ToyStory1''.
29** The character of Tim Taylor was brought back to repair a clogged sink of Allen's other character Mike Baxter for the final season of ''Series/LastManStanding''.
30* Creator/DanAykroyd:
31** 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.
32** In the ''Ghostbusters 101'' crossover comic where the Ghostbusters from the [[Film/Ghostbusters1984 1984]] and [[Film/Ghostbusters2016 2016]] movies meet each other. Erin notes that Stantz looks identical to the RemakeCameo taxi driver that Aykroyd played in her movie.
33* Creator/BruceCampbell: ''Army Of Darkness/Bubba Ho-Tep'' has Ash from ''Franchise/EvilDead'' teaming up with Elvis from ''Film/BubbaHoTep''.
34* Creator/JimCarrey:
35** 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.
36** Near the end of ''Film/LiarLiar'' when Fletcher is being wheeled off on a stretcher, Carrey can be seen in the background playing his Fire Marshall Bill character from ''Series/InLivingColor''.
37* Creator/SeanConnery: In ''ComicBook/TheLeagueOfExtraordinaryGentlemen: Black Dossier'', Allan Quatermain meets a LawyerFriendlyCameo of ''Franchise/JamesBond''. Both characters have been played by Sean Connery; the former in ''Film/TheLeagueOfExtraordinaryGentlemen''. Given Creator/AlanMoore's opinion of the ''League'' movie and his portrayal of the Bond character, this is probably a TakeThat
38* Buster Crabbe: Played a man in an episode of ''Series/BuckRogersInTheTwentyFifthCentury'' called Brigadier Gordon who's strongly implied to be an older ''Franchise/FlashGordon''. Crabbe had played both ''[[Film/FlashGordonSerial Flash Gordon]]'' and ''Film/BuckRogers'' in old serials.
39* Creator/BryanCranston: The satirical "alternate ending" of ''Series/BreakingBad'' included in DVD releases of has [[Series/MalcolmInTheMiddle Hal]] waking up and confiding in his wife Lois about [[AllJustADream dreaming to be]] Walter White.
40* Creator/KatrinaDevine: At the end of the ''Series/PowerRangersNinjaStorm''/''Series/PowerRangersDinoThunder'' crossover, Marah and Cassidy (both played by Devine) notice one another, and they each declare to their friends that while [[ButHeSoundsHandsome the other is stunning]], ''they're'' much prettier.
41* Creator/JohnDiMaggio: In the ''WesternAnimation/{{Futurama}}'' episode, "[[Recap/FuturamaS7E22LeelaAndTheGenestalk Leela And The Genestalk]]" Bender runs into Finn and Jake from ''WesternAnimation/AdventureTime''. Both Bender and Jake are voiced by [=DiMaggio=].
42* Creator/BuddyEbsen plays Barnaby Jones of ''Series/BarnabyJones''. Ebsen appeared briefly as Barnaby Jones on two other productions: a 1975 episode of ''Cannon'' and the 1993 film ''Series/TheBeverlyHillbillies''. (Jim Varney played Jed Clampett, the role Ebsen played on the television series, in the film).
43* Creator/HarrisonFord:
44** ''ComicBook/StarWarsTales'' #19, "Into the Great Unknown", has the Millennium Falcon crash land on a planet that turns out to be EarthAllAlong. It ends years later with ''Franchise/IndianaJones'' finding Han Solo's skeleton. (Canonicity of this comic is often disputed; ''Star Wars Tales'' is an official publication but some of the tales in it are officially apocryphal.)
45** 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''.
46* In the ''Magazine/DoctorWhoMagazine'' short story "Brief Encounters: Mistaken Identity", Lytton from "Ressurection of the Daleks" and "Attack of the Cybermen" visits a pub in the East End borough of Walford between the two stories, and is haunted by the fact the barman looks like his engineer Kiston, who was killed by the Daleks. Kiston was played by Lesley Grantham, who was also Dirty Den Watts in ''Series/EastEnders''.
47* Creator/MarkHamill: In a ''WesternAnimation/JusticeLeagueAction'' web short called "Missing the Mark", the Joker and the Trickster - both played by Mark Hamill in this (among many other) series - kidnap the actual actor to ransom him to the studios. Yes, Swamp Thing, who appears near the end, is also played by Hamill in this series.
48* Creator/ErnieHudson: An Creator/IDWPublishing ''[[ComicBook/GhostbustersIDWComics Ghostbusters 101]]'' crossover comic where the Ghostbusters from the [[Film/Ghostbusters1984 1984]] and [[Film/Ghostbusters2016 2016]] movies meet eachother. Patty notes that Winston looks like a younger version of her uncle Bill who Hudson played in her movie.
49* Creator/DwayneJohnson: ''VideoGame/DisneyMirrorverse'' includes both Maui from ''WesternAnimation/{{Moana}}'' and Frank Wolff from ''Film/JungleCruise'' on its roster.
50* Creator/LisaKudrow: Lisa Kudrow's Ursula from ''Series/MadAboutYou'' started showing up in ''Series/{{Friends}}'' as Phoebe's identical twin sister.
51* Creator/JohnDeLancie: ''ComicBook/MyLittlePonyFriendshipIsMagicIDW'': ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', the Season 2 villain Discord is inspired by the RealityWarper Q from ''Series/StarTrekTheNextGeneration'', even being played by the same actor, John de Lancie. The fact the Discord ''is'' Q is played with in the official IDW comic. Specifically, in the second issue of the ''Friends Forever'' series, Discord creates a series of artificial reality scenarios to help the CMC get their cutie marks. One such scenario involves all of them as the command crew on the bridge of a starship greatly resembling the Enterprise, their costumes lifted directly from the cast of TNG. Discord (wearing the outfit Q wore in his debut) even comments that "this one seems familiar".
52* Creator/MarkLenard: 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 Lenard, as was Spock's father, Sarek.
53* 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.
54* Creator/BillMurray:
55** The Operations Manual for West End Games' ''Franchise/{{Ghostbusters}}: A Frightfully Cheerful Roleplaying Game'', published in 1986, contains an adventure titled "The Couch Potato," in which (assuming the players are using the characters from the movie) Dr. Peter Venkman meets a character named Dr. Hunter Panama. The manual notes right away that Doctor Panama is based on Dr. Hunter Thompson and suggests watching the movie ''Film/WhereTheBuffaloRoam'', in which he is played by Bill Murray (who, in case you can't guess, also played Dr. Venkman), to give you ideas on how to play the character. The manual also remarks that two Bill Murray characters playing off each other appeals to their schizophrenia.
56** An Creator/IDWPublishing ''[[ComicBook/GhostbustersIDWComics Ghostbusters 101]]'' crossover comic where the Ghostbusters from the [[Film/Ghostbusters1984 1984]] and [[Film/Ghostbusters2016 2016]] movies meet each other. Erin notes that Venkman looks identical to the Martin Heiss RemakeCameo character from her movie.
57* Creator/LeonardNimoy: While Nimoy technically didn't voice Megatron from the ''Franchise/{{Transformers}}'' franchise, in ''WesternAnimation/TheTransformersTheMovie'' Megatron turns into Galvatron who was voiced by Nimoy.
58** Nimoy's iconic Mr Spock from ''Series/StarTrekTheOriginalSeries'' meets Megatron in ''ComicBook/StarTrekVsTransformers''.
59** In ''Film/TransformersDarkOfTheMoon'', Nimoy voices Sentinel Prime who allys with Megatron.
60* Creator/JohnRatzenberger: While not quite a full crossover, the credits of ''WesternAnimation/Cars1'' 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]].
61* Creator/RyanReynolds:
62** ''{{ComicBook/Deadpool}}'''s schtick is that he knows he's a fictional character. So naturally, ''{{Film/Deadpool|2016}}'' has him take jabs at the previous mouthless version of Deadpool from the Wolverine movies, at the ''Film/GreenLantern2011'' movie, and claims that Ryan Reynolds certainly doesn't owe his film career to his acting talent.
63** In ''Film/Deadpool2'' Deadpool goes back in time to eliminate, not just the aforementioned no-mouthed version of Deadpool, but even ''Ryan Reynolds'' just before he can start filming the lead role in the ''Film/GreenLantern2011'' movie.
64* Creator/SethRogen: In ''Film/ChipNDaleRescueRangers2022'', [[WesternAnimation/TheLionKing2019 2019 Pumbaa]], [[WesternAnimation/KungFuPanda Mantis]], and [[WesternAnimation/MonstersVsAliens B.O.B]] appear at the convention to mock Bob the Dwarf, all four characters being played by Rogen. They even all do his signature laugh.
65* Creator/BrandonRouth: In the ''Series/{{Arrowverse}}'' crossover ''Series/CrisisOnInfiniteEarths2019'', he not only plays his normal role as ComicBook/TheAtom, but a version of Superman based on his previous portrayal in ''Film/SupermanReturns''.
66* Creator/VictoriaRowell: In ''Series/DiagnosisMurder'', Dr. Bentley has a ContestWinnerCameo on ''Young and the Restless'', and there are frequent references to Bentley's resemblance to Victoria Rowell (who was on both shows).
67* Creator/KurtRussell:
68** Creator/BoomStudios had a crossover between ''ComicBook/BigTroubleInLittleChina'' and ''ComicBook/EscapeFromNewYork'', having Kurt Russell's two characters meeting each other.
69** In Creator/CrossGen's ''John Carpenter's Snake Plissken Chronicles'', Snake teams up with a fisherman called Captain Ron. Named after Russell's character in the [[Film/CaptainRon movie of the same name]]. Sadly this version is an old black man who looks nothing like Kurt Russell.
70* Creator/SheridanSmith: The 2009 UsefulNotes/ComicRelief night included a TalentContest crossover between ''Series/TwoPintsOfLagerAndAPacketOfCrisps'', ''Series/GrownUps'' and ''Series/ComingOfAge'', in which her ''Two Pints'' character, Janet, and her ''Grown Ups'' character, Michelle, perform a duet.
71* Creator/PatrickStewart. Done in reverse, with the official ''ComicBook/XMen''/''Series/StarTrekTheNextGeneration'' crossover ''Planet X'' which featured Captain Picard meeting Professor Xavier, but came out before the first ''Film/XMen1'' movie when Patrick Stewart was obviously not yet cast in the second role. Made even funnier by a character remarking that both share a likeness.
72* Creator/KappeiYamaguchi: ''Manga/RanmaOneHalf''[=/=]Manga/InuYasha. Title characters Ranma and Inuyasha are both voiced by Kappei Yamaguchi and they actually encounter each other semi-officially in an animated promotion for ''It's A Rumic World'',[[note]]A compilation of short works by Creator/RumikoTakahashi; the short used the main characters of her three most famous series: ''Manga/InuYasha, Manga/RanmaOneHalf'', and ''Manga/UruseiYatsura''.[[/note]] Inuyasha even [[LampshadeHanging lampshades this trope]] by demanding to know why Ranma has his voice.
73* Creator/CaseyKasem: On ''WesternAnimation/TheNewScoobyDooMovies'', one episode crossed over with ''The Batman/Superman Hour'' in which Casey Casem voices both Shaggy and Robin. Another episode crossed over with ''WesternAnimation/JosieAndThePussycats'', which featured Casem as both [[ExpyCoexistence Shaggy and Alexander]].
74[[AC:Works with multiple examples:]]
75* ''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''). It's 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.
76* ''VideoGame/DisneyInfinity'':
77** An ad for the game features the game's versions of Jack Sparrow from ''Franchise/PiratesOfTheCaribbean'' and Tonto from ''Film/TheLoneRanger'' meeting each other; the non-computer generated versions of both characters were played by Creator/JohnnyDepp. This also was a subtle DearNegativeReader addressed to the people complaining that Tonto was just an "Indian Jack Sparrow" by showing them side by side to prove that they are not very alike (Sparrow is a LovableRogue and Tonto is ComicallySerious). Shortly before its cancellation, it added Depp's Mad Hatter from ''Film/AliceInWonderland2010'' as well.
78** ''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 Franchise/TheIncredibles were part of the game, Frozone didn't show up with them.
79* ''VideoGame/SuperRobotWars'':
80** ''VideoGame/{{Super Robot Wars Z}}2: Saisei-Hen'' has Ribbons Almark (''Anime/MobileSuitGundam00'') and Amuro Ray (''Anime/MobileSuitGundam'') interacting and eventually fighting each other.
81--->'''Amuro:''' Ribbons! I am nothing like you!\
82'''Ribbons:''' This is the difference between my power and yours.
83** Interaction between two characters: Anytime characters Misato Katsuragi and Amuro Ray show up in the same game together. Why is that so good? Because they're Sailor Moon and Tuxedo Kamen! Actress Creator/KotonoMitsuishi voiced Sailor Moon in ''Anime/SailorMoon'' and also Misato Katsuragi in ''Anime/NeonGenesisEvangelion'', and Creator/ToruFuruya voiced Tuxedo Kamen in ''Sailor Moon'' & Amuro Ray in ''Anime/MobileSuitGundam''.
84** Full Frontal and Char Aznable ''VideoGame/{{Super Robot Wars Z}}3: Jigoku-Hen''. Both characters are voiced by Creator/ShuichiIkeda (Char Aznable of ''Mobile Suit Gundam'' and Full Frontal of ''Mobile Suit Gundam Unicorn''). In fact, Full Frontal even works for Char until the Axis colony drop. Full Frontal is the one who caused it.
85* ''Franchise/SuperSentai'':
86** Creator/KenjiOhba has played Retsu Ichijoji, the titular HenshinHero in ''Series/SpaceSheriffGavan'', and two different Sentai heroes - so naturally, when Gavan [[Film/KaizokuSentaiGokaigerVsSpaceSheriffGavanTheMovie crossed over]] with ''Series/KaizokuSentaiGokaiger'', [[Series/BattleFeverJ Shiro Akebono/Battle Kenya]] and [[Series/DenshiSentaiDenziman Daigoro Oume/Denji Blue]] were along for the ride. Only fanboy Gai can tell them apart (and considers the differences ''obvious''). Funnily, Ohba had performed both his Sentai roles before in ''Gokaiger'': he played Oume in the ''199 Heroes'' movie, and Akebono in the ChristmasEpisode of the series proper.
87** Sadly, Creator/HiroshiMiyauchi has never gotten to do this in a TV series or movie: on the two occasions that ''Series/JAKQDengekitai'' and ''Series/HimitsuSentaiGoranger'' have wound up in the same place, Miyauchi only played his ''JAKQ'' character, Sokichi Banba/Big One, with Akira Shinmei/Aoranger being just one more suited stuntman doing chop-socky in the background. In the ''Let's Go Kamen Rider'' megacrossover, neither Series/KamenRiderV3 ''nor'' [[Series/KaiketsuZubat Zubat]] ever appeared out-of-costume, though both were voiced by him. Still, in-universe, Miyauchi's characters have met a few times now, though only one at a time got what most consider a full appearance. The only time Miyauchi did get to meet himself was in [[https://www.youtube.com/watch?v=BmCKR3UiEJw an ad]] for the video game ''VideoGame/SuperHeroSakusenDaidaruNoYabou'', in which V3 and Zubat appeared in their civilian forms of Shiro Kazami and Ken Hayakawa respectively.

90[[folder:Fandom Examples]]
91* In the ''Series/AdamAdamantLives'' fanfic [[http://archiveofourown.org/works/3999313 "A Romantic Or A Rogue?"]] the villain is a thinly-disguised Nelson Gabriel from ''Radio/TheArchers'' -- who, like Adam's valet Simms, was played by Jack May.
92* ''Series/{{Andromeda}}'' all but canonized the notion that Dylan Hunt is the reincarnation of Hercules of ''Series/HerculesTheLegendaryJourneys''. Portrayed by Kevin Sorbo.
93* ''Series/{{Angel}}'' crossovers:
94** There are fics where cast members from ''Angel'' mistake Zoe from ''Firefly'' for their very own Jasmine. Jasmine and Zoe are played by Creator/GinaTorres.
95** Fics where cast members from ''Angel'' mistake Jayne from ''Firefly'' for Marcus Hamilton. Both played by Creator/AdamBaldwin.
96** Apart from the natural "Booth is a shanshued Angel" fics, there have been a couple of ''Series/{{Bones}}''[=/=]Series/{{Angel}} fics where vampire Angel somehow meets FBI agent Booth. Fans of Creator/DavidBoreanaz write these stories.
97* ''Series/BattlestarGalactica2003'' crossovers:
98** Fic [[http://www.fanfiction.net/s/5531412/1/From_Prometheus_to_12 "From Prometheus to 12"]] plays with the concept that Felix Gaeta (''Battlestar Galactica'') and L (''Manga/DeathNote'') are the same person. Gaeta is played by Alessandro Juliani and L is voiced by him in the English dub.
99** ''Series/{{Firefly}}'' & ''Battlestar Galactica (2003)'': One can only speculate at just what the hell happened to Badger (''Firefly'') who goes from kinda-Cockney crime boss to President of the Colonies in ''Battlestar Galactica (2003)''. Pretty impressive feat. (Both are played by Creator/MarkSheppard.)
100** [[http://archiveofourown.org/works/100760 "Astra Major"]] features naval officer Archie Kennedy from ''Series/HoratioHornblower'' and ace pilot "Apollo" Lee Adama from ''Battlestar Galactica'', both played by Creator/JamieBamber.
101* In ''Lost Ones'', a ''WesternAnimation/Ben10UltimateAlien'' crossover with the DC Universe, Gwen fights Slade, who remarks that [[WesternAnimation/TeenTitans2003 "You remind me of someone I knew a long time ago, she was a lot like you. You even sound like her too...let's just say that someone with the power of Geokinesis used to work for me."]] Considering the fact that Creator/AshleyJohnson plays both Gwen and Terra, it's pretty fun, though they haven't met each other yet.
102* Crossing ''Franchise/BillAndTed'' with ''Franchise/TheMatrix'' due to Creator/KeanuReeves being in both isn't unheard of. In particular is ''[[http://www.billandted.org/stories/masakochan/matrixend.html An Alternate Ending to Matrix Revolutions]]'', with a side of MindScrew.
103* In [[http://hermit.org/Blakes7/Library/DispStor.cgi?SR=59649&ST=0002&COUNT "Rebel Quartet,"]] a ''Series/BlakesSeven'' story, Orac meddles with the teleport and fetches back not one Blake, but four (all played by Gareth Thomas). There's Blake, the Rev. Griffiths (''Literature/HowGreenWasMyValley''), resistance leader Owen Edwards (''The Knights of God''), and magician Blaze (''Merlin: the Quest Begins''), who promptly sets Orac on fire. All four are rebels against oppression, none of them can agree on anything, and Avon, who hasn't been bothered in weeks, has never been so content in all his life.
104* ''Series/BuffyTheVampireSlayer'' crossovers:
105** ''Buffy the Vampire Slayer'' and ''Series/VeronicaMars'' share enough actors to make an arsenal of this, albeit most of them in minor roles in the latter.
106** The relationships between Spike (''Buffy the Vampire Slayer'') and Captain John Hart (''Series/{{Torchwood}}'') who are both portrayed by Creator/JamesMarsters really run the gamut from being the same person to being enemies, friends, lovers or basically anything else you can imagine.
107** At least one Anthony Head doppelgänger ''Series/{{Merlin|2008}}'' [=/=]'' Buffy the Vampire Slayer'' fic exists with Uther and Giles meeting. Both roles are courtesy of Creator/AnthonyHead.
108** The first "Echo is Faith" fics started showing up less than 24 hours after ''Series/{{Dollhouse}}'' was announced -- i.e., more than a year before the first episode aired. Creator/ElizaDushku is an actress portraying Faith Lehane on ''Buffy'' and ''Angel'' and Echo on ''Dollhouse''. Creator/AmyAcker getting cast helped, too, as she appeared on ''Angel'' as well.
109** ''Buffy the Vampire Slayer''/''Series/{{Firefly}}'' crossovers where Xander initially panics upon meeting Mal Reynolds because of the latter's resemblance to Caleb. (Caleb and Mal are both portrayed by Creator/NathanFillion.)
110** There are fics where the characters from ''Buffy'' mistake the friendly and decent Richard Castle of ''Series/{{Castle|2009}}'' for the psychotic Caleb. Both Caleb and Castle are played by Nathan Fillion. Unlike nice guy Castle, Caleb is a sadistic sociopath.
111%% * ''Manga/BusoRenkin'' fanfic writers like to crossover with ''Manga/RurouniKenshin'', usually making Kazuki into Kenshin's (great-great-grand)son.
112%% Who is the shared voice actor?
113%%
114* ''Series/{{Castle|2009}}'' crossovers:
115** It's popular in fan-works to suggest that Richard Castle from ''Castle'' is either a distant ancestor of or is in some TimeyWimeyBall-way connected to ''Series/{{Firefly}}'''s Malcolm Reynolds. Both Richard Castle and Mal Reynolds are creations of Creator/NathanFillion.
116** There are fics where the characters from ''Buffy'' mistake the friendly Castle for the psychotic Caleb. HilarityEnsues. Both Caleb and Castle are played by Nathan Fillion. Castle is a lovable, teasing nice guy, while Caleb is a sadistic sociopath with a pathological hatred of women.
117* ''Series/{{Chuck}}'' and ''Series/WhiteCollar'' often crossover in fan fics. The premise is usually Neal was an alias of Bryce's he started using again after faking his death for the second season. Or they're twins. Both Caffrey (''White Collar'') and Bryce Larkin (''Chuck'') are played by Matthew Bomer.
118* ''Series/{{Community}}'' fics that fancy bringing the angst and Hurt/Comfort on, one option is to imagine that Britta, played by Creator/GillianJacobs, is the same character that Jacobs plays in the movie ''Gardens of the Night'', a dark drama about a young woman who is kidnapped as a child and forced into prostitution. It helps that Britta is implied at times to have had a rough childhood with possible molestation involved, albeit usually played for BlackComedy instead of drama.
119* ''Series/CriminalMinds'' crossovers:
120** Ever wonder why there's a ''Criminal Minds''/''Series/DharmaAndGreg'' [[http://www.fanfiction.net/Dharma_Greg_and_Criminal_Minds_Crossovers/1375/2362/ crossover section over at Fanfiction.net]]? Because Thomas Gibson was in both shows, inspiring fics where Agent Hotchner (a.k.a. "Hotch") of ''Criminal Minds'' is actually Greg from ''Dharma&Greg'' in disguise and vice versa.
121** 'Being each other in disguise plot' has happened with Reid's mother (''Series/CriminalMinds''), Sue Sylvester (''Series/{{Glee}}'') and Sam's mother (''Series/ICarly '') due to Jane Lynch playing all three characters.
122* There is a significant number of crossovers between ''Series/DarkAngel'' and ''Series/{{NCIS}}'' (because of shared actor Creator/MichaelWeatherly) where Tony [=DiNozzo=] becomes Logan Cale or vice versa. Science magic is usually invoked to explain the timeline and/or the character aging in reverse.
123* ''Series/DoctorWho'' crossovers:
124%% ** 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.
125%% ** 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/AbsolutePowerBBC Charles Prentiss]].
126** John Elliott wrote [[http://www.whofic.com/viewstory.php?sid=43267 "All I Ask"]], in which the Fourth Doctor (Creator/TomBaker) is confronted by an incarnation of Captain Redbeard Rum from ''Series/{{Blackadder}}''.
127** 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 part of UsefulNotes/ComicRelief.
128%% ** 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]].
129** "[[http://archiveofourown.org/works/7262914/chapters/16490440 Countess of Confusion, Duchess of Disorder]]" is an Echo!Clara[=/=]''Literature/TheScarletPimpernel'' crossover in which an echo of Creator/RichardEGrant's Great Intelligence is [[Series/TheScarletPimpernel the dark-haired, widowed Sir Percy]], who is not the ''real'' Sir Percy.
130%% ** 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.
131%% ** 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.
132** ** There are umpteen ''Series/{{Life On Mars|2006}}'' fics that reveal that Sam Tyler is in fact... the Master from ''Doctor Who''. Both played by John Simm.
133%%
134%% ** Prevalent in ''Fanfic/ThisTimeRound'' -- not mentioned on the work page, though, please provide more context
135%%
136* ''Series/DrakeAndJosh'' / ''Series/ICarly'' crossover:
137** In fic ''[[http://www.fanfiction.net/s/8532906/1/iFightCrimeWithVictorious iFight Crime With Victorious]]'' when two of Creator/MirandaCosgrove's characters, Carly Shay (''[=iCarly=]'') and Megan Parker (''Drake & Josh''), meet thanks to Megan's precognitive power. This serves as a plot point since Megan thinks that [[spoiler:she is seeing herself in her visions of the future, but the person in them is actually Carly]]. Megan When they meet, Megan comments on how much their personalities contrast despite their similar appearance.
138** CrossoverShip: There are fics that ship Carly (''[=iCarly=]'') and Megan (''Drake & Josh''). A few people go so far as to add Summer Hathaway from ''Film/SchoolOfRock'', into a Creator/MirandaCosgrove Doppelganger OT3. Triplet Doppelganger ScrewYourself-like ship is even better than TwinThreesomeFantasy.
139* There is a ''WebVideo/DoctorHorriblesSingAlongBlog''/''Series/HowIMetYourMother'' crossfic where Barney Stinson [[ScrewYourself seduces]] Dr. Horrible. There are also countless ''Doctor Horrible's Sing-Along Blog''/''How I Met Your Mother'' crossovers where Barney secretly is Dr Horrible... The fact the gang were looking for Doppelgängers was a subplot for a season of HIMYM or so helps.
140* ''Series/{{Elementary}}'' & ''Film/KillBill'': There are a few ''Elementary'' and ''Kill Bill'' crossover fanworks because Joan of ''Elementary'' and O-Ren of ''Kill Bill'' share the same actress Creator/LucyLiu.
141* ''Series/{{EUReKA}}'' & ''Series/{{Warehouse 13}}'': It's not uncommon for fans of ''[=EUReKA=]'' and ''[=Warehouse 13=]'' to say that Carl Carlson and Artie Nielsen are the same person. Both are played by Saul Rubinek. It helps that both shows are canonically in the same SharedUniverse.
142* ''Series/{{Firefly}}'':
143** ''Firefly'' & ''Series/BattlestarGalactica2003'': One can only speculate at just what the hell happened to Badger (''Firefly'') once the crew left him to make him straighten up, learn the law and start ste-- no, wait, that one's already covered. Still, going from kinda-Cockney crime boss to President of the Colonies (''Battlestar Galactica''), pretty impressive feat. Both are Creator/MarkSheppard's roles.
144** There are a number of ''Firefly''/''Series/TerminatorTheSarahConnorChronicles'' crossovers that usually feature Cameron being mistaken for River, often with Alliance soldiers getting curb stomped. Both portrayed by Creator/SummerGlau.
145** ''Buffy the Vampire Slayer''/''Firefly'' crossovers where Xander initially panics upon meeting Mal Reynolds because of the latter's resemblance to psychotic Caleb. Mal and Caleb are Nathan Fillion's roles.
146** It's popular in fan-works to suggest that Richard Castle from ''Series/{{Castle|2009}}'' is either a distant ancestor of or is in some TimeyWimeyBall-way connected to ''Firefly'''s Malcolm Reynolds. Both played by Nathan Fillion.
147** There are fics where Zoe from ''Firefly'' is mistaken for Jasmine by characters from ''Angel''. Jasmine and Zoe are played by Gina Torres.
148** Fics where cast members from ''Angel'' mistake Jayne from ''Firefly'' for Marcus Hamilton. Both played by Adam Baldwin.
149* Prior to ''WesternAnimation/Frozen2013'''s Elsa, Creator/IdinaMenzel's most popular role was Elphaba in ''Theatre/{{Wicked}}''. Naturally fans of both have made many crossovers, especially considering how similar Elsa and Elphaba are.
150* There is at least one ''Manga/FullmetalAlchemist''[=/=]''Manga/OuranHighSchoolHostClub'' crossover fan fic which exists purely because the English dubs of both animes have the same voice cast.
151* ''Series/GameOfThrones'' & ''Literature/ASongOfIceAndFire'' & real life: In ''Fanfic/SeanBeanSavesWesteros'', [[RealPersonFic "real life"]] Creator/SeanBean gets transported to Westeros soon after Season 1 of ''Game of Thrones'' wraps up filming, and takes the place of Ned Stark.
152* Aside from Xanatos and Riker, ''WesternAnimation/{{Gargoyles}}'' and ''Series/StarTrekTheNextGeneration'' shared Marina Sirtis, Michael Dorn, Brent Spiner, Le Var Burton, and Colm Meaney. Cameos from other ''Star Trek'' series included Kate Mulgrew as fairy queen Titania (often disguised as a human scientist) and Nichelle Nichols as the female lead's mother. Crossovers milked this for all it was worth.
153* The ''Film/HarryPotter'' and ''Film/{{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.
154* ''Series/{{Heroes}}'' crossovers:
155** ''Heroes'' & ''Series/{{Scrubs}}'' crossover: Masi Oka portrays lab-guy Franklin on ''Scrubs'' and also portrays Hiro Nakamura on ''Heroes'', a fact picked up on in one or two fanworks.
156** Claude Rains from ''Heroes'' being secretly the Ninth Doctor of ''Series/DoctorWho'' was a very popular idea for a time because of Christopher Eccleston who played both characters.
157* ''Series/{{Highlander}}'' crossovers:
158** Methos, the legendary oldest Immortal, gets around a lot in general. Played by Creator/PeterWingfield.
159** ''Highlander'' & ''Series/TheSentinel'':
160*** Captain Simon Banks of ''The Sentinel'' has been mistaken for the Immortal Carl Robinson. Both are the creations of actor Bruce A. Young.
161*** A certain Really Old Guy of ''Highlander'' either gets mistaken for or actually is a certain serial killer of ''The Sentinel''.
162** Philip Akin appeared as a regular in the first season of ''Series/WarOfTheWorlds1988'', Adrian Paul in the second. Since both actors also appeared in ''Highlander: The Series'', crossovers make up a sizable proportion of ''War of the Worlds'' fanfic, either with Kincaid as a cover identity for [=Macleod=] or one being mistaken for the other.
163* ''VisualNovel/HigurashiWhenTheyCry'' and ''Franchise/LyricalNanoha''? Since Rika and Nanoha share a voice actress Creator/YukariTamura, there have been fan videos that involve the two.
164* Inverted in the ''Series/HogansHeroes'' story ''[[http://www.fanfiction.net/s/7222614/1/Return-of-the-Informer Return of the Informer]]'': the author takes one recurring actor playing seven different characters, and has these characters being one and only hapless guy (the aforementioned informer, now defected to the Allies and turned spy against his will). It's frequently hilarious (especially the "Oh no - him again!?" reactions of the main cast) and often quite touching.
165* ''Series/HoratioHornblower'':
166** [[http://archiveofourown.org/works/100760 "Astra Major"]] is a short story written by [=FlirtyFroggy=], an avid Bamber Bunnny. The fic features Archie Kennedy from ''Horatio Hornblower'' and "Apollo" Lee Adama from ''Series/BattlestarGalactica2003'', both played by Creator/JamieBamber. His fans told him at one convention that they liked to live in a world where Archie didn't die and asked him about his theory on how Archie had survived. Mr Bamber replied: "When they carried his corpse away, aliens came down and resuscitated him, and now he's living on Astra Major in some other galaxy. And maybe Lee Adama will come across him, and asks: 'What the hell is going on with you, Arch?'" This answer inspired the author to write her story.
167** There are quite a few fan fics featuring Midshipman (Lieutenant) Archie Kennedy from ''Horatio Hornblower'' and Lord Tony Dewhurst from ''Series/TheScarletPimpernel'', both portrayed by then-25-year-old Jamie Bamber. It seems to be a particularly good fit because both series (first episodes) are set in 1793. Several stories make those two [[TheCutie Cuties]] cousins and their identical looks are explained as uncanny family resemblance. WordOfGod has it that Archie is the third son of a Scottish Lord and Tony is a British aristocrat as well, so it all fits together. The stories tend to be FixFic because the pattern of ChronicallyKilledActor started to appear. [[http://archieology101.tripod.com/backgrounds.htm#cousins Here]] is a list of cousin stories from ''Archieology 101''. [[note]]For instance, see [[http://www.hhfic.com/castle.html "Castle Out Of Check"]] by Jan Lindner (GenFic, FixFic). [[http://web.archive.org/web/20061017130124/http://www.io.com/~cortese/stories/show.cgi?fandom=hornblower&filename=doppel.txt "Doppelgänger"]] by Janis Cortese (SlashFic, explicit, bitter-sweet). In this story, Horatio meets Tony when Archie is lost and presumed dead. Hornblower's shattered by the resemblance but Archie and Tony don't actually meet. [[/note]]
168** [[https://archiveofourown.org/works/1029250/chapters/2050010 "Declassified"]] is a fic that uses concept of Immortals from ''Series/{{Highlander}}'' and takes characters from ''Horatio Hornblower'' and ''Series/LawAndOrderUK''. Matt Devlin of ''Law and Order UK'' inexplicably recovers from the fatal bullet wounds he received at the end of the episode "Deal" and is forced to admit to his best friend/partner Ronnie and his crush Alesha Phillips that he's Immortal, thus revealing that he IS Archie Kennedy. So there is only one person, but they are two characters played by Jamie Bamber.
169* ''Series/{{House}}''/''Series/JeevesAndWooster'' crossovers: Interestingly subverted in a few ''House'' fanfics that somehow add Jeeves to the mix instead of Bertie. Hugh Laurie plays both dr. House and Bertie; Stephen Fry portrays Jeeves. Fans apparently believe these two belong together.
170* A fanfic that crossed over ''Series/{{JAG}}'' with ''Series/ThePretender'' had Lt. Cmdr. Rabb mistake Miss Parker for his former partner Lt. Caitlin Pike. Both Miss Parker and Lt. Pike were played by Andrea Parker.
171* In [[http://community.livejournal.com/indeedsir/506390.html?thread=7493142#t7493142 "Jeeves and the Evil Twin"]], a ''Series/JeevesAndWooster'' fanfic in which Jeeves comes home from vacation to find that Jack Dalliard (one of Creator/StephenFry's recurring characters in ''Series/ABitOfFryAndLaurie'') has been not only impersonating him but abusing and raping Bertie.
172* A popular crossover is ''Series/{{Leverage}}'' and ''Series/TheLibrarians2014'', since both have Creator/ChristianKane in the main cast. Some have Jacob Stone be Eliot Spencer's brother.
173* There are umptynine ''Series/{{Life On Mars|2006}}'' fics that reveal that Sam Tyler is in fact... the Master from ''Series/DoctorWho''. John Simm's fans are responsible for those.
174* ''Fanfic/TheOfficialFanfictionUniversityOfMiddleEarth'' contains a chapter where the "teachers" (read: cast of ''Film/TheLordOfTheRings'') were all replaced by other characters played by the same actors. Wasn't that the fault of the original two WebOriginal/ProtectorsOfThePlotContinuum, who were visiting? Or was that a different event?
175* Marvel and DC universe crossovers: Ryan Reynolds and Ben Affleck played characters in both the Marvel and DC universes. Reynolds plays Hal Jordan/Green Lantern in the DC universe with Ben Affleck's Bruce Wayne/Batman. In Marvel, Reynolds plays Wade Wilson/Deadpool with Ben Affleck's Matt Murdock/Daredevil. Many Marvel/DC fan-created crossovers play off this.
176* The Franchise/MarvelCinematicUniverse and ''Film/TheMartian'' have gotten their fair share of crossovers likely partially due to there being multiple actors who appear in both the MCU and ''The Martian''. The means of crossing over has varied, from [[http://archiveofourown.org/works/6804808/chapters/15539422 Steve Rogers waking up a few decades late]] to [[http://archiveofourown.org/works/10027490 Dr. Beck being one of]] [[http://archiveofourown.org/works/10525005 Bucky Barnes's descendants]] to [[http://archiveofourown.org/works/4684565/chapters/18225943 Dr. Beck being suspected of being the Winter Soldier]].
177* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', the Season 2 villain Discord is inspired by the RealityWarper Q from ''Series/StarTrekTheNextGeneration'', even being played by the same actor, John de Lancie. There have since been numerous works of fan art and fan fiction that show that Discord ''is'' Q, usually by way of the TNG Enterprise crew visiting Equestria.
178* One short fanfic had ''Series/{{NCIS}}''[='=]s medical examiner Dr. Donald Mallard, better known as Ducky, mistake ''Series/RizzoliAndIsles''[='=] medical examiner Dr. Maura Isles for his friend Kate (he was involved in a small accident). It can be assumed to be Kate Todd from the first two seasons because Kate just happens to be played by the same actress who plays one of the title characters from Rizzoli & Isles. The actress's name is Sasha Alexander. [[http://www.fanfiction.net/s/6162024/1/A_Resemblance Any guesses?]] Not the only thing involving Ducky Mallard, played by David [=McCallum=]; there are fics out there of him either being related to or ''being'' Illya Kuryakin from ''Series/TheManFromUncle'', [=McCallum=]'s breakout role. Which is kinda weird since an ActorAllusion line early in the seris made reference to Ducky's resemblance to Illya.
179* ''Manga/RanmaOneHalf'' crossovers:
180** ''Ranma One Half'' crosses over with ''Manga/AhMyGoddess'', it is inevitable that Belldandy and Kasumi (both sweet, innocent, domestic characters voiced by Creator/KikukoInoue) sit down to trade recipes, or better yet, collaborate on a meal.
181** In Chris Davies' MegaCrossover ''Together Again 1996 Chapter'', it's revealed that Kasumi is a reincarnated inhabitant of the [[Anime/SailorMoon Silver Millennium]] with some very strong, very negative opinions about "the monsters who call themselves gods" (to use her words from the story), and who is outright hostile to Belldandy. However, they seem to get along ''much'' better in another story in that series, ''Together Again 2937 Chapter''.
182** There is at least one ''Ranma'' fanfic crossing over with ''Manga/MagicKnightRayearth'', on the basis that Hikaru Shidou looks like Girl-type Ranma.
183** Plenty of fanfics involve Lina Inverse from ''{{Literature/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.
184** The some-odd ''Ranma''[=/=]''Manga/InuYasha'' crossovers where Ranma invariably turns out to be Inuyasha's reincarnation. They're up in the article itself for a reason. In addition, the two actually encountered each other semi-officially in an animated promotion for ''It's A Rumic World,''[[note]]A compilation of short works by Creator/RumikoTakahashi; the short used the main characters of her three most famous series: ''Manga/InuYasha, Manga/RanmaOneHalf'', and ''Manga/UruseiYatsura''.[[/note]] which once provided the page illustration. Inuyasha even [[LampshadeHanging lampshades this trope]] by demanding to know [[Creator/KappeiYamaguchi why Ranma has his voice]].
185* ''Series/{{Sherlock}}'' crossovers:
186** It can be rather difficult to watch ''Series/MyLifeInFilm'' and not see Jones as ''Series/{{Sherlock}}'''s Jim Moriarty. Especially when he starts talking about burying people in back gardens. Both Jones and Moriarty are played by Andrew Scott.
187** This trend has grown incredibly popular in the ''Sherlock'' fandom, with actors Martin Freeman being in ''Film/TheHobbit'' and Creator/BenedictCumberbatch acting in ''Film/StarTrekIntoDarkness''.
188** There are a ton of ''Sherlock'' crossovers with ''Radio/CabinPressure'', also starring Cumberbatch; his character Martin Crieff is often revealed to be a third Holmes brother.
189** Cumberbatch has voiced Smaug in the second ''Hobbit'' film. Now there's a proposal for an imagination exercise: Holmes meets Smaug.
190* ''Series/StargateSG1'':
191** ''Stargate SG-1'' and ''Series/{{MacGyver|1985}}''. There are too many of these fics, far too many [=JackGuyvers=]. Creator/RichardDeanAnderson portrays both [=MacGyver=] and Colonel Jack O'Neil. Even the cast got in on it once, with the famous [[https://www.youtube.com/watch?v=Oo8mePgx4yw "Trapped on a glacier with McGuyver!"]] outtake.
192** "What if Crichton met Mitchell" has been done ''many'' times. There are way too many Starscape fics, also (but not so often) called Fargate. Robert Benedict Browder is an actor known for his roles as John Crichton in ''Series/{{Farscape}}'' and Cameron Mitchell in ''Stargate SG-1''. Even the SG-1 series itself did a Farscape parody (interestingly, Mitchell and Vala do ''not'' take the roles their actors did in the actual ''Farscape'').
193* There now exists [[FandomSpecificPlot an entire genre]] of ''Film/StarTrek2009'' fiction where Bones is actually John "Reaper" Grimm from ''VideoGame/{{Doom}}'', or at the very least, his something-great grandson. Creator/KarlUrban's fans are responsible.
194* ''Series/{{Supernatural}}'' crossovers:
195** There are several ''Supernatural'' and ''Series/DarkAngel'' crossover fics. Their ubiquity isn't surprising, as Creator/JensenAckles's characters in ''Dark Angel'', the twins Ben and Alec, were genetically engineered, and thus could conceivably be clones of Dean from ''Supernatural'' as an ObviousCrossoverMethod. In light of that, and the TwinThreesomeFantasy trope, it was probably inevitable. However, ''Dark Angel'' is set TwentyMinutesIntoTheFuture. So, if Dean isn't going to be in his forties, either time travel or alteration to the canonical timeframe is necessary in order for the characters to interact at their onscreen ages (at the end of ''Dark Angel'' it's 2021 and Ben and Alec are roughly 21 or 22 - Project Manticore wasn't big on birthdays - and at the beginning of ''Supernatural'' it's 2005 and Dean is 26). Or heck, they could be parallel universes. One form of fic which is surprisingly common despite messing '''heavily''' with the timeline is the story in which Alec left Seattle after "Freak Nation" and became Dean.
196*** With ''Supernatural'' turning out to be such a LongRunner, the age thing is no longer such an issue. As of 2019-2021, Dean now ''is'' in his forties on the show and we're in the timeframe that ''Dark Angel'' was set (albeit slightly less dystopian despite that we got Covid instead of the Pulse).
197** There is a small niche of fan fics devoted to crossovers between ''Supernatural'' and ''Series/GilmoreGirls'' which writers find doubly fun to play with because ''Gilmore Girls'' character Dean Forester is also played by ''Supernatural'''s Creator/JaredPadalecki and happens to share a name with Padalecki's current character's brother, Dean Winchester. Dean Forester lives the "apple pie" life Sam Winchester always wanted so theories abound that during the period of pre-series where Sam ran away from home, he actually went to Stars Hollow and lived with a family while using his brother's name as an alias.
198** 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 superpowered beings and strange occurrences.

210[[folder:Fandom: Multiple-Work References]]
211* Creator/OrlandoBloom: There are fics out there about Legolas (''Film/TheLordOfTheRings'') meeting Will Turner (''Franchise/PiratesOfTheCaribbean '') and/or Balian (''Film/KingdomOfHeaven'') and/or Orlando Bloom himself.
212* Creator/HelenaBonhamCarter: Bellatrix Lestrange from ''Film/HarryPotter'' meets Mrs. Lovett of ''Film/SweeneyToddTheDemonBarberOfFleetStreet'' and The Red Queen from ''Film/AliceInWonderland2010''. All three eerie creations are courtesy of Helena Bonham-Carter.
213* Creator/RaymondBurr: "[[https://www.pjfarmer.com/woldnewton/Wheels.pdf Wheels Within Wheels]]" is an ''Series/Ironside1967''-centered MassiveMultiplayerCrossover in which L.B. Jeffries from ''Film/RearWindow'' mistakes Ironside for Lars Thorwald, who in turn was killed in prison when someone mistook him for Rick Coyle, the gangster Burr played in ''Film/RawDeal1948''. Ironside also mentions that Steve Martin from ''Film/GodzillaKingOfTheMonsters1956'' is his cousin, and rails against a lawyer named [[Franchise/PerryMason Mason]] (although the similarity isn't mentioned in that case). In addition, the motive for Jeffries' murder turns out to be [[spoiler: he was mistaken for another Creator/JamesStewart character: ''Film/ItsAWonderfulLife'''s George Bailey]].
214* 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/DollarsTrilogy 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:
215--> Legendary film director [[Film/WhiteHunterBlackHeart John Wilson]] [...] New Orleans police detective [[Film/{{Tightrope}} Wes Block]] [...] World War II hero Lieutenant [[Film/KellysHeroes Kelly]], popular DJ [[Film/PlayMistyForMe Dave Garver]], Inspector [[Film/DirtyHarry "Dirty" Harry Callahan]], art history professor and photographer [[Film/TheBridgesOfMadisonCounty Robert Kincaid]] (rumored to have worked secretly for the government under the code name [[Film/TheEigerSanction Jonathan Hemlock]]), bare-knuckle fighter [[Film/EveryWhichWayButLoose Philo Beddoe]], fighter pilot [[Film/{{Firefox}} Mitchell Gant]], Gunnery Sergeant [[Film/HeartbreakRidge Tom Highway]], modern-day bounty hunter [[Film/PinkCadillac Tommy Nowak]], Secret Service agent [[Film/InTheLineOfFire Frank Horrigan]], and astronaut [[Film/SpaceCowboys Frank Corvin]] [...] country singer [[Film/HonkyTonkMan Red Stovall]] and [[Film/EscapeFromAlcatraz Frank Morris]], one of the only three men who ever escaped Alcatraz. Frank would later operate as a master thief under such aliases as [[Film/ThunderboltAndLightfoot Thunderbolt]] and [[Film/AbsolutePower1997 Luther Whitney]] [...] Arizona deputy [[Film/CoogansBluff Walt Coogan]] and his cousin [[Film/TheGauntlet Ben Shockley]].
216* Creator/HarrisonFord has such a career with fingers in the pies of so many fandoms that he is almost a too-obvious go-to person for this fanfic trope. What happens when Literature/JackRyan tries to rescue the president aboard Film/AirForceOne? What if [[Film/BladeRunner Lieutenant Deckard]] is chasing Film/TheFugitive? What if Franchise/IndianaJones found the wreckage of the ''[[Franchise/StarWars Millennium Falcon]]'' in the Northwest United States while looking for Bigfoot? (That one is an ''official'', non-canon [[ComicBook/StarWarsTales comic story]], mind you.) And most importantly, [[UltimateShowdownOfUltimateDestiny who would win in a fight?]]
217* Creator/AnthonyMichaelHall: The Wold Newton article ''[[https://www.pjfarmer.com/secret/contributors/luthor-frankenstein.html Luthors meet the Frankensteins in Shermer, Illinois]]'', which ties multiple Creator/JohnHughes films together, proposes that [[Film/SixteenCandles Farmer Ted]], [[Film/TheBreakfastClub Bryan Johnson]], and [[Film/WeirdScience Gary Wallace]] are three of SeparatedAtBirth quads.
218* Creator/JohnKapelos: The same article also suggests that Rudy, Carl and Dino are the same man; employed to watch the three boys in case their Frankenstein heritage comes through (as it did in Gary's case). He later gets called away by the organisation he works for, and is instead assigned to watch over a FriendlyNeighbourhoodVampire named [[Series/ForeverKnight Nick Knight]] under the name Don Schanke.
219* Creator/KotonoMitsuishi, a voice actress, is a target of frequent fic speculation for her incredibly broad portfolio of roles that offers a vast range of possibilities: imagine, if you will, an intersection of any two or more of those roles: Misato Katsuragi (''Anime/NeonGenesisEvangelion''), Mink (''Manga/DragonHalf''), Usagi Tsukino (''Anime/SailorMoon''), Excel Excel (''Anime/ExcelSaga''), Christie (''VideoGame/DeadOrAlive''), Murrue Ramius (''Anime/MobileSuitGundamSeedDestiny''), Cathy Taymor (''Anime/KaleidoStar''), Gracia Hughes (''Manga/FullMetalAlchemist''), Kagura Soma (''Manga/FruitsBasket''), Boa Hancock (''Manga/OnePiece''), Mireille Bouquet (''Anime/{{Noir}}''), Juri Arisugawa (''Anime/RevolutionaryGirlUtena''), Ebichu (''Anime/OruchubanEbichu'') and Birdy Cephon Altirra (''Manga/BirdyTheMighty'') -- just to name a ''few''.
220* Creator/PedroPascal: His portrayals of both Din Djarin on ''Series/TheMandalorian'' and Joel Miller on ''Series/{{The Last of Us|2023}}'' inspire several fanart of these two {{Papa Wol|f}}ves and their wards meeting each other.
221* Creator/ZacharyQuinto: There is a [[http://www.getphpbb.com/phpbb/viewtopic.php?t=3676&mforum=sarmy fanfic]] on Sarmy [[note]]a portmanteau for Sylar's army[[/note]], a Sylar and Zachary Quinto fansite, which crosses almost every role Zachary Quinto has ever played. Sylar from ''Series/{{Heroes}}'', Spock from ''Film/StarTrek2009'', Sasan from ''So [=noTORIous=]'', Adam Kaufner from ''Series/TwentyFour'', and tons of guest appearances feature in the fic.
222* Creator/JemmaRedgrave fans have a habit of theorizing that [[Series/DoctorWho Kate Stewart]] and [[Series/HolbyCity Bernie Wolfe]] are related -- usually as twins, sisters, or cousins. As a result there are a number of fanfics running around to the tune of this trope. (It doesn't help that the ''Holby'' writers have admitted that they cast Jemma after seeing her performance on ''Who'', and that Kate's characterisation somewhat inspired Bernie's.)
223* Creator/NormanReedus' two most famous characters are Murphy [=MacManus=] in ''Film/TheBoondockSaints'' and Daryl Dixon on ''Series/TheWalkingDead2010''. There are over 70 ''Walking Dead''/''Boondock Saints'' [[http://www.fanfiction.net/Boondock-Saints_and_Walking-Dead_Crossovers/1954/7763/ crossover fics]] on Website/FanfictionDotNet, making it the most common crossover for the ''Boondock Saints'' fandom by far and the third most common for the ''Walking Dead'' fandom.[[note]]There are 110 ''Franchise/HarryPotter''[='=]''Walking Dead'' crossovers and 88 ''Supernatural''/''Walking Dead'' crossovers, but then again, ''Harry Potter'' and ''Supernatural'' crossovers are popular with just about ''every'' "genre" film or series. ''Supernatural'' and ''Harry Potter'' crossovers are also the second and third most common for ''The Boondock Saints'', at thirty and eight respectively.[[/note]] [[ContrivedCoincidence Coincidence?]]
224* Creator/MollyRingwald: The "Creator/JohnHughes films in Wold Newton" article ''[[https://www.pjfarmer.com/secret/contributors/luthor-frankenstein.html Luthors meet the Frankensteins in Shermer, Illinois]]'', referenced above, also proposes that [[Film/SixteenCandles Sam Baker]], [[Film/TheBreakfastClub Claire Standish]] and [[Film/PrettyInPink Andie Walsh]] are SeparatedAtBirth triplets.
225* Creator/WilliamShatner: Bringing this trope to new extremes, there's ''Literature/{{Shatnerquake}}'', where every single character that William Shatner has ever played comes along to whale on the man himself.
