->'''Homer''': Networks like animation because they don't have to pay the actors squat!\\
'''Ned''' ''(voiced by Karl Weidergott instead of Creator/HarryShearer)'': Plus, they can replace them and no one can tell the diddly-ifference.
-->-- ''WesternAnimation/TheSimpsons''

This trope is very prone to happening in animation (both Western and Eastern), and also less obvious - depending on how good the new voice is at impersonating the old one. Of course, money/budget reasons isn't the only factor behind replacing one voice actor with another, as the following examples show.

* ''WesternAnimation/OneHundredAndOneDalmatianStreet'' has 2 cases, both only for 1 episode.
** Big Fee is normally voiced by Pixie Davies. However, in The Nose Job, she was voiced by series regular Aimee-Ffion Edwards.
** Dorothy was voiced by Agnes Peacock in the first short, "Merry Pups". She was replaced by Margot Powell for the series proper.
** In the Italian dub, quite a few characters have been replaced. Alessio De Filippis voiced Dylan for the first 6 episodes before being replaced by Daniele Raffaeli; in turn, Raffaeli voiced Dante for the first 6 episodes before being recast by Daniele Giuliani. Dawkins is voiced interchangeably by Mattia Moresco and Alessio Puccio. Da Vinci beganout being voiced by Corini (also Dimitri 3), but was replaced by Silvia Barone after episode 5. Finally, both Hansel and Constantin had different voice actors earlier on but were replaced.
** The Danish dub has also replaced a bunch of characters, which is especially notable because there are only 9 actors. The only main characters to have stayed so far are Dylan, Dolly, Dawkins, Diesel, Dorothy, Dizzy, Deepak, Delgado, DJ, and the Dimitri Trio.
** The Polish dub has had Da Vinci, Diesel and Hunter De Vil switch actors.
** Brazilian Portuguese had Da Vinci switch actors after she was changed from a boy to a girl in the dub.
** The Latin American Spanish replaced Hansel for no discernible reason.
* ''[[WesternAnimation/OneHundredAndOneDalmatians 101 Dalmatians: The Series]]'':
** Lucky frequently switched off from being voiced by Pamela Segall-Adlon and Debi Mae West (Possibly the latter was used when the former wasn't available.)
** Tress [=MacNeille=] played Cruella in the episode "Close But No Cigar" instead of April Winchell. She also played Cruella ''very'' briefly in "The Fungus Among Us" for one scene (April Winchell played her for the remainder of the episode).
** April Winchell voiced Princess in "Shake, Rattle, and Woof" instead of Cree Summer.
** For Whizzer's first speaking appearance in "Purred It Through The Grapevine" (airing order-wise), he was voiced by Pamela Adlon. When he made his next speaking appearance in "Love 'Em and Flea 'Em", he was played by Christine Cavanaugh, who would play him for the rest of the series.
** In a few episodes such as "Roll Out The Pork Barrel", Jasper was voiced by Jeff Bennett instead of Michael [=McKean=].
* ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' had a few cases of characters being recast.
** King Goobot and Ooblar were voiced by Creator/PatrickStewart and Creator/MartinShort in the PilotMovie ''WesternAnimation/JimmyNeutronBoyGenius'', while their appearances in the series had S. Scott Bullock and Paul Greenberg reprise their roles as the characters from the original 13-minute pilot ''Runaway Rocketboy''.
** Another case of a character being voiced by a different actor from the movie is Sheen's dad Mr. Estevez, who was voiced in the series by Creator/JoeLala instead of Creator/CarlosAlazraqui.
** Retroville's mayor was voiced by Mark [=DeCarlo=] in "Normal Boy" and by Creator/{{Jim Cummings|1952}} in every subsequent episode where he spoke.
** Creator/MauriceLaMarche originally voiced both Zix and Tee of the alien bandit trio, but starting with "The Incredible Shrinking Town", Tee was instead voiced by Creator/KevinMichaelRichardson.
* Almost the entire cast for ''WesternAnimation/{{Aladdin}}'' reprised their roles for the sequels and TV series with the exceptions of Creator/RobinWilliams as the Genie who was replaced by Creator/DanCastellaneta and the Sultan who was voiced by Douglas Seale in the original and was replaced by Val Bettin in the sequels, though Williams was convinced to return for ''WesternAnimation/AladdinAndTheKingOfThieves''.
* ''WesternAnimation/AlphaAndOmega'': All seven sequels replaced the '''entire''' cast from the first film, notably Creator/HaydenPanettiere and Creator/JustinLong were replaced by Creator/KateHiggins and Creator/BenDiskin as [[TheDanza Kate]] and Humphrey respectively.
* Creator/HannaBarbera's ''WesternAnimation/TheAmazingChanAndTheChanClan'' initially used Asian-American actors to voice the kids, but when they were hard to understand most of them (with the exceptions of Robert Ito and Brian Tochi) were replaced by white actors like Creator/JodieFoster (yes, ''that'' Jodie Foster).
* Akiko from ''WesternAnimation/AmericanDad'' was voiced by Creator/GreyDeLisle in her first couple of (minor) appearances, but Grace Park took over the role when the character got her first major role in "Best Little Horror House in Langley Falls".
* In ''WesternAnimation/{{Archer}}'', Creator/TomKane (from ''WesternAnimation/ThePowerpuffGirls1998'') took over as the voice of Woodhouse starting in the fifth season, replacing George Coe (a lesser-known member of the original cast ["The Not Ready for Primetime Players"] of ''Series/SaturdayNightLive'').
* ''WesternAnimation/{{Arthur}}'':
** Because they used child actors rather than adults that can do kids' voices, some of the characters had many different actors over the course of the series, most notably DW (always voiced by [[CrossdressingVoices young boys]]), Brain and Arthur himself. Also, Brain's voice got really deep before they replaced him and so did Arthur's.
** Catherine Frensky switched voice actors from Patricia Rodriguez to Alexina Cowan after season 7. Cowan herself was later replaced by Robyn Thaler Hickey.
** The French dub also went on a journey. Seasons 1-6 were dubbed in Montreal in-house by Cinar. Seasons 7-15 were dubbed in Paris at the Chinkel studio. Since Season 16, the dub moved to Belgium.
** Almost everybody is recast in ''WesternAnimation/ArthursMissingPal'' with the exceptions of [[Creator/BruceDinsmore Binky Barnes, David Read]] and [[Creator/DanielBrochu Buster Baxter]], as the voice cast for that film was Los Angeles based.
* On ''WesternAnimation/TheAtomAntShow'', the voice of the titular character, Howard Morris, was replaced in season two with Creator/DonMessick after Morris left due to a dispute with Hanna-Barbera. This also caused Messick to replace Morris as the voice of Mr. Peebles on ''WesternAnimation/MagillaGorilla'' (which had made a ChannelHop from syndication to ABC that year).
* ''WesternAnimation/AtomicBetty'':
** Due to the passing of Creator/LenCarlson in 2006, some of his characters were recast in the third season as a result:
*** Minimus is now played by Creator/DwayneHill starting with "No Space Like Home", as well as Spindly Tan Kanushu starting with "Spliced".
*** Greenbeard is now played by Creator/RonPardo in "Arr! It is 'olidays!".
*** Pharaoh is now played by Creator/TonyDaniels in "Night of the Living Mummies".
*** X-5's uncle B-1 is now played by Creator/JamieWatson in "Rodeo Robots".
** Betty's grandfather Jimmy was originally voiced by Creator/WilliamShatner in "The No-L Nine", but when the character returned in "Wedding Crashers", he was replaced by Creator/GaryKrawford.
** Noah's dad Mr. Parker was originally voiced by Creator/RobertSmith in his first appearance in "The Strange Case of Minimus-Hyde", but then was replaced by Creator/DwayneHill in all other appearances.
** Sarah was voiced by Creator/CatherineDisher for most of her appearances, while Creator/MelanieTonello voiced her in "Girl Power".
** Empress Narcissistad was voiced by Creator/MarthaMacIsaac in her first appearance in "Battle of the Bots", while Creator/RebeccaBrenner voiced her in "Star-Crossed Lovers".
* In ''WesternAnimation/AvatarTheLastAirbender'', Creator/{{Mako}}, the voice of Iroh, died when they were just about finished with the second season, and was replaced by Greg Baldwin (and given a touching sendoff in Iroh's DayInTheLimelight episode).
* In Season 1 of ''WesternAnimation/TheAvengersEarthsMightiestHeroes'', Constrictor was voiced by Creator/CamClarke. Come Season 2, Creator/TroyBaker is his voice actor.
* WesternAnimation/AugieDoggieAndDoggieDaddy have several voice actors:
** Augie Doggie was first voiced by Daws Butler, who voiced the character in all Hanna-Barbera media up until his death in 1988. His appearance in ''A Yabba-Dabba-Doo Celebration!: 50 Years of Hanna-Barbera'' had him voiced by Greg Berg. Patric Zimmerman then took over the role and voiced Augie in ''Fender Bender 500'' and ''Yo Yogi!''. Augie had another voice actor change in ''Harvey Birdman: Attorney at Law'', with  Chris Edgerly voicing the character. Finally, in ''WesternAnimation/{{Jellystone}}'', Georgie Kidder took over the character, [[GenderFlip now a female]].
** Doggie Daddy also had several voice actor changes. Doug Young voiced the character in the original shorts, but his retirement from voice acting resulted in John Stephenson taking over starting in ''Yogi's Ark Lark''. John would go on to voice the character in every single Hanna-Barbera media featuring the character up until ''Yo Yogi!''. His appearance in ''Harvey Birdman: Attorney at Law'' had the character voiced by Maurice [=LaMarche=]. Finally, in ''WesternAnimation/{{Jellystone}}'', the character was voiced by CH Greenblatt.
* This happens quite often with ''WesternAnimation/{{Barbie}}'':
** Barbie has been voiced by many different women: Sharon Lewis in ''WesternAnimation/BarbieAndTheRockersOutOfThisWorld'', then Creator/KellySheridan, Diana Kaarina, Creator/KateHiggins, Creator/EricaLindbeck, and currently America Young, as well as Creator/JodiBenson for her appearances in the ''Franchise/ToyStory'' series. Dubs seem to follow this trend too:
** The Albanian dub generally fluctuates between her being voiced by Luljeta Bitri and Creator.SuelaXhonuzi.
** The Dutch dub has had her voiced by Laura Vlasbom and Roos van der Werden.
* ''WesternAnimation/TheBatman'':
** Chief Rojas was voiced by Creator/EdwardJamesOlmos in his first appearance, then by Creator/JesseCorti in all of his other ones.
** Creator/RichardGreen replaced Frank Gorshin as Strange after the latter's death.
** Bane was voiced by Creator/JoaquimDeAlmeida for his debut in "Traction", then by Creator/RonPerlman for his cameo in "Team Penguin", then his grunts by Creator/ClancyBrown in "The Batman/Superman Story".
* ''WesternAnimation/BatmanTheBraveAndTheBold'':
** Done bizarrely in-universe (with the "voice actor" being represented by a glowing sphere of light in the character's throat) in the finale, when RealityWarper FourthWallObserver Bat-Mite, desiring a DarkerAndEdgier Batman show, forces the show to [[JumpingTheShark jump the shark]]. Among the changes he makes over the course of the episode is changing the voice actor of Aquaman (who he notes is the BreakoutCharacter) from Creator/JohnDiMaggio to Creator/TedMcGinley. Heroic FourthWallObserver ComicBook/AmbushBug even tricks Ted into breaking character.
** There were also two real life examples of this on the show. Poison Ivy was originally voiced by Creator/JenniferHale, but was replaced by Creator/VanessaMarshall in her major role in the teaser segment of "The Mask of Matches Malone". ComicBook/{{Katana}} was initially voiced by Vyvan Pam, but was replaced by Creator/KimMaiGuest for all her subsequent appearances.
*** Also done with Two-Face: he was voiced by Creator/JamesRemar in his first appearance, his ''[[WesternAnimation/BatmanTheAnimatedSeries TAS]]'' voice actor Creator/RichardMoll (Bull the bailiff on ''Series/NightCourt'') in his second, and by Remar again in his third.
** On January 9, 2018, there's a DVD movie called ''WesternAnimation/ScoobyDooAndBatmanTheBraveAndTheBold'', which, as you can guess from the title, is a crossover with Scooby-Doo. While all the returning characters have role reprises, some of them are the other Darrin to this series. For example:
*** In the April Fool's Day episode "Bat-Mite Presents: Batman's Strangest Cases!", which came out in 2011, Velma was voiced by her regular voice actress at the time, Creator/MindyCohn. This movie came out in 2018, and thus her current regular voice actress, Creator/KateMicucci, voices Velma here.
*** Despite returning as Martian Manhunter, Creator/NicholasGuest is replaced as the Question by his ''Franchise/DCAnimatedUniverse'' voice actor, Creator/JeffreyCombs.
*** Creator/TomKenny reprises the role of The Penguin from ''WesternAnimation/TheBatman'', replacing his ''The Brave And The Bold'' actor, Creator/StephenRoot.
*** Creator/TaraStrong reprises the roles of both Harley Quinn and Poison Ivy from various projects like ''WesternAnimation/DCSuperHeroGirls'', replacing Meghan Strange in the former role and both Creator/JenniferHale and Creator/VanessaMarshall in the latter role.
* Since ''WesternAnimation/TheBackyardigans'' are not only [[ChildrenVoicingChildren voiced by kids]], but have separate voices for [[NonSingingVoice singing]], it's only fitting they would have these.
** Pablo was voiced by Creator/ZachTylerEisen in Season One. Jake Goldberg took over for the rest of the series.
** Uniqua and Austin's singing voices were provided by Jamia Simone Nash and Thomas Sharkey for most of the series. In the final season, their singing voices came from Avion Baker and Nicholas Barasch.
** In Seasons One and Two, Tasha was voiced by Naelee Rae (speaking) and Kristin Klablunde (singing). In Seasons Three and Four, she was voiced by Gianna Bruzzeuse (speaking) and and Gabriella Maluk (singing).
** Last but [[VerbalTic certainly]] not least, there is Tyrone, who holds the record for the Backyardigan with the most voice changes. In Season One, it was Reginald Davis Jr. (speaking) and Corwin C. Tuggles (singing). In Season Two, it was Jordan Coleman (speaking) and Leon G. Thomas (singing). In Season Three, Jordan stuck around, while Damani Roberts took over for Leon Thomas for a bit before both boys were replaced by Tyrel Jackson Williams. In Season Four, Tyrel stuck around, while Chris Grant Jr. took over the speaking part.
** In the Brazilian Portuguese dub, the only cast member who ''wasn't'' replaced was Gabriela Milani as Uniqua.
** In the Latin Spanish dub, Tyrone and Austin's voice actors were replaced after they went through puberty.
* ''WesternAnimation/Ben10:''
** A comprehensive list would be ''impossible.'' Ben, Gwen, and Kevin changing between the original series and Alien Force are due to [[TimeShiftedActor the characters growing up]], but the overwhelming majority of main and recurring characters ''and Ben's alien forms'' change actors between the original series and Alien Force/Ultimate Alien, and then from Ultimate Alien to Omniverse, with no in-universe change. With most characters, the voice ''style'' remains the same (from AF/UA to Omni, Azmuth goes from sounding ''almost'' exactly like [[Series/StarTrekDeepSpaceNine Odo]] to exactly like Odo due to actually having his VA be Creator/ReneAuberjonois), sometimes not (you'll hardly believe Vilgax is the same character between the original and AF due to a switch between Creator/SteveBlum and Creator/JamesRemar. Also, day-one Azmuth had a high-pitched voice.) Somehow, Grandpa Max (Creator/PaulEiding), Hex (Creator/KharyPayton), Charmcaster (Creator/KariWahlgren), and Dr. Animo (Creator/DwightSchultz) have managed to sneak through with the same voice actor from day one to the present. Even then, Eiding would be replaced by Creator/EricBauza for the [[WesternAnimation/Ben102016 2016 reboot]]. While the alien forms' voices changing could be attributed to the changes the Omnitrix has gone through, as both it and the voices typically change with the start of a new series; the ''WesternAnimation/Ben10Omniverse'' episode "Universe Vs. Tennyson" suggests that the rest of the unexplained changes in voice (as well as appearance) between series are the result of [[RealityWarper Celestialsapiens]] casually altering the universe, leading to a case of TheNthDoctor instead.
** Grandpa Max's French voice actor, Creator/MarcAlfos, died during the first season of ''Omniverse''. He was replaced by Creator/PaulBorne.
* ''WesternAnimation/BikerMiceFromMars'':
** Napoleon Brie's minion Number One was voiced by Creator/MarkHamill for most of his appearances, but was voiced by Creator/JeffBennett during his final appearance in the episode "Hit the Road, Jack".
** Modo's nephew Rimfire was originally voiced by Creator/RobPaulsen in the three-part episode "Back to Mars" (with Leeza Miller-[=McGee=] voicing him when he's seen as a child in a flashback), but is voiced by Creator/BrianAustinGreen for the remainder of his appearances in the original series. His single appearance in the 2006 revival, "Break Up", has Brian-Austin Green replaced by Creator/JessHarnell.
** Other instances of characters being recast in the 2006 revival include:
*** Creator/LisaZane replaces Leeza Miller-[=McGee=] as the voice of the Biker Mice's ally Charley Davidson.
*** While Peter Strauss reprises his role as Stoker for five episodes, the rest of the series has him replaced by Creator/JimWard.
*** Leah Remini's role as Carbine is now played by Dina Sherman.
*** Creator/JenniferHale replaces Creator/KathSoucie as the voice of Vinnie's love interest Harley.
*** Aside from the aforementioned replacement of Brian Austin-Green as the voice of Rimfire, Creator/JessHarnell also replaces Creator/BradGarrett as Limburger's henchman Greasepit and Stu Rosen as the villain Pit Boss. He also replaces Creator/JeffBennett as the voice of the Plutarkian leader Lord Camembert even though Bennett appeared on the revival as the voice of Ronaldo Rump's British cousin Sir Richard Brand-Something.
*** Dr. Catorkian is usually voiced by Creator/JessHarnell, but Creator/JimWard fills in for him in the episode "Manchurian Charley".
*** Cataclym's main voice actor is Creator/ClancyBrown, but his grunts in "Biker Mice Down Under" and "Once Upon a Time on Earth, Part One: Stoker's Gambit" are provided by Dorian Harewood, while his voice actor in the LicensedGame for Platform/PlayStation2 was the late James Avery.
* The ''Bob & Doug Show'' features Dave Coulier replacing Creator/RickMoranis in the role of Bob [=McKenzie=]. Since these are animated characters and Dave sorta sounds or tries his best to sound like Moranis, it's not such a big deal -- [[TheyChangedItNowItSucks or is it]]? Ironically, Coulier also replaced Lorenzo Music as Peter Venkman in ''WesternAnimation/TheRealGhostbusters'' - which is more fitting, as he sounds more like Creator/BillMurray than Rick Moranis.
* In ''WesternAnimation/BobbysWorld'', Bobby's older brother, Derek, was voiced by Kevin Smets in the first five seasons; for the remainder of the series, he was voiced by Pamela Adlon because Smets had gone through puberty.
* The entire voice cast for the ''WesternAnimation/{{Bratz}}'' animated series was replaced for the second series (following a long hiatus). The voice actors used in the first series of episodes were Los Angeles-based, such as Dionne Quan, Lacey Chabert and celebrity Wendie Malick. Season 2 and beyond's cast consists of Vancouver-based voice actors such as Maryke Hendrikse, Britt [=McKillip=], Brittney Irvin, Ashleigh Ball, Kelly Sheridan and semi-celebrity Ellie Harvie taking over Wendie Malick's role.
* ''WesternAnimation/TheBradyKids'': Greg, Peter, and Marcia were all recast for the second season, with the roles taken over by [[{{Nepotism}} relatives of]] the show's producer (Lou Scheimer) and director (Hal Sutherland): Erika Scheimer as Marcia, Lane Scheimer as Greg, and Keith Sutherland as Peter. At the same time, the opening sequence was changed to remove the live-action versions of all the kids (presumably so as to not show the departed actors).
* The sixth season of ''WesternAnimation/BubbleGuppies'' had Creator/FredTatasciore replace Tino Insana as Mr. Grouper due to the latter's untimely passing in 2017.
* ''WesternAnimation/BuzzLightyearOfStarCommand''
** There are two different voice actors for XR, Creator/LarryMiller and Creator/NeilFlynn. The two men trade places seemingly at random from episode to episode with no acknowledgement of a change. The metallic effect applied to the voices makes them sound identical at first, until you get to know the character and realize he has a disappearing accent.
** Interestingly, another character has the same voice actor throughout the series but sounds different in every episode.
** Buzz himself counts for this. "The Adventure Begins" film that started the series saw Tim Allen reprise his role from the ''Franchise/ToyStory'' films. When the actual series began Buzz was now voiced by Creator/PatrickWarburton (Puddy on ''Series/{{Seinfeld}}'' and, most famously, Joe Swanson on ''WesternAnimation/FamilyGuy''), who also proceeded to dub over Allen for the edited, multi-part version of "The Adventure Begins". (Actually, Warburton voiced Buzz in "The Adventure Begins" to start with, because his version was used for the TV version. For the DTV version released beforehand, Allen [[TheOtherMarty dubbed over]] Warburton's lines.)
* In ''[[ComicStrip/TheKatzenjammerKids The Captain and the Kids]]'' the villain John Silver was voiced by Creator/MelBlanc for most of his appearances, however in "The Captain's Christmas" he is voiced by Billy Bletcher who also voiced The Captain.
* ''WesternAnimation/CaptainFlamingo'': Kirsten was originally voiced by Vanessa Thompson in her first two speaking appearances before Creator/StephanieBeard took over in all subsequent appearances.
* ''WesternAnimation/CaptainPlanetAndThePlaneteers'' changed the majority of the voice cast as the series went on because the originals were rather high profile and cost more to use.
** Creator/WhoopiGoldberg was the original voice of Gaia, the Spirit of the Earth, but was replaced in the fourth season by Creator/MargotKidder.
** David Rappaport was the original voice of MAL (Dr. Blight's computer) in the first four episodes featuring Dr. Blight and MAL. Because Rappaport died while the first season was still in production, MAL was voiced for the rest of the series by Creator/TimCurry (which most fans will attest is the better voice for MAL).
** Creator/JeffGoldblum originally voiced Verminous Skumm in the first season, but Creator/MauriceLaMarche replaced him for the rest of the series.
** Duke Nukem was voiced by Creator/DeanStockwell for the first two seasons, and by Maurice [=LaMarche=] for the remaining seasons.
** Creator/MartinSheen voiced Sly Sludge for the first three seasons, while Creator/{{Jim Cummings|1952}} voiced the character starting with season four.
** Zarm was originally voiced by Music/{{Sting}} in the first two seasons, but was voiced by Creator/DavidWarner in the third season, and finally by Creator/MalcolmMcDowell for his last two appearances.
** Creator/MegRyan was originally the voice of Dr. Blight. When the show got rid of its [[CelebrityVoiceActor celebrity voice actors]] for cost reasons, she was replaced by Creator/MaryKayBergman.
** Looten Plunder's original voice actor was Creator/JamesCoburn (no relation to Captain Planet's voice actor David Coburn) until he was replaced by Ed Gilbert in season four.
** The Mexican Spanish dub also had several voice actor changes over the course of production. While Audiomaster 3000 handled the first season and two episodes of season 2, Salgado Productions handled the rest of the dubbing. [[http://doblaje.wikia.com/wiki/El_Capit%C3%A1n_Planeta_y_los_planetarios As with South Park, an attempt has been made to sum up all the changes]]. Captain Planet went through at least three voice actors, as did most of the Planeteers (save for Gi).
* In the ''WesternAnimation/CatDog'' episode "Rich Shriek, Poor Shriek", Shriek [=DuBois=]' father was voiced by Creator/{{Jim Cummings|1952}}. For his cameo in "The Great Parent Mystery", however, Shriek's father was voiced by Creator/BillyWest instead.
* ''WesternAnimation/ChalkZone'' has had a few cases of this trope.
** Blocky was originally voiced by Robert Cait in the first short on ''WesternAnimation/OhYeahCartoons'' before the show became a series. In the first season, Candi Milo took over the character, only for the role to go back to Robert Cait for the remainder of the series.
** Bathtub Granny was played by E.G. Daily in the first ''Oh Yeah! Cartoons'' short and was replaced with Miriam Flynn, who played her for the entire series run.
** Spy Fly (a minor character introduced in the show's second season) went through two voices. Tress [=MacNeille=] played her in "Disappearing Act" (her first episode), then Candi Milo took over for "Chip of Fools" and "Lost in Chalk", and then Tress [=MacNeille=] returned to play her in "Beanie Boys to Men" and played her for the rest of the series.
** Before Lars (the polar bear who's a minor character) was a named character (in the first two seasons, he was simply credited as "polar bear"), he went through a few voice actors. First Jess Harnell, then Daran Norris, Jeff Bennett, Frank Welker, and then back to Jess Harnell when the character was given a name.
* ''WesternAnimation/ChallengeOfTheGobots'':
** A.J. Foster was initially voiced by Candy Brown in the cartoon's FiveEpisodePilot "Battle for Gobotron", with Brown replaced by Leslie Speights for the remainder of the series as well as the movie ''[=GoBots=]: Battle of the Rock Lords''.
** Because of the death of his original actor Bob Holt, Cop-Tur was voiced by Arthur Burghardt in the final episodes of the series and ''[=GoBots=]: Battle of the Rock Lords''.
** Sparky Marcus voiced Nick Burns for the series, but he was replaced by Ike Eisenmann in the ''Rock Lords'' movie.
* ''WesternAnimation/ChickenRunDawnOfTheNugget'': While the European French dub of ''WesternAnimation/ChickenRun'' ran with CelebrityVoiceActor, this isn't the case for the sequel. Gilduin Tissier replaced Creator/GerardDepardieu as Rocky, Antonella Colapietro replaced Creator/ValerieLemercier as Ginger and Catherine Davenier replaced Creator/JosianeBalasko as Bunty.
* ''WesternAnimation/ChipNDaleParkLife'' has Donald voiced by his current French dub actor Sylvain Caruso instead of Tony Anselmo or Daniel Ross, due to the show being produced by French studio Xilam.
* ''WesternAnimation/{{Chowder}}'': Creator/KevinMichaelRichardson voiced Schnitzel in the pilot episode before Creator/JohnDiMaggio replaced him for the series. [=DiMaggio=] also replaced Music/ToneLoc as the voice of Chestnut.
* ''WesternAnimation/{{Clarence}}'':
** Show creator Skyler Page originally voiced the title character from the pilot to the middle of season one. After he was fired for sexually harassing female staffers and suffering from bipolar mood swings, Spencer Rothbell (who actually did more with the show than Page did; all Page did was come up with the show idea and the voice of his character) replaced him, starting with the episode "Goldfish Follies" (though some episodes before it had Skyler Page as Clarence with some unrecorded lines done by Spencer Rothbell).
** In the pilot episode (which was also used on the episode "Pilot Expansion"), Jason Marsden was the voice of Sumo. In-series, Creator/TomKenny voices him.
* ''WesternAnimation/TheClevelandShow'':
** Played straight with Cleveland Jr. who was voiced by Mike Henry in ''WesternAnimation/FamilyGuy'' but was recast with Creator/KevinMichaelRichardson in the spinoff.
** Also played straight with daughter Roberta Tubbs in ''The Cleveland Show'', who was played by Nia Long in the first production season. When the show resumed production, Long was tied up with other commitments and was replaced with Reagan Gomez-Preston for the rest of the show.
** Tim the Bear was recast after Season 2 when Seth [=MacFarlane=] grew tired of voicing him. He was replaced by Creator/JessHarnell (that didn't stop Seth from [[Film/{{Ted}} from voicing another bear a year later...]]).
* ''WesternAnimation/CodeLyoko''
** There were two abrupt voice-actor switches early in the series. Jodi Forrest replaced Christine Flowers as Sissi after only four or five episodes, while Matt Gézcy replaced Odd's voice actor after only two or three. One of the more unusual things about this switch is that it is made obvious that the episodes were dubbed out of order -- Forrest and Gézcy's voices are present in the third episode, but are back to the old actors in the fourth.
** Averted with Jeremie, whose [[VocalEvolution frequent voice changes]] made people think he had been replaced multiple times - but nope, it's Sharon Mann the whole time.
** The Italian dub moved from Turin to Milan after episode 26. Only Ulrich and Yumi's voice actresses made the move.
* The TropeNamer is invoked as part of a gag in an episode of ''WesternAnimation/TheCritic'':
-->'''Gay Gen-X'er 1:''' Ok, who was cuter: [[Series/TheBeverlyHillbillies Uncle Jed or Jethro]]?\\
'''Gay Gen-X'er 2:''' Jethro was a bimbo.\\
'''Both:''' Uncle Jed!\\
'''Gay Gen-X'er 2:''' Ok, ok. On ''Series/{{Bewitched}}'': Darrin Number 1 or Darrin Number 2?\\
'''Creator/PaulLynde:''' [[ButHeSoundsHandsome I liked Uncle Arthur.]] ''(cackles)''
* ''WesternAnimation/CodenameKidsNextDoor'':
** Numbuh Two's mother was originally voiced by Creator/CreeSummer in "Operation: T.O.M.M.Y.", but is instead voiced by Creator/CandiMilo for her remaining appearances.
** Minor villains Mr. Mogul and Big Brother were originally voiced respectively by Creator/RobPaulsen and Creator/JohnDiMaggio, but their appearances in the episode "Operation: M.O.V.I.E." instead has them voiced by Creator/DeeBradleyBaker and Creator/DaranNorris.
* ''WesternAnimation/CourageTheCowardlyDog'': Eustace Bagge was originally played by Lionel Wilson in the first 33 episodes of the series, who was replaced by Arthur Anderson for the rest of the series' run when Lionel became ill with pneumonia. Anderson was then replaced by Creator/WallaceShawn for the 2014 special ''The Fog of Courage'', who in turn was replaced by Creator/JeffBergman for the ''Franchise/ScoobyDoo'' crossover ''WesternAnimation/StraightOuttaNowhereScoobyDooMeetsCourageTheCowardlyDog''.
* In ''WesternAnimation/CowAndChicken'', Chicken's friend Flem was primarily voiced by Howard Morris, but was instead voiced by Creator/MauriceLaMarche in the episode "Lost at Sea".
* ''WesternAnimation/{{Cyberchase}}'':
** Buzz was originally voiced by Creator/LenCarlson, then by Phil Williams after Carlson's passing in 2006.
** After Creator/GilbertGottfried's passing in April 2022, the role of Digit was taken over by Creator/RonPardo starting with season 14 a year later.
** Slider was originally voiced by Creator/TimHamaguchi until season 10, where he was instead voiced by Creator/AustinDiIulio (who also voiced Fluff), due to Hamaguchi leaving the series after season 9.
* William Franklyn voiced the titular ''WesternAnimation/DangerMouse'' in the pilot film "The Mystery Of The Lost Chord". Sir David Jason replaced him when it became a series. Alexander Armstrong assumed the voice of the White Wonder in the 2015 reboot.
* ''WesternAnimation/DangerRangers'': Creator/JonathanHarris voices SAVO in the show's pilot episode. Following his death in 2002, Creator/CharlieAdler took over the role.
* Happened quite a bit in ''WesternAnimation/DannyPhantom''
** Creator/GreyDeLisle initially voiced several characters before being replaced by other actors when these characters started to have larger roles:
*** Dora in her non-dragon form in "Parental Bonding" before Susan Blakeslee took over in "Beauty Marked".
*** Valerie Gray in her first two appearances ("Parental Bonding" and "My Brother's Keeper") before Creator/CreeSummer took over after becoming a recurring character in "Shades of Gray".
*** Star in her first few appearances before Creator/TaraStrong took over in "Beauty Marked".
** Creator/KevinMichaelRichardson replaced Mathew St. Patrick as the voice of Skulker after his third appearance.
*** He also started off as the voice for Dora's dragon form before Susan Blakeslee replaced him in "Beauty Marked".
** The Lunch Lady Ghost was voiced by Patricia Heaton in her first appearance in the first episode "Mystery Meat". In later appearances she was voiced by Creator/KathSoucie.
** Mikey, a student at Casper High, was voiced by Creator/ColleenOShaughnessey (same voice actress as Jazz) in "One of a Kind". When he became a recurring character, he was voiced by Creator/DeeBradleyBaker.
** Krista Swan replaced Annasophia Robb as Danielle's voice when she reappeared a second time.
* ''Franchise/DCAnimatedUniverse'':
** Batgirl/Barbara Gordon has no fewer than five voice actresses during the course of DCAU. In ''WesternAnimation/BatmanTheAnimatedSeries'', she is voiced by Melissa Gilbert. In the ''[[WesternAnimation/BatmanAndMisterFreezeSubZero SubZero]]'' direct-to-video movie, she's replaced by Mary Kay Bergman. In the revamp of the show, Creator/TaraStrong takes over the role in the ''The New Batman Adventures''. In ''WesternAnimation/BatmanBeyond'', Stockard Channing voiced an older Barbara Gordon. In ''WesternAnimation/BatmanBeyondReturnOfTheJoker'', the older Barbara is voiced by Angie Harmon, but Creator/TaraStrong voiced the younger Batgirl/Barbara Gordon in flashbacks.
** Music/PaulWilliams voices the Penguin throughout the run of ''Batman: TAS'' and ''The New Batman Adventures'', but is replaced by Creator/DavidOgdenStiers in the Direct-to-DVD movie tie-in, ''WesternAnimation/BatmanMysteryOfTheBatwoman''.
*** Likewise, Henry Silva was replaced by Hector Elizondo for Bane.
** After the {{Retool}}, a few character such as Scarecrow and Killer Croc were recast.
** [[ComicBook/{{Robin}} Tim Drake]] also underwent several different actors. He was initially voiced by Matthew Valencia in ''The New Batman Adventures'', but was then played by Eli Marienthal and Shane Sweet in ''WesternAnimation/StaticShock'', and Creator/ScottMenville in the ''[[VideoGame/BatmanRiseOfSinTzu Rise of Sin Tzu]]'' video game.
** ''WesternAnimation/JusticeLeague'':
*** Franchise/{{Superman}} was initially voiced by Creator/TimDaly in ''WesternAnimation/SupermanTheAnimatedSeries'', but was then played by Creator/ChristopherMcDonald in ''WesternAnimation/BatmanBeyond''. Daly was replaced by Creator/GeorgeNewbern in ''WesternAnimation/JusticeLeague'' and ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'', because Daly was tied up with the short-lived ''Series/TheFugitive'' remake.
*** On ''S: TAS'', Creator/CharlieSchlatter voiced the Flash in the episode Speed Demons, but when it came time for ''Justice League'', Creator/MichaelRosenbaum was cast to replace him in the role.
*** Due to budgetary issues, as there's a limit to how many actors they use per episode, when Metallo, Toyman, and Livewire showed up as part of the Superman Revenge Squad in the episode "Hereafter", Hawkgirl's voice actress Creator/MariaCanalsBarrera voiced Livewire instead of Lori Petty, while Creator/CoreyBurton pulled triple duty and served as a stand in for Creator/MalcolmMcDowell as Metallo, Bud Cort as Toyman and replacing Miguel Ferrer as the Weather Wizard. Both Cort and [=McDowell=] later reprised their roles in ''Justice League Unlimited.''
*** Creator/ChrisCox replaced George Eads as Captain Atom.
*** Creator/OdedFehr and Creator/JenniferHale replaced [[Series/StElsewhere George DelHoyo]] and Jennifer Lien respectively as Comicbook/DoctorFate and Inza.
*** Creator/RonPerlman replaced Steve Sandor, who voiced the character in ''S: TAS'', as Orion.
*** Creator/MichaelTWeiss replaced Creator/BillyZane as Jason Blood and Etrigan.
*** Creator/RobertFoxworth replaced Creator/VictorBrandt as Professor Hamilton.
*** As the role was already written to only consist of roars and screams, producer Creator/BruceTimm replaced Creator/MarkHamill as Solomon Grundy in the ''JLU'' episode, "Wake the Dead".
* ''WesternAnimation/DextersLaboratory''
** Shortly after the show came back from a long 3-year hiatus, Creator/ChristineCavanaugh left the series and retired from voice acting. Creator/CandiMilo, who was hired to replace her as the voice of Dexter, sounded absolutely nothing like the original (Milo also voiced Dexter on the series finale of ''WesternAnimation/TimeSquad'' in which Larry and Tuddrussell try to find a replacement orphan for Otto after losing him on a trip to 2001 to stop UsefulNotes/GeorgeWBush from making the world's biggest ball of twine).
** In addition, Dee Dee's voice switched from Allison Moore to Kat Cressida after the first 13 episodes when Allison wanted to focus on her live-action/stage work. When the show returned from the hiatus, Allison returned to play Dee Dee for another season since Creator/GenndyTartakovsky wanted to focus on changing a few voices around. Kat Cressida returned to the role again after a season at the request of Creator/CartoonNetwork who felt viewers were most used to her.
** Action Hank gets a speaking role in three episodes, but each of them give him a different voice actor. He is voiced by Michael Armstrong in "Beard to be Feared", John Garry in "Decode of Honor", and Creator/KevinMichaelRichardson in "911".
** The ''Dial M for Monkey'' segments had the chief of the organization Agent Honeydew worked for being voiced by Robert Ridgely in the first season. By season two, he was voiced by Earl Boen instead.
** While Creator/FrankWelker performed Monkey's sounds and vocal noises, his speaking voice in "The Lab of Tomorrow" was done by Creator/CoreyBurton.
** Justice Friends member Capital G was voiced by Creator/TomKenny in "Rasslor", but instead by Creator/GregEagles in "Last But Not Beast".
* Characters from the WesternAnimation/ClassicDisneyShorts also had voice acting changes, mostly due to the original voice actors dying. Mickey notably had four official voice actors: Creator/WaltDisney, Jim [=MacDonald=], Creator/WayneAllwine, and Bret Iwan. Donald has two (Clarence "Ducky" Nash and Creator/TonyAnselmo). Goofy had several voice actors (one of which is Pinto Colvig -- the voice of Grumpy and Sleepy on ''WesternAnimation/SnowWhiteAndTheSevenDwarfs'', the third little pig on the Creator/TexAvery UsefulNotes/WorldWarII cartoon "WesternAnimation/BlitzWolf", and the original actor who played Bozo the Clown), but is currently voiced by Bill Farmer.
* ''WesternAnimation/DinosaurTrain'':
** Buddy has had four voice actors (Phillip Corlett for seasons 1 and 2, Sean Thomas in season 3, Dayton Wall in season 4, and Chance Hurstfield in season 5).
** In Season 3 and onward, Laura Marr replaces Alexander Matthew Marr as Don.
* ''WesternAnimation/TheDisneyAfternoon'': Most of the shows had a pretty stable cast, but there were some exceptions:
** ''WesternAnimation/AdventuresOfTheGummiBears'' did have a few replacements during its six-season run: Originally [[TheStoic Gruffi]], [[ButtMonkey Toadwart]] and [[TheLancer Sir Tuxford]] were all voiced by ''WesternAnimation/RockyAndBullwinkle'' co-creator Bill Scott. He died after the first season, so Creator/CoreyBurton took over for him for both Gruffi and Toadwart (and doing a flawless imitation) while Roger C. Carmel was Tuxford. When Carmel died at the end of the second season, Brian Cummings was given the role.
** Likewise, Creator/PaulWinchell voiced Zummi for the first four seasons; after he suffered a non-fatal stroke in 1987, Jim Cummings took over for him for the final two. Likewise, Cummings replaced Winchell as Tigger in the ''Franchise/WinnieThePooh'' films and shows[[note]]Winchell had voiced Tigger in the first two seasons for ''WesternAnimation/TheNewAdventuresOfWinnieThePooh'', but Cummings took over for Winchell for the latter two when Winchell's health took a turn for the worse[[/note]]. While they interchanged between the two actors for a short time, the role was finally handed permanently to Cummings after ''The Tigger Movie'', for which Winchell was intended to record lines until his voice was considered too aged to properly voice the character anymore.
*** Cavin had a total of 5 different actors for the show's 6-year run; Christian Jacobs (now the lead singer for Music/TheAquabats) in season 1, Brett Johnson for season 2, David Faustino (yes, [[Series/MarriedWithChildren that]] [[WesternAnimation/TheLegendOfKorra one]]) for season 3, Creator/JasonMarsden for seasons 4&5 and R.J. Williams (see below) for the final season.
*** Another ''WesternAnimation/TheDisneyAfternoon'' example: In ''WesternAnimation/TaleSpin'', Kit Cloudkicker was voiced by two actors -- first Alan Roberts, then R.J. Williams. The two-part episode "A Bad Reflection on You" uses both Roberts and Williams; it's difficult to tell them apart, but you can do it if you're familiar with the subtle differences in their voices and you listen carefully.
*** Earlier episodes of ''WesternAnimation/ChipNDaleRescueRangers'' had Peter Cullen providing the voice for Monterey Jack, though later episodes had Jim Cummings filling the role (using the same voice he had used for Monterey Jack's father in an earlier episode). Series creator [[WordOfGod Tad Stones]] said that the switch was made because they weren't getting enough humor out of the script readings.
* ''WesternAnimation/DocMcStuffins'':
** [[https://www.facebook.com/pages/Laya-Hayes/1474296022791684 Laya DeLeon Hayes]] replaced Kiara Muhammad as Doc starting with Season 3.
** Andre Robinson replaced Jaden Betts as Donny starting with Season 3.
** In the mini-series ''The Doc Files'', Ben Schwartz voices Stuffy instead of Robbie Rist.
** Amy Seadris voiced Dress Up Daisy in Season 2, while Creator/GreyDeLisle] took over in Season 3.
** In the ''Winnie the Pooh'' crossover episode "Into The Hundred Acre Wood", Oliver Bell voices Christopher Robin, who was last voiced by Jack Boulter in the 2011 ''Winnie the Pooh'' film.
** Season 2's Christmas special had Santa voiced by Jeffrey Tambor. With the sexual allegations towards him at the end of 2017, Season 5's Christmas special the following year has him voiced by Justin T. Bowler.
** Darla was voiced by Molly Ringwald in her first two appearances. Later on, she was voiced by Creator/KariWahlgren.
** Melinda the Mermaid was voiced by Dharbi Jens in Seasons 1-2. In Season 3, she's voiced by GK Bowes.
* ''WesternAnimation/DoraTheExplorer''[='=]s original voice actress, Kathleen Herles, was replaced by Caitlin Sanchez in 2006 when she wanted to focus more on her school work. Sanchez herself was replaced with Fatima Ptacek after a nasty fallout with [[StageMom her parents]] and Viacom over her salary.
* Several voices in ''WesternAnimation/{{Doug}}'' switched when it went from Creator/{{Nickelodeon}} to Creator/{{Disney}}, including the title character's. Creator/BillyWest played Doug in the Nickelodeon version. The Disney version has Thomas [=McHugh=] as the new voice of Doug. Roger the bully went from [[ActingForTwo also being voiced by Billy West]] to being voiced by Chris Phillips. Billy West apparently left the show when Disney refused to match Nickelodeon's salary and has since criticized [=McHugh=]'s performance.
* The narrator for ''WesternAnimation/TheDreamstone'' was Peter Craze in Season 1, he was replaced by Gary Martin afterwards. The replacement is surprisingly similar considering the latter also voices [[EvilSoundsDeep Zordrak]]. Urpgor's voice actor also changes for the final season, from Leonard Whiting to Colin Marsh.
* ''Franchise/DuckTales'':
** Donald Duck's nephews were voiced by Russi Taylor in ''WesternAnimation/DuckTales1987'', and she would go on to voice them in most later appearances. However, in the ''WesternAnimation/MickeyMouseWorks'' shorts and ''WesternAnimation/HouseOfMouse'', the nephews are instead voiced by Creator/TonyAnselmo (the replacement voice of Donald Duck after Clarence Nash died).
** ''WesternAnimation/DuckTales2017'':
*** The entire cast of the 1987 series was replaced for the 2017 reboot with new actors, especially after the death of Creator/AlanYoung, who has now been replaced with Creator/DavidTennant. The only exceptions are Donald and Von Drake, who retain their traditional voice actors, Creator/TonyAnselmo and Creator/CoreyBurton respectively.
*** The beginning of "Beware the Buddy System!" establishes ''WesternAnimation/DarkwingDuck'' as an in-universe TV show, with Megavolt voiced by Keith Ferguson instead of Creator/DanCastellaneta (who does a nearly spot-on impression). Jim Cummings and Michael Bell still voice Darkwing Duck and Quackerjack. [[spoiler:In a twist, Darkwing's civilian identity, Drake Mallard, is later introduced in "The Duck Knight Returns!" as a real person voiced by Chris Diamantopoulos, playing the trope straight. And funny enough, Drake is replacing Darkwing's old actor [[TheDanza Jim Starling]] in a reboot production, making him an ''in-universe'' example of the trope as well.]]
*** The same happens in the Japanese dub, as the entire cast was replaced, with only Creator/KoichiYamadera and Creator/ToshikoFujita reprising their roles as WesternAnimation/DonaldDuck and Goldie respectively, albeit someone else will have to voice Goldie now, as the latter passed away in December 2018.
*** Inverted with the Latin American Spanish dub, as Arturo Mercado and Francisco Colmenero are the only voice actors who reprise their roles as Scrooge and Flintheart Glomgold, respectively.
*** Mostly averted in Spain, except Scrooge is now voiced by Jose Escobosa, as Carlos Revilla (who was also the original series's voice director) had died in 2000.
*** When the preteen Donald Duck made his debut he was voiced by the late Russi Taylor. Following her passing, she was replaced by Creator/CristinaValenzuela for "The First Adventure".
* ''WesternAnimation/DragonTales'' was hit hard with this in its Latin Spanish dub. While Audiomaster 3000 did Season 1, Season 2 was handled by Futura and Season 3 was handled by Dubbing House. As a result, the cast changed a lot. Zak went through 5 different voice actors (Creator/EnzoFortuny and Arturo Mercado to name two). Ord started out with Francisco Reséndez but then quickly switched to Creator/HermanLopez who voiced him for the rest of the series, save for some Season 2 episodes were Francisco Colmenero took over the role and some Season 3 episodes where Creator/MarioCastaneda voiced him. Like with ''South Park'' and ''Captain Planet'', [[https://doblaje.fandom.com/es/wiki/Dragon_Tales Doblaje Wiki has attempted to document all the changes]].
* ''WesternAnimation/EdEddNEddy'' had a couple cases of this:
** Nazz was originally voiced by Creator/TabithaStGermain for the character's first appearance, and was subsequently replaced by Creator/ErinFitzgerald (the same voice actress who plays May Kanker). When Fitzgerald left the show after the second season to move to the United States, Jenn Forgie was hired as the new voice of Nazz and May. Danny Antonucci, the creator of the show, was so much in love with Fitzgerald's take on the roles that he demanded she return for the show's fourth season onwards. Most of Jenn's dialogue was later re-recorded before her episodes were broadcast.
** After Toshitaka Shimizu's death, Eddy was voiced by Creator/WataruTakagi for the rest of the show's Japanese dub.
* ''WesternAnimation/FamilyGuy'':
** The role of Meg Griffin was played by an uncredited Creator/LaceyChabert during the first production season and was replaced by Creator/MilaKunis for the remainder of the series. [[note]]This was lampshaded many times over the course of the series. Once, when Peter warns Lois she could be replaced, he mentions Lacey Chabert's name as a threat, to which Lois immediately quiets down and mutters "Okay, I'll behave". Brian and Stewie also make note of Meg sounding different when they time traveled in a 2012 episode to an earlier episode with Chabert as the voice (where she actually received credit).[[/note]]
** Spoofed when Stewie notes that Creator/JimHenson had a "wait and see" attitude about his health, which led to his death and wrong-sounding Muppets[[note]]Although this skit erroneously claims Henson played Fozzie Bear; Fozzie was played by Frank Oz. However, they were correct that Henson portrayed Kermit and the Swedish Chef[[/note]].
** Played straight with Death; originally voiced by Creator/NormMacDonald for his first appearance, but then replaced by Creator/AdamCarolla for all other appearances, since [=MacDonald=] was unavailable.
** In her first appearance Lois' sister Carol was voiced by Carol Kane. In her second appearance a decade later, she is voiced by Julie Hagerty.
*** Same for Lois' brother, Patrick: originally voiced by Creator/RobertDowneyJr (who did it [[SoMyKidsCanWatch because his teenage son was a fan of the show]]) when the show was UnCanceled in 2005, the character returned for an episode seven years later ("Killer Queen") and was voiced by Danny Smith.
** Played straight in-universe when the Griffin family get their own reality show. After producers realize that Meg is the most unpopular character, they replaced her with a more attractive actress "playing" her. After the family was able to get Meg back at the risk of breaching their contracts, the rest of the family ended up being replaced as well (Tom Arnold as Peter, Creator/FranDrescher as Lois, Phillip Seymour Hoffman ["that fat guy from ''Film/BoogieNights''"] as Chris, Creator/MaryKateAndAshleyOlsen as Brian and Stewie, and the unnamed blond actress as Meg).
** In earlier seasons, the young children were played by the regular voice cast (mostly Creator/SethMacFarlane) imitating kid voices. In later seasons, they were voiced by actual children (though [=MacFarlane=] still voices Tom Tucker's son, Jake).
** The series has had three eras in Mexican Spanish: seasons 1-2 (Producciones Salgado), season 3 (made in Cuernavaca, Mexico instead of Mexico City), and currently New Art Dub (caused by a strike). As such, all the voice casts are different.
* ''WesternAnimation/FanboyAndChumChum'':
** In the original ''WesternAnimation/RandomCartoons'' pilot, Chum Chum was voiced by Creator/NancyCartwright and Lenny was voiced by Creator/JeffBennett. For the series proper, they were respectively recast with Creator/NikaFutterman and Wyatt Cenac.
** Francine is ordinarily voiced by Creator/CandiMilo, but her one line in "Pick a Nose" is done by Annie Mumolo instead.
* Both ''WesternAnimation/FantasticFourTheAnimatedSeries'' and ''WesternAnimation/IronManTheAnimatedSeries'' saw this:
** Comicbook/DoctorDoom had two voice actors in the first season of ''FF'': John Vernon and Neil Ross. In the second season, five characters got new voice actors: [[Series/BeverlyHills90210 Brian Austin Green]] as Johnny Storm/The Human Torch was replaced by Creator/QuintonFlynn in the second season, Doom got yet another voice actor with Simon Templeman, Jess Harnell replaced Ross as the Super-Skrull, Ron Feinberg replaced Creator/TonyJay as Terrax (though Jay did return as Galactus), and Edward Albert replaced Robin Sachs as the Silver Surfer. Creator/BradGarrett also replaced Creator/RobPaulsen from ''WesternAnimation/SpiderManTheAnimatedSeries'' as Hydro-Man and Rocky Carroll was replaced as Triton by Creator/MarkHamill.
** Dorian Harewood replaced James Avery in the role of Comicbook/WarMachine, Whirlwind, and Blacklash during Season 1 on ''Iron Man''. In the season 2, most of the cast was replaced, with Harewood, Robert Hays (Iron Man himself), Creator/{{Jim Cummings|1952}} (M.O.D.O.K.), and John Reilly (Hawkeye) being the only ones to return, though Chuck [=McCann=] was briefly replaced by Neil Ross was Blizzard in the Season 2 opening. Cummings was also replaced by Creator/TomKane as Century in the finale.
* Helper Hula from ''WesternAnimation/FinalSpace'' was voiced by Creator/GinaTorres in season 1 and Creator/VanessaMarshall in season 2.
* ''WesternAnimation/{{Firebuds}}'': Flash was originally voiced by Terrence Little Gardenhigh in Season 1. But starting with Season 2, Carter Jones took over.
* ''WesternAnimation/FiremanSam'':
** In Series 5, the show shifted to have the characters speak properly instead of being narrated over. As such, John Alderton, the original voice of all the characters, was replaced by John Sparkes as all the male characters (and Dilys Price), Joanna Ruiz as Sarah and James, and Sarah Hawland as Bella and Penny.
** In Series 6, a studio/artstyle shift also resulted in a total recast. John Sparkes was replaced by Steven Kynman (Sam, Elvis, and Norman) and David Carling (Station Officer Steele, Tom, and Mike), while Jo Ruiz and Sarah Hawland were replaced by Tegwen Tucker (Penny, Sarah) and Su Douglas (Helen, Mandy).
** In Series 6-7, James and Norman sounded nearly identical due to both being voiced by Steve Kynman. In Series 8, Kynman passed the role of James over to John Hasler.
* ''WesternAnimation/TheFlintstones'':
** The TV series recast everyone except for Wilma (played by Jean Vander Pyl) after the original 5-minute pilot.
** For the main TV series, Betty (originally voiced by Bea Benaderet) was replaced with Gerry Johnson for the final two seasons of the main show, as well as the movie. Johnson left shortly after the series, and Betty has been voiced by a number of actresses since. Alan Reed, Fred Flintstone's original voice, did Fred's voice on the debut episode of ''[[Franchise/ScoobyDoo Scooby's All-Star Laff-A-Lympics]]'', but died soon after and was replaced by Henry Corden, who would be his regular voice from then on. The voice of Barney Rubble was originally provided by Creator/MelBlanc, then briefly by Creator/DawsButler while Mel was in a coma following a near-fatal car accident. When Mel was well enough to do voicework again, he Other Darrinned ''himself'' by using a different voice style to better match Butler's (one episode even had Daws Butler's Barney voice replaced by Mel Blanc's in the middle of the episode).
** Following Blanc's death in 1989, Creator/FrankWelker began voicing Barney. Other actors that have played Barney over the years include Creator/KevinMichaelRichardson, Creator/JeffBergman, Hamilton Camp, and Scott Innes.
** These days, Creator/JeffBergman and Creator/JamesArnoldTaylor alternate the role of Fred Flintstone. Creator/TressMacNeille usually plays Wilma Flinstone, while Creator/GreyDeLisle plays Betty Rubble.
* In the French dub of ''WesternAnimation/ForkyAsksAQuestion'', Gauthier Battoue replaced Creator/PierreNiney as Forky. Niney had voiced him in ''WesternAnimation/ToyStory4''.
* ''WesternAnimation/{{Franklin}}'':
** They managed to keep the same voice, Creator/NoahReid, for Franklin for five seasons and two films, but then the original voice actor's voice got so deep that it just wasn't working anymore. So they got Creator/ColeCaplan, who had previously voiced a OneShotCharacter named Squirrel, to do the voice. Then, for the final film, they got Creator/CameronAnsell, one of the many voices of WesternAnimation/{{Arthur}}. They also ended up replacing the voices of several other characters in later seasons.
** Almost all of the original character voices have been replaced by others in ''Franklin and Friends'', but this isn't surprising, given it's been nearly fifteen years since the original series debuted. That said, the casting director has done a pretty good job of picking soundalikes for the originals on the whole. All of the kids have new voice actors, but a few of the adults retain their originals. These include, notably, both Mr. and Mrs. Turtle.
** The Finnish dub has this trope happening with Mr. Turtle, Mr. Owl and Bear who had their Finnish voice actors changed after only nine first episodes. Rabbit's voice actor changed in Season 3. Skunk was voiced by a female voice actor in a couple of episodes, while otherwise having a male voice actor doing the role.
** The Italian dub started in Turin, covering seasons 1-2. Starting in Season 3, the dub moved to Milan. Given how Milan and Turin's voice acting pools tend to bleed into each other thanks to the distance between the two cities (only a 1-2 hour drive for many), the voice actors for Franklin, his parents, and Beaver were kept while the rest of the characters were re-cast.
** In Brazil, seasons 1-5 were dubbed in São Paulo. Season 6 moved to Rio de Janeiro with a whole new cast.
** The Latin Spanish dub started in Mexico, covering seasons 1-5 and the first two movies. For Season 6, the dub moved to Venezuela, with the entire cast replaced.
[[/folder]]

[[folder:G-N]]
* In the Creator/DiCEntertainment-produced continuation of ''WesternAnimation/GIJoeARealAmericanHero'', a lot of characters ended up having their voice actors replaced.
** Ted Harrison replaces Creator/MichaelBell as Duke.
** Creator/MauriceLaMarche replaces Arthur Burghardt as Destro, Creator/CharlieAdler as Low-Light, Dick Gautier as Serpentor, Gregg Berger as Spirit, Creator/FrankWelker as Copperhead, and Jack Angel as Wet Suit.
** Ed Gilbert reprises his role as General Hawk before being replaced by Creator/DavidKaye in the second season.
** Suzanne Errett-Balcolm replaces Morgan Lofting as the Baroness after the first season.
** Lady Jaye's voice actress Mary [=McDonald=]-Lewis was replaced by Lisa Corps in the "Operation: Dragonfire" arc, who was in turn replaced by Suzanne Errett-Balcom for the remainder of the character's appearances.
* The death of Creator/DawsButler led to several of his Creator/HannaBarbera characters being taken over by other voice actors, notably Creator/GregBurson (WesternAnimation/YogiBear, WesternAnimation/HuckleberryHound, WesternAnimation/QuickDrawMcGraw, and {{WesternAnimation/Snagglepuss}}, among others) and Patric Zimmerman ([[WesternAnimation/TheJetsons Elroy Jetson]], Augie Doggie, and Dixie the Mouse).
* ''WesternAnimation/GravityFalls'':
** Strangely enough, in a commercial for Gravity Falls mealbags at Subway, Kristen Schaal does not voice Mabel. Even stranger, all of the dialogue for the twins in that CM is taken from clips of previous episodes, and they didn't dub over Jason Ritter's voice for Dipper.
** Chris Parnell voiced Preston Northwest for his brief appearance in season 1, while Creator/NathanFillion voiced the character when his role was expanded in season 2.
** Following the public reveal of Creator/LouisCK’s sexual harassment history in December 2017, it was found that Alex Hirsch went back and redid the lines for The Horrifying Sweaty One-Armed Monstrosity. This version is currently available on Creator/DisneyPlus and Hulu.
** Hirsch also replaced Scott Menville as Nate in season 2.
** In the Russian dub of season 2, Tatiana Vesyolkina was the voice of Wendy in most of the episodes, until the Weirdmageddon episodes, where Olga Shorokhova, Wendy's original voice actress, returned.
* As with ''WesternAnimation/MightyMouse'', Fellow Terrytoons stars ''WesternAnimation/HeckleAndJeckle'' had Dayton Allen as their voices in an early short. Syd Raymond took over or a few films, then Allen returned to the role until 1951, when Roy Halee took over. Allen returned to voice the two in the last H&J theatrical short, "Messed Up Movie Makers". Frank Welker took over in the Filmation show.
* ''WesternAnimation/HerculesTheAnimatedSeries'':
** Most of the movie's cast ''did'' return for the series, except for Creator/CharltonHeston, Creator/RipTorn, and Creator/DannyDeVito.
** An unusual, marginal example: Creator/TateDonovan returns as Hercules, but he portrays the younger version of the character, who was voiced by Creator/JoshKeaton in the movie.
** Amanda Plummer (the voice of Clotho, one of the Fates) was replaced by Creator/TressMacNeille.
** Pep Antón Muñoz was the voice of Hades in the European Spanish dub for a few episodes of the TV Series but was replaced for the rest of the series by Jordi Ribes. However, Muñoz returned to voice him in ''WesternAnimation/HouseOfMouse''.
** In the Latin American Spanish dub, Creator/JoseGilbertoVilchis replaced Music/RickyMartin as Hercules and Creator/HumbertoSolorzano replaced Ruben Trujillo as Hades. Oddly enough, [[CelebrityVoiceActor Tatiana]] reprised her role as Megara.
* The animated adaptations of ''ComicStrip/{{Garfield}}'' have gone through this:
** The very first animated version of Garfield, done for the 1980 CBS special ''The Sunday Funnies'', had Garfield voiced by Scott Beach, and Jon voiced by Thom Huge. For the first [[WesternAnimation/GarfieldSpecials animated special]] ''Here Comes Garfield'' two years later, Garfield was voiced by Lorenzo Music, and Jon by Sandy Kenyon. Huge returned as Jon for ''Garfield on the Town'' and all subsequent specials through ''Garfield Gets a Life'' in 1991, while also voicing him on ''WesternAnimation/GarfieldAndFriends'' (1988-94). Music voiced Garfield in nearly all appearances until his 2001 death, except for an early 1990s Alpo commercial that inexplicably used [[Series/TheSmothersBrothersComedyHour Tom Smothers]] instead.
** For the 2004 live-action movie, Garfield was voiced by Creator/BillMurray, while the upcoming [[WesternAnimation/TheGarfieldMovie 2024 animated film]] has him instead voiced by Creator/ChrisPratt.
** For the three direct-to-DVD movies released between 2007 and 2009 (''Garfield Gets Real'', ''Garfield's Fun Fest'', and ''Garfield's Pet Force''), Garfield and Jon are respectively voiced by Creator/FrankWelker and Creator/WallyWingert. These two also held those roles on ''WesternAnimation/TheGarfieldShow'' (2009-16) and have become the characters' main voice actors ever since.
** Nermal was voiced by Desirée Goyette on ''Garfield and Friends'', David Eisenberg in TheMovie, and Jason Marsden on the CGI movies and ''The Garfield Show''.
** On ''Garfield and Friends'', the Buddy Bears were voiced by Howard Morris (Billy), Thom Huge (Bobby), and Creator/GreggBerger (Bertie)... except for their debut in "Binky Gets Cancelled Again", where Lorenzo Music voiced Billy.
* Every character got recast for ''Toys/HeroFactory'''s ''Invasion from Below'' episode. [[ActingForTwo Since they got to be voiced by only a handful of people]], the male heroes sounded barely distinguishable -- save for Surge who out of nowhere adopted a thick Australian accent.
* ''WesternAnimation/HeyArnold'' went through many cast changes due to using real child actors, who have an annoying tendency to go through puberty.
** Arnold was voiced by ''five'' different actors: J.D. Daniels (the pilot episode), [[Creator/LaneToran Toran Caudell]] (Season 1 and Arnold's singing voice in "What's Opera, Arnold?"), Phillip Van Dyke (seasons 2 and 3), Spencer Klein (seasons 4 and 5 up to TheMovie), and Creator/AlexDLinz (the post-movie episodes "April Fool's Day" and "The Journal").
** Eugene also had four different voice actors: Christopher J. Castile (most of Season 1), Jarrett Lennon (the last few episodes of Season 1), Creator/BenDiskin (seasons 2-4), and Blake Ewing (Season 5).
** Sid was voiced by Sam Gifaldi for the vast majority of the show's run, but he was voiced by Sam's younger brother Taylor in "April Fool's Day" as Sam's voice had changed during the long hiatus between TheMovie and that episode.
** Curly had been voiced at different times by Adam Wylie, Creator/HaleyJoelOsment, Steven Hartman and Michael Welch. Curly's case is rather peculiar: Adam Wylie was his main voice actor, yet he was replaced for a couple episodes only to be shortly reinstated. ''Twice''.
** At various times, Iggy had been voiced by Joseph Ashton, Justin Shenkarow, and Marcus Toji. He is also one of the few child characters on the show to be voiced by an adult woman, as he was voiced by Creator/TressMacNeille in one episode.
** In fact, only four of the child voice actors kept their roles from the pilot episode (in 1994) until the final episode (in 2001): Jamil Walker Smith (Gerald), Creator/FrancescaMarieSmith (Helga; no relation between the two), Justin Shenkarow (Harold), and Christopher Walberg (Stinky). Jamil's voice did change during production, but the episode "Gerald's Tonsils" hand-waved the vocal change as Gerald having his tonsils removed and his voice sounding different because of a botched surgery. Justin's voice changed as well, only the change took place between the pilot and Season 1, so his voice for the actual series never really changed too much, aside from developing a raspier sound post-season 1 and since his character was 13, it didn't matter as much. Christopher's voice changed between seasons 4 and 5, but he stayed on with no explanation for the change. As for Francesca Marie Smith, her voice did become noticeably deeper throughout the series, but she never stopped sounding like Helga (as girls' voices do change during puberty, but it's not as dramatic as what happens when boys' voices change) and continues to voice her to this day.
** Thanks to the long gap between the show's original production run and ''[[WesternAnimation/HeyArnoldTheJungleMovie The Jungle Movie]]'', many voices were changed in 2016 since those voices either grew too old to reprise their roles, died or retired from voice acting. Most of the actors playing the boys have been replaced [[note]]Justin Shenkarow (Harold), Craig Bartlett (Brainy) and Danny Cooksey (Stoop Kid) are the lone exceptions[[/note]]. New cast members include:
*** Mason Vale Cotton as Arnold
*** Benjamin “L’il P-Nut” Flores as Gerald
*** Gavin Lewis as Eugene
*** Jet Jurgensmeyer as Stinky
*** Aiden Lewandowski as Sid
*** Nicolas Cantu as Curly
*** Laya Hayes replaces Lauren Robinson as Nadine
*** Creator/WallyWingert replaces the late Steve Viksten, who died in 2014, as Oskar, and also voices Mr. Hyunh, replacing Baoan Coleman.[[note]]He was originally going to also voice Dino Spumoni, but Dom Irrera, the voice of Ernie, contacted Rick Corso, who agreed to return to the role.[[/note]]
*** Creator/StephenStanton replaces Creator/VincentSchiavelli, who died in 2005, as Pigeon Man.
* The last two ''WesternAnimation/HollyHobbieAndFriends'' specials completely change the voices. This, combined with some other changes, apparently [[FranchiseKiller killed the series]].
* In ''WesternAnimation/HomeAdventuresWithTipAndOh'', Matt Jones is the only actor reprising their role from [[WesternAnimation/Home2015 the movie]].
* ''WesternAnimation/HoodwinkedTooHoodVersusEvil'' was a case of two Other Darrins, with Creator/AnneHathaway (the voice of Red) and Creator/JimBelushi (the Woodsman) replaced by Creator/HaydenPanettiere and Creator/MartinShort.
* Many characters from [[Franchise/DisneyAnimatedCanon classic Disney movies]] have new voices for their latest appearances such as the show ''WesternAnimation/HouseOfMouse'' and the ''Franchise/KingdomHearts'' video games (for obvious reasons, since most of the original actors are either retired or have been dead for decades).
** Belle was usually voiced by Paige O'Hara. However, during her ''WesternAnimation/HouseOfMouse'' incarnation, she was actually voiced by Jodi Benson (the voice of Ariel from ''WesternAnimation/{{The Little Mermaid|1989}}'', and who, coincidentally, was one of the first voice actresses considered for the role of Belle during the development of ''WesternAnimation/BeautyAndTheBeast''). As of ''WesternAnimation/SofiaTheFirst'', after O'Hara was deemed to have aged out of the role, Julie Nathanson has been voicing Belle (with the sole exception of ''WesternAnimation/RalphBreaksTheInternet'' where O'Hara returned to the role). On a related note, all of the bimbo triplets were voiced by Creator/KathSoucie (who originally only voiced the green one) after Creator/MaryKayBergman (the voice actress who voiced the red and yellow ones) died.
** Roxanne (Max's girlfriend from ''WesternAnimation/AGoofyMovie'') was voiced on ''WesternAnimation/HouseOfMouse'' by Creator/GreyDeLisle instead of her original VA Creator/KellieMartin. (Interestingly, in ''Mickey's Twice Upon a Christmas'', Max's SuspiciouslySimilarSubstitute girlfriend Mona is voiced by the very voice actress that [=DeLisle=] replaced (Kellie Martin).
** A notable exception to the rule is Hades from ''WesternAnimation/{{Hercules}}''. Creator/JamesWoods has said Hades is his favorite character to portray and that he loves the role so much he'll play it at any salary whenever Disney needs it until the day he dies.
** Another notable exception is [[WesternAnimation/TheLittleMermaid1989 Ariel]], voiced by the aforementioned Creator/JodiBenson, who has voiced every single animated incarnation of the character for Disney since ''1989'' and has discussed many times the intense responsibility she feels toward her -- partly because she truly does love her that much, and partly in memory of the late ''Mermaid'' lyricist Howard Ashman, whom she loved dearly.
* ''WesternAnimation/IAmWeasel'':
** Weasel's assistant Loulabelle was voiced by Susan Blakeslee in the second season and by Teresa Ganzel for her last appearance in the season 3 episode "Time Weasel".
** The first season had Admiral Bullets voiced by Creator/JessHarnell, but the character was voiced by Michael Gough during his appearances in the second and third seasons.
* All of the returning characters in ''WesternAnimation/TheIceAgeAdventuresOfBuckWild'', except for Buck, have been recast:
** Dominique Jennings replaces Music/QueenLatifah as Ellie
** Sean Kenin Elias-Reyes replaces Creator/RayRomano as Manny.
** Jake Green replaces Creator/JohnLeguizamo as Sid.
** Skyler Stone replaces Creator/DenisLeary as Diego.
** '''Non-acting example:''' Batu Sener takes over as the film's composer, replacing Music/JohnDebney from the fifth film, who in turn had replaced Music/JohnPowell from the second, third and fourth films. As a former protégé of Powell, Sener's score for ''Adventures Of Buck Wild'' incorporates many of the leitmotifs from Powell's work on the franchise.
* ''WesternAnimation/TheIncredibleHulk1996'':
** Creator/NealMcDonough as Bruce Banner and Creator/LouFerrigno as the green Hulk are this, as both halves of Banner were voiced by Creator/RonPerlman in his guest appearances on ''WesternAnimation/FantasticFourTheAnimatedSeries'' and ''WesternAnimation/IronManTheAnimatedSeries''. Regarding the guest appearance on the former, Luke Perry also replaced Benny Grant as Rick Jones.
** Creator/MauriceLaMarche plays Comicbook/DoctorStrange in this series while John Vernon plays him on ''WesternAnimation/SpiderManTheAnimatedSeries'' (though this is likely because Vernon was the voice of "Thunderbolt" Ross in this series).
** Likewise, Creator/LisaZane plays ComicBook/SheHulk in season 1 while Creator/CreeSummer plays her in Season 2.
** Creator/LouFerrigno briefly plays as the transforming Grey Hulk in season 1's finale, while Michael Donovan takes over when Grey Hulk makes his later appearances.
** And finally, Genie Francis plays Betty Ross for most of Season 1 while Creator/PhileceSampler plays her later in Season 1 and in Season 2.
* ''WesternAnimation/InspectorGadget'':
** The title character was voiced by Jesse White in the pilot episode ([[TheOtherMarty taking over from Gary Owens from an earlier version]]), but was replaced with Don Adams afterwords to get the full effect of having Gadget sound like [[Series/GetSmart Maxwell Smart]]. Creator/MauriceLaMarche took over the role in later media following Adams' death.
** Creator/MonaMarshall voiced Penny in the pilot, though Creator/CreeSummer would voice the character for the rest of the first season. After production moved from Toronto to Los Angeles, the role was given to Holly Berger for the remainder of the series. Erica Horn later took over the role for the Christmas special, and Tegan Moss has voiced the character in recent incarnations.
** Chief Quimby was voiced by John Stephenson in the pilot, by Dan Hennessy in the first season, and then by Maurice [=LaMarche=] in the second season.
** While Frank Welker voiced Dr. Claw in most episodes, Don Francks (father of Cree Summer) filled in for a few episodes where Welker was unavailable.[[note]]Don Francks was initially hired as Welker's full-time replacement for about 25 episodes due to recording moving to Toronto after the pilot. Since Don Adams was recording his Gadget lines in Los Angeles, Frank Welker was brought in to re-record most of Francks' episodes, but there were apparently a few they didn't get to for unknown reasons.[[/note]] Creator/BrianDrummond voiced the character in later media.
* ''WesternAnimation/JackieChanAdventures'':
** When Hak Foo originally debuted in the first season episode "The Dog & Piggy Show", he was voiced by Creator/{{Jim Cummings|1952}}. After he became a regular, starting with season 2, Creator/JohnDiMaggio took over the role. In "Deja Vu", when Jackie relives the events of Hak's debut episode [[FlashbackWithTheOtherDarrin DiMaggio still voices the character]].
** Likewise, Creator/JulianSands voiced Valmont, but only for seasons 1 and 2. Creator/AndrewAbleson voiced his handful of appearances in seasons 3 and 4.
** The Monkey King was voiced by Bill Tanzer in his first appearance and Creator/BillyWest in his second.
** After originally being voiced by Creator/CoreyBurton, all other appearances by Xiao Fung have him voiced by Glenn Shadix, who also voiced Tso Lan (Burton was actually never credited as Xiao Fung in any of the episodes where that character appears).
** Jade's future adult self in "J2: Rise of the Dragons" is voiced by Creator/LucyLiu. Her next appearance in "J2: Revisited" has her voiced by Jade's regular actress Stacie Chan.
* For ''WesternAnimation/JetsonsTheMovie'', there were several examples:
** Creator/DawsButler (Elroy), who died before production began, was replaced by Patric Zimmerman.
** Judy Jetson was a double-subversion, as she actually kept her original voice actress, Creator/JanetWaldo… but Janet was controversially [[TheOtherMarty overdubbed]] by pop singer Tiffany in post-production.
** And finally, both Creator/MelBlanc (Mr. Spacely) and George O'Hanlon ([[TheDanza George Jetson]]) died during production with some lines unfinished (O'Hanlon apparently died of a stroke ''in the recording booth''), so Creator/JeffBergman did the rest of their lines.
* ''WesternAnimation/JohnnyTest'':
** Dukey's voice actor changed from Louis Chirillo to Trevor Duvall in the fifth season when Louis moved to Brazil, resulting in much controversy. Fans still apparently have a hard time accepting that Dukey's voice has changed.
** Trevor also took over Louis' role of Mr. Henry Teachman, and Creator/BillMondy replaced Louis as Brain Freezer.
** Mary Test started out being voiced by Brittney Wilson, but Creator/AshleighBall took over the role in Season 2. Brittney Wilson returned to the role for Season 5 after Ashleigh Ball finished the role for Season 4. Ashleigh Ball would return to the role after Season 5. Both Brittney Wilson and Ashleigh Ball would then be replaced by Creator/EmilyTennant in the 2021 revival.
*** The two actresses also share the roles of Sissy and Missy Blakely in similar fashion, and Maryke Hendrikse filled in for Brittney once as Mrs. X and Mrs. Z.
* The ''WesternAnimation/JonnyQuest'' franchise:
** Tim Matheson voiced Jonny in the original '60s run. When Creator/HannaBarbera attempted to revive the series in 1986, Matheson was too old to reprise the role and was thus replaced by Creator/ScottMenville. Will Estes would replace him for ''WesternAnimation/JonnysGoldenQuest'', and would then be replaced by Kevin Smets for ''WesternAnimation/JonnyQuestVersusTheCyberInsects''. In the first season of ''[[WesternAnimation/JonnyQuestTheRealAdventures The Real Adventures]]'', he was voiced by J.D. Roth. After Hanna-Barbera decided to retool another Jonny Quest remake (The New Jonny Quest) into the show's second season, Roth was replaced by Creator/QuintonFlynn.
** Hadji was voiced by Danny Bravo in the original series, but the role was given to Creator/RobPaulsen for the '80s revival and telefilms. Michael Benyaer voiced Hadji in the first season of ''Real Adventures'', but was replaced with Paulsen for the later episodes.
** Creator/JohnStephenson voiced Benton Quest for the first five episodes of the '60s series, and was replaced by Creator/DonMessick for the remainder of it. Messick would continue to voice Dr. Quest for the '80s series and the films, until ''The Real Adventures'' cast George Segal in the role. After the second season began production, Messick attempted to reprise his role but wound up suffering a stroke. As a result, Creator/JohnDeLancie was chosen as the voice for Dr. Quest.
*** Messick was also the original voice for Bandit, but Creator/FrankWelker took over the part for ''Real Adventures''.
** Mike Road originally voiced Race Bannon in the '60s run of Jonny Quest, but was replaced by Granville van Dusen for the '80s revival. He was then replaced by Robert Patrick for the first season of ''The Real Adventures''. van Dusen would later reprise Race in the first two episodes of the second season, but the role would then shift again to Robert Foxworth for all the remaining episodes.
** Jessie Bannon was first voiced by [=Anndi McAfee=] in the telefilms, but her older teenage self would be voiced by Jesse Douglas in the first season of 'Real Adventures', followed by Jennifer Hale after the overhaul in production.
* ''WesternAnimation/TheJungleBook1967'':
** In the spinoff ''WesternAnimation/JungleCubs'', three of the main cast members voices were changed in the third season. In the first two seasons, Bagheera was voiced by Elizabeth Daily; in the third seasons, he was voiced by Dee Bradley Baker, in the first two seasons Hathi was voiced by Creator/RobPaulsen and in the third season by Stephen Furst, and Louie was voiced by Creator/JasonMarsden in Seasons 1 and 2 and by Creator/CreeSummer in Season 3. For Bagheera, it was explained that he was going through puberty. There was no explanation for Hathi's and Louie's changes, as Feurst only made him sound goofy, and the change for Louie was especially strange considering Marsden was still voicing Shere Khan.
** Notably, the special "Born to Be Wild" (featuring the characters in their adult forms) uses the cast's ''WesternAnimation/TaleSpin'' voice actors (with Creator/{{Jim Cummings|1952}} [[ActingForTwo providing most of the remainder of the cast]]). Tony Jay also voices Shere Khan in ''WesternAnimation/TheJungleBook2''.
* For ''WesternAnimation/KidCosmic'', the title character was voiced by an unknown child actor for the pilot. By the time the show entered full production, he aged out of the role and [[https://mobile.twitter.com/CrackMcCraigen/status/1371110773833883653 Jack Fisher]] was cast in the role.
* ''WesternAnimation/KimPossible'' villain Senor Senior Senior was voiced originally by Ricardo Montalban, who was occasionally unavailable due to health problems. During those times the role was voiced by Earl Boen.
* Two examples in ''WesternAnimation/KingOfTheHill'':
** For his first couple of appearances in the first season, John Redcorn was voiced by Victor Aaron when he died in a car accident. Jonathan Joss replaced him for the rest of the series.
** His biological son, Joseph Gribble, was voiced by Creator/BrittanyMurphy from Season 1 to early Season 5, and from mid-Season 5; for the rest of the series he was voiced by Breckin Meyer, this was done because Brittany Murphy was busy making movies, so the writers put Luann in college and had Joseph go through puberty, resulting in a change in voice and appearance.
** Because of the voice acting strike in 2005, most of the Latin Spanish cast was replaced (except Hank, Dale and Minh).
* ''Franchise/KungFuPanda'':
** ''WesternAnimation/{{Kung Fu Panda|1}}'': Usually when a voice actor dies, he needs a replacement. The Brazilian dubbing for the first film however managed a near-miracle: the guy who usually voiced Creator/DustinHoffman, Newton da Matta, died two years prior to that movie, in 2006. But Leonardo Camillo, who voiced Hoffman's Shifu, sounds exactly like him ([[https://www.youtube.com/watch?v=CMS4j2w0Xnc Newton]] - [[https://www.youtube.com/watch?v=eJ_GPRFO-d8 not-Newton]]).
** ''WesternAnimation/KungFuPandaLegendsOfAwesomeness'':
*** Similar [[WesternAnimation/ThePenguinsOfMadagascar to]] [[WesternAnimation/MonstersVsAliens2013 other]] Creator/DreamWorksAnimation shows that aired on Creator/{{Nickelodeon}}, most of the voice cast has been replaced except for Creator/JamesHong (Mr. Ping) and Creator/LucyLiu (Viper).
*** The Italian dub replaces only Po, Shifu and Mr. Ping. Also, after Crane's voice actor Danilo De Girolamo died, he was replaced with Creator/FrancoMannella... who was replaced with Creator/OresteBaldini in the third movie for unknown reasons.
* John Stephenson was the voice of Dread Baron on 1977's ''WesternAnimation/LaffALympics''. He was meant to be an expy of ''WesternAnimation/WackyRaces'' antagonist Dick Dastardly, although a comic book story tells that the Baron and Dastardly are brothers. The 1988 telefilm ''Yogi Bear And The Magical Flight Of The Spruce Goose'' had Paul Winchell--Dick Dastardly's original voice--as Dread Baron.
* ''WesternAnimation/LegendOfTheThreeCaballeros'' sees a few replacements:
** Regarding the show's title characters, while Creator/TonyAnselmo still voices Donald as always, Panchito and Jose are voiced by Jamie Camil and Eric Bauza rather than Creator/CarlosAlazraqui and Rob Paulsen.
** Ari the Aracuan Bird is voiced by Dee Bradley Baker instead of Frank Welker.
** Scrooge [=McDuck's=] brief cameo in the penultimate episode of season 1 sees him voiced by Eric Bauza rather than John Kassir (who first voiced him on ''WesternAnimation/MickeyMouse2013'' after Alan Young died) or David Tennant (since the show started production before ''WesternAnimation/DuckTales2017'').
* An absolute necessity with ''WesternAnimation/TheLegendOfVoxMachina''; since it's an animated adaptation of a TabletopGame/DungeonsAndDragons [[WebVideo/CriticalRole campaign]] where everyone except the members of Vox Machina is voiced by Creator/MatthewMercer. In the animated adaptation these roles are filled by a wide array of voice actors, though Matt still voices Trinket, Sylas Briarwood, Craven Edge, Orthax, Umbrasyl the Hope Devourer, and several background characters.
* ''WesternAnimation/LetsGoLuna'':
** Andy used to be voiced by Jaiden Cannatelli, but was replaced by Evan O'Donnell in 2020.
** Leo was voiced by Aidan Wojtak-Hissong for 8 episodes, then he was replaced by Shayle Simons for the rest of the series.
** While Creator/JudyGreer used to voice AND sing for Luna, she was eventually replaced by Creator/ErinFitzgerald for Luna's singing voice. And then Fitzgerald was permanently replaced by Liane de Lotbinière.
* On ''WesternAnimation/TheLionKing1994'' RecycledTheSeries ''WesternAnimation/TimonAndPumbaa'', Timon had three voice actors over the course of the series, including original actor Nathan Lane in nine of the episodes. Exactly ''when'' the transitions took place is undocumented, except for Creator/QuintonFlynn, who is mentioned as only being in the first season. Also, nearly every character who carried over from the movies was re-cast except for Pumbaa, Ed the hyena and Rafiki.
* Two of the four Russian dub voices for ''WesternAnimation/LittlestPetShop2012'' were replaced after season 2, with only Zoe, Pepper and Russell retaining their original voices. The cast changes are:
** Lina Ivanova replaces Elena Čebaturkina (Blythe, Minka and Penny Ling)
** Vasiliy Zotov replaces Yevgeniy Valts (Sunil and Vinnie)
* ''WesternAnimation/LoonaticsUnleashed'':
** The villain Massive was originally voiced by Creator/MichaelClarkeDuncan, but his appearance in "The Hunter" had Massive voiced by Creator/KevinMichaelRichardson.
** Minor character Mr. Leghorn debuted in the episode "Stop the World, I Want to Get Off", where he was voiced by Bill Farmer. For his second and final appearance in "The Music Villain", he was instead voiced by Creator/RobPaulsen.
* ''WesternAnimation/TheLooneyTunesShow'':
** Speaking of Mel Blanc's ''Looney Tunes'' characters being vocally replaced, this series only has Creator/JuneForay playing Granny. Creator/StanFreberg was going to voice Pete Puma, but was replaced at the last minute with Creator/JohnKassir, and the difference is very noticeable. The rest of the characters (most of which were voiced by either Creator/MelBlanc, Arthur Q. Bryan, Kent Rogers, or Bea Benaderet -- all of whom have long since died) now have these actors as their voice artists:
*** Creator/JeffBergman as Bugs Bunny, Daffy Duck, Foghorn Leghorn, Sylvester, and Tweety.
*** [[Series/SaturdayNightLive Fred Armisen]] as Speedy Gonzales.
*** Creator/KristenWiig as Lola Bunny.
*** Creator/BobBergen as Porky Pig. He would also voice Tweety later on.
*** Creator/EricBauza (John K.'s replacement for Creator/BillyWest on ''Ren and Stimpy's Adult Party Cartoon'') as Marvin the Martian. He would later take over Bergman's roles as Bugs and Daffy and Bergen as Porky in the late 2010s-early 2020s.[[note]]Though Bergman would voice Bugs again in ''Film/SpaceJamANewLegacy'', which came out in 2021, while Bauza still voiced Daffy and Porky.[[/note]]
*** Creator/{{Jim Cummings|1952}} as The Tasmanian Devil (continuing his role as Taz since ''WesternAnimation/TazMania'' and ''WesternAnimation/DuckDodgers'') and Beaky Buzzard, with Creator/FredTatasciore occasionally filling in for Cummings as Taz, save for ''Film/LooneyTunesBackInAction'' where Cummings was [[TheOtherMarty overdubbed by]] Creator/BrendanFraser during post-production.
*** Jennifer Esposito as Tina Russo (who herself was Darrined by Annie Mumolo in the second season).
*** Jess Harnell as one half of the Goofy Gophers (with Creator/RobPaulsen as the other half).
*** Creator/MauriceLaMarche as Yosemite Sam, with Fred Tatasciore once again filling in for him when need be.
*** Creator/BillyWest as Elmer Fudd.
*** Jim Rash as Cecil Turtle.
*** Ben Falcone as Henery Hawk.
** ''Looney Tunes: Rabbit Run'', a movie that acts as a spiritual successor, has writer/actress Rachel Ramras voice Lola. Jess Harnell also replaces John Kassir as Pete Puma.
* The same thing happened with the ''WesternAnimation/LooneyTunes'' characters, who have had many different voice actors after Creator/MelBlanc died (aside from Granny and Witch Hazel, of course).
** An interesting example involving Blanc. The character of Elmer Fudd was originally voiced by (and physically modeled after) portly actor Arthur Q. Bryan. In the classic "What's Opera Doc?" Bryan voiced Fudd as usual, except, during the part where Fudd summons various types of weather to attack Bugs, the word "Smog!" was done by Blanc. Hal Smith took over for a while following Bryan's passing, and then Mel Blanc took over permanently, and is now voiced by a number of voice actors in different media.[[note]]Blanc actually regretted taking over Elmer from Bryan, feeling it was disrespectful to copy another actor's voice, which is why Elmer does not appear on Blanc's "Speechless" lithograph.[[/note]]
** Porky was originally voiced by Joe Dougherty, who actually had a stutter and was fired because he couldn't keep it under control long enough to stay in character; said stutter also resulted in several audio tracks running on so long that they were thrown out for being unusable. When Mel Blanc took over, the character kept his trademark stutter but in a much more restrained fashion, allowing Blanc to remain in character.
** Beaky Buzzard was originally voiced by Kent Rogers in his first two cartoons, "WesternAnimation/BugsBunnyGetsTheBoid" and "WesternAnimation/TheBashfulBuzzard", but following his tragic death in a training exercise during World War II, Mel Blanc voiced him in his last two appearances, "The Lion's Busy" and "Strife with Father".
** Granny and Witch Hazel were originally voiced by Bea Benaderet before Creator/JuneForay stepped in (Benaderet had done many shorts as Granny, but only did "Bewitched Bunny" as Hazel). June Foray herself was replaced as Granny in the 1960s by Joan Gerber and Ge Ge Pearson for one short each, but returned as the character in all further productions until the aforementioned ''Looney Tunes Show'', after which Creator/CandiMilo took over as the character.
** "Dork Age" characters Merlin the Magic Mouse and his sidekick Second Banana were voiced by Daws Butler in their first short, then by Larry Storch in the other four.
* ''WesternAnimation/{{Lucky Luke|1983}}'': In French, Jacques Thébault (who dubbed James West in ''Series/TheWildWildWest'') replaced Daniel Ceccaldi (''[[WesternAnimation/LuckyLukeBalladOfTheDaltons Ballad of the Daltons]]'') as ComicBook/LuckyLuke. Ceccaldi himself had replaced Marcel Bozzuffi after ''[[WesternAnimation/LuckyLukeDaisyTown Daisy Town]]''.
* In the transition from the ''WesternAnimation/{{Madagascar}}'' films to ''WesternAnimation/ThePenguinsOfMadagascar'', some of the characters common to both franchises changed voice actors. Two of the three lemurs traded out their celebrity [=VAs=] because it would be too expensive to keep them: Danny Jacobs replaced Creator/SachaBaronCohen as King Julien, and Creator/KevinMichaelRichardson replaced Creator/CedricTheEntertainer as Maurice. However, Creator/AndyRichter retained his role as Mort. ''WesternAnimation/AllHailKingJulien'', a Creator/{{Netflix}} spinoff begun in December 2014, also uses Jacobs, Richardson, and Richter for the lemurs.
** Kowalski and Private are an interesting inversion of how this trope is normally handled: originally voiced by Creator/DreamWorksAnimation staff (animator Chris Miller and editor Chris Knights, respectively), they "upgraded" to professional voice actors Creator/JeffBennett and James Patrick Stuart on the series. (However, Creator/JohnDiMaggio stayed as Rico.) With the [[RecursiveAdaptation movie]] ''WesternAnimation/PenguinsOfMadagascar'' based on the show in late 2014, Kowalski and Private reverted to their movie voice actors, while Conrad Vernon (who voiced Mason the chimp in the original franchise and TV series) took over as Rico. [[spoiler:Also, Danny Jacobs voices Julien again in TheStinger.]] The only penguin whose voice actor has never changed is Skipper, who has always been voiced by animator Tom [=McGrath=] (although for the first movie, he was a PermanentPlaceholder for a then-recently deceased Robert Stack).
** The Brazilian Portuguese dub of ''WesternAnimation/ThePenguinsOfMadagascar'' changed dubbing cities from Rio de Janeiro to São Paulo after a few episodes.
** In European French, not including the video games, Maurice and Mort have had three voice actors each across the franchise. Maurice was voiced by Creator/MarcAlfos in the theatrical trilogy (before he died in 2012), Creator/PaulBorne (in a few TV specials released after Alfos' death), and Creator/EmmanuelCurtil (both TV series). Mort has been voiced by Creator/EmmanuelGarijo (all the movies/specials), Maël Davan-Soulas (in the Penguins TV series), and Creator/DonaldReignoux (in later seasons of ''Penguins'' and ''All Hail King Julien'', because Davan-Soulas had moved to Canada).
** In Italian, ''Madly Madagascar'' has a completely different voice cast compared to the movies, the other specials and ''The Penguins of Madagascar'', and ''All Hail King Julien'' features a third different voice cast. King Julien himself switched from Oreste Baldini to Alberto Bognanni to Ruggero Andreozzi because of this. If you count the video game cast of the first movie, then that (Creator/LucaBottale) makes four Italian King Juliens.
* The 2010's WesternAnimation/{{Marvel Universe|DisneyXD}} animated series (''WesternAnimation/{{Ultimate Spider|Man2012}}-Man'', ''WesternAnimation/AvengersAssemble'', ''WesternAnimation/HulkAndTheAgentsOfSMASH'', and ''WesternAnimation/{{Guardians of the Galaxy|2015}}'') has seen this:
** Creator/TomKenny voiced Curt Connors/The Lizard in the pilot episode of ''Ultimate Spider-Man'', but from "The Iron Octopus" onwards, the role was handed over to Creator/DeeBradleyBaker (reprising the role from ''VideoGame/SpiderMan2000'', ''VideoGame/SpiderMan2EnterElectro'', and ''WesternAnimation/TheSpectacularSpiderMan''). Also, the Scorpion was initially voiced by Creator/DanteBasco, who was replaced by Creator/EricBauza in Season 4.
** In ''Avengers Assemble'', Iron Man was voiced by Creator/AdrianPasdar. However, beginning in Season 4, Creator/MickWingert took over the role. Additionally, ComicBook/AntMan was voiced by Grant George in Seasons 1-3, and by Creator/JoshKeaton from Season 4 onward. In season 4, Howard Stark is now voiced by Creator/CharlieSchlatter instead of [[Series/SeventhHeaven Stephen Collins]], likely because of the recording of Collins admitting to now ex-wife Faye Grant to molesting several underaged children, which also resulted in Collins a case of TheOtherMarty, as Disney had his lines redubbed by Creator/TroyBaker.
** Creator/PhilLaMarr had reprised his ''WesternAnimation/TheAvengersEarthsMightiestHeroes'' role as JARVIS, but was then replaced by Creator/DavidKaye. Hercules was voiced by Townsend Coleman in ''Hulk and the Agents of S.M.A.S.H.'', but his appearance in ''Assemble'' sees him voiced by Creator/MatthewMercer.
** ComicBook/WerewolfByNight was originally voiced by Ross Lynch, then later by Creator/NolanNorth.
** The Guardians of the Galaxy got hit with this hard as Drax is the only character who hasn't changed voices (Creator/DavidSobolov still voices him). Creator/KevinMichaelRichardson voicing Groot was unavoidable with Creator/MichaelClarkeDuncan's passing. Rocket went from Creator/BillyWest to Creator/SethGreen to Creator/TrevorDevall, Star-Lord went from Creator/ChrisCox to Creator/WillFriedle, and Gamora went from Creator/NikaFutterman to Creator/VanessaMarshall, but given how the voices sound, as well as the designs for their own cartoon and seen on the ''Avengers Assemble'' episode "Widow's Run" (and how they were written in said episode), this could be seen an attempt to make things closer to the ''Film/{{Guardians of the Galaxy|2014}}'' movie and hence closer to Creator/BradleyCooper, Creator/ChrisPratt, and Creator/ZoeSaldana, respectively. Within [[WesternAnimation/GuardiansOfTheGalaxy2015 the Guardians' own series]], Jonathan Adams also replaced James C. Mathis, III as Ronan and despite voicing Rhomann Dey, Creator/JeffBennett is also replaced as the Collector and Grandmaster by, respectively, Creator/TomKenny and Creator/JasonSpisak. James Urbaniak replaces Creator/ReneAuberjonois as Ebony Maw. Vanessa Marshall also replaced Creator/CreeSummer as Star-Lord's mother, Meredith Quill.
** The Wrecking Crew also underwent this. Wrecker went from being voiced in ''Ultimate Spider-Man'' and ''Avengers Assemble'' by Creator/JohnDiMaggio to Creator/SteveBlum (who reprised his role as Wolverine) in Season 1 of ''Agents of S.M.A.S.H.'' and Creator/FredTatasciore (who reprises his role as the Hulk in all three) in Season 2. Creator/KevinMichaelRichardson voiced Bulldozer in ''Ultimate'', Creator/TravisWillingham (who also voices Thor) voiced him in ''Avengers Assemble'', Creator/BenDiskin (who voiced Skarr) voiced him in ''Agents of S.M.A.S.H.'' Chi [=McBride=] (who voices Nick Fury) voiced Thunberball in ''Ultimate Spider-Man'', but then Fred Tarasciore [[RoleReprise reprised]] [[VideoGame/MarvelUltimateAlliance the role]] in ''Assemble'' and Season 1 of ''S.M.A.S.H.'' and Jonathan Adam in Season 2. Adams also replaced Creator/CamClarke (who voiced the character in ''Ultimate Spider-Man'' and ''Assemble'') as Piledriver in ''Agents of S.M.A.S.H.''
** In the ''Assemble'' episode "Spectrums", the Nightmare versions of Ultron and the Winter Soldier were voiced by Creator/FredTatasciore and Creator/RogerCraigSmith, rather than Creator/JimMeskimen and Bob Bergen, respectively. Additionally, pre-Winter Soldier Bucky was voiced by Creator/RobbieDaymond in "Saving Captain Rogers" and Season 5 sees Bucky voiced by Creator/MattLanter.
** In ''Ultimate Spider-Man'', Klaw was voiced by Creator/MattLanter. In season 3 of ''Avengers Assemble'', he's voiced by David Shaughnessy. In Season 5 of the latter, he'll be voiced by his ''LEGO Marvel Super Heroes - Black Panther: Trouble in Wakanda'' voice actor, Creator/TrevorDevall. Likewise, Daisy Lightfoot, the voice actress for Shuri in the LEGO special, will replace Creator/KimberlyBrooks in the role.
** As both ''Guardians'' season 3 and season 5 of ''Assemble'' seems to have swapped out ''Ultimate Spider-Man'' for ''WesternAnimation/MarvelsSpiderMan'', a lot of the cast of the latter, including Creator/RobbieDaymond as Spidey himself and Creator/TroyBaker as Kraven, could fall under this.
* When ''WesternAnimation/MaxAndRuby'' got UnCanceled in 2009, Ruby, Martha, Roger, Mr. Huffington and Max were given new voices. The rest of the characters remained the original voice actors such as Louise and Max and Ruby's grandmother.
* Before ''WesternAnimation/MegasXLR'' became a full-fledged series, the voice of Gorrath was Wrestling/MickFoley (yes, ''[[Wrestling/{{WWE}} that]]'' Mick Foley) in the short "Lowbrow". When "Lowbrow" was reworked into the first episode of ''WesternAnimation/MegasXLR'', Creator/ClancyBrown took over as Gorrath's voice.
* Roy Halee was the singing voice of WesternAnimation/MightyMouse in the original Terrytoons shorts that pitted him against [[DastardlyWhiplash Oil Can Harry]]. When he took on a speaking voice in the titles and bumpers of ''Mighty Mouse Playhouse'', (as well as three TV-budget cartoons later), Terry storyman Tom Morrison took on the voice. Later shows saw Lou Schiemer (uncredited) in the Filmation series and Patrick Pinney in the Bakshi reboot as Mighty Mouse's voice.
* ''WesternAnimation/MickeyMouse'':
** On ''WesternAnimation/MickeyMouseClubhouse'', Mickey's voice actor, Creator/WayneAllwine, died in 2009. As such, the role was recast with Bret Iwan, who has voiced him in almost all media since then.
** ''WesternAnimation/MickeyMouse2013'':
*** Mickey is voiced by Creator/ChrisDiamantopoulos instead of Bret Iwan.
*** Scrooge's appearances after "Duck the Halls" has him voiced by John Kassir due to Alan Young's death.
** ''WesternAnimation/MickeyAndTheRoadsterRacers'':
*** Due to being a regular in ''four'' cartoons at the time, as well as working on video game appearances like ''Kingdom Hearts'', Donald is voiced by Daniel Ross instead of Tony Anselmo.
*** Minnie was voiced by Russi Taylor during the show's run but after she passed away in 2019 during production, she was recast with Creator/KaitlynRobrock who voiced her in the episodes that Taylor did not record her lines for. Robrock currently voices her in all media since then.
** ''WesternAnimation/MickeyMouseFunhouse'':
*** Due to Creator/TressMacNeille being too busy with other projects, her roles were recast in Seasons 2 and 3 with Creator/DebraWilson as Daisy and Jan Johns as Chip.
*** After Will Ryan died in 2021, Brock Powell succeeded him as Willie starting in "Tooth or Consequences!".
* ''WesternAnimation/MiraculousLadybug''
** Tiffany Hofstetter and Matthew Géczy (remember him from ''WesternAnimation/CodeLyoko''?) were the placeholder voices for Ladybug and Cat Noir respectively. Geczy also voiced Jagged Stone in the original French version.
** Creator/RebaBuhr replaces Erin Fitzgerald as Rose and Juleka in the ''Tales from Paris'' webseries and the main show from season 2 onwards.
** Creator/AnneYatco replaces Creator/PhileceSampler as Sabine Cheng beginning at Season 4 following the latter's death in 2021.
*** Anne Yatco also replaces Philece Sampler as Olga Mendeleiev in Season 5.
** If Ezra Weisz’s Instagram feed is any indication, then season 2 has replaced Matthew Mercer as Ivan and Creator/CassandraLeeMorris has replaced Marieve Herrington as Sabrina, in addition to the above-mentioned Reba Buhr.
** Starting [[https://mobile.twitter.com/childishgamzeno/status/1309638415420334080 with]] "Miraculous New York: United [=HeroeZ=]", Creator/ZenoRobinson replaces Creator/BenDiskin as Nino.
** In Season 4...
*** Zeno Robinson also replaces Ben Diskin as Max.
*** Creator/LaurenLanda replaces Cassandra Lee Morris as Sabrina and Pollen.
*** Creator/AlejandroSaab replaces Creator/KyleMcCarley as Marc. He also replaces Creator/VicMignogna as Jalil in Season 5.
* ''WesternAnimation/{{Mixels}}'':
** Creator/RodgerBumpass replaced Creator/FredTatasciore for Major Nixel in "Mixel Moon Madness". Creator/PeterJason ended up replacing Rodger in "A Quest for the Lost Mixamajig" and onwards.
** King Nixel was originally voiced by Phil Hayes in "Mixel Moon Madness", and was also replaced in "A Quest for a Lost Mixamajig", this time by Creator/SteveBlum.
** Kuffs is another that was voiced by Phil Hayes (in "Every Knight Has Its Day"), but was replaced as well by Creator/SteveBlum in "Nixel, Nixel, Go Away".
* ''WesternAnimation/MollyOfDenali'':
** In Season 2, Tooey is now voiced by Zane Jasper instead of Sequoia Janvier.
** Due to Taran Kootenhayoo's [[DiedDuringProduction death]], Randall is now voiced by Jared Ager-Foster.
* In Creator/{{Pixar}}'s ''WesternAnimation/MonstersUniversity'', Mr. Waternoose was played by Creator/KelseyGrammer due to the death of Creator/JamesCoburn (though his scene was [[DeletedScene cut from the film]]).
* ''[[Literature/TheMoomins Moominvalley]]'': Since season 3, Moomintroll is voiced by Jack Rowan instead of Creator/TaronEgerton.
* Jay Johnston is missing from some of the third season ''WesternAnimation/MoralOrel'' episodes, so some of his characters (like Coach Stopframe and Miss Censordoll) are voiced by David Herman and Scott Adsit, presumably because he was busy with ''Series/TheSarahSilvermanProgram''. He still voices Joe in all of his appearances, and returns for ''Beforel Orel''.
* ''WesternAnimation/MuppetBabies1984'' had a few cases of the trope. After Howie Mandel left the show in 1985, his roles of Baby Animal and Bunsen were given to Dave Coulier, while Frank Welker took on voicing Baby Skeeter. Meanwhile, Camilla the Chicken was initially voiced by Frank Welker, but was later voiced by Dave Coulier and then by Russi Taylor.
* ''WesternAnimation/MyLittlePonyTales'': Patch's original voice, Venus Terzo, was replaced with Brigitta Dau after 16 episodes.
* ''Nicktoon World News'':
** In the shorts (a series of segments during commercial breaks on Nickelodeon from 2000 to 2001 that were either used to give out information on various Nicktoons or announce the shows up next) hosted by Henry and June from ''WesternAnimation/KaBlam'', June was not played by Julia [=McIlvaine=], who played her in the show as well as the previous blocks hosted by the duo (Henry and June's Summer Jam, 101% Whizbang, and U-Pick Fridays). Her voice actress in ''Nicktoon World News'' is unknown.
** Larry had a different voice actor in the ''Life With Loopy'' pilot "Goldfish Heaven" (which aired as the sixth episode of the show). However both his pilot voice actor and regular voice actor remain unknown.
* In season 2 of ''WesternAnimation/NatureCat'', Ronald is no longer voiced by Creator/KenanThompson due to him leaving after Season 1 to focus on other projects, and is now voiced by Chris Knowings.
* ''WesternAnimation/{{Ninjago}}'' for the Hungarian dub: Samukai's voice changed from the pilot to the first season, but seasons 1 and 2 were mostly consistent. S3, being produced years later, recast Pythor (now voiced by minor villain Captain Soto's original actor), Sensei Dareth and some others. S4 was dubbed by a new team: Lloyd Garmadon and Sensei Dareth, as well as everyone who wasn't a main character from S1 and S2, got recast, including new characters introduced in S3. Pythor's original voice actor returned, using the exact same voice... for a random other snake, with Pythor being recast ''again'' as his 2nd VA was now voicing an unrelated character (Neuro, which meant that Captain Soto also got a new voice for his cameo). A similarly confusing case befell Kruncha and Nuckal: in S4, Kruncha's original actor was cast as another character (Bolobo), so Nuckal's original voice took over as Kruncha, and Nuckal got a completely new voice. Also for the English dub: Lloyd was voiced by Jillian Michaels for the first seven seasons, then Sam Vincent took over the role as of Season 8. Cole was voiced by the late Kirby Morrow just until Season 14, then he was replaced by Andrew Francis in the final season.

[[folder:O-R]]
* In the ''WesternAnimation/OhYeahCartoons'' short "Max and his Special Problem", the title character was voiced by the short's creator Dave Wasson. The sequel short, "Max and the Pigeon Incident", instead had Max voiced by Vincent Waller.
* ''WesternAnimation/OKKOLetsBeHeroes''
** K.O. was voiced by Creator/StephanieNadolny in the pilot and mobile game, but eventually recast as Creator/CourtenayTaylor. Due to the difference between the order of voice recording and airing order, K.O.'s voice changed erratically between the two during the shorts and the first thirteen episodes.
** Mena Suvari voiced Enid in the original pilot and the mobile game. Come the minisodes and the full series, Enid is now voiced by Creator/AshlyBurch.
** The standard robot enemies in the mobile game were voiced by the game's developers, while the final show uses different [=VAs=].
** Tessa Auberjonois voices [[WesternAnimation/CaptainPlanetAndThePlaneteers Dr. Blight]] instead of Creator/MegRyan or the late Creator/MaryKayBergman.
** From the Hungarian dub: the second "batch" of dubbed episodes replaced Dandy and Potato (the latter originally voiced by a boy, now a girl), and sadly Mr. Gar's voice actor suddenly passed away shortly after recording, meaning he will be replaced too, with his final episodes having been released posthumously.
* ''ComicStrip/{{Peanuts}}''
** The voices for the characters in the animated specials change drastically. Almost every other TV special changes at least one actor. This is due to the fact that real children are always used. Many fans are surprised that the franchise hasn't switched to an all female cast that sound like kids. Covering all the recasts wouldn't be practical, but to put things in perspective, Charlie Brown and Lucy have both had ''27'' different voice actors since the franchise began. Linus is a bit more lucky, being recast only... 15 times. Snoopy is the only one who had consistent voice actor throughout: the original director Bill Melendez (in ''WesternAnimation/ThePeanutsMovie'' they used his archive recording for Snoopy's vocal effects).
** This got worse in the Latin American dub, when they not only changed voice actors, but also even dubbing ''countries''.
* For the first three seasons of ''WesternAnimation/PepperAnn'', Nicky's boyfriend Stewart was voiced by Creator/LukePerry, from season 4 onwards he was voiced by Creator/CamClarke.
* ''WesternAnimation/ThePinkPanther'':
** The Commissioner in ''The Inspector'' (which aired alongside the cartoons) had FOUR different voice-actors during its run. Larry Storch initially did his voice in the first two shorts, then Creator/PaulFrees took over for the most of the run. Mark Skor did his voice in one cartoon, and finally, Marvin Miller took over for his final appearances.
** Incidentally, Creator/PatHarringtonJr did Sgt. Deux-Deux's voices for all of his appearances except one: Don Messick did his voice in his final appearance, "La Feet's Defeat". He sounded nothing like the original.
** Also, when the Pink Panther and Inspector first aired on Creator/{{NBC}}, the theatrical cartoons were being aired along with 30-second animated bumpers featuring the characters. The Inspector's and Sgt. Deux-Deux's voices were being done by Marvin Miller for those bumpers.
** While normally silent, the Panther himself spoke in two theatrical cartoons, each with a different voice--"Pink Ice" (Rich Little) and "Sink Pink" (Creator/PaulFrees). In the 1993 Panther reboot, the Panther spoke continuously with the voice of Creator/MattFrewer.
* ''WesternAnimation/{{Pocoyo}}'': Very noticeable in the Castilian Spanish version with Pocoyo, even though he only ever speaks a few words. His new voice actress in the 2016 reboot makes him sound very high-pitched and girlish as opposed to the original series, where he sounded more like an actual male toddler.
* ''WesternAnimation/{{Popeye}}'':
** Jack Mercer is widely known as the voice of Popeye. He was certainly the most prolific, doing double duty as a storyman for the series. Prior to that, William Costello was Popeye's voice. During a spell in the 1940s when Mercer was doing Navy duty, Popeye would be voiced by Harry Welch, Jackson Beck (the voice of Bluto at the time), [[CrossDressingVoices and]] Mae Questel (voice of Olive Oyl). Following Mercer's death in the 80s, Popeye would be voiced by Maurice [=LaMarche=] (''Popeye And Son''), Billy West, and (currently) Tom Kenny.
** Olive's voices have been Mae Questel (her most prolific voice), Margie Hines, Bonnie Poe, Marilyn Schreffler (1978-82 plus 1987's ''Popeye And Son''), Tabitha St. Germain, Amy Adams, and currently Grey [=DeLisle=].
** William Pennell originated the voice of Bluto, while Jackson Beck became his more recognizable voice, doing it all the way through 1972's feature ''Popeye Meets The Man Who Hated Laughter'', where Bluto had since been renamed Brutus. Gus Wickie, Pinto Colvig, Dave Barry, Gary Chalk, Allan Melvin, and even Jack Mercer has also been Bluto/Brutus' voice.
* When the 1985 ''[[WesternAnimation/PoundPuppies1980s Pound Puppies]]'' television special was made into a series, some characters were either [[DroppedAfterThePilot dropped]] or recast, to the point that Cooler (who was voiced by Dan Gilvezan) was the only main character to have his original actor reprise their role in the television series.
** The character The Nose was renamed Nose Marie and was voiced by Ruth Buzzi instead of Joanne Worley.
** Howler didn't speak in the original special, but his howls were provided by Frank Welker. The series had him SuddenlySpeaking and had Robert Morse replace Frank Welker.
** Creator/NancyCartwright replaced Adrienne Alexander as the voice of Bright Eyes.
* ''WesternAnimation/PoundPuppies2010'':
** Leonard [=McLeish=]'s brother-in-law the Mayor was originally voiced by Dabney Coleman, but by the second season Coleman was replaced by Creator/JohnLarroquette.
** The FKD (Free Kid Database) was usually voiced by Creator/TressMacNeille, but was instead voiced by Creator/LaurenTom for the episodes "Hail to the Chief" and "Back in Action".
* In ''WesternAnimation/PrincessGwenevereAndTheJewelRiders'', Gwenevere was voiced by Kerry Butler in the first season, and by Creator/JeanLouisaKelly in the second season.
* ''WesternAnimation/PuppyDogPals'':
** [[https://variety.com/2020/tv/news/tnts-snowpiercer-tv-news-roundup-1234798138/amp/?__twitter_impression=true Due]] to Isaac Ryan Brown and Sam Lavagnino going through puberty, Bingo and Rolly were voiced by EJ Williams and Gracen Newson for the last two seasons.
** In Season 4, Mrs. Claus was voiced by Creator/GreyDeLisle rather than Wendi [=McLendon=] Covey.
** Crandall The Crab was voiced by Nick A. Fisher in the Season 4 episode "Runaway Wedding Ring" instead of Julian Edwards who previously voiced him in the Season 3 episode "Seen Any Seashells". Possibly due to the latter being too busy with voicing Mo.
* ''WesternAnimation/TheRaccoons'' had several Other Darrins:
** In the original specials, the characters of Dan the Ranger and Melissa Raccoon were always voiced by the musical guests; Dan was voiced by Rupert Holmes in ''The Christmas Raccoons'', Leo Sayer in ''The Raccoons on Ice'', and John Schneider in ''The Raccoons and the Lost Star'', while Melissa was voiced by Rita Coolidge in the first two and Dottie West in the third. In the made-for-video special ''The Raccoons: Let's Dance!'', series creator Kevin Gillis did Dan's few lines (uncredited), while Melissa did not speak. In the first season of the series, Murray Cruchley voiced Ranger Dan, while Linda Feige voiced Melissa. Between seasons 1 and 2, Dan and the other human characters disappeared from the show, and Linda Feige left and was replaced by [[Anime/SailorMoon Susan Roman]]. When Roman took over the role of Melissa, her interpretation actually changed the character of Melissa, who became spunkier, more youthful and more outspoken (while the character had previously been much more soft-spoken and motherly).
*** Interestingly enough, in the season 2 {{clip show}} episode "Time Trap!", Susan Roman replaced Linda Feige's dialogue in clips from season 1 (since the episode involves Cyril Sneer traveling back in time and changing history, this was obviously necessary in order to match the new scenes).
** Ranger Dan's kids, Julie and Tommy, were originally voiced by Tammy Bourne and Hadley Kay in the specials. In the first season of the series, puberty had set in for both, so they were replaced by Vanessa Lindores and Creator/NoamZylberman (who would go on to voice Bentley Raccoon in later seasons).
** The specials were narrated by Creator/RichLittle, while Geoffrey Winter took over the narrator duties in the series.
** In the specials, Cedric Sneer was originally voiced by Fred Little (yes, he and Rich are related); he was replaced by Marvin Goldhar in the series. This is seen as a good change by most fans, as Fred Little's interpretation of the character was extremely whiny and overflowing with {{Narm}}. During the series, Cedric gradually became more self-confident as Goldhar moved away from imitating his predecessor.
** Cyril Sneer's pig henchmen were introduced in ''The Raccoons and the Lost Star'', voiced by Nick Nichols, Len Carlson and Fred Little (though Nichols, being the leader, was usually the only one to speak by himself rather in unison). In the series, Len Carlson took over Fred Little, and eventually developed Pigs Two and Three into separate characterizations (where they were originally interchangeable). In 1989, Nick Nichols' poor health and eventual death led to the recasting of Keith Hampshire as Pig One early in the season. Hampshire's voice for the character never really moves beyond an impersonation of the original (though he got a little better by the final episodes).
** Bentley Raccoon was originally voiced by Creator/NoamZylberman. Zylberman was going through puberty during the voice recording for Season 5, and so was replaced by Stuart Stone. (You can really tell in Zylberman's last episodes, in which his voice is considerably deeper.) Some fans argue that the actual character deteriorated considerably with the recast; while he had gradually matured throughout the series, suddenly he was an annoying, whiny kid again.
** In a musical example of The Other Darrin, Luba was the featured female singer in Season 1, while Lisa Lougheed came in as the featured singer beginning in Season 2 and through the rest of the series. When Luba's songs from season 1 were used in later episodes (and on the "Evergreen Nights" album), they featured Lisa Lougheed's vocals tracked into the original mixes in place of Luba's.
* ''WesternAnimation/ReadyJetGo'':
** In Cousin Zerk's debut episode "Earth Mission to Moon", he was voiced by Ashleigh Ball. Subsequent episodes have him voiced by Meg Roe.
** In the TV Movie ''Back to Bortron 7'', ([[OutOfOrder which also happens to be part of season 2 even though season 1 was not complete at the time]]), Sydney and Mitchell (initially voiced by Dalila Bela and Spencer Drever, respectively) both got new voice actors: Vienna Leacock and David Raynolds respectively.
*** In "One Small Step", Mitchell got yet another new voice actor: Dylan Schombing.
** Sean was initially voiced by William Ainscough. In the final 7 ([[TwoShorts technically 14]]) episodes of Season Two, he was voiced by Grady Ainscough. In the Season Two finale ("Lone Star 2 - Rocket Kids!"), as well as a game on the PBS Kids website and the "One Small Step" movie, he's voiced by Glen Gordon (however, Grady was still credited in the case of the S2 finale).
* ''WesternAnimation/TheRealGhostbusters'':
** The characters of Janine, Peter and Winston all switched to new voice actors at around the third season. Reruns of episodes from the first two seasons even had the characters redubbed for consistency (although the DVD release uses the original versions). Janine's was the most interesting case, in that her original rather abrasive look/voice were drastically toned down when the switch happened (which was due to Laura Summer moving on with her career, and the character being toned down with Creator/KathSoucie as the voice), and this fact was then belatedly used as the plot in an episode, "Janine, You've Changed". It was {{retcon}}ned that Janine had made a [[DealWithTheDevil deal with an evil spirit]] to cause the change, only nobody noticed until a character accidentally came across "before and after" photographs.
** Funnily enough, by the time of the ''WesternAnimation/ExtremeGhostbusters'', she had reverted back to her old abrasive style, though it was yet ''another'' actress in the role (Pat Musick).
** Peter Venkman wound up recast from Lorenzo Music (the voice of Garfield the cat in most Garfield-related media, most notably ''WesternAnimation/GarfieldAndFriends'') to Dave Coulier (Joey on ''Series/FullHouse''), allegedly because Bill Murray had wondered why Music sounded nothing like him (although the person responsible for the change was the producer Joe Medjuck). Coulier would go on to voice Venkman when he appeared on the ''WesternAnimation/ExtremeGhostbusters'' episode, "Back in the Saddle".
** While Janine and Peter were recast with season 3, Arsenio Hall continued voicing Winston until the following season, when he left due to being busy with his talk show. Buster Jones (Doc from ''WesternAnimation/GIJoeARealAmericanHero'') was then cast as Winston, and voiced him for the remainder of his appearances.
** The Stay-Puft Marshmallow Man had his vocal effects provided by Frank Welker in season 2, but by Maurice [=LaMarche=] in season 3's "Sticky Business". Welker would then reprise Stay-Puft for his final cameo in season 5.
* ''WesternAnimation/ReBoot'':
** Played straight, parodied and {{lampshade|Hanging}}ded. When Bob returns from being lost in the net in Season 3, he has a new look and a new voice actor. In Season 4, a second Bob, supposedly the User's backup, with the original look and voice shows up, and Dot notes he sounds more like the "real" Bob. She nearly marries this Bob, but [[spoiler:of course he was [[TheDragon Megabyte]] in disguise using his new [[{{Pun}} Trojan]] [[ShapeShifting Horse]] [[MasterOfDisguise capabilities]].]]
** Played straighter with [[MinionWithAnFInEvil Hack]], who was originally voiced by Phil Hayes, but was changed to Creator/ScottMcNeil midway through season 2.
* ''WesternAnimation/{{Recess}}'':
** Most of the child characters were done by children, and all of the main six kids (save for Spinelli, who was voiced by a grown woman) were all done by kids. While the boys all kept their voices even after their actors went through puberty (except Gus, whose voice never broke), T.J. had to be replaced ''three'' times, because even after his voice actor went through puberty, the replacement voices they hired neither sounded right nor captured the spirit of the original. Ross Malinger played T.J. in the 1996 pilot (re-made into the first episode) and all of Season 1, Andy Lawrence (Joey Lawrence's younger brother) played him from Season 2 until the end of the show, and Myles Jeffrey played him in the two direct-to-video movies released two years after the series ended and in miscellaneous sports, such as station [=IDs=] for Creator/DisneyChannel[=/=]Creator/ToonDisney. Axel Alba voiced T.J.'s last appearance in the ''WesternAnimation/LiloAndStitchTheSeries'' crossover episode "Lax".
** Also, T.J.'s older sister, Becky, was played by Creator/MelissaJoanHart in the movie. In ''Taking the Fifth Grade'', she's replaced with Creator/TaraStrong.
* ''Literature/{{Redwall}}'' had this happen for Cornflower. Cornflower was voiced by a then-unknown Creator/AlisonPill in Season 1 but for Season 2 she was voiced by Melissa [=McIntyre=] instead.
* ''WesternAnimation/RegularShow'':
** Creator/JeffBennett voiced High-Five Ghost in his first two speaking roles, but show creator J.G. Quintel ([[ActingForTwo also the voice of Mordecai]]) took over not long afterward. However, Bennett has stayed on to voice background characters.
** On the Thanksgiving episode, Mordecai's parents were voiced by Creator/JenniferHale and Alistair Duncan. On the first episode that centered on Mordecai's relationship with his parents ("Maxin' and Relaxin'"), Mordecai's parents were voiced by [[Series/MarriedWithChildren Katey]] [[{{WesternAnimation/Futurama}} Sagal]] and [[Series/StElsewhere Ed Begley, Jr]]. The vocal change for Mordecai's mom is obvious, since she now sounds like a cheery Peg Bundy (or Turanga Leela in a good mood).
* ''WesternAnimation/TheRenAndStimpyShow'':
** Creator/JohnKricfalusi was the original voice of Ren. After Kricfalusi was fired over censorship issues and turning in late work, Creator/BillyWest took over the role of Ren [[ActingForTwo in addition to his role as Stimpy]] [[note]] Interestingly, Billy West has stated that he originally recorded both voices for a demo pitch to Nickelodeon, but when the show started production, John K. took the part of Ren for himself.[[/note]].
** In the short-lived ''[[WesternAnimation/RenAndStimpyAdultPartyCartoon Adult Party Cartoon]]'' spinoff, while John K. [[TheOriginalDarrin returned to his role as Ren]], Stimpy was voiced by Creator/EricBauza instead of Billy West. The reason for this was because Billy West hated working with John K., and he found the revival to be so bad that he thought working on it would damage his career.[[note]] It should be noted that, despite his negative experiences with the franchise, West doesn't actually hate working on ''Ren and Stimpy'' media. He reprised his role as Stimpy for the 2007 video game ''[[VideoGame/NicktoonsUnite Nicktoons: Attack of the Toybots]]'', and has stated that he would be reprising his roles as Ren and Stimpy in an upcoming reboot of the series.[[/note]]
* ''WesternAnimation/RickAndMorty'': Starting with the 7th Season, the titular duo are separately voiced by Ian Cardoni (Rick) and Harry Belden (Morty) after it came to light in January 2023 that Creator/JustinRoiland, [[ActingForTwo their]] original voice actor and series co-creator, was [[RoleEndingMisdemeanor charged with domestic abuse in 2020]], leading to Creator/AdultSwim subsequently firing him. Jon Allen also replaces him as Mr. Poopybutthole.
* ''WesternAnimation/{{Robotboy}}'': In Hungary, the entire cast was replaced beginning from season 2, likely thanks to an outcry over season 1 being handled by a cheap Romanian dubbing studio who gave most of the characters rather grating voices. In Tommy Turnbull's case, Gergo Bogdan voiced him in the first season. Later on in the series, Gergo was replaced by Tamas Markovics.
* ''WesternAnimation/RocketPower'':
** Squid went through four voice actors: Sam Saletta, Gary Leroi Gray, Matt Lane, and Sean Marquette. Apparently, they had to replace Sam because he was no longer able to voice the character after puberty but it's never really been said why the other actors were replaced.
** Twister has also been played by two people: Ulysses Cuadra (the son of Nicaraguan-born Spanish dubbing actor Ulises Cuadra) and Gilbert Leal.
* ''WesternAnimation/RockyAndBullwinkle'':
** The original series featured Creator/JuneForay as Rocky and Natasha, Bill Scott as Bullwinkle and Fearless Leader, Creator/PaulFrees as Boris and Captain Peter Peachfuzz, and William Conrad (of ''Series/{{Cannon}}'' fame) as the Narrator.
** A series of 1990's Taco Bell commercials featured Creator/FrankWelker as Bullwinkle, Creator/JoeAlaskey as Boris, and Creator/CoreyBurton as the Narrator. June Foray retained her original roles.
** [[Film/TheAdventuresOfRockyAndBullwinkle The 2000 feature]] still had June playing Rocky and Natasha, and now features Keith Scott (no relation to Bill) as Bullwinkle, Boris, Fearless Leader and the Narrator. In the real world, Boris, Natasha and Fearless Leader were played in the flesh by Creator/JasonAlexander, Creator/ReneRusso and Creator/RobertDeNiro respectively.
** The 2014 short from Creator/DreamWorksAnimation featured Creator/TomKenny as Bullwinkle, Robert Cait as Boris, Lauri Fraser as Natasha, Thomas Lennon as Fearless Leader, and Creator/StephenStanton as Captain Peachfuzz. June ''still'' played Rocky, in what would be her final role before her death in 2017.
*** Though Rocky was voiced by a different actress for a GEICO commercial featuring the [=DreamWorks=] versions of the characters.
** ''Peabody's Improbable History'': The original shorts featured Bill Scott as Mr. Peabody and Walter Tetley as Sherman. [[WesternAnimation/MrPeabodyAndSherman Their 2014 feature]] starred Creator/TyBurrell as Peabody and Max Charles as Sherman. For [[WesternAnimation/TheMrPeabodyAndShermanShow their Netflix series]], Charles reprises his role, while Peabody was now played by Chris Parnell.
** ''WesternAnimation/DudleyDoRight'' originally featured Bill Scott as Dudley, June Foray as Nell, Hans Conried as Snidely Whiplash, and Paul Frees as Inspector Fenwick and the Narrator (the latter role Frees alternated with Bill Conrad). For [[Ride/DudleyDoRightsRipsawFalls the theme park attraction]], Keith Scott played Dudley and Inspector Fenwick, while Creator/CoreyBurton played Snidely and the Narrator.
* ''WesternAnimation/RollingWithTheRonks'':
** The four-minute pilot episode "Welcome to the Ronx" had Mila voiced by Creator/NikaFutterman and Walter voiced by Creator/RinoRomano. For the series proper, they are instead voiced respectively by Creator/JessicaDiCicco and Scott Whyte.
** Creator/BillyWest replaces Creator/DeeBradleyBaker as the voice of Godzi the lizard halfway through the series.
* ''Literature/RottenRalph'' was adapted into two stop-motion animated specials titled ''The Taming of the Ralph'' and ''Not-So-Rotten Ralph'', which were then followed by a television series. The television series went with having the characters voiced by Canadian voice actors rather than American voice actors like the two specials, which resulted in such cast changes as Ralph himself going from Hal Rayle to Rick Jones and Ralph's cousin Percy being voiced by Daniel Brochu instead of Creator/CoreyBurton.
* ''WesternAnimation/{{Rugrats}}'':
** After Creator/ChristineCavanaugh retired from voice acting in 2001, Creator/NancyCartwright took over her role of Chuckie for the last two seasons of the show and ''WesternAnimation/AllGrownUp''. Creator/CandiMilo also briefly voiced the character in two video games following Cavanaugh's retirement.
** After the 1997 death of Grandpa Lou's first voice actor, David Doyle, Joe Alaskey replaced him.
** In his first appearance, Jonathan (Charlotte's assistant at work) was voiced by Rene Auberjonois. When he returned to the show, he was replaced by Creator/DanCastellaneta.
** Creator/ElizabethDaily also filled in for Creator/CreeSummer for a few episodes as Susie when Summer wasn't available.
** Tommy was voiced by Tammy Holbrook for the original pilot ("Tommy and the Great White Thing"), but when the pilot was made into a series, Elizabeth Daily was hired as Tommy's regular voice.
* In the first season of ''WesternAnimation/{{Rupert}}'', an AnimatedAdaptation of the British comic strip ''ComicStrip/RupertBear'' by Creator/{{Nelvana}}, the titular character was voiced by Ben Sanford. The remaining four seasons had Creator/JulieLemieux replace Ben Sanford as the voice of Rupert Bear.

[[folder:S]]
* ''WesternAnimation/SabrinaTheAnimatedSeries'':
** This happened when it became ''Sabrina's Secret Life''. Emily Hart (Melissa Joan Hart (the live-action Sabrina)'s younger sister) played her in the regular series, only to be replaced by Britt [=McKillip=] for the spin-off. Nick Bakay was replaced by Creator/MauriceLaMarche as the voice of Salem, and Hilda and Zelda got replaced as well (from both being voiced by Creator/MelissaJoanHart herself to being voiced by Moneca Stori and Jane Mortifee respectively). The only character without a voice switch was Harvey, whose voice actor continued doing his voice, but made his voice a little lower to cover up the fact that it had changed during puberty. The changes were due to Bunea Vista and Melissa Joan Hart no longer producing (as well as pre-production companies [[WesternAnimation/EekTheCat Savage Studios]] and [[WesternAnimation/{{Doug}} Jumbo Pictures]] leaving), leaving [=DiC=] by themselves to have to hire a new production and voice team.
** In the TV movie, ''Sabrina: Friends Forever'', where the "Secret Life" voice actors made their debuts, Louis Chirillo and Tina Bush voiced Salem and Zelda instead of Creator/MauriceLaMarche and Jane Mortifee respectively.
*** The Italian dub of ''Friends Forever'' replaces the whole regular cast... with the one from the live-action series. The original one came back for ''Secret Life''.
** If you want to go back to the [[WesternAnimation/SabrinaAndTheGroovieGoolies 70s adaptation of the Sabrina series]], the voices were, of course, different from the "Animated Series" counterparts. For instance Jane Webb (AKA Joanne Louise) voiced Sabrina ([[ActingForTwo and Hilda AND Zelda...]]) and Dallas [=McKennon=] did the purr sounds for Salem.
* As with the ''Avatar'' information above, the [[SamuraiJack/TropesSeason5 2017 revival]] of ''WesternAnimation/SamuraiJack'' has Aku voiced by Greg Baldwin because of Creator/{{Mako}}'s death, though this also falls under RoleReprise, as Baldwin has voiced the character before, in Cartoon Network's CrisisCrossover game ''VideoGame/FusionFall''.
* In ''WesternAnimation/TheSaveUms'', Noodle was voiced by Creator/MarkRendall in Season 1 and Creator/CameronAnsell in Season 2. However, because he was the only Save-Um to be Darrinned, this resulted in him having a squeaky voice while all the other Save-Ums' voices dropped ''very'' low.
* The voices for ''Franchise/ScoobyDoo'' have gone through a large roundabout over the years.
** Daphne was the first character in the series' history to be recast. Her original voice actress, Stefanianna Christopherson, left the show before the end of the first season of the original series (17 episodes) to move to New York to get married, and opted not to reprise her role for the second season. The role was recast with Heather North (the then roommate of Nicole Jaffe, the voice of Velma). North continued to voice Daphne in all media until 1998 (with the exception of ''WesternAnimation/APupNamedScoobyDoo'' from 1988-91, where she was voiced by Kellie Martin) when the character was recast again, this time with Creator/MaryKayBergman. Bergman committed suicide in 1999, after voicing Daphne for 3 direct-to-video movies. Since then, Grey [=DeLisle=] has voiced Daphne in all media (except for two DTV movies in 2002-2003 in which Heather North briefly returned).
** Velma was originally Nicole Jaffe up until the 1976 series, ''WesternAnimation/TheScoobyDooShow'' in which she declined to reprise her role, and the character went to Pat Stevens, who voiced Velma throughout the entire run of that show, as well as in the ''Scooby Goes Hollywood'' movie, her appearances in ''WesternAnimation/DynomuttDogWonder'', and the first 11 episodes of ''WesternAnimation/ScoobyDooAndScrappyDoo''. Velma was then infamously recasted with Marla Frumkin, who played Velma in the last four episodes of that series and two cameos throughout the 80's. From 1988 to 1991, the younger version of Velma was voiced on ''WesternAnimation/APupNamedScoobyDoo'' by Christina Lange. When Velma appeared in her normal form again in 1997, BJ Ward took over the role, and voiced Velma in all media until 2003 when Nicole Jaffe assumed the role again for two DTV movies, and from then until 2015, Mindy Cohn voiced Velma in pretty much all other media (doing a Nicole Jaffe impression), even being nominated for an Emmy for her voicework as Velma in 2005. Stephanie D'Abruzzo voiced Velma (as well as puppeteering her) in the 2013 direct-to-video puppet feature ''Film/ScoobyDooAdventuresTheMysteryMap''. In ''WesternAnimation/BeCoolScoobyDoo'', Velma is voiced by Creator/KateMicucci, who has since taken on the role of Velma full time.
** Shaggy was Creator/CaseyKasem from his debut until he quit the role in 1998 after refusing to voice the character in a Burger King commercial (since Kasem was an avid vegetarian). Creator/BillyWest briefly voiced Shaggy for ''Scooby-Doo on Zombie Island'' before the role was recast again in 1999 with Scott Innes. Kasem returned to voice Shaggy in 2002, and continued to voice him until his retirement in 2009 (though Scott Menville briefly played the character in ''WesternAnimation/ShaggyAndScoobyDooGetAClue'' when Kasem played Shaggy's uncle). Since then, Creator/MatthewLillard (who played Shaggy in the two live-action theatrical ''Scooby-Doo'' movies) has been the voice of Shaggy.
** As for Scooby-Doo himself, he was voiced by the late great Creator/DonMessick until his retirement in 1996. Hadley Kay briefly took over the role for ads, commercials, and his guest appearances on ''WesternAnimation/JohnnyBravo'' in 1997. Scott Innes then took over the role in 1998, and voiced Scooby in all media until 2002 when Creator/FrankWelker was cast. Welker has been the official voice of Scooby ever since.
** Creator/FrankWelker is the only actor to date to play ''regular'' Fred, but Carl Steven played a 10-year-old Fred in ''WesternAnimation/APupNamedScoobyDoo''.
** Scrappy's original voice actor, Lennie Weinrib[[note]]the same one who played Chet Boyle on ''WesternAnimation/WaitTillYourFatherGetsHome'' and was Timer the Cheese Guy[[/note]], left the franchise over pay concerns shortly after the original incarnation of ''WesternAnimation/ScoobyDooAndScrappyDoo'', and was replaced with Creator/DonMessick in [[WesternAnimation/TheScoobyDooAndScrappyDooShow pretty]] [[WesternAnimation/ScoobyDooMeetsTheBooBrothers much]] [[WesternAnimation/ScoobyDooAndTheGhoulSchool all]] [[WesternAnimation/ScoobyDooAndTheReluctantWerewolf media]] until the character was written off the franchise. When Scrappy re-appeared in later media such as a commercial for Cartoon Network (in which he grumbles about how little respect he gets at the studio), and his role as a villain in the live-action movie, Scrappy has been voiced by Scott Innes.
** ''WesternAnimation/{{Scoob}}'' opts for a CelebrityVoiceActor cast, which means most of the current ''Scooby-Doo'' cast were recast (''without'' notifying them, no less). While Scooby himself is still voiced by Frank Welker, Fred (who has been also voiced by Welker since the show's debut in 1969) has been recast with Creator/ZacEfron. WesternAnimation/{{Dynomutt|DogWonder}}, also voiced by Welker since his debut, has also been recast with Creator/KenJeong.
** ''WesternAnimation/{{Velma}}'' will similarly go with recasting the human members of Mystery Inc., with Velma voiced by Creator/MindyKaling, Shaggy (here known by his real name, Norville) by Creator/SamRichardson, Daphne by Creator/ConstanceWu, and Fred by Creator/GlennHowerton.
* In ''WesternAnimation/Sealab2021'', Captain Murphy was voiced by Harry Goz, who portrayed the character until his death in 2003. When Captain Murphy showed up a decade later in a two-part episode of ''WesternAnimation/{{Archer}}'', [[CharacterOutlivesActor he was now voiced by]] ''Series/MadMen'' star Creator/JonHamm. Though technically Archer's Captain Murphy (and there being a Sealab at all) was more a ShoutOut to ''WesternAnimation/Sealab2021'', Adam Reed being the creator of both shows and was entirely an InNameOnly reference.
* WesternAnimation/SecretSquirrel and Morocco Mole: Creator/MelBlanc and Creator/PaulFrees in the original, Creator/JessHarnell and Creator/{{Jim Cummings|1952}} in the 1993 retool on ''WesternAnimation/TwoStupidDogs''.
* ''WesternAnimation/SheepInTheBigCity'' had Lady Richington voiced by Ruth Buzzi in the pilot episode, with the rest of the series having Stephanie D'Abruzzo voicing her.
* ''WesternAnimation/TheSimpsons'':
** Parodied in the Season 10 episode "Homer to the Max" [[note]]The episode where Homer changes his name to "Max Power" after his name gets used for a bumbling sidekick character on a cop show -- that was originally a dashingly handsome sidekick in the pilot episode[[/note]], Homer looks over all the new mid-season replacement shows and points out a new animated series called "The Laughter Family", adding that TV networks love animated shows, "...because they don't have to pay the actors squat!"[[note]]This aired around the time that the show was facing a pay dispute from the voice actors and the FOX executives threatened to have all the original voice actors replaced with sound-alikes[[/note]] Ned Flanders then walks by the window and, in a noticeably different voice [[note]]provided by Karl Weidergott for the purpose of that joke; Flanders is regularly voiced by Creator/HarryShearer[[/note]] he says "Plus, you can replace them and no one can tell the diddly-ifference!"
** The episode "Simpsons Spin-Off Showcase" also spoofs this concept to hell and back. One of the spin-offs is "The Simpson Family Smile-Time Variety Hour", and episode host Troy [=McClure=] comments that one of the family refused to go along with the idea, but "...thanks to some creative casting, you won't even notice." When the episode starts up, we're greeted by the Simpsons... with a perky blond teenager ("Sophomore prom queen five years running", she calls herself) in place of Lisa.
** In the very early episodes of Season 1, Mr. Burns and Moe Szyslak were voiced by Christopher Collins (better known to most as Chris Latta, the voice of [[WesternAnimation/TheTransformers Starscream]] and [[WesternAnimation/GIJoeARealAmericanHero Cobra Commander]]) before Harry Shearer and Hank Azaria replaced him respectively. Hank Azaria[[note]]who replaced Collins [[TheOtherMarty before broadcast]][[/note]] would later go on to say that he was actually unaware that he had replaced another voice actor until Matt Groening told him; Groening himself said that his replacement was due to Collins being apparently extremely unpleasant to work with and frequently rude towards the other voice actors.
** In real life, all of Maggie Roswell's characters (Miss Hoover[[note]]Lisa's covert alcoholic teacher[[/note]], Maude Flanders, Helen Lovejoy, Luann Van Houten) were replaced for seasons 11-13 with Marcia Mitzman-Gaven while Roswell was out due to a pay dispute (she had moved to Denver and wasn't compensated for her travels between her home and Los Angeles), but the crew decided to just kill off Maude Flanders (because the writers and producers wanted to open up new storylines for Ned Flanders). Roswell returned after being allowed to record her lines from her home studio.
** Ralph Wiggum was also originally voiced by Jo Ann Harris for a few appearances before Nancy Cartwright took over the role from then on. Harris also initially voiced Wendell (the pale-white, sickly kid who always pukes), some of Bart's other friends (Richard and Lewis), and Lisa's friend Janey.
** Lunchlady Doris was retired as a character after Doris Grau died (she did appear in some episodes between the time her character was retired and the time Creator/TressMacNeille replaced her, but Doris was often seen in crowd scenes). Starting in Season 18, she returned a decade later with Tress [=MacNeille=] as her new voice actress.
** Troy [=McClure=] was almost always voiced by Phil Hartman, except in "Bart's Dog Gets an 'F'" where Dan Castellaneta (the voice of Homer and other characters) took over for a brief scene. After Hartman was murdered in 1998, both Lionel Hutz and Troy [=McClure=] were taken off the show (but still appear in some of the comics).
** Homer's mother was voiced by Creator/GlennClose starting with her proper introduction in "Mother Simpson", but in episodes before that and a few minor appearances, she's been voiced by both Maggie Roswell and Creator/TressMacNeille.
** Mobster Fat Tony is voiced by Creator/JoeMantegna in just about every appearance. With the exception of one line in "A Fish Called Selma" where he's voiced by Creator/PhilHartman. After that episode, Mantegna told the producers that he'd always make time to play Tony, no matter how small his part in the story was.
** Martin Prince and Sherri and Terri Mackleberry were voiced by Russi Taylor until her passing in Summer 2019. Starting with Season 31, Creator/GreyDeLisle has taken up these roles, and presumably the rest of Russi's regular roles on the show too.
** Krusty's daughter Sophie appeared as a one-off character in season 12 voiced by Creator/DrewBarrymore. 17 years and seasons later, Sophie reappeared and started making occasional appearances voiced by the presumably more available Creator/NatashaLyonne.
** After the documentary ''The Problem With Apu'' criticized the show's tendency to cast white actors as non-white characters, several [=PoC=] characters were recast with appropriate actors. Carl Carlson and Lou both went from Creator/HankAzaria to Alex Desert. Dr. Hibbert went from Creator/HarryShearer to Creator/KevinMichaelRichardson. His wife Bernice went from Creator/TressMacNeille to Creator/DawnnLewis. Bumblebee Man went from Hank Azaria to Eric Lopez. Julio (the campy gay guy) went from Hank Azaria to Tony Rodriguez. Kumiko (Comic Book Guy's Japanese wife) went from Tress [=MacNeille=] to Jenny Yokobori. Although Azaria supported these decisions, Shearer notably disagreed, saying "I have a very simple belief about acting. The job of the actor is to play someone who they are not.".
** In Latin America, after season 15, the ANDA acting union (which included most of the ''Simpsons'' voice cast) went on strike against the Grabaciones y Doblajes studio, which had acquired ''The Simpsons'' from the defunct Creator/Audiomaster3000 studio. The strike caused ANDA to lose the rights to 11 productions (including ''The Simpsons'', ''WesternAnimation/KingOfTheHill'', ''WesternAnimation/{{Futurama}}'', and ''Series/MalcolmInTheMiddle''), with many of the actors on strike getting banned from Grabaciones y Doblajes, which changed its name to New Art Dub. Only a few ''Simpsons'' actors survived the strike, notably Marina Huerta ([[TheOriginalDarrin the first voice]] of Bart, who left the series after season 9). The strike has been blamed for causing the show to go downhill in Latin America, [[GermansLoveDavidHasselhoff where the series is very popular]]. However, when the 32nd season began airing in Latin America in 2021, many of the departed cast members, including Creator/HumbertoVelez (the original Homer Simpson), [[TheOriginalDarrin came back]], thanks to the work of Alex Ortega, a FandomVIP within the Latin American ''Simpsons'' fandom. Also in the 32nd season, in addition to returning as Bart, Claudia Motta also took over the role of Marge Simpson.
** In the European Spanish version, Carlos Revilla, the voice of Homer and the show's dubbing director, passed away after recording Season 11. He was replaced in both capacities by Carlos Ysbert afterwords. Marge's voice (and by extention Patty and Selma's) has also changed twice in this dub, presumably because the actresses who played Marge (Amparo Soto in seasons 1 and 2, and Begoña Hernando from seasons 3 to 6) complained about their voices hurting while playing her. Her current voice actress, Margarita de Francia, took the role in Season 7 and has been voicing her ever since. In fact, most of the recurring characters in early seasons sound ''much'' more different than their later established voices (e.g. Apu, Lenny, Carl and Ned Flanders)
** Marge's German voice actress Elisabeth Volkmann died in the middle of season 17 (her final episode was "We're on the Road to D'oh-where"), and she's replaced by the Anke Engelke who doesn't try to imitate Volkmann's performance, but Julie Kavner's[[note]]Julie Kavner is Marge's voice actress in the American version. Kavner also voices the women in Marge's family, like her gruesome twin sisters Patty and Selma, her mother, Jackie, Great Aunt Gladys from "Selma's Choice", and some unnamed female relatives who had minor roles in other episodes[[/note]].
*** Also in the German version, Patty and Selma were voiced by two different women in season two, then Volkmann voiced them from season two until season 17.
*** Abraham Simpson has ''four'' different German voice actors. The first died after season 8, the second died after season 10, the third died after season 15.
*** Mr. Burns was voiced by Reinhard Brock, but after Brock's death, he was voiced by Creator/KaiTaschner.
*** Homer's German voice actor, Norbert Gastell, died in November 2015. He is now voiced by Christoph Jablonka.
*** A lot of German voice actors were replaced throughout the series. The only exceptions are the voice actors for the Simpsons kids, Ms. Hoover, Krusty the Clown, Moe, Dr. Marvin Monroe, and Manjula.
** Almost all characters in the Brazilian Portuguese cast had at least two or three voices.
** Only Homer, Marge, Bart and Lisa stayed more-or-less consistent in the Hungarian dub of seasons 1 to 29, though Lisa was recast for a batch of early episodes and Homer was replaced for a couple later eps due to the actor's scheduling conflicts. Everyone else changed their voices around far too often to keep track of; Flanders in particular has gone through probably about a dozen different actors. Homer's actor, József Székhelyi passed away before the 29th season was fully dubbed, and Bart's actor, Balázs Simonyi quit in response. János Háda took over as Homer and Tamás Markovics as Bart.
** The Italian dub had a lot of changes too: Ned Flanders had a different voice in the first two seasons, Moe's current voice is in only since Season 9, Season 22 had new voice actors for Marge, Bart and Grandpa and Homer's voice was changed in Season 24 after the original [=VA=]'s death.
** "[[Recap/TheSimpsonsS35E3McMansionAndWife McMansion and Wife]]" has Creator/HankAzaria voicing Jebediah Springfield instead of Creator/HarryShearer.
* ''WesternAnimation/SofiaTheFirst'' sees a few replacements:
** James has gone through three voice actors. He was voiced by Zach Callison of ''WesternAnimation/StevenUniverse'' fame in the pilot movie, all of season 1, and every season 2 episode up until "Sofia The Second". Tyler Merna voiced him from "Princesses To The Rescue" up until the "Elena Of The Secret Of Avalor" movie. Starting with "Camp Wilderwood" (which was produced after the latter movie, but aired before it), he's voiced by Nicolas Cantu.
** His friend Zandar has gone through four voice actors: Maxim Knight (pilot movie), Karan Brar (season 1), Cade Sutton (season 2), and Nathaniel Semson (season 3).
** In the pilot movie, Ruby was voiced by Fiona Bishop (who would go on to voice Princess Zooey, and sisters Meg & Peg). Starting in "The Big Sleepover", she's voiced by Diamond White.
** Ruby's mother Helen Hanshaw went from Viola Davis (The Buttercups) to Dawnn Lewis (Buttercup Amber).
** Prince Hugo went from Colin Ford (Just One of the Princes) to Grayson Hunter Goss (future appearances).
** Merida from ''WesternAnimation/{{Brave}}'' appears in "The Secret Library", but with the voice of Creator/RuthConnell instead of Creator/KellyMacdonald.
** Belle from ''WesternAnimation/BeautyAndTheBeast'' appears in "The Amulet and the Anthem" voiced by her current voice actress, Julie Nathanson, instead of Creator/PaigeOHara, who had retired from the role by that point.
** Creator/TraceyUllman voiced Lucinda's mother Marla in "Mom's the Word" before Laraine Newman took over starting with "Cauldronation Day".
** Nika Futterman voices Morgana in "Day of the Sorcerers" rather than Creator/CatherineOHara.
** Creator/MeganMullally voiced Miss Nettle for her appearances in seasons 1-3, before Anna Vocino voiced her in the season 4 episode "Ivy's True Colors".
* The ''Franchise/SonicTheHedgehog'' animated shows from Creator/DICEntertainment had a lot of these (only Jaleel White as Sonic remained on board in all three shows):
** In ''WesternAnimation/AdventuresOfSonicTheHedgehog'', Miles "Tails" Prower is voiced by Christoper Stephen Welch, while Dr. Robotnik was voiced by Long John Baldry. But in ''WesternAnimation/SonicTheHedgehogSatAM'', Tails is voiced by [[WesternAnimation/BeautyAndTheBeast Bradley]] [[Film/{{Jumanji}} Pierce]], while Dr. Robotnik is voiced by Creator/{{Jim Cummings|1952}}.[[note]]Ironically, Cummings voiced Dr. Robotnik in the pilot workprint for ''[=AoStH=]''[[/note]]
** In the ''[=AoStH=]'' special ''Sonic Christmas Blast'', Princess Sally from ''[=SatAM=]'' appears, but she has no lines (aside from gasps and moans) and is voiced by Creator/TabithaStGermain instead of Creator/KathSoucie. This is because of Soucie being under contractual obligations voicing Lola Bunny in ''Film/SpaceJam''. Also, Tails is voiced by Chris Turner instead of either Christopher Welch ''or'' Bradley Pierce.
** For ''[=SatAM=]'', Mark Ballou opted not reprise his role as Rotor for Season 2. He was replaced by Cam Brainard.
** ''WesternAnimation/SonicUnderground'' has Dr. Robotnik voiced by Garry Chalk (who, ironically, voiced Grounder in ''[=AoStH=]'').
* ''WesternAnimation/SouthPark'':
** Creator/MaryKayBergman, who did most of the female voices, committed suicide during production of the show's third season, not long after recording her dialogue and the ''Bigger, Longer & Uncut'' movie had been completed. Eliza Schneider (the same one who was one of many assistants for Beakman on the 1990s kids' science show ''Series/BeakmansWorld'') was hired to replace her, starting with the season 3 episodes Bergman hadn't yet recorded for, and she herself was later replaced by Creator/AprilStewart after season 7 (with Creator/MonaMarshall already handling some of the other roles, most notably Sheila Broflovski) when Schneider had to quit after running into salary troubles with her union.
** Some of the minor female classmates (that aren't Wendy or Bebe) have had their voices shift about by episode, depending on April Stewart's availability [[note]]such as her being ill during production on the episode "Marjorine" and having only recorded her lines for Wendy[[/note]] and the creators utilizing other actresses to cover other roles either due to that or to spread out the cast. In those cases, Creator/MonaMarshall, Jessica Makinson, and Paula Holmberg have covered for her.
** In fact, there is only one major female character that has not had any voice changes: Bebe Stevens, who has been voiced by Jennifer Howell from her first appearance [[note]]Though Howell was initially uncredited in "Weight Gain 4000", leading some fans to mistakenly assume that Bergman was Bebe's voice actress there, a misconception that sometimes persists[[/note]].
** Tolkien was initially voiced by Trey Parker in minor speaking lines given to him in season 3, but Adrien Beard became his official voice actor when he received more prominent speaking parts (starting with season 4).
** The youngest of the Goth kids was initially voiced by Nico Agnone. After Agnone hit puberty, the role was given to Sebastian Yu.
** Clyde's mother was initially voiced by April Stewart, but would wind up voiced by [[CrossDressingVoices Trey Parker]] in "Reverse Cowgirl" when Stewart was unavailable to re-record lines.
** Ike Broflovski has gone through at least nine confirmed voice actor changes[[note]]though this is justified, as Ike is voiced by an actual child, usually a production staff member's kid[[/note]]. This is usually averted in most foreign dubs, where he's instead voiced by adult women. On the episode "Taming Strange",[[note]]the episode that parodied Music/MileyCyrus shedding her kiddie entertainment image for a HotterAndSexier one and the technical complications behind the Obamacare website[[/note]] Ike (when he went through puberty) was voiced by Matt Stone.
** Terrance is usually voiced by Matt Stone, while Phillip is voiced by Trey Parker. But in their very first appearance (in "Death"), the voice casting was reversed, with Stone as Phillip and Parker as Terrance.
** Scott Tenorman was originally voiced by Toby Morton, but was later voiced by Trey Parker in the infamous "200"/"201" two-parter.
** The leader of the 6th graders was voiced by Rochelle Leffler in his sporadic appearances in the show. Due to Leffler not being available for ''[[VideoGame/SouthParkTheStickOfTruth The Stick of Truth]]'' video game, Trey Parker took over the role.
** The Spanish-language Latin American dubs have had many cases of recasting, but it would take too long to list all of them. To sum up the situation, the show has been passed around to various studios and localization teams, with an overhaul in the voice cast coming every few seasons or so. Some of the earlier dubbed episodes have even been redubbed for consistency with the current voice cast, making it even more of a challenge (though [[http://doblaje.wikia.com/wiki/South_Park this Spanish wiki]] attempts to catalogue the numerous changes). A few notable examples include:
*** Stan was voiced by Larry Villanueva in the original BVI dub (and later redub) of seasons 1-2. After Villanueva took a hiatus from voice acting to work in film, he was replaced by Miguel Paneke in seasons 3-7, and Sergio Saez in seasons 8-9. He would return for seasons 10-15, but retired from the show due to being busy and not wanting to commute to the new ADR studio. Orlando Noguera (best known for voicing [[WesternAnimation/{{Animaniacs}} The]] [[WesternAnimation/PinkyAndTheBrain Brain]]) was then cast as Stan for the following season.
*** [[ActingForTwo Kyle AND Cartman]] were both initially voiced by Vivian Ruiz, but she quit after BVI's second season because Cartman's voice was murder on her vocal cords. She was replaced by Patricia Azan for the rest of the series.
*** Kenny was initially left undubbed through the Latin American adaptations of seasons 1-11 (due to Kenny normally having his voice muffled and not having any true speaking lines until the ''Bigger, Longer & Uncut'' movie), but the actor Orlando Noguera was cast as his official voice starting in 12. This was a somewhat controversial decision, as Noguera did not muffle his voice, allowing viewers to hear the dialogue, which can sometimes be vulgar. The role was then recast in the sixteenth season, as Noguera took on two other roles (Stan and Butters). He was replaced by Diego Osorio until the end of the run, as Osorio moved to Los Angeles. Fabian Hernandez took on the Kenny role for season 17, although Orlando Noguera reprised the role in episodes 7-10, and season 18 and later.
** A short-lived dub that aired in Mexico around 1998 (simultaneously with BVI's first dub) had Stan first voiced by Creator/CarlosInigo, before he was replaced by Creator/EduardoGarza for the second season. There were also two competing dubs of the movie that were produced in Mexico. While the first retained the cast from the aforementioned adaptation of the series, a dub for pay TV recast several parts, most notably Kenny and Wendy (who respectively went from being voiced by Creator/IrwinDaayan and Creator/MariaFernandaMorales, to Creator/VictorUgarte and Claudia Aline).
** In the case of the Japanese dubbing situation for the series, the satellite station WOWOW had a dub that aired through from 1999 to 2004, before they lost the broadcasting rights. In this version, Cartman was [[CrossDressingVoices voiced by a Japanese-Swedish actress known as LiLiCo]], while the other three boys were cast with male actors, with Creator/KappeiYamaguchi voicing Kyle and Stan voiced by Creator/HiroYuki. While the WOWOW dub had started production, the movie (released in 2000) wound up handled by a different localization team, who presented a reverse casting situation: Stan, Kyle, and Kenny were voiced by women (respectively Yuki Ueda, Kaoru Kusumi, and Junko Katayama), while Cartman was voiced by a man (Tetsuya Yanagihara). These actors were more obscure, and the rest of the cast of the film dub is unknown due to the lack of credits. After FOX [=BS238=] briefly picked up the broadcasting rights in October 2011, they produced a dub of season 8 which recast all the characters.
*** The WOWOW version first had Chef voiced by the actor Nobuaki Kondo (under the alias BRO-Kone) for seasons 1-5, but by Masahiro Kobayashi for the last two seasons.
*** Ike was initially voiced by a child actor named Hiroshi Tanaka for the first three seasons, but was replaced by another actor (Takashi Hirano) for seasons 4-7.
*** Jesus was first voiced by the actor Masaya Nakagawa (under the alias "Lily Franky") for seasons 1 and 2, but was replaced by Masayuki Nakata in season 3.
*** In the switchover from WOWOW to FOX, most of the female roles went from being voiced by Noriko Suzuki to Hana Takeda. The exception was Wendy Testaburger, who was now voiced by Ema Kogure.
*** Pip was usually voiced by Creator/MitsuruOgata[[note]]who also voiced Kenny and other roles[[/note]] in WOWOW's dub, except for the dub of "Cartman Gets An Anal Probe", where Noriko Suzuki voiced him instead [[note]]she voiced Wendy and most other female characters in the dub, along with a few male roles such as Kevin Stoley, Dog Poo, and Kenny's brother named Kevin[[/note]]. In a reverse of that situation, while Butters was best known for being voiced by Noriko Suzuki in that dub, his early lines in season 2[[note]]while he was still a background character with a different voice, and may or may not have still been voiced by Matt Stone[[/note]] were voiced by Mitsuru Ogata.
** The dub produced in Spain used an entirely different cast between the movie and TV series, due to the movie being handled by Tecnison and the series being handled by SDI Media. While the boys are [[CrossdressingVoices voiced by women]] in the TV series, here they all have male voice actors: Stan (Chelo Vivares/Miguel Angel Varela), Kyle (Sara Vivas/Pablo Sevilla), Kenny (Sara Vivas again/Adolfo Moreno), and Cartman (Margarita Ponce/Eduardo del Hoyo). However, the movie's cast would leech into the TV series: Hector Cantolla (Satan in the movie) would reprise that character in Season 4; Ponce ''does'' appear in the movie dub, but as Stan's mother; Varela did a few additional voices throughout the series; Moreno later voiced Scott Tenorman; and Roberto Encinas (Big Gay Al) is currently voicing PC Principal.
*** Bebe was originally voiced by Isacha Mengibar (who also voices Wendy, Shelly and Ike), and her role has juggled between a lot of voice actress before being assigned to Celia de Diego. Similarly, Craig and Jimmy were originally voiced by Chelo Molina (who also voices Clyde in this dub), but starting from Season 21 they are voiced by Yolanda Mateos and Inma Gallego respectively.
** The Brazilian dub had its movie and series handled by different localization teams (Cinevideo in Rio for the film, The Kitchen Inc. and BVI in Miami for series [[note]]Both companies were also responsible for the later Latin American Spanish dubs of the series[[/note]]). As with the film dub in Spain, the boys (save for Kenny) had male actors voicing them, while the series had them voiced by women (save for Kenny). As with the Latin American dub and the Ukrainian dub, Kyle and Cartman coincidentally share the same voice actress (Marta Rhaulin at first, Carla Cardoso later when Rhaulin moved onto another dubbing studio).
** The Italian dub switched cities after season 4 from Rome to Turin. As such, the entire cast was replaced and the original seasons were redubbed.
* ''Film/SpaceJamANewLegacy'' featured WesternAnimation/LolaBunny voiced by Creator/{{Zendaya}} instead of Creator/KathSoucie, who played her in the [[WesternAnimation/SpaceJam original film]].
* In ''WesternAnimation/TheSpectacularSpiderMan'', Tombstone was originally voiced by Creator/KeithDavid in his first appearance, but due to him being involved in other projects, Creator/KevinMichaelRichardson took over the role, doing an extremely convincing imitation of David.
* ''WesternAnimation/SpiderManTheAnimatedSeries'' had a few voice changes over its run:
** The Scorpion was originally voiced by Martin Landau for the first two seasons. After he won an Oscar for ''Film/EdWood'', Landau was unavailable to continue voicing the character and the role then went to Creator/RichardMoll (probably best known to animation fans as the voice of Two-Face in ''WesternAnimation/BatmanTheAnimatedSeries'' and sitcom fans as Bulls in ''Series/NightCourt'').
** Aunt May was voiced by Linda Gary for much of the series's run (reprising her role from an earlier adaptation). After her death, Julie Bennett provided her voice for the rest of the show.
** Similarly, Nick Fury's actor Philip Abbott (who also voiced the character in ''WesternAnimation/IronManTheAnimatedSeries'') was replaced by Jack Angel after his death.
** Whistler went from Creator/MalcolmMcDowell to Oliver Muirhead (who'd voice the Spot earlier).
** Barring Creator/QuintonFlynn as the Human Torch, the Fantastic Four had different voice actors from the ones they had in [[WesternAnimation/FantasticFourTheAnimatedSeries their show]]. Doctor Doom and Daredevil also had different voices.
** While this trope within the series itself, during the "Secret War" arc, Storm is TheOriginalDarrin as she went from her second ''WesternAnimation/XMenTheAnimatedSeries'' voice actress Alison Sealy-Smith (who voiced the character during the X-Men's guest appearance) to her original voice actress, Iona Morris.
** The episode "The Cat" had the Red Skull appear in flashback and voiced by Creator/DavidWarner (though he was only credited for voicing Herbert Landen in the episode). When the Red Skull returned in the "Six Forgotten Warriors" five-parter and the "Secret Wars" three-parter, he was instead voiced by Earl Boen.
* ''WesternAnimation/SpongeBobSquarePants'':
** The Dirty Bubble was voiced by the late Creator/CharlesNelsonReilly in the first episode that he appeared in, "Mermaid Man and Barnacle Boy II", but was replaced by Creator/TomKenny in "Mermaid Man and Barnacle Boy V" and in his later appearances. However, Reilly [[TheOriginalDarrin returned]] to voice him in ''[[VideoGame/SpongeBobSquarePantsLightsCameraPants Lights, Camera, Pants!]]''.
** Man Ray was voiced by John Rhys-Davies in his first two appearances in "Mermaid Man and Barnacle Boy III" and "Mermaid Man and Barnacle Boy V". His subsequent appearances have been voiced by Bob Joles.
** In Germany:
*** Patrick was voiced by Marco Kroeger from Seasons 1-7, until he was fired over a salary dispute and Fritz Rott voiced Patrick in Seasons 8 and 9 and the second movie.
*** Squidward went through three German voice actors. For the main series, from the pilot right up to the mid-season finale of Season 9, he was voiced by Eberhard Prüter. After Prüter died before the release of the second trailer for ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'' he was voiced by Rüdiger Evers as a last-minute temporary replacement. For ''Sponge Out of Water'' he was voiced by Tobias Lelle. The rest of the series has him voiced by Joachim Kaps, who sounds like none of them.
*** Barnacle Boy's German voice was Uwe Paulsen, but after health complications forced Paulsen to leave the show, Hasso Zorn subsequently voiced him.
*** Plankton's original German voice, Thomas Petruo, died in April 2018. He was replaced by Sebastian Cristoph Jacob after "Shopping List".
** Squidward's European Spanish voice actor (and the dub's director), Alberto Closas Jr., was replaced by Miguel Campos for a handful of episodes in seasons 5 and 6 due to a studio switch, although he did eventually [[TheOriginalDarrin reprise the role]]. Actress Silvia Gambino, who voiced Pearl and Mrs. Puff, was replaced after season 3 due to her leaving the show.
** In the French dub: Creator/MicheleLituac, who voiced most of the main female characters, moved to Canada after season 2 and was replaced by Hélène Chanson. Henri Courseaux, who voiced Squidward, retired from voice acting during season 7, with Michel Mella taking over. Érik Colin, who voiced Patrick, died in 2013; he was replaced by Creator/BorisRehlinger in time for ''Sponge Out of Water''.
** Mr. Krabs' mother was voiced by Paul Tibbitt in her first two appearances and by Sirena Irwin in all subsequent appearances.
** Patchy the Pirate's parrot Potty was originally voiced by series creator Stephen Hillenburg. By the fourth season, Paul Tibbitt replaced Stephen Hillenburg because he didn't want to voice the character anymore. As of the episode "Feral Friends", Potty is voiced by Mr. Lawrence, presumably because of Paul Tibbitt resigning as showrunner to focus on ''WesternAnimation/TheSpongeBobMovieSpongeOnTheRun''.
** In the Ukrainian QTV dub, Dmitry Tvarkovsky replaced Alexander Chmyhalov as [=SpongeBob=] after he died. In the Ukrainian 1+1 dub, Yevhen Loktionov replaced Pavlo Skorohodko from "Gullible Pants" to "Kracked Krabs" and ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'', due to Pavlo being ill.
** The Latin American Spanish dub has gone through a dozen different voice actors for the majority of the characters for various reasons (then again, it's recorded at Creator/EtceteraGroup) - ranging from voice actors retiring to voice actors moving away (mostly due to the political situation in Venezuela, where the dub is made) to pay disputes. Some of the bigger examples include:
*** The dub went through major cast changes after the first season. Many voice actors, including Creator/KaihiamalMartinez ([=SpongeBob=] himself) were fired from Etcétera or just the show after attempting to strike the studio over salary disputes. Besides Martínez (who was replaced by the long-running Creator/LuisCarreno), other changes due to these reasons included Óscar Zuloaga[[note]]who lasted a bit longer[[/note]] (Plankton) to Creator/LuisMiguelPerez, Mercedes Prato (Sandy) to Anabella Silva, and Antonio Delli (Barnacle Boy and Larry the Lobster) to José Méndez and Luis Miguel Pérez respectively. Others moved away from Venezuela; these changes include Rocío Mallo (Karen) to Melanie Henríquez, Irina Índigo (Pearl) to Yensi Rivero, and Orlando Noguera (French Narrator and sign reader) to Juan Guzmán.[[note]]All three moved to Mexico, with Mallo eventually returning to Venezuela and Noguera settling in Miami.[[/note]]
*** Paul Gillman, Patrick's original voice, retired from dubbing in 2004 to reinvigorate his well-known musical career. Alfonso Soto took over from [[WesternAnimation/TheSpongeBobSquarePantsMovie the first movie]] and fourth season onwards.
*** Anabella Silva, Sandy's best-known voice, was briefly replaced by Yaraiví Alcedo for a number of episodes before Silva returned to the role. After Silva retired from dubbing after moving to London in 2008, Lileana Chacón took over as Sandy and has voiced her since then.
*** Luis Pérez Pons, Mr. Krabs' original voice, left Etcétera and was replaced by Carlos Vitale in that same year. However, after Vitale retired in 2015, Pérez Pons returned to the studio and, upon reaching an agreement, [[TheOriginalDarrin reprised his role as Mr. Krabs]] for the remainder of the series up until his death on October 24, 2023. He was replaced by Mexican voice actor Olin Garcés, recording in separate recording sessions at Etcétera's partner studio DAT.
*** Luis Miguel Pérez, who voiced Plankton, semi-retired after moving from Caracas to Mérida; he was succeeded by Ángel Mujica.
*** This was narrowly averted with the current [=SpongeBob=] himself; Luis Carreño kept his role after having moved to Miami by recording his dialogue for the character in separate recording sessions at Etcétera's office there. A similar thing happened with the current voice actors for Pearl and Karen, Mariangny Álvarez and Sixnalie Villalba, who continued voicing their characters after moving to Chile via recording from home studios.
*** To date, Renzo Jiménez (Squidward), Armando Volcanes (Flying Dutchman, Mermaid Man, and Barnacle Boy), and Juan Guzmán (Patchy the Pirate) are the only cast members in the dub's history who have yet to be replaced.
** The Brazilian dub eventually changed Patrick and Mr. Krabs, while Squidward had to get a replacement after his original dubber died.
* ''WesternAnimation/{{Squidbillies}}'':
** Charles Napier was the voice of the Sheriff in the first nine episodes of the show, being replaced by Bobby Ellerbee. At the end of the ninth episode, one of Sheriff's clones (voiced by Ellerbee) comes up to Sheriff (voiced by Napier) and beats him to death.
** Music/UnknownHinson, the original voice of Early Cuyler, was fired for his comments towards Black Lives Matter and Music/DollyParton in August 2020, and was replaced by Creator/TracyMorgan in the 13th and last season of the show.
* ''WesternAnimation/StarWarsTheCloneWars'':
** Jar Jar Binks was voiced in the launch movie and "Bombad Jedi" by his original film performer Ahmed Best (one of the few film actors to reprise their role), but was replaced for all subsequent episodes in Season 1 by Creator/PhilLaMarr under the pseudonym "BJ Hughes" (which Best [[https://twitter.com/ahmedbest/status/1222616635497803776 stated]] was due to the role being "very painful" to him at the time). Ahmed Best returned for the Season 3 episode, "Supply Lines" and all subsequent appearances.
** In both Canadian French and Latin American Spanish, the entire voice cast was replaced by their European counterpart cast for Season 6.
** In Hungary, Tamara Zsigmond (who voiced Padme in the films) ''only'' voiced her in the first season. For the remainder of the series, Kata Csondor took over. Season 6, dubbed much later than the rest of the series, also recast multiple recurring characters, either due to scheduling conflicts or budget issues (Obi-Wan, Count Dooku) or deaths (Yoda, Jar Jar Binks). Palpatine's voice actor was replaced too during season 2 for the latter reason. Many smaller roles were also recast during the series, such as Plo Koon or Cad Bane. In ''WesternAnimation/StarWarsRebels'', Darth Sidious was recast, as well as Hondo after his initial appearance and Minister Tua for her final episode. C-3PO will be given a new voice for any future appearances, due to the death of his usual voice actor.
* ''WesternAnimation/StevenUniverse'':
** Starting with the episode "[[Recap/StevenUniverseS2E20SadiesSong Sadie's Song]]", David "Sinbad" Adkins was replaced by Colton Dunn as the voice of Mr. Smiley.
** Bismuth's usual voice actress, Uzo Aduba, was replaced by Miriam Hyman for ''VideoGame/UnleashTheLight'' and the last three episodes of ''WesternAnimation/StevenUniverseFuture''. The reason for this is unknown, considering Aduba still voiced Bismuth in an earlier ''Future'' episode, "[[Recap/StevenUniverseFutureS1E12BismuthCasual Bismuth Casual]]".
* In ''WesternAnimation/{{Stripperella}}'', for his first appearance the villain Cheapo was voiced by Creator/JonLovitz (from ''Series/SaturdayNightLive'' and the short-lived animated series ''WesternAnimation/TheCritic''); for the remainder of his appearances, he was voiced by Creator/MauriceLaMarche.
* ''WesternAnimation/{{Superfriends}}''. By the time the show reached ''The Super Powers Team'' version, Superman, Robin, Green Lantern, Samurai, Mr. Mxzyptlk and Lex Luthor were the only returning characters to retain their original voice actors.
** Batman was originally voiced by Olan Soule, but the final two iterations ''Super Friends: The Legendary Super Powers Show'' and ''The Super Powers Team: Galactic Guardians'' replaced Soale with Creator/AdamWest, reprising his role as the Caped Crusader from [[Series/Batman1966 the 1960's live-action TV show]].
** Aquaman was initially voiced by Normal Alden, with Bill Callaway replacing Alden by the ''New Super Friends''[=/=]''Challenge of the Superfriends'' era.
** Shannon Farnon voiced Wonder Woman for most of the cartoon's run, but was replaced by Connie Cawlfield in ''The Legendary Super Powers Show'' and by Creator/BJWard in ''Super Powers Team''.
** Jayna of the Wonder Twins was originally voiced by Louise Williams before being recast with BJ Ward in ''The Legendary Super Powers Show''.
** The Flash was originally voiced by Creator/TedKnight, then by Barney Phillips in ''The All-New Super Friends Hour'' and by Creator/JackAngel for ''Challenge of the Superfriends'' onward.
** Sinestro was voiced for his first two speaking roles in ''Challenge of the Superfriends'' by Vic Perrin, by Creator/DonMessick for the remainder of his ''Challenge'' speaking roles and by Jeff Winkless in the lost season episode "Revenge of Doom".
** Creator/TedCassidy voiced Brainiac for his appearances on ''Challenge of the Superfriends'' but was replaced by Stanley Ralph Ross for the rest of Brainiac's speaking appearances due to passing away a short time after ''Challenge'' ended its run.
** The Scarecrow was voiced by Don Messick on ''Challenge of the Superfriends'' and by Andre Stojka for his final appearance in the ''Super Powers Team'' episode "The Fear".
** Black Manta was voiced by Ted Knight during his appearance on ''The All-New Super Friends Hour'' where he was renamed The Manta, with Ted Cassidy voicing him for his appearances on ''Challenge of the Superfriends''.
** Bill Callaway voiced Bizarro for all but one of his appearances, with the ''Super Powers Team'' episode "The Bizarro Super Powers Team" instead having him voiced by Superman's voice actor Danny Dark.
** Dr. Martin Stein was originally voiced by Olan Soule in ''Super Friends: The Legendary Super Powers Show'', with Ken Sansom replacing Soule for the final series ''The Super Powers Team: Galactic Guardians''.
* ''WesternAnimation/TheSuperheroSquadShow'':
** Creator/JaneLynch (Sue Sylvester from ''Series/{{Glee}}'') voiced ComicBook/{{Thanos}}' sister Nebula, but when she became unavailable to record more episodes, the creators found an interesting way to work around this. In each of Nebula's subsequent appearances, she was either [[BoundAndGagged gagged]] or had her [[WipeThatSmileOffYourFace mouth removed entirely]], allowing an uncredited actress to easily replace Lynch simply by doing muffled "Mmmph" noises.
** Thanos himself went through this, as a Skrull who impersonated him was voiced by Creator/SteveBlum, but when the real Thanos appears, he was voiced Creator/{{Jim Cummings|1952}}.
* ''WesternAnimation/{{Superjail}}'' has had a few examples with minor characters:
** Jared's DistaffCounterpart Charise was originally voiced by Kamala Sankaram in "Ladies' Night". In subsequent appearances, she's been voiced by Sally Donovan.
** Some of the Ultraprison inmates were voiced by Kamala Sankaram in the above episode, with Sally Donovan voicing others. All Ultraprison inmates were voiced by Donovan in "Stingstress".
** Bruce was voiced by a woman named Melissa Brown when he originally appeared, but was later voiced by Chris [=McCulloch=] starting with "Stingstress", as Brown had either retired or was otherwise unavailable.
** The Time-Police were also recast for their cameo in season 3, with one of them (the lead singer) originally having been voiced by Reggie Watts while his main partner was voiced by [=McCulloch=]. In the "Oedipus Mess" cameo, [=McCulloch=] voices one patroller while Stephen Warbrick appears to have voiced the other. The designs are identical to the original Time Police characters, but given the show's love for re-using designs and stock footage, they may have also been intended to be different ones.
* Between ''Series/TheSuperMarioBrosSuperShow'' and ''WesternAnimation/TheAdventuresOfSuperMarioBros3'', three-fifths of the main cast got switched out for new ones for unknown reasons, which they kept up through ''WesternAnimation/SuperMarioWorld''. Mario, originally voiced by Wrestling/CaptainLouAlbano, is now voiced by Walker Boone; Luigi, who was originally Danny Wells, is now voiced by Tony Rosato[[note]](a former cast member of Canada's sketch show ''Series/{{SCTV}}'' and the [[LongRunners long-running]] American sketch show ''Series/SaturdayNightLive'')[[/note]]; and Princess Toadstool, originally Jeannie Elias[[note]]who would later be the voice of Creepy Susie on ''WesternAnimation/TheOblongs''[[/note]], is now voiced by Tracey Moore. Averted by Toad and King Koopa, who retained John Stocker and Harvey Atkin as their respective voice actors on both shows (with Stocker later voicing Oogtar on ''World'' in Toad's absence).
* ''WesternAnimation/SuperRobotMonkeyTeamHyperforceGo'': The Latin American Spanish dub switched dubbing countries, moving from Chile (for the first two seasons) to Argentina (for the final two seasons), thus requiring a complete change for the entire cast.
* ''WesternAnimation/TheSwanPrincess'':
** Most of the cast changed between the first movie and the second movie, except Michelle Nicastro (who spoke as Odette in the first film, and sang in the sequels) and Steve Vinovich (Puffin). In the latest movie ("The Swan Princess Christmas"), Odette and Puffin got new voice actors.
** The Latin American Spanish and French dubs completely changed countries, moving from Los Angeles (for the first movie) and Mexico (for the first two sequels) to Argentina, and France to Belgium.
* ''WesternAnimation/SymBionicTitan'': In her first appearance, Kimmy is voiced by Cassie Scerbo. For the rest of the show, she is voiced by Creator/KariWahlgren.
[[/folder]]

[[folder:T-Z]]
* ''WesternAnimation/{{Tak and the Power of Juju|2007}}'' recasts several characters, with Lok and Dead Juju/Party Juju being the only characters originating from [[VideoGame/TakAndThePowerOfJuju the video game series]] to retain their original voice actors.
** Creator/JasonMarsden is replaced as the voice of Tak by Creator/HalSparks.
** Lloyd Sherr replaces Creator/JohnKassir as the voice of Jibolba.
** Tlaloc, [[AdaptationNameChange renamed "Traloc"]], is voiced by Creator/JeffBennett rather than Creator/RobPaulsen.
** Mind Reader Juju, here called "Psychic Juju", is voiced by S. Scott Bullock instead of Rob Paulsen.
** Creator/MauriceLaMarche replaces Jeff Bennett as Belly Juju and Creator/LaraJillMiller as Dinky Juju.
** Darkness Juju, the cartoon's interpretation of Travis the Dark Juju from ''VideoGame/TakTheGreatJujuChallenge'', is voiced by Mitch Watson instead of Creator/DeeBradleyBaker.
* ''WesternAnimation/TangledTheSeries'', which is based on ''WesternAnimation/{{Tangled}}'' sees a few replacements:
** Creator/JulieBowen replaces Creator/KariWahlgren as Rapunzel's mother though the latter only had one line in ''WesternAnimation/TangledEverAfter''.
** Creator/DeeBradleyBaker replaces Creator/FrankWelker as both Pascal and Maximus.
** In the film, child Rapunzel was voiced by Delaney Rose Stein. The episode "Pascal's Story" has her voiced by Ivy George.
* ''WesternAnimation/TeamUmizoomi'' has Milli and Door Mouse. Milli's current voice actor is Madeline Rose Yen (previously voiced by Sophia Fox). Door Mouse was voiced by Joe Narcisco before Chris Phillips took the role. The voice change was obvious in Door Mouse, but very seldom in Milli.
* ''WesternAnimation/TeenageMutantNinjaTurtles1987'' had several cases:
** Raphael was voiced by Creator/RobPaulsen for the majority of the series, but for two season three episodes he was handled by Thom Pinto, in the "Europe Vacation" season he was voiced by Hal Rayle, and in the tenth and final season he was voiced by Michael Gough.
** Whenever Barry Gordon was unavailable during some third season episodes as well as a few in the "Europe Vacation", his characters of Donatello and Bebop were instead voiced by Greg Berg.
** Shredder was voiced by James Avery most of the time, but for a couple episodes of the third season he was voiced by Dorian Harewood, in most of the "Europe Vacation" season he was voiced by Creator/{{Jim Cummings|1952}}, after Avery left the series in the middle of season seven, Townsend Coleman provided his voice for the rest of it, and for seasons eight-ten (the "Red Sky" ones) he was voiced by William E. Martin.
** Vernon was voiced by Creator/PatFraley in the first season and spent it as a fellow reporter who was willing to help April out. Beginning with the second season and for the remainder of his appearances, he was voiced by Peter Renaday and [[CharacterizationMarchesOn became April's cowardly rival who always tried to one-up her and sucked up to his boss]].
** April and Vernon's boss Burne Thompson and Krang were voiced by Fraley for the majority of the series, but whenever he was unavailable they were instead handled by Townsend Coleman.
** When the 1987 characters were featured in the ''WesternAnimation/TurtlesForever'' crossover, union issues forced 4Kids Entertainment (producers of [[WesternAnimation/TeenageMutantNinjaTurtles2003 the 2003 Turtles cartoon]]) to use their in-house New York actors, rather than the original cast.
** The Brazilian dub changed a few of the main actors, namely Krang, Michelangelo (to Krang's second voice actor), Raphael, Splinter, and Shredder.
** The French dub started at the SOFI studio. Creator/VincentRopion (Raphael's first voice actor) was replaced after the first two seasons, and Loïc Baugin (Leonardo's first voice actor) after Episode 30. Beginning with Episode 107, the dub moved to H2 Productions and replaced the entire voice cast. Beginning with Episode 138, the dub moved to the Prodac studio, re-casting everyone [[TheOriginalDarrin while bringing back]] Mark Lesser (Leonardo's second voice) and Creator/LaurenceCrouzet (April's first voice).
* ''WesternAnimation/TeenageMutantNinjaTurtles2012'':
** Leonardo was initially played by Jason Biggs, [[RoleEndingMisdemeanor/WesternAnimation but was fired partway into the second season]] due to Biggs' conduct on social media. He was replaced by Dominic Catrambone for the remainder of the second season, then replaced by Creator/SethGreen for the remainder of the run. As Green sounds noticeably different from Biggs, this was mentioned in-universe as being due to Leonardo's vocal chords being damaged.
** The crossovers with the 1987 cartoon, unlike ''Turtles Forever'', was actually able to have the same actors from the original cartoon reprise their roles, but had Creator/KevinMichaelRichardson become the new voice for 1987 Shredder because of James Avery's passing.
** The Brazilian dub changed both Raphael after dubber Hermes Baroli moved to the United States (he hasn't retired from the medium yet, recording voiceovers in both local and home studios) and Leonardo following the death of dubber Antonio Akira. April also had another voice for half of Season 3 to cover her dubber's maternity leave.
* ''WesternAnimation/{{Teen Titans|2003}}'':
** Creator/KeithSzarabajka was the initial voice of Trigon before Creator/KevinMichaelRichardson took over the role when he was upgraded to the main villain for season 4. The creators explained the change by stating that the first Trigon was only meant to be Raven's mental manifestation of him, so they could easily recast the character.
** While Lauren Tom voiced Jinx and Gizmo in most of their appearances in the show, Tara Strong filled in for both characters when it came to the episodes "Revved Up" and "Titans Together" in the final season, though [[TheOriginalDarrin Tom would later return to voice the characters in]] ''[[TheOriginalDarrin Teen Titans Go!]]''.
** Marc Worden replaced Thomas Haden Church for Killer Moth after the character's first episode, though his auto-processed voice made it hard to tell the difference.
** In the Hungarian dub of [[WesternAnimation/TeenTitansTroubleInTokyo the movie]], all of the Teen Titans are replaced with different voice actors.
* For the spin-off series ''WesternAnimation/TeenTitansGo'':
** Creator/ScottMenville (Robin) replaces Thomas Hayden Church and Marc Worden as Killer Moth, the late Glenn Shadix as the Brain, Creator/JasonMarsden as Billy Numerous, and Mike Erwin as Speedy. Menville also briefly took over Creator/RodgerBumpass as Doctor Light for an episode before the latter [[TheOriginalDarrin reprised his role]] as the character in later episodes.
** Creator/WillFriedle replaced Creator/MichaelRosenbaum as Kid Flash.
** Creator/FredTatasciore replaces the late Creator/RobertMorse as [[BadSanta Santa Claus]] in his future appearances following Morse's death in 2022.
** In the Italian dub, Creator/GabrielePatriarca and Creator/MinoCaprio replace respectively Creator/LeonardoGraziano and Roberto Draghetti as Beast Boy and Cyborg. In Season 3, Mino Caprio is replaced again by Luigi Ferraro.
* In ''WesternAnimation/TheTick'', Arthur was voiced by [[Franchise/TheMonkees Micky Dolenz]] in the first season, then Creator/RobPaulsen took over for the rest of the series.
* ''WesternAnimation/ThomasAndFriends'' changed its entire Japanese dub cast after the eighth season when the show [[ChannelHop switched stations]] from Fuji TV to [=NHK=] and talent agencies from Aoni Production to 81 Produce.
** In the UK, Ringo Starr was replaced by Michael Angelis as storyteller for the third series, up until its sixteenth series.
* ''WesternAnimation/TinyToonAdventures'':
** After Creator/CharlieAdler left in the middle of Season 3 after being rejected for a role in ''Animaniacs'', John Kassir took over as Buster Bunny.
** Also, Creator/RobPaulsen voiced Furrball in "Duck Trek" instead of Creator/FrankWelker.
** After the passing of Creator/DonMessick in 1997, Creator/BillyWest provided the voice of Hamton in subsequent TV promos and video games.
* ''WesternAnimation/ToadPatrol'': Nancy Neilson took over Elf Cup from Dawn Ford in Season 2, while Dawn stuck around as Shaggy Mane.
* ''WesternAnimation/TopCat'' had several voice actor changes:
** The main character was first voiced by Arnold Stang. Stang did not return in ''Yogi's Ark Lark'' and Daws Butler took over the role. His next appearance in ''Yogi's Treasure Hunt'' had Stang return to the role and voiced the character two more times in ''Top Cat and the Beverly Hills Cats'' and ''Fender Bender 500''. Arte Johnson voiced the character in ''Yo Yogi!''. Jeff Bergman voiced the character very briefly in a ''Web Premiere Toons'' short until Tom Kenny took over. Kenny voiced the character in ''Harvey Birdman: Attorney at Law'' and some miscellaneous stuff (like commercials).  Jason Harris Katz voiced the character in the english dubs of ''Top Cat: The Movie'' and ''Top Cat Begins''. Thomas Lennon now voices the character in ''Jellystone!''.
** Benny was voiced by Maurice Gosfield in the original series. Gosfield passed away 2 years after the show ended, so because of this, in ''Yogi's Ark Lark'', John Stephenson took over the role. In ''Top Cat and the Beverly Hills Cats'', Avery Schreiber voiced the character. Creator/MauriceLaMarche voiced the character in ''Harvey Birdman Attorney at Law'' and Chris Edgerly voiced the character in the english dubs of ''Top Cat: The Movie'' and ''Top Cat Begins''. Finally, in ''Jellystone!'', the character was voiced by CH Greenblatt.
** Choo Choo was voiced by Marvin Kaplan in the original series. Kaplan voiced the character two more times in ''Top Cat and the Beverly Hills Cats'' and ''Fender Bender 500''. Tom Kenny then voiced the character in ''Harvey Birdman Attorney at Law''. Jason Harris Katz voiced the character in the english dubs of ''Top Cat: The Movie'' and ''Top Cat Begins''. In ''Jellystone!'', the character is now voiced by Jenny Lorenzo.
** Brain was voiced by Leo De Lyon in the original series and ''Top Cat and the Beverly Hills Cats''. In the english dub of ''Top Cat: The Movie'' and ''Top Cat Begins'', Jason Harris Katz voiced the character. Finally, in ''Jellystone!'', the character was voiced by Georgie Kidder.
** Fancy Fancy was voiced by John Stephenson in the original series and ''Top Cat and the Beverly Hills Cats''. Chris Edgerly voiced the character in ''Harvey Birdman Attorney at Law''. In the english dubs of ''Top Cat: The Movie'' and ''Top Cat Begins'', the character was voiced by Matthew Piazzi. Finally, in ''Jellystone!'', the character was voiced by Andrew Frankel.
** Spook was voiced by Leo De Lyon in the original series and ''Top Cat and the Beverly Hills Cats. Ben Diskin then voiced the character in the english dubs of ''Top Cat: The Movie'' and ''Top Cat Begins''. Finally, in ''Jellystone!'', The character (now named Spooky) was voiced by Jenny Lorenzo.
** Officer Dibble was voiced by Allen Jenkins in the original series. His death in 1974 resulted in John Stephenson taking over the role in ''Top Cat and the Beverly Hills Cats''. Jeff Bergman voiced the character in a ''Web Premiere Toons'' short. Finally, in the English dubs of ''Top Cat: The Movie'' and ''Top Cat Begins'', the character was voiced by Bill Lobley.
* ''WesternAnimation/TotalDrama'' franchise:
** Original series:
*** Courtney was voiced by Rochelle Wilson (who would later portray Sugar) in the first two episodes of the series before Emilie-Claire Barlow took over the role starting from the 3rd episode.
*** In his first appearance in "Hook Line and Screamer", the Psycho Killer was voiced by Scott [=McCord=] (Owen & Trent). When he reappeared in the first episode of ''All-Stars'', Brian Froud (Harold & Sam) voiced him.
*** For ''Action'' through most of ''World Tour'', Alejandro was mainly voiced by Marco Grazzini, excluding the post-credits scene in "Hawaiian Punch" where Keith Oliver voiced him. In ''All-Stars'', Alex House took over the role.
*** After seven years voicing Chef, Creator/CleBennett was recast with Creator/DevenMack due to Bennett moving to the United States.
*** Since the start of the series, Chris [=McLean=] had been voiced by Christian Potenza, a tradition that continued all the way until ''Pahkitew Island''. Starting with the 2023 reboot of the series however, Chris is voiced by Creator/TerryMcGurrin. As explained by [=McGurrin=], this was a creative decision rather than an executive one. Potenza would later go on to state that while he had originally recorded voice lines for Chris for the reboot's first season, the reason he was recast was a mix of him losing interest in the franchise and sexual harassment allegations, which he stated are false, made against him that caused Fresh TV to cut ties with him.
*** The Italian dub replaced three of the contestants' voice actors. Corrado Conforti, who voiced Ezekiel in the first two episodes, was replaced by Gianluca Crisafi at the end of ''Island''. Laura Latini, who voiced Gwen, died in 2012; Roberta de Roberto took over for her in ''All-Stars''. And Creator/AlessiaAmendola, who was Lindsay, was not available for ''All-Stars'', so Valentina Mari replaced her.
*** The Polish dub replaced Sadie and Ezekiel's actors after ''Island''; while Geoff and Leonard's voices were changed for ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'' because of a change in dubbing studios. Also in ''Action'', Joanna Pach, Lindsay's voice actress, was replaced by Katarzyna Łaska for several episodes.
*** The Hungarian dub replaced Eva's voice after her first elimination, though the original actress would later voice Jo. Ezekiel, Beth, Tyler, and Sadie's voices also changed after ''Island''. Leonard was given Max's voice in ''The Ridonculous Race''.
*** The Hebrew dub goes through an extreme case. Owen and Scott were first voiced by Liron Lev; but starting in ''All-Stars'', both would be voiced by Daniel Magon. Noah was usually voiced by Zir Zohan Meir, but by Liron Lev in ''Action'' and Jonathan Magon (Daniel's brother, who had already been Topher) in ''The Ridonculous Race''. Orli Katan (who voiced Beth since the series's beginning) would also voice Katie and Eva during ''World Tour''. Gwen was initially voiced by Avital Abergel, but starting in ''Action'', Hilly Israel (who would also provide the voice for Tammy and Crimson) voiced her for the rest of the series. In her ''Revenge of the Island'' appearance, Rona Bekerman (who provided the voice for Anne Maria) also provided Gwen's voice. Michal Reshef retired from voice acting to focus on her music career after her cameo in ''Revenge of the Island''. As a result, Shahar Kadosh (who would later provide Sky and Sanders' voices) voiced Lindsay for ''All-Stars''. Since Dawn (who Reshef also voiced) hasn't appeared since ''Revenge of the Island'', there were never plans on what will happen to her in future episodes.
** ''[[WesternAnimation/TotalDramaPresentsTheRidonculousRace The Ridonculous Race]]'':
*** None of the classic cast members from the Romanian dub returned because the dub changed studios and cities.
*** In the Hebrew dub, Kelly and Rock's initial voice actors weren't present for the final episode. Instead, Kelly was voiced by Anat Niv, who was Josee, while Saar Badishi, who voiced Spud and Gerry, provided the voice for Rock.
*** In the Spanish dub, Josee is the only contestant to get a voice change when Creator/RebecaAponte (Katie and Blaineley) took over for Marycel Gonzalez after episode 21.
** ''WesternAnimation/TotalDramaRama'':
*** Brian Froud (Harold) which he revealed on Twitter as well as how he wanted to take part in the project only for Fresh TV to deny him. Harold is now voiced by Darren Frost (Chet).
*** Megan Fahlenbock (Gwen) which she not only confirmed on a (now deleted) Facebook post but also hinted that she was possibly fired from the role entirely thanks to "the network" (meaning either Teletoon and/or Cartoon Network). She was replaced by Lilly Bartlam. However, [[spoiler:Megan would voice her briefly for the ending of "Tiger Fail"]].
*** Cory Doran (Mike) replaces Carter Hayden as Noah.
*** Bahia Watson replaces Novie Edwards as Leshawna.
*** Clé Bennett (Chef) moved to Hollywood. He was replaced by Deven Mack.
*** Wyatt White replaces Peter Oldring as Cody.
*** [[spoiler:Katie Griffin (Mary & Miles) and Lyon Smith (Jay & Mickey) replace the unknown female VA and Neil Crone (Dwayne) as Duncan's parents]].
*** In the Spanish dub, almost everyone gets recasted. For example, Roger Eliud Lopez (Brick) now voices Chef Hatchet, while Arelys Gonzalez (Sky) became Gwen's new voice as of season 2. The only voice reprises in the show are Noah, Leshawna, Gwen (before said recast), and [=MacArthur=].
*** The Polish dub replaced every voice except for Owen, Chef, [=MacArthur=], and Don. Some of the replacements voiced the characters from the franchise before (e.g. Courtney's replacement VA voiced Zoey and Duncan's voiced Mickey and Jay).
*** The Hungarian dub replaced everyone, except for Owen and Chef. Some of the replacement actors had voiced past contestants: Courtney is voiced by the same actress as Kitty; Noah's voice actor voices [[WesternAnimation/{{Sixteen}} Jude]], while Junior's dubber voices Noah; Gwen is now voiced by Izzy and Taylor's dubber; [=MacArthur=] is now Emma; and Beth is voiced by the same actress as Katie.
*** In the Portuguese dub, only Noah and Courtney are recast, as Ettore Zuim (Noah's VA) now does voiceover work in Usefulnotes/SaoPaulo (just like Silvia Goiabeira, Lindsay's old VA), while Iara Rica (Courtney in the original series) was not considered for a RoleReprise in ''Total [=DramaRama=]''. Bridgette would have to be recast in the later episodes as her voice actress Ana Lucia Menezes unexpectedly passed away on April 20, 2021 after a COVID-19-releated stroke. For some reason in "[[Recap/TotalDramaRamaS1E23KnowItAll Know It All]]", Don is voiced by Raphael Rossatto instead of Daniel Muller.
*** The Hebrew Dub has half of the cast replaced. While Chef, Duncan, Cody, Courtney, Bridgette, Leshawna, and Izzy's voice actors/actresses return in their respective roles, Owen gets Lightning's voice, [[WesternAnimation/{{Sixteen}} Jude]] has Dwayne's voice actor, and Gwen is now voiced by the same actress who did Amy and Kitty. Noah, Harold, Beth, and [=MacArthur=] have new voice actors.
*** Unlike every other version, the Italian version replaced only four characters, where Bridgette is now voiced by Valentina Mari (who voiced Lindsay in ''All-Stars''), taking over for Creator/IlariaLatini; Creator/ManuelMeli (who was Lorenzo) now voices Jude in ''[=DramaRama=]'' instead his original voice actor Alessio Ward; Izzy is now voiced by Creator/RossellaAcerbo; and Owen is now voiced by Creator/MassimoDeAmbrosis.
* After ''WesternAnimation/TotallySpies'' moved recordings from Los Angeles to Toronto after 52 episodes:
** Alex went from being voiced by Katie Leigh to being voiced by Katie Griffin for the following episodes, and all other media.
** Jerry went from Creator/JessHarnell to Adrian Truss at the same time Alex's voice was also replaced.
** Jennifer Hale and Andrea Baker, however, continued their roles of Sam and Clover in separate recordings in Hollywood.
** In Poland the whole cast was replaced for Season 6 because the dub switched dubbing cities from Katowice to Warsaw.
* ''WesternAnimation/TheTransformers'': There were several cast changes for characters introduced in ''WesternAnimation/TheTransformersTheMovie'' when they carried over into the post-movie third season:
** Galvatron went from Creator/LeonardNimoy to Creator/FrankWelker (though one could argue that the character's VA went from Welker to Nimoy and back to Welker, since Galvatron is an upgraded Megatron).
** Ultra Magnus went from Robert Stack to Jack Angel.
** Unicron went from the late Creator/OrsonWelles to Roger C. Carmel.
*** After Carmel passed away during the third season, Angel took over Carmel's role of Cyclonus.
** Wreck-Gar went from [[Creator/MontyPython Eric Idle]] to Tony Pope.
** Rodimus Prime went from Creator/JuddNelson to Ted Schwartz initially, but he became TheOtherMarty when he was replaced with Dick Gautier.
** Kup went from Lionel Stander to John Stephenson.
** The Italian dub cast was completely changed after fifteen episodes into Season 2. And some characters had multiple voice actors going back and forth for the remainder of the season (an extreme case is Optimus Prime having a different voice actor for ''5 random episodes''). The movie dub recast everyone again, but in Season 3 the few characters who were still around got their old voices back, except when Starscream's ghost came around and he has the voice from the movie (the voice actor was already around as Blurr and First Aid)
* The Italian dub of ''WesternAnimation/TrippingTheRift'' moved from Turin to Milan after season 1. Only Whip's voice actor returned.
* In the ''WesternAnimation/{{Unikitty}}'' TV series, Creator/TaraStrong replaces Creator/AlisonBrie as the voice of the titular character. Brie was also substituted by Creator/HyndenWalch for ''WesternAnimation/TheLegoMovie'''s video game adaptation.
* ''WesternAnimation/TheVentureBrothers'':
** Minor character Prof. Richard Impossible was voiced by Peter [=McCulloch=] in the pilot, Creator/StephenColbert in the first two seasons, Chris [=McCulloch=] (Jackson Publick) in the third season, and Bill Hader[[note]]the same one who was a cast member on ''Series/SaturdayNightLive'' from 2005 to 2013, known for his spot-on celebrity impressions and his cache of bizarre characters, from bitter, senile field reporter Herb Welch to burned-out, openly gay ClubKid Stefon Zolesky-[[Music/DavidBowie Bowie]][[/note]] in the fourth season.
** Publick also took over the voice acting duties for Sgt. Hatred in Season 3, who was voiced by Brendon Small during his first appearance, due to the fact that Brendon Small was busy working on ''WesternAnimation/{{Metalocalypse}}'':
** Both Dr. Girlfriend and Billy Quizboy were voiced by Chris [=McCulloch=] in the pilot episode, but by Doc Hammer on the rest of the show.
** Dean went through two voice actors in the short-lived Latin American dub: Luis Enrique Pojan for season 1, and Eder La Barrera for season 2 (Pojan had retired in 2007 and moved from Venezuela, where the dub was produced, to Spain).
* ''WesternAnimation/WhateverHappenedToRobotJones'':
** An unusual example happens with the title character. Robot Jones was "voiced" by a [[Platform/AppleMacintosh MacinTalk Junior]], then, the producers replaced it with a real voice actor for the remainder of the show, even going back and dubbing his voice over the show's old episodes, which didn't sit well with fans and led to the show's cancellation and descent into obscurity. It was rumored that Creator/CartoonNetwork got a cease-and-desist from Apple because the original voice of Robot Jones was from a Mac text-to-speech program, but, according to show creator, Greg Miller, the circumstances behind Robot Jones' voice change was actually a classic case of ExecutiveMeddling: Cartoon Network execs didn't like the text-to-speech robot voice, and wanted Greg Miller to change it to a human voice that's been altered to sound robotic.
** Also, Principal Madman and Mr. [=McMcMc=] were voiced by Creator/MauriceLaMarche in the pilot, but in the series proper, they were voiced by Creator/JeffBennett and Rip Taylor respectively.
* ''WesternAnimation/WhatsWithAndy'':
** The entire cast was replaced after the first season because Saban/Disney had sold the series rights to Cinegroupe, a Canadian animation studio (which co-produced the first season of the show). Therefore, all the Los Angeles actors (except Creator/IanJamesCorlett as the title character) were recast with Montreal talent.
** Similarly, the Mexican Spanish cast recast everyone but Andy's actor (Creator/EnzoFortuny) because the series had changed studios.
* ''Franchise/WinnieThePooh'':
** The title role was first provided by Disney veteran Sterling Holloway, who continued to voice the character until ''[[WesternAnimation/TheManyAdventuresOfWinnieThePooh Winnie the Pooh and Tigger Too]]'' in 1974. For ''Winnie the Pooh and a Day for Eeyore'', released nine years later, Holloway was replaced by Hal Smith, who also voiced Owl. Smith woud voice Pooh again in the live-action series ''Welcome to Pooh Corner''. After Holloway retired during production of ''WesternAnimation/TheNewAdventuresOfWinnieThePooh'', Creator/{{Jim Cummings|1952}} took over the role for the series and has voiced the character ever since. Oddly, some episodes of ''New Adventures'' feature Smith voicing Pooh during the times Cummings was absent.
** As mentioned above, Cummings also replaced Creator/PaulWinchell as the voice of Tigger following his retirement in 1999. Before then, he filled in for Winchell during the latter two seasons of ''New Adventures'' when he left the series following a massive stroke, and would fill in for him again in ''Boo to You Too!'' and ''Seasons of Giving'' so that he could watch his health. According to Cummings, before his career-threatening stroke, Winchell would also not be available during some recording sessions of ''New Adventures'' to do charity work in Africa, so Cummings would also fill in for him during those times as well. In ''Welcome to Pooh Corner'', however, Will Ryan voiced Tigger.
** Andre Stojka voiced Owl from Hal Smith's death in 1994 all the way until the [[WesternAnimation/WinnieThePooh2011 2011 animated film]], where Creator/CraigFerguson replaced him from that point onwards. Prior to that, Smith was the only actor to reprise his role in all ''Winnie the Pooh'' media up to that point.
** Piglet was voiced by John Fiedler until his death in 2005, making him the longest-serving voice actor of the franchise to date. Travis Oates has voiced the character since then. However, in ''Welcome to Pooh Corner'', Phil Baron provided his voice.
** Rabbit was voiced in the featurettes by Junius Matthews. After Matthews died, Will Ryan voiced the character in both ''Winnie the Pooh and a Day for Eeyore'' and ''Welcome to Pooh Corner''. With ''New Adventures'', Ken Sansom became Rabbit's voice until he was unceremoniously replaced by Creator/TomKenny in the [[WesternAnimation/WinnieThePooh2011 2011 animated film]]. With Sansom passing away the following year, Kenny has voiced Rabbit ever since.
** Eeyore was voiced by Disney storyboard writer Ralph Wright in all of the featurettes up to ''A Day for Eeyore'', before passing away not long after its release. For ''Welcome to Pooh Corner'', Ron Gans provided his voice. Beginning with ''New Adventures'', Eeyore was voiced by Creator/PeterCullen until he was replaced by Bud Luckey in the [[WesternAnimation/WinnieThePooh2011 2011 animated film]]. However, as of 2017, Cullen has returned to voicing Eeyore full-time although Creator/BradGarrett has occasionally filled in for him whenever he was busy.
** Gopher was voiced in the original featurettes by Howard Morris. When he returned in ''New Adventures'', Creator/MichaelJGough replaced Morris due to the latter being locked in a contractual commitment to ''WesternAnimation/GarfieldAndFriends'', where he voiced Wade Duck. Gough has voiced Gopher ever since.
** Kanga was originally voiced by Barbara Luddy in the first three featurettes, but due to her death in 1979, was replaced by Julie [=McWither=] Dees in ''A Day for Eeyore''. Diana Hale voiced her in ''Welcome to Pooh Corner'' and was herself replaced by Pat Parris in ''New Adventures''. Since then, Kanga has mainly been voiced by Creator/KathSoucie, Creator/TressMacNeille, and as of the [[WesternAnimation/WinnieThePooh2011 2011 animated film]], Kristen Anderson Lopez.
** Roo is a justified example given his tendency to be voiced by [[ChildrenVoicingChildren actual children]], but in chronological order, he's been voiced by Clint Howard (featurettes barring ''A Day for Eeyore''), Dick Billingsley (''A Day for Eeyore''), Kim Christianson (''Welcome to Pooh Corner''), Nicholas Melody (''New Adventures''), Kylie Dempsey (a variety of 90's spinoff material), Nikita Hopkins (his main voice actor throughout the late 90's-early 2000's), Jimmy Bennett (most mid-2000's material including ''VideoGame/KingdomHeartsII''), Max Burkholder (''WesternAnimation/MyFriendsTiggerAndPooh''), Wyatt Dean Hall (the [[WesternAnimation/WinnieThePooh2011 2011 animated film]]), and Aidan [=McGraw=] (''VideoGame/KingdomHeartsIII''-present).
* ''WesternAnimation/WinxClub'': While the current Nick version has had a consistent cast, both the earlier 4Kids and Cinelume English versions had recasts:
** In the 4Kids version, Caren Manuel voiced Stella for the first season, but she was replaced by Christina Rodriguez for the last two seasons of the 4Kids run, though Manuel did continue her role of Darcy. In addition, Dani Schaffel quit her role as Tecna after the second season, and the character was voiced by Rebecca Soler for the third and final season of 4Kids version.
** In the Cinelume English version created for international markets, Bloom was notably voiced by Helena Evangeliou for the first 3 seasons of the show before taking leave and was replaced with Angela Galuppo for the fourth season. Lezlie Karls voiced Tecna for all of the first season, as well as a few episodes of the second before she left, the role subsequently went to Jodie Resther for the rest of Season 2, as well as all of seasons 3 and 4. Sarah [=McCullough=] voiced Musa until a few episodes into the third season before the character was recast with Anik Matern. The entire cast was different for the movies, which were dubbed using actors commonly found in anime (Creator/CindyRobinson, Creator/ChristopherCoreySmith, Creator/StephanieSheh, Creator/ErinFitzgerald, etc).
* WesternAnimation/WoodyWoodpecker has had several different voice actors.
** His original was the legendary Creator/MelBlanc, who left after the first three shorts (1940's "Knock Knock" and 1941's "Woody Woodpecker" and "The Screwdriver") when he signed an exclusive contract with Warner Bros. (though his version of Woody's laugh and many of the other vocal effects he did would continue to be used for years afterwards).
** Following Blanc' departure, radio comedian Danny Webb inherited the role for one short (his rendition of the Woody feature in 1941's "Pantry Panic", donning a voice relatively close to Blanc's original), followed by then-18-year-old voice actor and impressionist Kent Rogers for five shorts (spanning from 1942's "The Hollywood Matador" to "The Dizzy Acrobat" the following year). After Rogers was drafted, voice actor Dick Nelson voiced Woody in "Ration Bored" and in response to this and Rogers drafting (and, potentially, Lantz's own concerns over the financial dimensions of hiring another radio professional to perform Woody's voice), Ben Hardaway, then the studio's head storyman, inherited the role from 1944's [[WesternAnimation/TheBarberOfSeville "The Barber of Seville"]] to 1949's "Drooler's Delight", the final short produced by the studio before its temporary shutdown from 1948-50.
** When the studio came back, Creator/WalterLantz's wife [[CrossdressingVoices Grace Stafford]] became his permanent voice for the remainder of the theatrical series (which ended in 1972) and even into the early 1990s (though his cameo in ''Film/WhoFramedRogerRabbit'' was done by Cherry Davis).
** In more modern times, Creator/BillyWest has done Woody in ''The New Woody Woodpecker Show'' while Creator/EricBauza took the role in the 2018 live action/animation film ''Film/WoodyWoodpecker'' and the 2018 webtoons.
** Woody's co-stars have also switched up voice actors. In ''The New Woody Woodpecker Show'', Wally Walrus and Buzz Buzzard were Billy West and Creator/MarkHamill respectively, but in the 2018 webtoons, they become Creator/TomKenny and Creator/KevinMichaelRichardson. Meanwhile, Winnie Woodpecker was Creator/BJWard in the ''The New Woody Woodpecker Show'', but is replaced in the webtoons by Creator/TaraStrong.
* ''WesternAnimation/WowWowWubbzy'' had this happen to the Latin Spanish dub: Season 1 was dubbed in Venezuela while Season 2 was dubbed in Chile. As a result, the cast was replaced.
* ''WesternAnimation/XMenTheAnimatedSeries'':
** Gambit was first voiced by Chris Potter, but was voiced by Tony Daniels in the final season.
** Iona Morris voiced Storm in the first season and the first few episodes of the second one, but left the show and was replaced with Alison Sealy-Smith.
** Colossus was voiced by Rick Bennett in his appearance in "The Unstoppable Juggernaut", while Robert Cait voiced him in "Red Dawn"
** Randall Carpenter voiced Mystique in the first two seasons, while Jennifer Dale voiced her for the remainder of the show.
** Master Mold gets a new voice actor in season 4, who sounds completely different. Justified as it's a new model of Master Mold made after the original was destroyed.
* While the upcoming SequelSeries ''WesternAnimation/XMen97'' sees much of the original cast return, a large number of roles were recast:
** Due to Creator/NormSpencer, Creator/DavidHemblen and Marc Strange all having passed away, their respective roles of Cyclops, Magneto and Forge are taken over by Creator/RayChase, Matthew Waterson and Creator/GilBirmingham. Similar, Creator/EricBauza replaces the late David Fox as the Sentinels and Master Mold.
** Due to believing the role should go to an Asian actress this time, Creator/AlysonCourt declined to voice Jubilee, with Holly Chou taking over the role instead. However, Court does still appear in the show as the voice of Abscissa.
** Creator/JenniferHale replaces Creator/CatherineDisher as Jean Grey. Like Court, Disher instead voices a different role: Val Cooper.
** Isaac Robinson-Smith replaces Philip Akin as Bishop, AJ [=LoCascio=] replaces Creator/ChrisPotter as Gambit, JP Karliak replaces Robin Rubin as Morph and Creator/RossMarquand replaces Creator/CedricSmith as Professor X. Potter, and Rubin are still in the cast, however, now playing Cable and Robert Kelly, respectively (replacing Lawrence Bayne and Len Carlson in the process). [[spoiler:Marquand also replaces Creator/NeilRoss, Creator/SimonTempleman, and (unavoidable, given his stroke and resultant retirement) Creator/TomKane as Dr. Doom.]]
** Despite Creator/TaraStrong still being active, Creator/CourtenayTaylor replaces her as Magik. Likewise, Taylor replaces Creator/SusanRoman as Callisto.
** Bolivar Trask is now voiced by Gavin Hammon instead of Brett Halsey.
** Creator/ToddHaberkorn replaces Barry Flatman as Henry Peter Gyrich.
** Shard is now voiced by Creator/KimberlyWoods instead of the late Kay Tremblay.
** Creator/DavidErrigoJr replaces Creator/JohnStocker, Peter Wildman, Phillip Williams, and Creator/RichardEpcar in the respective roles of Leech, Mojo, Banshee, and Gladiator.
** Creator/AbbyTrott replaces Cynthia Belliveau as Spiral.
** Martha Marion replaces Lally Cadeau and Creator/TraceyMoore in the respective roles of Moira [=MacTaggert=] and Emma Frost.
** Creator/TravisWillingham replaces David Bryant as Sebastian Shaw.
* ''WesternAnimation/XiaolinChronicles'': Apart from Creator/TaraStrong as Omi and Creator/JenniferHale as Katnappe, ''none'' of the original voice actors from ''WesternAnimation/XiaolinShowdown'' return to reprise their roles in the English version. Many have said that this is due to a Canadian law preventing voice actors without Canadian citizenship from appearing in animated projects (although whether such a law exists is in doubt as there are quite a few Canadian voice actors who were born overseas).[[note]]It's worth noting most of the replacement actors [[LoopholeAbuse also have dual citizenship, possibly in an attempt to tie into the series's US roots]].[[/note]]
* ''WesternAnimation/YakkyDoodle'':
** The title character was first voiced by Jimmy Weldon. However, Weldon did not return to voice the character in ''WesternAnimation/YogisArkLark'' or ''WesternAnimation/LaffALympics''. Walker Edmiston and Frank Welker voiced the character in those 2 respectively. Jimmy Weldon did came back to voice the character two more times in ''Yogi's All Star Comedy Christmas Caper'' and ''WesternAnimation/YogisTreasureHunt''. In ''WesternAnimation/HarveyBirdmanAttorneyAtLaw'', Yakky had 2 voice actors, Chris Edgerly and then Steve Blum. Blum also voiced the character in the video game. In ''WesternAnimation/{{Jellystone}}'', the character is now voiced by Katie Grober.
** Chopper was first voiced by Vance Colvig. Colvig came back to voice the character in ''Yogi's Treasure Hunt''. Angelique Perrin voiced the character in ''WesternAnimation/{{Jellystone}}''.
* ''WesternAnimation/{{Young Justice|2010}}'':
** [[ComicBook/{{Shazam}} Captain Marvel/Shazam]] was initially voiced by Creator/RobLowe, but was recast with his brother Creator/ChadLowe after the former became unavailable due to other commitments. His child alter ego Billy Batson, meanwhile, was voiced by Robert Ochoa in Season 1, with Chad Lowe again taking over as Billy in Season 3 due to the character having aged to young adulthood. An illusion of Billy as a child in Season 4 was then voiced by Eric Lopez.
** Rocket was voiced by Miss Kittie[[note]]Kali Troy[[/note]] in Season 1, but was replaced by Denise Boutte starting in Season 2.
** ComicBook/TheFlash was voiced by Creator/GeorgeEads for most of the first two seasons, but was replaced by Creator/JamesArnoldTaylor starting in the Season 2 finale. Arnold also took over as G. Gordon Godfrey after Creator/TimCurry, Godfrey's original voice actor, suffered a stroke in 2012.
** ComicBook/{{Deathstroke}} was initially played by Creator/WentworthMiller, but the role was quickly taken over by Creator/FredTatasciore.
** In the first two seasons, Beast Boy was voiced by child actor Logan Grove. However, due to Grove retiring from acting after the second season was produced, Creator/GregCipes was hired to replace him starting in Season 3.
** Vandal Savage was voiced by Creator/MiguelFerrer in the first two seasons, but his death in 2017 necessitated Creator/DavidKaye taking over the part from season 3 onward.
** Creator/HyndenWalch replaced Creator/ArielWinter as Princess Perdita starting in Season 3.
** The Brain was voiced by Creator/NolanNorth in his first appearance, with Creator/CoreyBurton replacing him in all subsequent appearances.
** Lian Nguyen-Harper and Hawkwoman were initially voiced by Creator/KellyHu and Creator/DanicaMcKellar, respectively, but both parts were taken over by Creator/ZehraFazal starting in Season 3.
** The Ultra-Humanite originally just communicated in apelike grunts, which were provided by Creator/DeeBradleyBaker. However, when he finally spoke in Season 3, his voiced was provided by series creator Creator/GregWeisman.
** Rocket's son Amistad was voiced by Creator/KharyPayton in his first appearance, which quickly became the subject of memes due to the very jarring VocalDissonance. In season 4, the part was recast with Kurtis Mansfield, who has a much more appropriate voice for a young child.
** A retroactive example thanks to CanonWelding. [[spoiler:Season 4 revealed that ''Young Justice'' is part of the same continuity as ''WesternAnimation/GreenLanternTheAnimatedSeries'', with Creator/KevinMichaelRichardson and Creator/JasonSpisak reprising their respective roles as Kilowog and Razer. However, Carol Ferris and Guy Gardner had already appeared in prior seasons of ''Young Justice'' with their voices provided by Creator/KariWahlgren and Creator/TroyBaker, rather than Creator/JenniferHale and Creator/DiedrichBader, who voiced them in ''Green Lantern''.]]

[[folder:George Floyd-related examples]]
In the wake of the George Floyd protests throughout 2020, several shows announced that their non-white characters will no longer be voiced by white actors and will be recast. These include:
* ''WesternAnimation/BigMouth'': Creator/JennySlate announced she would no longer be voicing the biracial character of Missy, who was eventually recast with Ayo Edebiri.
* ''WesternAnimation/CentralPark'': The same day as the ''WesternAnimation/BigMouth'' announcement, it was announced that Creator/KristenBell, who is also white, would no longer be voicing the biracial Molly. She was recast with Emmy Raver-Lampman, with [[RecastAsARegular Bell voicing a new character, Abby Hunter, who's Paige's sister, in season 3]].
* ''WesternAnimation/BobsBurgers'': Series creator Loren Bouchard announced on Twitter that David Herman and Katie Crown, who are both white, would no longer play transgender sex worker Marshmallow and the student Harley, who are both black, respectively in the future after replying to a tweet about recasting Marshmallow and Harley with "Yes. On it." Marshmallow is now voiced by trans-femme model Jari Jones, while Harley and Ms. Jacobson (who was originally played by Melissa Bardin Galsky) are now both voiced by Ashley Nicole Black. Pamela Adlon also stepped down as the voice of Olsen Benner, with the role now being played by Nicole Byer.
* ''WesternAnimation/FamilyGuy'': Cleveland Brown has been recast after Mike Henry agreed to step down from the role. He is now voiced by Arif Zahir.
* ''WesternAnimation/TheSimpsons'': Hank Azaria already announced he will no longer voice Apu in 2019, in the wake of the documentary that pointed out the character's racial stereotypes. In June 2020 the show-runners announced that all of the show's non-white characters will be recast. Creator/AlexDesert took over Carl and Lou, Bumblebee Man is now played by Mexican-American actor Eric Lopez, Comic Book Guy's Japanese-American wife Kumiko, initially voiced by Creator/TressMacNeille, is now played by Japanese-American voice actress Creator/JennyYokobori, and Dr. Hibbert is now voiced by Creator/KevinMichaelRichardson. Hubert Wong, previously voiced by Tress [=MacNeille=], is now voiced by Rosalie Chiang (best known as "Meilin Lee" from ''WesternAnimation/TurningRed'').
* ''WesternAnimation/DanielTigersNeighborhood'': Markeda [=McKay=] replaced Addsion Holley as Miss Elaina starting with the fifth season.
* ''WesternAnimation/PAWPatrol'': Kim Roberts replaced Deann Degruijter as Mayor Goodway starting with "Pups and the Big Bad Bird Crew".
* ''WesternAnimation/MiraculousLadybug'': Creator/ZenoRobinson replaced Creator/BenDiskin as the voice of Nino Lahiffe/Carapace and Max Kanté/Pegasus as of the special "[[Recap/MiraculousLadybugSP01MiraculousWorldNewYorkUnitedHeroez Miraculous World: New York – United HeroeZ]]". Interestingly, Diskin himself asked the crew for Nino and Max to be recasted.
* ''WesternAnimation/VeggieTales'': David Mann replaced Phil Vischer as Mr. Nezzer for ''WesternAnimation/TheVeggieTalesShow''. Inverted in that the re-casting happened ''before'' the George Floyd protests, as Vischer was no longer comfortable impersonating an African-American (his portrayal of Mr. Nezzer was based on Ken Page, he of [[WesternAnimation/TheNightmareBeforeChristmas Oogie Boogie]] fame). That said, Vischer did occasionally reprise his role as Mr. Nezzer whenever Mann was unavailable.
* ''WesternAnimation/TheLoudHouse'' and ''WesternAnimation/TheCasagrandes'':
** As mentioned in the ''The Loud House'' page, Creator/NikaFutterman stepped down from voicing Alexis Flores due to the George Floyd protests, and was thus replaced by Diego Olmedo, who himself was replaced by Connor Andrade.
** The unnamed Theatre Club teen girl was initially voiced by Creator/JessicaDiCicco in "Party Down", and was recast following the George Floyd protests, now voiced by Creator/KimberlyBrooks.
* ''WesternAnimation/JohnnyTest'': After having voiced the character for the entirety of the show's original 2005-14 run, Creator/ScottMcNeil decided to step down from playing Mr. White, with the role going to Creator/DevenMack for the 2021 revival. Despite that, Scott continued to voice other characters on the show like Zizrar.
* ''WesternAnimation/AdventureTime'': Originally voiced by Creator/RebeccaSugar in the "Stakes" mini-series, Marecline's mother would be voiced by Creator/EricaLuttrell for the ''Distant Lands'' sequel series.
* ''WesternAnimation/WildKratts'': Sabryn Rock replaced Heather Bambrick as Koki starting with "Cats and Dogs".
* ''WesternAnimation/CloneHigh'': Creator/MitraJouhari replaces Creator/ChristaMiller, who would eventually voice Candide Sampson, as Cleopatra for the 2023 {{revival}} season.
* ''WesternAnimation/BubbleGuppies'': Throughout the show's original and revived run, Oona had been voiced by a few young white actresses (Reyna Shaskan in seasons 1-2, Tori Feinstein in seasons 3-4 and Colby Kipnes in season 5 to mid-season 6) until mid-season 6 where she is voiced by Mia Lynn Bangunan, an actress of Asian descent.
* ''WesternAnimation/TheProudFamily'': Aiden Dodson and Bresha Webb both replaced Creator/TaraStrong as [=BeBe=] and [=CeCe=] Proud respectively in the ''Louder and Prouder'' revival series.
* ''WesternAnimation/{{Futurama}}'': Feodor Chin replaced Creator/BillyWest as Leo Wong starting with "Children of a Lesser Bog" as well as Creator/MauriceLaMarche's Scoop Chang from "Rage Against the Vaccine". Creator/KevinMichaelRichardson replaced Creator/JohnDiMaggio as URL starting with "I Know What You Did Next Xmas", and [=DiMaggio=]'s Barbados Slim "Rage Against the Vaccine". The show was fortunate in that Amy Wong and Hermes Conrad were originally and remain voiced by Creator/LaurenTom and Creator/PhilLaMarr, respectively.
* ''WesternAnimation/XMen97'' sees Holly Chou replace Creator/AlysonCourt as Jubilee, with Court having given her blessing.
