* The WesternAnimation/DonaldDuck cartoon "WesternAnimation/MrDuckStepsOut" featured the debut of Daisy Duck, where she was originally voiced by Donald's actor, Clarence Nash, talking in a similar garbled voice as Donald but pitched differently. However, there is also an altered version which has a voice actress dubbing over Nash's dialogue for Daisy and having her speak clearly as she did in all other appearances. The original version with Nash voicing Daisy is available on Creator/Disney+.

* In later airings of season 6 of ''WesternAnimation/{{Arthur}}'', in which the title character was originally voiced by Justin Bradley, over half of them were redubbed by his next voice actor Mark Rendall, as the producers thought Bradley's voice didn't match the youthful range ''Creator/Michael Yarmush'' had.

* In the ''WesternAnimation/JohnnyBravo'' episode "Bravo Dooby Doo", which features a cross over with the cast of ''Franchise/ScoobyDoo'', Creator/GregBurson was originally hired as the voice of Scooby but the executives at Cartoon Network thought he didn't sound enough like him so they hired Hadley Kay to replace him.

* In ''WesternAnimation/XMenTheAnimatedSeries'', Storm's voice actress changed from Iona Morris to Alison Sealy-Smith for the second season onwards.[[note]]Morris recorded her lines in New York, while the rest of the cast recorded their in Toronto. For Season 2, it was decided that it would be easier to just cast another actress from Toronto.[[/note]] The Season 1 episodes were redone so Sealy-Smith was heard in reruns. However, the DVD releases and Hulu have the lines that were recorded by Morris, making the versions of those episodes with Sealy-Smith as [[KeepCirculatingTheTapes hard to get your hands on]] as Morris' versions once were. If you [[OneHundredPercentCompletion don't feel like you have the whole series]] without having both versions, your work's cut out for you.

* Ted Schwartz was originally cast as Judd Nelson's replacement for Rodimus Prime following ''WesternAnimation/TheTransformersTheMovie'', but for some reason he was replaced by Dick Gauthier. However, for unknown reasons, his lines were still used in the recap portion of "Five Faces of Darkness Part 2", as well as one line in "Five Faces of Darkness Part 3."

* Creator/BrianDrummond was originally going to voice Cyclops in ''WesternAnimation/XMenEvolution'' and even recorded his dialogue for the first episode, but the role was eventually recast to Creator/KirbyMorrow leading to to everything being re-recorded.

** In the original series, Lucille Bliss had recorded six weeks' worth of dialogue for Elroy Jetson before she was fired following a dispute between her agent and the producers over her salary and billing.[[note]]The producers wanted her to use an alias to hide her gender.[[/note]] Bliss subsequently fired her agent, but it was too late. The part had already been recast with Daws Butler, and the character's age was slightly raised, and the episodes with Bliss were completely re-recorded with Butler. According to Bliss, the original recordings with her as Elroy were destroyed.

* Freddie Rodriguez originally voiced Pantha in the fifth season of ''WesternAnimation/TeenTitans'', as the creative team thought it would be funny for the character to have a masculine voice. [[ExecutiveMeddling For some reason or another]], the role switched over to Diane Delano and Rodriguez' two episodes ("Calling All Titans" and "Titans Together") were re-recorded with her vocals. Even so, fans were still confused as to whether Pantha was voiced by a man or a woman.

* ''WesternAnimation/BuzzLightyearOfStarCommand'' originally premiered with a TV movie entitled ''The Adventure Begins'', with Creator/TimAllen reprising his role as Buzz from the ''WesternAnimation/ToyStory'' movies. Creator/PatrickWarburton, who voiced Buzz in the series, originally voiced him in the movie to begin with, but Allen dubbed over Warburton's dialogue when it was released. When it was edited into syndication as a multi-part episode, Warburton's dialogue was left unchanged.

* A very controversial one happened in ''WesternAnimation/TheAvengersEarthsMightiestHeroes''. Creator/JoshKeaton had originally reprised his role from ''WesternAnimation/TheSpectacularSpiderMan'' as Spider-Man himself for the episodes "Along Came a Spider" and "New Avengers", plus the series finale, but then it was decided to have Creator/DrakeBell, who voices the character in ''WesternAnimation/{{Ultimate Spider-Man}}'', redub the lines. Between this, Creator/GreyDeLisle reprising the role of Betty Brant, and what little lines he had as a cop, evidence also points to Creator/DaranNorris, Keaton and [=DeLisle=]'s costar on ''Spectacular'', also having reprised his role as J. Jonah Jameson and similarly being redubbed with Creator/JKSimmons, who played the character in the [[Film/SpiderManTrilogy Sam Raimi films]] and on ''Ultimate''.

* Originally Tami Holbrook who voiced Tommy Pickles in the pilot short for ‘’WesternAnimation/{{Rugrats}}’’ voiced him for the first couple episodes, but it was decided that she wasn’t working out, so they hired ‘’Creator/ElizabethDaily’’ to replace her and re-dub her lines.

* In ''WesternAnimation/TheSpooktacularNewAdventuresOfCasper'' Stretch was voiced by Joe Nipote like in the movie, however in the episode "Ghostfather" one of Stretch's lines when he says "There's the kid, ok my creepy crew let's just Boo it" was done by ''Creator/RobPaulsen''.
* ''WesternAnimation/SquirrelBoy'': In the pilot "Kite Makes Right", Creator/RobPaulsen was the original voice of Rodney J. Squirrel. In the series proper, Creator/RichardHorvitz filled in.

* In the original seven-minute pilot of ''WesternAnimation/HiHiPuffyAmiYumi'', Ami and Yumi were voiced by actual Japanese women whose identities remain unknown. For the series proper, they were instead voiced by Creator/JaniceKawaye, who is of Japanese descent, and Creator/GreyDeLisle.

** Karri Turner was originally supposed to be the lead voice actress for ''South Park'' and appeared in the unaired pilot as Wendy, Ms. Crabtree, and the other female characters. She wound up replaced by Mary Kay Bergman in the series proper, as the creators felt her voice wasn't distinct enough. Interestingly, the first choice before Turner was Nancy Cartwright, who refused to work on the show due to its crude content. This may have been for the best, given what happened with fellow Scientologist Isaac Hayes, Chef's voice actor, after "Trapped in the Closet".

* In ''WesternAnimation/TheLooneyTunesShow'', Creator/GreyDeLisle was billed to reprise the role of Petunia from the ''Looney Tunes: Stranger Than Fiction'' movie. However, the character ended up being voiced by Katy Mixon.

* In the ''WesternAnimation/JohnnyBravo'' episode "Bravo Dooby Doo", which features a cross over with the cast of ''Franchise/ScoobyDoo'', Greg Burson was originally hired as the voice of Scooby but the executives at Cartoon Network thought he didn't sound enough like him so they hired Hadley Kay to replace him.

** Towards the end of "Mother Simpson", when Mona gets in the van, accidentally hitting her head and saying "D'oh!", Pamela Hayden voices her because Creator/GlennClose couldn't say "D'oh!" properly.

* In later airings of ''WesternAnimation/{{Arthur}}'' during the Justin Bradley episodes over half of them were redubbed by his then current voice actor Mark Rendall.

* ''WesternAnimation/InspectorGadget'':
** The pilot of ''Inspector Gadget'', where Gadget has a mustache, had three versions: one with Gary Owens as Gadget, one with Jesse White as Gadget, as well as a third one that used most of White's dialogue, but with Creator/FrankWelker redoing one line to explain why Gadget had a mustache (this one ended up being the final version). Otherwise, they are completely identical. Ironically, neither Owens nor White went on to become Gadget's voice for the final series (which was Don Adams).

* ''WesternAnimation/OKKOLetsBeHeroes'':
** Stephanie Nadolny was the voice of K.O. in the pilot "Lakewood Plaza Turbo". When the show was greenlit a couple years later, Nadolny was initially kept on as the voice of K.O., but due to scheduling conflicts, she was replaced by Courtenay Taylor. At least one of the episodes that the former recorded was redubbed by the latter.
** Throughout the episode "Legends of Mr. Gar", K.O.'s voice randomly switches back and forth between the two, presumably due to an oversight.

* In the original 1969 broadcast of the classic Christmas special ''WesternAnimation/FrostyTheSnowman'', Creator/JuneForay voiced Karen and some of the other children, while Creator/PaulFrees voiced some of the boys. For the 1970 broadcast, however, an unknown actress, a real child, was brought in to re-record all of Foray's dialogue as Karen. A real boy was also brought in to re-record some of the dialogue of a couple of the young boys. However, much of Foray's dialogue still remains in the current version, as some of her dialogue for some of the additional kids weren't redone, and a couple of her lines as Karen ended up slipping through.[[note]]Such as when she says "Oh no!" off camera when the kids were thinking of a name for their snowman.[[/note]] Foray had no idea why this was done, and the special is still broadcast with the redubbed Karen today. To this day, nobody knows the name of the voice actress brought in for the role, as the credits weren't modified to include her.

* ''Creator/MarkEvanier'' stated in one episode of ''WesternAnimation/GarfieldAndFriends'' Lorenzo Music was too ill to come to the recording session so he had ''Creator/FrankWelker'' record Garfield's lines for that episode. Once Lorenzo was well again, he re-dubbed the lines Welker had recorded. Evanier stated Welker did such a good job impersonating Music's voice he and the sound editors could barely tell them apart so a couple of Welker's lines as Garfield may have made it into the final cut. Welker eventually succeeded Music as Garfield a few years after the latter's passing.
