History AdaptationSpeciesChange / WesternAnimation

* One of the few things we know about the never fully released ''WesternAnimation/ToonMakersSailorMoon'' is that Luna from ''Manga/SailorMoon'' would have gone from being a black short-haired cat to a white longhaired one.

* ''WesternAnimation/SpiderManTheAnimatedSeries'' sees Madame Webb, a {{mutant}} in the comics, reimagined as a cosmic entity like the Beyonder.

* ''[[WesternAnimation/GarfieldSpecials Garfield's Babes and Bullets]]'' deviates from the prose story in the ''ComicBook/GarfieldHis9Lives'' graphic novel by making the rest of the cast human with Garfield being the only cat, when all characters were originally all cats.

** While originally seemingly human, ''WesternAnimation/GIJoeTheMovie'' retconned Cobra Commander into a snake person from the ancient civilization of Cobra-La. Fans and Creator/LarryHama, who helped create the characters for [[ComicBook/GIJoeARealAmericanHero the comics]] and cartoon (even writing the original version of the former) hated the Cobra-La origin and every other iteration has kept the Commander human.

* ''WesternAnimation/SheRaPrincessOfPower'' has Catra as a human woman who can transform into a feline beast using a magical mask. The 2018 reboot ''WesternAnimation/SheRaAndThePrincessesOfPower'' has her as a CatGirl with regular does of FurryReminder.

* ''Toys/TheTrashPack'' Mondo TV Cartoon plays for an...interesting version of this idea. As the core chunk of Trashies are [[AnimateInanimateObject Animate Inanimate Objects]] anyways, Putrid Sardine, originally a can of sardines in the toyline, is instead adapted into a juice box in the cartoon. He still keeps his oozy green juice and dent-formed unibrown, however.

** ''WesternAnimation/XMen'' makes a few characters who weren't mutants in the comics into mutants, such as the Purple Man. An inverse example is Silver Samurai, who is a mutant in the comics, but was depicted as a human with a teleportation device in the show.

* In Marvel Comics, Iron Man villain the Ghost is a human in a high-tech stealth suit. The ''WesternAnimation/AvengersAssemble'' version starts out as this, before turning out to be an [[Comicbook/TheInhumans Inhuman]] and gaining innate phasing abilities through terragenesis.

* ''WesternAnimation/PhineasAndFerbStarWars'' changes [[MadScientistsBeautifulDaughter Vanessa]] into a Twi'lek (or maybe [[HalfHumanHybrid half-Twi'lek]], if you assume that "[[MadScientist Darthenshmirtz]]" is still her father).

* ''WesternAnimation/StarWarsTheCloneWars'': In ''[[Franchise/StarWarsLegends Legends]]'', the old ''Star Wars'' ExpandedUniverse, [[DarkActionGirl Asajj Ventress]] was Rattataki and [[spoiler:Darth Maul]] was a pure Zabrak. In this show, they were both {{retcon}}ned into Dathomirians. This is downplayed in Maul's case, as the Dathomirians are a Zabrak subspecies ([[HalfHumanHybrid Zabrak-human hybrids]] in pre-''Legends'' supplementary material), with [[BizarreSexualDimorphism the males looking more like their Zabrak ancestors]], and a lot of characters unfamiliar with Dathomirians assume Maul to be an Iridonian Zabrak as a result.

* ''WesternAnimation/SheRaPrincessOfPower'' has Catra as a human woman who can transform into a feline beast using a magical mask. The 2018 reboot ''WesternAnimation/SheRaAndThePrincessesOfPower'' has her as a PettingZooPerson who regularly exhibits cat-like behaviors.

** In ''WesternAnimation/RiseOfTheTeenageMutantNinjaTurtles'', the titular four are specific species, and each one's is different. Leonardo is a red-eared slider, Raphael a snapping turtle, Donatello a soft-shelled turtle, and Michaelangelo a box turtle. This becomes more complicated when it turns out ''all'' the {{mutants}} (though made in the same way) are artificial {{youkai}}, and the turtles specifically are also [[MixAndMatchMan artificial]] {{Half Human Hybrid}}s.

* ''WesternAnimation/IronManArmoredAdventures'' made several of Iron Man’s human enemies from the comics like Grey Gargoyle, Dreadknight and Firebrand into ancient creations of the original Mandarin.

* In ''Anime/{{Voltron}}'', Allura and Coran are [[HumanAliens Arusians]]. In ''WesternAnimation/VoltronLegendaryDefender'', they're the [[LastOfHisKind last of the]] [[RubberForeheadAliens Alteans]]. Note that "Altean" [[DevelopmentGag was what their species was called in]] ''Anime/GoLion'', and ''Legendary Defender'' uses the name "Arusian" for a non-humanoid race. Additionally, [[spoiler: Keith, who was fully human in the original, is now a [[HalfHumanHybrid human/galra hybrid]]]].

** In ''WesternAnimation/RiseOfTheTeenageMutantNinjaTurtles'', the titular four will become different turtle species. Leonardo, Raphael, Donatello and Michaelangelo are now respectively a red-eared slider, a snapping turtle, a soft-shelled turtle and a box turtle.
