History Main / AlienAnimals

If the alien doesn't naturally resemble an animal but has disguised itself as one through VoluntaryShapeshifting, then TheDogIsAnAlien. If the alien looks like an animal but isn't on Earth posing as one, it's probably an IntelligentGerbil. If the alien animals are a certain species of great ape, see HumanityCameFromSpace.

* In the game ''Sheep'' you have to lead the sheep, who have become stupid in the time they were on Earth, back to their home planet.

* ''VideoGame/CthulhuSavesTheWorld'' features Ultharians, who look like Earth cats, but they are green and have black eyes and they can turn their tails into CombatTentacles. [[CatsAreMean They also like taking over the planets]]. Notably, [[MySpeciesDothProtestTooMuch Paws was tired of this lifestyle]] and joins Cthulhu's party. Ultharians, Paws included, also reappear in ''VideoGame/CosmicStarHeroine'' as harmless, albeit still kinda rude, [=NPCs=].

* In the animated series of ''WesternAnimation/MenInBlack'' it is revealed that Frank the Pug looks very much like a dog anyway underneath his disguise suit.
* On ''WesternAnimation/SouthPark'' Earth is revealed to actually be a massive, millennia-old alien reality show. Apparently every other planet only has one species--a planet of deer, a planet of Asians, etc.--and we're all just forced together so everyone can watch what happens.
* On ''WesternAnimation/TeenTitans2003'', an alien is visiting Earth when its intelligent pet, which looks like a green dog, escapes. Meanwhile [[{{Animorphism}} Beast Boy]], who can turn into a green version of any animal, is impersonating a dog. HilarityEnsues.

* ''WesternAnimation/{{Kaeloo}}'': In Episode 98, Stumpy comes up with the idea that all of Smileyland's sheep are aliens after an incident where they abduct him, but nobody believes him. [[spoiler:The entire episode turns out to be AllJustADream... until Stumpy gains a strange voice and swirling eyes when he tells Kaeloo she can play leapfrog along with him and the sheep, suggesting that the sheep really ''are'' aliens and Stumpy has been hypnotized by them.]]
* ''WesternAnimation/TheOwlHouse'': Eda tells Luz that giraffes were originally from the Boiling Isles, but were banished to Earth for being weirdos ([[HypocriticalHumor said the witch that later leaves her detached hand on her magic staff]]).

* On ''WesternAnimation/TeenTitans'', an alien is visiting Earth when its intelligent pet, which looks like a green dog, escapes. Meanwhile [[{{Animorphism}} Beast Boy]], who can turn into a green version of any animal, is impersonating a dog. HilarityEnsues.

->'''Talos:''' Oh my god! Get that thing away, how that get in here?\\

* A variation in Creator/LarryNiven's ''{{Literature/Protector}}'': [[spoiler:all primates, including humans,]] are distant descendants of a group of [[spoiler:Pak -- known to palaeontologists as ''Homo Habilis'' --]] whose spaceship crashed on Earth millions of years ago. It is speculated that the radiation from their power plants accelerated their evolution into new species. This is easily one of the largest ArtisticLicenseBiology ever taken by Niven, whose science-fiction is usually [[SlidingScale/MohsScaleOfScienceFictionHardness extremely hard]].

* In the ''VideoGame/{{Tamagotchi}}'' digital pet toys, the player can raise their Tamagotchi alien to grow into breeds that resemble Earth animals (such as Pochitchi, who looks like a dog).

* In one ComicBook/FantasticFour story Reed Richards hypnotized some alien shapeshifters called the Skrulls into thinking they were ordinary Earth cows. Years later those alien cows got mixed in with some Earth cows and some were slaughtered for beef. The alien flesh though gave some people a virus that allows them to [[CursedWithAwesome shapeshift their bodies into deadly weapons and detect hidden Bkrulls]].But this virus would also eventually kill them. The best part? [[ParanoiaFuel There is no way of telling which cow is a Skrull until you eat it]].

You have just encountered the Alien Animal. These {{aliens|AndMonsters}} don't have [[LittleGreenMen green skin]] or {{rubber forehead|Aliens}}s, they just look exactly like a specific type of animal. Maybe they make up the entire population of that animal on Earth or only part of them. Sometimes they are leaving Earth because they have knowledge about the impending {{end of the world}} and sometimes they just like [[AliensStealCable watching television]]. Just [[MST3KMantra relax]] and go with it.

** Downplayed by Hamsterweil who he looks rather like an Earth gerbil or hamster, but doesn't usually pose as an actual hamster or gerbil and doesn't look entirely consistent to any actual earth species of gerbil, let alone hamster. One episode has him being adopted by Mertle and put in a cage just like a hamster.

* ComicBook/KryptoTheSuperdog is (usually) a dog from Krypton and looks like an Earth-native dog even if he normally doesn't resemble a specific breed, though some artists make him look a lot like a yellow lab with abnormally pale coloring.

* [[MentorMascot Luna, Artemis and Diana]] from ''Franchise/SailorMoon'', who are revealed to come from the Planet [[{{Pun}} Mau]], Sailor Mars' pet Crows Phobos and Deimos may count as well.

There's an animal on this planet that's always looked harmless — rabbits or mice or squirrels or hamsters, it doesn't matter. One day, you'll be walking your corgi dog [[FluffyTheTerrible Mr. Flufferkins]] along and suddenly he'll look up at you and say, "Thank you, human, for this relaxing walk and all those times you've scratched my chin, but I'm afraid the [[ScaryDogmaticAliens Nogov 10th Brigade]] is coming here in [[TwoOfYourEarthMinutes five of your Earth minutes]] to [[EarthShatteringKaboom get rid]] of this [[InsignificantLittleBluePlanet small blue planet]] and replace it with a transgalactic outlet mall. However, this is good news: [[BadNewsIrrelevantNews you can spend your last five minutes secure in the knowledge that everyone will be getting cheaper outlets soon]]. Well, except the human race, of course, but these things have to be built. Goodbye." And then he disappears before your very eyes, along with every other corgi on the face of the Earth.

** A ''regular'' space hamster (i.e. a hamster living on a spaceship) resembling Boo makes an appearance in VideoGame/MassEffect2.

** Ordinary giant space hamsters does in fact exist in the setting (they were bred by a bunch of crazy gnomes to help power their spacefaring 'Jammers), as does miniaturisation magic, so a miniature giant space hamster could well exist. Unless Boo is an ''Awakened'' Miniature Giant Space Hamster, however, he should be just as intelligent as any hamster.

* ''WesternAnimation/LiloAndStitchTheSeries'': In the "Yapper" episode, Mertle's pet dog, Gigi, is revealed to be one of Jumba's experiments (Experiment 007), designed to look and act like a Shih-Tzu dog, annoying people with its constant yapping.

** In an interview, KA implied that ants evolved from the Nesk.

* A variant in ''Manga/FairyTail''. [[TeamPet Team pets]] Happy and Carla are thought to be cats native to Earthland, despite being able to talk, fly, and hatch from eggs (which in a world of dragons, Vulcan, and Celestial Spirits, isn't that strange). It turns out they are Exceeds, a race of cat-like creatures from the parallel world of Edolas, [[spoiler:sent to Earthland to escape a cataclysm fated to end their homeworld]].
