History Main / AlienAmongUs

* This is the plot of VideoGame/AmongUs. Imposters are unidentifiable from other crewmates. At least until they reveal themselves in one of their kill animations.

%%Among Us is not an example. This is a Fish Out of Water trope about when an alien is peacefully living on Earth.

Compare FirstContact. See also AmusingAlien, HumanityEnsues, RaisedByWolves, FishOutOfWater, MysteriousWaif.

** ''Film/ManOfSteel'': the film plays more like a "first contact" AlienInvasion film, and Zod tells humans that one of his specis has been living among them unbeknownst to them.

* On the short-lived Jim Henson Productions sitcom ''Aliens in the Family'', an alien and a human fall in love and form a blended family. Oddly enough, their family (which includes a {{Muppet}} baby and two older aliens in full body costumes) lives on Earth.

* ''LightNovel/HaruhiSuzumiya'': Yuki has the major stuff down, but when you get down to the details like how a computer is used or maybe what a glasses fetish happens to be...also Kuyou, the resident StarfishAlien, who is so different that she can't really have the concepts explained to her.

* In ''VideoGame/AmongUs'', anywhere from 1 to 3 players play as Impostors, alien shapeshifters presumably who can take on the appearance of other Crewmates. Their job is to stealthily infiltrate among the Crewmates and either kill them off personally or get them to vote themselves off.[[/folder]],

** Subverted in ''[[ComicBook/Supergirl2005 the fifth volume]]''. At the beginning, Supergirl feels she doesn't understand Earth or Terrans and she doesn't fully fit in. But then ''[[ComicBook/SupermanBrainiac she and Superman rescue]]'' ''[[ComicBook/NewKrypton Kandor]]'' and Kara finds she doesn't fit in with Kryptonians anymore either because she got used to think and act like an Earth woman.

* ''Film/TheCatFromOuterSpace'' has the alien cat Jake crash-landing on Earth. Aware that his presence may cause conflict, so he tries to leave as quickly and quietly as possible.

* Lala from ''Anime/StarTwinklePrettyCure'' is a HumanAlien who lands on Earth and befriends the human PinkHeroine, Hikaru. She averts AliensSpeakingEnglish at first, but once the two of them become {{Magical Girl Warrior}}s, the TransformationTrinket takes care of translating. Though there's an AlienNonInterferenceClause, she gets around it by enrolling into school, where her odd behavior sometimes raises eyebrows. She also brings along the squid-like alien Prunce, who usually disguises himself as Lala's backpack. Later on, they also take in a CatGirl alien named Yuni, who doesn't enroll in school and just kind of hangs out in tree branches until she's needed.

* ''VideoGame/AmongUs'' is about a group of crewmates who are out to do their job, but there is an impostor among them. Impostors are aliens that resemble the crewmates in almost every way but are out to kill them.

* This was the starting premise of Creator/KenichiSonoda's ''Manga/CannonGodExaXxion'' manga, where aliens called the Riofaldians came to earth in peace, bringing their advanced technology with them and have been coexisting with humans on earth for several years. Of course, they were secretly infiltrating us to set us up for conquest all along (the weapons technology they gave us is ineffective against their REAL weapons) and this appears to be standard operating procedure for them.

* In the french cartoon "Jamie's Got Tentacles", has Jamie, an alien prince who is hiding on Earth from aliens who want to eat him. He befriends a human boy called Erwin and lives with him in his house while wearing a human costume. Most plots are usually about Erwin trying to stop other people from finding out Jamie is an alien.

* ''Series/{{Tracker}}'': Cole/Dagon doesn't really make much effort to blend into human society. His speech is strange and monotonous, although it gets better in later episodes. He has trouble understanding things we take for granted (such as trying to explain to Mel, who knows who he really is, what ''Franchise/StarWars'' is). Even ''bathing'' is new to him. I guess they don't do that on Cirron. It's a lot easier for the alien fugitives, since they were forced to take human bodies to survive and absorbed their skills and memories. Cole arrived on his own and took on human form from an underwear ad.
