'''The Doctor:''' No, ''you'' look Time Lord. ''We'' [[InvertedTrope came first]].
-->-- ''Series/DoctorWho'', [[Recap/DoctorWhoS31E2TheBeastBelow "The Beast Below"]]
-->(quote paraphrased from [[Recap/DoctorWhoS30E15PlanetOfTheDead "Planet of the Dead"]])

When a creature from a planet other than Earth looks like a human, sounds like a human, acts somewhat like a human and gets confused for a human.

[[HumanOutsideAlienInside Their internal physiology]] may well be different, whether a little or a lot or just none, but otherwise they appear to be the genuine article.

In-story, this occasionally leads to a {{handwav|e}}ing story about how all the races have some common ancestor. Other times, it gets {{justified|Trope}} by using a TransplantedHumans story. Out-of-story, this is often explained by the fact that there are remarkably few non-humanoids in the Screen Actors' Guild or Creator/{{Equity}}, and by the fact that believable-looking, wildly-different-in-appearance aliens are incompatible with low budgets. Other explanations include the idea that a humanoid form is the natural result of any evolutionary path (HumansAreSpecial [[XMeetsY on]] EvolutionaryLevels). Recent research may hint at this being true to some extent; many species seem to be engineered by evolution for maximum fuel efficiency. The bipedal human body has remarkable agility and stamina for its size, though there are some notable flaws like weak joints and a narrow birth canal. Our impressive cognitive abilities and incredibly complex social structure evolved to counter these. There's also a real phenomenon known as "Convergent Evolution" whereby species that originated in different areas eventually develop into things that look similar because it's a useful form.

This trope also covers [[VoluntaryShapeshifting shape-shifters]] who [[CoconutSuperpowers budget-savingly]] stay in human form around humans.

In 1950's movies, this also could be used as an actual part of the theme of the story, as the idea that these sorts of aliens could pass completely for humans made a rather handy [[RedScare metaphor for Communism]].

In {{Anime}}, on the other hand, the trope is often invoked to show that humans and their alien enemies are NotSoDifferent.

In stories involving alien [[HollywoodCyborg cyborgs,]] the aliens are often human-looking in their original form, to emphasize that the conflict of the story is between their biological and cybernetic natures, and not mainly about the fact that they are aliens. Examples include the Kaleds who became [[Series/DoctorWho the Daleks,]] the original [[Series/DoctorWho Cybermen,]] the Galadorians from ''RomSpaceknight,'' the Nebulans from ''TheTransformers,'' the ''GoBots,'' and ''Franchise/StarTrek's'' Borg.

The bottom rung of the [[AlienTropes Alien ladder]], below RubberForeheadAliens and {{Intelligent Gerbil}}s. Note that, for this trope, the alien must be '''visually indistinguishable from a human'''. "Human, but with blue (or purple, orange, [[GreenSkinnedSpaceBabe green]], etc.) skin" falls under RubberForeheadAliens. Aliens with cultural rather than biological similarities fall under InexplicableCulturalTies.

Technically there could be another rung below this one on the [[AlienTropes Alien ladder]]: [[HumansAreWhite Caucasian Aliens]]. There are many fictional planets where the aliens not only look human, they are all Caucasian-looking. This is rife with UnfortunateImplications. The opposite situation, where the alien race is genuinely alien, but they are all African-looking, or Asian-looking, etc., is vanishingly rare (and would probably carry a ''different'' batch of UnfortunateImplications). Naturally, this varies by the location of production: Japanese science fiction has planets full of Japanese-looking aliens, Indian films have Indian-looking aliens, ''DoctorWho'' depicts an entire universe full of [[AliensSpeakingEnglish people with British accents,]] and so on.

Reasons for using this trope may vary. Sometimes it may make audience relate to the character better ([[UnfortunateImplications because people aren't going to like a character]] [[ButNotTooForeign who looks, you know, "different"]]) or to have the character live among ordinary humans without undue complications, or to make a human-alien romance more plausible and less squicky. Or it might just be because they can't afford the makeup and rubber foreheads. Or sometimes, [[TheyJustDidntCare well....]]

Contrast with StarfishAliens (where the aliens are nothing like humans), HumanoidAliens (where aliens have a similar shape, but not quite human), AmbiguouslyHuman (where it isn't made clear in-canon whether a culture are human-like aliens or human-descended), and HumanSubspecies.

This trope may be TruthInTelevision: for humans to be able to survive on a planet without {{terraform}}ing or protective technology the planet needs to have the correct conditions for humans to have evolved there. Some scientists believe that this means that if we find any human-inhabitable words there will might be aliens there that look just like us, or, at least, similar to some Earth animals.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* ''MagicalProjectS'' the people of the magical kingdom are referred as not being human (even tough besides having magic they are identical in every aspect)
* ''ToHeart2'' brings us Lucy Maria Misora, aka Ruuko Kireinasora.
* The Zentraedi of ''Anime/SuperDimensionFortressMacross''/''{{Robotech}}'' and its descendants are one of the clearer examples of the trope, straight down to the HandWave concerning their origins being linked to that of humanity. The primary physiological difference being that in their natural state they are ten meters tall, but can through an [[CloningBlues ill-defined process]] be shrunk down to roughly human size (or expanded back up). They also have a few physical traits (bright green hair, somewhat pasty blue or greenish skin tones) that don't appear in humans, but once they start interbreeding with humans, these traits are sometimes found in mixed-heritage children.
** In fact, most aliens met in ''Macross'' are human-looking due to their genes being messed with millenia ago by the Protoculture, who were biologically near-identical to humans (this is not a coincidence: they engineered the human race deliberately). The one alien race met that was not toyed with in its infancy by the Protoculture, the Vajra, are StarfishAliens.
* In the ''Anime/MazingerZ'' ''[[{{Mazinger}} universe]]'', ''[[Anime/UFORoboGrendizer the Fleedian race]]'' -represented in the series by TheHero Duke Fleed [[spoiler:and his sister Maria]]- looked completely human. On the other hand, the aspect of [[AlienInvasion The Vegans]] varies wildly. BigBad Emperor Vega seemed a hairy, pointy-eared, pig-nosed monster, but his daughter Rubina mostly seemed human. Other humanoid alien races in this universe range of monster-like to human-looking but with unusual hair, skin or/and eyes colour (like secondary character Menao).
* The Buff Clan in ''Anime/SpaceRunawayIdeon'' look identical to humans, with the exception of them lacking pupils. They also possess the honor code of the samurai, call their warriors samurai (though the actual humans don't), and even call their home planet Earth. If it weren't for the fact that they were an isolated race before meeting the people of Logo Dau, you'd swear that they were human!
* The aliens who inhabit the world of ''{{Simoun}}'' all appear to be human females, but are actually quite different. For one thing, they are neuter until age 17, when they become either male or female.
* The natives of ''TheTwelveKingdoms'' seem almost indistinguishable from humans of Earth stock, but in fact have a [[BizarreAlienBiology bizarre life cycle]] that includes [[spoiler: being born from large fruit that grows on special trees.]]
* Barring their monkey-esque tails (which can be permanently removed), Saiyans from ''Manga/DragonBall Z'' look exactly like humans, and can even [[HalfHumanHybrid interbreed with them with ease]]. Of course, the "Earth" of ''Dragonball'' is also inhabited by five foot tall talking foxes, dogs, cats, pigs, sea turtles... and [[UnusuallyUninterestingSight nobody ever thinks any of it is strange]].
** Also, [[QuirkyMiniBossSquad Ginyu Force]] member Recoome, who looks almost exactly like a human, unlike the rest of his team. A filler arc also had some that were fleeing from a world attacked by Frieza.
** Some of Freeza's [[{{Mook}} mooks]] look human, as well.
* Similar to the Saiyans above, Lala's race from ''Manga/ToLoveRu'' are indistinguishable from humans apart from their [[FantasticArousal tails]]. In a similar vein, there is Ren/Run, whose only difference from humans is [[SharingABody their]] [[InvoluntaryShapeshifting uncontrolled]] [[GenderBender Gender Bending]]. There are other examples of Human Aliens, but it is shown that there also exist RubberForeheadAliens and PlantAliens, so at least the universe has some variety.
* The S and Stars seasons of ''Anime/SailorMoon'' brought '''so''' many Human Aliens (or at least aliens that were ''originally'' human in appearance) from across the galaxy [[TokyoIsTheCenterOfTheUniverse to Tokyo]] that one could wonder if non-humanoid intelligent lifeforms really existed at all! Even the [[TalkingAnimal talking cats]] Luna and Artemis, who were aliens from the planet Mau in the [[Manga/SailorMoon manga]], could assume human forms. (Rei's crows Phobos and Deimos were also revealed to be aliens who could take human form in the manga.) The {{Filler Villain}}s Eiru and An from the start of the second season were also aliens who could assume human form, though the villains from the first season and the rest of the second season were originally from Earth.
** The Moon Kingdom inhabitants and the Senshi of the past also count, since they're technically not from Earth. This also means [[spoiler:Queen Nehelenia/Zirconia]], the BigBad from [=SuperS=], would count, even though the rest of her minions are either from Earth originally (animals given human form, some girls from the rainforest given powers) or are dream-monsters (the Lemures).
* The Arume in ''BlueDrop'' are human in every way, although their whole race [[OneGenderRace consists of females only]], leading to [[GirlsLove certain kinds of behavior]].
* ''Anime/NeonGenesisEvangelion'' has a complex and bizarre subversion of trope, tied in to the origins of Angels and [[spoiler: humanity, who are collectively the 18th Angel.]]
* The Plants in ''{{Trigun}}'' look exactly like humans, all to various degrees. The ones used as power look semi-humanoid with wings and other assorted appendages, while Vash and Knives can easily pass for human. This is because plants were made by humans.
** In the manga however they are [[spoiler:beings from another dimension with different laws of physics]] which is why they can generate power from seemingly nowhere. In their default state they also look something like a [[spoiler:human glued to a bunch of baby corpses, tumors, and angel wings.]]
* The Juraians in ''TenchiMuyo'' not only look human but have Japanese-sounding names. According to Ayeka's computer in the first episode of the OVA Earth is a 'colony world' seemingly suggesting that humans are actually transplanted Juraians. Unfortunately the matter is never explored beyond that one throwaway comment.
** Really, barring their [[AnimeHair hair]] and eye colors, all six members of Tenchi's UnwantedHarem can easily pass for human.
* The Nazi-inspired Gamilons from ''SpaceBattleshipYamato / StarBlazers'' began as looking identical to humans in every sense of the word. However, the creators of the show retconned their design a few episodes into the show and gave them blue skin, blonde hair and black eyes. Why? Probably to distinguish them easily from the human cast.
** This is further developed when it's discovered that the Gamilons [[spoiler:need radiation to survive, like how a human needs oxygen to breathe]].
** When the crew captures its first Gamilon prisoner and sees what their opponents look like, this is a huge shock for them, as they'd pictured the Gamilons as monsters. It plays into the theme of the episode, as well, as Wildstar / Kodai must put aside his overwhelming hatred of the aliens who killed his family to see this prisoner as a ''[[WhatMeasureIsANonHuman person]]'' who should be treated decently.
*** This scene is virtually repeated in the second season, when the capture of a Comet Empire POW proves that ''they'' are human aliens as well. This time, Wildstar [[CharacterDevelopment is the level-headed one,]] and it's [[HotBlooded Sgt. Knox]] who has to learn restraint.
* Lum and her family in ''UruseiYatsura'' look almost exactly like humans, only with two small horns and [[YouGottaHaveBlueHair green hair.]] However the series does feature other aliens in all shapes and sizes.
* The Time-Space Administration Bureau in ''MagicalGirlLyricalNanoha'' covers multiple [[AnotherDimension worlds]] but are all apparently human. One character comments on how somebody in her family history was from Earth when they were discussing "[[InsignificantLittleBluePlanet Unadministrated World #97]]".
* In ''HoushinEngi'', Taikoubou (later known as [[spoiler: Fukki]]) is later revealed to be one of the [[spoiler:"First Humans", which are actually an ancient race of aliens]], although he looks exactly like a human.
** Somewhat justified, in that [[spoiler:the "First Humans" actually merged with the planet and indirectly influenced the course of nature and evolution. So technically, humans look like THEM.]]
* The [[OneGenderRace all-female]] Alpha Cygnans in ''ProjectAKo''.
* While not aliens, the main characters of ''WolfsRain'' spend a lot of time looking human, mainly as a form of camouflage, as they're supposed to be extinct.
* ''MahouSenseiNegima'' has an interesting take on this, in that [[spoiler:the Magic World is in AnotherDimension]], that happens to be layered on top of Mars. Meaning that anyone from the [[spoiler:magic world]] is technically an alien.
* The Mu from ''Anime/RahXephon'' are entirely indistinguishable from humans save for their [[AlienBlood blue blood]]. Then there are the HalfHumanHybrids such as [[spoiler:Ayato and Hiroko]] whose Mu-phase has yet to be activated, making them appear human in every way [[spoiler:[[TomatoInTheMirror even to themselves]]]].
** Background material indicates that [[spoiler:the Mu evolved on Earth alongside humanity, so it's possible that they aren't a different species at all, but merely another race of humanity... which would turn this example into a Subversion.]]
* ''BakuganBattleBrawlers'' New Vestroia introduces an extra-dimensional race known as the Vestals. There's not much difference between humans and Vestals, aside from their eyes. Human eyes have distinct, black pupils, while the Vestal pupil is just a darker shade than their iris. Given this style of pupil can be the norm for humans in other shows, one might not notice the difference immediately.
* The aliens from ''Niea7'' are human for all practical purposes, save for the shape of their ears and conspicuous antennae (for most of them) on top of their heads. Chada is somewhat of an exception, since he is plain ... weird.
* [[spoiler:Yuki, Ryoko and Kimidori]] from ''LightNovel/HaruhiSuzumiya''.
** Those are the [[spoiler:Humanoid Interfaces]] created by the actual [[spoiler:StarfishAliens who are so alien that they don't even seem to have physical forms]]. Technically [[spoiler:Yuki]] and the others are [[ArtificialHuman gynoids]], and not aliens themselves.
*** [[WildMassGuessing Or a smaller part of the]] [[spoiler:[[StarfishAliens DITE]]]] [[WildMassGuessing in human form, under orders from superiors, which would put this trope in effect.]] And either way, Kyon seems content calling [[spoiler:Yuki]] an alien, mainly because of [[spoiler:her]] superiors.
* The Altirrans in ''BirdyTheMighty'', including the title character herself, look pretty much human and most pretty much are. That said though a few of them, again including Birdy, have super powers thanks to various [[spoiler:SuperSoldier projects, including SuperSerum projects and [[ArtificialHuman bio-engineering super soldiers]]]], the latter involving Birdy herself.
** Though there are apparently enough differences that Birdy in the remake manga had to warn Tsutomu to avoid the hospital lest abnormalities be detected.
* The Coralians in ''EurekaSeven'' are born with various shapes and sizes for their forms, including human Coralians like Sakuya, [[spoiler: Eureka and Gonzy.]]
** Justified in that they were [[spoiler:created to look that way.]]
* Haruko Haruhara from ''Anime/{{FLCL}}''... maybe. She claims to be a 19-year-old space patrol officer, but is actually a galactic criminal out to find the Pirate King Atomsk. Its kinda hard to be sure of anything Haruko tells anybody. Other than pink hair and yellow eyes, Haruko is entirely humanoid. Also she fights with a Rickenbacker guitar, uses a house cat as a walkie-talkie, and has a flying Vespa.
** She can change her voice and probably appearance at will, as seen in episodes 1 and 5, which puts her in the AFormYouAreComfortableWith category. Which would also explain what happens to her face when she's angry.
* In ''WorldOfNarue'', Narue is half-alien half-human, but her father, sister, and all other members of her species look completely human. They also come from planet Japan, which also appears to have a history very similar to the Japan we know, so go figure. The manga series [[{{Deconstruction}} gradually explores the concept further]], and it turns into one of the big mysteries of the setting why all the known alien races are indistinguishable from Earth humans. Two major interstellar political bodies are ready to go to ''war'' over which answer they believe in. It's one of several soft sci-fi tropes the series tackles.
* In ''LightNovel/AsobiNiIkuYo'', not only do the Catians look exactly like humans except for the [[{{Catgirl}} cat ears and tail,]] they even called THEIR planet "Earth" until they decided to make contact with us, then re-named it to Catia for our convenience. This seriously ticks off Beautiful Contact, a group of hardcore sci-fi fans who insist that humanity's FirstContact with an alien species should be with a race that looks more dignified and unearthly.
** There's also an antagonistic race of dog-eared humanoid Dogisians.
* Mizuho Kazami and her family from ''PleaseTeacher'' look like humans with weird HairColors. She is herself a HalfHumanHybrid, but her mother isn't.
** Not surprisingly, the same trope is in effect for Ichika Takatsuki in the "remake," ''AnoNatsuDeMatteru''.
* The Yato from ''Manga/{{Gintama}}'' appear very human, although they do have super strength and are weak to the sun. Even their coloring isn't unnatural -- Kagura and Kamui's orange hair and blue eyes would be uncommon in Japan, but have been seen elsewhere. Other Yato characters are shown with even plainer coloring.
* The aliens of PleaseSaveMyEarth are only the size of a human thumb, but look exactly like humans.
* ''Anime/GaoGaiGar'' has [[TagalongKid Mamoru Amami]].
* ''{{Sekirei}}'' has the OneHundredAndEight beings that give the series its name, who are essentially a cross between a humanoid {{Mon}} and a MagicalGirlfriend. The vast majority are [[BuxomIsBetter beautiful]] women and cute girls, with a handful of extremely rare {{Bishonen}} on the side. They physically resemble humans, but possess various super-powers and require a human partner (an Ashikabi) to unlock their full power. A major source of their power is ThePowerOfLove, so the partnership with an Ashikabi is almost always InterspeciesRomance.
* ''Manga/GingaKikoutaiMajesticPrince'' depicts the antagonistic alien species known as the Wulgaru (aka "the Ulgars"), and numerous instances are pointed out to the characters that, despite their notable human appearances, they are aliens. The reason for this is the fact that [[spoiler: the species had been in decline for thousands of years, and as a means to preserve itself, spread its genetic data throughout the universe to cultivate new life, only to harvest it later. Humanity is one of these creations.]]
[[/folder]]

[[folder:Comic Books]]
* {{Superman}}, {{Supergirl}}, and all other Kryptonians are outwardly indistinguishable from humans, despite obvious biological differences. Exactly ''how'' close or distant humans and Kryptonians are can vary [[DependingOnTheWriter depending on the work]]:
** According to some [[TheSilverAgeOfComicBooks Silver Age]] stories, Kryptonians were descendants of humans plucked from Earth by a more technologically advanced race. Some PostCrisis stories imply this as well.
*** One Superman/Flash story has the duo facing a mysterious alien race that apparently seeded both Earth and Krypton with life, at around the same time, serving as a possible explanation for this trope.
*** It is mentioned that Jor-El chooses Earth ''because'' humans looks exactly like Kryptonians, so Kal-El could live among them without detection.
** [[LampshadeHanging Lampshaded]] in an issue of ''Comicbook/{{Starman}}'' where Jack Knight's journeys through space and time land him on Krypton before its destruction. He is promptly arrested by the authorities, who suspect him of being a member of a Kryptonian rebel group. When Jack tries to argue that he's an alien visitor from planet Earth, his interrogator refuses to believe him, pointing out that he looks no different from any Kryptonian. Jack wonders whether God was feeling unoriginal.
** Other stories suggested that the human and Kryptonian species actually were directly related.
** Krypton dodges the Caucasian trap via "Vathlo Island", home to "a highly developed black race" of Kryptonians, first mentioned in 1971.
* There's a very strong tendency for aliens in TheDCU to look exactly like humans:
** Most inhabitants of New Genesis and Apokolips resemble humans. In one issue where Doomsday arrives on Apokolips, the aliens crewing the ship that brings him there look human.
** In ''ComicBook/{{Legion Of Super-Heroes}}'', most of the alien races are perfectly humanoid in appearance, although they possess various additional abilities. [[PostCrisis Post-Crisis]], this was {{handwave}}d by having them be descendants of humans who were given superpowers in alien experiments (this explanation was later {{retconned}} out of existence by the 2010 "New Krypton" storyline, which tells us they were, in fact, alien races to begin with.)
** PostCrisis, it was established that [[ComicBook/{{Legion of Super-Heroes}} Mon-El's]] people, the Daxamites, are descended from Kryptonians, explaining the similarity of both races.
** Natives of Rann seem to be entirely indistinguishable from humans. Indeed, human hero AdamStrange had a child with his Rannian wife Alanna.
** Likewise, [[{{Hawkman}} Thanagarians]] and humans look exactly alike, though in [[TheDCAU the DC Animated Universe]] Thanagarians like Hawkgirl are significantly stronger and tougher than humans.
** ''BlackestNight'' revealed that Earth was really the place where life began, which might help explain all the humanoid life in the galaxy.
** The planet Bellatrix from the ''ComicBook/GreenLantern'' series has a very human-looking population, but with a refreshing amount of diversity. One of the planet's two Lanterns, Zale, fits this trope, looking like a human of African descent.
** Notably, [[TeenTitans Tamaranians]] are indistinguishible from humans, save the solid green eyes and spray-tan color skin, yet are specifically stated to taxonomically be ''felines'' rather than apes.
* The MarvelUniverse also has a number of examples:
** The Kree are divided into two races: the pink Kree, who look just like Caucasian humans, and the blue Kree, who look just like humans, save for their [[RubberForeheadAliens blue skin]].
** The Shiar, who are basically humans with avian forefathers, birdlike physiology (yet NonMammalMammaries) and enhanced physical abilities.
** [[ComicBook/TheMightyThor Asgardians]], which are basically much stronger and longer living humans with access to mystical powers.
** Karolina Dean of ''Comicbook/{{Runaways}}'' looks exactly like a normal human as long as she wears a bracelet made from a special material that dampens her powers. When she takes the bracelet off, she looks more like a [[EverythingsBetterWithRainbows human-shaped rainbow]] . It turns out that her parents come from the planet Majesdane.
** The title character from OmegaTheUnknown, who was [[CreatingLife created]] by another alien race to be the perfect {{Ubermensch}}.
** The Galadorians of ''RomSpaceknight.''
** The people of Homeworld in ''Franchise/{{Micronauts}}.'' It was eventually explained that they and the RubberForeheadAliens of the Microverse are descended from humans from [[TimeTravel the future]].
** Nebulans from ''ComicBook/TheTransformers''.
** This is all explained by the fact that the Celestials based all dominant life forms on the same template
* In a similar manner to Superman, the Viltrumites of ''ComicBook/{{Invincible}}'', of whom main character Mark is a [[HalfHumanHybrid human hybrid]], are basically humans with superpowers, and, if they're male, mustaches. All of them. And that's it. It's later revealed that Viltrumites are almost 100% biologically identical to humans. [[spoiler:Facing extinction, the surviving Viltrumites relocate to Earth to breed.]]
* The Wildstorm Comics [[TheVerse 'Verse]] has Kherubim, super-powered humanlike [[{{Immortality}} immortals]] who can even interbreed with homo sapiens. It's eventually [[{{Retcon}} revealed]] that this is because Earth and other planets were [[spoiler:seeded with devices designed to spread the Kherubim genome]] across the universe in a form of bloodless conquest. Not that they were averse to the bloody kind on occasion either, being [[ProudWarriorRaceGuy a Warrior Race]].
* The many worlds of the Creator/CrossGen universe seem quite prone to humanity as a dominant population. Possibly explained by Geromi in ''Crux'', who mentions a mass exodus from Earth at some point that led to many other worlds being colonized, and that nobody's a true human any more. Discussed in the world-hopping storylines of ''Sigil'' and ''Mystic'', when Sam and Giselle encounter humans on a variety of strange worlds (in fact, it initially takes Giselle a while to realize she's not on Ciress any more). It is worth noting that [[AGodAmI Solusandra]] apparently created many of the worlds depicted and populated them according to whatever theme had struck her fancy at the time. Whether she actually created the human inhabitants as well or simply transported them from elsewhere in the diaspora is unstated.
* The title character from ''ComicBook/{{Superlopez}}''.
[[/folder]]

[[folder: Fan Fic]]
* In ''Fanfic/KeepersOfTheElements'', everyone from the magical planets Alma, Spectra, Erendor, Wispera and Nadir resemble humans, with few exceptions.
* The Angels, Jews, and Muslims in the ''FanFic/SonicXDarkChaos'' universe. Humanity was originally descended from them, and they look very similar to humans with only a few minor quirks.
** Ethnic Angels closely resemble Tolkien [[TheFairFolk elves]]. They are often tall and fair.
** Jews are short, dark-skinned tribal people with [[BadassBeard Badass Beards]]. Jesus, although he's the leader of the whole Federation, is one of these.
** Male Muslims are generally quite similar to Jews. Female Muslims are always completely covered up, and [[BodyHorror for good reason]].
[[/folder]]

[[folder:Film]]
* All the alien races in ''Franchise/TheChroniclesOfRiddick'' series. This gives the superficial illusion of AbsentAliens, but there are a few here and there revealed to be aliens. Such as the air elemental, who looks like [[strike:a normal old lady]] Dame JudiDench, but can turn into mist as she chooses. And there's the protagonist, Riddick, who's Furyan.
** Although neither are positively identified as aliens; the Elementals may simply be humans who have developed certain skills or been modified in some unexplained, apparently supernatural way - this apparently being possible in the Riddick Universe, judging by the Lord Marshal - and it is never explicitly stated whether the Furyans are an alien race, or merely a particular human population. In the Alan Dean Foster novelization Furyans are simply humans from a world of high gravity and Riddick is the last one, explaining his strength and speed on worlds with lower gravity.
* Asgardians in the ''Franchise/MarvelCinematicUniverse'' are physically indistinguishable from humans, but you can usually tell when you're [[LargeHam talking to one]]. Their main difference is that Asgardians are ''far more'' durable than humans, except when Thor was de-powered. The ''other'' races, like the Jotuns and Chitauri, fall into HumanoidAliens.
** There is the implication is that there are other humans beside those on Earth: The Other mentions that the Tesseract was "on ''a'' human world," not "''the'' human world. "
* Practically all alien races in the ''Franchise/{{Godzilla}}'' movies. (Although sometimes this is [[MobileSuitHuman just a disguise]] for [[Film/GodzillaVsMechagodzilla space gorillas]] or [[Film/GodzillaVsGigan cockroaches]].)
* Thomas Jerome Newton in ''Film/TheManWhoFellToEarth'' is actually a RubberForeheadAlien, but appears human (as human as David Bowie is capable of looking, at least) throughout most of the film through the use of contact lenses and stage makeup, as well as a few prosthetics for other parts of his body. Without his cosmetics, his bright golden skin and eyes with vertical, ovular pupils would give him away. Biologically his people are similar to humans, but among other things have longer life spans (Newton remains the same age while other characters in the movie go from college age to their late 50s) and are extremely sensitive to X-rays (even more so in the source novel, in which they prove [[spoiler: blinding]]).
* The squid-like Thermians in ''Film/GalaxyQuest'' use [[AppliedPhlebotinum appearance generators]] to look human. Somewhat justified: they based their entire society and technology on a human TV show, and they were trying to fit in with their human guests. Since they have no concept of deception, it isn't meant to let them pass for human or even to make the humans ease into the whole alien thing; it's just their version of {{Cosplay}}.
** Also, the Thermians built their ''Protector'' to look and control exactly like the one they saw on TV... which left them with a machine wholly incapable of being controlled by their actual bodies. They need human-shaped hands to use the ship!
* ''Franchise/StarWars,'' of course, features Human Aliens alongside SerkisFolk. There's [[ALongTimeAgoInAGalaxyFarFarAway no sign of Earth]], and what connections or differences exist between the totally-human-looking races of different worlds remains unknown. (One must wonder if there are other planets with, say, Wookiees that are completely unrelated to the ones of Chewie's homeworld of Kashyyk...)
** Most sources which dwell on the subject imply that Coruscant is the human homeworld, but no one knows for sure. The other humans are the result of sleeper ships launched before the founding of the Galactic Republic or of {{Precursors}} moving them around as slaves. Some were separated long enough ago and/or ended up in sufficiently divergent environments that they evolved into what are known as "Near-Humans", basically different enough that they'd be considered new subspecies, but still close enough to interbreed with "normal" humans. After the founding of the Republic (most of whose members were the result of the sleeper ships) widespread colonization ensued using the hyperdrive.
** ''KnightsOfTheOldRepublic'' implies that the human homeworld was actually Tatooine. The {{original|man}}s were the ancestors of the Sand People as well, who abandoned technology after a (technically) successful rebellion against the Rakatan that also led to the world being turned into a desert by orbital bombardment.
*** ''VideoGame/KnightsOfTheOldRepublic'' rather implies that the Tusken might be another human or near-human race.
** When C-3PO introduces himself, he always adds, "human-cyborg relations". It seems they are human after all. Then again, he's [[FridgeLogic not a cyborg]], and neither Darth Vader nor General Grievous, who really are cyborgs, need an interpreter to speak with humans.
* ''Film/TheLostSkeletonOfCadavra'' used this trope with the "Marvans" as part of an AffectionateParody of low-budget sci-fi horror movies from the 50s.
-->'''Lattis:''' It's interesting how different people from different planets differ.
* ''RaceToWitchMountain''. The aliens look ''exactly'' like humans... but then there's the superpowers. When Dwayne Johnson's character [[InvokedTrope points this out]], they [[{{Handwave}} respond]] with "What's an alien ''supposed'' to look like?" He responds with his idea that they were supposed to resemble little green men.
* [[Film/TheRockyHorrorPictureShow Dr. Frank N Furter, Riff Raff, Magenta, and the other Transylvanians]] look like normal (well, normal except for their sexual practices) human beings. Considering that the film is an AffectionateParody of old B-Movie science fiction films, it's no surprise.
* It's strongly implied in ''Film/{{Outlander}}'' that Kainan's people are related to humans, as his computer describes Earth as an "abandoned seed colony".
* Most of the aliens in ''Film/TeenagersFromOuterSpace'' look human.
* The three aliens in ''EarthGirlsAreEasy'' look human.. after all their fur has been shaved off and their [[AmazingTechnicolorPopulation primary-colored skins]] have been dyed different shades. (The leader of the aliens is played by a swarthy Jewish-American actor, while the other two are a light-skinned African-American and a pale Anglo-Canadian.)
* In ''Film/Plan9FromOuterSpace'', Eros, Tanna, and the Ruler of the Galaxy all look perfectly human.
* The immortals from Zeist in ''Film/HighlanderIITheQuickening''.
* Shep Ramsay in ''Film/SuburbanCommando''
* [[spoiler: Ella]] was an alien who took on human form in order to blend in among humans in ''Film/CowboysAndAliens''.
* Common when aliens turn up in MaskedLuchador films such as ''Film/SantoContraLaInvasionDeLosMarcianos'' (Santo vs. The Martian Invasion, 1966). Typically, the alien invaders are fair-skinned and platinum blond haired, not unlike [[http://en.wikipedia.org/wiki/Nordic_aliens the "Nordic Aliens"/"Space Brothers"]] of UFO mythology.
* ''Leprechaun4InSpace'' features an alien princess who teams up with the Leprechaun [[HighHeelFaceTurn (only to reveal at the end she's been secretly working against him the whole time)]]. She looks exactly like the sexy blonde human woman who's portraying her; her only real difference from us is that she has green blood.
* Kryptonians in ''Film/ManOfSteel'', as always, look perfectly human despite their alien biology.
* He-Man, Man-at-Arms, Teela, Blade and Evil-Lyn in ''Film/MastersOfTheUniverse''.
* Most of the aliens in the Kingdom of Mongo in ''Film/FlashGordon''.
* Centauri puts on a human face, the Zando-Zan assassins take on human form, and the Rylans look basically human in ''TheLastStarfighter''.
* The alien visitors to Earth in ''WhatPlanetAreYouFrom'' look completely human. Then again, they can [[RuleOfFunny shoot rays of light out of their nostrils]], so obviously they aren't.
* ''Film/QueenOfOuterSpace''. When our heroes realise they've crashlanded on Venus, they speculate on what form of intelligent life might inhabit it. Insectoid beings? LittleGreenMen with eyes on stalks? They're later captured by a [[LadyLand society consisting entirely of hot babes]] in [[SpaceClothes miniskirts and high heels]].

[[folder:Literature]]
* RobertRankin shamelessly {{lampshade}}s this in one of his stories (''Armageddon, the Musical'') where it is advanced as proof that there is a {{God}} who designs dominant species in his own image. "As any ScienceFiction fan knows, the basic human shape, Head at the top, two feet at the bottom, wedding tackle about halfway down, is the standard for intelligent life the universe over. They often speak good English with a noticeable American accent, too. Facts that should serve up friend Atheist with a workload of eggs, faces for the use of."
* In one ''Literature/{{Discworld}}'' book (though it was referring to gods, the spirit's the same), it's mentioned that if you ask someone to come up with an alien-looking being, it would basically be a man in an animal mask.
* OlderThanTelevision: Creator/EdgarRiceBurroughs did this all over the place starting back in 1912 with ''[[http://en.wikipedia.org/wiki/A_Princess_of_Mars A Princess of Mars]]''. Everybody on Mars except the Green men looked human, but [[GreenSkinnedSpaceBabe hotter]], and have much longer lifespans. The earth born hero [[JohnCarterOfMars John Carter]] and his Martian Princess wife have two kids, despite massive [[BizarreAlienBiology biological differences]] including Martians being oviparous. This doesn't even begin to cover some of the [[BizarreAlienBiology wild biology]] that shows up in ''Literature/TheLandThatTimeForgot'' stories.
** The most sensible explanation for this is that John Carter ''is'' an amnesiac Martian. He's had a very long life with no signs of aging, aside from being interfertile with the native, '''egg-laying''' Martians...
* The Takisians of the ''WildCards'' series. In fact, that's what leads to the entire plot of the series; the Takisians note how biologically similar they are to humans, believe they must be the descendants of a "lost colony," and drop the wild card virus on Earth to test out its purpose as a biological weapon.
* The various biological species of Literature/TheCulture are mostly human-looking, although they have various additional internal glands and bits. Given the degree of casual genetic modification in the universe though, it's anyone's guess as to whether they were all always like that.
** In ''Literature/UseOfWeapons'', Shias Engin asks Zakalwe "I know that all the outworlders aren't humanoid, but a lot are. How come?". Zakalwe replies jokingly that it is the universe's way of getting rid of alcohol.
** Some of them ''are'' human, a result of the Culture grabbing some of them to spread out across the universe.
** The essay [[http://www.vavatch.co.uk/books/banks/cultnote.htm A Few Notes on The Culture]] deliberately sidesteps the issue:
--> Now, in all the above, there are two untold stories implicit. One is the history of the Culture's formation, which was a lot less easy and more troubled than its later demeanour might lead one to expect, and the other is the story which answers the question; why were there all those so-similar humanoid species scattered around the galaxy in the first place?
-->Each story is too complicated to relate here.
* In Creator/UrsulaKLeGuin's series the Hainish Cycle, this is because all the humanoid races are from planets colonized by the titular Hainish. Including Earth humans. Despite a common ancestry, they don't all look like us. The Cetians are hairier, for example, and the Athsheans are green (fairy green, not Martian green) and diminutive.
* In Creator/JamesPatterson's ''The Dangerous Days of Daniel X'', the aliens on Daniel's home world, Alpar Nok, look exactly like humans. The planet even [[AllPlanetsAreEarthLike looks like Earth]].
* In the ''Literature/PerryRhodan'' universe, the ancestors of the most prominent 'human alien' races of our galaxy actually came from Earth. (Extra irony points for one of those species later coming back and, quite unaware, [[AncientAstronauts claiming 'Larsaf III' as a colony of their own]] for a brief time.) Humanoid life in general seems to have some common ancestors in the distant cosmic past, and can also be partially justified by the fact that SufficientlyAdvancedAliens have been known to meddle in the evolution business as well.
* {{Justified|Trope}} in Creator/CSLewis's Literature/SpaceTrilogy, whose premise is that Literature/TheBible is true: since [[{{Jesus}} the Son of God]] became a human, any intelligent beings created after Jesus' birth will also have human form.
** Jadis in the {{Narnia}} series may also qualify, as {{God}} in this series has created nearly identical animals on other worlds. This also results in such things as Bear Aliens and Mouse Aliens. On the other hand, Jadis may be descended from TransplantedHumans, like the Narnians.
*** The beavers in ''The Lion, the Witch, and the Wardrobe'' claim she was descended from Lilith, which just raises further questions. Of course, they aren't exactly experts on Jewish apocrypha.
*** Specifically, she is claimed to be descended from the Djinn on one side of her family, and the Giants on the other, and to have no human blood at all. One of the themes in the books is that being that look like humans but aren't are, invariably, wrong in ways that make them inimical to humans. This probably is not her true heritage so much as {{malicious slander}} but Jadis claims to be an Earth human, which is equally untrue.
* The Literature/NoonUniverse novels of the Creator/StrugatskyBrothers feature a lot of PlanetOfHats Human Aliens civilizations, though their cultural, technological and historical development is rarely 100 % identical to that of the Terrans. [[PlayingWithATrope Among the most inventive examples]] are the people of the planet Saraksh, whose entire philosophical and religious system has been heavily influenced by the immense optical refraction phenomenon present in the atmosphere of their homeworld. From the surface it looks like the horizon is above the observer, which makes the Sarakshans think that they actually live inside a hollow cave in an endless piece of rock, rather than on a round planet floating in space. They call all who claim otherwise [[PardonMyKlingon "Massaraksh"]] ("of the world inside-out"), a term which is also an UnusualEuphemism for "insane".
** Then there are the Leoniders, who are essentially a whole race of SpaceAmish, and the people from the unnamed planet Arkanar is located on, who are locked in a MedievalStasis by their damaged culture rejecting science.
** The Noon-verse is also a [[SubvertedTrope subversion]], since it features several IntelligentGerbil (e.g. Tagorians, Golovans) and StarfishAlien races (e.g. [[{{Precursors}} Wanderers]], Ark Megaforms).
* ''Literature/EnchantressFromTheStars'' has all the alien civilizations be different types of humans to make it ambiguous which civilization is Earth. The Torisians of its sequel, ''Literature/TheFarSideOfEvil'', are also pretty human.
* [[JustifiedTrope Justified]] in Creator/SergeyLukyanenko's ''Literature/ALordFromPlanetEarth'' trilogy, where all races in the Milky Way (except [[spoiler:humans]]) have been [[{{Panspermia}} seeded]] by a mysterious [[{{Precursors}} precursor]] race. Played straight with Human Aliens from a faraway galaxy.
* Thomas in ''Literature/TheManWhoFellToEarth''.
* In Sergey Volnov's ''Army of the Sun'' trilogy, there are three alien races who are dead ringers for three of the major human "sub-races" (the term used in the books): whites, blacks, and Asians. Nobody knows why that is the case, although there are plenty of other humanoid races. The leading theory is that they have been transplanted to other planets from Earth by {{Precursors}}. This theory is partially supported by several ancient records of the "Asian" race that look eerily similar to Ancient Chinese. To top it off, the name of their legendary ancient leader is very similar to "Genghis Khan". In any case, during the centuries of galactic domination of the [[TheEmpire EarthStella Empire]], these three races were shown preferential treatment due to their, at least external, similarity to humans. After the aliens rebelled (justified, as Imperial humans were [[HumansAreTheRealMonsters bastards]]), they killed off many humans and enslaved many others. Those who survived and were not enslaved are still treated as second-class citizens (if that). As such, most traveling humans tend to pass themselves off as members of one of these human-like races, as aliens have no beef with them.
* This is the whole point of Zenna Henderson's Literature/ThePeople. They may be from another world and have paranormal abilities, but they look exactly like us. (In one story, "Deluge", there's a hint that they may have changed some to match Earth's environment.)
* The Elyins and the Kin in Geary Gravel's 1984 novel ''The Alchemists''.
* Parodied in ''Literature/TheStarDiaries'' by Creator/StanislawLem, where a group of StarfishAliens living on an extremely hot planet discuss a possibility of an intelligent species living in a lower temperature; the oldest one explains that the existence of such creatures is impossible, and any other sapient species must be exactly like them. While Lem used the trope in comedic works, he criticized its use in serious ones.
* The people of Ginen in ''Literature/TheShadowSpeaker'' look like black Africans.
* In Alan Dean Foster's HumanxCommonwealth novels, we meet the Pitar, a race that by chance resembles beautiful, perfect humans (albeit with some slightly odd hair and eye colors in the mix).
* Played almost completely straight in MikhailAkhmanov's ''ArrivalsFromTheDark'' series. While there are some StarfishAliens and LizardFolk, most races are of humanoid nature and some are even capable of interbreeding with humans (although this is a rare case). Several are sexually compatible but are not capable of producing offspring together. There is also a race of SpaceElves who are specifically referred to as "pseudo-humanoids", as they have 4 sexes and reproduce telepathically. It should be noted that the LizardFolk still have a basically humanoid shape with the only addition being a tail. However, they are hermaphrodites. The ''Trevelyan's Mission'' series, taking place in the same 'verse but much later, introduces other humanoid races, mentioning hundreds of others that have been found in-between the series, most of which are on primitive development levels.
* In ''Literature/TheClanChronicles'' by Creator/JulieECzerneda, the only way you'd know a mated adult female Clan from a human is because [[ExpressiveHair their hair has a mind of its own]]. Men and unmated women look exactly like humans.
* In {{Literature/Adaptation}} by Malinda Lo, [[spoiler: the Imria look exactly like humans but have biological differences such as {{HealingFactor the ability to heal quickly.}}]]
* In WenSpencer's Literature/UkiahOregon series most of the Ontongard and Pack are indistinguishable from humans unless they're [[AlienBlood injured]], because they are a virus that took over a human, and they look like their host.
[[/folder]]

[[folder:Live Action TV]]
* ''BattlestarGalacticaReimagined'', convergent evolution is TurnedUpToEleven, even {{Aliens Speaking English|linguistically}}. [[spoiler:and colonials are miraculously capable of interbreeding with primitive humans native to Earth.]]
* In ''{{Smallville}}'', Clark and any kryptonian, of course. MartianManhunter also uses a completely human form for 99.9% of the time. All the PhantomZone escapees are aliens, and some are excused because they are possessing humans, but the rest still look mightily like humans. In fact, throughout the ten seasons of ''Smallville'', there has not been a ''single'' alien without a human form.
* ''Series/DoctorWho'' did this more times than can be counted. The most famous examples are, of course, the Doctor himself and the other Time Lords. Their most noticeable physiological differences (two hearts, 60-degree Fahrenheit body temperature, a far more complex brain structure, a respiratory bypass system, "symbiotic nuclei" in their cellular structure, and whatever organs or systems are responsible for their ability to regenerate) were effectively invisible to the television viewer.
** In fact, right at the very beginning, the Doctor was so human he was even AmbiguouslyHuman. He tells Ian and Barbara that he is "not of this race", but refers to himself as a 'human being' in "The Sensorites" and "The Savages". "The Power of the Daleks" is the first story that really explores him being non-human, such as dealing with the fallout of his recent regeneration and revealing things like his absurdly long lifespan.
** The Fourth Doctor tells Sarah Jane at one point when she's wondering at this that although he looks human to her, other species can quite easily tell them on sight as two separate species.
** The ExpandedUniverse did a LampshadeHanging by having a racist founder of Time Lord society, who thought that the Time Lord form was supreme to any other, go around the universe and infect species with a virus that would cause them to evolve into humanoid forms.
** Earlier, the ExpandedUniverse lore had come up with a completely different LampshadeHanging, also involving the Time Lords. The Time Lords evolved first out of all sentient species. Therefore, the [[http://en.wikipedia.org/wiki/Morphic_field morphic resonance]] of Time Lord-ness propagated throughout the universe.
** Yet another [[LampshadeHanging lampshade was hung]] in the Easter 2009 special ''Planet of the Dead''. A similar conversation between Amy and the Doctor was repeated in "The Beast Below", the following year.
--->'''Christina''': You look human.
--->'''Doctor''': You look Time Lord.
*** [[http://www.youtube.com/watch?v=EKQNZweeAi8 A DVD-exclusive scene]] bridging "The Eleventh Hour" and "The Beast Below" lampshades it further: Amy hypothesizes that the Doctor's [[MobileSuitHuman a tiny little slug in a human suit]]. The Doctor is not amused.
*** A similar situation does appear in the Slitheen two-parter "Aliens of London" / "World War III" where Mickey asks Rose how she doesn't know the Doctor isn't just wearing a human suit like the Slitheen.
** This comes up in the classic series as well, most notably in 1973's ''Carnival of Monsters'', where a travelling Lurman showman named Vorg remarks upon the strong resemblance between his species and the human race (known to him as Tellurians):
--->'''Vorg''': These creatures are Tellurians, a species discovered in a distant galaxy. Scientists have been amazed at the remarkable similarity between these little chaps and our own dominant lifeform.
--->'''Orum''': The resemblance is unpleasant.
--->'''Vorg''': These are the only Tellurians in captivity. Some scientists think that their discovery refutes Valdek's theory that life in the universe is infinitely variable.
** Thals and Kaleds look like humans. "The Stolen Earth" reveals that they have fewer ribs than humans and BizarreAlienBiology, though.
** According to the audio drama ''I, Davros: Corruption'', Kaleds and Thals were separate species who both evolved (on the same planet, obviously) to a humanoid form as that is the optimum biological form for Earth-like planet. One of the novels in the ''Franchise/DoctorWhoExpandedUniverse'' made a similar claim about all human like species which may or may not contradict the explanation given above relating to the Time Lords.
** The Fifth Doctor had quite a few non-Time Lord Human Alien companions, to the point where it gets a bit of a LampshadeHanging in ''[[Recap/DoctorWhoS19E2FourToDoomsday Four To Doomsday]]''. Tegan mentions that she's human, and their alien hosts ask if the rest of them are too. The Doctor has to correct them that, no, he's from Gallifrey, Nyssa is from Traken and Adric is from Alzarius. Turlough from Trion joins the TARDIS the following season, just to top it all off.
** In the 2007 Christmas special "Voyage of the Damned", everyone seen on board the ''Titanic'' (a starship moulded into a replica of the 1912 ship) apart from two cyborgs are indistinguishable from humans, yet know very little about Earth culture, even the self-proclaimed Earth expert.
*** Somewhat justified however, with the revelation that [[CorruptCorporateExecutive Max Capricorn]] chose the name ''Titanic'' on ''purpose'', betting on the people of Sto being so ignorant of Earth culture that the name wouldn't raise any alarm bells, allowing him to collect the insurance when the ship [[BlatantLies tragically crashed]]. The Earth Expert similarly admits he's a fraud and just SignedUpForTheDental.
* ''Series/StarTrekTheOriginalSeries'' had several, and it was rather strange when Spock was the only crew member who had to disguise himself on an alien planet. (It was even stranger when Kirk's BeleagueredChildhoodFriend was able to make himself dictator of an alien planet without any of the aliens noticing something odd about him.) In fact, aliens are Human Aliens more often than not, probably for budgetary reasons.
** One comment by Spock during the first season suggested that his species and many other humanoids were created by a superior race and it was part of his planet's mythology. This explanation seems to have been dropped in favor of one in which a race of ''{{Precursors}}'' seeded DNA with code to create humanoids in ''Series/StarTrekTheNextGeneration''.
** ''Series/StarTrekTheNextGeneration'' attempted to provide an explanation for the prominence of humanoid species (both Human Aliens and RubberForeheadAliens) in the universe by revealing that there was a common ancestor race that "seeded" the galaxy with its basic genetic material. They switched to exclusively using RubberForeheadAliens rather than Human Aliens after the first few seasons (excluding Guinan's people, the El-Aurians and Councelor Troi's, the Betazoids -- sort of, the Betazoids are ''very subtle'' RubberForeheadAliens (or rather, Coloured Lenses Aliens)).
** ''Series/StarTrekVoyager'' had a few Human Aliens in ''its'' first season, too, mainly wearing strange and colourful national dress.
*** Oddly this is inverted by a species encountered by Voyager that look sufficiently [[LizardFolk lizard like]] but turn out to be, while not human, from Earth!
*** Roddenberry was quite clear that budgetary reasons was the cause of TOS' many Human Aliens, and that in his view many of them (including the Klingons) weren't ''actually'' Human Aliens, the show just didn't have the budget to show their Rubber Forehead-ness. The Klingons were the only ones who actually ''did'' get redesigned into RuberForeheadAliens in later appearances, and eventually there was even an in-universe explanation for change in appearance.
*** TOS's habit of having worlds [[InexplicableCulturalTies oddly similar to a human culture]] as well as a short on-screen cameo in a book in ''Enterprise'' ended up bringing in an ''additional'' reason for all the Human and Rubber Forehead Aliens, beyond the aforementioned Precursors: evolution, both biological and sociological, runs more in parallel than what one would think from the evidence on Earth (this handily also explains all the Earth-looking fauna and flora encountered).
** An episode of ''Next Generation,'' "Code of Honor", tried to reverse the Caucasian Aliens trap by giving us a planet where the aliens all looked human, but African. The results are generally agreed to be staggeringly racist, and to have turned a mediocre episode into one of the worst of the entire franchise.
* ''Franchise/StargateVerse'':
** In ''Series/StargateSG1'' and ''Series/StargateAtlantis'', the "humans" in Pegasus and the Ori galaxy were seeded by the Ancients and Ori through genetic engineering, and are not directly descended from them, despite the use of the term "ancestors" in Pegasus. The humans on Earth presumably came about the same way. Humans were not seeded on any other Milky Way planet: the Goa'uld brought them to those worlds from Earth.
** There are a few occasions where the trope is played straight, however. Most notable are the Nox, who can only be differentiated from humans by their big, poofy hair. There's also the one-shot race from SG-1: "One False Step", who look like humans with white paint smeared all over their bodies. Finally, Aris Boch, a one-shot BountyHunter from SG-1: "Dead Man Switch", looks completely human on the outside, but has AlienBlood and something about his species, identified in the RPG as the Ilempiri, renders them immune to Goa'uld infestation. [[BlessedWithSuck The snakes wiped most of them out because of it.]]
* The four alien kids from ''{{Roswell}}'' who looked human, [[DawsonCasting but prettier]]. It's gradually established that they are actually traditional Roswell [[TheGreys greys]] in [[VoluntaryShapeshifting human form]]. The thing is, they assumed these forms before exploring outside their crashed spaceship as children. The reason they knew to do so was later {{Handwave}}d by explaining they are {{Half Human Hybrid}}s. Whew!
* On ''Series/{{Farscape}}'', several races look like humans, except for strange colored eyes or hair or (sometimes) skin. Which makes them all RubberForeheadAliens, but the Sebaceans look ''exactly'' like humans, despite having a considerably different biology. Eventually, this is explained: [[spoiler:In ''The Peacekeeper Wars'', we learn that the Sebaceans actually *are* humans, just genetically engineered to a much higher [[EvolutionaryLevels level of evolution]].]]
** Which actually makes zero sense if you apply the real world idea of evolution and realize that any race that dies an horrific death whenever it gets hotter could in no way be considered a superior version of humanity. We're not even talking about insane levels of heat here either; we're talking the kind of heat where normal humans would counter it by breaking out a refreshing glass of lemonade.
*** On the other hand, it's important to remember what the Peacekeepers were engineered ''for''. If you were designing a race of space-faring super-soldiers that likely wouldn't spend any significant time outside of a climate-controlled war ship, thermal regulation wouldn't be all that crucial. The other aspects of Sebacean engineering (greatly improved eyesight, easily delayed and managed gestation, etc.) have obvious value for the job. And who knows, maybe the heat-intolerance is just a side-effect of some more useful trait (like being able to survive sudden cryogenic freezing without severe tissue damage).
* Mork, from ''MorkAndMindy''. He was even able to have a kid with Mindy (although he was the one who laid the egg, and the kid was middle-aged Jonathan Winters.)
* ''Franchise/PowerRangers'' ''really'' abuses this trope, invoking it for more or less anyone who isn't a [[RubberForeheadAliens rubber-forehead-alien]] or a robot-ish thingy. They even stated that aliens can be human, but they never explained how the same species can exist in multiple planets.
-->'''[[Series/PowerRangersInSpace Andros]]:''' What, you think Earth is the only place humans come from?
* The five initial team members of ''Series/KaizokuSentaiGokaiger'' are space pirates who hail from various worlds, and yet are all effectively human. Their AscendedFanboy SixthRanger is a genuine human, from Earth.
* The Centauri from ''Series/BabylonFive'' look outwardly exactly like humans, except for their barely noticeable CuteLittleFangs. They also have distinctive hairstyles - the men wear their hair in fans like peacock tails and the women shave their heads - but this is a cultural difference rather than a physical one.
** However, beneath the surface they have BizarreAlienBiology - double hearts, lack of major blood vessels in the wrists, and very different genitalia (the men have six tentacles and the women have six orifices along their spines).
** This was lampshaded in the first episode, where it is revealed that, after encountering humans for the first time, the sneaky Centauri claimed that their physical similarity was due to Earth being a [[TransplantedHumans long-forgotten Centauri colony]]. Human scientists, no doubt keeping the fossil record in mind, got hold of some Centauri DNA and disproved this claim. The Centauri saved face by claiming "clerical error" had mislabelled Earth as a lost colony.
* The aliens on ''Series/ThirdRockFromTheSun'' mention a few times that they've taken on human form and describe their natural form as being "purple tubes". They seem to have picked their human bodies from a catalogue. [[spoiler: Vicki's son Eric]], fathered by the Big Giant Head in his human guise, looks like a perfectly ordinary human baby and is rejected by the tabloids because [[spoiler: Vicki]] didn't even try to make him look more "alien".
* ''Series/OdysseyFive'' had Synthetics, which were human bodies created by artificial intelligences. At one stage the team consult a sci-fi writer, pretending they're looking for help with a sci-fi novel. The writer complains how cliched the idea of Synthetics is: [[ConversationalTroping "It's just a cheap tool TV shows use to save on special effects!"]]
* A nice HandWave comes from the TV show ''SomethingIsOutThere''. "God created human beings in his image, right? How many images do you think he has?"
* Pax and Crona from ''[[{{Vintergatan}} At The End Of The Milky Way]]'' both look human, but with three differences -- they constantly crave sugar, their hair changes color depending on their emotions, and they make quick, pig-like noises when they're upset. Strangely enough, only Pax shows the two last signs, leading one to believe that it's either an InformedAbility for Crona, or he's just so slick he never changes emotion from 'groovy'.
* The aliens in ''TheEvent'' are distinguished from humans only by their longer lifespans and certain undescribed "skeletal and serological abnormalities". The latter are pronounced enough that a blood test will reveal them, and one plants himself with a tube of human blood to avoid arousing suspicions during a blood test. A DNA test will also reveal them, and [[EvilDetectingDog dogs sometimes bark at them]].
** They are able to interbreed with humans, though.
* So you're watching ''[[Series/BlakesSeven Blake's 7]]'' and you find yourself wondering whether the very-human looking primitive tribe on this episode's guest planet are alien humanoids or descendants of a lost human colony? Don't bother thinking about it that hard. The series itself even lampshaded this in the 4th season:
-->'''Vila''': Everyone came from Earth originally. That's a well-known fact.
-->'''Soolin''': It's a well-known opinion, actually.
-->'''Tarrant''': Most well known facts are.
* ''Series/{{Animorphs}}'' did this most of the time with Ax and Visser Three, keeping them in human morph for budget reasons (their natural forms being blue centaurs with scorpion tails and antennae topped by extra eyes). It was a *lot* more common than in the books.
* Cole and possibly (but not for certain) Zin in ''{{Tracker}}''. The rest were alien life forces inhabiting human bodies.
** Even Cole took human from from an underwear ad. They later encounter the male model who posed for the picture.
* In the 2007 SciFiChannel version of ''Series/FlashGordon'', Flash calls the inhabitants of Mongo "aliens" even though they look entirely human and [[AliensSpeakingEnglish speak English]] (which is lampshaded, but not explained).
** Most physiological differences between the "races" of Mongo are explained by corrupted water sources.
* ''TheMiddleman'' gives us the Manicoids, who are just human-looking enough to pass for plastic surgery victims; and the Clotharians, who look like human teenagers or young adults (the odd man out being High/Maximum Aldwin, who appears as a humanoid adult).
* ''Series/TheAdventuresOfPeteAndPete'' usually stuck to MagicalRealism or surrealism rather than out-and-out science fiction, but the special "Space, Geeks, and Johnny Unitas" revealed that [[spoiler: Joe Jones]] was in fact an alien, presumably from Alpha Centauri
* ''Series/WizardsOfWaverlyPlace'' played this with the aliens who land at Waverly Place in the episode "Wizard For A Day" to steal Jerry's milkshake machine who wear silver suits and have dealy-bobs coming out of their heads, but otherwise look just like us. You'd probably see weirder things on an average day in New York.
* ''Series/TheTwilightZone'' episode "Third from the Sun" appeared to show two families preparing to escape to a planet of Human Aliens. [[spoiler: At the end it is revealed that ''they'' are the Human Aliens and the planet they are traveling to is Earth.]]
[[/folder]]

[[folder:Radio]]
* ''Radio/TheHitchhikersGuideToTheGalaxy'' has several examples, most notably Ford and Zaphod's unnamed species from the Betelgeuse system (the latter's extra head and arm are due to surgery). The only known differences are biological incompatibility with humans and multi-centennial lifespans.
** The Asgoths of Kria (writers of the second worst poetry in the universe) are also likely to be this way on account of how precise Douglas Adams tends to be with his language - after all, their poet's small intestine throttled his brain in 'a desperate attempt to save ''humanity'''. In the very next episode, Arthur compliments the 'humanity' of a Vogon poem, which Ford hastily corrects into 'Vogonity', decreasing the likelihood that this was a mistake.
** Possibly {{Justified}} by the reveal that Earthmen are a designed species created by aliens... and by the still later reveal that they are in fact descendants of AncientAstronauts from Golgafrincham.
[[/folder]]

[[folder:TabletopGames]]
* ''TabletopGame/CallOfCthulhu''. The secretive inhabitants of the subterranean city of K'n-Yan are almost completely indistinguishable from humans.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/SuperRobotWarsOriginalGeneration'' reveals that all the Human Aliens are actually humans, who left Earth long ago voluntarily. The Mysterious Lovecraftian Aliens refer to Earth as the "Land of Beginning", where sentient life first evolved.
* ''GalacticCivilizations II'' has a race called the Altarians, who are essentially Humans With PsychicPowers. The Altarians even call the [[HumansByAnyOtherName Terrans]] their "lesser cousins." It's implied in the backstory, however, that the two races might have a common origin.
** That being said, the game makes it clear they are two separate species, and unlikely to be compatible for reproduction (no one has really tried). Furthermore, everyone in the game notes that the physical similarities between the two species are very strange and seemingly fly in the face of science.
*** Specifically, certain Altarian research options with ''Dark Avatar'' notes that a) Altarians and Terrans are two separate species, b) Altarians are more genetically similar to Terrans than they are to any species on their home planet.
** The evil {{Precursor}} Dread Lords are also noted to look similar (though at the same time they are clearly a separate species) to humans, which disturbs everyone. [[spoiler:It turns out that this is because the Dread Lords' creator, the Mithralar Draginol, is himself an ascended time-travelling human. The heavy Dread Lord presence on early Altaria (as demonstrated in the backstory of the ''Elemental'' fantasy spinoff series) is probably significant to that planet's natives' resemblance to humans as well.]]
* ''VideoGame/StarControlII'' is mostly pretty good about making its aliens different from humans, though there are still a suspiciously large number of bipeds with heads on the top. However, one species, the Syreen, are your typical [[GreenSkinnedSpaceBabe blue-skinned space babes]] - and they comment on the perplexing similarity between their species (the big difference being matriarchal rather than patriarchal). They're so close, in fact, that they're apparently sexually compatible, capable of producing fertile offspring. It is implied in the game's rich backstory, however, that it's because a [[LittleGreenMen certain other alien species]] transplanted some ancient Syreen to Earth as part of an extremely long-term experiment.
* The Lunarians in VideoGame/{{Touhou}} are basically this. But then again, they might be [[EpilepticTrees merely ascended humans]] after all, and the ending of ''Imperishable Night'' describes them as having aspects of [[HalfHumanHybrid both humans and youkai]].
** To be fair, Gensokyo is pretty much a FantasyKitchenSink inhabited by a variety of mythological creatures that all look quite human and rather attractive, [[CuteMonsterGirl even at their most bizarre]]. A lot of the youkai themselves could qualify for this trope.
* Similarly, the Lunarians in ''VideoGame/FinalFantasyIV'' don't look too different from humans other than slightly different skin tones and hair colors. They can even interbreed with humans and the two major characters are [[HalfHumanHybrid Half-Lunarian]].
* ''VideoGame/FinalFantasyX''[=/=]''[[VideoGame/FinalFantasyX2 Final Fantasy X-2]]'': By all outter appearances, [[GeniusDitz Rikku]] is virtually indistinguishable from humans, despite being an Al Bhed. Which becomes a minor plot point in ''FF X'', when Tidus lampshades the fact that Wakka [[FantasticRacism hated the Al Bhed]], yet failed to realize [[http://www.youtube.com/watch?v=3FPKmKYyBA4 Rikku was one of them.]]
* The vast majority of the alien races in ''StarOcean'' are human or PettingZooPeople. This may be [[JustifiedTrope justified]] by the third game's ShockingSwerve if [[FridgeBrilliance the player thinks about it]].
* The D'ni in {{Myst}} count, as they evolved on a different planet. Up until URU introduced the Bahro, all sentient inhabitants of D'ni-linked worlds were humanoid, suggesting that some part of their linking technology automatically avoids creating links to worlds with non-humanoid inhabitants for some reason.
** There is some precedent for such an interpretation, even given the Bahro. D'ni law (although not any actual aspect of The Art) required all ages to conform to certain environmental conditions, for safety reasons. Since these conditions fostered the evolution of the D'ni, it stands to reason that they would foster the evolution of biologically similar races, especially if they were sufficiently constrained.
** This also explains why they look human; D'ni itself is underground on Earth, but is itself a colony from a forgotten homeworld.
* The Theians of ''IronGrip''.
* Niles Van Roekel in ''VideoGame/MarvelNemesisRiseOfTheImperfects''.
* Going along with ''Franchise/StarWars'' above, ''VideoGame/KnightsOfTheOldRepublic'' has several. Juhani looks like a human with tattoos and an odd accent, the Handmaiden (and by extension the entire Echani species) look like humans with [[MysticalWhiteHair white hair]] and silver eyes (and can interbreed with humans), Visas and Miraluka in general look exactly like humans until you remove their hoods (they don't have eyes), and there is a Zeltron minor character on Telos near the beginning.
** Note that many ''Franchise/{{Star Wars|ExpandedUniverse}}'' species are actually 'near-Humans', meaning that they are descended from Humans but evolved into something else because of long-term genetic isolation. This is because before the Hyperdrive was invented, people traveled around in generation ships or sleeper vessels; some limited interspecies contact occurred, but no organization on the scale of the Republic or Empire was possible. Also, not all isolated Human populations diverged genetically if their new environment was benign enough; for example, the inhabitants of Naboo stayed well within the Human genetic range, but diverged from mainstream humanity culturally. Apparently, [[UnfortunateImplications Indians are an aberration]].
** Juhani's appearance is due to technical limitations, in [[http://starwars.wikia.com/wiki/Cathar other media]] and [[VideoGame/StarWarsTheOldRepublic the MMO]] the race is fur-covered and much more feline.
* While not referred to as aliens, many of the demons from ''Franchise/{{Disgaea}}'' fall under this, since we see that they do inhabitant different planets throughout space. In the second one, it's an even a major plot point that [[spoiler:Axel]] is a demon indistinguishable from humans.
* ''VideoGame/EscapeFromStMarys'': You first think you're looking for a shriveled green man, for your search's actual result turns out more like this.
* [[spoiler: Waka]] from {{Okami}} is actually [[spoiler: a survivor from the Moon Tribe]]
* The Masari from ''UniverseAtWar'' are most certainly this, as is the species that created Novus.
* If you put it this way, the ''KingdomHearts'' series resolves around space travel, though all the worlds were originally one. Many of them contain humans ([[WesternAnimation/{{TheNightmareBeforeChristmas}} though there]] [[Disney/{{TheLionKing}} are some]] [[Disney/{{LiloAndStitch}} exeptions]]), and the human characters you control can be considered aliens. Though the only one ever called that, indirectly, was Terra, [[spoiler: when he was "saved" by Gantu and shown, unconscious, to the Grand Counselwoman]].
* ''VideoGame/{{Homeworld}}'' has the Hiigarans (consequently their descendants, the Kushan [[spoiler:and [[LongLostRelative Kadeshi]]]]), [[TheEmpire Taiidani]], [[HordeOfAlienLocusts Vaygr]], [[TheFaceless apparently]] the [[ProudMerchantRace Bentusi]] and possibly everyone else (given that their ships, once captured, [[PossessionImpliesMastery instantly can be fielded against them]]).
* Olimar and others from Hocotate in ''{{Pikmin}}''. It's implied that he lands on Earth AfterTheEnd. The most obvious difference between Olimar's people and humans are their height: They're extremely small, with Olimar not even being 2 centimeters in height.
[[/folder]]

[[folder:Web Comics]]
* ''WebComic/EerieCuties'': Jeffery, the groundskeeper at [[AllGhoulsSchool Charybdis Heights]] purposely [[http://www.eeriecuties.com/strips-ec/a_little_wuv tries to scare humans away]] and Layla does what she can to [[http://www.eeriecuties.com/strips-ec/sneezeweed scare them off as well.]] Yet, no one finds it strange that there's [[http://www.eeriecuties.com/strips-ec/carefully_hidden a human science teacher]] working at their school... or is she? The cast page even list Proff. Twiggit's species as [[http://www.eeriecuties.com/cast/ "(human?)"]], suggesting she may not be what she appears.
* In ''Webcomic/TheEnd'', most aliens are portrayed as being well and truly alien (huge six-eyed birdlike humanoids, UglyCute slug-people, etc.) The Ith, however, stand out.
-> '''Henri''': '''Those''' are Ith? You said they were '''similar''' to us.
-> '''Ethma''': Are they not?
-> '''Henri''': No! They're '''exactly''' the same!"
* The Narvans, and the Amazons ''Webcomic/{{Tripp}}'' & co. encounter in their first attempt to vortex-jump.
* In ''Sev Trek'', the Enterprise is making FirstContact with the Obscuricons. Kirk asks Spock what type of beings they might be. After long speculation on StarfishAliens types, a human looking alien beams up instead.
-->'''Kirk:''' What were you saying, Spock?
-->'''Spock:''' I see; [[BoldlyComing you visited this planet too]].
[[/folder]]

[[folder:Web Original]]
* The Tautiq, a race of alien refugees who now live on earth in the ''GlobalGuardiansPBEMUniverse'', basically look like taller, thinner humans with odd hair-and-skin color combinations. They aren't "sexually compatible" with humans, either, but you can't tell that without seeing them naked.
** The Pelkons, another group of alien refugees who now live on earth are even more human-like than the Tautiq, (the primary difference are leopard-like spots on their chests and backs and milk-white, pupilless eyes), as they ''are'' "sexually compatible" (but are not cross-fertile) with humans.
* Almost all characters in ''ChaosFighters'' are this. The exceptions are [[spoiler:Irtial and Muranyl, who are from Earth.]]
[[/folder]]

[[folder:Western Animation]]
* In ''WesternAnimation/Ben10AlienForce'', Alan is a [[HalfHumanHybrid Pyronite crossbreed]] who looks human except for when he's using his powers, and it's revealed that [[spoiler: Gwen (and of course Ben by extension) is a HalfHumanHybrid]] and gets her powers from her alien grandmother (the logical extension is, of course, that anyone without an Omnitrix strapped to their wrist who has powers is an alien or part-alien. The fans have had fun with this).
** Hex and Charmcaster are humans from an alternate dimension, making them literal Human Aliens.
* [[WordGirl [=WordGirl=]]] is an alien from the planet Lexicon, but looks nothing remotely exotic.
* Just about everyone in ''WesternAnimation/WinxClub'' are from different worlds, but they all seem to be just as human as people from Earth are.
* ''SymBionicTitan'' has the Gallalunans, who seem to blend in with the Earthlings very well.
* The GoBots looked completely human before becoming a race of cyborgs. The only two remaining Gobotic humanoids are the Last Engineer and the Master Renegade, who were discovered in [[HumanPopsicle suspended animation.]]
* Humorously inverted in the very first "Treehouse of Horror" episode of ''TheSimpsons'': Kang and Kodos look nothing like human beings, but, [[HandWave "by an astonishing coincidence"]], their language, Rigelian, is exactly the same as English!

!!Aversions and subversions

[[folder:Anime]]
* ''Anime/NeonGenesisEvangelion'', oddly enough several of the Angels are roughly humanoid, others are more... [[EldritchAbomination interesting.]] Notably, the two most powerful ones are basically cloned {{Half Human Hybrid}}s.
** But it's not surprising considering that in the Eva universe, [[spoiler:humans were descended from the 2nd Angel, Lilith. As such, one of the aforementioned {{Half Human Hybrid}}s (Kaworu) refers to humanity as "Lilim". Then in ''End of Evangelion'' Misato puts forth the theory that humanity, collectively, is the 18th Angel.]]
[[/folder]]

[[folder:Film]]
* The First Breed from ''His Majesty's Starship'' look nothing like humans. Although books are naturally far less vulnerable to this trope than LiveActionTV, given that it takes significantly less effort to write a character as a "20-foot arachnid" than it does to act said spider.
* Prot in ''Film/KPax'' explains this by saying that it is the most energy-efficient form to take on Earth. Of course, he [[spoiler:may or may not be an alien]].
* In the earlier film which might have inspired the novel, an Argentinian production called ''Hombre Mirando al Sudeste'' (''Man Looking Southeast''), Rantes explains to the doctor that though they came in a ship, he and the others are actually physical [[ProjectedMan projections]] from a distant, doomed future on another planet, and that they naturally adapt to whatever the observer [[WeirdnessCensor expects to see]]. Of course, he [[spoiler:may not be an alien, either -- though he does have PsychicPowers, and his equally-alien (?) female friend does leak blue liquid from her mouth when excited]], and then again, he also claims to be a MessianicArchetype... yeah, it's one ''hell'' of a MindScrew.
* Both the {{Transformers}} & the Brave Series have a weird variation on this, wherein there are several planets besides Cybertron/whatever planet the heroes come from that are inhabited by intelligent TransformingMecha. Sometimes explained as being colonies of the main characters' race, sometimes not. While it may be reasonable to assume that a sufficiently advanced civilization would discard their weak organic bodies for more durable mechanical ones, the whole transforming thing is pushing it. The weirdest example being the Japanese Anime/BeastWarsII series, where there is a planet of highly evolved FunnyAnimal-like aliens who have developed to the point of Trans-funnyanimalism, where they have upgraded themselves with cybernetics. This allows them to turn into humanoid robot forms that look uncannily like the Maximals & Predacons, despite having no prior contact with them, for no apparent reason other than RuleOfCool.
* Mostly averted in the ''Franchise/StarWars'' series. It does feature a few human-looking (possibly) aliens. In some cases those may just be human colonies. It also features plenty of RubberForeheadAliens. The long history of humanity in the Star Wars galaxy allows for the possibility of so-called "near-human" races that are evolutionary descendants of mainstream humanity, but which have evolved to adapt to different planetary environments. Then there are also many species that are very non-human-looking. It's a richly diverse galaxy.
* Subverted in ''Film/GalaxyQuest,'' as the aliens initially appear human, but are using technology to change their appearance because their true form is . . . unsettling.
* Subverted in the remake of ''Film/TheDayTheEarthStoodStill2008''; Klaatu's human form is implied to have been grown inside his initial containment suit to allow him to be compatible with the Earth's environment.
* In ''Film/{{Lifeforce}}'', when the astronauts explore the vampire spaceship they are astonished to discover a humanoid crew in stasis pods. Subverted when it's discovered that they're actually shapeshifting monsters who assumed human form to more easily find and seduce human victims to snack on their souls. Their real form is some sort of extraterrestrial, winged bat creature.
[[/folder]]

[[folder:Literature]]
* Averted in the novel ''Quest'' by Andreas Eschbach, when it is explained that: 1.All human races originated on earth and just evolved differently due to different environments. 2.All of the galaxy's life originated on one planet and cells of it have been spread by comets.
* Averted in the novel ''Transformers: Ghosts of Yesterday'' (a prequel to the film), where Starscream claims that any sufficiently advanced race would naturally build machines that were similar to Cybertronians, as the Decepticons believe that they are the most perfect lifeforms in the galaxy. However, he also may have been simply trying to explain away the fact that the human spaceship ''Ghost 1'' seemed to be built using Cybertronian technology (i.e. that Megatron, the Decepticons' true leader, has been found).
* Conspicuously and consciously avoided in Wayne D. Barlowe's illustrated sci-fi novel ''Expedition''. Barlowe, a noted fantastic fiction illustrator who darn well knows his biology, openly despises this trope and so he invented an alien race who is very like humankind in their attitude and culture - [[spoiler: but they look a bit like a cross between a hot air balloon and an [[SpaceWhale airborne octopus]].]]
* In Creator/LarryNiven's ''Literature/{{Ringworld}}'' series, there are various humanoid races who all turn out to be [[spoiler: descended from the same race of {{Precursors}} who are the ancestors of Earth humans]].
* The Martians and Venusians of SMStirling's ''TheLordsOfCreation'' novels look human because they are (more or less); the eponymous beings, in prehistoric times, Terraformed Mars and Venus and seeded them with Earth life (repeating the process several times, so that on Venus you have humans sharing the planet with dinosaurs and mammalian megafauna).
* The aliens in Robert Zubrin's TheHolyLand consider themselves the humans, and the Earthlings merely 'proto-humans'. Given their superior senses, telepathic ability, superior physiques, and [[ArsonMurderAndJaywalking superlative hygiene]], they're probably right. However, they themselves originated on Earth, about twenty thousand years ago.
* ''Literature/TheHitchhikersGuideToTheGalaxy1'' has a subversion in the book version with Trillian. When she's introduced, she's built up to be one of these. [[spoiler:She's from Earth.]]
* In the ''YoungWizards'' series, two of the four alien species involved in the wizardly cultural exchange program look human. And there's a guest appearance by a [[Series/DoctorWho Time Lord]]. A few of the {{Mooks}} are RubberForeheadAliens. All the rest of the aliens are definetly not human, with a few of them being StarfishAliens.
* Some of the ''Franchise/DoctorWhoExpandedUniverse'' novels have the Doctor come across as mildly not-so-human, to generally [[UncannyValley creepy]] effect. Anji seems to be particularly prone to noticing this. In one scene, when he does strike her as a convincing human, she considers him "a fake" and refers to him as "the alien" and "it" before she remembers he is, after all, [[PlatonicLifePartners her friend]] and a nice guy. In another scene, they'd have ''really'' run up the special effects budget if it were TV, just to make people go "[[{{Squick}} Ewwww]]" at the protagonist:
-->In [[GentleGiant Hugo]]ís arms, the Doctor hung bonelessly limp, as if he might suddenly flow to the floor in a puddle. Anji had never seen a human body sag like that; no human being had that sort of muscular-skeletal frame. For a frightened instant, she felt more kinship with the man with no limbs[[note]]they're at a sideshow[[/note]] than she did with the Doctor.
* Averted in the ''SectorGeneral'' series. Sure, they have one species of Human Alien, but they have seventy species total, so that is to be expected eventually. There are also species which look nothing like humans but look a lot like each other, inverting the trope.
* ''Literature/{{Animorphs}}'' pointedly averts this trope. The most humanoid alien ever mentioned in the series is a species of amphibious monkey. Also, the Hork-Bajir feature basically the same head/two arms/two legs body shape, but otherwise go even beyond RubberForeheadAliens (in fact, they more closely resemble dinosaurs). The torsos of Andalites look fairly humanoid, and the head has a RubberForeheadAlien quality to it, but otherwise they are very different (having a basic body structure like a Centaur). Aside from those three, none of the alien races/species portrayed or mentioned in the books look anything even remotely human. Some of them even stray into StarfishAlien territory. Elfangor reflects that humans are the only bipedal species he's ever seen or heard of that can balance without a tail.
** Played straight with the Inspector. He is a Yeerk Controller whose host body looks exactly like an Andalite, except it has no tail blade, and moves extremely quickly.
** In one book, Aximili lampshades the trope, complaining that Star Trek aliens are completely unrealistic and make no sense.
[[/folder]]

[[folder:Live Action TV]]
* ''Series/BabylonFive'':
** The Vorlons are so alien looking that for the first two seasons we don't know how much of them is clothing and how much is their real body. Their true form appears to some kind of energy being, but every species perceives a Vorlon to look like their species version of an angel -- it is suggested that this is the result of the ancient Vorlons having not only genetically tweaked the other species, but also appeared to them ''as'' angels at appropriate times in their respective development, creating a basis for the legends, taking advantage of them, or both.
** After FirstContact the Centauri initially claimed that humanity was an offshoot species derived from an ancient colony of theirs. This was proven false when the Earth Alliance managed to get hold of a sample of Centauri DNA; the Centauri called it a mistake due to a clerical error. (The human reaction amounted to, "Ha ha, very funny.")
* ''Series/{{Firefly}}'', a verse with AbsentAliens, pointedly avoids this trope. If the people on the next planet over look human, that's because they are. The movie revealed that this is because it's all one solar system terraformed by Earth colonists.
* ''Series/StarTrekTheNextGeneration'' had a weird variation once: apparently, it's not just humans that have doubles. "Who Watches the Watchers?" features a alien species that are physically identical to ''Vulcans'' (or at least Romulans, who are basically Vulcans with a ridge to make them distinct from their Federation cousins) without being a descendant. Strangely enough, they were apparently also ''mentally'' similar to Vulcans (the whole logic thing).
** Between them Series/StarTrekTheOriginalSeries and Series/StarTrekEnterprise played with it for the Klingons. In TOS, the Klingons look human enough, in everything else they are ''the'' RubberForeheadAliens. Turns out they tried to create super-Klingons based on ''human'' Augments. The attempts to salvage the situation when things inevitably go wrong led to a significant portion of the Empire effectively becoming Klingon-Human hybrids visually indistinct from humans (the alternative was to have a significant portion of the Empire become ''dead'' Klingon-Human hybrid Augments).
*** Before this, the LiteraryAgentHypothesis was GeneRoddenberry's official explanation: All the aliens don't look human, there just wasn't the budget to make everyone look the way they do in his head. (You'll notice for a Klingon to pose as a human it took ''surgical alteration'' and not just a haircut. This is apparently why.)
* Subverted in an episode of ''Series/TheTwilightZone'' in which astronauts are surprised to find Mars inhabited by human beings.
* Famously subverted in ''Series/{{V}}'' - the Visitors ''present'' themselves as Human Aliens, but are really [[TheReptilians Reptilian Aliens]] using LatexPerfection to disguise themselves.
** The remake lampshades this in the pilot, when a reporter asks Anna how it's possible for them to look like humans despite scientists claiming that aliens wouldn't look like that. Anna retorts that ''their'' scientists have determined otherwise.
[[/folder]]

[[folder:Radio]]
* Parodied in the ''Captain Kremmen'' radio spoof, when Kremmen first encounters the Thargoids.
-->"Except for their large transparent heads, three lips and sixteen nostrils, they looked just like you or I!"
[[/folder]]

[[folder:Tabletop Games]]
* Subverted in ''Cthulhu Tech''. The Nazzadi look like RubberForeheadAliens, but that is because they are actually genetically engineered from humans by the very alien [[StarfishAliens Migou]].
* ''{{Traveller}}'' RolePlayingGame both uses ''and'' subverts this; there are humans and humanoids [[TransplantedHumans spread]] by mysterious {{Precursors}}, and there are StarfishAliens, some of them ''very'' alien.
* Eldar from WarHammer40000 look like humans with pointed ears and angular features in art. However, it's made clear in descriptions that no-one would ever make that mistake in-universe due to the weird boneless way they move, their fingers being compared to writhing worms.
[[/folder]]

[[folder:Video Games]]
* ''Franchise/DeadSpace'' has an ironic subversion, since all the Necromorphs are made from human corpses and several of them look pretty damn close to a plain old human.
* ''{{VideoGame/Ascendancy}}'' not only does ''not'' have HumanAliens, it doesn't even have humans. ''All'' aliens in the game are StarfishAliens. The most recognizable are the Chamachies, being a race of LizardFolk with chameleon (i.e. turreted) eyes. Then there's a race whose people are made up mostly of a giant eyeball (unsurprisingly, they're called Oculons).
* ''VideoGame/TheLastFederation'', like ''{{VideoGame/Ascendancy}}'' above, does not have humans in it. Player character is a hydra looking alien, one alien race is a bug species, one looks like TheGreys, two are robots, one we do not get a good look at all and one looks like an barn own. The last one looks humanoid, but is red, seems to have a carapace and lacks visible mouth.
[[/folder]]

[[folder:Webcomics]]
* AlienDice has numerous examples of aliens who look similar to humans but with subtle differences, such as exotic HairColors or CuteLittleFangs. It also has a rather interesting subversion when it is [[TheReveal revealed]] that [[spoiler:the reason that the blueskinned Rishan look human is because they '''are''' human, having been created using genetic material taken from Earth humans generations ago]].
* ''Webcomic/ElGoonishShive.'' Aliens and magical beings get around by wearing T-shirts that say "Human" or some such. (''One'' person notices that his coworker is an alien. Her denying it is enough to convince the others, and she and this coworker wind up sending silly notes back and forth to each other about it.) Of course, Uryuoms being natural shapeshifters ''and'' the creators of TransformationRay technology, they could hide by simply becoming human. Of course, [[RuleOfFunny that wouldn't be funny.]]
** Two of them hire Ted (seen in a flashback) to design human forms for them, and provide the technology for it - apparently there are legal/political/religious reasons why they can't do it themselves (because it requires the use of object-oriented programming), rather than an inability to do it themselves. Also, once they've been raygunned into humans, they can (implied) shift back and forth freely.
** It gets better. Uryuoms don't consider themselves actual aliens--as one of the pair who hired Tedd said, he's a natural-born American! Hence the above argument--the other characters knew she wasn't ''human'', but she's not ''alien''. Wonderful thing, jus soli, eh?
* ''TheInexplicableAdventuresOfBob.'' Except for the cameo crossovers with ''{{Melonpool}}, {{Zortic}},'' and ''Zeera the Space Pirate,'' all aliens depicted have been [[StarfishAliens nonhumanoid]] in their true forms--although the Nemesites will typically [[VoluntaryShapeshifting disguise]] themselves as humans when dealing with Earthlings.

[[/folder]]

[[folder:Western Animation]]
* {{Inverted}} [[PlayedForLaughs For Laughs]] in ''WesternAnimation/InvaderZim''. [[VillainProtagonist Zim]] looks nothing like a human (having green skin, antennae and no nose or ears), but with a minimum of effort absolutely nobody on Earth notices except for [[HeroAntagonist Dib]].
** But he has [[PaperThinDisguise his human disguise]]! He puts in his contacts and wears a wig - INGENIOUS!!! [[http://www.quizilla.com/user_images/P/PorkCow/1042793471_InvaderZim.jpg evidence]]
* Captain Crandall of ''WesternAnimation/TeamoSupremo'' claims to be from another planet, despite the fact that he looks too much like his "Earth-mom" to possibly not be her child.
* Subverted in ''WesternAnimation/MonsterBusterClub''; Cathy seems like a Human Alien at first glance... but various lines indicate that this is just a human disguise like we see on other aliens in the series, and her true form hews closer to the StarfishAliens trope.
