History Main / TheReptilians

* Meme went around claiming that Music/JustinBieber was one. It started with a video of Bieber's eyes becoming reptile like during a supposed glamour failure. This was actually a common video compression glitch that caused the pupils to appear vertically elongated. Bieber wasn't the first celebrity where conspiracy theorists noticed the glitch, but he was the one who people thought was the funniest.

* InfiniteWorlds for the ''TabletopGame/{{GURPS}}'' has an Earth that feature lizards. It is called "The United States of Lizarda". GURPS had created a stat for these lizards by loosely based on Dale Russell's opinion. (See Dale Russell's opinion below in the Real Life section.)

** The Race is a species of chameleon-like reptilians whose strong sense of cultural pride drives them to try and conquer Earth. The two species (Rabotevs and Halessi, though those are probably the Race's names for them) they subjugated before invading Earth are also reptilian in nature, as they are mentioned as being fairly similar to the Race.

* Creator/HPLovecraft's denizens of the Nameless City are describe as "an unnamed race of reptiles with a body shaped like a cross between a crocodile and a seal with a strange head common to neither, involving a protruding forehead, horns, lack of a nose and an alligator-like jaw".

* The very bestial-looking Hork-Bajir from the ''Literature/{{Animorphs}}'' series are a highly atypical example. They make up a large portion of the evil [[PuppeteerParasite Yeerk]] army due to their large size and numerous blades all over their bodies, but when free from Yeerk control they're naturally docile creatures who use their blades to [[HerbivoresAreFriendly slice bark from trees for food]]. They are among the less sharpminded sapient aliens portrayed, but every few generations a "Seer" is born with very acute mental faculties.

* ''Series/LandOfTheLost'': The Sleestak, who serve as the main villains of the show, and the Altrusians, who even though they are the ancestors of Sleestak are different enough both physically (they're shorter, stockier and with an extra finger) and mentally (they're far more intelligent) to qualify as a separate race.

* ''Series/StargateSG1'' has the Unas. They are a species that lives primitively and is a race of hunters. On some planets, they are also the slaves of humans. They were the first hosts for the Goa'uld before they preferred to take humans as hosts.

** The Gorn. Most famously one had a duel with Kirk in the original series. In other media they've been more neutral, or in Videogame/StarTrekStarfleetCommand they're actually allies of The Federation

* The ''Series/{{V 2009}}'' reboot series took no motion to change any of this. Except the Visitors were more of a combination of [[WhatMeasureIsANonCute yucky reptile-people and icky bug-people]]. The reboot also has them literally grafting human skin onto their scales. One of the ways of punishment for the [=Vs=] is to be skinned alive, which causes just as much pain as it would a human, since the grafted skin has perfectly working nerves. There's also the possibility of [[HalfHumanHybrid interbreeding]] between humans and [=Vs=].

This was actually a common video compression glitch that caused the pupils to appear vertically elongated. Bieber wasn't the first celebrity conspiracy theorists noticed the glitch on but he was the one people thought was the funniest.

* The Visitors from ''Series/V1983'' are the {{Trope Codifier}}s. They infiltrate many parts of human society, and they want to ''[[ToServeMan eat us]]'' (along with other tasty mammals). Rather than shapeshifting, however, they use fake human-like skin to mask their true appearance, a method best exemplified by the iconic shot of Diana peeling back the skin on one side of her face to reveal green scaly skin and a catlike eye. It should be noted that, aside from [[FollowTheLeader inspiring the creation of other fictional Reptilians]], ''V'' led to the plethora of conspiracy theories about Reptilians, which were pretty much nonexistent before the show aired.

* In ''Series/WarOfTheWorlds'', the Martians are essentially turned into the aforementioned Visitors. Except that they're body snatchers.

** The Silurians and their aquatic cousins the Sea Devils[[note]]both of these are technically FantasticSlurs: the ''Franchise/DoctorWhoExpandedUniverse'' has "Earth Reptiles" as a more respectful term, and the Eleventh Doctor uses the taxonomically inaccurate "''Homo reptilia''"[[/note]]. They are not extraterrestrials, but the previous inhabitants of Earth before humans came around. They do live underground and abduct people, though, which still fits in with Reptilian lore. There are also the Ice Warriors, the inhabitants of Mars, though their reptilian features aren't emphasized as much.

* ''Series/LandOfTheLost'': The Sleestak, who serve as the main villains of the show, and the Altrusians, who even though they are the ancestors of Sleestak are different enough both physically (they're shorter, stockier and with an extra finger) and mentally (they're far more intelligent) to qualify as a separate race.
* ''Series/{{Farscape}}'': The extremely brutal Scarrans, who create one of the two [[TheEmpire evil empires]] of the show. The one HalfHumanHybrid we see of them is also a vicious ManipulativeBastard. He also requires technology to survive (cooling rods in the brain that have to be replaced regularly), as his reptilian half craves heat, while his HumanAlien half can't stand it.
* The Drazi, along with other less significant species, in ''Series/BabylonFive'', although their ProudWarriorRace personalities are a bit different from the metaphorically cold-blooded norm, and were not hostile to Humans (during the [[HopelessWar Earth-Minbari War]] they were the one member of the League of Non-Aligned Worlds to send warships to help Earth. Even after their fleet 'disappeared' in hyperspace and they were forced to neutrality, they still gave Earth the plans for a WaveMotionGun to mount on defensive satellites). The Drazi do engage in random ceremonial war with one another in one episode, which proves to be a hazard [[spoiler: until Ivanova inadvertently forces them to stop]].
* One episode of ''Series/BuckRogersInTheTwentyFifthCentury'' involved Reptilian aliens disguised as humans. Buck exposed them by lowering the temperature. Being cold-blooded, they collapsed.
* ''Series/{{CSI}}'' had an episode dealing with this trope, "Leapin' Lizards", where the dead guy of the week was a believer in a reptilian conspiracy. Their website is shown, with several world leaders morphing into reptilians, and one of the guys hallucinates Brass with a reptilian tongue and Greg with reptilian characteristics-which leads to Greg being bitten.
* ''Series/StargateSG1'' has the Unas. They are a species that lives primitively and is a race of hunters. On some planets, they are also the slaves of humans. They were the first hosts for the Goa'uld before they preferred to take humans as hosts.

Since they are reptiles they, of course, [[ReptilesAreAbhorrent are almost always evil]]. Unlike their Grey and Green cousins, though, the Reptilians tend to be portrayed as [[AlwaysChaoticEvil even more vicious and sadistic]], often abducting humans as a SlaveRace or as a [[ToServeMan food source]]. They are frequently [[VoluntaryShapeshifting shape-shifters]], changing into human form in order to infiltrate our ranks and take over the world before we even realize it. Sometimes, like LittleGreenMen and TheGreys, they can be more enigmatic invaders whose only direct contact with humans is through abductions. The trend nowadays, though, has been to give The Reptilians a more detailed culture than those two, typically as either ScaryDogmaticAliens or as the vanguard of a vast but decadent empire. They commonly have hidden bases BeneathTheEarth, which probably stems from a fusion of the {{Primal Fear}}s of both reptiles and the underground. Oftentimes, they are mentioned as having created TheGreys (by [[CloningBlues cloning]]) as a SlaveRace, until some decided to rebel, thus necessitating the Greys to [[LEGOGenetics steal human DNA to survive.]]

If the biological history of the Reptilians gets mentioned, they are frequently revealed to be dinosaurs who attained sapience, somehow survived the K/T Extinction event, and [[{{Ultraterrestrials}} moved elsewhere among the stars]], not necessarily in that order.[[note]]To be technical, many believe humans and other mammals themselves evolved from reptilelike synapsids, so having the Reptilians actually remain what humans would recognize as reptilian would be quite a stretch, especially if they moved to a planet with a very different environment from Earth's to evolve in. Doesn't help that most dinosaurs weren't very "reptilian" in appearance, with feathers and the like -- sapient dinosaurs would look more like birds than anything else.[[/note]] Such dinosaur-derived creatures are sometimes called "Dinosauroids", a term first popularized by paleontologist Dale Russell's hypothetical ''Troodon''-descended humanoid. Naturally, those dinosaurs often turn out to have been descendants of the carnivorous theropods such as ''[[RaptorAttack Velociraptor]]'' or ''TyrannosaurusRex'' (it helps that many theropods are considered to have been the most intelligent dinosaurs there were). Alternatively, they evolved on a planet whose evolutionary history is just like that of Earth, but [[EvolutionaryLevels stalled out]] before mammals could take their [[HumansAreSpecial rightful place at the top]].

** The vesk are a ProudWarriorRace of ScaryDogmaticAliens who control a powerful militarized and have formed an uneasy alliance with the Pact Worlds, after being forced to put their original plans for first contact -- armed invasion and subjugation -- on indefinite hold by the arrival of [[SwarmOfAlienLocusts something even worse]].

-->"On Nal Hutta, the [[ScaryDogmaticAliens Vong]] are invaderz. What doez one call them on Barab?"\\

* Taurians from ''Manga/OutlawStar''.

* The alien Badoon and Skrulls and Snarks of Creator/MarvelComics. Marvel also has the Serpent Men, borrowed from ''ComicBook/{{Conan|TheBarbarian}}'' in the days when he had a comic there. Ch'od of the Starjammers also fits the description (although he's basically a good guy). As does, to some degree, Stegron the Dinosaur Man. And the SpacePirate Captain Reptyl. And the Tribbitites, aka Toad Men. Along with assorted reptilian {{mutants}} such as Slither, Scaleface, Primal, etc. Basically, Marvel likes this trope.
** ComicBook/TheUltimates has the Chitauri, who are a DarkerAndEdgier reimagining of the Skrulls.

* Clonezone the Hilariator from ''Comicbooks/{{Nexus}}.''

* The {{Primortals}}, being descended from different ancient Earth animals, include reptilian races, most notably Zeerus's pterodactyl people.

* Many sentient ''Franchise/StarWars'' races, most notably the Trandoshans. ''Film/AttackOfTheClones'' also features [[http://starwars.wikia.com/wiki/Zam_Wesell Zam Wesell]], the shapeshifting Clawdite assassin hired to kill Senator Amidala.
* The Zorgons in the film/book ''Film/{{Zathura}}''.
* Grig from ''Film/TheLastStarfighter,'' though he's actually a nice guy.
* General Sarris and his people in ''Film/GalaxyQuest'' are members of an unnamed reptilian race.
* The Chitauri of ''Film/{{The Avengers|2012}}'' are portrayed as these.

* The villains in the Literature/JasonWood story "Viewed in a Harsh Light".

* The Race from ''Literature/{{Worldwar}}'' is a race of reptilians whose strong sense of cultural pride drives them to try and conquer Earth. The two species (Rabotevs and Halessi, though that is probably the Race's name for them) they subjugated before invading Earth were apparently also reptilian in nature, as they are mentioned as being fairly similar to the Race.
** In ''Homeward Bound'', humans finally meet members of the two other species after reaching Home, although they claim to have already seen pictures of them. This is also the first description of the races that the readers get. The Rabotevs, for example, have two thumbs on each hand and feature eye stalks instead of eye turrets. The Halessi look more like cross between LittleGreenMen and lizards, being small, squeaky-voiced, and more erect than members of the Race, also featuring smaller snouts. Unlike the Race, the Rabotevs and the Halessi don't suffer narcotic or mating-inducing effects from ginger.

* David Brin's Uplift Series has a few Reptillians but two stand out:

* H. Beam Piper messed with this trope in ''Uller Uprising''. When the reptilian Ullerians fight against the humans on Uller, some forces side with the humans. The story was a retelling of the Sepoy Mutiny In Space, with the humans as the British, so FridgeLogic gets a workout.
** The people of Uller, good and bad, are multi-dimensional and complex, with several different cultures.

* ''Invoked'' by the Pervects of the ''Literature/MythAdventures'' series, who are green-scaled, sharp-toothed humanoids from the dimension Perv. Although they look the part, most ''actual'' Pervects aren't so much evil as rude, pushy, and egotistical; their racial reputation for being decadent, cruel and bloodthirsty is mostly propaganda, disseminated by the Pervects themselves to discourage non-Pervect freeloaders from immigrating to their wealthier, more advanced dimension.

* The Visitors from ''Series/{{V 1983}}'' are the {{Trope Codifier}}s. They infiltrate many parts of human society, and they want to ''[[ToServeMan eat us]]'' (along with other tasty mammals). Rather than shapeshifting, however, they use fake human-like skin to mask their true appearance, a method best exemplified by the iconic shot of Diana peeling back the skin on one side of her face to reveal green scaly skin and a catlike eye.

There are also the Ice Warriors, the inhabitants of Mars, though their reptilian features aren't emphasized as much.
** We also have the Slitheen, a clan of Raxacoricofallapatorians who invade Earth, kill human government officials, and wear their skins to infiltrate our society.

* The Sleestak from ''Series/LandOfTheLost''.
** And the Altrusians, who even though they are the ancestors of Sleestak are different both physically (shorter, stockier with an extra finger) and mentally (far more intelligent) enough to qualify as a separate race.
* The extremely brutal Scarrans of ''Series/{{Farscape}}'', who create one of the two [[TheEmpire evil empires]] of the show. The one HalfHumanHybrid we see of them is also a vicious ManipulativeBastard.
** He also requires technology to survive (cooling rods in the brain that have to be replaced regularly), as his reptilian half craves heat, while his HumanAlien half can't stand it.

[[folder: TabletopGames]]
* ''TabletopGame/{{Space 1889}}'' has the lizard men of Mars. They are not evil or sadistic though.
* Among the various SnakePeople, LizardFolk, and {{Draconic Humanoid}}s in ''TabletopGame/DungeonsAndDragons'', the serpentine yuan-ti stand out as this trope due to their penchant for sending "purebloods" (low-ranking individuals who look mostly human) into human society as spies. Meanwhile, the spinoff ''TabletopGame/{{Pathfinder}}'' has Reptoids, a race of shapeshifting infiltrators from another planet or dimension (they refuse to divulge their origins even under duress, so it is somewhat unclear) who seek to prepare the target world for invasion.

* You can get these in ''VideoGame/SimEarth'' if Dinosaurs or Reptiles become sentient.

* [[AncientAstronauts The Watchers]] from ''VideoGame/DarkVoid'' are manipulative shapeshifting reptilians exiled into AnotherDimension by early humans. In keeping with this trope, their [[BizarreAlienBiology life cycle]] is based on metamorphosis: they emerge from the egg as larval, wormlike hatchlings, and they pilot PoweredArmor suits as basic mooks. As they get older and more intelligent, they grow arms and legs and become more snake-like; they also get to pilot something like an alien HumongousMecha. Finally, the Elder form is the most intelligent, and can shapeshift to perfectly mimic a human appearance. These serve as spies in human society and leaders for the rest of the species.

* The Sakkra, from the ''VideoGame/MasterOfOrion'' series.
* The turn-based strategy ''VideoGame/SpaceEmpires 4'' has red lizard-people with vaguely [[Franchise/StarTrek Starfleet-esque]] ship designs as one of the possible appearances for your chosen empire.
** They are included in ''Space Empires 5'' as well, for which they decorated the cover, and originated in the third game of the series. Called the Jraenar in all games.

* The Vesk of ''TabletopGame/{{Starfinder}}'', a ProudWarriorRace who control the Veskarium and have formed an uneasy alliance with the Pact Worlds.
* ''TabletopGame/YuGiOh'': The [[http://yugioh.wikia.com/wiki/Alien Alien]] archetype. Most of the members have some sort of lizard-like attributes to them, and they are all Reptile-type. They aren't exactly portrayed in a good light either, considering their card artworks depict things like [[http://yugioh.wikia.com/wiki/Brainwashing_Beam brainwashing]], [[http://yugioh.wikia.com/wiki/%22A%22_Cell_Recombination_Device experimentation]], and [[http://yugioh.wikia.com/wiki/Planet_Pollutant_Virus planetary invasion.]]

* The krogan and the drell in the ''Franchise/MassEffect'' franchise. The former are hulking, dinosaur-style [[ProudWarriorRaceGuy warrior-race-guys]], while the latter are more humanoid (but still scaly) and specifically built to be MrFanservice.
** According to Javik in ''VideoGame/MassEffect3'', the salarians were essentially frogs back in his time.
-->'''Javik:''' The lizard people evolved?
-->'''Liara:''' I believe they're amphibious.
-->'''Javik:''' They used to eat flies.

* ''WesternAnimation/StevenUniverse'': In "Keep Beach City Weird", it's revealed that [[ConspiracyTheorist Ronaldo]] blames all the crazy happenings in town on snake people, or "sneople", who secretly control the world. He's initially disappointed to find out it's all because of the Gems (to whom the citizens of Beach City are FantasticallyIndifferent), but at the end of the episode Ronaldo is inspired to make up a ([[TheCuckoolanderWasRight surprisingly accurate]]) conspiracy theory about "polymorphic sentient rocks".

* Within the early {{fantasy}} genre, one very unique forerunner of this trope is the Green Lady, Creator/CSLewis's central villain in ''Literature/TheSilverChair'' (the fourth ''[[Literature/TheChroniclesOfNarnia Narnia]]'' book published, and the sixth in terms of InUniverse chronology). From within her ElaborateUndergroundBase, the Lady subtly acquires power through governmental infiltration and mind control, and she alternates between a regular human form and a ScaledUp form. Of course, since TheReptilians largely remained an UnbuiltTrope back in TheFifties, the Lady bears many differences from this trope as we know it today. For example, her reptilian form isn't humanoid like most examples today, but rather a massive venomous snake. Also, instead of TheReptilians being a whole species of invaders, the Lady is the only example that we see. [[DiabolusExNihilo Lewis never reveals her origins]] beyond vaguely hinting that she could be somehow connected to the White Witch from ''Literature/TheLionTheWitchAndTheWardrobe'', nor does he specify whether her original form is humanoid, reptilian, or something else entirely.

* Renowned CloudCuckooLander Creator/DavidIcke is the most prominent advocate of the idea that Reptilians are real. He claims that they come from the Alpha [[MeaningfulName Draconis]] star system, and that UsefulNotes/GeorgeWBush, Elizabeth II, and many other world leaders are among their ranks.
** Website/AboveTopSecret, a large conspiracy site, is a good source for people who actually believe these creatures exist and are behind global conspiracies.

* The obscure XBOX shooter ''VideoGame/BruteForce'' has Brutus, a "Feral" (a scaly green lizard man with a voice like [[InspectorGadget Doctor Claw]]) as one of the main PlayerCharacters. He's by far the toughest squad member, and sports a HealingFactor and AuraVision.

* The Reptoids in ''Film/TheAdventuresOfBuckarooBanzaiAcrossTheEighthDimension'', though they're not evil as an specie, the bad guys in the movie are rogue criminals hated by their own government because of their FantasticRacism.

* In ''WesternAnimation/{{Futurama}}'', the Pope is one in reference to the infamous conspiracies of world leaders being Reptilians, although he's much less humanoid (more like an anthropomorphic lizard) than conspiracy theorists portray. The difference is the fact that the Pope is a lizard-like alien is obvious to everyone, to the point where it's used in a variation of [[IsTheAnswerToThisQuestionYes "Is the Pope Catholic?"]] A couple other Reptilians appear as background characters in some episodes.

* ''WesternAnimation/StevenUniverse'': In "Keep Beach City Weird", it's revealed that [[ConspiracyTheorist Ronaldo]] blames all the crazy happenings in town on snake people, or "sneople", who secretly control the world. He's initially disappointed to find out it all's because of the Gems (to whom the citizens of Beach City are FantasticallyIndifferent), but at the end of the episode Ronaldo is inspired to make up a ([[TheCuckoolanderWasRight surprisingly accurate]]) conspiracy theory about "polymorphic sentient rocks".

* An episode of ''WesternAnimation/StevenUniverse'' had the title character dress up as one to please ConspiracyTheorist Ronaldo, though they're referred as snake-people (or sneople).

* GoldenAge [[{{Shazam}} Captain Marvel]] comics had Mr. Mind's alien flunkies, the Crocodile Men from Planet Punkus.

* The Aandrisk in Literature/TheLongWayToASmallAngryPlanet look like human sized bipedal lizards with multicolored feathers on their heads.
* Several are seen throughout ''Literature/AlmostNight''. They have green scales and never wear shirts. A row red spikes go down their back. They're not universally good or evil.

* The Race from ''Literature/{{Worldwar}}'' is a race of reptilians whose strong sense of cultural pride drive them to try and conquer Earth. The two species (Rabotevs and Halessi, though that is probably the Race's name for them) they subjugated before invading Earth were apparently also reptilian in nature, as they are mentioned as being fairly similar to the Race.

Unlike the Race, the Rabotevs and the Halessi don't suffer narcotic or mating-inducing effects from ginger.

* A Series/StarTrekTheOriginalSeries novel - ''The Captain's Table: War Dragons''- had the humanoid reptillian Anjiri and the theropod-like Nykkus [[spoiler: which turn out to be [[BizarreAlienBiology two forms of the same species]].]] While their dialogue does not use SssssnakeTalk, their language relies so heavily on gestures that {{Universal Translator}}s can't handle it. While the first ones to show up are basically incompetent SpacePirates, it turns out that neither of these traits [[PlanetOfHats is their hat]].

* The Yilani of Creator/HarryHarrison's ''Literature/WestOfEden'' series are a race of humanoid reptilians that evolved on an Earth where the dinosaurs never died out. The first book spends much of it's first portion with them and we get a very detailed look at their world. They are semi-aquatic (they are related to seagoing lizards), have a matriarchal society thanks largely to their borderline BizarreSexualDimorphism, and have mastered biotechnology on a staggering scale; their cities are literally alive. Oh, and once the humans enter the picture in a significant way, they immediately become the {{Card Carrying Villain}}s of the book because {{humans|AreSpecial}} are [[MostWritersAreHuman awesome]] and reptiles... [[ReptilesAreAbhorrent well duh]]. It's awkward.

** The Soro are imperialistic, cruel and war. And to be expected, enemies of Earth Clan
** The Thennannin are also reptiles. They are incredibly conservative, self righteous and dogmatic. However they are not actually evil. In the Second Novel, Star Tide Rising, they are fighting Humans along with everyone else to get the big secret they think the Streaker is carrying. By the third novel they have "adopted" [[spoiler:Gorillas]] as as a client species and are dutifully helping protect Earth.

* In the SpeculativeDocumentary book ''All Tomorrows'' by Nemo Ramjet one of the descendants of mankind is a race known as the Saurosapients, which evolved from large lizards brought to a tropical planet by humans. Ironically they were once the livestock of an unintelligent species of genetically modified human that became ''their'' livestock after reptiles took over. They're not evil nor very human-like in general appearance (more like featherless raptors), but their society grows paranoid that an alien race will wipe them out like the humans before them. [[spoiler: It's presumed that robot humans did wipe them out along wih many other races]].

* Within the early {{fantasy}} genre, one very unique forerunner of this trope is the Green Lady, Creator/CSLewis's central villain in ''Literature/TheSilverChair'' (the fourth ''[[Literature/TheChroniclesOfNarnia Narnia]]'' book published, and the sixth in terms of InUniverse chronology).
