The Reptilians are one of the stock Humanoid Aliens, sporting reptile-like features and popping up frequently in Science Fiction and abduction stories. They share quite a few similarities with Little Green Men and The Greys in terms of appearance (human-like, large eyes, baldness, strange skin) and modus operandi (abduction, invasion), but they have enough unique features to set themselves apart. Since they are reptiles they, of course, are almost always evil. Unlike their Grey and Green cousins, though, The Reptilians tend to be portrayed as even more vicious and sadistic, often abducting humans as a Slave Race or as a food source. They are frequently shape-shifters, changing into human form in order to infiltrate our ranks and take over the world before we even realize it. Sometimes, like Little Green Men and The Greys, 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 Scary Dogmatic Aliens or as the vanguard of a vast but decadent empire. They commonly have hidden bases Beneath the Earth, which probably stems from a fusion of the Primal Fears of both reptiles and the underground. Oftentimes, they are mentioned as having created The Greys (by cloning) as a Slave Race, until some decided to rebel, thus necessitating the Greys to 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 moved elsewhere among the stars, not necessarily in that order.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 Velociraptor or Tyrannosaurus rex (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 stalled out before mammals could take their rightful place at the top. Depending on just how reptilian the Reptilians are portrayed to be (and depending on a program's budget), they can run the gamut from bald humans with weird eyes to full-on Lizard Folk with a human-like gait. They usually have a hatred or disgust for all mammals. It is common for Reptilians to insult humans by referring to them as "apes". Also, a rule of thumb to keep in mind is that the more reptilian the aliens are, the less likely they are to be portrayed as good guys, in line with Reptiles Are Abhorrent; sympathetic Reptilians are more likely to have Non-Mammal Mammaries, among other things. Compare Lizard Folk and Snake People, which are generally the Fantasy Counterparts to this trope. The former also tend to be more like dumb scaly orcs in contrast to the advanced Reptilians.

Anime & Manga
- The Dinosaur Empire form Getter Robo are composed of Lizard Folk Mooks, with several humanoid, scaled generals with a variety of dinosaur features.
- Daibazaal/Zarkon in GoLion/Voltron has slitted eyes, scales on his body, and finned ears. Several other residents of Planet Galra/Doom have similar appearances.
- Taurians from Outlaw Star.
- One of the Doraemon movies deal with The Reptilians whose civilization thrives Beneath the Earth, and seek to alter the timeline so it's them, not the humans, who flourish above ground. Despite their sinister motives, they are actually no less moral than humans, if not objectively better (their technology being far more eco-friendly, for example). The finale of the movie has them agree to stay under the earth, because Doraemon's future gadgets saved their ancestors from extinction.
- The alien Badoon and Skrulls and Snarks of Marvel Comics. Marvel also has the Serpent Men, borrowed from Conan 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 Space Pirate Captain Reptyl. And the Tribbitites, aka Toad Men. Along with assorted reptilian mutants such as Slither, Scaleface, Primal, etc. Basically, Marvel likes this trope.
- The Lizarkons of the planet Thanagar, Hawkman's homeworld, in DC Comics. Also the Gordanians and Psions, who both terrorize Starfire's home system of Vega.
- Clonezone the Hilariator from Nexus.
- Golden Age Captain Marvel comics had Mr. Mind's alien flunkies, the Crocodile Men from Planet Punkus.
- Judge Dredd had the Kleggs, thuggish and dim crocodile-like mercenaries who accept payment in meat.
- The Primortals, being descended from different ancient Earth animals, include reptilian races, most notably Zeerus's pterodactyl people.
- The Venn species from Reyn are basically bipedal salamanders, albeit rough sketches indicated that they originally were going to look different.
- Many sentient Star Wars races, most notably the Trandoshans. Attack of the Clones also features Zam Wesell, the shapeshifting Clawdite assassin hired to kill Senator Amidala.
- The Zorgons in the film/book Zathura.
- Grig from The Last Starfighter, though he's actually a nice guy.
- General Sarris and his people in Galaxy Quest are members of an unnamed reptilian race.
- The Chitauri of The Avengers are portrayed as these.
- In the Super Mario Bros. film, any Dinohattan inhabitant put into President Koopa's Devolution Device gets turned into a Goomba, a type of Reptilian with a tiny head that can resemble a velociraptor, a scaly ape, or a snake. They're more unintelligent goons than truly evil, and one Goomba devolved from Toad actively helps Daisy and the Mario Bros.
- The Drac from Enemy Mine, though the movie's main point is that they're not really the bad guys, and humans aren't really the good guys either.
- The "Predator" alien in Code Red: the Rubicon Conspiracy is one of these under his (its?) mask.
- The Reptoids in The Adventures of Buckaroo Banzai Across the 8th Dimension, 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 Fantastic Racism.
- The Aandrisk in The Long Way To A Small Angry Planet look like human sized bipedal lizards with multicolored feathers on their heads.
- Several are seen throughout Almost Night. They have green scales and never wear shirts. A row red spikes go down their back. They're not universally good or evil.
- The villains in the Jason Wood story "Viewed in a Harsh Light".
- Marion Zimmer Bradley's The Brass Dragon. The Dikri are a race of cold, ruthless dragon-like aliens who can Shape Shift into human form. They act as renegades, interfering on primitive worlds in violation of interstellar rules.
- The Race from 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.
- In Homeward Bound, humans finally meet members of the two other species after reaching Home, althogh 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 Little Green Men 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.
- Edgar Rice Burroughs created the Horibs for his Pellucidar series. Pellucidar also has the telepathic Giant Flyer race, the Mahar, descended from pterosaurs.
- The Viis, the main antagonists of Deborah Chester's The Alien Chronicles novels, are decadent, humanoid, frilled lizards.
- The AAnn in Alan Dean Foster's Humanx Commonwealth universe. Lighter and weaker than humans but much faster with sharp claws and teeth. Almost Always the antagonist when they appear. Includes Sssssnake Talk. They also communicate with hand gestures to show emotion, although this is a common linguistic trait in that universe. There have been several sympathetic AAnn characters in the Flinx setting, even one that fell in love with the titular redhead. None outlast the book they are introduced in.
- Andre Norton's Science Fiction novels in the Council/Confederation universe feature the Zacathans, a race of Reptilians whose "hat" is archaeology and history. They live at least a thousand years on average. Their names all begin with "Z".
- Android at Arms: When examining the facility in which they had been imprisoned, the protagonists find plans for building a Ridiculously Zacathan Robot duplicate of an unknown Zacathan.
- Brother to Shadows: The protagonist works with a Zacathan for an extended period, one of the best glimpses of them that we get.
- Uncharted Stars: The protagonists hook up with a Zacathan archaeologist in the endgame, since they have a common objective: to find the Precursors' source of the zero stones.
- The X Factor: The head of the dig on Mimir is Zacathan.
- Star Rangers (alternate title The Last Planet): The hero's best friend is a Zacathan, a fellow member of their reconnaissance team. Although highly intelligent and knowledgeable, he's somewhat less science-oriented than most Zacathan portrayals. He's also more ready to fight than most, and mentions that his brother is highly skilled with a force blade. "Zippp—and there's an enemy down with half his insides gone—"
- The Quintaglios of Robert J. Sawyer's Quintaglio Ascension trilogy are the descendants of small Tyrannosaurs. Since the series focuses on an important period of their planet's history, we get a characterization of them that is far more nuanced than usual.
- A Star Trek: The Original Series novel - The Captain's Table: War Dragons- had the humanoid reptillian Anjiri and the theropod-like Nykkus which turn out to be two forms of the same species. While their dialogue does not use Sssssnake Talk, their language relies so heavily on gestures that Universal Translators can't handle it. While the first ones to show up are basically incompetent Space Pirates, it turns out that neither of these traits is their hat.
- The Gnalish in the Star Trek Novel Verse are a rare example of a benevolent, heroic Reptilian race. Okay, they're still grumpy and sour, but at least they're friendly.
- Lisanne Norman's Sholan Alliance series has the antagonist species, the Valtegans with no tail, and the friendly Sumaan with a very strong thick tail.
- Ssilissa of the Larklight trilogy; blue, scaly, with spines for hair and a heavily clubbed tail. Is noted occasionally for averting Non-Mammal Mammaries (and thus not fitting into dresses cut for humans), and has a few self-image issues on account of being raised by humans. In the third book, we meet her race, the Snilth, a matriarchal Proud Warrior Race who serve as mooks for the book's Big Bad. They live in clans identified by the shape of the weapon on their tails, and Ssil's proves her to be the only known heir to the banished queen who turned against the Big Bad long ago.
- The Ternaui in The Excalibur Alternative. Initially appearing as silent bodyguards to the Big Bad, it turns out that they are telepathic and detest their slavery. Eventually they side with the humans.
- The Yilani of Harry Harrison's West of Eden 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 Bizarre Sexual Dimorphism, 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 Villains of the book because humans are awesome and reptiles... well duh. It's awkward.
- Poul Anderson's Merseians, although usually at odds with humanity, are a more nuanced portrayal (and have a culture based off of the Sassanid Empire).
- David Brin's Uplift Series has a few Reptillians but two stand out:
- 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" Gorillas as as a client species and are dutifully helping protect Earth.
- 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 Fridge Logic gets a workout.
- The people of Uller, good and bad, are multi-dimensional and complex, with several different cultures.
- In the Speculative Documentary 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. It's presumed that robot humans did wipe them out along wih many other races.
- In Andre Norton's Storm Over Warlock, the native species is reptilian, vaguely draconic, whence their name Wyverns. They manage to look good. And doubtlessly benefit from the contrast with the Insectoid Aliens Planet Looters, the Throg.
- The Perry Rhodan universe naturally features its share of reptilian aliens all the way back to the Topsiders (Topsidians? Well, Topsid — without an 'e' — is what their homeworld is called in any event) who in some of the earliest issues failed to invade Earth and instead hit the Vega system only due to a navigational error. If there's a general stereotype associated with intelligent reptiles in this series, it's a notional tendency to be more coldly rational than "hot-blooded" mammalian lifeforms; beyond that they tend to get treated as simply people like everybody else.
- In the science fiction novel Nation of the Third Eye by K.K. Savage, there is the reptilian race of Draconians. They live in a higher astral dimension but can also enter physicality at will. Needless to say, they are among the bad guys.
- H.P. Lovecraft'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 Venusians in Kenneth J. Sterling's and H.P. Lovecraft's short story In the Walls of Eryx are describe as reptilian.
- The very bestial-looking Hork-Bajir from the Animorphs series are a highly atypical example. They make up a large portion of the evil 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 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.
- Invoked by the Pervects of the Myth Adventures 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.
- Within the early fantasy genre, one very unique forerunner of this trope is the Green Lady, C. S. Lewis's central villain in The Silver Chair (the fourth Narnia book published, and the sixth in terms of In-Universe chronology). From within her Elaborate Underground Base, the Lady subtly acquires power through governmental infiltration and mind control, and she alternates between a regular human form and a Scaled Up form. Of course, since The Reptilians largely remained an Unbuilt Trope back in The '50s, 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 The Reptilians being a whole species of invaders, the Lady is the only example that we see. Lewis never reveals her origins, nor does he specify whether her original form is humanoid, reptilian, or something else entirely.
- The Visitors from V (1983) are the Trope Codifiers. They infiltrate many parts of human society, and they want to 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 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.
- The V (2009) reboot series took no motion to change any of this. Except the Visitors were more of a combination of 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 interbreeding between humans and Vs.
- In War of the Worlds, the Martians are essentially turned into the aforementioned Visitors. Except that they're body snatchers.
- Doctor Who:
- The Silurians and their aquatic cousins the Sea Devilsnote . 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.
- We also have the Slitheen, a clan of Raxacoricofallapatorians who invade Earth, kill human government officials, and wear their skins to infiltrate our society.
- Star Trek:
- The Gorn. Most famously one had a duel with Kirk in the original series. In other media they've been more neutral, or in Star Trek: Starfleet Command they're actually allies of The Federation
- The rarely-seen brandy-making Saurians.
- The Cardassians. Though they're the least reptilian, looking pretty much like humans with scales tacked on, they also happen to be the most villainous of the reptoid lot.
- The Reptilian Xindi in Star Trek: Enterprise.
- The Voth were descended from Earth hadrosaurs. Which is at least a new one, as far as Dinosauroids go.
- The Hirogen and the Jem'Hadar also at least look the part, and are the villains in most of their appearances.
- The Sleestak from Land of the Lost.
- 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 Farscape, who create one of the two evil empires of the show. The one Half-Human Hybrid we see of them is also a vicious Manipulative Bastard.
- 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 Human Alien half can't stand it.
- The Drazi, along with other less significant species, in Babylon 5, although their Proud Warrior Race personalities are a bit different from the metaphorically cold-blooded norm, and were not hostile to Humans (during the 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 Wave Motion Gun 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 until Ivanova inadvertently forces them to stop.
- One episode of Buck Rogers in the 25th Century involved Reptilian aliens disguised as humans. Buck exposed them by lowering the temperature. Being cold-blooded, they collapsed.
- 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.
- Space 1889 has the lizard men of Mars. They are not evil or sadistic though.
- The Yuan-ti in Dungeons & Dragons are are more snake than lizard, but in addition to giant snakes with arms, their race also includes some individuals that are almost indistinguishable from humans. Those are usually send to infiltrate human society and use their telepathic powers to usurp the local government.
- D&D also has Lizard Men, Kobolds, Troglodytes, Draconians, Dragonborn, Saurials, Bullywugs, Slaad, Tortles, Babblers, and countless other variants.
- Pathfinder carries over most of the ones mentioned above that aren't under trademark. They also have Reptoids, who draw upon traits more specific to this trope, like being 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.
- The Ithklur in Traveller are a Proud Warrior Race that serves as soldiers to the Hivers (who need them badly being rather courage-deprived as a rule). The Ithklur are not evil but are hearty souls that love a good fight.
- Exalted has some snake-beastmen, including at least one who Exalted. It also has the dinosauroid Dragon Kings, who predate humanity and are almost extinct in the current day.
- Infinite Worlds for the 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.)
- You can get these in SimEarth if Dinosaurs or Reptiles become sentient.
- Deis/Bleu in the Breath of Fire series is one of these. She would be a snake person, but her entry in Breath of Fire IV shows her to be a shapeshifter goddess, so she falls into this category as well as Snake People. She is also a rare heroic example, if a bit of The Hedonist.
- The snake-talking Thrynn in Starflight. Interstellar merchants and con-artists who, despite their depiction as having purely carnivorous dental structure, find themselves in constant war with their neighbors, the Elowan. The Thrynn have a taste for Elowan "headfruit" you see. Despite this habit, they are generally peaceful with other races, and selling plutonium to them can be highly profitable—unless you have an Elowan aboard, that is.
- The krogan and the drell in the Mass Effect franchise. The former are hulking, dinosaur-style warrior-race-guys, while the latter are more humanoid (but still scaly) and specifically built to be Mr. Fanservice.
Javik: The lizard people evolved?Liara: I believe they're amphibious.Javik: They used to eat flies.
- According to Javik in Mass Effect 3, the salarians were essentially frogs back in his time.
- The turians (in this case, Space Romans) remind some humans of the link between dinosaurs and birds.
- Unusually, none of the quasi-reptilian species from Mass Effect are portrayed as evil. The krogan tend to be aggressive, warlike, and are frequently antagonists from shady mercenary gangs and the like, but two party members from the series are krogan and the species shows strong signs of moving beyond its violent past. The turians attacked the first humans they encountered, but this was because of a misunderstanding. The drell overindustrialized and destroyed the ecosystem of their planet, but they are now the devoted servants of the gentle, mystical hanar. The salarians have lots of....ethically questionable scientists, but overall they are portrayed positively.
- The Watchers from Dark Void are manipulative shapeshifting reptilians exiled into Another Dimension by early humans. In keeping with this trope, their life cycle is based on metamorphosis: they emerge from the egg as larval, wormlike hatchlings, and they pilot Powered Armor 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 Humongous Mecha. 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 Cardianon in Star Ocean: The Last Hope. Originally a primitive race, the Grigori accelerated their evolution, and provided them with knowledge that led to them becoming one of the most technologically advanced races in the universe in a very short span of time, but also turned them into a bunch of fanatical planet conquerors. They look like somewhat reptilian humanoids in the lowest stage of evolution they're seen in, but their more advanced forms are traditional lizardmen, then dragonmen, and lastly, full fledged dragons.
- The Tarka from Sword of the Stars evolved from lizards but are very human-like, resembling scaled apes◊ more than actual lizards. They are a highly civilized and pragmatic warrior race whose empire is a few thousand years older than human civilization, and are presented as sympathetic if fairly machiavellian, warlike, and prone to picking on those weaker than themselves.
- The Sakkra, from the Master of Orion series.
- The turn-based strategy Space Empires 4 has red lizard-people with vaguely 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.
- Traffic Department 2192 has the Selarian species, and their representative in Vulthaven's TD, Lieutenant Junior Grade Koth. If he's any indication, their species hisses their S's.
- The obscure XBOX shooter Brute Force has Brutus, a "Feral" (a scaly green lizard man with a voice like Doctor Claw) as one of the main Player Characters. He's by far the toughest squad member, and sports a Healing Factor and Aura Vision.
- The Reptites in Chrono Trigger, who were the pinnacle of dinosaur evolution in 65 million BC. They oppressed the caveman population until Lavos landed. In an alternate timeline in Chrono Cross, they evolved into dragons.
- The Skedar from Perfect Dark bear some similarities to the Reptilians, being bipedal, dinosaur-like creatures who masquerade as Scandinavian men. Their offspring resemble tiny, vicious lizards.
- The Teladi from the X-Universe series are a humanoid reptilian race whose aspect of life is entirely motivated by money. Their society is comprised of a Mega Corp. which dominates their politics and businesses, and their government is essentially a corporate republic. Because of their reptilian nature, the Teladi have a... tendency to speak with an accent that emphasizes the letter s in such a way that it becomes memetic. They tend to be neutral to all the other factions, even the Space Pirates. Because of this last note, it's not surprising to see some factories produce a fancy drug known as Space Weed, which is basically the series' version of marijuana IN SPACE! This drug is considered contraband in any sector that isn't Teladi or Pirate-owned, and often is a popular source of income to would-be smugglers.
- In ZombiU, The Prepper seriously believes that the Queen is one of them.
- The Snakemen in X-COM: UFO Defense are human-sized snake-like aliens with rapid reproduction times and appear about midway through the game. In XCOM: Enemy Unknown, the Thin Men are a reptilian species that have been genetically-modified to resemble humans in order to serve as infiltration units. XCOM 2 wheeled out the Vipers, a race of sexy lady snakes, the Thin Men's true form.
- When they don't resemble Insectoid Aliens, the Space Pirates occasionally have elements of this, particularly in the first Metroid Prime. This may be tied into the fact that two of their leaders, Ridley and Kraid, are both very reptilian, being a dragon and a Godzilla-like Kaiju respectively (at least since Super Metroid; the very first game had concept art portraying Ridley as some weird multi-eyed bug creature and Kraid as having fur).
- Metroid Prime 3: Corruption has the Multi-Armed and Dangerous Reptilicus of Bryyo, one of the more atypical examples of this trope. Once known as the intelligent Bryyonians, with enough clout to have extensive contact with the Chozo, a brutal conflict between the tech-using Lords of Science and the magic-using Primals devastated the planet. The point of no return came when the Leviathan Seed crashed into the planet and spread Phazon everywhere, after which the Bryyonians degenerated into savage beasts.
- The Draske in Starbase Orion are small, winged reptiles whose natural flight ability makes them superior pilots and navigators. According to their backstory, they are not warlike and haven't had to fight anyone in the thousands of years they have been exploring space (mostly using sublight ships). They are extremely long-lived (their lifespans are measured in thousands of years) and are ruled by Matriarchs. Every year, many Draske participate in tournaments. The victors experience a great boost in their careers. Those who lose the tournaments three times typically commit suicide to spare their families the shame. The Draske Hegemony incorporates several other races as client members, including the Harge and the Felinoids. The reason they're on part with the other races in the game is mostly due to them being unaccustomed to warfare.
- The Ma-non of Xenoblade Chronicles X are a highly nonstandard example. Essentially resembling short Gungans with more reptile-like scutes and ridges, their highly technology-dependent culture means that nearly every single one is a Brilliant, but Lazy Manchild who prefers to spend time eating pizza rather than putting effort into building and maintaining New LA. They're as chipper and trusting as can be, always excitedly asking questions about their new human and Nopon friends and never assuming maliciousness from anyone (Ackwar of the Mediators is an exception, as his familiarity with the cultures and mindsets of humans and other xenos makes him far less naive when it comes to his detective work). The "reptilian" part only ever explicitly comes up with a prejudiced shopkeeper who doesn't want to interact with the Ma-non due to her preexisting anxiety around reptiles from Earth; with some coaxing from the player, she can be convinced that they're nicer aliens than she is initially willing to give them credit for.
- From Battleborn:
- Pendles is an adolescent Roa, a type of anthropomorphic snake alien species which spend a part of their lives as bipedal creatures before eventually shedding their limbs and return to living beneath the waves. He put a stop to his natural molting process via hormone therapy after his right snake tail-like tentacle fell off.
- A couple of skins for the other Battleborn turn them into reptilians. Whiskey Foxtrot's "It's Reptile Foxtrot!" skin turns him into a reptile scaled version of his normal self. Meanwhile, Ernest's appropriately named "Devolved" skin basically devolves the bird man back into a feathered dino man.
- Stellaris has "reptilian" as a category of species (along with stuff like "avian", "mammalian" or "fungoid"). There's an achievement for doing the "alien infiltration" ploy on a pre-FTL reptilian species with a human empire, and the achievement's symbol is a reversed "V".
- Legrakix is a morbidly obese version of this trope, though he isn't evil. Unless eating everybody's lunch at work is evil.
- The Reptoids in Trying Human can be divided into two main subspecies: Draconian and Terran Reptoids. The long-tailed Terran Reptoids evolved from Troodon dinosaurs and were uplifted by the winged Draconian Reptoids, making them forever indebted to their benefactors. Both sub-races are capable of shape-shifting and enjoy eating meat, including human.
- In Earthsong, one of the ill-fated Guards in Earthsong's welcoming party for Beluosus is a Reptilian.
- Reptilis Rex is centered around the "Reptoids" being forced to move to the surface and reveal themselves to mankind, which treats them like second class citizens. They can't shapeshift per se but own shapeshifting pets which they can wear as masks, hence there have been an unknown number of Reptoid infiltrators throughout history including Barack Obama and Mitt Romney.
- They make a brief appearance in Rasputin Barxotka, with their planned invasion of Earth thwarted by the strip's version of The Greys.
- From El Chigüire Bipolar: Maduro: "The irresponsible opposition hasn't spoken against the murderous alien lizards."
- Lizard People Of New York parodies the popular photoblog Humans Of New York by re-captioning the photos of humans into portraits of shape-shifting Reptilians.
- The Raptors from The Storm Hawks. They're all irredeemably evil except for Leugey, who's too stupid to be anything but a bad guy.
- ThunderCats (2011) has Third Earth's Lizards, overlapping with Lizard Folk. They're adversaries to the Thundercats, a rare deconstructed example of Reptiles Are Abhorrent, reacting to generations of oppression and Fantastic Racism at the hands of the Cats. Some are decent, pulling an Androcles' Lion in return for a Cat's uncharacteristic display of altruism.
- Bravestarr has a race of Snake People, including villainess Vipra and good guy Handlebar who had a mustache.
- The Triceratons, essentially Proud Warrior Race anthropomorphic ceratopsians, from Teenage Mutant Ninja Turtles.
- The truly strange The Mighty Ducks cartoon had a straight-up evil race made up of anthropomorphic ceratopsians, along with more conventional lizard-people types. And really, if the aforementioned Triceratons, Voth, and especially the Quintaglios are all "reptiles", then it isn't fair not to mention the titular duck-people.
- One of the Rulon subraces on Dino-Riders was a race of Snake People.
- An episode of Steven Universe had the title character dress up as one to please Conspiracy Theorist Ronaldo, though they're referred as snake-people (or sneople).
- The inhabitants of Planet Bone in Shadow Raiders are also reptilian.
- In 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 "Is the Pope Catholic?" A couple other Reptilians appear as background characters in some episodes.
- A race of iguana-like alien gangsters appear as antagonists in one episode of Men in Black.
- On Rocko's Modern Life, all the high-level executives at the World Domination bent Mega Corp. Conglom-O (including the CEO, Mr. Dupette) are lizards with a habit of picking their noses.
- The Martians in the 1962 Topps trading card series Mars Attacks looked like Little Green Men, only with skull-like faces and vaguely reptilian skin. When the cards were adapted for the 1996 Tim Burton movie, the production designers tried to make the Martians (according to Word of God) look like a cross between skeletons and snakes.
- Renowned Cloud Cuckoo Lander David Icke is the most prominent advocate of the idea that Reptilians are real. He claims that they come from the Alpha Draconis star system, and that George W. Bush, Elizabeth II, and many other world leaders are among their ranks.
- Above Top Secret, a large conspiracy site, is a good source for people who actually believe these creatures exist and are behind global conspiracies.
- In the early '80s, Dale Russell, curator of vertebrate fossils at the National Museum of Canada (now the Canadian Museum of Nature), proposed that, if the dinosaur genus Troodon hadn't died out, it could have evolved into a sentient humanoid creature, christened "Dinosauroid" by Russel. Since then, the Dinosauroid (in appearance vaguely resembling a scaly Grey alien) has been criticized as being implausible, because it is too anthropomorphic. Also, Science Marches On, and now we know that Troodon's appearance probably had more in common with birds than with reptiles. Thus, when paleontologist Darren Naish and artist Nemo Ramjet revisited the concept during The Noughties, the result was decidedly less humanoid◊ and veered into Bird People territory instead of this trope.
