History Main / OneGenderRace

* The Venusians met in ''Creator/AbbottAndCostello Go to Mars'' are all female, having banished the males and claiming to have perfected immortality. One or two small girls are seen, so it's possible that some form of procreation goes on.

* In ''Literature/{{Victoria}}'', [[LadyLand Azania]] is not yet there, but working hard to ''become'' this. Ruled by StrawFeminist ideologues, it has outlawed natural births, hoping to breed a new, all-female humanity through [[HomosexualReproduction eugenic cloning]].

* Used painfully (and {{deconstructed|Trope}}) in ''Literature/TheImmortals''. All 'Immortals' -- species which cannot die of old age or disease, but ''can'' be killed by physical or magical means -- are born in the Divine Realms as the product of human dreams or nightmares. One such species, the Tauros, is essentially a race of minotaurs who exist to rape and kill women. Daine, the protagonist of the story, asks the god of the 'duckmoles' (platypuses), if there even ''are'' any female Tauroses. When he says no, she gets angry and basically says 'well no wonder they attack human women all the time! That's all they know to do without women of their own who can handle it!' Broadfoot, the duckmole, muses that she's right, and 'Someone should consult the Greater Gods about this...' Later works reveal that the Greater Gods did examine it and found the trope was enforced: because Tauroses are born out of women's fear of rape, they will continue to exist as long as rape does and can only target human women.

* Snails, slugs and worms are all hermaphrodites; they do mate with others in order to reproduce but only one of the two can lay eggs.

* The clown fish essentially does the opposite. Fish are either sexually immature males, mature males or females with one mature male and one female living in a given population of clown fish. When a female dies, the mature male becomes the female and an immature male becomes the mature male (the female is always the largest and the mature male the second-largest). This means that by the time Nemo met his father in WesternAnimation/FindingNemo, he would have actually been his mother.

* Subverted with hyenas. Medieval scholars thought spotted hyenas were all male and reproduced [[HomosexualReproduction homosexually]]. This probably happened because females have enlarged clitorises that [[LadyLooksLikeADude look like penises]] before they give birth for the first time.

** The history of the Time Lords is, as with so many things, muddled. Technically, the second Gallifreyan we ever saw was female, although Susan wasn't even around when [[ContinuityDrift the concept of Time Lord even existed in the show]] -- the Doctor was AmbiguouslyHuman during her tenure, and she was only said to be Gallifreyan retroactively. For about a decade, all the Time Lords seen after the introduction of the concept were male; even the name implies this. Creator/TomBaker assumed the Time Lords were all male and purposely played his Doctor a little awkward around women to give the impression, with the Sisterhood of Karn even coming across as the Time Lords' DistaffCounterpart. However, 1970s ''Doctor Who'' was rather unclear as to whether "Time Lord" was the name of the race, or a title for members of the Chapters, which would make Tom's portrayal more of an unworldly Oxbridge don from the days when women weren't allowed on campus except as housekeeping staff. Regardless, the introduction of Romana in 1978 removed this assumption, and several Time Ladies have appeared since. In fact, with the Master becoming the Mistress (and the General in "[[Recap/DoctorWhoS35E12HellBent Hell Bent]]", and now Creator/JodieWhittaker) it has been established that Time Lords(/Ladies) can change sex when regenerating. So they're not so much a one-gender race as an all-genderfluid one.

* ''TabletopGame/{{Warhammer}}''/''TabletopGame/Warhammer40000'':
** The Orks in ''40k'' (and possibly the Orcs in the original ''Warhammer'') seem to be all ridiculously masculine, early [[RetCon non-canonical]] references to female Orks notwithstanding; however, since [=Wh40k=] Orks are actually a hybridization of mammal and ''fungus'' that reproduce via spores, attempting to assign a gender to them is an exercise in futility.
** ''TabletopGame/BloodBowl'' has [[http://www.games-workshop.com/gws/catalog/productDetail.jsp?catId=cat1290340&prodId=prod1560097 orc cheerleaders,]] which are female. Then again, ''Blood Bowl'' is essentially an alternate universe.

** Theoretically all Tyranids are this, as there is no documentation on exactly how they "reproduce" (The Norn Queens require biomass to create new creatures but doesn't seem to need anything resembling a male to actually spawn them). Things get weird when you realize that, due to their symbiotic weapons, they ''all'' technically qualify as females as their weapons spawn and gestate eggs, then spew them out via a muscle spasm.

** The Lizardmen in ''Warhammer'' are all males; they are born from spawning pools throughout Lustria, and were initially created by the Old Ones. Their war with the Skaven began when the Skaven poisoned one city's spawning pools.

* ''TabletopGame/WerewolfTheApocalypse'' features the Black Furies tribe that is just women Garou whose goals are to protect all women and children. Their characterization ranges from AmazonBrigade to WifeBasherBasher to StrawFeminist stereotypes. The Black Furies however are not all female through magic or genetic means, but philosophical. Black Furies can still have sons who may as they grow up become Garou themselves, but they are cast out of the Tribe for being male (which is a step up from being ceremonially sacrificed). The only exception are male Metis (children of the forbidden union of two Garou) either to atone for the sin of breaking the Litany or because Metis are by and large even more discriminated against in Garou society.

** The ''Series/StarTrekTheNextGeneration'' episode "[[Recap/StarTrekTheNextGenerationS5E17TheOutcast The Outcast]]" introduces the J'Naii, who once had two genders but "evolved" into a species with one gender. Some members of their race secretly identify as male or female and face persecution for it. The episode is a thinly veiled GayAesop episode about homosexual acceptance. In spite of the plot, the episode isn't really attempting to comment on gender identity, which had yet to become a widely recognized part of the nascent LGBT+ movement in 1992. A such, [[CluelessAesop it's a bit muddled to modern viewers]].

** Notably, they ''used'' to be a two-gender race, but their men went extinct, and reproduce using technology similar to cloning (they give the females some of the genes from males to make recombination easier -- they're genetic hermaphrodites, albeit not physical ones). They could technically become a regular two-gender race again if they would only mate with human males, but they like things just the way they are, thankyouverymuch. IE; guys weird them out.
** Certain parts of the manga actually do take a look at [[SurprisinglyRealisticOutcome the consequences of this setup]]: [[spoiler:The Arume initially invaded for the men but got cold feet, and apparently do so multiple times. Unless they buckle down and broaden their horizons, they're heading for societal collapse, either due to unrest on the occupied Earth, or due to Earth women not doing anything for their slowly degrading Y-chromosome supply (they'd find incorporating new ones icky)]].
%%* The Mazone in ''Anime/CaptainHarlock''.
* Zigzagged in ''Manga/CellsAtWork''; some types of cells have both male and female members (such as Red Blood Cells), some seem to only have males (e.g. Neutrophils), while others only have females (e.g. Macrophages). Depending on whose body we look at, these are also subject to change to represent blood type.
* The Namekians of ''Franchise/DragonBall''. [[WordofGod As described by]] [[Creator/AkiraToriyama Akira Toriyama]], Namekians are designed after slugs, and in-show they reproduce asexually (by laying eggs with their mouth). That said, their secondary sexual characteristics are distinctly male (see the fellow in the moustache in the picture above, although that guy only appears in an ImagineSpot that Yajirobe had, even before they visited Namek).

* In the ''Manga/ElfenLied'' anime, all Diclonius shown are female. They reproduce by infecting humans with their virus, via their vectors, invisible arms they control with their mind. They age slower physically than humans too. The only exception is the main character, who can reproduce in the same way as a human and appears to have aged at a normal rate. [[spoiler:However, there is one male Diclonius in the manga, Lucy's half brother.]]
* The Solnoids from ''Anime/GallForce'' were all female, and reproduced by cloning. Their enemies, the Palenoids / [[SpellMyNameWithAnS Paranoids]], were androgynous but ostensibly male (as far as the viewer can tell; they look more like living suits of armor, but all the voices are male). [[spoiler:The [[HalfHumanHybrid Half-Human Hybrid]] created from combining Solnoid and Paranoid DNA was a human boy, who was used to set up the [[AdamAndEvePlot ending]] of the original OVA.]]
* PlayedForHorror in ''Literature/GoblinSlayer''. Goblins are an entirely male species, but there's also [[ExplosiveBreeder a serious number of them]]. The reason is because [[RapePillageAndBurn whenever they attack a settlement]], they will always try to kidnap females and imprison them in their nests to use them [[BabyFactory to breed]]. Every single Goblin out there is a ChildByRape ''by default.'' [[RapeIsASpecialKindOfEvil And that's only when they feel practical about it. Other times, they do it for the sake of]] ColdBloodedTorture.
* {{Amazon|ianBeauty}}s in ''Literature/IsItWrongToTryToPickUpGirlsInADungeon'' is a female-only race. They're cross-fertile with all mortals, but will only give birth to Amazons.
* PlayedForLaughs in ''Literature/KonoSuba'' with the [[OurOrcsAreDifferent Orcs]]. Konosuba orcs are a race of [[BrawnHilda muscular]] [[PigMan (porcine)]] [[BrawnHilda women]] who rely on men from other species to reproduce. The males of the species were wiped out and on the rare occasion one is born they're usually [[OutWithABang "overworked" to death]] before reaching sexual maturity. In their first appearance a mob of them chase Kazuma down and attempt to mate with him [[BlackComedyRape against his will]].

* Angels[[spoiler:, Seeds of Life (Adam/Lilith), and probably the Evas themselves by extension]] in ''Anime/NeonGenesisEvangelion'' are strongly implied to be hermaphrodites: the genome analyses shows that they have 24 chromosome pairs, which includes both Y and X sex chromosomes (meaning they have the karyotype XXYY). The very existence of paired Y chromosomes generates a bit of FridgeLogic.

* In the ''[[Anime/SaberMarionetteJ Saber Marionette]]'' series, the human inhabitants of Terra II were all [[AWizardDidIt male, cloned descendants of the six male survivors]] of the colonization mission. The Marionettes were a 'race' of {{Robot Girl}}s that served as ReplacementGoldfish because they were not apparently able to create females [[ArtisticLicenseBiology (having X-chromosomes apparently didn't help)]], though their owners tended to have an ironically non-sexual attitude towards them.
* The titular Manga/{{Sekirei}} are overwhelmingly female (only 2 male ones have been seen so far, 3 if you count Homura).

[[folder:Card Games]]
* ''TabletopGame/MagicTheGathering'': Angels are always female. (There are two exceptions: one from an AlternateUniverse, and another that [[EarlyInstallmentWeirdness predates the style guide).]] Likewise, [[FemaleAngelMaleDemon demons are male]] when they have an identifiable sex. This is possible because they are not actually biological beings, they're [[MadeOfMagic manifestations of mana]] (white for angels and black for demons).
** The card art only shows females (MostWritersAreMale). The art directors once required an artist to redraw a card after he turned in a painting of a male angel. According to the books and text materials, there are plenty of male angels (Serra, at least, made sure of it for her realm).
** In the plane of Amonkhet, conversely, all angels are male. Demons are more bestial there; the one named is clearly male, but there are also Ammits, which are based off a female entity in Myth/EgyptianMythology.
* Maerynians in ''TabletopGame/SentinelsOfTheMultiverse'' started out in Sentinel Comics, the fictional comic book publisher the game purports to be an adaptation of, as an alien race that just happened to all look like dudes. Later writers established that Maerynians engage in asexual reproduction and are all capable of it, and their gender identities are pretty different from human, with "he" therefore not being a ''strictly'' accurate pronoun for Tempest but it works.
[[/folder]]

* The fairy-like Preservers in Wendy and Richard Pini's comic book series ''ComicBook/ElfQuest'' [[NoBiologicalSex are neither male nor female]]. Surprisingly, all the characters who encounter any given Preserver seem to know to automatically use the gender-neutral "it". The one known exception is from futuristic series ''The Rebels'' which has an apparently female elf-sized Preserver named Rosie, who has some percentage of human DNA because the Preserver DNA was not complete enough to clone a real Preserver.
* The Guardians of the Universe in ''ComicBook/GreenLantern'' comics were all male, because the females of their race thought the whole "guardians of the universe" project was misguided, and took themselves off to found an all-female society somewhere else. (They were {{Sufficiently Advanced Alien}}s, and practically immortal, so the continuation of their race was not a consideration.) When they died and were resurrected by Kyle Rayner, he intentionally made half of them female, to give them back that perspective (it didn't really work).
* In a story written by Creator/AlanMoore, "Vega: A Man's World" (''ComicBook/OmegaMen'' #27), a female alien anthropologist discovers another alien race composed entirely of males, with a tribal culture. When she describes the fact that it's possible to procreate with a female like her, the young man who acts as her translator is eager to try it (and she's fairly receptive, too). Unfortunately, the way the beings of this species procreate is by [[WhatDoYouMeanItsNotSymbolic stabbing a giant snail-like creature in a special purple membrane]], which causes babies of the tribe's species to bud off the snail (and also increases the numbers of the snails). The young man then brags to one of his elders that he's finally become strong enough to perform the ritual, the proof being outside his hut: a spear covered in red gore, as opposed to the purplish ichor of the snails.

* In Alessandro Barbuci's ''ComicBook/SkyDoll'', the Aquarians are an all-female race that reproduce through a cloning process utilizing genetic material from an object known as the "Holy Fish." [[spoiler:While it is not explained further, it is implied that Gaia, the figurehead of the race, has had relations with Agape, and possibly Noa, as well.]]
* In Archie's ''[[ComicBook/SonictheHedgehogArchieComics Sonic the Hedgehog]]'', the Bem species from Argentium are an all-female alien race, presumably due to cloning.

** ''ComicBook/WonderWoman1942'': The Neptunians are an all male extraterrestrial race.

** ''ComicBook/WonderWoman2011'': In the ComicBook/{{New 52}}, Amazons apparently are [[FemmeFatale Femmes Fatales]] who have sex with passing sailors and then murder them. Any male children born are traded as slaves to Hephaestus in exchange for weapons.

* Leprechauns in ''ComicBook/WormwoodGentlemanCorpse'' are all male. [[spoiler:Even the queen.]] We aren't given details on how they reproduce.
* Nearly every mammal species on Earth becomes this in ''ComicBook/YTheLastMan'', after a strange event somehow [[{{Gendercide}} kills off every male mammal on Earth]] except two, a human and a monkey. (The "on Earth" part becomes important later, as [[spoiler:the International Space Station wasn't affected]])

* ''Fanfic/TheBridge'':

* The Nendo-kata are an all female race first created for Frederick Dean Herriot’s ''Manga/UruseiYatsura'' fanfic series ''The Senior Year.'' They first appeared in ''Together the Outland,'' then afterward. They've also showed up in ''Urusei Yatsura - The Ishinomaki Years,'' his Ranma 1/2 stories ''Three Sisters'' and ''Like A Phoenix From The Ashes,'' plus his ''Anime/BubblegumCrisis'' series ''Illusions.''

** [[spoiler: The Rinne arc reveals the [[OurSpiritsAreDifferent Spirits]] were an all female race before their demise, hence why only girls can bond to a Sephira Crystal. Even [[TheHero Shido]], who's the only boy with any Reiryoku, is stronger when he's transformed into Shiori]].
** [[spoiler: All of the Demons are shown to be male, in contrast to all of the above-mentioned Spirits being female]].

* ''Fanfic/FalloutEquestria'': All the artificial alicorns are female; when they begin regaining their minds, one mentions that she remembers [[GenderBender she used to be a stallion]]. Because of the fact that the "templates" used to create the alicorns are all female, any newly created alicorn is female. Part of the reason they sided with Red Eye was because he promised them male alicorns so that they could breed. [[spoiler:Red Eye's plan fails, but the alicorns bring his data to Velvet Remedy. She is eventually able to devise a way to change some of the alicorns back into stallions, and in the afterword there are several newborn alicorn foals]].

* Subverted in Raven Child's ''Fanfic/TheSmurfetteVillage'' series, as it shows how both male and female Smurfs were created in the beginning and why they were separated into two single-gender villages.

* [[DownplayedTrope Downplayed]] in the ''[[WesternAnimation/DisneyFairies Tinker Bell]]'' movies, where female fairies are more common than males.

* 90s film ''Film/LeapinLeprechauns'' present all leprechauns as male and all fairies as female. When a character asks if they marry each other, both sides react offended by the idea.
* The Venusians met in ''Film/AbbottAndCostelloGoToMars'' are all female, having banished the males and claiming to have perfected immortality. One or two small girls are seen, so it's possible some form of pro-generation goes on.
* Boogymen in ''Film/DontLookUnderTheBed''. This is reveled at the end when the Boogeyman [[spoiler:turns into Frances' imaginary friend, Zoe, who insists on using boogeyperson.]]

* A Creator/GarryShandling vehicle named ''Film/WhatPlanetAreYouFrom'', starring the comedian as a member of an all-male alien race [[MarsNeedsWomen sent to Earth to procure a mate]].

* While not exactly a single race or species, dinosaurs in ''Franchise/JurassicPark'' are all female to prevent uncontrolled reproduction. [[spoiler:Or that's what they thought.]]

* Vampires in ''Film/PerfectCreature'' are exclusively male, the result of a mysterious virus that causes normal women to give birth to vampires. No female was ever born, coupled with the fact they can't turn other people into vampires and are unable to breed with humans, their propagation hangs solely on more Brothers being born from this virus. [[spoiler: The plot is kicked off when its revealed they haven't produced any new members in 70 years and they turn to genetic manipulation to fix this, unleashing one crazed vampire scientist in the process]].
* The Hutts of ''Franchise/StarWars'' are [[{{Hermaphrodite}} hermaphroditic]], but as a cultural thing, they alternate gender terminology between the periods when they are capable of reproduction and when they are not (as a result, we could consider them a ''genderfluid'' race). At least, that was the case in the ''Franchise/StarWarsLegends'' continuity. The new ExpandedUniverse has made them dual sexed again, without the gender switching.

* In ''Film/KissMeQuick'', the inhabitants of the Buttless Galaxy are all of a single sex (seemingly male, but that might just be outward appearance) that reproduces by splitting like amoeba. Sterilox is astounded when he is told there exist races with two sexes. He is sent to earth to [[MarsNeedsWomen acquire a superior specimen of womanhood who can act as the progenitor for a servant race]]. Dr. Breedlove shows him a wide variety of examples of feminine pulchritude in varying stages of undress, but never having seen a woman before, Sterilox has no idea what he is looking at, or what he is supposed to be looking for.
* Krasnoludki in ''Film/{{Kingsajz}}'' are all male, which is part of why the MagicPotion that allows {{Sizeshifting}} (and meeting normal-sized women) is in such a high demand.

* In Christine Feehan's ''Carpathians'' series, the titular [[OurVampiresAreDifferent "pre-vampire"]] species have very few females, mostly due to them not being born very often, or not managing to survive the transition between drinking mother's milk and drinking blood. This leads to male Carpathians either fighting it out for the few females, or [[MarsNeedsWomen finding telepathic human females to mate with.]]

** The {{golem}}s, being created beings, are genderless. Until ''Literature/GoingPostal'', when one of them gets named "Gladys" so the postmistress doesn't object to her cleaning the ladies' privies. Since golems believe what they've been told to, Gladys is subsequently female, and people think of her as such. (And in ''Literature/MakingMoney'', Moist notes that, somehow, this seems to make the "default" golems male.)

* ''Literature/ImmortalGuardians'': Across 13 books, the Immortal Guardians have yet to encounter a female vampire. Seth, the Immortals' leader, explains that this is because it takes several feedings across several days to convert a human to a vampire and the sociopathic, sadistic male vampires tend to lose control and rape and murder any females they capture long before the conversion process can be completed. Female Immortals are also rare as most Immortals were humans, turned against their will only for their enhanced humans DNA allowed them to heal after being left for dead by the vampires who turned them. But again, the females tend not to survive long enough to begin the healing process. Immortals can turn Gifted Ones, but usually only do so for the person they intend to mate, preferring to allow humans to remain human.

* The koloss from the ''Literature/{{Mistborn}}'' trilogy are all male, though this is because they are an unnatural race and do not reproduce by normal means. [[spoiler:Instead, they're created by binding five people together with a special skin and four hemalurgic spikes. This is why they're as strong as five people and are confused by conflicting memories.]] By ''Literature/WaxAndWayne'', this has changed; Harmony made it so that they have natural genders and can reproduce. The child of a koloss is a "koloss-blooded," stronger and tougher than ordinary humans. Once they come of age, they can then choose to make the transformation into a full koloss or leave the clan. Ordinary humans can also choose to join the clan and make the transformation; no distinction is made from a koloss who was originally an ordinary human and one who was koloss-blooded.

* Appears several times in the works of Creator/RoaldDahl:
** In ''Literature/TheBFG'', all [[OurGiantsAreBigger Giants]] are male; the BFG explains that giants simply come into being.
** ''Literature/TheWitches'': All [[WickedWitch Witches]] are female (though they don't interbreed with humans and are all evil), but as they are demons and not humans, it doesn't particularly matter. The book also mentions barghests and ghouls to be all-male.

* Chief Engineer Burgoyne 172 in the ''Literature/StarTrekNewFrontier'' novels is a member of a hermaphroditic race called the Hermat. S/he dismisses comparisions to the J'Naii by explaining "They are neither. We are ''both''."

* ''Literature/{{Xanth}}'': [[DistaffCounterpart All-male satyrs mate with all-female dryads, and all-male fauns mate with all-female nymphs]]. Harpies were this for a while, forcing them to alternate vulture and human mates with each generation or die out (with such crosses always female), until a male harpy returned from suspended animation a long way into the series.

* ''Series/BabylonFive'':
** On screen, all pak'ma'ra have just one gender, which is neither male nor female, reproducing asexually through parthenogenesis every five years or so. However, they do engage in carnal acts that would otherwise be viewed as sexual, including with [[BoldlyComing other species]] (assisted by technology when necessary), though purely for recreation. Given this they lack a concept of marriage, with most living alone, though some do have what are called "thought mates" which are more like a very close friend. Nevertheless expanded material subverts this as other sources like the Role Playing Game guide says that actually their humps are their females (pak'ma'ra without humps are the equivalent of a single person).
** In ''Series/{{Crusade}}'' the Drazi are mentioned to be hermaphroditic and all look and act like males in-universe. (Nevertheless this might contradict the fact that in the mother series ''Series/BabylonFive'' Londo mocks the Drazi ambassador implying that his wife had an affair. Of course whether this still means that they are hermaphrodites and still marry and one of them assumes the role of wife or Londo didn't know that they are hermaphrodites is up to you).

** The history of the Time Lords is, as with so many things, muddled. Technically, the second Gallifreyan we ever saw was female, although Susan wasn't even around when [[ContinuityDrift the concept of Time Lord even existed in the show]] — the Doctor was AmbiguouslyHuman during her tenure, and she was only said to be Gallifreyan retroactively. For about a decade, all the Time Lords seen after the introduction of the concept were male; even the name implies this. Creator/TomBaker assumed the Time Lords were all male and purposely played his Doctor a little awkward around women to give the impression, with the Sisterhood of Karn even coming across as the Time Lords' DistaffCounterpart. However, seventies ''Doctor Who'' was rather unclear as to whether "Time Lord" was the name of the race, or a title for members of the Chapters, which would make Tom's portrayal more of an unworldly Oxbridge don from the days when women weren't allowed on campus except as housekeeping staff. Regardless, the introduction of Romana in 1978 removed this assumption, and several Time Ladies have appeared since. In fact, with the Master becoming the Mistress (and the General in [[Recap/DoctorWhoS35E12HellBent "Hell Bent"]], and now Creator/JodieWhittaker) it has been established that Time Lords(/Ladies) can change sex when regenerating. So they're not so much a one-gender race as an all-genderfluid one.

** The Drahvins, from the William Hartnell story [[Recap/DoctorWhoS3E1Galaxy4 "Galaxy 4"]], are a seemingly all-female race. They use the few males only for breeding. Their commanders are naturally born and their footsoldiers are clones.

** The Sontarans are a militant male-presenting race who reproduce through cloning. They have noticeable difficulty with the very idea of gender (e.g. two genders is "a bit further than they can count"). According to some of the ExpandedUniverse material their species originally reproduced normally and was far less war fixated until the day a horrendously narcissistic military man, one General Sontar, started cloning himself and slaughtered the rest of the population. The canonicity of this is disputed, however.

** The Sisterhood of Karn in [[Recap/DoctorWhoS13E5TheBrainOfMorbius "The Brain of Morbius"]] are all female and do not reproduce, being instead immortal. The ExpandedUniverse and revived series retconned them into a Time Lord faction instead of a distinct race.

** [=TARDISes=] apparently. In [[Recap/DoctorWhoS32E4TheDoctorsWife "The Doctor's Wife"]], [[spoiler:the TARDIS herself said that House's planet was filled with the corpses of her sisters. Well of course — ships are always female.]]

* ''Series/TheOrville'': Moclans have only males. [[spoiler: Turns out they do have females, but they're rare and Moclan society mandates that they be surgically reassigned as males, as Moclans consider the female gender a horrific birth defect that needs to be fixed. Later we learn of a hidden colony world in "Sanctuary" that is settled entirely by Moclan females, to spare them being forcibly "corrected" into males.]]
* In ''Series/TheOuterLimits1995'' episode "[[Recap/TheOuterLimits1995S4E17Lithia Lithia]]", the world is now an all-female post-apocalyptic society in which almost all males were wiped off the planet due to war and a virus. They decide to not reintroduce the remaining men into the population because every time they took one out of stasis, it caused conflict in the society because the men pushed limits that the elders were not comfortable with, like building generators or stealing from other towns. Sucks to be male.
* ''Franchise/StarTrek''
** The Jem'Hadar on ''Series/StarTrekDeepSpaceNine'', genetically engineered by the Founders to serve as soldiers. Weirdly, though they are also cloned, the Vorta are ''not'' single-gender. Probably because the Vorta were adapted from a pre-existing species, while the Jem'Hadar seem to have been created out of whole cloth (it might also have something to do with the Vorta being intended as diplomats). Earlier in the series we were introduced to a never again seen Gamma Quadrant species that was awfully similar to the Jem'Hadar, except with more limited versions of their abilities.
** [[http://memory-alpha.org/wiki/Captive_Pursuit_%28episode%29 Word of God]] states the [[Recap/StarTrekDeepSpaceNineS01E06CaptivePursuit Tosk]] were created by the Dominion as a gift to the race that hunts them.
** ''Series/StarTrekTheNextGeneration'' introduces the J'Naii, who once had two genders but "evolved" into a species with one gender. Some members of their race secretly identify as male or female and face persecution for it. The epsode is a thinly veiled GayAesop episode about homosexual acceptance. In spite of the plot, the episode isn't really attempting to comment on gender identity, which had yet to become a widely recognized part of the nascent LGBT+ movement in 1992. A such, it's a bit muddled to modern viewers.
** [[Recap/StarTrekS2E15TheTroubleWithTribbles Tribbles]]. One sex, seemingly born pregnant, according to Dr. [=McCoy=]. ("Seems to be a helluva time saver!")
** The Taresians of ''Series/StarTrekVoyager'' are a species consisting entirely of females that mate with males of other humanoid species to perpetuate themselves by implanting viruses in them that slowly turn them into male Taresians. As it turns out, the mating process (one male is given up to three females as his wives) is deadly toward males as [[OutWithABang they die after mating with their wives]]. Harry Kim was implanted with a virus that made him believe that he was secretly a Taresian, but eventually he and the Voyager crew find out the truth about the Taresians and rescue Kim before he became their next victim.
* ''Series/TidelandsNetflix'': Sirens are all female and they reproduce by mating with human men. Hybrids which result appear human, both male and female. It's left unclear where original sirens come from, though Bill says they've been in the waters forever.
* ''Series/TheTwilightZone1959'': In "[[Recap/TheTwilightZoneS2E55MrDingleTheStrong Mr. Dingle, the Strong]]", one Martian notes that one of the three planets on their itinerary after Earth seems particularly interesting, since it contains only females.
* ''Series/YTheLastMan2021'': With all the men gone, this is what the human race becomes (biologically-they also make a point of mentioning there are plenty of men, just all are trans men) - short lived as it will last.

* The subject of whether angels are all male in ''Literature/TheBible'' has been subject to debate. The Bible itself never says that angels are all male, but this is assumed to be the case due all named angels having male forms of their names (For example, Michael and Gabriel) as well as male pronouns being exclusively used for angels. Some interpret "the sons of God" having [[{{Nephilim}} children by women]] as meaning angels who ''did'' have sex (and so presumably bodies, unless this involves [[DemonicPossession possessing humans]]) while some apocrypha (like the Book of Enoch) supports the idea. Another line of thought is that angels are [[NoBiologicalSex genderless and sexless]], because they exist on a different plane than humans and thus cannot be perceived as being the same as us, with this supposedly being supported by the statement that angels in heaven did not marry. That being said, angels being genderless is never indicated in the Bible despite being a popular interpretation. Regardless, this hasn't stopped the depiction of female angels in artwork, and the named archangels themselves have been subject to some gender-bending in media.
* Chinese [[OurDragonsAreDifferent dragons]] are often depicted as being always male, in contrast to the always female [[https://en.wikipedia.org/wiki/Fenghuang fenghuang]] (a mythical bird similar to ThePhoenix).
* OlderThanFeudalism: Myth/GreekMythology has many humanoid beings that appear to be of a single sex, such as female harpies, male satyrs, male centaurs, and female nymphs (which are minor deities that can interbreed with human men). This has inspired many of the other examples on this page. In late Classical works there were female centaurs and satyrs, but these are unusual cases; kentaurides (the female centaurs) were barely spoken of in ancient Greek literature and only one example, Hylonome, is mentioned by name, while the satyresses (the female satyrs) are [[CanonImmigrant Canon Immigrants]] from late 15th/early 16th century poems and art, and didn't exist at all in the ancient works.
** Originally satyrs were depicted as human men with beards, bald foreheads, pug noses, pointed ears, horses tails, and constant erections. Technically, only the tails and ears set them apart from standard image of a 'wild man'.

** Greek mythology also had the [[http://en.wikipedia.org/wiki/Gargareans Gargareans,]] an all-male tribe and SpearCounterpart to the Amazons. The two tribes depended on one another for reproduction.

* Angels are always male according to ''Literature/TheQuran.''
* Some mythologies depict fairies as always female. The human-sized fairies in French fairy tales are always described as female (although similar male beings called genii, wizards, or enchanters appear in some stories, who might be their [[SpearCounterpart male counterparts]]). Several stories feature fairies marrying human princes.
* In Western folklore, werewolves are [[DownplayedTrope almost]] always male, as human men tend to get hairy later on in their lives during puberty.
* The Valkryies in Norse mythology are all female.

* The Medusas of ''TabletopGame/{{GURPS}} TabletopGame/{{Banestorm}}'' are all female. They mate (carefully) with humans, elves, and orcs' males to produce offspring. The kids are usually medusas, but some are boys with a recessive medusa trait. WordOfGod says that the world of the Banestorm also has ''Euryales,'' a small all-female reptilian race, whose eggs are fertilized by eating their dead; and ''Sthenos,'' a much bigger all-female reptilian race, produced by a virus that infects human (or orc or elf) women, and spontaneously transforms them if they are violently injured.
* In the paper-and-pencil RPG ''TabletopGame/CastleFalkenstein'', Dwarves ''are'', in fact, exclusively male. They mate with the females of other Faerie-kind (some varieties of which are all-female); male offspring are Dwarves, while female offspring are the same kind of Fae as their mother.

** In 2nd Edition ''AD&D'', the standard version of the minotaur is an all-male race. New minotaurs come into being when a human male is cursed to become one by the gods, or when a minotaur abducts and impregnates a human woman. This only applied to the "default" version, and minotaurs from specific game-settings such as ''Literature/{{Dragonlance}}'' did come in two genders. (4th Edition averts the trope altogether.)

* ''TabletopGame/InNomine'': While celestials usually tend to see gender roughly the same way humans see specific outfits -- interesting and potentially appealing, but not usually something central to one's identity -- the Archangel Zadkiel is firmly female, and roughly eighty percent of her angels of Protection choose to manifest as female -- she will grant male vessels, but it takes some effort to convice her. This is interesting since she is a Muslim, a faith which specifically says that angels do not appear as female. This is a bone of contention between her and Khalid, who hews more strictly to the dogma of Islam then Zadkiel does; Zadkiel believes that bit of the Qur'an to have been a misintranslation from Angelic to Arabic.
* ''TabletopGame/{{Pathfinder}}'':
** Xills (a CaptainErsatz of [[ChestBurster A.E. van Vogt's Ixtl]]) and thriae ([[WomensMysteries inscrutable seers]] based off of [[BeePeople bees]]) are all female. The [[FishPeople Deep One-inspired skum]] are all male.
** Pathfinder's first edition had a number of all-female monsters, many of whom reproduced by abducting, raping and devouring humanoid males. Second edition vastly cut down on the number of these, with many of these species, including lamias, harpies and mariliths now being explicitly stated as having both male and female members. Hags are some of the only remaining exceptions-- they're still exclusively female.
** Hags in 1st Edition give birth to all-female {{changeling|Tale}}s, who must be persuaded, tricked or coerced into undergoing a magical ritual to become hags in turn. Well, to be accurate, they have male offspring as well, but A: very rarely, and B: they kill them on birth. 2nd Edition has altered this to have male changelings as well, though they are much less likely to feel the psychic call that urges them to take part in the hag transformation ritual.
** ''TabletopGame/{{Starfinder}}'' gives us ramiyels and vilderaros, both of which seem to be hermaphroditic species that exclusively identify as female. (And, in the case of [[SnakePeople ramiyels]], ''present'' as female; [[StarfishAliens vilderaros]] don't really ''do'' any recognizable sort of gender presentation.)

* Lampshaded in ''TabletopGame/{{GURPS}} Dungeon Fantasy'': "there are female fauns, and bringing up the myth that fauns and nymphs are males and females of a single species is an excellent way to start a fight."
* ''TabletopGame/TranshumanSpace'' features a few StrawFeminist geneticists trying to engineer an all-female human subrace.

* Games Workshop:
** ''TabletopGame/Warhammer40000'' The Orks in (and possibly the Orcs in ''TabletopGame/{{Warhammer}}'') seem to be all ridiculously masculine, early [[RetCon non-canonical]] references to female Orks notwithstanding; however, since [=Wh40k=] Orks are actually a hybridization of mammal and ''fungus'' that reproduce via spores, attempting to assign a gender to them is an exercise in futility.

** In case you were wondering, the old fluff was such: On the battlefield, you ''did'' have Female Orcs, but they were all in "War Mode", which made them all identical to the males. Once their numbers dropped enough however the Orcs would retreat and go home(or settle in if their conquest was successful), and their sexual characteristics would develop, allowing them to reproduce and replenish their numbers for the next war.
** According to one supplement, the Gene-Seed—the stuff that makes SpaceMarines grow to nine-foot tall poison-drinking, car-lifting supermen—is only compatible with male genetics. This is probably due to several of the upgrades being essentially weaponized TestosteronePoisoning.

** Chaos Daemons, aside those of Slaanesh, are generally mono-gendered because they're fragment representations of their respective Chaos Gods. This is because rather than being born biologically, they're created via other methods (Khornate and Tzeentchan Daemons are usually created by actions of their respective gods, while Plaguebearers are spawned from the departed souls of people who die from Nurgle's plagues). Slaanesh is a special case because he/she/it and all of his/her/it's daemons tend to switch pronouns depending on who you ask (Eldar exclusively refer to Slaaneshi daemons with female pronouns) and technically Slaanesh is a hermaphrodite.

** The Lizardmen in ''TabletopGame/{{Warhammer}}'' are all males; they are born from spawning pools throughout Lustria, and were initially created by the Old Ones. Their war with the Skaven began when the Skaven poisoned one city's spawning pools.
* ''Toys/{{Xevoz}}'' gets hit hard with this one -- six races, with two more added later on, and every single member is male, or at least lacking any distinct female traits (one race is EnergyBeings after all). Unless you consider that ony the drones in an insect colony are male, and the two character types under the BigCreepyCrawlies race are heavily implied to be soldiers rather than drones.
* ''TabletopGame/TheWitcherRolePlayingGame'': The Dryads employ an army entirely composed of naked ActionGirl archers.

* In ''Toys/{{Bionicle}}'', there were different types of the Matoran (and Toa and Turaga) species, grouped by different ElementalPowers. Most elements are male only, including five of the six common elements. The only of the six most common elements to be all-female is water, along with some uncommon elements. The only co-ed element is light. [[WordOfGod As explained by writer Greg Farshtey]], there originally weren't supposed to be any female characters in the series. A Toys/{{Lego}} exec recommended marketing the toys to girls as well, so one of the six original tribes was made all-female, and then this setup just stuck, but only for the Matoran species. Justified in that Matoran gender differences are psychological and they weren't originally created to be sentient. They only gained sentience thanks to [[spoiler: Velika's]] experiments.

* In ''A Hint of a Tint'' all of the species who inhabit the Sanctuary are all-female. Breeding is accomplished with the use of male "Tailless" (i.e., humans), who inevitably die after several days due to their inability to drink the local water.

* The Kaka clan of ''VideoGame/BlazBlue'' are at least close to being a [[spoiler:genetically engineered]] one-gender race that reproduce via parthenogenesis. Kaka males are mentioned as being incredibly rare, and none are seen in game.

* Only male Grendels and either male (in ''2'') or female (in ''3'') Ettins occur without player intervention (or breeding, once you have both genders) in the ''VideoGame/{{Creatures}}'' games.
* ''VideoGame/{{Darkstalkers}}'': The [[CatGirl Catgirls]] for Fanservice purposes.
* Archers from ''Franchise/{{Disgaea}}'' were always female and created by their WorldTree until the [[VideoGame/Disgaea3AbsenceOfJustice third game]], but the males were referred to as "rangers" instead. Then there are the succubi and catgirls. Since each class is gender-specific, there are duplicate [[SpearCounterpart male]] and [[DistaffCounterpart female]] counterparts of most classes. Since the "monster" classes are all gender-specific, as well, but monsters are, through Mediators, capable of marrying and producing offspring, it's safe to assume that GenderEqualsBreed.

** This was widely believed of the Qunari in-universe until envoys came to Seheron. Only male qunari fight as soldiers, and soldiers were the only qunari seen until a peace was struck. No female qunari had been seen prior to ''Inquisition.''
** The descendants of Andraste, the game's chief human deity, a Jesus/Mary/Mohammad/Joan of Arc analog, are speculated in universe to be exclusively women. She had two daughters with her mortal husband. Andraste's older daughter had one child, but that granddaughter died childless. Andraste's younger daughter had a [[MassiveNumberedSiblings large number of children]]. However, they were all girls, and ''they'' only had girls, and so on. But since these women married into other families, and because [[ApocalypseHow the Second Blight]] destroyed so many records, historians lost track of them through the ages. This means no one knows who the present-day Descendants of Andraste are, only that they're all women.
* ''VideoGame/DungeonSiegeII'' has the Dryads. Quoted from page 40 of the manual, "These creatures resembled Human females in many ways. (If there are male Dryads, they keep themselves well-hidden. None has ever been seen." Also, "No one knows how they reproduce (any enquiries on the subject are met with hostile silence)".
** Half Giants are all male, though they can procreate with other races. A quest explains that [[spoiler: they originated when a group of Agallan giants betrayed their kin and for this they and their offspring were cursed to be small. There were no women among the traitors, so all Half-Giants are male.]]

* Also in the ''Franchise/FinalFantasy'' franchise, the entries part of the "[[VideoGame/FinalFantasyTacticsAdvance Ivalice]] [[VideoGame/FinalFantasyXII Alliance]]" (aside from the all-human original ''VideoGame/FinalFantasyTactics'') feature the Viera. Except for humans, most other races are effectively all-male, as well, but it appears simply because they have no alternate gender appearance, and ''VideoGame/FinalFantasyTacticsA2'' has a Luck Stick vendor and exchanger who are described in-game as male and female, respectively, in spite of appearing completely identical. The Seeq have an official female sprite, though it's just a Seeq Viking with a pink outfit and lipstick, and not playable.
** Officially there are male Viera, though none have been featured for a very long time until ''FFXIV''. According to canon sources, they live separate from the female half of the species and the two populations only meet when it's babymaking time. A young, spoiled Viera appears in a series of missions in [=TA2=], and wants the player to help her capture a Wyrm so that she can take it home and impress her father. So far, Gria have only appeared in one game of the Ivalice series, and their role was tertiary at best, so no word yet on how their society functions.
** Tactics A2 plays with your expectations a little, with the Duelhorn Boss, Night Dancer. From first appearances you might think she's the only female Bangaa character and therefore is safe for your Viera unit to hit under the "No Harming Opposite Gender" law. But no, she's [[UnsettlingGenderReveal got a pickle surprise.]]
** ''VideoGame/FinalFantasyXII'' introduces the Garif. [[SpearCounterpart like the Viera]], all of the ones that you meet are a single gender, though in this case they're all males. Also like the Viera, canon sources outside the game state that the two genders live separately.
* Mithra and Galka in ''VideoGame/FinalFantasyXI'':
** Galka are male-only, and "reproduce" by reincarnation. It is suggested that the number of Galka in the world is either fixed or slowly decreasing due to premature death.
** Players can only choose to play female Mithra, with the excuse that the number of male Mithra is so critically low that they have been forced into protective status while the females are the ones that venture outside their homeland to adventure and hunt. It is not exactly an enviable position as most males are forced into passionless sex for reproductive purposes, but a few certain males with intelligence and loose morals (like Lehko Habhoka) use their rarity to gain power and status.
** Later, an all-female [[AlwaysChaoticEvil enemy race]] called the [[SnakePeople Lamia]] was added to the game, though their status as one may be [[JustifiedTrope justified]] by the insinuation that they're actually an artificial race used as biological weapons...and because the [[OurMonstersAreDifferent mythical creatures]] they're based on are always depicted as female.
* ''VideoGame/FinalFantasyXIV'' had races based on ''XI'''s, so like the Galka and Mithra, the Roegadyn were only male and Miqo'te only female. The opposite sexes of the races ''did'' exist; a prominent NPC, Merlwyb, was a female Roegadyn. However, as of ''A Realm Reborn'', both males and females of all races are playable.
** The [[SnakePeople Ananta]] are an all-female beast tribe introduced in ''Stormblood'' who are able to reproduce without the need of males, which they consider to be a blessing from their goddess Lakshmi.
** The ''Shadowbringers'' expansion includes two playable monogender races: the all-female Viera from ''FFXII'' (which also downplays this trope, since lore already established that there are males who never leave the homeland), and the all-male Hrothgar, a race of burly men who have furry characteristics that make them like like anthropmorphic big cats. Similar to the male Mithra lore, it's stated that female Hrothgar are incredibly low in numbers and are kept in their homeland to help populate their race. However, the following expansion, ''Endwalker'', adds playable male Vieras to the game, making it their first ever depiction in the series (playable female Hrothgars are still pending).

* The playable cast of ''VideoGame/KanColle'' and ''VideoGame/ToukenRanbu''. The former consists of female personifications of battleships and the latter male personifications of Japanese swords.
** In ''Touken Ranbu's'' case, there's a reason for this as the characters are "tool kami", (called "Tsukumogami" in Japanese), tools, or in this case katana, that have been given a spirit after a period of at least 100 years following their creation. ''Touken Ranbu'' confirmed via Houchou's voice lines that there aren't any female Touken Danshi, much to his disappointment. Some swords that were wielded by female owners or are considered "feminine weapons" (such as the Naginata) will have feminine looks, but that's as far as it's gone and they are otherwise a race of pretty boys.

** The Gerudo are an entirely female human race of warrior-thieves, who are expected to leave the desert, usually temporarily, if they're inclined to find men to make more Gerudos. Oddly enough, though ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' states that one Gerudo male is born every hundred years, there is no special fanfare beyond being appointed king by tradition (the only one known is [[BigBad Ganondorf]] which doesnt work out too well...). The point may be moot, as the ''Creating a Champion'' artbook states that by the time of ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]'' a male has not been born to the Gerudo for countless millennia (however, ''[[VideoGame/TheLegendOfZeldaTearsOfTheKingdom Tears of the Kingdom]]'' shows that it was because Ganondorf [[SealedEvilInACan was actually alive the whole time]]).

** The asari are a single sexed race that at least looks entirely female, who can reproduce either through parthenogenesis or via some complex partially psychic reproduction with each other[[note]]Though an odd bit of gender diversity occurs in this situation: The asari that gave birth is the mother while the other parent is considered to be the father, even though both appear to be women from an outsider's perspective.[[/note]]. They're also among the wisest and most ancient races in the galaxy, powerful users of biotic techniques, and the founders of the Citadel Council, which governs 80% of known space. But the player is likely to be more interested in their ability to 'merge' with anyone, regardless of race and gender. The asari even have a [[FantasticRacism Fantastic Self-Racism]] against asari who join with other asari. Partly because the race feels that nothing new is gained from merging with other asari, and partly because only "pureblooded" asari can be born with a genetic birth defect that causes them to be sterile, kill their partner when mating and quickly grow addicted to this sensation, becoming serial killer sex vampires. As such, everyone with this disorder is locked into convenes.
** There isn't as much focus on it, but most of the other non-human races are functionally one-gendered races as well, at least in the first two games. That is, females are either implied or stated to exist, but are never seen due to lack of an in-game model. A female krogan (just one) and a female turian are finally seen in ''Mass Effect 3''. There are also two female salarians (one if you saved the Council in ''Mass Effect''), but they look identical to the males. It's stated in the Codex that salarians have far fewer females than males and as a result of this most females stay on their homeworld and major colony worlds to stay safe and make sure the species can still reproduce. Female krogan and turians become much more common in ''Andromeda''.

* The Lochladies from ''VideoGame/SuperMarioOdyssey'' are all female. It's even indicated on their name.
* In the MMORPG ''[[VideoGame/TricksterOnline Trickster]]'', Cats, rabbits, foxes, and sheep are female, raccoons, dragons, lions, and bulls (well, duh) are male. Less so than most examples in that all the characters [[LittleBitBeastly are really humans with costumes consisting of a headband and a tail]].
* ''Every'' race except Poms in ''VideoGame/NeoSteam''. Even the ''Humans''. Humans are all male, with a female counterpart race in Taxn Humans. Lupine and Tarune are all male, with an all-female counterpart race in the Lyell. Elves are just plain all female, with no male counterpart. They're not actually stated to be all male or all female, but those are the only options available to {{PC}}s, and we don't see any {{NPC}}s contrary to this pattern, either.
* Nor do they exist in the online collectible trading card game "Hex: Shards of Fate". It is explained that when a dwarf dies, they crumble into a pile of pebbles which are then used to make more dwarves. Also, the Vennen (a race of spider people) are all male and reproduce by capturing other races, (especially their sworn enemies the Orcs) tying them up in giant spiderwebs, and using them as incubation slaves.

* ''VideoGame/{{Pico}}'': In ''Love Conquers All'' Cassandra explains that Penillians are a one gender race and are thus all considered homosexual by default. That being said, different Penillians take on either "male" or "female" human disguises depending on personal preference and they are implied to be hermaphroditic.

* Pixies in ''VisualNovel/SablesGrimoire'' are all tiny beautiful [[WingedHumanoid butterfly winged]] women living in isolated villages. Since they are generally only seen by humans when making use of {{Sizeshifter}} powers to breed with male humans to reproduce they have acquired a reputation for lasciviousness.
* You rescue eighty dragons in ''Franchise/SpyroTheDragon'', but every single one is male and female dragons are never mentioned. Averted in the third game, which features female baby dragons, which means that the female dragons were off laying their eggs in solitude -- [[FridgeBrilliance Gnasty missed them completely]].

* In ''VideoGame/{{Startopia}}'', all alien species are [[DittoAliens identical]], except the sexy Dahanese Sirens - beautiful humanoids with angel wings whose role on the station is to "love" other beings. They have two models, one purple-haired woman in a racing swimsuit, and one blonde, shirtless man. WordOfGod is that it's a BizarreSexualDimorphism: the males are the ones in swimsuits and the females are the shirtless ones.

* In ''VideoGame/WarcraftIII'''s campaign, the Night Elves begin as a one-gender race, until the male Druids, who have apparently been hibernating for a long, long time, awaken.
** Even in ''VideoGame/WorldOfWarcraft'', there are many more female Night Elves than male. This is probably a RuleOfSexy choice by Blizzard and the players, and the ({{Hand Wave}}d) reason for this is probably that many males are still trapped within the Emerald Dream. If players are ever allowed to visit the Emerald Dream, one can bet that there will be plenty of male Night Elves running around.

** Oracles, Murlocs, and Kobolds seem rather one-gendery.... though they maybe don't have any sexual dimorphism at all. Furbolgs are a good example of this. The one female furbolg seen looks exactly like every other furbolg out there.
** Several races have both genders according to the lore, but only one (male, with an exception being the succubus) is depicted in game. Ogres, Broken and Lost Ones, for example...although a half-finished female Broken model exists in the game source. Literally ''half''-finished. If the macro system's [=UnitSex=]() function is to believed, some of the 'all male races' such as Ogres do have female individuals in the game. Apparently the player characters just can't tell the difference.
** The Warcraft D20 monster manual states explicitly that Harpies reproduce by raping a captured humanoid race, preferring elves and humans.

* ''VideoGame/ShantaeAndTheSevenSirens'': As said by the pink-haired tourist in Arena Town, "And all Half-Genies are women."
* In the ''VideoGame/{{X}}-Universe'' series the [[ProudMerchantRace Teladi]] ''do'' have males, but they nearly all still live on the homeworld because the species discovered early in their space age that unfertilized eggs would always hatch females, and their [[LostColony homeworld was cut off]] from the PortalNetwork for 600 years. Even someone who deals with Teladi regularly will likely never meet a male, so this trope is the public perception.

* ''VideoGame/XCOM2'' introduced the Vipers, a race of all-female SnakePeople with [[NonMammalianMammaries venom glands for breasts]]. In the "Alien Hunters DLC" you encounter a Viper King, the only male instance of the species encountered, and Dr. Vahlen discovers that their species is like this as a result of genetic manipulation by the Ethereals.
* ''VideoGame/TheWitchesTeaParty'': Witches are shown to be all-female, but it's clearly implied that they can breed with humans.

* ''Webcomic/{{Bardsworth}}'': The faeries are all female and the demons all male. New faeries are born by combining magic and a [[http://www.bardsworth.com/archive.php?p=186 tree]]

* In ''Webcomic/DangerouslyChloe'', Succubi are a single-gendered species; there is no naturally occurring male equivalent (such as the Incubus). There ''is'' a loophole though, Succubus are capable of changing their gender to male, but Chloe explains this is taboo even for demons, as once a Succubus becomes male not only do they become incredibly more dangerous, but it becomes nearly impossible for them to change back (Teddy becomes a male Succubus/sex demon at one point, and it seems in addition to increased power and strength, his sexual appetite becomes insatiable, moreso than even the typical sex demon).
* In ''Webcomic/DraconiaChronicles,'' dragons technically DO have males, but they left for parts unknown when the ForeverWar started. New dragons are created by way of cloned, um, seeds applied to an egg. However, CloneDegeneration is in effect, albeit slowed down due to their aeon-long lifespans. Princess Luminia, bred the good old fashioned way (seeds, er, "from the tap" applied to an egg), is more powerful than the Royal Guards, who are all at least a century older than her.
* Despite the fact that the only two to appear to far take on the appearance of a man and woman in order to blend in on Earth, the Fiah in ''Webcomic/TheEnd'' are revealed to all be of a single sex which reproduces by laying eggs parthenogenically.
* ''{{Webcomic/Erfworld}}'': Not surprisingly, [[Series/CharliesAngels Charlie's Archons]] are an all female species. As this world lacks childbirth (or children), and sex appears completely disconnected from procreation, a number of races we've encountered might be all male (or possibly female for some elf variants); we're ''sure'' about the archons.
** If you count unit classifications as racially distinct (this world runs on tabletop strategy physics), there are known all female-vampire subraces, although there are also regular female vampires.
* The Elves of ''Webcomic/FetchQuestSagaOfTheTwelveArtifacts'' are in danger of becoming this, especially with factors both genetic and historical.
* Played with in ''Webcomic/{{Forward}}'': {{Transhuman}} humans still have two ''sexes'', but most of the concept of ''gender'' is lost due to tech advances making body parts swap-out-able and sexism having been overcome, effectively creating a version of humanity where everyone is nonbinary.
* For a very long time, the webcomic ''Webcomic/{{Freefall}}'' left it apparent that all of the robots (whose enormous population forms a major part of the cast) were considered male by default. Only in strip ''[[http://freefall.purrsia.com/ff1500/fc01403.htm # 1,403]]'' does the question finally come up. Disappointingly, the explanation is as stereotypical as it is silly: the robots determine themselves to be male or female based on how much ''talking'' they do.

* Draconians from ''Webcomic/DragonSanctuary'' but it's not so cut and dry. ''Technically'' they're created male, but since they do not reproduce and their gender serves no biological purpose, they do not relate to the concept and their language is entirely gender-neutral. When interacting with other races, some of them adopt he/him pronouns to make things easier while others exclusively use they/them.

[[folder:Web Original]]

* {{Website/Neopets}} has numerous types of faeries with different elements and alignments, all of which are all female. No explanation is ever given.
** And apparently if you try to get into the contests or "Neopian Times" (bi-weekly site newspaper) with a story about a male faerie, it will get rejected solely because of that - the staff doesn't seem to want to endorse any mention of male faeries at all.
* In ''Fanfic/TheReturn'' Succubae are all female [[ViralTransformation regardless of what gender they were as a human]].
* In the works of the (often) Rule34 artist flick, [[https://flick-the-thief.tumblr.com/image/177263368297 orcs are an all-female race]] after a spell cast by the other non-orc species to save themselves (orcs being ExplosiveBreeders), being unable to bear male children. In response, the orcs cast their own spell which ensured that orcs would be able to mate with males of said other species, bearing orc women with some characteristics of the other parent.
* In the ''WebAnimation/MadnessCombat'' setting, there are no known female Nevadeans. While Nevadeans seem to be largely male-presenting and primarly use masculine pronouns, series creator Krinkels has stated that technically they aren't males and are "their own thing".

* All the evil races is ''WesternAnimation/AdventuresOfTheGummiBears'' seem to be like that; Carpies, Trolls, and Ogres. If there are female Ogres, for example, they are never on screen. Troggles (Lady Bane's dog-like minions) were apparently male, yet during the Wedding Episode in which she and Toady were going to marry (due to a LovePotion), Troggles are shown in striper outfit dancing for the Ogres, so... they probably are all female.

* The Gnomes in ''WesternAnimation/GravityFalls'' are all male, at least in [[Recap/GravityFallsS1E1TouristTrapped their first appearance]]. They apparently are supposed to have a single female "queen" which the entire tribe is married to and is presumably the mother of the younger generation, as father-son pairs of gnomes exist, but this seems to usually be a kidnapped human woman or girl. However, a single gnome that appears to be female briefly appears (with no dialogue or plot significance) in "[[Recap/GravityFallsS2E15TheLastMabelcorn The Last Mabelcorn]]".
* ''Franchise/MyLittlePony'' actually made ''more'' sense without the "big brother ponies," when the ponies appeared to be a one-gender race that reproduces via parthenogenesis, resulting in babies physically identical to their mothers. Instead, this seems to be only the case for unicorns and pegasi, as all the males seen in that episode are Earth ponies.
** According to one of the comics, little ponies reproduce by looking in a MagicMirror and wishing for a baby, hence the identical babies. The real question is, where did the babies without an adult counterpart come from? The "old way," maybe?

** Not surprisingly, when Creator/LaurenFaust (who watched the older cartoons growing up) came on board for ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', she promptly made sure to avert this trope - Equestrian ponies come in both genders and reproduce the way Earth mammals do, no ifs, ands, or magic mirrors.
*** Played straight however with [[WingedUnicorn Alicorns]] in that the audience only sees five of them throughout the entire series run, [[Recap/MyLittlePonyFriendshipIsMagicS5E13DoPrincessesDreamOfMagicSheep and outside of an episode taking place inside of a dream]]: not a single one of the Alicorns are ''Stallions''.

** The Smurfs do have some females... three in fact, but at least two of them weren't "natural" members of their species but rather the results of Gargamel creating golem-like beings to infiltrate the Smurfs, and Papa Smurf subsequently making them "real". Smurfs appear to reproduce by [[DeliveryStork stork]]:

** Sassette was made by the three male smurflings [[spoiler:(themselves originally adults)]] wanting to make a companion for Smurfette after she complained about being "the only girl"..

* ''WesternAnimation/{{Droids}}'' just ''might'' have ''one'' female droid among the entire cast. The droid is pink, but the series consistently averts the PinkMeansFeminine rule. If the droid isn't female, then all robots in this cartoon are male.
* ''WesternAnimation/StevenUniverse'': Gems have NoBiologicalSex and [[BizarreAlienReproduction reproduce asexually with machines]], though all of them appear female and use "she/her" pronouns. The only exception is [[TagalongKid Steven]], who's a HalfHumanHybrid. The show's supervising director Ian JQ went so far as to confirm this in a Tumblr post by ''specifically'' [[http://ianjq.tumblr.com/post/113794156834/i-know-that-the-gems-are-sexless-agendered-etc linking to this TV Tropes page]] as a reference, citing the Namekians from ''Dragon Ball'' as another example. [[WordOfGod Creator Rebecca Sugar]] has stated that Gems [[NonHumanNonBinary don't have a gender binary and are more or less genderless from their own perspective]], but roll with being identified as female because they don't really mind or care. As the series has gone on, some of the types gem types introduced are almost or completely androgynous, and a very small number of them even have male voice actors (Snowflake Obsidian and one of the Pebbles, along with one of Steven's fusion).
* The grunts from ''WesternAnimation/TheBrothersGrunt'' all appear to be male.

* While not a concrete example, female Franchise/{{Transformers}} are exceedingly rare. In fact, in some continuities, they don't exist at all. Why a mechanical race even has genders is a frequently-debated topic, as are... how to put this delicately?... [[SlashFic other questions related to gender functions]].

** This is made more confusing by the presence of male pixies in their SpinOff, though it's a different canon. It is also heavily implied that they reproduce...the old-fashioned way...since pixies are shown to have families, including parents, though it also possible that they are only structured into families.

*** It is implied that paladins serve as some [[SpearCounterpart male equivalent]] to the fairies, especially Paladium (who even had wings), but this is never fully confirmed. Likewise, wizards (such as Valtor and the Wizards of the Black Circle) are heavily implied to serve as a male equivalent to [[MageSpecies witches]], but this is also never explained.
* Inversely, all the pixies in ''WesternAnimation/TheFairlyOddParents'' are male.
* ''WesternAnimation/WanderOverYonder'': Subverted with the [[AdorableEvilMinions Watchdogs]], as only males are shown on-screen, but females do exist [[WordOfGod according to the creators]].

* In ''Webcomic/DangerouslyChloe'', the Succubus are a single-gendered species; there is no naturally occurring male equivalent (such as the Incubus). There ''is'' a loophole though, Succubus are capable of changing their gender to male, but Chloe explains this is taboo even for demons, as once a Succubus becomes male not only do they become incredibly more dangerous, but it becomes nearly impossible for them to change back (Teddy becomes a male Succubus/sex demon at one point, and it seems in addition to increased power and strength, his sexual appetite becomes insatiable, moreso than even the typical sex demon).
* In ''WebComic/DraconiaChronicles,'' dragons technically DO have males, but they left for parts unknown when the ForeverWar started. New dragons are created by way of cloned, um, seeds applied to an egg. However, CloneDegeneration is in effect, albeit slowed down due to their aeon-long lifespans. Princess Luminia, bred the good old fashioned way (seeds, er, "from the tap" applied to an egg), is more powerful than the Royal Guards, who are all at least a century older than her.

* ''Literature/LoomingGaia'':
** [[OurNymphsAreDifferent Nymphs]] have NoBiologicalSex and cannot reproduce, but they are all created with a feminine appearance and are referred to by she/her pronouns by default. They can be female-to-male transgender or nonbinary, however.
** All [[SpiderPeople arachne]] are female. They reproduce by mating with male [[GiantSpider silkbeasts]].
** All [[ScorpionPeople skorpius]] are male. They reproduce by kidnapping women and impregnating them with their venom.

* The Fairies of the ''Literature/NottingCove'' series are all female.

* {{Discussed|Trope}} in ''Literature/SpaceCadet''. The Venerians seen are all female, and Oscar is asked if they even have males or if they're this trope. He replies that they definitely have two sexes, but no human has ever seen a male.

* In ''TabletopGame/MagicTheGathering'', angels are always female. (There are two exceptions: one from an AlternateUniverse, and another that [[EarlyInstallmentWeirdness predates the style guide).]] Likewise, [[FemaleAngelMaleDemon demons are male]] when they have an identifiable sex. This is possible because they are not actually biological beings, they're [[MadeOfMagic manifestations of mana]] (white for angels and black for demons).

** Pucks are a male-only species. They boink AnythingThatMoves, but how they reproduce is left a mystery. Since all Pucks look ''identical'', it's been implied that this is some kind of magical cloning (Hobgoblin remarks that Pucks only consider ''themselves'' worth reproducing with).

** {{Subverted|Trope}} with the [[OurDwarvesAreAllTheSame dwarfs]], who seem to be an all-male species, but it turns out that female dwarfs just look -- and traditionally ''act'' -- just like male dwarfs. (Later on, some of the female dwarfs start to push back on this a bit.)

* The Minions in the ''WesternAnimation/DespicableMe'' movies are often assumed to be an all-male race, due to having male names and such, though some of them aren't afraid of cross-dressing when disguising themselves. Though it is possible they have NoBiologicalSex and just have male names.

** While most [[OlympusMons Legendary Pokémon]] are genderless, a few of them do have gender. Latios and Latias are one of the first of those Legendary Pokémon with a gender, though Latios is always male while Latias is always female as they are [[BizarreSexualDimorphism implied to be members of the same "species"]]. The Forces of Nature (Tornadus, Thundurus and Landorus) are all male.

* In ''VideoGame/BugFables,'' ants and eusocial bees are almost entirely female--[[GeniusBonus just as in real life.]] A single drone ant appears, and the male bee who appears is a carpenter bee, which is not a eusocial species.

* ''WebOriginal/LoomingGaia'':

* In ''Monster Girl Quest'', all the monsters are female, and survive by raping human males. Early on, we find out that this isn't their fault: The humans' goddess has forbidden sexual intercourse with monsters. Again, they're all female, so it's just a slow form of genocide. This goes deeper than genetics to the spiritual "essence of monsterhood"; even artificial and spontaneously generated species are all female, and the rare male children of monsters are genetically human. This eventually gets explained: the goddess who created the first monsters wanted to force some degree of coexistence with humanity as a way of balancing the energies maintaining creation. At other time periods it's worked out.

** Gorons all identify as male, referring to each other as "Brother." This could be the case of identity rather than biological sex or they could be {{Truly Single Parent}}s, since all cases of child Gorons seen in the series only have fathers and mothers are never mentioned. The [[Manga/TheLegendOfZeldaOcarinaOfTime1999 manga]] of ''Ocarina of Time'' has a few female Gorons that are only visibly different due to [[TertiarySexualCharacteristics long eyelashes]]. ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]'' references this ambiguity by showing that two Goron men have been allowed in the women-only Gerudo Town, and absolutely no one knows why this is, least of all the Gorons. A throwaway line in the Japanese version implies that the Gerudo consider the Gorons honorary women.

* All the evil races is ''WesternAnimation/AdventuresOfTheGummiBears'' seem to be like that; Carpies, Trolls, and Ogres. If there are female Ogres, for example, they are never on screen. Troggles (Lady Bane's dog-like minions) were apparently male, yet during the Wedding Episode in which she and Toady were going to marry (due to a LovePotion), Troggles are shown in striper outfit dancing for the Ogres, so… they probably are all female.
* The Amazonians from ''WesternAnimation/{{Futurama}}'', who ousted their male population under the compulsion of the mysterious Femputer. The other men died from [[OutWithABang crushed pelvises from Snu-Snu]].
* The Gnomes in ''WesternAnimation/GravityFalls'' are all male, at least in their first appearance. They apparently are supposed to have a single female "queen" which the entire tribe is married to and is presumably the mother of the younger generation, as father-son pairs of gnomes exist, but this seems to usually be a kidnapped human woman or girl. However, a single gnome that appears to be female briefly appears (with no dialogue or plot significance) in "The Last Mabelcorn".

* ''WesternAnimation/TheSmurfs'' do have some females... three in fact, but at least two of them weren't "natural" members of their species but rather the results of Gargamel creating golem-like beings to infiltrate the Smurfs, and Papa Smurf subsequently making them "real". Smurfs appear to reproduce by [[DeliveryStork stork]]:

* ''[[WesternAnimation/{{Droids}} Star Wars: Droids: The Adventures of R2-D2 and C-3PO]]'' just ''might'' have ''one'' female droid among the entire cast. The droid is pink, but the series consistently averted the PinkMeansFeminine rule. If the droid isn't female, then all robots in this cartoon are male.
* ''WesternAnimation/StevenUniverse:'' Gems have NoBiologicalSex and [[BizarreAlienReproduction reproduce asexually with machines]], though all of them appear female and use "she/her" pronouns. The only exception is [[TagalongKid Steven]], who's a HalfHumanHybrid. The show's supervising director Ian JQ went so far as to confirm this in a Tumblr post by ''specifically'' [[http://ianjq.tumblr.com/post/113794156834/i-know-that-the-gems-are-sexless-agendered-etc linking to this TV Tropes page]] as a reference, citing the Namekians from ''Dragon Ball'' as another example. [[WordOfGod Creator Rebecca Sugar]] has stated that Gems [[NonHumanNonBinary don't have a gender binary and are more or less genderless from their own perspective]], but roll with being identified as female because they don't really mind or care. As the series has gone on, some of the types gem types introduced are almost or completely androgynous, and a very small number of them even have male voice actors (Snowflake Obsidian and one of the Pebbles, along with one of Steven's fusion).

* ''Anime/MazeMegaburstSpace'': Fairies are all female, and reproduce with human men on the one day when they're human-sized.

* In ''Literature/TheBFG'', all [[OurGiantsAreBigger Giants]] are male; the BFG explains that giants simply come into being.

* ''Literature/TheWitches'': All [[WickedWitch Witches]] are female (though they don't interbreed with humans and are all evil), but as they are demons and not humans, it doesn't particularly matter. The book also mentions barghests and ghouls to be all-male.
