'''Kevin Murphy:''' Well we're over the PlanetOfTheApes, approaching ThePhantomPlanet, right near the [[OurVampiresAreDifferent Planet of the Vampires]] which is right across from the [[LostWorld Prehistoric Planet]].

->'''Kaidan:''' I haven't spent much time with krogan before, Wrex, and I have to say, you're not what I expected.\\
'''Wrex:''' Right. Because humans have a wide range of cultures and attitudes, but krogan all think and act exactly alike.
-->--''MassEffect''

On their WagonTrainToTheStars, our intrepid heroes come across a planet with a single defining characteristic. Everybody is a [[RobotRollCall robot]], or a [[LovableCoward coward]], or a gangster, or a ProudWarriorRaceGuy, or a CorruptCorporateExecutive, or wearing a hat.

Earth itself is sometimes portrayed as a Planet Of Hats. The defining human characteristic is often [[HumansAreSpecial "pluck"]] or [[HumansAreWarriors "sheer cussedness"]] and sometimes even [[LampshadeHanging "diversity"]], though [[HumansAreBastards "bastardom"]] or is common in more misanthropic works.

Writers love to use the hat planet to represent controversial issues in society whenever they can. This way the show's characters can take a thinly disguised public stand on an issue that the network execs would otherwise consider too taboo to openly discuss. We can't have our heroes discussing euthanasia, but should they stumble across a Planet Of Hats where everyone who gets sick is put to death, then it's okay. Eventually the plots will run out with an entire race of identical people so one or more of the species will have their hat fall off, declaring MySpeciesDothProtestTooMuch. For maximum typing, the characters can also be physically uniform, as in PeopleOfHairColor.

The PlanetOfHats may also be an unintended result of a CharacterExaggeration -type PlotTumor applied to an ''entire race'', when the audience had previously only seen a single representative who the writers now wish to market.

See also RubberForeheadAliens, IntelligentGerbil, ScaryDogmaticAliens. May result because ApathyKilledTheCat. SeriousBusiness is what happens when the show's setting gets a hat. This trope in itself is a good example of UnfortunateImplications and SciFiWritersHaveNoSenseOfScale. See SingleBiomePlanet when the planet is unnaturally uniform physically.

!!Examples

[[foldercontrol]]

[[folder: Anime ]]

* In the ''{{Cowboy Bebop}}'' episode, "Mushroom Samba" (itself the name of [[MushroomSamba another trope]]), the crew of the Bebop finds that the {{terraform}}ed moon Io has developed a culture apparently inspired by 1970s {{Blaxploitation}} films.
** Bebop used the different planets as either FantasyCounterpartCulture or a planet of hats. Venus was US-run, while Mars was Asian, the Jovians were mostly European, and Earth was SE Asia.
** Mars is arguable - they seem to be a regular cultural kitchen sink - quite understandable, since it's supposed to be the new center of human civilization. There's such things as Moroccan Street next to Manhattanesque neighbourhood, while Chinese Triads hold power in other parts. Callisto, on the other hand is a stereotypical Russian setting, modelled after a popular perception of a Siberian industrial city.
* In ''[[KinosJourney Kino's Journey]]'', each individual country is a separate PlanetOfHats, such as a country devoted to nothing else but the construction of a tower or is inhabited by people who do nothing but secretarial work.
** Most amusingly is the town who doesn't have a hat, and is trying desperately to get one. They show off some different 'ancient tradition' to every traveler to come by. Kino remarks that this ''is'' their hat.
* In the manga ''{{Aria}}'', Mars has terraformed into a water covered planet. Earth obviously took the liberty to turn it into the Venice planet; from the architecture to the gondola-use.
** In fact, the abundance of water is an accident (They found more water than they thought); and only a town is a reconstitution of Venice, while the rest seems fairly different. It is specifically mentioned that different Earth cultures settled/adapted individual islands to replicate their own culture (explaining how Akari and Alicia can row from "Venice" to "Japan" to visit a famous shrine).
* In the Manga ''TsubasaReservoirChronicle'' by CLAMP, the characters must visit different worlds in search of Princess Sakura's feathers. Roughly every world they visit will be a Planet of Hats (although some of them aren't as easy to notice).
* In ''{{Vandread}}'' the two main planets are Taraak (the planet of men), a barren world where the locals are concerned with things like uniforms, practicality, appearing manly, and eating nutrition pellets (think hamster food), and Mejere (the planet of women), which looks like Las Vegas and has locals concerned with appearing nice, who eat foods that are basically dessert.
** There's a darker side to this as well, as every inhabited planet was marked by a unique physical trait [[spoiler: representing which organ was supposed to be harvested by Earth. Taraak and Mejele were male and female reproductive organs respectively.]]
* Not as major as other examples, but the people in ''ScrappedPrincess'' seems to suffer bad artist hat.
* The three Invading Countries (actually planets) from the second season of ''MagicKnightRayearth''. Autozam is all about the [[MagiTek mental power-based technology]], Fahren is a thinly-veiled FantasyCounterpartCulture for AncientChina, and Chizeta's culture is entirely ArabianNights-based.
* Common in ''GalaxyExpress999''.
* Used quite literally in Panyo Panyo ''DiGiCharat''.

[[/folder]]

[[folder: Comic Books ]]

* ''[[TopTen Top 10]]'' (by comic book genius AlanMoore) takes place in a city where everyone is a superhero or some other "science hero" trope. This does have lots of room within it, however, as the titular team has a talking dog in an exoskeleton, the world's only Yazidi superhero, and a sarcastic Mazinger Z, amongst others. Did I mention it's a [[TheyFightCrime police procedural]]?
* In the ''LegionOfSuperHeroes'', most planets are like this, with their "hat" being related to their super-power; Naltor, planet of precogs, Titan, planet of telepaths, Colu, planet of geniuses, et cetera.
** They also have two characters from Winath who (at least some of the time) share a superpower, but that's not Winath's hat- twinning is normal there and in some media, the whole planet is devoted to farming.
** Ultra Boy comes from Rimbor, which is The Planet Of Dark Alleys and Biker Gangs.
** This is all brilliantly justified in [[http://dc.wikia.com/wiki/Legion_of_Super-Heroes_Annual_Vol_4_2 Legion of Super-Heroes Annual #2]], which shows that all of these planets were specifically colonized a thousand years earlier by advanced humans with similar power-sets after ''Invasion!'' happened.
* Also occurred at least once in a {{Superman}} comic in which Jimmy Olsen is transported to the Planet of the Capes. [[http://www.superdickery.com/index.php?option=com_content&view=article&id=251:planet-of-the-capes&catid=28:superdickery&Itemid=54 I kid you not]].
* Lobo from 'DC Comics' occasionally encounters hat planets, such as planets made entirely from highway (in the Lobo comic series), a vacation planet (The Last Czarnian mini-series), a planet populated by religious fundamentalists who immediately explode upon contact with any infidels by triggering an apparently inherited power through pushing down their head onto their shoulder.

[[/folder]]

[[folder: Film ]]

* Not quite as obvious in ''StarWars'', but quite present: all Twi'lek girls are exotic dancers, all Hutts are gangsters, all Bothans are spies, all Ithorians are pacifists, etc. (see also SingleBiomePlanet). Of course, almost any species, Hatted or not, may show up as a Jedi (Even a Hutt or two), and there are numerous other exceptions. In recent years, some writers grew tired of these stigmas and began [[LampshadeHanging lampshading]] and subverting them — for example, showing a couple of Ithorian criminals in one of the KOTOR comics and claiming that Ithorians "stay all peaceful and polite" by "throwing guys like these out". In many cases, the hats in Star Wars seem to have been placed by the fans or EU writers. The films indicate that at the very least, nearly every species in the galaxy has senators. Gungan society shows a diversity, featuring overbearing rulers, knuckleheaded outcasts, and courageous soldiers. Of course, they do all seem to hate and fear Jar-Jar...
** If hating Jar-Jar Binks fits this trope, then the entire Star Wars galaxy ''and'' all of RealLife would wear the hat.
** [[KnightsOfTheOldRepublic KotoR]] lampshades the sharing of hats (Mercenary/Bounty Hunters) between 3 races at one point, with one of each race pointing out the differences between them.
*** Also in KOTOR, one twi'lek on Taris was an entrepreneur in the upper city who commented that her business doesn't do as well as it should because people there expected her to wear the dancer hat... or something... it's been awhile since I played that game.
*** KOTOR does, however, play the Wookiee life-debt hat absolutely dead straight with Zaalbar, and Hanharr ''has'' one but is filtering it through his AxeCrazy ChaoticEvil psychosis into an obsessive desire to kill the object of said life debt.
**The Expanded Universe also subverts/averts the Hats, having Twi'leks reveal that they have a unique culture, complete with their own Proud Warrior Sect. Not to mention a Twi'lek who put the 'slave dancer' phase far behind her, and a Bothan who is surprisingly honest. At least one book mentions that Jabba the Hutt was a common smuggler before being a Mafia Don, which is almost the Hutt's hat.
*** Isn't there a Twi'lek on the Jedi counsel in the new movies?
*** Corellians as NeverTellMeTheOdds: Lampshaded regularly, particularly Corran Horn and CorSec. [=Twi'leks=] as exotic dancers: Averted once, with Aayla Secura. Wookiee life-debt: Averted in KOTOR. Mandalorians as cold-hearted mercenaries: Both played straight and averted by any of Karen [=Traviss's=] work. Evil Sith were averted by the Jennsaarai. Even the New [=Republic's=] "good guy" image was averted in the Jedi Academy trilogy, when they debate whether or not to turn the Sun Crusher on TheEmpire.
** Well the Twi'leks did [[AllThereInTheManual sell themselves into slavery in order to get off Ryloth (as they lacked starships)]] so that hat is at least semi-justifed.
** The Expanded Universe has even given us a Hutt ''Chancellor of the Republic,'' who is noted to have been a fair, honest, popular leader.
*** There's also been somewhere (in ''The Planet of Twilight'') a Hutt Jedi called Beldorian or Beldorion (darksider, but still greatly untipical for a Hutt).
** One of the novels, [[XWingSeries Starfighters of Adumar]], takes place on a (human-occupied) planet whose Hat seems to be reverence for starfighter pilots combined with blood sport and melodrama. In time we get to see that these traits are more a specific ''country's'' Hat, and intelligent people from said country can be made to doubt their convictions with relative ease.
** Interestingly, some of the human planets get Hats too. Especially Corellians (the planet of NeverTellMeTheOdds) and Alderaanians (philosophical pacifists).
*** Tatooinians are all excellent pilots. Rogue Squadron actually has a [[TheWesley sixteen-year-old Tatooinian]] as Rogue Five. Lampshaded by the fact that when he wants to ask Corran a question about inter-species relationships, Corran thinks he does't know what sex is.
* Every member of Yoda's species is a wise Jedi master; all 4 of them.
* The Disney film ''{{Meet the Robinsons}}'' contains, as an AlternateUniverse, a literal PlanetOfHats -- where all humans are controlled, as zombies, by intelligent, spider-like bowler hats.
** The evil hats have appeared in other Disney works -- at least one episode, possibly two, of DarkwingDuck, for example.
*** Does Disney know something that we don't? Food for thought.
*** I know I'll hesitate before I ever don those mouse ears again...
*** It's possible they got it from the children's novel ''When the Tripods Came'' (and sequels), in which the titular aliens issue Caps that control people's minds.
* In ''MomAndDadSaveTheWorld'', the title characters get kidnapped by (and save the world from) an EvilOverlord from a planet where the hat is... [[RalphWiggum mind-boggling amounts of stupidity]]. As an example, one of the deadliest weapons on this world is called the light grenade, which instantly disintegrates whoever picks it up. And how does this [[TooDumbToLive decimate an entire army]]? It says [[SchmuckBait "Pick Me Up"]].
* ''TheAmericanAstronaut'' has the Venusians, which are all SouthernBelle and the people from Jupiter who are all miners, the later is justified since it's implied they are hired from all over the galaxy.
[[/folder]]

[[folder: Literature ]]

* Nations characterized by a single trait have been a staple of travelogue-style fiction [[OldestOnesInTheBook for centuries]]. The academics-obsessed people of Laputa in [[GulliversTravels Gulliver's Travels]] are a good example.
** And the ancient Greek tales of Hyperborea, {{Atlantis}} and other allegorically intended foreign lands.
* Semi-subversion: Janet Kagan's ''Hellspark'' is a multiple-culture universe where each of the cultures has a single quirk -- one considers feet obscene, one duels at the drop of a hat, one considers telling the truth (speaking ''accurately'') a basic requirement, etc... and each of these people are individuals who incorporate their cultural quirk into their individuality.
* LarryNiven's ''KnownSpace'' deals with this trope. Pierson's Puppeteers are [[LovableCoward cowards]] to the point that only insane specimens are willing to deal with other species (but as their [[MeaningfulName name]] implies, their ''real'' hat is [[ManipulativeBastard Manipulative Bastardry]].) Kzinti are all {{Proud Warrior Race Guy}}s, and humans may or may not have a trait for genetic luck. Humans are also apparently obsessed with sex; in ''Ringworld'', the puppeteer Nessus says to Louis and Teela, "No known species copulates as often as you do", and ''The Ringworld Engineers'' features many species with the same ancestry as humans whose politics revolves around ritual inter-species sex. Further, at various points in the series, Niven will go into the details of how these ''hats'' are worn, via the various mechanism that produced the human traits, and the evolutionary imperatives that effect the ongoing makeup of the various species. At one point in ''Ringworld'', a kzin sets a human off on a logical analysis of the instability of Kzinti aggression in the context of an enemy race that they can't easily beat. Whether this is a LampshadeHanging or a [[JustifiedTrope justification]] is left as an exercise for the troper.
** There are plenty of exceptions of course. The Kzinti have the least, but that's justified with them genetically engineering themselves into a 'heroic' race. They were at best bronze age technologically when taken by another species to use as troops. They rebelled and overthrew their masters, using their technology with most of them not truly understanding it. They tinkered a hell of a lot with their own genome, with one of the offshoots making their women non-sentient and playing with their sex drives and aggression. The Puppeteers don't even have sex as we understand it, reproducing with a female of a separate species that actually gestates the young until the child eats its way out...
** Pak Protectors wear the VillianSue hat, and human Protectors wear the CanonSue hat. To be transformed into a Protector is to become the ultimate soldier, strategist, scientist and engineer, able to solve almost any problem and beat almost any opponent.
* Justified on ''TheLittlePrince'' since every planet is inhabitated by exactly one person.
* ''{{Animorphs}}'' mostly averted it (Hell, even the ''Yeerks'' are morally conflicted about [[AlienInvasion what they do]]), but book 26 had the Iskoort, whose Hat was guilds -- there was (in order of introduction) a Trader Guild, a Criminal Guild, a Warmaker Guild (though it quickly becomes clear the Iskoort were not cut out for combat), a Superstition and Magic Guild, a Shopper Guild, and even a "News, Gossip, and Speculation Guild." And all the Traders were the most annoying salesmen imaginable. (The others were annoying, too, but they ran into Traders the most.)
* The [[TheHitchHikersGuideToTheGalaxy Vogons]] are a race of {{Obstructive Bureaucrat}}s.
** And awful poets.
* This trope dates back to at least ''{{The Skylark of Space}}'', the very first SpaceOpera. It was taken to such an extreme that the heroes would cheerfully [[ValuesDissonance commit genocide]] on [[AlwaysChaoticEvil species they disapproved of]], rather than try to change them.
* In the comedy science fiction stories about the {{Hoka}} written by PoulAnderson and GordonRDickson, the Hokas' "hat" is that they are entranced by fiction. Give them a story and they will start to live it out, believing (or at least acting) as if they are in it. They have whole cities based on various periods of human history, with Ancient Rome, Victorian England, American Wild West and other places. One of them believes he is Napoleon and has an entire city of Hokas willing to follow him as leader of "France". Actually, a better way of saying it is that their hat is following tropes, as they tend to act out the trope more than reality. Luckily, they are non-violent, so they tend to just fake the wars and other violent parts.
** The trope also occurs in GordonRDickson's Childe Cycle, better known as the Dorsai series. Humanity has separated in various splinter cultures who specialize in one area. Dorsai have the best professional soldiers. Newton and Venus have the best scientists. Coby the best miners. The Exotics the best psychologists and philosophers. The Friendlies focus on religion, as well as cheap but poor mercenaries. The trope is justified in the larger frame of the Cycle.
* The alternate worlds or "planes" in ''Changing Planes'' by [[UrsulaKLeGuin Ursula K. Le Guin]] are often like this; each one features a more-or-less humanoid alien race with a special ability, psychological/biological quirk, or universal tradition -- such as sharing dreams, seasonal migrations, near-constant anger, becoming silent at adulthood, and extreme devotion to apparently meaningless architectural projects.
* In the ''{{Belgariad}}'' series of novels by DavidEddings, each of the nations of the West has its own hat. To a first approximation, based on the characters encountered: All Sendars are farmers, all Drasnians are spies, all Tolnedrans are merchants, all Chereks are Viking warriors, and all Nyssans are drug-addicted poisoners.
** Most of the 'hats' are actually fantasy archetypes based on Earth cultures -- the Chereks are Vikings ToTheMax, the Algars are the Mongols likewise, the Drasnians appear to be a Renaissance Italy stereotype transplanted into a different geographical setting, the Tolnedrans are based on the Roman Empire (hence both their mercantile aspect ''and'' their obsessive road-building and disciplined legions), the Arends are medieval high chivalry myths taken to the point of self-parody, etc. The unflappable demeanour, their courtesy, and the general obsession with propriety of the Sendars seem to be more English than anything.
**** The Eastern nations started out as pretty hatty, too. But then, they were under the control of an insane god for millenia. Eddings [[strike:recycles]] revisits those themes in the Elenium and Tamuli novels: All Styrics are self-pitying magicians, all Atans are warriors, All Tamuli are polite to a fault, etc.
***** That the Angarak nations are hatty is justified, in that the tribes of Angarak originally were the CASTES of Angarak, and that Torak mistook their differences for tribal rather than professional distinctions after being away doing god-stuff for a couple thousand years.
* In the novel ''Design for Great-Day'' by Alan Dean Foster and Eric Frank Russel, a spiderlike species is mentioned whose hat is... hats. [[NiceHat Nice ones]].
* Both used and averted in ''TheEdgeChronicles''. All of the Slaughterers are hunters and butchers, all of the shrykes are slave-trading warriors, and all of the trolls are lumberjacks. This even extends to occupations: the Leaguesmen are corrupt, the Sky-Scholars are evil, and the Earth-Scholars and Sky Pirates are good. However, oakelves, goblins, waifs, and (of course) [[strike:humans]] [[CallAHumanASmeerp fourthlings]] can be anything, and quarter-masters are either traitorous or fiercely loyal (sort-of hat).
* In L. Ron Hubbard's ''BattlefieldEarth'', the Selachee, a race of sharks who have feet, can "live anywhere, breathe any atmosphere and eat anything," and while they did have Selachee who are engineers and other professions, their planet's exclusive profession is banking.
* In CSLewis' [[{{Narnia}} The Voyage of the Dawn Treader]], the entire race of Dufflepuds play CaptainObvious, with such astute observations as water is powerfully wet.
** Although this is justified in that "the entire race" is one small tribe of (originally) dwarfs who were given to the wizard Koriakin to oversee in order to teach him humility, so their stupidity is presumably a design feature. (Koriakin is literally a star, on enforced sabbatical for some fault that Man is not meant to know about.)
* In AlanDeanFoster's series ''The Damned'', all of humanity wears the BloodKnight hat once an interstellar war lands in our laps. And it's a good thing, too, because every other species in these novels either wear the Programmed For Pacifism hat or the Reluctant Clumsy Warrior hat, and being good at killing things is our only hope to survive in the face of technological superiority. Well... that and being immune to telepathy.
* {{Lois McMaster Bujold}}'s Barrayar books are made of this trope. The Beta Colony wears the "uber tolerant libertine" hat. The Jackson's Whole wears the "WretchedHive" hat. Cetaganda wears TheEmpire hat. And the titular Barrayar wears the ProudWarriorRace {{Ruritania}} hat.
* Tanya Huff's ''Valor'' series has the Taykans and the Krai whose hats are sex and food respectively.
* John Varley's short story "The Barbie Murders" features a cult of humans nicknamed "The Barbies" who are obsessed with conformity. They have each been modified to look and sound identical, down to the last tiny detail. They have no names or personal identities, and each takes responsibility for the actions of all the rest. This makes finding a murderer in their midst rather trying.
* In the ''ChroniclesOfThomasCovenant'', the Haruchai are a race of stoics. The Insequent are a race who WalkTheEarth in search of knowledge. The Elohim wear a selfishness hat. All the Ramen (people from the Plains of Ra, not noodles) care about are their horses. The Stonedownors are obsessed with stone while their cousins the Woodhelvins are obsessed with trees.
* EndersGame has planets that were colonized by a single religion or country, and for some reason the FridgeLogic was the idea to encourage diversity of humans among the stars. Never mind the fact that if, say, all the other planets got destroyed, humanity could end up being represented by the single planet of hats- from what we've seen, Chinese Confucists, Catholic Portuguese, or the small society that lives on the planet of pig-tree freakbabies. It's also never stated how many planets of Chinese Confucists are out there, so once that one goes...
** Looking at the worlds that ''don't'' have single religions or cultures (ie. globalisation taken to extremes), it seems to work well enough in-universe.
* JerryPournelle's CoDominium is similar for a [[JustifiedTrope justified reason]]; colonies are expensive, and require sponsors who obviously choose who populate them. [[{{Eagleland}} America]] and [[InSovietRussiaTropeMocksYou Russia]] have filled the galaxy with clones of themselves, and every industrial power has at least one colony; all are meant to be examples of the superiority of their given culture. Religious and political nutcases with sufficient funds have attempted to do the same, but are often subject to the titular Amerusski Pact dumping criminals on them, meaning that almost every planet that isn't populated by Hats is a CrapsackWorld.
* Depicted in TheHitchhikersGuideToTheGalaxy as one of the ways a civilization can be wiped out. The example given is a planet's entire economy being dominated by shoe stores.
* Walter Moers applies the principle to several cities in his Zamonia novels, most notably Bookholm (everything revolves around books) and Sledwaya (everything revolves around illness)
* This is a common theme in Robert Asprin's MYTH series, with the characteristic of residents often being puns on the name of their "dimension." For example, residents of Deva (Deveels) are all aggressive merchants, while male residents of Trollia are trolls and female residents, trollops.
* In the ''To The Stars'' trilogy by Harry Harrison, [=EarthGov=] has not only terraformed {{Single Biome Planet}}s, they've also created a unique culture for each in order to maximise their control. For instance the agricultural planet the protagonist has been exiled to in "Wheelworld" is populated entirely by peasants and mechanics, ruled by a group of autocratic Familys.
* In old science-fiction novel [[http://www.gutenberg.org/etext/18492 ''Star Surgeon'']] by Alan E. Nourse, Humans have the hat of being doctors, to the point that Earth is called "Hospital Earth". Apparently nobody else ever really got into the whole "cut people open to make them better" thing. (At the time it was written, open heart surgery was [[PhlebotinumDuJour a new, exciting thing]].)
* In [[http://www.webscription.net/10.1125/Baen/0671318616/0671318616.htm Pandora's Planet]], the [[AlienInvasion Alien Invaders]] are dull and gullible enough compared to humans that once we start going out and proselytizing they become more convinced than the proselytizers. A whole planet briefly bans everything artificial. Mention is made of a low-gravity world colonized expressly for the purpose of horse racing.
* ''E.T.: The Book of the Green Planet'', the sequel novel to ''[=~E.T. the Extra-Terrestrial~=]'', implies that all the members of E.T.'s unnamed species are botanists, since they can all communicate telepathically with plants.

[[/folder]]

[[folder: Live Action TV ]]

* The ''StarTrek'' series are actually the prime examples of this trope, nearly every species having one defining trait:
** "A Piece of the Action" is interesting because the culture's true hat was mimicking others -- their entire society had been built around a book about 1920s gangsters in Chicago.
*** As revealed by the comics, after being visited by the Enterprise they experienced a cultural revolution and became an Original Series StarTrek planet.
** The Vulcans are [[StrawVulcan all logic all the time]].
*** Brilliantly subverted in the Expanded universe book "Spock's World", where logic is shown to be the state religion, and emotional control a natural extension of the planet's telepathy. A shame that it was relegated to discontinuity by Star Trek V. Star Trek never was good at controlling the Expanded universe's continuity.
** The Klingons are [[ProudWarriorRaceGuy all war all the time]]. (They'd tell you their true hat is honor, but [[MySpeciesDothProtestTooMuch that's not what you get in practice]], to protagonist Klingon Worf's disillusionment.)
*** Moq'bara is the martial art practiced by Klingons everywhere, because while a peaceful society like the Federation will have hundreds of styles ranging from kung fu to boxing, a warrior culture will clearly only have one.
** The Romulans are all intrigue all the time.
** The Ferengi are [[YouFailEconomicsForever all profit all the time]].
** The Cardassians are all {{Magnificent Bastard}}ry all the time.
** Tellarites "do not argue for reasons, they simply argue." Spoken by a member of a species that apparently doesn't have such great relations with the Tellarites, but eventually proven true once we get to meet more. Negotiations are often opened by trading insults.
** Conformity as a Hat has been done a few times, most notably with the Borg.
** Cheron in "Let That Be Your Last Battlefield" is (or rather, was), supposedly, a planet of racists. (''They'' are black on the left side. ''We'' are black on the right side!)
** The Deltans' hat was going to be [[{{Miss Yo-Yo Knickers}} sex]], but that WallBanger in the making [[AbortedArc thankfully never came to pass]], as the "Phase II" series never happened. However, Lt. Ilia from the first movie (adapted from what was to be the pilot; Ilia was to have been a main character) does mention having taken a vow of celibacy before coming aboard.
*** Which would make them [[NotSoDifferent different from modern humanity]] [[TakeThat how?]]
**** Or ancient humanity, for that matter?
** Taking place clear across the galaxy from these others, ''StarTrekVoyager'' has its own hat species, such as the Kazon (society revolves around infighting between the various rival groups), the Vidiians (society revolves around medicine and organ-stealing due to the disease they have), the Hirogen (society revolves around [[TheMostDangerousGame "the hunt"]]), and Species 8472 (society revolves around eradicating lesser, "weak" species.)
*** At least the Vidiians claim to have had a very different culture before the phage came.
** Humans don't quite have a Hat, and -- especially in the Gene Roddenberry days -- were sort of the anti-hat: Having finally gotten it right, humanity's made a perfect future for itself, finally free of the undesirable qualities that some of the other species represent.
*** Then again, being "perfect" eventually ''became'' humanity's hat, until the DS9 era, where that hat was rather rudely yanked off, set on fire, and thrown into a wood chipper.
*** On ''StarTrekEnterprise'', Vulcan Ambassador Soval complains at length about humanity's lack of a Hat: ''"Of all the species we've made contact with, yours is the only one we can't define. [...] One moment you're as driven by your emotions as Klingons, and the next, you confound us by suddenly embracing logic!"'' He goes on to explain that pre-logic Vulcans were similarly hatless in a way that now scares them.
** The ExpandedUniverse novel ''How Much for Just the Planet?'', by [=~John M. Ford~=], features a world whose hat is ''comedy routines''. [[spoiler:It eventually turns out that they're just putting it on to keep their visitors off-balance.]]
** An alien on Voyager once used this trope to describe different species - his own species' hat was an inherent understanding of languages, while humanity's was "a great generosity of spirit." However, [[spoiler: it turned out he was buttering the Voyager crew up so he could get revenge on them for indirectly causing his own species' extinction]].
** The episode "Patterns of Force" has the Nazi Planet. (Not their native hat, it was imported by a WellIntentionedExtremist historian from Earth).
** The Yridians are all information dealers.
** The Denobulans are all doctors.
** The [[StarTrekNewFrontier Redeemers]] are all religious fanatics.
** As noted above, there are actually several episodes with planets whose inhabitants made their hat by copying something from Earth -- gangsters, Nazis, ancient Greeks ...
** The Redeemers of Tulaan IV in ''StarTrekNewFrontier'' are the most prominent hat-wearers in the series. Their hat is extreme religious fanaticism. Think the worst of the Christians during the Inquisition, the worst Muslim fundamentalist terrorists, every cult you can think of, mix them up, and then crank them to eleven, and you might have a sliver of the fanaticism that the Redeemers have.
** A ''Star Trek'' spinoff novel lampshaded this one by explaining that on most planets, war and oppression and genocide have had a homogenizing effect on sentient species. Humans figured out how to live together peacefully before that happened to them. As a result, Earth has a far greater range of cultural and ethnic diversity than can be found on most other planets.
* In ''[[BabylonFive Babylon 5]]'', the Narn start off as the Proud Warrior Race, the Minbari as Elves, the Vorlons as Mysterious Elders and the Centauri as the declining Roman Empire. The Narn become Warrior Poets, the Minbari lose all hats due to a civil war, and the Vorlons gain a Law hat. The Shadows also happen to gain the Chaos hat, the Drazi steal the Proud Warrior Race. The uniformity of the alien cultures compared to humanity is lampshaded in the episode "The Parliament of Dreams," where each of the major races puts on a display of their global religion, while Sinclair arranges dozens upon dozens of people to represent humanity's multitudes of religions. Ultimately humanity's "hat" is explicitly defined (by Delenn) as community-building -- humans automatically and unthinkingly weave together disparate groups into communities.
* ''{{Lidsville}}'' takes the concept to its furthest extreme -- a world entirely populated by actual anthropomorphic talking hats.
* ''{{Farscape}}'' had an episode on the planet [[MeaningfulName Litigara]] where roughly 80% of inhabitants were lawyers and the remaining 20% servants who ran the various non law-related services.
**It could be said it was a planet of balacavas since that's what the lawyers (which most of the population dreadfully enough were) always seemed to wear. Also the Judge wore a hat that was a mix between a sombrero and a dinner plate and whose uniform (and hat) was a colour that looked like Dolores Umbridge had picked it out.
* Parodied in the new ''DoctorWho'' season four opener: Donna brings a hat box on the Tardis... "Planet of the hats? I'm ready!"
** This is then referenced in a short strip in ''DoctorWhoMagazine'', where the good and bareheaded [[DoctorWho Doctor]] is set upon by hatted aliens ("His head is naked!") with Donna looking smug and hatted nearby.
** Also subverted in Aliens of London/World War Three where the Slitheen reveal that it is not their species, but their surname. As opposed to representatives of their race, they're actually [[EvilIsOneBigHappyFamily a family of crime lords]] and wanted criminals in their culture.
* The Twelve Colonies of the new ''BattlestarGalactica'' occasionally fall into this, in function if not in populace. Aerilon was the breadbasket of the colonies, and everyone from it is perceived to be some sort of hick (which is why Baltar adopted a more upper class accent). The Gemenese believe in the literal truth of scripture. Sagittarons are downtrodden, and mad about it. Taurons are stoic and traditional, and have a mafia equivalent. Capricans have it made - their planet is the center of art, culture, science, and politics. There is, however, no physical look specific to the people of any planet. Hopefully, this means that SingleBiomePlanet is avoided.
* In the ''{{Stargate SG-1}}'' episode "2001", the Aschen are described as: "They don't get excited in general, General. It's like an entire planet of accountants."
** In fact, particularly in the earlier episodes, nearly every planet the SG-1 team visits is based off of a particular human culture. There are the Middle Ages, the Norse, the Greeks, the future, and, of course, the ancient Egyptians, among others.
** In ''StargateAtlantis'', the Wraith are apparently a race, consisting solely of warriors who live to eat. Their society is never shown even once.
*** Of course, the Wraith have insect qualities, complete with queens and (literally) faceless drone soldiers, so this isn't totally unreasonable. Meanwhile, however, we also get a Star Trek-ish 1940s Planet, complete with snazzy uniforms.
** {{Stargate SG-1}} also had the Nox, who in addition to having extreme pacifism and irritating arrogance as their 'hat', were also a literal PlanetOfHats: They were nothing more than humans with BizarreAlienBiology and funny hats.
** Earth has its own hat: GenreSavvy. SG-1 is the most GenreSavvy of them all, but most other minor characters show at least some signs of this trait.
* ''RedDwarf'' had Rimmerworld, a planet populated by Rimmer clones. The population idealized the core aspects of Rimmer... which happens to be being cowardly, backstabbing, snotty, arrogant, and power hungry. Those that deviated were hunted down and executed.
* The Neighborhood of Make-Believe segment of ''Mister Rogers' Neighborhood'' deconstructed this trope, in a child-appropriate way, with alien visitors from the Planet Purple. Everyone from this planet has purple skin and hair, they dress in identical purple clothes and speak in a monotone voice, and all the boys are named Paul and all the girls are named Pauline. They were used to illustrate how boring the world would be if everyone was the same.
* Largely averted in PowerRangers, as alien cultures rarely seem to reflect aspects of earth society, the exception being planet Onyx. Its hat is the WildWest, existing largely as a place for the [[BadGuyBar Evil Monster Saloon]] to be located.
** An unusual example is Inquiris. Little is known about the planet, save that the natives, for whatever reason, cannot make declarative or exclamatory statements. Yes, a planet who's hat is literally a specific type of sentence.

* ''Brewster Rockit: Space Guy!'' has had several. Possibly justified in the case of the Zombie Planet.

* An episode of ''X! Minus! One!'' featured a reptilian alien coming to a mining planet for one of their workers (basically a milder version of a [[TheChroniclesOfRiddick Furian]]). The reptile alien's hat is that they CanNotTellALie (although they don't have to say the whole truth either) while the "Furian's" hat is being HotBlooded. Lampshaded by the "Furian": "You know how they say we're all good at bar fights?"

[[folder: Tabletop RPG ]]

* 4th Edition ''DungeonsAndDragons'' splits the old traits of the elf race into two new races called "elves" and "eladrin". Because, you know, you can't have a single species wearing the intellectual hat and the close-to-nature hat at the same time.
** Hmmmm. Difficult to see. [[TimeyWimeyBall Always in motion is the future]].
** Hard to write down spellbooks in the middle of a forest with presumably no paper or parchment (or at least it being a rarity for nature lovers).
*** Elves all being nature lovers and living in the forest is a perfect example of this trope in and of its self.
*** They already drew a line between High Elves and Wood Elves (and also Grey Elves, Dark Elves, Wild Elves, and Aquatic Elves). They took a bunch of Cultures of Hats and turned them into Races of Hats for apparently no other reason than to fit the trope better.
** Humanity's hat in 4th edition is being driven, ambitious, TheDeterminator, and being able to learn things faster than other races because of their shorter lifespans.
* Many worlds in ''{{Warhammer 40000}}'' are characterised by this -- everyone from Cadia is a soldier, everyone from Krieg ([[GratuitousGerman German for "war"]]) is an exceptionally grim and dour soldier in a longcoat, everyone from Catachan is Rambo. To be fair, they come from a planet sitting at the gates to a NegativeSpaceWedgie from ''hell'', a (self-made) radioactive wasteland, and a [[SingleBiomePlanet Jungle]] DeathWorld full of carnivorous plants and even worse animals respectively. The hats are likely survival mechanisms.
**Well except you do see people from different worlds being different, but in a table top battle game, they are in uniform. There is actually a special character in the Catachan books that is names "Sly Marbo" an obvious lampshade of Rambo. And the Eldar have an over arching culture, but are divided into Craftworlds, each embracing a certain aspect of Eldar culture as a whole.
** Let's face it, pretty much every Imperial Guardsman is some form of cannon fodder. Except [[GauntsGhosts the ones]] [[CiaphasCain who aren't.]] And even they suffer some serious attrition. One which note, every Tanith is a ScarilyCompetentTracker, even the ones who also have other specialities. They're also all generically celtic (a mixture of Irish, Scots and Welsh influences).
** Eldar
*** Everyone from Ulthwe is a [[TheChessmaster Chessmaster]].
*** Everyone from Saim-Hann is an arrogant and aggressive barbarian on a jetbike.
*** Everyone from Alaitoc is a hooded loner with a sniper rifle.
*** Everyone from Biel-Tan is a disciplined and merciless, if highly specialized, warrior.
*** Everyone from Iyanden is dead.
** Space Marines
*** Every White Scar is a futuristic Mongol on a bike.
*** Every Blood Angel is an idealistic WhiteHairedPrettyBoy [[OurVampiresAreDifferent vampire]] with anger issues.
*** Every Ultramarine is TheMario, Roman and follows the Codex Astartes fanatically.
*** Every Imperial Fist enjoys their own pain and is an expert siege engineer.
*** Every Salamander is a ScaryBlackMan with a flamethrower, hiding a GentleGiant underneath.
*** Every Raven Guard has a jetpack and lightning claws.
*** Every Space Wolf is a certified {{Badass}} Viking with a fondess for [[BigBadassWolf wolves]].
*** Every Dark Angel is TheAtoner and sworn to secrecy about their chapter, apart from the ones who they're sworn to secrecy about, who they spend an enormous amount of time and resources hunting down...
*** Every Grey Knight is IncorruptiblePurePureness incarnate, psychic, and a religious fanatic whose faith is their chief weapon; and a daemon hunter.
*** Every Black Templar is, as [[KnightTemplar the name suggests]], a religious crusader.
*** Every Iron Hand is a cyborg {{Determinator}}.
** Chaos Space Marines
*** Every World Eater is an incarnation of AxCrazy, and/or a BloodKnight.
*** Every Emperor's Child is NightmareFuelUnleaded with a killer guitar (apart from Fabius Bile, who is a MadScientist).
*** Every Death Guard is an implacable bag of walking filth.
*** Every sentient Thousand Son is a mad wizard in power armor. The others are all ghosts.
*** Every Iron Warrior is a master siege engineer.
*** Every Night Lord is a psychotic serial killer akin to a ChaoticEvil Batman.
*** Every Alpha Legionnaire is a MagnificentBastard. They are also all [[IAmSpartacus Alpharius.]]
*** Every Word Bearer is an insane and unrelenting dark priest.
*** Every Black Legionnaire is out for revenge for the death of Horus.
* For Space Marines and Chaos Space Marines, this is largely justified due to the fact that they all share genetic material with the primarch of their chapter - essentially, they have all been deliberately modified to be the same.
** Orks
*** Every Bad Moon carries BFG's.
*** Every Blood Axe is a Kommando.
*** Every Death Skull is a looter.
*** Every Evil Sun likes to go fast.
*** Every Goff is tougher than the average Ork.
*** Every Snakebite is more primitive than any ork.
** Tau (technically not a hat for the whole culture, but every caste has a specific purpose, and you're born into your caste, with crossbreeding between castes illegal. To be fair, the ethereals are breeding the perfect warriors, builders, diplomats etc... and even though they've only had a few thousands years, they may even technically be different species by now.)
*** Every Ethereal is a ruler of some sort.
*** Every member of the Fire caste is a warrior.
*** Every member of the Earth caste is a builder.
*** Every member of the Water caste is a bureaucrat.
*** Every member of the Air caste is a pilot/navigator.

* The various alien races from ''StarControl'' come from different varieties of PlanetOfHats. The Spathi are [[DirtyCoward cowardly to the point of paranoia]], the Pkunk are hippy-dippy psychics, and there's three species each of ScaryDogmaticAliens (the Ilwrath and both breeds of Ur-Quan) and ProudWarriorRaceGuy (the Thraddash, the Shofixti, and the Yehat).
* [[LampshadeHanging Lampshaded]] in ''MassEffect''. Kaidan comments that WarriorPoet Wrex isn't exactly what he was expecting from a [[ProudWarriorRaceGuy krogan]], to which Wrex [[DeadpanSnarker dryly replies]], "Because humans are all different, but every krogan is exactly alike." Kaidan hastily shuts up.
** Wrex has a response for Garrus when ''he'' confronts Wrex with the same observation: 'I suppose it was easier to unleash a genocide virus on the krogan when you thought we were all mindless monsters, Turian.'
** According to aliens, humanity's Hat is that they're a bit of a loose cannon.
*** Also, we seem to be evolving towards a monoculture with minimal racial differences due to globalization - we just haven't gotten quite as far as the other races, yet.
*** It is, however, a fairly diverse culture as it's stated that some Turians have picked up things like Buddhism or what have you. Nevertheless, most of the 'bad guy' races tend towards this trope - the Batorians, the Geth, etc are generally all X.
*** In addition, one codex entire paraphases the current state of humanity's society. National countries and global organizations still exist and have their own independence. The Alliance is a multi-national independent entity spawned out of various national space programs and given the power to rule and be the face of humanity in space. The Alliance is, essentially, the UN in space with actual political power as far as space is concerned.
** One of the main features of Mass Effect was that although each race ''has'' a hat, the hats also tend to come off a lot.
*{{Meteos}}, despite being a puzzle game, has a good number of these. There's a planet for robots, insomniacs, stubborn miners, shapeshifters, timid jumpers, gangsters, telepaths, bees, ninjas, and ascended psychics each.
* The computer game ''[[http://en.wikipedia.org/wiki/Spaceward_Ho! Spaceward Ho!]]'' gets a honorable mention. It's a light turn-based strategy affair and doesn't have culture, but planet ownership is indicated by hats. A variety of cowboy hats worn by the actual planets. Santa hats if the game is played on December 25th.
* In {{Spore}}, when your race reaches the Space phase, they are assigned a hat based on their actions up until that point, which usually falls into the standard sci-fi racial norms.
** This actually makes a bit of sense: until space-travel, members of a race would have to fill all the economic niches necessary for survival; once there's easy star-travel, specialisation would be possible. See: finding a cheap toy made in the U.S., post-{globalism and Chinese capitalism}.
* Earth has become this in MegamanStarForce, with the hat being ThePowerOfFriendship. People even get significant discounts and increased political rights as they become popular.
* In ''{{Startopia}}'', the alien races are each suited to one specific task -- OK, two related tasks for the blue-collar Salthogs. Karmarama are purple four-armed hippes, they plant seeds. Turraken are two-headed nerds, they're all scientists. Sirens are sexy winged humanoids, and the only aliens in the game with obvious gender dimorphism, and they "love" others. And so on. The most specialised are the Grekka Targ, who are solely employed to run your communications gear.
* In ''Chronomaster,'' you play a retired ''designer'' of [[PlanetOfHats Planets of Hats]]. The mini-universes you end up visiting include a hypermilitant world, a space casino, and a {{Cloudcuckooland}}. To top it off, one world that you never even see is implied to be pop Jung-themed, and solving an optional puzzle requires you to [[GenreSavvy warn somebody who's going there of the inevitable]] [[ShadowArchetype Evil Twin threat.]]
* ''Lego Star Wars'' lampshades the Planet of Hats, by using actual hats. There are machines around the various levels that will stamp a Storm Trooper helmet on your head. It does not fit on Chewbacca's head, and rests at a jaunty angle. No matter who is wearing the helmet, and how badly it fits, or what else the characters are wearing, Stormtroopers will not fire on them, and they can access Stormtrooper only areas.
**Unfortunately, Leia will refuse to wear the Stormtrooper helmets, so real troopers will target ''her'', and if Luke/Han/Chewy accidently takes crossfire, they lose ''their'' helmets and [[PaperThinDisguise the gig is up]].
**Won't shoot until you start shooting at them, anyway. Then you have to go back half the level and get a new helmet to access the next area.
* The world of ''{{Loom}}'' is divided into xenophobic guilds, each with a specific craft, e.g. Weavers, Glassmakers, etc. Each guild's citizens seem to all bear the characteristics of their guild. For instance, the glassmakers value traits such as clarity and beauty, and have names like [[PunnyName Luscent Bottleblower]]. Somewhat justified in that the thing that defines them is what their community was formed on in the first place.
* {{Touhou}} takes this trope litterally, because 99% of the characters wear hats. One can also talk about the Planet of Badass Lolitas.

[[/folder]]

[[folder: Web Animation ]]

* Parodied in the Flash series ''[[http://www.newgrounds.com/collection/burntfaceman.html Burnt Face Man]]''. In the conclusion of episode 7, Bastard Man (yes, that's his name) [[{{Spaceballs}} steals all the world's air with a vacuum cleaner]] (yes, he did that) and tries to sell it to a "planet of shifty characters". Everyone on the planet is wearing a large overcoat and hat or they are hidden in the shadows, the main shifty guy telling Bastard Man that they might not pay him for the air because they're all "a bit shifty".
** I'm guessing that's Flash the computer program, not the comic book character?

[[folder: Web Comics ]]

* ''[[http://www.melonpool.com Melonpool]]'''s planet Melotia is a planet of couch potatoes. There's a BizarreAlienBiology explanation, with their antennae resonating to Earth television broadcast frequencies.
* In ''SluggyFreelance'' the residents of the Dimension of Lame are all incredibly sweet, nice, rice cake-loving pacifists. The most deranged psychopath among them suffers an incredible bout of guilt after slightly bruising the toe of a murderous demon. Even the rules of the universe conform to this Hat: the sewers smell like flowers, fermentation doesn't exist, and all swear words are automatically replaced with a "bleep" noise.
* ''[[http://www.goats.com Goats]]'''s Multiverse has entire Dimensions of Hats, such as Topeka Prime, the farm dimension, complete with [[http://www.goats.com/archive/060322.html cow computers]]. Each dimension, however, has a pub.
*''[[http://www.komikwerks.com/episodes.php?x=32&y=13&ti=49&utype=AOL&ep=463 This strip]]'' directly discusses this trope.
* ''{{Curvy}}'' [[InvokedTrope invokes]] this; every Earth explicitly has a gimmick, and ours is apparently "Boring World".
* Parodied in [[http://mountaincomics.com/?p=49 this]] episode of Mountain Time, as the astronauts are all too eager to attach a gimmicky label to a newfound planet.
* Some of the aliens seen in BuckGodot seem to fit this trope, with all individuals seen having similar behaviour or jobs. However, just as many are as varied as humans both in behaviour and appearance.
* Subverted in ''Quentyn Quinn, Space Ranger!'' Groonch the Gnorch, a parody of Worf from ''StarTrek'', says that despite being raised with the ideals of another alien race, he strives to be the kind of noble warrior honored by "the Gnorch peoples." Quentyn asks, "Which peoples?" Groonch then learns, to his complete surprise, that the Gnorch species is rather culturally diverse and only a handful of ancient tribes were as warlike as he thought. His own outfit is an odd cultural mishmash.

[[folder: Web Original ]]

*[[LimyaaelsFantasyRants Limyaael]] discusses this in her ''Avoiding gimmick-worlds'' rant [[http://limyaael.livejournal.com/524485.html here]].
* ''AssociatedSpace'' has Sarmatia, the planet of SpaceAmish nomadic horse warriors, and New Tau Ceti, the planet of religious fanatic sheep-men.
* Played straight in some of the more comedic episodes of ''AHDotComTheSeries'', when (much like ''StarTrek'') this week's timeline is simply a planet-sized TownWithADarkSecret. More usually averted, as after all all the planets featured are variants of Earth and often feature several power blocs facing off.

[[folder: Western Animation ]]

* The reverse of this is used in the ''SouthPark'' episode "Cancelled", when it is revealed that Earth was created with disparate groups specifically for the creation of conflict to provide entertainment as a reality TV show.
* ''{{Futurama}}'' would often use ridiculous examples, i.e. the Neutral planet, the cannibal planet, planet of human-hating robots. In "Love and Rocket", Dr. Zoidberg talks about the planets destroyed by [[ItMakesSenseInContext love radiation]] why not, "including two gangster planets and a cowboy world."
** Also, taken more literally, in one episode Fry travels to the edge of the universe and uses the coin-operated binoculars to look to the other side. He sees the exact same people as he's with, including himself, but they're all wearing cowboy hats.
*** ''Severely'' lampshaded when Fry comments that there must be tons of different universes that are all slightly different. The Professor responds, no, there's just the two: regular universe and cowboy universe.
** Later, other parallel universes are created, each with its own distinctive quirk-- a world of hippies, Romans, bobbleheads, robots, etc.
** The opening of a certain episode sees the Planet Express crew return pantless and low on supplies from "the planet of the moochers".
* ''{{Transformers}}: Cybertron'' is very guilty of this. There are three planets where a great deal of the action takes place: Gigantion, the giant planet, is populated by massive Transformers obsessed with construction, aided by the tiny Mini-Cons. On Velocitron, the speed planet, the fastest rule and those who don't measure up are left in the dust. And on the unnamed Jungle Planet, might doesn't ''make'' right so much as it ''is'' right. As if Cybertron, a planet populated by giant transforming robots, wasn't enough of a hat planet in its own right. (Admittedly, "giant transforming robot" is a pretty cool hat.)
** As well, ''{{Transformers}}: TheMovie'' had the planet Junk, where a race of robots made of scrap live; their entire culture is based on [[AliensStealCable TV and radio transmissions from Earth]], with the result that they say things like "Stop, thief! No welcome wagon 'hello stranger' with that new coffee flavor for you!". This was homaged in the LiveActionAdaptation where Optimus Prime claimed the Autobots learned to speak English 'from your Internet'.
*** Well, not so much a planet as a giant space garbage clump. Same basica idea.
** Pretty much every non-Transformer alien planet in ''TransformersGenerationOne'' was made of hat.
** Likewise, ''TransformersHeadmasters'' had a planet of humans innately in touch with nature, and a pirate planet.
* Averted in ''TransformersAnimated'', where the robots have wildly different cultures, preferences, and interests. And their politics are just as messed up as ours.
* One episode of ''VeggieTales'' had two feuding Towns of Hats used for their Good Samaritan retelling. One town wore shoes and boots on their heads, and the other wore pots. The purpose was to show how people are divided by trivial differences, a rare acknowledgment of the silliness of Planets of Hats.
* A three-part ''PinkyAndTheBrain'' episode involves the protagonists being taken to a city of hats. There, everyone is ... a hat.
* ''InvaderZim'' parodies this; the Irken Empire includes such ridiculous examples as "Conventia, the Convention Hall Planet" and "Foodcourtia," a planet of nothing but restaraunts. Justified because these planets don't seem to actually start out this way: one episode shows the Tallests after the conquest of Blorch, deciding to make it a "parking garage planet" ''literally'' on the spot.
** Another example might be the Planet Jackers, whose culture seems to revolve around collecting new planets to throw into their sun.
** Fans seem to assume the Vortians were essentially a species of nothing but scientists. This is never made explicit on the show, but it ''is'' plausible, given that their alliance with the Irkens seemed to consist largely of building weapons (and that the only two important Vortian characters, Lard Nar and Prisoner 777, were both inventors).
* In ''{{Megas XLR}}'', Jamie mentions to Kiva to take them to the "planet of the Space Amazons", to which Kiva replies "I'm from the future, not a comic book!". Though the post credits sequence seems to suggest such a planet exists...
* The titular anthropomorphic ducks of ''TheMightyDucks'' cartoon come from a planet whose entire culture revolves around hockey. Yes, seriously.
* Most episodes of the ''SuperMarioBrosSuperShow'' featured Mario, Luigi, Toad and Princess Peach travelling to a different world built around a particular theme (e.g., karate, rock-n-roll, cowboys, rap). Also, Bowser and his minions always seemed to conform to the "hat" of the world, appearing as a different stock villain in each episode.
* ''EarthwormJim'' had that one planet inhabited by people that are easily startled.
-->'''People:''' AAARGH! Something green! AAARGH! Something not green!
-->'''[=PsyCrow=]:''' I love this planet.
* {{Darkwing Duck}} had some fun with this trope in one episode, where our hero visits the planet Mertz, where every single person is a superhero (complete with everyone having a totally unnecessary secret identity.) There is only one person on the planet without super powers, whose name is actually [[{{exactlywhatitsaysonthetin}} Ordinary Guy.]] Everyone else spends their entire lives trying to rescue him from peril (which in practice means gigantic, city-smashing brawls over who gets to help him cross the street.) Needless to say, Ordinary Guy's life sucks. Eventually, he snaps and becomes the planet's first and only supervillain. This gives him an outlet for his rage, and gives the heroes some actual evil to fight, making everyone much happier.
* Subverted in a meta sense by AvatarTheLastAirbender. All the characters are Asians and Inuit (or at least, [[FantasyCounterpartCulture Fantasy Counterpart Cultures]] thereof), but everyone's different in their own way - you got the [[ProudWarriorRaceGuy Fire Nation and Water Tribe]] (the former of which is also TheEmpire), [[AmazonBrigade Kyoshi Warriors]], OldMentor, LaResistance, etc. Pity about the live-action film, which, by assigning a different real-world race to each nation, goes back to giving each race a hat...
[[/folder]]

[[folder: Real Life ]]

* This is arguably a reflection of TruthInTelevision (if you can work that out) as most cultures on Earth, as viewed by other cultures are often viewed in only a couple of simple terms as it's too difficult to view every other culture in its entirety.
** Case in point: Arabs as terrorists, Africans as hut-dwelling aboriginals, Australians as Crocodile Dundee, Americans as rednecks and/or rich snobs, French as cowards, et cetera.
**** I'd think the french as cowards is an American view; most others view them as arrogant. I blame de Gaulle.
**** No, no. Not just American's, the English and I think most of the world think it too. Also, you forgot smelly.
*** Crocodile Dundee or Steve Irwin for Australians. (though as for Irwin himself, well, RIP, he is still missed by many.)
*** There's not a great deal of difference between those two.
** Dear God, just ''look'' at the sheer size of the HollywoodAtlas page...
* Oddly, a RealLife example in the town of Hay-on-Wye in Wales, a town that is essentially a huge bookshop.
* And Louvain-la-Neuve, in Belgium, is a town totally build around college studies. There are only universities, students, and all kinds of facilities for students. You move in when you enter university, you move away when you graduate.
** The college town phenomenon is also common in the United States.
* Not directly related to, but played with in atheist blogger Prof. P. Z. Myers' [[http://scienceblogs.com/pharyngula/2006/01/planet_of_the_hats.php "Planet of the Hats"]] post.
* To an extent this is also present in many small towns the world over, where the town was founded for a particular industry (e.g. coal mining, gold mining, oil, etc) where virtually every one works, in one form or another, for the town's main industry.
* Jupiter's Galilean moons count as examples of this trope. Each one, aside from having its own (albeit EXTREMELY tenuous) atmosphere, is unilaterally unique in some aspect--Io is vulcanism incarnate, Europa is covered in ice and has an ocean beneath it, Callisto is basically a black cueball of craters with impact basins taking up a good portion of its surface, and Ganymede is almost a literal planet--it's bigger than Mercury and it even has its own magnetosphere.
