!!Species debuting in ''The Original Series''

-->''"We don't know what to do about Humans. Of all the species we've made contact with, [[HumansAreSpecial yours is the only one we can't define]]. You have the arrogance of Andorians, the stubborn pride of Tellarites. One moment, you're as driven by your emotions as Klingons, and the next, you confound us by suddenly embracing logic."''

Also known as Terrans, humans are a founding member of the United Federation of Planets and the backbone of Starfleet. Following a century of internal warfare and strife, Earth became warp-capable on April 5th, 2063 and caught the attention of other Alpha Quadrant races, who had previously dismissed it as an InsignificantLittleBluePlanet. All in all, humans are pretty cool.

* TheAssimilator / BenevolentAlienInvasion: In-universe, the Federation is often [[AlternateCharacterInterpretation accused of this]] by detractors, being a "[[HumansAreSuperior Homo-Sapiens Only Club]]" that masquerades as an inter-species alliance and who makes [[DefeatMeansFriendship peace with enemies]], simply to get them to take their "[[AssimilationPlot rightful place]]" in the Federation council.
--> '''Eddington''': You know, in some ways you're even worse than the Borg. At least they tell you about their plans for assimilation. You're more insidious. You assimilate people and ''they don't even know it''.
* BewareTheNiceOnes: Quark had some choice words to say about hew-mons in [[WarIsHell wartime]], suggesting that if you take away their creature comforts, fancy technology and put them through the wringer, they've got the potential to be even more frightening than ''Klingons''.
* BoldlyComing: It seems that a lot of Federation citizens are fans of [[PleasurePlanet Risa]].
* CloakAndDagger: There exists an obscure provision in the Federation Charter, Section 31, which allows for this kind of activity.
* DrinkOrder: Root Beer apparently is very popular, even in alien bars. Non-alcholic "Synthehol" is also frequently served on Federation starships.
* GoodIsNotSoft: Despite being physically weaker than Vulcan, Romulans, Klingons, and a variety of other alien species, they can be a force to fight when push comes to shove.
* HeadInTheSandManagement: The Federation can't intervene in the fate of non-member states, and will often step on weaker worlds in the interest of politics. To avoid breaking their treaty with Cardassia and starting another war, the Federation forcibly evacuated settlers in the (Cardassian-owned) Badlands, giving rise to the Maquis terrorists.
* HumansAdvanceSwiftly: Lampshaded in ''Enterprise'', where Vulcan Ambassador Soval freely admits that the reason they've been trying to keep them back is because humans are advancing so fast, they are literally scaring the crap out of a race that actively suppresses their emotions. Q echoes the same concerns in the first season of TNG.
* HumansAreDiplomats: One of the founding four races who established the Federation, alongside the coldly logical Vulcans, the emotional Andorians, and the stubborn Tellarites. In addition, the first Federation President, Jonathan Archer, was a human.
** Made more impressive since these species had been traditionally at each other's throats for ''hundreds'' of years, ''especially'' in the case of the Vulcans and Andorians. Humanity managed to make earn enough points with each species to unite them into a loose Coalition of Planets by 2155, leading to the Federation officially being founded six years later.
* MarySueTopia: Discussed in ''Series/StarTrekDeepSpaceNine'', where it's revealed that some races consider the Federation to be one. Quark and Garak have some fun comparing it to Root Beer, apparently the favourite DrinkOrder of people from Earth.
-->*''Quark offers some root beer to Garak, who tries it and gags''*\\
'''Garak''': It's ''vile!''\\
'''Quark''': I know. It's so bubbly and cloying... and happy.\\
'''Garak''': *''Greatly amused''* Just like the Federation?\\
'''Quark''': And you know what's really terrifying? If you drink enough of it, you begin to ''like'' it.\\
'''Garak''': It's ''insidious!''\\
'''Quark''': ''[[MeaningfulEcho Just like the Federation]]''...
* MonumentalView: Starfleet Academy enjoys a view of the Golden Gate Bridge, which unfortunately would place it in the middle of a mountain range. ''Voyager'' retconned this somewhat with a establishing shot of Starfleet H.Q., which is built into the mountains on stilts.
* MostWritersAreHuman: Which is why all ''Franchise/StarTrek'' series to date have centered around a human captain.
* NoPoverty: A central part of the setting, humanity solved this problem after meeting the Vulcans.
* NoSuchAgency: Section 31? Never heard of it.
* NoTranshumanismAllowed: Transhumanism was considered the new frontier of science and humanity's great hope, until Khan Noonien Singh and similar warlords cropped up. Following a ghastly Eugenics War which enveloped the whole world in chaos, genetic engineering was outlawed, and mankind turned to the stars to find a slower path toward evolution. These days, genetic engineers find work on the [[BackAlleyDoctor black market]], performing augmentation on mentally-disabled or otherwise challenged children. While Dr. Bashir turned out fairly normal (although he had to hide the truth from Starfleet Academy), "Statistical Probabilities" showed us three individuals who could have lived perfectly productive-if-simple lives had their parents not tried to play God. The result? Social maladjustment, sadistic behavior and a life behind bars (or [[BedlamHouse as good as]]).
* PlanetOfHats: Averted; we're the only planet that doesn't have a hat. Unless you count Ron D. Moore's "[[ThePollyanna Starfleet walk]]."
** Several characters have commented on how relatively fast humanity expanded compared to other species and how quickly humans tend to pick up a skill or job. Humanity's hat seems to be taking everything UpToEleven. It's stated to be the reason why Vulcans held back humanity for so long; the fact that the same individual could be at one moment as emotional and bloodthirsty as a Klingon, and the next able to logically reason with a Vulcan, made the Vulcans outright ''scared''. Their adaptability to any given situation is exceeded only by the Borg.
** Society is clearly moving in that direction though; nearly every time Star Trek humans end up in modern or near-modern America the amount of cultural diversity freaks them out.
** This actually comes up subtly in several ExpandedUniverse novels. Scenes taking place during the ''Enterprise'' era tend to explicitly mention different human characters' nationalities in the narration more than scenes set later in the future. This isn't as noticeable in the ''Enterprise'' novels themselves, but the flashbacks to that era in ''StarTrekDestiny'' are rather jarring when compared to the 24th century scenes.
* PlanetTerra: Used a few times (the Mirror Universe has the Terran empire; the original series occasionally contrasts "Terrans" with "Vulcans").
* PunyEarthlings: We're generally portrayed as weaker, less intelligent, and shorter-lived than other major species in the Alpha Quadrant. Vulans and Romulans, in particular, are downright patronizing in their dealings with humans, whom they regard as dim children.
* RenegadeSplinterFaction: The Maquis, consisting of Earth colonists who objected to losing their planets to the Cardassians after a treaty redefined the border after the war. Eventually wiped out by the Jem'Hadar when the Dominion allied with the Cardassians.
** Terra Prime in the 22nd Century, a Xenophobic group that objected to alien nationals being on Earth and experienced a massive surge in popularity after the Xindi Incident.
** Section 31, a rogue Black Ops group within Starfleet, dedicated to keeping Earth a paradise ''[[UtopiaJustifiesTheMeans by any means]]''.
* ScienceHero: Since the Federation mines research from throughout the Alpha Quadrant, and they haven't despoiled their territories like the Romulan or Cardassian empires, by the 24th century their tech is considered some of the mightiest in the galaxy.
* TookALevelInBadass: Even with the Vulcans supposedly delaying their warp program, Humanity still managed to go from being survivors of a nuclear war, to one of the founders of an [[TheFederation interstellar alliance]] in just under a century. The latter only ten years after the launch of their first Warp 5 vessel, which brought them properly into the interstellar community.
* WeAllLiveInAmerica: Or at least the West. All the names are surname-last, alien cultures that were inspired by other Earth cultures are seen as mind-blowing, and the French all sound like grumpy Englishmen.
* WeWillSpendCreditsInTheFuture: Averted as the Federation has abandoned money-based economics, at least within it's own borders. There apparently is some form of currency used when trading with other races outside the Federation.
** Parodied in the [=DS9=] episode "In The Cards", where Jake actually can't give Nog a justifiable reason ''why'' they don't use money anymore, aside from abandoning it when they adopted their philosophy of "working to better ourselves and the rest of humanity".
--> '''Nog''': What does that even mean?\\
'''Jake''': It means... *''{{Beat}}''* ... it means, [[MathematiciansAnswer we don't need money!]]


-->''"Live long and prosper."''

The original SpaceElves, and Trek's most iconic alien race, famous for their strict adherence to logic and reason. They were the first extraterrestrial species to make First Contact with Humans. They offered huge assistance to a devastated post-World War III Earth, enabling the elimination of world poverty, disease and crime. Nevertheless, many humans still cannot bear their {{pointy ears}}; their arrogance; their freezer-temperature sex drives (Vulcans get freaky approximately once every seven years). Vulcans appear in all six Trek series, four of which feature a Vulcan or a half-Vulcan as a crewmember.

* ArrangedMarriage: Vulcan marriages are determined at birth. If, for whatever reason, the female does not want to go through with the marriage, then the ceremony of koon-ut-kal-if-fee ("marriage or challenge") is invoked: The male fights for the right to keep his mate against a challenger of her choosing. This is a DuelToTheDeath.
*** It should be noted that a female Vulcan can protest if she wants (hell, even fight the duel herself).
** PerfectlyArrangedMarriage: They do break off the marriage if it isn't this as well.
* TheAtoner: They were once a ProudWarriorRace that was probably even fiercer then Klingons or [[HumansAreWarriors humans]]. Horror at the results of this made them turn to the teachings of Surak and follow the rather painful creed of the time of the show to control their violent emotions.
** And Romulans are Vulcans who ''did not'' follow Surak. Nuff said.
* BizarreAlienBiology: Vulcans possess an inner eyelid, or membrane, which protects their vision from bright lights. Spock dismissed it as a redundant organ, like our appendix.
** In addition, their hearts are located on the right side of the torso, in between the ribs and pelvis.
--->'''Dr. [=McCoy=]''': He's lucky that his heart is where his liver should be, or he'd be dead!
* DuelToTheDeath: Oddly all duels we have seen never resulted in a death, guess they didn't feel like changing the name.
* GoodIsImpotent: Averted. The Romulans, having embraced war and avarice, also lost the ability to pull off mind melds or nerve pinches. Meanwhile, the Vulcans continue to try to reconcile with their Romulan kin.
* FeelNoPain
* HatesBeingTouched: Justified due to their telepathic abilities. And since the palm is the focal point of mind melds, it's rare for a Vulcan to even shake your hand.
* IComeInPeace: The Vulcan salute.
* InsufferableGenius: Do not argue with a Vulcan. You will lose.
* KungFuJesus: Vulcan's answer to Jesus and Moses, a wise man named Surak, saved the species by devising a new philosophy based on logic. Surak concluded that the root of the problems on Vulcan lay in the uncontrolled outpouring of its peoples' emotions. Although this new ideology spread rapidly across Vulcan, a minority known as "those who march beneath the Raptor's wings" rejected Surak's message. A destructive war began including the use of atomic bombs and among the victims was Surak himself.
* {{Kuudere}}: A solid Type 2. Just because they're governed by logic doesn't mean they are a hive mind. A Vulcan can 'reason' themselves all the way into, for example, committing treason (''Star Trek VI'') or running guns for Maquis settlers (''[=DS9=]:'' "The Maquis"), if it seems logical to do so.
-->'''Gul Dukat:''' You believe her? Why? Because Vulcans don't ''lie?''\\
'''Sisko:''' As a rule, they don't.\\
'''Gul Dukat:''' They don't [[BewareTheQuietOnes blow up ships either]], "as a rule."
** To the extent that a Vulcan can be driven [[SanitySlippage utterly insane]] by the [[WarIsHell horrors of war]], become a deranged serial killer, yet ''never once'' give up the sincere belief that what they are doing is complete and utterly ''logical'' (''[=DS9=]'': "Field of Fire").
* LivingMemory: Some Vulcans can "cheat death" by implanting their ''katra'' -- essentially their memory -- into another person via mind-meld (''"Rememberrrr..."''). Dr. Bashir in the episode "The Passenger" explains this away as "[[MaybeMagicMaybeMundane synaptic pattern displacement]]."
* MateOrDie: Every seven years, Vulcan males and females experience an overpowering mating drive known as ''pon farr'', often focused on a single object of desire (or a holographic facsimile thereof). Once triggered, Vulcans must have sexual contact with ''someone'', or else face insanity and death.
** If a mate is not available, there are other ways to relieve the effects of the ''pon farr''. The first is meditation; The second is violence. This is seen in the Voyager episode "Blood Fever", when B'Elanna Torres and Ensign Vorik fight in the traditional Vulcan manner. The violence ends the pon farr. The other option is extreme shock; in the TOS episode "Amok Time", Spock believed he had killed James T. Kirk, his "best friend", thus providing sufficient shock to nullify the effects of pon farr.
* MemeticHandGesture / StrangeSalute: The Vulcan salute, meaning "Live long and prosper." Nimoy based it on a Jewish blessing representing the Hebrew letter Shin (ש).
* NeatFreak: Vulcans do not like to touch their food with their hands, preferring to use utensils whenever possible. Even if it's a breadstick.
* NervesOfSteel: According to [=McCoy=], Spock (and presumably all Vulcans) have almost no blood pressure. With an average body temperature of 91°F, they don't even need to ''sweat''. ("That green ice water you call blood!")
* NoSenseOfHumor: Vulcans are renown for this, though many of them are [[DeadpanSnarker Deadpan Snarkers]] instead.
** They would arguably be the most deadpan of snarkers, ever.
* OmnidisciplinaryScientist
* TheParalyzer: Vulcan Nerve Pinch. This is not a canonical name for the attack, but the writers on ''VOY'' finally caved and had Tom refer to it by that name.
** This move is not, in fact, exclusive to Vulcans only; at least one non-Vulcan character per show has mastered it, usually the replacement Spock (Data, Odo, Seven of Nine). Picard also acquired the ability after mind-melding with Sarek.
* PassionIsEvil: For Vulcans, anyway. They need to keep their emotions in check, or else they turn into raving lunatics.
* ProudScholarRaceGuy: A Vulcan's idea of a wild night is thirteen hours of meditation followed by a seaweed TV dinner.
* PsychicLink: Mind Meld.
* Really700YearsOld: There are instances of them living over two hundred and twenty years. Spock is over hundred and fifty when he goes back in time and ends up trapped in an [[Film/StarTrek Alternate Reality]] TOS-Era.
* ScrewYouElves: The only loveable Vulcans in ''Star Trek'' are the ones already affiliated with Starfleet or other organizations within the Federation. Native Vulcans tend to be speciesist and rather brusk in their relations with other Alpha Quadrant races, barely masking their low regard for the illogical aliens they must begrudgingly work with. They also discriminate against those who marry outside of the race.
** In the prequel series ''Enterprise'', the Vulcans were retconned into quasi-antagonists, including [[TheCoup a militaristic sect]] which was colluding with Romulus.
* TheSpock: [[TropeNamer Trope Namers]], [[TropeMaker makers]], and [[TropeCodifier codifiers]].
* SpockSpeak: Vulcans speak in a low, dull monotone and generally avoid using contractions.
* TheStoic
* SuperStrength: Vulcans are about three times as strong as an average human, owing to Vulcan's higher gravity -- though a phaser blast will take one out easily.
* TheTeetotaler: For obvious reasons, Vulcans are said not to drink alcohol. Though they are depicted indulging for ceremonial rituals or when the storyline warrants. In the Star Trek: Voyager episode "Repression", Humans and Vulcans are shown drinking a Vulcan alcoholic drink called "Vulcan Brandy". A Vulcan's constitution is probably immune to our comparatively weak alcohol.
* UnusualEars: The distinct PointyEars of Vulcans are often lampshaded by bob-earred humans.
-->'''Soval:''' What is their fixation with our ears?
-->'''T'Pol:''' I believe they are envious.
* {{Veganopia}}: Of course, there are plants, and then there are ''Vulcan'' plants. In a ''Star Trek'' novel set on Spock's homeworld, the characters are attacked by [[ManEatingPlant a mobile, shrieking, carnivorous plant]] native to the region ... and after it's been phasered to death, Spock eats some of it.
** One of the early TOS novels postulated that Vulcans were vegetarians partly because the herbivores previously used as meat died off during Surak's time.
** The most common reason given for their vegetarianism is the same one that led them to pacifism. They are such a violent and destructive race that they have to go to extreme lengths to not destroy themselves/conquer the universe/destroy the universe. This includes eating spinach, rather than sating their bloodlust with meat.
** However, it's mentioned that the Rite of Ta'loth involves young Vulcans being sent into the desert armed only with a ritual blade, implying that when push comes to shove, they ''will'' meat in order to survive. Unless these deserts are commonly populated with aforementioned ManEatingPlant, of course.
* WillNotTellALie: Vulcans, allegedly - something of an InformedAttribute.
-->'''Saavik:''' ''([[FascinatingEyebrow raises eyebrow]])'' You lied.\\
'''Spock:''' I [[NoExceptYes exaggerated]].
** Vulcans don't lie in the same way [[MetaphoricallyTrue Jedi]] don't lie.

-->''"Today is a good day to die!"''

Huge, bumpy-headed SpacePirates with unlimited strength, and very little in the way of patience. Originally a recurring villain for Kirk's ''Enterprise'', they became wildly popular and have since appeared in all four live-action spinoffs, along with [[TheUsualAdversaries obligatory appearances]] in most of the films. Though technically an ally of the United Federation of Planets, Klingons [[LeeroyJenkins aren't entirely housebroken]], and are always itching to make war with ''some''body. Protip: If you're a bartender, it's unwise to try [[IllTellYouWhenIveHadEnough cutting off]] a Klingon's drink.

* AlwaysChaoticEvil: Klingons are generally portrayed this way in the [[Series/StarTrekTheOriginalSeries original series]], but not in the others.
* ArmorPiercingSlap: Klingon divorce proceedings. Followed by a SpitefulSpit.
** Alternatively, in ''[[Film/StarTrekGenerations Generations]]:''
-->'''Lursa:''' You had ''better'' be initiating a mating ritual.
** If you strike another male Klingon with the back of your hand, it will be interpreted as a challenge to the death. Better to use your fist.
* AsskickingEqualsAuthority: See "Klingon Promotion", below. In addition, political candidates seeking to be elected Chancellor must first duel each other to the death. (Well, that's one way of making the election cycle exciting.) This weeds out any chickenhawks from the election pool; the Chancellor can't blithely declare war without prior field and hand-to-hand combat experience.
* BadassBandolier: Gold in TOS, chainmail in TNG. And they're ''baldrics'', not bandoliers.
* BattleCouple: Klingon {{Mythopoeia}} is about the first two Klingons pillaging the heavens. Later legends tell of Kahless and Lady Lucera. And Klingon couples are often found fighting side by side.
* BigBadassBirdOfPrey: The iconic Klingon Bird-of-Prey. A fearsome warship in its day, this model was eventually outclassed in the [=24th=] century by the Federation and the Romulans. It is still capable of taking on many times it's number of Dominion and Cardassian ships.
* BizarreAlienBiology: Klingons are loaded with redundant organs.
* BrawnHilda: As shown above, even the most refined Klingon women are still very hairy (particularly their eyebrows).
* CharacterizationMarchesOn:: The original series had the Klingons as being mostly warlike with few redeeming traits. GeneRoddenberry didn't like them being the "Black Hats" of the saga so in ''[[Series/StarTrekTheNextGeneration The Next Generation]]'' he made a Klingon a regular cast member and established the "honor" aspect to their society.
* CleavageWindow: Female Klingon uniforms.
* CulturedBadass: Klingons are passionate opera lovers.
* DeathOfTheOldGods: According to their legends, Klingons ''slew their own gods''.
-->'''Worf:''' They were more trouble than they were worth.
* DemocracyIsBad: The Klingons' brief foray into representative government is treated by their historians as a kind of Dark Age.
-->'''Dax:''' ...''but'', it's interesting to note that this first and only experiment in Klingon democracy actually produced several reforms that--\\
'''Sirella:''' You are [[WagTheDirector STRAYING FROM THE SAGA!!]]
* DidYouJustPunchOutCthulhu: The mythological first Klingon BattleCouple sacked the heavens. They read the story at weddings. That's what Klingons consider romantic.
* DrunkenMaster: "Even half drunk, Klingons are among the best warriors in the galaxy."
** TheDrunkenSailor: And even the greatest of Klingon heroes are not allowed to receive their honors until they have proven that they can hold extreme amounts of Blood Wine.
* EnemyMine: Their own riff on the book of Genesis had the first Klingons, Kortar and his mate, dueling to the death with bat'leths. Kortar's adversary had him at swordpoint, but chose to spare him because, "If we join together, no force can stop us." And thus the Gods speaketh, "OhCrap".
* EvenEvilHasStandards: Klingons and Romulans once shared an alliance for a number of years. Big mistake. Over the years, a number of disasters - including the Khitomer Massacre, the result of failed encroachments on Klingon colonies - led the Klingons to develop a deep-seated hatred for the Romulans. The Romulans are probably the species that Klingon society in general despises most of all. (TOS: "The Enterprise Incident"; TNG: "The Neutral Zone")
-->'''Worf''': "They have no honor! They consider Klingons and humans to be a waste of skin!"
** Worf once angrily berated Alexander for being a school bully on The Enterprise D, as it is the ''lowest'' form of dishonor for a warrior to bully those weaker than he is.
* EvilIsHammy: Veteran Klingon Robert O'Reilly told all neophyte Klingons that the most important part was to say their lines with utmost belief, and "[[ChewingTheScenery go all the way.]]" ''Qapla'!!''
* FallenAngel / TheFerryman: Klingons who die without honor aren't allowed into Valhalla (or "Sto-vo-kor"), but are instead sentenced to Gre'thor, their version of Hell. The Barge of the Dead is the mythological ship to Gre'thor, captained by Kortar, the very first Klingon. When Kortar became more powerful than the gods who created him, he destroyed them, and, as punishment, he was condemned to ferry the souls of the dishonored for all eternity. (VOY: "Barge of the Dead")
* TheFarmerAndTheViper: Ironically for an honor-minded society, Klingons find excuses to kill each other and steal their land, or betray their Federation allies. It's less to do with greed than the Klingon propensity for violence: Chancellors are constantly [[PretextForWar directing hostilities outward]], rather than face civil war at home.
* FeudalFuture: The culture of the Klingons is a hodgepodge of western stereotypes of the samurai, the Zulu, the Vikings, and various Native American nations — a proud, warlike and principled race. Klingon society is based on a feudal system organized around traditional Great Houses of noble lineage, to which various parts of the population owed fealty. The Great Houses are represented in the Klingon High Council, which is led by a Chancellor. Unusual for ''Trek'', Klingon women aren't treated as equals (except as soldiers in the field). They are prohibited from serving in the High Council and can't inherit control of their Houses unless they have enough money -- and no male successors. On other hand, women have a tremendous degree of clout regarding what goes on ''within'' the Houses. (This was Ron D. Moore's concession in [=DS9=], as he felt there was next-to-zero Klingon women being represented in the series.)
* {{Flanderization}}: Originally depicted in ''The Original Series'' as calculating {{Warrior Poet}}s akin to Samurai. Later became Vikings InSpace.
** Lampshaded in ''Enterprise'', where 22nd Century Klingon doctors and lawyers comment that they're finding themselves increasingly under the thumb of the Warrior Caste. By the 24th Century, the Warriors are all that's left.
* GodEmperor: The Klingon treatment of Kahless the Unforgettable.
* GlorySeeker
* HandWave: The Klingons' varying appearance used to be the single most popular piece of fanwank among Trekkies.The real reason for the discrepancy between TOS Klingons and their feature film and later television series counterparts was a lack of budget. Kang, Koloth, and Kor each gained a ridged forehead when they reappeared on [=DS9=]. Worf acknowledged the continuity holes when the crew of [=DS9=] visited Kirk's ''Enterprise'' in the episode "Trials and Tribble-ations," but offered no explanation, saying merely, "We do not discuss it with outsiders."
** A canonical reason was given for the change on ''Star Trek: Enterprise'', revealing that it was caused by a failed attempt to create Klingon [[SuperSoldier Augments]], due to their fear that Starfleet were creating super soldiers after encountering some relics from the Eugenics War. Due to one of the test subjects having an alien form of flu, it mutated into an airborne plague that swept across the Empire, killing many until it was finally cured, but causing them to lose their ridges as a side-effect.
* InformedAbility: Arguably, their status as mighty warriors, seeing as they're routinely defeated in hand to hand combat by Humans, who are supposedly several times weaker than Klingons and have no redundant organs. This is particularly noticeable in the DS9 season 4 opener "The Way of the Warrior"
* JabbaTableManners: The Klingons of the ''Star Trek'' universe universally gulp and slurp down food like slobs. In their case, it is to show how tough and free of pretentious "good manners" and straightforward and honest their society is, not to show how "evil" they are.
** Inverted in a TNG episode, when Riker joined a Bird of Prey as part of an officer exchange. As part of his hazing, he wolfed down some gagh.
* KickThemWhileTheyAreDown: Painstiks are also used in the "Sonchi" ceremony to confirm the death of an old chancellor: Contenders seeking to become the new chancellor take turns jabbing the corpse with a painstik while issuing verbal challenges. The lack of response to these insults is taken as confirmation.
* KlingonPromotion: TropeNamer and TropeMaker. Worried about your career? Just kill your Captain! The crew is required to follow anyone who bests their CO in a fair fight.
** In one episode, Dax explains the intricacies after hearing O'Brien and Bashir talk about the trope. Only a direct subordinate can make the challenge, and only after a severe infraction (cowardice, extreme failure, dereliction of duty). To be clear: you can't simply "assassinate" your superior officer, you have to challenge him to a formal duel.
** The Imperial high council is more civilized, but not by much. At least one Chancellor was poisoned by candidates vying for his seat.
* KlingonScientistsGetNoRespect: Partly justified. After all,
-->'''Martok:''' Klingons make great warriors... but ''terrible'' doctors.
** We actually see this work during the birth of Molly O'Brien, in ten forward. Worf acts as the midwife, blandly announcing the cervical dilation and getting agitated by Keiko's screaming.
-->'''Worf''' (to Keiko): "You may now give birth!"
** Lampshaded in ''Enterprise'', where 22nd Century Klingon doctors and lawyers comment on being increasingly overruled by the Warrior caste and worry about the flanderisation of their species. Towards the end of the show, in "Affliction", it’s bemoaned that Klingon science suffers from the warrior mentality.
* MartyrdomCulture: The greatest glory for a Klingon solider is to die in battle.
** Ritual suicide is often preferred over living life as a cripple, especially if you're a veteran. Even if you aren't a cripple, to allow oneself die of natural causes is a profound disgrace for a military family. No wonder Klingons are constantly hungry for the next, big war. A key point, however, is that a Klingon must die by the hand of (or with the assistance of) another. ''Unassisted'' suicide is considered completely honorless, and a one-way ticket to ''Gre'thor'' (hell).
* MenDontCry: Spock said once that Klingons lack tear ducts; however, Klingon myth states that Kahless once filled the ocean with his tears, and at least one Klingon, Kurn, has produced tears.
* NationalWeapon: The Bat'leth.
** Honorable mention goes to the "Painstik," which is [[ExactlyWhatItSaysOnTheTin self-explanatory]]. Unlike the Bat'leth, the painstiks are used mostly for ritualistic purposes. During the Rite of Ascension ceremony (essentially the Klingon bat mitzvah), a young Klingon must walk between two lines of Klingons prodding him with electrical shocks.
* NobleDemon: While their society is cruel, vicious and violent by human standards, Klingons also value Honor, Courage, Honesty and Loyalty above all else.
* NoIndoorVoice: Klingons consider it a sign of disrespect to speak softly. They like to make their presence felt.
* ProudWarriorRaceGuy: Easily the TropeMaker (at least in televised science fiction). We don't often see them interact with Alpha Quadrant races other than humans, but when they do, stand back and watch the fireworks.
-->'''Romulan:''' ''(haughtily)'' Romulans don't believe in luck.\\
'''Martok:''' All the better! It leaves more for the rest of us!
* RatedMForManly: Their idea of a bachelor party is four days of MachoMasochism. Their idea of a honeymoon is going on a hike through the nastiest terrain in the galaxy. Their idea of a joyous wedding night is for the happy couple to gleefully beat each other to a pulp. And their idea of a wedding ceremony is to tell how two mythical Klingons showed their love for each other by teaming up to sack and destroy the heavens. Isn't that romantic?
* RealLifeWritesThePlot: Klingons became the primary antagonists of Kirk's crew, in part because the makeup necessary to make Romulans was too time-consuming and costly.
* RitualSuicide: A Klingon who is unable to fight, and hence is unable to live as a warrior anymore, has the traditional obligation of committing the ''hegh'bat''. Tradition dictates that the eldest son or a close personal friend must assist. That person's role is to hand the dying Klingon a knife so that he can plunge it into his heart, remove it, and then wipe the blood on his own sleeve.
* SlapSlapKiss: Klingon foreplay... is energetic. When choosing a mate, it is traditional for a female Klingon to bite the male's face, allowing her to taste his blood and get his scent. Actually, the male comes out looking the worse for wear.
** Worf once told Wesley Crusher that per the Klingon mating ritual, "Men do not roar. ''Women'' roar. Then they hurl heavy objects." Of men, Worf said, "He reads love poetry. He ducks a lot."
* SkywardScream: In the Klingon death ritual, it's traditional for those on hand to howl into the sky as a warning to the afterlife that a Klingon warrior is about to arrive.
* SpareBodyParts: There is a good deal of multiple redundancy in their organs, a novelty they call ''brak'lul''. This allows Klingons to survive severe injuries in battle. They have twenty-three ribs, two livers, an eight-chambered heart, three lungs, multiple stomachs, and even redundant ''neural function''. It's best not to wound a Klingon unless it kills him outright.
** Funnily, Klingons are comparatively ignorant about their own biology as their medicine is poorly developed. This was largely due to warrior tradition: a wounded Klingon is expected to use the last of his strength to slay the enemy, or to kill themselves honorably.
* ThemeNaming: Klingons love the letter K. ''The Original Series'' gave us the iconic triumvirate of Kang, Kor, Koloth, and Kahless; and the movies have Kruge, Klaa, Koord, and Gorkon. And on the Enterprise, there's [[OddNameOut Worf]]. In the Expanded Universe, their home planet used to be called Klinzhai, but the official canon later renamed it Qonos (pronounced with a K sound).
* WarIsGlorious
* WildHair
* YellowPeril: Klingons are typically portrayed with dark skin and Fu Manchu facial hair suggestive of Asian peoples. In fact, the only physical description of them in the script for "Errand of Mercy" (the Klingons' first TOS story) is "oriental" and "hard-faced". Then again, budget constraints limited creativity.
** Oddly, the Klingons typically fill the DirtyCommunists role, with the Romulans standing in for China. This became more apparent on TNG, when the Romulans adopted more [[GoodHairEvilHair severe hairstyles]] while the Klingons [[VodkaDrunkenski took up drinking]].

-->''"Romulans! So predictably treacherous."''

The Romulans are a splinter group that rejected the teachings of Surak, emigrating from Vulcan to colonize the worlds of Romulus and Remus. You might consider them the anti-puritans. Interestingly, the Romulan Star Empire is very similar to that of the Roman Republic ''before'' it became the Roman Empire, with a large senate and a single committee above that. Kirk had a few run-ins with the Romulans, causing them to disappear into space to lick their wounds; they emerged as a main antagonist of TNG, [[MeetTheNewBoss effectively replacing the Klingons]].
* AlwaysChaoticEvil: Out of all the recurring antagonists in the franchise (minus the Borg) the Romulans come the closest to playing this trope straight.
* BigBad: On ''[=TNG=]''. Not as powerful as the Borg, not as slippery as the Cardassians, but more recurring than either and are behind half the evil schemes in that series. They arguably became this again on ''Enterprise'', until a planned arc involving the Federation-Romulan War was CutShort.
* BigBadassBirdOfPrey: When Surak's reforms spread rapidly across Vulcan in the 4th century, a minority rejected Surak's ideals. Those rebels marched beneath the banner of the raptor's wings, which became the symbol of the Romulan Star Empire. Their warships are designated "Bird-of-Prey" (not to be confused with the Klingon Bird-of-Prey from the same century) and the "Warbird" (24th century battleship). The latter sports a unique wrap-around design and stretches about twice as long as a Federation ''Galaxy''-class, but with a lower top speed.
* CardCarryingVillain: Nearly every other belligerent race in the Trek 'Verse has some has some lofty goal or principle they feel justifies their behavior, be it honor and glory (The Klingons), "Perfection" (The Borg), imposing Order upon a chaotic Universe (The Dominion) or ensuring their people never go hungry (The Cardassians). The Romulans lack such justifications, brazenly bragging about their superiority and LackOfEmpathy. They come the closest out of all the major races in the franchise to being evil for the sake of being evil.
* {{Catchphrase}}: A common Romulan courtesy is "Jolan Tru", similar to the Vulcan greeting. Nobody knows what it means, though.
* ChronicBackstabbingDisorder: The Romulans consider everything within their field of vision to be rightfully theirs. Accordingly, it goes against their character to honor any truce or treaty.
* CulturePolice: Unlike the Klingons, who were depicted as 'strong & silent' types before being retooled into {{Boisterous Bruiser}}s, the Romulans went in the opposite direction. On TNG, the Romulans became much more rigid in style and demeanor, echoing Communist China upon which the new Romulans were based. This goes for the females, too. (No more long-legged {{femme fatale}}s, like the ones we saw in TOS and ''Film/StarTrekVTheFinalFrontier''). The Tal Shiar is everywhere, and everyone dresses inconspicuously on Romulus to avoid attracting their attention. They are the modest utilitarians to Cardassia's Gucci-wearing aesthetes.
-->'''Garak''': ''(grimly reminiscing)'' "Ah, yes, Romulus. How well I remember it. You'll find the predominant color to be grey: The buildings, the clothes, the people. Did you know that the Romulan heart itself is grey? It's true. And altogether appropriate for such an unimaginative race."
* EarthShatteringKaboom: In the 2009 film, a star close to Romulus goes supernova. Although Ambassador Spock attempted to prevent the supernova from striking the planet using red matter, he was ultimately unsuccessful and Romulus was blown to bits. Couldn't have happened to nicer people.
** LaserGuidedKarma: Had the Romulan government agreed to Spock's reunification plans with Vulcan, they likely would have been saved sooner.
* EnemyMine: With an alliance with the Cardassians, and a neutrality agreement with the Romulans, the Dominion had the Federation on the ropes. Captain Sisko realized they couldn't fight the war without help, and needed to convince the Romulans that their truce with the Founders would not last. To that end, he cooperated in [[spoiler:assassinating a Romulan Senator and pinning it]] on the Dominion. [[TheExtremistWasRight And it worked!]] How very ''[[NotSoDifferent Romulan]]''.
-->'''Garak:''' And the more the Dominion denies their guilt, the more the Romulans will believe they're guilty, because that's ''exactly'' what they would have done in their place!
* EqualOpportunityEvil: Some of their top-ranking officers and politicos are women. They had an Empress at one point according to Q.
** Romulans also have gotten rid of the very unsavory side of their Vulcan heritage. They've genetically removed the Pon Farr and as such no longer partake in Vulcan rituals where a woman could have a man challenge her fiance to a duel to the death and end up with a man she's forcefully married to and have sex with.
* EvilCounterpartRace / ShadowArchetype: To Vulcans.
* EvilEyebrows: Theirs are accentuated by a distinct, "V"-shaped forehead ridge. In the films, the ridges are completely gone, but the eyebrows are still longer and hairier than the Vulcans.
* DrinkOrder: Romulan ale (or "Kali-Fal") is a blue alcoholic beverage which was made illegal due to a trade embargo in Kirk's time. However, the embargo is lifted when the Rolumans agree to help drive out the Dominion.
* TheFaceless: Romulans were aware of Humanity for some time before Earth knew of them. Infiltrating the highest levels of the Vulcan High Command, the Romulans got a full scope of Earth's capabilities. The Enterprise NX-01 inadvertently encountered a Romulan minefield at one point, officially the first time Humanity became aware of the Romulans. Even after fighting the Earth-Romulan War, it wasn't until the 23rd century that Humans actually saw the Romulans without their helmets on. (ENT: "Minefield"; TOS: "Balance of Terror")
* FantasticRacism: The Romulans believe themselves to superior to everyone, and still cling to the idea that that one day, the Romulan Empire will rule the entire galaxy. (TNG: "The Neutral Zone", "Data's Day", "The Enemy") According to Miles O'Brien, there was no piece of technology that the Romulans didn't claim they invented before everyone else.
* FashionableAsymmetry: In their TOS apperances, the male Romulans wore gold togas with a sash over their shoulder. (Violet sashes for commanders, blue for the worker bees.) The ladies, however, wore form-fitting uniform with a violet sleeve.
* FlipFlopOfGod: ''Trek'''s star charts place the Romulan Empire into the Beta Quadrant of the galaxy. However, in ''Deep Space Nine'', they are changed to an Alpha Quadrant power to include them in the Dominion struggle.
** The loose explanation they came up with is that the capital planets of the Romulans and Klingons are in the Alpha Quadrant, but most of their empires are located in the Beta Quadrant. The dividing line between Alpha and Beta runs through Earth. Most of the Federation is in the Alpha Quadrant, but parts spill over into the Beta Quadrant. If the disk of the galaxy is viewed top-down with Earth at the bottom, the Romulans and Klingons are "east" of the Federation, while the Cardassians are "west". The Romulans are located core-wards from the Klingons (which also explains why advanced Borg scouting attacks hit both the Romulans and Federation, but not the Klingons).
* LadyOfWar: As said several Romulan military commanders are female. When presented as a WorthyOpponent they will likely be this.
* LetNoCrisisGoToWaste: The image-conscious Romulans prefer to play a waiting game with their opponents, attempting to trick them into breaking – or appearing to break – an agreement so as to give them a solid justification for striking.
* ManBehindTheMan: If some villain is implied to have a secret benefactor, the benefactor will probably be the Romulans. Especially if the villain is a Vulcan or a Klingon, just to show how traitorous or gullible they are as both species regard the Romulans as long-standing enemies.
* ManipulativeBastard: They spend a lot of their screen-time on ''Enterprise'' setting the Alpha Quadrant's major players against each other.
* OfficerAndAGentleman: In the novels, they often come across as dignified and ultra-conservative aristocrats rather then simply as bad guys, though the Romulan commanders that appear on TV sometimes do have that aspect to them. The more 'admirable' ones seem to behave this way.
* ProudWarriorRaceGuy: More like a Proud Soldier Race, mind, given their disciplined and strict way of life.
* SecretPolice: Known as the Tal Shiar.
* ShouldersOfDoom: The infamous "mattress cover" costumes used on TNG.
* SlaveMooks: Unlike the first colony world of Romulus, Remus was a harsh planet notable only for its dilithium deposits. The Remans were subjugated and forced to mine ore to fuel the fledgling empire.
* SpaceColdWar: Throughout the franchise, they are depicted as frosty, Machiavellian schemers who are always at war/in an uneasy truce with the Federation.
* SpaceRomans: They have a Senate, they're ruled by a Praetor... in the original series, they had a rank of Centurion and bronze-ish helmets, too.
* SpikesOfVillainy: Their soldiers wear bandoleers lines with spikes.
* StealthInSpace: The Klingons originated it, but the Romulans almost never fly anywhere without the cloak permanently switched on.
* StrawmanEmotional: Disagreed with Surak's logic and left to start their own, more amoral, militaristic society.
** Though overall, they are still very composed and disciplined. Ironically despite their imperialistic empire, they seem to contradict the idea that Vulcans who don't control their emotions are a dangerous menace, since on a personal level they rarely if ever violently lose their temper or hint at uncontrollable emotions. In-universe this is attributed to their lack of suppression; there is no emotional build-up to blow off when they lose their cool.
* TokenEvilTeammate / AloofAlly: In their EnemyMine alliance with many other Alpha Quadrant powers to combat the Dominion.
* WorthyOpponent: Several of the most memorable Romulan characters in the original series, as well as a number of times in the novelizations.

->''"It's never been all that hard to figure out what I'm thinking."''

Andorians are native to the snow-covered moon Andoria, which orbits a blue, ringed gas giant. Andorians first appeared in the TOS episode "Journey to Babel", and have been seen or mentioned in episodes of subsequent series. They did not rise to prominence until ''Star Trek: Enterprise'', which takes place before the Andorians become one of the founding four races who establish the Federation. Andorians are swashbuckling romantics, exhibiting [[EmotionsVsStoicism intense dislike for and mistrust of logic]]. They can be found harassing their idealogical opposites, the Vulcans.
* BeneathTheEarth: Most of their cities are built underground, mainly to take advantage of geothermal power.
* BizarreAlienSenses: The antennae on the head of an Andorian helps maintain their sense of balance.
* BlueBlood: Andorians are true bluebloods, both in the sociological and [[AlienBlood literal sense]]. Their society values reputation and familial honor, to the point of carrying on vendettas over ancestral disputes. Though they aren't known for charity, they are compelled to repay any debts they owe.
* BreakTheHaughty: The Andorians tried their hand at being an imperial power, but are mostly humiliated by Archer's crew and sent packing.
* FantasticRacism: Andorians are (yet another) xenophobic race, using the pejorative "pink-skin" to refer to humans.
* HotBlooded: Though their natural environment [[SingleBiomePlanet is almost entirely made of ice]], Andorians are easily agitated and very passionate. This provides something of an interesting contrast to the Vulcans, who come from a desert planet and are known for their cautious demeanor and restraint.
* HyperactiveMetabolism: Their heightened metabolism allows them to thrive in extreme climates as cold as minus 28 degrees Celsius, or survive for at least two days under boiling hot conditions. However, it renders them highly susceptible to infection: simply being grazed by a phase pistol beam can lead to a fatal injury. It also makes them fearsome combatants, though sustained physical activity will exhaust an Andorian more quickly than it would a human.
* ImprobableWeaponUser: Andorians settle matters of honor through duels using an ice mining tool called the ''ushaan-tor'', which looks like a cross between a knuckleduster and a fleshing knife.
* TheNapoleon: Andorians are short and irritable. They overcompensate for their stature with loud threats and gunfire. (Jeffrey Combs modeled his performance as Shran on JamesCagney.)
* NotSoDifferent: In ''Enterprise'', the growing realisation of this between Archer and Shran was part of what lead the Andorians to enter diplomatic talks with Humanity, noting their similarities as highly stubborn, yet honourable, men of their word, who serve on starships named after important vessels from history.
* ProudWarriorRace: Service in the Andorian Imperial Guard can strongly influence one's social standing.
* TookALevelInDumbass: The Andorians were depicted as conniving diplomats on TOS. They were later retconned into overgrown teen rebels fighting against Vulcan dogmas. [[TheLonelyIsland They ain't a part of this system!]]
* WeaksauceWeakness: Loss of an antenna will badly disorient them, to the point of temporary incapacitation.
** GoodThingYouCanHeal: However, the antenna will grow back after a period of nine months, which can be reduced by applying electrodes and massages to the affected area.



->''"Tellarites do not argue for a reason. They simply argue."''

Along with the Humans, Vulcans and Andorians, founding members of the United Federation of Planets. Forthwright pig-like aliens with broad bodies and bushy beards, they thrive on argument.
* BlueAndOrangeMorality: Blustering insults represent formal politeness; a conversation begins with complaints and insults.
* HufflepuffHouse: One of the founding races of the Federation, but get very little screentime or mentions.
* JewsLoveToArgue
* OurDwarvesAreAllTheSame: Short, hairy, and with a bad attitude, the Tellarites are Space Dwarves to the Vulcans' SpaceElves.

!!Species debuting in ''The Animated Series''


->''"The least claw may be the sharpest, should it be joined with others."''

Humanoid cats, [[DescriptivelyNamedSpecies as the name would suggest]]. Caitians can vary in color from brown to black, and the females speak with a [[VerbalTic purring quality]].
* AttentionDeficitOohShiny: A Caitian Duty Officer in ''Star Trek Online'' has {{Flavor Text}} implying a certain amount of this.
-->"My time in the Collective honed me. I am more focused on-- [[HypocriticalHumor hey that light is blinking]]."
* CanonImmigrant: Caitians were among prominent new species of [[StarTrekTheAnimatedSeries the animated series]]. Caitian admirals appear in ''Film/StarTrekIVTheVoyageHome''.
* CatFolk
* CatSmile: The CatGirl Lieutenant M'Ress had one constantly.
* DoesNotLikeShoes: Some Caitians did not find it necessary to use footwear.
* MultiBoobage: ''Film/StarTrekVTheFinalFrontier'' featured a gratuitous, triple-breasted cat lady doing a table dance, though it's unclear if she's of the same species.
* NeverHeardThatOneBefore In ''StarTrekNewFrontier'', Caitian officer M'Ress grouses that she's heard all the cat-related jokes in existence.
-->"So let us be clear with one another, Admiral. [[HurricaneOfEuphemisms I have one life, not nine. I have never been killed by curiosity, my parents do not live in a cat house, my mother did not rock me as an infant in a cat's cradle, the preferred Caitian method of self-defense is not cat-boxing, I do not deposit my earnings into a kitty, if I am trying to be delicate about a subject I do not pussyfoot around]] - shall I go on?"

!!Species debuting in ''The Next Generation''

->''"Humans constantly think one thing and say another."''

Betazoids are mostly indistinguishable from humans, the only difference being that the iris of a Betazoid's eyes is bigger than a human's. Betazoids are willfully empathic and telepathic (unlike the Vulcan mind-meld).
* BewareTheSillyOnes: Betazoids quickly become unstable if their empathic abilities are hampered in any way, as it is their primary mode of communication. Tam Elbrun was born without the ability to filter out unwanted thoughts, which ended up botching a sensitive FirstContact and getting 47 Starfleet officers killed. Even Counselor Troi unraveled when her empathic powers temporarily switched off. (TNG, "Tin Man", "The Loss")
** The only Betazoid member of ''Voyager's'' crew, Lon Suder, had no empathic or telepathic abilities, perhaps explaining his innate desire to kill things. He joined up with Chakotay's Maquis unit, but was ostracized when he proved too violent even for them.
* {{Bourgeois Bohemian}}s: They don't keep pets and prefer shuttle travel to mounted animals because they empathize too much with them.
* TheEmpath: Children who are only part-Betazed, like Deanna, still have this ability.
* ExoticEyeDesigns: [[HumanAliens Betazoids]] have black irises.
* MauveShirt: The entire planet was seized by Jem'Hadar during the Dominion War (offsceen, mind you). The writers batted around the idea of Vulcan being occupied, but decided against it. Ironically, J.J. Abrams would later blow Vulcan to pieces.
* MindOverManners: Due to their telepathy, Betazoid culture embraces honesty to a point considered rude by other cultures, namely humans. Lwaxana Troi, a particularly strong-willed Betazoid, commented on her befuddlement at the Human practice of fibbing to spare others' feelings or for politeness' sake.
* MrsRobinson: A Betazoid women's sex-drive quadruples when they reach a certain age, meaning that half of the population of Betazed literally consists entirely of cougars.
* NakedPeopleAreFunny: In Betazoid wedding ceremonies, all participants (bride, groom, and guests) are traditionally nude. Poor Picard.
-->''(grumpily)'' "I'll be in the gym."
* NewAgeRetroHippie: Their culture greatly resembles the New Age movement on Earth, to obnoxious degrees.
* PokeInTheThirdEye: Mature Betazoids sometimes suffer from Zanthi fever, which caused them to lose control over their empathy and absorb everyone's collective thoughts at once.
* SuspiciouslySimilarSubstitute: The Betazoids were inspired by the Deltans from ''Star Trek: The Motion Picture''. Their similarities include the Betazoid species having been named after a letter of the Greek alphabet, the Betazoids' relatively very open attitude toward sexual activities, and the species' ESP.

[[folder:Q Continuum]]
-->''"As the Q have evolved, we've sacrificed many things along the way; not just manners, but mortality and a sense of purpose and a desire for change and a capacity to grow. Each loss is a new vulnerability, wouldn't you say?"''

The Q Continuum refers not to a race, but an extra-dimensional plane inhabited by a race of non-corporeal, godlike beings known as the Q. Their attitude toward the affairs of "lower" beings is one of general indifference, with the exception of squashing species they deem too dangerous, like Humans (but never the Borg, conveniently enough). From what little we see of the Continuum, it's similar to the Greek pantheon.
* AscendToAHigherPlaneOfExistence: Q hinted early on that his species were once not unlike bipeds. This was later confirmed by Quinn, who (unlike Q) had no reason to lie. Picard speculates that Q might be testing humanity because he thinks we have the potential to one day evolve into beings like the Q, and he is afraid that we might turn out wrong.
* AssInAmbassador & MouthOfSauron: Q interests regarding the human race are normally handled by a single representative. This individual has a history of insulting, tormenting, taunting, and otherwise harassing races all over the galaxy..
* BroughtDownToNormal: A common punishment for if a Q breaks the law is to spend the rest of their lives as a mortal being. One Q in particular was temporarily turned human as punishment for making the Borg aware of the Federation.
* CreativeSterility
* HumanityOnTrial: Part of the reason they tend to interfere with humans. When Q first appeared, he took on the appearance of Ollie North (referencing the [[RonaldReagan Iran-Contra]] arms deals) and a drug-infused space trooper from the future. Earth's been warlike for most of its existence, and it could fall back into old habits very easily.
* ImmortalImmaturity: A trait TNG's Q is infamous for - though his straight-laced friend, [=Q2=], had a surfer bum quality of his own.
* ImmortalsFearDeath: Most of the Continuum find mortality terrifying, and they imprisoned Quinn rather than let him go through with his suicide.
* JerkassGods: Whenever they assume human form, they always make a point to wear ''the highest-ranking uniform in the room''. Q even cycled though an Admiral's and Marshall's clothes, just to irritate Picard (a Captain, albeit one of a flagship).
** From knowledge gained in her extensive travels and long life, Guinan points out that ''most'' of the Q are actually responsible and benign beings who mind their own business, and find it immoral to interfere in the lower planes of existence, much as the ''Enterprise'' will not interfere with primitive hunter-gatherer aliens. The Q who visits the ''Enterprise''-D is just a jerkass even by their standards (to the point that once they even briefly stripped him of his powers because he kept using them irresponsibly). If the Q are Asgardians, the Q who pesters humanity is their Loki - a trickster who stirs up trouble (though he gets more well-intentioned as he goes along).
* MeetTheNewBoss: According to second-hand sources, Q was inspired by Trelane, a [[GooGooGodlike childlike-yet-omnipotent]] trickster from TOS who shared Q's taste for medals and epaulettes.
** Some fanon and even licensed (but non-canon) works have retconned Trelane into being a member of the continuum, if an immature one.
* TheOmnipotent / TheOmniscient: Q is a lower version of this; while he claims omnipotence, other Q can still hurt him or take away his powers.
** Quinn politely admits to Janeway that despite Q's bluster, the Q are not actually "gods". Moreover, he says that while they are ''practically'' "omnipotent", this is for every possible frame of reference to human comprehension. They can make entire galaxies explode with a thought, or with a snap of their fingers turn the entire Borg Collective into cute puppies. But Quinn insists that up in the higher planes of existence in the Q continuum, there are still things they can't do, though such things are beyond our comprehension or description. He is much more modest about his race than Q is.
* PlanetOfSteves: Nearly ''every'' member is named "Q" or has a Q in their name somewhere. In fact, all Q address other Q simply as "Q", and every other Q knows who that Q is talking to without elaboration.
* RealityWarper: Big time. Even the babies are capable of altering the orbits of entire ''planets'' just days after birth.
* SpacePolice: They're god-like beings who can easily wipe out entire galaxies out of boredom, but they do have the universe's best interest in mind.
* SufficientlyAdvancedAliens: Rumors persist in some Trekkie circles that the Q are not as powerful as they say; it's all just smoke and mirrors.
* UnusuallyUninterestingSight: During their first encounter with Q, the Enterprise-D crew acknowledged he was potentially dangerous, but failed to find him at all awe-inspiring. Picard outright implies that the Federation had already become accustomed to dealing with pushy, god-like energy beings (which, if Captain Kirk's career is anything to go by, is quite true).
* WhoWantsToLiveForever: Quinn sought to kill himself rather than be stuck with these people for one more second. The Q do not even acknowledge each other, having exhausted all conversation over the eons. Horrifying.
** LivingForeverIsAwesome: That said, renegade [=Qs=] seem to really enjoy it. After all, Q (De Lancie) viewed being turned mortal a FateWorseThanDeath.
* YouCannotGraspTheTrueForm: A non-malevolent variation. Mortals can't perceive the Q in their natural appearance, to say nothing of the realm they inhabit.

-->''"They're greedy, misogynistic, untrustworthy little trolls, and I wouldn't turn my back on one of them for a second."''

The used car salesmen of the galaxy, swindling unwary customers and measuring everything in terms of profit. They first appeared in "The Last Outpost", the fifth episode of TNG, as a potential Big Bad, but were quickly downgraded to [[HarmlessVillain comic relief villains]]. Known for their business acumen and rampant misogyny, forcing their women to remain naked (to prevent them from working). Originally a parody of modern-day humans ([[ThisLoserIsYou gee, thanks]]), the Ferengi gradually began to exhibit some of our virtues, as well.

* AbstractApotheosis: Raw capitalism at its best. And worst.
* AcceptableTargets: The Ferengi value profit and commerce above all else, and even revere its presence in other races. They are a realistic depiction of what a pure Libertarian society would be like, minus the gender equality (at least until Zek granted suffrage at the behest of his wife).
* AlienLunch: Ferengi are big insectivores, and the jingle for their version of Pepsi is about how slimy it is because it contains algae.
* AllTrollsAreDifferent: Butt-ugly? Check. Obsessed with gold? Check. Untrustworthy? Check.
** As the species mellowed out in the nineties, they began to incorporate some {{hobbit|s}} traits, including their dome-shaped clay huts which definitely draw inspiration from Tolkien.
* AlwaysChaoticEvil: Originally portrayed this way on [[Series/StarTrekTheNextGeneration Next Generation]], but this ceased to be the case later in that series and on [[Series/StarTrekDeepSpaceNine Deep Space Nine]].
* BigBadWannabe: A RealLife example. The Ferengi were built up as the over-arching BigBad of TNG, a reflection of humans when they [[EvilCounterpart were still avaricious and violent]] -- but they never came across as anything more than buffoons. The writers eventually wised up and stopped taking them seriously.
* BizarreAlienBiology: Ferengi kids shed their baby ears, rather than teeth. Eek.
* BlueAndOrangeMorality: The Ferengi value {{street smart}}s and business savvy over an honest transaction. They're known for slipping dubious clauses and [[ReadTheFinePrint disclaimers]] into their contracts (for instance, an obscure provision buried on Page 21, Subsection B, Paragraph 12 stated that Quark was entitled to feel up his Dabo girls). That said, they can justify cheating, tricking, and swindling their customers only within the confines of The Contract. Pointedly, Rule of Acquisition #17 sternly reprimands, "''A contract is a contract is a contract.''" Under Ferengi law, any Ferengi who breaks a signed contract with another Ferengi automatically has their assets liquidated by the FCA and is blacklisted within merchant circles.
* CharacterizationMarchesOn: A race that originated as a caricature of the worst parts of capitalism ultimately became more rounded-off and sympathetic as time went on.
** When the time came to have a Ferengi as a series regular, Quark rejected the whole notion of his people being a 'backward' race. (After all, the Ferengi don't have anything resembling death camps in ''their'' history.) This was later retconned as propaganda on the part of the Ferengi government, which was frightened by the idea of Federation culture rejecting the acquisition of wealth as a goal and wanting to keep them at arms length in order to come up with a way of interacting with them.
* ChildrenAreAWaste: The Ferengi consider pregnancy to be a rental, with the father being termed the lessee.
* CityOfGold: The Divine Treasury, exactly what it says on the tin. (Though in this case, it's latinum, not gold.) Possibly; the only time we've seen it is in a dream sequence and the ''dreamer'' thinks it's tacky.
* CorruptCorporateExecutive: The more successful examples... (Quark's cousin bought his own moon.)
** HonestJohnsDealership: ...and the less. Starfleet instructors specifically warn their fledgling officers about Ferengi hucksters they may come across in ports.
* TheDandy: When you're under five feet tall, you have to dress to impress. Ferengi take their wardrobe as another opportunity to flaunt their success; some even wear bars of latinum around their necks.
* DirtyCoward: Ferengi are cowardly by nature. Their official hand gesture looks suspiciously like a animal in submission.
* DoYouWantToHaggle: A Ferengi's idea of self-defense is to offer continually-higher bribes. Not a bad strategy within the Ferengi Alliance... but the failure rate is quite high with Klingons, et al.
* EnergyWeapon / WhipItGood: Ferengi soldiers are shown packing stun whips (!) on two occasions: Once in TNG and again on ENT. It's got great range and negates the height difference between them and their opponents.
* EvenBadMenLoveTheirMamas: ''Never'' make fun of a Ferengi's mother. Rule of Acquisition #31.[[note]]There is some debate as to whether or not it is followed with [[SubvertedTrope "Insult something he cares about instead."]][[/note]]
* [[EvenEvilHasStandards Even Swindlers Have Standards]]: Genocide and slavery are completely unknown in Ferengi history, nor have they ever engaged in a major interstellar war. They feel this makes them morally superior to ''the Federation''. Because Ferengi society places such emphasis on material success and outsmarting others, violence carries a stigma of failure -- to be used strictly when defending family members or when there are no possible avenues of escape. Traveling throughout the Alpha/Beta Quadrants also requires a degree of open-mindedness: While they can be a bit bigoted (there's no love lost between them and hew-mons), racism is an alien concept to the Ferengi. Why would a Ferengi merchant pass up a chance for profit based solely on their customer's race? Equally, revenge and crimes of passion are nearly unknown among Ferengi; again, they rarely see any profit in either.
** Racism is abhorrent to Ferengi: in Season 1 of DS9, when mob opinion suspects Odo of a murder purely based on anti-changeling racism without hard evidence, ''Quark'' of all people is the only one who openly declares his disgust at everyone else. When it's pointed out that he is Odo's perpetual enemy, he bitterly says he is, but compared to everyone else, that makes him the closest thing Odo has to a ''friend''.
** Oddly enough despite this they're the most sexist race in the series. They finally undergo a women's lib movement on [=DS9=].
* EveryManHasHisPrice: Rule of Acquisition #98.
* EvilVirtues: Ferengi are nothing if not penny-wise. Every bar of latinum they spend is invested into further means of generating profit.
** In fact, going into debt is considered a mortal sin.
--->'''Rom:''' You don't think we're in that... [[{{Hell}} other place?]]\\
'''Nog:''' The Vault of Eternal Destitution?!\\
'''Quark:''' Don't be ridiculous! ''(terrified)'' The bar was showing a profit!!
* ExoticEquipment: A Ferengi male will invariably try persuading a female of another race to massage his ears. They frequently leave out the part about Ferengi ears being sexually stimulating. This practice is called ''Oomox'', and there are entire ''Kama Sutra''-sized tomes dedicated to it.
* FantasticSlur: "''Philanthropist!''"
* GoldFever: Inverted. Like most races in the Alpha Quadrant, they accept gold-pressed latinum as barter, but the latinum carries real value.
** Predictably, their religion is based on the principles of capitalism: they offer prayers and money to a "Blessed Exchequer" in hopes of entering the "Divine Treasury" upon death, and fear an afterlife spent in the "Vault of Eternal Destitution". Several expanded universe sources mention that the Ferengi see Earth's now-defunct Wall Street as some kind of holy site.
* HyperAwareness: Ferengi have perhaps the best hearing of all the Trek aliens, able to determine how many decibels the volume in a room is.
* IntimidatingRevenueService: The Ferengi Commerce Agency (FCA). These bozos have jurisdiction over any Ferengi business anywhere in ''the universe''. They police Ferengi ideologies, such as union-busting, with zeal seldom seen outside of the mafia.
** To be fair, though, the only FCA representative we meet is Brunt, who is confirmed to be particularly rabid and amoral in his duties, and despised by the Grand Negus.
* MadLibsCatchphrase: The Rules of Acquisition, of which there are over [[ two hundred]]. Possibly the only code of honor the Ferengi follow.
** Subverted by the Rules themselves turning out to be another scam -- at least in Quark's dream.
-->"Would you buy a book called ''Suggestions of Acquisition''?!"
* MeaningfulName: The name "Ferengi" is a corruption of the word "farhang," which was a derisive word used in some parts of Southeast Asia to describe European [[strike:colonialists]] merchants.
** Variations are used across Asia, ultimately all distortions of the word ''Frank'', i.e. somebody from France, mistakenly interpreted to mean all Europeans.
** "Ferengi" was also the name of a princess in the Persian ''Shah Nameh'', in keeping with the Star Trek practice of naming races after mythological figures.
* MoneyFetish: Ferengi ears are said to tingle whenever they sense opportunity. Indeed, you can see them involuntarily stroke their ears when large sums are read aloud... wait, how does one perform ''Oo-mox'' again?
* MrViceGuy: On their better days. As Jadzia put it, they're plenty of fun if you accept you can't turn your back on one for a second.
* MySisterIsOffLimits: Rule of Acquisition 112: Never sleep with the boss's sister.
* ProudMerchantRace: The most triumphant example in Star Trek.
* PsychicBlockDefense: [[Series/StarTrekTheNextGeneration Data]] says that Ferengi are naturally immune to TheEmpath. Whether this extends to other types of PsychicPowers (Like a Vulcan Mind-Meld) is never explored.
* {{Reconstruction}}: After being introduced as Big Bad Wannabes, [=DS9=] showed how they could function as an actual society.
* RoswellThatEndsWell: Turns out it was Quark's contraband-carrying shuttle which crashed in New Mexico, sent back in time via an accident. ([=DS9=]:"Little Green Men")
* RuleNumberOne / ScoundrelCode: The Rules of Acquisition, which range from harsh ("A Ferengi without profit [[NoTrueScotsman is no Ferengi at all.]]") to pragmatic ("You can't make a deal if you're dead.") to PetTheDog ("Good customers are as rare as latinum. Treasure them.")
* SentientCosmicForce: The Great Material Continuum! Ferengi visualize it as a great river flowing throughout the cosmos, bartering goods and services between those that need them. A good Ferengi knows how to "navigate" this river to turn a profit. (O'Brien compared it to rough water rafting when Nog roped him into a risky deal.)
* TheSoCalledCoward: Whilst it's true that most Ferengi are relatively cowardly; if you do manage to piss one off they are extremely cunning, are perfectly fine with fighting dirty and at least a few possess strength equal to that of a Vulcan (Quark once snapped a gold brick in half using nothing but ''his bare hands'' and another one effortlessly threw Riker several meters). They also have an impressive navy with starship weapons capable of taking out a Galaxy class given the right circumstances and the best shields money can buy.
* SpacePirate: Their original characterization when they were planed to be serious villains. Implicitly {{Retcon}}ned to be just a few who couldn't make it in "legitimate" business.
** StupidCrooks: Said pirates frequently prove to be no better at crime than they were at mercantile pursuits.
* StrangeSalute: Ferengi bow and point their palms outward, like a possum.
* SwampsAreEvil: Ferenginar, a world which has no word for "crisp". But they ''do'' have over two hundred words for "rain".
* [[StrawCharacter Straw Capitalists]]: While later series rounded them off, their "hat" remained firmly in place.
* TertiarySexualCharacteristics: The females of their species have (relatively) smaller earlobes. This was revealed in an episode where a Ferengi girl [[SweetPollyOliver wore prosthetic ears]] to fool the boys' club (and nearly got away with it, too!).
* ThisLoserIsYou: WordOfGod paints the Ferengi as 21st-century humans, particularly Anglo-Saxons.
** Turned on it's head a little though, if Quark can be trusted, in that while Ferengi are greedy as a virtue and sexist/xenophobic as a culture, they've also never taken it to the same extreme that humans have, citing that the Ferengi never had concentration camps, slavery or massive-scale warfare.
* ToWinWithoutFighting: See this comment from "Body Parts":
-->"We're not Klingons. We're ''[[LetsFightLikeGentlemen businessmen]].''"
** In particular, Quark states that the Ferengi would have hammered out a mutually beneficial deal with the Dominion (and given them a little something for their trouble, say Betazed), as opposed to the Federation's "independence at any cost" stance. Though in the episode Quark says that in, he guns down a Jem'Hadar soldier who was coming to [[PapaWolf kill his nephew]]. This serves as a possible microcosm into Quark's attitude, in that negotiation only works if the other side doesn't find killing you and taking your stuff easier than negotiation...
** In "The Maquis". Quark determines that the Cardassians, caught with their hand in the till, would back off on arming their settlers, who in turn would be open to peace negotiations with their Terran neighbors. In essence, the Ferengi are using Game Theory to deduce the best possible outcome for all parties; Quark even manages to convince a ''Vulcan'' resistance fighter that his logic is sound!
* WarForFunAndProfit: Ferengi Rule of Acquisition #34 states "War is good for business". However, Rule of Acquisition #35 rebuts "[[OnSecondThought Peace is good for business]]." Basically, this entitled Ferengi to sell guns to both sides of a conflict, but also notes that it's a bad idea to lose a customer, and that any war that goes on for too long will have a negative impact on commerce.


The {{spear carrier}}s of the galaxy, Benzites are usually seen pottering around in the background in each iteration of ''Trek'' - though two of them had speaking roles on TNG. They lost the breathing apparatus in [=DS9=] (explained away in ''Star Trek Online'' as cosmetic surgery for select Benzites who spend a lot of time in oxygen-rich ships), and even their skin color has been subject to change, ranging from amphibian green to purple.
* CannonFodder: Benzar was one of the Federation planets to fall to the Dominion, along with Betazed. However, the Benzites had the misfortune of being 'liberated' by the Romulans, who had joined the war effort. Constable Odo expressed doubt that the Romulans would give it back, considering their extreme reluctance to surrender any territory they acquire.
** Although by Online they're back in the Federation.
* ControlFreak: Benzites are highly meticulous, a characteristic reflected in their regulations, which states that no officer on a Benzite ship is to report on anything without providing a full detailed analysis ''and'' solution. This got under the ''Enterprise'' crew's skin when an exchange student kept overstepping his bounds. (TNG: "A Matter Of Honor")
* DependingOnTheWriter: Each script or novel seems to have its own take on Benzite physiognomy. The ''Sky's the Limit'' short story "Acts of Compassion" states that Benzites breathe in a gas heavy in chlorine, while the Pocket [=DS9=] novel ''Devil in the Sky'' claims their blood is both orange and rich in mercury and platinum.
* FishPeople: The Creature From the Black Lagoon, if he enlisted in the Navy.


Bolians evolved from porpoise-like mammals. Some of them have hair, though this is rare, and probably has to do with continuity goofs. Bolians of both sexes (bald or not) are generally cheerful and noted for their HeadbuttOfLove. Oddly, they appear in Trek mostly as cooks as servants; A running gag is the ''Enterprise-D'' employing a bald Bolian as its hairdresser. They're not all small-timers though; the Bank of Bolias is huge and a serious competitor for the Ferengi.
* AlienBlood: Like Vulcans, their blood is blue because it uses hemocyanin to carry oxygen. However, attempting to give a transfusion between the two is not possible without extensive genetic modification of the blood sample.
** Furthermore, Bolian body chemistry is hinted to be somewhat reactive, to say the least. Apparently, [[BoldlyComing intimacy with a Bolian]] can result in some adverse side-effects for humans, and then there's that whole thing about their eating habits that would necessitate strong stomach acids and saliva. There's also a RunningGag about how important it is for Bolians to have access to good plumbing. Ick.
* AlienLunch: Bolian cuisine is regarded as being quite tasty, but the preparation of some dishes involve the use of ''rotten meat'' and they're capable of eating foods that may be regarded as toxic to some species.
* BigFun: The Klingons have Honor, the Changelings have Order, the Ferengi have Profit. The Bolians' [[PlanetOfHats Hat]]? Frivolity. Nearly every Bolian we meet represents some highly elastic [[IncrediblyLamePun enterprise]]. Accordingly they're generally depicted as jolly, and tend to be a bit pudgy.
** They are not, however, without avarice: one Bolian publishing agent exploited the legal non-status of holograms as sentient beings to commit intellectual property theft.
* ExtremeOmnivore
* HiddenDepths: Despite their prominent portrayal as service industry workers, the Bolians are apparently a major economic force in the Alpha Quadrant.
* ProudMerchantRace

-->''"We are the Borg. Lower your shields and surrender your ships. We will add your biological and technological distinctiveness to our own. Your culture will adapt to service us. Resistance is futile."''

The Borg are a collection of species that have been [[UnwillingRoboticisation robotocized]] into mindless drones by the Collective. A pseudo-race, dwelling in the blackness of the Delta Quadrant, the Borg use {{nanomachines}} to "assimilate" beings into their collective and wire them to the hive mind. The Borg has no ultimate goal other than to achieve "perfection", assimilating the unique traits of other species and discarding what they don't need. They represent a dark side of the Federation's collectivism.

* [[AlwaysChaoticEvil Always Lawful Evil]]: So long as they are a part of their collective, they are subject to its will.
* ArmCannon: A rare departure for Trek, as most species use handheld weapons. However, the drones are almost never seen using them; there are very few situations where drones could not overwhelm their targets through [[ImplacableMan brute force]] or [[WeHaveReserves sheer numbers]].
* AssimilationPlot: Their entire species is devoted to it, along with countless others.
* TheAssimilator: They move from world to world, taking "technological and biological distinctiveness" and adding it to themselves.
* AboveGoodAndEvil: The Borg sincerely think they're doing you a favor. After all, once they reach perfection, so will you... once they've "improved" you.
* BeePeople: Low-level mooks are "drones", and their commander is euphemistically called the [[HiveQueen Queen]].
* BiggerBad: Of ''TNG'' and subsequent shows. Note that the majority of Captains (excluding Kirk and Archer) have had personal vendettas against the Borg Collective: Picard was raped physically and mentally; Sisko lost his wife in the infamous defeat at Wolf 359; and Janeway is noted for her numerous [[DealWithTheDevil Devil's bargains]] with the Queen.
* ClingyCostume: Hope you like black.
* CyberneticsEatYourSoul: Especially when said cybernetics are '''optimized''' for the job.
* DangerouslyGenreSavvy: Emphasized in "The Best of Both Worlds." Riker's increasingly desperate attempts to buy his crew more time though protracted negotiation are instantly seen by the Borg for what they are.
* DeflectorShields: The built-in, personal variety. Made even nastier in that they can adapt to threats just like the rest of their technology.
* TheDreaded: Starfleet considers them the most dangerous potential threat to the Federation due to their advanced technology, relentless tactics, and no-negotiations mentality.
* EqualOpportunityEvil: The Borg are the most powerful and feared power in the galaxy, without really being a true ''race'' at all. However, it is unlikely that they would let a frail species, such as an Elaysian, waltz into combat as an attack drone.
** It's more likely that frail species that are assimilated are upgraded through their cybernetics to become much stronger; Assimilated human drones have enough power to knock a Klingon on his ass.
* EvilCounterpart: To the Federation. In some ways, they make for a better comparison than the Dominion, as they aspire to being a uniform society under one banner, rather than an empire of subjects. Unlike the Dominion or Federation however, the Borg do not operate under any code of conduct; what morality they possess considers the assimilation of a starship's crew as equal to the assimilation of an entire race. Moreover, any race that is subject to assimilation loses all semblance of identity and becomes no more than part of a single, homogeneous whole.
* EvilIsBurningHot: The Borg like to operate with a constant temperature of 39.1 °C (102.38 °F), with 92% humidity. Odd, given the fact that the average Borg vessel is like a giant CPU, and most modern computers function more optimally at lower temperatures.
* TheEvilsOfFreeWill: They genuinely believe that they are bettering the lot of other species by trying to absorb them.
* {{Expy}}: Ever since the Borg were first introduced, ''Series/DoctorWho'' fans have been accusing them of being a copy of the Cybermen from that series (creepy collectivist originally-humanoid cyborgs who forcibly convert and assimilate other species). The accusation then got reversed after the 2013 ''Doctor Who'' episode "Nightmare In Silver" gave the Cybermen abilities that had never previously been associated with them, but looked a lot like the Borgs' (such as instant assimilation via nanotech, and the ability to rapidly develop immunity to attacks and share it among themselves).
* HiveMind: Although each drone makes up part of a collective whole...
** MindHive: ...the individuality of each drone is overwhelmed by the personalities of a thousand others.
** HiveQueen: The Borg Queen, who claims to personify the Collective rather than lead it. The characters aren't quite sure how this works either.
* HordeOfAlienLocusts: Unlike the eco-conscious Federation, Borg tech isn't terribly dolphin safe. We see a brief glimpse of a post-Borg Earth in ''StarTrekFirstContact'', and [[GaiasLament it's not pretty]].
* ImplacableMan: Part of what makes them so scary is that once they've adapted to your weapons, even the lowliest drone is virtually unstoppable.
* TheJuggernaut: You may be able to pick a few off, but the collective a whole will eventually adapt and keep relentlessly coming until they overwhelm you.
* KnightOfCerebus: A case could be made for the discovery of the Borg changing the tenor of the entire franchise. Before they were discovered, the Federation was in a state of peace not unlike the ''Pax Romana''. Local threats like the Romulans and Cardassians were matched by Starfleet, and there was a general sense that they were ready for anything. After the devastating and devastatingly short conflict in "The Best of Both Worlds," the Federation came to realize how complacent they'd become, and the repercussions would echo throughout ''TNG'', ''[=DS9=]'' and ''VOY''.
** Here's one species whom Captain Picard absolutely ''can not'' negotiate or reason with. He might as well be lecturing at a brick wall.
-->'''Borg Cube, speaking as one:''' [[foldercontrol]]

[[folder: We wish to improve ourselves. We will add your biological and technological distinctiveness to our own. Your culture will adapt to service ours. ]]
'''Picard''': Impossible! My culture is based on freedom and self-determination!\\
'''Borg''': [[/folder]]

[[folder: Freedom is irrelevant. Self-determination is irrelevant. You must comply. ]]

* LogicBomb: In ''The Next Generation'', a proposed weapon against the Borg was to send them a geometric figure, the analysis of which could never be completed, and which would, therefore, eat more and more processing power until the entire Borg hive mind crashed. Obviously the Borg don't use floating point numbers.
* LogicalWeakness: Cubes have no visible weak points: no engines, gun turrets, sensors, shield projectors, or any components at all that are identifiable out of the morass of ductwork and pipes. There are some unique components such as nodes that connect the ship and its crew to the greater Collective, but they're invisible from the outside and resistant to scanners. Cubes are also optimized to engage in combat from any direction, as any side can act as a weapons battery.
* MadLibsCatchphrase "I am X of Borg. Y is irrelevant. {{You will be assimilated}}. {{Resistance is futile}}."
* {{Mordor}}: The Borg have their own version of Utopia Planitia, dubbed the "Unimatrix", where hundreds of Borg cubes link up to form a massive, geometric city. The Collective has several of these installations all over the Delta Quadrant, but the most sizable one is Unimatrix 01, where the Queen hangs out (along with trillions of drones).
* MultipleChoicePast: ''Voyager'' hinted that the Borg were originally a benign "Cooperative", using nanotech and brain interfacing to improve the lives of its people. Eventually, they lost sight of their principles and devolved into an all-consuming Collective (a la the Soviet Union).
** Early fanon speculated that [[Film/StarTrekTheMotionPicture V'Ger]] was masterminding the Borg. The extra section of the game ''Star Trek: Legacy'' contains the "Origin of the Borg", which tells the story of V'ger declaring all carbon-based life an infestation of its creator's universe (unaware of the existence of non-mechanical intelligent life, including the humans who built it).
** In the graphic novel ''Star Trek: The Manga'', the Borg resulted from experimental medicine gone wrong. An alien species facing extinction created {{Walking Transplant}}s and then stored them in space. Over time, the medical facility deteriorates and so too does the programming of the nanomachines. The nanomachines begins infusing themselves into the patients, interpreting them as parts of the satellite in need of repair. Among the patients is the daughter of the head medical researcher of the satellite, later to become the Queen.
** In the novel ''Lost Souls'' (the third book in the ''Star Trek: Destiny'' trilogy) the Borg aren't evil because of their cybernetic nature or Hive Mind, but because the first assimilation process went horribly wrong, and subordinated the will of its drones to an Elder God-like alien whose mind had entirely faded away, save for an all-consuming hunger.
* TheNeedless: Borg don't eat and they don't require sleep, although they do need to 'regenerate' in alcoves to refill on energy. Alcoves are packed together and stand vertically to save on space.
* NoodleImplements & SwissArmyWeapon: Since "Best of Both Worlds" it's become a staple for Borg drones to menacingly point an arm while flexing various hooks, pincers, and can openers.
* OurVampiresAreDifferent\OurZombiesAreDifferent: Early Borg designs were more like vampires than anything else, given that they produce "bite marks" on the necks of their victims (from the assimilation tubules) and all short out if the "head vampire" (the Queen) is killed. This was before the Borg's appearance was changed from chalk-white (like a vampire) to looking discolored and gross (like a rotting zombie).
** Lily in ''First Contact'' referred to the borg as "[[NinjaPirateZombieRobot Bionic Zombies"]], and B'elanna Torres in ''Voyager'' equated the collective as a whole to an [[HordeOfAlienLocusts insect colony]].
* OutsideContextVillain: In "Q Who" it took the ''Enterprise'' crew the entire episode to realize just how hilariously outgunned they were compared to a single Borg Cube.
* RedEyesTakeWarning: The iconic Borg eyepieces always contain laser sights.
* RealLifeWritesThePlot: The Borg were originally conceived as being more insectoid than anything else. When budgetary restraints dictated that they be played by humans in costume, a different way to make them scary and "inhuman" was needed, so the writers settled on cybernetics and zombie-like behavior, though the Collective as a whole still captures an insectoid vibe.
* RogueDrone: Hugh (rendered from "You") the Borg from the ''Next Generation''. Although he initially follows standard Drone behavior, his separation from the Collective causes him to take a liking to Picard's crew and develop a sense of individuality.
** Seven of Nine from ''Voyager'' is the most famous example. Her full designation is 'Seven of Nine, Tertiary Adjunct of Unimatrix Zero-One'. She came forward as an Emissary when ''Voyager'' was obliged to form an alliance with the Borg, only to backstab them at the earliest opportunity. Once her link to the collective is severed, she struggles with her rediscovered humanity.
** "Unimatrix Zero" is a subcollective of drones who retain their individuality and can interface while in stasis. They are eventually freed from collective control and start a civil war within the Borg.
* ScaryDogmaticAliens: At one point in ''[=TNG=]'', Picard's crew debates whether or not they're in a state of war with the Borg. War was never formally declared, but Troi points out that it's only because the Borg don't bother with diplomatic niceties like that.
* SinisterGeometry: The Borg cube and sphere. Cubes are exactly that, a maze of redundant systems with no individual piece standing out from than the whole; if a Borg ship is 78% damaged it can continue to function effectively. They're also '''HUGE''' (roughly the mass of Manhattan and [=12x=] times bigger than a ''Galaxy'' class), and [[LightningBruiser able to overtake the Enterprise at Warp 9.]] Word of God stated that the "indifference" of the Borg cube is what makes it so scary. Spheres appear to be the Borg equivalent of fighters. There's also the rarely-seen hexagon freighter (fried in a solar flare by Dr. Crusher in "Descent", and seen again in "Dark Frontier") and the Queen's Yacht, which is diamond shaped (also seen in "Dark Frontier").
** Gene Roddenberry originally intended for the Borg to only use spheres, since it can be mathematically proven that a sphere is the most efficient shape (in the sense that no other shape with the same surface area will have as great an interior volume). However, spheres were too hard for the special effects people to produce so he was forced to use cubes instead.
* WasOnceAMan: We see former humans, Romulans, Klingons, and even Bolians amongst their ranks.
** In ''Star Trek Online'', the universe is at the mercy of [[FluffyTheTerrible Borg Tribbles]]. They have comparatively-low IQ and emit dialup tones.
* VillainCred: "Don't! Provoke! The BORG!" ...Said the member of the Q continuum.
* VillainWorld: The Borg managed to conquer Earth in a possible BadFuture. It is teeming with nine billion Borg, with copper-colored waters, metallic soil, and bridges stretching over the sea like cobwebs. (''StarTrekFirstContact'')
* TheVirus: Upon assimilation, the subject [[BaldOfEvil loses all of their hair]], sprouts TaintedVeins (from the nanomachines clogging up their arteries), and develops an ashen, moldy skin coloration.
* WetwareBody: By the time the nanites reach your brain, you are, for all intents and purposes, controlled by the Collective's CPU. Eventually some drones will retrieve you and prepare your body for Borg enhancements. However, you can still do a lot of damage without them.
* UtopiaJustifiesTheMeans: Their ultimate goal is the attainment of 'perfection' through the forced assimilation of diverse sentient species, technologies, and knowledge.
-->"Why do you resist? We only wish to raise quality of life, for all species."
* VoiceOfTheLegion: They actually do tend to talk in unison - an individual drone only has a slight 'electronic' edge to their voice.
* XMeetsY: The Borg could be seen as a middle-ground between [[CyberneticsEatYourSoul Cy]][[UnwillingRoboticisation borgs]] and [[ZombieApocalypse Zom]][[EverythingsDeaderWithZombies bies]]. The fact that they combine two of the most popular examples of UncannyValley likely accounts for both their popularity and the [[NightmareFuel terror they induce]].
* YouHaveNoChanceToSurvive: A pointed out by {{SFDebris}}, the Borg standard hail isn't a threat. It's a verbal equivalent of a wrecking ball. Your species has been selected for assimilation, and that's the end of it. Might as well make it easy on yourself and not try to resist.
* YoureNothingWithoutYourPhlebotinum: While the Borg have acquired vast stores of knowledge from civilizations they have assimilated, they seem to have lost the ability to innovate. They now learn solely by assimilating knowledge from other races, doing no research or inventing of their own. This proved to be a devastating disadvantage when they faced a species that resisted their assimilation technology.
** Ex-drones have a hideously difficult time adapting to life outside of the Collective, as Seven of Nine demonstrated. Hugh was released back into the wild after being unplugged, with the hope being that he would enlighten them. Instead they formed a brand new Collective (under guidance of the manipulative Lore), even forcibly recruiting others into it.
** The level of difficulty seems to stem mostly from the age and development of the individual prior to assimilation. Most individuals that were assimilated as adults generally regain their individuality fairly quickly, aside from a severe case of PTSD. Picard regained his original personality almost immediately, being fit for duty within a couple of weeks (although Starfleet relegated Picard to duties away from fighting the Borg the next time the collective invaded), and several other examples exist in Voyager. The reason that Seven has such an issue is because she was assimilated as a child and essentially never had a childhood, as the Borg artificially accelerate assimilated children to maturity. The group formed by Lore could have been a CultColony that had nothing to do with the Borg, that was only done so they could include Hugh back into the story.
* ZombieGait: While not zombies as such, the Borg play by many of the rules of zombies, including continuing to plod slowly no matter how many of them get shot, and never using weapons other than their Assimilation Tubes of Doom.
** Averted in the Elite Force games, in which the Borg attack without provocation, move much more quickly, and actually fire their arm cannons. Granted the Borg only fire weapons in this scenario because they are trapped in the same situation Voyager is in, lost a good chunk of their cube to harvesters, and are up against the harvesters as well as Species 8472, two species that cannot be assimilated. The Borg are actually playing their characterization straight, as they adapt to the situation.

->''"He's king of his particular hill, Commander. You'll have to treat him that way."''

Pudgy, taciturn little men in mustard-colored uniforms. For nine millenia, they have been regarded as having the most brilliant strategic minds in the galaxy. (Because of this perception, [[InformedAbility no one has ''tested'' the Zakdorn in combat]]. Hmm.) As a result, the Zakdorn are replete with self-assuredness and overconfidence; on the few occasions the ''Enterprise'' invited them aboard, they invariably start barking out orders as if they own the place.
* FatBastard
* InsufferableGenius
* SmallNameBigEgo: Picard wryly remarks that brinkmanship is sometimes more important in war than actually fighting, something the Zakdorn are experts at. This prompts Worf to dismissively note that their "reputation means nothing."

-->''"The sentence is death; [[KangarooCourt let the trial begin]]."''

The Cardassians embody the lizard brain: merciless, conniving, and xenophobic. Their society is depicted as being [[KafkaKomedy Kafkaesque]], with criminal trials where the defendant is presumed guilty and the sentence is already decided before the trial begins. In Cardassian mystery novels, [[EverybodyDidIt everyone is always guilty]], the puzzle to work out being who is guilty of what. Their public face is one of genteel politeness, but they are dangerously smart and underestimating them is foolish.

* AffablyEvil: The Cardassians aren't thugs like the Klingons, or ice-blooded professionals like the Romulans, or even brutal logicians like the Borg. These are people who can carry on an intelligent conversation and are ''deeply'' interested in charming you... so they can insert a knife later.
** Even if they genuinely consider you a friend, it doesn't make them any less dangerous. A Romulan will stab you in the back, and if you ask why, will smirk haughtily and say "For the Glory of Romulus" or something to that effect. A Cardassian will stab you in the back...[[ApologeticAttacker then apologize profusely]]. If you ask ''them'' why they did it, they'll look at you funny and earnestly reply, "[[BlueAndOrangeMorality ...Because it needed stabbing, obviously?]]"
* AlwaysNeedWhatYouGaveUp: The Cardassians are, naturally, chagrined at the discovery of a stable wormhole in Bajoran space... ''after'' they have already pulled out from Bajor. They're constantly waiting to swoop back in and take it. (All under the guise of [[BadSamaritan helping the new Commander find his sea legs]], of course.)
* ArmiesAreEvil: The military, led by Gul Dukat, extended an olive branch to the Dominion in exchange for their share of the Alpha Quadrant once it was conquered. This didn't work out so well.
* BecameTheirOwnAntithesis: In the end, the Cardassians were forced to become this: guerrillas fighters struggling to take back their planet.
* BelligerentSexualTension: The females of their species are turned on by argumentative males. O'Brien learns this the hard way after getting into a spat with a Cardassian engineer. ("I'm ''very'' fertile.")
* BigBrotherIsWatching: It was said that the average Cardassian could not sit down to dinner without the contents of the meal being noted and logged by the Order.
* BreadAndCircuses: Televised treason trials are constant and serve as the planet's most-watched form of entertainment. The proceedings are crafted to maximize drama and schedenfreude, such as prodding the weeping families of the accused [[IHaveNoSon to renounce their husbands/fathers/sons]] and testify against them, to discouraging private conferences between consul (which the viewing audience can't overhear). Odo exploited this flaw in the system by staging continual {{Courtroom Antic}}s until the Arcon (Judge) finally got sick of him and the case and released Chief O'Brien rather than be further humiliated on live TV.
* CannedOrdersOverLoudspeaker: Exterior shots of Cardassian-Prime always include a giant Jumbotron barking out slogans to the populace.
* ComplexityAddiction: This is evident in battle, as evidenced in "Soldiers of the Empire" in which a Klingon speaks admiringly of Cardassian adversaries who always had "[[XanatosGambit a plan within a plan within a plan leading to a trap]]". A popular Cardassian board game is Kotra, which, as Garak describes it, favors bold tactical maneuvers over defensive play; hence his annoyance at a Ferengi's attempts to stockpile his 'assets' during their match.
* DeadlyGraduation: Within the Obsidian Order, at any rate, having to torture a loved one or close acquaintance is used as a test of loyalty for NewMeat recruits. Blegh.
* DumbIsGood: They are meticulous record keepers, even training other worlds on the art of bookkeeping. Like most imperial powers, their art and sciences are second to none. Finally, the Cardassians themselves all have photographic memories, which means you can't even trust them glancing at your tech.
* EvilAlbino: Some Cardassians are a reptilian green, a trait seemingly common to the solider class; others are a chalky white.
* EvilCannotComprehendGood: Cardassian literature often confounds humans, and vice versa. Garak complains that any fool can figure out during the first act of Creator/{{Shakespeare}}'s ''Theatre/JuliusCaesar'' that Brutus is going to betray him, and cannot understand why Caesar doesn't figure this out (or is willfully blind to an impending coup d'état) until the knives are literally coming at him from all directions. Likewise, most AgathaChristie novels cause Cardassians great difficulty; whilst the idea of a VIP being killed under mysterious circumstances appeals, they can't grasp how one person carried out the deed without any help.
* EvilIsDeathlyCold: Inverted; Cardassia is a humid planet. The cold-blooded denizens prefer warm climates and dimmed lighting. What humans consider to be room temperature is frigid to a Cardassian.
* EvilVirtues: Cardassian culture is fervently patriotic, and while the ugly facist side of that all-consuming fixation on dutiful obedience is frequently noted, their [[StiffUpperLip willingness to endure misery and misfortune]] in the name of duty is often admired.
* EvilVsEvil & AHouseDivided: Cardassia operates under a tripartite system of the civilian government (Detapa Council) the ruling junta (Central Command) and the intelligence service (Obsidian Order); in practice however, the Counsel was completely toothless and allowed the other two to operate in complete autonomy. There has always been friction between Central Command and the Obsidian Order as their mission statements didn't gel; the former worked to expand Cardassia's borders, and the latter fought to insulate them. This power-sharing agreement finally came to an end when the Order launched a botched attack on the Changelings' homeworld in the Omarion Nebula without permission from the military. This failure allowed the Central Command to disband the Order, but at the cost of crippling Cardassian security. This resulted in the dissident movement gaining significant ground and restoring the authority of the Detapa Council. For a time the government was concerned mostly with putting down riots all over the planet.
* {{Family Values Villain}}s: ''In theory.'' Cardassian culture is for the most part a deeply nurturing and family-oriented culture, but there are many [[SelfMadeOrphan ugly exceptions]] [[OffingTheOffspring to the rule.]]
-->'''Picard:''' When children are taught to devalue others, they learn to devalue everything else. Including their parents.
* FantasticRacism: Dubbed "Cardies" and "Spoonheads" by veterans of the Cardassian-Federation war. The Cardassian government clearly had a much worse racism against Bajorans, tormenting them in huge numbers in Holocaust-type death camps.
* FalseReassurance: Cardassian jurists are more like father confessors. The Judge presiding over the Miles O'Brien case assured his Captain that the Chief was enjoying "the most efficient criminal investigation system in the quadrant" and "the best counsel in all Cardassia." Sounds great, but run it through the Newspeak translator and you soon discover what Cardassian "efficiency" really means. ("Tribunal")
-->'''O'Brien:''' Have you ''ever'' won a case?\\
'''Public Conservator:''' Winning isn't everything!
* GenerationalSaga / PatrioticFervor: One of their most revered forms of literature is the repetitive epic, which traces a family throughout history, focusing on each generation's virtually identical allegiance to the state. Dr. Bashir finds it dull as dishwater.
* GoodHairEvilHair: A good Cardassian never has a single hair out of place.
** SlipknotPonytail: The standard Cardassian hairstyle is severely slicked back and shiny, to compliment their reptilian features and metallic uniforms. Whenever a Cardassian gets their hair out of order, it's a sign that sh!t just got serious.
* HobbesWasRight: Cardassia was originally a peaceful, spiritual planet not unlike Bajor. A mass famine resulted in the junta we see today.
* HollywoodAtheist: Most of Cardassia's finest religious artifacts were sold in order to beef up the military. Symbolically, this represented the Cardassians (then-known as "Hebitians") exchanging their old faith for a quasi-fanatical nationalism.
* IntertwinedFingers: Touching palms is the equivalent of a kiss on the cheek.
* KangarooCourt: Court proceedings work in reverse on Cardassia. Sentencing is determined from the start, and then a sham trial is conducted on live TV for the purposes of celebrating "the wisdom of the state" -- hence why the most illustrious defense attorney on Cardassia has a win/loss record like [[PunchOut Glass Joe's]]. A defense lawyer who actually wins a case, even by accident, is executed for ''not doing their job poorly enough''.
* LaserGuidedKarma: The Dominion came with promises of extending Cardassia's power. However, they ended up consuming their resources, causing their territory to ''shrink'', and occupied their homeworld with various Dominion-affiliated species.
** When Damar led a resistance group against their "allies", the Dominion retaliated by implementing a scorched earth-policy on Cardassia-Prime. Luckily, the Founder in charge was taken into custody before she could kill them all. However, the ruination of their home planet set Cardassian culture back a hundred years -- just as the Cardassian occupation had set back the Bajorans. Also, the Cardassian Union is completely smashed and Garak no longer recognizes his homeworld. It's interesting the words he uses: He declares that Cardassia is "guilty as charged." For a species obsessed with law and order, turning such a loaded term on his own government is a [[HeelRealization huge paradigm shift]].
* LizardFolk
* MeetTheNewBoss: They could be also considered a refinement of the Romulan menace on TNG, as they were introduced just as Sela and her cohorts were phased out. (Funnily enough, the Cardassian Elim Garak, no stranger to magnificent bastardry himelf, threw shade on the entire Romulan race in "Inter Arma Enim Silent Leges".)
** The Cardassians really are to the nineties what the Klingons and Romulans were to the sixties: While Gene's generation were scared of a monolithic 'other' threatening atomic annihilation, the nineties brought the fear of government surveillance, false flag operations and political upheaval.
* MenAreUncultured: Similar to the Romulans, the Cardassians don't discriminate based on gender. However, there is some shoehorning regarding their vocation: men are expected to enlist in the military, leaving the sciences and engineering fields to the women. While we see no evidence of Cardassian men being inferior in these areas, it has given rise to a bias that men [[DoomItYourself can't even replace a spark plug]] without help.
* ANaziByAnyOtherName: The ethics of using Nazi science are discussed in "Nothing Human" (VOY), in which the Doctor revives a Mengele-type from the Bajoran Occupation as a hologram. Naturally, the Cardassian scientist is all honey when chatting about his work. Eventually the Doctor deletes the hologram when the subject's horrors come to light.
-->'''Doctor:''' Are we also going to tell them ''where'' you honed your surgical techniques? A footnote, perhaps. "For further details, see: Cardassian death camps."
* PeoplesRepublicOfTyranny: Their official moniker, the Cardassion "Union", is emblematic of Cardassian blancmange. They were originally called the Cardassian Empire, but this was changed much later on, presumably to differentiate them from the Klingon and Romulan Empires. It's also useful for deflecting accusations of colonialism. (We're all in this together!)
* PoliceState: It was boasted that even the poorest Cardassian citizen could walk the streets without fear... of the ''civilian'' population, that is.
* PsychicBlockDefense: The Obsidian Order's agent training program is so advanced that they are made immune to most forms of interrogation, including Vulcan mind melds.
* TheQuisling: Cardassia was the first Alpha Quadrant power to sign on with the Dominion, in direct opposition to the Federation.
* ReptilesAreAbhorrent: They are reputed to display pack-like behavior, desiring to establish -- or at least determine -- dominance in any social situation. They're also self-confessed xenophobes.
* SaltTheEarth: The Changelings and Vorta tried to glass Cardassia-Prime in retaliation for an uprising against them.
* TheSocialDarwinist: In addition to invading weaker worlds to 'civilize' them, Cardassians regularly pick each other off, too, seeing no need to preserve that which is no longer useful.
* TheSpartanWay: Cardassians favor tough-minded pragmatism over the kinder emotions. Dukat once declared, "Education is power, joy is vulnerability", the Cardassian credo for raising one's children. A dissenting position is taken by Gul Ghemor, who regretted seeing his artistic-minded daughter abandon her sculptures to join an intelligence outfit, and mused that Cardassia "could use more artists."
* SecretPolice: Cardassia-Prime has its own flavor of the Tal Shiar, the "Obsidian Order."
* TakeUpMySword: Another heartwarming Cardassian family tradition. On his deathbed, the father uses his [[LastRequest dying breaths]] to read a list of names. It falls to the eldest son to ensure daddy's enemies don't go unpunished.
** The ''Shri-tal'' is normally read to family members, but there are exceptions: Legate Ghemor told his secrets to Kira Nerys, whom he considered a surrogate daughter, even though she was Bajoran. ("Ties of Blood and Water") Garak also allowed a human, Dr. Bashir, to be present during his father's dying breaths, although his father had gone blind and assumed that they were alone.
* TertiarySexualCharacteristics: The females have telltale blue marks on their foreheads and neck ridges. Their lips are also a darker hue.
* ThisMeansWar: The Dominion destroys a major population center, Lakarian City, to [[MakeAnExampleOfThem set an example]] for any other would-be heroes who might support the revolution. This act of cowardice causes the Cardassian ships to break from the rest of the fleet and turn their guns on the Founders.
* TortureFirstAskQuestionsLater: Torture is so ubiquitous in the C.U. that it's practically a cultural custom. If a prisoner is said to be "well-treated", you can bet that unfortunate person is getting the full treatment, all right. Cardassians are known to enjoy torturing their prisoners whether there is information to be extracted or not. For instance, the Orwellian "Bureau of Identification" has the bland task of keeping dental records of all Cardassians, usually by Age 10. ''Non''-Cardassians who commit crimes in their space are also required [[TheToothHurts to hand over a molar]]. This is akin to being tortured by the DMV.
** In a nice Terry Gilliam touch, we even see a TortureTechnician inviting his young daughter into the chamber in a sick parody of Take Your Child To Work Day.
* WeComeInPeaceShootToKill: Initially, the peace-loving Bajorans welcomed their Cardassian visitors. The Cardassians repaid their hospitality by occupying Bajor for fifty years, during which time they forced many Bajorans into slave labor, using them in their various mining operations.
* WickedCultured: The Cardassian education system is top-of-the-line, even by Federation standards. They seem to produce Magnificent Bastards at an unusually high rate.
** Boasting about one's education and intellectual prowess is considered a form of flirting among Cardassians.
** It's worth noting that their theme music in ''Star Trek Online'', a bombastic "Battle Suite", includes a [[ClassicalMusic harpsichord]] as one of the instruments.
* WitchHunt: When Picard spoke of the "drumhead trials" in Earth's past, he might well have been describing Cardassia's legal system. Fake charges have been known to happen (in fact we never see or hear of ''legitimate'' charges), but that doesn't matter because there is only one verdict on Cardassia, and that verdict is always the same.
-->"Whatever you've done, whatever the charges against you, none of that really matters in the long run... This trial is [[MakeAnExampleOfThem to demonstrate the futility of behavior contrary to good order]]."
* WrenchWench: The females of the species appear to have a natural aptitude for machinery and coding. The EMH even encountered a holographic Cardassian who could repair her own program and was entirely self-taught.
* YouTalkTooMuch: Conversation might just be the best tool in their arsenal, as even the planet's head spymaster agreed. Most Cardassians love the sound of their own voice. As a downside, they find silence most unsettling. (Garak once broke a man by mutely staring at him.)

-->''"Such a deeply spiritual culture. [[GoodIsBoring But they make a dreadful ale]]. Don't ever trust an ale from a god-fearing people."''

The [[TheTroubles IRA]] [[/folder]]

[[folder: in space! ]]
, the Bajorans suffered under the heel of the Cardassians for fifty years. A resistance movement drove off their oppressors, and now the planet is struggling between freedom, religious dogma, and order. The Federation could not intervene in the Cardassion occupation, due to Prime Directive considerations; as such, the Bajorans are in no hurry to become a Federation member. Similar to the Trills, the Bajorans' makeup was the result of a injunction by Rick Berman against [[RuleOfSexy marring the beauty of Michelle Forbes]]. It also simplified the task of filming an entire crowd of Bajorans at once.

* AlternateUniverseReedRichardsIsAwesome: In the Mirror Universe, these guys are actually handing out assignments to the Klingons ''and'' the Cardassians, and have the Terran Empire on the run. In another reality ("Parallels"), the Bajorans have essentially swapped places with the Cardassians (complete with a Cardassian at Ro Laren's bridge station) and had powerful warships.
* ArtShift: A rare [[LiveActionTV Live-Action]] example. In their first appearances, the Bajorans' trademark ridged nose was augmented by a triangular almost-[[RubberForeheadAlien Rubber Forehead]] (Note Ro Laren above). This was present throughout ''TNG'' and the first season of ''[=DS9=]'' before being eliminated.
** The exact shape of their Nose Ridges changes, as well. Both from person to person and for individual Bajorans (ESPECIALLY Kira).
* BizarreAlienBiology: During pregnancy, Bajoran women suffer from uncontrollable bouts of ''sneezing'' (rather than morning sickness). The delivery itself is a tantric experience, with relaxing incense and chimes.
** The Bajoran heart features a horizontal cardiac axis, unlike the Human heart, which has a vertical axis.
* EarlyInstallmentWeirdness: Bajor was first introduced on TNG, where it was always referred to as "Bajora" with the extra letter at the end.
* ExpressDelivery: Vascularization between a Bajoran fetus and the mother is extremely high. Bajoran women carry their babies for only five months.
* FanserviceWithASmile: Quark's Dabo girls. Not all Bajoran women are nuns, after all. (Interestingly, even these scantily-clad bombshells are quite religious in private.)
* FantasticCasteSystem: Bajoran society ''used'' to have a strictly divided caste system (called a "D'jarra") which dictated one's profession. The castes were inherited through families and it was impossible to switch out of the caste you were born in. During the Cardassian occupation, the caste system was abandoned so that everyone could devote themselves to the task of fighting off the Cardassians, and the Bajorans did not return to the system after the occupation ended (at the beginning of DS9). The Occupation lasted over 50 years, so the caste system hasn't been in place for half a century - this extends to the point that virtually ''all'' Bajorans (most of whom grew up after the caste system was abandoned) just consider it a historical artifact with absolutely no bearing on their lives (sort of like how someone with the last name "Smith" doesn't even frequently think that one of their ancestors was probably a blacksmith). Even the religious clergy of the Bajorans make no attempt to re-institute the caste system. It has so little bearing on the lives of modern Bajorans that only one episode even ''mentioned'' the former caste system, though it featured as the main plot...
** One episode has a time-traveling Bajoran, claiming to be the Emissary, try to restore the caste system, which would have cost Bajor its chance at Federation membership. Sisko, despite his [[StopWorshippingMe reluctance]] to fulfill the MessianicArchetype he had been previously bestowed, eventually challenged the time-traveller for the Emissary title after caste-based discrimination led to violence on the station. We learn that Kira is actually a member of the artisan-caste, forbidden to serve as military officers, so she (temporarily) has to leave her post and take up sculpting (and she's really bad at it).
* HufflepuffHouse: There is still some resentment toward the Federation over their handling of the occupation (or lack therof). In 2369, when Commander (later Captain) Benjamin Sisko was assigned command of [=DS9=], one of his main tasks was to groom Bajor for official membership with the Federation. However, Sisko, acting as Emissary of the Prophets, realized that if Bajor were to join at that time, it would be destroyed by the Federation's many enemies; heeding his warning, Bajor chose to remain neutral.
** According to the StarTrekNovelVerse, Bajor finally formally joined the Federation in 2376, the year after the Dominion War ended. The Bajoran Militia was absorbed into Starfleet.
* IconicItem: Their earrings, which serve as a coat of arms for their families (a leftover from the old Bajoran caste system?). It is also a symbol of their faith: a Bajoran cleric could gain information about a person's "pagh," or aura, by holding onto their left ear.
* LaResistance: Most major Bajoran characters were part of it. The others were members of the clergy.
* LadyLand: Bajor has some shades of this. Their only-functioning military arm, the Bajoran militia, is still predominantly male. However, it's a female Kai who calls the shots. (Men are free to run in the papal election, but we never see one win.)
** Bajoran woman are also noted for being tough cookies; O'Brien's first question to Sisko when he stepped onboard the station was if he'd ever served with one, cautiously referring to the furious Kira in the upstairs office.
*** Also Ro Laren.
* LastNameBasis: Bajoran tradition places the family name before the given name, in the Asian style.
* [[OccupiersOutOfOurCountry Occupiers Off of Our Planet]]: They were this to the Cardassians during the occupation.
* ReligiousBruiser: At times. Though their lack of power means they spend more time getting bruised then bruising.
** It's insinuated that under different circumstances, the Bajorans could be just as aggressive and threatening as the Cardassians.
* TheRevolutionWillNotBeBureaucratized: Once the Cardassians finally packed up and left, the Bajorans began to show every indication of sliding back into superstition, caste lines, and tribal warfare. Starfleet deploys Ben Sisko and a small platoon to keep the peace, but adding ''more'' bureaucracy is hardly what the Bajorans want.
* TheRevolutionWillNotBeCivilized: When they get worked up, they really don't care who pays for another's crime.
* SkeletonGovernment: The Provisional Government was set up after the occupation ended. Most people expect it to implode right away, leading to firing squads and civil war. Luckily, that didn't happen, but the Kai (a cross between the Pope and, well, planet-wide regent) is still the de facto ruler of the planet. Let's hope a total megalomaniac doesn't get herself elected ...[[OhCrap wait]].
** A three-part [=DS9=] episode, 'Homecoming', 'The Circle', and 'The Siege', featured a story arc about the Provisional Government and its inability to defuse an explosive political revolution.
** By about Season 5, the Provisional Government seems to have been replaced with a standing government known as the Council of Ministers.
* SpaceElves: Subverted. While they are mystically minded they don't have an OurElvesAreBetter air to them. However, the Bajorans are a ''very'' religious people, and can get pretty haughty about anything that doesn't quite gel with their beliefs.
* SpaceJews: Although the writers for [=DS9=] stated that the Bajorans were modeled after any number of oppressed cultures throughout the ages, they do have a lot of parallels with Jewish history. For one, they have one of the oldest civilizations in the Alpha Quadrant; there's also that bit about managing to reclaim their spiritual homeland after centuries of languishing under foreign domination.

->''"Every new life for a Trill has to be a new life. If not, you wind up paying off old debts forever."''

Trills have evolved to coexist with an ageless alien slug (known as a symbiont) in their abdomen. Ordinary Trills are weak, standard humanoids; when "joined", however, they gain the knowledge and experience of the symbiont's previous hosts. Left to their own devices, the symbionts are an endangered species, living out a dull existence in underground pools. The Trills sported a [[RubberForeheadAliens rubber forehead]] on TNG, but makeup artist Micheal Westmore unashamedly changed their look when Terry Farrell was cast as one. Westmore then suggested, "meh, just give her spots like we gave [[FamkeJanssen Famke]]", and the rest is history.

* BizarreAlienBiology: They are noted for their cold hands, for some reason. This is probably the least bizarre thing about them.
** The brain of a joined Trill has two cerebral nuclei and two brain wave patterns. Dr. Bashir compared them with two linked computers, which both work for the same task.
* BondCreatures
* CantLiveWithoutYou: Ninety-three hours after the joining, the host and symbiont are completely interdependent, but once that threshold is passed, the joining can't be reversed without killing the host. Worse yet, an unjoined Trill will [[FreakOut suffer a panic attack]] at losing all of their memories and talents.
** Likewise, the symbiont will also die unless returned to their habitat (pools of nutrient-rich milk on the Trill homeworld) or rejoined within 48 hours.
* FantasticCasteSystem: The joined have more prestige then the unjoined.
* TheHedonist: A largely positive example. As part of their contribution to their symbiont's massive library of experiences, Trill hosts are encouraged to indulge in just about every pleasure under the sun(s).
* HeroicHost: The Dax symbiont helped negotiate the Khitomer accords, and even (gulp) dated Bones [=McCoy=] in medical school.
* HumanoidAliens: The only outside difference is the leopard-like spots on the neck.
* ImmortalityBisexuality: Dax has been married six times: Four times as the bride, and twice as the groom. In one episode, Jadzia Dax bucks the system and kisses her former spouse, who happens to be a lady. Odam tried to put the moves on Dr. Crusher once his symbiont was transplanted into a woman, but, being as this aired in 1991, she emphatically said no.
* KangarooPouchRide: The symbionts are surginally inserted through a slit in their host's abdomen.
* LiteralSplitPersonality: The ''zhian'tara'' is the Trill answer to the Vulcans' katra. It allows joined Trill to convene with their previous hosts for a day. During the rite, the personalities of the old hosts are telepathically implanted into willing participants (usually loved ones or friends) by an employee of the Symbiosis Commission. ("Facets")
* LivingForeverIsAwesome: Joined Trills have a big legacy to live up to. With that in mind, the most important quality looked for in candidates (after high intelligence and aptitude in their chosen field) seems to be a ''bon vivant'' personalty that has a good chance to nurture a noted scientist, artist, or politician.
* TheMasquerade: It was originally guessed that only a small fraction (0.01%) of the Trill population was suitable for being joined, a myth that the Trill government continues to perpetuate, lest the symbionts become a commodity to be bought, sold and fought over. As long as it is widely believed that only the chosen few can become hosts, the government reasons, such piracy can be avoided.
* NoBiochemicalBarriers: Averted just this one time. In rare cases, symbionts can be joined with non-Trills, but the differences in biology means this is only a stop-gap. ("The Host", TNG) Commander Riker was briefly joined to the Odan symbiont so that Odan could complete peace negotiations, and to keep Odan alive until a replacement host arrived. While this ordeal saved Odan's life, it nearly killed Riker.
* ReallySevenHundredYearsOld: The symbionts. The humanoid Trill have a lifespan close to humans'.
* WeaksauceWeakness: Trill are strongly allergic to insect bites, because the toxins interfere with the biochemical reactions between host and symbiont ("The Siege", [=DS9=]).
* YoureNothingWithoutYourPhlebotinum: The symbionts are helpless, slimy worms who possess the know-how of their previous hosts, but lack the important stuff, like hands.
* YourNormalIsOurTaboo: Joined Trill are forbidden to marry someone they were married to in a previous life.

!!Species debuting in ''Deep Space Nine''

-->''"How many changelings do you think are here on Earth right at this moment? What if I were to tell you that there are only ''four'' on this entire planet? Think of it. Just four of us! And [[ParanoiaFuel look at the havoc we've wrought.]]"''

Shapeshifting aliens whose default form is a gelatinous liquid. They run the Dominion and are revered as gods by their slave races, the Vorta and Jem'Hadar, who are genetically programmed to revere them. (With gods like these, who needs devils?). They spend most of their time in the "Great Link," a huge puddle of liquefied Changeling that covers the surface of their planet, but many years ago they sent out 100 individuals of their race to make contact with the "Solids" of the galaxy. AndNowYouKnow how Odo got to the Alpha Quadrant.
* AbusiveAlienParents: The Great Link launched 100 infant Changelings (including Odo and Laas) into the Alpha Quadrant to make contact with alien races. The idea was to gauge the treatment of helpless foundlings by each planet; if the Changeling was cared for, then the planet was ripe for infiltration. If the natives reacted poorly to shapeshifters in their midst, then they're bad news and should be wiped out. ([[MortonsFork Hang on...]]) The Great Link seemed unconcerned about the safety and psychological adjustment of the infants during this exercise.
* TheAgeless: Odo lived over two hundred years in a possible timeline, and looked no worse for wear. Laas far outlived his wife. It's possible that Changelings age much slower than humanoids do -- we see a Changeling infant, after all -- but the change is so imperceptible that it may as well be this trope.
* AlienSea: The Great Link resembles a reddish ocean.
* ApeShallNeverKillApe: Their highest law is that no Changeling shall ever harm another.
** They don't always follow this law faithfully. After Odo killed a fellow Changeling, the Founders afflicted him with an infection that would have killed him unless he returned to the Great Link for judgment. Also, in "The Die is Cast," [[spoiler: the Changeling posing as Lovok]] did not intervene when Garak tortured Odo. (And he also forgot to tell the Jem'hadar not to attack the shuttle that he ''gave Odo to escape in''.)
* AppropriatedAppellation: According to one Founder, "Changeling" was originally a slur used by Solids. This species adopted the name and persevered to make it evoke awe as well as fear.
* AssholeVictim: Considering their bigotry and history of genocide, every changeling that died pretty much qualifies.
* BlobMonster: Their true form is a shifting, translucent reddish ooze.
* [[BlondGuysAreEvil Blonds]] / BlondesAreEvil: With the exception of Laas, all the Changelings we see have blond hair in humanoid form. Laas had completely mastered his shape-changing abilities over two centuries, but chose not to alter his face because, unlike Odo, he did not identify with solids and saw no benefit in emulating them.
* ControlFreak: Their hat. Even Odo, Deep Space Nine's TokenHeroicOrc, has heavy tendencies towards this, bordering on SuperOCD at times. Their obsessive need for order and control is implied (and sometimes outright stated) to be a reaction to their own malleable, ever-changing physiology.
* CrapsaccharineWorld: In "The Search", the Changeling homeworld first appears to be a pleasant planet of gardens and monoliths. Covering the planet is the Great Link, a sea of liquid Changelings living in blissful physical union with each other. Later, viewers learn that the Changeling Founders are conformist, hostile to "solids", and the tyrannical leaders of the Dominion.
* DoesThisRemindYouOfAnything: The Section 31 virus which afflicts the Changeling race is reminiscent of the HIV epidemic. First, the virus is spread by the physically intimate act of linking, the closest Changeling analog to sex. Like HIV, the virus is lethal, at least until a cure is discovered in season 7. The lesions that appear on the infected Female Changeling resemble Kaposi's sarcoma, a cancer that sometimes co-occurs with AIDS. Finally, the virus is deliberately developed by Section 31, a shadow organization under the Federation government, as a means of bringing about a Changeling genocide. This strategy is reminiscent of early [[ conspiracy theories]] surrounding the origins of HIV.
* DrivenToVillainy: It's been suggested by Weyoun and others that humanoids have an intrinsic fear of shapeshiters. The maladaption of the Changelings to a hostile universe is understandable.
* DyingRace: The Changeling race is dying from a virus engineered by Section 31. [[spoiler: In the series finale, Odo returns to the Great Link to cure his people of the virus.]]
* EvilutionaryBiologist: They either created or heavily modified the Vorta and Jem'hadar to do the heavy lifting for them.
* FantasticRacism: They don't trust "Solids" part, because centuries ago, Solids didn't trust ''them'', and they were on the ''receiving'' end of a lot of Fantastic Racism. It left them embittered.
* FantasyAxisOfEvil: The Dominion is a living {{deconstruction}} of the Federation by Ira Behr and others. The "Big Three" races of ''Trek'' -- Humans, Vulcans, and Klingons -- are parodied and done in reverse:
** Founders: Eldritch. The Founders went out into the universe to meet new races and add to their sum total of knowledge of other species but they were [[RealityEnsues beaten, hunted, and killed]].
** Vorta: Crafty. Has pointy ears and specializes in diplomacy. Where the Vulcans are honest to a fault, Vorta thrive on deceit.
** Jem'Hadar: Savage, obviously -- Though they aren't particularly happy about it. Jem'Hadar are more well-spoken and precise than their Klingon counterparts.
** Cardassians: Fallen, once they join up.
* FreudianExcuse: The Female Changling claims that her race was abused and persecuted by solids in the past, thus they try to control solids to prevent it from happening again.
* AGodAmI: Their slave-races believe them to be such, and they're certainly in no hurry to disabuse them.
* GodKing: In the eyes of the Vorta and Jem'Hadar.
* GRatedSex: Linking.
* GuiltFreeExterminationWar: Played with. Many in the series see them this way, but there are still some who try to argue that genocide, even against the changelings, is wrong. Not that the changelings themselves have ever had any problem with genocide.
* HeWhoFightsMonsters: More ironic still, it's hinted that the changelings were only persecuted by solids after they started the whole dominion thing.
* HiveMind: The Great Link.
* JustTheFirstCitizen
* MoralMyopia/[[ItsAllAboutMe It's All About Us]]: The Changeling homeworld rivals Equestria in terms of peace and love. Yet they are ruthless in enforcing rules and boundaries on other cultures.
* ANaziByAnyOtherName: Like the Nazis, the Founders consider themselves intrinsically superior to "solids" and justify their constant border wars as a need for protection. Even, say... ''breathing room?''
* TheNeedless: They do not require food, water, or oxygen to survive. They rejuvenate naturally by reverting back to ooze for an hour or two.
** In fact, this is a key component of their servant races, too. Undoubtedly, the Founders lack an understanding of or even respect for basic humanoid desires. This was played for laughs by Ziyal (albeit unknowingly) when she gets fed up with Quark complaining about his business suffering under the Dominion.
-->'''Quark''': The Jem'Hadar don't eat, don't drink, and they don't have sex. And if that wasn't bad enough, the Founders don't eat, don't drink, and they don't have sex either. Which, between you and me, makes my financial future less than promising.\\
'''Ziyal:''' It might not be so bad. For all we know, [[{{Irony}} the Vorta could be gluttonous, alcoholic sex-maniacs.]]
* NoBiochemicalBarriers: Averted. The Section 31 virus is deadly to Changelings but harmless to humanoids. Likewise, diseases that afflict humanoids aboard Deep Space Nine do not affect Odo.
* NoBodyLeftBehind: A dead Changeling simply reverts to his liquid state or, in the case of one Founder ("The Ship"), crumble into black ash. Mirror Odo exploded into [[LudicrousGibs gibs]] when shot with a phaser.
* OneGenderRace: In their natural state, Changelings are sexless. However, some seem to prefer a masculine or feminine gender presentation while in humanoid form.
* ParanoiaGambit: A favored tactic, often seeking to provoke DividedWeFall among the Alpha Quadrant.
* PlanetOfHats: Above all else each and every blob that makes up the Changeling race loves law and order and seeks to impose them wherever they see lawlessness and chaos. For the Founders it means creating a fascist interstellar empire and controlling their subjects right down to the genetic level while for the much less morally bankrupt Odo it simply means protecting the peace of his community as a policeman (and [[SuperOCD making sure that everything in his apartment is always in exactly the right place]]). Either way, the natural instincts that drive them are the same.
* RealMenWearPink: Literally, as even the male Founders wear flowing pink garments. These are ankle-length and resemble Arabic ''thawb'' robes.
* RoyalsWhoActuallyDoSomething: They usually keep to themselves and delegate the running of the Dominion to the Vorta, but occasionally they act as spies and infiltrators.
* ScaryDogmaticAliens: Their obsessive need to impose order on everyone and the fact that they view solids the way we view rats.
* ShadowDictator: The Dominion has spent 2,000 years hiding behind a massive surveillance and military apparatus. In "Vortex", when Quark unwittingly foreshadows the Founders' paranoia of "solids" and tendency to remain hidden (either by remaining on their homeworld or secretly impersonating solids).
-->'''Quark:''' Paranoia must run in your species, Odo. Maybe that's why no one has ever seen another shapeshifter. They're all hiding!
* SpannerInTheWorks: The Wormhole, for staters. Word of God clarified that the Founders ''did'' foresee having to acquire a foothold in the Alpha Quadrant at some point, they just didn't estimate it to be so soon. The bottleneck between the Gamma Quadrant and Bajor causes them quite a few problems, enough to disrupt their usual strategy of bullying, buying off, or eradicating their neighbors ad nauseum.
* StarfishAliens: Their default form is gelatinous liquid. Furthermore, they collectively form a giant living ocean called the Great Link.
* STDImmunity: Averted with the Section 31 virus, which is spread by linking, the closest Changeling analog to sex. By season 7, the virus has spread like wildfire through the Great Link.
* SweepingAshes: What happens when you kill a Changeling. Unable to hold form, they collapse back into their gelatinous state, which in turn crumbles to coal.
* SyntheticPlague: The Section 31 virus, which quickly spreads through the Changeling population.
* TheTrickster: Played with. Their shapeshifting skills allow them to impersonate humanoids and sow discord across the quadrant. Even Laas, who is not immediately hostile, create disruptions with his shapeshifting while aboard Deep Space Nine. Despite their skill at deception and discord, their own society is largely static and conformist.
* UtopiaJustifiesTheMeans They do pretty horrible things to people that don't dance to the Dominion's tune, yet claim their victimizing in the past justifies this. In a painfully ironic example, they infected a planet with a disease designed to kill the population over ''generations'' just to make an example of them to the rest of the Gamma Quadrant. They don't see anything wrong with this.
* VoluntaryShapeshifting: Their hat. The foundlings are pretty poor at it, since they require hands-on training from others Changelings to morph. The Founders themselves can imitate pretty well anything, from wild-haired Klingons, to crystal pillars, to girderwork on a Federation ship.

-->''"What would say if I offered to make you [[OfferedTheCrown absolute ruler of the Federation?]] No President, no Starfleet Chief of Staff; just ''you."

The Vorta are genetically engineered to serve as the administrative wing of the Dominion, with the Jem'Hadar serving the military role. They also function as field commanders to the Jem'Hadar, who despise them. Despite being hatched from the same Dominion-run bioreactor tanks, the two races are as similar as night and day; Vorta are frail, scheming, and made up entirely of {{Expendable Clone}}s. (The reasoning being that Changelings are too paranoid to get acquainted with new attachés all the time)

* AssInAmbassador: They have the half-placating, half-goading attitude of somebody who's very close to royalty. Also, they're immune to almost all forms of poison, a trait the Founders implemented into their "recipe." One can only speculate how many Vorta were bumped off before they got the hint.
* BandwagonTechnique: One of the arguments they use when trying to persuade people over to the dark side- I mean, the Dominion.
* BecauseYouWereNiceToMe: The Vorta believe, perhaps apocryphally, that they previously existed as timid, ape-like aliens living in hollowed-out trees. Legend has it that one day, a family of Vorta hid a Changeling from an angry mob of "solids" that were pursuing it. In return, the Changeling promised that one day they would be transformed into powerful beings and placed at the head of a vast interstellar empire; the Founders fulfilled this promise by DNA-splicing the Vorta into humanoids (at the cost of dampening their senses, such as sight and smell) to be employed as their tools of conquest.
* BlessedWithSuck: Vorta only have a ridiculously limited sense of taste, a feature installed in their genes to remind them of their humble origins. They generally have no appreciation for art. Combine that with an intrinsic belief in the Founders as gods, bad eyesight, and zero sex life, and the Vorta might have been happier as monkeys.
* ClassyCravat & TheDandy: Vorta are the foppish eurotrash of the Gamma Quadrant.
* CloningGambit: Each Vorta has several clones on standby at all times, all of whom share their predecessor's memories. The main Vorta of the series, Weyoun, was actually the fourth one when he first appeared. He was on his eighth life when the base holding his clones was destroyed, and was finally OutOfContinues when Garak shot him in the finale.
* CyanidePill: The termination implant; they are supposed to activate it immediately upon capture, but not all do. Apparently the Founders made them a little ''too'' devious.
* DirtyCoward: One glitch in the Vorta's programming was that their self-preservation instinct outweighed other concerns. While the Jem'Hadar are trained to commit suicide should they fail, the Vorta do not; in fact, Weyoun purposely misled the Jem'Hadar into attacking a Changeling's ship rather than catch heat for an intelligence breach. ("Treachery, Faith, and the Great River") Another Vorta, Keevan, willingly sought protection with Starfleet rather than face his own men, who were stranded on a barren rock due to his ineptitude. ("Rocks and Shoal")
* DrFeelgood: A Vorta and his ever-present drug suitcase. In addition to organizing troops and waiting on the Founders, a Vorta's main job is distributing ketracel-white - the drug which ensures the loyalty of the Jem'Hadar - to his particular unit. Not the safest job in the universe.
* EeriePaleSkinnedBrunette with PurpleEyes: Every Vorta we see.
* ExpendableClone: Part of the Vorta's schtick was that they were grown as clones and had the memories of their identical predecessor imprinted on them.
* FashionableAsymmetry: Vorta wear a combination tunic/blazer which is missing a sleeve. They also favor shirts with a flashy leaf pattern. Kilana, a female Vorta, sported an appropriately low-cut shirt to [[MaleGaze disarm]] potential adversaries, but the collar still fit this trope.
* FauxAffablyEvil: Vorta are jerks and relish the suffering of races who defied Dominion rule. The big smile is just a pretense.
-->'''Weyoun:''' This is a momentous day. You and I have just taken the first step towards insuring peace between our peoples.\\
''({{smash cut}} to Captain's Office)''\\
'''Sisko:''' [[GenreSavvy They're going to attack.]]
* FoodAsBribe: For some reason, when latinum and flattery doesn't work, Vorta resort to using cuisine as a bargaining tactic. In "The Ship", this crossed over to FanserviceWithASmile: Kilana kept calling time-outs to offer refreshments to Sisko's twitchy crew.
* FlauntingYourFleets: A lone Vorta is no threat at all, but he has a swarm of Jem'Hadar ships and ground units at his disposal.
* GeneralFailure: Their military prowess really isn't the best. The strict hierarchy of the Dominion states that a Jem'Hadar can't question the orders of ''any'' Vorta, even if they're clearly wrongheaded or cruel (such as the Vorta abandoning his entire unit to save himself). Pop quiz: Which of the two races are ''bred for war'', and which is a colorblind wimp who won't even touch a phaser?
* GogglesDoSomethingUnusual & HighClassGlass: The Jem'Hadar don't include viewscreens on their ships: Rather, a slick, shoulder-mounted eyepiece that allows them to observe what's going on outside the hull. There are only two headsets allotted to each ship: One for the Vorta, and another for his Jem'Hadar "First." Cardassians are shown using them with ease, but the headsets cause humans to have splitting headaches after a while.
* HappinessInSlavery: Exemplified when Odo tells a Weyoun that Vorta and Jem'Hadar only view Changelings as gods because they're programmed to. Weyoun's response? "Of course. That's what gods ''do''."
* HenchmenRace
* MindOverMatter: One Vorta, Eris from "The Jem'Hadar", is shown to use telekinetic blasts. [[WordOfGod Ronald D. Moore]] stated that this was an ability the Founders gave to some Vorta, not an inherent trait.
* MouthOfSauron: Every Vorta takes directions from one of the shadowy Founders, then relays them to jarheads further down the chain. Chatting with a Vorta is the closest most people will ever get to meeting the Founders.
* TheNapoleon: Vorta have cooler heads than the Andorians, but on the demerit side, they tend to be quite arrogant and petty. The tallest one we see is Yelgrun, played by IggyPop (admittedly something of a [[WTHCastingAgency miscasting]] according to Word of God).
* TheNeidermeyer: Vorta are particularly callous and cruel toward their soldiers. Sometimes the Jem'Hadar get fed up and vaporize them, but more often they keep a stiff upper lip and take it.
-->'''Sisko:''' I was on a mission with the Jem'Hadar once--before the war, of course. They were good. Tough, professional. [[WorthyOpponent It was an honour to serve with them.]] But their Vorta, ''(grimaces at the memory)'' ...he was something different.
* AnOfferYouCantRefuse: The baseline bargaining tactic for enrolling new planets into the Dominion. Robert Hewitt Wolfe put it succinctly:
-->"Hey, you're nice people, here's some M-16s and some popcorn, and whatever else you want baby, alcohol, fire-water? All you have to do is sign this little contract and we'll make you cool.' Then there's the Jem'Hadar. So the Vorta say, 'Oh, you don't want to play ball? [[SummonBiggerFish Then meet these guys.]] They're gonna kick your asses."
* OneGenderRace: Despite being a genetically-engineered race that is reproduced by cloning, ''unlike'' the Jem'Hadar, Vorta actually appear in both male and female sexes. While never directly stated, it is somewhat implied that as a race of diplomats, the Founders may have kept the Vorta females around because some alien races would be more comfortable dealing with them (either pervy male-dominated societies that could be seduced by them, or female-dominated societies who would have more respect for female diplomats). It is stated that even so, the Vorta do not have sex, and there are (officially, at least) no loving relationships between male and female Vorta.
* ProfessionalButtKisser: In fact, this trope is the hat of the entire Vorta race. They were genetically altered to regard the Founders of the Dominion as living gods. They are well aware of this, and take it in stride. After all, doesn't the Bible say that God created man to serve Him?
-->'''Weyoun:''' What's the point of being a god if there's no one to worship you?
* TheyKilledKenny: If one Vorta gets killed, the Founders just clone him or her again.
* TrademarkFavoriteFood: They enjoy kava nuts and rippleberries, as they did before they were genetically engineered, but little else.
* {{Transhuman}}: They were uplifted from ape-like beings into what they are now by the Changelings. The other main Dominion race, the Jem'Hadar, are also genetically tailored by the Changelings into loyal super-soldiers; it's possible they originated from a more pacifist race.
* WeHaveReserves: The high breeding rate of the Jem'Hadar leaves little room for valuing their lives. In "Rocks and Shoals", Keevan knowingly sends his unit on a suicide run rather than admit to them that he's run out of White. Sisko having to mow down Jem'Hadar from a safe perch leaves a bad taste in the mouth because there is no sense of honour in slaughtering an enemy that cannot fight back.
* YouAreNumberSix: How else do you keep count?
-->'''Damar:''' Clones. Keeping track of 'em's a full-time job.
* YoungerThanTheyLook: Many Vorta, being clones, are younger than they look. Consider Weyoun, who has a propensity for getting killed (often). Many of the Weyoun clones are merely months or even weeks old when we meet them, and *some* have lifespans shorter than a year.

-->''"Victory is life."''

Also genetically-engineered by the Founders, the Jem'Hadar are bred to fight and die on behalf of the Dominion. They are all GattacaBabies (there are no females) and are kept under control due to a genetic and inherent addiction to a drug called Ketracel White. They are also short-lived, but can be produced by the thousands as needed. The Klingons believe that the Jem'Hadar are no more than honorless machines, but they're not as slavish as they look...

* AbnormalAmmo: Their phaser weapons also act as some sort of anticoagulant, causing their target to bleed out if they manage to limp away.
* AlwaysChaoticEvil: A rather tragic justified example. Thanks to the Founders' genetic programming, every Jem'Hadar is a bloodthirsty, xenophobic killing machine, and whilst some have moments of nobility and honour, they're still incapable of entirely going against their nature. A Jem'Hadar may refrain from brutally murdering you once, but once is all you're ever going to get. And, sadly, they're ''still'' the most moral Dominion core race by human standards.
* BadassCreed: "Victory is life!"
** They are required to recite a loyalty oath in exchange for more white. Subverted by the rote nature of the exercise, as well as the constantly looming threat of having your head torn off should you accidentally run out of the drug.
-->'''First''': ''(solemn)'' We pledge our loyalty to the Founders, from now until death.\\
'''Weyoun''': ''(bored, reciting)'' Then receive this reward from the Founders, may it keep you strong. *Sigh*
* BadassDecay: They seem rather easily disposed for such a lethal warrior race, which is explained by Elias Vaughn the result of those mostly fought being only a few weeks or months old at best with no training and only relying on instinct, where as the older ones are much bigger threats,
* BattleCry:
-->''We are dead. We go into battle to reclaim our lives!''
* BattleTrophy: At least one Starfleet commando was spotted wearing a necklace made of Ketracel-White vials, one for each Jem'Hadar he'd killed.
* BloodKnight: This is the race's entire [[PlanetOfHats hat.]] They're imbued with a taste for violence from their creation. Fighting is ''literally'' a need for them.
* CannotTellALie: To the extent that Sisko completely disregards anything the Vorta say, and only negotiate with their messengers.
* CannonFodder: They're superb soldiers, but their uniform characteristics, short lifespans, and the ease of replacing them renders the Jem'Hadar disposable in the eyes of Vorta/Changelings.
* ChurchMilitant: They are simply instruments of God's wrath, nothing more. In "The Jem'Hadar", one of their ships [[RammingAlwaysWorks rammed into]] a retreating Galaxy-class starship (the same class as the ''Enterprise-D''), destroying it. All to send a message.
-->'''O'Brien''': ''(baffled)'' [[SinkTheLifeboats We were retreating.]] There was no need for a suicide run.\\
'''Sisko''': They're showing us how far they're willing to go.
* EvilCounterpartRace: To the Klingons. Both are [[ProudWarriorRaceGuy Proud Warrior Races]] that're literally bred to fight. However, the Jem'Hadar have none of the Klingons' ''Joie de vivre'', their passion for aesthetics, or even their [[TheAlcoholic taste in liquor]]. All they do is fight and kill. As a result, the Klingons come to regard them almost as Boogeymen, and General Martok became nigh phobic of them during his tenure in a Dominion internment camp. For their part, the Jem'Hadar relish the opportunity to fight with Klingons, considering them [[WorthyOpponent Worthy Opponents]].
* FunctionalAddict: Although genetically engineered like the Vorta, Jem'Hadar loyalty is not as reliable, so all Jem'Hadar are addicted to a drug called Ketracel-white, which only the Dominion can provide.
* GeniusBruiser: An unsettling blend of Klingon brutality and Romulan level-headedness.
* HenchmenRace
* LeeroyJenkins: Without a steady supply of "the White", the Jem'Hadar turns into an entire legion of these.
* MeaningfulName: Related to the ranking system in ''KiplingsFinest''. Jem'Hadar do not have ranks with flashy or self-aggrandizing terms. The highest-ranking in a group holds the rank of "First" (roughly analogous to "Captain", if he commands a ship). The rank below "First" is "Second", behind "Second" is "Third", and so on down to at least "Seventh". Individual Jem'Hadar actually ''do'' have names, so we have examples of First Omet'iklan, Third Remata'klan, and Second Ixtana'Rax (an Honored Elder). But while the Jem'Hadar do refer to their squad-mates by name, their Vorta overseers will basically point at them and say "you there, Fifth, make a suicidal charge on that sniper's nest". It emphasizes how replaceable and expendable the Jem'Hadar are to the Vorta.
* NightmareFetishist: When Dr. Bashir treats a wounded Vorta on the battlefield, he gets crowded out by the accompanying Jem'Hadar who are forming a little operating threatre of their own. We see weary resignation upon the Vorta's brow, but not surprise: They've never seen [[AndThereWasMuchRejoicing what the insides of a Vorta look like]].
* NobleDemon: They're violent and fanatically loyal to the Founders, but they have their moments of honor and respect for their opponents and care enough about their fellows that they'd rather kill themselves than become a burden to them; even if this is a programmed response given to them by the Founders, the Jem'Hadar still see this as a NecessaryEvil. Sisko gains enough respect for them that he tells Remata'Klan that the Vorta don't ''deserve'' their loyalty.
** EvenEvilHasStandards: Case in point: A group of Jem'Hadar forms an EnemyMine with Sisko in order to take out a rogue group of Jem'Hadar who had stumbled upon an Iconian Gateway. Using a piece of long lost technology which allows the user to literally travel ''anywhere'' in the galaxy instantly was too powerful (and too unsporting) for anyone to use, even by the Jem'Hadar's standards. They knew they could instantly invade and take over Earth with it, but it's just not who they are.
* NoSocialSkills: Jem'Hadar are intrinsically hostile. They're occasionally shown shooting the breeze with each other, as long as there are no Vorta around. But their relations with other races remain uneasy.
* OneGenderRace: The Founders reproduce the Jem'Hadar through cloning, so they have no need to sexually reproduce. It is directly stated that there are no female Jem'Hadar (and that the males have no sexual desires). The Founders ''apparently'' genetically engineered the Jem'Hadar from some pre-existing stock (similar to how the Vorta used to be primitive ape-like animals before they were uplifted), so it is possible that the ''original'' species had binary sexes of male and female. That is, the modern Jem'Hadar are not technically sexless neuters, they are an all "male" race (they use male pronouns), they just don't have female ''anymore''.
* PhlebotinumDependence: Ketracel White is the only nourishment they need, but it also keeps them from going insane and attacking anything in sight before eventually dying. This dependence further ensures their engineered loyalty. In rare cases, a mutation will cause a Jem'Hadar to lack this addiction.
* ProudWarriorRace
* RapidAging: They can reach their full growth in a few days. Among the ranks, certain Jem'Hadar that have reached the age of 20 are known as "Honored Elders."
* ReptilesAreAbhorrent: They're drug addicted religious zealots who look like humanoid ceratopsians (or possibly Jackson's chameleons). Despite this, however, they're still probably the most pleasant out of all the Dominion races... which really says a lot about the Dominion.
* TheScapegoat: The "order of things" states that the Jem'Hadar commander (or "First") disciplines his own men, and the Vorta leader disciplines the First. Since Vortas have no jurisdiction over troops of lower rank, they tend to come down especially hard on the First.
* {{Seppuku}}: Entire platoons have been known to kill themselves if a Founder dies under their watch. ("The Ship")
* SmarterThanYouLook: They're the quiet, obedient muscle for the Dominion. Doesn't mean they're stupid, as demonstrated in "Rocks and Shoals" when Remata'Klan reveals to Sisko that he knows of Keevan's treachery. But even when they know they're being played, their intense loyalty will (usually) cause them to obey suicidal orders anyway, because the Founders have dictated that they're to obey the Vorta in all things.
-->"Despite what Keevan may think, the Jem'Hadar are often one step ahead of the Vorta."
* TheStoic: They don't emote often. In their dealings with other species, their manner is polished and no-nonsense. Very rarely, they smirk (as one Jem'Hadar did when anticipating [[WorthyOpponent a duel with Worf.]])
* SuicideAttack: Dominion troops love using their ships as homing missiles, making an already-chaotic space battle even worse. During the Battle for Cardassia you can see them zig-zagging and smashing into Klingon and Romulans ships left and right.
* SuperSoldier: And they're damn proud of it, too.
* TragicVillain: The more is learned of the Jem'Hadar, the more it becomes apparent that creating them may have been amongst the Founders' most utterly evil acts. They're completely dependent on a drug that kills them painfully if their supply runs out. They're built to revel in violence and hate non-Jem'Hadar to the point where long-term cooperation with other species is an utter impossibility. Their average life expectancy barely reaches into the double digits (this might ''not'' be biology, but due to a stunningly high attrition rate and "fight till you die" set of orders). Perhaps the worst thing is that despite all of this, they're hard-coded to love and obey the creatures responsible for their miserable state, and to see it as the greatest of gifts to serve them.
* TykeBomb: Created to fight for the Dominion. They age to maturity quickly and can't be dissuaded from seeking out their people and joining the enemy lines.
* VillainousValour: They take pride in their discipline and prowess and are generally treated tragically rather then as faceless mooks. If they were more chivalrous they would be considered [[WorthyOpponent Worthy Opponents]]. As it is, they are perfect foils for the Klingons.
* WeAreAsMayflies: See RapidAging above. Jem'Hadar rarely live past 5 months, and none live past 30, as one Jem'Hadar explained to Jadzia Dax. This is mostly due to them dying in battle before they can reach that point, but their lifespans seem to be that short. Any Jem'Hadar that manages to live 20 years gains the title of "Honored Elder" - they don't form a ruling council or ''officially'' gain a higher rank, they just tend to be respected more for their experience, and because they've served that long they ''tend'' to be Firsts in command of ships or army groups.

->''"My people have a saying: Never turn your back on a Breen."''

A race of nefarious [[{{Halo}} Master Chief]] impersonators who talk entirely in gibberish. Previously mentioned in TNG, very little is known about them. Ordinarily mute and reclusive, they turn into intractable killers when provoked.
* BizarreAlienBiology: And ''how''. The only species never seen in the flesh, for starters. Common knowledge says the Breen hail from a very cold, non-Earthlike climate. However, Weyoun confides that this is a carefully-constructed lie: the Breen homeworld is quite temperate. So what's with the refrigeration suits?
** Dr. Bashir mentioned that a fellow Dominion Internment Camp prisoner, a Breen, was never blood-screened to check if he was a Changeling. Not that they didn't try; there just wasn't any blood to draw from him...
** The Breen are so weird, in fact, that the head Changeling feels way more comfortable around them than with ordinary 'solids'.
* BlueAndOrangeMorality: What little is known about their culture suggests a greater emphasis on pragmatism than the whole good versus evil thing.
* CombatPragmatist: The only true example in the Star Trek universe. Every other race has lines they won't cross, even the Changelings, but not these folks. [[SinkTheLifeboats Shooting escape pods]], [[ColdBloodedTorture torturing prisoners]], and [[AlienInvasion attacking planets]] without so much as a declaration of war is all fair game, to them.
* DangerouslyGenreSavvy: They take no chances when it comes to taking people prisoner. Even when placed in a locked cell, they'll hang their captives upside down by their legs to ensure that they absolutely cannot escape. Before taking a prisoner out to be interrogated, they'll go in three at a time and stun their target before dragging them out of their cell.
* EvilIsDeathlyCold: The Breen are generally considered by other races in the Alpha Quadrant to have evolved in an icy environment. Regardless of whether or not that is true, they are recognized as experts at refrigeration. As Sisko put it, "If anybody knows how to keep things cold, it's the Breen".
* TheGhost: "The Breen" were name-dropped continuously on ''TNG'', as well as ''Film/StarTrekGenerations'', even an episode of ''VOY'', before they finally appeared here. And even then, we learn next-to-nothing about them, greatly emphasizing...
* NothingIsScarier: We learn so little about them -- and what we DO learn about them is so disturbing -- that the Breen more or less ''embody'' this trope.
** A Klingon fleet was sent to conquer the Breen homeworld and was never heard from again. Breen privateers will raid ships in the night, steal their cargo and leave no survivors or trace they've been there. A Breen prisoner will not utter a word until the instant you turn your back, whereupon you're toast. Nobody, but ''nobody'', messes with the Breen.
* OrganicTechnology: [[Series/StarTrekVoyager Tuvok]] mentions that the Breen use Organic Technology much like Species 8472. We don't seem to get confirmation of this on [=DS9=], but it does seem radically different from most other technologies in the Alpha Quadrant.
* ProudWarriorRaceGuy: Subverted. They're very warlike, only they value winning, not honor.
* PsychicBlockDefense: Like the Ferengi, the Breen are said to be immune to TheEmpath.
* ShoutOut: Their outfits look very similar to a certain ''[[ReturnOfTheJedi Star Wars]]'' disguise. This is lampshaded by Col. Kira, a Bajoran, [[DressingAsTheEnemy swiping a Breen's armor]] and leading her two "prisoners" (two Cardassians, in place of Chewie) at gunpoint -- straight into the Dominion stronghold.
* TheUnintelligible: Gargle gargle bleep. One of the few recurring races who aren't heard speaking English.
* VillainCred: That quote up there? Spoken by a ''Romulan''...

[[folder:The Prophets / Wormhole Aliens]]

->''"We are of Bajor."''

* AFormYouAreComfortableWith: They communicate by taking the appearance of one's friends and acquaintances in visions.
* AchillesHeel: Chroniton particles.
* BigGood: Though in more of a morally ambiguous manner than is usual for the trope.
** BlueAndOrangeMorality: Because they're so different from corporeal beings, they have little concept of what humans and Bajorans think is okay.
* BrokenPedestal: A number of Bajorans turn to the Pah-Wraiths after the brutality of the Occupation and the Dominion War, feeling that their gods don't care.
* CrystalDragonJesus: Or rather, Crystal Dragon Angels.
* {{Heaven}}: Their Celestial Temple is this, albiet from a CrystalDragonJesus standpoint.
* IdiotBall: They never get the hint that being cryptic is keeping people from fully carrying out their orders. The fact that the Pah Wraiths are capable of speaking normally logically dictates that the Prophets should be as well.
** Since the Pah Wraiths exist in a physical location in the known universe (the Fire Caves), they became more attuned to linear time than the Prophets, as the Celestial Temple itself does not exist inside the known universe, other than its two entrances that allow it to function as a wormhole.
* MadeOfMagic: They exist as ''something'' but it's damned near incomprehensible to corporeal forms.
* OmniscientMoralityLicense: How they treat the whole Sisko family. [[spoiler:They possess Sarah and force her to have a child with Joseph Sisko, because they know that Ben will be their Emissary. Given that Sarah ran to Australia without a word as soon as she was freed, this was ''not'' consensual, and losing a wife he thought loved him didn't do any favors for Joseph either.]]
* TimeyWimeyBall: They exist outside of linear time, can alter the timeline without the usual side-effects (as in "Ascession"), and gave the Bajorans an artifact that allowed time travel.
** Since they first learned about linear existence from Sisko, this implies that their impact on Bajoran culture and ensuring Sisko [[spoiler: was born]], may have been a [[StableTimeLoop direct result]] of this "future" meeting.

[[folder:The Pah Wraiths]]
->''"Everyone has enemies, even the Prophets."''

* AllJustADream: Tried to fool Sisko into thinking his life on Deep Space 9 was this.
* AlwaysChaoticEvil: Of course, being demons, they're pretty much this by default.
* BiggerBad: The ultimate bad guys of the series, though they hardly show up, even at the end.
* ColorCodedForYourConvenience: The Prophets are blue colored, but these guys are orange.
* CrystalDragonJesus: Crystal Dragon Demons sums it up.
* EvilCounterpart: To the Prophets.
* GrandTheftMe: A favored tactic of theirs when they want to take a direct hand in things.
* FireAndBrimstoneHell: Their home in the Bajoran Fire Caves is this.
* MadeOfEvil: The entirety of their characterization.
* PragmaticVillainy: They are surprisingly manipulative and underhanded in their methods. Not a single shade of StupidEvil, unlike the Dominion, who routinely kill off their own for minor infractions.
** Then there's the fact that the Pah Wraith in ''The Reckoning'' chose Jake Sisko as its host, specifically because it understood corporeal relationships and who Jake was related to.
* RageAgainstTheHeavens: Tried this in ''Tears of the Prophets''. It eventually failed and got them cast back out.
* RedEyesTakeWarning: Seems to happen by default when they posses someone, although ''The Assignment'' confirms that they can suppress it when necessary.
* SealedEvilInACan: Rather, sealed evil in some caves, as well as a small ornamental statue.

!!Species debuting in ''Voyager''

->''"I can't believe that our Caretaker would forbid us to open our eyes and see the sky."''

Ocampas are shrouded in mystery, but their own legends tell of a time when they were capable of great mental feats. Nowadays, they eke out a dull existence as the fragile, cloistered wards of an unseen overseer. ''Trek'' has depicted unlikely examples of evolution in its time, but the Ocampa take the cake: They live an average of nine years, their females develop a sticky mucus on their palms during mating, produce offspring out of an "egg-sac" on their back, and can deliver only one baby per lifetime. Take ''that'', Darwin.
* AscendToAHigherPlaneOfExistence: Kes experienced a rapid and uncontrollable blossoming of her mental abilities in adulthood. She left the ship and allowed this process to complete itself, apparently evolving into a being of pure energy.
** Tanis also claimed that Kes could join Suspiria in a subspace layer called Exosia, which he described as a realm of pure thought.
* BeneathTheEarth: The Nacene, upon realizing their mistake, took upon themselves the responsibility of caring for the Ocampa. The Caretakers built a massive underground cavern with access to the only remaining natural water source on the planet and supplied it with energy via transmissions from an orbital "Array."
* MindOverMatter: All Ocampa appear to be natural telepaths, able to communicate across great distances (putting the Vulcans to shame). Among the more colorful abilities are [[NewPowersAsThePlotDemands photographic memory, precognition, telekinesis, pyrokinesis, time travel, and the ability to alter matter on the subatomic level]].
** Tanis, an Ocampa living on Suspiria's array, demonstrated to Kes that she could control living things, causing them to [[WalkingWasteland grow or die as she wished]].
* RapidAging: Ocampa age very rapidly, resulting in an average life span of only nine years (less than that of a household pet). As an upside, they develop and learn extremely quickly.
* WeHaveBecomeComplacent: As a result of their lifestyle of ease under the Nacene, the Ocampa eventually stopped using their mental powers, causing them to atrophy.
* WritersCannotDoMath: As pointed out by {{SFDebris}}, at peak reproductive rates the population would halve every generation since females can only produce a single offspring once. A species this short-lived really ought to produce litters. This means one of two things: That the evolution of the Ocampa race was interrupted when the Nacene took over, altering their genetic code (thus requiring the constant supervision of the Nacene), or that the Ocampa naturally mature into pure energy, rendering their corporeal lives somehow moot.

->''"As they say on Talax: "Omara s'alas - [[IceCreamKoan Good news has no clothes.]]"''

A race of space warthogs who inhabit many sectors of the Delta Quadrant (Like the Kazon, their race was scattered following a war). They share much in common with Bolians, including a knack for cooking - though their jolly nature is taken UpToEleven.

* ClassyCravat: The men all wear these.
* FireBreathingDiner: It was hinted at that Talaxians have a higher tolerance for spicy foods than other races. In "Faces", Neelix prepares a 'watered-down' plomeek soup, a mere sip of which knocks a sturdy Vulcan flat. Neelix, however, is able to guzzle down the soup as a beverage.
* HollywoodToneDeaf: Talaxian vocal cords are actually incapable of singing on-key, though Neelix managed to wheeze out a halfway-decent ditty.
* HotBloodedSideburns: Negated by Talaxian pacifism. However, tugging on their whiskers is considered a pleasurable come-on.
* OurGnomesAreWeirder: Not a direct inspiration for [[StarWarsThePhantomMenace Jar Jar Binks]], but pretty close.
* TheScrounger: This seems to be their speices' hat.
* SpareBodyParts: Surprisingly, Talaxians have two spinal columns, similar to Klingons.

->''"A fitting end for a people who would not share their technology. Let's see if you manage to survive... without it."''

Another spinoff, another replacement Klingon. The Kazon have a checkered devlopment history, originally inspired by the Crips and Bloods. They represent anarchy, in opposition to ''Voyager'''s attempts to carve out a fledgling Federation. However, as the series went on and the actors got older, the "youth gang" theme was thrown out, and they became generic warriors.

* AlwaysChaoticEvil: A rare completely straightforward example in modern Trek series'. Unlike the Borg or Jem'Hadar, who are given in-universe justifications for their unbending ways, the Kazon appear to be simply [[ForTheEvulz evil on purpose]]. The fact that they're never given much characterization beyond this accounts for much of their unpopularity.
* BeingTorturedMakesYouEvil: The Kazon were once a SlaveRace employed by their Caucasian rulers, the Trabe, and it's stated that the entire galaxy now rues the day their earned their freedom. [[UnfortunateImplications Erm...]] The Kazon are a confused mess of storytelling by writers who intended it as a commentary on redlined city districts and the cycle of crime, but for whatever reason, the species fell back into the famliar "Warlike Alien" role which ''Trek'' is used to, and their oppressors were painted with a softer (even [[BrokenAesop sympathetic!]]) brush.
* BigBadWannabe: Michael Pillar, who co-created the Kazon, was the major driving force in making them VOY's main adversaries. Jeri Taylor was the first writer to abandon the idea of making them viable villains, later followed by Brannon Braga.
* DisasterScavengers: Early on, they turn their attention to the Caretaker's Array, but when Janeway destroys it, the Kazon vow to capture and dissect ''Voyager'' instead.
* DivideAndConquer: One of the Trabe's tactics in keeping the Kazon in line was to encourage them to in-fighting amongst the clans, or "sects." However, the sects learned to put aside their differences and rose up against the Trabe. In doing so the Kazon took the Trabe's ships and technology, forcing them to become a nomadic species, and never allowed them to settle on a new world. (VOY: "Initiations", "Alliances")
* DumbMuscle & OurOrcsAreDifferent: The Kazon are big, boisterous, and dumb. A cunning Cardassian agent, known as Seska, was able to insinuate herself into the Nistrum sect in no time flat.
* EconomyCast & TheUsualAdversaries: For a nomadic tribe of brigands, they sure do seem to control a huge diameter of the Delta Quadrant. By Season Three of VOY, even Exec. Producer Rick Berman had had enough:
-->"If you think about it, traveling for a year-and-a-half through a part of space dominated by one group is pretty amazing! I think traveling at warp speed for a year-and-a-half you would pass through the Federation, the Klingon Empire and a few other places."
* EvilCounterpartRace: As the Jem'Hadar are to ''[=DS9=]'' and the Gamma Quadrant are the Kazon to ''VOY'' and the Delta Quadrant. The Kazon are no Jem'Hadar, though... (OR Klingons, for that matter)
* TheGuardsMustBeCrazy: A Kazon prison is a line drawn on the floor that the prisoner is told not to cross. Sigh.
* InsufficientlyAdvancedAlien: The Borg found the Kazon so utterly unremarkable that they refused to assimilate them, on the grounds that it would add nothing to the Collective. And yet ''Tribbles'' are a-OK!
* LowCultureHighTech: The Kazon don't exactly inspire confidence with their technical abilities. However, they only recently acquired it, namely by overthrowing their Trabe conquerors.
* MeetTheNewBoss: They were intentionally modeled on the Klingons right down to their makeup, so this comes as no surprise.
* NoBloodForPhlebotinum: Somewhat bizarrely, in Star Trek: Voyager, the Kazon, an oxygen-breathing species traveling in hydrogen-powered ships, will kill, steal, or trade hostages for '''water'''. When he first arrives on the ship, Neelix is similarly shocked by Alpha Quadrant species' ability to synthesize water.
* PlanetLooters: Basically, the Kazons' advancement as a civilization has come entirely from piracy. They are a primitive people with no understand of the technology they steal, or how to reverse-engineer it.
* ARealManIsAKiller: In another VOY episode, a Kazon boy wishes to become a man by killing Chakotay. He then explains that killing a person is the rite of passage for the Kazon; apparently, killing a clansman is also acceptable in some cases. At the end of the episode, instead of killing Chakotay, he turns the weapon onto his maj, becoming the new maj in the process (similar to the Klingon Promotion).
* SpaceJews: The marriage of the three sects resulted in an arrangement not unlike the Arab League.
* TheRevolutionWillNotBeCivilized: The Kazon were once a subjugated race, used as slave labor by the Trabe, who had conquered their homeworld.

->''"Oh, well now, aren't you contentious for a minor bipedal species."''

Not much is known about the Nacene. They are explorers in their own right, hailing from another galaxy. One particular alien, dubbed "The Caretaker" by his Ocampa followers, [[MyGodWhatHaveIDone mistakenly destroyed their planet]] while crossing over from its own dimension. As penance, the Caretaker devoted the remainder of its life to preventing the extinction of their race. Shortly after abducting ''Voyager'', and recognizing that its death was imminent, the Caretaker requested to Captain Janeway that the Kazon should not be allowed to use his array, forcing her to destroy it.

* TheAtoner: The Naceneare had no idea that their technology would be so destructive to the Ocampan atmosphere. They could never repay the debt, and so two of the Caretakers stayed behind to feed them energy and water.
* AuthorsSavingThrow:[[invoked]] Suspiria was initially conceived of as a "get out clause", designed to change the format of VOY if such a need arose. This was because the Paramount executives were leery of the lost-in-space premise that was central to the story, and wanted an ejection button prepared in case the show didn't perform well. As it turned out, the Caretakers appeared only twice, and ''Voyager'' found other methods to get back home.
* BlobMonster: The Caretaker is a great big translucent blob. His mate, Suspiria, is a tentacled pillar of goo.
* DidYouJustRomanceCthulhu: At the start of VOY, the Caretaker has reached the end of its 1,000-year lifespan and could no longer maintain the Ocampa habitat. It begins snatching random spacecraft from various ends of the Milky Way to find a suitable mate (as you do).
* HisNameIs: The Caretaker dies of old age before he can return ''Voyager'' to the Alpha Quadrant. Whether he ever intended to do so is a mystery.
* HostileTerraforming: Accidental. The engines of the Nacene's exploratory vessel caused a contamination in the atmosphere of the planet, reducing it to a desert.
* AFormYouAreComfortableWith: The Caretaker first appears to the ''Voyager'' crew as an elderly human, Banjo Man. Suspiria cloaks herself in the guise of a CreepyChild in a Victorian dress.
* LastOfTheirKind: The Caretaker was left high and dry after his companion, Suspiria, parted with him over ideological differences.
* NoBodyLeftBehind: The Nacene shrink down into a tiny piece of crystal when killed.
* PowerFloats
* SufficientlyAdvancedAliens
* ThisWasHisTrueForm: The Caretaker only reveals his real form when a Kazon warship crashes into the array, causing his holograms to fail. This exposes the 'farmhouse' as the interior of an alien ship.
* WhatHappenedToTheMouse: One of them is still out there somewhere…
* WomanScorned: The Caretaker did not realize that his philanthropy was rendering the Ocampa utterly dependent on his assistance. His mate, Suspiria, did realize this and left the planet, taking a small group of Ocampa with her. She later hunts down ''Voyager'' to avenge the Caretaker's death.

->''"It must be impossible for you to understand how any civilised people could come to this."''

The Vidiians are {{Mad Doctor}}s, possessing medical technology far more advanced than Starfleet. They've had a lot of practice, as they must constantly replace their skin and organs with transplants (often stolen) to remain alive. They suffer from a necrotizing plague called "the Phage", which causes their bodies to devour their own flesh.

* AllGenesAreCoDominant: They are able to steal organs from every other sentient race for transplant with no risk of rejection, a feat which even current Federation medical science cannot replicate. Despite this, they seem unable to actually cure the phage to begin with.
* DeadlyDoctor: Vidiians wield a surgical instrument as a weapon. It acts as a combination phaser, medical tricorder, and transporter tag.
* DrivenToVillainy: The Vidiians are driven to their organ raids out of extreme desperation; before the Phage struck, they were a peaceful and cultured race of scientists.
* FacialHorror: The current crop no longer even remotely resemble their original selves.
* MeaningfulName: The name for the disease comes from Greek φᾰγεῖν phagein, which means "to eat". The organs of people suffering from the Phage literally devour themselves.
* MisappliedPhlebotinum: The Vidiians are able to split hybrid humanoids into fully functional beings. Doing so, they should be able to create as many organs as possible to meet their needs, or cure the Phage.
* MixAndMatchMan: Their bodies are patchwork of different alien skins -- anything they can lay their hands on.
* SomethingWeForgot: The Phage was eventually cured by the same alien "Think Tank" which tried to recruit Seven, but ''Voyager'' had long since passed Vidiian space by then.
* VileVillainSaccharineShow: Their makeup and modus operandi is rather grotesque compared to the rest of the show, especially considering the toned-down Borgs that appear later. In the aptly-titled "Faces", one of the Vidiians steals a goldshirt's face and applies it over his own.
* WeaponizedTeleportation: With their hand-held weapons, Vidiian organ harvesters can zap a victim and "beam" organs straight from their bodies.
* TragicVillain / WasOnceAMan: The Vidiians are introduced as a race of Frankenstein's monsters, composed of a grotesque patchwork of body parts taken from other species, which in turn are deteriorating due to the phage. It's fairly jarring when in a later episode they compile a holographic recreation of what a healthy, uninfected Vidiian would look like: they basically look ''like humans'', without even much Rubber Forehead Alien going on. Their hairline is a bit taller (sort of a reverse-widow's peak), and they have a ''slight'' forehead ridge, a single line extending up from the nose to their hairline, but otherwise, like humans. The contrast lets you see just how badly the phage has ravaged their bodies (compared to if a healthy Vidiian looked like a Klingon or a Ferengi). They make the holographic recreation so they can interact with a comatose female Vidiian doctor (linking her brain to the holo-projectors). Even though her brain will die if it stays hooked up to the holo-projectors for more than a few weeks, for a time she seriously considers [[DyingAsYourself that living for a few weeks as a healthy person]] would be preferable to a long life trapped in her decaying, patchwork body. She also apologizes that the Vidiians were driven to their organ-snatching by utter desperation, until after a while many of them just stopped caring where they got the parts from.

[[folder:Species 8472 / Undine]]
->''"They are the apex of biological evolution. Their assimilation would have greatly added to our own perfection."''

The only species the Borg truly fear. They hail from another dimension called fluidic space, and are territorial rather than outright hostile. One of the few {{Starfish Alien}}s to have a regular role on Star Trek.
* AbsoluteXenophobe: All that is known of Undine aka Species 8472's culture is that they are highly territorial; they consider all other lifeforms to be genetically impure. Any intruder entering fluidic space is seen as 'contaminating' the realm, and is dealt with accordingly. (VOY: "Scorpion", "Scorpion, Part II")
* AbsurdlySharpClaws: The main mode of attack. One swipe can decapitate a helmeted Hirogen.
* EnemyCivilWar: Versus the Borg. Contrary to what the Borg claim, the Undine are not aggressors; it had in fact long been known that the Borg themselves started the war between the two species by invading fluidic space to assimilate their technology.
* EvilerThanThou: They're [[ExaggeratedTRope more lethal than even]] ''[[ExaggeratedTrope the Borg]]''. Yes, the [[TheJuggernaut near-unstoppable]], [[HordeOfAlienLocusts all-consuming]] cybernetic HiveMind that has been the terror of the galaxy for centuries is completely outclassed by the genetically superior, highly territorial eldritch aliens. The Borg want to assimilate everyone into their collective; Species 8472 wants to [[AbsoluteXenophobe annihilate every other living thing]] because they consider it an affront to their vaunted purity.
* EvilIsVisceral Their ships are organic and the (CGI) aliens themselves look "more organic" than the usual Rubber Forehead Alien because they don't wear clothes, have extra limbs and strange eyes with complicated irides. Also, they hail from something called fluidic space.
* AFormYouAreComfortableWith / HumanoidAbomination: Concerned about the threat posed by ''Voyager'', the Undine don meatsuits and builds a recreation Starfleet Academy within as a staging ground for an intelligence gathering mission on Earth. The plan is uncovered by ''Voyager''' and peace talks commence. ''Voyager'' convinces the Undine, led by an individual posing as Boothby, that the Federation has no quarrel with them.
* GeniusBruiser: Species 8472 is telepathic and can send Kes and Tuvok messages.
* HellishPupils
* KryptoniteProofSuit: Their autoimmune system also makes them impervious to Borg assimilation. Undine blood simply rejects the nanites.
* LivingShip: Undine travel around in a type of organic spacecraft known only as a bioship, which is composed of the flesh as their pilots. The bioship's main weapon is powerful enough to destroy a Borg cube in only a few shots. Likewise, when a Borg cube rammed a bioship, ''both'' vessels were blown to bits despite the comparatively smaller mass of the bioship. The weapons of eight bioships (referred to in Star Trek: Armada II as "Species 8472 battleships") can combine firepower to destroy an entire planet.
* ManipulativeBastard: Secton 31, Tal Shiar, Obsidian Order, The Founders? Yeah they're nothing compare to Species 8472.
* PoisonousPerson: Their somatic cells can become extremely virulent when in a foreign blood-stream. When a member of Species 8472 attacks a victim with its claws, some of the former's cells are left in the wound. These stray cells multiply rapidly, consuming their prey from the inside out while the victim remains conscious.
* HealingFactor: Their regenerative cells work incredibly fast, as demonstrated in the episode "Prey", when a Undine is attacked by a Hirogen hunting party with heavy weapons. Thinking it dead, they take it back to their ship, [[PlayingPossum only to discover otherwise...]]
* YouAreNumberSix: Species 8472 is their boilerplate Borg designation. Their Starfleet moniker, "Undine", was introduced in ''Star Trek Online''.

->''"The way a creature behaves when it is wounded is the key to its destruction."''

The Hirogen are a dominant Proud Warrior Race in the Delta region, roaming vast distances in pursuit of worthy prey. WordOfGod made no bones about drawing inspiration from ''Franchise/{{Predator}}'', which shares their veneration of 'the hunt', the collection and display of hunting trophies, the use of a breathing apparatus for alien atmospheres, and so forth.
* AppliedPhlebotinum: Their "tetryon" weapons are unfamiliar to Starfleet. their ships also have "monotanium" armor plating. This plating has the added effect of scattering phaser blasts. (VOY: "Hunters")
* AwesomenessByAnalysis: Hirogen culture required a hunter to study his prey to understand its abilities.
* BattleTrophy: Not only for bragging rights, but also an instrumental part of their mating ritual. Female Hirogen are attracted to hunters in possession of rare or unique trophies acquired during a hunt.
** One of them threatens to remove Seven of Nine's intestines as a trophy, as "Unusual relics are prized. Yours will make me envied by men and pursued by women!" Seven, who rivals the Hirogen in the big ego sweepstakes, is unimpressed.
* EgomaniacHunter: Inverted. The Hirogen, as a rue, do not empathize with their prey. However, in keeping with the Native Americans themes, they prefer to kill their targets quickly and painlessly.
* HuntingTheMostDangerousGame: In "The Killing Game" two-parter, a pack of Hirogen ships trapped the crew to in [[SimulatedUrbanCombatArea a vast WWII holoprogram]] to better study their battle capabilities.
* LackOfEmpathy: The Hirogen alpha in "Demons of Air and Darkness", who, like most Hirogen, relates to other sapient beings only as prey. At one point, he reflects on how one of his victims cried that she had a husband and children, "as if the family structure of prey was of any relevance."
* MalevolentMaskedMen: While wearing their breathing masks.
* PuttingOnTheReich: "The Killing Game" featured the Hirogen capturing the Voyager crew and forcing them to re-enact WWII, with the Hirogen taking the part of the Nazis in occupied France. They wore their Nazi uniforms when outside the holodeck too. Somewhat averted, in that only one of them is truly enamored with the Nazi philosophy - the leader is ready to strike a deal with Janeway in exchange for the holodeck technology.
* SpikesOfVillainy: Hirogen armor.
* TriageTyrant: In "The Killing Game", When a crewmember with life-threatening injuries and a Hirogen with minor burns are both brought in, the Hirogen medical officer orders the Doctor to treat the Hirogen patient first. The Doctor protests that this goes against the rules of triage. The Hirogen replies "your rules, not mine" and switches him off when he refuses to comply.
* TurnedAgainstTheirMasters: In "Flesh and Blood" the Hirogen are using holograms to train for the Hunt. Unfortunately they get smarter and smarter after being hunted down and killed constantly until...
* VictoryIsBoring: Hirogen have been known to express disappointment when the species they're hunting proves to be unchallenging. (VOY: "Hunters") As a result, being called "[[WorthyOpponent worthy prey]]" by a Hirogen was meant as a great compliment.

[[folder:The Hierarchy]]
->''"Acceptable risk. The Hierarchy approves."''

One of the last species to be encountered by ''Voyager'' on their return trip to the Beta Quadrant. Though visibly based on ''DoctorWho'''s Sontarans, the Hierarchy is their polar opposite in terms of machismo. They are scavengers who, due to their unwieldy bodies, rely on wiretaps and long-range espionage to survive.

* FatBastard: Though the Hierarchy are not particularly malicious, just opportunistic.
* HighCollarOfDoom
* PragmaticVillainy: The Hierarchy weight everything in terms of risk vs. reward.
* StealthInSpace: Seem to be the only race in the entire Delta Quadrant with Cloaking Technology. Even then, it just takes some Sensor Remodulation to spot them, so obviously their's isn't as advanced as the Klingons or Romulans.
* VastBureaucracy: The social structure of the Hierarchy is regimented in such a way in that each crew member has a single work station and duty to perform, minimal social interaction, and limited access to the rest of the ship.


!!Species debuting in ''Enterprise''

->''"The Suliban don't share humanity's patience with natural selection."''

* BaldOfEvil
* RubberMan: The Suliban were originally just a backwards race from a nondescript world. Thanks to Future Guy's genetic meddling, they now have a host of superpowers, including the ability to squeeze through tight cracks.
* WhatHappenedToTheMouse: In the 23rd and 24th centuries, despite being a well-known species in the 22nd century.


->''"I thought human reproduction was complicated. You Denobulans make us look like single-cell organisms."''

On their homeworld of Denobula, the twelve billion Denobulans all share one continent. Consequently, living space is at a premium and Denobulan culture had come to embrace polyandry and communal lifestyles. All in all, Denobulans are pretty weird. They can inflate their heads (similar to a pufferfish) when threatened, have {{Overly Long Tongue}}s, mood-ring eye colors, and a ridiculously creepy grin.

* BioAugmentation: Subverted. Phlox states that the Denobulans have been using genetic engineering since the twentieht century - but only under strict regulation, to repair what would otherwise be debilitating genetic conditions (blindness, late-onset insanity, etc.) But he adamantly points out that they only use such technologies responsibly: to ''repair'' and never in an attempt to "improve" on their basic biological template to create a race of supermen. They never went through an analogue of the Eugenics Wars like humans did, with genetic "supermen" like Khan.
* BourgeoisBohemian: The Denobulans are perfectly happy in their mixed marriages, as it meant relatives could leave for extended periods and not inconvenience the family. Truthfully, Phlox admitted, he'd begun to miss the company of some of the other husbands. (Ahem.)
* GoMadFromTheIsolation: The Denobulan homeworld only has one relatively small continent, and a population of 12 billion. As Phlox directly explains, they could have kept the number smaller with population controls or spreading to space colonies once they developed light-speed travel, they simply ''chose not to''. Their society evolved to be very communal, with multiple polygamous marriages for both men and women at the same time. Denobulans prefer crowded habitats to socialize with large numbers of other people, and they actually can't ''stand'' being completely alone. In one episode the rest of the crew has to be sedated for weeks to pass through a dangerous patch of space, except for Phlox whose physiology is not adversely affected (and so he can monitor the crew). He has to spend the entire journey alone by himself. By the end he becomes increasingly paranoid and starts suffering from hallucinations.
* Polygamy/ExoticExtendedMarriage: Denobulans are both polygynous and polyandrous. Dr. Phlox has three current wives, each of whom have three husbands (him and two other men). One of his wives appears in one episode, and he has no problem that she is sexually interested in Trip. From what little we have seen of the Denobulans they are not sexually outgoing or adventurous (they're not Deltans), they just have a casual and relaxed attitude towards sexual relationships. Their social structure is simply very complex and well, "alien".
* PufferFish: When threatened, their heads explode to three times their normal size because why not.
* WhatHappenedToTheMouse: Despite having ties to Earth, they're not heard from past the 22nd century.
** At least 1 appeared as background characters is ''Star Trek: Elite Force II'', along with several [=NPC=]s in ''Star Trek Online''.


->''"Even after Earth is destroyed, there will be residual presence in the system. I intend to hunt down and eradicate every refugee caravan, every colony, every last outpost they have."''

A unique race consisting of five distinct sub-species: primates, arboreals, reptilians, insectoids, and aquatics.
* ArtisticLicenseBiology: Of the "You fail biology forever" variety. There are six Xindi races, all of which evolved on the same planet. They are directly stated to be "about as genetically different as humans and Neanderthals"...two of the races are one human-like one, and one humanoid sloth-like race. On some outside chance, primates and sloths are ''loosely'' related given that they are mammals. The next is an aquatic dolphin/seal-like race. Okay, maybe an aquatic ape adapted to living in the sea. The Xindi-Avians went extinct in the war that destroyed their homeworld so we never got to see one (a giraffe-skull was used to represent their skull). But...the Xindi-Reptilians are blatantly lizard-men, yet are still "about as different from the Xindi-Humanoids and Xindi-Arboreals (Sloths) as humans and Neanderthals"? The point when you'll stand up shouting at your TV is that one of the Xindi subspecies are the Xindi-Insectoids. Yes, vaguely humanoid insects. ''Vertebrates'' and ''Arthropods'' are not that closely related!
* FantasyAxisOfEvil
* NotSoOmniscientCouncilOfBickering: And ''how''. Even when united in wanting to wipe out Humanity, they simply ''cannot'' stop arguing. First it was about what methods, form and delivery the attack should take, then after they fixed on the PlanetKiller design, they began arguing about when and how it should be deployed.
* WellIntentionedExtremist: The Xindi were tricked into believing that humanity would wipe them out in a few years.
* WhatHappenedToTheMouse: One of Earth's most prominent enemies from its early days of exploration, and is never heard from again past the 22nd century.
** Recently added to ''Star Trek Online'' as bridge officers, duty officers, useable reptilian & aquatic starships and at least 1 NPC.


[[folder:Sphere Builders]]
->''"In the service of the Makers, all actions are blessed ones.""''

* GodGuise: The Xindi referred to the Sphere Builders as "the Guardians," and revered them as religious figures. After the destruction of the Xindi homeworld, the Builders appeared to the Xindi survivors (convenient, that), lending them maps to habitable planets and resources. Similarly, the Triannons referred to them as "the Makers," and believed that they were transforming the Delphic Expanse into a paradise for their eventual return.
* HostileTerraforming: The Spheres are used to make planets habitable for their race prior to invasion. Contrary to their name, however, they aren't actually responsible for building them - just providing the blueprints.
* TimeTravelForFunAndProfit: Using their inter-dimensional abilities, the Builders forsaw that the Federation would repel their eventual invasion, and sought to snuff Earth out preemptively.
