|Race||Home planet||Episodes |
M = mention only
|Acamarian||Acamar III||"The Vengeance Factor" (TNG)|
Acamarians are a generally peaceful race with a history of violent clan wars. Physically, they can be distinguished by a vertical crease in the center of the forehead. A splinter group, known as the Gatherers, composed of members of various Acamarian clans who opposed the peace treaty for about 100 years, was eventually repatriated into Acamarian society.
|Aenar||Andor (Andoria)||"United" (ENT)|
|Aenar, along with the Andorians, inhabit the world of Andor (Andoria). In many regards, they are similar to the Andorians in physical appearance. However, their skin is a light blue/white color, they are almost totally blind, and they have powerful telepathic abilities. Aenar are pacifistic and do not use their mind reading abilities against the will of another individual. However, their blindness does not appear to hinder their ability to know that they are in the presence of a "blueskin" Andorian or detect obstacles.
Aenar government, such as it is, has little structure; leaders of Aenar society are chosen as the need arises, usually when contact with outsiders is called for. The Aenar are usually considered to be just a different ethnicity of the Andorian race and not an utterly separate species.
The Aenar population is about 11,000 in size and they inhabit the polar region of their world. Andorians believed the Aenar to be mythical creatures before their existence was confirmed circa 2104.
|Akritirian||"The Chute" (VOY)|
|The Akritirians are an advanced humanoid Delta Quadrant race with basic interstellar spaceflight, perhaps warp-capable. A dictatorship controls the planet, now dealing with an Open Sky group fighting to overthrow it.
Felons are kept in an isolated spacegoing station – as the USS Voyager's Paris and Kim discover when wrongly sent there. Pardons or rehearings in convictions and sentencing are never heard.
|Allasomorph||"The Dauphin" (TNG)|
|An Allasomorph is an anthropomorphic shapeshifting species.|
|Andorian||Andoria||"Journey to Babel" (TOS)
|Andorians are a humanoid species with blue skin and antennae. They consider themselves a warrior race, in contrast with the pacifist Aenar who also live on the Andoria. They are native to the moon Andoria, which orbits the planet Andor. They were a founding member of the United Federation of Planets.|
|Antaran||"The Breach" (ENT)|
|The Antarans are mentioned by Doctor Phlox to have been at war with the Denobulans on several occasions. The Denobulans have tried to put the war behind them; however, there are still Denobulans who hate the Antarans. The Antarans remain bitter and are raised from birth to hate Denobulans.|
|Angosian||"The Hunted" (TNG)|
|Usually considered non-violent, Angosian authorities were responsible for genetically and chemically engineering soldiers to fight in their Tarsian Wars. But the process was irreversible, and the 'super soldiers' were considered outcasts and criminals that could not function or co-exist alongside the normal population of Angosian society, and as such were forced to be permanently confined to a penal settlement on an Angosian moon.
|Antedean||Antede III||"Manhunt" (TNG)|
|The Antedeans from Antede III are an ichthyohumanoid species which resemble fish. While a member of the United Federation of Planets, they seldom receive visitors and thus have not been seen by many members of the Federation. Another trait that keeps them from interacting with their fellow Federation members is a strong distaste for space flight: although the Antedeans are a space-going race, space travel is quite traumatic for them. In order for individuals to deal with this problem they induce a catatonic state while in space flight. To awaken from this state takes several hours. Once awakened from the sleep Antedeans are generally ravenous and eat large portions of vermicula.
There is a division in the Antedean race on whether membership in the Federation is a good thing. Ambassador Lwaxana Troi foiled a plot on Stardate 42859.2 when 2 Antedeans tried to sabotage their planet's Federation membership conference on Pacifica with ultritium concealed in their garments.
|Antican||"Lonely Among Us" (TNG)|
|The Anticans are dog-like with snouts, dark fur and white hair. They applied for Federation membership but the ruling decision was put off because of their hostilities with their neighbors, the reptilian Selay. In a quest for meat, the Antican diplomatic team attempted to cook and consume a member of the Selay delegation.|
|Arcadian||Star Trek IV: The Voyage Home|
|Arcadians have large, round, doll-like heads and have hair on the left and right sides of their heads with none in the middle. They are members of the United Federation of Planets with a representative on the Federation Council. They joined at least as early as the 2280s.|
|Arcturian||Arcturus||Star Trek: The Motion Picture|
|Arcturians are known for their clones which have the appearance of melted skin and hail from the densely populated world Arcturus.
|The Axanar are the first extraterrestrial race befriended by Earth people aboard the NX-01 Enterprise. Archer and his people attempt to rescue Axanar aboard a ship that has been disabled, but they are already dead, and when both another Axanar ship, and the preying ship, show up, Archer is able to persuade the Axanar to help him fight off the preying ship.
One of James T. Kirk's earliest commendations is the Palm Leaf of Axanar Peace Mission, following the Battle of Axanar; although the exact nature of the conflict is unrevealed, it is revealed in the episode "Whom Gods Destroy" that Starfleet Captain Garth of Izar achieved a great victory on behalf of the Federation, and his strategies became required reading at Starfleet Academy (since Kirk himself studied these strategies, the Battle of Axanar must thus have occurred well before Kirk entered Starfleet Academy in 2250, which was itself almost 20 years before "Whom Gods Destroy"). Kirk claims that the Axanar Peace Mission "topped [Garth's victory] with a greater one" and preserved the civilization that made Spock and himself "brothers", implying that the mission may have contributed to healing a serious rift in the Federation at that time.
|Race||Home Planet||Episodes M = Mention Only|
|Bajoran||Bajor (M-class)||"Ensign Ro" (TNG) |
|The Bajorans are a humanoid species with characteristic nose creases. They live on the planet Bajor. They are a deeply spiritual people, who worship The Prophets. They are enemies of the Cardassians, who occupied Bajor and treated the Bajorans as slaves in the early 24th century.|
|Ba'ku||Unknown, The Briar Patch||Star Trek: Insurrection|
|The Ba'ku people were a technologically advanced humanoid civilization. In the early 21st century, the race developed the means of building weapons of mass destruction and was on the brink of self-annihilation. A small enlightened group of the Ba'ku people escaped this horror and found an isolated planet.
This group of Ba'ku followed a simple way of life and disdained the use of technology. (As shown in the film Star Trek: Insurrection, however, the Ba'ku still possessed some form of technology and the ability to use it in emergencies, since they had attempted to repair the damaged Data.) At first the Ba'ku were unaware of the metaphasic radiation in the planet's rings, which caused their aging process to significantly decelerate, although it was later discovered and cherished.
The Ba'ku society consisted of strong bonds between each individual as there were less than a thousand living in a village. Their simpler way of life eventually prompted some of the younger Ba'ku villagers – who wanted to explore the galaxy with offlanders – to rebel against their elders, and an attempt was made to take over the village. When they were unsuccessful, they were exiled and eventually became the Son'a people.
In 2375 peace on the Ba'ku planet was restored, and several members of the Son'a returned to their families.
|Bandi||Deneb IV, fourth planet in the Alpha Cygni system||"Encounter at Farpoint" (TNG)|
|The Bandi are a humanoid species native to the planet Deneb IV in the Alpha Quadrant. The Bandi applied to the United Federation of Planets for membership in 2364 but were rejected because they had captured and enslaved an alien life form.
Perhaps purely by coincidence, "Bandi" was the name of a vaguely ursine empathic parasite in an early Star Trek story premise by David Gerrold, who was involved in the development of Star Trek: The Next Generation, and who novelized "Encounter at Farpoint".
|Ba'ul||Kaminar||"The Sound of Thunder" (DSC)|
|Ba'ul are a race who use their technological superiority to feast upon the Kelpien people.|
|Berellian||Unknown||"Redemption" (TNG) M|
|When Lieutenant Commander Data takes temporary command of the USS Sutherland during the Klingon Civil War, his first officer on the Sutherland, Lieutenant Commander Thomas Hobson, argues that, as an android, Data is out of place commanding a Federation starship. Hobson compares the presumed incompatibility of Data’s nature, and his assigned duty (or function) as a Starfleet commander, to that presented by a hypothesized Klingon counselor or Berellian engineer; “they’re just not suited for those positions.”|
|Benzite||Benzar||"Coming of Age", "A Matter of Honor" (TNG)|
|Benzites are a humanoid race from the planet Benzar, and members of the United Federation of Planets.
Benzites possess smooth, hairless skin; it may range in color from bluish-purple to green-blue. A thick protrusion of the Benzite skull extends down over the face, displaying a prominent nasal lobe and brow. Two fish-like barbels droop down from above the upper lip. Benzites are highly resistant to poisons and other noxious substances. They can digest and derive nutrition from almost any organic compound. All Benzites from the same geostructure are physically similar, so much so that they are indistinguishable to a non-Benzite.
|Betazoid||Betazed||"Encounter at Farpoint" (TNG)|
|The Betazoid are a humanoid species, originating from the planet Betazed. They are telepathic and are members of the United Federation of Planets. Star Trek: The Next Generation features Counsellor Deanna Troi, a half-betazoid half-human, as a major cast member and part of the bridge crew. She is featured in almost all TNG episodes and movies, and there are several episodes that focus on the Betazoid people. These include shows with her mother, Lwaxana Troi. Her romantic interests, family, and personal life are plot elements in many Star Trek: The Next Generation episodes over the course of the series. Episodes usually feature Troi using her telepathic abilities to help the crew better understand enemies and allies.
Customs: The word Imzadi, meaning 'Beloved' is often used between a Betazoid and its soulmate, whether they are of the same species or not. Betazoid weddings are conducted with the bride, groom, and several participants completely naked, and the newlyweds possibly remain so for the duration of the honeymoon(TNG episode "Haven", novel "The Persistence Of Memory". A Betazoid woman's sex drive quadruples(at the least) when she reaches a certain age(TNG episode "Manhunt"). See also Category:Betazoids
|Bolian||Bolarus IX||"Conspiracy" (TNG) |
|Bolians are humanoids with blue skin and a small ridge running from the back of their heads to their noses. They were named after a regular Star Trek director, Cliff Bole. As an in-joke there have been references to the "Cliffs of Bole" on their planet. Neelix remarks that malfunctioning toilets will hit the Bolians especially hard, and during medical examinations 24th century doctors will commonly ask if a human patient has had sexual relations with a Bolian.
The Bolians have been active members of the Federation since 2320. Aside from contributing to the ranks of Starfleet they have a delegation within the Diplomatic Corps. In 2366, the Bolian government was maintaining an uneasy truce with the Moropa (TNG: "Allegiance").
The Bolians are known to make a crystal steel that is highly prized. They also own and operate the famous Bank of Bolius. In 2373, the Bolian government authorized the Ferengi Gaming Commission to manage their gambling emporiums.
During the Bolian Middle Ages the Bolians developed the medical philosophy known as the "Double Effect Principle" about euthanasia. This form of assisted suicide states that while euthanasia has the effect of relieving suffering it also has the effect of causing death. Bolian marriages often involve more than two members. Any additional spouse is referred to as a "co-husband" or "co-wife", respectively. Bolian blues is a highly appreciated musical genre among Federation species.
|Borg||Unknown||"Q Who?" (TNG) |
"The Best of Both Worlds" (TNG)
"I, Borg" (TNG)
|While actually encountered in the Enterprise episode "Regeneration", the Borg were not truly identified as the single greatest threat to the Federation until the events of The Next Generation episode "Q Who?".
The Borg were discovered to be a group without individuality, where every member is a part of a collective consciousness in an attempt to achieve perfection. They assimilate any species they come into contact with for either biological aspects (for example, Talaxians would be assimilated for their dense physical structure, useful for producing strong, resilient drones) or technological aspects (a species which has developed advanced engines or weaponry would be a sufficiently desirable target for assimilation) all in an attempt to further improve the overall perfection of the Borg as a whole.
The Borg have encountered and assimilated thousands of species, quantity most notable by their designation of Species 8472, although more may have been added to the total since that encounter.
The Borg are not so much a species, as a collection of species. In their assimilated state, most races are altered or augmented with cybernetic enhancements which make them all look similar, or at least instantly identifiable as Borg, making them a pseudo-species.
Encounters with the Borg have varied in type, from the disastrous defense of the Wolf 359 system ("The Best of Both Worlds"), in which many Federation ships were lost, the successful repelling of two Borg cubes from Sector 001 on two separate occasions ("The Best of Both Worlds" "Star Trek: First Contact") and the infiltration, usage of and destruction of a Borg transwarp hub (a critical part of their interstellar menace) by the USS Voyager ("Endgame").
|Breen||Breen, Alpha Quadrant||"Season 7 (1998–99)" (DS9)|
|The Breen are a mysterious race who joined the Dominion during the Dominion War.|
|Bularian||Unknown||"Journey's End" (TNG) M|
|In the beginning of Act 1, Captain Picard has set down a few items upon the conference room table in anticipation for Admiral Nechayev's arrival. Riker then says to the Captain, "Earl Grey Tea... watercress sandwiches... Bularian canapés... Are you up for a promotion?"|
|Bynar||Bynaus, Beta Magellan system||"11001001" (TNG)|
|Bynars operate in pairs and are interconnected with a master computer on Bynaus.|
|Race||Home Planet||Episodes M = Mention Only|
|Cardassian||Cardassia Prime, Alpha Quadrant||"The Wounded" (TNG)|
|The Cardassians are enemies of the United Federation of Planets and are mentioned in Star Trek: Deep Space Nine, Star Trek: The Next Generation, and Star Trek: Voyager. They have noticeable ridges along their foreheads and necks and a crest on their foreheads, earning them the nickname, Spoonheads. Their government is a military dictatorship.|
|A race of fluid shapeshifters, who founded the Dominion by genetically engineering organisms to operate the military and logistics. These organisms call them the Founders. The Founders refer to most humanoid species as "solids"|
|Race||Home Planet||Episodes M = Mention Only|
|Denobulans||Denobula, Alpha Quadrant||"Broken Bow" (ENT)|
|Denobulans are a Humanoid species who hail from the planet of Denobula of the Denobula Triaxa system. Denobulans only require 144 hours of sleep per year although some Denobulans, such as Doctor Phlox of the Enterprise NX-01, can sleep as little as 48 hours per year. It is customary for adult Denobulans to have three spouses each. Denobulans also have ridges running their forehead, cheeks, and spine.|
|Douwd||Unknown||"The Survivors" (TNG)|
|Immortal energy beings with vast powers. Only one is known to exist, choosing to live alone in human form on the planet Delta Rana IV. That one committed xenocide against the Husnock.|
|Race||Home Planet||Episodes M = Mention Only|
|Edosians (aka Edoans) are a race of sentient tripedal beings. Edosians have an orange complexion, two yellow eyes, three arms and three dog-like legs. Navigator Lieutenant Arex was introduced in Star Trek: The Animated Series, but his planet of origin, Edos, was mentioned only in background material. Passing references to Edosian flora and fauna have been made in episodes of Star Trek: Deep Space Nine and Star Trek: Enterprise. In some tie-in novels and short stories, Arex is mentioned as actually being a Triexian, with the Edosians being a near-identical race.|
|El-Aurian||El-Auria, Delta Quadrant||"Rivals" (DS9)|
|El-Aurians (referred to as a Race of Listeners by Dr. Tolian Soran, the El-Aurian antagonist in Star Trek Generations) are a humanoid race first introduced in the second season of Star Trek: The Next Generation with the character Guinan. The species was named in the Star Trek: Deep Space Nine episode "Rivals".
El-Aurians appear outwardly identical to humans, and have a variety of ethnic types, with both dark- and light-skinned members of the race being shown on various Star Trek movies and television episodes. They can live well over 700 years. They are considered a race of listeners and often appear patient and wise.
El-Auria, the El-Aurian homeworld, was located in the Delta Quadrant and was destroyed by the Borg in the mid-23rd century. Few survived, and those who did were scattered throughout the galaxy. Some of the refugees came to the United Federation of Planets.
At the start of Star Trek: The Next Generation, the Ferengi are considered a mysterious race who care only about profit. They feature as major characters in Deep Space Nine.
In a 1967 episode of the original Star Trek, Kirk fights with this lizard-like alien in the episode "Arena".
In the Star Trek science fiction universe, the Hirogen were a violent Delta quadrant species encountered by the USS Voyager. The Hirogen culture is based around the practice of hunting other sentient species whom they regard as "prey". They are humanoid, but considerably larger than humans.
The Jem'Hadar are characters in the TV series Star Trek: Deep Space Nine, first introduced in the episode "The Jem'Hadar". They are the shock troops of the powerful Dominion located in the Gamma Quadrant. Genetically engineered for strength and resolve, they are also short-lived and believe that "victory is life." They are bred to perceive the Founders, enigmatic shape-shifters who rule the massive Dominion, as gods and are incapable of harming them. The Jem'Hadar are noted as being able to camouflage themselves with surroundings, and are dependent upon the drug Ketracel White, a substance made and distributed by the Founders as a means of control. The Jem'Hadar's numbers are unknown, but they are produced by the thousands as needed.
Conceived as "more than just another fearsome alien", the Deep Space Nine makeup department searched for concepts depicting "toughness and resiliency" in the design of the Jem'Hadar. The final design was based on a rhinoceros, with some added ceratopian traits. Originally designed on the premise that they were all clones, the first Jem'Hadar seen onscreen were all made to look identical to one another, though as they became more deeply woven into the storylines, each Jem'Hadar was given a distinctive look.
The Kazon aliens were introduced on Star Trek: Voyager.
The Kelpiens lived on the terrestrial planet Kaminar, the planet from which Commander Saru hailed in Star Trek: Discovery. The Kelpiens were suppressed by the Ba'ul for many generations, a race who used their technological superiority to feast upon the Kelpien people and prevent them from experiencing Va'Harai, and gaining greater consciousness. In S2E7 of Discovery, "Light and Shadows", the Kelpiens, with the help of an energy source associated with the Red Angel, all experienced Va'Harai, and lost their innate fear of the Ba'ul. Thereafter with a stated plan to attempt to live in peace with their former tormentors.
The Klingons are a warrior race.
A cat-like race introduced in Star Trek: The Animated Series. This episode was an adaptation of a Larry Niven "Known Space" short story ("The Soft Weapon")
Kzinti society is a male dominated race of warriors (they prefer to use the term "Heroes") led by the Patriarch. Kzinti Heroes have much in common with Klingon warriors, in that they highly value courage, fighting prowess, and consider personal honor of highest priority. The one racial "flaw" that Kzinti have is overconfidence, which manifests itself in a tendency to attack before they are truly ready. This is because they believe that combat, with the removal of all challenge and risk (i.e. certain success), lessens the honor gained in battle. Kzinti Heroes place great pride in the scars they receive in battle, they also respect valiant and fierce opponents of other races, ensuring the bodies of these impressive alien warriors are stuffed and placed on honorable memorial display on Kzin, (the Kzinti home world).
Kzinti male are larger than their more docile females and humans. They somewhat resemble a bipedal, barrel-chested, tiger-furred "tabby". Their tails are naked (rat-like) and their ears have spines (resembling a section of a parasol).
A race native to the Delta Quadrant with a lifespan of only nine years.
Further characteristic: Bone ears and various psychic mind abilities.
The Organians are incorporeal energy creatures ("pure energy, pure thought") with no precise physical location in the universe. After the climax of the episode "Errand of Mercy", Spock comments that they are "as far above us on the evolutionary scale as we are above the amoeba." They assumed humanoid form to "interact" with the Federation representatives and the Klingons. They render all weapons belonging to the hostile parties inoperable through extreme heat, and then vanish.
The Organians were a race of beings who had evolved to a point of being pure conceptual beings, essence of thought with no corporeal bodies. In some ways they were similar to Q for power levels and abilities. In the novel Q Strike, the Organians appear to observe a battle between members of the Q Continuum and other seemingly omnipotent beings from the Star Trek universe. The original Q identifies them after being asked by Captain Jean-Luc Picard who they are, and is rather dismissive, remarking that "compared to their code of noninvolvement, your Prime Directive is practically an incitement to riot."
The Organians also appeared on Star Trek: Enterprise in the episode "Observer Effect," where they observed members of the crew infected with a silicon-based virus to decide whether or not they should make first contact with humans. They did not technically appear onscreen; they only manifested themselves by possessing the bodies of several members of the Enterprise crew.
Orions are a green-skinned, humanoid alien species in the Star Trek universe. An Orion was first portrayed as an illusion in the original Star Trek pilot, but wasn't seen in the broadcast series until this original pilot was incorporated into a two-part episode (episodes 11 and 12) in the first season. Orions have also been portrayed in Star Trek: The Animated Series, Star Trek: Deep Space Nine, Star Trek: Voyager and Star Trek: Enterprise. Rachel Nichols played Orion Starfleet cadet Gaila in the 2009 Star Trek film.
The Pakled are a species of space-faring humanoids who obtain technology from other races (rather than developing it themselves), often through trickery. They first appeared in the TNG episode "Samaritan Snare", where the Pakled ship Mondor feigned being in need of repairs. After Chief Engineer Geordi La Forge transported to the Mondor and completed repairs, the Pakled captured him and demanded weapons technologies. The Pakled do not appear again, but are mentioned in the TNG episode "Brothers" as the Pakleds inadvertently having rescued Data's brother Lore, who was beamed into space at the end of "Datalore". They appeared again in Star Trek: Lower Decks Season 1 episode No Small Parts as the antagonists. The Pakleds having upgraded their ships using scavenged technology from dozens of species, destroy the U.S.S. Solvang, and cause serious damage to the U.S.S. Cerritos, before being chased away by the Cerritos and U.S.S. Titan commanded by Captain William T. Riker.
Q is the name of a continuum and members of the continuum.
Romulans are humanoid extraterrestrials that appear in the Star Trek television series, where members of their race often serve as antagonists.
They prominently feature in the film Star Trek: Nemesis.
Remans were a humanoid caste related to the Romulans, forced to live as slaves under the Romulans and work in the hazardous dilithium mines on Remus. They also prominently feature in Nemesis.
A race from T-Rogoran Prime in the Gamma Quadrant, subjugated by the T-Rogorans to be slaves in the Dominion. Skreean leaders are women; men are considered too emotional to lead. Their legends say they will one day find a home, Kentanna, 'a planet of sorrow where the Skreeas will sow seeds of joy'. Four refugees, a vanguard of 3 million, sought asylum on Bajor, believing it to be Kentanna, but were turned away. Settled on Draylon II in the Alpha Quadrant. (Deep Space Nine episode 430; star date 47391.2)
Once members of the neo-luddite race the Ba'ku, the Son'a were exiled from their home planet by their fellows for trying to overthrow the leadership and embracing more advanced technology. Now separated from the rejuvenating properties of the Ba'ku planet, they attempt to avoid death through medical procedures. The Son'a use technology, including weaponry, banned within the Federation. However, in 2375 the Federation allied with the Son'a to take advantage of their technology to gather rejuvenating 'metaphasic particles' emanating from the rings of the Ba'ku planet, which is in Federation space. After the operation, which involved the forced relocation or genocide of the Ba'ku, was called into question and stopped by the crew of the Enterprise, a number of the Son'a reintegrated into the Ba'ku population. Others later joined the Dominion. The Son'a have subjugated two peoples as their slaves: the Ellora and the Tarlac.
The Tellarites first appeared in "Journey to Babel". (They have an odd facial appearance, represented by the actors wearing converted pig masks.) Culturally, they are known for their love of arguing and blunt, forceful speech, what most other cultures would consider rude; if Tellarite speech is answered in kind, they will typically consider it an honor. A Tellarite also appears in "Whom Gods Destroy" and "The Lights of Zetar" and in the animated episode "The Time Trap."
Tellarites did not appear in the TNG-era shows, but on Enterprise they are a major part of several episodes, becoming one of the founding species of the United Federation of Planets. They also appear in Discovery, in which Gorch, a Tellarite Starfleet admiral, is depicted. The animated series Lower Decks depicted a Tellarite captain in the episode "Moist Vessel."
The Thasians are a psionically powerful, non-corporeal species, native to the planet Thasus. Until the 23rd century, the Federation had never encountered the Thasians and thus believed them to be a myth. They appeared in "Charlie X" on the Original Series.
The Tholians are an extremely xenophobic, non-humanoid hermaphroditic species with a propensity for precision. They first appear in the original series episode, "The Tholian Web", where Spock makes the remark when fired upon by the Tholians: "The renowned Tholian punctuality". Tholian biology required high temperatures around 480 Kelvin (207 °C, 404 °F). They could tolerate lower temperatures for a brief period of time; if they were exposed to temperatures around 380 Kelvin or less, their carapace would crack. This was painful or distressing; a Tholian subjected to such a temperature regime could be coerced to cooperate. In temperatures even lower, a Tholian would freeze solid and shatter. (ENT: "Future Tense", "In a Mirror, Darkly")
Humanoid species that are distinct in that they are a symbiotic species. The outward appearance is the host. The symbiont is revered and passes from host to host carrying all the memories, skills, and experiences of each prior host. Trill symbionts are also capable of joining with human hosts. (Star Trek Discovery - S03E03)
The Trill made their debut on television in the Star Trek: The Next Generation episode "The Host" (May 11, 1991), and were further developed as the species of successive main-cast characters of the television show Star Trek: Deep Space Nine which made its debut on television with the two-part opener "Emissary" (broadcast January 3, 1993). This species was also briefly represented as a holonovel character corresponding to Ensign Harry Kim on Voyager in "Author, Author" (April 18, 2001).
Trill have been studied in analysis of the biology of Star Trek, especially in regards to the symbionts.
There are two contrasting concepts for Trill. One is that the symbiont is essentially an alien person; however, the joined Trill still mixes the original person with the memories and some of the personality of the symbiont. Only a small percentage of Trill are joined, and being accepted for the process is considered an honor. For joined Trill, a symbiont's memories and to some extent personality are a synthesis with the existing Trill's personality. Joined Trill have been studied in the philosophies of Star Trek, in particular whether a person is essentially the sum of their memories (the philosopher Locke's "memory theory"). This concept was explored in the Star Trek:Deep Space Nine television episode "Dax". (see Personal identity § Locke's conception)
The contrasting philosophy of the symbiont is called "functionalism" according to Star Trek and Philosophy: The Wrath of Kant, in which people are defined by their actions as opposed to memories. The symbionts have been dismissed as "just memories" rather than a true person, although in other cases they are described as a "sentient symbiotic organism".
Vorta are a member race of the Dominion. A small subspecies made primarily of genetically cloned humanoids. Vorta were created by the Dominion to act as governmental administrators, field commanders, scientists and diplomats. They have direct authority over the Jem'Hadar and are tasked with dispensing rations of Ketracel White to them.
Vulcans are a warp-capable humanoid species from the planet Vulcan, widely known for their logical minds and stoic culture.
|Star Trek race|
|Language||Various native languages|
|Affiliation||Sphere Builders (22nd century), United Federation of Planets (26th century)|
|Leader||Governed by the Xindi Council|
The Xindi // is the collective term for six fictional races in the science fiction television series Star Trek: Enterprise. The entire third season, broadcast in 2003 to 2004, centered on this group of previously unknown aliens. They are native to the planet Xindus in a region of space known as the Delphic Expanse. They consist of five species resembling familiar Earth animals (a rarity for alien races in Star Trek) and a sixth resembling humans. At first they appeared as violent enemies wanting no interaction with humanity, but common ground gradually emerged as the crew of the Enterprise discovered that the Xindi were being manipulated into this enmity by the Sphere Builders. Some Xindi became important recurring characters as the 24-episode story arc unfolded.
During the thirteenth live-action film in the series, Star Trek Beyond, the Xindi were mentioned along with the Romulans as aliens that humanity fought wars against in the years leading up to the formation of the Federation. Their defeat and eventual alliance was the cause behind Edison's mutiny against the Federation, leading him to become the villain Krall.
The Xindi's presence was established in the second-season finale of Star Trek: Enterprise, "The Expanse", in which the Xindi launched a probe that attacked Earth in April, 2153, killing seven million people in a strip of destruction stretching from Florida to Venezuela. They appeared again in the third-season premiere, "The Xindi", to play a major role in the primary story arc of season three.
The Xindi are a collective of six intelligent species which evolved simultaneously on the same planet (Xindus). Despite the radically different appearance of all six species, they all share identical ridges on their cheekbones, and have very similar DNA. All six of these species were involved in a war lasting about 100 years and ending in the 2030s. Alliances among the Xindi species were forged and changed continuously throughout the war, so much that 50–60 years into the war, most Xindi forgot what started it. However, everyone remembered how it ended. In an act of desperation, the Insectoids and Reptilians detonated several charges beneath the eight largest seismic fissures of the geologically-unstable planet Xindus, leading to its destruction and ultimately the extinction of the Avian race.
After the war, the Xindi scattered throughout the Expanse into several colonies. As a whole, they have a passionate desire to establish a new homeworld and unify all Xindi, but differ greatly on how to accomplish this and on who should hold the ultimate reins of power. The Xindi then spent the early part of 2153 deciding how to confront the threat of humanity and planned a biological weapon based on the human genetic profile. This was ultimately rejected by the Xindi Council (the Reptilians went along with the bio weapon but were eventually foiled) and so they worked on a weapon to destroy Earth. (They technically succeeded, however the timeline in which this occurred was undone.)
The Xindi were actually pawns in the Temporal Cold War, as interference in their history began shortly after the ending of their civil war, with the appearance of a trans-dimensional alien race, who guided them to new homelands and resources. The Xindi came to revere these "Guardians", whom they later understood to be the same species as the "Sphere Builders". These aliens were also similarly revered by the Triannon, who believed that deities, who they called "The Makers," constructed the spheres to transform the expanse into a paradise. This led to a devastating religious civil war, as seen in the episode "Chosen Realm".
The Xindi were also informed by the Guardians, at least as early as 2152, that they would be victims of a genocidal attack from humans in the 26th century. Following their guidance, the Xindi launched a pre-emptive test strike on Earth as a precursor to a devastating second attack. In Daniels' timeline, Xindi crewmen serve in the Federation in the 26th century, in a battle with humans and Xindi against the Sphere Builders. With the help of Captain Archer's evidence of the future cooperation, the Xindi Council began to split over the issue of whether the Guardians were the real enemy or not. The split widened when Reptilian Council Member Dolim killed Primate Council Member Degra.
With the help of the Guardians, the Reptilians and Insectoids then took control of the finished Xindi weapon and set on a course for Earth, thus triggering a new civil war. A combined fleet of Arboreals, Primates and Aquatics pursued the weapon. En route to Earth, a rift appeared in the Reptilian-Insectoid alliance when the Insectoids proposed delaying the destruction of Earth in light of Archer's revelation about the true nature of the Sphere Builders. The Reptilians, determined to see the task completed, eliminated the accompanying Insectoid vessel. Arriving near Earth, an Andorian vessel, commanded by Shran, suddenly destroyed the Reptilian vessel, allowing humans to board the Xindi weapon and destroy it. At the same time, Enterprise was able to destroy the entire sphere network, stopping the spatial anomalies. With the Sphere Builder threat ended, the Xindi Council reconvened (the Reptilians were eventually convinced to return), and the Xindi abandoned their belief in the Guardians, and their hostile intent toward humans.
Xindi-Aquatics resemble Earth sirenians, swimming underwater and speaking through echolocation. Aquatics have a reputation for taking a very long time to make a decision, but are more readily convinced by visual evidence. The Xindi have a saying, "It's easier to count the stars than it is for an Aquatic to reach a decision." The appearance of the Aquatics in the series was inspired by the Mosasaurus.
Even though the Aquatics are peaceful, they have a strong military. Their warships resemble large Earth manta rays and are filled with water. However, there is at least one section of the ship that is sealed and filled with air for land-based races. This room also has a window so the visitors can communicate with the Aquatic crew. Aquatic vessels can emit a field that disrupts targeting scanners. This can also be applied to protect other ships. However, their ships are very slow and cannot travel much faster than Warp 2. Aquatic ships also carry extremely powerful weapons and are more than a match for Insectoid and Reptilian ships. Aquatic warships are huge and one of them was depicted carrying the Enterprise NX-01 to Earth inside a chamber within the vessel after the Xindi weapon was destroyed.
Xindi-Arboreals are covered with hair, and resemble Earth sloths. They run kemocite-production facilities throughout the Delphic Expanse. Gralik, a Xindi-Arboreal, gave Degra a shipment of impure kemocite, to sabotage production of the Council's weapon prototype. They have shown the least interest in destroying humanity. Arboreals are also afraid of the water. They are well known as scientists. Jannar was a friend of Degra and an ally of Captain Archer.
Xindi-Avians were birdlike Xindi with the ability to fly, although all that is ever seen of this species is a single skull, identical to that of a giraffe. They once darkened the skies of Xindus, the Xindi homeworld. They are thought to be extinct since the Reptilians and Insectoids planted explosives that destroyed the Xindi homeworld after the Hundred-Year War. The Avians, having primitive technology, could not leave the planet and were wiped out. Because of this, the Reptilians say that their lair, in which the Xindi Council now convenes, has a "stench of failure."
Xindi-Insectoids resemble a cross between six-foot Earth praying mantids, flies and ants. Insectoids have an average life span of 10–12 years. They reproduce asexually by laying eggs, which take about a week to mature. Egg sacs are suspended from ceilings, and tubules connected to them spray chemicals that cause passers-by to reverse-imprint on the hatchlings, protecting them as a parent would. Hatchlings are so important to Insectoids that hatcheries aboard starships are heavily shielded. As seen in episode "Hatchery", the Insectoid crew will sacrifice themselves to preserve their unborn offspring.
They speak a clicking language, of which there are 67 known dialects. Insectoid iconography is radically different from that of other Xindi. Insectoid personal names get longer with age. Insectoids have a reputation for rushing into decisions. Insectoid starships are designed differently from other vessels. They don't have one area designated for bridge duties; command functions are distributed throughout the ship. Insectoid chairs and assault vehicles are designed for Insectoid anatomy and not humanoids. They have a long-standing alliance with the Reptilians and together they destroyed the Xindi homeworld after the Hundred-Year War.
Xindi-Primates resemble Earth humans and have a similar brain structure to the Xindi-Reptilians. They were one of the first Xindi species (including the Reptilians) to be informed of the "threat" posed by humanity. Degra, a Xindi-Primate, was assigned to develop the weapon which was to destroy Earth. In late 2153, the crew of the Enterprise boarded and studied a Primate's vessel and interrogated the crew. In the episode "Stratagem", Archer learned from Degra that a colony of Primates resides on Azati Prime, where the weapon was being constructed. Like humans, Xindi-Primates have differences in skin tone. The chairman of the Xindi council was a Xindi-Primate.
Xindi-Reptilians resemble a cross between several Earth lizards. This species is responsible for a preemptive attack on Earth in 2153. Aided by trans-dimensional beings, the Reptilians also traveled to 2004 to collect blood samples for their bio-weapon in the future but were foiled by Jonathan Archer and T'Pol. Reptilians prefer to be low to the ground, as opposed to high-rise buildings. They use weapons with regenerative biometric power cells that overload if another species tries to use them. They use thermal chambers on board their ships to keep their energy. They are the most aggressive race of Xindi and seem to be more interested than the other races in destroying Earth. The military leadership of the Reptilians appear to be obsessed with eugenics. The Xindi-Insectoids are the race that the Reptilians are closest to. Along with the Insectoids, they are responsible for the destruction of the Xindi homeworld. The attack squadrons seen at Azati Prime consisted of two Reptilian ships and two Insectoid ships. Commander Dolim was the Xindi-Reptilian representative on the Council.
The Xindi Council is the joint governmental body of the Xindi races, as seen Season three of Star Trek: Enterprise. The Council was formed after the destruction of the Xindi homeworld Xindus in the 2030s. It consists of two representatives of each of the Xindi species, and was formed to find a new homeworld for all the Xindi races. However, although they found a few suitable planets, they could never agree on a final choice. The Council chamber is located on a planet 15.6 light-years from Azati Prime. The land-based races sit at a large round table in the center of the room, while the Aquatics look on from a large tank adjoining the chamber by a window. The chamber has built-in equipment for holographics and a viewscreen for telemetry. The chamber itself was actually a stronghold built by the Xindi-Avians before they were wiped out.
Circa 2152, the council discovered that humans were going to destroy them in four hundred years. In a panic, they assigned the Primate scientist, Degra, to construct a weapon to destroy Earth. After a number of disagreements, the Council was dissolved. In order to do the Sphere Builders' bidding, the Reptilians and Insectoids broke away from the Primates, Arboreals, and eventually the Aquatics. Civil war ultimately broke out when Commander Dolim killed Degra. After Dolim was killed, the Sphere Builders were discredited, the super-weapon destroyed, and the Council reconvened. The names of council representatives as revealed in "The Council" were:
- Arboreals: Jannar
- Aquatics: Kiaphet Amman'sor
- Insectoids: unknown- (most Xindi Insectoid names are unpronounceable by humans; called "Shrest" in the novelizations)
- Primates: The Chairman, Degra
- Reptilians: regimental commander Dolim
