Aaamazzarite;
Aaamazzarites, also called Therbians, are a hairless species with pale yellow skin. Aaamazzara (Therbia), orbits Epsilon Serpentis in the Alpha Quadrant. Everything on the planet is bio-chemically produced from their mouths, including clothing and furniture. They are members of the United Federation of Planets.
To date, Aaamazzarites have only appeared in Star Trek: The Motion Picture. Nothing has been revealed about them in dialogue, so their backstory is only considered semi-canon.
Aenar;
Aenar, a humanoid species in the Star Trek fictional universe. Along with the Andorians, they inhabit the world of Andor (Andoria). They resemble the Andorians in physical appearance; they have white hair and antennae atop their heads. 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. 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 a utterly separate species.
The Aenar population is approximately 1,000 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.
The Aenar were first seen in the episode "United" on the television series Star Trek: Enterprise.
Based on Talla, Shran's daughter from "These Are the Voyages...", it has been speculated that hybrids of an Andorian and an Aenar would be a greenish color, to explain the Green Andorians seen in Star Trek: The Next Generation.
Angosian;
Angosians is a fictional race in the television series Star Trek.
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.
Non-canon: a novel trilogy, Star Trek The Q Continuum shows that the Angosians have had some success in later efforts to reintegrate the soldiers, as one now serves on the Enterprise E.
Antedean;
Antedeans are an ichthyohumanoid species which resemble fish. This race was first encountered in the episode Manhunt.
The Antedeans home planet is Antide III and while a member of the United Federation of Planets they seldom receive visitors and so 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. Interestingly enough, while a space-going race, space travel is also quite traumatic for the Antedeans. In order for individuals to deal with this problem they bring on a half-lidded catatonic state while in space flight. To awaken from this state takes several hours. Once awakened from the sleep Anteadeans 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 explosives
Antican;
The Anticians are a species of aliens from Star Trek. They are slightly cat-like with 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 Antician diplomatic team supposedly cooked and ate a member of the Selay delegation.
Arcadian;
Arcadians are a species in the fictional Star Trek universe.
They have large, round, doll-like heads and have hair on the left & right sides of their heads with none in the middle. Arcadians are members of the United Federation of Planets with a representative on the Federation Council. They joined at least as early as the 2280s.
To date, an Arcadian has only been seen in Star Trek IV: The Voyage Home.
Arcturian;
Arcturians are a species in the fictional Star Trek universe known for their clones.
Arcturian clones have the appearance of melted skin and hail from the densely populated world Arcturas, presumably in the Alpha Centauri system. They provide the backbone of the Federation infantry, as billions of new soldiers can be cloned overnight. It is noteworthy that Arcturians were never mentioned during the Dominion War.
To date, Arcturians have only appeared in Star Trek: The Motion Picture. Nothing has been revealed about them in dialogue, so their backstory (by Fred Phillips and Robert Fletcher) is considered semi-canon.
Axanar;
The Axanar are the first extraterrestrial race befriended by Earth people aboard the NX-01 Enterprise. Archer and his people rescue Axanar aboard a ship that has been disabled, 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 commendations is the Palm Leaf of Axanar Peace Mission. This would be a confusing matter, as it one implied possibility is that the Axanar still were not Federation members and that the Federation took part in an Axanar mission of peace somewhere. Alternatively, the Axanar at a later time experienced anarchy or a civil war, and the Federation was able to assist in resolving it. Either way, Starfleet personnel were involved in a peace mission, and Kirk was among them.
Bajoran;
Humanoid race, distinguished outwardly only by extra wrinkles at the bridge of the nose, have wandered the galaxy and settled on various worlds ever since their homeland was occupied by Cardassians 40 years previously (circa 2328).
According to custom their family name goes before their own. They are very spiritual and believe in the existance of higher dimension beings that dwell in the Wormhole, the so-called Prophets. The oposite of the Prophets are the Pai-reids (flame creatures) that were outcasted from the Wormhole due to their wish to interfere with the way of the corporeal world. The Pai-reids are told to live in the Fire Caves on Bajor Prime.
The depth and complexity of Bajoran spiritual beliefs has been at the core of their ability to survive 40 years of suffering at the hands of the Cardassians. To the Bajorans, the land and the people who live on it are one and the same. Bajorans are led by both a spiritual leader (Kai) and by a provisional government.
The ancient Bajorans had a tremendously rich and developed civilization complete with architecture, art, philosophy and even some technology before human beings on Earth became bipedal. Many Bajorans have joined Starfleet despite their home planet of Bajor still being in recovery from the Cardassian occupation, while others prefer to work with the Federation from within the Bajoran system.
Since the discovery of the wormhole near the Bajoran homeworld on stardate 46379.1, the Bajorans have enjoyed an increase in political power in their sector, but only after decades of victimization during the Cardassian occupation of their planet. Some Bajorans have a unique and personal insignia designed for themselves. Major Kira knew the famed Linalis' on sight. School years are organized by age "levels," and perhaps even in the refugee camps they offered art to youngsters as young as age 4. Bajor's tradition of art and architecture was strewn around countless planets before the occupation. Its science and space programs were back on track soon after the occupation: at least one probe was sent to scan planets and life signs in the Gamma Quadrant.
Bandi;
The Bandi are a humanoid species native to the planet Deneb IV in the Alpha Quadrant. The Bandi appealed to the United Federation of Planets for membership in 2364 but were rejected due to the fact that they had captured and enslaved an alien life form. The Bandi's first appearance was in the Star Trek: The Next Generation first episode "Encounter at Farpoint".
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."
Berellian;
Berellians are an alien race referred to once in the Star Trek: The Next Generation episode "Redemption".
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, implies that, as an android, Data is out of place commanding a Federation starship. Hobson compares the apparent dichotomy to that posed by a Klingon counselor or a Berellian engineer; "they're just not suited for those positions."
Betazoid;
A Federation race basically humanoid except for the solid-colored dark pupils and mental power of telepathy within the race. They also have varying empathic links to other races.
Their empathic/telepathic contact leads to a natural trait of complete honesty, somewhat troubling to outworlders when practiced fully. The telepathy is not inborn but almost always comes on with adolescence. There are also cases of over-empathic abilities, and those who suffer from such extremes must be counseled and trained to avoid insanity, but are almost always affected throughout their life.
Betazoids are actually uncomfortable around those, like the Ferengi and Breen, whose minds they cannot read. Similarly, the minds of animals can be a bit frightening to them, and they tend to prefer smaller animals. Their mind contains the paracortex, their telepathic lobe, which is highly capable of recovery from injury, and includes the "metaconsciousness," or a trauma filter. Psilosynine is the neurotransmitter involved. In addition, their REM sleep frequency is different than for most humanoids.
Betazoids practice an old style of marriage arrangement called genetic bonding, wherein children are promised to each other for marriage later by their parents. On the same note, Betazoids are known for their ability to love more than one person without losing their ability to love their mate, nor are they bound by their marriage customs. Because marriage is a celebration of the act of love to Betazoids, the wedding ceremony itself is traditionally conducted in the nude.
Childbearing is similar to humans, except the normal gestation rate for Betazoid females is ten months rather than nine. Betazoid women are not considered to be "matured" until they at least reach their forties in equivalent human years, which coincides with the timing of the female Betazoid "Phase."
Bolian;
The Bolians are a fictional alien race in the Star Trek universe. They are bald with blue skin, with a small ridge running from the back of their heads to their noses. They were named after a regular Star Trek director, Cliff Bole. Their home planet is named Bolarus IX, and 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 Principal" about euthanasia. This form of assisted suicide states that while euthenasia 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 apreciated musical genre among Federation species.
Breen;
The Breen are a species in the science fiction franchise Star Trek. They wear suits which generate an arctic environment inside them; this is because their homeworld is believed to be an arctic wasteland. They have never been seen on the show outside their suits. They established the isolated Breen Confederacy in the Alpha Quadrant and became a powerful ally of the Dominion of the Gamma Quadrant.
The Breen have established mining facilities consisting of Breen guards and kidnapped workers (from spaceships), such as Tora Ziyal, Gul Dukat's daughter.
The Breen suits are usually thought of as refrigeration suits, but some speculate that the Confederacy is a comfortable environment (from the Cardassian point of view). The helmet of the suit consists of a glowing green visual piece and a beak, which seems to suggest the Breen have an unusual facial structure. The Breen have no blood or any similar liquid circulatory system.
The Breen eat algae paste, which is probably the only plant life that grows in an arctic environment.
The leading representative of the Confederacy to the Dominion is the Thot (similar in rank to a General).
Although the Breen appear almost exclusively in episodes of Star Trek: Deep Space Nine, one Breen appeared as a hologram enhanced by the Hirogen in Star Trek: Voyager.
Briori;
The Briori are a fictional race of aliens, mentioned in the Star Trek: Voyager episode "The 37's", who routinely kidnap beings from worlds throughout the galaxy to be used as slaves. In the year 1937, the Briori abducted hundreds of humans from Earth and brought them to a world in the Delta Quadrant to use as slave labor. However, this proved to be short lived, as the humans revolted, killed the Briori, took their weapons and technology, and established a civilization on the planet. The Briori may be related to the Skagarans, another slave-owning race featured in an episode of Star Trek: Enterprise.
Bynar;
The Bynars are a highly intelligent species who have become almost machine-like due to a constant connection with their homeworld Bynaus's master computer. The Bynars first appeared in the Star Trek: The Next Generation episode "11001001", and were also mentioned by Phlox in the Star Trek: Enterprise episode, "Regeneration".
The Bynars are asexual beings roughly the size of regular Human adolescent. They have over-sized heads to make up for a large brain. The Bynar skin-tone is purplish in color. The Bynars are an official member of the United Federation of Planets. Due to the Bynars' total dependence on their master computer they have become so machine-like that their speech is essentially a form of binary code. Hive-like in nature, disconnecting a Bynar from the master computer or each other is near fatal. Due to this total interconnectivity, and their ability to speak in machine language, they are able to communicate at a rapid rate. So fast in fact that they require the aid of data buffers to be built into their clothing. It should be noted that, not surprisingly, the Bynars are known throughout the Federation for their skill with computers.
When a Bynar is born, a surgeon removes the infant's parietal lobe and replaces it with a synaptic processor.
Deltan;
In the fictional Star Trek universe, the Deltans are a closely humanoid species, probably Federation members. Only one confirmed Deltan has been seen on screen, Lieutenant Ilia in Star Trek: The Motion Picture, although the novelization of Star Trek II: The Wrath of Khan identifies at least one of the scientists on the Regula 1 space station as Deltan. Presuming she is typical of her species, Deltans (or at least female Deltans) are most notable for having bald heads. They have a limited telepathic ability, allowing them to stop another person from feeling pain by touching them. Deltans emit extremely powerful pheromones, provoking a strong sexual reaction in many other species. Although this article previously reported that this detail of Deltan pheromones existed only in non-canonical sources, the issue is addressed in Star Trek: The Motion Picture.
Ilia reported that her "Oath of Celibacy" was on record when she reported to Kirk. While the original theatrical release does not expand on this, later revisions include dialogue establishing that she is "as safe as any Human," and that she would never take advantage of a "sexually immature species". Deltan culture is also said to heavily emphasise sexuality - Roddenberry once said that to a Deltan, sex is like a handshake. Deltans in Starfleet were thus forbidden from engaging in sexual activity so as to limit their disruptive influence on other species.
Denobulan;
The Denobulan are a fictional humanoid race in the Star Trek universe. They were introduced in the Enterprise series. They originate from the planet Denobula Triaxa. Doctor Phlox is a Denobulan.
The Denobulans are humanoid with facial ridges. They have no need for sleep but they do hibernate for 6 days a year. When threatened, Denobulans can inflate their heads like blowfish to scare off predators. Denobulans are also expert climbers, thus making them suitable for exploring caves, canyons and other sheer rock formations.
Denobulans are polygamous, with each Denobulan typically having 3 partners that also have 2 other partners, creating a large social network. They have complex mating rituals, and they don't like to be touched. Denobulans usually don't have pets, and they abandoned television a long time ago. They believe that their real life is much more exciting. Despite their rather liberal views on sex, Denobulans are exceedingly modest when it comes to disrobing in front of others.
Denobulans used to be xenophobic, but they got over it and now enjoy contact with other species. They were once at war with the Antarans, a neighboring species. They established friendly relations with Earth at least before 2151.
Drayan;
Drayans are a xenophobic race from the Delta Quadrant. The crew of the USS Voyager in Star Trek: Voyager discovered the Drayan elders when the Delta Flyer crashed on one of the Drayan moons.
Drayans live on Drayan II, and have little to no contact with outside races. They have a very closed society, due to their species unique attribute of aging. It is uncertain how Drayans are born: They are born looking as if they are elderly, around the human age of 100. From there, they age backwards, growing younger in body as they grow older in wisdom and experience.
When they appear to be the age of a six-year-old human child (making them over 90 in Drayan years), they are shuttled over to one of the moons of Drayan II, where they essentially die. Their bodies disappear, leaving only their clothes behind.
Basically humanoid in appearance, Drayans have a coloured line down their forehead, the only visible mark that distinguishes them from humans.
Hirogen;
The Hirogen are a fictional race in the Star Trek universe. They are spacefaring and nomadic and featured in Star Trek: Voyager. Resident to the Delta Quadrant, the Hirogen are roughly technologically equal to Starfleet, though have a primitive social structure, where each pack is led by an "Alpha", with a "Beta" serving directly under him.
The Hirogen view all other races as prey, and make sport of pursuing what they deem worthy adversaries. With this in mind, some far-seeing Hirogen believe their society, which has broken up into a number of factions each engaged on their own hunts, has become too divided to survive in the hostile Delta Quadrant.
Hirogen are typically much taller than a human, perhaps seven to eight feet in size. They are powerfully muscular. It can be surmised that their close combat capabilities outstrip those of a typical Starfleet officer by quite a margin. Hirogen hunters of all ranks wear tough blue armour, generally with face masks. Before a hunt, all Hirogen hunters colour their faces with some type of war paint.
Hunter;
Hunters are a species who live in the Gamma Quadrant. They are part of the Dominion, serving as navigators and trackers. To hone their skills, Hunters engage in lifelong pursuit of another, related species, Tosk. Hunters value a long, challenging hunt, preferably ending in the Tosk's heroic death. If they manage to capture a Tosk alive, they will reluctantly take it back to their homeworld and subject it to ridicule and public display. Following a hunt which was briefly interrupted on Deep Space Nine, the Hunters declared it (and the entire Alpha Quadrant) off limits for future hunts.
Hunters respect and value the Tosk they hunt; to the Hunters, Tosk are the living embodiment of all that is noble and courageous.
Hur'q;
The Hur'q are a species that conquered the Klingon homeworld, Qo'noS (Kronos) about 1,000 years prior to the timeline of Star Trek: The Next Generation. Their name is the Klingon word for "outsider" and is probably not their own name for themselves. The Hur'q plundered Qo'noS, stealing the revered Sword of Kahless. They apparently originated in the Gamma Quadrant, and may have travelled through the Bajoran Wormhole to reach this part of the galaxy.
We've never seen a Hur'q on Star Trek, as they are believed to be extinct.
The Hur'q invasion of Qo'noS was said to be the first most serious threat to the Klingon people in their history, the second being the Augment virus (ENT Affliction)
Iconian;
The Iconians were a highly advanced ancient culture that was destroyed around 200,000 years ago by orbital bombardment that destroyed the surface of their planet, however some may have escaped through the gateway which is a dimensional transport that was used to travel interstellar distances instantaneously.
Iconia, the home planet of the Iconians is located in the Romulan Neutral Zone near Romulan space. It was discovered by the United Federation of Planets in 2365 by Captain Donald Varley of the USS Yamato.
The Iconians were also mentioned in Deep Space Nine. Benjamin Sisko and company assissted Jem'Hadar soldiers in destroying a second gateway. This episode marked the first appearence of the Vorta, Weyoun.
Karemma;
The Karemma are a humanoid civilization native to the Gamma Quadrant, and members of the Dominion. Similarly to many other Gamma Quadrant species, they have only made appearances in Star Trek Deep Space 9. In 2371, Federation agents onboard the USS Defiant, came together with First Minister Ornithar of the Karemma in an attempt to contact the Dominion. This appointment has been made by Quark, who worked as an ambassador of the Ferengi to the Dosi and the Karemma. (DS9: "The Search, Part I")
In 2372, a Karemma ship commanded by Hanok was intercepted by the Jem'Hadar while conducting trade relations with the USS Defiant. All of the ships entered the atmosphere of a gas giant, where the badly damaged USS Defiant was able to destroy the two Jem'Hadar attack ships and rescue the Karemma transport. (DS9: "Starship Down")
Kati;
The Kati are a humanoid species that live in the Delta Quadrant. They are a deeply spiritual people; shunning everything from entertainment to spicy foods. In their culture, males and females work separately. The Kati bathe with pure water only, and observe prayers eight times each day. The ritual greeting upon entering unfamiliar territory is to say "Travelers who have left the sanctity of their home and family, we welcome you to our home; our family." The Kati were featured in the Star Trek: Voyager episode "Someone to Watch Over Me."
Klaestron;
Klaestrons are an intelligent humanoid race from the planet Klaestron IV. The Klaestrons are first encountered in the Star Trek: Deep Space Nine Episode "Dax".
Klaestrons are distinguishable in appearance by an ear ridge that comes forward to the eye, raising the hairline over the ear. In Klaestron society, males and females are considered equals.
Kreetassan;
Kreetassans were one of the first races encountered by Captain Jonathan Archer and his crew on Star Trek: Enterprise. However, the contact did not go well: While being led on a tour of the ship, the Kreetassan delegation abruptly turned tail and left in a huff. The Enterprise crew quickly learned the reason: In Kreetassan culture, the simple act of eating a meal is viewed as an intimately private ritual, similar to mating. When the Kreetassans saw the Enterprise's mess hall, they were so mortified by the sight of many humans eating meals together, that the first contact between the two species was abruptly cut short. (episode "Vox Sola")
Later, the Enterprise visited the Kreetassan homeworld - inadvertently causing another incident when Captain Archer's dog, Porthos, relieved himself on a sacred Kreetassan tree. Captain Archer, to save face, was forced to perform an elaborate ritual of apology (mainly involving cutting pieces off the tree and arranging them in an intricate pattern) to the Kreetassan government. (episode "A Night In Sickbay")
Krenim;
The Krenim Imperium is a technologically advanced race in the Delta Quadrant. Their military revolves around temporal based weapons that distort the space-time continuum. Armed with Chroniton Torpedoes, Krenim Warships are able to take on even the most well armed vessels. Being out of sync with normal space-time, the these torpedoes can penetrate any conventional shielding. One example of the advancement of the Krenim is the Temporal Weapon Ship that was commanded by Annorax. With a single shot from its temporal core, the ship could alter history; destroying an entire species or a single molecule.
Ktarian;
Ktarians are an alien species native to the Alpha Quadrant. They are recognized by their catlike eyes and large frontal skull bones. Ktarians mature much faster than other species of their region of space - Naomi Wildman, half Ktarian, appeared to age at over double the rate of humans.
In 2368, a Ktarian plot to take control of Starfleet was uncovered when a mercenary named Etana Jol was captured while attempting to spread a mind-controlling device throughout the fleet. However, Etana was clearly not Ktarian, and may have been simply acting on behalf of a splinter group of renegades - this is supported by later episodes which describe the Ktarians joining the United Federation of Planets.
The seventh planet in the Ktarians' home star system is used by their race as a sacred burial ground - Ktarians will lay thousands of stones on the graves, each stone representing a special prayer.
Ktarian cuisine is also well known throughout the galaxy. Noted Ktarian desserts include the Ktarian chocolate puff and spice cake; Ktarian eggs are highly sought after as a breakfast dish.
Lurian;
Lurians are a large humanoid race known for their voracious appetites, perhaps due to the fact they have two stomachs.
Although little is revealed about the Lurian homeworld on the show, it was implied Lurians are usually found near the Hyundite Nebula.
The Lurian government is a monarchy.
A familiar Lurian character on Star Trek: Deep Space Nine is Morn. (He also happens to be the only Lurian we've ever seen.)
Ocampan;
Originally surface dwellers and the dominant species of their homeworld, the Ocampans exhibited phenomenal mental powers far in excess of any similar race in Star Trek canon. Their amazing mental abilities were offset, however, by their extremely short nine-year lifespan, less than that of dogs. (This is in marked contrast to the usual practice of making alien races longer-lived than humans.)
The development of the Ocampan race was interrupted when an exploratory vessel from another galaxy that chose to visit the Ocampan homeworld. The propulsion system of the intergalactic vessel caused an irreparable chain reaction in the atmosphere of the planet destroying the ability of the atmosphere to carry on a rain-cycle. According to Captain Kathryn Janeway, the planet's atmosphere was "completely devoid of nucleogenics." The intergalactic explorers upon realizing their mistake, took upon themselves the responsibility of taking care of the Ocampans. 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 a gigantic orbiting station. From this station, the "Caretaker" dutifully watched over the Ocampans, supplying every need and protecting them from every danger. As a result of this life of absolute ease, the Ocampans eventually stopped using their mental powers and due largely to their short lifespans, eventually forgot about them completely. Over time, the Ocampans became completely dependent upon the Caretakers for all necessities of life.
The Ocampans remained in this state until the only Caretaker remaining on the station began to die. This Caretaker reasoned that only his own offspring would be able to carry on his work of protecting the Ocampans, and so began a galaxy-wide search to find a genetically compatible race through which it might produce offspring. This search consisted of a long series of trans-galactic ship-jackings, which is how the Federation Starship Voyager came to be in the Delta Quadrant.
Trabe;
The Trabe were at one point a major power in the Delta Quadrant. They were brutal slave masters ruling over the Kazon race, until one day when the Kazon revolted. All Trabe technology and spacecraft - even their homeworld - were all stolen by the Kazon. The Trabe have been reduced to nomads, constantly pursued by Kazon fleets and unable to settle on any permanent planet for fear of being exterminated by the former slaves. The Trabe attempted, with Kathryn Janeway's assistance, to make an alliance with the Kazon in "Alliances", but were unsuccessful due to the Trabe's secret attempt to kill the Kazon majes.
Tzenkethi;
The Tzenkethi are spacefaring race of humanoids in the Alpha Quadrant. It is formed of several member star systems and is known as the Tzenkethi Coalation. The planet is called "Tzenketh". Ruled by autarch caste system. The principal change of government is via the "coup d'etat". A ferocious, fanatical, honorable, feline humanoid race. A persistent rumor in fanon is that the Tzenkethi are the same race as Larry Niven's Kzinti but no evidence has been found to support this.
