Emblem of the Breen Confederacy

The Breen were a species native to the planet Breen in the Alpha Quadrant. They were a notable secretive race, often seen as an unknown factor as even their allies were not privy to a great deal of information on the race. During the Dominion War the Breen government, the Breen Confederacy, allied with the Dominion, following the conflict they retreated back into their own space.



They were a Humanoid species that shared many of the same characteristics as Humans such as the same averages for height and build though this was a presumption. The common factor in all encounters was that the race were met within their sealed, refrigerated suits of armor that were designed to keep them comfortable in environments that did not match their needs.

While many races call the Breen cold blooded and heartless, some elements of this lie within their bodies which are in fact bloodless. This means that they required no form of central circulatory organ or heart. Some speculation made by xenologists believe that the Breen may be a silicon-based lifeform, but little evidence supports this theory.

The actual appearance of the species was that of walking sacs of ammonia and gelatin which are held together in freezing temperatures. If exposed to a Human based environment, this body structure simply boils, melts and evaporates, which was why they required their encounter suits. While they did possess a skeletal structure, there were no bodily organs except for eyes, ears, tongues, brain, a pair of lungs along with a layer of purple-blue layered skin which provided a level of tactile sense. Their nostrils provide them the capacity to filter oxygen but do not give them a sense of smell.

The internal structure of the Breen body consisted of layers of permeable chambers that were filled with gelatin which maintained a semi-solid state when in an extremely cold environment while it broke down when exposed temperatures of 70 degrees Fahrenheit or above. The gelatin compound moves from one chamber to another where it transfers chemicals that are required for different functions such as digestion, reproduction or regeneration. Such an organism goes through similar patterns as Humans but lack the capacity to bleed. Any wounds simply seal up with a hard layer of gelatin which leaves a calcified scar unless it's treated with Breen medical techniques. (ST reference: Aliens, DS9 episode: "The Changing Face of Evil")

The concept of hot temperature causing the Breen body to evaporate may be an explanation as to why Skrain Dukat and Kira Nerys never reported on the Breen appearance after they stole the costume of two Breen guards on Dozaria.

The brain structure was also notably different from Humans as it was separated into four lobes. This provides the race the capacity to protect themselves from the telepathic abilities of species like the Betazoids. (DS9 episode: "In Purgatory's Shadow", TNG episode: "The Loss")


Little was known about the race as they tended to keep to themselves. What was known was that they were both secretive as well as aggressive though it must be stated that they did not exalt violence for its own sake and that it was aggression that served a purpose. Furthermore, they were known to intentionally keep their motives and feelings hidden from other races which, when combined with the fact that they cannot be sensed by Betazoids, further adds to the mystery of the Breen. Common speculation among other races was that the Breen were more open to their own kind but this was never confirmed. Their spoken language (at least to non-Breen) sounds like uncomprehensive static. Even though this electric chatter is understood by Vorta and Founders.

Members of this race were not excessively individualistic and were in fact commonly encountered in groups. Furthermore, the level of secrecy that they have maintained about their society and world hints at a high level of clan cohesion or possibly even a government structure. This form of society has yet to produce any form of rebel that was willing to break the silence about their customs, culture or homeworld. When alone, Breen tend to act unpredictable and quirky with displays of neurosis due to the fact that they are working apart from their group. While this hinted that Breen are incapable of working alone, xenologists have stated that this behavior may in fact be faked in order to produce the illusion of such traits in order to fool other races. (ST reference: Aliens)

The Breen were disliked by the Romulans, who had a saying: "never turn your back on a Breen". (DS9 episode: "By Inferno's Light") The nature of why the Romulans distrust the Breen so much remains unknown. They, however, earnt this reputation through their opportunistic tendencies of preying on the conflicts of other species while at the same time, rarely interacting directly. This was because they wished to profit on such activities which included slavery. (ST reference: Aliens, DS9 episode: "Indiscretion")

What was known about the Breen race was that they tended to act out of their own self-interest with little weight placed on the hardships by those that stand in their way. They appeared callous to the suffering of others and in fact do not heed calls for aid unless there was something to gain from such an endeavour; be it monetary, technology or simply territory. (ST reference: Aliens) While the Breen were quite capable of acts of deceit, Elias Vaughn thought it unlikely they would attempt to build up a military presence in hiding-as it did not fit with their cultural psychology. (DS9 novel: Avatar) It's known that they are not above using others in their schemes where the relationship was that of a pawn rather then a partner. Regional conflicts among other empires was noted to result from Breen provocation with the race being blamed for activities that they themselves have not committed even. (ST reference: Aliens) Their society also was believed to contain some aspects of a manifest destiny. (TNG novel: The Buried Age)

Though elements of their society remain a mystery, it was known they possessed two genders and that it was typical for them to bear children at a young age. The reason for this puzzled xenologists who conclude that the the Breen possibly suffer from a high mortality rate and that they encourage this behavior in order to ensure their population remains at a steady level. Another theory was that they had a shorter lifespan compared to Humans and simply reached maturity quicker. However, the truth of the matter continues to be unknown. (DS9 episode: "For the Uniform", VOY "Elogium (episode)")

The Breen were politically nonaligned and did not take part in official treaties or alliances though their representatives on occasion visit certain diplomatic gatherings. However, the selection process of which gathering they do attend was a mystery to other races. What was determined, however, was that they seek to gather information in such meetings, not to participate in them. The fact that they do not appear to be an expansionistic race has meant that other races typically leave the Breen alone.

The government itself appeared to resemble a form of primitive tribalism except that all Breen were a member of the same tribe. Members were noted to form into groups where different individuals assume different roles on a voluntary basis rather then an autocratic dictate. Their leaders rule as long as their groups allow them to do so with their starship tactics following a similar role with each vessel seeming to possess a high degree of independant autonomy. These ships appear to only work with others through mutual consensus or agreed-upon tactics. (ST reference: Aliens)


Breen refrigeration suits, at least those of military issue, are manufactured in different designs signifying rank. The style worn by command officials has golden lining on the shoulders and arms, as well as distinctive gold stripes that run down the center of the top of the helmet and down the top of the "snout" section. Gold is a favoured colour among the Breen, symbolizing elevated social status and prosperity. This is due to the scarcity of the metal Gold on the Breen homeworld (Humans also attach value to the colour for this reason).


22nd century

During the 22nd century, the Breen were largely confined to their own home system with few forays being outside their region of space due to refrigeration technology being too primitive to allow them to survive on other worlds. (ST reference: Aliens)

In the time of the Second Klingon Empire, Chancellor Mow'ga sent a fleet into Breen space to conquer the race but they were never heard from again. (DS9 episode: "'Til Death Do Us Part")

The Vulcan race were aware of the existence of the Breen before the year 2155 though their Vulcan Security Directorate knew very little about the species except that they made use of disruptor technology and kept to themselves. (ENT novel: Kobayashi Maru)

The Breen also had early contact with the Ferengi, beginning the age of Ferengi trade on the galactic scale by selling the race warp drive technology. (ST short story: "A Dry Day on Ferenginar"; DS9 reference: Legends of the Ferengi)

There are two conflicting accounts of this transaction; The "A Dry Day on Ferenginar" details how one of the first Ferengi to leave their homeworld, Greko, purchased an old out-of-date warp drive from the Breen, later taking back to Ferenginar. Legends of the Ferengi explains how a Breen known as "The Masked Breen" (as the Ferengi did not yet know that all Breen wear suits that completely covered their elongated faces) visited Ferenginar and sold the technology to the Ferengi government, in exchange for both the planet's poles and several frozen moons and comets. The Masked Breen's sales pitch became the only Rule of Acquisition to be coined by a non-Ferengi: "Rule #95: Expand or die".

23rd century

By the 23rd century, the race had improved their environmental suits to the point that they had the capacity to travel far greater distances. It was during this period that the race offered their services to other governments that required covert agents or mercenaries. Despite this expansion into space, the Breen generally kept to themselves, with the Federation not being aware of the existence of the species. (ST reference: Aliens)

The Romulans made first contact with the Breen in 2268, and were soon using them in covert operations and illegal work. The Federation made first contact with the Breen in 2275, with a minor clash erupting between the two by 2283. (ST roleplay module: All Our Yesterdays: The Time Travel Sourcebook)

24th century

In the 24th century, they had fully developed the means to join the galactic community but remained inscrutable with their goals being enigmatic to other empires. They tended to enter specialized markets to leverage skills in intelligence work, mining and technology that dealt with survival on colder environments. The Federation had become fully aware of this empire's existence and recognizes that they had developed several technologies like the disruptor from trade with the Romulans or other races. (TNG movie & novelization: Generations) However, it was concluded that the mysterious insular species were neither a threat or potential ally. (ST reference: Aliens) In 2328, the Federation constructed Deep Space 3 to monitor the Breen and those species that resided in their space. (LUG reference: Star Trek Deep Space Nine: Core Game Book (LUG RPG)) Relations between the Federation and the Breen were described as tenuous at best by the year 2360. (TNG novel: The Buried Age)

During Benjamin Sisko's time on the USS Saratoga, the starship encountered a hostile Breen ship near Guldammur IV. In a plan devised by Sisko and Zar, a narrow-gauge phaser spread was fired from the weapons of the Saratoga, making several small gaps in the Breen's shields. This allowed the Saratoga crew to beam unwanted items into the Breen's weapon banks, clogging them and leaving the Breen unable to fire. (DS9 novel: Saratoga)

In 2366, the Breen attacked the Ravinok and forced it to crash on Dozaria. The Bajoran and Cardassian survivors were forced to mine dilithium by the Breen. (DS9 episode: "Indiscretion")

In 2372, Breen privateers were operating near Bajor. (DS9 episode: "To the Death")

Some years prior to 2377, Captain Marcus Refelian distinguished himself in defending a group of Federation colonies from attacks by Breen raiders. (TNG video game: Away team)

The Dominion War

The Dominion made attempts to forge an alliance with the Breen as early as 2374. It was the possibility of finding themselves on the same side as the "accursed" Breen that made the Romulan Star Empire reticent to ally itself with the Dominion. (DS9 episode: "The Magnificent Ferengi", ST short story: "Blood Sacrifice") At he same time, the Federation was engaged in talks, and by 2375, Starfleet Admiral Marcus Holt reportedly made some progress in improving Federation/Breen relations. (LUG reference: Star Trek Deep Space Nine: Core Game Book (LUG RPG))

San Fransico following the Breen attack

However, in the same year, the Confederacy allied themselves with the Dominion in the Dominion War and shortly after launched an attack on San Francisco on Earth. (DS9 episodes: "Strange Bedfellows", "The Changing Face of Evil")This was a surprise to many military strategists, as the Breen were considered strategically unimportant, even though their fleet strengths had never been charted. (ST reference: Aliens)

Thot Pran led the Breen forces at the Battle of Cardassia. However, after the Cardassians broke ranks with the Jem'Hadar and began fighting alongside Federation Alliance forces, the Breen ships fled from the battle and retreated back into their space. (DS9 episode: "What You Leave Behind")


The Breen continued to be a source of some concern following the war. In April 2376 the USS Enterprise-E was sent to investigate the Badlands for a Klingon reported Breen presence. Nothing was found and Elias Vaughn thought it unlikely the Breen would build up a military presence in hiding, though it was consistent with other, need-to-know only, reports he had received not long before. (DS9 novel: Avatar)

Cole of Section 31 told Julian Bashir several weeks later that he thought it likely the Breen would be watching the Federation's borders and would make raids when they found a weakness. However, Cole also told Bashir he thought the Breen could be useful in fighting off a future Borg attack. (DS9 novel: Abyss)

An unusual amount of Breen activity was detected along the Federation-Cardassian border near Starbase Deep Space 10 in mid 2377. They were briefly considered as possible culprits in a series of malfunctions that had plagued the station, but eventually ruled out. (CoE eBook: Troubleshooting)

In 2379, a contingent of Starfleet Special Operations personnel was able to capture a Breen vessel in the Ravaner system, although their actions were officially denied by the Federation Security Council. Ambassador Worf was able to obtain these schematics to trade to Imperial Intelligence agent Lorgh in exchange for blackmail information against Klingon Councillor Kopek. (TNG novel: A Time to Kill)

Typhon Pact

In 2381, during the Borg Invasion, the Ferengi Alliance, acting on behalf of the Federation, hired a large number of Breen warships to assist in the defense of the Azure Nebula, precluding the possibility that the Tholian Assembly would hire them to attack the weakened Federation. Unfortunately, every Breen ship was destroyed by a Borg armada of over 7,000 cubes (Star Trek: Destiny novel: Mere Mortals)

After learning of the behind-the-scenes dealmaking, the Confederacy joined with the Tholians, along with four other local powers, to form the Typhon Pact. (ST novel: A Singular Destiny)

A Breen in 2375.
Planet: Breen
Goverment: Breen Confederacy
Location: Alpha Quadrant
"Never turn your back on a Breen".
-Romulan axiom (DS9: "By Inferno's Light")

The Breen are an reclusive species, native to the Alpha Quadrant.



Chancellor Mow'ga of the Klingon Empire, was one of the first modern powers to learn of the destructive force of the Breen. An entire fleet was lost when he ordered an invasion of the Breen homeworld. (DS9: "'Til Death Do Us Part")

First contact between the Federation and the Breen was in 2275. (Last Unicorn Games’ All Our Yesterdays: The Time Travel Sourcebook)

During the 24th century, Breen often pirated vessels and colonies of other races. (TNG: "Hero Worship"; DS9: "Indiscretion", "To the Death") The Breen were also known to support privateers, with the USS Minnesota battling Breen privateers in 2369 led to the ship's destruction. (Star Trek: Minnesota: "Scream") The wanted Ubessian criminal Yaghim Thau also joined forces with Breen privateers against the USS Prospect-A in 2371, with the privateers and Thau failing and being taken into custody. (Star Trek: The Prospect Chronicles: "Ramifications")

The Breen have also been known to sell cold-storage units to the Maquis. (DS9: "Penumbra")

In 2375, the Breen made the surprising move to join the Dominion. The Founder promised the Breen control of the Romulan Star Empire and Earth in the post-war. (DS9: "Strange Bedfellows")

It is unknown if the Breen were manipulated into joining the war by a Changeling, or not.
Remains of San Francisco after the Breen Attack - During the Dominion War
In their opening attack against the Federation, the Breen attacked Starfleet Headquarters on Earth. (DS9: "The Changing Face of Evil")

Then, the Breen greatly aided the Dominion in re-taking the Chin'toka system; due, in large part, to a previously unknown energy dampening weapon. (DS9: "When It Rains...")

The Breen proved to be as loyal to the Dominion as the Jem'Hadar. They were more than willing to fight, even after the Federation discovered a defense against their unique power draining weapon. The war turned against them, however, and they surrendered along with all other Dominion forces at Deep Space Nine. (DS9: "What You Leave Behind")

There has been a massive reordering of the Confederacy following the Dominion War, the Thots, or war chiefs, that led the Confederacy into war have been executed, and their bloodlines negated. (Dark Territory "Corruption of Blood")

In 2382, the Breen signed a treaty with the So'ja Coalition, which brought them into the Coalition War, against the Federation. (Star Trek: Pioneer (STP): "Everything Changes")


A Breen government is known as the Breen Confederacy. (DS9: "Til Death Do Us Part")

The Breen are a sexually segregated species. Males are join the Confederacy, while females are part of another government, called the Gynarchy. (Dark Territory "Corruption of Blood")


The Breen have no blood as many species define it and their brains are four-lobed, preventing many forms of telepathy. (DS9: "In Purgatory's Shadow"; TNG: "The Loss")


Like many things about the Breen, their home planet is a mystery. Many claim it is a "frozen wasteland," hence the need for the refrigeration suits they wear. However, there are disputing claims that the planet is temperate. (DS9: "The Changing Face of Evil")


The Breen utilize slave labor. Often, the slaves are taken in raids. (DS9: "Indiscretion")

They do not underestimate their prisoners. They use a neural truncheon and then still have several guards. (DS9: "Strange Bedfellows", "'Til Death Do Us Part")

The Breen also utilize cortical implants to get information from others, even though they cause brain damage. (DS9: "'Til Death Do Us Part")

The species reproduces at a relatively early age. They also have some form of nursery rhymes. (DS9: "For the Uniform"; VOY: "Elogium")

To ensure the survival of their species, both sexes supply reproductive fluids, which are joined at neutral sites, and then the eggs are incubated and the hatchlings are brought to term and then sent to their respective worlds. (Dark Territory "Corruption of Blood")


Without a universal translator, the Breen language sounds like a chaotic mix of electronic noises.

It is unknown if this effect is their "true" language or simply created by their helmets.


A Breen starship in 2375

The Breen seem to be at least as advanced as the Federation, if not more so.

The species use organic technology in their ships. Some vessels have been known to be equipped with cloaking devices. (VOY: "Scorpion"; TNG: "Hero Worship")

They also produced a powerful hand-held energy cannon known as the CRM-114. (DS9: "Business as Usual")
