Species 116 - Delta Quadrant

Species 116 displayed an aptitude for "seeing patterns where others see only confusion" allowing them to notice patterns of all forms and precisely extrapolate that pattern further which enabled them to learn the correct grammar and syntax of entire languages after only hearing a few phrases. Other forms of patterns such as encryption algorithms were also very easy for this race to decipher.

Species 116 utilized a propulsion system named a Quantum Slipstream which enabled them to "avoid the storm on the horizon" and outrun the Borg for centuries before the Borg became more and more capable of pursuing the vessels due to the assimilation of Transwarp technology, expanding and assimilating the surrounding systems until finally the species were cornered in their own space. (VOY - "Hope and Fear"). Then the Species 8472 war broke out between the Collective, Species 116 saw this as their last hope that the Borg would be destroyed before the U.S.S. Voyager aided the Borg against the invaders for their own personal gain. (VOY - "Scorpion"). Due to their assistance, the Borg defeated species 8472 and assimilated all but 10,000 members of species 116 which held Voyager accountable for the destruction of their race as the Collective continued to expand and finally surrounded their system with hundreds of cubes (VOY - "Hope and Fear").

Species 125 - Delta Quadrant

This is the species from which the Borg Queen herself originates, the species possessed an over-sized cranial region exhibiting telepathy and extraordinary mental processing capacity. When they are sufficiently challenged enough to be required to give their tasks a degree of attention, they will twitch their heads and when extremely challenged they will focus by closing their eyes.

Species 149

Species 149 was regarded as a medically technologically advanced species. The Borg assimilated knowledge involving nanoprobes for the reanimation of a lifeform as long as 73 hours following death. Provided the neural pathways are intact, 70 micrograms of nanoprobes which are pre-modified to the specific subject's physiology are sufficient to reverse cellular necrosis while the cerebral cortex is stimulated with a neural electric isopulse at 1 second intervals, Nanoprobes can compensate for any cellular degradation after the technique is completed. However, the subject requires regular doses of additional modified nanoprobes until the victim's cells are capable of functioning on their own (VOY - "Mortal Coil").

Species 180 - Ferengi - Alpha Quadrant

Species 180 name themselves as Ferengi. Ferengi were encountered early by the Collective. However, why a vessel belonging to a race originating in the Alpha Quadrant was found in the Delta Quadrant remains a mystery.

Species 218 - Talaxian - Delta Quadrant

Species 218 name themselves as Talaxians. The Collective assimilated a small freighter belonging to Species 218 in the Dalmine Sector, assimilating the crew of 39. Their dense musculature made them excellent tactical drones. (VOY - "The Raven")

Species 259

Species 259 are an advanced omnicordial lifeform which inhabited Galactic Cluster 3. The species numbered some 22 billion when they were assimilated and had developed an advanced pattern-duplication design that was later incorporated into Borg autonomous regeneration sequencer technology.

Species 262

Deemed to be a relatively primitive species by Borg standards, following their assimilation in the 22nd century. Their mythology referred to a substance which could "burn the sky". The Borg were intrigued and later discovered it to be a reference to the Particle 010 (Omega Molecule)

Species 263

Deemed to be a relatively primitive species by Borg standards, Species 263 was the second in a series of thirteen species assimilated in the pursuit of attaining any and all information relative to Particle 010. In the mythology of the species, they believed the molecule to be a drop of blood from their creator.

Species 312

Species 312 was a race assimilated by the Borg before 2374 possessing advanced tetryon-based energy barrier technology. Sometime before their assimilation, the race constructed an energy barrier around the planet Ledos in the Delta Quadrant. This was several hundred years before 2377, to protect the primitive race on the surface from the interference of other warp capable species.

Species 329 - Kazon - Delta Quadrant

Species 329 name themselves as Kazon, a relatively primitive, yet warp-capable species with a limited understanding of the technology in their possession which they gained control of after conquering their former oppressors. Their technology and biological lifeform was deemed unworthy of assimilation.

Species 407

A species named the Lennli.

Species 521 - Delta Quadrant

A humanoid species native to the Delta Quadrant.

Species 571 - Delta Quadrant

A humanoid race based in the Delta Quadrant which according to their own established mythology worship the god Brothera. The species was assimilated sometime before 2369 after-which three drones escaped from a Borg Sphere which crashed landed on Planet 1865-Alpha severing the three drones from the Collective mind.

Species 689 - Norcadian - Delta Quadrant

Species 689 name themselves Norcadian, an advanced humanoid species native to the Delta Quadrant and the planet Norcadia Prime. This species hosts a violent sport named Tsunkatse.


Species 2000 - Cardassian - Alpha Quadrant

Species 2000 name themselves Cardassian, a warp-capable species native to the Alpha Quadrant and the planet Cardassia Prime. Known to be highly xenophobic and ruthless.

Species 2461 - Brunali - Delta Quadrant

Brunali were once a standard space faring species. However, following the Borg constructing a transwarp conduit directly to their homeworld, they became subject to frequent attacks by vessels passing by. Following this, the species returned to a low state of technology with all of their remaining technology hidden beneath the surface. No longer possessing advanced space faring weaponry, the Brunali turned to their skills in genetic technology. Engineering a number of their children with an anti-Borg pathogen encoded in their DNA, they used their children as weapons, sending them towards their nearby transwarp conduit for the purpose of infecting Borg vessels.

Distinctive Technology: The Brunali Pathogen - upon assimilation, the pathogen kills every drone aboard the vessel, the pathogen is, however, unable to cross the defenses of the Vinculum which prevents it from infecting the entire Collective. Vessels infected with pathogens of this nature are disconnected from the Hive Mind.

Species 3105 - Rhawn

Species 3259 - Vulcan - Alpha Quadrant

The Vulcan species are primarily pacifists by nature. Although space-faring, they maintain a strong connection to their established religion. The species is most notable for their extremely developed mental abilities and touch-telepathy.

Species 3783 - Romulan - Alpha Quadrant

Species 4228 - Hazari - Delta Quadrant

The Hazari are a race of bounty hunters in the Delta Quadrant. Their physiology made excellent tactical drones.

Species 4774 - Skedan

Species 5008 - Klingon - Alpha Quadrant

Species 5174 - Delta Quadrant

A race native to the Delta Quadrant, the Borg once encountered a small vessel belonging to the species. The crew onboard had been eviscerated, the Borg considered the matter irrelevant and did not investigate further. It was later revealed the Hirogen were responsible.

Species 5618 - Human - Alpha Quadrant

An unremarkable race in terms of biological distinctiveness, possessing below-average cranial capacity, minimal redundant systems and limited regenerative abilities. Humans are, however, technologically advanced. They are also the founding race of the United Federation of Planets, an alliance of 150 races spanning 8,000 lightyears. Humans are considered by the Borg to be a highly resistant species. Several direct attempts to assimilate the species have failed (Star Trek: First Contact, TNG - "Best of Both Worlds") The Borg are currently developing a new method of assimilation via a nanoprobe virus.

Species 5973

Species 5973 is the designation for a multispectral particle lifeform native to Galactic Cluster 8.

Species 6291 - Yridian - Alpha & Beta Quadrants

Yridians are renowned information merchants native to the Alpha and Beta Quadrants.

Species 6339 - Grid 124, Octant 22-Theta

Species 6339 are a humanoid, warp-capable species originating in Grid 124, Octant 22-theta. The Borg encountered the species in 2371. By 2375, the Collective had assimilated over eleven billion individuals. Due to their partial extinctions as a result of the Borg, Species 6339 maintained extremely well-armed vessels, possessing over 22 phaser cannons on their aft sections alone. In 2375, the Borg detected a shuttle craft belonging to Species 6339 possessing 13 lifeforms aboard. A cube was dispatched to intercept and assimilate the vessel. However, Species 6339 had developed and infected the lifeforms with a synthetic pathogen designed to attack the programming of a Borg vessel's vinculum causing it to malfunction. Due to the malfunctioning vinculums, the drones on-board developed a form of multiple-personality disorder and partial insanity resulting in the destruction of the Borg cube. Each Borg vessel which attempted to retrieve the vinculum would also be affected, which Species 6339 hoped would result in the eventual destruction of hundreds of vessels (VOY "Infinite Regress").

Species 6961 - Katarian

Species 8472 - Fluidic Space

Species 8472 is regarded by the Borg as the ultimate form of biological evolution, they are a space-faring, telepathic, extremely xenophobic, non-humanoid species originating from an extradimensional realm named Fluidic Space. All of their technology is organic and is immune to all forms of technology such as: Borg nanoprobes, sensors, tractor beams, and transporter beams. They possess a triple-helix DNA coding making them the most densely-coded lifeform ever encountered.

Species 10026

Species 10026 is the Borg designation for a warp-capable species whose homeworld was assimilated by the Borg in 2375 resulting in the assimilation of 392,000 lifeforms and 39 vessels. The Queen dispatched two Borg cubes and accompanied them within her own personal diamond. Initially, species 10026 dispatched vessels to intercept and combat the Borg using their modulating phaser pulse which allowed them to successfully damage Borg vessels. The Borg Queen was able to adapt easily by triaxilating the Borg vessels' shield geometry to absorb the phaser pulses. However, she allowed the vessels to attack her Diamond until her shields almost failed in an effort to provoke 7 of 9's assistance in adapting, and ultimately assimilating, the species.
