The Caatati civilization was almost entirely assimilated by the Borg, except for 27 ships. These escaped carrying a small number of survivors but were forced to wander throughout space, begging from other species.

Their technology was thorium-based, but they had lost the ability to replicate the element and so they gradually were running out of power and time.

In 2374 a Caatati ship encountered the USS Voyager and were given stocks of food, all they could spare. A little later, they found Voyager’s warp core after it had been dumped and claimed it. They then traded it for their lost thorium replication technology that Seven of Nine remembered from her time as a borg.

Telepathic humanoid race which, until recently, were unaware of spoken language. The Cairn have no concept of spoken language and have almost no vocal ability.

Known throughout the Alpha Quadrant for their ruthlessness, the Cardassians became one of the greatest enemies of the United Federation of Planets and Klingon Empire when they joined the Dominion in 2373.

They treat their prisoners with little tolerance or sympathy, and had no qualms with using torture to extract information. Some Cardassians were even known to enjoy torturing their prisoners and to do it whether there was information to be extracted or not.

They occupied Bajor for over 60 years and built Terek Nor, now known as Deep Space Nine, initially as a mining station.

The Obsidian Order is a Cardassian intelligence organization in the Star Trek universe. Security Chief Odo of Deep Space Nine remarked that it was one of the most brutally efficient organizations in the galaxy, being even more ruthless than the Romulan Tal Shiar. The Order kept very close tabs on all Cardassian citizens to ensure loyalty, and was greatly feared.

They joined the Dominion war on the side of the Dominion. This alliance was beneficial at first but ended in the death of almost 1 billion Cardassians when Cardassia Prime was struck by Jem’Hadar raids and orbital bombardment from the Dominion and Breen forces in orbit of the planet.

Changeling

Life Span: Believed to be biologically immortal.
Warp capable: Yes
Classification: Shapeshifter
Environmental requirements: Various
Telepathic abilities: None
Federation Status: Peace treaty
Affiliation: Dominion
First Encountered: Odo was the first member of this Gamma Quadrant race encountered by the Federation. (DS9: Emissary)
Distinctive Features: Changelings could take virtually any corporeal form, ranging from humanoid aliens to fog to reflective surfaces. In its natural state, a Changeling’s body was a formless gelatinous mass, to which it had to revert every eighteen hours.
Known members: Odo, Female Changeling, Laas

 

changeling2Also called the Founders, the Changelings were liquid-based, shapeshifting lifeforms native to the Gamma Quadrant of the Milky Way Galaxy. They wished to instill order throughout the galaxy.

The Founders of the Dominion were Changelings, and made up the majority of the Dominion’s leadership. The Founders were greatly feared.

Changelings preferred to think of themselves as a drop (the individual) in the larger ocean (what they call the Great Link). A Changeling, therefore, typically had little sense of individual identity. Being a liquid-based lifeform, in order to link with other Changelings they simply reverted to this state and the liquid blends together, creating a link between them.

Crystalline Entity

crystalline_entityHomeworld: Interstellar space
Warp capable: Yes, natural
Classification: Cosmozoan
Environmental requirements: Interstellar space
Federation Status: At war
First Encountered: TNG: Datalore
Distinctive Features: crystalline structure that resembled a large snowflake

The Great Crystalline Entity was a powerful, space borne creature characterized by a crystalline structure that resembled a large snowflake. It had warp speed travel capability, formidable size, and the ability to consume all life on a planet or starship.

The Entity functioned as a giant electromagnetic collector and needed constant power, converting organic matter into energy. Once the Entity ravaged a planet, the planet’s natural resources were completely stripped. No further life would be able to grow for many years. Everything, including vegetation and bacteria, was completely converted.

In 2336, the Entity was lured to Omicron Theta by Lore, where it fed on the planet, destroying the colony and killing almost all of its inhabitants.

In 2364, after Lore was reactivated by the crew of the USS Enterprise-D, he again summoned the Entity so that it could feed on the ship’s crew. The Entity departed after Lore was beamed out into space.

Cytherian

cytherianHomeworld: A planet near the center of the galaxy.
Federation Status: Allied
First Encountered: TNG: The Nth Degree
The Cytherians were explorers and made first contact with other races by bringing the other races to them rather than traveling the galaxy in search of intelligent life.

In 2367, the USS Enterprise-D encountered an alien probe while attempting to repair the Argus Array. The probe was able to reprogram Lieutenant Reginald Barclay’s brain, briefly enhancing him so he would bring the ship to the Cytherian homeworld via a subspace distortion.
