For for the reptilian species with a similar name, please see Rigellian.

The Rigelians were a warp-capable humanoid species who inhabited the planet Rigel V. (TOS: "Journey to Babel")

Physiology Edit

Rigelians were believed to have four or five genders, according to information obtained by Doctor Phlox. (ENT: "Cogenitor")

They are known to have shared a similar internal physiology with Vulcans and Romulans. These similarities, notably to Vulcans, included similar blood chemistries. Rigelians also shared a similar neurology to Vulcans and Romulans, as they too were susceptible to the neurological disease known as Tuvan Syndrome. (TOS: "Journey to Babel"; DS9: "Inter Arma Enim Silent Leges")

One of the ancestors of a Human corpse from the 31st century was discovered by Dr. Phlox to be a Rigelian, based on the individual's nucleotide sequence in his DNA. (ENT: "Future Tense")

History and politics Edit

Relationships with other species Edit

During the 22nd century, Rigelians maintained relationships with several Alpha and Beta Quadrant species. By the 2150s, it was not uncommon to find a Rigelian visiting Earth.

In 2154, an Andorian and two Rigelians were attacked on Earth in a wake of xenophobia after the Xindi incident. (ENT: "Home")

Later that year, three Rigelians visiting Earth, who were working for the Klingons, attacked and kidnapped Dr. Phlox from the streets of San Francisco. They later transferred him via a Rigelian freighter to a Klingon ship. The Rigelian kidnappers and their ship were later destroyed. (ENT: "Affliction")

In 2154, a Rigellian scoutship fell victim to an attack by a Romulan drone ship which disguised itself as Earth starship Enterprise in order to destabilize the sector. Recognizing the vessel, the Trade Commission contacted Starfleet to demand compensation for the loss of their vessel and the arrest of Enterprise's commanding officer, Captain Jonathan Archer. (ENT: "United")

In early 2155, the Rigelians participated in talks discussing their wish to join as a possible member in the Coalition of Planets along with Humans, Tellarites, Andorians, Coridans, and Vulcans. (ENT: "Demons", "Terra Prime") During the negotiations, six of the Earth universal translators experienced a "glitch" and started confusing the Rigellian language with Andorian. (ENT: "Terra Prime")

Trade and commerce Edit

Rigelian commerce was regulated by the Rigellian Trade Commission during the 22nd century. (ENT: "United")

The Rigelians independently operated their own freighters during the 24th century. In 2369, one of these freighters docked at Deep Space 9 prior to its mission to the Gamma Quadrant. (DS9: "Vortex")

Medical achievements Edit

Rigelians were responsible for developing a unique gene therapy technique that was capable of curing medical conditions such as Taggart's Syndrome. (ENT: "Demons", "Terra Prime")

During the mid-2260s, an experimental chemical stimulant designed to speed up reproduction and replacement of blood in the bodies of certain species was developed and successfully tested on Rigelian test subjects on the planet Rigel V. Although the side-effects included tremendous strain on the spleen and the liver, it was later discovered by Doctor Leonard McCoy to be a viable treatment for producing Vulcan T-negative blood. (TOS: "Journey to Babel")

Background information Edit

The species name was spelled both as "Rigelian" and "Rigellian" in scripts, but in those few episodes in which they appear, the same make-up was used regardless of spelling. The name Rigellian was also given by behind the scene sources to a turtle-like species developed for a crowd scene in Star Trek: The Motion Picture.

The homeworld of the Rigelians has not been firmly established, but it is known from TOS: "Journey to Babel" that Rigelians were at least present on Rigel V in the mid-23rd century.

A note in the final draft script of ENT: "Affliction", the only episode in which the species appears, described Rigelians as "an often mentioned, but never-before-identified species."

Apocrypha Edit

The Rigelians are a playable species for the Federation in the game Star Trek Online.

The novel Tower of Babel establishes that there were three species of Rigelians. These included:

All Rigelian species were politically united and the Rigel system was considered to be a crowded and bustling population center in the novels, with its three native species and numerous colonists from other species.
