Unnamed Rigelians
The following is a list of unnamed Rigelians.

Ambassadors  
These two ambassadors participated in the meeting discussing the Coalition of Planets in 2155. They also witnessed John Frederick Paxton's actions against the aliens. ()

Kidnappers 
These three kidnappers emerged from the shadows of the late night streets of San Francisco in 2155. They surprised Doctor Phlox and Ensign Hoshi Sato and wanted to take Phlox with them. Sato attacked one of the kidnappers and threw him over her shoulder while Phlox attacked the other one. The third came out of the shadows and knocked down Sato and shot at Phlox. Sato was only able to see how the three took Phlox with them. ()

Test subjects 
These Rigelians were successful test subjects for a stimulant that sped up the reproduction and replacement of blood. In 2268, Spock directed Doctor Leonard McCoy's attention to the drug in question, suggesting that it be used on him so he could donate blood to his father Sarek in order to facilitate the latter Vulcan's cyrogenic open-heart procedure. He mentioned these test subjects as proof that the drug was safe, but McCoy was apprehensive, as he misunderstood Spock to be suggesting that Sarek take the drug. Despite the Rigelians' physiology being similar to Vulcans, the doctor felt that wasn't enough to prove the likelihood of similar success with Spock. ()
