The pre-warp humanoid inhabitants of the desert world Kolarus III, near the Romulan Neutral Zone, who attacked Picard's landing party as it collected the scattered pieces of the android B-4.
The Kolarans appear in Star Trek Nemesis. Their planet lies close to the Neutral Zone and is home to a pre-warp civilisation at an early stage of industrial development, living apart from the Federation.
In 2379 the Enterprise-E detects positronic signatures on Kolarus III. Picard, Data and Worf go down in the shuttle Argo and use its wheeled ground vehicle to gather the dismantled parts of an android resembling Data, later identified as the prototype B-4.
Kolarans in armed desert vehicles appear and open fire without warning. Picard drives while Worf mans the rear gun, and the chase ends when Data remotely flies the shuttle to the edge of a cliff and Picard drives the vehicle straight into its open hatch. The android had been planted there by Shinzon as bait to draw the Enterprise towards Romulus.
