Menen was an elderly male who resided on Deneva in the 2260s. When neural parasites infected Deneva in 2267, Menen and a young girl named Aurelan barrackaded themselves inside the colonies communications center. They were eventually rescued by Captain James T. Kirk and a landing party from the USS Enterprise, and transported up to the ship's sickbay for immediate medical attention. One of the many people taken over by the parasites, included Menen's son, Noban. (TOS novelization: Operation -- Annihilate!)
