Parmen was the leader of the Platonians, a humanoid species who possessed psychokinetic powers and copied the ancient Greeks. Parmen was the product of a mass eugenics program on the planet Sahndara. He was bred for contemplation, self-reliance, and longevity. The number of individuals generated by the program was pared down to thirty-eight. Before the planet's star went nova, this group resettled on Earth where they were exposed to the Greek civilization. When this civilization died, they moved on to Platonius where they founded their republic. Parmen was played by Liam Sullivan.
