Mart McChesney as Armus
Synopsis: A shuttle containing Troi and a pilot is returning from a conference when it crash-lands on Vagra II. When the Enterprise locates the shuttle interference prevents them from using their sensors or transporters to beam up the two occupants. The away team find an alien named Armus which appears like an oil slick but is able to assume humanoid shape at will. Armus blocks their path and prevents them from rescuing their comrades. During the encounter, Armus taunts the crew as they attempt to reach the shuttle.
