First Officer Chrupp is a Pkunk crew member aboard one of his race's Fury vessels. When The Captain encountered their ship in space, having previously attacked another of their kind, Chrupp was understandably somewhat nervous. When The Captain said that he no longer meant the Pkunk any harm, this prompted the captain of the Fury to turn to Chrupp and mention that due to the colours of The Captain's aura, he must be on the side of truth and light. Chrupp remained skeptical, and primed the ship's shields and guns, "just in case". The Fury's captain was somewhat disappointed by this.
