T'raltixx was a sinister, light-loving alien who boarded Moya under the pretense of adjusting her electromagnetics to make her untraceable. He claimed that the Leviathan could be fitted with a device that would complete the modification at his home planet and offered to guide her through a region of space known as the Five Pulsars. T'raltixx claimed that the light from the pulsars was known to affect "lesser species" and used this as an excuse when the crew of Moya began exhibiting strange behavior. In truth, however, it was T'raltixx himself who affected the crew, turning them against each other and taking their attention off of him.
