A Dalek Saucer Commander commanded the Dalek flying saucer X-K Beta-19.

It ordered the Daleks to drill to the planet Galacton's core and energise its Radio-Activan to provide a fuel source for the Dalek Seventh Fleet. When two Daleks failed to return from this, it ordered the dispatch of Dalek Attack Squad Delta to find them. When a group of red-eyed creatures attacked the saucer upon landing, the Commander ordered an evacuation. Later, it watched as the planet was ripped apart due to the efforts of the Dalek Attack Squad Leader energising the core, making the mission a success. (PROSE: Mission to Galacton)
