Phipps (The Seeds of Death)

Phipps was a maintenance crewmember of T-Mat Moonbase. When the base was taken over by Ice Warriors, they ordered him to assist Fewsham in repairing the damage Osgood had done to T-Mat. Instead he and Locke repaired the video link to Earth to warn them of the invasion. Locke was killed, but Phipps escaped, and later helped the Second Doctor fight against the Martians. He was killed while helping Zoe increase the base's temperature to disable the invaders. (DW: The Seeds of Death)
