Locke (The Seeds of Death)

Locke 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 Phipps repaired the video link to Earth to warn them of the invasion, but was found out and killed. (DW: The Seeds of Death)
