Moira Brody

 was a Dalek slave. Peri Brown met her on board as Dalek ship. She was interested in how Peri Brown knew about the Daleks and what the Sixth Doctor knew about it. She tried to sell Peri out, but this as a ruse to help them escape. She later drove a truck through some Daleks. She was part of the resistance and recommended going to the Orkney Islands. She was important in the history books, as part of the rebuilding of the Earth. She fell of a boat, and was dragged away by Slythers, but managed to escape it. She was working for the Daleks all along. She was a Roboman Elite, but managed to break through the conditioning. (AUDIO: Masters of Earth)
