Medea (The Paradox Planet)

 was the controller of the Time Tanks and negotiated their take off from the future. (AUDIO: The Paradox Planet) She was one of K9 Mark II's Machina fanatics and facilitated the Fourth Doctor's escape. When she travelled to Era 14 she made sure that the Era 24's guns wouldn't kill the people of the past. She then planed to stop the war by placing 100 bombs under the command building. She regretted this action and went back to Era 24 to finish the war. (AUDIO: Legacy of Death)
