Human (Mindgame)

This human was a mercenary who fought for money and survival. An unknown alien took her, the Sontaran Sarg, an unnamed Draconian, the commander of the Brigade Merq, for experiments, hoping to learn their strengths and weaknesses. The human eventually killed the unknown alien and got herself and and her fellow prisoners back where they had came from. (HOMEVID: Mindgame)

She later died by taking her own life in a failing solo spacecraft after a total systems failure. (HOMEVID: Mindgame Trilogy)

Behind the scenes

 * In Mindgame, the unnamed human mercenary was strongly implied to be an older version of the Seventh Doctor's companion Ace, likewise played by Aldred. However, her identity was considerably more ambiguous in Mindgame Trilogy.
