Graff (Genetics of the Daleks)
From Tardis Wiki, the free Doctor Who reference
Graff was the captain of Starship Future. Her life cycle was increased so that she would not need to be put in suspension. She thought that the Fourth Doctor was the cause of the missing supplies, but after Erica Swann tried to use him as a scapegoat and the Dalek escaped, she began to trust him. She tried to get the Dalek Mutants to an airlock to expel them into space and killed herself in the process. (AUDIO: Genetics of the Daleks)
