The Hostess
From Tardis Wiki, the free Doctor Who reference
The Hostess was presenter of a strange television programme in 1984. She kidapped people to partake in the game show to collect crystals for her ship. She kidnapped Vislor Turlough and Tegan Jovanka for this task. The Fifth Doctor thought that she was Kamelion, which was partially true as she was using him as an avatar. (AUDIO: Power Game)
