Tanya Webster
From Tardis Wiki, the free Doctor Who reference
Tanya Webster was an individual who was created from Ice Warrior DNA found by the Webster Corporation. She was half Human and half ice warrior and was forced to pilot the Ares One mission for NASA. Her involvement was considered troubling, however all was revealed to the Doctor as he realised that Tanya was a bargaining method for Paul Webster in order for him to escape Mars.
After an eventful mission, Peri Brown was surprised to hear that Tanya would stay with the Ice Warrior guardians to learn about their science. (AUDIO: Red Dawn)
