Tenth Drax
The Tenth Drax was one of Inspector McCormick's "half a dozen best men". The second female incarnation of Drax, she had undergone a heart bypass operation three regenerations before to prevent anyone picking up her the beats of her hearts.
As such, she was present when McCormick was called to arrest the third, fifth, ninth and twelfth incarnations of Drax. They later all ran away in McCormick's TARDIS. (AUDIO: The Trouble with Drax)
At the funeral of Drax, she posed gilted widow Mimi who shot him, and said that Romana was the lover he left him for. The Eighth Doctor questioned her after the Valtrassi attacked, sending them to their Seventh Drax. She was supposedly shot and her heart bypass surgery fooled Liv Chenka to thinking he was dead.
