Sixth Doctor (android)
From Tardis Wiki, the free Doctor Who reference
In the Warrior's universe, an android based on a version of the aberrant Sixth Doctor was created by Styggron. The android claimed to be the Doctor, rejecting the Time War, but used its likeness of the Warrior, acting Lord President, to gather an army of Shobogans to infiltrate the Capitol and depose the Warrior in order to make Styggron the President.
The Warrior revealed the android to be an impostor and used the Relics of Rassilon to destroy the Kraal fleet, and was able to create a similar android of Romana to track down and kill Styggron. (AUDIO: The Difference Office)
