Dalek Supreme (The Doctor Strikes Back)

The Dalek Supreme was on his way to supervise the production of thousands of Dalek War Machines on an Earth-like planet in 2135, which was infiltrated by the Second Doctor. The Doctor went to moved to sabotage the production, but was spotted leaving his Homemade Dalek casing and was forced to flee. The Daleks searched for him and, unable to tell which one was the impostor, began destroying each other. The Dalek Supreme contacted them from his Dalek flying saucer and ordered them to stop, but the Doctor then impersonated the Dalek Supreme and ordered the Daleks to destroy themselves. The Doctor escaped in the TARDIS just before the Dalek Supreme arrived, having struck a devastating blow against the Daleks. (COMIC: The Doctor Strikes Back)
