Thalek (Auld Mortality's universe)

In a parallel universe, the Thaleks were a race that conquered half of Mutter's Spiral. Their war cry was "Annihilate!".

The Doctor of this universe was worried about their actions and the fact that the Time Lords did nothing to stop them. He later encountered them during his travels, after he left Gallifrey. (AUDIO: Auld Mortality)

The Doctor and Susan once brought a group of Thaleks to Trafalgar Square. The Thaleks wanted to feed some pigeons. (PROSE: The Innocents)

Behind the scenes

 * The Thaleks were created as a Doctor Who Unbound counterpart for the Daleks, although another Unbound counterpart for the Daleks, native to the Unbound Universe, would later be introduced in AUDIO: Masters of War. Both races were warrior races, had a similar battle cry and were seen as a threat to their universes by their respective Doctors. As the name is a portmanteau of the Daleks' name and that of their ancestral enemies the Thals, the implication is that in the absence of a wandering Doctor, it was not the Kaleds or Dals, but rather the Thals, who developed into Dalek-like creatures.
 * According to the notes of Lungbarrow, in an earlier draft of Auld Mortality, the Thalek's chant was "Excommunicate!"
