Thalek (Brotherhood of the Daleks)

Thaleks were a powerful race that existed in an Alternate timeline in which The Doctor never left Gallifrey, they conquered half the Mutter's Spiral.

''Their name suggests relation to both Daleks and related to the Thals. It appears that in this timeline, it was the Thals, rather than the Kaleds, that became a powerful Cyborg race, becoming the equivalent of the Daleks in this timeline.''
