Pureblood Sontaran

The Pureblood Sontarans were a group of Sontarans. They were natural-born members of their species and did not usein their race's mass cloning techniques.

History
A colony of Purebloods were convinced by the Rutan Host that their kind had abandoned them and had plans to subjugate them. Angered, this colony of Purebloods attempted to exterminate their clone relatives until the Seventh Doctor showed them they were only being used by the Rutans, who planned to kill the remaining Purebloods once they had accomplished their goal.
