Rutan Host

The Rutan Host, or Rutans, are a fictional  extraterrestrial race from the British science fiction television series Doctor Who. They have long been at war with the Sontaran Empire, and this war dominates both cultures to the exclusion of all else. The Rutans only appeared on television in the serial Horror of Fang Rock, in which a single Rutan is encountered, though they are mentioned in some serials featuring Sontarans (The Time Warrior, The Sontaran Experiment and The Two Doctors).
