Judoon

The Judoon were a race of rhinoform humanoids from the planet Judoonia, frequently employed as a mercenary police force. They were known to be brutish and single-minded in carrying out their tasks, without regard for unintended consequences of their actions.

Described as rhinoform bipeds, (AUDIO: Judoon in Chains) Judoon were two-metre high humanoids with stocky builds and rhinoceros-like heads. They had large lungs and could breathe even in environments with low levels of oxygen. They were resistant to even harsh physical assault, such as being hit with a marble statue. (TV: Smith and Jones) Judoon had yellow blood. (TV: Prisoner of the Judoon) They also had rather small brains; a Judoon brain was able to fit in a chest that could easily be held in a humanoid palm, or fit in a teaspoon. (WC: Prequel: A Good Man Goes to War, AUDIO: Judoon in Chains) The Judoon had canines, incisors, molars and pre-molars - the teeth of an omnivore, which meant they ate meat and vegetables. (WC: Teeth and Eating)

The Judoon were known for their strict obedience to the law and their brutal efforts in maintaining it. Crimes like physical assault towards a Judoon incurred the death penalty, without chance for trial. The Tenth Doctor described them as logical, but stupid, and they seemed to favour methodical patterns of behaviour to a fault. (TV: Smith and Jones) Even on crucial missions, Judoons would obey local laws and signs, including traffic laws and "Authorised personnel only" and "Pay and Display" signs. Similarly, they would follow mission procedure rigidly and always get a form signed when commandeering transport. The Judoon were trained to use all known forms of transit, albeit not very well in the case of cars. (TV: Prisoner of the Judoon) Their strict compliance with an established order even made them despise development even with their culture, and those who went out of their norms were often ostracised.
