Amstron guard
From Tardis Wiki, the free Doctor Who reference
Amstron guards served as security on the Great Wheel, the mothership of the Amstrons. In 2015, they detected the intrusion of the Eleventh Doctor, John Jones and ARC and intercepted them at the entrance to the Amstron sacred library. They would have terminated the trip if ARC did not immobilise them. (COMIC: The Eternal Dogfight)
