Twelfth Cyber Legion

The Twelfth Cyber Legion was a Mondasian Cyberman fleet that monitored their local galactic quadrant. It was positioned twenty thousand light years away from Demon's Run when part of the fleet was destroyed by the Eleventh Doctor, just to make a point to the Church's Anglican Regiment before he invaded the asteroid station to save Amy and Melody Pond. Rory Williams went to a Cyber Ship to learn the location of Demons Run from the Cybermen. Despite not having emotions, they seemed to fear the Doctor enough to give into his demands or they simply saw that they were not in a logical position to refuse. (DW: A Good Man Goes to War)
