Twelfth Cyber Legion

The Twelfth Cyber Legion was a Cyberman fleet that monitored their local galactic quadrant. It was positioned twenty thousand light years away from Demon's Run. Rory Williams went to the head Cyber Ship to learn the location of Demons Run from the Cybermen. All the ships, except the one Rory was on were 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. 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)
