Cyber-Leader (A Good Man Goes to War)

A Cyber-Leader commanded the Twelfth Cyber Legion. It had black handle bars on its helmet, but also had a black face and a transparent "window" through which its brain could be seen, similar to the Cyber-Lord of Pete's World. (TV: The Next Doctor) Rory Williams went to the Cyber-Leader's Cyber Ship and confronted it to learn the location of Demon's Run. Part of the fleet was then destroyed by the Eleventh Doctor, just to make a point to the Church's Anglican Marines and the Cybermen. (TV: A Good Man Goes to War)

Along with a Cyber-Planner, the Ninth Cyber Legion was commanded by a similar-looking Cyber-Leader although its brain was not visible. (GAME: The Eternity Clock)
