Cyber-Leader

This Cybermen from Pete's World designated a Leader when they invaded Earth in our universe in 2007.

The Cyber-Leader was identified by black handle bars on its helmet. When the Leader was destroyed, the information it had was downloaded into another Cyberman who would be upgraded to Cyber-Leader. The first leader during the battle Of Canary Wharf was destroyed by the Preachers whilst the second was slain by Yvonne Hartman in her converted form. (DW: Army of Ghosts / Doomsday)

There was another Cyberleader who turned up in 1851, this leader had black handle bars and a redesigned black face plate with a transparent "window" through which its brain could be seen. This Cyberleader was destroyed by the CyberKing. (DW: The Next Doctor)
