Cyber-Leader

The Cyber-Leader is the supreme leader of the Cyberman, depending if the Cyber-Controller is present or not. Cyber-Leaders are sometimes accompanied and assisted by a Cyber-Lieutenant.

Cyber-Leaders are stronger than normal Cybermen. When attacked with gold, they have been shown to be more resistant.(DW:Silver Nemesis)They are designated as the Leader by either a black helmet,(DW: Revenge of the Cybermen), or black handle bars on their helmet.(DW: Attack of the Cybermen,Silver Nemesis)

The Cybermen from Pete's World did not designate a Leader until they invaded Earth in our universe in 2007. The Cybus 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 become the new Leader.(DW: Army of Ghosts / Doomsday)
