Cyber-Leader

The Cyber-Leader is one of the highest ranks of Cyberman, and apparently the ultimate leader when the Cyber-Controller is not present.

The Cyber-Leader is distinguished from other Cybermen by either a black head (for Mondasian Cybermen) or black handle bars on the head (for Pete's World Cybermen). (DW: Attack of the Cybermen, Army of Ghosts / Doomsday)
