Cyber-Lord (The Next Doctor)

The Cyber-Lord was the commander of the Cybermen, a form of Cyber-Leader.

Appearance
The Cyber-Lord had a suit similar to standard Cybermen. Its helmet, however, had black handle bars, a black face plate and a transparent "window" through which its brain could be seen, similar to the Cyber-Controller. (DW: The Next Doctor)

History
A Cyber-Lord was among the Cybermen that ended up in 1851. After establishing a base in London, the Cyber-Lord forged an alliance with Mercy Hartigan, using her to gather the child labor necessary to build the Cyber-King, and in return promising her liberation, and exception from Cyber-conversion.

The Cyber-Lord eventually betrayed Hartigan, placing her in the Cyber-King's control throne, and explaining that by becoming Cyber-King, Hartigan would receive her liberation from the anger, hatred and rage in her mind. However, Hartigan proved too strong-willed for the conversion; her mind was too powerful to control, and she used her new powers to destroy the Cyber-Lord. (DW: The Next Doctor)

In A Good Man Goes to War A hand is shown using the Doctor's Sonic Screwdriver to lock one door as the ship suddenly begins to shake. A group of Cybermen raise their weapons at a door which is about to open. As Amy - in the voice over - says "...the Last Centurion.", Rory walks up to the Cybermen. He says he has a message and a question. A message from the Doctor, and a question from himself. "Where is my wife?!" As the Cybermen remain silent, he reacts - "Oh, don't give me those blank looks." - and reveals knowing that the CyberLeague monitors everything in that galactic quadrant. The Cyber-Lord asks what the message is. Rory is silent, as the rest of the CyberLeague's vessels explode except one. "Would you like me to repeat the question?"
