Cyber-Lord (The Next Doctor)

A Cyber-Lord was a form of Cybermen, similar in rank to a Cyber-Leader.

Appearance
The Cyber-Lord had a similar suit to a 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.

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 too powerful to control, and she used her new powers to destroy the Cyber-Lord. (DW: The Next Doctor)
