Cyber-Lord (The Next Doctor)

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

Appearance
The Cyber-Lord had a cyber-suit similar to standard Cybermen. His cyber-helmet, however, had black handle bars, a black face plate and a transparent "window" through which his brain could be seen, (TV: The Next Doctor) similar to the Cyber-Controller. (TV: The Age of Steel)

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 labour necessary to build the CyberKing, and in return promising her liberation, and exception from Cyber-conversion.

The Cyber-Lord eventually betrayed Hartigan, placing her in the CyberKing'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 decided to make her own race of Cybermen. The Cyber-Lord objected and attempted to remove her from the throne, but Miss Hartigan used her new powers to destroy the Cyber-Lord for treason. (TV: The Next Doctor)
