Cyber-Lord (The Next Doctor)

=The Cyber-Lord= The Cyber-Lord was the leader of the Cybermen in the The Next Doctor

From TARDIS Index File, the free Doctor Who reference.
=Profile= The Cyberleader turned up in 1851, although this design of Cyberleader was actually known as a CyberLord. This leader had black handle bars and a redesigned black face plate with a transparent "window" through which its brain could be seen.

In the throne chamber, Hartigan is told by the Cyberlord that she will be the Cyberking, not the Cyberleader as she assumed. The Cyberlord explains that by becoming Cyberking, Hartigan will receive her liberation from the anger, hatred and rage in her mind. However, Hartigan proves too strong-willed for the conversion; her mind is too powerful to control, and she uses her new powers then the Cyberlord was destroyed by the CyberKing. (DW: The Next Doctor)
