Cyberslave

Cyberslaves were humans converted into shambling cyborgs by a nanoform infection from Cybermats.

Characteristics
Their bodies were human in shape but metallic, completed with a Cyber-helmet. They were able to attack by firing lightning out of their hands. The Cyberslave conversion process took at least fifty minutes. As they were only slaves, they weren't as intelligent as other races, making them similar to Cybershades. Their only thoughts were death and orders. (GAME: Blood of the Cybermen)

History
After the Cyberman army and the Cyber-Lord awoke, the Cyberslaves were deemed unnecessary and their purpose fulfilled. They were all destroyed, including Elizabeth Meadows. (GAME: Blood of the Cybermen)

Other references
Cyber-drones, which were created on Centuria by Cybermen descended from those created in Pete's World, were also refered to as Cyberslaves. (COMIC: The Power of the Cybermen)
