Cyberslaves were humans converted into cyborgs by a Nanoform infection from Cybermats. Their body was human in shape but metallic, completed with a Cyber-Helmet. They were also able to attack by firing lightning out of their hands. After the Cyberman army and the Cyber-Lord awoke, the Cyberslaves were deemed unnecessary and that they had fulfilled their purpose and were all destroyed, including Elizabeth Meadows. (VG: Blood of the Cybermen)Chiholm had been infected due to a Cybermat biting him. The Cyberslave conversion process takes at least 50 minutes. As they are only slaves they aren't as intelligent as other species, including Cybershades. Their only thought is death and orders. It is said that one day they will return.
