Cyberslave

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.
