CyberNomad

The CyberNomads were groups of Cybermen that split off from the CyberFaction in the Second Cyberman Divergence some time after the destruction of Mondas. While the CyberFaction stayed within the Sol system, the CyberNomads ventured out into the Mutter's Spiral. (REF: Doctor Who: Cybermen)

History
Sometime after the Cyber-Wars, a ship of CyberNomads attempted to destroy Voga. They were defeated by the Fourth Doctor and destroyed by the Vogan missile Skystriker. (DW: Revenge of the Cybermen)
 * The Doctor described Cybermen as "total machine creatures" and the Cyber-Leader stated he had enough parts to build a new Cyber-army. This may imply that CyberNomads, or perhaps Cybermen on the whole, were entirely robotic at this point in history.

Sometime before the 26th century, a group of CyberNomads discovered frozen CyberTelosians, resulting in the CyberNeomorphs. (REF: Doctor Who: Cybermen)
