Cyber-Leader (Revenge of the Cybermen)

A Cyber-Leader was in command of some CyberNomads on an ancient Cyber-ship.

The Voga account
The Cyber-Leader attempted to destroy the planet Voga, to eliminate its gold reserves and therefore prevent the production of glitterguns in future conflicts the Cybermen already planned. After its plan of planting bombs in the core of Voga failed, the Cyber-Leader planned to ram the space station Nerva Beacon into Voga in a last attempt to destroy the planet completely so its gold would no longer be a threat. The Cyber-Leader was killed when the ship was destroyed by the Vogan rocket Skystriker. (TV: Revenge of the Cybermen)

Legacy
This Cyber-Leader was among the foes whom the Fourth Doctor saw call out to him in his mind shortly before his fall from the Pharos Project radio telescope, which resulted in the Fourth Doctor's regeneration. (TV: Logopolis)
