The Cyber Controller was first seen in The Tomb of the Cybermen where he had returned with the surviving Cybermen to Telos, their adopted planet. To insure that the Cyber race survived he instructed the remaining Cybermen to build tombs so that they could all be frozen to preserve their power supply.
The Cyber controller has a larger, dome shaped brain case. The Cyber Controller also appears taller than the other Cybermen and lacks the Cyberman chest unit. The Cyber Controller is the highest ranking Cyberman.
This Cyber Controller only appeared in the 1967 story The Tomb of the Cybermen.
