Cyber-Controller (The Tomb of the Cybermen)

A Cyber-Controller directed lesser-ranking Cybermen and Cyber-Leaders from the Cyber-Tombs and, later from Cyber-Control.

Biography
In the 25th century, the Second Doctor and his companions found the Cyber-Controller in the Cyber-Tombs, and he immediately took charge of the Cybermen. He told the archaeological party they would become the first of a new race of Cybermen.

Using a Cyber-gun, Eric Klieg tried to hold the controller hostage when it was low on power, but he was unsuccessful.

Toberman, a partially cyber-converted human attacked the Controller after he killed Kaftan after she had fired on him with her gun, just before the Doctor sealed off the Cyber-Tombs, freezing the Cybermen once more. (TV: The Tomb of the Cybermen) On returning to Telos, the Sixth Doctor met the Cyber-Controller again, this time in a more advanced body. A blast from a cyber-gun fired by the Doctor killed him.

Appearance
Taller than the others, the Controller found in the Cyber-tombs on Telos had an enlarged, dome-shaped semi-transparent brain case lit from the inside. He also lacked the Cyberman chest unit and the Cyberman head handles, and his head was grey instead of silver. The Cyber-Controller had such authority that, upon awakening, the other Cybermen appeared to salute him. (TV: The Tomb of the Cybermen) Later, when he co-ordinated actions from Telos, the Controller had changed physically, now having changed to resemble the other Cybermen of that era. He had a chest unit, but still lacked the Cyberman head handles. He also now had a metal, though still enlarged, brain case. (TV: Attack of the Cybermen)
