The Cyber-Controller is the semi-recurring antagonist in the long-running TV show Doctor Who. The Cyber-Controller is a model of Cyberman that commands lesser Cyber Units and often appears as the main antagonist in arcs featuring the Cybermen as the antagonists. It first appeared in the 1967 episode, "The Tomb of the Cybermen".
In his second incarnation, the Doctor encountered a Cyber-Controller who with his forces entered hibernation on their new home world Telos. They slept for 500 years, having arranged for their revival by an archeological party sponsored by the megalomaniac Eric Klieg who intended to use the Cybermen to conquer Earth. However, the Cyber-Controller casually overpowered him and revealed his plan and that they would become new Cybermen. However the Archeologists were saved by the ships crew, finding themselves trapped down below once the entrance to the tombs was sealed. The Cyber-Controller had them release the Cybermats. This failed thanks to the doctor managing to disable them.
However, Klieg regained control, having stolen one of the Cybermen's weapons and tried to negotiate with them. As power levels were low, the Cyber-Controller sent the rest of the Cybermen back into hibernation. Emerging on the agreement for being recharged, he returned Kaftans servant Toberman (who was now secretly partially converted and under his control). The Doctor tried to imprison him in the recharging booth, but the Cyber-Controller simply broke out. Revealing he had lied, he killed Kaftan. However the doctor convinced Toberman to turn on him. Using his mechanical enhancements, Toberman attacked him from behind and seemingly destroyed the Cyber-Controller. Later after re-imprisoning the cybermen, and fixing the doors so that they would electrocute anyone to stop anyone else getting in. The Doctor and the others tried to escape, however the still alive Cyber-Controller re-awoke and attacked them. They tried to close the doors on him, but they had to stop when they realized that the electricity would kill them the moment the door shut. However despite this Toberman managed to push them shut, killing him and seemingly killing the Controller as well.
Later in "Attack of the Cybermen" it was revealed the Cyber-Controller had survived, he rebuilt the cybermen, was rebuilt himself. And formulated another plan, to use time travel to 1985 divert Halley's Comet into the earth, damaging it to much, to stop there original home planet Mondas from being destroyed in 1986. However his plan was foiled once again by the doctor. Who was in the end forced to personally shoot him, while trying to save Lyton from being converted. This time he apparently was destroyed.
In "Closing Time" the Cybermen try to convert the Eleventh Doctor's companion Craig Owens into the Cyber Controller. They nearly succeed by draining his emotions however he reversed the conversion when he heard his baby crying for him and he regains his emotions. He also restores all the other Cybermen's emotions which destroys them and their ship.
