Cyber-Controller

A Cyber-Controller was a Cyberman who commanded lesser-ranking Cybermen, such as drones and Cyber-Leaders.

Hierarchy
Standing at the very top of the rigid Cyberman hierarchy, the Controller oversaw Senior Leaders who commanded Major Phalanxes including Leaders, Junior Leaders and the Cyber-Army. (PROSE: Attack of the Cybermen)

One Cyber-Controller was held by some accounts to be the singular, ultimate mastermind of the Cybermen; (PROSE: The Powers Behind the Throne) it directed its underlings from the Cyber-Tombs and, later from Cyber-Control. (TV: The Tomb of the Cybermen, Attack of the Cybermen) However, in other accounts, the Doctor was shown to encounter different individual Cyber-Controllers. (COMIC: The Cyber Empire, AUDIO: The Isos Network)

Individual Cyber-Controllers
A Cyber-Controller ruled the Mondasian Cyber-Empire. Unlike other Controllers, it appeared identical to its subordinates. However, it notably wore a cloak. (COMIC: Flower Power, The Cyber Empire)

The first invasion of Earth by the early CyberFaction was directed by a Cyber-Planner, known as the Cyber Module, who recognised the Second Doctor and Jamie McCrimmon from Planet 14; (PROSE: The Invasion, TV: The Invasion) years later, Jamie would remember the Cyber Module as a "Cyber-Controller". (COMIC: The World Shapers) Around the 1970s, a Telosian Cyber-Controller was activated on Isos II to lead a counter-invasion of Earth by the "Early" CyberFaction (AUDIO: The Isos Network) after the first one was repelled. (TV: The Invasion)

In 1986, a group of Cyber-Leaders led an invasion of Earth. One Cyber-Leader, Gern, declared himself Controller. Ultimately, however, the invasion ended in defeat when Mondas was destroyed. (PROSE: Doctor Who and the Tenth Planet, TV: The Tenth Planet)

In 2006, the Seventh Doctor met an early evolution of a Cyber-Controller on Earth: the Cyber Co-ordinator. (PROSE: Iceberg)

In 2011, a group of Cybermen - resembling the Cybus Cybermen of the Cyber Legions - who had reactivated after their ship crashed on Earth centuries prior, almost converted Craig Owens into a Cyber-Controller, but his "love" for his son overloaded their emotional inhibitors and caused them to explode, saving Craig from the complete process. (TV: Closing Time)

In the late 21st century, a Cyber-Controller led an attack on Space Station W3. Zoe Heriot brought the Cybermen into the Land of Fiction, and the Cyber-Controller, realising the potential of converting fictional characters, led an invasion there until Grendel's mother ripped its limbs off and the Lady of the Lake beheaded it. (AUDIO: Legend of the Cybermen)

One Cyber-Controller led the Cybermen in an incursion into a parallel universe, altering history to combine that universe with N-Space. In the 24th century, they encountered a species similar to their own called the Borg and they entered a temporary alliance, the Cybermen modifying themselves with Borg technology before betraying them. With the support of the Eleventh Doctor, the crew of the Starfleet vessel USS Enterprise-D formed an uneasy alliance with the Borg and stormed the Cyber-Controller's Cyber-ship. The Cyber-Controller was overcome and the Borg set all of the Cyber-ships to self-destruct through the Cyber-web that linked them together. (COMIC: Assimilation²)

In the 25th century, the Second Doctor and his companions Jamie McCrimmon and Victoria Waterfield found a Telosian Cyber-Controller in the Cyber-tombs of Telos, and it immediately took charge of the Cybermen. It intended to make the archaeological party the first of a new race of Cybermen, but was ultimately trapped when the Doctor and Toberman re-sealed the tombs. (TV: The Tomb of the Cybermen) On returning to Telos, the Sixth Doctor met this Cyber-Controller again, who had been reprocessed into a Cyberman similar to its subordinate CyberNeomorphs. The Cyber-Controller was behind a scheme involving time travel to ensure the destruction of Earth prior to Mondas's return to the solar system. A blast from a Cyber-gun fired by the Doctor killed him. (TV: Attack of the Cybermen)

A Cyber-Controller attended Bonjaxx's birthday party at Maruthea. (COMIC: Party Animals)

At an unknown point in time, a Neomorph Cyber-Controller on New Mondas was inspecting some converted Cybermen, along with a Cyber-Leader. However, the recently converted Cybermen, having been hijacked and fitted with Oblivion Continuums by a force of Silver Daleks, self-destructed, destroying the Cyber-Controller, the Cyber-Leader, and all of Cyber-Command. (COMIC: Cyber Crisis)

In the far future, a Cyber-Controller took the Cybermen back in time to the early 21st century to convert all the humans on Earth. It was killed by the Eighth Doctor, who used the Time Vortex to turn it into dust. (COMIC: The Flood) At the end of the universe, the Cybermen had been reduced to a single asteroid colony under another Cyber-Controller. (COMIC: Supremacy of the Cybermen)

Alternate timelines
In the alternate timeline of the "Cyberverse", on the planet Chronos in the year 3286, the Sixth Doctor encountered a version of his companion, Evelyn Smythe, who had become a Cyber-Controller when infected by a techno-virus created by her own future self. This Cyber-Controller planned to convert the Doctor himself into the next Cyber-Controller, but was killed by Reece Goddard. (AUDIO: Real Time, WC: Real Time)

In another alternate timeline, in the 27th century, a Telosian Cyber-Controller and a Cyber-Planner oversaw a Cyberman invasion of Krelos, which had been inadvertently been caused by Cyber-particles from the Second Doctor's archived TARDIS control room in the Fourth Doctor's TARDIS. Following the invasion of Krelos, the Cyber-Controller monitored the Cyber Time Squad's mission to 25th century Telos to capture the Fourth Doctor after he travelled there. However, the Doctor managed to avert this timeline by eliminating the Cyber-particles that had infected Jamie McCrimmon during his adventure to Telos with the Second Doctor. (AUDIO: Return to Telos)

In an alternate timeline where gave the Cybermen the means to conquer all of time and space, a Cyber-Controller, whose existence was unknown to Rassilon, secretly manipulated him into believing that he had full control of the Cybermen during the Gallifreyan Cyber Fleet's invasion of the Capitol on Gallifrey. This Cyber-Controller planned to accelerate the death of N-Space and rebirth it as the "Age of the Cyberiad", a universe under complete Cyber-control from its very beginning. Ultimately, the Controller was destroyed when the Twelfth Doctor and Rassilon used the regeneration energy stored in the Eye of Harmony to restore N-Space to its state before Rassilon had encountered the Cybermen; the Cyber-Controller, despite supposedly being emotionless, screamed in outrage as the timeline was reset. (COMIC: Supremacy of the Cybermen)

Parallel universes
On one parallel Earth, the Cyber-Controller of Hive Section 49 was activated, along with the rest of the Section, by the Machine, and travelled from the Hive to the laboratory of the UNIT base Fortress Island in N-Space via a dimension bridge formed from the virtual conversions of the Petronella Osgood, Vikram Shindi and Sam Bishop of N-Space. (AUDIO: Telepresence) Upon its arrival, the Cyber-Controller led the Cybermen's attempt to secure a foothold in N-Space as part of the Cyber-Mainframe's operation to upgrade the entire multiverse, overseeing the Cybermen's conquest of Fortress Island, and allying with the converted Osgood to develop a smartphone app to virtually-convert millions of humans across the Earth. (AUDIO: Code Silver) Ultimately, however, the Cyber-Controller, as well as all the other invading Cybermen, were destroyed by, after he was seemingly converted into the "Cyber-Master" and reprogrammed the dimension gate connecting to the parallel Earth to draw energy from all the universes the Cybermen had failed to secure a foothold in, thereby poisoning their power supply. (AUDIO: Master of Worlds)

On "Pete's World", John Lumic, creator of that universe's Cybermen, became a Cyber-Controller. (TV: The Age of Steel)

Behind the scenes

 * The credits list in The Tomb of the Cybermen lists the Controller slightly differently, as the "Cyberman Controller".
