Cybermen

The Cybermen were a "race" of cybernetically augmented humanoids. They varied greatly in design, with different factions originating independently by parallel evolution on planets throughout time and space, including Mondas and Telos. Some Cybermen were born out of an instinct to survive, others hunger for immortality because their civilisations were dying out and they wanted to survive, and some the intent to upgrade themselves and everyone around them. (DW: The Battle of the Strong et al.)

Despite their evolution in design, there were similarities between most groups of Cybermen. For the most part, they lacked individuality or names. Cybermen had no emotions and viewed them as a weakness. They frequently attempted to physically and mentally re-engineer humansand other humanoids into Cybermen, via a process called "cyber-conversion" or "upgrading". (DW: The Enemy Uncovered, The Battle of The Strong)

General appearance
Though the Cybermen's designs varied greatly across time, space and universes, the many versions had several things in common. Nearly all were predominantly silver in colour, (DW: The Tenth Planetet al.) except for the Cyber-Scouts, who were completely black, (DW: Attack of the Cybermen)

Many Cybermen also exhibited exposed circuitry and tubing on a rubber or mylar-textured outer skin, (DW: The Tenth Planet et al.) although some Cybermen had entirely metal bodies with no exposed circuitry. (DW: The Enemy Uncovered, Battle of the Strong et al.)

Helmet
The head of a Cyberman was known as a Cyber-helmet, and was often characterised with a pair of side handles on the left and right-hand sides of the helmet, which connected together above the Cyberman's helmet. (TV: The Moonbase et al.) However, there were notable exceptions to this trait.

The CyberMondans possessed a third side handle connecting from the back of their heads. (DW: The Tenth Planet)

By contrast, some Cyber-Controllers lacked side handles, instead possessing enlarged craniums. (DW: The Tomb of the Cybermen, Attack of the Cybermen)

Other features
The CyberMondans of Mondas notably retained organic, human hands. (DW: The Tenth Planet)

Most other Cybermen were entirely covered by their metallic suits. (DW: The Moonbase et al.) Some partial conversions were known to exist that still held human features, among them Tobias Vaughn. (DW: The Invasion)

The Cybermen on the Moonbase and those released by Eric Klieg on Telos were slim and spoke in a monotone, buzzing voice, emphasising their lack of emotion. (DW: The Moonbase, The Tomb of the Cybermen)

The Cybermen who attempted to destroy Earth in 2526 had bulkier, more imposing forms and deeper voices. (DW: Earthshock) Similar Cybermen also existed in the 1980s, (DW:Attack of the Cybermen, Silver Nemesis)

The Cybermen who invaded Gallifrey were also rather bulky. (DW: The Enemy Uncovered, The Battle of the Strong)

Early Mondasian Cybermen had a quavering voice which put inflected syllables in a seemingly random, sing-song manner. Their suits were not entirely metallic, the face and hands being instead covered in a sort of hardened medical gauze. (DW: The Tenth Planet, Spare Parts, The Third Planet)

The Cybermen that invaded Gallifrey spoke in an electronic, monotone voice, far more emotionless and deeper than previous versions encountered by the Doctor. These Cybermen used technical terms like "compatible" and their battle cry, "DELETE!". (DW: The Battle of the Strong)

Conversion
Cyber-conversion was the process by which compatible beings were physically and mentally altered into Cybermen. This process was necessary for the Cybermen to increase in number and was carried out in many locations. (DW: Attack of the Cybermen)

Cyber-conversion could also be achieved by injecting an individual with Cyber nano-mites, which would slowly transform them into a Cyberman. (DW: The Third Planet)

Vulnerabilities
Different Cybermen had a verity of weaknesses.

The most notable was the element gold which, being non-corrosive, choked their respiratory systems, a property exploited by the glittergun used during the Cyber-Wars. (DW: Revenge of the Cybermen, Earthshock, Silver Nemesis)

On occasion, the mere touch of gold was toxic to them. Gold coins or gold-tipped arrows could destroy them. (DW: Earthshock, Silver Nemesis)

Other fatal weaknesses of the Cybermen included the combination of solvents known as Polly Cocktail, (DW: The Moonbase) and excessive levels of radiation, (DW: The Tenth Planet)

Cybermen affected by the Cerebration Mentor, an emotion-enhancing device, went "mad". (DW: The Invasion)

Bullets were unable to damage Cybermen. Explosives and bazooka shells took them down easily. (DW: The Invasion, Silver Nemesis) UNIT developed gold-tipped rounds to combat Cybermen. (DW: Battlefield) At close range, attacks with energy and laser weapons could kill Cybermen. (DW: Earthshock)

Raston Warrior Robots counted Cybermen among the many beings they could kill. Although equipped only with javelins and blades, the technology of the robots allowed them to easily destroy several Cybermen. (DW: The Five Doctors)

Cybermen could also be destroyed by rocket launchers. (MOV: Doctor Who: The Upgrade from Tomorrow)

Technology
The Cybermen forces in 2526 used the Cyberlance, a powerful, hand-held cutting weapon. They also used the Cyberscope, a device that allowed Cyber commanders to view the battlefield remotely and access a computer database (containing, among other data, information on their race's encounters with the Doctor). (DW: Earthshock)

Cybermen in 1986 had a built-in distress signal in their heads that could be activated manually. (DW: Attack of the Cybermen)

The head of Cybermen in 1873 contained a neural generation unit. When removed from the head and with a suitable power source, this unit could be adapted to transmit a signal to distances up to 200 light years. (DW: The Silver Turk)

The Cybermen's eyes in 1873 were photocell. (DW: The Silver Turk)

While the Cybermen were capable of time travel, (DW: Earthshock) it was still primitive, limited and even dangerous as late as the 30th century. (DW: Illegal Alien)

Weaponry
When they attacked Earth in 1986, Cybermen carried large, hand-held, energy weapons. (DW: The Tenth Planet)

On the Moon in 2070, Cybermen could produce arcs of electricity from their hands to stun, disable and kill. (DW: The Tomb of the Cybermen) They also possessed a cannon that could operate in the vacuum of space. The virus Neurotrope X was used by Cybermen to incapacitate humans. (TV: The Moonbase) Cybermats were sometimes used to spread this virus amongst a population. (DW: Revenge of the Cybermen)

In the 21st century, the Cybermen who attacked Space Station W3 had death rays built into their chest units. (DW: The Wheel in Space)

The Cybermen encountered by UNIT in the late 20th century displayed these same built-in death ray weapons. They also carried large rifles that emitted a flame for medium range combat on London's streets. They also possessed a megatron bomb that was capable of destroying all life on Earth. (DW: The Invasion)

The Cybermen who attacked the Nerva Beacon had their weapons built into their helmets. They were activated with the touch of a hand. (DW: Revenge of the Cybermen) Cybermen in 2526, the invaders of Voga and the Cybermen removed by a Time Scoop to the Death Zone had portable cyber-bombs capable of devastating a planet. (DW: Earthshock, Revenge of the Cybermen, The Five Doctors)

In time, the Cybermen came to favour the hand-held cyber-gun over the built-in weapon. (DW: The Invasion onwards)

The Mondasian Cybermen encountered by two versions of the Doctor from different universes had a powerful laser weapon built into their headframe. It emitted a thick yellow laser beam. (SWED: Metallmännen; POL: The Fall of Mondas)

Originally, the only weapons owned by the Cybermen of the 35th century were their electrified hands, (DW: The Battle of the Strong) but they later gained a small wrist-mounted energy weapon. (MOV: Doctor Who: Vengeance)

Culture
Cybermen made survival their central objective. Since they could not reproduce naturally, they needed to create new members of their population through cyber-conversion. At times they tended to focus on converting the population of Earth, at other times on simply destroying it. (DW: The Tomb of the Cybermen)

Cybermen tended toward covert activity, scheming and using human or other agents, cybermats or androids to act as their proxies until they deemed it necessary to appear themselves. (DW: Revenge of the Cybermen, Earthshock, Attack of the Cybermen)

Individuality and emotion
Throughout their history, Cybermen, for the most part, lacked individuality or names. This was a result of their emotions being removed during the conversion process. (DW: The Tenth Planet, et al.)

A few Cybermen had individual names such as Krang, (DW: The Tenth Planet) and Gramm. (DW: The Silver Turk)

Cybermen in positions of authority included the ground level Cyber-Leader who commanded a group of ordinary Cybermen. (DW: Earthshock, et al.) Cyber-Leaders were sometimes aided by a Cyber-Lieutenant. Immobile computer-like Cyber-Planners would sometimes make decisions and long-term plans. (DW: The Wheel in Space, The Invasion) The Cyber-Controllers, who possessed enlarged craniums, had the position of highest possible authority. (DW: The Tomb of the Cybermen, Attack of the Cybermen)

Cybermen no longer possessed emotions and viewed them as a weakness. However, several of the Cyber-Leaders displayed characteristics that could be linked to emotions such as anger, amusement, and, at times, smugness. (DW: Earthshock, Attack of the Cybermen, Silver Nemesis)

Origins
As Mondas travelled beyond the outermost planets of the solar system, conditions on the planet deteriorated. The Ninth Doctor and Janet Wells arrived on Mondas prior to the rise of the Cybermen. They discovered the survivors living in an underground city roughly on a parallel with Britain in the 1950s, although with more advanced technology. They witnessed the Mondasians slowly slide towards cyber-conversion, as the Faction had. The Mondasian cyber-conversion program was conceived by the cybernetic gestalt intelligence controlling Mondas as a solution to the planet's increasingly desperate situation. These early Cybermen were, however, plagued with serious design flaws and the conversion method proved very unstable as the biological systems of most of its unfortunate victims would fail soon after they were turned, causing most subjects to perish. The conversion project's chief scientist, Doctorman Allan, managed to discover a solution when the Doctor was captured by Mondasian police. By using data extracted from a forcibly biological analysis of the Doctor, she discovered an extra brain lobe unique to Time Lords, dedicated to mechanical and other bodily functions. She was able to replicate this trait into a new Cyberman prototype, greatly increasing the survival rate of the newly converted. The Doctor was horrified about his unwilling hand in the creation of the Cyber race, so much so that he tried to derail history by poisoning the Cyber-Planner before it could manage to convert the entire population, and afterwards he helped the Mondasians with starting a research program into how to undo the conversion process. However, after the Doctor and Janet's departure, it turned out his efforts were ultimately in vain as the Cybermen soon overpowered and converted the remaining Mondasians. (DW: Spare Parts)

Scouting Missions
Scout crafts were sent to find Earth's location. The first expedition to find Earth crash-landed in the mountains of Austria around 1873. However, due to the extensive damage sustained during the landing, they failed to report the location of Earth to Cyber-Control on Mondas, which was 200 light-years away. The Thirteenth Doctor made sure that all Cyber-Technology from the expedition was destroyed. (DW: The Silver Turk)

International Electromatics
At some point in the 20th century, the Cybermen established a base on the dark side of Earth's Moon. The Cyber-Planner had contacted the industrialist Tobias Vaughn, the head of the International Electromatics corporation. Vaughn installed mind control circuits in his company's appliances, paving the way for an invasion. He also grafted cybernetic arms onto several of his workers.

Vaughn had a Cyber-Planner installed in his office. The plot was uncovered by the newly formed UNIT and the Second Doctor, who helped avert the invasion on the Earth and at the Cyberman base on the Moon. The invasion fleet came to Earth when the planet was put under cybercontrol by radio waves from IE products, but it was destroyed in a chain reaction started by missiles fired by UNIT. (DW: The Invasion) The Cyber-conversion units as well as the bodies of the Cybermen and fallen UNIT soldiers from this invasion were were stored away by UNIT. (MOV: Doctor Who: The Upgrade from Tomorrow)

Mondas destroyed
The First Doctor met an advance force of Mondans near Snowcap Base in Antarctica. This force was to prepare for Mondas' return to the Sol system and to drain Earth's energy for the Cybermen. Mondas absorbing too much energy, combined with Hogan Cox setting of a nuclear blast on Mondas' surface destroyed the planet, as well as the Cybermen on Earth who depended on Mondas for power. (DW: The Tenth Planet, The Third Planet)

Aftermath
Another group of Cyberman attempted to establish a home planet away from Earth; eventually claiming the planet Telos as their new home. (DW: The Tomb of the Cybermen, Attack of the Cybermen; CF: Invasion)

Presence in the late 20th century
In November 1988, a scouting party was sent to Earth in search of a statue made of validium called Nemesis, a Time Lord weapon. The Cybermen met Lady Peinforte, who brought many of their number down with gold-tipped arrows. The Leader apparently forced the Seventh Doctor to surrender the Nemesis. Their force was destroyed by Nemesis as the Doctor had instructed. (DW: Silver Nemesis)

Attacks during the 2010s
In December 2018, exactly 32 years after Mondas returned to Earth, Cybermen who had been in hiding in the South Pole since the International Electromatics invasion attempted to sabotage the FLIPback project and take over the Earth in the ensuing chaos. With the help of Ruby Duvall, the Ninth Doctor and Janet Wells prevented the Cybermen from carrying out their plan and destroyed them. (DW: Iceberg)

2021 Cyberman invasion
Martin Amadeus, UNIT's new scientific advisor used the Cyber-conversion units UNIT had stored away to create an army of Cybermen. This new Cyber-army infiltrated the Valiant. Brad Zimmerman, an American UNIT soldier also aided Amadeus, and eventually forced the Twelfth Doctor to attach a homing device to his TARDIS console, which would summon a Cyber-invasion force. The Cybermen invaded Earth, but were defeated when Caitrin Ryan (who had been partialy converted with her emotions intact), activated a self-destruct sequence that destroyed the entire Cyber-fleet. (MOV: Doctor Who: The Upgrade from Tomorrow)

Late 21st century
By the late 21st century, the Cybermen were known and feared in several galaxies. but were thought extinct by Earth. At this time the Earth's weather was controlled by the Gravitron installation in the Moonbase. The Faction planned to use the Gravitron to disrupt Earth's weather and destroy all life on the planet. (DW: The Moonbase)

The Second Doctor became "known and recorded as an enemy of the Cybermen". Space Station W3 was the site of a takeover by the Faction, but were defeated by the Second Doctor. (DW: The Wheel in Space)

First Cyber-wars
The Cybermen eventually managed to destroy most of Voga, (DW: Revenge of the Cybermen)

Cybermen on Telos
The Brotherhood of Logicians financed Parry's expedition to find the cyber-tombs on Telos. Eric Klieg and Kaftan accompanied the expedition so that they could negotiate an alliance with the Cybermen. With the help of either the Second Doctor, Jamie McCrimmon, and Victoria Waterfield, the expedition found and opened the cyber-tomb. After the hibernating Cybermen were reawakened, the expedition realised the true danger of the Cybermen and the tombs were quickly resealed, despite the Cyber-Controller fighting to reopen the doors, (DW: The Tomb of the Cybermen) being damaged in the process. (DW: Attack of the Cybermen)

After a timeship landed on Telos, the Cybermen, led by the Cyber-Controller, captured it and formulated a plot to save Mondas by diverting Halley's Comet to Earth to destroy it in 1985. A party of Cybermen travelled back in time and established a command centre hidden in the London sewers from which they could affect the comet.

When the Sixth Doctor and Peri Brown visited London in 1985, the Cybermen captured the Doctor's TARDIS and forced him to take them back to Telos. Bringing the Doctor and Peri to Telos led to several losses for the Cybermen, including the death of the Cyber-Controller and the Cryons gaining help in their revolution against the Cybermen. (DW: Attack of the Cybermen)

Great Cyber-War
One group of Cybermen hounded the remaining fragment of Voga.

Centuries" after the Cyber-Wars, the ship pursuing Voga finally caught up to the planet, now in orbit around Jupiter, and infiltrated the nearby Nerva Beacon to launch their plans. The Cybermen’s attempt to destroy it was defeated and their craft and themselves destroyed due to the involvement of the Fourth Doctor, Sarah Jane Smith, and Harry Sullivan. (DW: Revenge of the Cybermen)

Great Cyber War of the 26th century
the 26th century saw a re-ignition of conflict between Cybermen and humanity.

In 2526, several planets began to unite to oppose the Cybermen in a war. A force of Cybermen tried to devastate Earth on the eve of their conference to finalise the alliance, intending to detonate a Cyberbomb and convert the survivors. After the Fifth Doctor thwarted this plan, they hoped to crash a freighter into Earth and cause an ecological disaster. Although the effort failed, the freighter was catapulted back in time to become the "meteor" that wiped out the dinosaurs. (DW: Earthshock)

Cyber-Wars survivors
In the 30th century, a group of Cybermen of the "Late" CyberFaction, with limited time travel capabilities, attempted to invade Earth in 1940. They were stopped by the Eighth Doctor, Henrick and Bernice Summerfield. (DW: Illegal Alien)

Mission to save Mondas
In 3305, the Cybermen attempted to save Mondas again by stealing the Doctor's TARDIS. They achieved this by silently invading Earth, which they knew would eventually lure the Doctor in. When the Fourteenth Doctor, Raleigh Baker-Mitchell and Pete Fletcher arrived on Earth in 3307 and began helping a resistance group, the Cybermen launched an attack, with a large army of Cybermen eventually succeeding in stealing the TARDIS (along with a group of surviving humans.

The Cybermen soon made an alliance with the Master, who agreed to help them save Mondas. The Cybermenm traveled to the South Pole in 1986. The Cybermen were eventually defeated by the newly regenerated Fifteenth Doctor, Zenla and Caitrin Ryan. The remaining Cybermen in 3307 were defeated by Raleigh and Pete. (DW: Remembrance of the Gaians, The Third Planet)

Undated events
A Cyberman was among the life-forms exhibited in Vorg's Miniscope. (DW: Carnival of Monsters)

During the Dark Times on Gallifrey, the Cybermen were excluded from the games in the Death Zone, because the Time Lords believed they had an unfair advantage over other victims of the games. Borusa, having found the Game of Rassilon, transported a squadron of Cybermen to the Death Zone to threaten and harass the Third Doctor and Sarah Jane Smith. These Cybermen were destroyed by a similarly transported Raston Warrior Robot. A second squadron allied with the Master, intending to stage an invasion of Gallifrey, but he betrayed and destroyed them. A third squadron attempted to destroy the Fifth Doctor's TARDIS, but were foiled when the TARDIS dematerialised at the last second. (DW: The Five Doctors)

To be added. (DW: The Lords of Time)

Due to time distortions, a group of Cybermen were suddenly transported on to Omega's ship on the day of his time travel experiment. The Cybermen attempted to kill the Tenth Doctor, Sandra Armstrong and Omega, but were defeated by two UNIT soldiers, who suddenly appeared. (MOV: Doctor Who)

Legacy
While on trial for breaking the Time Lords non-interference policy, the Second Doctor used a Thought Channel to show them some of the evils he'd fought against, one of which was a Cyberman. (DW: The War Games)

The Tenth Doctor wrote about the Cybermen in a manuscript about his life. He later showed Sandra Armstrong the memory of his, Jamie and Victoria's encounter with the Cybermen in their ice tombs on Telos. (DW: The Name's Shakespeare, William Shakespeare)

The Twelfth Doctor kept part of a Cyberman chest plate in the TARDIS within the C chest. (DW: The Unicorn and the Wasp)

While in the Virtual Simulation reliving his past, the Thirteenth Doctor relived the invasion of Gallifrey by the Cybermen in 3447. (DW: Now Those Days Are Gone)

Alternate versions
In a universe that was formally part of the Toymaker's Realm, Mondas returned to the Sol system in 2019 and the Cybermen attacked a base belonging to FARA, that universes' version of the United Nations Intelligence Taskforce. The Cybermen also made an alliance with the Bemästra. (SWED: Metallmännen)

In another universe that was also formally part of the Toymaker's Realm, Mondas returned to the Sol system in 2019, but was already on the brink of destruction, due to the Cybermen's experiments. The Cybermen attempted to invade Earth in an attempt to claim it as their own home planet, but eventually became trapped on a dying Mondas. (POL: The Fall of Mondas)

Miscellaneous

 * An episode of the long-running BBC medical soap opera Casualty featured a young boy wearing a Cyberman helmet and gloves.

Development
The idea for the Cybermen came from Kit Pedler's interest in new medical advances and his fears of where they might lead. Early concepts of the Cyberman design emphasised the "man" part of the name, but the proposed design would have cost too much money. Indeed, the televised version of The Tenth Planet featured much more human-like Cybermen with human hands.

The second appearance of the Cybermen in The Moonbase (pre-planned by the production team even before The Tenth Planet had aired), re-designed them radically, making them much more robotic in appearance. The Cybermen went through another major re-design in The Invasion, yet another in Earthshock, one in Illegal Alien, one in the first movie and another one in Remembrance of the Gaians.

Telos and Mondas
Much as The Daleks killed off what appeared to be the entire Dalek population at its climax, The Tenth Planet ended with the apparent destruction of the newly-introduced Cybermen and their planet, Mondas. When the Doctor, Ben and Polly met Cybermen again in The Moonbase, they had a noticeably different appearance. A baffled Ben protested that "the Cybermen were all killed when Mondas blew up, weren't they?", to which the Doctor merely replied "Or so we thought". The story did not weigh in further on how these Cybermen related to the very different cyborgs seen in The Tenth Planet.

The Tomb of the Cybermen, the third televised Cyberman story, featured Cybermen identical to those of The Moonbase and made no mention of Mondas and its destruction. The Cybermen's homeworld was rechristened "Telos" and was now presented as still in existence long after the 20th century.

The matter was confused in 1975 by Revenge of the Cybermen, which referred to Mondas once again as the Cybermen's original homeworld while having the band of Cybermen seen in the story also acknowledge the existence of Telos as a planet under their control. This reversal of what had become the accepted explanation for Tomb of the Cybermen 's retcon was carried over in 1983 with Attack of the Cybermen, which unambiguously presented Telos as a foreign world which the Mondasian Cybermen had colonised following the loss of their original homeworld
