The Cybermen of the Doctor's universe were a race of artificially modified humans who originated from the planet Mondas, Earth's twin planet. The reason behind their modifications was due to the increasingly cold atmosphere of their planet. (TV: The Tenth Planet)
Their original goal was simply to return Mondas to the solar system; they would destroy the Earth and have Mondas replace it. The Doctor's first and sixth incarnations prevented this, and their attempt to destroy earth with a comet. (TV: The Tenth Planet, Attack of the Cybermen)
With nothing else left to them, the Cybermen took it as their primary aim to conquer the universe, converting where possible to boost their numbers. Fear of such conversion was prevalent on many worlds and so the Cybermen came to be objects of terror. (TV: Attack of the Cybermen)
Many species fought against them in the Cyber-Wars. (TV: Earthshock, Revenge of the Cybermen) After the wars were over, they had upgraded their technology, which overcame many weaknesses present in their original models. (TV: Nightmare in Silver, Death in Heaven)
The Cybermen were cybernetically augmented humanoids. Though they varied greatly in design over time (most likely due to the technology available to them), the many versions had several things in common. Nearly all were silver in colour, except for a black variety in the London sewers. (TV: Attack of the Cybermen, et. al)
All other Cybermen were entirely covered by their metallic suits. (TV: The Moonbase onwards) Some partial conversions were known to exist that still held human features, among them Tobias Vaughn. (TV: The Invasion)
The Cybermen on the Moonbase and those released by Eric Klieg on Telos were slim. (TV: The Moonbase, The Tomb of the Cybermen) The ones which infiltrated Briggs' freighter in 2526 had bulkier, more imposing forms. (TV: Earthshock) Cybermen like these also existed in the 1980s. (TV: Silver Nemesis)
Mondasian Cybermen had a quavering voice which put inflected syllables in a seemingly random, sing-song manner. (TV: The Tenth Planet) Later Cybermen spoke in more of a monotone, emphasising their lack of emotion. (TV: The Moonbase)
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 at many locations. (TV: Attack of the Cybermen)
A great weakness of the conversion was they could only convert species close to humans. This left Time Lords like the Doctor safe for a time. (TV: Closing Time) However, the post-Cyber Wars variety no longer had this drawback, and were able to temporarily incorporate his mind to create the Cyber-Planner Mr Clever. (TV: Nightmare in Silver) A further upgrade to their process was being able to convert corpses, no matter how decayed or what age the victim died at. (TV: Death in Heaven)
Cybermen had major 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. (TV: Revenge of the Cybermen, Earthshock, Silver Nemesis) (AUDIO: Last of the Cybermen) On occasion, the mere touch of gold was toxic to them. Gold coins or gold-tipped arrows might destroy them. (TV: Earthshock, Silver Nemesis) Gold also blocked their sensors and caused the cybermats to malfunction. (PROSE: Revenge of the Cybermen)
20th century guns could damage Cybermen, but did not kill them. Explosives and bazooka shells took them down easily. (TV: The Invasion, Silver Nemesis) UNIT developed gold-tipped rounds to combat Cybermen. (TV: Battlefield) At close range, attacks with energy and laser weapons could kill Cybermen. (TV: 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. (TV: The Five Doctors)
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). (TV: Earthshock)
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. (AUDIO: The Silver Turk)
While the Cybermen were capable of time travel, (TV: Earthshock, AUDIO: The Reaping) it was still primitive, limited and even dangerous as late as the 30th century. (PROSE: Illegal Alien) Should the Cybermen have mastered time travel, they would have become strong enough to crush the Draconians, the Sontarans, the Time Lords and even the Daleks. (WC: Real Time, AUDIO: Real Time)
Weapons (short range) Edit
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. (TV: The Invasion)
Weapons (other) Edit
Cybermen in 2526, the invaders of Voga, and the Cybermen removed by Time Scoop to the Death Zone had portable cyber-bombs that could devastate planets. (TV: Earthshock, Revenge of the Cybermen, The Five Doctors)
Cybermen made survival their central objective. Since they could not reproduce naturally, they needed to create new members of their population by other means, via cyber-conversion. At times they tended to focus on converting the population of Earth, at other times on simply destroying it. (TV: The Tomb of the Cybermen)
Cybermen tended toward covert activity, scheming from hiding and using human or other agents, cybermats or androids to act as their proxies until they deemed it necessary to appear in person. (TV: Revenge of the Cybermen, Earthshock, Attack of the Cybermen)
Individuality and emotion Edit
- In the script and cast listings for The Tenth Planet the individual Cybermen had names. They were Krail, Talon, Shav, Krang, Jarl and Gern. (REF: Doctor Who: The Encyclopedia)
Cybermen in positions of authority included the ground level Cyber-Leader who commanded a group of ordinary Cybermen. Cyber-Leaders were sometimes aided by a Cyber-Lieutenant. Immobile computer-like Cyber-Planners would sometimes make decisions and long term plans. (TV: The Wheel in Space, The Invasion) The Cyber-Controllers, who possessed enlarged craniums, had the position of highest possible authority. (TV: 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. (TV: Earthshock)
Early history Edit
Cybermen were originally a wholly organic species of humanoids who arose on Earth's former twin planet, Mondas. Mondas drifted into the outer solar system to become an orphan planet. The Mondasians adapted by turning themselves into cyborgs. (TV: The Tenth Planet) Eventually all of the Mondasians underwent forced cyber-conversion. (AUDIO: Spare Parts) According to another account, they evolved from the Voord and Mondas was once the planet Marinus. (COMIC: The World Shapers)
- See Creation of the Cybermen for more details.
The original Mondasians retained more of their organic form. They had personal names. Another group, the Faction, left Mondas and headed for Planet 14. These developed into groups without connection to one another. (PROSE: Iceberg)
Mondas developed a drive propulsion system. This was placed in the planet's core to move the entire world. As the original Cybermen were limited in numbers and were continually being depleted, they decided to invade Earth. (TV: The Tenth Planet)
Scout crafts were sent to find her 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 Eighth Doctor made sure that all Cyber-Technology from the expedition was destroyed. (AUDIO: The Silver Turk)
Middle history Edit
20th century Edit
The Seventh Doctor and Ace fought Cybermen in London in 1940. (PROSE: Illegal Alien) They would later fight them in Nevada in 1954. These Cybermen were from Mondas, trying to invade. Their attack was delayed until 1986. (COMIC: The Good Soldier)
By 1970, Cybermen, specifically the Faction led by a Cyber-Planner (PROSE: Iceberg), had 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. (TV: The Invasion)
From the mid 1970s through 1985, Cybermen lurked in the sewers below London, awaiting another invasion. (TV: Attack of the Cybermen) This would happen in December 1986. (TV: The Tenth Planet) One of these Cybermen attempted to convert the staff and patients of a hospital using Cyberworms. The Third Doctor and Jo Grant foiled this attack by reprogramming a Cyber rat to emit a signal which shut down cyber technology. (PROSE: The Piper)
In 1975, a Cyberman's head was found in the London sewers and stored in Henry van Statten's Vault, where he held alien artefacts. (TV: Dalek) Another Cyberman head was also found that year in Deffry Vale station and stored in the Leamington Spa Lifeboat Museum. (GAME: Security Bot)
Having captured a time vessel, the Cybermen knew that the First Doctor would eventually destroy Mondas. They planned to divert Halley's Comet towards Earth in 1985. They hoped the destruction of Earth would change the past so Mondas would survive. The Sixth Doctor foiled them. (TV: Attack of the Cybermen)
In December 1986, 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 absorbed too much energy and was destroyed, as were the Cybermen on Earth who depended on Mondas for power. (TV: The Tenth Planet) Following the destruction of Mondas, the Cyberman would make Lonsis their new home. (AUDIO: Human Resources) One account also claims that the Cyberships were examined and exploited by humans, allowing them to make advances in space travel. Sarah Jane Smith described the invasion as "both the greatest disaster and most astonishing blessing ever to have happened to the human race." (PROSE: The Power of the Daleks)
The Cybermen and a group of mercenaries led by Karl made an alliance with the Daleks in a gambit to sabotage a peace conference on Earth in 1988 and have the planet destroyed. The Cybermen and the mercenaries had a much more active role than the Daleks, as they were tasked with kidnapping an American envoy on whom the success of the conference depended and in capturing the Doctor whom the Dalek Emperor declared a vital part of the plan. The Daleks took a more behind-the-scenes approach as they planned to use the mercenaries and Cybermen as nothing more than scapegoats who could be blamed for the destruction of Earth by the Galactic Council while the Dalek involvement remained a secret. When the Sixth Doctor revealed this information to the Cybermen and the mercenaries, they immediately turned on the Daleks. (AUDIO: The Ultimate Adventure)
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. (TV: Silver Nemesis)
21st century Edit
In 2005, (COMIC: Hunters of the Burning Stone) Cybermen from the future time travelled to Earth to announce themselves to the public. They hoped to flood Earth, using a powerful water-like nerve agent to make humans willingly participate in cyber-conversion. The Eighth Doctor, having absorbed a segment of the Time Vortex for a brief period of time, turned their entire army to dust, and decomposed their ship slowly, causing it to explode soon after. (COMIC: The Flood)
In 2006, Cybermen again invaded Earth's South Pole. (PROSE: Iceberg) In the same year, the Cybermen on Lonsis tried to invade Earth via the portal in the main branch of Hulbert Logistics.The Eighth Doctor and Lucie Miller destroyed them. They used a quantum crystalliser to make the Cybermen and their ship rapidly rust into dust. (AUDIO: Human Resources)
In 2008, several Cybermen and a Cyber-Planner who were allergic to gold attempted to gain time travel. They converted Byron, but their ship was destroyed by Charlotte Pollard (AUDIO: The Girl Who Never Was)
In the 2010s, a Cyberman was a resident of the hidden trap street in London which housed lost aliens on Earth under the protection of Mayor Me. As with the rest of the inhabitants it appeared cloaked in human form through use of the lurkworms. It was observed by the Twelfth Doctor and Clara Oswald as it had maintenance performed on it by an Ood. (TV: Face the Raven)
In 2021 a group of Cybermen claimed to want to become organic again. A space program used this to their advantage. However the Cyberleader lied, in fact having tricked the agency into creating a conversion chamber. The Seventh Doctor, Ace and Hex foiled this scheme. (AUDIO: The Harvest)
By 2070, the Cybermen were known and feared in several galaxies (PROSE: Doctor Who and the Cybermen) 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. (TV: The Moonbase)
In 2079, (AUDIO: Second Chances) Space Station W3 was the site of a takeover by the Faction, but were defeated by the Second Doctor. (TV: The Wheel in Space) In a second attack on the wheel, the Cybermen were sent into the Land of Fiction by Zoe Heriot. (AUDIO: Legend of the Cybermen)
Post-21st century Edit
The Cybermen had all but passed into legend when an archaeological expedition on the planet Telos found the Cyber-tombs. Hordes of Cybermen waited in cryogenic suspension. Earth's Brotherhood of Logicians intended to awaken them, believing the Cybermen would be receptive to their cause. The tomb would be sealed again (TV: The Tomb of the Cybermen) and later re-activated. (TV: Attack of the Cybermen)
- Main article: Cyber-Wars
During the Orion War of the early 26th century, humans tried to salvage Cyber-Technology from derelict ships to defeat the androids. This led to both sides nearly wiped out and the temporary conquest of Earth before the Cybermen resurgence was stopped. (AUDIO: Sword of Orion, AUDIO: Cyberman)
In 2526, several planets united to oppose the Cybermen in an event called the Cyber-Wars. A force of Cybermen tried to devastate Earth with a Cyberbomb and convert the survivors. Failing this, they hoped to crash the 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. (TV: Earthshock)
One of the last acts of the Cybermen in this war the attempt to blow up the planet Voga to stop the production of glitterguns. (PROSE: Revenge of the Cybermen) In the aftermath of their failure, the Cybermen were reduced to scattered remnants. One group relentlessly hounded the remaining fragment of Voga. (TV: Revenge of the Cybermen)
Later history Edit
On Telos, the Cybermen plotted to change history and divert Halley's Comet to Earth to destroy it and to save Mondas. (TV: Attack of the Cybermen) At some point, Telos was shattered by an asteroid impact. (AUDIO: Telos)
Telos was not the only site of Cyber-Tombs. There were dozens across the galaxy and more wars were started. Bernice Summerfield spoke of the Telos expedition and other tombs being discovered in the past tense. She was sent to one by Irving Braxiatel in the early 27th century. Braxiatel intended to use the Cybermen as a private army but was thwarted. (AUDIO: The Crystal of Cantus)
The remaining Cybermen from the Cyber-Wars ship finally caught up to Voga, now in orbit around Jupiter. Their attempt to destroy it would be defeated and their craft and themselves detroyed due to the involvement of the Fourth Doctor, Sarah Jane Smith, and Harry Sullivan. (TV: Revenge of the Cybermen)
By 3286, the Cybermen had been thought dead for centuries. A group of these Cybermen led by a Cyber-controller attempted to gain time travel. Around this time, Goddard arrived. Goddard was a super developed Cybermen,from an alternate 1930s where the human race had become cyborgs indistinguishable visually from humans thanks to a Cyber virus. The Cybermen manged to reverse-engineer the virus Goddard brought but were defeated by the Sixth Doctor. (WC: Real Time, AUDIO: Real Time)
Cybermen from the far future would use time travel to return in time to the 2000s to convert Earth. They used rain that caused extreme emotions (sadness, fear, anger) to convince the humans that emotions were bad and to accept conversion willingly. The reason they needed humans from a past era was clear to the Doctor; in the future of the Cybermen, the human genetic template had been corrupted and augmented by their interactions with many alien races. The Cyber-conversion protocols were keyed to human or Mondasian biology; the number of available converts would drop dramatically.
The Doctor offered to regenerate for them so they could gather the data of his regeneration and upgrade their conversion protocols to include other races, in exchange for leaving the Earth alone. The Cybermen agreed, but betrayed him at the last moment (the Doctor was expecting this). Using the fragment of the Time Vortex the future Cybership used as a power source, the Doctor destroyed the Cyberfleet and dissolved them into rain. (COMIC: The Flood)
The Cybermen were notable customers of the information regarding the Doctor held by the Inforarium. When the Eleventh Doctor discovered the Cybermen, as well as the Daleks and Sontarans, had been purchasing this information, he infiltrated the Inforarium and memory-proofed their database using methods he learned from the Silence. The information sold was thus instantly forgotten. (HOMEVID: The Inforarium) This led to the Cybermen losing data on the Doctor. (TV: Nightmare in Silver)
A thousand years after the destruction of the Tiberian spiral galaxy and the end of the Cyber-Wars, the Cybermen were thought to be extinct. Yet surviving Cybermen lay beneath the future site of Hedgewick's World of Wonders. When the theme park was built, the Cybermen began using Cybermites to kidnap people as "spare parts". Angie and Artie Maitland arrived on Hedgewick's World with the Eleventh Doctor and their nanny, Clara, and were taken by the Cybermen. With enough components to reawaken them, after being presumed extinct for a thousand years, the Cybermen awoke from their tombs.
The Cybermen began attacking Natty Longshoe's Comical Castle to convert the humans there, but the Doctor, in a battle for his mind with the Cyber-Planner, Mr Clever, had them stop in place to bring in the local resources to win the chess game. The Doctor used a hand pulse to redistribute Clever among the rest of the Cybermen. Angie and Artie were also released. Emperor Ludens Nimrod Kendrick Cord Longstaff XLI gave the verbal command to start the countdown of a planet-imploding bomb. This drew the attention of his ship, which transmatted the Doctor and the humans on the planet while the Cybermen were left behind. The planet and the Cybermen were destroyed; however, one Cybermite survived the destruction. (TV: Nightmare in Silver)
Final evolution Edit
The Cybermen would ultimately transcend into pure energy. They would redeem the whole of sentient life and become the most peace loving-species in the whole of creation, purely thought with no physical presence. (COMIC: The World Shapers)
Rassilonian Era Edit
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 mostly destroyed by a similarly transported Raston Warrior Robot. The survivors allied with the Master, but he betrayed and destroyed them. (TV: The Five Doctors)
During the Doctor's era, the Cybermen allied themselves with the Master to become the rulers of Gallifrey. After they kidnapped Susan Foreman, they were stopped by the Fifth Doctor. (PROSE: Birth of a Renegade)
Undated events Edit
The Cybermen were involved in the Siege of Trenzalore. After being summoned to Trenzalore by the First Question, the Cybermen attempted to pass through the Papal Mainframe's force field. One attempt involved a Wooden Cyberman as it was low-tech and would not trigger any alarm system but the Doctor tricked the Cyberman into destroying itself. Later, the Daleks attacked the Mainframe and learned how to break the force field. The Cybermen followed them and fought the Doctor and the Silents until all the Cybermen, like many other species involved in the battle, were either killed or saw fit to retreat. (TV: The Time of the Doctor)
A Cyber Ship was chased by a Dalek flying saucer. Inside the ship, two Cybermen interrogated a Dalek Lumpy about the whereabouts of the Orb of Fates before be flattened by the Doctor's TARDIS. The Twelfth Doctor sent Lumpy on Telos to retrieve a second element of the Orb. (GAME: The Doctor and the Dalek)
Alternate timeline Edit
It is impossible to tell, as the temporal discrepancy featured has never been resolved, but Real Time may involve a divergent timeline.
In an alternate timeline created by the Black Guardian, the First Doctor never left Gallifrey. He became Lord President. The Cybermen were one of many aliens which invaded Earth, and fought over the planet with other races. This timeline was destroyed when the Seventh Doctor retrieved the Key to Time. (COMIC: Time & Time Again)
In another alternate timeline in which a successful WOTAN paved the way for World War III, the Cybermen successfully occupied the Arctic in their 1986 invasion. They came to agreements with the South African forces fighting the British, supplying them with technology and weapons that gave the former a huge advantage in the war, particularly in the South African invasion of Britain. The First Doctor averted this timeline by halting the world on its road to war in 1972, (PROSE: The Time Travellers) and later averted its causes altogether by defeating WOTAN in 1966. (TV: The War Machines)
If the Eleventh Doctor and Jean-Luc Picard did not defeat the Cybermen and the Borg, the Cybermen would eventually defeat the Borg, and invade both the Doctor's universe and the Federation universe, with planets invaded incluing; Raxacoricofallapatorius, Qo'noS, the Judoon homeworld, and finally Starfleet Academy in San Francisco. (COMIC: Assimilation²)
Parallel universe Edit
In the Federation universe, the Cybermen invaded an Archaeological site on Aprilia III and began to convert the people onboard into Cybermen. They encountered the Fourth Doctor, Captain James T. Kirk, Spock, McCoy and Scotty. The Fourth Doctor stopped them by using the gold on Kirk's communicator to clog the Cybermen's respiration. (COMIC: Assimilation²)
The Cybermen entered into an alliance with another cybernetic species, the Borg, from a Federation due to their identical goals of assimilating other species. On Stardate 45635.2 in 2368, a joint Borg/Cyberman assault force attacked the Federation planet Delta IV and quickly overran it. This attack made the Cybermen known to the Federation. (COMIC: Assimilation²)
Other references Edit
Mysteries and discrepancies Edit
On Telos, the Second Doctor seemed to have knowledge, if not foreknowledge, of the Cyber-Tombs. (TV: The Tomb of the Cybermen) The Cyber-Planner's reference to having met the Doctor on Planet 14 also remains obscure, (TV: The Invasion) though one account tries to explain this in a way which contradicts previously disclosed information about the creation of the Cybermen. (COMIC: The World Shapers) By the time the Cybermen invaded Space Station W3, the Second Doctor was "known and recorded as an enemy of the Cybermen". (TV: The Wheel in Space)
Behind the scenes Edit
Inspiration for the Cybermen Edit
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.
Prologues to certain Target Books novelisations reflect the earlier ideas about the Cybermen and state they perfected the science of cybernetics to gain immortality. The Cybermen were the result: immortal, but at the price of loss of their humanity.
Development of the characters Edit
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 the comic strips in The Flood and one more in Nightmare in Silver. Minor re-designs would take place as well. As the Cybermen stories do not appear in a chronological order, this makes their evolution rather confusing; more 'advanced' Cybermen are around at the same time as more 'primitive' ones. This can be explained by time travel, though the Cybermen only captured one time ship. (TV: Attack of the Cybermen)
The Brilliant Books Edit
- According to The Brilliant Book 2011, at Blenheim Palace, the Fourth Doctor was hunting Cybermats, suggesting Cybermen activity.
- According to The Brilliant Book 2012, at one point, Vastra and Jenny battled the Cybermen.
The non-narrative source Doctor Who: Cybermen, by David Banks, went into further detail about Cybermen and Cyberman factions. Banks created a number of terms — CyberFaction, CyberNomad, CyberTelosian, CyberMondasian, and others — to explain the differences in the Cybermen's costumes on television. Some of the terms, in adapted forms, appear in his later novel, PROSE: Iceberg. It is these forms — Mondan and the Faction, which this wiki prefers, according to our canon policy.
The history Banks presented as "non-fiction" was largely ignored by other authors and so can't be considered in the writing of most of our articles. Here are some of the points that Banks made which never made it beyond Doctor Who: Cybermen:
- The departure of the CyberFaction (that is, the Faction) from Mondas was thought to have occurred around 5000 BC in what Banks called the "First Divergence".
- In the "Second Divergence", a group which author David Banks called "CyberNomads" diverged from the Faction. These so-called "Nomads" searched for the validium statue Nemesis and tried and failed to destroy Voga.
- Possibly after the 21st century, the Faction abandoned their home in the Sol system and journeyed into the galaxy to colonise a suitable planet. The Cybermen which colonised Telos, possibly in 2175, split from the Faction and were called the CyberTelosians. This group united with the CyberNomads after they discovered the frozen CyberTelosians, and became CyberNeomorphs. These Cybermen planned to use Halley's Comet against Earth and were taken to the Death Zone on Gallifrey.
In other words, what Banks was trying to do was create terms for each of the different costumes he and his fellow performers had worn throughout the years. In effect he was saying that the costumes in Attack of the Cybermen were of CyberNeomorphs, the ones worn in The Tomb of the Cybermen were of CyberTelosians, and so forth.
The idea has not been widely ignored by other works. Even he did not in his book, Iceberg, which mentioned none of his terms precisely. It did not reference the CyberNeomorphs and CyberTelosians, and called the CyberFaction, "the Faction", and CyberMondasians, "Mondans".
