The Cybermen are a race of cyborgs from Doctor Who, serving as one of the series' most recurring and dangerous antagonists, rivalling the Daleks in that regard. The Cybermen are created out of humans, or humaniod species, who need to survive no matter what, whether to preserve their dying species, a bid for immortality, or an attempt to improve all those around them. Various factions of Cybermen have orginated independently due to parallel evolution, but are essentially the same in core.
All Cybermen are essentially living brains inside a robot body that robs them of emotion and free will. They are programmed to see themselves as a perfect life-form and work to "upgrade" others into more Cybermen, by force if needed. Any life-forms that resist or are incompatible with Cyber technology are to be "deleted".
Cybermen from Mondas
The first Cybermen were originally the people of the planet Mondas, the Tenth Planet of Earth's solar system, who converted themselves to survive when their world was knocked out of solar orbit and drifted into the deep space.
Having installed a drive propulsion system so they could pilot the planet itself, the Cybermen began conquering planets to convert the native life forms into more Cybermen to increase their numbers.
Mondasian Colony Ship
On an enormous Mondasian Colony Ship, which was trapped in the gravitational field of a black hole, the Cybermen rose once again. This was due to time dilation caused from the black hole, which led to 20 crew members, who traveled to the back of the ship to fix the engines, to experience time much faster than the front of the same ship. This led to minutes matching years at the two ends. Within two days/thousands, the crew was long gone and their descendants had built an enormous city. Due to pollution, lack of resources, and a brutal regime by the The Master, chances of survival were getting slim and a group of doctors decided to convert the population. It appeared that the Master (now in disguise after being overthrown by the people) was also the key architect in this plan. The converted would eventually become the Cybermen, who would later convert Bill Potts to lethally injure the Twelfth Doctor. The Twelfth Doctor managed to destroy most of the Cybermen in the end, but it appeared that at least some survived.
Invasions of Earth
The Cybermens' chronological first meeting with the Doctor was in 1970 when a group of Cybermen from "Planet 14" use industrialist Tobias Vaughn to pave the way for a ground invasion. However, the Cybermen are forced to retreat due to interference from Doctor with the aid of the newly formed United Nations Intelligence Taskforce. An advance force of Cybermen set up base in an Antarctic space tracking station in the year 1986 to summon Mondas. However, Mondas overloaded from draining Earth's energy for the Cybermen's use and ceased to be along with many of the Cybermen. But the Cybermen lingered on as species and confronted the Doctor in several time periods, with him thwarting them.
Mondas arrived in Earth's solar system in 1986, in The Tenth Planet, and began draining Earth of it's energy. The First Doctor met an advance force of Mondasian Cybermen near Snowcap Base in Antarctica. This force was to use the experimental Z-Bomb to destroy Earth before Mondas absorbed too much energy. Due to the efforts of the Doctor and his companions, Mondas absorbed too much energy and was destroyed, as were the Cybermen on Earth who depended on Mondas for power.
Ending up in a parallel universe with his companion Rose Tyler and her boyfriend Mickey Smith, the Tenth Doctor finds the parallel Earth to be the genesis of that reality's Cybermen. The product of a dying transhumanist named John Lumic, founder and owner of the multinational company Cybus Industries, these Cybermen were created from the homeless and acted on his will to convert every human into a Cyberman. However, the Doctor and his friends stop the Cybermen by deactivating the emotional inhibitors that keep the Cybermen from going insane. Afterwards, a resistance group, the Preachers, set about to clean up the remainder of Lumic's factories around the world.
Thanks to the Cult of Skaro, the Cybus Cybermen exploited a breach between universes found by Yvonne Hartman to invade London under command of their Cyberleaders. Though the Doctor manages to send the parallel Cybermen into the void, traces of their actions in Canary Wharf remain such as a partially converted Torchwood employee named Lisa Hallett who was killed months later by her follow Torchwood operatives.
However, due to the actions of the New Dalek Empire, the parallel Cybermen escaped the void and ended up in London 1851, where they enlisted the aid of a human named Mercy Hartigan before they are destroyed for good by the Doctor by sending their giant robot, the "Cyber-King" into the time vortex.
In Dark Water/Death in Heaven, a group of Cybermen allied with the Master, who developed a way to convert the deceased into Cybermen. They also gained the ability to fly via rockets built into them. Once a large enough army was raised they invaded London once again. However, when the Twelfth Doctor took the control bracelet from the Master (which controlled all the Cybermen), he gave it to a converted Danny Pink who lead all the Cybermen up into the sky where they all simultaneously self destructed.
Later attacks on Earth
By 2070, humanity presumed the Cybermen were wiped out. However, in The Moonbase, the Cybermen subtly invaded the Earth's Moonbase, which could control the weather with the Gravitron, poisoning the crewmembers, and taking over others. They planned to use the Gravitron to destroy humanity. They were defeated by the Second Doctor, and his companions Polly, Ben and Jamie, who fought off the Cybermen in the base, and being thrown into space via altering the Moon's gravity.
In The Wheel In Space, a faction of Cybermen attacked the Space Station W3, also known as The Wheel, as part of a plan to use its direct radio link with Earth as a beacon for their invasion fleet. They infiltrated the the station with the aid of the Cybermats, but the Doctor, who was "known and recorded", thwarted them with the aid of the crew.
A Cyberman was once among the many creatures that Vorg had in his miniscope in Carnival of Monsters.
The faction the Cybermen that attacked the Moonbase belonged to would later colonise the planet Telos for it's access to cryogenic facilities, defeating the native Cryons, who would form a resistance. The Cybermen would go onto freeze themselves in gigantic "tombs" to preserve themselves.
In the 25th century, the Cybermen had all but passed into legend. The Brotherhood of Logicians scoured the universe for Cybermen, believing that they would be receptive to the Brotherhood's cause. In The Tomb of the Cybermen, the Brotherhood of Logicians financed Parry's expedition to find the cyber-tombs on Telos. With the help of the Second Doctor, Jamie, and Victoria Waterfield the expedition found and opened the cyber-tomb. After the hibernating Cybermen were reawakened, Klieg and Kaftan, the secret representatives of the Brotherhood attempted a negotiation, which inevitably. Realising the true danger of the Cybermen the expeditions quickly resealed the tombs.
In the year 2526, in Earthshock, a force of Cybermen attempted to destroy Earth to prevent a peace conference that could unite the enemies of the Cybermen. The initial plan was to use a Cyber-bomb, guarded by androids. However, after an archaeological team was mostly killed, a military force ended up uncovering the plot, and the Fifth Doctor managed to disable the bomb. As a back up plan, the Cyber-Leader elected to crash a human freighter into the Earth. However, due to the interference of Adric, the freighter instead jumped back through time, to crash into Earth 65 million years ago, as part of it's history.
After the war, in Revenge of the Cybermen, several Cybermen and a few Cybermats survived and tried to destroy the gold planet of Voga. Their attempt to destroy it was defeated and their craft and themselves deatroyed due to the involvement of the Fourth Doctor, Sarah Jane Smith, and Harry Sullivan.
After a timeship landed on Telos, in Attack of the Cybermen, the Cybermen 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.
After their time travel scheme was thwarted, a Cyber-Fleet remained stranded in the 20th century. In Silver Nemesis, during November 1988, a scouting party was sent to Earth in search of a statue made of validium called Nemesis, a Time Lord weapon, planning to use to transform Earth into the new Mondas. The Cybermen met Lady Peinforte, who brought many of their number down with gold-tipped arrows. They allied with Neo-Nazi De Flores, but both inevitably betrayed each other. The Leader apparently forced the Seventh Doctor to surrender the Nemesis. Their force was destroyed by Nemesis as the Doctor had instructed.
At Stonehenge the Eleventh Doctor and Amy Pond encountered Cybermen whose exact origin was never explained, although resembling John Lumic's Cybermen. They had teamed up with others of the Doctors enemies like the Daleks, the Judoon and the Sontarans to save the universe by trapping the Doctor in the Pandorica. However, they vanished from existance when the TARDIS exploded.
Others of these Cybermen, called the Twelfth Cyber Legion, were visited by the Eleventh Doctor and Rory Williams, when they were searching for Amy Pond, who was imprisoned by Madame Kovarian. Their Cyberleader told Rory her location after the Doctor destroyed some of their spaceships.
After one of their ships later crashed on Earth in Colchester, they fought the Doctor one more time, when he visited Craig Owens. Like the Cybermen from Mondas, they used Cybermats. They tried to convert Craig into their new Cyber-Controller, but his feelings for his infant son were so strong, that he was able to override to process and blow up their ship.
Post Cyber-WarsThought to have been extinct for centuries, using advanced minuscule Cybermats known as Cybermites to spy and gather parts for them, Cybermen underwent massive upgrades to make them invincible to the point that only a planetary destruction device can be used against a single Cyberman if not dealt with quickly. These enhancements include Cyber-conversion by Cybermites, detaching their limbs, super-fast speed, and the ability to convert non-humanoid life forms as the Eleventh Doctor found out. The Doctor got briefly possessed by their Cyber Planner who called itself Mr. Clever. However the Doctor temporarily immobilised them which gives enough time for him, Clara, and other human troops to evacuate and destroy the planet they are on.
This model was also present in the siege of Trenzalore, devising one with a wooden exoskeleton armed with a flame thrower to avoid detection. The Eleventh Doctor is able to trick and destroy it by using it's own weapon against it.
The Last of the Cybermen
At the end of the universe, a group of Cybermen living within an asteroid were found by Rassilon after he was banished from Gallifrey. Rassilon saw the potential in allying with the Cybermen and let himself be converted into a Cyber-Leader. With Rassilon's assistance, the Cybermen attacked and conquered Gallifrey, and rewrote history with the Time Lords' technology to keep the Doctor occupied.
In the new timeline, Cyber-Silurians seeded the universe with ark ships containing cyber-technology. The 11th Doctor attempted to stop the launch of the arks, but he was captured and assimilated. After the CyberKings captured the Sontaran cloning worlds and caused the extinction of the Rutan Host, the 10th Doctor was unable to stop an ark from converting Sontar on a planetary scale. The Sontaran cloning factories were then altered by the Cybermen so that they produced an endless supply of Mondasians to convert. Earth was completely taken over by Cybermen in 2006. After Rose Tyler was converted and Jack Harkness was killed, the 9th Doctor tried to destroy the Cybermen. Instead, he was infected with nanobots and cyber-converted.
At the end of the universe, the Cybermen used looms to siphon the regenerative energy from Time Lords into the Eye of Harmony. They planned to use the Eye of Harmony to shape formation of the next universe, making a reality perfectly suited to the Cyberiad. The Twelfth Doctor came to Gallifrey and confronted Rassilon and the Cybermen. When the Doctor was forced into a loom, the Cyber-Controller betrayed Rassilon and put him in a loom as well. The Doctor and Rassilon used their combined willpower to influence the energy being pumped into the Eye of Harmony and instead of regenerating the future, they regenerated the past. Everything the Cybermen had done was reversed and their supremacy over all of time and space was wiped from the memory of the universe.
