Cyber-Wars

The Cyber-Wars were a series of galactic conflicts in which an alliance made a concerted effort to wipe out the Cybermen.

The First Cyber Wars and the Vogan war
By the 2150s, a group of Cybermen known as the CyberNomads were involved in the Vogan War. (PROSE: Killing Ground)

In the late 22nd century, a series of conflicts known at the time as "the Cyber-Skirmishes" occurred between humans and Cybermen at the outermost human colony planets. (PROSE: The Janus Conjunction)

There were also reference made to "Cyber-Wars" occurring by the mid-23rd century, having left Earth financially destroyed in combination with the 22nd century Dalek invasion. (PROSE: Theatre of War) One account held that the first Cyber-War began in the 2260s, when human colony worlds like Burnt Salt had their populations ravaged by mass conversions. (AUDIO: The Tyrants of Logic)

Another reference was made to Cyberwars in the early 24th century, (PROSE: The Dimension Riders) followed by a period of peaceful expansion until colonial incidents in 2387. (PROSE: Infinite Requiem)

The Great Cyber War
The most well known of the Cyber-Wars was the one where the glittergun was developed. (TV: Revenge of the Cybermen) It was known as "the Cyberwar", (TV: Revenge of the Cybermen, PROSE: The Revenge of the Cybermen) the "Second Cyberwar", (PROSE: Original Sin) or the Great Cyber War. (AUDIO: Last of the Cybermen, TV: The Timeless Children) Gold was a major weakness of the Cybermen. The glittergun could fire gold dust at them. According to the Fourth Doctor, humans discovered that weakness and invented the gun as a result of that discovery. This invention was the end of Cybermen, which disappeared after their attack on Voga at the end of war. According to a Cyber-Leader, if humans had not had the resources of Voga, the Cybermen would have won the war. (TV: Revenge of the Cybermen) According to, he bore witness to the war and the "atrocities" done to the Cybermen in it. (TV: The Timeless Children)

The war resulted in the near-complete destruction of the Cyber race. Earth forces launched a final assault on Telos, during which the planet's surface was bombarded. Remnant groups of Cybermen fled across the galaxy. These surviving Cybermen learned from the war that humans would always resist them and so they thought it better to destroy them rather than to conquer them. The Sixth Doctor estimated that, with the destruction of the Super Controller, these remnants would be less stable and more prone to emotions, such as revenge. (AUDIO: Last of the Cybermen)

A large Cyberman fleet escaped the bombardment of Telos and fled to a dwarf planet in the Kuiper Belt. They waited 10 years after the war's conclusion, intending to travel back to the time of the bombardment, defeat the enemy and then launch an attack on Earth, changing the outcome of the conflict in their favour. However, Zoe Heriot and then Findel, managed to take over the mind of the Super Controller. They were able to control the Cyberfleet and had the thousands of ships crash into the planet. This completed the bombardment and destroyed the foundations of the Cyber Empire, ending the war. (AUDIO: Last of the Cybermen)

One remnant group attempted to retaliate by destroying Voga, the planet of gold, but were destroyed when the Fourth Doctor instructed the Vogans to fire their rocket Skystriker at the Cyber-ship. (TV: Revenge of the Cybermen)

26th century: The Orion War and an alliance against the Cybermen
By 2503, the Cyber Wars were long over and the Cybermen were in stasis in their Tombs on Telos. (AUDIO: Sword of Orion)

Telos was destroyed by a suspected asteroid impact between five and ten years before their part in the Orion War between the Humans and the Androids in the 26th century. (AUDIO: Telos) By 3286, the earlier Orion War was viewed as part of the Cyber-Wars by Reece Goddard. (WC: Real Time, AUDIO: Real Time)

In 2526, the general population had no knowledge of Cybermen, although various governments intended to sign a pact to unite against the Cyber-race. A force of Cybermen attempted to prevent the war. They tried to destroy the Earth, first with a Cyber-bomb and then by crashing a human-freighter into the Earth to prevent the alliance who planned to fight them from forming, destroying the unity. In the words of the Cyber-Leader, it would have been a great psychological victory that was designed to destroy the general morale. Indeed, the Cybermen of this period regularly performed scientific study of human emotion. Both attempts to destroy the Earth were stopped by the Fifth Doctor, who claimed that the Cybermen could not possibly win the coming war. (TV: Earthshock) This event was recorded under Onslaught on Earth, one of the Cyber-Documents. (AUDIO: The Ultimate Cybermen) Having failed to destroy Earth while losing their Cyber-Leader, (TV: Earthshock) the Cyber-Fleet dispersed. (TV: Time-Flight)

What happened to the fleet afterwards remained a mystery to the CyberHive, an attempt at chronicling the history of the Cybermen from the Cyber-Documents. ArcHivist Hegelia suggested that an agreement was reached to join forces against the Cybermen, resulting in a Cyber-War beginning in the solar system with a battle between the main Cyber-Fleet and human forces which extended to other parts of the galaxy before the Cybermen were ultimately overcome. (AUDIO: The Ultimate Cybermen) Spacefleet, which came into being during the Cyber-Wars, was used to combat the Daleks in the Second Dalek War which began later in the 26th century. (PROSE: Deceit)

By the 40th century, the Cybermen were declared extinct. At some point before this, they colonised another planet, which they named New Mondas but both New Mondas and Telos had since been destroyed. (PROSE: Legacy, AUDIO: Telos)

War in the Tiberian Galaxy and aftermath
Around the 52nd century, the Cyber Legions were a powerful force in the universe. (TV: A Good Man Goes to War, PROSE: The Heist) The Legions, which were connected to the Cyberiad, had some activity in the Tiberian spiral galaxy. (PROSE: Ghost in the Machine) The Tiberian spiral was a significant location in the Cyber-Wars between humanity and the Cyberiad. These Cyber-Wars had the Cybermen constantly upgrading themselves to overcome any weaknesses that could be exploited. The Tiberian spiral galaxy was sacrificed to destroy all of the Cybermen with a bomb when nothing else appeared to work.

Because of the damage done to one of the planets the war was fought on, Hedgewick bought it cheap and set up his own amusement park there; it was said to be the best ever in all of history. However, unknown to all, the planet had become home to three million damaged Cybermen transported there by a Valkyrie during the war. Patrons from Hedgewick's World of Wonders began to be kidnapped to supply spare parts to fix the damaged Cybermen.

Some of the deactivated Cybersuits also ended up in Webley's collection. However, they had similar appearances to the variety of Cybermen created by Cybus Industries and those of the Cyber Legions. (TV: Nightmare in Silver)

Re-emergence
A thousand years after the end of the war in the Tiberian galaxy, the Cybermen were considered extinct once again. However, the very existence of a single Cyberman was such a threat that it had become procedure to blow up any planet where one was discovered. Shortly after the Eleventh Doctor arrived on Hedgewick's World of Wonders with Clara Oswald, Angie Maitland and her brother Artie, the three million Cybermen on the planet began to revive, planning to use the Doctor as their new Cyber-Planner. At the end of the battle, Emperor Ludens Nimrod Kendrick Cord Longstaff XLI set off a bomb to destroy the planet, killing every Cyberman there before they could escape. However, a single Cybermite survived unnoticed. (TV: Nightmare in Silver)

In 6048, Cole of the human mining world Heritage mentioned that his grandmother fought in the most recent Cyberwar. (PROSE: Heritage)

In the far future
At a point in the far future where exact measurements of time were no longer meaningful, the Cybermen were utterly destroyed in a great war with the universe. (WC: Real Time, AUDIO: Real Time) All Cyber-Fleets were destroyed by a force led by the Doctor. (AUDIO: The Reaping) Only a handful of Cybermen survived, but they were tracked down by bounty hunters and mercenaries. One Cyber-Controller, who was the Sixth Doctor's former companion Evelyn Smythe, hid on Chronos and discovered a time portal leading to 3286, which he used to create the Cyberverse. (WC: Real Time) Another survivor, a Cyber-Leader, discovered an abandoned TARDIS on "a planet ruined by fire", travelled back to 1980s Earth and set a different trap for the Sixth Doctor. (AUDIO: The Reaping)

In the far future there existed "fake Cyberdudes" who did reenactments of battles from the "last great Cyberwar". Gabby Gonzalez, the Tenth Doctor, Cindy Wu, and Anubis once encountered these reenactors. (COMIC: Vortex Butterflies)

In what the Thirteenth Doctor described as the "very far future", the Cyber-Wars were fought over a period of some decades, and ultimately ended with the near-annihilation of both humanity and the Cyberman, and thus the fall of the Cyber-Empire. (TV: Ascension of the Cybermen) The Alliance, which opposed the Cybermen, acquired the Cyberium, an artificial intelligence containing the knowledge and history of the entire Cyber-race, and sent it back through time across space. (TV: The Haunting of Villa Diodati, The Timeless Children) Knowing that it was being pursued by the Lone Cyberman, Captain Jack Harkness attempted to make contact with the Thirteenth Doctor in 2020, using her companions to pass on a warning to not give the Lone Cyberman what it wanted. (TV: Fugitive of the Judoon, The Haunting of Villa Diodati)

Aftermath
Following the fall of the Cyber-Army, a human named Ashad partially converted himself and became the Lone Cyberman, intent on reigniting the fallen empire. (TV: The Haunting of Villa Diodati)

Via time hop, Ashad travelled back in time to 1816 to attempt to extract the Cyberium, which had entered the body of Percy Shelley. The Thirteenth Doctor absorbed it herself, knowing Shelley's death would alter the future. However when Ashad threatened to tear reality by summoning his ship, she relinquished the Cyberium to him, knowingly ignoring Jack's warning but deciding she would rather confront the Cybermen in the future than change the course of history by having the Earth destroyed in 1816. After taking the Cyberium, Ashad returned to his own time. (TV: The Haunting of Villa Diodati)

Years after the brutal Cyber-Wars ended, only seven known human survivors remained in the galaxy, hiding on a wasteland planet while they worked to repair their Gravraft. At least one other human, Ko Sharmus, remained on the planet of the Boundary, the galaxy's last safe place, where he held up camp on the chance that any more human survivors might find their way. The Boundary acted as a gateway to another point in the universe through which other survivors of the war had fled a long time before. (TV: Ascension of the Cybermen)

Using a Cybercarrier retrieved from one of the site of the Cybermen's greatest defeat, a ship which carried hundreds of thousands of Cyber-Warriors, ready to be awakened, (TV: Ascension of the Cybermen) Ashad attempted to bring about a new Cyber-Empire. His initial plan was to effect a "final ascension" for the Cybermen, into robots, before destroying all organic life with the death particle. Allying himself with, he landed his carrier on Gallifrey. However, the Master betrayed and killed Ashad in order to gain the Cyberium for himself. In the wake of the Master's plot to create and unleash a new race of CyberMasters, the Doctor's companions and the human survivors of the war destroyed the Cybercarrier and the Cyber-Army aboard it, foiling Ashad's plot. Ko Sharmus subsequently sacrificed himself to use the death particle to stop the Master and his army of CyberMasters. (TV: The Timeless Children)
