Cyber - Wars The Cyber - Wars , also known as the Great Cyber Wars , ( AUDIO : " Last of the Cybermen " ) 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 CyberNomad s 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 " ) . 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 most well known of the Cyber - Wars was the Vogan War where the glittergun was developed . Gold was a major weakness of the Cybermen . The gun could fire gold dust at them . According to the Fourth Doctor , humans discovered that weakness and invented the gun , and that 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 " ) The wars resulted in 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 human s 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 Cyber fleet 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 " ) The 26th Century : The Orion War and the alliance against the Cybermen . By 2503 , the Cyber Wars were long ago and the Cybermen were tucked away 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 humanfreighter into the Earth to prevent the alliance who planned to fight them from forming . Both of these attempts were stopped by the Fifth Doctor . ( TV : " Earthshock " ) Spacefleet , which came into being during the Cyber - Wars , was used to combat the Dalek s in the Second Dalek War which began later in the 26th century . ( PROSE : " Deceit " ) The outcome of the 26th Century Conflict was presumably another major defeat . The Fifth Doctor described it as a war the Cybermen could not possibly win . ( TV : " Earthshock " ) By the 40th Century , the Cybermen were declared extinct . At some point before this they colonized another planet , which they named New Mondas but both New Mondas and Telos had since been destroyed . ( PROSE : " Legacy " , AUDIO : " Telos " ) Cyber Legions . Despite being brought to the edge of extinction by numerous conflicts , the Cybermen gradually recovered . As late as the 52nd century , fleet s such as the Twelfth Cyber Legion represented part of a major Cyber power in space . ( TV : " A Good Man Goes to War " ) The Tiberian Galaxy War . At the end of another war , the Cybermen began 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 . ( TV : " Nightmare in Silver " ) 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 . Hedgewick ' s World of Wonders . A thousand years after the end of the war in the Tiberian galaxy , the Cybermen were considered extinct again . However , the very existence of a single Cyberman was such a threat it was procedure to blow up any planet one was discovered on . 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 " ) Later conflicts . A later war , or wars , with the Cybermen were fought as some point in the far future . All Cyber - Fleet s were destroyed by a force led by the Doctor . A Cyber - Leader , obtaining Time Lord technology , travelled back to 1980 s Earth and set a trap for the Sixth Doctor .
