Cyberon War

You may be looking for the Cyber-Wars fought against the Cybermen.

The Cyber-War, also called the Cyberon War, was the protracted conflict between the Cyberons and the Earth Alliance.

It had been waging for almost a century by 2777, with Earth occupied partway through: during this, the Earth Alliance rebranded as the Tellurian Alliance. By the 2770s, it was standard for civilian casualties to be counted as Cyberon casualties if those humans were cybernetically augmented. (PROSE: Cyber-Hunt)

The war still raged in 3009. Once, while aboard a Cyberon vessel, Captain Harcourt Ross noted that one of the reasons the Cyber-War was taking long to win was because the Cyberons could convert both living and dead organisms. (PROSE: Flight of the Cyberons)

A few centuries later, the war was won by humanity and sarcastically called an expensive Cyberon (drug)"war on drugs"]] by one time-traveller. (PROSE: Barnyard of the Cyberons)

Behind the scenes

The Cyber-War against the Cyberons first appeared in the Audio Adventures in Time & Space story Cyber-Hunt, in which a mysterious "Fred" (implicitly an amnesiac version of Nicholas Briggs' Doctor) allies with a team of human soldiers on Carson's Planet and discovers a secret Cyberon facility developing nanite conversion methods, which the Wanderer tampers with so that the nanites attack Cyberons. Cyber-Hunt was adapted from an unproduced BBV Productions film called Cyber-War, which was at one point an adaptation of Sword of Orion and at another point was planned to feature Cybermen and Ice Warriors in conflict. (REF: Downtime – The Lost Years of Doctor Who) It was later novelised under the same name by Callum Phillpott; this new version of the narrative is the only one covered by this Wiki, as it introduced DWU elements into the plot, such as Aurichall. Nevertheless, it postdated Flight of the Cyberons, which thus stands as the first use of the Cyberon War in a valid DWU story.
