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.

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 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 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)
