Cyber-Empire

The Cyber-Empire, (COMIC: The Bidding War, AUDIO: Last of the Cybermen) also known as the Cyber Empire, (COMIC: The Cyber Empire) or Cyberman Empire, (PROSE: Doctor Who and the Cybermen. COMIC: Deathworld) was, in the words of Jack Harkness, an "empire of evil" made up of Cybermen. (TV: Fugitive of the Judoon) At its height, the Cyber Empire was the most powerful force in the universe. (COMIC: The Cyber Empire)

History
The Second Doctor, John and Gillian encountered the Cyber Empire when it was led by a caped Cyber-Controller. By the Controller's demand, CyberMondans in Cyber-Hover-Craft kidnapped thousands of Earthmen to build a CyberCity in the Controller's honour. (COMIC: The Cyber Empire)

In December 1986, the CyberMondans' invasion of Earth resulted in the destruction of Mondas. (TV: The Tenth Planet) On 15 October 2070, Cybermen from Telos attempted to destroy the Earth in order to eliminate humanity, whom they saw as a potential threat to the Cyberman Empire, as thus gaining retribution for the destruction of Mondas. However, this attack was thwarted by the Second Doctor. (PROSE: Doctor Who and the Cybermen, TV: The Moonbase)

To the Ninth Doctor's recollection, the Cyber-Empire annexed Malleon in the early 54th century, in either the 5300s or 5310s. (COMIC: The Bidding War)

had an outstanding death warrant in the Cyber-Empire. (AUDIO: The Bekdel Test)

Ice Warriors once encountered Cybermen of the Cyberman Empire on Yama-10. (COMIC: Deathworld)

The Cyber-Empire also operated on New Mondas, where they were defeated by the Daleks. (COMIC: Cyber Crisis)

The Cybermen of Telos were part of the Cyber-Empire during the Great Cyber War. At the time of the Cybermen's defeat, the Super Controller was linked to every piece of technology in the Cyber-Empire. (AUDIO: Last of the Cybermen)

As observed by Captain Jack Harkness, the Cyber-Empire was ultimately brought to "ruins", having finally been "brought down to nothing". However, the risk of the Cybermen returning remained. In the 21st century, Jack told Graham O'Brien, Yasmin Khan and Ryan Sinclair that the Alliance sent something back through time and space to defeat the Cybermen as he gave the companions a warning for the Thirteenth Doctor regarding the Lone Cyberman.
