Cyber-Force

The Cyber-Force, also known as the Cyber-Empire, (COMIC: The Bidding War) or Cyberman Empire, (PROSE: Doctor Who and the Cybermen) referred to the collected forces of a Cyberman army. Jack Harkness described it as an "empire of evil". (TV: Fugitive of the Judoon)

History

In 1988, a Cyber-Force arrived with of fleet of thousands of warships, planning to take possession of the Nemesis statue and turn Earth into their new base planet, the "New Mondas." This force seemed more leery of exposure to gold, with the Cyber-Lieutenant questioning the Cyber-Leader that should they fail the Cyber-Force would cease to exist, with the Leader commenting that he was operating outside his function. The Seventh Doctor tricked the Cybermen by using the Nemesis to destroy the entire Cyber-Fleet. (TV: Silver Nemesis)

In 1992, a Cyber-Force composed of a Cyber-Fleet of at least twenty Cyber-Warships with at least two hundred thousand Cybermen attempted to conquer Earth by dehydration, but the Sixth Doctor programmed their weapons to target the methanol that served as the "lifeblood" of cyber-technology.

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)

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

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.
