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.
