New Mondas

New Mondas was an adopted home of the Cybermen, named after their original homeworld Mondas.

A Cyber-Fleet, possibly having time travelled, attempted to use the Nemesis to convert 1988 Earth into the New Mondas, but was subsequently destroyed by the Nemesis on the Seventh Doctor's instructions. (TV: Silver Nemesis)

More advanced Cybermen from the future attempted again in 2005 to turn Earth into New Mondas as a way of "saving" humanity from itself, before the Eighth Doctor ustilised their section of the Time Vortex to destroy them. (COMIC: The Flood)

A New Mondas was eventually established but, along with Telos, was destroyed by 3985, (PROSE: Legacy, Theatre of War) at the hand of the Daleks, who detonated Oblivion Continuums they had installed in newly converted Cybermen from the Seventh Cyber-Fleet. The initial explosions wiped out the planet's capital city of Cyber-Command, the Cyber-Controller, a Cyber-Leader, and any other Cybermen within the city. Watching the destruction from a safe distance, a Dalek proclaimed this victory marked the fall of Cyber-Empire, which would hence forth "[belong] to the Daleks". (COMIC: Cyber Crisis)
