Deletion

Deletion was what the Cybermen of Pete's World termed the killing of all those they deemed incompatible for the upgrade to cyber-form. The primary instruments of deletion were the hands of the cyber-suits, which were capable of transmitting a fatal electric shock to humans, (TV: Rise of the Cybermen/The Age of Steel) and projectile weaponry such as cyber wrist blaster or energy blasters. (TV: Army of Ghosts/Doomsday) In N-Space, Cybermen of N-Space used eradication. (TV: Silver Nemesis)

Deletion was similar to the creed of extermination followed by the Daleks, who the Cybermen engaged during the Battle of Canary Wharf. (TV: Doomsday)

History

In Pete's World, the first known victim of deletion was Dr Kendrick, a scientist in the employ of John Lumic, CEO of Cybus Industries and inventor of the Cybermen, that oversaw the creation and testing of the prototype Cyberman in 2007. When Kendrick informed Lumic that Geneva needed to be informed of its creation Lumic gave his first Cyberman the order to kill him, which it promptly carried out. (TV: Rise of the Cybermen)
