3W Cyberman

Cyberdears was 's nickname (TV: Death in Heaven) for the army of Cybermen she had created with the 3W Institute. (TV: Dark Water)

Characteristics
This model of Cyber-body was identical to the "weapons-grade version" (TV: The Doctor Falls) which were notably associated with the Cyberiad following the Cyber Wars of the 250th Millennium, (TV: Nightmare in Silver) theorised by one source to be the result of cross-pollination between the Mondasian-descended Cybermen of the Doctor's universe and the Cybusmen of Pete's World. (PROSE: The Whoniverse) Incidentally, this model also advanced from Mondasian Cybermen in an instance of parallel evolution aboard a Mondasian colony ship in a genesis event overseen by Missy's previous incarnation,. (TV: The Doctor Falls)

History
Operating on Earth in the 2010s, oversaw the creation of a new Cyber-Army, (TV: Dark Water) whom she personally referred to as her "Cyberdears". (PROSE: Meet Missy!) Creating a paranoia that the minds of the deceased remain alive and conscious of what is happening to them, even after death, she created the 3W Institute, with the purpose of caring for the bodies of dead humans. (TV: Dark Water) The organization had facilities all around the world. (TV: Death in Heaven) Its main base of operations was in St Paul's Cathedral, (TV: Dark Water) hidden by use of dimensional engineering. (TV: Death in Heaven) A dying person's mind would be uploaded to a matrix data slice called the Nethersphere, where their emotions would be removed while their bodies would be upgraded into Cybermen. The people that paid the organization to preserve their bodies would be placed inside tanks filled with a substance called dark water to hide their nature as Cybermen, while their minds were uploaded. (TV: Dark Water)

In the ensuing 3W Institute Affair, (PROSE: Missy on Trial) the institute was discovered by Clara Oswald and the Twelfth Doctor while they were trying to find Danny Pink, who was also uploaded to the Nethersphere upon his death. Missy activated the tanks, and drained away the dark water, revealing the Cybermen. They were then released into the streets, (TV: Dark Water) flying into the sky and exploding over major populated areas, creating clouds to produce cyber-pollen for converting those who had not been preserved. Missy also planned for a next wave of pollen to kill and convert every human on Earth. The Cyber-Army was offered by Missy as a "gift" to tempt the Doctor to enforce "good" throughout the universe. This was rejected by the Doctor, who maintained that he was just "an idiot" who "help[ed] out" before handing control of the army to the cyber-converted Danny Pink, who had the Cybermen fly into the clouds and self-destruct, destroying both them and the clouds. (TV: Death in Heaven) Missy teleported away after the cyber-converted Brigadier Lethbridge-Stewart fired his wrist-blaster at her, powering her vortex manipulator. (TV: Death in Heaven, The Witch's Familiar)

Legacy
Missy claimed that Clara Oswald, her "latest minion", was "scarier" than her Cyberdears, as well as Nestenes and the Daleks. (PROSE: Meet Missy!)

A later incarnation,, used the resources of the Cyberium along with the corpses of Time Lords to create a new form of Cyberman, the CyberMasters, who he referred to as his "pretties". (TV: The Timeless Children)

Whilst looking into memories of aliens for Into The Unknown, Professor Maxwell Grey met some young people who claimed to have memories of "metal men" outside of St Paul's in 2014. He theorised this was an example of the Mandela Effect, as older witnesses recalled a similar incident occurring in the 1960s. (PROSE: The Mandela Effect, Or Monsters on the Streets of London)
