Cyber-conversion

Cyber-conversion as named by the Mondasians, or Upgrading as known to Cybus Industries of an alternate universe, involves the physical and mental re-engineering of Human victims into Cybermen.

Mondasian Cybermen
Cyber-conversion involves the replacement of body parts, including limbs, organs, and vital systems, with artificial components. Partial conversion, with the victim retaining autonomy and a human identity and body parts, is possible.

Cybus Cybermen
Full conversion involves the transplantation of the brain in a Cyberman body (TS: Tardisode 6).

During the Battle of Canary Wharf, the Cybermen, needing reinforcements badly, quickly converted Humans into Cybermen by encasing Humans in cybernetic shells, as with Lisa Hallett. Hallett would have died if her lover, Ianto Jones had not managed to retrofit a cyber-conversion unit into life support for her. (TW: Cyberwoman)

Cybus Cybermen

 * John Lumic - Converted into Cyber-Controller
 * Sally Phelan
 * Jackie Tyler of an alternative universe - Alternate counterpart of Jackie Tyler
 * Yvonne Hartman - Torchwood Institute administrator
 * Lisa Hallett - Torchwood worker and love of Ianto Jones, partial cyber-conversion (TW: Cyberwoman)

Other
 * Miss Mercy Hartigan - CyberKing. Miss Hartigan refused to be converted to a standard Cyberman and took control of the Cybermen that landed in 1851. The Cybermen, however, had slowly set a plan in motion that would eventually make Miss Hartigan both a convert and a leader (DW: The Next Doctor)
 * Cybershade - Wraith-like creatures. A squadron of Cybus Cybermen fell into the 19th Century, from the Void, and for reinforcements they created Cybershades; due to the lack of technology in the Victorian Era, they could only manage primitive conversions. At least 16 of them were created (DW: The Next Doctor)

Mondasian Cybermen

 * Toberman- Partial cyber-conversion on Telos, regained his humanity and attacked the Controller. Sacrificed his life to close doors of the Cybermen's tombs (DW: The Tomb of the Cybermen)
 * Bates and Stratton - Cyber-conversion process failed at an early stage, after their limbs had been replaced by mechanical equivalents. Put to work on the surface of Telos with similar such failures. (DW: Attack of the Cybermen)
 * Lytton - Partial cyber-conversion on Telos, cyber-conversion incomplete at the time of his death (DW: Attack of the Cybermen)
 * Evelyn Smythe (alternative timeline) - (WC: / BFA: Real Time)
