Cyber-conversion involves the physical and mental re-engineering of Human victims into 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 Hallet. Hallet would have died if her lover, Ianto Jones had not managed to retrofit a cyber-conversion unit into life support for her. (TW: Cyberwoman)
