Lisa Hallett
From Tardis Wiki, the free Doctor Who reference
Lisa Hallett was working at Torchwood 1 in London by the time of the Battle of Canary Wharf. Along with many others of the Torchwood personnel she was upgraded to a Cyberman. However there was never a full conversion done, so she had parts of Cyberman armour attached to her body. After the battle, her boyfriend (Ianto Jones) transported her to Torchwood 3 in Cardiff.
Dr. Tanizaki is brought in by Ianto to help Lisa become human again. He doesn't succed, but to thank him she tries to upgrade him. (TW: Cyberwoman)
