Crane (Rise of the Cybermen)

Mr. Crane was a trusted employee and, perhaps, friend of John Lumic. He had worked with Lumic for many years and supervised with his plans on many occasions, including both the capture of homeless people and the cyber-conversion of the homeless into Cybermen. Crane turned on Lumic when the Cybermen almost "upgraded" Crane as well, and he confronted his old friend inside the Cyber Conversion factory where he angrily ripped out the life support systems built into Lumic's chair. Before more damage could be caused, Lumic's Cybermenn quickly came to his aid and threw Crane off, electrocuting him in the process. As a result, the Cybermen took Lumic away for an emergency upgrade, and the Cyber-Controler was born.
