Crane (Rise of the Cybermen)

Mr Crane was John Lumic's right-hand man and deputy.

Having worked alongside Lumic for many years, he realised how ruthless he could be, and was just the same himself; Crane had no conscience when fooling homeless people into believing he would supply them with free food, when, in actuality, it was merely a con to have them converted into Cybermen. (TV: Rise of the Cybermen)

Later that night, Lumic reprogrammed the EarPods into blanking everybody's mind, and lured them into Battersea Power Station, ready for cyber-conversion. Crane realised it was meant to include him and ripped out his EarPods as he didn't want to become a Cyberman.

This didn't completely thwart Lumic however, as Cybermen took him to Lumic for being "unprogrammed". There, Crane tried to kill Lumic by damaging his wheelchair's life-support systems, but was electrocuted by a Cyberman. Ultimately, as a result of Crane's actions, the Cybermen took Lumic away for an emergency upgrade and the Cyber-Controller was created. (TV: The Age of Steel)

Behind the scenes

 * Crane's exercise of control over people implanted with EarPods is later repeated by Mercy Hartigan. Each ordered their victims to turn right, then left.
