Crane (Rise of the Cybermen)

Mr. Crane was John Lumic's right-hand man, and perhaps a friend.

Biography
He supervised the capture of homeless people and their cyber-conversion into Cybermen. The Cybermen almost "upgraded" Crane as well, so he damaged the life support systems built into Lumic's chair, resulting in Lumic being "upgraded". However, the Cybermen killed Crane before he could do more damage.

Ultimately, as a result of Crane's actions, the Cybermen took Lumic away for an emergency upgrade, and the Cyber-Controller was created.

Behind the scenes

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