Cybershade

Cybershade 16 was a Cybershade.

Biography
Created by the Cybermen when they first landed in victorian London, Cybershade 16 was an animal (possibly a dog or cat) that had been converted into Cyber form. Unlike other Cyber variants, it had the abilities to run faster than it's masters and scale walls. Proved to be very strong, it pulled the Doctor and Jackson Lake up and building, and then across a building, whilst still running at full speed. It later reported clips of these events through video feed back to the Cybermen (The Next Doctor). Other than the Cybermen, it was also under the control of Miss Hartigan as she later requested it's help (The Next Doctor). It is presumptuous that Cybershade 16 took part in the funeral massacre by rounding up humans for deletion (The Next Doctor).
