Cybershade Sixteen

Cybershade Sixteen was a Cybershade used by the Cybermen in 1851. The Cybermen converted a cat or a dog into a Cybershade. Jackson Lake (thinking he was the Doctor) had been hunting him since 10 December that year. Rosita (Jackson's companion) had spotted him coming out of a warehouse a fortnight later and called "the Doctor". The Tenth Doctor having just materialised responded as well. Rosita threw a rope over him and Jackson and the Doctor held on when the Cybershade ran up a wall. The Doctor and Jackson still held on when he ran threw a window, over the floor and out the other. Rosita cut the rope with her axe and the Cybershade ran off into the distance. (TV: The Next Doctor)
