Cybershades were rug-like creatures with bronze Cyber-heads. Like their Cyberman superiors, they had piping like handlebars connected to their heads, except they angled diagonally like the ears of an animal.
The Cybershades had the brains of cats or dogs and were unable to speak or obey complex commands. They seemed unable to run upright. They were only seen to run on all fours or bent over low. tardis.wikia
