The Cybermans have often used “cyberpets” in their conquest of Croydon and the many gravel mines of the UK. Like Cybermen themselves, their pets are sometimes said to be mechanically and electronically enhanced animals, although really makes no sense; why would Cybermen be wasting time constructing cyberanimals instead of, say, installing some great-ass electronic brains into them instead that could support Cyberbrain downloads or something? This would free them of having to kidnap and “cyberrape” humanoids, which might go a long way towards making them less feared by folks round the galaxy and stop that whole “getting kilt by The Fucking Doctor all the time” issue as well. And think how cool those CyberAnimalMen could be! Cyberkoalas, Cyberslugs, Cyberbeavers, Cybergiantcoconutcrabs!
