Physical characteristics Edit
The various types of Cybermat seen so far have all had a metallic body, usually segmented. Some types have had eyes, some mouths, and some have had cilia. At least one type had visible organic teeth.
By some accounts, the Cybermats were created by Cybermen from bodies or body parts of humanoids not suitable for Cyber-conversion: pets, very young children and babies. (AUDIO: Spare Parts, PROSE: Illegal Alien, AUDIO: The Crystal of Cantus)
Early in the Cybermen's history, before they froze themselves on Telos, some variants had crystalline eyes and antennae through which they received commands. These Cybermats resembled oversized metallic silverfish. They had segmented bodies with cilia-like tactile sensor probes along the bases of their heads. Some, though not all, Cybermats of this kind could fit in the palm of a humanoid hand. (TV: The Tomb of the Cybermen)
In the 21st century, when the Cybermen attempted to infiltrate Space Station W3, they had photoreceptors for eyes rather than crystal-based eyes. Otherwise they looked similar to the kind seen on Telos. (TV: The Wheel in Space)
Also in the 21st century, a type of Cybermat that was buried beneath Colchester could drain electrical energy from the lights in town. This Cybermat had black, teardrop-eyes like Cybermen and an opening mouth with organic teeth. (TV: Closing Time)
Another variant was a sleeker and more high-tech version of the Telosian Cybermats. Unlike the Telos version, these Cybermats were purposed with biting humans and infecting them with a virus, much like the Cybermats at the Nerva Beacon. However, instead of being deadly, the virus mutated flesh into metal and the victims became Cyberslaves. (GAME: Blood of the Cybermen)
Cybermats shared the Cybermen's weakness for gold. (TV: Revenge of the Cybermen) They could also be disabled with electric charges, (TV: The Tomb of the Cybermen) although this weakness seems to have been eliminated later; one was used to siphon electricity from power sources instead. The same model proved vulnerable to the sonic screwdriver, which was able to either stun or fry the Cybermat memory. (TV: Closing Time) They could also be disabled with a sonic pulse, using an amplifier. (GAME: Blood of the Cybermen)
On GSO Arctic Drilling Station in 2010, most of the crew had been converted into Cyberslaves by the Cybermat's nanovirus. The Eleventh Doctor repelled the Cybermats with a specific frequency on a sonic amplifier device and found a cure for the nanovirus to treat Chisholm. (GAME: Blood of the Cybermen)
Several centuries before 2011, a group of Cybermen crashed on Earth. A Cybermat was used to drain electrical energy for the crashed Cybership so they could begin full Cyber Conversions. One was named Bitey by the Eleventh Doctor for its organic mouth; the Doctor reprogrammed it to drain power from the Cybership, but a Cyberman stepped on Bitey, destroying it. (TV: Closing Time)
In 2503, a Cybermat smuggled itself aboard the Vanguard and began sabotaging its systems. Vol shot it, disabling its weapons, but the Cybermen reprogrammed it to take control of the crew's minds. (AUDIO: Sword of Orion)
Behind the scenes Edit
- Wood lice inspired the creation and look of the Cybermats. In their first appearances in The Tomb of the Cybermen and The Wheel in Space, they were realised in the studio by a variety of techniques, including clockwork and radio-controlled models. In some shots they were pulled by wires or simply pushed into view. Shots of the Cybermats leaping onto their victims were achieved by pulling the Cybermat away with wires and playing the film backwards.
- Cybermat effects in Revenge of the Cybermen used a combination of strings, puppetry and CSO which did not look very convincing. The Cybermats (or rather the single Cybermat which appeared) went through a radical re-design and resembled a cybernetic silverfish.
- According to The Brilliant Book 2011, a reference book that is not considered a valid source on this wiki, on 30 November 1879 at Blenheim Palace, the Fourth Doctor was hunting Cybermats while posing as a Punch and Judy man for Winston Churchill.
