Mechanising Worm

Mechanising Worms, also known as Mechanisation Worms, were metal worm-like creatures used by the Cybermen of the Cyber-Mainframe. (AUDIO: Telepresence, Code Silver) They closely resembled the worm-like variants of the N-Space Cybermats. (TV: Revenge of the Cybermen, AUDIO: Sword of Orion)

Physical characteristics
As their name implied, Mechanising Worms resembled silver, metal worm-like creatures with segmented bodies. Although small in size, Mechanising Worms were strong enough to restrain fully-grown humans; (AUDIO: Telepresence) even Josh Carter, a human with Auton physiology, compared being attacked by Mechanising Worms to being "hugged by a hoard of boa constrictors". Despite their strength, however, Mechanising Worms could be swiftly destroyed by a sufficiently powerful laser cutter. (AUDIO: Code Silver)
