Profile

Physical characteristics

Variants

From early in the Cyberman's history before they froze themselves on Telos, some variants had crystalline eyes and antennae through which they receive commands. These Cybermats Cybermats tended to resemble oversized metallic silver fish and have segmented bodies with cilia-like tactile sensor probes along the base of their heads. Some, though not all, small Cybermats of this kind could easily fit in the palm of a humanoid hand. (DW: 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 crystalline based eyes. Otherwise they looked similar. (DW: The Wheel in Space)

When the Cybermen infiltrated Nerva Beacon in a plot to destroy Voga the Cybermats had segmented, eyeless, flat worm-like bodies without cilia. (DW: Revenge of the Cybermen)

Cybermen from the 30th century who traveled back to 1940 also employed Cybermats and harvested Humans to make more of them. (PDA: Illegal Aliens)

Weaknesses

Cybermats shared the Cyberman's weakness for gold. (DW: Revenge of the Cybermen) They could also be disabled with electric charges. (DW: The Tomb of the Cybermen)

History

The Cybermats originated on Mondas during the earliest phases of Cyberman history, when most of the planet had not yet converted. (BFA: Spare Parts)

The Cyber-tombs on Telos had tunnels for the Cybermats to move out through from the tombs into the main control rooms. (DW: The Tomb of the Cybermen)

Some accounts show that the Cybermats were created by Cybermen using bodies (or parts of bodies) of humanoids not suitable for Cyber-conversion; very young children or babies. (PDA: Illegal Aliens, BFBS: The Crystal of Cantus)

Behind the Scenes

Cybermats were realized in the studio by a number of techniques including clockwork and radio-controlled models. In some shots they were pulled by wires or simply pushed into shot. Shots of the Cybermats leaping onto their victims were achieved buy pulling the Cybermat away via wires and then playing the film backwards.
