CyberTelosian

The CyberTelosians were an offshoot of Cybermen originating from the CyberFaction's colonisation of Telos.

Characteristics
The CyberTelosians were slim and spoke in a monotone, buzzing voice, emphasising their lack of emotion. (TV: The Moonbase, The Tomb of the Cybermen)

A fatal weakness to the Telosian Cybermen was the combination of solvents known as Polly Cocktail. (TV: The Moonbase)

Technology
CyberTelosians could produce arcs of electricity from their hands to stun, disable and kill. (TV: The Tomb of the Cybermen) They also possessed a cyber-cannon] that could operate in the vacuum of space. The virus Neurotrope X was used by the Telosians to incapacitate humans. (TV: The Moonbase)

History
On 15 October 2070, the Telosian Cybermen attempted to destroy the Earth in order to eliminate humanity, whom they saw as a potential threat to the Cyberman Empire, as well as gaining retribution for the destruction of Mondas. However, this attack was thwarted by the Second Doctor. (PROSE: Doctor Who and the Cybermen, TV: The Moonbase)

The Cybermen had all but passed into legend when an archaeological expedition to the Telos found the CyberTombs, where hordes of Cybermen waited in cryogenic suspension led by the Cyber-Controller. They were awakened but defeated by the Second Doctor. This tomb was sealed again (TV: The Tomb of the Cybermen) and re-activated by CyberNeomorphs (TV: Attack of the Cybermen). It was also not the only CyberTomb. There were dozens across the galaxy and more wars were started off. (AUDIO: The Crystal of Cantus)
