Cyber-body

The Cyber-body, also known as the Cyber-suit (AUDIO: Real Time, TV: The Age of Steel) or cyber-form. (TV: Closing Time), was a suit of armour which functioned as the cybernetic body of the Cybermen. (PROSE: Doctor Who and the Tenth Planet) The Cybermen functioned through a Cyber-operating system. (TV: Nightmare in Silver)

Anatomy
The Sixth Doctor referred to the headpieces of these suits as the Cyber-helmet, (AUDIO: The Carrionite Curse) alternately known as Cyber-heads. (TV: Attack of the Cybermen) The Eleventh Doctor dubbed the severed arm of a Cyberman as a "Cyber-arm". (TV: The Pandorica Opens) Cyber-filament connected human brains to earpieces. (PROSE: Made of Steel)

Variants
The Cybermen created on Earth in Pete's World by Cybus Industries were humans whose brains alone were transplated into suits of armour. (TV: Rise of the Cybermen/The Age of Steel) However, when these Cybermen invaded the Earth of N-Space in the Battle of Canary Wharf, they took to upgrading whole bodies using local technology as a time-saving measure. (TV: Cyberwoman)

Becoming a space-faring power in N-Space, the Cybus Cybermen continued to upgrade whole bodies. In addition, the Cyber-suits themselves could operate independently in the event the organic components within perished. (TV: The Pandorica Opens) Other groups of Cybermen, appeared all but identical to Cybus' Cybermen, distingushed only by their chest armour which sported either faceplate outlines, (GAME: Blood of the Cybermen) or a generic plate in place of the Cybus logo. (TV: A Good Man Goes to War) Such Cybermen upgraded their victims by encasing them in Cyber-suits. (TV: Closing Time)

In an alternate timeline, the Cybermen used the resources of the Borg to upgrade several non-human races. While bearing the same basic form, variations existed according to species; Vulcans appeared much the same as humans, Judoon shock troopers retained their rhinoceros horns, Klingons bore faceplates modeled on their distinctive foreheads with extensions reminiscent of hair and chest plates bearing the insignia of the Klingon Empire, while Raxacoricofallapatorians stood tall with bulbous Cyber-helmets matching their heads and arms based on their three-fingered claws. (COMIC: Assimilation²)

Following the Great Cyber War, a new race of Cybermen emerged. Conversion could be initiated by cybermites (TV: Nightmare in Silver) or cybermites, and encompassed the whole body. (TV: Death in Heaven)

During the Siege of Trenzalore, the Cybermen employed a unit whose body was made out of wood. (TV: The Time of the Doctor)

Partial conversions
Tobias Vaughn received a partial conversion which saw his mind preserved within a cybernetic body which appeared externally human. (TV: The Invasion)

Rejected converts such as Eregous Bates and Lintus Stratton were humanoids fitted with cybernetic limbs. (TV: Attack of the Cybermen)

Partially converted on Telos, Gustave Lytton had a partial Cyber-suit applied to his body. Before his conversion could be completed, Lytton was killed defending the Sixth Doctor from the Cyber-Controller. (TV: Attack of the Cybermen)

Partially upgraded during the Battle of Canary Wharf, Lisa Hallett had a partial Cyber-suit applied to her body. The corpse of Dr Tanizaki, who was killed when Lisa attempted to upgrade him, was found with parts of a faceplate embedded into his own face. (TV: Cyberwoman)

Having undergone a partial conversion, Ashad's human body was housed in an incomplete, weathered Cyber-suit resembling those associated with the Cyberiad, (TV: Nightmare in Silver) but with an unique Cyber-helmet with an incomplete faceplate that exposed the left side of his face. He wielded a functional Cyber wrist blaster, though its energy could be drained by time hopping. (TV: The Haunting of Villa Diodati, Ascension of the Cybermen)
