Cyber-arm

Cyber-arm were used to describe the arm parts of the Cyberman, as part of its Cyber-body. Like the rest of the Cybermen, the arms were replaced by the original inhabitants of Mondas when they became weak.

The Cyberman from Pete's World had concealable Cyber wrist blasters on their right arms. (TV: Army of Ghosts/Doomsday) One parallel universe Cyberman had both its head and an arm severed whilst guarding the Pandorica. Despite this the seperate parts were still active, including its severed Cyber-arm. The Cyber-arm was also able to fire its wrist blaster. (TV: The Pandorica Opens)

The Cybermen that appeared in Hedgewick's World of Wonders had larger Cyber wrist blasters that were a permanent fixture. The same Cybermen were to separate some of its different parts, including its hand, for the use of attacking and ambushing. (TV: Nightmare in Silver)

The Cyber-Warriors and the CyberMasters also featured the same blasters on their right arms. (TV: Ascension of the Cybermen/The Timeless Children)
