Tenth Planet - Cybermen

The Cybermen were once humans, but tried to combat their race's shortening life span with cybernetic surgery - replacing their bodily organs and limbs with mechanical versions. They also 'enhanced' their brains, removing the weakness of emotion. The result was the Cybermen - strong and efficient, not needing to breathe, but without fear or emotion, or humanity - Justin Richards, Monsters and Villains
