The second most popular villain in the TV show "Dr Who". The Cybermen were humanoids who began to replace parts of themselves with prosthetic devices in a quest to be stronger and longer-lived. In other words, cyborgs. Before they knew it, they had become
emotionless robot-like beings who converted other people by force, lobotomising them. In this respect they are precursors of Star Trek's Borg.
In Dr Who, the Cybermen
originally came from Mondas (in The Tenth Planet) but later settled on
the planet Telos. They have attempted to conquer and enslave Earth in many episodes. In the 2006 season of the show, they were seen evolving on a parallel Earth.
Off-screen, they were created by Script editor Gerry Davis and scientist Kit Pedler.
