Alien Species
Cybermen

The Cybermen originally were Mondassians, Mondas being a twin planet of Mondas. The Mondassians evolved more quickly than humnans, specialising in cybernetics. Using their skills the Mondassians tried to extend their lifespan by replacing body parts with cybernetic components. Soon they had replaced almost every organ with machine, turning themselves into cold, ruthless, unemotional machines. Similar to the Daleks , the Cybermen were left with a strong desire to survive.

Mondas left the Sol system for unknown reasons, but it wasn't long before humans started to explore space and, inevitably, meet up with the Cybermen again. Alliances began sprining up in the fight against the Cybermen, and there have been many wars against the Cybermen.

Also like the Daleks, the Cybermen have had several redesigns. However, unlike the Daleks, Cybermen, being almost entirely machine, can co-exist with earlier, and future, selves.

The Cyberman, however, do have one major weakness: Gold is lethal. Gold coats their respiratory systems and effectively suffocates them. They are also not as well amoured as other creatures, although they do have great strength.

The Cybermen sometimes use another cyber creature known as a Cybermat. Ealier versions were much smaller, but just as deadly. The Cybermat is capable of jumping, and can be loaded with any kind of poison which it injects into the vitctims' necks.

All of the first seven of the Doctor's regenerations have met the Cybermen, meeting them throughout their evolution.
