Cybermen

The Cybermen are a fictional alien race of cyborgs from the British science fiction television programme Doctor Who. They are one of the Doctor's most persistent and recurring enemies. The Cybermen are characterized by their emotionless nature, their cold logic, and their relentless pursuit of their goal: to convert all organic life into more Cybermen. They originated on the planet Mondas, the twin planet to Earth, but have since appeared in various forms and from different origins across the universe and through time.

Their appearance typically consists of metallic bodies, often with a helmet covering their heads and exposed facial features or metallic replacements. Over the decades, their design has evolved significantly, reflecting advancements in the show's production. The Cybermen's methods involve removing organic parts and replacing them with cybernetic components, often forcibly, and they are known for their efficient, if brutal, approach to conquest and survival. Their ultimate aim is the eradication of all emotion and individuality, believing it to be a weakness.

The Cybermen have a long history within the Doctor Who canon, first appearing in the serial "The Tenth Planet" in 1966. They have been portrayed by numerous actors and performers throughout the show's history, and their motivations and origins have been explored and reinterpreted across different eras of Doctor Who. Their continued presence highlights themes of humanity, identity, and the dangers of unchecked technological advancement and the suppression of emotion.
