Cybermen

Cybermen are fictional characters from the "Doctor Who" series, depicted as humanoid robots or cyborgs created through the conversion of humans into more technologically advanced beings. They are characterized by their metallic, robotic appearance and are driven by a desire to upgrade or "improve" living organisms, often at the expense of their individuality and emotions. Their goal is typically to achieve a form of uniform perfection, making them relentless and often antagonistic opponents to the Doctor. Essentially, Cybermen represent a fusion of biology and machinery, exploring themes of technology’s impact on humanity.
