The Borg are a fictional alien group that appear as recurring antagonists in the Star Trek franchise. The Borg are a vast collection of “drones”, or cybernetic organisms, linked in a hive mind called “the Collective” or “the Hive”. The Borg co-opt the technology and knowledge of other alien species to the Collective through the process of “assimilation”: forcibly transforming individual beings into drones by injecting microscopic machines, or nanoprobes, into their bodies and surgically augmenting them with cybernetic components.
The Borg’s ultimate goal is “achieving perfection”. Aside from being recurring antagonists in the Next Generation television series, they are depicted as the main threat in the film Star Trek: First Contact. In addition, they played major roles in the Voyager series and serve as the way home to the Alpha Quadrant for the isolated Federation starship USS Voyager.
The Borg have become a symbol in popular culture for any juggernaut against which “resistance is futile”.
