Borg

A borg Drone.

Generally humanoid in appearance, the Borg implant themselves with cybernetic devices, or "implants" granting them superior technological and combat capabilities. Different Borg are equipped with different hardware to perform specific work tasks. The Borg exhibit a high degree of intelligence, granting them vast adaptability in their tactics. The Borg operate by conquering entire worlds, through a process known as "assimilation". It is important to note that the Borg do not select only those worlds which will augment their "perfection", they simply destroy the civilizations they encounter. Individual members of assimilated races are implanted with sophisticated cybernetic implants, permitting each individual to perform a specific task as required by the Collective. Thousands of species have been conquered in this fashion.
