THE BORG
When the Enterprise confronted a Borg cube, Captain Jean-Luc Picard was captured and assimilated. Known as Locutus, Captain Picard was to be the spokesman to the human race from the Borg. The message from Locutus was simple. Resistance is futile. However, the crew of the Enterprise rescued Captain Picard and destroyed the Borg ship.
After being stranded in the Delta Quadrant, the USS Voyager passed through Borg space on its long journey back to the Alpha Quadrant. While there, the crew of Voyager encountered Seven of Nine, a human female who had been assimilated as a young girl. After assisting the Borg in their battle with Species 8472, the Voyager crew successfully severed the link between Seven of Nine and the Borg collective. After a difficult transition, Seven has become a valuable member of the Voyager crew.
The Borg are a race of cybernetic beings mostly humanoid. They have combined flesh and machine and function as one. This connection has allowed the Borg to become the most feared foes in the galaxy. They seek to conquer other races by assimilating them into their collective. Once assimilated, the individual is lost to the hive mind of the collective.
