Borg

The Borg, a civilization based on perfection and the assimilation of information. There are many theories on where the Borg came from, like Voyager 6 (also known as V'Ger) and mad scientists from the Delta Quadrant, but all we know is they originated in the Delta Quadrant. They're at least 300 years old, but our first documented chronological encounter with them was on April 5, 2063, when they traveled back in time and tried to stop first contact with the Vulcans. The Enterprise-E traveled back also and stopped them, but if the Borg would have succeeded Zefram Cochrane would never have made his historic first warp flight. We would never have made it into the final frontier and Earth would have been assimilated. Sometime in the 22nd century, Enterprise NX-01 was said to have met a cybernetic race twice but there is no clear records from that era. By the 2350s rumors of an alien race called "The Borg" had reached the Alpha Quadrant, which inspired Magnus and Erin Hansen to set out in search of them. Their research took them all the way to the Delta Quadrant before their assimilation in 2356. Their daughter Annika was also assimilated. 8 years later in 2364 there were unexplained attacks along the Neutral Zone later found to be the first signs of Borg activity in the Alpha Quadrant. One year later, Q hurled the Enterprise-D into System J-25 where the Enterprise's crew started to get a feeling of what they were up against. Another year later, in 2365, a Borg cube was headed to Sector 001 where they captured Captain Jean-Luc Picard and assimilated him into there collective. They did it so there collective could have a leader, but Picard resisted and the Enterprise rescued him. The Borg cube was eventually destroyed. In 2373, the USS Voyager witnessed a war between the Borg and Species 8472. Voyager formed an alliance with the Borg so they could get save passage through Borg space, in return Voyager would help the Borg fight the war. The alliance went well until Voyager found out that the Borg started the war, Voyager stopped the alliance but came back with the Borg drone Seven of Nine. Seven of Nine was formally known as Annika Hansen, Voyager helped her regain her humanity. Voyager had faced the Borg a few more times but there final encounter was when they used technology from the future to get past the Borg, go threw a transwarp conduit, and damage the collective badly. No one knows was has become of the Borg, they haven't attacked for 3 years, but will they be coming...
