Borg (species)

The Borg were a cybernetic species from a parallel universe.

Technology
Like the Cybermen, the Borg possessed a fleet of starships used to assimilate other life. Borg ships were modelled on basic shapes, such as cubes and spheres. (COMIC: Assimilation²)

History
In the 24th century, the Borg, who came from the Delta Quadrant, assimilated Federation Captain Jean-Luc Picard (renaming him Locutus of Borg) and attacked Starfleet at Wolf 359. Starfleet suffered heavy losses in the battle, but eventually Picard was rescued by the crew of the USS Enterprise and regained his original personality.

Later in the same century, the Borg entered into an alliance with the Cybermen from the Doctor's universe, due to their completely identical motives and goals of assimilating organic species. On Stardate 45635.2, their joint assault force attacked the Federation planet Delta IV. (COMIC: Assimilation²)

Alternate timeline
In a possible future shown to Picard by the Doctor, the Borg were conquered by the Cybermen, who thus became powerful enough to cyber-convert all major civilizations of both universes.
