 Emblem of the Borg Collective | |
In the alternate mirror universe, the Borg were a race of cybernetically enhanced lifeforms which originated in the Delta Quadrant and spread, as the Borg Collective, throughout the galaxy, aiming to create a perfect race and bring order to the chaos of the galactic population by assimilating them—transforming them into drones of the Collective.
While the Borg in the alternate mirror universe had the same hive-like mentality, the same assimilation methods, and the same advanced technology as their primary universe counterparts, the similarities ended there. The Borg of the alternate mirror universe were proactively aggressive and attacked any intruder foolish enough to set foot on a Borg ship. Regardless of whether or not the intruder posed a threat to the ship, the Borg would use every resource at their disposal to assimilate the trespasser. In addition, while the Borg of the primary universe moved in a jerky, stiff-legged fashion, those of the alternate mirror universe were much quicker thanks to advances made in nanoprobe technology. Attempts to aim a weapon at a Borg, or avoid the injection tubules, were usually efforts in futility. In the alternate mirror universe, the Borg are ruled over by a Borg Queen.
Borg ships also differed in the alternate mirror universe, as they were much larger. The cubes measured 10 kilometers or more on each side, and they were equipped with a vast array of weapons that could easily destroy a Vor'cha-class cruiser with a single shot.
