Borg (AMU)

In the alternate mirror universe, the Borg were a race of cybernetically enhanced lifeforms which originated in the Delta Quadrant and spread, as the $𝜇$, 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 mirror universe had the same hive-like mentality, the same assimilation methods, and the same advanced technology as their prime universe counterparts, the similarities ended there. The Borg of the 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 prime universe moved in a jerky, stiff-legged fashion, those of the mirror universe were much quicker thanks to advances made in nanoprobe technology. Attempts to aim a weapon at a mirror 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 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 cruiser with a single shot.
