Borg unicomplex in Fluidic Space.png

A Unicomplex is a vast decentralized control structure spanning across hundreds of kilometers, used by the Borg Collective. The Borg Queen typically resides in unicomplexes, when not attending the assimilation of a new species from a Borg ship.


  • A unicomplex is discovered in the Delta Quadrant by U.S.S. Voyager's Delta Flyer in 2375.
  • In 2378, an alternate future version of Kathryn Janeway infects the Queen and complex with a neurolytic pathogen, leading to the Borg Queen proceed with the self-destruction of the Unicomplex to prevent the virus from spreading. This diversion allows Voyager to use the Borg Transwarp network to return to the Alpha Quadrant.
  • The steady decline of of Borg activity since the unicomplex destruction leads Starfleet to the assumption that the Borg threat has been eliminated permanently. In 2385 the Borg task force is dismantled. Annika Hansen resigns her Starfleet commission to protest the decision.
  • In 2410, a unicomplex has been constructed to serve as a command center for the Collective's invasion of the Alpha Quadrant. A second Unicomplex is also discovered in Fluidic Space.
