In the movie Star Trek: First Contact, future Borg tried to contact their home world in 2063. If the communication was successful and the Borg from the Delta Quadrant came to Earth in 21st century, there'd be two Borg queens.

The Borg queens had individuality which represented the collective. And, technically all Borg were able to connect to both queens. How would the collective work then?

    What leads you to believe that all Borg in both Collectives would have been able to hear both queen's voices?

    Well, it really depends. If it's spring, the Borg drones should all be growing, in which case one of the Borg queens will leave the hive, "swarming" to a new location. There she'll mate with a drone, and the the worker Borgs will construct a new hive with wax secreted from their mouths. The circle of life. The Borg honey that is made in these first few weeks is especially prized by gourmets and foodies, but never as much as when it was made with the nectar of citrus blossoms.

    I think you'll find that time travel (or more specifically, the passage of time) does indeed make you different. Nov 27, 2012 at 3:06

    This, of course, assumes the Borg Queen existed in 2063. (Unless there’s a line somewhere indicating she did?) May 30, 2015 at 8:23

    “Time travel can't make you different” — great to have that question definitively settled. Dec 10, 2020 at 14:20

We actually have several examples of disconnected groups based on the same technology:

All of these were based in the same Borg technology, but the main Collective was unable to influence/break/fully reintegrate them without special assistance (and with the sub-collective, it didn't work at all).

In Unimatrix Zero, Part II we also learned that the hive mind allowed for instantaneous galaxy-wide transmission. Axum's ship was on the other side of the galaxy, yet there was no lag when he conversed with Seven.

This results in 2 main possibilities I can think of:

  • The two Queens were already in contact due to the hive mind, and command was relegated to the one on site.
  • The technology that created the hive mind had changed sufficiently enough in those centuries that the two collectives were incompatible and not (currently) in contact with each other.
    • I feel this one to be the most likely due to ENT 2x23, Regeneration, since the drones required sending a subspace message instead of using the hive mind to contact the main Collective.

If they were already in contact with each other, I suspect the two Queen minds would "fuse", sort of creating their own sub-collective. It could act rather similarly to the sub-collective from Survival Instinct - they were part of the whole, but could still separate themselves as a group from the whole.

And if they were not in contact with each other? In VOY 5x02, Drone, the Doctor's mobile emitter is accidentally combined with Borg technology to create a single Borg more advanced than the entire rest of the collective - and the Borg try to assimilate it.

Therefore, if two incompatible Borg Collectives existed, I would expect each one to try and assimilate the other. The more advanced Collective to gain more drones, and the less advanced one to make itself more advanced.

    Assuming that the Borg in the past had had the insta-comm tech, anyway.

I believe that had the future Queen's plan in First Contact succeed, the previously existing queen would have abdicated to the future one prior to merging the two Collectives (future drones with past drones). This is of course assuming that there wouldn't have been a way to merge the consciousnesses of them (if there was, then this question would be moot).

The future queen would have been "closer to perfection" than her present day counter part, having had the knowledge of more assimilated species and consequently being more technologically advanced. As the Borg's quest is to achieve perfection, it wouldn't make sense for an outdated queen to hang around.

And on the outside chance that the queens would be unwilling or able to reach a compromise and came to using conflict to settle the succession, and if the past queen won that conflict (most likely outcome due to superior numbers), then all the knowledge and experience of the future queen would have been instantly passed on to the past one upon assimilation.


Season one of Star Trek Picard establishes that each cube has the capability as serving as a Queen's headquarters, and that any drone could serve in the role. Typically a pre-selected one--as the Queen indicated Seven had been identified as a potential Queen on Voyager--but given that Hugh fully expected to be able to fill the role on Picard, probably any drone could do it in a pinch: it's just that any random drone wouldn't have the self-volition to take the initiative.

This being the case, that the Borg had prepared for the possibility of having to elevate a drone to Queen on an emergency basis, suggests they also considered the possibility of multiple Queens caused by, say, a large-scale network failure that isolated sections of the Collective and how to reintegrate them back in. If that were true, then they'd have some kind of procedure to handle it. The First Contact situation would simply be a variation in which the separation between the main Collective and the isolated sub-Collective was temporal rather than spatial, and they'd handle it however they would handle the more mundane version.

    I don't think individual drones could be take place of Queen. Individual drones are dumb without the collective and they don't have necessary implants to interface. The Seven is different. She had free will/ thought process. She had special implants since childhood.

  • The Queen was a member of a species that has a special capacity to "bring order to chaos". Seven is apparently sufficiently capable of tricking a single damaged cube into thinking that she's the queen, but it seems unlikely that she'd have the ability to serve as a full queen.
