"The Borg Collective is a vast civilization, estimated in the trillions, assimilating worlds and species, constantly growing and evolving. In 'Star Trek: Voyager,' they control 10,000 star systems and billions of individuals, hinting at trillions of Borg drones.
Whilst the Borg are primarily a nomadic space-bearing race they do however occupy planets with a typical population of nine billion drones primarily for the purposes of strip-mining the planets of all natural resources.
Other Borg ships, such as the Borg Sphere and Borg Tactical Cube, possess unique abilities and pose a significant threat to Starfleet. The Borg Queen's ship, known as the Singularity, is a more advanced Borg ship with the ability to tear a hole in space-time, showing the evolution of the Borg in the Star Trek universe.
There is no stated lifespan for the Borg; unless their ship or cube is destroyed they don't really die supposedly. Even the Borg Documentary doesn't have a lifespan for a Drone.
Only one Queen exists at any given time; when she is destroyed, a new Queen takes her place. In Star Trek: Voyager, it's revealed that the Borg Queen isn't a singular entity, but the name given to any that serves as its host, possessing all previous Queen's collective consciousness.
The "Good Borg", Jurati's Borg, were established in the Alpha Quadrant in the 21st century, when the queen from the alternate timeline and Jurati merged. The Borg that are assimilating the fleet in Picard season 3 are the "Bad Borg", not Jurati's Borg.
The Borg discover Species 8472 in the Delta Quadrant and try to assimilate its biotechnology, which is more advanced than anything the Borg have seen. The Borg quickly realize that Species 8472 is immune to assimilation and that contemporary Borg technology is no match for it.
With the unholy pact that Khan made, helping to design this ship, and his heightened intellect, Starfleet was able to secretly create one of the largest and the single most destructive forces in Starfleet's history.
In Endgame , Voyager used transphasic torpedoes to destroy three cubes. During the series, several other non cube vessels (probe vessel, sphere and Queen's diamond vessel) were also destroyed.
Although any further details would be purely speculative, it fits with the established canon and timeline that the ancient Romulans could've started experimenting with artificial life forms, accidentally created the Borg and realized the terror their experiments had given rise to.
Officially, the existence of a Borg homeworld is a hypothetical one as it has yet to be revealed in a canon Star Trek source. However, an identity for the Borg homeworld is given by the non-canon novel Lost Souls, which names it Arehaz.
The Borg queen was a member of Species 125. Note: This is NOT a PC and NPC rated species. Species 125 is the Borg designation for a species as yet unknown to the Federation outside of the Collective. However, it is likely that this species has been completely assimilated.
The Borg learn everything they know about an enemy through assimilating beings. The Borg couldn't assimilate Species 8472 because their immune systems were hyper-advanced.
The Borg, while still a powerful threat, are nothing compared to this type of power. The Q are not only able to defeat their entire race without breaking a sweat, but can also eradicate any trace of their existence altogether.
However Geordi said that Data was able to move faster than Borg drones, who couldn't move any faster than a human; while Data could move fairly quickly over almost any terrain (but he couldn't swim at that time).
It was later revealed that the Borg Queen was merely an avatar for the true power behind the Collective. The Destiny trilogy also mentioned that multiple Queens have been known to exist simultaneously in the Collective, but they all possessed the same agenda.
Admiral Janeway allows herself to be captured by the Borg Queen, so that she can implant a neurological pathogen into the Collective. The pathogen cripples the Collective, destroying the Queen's ship, and allowing the USS Voyager to ride through the Borg's transwarp corridor back to Earth.
Jurati returns as the Borg Queen. Upon returning from 2024 moments before the explosion, Picard canceled the auto-destruct and allowed the Borg Queen to proceed after realizing that it was the same Queen from an alternate timeline who had merged with Dr. Jurati.
The borg collective as a whole didn't join the federation it was just a small splinter group of the borg that joined the federation the main borg collective is still an enemy of the federation and would mostly likely never join the federation instead would keep on trying to assimilate the federation.
Originally Answered: Is the Borg Queen 7 of 9's mother? We know for a fact that she is not. The Queen was a member of Species 125, Erin Hansen was human and therefore a member of Species 5618.
The Queen was seemingly killed by the Enterprise-E crew before they returned to 2373. However, the Borg Queen was subsequently resurrected and returned in Star Trek: Voyager, where the crew of the USS Voyager did battle with her on multiple occasions while traveling through the Delta Quadrant.
