Enterprise-D in 2365, in spite of that species' below-average cranial capacity and other physiological limitations. The assimilation of the human race has been an elusive goal of the Borg since its first encounter with the U.S.S. That Queen apparently died in 2378, when a neurolytic pathogen was introduced into the Hive and wreaked havoc on a massive scale.ДЄt this time, it is not known if the Queen was subsequently replicated, or even if the Borg Collective survived the pathogenic attack. If so, she was replaced by another virtually-identical successor, whom Voyager once again encountered, in 2377, at a time when the so-called 'Unimatrix Zero' phenomenon threatened the integrity of the Collective.

The Borg Queen Vessel was destroyed during that incident however, it is not clear if the Queen herself was still aboard at the time. Voyager in the Delta Quadrant when that Federation crew attempted to procure a transwarp coil. This Queen was soon replaced by another, almost identical one - a drone assimilated from Species 125 - who encountered the U.S.S. Enterprise-E, not only did the plan fail, but the Queen and all other Borg involved - who were occupying the Enterprise at the time - were killed when plasma coolant liquefied their organic components. However, due to interdiction by the U.S.S. In 2373, the Borg Queen spearheaded the Collective's attempt to alter Earth's history in order to make humanity easier to assimilate. The Hansens were assimilated before they could transmit their findings to Starfleet, but the information was later recovered by the U.S.S. The earliest Federation data on the Borg Queen was collected by Magnus and Erin Hansen, two exo-biologists who spent several years studying the Borg in the 2350's aboard their science vessel, the U.S.S. Therefore when she speaks as 'I,' she is presumably referring to all previous manifestations of the Queen, going back probably thousands of years. (It is not clear whether more than one queen exists simultaneously, or if a new queen is created when the old one dies.) The Borg's collective nature makes it likely that each Borg Queen has all her predecessors' (and/or counterparts') qualities and memories. Apparently the Borg Queen has been destroyed on a number of occasions, but another queen always seems to take her place. Information on this being is still very limited. When she emerges, she will 're-assemble' herself into a predominantly artificial body - the arms, legs and torso appearing to be entirely synthetic, while the head and shoulders seeming to be organic, but with substantial cybernetic implants. The Queen spends much of her time in her 'lair' with her head and spinal column residing in a special alcove. In her own words, she is the 'one who is many.' But for the Borg Queen the concepts 'I' and 'we' are interchangeable. She is usually the one who 'speaks' for the Collective in situations where contact with outsiders is best conducted by an individual. The Borg Queen has a unique personality and a sense of individuality that normal Borg drones are not allowed. She resides primarily at Unimatrix One in the Delta Quadrant, but will often leave this home base to participate in assimilation efforts of a special nature. She brings order to the legions of voices within the Hive mind and provides a common direction - much like the queen of an insect colony. The enigmatic Borg Queen is the central locus of the Borg Collective.
