Seven of Nine

Annika Hansen and her family were assimilated by the Borg when she was still a young child, in 2348. Her mother and father were famous Federation scientists. They took their ship, the S.S. Raven NAR-32450, and headed toward the Delta Quadrant to conduct scientific research and were never heard from again. After assimilation she became known by the designation "Seven of Nine, Tertiary Adjunct of Unimatrix Zero-One". Seven of Nine's interplexing beacon has a translink frequency of 108.44236000.

In 2374, Seven of Nine became the liason between the Borg and the U.S.S. Voyager during a joint operation to defeat Species 8472. In exchange for information about Species 8472, the Borg were to grant Voyager safe passage through the vast Borg space. Seven of Nine joined the Voyager crew when her connection to the Borg Collective was severed after her Borg cube was destroyed by Species 8472 bioships. Voyager's EMH Doctor removed many of the Borg implants and her human characteristics are resurfacing. Seven currently has approximately 18% of the Borg implants still functioning, including her cranial and occular implants. Even though she is becoming more human, she prefers to be called Seven of Nine, and not Annika.
Introductory Medical Notes: EMH Doctor, AK-1
The Borg formerly known by the designation "Seven of Nine" has been disconnected from the Borg collective mind through the neutralization of the upper-spinal column neurotransceiver. In total, I have extracted eighty-two percent of her Borg hardware implants. The remaining bio-implants have been stabilized and remain critical to her life support. I have also stimulated her human metabolism and immune system, though the Borg Nanobots in her bloodstream will more than suffice until she has stabilized. Hair follicles have been repaired and stimulated. Left eyepiece has been replaced by an artificial organ replacement, simulating her own organic eye.

Starfleet records indicate that Seven of Nine was formerly Annika Hansen. Annika's parents were last reported to be leaving a remote outpost in the Omega sector, headed towards the Delta Quadrant in a small vessel The Raven. It is possible that the Hansen family were the first humans to be assimilated by the Borg.
