Which Borg drone later joined the USS Voyager crew? Seven of Nine was the Borg drone who joined Voyager’s crew.

Born Annika Hansen, she was assimilated by the Borg as a child and spent years within the Collective. Voyager encountered her in 2374 during a conflict involving the Borg and Species 8472. After Voyager severed her connection to the Collective, Captain Kathryn Janeway accepted her aboard the ship.

Seven retained Borg implants, enhanced strength, and extensive technical knowledge, but gradually recovered parts of her individuality. Janeway became a demanding mentor, while Seven’s relationship with the crew explored identity, autonomy, and whether someone shaped by the Borg could reclaim a human life.

Seven is often confused with Kes because both became important members of Voyager’s crew, but Kes was an Ocampa civilian and left the ship earlier. Neelix was a Talaxian, and the Doctor was Voyager’s emergency medical hologram. Seven’s full designation was Seven of Nine, Tertiary Adjunct of Unimatrix 01.
