Seven of Nine is a fictional character in the Star Trek franchise, specifically in Star Trek: Voyager played by actress Jeri Ryan. She is a former Borg drone who joins the USS Voyager crew after being liberated from the Borg Collective. She first appeared in the show’s fourth season and remained a cast regular until the end of the series. The character returned for the new show Star Trek: Picard.
Seven of Nine (born as Annika Hansen) is the daughter of Magnus and Erin Hansen, exobiologists renowned for their groundbreaking research of Borg technology and culture. This led them to an expedition into the Borg collective to gather intel firsthand. As a result, the Borg assimilated Seven at a young age, and as a Borg drone, she served the Collective until the crew of the USS Voyager freed her, restoring her individuality and personal freedom. Throughout the series, Seven undergoes a profound journey of self-discovery, largely centered on her identity, humanity, and relationships with others.

A major part of Seven of Nine’s character development is the portrayal of her bisexuality and relationships. While on the USS Voyager, Seven forms a deep connection with various crew members, including Lieutenant Commander Chakotay and Captain Janeway.
In the series Picard, which takes place 20 years after Voyager, we see Seven develop a relationship with Raffi, a female Starfleet officer. They look into each other’s eyes — and while the camera pans out — we see them holding hands. Fans and audiences alike took this moment as an opportunity to ask if Seven was bi. Of course, Jeri Ryan took to X to respond and clarify:
Oh, Seven is canonically bi, don’t you worry.
