Seven of Nine first appears in the “Star Trek” franchise during Season 3 of “Star Trek: Voyager.” In the episode “Scorpion, Part II,” Seven meets the USS Voyager crew once they form an uneasy alliance with the Borg. This eventually leads her to remain aboard the USS Voyager, becoming a part of the ship’s crew and a major ally in their efforts to return home. Following the 2001 end of “Voyager,” she disappears from the “Star Trek” spotlight, only to make a surprise return in 2020 via the Paramount+ series “Star Trek: Picard.”

On the “Star Trek: The Next Generation” sequel, Seven reemerges in the Season 1 episode “Absolute Candor.” She goes on to appear throughout much of Season 1 as well as the entirety of Seasons 2 and 3. It’s revealed that after the events of “Voyager,” she joined the vigilante group known as the Fenris Rangers, who maintain some semblance of law and order in and around the former Romulan Neutral Zone. After working with Admiral Jean-Luc Picard (Patrick Stewart), Seven officially joins Starfleet and takes command of the USS Enterprise, formerly known as the USS Titan.

Though Seven’s death would’ve packed a major emotional punch in the “Voyager” finale, had she given her life to help the Voyager crew, she wouldn’t have had the chance to shine on “Picard.”
