Warning: SPOILERS for Star Trek: Picard season 1, episode 5
Seven of Nine's (Jeri Ryan) tragic backstory in Star Trek: Voyager, Trekkers rejoiced when it was announced Seven would appear in Star Trek: Picard and meet Jean-Luc Picard (Patrick Stewart) for the first time. Their inaugural encounter was indeed a thrill, but Star Trek: Picard episode 5, "Stardust City Rag," also revealed that Seven's years since the U.S.S. Voyager returned to Earth have been laced with heartbreak, misery, and death. This sordid state of affairs means Seven of Nine's story demands to be told in full.
Introduced in the "Scorpion" two-parter that transitioned Star Trek: Voyager's seasons 3 and 4, iral Janeway made a cameo in 2002's Star Trek: Nemesis, Seven was not seen again in Star Trek canon until she beamed aboard Jean-Luc's new starship, La Sirena, at the end of Star Trek: Picard episode 4, "Absolute Candor". However, as the next episode revealed, Seven is now a changed woman after her grim experiences over the last 20+ years.
After the banned all artificial lifeforms in the Alpha Quadrant. As a reclaimed Borg from the Delta Quadrant whose body still harbored countless cybernetic implants from her time in the Collective, this sweeping policy change directly affected Seven of Nine, and it's quite possible the ban forced her to leave Federation space. When the Beta Quadrant was plunged into chaos after the supernova and the Federation's withdrawal from their planned mission to rescue the Romulan people - which Picard was to lead - Seven traveled to the Romulans' space sector. There, the ex-Borg ed the Fenris Rangers, a vigilante outfit that protected helpless Romulans from being victimized by the pirates and warlords taking advantage of the fall of the Romulan Star Empire. By the time Seven meets Picard, she's been a Ranger (essentially a space sheriff) for 13 years - a life she finds "hopeless, pointless, and exhausting," but necessary to save those in need.
However, Seven suffered a tragic loss in 2386 when Raffi Musiker (Michelle Hurd), ire the thankless job Seven and the Rangers perform.
What Seven of Nine's stunning appearance in "Stardust City Rag" made clear is that she needs her own Star Trek spinoff to properly portray Seven's adventures. Not only does Jeri Ryan still possess the "It" factor and boundless charisma, Seven of Nine is one of the few marquee Star Trek characters from the 1990s who could (and should) headline their own series. In fact, Seven's climactic phaser battle in "Stardust City Rag," where she executed Bjayzl and took on her soldiers while hefting double phaser rifles, shows that she has transformed into a truly badass action hero - whom a Star Trek series could easily be built around. The ragtag heroes of the Fenris Rangers could also be a fascinating counterpoint to the darker Star Trek: Deep Space Nine, making fans dreams come true as it explores Seven's place in the Romulans' tumultuous and dangerous galaxy.
As the Star Trek franchise expands on CBS All-Access, it's been reported that there are other spinoffs in development to Star Trek: Discovery, Star Trek: Lower Decks, and Star Trek: Picard. One of them should be a full-on action-adventure series about Seven of Nine and the Fenris Rangers that would take Trekkers to an all-new, exciting and dangerous frontier.
Star Trek: Picard streams Thursdays on CBS All-Access and Fridays internationally on Amazon Prime Video.
