Warning: SPOILERS for Star Trek: Picard season 3Star Trek's Borg Queen is one of the franchise's most well-known villains, with a long and complex history. Before the Queen's introduction in Star Trek: First Contact, the Borg were thought to operate as a hive-mind species with no de facto leader. However, First Contact established the Borg Queen as their true leader, in a position very similar to the queen of an insect colony. Unlike the rest of the Collective, the Borg Queen acts as an individual, making her very different from the other Borg and a terrifying adversary with the entire Collective at her disposal.
While the Borg Queen has become a controversial character, the franchise has continually used her to its advantage since her introduction. The Borg Queen has appeared in multiple Star Trek projects since Star Trek: First Contact, most notably Star Trek: Voyager and Star Trek: Picard. Voyager helped flesh out the Queen's backstory and added a lot to her lore, while Picard definitively concluded the original Borg Queen's storyline but left the door open for a newer incarnation of her to appear in future projects. All of the Borg Queen's appearances in the franchise have contributed to her complex and sometimes confusing history.
The History Of The Borg Queen In Star Trek 
While supposedly present at the Battle of Wolf 359 during Star Trek: The Next Generation, the Borg Queen's first face-to-face encounter with the Federation was during the events of Star Trek: First Contact, when she traveled back in time to stop humanity's First Contact with the Vulcans in 2063. This plan was ultimately thwarted by Captain Jean-Luc Picard (Patrick Stewart) and the crew of the USS Enterprise-E, who helped ensure Zefram Cochrane's (James Cromwell) first warp flight took place. The Queen was seemingly killed by the Enterprise-E crew before they returned to 2373.
However, the Borg Queen was subsequently resurrected and returned in Star Trek: Voyager, where the crew of the USS Voyager did battle with her on multiple occasions while traveling through the Delta Quadrant. Although the Queen worked to destroy Voyager and reclaim their rescued Borg crew member, Seven of Nine (Jeri Ryan), the crew were able to deal some serious blows to the Collective before they left the Delta Quadrant. The most effective was a neurolytic pathogen delivered by the alternate future Admiral Kathryn Janeway (Kate Mulgrew) in Voyager's series finale, "Endgame". The pathogen seemingly killed the Borg Queen again and destroyed the massive transwarp hub she was protecting.
Barring a holodeck cameo in Star Trek: Lower Decks, the next time the Borg Queen appeared in the franchise was in Star Trek: Picard season 2. This version of the Queen (Annie Wersching) was from an alternate timeline created by Q (John de Lancie), who initially warned Picard about the Borg in Star Trek: The Next Generation. After helping the crew of La Sirena travel back in time to stop Q's plans, the alternate Queen assimilated Dr. Agnes Jurati (Alison Pill). Despite her attempts at domination in the 21st century, Agnes was eventually able to convince the Queen to work with her to create a new, more benevolent Borg Collective in the future, one that saved the Federation from an unknown threat in 2401 once the timeline was restored.
However, Star Trek: Picard season 3 revealed that the original Borg Queen had survived Voyager's attack, cannibalizing her remaining drones to sustain herself. When the emaciated Queen learned of Jack Crusher's (Ed Speleers) existence, she allied herself with the rogue Changeling faction led by Vadic (Amanda Plummer) in an effort to assimilate the entire Federation to rebuild her Collective. The Queen lured and assimilated Jack to help her with this plan, turning him into Vox of Borg. Picard and the crew of the USS Enterprise-D once again managed to thwart the Borg Queen's plans and destroyed her once and for all, leaving Jurati's Collective as the only remaining Borg in the galaxy.
Who Played The Borg Queen In Star Trek 
Despite only appearing in a handful of Star Trek projects, the Borg Queen has been portrayed by multiple actors. Alice Krige originated the role in Star Trek: First Contact and reprised it in Star Trek: Voyager's series finale "Endgame", as well as voicing the Queen in Star Trek: Lower Decks and the final two episodes of Star Trek: Picard. Susanna Thompson played the Borg Queen during her other appearances in Voyager besides "Endgame", and the late Annie Wersching portrayed Picard season 2's alternate timeline Queen. Once Agnes Jurati and the Borg Queen merged, Alison Pill took over the role in Picard season 2.
In addition to the main actors who have played the Borg Queen, two other actors helped portray her in Star Trek: Picard. Garth Kemp voiced The Face, an image that the Queen used to communicate with Vadic and her Changelings. Jane Edwina Seymour also played the Borg Queen's physical body during her scenes in the final two episodes of Star Trek: Picard season 3, helping bring the Queen to life along with Alice Krige's voice.
