Warning: SPOILERS for Star Trek: Picard Season 3 Finale – "The Last Generation"Special guest star Alice Krige provided the voice, but a new actress played the Borg Queen in Star Trek: Picard season 3's finale, "The Last Generation." The Borg Queen was revealed as the ultimate villain in Star Trek: Picard season 3. The Borg joined forces with the Changelings to assimilate Starfleet, while the Queen fulfilled Jack Crusher's (Ed Speleers) destiny to become Vox of Borg. But Admiral Jean-Luc Picard (Patrick Stewart) and the crew of the USS Enterprise-D rescued Jack and dealt the Borg their greatest defeat.
The Borg Queen was introduced in Star Trek: First Contact, where she was played by Alice Krige. As the leader of the Borg Collective, the Queen was retroactively behind the assimilation of Captain Picard into Locutus of Borg. In spite of multiple defeats, the Queen returned several times and was played by different actresses, including Susanna Thompson in Star Trek: Voyager and Annie Wersching in Star Trek: Picard season 2. However, as the original Borg Queen, Krige is the best-known and most popular actress in the role. Thankfully, Krige returned to lend her voice to Star Trek: Picard season 3 while another actress physically embodied the Borg's ruler.
