"The Price" but were the principal antagonists in the Voyager episode "False Profits". The Borg race appeared in five of the Star Trek series. Introduced in The Next Generation, they would appear in Deep Space Nine, Voyager, Enterprise, and Picard. Their role in Deep Space Nine was limited to an appearance in the premiere episode to explore Benjamin Sisko's troubled past (his wife having been killed in a major confrontation with the Borg), while their role in the Enterprise episode "Regeneration" served as a 'sequel' to Star Trek: First Contact, as an archaeological expedition discovers the remains of the time-travelling Borg sphere that was destroyed in First Contact and unwittingly reactivate a pair of Borg drones. However, the Borg became a recurring threat on Voyager. One crossover character was the Borg Queen first introduced in the Next Generation feature film Star Trek: First Contact. She would then become a recurring character on Voyager appearing in the two-part episodes "Dark Frontier" and "Unimatrix Zero" and in the series finale "Endgame". These episodes form a narrative thread in which the Borg Queen is battling with Janeway in attempts to re-assimilate Seven of Nine. Only in the final Voyager episode is the Borg Queen played by the same actress who played her in the feature film Star Trek: First Contact, Alice Krige. The magazine Cinefantastique described Krige's appearance as the highlight of this episode. Eventually a new, cloaked form of the Borg Queen appears in Picard, quickly followed by a version more reminiscent of the appearance and personality of the character seen in First Contact and Voyager, in an alternate timeline. Another crossover character is Hugh. First appearing in Star Trek: The Next Generation and then again in Picard. Seven of Nine also crosses over from Voyager to Picard.
