Borg Queen

Star Trek: First Contact introduced the Borg Queen (played in that movie by Alice Krige). The Borg Queen is the focal point within the Borg collective consciousness and a unique drone within the collective who originates from Species 125 that brings "order to chaos", referring to herself as "we" and "I" interchangeably.

In First Contact, the Borg Queen is seen as apparently present during Picard's former assimilation at the start as flashbacks in Picard's mind, and was believed destroyed on the Borg cube those years earlier, before she directed her attentions to Data in the film. After his capture by her drones, she tried to tempt him with live flesh to comply with her. The Queen was also seemingly destroyed in at least three other instances: during Star Trek: First Contact by Data, most likely for good; "Dark Frontier"; and "Endgame". In the Star Trek: The Experience attraction The Borg Invasion 4-D, the Borg Queen re-appears after Voyager returns to the Alpha Quadrant, but as Admiral Janeway attempts to kill her, she activates a transporter allowing her to survive.

In the Star Trek: Voyager relaunch novels, the Borg Queen isn't a single, irreplaceable entity, but the product of a program called "The Royal Protocol" that shares its name with a Starfleet document outlining requirements when dealing with foreign royalty. This program is used to create a Borg Queen from any female Borg, commanding the technology within her to alter and adapt to the Protocol's specifications. In the relaunch novels, one of the leaders of Starfleet Intelligence gets her hands on "The Royal Protocol" and, with the use of an Emergency Medical Hologram, turns herself into a new kind of Borg Queen who cares about and loves her drones.
