T'Uerell reappears a century later, working with the Klingon Empire to create a particle beam weapon to destroy the Federation. In reality allied with the Borg, T'Uerell allows them to assimilate some of the Klingon Ships, as she has created a prototype of the Borg Sphere and plans to use it to attack the Federation. Resurfacing in the 24th century, chased by Romulan ships after attacking one of their worlds, T'Uerell destroys an nearby uninhabited world to get them off her back, which led to debris from the destroyed planet heading towards inhabited worlds, threatening the lives of millions. Returning to enact her final scheme, T'Uerell has taken over the Borg Collective and wants to [[AssimilationPlot assimilate the entire galaxy]], believing [[TheEvilsOfFreeWill free will to be chaotic and illogical]], and [[ControlFreak wanting to enforce her version of logic and perfection on the galaxy]].

-->--'''Redjac''', "Wolf on the Prowl" [[http://en.memory-alpha.wikia.com/wiki/Wolf_on_the_Prowl comic]]

* Redjac is a non-corporeal being that [[EmotionEater fed on fear and terror]], but enjoyed causing fear just as much as the actual consumption of it. Introduced in season 2 of the original series, in "[[{{Recap/StarTrekS2E14WolfInTheFold}} Wolf in the Fold]]", Redjac had the ability to [[PuppeteerParasite take a humanoid host]], and [[HistoricalRapSheet used these hosts for centuries to commit mass murders]], most notably as UsefulNotes/JackTheRipper. It [[HeManWomanHater targeted women]] because their deaths tended to generate more fear, and was responsible for dozens of deaths across multiple planets, and almost certainly countless more, as it [[HistoricalRapSheet claims to have existed since the dawn of time]]. In the episode, Redjac murders three women and [[FrameUp frames Scotty]] for all of them. When it's discovered, it takes control of the Enterprise's computers and attempts to kill everyone on-board, cackling all the while. While it appears to have been defeated, it reappeared in both the DC and [=WildStorm=] comics. In the DC two-parter, "Wolf on the Prowl" and "Wolf at the Door", it commits several more murders in the body of an Enterprise crewperson, had established itself as the "God of Evil" on a primitive planet, and killed thousands of said planet's inhabitants to give itself power in a last-ditch effort to get revenge on Kirk by destroying the Enterprise. In the [=WildStorm=] comic "Embrace the Wolf", based on the [[Series/StarTrekTheNextGeneration TNG]] universe, it provoked an all-out nuclear war on a peaceful Federation planet, and challenged Data in his Sherlock Holmes persona to save his fellow crew members while Redjac took up its mantle once again as Jack the Ripper. Acting less as a senseless predator and more as a psychotic SerialKiller on a galactic level, Redjac is one of the worst that ''Star Trek'' has to offer.
* The [[HiveQueen Borg Queen]] is one of the most persistent and dangerous foes the Federation has ever faced—having ultimately been [[Recap/StarTrekTheNextGenerationS3E26S4E1TheBestOfBothWorlds responsible for Picard himself previously being forced into the Collective]]. In her [[Film/StarTrekFirstContact first on-screen appearance]], she attacks Earth with a Borg Cube and attends to [[AssimilationPlot assimilate the entire population]] and turn them into Borg drones. When Picard manages to destroy the Cube, the Borg Queen escapes in a sphere and travels back in time to assimilate the Earth in the past—at one point tricking Picard into agreeing to be assimilated again too. After being defeated by Picard, the Borg Queen resurfaces in the Delta Quadrant to menace [[Series/StarTrekVoyager the Voyager crew]]. The Borg Queen kidnaps former Borg drone [[Characters/StarTrekVoyagerSevenOfNine Seven of Nine]] and attempts to [[TheCorrupter corrupt her]], forcing Seven to take part in a Borg invasion of a planet, where the Borg Queen turns the entire population into Borg drones. Later, the Borg Queen discovers that some drones are able to retain their individuality when regenerating. The Borg Queen has drones with this ability disassembled and vivisected. The Borg Queen also begins to destroy Borg vessels that have 1 or 2 drones that are defying her, not caring about [[BadBoss the thousands of other drones who die in the process]]. After a final defeat from Janeway, the Borg Queen [[Series/StarTrekPicard returns decades later to enact her revenge]]. She works with rogue Changelings to infiltrate Starfleet and change the transporter system so that the transporters will secretly transform anyone under 25 into Borg drones. The Borg Queen sends a signal to activate her new drones and they begin to kill everyone who is not a drone. The Borg Queen orders her drones to destroy the Earth and plans to have her drones go across the galaxy and [[OmnicidalManiac kill all other organic life]].

Soong is later informed by Q and the Borg Queen that if he stops [[Characters/StarTrekTheNextGenerationJeanLucPicard Picard]]'s ancestor, astronaut Renée Picard, from completing a space mission, his legacy will be ensured and Earth will become a fascist empire that enslaves alien species and commits genocide against them if they resist. Soong tries to run over Picard with his car, tries to kill Renée with poison, tries to blow up Renée's shuttle with drones, and allows the Borg Queen to turn some mercenaries Soong hired to kill Picard into [[UnwillingRoboticisation proto Borg drones]].
