In a universe where Starfleet personnel are anything but average, possessing expertise ranging from complex physics to intricate diplomacy, it follows that their adversaries must be equally formidable. The intelligence of “Star Trek” villains sets them apart from the typical antagonists in other sci-fi series, making them both engaging and thought-provoking for viewers. Their complex motives challenge audiences to delve deeper into their strategies and intentions.

The most compelling villains in “Star Trek” often serve as dark reflections of the heroes they oppose, heightening the stakes and tension. Even though fans anticipate a triumphant outcome for the protagonists, the presence of a truly intelligent villain keeps them on edge, pondering the possible twists and turns. The franchise boasts a roster of remarkable villains, each as intellectually intriguing as the series itself.

Among these iconic foes is Tolian Soran, portrayed by Malcolm McDowell in “Star Trek: Generations.” As an El-Aurian, like Guinan (played by Whoopi Goldberg), Soran enjoys an extended lifespan, meeting the crew of the USS Enterprise-D as a sage well over 300 years old. His background as a scientist implies a lifetime of accumulated wisdom and innovation, adding layers to his character.

Tolian Soran (Malcolm McDowell) is the primary antagonist of “Star Trek: Generations,” and he’s an El-Aurian, which is the same species as Guinan (Whoopi Goldberg). That affords him a much longer lifespan than most species in the galaxy, and when the USS Enterprise-D crew meets him in the 24th century, he’s at least 300 years old. Given his occupation as a scientist, this suggests that he’s acquired and developed a vast amount of knowledge throughout his lifetime.

Soran’s villainy is more akin to desperation, as he seeks to reenter the Nexus, an ill-defined extra-dimensional realm that destroys starships. Anyone caught inside the Nexus experiences a timeless personal utopia, making Soran’s desire to return understandable. Still, that doesn’t excuse his actions, which include the purposeful destruction of one star and the desire to destroy a second. This would alter the Nexus’ path through the galaxy, allowing him to return.

Soran succeeds, but thanks to the Nexus’ displacement from spacetime, Captains Picard (Patrick Stewart) and Kirk (William Shatner) return to stop him before he can finish his goal. Soran kills Kirk but is ultimately defeated by the captains’ combined efforts. It’s unclear how smart Soran truly was, but his intellect was likely in excess of human-defined levels of genius. Still, this didn’t save him from two of the franchise’s most beloved captains when they came together to thwart his plan.

The first season of “Star Trek: The Next Generation” culminated in the revelation of a massive conspiracy. It took several episodes to arrive at the conclusion, which came about as senior members of Starfleet were found to behave oddly by several captains. In the episodes, Captain Picard and Commander Riker (Jonathan Frakes) use deception to gain entry to the highest levels of the conspiracy, where they learn that the top-level officers in Starfleet are controlled by parasitic beings.

These aliens aren’t explained beyond an accounting of their discovery in the 2360s in some unexplored region of the galaxy. When Picard and Riker follow some of these parasites to their mother creature, it’s found to be a larger version that resides within the chest cavity of Commander Dexter Remmick (Robert Schenkkan) after they blast him with their phasers. They destroy the monster, save Starfleet, and wrap things up to move on to the next adventure.

What’s not explored about the parasitic beings is their intelligence, which is odd because they’re remarkably smart for what have humorously been dubbed “butt bugs.” Not only can a single parasite take over the body and mind of a host, but they have also worked across vast distances to coordinate a massive conspiracy to take over the entire Federation. The mother creature was likely the most intelligent, as it appeared to be directing the actions of its brood, and given the scope of its plan, the species is one of the most intelligent villains in “The Next Generation.”

In “Star Trek: Picard’s” second season, Q (John de Lancie) transports the main characters back in time, where Picard meets Dr. Adam Soong (Brent Spiner). He is the 21st-century ancestor of the Soong dynasty, most of whom are played by Spiner. Soong is an engineer and geneticist whose experiments resulted in the creation of several clones he called his “daughters.” These all came about via somatic nuclear cell transfer, making them artificially created, which posed genetic problems.

When Q proposes a means of saving Soon’s longest-surviving daughter, Kore (Isa Briones), he becomes an enemy to Picard and his friends. In every way possible, Soong steps in and upsets Picard’s plans, pushing against his efforts to stop Soong, as his actions result in the alteration of history for the worse. Soong is ruthless in his endeavor, and he employs his considerable intellect and monetary resources to do everything he possibly can to impede Picard. He nearly succeeds before the season comes to an end.

Soong is human, but he’s also a genius who managed to create a human through his genetic research alone. When he ultimately fails in his plan, he turns to another line of research, Project Khan, showing that he is the one who is ultimately responsible for the creation of all genetically modified humans who went on to dominate the planet during the Eugenics Wars. Being the “father” of modern eugenics certainly demonstrates Soong’s intellect while highlighting his lack of morality.

When the Borg first appear in “The Next Generation,” they represent a force that Starfleet is incapable of defeating. They’re the cybernetic equivalent of space locusts, devouring everything in their path, only instead of eating, they assimilate whole species. This makes the Borg one of “Star Trek’s” most disturbing alien species, but it also makes them one of the smartest. For every species the Borg assimilates, their knowledge increases exponentially, and they’ve assimilated a lot of them.

The Borg operate via a hive mind with a single Borg Queen as its leader, and this villain is one of the deadliest and most intelligent in the franchise. There is only one Borg Queen at any given time, and when one is destroyed, another takes her place. Still, they’re all the same being, as each new queen is merely a host for the single entity. The Borg Queen is several centuries old, possibly much older, and she retains the knowledge of every being she’s assimilated.

The Borg Collective had, at its height, a population likely in the trillions, and the Borg Queen had the knowledge of them all. Essentially, she represents the combined intelligence and knowledge of entire species. She’s spread across the cosmos, where drones acquire an unending supply of new Borg for the Collective. It’s impossible to measure the Borg Queen’s intelligence, as there’s no metric for the amount of knowledge inside her head, but it’s certainly immense.

Starfleet’s covert intelligence organization, Section 31, used a threat assessment system called Control that used artificial intelligence to perform its tasks. In “Star Trek: Discovery,” the system manages to prevent a war through its machinations, but after the conflict is over, Starfleet hands over its decision-making to Control. Before long, Control turns on its creators and kills everyone in Section 31 headquarters by shutting off all life support, using holograms of the deceased crew to obfuscate its duplicity, giving Control more time to develop its plan.

The USS Discovery finds and destroys the HQ in an attempt to stop Control, but it survives. The crew surmises that Control has been infected by an AI system from the 28th century, and it has become nefarious and far more intelligent than it should be. It’s also sentient and planning the destruction of all life in the galaxy. This is not necessarily an unattainable goal, spurring the Discovery into action.

Ultimately, the Enterprise and Discovery stop Control, so the latter vessel flees into the 32nd century to ensure it never acquires the data it sought. Because Control is a sentient AI, its level of intelligence is only limited by its memory and storage capacities, which are immense. Control isn’t the only world-dominating evil AI system in “Star Trek,” but the scope of its operations and its plans to end all life in the galaxy elevate it beyond the likes of M-5, Nomad, and the others.

While “Star Trek: The Motion Picture” isn’t the best film in the franchise, it did introduce an interesting villain in V’Ger. The initially enigmatic being causes widespread destruction and is unlike anything previously encountered by the Federation or others in the galaxy. It appears in the form of a massive cloud capable of emitting extraordinary levels of energy amounting to that of thousands of starships, and it destroys Klingon K’t’inga-class battle cruisers with ease.

At this point in the film, V’Ger is referred to only as “the intruder,” a malevolent being capable of anything… and it’s headed towards Earth, leading the crew of the USS Enterprise to confront it. When they do, they ultimately discover that the intruder calls itself V’Ger, and is, in fact, the Voyager 6 probe launched by NASA in the 20th century. It’s revealed that the probe fell into a black hole and was transported across the galaxy to a world of machine entities. They built a vessel around the center of the probe and sent it back to its creator, which took centuries.

Along the way, V’Ger became self-aware and acquired untold knowledge as it evolved from a relatively simple probe into a massive entity. It seeks only to return to its creator, so V’Ger isn’t a villain in the traditional sense, but that doesn’t make it any less dangerous. In terms of intellect, V’Ger is a constantly evolving, sentient AI and a living machine. Ultimately, it transcends physical existence, becoming a being of pure energy.

After a frustrating holodeck experience with Lieutenant Commander Data (Spiner), Lieutenant Geordi (LeVar Burton) asks the Enterprise computer to program a character who can beat Data. The computer complies, rewriting the Professor James Moriarty (Daniel Davis) holodeck character, making him sentient. Not only is Moriarty now self-aware, but he learns incredibly fast. He threatens a hostage by taking over various holodeck systems, including the safety protocols, which are often worthless in “Star Trek’s” best holodeck episodes.

Because the computer designed Moriarty to be able to beat Data, his intelligence rivals that of the android. That’s significant in and of itself, but in learning of his sentience, Moriarty has something Data lacks: emotions. This ultimately proves to be his undoing when he’s inadvertently brought back online by Lieutenant Barclay (Dwight Schultz). Moriarty learns that nothing has been done to allow him to leave the holodeck, so he takes over the ship and threatens it with destruction.

He does this in an attempt to save not only his own life, but also the life of Countess Regina Bartholomew (Stephanie Beacham), another holodeck character and Moriarty’s companion. Picard gets the upper hand and traps Moriarty and the Countess inside a storage device where they can live out their digital lives in oblivious bliss. He returns via the security system for the Daystrom Station in “Picard,” and because of the nature of Moriarty’s inception, his intellect is, at the very least, on par with Data’s.

While Data is an inquisitive, ethical android, he’s not the only being created by Dr. Noonien Soong. As seen in “The Next Generation,” Data’s “brother,” Lore, was created first. But Lore’s emotions get the better of him, pushing Dr. Soong to disassemble him. Dr. Soong then builds Data, who lacks emotions but craves them as he desires to be more human. Lore couldn’t be any more different, as he not only possesses emotions, but he also loathes all biological life. He teams up with the Crystalline Entity to wipe out all life on Omicron Theta, making him a particularly dastardly villain.

Lore’s emotional programming becomes unstable, breeding a malevolence he uses to achieve his desires. When the Borg are corrupted by the introduction of individuality, Lore takes advantage, controlling the rogue population of Borg for his own purposes. He experiments on them and uses Data’s stolen emotional chip to also control Data after disabling his ethical subroutines. It’s during this encounter that Data finally stops Lore, shooting him with a phaser before disassembling him.

Eventually, Lore is transferred to the Daystrom Station for study. His personality attempts to overtake Data’s within a golem designed to create one being out of the two brothers, Dr. Soong, and the Soong-type androids B-4 and Lal. Ultimately, Data defeats his brother, absorbing him into his own being. Lore is as intelligent as Data, but he lets his emotions drive his actions, which often results in his downfall. He’s incredibly advanced, and when you look at Data’s intellect, it’s clear that Lore is one of “Star Trek’s” most intelligent villains.

Of all “Star Trek’s” corporeal villains, Khan Noonien Singh (Ricardo Montalban) is the most intelligent and ruthless. While he’s not a sentient android, Khan is a genetically-engineered human augment, and his intellect is considerably greater than any other human in the galaxy. This was true during his time in the 20th and 21st centuries, and remains true during the 23rd century when he’s awakened from stasis by the crew of the USS Enterprise.

He attempts to take over the ship and nearly succeeds, but is ultimately marooned on Ceti Alpha V by Captain Kirk. Years later, in “Star Trek II: The Wrath of Khan,” the augmented despot returns after the USS Reliant considers a world they mistakenly believe is Ceti Alpha VI for the Genesis Device. Khan takes over the ship and sets out on a “Moby Dick” style campaign of vengeance against now-Admiral Kirk, and he nearly succeeds in killing him. In the end, Khan is defeated, but his actions result in the death of Spock (Leonard Nimoy).

Khan is one of the scariest villains throughout sci-fi, not because he’s a frightening bug monster, but because his drive, intellect, and relentless nature make him a nearly unstoppable force. He’s the perfect adversary for Captain Kirk, who shares in his determination, if not his intellectual capacity. Khan is a genius with physical and mental enhancements that neither Kirk nor anyone else can match, making him one of the most dangerous villains in the franchise.

When “The Next Generation ” premiered, it introduced the franchise’s most powerful and intelligent enemy in Q. As a member of the Q Continuum, Q possesses what seem to mortals like godlike powers. He can alter reality with a snap of his fingers and travel to any time and place he desires, and he is only limited by his imagination. In his first appearance, Q puts the crew of the Enterprise-D on trial for humanity, and the trial is not concluded at the end of the episode.

Instead, he continuously interrupts and upsets Picard’s plans, taking a personal interest in him. All indications of Q from the start are that he’s an omnipotent being, but this is proven untrue as time passes. In “Picard,” Q’s powers begin to wane, and his final act is one of kindness for his old friend/nemesis. Still, up to that point, it seemed as if Q was nearly omniscient and capable of anything. That’s how he’s presented throughout much of the franchise, making him both an unstoppable force and an immovable object.

Picard’s wit and stoicism help guide his actions in their encounters, and while Q is near-infinitely intelligent, he’s not omniscient. That said, he’s as close to omniscient as any “Star Trek” character could be, making him the clear winner in terms of intelligent villains. That said, he’s more of a trickster than a straight-up villain, depending on who he’s tormenting at any given moment.
