For generations, Trekkies have loved the characters and stories in the Star Trek: The Original Series movies. They also had some of the best antagonists in science fiction. Every villain was not only a problem for James T. Kirk and the crew of the USS Enterprise, but also a challenge to, a distortion of, and a reflection of Starfleet's highest ideals. Let's rank the main bad guys from the TOS movies from first to worst. We'll also talk about what makes each one unique and, at times, very human.
1. Khan Noonien Singh - Star Trek II: The Wrath of Khan (1982)
Khan is still one of the best villains in all of science fiction and Star Trek. Ricardo Montalban's performance brings Khan to life in The Wrath of Khan. Khan is both charming and smart, but he is also dangerously crazy. A lot of Khan's power comes from the fact that his revenge is so complicated: Kirk exiled him to Ceti Alpha V, he lost everything, and his superhuman sense of destiny turned into an obsession. Khan doesn't do bad things without a reason. Instead, his vendetta is personal and has a mix of hurt pride and hatred.
Khan's usage of the Genesis Device is both clever and desperate, which demonstrates that he is a good strategist but also getting more unpredictable. The legendary battle of wits between Kirk and Khan, in which they try to outsmart each other at every move, is quite like the tense chase between the Enterprise and the USS Reliant.
Khan's need for revenge costs both sides considerably, and Spock's death will always be remembered. Khan is a cruel individual because he craves power, is in pain, is proud, and feels he should be the only one in control. Khan's tragic flaw is that he can't move on from the past, no matter what happens.
2. General Chang - Star Trek VI: The Undiscovered Country (1991)
General Chang, the last and most complicated enemy of the TOS movie era, is a wonderfully theatrical antagonist. Portrayed by Christopher Plummer, Chang is a Klingon general who delights in Shakespearean quotations and uses wit as deftly as weaponry. Unlike many of his contemporaries, Chang’s villainy is primarily ideological. He intends to keep the old war between the Federation and the Klingon Empire going at all costs, even after the Praxis explosion nearly crippled the Klingons and sabotaged peace efforts.
Chang is behind one of the most complicated plots in Trek history. He works with elements inside and outside of Starfleet to eliminate Chancellor Gorkon and make Kirk and McCoy look like they did it. Chang is fascinating since he sees Kirk as a worthy opponent; their mutual dislike is mixed with a grudging respect.
3. Commander Kruge - Star Trek III: The Search for Spock (1984)
Christopher Lloyd plays Commander Kruge, who is known for his vicious, animalistic blend of cunning and brutality. Kruge isn't driven by philosophy or his own legacy like Khan or Chang are. He wants the Genesis Device because it gives him power. He sees it as a way to shift the balance of power in the galaxy to the Klingons' advantage.
Kruge is unnerving because he is so unpredictable. He kills his own lover to keep secrets, eliminates subordinates for not doing their jobs, and ends Kirk's son, David Marcus, himself. This act will have long-lasting effects, taking Kirk's only child away and making Kruge a true monster in the eyes of the Enterprise crew.
But Kruge also believes in the warrior's creed, and he enjoys his last fight with Kirk on the disintegrating Genesis Planet. His method of being a villain is crude and immediate, using more muscle than brains, but it works to force Kirk and the crew to do desperate things that will change their lives, like destroying the first Enterprise.
4. V’Ger - Star Trek: The Motion Picture (1979)
The main antagonist in The Motion Picture is more of an existential threat than a villain in the human sense. V’Ger is a sentient machine, a vastly upgraded Voyager probe seeking its creator. It threatens all life on Earth, not out of malice, but out of confusion and a drive for understanding.
V’Ger’s journey forces Kirk, Spock, and the crew to confront the limits of logic, knowledge, and humanity’s place in the cosmos. The confrontation is philosophical rather than combative: V’Ger is lonely, and in its quest to “join with the creator,” it illustrates the danger of unchecked curiosity without compassion or emotion. While V’Ger lacks a personal vendetta or traditional villainous traits, its impact is monumental challenging the very core of Starfleet’s mission to seek out new life.
5. Sybok - Star Trek V: The Final Frontier (1989)
Sybok, Spock's rebellious half-brother, is a very unusual antagonist in the TOS movies. His campaign is not about dominance but spiritual awakening, using his empathic abilities to “free” others from their pain and leading a cult-like following across the galaxy. What makes Sybok intriguing is his conviction and charisma, he is ultimately motivated by love for others and a genuine (if misguided) desire to discover “God.”
He hijacks the Enterprise, not to conquer, but to seek transcendence at Sha Ka Ree, a supposed paradise at the center of the galaxy. Though not conventionally evil, Sybok’s actions pose real danger to Kirk and the crew. He’s a villain by circumstance, not personality, serving as a mirror for the dangers of dogma and the universal quest for answers beyond the self.
7. Captain Klaa - Star Trek V: The Final Frontier (1989)
Klaa is more of a foil than a real enemy in The Final Frontier. He is a Klingon who wants to defeat Kirk for his own fame and glory. His dogged, almost comical pursuit of the Enterprise adds tension, but he doesn't have the depth or philosophical problems of other movie villains.
Klaa's presence shows how restless and competitive Klingons are, yet his threats are never as serious or personal as those made by Khan, Chang, or even Kruge. Still, he serves as a crucial reminder that not every opponent confronts the crew on a vast scale; occasionally, discord arises from adolescent hubris.
Honorable mention: Dr. Soran - Star Trek: Generations (1994)
Rick Berman, Ronald D. Moore, and Brannon Braga made certain the reviled Generations film would go down in history as unquestionably being a Next Generation movie, but the death of Captain Kirk cannot go unchecked since he is the epitome of The Original Series.
Malcolm McDowell plays Soran, a smart but broken scientist who is troubled since the Borg slaughtered his family. Soran wants to get back into the Nexus, where he can be completely happy, and he will do anything to get there, even kill a lot of people. Translation: wiping out, at the very least, the 230 million people living on Veridian IV!
Soran is dangerous since he doesn't care about anything. He thinks that destroying whole star systems is a clinical issue and doesn't care about the needs and lives of others to find his own redemption. Soran is tragic and selfish, and even though he isn't as well-known as other villains, what he does has a huge effect on Kirk's image and the Star Trek universe.
Across six films, The Original Series gave us villains that were rich in personality and philosophy, never just ‘evil’ for its own sake, but adversaries who compelled Kirk and the crew of the Enterprise to question their values, confront tragedy, and occasionally, face their own flaws.
Whether it’s Khan’s undying hatred, Chang’s ideological crusade, or V’Ger’s unfathomable search for meaning, TOS movie villains have helped define science fiction’s greatest adventures. In challenging the future, they forged Starfleet’s finest moments.
