Main Cast (in order of billing)

    Captain James Tiberius Kirk
"I don’t believe in the no-win scenario."
Played by: William Shatner
Dubbed in French by: Yvon Thiboutot (TOS), Sady Rebbot (Star Trek I to VI), Denis Savignat (Generations)

"'All I ask is a tall ship, and a star to steer her by.' You could feel the wind at your back in those days, the sound of the sea beneath you. And even if you take away the wind and the water, it's still the same... The ship is yours, you can feel her. And the stars are still there, Bones."
Kirk, "The Ultimate Computer"

The Captain. James Tiberius Kirk leads his ship, the Enterprise, through the adventure of the week—hostile cultures, supercomputers, places which look suspiciously like Earth, time-travel shenanigans. A very talented and level-headed officer, Kirk always took his duty to Starfleet deeply seriously and his main concern in any crisis was always the safety of his ship and crew. He was notorious for his many brief romances, some of which ended tragically, but mostly they failed because he named the Enterprise herself as the woman in his life. Although he took the dangers to his crew very seriously, he also maintained a light-hearted attitude and bantered with the other two members of his Power Trio frequently.

Although boldly going and playing by his own rules worked out pretty well during the height of his career, the movies Deconstructed his legend by showing how high the cost of such cavalier actions could be.

  • A.I. Is a Crapshoot: Kirk went up against malevolent computers so often that it became something of a Running Gag in the fandom.
  • Ambiguously Jewish / Ambiguously Christian:
    • Captain Kirk's famous line to the alien impersonating the Greek god Apollo in "Who Mourns for Adonais?" is this:
      Kirk: Mankind has no need for gods. We find the one quite adequate.
    • An idea with some popularity in the fandom is that he's really Jewish, since both William Shatner and Chris Pine are Jewish. As fan-theories go, this is not too far-fetched, since Christianity is essentially an offshoot of Judaism. That said, Kirk has no uniquely Jewish behaviors to speak of.
    • In another episode, Kirk and crew come upon a planet dominated by a Roman Empire but with 20th century technology, where a persecuted, pacifist new religion worships a sun god. At the end of the episode, Lieutenant Uhura discovers that this new religion does not worship the Sun but the Son, clearly referencing Jesus. Kirk even considers remaining at the planet for a number of years just so they can "watch it happen all over again."
  • Anti-Hero: Sixties sex symbol or not, Kirk stumbled into Classical Anti-Hero in The Wrath of Khan where his mid-life crisis wears heavy upon him and some poor choices cost the lives of many recruits, and later Knight in Sour Armor in The Undiscovered Country.
  • Badass Normal: Kirk is a good tactician who leagues of more powerful aliens respect, whose exploits include beating a bio-engineered superman with his bare fists. Did we mention he's a non-powered human?
  • Bold Explorer: Though it was just his job, Kirk's boldness makes him an iconic version of the trope.
  • Boldly Coming: The Trope Codifier through Pop-Cultural Osmosis, although it's nowhere near as omnipresent as you might believe. Over 79 episodes, the number of alien women Kirk definitely sleeps with is... four. Only one of thosenote  was a straightforward example of sex for enjoyment, and none of them were green (that was Pike, and she wasn't even really green. The green woman Kirk met was a mental patient who tried to seduce him, to his immense discomfort).
  • Bunny-Ears Lawyer: The things Kirk got away with...
  • But for Me, It Was Tuesday: His trip to the Mirror Universe. While there, Kirk single-handedly talks Mirror Spock into instigating an uprising against the Terran Empire. We're meant to think they'll eventually find their way to a Federation-like alliance, but in Deep Space 9 we find that Kirk's machinations left mankind ripe for an asskicking by a combined Klingon / Cardassian / Bajoran alliance, after which humans are enslaved. The top dogs of the Mirror Universe are on constant look-out for anyone coming over from the other universe to interfere again, redesigning their tech to make damn sure it wouldn't, and Kirk's name is legendary among them. For Kirk, and Starfleet, the Mirror universe incident was just a weirder-than-average day at the office.
  • The Captain: Kirk is the Trope Maker.
  • The Chains of Commanding: Often has to choose between the Girl of the Week and his duty, and otherwise gets caught between The Spock and The McCoy (i.e., logic vs emotion) a lot.
  • The Charmer: Kirk is quite the ladies' man, although not the out-of-control horndog he is often misremembered as.
  • Chivalrous Pervert: May very well be the anti-Bond. Except for a very few times where he used his charm to further a greater purpose, Kirk almost always developed sincere feelings for the Girl of the Week, and was just as often badly hurt when they were separated or she met with an unfortunate end... which happened often.
  • Companion Cube: Kirk's strongest love in the TV series is for the Enterprise herself; this may vary between Happily Married and The Masochism Tango. The movies have this become overshadowed by loyalty to his True Companions, culminating with his painful decision to self-destruct the original 1701 in Star Trek III.
    • A Running Gag in the movies is Kirk's loving relationship with his chair. He glumly sits in the rickety captain's chair aboard the Enterprise-A, declaring that it's just not the same. Generations repeated this gag on-board the Enterprise-B, this time complete with Male Gaze.
  • Court-Martialed: "Court Martial": Kirk gets put on trial for (seemingly) causing the death of a crew member through negligence.
  • Dark and Troubled Past: At some point before he got to command, Kirk was witness to the massacre on Tarsus IV, where thousands were killed in an attempt to hold off starvation that came to naught when the supply ships arrivednote . During his time on the Farragut, Kirk was the sole survivor of an attack by a vampiric cloud creature.
  • Determinator: When Kirk makes up his mind to do something, especially if the lives of his crew are at stake, no force in the universe can keep him down.
  • Did You Just Punch Out Cthulhu?: A specialty of Kirk's.
  • The Dreaded:
    • The name James Kirk is spoken with great annoyance by the Temporal Investigations department. Seventeen different violations will do that for you.
    Agent Lucsly: The man was a menace.
    • Back in his academy days, Cadet Kirk was the fear of the underclassmen.
    Gary Mitchell: "Watch out for Cadet Kirk! In his class, you either sink or swim."
  • Dropped a Bridge on Him: His death in Generations is the Trope Namer.
  • Embarrassing Middle Name: "Tiberius."
  • Ethical Slut: Although he romances many women, he's not a cad or a pervert.
  • Fan of the Past: He embraced the culture and history of his homeland, especially western lore and the life of his hero Abraham Lincoln. Recognizing the document mirrored on the planet Omega IV, he could recite the preamble of the US Constitution from memory. His extensive knowledge of his ancestral background served him well on numerous occasions. In travels to Earth's past, or on planets mirroring Earth's development, Kirk was able to function and pass himself off as a native of the time or culture with (more or less) ease
  • Farm Boy: Kirk was born and raised on a farm in Iowa.
  • Former Teen Rebel: Inverted. Unlike his alternate universe counterpart, Cadet Kirk was something of a humorless swot as an underclassman, only later developing into the Military Maverick we see in the series.
  • Four-Star Badass: In the movies. And everyone knows it. Though as a Rear Admiral, technically he was only a Two-Star Badass. Until he gets demoted at the end of Star Trek IV. However, this is also largely subverted. Kirk's moments of badassery as an admiral are actually while he's in direct command of a starship and he's shown to be apathetic and uninterested towards his admiralty duties, such as when he almost immediately cuts the inspection of the Enterprise short in The Wrath of Khan.
  • Four-Temperament Ensemble: Kirk is the Choleric.
  • Freudian Trio: Kirk is the Ego to Spock's Superego and McCoy's Id.
  • Genocide Survivor: In "The Conscience of the King", Kirk is stated to be a survivor of a genocide on the planet Tarsus IV, where the Governor ordered thousands of citizens killed to ensure the rest could survive, using eugenics to decide who lived and died. Oddly, Kirk's status as a survivor of a genocide is rarely touched on elsewhere in the series.
  • Gold-Colored Superiority: As The Captain, he wears a gold shirt.
  • Gunboat Diplomacy: One of his favorite diplomatic techniques seems to be threatening to blow up a planet that doesn't do what he wants. Somehow he gets away with this. He's Kirk. He even gives orbital bombardment a go as a persuading tool (with phasers on stun... sometimes). Partially justified by the fact he was trained as a soldier, not a diplomat.
  • Has a Type: Of the five women Kirk had long-term relationships with before the series, four out of five were blondes and/or scientists. (The exceptions being Janice Lester, a brunette scientist, and Areel Shaw from "Court Martial", a blonde Starfleet JAG officer.)
  • Heartbroken Badass: Let's see...with the losses of Edith Keeler, his brother Sam and his sister-in-law, his wife Miramanee and their unborn child, Rayna Kapec, his first BFF Gary Mitchell, his true BFF Spock, his son David, and the Enterprise herself, it's amazing that there's still anything approaching an intact heart by the time he retires.
  • He Knows Too Much: Kirk is one of nine surviving eyewitnesses who can identify Kodos the Executioner, the man who ordered the deaths of four thousand people on colony planet Tarsus IV. Kodos's daughter Lenore tries to kill him by hiding an overloading phaser in his quarters. By the end of the episode, Kirk is one of only two surviving witnesses, since she succeeded in killing the other seven.
  • The Hero: He is clearly the protagonist of the show (and the cause of some off-screen drama).
  • Heroic Willpower: In "Dagger of the Mind," one of the bad guys notes that he hasn't given in when subjected to a force that reduced one of their scientists to screaming.
  • Hollywood Mid-Life Crisis: In most of the films, he suffers from a bad case of this. Starting with Star Trek: The Motion Picture, in which he struggles with the question of whether he is too young to be an Admiral or too old to be The Captain; this leads him to take back command of the Enterprise as soon as a major threat to Earth is spotted, shamelessly ousting its current (younger) Captain. Subsequent films would have him agonizing, sometimes to the point of Wangst, over his age, career, life in general, and missed opportunities. Notably, he is the only character who seems to suffer from this, to the occasional frustration of Bones and Spock.
  • Honor Before Reason: In "Arena" and "Spectre of the Gun."
  • I Can Still Fight!: Kirk doesn't like being shut up in medbay at all, much to McCoy's consternation.
  • Improbable Age: Minor example In-Universe. Background material states that, at 30-ish, he is the youngest man yet to command a first-rate Starfleet ship, a record that wasn't broken until the first year of TNG, when Tryla Scott (played by Afro-American actress Ursaline Bryant) is promoted to captain of the USS Renegade in her late twenties (albeit thanks to a burst of parasitic infiltrators).note 
    • In the season 2 episode "The Deadly Years", Kirk is stated to be 34 years old. He had been Captain of the Enterprise for two years at that point, making him 32 at the time he got the promotion - or to put it another way, just a decade out of the Academy, an average of one promotion every two years.note  Had he continued at that pace, he would have made full Admiral by age 40.
    • Although Kirk's rise to the Captaincy was exceptionally rapid, it's clear that he's obviously an extreme outlier with regard to the average quality of Starfleet officers (even in TOS, most other Starship Captains we meet wind up dead or go insane). Contrast his reboot counterpart, who is field-promoted to Captain from Cadet before graduating from the Academy, which might generously be described as a bit farfetched.
    • Curiously, his Mirror Universe counterpart, who is considerably less competent than the Prime Kirk, only reached the rank of Captain through plundered alien technology allowing him to remotely eliminate all of his superiors without putting himself in danger of retaliation.
  • Improbable Weapon User: In hand-to-hand combat, he will sometimes grab whatever object is nearby, regardless of what it is. Twice, he has used pillows.
  • Insane Admiral: Drifts perilously close to this early in Star Trek: The Motion Picture, especially when butting heads with the Enterprise's new Captain. He gets over it to some extent, but his later actions lead to a "demotion" that puts him back in the captain's chair, which is exactly where he wants to be and resolves the problem.
  • The Kirk: He's the Trope Namer, obviously. Whenever presented with a hard dilemma, he almost always tries to find the Third Option that allows for a morally acceptable solution without sacrificing any more crew or victims.
  • Killed Off for Real: In Star Trek: Generations. Let's just say they...Dropped a Bridge on Him.
  • Knight in Sour Armor: In Star Trek VI: The Undiscovered Country. He thinks the peace negotiations with the Klingons are a bad idea and will end poorly, but he still does everything he can to make sure they succeed. He even gets angry with Spock after Spock reveals he felt the need to vouch for Kirk's dedication to duty for the mission.
  • Large Ham: He's played by William Shatner, after all.
  • The Leader: Famously of the Levelheaded type. Come crisis or moral questions, Kirk's main approach was to let his officers have their say on the matter at hand and then try to find a way to successfully combine the various strengths of their advice into an effective solution. He also treated his responsibility to his crew with unwavering seriousness, often sticking his own neck out so they wouldn't have to.
  • Legendary in the Sequel: Kirk is depicted as the Captain, against which all of his 24th-century successors are judged (well, eventually. Early TNG episodes treated Kirk's era like it was shrouded in myth, if they acknowledged it at all — even though Dr. McCoy shows up in the pilot episode). Of course, with The Next Generation being the first Star Trek TV series since the original, using an entirely new crew, this was intentional by the producers, who wanted the series to stand on its own. This even extends to the reboot continuity, where a bunch of Romulan space miners living over a century after his heyday immediately recognize James T. Kirk by name as having been Starfleet's greatest Captain.
  • Living Legend: Even though the original series depicts his first command, it's clear that he's already becoming one of these. The movies take this trope and run with it.
  • Logic Bomb: Known for this in just about any episode featuring A.I. Is a Crapshoot... and then some.
  • Married to the Job: No matter what, his main commitment is always first and foremost to the safety of the Enterprise and her crew. This sense of duty in him is so overpowering he doesn't even need an antidote to a love potion.
  • Memetic Badass: In-Universe example. Kirk serves as one for all of Starfleet. When given with the chance of meeting him, Picard and Sisko both positively Squee!. Considering that both Picard and Sisko are also examples of this within the Trekverse, that says something.
  • The Men First: Being A Father to His Men, Kirk is always insistent on keeping them safe if possible. On a number of occasionsnote , he has wanted to pull a Heroic Sacrifice (or even tried to do so) to ensure the well-being of his crew, and torturing them is generally a better strategy than torturing him.
  • Mr. Fanservice: That uniform shirt of his will tear open at the touch of a twig. This was not actually intentional; it's just that the tailoring budget for the original show was less than impressive.
  • Must Have Caffeine: Nothing from a super-powerful alien threatening to blow up his ship to a crew member vanishing into thin air on an inexplicably abandoned planet can come between Kirk and his cup of coffee. (When an infestation of tribbles do, then It's Personal!)
    Kirk: (regarding a cup of tribbles) This was my chicken sandwich and coffee! I want these things off the ship, I don't care if it takes every man we've got!
  • My God, What Have I Done?: His reaction to sacrificing the Enterprise in The Search for Spock. Understandable, given that for Kirk, it's the equivalent of sacrificing a lover all over again. Good thing Bones was there to remind him:
    McCoy: What you had to do. Turn death into a fighting chance to live.
  • My Greatest Failure: Kirk came to see his banishment of Khan as this, as not only did it leave him and his crew off-guard for Khan's Roaring Rampage of Revenge after the unexpected destruction of his world and the death of his wife, but it ended up initially coming at the expense of his best friend's life, something he continued to feel guilty of by The Search for Spock.
  • Not So Different: From the Romulan Commander in "Balance of Terror."
  • Officer and a Gentleman: In addition to judo-throwing aliens and romancing Green Skinned Space Babes, he finds time to be well-versed in classical literature and offer aid to space-borne refugees.
  • Once Done, Never Forgotten: Kirk is positively notorious in Starfleet for his violations of the Prime Directive. However lost in the shuffle is that in most cases, Kirk arrives on the scene only after someone has already interfered, and he's now in a position where he must fix or mitigate the damage, or prevent others from interfering.
  • Papa Wolf: Kirk is A Father to His Men who makes a habit of punching out any entity, super-powered or not, that messes with anyone in front of him. Hurting his people (or actual children) causes him much Angst and more anger. Do the math on whether messing with anyone under him is a good idea.
  • Rank Up: He gets promoted to rear admiral sometime prior to Star Trek: The Motion Picture. However, at the end of Star Trek IV: The Voyage Home, Starfleet busts him back down to captain for stealing the Enterprise in defiance of orders in The Search for Spock.
  • Rude Hero, Nice Sidekick: Inverted, Captain Kirk is a charming Officer and a Gentleman. By contrast, his first officer, Spock, is more tactless and ruthlessly pragmatic. The fact that he's also The Stoic when he does these things probably doesn't do his image any favors.
  • Screw the Rules, I'm Doing What's Right!: Kirk does this quite a bit. Spock reminds him of "our prime directive of non-interference" and he rationalizes a way around it. Hell, if he were anyone else other than James T. Kirk, he'd have been toast long ago, but he is supposed to have unusually broad powers to make decisions affecting his crew, alien societies and new worlds. Many times he doesn't violate it and instead he or the bridge crew find a clever way to solve the problem without doing so. In fact more often than not, Kirk is in the position of having to undo damaged caused by others.
  • Shirtless Scene: It's not quite to the level of Walking Shirtless Scene, but Kirk appears shirtless a lot in the original TV show. Mostly famously, it's caused by Clothing Damage during action sequences, but he also tends to just lounge around his quarters without a shirt and such.
  • Smart People Play Chess: He's Spock's opponent of choice in chess games and is quite cunning, as a lot of foes have found out, to their regret.
  • Sudden Name Change: In the second pilot episode, Gary Mitchell, possessed of near-omnipotent alien powers, fights Kirk and creates an open grave with a tombstone reading "James R. Kirk." This would normally be a minor matter, but given how many times Kirk later introduces himself as "James T. Kirk," it's actually quite jarring.
  • Survivor Guilt: In "Conscience of a King", Kirk is revealed to have been one of the people whom Kodos deemed worthy of his eugenics program, which would further explain Kirk's hatred of him.
  • Talking the Monster to Death: Far more often than he gets credit for these days. Kirk is good at talking monsters to death (AKA fast talking his way out of a jam). Since he routinely runs into Sufficiently Advanced Aliens who cannot be defeated with firepower, it's an important skill.
  • To Be Lawful or Good: One of the most frequent moral dilemmas faced by Kirk in quite a few stories. To his credit, he usually manages to come up with a way to actually be both lawful and good, but when his back is truly against the metaphorical wall, he will slightly lean towards the good option and be willing to bend the rules, though he never takes such a decision lightly.
  • True Companions: with Spock and McCoy.
  • Ultimate Job Security: Later crews even lampshade that Kirk shouldn't have been able to get away with so much. However, the times when he's reckless or rebellious have been exaggerated in popular culture's perception of the character; ordinarily, he's a pretty law-abiding guy. Furthermore, Starfleet looking the other way regarding his more wild exploits makes sense insofar as the Enterprise is continually getting mixed up in situations where one wrong decision could result in the destruction of humanity at the hands of alien forces, and Kirk is the only captain proven to have a talent for continually making the right call in those circumstances. Organizational discipline is one thing, but species survival Drumpf it.
  • Verbal Tic: His peculiar speaking style is perhaps the most famous (and certainly the most frequently-parodied) thing about him. A combination of Gratuitous Iambic Pentameter and Punctuated! For! Emphasis!, along with seemingly random, inappropriately-placed pauses, then followed by delivering the rest of his line in a rushed, breathless pace, as if he has to make up for time lost from taking the pause.note 
    • In "Get a Life!" Shatner claims that it's a holdover from his D-list theatre days, when it was the only thing that kept the audience awake. Since his daughter thinks Kevin Pollack does a better Kirk than him, he also asks Pollack to help him punch up his Kirk.
  • War Hero: Captain Kirk is openly stated to have been decorated many times for valor. Kirk doesn't talk about his awards or display them, preferring to keep them locked away in his quarters.
  • Worthy Opponent: Klingons, in particular, recognized Kirk as this. The legendary Kor, frustrated by Organian interference that made battle against Kirk impossible, wistfully surmised, "it would have been glorious" in 2267. Captain Klaa believed defeating Kirk would make him the greatest warrior in the galaxy in 2287. General Chang reveled in his attack on Kirk at the Battle of Khitomer, until he lost his advantage.

    Lieutenant Commander (later Commander) Spock
"The needs of the many outweigh the needs of the few, or the one."
Played by: Leonard Nimoy
Dubbed in French by: Régis Dubos (TOS), Jacques Harden (Star Trek: the Motion Picture), Robert Party (Star Trek II, IV, V and VI), Michel Bardinet (Star Trek III)
Dubbed in Latin American Spanish by: José Lavat (TNG)

"'Fascinating' is a word I use for the unexpected. In this case, I should think 'interesting' would suffice."
Spock, "The Squire of Gothos"

Kirk's Number One and Science Officer. Spock was half-Human, half-Vulcan, and chose to completely embrace the latter aspect of his heritage; this caused him to clash frequently with Dr. McCoy. Spock was supremely analytical and would describe many things as "fascinating;" he was the go-to man for unusual solutions...or ruthlessly pragmatic ones. He would, occasionally, let slip his more human feelings, but regarded any comparison with humanity to be insulting during the show's run.

Despite the stark contrast in their personalities, Spock and Jim were very good friends (so much so that they inspired Slash Fic in 60's and 70's fanzines). The character became so iconic that Nimoy put out an autobiography titled I Am Not Spock, although he later embraced the fanbase, writing another autobiography titled I Am Spock. He reprised the character in Star Trek: The Next Generation and Star Trek (2009) and its sequel Star Trek Into Darkness.

  • Ambadassador: He later became an ambadassor for Vulcan and he's prettyhandy in a fight.
  • Ambiguously Jewish: Many fans think that Spock is Jewish on his human mother's side as Leonard Nimoy is Jewish, not to mention that Winona Ryder (who played Spock's mom, Amanda Grayson, in the 2009 reboot) is Jewish as well. (Jane Wyatt, who created the role back in '68, was Catholic.) On a related note, Nimoy adapted the famous Vulcan hand salute and its greetings "Peace and long life" and "Live long and prosper" from Jewish religious tradition. In addition, Celia Lovsky, who played the matriarch T'Pau in "Amok Time", was Jewish and had fled Nazi-occupied Austria with her husband, Peter Lorre. A running gag in some fan clubs was that Vulcans were Jewish. See Jewish Themes in Star Trek by Rabbi Gershom.
  • Arranged Marriage: Betrothed by his family as a child. His intended bride had other ideas, and didn't mind sacrificing Kirk for them...
  • Back from the Dead: In the third movie he is resurrected by an ancient Vulcan ritual.
  • Badass Bookworm: Spock can (and does) use his vast knowledge in conjunction with fighting whatever enemy they're facing.
  • Beware the Nice Ones: Spock is a vegetarian and a Technical Pacifist, but if you ever remove his emotional control or threaten Kirk, you're in trouble.
  • Bizarre Alien Biology: Principally his green blood and the fact that his heart is where a human's liver would be. The latter enables him to survive being shot in the back with a flintlock rifle in "A Private Little War."
  • Bizarre Alien Senses: Vulcans are natural telepaths, and they can use their mental powers to read minds, share thoughts, sense the emotions of and communicate with any alien being with a mind. Assuming they find a suitable receptacle, they can even preserve their consciousness after death.
  • Blue Blood: No, has nothing to do with his Alien Blood. It's not explicitly stated, but his father, Sarek, is a prestigious astrophysicist and Federation Ambassador (whose reputation among his notoriously xenophobic people was able to withstand his marriage to an "out-worlder"), and T'Pau, one of the most powerful people on Vulcan, officiates at (what should have been) his wedding. He also notes that the large estate where the ceremony takes place has been in his family for over two thousand years.
  • Blue Is Heroic: Spock's blue uniform represents his coolness and rationality.
  • Boomerang Bigot: Spock is half-human, but most of the time, he solely embraces his Vulcan heritage and is scornful of human ways. This was later explained via D.C. Fontana's Backstory due to his rocky relationship with his father and the Fantastic Racism he experienced whilst growing up on Vulcan. He mellowed in his later years.
  • But Not Too Foreign: He's half-human; while he usually acts fully Vulcan, his human side surfaces fairly often.
  • Captain Ersatz: Spock's personality is an exaggeration of Roddenberry's former boss, LAPD Chief William H. Parker.
  • Catchphrase: "Fascinating," accompanied, of course, by a Fascinating Eyebrow.
    "Fascinating" got started because Nimoy asked director Joseph Sargent to help him in playing a non-emotional character while filming "The Corbomite Maneuver". Sargent told him "Be different. Be the scientist. Be detached. See it as something that’s a curiosity rather than a threat." Nimoy half-whispered the line as a reaction to the first sight of Balok's huge ship, and "a big chunk of the character was born right there."
  • Character Development: During the series proper, Spock utterly refuses to show emotion, and makes no secret of his dislike for humans. During The Motion Picture, his mind-meld with V'Ger causes a profound shift in his viewpoint - logic alone is cold and barren. By the time of Wrath of Khan, he's mellowed out considerably, even going as far to wish Kirk "happy birthday", and in The Undiscovered Country, he no longer sees logic as the be-all-and-end-all. By the events of Star Trek (2009), he's mellowed to the point where he tells his alternate younger self to sometimes "put aside logic" and "do what feels right".
  • Characterization Marches On: In early episodes, he wasn't quite yet the emotionless Vulcan we all know him as and was even seen to smile a few times. In a scene from "The Cage" where the aliens snatch two female crew members, Spock shouts, "The women!" in a very emotional manner. The end of "The Enemy Within", where after Kirk's Evil Twin attempts to rape Yeoman Rand and Spock leeringly teases Rand about the duplicate's "interesting qualities," is surely the most misogynistic moment in the entire Trek canon. Spock hadn't been given his emotionless personality because that was meant to be part of Number One's character. The network was not comfortable with the idea of a cold, unemotional woman (let alone one with a measure of command authority), so the character was scrapped and the trait transferred to Spock. Leonard Nimoy has admitted that in early episodes he was mainly playing Spock as a military officer. In " The Corbomite Maneuver", there's a scene where the Enterprise is seized by a gigantic and apparently hostile vessel and Spock merely says "fascinating" (for the first time). Nimoy has cited this as the moment the character really "clicked" for him, although it still took a few more episodes for Spock to fully settle into his stoic characterization. Also, a line "Where No Man Has Gone Before" has Spock refer (with amusement) to irritation as "one of your Earth emotions," indicating he's biologically incapable of emotion, at least as humans understand it. This is most decidedly not the case.
  • Chick Magnet: Kirk may be the one who goes down in history as a lady's man, but that doesn't mean Spock didn't get several gals looking his way, hoping to crack that icy Vulcan exterior. Pretty much all of them are doomed to failure.
  • The Comically Serious: Given his lack of emotions and frequent misunderstandings, he's usually assigned with some funny scenes.
  • Court-Martialed: In "The Menagerie," Spock gets put on trial for commandeering the Enterprise and taking it to a forbidden planet.
  • The Creon: Spock is this, almost to the letter. He only takes command of the Enterprise once Kirk has been Kicked Upstairs, and gives it back almost immediately when the opportunity arises. And, being already a captain and in command of the Enterprise, Spock never gets his own commission; he keeps his position as first officer under Kirk for several more movies! He said many times, "I do not wish to command." Surprisingly, Spock's mirror-universe counterpart is exactly the same on this and even explicitly states his reasons (in "Mirror, Mirror")note 
    • Subordinate Excuse: Spock's friendship with Kirk may be an explanation for why Spock continues to serve as Kirk's first officer even after he is promoted to Captain himself.
  • Dark and Troubled Past: During "Journey to Babel", his mother mentions Spock was frequently bullied as a child, something "Yesteryear" expands upon.
  • Deadpan Snarker: Apparently, there is nothing illogical about scathing sarcasm. Despite his claims to be above human pettiness, Spock frequently makes sarcastic quips or the "Really?" face.
  • Defrosting Ice King: Even with the crew's massive Power of Friendship skills, it took Spock years to decide that emotions were not such a bad thing.
  • Deuteragonist: A natural result of his popularity with fans; originally, the show was intended as having plots about "Kirk and X," where "X" would be a different character each week; many of the early first-season episodes follow this formula, but gradually "X = Spock" became more common.
  • Fantastic Racism: A victim of this trope, as well as a mild subscriber mainly towards humans (at least initially).
  • Forgets to Eat: Occasionally.
    • While never shown, in "Amok Time," McCoy uses the fact that Spock hasn't eaten for three days in an attempt to convince Kirk that something is wrong, and Kirk dismisses it as simply being Spock in one of his contemplative phases.
    • Another example is "The Paradise Syndrome," where Spock hardly eats for weeks while studying the obelisk.
  • Four-Temperament Ensemble: Spock is the Melancholic.
  • Freudian Trio: Spock is the Superego to Kirk's Ego and McCoy's Id.
  • Friendless Background: As demonstrated in the animated series, Spock never had any friends growing up because of the Half-Breed Discrimination on his planet.
  • Gentleman and a Scholar: While most definitely a scholar (being highly knowledegable on the cultures of other species), the gentleman portion varies and is often downplayed.
  • Good Is Not Nice: He's rude, tactless, and completely cold-hearted, but he always has the best interests of the ship and crew in mind.
  • Half-Breed Angst: When Spock was a boy, he was teased for being half-human and half-Vulcan (an alien species that suppresses emotions) and didn't know which species to live the lifestyle of. Even though he chose the Vulcan way, his own father rejected him for choosing Starfleet over the Vulcan Science Academy and Vulcan society continues to ostracize him.
  • Half-Human Hybrid: Spock completely embraces the non-human side of himself. As a child, the local children rejected him because of his human heritage.
  • Hidden Depths: He'll never let it show, but several times it's hinted he's sitting on the occasional mass of self-loathing. Just for example, the end of "This Side of Paradise".
    Spock: We all have our own purgatories. Mine can be no worse than any others.
  • Hidden Heart of Gold: Spock makes a point of keeping it hidden and gets very embarrassed when it's uncovered.
  • Human Mom Non Human Dad: His mother is a human named Amanda. His dad is Sarek, a Vulcan.
  • Insult Backfire:
    McCoy: Spock, you are the most cold-blooded man I've ever known.
    Spock: Why, thank you, Doctor.
  • Interclass Friendship: Kirk and Spock started their strong friendship when Kirk was captain and Spock still held a lieutenant commander's rank. This downplayed example disappears when Spock becomes first officer, but the second season replaces it with another, much more dramatic, gap — "Amok Time" and "Journey to Babel" state that Spock comes from an important clan and that his father serves as the Vulcan ambassador. Kirk comes from Iowa and had no apparent special status before coming to Starfleet.
  • Jerk with a Heart of Gold: Spock is cold, rude, and tactless, but always has the crew’s best interests at heart and is clearly far less emotionless and cold-hearted then he appears to be.
  • Killed Off for Real: Dies offscreen of natural causes (and at the age of 162) in Star Trek Beyond, due to Leonard Nimoy's own death.
  • Kindhearted Cat Lover: He's very fond of cats.
  • Leitmotif: Gerald Fried's score for "Amok Time" (which also introduced the famous "Star Trek fight music") featured a recurring motif for Spock, a quite expressive, sorrowful tune played adagio with the main melody line provided by a bass guitarnote  - to represent Spock's deeply felt, but repressed, emotional state. The show's frequent reuse of previously recorded music allowed this piece to become a de facto leitmotif for Spock as it was often used in his big "emotional" scenes (for lack of a better word) throughout the second and third seasons.
  • Living Legend: Invoked in "Amok Time" when T'Pring informs Spock that he has become a legend among the Vulcans, and that she has no desire to become the consort of a legend. His status only grows through his efforts to achieve a lasting peace with the Klingons, and his subsequent ambassadorial career. In the later shows, he is depicted as Legendary in the Sequel even though he is technically still alive throughout the franchise (including into the reboot continuity).
  • Ludicrous Precision: Will often give time estimates down to the second and can complete large exponential multiplications in his head.
  • Mayfly–December Friendship: At two hundred years old, a Vulcan might still have a number of years left. Humans can live a few decades past one hundred, but it's clearly old for them, meaning Spock is doomed to outlive all his human friends.
  • Mind Rape: In hindsight, trying to mind meld with the vast, living computer of V'Ger was not Spock's most sensible move ever. He screams in pain from the sheer sensory overload, and comes out the other side seeing that logic is no longer the be-all and end-all.
  • Minored In Ass Kicking: Especially when you realize that Vulcans are extremely strong compared to humans.
  • Number Two: Spock is this as well as the science officer. note .
  • Only One Name: Spock's full name is never officially revealed. As he stated to one of his girlfriends in the series, "You couldn't pronounce it."
  • Parenthetical Swearing: Often when delivering a Stealth Insult.
  • Rank Up: At some point prior to the movies, he acheived the rank of Commander.
  • Red Oni, Blue Oni: Spock is the Blue to McCoy's Red.
  • Rubber-Forehead Aliens: Though in his case, he is a rubber-eared alien and half human.
  • Running Gag: His "inability to lie," despite repeatedly proving otherwise.
  • Sarcastic Devotee: There are few people who are as loyal to Kirk as Spock is, but that doesn't protect the captain from his snarky wit.
  • Smart People Play Chess: ''Three-dimensional'' chess, that is.
  • The Smart Guy: Genius-level intellect, impossibly knowledgable and scientific. Being half-Vulcan helps.
  • The Spock: He's the Trope Namer, natch. In a crisis, the solutions he offers are usually rational in service to the overall mission, if a little cold-blooded at times.
  • The Stoic
    • Not So Stoic: Although in most of the cases when he show emotions, it is usually a result of either mind control, drugs, or side effects from strange phenomenons, but he does have some moments where it genuinely comes from himself, most notably the scene from "Amok Time" where he realizes that Kirk wasn't Killed Off for Real, and greets him with a loud and happy "JIM!"
      • He gets another moment in Star Trek VI: The Undiscovered Country when Valeris, his protege, is revealed to be the conspiracy's mole aboard the Enterprise. She has a phaser drawn on him, and when she refuses to shoot, he slaps it out of her hand with a clear look of anger on his face. Then, in one of the most Squick-filled scenes of the entire franchise, he proceeds to Mind Rape her right on the bridge in front of God and everybody. Pushing this man's Berserk Button is nigh-impossible, but if you do, you're in for a world of hurt. (So is he — his expression as he invades her mind looks like he's being forced to eat razor blades.)
  • Straw Vulcan: At times.
  • Super Strength: His Vulcan heritage makes him three times stronger than a human. Roddenberry specified that Vulcan is a large planet with a heavier gravity. (Most Vulcans we see are played by tall, slim actors rather than Heavyworlder types, so there might be other factors.)
  • Takes Ten to Hold: In Operation: Annihilate!, Spock goes ballistic. It takes three Enterprise crewmen to subdue him due to his Vulcan side's Super Strength.
  • Tall, Dark, and Snarky: Spock is one of the taller members of the cast, considered good-looking in and out of universe, and one of the series' greatest Deadpan Snarkers.
  • True Companions: with Kirk and McCoy.
  • Token Non-Human: He's the only regular in the cast who is visibly nonhuman. (The animated series averted this since there was no make-up budget in the way.)
  • Troll: Despite his outwardly serious demeanor, Spock often finds ways to subtly mock or annoy people who he has disdain for or wants to needle for whatever reason, often so carefully that they may not realize he's doing it.
  • Verbal Tic: His endless permutations of the word "logic," and his unfailing ability to fit them into sentences, border on this.
  • Vitriolic Best Buds: With McCoy. That Spock considers him a close friend is established beyond all doubt in "Amok Time," when he invites him, along with Kirk, down to Vulcan to witness a ceremony which is deeply private and personal to Vulcans. McCoy,in complete sincerity tells Spock that he would be honored.
  • The Worf Effect: Any enemy that can hold Spock in a fight is deemed a formidable adversary.
  • You Called Me "X"; It Must Be Serious: He only calls Kirk "Jim" in two circumstances - when for some reason he's acting seriously out of character, or they're in absolutely dire straits.

    Doctor (Lieutenant Commander) Leonard Horatio "Bones" McCoy
Played by: DeForest Kelley
Dubbed in French by: Michel Georges (TOS), François Marié (Star Trek I to V), Jean-Pierre Delage (Star Trek VI)

"I signed aboard this ship to practice medicine, not to have my atoms scattered back and forth across space by this gadget."
McCoy, "Space Seed"

The third member of the Power Trio. Nicknamed "Bones" by Kirk, McCoy was a highly competent doctor who wasn't entirely comfortable with deep space and always brought a more emotional and moral component to the philosophical debates. He clashed frequently, and colorfully, with Spock, as he found Spock's rejection of emotion to be absurd; however, the two men did genuinely respect each other. Despite his "down-home country doctor" routine, McCoy could and did carry moments of badassery frequently.

Despite a very wild appearance — including a full beard — in the first one, McCoy remained largely the same in the movies: a cantankerous but kind-hearted medical professional.

  • Ambiguously Christian: He frequently swears in the name of God, or Heaven. He explicitly mentions Jesus in Star Trek VI: The Undiscovered Country, one of only two times in the history of the entire franchise he is mentioned by namenote . When he is about to kill the salt vampire in "The Man Trap", he asks the Lord to forgive him. He remarks in "This Side of Paradise" how their rejection of the spores is the second time Man's been thrown out of Paradisenote . His staunch pacifism is certainly consistent with the tradition of Christian pacifism, and many conscientious objectors have served as medical personnel. However, the character never came out and professed a belief in the divinity of Christ (or in any other religion).
  • Badass Pacifist: He's a doctor and takes that very seriously. However, that doesn't stop him from doing extremely dangerous things to save lives. Circumstances sometimes force him to show that he is a decent shot and somewhat competent brawler, but he is hardly a willing Combat Medic, both disgust with violence and unashamed fear always extremely apparent on his face. Possibly best seen in "Space Seed," where he doesn't flinch at Khan holding a knife to his throat and even gives advice on the best way to kill him from their current position.
  • Berserk Button: Don't recommend pragmatism and coolheadedness over compassion during a crisis.
  • Blue Is Heroic: McCoy's blue uniform represents his gentleness and kindness. See also Innocent Blue Eyes.
  • Catchphrase: Two:
  • Chivalrous Pervert: He's notable for being more open about his skirt-chasing than Kirk...and less successful at it.
  • Cool Old Guy: Subverted; he's middle-aged, but he's still quite awesome.
  • Combat Pragmatist: McCoy is especially fond of hitting an enemy (or even a reluctant friend) with a hypospray to render them unconscious/simulate a disease/etc. in order to get the upper hand. In "Amok Time," he does this without being an actual participant in the fight in order to save Kirk's life and Spock's career.
  • Deadpan Snarker: He specializes in snarky comments. "This Side of Paradise" has a couple gems.
    McCoy: [after Kirk informs a man that he will be taken from his planet with or without his cooperation] Should I get the butterfly net?
  • Determined Doctor: Where Scotty wouldn't roll over and die on keeping the ship together, this man refuses to just let his patients die if he has any means to save them.
  • Dr. Jerk: While he's a Jerk with a Heart of Gold, his cantankerous reminders of his actual occupation qualify for this trope. In "Friday's Child," he persuades an obstinate, haughty patient to let him ease her slapping her in the face. Justified in that the woman in question was a Capellan, a Proud Warrior Race that regards a show of force as a sign of respect and honesty, and that McCoy was an expert on this species, having been part of the first contact team that discovered them years earlier. Given that the woman later gave birth and named the child after McCoy, it worked as well as intended:
    Kirk: Never seen that in a medical book.
    McCoy: It's in mine from now on.
    • Especially in "This Side of Paradise," when he's under the influence of Applied Phlebotinum that makes him more irritable.
      Sandoval: We don't need you, not as a doctor.
      Bones: Oh, no? Would you like to see just how fast I can put you in a hospital?
  • First-Name Basis: With Kirk, although in Kirk's case, it's McCoy's nickname, "Bones," never his first name, "Leonard." (Kirk does call him "Leonard" exactly once, in "Friday's Child", but it's context-specific.)
  • Four-Temperament Ensemble: McCoy is the Sanguine.
  • Freudian Trio: McCoy is the Id to Kirk's Ego and Spock's Superego.
  • Frontier Doctor: Dr. McCoy is perhaps Trek's outstanding example of a final frontier doctor —resourceful in the face of alien ailments, preferring simple homespun methods when possible, but cantankerous, eccentric, and not entirely happy with his lot (he fled to space on the heels of a divorce). Star Trek was pretty much the original Space Western, after all, and actor DeForest Kelley had an extensive background in westerns.
  • Good Is Not Nice: He's not hesitant about expressing his dislike for people or his refusal to suffer fools, but he is most often the one who suggests doing the right thing.
  • Good Old Ways: He both enforces and subverts this trope. He's rabidly in favor of fighting the dehumanizing effects of too much technology (especially the transporter) in favor of enjoying "the simple things in life," and yet sees "primitive 20th-century medicine" as just above trepanation, leeches, and blood-letting in its barbarity, preferring the "high-tech approach" to healing. In general, he embraces the positive, constructive aspects of technological progress rather than the destructive or dehumanizing ones.
  • Grumpy Bear: McCoy is constantly grumbling about space travel, supercomputers, Spock, unruly patients, etc, etc.
  • Grumpy Old Man: He becomes this in the movies. His brief cameo in TNG has him even older and grumpier.
  • The Heart: He's a deeply ethical man underneath his cantankerous exterior and always brings the moral side to a discussion.
  • He's Dead, Jim: He's the Trope Namer.
  • Honor Before Reason: McCoy believes in doing the right thing no matter what, and he will proudly admit it.
  • Hospital Hottie: According to Jadzia Dax, one of her previous hosts discovered he has the "hands of a surgeon."
  • Hypocritical Heartwarming: McCoy is always trying to get an emotional rise out of Spock, but in the episode "Plato's Stepchildren," McCoy jumps to Spock's defense when powerful aliens force him to cry and to laugh. And in other episodes, he's usually the first to jump to Spock's defense any time anyone attacks or insults him, possibly because his issues with Spock are more of a giant angry moral debate while other people tend to operate out of pure racism.
  • I'm a Doctor, Not a Placeholder: He's the Trope Namer.
  • Innocent Blue Eyes: McCoy has DeForest Kelley's bright, shining baby blues. He's probably the kindest, most compassionate character of the entire Trek franchise.
  • In-Series Nickname: "Bones" is actually short for "saw-bones," an archaic term for a surgeon.note  It was originally intended as the nickname of Dr. Boyce from "The Cage," but was never used in that episode, making it available for McCoy.
  • Knight in Sour Armor: He's grumpy, sarcastic, and has little respect for authority (with the exception of Kirk), but when the chips are down, you can always count on him to do the right thing.
  • The Medic: He's even able to treat a silicon-based life-form.
  • The McCoy: He's the Trope Namer. In a crisis, his proposed solutions usually involve trying to do the right thing in the moment and standing on principle no matter the long-term costs.
  • More Hero Than Thou: In "The Empath," when aliens offer Kirk the choice of sacrificing McCoy or Spock, McCoy takes out Kirk with drugs. Spock is glad; since this leaves him in command, he can make the sacrifice himself. McCoy proceeds to drug him as well and sacrifice himself.
  • Promotion to Opening Titles: At the beginning of the second season.
  • Rank Up: By the time of Star Trek: The Next Generation, he's an Admiral. His promotion to Captain, while never seen on screen, has been stated in non-canon publications as having taken place sometime in the late 2290s. Several published works have also indicated that he later served as the head of Starfleet Medical School and as the Starfleet Medical Surgeon General. The reference manual Star Trek: The Next Generation Officer's Manual states that he eventually became Chief of Starfleet Medical and held a special rank known as "branch admiral".
  • Red Oni, Blue Oni: He's the Red to Spock's Blue.
  • Resignations Not Accepted: At the beginning of the first movie, McCoy has retired to private practice, and is called back into service against his protests on Kirk's request.
  • Sarcastic Devotee / Sour Supporter:
    • He will follow Kirk into the pits of Hell and back, but he'll grumble about it first.
    • Similarly, if Spock is in trouble he'll strive to help him, just don't expect him to hold back on a few jibes whilst he does.
  • Southern-Fried Genius: One of the most respected doctors in the Federation—straight out of Georgia.
  • Strawman Emotional: At times.
  • Super Doc: He can be nothing else such as when he successfully treated the Mother Horta, a silicon based lifeform whose physiology he is not only completely unfamiliar with, but he didn't even believe such a lifeform even existed until that very moment.
    McCoy: By golly, Jim, I'm beginning to think I can cure a rainy day!
  • Tall, Dark, and Snarky: Not as tall as Spock, but plenty dark-haired and snarky.
  • True Companions: With Kirk and Spock.
  • Vitriolic Best Buds: With Spock. They argue constantly but if anyone other than him attacks or criticizes Spock (and that includes Kirk), he will always rush to his defense.
  • The Watson: Despite serving on Starfleet's flagship, McCoy is routinely unfamiliar with various technical aspects of the ship or other technology he encounters. (He is an excellent doctor, however, which makes up for it.)
  • Wrote the Book: According to STV, he wrote a book called Comparative Alien Physiology, which is required reading at Starfleet Medical. It's apparently the Grays Anatomy of aliens.
  • You Called Me "X"; It Must Be Serious: In contrast to Spock, it's when Bones calls Kirk "Captain" and not "Jim" that you know he's not messing around.

    Lieutenant Commander Montgomery "Scotty" Scott
Played by: James Doohan
Dubbed in French by: Julien Bessette (TOS), Georges Aubert (Movies)

"I cannae change the laws of physics! I've got to have thirty minutes!"
Scotty, "The Naked Time"

Chief Engineer of the Enterprise. Scotty's most frequent job was to solve a seemingly-impossible crisis with the engine or transporters (or whatever piece of Starfleet technology was making trouble that week), protesting all the way before either hitting on a creative solution or sweating it through. He was also Scottish and had many sterotypical Scottish traits, such as a love of good whisky and namedropping haggis. Scotty was firmly established as the ship's third-in-command behind Kirk and Spock, and seeing as those two were always members of the landing party, he took the conn with surprising regularity. Though he was sometimes used for comic relief, it's worth noting that Scotty was extremely badass whenever he was the ranking officer on the bridge and kept it safe from interfering aliens or Starfleet's many half-crazed admirals.

Scotty's role in the films was still the Chief Engineer, but he was relegated to the comic relief role more often. He also appeared in an episode of The Next Generation.

  • Berserk Button: He's a very calm, polite, and peaceful man...unless you call the Enterprise a piece of garbage. Then he'll punch you in the face regardless of the cost.
  • Big Damn Heroes: In "Friday's Child," Kirk, Spock, and McCoy are unarmed and surrounded by a superior Klingon force.
    Kirk: [to Spock] Too bad the cavalry doesn't come over the hill anymore. [cue Scotty beaming down with a large force of Redshirts to save the day]
  • Butt-Monkey: Sometimes, when he was left in charge of the Enterprise.
  • The Captain: He gets promoted to the rank of captain in The Search for Spock, which puts him on equal terms with both Kirk and Spock. It's no small feat, either. He's one of the very few non-command division people to achieve the rank and the promotion is given in recognition of his engineering skills. He never pulls it on anyone, however.
  • Captain Ethnic: Or in this case, Lieutenant-Commander Ethnic. In case the accent, taste for whisky, and the occasional wearing of traditional Scottish clothes and playing of bagpipes don't clue you in, there is also the surname. Lampooned in the I'm Sorry, I'll Read That Again parody:
    Uhura (Jo Kendall): Captain, our Scottish chief engineer Scott"Scotty" for shortfrom Scotland has something terrible to tell you.
    Scott (Graeme Garden): [incomprehensible Scots English gibberish]
    Kirk (Tim Brooke-Taylor): Yes, that was terrible, wasn't it?
  • Companion Cube: If Kirk saw the Enterprise as a demanding wife, Scotty saw the ship, particularly her engines, as no less than children ("My bairns! My poor bairns!").
  • A Day in the Limelight: "Wolf In The Fold," "The Trouble With Tribbles," "By Any Other Name," and "The Lights of Zetar."
  • The Engineer: His primary duty.
  • Father Neptune: Though as he is Recycled In Space, perhaps he would be Father Jove or Father Apollo, but you get the idea.
  • Formerly Fit: He's fairly portly in most of his post-TOS appearances. Of course, since it's a live-action show it's a case of Real Life Writes the Plot.
  • Four-Temperament Ensemble: Scotty is the Phlegmatic.
  • Gadgeteer Genius: Can MacGyver just about anything on his own, but particularly shines teamed with Spock. The two of them could turn the most obscure theory into a way to save the day.
  • Genius Bruiser: Pretty handy with both his fists and his mind.
  • Leitmotif: More an example of a Bootstrapped Leitmotif. A piece called "A Matter of Pride" was composed by Jerry Fielding for "The Trouble with Tribbles" to underscore the scene where Scotty admits he started the bar fight with the Klingons. It was then reused for "By Any Other Name" in the scene where Scotty drinks Tomar under the table. It was never used again, but because of its exclusive association with two of Scotty's greatest character scenes, it is sometimes remembered as "Scotty's Theme" among fans.
  • Rank Up: In Star Trek III: The Search for Spock, he gets promoted to Captain and reassigned to the USS Excelsior as Captain of Engineering during the ship's early test runs.
  • Scotty Time: He's the Trope Namer.
  • Unwitting Instigator of Doom: Twice from the same action. His sending the tribbles home with the Captain Koloth apparently resulted in an ecological disaster for the Klingon Empire, which in turn caused the Klingons to hunt down the tribble homeworld and obliterate it, rendering them extinct. At least for a century, or so. The DS9 crew undid the second part by accident.
  • Wrote the Book: According to the TNG episode "Relics", he wrote some of the Starfleet engineering regulations that are still in use. Hence, he knows when it's safe to ignore them.

    Lieutenant Nyota Uhura
Played by: Nichelle Nichols
Dubbed in French by: Arlette Sanders (TOS), Laure Moutassamy (Star Trek: the Motion Picture, III, IV, V and VI), Jane Val (Star Trek II)

Uhura: Mr. Spock, I haven't done anything like this in years. If it isn't done just right, I could blow the entire communications system. It's very delicate work, sir.
Spock: I can think of no one better equipped to handle it, Miss Uhura. Please, proceed.
— "Who Mourns for Adonais?"

Uhura was Enterprise's communications officer and, according to Gene Roddenberry, was fourth in line of command behind Mr. Scott (something flatly contradicted in the series, where Sulu and even DeSalle took command ahead of her). Unfortunately, her character was vastly underutilized during the series' run, although the times she was allowed to do more than be the ship's phone operator, she was pretty good at whatever she was doing. Her role was somewhat expanded after the first season and she did get to take the captain's chair in the animated series.

Off-screen, Nichols was subjected to racist harassment and resigned when she learned that the studio executives had been withholding her fan mail. A conversation with Martin Luther King Jr. convinced her to stay; he told her that the idea of a black woman being equal to whites was something vitally important for children to see, as a role model or as an example of what should be. Both Mae Jemison (America's first black female astronaut) and Whoopi Goldberg have cited her as an influence, along with many others. Nichols worked with NASA to recruit women and minorities into the astronaut corps.

  • '60s Hair: Wore a pixie cut before sporting a bouffant in the later seasons.
  • Action Girl: In "Mirror, Mirror" and "The Gamesters of Triskelion."
  • Bridge Bunny: To Nichols' frustration. She did have a few episodes where she was in the landing party, but for the vast majority of the show, she was confined to her station.
    • For a long time, in interviews Nichols would answer the question, "What is your favorite episode of the series" with "Any episode that got me off the bridge."
  • Catchphrase: "Hailing frequencies open." She says this seven times in her debut appearance, "The Corbomite Maneuver", including five times in a row. It's no wonder she complains about hearing the word "frequency" too many times in "The Man Trap".
  • Communications Officer: One of the most famous examples.
  • A Day in the Limelight: "Mirror, Mirror" and "The Trouble With Tribbles." Star Trek: The Animated Series added "The Lorelei Signal".
  • Meaningful Name: Uhura is derived from Uhuru, which means "freedom" (which carried a strong Reality Subtext in the 1960s), while Nyota means "star."
  • Not Even Bothering with the Accent: She is African and her first language is Swahili, yet she sounds American. Justified in that she is a linguist.
  • Rank Up: At some point prior to Star Trek II: The Wrath of Khan, she made Commander.
  • Ret-Canon: Her first name, Nyota, was used in the non-canon novels for decades before finally being made official. Very early Trek guides suggest that Penda was considered a possibility by the fans. Parodied in the 2009 film when Uhura refuses to tell Kirk her first name until the end of the movie.
  • Sassy Black Woman: Generally averted - Uhura is dignified and professional (in keeping with the Sidney Poitier school of black portrayals at the time). She does have her moments however:
    • When Sulu is under the influence of the polywater in "The Naked Time" and says "I'll rescue you, fair maiden", she famously quips "Sorry, neither" in response.
    • She's unfailingly respectful of her superiors on-duty but is not above gentle ribbing when off-duty. She serenades Spock with "Oh, on the Starship Enterprise" in "Charlie X" and when Kirk comments she didn't waste her time beaming down to Space Station K-7 when he authorized shore leave in "The Trouble with Tribbles", she remarks "And how often do I get shore leave?". Neither Kirk nor Spock react as if this is anything out of the ordinary.
    • In Star Trek III: The Search for Spock she is very happy to give "Mr. Adventure", who just moments before had called her over-the-hill and said her career was winding down, a piece of her mind (and the business end of her phaser). As Bones comments: "I'm glad she's on our side."
  • Ship Tease:
    • She appears to show an interest in Spock in a few episodes. (Yes, long before the reboot.) According to Nichols, this was largely her own idea, that it was a one-sided relationship.
    • By the later movies, she seems to be in a casual relationship with Scotty.
    • She shares a kiss with Kirk in "Plato's Stepchildren," although given that it was under alien Mind Control and both were rather traumatized; if anything, it may be Ship Sinking.
  • Silk Hiding Steel: Uhura may be a non-combatant most of the time, but as noted above, she is quite the Action Girl when necessary. In particular, "Mirror, Mirror" and "The Gamesters of Triskelion" show that Uhura can kick someone's ass when necessary, and the animated series shows she's not afraid to take command and take the initiative when needed.
  • Tomboy and Girly Girl: Her tomboy to Christine's girly girl.
  • Twofer Token Minority: She's an African and a woman.

    Lieutenant Hikaru Sulu
Played by: George Takei
Dubbed in French by: Daniel Roussel (TOS), Tola Koukoui (Star Trek I to V), Patrick Guillemin (Star Trek VI)

"We're using hand phasers to heat the rocks. One phaser quit on us, three still operating. Any possibility of getting us back aboard before the skiing season opens down here? "
Sulu, the one with the alien unicorn dog

The helmsman, thankfully living in a time before bridge consoles were Made of Explodium. Sulu was an affable and level-headed officer, a staple of bridge drama and away missions. He worked well with other members of a crew and sometimes shared his hobbies: botany, antiquing, and fencing (although the last one was not exactly in a clear state of mind). When Chekov was added to the cast, they formed a Those Two Guys dynamic.

Although he has a Japanese first name, his surname is deliberately ambiguous; it is the name of a sea that borders several Asian countries note . Like Uhura, Sulu was significant for being a non-stereotypical portrayal of an Asian man. In the fourth film, we learn that he was born in San Francisco.note 

  • Absentee Actor: Missing for much of the second season because George Takei was filming The Green Berets.
  • The Ace: Like Kirk, an experienced and capable multi-talented officer who went on to have a distinguished career as a captain of his own. Unlike Kirk, who never made time for a family and whose hobbies seem limited to drinking, womanizing, and the occasional manly camping trip/rock climbing expedition, Sulu also managed to have a happy marriage, a beautiful daughter who followed in his footsteps, and cultivated a variety of interests outside his career, including fencing, botany, and tea.
  • Brainwashed and Crazy: Again, "The Naked Time."
  • Canon Immigrant: His now-canon first name, Hikaru, was given to him in the non-canon novels by Vonda N. McIntyre, before officially being made his name in Star Trek VI: The Undiscovered Country. Very early Star Trek guides suggest that Walter was considered as a possible first name during the show itself, but never officially used.
  • Cultured Badass: Very knowledgeable in many subjects, such as botany, and when he gets infected and runs amok with a fencing foil in "The Naked Time", he even scares Kirk.
  • A Day in the Limelight: "The Naked Time" and "Mirror, Mirror."
  • Deadpan Snarker: Sulu is prone to making pithy commentary on the events of the episode.
  • Evil Is Hammy: Every Mirror Universe character was hammy, but Takei was a particularly rich, dripping slice.
  • Fan of the Past: He's a history buff and a competent fencer. Overlaps with Ace Pilot in the movies when, upon a simple inspection of the controls, he flies a 20th-century helicopter competently enough to perform cargo-lifting duties.
  • Fleeting Passionate Hobbies: Including fencing ("The Naked Time") and botany ("The Man Trap"). In fact, in "The Naked Time," Kevin Riley Lampshades it.
  • Generation Xerox: In Generations, we meet his daughter Demora, who is (where else?) at the helm of the Enterprise-B.
  • Genius Bruiser: Just happens to be an expert in botany, swordsmanship, French history, and flying ancient aircraft.
  • Good Scars, Evil Scars: His Mirror Universe counterpart has a big nasty scar on his face.
  • Gun Nut: Overlapping with Fan of the Past, in "Shore Leave," he's thrilled to find an ancient revolver. An animated series episode expanded this to Sulu having expertise with weaponry across the board.
  • Inscrutable Oriental: Deliberately inverted per the series bible. Sulu's most prominent trait was probably his sense of humor and enthusiasm for hobbies that never seemed to last. This got an in-joke in the animated series when he claimed, with a wink, you had to be "inscrutable" to fight the way he did—and Kirk replied "you're the most scrutable man I know."note 
  • Katanas Are Just Better: Averted in "The Naked Time." Sulu was originally supposed to go on his rampage with a samurai sword, but at Takei's request to do something less stereotypical, it was switched to an epee.
  • Nice Guy: Consistently friendly and level-headed. Subtly demonstrated in "Day of the Dove", when an Energy Being triggers a Hate Plague on the Enterprise; Sulu is the only one who never seems to act out or show anger (even Spock is seething with Tranquil Fury).
  • Rank Up: The last we see him, he's captain of the USS Excelsior.
  • The Reliable One: He's quite competent at a variety of tasks, and very level-headed compared to characters like Chekov or Scotty. He's also fiercely loyal to his crewmates, to the point of disobeying Starfleet orders and potentially causing a serious diplomatic incident just to rescue them.
  • Screw the Rules, I'm Doing What's Right!: In the mostly-embarrassing "Turnabout Intruder," Sulu gets a good moment when he says he'll flatly refuse any order to execute a fellow officer.
  • Shirtless Scene: In "The Naked Time."
  • Those Two Guys: With Chekov.
  • Took a Level in Badass: As Captain of the Excelsior in Star Trek VI.
  • Universal Driver's License:

    Ensign Pavel Andreievich Chekov
Played by: Walter Koenig
Dubbed in French by: André Montmorency (TOS), Thierry Bourdon (Star Trek: the Motion Picture), Vincent Violette (Star Trek II, V and VI), Nicolas Brémont (Star Trek III and IV), Gilbert Levy (Generations)

"Of course, Doctor. The Garden of Eden was just outside Moscow. A very nice place. Must've made Adam and Eve very sad to leave."
Chekov, "The Apple"

The ship's navigator from Season 2 onwards. Chekov had a tendency to refer to Glorious Mother Russia and claim that any human advancement, be it technological or cultural, originated there. He also had terrible luck and frequently ran foul of whatever physical or psychological menace the ship was facing that week, mainly because Walter Koenig had an excellent capacity for screaming. Aside from that, he and Sulu were good friends and would frequently banter about the action.

Chekov is, by far, the most junior of the regular bridge officers, but the writers justified his presence by having him act as the relief science officer whenever Spock was busy or incapacitated. In fact, Chekov would often abandon his navigation console in order to take up the science scanner if Spock had to step away, even at warp or in the middle of a battle. In Star Trek III: The Search for Spock, in a nod to this, Chekov identifies himself as the "Acting Science Officer" of the Enterprise.

Chekov was added for a few reasons: to attract younger viewers and give a nod to the Russians in the space race. (Also to fill in some of Sulu's role while Takei was filming The Green Berets.)

Koenig is reprising his role for the Fan Film series Star Trek: Renegades, where Chekov is now over a hundred and an admiral.

  • Ambiguously Jewish: An idea with some popularity in the fandom, partially since Koenig (and Anton Yelchin, who played Chekov in the 2009 reboot) are Jewish.
  • Butt-Monkey: Chekov did more screaming-in-pain than the rest of the crew combined. He even got a torture scene in the episode "Mirror, Mirror." This was explained as a convenient way to show there was mortal peril. Apparently, Kirk, Spock, and McCoy, all being older, dignified men, would have made it improper for them to scream, but Chekov is in his early twenties and still very boyish, so it's all right for him. Doesn't make it any easier on the poor guy, though. In a nice inversion, he's the only one who doesn't get hit with the aging disease in "The Deadly Years." He still ends up getting subjected to a thousand and one medical checks, though.
    Chekov: Blood sample, Chekov! Marrow sample, Chekov! Skin sample, Chekov! If—if I live long enough, I'm going to run out of samples!
    Sulu: You'll live.
    Chekov: Oh yes, I'll live. But I won't enjoy it!
  • Cloudcuckoolander: Chekov's constant references to Mother Russia appear to only make sense in his mind.
  • Cultural Posturing: What didn't Mother Russia invent?
  • A Day in the Limelight: "Mirror, Mirror," "The Trouble With Tribbles," "The Deadly Years," and "The Way to Eden."
  • Deadpan Snarker: Not as much as Bones or even Spock, but he definitely has a smart-assed side. As he gets older, it gets worse.
  • Glorious Mother Russia: This trope is very much in effect with Chekov. He is the only person on the Enterprise's bridge who speaks with a thick, nearly incomprehensible accent (in the company of an African, an East Asian, and a half-alien), and much of his dialogue is Cultural Posturing about how Russia is the greatest country in the world that has apparently inwented everything.
  • The Intern: Much is made of his relative inexperience and impulsiveness.
  • Know-Nothing Know-It-All: Chekov both amused and annoyed his crewmates by spouting what he didn't know about Russian history.
  • Mr. Fanservice: Really. Brought in specifically to appeal to younger Fangirls, complete with hair straight out of The Monkees.
  • Plucky Comic Relief: Particularly as the films progressed.
  • Rank Up: At some point prior to Star Trek II: The Wrath of Khan, he got promoted to Commander.
  • Running Gag: "It vas inwented in Russia."
  • Russian Guy Suffers Most: Oh, yeah.
  • The Scream: Walter Koenig had a good one, which is why it's Chekov who always gets stuffed into the agony booth, shot, driven insane, tortured by Klingons, implanted with parasitic worms... Koenig lampshaded this by jokingly calling the second movie in the series "Star Trek II: Chekov Screams Again."
  • Sixth Ranger: Subverted. Chekov didn't appear on the show until Season 2, but apparently served on the Enterprise long before he appeared, because in the second movie, Khan recognizes Chekov, apparently having met him in the Season 1 episode "Space Seed."

    Walter Koenig's explanation for how they met is that Chekov actually was serving aboard the Enterprise but was on duty during the night shift, and he and Khan met off-screen. The circumstances of their meeting were thus: Chekov was using the bathroom and he was taking an inordinately long time, and Khan approaches that very same bathroom, needing to use it. Finding it occupied, he soon loses his patience and pounds on the door. When Chekov finally emerges, Khan grabs him and fixes him with a Death Glare, and says "I will never forget your face!" This is further compounded by the fact that he expended all the toilet paper.
  • Those Two Guys: With Sulu.

    Nurse Christine Chapel
Played by: Majel Barrett

The ship's nurse, known for her attraction to Spock.

  • A Day in the Limelight: "The Naked Time," "What Are Little Girls Made Of?", "Amok Time," and "Plato's Stepchildren."
  • Deadpan Snarker: "You know, self-pity is a terrible first course. Why don't you try the soup?"
    • "Come along, Ensign. This won't hurt. Much."
  • Hair of Gold, Heart of Gold: Blonde and among the Enterprise's most caring officers.
  • No Name Given: In the series, Chapel was always addressed by her position rather than her rank. She is formally promoted to Lieutenant later on in the five-year mission, and by the time of the first movie, has an MD under her belt, and is prepared to assume the role of Chief Medical Officer. We can therefore assume that, especially given her position as Head Nurse, she was a junior officer (probably a mustanged Ensign, given her backstory).
  • Rank Up: When she reappears in Star Trek IV: The Voyage Home, she's a doctor.
  • Real Life Writes the Plot: Majel Barrett was the girlfriend and eventual wife of Gene Roddenberry, which may explain why we saw Nurse Chapel so much. In part, her role was also expanded in the latter half of the first season (after only sporadically appearing in the early episodes) due to Grace Lee Whitney leaving, and Nichelle Nichols also threatening to quit, which would have left the show without any recurring female characters.
  • Single Woman Seeks Good Man: Roger Korby, her fiancé, was a man to whom "life was sacred" by her own description. Given that her reasons for crushing on Spock included his honesty, it seems this applies across the board for Chapel.
  • Tomboy and Girly Girl: Her girly girl to Nyota's tomboy.

    The Enterprise
Played by: Majel Barrett (computer voice)

"No bloody A, B, C, or D!"
Scotty, "Relics"

The most powerful armed ship in Starfleet, and the main method of transit for the entire cast. Alongside Kirk and Spock, she appears in every episode of the series, and is very often regarded as a character in her own right, both in and out of universe; in fact she is the only character mentioned in the legendary opening narration ("these are the voyages of the Starship Enterprise").


Recurring Characters:

    Yeoman Janice Rand

  • '60s Hair: The aforementioned beehive below.
  • Beehive Hairdo: The infamous basketweave hairdo. Whitney's wig is supposed to be a 'futuristic' version of the contemporary beehive. From Lisabeth Shatner's (daughter of Bill) memoirs of being on-set:
    Eventually, I began looking around the room, and discovered I had a bird's eye view of the top of the actress's head. I was utterly fascinated by her hair, which was woven into a checkered pattern on top. I stared at that hair for a long time, wondering if it was possible to actually play checkers on it.
  • Bridge Bunny: The Trope Codifier.
  • The Bus Came Back: She became the Transporter Chief in the first film, had a cameo in Star Trek III, and was Captain Sulu's communications officer in Star Trek VI. She also appears in a flashback episode of Voyager set during her time serving aboard Sulu's ship. Tuvok nerve-pinches her, allowing Janeway to borrow her uniform. (Which, as SFDebris laughingly pointed out, is unlikely as Whitney had at least three cup sizes on Mulgrew.)
  • Chuck Cunningham Syndrome: Vanished halfway through the first season due to off-screen issues. She was replaced by Dr. Helen Noel in "Dagger of the Mind".
  • Damsel in Distress: She ends up endangered more than once, including being attacked by an evil clone of Kirk, temporarily zapped out of existence, and kidnapped and tied up by the Onlies.
  • Dangerously Short Skirt: And Rand is why it was so short in the first place. Grace Lee Whitney was a dancer, and pushed for the uniform to better show off her legs.
  • Mundane Utility: Yeoman Rand heated coffee with a phaser in "The Corbomite Maneuver."
  • Hypercompetent Sidekick: Implied; there are several references to her ability to keep Kirk from being swamped in paperwork, and one to improvising with a phaser when the food systems won't provide hot coffee.
  • Miss Fanservice: The original media package described her as having "a strip queen's figure that a uniform can't hide." Not that those uniforms hide much, but whatever.
  • Rank Up: In the series, she was a yeoman. In The Motion Picture, she's chief petty officer and transporter chief. In The Voyage Home, she's a communications officer assigned to Starfleet Command on Earth. Finally, in The Undiscovered Country, she's communications officer on the Excelsior, going from Lieutenant junior grade to commander.
  • Satellite Character: With the exception of "The Man Trap," where she hangs around with Sulu for a large part of the episode, and "Charlie X," where she's the unwanted focus of Charlie's attraction until he (temporarily) zaps her out of existence, she has no significant interaction with any character other than Kirk.
  • She's Got Legs: Janice Rand, and more specifically Grace Lee Whitney herself, is why the Starfleet miniskirt was so short. Whitney was a dancer, and wanted to show off her stems.
  • Suspiciously Similar Substitute: She herself is one, to Yeoman Colt from "The Cage" and Yeoman Smith from "Where No Man Has Gone Before". A Will They or Won't They? romance between the Captain and his female Yeoman (note that both Pike and Kirk explicitly complain about their Yeoman being a woman) was a key element of Roddenberry's concept for the series from the very beginning, and it took quite some time (and him stepping down as active showrunner in favour of Gene Coon) before it was finally abandoned.
  • Unreplaced Departed: Rand was intended to be a series regular as a recurring love interest for Kirk, and was featured even more prominently than Spock and McCoy in promotional materials, and indeed was a major fixture of the first half of season one. She was eventually cut from the show by the halfway point of the series.note  Although Rand's role as Kirk's aide was taken up by the occasional background extra, there was never a permanent replacement for her character.
  • Unresolved Sexual Tension: With Kirk.

    Lieutenant Kyle
Played by: John Winston

  • The Cameo: He's the communications officer on the Reliant in Star Trek II: The Wrath of Khan.
  • Mauve Shirt: Because he was the only recurring redshirt not played by an extra, he usually had much more dialogue than other redshirts, a consistent name and position on the ship, and was allowed to play an active role in the plot (see "The Doomsday Machine" or "Mirror, Mirror" for examples).
  • Only One Name: Though non-canon sources have variously used both "John" and "Winston," both obviously in tribute to the actor.
  • Teleporters and Transporters: Contrary to popular belief, he was the Transporter Chief, not Scotty. Like other redshirts, he was occasionally seen on the bridge, though usually he was explicitly pinch-hitting for someone else (as in "Who Mourns For Adonais?" when Spock has taken command and Chekov is in the landing party, and Kyle mans the science station).
  • What Happened to the Mouse?: We never see him on-screen again after being marooned on Ceti Alpha V, which caused much speculation about his fate, despite Kirk's log entry that they are heading there to pick up the crew of Reliant. The non-canon novels and comics established that he survived his unwanted shore leave on the planet, and eventually ended up on the Enterprise-A.

    Lieutenant Leslie
Played by: Eddie Paskey

  • Inexplicably Identical Individuals: A common fan theory is that there is multiple Leslie brothers or clones, due to Leslie's occasional tendency to be seen on the bridge in one shot, then behind Scotty in engineering in the next.
  • Omnidisciplinary Scientist: By virtue of Paskey being the omnipresent extra on set, Leslie is seen working in literally every conceivable position on the ship, from medical to security to transporter operation.
  • Only One Name: And only referred to by that name on a few occasions. Various non-canon sources have called him "Frank," "Ryan," or "Ed" (the last, naturally, after the actor).
  • Throw It In!: His otherwise un-named character was given a name by none other than William Shatner, who named Lesley after one of Shatner's young daughters.
  • Red Shirt: The King of the Redshirts, no less, as he has the distinction of being the first Trek character to die and return to life. He dies in "Obsession", yet turns up later in the episode completely unharmed. Paskey was Shatner's stand-in and lighting double, and Doohan's hand double, so they couldn't really get rid of him, and he actually appears in more episodes than Chekov.

    Lieutenant Kevin Thomas Riley
Played by: Bruce Hyde

  • Ascended Extra: Actor Bruce Hyde was cast as a crewman with a significant part in "The Conscience of the King" without anyone realizing he had also played uber-Irishman Riley in "The Naked Time." When the producers finally realized this, the script was hastily re-written so that Hyde played the same character in both episodes. (The same thing happened with actress Barbara Baldavin, who appeared three times as Angela Martine but is accidentally addressed by other names more than once due to rewrites; figuring out who she really is almost approaches Continuity Snarl levels.)
  • Dreadful Musician: "Iiiiii'll taaaaake you hooome again, Kathleeeeeen...."
  • He Knows Too Much: Lenore poisons him, Hamlet-style, to prevent him from pointing at Kodos as a war criminal. (Ironically, he doesn't even know that Kodos is aboard until near the end.)
  • Improbable Age: Riley seems pretty young for a full-braid Lieutenant - Hyde was 24 at the time, and looked it. This also makes him an improbable witness to a man who had disappeared 20 years before, when he would have barely been out of diapers. Amusingly, the greenhorn Ensign Chekov, introduced in the second season, was played by an actor five years older.
  • Incessant Music Madness: "And now, crew, I will render Kathleen ONE MORE TIME!
    Kirk: Please, not again.
  • Oireland: Got his "Irish" up when under the influence of the mind virus in "The Naked Time."
  • Real Life Writes the Plot: The reason Riley never returned after "The Conscience of the King," despite being very popular with fans, was that Hyde left to become a hippie. Yes, really. Remember, this was 1967. (He later became a professor of philosophy.)

    Doctor M'Benga
Played by: Booker Bradshaw

The ship's ranking Chief Medical Officer when Bones was off the ship, Doctor M'Benga interned on Vulcan and specialised in treating Vulcan physiology, which came in useful when Spock was shot.

  • All There in the Manual: The character originated in an ultimately unused script, which gave his first name as Joseph and his nationality as Ugandan. An early novel used "Geoffrey" and the Star Trek Novel Verse named him Jabilo.
  • Cruel to Be Kind: Spock needs to be put in pain to be brought out of his trance, so Nurse Chapel taps him gently. Scotty pulls Chapel away from Spock, thinking she's gone mad, slapping her patient around. Then M'Benga steps in and gives Spock the necessary physical stimulus.
  • The Main Characters Do Everything: Averted in the episodes he showed up. He fills in for Bones when the latter joins a landing party.
  • What Happened to the Mouse?: Never even mentioned outside his two appearances, despite the many times his specialisation in Vulcan medicine would have been useful, and being Bones' second-in-command.

    Ambassador Sarek 
Played by: Mark Lenard
Dubbed in French by: Roger Rudel (Star Trek III), Georges Berthomieu (Star Trek IV), Mario Santini (Star Trek VI)

Father of Spock. A distinguished Vulcan Diplomat, he and Spock were not on speaking terms for some time prior to the former's first appearance in "Journey to Babel" (to the point where Spock never even mentioned to Kirk or Bones that they were related). Sarek had wanted his son to follow him in his footsteps by attending the Vulcan Science Academy, but instead, Spock chose to join Starfleet. Appears in only one episode of the Original Series, but returns in the films, the Animated Series, and even Star Trek: The Next Generation.

  • Abusive Parents: Not intentionally, but cold Vulcan logic means he was emotionally distant toward Spock when he was a kid, and it's helped cause a lot of Spock's anti-human attitude. Sort of tells you what his parenting styles are like when Spock's reaction to being told Sarek's at threat of dying is "meh". Fortunately, they manage to repair their relationship.
  • Ambadassador: He's proficient in Vulcan martial arts. Spock points out that he could be a plausible suspect in the Tellarite ambassador's murder since Sarek knows the technique that killed him.
  • Antiquated Linguistics: Introduces Amanda as "she who is my wife" rather than just "my wife". He does the same thing decades later with Perrin.
  • Blue Blood: Or at least he comes from good family, in so far as Vulcans count such things, and behaves in a courtly manner.
  • Gentleman and a Scholar: A cut line indicated that Sarek was an astrophysicist before he turned to politics.
  • Happily Married: Though Sarek and his human wife, Amanda, have their differences (as seen in "Journey to Babel"), and though he's culturally inhibited from expressing his emotions, it's clear the couple love each other very much.
  • Has a Type: When he resurfaces in Next Generation, he has remarried after the death of his human wife Amanda... to another human woman.
  • Jerk with a Heart of Gold: For all his stern, no-nonsense traits and his differences with his son, he is a loving father and proud to represent his planet for the Federation.
  • Killed Off for Real: Died in the Star Trek: The Next Generation episode "Unification I".
  • Marry for Love: Marrying Amanda was... logical. Obviously. (Well, if you love them, marrying them is pretty logical.)
  • Not So Stoic:
    • He teases Amanda in public at the end of "The Way to Babel".
    • With a side order of OOC Is Serious Business. In Star Trek III, he's visibly angry when he confronts Kirk about the latter's supposed failure to return Spock's katra to Vulcan. This only escalates when he figures out Kirk has no idea what the hell he's talking about. This is lampshaded later at the foot of Mount Seleya, when Sarek requests the Fal-tor-pan ritual be performed to reunite Spock's body and mind. High Priestess T'Lar protests that the ceremony is dangerous and its outcome uncertain, making his request illogical. Sarek replies "Forgive me, T'Lar. My logic is uncertain... where my son is concerned."
  • Out-of-Character Moment: In Sarek, Picard is shocked to see him moved to tears by a musical performance. This is because he has Bendii syndrome, which is analogous to Alzheimer's in a human.
  • So Proud of You: He admits this to Spock in Star Trek IV, and in TNG's "Unification: Part II," Spock learns from mind-melding with Picard that he was even prouder, which almost moves him to tears.
  • Super Strength: Like all Vulcans. That Tellarite ambassador mentioned earlier tried to manhandle Sarek during an argument. Sarek effortlessly knocks away his hands with just a flick of two fingers each sending him reeling quite some distance as an aftereffect. He's lucky Sarek didn't actually hit him.
  • You Look Familiar: In addition to Sarek, Lenard also played the Romulan commander in "Balance of Terror" and a Klingon captain in the first movie. He is the only actor to portray representatives of all three major galactic powers in the TOS continuity.

    Harcount Fenton "Harry" Mudd
Played by: Roger C. Carmel

  • Affably Evil: He's a shameless crook and totally unrepentant scam artist, but he's friendly, cheerful, easy-going, and surprisingly likable, so long as you remember never to trust him with anything, especially anything worth money. Basically, he's a proto-Ferengi.
  • The Aggressive Drug Dealer: In "Mudd's Women."
  • Character Outlives Actor: He was slated to make an appearance in Next Generation, but Roger C. Carmel died before that could happen.
    • A third TOS Mudd episode, titled "Deep Mudd," was actually written; it was a direct sequel to "I, Mudd" and would have had him escape the androids' planet by tricking them into revealing the location of a cache of super-advanced devices which then end up in the hands of a band of space pirates; unfortunately, Carmel was busy with another project and the script was dropped.
    • The producers of Star Trek IV: The Voyage Home also considered having him appear in a cameo as a character witness for the Enterprise bridge crew's trial. This would have been an ironic Continuity Nod to the end of "Mudd's Women," where Kirk jokingly offered to be a character witness at Mudd's trial.
    • Harry finally reappeared in Star Trek: Discovery, played by Rainn Wilson.
  • Con Man: His first appearance is based on his scam to marry gorgeous women secretly modified with drugs to be super-beautiful to lonely, wealthy space-workers for a huge payout. In Star Trek: The Animated Series, it's mentioned he once tricked an alien species by selling them the Starfleet Academy building.
  • Cool and Unusual Punishment: This gets visited upon him by Kirk at the end of "I, Mudd."
  • Full-Name Ultimatum:
    Stella: Harcourt! Harcourt Fenton Mudd!...
  • Henpecked Husband: It turns out in "I, Mudd" that he had a harridan of a wife named Stella; part of the reason he became a crook was to run away from her to the ends of the galaxy.
  • Hoist by His Own Petard: By the Stella androids at the end of "I, Mudd."
  • Honest John's Dealership: The first storyline involving him is his plan to sell brides to lonely space-miners (after giving them illegal "Venus Drugs" to make them super-beautiful). He'd also been convicted as a smuggler prior to his first appearance. In his second appearance, he describes how he escaped Deneb V after being sentenced to death for fraud.
  • Lovable Rogue: He's a money-grubber and irresponsible, but he's affable and rarely trying to commit "truly evil" crimes.
  • Recurrer: He holds the distinction of being the only non-Starfleet character in the entire series to appear in more than one episode. He returns for an episode of the Animated Series, as well.
  • Retroactive Recognition: Roger C. Carmel was also the voice of Cyclonus. Really!

    Fleet Captain Christopher Pike 
Played by: Jeffrey Hunter ("The Cage"), Sean Kenney (Disfigured Pike in "The Menagerie")
Dubbed in French by: Yvon Bouchard

The previous captain of the Starship Enterprise and Spock's prior commanding officer. A celebrated space explorer, much like Kirk, he was later horribly disfigured in a training accident. Spock's loyalty to Pike was too much to allow Pike to remain a disabled wreck, so he returned Pike to the Talosians to live out his days in an illusion of good health with his love Vina.

  • And I Must Scream: The training accident he was in gave him a huge dose of delta radiation, bad enough that he's completely immobilized. McCoy notes his brain is working as much as anyone else's, but he can't even speak. And when he realises what Spock's doing, all can he do is repeat "no" over and over again.
  • Body Horror: What we see isn't pretty. His face is covered in scarring, and one massive burn going from chin to temple on the right side of his face. And it's hinted the radiation did a lot of other damage, given mention is made of his heart being kept operated by battery. Even getting agitated nearly puts him into a coma from the strain.
  • The Captain: The original captain, preceding even Kirk. He later became a fleet captain.
  • The Determinator: The Talosians expected Pike to quietly accept captivity. Pike had other ideas and didn't stop until he escaped.
  • Due to the Dead: Star Trek: Deep Space Nine revealed that Starfleet named one of their combat decorations in his honor, the Christopher Pike Medal of Valor.
  • A Father to His Men: Implied from how Spock was willing to risk his career and life to help his former CO.
  • Hollywood Mid-Life Crisis: "The Cage" can be interpreted as an extended metaphor for a man going through a mid-life crisis. (Gene Roddenberry was well into his forties when he wrote the pilot, and even cast his mistress as the female lead.) Pike's character is clearly supposed to be older than Kirk, even before the eleven-year Time Skip in "The Menagerie", although Hunter was a relatively young man (he turned 38 during filming of "The Cage"). Subsequent depictions of the character clearly portray him as middle-aged even during his prime (played by 53-year-old Bruce Greenwood in Star Trek (2009) and 45-year-old Anson Mount in Star Trek: Discovery, both set some years before the TOS era).
  • Once for Yes, Twice for No: Following the accident, Pike is left in a state where his only form of communication is a light on his elaborate wheelchair, which he can light once for "yes" and twice in a row for "no".
  • Small Role, Big Impact: He only appeared in two episodes, one of which didn't air until decades after the show ended, yet is easily one of the most recognizable things from TOS. His blinking lights and wheelchair have been been parodied and paid homage to in numerous other works.
  • Unresolved Sexual Tension: The Talosians noted that both Pike's first officer, the original Number One, and his yeoman were attracted to him, but since we never saw anything further of Pike's adventures, we don't know if anything came of it. He was apparently still in love with Vina as he later accepted retirement with Talosians to be with her.
  • The Voiceless: The training accident left him unable to speak, so he had to communicate via blinking lights on his wheelchair. One blink for yes, two for no.

    "Number One" 

"Number One"

Played by: Majel Barrett

The first officer of the Enterprise and the second-in-command to Captain Pike, originally filling the cold, logical first officer role that would later go to Spock. She only appeared in "The Cage" and footage reused in "The Mengerie".

  • Commanding Coolness: As per her rank as first officer.
  • Consummate Professional:
  • Everybody Calls Him "Barkeep": Everyone calls her Number One, all the time.
  • Number Two: As the Enterprise's first officer.
  • Only One Name: She's only referred to as "Number One" in "The Cage". A variety of apocrypha over the years either confirmed this as a given name or title on her homeworld, or suggested various real names, such as Una.
  • Real Life Writes the Plot: Majel Barrett was the girlfriend and eventual wife of Gene Roddenberry, which caused suspicion among NBC executives when they viewed "The Cage". She was removed from the show and not acknowledged again for decades.
  • The Stoic
    • Not So Stoic: When Pike remarks that he "can't get used to having a woman on the bridge.", she looks openly surprised before he excludes her as "different, of course."
  • Unresolved Sexual Tension: The Talosians noted that she was attracted to Pike, and her official biography confirms this, but we don't know if anything came of it. He was apparently still in love with Vina as he later accepted retirement with Talosians to be with her.
  • You Look Familiar: Majel Barrett was later cast Christine Chapel on TOS after Number One was removed from the show (which NBC executives were not informed about) and much later, she also played Lwaxana Troi in Star Trek: The Next Generation, and was the official Computer Voice in most Star Trek productions over the years. She also played most of the female characters except for Uhura in Star Trek: The Animated Series... she has several paragraphs on the relevant page.


    Khan Noonien Singh
"Do you know the Klingon proverb that tells us revenge is a dish that is best served cold? It is very cold in space."
Dubbed in French by: François Chaumette (Star Trek II)

"Social occasions are only warfare concealed."

A 20th-century genetically-engineered tyrant who ruled a quarter of the world in the 1990s. As his fellow "supermen" (or Augments) were overthrown, Khan and roughly 80 of his followers launched themselves into space in cryogenic sleep before being found by Kirk. With his weakness being his ambition, Khan then tried to seize control of the Enterprise with the help of Marla McGivers, the Enterprise ship historian whom he managed to seduce. It failed thanks to the crew's opposition and an attack of conscience from McGivers. Kirk then exiled Khan, his followers, and Marla to a remote but hospitable planet as an act of mercy, giving them the chance to build a new society. Unfortunately, not long afterwards, the planet suffered a catastrophic ecological disaster and, being completely forgotten by Kirk, Khan grew vengeful toward the man who cast judgement on him...

  • Absolute Cleavage: A Rare Male Example, his pecs are well displayed.
  • A Father to His Men: He saw his fellow super humans as a family, to the point where he vowed to avenge Joachim when he died following a crippling blast on the Reliant.
  • Affably Evil: In his first appearance, Khan's pretty charming, polite, and a bit of a rogue, just like Kirk. However, come Wrath of Khan and Khan is just losing it.
  • Alas, Poor Villain: At the end of Wrath of Khan, he's lost everything, including his beloved wife as well as his people, along with any hope of being able to establish a society for them. As he's left to die in the exploding Reliant, he remains Defiant to the End, reciting dialogue from Captain Ahab in Moby-Dick before the Reliant explodes. All that potential he had as a superhuman was essentially wasted out of a desire for control and revenge.
  • Ambiguously Brown: He's a genetically-augmented human from some point in the late 20th century. Culturally, he's a North Indian Sikh, but as he is also a genetically-engineered human, his DNA could contain many different genetic traits (his Mexican accent, however, is difficult to explain).
  • Anti-Villain: Cruel and immoral his actions may be, he wants a society that he and his people can thrive in, no matter how many others have to suffer for it.
  • Arch-Enemy: More than a hundred years later, Spock would credit him as being "the most dangerous adversary the Enterprise ever faced."
  • Ascended Extra: Goes from a random Villain of the Week to the main antagonist of The Wrath of Khan and one of the franchise's most iconic villains.
  • Awesome Mc Coolname: You can't go wrong with a name like "Khan."
  • Been There, Shaped History: Given that "Space Seed" states Khan lived in the late 20th century and "it's 2001 and Khan wasn't on the cover of People magazine," two novels titled The Rise and Fall of Khan Noonien Singh tries to explain that the Eugenic Wars was some sort of Secret History. Among Khan's achievements are fighting the USSR alongside Afghanistan, causing a plane crash that killed the leader of the Pakistan's military government, and opening a hole in the ozone layer (and in a kind of Actor Allusion, his hideout is an island in the French Polynesia).
  • Bread and Circuses: His ruling style back when he was a dictator over a fourth of Earth, at least compared to his competitors, which was enough to give him a legacy as "the best of tyrants." Notably, there were no massacres under his rule, and he didn't involve himself in the Eugenics Wars until after his territory was attacked. On the other hand, the people under his rule were reduced to subjects with few freedoms.
  • Breakout Villain: Originally just a Villain of the Week. Ever since Wrath of Khan, he's arguably the most highly-regarded villain in the entire franchise.
  • Classic Villain: Khan represents a nice combo of Pride and Wrath.
  • Control Freak: Khan demands absolute obedience from everything. While some of his followers can object, none of them will sway him from his course.
  • Damned by Faint Praise: He is seen as "the best of tyrants" in regards to the Eugenic Wars.
  • Dramatically Missing the Point: A fan of Moby-Dick, Khan sees himself as Captain Ahab and Kirk as his White Whale. Khan seemed to have forgotten how Ahab's quest for vengeance ended. Not with self destruction; he understands and accepts that, but with the fact that Ahab didn't even get a chance to make sure he succeeded.
  • The Dreaded: Even a century after his death, Starfleet is still terrified of him. It's outright said that the main reason the Federation still has a No Transhumanism Allowed policy in the DS9 era is because they're scared of a new Khan rising from the ashes. His reputation even extends into a new timeline: When young Spock asks for information about Khan, Spock breaks his own oath not to tell him about the future to warn him about how dangerous Khan is, outright saying that he's the most dangerous enemy the Enterprise ever faced.
  • Even Evil Has Loved Ones: While he started manipulating Marla McGivers to betray Starfleet as a tool to escape, he came to passionately love her after she joined him in exile. He forgave her betrayal of him to her old crew, and she ruled as his queen. Her death on Ceti Alpha V—more than that of his other loyal followers—is what drives the man who once conquered a quarter of Earth.
  • Evil Overlord: Back in the day, anyway. He tries to give it another go in "Space Seed" but is thwarted and offered the opportunity of becoming one to an abandoned planet. But when the planet unexpectedly suffers a catastrophe that devastates him and his followers, he settles on a simpler motive.
  • Fatal Flaw: His pride. In The Wrath of Khan, he is pressed to pursue the Enterprise into the Mutara Nebula once Kirk tells him "I'm laughing at the superior intellect."
  • Faux Affably Evil: Becomes one in The Wrath Of Khan, blinded by his desire to get revenge on Kirk. That doesn't undermine his intelligence, though.
  • Genius Bruiser: A Superhuman with immensely powerful physical and mental capabilities.
  • Glass Cannon: Has the physical strength to bend a phaser in half with his bare hands and effortlessly lift a spacesuit-wearing Chekov with one arm, but gets taken down by Kirk with a pipe.
  • Hero Killer: He was directly responsible for Spock's death in the second movie. Hard to fit the Trope more plainly when you've done that.
  • Karma Houdini: He was this In-Universe for his crimes during the Eugenics Wars. While all the other superhumans were implied to have been killed or imprisoned, Khan managed to escape on the Botany Bay. Even when he's later released by the Enterprise crew, there's no serious talk of putting him on trial and he's eventually given a whole planet of his own to rule. Then Ceti Alpha VI exploded, depriving Khan of his beloved wife and sentencing him to a hellish existence on a Death World.
  • Morality Pet: His possible son Joachim, who he genuinely loves and cares about.
  • Motive Decay: Initially, all he wants is to create a society where he and his people can thrive, but by the time of The Wrath of Khan, all he wants is revenge against Kirk.
  • Mr. Fanservice: He's almost always wearing an outfit that displays his muscular chest and great physique.
  • My God, What Have I Done?: Khan's final moments include one of these with the death of Joachim who may very possibly be his biological son and almost certainly is his adopted son. The fact he realizes he got him killed doesn't deter him from further actions, though.
  • No Shirt, Long Jacket: In the movie (though the jacket is quite damaged), to show off Montalban's great shape.
  • No Transhumanism Allowed: In Star Trek: Deep Space Nine, it's explained that Khan is the reason the Federation prohibits genetic modification or engineering.
  • Photographic Memory: Implied to be one of his genetically engineered gifts, and stated explicitly in the novelization of Wrath of Khan and the expanded universe's "Khan trilogy". He tells Chekov he never forgets a face, and even after 15 years he still seems to have the Enterprise's technical specifications committed to memory, given that he still has perfect knowledge of the ship's weak points.
  • Pride: He has oodles of it.
  • Reasonable Authority Figure: At least to his fellow superhumans. His interactions with Joachim in Wrath of Khan show that his followers are comfortable enough with him to give him critical feedback without any hesitancy, although in the end his own authority is absolute.
  • Remember the New Guy?: In both Star Trek Into Darkness and his debut episode Space Seed, each set in different continuities, Khan Noonien Singh is established to be a genetically / eugenically engineered übermensch despot from the late 20th / early 21st century- the most prominent of several in fact-, who ruled various nations across the globe and who partook in a destructive global conflict known as the Eugenics Wars. Despite this, it takes them half an episode to identify him even after he interacts with several characters- including the ship's historian- whereupon both Kirk and Scotty admit to being aware of Khan and even admiring him somewhat, the ships' computer is shown to have photographs of him, and everyone on board knows about Eugenics Wars and the superhumans who started them, not to mention that he freely tells them his name from the beginning. The crew might as well have ran into a cryogenically frozen French general named Napoleon and failed to think he might be that Napoleon until the 11th hour.
  • Revenge Before Reason: He will do anything to kill Kirk, no matter how self-destructive. Even when Kirk is clearly baiting him into an obvious trap, Khan seems physically incapable of resisting the urge to roar into it, so fervent is his hatred.
  • Revenge Myopia: Khan ignores Chekov's observation that he attacked Kirk after the latter had taken in him and his crew.
  • Rule of Symbolism: Much of the conflict between Kirk and Khan plays out like Paradise Lost, with Kirk as God and Khan as Lucifer. Khan even lampshades this in "Space Seed." In The Wrath of Khan, he has two copies of Paradise Lost on his bookshelf (one which included Paradise Regained).
  • Sanity Slippage: By the time of The Wrath of Khan, he’s lost it thanks to being stranded on Ceti Alpha V and the death of his wife and most of his followers.
  • Sealed Evil in a Can: He and his cryogenically-frozen followers, in the episode "Space Seed." And again in Star Trek II: The Wrath of Khan, when he's abandoned on Ceti Alpha V (which the crew of the Reliant mistake for Ceti Alpha VI after a natural disaster alters its orbit and destroys its environment).
  • Sequel Adaptation Iconic Villain: Star Trek: The Motion Picture had the crew of the Enterprise confront V'ger as the antagonist. Wrath of Khan brought Khan back and more dangerous than ever.
  • Skilled, but Naïve: Other than his pride and ambition, one of Khan's greatest weaknesses is that fact that, despite his incredible intellect, all his knowledge and experience is that of a 20th century man, and he lacks the decades of experience in space that Kirk has. This shows when he's unable to quickly find the Reliant's command console override despite having memorized Starfleet's standard starship technical specifications, and when he fails to consider that space is three-dimensional during starship combat.
    Spock: He's intelligent, but not experienced. His pattern indicates two-dimensional thinking.
  • Social Darwinist: Khan is this, full-stop.
  • Soft-Spoken Sadist: In Wrath, at least regarding Kirk and all collateral damage.
    Khan: I've done far worse than kill you. I've hurt you... and I wish to go on hurting you.
  • Star-Crossed Lovers: He and his wife, a crewman on the Enterprise who suffered from Heel–Face Revolving Door Syndrome.
  • Take Over the World: Why Khan wants Project Genesis. With his homeworld destroyed and his people dwindling in numbers, he feels that terraforming a planet is the only way to ensure his and his people's continued existence.
  • Took a Level in Jerkass: Khan becomes far more ruthless and unhinged in The Wrath of Khan, thanks to his Sanity Slippage and singleminded vendetta against Kirk.
  • Tragic Keepsake: Khan wears a Starfleet emblem on a chain around his neck, strongly implied to have been part of Marla McGiver's uniform.note 
  • Tragic Villain: Subverted. Khan has all the hallmarks of a tragic character, having suffered a great loss that drives him to committing evil, but while he is sympathetic, he was a ruthless dictator even before this. The only thing it really changed was how evil he was, causing him to go from Affably Evil to a spiteful, unhinged demagogue.
  • Trouble from the Past: He perfectly embodies both the modern age's charismatic daring and its prideful ambition, transported through time almost 300 years to menace the utopian future of the 23rd century, which he comes to believe is ill-prepared to resist himself and his crew of supermen. Kirk ultimately proves him wrong on that account.
  • Ungrateful Bastard: Kirk and co find a stasis ship just in the nick of time, as Khan's own capsule is about to fail, revive him and his followers, and treat him with frankly undue courtesy given who he is—so Khan decides to steal his ship. Then Khan resents Kirk leaving him and his people on Ceti Alpha V, even though that was more lenient than taking him back to Earth, where he would have been prosecuted as a war criminal.
  • Visionary Villain:
    • Justifies his quest to Take Over the World as an attempt to unify humanity during a time of war.
    • Subverted by the movie, in which it becomes abundantly clear he isn't as interested in conquering as he is in killing one man over a grudge.
  • Wicked Cultured: His Famous Last Words come from Moby-Dick, he mentions Paradise Lost before Kirk exiles him, and the Botany Bay appears to have other classic books. Part of his obsession with Moby-Dick in particular seem to be because it seems that Khan was stuck on Ceti Alpha V with only a handful of books to read, leading him to read them over and over again.
  • Young Conqueror: Both Expanded Universe versions of his Origin Story (the 2001 novels by Greg Cox and the 2014 comic book tying in to Star Trek Into Darkness) place him as being either in his early or late 20's during the Eugenics Wars. The novels indicate that faster-than-normal maturation is part of his genetic modifications.

    Commander Kor
Played by: John Colicos

The main antagonist of "Errand of Mercy" and Kirk's first Klingon opponent. Technically he isn't Star Trek's first Klingon since several troopers are seen before him, but he is the primary Klingon in the episode which introduces the race. He returned in one episode of The Animated Series, three episodes of Deep Space Nine (undergoing a Heel–Face Turn with the rest of the Klingons), and more novels and comics than you can shake a stick at.

  • Affably Evil: Despite intending to execute Kirk once he discovers his identity, he has a drink with him first and is generally hard to dislike.
  • Enemy Mine: When the Organians demonstrate their powers and use nonlethal force on both sides, Kor is quick to whisper to Kirk that they should team up to take them on.
  • Evil Counterpart: Like Kirk, Kor is a senior field officer, but with the military dictatorship of the Klingon Empire rather than the democracy of the Federation.
  • A Nazi by Any Other Name: Kor's control of Organia involves restriction of personal freedoms, mass executions, and constant surveillance.
  • Not So Different: Kor tries to pull one of these on Kirk, saying they are both warriors on a world of cowards. However, he is horrified when the Organians pull one on him and say one day humans and Klingons will be friends.
  • Proud Warrior Race Guy: Unlike many TOS Klingons, Kor does seem to embody this trope.
  • Small Role, Big Impact: John Colicos played Kor only once on TOS before reprising the role decades later on DS9, but his Genghis Khan-inspired performance set the standard for all Klingons.
  • Yellow Peril: Kor's look was based on Genghis Khan.


Harmless little fuzzballs featured in three episodes — "The Trouble with Tribbles" (TOS), "More Tribbles, More Troubles" (TAS), and "Trials and Tribble-ations" (DS9); and cameos in Star Trek III: The Search for Spock, Star Trek (2009), and Star Trek Into Darkness.

  • Born as an Adult: And pregnant. Which is quite a time-saver.
  • Cuteness Proximity: For some reason, people tend to enjoy cooing over the fluffy, purring fuzzballs. Well, unless you're a Klingon.
  • Explosive Breeder: Up to Eleven, and then some. In three days, one tribble will become 1,771,561. (Assuming that tribbles reproduce every twelve hours with an average litter of ten.)
  • Now You Tell Me: "We stop feeding the tribbles and they stop breeding!"
  • Sitcom Arch-Nemesis: The only species that the Tribbles do not like are the Klingons, and the feeling is very mutual.
  • Thrown Out the Airlock: Where they'll be no tribble at all.

    Lieutenant Gary Mitchell 
Played by: Gary Lockwood

The antagonist of "Where No Man Has Gone Before." Mitchell was Kirk's best friend until contact with the great barrier at the edge of the galaxy gave him extra-sensory perception and psionic powers, leading him to believe that he was becoming a god.

  • Anti-Villain: At first. His initial acts of villainy are simply attempts to stop Kirk and Spock from killing him out of fear for his power. He gradually becomes more evil over the course of the episode and by the end he's left this trope far behind.
  • A God Am I: He frequently refers to himself as such. During the final confrontation he uses his telekinesis to force Kirk to kneel and pray to him.
  • Forgotten Fallen Friend: The end of the pilot does give the crew a little time to grieve over him, but he's never mentioned again (the for-some-time-ambiguous canonicity probably didn't help), with his role as Kirk's close trusted friend getting transplanted onto Spock and McCoy (in fact, some fans watching the pilot get the impression that Mitchell was supposed to be first officer before Spock).
  • Glowing Eyes of Doom: After the accident, his eyes start to glow silver. His eyes return to normal when he's injured or is otherwise prevented from using his powers.
  • Hoist by His Own Petard: He is killed when he is crushed by rocks while standing in the grave he created for Kirk.
  • Jerk with a Heart of Gold: Prior to his transformation.
  • Physical God: He starts out gaining telepathy and telekinesis (powerful enough to deflect phaser fire and take control of the Enterprise through thought alone), and eventually evolves to nearly Q and Trelane's level, being able to will matter into existence through thought alone. Being crushed by rocks still kills him, though it takes being weakened in a psychic fight with another god-like being to get to that point.
  • Power Echoes: He eventually gains this.
  • Shock and Awe: After Kirk manages to convince Dr. Dehner to pull a Heel–Face Turn, she and Mitchell blast each other repeatedly with lightning, resulting in a Double Knockout; unfortunately Mitchell recovers relatively quickly, while Dehner is fatally wounded.
  • The Stoic: He quickly loses all traces of human emotion.
  • Super Strength: After being briefly Brought Down to Normal after a psychic duel with Dr. Dehner, Mitchell gets into a fist-fight with Kirk in which Kirk initially has the upper hand, until Mitchell starts regaining his powers; even without his telekinesis, he's strong enough to flip Kirk with an Off Hand Back Hand and lift a huge boulder and toss it at Kirk.
  • Tragic Monster: As Kirk says, Mitchell never wanted this to happen to him.
  • Übermensch: He believes that he has become a higher being who is destined to change mankind forever.
  • We Hardly Knew Ye: Despite being best of friends with Kirk for years, Mitchell never gets mentioned again in subsequent episodes or the films. Mind you, some show and character development establish Spock and Bones as Kirk's best friends on the ship, and Mitchell becomes more or less a villain of the week.
  • With Great Power Comes Great Insanity: After he starts mutating, he's initially relatively normal and only attacks the crew because they're considering killing him out of fear he'll evolve to the point where he starts to see human beings as insects. Pretty soon, though, he evolves to the point where he sees human beings as insects, losing all empathy for them and even demanding to be worshipped as a god.

     The Gorn Captain 

Captain of a vessel that attacked a Federation colony and lured the Enterprise to the ruins of it for an ambush, before being forced to battle Kirk to the death by aliens called the Metrons, where it is revealed that the Gorn only attacked because they considered the colony to be the prelude to Federation conquest.

  • Anti-Villain: While utterly ruthless about how they went about dealing with it, the Enterprise crew concedes that they had no clue the colony was infringing on Gorn territory and that such a thing would look like an act of aggression if things were reversed. In the mind of the Gorn, they are acting in self defence.
  • Attack Its Weak Point: During their initial fight, Kirk manages to briefly stun him by slamming the ear-like nodes on his head. It looks like Kirk managed to hit a vulnerable spot, because the Gorn is otherwise tough enough to No-Sell a microwave-sized rock to the clavicle.
  • Genius Bruiser: It looks like a brutish lizard monster that Kirk can't put down, yet it repeatedly outsmarts both Kirk personally and the Enterprise as a whole. Also, instead of relying on his superior natural strength, he takes the time to fashion a weapon from the location environment, just like Kirk does; however, he made a flint knife while Kirk made a cannon.
  • Implacable Man: The Gorn Captain shrugs off every physical attack Kirk hits him with and even gets back up when Kirk drops a boulder on him.
  • Made of Iron: As Kirk himself notes during the episode, the Gorn Captain easily takes attacks from Kirk that would kill a human being. Even Kirk dropping a boulder on him only knocked him out for no more than a minute, and didn't injure him at all.
  • Mighty Glacier: Much more powerful and durable than Kirk, yet moves about as fast as molasses in January.
  • Proud Warrior Race Guy: Implied, since their first response to finding a Federation colony on their territory is to utterly destroy it and set a trap for the nearest Federation starship, and they prove to be superior both tactically and in terms of firepower.
  • Super Strength: Kirk manages to pick up a large rock (maybe 60-80 pounds) and throw it at the Gorn Captain, hitting him square in the chest and accomplishing nothing. In response, the Gorn Captain easily picks up and lifts over his head a boulder that has to weigh at least a ton, and throws it (judging by the arc and how much time Kirk had to see it coming and dodge) probably fifty feet.


How well does it match the trope?
