* BestKnownForTheFanservice: "The Menagerie".
** "The Naked Time": A shirtless ''and freaking ripped as hell'' Mr. Sulu. Oh my!
* CargoShip:
** Kirk and the ''Enterprise'', the only lady he truly loves. Made hilarious by one episode in which the ship's computer is programmed to call him "dear".
** Hell, in "Elaan of Troyius" Kirk is able to single-handedly overcome a love potion just because he loved the Enterprise so much!
** And Scotty/Enterprise.
-->"Don't you think you should...rephrase that?"
* CompleteMonster: Melakon of the world Ekos was a devotee of Nazism introduced to his people in an attempt to soften it by a former Starfleet officer named John Gil. Shunning the attempt to water down Hitler's philosophy, Melakon decided to embrace Hitler's path. He overthrew his mentor and formed a fascist regime on his homeworld while trying to organize a new holocaust on an entire neighboring planet called Zeon. Before murdering his mentor, Melakon was denounced by him as nothing more as a self seeking adventurer: a traitor to his people and all they stood for.
* CrowningMomentOfHeartwarming - In "Amok Time" after Spock had believed he had killed his captain and friend. He went to [=McCoy=] and began readying himself for court martial, but just as he began giving [=McCoy=] orders to turn the ship over to Scotty, Kirk walked in behind him, snarking, "Don't you think you'd better check with me first?" Spock grabbed his friend by the shoulders, whirled him around, let loose with a beaming smile and cried, "''Jim!''" At which point every viewer watching squeed. Oh for... [[http://www.youtube.com/watch?v=6408JrvFNWc Here]]. First minute or so.
* CrowningMusicOfAwesome: Samuel Matlovsky's arrangement of strings and bass captures the combination of humor and seriousness of the situation in "I, Mudd."
* EarWorm: [[http://www.youtube.com/watch?v=_dnZHea_TI0 Gerald Fried's fight music]] of "Amok Time", which has been spoofed in ''TheCableGuy'', ''WesternAnimation/{{Futurama}}'' and ''WesternAnimation/{{The Simpsons}}''. '''Dun-Dun-DUN-DUN-DUN-DUN-DUN-DUN-Dun-Dun-DUN-DUN'''...
** From the same composer, the piece that plays throughout the episode "Shore Leave" often referred to as "Finnegan's Theme".
** Um, ''HELLO?!?'' Alexander Courage's theme music?
** It took decades, but La-La Land issued ''all'' the series' original music in a 15-disc set in 2012.
* EnsembleDarkhorse: Hikaru Sulu's popularity has gone ''way'' up in recent years, in no small part due to {{George Takei}}'s newfound prominence as a civil rights activist. Having an insane number of followers on {{Facebook}} and {{Twitter}} doesn't hurt either.
* FairForItsDay:
** Uhura: Although now it seems normal and unremarkable for a woman to have a job other than a secretary, back then Uhura being in a ([[MildlyMilitary almost military]]) job and being black was a huge leap forward.
*** Not only that, even when she primarily served as TheChick, casting a ''[[HumansAreWhite black]]'' woman in the role was a huge deal in the 1960s. And novels written as early as the '70s indicate that Uhura was far more than a glorified switchboard operator -- she is in fact a linguistic genius who can leave Kirk's head spinning with language theory. Also, Uhura was technically fifth in command of the ''Enterprise'' (and did take command for at least one episode of the animated series) meaning that out of the ''entire crew'' only Kirk, Spock, Scotty, or Sulu could override her decisions (although in one episode MauveShirt [=DeSalle=] takes command ahead of her).
*** One story going around is that Nichelle Nichols was considering leaving the show at one point, but Martin Luther King, Jr. himself told her how much the world needed to see an African-American woman on television being treated as an equal by white characters.
** Sulu: Not to the same degree as Uhura, but it does not seem particularly notable or progressive today to have an Asian supporting character while all the leads were white. However, in the 1960s, it was a ''pretty big deal'' that Sulu had no accent, did not do martial arts, and overall was not an offensive stereotype of Asians. Just about every Asian-American actor was clamoring for the role as a result.
*** Of course, martial arts did eventually creep into Sulu's character by the third movie, and one animated series episode has a slightly uncomfortable joke about Asian racial stereotypes.
*** And he was going to have a big martial arts scene in "The Gamesters of Triskelion" before Takei had to bow out of the episode, resulting in him being replaced with Chekov and the scene becoming a standard '60s TV fight.
** While marred by the pop-culture idea that he's a playboy, the fact remains that even for today's standards, Kirk is one of the few male heroes who use the stereotypically feminine technique of using their sexuality to get information.
** Having a Russian character on American TV ''at all'' in the 1960s, let alone making him one of the show's protagonists and showing him to have the main responsibilities over a military(ish) vessel's weapons system, was also pretty revolutionary for its time.
* {{Fanon}}
** Trelane was [[Series/StarTrekTheNextGeneration a member of the Q Continuum]]. Or, indeed, possibly even the ''same'' Q who later encounters Picard...
** [[WordOfDante Confirmed]] by PeterDavid in his TNG novel ''Q Squared''. Trelane is even implied to be [[spoiler:Q's illegitimate son.]].
** The (technically) two seasons which compromise ''WesternAnimation/StarTrekTheAnimatedSeries'' are actually the fourth and fifth year of [[FiveYearPlan the five year mission]] mentioned in the opening credits. The animated series isn't a different show, but the same one. Except its a cartoon.
** It's commonly speculated that Janice Lester in "Turnabout Intruder" was deemed too mentally unstable to command a starship and her psychotic mind twisted it into thinking that ''all'' women were forbidden from holding that position.
* FanPreferredCouple (so very, very much so it spawned the first SlashFic. Yep, Kirk and Spock again...)
** NichelleNichols revealed in 2011 that she auditioned for Spock. Who knows how that might have changed the history of fandom itself?
*** Nichols has been telling that story since the early 70s. Her audition was a formality, and she (supposedly) didn't know it. They didn't even have a character for her to be yet; Gene wanted her on the show because she was black, a good actress, and an old girlfriend. They gave her Spock's lines to read and at first she wouldn't do it because she wasn't going to play Spock. They joked that they could put pointed ears on her and call her a Vulcanita.

* FirstInstallmentWins
* GrowingTheBeard: [[AvertedTrope Averted]] by the series proper, the only ''Franchise/StarTrek'' series with a strong start. Among the movies, definitely ''[[Film/StarTrekIITheWrathOfKhan The Wrath of Khan]]'' - see also SurprisinglyImprovedSequel or EvenBetterSequel, depending on your view of the first.
* HarsherInHindsight:
** Evil Kirk's assault of [[BrotherChuck Rand]] during "The Enemy Within" is pretty awful in light of the fact that Grace Lee Whitney was later sexually assaulted by one of the ''[[Franchise/StarTrek Trek]]'' producers.
** In the episode "Assignment: Earth", Spock lists several scenarios that Gary Seven could have been sent to effect in 1968 Earth. One of them is "an important assassination". The episode aired March 28, 1968. MartinLutherKingJr was assassinated on April 4, 1968. To twist the knife even further, Robert Kennedy's assassination occurred just two months later.
** In the aftermath of incidents like the Manson murders, Dr. Sevrin's actions in "The Way To Eden" become a lot more disturbing.
** The message in "A Taste of Armageddon", about the dehumanizing effects of computerized warfare, was haunting enough in 1967, when the computer was still in its infancy. Today, with things like [=UAVs=] and computer-guided missiles becoming indispensable parts of modern warfare, it hits harder than ever.
** "Space Seed" ended with Kirk delivering a very optimistic line about the [[Film/StarTrekIITheWrathOfKhan future of Khan's people...]]
** "The Menagerie" when you consider that Jeffery Hunter (Captain Pike) was later injured in an on set explosion on a film set that eventually caused him to be partially paralyzed and lose his power of speech. Eventually, he recovered but later still died from a cerebral hemorrhage caused by the explosion.
* HeartwarmingInHindsight: In "Errand of Mercy", the first episode to feature the Klingons, the Organians speculate that someday, the Federation and Klingons will become allies. In ''Series/StarTrekTheNextGeneration'', we see this indeed came true, and how it happened is explored in ''Film/StarTrekVITheUndiscoveredCountry''.
** It gets better! According to ''Series/StarTrekEnterprise'', by the time of the 26th Century, the Klingon Empire will officially join as a member of the United Federation of Planets.
* HilariousInHindsight:
** Leonard Nimoy playing an emotionless alien might have been if ''InvasionOfTheBodySnatchers'' had been a bigger phenomenon than ''Franchise/StarTrek''.
** Uhura's teasing Spock in song in "Charlie X" in light of the [[Film/StarTrek recent movie.]]
** Spock once remarks that "the most unfortunate lack in current computer programming is that there is nothing available to immediately [[Series/StarTrekVoyager replace the starship surgeon]]."
** In the rejected first pilot episode, Captain Pike, Kirk's predecessor, annoyed with his crewmates, says, "What are we running here, [[Film/StarTrek a cadet ship]]?"
*** This was hilarious in hindsight as far back as ''Wrath of Khan'': the Enterprise was meant to be on a training cruise before flying off to deal with Khan and was largely full of cadets.
*** Captain Pike irritably asking Number One "are we running a cadet review?" takes on a whole new, unintended meaning in context of his role in the 2009 film.
** In "The Way to Eden" one of the female space hippies tries to seduce Sulu, who doesn't bite. And says "How do you know what I want?" with a giant grin on his face.
** ''Film/RevengeOfTheSith'' was not the first sci-fi production to have a doctor diagnose a patient with a fatal deficiency of will to live.
** Compare the older versions of Spock, [=McCoy=] and especially Kirk in "The Deadly Years" to how they really turned out.
* HoYay: Spock had so much of this with Captain Kirk that entire [[TheShipsCloset web shows]] and essays have been devoted to it, and it spawned SlashFic as a genre. But his SlapSlapKiss with Dr. [=McCoy=] shouldn't be ignored...
** It should be noted that the creator has said that Kirk and Spock's [[http://en.wikipedia.org/wiki/Kirk/Spock#Origins_and_creators.27_responses "affection was sufficient" for "physical love" "had that been the style of the 23rd Century"]]...but, I suppose that may vary?
** See the trope page itself for many, ''many'' more examples.
* IronWoobie - Spock is perfectly willing to sacrifice himself for others. He will also stand by his principles even when he expects that Kirk, [=McCoy=], or his parents will hate him for it.
* MagnificentBastard: T'Pring in "Amok Time." Vulcan marriage/divorce laws are ''very'' restrictive--betrothal from age seven, and no possibility of divorce except during the Pon Farr. As the years went by, T'Pring decided she didn't want to marry a distant, legendary figure and would rather be with a Vulcan she actually knew and liked, so she chose to challenge the marriage and chose Kirk as her champion. If Kirk one, he wouldn't want her, and she could be with Ston. If Spock won, he would still free her for bringing the challenge at all--or he would leave, and she could still be with Ston on Vulcan. Picking Kirk ensured that Ston would not die in the combat. As Spock said, flawlessly logical. Not especially ''nice'' to Kirk, but still pretty good as cunning plans go.
** Khan Noonien Singh in "Space Seed". In the briefing room, Kirk, Scotty and others discuss their secret admiration of Khan the historical figure, to the complete bemusement of Spock. They eat their words when Khan's barbarism and complete psychopathy are revealed. Even then, [=McGyvers=] follows him willingly in exile to the savage planet.
* MexicansLoveSpeedyGonzales: Scotty has a big fanbase among Scottish Trekkies.
* MyRealDaddy: Gene Roddenberry was responsible for the series as a whole, but one of his producers/writers, Gene Coon, had a great deal to do with making the show great with classic ideas like the Klingons, the Prime Directive, Khan Noonien Singh and being the series' showrunner in the first two seasons who helped many of the stories used better.
* {{Narm}} - Some aspects of the show have aged ''horribly'', especially for people born after 1990; as a result, this trope ends up popping up in places where it's obvious that wasn't the intent at all. Of course, a lot of people don't see this as a ''bad'' thing, as noted directly below.
** There are so many examples it'd be impossible to list them all, but one that stands out is the episode "The Omega Glory", in which another planet [[HollywoodEvolution evolves the American flag and constitution]], all for Kirk to make a ridiculously over-the-top patriotic speech about how [[{{Eagleland}} America is one of the best countries in the world!]] To American viewers, it's very silly but not entirely ridiculous. For non-American viewers...? Yeahhh...
*** That was a huge groan at the time. Nobody took it seriously and it was regarded as the second worst episode ever, right after "Spock's Brain".
**** Believe me, even Americans find that scene ridiculous.
** Once you're familiar with the concept of {{Redshirt}}s, it's pretty hard to take their deaths seriously. Indeed, when you're thinking, "Yup, that guy's dead" as soon as they beam down, then when the time comes it can produce chuckles.
** [[http://www.youtube.com/watch?v=Z1eFdUSnaQM Some of the fight scenes aren't quite as terrifying as they were supposed to be]].
** [[http://www.youtube.com/watch?v=UhQA-06kSLU McCoy's face at the end says it all]].
* NarmCharm - To the point where many fans decry the remastered episodes as losing much of what made the show memorable to begin with.
* NeverLiveItDown:
** William Shatner is often the butt of jokes for his {{Large Ham}} delivery that quickly alternates between drawn-out and rushed. He actually didn't get like this until the third season, where the quality of material he had to work with took a significant drop.
** Kirk's reputation as a careless manwhore. He did sleep around a lot, but if he wasn't being a male FemmeFetale, amnesiac, or mind-controlled, it was a sincerely felt attraction that failed because of the woman's death or his "marriage" to ''Enterprise''.
* NewerThanTheyThink: Though this show is Creator/GeorgeTakei's most significant acting credit, by quite a large margin, it did not spawn his famous CatchPhrase "Oh ''myyyy...''". You can thank ''Radio/TheHowardSternShow'' for that one.
* NightmareFuel: Has [[NightmareFuel/StarTrekTheOriginalSeries its own page]].
* RelationshipWritingFumble: If Kirk and Spock weren't intended to be in love with each other from day one, ''Franchise/StarTrek'' is guilty of quite possibly the greatest RWF in television history.
* SeasonalRot:
** As the show went on, the missions just kept getting weirder and weirder. Prime examples include looking for Spock's brain, a showdown at the O.K. Corral and encounters with hippies, Chicago Gangsters, Native Americans, a modern day Roman Empire, [[ThoseWackyNazis Nazis]], Abraham Lincoln and even the Greek god Apollo.
** In fact, the episode "Spock's Brain" is usually regarded as the absolute worst episode in at least the original series and sometimes in the whole of ''Franchise/StarTrek''.
** Given a LampshadeHanging in some of Kirk's in-universe biographies, which typically note that many of Kirk's reports were met with considerable disbelief from his superiors in Starfleet. The case where an alien race literally stole Spock's brain is usually mentioned in an especially disdainful manner.
* SeinfeldIsUnfunny - ''Fwoof''. TOS catches it ''bad'' these days. Not only has everyone who followed in its footsteps borrowed from it to some degree, but they've ''all'' tried to improve upon a lot of the problems the show had due to a limited budget, technological barriers of the time and the fact that the cast and crew were inventing a lot of tropes as they went. Fans who got into Trek with the newer installments can have trouble watching TOS nowadays.
* {{Shipping}} - Kirk/Spock is obviously a near-legendary example of this, with other common pairings being Scotty/Uhura (mostly in an attempt to do their romance from ''Film/StarTrekVTheFinalFrontier'' in a way that doesn't seem completely insane) and Sulu/Rand (due to the two's interactions in "The Man Trap" and the fact that Rand later wound up on the ''Excelsior'').
* [[SoBadItsGood So Bad It's Good]]:
** "[[Recap/StarTrekS3E1SpocksBrain Spock's Brain]]" is so awesomely bad that, when you approach it the right way, it becomes one of the funniest Trek episodes ever made. Rumor has it that the script originated as a prank at the expense of Creator/GeneRoddenberry. C'mon, say it, people:
--> "Brain and ''brain!'' '''What is BRAIN?!'''"
** The episode "The Omega Glory". There's something about that American flag. The Pledge and the Spock-like Satan illustration did not help. Shatner's trademark delivery worked well when he said, "Look at these words...written bigger... than the rest... tall words ... proudly saying ... 'We... the Pe... ople...
* SomeAnvilsNeedToBeDropped -- "Let That Be Your Last Battlefield." Racism is self-destructive and it makes no ''sense'' to consider people "inferior" based on purely aesthetic features.
* SpecialEffectsFailure - So many monsters... [[http://fc00.deviantart.net/fs50/f/2009/336/3/5/Yay_60__s_by_CatNipSoup.jpg and the space-dog that is clearly a dog]].
* StoicWoobie - Spock definitely falls into this category. He's an alien to two races, and several times he is injured in the line of duty, or stands by his principles under severe criticism. A few episodes that highlight this are Journey to Babel, Operation: Annihilate, and The Tholian Web.
* TearJerker: Has [[TearJerker/StarTrekTheOriginalSeries its own page]].
* TheyChangedItNowItSucks: For those who dislike the "remastered" episodes (and especially resent that CBS is obviously trying to supplant the original versions with them - though at least they aren't going [[OrwellianEditor full Lucas]]).
* TheissTitillationTheory: The TropeNamer was the series costume designer, William Ware Theiss.
* [[TookTheBadFilmSeriously Took The Bad Episode Seriously]]: DeForestKelley, an old-school character actor, made a living out of doing this, and carries on with it throughout the series, with aplomb. Contrast WilliamShatner and ''especially'' LeonardNimoy, both of whom visibly [[TheyJustDidntCare stop trying]] whenever the writing is particularly sub-par.
* UncannyValley: “Nancy” while she was stalking Rand’s salt. Creepy.
* UnfortunateImplications:
** TOS features one of the few instances of the franchise boldly going into this territory, in "The Paradise Syndrome". Kirk loses his memory, [[GoingNative goes native]] on the Planet Of The Week and falls for the GirlOfTheWeek - in this case, the natives being ''translocated descendants of Native Americans''. Yes, that's right, ''Trek'' featuring a "[[MightyWhitey mighty white man]] conquering the beautiful, suggestible native woman" story. (The natives even straight-up [[GodGuise mistake Kirk for a god]]. Yep.) It was barely acceptable when it aired, and these days is almost universally seen as an embarrassment and one of TOS' lowest points. (This was a [[SeasonalRot third season episode]], natch.)
** Not to mention the show's open sexism. In one episode the effects of a NegativeSpaceWedgie causes members of the crew to start passing out, Kirk orders them given booster shots. [=McCoy=] is later shown injecting a line of Starfleet personnel -- who are all female. Presumably tough spacemen are not in the habit of swooning. To the point of the BridgeBunnies wearing incredibly short skirts and generally having menial, unimportant roles except as background characters or the Captain's GirlOfTheWeek.
*** Although keep in mind that at the time, the miniskirt was a symbol of feminine empowerment. Yes, the short skirts were in the show as {{Fanservice}}, but that isn't the ''only'' purpose they served.
**** The fact that the Abrams reboot also features the miniskirts (and has several women in their underwear for little reason) and yet very few people seem to have got worked up about it has actually made the complaints here become rather hypocritical.
*** The original script had Mc Coy saying "Jim, I'm getting reports from all over the ship. Half the women on the ship just fainted." But in the final script, the words you heard when you saw the episode were "Half the people on the ship just fainted." Apparently that change was made very late in the game, so you still see a line of women.
** Another example was Wolf in the Fold, which involved [[ItMakesSenseInContext the spirit of Jack the Ripper feeding on peoples' fear]]. How is that sexist? Because the spirit overwhelmingly preyed on women, and Spock explicitly stated that this was because women feel fear more strongly and easily than men. (If you look carefully, the female crewmember in the foreground looks distinctly unimpressed when the line is read...)
** "Spock's Brain" features the moral that without the guidance and leadership of a strong male individual, women will inevitably become dull-witted and lazy. Notably, this episode was written under the pseudonym of "Lee Cronin" by the otherwise-talented Gene L. Coon, and rumours persist to this day that it was either a sly joke on his part or [[WriterRevolt an act of rebellion against Fred Freiberger, the newly appointed producer]].
** Perhaps the worst of all is the SeriesFinale "Turnabout Intruder," which reveals that Roddenberry's vision of an ideal, utopian future (and Roddenberry himself came up with this story, mind you) includes women being legally barred from becoming starship captains. This one was such an embarrassment to latter-day Trek that an episode of ''[[Series/StarTrekEnterprise Enterprise]]'' casually revealed that Starfleet did allow women to be captains, implying that Janice Lester's psychotic mind [[WildMassGuessing imagined that bit of oppression]].
** Though it should be noted that Roddenberry was actually ''forced'' to put in the bit about women not being allowed to command starships and did ''not'' enjoy being forced to put it in.
*** Roddenberry literally stated in a production meeting that "You’d never want to let women actually get into power. All women are cunts, and you can’t trust them." Whether or not this comment was meant as a jest or not is currently up in the air.
** In "The Return of the Archons" Kirk feels that the computer that has been running the society of Beta III is just a machine and has no soul, and that therefore there's no problem in destroying it. The crew of [[StarTrekTheNextGeneration a certain other]] ''[[StarTrekTheNextGeneration Enterprise]]'' might have a thing or two to say about that.
** In "The Changeling" there is a robot that looks very much like a Dalek that steal's Uhura's memory. The robot said that her thinking was irrational. Spock replies succinctly, "That ''unit'' is a woman." To make it even worse, when Uhura is being rehabilitated, she remembers how to speak Swahili. This have the implication that Swahili is very primitive compared to English.
*** Alternately, though, they may simply have been saying that Swahili is easier to learn than English (which isn't unreasonable, considering the high number of non-standard pronunciations in English), or they just thought it made sense that Uhura would remember how to speak her first language before remembering how to speak her second language.
*** That was Nichols' idea. Nichols thought she should be speaking Swahili, but since she didn't know any, the director thought she should deliver her lines in English. Nichols insisted that ''Uhura'' knew Swahili. They brought in a Swahili speaker to give her a few lines;[[note]] sikumbuka, "I don't remember": mbwa hii na tufe, "the dog has a ball"[[/note]] problem solved.
** Chekov's entire characterization in the original series across the films. Yeah, it's great to see a Russian Communist working with an American Capitalist - so long as the Russian is clearly inferior to his American boss and just about everyone else around him.
* ValuesResonance: Several episodes, like "A Taste of Armageddon", and most notably, "Let That Be Your Last Battlefield".
* WhatAnIdiot: Joe Tomerlin, the RedShirt who accompanied Spock down to the planet. He takes his protective glove off, puts his hand down on the surface of a planet where many people have died with no explanation, and scratches his nose with the same hand.
** Before he stabbed himself, he claimed that humanity didn't belong in space. Given his [[TooDumbToLive horrific failure to follow basic hazmat procedures]] on a space station where everyone has died for no evident cause, perhaps it was only ''he'' that did not belong in space.
* TheWoobie - Apollo in ''Who Mourns for Adonais''.
** Alexander in "Plato's Stepchildren", after being used for centuries as Parmen's ChewToy.
** Spock is seen as this by many fans.
** [=McCoy=] has his woobie episodes in "The Empath" and "For The World Is Hollow And I Have Touched The Sky".
** Chekov. While every one of the main cast gets into their fair share of trouble, it always seems to pull at your heartstrings a bit more when it happens to poor adorable Chekov. Additionally, the BigBrotherInstinct Kirk seems to feel towards him is rather d'aww-inducing, [[CrowningMomentOfHeartwarming particularly the way Kirk calls him by his first name when he's been hurt.]]
** Yeoman Rand. Of the first four episodes aired, three of them had her having to fend off unwanted male attention (though the first one of them was actually a shapeshifting alien, as if that makes it any better for her.)
