->''"Take nothing on its looks; take everything on evidence. There's no better rule."''
-->-- '''Mr. Jaggers''', ''Literature/GreatExpectations''

''"[[TheKirk Captain]], the logical course of action in this situation is to let the inhabitants of [[SugarBowl Pupolon]] fend for themselves. We need the [[MacGuffin device]] keeping the planet's orbit stable, or risk endangering the very existence of TheFederation. I am aware of [[TheEndOfTheWorldAsWeKnowIt the consequences]] for the local population, [[TheMcCoy Doctor]], but simply rushing in to '[[SaveThePrincess save the]] [[TheHighQueen high priestess]]' will leave us open to a [[ProudWarriorRaceGuy Klingon]] [[InescapableAmbush ambush]] with a [[LudicrousPrecision 78.52% probability]] of [[TotalPartyKill outright destruction]].\\\
I realize [[SadisticChoice this is a hard choice]], [[TheCaptain Captain]], but [[TheNeedsOfTheMany the needs of the many must outweigh the needs of the few.]]"''

A character who will always think before acting, The Spock is an archetype that can be loosely summed up as the tendency to apply rules, reason and the greater good to all of his/her decisions. This character can exist by themselves, but more often, they will have [[TheMcCoy a more emotional and humanistic counterpart]] to contrast their decisions. The main difference between the two archetypes is that while TheMcCoy will leap before looking, The Spock's solution to problems will have a balanced and well-thought out approach.

The Spock's relationship with his crewmates[=/=][[TrueCompanions comrades]] is often tense, because this character type is willing and able to ruthlessly consider ethically troubling situations without batting an eye -- especially situations where [[WeHaveReserves people might be ordered to die]]. While his counterpart TheMcCoy is interested in doing the right thing regardless of cost, The Spock is more interested in the end result. For him, everyone ([[TheNeedsOfTheMany including himself]]) is expendable and he has no problem treating people as such.

The Spock maintains audience sympathy by being willing to TakeAThirdOption and also by being as ruthless about his own life as the lives of his crewmates, if not more so. Even better, he is [[StiffUpperLip utterly unflappable]] in the face of serious problems or danger; his friends know that no matter how terrifying or hopeless things get, he will [[NervesOfSteel never lose his cool]] and will not stop working on a solution to save everyone. He will not have a problem hearing TheMcCoy's side of things, though.

When put in a PowerTrio with TheKirk and TheMcCoy, he becomes the superego in UsefulNotes/IdSuperegoAndEgo. The Spock will at times become a TinMan, though this varies with the writing, and will often have NoSenseOfHumor. When he has emotion, he may sometimes express it with a FascinatingEyebrow and nothing more. Since SmartPeoplePlayChess, if The Spock plays a game, it will invariably be [[VariantChess a variant of chess]].

Closely related to TheStoic, AgentScully, EmotionlessGirl, and LittleMissSnarker. Often becomes a StrawVulcan, but occasionally ends up on the winning side of EmotionsVsStoicism. Probably sides with the Enlightenment in RomanticismVersusEnlightenment. {{Well Intentioned Extremist}}s often come across similarly when they believe they're working for the greater good. See also SpockSpeak.

This character type is ShootTheDog personified.

Named (obviously) for Spock from ''Franchise/StarTrek''. Compare their eternal opposite, TheMcCoy.



[[folder: Anime and Manga]]
%%* "D" from ''Anime/DualParallelTroubleAdventure''.
%%* Hoshino Ruri from ''Anime/MartianSuccessorNadesico'' is both The Spock and a LittleMissSnarker.
%%* Nagato Yuki from ''LightNovel/HaruhiSuzumiya''.
%%* Keith Anyan from ''Manga/TowardTheTerra''.
%%* Lumiere from ''Anime/KiddyGrade''.
* All Contractors in ''Anime/DarkerThanBlack'' are said to be like this; part of their condition is that they always act rationally and with their own best interests in mind, dismissing emotional attachments. Throughout the series several counter-examples are shown, to the degree that whether the statement is actually true is up for discussion.
* Inspector Lunge from ''Anime/{{Monster}}'' is a subversion. He is an unemotional workaholic, but he makes most of his decisions based on his {{Pride}}, and, because of it, he disregards mounting evidence of Johan's existence until it becomes overwhelming. A true Spock would have impartially re-evaluated evidence and circumstances as they changed and based his judgements purely on logic. Also, his [[spoiler: big fight with Roberto]] shows that he does have an emotional BerserkButton, and while his [[spoiler: handcuffing himself to Tenma after being badly wounded]] is [[TheDeterminator admirably badass]], it could hardly be called a rational decision.
%%* Exedore/Exsedol from the ''Anime/{{Macross}}'' and ''Anime/{{Robotech}}'' universes, though he has his emotional moments, too.
%%* Fate from ''Manga/MahouSenseiNegima'' is a villainous version of this.
%%* Paul von Oberstein from ''Anime/LegendOfGalacticHeroes'' is a good example of this trope.
* ''Anime/{{Hyouka}}'': Houtarou Oreki. He's an intelligent, clever, stoic young man.
* ''Manga/DeathNote'': L is a surprisingly good one. There's a minor deviation in that he sometimes informs people of his emotions, even though he doesn't display them unless the situation's truly dire. Near also qualifies. Mello? [[HotBlooded Not at all...]]
* Ulquiorra from ''Manga/{{Bleach}}'' appears to be a villainous example of this trope- while his comrades generally act like children, he openly describes himself as an emotionless tool for [[BigBad Aizen]] to use as he pleases. The closest he ever comes to showing emotion are several cases where his eyes slightly widen and a single instance where he raises his voice.
%%* Wilhelmina in ''LightNovel/ShakuganNoShana''. There was even an episode called "Heartless Wilhelmina".
* Sai from ''Manga/{{Naruto}}''. He was raised in ROOT, which means he has no emotions whatsoever. Although he gets better at understanding them later when he joins team 7.
** Tobirama Senju, aka the 2nd Hokage, is also this, especially compared to his [[TheMcCoy older brother the 1st]]. He always advocates taking the most logical action in the face of a conflict, [[GoodIsNotNice even if said action is callous and/or ethically questionable]]. Whether the story is sympathetic to this varies and can be anywhere between JerkassHasAPoint and UnwittingInstigatorOfDoom.
* Kyoya from ''Manga/OuranHighSchoolHostClub''. He deliberately crafts a hardened, purely logical exterior, and gets pretty annoyed/confused when people (Tamaki, Haruhi) see through it. He's the one really running the club and making all the real decisions - slightly subverted, though, in that nobody fights him on his decisions since he never has to make life or death choices.
* C. C. from ''Anime/CodeGeass'' is a particularly [[DeadpanSnarker snarky]] variant, at least while the cold side of her SugarAndIcePersonality is the one being shown. Far from being emotionless, she has very strong feelings, she is just able to keep them under control most of the time.
%%* Natarle in the ''[[Anime/MobileSuitGundamSeed Gundam Seed]]'' Power Trio.
%%** She would fire missiles at an ally Gundam, knowing its armor would survive the hit, for the chance of hitting the enemy.
* Rossiu of ''Anime/TengenToppaGurrenLagann'', whose otherwise [[StrawmanHasAPoint reasonable actions]] in an [[ScrewTheRulesIHaveSupernaturalPowers unreasonable setting]] makes him WrongGenreSavvy and thus totally obsolete.
%%* [[EmotionlessGirl Rei Ayanami]] and [[HotScientist Ritsuko Akagi]] of ''Anime/NeonGenesisEvangelion''.
%%* Seto Kaiba from ''Anime/YuGiOh''.
* Piccolo of ''Anime/DragonBallZ''…sometimes. He first appears as a raving, cackling lunatic hell-bent on killing Goku (justified, as he has all his [[BigBad father's]] memories, and is only [[PsychopathicManchild a few years old.]]) Then he mellows, is shown meditating in a lotus position, becomes an [[AntiHero Anti-Hero]], and voila. Also, he's arguably the most intelligent character on the show. Sometimes, though, he gets angry. Like if [[MoralityPet Gohan]] [[BerserkButton gets hurt.]] Then he goes from being The Spock to a PapaWolf.
* Fuu Hououji of ''Manga/MagicKnightRayearth'' is an unusual example. She is much more calm, observant, and thoughtful than [[TheKirk Hikaru]] and [[TheMcCoy Umi]] , but she also applies her logic to a strong sense of compassion and attempts to comfort her friends.

[[folder: Comic Books]]
%%* Brainiac 5 of DC's ''Comicbook/{{Legion Of Super-Heroes}}''.
%%* Metron of the ComicBook/NewGods who was explicitly based on Spock.
* ComicBook/TheVision of Marvel's ''ComicBook/TheAvengers''. No wonder, he's a robot after all. Partially averted on times, DependingOnTheWriter: he may show human emotions to a high or low extension, or lack them completely.
* Dr. Manhattan of ''ComicBook/{{Watchmen}}'', who is referred to as "goddamn Mr Spock there" by a minor character at a cocktail party.
* Taken to epic levels in ''ComicBook/FinalCrisis: Superman Beyond'' with the CompositeCharacter Captain Allen Adam, A.K.A. the Quantum Superman of Earth 4, who is a meshing of the Good Doctor with the original ComicBook/CaptainAtom. Even when on heavy drugs to keep his quantum senses in check he's capable of feats of extreme mental prowess, and after his drugs fade off he attains a state of nigh-omniscience and arranges the activation of the Cosmic Armor that saves all of reality from an EldritchAbomination that eats stories. Only The Spock can stay calm and babble about the organic nature of TheMultiverse while the UltimateEvil emerges.
* ''{{Franchise/TheTransformers}}'':
** Prowl, more so in the comic (which is why it's here). IDW's take [[DeconstructedTrope deconstructs]] this- Prowl's lack of empathy and IDidWhatIHadToDo attitude alienate him from the rest of the Autobots, even those who were previously his friends. During ComicBook/TransformersRobotsInDisguise and ComicBook/TransformersCombinerWars, it's show that his "logical" behavior isn't even that logical- he's motivated as much by a desire for revenge and lingering mental instability over his torture by the Decepticons and being made a part of Devastator.
** Shockwave, though he's a villain. Typically it's considered his strength, as he can remain emotionally detached and not get distracted like Megatron or Starscream are prone to doing. Subverted in IDW's ''Spotlight: Shockwave'', when he's unable to figure out a logical reason for why the Dinobots attacked him and begins losing the fight, only to realize that their reason is illogical: they're after revenge and he's only able to turn the fight around by deliberately activating an illogical [[TheBerserker rage mode]].
* Skalman in ''ComicBook/{{Bamse}}'' is almost an example, but he is usually even less likely to suggest a course of action that seems unethical - in fact, it is sometimes shown that being logical and thinking things through allows him to do the opposite.
* James-Michael of ''ComicBook/OmegaTheUnknown'', due to his [[spoiler: being raised by robot protectors]].
* The Treen of ''ComicStrip/DanDare'' are completely emotionless and driven by logic. Sondar, a good Treen, is capable of feeling emotion, but still approaches problems logically.
* While he's the self-styled leader of the ComicBook/FantasticFour, Reed Richards is most comfortable as the thinker of the group. If anyone is TheKirk it's his wife Sue.

[[folder: Fan Works]]
* ''Fanfic/AdviceAndTrust'': Rei always tries to be logical and rational. Her mindset is: logic makes things clearer and simpler. And thanks to that mindset she starts out to break Gendo's control upon her. She was being ordered to take a bunch of pills whose purpose was turning her into an emotionless doll. Asuka and Shinji warned her that her medication regimen was hazardous to her health. She researched, and her research proved Asuka was right. Ergo, Rei stopped taking her medication.
* ''Fanfic/HarryPotterAndTheMethodsOfRationality'': Harry is too young and emotional to be TheSpock, but he sees it as an ideal, and always tries to ignore his emotions and make decisions based on pure logic. Occasionally a bit of a deconstruction, as his "purely rational" decisions often come across as cold or even cruel, and may be leading him to [[spoiler: become a dark lord.]] For Example, [[spoiler: when he rationalizes that killing a unicorn to extend Quirrel's life is no worse than killing a cow to eat, even though his gut instinct tells him not to.]]
* ''Literature/TheSpectrumGame'': Inigo is a rare OnlySaneMan variant. While he does get angry easily, it takes him quite a lot to get him to act on or express his anger. He is a coldly logical StepfordSmiler and StoicWoobie who definitely comes off as calmer than his teammates.

* ''Film/ReservoirDogs'' - Mr Pink is the most logical of all the crew, especially when he acts as the {{foil}} to [[TheMcCoy Mr White]]. The first scene shows him refusing to throw in money to tip the waitress, giving his reason as to why. He is later distrustful of everyone, and disgusted that Mr White gave Mr Orange his real name and hometown, considering anybody, even the dying Mr Orange, could be the rat. [[spoiler: Not only is he right about everything, but he is the only character to survive the film.]] Subverted in that Mr. Pink is anything but cool--he's both logical and wildly neurotic.
* Dr. Egon Spengler from ''Film/{{Ghostbusters 1984}}''. In the [[Film/GhostbustersII sequel]], he says that his parents did not believe in toys and he seems to be nigh-immune to the mood slime which makes the two most "positive" Ghostbusters try to kill each other. In the commentary for the original film, [[WordOfGod Harold Ramis]] notes that he deliberately played Egon as a Spock-like character. He also notes that there is only one scene where he actually shows emotion, when Walter Peck tries to have the Ghostbusters arrested for an explosion that he caused himself.
** For the record, Egon was affected by the mood slime in the {{novelization}} and script of the movie. He was, however, the first to overcome its effects.
* Juror #4 (the stockbroker with wire rim glasses) from ''Film/TwelveAngryMen''. He's one of the longest holdouts against Juror #8, but unlike #10, who is motivated by bigotry, or #3, who is projecting his family issues onto the case, #4 is simply not convinced by the circumstantial logic that #8 offers as reasonable doubt and sticks to the defendant's inability to remember the movies he claimed to see. He only changes his vote when #8 quizzes ''him'' on the last double-feature he saw and he's unable to remember basic details himself, proving that the defendant's claim is plausible after all.
* ''Film/{{Sunshine}}''. When the crew out to save the sun (and the world) are down to five members and their oxygen supply is cut, they realize they only have enough oxygen for four people to make a return trip. Michelle Yeoh doesn't bat an eyelid in suggesting they murder one of their own (whom happened to be already wracked with guilt for a mistake that led them into this predicament in the first place) instead of all five of them dying from lack of oxygen, and it didn't take much convincing for two other crew members to accept the idea.
* ''Film/{{The Avengers|2012}}'': Iron Man fits TheKirk, and Captain America fits TheMcCoy. Black Widow being the most calculating and logical of the group would fit TheSpock.
** Although in terms of Iron Man and Captain America alone, these two show a different dynamic with Steve being TheSpock. He is the tactician of the team and less of an ideological hero than he was in his own movie, while Tony is clearly dismayed at how calm he is following [[spoiler:Coulson's death]] and has a moment where he wins Bruce over through sheer compassion.
* Abe Sapien in ''Film/{{Hellboy}}''; very logical and curious, abide to the rules and always thinks in the greater good [[spoiler:if not [[HellboyIITheGoldenArmy in love with a Elven Princess]] that is]]. He also seems fascinated by the things he study.
* CLU from ''Film/TronLegacy'' was programmed by Flynn to work as a Superego for the Grid: his creator's lack of foresight, however, has made him grow into a dysfunctional one, obsessed with perfection at the expense of flexibility.

* Ivan of ''Literature/TheBrothersKaramazov''.
* Elinor Dashwood, the protagonist of ''Literature/SenseAndSensibility'', in contrast to her sister [[TheMcCoy Marianne]]. Possibly the TropeMaker, considering this is one of the first known intentional uses of it (Austen intended the sisters' EmotionsVersusStoicism to be a metaphor for RomanticismVersusEnlightenment). Also one of the few examples where The Spock is right, and TheMcCoy has to learn to be more reserved rather than the other way around.
* Death in the ''Literature/{{Discworld}}'' series. Is attempting to understand the human race, but is finding it...difficult. At times he seems to know a bit more about human nature than he lets on though, so maybe it's just an act.
* Voort "Piggy" saBinring from ''[[Literature/XWingSeries Wraith Squadron]]''. He's a PigMan from a species more known for violent aggression and stupidity, but brain tampering made him into a GeniusBruiser, GoodWithNumbers and tending to be logical and calm. We see a bestial side exactly once, and it takes getting gut-shot to bring it out. Sort of similar to Vulcans, who practice emotional suppression precisely because their emotions are so violent and difficult to control compared with other species.
* The Mentats in the ''Franchise/{{Dune}}'' series.
* Michael Valentine Smith from Creator/RobertAHeinlein's ''Literature/StrangerInAStrangeLand''. He is capable of feeling overwhelming emotion, but when he does, he simply slips into a coma until he's found a way to logically respond to the situation. As a human raised on Mars, it takes him quite a while to understand laughter, grief, fear and loss - his only emotions at the start of the book are curiosity and love.
* C.S Forester is fond of this. The captains in ''The Good Shepherd'' and ''The Captain from Connecticut'' were very extreme Spocks. HoratioHornblower was a slightly more mild version but still something of a Spock.
* Asher in ''Literature/SomeoneElsesWar''.
* ''Literature/TheDresdenFiles''
** Mab to the extreme, in contrast with her sister Titania, who is TheMcCoy. Mab is utterly ruthless and pragmatic in pursuit of her goals [[spoiler:of protecting reality from the [[EldritchAbomination Outsiders]].]]
** However, Mab is also TheMcCoy to her mother, Mother Winter, the ultimate pragmatist. Mother Winter calls Mab a softy because [[spoiler:Mab won't kill Mab's own daughter Maeve when Maeve has become a traitor. Mab has just enough emotion and humanity left to find herself incapable of acting as she knows she should.]]
* Arthur Conan Doyle's Literature/SherlockHolmes is the UrExample. [[AloofBigBrother Mycroft]] could be seen as this, too.
* Bean of the ''Literature/EndersGame'' series. The International Fleet is looking for the best student to command their entire navy, and the two runners-up are Bean and Ender. Eventually it becomes clear that though Bean is as smart as Ender and more ruthlessly logical ([[spoiler:due to having been genetically altered for greater intelligence]]), Ender is the more effective commander because he empathizes and associates with his sub-commanders and troops. As a result, Ender's soldiers have greater morale and willingness to follow their leader into deep battle than Bean's, turning the advantage in Ender's direction even with identical commands.
* Stannis Baratheon from ''Literature/ASongOfIceAndFire'' is a stern, pragmatic {{Determinator}} in contrast with his [[TheId lazy, drunken elder brother Robert]] and his [[TheEgo ambitious younger brother Renly]].

[[folder: Live Action TV]]
* [[TropeNamer Spock]] from ''Series/StarTrekTheOriginalSeries''. Creator/GeneRoddenberry went on record saying that Spock is an idealized version of himself, as he'd always bemoaned his own passionate and hot-tempered nature.
-->'''Spock:''' I realize [[SadisticChoice this is a hard choice]], [[TheCaptain Captain]], but [[TheNeedsOfTheMany the needs of the many must outweigh the needs of the few.]]
** Almost every other Vulcan of Franchise/StarTrek also falls into this trope, including Tuvok from ''Series/StarTrekVoyager'' and T'Pol from ''Series/StarTrekEnterprise''. In fact, among Vulcans the half-human Spock ends up being TheKirk or even TheMcCoy by comparison.
* Like TheKirk and TheMcCoy, there's some GenerationXerox between the different series. Consider:
** Data from ''Series/StarTrekTheNextGeneration''. {{Subverted|Trope}}, though, in that Data is actually aspiring to become more human, and makes significant strides toward that throughout the show and its films. Still, as Spock himself put it:
---> '''Spock:''' Fascinating. You have an efficient intellect, superior physical skills, no emotional impediments... there are Vulcans who aspire all their lives to achieve what you've been given, by design.
** Dax originally had shades of this in ''Series/StarTrekDeepSpaceNine'' (this is lampshaded in a time travel episode where she unknowingly parrots Spock's statistical readings), but grew organically into a party girl and textbook case of ImmortalImmaturity. The acerbic security chief, Odo, is much closer to this.
** Seven of Nine from ''Series/StarTrekVoyager'', though she tries to overcome this in later parts of the show.
* ''Series/GameOfThrones'': Jorah's pragmatism makes him this to Barristan's [=McCoy=] and Dany's Kirk.
* ''Series/{{Sherlock}}'': Sherlock, Moriarty, Magnussen and Mycroft are this, definitely. The ''only'' way to get Sherlock pissed is to hurt Mrs. Hudson or threaten John's life, though.
* Cristina Yang from ''Series/GreysAnatomy''.
* Strangely enough, for all the jokes of his lack of intelligence, this is usually the role Jayne Cobb plays in ''Series/{{Firefly}}''. Ruthlessly pragmatic, Jayne will always be the first one to suggest that the smartest course of action when in a bind would be to betray this person or abandon that cause. Rarely is his logic on these matters ever called into question, but no one else is willing to be that cut-throat.
* Temperance "Bones" Brennan from ''Series/{{Bones}}''. This becomes funny given that another character called "Bones" from Star Trek is the original [[TheMcCoy McCoy]]. Also, Zack Addy.
* Teal'c of ''Series/StargateSG1'' is sometimes The Spock, in that he has the same unflappability and (usually) rational thinking, though he's more TheStoic than a person who actually doesn't experience emotion (several episodes demonstrate he experiences emotions quite intensely, especially in relation to his family and in relation to his cause of freeing [[SlaveRace his people]]).
* Ficus in ''Series/{{Quark}}'' is a parody of The Spock taken to extremes. He's a sentient plant and has absolutely no emotions, taking everything logically and speaking only in SpockSpeak.
* ''Series/{{Farscape}}'':
** Aeryn Sun is a minor tactical genius and ''never'' loses her cool...perhaps to her detriment, as the path of her [[OfficialCouple relationship with Crichton]] is rocky and convoluted. She becomes more TheKirk as she goes along.
** Sikozu and, after his HeelFaceTurn, [[spoiler: Scorpius]] are perhaps the purest Spock members of the crew,having a tendency to be coldly pragmatic about problems.
** Rygel is a slight subversion, as he has a tendency to on occasion claim his actions are for the best of the crew as a whole, but more often than not he's just being a greedy self-interested JerkAss. He has his moments, however.
* Sheldon in ''Series/TheBigBangTheory''. Lampshaded, as Sheldon considers his circle of friends one doctor short of a landing party, and has proclaimed himself the Spock. Sheldon might not be a full-fledged example of this trope, though. He's too [[ItsAllAboutMe self-centered]] to be detached from the situation, so to speak - but Leonard's mother, Beverly, fits this trope very well.
* Freddie on ''Series/ICarly'', opposite to Carly (TheKirk) and Sam (TheMcCoy).
* Moze on ''Series/NedsDeclassifiedSchoolSurvivalGuide'', with Cookie as TheMcCoy and Ned as TheKirk.
* Doctor Larry Fleinhart from ''Series/{{NUMB3RS}}''. Surprisingly, Doctor Charlie Epps doesn't qualify, as he emotes just fine. More surprising as Larry is the [[RomanticismVersusEnlightenment Romantic]] one and Charlie is the [[RomanticismVersusEnlightenment Enlightened]] one.
* Castiel the doubting angel from ''Series/{{Supernatural}}''.
* Rupert Giles in ''Series/BuffyTheVampireSlayer''. Subverted, as he is often flustered or baffled, but forces himself to adhere to the cold-headed British persona he was raised to believe was most proper for any occasion.
* House in ''Series/{{House}}''.
* Cameron in ''Series/TerminatorTheSarahConnorChronicles''. While she can emulate emotion, she usually goes the most coldly pragmatic route.
* Jor-El in ''Series/{{Smallville}}''. He often cooks up options for Clark to beat the bad guy that involve sacrificing his friends. He is however, prone to getting royally pissed at Clark for refusing to listen to him.
* Dr. Moira Isles from ''Series/RizzoliAndIsles''.
--> '''Rizzoli:''' You'd tell me if you were a cyborg, right?
* Hauser in ''Series/{{Alcatraz}}'' is a rather unpleasant version of this trope.
* Jack Harkness from ''Series/{{Torchwood}}''. Interesting, in that he was TheKirk to the Doctor, originally.
* Clayton Webb, but even more so Sturgis Turner, fills this role in ''Series/{{JAG}}''.
* ''Series/{{Scandal}}'': Olivia.
* Kerr Avon from ''Series/BlakesSeven'' is a rather cynical version.
* Robert [=McCall=], Series/TheEqualizer, is very much this but has tempered it some on his own by choosing to stick to ideals he had put away for the greater good when he was part of [[GovernmentAgencyOfFiction The Agency]]. He always prefers logic, rationalism, and hard facts to intuition, and never lets his emotions rule instead of his head, always calculating and manipulating the odds, and willing to pay the cost himself to save someone's life.
** Also, Control from the same series, the only person in the series to out-Spock [=McCall=] and to whom [=McCall=] could look like a [[TheMcCoy McCoy]] next to.
* Kane is this on ''Series/{{The 100}}'', always putting the rules of the Ark and TheNeedsOfTheMany ahead of everything else. However, he seems to recognize that sometimes a more warm-hearted approach is needed; he just can't provide it himself, and so prefers acting as second-in-command rather than TheLeader.
** Lexa is another example. She believes that [[LoveIsAWeakness love (and emotions in general) are a weakness]], and is ruthless about sacrificing anyone, even herself or those close to her, if she believes it's what's best for her people.
* The Robot in ''Series/LostInSpace'', of course it helps that is a robot, yet in the series has artificial intelligence and is capable of having emotions, so the cold logic he uses most of the time is a choice.
* In ''Series/BabylonFive'':
** Ivanova among the crew, especially to Sheridan's TheKirk, Ivanova is very logical and detached and follows the rules strictly most of the time, though she does have some private outbursts. Contrast with much more emotional and intuitive Garibaldi as TheMcCoy.
** Kosh among the ambassadors, a cold, cryptic super-advance alien worried only for the big scheme of things and coming from an entire race based on cold discipline and order. He can be very frustrating for Sheridan because of this, and he’s imply to be the most emotional of his specie.
** The SpinOff show ''Series/{{Crusade}}'' has the techno-mage Galen as this. Galen is cold and logical and can be very ruthless. He can act irrationally though as [[spoiler:when he kidnaps the ship in order to fulfill his dead wife's last wish.]]
* Professor Arturo in ''Series/{{Sliders}}'' is clearly The Spock of the group. Arturo is cold, logical and always put first the ethical action (especially regarding the alteration of the universe they visit) over the well being of the other characters and himself. When JohnRhysDavies left the show his ReplacementScrappy Maggie Beckett kept more or less the same role as a cold-hearted military-trained character that often thinks in survival than anything else.

[[folder:Mythology and Religion]]
* [[UsefulNotes/ClassicalMythology Hades]] is usually portrayed as the unemotional ruler who wouldn't allow exceptions to the rules of the Underworld.

[[folder:Newspaper Comics]]
* Linus often performs this function for Charlie Brown in ''ComicStrip/{{Peanuts}}''. Likewise Schroeder to Lucy (and occasionally Charlie).

[[folder:Tabletop Games]]
* Alchemical ''TabletopGame/{{Exalted}}'' have a trait called "Clarity" that tracks how much of this personality they accumulate; as they grow in Clarity, they become increasingly focused on pragmatic and efficient solutions and will place lower priority on compassionate activity, at the cost of becoming increasingly less emotional and having difficulty relating to other people (they also have some Charms that can harness Clarity to grant increased cognitive ability). Clarity is reduced by prolonged meaningful interaction with normal human beings (or, in the case of some Alchemicals, immersion in memories from their [[PastLifeMemories past lives]]).
* ''TabletopGame/{{Warhammer 40000}}''
** Among the Primarchs, there was Ferrus Manus on the Imperial side and Perturabo among the traitors. Both tended to be the most dispassionate and calculating Primarchs, and their Legions followed suit - although Perturabo's claim is a little weakened by his towering [[TheResenter resentment]] and susceptibility to [[MoodSwinger brief spasms of uncontrollable fury]].
** Adeptus Mechanicus supporting character tends to be this to whatever Inquisitor, Space Marine or Imperial Guard protagonist they follow around, especially if they have had the cybernetic surgical procedures of Clear Thoughts, excising the parts of their brains capable of emotions.
* In ''TablietopGame/MagicTheGathering'', White and Blue often play this role, with White focusing on social structures and Blue on logic and reason.

* A rare main character example: Brutus from Shakespeare's ''Theatre/JuliusCaesar'', with either Cassius or Antony as TheMcCoy. A quiet, (literally) stoic, cool-headed intellectual who is a friend of Caesar's but is willing to do him in since, to quote the TropeNamer, the needs of the many outweigh the needs of the few. ("Not that I loved Caesar less, but that I loved Rome more!")
* In Shakespeare's ''Theatre/TroilusAndCressida'': Ulysses on the Greek side, with Agamemnon as TheKirk and Ajax as a fairly thickheaded variation on TheMcCoy. On the Trojan side, Hector fills this role, to Priam as Kirk and Troilus as TheMcCoy
* In ''Theatre/RomeoAndJuliet'', Benvolio is this to Romeo, with Mercutio as TheMcCoy.

* [[AnIcePerson Kopaka,]] the resident [[TheStoic Stoic]] in ''Toys/{{BIONICLE}}''.
* Franchise/{{Transformers}}: Almost all versions of Shockwave are what you get when this type of character is a villain. Cold, calculating, and unflinching. The [[ComicBook/TheTransformers original comic version]] even decided to overthrow Megatron, because it was the logical thing to do. And later on, he handed back power to Megatron, again because it was perfectly logical for him to do so. Best encapsulated by this quote from [[ComicBook/TheTransformersMegaseries another Shockwave]]:
-->'''Shockwave:''' Ultimately, I serve only one master: Pure logic.

** The [[MultipleChoicePast Ruthless background]] [[PlayerCharacter Shepard]] also qualifies, doing whatever it takes to get the job done, no matter how horrific, and usually in the middle of the action himself--the military's go-to guy for the most vital and most morally compromising missions. The Renegade [[KarmaMeter morality path]] also comes off as this in all the major decisions and in many of the conversations (with the rest of the time consisting of being a hardass, and in some instances in the first game, a bit of a xenophobe as well)
* Squall of ''Videogame/FinalFantasyVIII'' is a rare main character version. [[ChildSoldiers Raised as a mercenary]], he's cynical about how the world works and tries to act solely according to duty rather than emotion. For the first portion of the game he seems like a lone Spock in a team of [[TheMcCoy McCoys]], but much of his CharacterDevelopment is him learning how to healthily feel and express his emotions rather than acting like an automaton until he blows a gasket over, say, the execution of someone he knew from childhood.
* Stern, the Material of Wisdom in the ''VideoGame/MagicalGirlLyricalNanohaAsPortable'' games. Funnily enough, this made her the kindest one amongst the [[HumanoidAbomination Materials]] and the first one to make a HeelFaceTurn away from their OmnicidalManiac side since she came to the logical conclusion that mindlessly destroying everything is stupid.
* Jade Curtiss of ''VideoGame/TalesOfTheAbyss'', despite his StepfordSmiler outward persona, fits this trope when it comes down to actual decision-making. It's a CrowningMomentOfHeartwarming the one time that he does admit he'd rather not do the most coldly logical thing, [[spoiler:which would be to ask Luke to sacrifice himself rather than Asch]].
* Jusqua of ''VideoGame/FinalFantasyThe4HeroesOfLight'' thinks that he's this. When Horne is petrified, he doesn't go with Brandt and Yunita because they can find a way to lift the curse. Later, [[SubvertedTrope he faces up to the fact]] that he was actually being immature by snarking at them when he himself was unwilling to try anything he thought he'd fail at.
* ''VisualNovel/DanganRonpa'' has Kirigiri, who is coldly aloof, calculating, and emotionless. Celeste is one as well, what with her saying they should abandon all attachment to the outside world and just accept their fate living in Hope's Peak [[spoiler: though ultimately subverted when it's revealed that she's so desperate to get out that she orchestrates a double murder.]] Togami is a milder, crueler version.
** ''VisualNovel/SuperDanganRonpa2'' introduces Izuru Kamukura, who makes all of the above look hotheaded. [[spoiler:He used to be a perfectly ordinary guy, until he accepted to subject himself to an operation in order to become as talented as the other Ultimates. The end result: he acquired ''every'' talent, but his memories and emotions are completely gone and he has no drive other than acquire other talents]].
* The Orpheans in ''VideoGame/XenobladeChroniclesX'' are an entire race of these. While they can feel emotions, they mostly keep them in check in favor of finding the most efficient solution to their problems through pure logic.
** Maurice Chausson always puts the needs of NLA above the needs of any individual person [[spoiler:even to the point of leaving his own son on Earth]]. The only reason he shows Team Elma preferential treatment is that they're just [[TheAce so damn good at their jobs]] that losing any of them would be equivalent to losing 20 other [=BLADEs=].

%%* Chou Yaru in ''Webcomic/UnicornJelly''.
* Vaarsuvius from ''Webcomic/TheOrderOfTheStick'' ''tries'' to be this in order to become more effective and overcome a great obstacle, but seeing as how the elf is anything but emotionless and is in fact haunted by the memory of a great failure, the result is disastrous.
%%* Theo from ''Webcomic/GoldCoinComics'' is like this...usually.
* Zombie/Narrator/.../whatever you want to call him plays this pretty straight in ''Webcomic/HannaIsNotABoysName''
* Quinn-Tain in ''Webcomic/{{Harkovast}}'' bases his decision only on what he thinks is necessary to win the war. Emotional concerns are always [[http://www.drunkduck.com/Harkovast/index.php?p=702277 secondary]].
* Mr. Raven in ''Webcomic/ElGoonishShive''.
** Susan as well. Her GoodAngelBadAngel ImagineSpots even take the form of herself as a Franchise/StarTrek Vulcan when she's trying to think logically.

[[folder: Web Original]]
* The [=AI=] Delta from ''Machinima/RedVsBlue'' is logic personified. [[LiteralSplitPersonality Literally]]. Ironically, Delta is probably the most humane of the various Freelancer [=AI=]s, despite his noticeably incomplete understanding of human nature.
* In the ''[[Roleplay/GlobalGuardiansPBEMUniverse Global Guardians]], Achilles is the The Spock, and is also the team leader. Guardsman is TheKirk, while Arachne and Ultra-Man are TheMcCoy.
* Lady Ink from ''WebOriginal/TheBookOfStoriesOCT''. Of course, she is a personification of order and structure, so it makes sense.
%%* Dr. Gears of the Wiki/SCPFoundation
* ''Website/FlameWarriors'': Android, who is emotionless and only notes illogic in other flame warriors' arguments.
* ''WebAnimation/{{Dreamscape}}'': Kai (TheSpock), Eleenin (TheMcCoy), and Drake (TheKirk); the three stoic human protectors of the planet.
** Kai is TheSpock/Superego because he is a stickler for taking the most logical approach to things, and pushes those who are reluctant to follow through to do so anyway.

[[folder: Western Animation]]
%% ''WesternAnimation/StarTrekTheAnimatedSeries'' has Spock in this role, of course.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Twilight Sparkle takes this role in the first two episodes, not caring about "pointless" things like friends or fun. [[CharacterDevelopment She ends up coming around at the end of the second episode]], and the rest of the season documents her learning about just how kick ass friends are. She occasionally lapses into this when academic subjects are mentioned, especially magic. She has a very logical, scientific view of the world and though her excellent education means that she's often right, it does leave her rather inflexible. Her tendency to dismiss information that she finds illogical in particular has been called on more than once.
** Celestia, the BigGood of the series, more than once put the main cast (whom she is said to treasure) in a dangerous position with a gentle smile, sometimes without telling them so. Of course, given her position and age it is somewhat expected...
** Wind Whistler filled the role in ''WesternAnimation/MyLittlePonyAndFriends''. Her use of logic over emotion leads the other ponies to joke that she has no feelings, which does [[DidYouThinkICantFeel hurt said feelings]].
** Among the Cutie Mark Crusaders, this is usually Apple Bloom's position. She is a well-grounded hardworking filly like her big sister Applejack and has little problem with emotional matters (though there are exceptions; in which case this role likely falls to Sweetie Belle).
%%* [[{{Fembot}} Big Brain]] from an episode of ''[[Franchise/CareBears Adventures in Care-a-Lot]]''.
%%* Marsala from ''WesternAnimation/ExoSquad'', even though others of his species are generally much more emotional than he is.
%%* Sokka from ''WesternAnimation/AvatarTheLastAirbender'', so much so that he comes into conflict with the rest of the group.
%%** Similarly, Mako from ''WesternAnimation/TheLegendOfKorra''. Especially in comparison to [[TheMcCoy Korra]].
%%* Braniac 5 from the ''WesternAnimation/LegionOfSuperHeroes'' usually fits this trope. As does the Martian Manhunter.
%%* Tommy Anybody from ''WesternAnimation/MrBogus''
* Dr. Egon Spengler continues to be as Spock-like in ''WesternAnimation/TheRealGhostbusters'' cartoon as he was in the films, going so far as to remind a space station full of Star Fleet [[{{Expy}} Expies]] of an old colleague.
-->'''Egon:''' ''(after delivering a stream of TechnoBabble)'' Fascinating.
-->'''[=McTavish=]:''' Are you sure you've never served as a science officer?
* Batman in ''WesternAnimation/JusticeLeague'' and ''WesternAnimation/JusticeLeagueUnlimited'', often portrayed as emotionless, cold, logical and ruthless to some extend. Of course, is in many ways part of the image that he himself wants to present.
* In the Christmas cartoon ''WesternAnimation/TwasTheNightBeforeChristmas'', the mouse Albert plays this role and proves to be the main antagonistic force, even if it's ''very'' unwittingly -- the mouse kicks off the short by writing a letter proclaiming Santa isn't real, signs it "All of Us" and has his entire hometown removed from Santa's delivery since it was published in a newspaper.
* In ''WesternAnimation/RainbowRangers'' Bonnie Blueberry is smart like a computer, and doesn't understand silliness or practical jokes.

[[folder: Real Life]]
* Dr. Herman Kahn. His works in the 1950s on nuclear war examine the aftermath in extremely dry terms. He was considered a sort of monster by some to actually argue that, while extremely horrible, a nuclear holocaust would not be the end of humanity.
* Within the PowerTrio of the Allied leadership of UsefulNotes/WorldWarII, UsefulNotes/JosefStalin played the Spock to [[UsefulNotes/FranklinDRoosevelt FDR's]] [[TheKirk Kirk]] and UsefulNotes/WinstonChurchill's [[TheMcCoy McCoy]]. When you're a dictator who sees himself as just [[IDidWhatIHadToDo doing what it takes]] to ensure your country's survival (occasionally even half-admitting being NecessarilyEvil), it sort of comes with the territory.
* Admiral Raymond A. Spruance, especially when compared to the tendency of his friend [[RedOniBlueOni Red Oni]] Admiral William F. Halsey to pull the LeeroyJenkins.
* Introverted Thinkers on the UsefulNotes/MyersBriggs scale are stereotypically considered to be this. "Does it work?"
* Has a pretty firm footing in [[http://en.wikipedia.org/wiki/Alexithymia alexithymia]].
* By his own admission, Ehud Barak, one-time Prime Minister and repeat Defense Minister of UsefulNotes/{{Israel}}, and one of the best generals in the [[UsefulNotes/IsraelisWithInfraredMissiles IDF]]'s history. He and everyone around him quite frankly states that Barak's mind is like a steel trap: remorselessly methodical and logical, remembering everything, and expecting everyone to be just as logical as he. Barak, however, does have the humanity to admit that this is something of a double-edged sword: his logical method blinded him to the emotions of others, particularly the Palestinian and Syrian diplomats he tried to negotiate with at Camp David in 2000. This insensitivity--again by his own admission--probably cost him the deal of the century.
* The leopard, in comparison to other big cats. Lacking the [[ThePowerOfFriendship teamwork]] of [[TheKirk lions]] or the [[LightningBruiser raw strength]] of [[TheMcCoy tigers]], leopards rely on a combination of cunning, versatility, and calculated risk to survive. They are opportunistic hunters that carefully judge their prey before attacking, and actively avoid confrontation with stronger competing species.
