->''"Well, that's it, then -- you had a controlling mother who had certain expectations, and if you strayed from them, you were shut down. That's why you're afraid to care about anything -- and why you can't express yourself."''
-->-- '''Azula''', summing up her friend Mai on ''WesternAnimation/AvatarTheLastAirbender''

Human emotions can be quite an obstacle. [[PrimalFear Fear]] can make you unable to face the danger. Compassion can prevent you from [[ShootTheDog shooting the dog]] even if it's necessary. Love can make you [[LoveMakesYouCrazy crazy]], [[LoveMakesYouDumb dumb]] or [[LoveMakesYouEvil lead you straight to the Dark Side]]. Let alone [[LoveHurts it hurts]]. And then there are such things as anger or hatred. Anyway, emotions cloud your mind and [[StrawVulcan impede logical thought]].

So, what do you do with them? Well, in the world of fiction you can find a way to relieve yourself of this burden. Via some sort of [[CharlesAtlasSuperpower training]] or some AppliedPhlebotinum you can completely remove your capacity to feel emotions. Results and consequences depend on [[AuthorTract the author]] and how exactly the emotions are suppressed.

Portrayed as a good thing, Emotion Suppression can be used to enter HeroicSafeMode, to escape MindRape or simply to concentrate on the fight clearing your head of unimportant thoughts. The SmartGuy may enter a state of pure impartial logic to perform AwesomenessByAnalysis, and the master of PolitenessJudo can calmly [[SilkHidingSteel suggest to the ambassador that it would be wise for his kingdom to withdraw their invading troops before the Fantasic Nukes are launched]] without dropping her polite and reserved facade for an instant. More combat or magically oriented characters likewise can benefit from a MeditationPowerup. This kind of suppression is almost always temporary and voluntary.

Sometimes it is portrayed as a bad thing. In that case the character in question [[StealthPun can at best hope]] to be an [[LonersAreFreaks a loner]] or an EmotionlessGirl not knowing ThisThingYouCallLove. Alternately, when a character has been emotionally hurt previously, or seen someone close to them be hurt, they may decide to seek SafetyInIndifference, and often need time before they [[PowerOfTrust feel comfortable letting down their guard again]]. At worst, the character will be put in a sort of UncannyValley, being human in appearance but not human in behaviour- arguably the worst form being the StepfordSmiler. Any sort of permanent Emotion Suppression will probably turn out this way, especially if it is not voluntary.

On the neutral side, Emotion Suppression is often portrayed as a form of PowerAtAPrice: a character's SuperPoweredEvilSide may demonstrate TranquilFury or take the [[PragmaticHero pragmatic]] approach to solving problems, or TheEmpath may have to practice Emotion Suppression to prevent PowerIncontinence. Occasionally a hero must also remember that GoodIsNotSoft or [[GoodIsNotNice Nice]], and that they may be occasionally called upon to set aside their personal feelings ForTheGreaterGood when solving a ColdEquation.

This trope can also be carried out on a massive scale. There can be a human or alien culture where every representative has their emotions supressed. This situation also has little chance of being undeniably good. At best, (other) humans will just leave it as it is, perhaps after [[StrawVulcan some demonstrations of how emotions can be useful]]. If it's done by an EvilOverlord or... uh... [[BigBrotherIsWatching a caring and benevolent ruler]] who is unable to [[GettingSmiliesPaintedOnYourSoul paint smilies on their subjects' souls]] but at least wants to remove tears from there, you've got a ready [[{{Dystopia}} dystopian]] setting.

This is part of the basis of {{The Stoic}} and the {{Emotionless Girl}}, {{Ice Queen}} and {{The Quiet One}} characters, {{The Baroness}}, the {{Deadpan Snarker}} (and {{Little Miss Snarker}}), the {{Broken Bird}}, the SugarAndIcePersonality and the {{Aloof Big Brother}}. Compare and contrast GettingSmiliesPaintedOnYourSoul or {{Lotus Eater Machine}}: EmotionSuppression does ''not'' make you happy, it just makes you not-sad, not-angry, you know, ''emotionless''.


[[folder:Anime and Manga]]
* Sai from ''Manga/{{Naruto}}'', being a member of a special ANBU branch, has undergone a training that removed his emotions. It also left him with NoSocialSkills.
* In ''Manga/RanmaOneHalf'' the emotional suppression technique "Soul of Ice" is needed in order to generate a cold BattleAura, which is a vital component in the "Hiryu Shoten Ha" CounterAttack technique.
* Seta Sojiro from ''Manga/RurouniKenshin''.
* This forcefully happens to Satoru Suzuki in ''LightNovel/{{Overlord}}'' when he becomes Momonga, his {{lich}} video game character, as the undead cannot feel emotions. This is both a good and a bad thing. While he does not feel emotions like fear, disgust or rage which could cloud his mind, he also [[LackOfEmpathy loses his empathy]] and becomes completely inhuman.
* In the ''Anime/AngelBeats'' manga, Yusa voluntarily undergoes this.
* Mob from ''Manga/MobPsycho100'' suppresses his emotions to prevent his PsychicPowers from going haywire and hurting the people around him. When he first met Dimple, the latter mocked him for his stunted emotions until he couldn't hold back his Rage any longer and, well...
-->'''Mob''': They came out upon your request. [[SuperMode These are my emotions.]] [[CurbStompBattle This is what happens when I let them show.]]
* In ''Manga/OnePiece'', [[spoiler: Sanji's brothers Ichiji, Niji and Yonji had their ability to feel and understand empathy surgically removed by their AbusiveParent Judge ''while in utero'', [[TykeBomb so he could weaponize them]]. They mother Sora took a gene modification-reversing drug to save her sons, but for some reason the drug only worked on Sanji. The other three have just a tiny shred of humanity left, which up until now has only showed once: when the three guys [[EvenEvilHasStandards freaked out]] over [[EvilMatriarch Big Mom]]'s [[AndIMustScream "living library"]].]]

[[folder:Comic Books]]
* To deal with her life, Maika from ''ComicBook/{{Monstress}}'' appears to experience no emotions besides hunger and rage. It's unclear - even to her - whether her other emotions are gone or just suppressed.
* In ''ComicBook/{{Runaways}}'', Nico once magically stripped Klara of her emotions in an attempt to rein in her powers, which were going haywire as the result of Klara suffering a panic attack. in the short term, this worked out sort of okay, but in the long term, it turned Klara into even more of a nervous wreck.
* One arc of the "threeboot" ''ComicBook/LegionOfSuperheroes'' saw several of the Legionnaires trying to lead a RagtagBunchOfMisfits against a well-organized team of supervillains. In an effort to boost their chances, Saturn Girl used her powers to suppress the misfits' ability to feel fear.

* Enforced upon all Psyches in Psychelia (including Empath) in ''Fanfic/EmpathTheLuckiestSmurf''. Even information about emotions is suppressed.
* ''Fanfic/AdviceAndTrust'': Rei has been unwittingly doing this to herself with various pharmaceuticals until Asuka and Shinji find out and convince her to stop.

* ''Film/{{Equilibrium}}'' takes place in a society where everyone uses a drug called Prozium to suppress their emotions. Refusal to administer it is [[{{Dystopia}} punishable by death]]. [[spoiler:Hypocritically, the higher-ups [[ScrewTheRulesIMakeThem don't take it]] and freely indulge their emotions and senses.]]
* The Soviet film ''Film/TeensInTheUniverse'' features a planet where robots driven by [[AIIsACrapshoot crapshoot AI]] decide to make all people "happy" by removing most of their emotions. People are forced to undergo this operation with a form of MassHypnosis. It did not end well: the entire race almost died out because of no desire to love and procreate.
* ''Project Itoh: Genocidal Organ''. The {{Super Soldier}}s have B.E.A.R (Battle Emotion Adaptive Regulation) enabling them to stay calm in combat conditions and kill without remorse. The plot involves the soldiers hunting a linguistic expert who's developed a [[LanguageEqualsThought language of genocide]] that he claims works in a similar manner to B.E.A.R by repressing the conscience, [[HatePlague enabling ordinary people to commit atrocities]].

* ''Literature/{{We}}'': People of the [[OneWorldOrder One]] [[{{Dystopia}} State]] are calculating, emotionless and strive only to follow only logic. In the end [[spoiler:a way is discovered to truly erase an individual's ability to feel emotions by [[PhlebotinumDuJour irradiating a certain spot of the brain with X-Rays]] and everyone is irreversibly brainwashed.]]
* ''The Chronicles of Grimm Dragonblaster'': The titular character has to repress his emotions using dangerous addictive drugs in order to confront a demon mage who draws magic from negative emotions, renedering him emotionless and logical.
* Philip Jose Farmer's ''[[http://en.wikipedia.org/wiki/The_Other_Log_of_Phileas_Fogg The Other Log of Phileas Fogg]]''. In this retelling of ''Literature/AroundTheWorldInEightyDays'', Phileas Fogg is actually an agent of an alien race. His habitual reserve is due to a mental ability to shunt aside negative emotions so he can act normally.
* In Creator/SergeyLukyanenko's ''Literature/{{Genome}}'' the specs (specialists who are [[BioAugmentation genetically augmented]] for certain jobs) have certain emotions suppressed and others modified as part of their specialization.
* "Dissociation" in ''Literature/{{Strata}}'' is a type of meditation with this effect.
* In Patrick Rothfuss's ''Literature/TheKingkillerChronicle'', Kvothe learns a mental exercise called "Heart of Stone" which places the practitioner in a state of dispassionate calm where all other emotions are temporarily shunted aside. [[ForgottenPhlebotinum Which he then doesn't use for the three years he needed it.]]
* The telepaths in the ''Literature/FirebirdTrilogy'' possess this ability. However, the stronger the emotion, the harder it is to completely suppress; only the best telepaths are truly capable of controlling all their emotions. The suppression is completely voluntary; it is generally used to ignore painful or unhappy emotions.
* In Max Barry's ''Literature/MachineMan'', Dr. Charles Neumann is not very emotional to begin with. However, after [[spoiler: mapping his emotional responses with an MRI, he suppresses any traces of guilt or regret. Chemically.]]
* Jedi in the {{Franchise/Star Wars Expanded Universe}} are expected to be able to suppress their emotions in order to think clearly; in practice it depends.
** [[http://starwars.wikia.com/wiki/Dengar Dengar]], a man TheEmpire [[WeCanRebuildHim rebuilt as an assassin]], had his emotions surgically cut away, all but anger, despair, and hope, as those would be useful to an assassin. Hope is the driving force, the hope that if he does well enough they will restore him to his old self. They also accidentally left him the ability to feel loneliness. Interestingly, when they ordered him to assassinate children, he left Imperial service- he wasn't able to ''feel'' why it was wrong, but he could still logically recognize that it was [[WouldntHurtAChild not something he wanted to do]]. He did get what he wanted, sort of, in the end; a woman who used cybernetic implants to share sensation and emotion fell in love with him and was able to partially restore him after they were married. Everyone but her still found him rather cold, though.
** In ''Rebel Force'' there's an Imperial who's developed brainwashing techniques to similarly create assassins, though without surgery, and it's repeatedly said that these assassins are without any emotion at all, though they can convincingly [[CrocodileTears fake any]] while infiltrating on the way to a target. The best of them, X-7, finds while tracking Luke Skywalker that anger is returning to him.
* In one of the early ''Literature/{{Shadowrun}}'' novels, the protagonist seeks help from a criminal she'd been involved with a few years before. He reveals he's been taking an EmotionSuppression drug non-stop ever since she dumped him; as he's been on it so long, he doesn't dare stop taking it because several years' suppressed feelings all at once would be too painful to catch up on.
* ''Literature/RealQuickFlashFic'' has a story where a murderer is using meditation to try to supress his emotions; not with the greatest of success.
* A spell in the ''Literature/NightWatch'' 'verse has a temporary effect like this. Known as the Bureaucratic Rat, the spell creates a construct that seeks out the target (like a real rodent) and bites it. The bite temporarily disconnects the person from all emotions. Since the Others' magic is tied directly to their emotions, the bitten is unable to use magic for about an hour, until the effect wears off. As a side effect, the person also tends to indulge in SpockSpeak, hence the "bureaucratic" part of the name.
* ''Franchise/DocSavage'': The primary weapon of the villain in ''The Men Who Smiled No More'' is a drug that prevents its victims from feeling emotion. This makes the victim's very suggestable, and also capable of committing casual murder as they cannot see anything wrong with the act.
* In ''Literature/ThePillarsOfReality'', the Mages teach their people to suppress all emotion (and indeed, that everything to which someone might emotionally react is just an [[TheTreacheryOfImages irrelevant illusion]] anyway). Alain starts to lose this when he's forced to interact with someone outside his Guild, though he still remains TheStoic.
* In ''Borderline'' by Mishell Baker, one magic-practicing character casts a spell to create a temporary familiar made up of all her cast-off emotions, that usually takes the form of a small, ghostly dragon-shaped spirit. When she does so, she becomes an EmotionlessGirl, but all her feelings return when the spell ends. This makes it easier to do her job and cope with a variety of stressful situations, since she has PTSD from some very bad things that happened in her childhood, but the spell is very draining and makes it difficult for her to perform any other kind of magic while it is active. Nearly everyone in this book would benefit from it, since all the main characters have some kind of mental illness and a history of traumatic events in their pasts, and the protagonist, who has borderline personality disorder, is both awed and deeply envious when she sees the other character cast a spell to temporarily split off her emotions from the reasoning part of her mind.
* Nezumi in ''Broken Gate'' has done a ''very'' extreme version of this, as she disregarded anything not related to guarding the gate, in which case, she cut off her own thoughts and feelings, emotions included, turning her into an EmotionlessGirl who could no longer feel nor express them.
* The society of the Grey Men from the ''Literature/TheStainlessSteelRat'' series by Creator/HarryHarrison includes indoctrinating their youth into being totally emotionless. In ''The Stainless Steel Rat Wants You!'', the hero finds the home planet of the Grey Men; he describes an eerily quiet classroom full of schoolchildren (no smiling, no laughter, no gum-chewing), with two posters on the wall reading "DO NOT SMILE" and "DO NOT FROWN".
* ''Literature/WeAreLegionWeAreBob'': Since most strong emotions come from glands, which are simulated for the replicants anyway, replicants are fitted with an endocrine suppressor program to keep them from feeling much more than "deep concern." Bob removes it soon after he leaves Sol, but turns it back on for battles.
* ''Literature/JourneyToChaos'': Ordercrafters face this as an occupational hazard because the source of their power, Order, is a god without emotion. The longer they are ordercrafters and the more they use their power, the more their emotions are suppressed until they can't feel anything at all. They have ways of managing this, such as aid from a chaotic deity.
* The ability to suppress or control one's emotions is a common ability in the ''Literature/{{Dune}}'' series, often as a result of training and meditation. The most famous example is the Litany Against Fear, a SurvivalMantra whose associated mental exercises are used by the Bene Gesserit order to suppress fear.

[[folder:Live Action TV]]
* ''Franchise/StarTrek'': The Vulcan culture has EmotionSuppression at its core.
* In ''Series/{{Farscape}}'', Crichton spends the first half of season 4 taking drugs which are intended to [[ItsNotYouItsMyEnemies suppress his love for Aeryn]]. She's... not happy when she finds out.
* The ''Series/{{Chuck}}'' episode "Chuck vs the Tic Tac" revolves around an emotion-suppressing pill called the Laudenol, which military soldiers used to take to be stronger warriors in battle. Casey was blackmailed into delivering it to his former commanding offer to save the life of his ex-fiancée. Towards the end of the episode, Chuck swallows the pill and it unleashes the full power of the Intersect (due to Chuck's feelings always getting in the way) allowing him to dispatch an entire army of goons in less than a few seconds.
* Vampires in ''Series/TheVampireDiaries'' have the ability to turn off their emotions, presumably to stop things like guilt getting in the way of their hunting. Apparently, this ability fades after a few centuries. In the first season finale [[spoiler: Jeremy attempts to become a vampire so he can shut off his grief.]] In the third season [[spoiler: Klaus compels Stefan into turning his off so he'll stop resisting his orders.]]
* In ''Series/DoctorWho'' The Cybermen have no emotions because they have them removed when they get changed; in the past series, this was due to being subsumed by the Cyberman HiveMind system practiced by Cyber-Controllers and Cyber-Planners, and in the new, it is done through emotion-nulling firmware. Breaking them out of this ends with the Cyberman writhing in horrific pain as ''everything'' they've ever denied rushes into them.
* ''Series/TheMagicians2016'': Battle magic requires cold focus to be used reliably--without excessive training, it comes in fits and starts. However, hedge witches sometimes use a loophole: They literally bottle up their emotions, turning themselves into deadpan automatons but allowing them to easily use battle magic. The problem is that when you stop bottling up your emotions, you get hit with all of them at once, and it hits '''hard'''. The main characters end up collapsed in their rooms crying for hours.


[[folder:Tabletop Games]]
* ''TabletopGame/CallOfCthulhu'' supplement ''The Asylum and Other Tales'', adventure "The Asylum". One of the drugs Doctor Freygan has developed is called Mood Flattener. It temporarily suppresses all emotion in the recipient, whether positive or negative.
* ''TabletopGame/{{Warhammer 40000}}'': Many factions. The [[SuperSoldier Space Marines]] and the [[DeathSeeker Death Corps of Krieg]] actually have cybernetic augments that pump emotion-dulling drugs through their bloodstream. The [[OurElvesAreBetter Craftworld Eldar]] do this through training alone, [[EasyRoadToHell and they need to otherwise their souls will be claimed by Slaanesh]].

[[folder:Video Games]]
* ''VideoGame/PokemonDiamondAndPearl'': Cyrus, leader of the Team Galactic, is trying to create a universe with no emotions so that there would be no conflicts.
* In ''VideoGame/CreepyCastle'', Darking intend to use a device called the Heartbreaker which removes emotions to achieve world peace.
* ''VideoGame/DigitalDevilSaga'' has Gale, who stubbornly tries to remain an [[EmotionlessGirl Emotionless Guy]] even though he keeps having intense hallucinations wracked with emotions he can't explain. [[BewareTheNiceOnes When he finally explodes, the results are not pretty]].
* The ''Franchise/DragonAge'' series has "the Tranquil": mages who have been entirely cut off from the Fade in order to prevent demonic possession. However, this not only robs them of their use of magic but also renders them entirely emotionless. Tranquil retain their memories of their former selves and remain independent thinkers, but they lack any form of emotional response whatsoever, not only stuff like happiness or fear but even boredom. Reactions in-game are mixed. Some characters are horrified by the procedure. Others consider that if the alternatives were demonic possession or execution, becoming Tranquil was preferable. Asking the Tranquil themselves what they think gets the predictable response that they don't mind what they've become, but by definition the state they are in renders that answer meaningless.
* Tatsuya's scenario in ''VideoGame/{{Persona 2}}: Eternal Punishment'' reveals Izanami, in the Kadath Mandala, wears a mask that crushes her emotions. When questioned, she reveals that though her fury at being abandoned by Izanagi in Yomutsu Hirakasa has faded, her ''sorrow'' has not, and thus she keeps the mask on until she can be with Izanagi once more.
* ''[[VideoGame/WorldOfWarcraft World of Warcraft]]'' has an odd case where a character does this to himself. According to legend, Emperor Shaohao expelled his negative emotions from his body (thus creating the Sha) in order to save Pandaria from the Shattering.
* [[VideoGame/{{Touhou}} Koishi Komeiji]] was tired of being a Satori, a race of {{Youkai}} with extremely powerful mind-reading abilities, so she shut close her third eye. This thankfully sealed her mind-reading, but had the unforeseen side effect of shutting down her ability to read her ''own'' mind as well, taking her personality and emotions with it.
* In ''VideoGame/FinalFantasyVI'', Shadow tells Terra Branford that there are many people like him who have killed their emotions and warns her against forgetting that, implying that he thinks she'd be wise to not do the same.

[[folder:Web Animation]]
* A positive example in ''WebAnimiation/{{RWBY}}''. Ren's Semblance temporarily calms the negative emotions of himself and anyone he happens to be touching. Since [[AnimalisticAbomination the Grimm]] are attracted to such emotions, they are unable to sense him while it is active, even if they're looking straight at him.

* Magus of ''Webcomic/ElGoonishShive'' has a "Calm" spell [[http://www.egscomics.com/index.php?id=2423 that suppresses emotions.]] He uses it to [[spoiler: keep Ashley from panicking after he possesses Elliot and kidnaps her. [[http://www.egscomics.com/index.php?id=2426 Bluntness is a known side-effect]]]]
* ''Webcomic/GirlGenius'': Suppressing emotions that are dangerous distractions in the moment is part of a Smoke Knight's training, they have to do so consciously however and if the thing they were emotional about has lasting repercussions like the death of a friend they can be emotional about it later.
-->'''Varpa:''' Smoke feels nothing.

[[folder:Western Animation]]
* ''WesternAnimation/TeenTitans'': Raven has to constantly suppress her emotions lest she lose control of her powers completely. Hence the meditation.
* In an episode of ''WesternAnimation/{{Fairly Odd Parents}}'', Timmy wishes to have emotions removed and stored in a box. This effectively makes him completely fearless and popular, until he realizes that it's not so great if you don't have any emotions to enjoy it with.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': In the episode “[[Recap/MyLittlePonyFriendshipIsMagicS7E2AllBottledUp All Bottled Up]]”, after Trixie accidentally teleports Twilight’s enchanted map table to who knows where and spends most of the episode making light of it despite the potential for it to get Starlight into a great deal of trouble, Starlight deals with her mounting anger with Trixie by magically siphoning off her negative emotions into a bottle whenever it seems like she might lose control. This works fine, until the bottle breaks.
