->"''Well, that's it, then -- you had a [[FreudianExcuse controlling mother]] who had certain expectations, and [[LonelyRichKid 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. This kind of supression is almost always temporary and always 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. At worst, the character will be put in a sort of UncannyValley, being human in appearance but not human in behaviour. Any sort of permanent Emotion Suppression will probably turn out this way, BonusPoints if it is not voluntary.

When a character has been emotionally hurt previously, or seen someone close to them be hurt, they may decide to seek SafetyInIndifference.

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, well, emotionless or lets you get rid of certain emotions.

[[folder: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 don't take it and freely indulge their emotions and senses.]]
* The Soviet 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. Did not end well: the entire race almost died out because of no desire to love and procreate.

[[folder:Literature]]
* ''Literature/{{We}}'': people of the [[{{Dystopia}} One 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 ''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 SergeyLukyanenko's ''{{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.
* 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 ''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 {{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.

[[folder:Live Action TV]]
* The [[Franchise/StarTrek 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.
* Vampires in ''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.

[[folder:Tabletop RPG]]
* ''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]].

* ''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]].
* ''[[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.
