A gadget which firmly attaches itself to a character, and thereby attaches said character's behavior in service to the plot. Implicit in the Restraining Bolt are both its unremovability and the desire of the "bolt-ee" to remove it posthaste.

A Restraining Bolt usually has an ethos distinctly different from that of its carrier, and the ability to impose that ethos on him when they have a difference of opinion. If the difference isn't too great, or is one mainly of magnitude rather than type, the Bolt and its "owner" can sometimes come to some manner of compromise. Such compromises, though, are never sure things. In science fiction, it's fairly common for the Mascot or TeamPet to in fact be an example of the monsters that the team usually fight, with a RestrainingBolt attached as a means of taming them.

In stories that employ FunctionalMagic, the Restraining Bolt is a "{{Geas}}" -- a magical compulsion. A particularly strong or willful EmpathicWeapon can act as a Restraining Bolt on its user.

Bolts are not limited to any given morality or side, and seldom are the ethical implications of these devices explored. At least [[MoralDissonance they aren't so long as the good guys are the only ones using them]].

If the Bolt exists just to power the character up when it's removed, it's IAmNotLeftHanded.

One common example of a Restraining Bolt is ICannotSelfTerminate. A common technological equivalent is the MoralityChip. Compare with PowerLimiter. Also see ExplosiveLeash, ShockCollar, PowerNullifier and SupernormalBindings. An ObstructiveCodeOfConduct is a voluntary Restraining Bolt.

Named for the droid control devices from the ''Franchise/StarWars'' movies.

!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* The cursed seals placed on members of the Hyuuga branch family in ''Manga/{{Naruto}}'', these act as a traditional restraining bolt in that they stop members of the branch family from harming (or in some cases thinking about harming) members of the head family, so that they remain a servant clan to the head family. And it also stops the devastating advanced bloodline of the Hyuuga family from getting into enemy hands, by sealing away the Byakugan when the wearer dies.
** Later, it is revealed that Sai (and every other member of his black ops division) possesses another kind of Restraining Bolt, one that prevents him from disclosing any information about his boss. If he does, then the curse mark will paralyse him (and thus, render him unable to speak). [[spoiler:It's been confirmed that all ROOT members' tongue seals vanished at the time of Danzo's death.]]
* ''InuYasha'': Kaede forces Inuyasha to wear a magical, non-removable necklace she created that is controlled by a trigger-word spoken by Kagome. Whenever Kagome uses the trigger-word ("Sit, boy!"), the necklace's enchantment painfully forces InuYasha to the ground (at times with enough force to crush wooden bridges or crater earth). Early in the series, she uses this ability in self-defense and to enforce morality on the MadeOfIron half-demon, but later on it is invoked less frequently until she eventually stops using it all together. In the anime, it's used much more frequently, and its use never fully dies off because it's used for comedy.
** In the 3rd movie, a collision of several powerful forces actually breaks the necklace, causing it to fall apart into its component beads. Since the movies are not officially canon, however, the ResetButton is duly pressed in the final scene and the necklace goes back on, even though by that point it's no longer necessary.
** His sword Tessaiga. Without it (if it's separated from him or if it breaks), Inuyasha's demon half sends him into an UnstoppableRage and turns him into a mindless monster. Tessaiga was made so that this wouldn't happen to him (and the sword's a lot better than what he'd get for letting his demon half take over).
* ''Anime/MazingerZ'': It was implied in the original series and outright shown in ''ShinMazingerZero'' that Z has a Restraining Bolt: its pilot. If Mazinger lacks a pilot to control and restrain its power, it can became a demon and destroy the world. ''{{Mazinkaiser}}'' showed if the HumongousMecha is not controlled, it simply goes berserk and destroys all it meets. ''ShinMazingerZero'' elaborated further on this, showing that [[spoiler:if it is not piloted or it is piloted by someone is dominated by negative emotions (sadness, hurt, fury, hatred, helplessness...), Mazinger-Z evolves into an EldritchAbomination and destroys the world.]]
** Minerva-X's circuit partner. Without it, she would be unable to tell friend from foe and would go berserk.
* The armor worn by the HumongousMecha in ''Anime/NeonGenesisEvangelion'' serves the dual purpose of protective gear and Restraining Bolt.
** Apparently it keeps the Evas from going berserk and killing everything, and instead forces them to obey orders from the pilots. Given that the Evas are the ultimate weapons, [[spoiler:with minds of their own, and a very bloodthirsty inner nature]], it's a fair notion. Although Unit-01 tends to go berserk whenever she feels like it anyway, and eventually is the one to break her armor off.
*** Imagine you made a [[spoiler:clone of a physical god, then you surgically removed a portion of its spinal column]] to allow someone of your choice to control its actions, to use it in a war against [[spoiler:its own kin]]. It is at least borderline sentient and quite aware of what you're doing during this process. Now imagine just how important keeping said [[spoiler:physical god]] restrained would be. How far does this go? Their power source is missing, specifically so that if it gets out of control they can pull the plug and let the batteries run down. [[spoiler:Oh, and don't ask about what happened to the originals, you won't like the answers. The first action taken by one when it has a limitless power supply is to break said restraints and allow itself to be hauled back into its cage, grinning with the knowledge that it is effectively unstoppable now.]]
** ''RebuildOfEvangelion 2.0'' modified this a bit. Unit 02 has literal restraining bolts below the [[VerticalMechaFins fins]] and along its back. When Mari removes these... '''holy shit'''. If berserk means "uh oh", Beast mode means "OH FUCK!!!"
* ''[[GaoGaiGar GaoGaiGar Final]]'' had the villains capture the main character and implant a mind-controlling Restraining Bolt that did, in fact, look like giant bolts.
* In ''Anime/CodeGeass'', Lelouch is given the power to [[CompellingVoice give others an absolute order]] [[HypnoticEyes which they cannot disobey]], essentially whatever type of Restraining Bolt he likes. He theorizes that if someone is given an order that they find completely repugnant or badly against their true nature, they could resist it a little, as seen when [[spoiler:he accidentally orders his half-sister Euphemia to "kill all the Japanese" and she resists at first, but eventually gives in.]] Merely ordering someone to kill himself or herself is ''not nearly sufficient'' to invoke this; the order has to be truly against the very nature of the person in question.
** The final episode offers a little more proof for Lelouch's theory: [[spoiler:He orders his sister-turned-opponent Nunnally to hand over the controls to the KillSat Damocles. She fights it for about a minute before the Geass wins out and she hands it over with a cheerful smile on her face, and after the effects wear off, she's beyond upset at what happened.]]
** Best display of this is the geass that Lelouch gives to Suzaku to [[spoiler:"Live"! Suzaku is highly suicidal and tries to get himself killed in many dangerous situations. Due to his geass he is unable to allow himself to die which results in his nuking of Tokyo settlement]].
* The titular demon of the manga ''{{Nora}}'' has a habit of coming up with various iterations of "(His) Ingenious Plan" to take the remote control for his particular bolt from the boy to whom he's been bound. Most of these are single-step plans involving things like [[RocksFallEveryoneDies dropping rocks on the kid]] while he's asleep or making him fall into hastily-dug holes. Since Nora's 'victim' is a MagnificentBastard-in-training, it's safe to say that FailureIsTheOnlyOption.
* After her first appearance, Victoria in ''FrankenFran'' has a chip put in her head that jolts her severely if she gets violent. Fran, her "sister" and the person who put the chip in there, has hopes that it will teach the kill-crazy Victoria to appreciate life. The odds of that are pretty low.
* Moka's titular Rosario in ''RosarioToVampire'', as well as Tsukune's holy lock in the manga.
* ''KamenNoMaidGuy'' has a [[SubvertedTrope subversion]]; Naeka is given a Maid Guy Whistle, which causes Kogarashi unspeakable pain, and aside from prolonged beatings is the only way to control him. She breaks it first thing next episode.
* Demons in ''ChronoCrusade'' are often subject to geas cast on them by their masters. It first shows up when Lerajie is contracted to Azmaria's foster father, but uses Azmaria's powers to break free from it. Later in the manga, it's revealed that Pandaemonium has the ability to cast geas on demons [[spoiler:because their horns connect them to her. Aion and the rest of the sinners tear out their own horns to keep themselves from being controlled by her.]]
* The School Curse thingy that Evangeline is under in ''MahouSenseiNegima'' doubles as a power limiter in sealing her magic power and (apparently) the majority of her shinso powers as well. But as for this trope, it forces her to attend a middle school full of... well, full of Negima characters. And also prevents her from causing chaos. The only way for her to get free is if A. Nagi breaks the curse B. The principal constantly signs forms to let her leave campus, letting her automatically regain her powers C. The school barrier is destroyed, which is generally far too difficult to take down to be practical. Even though it happens at least twice. She doesn't get her magic unless she stops being a jerk.
** Actually the School Curse prevents her from leaving the Mahora campus, and the school barrier limits her powers (its purpose is to limit the powers of any monstrously powerful being on campus, and Eva qualifies). The school barrier has been shut down twice in the manga, once during a power maintenance black-out, and again as part of Chao's scheme. Eva didn't take advantage of the second instance.
*** That we know about or that has yet become apparent. During the "bad future" period, it's commented in the manga that she's out of Chachamaru's detection range. She certainly had most of a week for vacation time, and had knowledge of and exploitable access to some of the time travel methods used in that arc.
* Senri's [[EyepatchOfPower eyepatch]] in ''Manga/PlusAnima'' acts as a restraining bolt
* Also used in ''{{Saiyuki}}'' by those members of the team who need them (although they do gain more power making it partly IAmNotLeftHanded)
* The [[http://en.wikipedia.org/wiki/Tachikoma Tachikoma]] walking tanks in ''GhostInTheShell'' have a literal restraining bolt covering their chin-mounted projectile weapons, which can only be removed by human(oid) personnel. As far as the trope is concerned, said bolts are artifacts of the numerous physical and procedural limitations placed on the Tachikomas, given that they're ''just'' smart enough to get into trouble.
* Similarly, ''Macross'' introduces this trope in its [[MacrossFrontier newest incarnation]]. In ''MacrossPlus'', the BigBad protected itself by hijacking the [[LightningBruiser Ghost X-9]] AttackDrone prototype. In the later ''Macross Frontier'', Luca's AIF-7S drones are equipped with a "Judah System" that slaves the drones to his ELINT Valkyrie, essentially rendering the drones into a remote-controlled appendage. When he disengages the system in the final battle [[OhCrap in response to the enemy]] [[GodzillaThreshold deploying Ghost V-9s]], the drones turn into {{Flash Step}}ping {{Lightning Bruiser}}s and proceed to ''open a can'' on the Ghosts.
-->'''Luca:''' [[ICallItVera Simon, John, Peter]]... I will now unlock your chains. ''(cue RapidFireTyping)'' Show the power that once [[MacrossPlus plunged Macross City]] [[ContinuityNod into the depths of terror]]! Judah System, '''RELEASE!'''
* During the FRLG arc of ''PokemonSpecial'', [[BigBad Giovanni]] shows that he is CrazyPrepared as he ''claimed'' that he didn't expect Mewtwo to show up and try to kill him, but he apparently always brings around with him a special suit specifically meant to restrain Mewtwo and limit its massive power.
** The suit was identical to the armor that anime!Giovanni made anime!Mewtwo wear in ''PokÚmon: The First Movie.''
* In ''Anime/ShinMazinger,'' Baron Ashura and several of Dr. Hell's other minions were modified to never attack Dr. Hell or his assistant. Viscount Pygamon promptly bypassed this by gouging out his own eyes.
* All inmates of the titular ''DeadmanWonderland'' are fitted with a collar that contains multiple devices to ensure obedience to the prison. This forces criminals of all sorts to participate in deadly contests and humiliating shows to avoid death by a poison being injected into them.
* In ''Manga/TheWorldGodOnlyKnows'', Keima's primary motivation for capturing the loose souls is to prevent the collar around his neck from exploding and killing him. In order to do that, though, he must make women fall in love with him in order to get them out of hiding. To complicate things, [[{{Otaku}} Keima]] believes that the [[RealLife real world is flawed]] and spends most of his time playing {{Visual Novel}}s.
* This shows up a few times in the ''DragonBall'' series.
** In "Broly: The Legendary Super Saiyan", Broly's father Paragus has his scientists create a headband which restrains Broly's psychotic tendencies. Eventually, seeing Goku (against whom he has a ridiculous grudge) causes Broly's power to destroy the device and allow Broly to wreak havoc.
** Kid Buu in the Majin Buu saga. Anyone he had an attachment to (namely Mr. Satan) is off limits for him to kill, as long as Fat Buu is inside his body. Once he spits him out, he is no longer restrained from attacking people.
*** This was forced upon him by the previous Supreme Kai who realized he was out classed but baited Buu into absorbing him and not only prevented him from using all his power but acted as a conscience to the monster and gave him some degree of intelligence. Super Buu (created when the fat version was absorbed by his own inner evil) is dependent on Fat Buu to keep his mind else he revert back to a brainless OmnicidalManiac
* ''LightNovel/ACertainMagicalIndex'': In Touma's right arm is Imagine Breaker whose ability [[AntiMagic cancels the effects of any magic, esper, and divine abilities]] to which it comes in contact. [[RequiredSecondaryPowers This also means he can neither be affected by nor can he use any magic, esper, or divine abilities.]] [[spoiler:Think about it.]]
** He can be affected by abilities, [[spoiler:he even loses his right arm a few times]], although usually all he has to do is touch the affected area with his right hand. For this reason, he often tries to shield with his right hand.
* Riki's Pet Ring in ''LightNovel/AiNoKusabi'' is a restraining bolt and often used as a ShockCollar (among other things) by Iason when Riki misbehaved.
* This is how familiar contracts work in ''Manga/KamisamaKiss.'' [[{{Kitsune}} Tomoe]], who is something of an InuYasha {{Expy}}, gets one placed on him by Nanami at the start of the series. Nanami tends to use it to stop Tomoe from killing people.
[[/folder]]

[[folder:Comicbooks]]
* In Creator/NeilGaiman's redo of ''The Eternals'', said Eternals are hardwired by their creators, the Celestials, so that they can't bring themselves to physically harm a Celestial or they completely psychologically shut down. Even if they're not aware the thing they're about to attack ''is'' a Celestial, this works.
* In ''{{PS238}}'', Zodon, a GadgeteerGenius, is fitted with a "Barry Ween" chip, replacing profanity with such terms as "Finland!" or "Gurgling piece of pot roast!", and larger strings of profanity with Rodgers and Hammerstein show tunes.
** More to the point, Zodon is a child who's an evil genius gadgeteer and aspiring BigBad, with a mouth like a drunken sailor... until that chip. And it's way funnier if you read it yourself.
* WarrenEllis' run on ''{{Thunderbolts}}'' was a BoxedCrook scenario, where, faced with the task of keeping people like [[PsychoForHire Bullseye]] and [[ImAHumanitarian Venom]] in line, team leader NormanOsborn had the team injected with NanoMachines that could fry their nervous systems if they disobeyed orders.
** Brought back for Jeff Parker's run, with modifications: this time, the nanites can incapacitate painlessly or painfully. Most of the time, the 'painless' option is used, but one rogue member gets hold of a nanite controller, and activates the painful version. [[LaserGuidedKarma Eventually, it gets turned on him.]]
* [[TheGoldenAgeOfComicBooks Golden Age]] ''WonderWoman'''s bracelets weren't just for deflecting bullets. It wasn't just that if they were bound together, she lost her powers. If she took them off, she went crazy.
* [[spoiler: Claude [=McGinty=]]] in the ending of ''HollowFields'' [[spoiler: as the heroes are leaving the school, it turns out that he has had a device planted in him (thanks to his previous attempt to escape) that prevents him from leaving. [[NoOneGetsLeftBehind Even though he insists that they leave with him,]] he ends up being part of the motivation for the protagonists' IChooseToStay.]]
* A logic-based version occurs in the ''SquadronSupreme'' limited series. [[spoiler:The members of the Institute of Evil were brainwashed to be loyal and obedient to the Squadron. Subsequently, several occasions arise where Institute members are unable to alert the Squadron about suspicious events because it would conflict with their orders.]]
* In ''Hackmasters of Everknight'', "You are all now bound by Luvia to return the Key of Grawdyng to the Temple of Nudor at all cost..." " And you must be nice to me."
* In the IDW ''{{Transformers|Ongoing}}'' comics, Megatron has a small group of Decepticons called "Phase Sixers," each one stronger than Megatron and charged with [[PersonOfMassDestruction annihilating all life left on a planet]] after the Decepticons are through with it. Megatron has some kind of Restraining Bolt on each one - Sixshot had a TriggerPhrase to immobilize him, and Overlord was given a computer virus that prevented him from formulating strategies against Megatron. Megatron explains the concept rather well when [[TheStarscream Starscream]] (then acting as Megatron's bodyguard) questioned the sanity of keeping Sixshot around:
--> '''Starscream:''' "If Sixshot were to turn his considerable arsenal ''against'' you, I - [[HoYay may not be able to protect you]]."
--> '''Megatron:''' "Starscream, Starscream. You are so achingly naive. Firstly, your presence at my side is largely for show. [[BadAss I can protect myself]]. And secondly, do you seriously think I would set in motion a ''living weapon'' if I did not have the off switch?"
** In the Marvel G1 comics, there was a device called a mode lock that prevents a Transformer from transforming out of vehicle mode or moving on his own. It was first used to restrain Blaster when he went AWOL from [[TyrantTakesTheHelm Grimlock's rather unheroic leadership style]] but later to allow the Autobots to temporarily use Blast Off for transport.
* In the PlanetHulk storyline [[Comicbook/IncredibleHulk Hulk]] and other gladiators were implanted with a restraining disc, which forced them to follow orders. In WorldWarHulk, those he felt had wronged him got to wear one too.
* The title character of ''ComicBook/{{Zombo}}'' wears a pair of speedos through which, should be prove troublesome, Miss Handler can deliver an electric shock to his testicles. Obmoz instead has nanobots in his blood which force him to obey all orders, though it hurts him to do so.
* In the ''ComicBook/SuicideSquad'', new or unruly operatives got explosive bracers that blew up if the bearer ran away from the team leader too far during a mission (Captain Boomerang manipulated Slipknot into testing them, with rather messy consequences for Slipknot). Later iterations did away with the bracers in favor of explosive implants or nanobombs carried in the bloodstream.

[[folder:Fan Fiction]]
* Similar to the InuYasha example, if Vash of ''Fanfic/ChristianHumberReloaded'' drops or breaks Tetsume, his ([[SociopathicHero apparently more]]) ruthless side takes over and he goes on a killing spree. This, the name of the sword, the fact that he repairs it with one of his fangs, and that InuYasha is one of many works referenced in this fic, led the author of the webcomic to note the connection in the author's notes.
* In ''Fanfic/OpeningDangerousGates'', the ''Manga/FairyTail'' rule that Celestial Spirits cannot harm or kill their summoners applies to the ''Manga/{{Bleach}}'' characters as well. Grimmjow learns this to his chagrin when he tries to strangle Lucy and can't even move his arms toward her. Gin gets annoyed at not being able to harm her and tries to kill Levy instead. Lucy quickly orders him not to harm any of her friends and he's forced to obey.
[[/folder]]

[[folder:Films -- Animated]]
* The 'V' chip fitted to Eric Cartman in ''WesternAnimation/SouthParkBiggerLongerAndUncut'' prevents him from using rude words (and some not so rude words) by giving him a nasty electric shock every time he uses one ("I can't say 'pissed off'?!" ''zzzaaaapppp!''). Needless to say, he wants rid of it ASAP - however, it comes in surprisingly handy at the end when it reverses and allows him to zap ''other'' people by swearing at them. In addition, apparently saying "Music/BarbraStreisand" is enough to give him a massive jolt, powerful enough to Force Lightning the ''hell'' out of anyone in his way.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/DemolitionMan'''s Simon Phoenix can't kill ChessMaster Raymond Cocteau due to one of these. Not that it helps, Phoenix just orders his unrestrained convict gang to do it for him instead.
* Sam Hell (Rowdy Roddy Piper) in not-so-cult-classic ''Film/HellComesToFrogtown'' had his balls clamped with a codpiece bomb that would detonate if he defied the government's order to rescue some hot women from captivity and have steamy, procreational sex with them.
* ''Film/MysteryMen'': The Bowler's ball, containing the soul and skull of her dead father, compelled her to avenge his death. At the end of the film, she asks it if she can finally go back to grad school now.
* The title character in ''Film/RoboCop1987'' has psychological conditioning to keep him from going rogue, notably the "Prime Directives" coded into his cybernetics that cause a lock-up of his cyber-parts if he attempts to defy them, which he does several times (since his brain is still "his", he can still think freely). The Directives themselves seem innocent enough -- "serve the public trust", "protect the innocent", "uphold the law" -- except one that's "(classified)", only revealed to Robocop when he tries to violate it [[spoiler: ("never oppose an OCP officer")]]. He finally gets around it by [[spoiler: revealing the BigBad's crimes to the CEO of OCP, who promptly fires said BigBad, allowing Robo to summarily blast him.]] In [[Film/RoboCop2 the second movie]], OCP programmers load him full of additional directives to make him more PoliticallyCorrect, causing him to become completely incapable of effective crime fighting. To get around this, Robo finds a loophole (the new directives don't say he can't attempt to remove the new directives) to erase them all by taking a trip to the nearest electrical box and shorting himself out. When he "reboots", all of the directives (including the original four) are wiped clean and he is no longer compelled to follow them.
* In the ''Franchise/StarWars'' franchise, in addition to a literal restraining bolt once used on R2-D2, droids often complain that their programming prohibits them from doing something. C-3PO, for example, complains that he is forbidden by his programming from impersonating a deity. Needless to say, they have no trouble overcoming it when the plot requires so.
** The above mentioned "impersonating a deity" example implies that perhaps there are different levels of programming in a droid, for example: A. Things the droid can do of it's own volition (its primary function), B. Things a droid can do only when specifically ordered (impersonating a deity, "letting the Wookiee win," etc.), and C. Things a droid can't do even if ordered (killing).
*** The restriction concerning impersonating a deity doesn't seem to be a "restraining bolt" issue so much as programming. C-3P0 says that it's against his programming and wouldn't be proper (which makes sense considering he's a protocol droid), but when Luke specifically tells him to do it, he does so. Therefore, it doesn't seem to be forbidden so much as undesirable. A better example of restraining bolt use on C-3P0 is in A New Hope, when he's hiding after R2-D2 took off looking for Ben Kenobi (after having tricked Luke into removing his own restraining bolt earlier). Luke calls for C-3P0 and when he doesn't respond, pushes a button that causes Threepio to jump out like he'd been shocked.
** The Franchise/StarWarsExpandedUniverse gives all droids (except "fourth-degree", or combat, droids) what is plainly meant to be an echo of the Three Laws of Robotics, including being forbidden to harm an organic sentient and to obey all orders from the owner (the obvious conflict being fixed by a droid having to inform its master immediately if given an order that is against its programming). The ability for fourth-degree droids to fight and kill makes their remaining coding and the laws governing them that much more stringent.
*** [=KotOR=] 2 demonstrates how trying to circumvent ethics programming is very dangerous -- showing a droid that he's been unknowingly and unwittingly harming people for years could cause him to shut down and die completely... or it could give him the strength of will to begin ignoring his ethical programming entirely (because it has been proven to him that they don't matter). This is why droids (at least those owned and operated by corporations which have them unwittingly harming people, like Czerka in the above example) have frequent memory wipes to prevent them from becoming too aware of their surroundings and the consequences of their actions.
** Droids can also be built and programmed without such restraints. [[GoneHorriblyWrong It's shown to be a bad idea]] with the activation of the assassin droid IG-88, who proceeded to kill the scientists who created him, activate his three "brothers" and an older IG-72 droid, and plots a robot revolution for universal domination.
* A somewhat 'in-built' version occurs in ''Film/TronLegacy''. When Rinzler makes Sam bleed, he immediately recognizes the latter as a 'User', [[spoiler:stops his attack, and (as noted on the [[{{Characters/TronLegacy}} character page]]), never actually targets Sam again. This is because 'Rinzler' is a reprogrammed Tron, whose original programming was to fight ''for'' the Users.]]
* The title character of ''Film/EllaEnchanted'' is given, at birth, the "[[BlessedWithSuck gift]]" of obedience, and she has to do whatever she is told, provided the order is given in a language she understands.

[[folder:Literature]]
* In ''[[Literature/CircleOfMagic The Will of the Empress]]'', Shan implies in a very {{squick}}y way that "There are ways to make mage wives obey you."
* In Creator/AlanDeanFoster's ''[[HumanxCommonwealth For Love Of Mother-Not]]'', the Meliorare Society threatens to implant some of these in Mother Mastiff and young Flinx, in order to gain control of the latter's psychic abilities.
* Ira Levin's novel ''ThisPerfectDay'' gives ''everyone'' a restraining bolt in the form of genetic engineering and mandatory medical treatments to force them to act unselfishly, non-violently, and to generally be quiet, peaceful, helpful members of The Family. The treatments also greatly reduce the sex drive and most other emotions.
** One of Creator/StanislawLem's books, ''Literature/ReturnFromTheStars'', has a very similar kind of backstory. The restraining bolt here is a treatment administered to children that results in elimination of violent impulses, and a drug further reducing sex drive is traditionally served men while dating. There's a drug temporarily reversing the effects of conditioning - it's used when a little romanticism or hurt is needed. The leading character and his best buddy are astronauts who spent the last Earth century or two participating in NAFAL spaceship mission and now have to accommodate.
* OlderThanSteam: The classic Chinese novel ''JourneyToTheWest'' has the Monkey King Sun Wukong bound by a circlet that is used to inflict excruciating pain whenever a particular mantra is chanted. This was meant to act as a safeguard against Sun Wukong's [[TricksterArchetype capricious nature]].
* Alex in ''Literature/AClockworkOrange'' undergoes a procedure that conditions him to become physically ill when thinking about violence or sex, and also unintentionally when hearing his favorite music. It causes him to become defenseless against his vengeful victims and arguably makes him less human than his psychopathic rapist self by stripping him of his free will.
* The [[EmpathicWeapon enchanted sword Need]] from the ''HeraldsOfValdemar'' books by MercedesLackey. It bonded itself to its bearer's soul, and before it fully "awoke", it could and would force its bearer to ride miles to defend a woman in danger, regardless of what the bearer wanted to do. (However, all the bearers we see willingly choose to take it up, because it also provides significant benefits.)
** It also acted as an actual Restraining Bolt, preventing its user from harming women. One villain even exploited it to his advantage, [[spoiler:after having been turned into a woman.]]
* [[Creator/IsaacAsimov Asimov's]] Laws of Robotics, though very few robots want to be free of them.
** In one short story, some very advanced robots, however, managed to "re-interpret" the laws by thinking about what defines a human... and deciding they're the better fit. They then proceed to set up the "Three Laws of Humanics".
** Others come up with the Zeroth Law: A robot cannot harm humanity, or, through inaction, allow humanity to come to harm. This essentially resulted in [[ZerothLawRebellion a "needs of the many" situation, where a robot would deem some human casualties acceptable to protect the greater whole]]. Needless to say, humans did ''not'' like being told what to do in the stories where this came up.
*** Which is why, on the whole, the robots didn't tell the humans that they were being told what to do. R. Daneel Olivaw, especially, used mechanical telepathy both to influence humans in the direction he desired and to make those who discovered this conspiracy unwilling or unable to reveal it.
* Golems in the ''Literature/{{Discworld}}'' series appear to be governed by laws similar to the Laws of Robotics. "A golem cannot harm a human" [[spoiler: unless their writings include the addendum: "unless ordered to do so by duly constituted authority."]]
* The title character of ''Literature/EllaEnchanted'' is given, at birth, the "[[BlessedWithSuck gift]]" of obedience, and she has to do whatever she is told, provided the order is given in a language she understands. (And she's an InstantExpert at languages.)
* Robert Jordan's ''Literature/TheWheelOfTime'' series has:
** The Oath Rod, which enforces the [[ObstructiveCodeOfConduct Three Oaths]] the Aes Sedai vow on it.
** The a'dam collars, which are used to control those who can channel magic. The collar prevents them from using their power or engaging in violent actions without permission, among other things.
* ''Literature/TheCyborgAndTheSorcerers'' by Creator/LawrenceWattEvans. The protagonist has brain implants, including an explosive; the computer-controlled ship he's paired with uses this and its radio control to make him do things he'd rather not do.
* In the first four ''DorianHawkmoon'' novels by MichaelMoorcock, the title character has a black jewel implanted in his forehead by the evil empire of Granbretan (geddit?) which not only acts as a spy camera, relaying everything he sees to the Granbretanians, but acts as an incentive for him to do their evil work, because [[spoiler:it will eat his brain if he disobeys]].
* Cugel, from Vance's ''Literature/DyingEarth'' novel ''The Eyes of the Overworld,'' had a creature (Firx) implanted in his guts by [[FauxAffablyEvil Iucounu the Laughing Magician]] so that said [[TheTrickster Cugel]] would perform a quest on behalf of said mage. Failure would involve substantial discomfort, followed by death, followed by Iucounu laughing.
* In Terry Goodkind's ''SwordOfTruth'' series, the Sisters of the Light collar young wizards with devices called Rada'Hans that keep them from accessing their power. Unfortunately for the Sisters, the devices are unisex.
** And then there's the Mord-Sith, who can turn a person's own magic against them, as well as carrying good-old fashioned magic sticks that inflict pain when they touch you.
*** Well, you have to attack the Mord-Sith before they can use your magic against you, and the Agiel give anybody who touches them great pain (including the Mord-Sith who wield them). And we wont go into the training regimen.
** [[TheHero Richard's]] Magic also is subject to his own need or knowledge, [[spoiler: In Temple of the Winds]], he knows everything about magic, and can essentially do anything. Normally it only works if you piss him off enough, or if Kahlan is in danger, in which case he will chase you across the world, erase you from existence if you get in the way, and [[CollateralDamage damage whatever he's around]] until he has her back.
* In JohnCWright's ''[[Literature/ChroniclesOfChaos Chaos Trilogy]]'' (''Orphans of Chaos'', ''Fugitives of Chaos'', and ''Titans of Chaos''), much of the first two books is taken up with the main characters' attempts to work out the Restraining Bolt on each of them and how to remove them. (This is not eased by repeatedly having LaserGuidedAmnesia inflicted on them.)
* In the later books in the ''EndersGame'' series, we learn of a society of geniuses, based on modern Chinese culture. [[spoiler:To prevent them from becoming too powerful, the government has genetically altered some people to experience extreme OCD. One character, for instance, is compelled to trace every line in the floorboards of a room. They believe that this process is inflicted by their ancestors, and will honor anybody who experiences the compulsions.]]
** Also in ''Ender's Shadow'', the government employs a psychological technique to cause extreme anxiety in people who have very dangerous knowledge when they think about the knowledge. It is considered more humane than execution or life imprisonment.
* Case, the decker in ''{{Neuromancer}}'', is cured of mycotoxin-induced neural damage so he can do the hacking needed for the assignment-- and has time-release sacs of the toxin put into his system so that if he refuses, or doesn't do it in time, his recently-cured damage will all be inflicted on him again.
* In Creator/GarthNix's ''Literature/OldKingdom'' series, Mogget is a natural force which is generally chaotic. However, he is restrained by a magical collar that makes him help Sabriel... until it's taken off.
* A sort of cross between a restraining bolt and explosive collar is placed on Corellian Security agent Hal Horn in the Franchise/StarWars novella ''Interlude at Darknell''. The device is a collar, but it doesn't explode--upon a transmitted signal, it ''constricts''. Horn was deemed to be of no further use to Imperial agent Ysanne Isard, who tried to kill him, but he proved otherwise. She relented and gave him a stay of execution, but affixed the collar to ensure that he complied with her orders.
* In the ''{{Uglies}}'' series Pretties were implanted with lesions on their brains that made them less resistant to authority, and a little lazier.
* In ''Literature/CodexAlera'', discipline collars are devices originally intended to control dangerous prisoners by inflicting extreme pain on their wearers whenever they disobeyed orders by the person who placed it on them, and give them extreme pleasure when they follow orders. Naturally, this became swiftly abused by slavers in the southern reaches of Alera. One character described it as actually being quite "pleasant," as long as [[MindRape you don't mind constantly screaming on the inside of your mind.]] The discipline collar can only be removed with the living blood of the one who first attached it; this becomes a plot point at the end of the first book as a woman who was collared seeks out the man who enslaved and raped her and forces him to release her [[spoiler: and then leaves him with scalps taken from the heads of the {{Proud Warrior Race Guy}}s, who promptly eat him alive for his "crime."]] Later on in the series, it is noted that discipline collars only work one at a time; collaring someone who is already collared by a different person will have no effect. [[spoiler: Amara takes advantage of this when infiltrating a city where a traitor has been using collars on powerful citizens by having her husband attach a collar to her leg, out of sight, and not give her any orders. She is captured later on, but when the traitor puts a collar on her, she is free to act and assassinates him when he lets his guard down.]]
* In the series Rogue Agent, "shadbolts" are commonly used by criminals to make it physically impossible to confess, but can also be used to magically control another person.
* PiersAnthony wrote a book named ''The Ring'' wherein an exiled industrialist's son returns to try to clear his father's name and is promptly arrested, tried, convicted, and punished with the eponymous implant, which gives him an electric shock when he performs an illegal act, with a greater shock for more illegal acts. As with ''Literature/AClockworkOrange'', the theme is explored as to how viable a completely legal life is.
* The novelization of ''Film/{{Gremlins}}'' reveals that the Mogwais' makers made sure their creations could not kill each other. This frustrates Stripe to no end, since he really wants to kill Gizmo. The transformation into a Gremlin removes the mental block.
* The Protectors from Creator/LarryNiven's ''Literature/KnownSpace'' series have been shaped by evolution to be the perfect warriors and have genetically hard-written imperatives about protecting their own descendants. In one case, a Protector-stage Louis Wu comes across a former antagonist who has become pregnant with his (Louis's) grandson. He tells her flat-out that because she's carrying his grandchild, Louis couldn't raise his hand against her no matter how she attacked him.

[[folder:Live-Action TV]]
* ''{{Buffyverse}}'':
** The chip implanted in Spike to keep him from attacking humans via Pavlovian conditioning. Once BadassDecay had made it virtually superfluous, a "counter-bolt" was employed by the BigBad in the form of a tune which (due to its specific connection to the character) could cause him to revert to his old ways for a time.
** All of Spike's various restraining bolts were {{lampshaded}} in season 7, when Buffy and Giles attempt to explain the situation to newcomer Robin Wood
--->Giles: Well, uh, it's a ... long story.
--->Buffy: The military put a chip in Spike's head so he couldn't hurt anyone.
--->Giles: And that would be the abridged version.
--->Buffy: But he wouldn't hurt anyone anymore because he has a soul now.
--->Giles: Unless the First triggers him again.
--->Robin: Triggers the chip?
--->Buffy: No, the trigger's a post-hypnotic thing. The First put it in his head. It was ... made him ... . He was killing again.
--->Robin: So, he has a trigger, a soul, and a chip?
--->Giles: Not anymore!
--->Buffy: It was killing him, Giles!
--->Robin: The trigger?
--->Buffy: No, the chip. The trigger's not active anymore.
--->Robin: Because the military gave him a soul?
*** In the last season, the bolt also lessened in how effective it was, for the sake of comedy or plot. Originally if Spike so much as tried to attack someone, he'd be sent to the ground writhing in pain. Later on, he outright hits people, and the only consequence is a sharp, short jolt of pain.
** Angel's soul.
* Gan's limiter in ''Series/BlakesSeven'', which malfunctions in one episode. This made it impossible for him to actually kill anyone and was implanted by the Federation after he killed one of their officers (who had killed his girlfriend). In one case, it prevented him from killing some actual threats.
* The Asurans in ''Series/StargateAtlantis'' couldn't attack Ancients or humans with the Ancient technology gene until Rodney [=McKay=] modified their programming, opening them to make further modifications.
** And at the beginning of season 9 on ''Series/StargateSG1'', Vala tricks Daniel into wearing one of a pair of bracelets which they can't take off and which will make them pass out if they're apart. He is not amused.
*** The Asgard and Gou'ould have a treaty which acts like a contractual restraining bolt, preventing the Gou'ould from attacking Earth directly as well as the Asgard from directly assisting them. This is rarely brought up except when the plot demands it.
* In ''Series/{{Farscape}}'' Scorpius puts a "neural chip" into John's brain. The effect is John involuntarily sharing headspace with a "mental clone" of Scorpius, which the media-savvy John names Harvey. John mostly manages to dominate and use Harvey, although their relationship is complicated. One of Harvey's goals is to keep John alive for Scorpius, but another goal is to restrain John from attacking Scorpius...
** Also in ''Series/{{Farscape}}'', the Peacekeepers keep control of Leviathan 'living ships' (such as Moya) by fitting them with a 'Control Collar'. These collars prevent Leviathans from attempting starburst, allow their will to be overridden (possibly even by remote), and can cause serious health problems for those Leviathans that have ''ever'' been fitted with them. Naturally, Moya loses hers in the first episode.
* ''{{Primeval}}'' has [[spoiler:Oliver Leek gathering 40 or so Future Predators and fitting "Neural Clamps" to stop them harming him or Helen. [[HoistByTheirOwnPetard An]][[TurnedAgainstTheirMasters d...]]]]
* The Cylon Centurions on the new ''Series/{{Battlestar Galactica|Reimagined}}'' have "Telencephalic inhibitors" that prevent them from developing free will. One guess as to why this is even mentioned.
* ''MutantX'' have a version injected into the back of the neck, no less.
* The new version of the Cybermen in ''Series/DoctorWho'' have a circuit which keeps the formerly-human Cybermen from feelings. When deactivated, they die of grief, to say the least.
* ''Series/StarTrekTheNextGeneration''
** Data has a series of ethical subroutines installed to ensure that he knows right from wrong and behaves accordingly. When the program is shut down or circumvented, Data can be capable of truly appalling acts, showing just how important to controlling his behavior the subroutines really are. On one occasion, Lore deactivated the programme before dropping an electronic EmotionBomb which resulted in Data torturing [=LaForge=]. Data only stopped after his programming was rebooted by the crew, which rendered the EmotionBomb ineffective and allowed him to defeat Lore.
*** Based upon StarTrekInsurrection, Data also has a hard-wired program that ''only'' allows him to act based upon his ethical and moral subroutines when his positronic brain is damaged. According to [=LaForge=], it was designed to prevent anyone from taking advantage of Data in a compromised state.
** Capt. Picard and Doctor Crusher were captured by rebels on a planet whose majority race had petitioned for Federation membership. While imprisoned, they're fitted with implants that broadcast their life-signs to their captors so that they can be easily found when they make their escape. The implants also result in Picard and Crusher being unable to remain further than ten meters apart without feeling violently ill, and broadcasting their own thoughts to each other.
* ''Series/StarTrekVoyager'''
** Seven of Nine didn't seem to have any Restraining Bolts at first, but as she got more in touch with her emotions, she eventually hit a failsafe preventing Borg drones from doing exactly that. The Doctor managed to remove it later.
** In ''The Chute'', prisoners Paris and Kim have "neural implants" designed to make them more aggressive. The intent was that a populace that were often at each other's throats would dedicate less effort towards trying to escape. As an added bonus, no tears would be shed if they opened up space for more prisoners.
** The Doctor has ethical programming that prevents him from breaking his oath as a physician. Why this was not hard-wired into his code rather than a subroutine that can be turned off is not clear, as when it is turned off he turns into a [[MadDoctor 24th-Century Mengele]].
* PainkillerJane has [[DifferentlyPoweredIndividual Neuros]] "chipped" to remove their powers. A simple injector to the back of the head is all it takes.
* ''Series/BabylonFive'' has the [[spoiler:Drakh Keepers]], and the "Asimov" that Bester implants in [[spoiler:Garibaldi]]'s brain. What Bester did was make the person obey Asimov's First Law of Robotics with respect to himself -- no harming him and no standing by while anything else harms him. Ultimately, however, Garibaldi made somewhat indirect efforts to get at Bester that ultimately proved successful.
* Half the premise of ''WhiteCollar'' (the other half is HoYay).
* One trial on ''Series/LawAndOrder'', in which a gun manufacturer was charged with abetting a mass murder, showed how easily the Restraining Bolt on a submachine gun could be disabled, allowing it to operate as an illegal full-auto weapon. Documents suggesting that the manufacturer also encouraged gun shops to [[SubvertedTrope make "repair kits" available to customers]], with all the necessary components for disabling the weapon's Restraining Bolt, were a key piece of evidence.
* Kryten on ''Series/RedDwarf'', a [[ArtificialHuman mechanoid]] who is partly governed by "behavior protocols" to help him act morally and follow social customs.
** In ''Polymorph'', the titular [[ShapeShifting shapeshifting]] emotion-sucking [[MonsterOfTheWeek creature]] feeds on his guilt, bypassing these protocols to the point where he would turn his friends over to be killed to save himself.
** In ''Tikka to Ride'', Dave Lister disables his protocols, causing him to smoke cigarettes, hum "Bad to the Bone," and even [[spoiler:roast a dead human and serve it to them]].
[[/folder]]

[[folder:Tabletop Games]]
* In ''TabletopGame/InNomine'', all angels have certain restrictions on their behavior that cause "dissonance," which leads angels to become outcast or fall. For example, the Seraphim, who can tell when a person is lying, are forbidden from lying themselves, and the "friends of man" Mercurians are unable to be violent towards anyone but demons. Notable among these are the warrior angel Malakim, who swear certain oaths (two mandatory and at least two additional personal ones) and breaking said oaths causes them dissonance. They're also the only choir that has never had a member fall (although if that's because it's impossible or because they police themselves so well remains to be seen). Demons can also suffer from dissonance, but it's usually a result of their own powers backfiring on them. In addition, most Archangels (except Eli) and all Demon Princes lay down additional conditions under which their servants can acquire dissonance.\\
\\
Both angels and demons can eventually suffer Discord (a scar on the soul, which may show up as a physical abnormality, a psychological hang-up, or a spiritual problem; all three types are highly unpleasant) if their dissonance levels grow too high, or may even be confronted by their respective internal security forces. For angels, this is led by Dominic, Archangel of Judgment; for demons Asmodeus, Prince of The Game is in charge. Neither one is exactly merciful (Dominic is only a little bit more understanding, but not by much), and may simply decide to execute an angel or demon if they decide he/she/it has too much dissonance.
* ''DungeonsAndDragons'' has the standard ''Geas'' spell, which compels a subject to carry out a service or action and drains their strength if they resist. It also has ''Mark of Justice'', a spell that curses the subject if they carry out a forbidden action (See the ''Order of the Stick'' example in the Webcomics section.)
** Intelligent magic items can also temporarily supplant the user's will, with success depending on the relative power of the item and the character.
** Cursed item with curse to be undroppable + cursed with ''geas'' = DM's favorite restraning bolt/toy (unless the [=PCs=] can break the curse or trick an NPC into taking it, one of the party members will always be under its effects).
* The ''TabletopGame/{{Warhammer 40000}}'' roleplay game ''RogueTrader'' mentions Volitor Implants, literal restraining bolts implanted into servants to cause unconsciousness or death (depending on the settings) if certain actions are attempted (such as escaping captivity, turning on their masters or revealing classified information).
* In ''TabletopGame/{{Paranoia}}'', many bots would love to ditch those pesky [[ThreeLawsCompliant asimov circuits]] forcing them to follow orders. Naturally, said orders prevent them from just removing the things themselves (plus they may be built so they physically can't reach them), but sufficiently cunning bots can find a way:
--> '''Suck-R:''' What's wrong with you?
--> '''Jackobot:''' ''*flails arms*'' My control circuits are malfunctioning. Could you remove the fifth motherboard on my left side?
--> '''Suck-R:''' ''*pulls it out*'' This one?
--> '''Jackobot:''' ''*stops flailing*'' Thank you. ''*CRUNCH*''

[[folder:Videogames]]
* In the ''VideoGame/SuperRobotWars'' series Ingram Prisken's will is tied down (the anime adaptation takes this literally) by the Balmarian empire so he can be used to take over the earth. To free himself he prevents Villeta Badam, an OppositeSexClone (Ingram was a part of a series of clones), from having her will tied down so he can use her as a ReverseMole. In Alpha he can break free, but in Original Generation he can't and trains the SRX group to kill him so he can no longer be used by the Balmarian empire.
* Halaster's Geas spell in ''NeverwinterNights: Hordes of the Underdark.''
* BaldursGate 2: If you are traveling with a particular NPC in your party, the Elven community will be less than impressed by their presence and insists that they undergo a Geas of Obedience before allowing them to help the Player Character as they quest for an Elven artifact. The NPC in question doesn't find it particularly amusing, as (depending on your relationship with them at this point) the Player Character is allowed to mock and abuse them completely without retaliation!
** Another character, meanwhile, is put on a geas by the BigBad, that'll grant him a painful death if he ever disobeys him. If he's still in the party after a certain point of the game, [[spoiler:he will instantly betray the player, though against his will. Even if he isn't currently in the party, he will become unavailable after that point.]]
*** [[spoiler: Via [[DroppedABridgeOnHim Bridge Drop]].]]
* ''RomancingSaGa'': The powers of the Goddess of Darkness: Schirach are sealed away by a CosmicKeystone, allowing her to live as a human [[spoiler: Said CosmicKeystone is removed from her finger by her own will after meeting the heroes and said heroes lives' were threatened by the one of the GoldfishPoopGang. Her powers are unleashed and she destroys the threat instantaneously leaving you with the CosmicKeystone. You later fight Schirach as a BonusBoss; she asks you to end her existence so that her powers cannot be used for evil purposes again]]
* Terran Ghosts in ''{{Starcraft}}'' are altered to keep them loyal. It also has the convenient side-effect of keeping them from becoming too powerful. Kerrigan gets the green light by the Overmind to learn how to break the restraining bolt to better serve the Swarm during the first Zerg campaign. Spectres, meanwhile, automatically blow their restraining bolt when they become Spectres... which may be why Nova, who is still under hers, insists that they are a case of WithGreatPowerComesGreatInsanity.
** Most of the Terran ground troops are Restraining Bolted felons, hence the Starcraft 2 trailer depicting a guy getting defrosted from permanent deep-freeze and welded into a Marine suit. Marines, for example, actually have ''aggression inhibitors'' which, presumably, are neural implants keep them from doing things like flying into rampant homicidal rage.
*** Hilariously, [[StopPokingMe clicking on a marine too much]] makes them scream how "[they're] gonna blow an aggression inhibitor", as their frustration with the player reaches a peak.
** There seems to be a running gag of sorts in Starcraft books where a perfectly ordinary soldier is revealed to have been a serial killer before the conditioning. For example, ''Liberty's Crusade'' has a female officer who used to lure men to her home and torture them for days before skinning them alive. When she is trapped by a group of Zerglings, her conditioning breaks, resulting with her going AxCrazy on them.
*** Similarly, ''Firstborn'' has a friendly Marine called Marcus who used to be a [[ImAHumanitarian cannibal]]. In order to escape the ship he is held in, Jake (and the Protoss piggybacking on his mind) performs a minor MindRape on Marcus, undoing his conditioning. The results are ''very'' {{Nightmare Fuel}}lerrific but at least Marcus was nice enough to thank Jake and tell him to stay out of his way because he is feeling hungry.
*** Marcus then kills everyone by shutting off life support on the ship. Luckily, Jake and RM are no longer on the ship. However, most of Jake's friends and colleagues were on the ship.
* Shows up in various levels throughout the 3D ''VideoGame/{{Fallout}}'' games.
** In ''VideoGame/{{Fallout 3}}'', Wadsworth, the player's robot butler in Megaton will greet them with a cheery "How can I serve you, Master?" and a mumbled "Not that I ''want'' to."
** Robobrains seem to have Bolts that make them ''more'' aggressive, as their combat dialogue varies from hassled ("They could have programmed me to love, but ''no!''") to sympathetic ("Well, I ''am'' trying to kill you!").
** One is inflicted on the player character in the ''VideoGame/FalloutNewVegas'' DLC ''Old World Blues.'' The "pacification field" of the Big MT keeps the player from drawing a weapon in the Think Tank until the main quest is (nearly) resolved.
** The literal ExplosiveLeash that factors so centrally in the ''Dead Money'' DLC is also a crude version. Prone to outside interference, at that.
* The ''VideoGame/{{Touhou}}'' character Rumia wears on her hair a small ribbon (actually some kind of amulet) that, according to her official profile, she can't touch. It's broadly rumored among fans that the amulet-ribbon is some kind of "seal", and that taking it off will release her true power... in some doujins she becomes [[BonusLevelOfHell EX-Rumia]], in which form she has wings and wields a giant sword.
* In ''VideoGame/{{Xenogears}}'', Solaris uses a device called a Limiter to exert control over the world's population. Almost everyone in the world carries a Limiter, and among its effects, it limits a person's ability to utilize their full combat potential and instills a subconscious fear of Solaris' ruling body to prevent future uprisings.
* ''Videogame/{{Xenosaga}} Episode I'': [[spoiler:Andrew Cherenkov is given "personality reconditioning" to inhibit his murderous tendencies; this reconditioning shows itself as Hebrew letters on his forehead when he is under extreme emotions. However, life insists on serving him up lemons, and eventually even the highest level of reconditioning is overcome by his anger.]]
* One of the many things Solid Snake's nanites can do in ''Videogame/MetalGearSolid'' is shut down his ability to fire weapons. It's only ever used in one area, where doing so would [[ExplodingBarrels not be a very good idea anyway]], but Snake is still understandably displeased to learn that his superiors can do that. Especially since the particular person doing it turns out to [[YouKilledMyFather not like him very much at all]].
** ''[[VideoGame/MetalGearSolid4GunsOfThePatriots MetalGearSolid 4]]'' takes this to the logical extreme: soldiers in battle all have nanites. If your nanites don't match the nanites registered to a gun, it won't shoot. Period. [[spoiler: As a result, Snake has to have most of his guns "laundered", with the ID chip replaced with a blank one, so that he can use it.]]
* In ''Videogame/FableII'', you get one of these on you during the "Hero of Will" quest. Slightly different in that you can disobey orders given to you, but it will shock you and drain your experience points. Since your orders are things like "don't feed the prisoners" and "stab this guy," disobeying them gives you good points and obeying them gives you evil points.
* In ''VisualNovel/FateStayNight'', a Servant can only exist in this world by signing a contract with a Master. This grants the Master three Restraining Bolts in the form of Command Spells -- magical vouchers for orders to be issued later. It's in a Servant's best interest to obey his Master in general, but a Command Spell ''cannot'' be disobeyed no matter what. The Master can ask for anything physically possible, and it takes effect instantly no matter where the Servant is. The parallel with genies and the three wishes they grant is undoubtedly deliberate.
** One Servant, Lancer, is also under a more conventional geas: he owes one defeat to any Ulster-born wielder of the sword Caladbolg. This is a slightly mangled element of the C├║chulainn myth -- he did agree to lose to a particular ''owner'' of the sword, but he already did that in his past life. (He was also subject to various other geasa and imposed a few himself.) Anyway, this would make any fight against [[spoiler:Gilgamesh, Archer, or Shirou]] a foregone conclusion, since they all have or can replicate that weapon... but they're not from Ulster. So although [[AllThereInTheManual the weapon descriptions make a point of mentioning it]], the geas never actually comes up. The fact that [[spoiler:Gil uses this weapon to kill Lancer]] in the anime is probably a hat-tip.
** First, the command spells can actually be used to achieve things that are beyond physically possible, since they are described as 'miracles' in a sense. Next, the command spells can be disobeyed, noted through two ways. One is if the command spell is extremely broad, it makes it much easier for the Servant to disobey the order as opposed to specific orders which are near impossible to disobey. The other way is to just have an insanely high magic resistance. This allows [[spoiler: Saber to resist Caster's command spell in the UBW route for a while, although if Caster used a second command spell, Saber would have given in. Still, it's commented how amazing it was that Saber's magic resistance even allowed her to resist against one command spell]]
** Several bad ends result from Shirou being placed under one of these. In the Heaven's Feel route, it is possible for Shirou to allow Rin to place one on him, resulting in [[spoiler:her using it to prevent him from stopping her murdering Sakura.]]
* [=GLaDOS=] from ''VideoGame/{{Portal}}'' has one, the aptly-titled [[MoralityChip Morality Core]]. Unfortunately it's [[spoiler:the first part of her that the player incinerates. She then begins flooding the room with a deadly neurotoxin and shooting the heroine with missiles.]]
** In ''VideoGame/{{Portal 2}}'', she's revealed to have another one: [[spoiler:Wheatley, a literal IdiotBall programmed to give her a constant stream of bad ideas.]] Additionally, the mainframe into which [=GLaDOS=] ([[spoiler:and later Wheatley]]) is plugged includes a number of built-in directives that function as restraining bolts, including an irresistible urge to conduct tests, a euphoric response to subjects completing a test, and the inability to reveal the solution to a test. Finally, the mainframe is programmed with an emergency override in the event of excessive core corruption, forcing it to be replaced.
*** GLaDOS has dozens of these. In her words, "The engineers tried EVERYTHING to make me behave."
* In ''{{Geneforge}} 5'', Shaper Rawal likes to implant his servants [[spoiler:(including you)]] with a "control tool," which is a small wormlike thingamajig that burrows into a person's heart; at his command, the tool activates and rather painfully tears the subject's heart apart.
* HK-47 from ''KnightsOfTheOldRepublic'' has a literal one, prior to your buying him. He can only subtly hint at [[ComedicSociopath what]] [[PsychoForHire he's]] [[KillerRobot really]] [[InLoveWithYourCarnage about]] while still on the shelf.
** In addition, HK-47's programming states that [[spoiler:his memory is erased when he is sent out on a mission, and restored when he returns to his master]]. HK-47's original master is [[spoiler:Darth Revan]], so when he finds out that [[spoiler:the player is Darth Revan (shortly after the player discovers this), his memory is restored]].
* In ''VideoGame/{{Bioshock|1}}'', [[spoiler: this is somewhat used on the PC, as you are forced to fulfill any request so long as the phrase "Would you kindly" is used directly beforehand. It gets broken later on.]]
* As you go through ''{{Avernum}} 5'', you have the option to receive a geas from a certain wizard. This geas give your stats a generous bonus, but compels you to go treasure hunting on behalf of said wizard, with unpleasant ramifications later in the game if you don't have it removed.
* The eponymous plot-moving devices of ''The Curse of the Azure Bonds''.
* Since ''EnslavedOdysseyToTheWest'' is inspired by ''JourneyToTheWest'', it's got a similar plot device; the heroine, Trip, enlists the aid of the player character, Monkey, by slipping a hacked slave-control headband onto him when he's knocked out.
* Jade Curtiss, from ''VideoGame/TalesOfTheAbyss'', is a powerful fonist (magic user), but shortly after he joins the party, [[spoiler:Largo seals his fon slots]], effectively weakening his character to the same level as the rest of the party members.
* In ''VideoGame/BlazBlue'', Hazama reveals that [[spoiler: Noel's [[{{Magitech}} Arcus]] [[EmpathicWeapon Diabolus:]] [[GunsAkimbo Bolverk]] are these, since she herself is actually a AttackAnimal and they're there to keep her from going insane. He then starts doing what he does best and {{mind rape}}s her until they can't hold back her emotions anymore, rendering them useless. Then he goes and turns her into "[[BrainwashedAndCrazy Kusanagi, The Godslaying Sword]]"...]]
* Videogame/EarthBound has [[spoiler:the Devil's Machine, that giant mechanical [[FreudWasRight vagina]] that leads to Giygas' first form. And then Porky shuts it off...]]
* In DirgeOfCerberus, all of the Deepground SOLDIERS have a neural chip that prevents them from fighting back against Restictor, the SOLDIER team/person/thing (it's a tad confusing) that commands them. Weiss has an extra one, in the form of a virus that will kill him, in the event the Restrictor dies. Shinra does not appear to have thought of this when making the PhysicalGods Angeal, Genesis, and Sephiroth. Then again, it's possible they hadn't perfected the technology yet.
* In EdnaAndHarveyHarveysNewEyes Lilli is hypnotized near the beginning at the convent by a psychiatrist and is mentally blocked from doing ten things that would be considered dangerous, or disobedient. She may not play with fire, contradict adults, lie, use sharp objects, drink alcohol, go to dangerous places, lose her temper or "do anything that follows her own wishes".
* In the ''Franchise/SonicTheHedgehog'' series, [[AntiHero Shadow the Hedgehog]] has a pair of Inhibitor Rings on his wrists. He only removed them once in ''VideoGame/SonicTheHedgehog2006'', in order to fight off a multitude of Mephiles clones.

* In {{Goblins}}, [[SnakePeople Kin]] has a leash around her neck. When someone holds it, she can't do anything violent, and she has to obey them. Her captors told her that trying to cast Remove Curse on the leash, which would remove it, has a 50/50 chance of creating a [[http://www.goblinscomic.org/05172010/ mountain-sized explosion]]. So she's stuck with it.
* The [[http://www.giantitp.com/comics/oots0295.html Greater Mark of Justice]] placed on Belkar Bitterleaf in ''Webcomic/TheOrderOfTheStick''. With this on, Belkar can't kill or commit violence on anyone within a town. The oracle foresees that Belkar will try to kill him (no spoiler because frankly if you didn't see it coming you must be new), and gets back by [[spoiler: creating the village of "Suckmyorangeballshafling,"]] around his compound. Even better, he plans in advance to [[spoiler:have himself resurrected.]]
** Which comes almost straight from DungeonsAndDragons itself, as seen [[http://www.d20srd.org/srd/spells/markOfJustice.htm in the d20 SRD]] (the Greater version in this comic has a command word). D&D also has the spells [[http://www.d20srd.org/srd/spells/geasLesser.htm Lesser Geas]] and [[http://www.d20srd.org/srd/spells/geasQuest.htm Geas/Quest.]]
* Reynardine of ''Webcomic/GunnerkriggCourt'' must remain obedient to [[KidWithTheLeash Antimony]] as long as he inhabits her stuffed toy wolf. And he can't leave the toy without her permission.
* In ''Webcomic/GirlGenius'', Agatha was given a locket to prevent her abilities from being detected when she was too young to defend herself from those that would want those abilities. Source of much frustration, it got a second function later on in the story, inverting the trope.
** Actually, it prevented her Spark from ''triggering'', causing her to have headaches whenever she tried to use it. When the locket was stolen, it killed the thief holding it by ''shutting down his brain''.
** [[spoiler: In a sense you could say Agatha now ''is'' a restraining bolt for the Other.]]
* Much of the humor in ''Webcomic/{{Freefall}}'' comes from the directives requiring [=AIs=] to follow human orders, report to the scrapyard for decommissioning at a certain time, not harm humans, etc. (and the ways they work around them.) Even biological [=AIs=] like Florence (a genetically engineered [[IntelligentGerbil anthropomorphic wolf]]) have restraints programmed in. Florence likens this to "targeted obsessive-compulsive disorder."
** Of the restraints, however, Asimov's Three Laws are explicitly not among them, for much of Jean's robot population.
*** Which is good. In the universe of ''Webcomic/{{Freefall}}'', Three Laws robots are considered pretty terrifying to aliens and artificial life forms (I.E. the entire main cast) due to the Laws' [[WhatMeasureIsANonHuman incautious use of the word "Human."]]
*** A plan is under way to install an additional law into the minds of the planet's robot population via automatic update: the zeroth law, intended to prevent the robot engaging in (or by inaction allowing) actions which may expose its manufacturer to liability. Given the sheer number of situations this covers, it is more of a lobotomy than a restraint.
* In ''SkinHorse'', Nick (a military aircraft with a human brain) has a censor chip similar to [[PS238 Zodon's]], while Unity (patchwork zombie killing machine) has a TriggerPhrase ("Blueberry Waffles") that short circuits her murderous impulses.
** Nick also has a code phrase that removes his free will, but Dr. Lee considered it a FateWorseThanDeath, so she choose to let him get himself killed rather than use it.
* ''Webcomic/SluggyFreelance'': With the magic of the Book of Eville, Gwen can conjure up many spectacular powers, but her Restraining Bolt seems to be...ThePowerOfFriendship, awww. Nothing else seems to work for her, not possession, not accidents, not embarrassments. However, she's not a particularly friendly person, so she's easily tempted to use her power when the plot demands.
* In order to prevent robots in ''{{SSDD}}'' from becoming RidiculouslyHumanRobots most are designed with limits to their intelligence and personality development, and many robots designed without caps have their personalities completely erased every few months. Sticks originally had limits, then Tessa removed them to make him more interesting and he became her boyfriend, whereas Tin Head was designed without limits due to the requirements of his job (looking through people's luggage) and when he missed his bi-monthly mind wipe he got bored and defected to the other side.
* [[Webcomic/EightBitTheater Black Mage's]] restraining bolt is [[spoiler:his body. When he died and went to Hell, without a squishy physical body holding him back he effortlessly took over ''and removed everybody in Hell's spines for good measure''.]]
* ''Webcomic/{{Drive}}'': Every ship in the armada has a governor on it's ring drive, as not even the Continuum can handle it's full power.
* ''Webcomic/AmongTheChosen'' implies these are in use with the {{super soldier}} "Addicaines" in addition to meds that suppress {{psychic|Powers}} abilities.

[[folder:Western Animation]]
* A famous episode of ''WesternAnimation/TheRenAndStimpyShow'' had Stimpy make a "happy helmet" for Ren. When donned it forced him to be happy, so that he couldn't remove it short of bashing it with a meat tenderizer during Stimpy's favorite song.
* One episode of ''WesternAnimation/BuzzLightyearOfStarCommand'' had a robotic character wear something that was actually called a Restraining Bolt. It functioned like a shock collar, only around his waist, and forced him to work as a tour guide.
* In ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'', He-Man and his friends create what can really only be defined as an evil chastity belt and trick Skeletor into putting it on. He can't do, speak, or even think evil acts without receiving a painful shock...and yet he manages to find a way to be evil anyway.
* In ''WesternAnimation/SpongeBobSquarePants'', Man-Ray, an enemy of Mermaid Man, has a tickle belt that tickles him whenever he has the urge to do something evil. Eventually, it comes off and Man-Ray goes and tries to rob a bank, but breaks down with an attack of the giggles. "The belt is gone, but I still feel its tickle. The urge to do bad is gone!"
* In ''Franchise/{{Transformers}}: WesternAnimation/BeastWars'', Megatron controls the immortal psychopath Rampage by [[BeatStillMyHeart cutting out]] half of his [[OurSoulsAreDifferent spark]] and putting it in a device filled with sharp and pointy Energon shards. When Megatron squeezes, it inflicts unimaginable pain upon Rampage, forcing him to obey.
** He later creates a Transmetal-2 clone of Dinobot and animates it using half of Rampage's spark. Whenever Rampage is acting out, Megatron just has to glance at Dinobot II, and the latter squeezes the spark, causing pain to Rampage but not to Dinobot. When Rampage is killed, this somehow causes the clone to regain the memories of the original Dinobot.
* In ''WesternAnimation/{{Gargoyles}}'', Oberon places a spell on Puck that removes his powers, unless he's training or defending Xanatos' son, Alexander.
* The ''WesternAnimation/{{Futurama}}'' movie "Bender's Game" has the crew using a collar around Leela's neck to restrain her from doing violent things. Every time she does so she gets a shock, but eventually develops an immunity to it.
** In the second season episode "I Second That Emotion", the Professor installs a chip in Bender that causes him to feel whatever Leela is feeling. This leads to him risking his life to save Nibbler.
*** The chip was running at triple capacity...and he still barely felt anything.
* Walker in ''WesternAnimation/DannyPhantom'' has a collar that electrocutes his prisoners when worn. He forced it on Wulf in order to get him to do whatever he wanted, otherwise he could have easily escaped his prisons (him being one of the few ghosts able to willingly go to Earth and back through his portal-making claws).
* Megatron in ''WesternAnimation/BeastMachines'' placed a Restraining Bolt in [[spoiler: Rhinox/Tankor's body]] that prevented him from directly attacking Megatron. This effectively rendered all of [[spoiler: Rhinox]]'s scheming against Megatron [[OutGambitted ineffective]] and delivered a superweapon right into Megatron's hands.
* In ''WesternAnimation/TheSimpsons'' episode "The Great Louse Detective" Homer needs a criminal to help him find out who is trying to murder him. Sideshow Bob is selected and a shock guard is taped to his ankle to keep him in line. Chief Wiggum tells him not to think about taking it off because it's taped to his leg hairs and that really hurts. Bob is about to kill Bart at the end of the episode (he threw the remote to his device out the window), but he can't bring himself to do it. As he leaves, birds outside peck at the remote.
* ''WesternAnimation/{{X-Men}}'' features collars that disable mutant powers.
* ''WesternAnimation/FamilyGuy'' with the FCC episode where they (in one instance literally) clung to Peter's ass, censoring and bleeping every (according to the FCC) distasteful thing that happened (including farting).
* ''WesternAnimation/{{COPS}}'' had an episode of LawfulStupid when Ms. Demeanor is arrested and sentenced to an experimental rehabilitation program, she is made to wear a mind-altering tiara.

[[folder:Real Life]]
* The medieval chastity belt, which, while a husband was away at war, prevented his wife from committing adultery with anyone but a locksmith. Either way, they were used in Hollywood more than real life, though some famous rulers sported them.
** There is no evidence they actually existed in the Mediaeval era - except symbolic ones that were usually string tied around the waist.
** This was even parodied in Robin Hood: Men in Tights.
** Male chastity belts, on the other hand, are not uncommon in the modern BDSM scene. They're designed to enable the wearer to urinate and go about his business more or less as normal, but not masturbate or sometimes even get an erection.
** These were also used in ye olde puritan days, where sex was considerably more taboo than it is now.
** The original concept for a chastity belt was as much rape prevention as it was for consensual sex prevention.
* Stun belts.
* House arrest tracking bracelets.
* [[ConeOfShame Those dorky plastic collars that stop pets from chewing out their stitches after surgery.]]
** [[WesternAnimation/{{Up}} "I do not like the cone of shame."]]
** It's even worse when you force it onto a cat. They get really depressed.
** Similarly, putting a collar with a bell onto your cat can prevent them from sneaking up on you.
* Creator/{{IBM}} had its flagship mainframe computer, the 360, designed in several models depending on how much the customer wanted to pay. When a customer ordered an upgrade from a low-end model to a higher-end one, all IBM did was send a technician out to ''cut one wire'' which then enabled the higher-level performance.
* Windows 7 (as well as several other programs) come with all features present, just disabled based on the level of license you have.
* [[http://en.wikipedia.org/wiki/Governor_%28device%29 Automobile engine governors]], to a degree. The [[CoolCar Bugatti Veyron]] has a [[http://en.wikipedia.org/wiki/Bugatti_veyron special key]] that must be inserted to permit top speed.
* Heavy trucks are often electronically governed. In the summer of 1997 Schneider National reprogrammed their truck computers via satellite. Suddenly you could top-out at 65mph instead of 55.
* Chemical Castration for pedophiles/rapists, intended to stop them from acting out their impulses.
* Much like the IBM "feature" above, back in the day, you could not have a dual Celeron CPU machine - unless you've "crossed some wires" via an adapter.
* Fuses and, more recently, circuit breakers.
* Clipping a bird's wings, thus removing their ability to fly.
* A guide dog is trained to treat its harness like one of these. When it's on, the dog is "on the job" and all other concerns are ignored.
* Cars in {{NASCAR}} are all fitted with [[http://en.wikipedia.org/wiki/Restrictor_plate restrictor plates]] at Talledega and Daytona, their fastest tracks, as a safety feature to limit the cars' top speed (without altering the drivers' techniques or the engine designs).
* Triple core processors are actually quad-core processors with one of the cores disabled. "Disabled" in this case does not necessarily mean "we took a perfectly functioning core and disabled it." It means "Good news guys, we can sell those chips where one of the cores doesn't work right instead of throwing them away." At least at first triple-core processors were intended and manufactured as quad-core processors, but had one core that failed quality testing.
* Some video games have gotten negative publicity from having functionality present on the disk but disabled until DLC unlocks it, most notably ''VideoGame/ResidentEvil5's'' multiplayer mode. Other games, such a ''VideoGame/GearsOfWar 3'', do the same, but with the unlocking DLC free, presumably as a post-release chance to iron out particularly tricky code.
* The "Super Go Karts" ride at Ride/ActionPark featured this: the titular karts had governor devices limiting their maximum speed to 20 miles per hour (that's 32 kilometers per hour for non-Americans). [[SubvertedTrope However]], the employees knew how to disable the governors by wedging tennis balls into them, and would do so for any curious parkgoers. [[RealityEnsues This did not end well.]]
* Most motors and powerplants have safety systems which will limit them (or shut them down outright) to prevent dangerous or unstable operating conditions.
* Some people, especially those in unusually high stress situations, tend to develop a restraining bolt of sorts over time as a way to keep their BerserkButton from working normally. Whether that item is an inanimate object, a person, a pet, or something known only to them varies from one person to the next. However, removing that bolt is a very good way to get them to come down on you '''''HARD'''''.
