Weapons that will cause the target they hit to lose consciousness for a certain period of time. Extra points if they cause a person to be mistaken for dead by a casual observer.

Unlike real world weapons made by Taser, which work by a very powerful electric shock, many of these show no clue to ''how'' they incapacitate a target, simply acting like a nonlethal version of the InstantDeathBullet. And like the TapOnTheHead often used for similar purposes, in fiction they almost never cause someone to be killed accidentally. In real life, Taser weapons have infamously caused several heart attacks, although they're still much safer than coshing or shooting someone. If they intentionally cause pain, can be an AgonyBeam.

Useful when ThouShaltNotKill is in effect. Ideal as FamilyFriendlyFirearms and often part of a NonLethalWarfare. However most authors don't seem to consider that even if the target is not directly harmed by the stun effect, there are many situations where suddenly losing consciousness could be dangerous.

Subtropes include InstantSedation (especially in the form of firearms firing tranquilizer darts), StaticStunGun for the electric-powered variant and SonicStunner for the sound-based version. Contrast AsLethalAsItNeedsToBe.

!!Examples:

[[foldercontrol]]

[[folder:{{Anime}} and {{Manga}}]]
* ''MagicalGirlLyricalNanoha'' has two types of damage: Physical and Magical. Physical damage can kill you, while Magical damage will only knock you out at most. The latter is the reason why Nanoha can [[DefeatMeansFriendship make friends by]] [[StuffBlowingUp blowing them up with a]] [[WaveMotionGun high-powered magical beam of pure energy]]. This works even when [[ThereIsNoKillLikeOverkill the entire area around you is destroyed]]. In TheMovie, Nanoha explicitly sets Raising Heart to stun.
* Several anime (''Anime/LostUniverse'' and ''Anime/{{Gasaraki}}'' immediately come to mind) treat rubber and plastic rounds this way, as somehow enacting the InstantDeathBullet without the death, rather than just ''hurting''.
* ''HigurashiNoNakuKoroNi'''s Shion Sonozaki has a habit of knocking people out with tasers, often by pushing it very hard into their ''neck''. She has never given anyone more than a few hours of unconsciousness (at least, [[TortureCellar that's all she's done with the]] ''[[TortureCellar taser]]''...).
** [[spoiler: However, she accidentally killed her grandma with it. Tasers don't go well with the elderly apparently.]]
* Several uses in ''GreatTeacherOnizuka''.
* ''TheSlayers'': Elmekia Lance is a weaked-down [[ReviveKillsZombie holy blast]] useful against things like demons and zombies. For what has been seen of its (usually accidental) use on humans, they tend to be knocked out cold. It's safe to assume the Ra Tilt does something similar, on a grander scale.
* Kanon Nakagawa, the neurotic IdolSinger from ''Manga/TheWorldGodOnlyKnows'' uses these in harmonious DualWielding, especially when she feels insecure about her status. That is, whenever [[{{Otaku}} Kei]][[TheCasanova ma]] ignores her.
* ''[[LightNovel/FullMetalPanic Full Metal Panic: The Second Raid]]''. Sousuke gives Kaname a taser weapon on her request, which she later uses to defend herself against an assassin in what most fans agree is her CrowningMomentOfAwesome.
* The Dominators in ''Anime/PsychoPass'' have a Paralyzer mode for targets whose Criminal Coefficients are between 101 & 300. Anything above that goes into [[LudicrousGibs Eliminator mode.]]
* In ''Manga/{{Toriko}}'' "Knocking" Guns fire needles to nonlethally bring down opponents. The catch is that the wielder needs to know the right nerves and pressure points to strike. "Knocking Master" Jirou and his grandson Teppei can perform Knocking with their bare hands.
[[/folder]]

[[folder:Comic Books]]
* At one point (probably not any more) the {{Punisher}} carried "mercy bullets" for use on interfering superheroes and bystanders. Spider-Man was once shot at point blank range with one; considering that even a blank can kill under circumstances like that...
* Blasters in ''StrontiumDog'' have a 'stun' setting in order to avoid harming civilians. In the "Bitch" story, Johnny ordered Red to keep her blaster set to 'stun' at all times as he was sympathetic to the Kaiak-K.
* The [[ImpossiblyCoolWeapon Lawgiver MkII]] in ''Film/JudgeDredd'' has a stun setting. However, it's notoriously unreliable and, as a result, [[ScrappyWeapon highly unpopular]] among street judges. They also have access to "Stumm" gas grenades, that incapacitate people through nausea, vomiting and other unpleasant symptoms - essentially current CS grenades on steroids - that unfortunately kill 1 in every 250 people affected so are only used in serious riots.
* After the SquadronSupreme forcibly disarms the nation as part of their Utopia Plan, law enforcement officers are armed with "Pacifier Pistols", guns that shoot small tranquilizer gels.
[[/folder]]

[[folder:Film]]
* The ''Franchise/StarWars'' universe is rife with stungun technology:
** Many blaster pistols in the ''Star Wars'' universe have a stun setting in addition to the kill setting (a feature commonly lacking in the FPS games). Without this, Leia wouldn't have made it through ''A New Hope''.
** Parts of the Franchise/StarWarsExpandedUniverse note various side effects. TheThrawnTrilogy, where Thrawn's forces are out to capture a pregnant Leia, reveals that they can't just stun her, since it sometimes causes miscarriages. In the XWingSeries Corran Horn is stunned and is conscious but paralyzed until it wears off, unhappily remembering that this happens to him sometimes when he gets stunned. [[OutboundFlight Survivor's Quest]] has the [[BadassCrew Aurek Seven]] stormtroopers checking someone they'd just stunned for heart palpitations.
** In ''Literature/{{Allegiance}}'', Mara Jade confronts a shady warehouse dealer who doesn't believe her when she tells him that he's not going to like the penalties for assaulting an Imperial agent. He orders his thugs to restrain her. One of them pokes her with the muzzle of his blaster just before firing; she twists around and uses the Force and some fancy moves to shoot all of the thugs, ending with the one who poked her, with that blaster, and aims it at the warehouse dealer. All very quickly.
-->''"Stun settings," she commented approvingly as the triple thud of falling bodies faded away. "So Pirtonna wasn't nearly as ready to play all-or-nothing with me as you are. Smart man. Means he gets to live through the night. What do you think ''your'' odds are?"''
** During ''Literature/GalaxyOfFear'', Tash wants an ActualPacifist to shoot someone with a blaster pistol set to stun, telling her that this wasn't breaking the rules of nonviolence, just bending them. In a later book, she takes a blaster from one of Vader's stormtroopers and uses it to resolve a SpotTheImpostor plot - and finds that it's set to stun.
* The already-absurd-in-many-ways Vin Diesel vehicle ''Film/XXx'' takes this particular trope to an absurd degree, with the movie's version of Q giving Vin Diesel a gun with an assortment of incredibly expensive "specialized" ammunition with various bizarre functions, including a highly complex bullet that not only knocks out its target with a harmless tranquilizer but contains a blood-squib to create the flawless illusion of an actual shooting to any witnesses. Vin Diesel, of course, is almost immediately [[PlotTailoredToTheParty given the opportunity]] to use these in a staged assassination.
* Since the premise is centered around law enforcement, ''Film/MinorityReport'' shows off quite a few nonlethal weapons. The closest thing they have to a stun gun is a gun that shoots a huge shockwave of air powerful enough to [[BlownAcrossTheRoom blow people across the room]].
** Another hilarious example is the Sick Stick. It's a nightstick that causes a person to ''instantly'' vomit. Of course, the question is, what if the person didn't eat anything?
*** He probably vomits gastric juice as in real life.
* The Psychlo handguns in ''Film/BattlefieldEarth'' have a stun setting, which they use to capture rogue humans for their labor camps.
** It seems like it's two weapons in one, especially since they use different barrels. The lethal mode is basically a HandCannon that can blow holes in a person's body. The stun mode shoots a green pulse that knocks out a target cold.
* The wimpy police in ''Film/DemolitionMan'' use "glow rods", which somehow use electricity to render the target unconscious. John Spartan is unimpressed when he has to confront Simon Phoenix armed with one of these, but he quickly discovers what happens when you add water to the equation.
[[/folder]]

[[folder:Literature]]
* For ''Franchise/StarWars'' examples, see ''Film'', above.
* DocSavage and his "mercy bullets" may have created this trope.
* Creator/LarryNiven's ''Literature/KnownSpace'' has mercy needles, slivers of [[InstantSedation anesthetic]] that dissolve in the bloodstream of whoever is shot with them.
* In Creator/LoisMcMasterBujold's ''Literature/VorkosiganSaga'', stunners are standard issue for police or anyone else who might want to be able to shoot first and ask questions later. Hangover-like symptoms are a nearly universal side-Effect, and at one point something like "we don't have to worry about heart conditions with this lot" is mentioned, implying that there is a risk of causing more severe damage than intended. She also points out a problem with stunners: If they're all you've got, then you can be killed by an unarmed mob, since they won't be afraid of attacking you, and with sufficient numbers they can overwhelm you, and kick you to death. If you were carrying a lethal weapon, they wouldn't dare try it.
* In Margaret Atwood's ''TheHandmaidsTale'', the Aunts wield cattle-prods.
* Creator/EEDocSmith's ''Family D'Alembert'' series (mostly ghostwritten by Stephen Goldin after Smith's death) features a stun gun with settings from one to ten. #1 is a mild shock that will sometimes not render the finest physical specimens immediately unconscious; #3 or #4 will put you out for up to an hour; #8 will put you down for many hours, and SOME victims suffer permanent neurological impairment; #10 is uniformly lethal. Weak or infirm victims may react worse to any given setting. Preferred by law enforcement because in moments of doubt you can shoot everybody and not worry about the consequences, but it backfires on them when the bad guys start using [[spoiler:humaniform robots]], against which they are ineffective.
* AndreNorton's science fiction stories had stunners, pistol-like devices that rendered their victims unconscious.
* Zoe of MatthewReilly's ''Six Sacred Stones'' uses one to incapacitate guards at Stonehenge.
* In SergeyLukyanenko's ''TheStarsAreColdToys'', the Russian government has managed to develop one-shot paralyzers that become useless after discharging with no way to recharge the battery. Unlike the typical examples of this trope, the target remains fully conscious but is incapable of movement. It is proven to work on at least one other race. Interestingly, the paralyzer is made by a think tank specifically charged with reading/watching science fiction for ideas. Their other known invention is an ExplosiveLeash.
* ''Literature/MarkDelewenAndTheSpacePirates'' has Officer Tirt ordering Mark to set his [[RayGun gun]] to stun. Justified, as he's a [[SpacePolice police officer]]; killing people he is supposed to be arresting would be frowned on.
[[/folder]]

[[folder:Live Action TV]]
* In the 1963 ''Series/DoctorWho'' serial "The Daleks", the Dalek's weapons are shown to have a secondary 'stun' function which is used on one of The Doctor's companions. However, it should be noted that the blast does not render him unconscious, it only temporarily paralyzes his legs.
** In their defense, Ian was pretty [[JustForPun stunned]] when they blasted him.
** The Fourth Doctor gets knocked out by such a weapon in "The Ark in Space". "Stun guns; I hate them."
** K9's nose blaster had a stun setting.
* In the episode "Meat", ''Series/{{Torchwood}}'' use stun guns against people who they don't think are dangerous. It turns out these people have guns and Ianto ends up tasering someone in the forehead, saying "Pray you survive." Indeed.
** Also used in the episode "They Keep Killing Susie."
--->'''Jack''': "This is for Ianto! Risen Mitten, Life Knife, and that old classic...[[{{Pun}} Stun Gun]]!"
* ''Series/{{Lost}}'''s Others have weapons similar to tasers, with multiple settings. They also have dart guns, whose darts inflict an electrical shock that can kill or merely incapacitate a victim.
* Phasers in the '''Franchise/StarTrek''' franchise developed with the times.
** [[Series/StarTrekTheOriginalSeries The original series]] featured a ''stun setting'' (which would handily knock out any non-[[SufficientlyAdvancedAlien godlike]] humanoid) and a ''kill setting'' which would [[DisintegratorRay make things go away]] (unless, again, the target was just plain immune). "The Man Trap" and "The Conscience of the King" featured lethal settings that left a body, [[BloodlessCarnage with no visible damage, as per typical television standards of the time]]. Something similar may have featured in "What Are Little Girls Made Of", when an [[RidiculouslyHumanRobots android]] has a hole shot in it, revealing its electronic workings. Ironically, this is the first episode to show disintegration. On the other hand, phasers also could heat rocks (or heat coffee) as a story might allow, which might have involved a special ''toast'' setting unmentioned in the canon media.
*** An intermediate "Heat" setting was mentioned in the [[Series/StarTrekTheNextGeneration TNG]] Technical Manual.
*** ''A Piece of the Action'' established that phasers having stun settings isn't limited to just ''guns'' -- Enterprise is entirely capable of non-lethal orbital bombardment.
** After ''[[Film/StarTrekVITheUndiscoveredCountry The Undiscovered Country]]'', it became canon that movie-era phasers on Stun could kill at point blank range (to the head). On occasion, phasers have been set to "maximum stun" when facing unusually tough enemies, which is implied to have a higher risk of killing someone.
** Scriptwriter guidelines for ''[[Series/StarTrekTheNextGeneration The Next Generation]]'' specified hand-phasers had about ten settings, from ''give someone a headache'' to ''vaporize a chunk of granite''. They started making marks on walls around 3 or 4. This was later expanded to sixteen settings, with level 3 capable of knocking an average humanoid unconscious for about an hour and level 7 treated as deadly force.
** Similarly, in one episode of ''Series/StarTrekDeepSpaceNine'', we see Miles O'Brien [[DrivenToSuicide contemplating suicide]]. He cycles the phaser through about five yellow settings and then five red settings to what we can only assume is 'Maximum Kill', if we go by the Technical Manuals, maximum setting (setting 16) on a phaser will vaporize both him and the entire room he's in.
** In the ''Series/StarTrekEnterprise'' episode "North Star" a mook from a primitive SpaceWestern society puts a revolver to T'Pol's head, holding her hostage. Reed simply stuns T'Pol, then the mook while he's still gaping at Reed's apparently ruthless action.
** In ''[[Series/StarTrekEnterprise Enterprise]]'', and sometimes ''[[Series/StarTrekVoyager Voyager]]'', phasers and similar weapons can be seen to have no effect ''at all'', maybe causing a slight limp from a shoulder wound (Enterprise pilot). [[FridgeBrilliance So they work a bit like electrolasers, maybe?]]
** Stun grenades, utilizing phaser technology, have also been featured in ''[[Series/StarTrekEnterprise Enterprise]]''.
** In the ''Series/StarTrekTheNextGeneration'' episode "The Hunted", certain humans in the military of the planet Angosia are altered to increase their fighting abilities, and are also resistant to phaser stun.
** In the episode "Encounter at Farpoint", ''Q'' of all people calls the ''Enterprise'''s bridge crew out on this by pointing out that there are species to whom even a phaser's "stun" setting could be potentially fatal. Granted, it's [[{{Jerkass}} Q]], but here [[JerkassHasAPoint he may just have a point]].
*** Apparently confirmed in ''Series/StarTrekEnterprise'', where it's revealed that Andorians, due to their higher metabolic rate are much more susceptible to phaser fire than humans. Even a graze from anything set above stun is potentially lethal to them, which a human could simply shrug off with some minor burns.
* ''Series/{{Alias}}'' uses "tranq guns" a lot (see InstantSedation).
* ''Series/StargateSG1'' also make use of Goa'uld-made semi-lethal stun guns, called "Zat'nik'tel" or "Zats": one shot will knock the target out (originally an AgonyBeam but no longer starting around season three), two shots are fatal, and three shots completely vaporize a body or a light object. The show's creators later regretted adding the third function, so the Zat never gets used this way anymore.
** There are also some training weapons called Intars. An intar is a close replica of another weapon, but with stun bursts instead of whatever the weapon normally fires, and is identifiable by a yellow light on the weapon. (This is because the war games were a know-your-enemy sort of thing; they were first encountered at a Goa'uld mock-up of an army camp, with all the soldiers given human names, etc.)
** And in ''Series/StargateAtlantis'', ''all'' of the Wraith's handheld weaponry are alien stun-guns. Justified in that the Wraith ''eat'' their human enemies alive, so they wouldn't want any wasteful deaths.
** Ronon's pistol also has various power settings, which at the lower end seem to act in a similar manner. Ronon [[OneManArmy being Ronon]] however, often has to be reminded to take it off of the [[TheresNoKillLikeOverkill highest kill setting]].
--> '''Sheppard''': That thing is set to stun, right?
--> '''Ronon''': *''{{Beat}}''* It is ''now''.
*** When Sheppard later encounters the Travelers, he finds out that they have the same weapons, implying that Ronon has somehow obtained a Traveler gun (or they both shop at the same arms dealer).
** The Bedrosians in "New Ground" also have staff-like weapons that fire a yellow knockout blast. Their shields also double as stunners.
** The Tollan, being {{Technical Pacifist}}s, equip their security personnel with triangle-shaped StunGuns.
* In ''Series/{{Firefly}}'', Alliance police officers generally carry some kind of concussion/stunning rifle that knocks people off their feet and leaves them dazed, though it doesn't appear to have any effect on inanimate objects like doors, as Jayne finds out in "Ariel" as he's trying to get the Tams out of the hospital before the Hands of Blue get them:
-->'''Jayne:''' ''Shee-niou'' high-tech Alliance crap!
** They're sonic weapons, at least according to [[AllThereInTheManual the RPG]].
*** Wow, the weapon designed not to cause collateral damage doesn't cause collateral damage.
** In the film, Simon also uses some sort of area-effect stun weapon disguised as a cane to knock out the scientists at the Academy. It appears to be a one-shot, though.
* ''{{Space 1999}}'' used laser Stun guns, which were called this despite a highly visible KILL option on the weapon.
* ''Series/RedDwarf''. A newsreader reports that "[[RuleOfFunny rubber nuclear weapons]]" (presumably the WMD version of rubber bullets) were used to suppress a riot over the latest virtual reality game.
** A simulant incapacitates the crew with a laser weapon for a period of three weeks. Somehow, this works on all four of them, considering two are flesh and blood, one is a droid and the other is a hologram.
* ''Series/{{Battlestar Galactica|Reimagined}}''. A flash-bang grenade is used to knock out Tigh and Adama during TheMutiny; this of course is a weapon developed for anti-terrorist use in RealLife.
* For the most part, the ''LawAndOrder'' franchise pretends that stun guns don't exist, seeing as they would suck the drama out of chases and stand-offs.
** To be fair, hitting a person while they run away with a taser (let alone a gun) isn't an easy perspective, and trying to take out a crook has a gun to a hostages head with something that makes them twitch a lot isn't the best of ideas. Also of note tasers aren't legal to own in New York.
* ''Series/TheTomorrowPeople'' used stun guns, due to the "Prime Barrier" preventing them from killing.
* On ''Series/{{Leverage}}'', Parker loves zapping people with various tasers and other stun guns.
** Her old mentor/father-figure has two nearly identical specialty canes, one extends a six-inch blade from the tip, the other acts as a taser. When a hacker makes some rude comments about Parker, [[PapaWolf the old man places his cane's tip against the guy's crotch and asks him if he'd like to find out which one he was using today]] (later, the same guy continues making rude comments so he hits him in the neck with it and discovers it was the taser after all).
* In an early episode of ''Series/BurnNotice'', Fiona zaps a Russian Mobster with a stun gun. However, since the mobster is currently grappling with her, the zap renders both of them unconscious. Note that in real life, stun guns neither cause unconsciousness, nor pass their current by physical contact with another person.
* The standard sidearm of a UEO naval officer in ''SeaQuestDSV'' is a sleek-looking energy pistol with a variable charge. The lowest setting ("green") stuns, while the highest ("red") blows stuff up spectacularly.
* Creator/JMichaelStraczynski explicitly forbid these from ''Series/BabylonFive'': "Stun settings are for people who can't commit." If you're fighting someone, either hit him or JustShootHim - if you're not, ''talk to him''.
** It's implied that a low-level PPG blast won't kill but will result in some nasty burns.
** Generally speaking, if Babylon 5's security personnel needed to take someone alive, they used old-fashioned batons or grappled them directly. The Minbari did have one or two high-tech methods of rendering someone unconcious, but even they typically would just club someone with a fighting staff.
* 1960s ''Series/{{Batman}}'' episode "That Darn Catwoman". Catwoman's goons use electric cattle prods to stun Batman into unconsciousness.
* The old and now almost unknown series ''Series/FireballXL5'' gave the heros a Coma Ray Gun, a non-lethal weapon capable of making most lifeforms fall into a deep, coma-like sleep for whatever period of time the plot required.
* Darien Lambert in ''TimeTrax'' is equipped with a Micro-Pellet Projection Tube, disguised as an ordinary car alarm keychain. Two of its buttons fire stun pellets (green and blue), which stun a person either for a few minutes or a few hours. The third button is for dosing the target with TXP, a drug required for TimeTravel.
* Lampshaded and averted (like several other sci-fi tropes) on the short-lived NBC series ''Something Is Out There''. The protagonists are being chased, so the cop tells his alien partner to set his weapon on stun and shoot them. [[WrongGenreSavvy She demands to know where he gets these silly ideas]]. Though this contradicts a scene in the premiere where his girlfriend picks up the female alien's stun gun and unknowingly zaps several people across the street.
[[/folder]]

[[folder:Radio]]
* Franchise/TheGreenHornet used a gas gun to [[InstantSedation knock out]] criminals (or anyone else he needed to shoot).
* Spoofed in ''Kremmen of the Star Corps'' with the Valium Ray. Also...
-->'''Karla:''' Should we set our lasers on stun?"
-->'''Captain Kremmen:''' No, this is serious. Set them on [[AgonyBeam Cringing Agony]]!
[[/folder]]

[[folder:Stand Up Comedy]]
* Eddie Izzard parodied this once in a routine about less and less damaging settings for Star Trek Phasers: "Limp," "Bit of a Cough," "Depression," "Bad Eyesight," "Ice Cream Van Nearby," "Sudden Interest In Botany," "Water In The Ear After Swimming," and "Left The Oven On At Home."
** By ''[[Series/StarTrekVoyager Voyager]]'', the default setting seems to be "mildly annoy".
[[/folder]]

[[folder:Tabletop Games]]
* "The List of Character Survival Techniques" ([[http://home.planet.nl/~jvdriel/survivaladvice.txt v.1.5]]) recommends carrying a stun weapon such as tasers and [[InstantSedation knockout poison darts]] -- sooner or later your teammate ''will'' catch DemonicPossession, HatePlague or something. And considering it as a primary weapon, to reduce [[HilaritySues inevitable]] [[CycleOfRevenge complications]].
* ''TabletopGame/{{GURPS}}: High-Tech'' has stun guns/batons as well as tasers, they're nearly useless against people wearing anything but normal clothing. By ''Ultra-Tech'' they've been replaced with [[LightningGun electrolasers]].
* ''TabletopGame/{{Shadowrun}}'' has stun batons, tasers, stun gloves, etc.
** One of the provisions of Dunkelzhun's will is a large sum of cash for the developer of an effective, safe, stun weapon. 15 in game years later, there is still mention from time to time of companies trying to win that prize.
** This is possibly a nod toward GameplayAndStoryIntegration. The rules of the game allow for two separate [[HitPoint damage tracks]]: Physical and Stun. As the name implies, Stun weapons cause Stun damage, but so do things like physical exhaustion (from a long day of work), powerful medications, and [[CastFromHitPoints casting spells]]. Taking Stun damage in excess of your Stun track will instantly knock you out, but the overflow carries over to physical damage where it is cumulative with existing wounds; if you were about to pass out from stress anyway (9 boxes out of 10 on the Stun track) and had a couple of light Physicals wound (2 boxes out of 10 on the Physical track) and you get hit with an instant-KO shot (10 boxes out of 10 on the Stun track), the Stun overflow can push through and kill you outright.
* TSR's ''Star Frontiers'' game had electrostunners (ranged stunning weapons).
* A relative of the above FASA property, the tabletop ''MechWarrior'' RPG features a variety of stun weapons. [[InstantSedation Chemical]], [[StaticStunGun electrical]], and [[SonicStunner sonic]] stun weapons are available as ranged weapons, though stun batons are also available. An insidious item known as the neural whip could also technically be used to stun victims, but prolonged use could result in crippling injuries and permanent loss of attribute points.
* Believe it or not, the normally ultra-lethal ''TabletopGame/{{Paranoia}}'' has stun guns, along with tanglers (which strangle you to death if you get hit in the neck, otherwise they just immobilize a body part).
* ''TabletopGame/EclipsePhase'' has stunners, electrolasers that deal some damage and the "shock" status effect, shock batons, shock gloves, and [[BioAugmentation eelware]] are melee weapons that do practically the same thing. Also [[AgonyBeam agonizers]] use microwaves to inflict incapacitating pain without damage (unless set to "roast"), and standard laser guns have a "stun" setting that uses a set of quick pulses to achieve a flashbang-like effect.
[[/folder]]

[[folder:Video Games]]
* ''[[VideoGame/MetalGearSolid2SonsOfLiberty Metal Gear Solid 2]]'' saw Snake infiltrating the tanker armed only with a modified Beretta M9 designed to fire anesthetic darts. Suitable weaponry for infiltrating a tanker filled with loyal US Marines, less suitable weaponry for infiltrating a tanker now filled with faceless terrorists.
** Ironically, the lethal weapons were almost universally outclassed by the M9 since it's perfectly silent, and enemy soldiers finding unconscious guards didn't sound an alarm. Not to mention in most cases you only needed one dart per guard; a soldier hit in the arm by the M9 would walk around for a bit [[InstantSedation and then fall asleep]]. A soldier hit in the arm with lethal weapons would sound an alarm and return fire.
*** It's less useful on higher difficultly settings, as the effect wouldn't last all that long. It's more useful for gaining [[GottaCatchEmAll dogtags]], however - a tranquilized guard's tags can be stolen once he wakes up, a dead one's are off-limits until you go far away enough from the room he's in that he respawns.
** Later in the game it's possible to find a "[=PSG1-T=]", a version of the SniperRifle that fires tranquillizer darts, and the end game [[KatanasAreJustBetter high-frequency blade]] has a stun setting (beating people with the blunt side of the blade, presumably). These exist solely to enable {{Pacifist Run}}s.
** In [[VideoGame/MetalGearSolid4GunsOfThePatriots the fourth game]] you have a Ruger Mk II and can unlock the [[VideoGame/{{Boktai}} Solar Gun]], which is unable to damage anyone (except Vamp) but is ''very'' good at stunning and knocking down opponents.
*** In the fourth game, you have a stun ''[[UpToEleven knife]]''. You can also stun people by sneaking up on them with Metal Gear Mk. II and smacking them with its manipulator.
** [[VideoGame/MetalGearSolid3SnakeEater The third game]] (and its sequels ''VideoGame/MetalGearSolidPortableOps'' and ''VideoGame/MetalGearSolidPeaceWalker'') had the Mk22 and Mosin Nagant. The latter is also in ''[=MGS4=]'', and ''Peace Walker'' also has a stun rod in place of ''[=MGS3=]'''s knife, as well as a shotgun that fires rubber slugs.
** ''[[VideoGame/MetalGearSolidVThePhantomPain Metal Gear Solid V]]'' gives us the Wu Silent pistol, which is the silenced tranquiliser pistol that's been a staple of the series since ''MetalGearSolid2'' and the Urugan-5, which fills the role the Rubber Slug Shotgun did in ''Peace Walker'', except as [[RevolversAreJustBetter a 5-shot revolver]].
* In ''VideoGame/UrbanChaosRiotResponse'', if you taze someone for too long they will burst into flames, killing them.
** The same happens in the ''VideoGame/SyphonFilter'' series.
*** [[http://news.aol.com/article/man-catches-fire-after-being-tasered/580031 The same thing has happened in real life, too.]]
* ''VideoGame/DeusEx'' was coded to react differently based on the lethal force the player used. In the immediate sense, death screams were louder than anything short of an explosive, judging by AI reaction to noise. More long term, some [=NPCs=] liked taking prisoners or avoiding combat, some liked to shoot things. The game featured a silent 'minicrossbow' that fired tranquilizer darts, a riot prod that looked like a stun gun on steroids with a healthy dose of [[TimTaylorTechnology More Power]], and tear gas. There was also a baton which was mainly used for one hit knock out if you could sneak up on someone from behind, though it could be used for a frontal assault if the player was inclined to commit suicide by actually trying to use it on an enemy firing back. The game was inconsistent when determining the casualties caused by the player, however, occasionally marking the player as overly violent because of how many targets had been 'removed' from combat rather than how many had been killed outright.
** Many players tried to manage {{pacifist run}}s with these tools, though the first game forced one kill, unless exploits were used, and the second game had common high-end mooks that couldn't be knocked out. The third game was more forgiving and actually rewarded players for leaving everyone alive.
** The sequel ''[[VideoGame/DeusExInvisibleWar Invisible War]]'' kept these weapons, although the electric prod became worthless while the simple plastic stick is absolutely terrifying in close combat. Also added was a player-controlled drone that could self-destruct with an electric stun blast. Two drones would down most enemies. A definitive game breaker in that the player could easily find a source of unlimited power in most maps from which all enemies could be neutralized without any danger to the player.
** The prequel ''VideoGame/DeusExHumanRevolution'' has two of its non-lethal weapons in this vein: one (the Buzzkill) fires a shock dart, causing the target to twitch for a few seconds and quietly collapse. The other one (the PEPS) fires a concussion wave that can knock out several targets, although, unlike the shocker, a knockout is not guaranteed. The game also allows the player to knock out target with a well-placed punch or a choke-hold (depending on the animation) or to use the landing system. That or use the tranquilizer rifle.
* The ''VideoGame/{{X-COM}}'' series has many weapons that only cause stun damage so you can collect live aliens. The first game started the player off with the melee-only Stun Rod, which was of at best limited use aside from an occasional attack of opportunity, while the other side had a sort of TechnoBabble-powered flashbang fired from a small grenade launcher. ''Apocalypse'' addressed this by providing the taser-like Stun Grapple and Stun Gas grenades.
** The Stun Rod's ''Terror From The Deep'' equivalent, the Thermal Taser, is incredibly useful for one reason: Lobstermen, which are [[NighInvulnerability nigh-invulnerable]], take full damage from the Taser. Since the only other weapon that does full or more damage to Lobstermen is the equally short-ranged [[{{Vibroweapon}} VibroBlade]] weapons, the Taser can be useful if you encounter Lobstermen before you've researched either the blades or the Thermal Shok Launcher.
** The Firaxis [[VideoGame/XCOMEnemyUnknown remake]] replaces the Stun Rod with the Arc Thrower, which must be researched first after performing an autopsy on an alien (which determines that their central nervous system is similar to ours). The Arc Thrower is not a melee weapon, but it must be fired at a very close range. The basic Arc Thrower only has a 70% chance of working, though, and you only get 2 shots with it per mission. Once you build the Foundry, you can upgrade the Arc Thrower to have a higher chance of stunning an alien (and also make it work on new types of aliens). The weapon is best used by the Assault class who have the Lightning Reflex ability, allowing them to dodge the first alien Overwatch shot (i.e. they can run up to the enemy and use the Arc Thrower without being shot).
* In the ''VideoGame/SplinterCell'' series, Sam's rifle fires a variety of knock-out weapons, including electric bullets, airfoil rounds (which work via [[TapOnTheHead blunt trauma to the head]]), and gas grenades. ''Chaos Theory'' has a level where the enemies are equipped with the airfoil rounds. Sam correctly identifies these as [[InsistentTerminology "Less-Than-Lethal"]] weapons; they are definitely ''not'' non-lethal.
** Also in ''Chaos Theory'', the captain of the ship in the second mission actually ''dies'' if you try to knock him out (presumably from a heart condition or something). It doesn't count as a kill in your mission stats, but if you look at his body in thermal vision you can see it cooling down to corpse temperature.
* ''VideoGame/{{Xenogears}}'' has [[TheGunslinger gunslinging]] Jesiah Black use "stun bullets" once, with no further elaboration.
* In ''VideoGame/{{Metroid}}: Zero Mission,'' Samus is shot down on her first attempt to escape Zebes; in the crash, she loses her armor and has to infiltrate the Space Pirate mothership armed with only a stun gun. The gun has a ridiculously long recharge time, and it only stuns enemies if fired with a full charge; otherwise it just ticks them off. Worse, enemies shot with a full charge only stay stunned for three seconds, after which they wake up and sound the alarm, assuming Samus isn't hidden when they do wake up (which, given the above, is rather difficult to actually manage). Samus herself [[LampshadeHanging lampshades]] the gun's many failings in monologue:
--> "All I had for protection was my rather useless emergency pistol..."
* Done realistically in a mission for ''VideoGame/CommandAndConquerTiberianSun'', in which your GDI riot troops are equipped with rubber bullets to put down protests. Using one causes protestors to give up and go home, while using too many will kill the target (and lose you the mission).
** Again in ''VideoGame/CommandAndConquerRedAlert2'', the training levels have your troops clearly shooting at other Allied troops, with the justification being that everyone on the field is using rubber bullets.
* ''VideoGame/{{Oni}}'' has the Van de Graf pistol, which fires a short-ranged bolt of electricity to briefly stun enemies. It does no damage, but gives time to position oneself for a [[BackStab Backbreaker]] or other hand-to-hand attack.
* ''Videogame/{{Fallout 3}}'' features the [[http://fallout.wikia.com/wiki/Mesmetron Mesmetron]], an experimental weapon that has a 50% chance of stuning someone, a 30% of making them very angry and a 20% chance of making ''their head explode.''
* ''VideoGame/SWAT4'' features the full range of ''less lethal'' weapons at the disposal of major metropolitan police forces in the US, including CS grenades, Stinger grenades (fragmentation with rubber schrapnel), tasers, pepper spray, beanbag shotguns[[note]] actually, beanbag ''cartridges'', but they're loaded into designated less-lethal shotguns painted green to avoid confusion.[[/note]] and paintball guns loaded with pepper balls. All this gear is ''necessary'' to achieve high or even qualifying scores, since every casualty, suspect or victim, counts against your final score.
* ''VideoGame/NoOneLivesForever: A Spy In H.A.R.M.'s Way'' features an electric stun gun (the hand-to-hand kind) and a CT-180 utility launcher that can be loaded with [[InstantSedation tranquilizer darts]] which will both quickly and [[StealthBasedGame quietly]] take down opponents, leaving them alive. Sadly, they recover inside only a few minutes, and then will manifest weapons (even if searched and disarmed) shortly after that, providing an incentive to take out opponents in a more lethal fashion.
* The only weapon you get in ''VideoGame/{{Hydrophobia}}'' is a stun gun, you're meant to use it to keep enemies at bay while you use the environment to kill them but oddly for this trope it can kill if you shoot it enough times....or change the ammo to something more lethal.
* In ''TotalAnnihilation'' the Arm Spider unit is armed with a stunner, although this is more probably a weapon to disable ''technology''. The spin-off ''TotalAnnihilationKingdoms'' has magical stun weapons used by Aramonian Mage Archers and Verunan Lighthouses. Interestingly, the logo for the stun arrow is an arrow with a pair of magically glowing handcuffs wrapped around it.
* In the later ''VideoGame/CommanderKeen'' games, your weapon is the Neural Stunner. Most enemies stay "stunned" permanently, but some revive after a few seconds.
* ''VideoGame/{{Thief}}'' has the Gas Arrows, which do not do any damage but will instantly knock people unconscious, regardless of how alert they are. Given how incredibly useful this is in this game, they are quite rare.
* Inverted in "GrandTheftAutoChinatownWars". The player can purchase a "Teaser", which shocks your target for as long as you hold the trigger. Hold it too long, though, and they'll [[VideogameCrueltyPotential burst into flame]], instantly giving you a one-star Wanted level.
* Weapons called "Stun Rods" appear in the hands of late-game mooks in''VideoGame/ResidentEvil4'' and ''VideoGame/ResidentEvil5''. It's a bit of a misnomer, though: in 4 they do about the same amount of damage as being shot in the face with a [[GatlingGood Gatling Gun]], and in 5 they instantly put you into [[ControlledHelplessness Dying status]]. You can also buy a Stun Rod in 5 and use it yourself; it is extremely powerful and works wonders for crowd control and best of all [[AwesomeYetPractical it doesn't use any ammo.]]
* [[spoiler: Manfred von Karma]] from ''VisualNovel/PhoenixWrightAceAttorney'' uses a taser to knock out Phoenix and Maya.

[[folder:Web Comics]]
* In ''WebComic/GirlGenius'', Baron Wulfenbach's revenant containment troops are equipped with stun bullets and C-gas grenades, for non-lethally subduing mind-controlled civilians. Tarvek gets shot in the back -- at point blank range -- with a stun bullet, and survives; he shows up in Castle Heterodyne.
* In ''TheLydianOption'', the Tha'Latta carry long rods with tasers at the end to subdue unruly prisoners.
* ''Webcomic/SchlockMercenary'' has "difference-tone stunners", summarized [[http://www.schlockmercenary.com/2000-09-03 here]]:
-->'''Kevyn''': ''It projects two parallel, unidirectional, high-amplitude '''VHF audio streams''', with slightly differing frequencies. When those streams intersect a target, a high amplitude '''difference-tone''' is generated in the body of the target. This low-frequency tone interferes with the target's '''synaptic refresh''', effectively jamming the nervous system and rendering the target instantly unconscious. ({{Beat}}) It's a '''magic sleep gun'''.''
** They're actually disdained by the mercenary company per se, as they are useless for intimidation.
* In ''Webcomic/SluggyFreelance'' Riff subdues a [[DemonicPossession demon-possessed]] Gwynn by using [[http://www.sluggy.com/daily.php?date=000528 the stun setting on his laser cannon]]. Given [[TimTaylorTechnology Riff's]] [[MoreDakka personality]] the fact that a weapon he built has a stun setting [[http://www.sluggy.com/daily.php?date=000531 surprises everyone]].
-->'''Torg:''' I'm surprised the switch didn't rust over by now!
** Later parodied (along with TheDogShotFirst) in [[http://www.sluggy.com/daily.php?date=080503 this]] strip.
* In ''Webcomic/{{SSDD}}'' Norman favors a [[http://www.poisonedminds.com/d/19990208.html cattle]] [[http://www.poisonedminds.com/d/20051014.html prod]] that tends to act like a stun gun.

[[folder:Western Animation]]
* In the 90s [[WesternAnimation/{{X-Men}} Marvel]] [[WesternAnimationSpiderManTheAnimatedSeries cartoons]] and various other action shows, [[FamilyFriendlyFirearms energy weapons]] on low settings are treated this way.
* In the ''JonnyQuest'' episode "The Robot Spy", the title device had two antennae that could render anyone they touched unconscious.
* ''GIJoe'', one of the granddaddies of FamilyFriendlyFirearms, actually showed this... only twice. Once when a character was hit by a laser during a training exercise (and failed to be actually ''stunned'', merely yelping in pain), and once during a closeup of a Joe setting the power slider on a pistol ''from'' "stun" to "max." ATeamFiring seemed to be their preferred form of less-lethal attack.
* The season 3 finale of ''{{Archer}}'' features "ion pulse" weapons that are supposed to be this. In a bit of a deconstruction, they actually stop your heart and affected persons need immediate defibrillation ("So... 'stun' may be a bit of a misnomer"). Naturally, this doesn't stop [[JerkAss Archer]] from shooting his co-workers with them anyway.
* Spectrum-issue sidearms have a stun setting in ''WesternAnimation/GerryAndersonsNewCaptainScarlet'', which is a mild {{bowdlerisation}} from [[Series/CaptainScarletAndTheMysterons the original 1960s version]]. It is ''mild'' because they also have a clearly-marked KILL setting which appears to be the default, and the on-screen body count is not noticeably lower.

[[folder:Real Life]]
* Weapons that render a person unconscious, or incapacitate without causing permanent injury, are rare in real life. The sad fact is that the amount of force necessary to knock a person out is almost as great as the amount of force necessary to kill a person, and it's very hard to hit hard enough to do the former without hitting ''so'' hard that you also do the latter. Additionally, a certain amount of force may work to stun one person, but would not faze another, or be enough to kill yet another.
* Several companies are working on electrolasers, effectively taking the awkward probes and wires out of the Taser by using a high-frequency laser to ionise a path through the air for current to follow. So far, they've developed effective [[BoobyTrap area-defense]] devices, although they're still a long way from pistol or even rifle size.
** The development problem is, as per all beam weapons, a portable power supply.
** Another problem with electrolasers is that laser beams powerful enough to ionize air between them and a target are usually powerful enough to ''[[FrickinLaserBeams make holes in it]]''. Which kinda defeats the purpose of having them in the first place.
*** Raw power (i.e. the number of photons) is not the issue, but frequency. Each photon must be able to kick off an electron on its own, so what's needed is a fairly modest beam in ultraviolet. This also contributes to the size problem--there is no simple, stable lasing medium that works in that band, necessitating more complicated and bulky designs.
** There are also a few designs using concentrated jets of salt water, but they face the same issue as peeing on the third rail, lack of a coherent stream.
* Riot level pepper-spray guns (also used to ward off bears) count as something between StunGuns or chemical [[AgonyBeam Agony Beams]], with better takedown statistics but shorter range than handguns. Sadly, their extracurricular use in back-room [[PoliceBrutality police interrogation]] is on the increase.
* Another tool used by riot control police is the "riot ball". This is a big rubber bullet designed to be fired from a shotgun. It will cause a big bruise, and maybe crack a rib, but its intent is to incapacitate its target, not kill it.
** Certain countries with anal gun control laws, such as Russia, encourage the production of "traumatic" weapons, that is, stun firearms that can only fire rubber bullets. Most of them are either notoriously ineffective or needlessly lethal, with civilian versions likely to be the former and police versions the latter.
* The ''Series/MythBusters'' once took on the notion of a water-based stun gun, with some success. However, they determined that the device they created was, in fact, more likely to kill anyone you shot with it than to stun them.
** Another note, they could only make it work at all was to fire it from inside giant, specialized lightning generator, and they only had one shot.
* The [[http://i.imgur.com/ISjUL.jpg Taser XREP]] (eXtended Range Electronic Projectile) is perhaps the closest there is to a effective multi shot stun gun. Its essentially a miniaturized taser that fits a 12 gauge shotgun. It deploys on contact so its effective range is about 100 feet, more than double to the current stun guns used by police officers. The only real problem with it is that currently its quite pricey at around $100 a round (if you buy a pack), luckily the shells are reusable.
** And if you liked that, you're gonna love the [[http://www.taser.com/products/law/Pages/ShockwaveLE.aspx Taser Shockwave]]. Call it what they will, I call it a Taser Claymore. (No, not [[{{Claymore}} that kind]], although that would also be awesome. [[http://en.wikipedia.org/wiki/M18_Claymore_anti-personnel_mine This kind.]])
** Taser shotguns caused controversy recently when they were used by British police on fugitive gunman Raoul Moat, who then [[AteHisGun killed himself with a sawn-off shotgun]]. The controversy arose from the fact that apparently the Home Office hadn't approved their use, as they're still under testing.
* Stun guns are "pain compliance" weapons. They do not render people unconscious, nor even physically incapacitate them (admittedly, they can cause muscles in the targeted zone to lock up, briefly). Another problem with stun guns is that they require skin contact, and have no Taser-like barbs to penetrate clothing. It is necessary to press both prongs of the stun gun onto skin to complete the circuit and enable the current to flow.
