The kiai is KungFoley done with your mouth. Often associated with stereotypical anime and MartialArtsMovie genre, the technique involves shouting, grunting or screaming while posing or fighting to audibly demonstrate your bone-crushing power. In some teachings, it is believed that the shout 'releases' your inner energy and allows you to use more force behind your blows. In reality strikes synchronized with exhalation are the strongest, regardless of sound.

''Kiai'' (Japanese for "unification of will", and pronounced like the words "key" and "eye" in rapid succession) is the technical term for the shout that accompanies kata (martial arts moves) in many real-life martial arts (and thus is TruthInTelevision). It serves partly as a battle cry, partly as a confidence booster at the moment you need to go all-out with an attack, and partly as a way to startle your opponent. Fighters are supposed to come up with their own kiai, though often it's simply "kiai." It's commonly seen in martial-arts films, anime, and really, anybody who's HotBlooded and kicking ass.

See also ScreamingWarrior, as well as FunnyBruceLeeNoises. Also see MakeMeWannaShout if a Kiai is weaponized.

!!Examples

[[foldercontrol]]

[[folder:Anime And Manga]]
* ''Manga/JoJosBizarreAdventure:'' "Wryyyyyy!" (pronounced "ree", to rhyme with "tree") is a battle-cry that many vampires use, though it is most famously attributed to BigBad Dio Brando and commonly parodied in fandoms (much like "[[TimeStop Za Warudo]]").
** Hero Jotaro Kujo has his own battle cry: ORAORAORAORAORA ORAAAAAAAAAAA!
*** This one is used in many anime. It is a sort of anime battle grunt, used mostly by the HotBlooded when they are striking multiple times consecutively.
*** [[Anime/FutariWaPrettyCureSplashStar Kintolesky]] also pulls it off, in a little moment of ActorAllusion.
*** [[Anime/TengenToppaGurrenLagann Kittan]] does it as well.
*** Likewise [=EnRyu=] in ''GaoGaiGar'', listen closely whenever he rapid-fires his weapon. It sometimes carries over to ChoRyuJin, too.
*** ...and Subaru Ryoko of ''MartianSuccessorNadesico''.
*** You can throw [[Franchise/SonicTheHedgehog Sonic the Werehog]] into this as well. [[http://www.youtube.com/watch?v=cAk8snYSt1k&feature=related Your evidence is here - just watch the QTEs]].
**** And in fact Knuckles the Echidna did it first in the Sonic Adventure titles.
*** [[LightNovel/HaiyoreNyarkoSan Nyarlathotep]] does both this and ORAORAORA as deliberate {{Shout Out}}s, since she's a massive {{Otaku}}.
** Dio's most famous and only face son, Giorno, also uses MUDA MUDA MUDA MUDA as his battle cry like Dio, he even uses the WRYYYYYYYY at one point.
* ''BambooBlade'''s Tama-chan uses this to stop one of her opponents cold, before executing a brutal [[spoiler: throat strike]] that counts as one of the highlights of the series. Especially impressive considering she's ''maybe'' half the size of the other girl.
* ''Manga/DragonBall'' is, of course, notorious for this, combined with TransformationIsAFreeAction whenever it's used for powering up.
** The Creator/FUNimation dub seems to take this [[UpToEleven even further]]... just check out Goku's Super Saiyan 3 transformation and then wonder how Sean Schemmel is still voice acting today.
*** The editing of the clip suggests some reuse of the best voice take-- but I still hope he got a few days off to recuperate.
*** In a behind the scenes feature of Dragon Ball Z, Sean Schemmel talks of how he passed out in the recording booth after this scene.
** Kiai is stated in [[AllThereInTheManual Daizenshuu 7]] a KiAttack used to knock away opponents or deflect attacks.
** Earlier, Tenshinhan uses a simple Kiai to dispel Cyborg Tao Pai Pai's [[KamehameHadouken Super Dodonpa]].
*** [[Manga/FullmetalAlchemist Vic Mignogna]] [[http://www.youtube.com/watch?v=tuwgQC6sUj0 hates this trope.]]
* [[PlayingWithATrope Played with]] in ''Manga/{{Bleach}}'' prior to the Soul Society arc by Orihime and Chad, who, while receiving training under Yoruichi to tap into their latent spiritual powers, initally believed that executing the trope was necessary.
** Of course, being a swordsman series, there are a lots of screaming.
* Used especially in the battle scenes of ''SoukouNoStrain''.
* Knowingly subverted in ''Manga/InuYasha''. Shippo, with a challenge from a strong opponent looming, asks InuYasha how to summon his powerful sword technique, the Wind Scar. Amused by the question, InuYasha replies with blatant lies, telling him he summons the power with chants of "Gagaga!" and "Dadada!". HilarityEnsues when Shippo tries to use it in battle.
* ''Anime/DigimonFrontier'' has the characters let out bloodcurdling screams for ''every'' occasion, going straight into the best (or worst - depending on [[SeriousBusiness your sense of humor versus your emotional investment in the show]].) {{Narm}} the franchise has to offer. It eventually reached the point where, when the main character got another [[EvolutionaryLevels Evolutionary Level]] near the end, the American voice actor actually refused to voice the new form - the strain of all the screaming that would be involved was more than he wanted to put his voice through.
** Ironically, during the new form's scenes, a comparitively smaller amount of screaming was actually involved.
** ''Anime/DigimonTamers'' did it first when Takato's wordless scream of determination actually rejuvenated his partner. When the other Tamers started copying him, Terriermon / Rapidmon asks "What's all the yelling about?"
* ''FistOfTheNorthStar'': Even beyond the classic (and arguably most famous of all incarnations of this trope) "ATATATATATATATAAAAAAAAA" of Kenshiro as he's unleashing the ''[[RapidFireFisticuffs Hokuto Hyakuretsu Ken]]'', a few of the other major characters do this to some extent, notably Rei and Raoh.
** Hyui's '''[[http://www.youtube.com/watch?v=BHbgoLFvpmE EEEEAAAAUUUUUAAAAHHHH]]''' deserves a mention.
*** In ''FistOfTheBlueSky'', the distant prequel to ''FistOfTheNorthStar'', Kenshiro does this as he's launching ''forks and butter knives'' into the skulls of the evil gangsters who were beating up his [[BloodBrothers sworn brother]] to try to get at him.
* [[HotBlooded Subaru]] of ''Anime/MagicalGirlLyricalNanoha'' is a frequent user of these in battle.
** Taken to another level when Subaru ''[[UnstoppableRage completely]] [[BerserkerTears lost it]]'' on Nove and Cinque. Sure, yelling can focus your attacks, but ''hysterical screaming and crying'' is just [[ScreamingWarrior that much better.]]
* ''Anime/TurnAGundam'' gave us [[LargeHam Harry Ord]] and his ''[[http://www.youtube.com/watch?v=1aKeU2NqWrE UNIVEEEEEEEEEEERSSSSEEEE!]]''
** Which, as usual, gets a ShoutOut ([[IncrediblyLamePun get it?]]) as [[http://www.youtube.com/watch?v=9DX_IaXs5YQ an easter egg]] in ''VideoGame/SuperRobotWars''.
** And in ''Manga/HayateTheCombatButler''.
** ''[[Anime/MobileFighterGGundam G Gundam]]'' is a much older example from the same franchise.
** There have been few fights HotBlooded Graham Aker of ''Anime/MobileSuitGundam00'' did not begin with one of these.
* Like [[MartialArtsAndCrafts many other things]], kiais are weaponized in ''Manga/RanmaOneHalf'': the devastating ''Yamasenken'' school (created by Genma, [[BunnyEarsLawyer of all people]]) typically opens by yelling "'''DON'T MOVE!!'''" at the top of one's lungs. It is powerful enough to stun not just seasoned martial artists like Ranma, but even rampaging ''bears''. It is at this point that the practitioner moves in with a tree-felling kick.
* In ''{{Eyeshield21}}'', many of the characters have a kiai. Kurita has "FUNNURABA!" (here I come), Monta has "MUKYAAA!" (literally a Tarzan yell), and Komusubi has "HUGOOOO!" Even Sena, who rarely seems like he enjoys it (although he does) develops a battle cry of "UOOOOOOO!" during the Christmas Bowl.
* In ''OnePiece'', Monkey D. Luffy usually does this whenever he delivers the final blow to his opponents, even so much that Creator/ChristopherSabat (Creator/FUNimation VA for Zoro) feels sorry for Colleen Clinkenbeard ([=FUNimation=] VA for Luffy) whenever he sees such a {{Kiai}} scene for Luffy, since Colleen will inevitably have to dub that scene later on.
** [[http://www.youtube.com/watch?v=JmgH-9Ll5P4&feature=related Not to say she doesn't do a hell of a good job on it regardless...]]
* ''Anime/NeonGenesisEvangelion'''s protagonist Shinji unleashes one of these the first time he dispatches an Angel. Except, instead of a HotBlooded roar of determination, it comes out more like an agonized scream of terror...which it kind of was.
** [[{{Tsundere}} Asuka]] plays the trope straight. Especially in ''End of Evangelion'' where she appears to be in [[AttackAttackAttack permanent Kiai mode]]; considering she just came out of a [[HeroicBSOD major nervous breakdown]] and [[UnstoppableRage needs to work off stress]], it's not surprising.
* In a somewhat bizarre choice by the current dubbing company for ''Franchise/{{Pokemon}}'', the dubbed version of Diamond & Pearl has gym leader Candice use this term multiple times.
* Used in ''Manga/{{Naruto}} Shippuuden'' by Killer-Bee, host of the Eight-Tails, such as after [[spoiler:he uses his [[WrestlerInAllOfUs Lariat]] attack to rip Sasuke open]], complete with using a hand held skyward to [[WardingGestures throw the horns]]. "'''WHEEEEEEEE!!!!!'''" (sounds better than it reads).
* It's more of a VerbalTic, but in ''KenichiTheMightiestDisciple'', Apachai Hopachai has a tendency to yell "APAPAPAPA!" constantly when he's fighting (or training, though [[TrainingFromHell he has a tough time differentiating between the two]]). Kenichi himself does this at one point when imitating Apachai.
* ''Anime/StreetFighterIIV'' is notorious for all the characters scream like maniacs while fighting. [[RuleOfCool What was pretty awesome for raise the level of emotion in the fights.]] Also, Fei Long gets even more infamous in the anime for his FunnyBruceLeeNoises.
* Lampshaded in ''Anime/FullMetalPanicFumoffu'' when Sousuke (as Bonta-kun) is training yakuza. He tells them to not waste movement and ''not'' to yell while attacking (this is all [[PokemonSpeak translated]] by Kaname).
* Akira Hibiki from ''{{Raideen}}'' will occasionally let out a loud "RAIIIII!".
* Used in, of all things, ''SmilePrettyCure''. Cure Happy literally screams "KIAI DA! KIAI DA! KIAI DA!" over and over to get her FinishingMove to work.
** [[spoiler:Ultra]] Cure Happy takes this UpToEleven in Episode 47, when she fires her massive BeamSpam against [[spoiler:[[BigBad Pierrot]]]]. She screams and gets ''louder'' and '''louder''' and '''[=LOUDER=]''' every second.
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/BirdsOfPrey'': White Canary uses this as she fights ComicBook/BlackCanary. See [[http://www.comicvine.com/white-canary/29-71585/all-images/108-388677/birds_of_prey__3_022/105-1299807/ here]].
* ''UsagiYojimbo'' - every fighter has their signature ''kiai''; Usagi's is "RYAAAAH!"
* The ComicBook/ImmortalIronFist has "K'ai!". He used it to the point where the K'un L'uns (the interdimensional people who trained him) began referring to him as Daniel Rand-K'ai.
[[/folder]]

[[folder:Film]]
* ''Film/{{Orgazmo}}'': [[TheDragon A-Cup]], [[{{Jerkass}} a not so subtle]] villain, porn-star, and martial artist does this gratuitously, especially before whaling on [[TheHero Joe Young]] numerous times. He happens to yell "key-yo" as opposed to [[TropeNamer "key-eye"]].
* ''Film/UndercoverBrother'' subverts this when Undercover Brother gets into fights. His kiais are all names of different black celebrities/musical groups (for example, in one fight he uses "Shaquille O'Neal", "Cisqo", and "Earth, Wind, and Fire" as kiais, all screamed in a high-pitched voice reminiscent of and/or in open parody of Bruce Lee or the blaxploitation kung fu stars.
* ''They Call Me Bruce'' (1982). A kung fu master tries to instruct Bruce in this technique. Bruce's shout ends up [[GlassShatteringSound shattering a nearby display cabinet]].
[[/folder]]

[[folder:Literature]]
* ''Literature/SisterhoodSeries'' by Creator/FernMichaels: Asian characters tend to yell "eyowww!" as they fight or cheer in this series, as can be seen in ''The Jury'' and ''Hokus Pokus''.
* In the first ''Literature/WarriorCats'' book, Firepaw tends to use "Gr-aar!" when attacking something.
* In ''Discworld/ThiefOfTime'', a monk tries to intimidate Lu-Tze with '[[FunnyBruceLeeNoises Ai!Shao!Hai-eee..]]' before learning his opponent's name. '[[OhCrap -Ai!Hao-gng? Ohsheeeeeohsheeeeeee..]]'
[[/folder]]

[[folder:Live Action TV]]
* ''Series/{{Andromeda}}:'' Possible subversion; While teaching Trance to fight, Tyr advises her to use a kiai to encourage proper breathing. She chooses "Hi-ho," which has the secondary advantage of incapacitating her opponents with helpless laughter.
* ''MysteryScienceTheater3000'' had a RunningGag of saying "HIKEEBA!" during parts of films where a Kiai would be appropriate. The cry originated in the film ''Film/{{Women of the Prehistoric Planet}}'', during a scene where the PluckyComicRelief shouts this before throwing himself to the ground.
* Miss Piggy of ''TheMuppetShow'' uses these alongside her trademark karate chops. She's usually silent when doing the follow up kick when her target has been knocked down.
* ''XenaWarriorPrincess'': Xena never leaps into battle without letting out a piercing cry of "LILILILILILIIIIIII!"
* Shows up a lot on ''Series/MightyMorphinPowerRangers'', especially from Tommy. BigBad Lord Zedd, after effortlessly trouncing the seemingly unbeatable Tommy, [[LampshadeHanging lampshaded]] his opponent's habit by asking: "Are all those hi-yahs really necessary?"
* ''[[http://www.youtube.com/watch?v=aQYpuINSXyE#t=11m24s "EUUAAAGH!" ]]''
-->-- '''Dex''', ''MaskedRider''
* Old-school ''Franchise/KamenRider'' and ''Franchise/SuperSentai'' series would have the heroes yell "Toh!" when jumping.
** The titular hero of ''Series/KamenRiderBlade'' does this quite often. Expect every other attack he launches to be punctuated with his unique yell of "UEEI!" Due to the fact that the show is something of a Japanese FountainOfMemes, fans have run away with it, replacing the final line of each verse of the show's first opening theme with Blade's {{Kiai}}, changing it from [[{{Mondegreen}} "BLADE! BLADE! BRAAAAAAAAAAAVE!!" to "UEI! UEI! UEEEEEEEEEEEEEII!!"]]
** ''Series/KamenRiderOOO'' yells "SEIYAH!" whenever he uses a finisher.
** [[Series/KamenRiderFourze Kamen Rider Meteor]] is also a frequent user. Justified as he's actually a martial artist, however.
** ''Series/KamenRiderGaim'' yells out "SEI-HAAAH!" as his finishing kiai.
** ''Franchise/PowerRangers'', being an adaptation of ''Super Sentai'', naturally uses this as well. Tommy Oliver's "SEI! HUYAH!" is probably the best known example, as it appeared in [[Series/MightyMorphinPowerRangers every]] [[Series/PowerRangersZeo series]] [[Series/PowerRangersTurbo he]] [[Series/PowerRangersDinoThunder did]].
* In an episode of ''CurbYourEnthusiasm'', Larry plays tennis with his wife, who grunts loudly whenever she swings. Larry complains that it sounds like "pigs fucking."
* ''Series/{{Ultraman}}''... SHUWATCH!
* The ''Series/MythBusters'' have never studied the effects of a kiai-style outburst on fighting ability, but they do play it straight from time to time when swinging weapons around or punching things (ForScience). Ironically while testing the efficacy of samurai armor, Kari noted that the urge to shout wordlessly while swinging a sword is almost involuntary.
* Mocked on ''Series/{{Eve}}''. Michelle, Rita and Janie's kung fu instructor insists that his profession is a silent art and they should go to a karate school if they want to scream.
[[/folder]]

[[folder:Music]]
* Used in the song ''Kung Fu Fighting''
* In the track preceding 'Karate' on ''Music/TenaciousD'''s first album ('Karate Schnitzel'), JB hits KG while yelling "Kiai!", because [[DisproportionateRetribution the bastard had eaten his schnitzel!]]
* The end of several tracks on Ugly Duckling's ''Audacity'' has a sample of a British guy dramatically narrating "the sound of the Kiai scream".
-->We promise to reveal the sound of the Kiai. Now listen, to the tremendous force of the scream. It is powerful enough...to kill.
-->''' '' EEEEEEEYYAAAAAAHHHH!!!'' '''
[[/folder]]

[[folder:Opera]]
* Creator/RichardWagner's Valkyries use the well-known cry "Hojotoho! Hojotoho! Heiaha! Heiaha!" in ''Theatre/{{The Ring of the Nibelung}}''. Naturally, their cry is a significant musical {{Leitmotif}}.
[[/folder]]

[[folder:Professional Wrestling]]
* Wrestling/YoshihiroTajiri has sometimes been heard making high pitched noises when he really gets into kicking someone.
* Wrestling/LowKi when delivering his ghetto stomp.
[[/folder]]

[[folder:Radio]]
* In ''FinalFantasyTacticsAdvance'' ''[[AudioAdaptation Radio Edition]]'', Marche does this against [[spoiler:Queen Remedi]].
* In the ''Radio/CabinPressure'' episode "Helsinki", Kieran shouts "Ki-ya!" while [[CurbStompBattle demonstrating to Martin]] that [[IKnowKarate he does in fact know karate]].
[[/folder]]

[[folder:Tabletop Games]]
* Orks in ''TabletopGame/{{Warhammer 40000}}'' are an innately psychic race; every one of them generating at least low-level psychic fields. The combined force of dozens or hundreds of orks charging into battle screaming at the top of their lungs actually makes them stronger. "WAAAGH!" is not just their BattleCry; it's their word for war--yes, the exclamation points are part of the word.
* ''TabletopGame/DungeonsAndDragons'' 1st Edition supplement ''Oriental Adventures''. The samurai class had a special ability: they could focus their ki and use a kiai (a loud, fierce shout) to raise their strength to superhuman levels for one round of combat.
* ''TabletopGame/{{GURPS}}'' has a skill specifically called Kiai. It requires the advantage Trained by a Master to use.
[[/folder]]

[[folder:Video Games]]
* ''Franchise/MortalKombat'':
** Liu Kang does this trope to death enough to make you fall off your chair laughing. He even does it when he gets hit, but stops that around Deception. There's a reason why he's the [[Pantheon/CombatIntermediateGods God of this]].
** Raiden applies as well.
* Thomas, the main character in ''Kung Fu Master'' (known on the NES as ''VideoGame/KungFu'') does this for all his attacks.
* In ''VideoGame/MegaManX4'', Zero does this when using the Z saber on the ground. He also does this when he unleashes certain special attacks.
* ''OsuTatakaeOuendan'' is all about Kiai. C'mon.
** The PC-based clone [[http://osu.ppy.sh/ osu!]] even has a special visual-enhancing mode ''called'' Kiai Time.
* Rishu Togo of ''VideoGame/SuperRobotWarsOriginalGeneration'' and all of his students (most famously, Sanger Zonvolt) all use the battle cry of "CHESTO!"
** Possibly as a ShoutOut, Van's battlecry in ''Anime/GunXSword'' is "CHESTER!"... which, with a Japanese accent, comes out "CHESUTO!" It's kind of a {{Narm}} in the English dub, where the original word comes through clearly.
** This particular cry is definitely OlderThanTheyThink, being used by Japanese martial artists and samurai. One of the oldest users in media is ''Series/KousokuSentaiTurboranger'''s [[TheBigGuy Youhei Hama/Blue Turbo]]. The series ran from 1989-1990.
*** ''Series/JukenSentaiGekiranger'''s [[TheBigGuy Ken Hisatsu/Geki Chopper]]. With a hand-blade.
** Other proud users of the 'CHESTO!' kiai includes [[VideoGame/EndlessFrontier Kaguya Nanbu]], [[Anime/MobileFighterGGundam Sai Saici]], [[VideoGame/ArtOfFighting Takuma Sakazaki]], [[SamuraiWarriors Shimazu Yoshihiro]], [[VideoGame/BlazBlue Bang Shishigami]], [[StreetFighter Makoto]], etc...
* Multiple characters in the ''Franchise/TalesSeries'' do this, usually when performing a [[LimitBreak Mystic Arte/Hi-Ougi]] or when activating the game's SuperMode.
** In particular, Stahn from ''VideoGame/TalesOfDestiny'' yells his head off before performing any of his many hi-ougis and uses a typical stance while doing it.
* Shofixti Captain Tanaka (and his twin brother Katana) in StarControl 2. With announcement: "And now I howl the scream of death! KYAIEEE!"
* Imperial Warriors in ''CommandAndConquerRedAlert3'' when using their special ability (pulling out their [[LaserBlade beam katanas]]) they will scream UIYAAAAAAAH!
* Shouts of this nature are the only "dialogue" Link, protagonist of ''Franchise/TheLegendOfZelda'' series, gets, other than "Hey!", "Com'on!" and [[ItMakesSenseInContext "Meow!"]]
* ''VideoGame/TheWorldEndsWithYou'': "Sine! Cosine! Tangent!"
* In ''Space Invaders Extreme 2'', all stages have their own music and sound effects for spawning, firing, contact, etc. In the most difficult stage, the music is high-tempo J-core and the firing sounds are loli-esque kiai.
* Fei Long from ''StreetFighter'' runs his status as a BruceLeeClone into the ground with his high-pitched shrieks every time he throws a punch. A [[Memes/StreetFighter running joke]] among the community is, "What does Fei Long love to drink? 'WA-TAAA!!'"
** The trope is openly lampshaded in VideoGame/StreetFighterIV, with [[AxCrazy Juri Han]] complaining about how Gei Long's screams are "like nails on a chalkboard".
* In the Wii version of ''PunchOut'', Great Tiger gets his own yell in his Title Defense version of the Mirage Dance, made even more epic due to the camera switching positions on him immediately following up with him creating a cyclone of illusions. '''SALZARAAAAAAAAH!'''
** Preceded by Dragon Chan in ''Super Punch Out!!'' who would shout a rather primitive kiai while delivering his (somehow legal) kicking techniques.
* ''TheWayOfTheExplodingFist'' is one of the earliest examples.
* ''VideoGame/SonicAdventure2'': TERIAAAAAA!
* ''VideoGame/DeadOrAlive'' has Jann Lee as possibly the single most annoying example in the game due to his BruceLeeClone status. The high pitched shrieks are just as present, and often punctuate the computer using him to counter perfectly and send half your health to the great beyond. On the other hand, they're also ''interruptible'', which leads to hilarious situations where you punch him in the face mid-attack. "WA-T-MMPH!"
** Hitomi has similar kiais that are more spread out. And by spread out, we mean they're associated with her more powerful attacks. Given this is [[CuteBruiser Hitomi]], this often means her distinctive kiai means someone's about to be launched a good twenty feet by the small cannons she calls fists.
* Being a [[HotBlooded hot-blooded]] martial artist, Mr. Champloo of ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'' is prone to yelling, both in and out of combat. When he has something important to say, or is arriving on the scene, he frequently makes himself known with a loud "Kiiiiiaaaaaaaaaaaaaaah!".
* Furio Tigre in ''VisualNovel/PhoenixWrightAceAttorney: Trials And Tribulations'', in keeping with his name, will outright roar when angry. At the end of the case, he roars so loudly he blows out the lights in the courtroom.
* [[DissidiaFinalFantasy CMONCMONCMONCMON! ONE MORE!!]]
* Soldiers in ''SilentStorm'' will unleash various kiai-esque cries when executing a long burst with a machinegun. As if it wasn't {{Badass}} enough already to fire a light machinegun on full auto whilst standing.
* Pretty much the whole cast of ''VideoGame/SengokuBasara'' feel compelled to do this, but the trope winner has to be [[ScreamingWarrior Sanada]] [[NoIndoorVoice Yukimura]], who shows off his impressive lung capacity EVERY FEW SECONDS!! [[SayMyName OOOOOYAKATA-SAMAAAAAAAA]]!!!!!
* The (first) default name for Ness's Favorite Thing in ''[[VideoGame/EarthBound Mother 2]]'', which just shows you what you already knew: Boys in Japanese media like nothing more than to [[Anime/DragonBallZ yell for seemingly hours on end]] before attacking.
* Balrog from ''VideoGame/CaveStory'' shouts "Doryaaaa!" in the original Japanese, often enough that it's his CatchPhrase. The FanTranslation rendered this battlecry as "Huzzah!", while the Wiiware version translated it as "Oh yeah!"
* Subverted in the VideoGame/NancyDrew game ''Danger By Design'', in that the villain's use of this trope actually gives Nancy clues about what attack the culprit is about to make, allowing the player to block each blow.
* Being a fighting game, ''VideoGame/TheKingOfFighters'' has TONS of this.
** Though many people ''hate'' Maximum Impact 2 (KOF 2006) with a passion, it can't be denied the Japanese version game has some really good Kiais. Kyo Kusanagi and Iori Yagami are good examples, as well as K' and Ryo Sakazaki.
** Kim Kaphwan, since day one of the series!
* Yoshimo from ''BaldursGate II'' does one of these when he lands a critical hit.
** After which he laughs. His other dialog suggests that he acts stereotypically 'Asian' because people find it interesting.
* A number of characters do this in ''VideoGame/BlazeUnion'', but Garlot is the worst offender--he even has a "screaming" dialogue portrait. It got to the point that when the opening movie was being made, [[Creator/KosukeToriumi his voice actor]] specifically requested that there be a scene with Garlot's kiai in there.
* In ''VideoGame/ShinMegamiTenseiIIINocturne'', the main character can learn a move like this. It more than doubles attack power when used. Sadly, there is no shouting sound effect, and it's simply called Kiai, and only in the original JP version. A more straight example might be War Cry, which decreases all enemies' attack power... by a whole freaking lot.
* In ''GuiltyGear'' we have Justice. "''[[ThatOneAttack SHAAAAAAAAAAAAA!]]''
* Most characters in ''SuperSmashBrosBrawl'' use Kiai.
* In ''VideoGame/FinalFantasyIV'', we have [[BareFistedMonk Yang's]] (and the rest of Fabul's monks') {{narm}}illicious "ACHOOOO!" Later translations restored their honor by making it simply "KIAI!"
* In ''VideoGame/PokemonBlackAndWhite'' [[spoiler:Alder literally screams "Kiai" just before the second time you battle him.]]
** However, it's first seen the first time you face Marshal of the Elite Four.
* In ''VideoGame/TheElderScrollsVSkyrim'', the PC is able to unleash special Shouts that have various effects, from sending the enemy flying backwards to dealing straight-up fire damage to freezing them solid.
** Also done when doing power attacks, both by the PC and others. Dremoras in particular do this in [[LargeHam over the top manner]] on every swing of their weapons.
* ''SuperMario64'': "YAH! WAH! '''''HOO!'''''"
* During battles in ''SkiesOfArcadia'', using the Focus option with any character results in a "haaaaaaaAAAAAHHHH!"
* ''VideoGame/TeamFortress2'' (or at least, the supplementary official comics): Soldier's "[[RunningGag HUTTAH! NECK SNAP!]]"
* In ''Mother 2'' (''VideoGame/EarthBound'' for those abroad), Ness' signature psychic attack is PK Kiai. This got changed to PSI Rockin' in translation.
[[/folder]]

[[folder:Web Original]]
* ''{{Tasakeru}}'': "BANZAI!"
* Chaka in the WhateleyUniverse actually uses this as an attack, screaming out "KIIIII-YAAAAAAAAH" in such a way that it stuns everyone nearby.
* Whenever [[ButtMonkey Ross]] appears in ''WebVideo/SteamTrain'' playthroughs, he has a habit of using a sharp, quick "kee-YAH" to punctuate his attacks.
[[/folder]]

[[folder:Western Animation]]
* In ''WesternAnimation/RoadRovers'', Colleen often did this, but in the form of pop culture references and various celebrity names (e.g., "Sharon...STONE!!!").
* Happens fairly often in ''TransformersCybertron''. Even [[PhysicalGod Primus]] uses it. While [[EpicFlail swinging moons he converted to maces]] at an enlarged-to-planet-size Starscream.
* Used occasionally while practicing by various characters in ''WesternAnimation/AvatarTheLastAirbender'', particularly [[PlayingWithFire firebenders]], since "power in firebending comes from the breath." It's somewhat less prevalent in actual combat.
-->'''Zuko:''' Now let me hear you roar like a tiger-dillo!
* In ''WesternAnimation/TheBoondocks'', Ed Wuncler III uses this when he's committing crimes.
[[/folder]]

[[folder:Web Comics]]
* In ''Webcomic/ElGoonishShive'', Ellen uses [[http://www.egscomics.com/index.php?id=457 "Yah!"]] and Abraham uses [[http://www.egscomics.com/?date=2009-07-08 "Kiai!"]].
[[/folder]]

[[folder:Real Life]]
* BruceLee popularized the kiai as part of kung fu films in the west, to the point that no over-the-top kung fu imitation [[FunnyBruceLeeNoises would be complete without his signature whooping]]. First-hand accounts of him actually fighting for real state that he was actually quiet.
* In traditional eastern martial arts, the Kiai is supposed to serve a variety of functions. The shout is supposed to increase the force of your blows. It also helps keep the fighter breathing during a fight. It expels all the air from the lungs, preventing you from getting the wind knocked out of you. It also flexes the abdominal muscles before a potential counterattack. It can also have a psychological effect on opponents, depending on the strength of the yell. Self defense classes generally advocate shouting when you're attacked in order to summon help.
* In kendo, kiai are actually required in matches in order to score, as it represents your intent to get the point.
* Occasionally seen in UsefulNotes/MixedMartialArts, though not that often. A notable example would be Joe Stephenson in his fight with BJ Penn. He loudly kiai'd with almost every strike he threw, leading to repeated shouts of "Arsh! Arsh! Arsh!" He lost.
* Seen in ProfessionalWrestling, though it's to hide the fact that they aren't really hitting each other. MickFoley would often yell "AH-SHA" and ReyMysterio would loudly yell "WAA-TAH" during strikes.
* Tennis players are known to shout with each swing, particularly the women. Unlike other examples, this is not generally used for distraction but rather to help the player exhale and swing harder, much like a weight lifter does when lifting large amounts. Although some of the loudest "grunters", such as Monica Seles (the measured sound level of her grunt, 93.2 decibels) or Maria Sharapova (''101'' decibels), have been accused of doing it to distract their opponent and cover up cues from the sound about what shot they're playing.
