* One of ''Anime/MazingerZ's'' best attacks, the Rust Hurricane. Mazinger blows a jet of particle-charged wind from its mouth grill that corrodes the enemy into nothingness. Its successor ''Anime/GreatMazinger'' has the Great Typhoon, which is the same thing but without the rust effect, while SuperPrototype ''Anime/{{Mazinkaiser}}'' has the Rust Tornado, an UpToEleven version of Mazinger's attack.
** Many {{Robeast}}s from ''Anime/Mazinger'', ''Anime/GreatMazinger'' and ''Anime/UFORoboGrendizer'' have breath-based attacks, usually expelling out fire, acid or even poison. One of the seven armies of Mykene Empire (the Reptilian Warbeasts) specialized in this kind of weapons.
* Most beam attacks in ''Anime/{{Pokemon}}'', such as Hyper Beam and Aurora Beam, work this way. Pokemon that lack a Breath Weapon have attacks that emerge from other body parts (get your mind out of the gutter; we're talking about hands, pincers, [[ShoulderCannon shell-mounted pressure cannons]]...)
* ''Anime/DragonBallZ'', but villains most times. Notably Nappa, Piccolo and Cell (whose use of this trope inspired the [[MemeticMutation Internet memes]] "IMMA FIRIN' MAH LAZER", "SHOOP DA WHOOP", and [[TheLazerCollection Dr. Octagonapus]]).
** Frieza, the ultimate BigBad, also used a variant of a breath weapon to gain access to Saichourou/Guru's hut before Nail distracted him & [[HeroicSacrifice lured him away to fight]].
** Any Saiyan in his [[OurWerewolvesAreDifferent humongous were-monkey]] form. ''GT'' also gives them fire-breathing powers for some reason.
** Taken to the logical extreme with Recoome from the Ginyu Force, who gets shut down (literally) by Krillin upon attempting this on a wounded Vegeta, and blows up nearly all his teeth in the process.
** In a technological variant, Sergeant Metallic (aka Major Metallitron) has a missile launcher in his mouth.
** And in a particularly hilarious example, Super Buu uses a mouth beam to badly scorch Gotenks, and laughs at him. He's shut up rather quickly when Gotenks opens up wide and delivers the same attack back at him.
** Ironically, the most horrifically dangerous breath weapon in the series is used by Dai-Kaio ([[KingOfAllCosmos the highest of all the Kais]]), described as one of the cheeriest and most benevolent beings to ever live. If hit by it, the recipient is immediately ''diced'' and then blown up. Supreme Kai notes that that attack would be a OneHitKill on anyone other than Buu, who can regenerate indefinitely. BewareTheNiceOnes indeed...
* Several of the Boomer robots from ''BubblegumCrisis'' had beam cannons hidden in their mouths.
* ''Anime/MobileSuitGundam'' had the Zeong. This attack was the one that finally did in the titular mecha, the Gundam.
** Many subsequent series also had MS capable of shooping the whoop, such as ''[[Anime/MobileSuitGundamZZ Gundam ZZ]]'''s Zaku III & the Destroy Gundam from ''[[Anime/MobileSuitGundamSeedDestiny GundamSEEDDestiny]]''. The original series also had the Zakrello, [[FanonDisContinuity but we don't talk about him...]]
** The ''[[Anime/MobileSuitGundamF91 F91]]'' and ''[[Manga/MobileSuitCrossboneGundam Crossbone]]'' Gundams have a heat vent in place of a "mouth", usually covered by the faceplate. It isn't really intended as a weapon, but if their "overheat" mode activates at point-blank range, the sudden blast of intense heat from the mouth has been shown to damage mobile suits.
* The Menos Grande and some of the Arrancar of ''Manga/{{Bleach}}'' do this with their Cero attacks. Nnoitra has a slightly creepy variant: he fires his from the tip of his very long tongue. Ew.
** Nelliel can eat Ceros and [[BreathWeapon fires]] them back with the combined force of her own Cero, this technic is called Cero Doble.
** Taken further by the Espada Baraggan Louisenbairrn, [[spoiler:whose "[[ExactlyWhatItSaysOnTheTin Respira (Death Breath)]]" will cause [[HoistByHisOwnPetard anything]] it touches to rot into nothingness.]]
* Several ''Franchise/YuGiOh'' monsters do this, most notably The Winged Dragon of Ra.
** Parodied with Exodia in ''WebVideo/YuGiOhTheAbridgedSeries''
** There's also the well-known Burst Stream of Destruction / White Lightning from Blue-Eyes.
** Slifer the Sky Dragon has two Breath Weapons, one for each mouth. His first mouth fires the yellow Thunder Force (the Japanese name is ''Chō den dō wa - Thunder Force/Super Electrical Conduction Wave - Thunder Force''), aiming for attacking. His second mouth fires the blue Lightning Blast (the Japanese name is ''Shōraidan/Summon Thunder Bullet''), aiming for reducing the ATK or DEF of the opponent's new summoned monster by 2000 points.
* Piyoko has her Upchuck Bazooka attack to counter ''DiGiCharat'''s Mekara Beam (which ''she'' shoots from her eyes).
* Bellcross from ''HeroicAge'' does this several times, being sure to clean up the local space of annoying bug-aliens by using their own life force and energy to power it.
* Some Zoanoids in ''{{Guyver}}'' have this; Derzerb of the [[FiveManBand Hyper-Zoanoid Five]] could breathe napalm, and the Zoalord De Galenos fires energy blasts from his mouth.
* In the final episodes of ''Anime/FullmetalAlchemist'', a cyborg produces a number of guns from surprising places, including a tiny ''ball turret'' in his mouth.
* From ''{{Potemayo}}'', the things on the sides of Guchuko's head shoot a charring variety of beam.
* The God Warriors in ''Manga/NausicaaOfTheValleyOfTheWind''.
* Friedrich of ''[[MagicalGirlLyricalNanohaStrikerS Magical Girl Lyrical Nanoha]]'', being a [[OurDragonsAreDifferent dragon]], has his Blast Flare and Blast Rain attacks.
* If mecha count, you can include pretty much any [[{{Zoids}} Zoid]] with a Charged Particle Beam. 9 times out of 10, the cannon fires from the mouth (with the exception of the Death Stinger).
* [[MentorMascot Kero]] of ''Manga/CardcaptorSakura'' gained the ability to breathe fire once Sakura managed to capture [[PlayingWithFire The Firey]].
* ''Manga/MahouSenseiNegima'' has several dragons (including one that breathes RazorWind), in addition to a number of robots with mouth-mounted [[ClothingDamage stripper rays]].
* The Tailed Beasts in ''Anime/{{Naruto}}'' are all capable of firing highly destructive balls of pure chakra from their mouths. Several of them also have other breath attacks, such as Shukaku's balls of concentrated air and the Two-Tailed Cat's fireballs.
** Unlike the typical example of this trope, Breath Weapons are more commonly used by the ''heroes''; Shizune can breath out poison mist, the Fifth Mizukage can spit ''acid mist and lava'', the Sarutobi clan can all breath fire, Jiraiya and the toads can spit oil, etc. Which isn't to say that the antagonists don't get in on the action; for example, Danzo can fire wind bullets, while the Uchiha antagonists are all fire-breathers as well.
** Parodied when Naruto tries to do this while (consciously) using his Tailed Beast's power. [[spoiler:The 8-Tails]] describes it as sort of like vomiting, prompting Naruto to ''actually try and make himself vomit'', which [[VomitIndiscretionShot works about as well as you'd think]] (he wasn't in the right form anyway).
* Many ''Franchise/{{Digimon}}'' have breath weapons, at least until the higher evolutions when they usually grow actual cannons.
* ''Manga/OnePiece'''s Bartholomew Kuma had a mouth beam built into him to add on to his other powers. The Pacifista modeled after him likewise have a mouth beam built in them.
** [[HollywoodCyborg Franky]] on the other hand is equipped with both a flamethrower and built in nailgun.
** A giant bird in the Skypiea arc had a flame-dial in its beak and both Buggy and Kidd had firebreathers in their crews.
** Before any of these examples was Mr. 5. Using the Bomb-Bomb Fruit, he's able to make any part of his body explode, including his breath, which he loads into a gun.
** In the first movie, the main antagonist ate the Goe Goe no Mi, which gave him this ability.
* ''[[DoctorSlump Dr. Slump's]]'' [[ActionGirl Arale]] and her deadly [[RuleOfFunny N'cha! Beam]].
* ''KeroroGunsou'' has Tamama's signature move, the "Tamama Impact".
* A common attack of Let and Julia's in ''RaveMaster''. There's also a Blue Gaurdian member with a Dark Bring that grants him one.
* Natsu and all of the Dragon Slayers from ''Manga/FairyTail'' sport this ability, called the "[Element] Dragon's Roar", which ranges from shooting [[PlayingWithFire fire]], ''[[ExtraOreDinary metal]]'', [[ShockAndAwe lightning]], [[BlowYouAway wind]], [[PoisonousPerson poison]], [[LightEmUp light]], and [[CastinAShadow shadow]]. Of course, dragons do this, too.
* ''IchibanUshiroNoDaimaou'' has Peterhausen, a dragon who can shoot ''[[ThisIsADrill drills from out of his mouth.]]''
* Flame Convoy in ''[[TransformersCybertron Transformers: Galaxy Force]]'' has this as part of his Force Chip Ignition power.
* Zatch/Gash, in his namesake series ''ZatchBell'' / ''Konjiki no Gash!!'' gets a series of spells that short bursts of lightning out of his mouth, and in one of the more powerful spells, the lightning forms into a dragon. Not to mention he's also a demon, although he looks exactly like a human child hold the lines down his cheeks and the horn hidden in his hair.
* Kumo, Kiri, and most probably all other Mystarians in ''FinalFantasyUnlimited.''
* Most dragons in ''{{Slayers}}'' just use old-fashioned fire breath, but gold dragons have '''laser''' breath.
* The RahXephon has this as a WaveMotionGun. And now everyone after me: '''[[MakeMeWannaShout RRAAAAAAAAAAAAAAAAAAAHH!!!]]'''
* Chikuma Koshirou from ''Manga/{{Basilisk}}'' can create [[WeaponsThatSuck little vacuums that rip his enemies to shreds]] merely by breathing.
* ''Manga/RurouniKenshin'' has a character who tries to pass himself off as this, though he is revealed to have a bag of gasoline in his stomach that allows him to use flame as a weapon.
* Free's Magic Eye Cannon from Soul Eater ([[NonIndicativeName despite the name]]) has him firing a huge laser from his mouth.
