* A staple feature of the Japanese ''{{Kaiju}}'' genre.
** ''Franchise/{{Godzilla}}'' breathes concentrated streams of radiation. This appears to be a form of superheated vapor in the Showa era films, but becomes a pure energy beam in the 90s and beyond.
** Omitted in ''Film/{{Godzilla 1998}}'' (where he technically has a "power breath" that simply makes things catch on fire rather than producing fire itself).
** Godzilla has this power in ''Film/{{Godzilla 2014}}'', true to the original incarnation of him. Unlike the laser appearance from Toho's Heisei and Millennium eras, this incarnation's atomic breath is similar to the superheated vapour appearance from the Showa era. [[spoiler:He uses it as the ''coup de grāce'' against the female Muto three times, but it's only when he ''force-feeds'' it to her that it has any real effect.]]
** Ghidorah fires lightning bolts from its three mouths; these are sometimes called "gravity beams", and in ''Film/GodzillaFinalWars'' they actually have an anti-gravity effect.
** [[Film/GodzillaVsDestoroyah Destoroyah]] fires "micro-oxygen" rays that disintegrate matter.
** Franchise/{{Gamera}} breathes fire - a continuous stream in the original series, and exploding plasma balls in the modern films directed by Shusuke Kaneko. The sonic rays fired by frequent nemesis [[Film/GameraVsGyaos Gyaos]] straddle the line between Breath Weapon and MakeMeWannaShout.
** Really, this trope is so pervasive in the daikaiju genre that there is a great number of examples not listed here; attempting to include every one would likely prove fruitless.
* In keeping with its roots in the above genre, ''Film/PacificRim'' includes one Category 4 kaiju that spews blue corrosive slime from its mouth.
* Another ''Batman'' example: The Red Triangle Circus Gang in ''Film/BatmanReturns'' has a performer dressed as a devil who contributes to the atmosphere of street terrorism by "blowing fire" on a display of jumbo stuffed animals in a toy store. Batman dispatches him by turning the Batmobile around so that the car's exhaust pipe is facing him and shooting out a jet of flame, [[HoistByHisOwnPetard setting the performer on fire]].
* ''Film/PiratesOfTheCaribbeanAtWorldsEnd'' plays this one for laughs, as captain Jack Sparrow possesses bad breath of such potency as to be able to make people swoon.
** To put how bad his breath is in perspective, when face to...mouth with [[spoiler: the Krakken, whose breath is said to be the foulest thing on earth]] he barely even reacts to it.
* Imhotep belched out a huge swarm of flies in ''Film/{{The Mummy|1999}}''.
* ''Film/BlazingSaddles'' - during the big fight scene, the grizzled drunk prospector grabs a bad guy and exhales in his face, knocking him out.
* David Lo Pan from ''Film/BigTroubleInLittleChina'' fires a blinding blast of light from his mouth. The effects are only temporary, which is apparently common knowledge to residents of Little China.
* In ''Film/AfterEarth'' the Ursa can shoot stuff from their mouths which have an acid-like effect on enemy targets.
* Not quite breath, but Angel from ''Film/XMenFirstClass'' can spit {{Fireballs}}.
