-> ''"All I know is, this Lo Pan character comes out of thin air in the middle of a goddamn alley while his buddies are flying around on wires cutting everybody to shreds, and he just stands there waiting for me to drive my truck straight through him with'' '''LIGHT''' ''coming out of his mouth?''"
-->-- '''Jack Burton''', ''Film/BigTroubleInLittleChina''

Whenever a character becomes [[SuperWeight powerful enough]], they will demonstrate PowerGlows with a BattleAura that can range anywhere from nightlight to supernova. Other characters aren't quite so flashy, instead of turning into a human candle, they become more akin to a human ''lampshade'' as light pours out of every orifice (well, the ones on the face anyway... minus the ears and nostrils... okay, fine, just the eyes and mouth), as if they had a (potentially literal) inner fire. This may even be bright enough to be seen through their skin.

[[GlowingEyesOfDoom Their eyes will glow]], their mouth will light up [[SuckingInLines as if they were about]] to [[BreathWeapon breathe fire]]... or [[AnIcePerson ice!]] Characters with a [[TitleDrop Throat Light]] can have it be related to just about any [[ElementalPowers elemental power]], or due to being a machine, ghost, or some other strangeness. As with most PsychoactivePowers, the lights will blaze strongly when angry, low when sad, and [[EyeLightsOut flicker when near death.]] Sometimes, their mouth can fire up some FrickinLaserBeam or even a WaveMotionGun.

Another use of this trope is not as fun for the glowing person: The light coming out of your body might indicate that you are about to blow up or burn internally from an accumulation of energy.

This can be really intimidating since it tends to be scalding hot/cold.

Compare PreExplosionGlow. Contrast with EpilepticFlashingLights and GhostlyGape. If taken up to eleven, may become an EnergyBeing.


[[folder:Anime & Manga]]
* ''Manga/{{Bleach}}''. During "The New Captain Shūsuke Amagai" anime arc, several people have this while wielding Bakkōtō blades, including the assassin Hanza, [[spoiler:Captain Amagai's father and Captain Amagai himself]].
* In ''Anime/RebuildOfEvangelion'', Shinji and Unit-01's awakened upgrade against Zeruel comes with this.

* ''Manga/{{Naruto}}'': The Tailed Beast V2 forms have bright-white glowing mouths, GlowingEyesOfDoom included.
* ''Mister Ajikko'', a shonen anime about cooking, commonly abuses this effect to describe ''incredibly good food''. With no hint of parodic intent in sight, to boot.
* ''Anime/PokemonJirachiWishmaker'': [[spoiler:The Fake Groudon]] has this going for its eyes and mouth. Ironically, it never actually uses [[spoiler:[[BreathWeapon fire breath]]- [[Main/CombatTentacles not that it needs to]]]].

[[folder:Card Games]]
* The Visionary from ''TabletopGame/SentinelsOfTheMultiverse'' has at least a few cards depicting this. "Precognition" shows her emitting a glowing smoke from her eyes and mouth while the background shows a BadFuture, and Mind Spike depicts her blasting one of the villains with pure psychic energy, some of which leaks out the villain's face.

[[folder:Comic Books]]
* In ''ComicBook/{{Supergirl}}'' stories:
** ''ComicBook/{{Bizarrogirl}}'': Orange light and heat pour out of Bizarrogirl's throat when she is about to expel fire. In addition, her eyes glow red.
** In ''ComicBook/SupergirlCosmicAdventuresInThe8thGrade'', white light pours out of the eyes and mouths of the imps from the Fifth Dimension when they shed their human disguises.
* Finnegan from ''ComicBook/{{Witchblade}}'' (pictured above) when he's infused with the ElementalPowers of [[AnIcePerson Ice]]... which somehow also causes blue VolcanicVeins thanks to {{Power Crystal}}s.
* In ''Webcomic/TheOrderOfTheStick'' prequel book ''Recap/StartOfDarkness'', Redcloak has light pouring from his eyes, throat and holy symbol the very first time he puts on the [[ArtifactOfDoom Crimson Mantle]].
* Shinomura from the ''Film/{{Godzilla 2014}}'' tie-in comic ''Godzilla Awakening'' has a blue glow in its mouth.
* This is sometimes displayed by ComicBook/{{Etrigan}}, which makes sense since he can [[BreathWeapon breathe fire]]. In the 1984 miniseries, his eyes and mouth glow and constantly trail steam, and this happens to Jason Blood during the first stage of their transformation sequence.

[[folder: Fan Works]]
* In ''Fanfic/TheKeysStandAlone: The Soft World'', when the priest of Meddar channels his god, light erupts from every orifice, including his mouth, when the god speaks.

[[folder:Films -- Animation]]
* The gargoyle that offs Frollo at the end of ''Disney/TheHunchbackOfNotreDame''.
* Toothless gets one in ''WesternAnimation/HowToTrainYourDragon2'' after [[TookALevelInBadass taking a major level in Badass]].

* The creepy alien angel guys from ''Film/{{Knowing}}'', whose creepiness is upped by their only apparent communication being opening their mouths and emitting a light and a wail.
* In ''Film/TheLordOfTheRings'' films, the Balrog has this. It is also glowing from various cracks in its skin, the implication being that it is simply a giant flame in demonic form cloaked by shadow.

* ''Film/TheMatrixRevolutions''. This happens briefly to Neo at the end as the machines channel their power through him to destroy the Agents Smith, as well as to the Agent Smith that possessed the Oracle.

* This happens to Extremis soldiers in ''Film/IronMan3'' before they [[SuperpowerMeltdown blow up.]]
* In ''Film/PacificRim'', most {{Kaiju}} have a bioluminescent version of this. Their power lies elsewhere in comparison to most examples here, however.

* ''Literature/TheWheelOfTime'' has Ba'alzamon, whose mouth ([[GlowingEyesOfDoom and eyes]]) looks like endless caverns of flame when seen directly. This is a result of his overuse of [[BlackMagic the True Power]] and according to WordOfGod [[spoiler: as sign that it has consumed him so thoroughly that he'd die if he hadn't been granted immortality by [[GodOfEvil the Dark One]]]].
* In the ''Literature/SecondApocalypse'' books, the throats of sorcerers glow with light when they recite their magical cants.
* In ''[[Literature/JediAcademyTrilogy I, Jedi]]'', when Corran opens himself fully to TheForce for the first time, he finds it amazing, incredible, and says that he was completely filled with its power, which spilled and flowed from his eyes and mouth.
* In the ''Literature/OldKingdom'' books by Creator/GarthNix, Free Magic sorcerers flame from their mouths, eyes, fingernails, etc. as they cast, and get that way more and more, the more Free Magic they use, until they wind up as masses of flaming Free Magic. They appear to be fine with that.
* In ''Literature/MemorySorrowAndThorn'', the [[BigBad Storm King]] [[DemonicPossession possesses]] a victim at the climax in an attempt to [[SealedEvilInACan return to life]]. One of the symptoms of said possession is a deep reddish light coming out of the victim's mouth.
* Creator/CLMoore's story "Daemon" has this passage:
-->''I saw the flaming thing descend upon the captain like a falling star. Through his defending arms it swept, and through his flesh and his bones and into the hollows where the soul dwells.\\
He stood for an instant transfixed, motionless, glowing with that bath of crimson light. Then I saw the crimson begin to shine through him, so that the shadows of his bones stood out upon the skin. And then fire shot up, wreathing from his eyes and mouth and nostrils. He was a lantern of flesh for that fire of the burning spirit. But he was a lantern that is consumed by the flame it carries...''

[[folder:Live-Action TV]]
* A Goa'uld torture device in ''Series/StargateSG1'' causes this effect on the victim.
* Jim Staal had a recurring character on... some SketchComedy show, possibly ''Big City Comedy'', where he was the AnthropomorphicPersonification of your refrigerator (and EVIL!), who had a light in his mouth whenever he spoke.
* ''Series/DoctorWho'': The Doctor does this when he regenerates (transforming from one actor to another).

* [[http://www.youtube.com/watch?v=k9mSbqpSQak&ob=av2e "Kingdom"]] by Dave Gahan.

* [[http://www.youtube.com/watch?v=aU1wLryjuEw "Ich tu dir weh"]] by Music/{{Rammstein}} features frontman Till Lindemann using this trope with full force. They did this by piercing his cheek and inserting an LED light. Throughout the video, the wire coming out of his cheek is visible.
** He also wears the light while playing live.
* Music/LaurieAnderson, on the cover of her "United States Live" box set live album.

[[folder:Tabletop Games]]
* A common look for daemons in ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'', and the part-daemonic Dark Eldar Mandrakes in the latter (those with mouths anyway - Mandrakes tend to have featureless smooth faces that manifest either glowing eyes or just this kind of mouth, but not both. Though their infernal inner glow also shines out from slashes and carved runes in their flesh - which is jet black to emphasise the contrast).
* Happens in ''TabletopGame/{{Werewolf the Forsaken}}'', among the adherents of the Temple of Apollo. When on their Sacred Hunt, if the target has trespassed in one of their holy places and once the adherent uses enough abilities towards their prey, Apollo's power pours through the werewolf. Light spills from their mouth [[GlowingEyesofDoom and eyes]], granting them a number extra advantages and lighting up the area.

[[folder:Video Games]]
* In ''VideoGame/RecettearAnItemShopsTale'', this happens to [[spoiler: [[RobotGirl Arma]] when she's being hacked into and taken over remotely or displaying a warning.]]
* In ''VideoGame/DeadSpace2'', Isaac's recurring hallucination of Nicole has bright white light pouring out of her eyes and mouth.
* In ''VideoGame/PanzerDragoon Zwei'', Khourieats, a lizard-like animal used for riding and carrying, are killed by imperial decree if they develop one of these. Our hero Lundi decides to hide his because its forelegs mutated into ''wings'' as well (and that's just too cool to simply kill off). As it turns out, the light is a manifestation of their ''[[BreathWeapon Homing Laser Breath]]'', which TheEmpire didn't want getting out.
* In a variation, this happens in ''VideoGame/DeusExHumanRevolution'' to the FinalBoss when they overload and burn up from the inside.
* In ''VideoGame/StarcraftIIHeartOfTheSwarm'', Kerrigan finally disposes of [[spoiler: Arcturus Mengsk]] in such a manner. She channels a portion of her immense [[PsychicPowers psionic energies]] into him; far more than his human body is capable of holding. First, his eyes glow, then this happens, and then [[StuffBlowingUp he turns into a giant explosion]] that takes out the wall he's standing next to.
* The Boys of Silence in ''VideoGame/BioshockInfinite'' do this. They were huge brass helmets with no eyes and a gaping mouth that spews white light, to act as living security cameras in Comstock House. The light changes color if one sees you, and if it goes red, they emit an ear-piercing scream to alert the nearby lunatics.
* Helios in ''VideoGame/GodOfWar3'', whose severed head Kratos can use as a lantern, among other things.

[[folder:Web Comics]]
* Deliberately invoked by Big Ears in ''Webcomic/{{Goblins}}'' to scare off a crowd of human civilians, by putting the Axe of Prissan through his head and aligning the glowing yellow orb on top of the magic weapon with his throat. [[http://www.goblinscomic.com/05152008/ Behold.]]
* ''Webcomic/GirlGenius'': The "Fun-Sized Mobile Agony and Death Dispensors" (a.k.a. Devil Dogs) of Castle Heterodyne [[http://www.girlgeniusonline.com/comic.php?date=20080905 have this going]]. Not so much of a PowerGlows example, though, since they're clanks.
* After separating from [[spoiler:Flint]] the [[SurrealSymbolicHeads Box Head Boy]] in ''Webcomic/TheDreamwalkerChronicles'' combines a glowing disappearing mouth with [[GlowingEyes glowing eye holes]] when eating dreams.

[[folder:Web Original]]
* The ''WebVideo/JoueurDuGrenier'' special about [[http://www.joueurdugrenier.fr/hors-serie-dessins-animes-pour-garcons/ cartoons for boys]] ends up with a review of the ''Mister Ajikko'' anime, mentioned above, and comments about the exaggerated effects. Then [=JdG=] says "Imagine if the slightest thing you'd eat would make you--" while eating a bit of chocolate. Throat Light ensues, and then ''the Earth explodes''.

[[folder:Western Animation]]
* ''WesternAnimation/AvatarTheLastAirbender''
** Aang while in the Avatar state.
** As well as Lord Ozai in the final episode, while Aang [[spoiler:removes his firebending powers with energybending.]] Here, said Throat Lights are reaching PillarOfLight level.
* Puck, when he casts a spell, in ''WesternAnimation/{{Gargoyles}}''.
* Raven from ''WesternAnimation/TeenTitans'' does this in the episodes "Spellbound" and "The End" parts 1 and 3.

[[folder:Real Life]]

* Till Lindemann of Rammstein now sports a lit mouth as of the video for "Ich tu dir weh". It's removable, but he got a cheek piercing specifically for the purpose of wiring it.
* It is possible to get glow-in-the-dark braces.
