->''"Whatever it is... it's got glowing evil eyes of evil!"''
-->-- '''Fidget''', ''VideoGame/DustAnElysianTail''

Whether a permanent indication of malevolence, the emergence of the SuperpoweredEvilSide, or perhaps the result of a BerserkButton or RantInducingSlight, these eyes are ''clearly'' not a good sign. However, they aren't necessarily the province of villains -- particularly powerful heroes often manifest this trope when it's [[LetsGetDangerous time for the gloves to come off.]] Unlike RedEyesTakeWarning, these ''always'' mean immediate trouble and thus are near the top of the hierarchy of UhOhEyes.

''Very'' good for giving the DeathGlare. A SlasherSmile or other happily murderous expression doesn't hurt, either.

You can usually tell the trouble is over when the [[EyeLightsOut eye lights go out]]. [[GlowingEyelightsOfUndeath Unless they come back]].

Compare TheDarknessGazesBack.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* Yato in ''Manga/{{Noragami}}'' gains those in the final episode of the anime.
* Lelouch in ''Anime/CodeGeass'' (and everyone else with Geass) does this every time the Geass is used.
* For TheHero of ''Manga/FistOfTheNorthStar'', Kenshiro has a '''seriously''' evil-looking pair of ''[[RedEyesTakeWarning red]]'' Glowing Eyes Of Doom whenever you [[TooDumbToLive get]] [[ThisIsUnforgivable him]] [[WhatAnIdiot seriously]] [[YouAreAlreadyDead angry.]]
** The original anime also gives him a set of white glowing eyes when his BattleAura kicks in and his shirt comes off.
* The title character of ''Manga/HayateTheCombatButler'' resorts to this after being hit by a car. The occupants instantly surrender. It gets used a little more in the manga than the anime, but mostly by Hayate and it's pretty much always a CrowningMomentOfAwesome [[spoiler:such as coming back from a CurbStompBattle against Machina because the latter tried to take the Stone of Bonds]] or CrowningMomentOfFunny [[spoiler: such as when Hayate actually does something nice for Kotetsu and promptly takes him out with a vicious elbow to the chest when he tries to propose again]].
* Quant and Yuri from ''Webcomic/TowerOfGod'' sometimes sport red glowing eyes in the dark. They stem from a technique that enables them to see in the dark. Which coincidentally is when they are mist willing to grievously injure people.
* {{Manga/Naruto}}'s eyes start glowing red when he [[SuperpoweredEvilSide lets his emotions get the better of him]]. However, upon reaching the [[FourIsDeath 4-tailed state]], his eyes turn completely white, and his eyes and [[ThroatLight mouth]] glow like a Jack-O-Lantern.
* One of the shinigami in ''Manga/DeathNote'' gains these eyes at one point while going for some dramatic kills. Light tends to do this, as well, to reflect his Kira persona. Mikami and Misa, too.
* Even HumongousMecha do this at times:
** ''Anime/MazingerZ'': When the eyes of the titular HumongousMecha glowed, you knew you had to run for cover. Often it happened when [[TheHero Kouji]] [[HotBlooded was really, REALLY fired up]] or even panicked and somehow his state of mood affected his mecha (which suggests Mazinger was sentient, a point plot later versions have explored). A memorable example happened in ''ShinMazingerZero''. Mazinger was chained by a {{Robeast}} and unable to get free as another Mechanical Beast was disintegrating [[LoveInterests Sayaka's]] HumongousMecha. Then Kouji got REAL MAD, and Mazinger's eyes glowed right before he shattered the chains binding it and delivered a CurbStompBattle to both {{Robeast}}s.
** Zeon mecha from ''Anime/MobileSuitGundam'' in particular are notable for a [[CyberCyclops single mono-eye]] that seems to have no purpose other than to swivel towards the camera and glow menacingly.
** ''[[Anime/MobileSuitGundamWing Gundam Wing]]'' took it a step further, with the image of a Gundam or other mobile suit appearing in front of an enemy bridge, eyes glowing, before the bridge explodes (usually due to a beam saber strike) becoming so visually impressive that every series since has copied it.
** Also in ''Gundam Wing'', characters unable to control the [[ForgottenSuperweapon ZERO System]] enter an UnstoppableRage, marked by glowing golden eyes.
** In ''[[Anime/MobileSuitGundam00 Gundam00]]'', when the innovators use [[{{Telepathy}} quantum brainwaves]] to send messages to each other. Or, alternatively, when "fucking Ribbons" uses said quantum brainwaves to hijack their minds.
** Also, the Evas' eyes in ''Anime/NeonGenesisEvangelion'' glow white when they enter 'Berserk Mode', which generally means their opponent is [[DoomyDoomsOfDoom doomed]]. ''Anime/RebuildOfEvangelion'' takes this a step further at the end of the second movie when Shinji, his EVA out of power and the 14th angel beating the hell out of him, finally snaps. We are treated to an absolutely terrifying scene of his eyes glowing '''''[[RedEyesTakeWarning Blood Red]]''''' before, in an explosion of pure rage, he ''re-activates EVA-01 through sheer force of will'' and begins one of the most ''awesome'' beat-downs in the franchise's history. If there is any possibility for his Eva to look even scarier than it normally is while berserk, this is it.
*** When Mari switched Unit-02 into Beast mode, her eyes turned into an almost white hue of green. [[spoiler:Asuka later gets glowing blue eyes when she puts Unit-02 into Beast mode, even her left eye (under the eye-patch) glows.]]
*** In conclusion, it seems that taking the Entry Plug to unsafe depths causes this trope as a side effect. It may have something to do with all those warnings that a pilot who does this risks losing their humanity.
** ''Anime/TengenToppaGurrenLagann'''s title mech, the Gurren Lagann, does it as well, usually combining it with [[IncendiaryExponent something lighting on fire]] as the heroes become even more [[HeroicResolve resolved]]. The one time this is used against them is phenomenally awesome, as the main bad guy of the first part of the series [[spoiler:gets out of his Ganmen, walks over it, on foot, with his head on fire, with glowing eyes of doom raging, and PUNCHES THE SHIT OUT OF LAGANN BARE-HANDED. Lord Genome is a force to be feared.]]
* Most of the cast of ''VisualNovel/HigurashiNoNakuKoroNi'' do this both humorously and seriously. Not being able to tell which is which amps up the creep factor.
* The title character of ''Manga/RurouniKenshin'' does this when he goes into [[SuperpoweredEvilSide Battousai mode]].
** Makoto Shishio from ''Manga/RurouniKenshin'', after being shot through a wall, looks menacingly at the main characters with Glowing Eyes Of Doom.
* ''Manga/GirlsBravo'': Humorously done by Lisa, Kosame, Fukuyama when they're pursuing Yukinari, Kirie, and Koyomi respectively, as well as Kirie at one point.
* ''Manga/NagasareteAirantou'': Humorously, as the women close in on their "prey" like zombies.
* ''Manga/InuYasha'': A sign of {{Youkai}} malevolence and/or power-activation. In particular, it happens whenever [[TheHero Inuyasha's]] SuperpoweredEvilSide starts taking over or when [[AloofBigBrother Sesshoumaru]] begins to transform into his [[CanisMajor true form]]. Neither event is a good thing.
* ''Manga/FullmetalAlchemist''
** Although it still isn't common, a lot of characters exhibit this trait -- including both Elrics, Izumi, Winry, most (if not all) homunculi and some others.
** On a more humorous note, Ed's eyes occasionally do it too when someone insinuates that [[BerserkButton he's short]].
** Roy did it [[GreenEyedMonster (hilariously)]] when Barry the Chopper was hitting on [[SubordinateExcuse Hawkeye]]. [[spoiler:He pulls a much less hilarious and much more terrifying version of this when completely curbstomping Envy, especially when the latter tried to kill Riza.]]
** In ''Brotherhood'', Kimblee once does this while giving Ed a BreakingSpeech [[spoiler:and then proceeds to blow him up with a hidden Philosopher's stone.]]
** Averted with [[GentleGiant Al's]] eyes which appear as small pools of light, that disappear when he is unconscious.
* ''Manga/AzumangaDaioh'''s Yukari-sensei, after Tomo accidentally hits her in the face with a tray.
* ''Manga/DragonBall''
** Happens often in the first half of ''Dragon Ball Z'', most often pertaining to Gohan, who would occasionally fall into a superpowered [[UnstoppableRage psychotic rage]], during which his eyes would lack pupils and become more pronounced, at least during the loss of control.
** Goku also does this during his first Super Saiyan transformation.
** Happens later in ''Anime/DragonBallGT'' with any characters possessed by Baby.
** When Future Trunks powers up to Ultra Super Saiyan against Perfect Cell, his eyes briefly flash and glow white, similar to Broly in his Legendary Super Saiyan form.
* Kazuma's eyes in ''LightNovel/KazeNoStigma'' glow blue when he taps into his full powers, and ''[[RedEyesTakeWarning red]]'' when he's reverted to his SuperpoweredEvilSide.
* Vash The Stampede of ''Manga/TriGun'' is usually an easy-going [[ObfuscatingStupidity harmless goofball]], but when you force his hand, he will put on the ScaryShinyGlasses and [[LetsGetDangerous start fighting you for real]], though you won't be in any danger of actually dying. However, when you do something bad enough to actually make him angry, he will jump straight into this trope and proceed to ''[[CurbStompBattle utterly trounce you]]''. When this happened in the episode "Diablo", [[UnstoppableRage it was the closest he ever got]] to [[BewareTheNiceOnes deliberately killing a person]]. [[spoiler: Until Legato.]]
* Yusuke from ''Manga/YuYuHakusho'' gets these several times; once during his fight with Suzaku when [[spoiler: he's about to use up all his life energy to win]], once while glaring at Younger Toguro from the stands of the Dark Tournament, and occasionally thereafter while powering up or in the middle of a particularly intense fight - especially when, at the end of the Chapter Black saga, he [[spoiler: is taken over by his ancestor, Raizen, shortly after being killed and returning to life as a demon. Where before Yusuke's Glowing Eyes Of Doom have always been blue, these are red, possibly to signify either his new demonic nature or the foreign presence in his body.]]
* Also Sensui when he releases his sacred energy does it in an eerie and gradual way, followed by a powerful laugh that literally stresses the planet as he powers up.
* In ''Manga/BlueDrop'', Hagino Senkouji's eyes glow a brilliant blue right before she [[LoveAtFirstPunch tries to strangle another character]]. It also happens when she summons her space ship.
* In ''{{VisualNovel/Clannad}}'', Kyou's eyes [[RedEyesTakeWarning glow red]] as she strangles Tomoya and Sunohara after they pull a prank on her sister.
** In the game, though, anytime she's mad (which is quite often), Kyou will pull this off.
* ''Anime/MagicalGirlLyricalNanohaStrikerS''
** Subaru invokes this trope when [[spoiler:the Numbers abduct her sister and she activates her Combat Cyborg nature in response]] before [[UnstoppableRage going completely berserk on them]].
** Fate did this in the first season of the show during her second appearance, appearing as a black silhouette with Alucard-style glowing yellow circles.
* Ryoko in ''Anime/TenchiMuyo'' does this sometimes. It's not too big a deal if they're glowing yellow -- that just means she's a bit narked -- but when they glow red, she's ready to kick booty at the planetary level. If they turn green, well, let's just say she's not being herself.
* Parodied in ''[[Anime/PrettySammy Magical Project S]]'' when Ginji Kawai (Sasami's father) gets a little over-enthusiastic while flying Washu's rocket.
* When informed of the fact that she could turn {{Manga/Genshiken}} into a cosplay research club as president, Ohno gets Glowing Eyes Of Doom. In fact she gets Glowing Eyes Of Doom whenever she gets sufficiently obsessed about something, mainly cosplay-related.
* The Count in ''{{Anime/Gankutsuou}}'' does this a few times.
* Two characters from ''Anime/{{Mai HiME}}'' get these -- Mikoto (gold) and Nao ({{red|EyesTakeWarning}}). Also Shizuru, when she arrives to help Natsuki against Nao, knocking her and her Child off a cliff (although she still appears to be sane at the time).
* When Chika finds a photograph of Tina and Kaoru In ''Manga/AiYoriAoshi'', Tina gets perfectly round Glowing Eyes Of Doom combined with HiddenEyes-style shadowing. After the cutaway for various spooky imagery, Tina's bright and cheery, while ''Chika's'' [[BlankWhiteEyes petrified]].
* The most powerful fighters in ''Manga/IkkiTousen'' get these when they summon their inner dragons.
* Ichika from ''Anime/UtaKata'' gets glowing eyes when she gets afflicted by her powers, leading one very spooky scene when she approaches Manatsu while she sleeps.
* Zelgadis in ''{{LightNovel/Slayers}}'' gets these when Rezo takes control over him when he needs to stall for time. A few scenes later and Rezo manages to summon Shabranigdo -- only to learn that Shabranigdo was actually sealed inside his own eyes. Naturally, this leads to more glowing eyes to signify that Shabranigdo is taking over Rezo's body.
* ''Manga/SoulEater''
** Medusa is fond of this.
** [[spoiler: Death the Kid]] also starts glowing toward the end of the anime.
** Might be the intended look of how Noah's eyes are occasionally drawn in the manga.
** Members of the Star Clan gain golden star pupils.
** [[TheHero Maka]] only has flat green eyes normally, without any pupils, but when she is angry, scared, or in a fight, her eyes glow yellowish-green and pupils appear. Interestingly, if she is shocked they glow red for a moment, but only in the anime.
* ''{{Manga/Bleach}}'' has a few examples.
** [[TheHero Ichigo's]] eye sockets were completely empty for one fight until one brief moment when and for a moment all that's visible through the smoke are his glowing SupernaturalGoldEyes.This becomes a major OhCrap moment for Ulquiorra due to Ichigo's unusual and uncontrollable SuperpoweredEvilSide upgrade. His eyes changed to RedEyesTakeWarning when the fight was re-animated for the fourth film.
** [[BaldOfAwesome Ikkaku's]] eyes glow when he activates bankai against Edorad. It does not end well for Edorad.
** Episode 217 of the anime when [[VillainousCrossdresser Cuulhorne]] has [[BloodKnight Yumichika]] at his mercy and unleashes his [[DespairEventHorizon final technique]]. Yumichika simply ''[[CrowningMomentOfAwesome thanks]]'' him for doing that as his eyes begin to glow with [[AlmightyJanitor hidden power]]. CurbStompBattle is the only description for what happens next.
** In Episode 303, several highly seated officers engage in a [[MarsAndVenusGenderContrast Men-versus-Women]] card [[ThisMeansWar competition]]. The final card to be competed over is a picture of [[EvenTheGirlsWantHer Yoruichi]]. The surviving competitors charge for the card only to stop at the build-up of power behind them. They find themselves staring down the [[ArmCannon barrel]] of Soi Fon's [[NukeEm bankai]] as her eyes glow wildly with her [[LawOfDisproportionateResponse determination]] to [[ThereIsNoKillLikeOverkill obtain Yoruichi's card]].
* Lime in ''Anime/SaberMarionetteJ'' has these when first activated, and again when Hanagata pisses her off.
* The eyes of Tohno Shiki and Ryougi Shiki from the ''{{Nasuverse}}'' glows bright blue; it is the result of their UhOhEyes of death. Ryougi's eyes only does this when she activates them but Tohno's eyes are always activated. They become more apparent when he takes off his glasses, though, a sign that he is in his "killing mode."
* [[BigBad Creed]] from ''Manga/BlackCat'' did this when his precious time with Train was constantly interrupted by others. And no, it wasn't played for humor.
* Rail Tracer in ''{{LightNovel/Baccano}}'' enjoys this trope almost as much as it enjoys dragging people under moving trains and grating their limbs and faces against the rails, which is a lot.
* ''Manga/BlackLagoon'' managed to pull this off in a late episode when Rock upset Balalaika - she stood over him at an angle at which light reflected off her glass eye, evoking the trope.
* The Shin Red Eyes in ''Manga/SamuraiDeeperKyo'' is the Glowing Eyes Of Doom upgrade of the Mibu clan's regular {{Red Eyes|TakeWarning}}.
* Used occasionally in ''Manga/OnePiece''. One notable ([[CrowningMomentOfFunny and hilarious]]) scene is [[http://www.youtube.com/watch?v=Zqgid-ob6Rc during the battle with Oz]].
* ''{{Manga/Hellsing}}''
** Both Alucard and Anderson invoke this trope whenever they stop screwing around and are about to curbstomp someone into the ground.
** Seras Victoria gets it later on when she becomes a true vampire and regenerates her eyes. The effect is enough to terrify a horde of Nazi vampires. They're right to be frightened, considering [[RoaringRampageOfRevenge what she does to them next.]]
* One of ''Manga/FushigiYuugi'''s later villains, Tenkou, makes his first appearance as just a pair of glowing white eyes amidst flames. And a [[EvilSoundsDeep creepy disembodied voice]].
* Himeno of ''{{Manga/Pretear}}'' occasionally gets these when she is angry.
* In the hilarious ''[[VideoGame/HarukanaruTokiNoNakaDe Harukanaru Toki no Naka de - Hachiyou Shou]]'' OAV episode "Omoi no Arika", [[SmallAnnoyingCreature Kotengu]] manages to induce these in, [[YoungerThanTheyLook of]] [[TheStoic all]] [[ArtificialHuman people]], '''[[{{Onmyodo}} Yasuaki]]'''.
* Takeda Shingen from ''VideoGame/SengokuBasara'' whenever an epic beatdown is in order. Young BloodKnight Date Masamune also does this whenever he's ''really'' enjoying a fight.
* In ''Manga/KenichiTheMightiestDisciple'' pretty much every single master in Ryozanpaku shows Glowing Eyes Of Doom periodically, and not even when fighting other masters, but rather during the {{training|FromHell}} [[ColdBloodedTorture sessions]] with their own disciple.
* In ''{{Manga/Berserk}}'', the houndlike "Beast" that sometimes appears in Guts's dreams and that represents his darker side post-Eclipse has two really evil-looking red glowing eyes, and when Guts is under its sway, his good eye will often glow red like the hound, best illustrated in the PS2 game which focuses on the Millennium Falcon arc.
* In ''Anime/DarkerThanBlack'', Contractors' eyes glow [[RedEyesTakeWarning red]] when they use their powers. [[GlamourFailure It's almost the only way of identifying them]].
* This happens in ''Manga/BokuNoFutatsuNoTsubasa'' [[http://www.mangafox.com/manga/boku_no_futatsu_no_tsubasa/v05/c037/19.html here]].
* In the ''Manga/ChronoCrusade'' anime, the [[OurDemonsAreDifferent demons]] tend to have Glowing Eyes Of Doom when they're unleashing their full powers. Chrono in particular seems to get these when he's being overcome with UnstoppableRage.
* ''{{Anime/Pokemon}}'': If Mewtwo does this and he's looking at you, kiss your ass goodbye. Same goes for Psyduck.
* Casshern's cyan eyes in ''Anime/CasshernSins'' glow during combat.
* PlayedForLaughs in ''Anime/FullMetalPanicFumoffu'' after Sagara [[TrainingFromHell trains]] the rugby team this is what happens to the peaceful rugby team from Kaname and Sagara school.
* In a recent ''{{Anime/Bakugan}}'' episode, Drago's eyes began to glow. And then the stadium exploded.
* Though he... she... [[AmbiguousGender it]] normally just has a pair of creepy {{red eyes|TakeWarning}} [[WeaselMascot Kyubey]] of ''Anime/PuellaMagiMadokaMagica'' pulls the glowing eyes of doom off [[http://geekrevolt.com/wp-content/uploads/2011/02/Kyubey-Creepy-Red-Eyes.jpg rather well]] after [[spoiler: getting shot by Homura and coming back]]
* While not particularly malevolent, the Bus Driver and school Chairman both have glowing, white eyes in ''Manga/RosarioToVampire''.
* Towards the end of the Tower of Heaven arc in ''Manga/FairyTail'', Natsu [[spoiler:eats some of the Etherion]] Initially his eyes glow ice blue, the same color as the Etherion; then he starts choking, and his eyes [[FireballEyeballs blaze up into flames]]. Much ass kickery ensues.
* Momoyo in ''VisualNovel/MajiDeWatashiNiKoiShinasai'', whenever she's about to get serious. It helps that [[RedEyesTakeWarning her eyes are red]].
* The eponymous Manga/{{Claymore}}s get this when they activate their Yoma powers.
* Vincent's eyes start to glow when he becomes Anime/ErgoProxy. This generally does not bode well, [[AmnesiacGod considering what he is]]. Similarly, the other Proxies also exhibit this trope when initiating aggressive action.
* When the [[TheBully Archdemon]] ravaged the kids eight years before the current ''Manga/DailyLivesOfHighSchoolBoys'' plot, [[spoiler:she]] has red, glowing eyes.
* [[WinterRoyalLady Ooyuki]] will do this when she gets mad. Making her angry is as difficult as it is a [[BewareTheNiceOnes bad idea]].
* ''Manga/RanmaOneHalf'': Ryoga's eyes go entirely pink-red and glow with similar-coloured energy to his attack & aura when he's channelling a particularly powerful (or Perfected) [[AngstNuke Shi Shi Hokodan.]]
* PlayedForLaughs in episode 4 of ''Manga/KotouraSan'', when the rest of the ESP Club did this to Haruka so that they could "catch" her.
* Used for dramatic effect in ''PandoraHearts'' Retrace LXI on Vincent's [[RedEyesTakeWarning red]] eye right when he [[spoiler:uses Demios to behead Duke Nightray]].
* If you see this in ''Anime/IlSolePenetraLeIllusioni'' it's guaranteed that that person is possessed by a daemonia.
* Patchouli gets these in ''Anime/MusouKakyouASummerDaysDream'' after [[BerserkButton getting hit in the face with one of her own books]] during an argument by Marisa and Aya. The next shot is Patchy busting out her [[PlayingWithFire Royal Flare]] spell card.
* In Act 1 of ''Anime/SailorMoonCrystal,'' the jewelry store customers under the thrall of the MonsterOfTheDay Morga's {{Hypno Trinket}}s have glowing {{Red|EyesTakeWarning}} MindControlEyes when she summons them as a BrainwashedAndCrazy army to attack Sailor Moon.
* Compared to most of the other entries on this page, the settings and characters in ''Manga/DetectiveConan'' are realistic. However, during one case set at a hotel's onsen, Conan inadvertently mortifies Ai several times while delivering the case's resolution. Ai not only gains this trope, but also ''a malevolent aura'' on top of that.

[[folder:Comic Books]]
* When Franchise/{{Superman}} wants to be intimidating, he likes to appear in shadow with [[http://media.filmschoolrejects.com/images/evil-superman.jpg his eyes glowing a fierce red]] as if ready to fire his [[EyeBeams heat vision]].
** ''ComicBook/ForTheManWhoHasEverything''
-->[[Awesome/{{Superman}} "Bu]][[http://goodcomics.comicbookresources.com/wp-content/uploads/2009/01/burn.jpg rn."]]
* Several ''Comicbook/{{X-Men}}'' characters do this.
** When a villain (or ComicBook/{{Wolverine}}) is ''really'' getting on ComicBook/{{Cyclops}}' nerves, a glow can be seen through/around his shades or visor. As his EyeBeams are [[PowerIncontinence always on]], this probably indicates that their blast is becoming far more intense.
** ComicBook/{{Storm}}'s eyes become solid white and glowing when she uses her powers. This carries into almost all adaptations.
** When SelfDemonstrating/{{Magneto}} gets angry, his eyes glow as well, independent of power usage.
** ComicBook/{{Gambit}}'s eyes have been known to give off red energy when he's intended to look particularly badass.
** Comicbook/{{Cable}} and his alternate-universe clone ComicBook/XMan both have glowing left eyes.
*** Only when [[Creator/RobLiefeld Liefeld]] manages to remember that the left eye is the glowing eye, since he seems to forget half the time.
*** Being related to Cyclops will do that. His other brother Kid Vulcan has them, and his alt-reality daughter Ruby does as well.
** Sometimes Nightcrawler is shown with Glowy-eyes when he's lurking in the shadows.
** Jean Grey and anyone else possessed by the Phoenix Force tends to have solid glowing gold eyes when they use the Phoenix powers.
*** Her daughter [[Characters/XMen80sMembers Rachel]] (who actually was the Phoenix host for far longer Jean, not that any writers remember that these days) has a glowing left eye (just like her half-brother Cable; see above), except that in addition to the glow it's surrounded by a glowing Phoenix emblem. Normally it's yellow, but a recent upgrade turned it blue.
** When Wolverine is introduced in the first ''ComicBook/UltimateXMen'' storyarc, he is seen perched up in a tree, hidden in the shadows. Except his eyes are glowing for some reason. Not "cat-eye reflected in the light" glowing either, more like "Superman about to unleash the heat vision." No explanation given.
** ComicBook/{{X-23}}'s eyes normally just [[RedEyesTakeWarning turn red]] when she's under the effects of the trigger scent, an indication that she's about to turn anyone who gets in her way into meat confetti. However in one arc of her solo series they actually started ''glowing''.
* In the ''VideoGame/StarFox'' comic from ''Magazine/NintendoPower'', Fox [=McCloud=] gets these on two occasions. One is right at the beginning, where Falco hits Fox's BerserkButton by suggesting raiding commercial freighters instead of the Imperial ships the team usually targeted in the beginning ("Feathers for brains! For the last time, we are '''NOT THIEVES!'''"). The other is right at the end when Fox goes into UnstoppableRage mode after learning the truth about what happened to his mother and father.
* Even {{Badass Normal}}s seem to get glowing eyes when they're lurking in shadows. The entire [[{{Franchise/Batman}} Bat-family]] for example seemed to have glow-in-the-dark lenses in their masks. {{Rule of Cool}} excuses this for the most part.
* Sistah Spooky from ''ComicBook/{{Empowered}}'' seems to get these under extreme emotional stress. [[spoiler: How extreme? Picture watching the love of your life die as you are literally seconds from saving her, then having your worst enemy (in your own mind) show up to gloat.]] If things get that bad, running is not even an option. [[spoiler:Said 'enemy' [[HeroicBSOD breaking down]] because she chose to save her over herself, is.]]
* Due to their connection with the Speed Force, [[Franchise/TheFlash Flashes]] and other speedsters sometimes get glowing eyes (or, as Bart likes to put it, "lightning eyes"). This is ''mostly'' involuntary, but it usually does happen at moments clearly meant to be significant, so it all works out.
* In ''ComicBook/MegaMan'', the end of issue 3 had the Robot Masters standing behind Dr. Wily with their eyes glowing.
* Comicbook/DoctorStrange sometimes gets these when spellcasting. Considering that he has a lot of dangerous spells which don't make his eyes glow, these are a good cue that he's ''really'' getting serious.
* Similary to the above example, Wiccan of ''ComicBook/YoungAvengers'' has these when using his spellcasting/reality warping abilities; but the most memorable example is when he put everyone in Central Park into a magical coma.
[[/folder]]

[[folder:Fan Works]]
* ''FanFic/DragonAgeTheCrownOfThorns''
** The dwarven noble protagonist, being a [[spoiler:[[MagicKnight Spirit Warrior]] of sorts]], suffers from this effect whenever he calls on the energies of the Fade. The glow is pure white and can extend to his whole body and even become something like a shroud of mist-like gossamer strands around him, depending on how much power he pumps out.
** Alim Surana has a true sight spell that makes his own eyes glow blue. His irises can shine crimson too, when he [[spoiler:uses blood magic]].
* In ''Fanfic/GameTheory'', [[spoiler:the automatons in the Garden of Time acquire these when the Jewel Seed tied into the defense system activates.]]
-->'''Vesta:''' [[LampshadeHanging ... I'm fairly sure evil glowiness is bad, mistress.]]
[[/folder]]

[[folder:Films -- Animation]]
* In ''WesternAnimation/TheIronGiant'', the title character's eyes glow red whenever he sees a weapon or is fired upon. If his rage becomes too great, he transforms into a nigh-unstoppable killing machine capable of taking out tanks (and possibly battleships).
* Chernobog, the Slavic dark god, in the "Night on Bald Mountain" segment of ''{{Disney/Fantasia}}''.
** ''WesternAnimation/AllegroNonTroppo'' also has a segment with such a villain; [[spoiler: an evil ape]].
** ''[[{{Disney/Fantasia}} Fantasia 2000]]'' features the Firebird, whose glowing eyes will give you [[EyeAwaken the fright]] [[ScareChord of your life]].
* ''WesternAnimation/TheSecretOfNIMH'' has a more benign application of this. Both Nicodemus and the Great Owl have glowing eyes to indicate that they are beings of mystical wisdom. And if you've never read [[Literature/MrsFrisbyAndTheRatsOfNIMH the book]], you'd be forgiven if you assumed that implied they were the same being (what with the glowing eyes and wispy grey fu manchus...)
* ''WesternAnimation/{{Megamind}}'': [[spoiler:Titan's]] eyes tend to glow when he get's ''really'' pissed off.
* ''Disney/{{Aladdin}}'': Jafar in his genie form has glowing yellow eyes, visible for about two seconds before he gets stuffed in a lamp.
* Zurg's eyes glow yellow in ''WesternAnimation/ToyStory2'' via lightpiping, explained in the {{Defictionalization}} of a ShowWithinAShow ''WesternAnimation/BuzzLightyearOfStarCommand'' as being related to heat vision.
* In ''WesternAnimation/TheHobbit'', Smaug the dragon's eyes actually shine like headlights, and illuminate what he is looking at.
* ''WesternAnimation/TheSnowQueen1995'' and its sequel end with the Snow Queen glaring at the camera to show she's still alive.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Franchise/StarWars''' Darth Vader's eyes glow a bright yellow when he goes off to kill all the Separatists. He covers his head with a hood, but you can tell that they glow in the shadow. Also, [[ArsonMurderAndJaywalking he is wearing eyeliner]]. [[EvilMakeover That's what happens when you go darkside]].
** Yellow eyes seems in fact to be a side effect of being a Sith. Darth Maul and the Emperor had them as well.
* Scott Howard, the titular werewolf from ''Film/TeenWolf'' uses this to hilarious effect along with a demonic voice to procure beer from a curmudgeonly old liquor store keeper without having to show ID.
* The {{creepy child}}ren from ''Film/VillageOfTheDamned'' have eyes that glow bright blue whenever they use their PsychicPowers.
* Louis Tully in ''Film/{{Ghostbusters}}'' got [[RedEyesTakeWarning glowy eyes]] after being possessed by Vinz Clortho, Keymaster of Gozer.
** Dr. Janosz Poha in ''Ghostbusters II'' gets them when possessed by Vigo the Carpathian; his actually shine out like headlights.
* The evil robot kids from ''Film/SpyKids'' have eyes which flash like this, accompanied by an electronic sound effect.
* Film/IronMan's eyes glow. But the trope is really invoked when, in the darkness, the Iron Monger suit's eyes switch on.
** People injected with the [[MyBloodRunsHot Extr]][[VolcanicVeins emis]] virus showcase their powers.
* The creature's mask's eyes in ''Franchise/{{Predator}}'' occasionally flash a yellow glow. This trick is brought back in ''[[Film/AlienVsPredator Aliens vs. Predator: Requiem]]'' , as well as in ''{{Film/Predators}}''.
* In the film adaptation of ''Literature/{{Dune}}'', the entire Freman race has glowing blue eyes, as a side-effect of their addiction to [[AppliedPhlebotinum the Spice.]] In the original novels, however, it was simply altered pigmentation, and they're eyes were just a weird kind of blue.
* If you're in ''Film/StarTrekVTheFinalFrontier'' and "God"'s eyes are glowing in response to your query to why he needs a starship, let's just say you're [[EyeBeams not going to get an honest answer]].
* Shows up in ''Film/TowerOfTerror'' as a trick by the ghosts.
* In ''Film/ScottPilgrimVsTheWorld'', Todd (a.k.a. ex-boyfriend #3) has eyes that glow whenever he uses his [[ItRunsOnNonsensoleum vegan superpowers]].
* Subverted in ''Film/AttackTheBlock''. We see an alien in the dark with what looks like glowing eyes--the glowing bits turn out to be teeth, and the aliens ''[[EyelessFace don't have eyes]].''
* In ''Film/{{Platoon}}'', Barnes' eyes glow in [[RedEyesTakeWarning red]] in Chris' hallucinogenic experience of the final battle.
* In ''Film/TheWorldsEnd'', the dopplegangers eyes and mouths glow with a blinding white light when they attack.
* The Mutos from ''Film/{{Godzilla 2014}}'' have red glowing slits for eyes, which lack any kind of pupils. They may be heat sensors or compound eyes.
* In ''Film/TheWolfman2010'', when Lawrence begins his first transformation, his father moves into the shadows, with his eyes creepily glowing in the darkness -- albeit only for a moment.
* ''Film/XMen'':
** Storm, when using her powers.
** The [[KillerRobot Sentinels]] from ''Film/XMenDaysOfFuturePast'' have glowing yellow eyes.
[[/folder]]

[[folder:Gamebooks]]
* An interesting variation occurs in the ''Literature/LoneWolf'' [[ChooseYourOwnAdventure gamebook]] ''The Kingdoms of Terror''. Lone Wolf is being attacked by a very fast monster with glowing eyes in a pitch-black castle. If you choose to fire an arrow at its eyes you actually get a bonus to your success roll since, because they're glowing, they're ''an easier target.''

[[folder:Literature]]
* Is an reccuring theme in ''Literature/{{Phenomena}}'', [[TheHeavy Tarkan]] has red glowing ones, [[ChaoticEvil Ezau]] has white glowing ones, and Azur has them, although he's not one of the antonagists.
* Drool Rockworm's permanently red-glowing eyes in ''Literature/TheChroniclesOfThomasCovenant'' are a typical example of this. On the other hand, Caerroil Wildwood with his silver-glowing eyes is not, being neutral to the good guys and doom for the bad guys.
** Lord Foul's eyes are definitely this, especially since they're the only things that are in focus.
* ''Literature/TheLordOfTheRings''
** The Nazgul are often depicted in art as having glowing red eyes. As they are normally invisible, this is their only visible feature.
** The [[KaleidoscopeEyes colour of the light]] shining from Gollum's eyes indicates which personality is in control.
* The vampires in ''Literature/BlackDaggerBrotherhood'' reverse this: their eyes glow like lighthouses when they see their mates. When they actually battle the bad guys, no glow.
* Franchise/StarWarsExpandedUniverse
** The yellow glowing eyes is common to all Dark Side practitioners in the ''Star Wars'' universe, and usually comes as a result of deep immersion in the Dark Side of the Force. Golden-yellow irises with a bloodshot rim, they are often referred to as "Sith Eyes" due to their obvious association with the most illustrious of Dark Side sects. Some Sith are even in this state permanently (Darth Maul, Darth Sidious after revealing himself.)
** [[TheThrawnTrilogy Grand Admiral Thrawn]] from TimothyZahn's ''Star Wars'' spinoff novels is a Chiss, a race of aliens closely related to humans but with blue skin and featureless glowing {{red eyes|TakeWarning}}. He's a [[WickedCultured gentleman]] [[TheStrategist military]] [[MagnificentBastard commander]] of a villain, rather than someone who will flip out and burn you with laser beams from his eyes, and while he's definitely a bad guy he's complex and not strictly ''evil''. The glow is nonetheless unsettling, and [[EyeLightsOut goes out when he dies]].
** Other Chiss show up elsewhere in the EU. While the most antagonistic any of the named ones has been was around the level of an ObstructiveBureaucrat, they ''all'' have eyes like that, and they all tend to have a little of Thrawn's inscrutability.
** [[HandOfThrawn Flim]] simulates the glow with "self-powered surface inserts".
* Subverted in ''Literature/{{Discworld}}'' with [[foldercontrol]]

[[folder: [[The Grim Reaper Death ]]
]], who has glowing ''[[ColourCodedForYourConvenience blue]]'' [[GlowingEyelightsOfUndeath eyelights]] (unless he's angry) and is a lovable example of TheSpock. It should be pointed out that the blue eyes in question are STARS and that in moments of "emotional" stress (Death can't really do emotions; no glands) they go supernova. Yes, you heard me, his eyes explode when he's angry.
** Also subverted, and inverted, with the {{golem}}s. They all have red glowing eyes as a byproduct of the magic that keeps them alive, but are innately harmless, and indeed most of them are [[RestrainingBolt prohibited]] from acts of violence even in their own self-defense. However, because of their implacable work ethic, [[UncannyValley near-human appearance]], and glowing eyes, people tend to be creeped out by them, and unprovoked attacks of humans on golems are not uncommon.
* Ba'alzamon from ''Literature/TheWheelOfTime'' has eyes that occasionally appear to be pits of fire. After he's defeated, his body has its eye sockets burned out.
* Precision, does this a lot in ''HellsChildren'' by Andrew Boland.
* In Fiona Patton's TalesOfTheBranionRealm novels, royals have literally flaming eyes. In one book a four-year-old sovereign stares so hard at one of her vassals as she argues with him that her eyes grow hot and a "red-hot nimbus of flame" rises up between them. The man, old enough to be her grandfather, hastily submits to her will.
* Sorcerers in ''Literature/SecondApocalypse'' have very bright glowing eyes (and mouth) when they sing their spells. In cases where extreme power is invoked this extends to a whole-body glow.
* In the ''Series/DoctorWho'' tie-in novel ''Forever Autumn'', the aliens attack the Doctor & co. using [[spoiler: possessed cats, and later, children]] whose eyes glow green.
* In ''Literature/TheIslandOfDoctorMoreau'', the first definite sign Prendick sees that M'ling isn't just an ugly human is when he sees the beastman's eyes flash in the darkness, reflecting light like an animal's.
* ''Literature/TheDresdenFiles'': White Court Vampires have this as a gauge of how far into their "super vamp" mode they've gone. If they're normal, you're looking at a dangerous predator. If they're all white, back away slowly and then get out of dodge. If they're ''silver'', [[OhCrap make]] [[MemeticMutation your]] [[AllYourBaseAreBelongToUs time]].
** Denarians also exhibit glowing eyes -- specifically, the Fallen themselves will manifest eyes (usually green) when they are startled, angry, or in combat. They're not required to be in the same places as their hosts' eyes (which, due to VoluntaryShapeshifting, can be whatever shape, color, or number the host wants), and are usually on the forehead. As for the "of Doom" part, well, start with a FallenAngel and go from there.
** When Bob is awake, his skull sanctum's orbital sockets develop glowing orange sparks for "eyes". Normally they're not this trope, but when they turn blue in ''Literature/DeadBeat'', it means his ''very scary'' hidden evil side has taken control. [[spoiler: In ''Literature/GhostStory'', his Evil Bob side has become an independent entity with creepy blue eye-sparks.]]
* In ''Literature/ASongOfIceAndFire'' the wights, corpses on the control of The Others, are described to have piercingly blue eyes, in this vein.
* The ghost of Madeline Stanhope exhibits these after bonding to the Venebretti necklace in ''Literature/TheNecromanticMysteriesOfKyleMurchisonBooth''.
* Beka Cooper, the protagonist of ''Literature/ProvostsDog''. She doesn't have any evil side or DemonicPossession, just IcyBlueEyes that get really ''intense'' when she's angry. People who see her like this assume she's a mage laying a curse, a fear she uses to her advantage on a couple of occasions.
* Both the good and bad guys of ''Literature/TheStormlightArchive'' have them. {{Justified}} in the case of the heroic Knights Radiant, whose eyes glow when they've inhaled a bunch of [[{{Mana}} Stormlight]] and are about to annihilate some evil. [[spoiler: On the bad side, ''Literature/WordsOfRadiance'' reveals that Parshendi eyes glow red when they become Voidbringers.]]
* JC Chance of the ''Literature/GhostFinders'' novels acquires brilliantly-shining eyes from the mysterious Light after his near-death experience in the London Underground. Unlike most heroic examples, it's not temporary or limited to battle, so he has to wear heavy dark sunglasses to go out in public.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/StargateSG1'':
** The Goa'uld do this for intimidation, as well as involuntarily when taking on a new host or dying. Slightly subverted in the fact that the Tok'ra, the good alien cousins of the Goa'uld, also show off their glowing eyes. But they usually nod before, and that's an indication that the symbiont is going to talk, not the host.
** The Doci in seasons 9-10 does this when possessed by the Ori, as does Adria on her own, both before and after ascending.
* Lyta on ''Series/BabylonFive'' has both a Glowing Eyes Of Doom mode when under Vorlon influence and a glossy black eyes mode when resisting (or influenced by) the Shadows.
* ''Series/BuffyTheVampireSlayer''
** When Willow does some serious white magic in the last episode, she gets a pair of completely white glowing eyes.
** Buffy gets a pair in "Primeval" as a result of the enjoining spell.
* ''Series/{{Carnivale}}'': Ben Hawkins sometimes has glowing white eyes when doing something seriously holy.
* ''Series/{{Heroes}}'': Isaac and Peter [[spoiler:along with Sylar -- once he steals Isaac's power -- and later Matt, for no apparent reason,]] get glowy eyes when their in their precognitive trances. Ted, the Radioactive Man, gets glowy eyes when he's about to ''[[SuperpowerMeltdown explode]]''.
* In ''Series/{{Scrubs}}'', when The Janitor makes the grave mistake of saying a new attractive latina nurse looks like a "young Carla", Carla gets glowy eyes and conjures up a powerful wind that blows all throughout the hospital (in an obvious ShoutOut to {{Storm}}) and emits a high-pitched scream that breaks Dr. Kelso's glasses and shatters Turk into a million pieces. ("So ''that's'' why they call him Glassman!") This all happens in an ImagineSpot by the way.
* This trope was also a regular standby of ''Series/{{Charmed}}''. For example, Cole's eyes glowing with fire after a YouKillItYouBoughtIt turns him into the BigBad in season four.
* In the ''Series/StarTrekTheOriginalSeries'' episode "Where No Man Has Gone Before", Gary Mitchell[[spoiler: is zapped by the galactic barrier, his eyes start to glow, and his psi powers grow exponentially. He goes [[WithGreatPowerComesGreatInsanity power-mad]] and [[FallenHero murders]] a [[RedShirt crewmate]]. In the end, Kirk is forced to kill him.]]
* ''Series/DoctorWho''
** The Master in the MadeForTVMovie had constantly glowing green, cat-like eyes which he concealed behind sunglasses and used to instantly hyptonise Chang. The eyes are a continuity nod to the final story of the original series, "Survival", in which the Master was infected and under the influence of the Cheetah Planet that gave his ''last'' incarnation SupernaturalGoldEyes.
** Another example would be Rose when she absorbs the Time Vortex energies. When the Doctor takes it out of her, his eyes glow too.
** Ditto Donna when [[spoiler:her Time Lord metacrisis brain kicks in.]]
** In the episode "42", those who become possessed by the sentient sun -- including the Doctor -- have burning orange eyes.
** In [[Recap/DoctorWhoS21E2TheAwakening "The Awakening"]], the Malice has glowing green eyes.
** Actually justified in the episode "Smith and Jones", where the villain's eyes are glowing because they're reflecting the discharges coming from the MRI scanner.
* Most werewolves on ''BigWolfOnCampus'' have eyes like this. Tommy being the most obvious example.
* ''Series/MightyMorphinPowerRangers''
** When Tommy Oliver is BrainwashedAndCrazy, his eyes would occasionally glow neon green.
** The original Megazord, the Mega Dragonzord, and the Thunder Megazord would have their eyes flash while performing their {{Finishing Move}}s.
* In an episode of ''Series/HowIMetYourMother'' entitled "Slapsgiving 2: Revenge of the Slap", we see Lily's "you're dead to me" look, which is kind of an overly dramatic DeathGlare. The camera zooms in on her face, her hair starts swirling around, she starts breathing intensely, and her eyes light up with a fiery glowing.
* Johnny B. of ''Series/MisfitsOfScience'' developed glowing eyes when his electricity-based powers were fully charged up.
* ''Series/BattlestarGalacticaClassic'''s robotic Cylons have one glowing red eye that slide back and forth with a scary metallic noise. Also, in some posters/still images for [[Series/BattlestarGalacticaReimagined the Reimagined Series]], the humanoid Cylons sport glowing red eyes as well, though this isn't in the actual show.
* Angels from ''Series/{{Supernatural}}'' would occasionally have glowing eyes especially when using their power. The big example would be Sam whose eyes would glow [[spoiler: whenever Gadreel would take over]].
[[/folder]]

[[folder:Music]]
* Some of the kids in the video for [[http://www.youtube.com/watch?v=840B27zYfOk&feature=fvw "Total Eclipse of the Heart"]] by Bonnie Tyler. They're vampires. The song was originally written for an unproduced vampire musical and was later reused for ''Theatre/TanzDerVampire''.
* Music/{{Disturbed}}'s {{Mascot}}, "The Guy".
* Music/PeterGabriel has them on [[http://www.hardformat.org/wp-content/uploads/2010/12/peter-gabriel-1-4.jpg the innersleeve]] of his first solo album.
* Music/MichaelJackson in the infamous twist ending of his music video Music/{{Thriller}}.

[[folder:Pinball]]
* In Creator/WilliamsElectronics' ''Pinball/{{Sorcerer}}'' pinball, the Sorcerer's eyes on the backglass glow and flash during the game.
* Skull the Bone Head in ''[[Pinball/NoFearDangerousSports No Fear: Dangerous Sports]]'' has these.
* The EvilSorceress in ''VideoGame/RuinerPinball'' has glowing neon green eyes.
* The Phantom in ''Pinball/ThePhantomOfTheOpera'' has these, thanks to two well-placed lamps.
[[/folder]]

[[folder:Puppet Shows]]
* The main villain on ''Series/{{Thunderbirds}}'', known as The Hood, has eyes that glow yellow when he uses his mesmeric powers.
[[/folder]]

[[folder:Tabletop Games]]
* In the original ''TabletopGame/VampireTheMasquerade'', the single-dot Protean power was "Eyes of the Beast" or "Gleam of Red Eyes" depending on the edition. Aside from making the vampire in question's eyes glow red, which was great for intimidating some characters, a vampire using it could see in deepest night as though it was a clear day at noon.
* Seemingly ''everyone'' in ''{{TabletopGame/Warhammer 40000}}'' has these. It can only be assumed that any face-concealing helmet will have [=LEDs=] in the eyepieces. That said, the Salamanders chapter of the Adeptus Astartes actually DO have them: glowing red orbs that emit heat, with no pupil or iris.
* ''TabletopGame/DungeonsAndDragons''
** Tieflings in the 4th Edition. Technically, they don't actually ''glow'', but the fact that they're always a solid, often metallic, color seems to create a similar effect. For bonus points, they're often gold or {{red|EyesTakeWarning}}.
** In 3rd Edition ''Dungeons & Dragons'', psionic characters would gain glowing eyes whenever they used many of their powers.
** Certain spells such as "Arcane Sight" make a person's eyes glow blue, and Darkvision can make a character's eyes flash or glow red.
** First Edition's ''Oriental Adventures'' also has the "Fiery Eyes" spell, which makes the caster's eyes glow with an unnatural fire.
* In the ''Palladium Fantasy RPG'', a character could be "cursed" with glowing red eyes, which actually give him increased stats for the purposes of intimidation.
* In the ''Warcraft'' RPG, at least in the first one, night elves (and perhaps high elves also; don't have now the sourcebook) are described to have no pupils and glowing eyes, especially under the moonlight.
* You can give yourself custom cybereyes in ''TabletopGame/{{Shadowrun}}'' with this effect.
[[/folder]]

[[folder:Urban Legends and Myths]]
* The West Virginia crypid Mothman's eyes are legendarily red, and often the ''only'' thing the witness will see (and sometimes be hypnotized by).
[[/folder]]

[[folder:Video Games]]
* Spiders in ''VideoGame/{{Minecraft}}''
* In ''VideoGame/{{Warcraft}} III'', [[TheBerserker Grom Hellscream]] had glowing red eyes, caused by his embracing demon rage with open arms. The glow dies away a moment before his death because he killed the demon who caused the rage. In the expansion Frozen Throne, Arthas gets glowing blue eyes after fusing with the Lich King Ner'Zhul.
* ''VideoGame/WorldOfWarcraft'' (see also GlowingEyes for less sinister examples):
** The Warlock class's demon {{summon|Magic}}s have glowing eyes (except the Felhunter, whose eyes are so tiny as to be practically invisible).
** The demonic eredar have glowing yellow eyes (although that differs from their non-demonic draenei counterparts only in colour).
** Fel Orcs, who achieved their state by drinking a demon's blood, have glowing red eyes.
* In the ''{{VideoGame/Tekken}}'' series, Kazuya Mishima's left eye glows red as of the 4th game, either because of the Mishima bloodline's Devil Gene, or his resurrection by G Corporation. Mokujin, as well, though his aren't really evil as much as an indicator of evil.
* ''{{Franchise/Metroid}}'':
** Ridley has a pair of yellow-orange ones; his Space Pirate lackeys share this trait in the original ''{{VideoGame/Metroid Prime}}''.
** The main villain of ''Prime'', Metroid Prime itself, has glowing eyes, but in deep crimson.
** Phazon-corrupted characters in ''[[VideoGame/MetroidPrime Metroid Prime 3: Corruption]]'' sport glowing blue eyes, including [[spoiler: Rundas, Ghor, Gandrayda, and Samus herself - the last being visibly reflected in her visor, and growing worse throughout the game.]]
* Dracula of ''Franchise/{{Castlevania}}'' fame has glowing {{red eyes|TakeWarning}} - as if it weren't already obvious that he's not someone you want to mess with...
** Joachim of ''Lament of Innocence'' and Walter of the same game display this, too, when they're showing the hell off with magic - Walter in a cutscene notably creepier than most of the others.
* ''VideoGame/DragonAgeII''
** [[spoiler:Meredith has these when you fight her as the FinalBoss]] thanks to [[spoiler: the [[ArtifactofDoom Lyrium Idol found in the Primeval Thaig]]]]
** Anders also gets these when he goes into Vengeance mode at various points throughout the game (or, [[SuperMode when you manually activate Vengeance to increase his damage in combat]]). How doom-y the eyes are is somewhat open to interpretation.
* Although the Hummer robots of ''{{VideoGame/Marathon}}'' are pretty much a joke, their eyes glow in the dark and may cause pants-crapping. Oh yeah, and what's worse is when you see the juggernaut's eyes... The only difference is that the juggernaut is DAMN FAR FROM A JOKE.
* The Witch from ''VideoGame/Left4Dead''. Oh God, the witch...
* The Heartless of the ''Franchise/KingdomHearts'' series, at least those with visible eyes, do this constantly. So does Sora in his Anti Form.
* Common in {{fighting game}}s, especially with possessed or boss characters. Akuma and Evil Ryu from the ''Franchise/StreetFighter'' series always have their eyes glowing red to show they're under the influence of [[SuperpoweredEvilSide Satsui no Hadou]]. M. Bison has glowing white eyes in every game he's appeared in outside of ''VideoGame/StreetFighterII''.
* ''VideoGame/SuperSmashBros Brawl''
** Fighters put their eyes all glowy and get a fiery BattleAura when they grab a Smash Ball, which gives them a somewhat diabolic look. [[http://www.smashbros.com/wii/en_uk/characters/images/mario/mario_070529b-l.jpg Check out yourself]].
** However, Captain Falcon and Meta Knight already have these to begin with, and Mr. Game & Watch averts this by having no eyes to speak of...
** Speaking of ''Brawl'', Link and Toon Link both have "dark" alternate costumes featuring ebony skin, white hair and, yes, glowing red eyes.
* In ''VideoGame/{{Fable}}'' being fully evil causes your eyes to glow red. By this point, you also have demonic horns, insects buzzing around you, a red mist emanating from your footsteps, and townspeople flee at the sight of you.
* In ''VideoGame/KingsQuestVIHeirTodayGoneTomorrow'', you can recognize a shapeshifting genie, trying to lure you to your death, by his flashing golden eyes.
* ''VideoGame/DevilMayCry''
** Subverted with Sparda, who is a demon but had a HeelFaceTurn long before the games to become a sort of [[MessianicArchetype savior figure]] to parts of the human race.
** Played straight with Beowulf, whose {{red eye|sTakeWarning}} glows when he TurnsRed in the third game.
** Also played straight with Dante in the first game and [[spoiler:Nero]] in the fourth.
* Some of the characters in ''TheBlackHeart'' have these; Animus' single eye glows yellow, so do Hashi's eyes. Final has two huge glowing yellow eyes, and their glow amplifies whenever he casts powerful magic. In a particularly sinister variation, Janos is always portrayed as a dark silhouette, and generally with a single red eye glowing.
* In ''VideoGame/{{Doom}}'', the protagonist's eyes on the status bar become glowing and golden when an invulnerability power up is taken (or God Mode is enabled). Combine with a Berserk Pack, and you too can have fun with puns!
* Similarly, the protagonist in ''VideoGame/Wolfenstein3D'' -- but only on enabling of God Mode (no invincibility powerups in that game).
* ''VideoGame/CityOfHeroes''
** Several different forms of these are costume options. These range from a face-type (which predates costume auras) with solid-color eyes, to Electric Eyes, Fiery Eyes, Smoky Eyes, Sparkly Eyes, and more.
** Also, human-form Kheldians' eyes glow when using their powers as an indication that they're channelling power from their alien halves.
* Continuing from the ''Anime/MobileSuitGundam'' example in the anime section, in a number of games, most mobile suits will have their eyes momentarily glow before some of the more dramatic attacks. By the latest SD Gundam game, G Generation Spirits, pretty much every single Mobile Suit in the game will have a freeze frame where nothing moves except the background and the glowing eyes of the attacking unit. Occasionally matching certain suits with certain pilots will give even more dramatic glowing eye shots. The best is whenever Char Aznable pilots his Sazabi, which provides a particularly menacing image. Of course, it IS a Zeon MS....
* Sam Fisher of ''VideoGame/SplinterCell'' is nearly always pictured wearing his night-vision goggles, with the glowing green eyepieces as a visual reference to this trope. He's not superpowered, but he's certainly not someone you'd ever want to anger.
* In ''VideoGame/TheLegendOfZeldaOcarinaOfTime,'' Ganondorf's eyes start glowing hellishly just before he goes into OneWingedAngel mode.
** In the HD remake of ''VideoGame/TheLegendOfZeldaTheWindWaker'' a new graphical effect added to the game is enemies eyes have a noticeable glow to them.
* Those infected by the UnstoppableRage in ''VideoGame/MortalKombatVsDCUniverse'' have this.
* The four fiends of ''VideoGame/FinalFantasyIV'' seem to have this, whether or not it's due to graphical limitation is debatable.
* Waluigi exhibited these whenever he scored a point in ''VideoGame/MarioTennis'' for {{Nintendo 64}}.
* In ''VideoGame/{{Overlord}}'', [[PlayerCharacter YOU]] have these.
* In ''VideoGame/{{Geneforge}}'', people who use many canisters frequently develop glowing eyes. They're not necessarily evil, but they are {{power|Glows}}ful and [[WithGreatPowerComesGreatInsanity frequently unstable]]. It may be {{in|vokedTrope}}tentional, rather than a random side effect -- a character in the first game says glowing eyes are "designed to engender respect."
* The Little Sisters in ''Franchise/BioShock'' have glowing eyes until they're rescued.
* ''VideoGame/FreeSpace'''s Shivans have ''seven'' Glowing Eyes Of Doom. [[http://www.nightsolo.net/fs2guide/shivan1.bmp In a V shape.]] All of them are {{red|EyesTakeWarning}}.
* The MoonRabbit Reisen Udongein Inaba from ''{{VideoGame/Touhou}}'' has these. She has the ability to drive people [[MindRape insane]] by using her eyes to screw around with wave lengths, which also allows her to make illusions and such. When you fight her, a pair of seriously freaky GIANT RED EYES appear in the background to signal that she's screwing with you. All the more fun, considering that her last [[CallingYourAttacks spellcard]] turns her bullets invisible.
* The three core characters in ''VideoGame/DisgaeaHourOfDarkness'' have these. Laharl and Etna show them when they're angry, whereas Flonne also sports them when she's [[{{Otaku}} overly excited]]. Bonus points for her eyes lighting ''on fire'' either way.** [[VideoGame/Disgaea3AbsenceOfJustice Raspberyl]] also gets these when she's mad.
* In ''VideoGame/Jak3Wastelander'', Jak's Light form has glowing white eyes--a stark contrast to his [[SuperpoweredEvilSide Dark form]]'s BlackEyesOfEvil. While he might ''look'' rather angelic with those massive, radiant wings, he can also freeze time and then blast the hell out of you with [[ThereIsNoKillLikeOverkill the Supernova]].
* In ''VideoGame/ArcanaHeart'', the PerversePuppet that [[CreepyChild Lieselotte]] carries around has these as a side-effect of her dead sister possessing it.
* All of ''VideoGame/{{Persona 4}}'''s shadows have these when in human form.
* In ''VideoGame/{{Killzone}}'', the Helghast combine their {{gas mask|Mooks}}s with these.
* In the opening cutscene of ''VideoGame/TitanQuest'', it is shown that the Gorgons' tendency to turn people into stone with their gaze is voluntary; you can tell when one is about to use this power because her eyes will glow. [[GameplayAndStorySegregation they never try doing this to player characters.]]
* In ''VideoGame/KatamariDamacy'' and all ascending games, when you fail, the King's eyes will glow and make a speech on how much you fail.
* In ''VideoGame/StarCraft'', all the Protoss (and most of the Zerg) have glowing eyes
* ''VideoGame/BlazBlue''
** The Kaka clan have glowing eyes. All. The. Time. They're descended from a living weapon, but are largely comical and harmless. Even the playable member, Taokaka, is a comic relief {{Cloudcuckoolander}}.
** Hazama/[[spoiler:Terumi]] has Glowing Eyes Of Doom in the ''Continuum Shift'' trailers, [[spoiler:and when revealed as the TheManBehindTheMan in ''Calamity Trigger'']]
* For some no doubt insane reason, [[VideoGame/TheKingOfFighters Kim Kaphwan]]'s eyes have been known to become sparkling white spotlights when he decides to start kicking evil in the ass.
* ''VideoGame/BaldursGate'': Sarevok's eyes glow yellow/golden, at least sometimes. Even [[spoiler: in his portrait in ''Throne of Bhaal'' when he's no longer a Bhaalspawn.]]
** FanFiction likes to extend this to [[spoiler: the player character as well, when they get really mad or something, for obvious reasons]].
* ''Franchise/ResidentEvil''
** Albert Wesker from ''VideoGame/ResidentEvilCodeVeronica'' to ''VideoGame/ResidentEvil5'' has this in addition to {{red eyes|TakeWarning}} with [[HellishPupils slitted pupils.]] Strangely enough, they visibly glow through his [[SunglassesAtNight trademarked sunglasses,]] but not when he takes them off, so it's probably more for dramatic effect than anything.
** The zombified members of Wesker's private army have glowing red night-vision goggles. Wesker's eyes flashing red through his shades may be a ShoutOut to ''Franchise/{{Terminator}}''.
* ''VideoGame/NeverwinterNights''
** A character reaching twentieth level as a monk will get glowing eyes, presumably reflecting their becoming more than mere mortals as per the 20th-level class property.
** The 1.69 patch gave the Valsharess glowing eyes, which made her look a lot less realistic.
* In ''VideoGame/GodHand'' the mooks will gain glowing eyes when there's a {{demon|icSpiders}} about.
* Guilty Spark 343 from ''Franchise/{{Halo}}'' is basically a floating mechanical eyeball. His eye goes [[RedEyesTakeWarning from blue to red]] when he's enraged beyond rationality.
* In the arcade version of ''VideoGame/DoubleDragon II'', the boss Abore has glowing red eyes and ''Franchise/{{Terminator}}'' style {{sunglasses|AtNight}}; is he supposed to be a cyborg?
* In ''VideoGame/MonsterHunter'' (more specifically ''Monster Hunter Tri'') a hunter can forge the Helios armor set, in which the "eye slots" glow a sort of light blue. It doesn't really inspire doom (in fact you'd probably get some praise from fellow hunters) except for the monster you hunted to make it, an ''Elder Dragon'' named Ceadus. Who is nearly 60 meters long and causes earthquakes to an ''entire island'' whenever he rams it with his horns.
** A lot of monsters also exhibit this themselves, though usually when enraged. All of the aquatic monsters have it when fighting them underwater, which works as a gameplay element to help you see where they are more easily as it is very hard to see underwater, and also to inspire terror as you may not see the monster behind you until it rears its head and shows you the glowing eyes.
** A notable example among land monsters is the Nargacuga, who is usually fought at night and whose eyes glow bright red. They glow more intensely when the monster is enraged, leaving trails as it moves around. This is mitigated somewhat if you break its face, which has the result of [[EyeScream a scar where one eye used to be]], though the other eye still glows.
*** Lucent Nargacuga takes this a step further: though its eyes still glow, it is capable of turning completely invisible, so its eyes (when in rage mode) are the only means by which you can effectively track its motion.
* Monsters' eyes glow a [[SicklyGreenGlow sickly greenish shade]] when they're subjected to MindControl in ''[[{{Creator/Nitrome}} Parasite]]''.
* The Raincoat Killer in ''Videogame/DeadlyPremonition'' has what appear to be red-tinted headlights where his eyes should be.
* ''VideoGame/MassEffect2''
** If Shepard moves toward the Renegade side of the KarmaMeter, their eyes begin to glow red as their more violent, aggressive, and ruthless nature exacerbates the cybernetic implants in their body.
** Also invoked when Harbinger takes control of a Collector soldier.
** In the [[VideoGame/MassEffect1 first game]], [[BigBad Saren]] had these, as well, due to his Reaper implants. [[spoiler: Exactly the same. They're an early hint that he's a Reaper thrall.]]
* In the ''VideoGame/LegacyOfKain'' franchise, the Hylden and [[MindControlEyes those possessed by them]] have glowing green eyes. The Hylden seen at the time are AlwaysChaoticEvil. [[spoiler: Being in the local idea of Hell for untold millenia does that.]] Oh, and they try to take over the world and kill everyone. And [[GenreBlindness most humans have no idea]].
* The [[DemonicSpiders Replica Ninjas]] in ''[[VideoGame/FirstEncounterAssaultRecon FEAR]]''.
* ''All'' demons in ''VideoGame/ShinMegamiTenseiStrangeJourney''. It's a callback to the earliest days of the series.
* The Zuul from ''VideoGame/SwordOfTheStars'' are depicted with glowing eyes in the artwork.
* In ''VideoGame/{{Bayonetta}},'' Rodin and Bayonetta are talking in the [[spoiler:Gates of Hell Bar]], and Rodin is using [[spoiler:bottles to describe the relationship between Paradiso, Inferno, and the Human world. When he says that heaven and hell are going "straight for each others' throats]]," his eyes glow red behind his sunglasses.
* ''VideoGame/NightTrap'' features these with Sarah (if you're fast enough to see her in the bedroom at the start of the game) and Tony. All of the other vampires have them as well, but only when they show their fangs.
* The ''Series/DoctorWho'' adventure game ''The Gunpowder Plot'' features a shapeshifting Rutan called Lady Winters, who when in human and cat form has bright green glowing eyes.
* Standard for anyone on the receiving end of an Ubercharge in ''VideoGame/TeamFortress2''. The Demoman can get them by taking heads with the Eyelander.
* All of the colossi in ''VideoGame/ShadowOfTheColossus'' have these. When they're simply moving around, their eyes are blue, but when they're attacking or being attacked, they [[RedEyesTakeWarning turn orange.]]
* Asura from ''VideoGame/AsurasWrath'' after climbing out of Naraka has eyes permanently in this state, and they glow their former red color on occasion. His master Augus has these naturally, but [[spoiler: they are white holes because Augus is blind.]] They only return to normal once [[spoiler:Asura destroys Chakravartin and frees Mithra]].
* The [[InvincibilityPowerUp Pentagram of Protection]] in ''VideoGame/QuakeI'' makes the Ranger's eyes glow.
* Killian in ''VideoGame/PerfectDark Zero'' has glowing red eyes, likely due to cybernetic augmentation.
* In ''VideoGame/{{Freelancer}}'', Nomad-infected people in cut-scenes make their eyes glow blue when they really mean business.
* In ''VideoGame/DevilSurvivor2'', team member Io Nitta has them [[spoiler:when she channels the spirit of Lugh, an Irish sun god, as a (temporary) enemy. Toxic green eyes, to be precise.]]
* In ''VideoGame/TheElderScrollsVSkyrim'', if you have the Dawnguard DLC installed, vampires have glowing yellow eyes.
* Even ''VideoGame/GearsOfWar'' has this; sometimes played straight, sometimes averted. The Locust Horde (the main antagonists of the series) outfits many of their war beasts with helmets that have multiple glowing eye-pieces to fool human on-lookers that they're fighting multi-eyed, alien beast. The truth is, few Locust creatures actually have more than two eyes, let alone glowing ones. The exceptions being the Kryll, who have two eyes, and the Corpsers, who have four.
** A perhaps even greater example of this are the Lambent. Once something is exposed to Imulsion, the series' fictional fuel, it starts mutating into a horrible beast, twisting, shifting or even mummifying... but every single Lambent to date (that has eyes, mind you) has had glowing eyes. Seeing how the Lambent want to consume everything and every time you kill them, they explode, this trope is pretty justified.
* In the ending of AlphaPrime, [[spoiler:Arnold]] appears to come back from the dead with glowing green eyes. This is not a good sign for the people he's on the ship with.
* [[spoiler:Morrighan's]] eyes in ''VideoGame/{{Mabinogi}}'', [[spoiler:when they aren't shut]], are this trope combined with DeathGlare. Needless to say, if you ever see them like this, chances are some serious shit is about to go down.
* The vendor in ''VideoGames/DustAnElysianTail'' has, as Fidget puts it, "glowing evil eyes of evil". As it turns out, he's not evil at all and quite eager to do business with you.
* The last stage of 1985 coin-op ''Son of Phoenix'' (aka ''[[MarketBasedTitle '99: The Last War]]'') is set in a place which has the Parthenon, the Pyramids ''and'' the Easter Island Statues (presumably replicas of these things). At some points of the battle, one or more of the statues' eyes glow red.
* Whenever a villain is possessed by Towa in ''VideoGame/DragonBallOnline'' and ''VideoGame/DragonballXenoverse''.

* Dahlia Hawthorne from ''VisualNovel/PhoenixWrightAceAttorney: Trials and Tribulations'' does this [[spoiler: in the first case after she is revealed to be the murderer of Doug Swallow]]. Also, [[spoiler: her mother]] Morgan Fey tends to do this when she gets angry.
* Rider in ''VisualNovel/FateStayNight'' when she actually shows her eyes... Probably because they aren't really eyes so much as (apparently) crystallized magical energy that happen to be what she sees with. Oh, and she's [[spoiler: Medusa]]. Figure out the 'of doom' part.
* The dragon's eyes and the dragonslayer's eyes in ''VisualNovel/DraKoi'' glow blue and red respectively when using their abilities. Or at least, the armor's eyes glow. Comes to the same thing.

* [[spoiler:The Hypersuit]] from ''WebComic/{{Hyperboy}}''.
* Epsilon [[spoiler:Church]] from ''Machinima/RedVsBlue'', embodied by a Monitor (basically a floating eyeball) from ''Franchise/{{Halo}}''. When the eye shifts from blue to red, it indicates that the Monitor is about to fire a [[FrickinLaserBeams laser beam]].
--> '''Epsilon:''' You will fear my laserface!!
* Cinder Fall from WebAnimation/{{RWBY}} manifests these when she starts throwing fire around.
* Chicken of ''WebAnimation/ChickenAndMoose'' sometimes has these, usually coupled with bursts of frightening lucidity.

[[folder:Web Comics]]
* Fatale from Webcomic/AverageJoe normally has her eyes glowing red behind her mask. It seems to only occur when she's angry, but [[http://ajcomic.com/?p=152 she]] [[http://ajcomic.com/?p=242 spends]] [[http://ajcomic.com/?p=470 a lot]] [[http://ajcomic.com/?p=591 of]] [[http://ajcomic.com/?p=665 time]] [[http://ajcomic.com/?p=672 angry]].
* In a ''VideoGame/DragonFable'' fan-fic, Dan's eyes glow red when doom takes over him.
* Ciro and Kareems eyes glow when they "go dark" in ''[[http://centralcitytower.deviantart.com/gallery/#/d5miak2 Project 0]]''. Played with in that it doubles as [[ByTheLightsOfTheirEyes a cartoonish trick]].
* The title race of Tarol Hunt's ''{{Webcomic/Goblins}}'' sport something close when angered. It's not quite glow -- it's their widened pupils. Big Ears on the other hand did receive these when he acquired his enchanted paladin gear.
* Magic users in ''Webcomic/DominicDeegan: Oracle for Hire'' have their eyes glow when particularly focused.
* ''Webcomic/GunnerkriggCourt''
** Reynardine does this occasionally.
** [[spoiler:His cousin]] Coyote's eyes (and he has many) glow when he's [[http://www.gunnerkrigg.com/archive_page.php?comicID=492 showing off his awesome power]], which, if he wanted to use it that way, could mean certain doom for just about anyone.
* Spoofed in [[http://www.adventurers-comic.com/d/20050129.html these]] [[http://www.adventurers-comic.com/d/20050201.html two]] ''{{Webcomic/Adventurers}}'' comics.
-->'''Tesla:''' I can't believe you would do something like that! We lost people on the force to glowy-eye-soul-stealing-related complications!
* ''Webcomic/{{Lackadaisy}}'': While not ''literally'' glowing, Viktor's eye is often noticeably shaded lighter than his surroundings would logically cause it to be, giving it a "glowing" look (aka The Glare Beam). This is especially noticeable during the firefight with the pig farmers, which takes place in a darkened garage. During this scene, everything is shaded so as to give an impression of pitch blackness... except for Viktor's scary, glare-y eye. The fact that he's a ''cat'' doesn't hurt either.
* ''Webcomic/LookingForGroup''
** Richard has glowing yellow eyes. [[http://www.youtube.com/watch?v=fcbazH6aE2g One could say he fits the trope.]] (But then, he ''is'' [[GlowingEyelightsOfUndeath undead]].)
** And Maikos too.
* ''Webcomic/TheOrderOfTheStick''
** Celia's eyes glow blue [[http://www.giantitp.com/comics/oots0070.html when she's angry]], or possibly when she shoots lightning, as these tend to happen at the same time. She also likes to use them [[http://www.giantitp.com/comics/oots0529.html against her mother]], apparently.
** This is common with enraged spellcasters in ''The Order of the Stick''. [[http://www.giantitp.com/comics/oots0160.html Samantha the Sorceress]] and later [[http://www.giantitp.com/comics/oots0597.html Vaarsuvius]] both glow with an awesome power.
* ''Webcomic/SluggyFreelance''
** Lord Horribus's eyes glow so fiercely when he's mad that ''flames'' start to creep out of them (which almost always goes along with a fiery BattleAura).
** Also Gwynn, when she gets so angry that the powers of K'Z'K or the ''[[TomeOfEldritchLore Book of E-Ville]]'' activate in her automatically.
** Bun-bun once manifests [[RedEyesTakeWarning red eyes]] (not unambiguously drawn as glowing, but ''he'' starts glowing red next) when he gets absolutely enraged.
* In ''Webcomic/CollegeRoomiesFromHell'', Dave's eyes glow when he's about to unleash his laser beams.
* In ''Webcomic/TheKamics'', the ex-valkyries, Gertrude, Brunhilda & Nikki's, eyes glow when they are angry. Oddly enough they usually glow the same color as their hair color.
* The SevenDeadlySins of ''Webcomic/{{Jack|DavidHopkins}}'' have glowing eyes, including the titular character, whose eyes grow black and become pin pricks of light when he's ticked off. The Devil subverts the trope by having completely [[BlackEyesOfEvil dark black eyes.]]
* ''Webcomic/EightBitTheater'': [[HeroicComedicSociopath Black Mage.]] Complete with the hellish aura that was last seen when Black Mage confronted the personification of his sins ([[spoiler: himself]]), and before that, seen on Black Mage when he [[LikeABadassOutOfHell took over hell]]. [[spoiler:Not surprisingly, Black Mage was using the power he gained from killing the personification of his sins.]]
* [[GamerChick Lilah]] from ''Webcomic/CtrlAltDel'' likes playing ''[[VideoGame/TheSims Sims 3]]''... for a very [[http://www.cad-comic.com/cad/20090601 particular reason]].
* The title characters of ''Webcomic/FreakAngels'' have this when they use their [[http://www.freakangels.com/?p=75&page=4 powers.]]
* Characters who go into [[http://www.goldcoincomics.com/?id=130 Berserk mode]] in ''Webcomic/GoldCoinComics''.
* In ''Webcomic/WapsiSquare'', the golem girls [[spoiler:and Monica]] can make their eyes glow, essentially causing them to function as flashlights. It is fueled by fear, doubt, or anger. A {{golem}} feeling any of those certainly spells danger.
* ''Webcomic/{{Homestuck}}''
** After JumpingOffTheSlipperySlope, [[spoiler: Rose]]'s eyes glow white. Inverted with [[spoiler: Kanaya]], however; after [[spoiler: coming back from the dead]], everything glows ''except'' [[spoiler: her]] eyes.
** More literally, Sollux has glowing red/blue eyes -- and is a "Mage of Doom"
* [[http://www.levelmanga.com/level.php?page=44&episode=4&large=true&cover=false leveL]]'s main character combines this with some glowing goo oozing from his wrists. Sure, he's always been a pretty timid guy, but when you see a kid that glows that much, and advances towards you with a creepy smile, you have to admit that something ain't right.
* In ''Webcomic/{{Unsounded}}'', Duane Adelier's[[our-liches-are-different]] eyes occasionally glow.
* The [[http://www.egscomics.com/?date=2011-04-18 Bulldog Dragon]] from ''Webcomic/ElGoonishShive'' has these.
* In ''Webcomic/{{Endstone}}'', rocking the Banestone, or the ArtifactOfDoom, [[http://endstone.net/2011/06/23/6-04/ gives Jon glowing eyes]].
* In ''Webcomic/TheAdventuresOfShanShan'', [[http://shanshan.upperrealms.com/view.php?pageid=017&chapterid=1 Karmavore]].
* In ''Webcomic/AxeCop'', after his gaining superpowers including eye beams, Fwinky Dog's eyes can emit a fierce green radiance when stuff gets real, as [[http://axecop.com/comic/episode-125/ here]].
--> "I think those dogs might be ''bad guys'' trying to ''steal my Fwinkys''. I'm gonna ''fight them''."
** The Water Queen's eyes light up for some major uses of her [[MakingASplash water powers]], such as stabbing an evil alien to death with [[ThereIsNoKillLikeOverkill the entire ocean.]]
* Played straight and subverted in ''Webcomic/SlightlyDamned''. If a demon's eyes are glowing, it could be [[TheBerserker enraged and about to rip you apart]]... or it could just be trying to [[ByTheLightsOfTheirEyes improve its night vision.]]
* Played pretty straight in ''Webcomic/TheSenkari'', whenever Freija's eyes [[HairTriggerTemper start glowing]], it usually means that something bad is about to happen to someone.
* ''Webcomic/TheAdventuresOfDrMcNinja'': Dr. McNinja's eyes glow yellow when he goes into the mode where he can fight ghosts.
* ''WebComic/{{Precocious}}'': Bud and Tiff during Autumn's paranoid delusion about their museum trip. Tiffany again after consuming an entire pot of coffee.

* In ''Roleplay/TheGamersAlliance'', the eyes of demons and half-demons start glowing when they channel their demonic powers and are about to kick some major ass.
* After Creator/MaraWilson got revenge on WebVideo/TheNostalgiaCritic by {{exploit|ed trope}}ing his OldShame, her eyes glowed white as everything else turned red.
* [[BigBad Red/the Hellbeast]] in ''Literature/NESGodzillaCreepypasta''. It's very unnerving.

[[folder:Western Animation]]
* On ''WesternAnimation/AquaTeenHungerForce'', Frylock's eyes glow blue before he zaps you.
* In the ''WesternAnimation/SilverSurfer'' cartoon, {{Galactus}}' eyes glow brightly. So does his mouth when it opens.
* Aang from ''WesternAnimation/AvatarTheLastAirbender'' has these when he's in [[UnstoppableRage the Avatar State]]. Every young Avatar gets Glowing Eyes of Doom when they enter the [[SuperMode Avatar State]] before they learn to control it. However, when they master it and become full-fledged Avatars, they only need to enter it for about half a second to gather power, then they break out the ass-kicking with normal eyes. This is extremely important, because an Avatar killed while in the State breaks the cycle of reincarnation -- there would never be another Avatar again. Avatar Kyoshi is shown using this method (her eyes pulse, then she bends all four elements simultaneously to move ''tectonic plates'') during the episode "Avatar Day". [[spoiler:Aang also uses the master method in the finale, after finally learning to control the Avatar State to keep himself from breaking his Moral Code and killing Firelord Ozai.]]
* ''WesternAnimation/TheLegendOfKorra'': Korra gets her own glowy eyes in the season finale of her sequel-series, when she too goes into the Avatar State for the first time. It's every bit as awesome as ever.
* ''ComicBook/{{Spawn}}'' in the {{HBO}} animated series. That's pretty much ALL you see of his face most of the time. Also Clown/Violator.
* ''WesternAnimation/{{Gargoyles}}''
** The gargoyles develop these when angered; males have glowing white eyes, while females have glowing red eyes. Originally, the writers only gave Demona the glowing red eyes of doom, but the creators thought that would be too silly to base it on evil alignment, and changed it to a natural, sexually dimorphic trait.
** The gargoyle ''clones'' reverse this: males have glowing red eyes and females white, though this may have more to do with being rapid-aged in tanks rather than their being clones, per se.
* ''WesternAnimation/TeenTitans''
** When animated Starfire's eyes go from green with green-tinted whites to solid, glowing green, you don't want to be in her way. And once she gets EyeBeams, this happens whenever they're used. ([[Comicbook/TeenTitans Comicverse]] Starfire's eyes are always [[MonochromaticEyes solid green]].)
** Also, Raven's eyes generally glow solid white when she's using her powers. And if her eyes ever start glowing solid red, it's advisable to run. Especially when they split from two into four. But then, it's probably already too late if that's happened. (Happened in "Aftershock", in season two, without recourse to the Season Four Arc.)
** Terra's eyes glow bright yellow when she's pissed or can't control her powers.
** This is pretty common in ''Teen Titans''. In addition to the above, Trigon has red eyes that glow constantly, Brother Blood's eyes glow red when he uses any of his powers, Blackfire's eyes are purple and glow when she's angry or charging up a starbolt, and Jinx's glow pinkish-purple.
* ''Franchise/{{Transformers}}''
** Similarly, although most of the Transformers in ''WesternAnimation/BeastWars'' have glowing eyes, Dinobot's normally red eyes shine bright green when he's charging up his EyeBeams. On top of that, they ''blink'' by having the lights switch off and then back on, while the actual physical eyes don't close.
** The following picture from ''Anime/TransformersCybertron'': [[http://tfwiki.net/wiki/Image:Cyb_ep41_angry_optimus.jpg]] 'Cons, you should run now.
* ''WesternAnimation/XMen'': Animated Cable's left eye glows white when using his telekinesis (or at dramatically appropriate moments) and red when using his cybernetically enhanced vision.
* In ''WesternAnimation/DannyPhantom'' the title character can make his eyes glow green when he gets serious or angry; it's one of the effects of his ghost powers. Appropriately mocked by Vlad, the series' resident MagnificentBastard, when Danny tries to intimidate him.
-->'''Vlad:''' Ooh, the scaaaaary eyes. ''(fires his {{eye beams}})''
* The eponymous robot in the ''WesternAnimation/DuckTales'' episode "[[Recap/DuckTalesS1E2Armstrong Armstrong]]", when it becomes clear that he's turned on Scrooge.
-->"I...AM...ARMSTRONG. I...AM...YOUR...''FRIEND.'"
* M. Bison from ''WesternAnimation/StreetFighter'' while explaining that he does not whine about it! Well, he '''[[LampshadeHanging did]]''' [[LampshadeHanging state that he got his power]] from a GodOfEvil.
* ''WesternAnimation/{{Metalocalypse}}''
** A few episodes end with the band members' eyes glowing red, notably "Performanceklok", which ends with them watching their therapist being ripped apart by wolves.
** Mr. Salacia's eyes glow white whenever he [[spoiler: uses his EldritchAbomination powers.]] Also, Gen. Crozier's glow any time he is [[spoiler: being controlled by Mr. Salacia.]]
--->"Gosh. Maybe this is weird to say, but... am I the only one who's being made to feel hungry by watching... this? "
* Franchise/GreenLantern John Stewart from ''WesternAnimation/JusticeLeague'' has glowing green eyes as long as he's wearing his power ring -- {{Word of God}} says that it's because he's been a GL for so long that it's more or less "infected" him. He's also one of the few Green Lanterns who doesn't wear a mask. A few other maskless Lanterns have this same effect.
* In ''WesternAnimation/GerryAndersonsNewCaptainScarlet'', Captain Black and [[KillAndReplace anyone possessed]] by the [[ScaryDogmaticAliens Mysterons]], their eyes will glow green either to show the viewer who's working for them, [[MindControlEyes hypnotizing a victim]], or ready to fight the title Captain.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic''
** Twilight Sparkle gets these when she uses some of her more powerful spells.
** Princess Luna also gets these when angry.
** The Mane Six whenever they break out the Elements of Harmony.
** Whenever Rarity uses the magic found in the ''[[Recap/MyLittlePonyFriendshipIsMagicS4E23InspirationManifestation Inspiration Manifestation]]'' spellbook, her eyes glow a sickly green color and she becomes more and more obsessed with making everything pretty.
* On ''WesternAnimation/TheSecretSaturdays'', Zak Saturday's eyes glow yellow-orange whenever he uses his cryptid-controlling powers. His antimatter counterpart Zak Monday bears a bright green glow.
* Gwen in ''WesternAnimation/Ben10AlienForce'' gets these with some uses of her powers. The pilot of ''WesternAnimation/Ben10UltimateAlien'' has Ben getting the same for a moment after using Spidermonkey's SuperMode.
* In WesternAnimation/GodzillaTheSeries Godzilla's eyes would glow a vibrant green, in addition to green flashes along his spines, whenever he used his BreathWeapon.
* In ''WesternAnimation/StaticShock'', many [[DifferentlyPoweredIndividual Bang Babies]], good or bad, have glowing eyes while using their powers. The protagonist's eyes don't glow, but they do have sparks flying in them.
* ''WesternAnimation/ReBoot''
** when Matrix's bionic eye spins around and glows red, you know ''something'' is either going to blow up or die. Even when he doesn't get to shoot something, he obviously wants to.
** Hexadecimal's eyes are ''always'' like this [[spoiler:except for the time she became a sprite.]]
* On ''WesternAnimation/JimmyTwoShoes'', this happened to Heloise once to go along with a SlasherSmile.
* [[RobotBuddy GIR]] in ''WesternAnimation/InvaderZim''. His eyes are always glowing, but when he goes into [[RedEyesTakeWarning Duty Mode]], there's a brief flash from his eyes.
* ''WesternAnimation/GravityFalls'': The Gremloblin's eyes glow yellow when people look into them and see their worst nightmare.
* In ''WesternAnimation/{{Wakfu}}'', [[spoiler:Qilby's]] eyes gain an eerie glow after he [[spoiler:merges with the Eliacube]].
* The Minions of Set from ''WesternAnimation/SamuraiJack'' have bright blue glowing eyes. They also happen to be super strong, super fast, nigh-invulnerable juggernauts that simply cannot be defeated by normal mortal methods, even with enchanted holy weapons like Jack's sword.

[[folder:Real Life]]
* Cats can appear to have this ability, but it's actually more like Shining Eyes of Doom. Cat eyes have reflective membranes (the tapeta) that bounce light which gets past the retina back onto it to increase their night vision. However, the "glow" is all light reflected from the environment and is not a real glow.
** Not surprisingly, the pictures on [[http://www.catsthatlooklikehitler.com/cgi-bin/seigmiaow.pl Cats That Look Like Hitler]] often have "glowing eyes of evil" -- in some cases it's probably deliberate.
** Raccoons are also rather well known for this, as they are frequently spotted at night. [[http://naturalunseenhazards.files.wordpress.com/2012/04/raccoons.jpg Tell me this photo isn't a bit unnerving.]]
* Parrot eyes don't glow, but they do dilate very noticeably -- "flashing". Somewhat akin to a cat's purring or a pet rodent chattering their teeth, this eye flashing might indicate excitement, or warn another that they are very, very PO'd.
* Many creatures ([[SmallReferencePools most familiarly dogs and cats]]) have eyes with an organic mirror (the tapetum) behind the retina, to increase the sensitivity by bouncing light back onto it. In diurnal creatures, this tends to be red (not quite the same thing as the red-eye effect in humans), in nocturnal, crepuscular, and cathemeral creatures such as cats or owls, this tends to be orange, yellow or green, and in dogs, this tends to be blue-green or blue.
* Humans don't have a tapetum lucidim, the red eye effect is simply caused by the flash being too close to the camera lens[[note]]The light from the flash travels into the person's eye, bounces off the retina, and back into the lens. Placing the flash farther away from the lens widens the angle, making it more difficult for the light to hit the retina ''and'' bounce back to the lens. [[AndKnowingIsHalfTheBattle And now you know.]][[/note]]. Animals that do have a tapetum very rarely exhibit the red eye effect unless their eyes are blue; instead you may see eyeshine. In fact, humans that DO exhibit something resembling eyeshine (other than the typical red eye effect) in photos should be checked by an ophthalmologist as it is a common symptom of [[http://en.wikipedia.org/wiki/Leukocoria Leukocoria]] and several other serious (but fairly rare) illnesses.
* The Vampire Squid uses bioluminescence to ''pretend'' to have these.
* There are neon contacts that glow under UV light. Technically, they absorb light at an invisible wavelength and convert it into a visible wavelength before releasing it. This is known as [[http://en.wikipedia.org/wiki/Fluorescence fluorescence]].
* Modernized [[UsefulNotes/RussiansWithRustingRockets T-90 tanks]] carry a pair of infrared targeting jammers (the Shtora system), mounted on either side of the main cannon like eyes. When idling or out of combat, the jammers are off and appear to be regular old searchlights. In combat, they are switched on and [[http://i.imgur.com/gVUuYCE.jpg emit a sinister red glow]].
