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. Though 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, this ''always'' means 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 LightsOffTheirEyes.

A subtrope of KaleidoscopeEyes or TechnicolorEyes. See also: DemonHead, ScaryShinyGlasses, HellishPupils and MindControlEyes. Part of a [[PowerMakeover package deal]] with an EvilMakeover.
GlowingEyelightsOfUndeath is a subtrope. This trope sounds like it should go hand-in-hand with ByTheLightsOfTheirEyes(watch that extra 'f'), but it doesn't.

!!Examples:

[[foldercontrol]]

[[folder: Anime ]]

* For TheHero of ''FistOfTheNorthStar'', Kenshiro has a '''seriously''' evil looking pair of ''red'' GlowingEyesOfDoom whenever you [[TooDumbToLive get him]] [[WhatAnIdiot seriously angry.]]
* The title character of ''HayateTheCombatButler'' resorts to this after being hit by a car. The occupants instantly surrender.
* One of the shinigami in ''DeathNote'' gains these eyes at one point while going for some dramatic kills. Light tends to do this, as well, whenever he's feeling particularly evil.
** Mikami and Misa, too.
* Robots in general tend to do this, too.
** Most infamous for it is the {{Terminator}}.
** Even HumongousMecha do this at times:
*** Zeon mecha from ''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.
*** ''GundamWing'' 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 ''GundamWing'', characters unable to control the [[ForgottenSuperweapon ZERO System]] enter an UnstoppableRage, marked by glowing golden eyes.
***Let's not forget about {{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 ''NeonGenesisEvangelion'' glow white when they enter 'Berserk Mode', which generally means their opponent is doomed. DOOMED. The ''Rebuild of Evangelion'' movies go so far as to have the eyes of the pilot glow at the same, allowing Shinji to flash a particularly nice DeathGlare in pitch darkness.
** ''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 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 ''HigurashiNoNakuKoroNi'' do this both humorously and seriously. Not being able to tell which is which amps up the creep factor.
* The title character of ''RurouniKenshin'' does this when he goes into [[SuperpoweredEvilSide Battousai mode]].
* ''GirlsBravo'' - Humorously done by Lisa, Kosame, Fukuyama when they're pursuing Yukinari, Kirie, and Koyomi respectively, as well as Kirie at one point.
* ''NagasareteAirantou'' - Humorously, as the women close in on their 'prey' like zombies.
* ''{{Inuyasha}}'' every time his SuperpoweredEvilSide takes over.
* The eyes of the Homunculi (particularly Gluttony) occasionally glow ominously in ''FullmetalAlchemist''.
** On a more humorous note, Ed's eyes occasionally do it too when someone insinuates that [[BerserkButton he's short]].
** [[{{CrowningMoment/FullmetalAlchemist}} "There's no need to say anything more,]] [[CompleteMonster Envy]]. [[CurbStompBattle The first thing]] [[PlayingWithFire I'm gonna burn]] [[StuffBlowingUp to ash]] [[UnstoppableRage is your tongue"]]
* ''{{Azumanga Daioh}}'''s Yukari-sensei, after Tomo accidentally hits her in the face with a tray.
* Happens often in the first half of ''DragonballZ'', 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.
* Kazuma's eyes in ''KazeNoStigma'' glow blue when he taps into his full powers, and ''red'' when he's reverted to his SuperpoweredEvilSide.
* Vash The Stampede in ''{{Trigun}}'' does this occasionally, notably in the episode "Diablo". Basically it happens when a bad guy does something bad enough to break through his ObfuscatingStupidity, and when it happens, it's even worse than if he put on the ScaryShinyGlasses.
* Makoto Shishio from ''RurouniKenshin'', after being shot through a wall, looks menacingly at the main characters with GlowingEyesOfDoom.
* Yuusuke from ''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 (in what this editor found to be an unintentionally comedic effect) 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 Yuusuke's GlowingEyesOfDoom have always been blue, these are red, possibly to signify either his new demonic nature or the foreign presence in his body.]]
* In ''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 ''{{Clannad}}'', Kyou's eyes 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.
* Subaru of ''MagicalGirlLyricalNanoha [=StrikerS=]'' 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 first appearance, appearing as a black silhouette with Alucard-style glowing yellow circles.
* Ryoko in ''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 ''[[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 ''{{Genshiken}}'' into a cosplay research club as president, Ohno gets GlowingEyesOfDoom. In fact she gets GlowingEyesOfDoom whenever she gets sufficiently obsessed about something, mainly cosplay-related.
* The Count in ''{{Gankutsuou}}'' does this a few times.
* Two characters from ''{{Mai-HiME}}'' get these - Mikoto ([[EyesOfGold gold]]) and Nao ([[RedEyesTakeWarning red]]).
* When Chika finds a photgraph of Tina and Kaoru In ''AiYoriAoshi'', Tina gets perfectly round GlowingEyesOfDoom 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 ''IkkiTousen'' get these when they summon their inner dragons.
* Ichika from ''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 ''{{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.
* Medusa of ''SoulEater'' is fond of this.
** [[spoiler: Death the Kid]] also starts glowing toward the end of the anime.
* Ichigo Kurosaki in ''{{Bleach}}'' doesn't get fully-glowing eyes, but his normally-brown irises glow blue on a few occasions when he's about to do something particularly powerful.
** Ikkaku's eyes also glow when he [[spoiler:uses his Bankai]]
* Lime in ''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 {{Evil Eye}}s 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 ''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 ''{{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.
* ''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 ''{{Samurai Deeper Kyo}}'' is the GlowingEyesOfDoom upgrade of the Mibu clan's regular [[RedEyesTakeWarning Red Eyes]].
* Used occasionally in ''OnePiece''. One notable ([[CrowningMomentOfFunny and hilarious]]) scene is [[http://www.youtube.com/watch?v=r9zuB6IhU3c during the battle with Oz]].
* Both Alucard and Anderson from ''{{Hellsing}}'' invoke this trope whenever they stop screwing around and are about to curbstomp someone into the ground.
* One of ''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 ''{{Pretear}}'' occasionally gets these when she is angry.
* In the hilarious ''{{Harukanaru Toki no Naka de}} - Hachiyoushou'' OAV episode "Omoi no Arika", [[SmallAnnoyingCreature Kotengu]] manages to induce these in, [[YoungerThanTheyLook of]] [[TheStoic all]] [[ArtificialHuman people]], '''Yasuaki'''.
* Takeda Shingen from ''SengokuBasara'' whenever an epic beatdown is in order. Young BloodKnight Date Masamune also does this whenever he's ''really'' enjoying a fight.
* In KenichiTheMightiestDisciple pretty much every single master in Ryozanpaku shows GlowingEyesOfDoom periodically, and not even when fighting other masters, but rather during the [[TrainingFromHell training]] [[ColdBloodedTorture sessions]] with their own disciple.
** ThisTroper must mention the fact that Ryozampaku's masters are the good guys.
* In ''{{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 ''DarkerThanBlack'', Contractors' eyes glow [[RedEyesTakeWarning red]] when they use their powers. [[GlamourFailure It's almost the only way of identifying them]].

[[/folder]]

[[folder: Comic Books ]]

* When {{Superman}} wants to be intimidating, he likes to appear in shadow with his eyes glowing a fierce red as if ready to fire his [[EyeBeams heat vision]].
* Several ''Comicbook/{{X-Men}}'' characters do this.
** When a villain (or Wolverine) is ''really'' getting on 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.
** Storm's eyes become solid white and glowing when she uses her powers. This carries into almost all adaptations.
** When Magneto gets angry, his eyes glow as well, independent of power usage.
** Primarily in adaptations, a disguised Mystique is frequently revealed to the audience by her eyes glowing yellow (their natural color) briefly.
** Gambit's eyes have been known to give off red energy when he's intended to look particularly badass.
** Cable and his alternate-universe clone X-Man both have glowing left eyes.
*** Only when 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 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 Ultimate X-Men 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.
* In the ''{{Starfox}}'' comic from ''Nintendo Power'', 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 [[{{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 ''{{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.]]

[[/folder]]

[[folder: Film ]]

* ''XMen'' films' Mystique's eyes glow yellow. Sometimes when she is impersonating another character the audience is shown her natural yellow glowing eyes to clue us in that it is really her in disguise, no one in the film sees, of course.
* ''StarWars''' Anakin Skywalker's eyes glow a bright yellow when he goes off to kill all the youngling Jedi. He covers his head with a hood, but you can tell that they glow in the shadow. Also, he is wearing eyeliner. That's what happens when you go darkside.
* Scott Howard, the titular werewolf from ''Teen Wolf'' 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 [[CreepyChild creepy children]] from ''Village of the Damned'' have eyes that glow bright blue whenever they use their PsychicPowers.
* Louis Tully in ''{{Ghostbusters}}'' got glowy eyes after being possessed by Keymaster Vinzdeat Clortho.
* In ''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, that's capable of taking out tanks (and possibly battleships).
* The evil robot kids from ''SpyKids'' have eyes which flash like this, accompanied by an electronic sound effect.
* ''IronMan'''s eyes glow. But the trope is really invoked when, in the darkness, the Iron Monger suit's eyes switch on.
* In the film adaptation of ''{{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 pigmintation, and they're eyes were just a wierd kind of blue.
* If you're in ''StarTrekV'' 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]].

[[/folder]]

[[folder: Literature ]]

* Drool Rockworm's permanently red-glowing eyes in the ''ChroniclesOfThomasCovenant'' 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.
* The Nazgul in ''TheLordOfTheRings'' are often depicted in art as having glowing red eyes. As they are normally invisible, this is their only visible feature.
* [[TheThrawnTrilogy Grand Admiral Thrawn]] from TimothyZahn's [[StarWarsExpandedUniverse Star Wars spinoff novels]] is a Chiss, a race of aliens closely related to humans but with blue skin and featureless glowing [[RedEyesTakeWarning red eyes]]. 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 [[LightsOffTheirEyes 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 ''{{Discworld}}'' with [-[[TheGrimReaper DEATH]]-], who has glowing ''[[ColorCodedForYourConvenience blue]]'' eyes (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.
* An interesting variation occurs in the 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.''
* Ba'alzamon from ''TheWheelOFTime'' has eyes that occasionally appear to be pits of fire. After he's defeated, his body has its eye sockets burned out.
* In Fiona Patton's ''Branion'' 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.

[[/folder]]

[[folder: Live Action TV ]]

* The Goa'uld from ''{{Stargate SG-1}}'' do this for intimidation, as well as involuntarily when taking on a new host.
** Slightly subverted in the fact that the Tok'ra, the good alien cousins of the Goa'uld, also show off their glowing eyes.
*** Yeah, 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 did this when possessed by the Ori, as did Adria on her own, both before and after ascending.
* Lyta on ''[[BabylonFive Babylon 5]]'' had both a GlowingEyesOfDoom mode when under Vorlon influence and a glossy black eyes mode when resisting (or influenced by) the Shadows.
* Willow on ''BuffyTheVampireSlayer'' gets a pair of completely black eyes when tapping into TheDarkSide, once against Glory for messing with her girlfriend, and the other when she does her FaceHeelTurn following Tara's murder.
** And when she did some serious white magic in the last episode, she gets a pair of completely white glowing eyes.
* Henry Scudder, Justin Crowe, and [[spoiler: Sofie Bojakshiya]] in ''{{Carnivale}}'' all display completely black eyes when channelling their Dark avataric powers.
* The main villain on ''{{Thunderbirds}}'', known as The Hood, has eyes that glow yellow when he uses his mesmeric powers.
* ''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 ''{{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 [[Comicbook/{{X-Men}} 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 ''{{Charmed}}''. For example, Cole's eyes glowing with fire after a YouKillItYouBoughtIt turns him into the BigBad in season four.
* In the ''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.]]
* The Master in the ''DoctorWho'' MadeForTVMovie had constantly glowing yellow eyes which he concealed behind sunglasses and used to instantly hyptonise Chang. It's unknown whether this was a result of his deteriorating body due to imperfect possession, a referrence to the snake form in which he was previously, the continued influence of the Cheetah Planet that gave his ''last'' incarnation EyesOfGold, or the general TheyJustDidntCare atmosphere of the movie.
* Another ''DoctorWho'' example would be Rose when she becomes part-TARDIS, or whatever. When the Doctor takes it out of her, his eyes glow too.
** Ditto Donna when [[spoiler: her Time Lord metacrisis brain kicks in.]]
* Most werewolves on ''Big Wolf On Campus'' have eyes like this. Tommy being the most obvious example.
* When [[MightyMorphinPowerRangers Tommy Oliver]] was BrainwashedAndCrazy, his eyes would occasionally glow neon green.

[[/folder]]

[[folder: Tabletop Games ]]

* In the original ''VampireTheMasquerade'', the single-dot Protean power was Eyes of the Predator (or something like that). 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.
** "Eyes of the Beast" or "Gleam of Red Eyes" depending on the edition.
* Seemingly ''everyone'' in ''{{Warhammer 40000}}'' has these. It can only be assumed that any face-concealing helmet will have [=LEDs=] in the eyepieces.
* Tieflings in the 4th Edition of ''DungeonsAndDragons''. 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 [[EyesOfGold gold]] or [[RedEyesTakeWarning red]].
** In 3rd Edition ''DungeonsAndDragons'', psionic characters would gain glowing eyes whenever they used many of their powers.
**Certain spells such as Arcane sight make a persons eyes glow blue, Darkvision can make a characters eyes flash or glow red.

[[/folder]]

[[folder: Videogames ]]

* Dracula of ''{{Castlevania}}'' fame has glowing [[RedEyesTakeWarning red eyes]] - 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.
* The Heartless of the ''KingdomHearts'' series, at least those with visible eyes, do this constantly. So does Sora in his Anti Form.
* Common in fighting games, especially with possessed or boss characters. Akuma and Evil Ryu from the ''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 ''Street Fighter II''.
* Fighters in ''SuperSmashBros Brawl'' 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/en_us/characters/images/mario/mario_070529a-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...
*** Though what amuses me is that they took the time to actually give Falcon a single, real eye under his helmet, but they didn't make it glow when he got the smash ball.
** Speaking of Brawl, Link and Toon Link both have "dark" alternate costumes featuring ebony skin, white hair and, yes, glowing red eyes.
** Zoom in on Pikachu just as Volt Tackle is being prepped - notice the position of the lips, the shape of the eyes, and the aforementioned glow - and tell this troper that that visage doesn't ''scream'' '''RAPE TIME'''!
* Dahlia Hawthorne from ''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.
* In ''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.
** Which is one of the most fucking awesome things in the game, by the way. This Troper remembers [[CrowningMomentOfAwesome the first time we walked into Oakvale in that form....]]
* In ''KingsQuest VI'', you can recognize a shapeshifting genie, trying to lure you to your death, by his flashing golden eyes (see [[XMen Mystique]], below).
* Subverted with Sparda in ''DevilMayCry'', 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 [[RedEyesTakeWarning red eye]] glows when he TurnsRed.
* In ''{{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 ''Wolfenstein 3D'' - but only on enabling of God Mode (no invincibility powerups in that game).
* ''CityOfHeroes'' has several different forms of these as 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.
** [[{{Argetlahm}} This editor]] favors them heavily in his characters' costumes, whether they are proper GlowingEyesOfDoom or arguably less threatening Glowing Goggles of Doom.
** Also, human-form Kheldians' eyes glow when using their powers as an indication that they're channelling power from their alien halves.
* ''WorldOfWarcraft'' sure loves its glowing eyes. A lot. Lots of races have glowing eyes; in some cases it's just a feature of their species, but in other cases it's more in line with this trope. Examples:
** The Warlock class's demon [[{{SummonMagic}} summons]] have glowing eyes (except the Felhunter, whose eyes are so tiny as to be practically invisible).
** All members of the Draenei race have glowing blue (or white, depending on the artist) eyes. Since the Draenei are good guys ([[LawfulGood almost insufferably so]]), this could count as a subversion of this trope. However, their fellow Eredar who made a DealWithTheDevil to turn into demons have their eyes turn glowing yellow as well as gaining [[{{ColorCodedForYourConvenience}} red skin]], horns, and SpikesOfVillainy.
** Male Night Elves have glowing golden eyes and female Night Elves have glowing silver eyes. The Night Elves [[{{DarkIsNotEvil}} aren't evil per se]], but they are distrustful of other races, are rather prideful, and have made some mistakes in their past.
*** The original cinematic for World of Warcraft shows that a night elf's eyes reflect light like a cat's, not glow. This makes sense, as the night elves live up to their name by living where it's always night. But it would be difficult to show that in the graphics of the real game.
** The Forsaken [[{{TheUndead}} Undead]] have [[GlowingEyelightsOfUndeath glowing golden eyes]]. This fits into this trope nicely, as they are the closest thing [=WoW=] has to an evil player race.
*** Blood elves come pretty close, as well.
** The Blood Elves have glowing green eyes that are a side-effect of their addiction to demonic magic. Before that started, they were High Elves, who just had an addiction to normal magic and had glowing blue eyes.
** Fel Orcs, who achieved their state by drinking a demon's blood, have glowing red eyes.
*** And, for all races, several headpieces (usually tier set headgear) confers glowing eyes, especially Rogue and Warlock sets, but found in the odd Paladin and Hunter sets too.
****The exceedingly odd hunter Tier 6 Gronnstalker set, is ''covered'' in [[NightmareFuel glowing]], '''moving''' eyes. [http://www.wowhead.com/?item=31006] (click on the screenshot).
** Hey, don't forget Arthas!
** Members of the new Death Knight class in the ''Wrath of the Lich King'' ExpansionPack all have glowing blue eyes, regardless of race, due to them being partially undead. Other powerful undead, such as Liches (Lichi? Lichen?) or the special Death Knight only mount, have the same cyan/blue glow. They also have a [[VoiceOfTheLegion creepy reverb]] in their voices.
** Virtually all the epic mounts in the game have glowing eyes, even the common ones that can be purchased. How did all these beasts of burden get these glowing eyes? No one in-universe seems to notice or care.
*** Hey, they used to be the best you could get, at maximum level, of course they would try to look [[RuleOfCool cool]]. Whether it made sense or not, it was obligatory.
* [[TheBerserker Grom Hellscream]] had glowing red eyes in ''{{Warcraft}} III'', 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.
** The [[TheMedic Priests]] of Warcraft III have growing blue eyes as well, and the [[MagicKnight Paladins]] of Warcraft II have glowing yellowish-orange eyes, suggesting that it may a product of the magic of [[TheForce 'The Light']], though spellcasters of the same magic have otherwise not been seen with glowing eyes regularly.
* Continuing from the ''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. This troper's favorite is whenever Char Aznable pilots his Sazabi, which provides a particularly menacing image. Of course, it IS a Zeon MS....
* Sam Fisher of ''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 ''TheLegendofZelda: Ocarina of Time,'' Ganondorf's eyes start glowing hellishly just before he goes into OneWingedAngel mode.
* Those infected by the UnstoppableRage in ''MortalKombat vs. DCUniverse'' have this.
* The four fiends of FFIV seem to have this, whether or not it's due to graphical limitation is debatable.
* In ''{{Overlord}}'', [[PlayerCharacter YOU]] have these.
* ''{{Geneforge}}'', people who use many canisters frequently develop glowing eyes. They're not necessarily evil, but they are [[PowerGlows powerful]] and [[WithGreatPowerComesGreatInsanity frequently unstable]]. It may be [[InvokedTrope intentional]], rather than a random side effect--a character in the first game says glowing eyes are "designed to engender respect."
* The Little Sisters in ''{{Bioshock}}'' have glowing eyes until they're rescued.
* Phazon-corrupted characters in ''[[{{Metroid}} 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.]]
* ''{{Freespace}}'''s Shivans have ''seven'' GlowingEyesOfDoom. [[http://www.nightsolo.net/fs2guide/shivan1.bmp In a V shape.]] All of them are [[RedEyesTakeWarning red]]. As one might surmise, Shivans are [[NightmareFuel scary]].
* The Moon Rabbit, Reisen Udongein Inaba, from ''{{Touhou}}'' has these. She has the ability to drive people [[MindRape insane]] by using her eyes to screw around with wave lengths, with also allows her to make illusions and such. However, while you fight her, a pair of seriously freaky [[NightmareFuel GIANT RED EYES]] appear in the background to signal that she's screwing with you. All the more fun, considering that her last Spell Card turns her attacks invisible.
** Patchouli gets these in TouhouMusouKakyou after [[BerserkButton getting hit in the face with one of her own books]] during an argument by Marisa and Aya while Reimu is trying to interrogate her about her missing donation box. The next shot after a short scene with Sakuya and Remilia is Patchy busting out her Royal Flare spell card.
* The three core characters in ''{{Disgaea}}: Hour of Darkness'' 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.
* Maybe-sorta used in ''[[JakAndDaxter Jak 2]]'' and ''Jak 3''. The Light Jak form has glowing white eyes in a shadowy blue form (plus, in the later stages, [[OurAngelsAreDifferent massive radiant wings]]); the Dark Jak form actually ''inverts'' this, with reflective all-black eyes, like SinisterShades under the skin. While the Dark Jak form is supposed to be more dangerous, being a SuperpoweredEvilSide and all, the Light form is more dangerous, because it can ''freeze time, then blast the hell out of you with [[ThereIsNoKillLikeOverkill the Supernova]]''.
** Only in Jak 3. In Jak 2, Dark Jak reigned supreme. His first power, Dark Bomb, wiped out entire rooms, and his final power is [[AttackOfTheFiftyFootWhatever Dark Giant.]] Between the two he gets Invincibility, and in the third game he gets ''another'' power up. So he can fight at range too. It's a close call between the two forms.
***Technically, Dark Jak has BlackEyesOfEvil.
* The PerversePuppet that [[CreepyChild Lieselotte]] carries around in ''ArcanaHeart'' has these as a side-effect of her dead sister possessing it.
* All of ''{{Persona 4}}'''s shadows have these when in human form.
* In ''{{Killzone}}'', the Helghast combine their [[GasMaskMooks gas masks]] with these.
* Rider in ''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 Medusa. Figure out the 'of doom' part.
* In the opening cutscene of ''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 ''KatamariDamacy'' and all ascending games, when you fail, the King's eyes will glow and make a speech on how much you fail.
* In ''{{Starcraft}}'', all the Protoss (and most of the Zerg) have glowing eyes
* The Kaka clan from ''{{Blazblue}}'' 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, [[KingOfFighters Kim Kaphwan]]'s eyes have been known to become sparkling white spotlights when he decides to start kicking evil in the ass.

* The title race of Tarol Hunt's ''{{Goblins}}'' sport these when angered.
** It's not glow - it's their widened pupils. Big Ears on the other hand did recieve these when he aquired his enchanted paladin gear.
* Magic users in ''DominicDeegan: Oracle For Hire'' have their eyes glow when particularly focused.
* Reynardine from ''GunnerkriggCourt'' 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]] ''{{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!
* Richard from ''LookingForGroup'' has glowing yellow eyes. [[http://www.youtube.com/watch?v=fcbazH6aE2g One could say he fits the trope.]]
**And Maikos too.
* ''OrderOfTheStick'': 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 ''OrderOfTheStick''. [[http://www.giantitp.com/comics/oots0160.html Samantha the Sorceress]] and more recently, [[http://www.giantitp.com/comics/oots0597.html Vaarsuvius]] both glow with an awesome power.
* In ''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).
* In ''CollegeRoomiesFromHell'', Dave's eyes glow when he's about to unleash his laser beams.
* In ''{{The KAMics}}'', 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 Seven Sins of Jack have glowing eyes, the titular character has his eyes grow black and become pin pricks of light when he's ticked off. The Devil subverts the trope by having completely dark black eyes.
* Basilisk class zombies in ''TheZombieHunters'' have glowing red eyes they use to incapacitate prey.
* ''[[EightBitTheatre 8-bit Theater]]'' gives us, at long last, [[HeroicSociopath 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 ''CtrlAltDel'' likes playing [[TheSims Sims 3]]...for a very [[http://www.ctrlaltdel-online.com/comic.php?d=2009-06-01 particular reason]].

* On ''AquaTeenHungerForce'', Frylock's eyes glow blue before he zaps you.
* Aang on ''AvatarTheLastAirbender'' has these when he's in [[UnstoppableRage the Avatar State]].
** Every avatar does this in the Avatar State. However, when its mastered, they only enter it for about half a second (If an Avatar is killed in that state, the cycle will break, so they're vulnerable then) to gather power, then they break out the ass-kicking with normal eyes. Avatar Kyoshi is shown doing this (Eyes pulse, then she earthbends. With ''tectonic plates''.) during the episode, "Avatar Day."
* The titular ''{{Gargoyles}}'' develop these when angered; males have glowing white eyes, while females have glowing red eyes.
** Actually I think it had something to do with alignment...although Demona was the first to show the red eyes, and then Angela, [[spoiler: her daughter]] was next, so maybe it is gender...but I'm pretty sure that in the [[spoiler: first attack on Avalon, the female gargoyles' eyes usually shone white...]]
* ''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.)
* Similarly, although most of the {{Transformers}} in ''BeastWars'' have glowing eyes, Dinobot's normally red eyes shine bright green when he's charging up his EyeBeams.
* ''{{X-Men}}'': Animated Cable's left eye glows white when using his telekinesis (or at dramatically appropriate moments) and red when using his cybernetically enhanced vision.
* Chernobog, the Slavic dark god, in the "Night on Bald Mountain" segment of ''{{Fantasia}}''.
* ''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.
* In ''DannyPhantom'' the titular 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 EyeBeams*
* The titular robot in the ''Ducktales'' episode "Armstrong", when it becomes clear that he's turned on Scrooge.
**I...AM...ARMSTRONG. I...AM...YOUR...''FRIEND.'' [[NightmareFuel Brrrr.]]
* [[{{Disney/Aladdin}} Jafar]] in his genie form has glowing yellow eyes, visible for about two seconds before he gets stuffed in a lamp.
* Mr. Bison from ''StreetFighter: The Animated Series'' while explaining that he does not whine about it!
* A few episodes of ''{{Metalocalypse}}'' end with the band members' eyes glowing red, notably ''Performanceklok'', which ends with them watching their therapist being ripped apart by wolves.
** "Gosh. Maybe this is weird to say, but... am I the only one who's being made to feel hungry by watching... this? "
* Green Lantern John Stewart from ''JusticeLeague'' has glowing green eyes as long as he's wearing his power ring -- WordOfGod says that it's because he's been a GL for so long that it's more or less "infected" him.
* [[TheSecretSaturdays Zak Saturday]]'s eyes glow yellow-orange whenever he uses his cryptid-controlling powers.

* Parrot eyes don't glow, but they do dilate very noticably- "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.
