28An easy way to tell a villainous (or sinister) character apart from the protagonists, other than giving them a RedRightHand, is making their eyes red. If they don't start out evil, there's a chance they become so over time or perform full-blown FaceHeelTurn. It's not the same thing as the "red eye" phenomenon in photos, but if cameras could [[EvilDetectingDog detect evil]], or danger these would be the first people they'd catch.
29
30Even those who aren't truly evil or dangerous are often thought to be so by characters InUniverse.
31
32In the progressive algorithm of UhOhEyes we have:
33
34SupernaturalGoldEyes < Red Eyes, Take Warning < HellishPupils < GlowingEyesOfDoom
35
36Those with [[GlowingEyesOfDoom glowing red eyes]] are almost without exception thoroughly evil or, at least, on a RoaringRampageOfRevenge or filled with UnstoppableRage. The "almost" section goes to those whose red eyes serve as a marker for their ElementalPowers, since FireIsRed typically or they’re PlayingWithFire. Albino characters with red eyes may suffer from this association with evil; see AlbinosAreFreaks.
37
38If the character can control others and brings their red eye color with them, it may then overlap with EyeDentityGiveaway.
39
40A subtrope of TechnicolorEyes. Compare GlamourFailure, RedIsViolent, CreepyBlueEyes. Contrast RedIsHeroic. Sometimes a part of BurningWithAnger, and thus a harbinger of wrath from the SevenDeadlySins wrath.
41
42'''It should be noted that this trope is NOT just for characters who have eyes of this color, but when the color actually indicates the character is evil or dangerous, or has the FaceOfAThug because of their eye color. Please do not add characters who just happen to have eyes of this color without the proper reason behind it.'''

63[[folder:Asian Animation]]
64* ''Animation/BoBoiBoy'':
65** When [[ShockAndAwe BoBoiBoy Lightning]] is brought to his RageBreakingPoint, he unlocks his NextTierPowerUp, [=BoBoiBoy=] Thunderstorm, who casts a sudden, piercing red glare upon the villains when he's brought out. Thunderstorm is easily one of [=BoBoiBoy=]'s most fearsome forms, with his sheer speed, power and ruthlessness.
66** Season 2 introduces Fang as the main cast's relatively new classmate, who has red eyes and glasses which appear to have a red glowing tint in the dark. He's aloof, arrogant and has a power band like each of the main characters, and the one who provides such power sources, Ochobot, faints at the sight of him. This makes the heroes wary of him, and it doesn't help that Fang sees [=BoBoiBoy=] as an obstacle to his quest for popularity, which has led him to team up with the heroes' enemies at times. It's {{subverted}} later on, however, as he eventually befriends the heroes and proves to be well-meaning. However, his red eyes do foreshadow that [[spoiler:he's not [[HumanAlien exactly human]]]].
67** [[PlayingWithFire BoBoiBoy Fire]] has crimson irises with yellow rings (and sometimes he has FireballEyeballs), and he tends to be a violent MoodSwinger who is very destructive when angry.
68* ''Animation/BoonieBears'': In Season 2 episode 10, those who are within hearing range of the magic flute when it's played on the sun setting become violently aggressive, with their eyes turning red to indicate this.

72* In the ''Animation/SimpleSamosa'' episode "Sumo Momo", when Samosa is fighting Sumo Momo and finally snaps from him breaking the tip on his head, his pupils go red as he gives him a NoHoldsBarredBeatdown.
73[[/folder]]
74
75[[folder:Comic Strips]]
76* These aren't a constant for any character in ''ComicStrip/{{Candorville}}'', but [[spoiler:most vampires]] can activate and deactivate them at will. The only exception so far is [[spoiler:Saxon]], who gets [[spoiler:MilkyWhiteEyes]] either because of his [[spoiler:{{Dhampyr}}]] status or because he's a [[spoiler:FriendlyNeighborhoodVampire]].
77* ''ComicStrip/{{Garfield}}'':
78** The art style usually doesn't allow for eye colors at all, but the infamous "abandoned house" sequence (beginning [[http://www.gocomics.com/garfield/1989/10/23/ here]]) has a close-up of one of Garfield's eyes in [[https://www.gocomics.com/garfield/1989/10/28 the final strip]], red like blood, with the pupil contorted into a spiral as he refuses to accept what he sees.
79** In another very early strip around Halloween, Garfield explains that around that time cats become bewitched. His eyes began to turn red among other things... that is until he saw himself in the mirror, screamed turned white and passed out.
80* Al Capp's ''ComicStrip/LilAbner'' strip had the Nogoodniks, which were the evil version of the Shmoos. They were a sickly shade of green and had "li'l red eyes". They devoured "good" Shmoos, were the sworn enemies of "hoomanity," and wreaked havoc on Dogpatch.

83[[folder:Fan Works]]
84!!General
85* {{Fan Vid}}s and fanart that present Elsa from ''WesternAnimation/{{Frozen|2013}}'' as evil or generally violent very frequently give her red eyes, rather than her normal IcyBlueEyes. GlowingEyesOfDoom are a common alternative but red eyes are used more.

The remastered version switches his eye colour to permanently claret red, like spilled blood, just to amplify the sinister vibe.

178* ''Fanfic/DungeonKeeperAmi'' features this prominently. Keepers all have red, glowing eyes due to the dark magic of their Dungeon Hearts, and they glow brighter when feeling strong emotions, such as anger. This actually becomes a plot point once Ami makes contact with her own world, and is the basis of [[spoiler:Tiger's rather DudeNotFunny annoying prank]].

Played straight in that Voldemort (also known as Vlodemort, Vloxemort and other variations), the BigBad of the story, is frequently described as having red eyes.
185* ''Webcomic/ScoobAndShag'': Unlike other characters' white effects, Number One's eyes and MagicalEyeStreamers glow red when he uses his powers. The glow from his eyes is strong enough to actually light up parts of the scene in episode #74.

186* In the Fanfic/{{Cinderjuice}} story ''"Sleeping Beetle"'', ArcVillain Vasile is described as having "malevolent red eyes." Vasile, a member of the OurVampiresAreDifferent ''strigoi mort'', which, according to vampiric lore do have red eyes.

236** [[EvilChef Chef]] has red eyes, and is the villain of the first movie.
237** ''WesternAnimation/TrollsWorldTour'' has a downplayed case. [[BigBad Queen Barb]] has red irises, and anyone enslaved by her MindControlMusic has their eyes turn completely red, but Barb herself is actually more of a WellIntentionedExtremist, and the red color is rather used to represent the Rock Trolls.
238* In ''WesternAnimation/TurningRed'', whenever Mei is angry in panda mode, her eyes turn red. When not angry, her eyes are their usual brown.
239* [[FauxAffablyEvil Lord Kuruku]] from ''Anime/UnicoInTheIslandOfMagic'' has red eyes.

241
242[[folder:Manhua]]
243* [[CuteMonsterGirl Lilo I]], and probably every other vampire, in ''Manhua/BloodlineTheLastRoyalVampire'' gets this once they drink someone's blood. This gives the showing that she's about to kick ass. M
244[[/folder]]
245
246[[folder:Manhwa]]
247* In ''Webcomic/{{Crepuscule}}'', having red eyes automatically makes you a vampire (though not all vampires are violent). The main character Lark proves an exception to the rule.
248* ''Manhwa/{{Yureka}}'': Player Killers have this. It's a little warning that those players would love to beat the other characters dead
249** Every time you kill a player in Lost Saga you renew your red eyes for another hour. In "The Land of the Dragons", a place where player killers call home, if you ''don't'' have red eyes, you are considered an abnormality. If you're abnormal, you should probably be beat to death.
250** Lotto's eyes, normally brown, tend to show glints of red in color pages when he's feeling particularly murderous.
251[[/folder]]
252
253[[folder:Music]]
254* Music/DavidBowie's "Cat People (Putting Out Fire)", written for [[Film/CatPeople the 1982 film]] and re-recorded on ''Music/LetsDance'', has a lovelorn man singing to an object of desire, warning her of the intensity of his need. The first verse establishes that his eyes are usually green, but they become red in the second verse:
255--> ''"See these eyes so red\
256Red like jungle burning bright\
257Those who feel me near\
258Pull the blinds and change their minds."''
259* The ''Music/PutinP'' series features the Music/{{Vocaloid}} Rin as its main character, whose eyes turn red when she reverts to Red Rin, a dangerous and {{Yandere}} part of her programming [[spoiler:that's actually resultant of a virus inserted into her]]. Camui Gackpo, contrary to his official design, also sports these, and attempts to kill Rin in his introduction. Len remarks on it during their showdown.
260* Music/TheSweet's "Ballroom Blitz" mentions this about the man in the back. "As a matter of fact, his eyes are as red as the sun." He's responsible for it turning into the titular ballroom blitz.
261[[/folder]]
262
263[[folder:Music Videos]]
264* Music/{{Gorillaz}} bassist and MagnificentBastard Murdoc Niccals used to have one red eye and one black eye. The red eye appears to have turned black in recent pics, which may mean anything or nothing story-wise.
265* In [[WebAnimation/MysterySkullsAnimated the animated video for Mystery Skulls' "Ghost"]], [[TeamPet Mystery]] has red eyes. It simply appears to be because of his ColorMotif being red at first, but later on [[spoiler:he's heavily implied to be a [[AsianFoxSpirit Kitsune]], and far more in the know than you'd expect. When this is revealed, his eyes [[GlowingEyesOfDoom glow red]]]].
266[[/folder]]
267
268[[folder:Mythology & Religion]]
269* The eyes of cemetery statue "Black Aggie" are said to glow bright red in the middle of the night, either blinding or killing anyone who looks into them ([[http://www.snopes.com/horrors/ghosts/agnes.asp source]]).
270* One {{Urban Legend|s}}[=/=]CreepyPasta talks about a man who stays at a hotel but is told to stay away from a certain room. Out of curiosity, he peeps through a keyhole and sees an apparently normal room, with a woman sitting against a wall. When she moves, he backs away and returns to his room. Later, he tries looking in again, but he can only see something red through the keyhole. Not able to stand the questions any longer, he asks the hotel clerk what's wrong with the room. She tells him that, years ago, a couple died inside, and they tended not to mention it to avoid upsetting guests. [[spoiler:She also mentions that the couple had unusually red eyes]].
271* The UrbanLegends creature known as [[http://en.wikipedia.org/wiki/Mothman Mothman]] is said to have glowing red eyes.
272* Most people associate red eyes with DemonicPossession and TheDevil.
273* Many Inuit legends feature the [[https://en.wikipedia.org/wiki/Ijiraq ijiraq]], a shape-shifting creature that kidnaps children. No matter what shape an ijiraq shifts into, its eyes will always appear red.
274[[/folder]]
275
276[[folder:Pinball]]
277* ''Pinball/AvengersInfinityQuest'': Getting a tilt warning displays an image of ComicBook/{{Thanos}} with glowing red eyes, tying into his role as the game's BigBad while also visually dissuading the player from playing rough with the machine.
278* The antagonist in ''Pinball/{{Centaur}}'' has small red eyes, as if his bestial face, inhuman form, and dominatrix-inspired design didn't raise enough warning flags.
279* ''Pinball/FooFighters2023'': The Overlord, a megalomaniac alien and the game's BigBad, has red eyes. [[spoiler:It turns out to be part of his mask by the end of the WizardMode -- his actual eyes are completely black.]]
280* In ''Pinball/{{Krull}},'' [[BigBad The Beast's]] red glowing eyes can be seen o both the backglass and the lower-level playfield.
281* Similarly, the monstrous ''Pinball/{{Varkon}}'' has round red eyes, which combine with his small fangs and rounded, brutish face to complete his MonstrousHumanoid appearance.
282[[/folder]]
283
284[[folder:Professional Wrestling]]
285* Ojo Diabolico Jr's ThirdEye has a red pupil. His XMW TagTeam partner Ludark Shaitan {{invoke|dtrope}}s this trope by painting pink circles around her eyes.
286[[/folder]]
287
288[[folder:Theatre]]
289* ''Theatre/CharlieAndTheChocolateFactory'': In the 2017 Broadway retool, the squirrels' eyes glow yellow at first, but then glow red as they [[spoiler: tear Veruca apart]].
290[[/folder]]
291
292[[folder:Theme Parks]]
293* ''Ride/TheHauntedMansion'': In Phantom Manor (the Paris incarnation), the Phantom's eyes glow red at passing riders both times that you pass up close to him (after leaving the Bride's Boudoir, and when leaving Phantom Canyon).
294[[/folder]]
295
296[[folder:Toys]]
297* Zigzagged throughout ''Toys/{{Bionicle}}'', as the eye colors of the characters are all over the place, especially in the earlier years, though there are few straight/inverted cases:
298** Naturally, the original BigBad, Makuta Teridax, also had his trademark red eyes (which he liked to project into shadowy corners), (though in his original set form he had blue eyes with red sclerae),as did many of his brethren, as well as some other villains in the toyline (Krekka, Sidorak, Piraka, Keelerak spiders, etc.). Some, however, eventually substituted orange for red, when the eye colors became ColourCodedForYourConvenience.
299** In the movie ''Bionicle: Web of Shadows,'' Toa Vakama inverts this: he has red eyes ''until'' he goes over to TheDarkSide, at which point, his eyes turn [[SicklyGreenGlow green]]. His toy, on the other hand, always had green eyes.
300** The evil Roodaka from the same movie had blue eyes normally, but when she got really angry, they turned bright orange/red.
301** When Teridax [[spoiler:[[HijackingCthulhu hijacks Mata Nui's body]], his eyes go from yellow to red]].
302* Franchise/{{Lego}} ''Toys/{{Aquazone}}'': The villainous Stingrays have red eyes, among other inhuman traits due to being mutants.
303[[/folder]]
304
305[[folder:Visual Novels]]
306%%* [[spoiler:Shih-na]] has these in ''VisualNovel/AceAttorneyInvestigationsMilesEdgeworth''.
307%%** [[spoiler:Matt Engarde]] in ''VisualNovel/PhoenixWrightAceAttorneyJusticeForAll'' has them too.
308* In ''VisualNovel/CodeRealize'', glowing red eyes are a sign that the person in question is under the influence of Hidden Strength, a process which uses physical and emotional torture to unlock [[PowerBornOfMadness greatly enhanced physical abilities]] and leave them BrainwashedAndCrazy.
309* ''Franchise/{{Danganronpa}}'':
310** ''VisualNovel/DanganronpaTriggerHappyHavoc'':
311*** [[spoiler:Celestia Ludenberg]] fits this trope, since while they seem helpful and sweet in the beginning of the game, eventually [[spoiler:she ends up responsible for two murders, and showed no mercy for it unlike the previous two murderers]]. Of course, even before that, [[spoiler:she was pretty cutthroat and has always been a good liar]].
312*** Kiyotaka Ishimaru technically fits - even though he never makes a FaceHeelTurn, his red eyes are a predicator for [[spoiler:when he ([[MaybeMagicMaybeMundane possibly]]) absorbs Mondo's spirit and becomes the loud and aggressive Kiyondo Ishida — although even then it's a bit of a fake-out, as despite his more aggressive mode of speech he's just as harmless as Ishida as he was before. Unfortunately — and perhaps partially thanks to this trope — it's enough along with Celeste's manipulation to convince Hifumi that he needs to be put down for the good of the group.]]
313** From ''VisualNovel/Danganronpa2GoodbyeDespair'', Peko Pekoyama, the Ultimate Swordswoman has a very noticeable bright red color to her eyes. She's also something of a PerpetualFrowner [[spoiler:and yes she is a dangerous individual, being a hitman for the Kuzuryu Clan of {{yakuza}}]].
314** In ''VisualNovel/DanganronpaV3KillingHarmony'', Maki Harukawa is an uncooperative and [[BrutalHonesty brutally honest]] girl [[spoiler:who's actually the Ultimate Assassin]]. Gonta Gokuhara, on the other hand, has red eyes and is a GentleGiant ([[BerserkButton unless people insult bugs]]), but [[spoiler:he ends up being manipulated into committing murder to MercyKill his classmates]].
315* Wilhelm from ''VisualNovel/DiesIrae'' is perhaps one of the most depraved villains in the story, and being an albino, he has bright red eyes. And the more and more he get's into a fight, the more his eyes start to glow and and take on BlackEyesOfCrazy on top of it. This is especially noticeable when compared with the other albino of the cast, Claudia, who have golden eyes instead and is kindhearted to a fault.
316* The dragonslayer's armor in ''VisualNovel/DraKoi'' has glowing red eyes, suitable for its role as the sort-of antagonist.
317* Solidly averted in ''VisualNovel/KatawaShoujo'' with Akira Satou, Lilly's easygoing CoolBigSis. Well, there ''is'' the fact that she's quite happy to [[FelonyMisdemeanor supply Hisao, Lilly and Hanako, who are minors, with alcohol.]]
318* ''Franchise/{{Nasuverse}}'': A number of characters in the franchise have red eyes, and while it's rarely commented on in-story, a common thread is that all red eyed characters are supernaturally powerful in some manner. Characters like Gilgamesh or Cu Chulainn have divine blood, and their red eyes are an indicator of that. Vampires of all types have red eyes, and people turned into vampires will gain red eyes. Illya is [[OurHomunculiAreDifferent a homunculus]] with tremendous magic power. In short, the red eyes do not indicate a character's morality, but anybody who does have red eyes is generally not someone you want to mess with.
319* The vampires in ''VisualNovel/ShallWeDateBloodInRoses'' have this happen to them when they're about to drink a person's blood. If the vampire has made someone their belonging, their eyes will also turn red when they command the belonging to do something.
320* The key art for ''VisualNovel/SpiritHunterNG'' features the protagonist with a single, glowing red eye. This shows up once in the game; in the Bad End [[spoiler:where he's been transformed into a bloodthirsty monster]].
321* Inverted in ''VisualNovel/{{Suika}}''. Shinigami have red eyes, but are exclusively the kindest and gentlest people who have died.
322* ''VisualNovel/TrappedWithJester'': The only apparent orbs in Jester's eyes are red ones, which tend to show up with a sinister smile. When they appear, expect the screen to darken a bit. That is, unless he says you bore him, and he leaves you to die.
323* In ''VisualNovel/UminekoWhenTheyCry'', the Stakes of Purgatory always wear these eyes. Considering that they are [[BigBad Beatrice's]] ''[[QuirkyMinibossSquad furniture]]'', one can guess what happens when they're around...
324* For a brief moment in ''VisualNovel/FaultMilestoneOne'', [[spoiler: Rune has them as Ritona investigates the graveyard]]. While this was intended to make [[spoiler: Rune appear more sinister than she actually was for that particular scene, it also foreshadowed the reveal that she was an automaton]].
325[[/folder]]
326
327[[folder:Web Animation]]
328* ''WebAnimation/AstroLOLogy'': The [[BewareTheNiceOnes usually nice]] Cancer will have her eyes go fully red whenever she gets angry at the other characters, though the other characters will have angry red eyes as well on occasion.
329* ''WebAnimation/{{Curses|Chrisrin}}'': Every player inflicted with [[{{Geas}} the Boogeyman curse]] is given red eyes; since Etho already has one red eye by default, this is instead changed to his ''non-red'' eye turning red.
330* This trope gets a LampshadeHanging in ''WebAnimation/DeathBattle'' when discussing the Robot Masters during the analysis section of [[Franchise/MegaMan Wily]] vs [[Franchise/SonicTheHedgehog Eggman]].
331-->'''Boomstick:''' [[VideoGame/MegaMan2 Metal Man]] was specifically made for killing things. You could tell, 'cause he's got evil red eyes.
332* ''WebAnimation/{{Dreamscape}}'': Snowball, when in his [[BearsAreBadNews adult bear form]], gets red eyes.
333* ''WebAnimation/DSBTInsaniT'':
334** To show that [[EvilDoppelganger ???]] is evil, its the only thing that seperates him from Koden. Killdra even thinks he's just Koden high on drugs at first.
335** The Darkness counterparts all have red eyes.
336* The title character of ''WebAnimation/FatherTucker'' had his eyes turn red whenever he got angry, which was usually when he threatened the children he molested into keeping quiet about his actions by claiming they'd go to Hell if they squealed on him.
337* ''WebAnimation/{{Glitchtale}}'': [[spoiler: After Asriel's SOUL is eaten by Kumu, Frisk is enraged to the point where their Level of Violence is immediately increased to 19, causing their eyes to open. Their eyes are glowing red as a result of their intense DETERMINATION]].
338* ''WebAnimation/LoboWebseries'':
339** The titular character is a violent bounty hunter with red eyes and no pupils.
340** The [=MBA=] are a race of ravenous alien zombies who have red eyes.
341* Maxwell Edison, in an almost disturbingly well-done Flash video of The Beatles' "Maxwell's Silver Hammer", is depicted with red eyes.
342* ''WebAnimation/TheMostEpicStoryEverToldInAllOfHumanHistory'': Ridiculously Epic, Epic Robot Guy, and Ridiculously Epic Fail all have red eyes and appear to be evil. Ridiculously Epic is [[MoralEventHorizon outright confirmed to be evil]] when he [[DetonationMoon destroys the moon]] and [[StarKilling the sun]] at the end of the trailer.
343* On the website Scratch, user WebAnimation/Qem95 does this on his "Thank you for 300 projects!" animation in order to make the [[ScreamerPrank screamer he pulls off on the viewer]] scarier.
344* ''WebAnimation/{{RWBY}}'':
345** Yang typically has light purple eyes. However, should she get angry and start powering up her [[SuperMode Semblance]], her eyes turn red and flames burst forth from her golden hair. Characters in-universe learn to recognize very quickly what her eye colour change means and to either try to calm the situation down or go into battle mode themselves.
346** The camera has a tendency to zoom in on Emerald's vivid red eyes whenever she's tapping into her mind control powers, which bodes ill for the target of her power. She can [[MasterOfIllusion make a target perceive]] anything she wants, and all the senses are fooled, not just sight. [[spoiler:Emerald's abilities are the main reason why Cinder is so successful in destroying Beacon Academy and becoming the next Fall Maiden. She enables Amber to be ambushed by making Amber think there's a crying child in need of help, and ensures Amber has troubling seeing exactly where Cinder, Mercury and herself are during their fight even when looking straight at them. She also fools Yang into seeing and hearing Mercury attack her from behind after their tournament ends, resulting in Yang appearing to the watching world as though she's attacked a badly injured and defeated Mercury for absolutely no reason. This disqualifies Team RWBY from the tournament.]]
347** The BigBad [[Characters/RWBYSalem Salem]] has eyes that are black pits with glowing red irises and elliptical pupils. They glow malevolently whenever they are feeling sadistic, asserting their dominance or revelling in the plans they have unfolding across the globe. [[spoiler:Salem's eyes are similar to the glowing red eyes of the Grimm, and combines with her bone-white skin, red vein-like markings and black clothing to give her the appearance of a humanoid Grimm. Along with her ability to control the Grimm, this helps make it ambiguous as to whether she's human or something else until her backstory is revealed in Volume 6.]]
348* Ceriazibus from the ''WebAnimation/SockSeries'' has red eyes and is one of Sock's most dangerous monsters.
349* [[WebAnimation/Supermarioglitchy4sSuperMario64Bloopers SMG4]]:
350** [[KnightOfCerebus Zero]] has a single glowing red eye with [[HellishPupils a slashed 0 as a pupil]], and has wiped out countless universes in the past.
351** Melony’s human form possesses red eyes, and she wields the powers of the [[VideoGame/TheLegendOfZeldaMajorasMask Fierce Deity]].
352* In Daria Cohens WebAnimation/TheVampair Series not only do the vampires have glowing red eyes but so does the evil magic cane.
353[[/folder]]
354
355[[folder:Web Original]]
356* The superhero guide ''Blog/HowToHero'' lists red eyes as a surefire indicator that someone is an evil clone.
357* ''Website/NobodyHere'': You can give red eyes to the creepy girl's face in "[[https://nobodyhere.com/justme/present.here Present]]", if you so desire. More pressingly, [[spoiler:she will always have glowing red eyes during the JumpScare]].
358* ''Website/SCPFoundation'':
359** [[http://www.scp-wiki.net/scp-1049 SCP-1049 ("The Bonetaker Owl")]]. SCP-1049 is an owl that can suck a person's skeleton out of their body by biting them. It has red eyes.
360** [[http://www.scp-wiki.net/scp-1111 SCP-1111 ("The White Dog")]]. The title ghostly animal has red eyes that glow more brightly the closer it is to its point of origin. It savagely attacks all human beings that approach it.
361** [[http://www.scp-wiki.net/scp-1461 SCP-1461 ("House of the Worm")]]. In the accompanying story ''[[http://www.scp-wiki.net/the-worm The Worm]]'', exposure to the evil in the house changed some of the human workers into monsters with shining red eyes.
362** [[http://www.scp-wiki.net/scp-1819 SCP-1819 ("Darkness is Only Skin Deep")]]. The boogeyman that inflicts the dangerous SCP-1819 effect on children is described by the children as having a large "bright" or "burning" red eye.
363** [[http://www.scp-wiki.net/scp-2901 SCP-2901 ("Mothman")]]. SCP-2901's standard manifestation is a humanoid with dark-colored wings and large red eyes. They are known to attack human beings, especially when the humans flee them, and their touch causes the victim's skin to be ripped off. They also appear near the sites of disasters and eat the bodies of the victims.
364%%* In ''Literature/VoidDomain'', Arachne has eight of these.

369* [[spoiler:Oswald Sherzikien]]'s eyes turn red when he [[spoiler:[[OneWingedAngel becomes a gigantic cartoon monster]]]] near the end of ''[[WebVideo/TheCartoonMan Journey of the Cartoon Man]]''.
370* Zigzagged in ''WebVideo/CriticalRole''. Mollymauk's eyes are entirely red, lacking both a pupil and an iris. This in itself doesn't actually mean much; Molly's red eyes are due to his tiefling heritage, and while he can be abrasive, he is a genuinely nice person. What ''is'' strange are the nine red eye tattoos placed randomly across his body, especially since Molly himself [[AmnesiacHero woke up with complete amnesia]] about two years prior to the start of the story and has no idea where they came from. [[spoiler:It's not until the final arc of the story, months after Mollymauk's death, that the Mighty Nein encounter [[BigBad Lucien]], the person Molly was before losing his memory. Unlike Molly, Lucien knows that the red eye tattoos are gifts of the [[EldritchAbomination Somnovem]], and can use them to ''devastating'' effect; summoning fireballs, creating an anti-magic field, and unleashing a psychic assault that nearly {{One Hit Kill}}s Beau and Caduceus.]]
371* ''WebVideo/{{Dad}}'': In "Dad Loves Mom", it's mentioned that when Mom is upset, "her eyes glow red"; [[spoiler:with the implication that the family aren't even human, it's likely this isn't just figurative.]]
372* ''WebVideo/EmpiresSMP'':
373** In Season 1, the main antagonist, Xornoth, had red eyes before [[spoiler:the release of the Ender Dragon]]. Similarly, while allied with Xornoth, Joey and Sausage's eyes turn from green and blue (respectively) to crimson.
374** In Season 2, Jimmy's "[[https://namemc.com/skin/eb9e68bcbcc96546 villain arc]]" appearance comes with crimson eyes, but it's {{subverted|Trope}} in that he [[IneffectualSympatheticVillain isn't very good at that]] either.
375* In Heat vs Repulsion video, when heat was pissed off. Cue [[ThemeMusicPowerUp epic music]]. Watch it [[https://www.youtube.com/watch?v=ekz-FY_MDGA here]]
376* ''WebVideo/LogansTale'': Raiders in the [[VideoGame/Fallout3 Capital Wasteland]] often have red eyes. Logan speculates that it's an effect of the chems they take.
377* In ''WebVideo/MicrosoftSamReadsFunnyWindowsErrors'', when ever Sam is seen with red eyes, it's not a good sign.
378* In ''WebVideo/MinecraftDiaries'', Shadow Knights possess these in only their Shadow Knight forms if they have yet to gain their immortality, and all the time if they have done so. (At least, in most cases).
379* PlayedForLaughs when WebVideo/TheNostalgiaChick reviewed ''WesternAnimation/MyLittlePonyTheMovie1986'': a certain pony had red eyes for no apparent reason. Every time she came on screen ominous music would start playing and the Chick would freak out.
380-->''"And what's with your demon eyes?!"''
381* ''Series/TheWeather'': At the end of ''Film/TheWizardOfOz'' segment, Alan, revealed to be a murderer and manipulator, talks to Toto -- who is the only caller with red eyes rather than white, along with a deep voice. They've apparently been the one to convince Alan that everyone else is crazy, and it's implied that this is more-or-less a crazy Alan thinking he's talking to a demon dog.
