->''"Huge eyes means good!"''
-->-- ''WebVideo/WeddingPeachAbridged''

In many animated series, goodies and baddies are distinguished by [[BigEyesLittleEyes the size of their eyes]]. TheHero, the AllLovingHero, and the WideEyedIdealist will all have big, open, happy, trustful, PuppyDogEyes. On the other hand, the MagnificentBastard, EvilOverlord and CardCarryingVillain will have narrow, shifty eyes. Might be because large eyes makes the face appear more infantile. See also {{Beauty Equals Goodness}}.

However, this trope is slightly more complex than it used to be. Instead of one eye size for goodies and another for baddies, there is a continuum between the FriendToAllLivingThings and the BigBad reflecting just how good or bad a character is. On the side of good, the {{Badass}} AntiHero willing to ShootTheDog has eyes narrower than the hero's but wider than those of the villain. Villains with wider eyes tend to be of the KnightTemplar, WellIntentionedExtremist, or AntiVillain types; either that, or they will PetTheDog a few times.

In a SliceOfLife series without heroes or villains, narrow eyes are often used to indicate TheCynic.

See also ScaryShinyGlasses. CommonEyeColors are more useful to ascertain personality traits and temperament than moral alignment. Note that characters who have their EyesAlwaysShut do not really fit anywhere on this continuum, as they tend to symbolize something else entirely, whether good or evil. When this trope is used with [[RidiculouslyCuteCritter critters]] or [[AttackOfThe50FootWhatever monsters]], it's BigEyesLittleEyes.

Likely unrelated but interesting nonetheless is the fact that ancient cultures often portrayed spiritual people in their art with gigantic eyes. They apparently believed that wider eyes meant someone was more capable of communicating with their gods.

[[foldercontrol]]

[[folder:Anime & Manga]]
* Played with in ''Anime/CodeGeass'':
** Lelouch Lamperouge, the resident MagnificentBastard AntiHero, who is morally dubious at best, has very wide, beautiful, expressive eyes.
** Played straight with his older brother, Schneizel, who is unmistakeably a villain, and has narrow eyes.
** And again subverted with another AntiHero, Suzaku Kururugi, who is (like Lelouch) morally ambiguous, and yet still has wide, sparkling GreenEyes.
* ''Anime/TenchiMuyo'' is almost a case study in the example of Innocence vs. Cynicism. Compare the eyes of Sasami, Washu, Ryoko, and Mihoshi.
* ''Manga/{{X 1999}}''
** Compare the eyes of AntiHero Kamui to those of AntiVillain Fuuma. Or those of BlindSeer Hinoto to those of her evil sister, Kanoe. Or, indeed, any Dragon of Heaven to any Dragon of Earth.
** Another example: It's easy to tell that [[spoiler:Hinoto]] has gone to the dark side when her eyes appear significantly narrower.
* ''Anime/YuGiOh'': Yami Yugi and [[SuperpoweredEvilSide Yami Bakura]] both have narrower eyes than their hosts. Malik already has narrow eyes, but his superpowered eviller side has even narrower ones.
* Used in, oddly enough, ''Manga/{{Saikano}}''. [[spoiler:Shuji's friend who joins the military]] is a WideEyedIdealist, complete with literal wide eyes. On the other hand, the other soldiers, none of whom have any illusions about the state they'll return home in, all have extremely narrow eyes.
* ''Manga/FullmetalAlchemist'':
** Though Col. Mustang is eventually portrayed in a sympathetic and somewhat heroic light, he initially comes across as a nasty piece of work, and possesses the narrowest eyes of the regular military characters.
** This is especially apparent when Mustang finally [[spoiler: found Envy, and was about to give in to his hatred]]. His eyes almost narrowed to a slit. Ed notices this and says, "Take a good look at your face before you do anything! You think you can lead a country looking like that?!"
** Ling Yao is a subversion. He's at heart a decent guy with a moral code, but his eyes are very narrow and he himself admits they look "shifty". (He's also an Asian in a cast full of Caucasians, so take that how you will.) He tries to mitigate the effect by keeping his EyesAlwaysShut.
*** After [[spoiler:Greed takes over Ling's body, the eyes signify who's in charge. In the manga if the iris is colored in, it's Greed. If the iris isn't colored in (or if his eyes are closed), then it's Ling. In the manga the direction his bangs are pointing also help distinguish the two. In the anime the two are mostly distinguished by their voices, but even then Ling usually keeps his "shifty eyes" shut when he's in control unless he's being serious. Also, when they're open, Ling's pupils tend to look somewhat smaller than Greed's.]]
** The heroic Hohenheim and the BigBad Father look practically identical but for the fact that Hohenheim has much friendlier-looking eyes.
** Solf J. Kimblee, a psychopathic MadBomber has eyes which are reptilian-looking pin pricks.
** The homunculus Pride when he drops the [[spoiler:Selim Bradley]] persona, [[http://images3.wikia.nocookie.net/__cb20100428181413/fma/images/c/c6/Selim_bradley3.jpg especially in]] [[http://images2.wikia.nocookie.net/__cb20100607072550/fma/images/f/ff/PrideFace.jpg the animated adaptation]].
** In the [[Anime/FullmetalAlchemist 2003 anime version]], [[PsychoForHire Col. Archer]] has unrepentantly narrow eyes.
* ''{{Anime/Beyblade}}'': Tyson and Max have wide eyes. Ray and Kai, who both have degrees of AntiHero, have narrower ones.
* In ''{{Manga/Bleach}}'', the heroes have generally big eyes, with [[TheChick Orihime's]] being the biggest. Among Soul Reapers, the greater the KnightTemplar tendency, the narrower the eyes. Well, everyone except for Gin, whose [[EyesAlwaysShut eyes always seem to be closed]] for some reason.
** Also, Aizen. [[spoiler: Starts out good, eyes are wide. Once he reveals that he's evil, his eyes narrow considerably.]]
* ''Manga/DeathNote'':
** [[VillainProtagonist Light]] normally has squinty, narrow eyes, but when he temporarily [[MemoryGambit has his memory erased]] and becomes a good guy, his eyes widen considerably.
*** It is even almost lampshaded; after losing his memory, Light asks L if his eyes look like those of a murderer.
** This happened in a cycle. In the beginning, his eyes were in the wider variety. Then, as time went by and he grew more conniving and duplicitous, they grew narrower (accompanied by an overall harshness to his features).
** On the opposing side of the cat-and-mouse game, L has eyes that, while dull and baggy, are pretty wide and round in contrast to Light's narrow, angular eyes.
* Sort of used in ''Literature/HaruhiSuzumiya''. The series does not have any heroes or villains, but Kyon, being the most cynical character, has considerably narrower eyes than the rest of the cast.
* ''Anime/GunXSword'' subverts it - Van, the hero, has eyes half the size of his companions. It also plays the trope straight to a degree, however; his rival Ray has ''narrower'' eyes. This being a Goro Tanaguchi series, everyone's eyes double in width when they get pissed off, balancing things out.
* Parodied, perhaps inadvertently, in ''Anime/ProjectAKo''. A-Ko's eyes, while wide, do not approach the massive Creator/{{CLAMP}}-influenced orbs of [[TheDitz C-Ko]]. GadgeteerGenius PsychoLesbian B-Ko, of course, has the classic villainess eyes.
** [[TimeParadox CLAMP-influenced...?]]
* ''{{Manga/Naruto}}'' plays this trope to a T. Naruto either has his eyes shut or open wide, fitting with his personality. When his SuperpoweredEvilSide takes over, his eyes narrow.
** The dark outlines around Gaara's eyes make them appear narrower when he is looking menacing, but wider when he is portrayed sympathetically.
** Averted with the first three Hokage. All three of them have very narrow eyes, but are calm and pretty much embody LawfulGood.
* Although [[ImplacableMan Kazuo Kiriyama]]'s eyes in the manga version of ''Literature/BattleRoyale'' are not appreciably smaller than those of the major male protagonists, they do not reflect any light, giving them a flat, empty appearance illustrating the character's complete lack of emotion.
** The same applies to many characters in the ''Manga/BlackLagoon'' manga, most notably Revy.
* In ''{{Manga/Genshiken}}'', while Ogiue is initially full of self-loathing and cynical, her eyes don't reflect light. Later, when she [[CharacterDevelopment begins accepting herself for what she is]] and her cynicism starts to melt, her eyes begin to shine.
* ''Manga/ElfenLied'' makes prolific use of this trope, specifically with Lucy/Nyu, who can either have large, bubbly, innocent eyes in her Nyu persona to signify her innocently ignorant mindset, or narrow, hateful, and tortured eyes (that are [[HiddenEyes hidden]] most of the time) in her Lucy persona to signify her extremely dark, murderous, and tormented mindset. In fact, a key characteristic of a diclonius who's been [[BreakTheCutie pushed too far]] is a piercing, glazed over look in their eyes, signifying their descent into murderous misanthropy (basically every diclonius in the show goes through this at one point or another, given that HumansAreBastards). For some of them this is essentially a permanent state.
* Subverted with ''{{Manga/Kaiji}}'''s titular lead character, whose tire-punching vandalism doesn't make him evil, just a loser.
* ''Anime/TriGun'' uses this quite a bit, especially with Vash, who either puts on his ominous ScaryShinyGlasses or gets a narrow (if not GlowingEyesOfDoom) look in his eyes, Knives, whose pupils dilate disturbingly whenever he's feeling particularly sadistic, and Legato, whose demonically evil eyes (or technically [[HiddenEyes eye]]) are specifically focused on when he makes his opening entrance (in fact, this is one of the reasons why Vash is so terrified of him).
* Used in ''Manga/GetBackers'' especially in regard to [[PsychoForHire Akabane]] whose eyes (which are already extremely narrow) dilate to the point that his pupils look like periods when he is feeling particularly unstable.
* Extremely noticeable in ''Anime/RurouniKenshin''. Not only do all villains have narrow eyes and all the protagonists have wide ones (the wider the eyes, the more optimistic/naïve the character). Kenshin's own eyes go from wide to narrow as he gets closer to falling into his [[SuperpoweredEvilSide Battousai mode]].
** This is also parodied after a fight (in the manga at least) when Kenshin's eyes got stuck in "Battousai mode" and he doesn't go back to normal until his friends mess with his face.
** However, it is also {{lampshade|Hanging}}d and subverted once. When AntiHero [[TheRival rival]] Saito first appears, Sano, TheLancer, goes out of the way to point out his small, "squinty" eyes as a reason for concern. While Saito initially acts as an antagonist, he turns out to be ''even more'' tireless than Kenshin in fighting against the bad guys, living his life by the code of "Slay evil immediately". (Fans seemed to have noticed the trope too, as Kenshin's author made a note of how he received many letters from [[TheShinsengumi Shinsengumi]] fans upset at Saito's villainous look when first introducing him).
** Also subverted with [[TheDragon Soujiro]], who has big, [[{{bishonen}} innocent-looking eyes]].
** The GenreSavvy [[ReligiousBruiser Anji]] [[TheBrute Yukyuzan]] not only has narrow eyes [[spoiler: (unlike in his past, where he had wide idealist ones until being horrifyingly broken)]], but he applies ashes to his eyelids to make them look even smaller and squintier and have even more menacing looks.
* ''Anime/CowboyBebop'': Just compare the eyes of [[http://xfb.xanga.com/451c2a1b33130182112693/w139345007.jpg Spike]] and [[http://x95.xanga.com/732c541bd3630182113348/w139345563.jpg Vicious]], and then guess which is the AntiHero and which is the EvilCounterpart.
** Assuming of course that the [[PropheticName name wasn't enough of a tipoff]].
* While nearly [[HalfIdenticalTwins identical in appearance]], there's a single major physical disparity between ''[[{{Anime/Monster}} Monster's]]'' [[http://static.tvtropes.org/pmwiki/pub/images/monsterjohan.jpg Johan Liebert]] and his twin sister, [[http://static.tvtropes.org/pmwiki/pub/images/nina.jpg Anna]] that tells you which one's the [[EvilTwin evil one]]. You have three seconds to get it right.
** [[ComicallyMissingThePoint Johan would have to stuff his bra and is therefore evil.]]
* Played with in ''Anime/PrincessTutu''. Ahiru, the main heroine, has ''huge'' blue eyes, even when she's in her duck form, showing her innocent, sweet nature. Fakir, a dark, brooding character who's often a jerk, has extremely narrow green eyes. He's the villain, right? [[spoiler:WRONG! Rue--whose eyes are narrower than Ahiru's, but not nearly like Fakir's--turns out to be the DarkMagicalGirl, whose eyes look significantly more narrow when she transforms.]] Also messed with in the second season with Mytho. [[spoiler:Normally his eyes are nearly as wide as Ahiru's, but when his heart is poisoned with Raven's blood and a selfish, evil personality takes him over, his eyes dramatically narrow before our very eyes]].
* Also used often in ''Manga/OnePiece''. Notable is how when Boa Hancock was first introduced, she had narrower eyes, but after [[spoiler: her FreudianExcuse was exposed and she fell for Luffy]] her eyes got bigger. Luffy falls into this trope as well. When he's in a normal state, he's got big, cute, childish eyes. When angered, his eyes narrow considerably, making him look much older. (to add to the effect, his body is drawn to be more defined and adult.)
** Not to mention, his irises are also drawn. [[http://i234.photobucket.com/albums/ee21/yourlocalchef/luffy-madethemcry.jpg The result gives him a gaze that makes this troper wonder, why anyone would dare to fight him...]]
** Also, while (male) ''Manga/OnePiece'' characters generally have very narrow eyes compared to most manga, the good guys are more likely to have big, round eyes than the bad guys.
* In ''Manga/DeadmanWonderland'' there is a GoodEye/CrazyEvilEyes version of this trope. The good-hearted, wide-eyed, main protagonist meets another good-hearted, wide-eyed, sweet girl who desperately wants to escape DW. He falls for her [[spoiler: and soon after is betrayed. She was faking the whole time in order to drop his guard. Once she shows her TrueColors her eyes become beady and wide as opposed to small and narrow.]]
* In yet another example of eyes changing shape after a personality change, [[spoiler:Nia Teppelin]] from ''Anime/TengenToppaGurrenLagann''.
* Subverted in ''{{LightNovel/Toradora}}''; Ryuuji has narrow eyes paired up with a creepy stare, which make everyone but his friends think he's a delinquent, while he's actually a very NiceGuy.
* Played straight and subverted in ''Manga/AnatoliaStory'': Il Vani, Prince Kail's adviser and close friend, has extremely narrow eyes that make him look evil-ish, at the very least. The evil queen, however, has appropriately narrow eyes.
* In ''{{Manga/Hellsing}}'', [[FriendlyNeighborhoodVampires Seras]] is pretty much the only good guy who has wide eyes (she doesn't have the ScaryShinyGlasses either). Curiously, the members of [[StupidJetpackHitler Millenium]] also tend to have wider eyes, though that's probably because they [[CrazyAwesome have so much fun]] with what they do.
** It's also worth remembering that her irises turn red when she goes ax crazy
* This trope is played with quite a bit in ''Manga/TheLawOfUeki.'' Particularly noteworthy is the {{subver|tedTrope}}sion of Ueki and Kobayashi. Both have heavily slanted eyes with very thin irises ([[HellishPupils or no irises at all]]), a style typically used for evil characters or [[HotBlood hot-blooded]] [[AntiHero anti-heroes]]. Yet, one is the justice-loving TechnicalPacifist hero, and the other is his lazy, friendly, and ([[BadassTeacher usually]]) [[ActualPacifist nonviolent]] teacher/mentor.
* Subverted in the manga ''{{Leviathan}}''; see [[http://www.mangafox.com/manga/leviathan/v04/c019/31.html here]]. That's the character with arguably the biggest eyes so far, going "There's not enough killing yet."
* Played with in the case of General Regius from ''Anime/MagicalGirlLyricalNanohaStrikerS'', whose small, beady eyes, [[FatBastard fat frame]], and [[GeneralRipper general temperament]] rang a lot of "obvious villain" alarm bells. Then he turned out to be a WellIntentionedExtremist who had the same goals as the heroes of protecting the little guys, only he had the misfortune of being manipulated like a puppet by the OmniscientCouncilOfVagueness.
* ''Manga/BlackLagoon'' - as time goes on, Rock's eyes gradually get narrower as he becomes more jaded and [[SlidingScaleOfIdealismVersusCynicism cynical]].
* Mayo Mitama in ''Manga/SayonaraZetsubouSensei'' has "mean-looking eyes," causing everyone to misjudge her . . . [[DevilInPlainSight she really is mean]], but everyone is so concerned with not judging by appearances that they think she must be nice.
* ''{{Anime/Noir}}''. The protagonists Mirielle and Kirika, despite both being ruthless hitwomen, have [[BadassAdorable large round eyes]], whereas KnifeNut Chloe has narrow eyes. Later when Kirika starts to come under the influence of Chloe, her MoeMoe eyes become noticeably narrower.
* Ken Ichijouji from ''Anime/DigimonAdventure02'' is a good example. As the evil Digimon Kaiser, he has narrow eyes and small pupils. After his HeelFaceTurn, his eyes become larger and more expressive.
* Played straight with almost everyone in ''Manga/AngelDensetsu'', to the point that the two AxCrazy female leads have nicer eyes as they become nicer. Subverted to hell by the male lead of course.
* In ''Franchise/SailorMoon'', the good Sailor Senshi have huge {{Moe}} eyes, and the more evil people from the Dark Kingdom/Black Moon Circus/insert latest antagonist group here have narrow eyes. This pattern only exists in the first arc. The second arc breaks it up with the narrow-eyed Sailor Pluto. Uranus and Neptune show up in the third arc, and when wide-eyed villains appear in the fourth arc, the pattern effectively dissolves.
* ''Manga/MahouSenseiNegima'' generally does this; the villains have noticeably narrower eyes then the heroes, though there are exceptions; [[spoiler: Chao's]] eyes are round, and Evangeline, while having narrow eyes, [[NobleDemon only thinks]] [[AntiVillain she's a villain]].
** In addition, [[http://www.mangafox.com/manga/mahou_sensei_negima/v04/c028/ Setsuna]] has narrower eyes then the rest of the cast when she's introduced, as Negi briefly suspects her of being a bad guy. [[http://www.mangafox.com/manga/mahou_sensei_negima/v12/c100/8.html Later on in the series]] her eyes are wider.
** Although given recent events, [[spoiler: Chao is likely more of a HeroAntagonist, playing this trope straight after all.]]
** The eye scale is pretty straight if based on "untroubled" and "uncomplicated", with the exceptions being the characters whose facade is good enough to be semi-real. Noteworthy is that even the ''twins'' can be usually identified by their eyes. (Switch it to "Dark Eyes Light Eyes", add in the series' unusual values for "Dark" and "Light", and everybody fits in about perfectly.)
* Played up heavily in ''Manga/LiarGame''. The incredibly gullible (at first) and generous [[MessianicArchetype Nao Kanzaki]] has anime-standard, big googly eyes, whereas the current main antagonist Yokoya has slit eyes so narrow it's sometimes hard to see them at all.
* In ''Manga/DragonBall'', good characters generally have big round eyes and bad ones have narrower ones. If a bad character turns good their eyes usually don't change. In an interesting twist, bad characters' eyes are fully outlined, while good characters only have the outside edges of the eyes outlined. Again, this generally sticks if the character switches sides. Continuing that, when Goku, Gohan or Goten first turn Super Saiyan their eyes adopt the "bad guy" look. Trunks has the bad guy eyes even in his normal state due to him being related to Vegeta.
** Gohan for some reason gets fully outlined eyes after his "Mystic" upgrade and it sticks for the rest of the series.
* This is very noticeable in ''Manga/FistOfTheNorthStar'', especially when characters switch allegiances. For example, when Rei was originally drawn with beady eyes when he was first introduced, since his status as a hero or villain was still very dubious. Once his heroic credentials were established, he was drawn with rounder eyes.
* With the exception of Walker (whose [[EyesAlwaysShut eyes are always closed]], Izaya Orihara has some of the narrowest eyes in ''LightNovel/{{Durarara}}'' (and are also noted to be very [[TsurimeEyes sharp-looking]] in the LightNovels). He is also a [[{{Troll}} giant]] [[ManipulativeBastard fricking]] [[{{Jerkass}} asshole]] and is more or less the series' BigBad.
* ''{{Umi no Yami Tsuki no Kage}}'' is about a pair of twins which acquire psychic powers. One of them turns evil. You can tell by the small, cat-like pupils she suddenly sports.
* In ''Manga/SukebanDeka'' the main villainess pupils usually completely fill out her eyes (because, you know, she's beautiful and this is a shojo manga). But when her pupils narrow down to small little dots you know you should run for your life.
* A variation occurs in ''Manga/WanderingSon''. The resident DeadpanSnarker, Chiba, changes between eye styles occasionally. In earlier volumes her default expression was wide-eyed like everyone else in the manga. After becoming increasingly more depressed and moody, her eye style changed to her apathetic look which both makes her look more mature and is more closed then her original look; it changed midway volume 4, one page she's her normal expression and the next she's the new one. She'll occasionally lap into the former, but typically only when she's ''really'' happy (at times even when she's happy it doesn't change though) or only for a panel or two.
* The eponymous ''Manga/DetectiveConan'' applies this constantly. When he [[OlderThanTheyLook pretends to be a kid]], he's TaremeEyes-- and would switch to TsurimeEyes in {{meitantei}} mode.
* Homura in ''Anime/PuellaMagiMadokaMagica''. Specifically, [[spoiler:in the beginning, she was {{Tareme Eyes}}, fitting [[{{adorkable}} her]] [[CuteClumsyGirl original]] [[ShrinkingViolet personality]]. The [[BreakTheCutie effect]] of the subsequent GroundhogDayLoop-sque MentalTimeTravel culminated into her hiding all things she considered "weak"-- in addition to LettingHerHairDown and [[TheGlassesGottaGo curing her eyes with magic]],]] her eyes turned to TsurimeEyes.
* [[ManipulativeBastard Kaede]] from ''LightNovel/{{Kampfer}}'' usually has innocent looking eyes, but in episode 10, her eyes clearly shift to a more sinister look while trying to manipulate male Natsuru.
* ''Manga/KamichamaKarin'' plays the trope straight, although in this case it's at least partly due to the bad guys being [[AnimationAnatomyAging a few years older]] than the good guys.
* In the anime of LuckyStar, [[BitchInSheepsClothing Akira]] [[NiceCharacterMeanActor Kogami]] has either of these, swtching from wide, {{moe}}, TaremeEyes in her {{Kawaiiko}} persona, to Tsurime Eyes with small irises and bags underneath when she's being her {{jerkass}} self.
* ''Anime/DarkerThanBlack'': When Hei switches from his "real" personality ({{stoic}} {{badass}} PunchclockVillain {{antihero}}) to his SecretIdentity personality ({{adorkable}} NiceGuy), the main difference is a) [[EvilSoundsDeep his voice going up about half an octave]] and b) his eyes getting [[http://media.photobucket.com/image/darker%20than%20black%20li/Gackt4life/darker%2520than%2520black/DTBHei-LiTrial.jpg much, much wider]].
* In ''Manga/KotouraSan'', Haruka's mom Kumiko has evil eyes croseed with DullEyesOfUnhappiness for the entire season. But near the end of the final episode, [[spoiler:when she reconciles with Haruka]], her eyes change into normal ones.
* Urameshi Yusuke from ''Manga/YuYuHakusho'' has big, wide, BrownEyes. His EvilCounterpart Sensui Shinobu has narrow IcyBlueEyes.
* ''Manga/WChange'': Maki Kisaragi has wide, round eyes when in her "main" personality. When she becomes Dark Maki, her eyes become sharp and narrow. [[spoiler:And when she becomes her AxCrazy third personality, her pupils become tiny dots.]]
* ''HadesProjectZeorymer'', [[TheHero Masato]] has a split personality issue. Whenever his violent alter-ego takes over, his eyes change into evil eyes.
[[/folder]]

[[folder:Film]]
* In ''{{Film/Avatar}}'', the Na'vi have ''enormous'' eyes. The avatars' eyes are smaller, but still much larger than a human's.
* In ''Film/TheGoodTheBadAndTheUgly'', [[BlackAndGreyMorality everybody is squinting, all the time]]-- but Creator/LeeVanCleef squints harder than anybody else. He is, of course, the Bad.
** [[Creator/LeeVanCleef Van Cleef]] is supposed to have said, "Being born with a pair of beady eyes was the best thing that ever happened to me."
** Though to complicate matters, Tuco's (Creator/EliWallach's character) look ranges from the determined squint through to the wide eyed amazement, and he is by no means a saint.
* In ''Film/TheLordOfTheRings'', Sméagol/Gollum's pupils dilate to show which personality is in control. Guess who has the narrower pupils.
[[/folder]]

[[folder:Literature]]
* ''Literature/HarryPotter'' - Bellatrix Lestrange has "heavily lidded eyes". Her sister Andromeda Tonks looks a lot like her but has "wider, kinder eyes". Luna Lovegood has wide eyes.
** Likewise, while Hagrid has "bright, beetle-black eyes", Snape's are said to be black and unfathomable, like dark tunnels. And Ginny has big, bright brown eyes.
* In ''Literature/RomanceOfTheThreeKingdoms,'' Liu Bei is introduced in the first chapter with a description that includes these, among other traits. Given how he ends up described, perhaps it's best not to take it all that literally.
* Very possibly inverted in A.L. Phillips's Literature/TheQuestOfTheUnaligned. While the main villain doesn't actually have bigger eyes, his irises have turned jet-black, causing him to appear to have enormous pupils. This is apparently a significant contributor to the fact that he looks AxCrazy (which he is).
[[/folder]]

[[folder:LiveActionTV]]
* In {{Smallville}}, the difference between LexLuthor and [[{{Superman}} Clark Kent]] is not too noticeable, but surprisingly, in [[spoiler:season six, ''Nemesis'']], when Chloe is firmly Clark's most trusted friend and [[TheScrappy Lana]] is morally questionable, a clear comparison is made between Chloe's wide, bright eyes [[spoiler:as she more or less pleads for Clark's life]] and Lana's narrow, dark ones. They could be seen as the representatives of the arch-enemies at this point.
* Possibly subverted by Ben Linus on ''{{Series/Lost}}'', who has done all kinds of nasty things, up to and including murder, but who has big old bug eyes.
** As of season 6 it was revealed he was [[spoiler: actually both, but due to [[TheChewToy many misfortunes, including watching his daughter gunned down]], he's following his own agenda and has pulled a genuine HeelFaceTurn]].
* ''Series/LazyTown'''s Sportacus has a pair of wide, friendly baby-blues that appear almost [[WhatBeautifulEyes photoshopped in their blueness]]. On the other hand, Robbie not only has pale grey eyes, but also sports [[EvilEyebrows highly-arched eyebrows]] and heavy purple eye-shadow to emphasize the fact that he is indeed the villain.
* Inverted in ''{{Series/Merlin}}''. Morgause has ''huge'' BrownEyes but she is a recurring villain.
* Subversion: In ''TheMightyBoosh'', the completely non-evil StraightMan Howard Moon has narrow eyes, though is rather sensitive about them.
* The Doctor in ''Series/DoctorWho'' has been played by a succession of extremely odd-looking blokes, but almost all of whom have had much bigger eyes than average, with the Fourth (Tom Baker) and the Tenth (David Tennant) having exceptionally large and expressive eyes. The exception is the Sixth (Colin Baker), whose eyes are rather small for his face. The Fourth and Tenth are two of the most popular and beloved and the Sixth is one of the least... hmm.
[[/folder]]

[[folder:NewspaperComics]]
* Gary Trudeau specifically mentions in a collection that he drew Barbara Ann "Boopsie" Boopstein's eyes [[http://images.gocomics.com/images/doonesbury/strip/thecast/boopsie2.jpg wide and round]] -- in an intentional contrast to the usual [[http://lh3.ggpht.com/_g7tLzt48He8/Sab9t3U9u5I/AAAAAAAAD0E/e4baoADN1x4/db090226.gif heavy-lidded, half-open]] ''{{ComicStrip/Doonesbury}}'' style -- in order to convey her unique naivety and cheerfulness.
[[/folder]]

[[folder:Video Games]]
* ''KingdomHearts'': Sora and Kairi have big, wide eyes (especially in the first game); AntiHero Riku's are narrower. Nearly all of Organization XIII have narrow eyes. Larxene, however, has eyes so big they rival Sora and Kairi's, and she's perhaps the [[PsychoElectro scariest]] [[KnifeNut member]] of the Org. AxCrazy Vanitas also has large eyes by virtue of being [[spoiler: a Sora look alike]].
* In ''VisualNovel/PhoenixWrightAceAttorney'', one of the most prominent differences between Phoenix and Edgeworth - apart from their clothing and hairstyles - is in their eyes, making the contrast between Phoenix's idealism and Edgeworth's cynicism that much more explicit.
** In Case 1-5, Angel Starr actually has one of each, always [[PeekABangs covering one with her hair]] to show if she's being sweet or bitter. However, this is because she wears colored contacts to deliberately [[InvokedTrope invoking this trope]] to have people trust her or fear her accordingly.
** Same deal with [[spoiler: Matt Engarde]].
** April May, Anita Tiala
* In those times where he appears separately (namely ''[[VisualNovel/{{Tsukihime}} Kagetsu Tohya]]'' and ''VideoGame/MeltyBlood''), [[VisualNovel/{{Tsukihime}} Tohno Shiki]]'s [[SuperpoweredEvilSide Nanaya personality]] has narrower eyes than normal...though it might just be due to his [[PsychoticSmirk default expression]].
* The first ''JakAndDaxter'' videogame gave the (then comparatively innocent) main character and his romantic interest eyes the size of soccer balls. The villains' eyes were substantially smaller. Then, over the sequels, this was expanded upon. When Jak TookALevelInBadass at the beginning of ''JakII'' and turned into an AntiHero with anger issues, his eyes shrank by about 45%. And then there are the glowing white eyes of his Light Jak form and the black pits of Dark Jak...
* [[TheChick Merrill]] in ''VideoGame/DragonAgeII'' has larger eyes than anyone has got a right to. She's also the nicest person on your team.
** This is the main characteristic of all the elves in the game, along with pointy ears. Even the brooding AntiHero Fenris has wider eyes than the humans of the team, even though they are narrower than Merrill's.
* Inverted with Fubuki Shirou of InazumaEleven. Normally he has a sleepy look and gentle personality, so when he gets aggressive in his plays [[spoiler:channeling his deceased twin brother]] his eyes widen and he's... suddenly a lot harder to approach.
** Played straight with Kariya Masaki in ''GO''. [[spoiler:Turns out he's not evil though--just a jerk whenever he feels like it. Plus he's mostly ditched his goody-two-shoes act.]]
* ''Franchise/{{Pokemon}}'' villains traditionally have beady eyes and/or a mean KubrickStare. So in ''VideoGame/PokemonBlackAndWhite'', when the villainous team's leader is this... [[WideEyedIdealist doe-eyed]], [[MotorMouth chatty]] [[KidHero teenager]]... yeah, that's a sign ''something'''s up. [[spoiler: Ultimately played straight: the wide-eyed kid is an unwitting TykeBomb for his beady-eyed father.]]

* In ''Webcomic/{{Jack|DavidHopkins}}'' you can safely determine the status of a character by look of their pupils. Damned souls in Hell have tiny beady pupils, living furries, celestials and those of hell-denizen who became conscious of their sins and are eager to amend for them and escape damnation have normal eyes. Demons have glowing red eyes, Satan has pitch-black eyes and so does Jack when he gets mad.
* In ''Webcomic/GirlGenius'', you can usually tell whether Agatha or Lucrezia is in control. I have yet to determine whether it is mostly by the shape of the eyes or whether it's that plus other mannerisms.
** When Lucrezia is in, she frequently ditches Agatha's glasses (for some reason).. Also, she's usually smirking, whereas Agatha alternates looking like a scared rabbit and looking like an EvilOverlord.
* In ''{{Sinfest}}'', [[http://www.sinfest.net/archive_page.php?comicID=4208 enlightenment enlarges the drones' eyes.]]
* In ''BobAndGeorge'', [[http://www.bobandgeorge.com/archives/000410c the newly awakened Megaman notices]] [[MeaningfulName Dr. Wiley]]'s shifty eyes.

* Disney does this a lot. In most of the DisneyAnimatedCanon, the villains eyes are narrower than the heroes. They also tend not to reflect light, making them appear rather soulless.
* ''WesternAnimation/AvatarTheLastAirbender'': [[MessianicArchetype Aang]] and [[TheLancer Katara]] both have quite large eyes. [[DeadpanSnarker Sokka]] has narrower eyes, but they are still wider than those of [[ManipulativeBastard Azula]], whose eyes in turn look narrower (read: crazier) during her breakdown. Zuko is an interesting case - his narrow eyes indicate a dark character; however, [[GoodScarsEvilScars one is narrower than the other]], indicating moral ambiguity right from the start.
** In book 1 Zuko is pissed off all the time, and his one good eye is contorted in frustration. Later, as his demeanor improves, his face relaxes and the eye looks bigger, whilst his [[GoodScarsEvilScars scar]] becomes overgrown by hair. Also, young Zuko's eyes are larger than Teen Zuko, showing that he inherited more good from his [[MamaBear mother]] than his [[AbusiveParents father's evil.]]
** [[PerkyFemaleMinion Ty Lee's]] colossal eyes seem to indicate that she isn't completely evil, which was finally confirmed in "[[Recap/AvatarTheLastAirbenderTheBoilingRockPart2 The Boiling Rock, Part 2]]". Of course, [[EmotionlessGirl Mai]] has eyes even narrower than Azula's, [[spoiler: and she turned her coat moments earlier]].
* In ''WesternAnimation/TeenTitans'', the relatively naive and innocent Starfire has much larger eyes than her comparatively evil sister Blackfire.
* In ''WesternAnimation/TheSimpsons'', most characters have [[SphereEyes wide, bulging eyes]] - except for [[CorruptCorporateExecutive Mr. Burns]] and [[SerialKiller Sideshow Bob]].
* Inverted in the {{DCAU}} where {{Comicbook/Superman}} has squinty little eyes of just an upper eyebrow and a pupil while LexLuthor has more normal eyes with a white to them. Also ignored in most other cases as eye size seems gender based; all ladies get big eyes no matter how evil they are.
* ''ComicStrip/TheBoondocks'' plays an interesting variation: black people have narrow eyes, white people have wider eyes. Due to its {{Animesque}} style, this makes white girls look like [[GenericCuteness your average anime girl]].
* Early episodes of the first ''{{Transformers}}'' episodes had a robot version of it: The good Autobots had blue eyes, and the evil Decepticons had red eyes. Taking this even further, there was an episode where the good guys were brainwashed into evil. The visual cue? Their eyes turned red.
* ''LucyTheDaughterOfTheDevil'' gives wide eyes to the titular AntiAntiChrist, but narrow eyes to [[{{Satan}} her father]]. Jesus's eyes are wide, and [[spoiler:the nun who [[KnightTemplar tries to kill Lucy]] has narrow eyes.]]
* In ''WesternAnimation/{{Recess}}'', the antagonistic characters have narrower eyes than the protagonists.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' tends to give the good characters the standard big watery eyes while villains tend to get scary (and mostly serpentine) peepers. Even minor "villains" like Trixie and Gilda tend to have less reflections in their eyes. Spike ([[Recap/MyLittlePonyFriendshipIsMagicS2E10SecretOfMyExcess except for one episode]]) averts this, as does [[spoiler:Discord after his HeelFaceTurn]].
** In ''[[Recap/MyLittlePonyFriendshipIsMagicS4E23InspirationManifestation Inspiration Manifestation]]'', when Rarity is succumbing to the influence of the spell, her eyes glow freakish green, and the usually enormous irises shrink. When Spike is showering her with kind words of praise and support, her eyes return to their normal limpid pools of blue.

* Our pupils dilate when we feel friendly and affectionate, and constrict when we feel wary and guarded. Consequently, we consider large pupils a sign of warm heartedness and small ones a sign of hostility.
** Pupil size is entirely controlled by the autonomic nervous system. The effect of mood is real, but much smaller than the far more basic accommodation for light level. It likewise is not as important as the function of the autonomic nervous system. Pupil dilation is a result of the sympathetic division of the autonomic nervous system, the part responsible for fight-or-flight. An aggressor will have dilated pupils, as will someone "wide-eyed with fright." Parasympathetic stimulation, the feed-and-breed side of the autonomic nervous system, causes constriction. Likewise, cocaine and amphetamines cause dilation, which heroin causes constriction. Take a look at the size of the pupil of this young Thai boxer [[http://cdn.c.photoshelter.com/img-get/I0000qR.z6BV7vzg/s/750/45-0604-TH-Mae-Sot-Boxing-0338.jpg here]] for illustration.
** This is inverted for cats: bigger eyes with large pupils are scarier because it indicates either they're looking at prey or they are frightened, slightly narrower eyes with medium sized or smallish pupils show trust and comfort with whomever they're looking at. Really constricted pupils indicates hostility or an aggressor.
* 19th-century women used to put belladonna (aka ''deadly nightshade'') extract in their eyes to dilate the pupils, so they would look prettier.
** This is less crazy than it sounds. The key here is that the poison is in the dose or, in this case, the route. The deadly in deadly nightshade comes from atropine (as it's scientific name ''Atropa belladona'' suggests). Atropine blocks pretty much the entire parasympathetic nervous system, which is the calm, feed-and-breed side of autonomic regulation. The PS system causes the pupils to constrict, so atropine (and deadly nightshade) would dilate the pupil. Used low dose topically in the eye, it doesn't really affect the rest of the body, and ophthalmologists used to use atropine for many years for some forms of glaucoma (rare today). Atropine has a few uses in emergencies (nerve gas and pesticide exposure, some heart conditions). Taken ''systemically'', deadly nightshade can live up to its name, especially before we had drugs which could counter its effects.
