[[caption-width-right:345:Does he ''ever'' stop smiling? [[note]] At least he [[EyesAlwaysShut opened his eyes]] once[[/note]]]]

->''"Koizumi's cheerful smile pisses me off every time I see it."''
-->-- '''[[FirstPersonSmartass Kyon's narration]]''', ''[[LightNovel/HaruhiSuzumiya Remote Island Syndrome]]''

The exact opposite of PerpetualFrowner. This is a character who, no matter what, is never seen without a smile of some kind.

A StepfordSmiler would be a sub-trope, one who smiles because that's all they can do to keep from ''breaking''. A CatSmile or CheshireCatGrin can also be their perpetual expression. A rarely explored RealityEnsues version would depict a character with a lot of saliva in their mouth, because it's honestly impossible (or very hard) to swallow one's own saliva while literally always smiling, making even a genuinely sweet smile go from sweet and charming to [[AccidentalNightmareFuel potentially terrifying]] or at the very least disgusting. A Perpetual Smiler's smile can change, and the emotions behind it can be literally anything, so long as there is something that can be called a 'smile' on their face. Usually, though, this smile is pleasant and cheerful, or at least calm, and often, the feeling behind it is genuine, so TheUnsmile doesn't usually appear. Compare to GlasgowGrin, where the smile is ear-to-ear and usually inflicted by cutting.

As a Super-Trope of those listed above, all examples of them should be sorted into their respective categories. This page is only for examples of this trope who do NOT fit into the other perpetual-smile categories.



* Jack the Clown in the "Jack In The Box" TV commercials, who's been appearing as a living, ball-faced humanoid since 1995. It disappears when he's particularly perturbed, though.
* Smilin' Bob from the Enzyte commercials. [[StepfordSmiler His smile is particularly creepy...]]
** Not to mention his wife's...
* There were a [[https://www.facebook.com/video/video.php?v=10150242912205152 series]] [[https://www.facebook.com/video/video.php?v=10150242913990152 of]] [[https://www.facebook.com/video/video.php?v=10150269453405152 Medibank]] [[https://www.facebook.com/video/video.php?v=10150269456160152 commercials]], featuring spokespeople who smiled all the time. At the end of the commercials, their smiles would become bigger through CGI, which would imply that their normal smiles were their neutral expression...
* The last incarnation of Advertising/TheBurgerKing-- whom many viewers have found very creepy because of it.

[[folder: Anime and Manga]]
* ''Anime/OsomatsuSan'': Jyushimatsu is almost always smiling with his mouth wide open.
* Sendo from ''Manga/SlamDunk'' is considered as this.
* Kamui from ''Manga/{{Gintama}}''. [[spoiler: Even while killing everyone during the Yoshiwara arc.]]
* Anthy from ''Anime/RevolutionaryGirlUtena'' almost always wears a placid, vapid smile. This, in addition to her DissonantSerenity, is noted by other characters to be creepy and unsettling.
* Kasumi Tendo from ''Manga/RanmaOneHalf'' is never seen without a lovely smile, and doesn't seem to have StepfordSmiler tendencies.
* Despite the fact that he really [[EmotionlessGirl doesn't understand emotions]], Sai from ''Manga/{{Naruto}}'' is a PerpetualSmiler. He has reasons for this though, which do not fall into the other categories.
* Wolfgang Grimmer from ''Anime/{{Monster}}'' doesn't even stop smiling [[spoiler:as he bleeds to death]]. He ''is'' a pleasant person but the smile is just something he was trained to do. At one point he recalls how his wife left him because he couldn't stop smiling even when his son died.
* Konata Izumi from ''Manga/LuckyStar'' has a CatSmile that, while not quite perpetual, is her default expression.
* Raquel from ''LightNovel/ScrappedPrincess'' is perennially cheerful no matter what's going on.
* Itsuki Koizumi from ''LightNovel/HaruhiSuzumiya'' is almost never seen without a smile. Even in Surprise when [[spoiler: Fujiwara threatens to kill Haruhi, Koizumi continues to smile even though [[BewareTheNiceOnes he's clearly pissed off.]]]]
* Gin Ichimaru (pictured above) and Sousuke Aizen from ''Manga/{{Bleach}}''.
* Mana from ''Anime/YuGiOh'', more in the anime than in the manga.
* God from ''Manga/OyasumiPunpun''
* Elmer C. Albatross of LightNovel/{{Baccano}} is always smiling and happy. He'd be a MessianicArchetype were it not for the fact that there are times where one shouldn't be smiling and jokey, so he just comes across as creepy. Oh, and he's friends with [[MadScientist Huey Laforet]].
** Similarly, the characters Isaac Dian and Miria Harvent, the KindheartedSimpleton [[JustLikeRobinHood criminal]] duo are almost always in a positive mood, even when facing possible death. Of course, [[spoiler: they're both immortal and unable to die anyway]], but they never really notice.
* [[MadScientist Professor Souichi Tomoe]] of ''Anime/SailorMoon S''. Heck, for most of the series, the only thing we ever see of his face are his ScaryShinyGlasses and his big, open-mouthed smile.
* Jail Scaglietti of ''Anime/MagicalGirlLyricalNanohaStrikers'' is another [[MadScientist perpetually happy fellow]]. Impending defeat and imprisonment couldn't even make him drop his smile.
* ''Manga/MahouSenseiNegima''
** Kaede is always smiling mysteriously, to go along with her EyesAlwaysShut. She isn't actually very mysterious as a ''character'', having no secrets to hide, she just looks it. Unless she's so good at hiding secrets that we don't even suspect them.
** Albireo Imma a.k.a. Ku:Nel Sanders also has a perpetual CheshireCatGrin, although he's generally much more suspicious than Kaede.
* [[{{Shinigami}} Ryuk]] from ''Manga/DeathNote''. [[SlasherSmile It's creepy]]. He only broke it once when Light snapped at him after [[spoiler:offering the eyes after meeting L]].
* ''Manga/DGrayMan'' has the Millennium Earl, who smiles even when he's pissed.
* Kousaka from ''Manga/{{Genshiken}}'', always has the same expression, [[ThePollyanna no matter what]] takes place.
* Xellos from ''LightNovel/{{Slayers}}''.
* Takeshi Yamamoto from ''Manga/KatekyoHitmanReborn'', for the most part. When he stops smiling though, you had better start hoping you can run faster than the baseball player, because you're about to get screwed over epically because Yamamoto is ''ticked off''.
* Pride and Ling Yao from ''Manga/FullmetalAlchemist''
* Ariel from ''LightNovel/IsThisAZombie''
* Mikako from ''Manga/HeavensLostProperty''.
* Ling-Ling from ''Manga/RosarioToVampire''. Justified, since she's [[CatchPhrase already dead]], and thus has nothing left to worry about.
* Ojisan of ''Manga/YokohamaKaidashiKikou'' is always grinning.
* Thailand and Spain from ''Webcomic/AxisPowersHetalia''.
** Russia is almost never seen without a smile on his face, which unnerves most others, as they can never be sure [[PsychopathicManchild exactly what he's thinking]] at any given time.
** Portugal is this as well, unsurprising considering his relation to Spain. He smiles cheerfully even when threatening or insulting Spain.
** Denmark is extremely cheerful and almost always smiling.
* Tchaikovsky's default expression is a pleasant smile, usually with closed eyes. His smile can become quite scary when he's about to do something morally questionable or when he is angry. He lampshades it in chapter 11.
* Kio from ''Manga/{{Loveless}}''.
* ''Manga/OnePiece''
** Kokoro always has a huge, slightly creepy smile, regardless of her actual feelings at the time.
** Pirate Captain Urouge the Fallen Monk always sports a large grin on his face, even in dire situations.
** Koala. Until Fisher Tiger broke down her StepfordSmiler façade, it was forced because of her trauma as a former slave, but after the event, it became genuine.
** Wanze the ramen chef is always smiling even when he's scared or angry, he has the same goofy grin for almost every emotion he displays.
* Hao Asakura from ''Manga/ShamanKing''. And his twin Yoh, to a lesser extent (his smile is more genuine).
* Misaki in ''LightNovel/ThePetGirlOfSakurasou''; her smile will only drop when her relationship with Jin is brought into question.
* [[TheDragon Seta Soujirou]] from ''Manga/RurouniKenshin'' always has a pleasantly angelic smile in his face, even when slashing your throat with a katana.
* ''Literature/TheLegendOfSunKnight'': The Sun Knight is never seen without a smile on his face... [[StepfordSmiler Even if he really, really hates the recipient.]] He's very good at making it look natural, however.
* [[MadScientist Gensei Kihara]] from ''Manga/ACertainScientificRailgun'', because he has '''NO''' remorse at all for his incredibly depraved actions.
* Nightmare from ''Anime/KirbyOfTheStars''. The only exception was when Tiff pulls out the Warp Star in Kirby's dream.
* Saya from ''Manga/ServantXService'' smiles 80% of the time even when angry.
* Shalnark in ''Manga/HunterXHunter'' is always smiling, even as he's mercilessly mowing down Mafia goons. He seems to be an an almost perpetual state of calm happiness. The only thing known to offend him is having to use an ability that makes him lose control of himself, as it renders him unable to experience the thrill of killing people.
* ''Manga/ShokugekiNoSoma'' has Satoshi Isshiki, a very easygoing party animal who is rarely seen without a wide smile across his face.
* Lucoa from ''Manga/MissKobayashisDragonMaid'' combines this with EyesAlwaysShut, and only ever drops it when she's being accused of sexual deviance.
* In ''Manga/MyHeroAcademia,'' one thing that [[EmpoweredBadassNormal Izuku]] admires about [[SupermanSubstitute All-Might]] is that he's always smiling, no matter how bad the villain attack or disaster that he's involved in. He quickly learns that All-Might is a StepfordSmiler upon meeting him (and in fact, [[HenshinHero his normal form]] is closer to a PerpetualFrowner), but that just ties into the story's {{Determinator}} themes. It's also notable that Izuku's first hero costume, which explicitly takes cues from All-Might's appearance, [[https://vignette.wikia.nocookie.net/bokunoheroacademia/images/2/21/Izuku_Midoriya_First_Hero_Costume_Full_Body_Anime.png/revision/latest?cb=20151221053816 has a big toothy grin on the mask]].
* Sebastian Michaelis from ''Manga/BlackButler'' always carries a courteous smile on his face, whether he's doing regular butler duties such as cooking, cleaning, [[SlasherSmile killing enemies]], etc...

* This is a characteristic of sculpture from the Archaic period. One notable example is the "Dying Warrior from the Temple of Aphaia", which depicts a wounded man pulling an arrow from his chest...with a cheerful smile.

[[folder:Comic Books]]
* SelfDemonstrating/TheJoker, obviously (his appearance was based partly on the [[Creator/JDSalinger Laughing Man]]). So perpetual is ''his'' scary grin that if he ever ''stops'' grinning for an extended period of time, it's like his version of the BrokenSmile, and it's a sure sign that either something has very definitely gone wrong with him (more so than usual, that is), or the proverbial crap has gotten seriously real.
** Well, make that every incarnation of the Joker except Heath Ledger in ''Film/TheDarkKnight'', who has a GlasgowGrin.
* Also from Franchise/TheDCU:
** ComicBook/TheCreeper.
** There's also Mad Harriet who's smile is quite similar to the Joker.
* For the first portion of his appearance in ''ComicBook/{{Transmetropolitan}}'', Presidental candidate Gary Callahan is one of these. That's why they call him "The Smiler" (also to contrast with incumbent "The Beast"). He rapidly loses the quality once he starts dealing with Spider Jerusalem.
* Mojo, from the marvel universe, has a perpetual grin aided by wires stretched across his face and teeth much too large for his mouth. Though he cackles and giggles constantly anyway.
* Alcman, the [[ComicBook/WilqSuperbohater Wilq's]] sidekick, is always drawn with a wide smile on his face and closed eyes, no matter how dangerous or confusing is the situation.

[[folder:Fan Works]]
* ''Webcomic/AxisPowersHetalia'' fanfic ''[[https://www.fanfiction.net/s/11886910/1/Gankona-Unnachgiebig-Unità Gankona, Unnachgiebig, Unità]]'': Italy is this. Sometimes the smiles are real, sometimes they [[StepfordSmiler aren't]].
* Calvin [[SubvertedTrope briefly]] becomes one of these prior to the introduction of the [[TimeStandsStill Time Pauser]] in ''Fanfic/CalvinAndHobbesTheSeries''.
* Cedric Diggory in ''Theatre/AVeryPotterMusical''.
* Shinigami Kira in ''Manga/DeathNote'' fanfic Fanfic/ApplesEqualsCyanideEqualsLight has a small, frozen smirk on his marble face.
* Doctor Strange in ''Fanfic/ChildOfTheStorm'' seems to have small GrinOfAudacity on his face at pretty much all times. Since he's the best [[TheChessmaster chessmaster]] in a setting practically defined by its colossal GambitPileup, it's justified.
* Chester from ''Fanfic/PacificWorldWarIIUsNavyShipgirls'' is this due to always being in a cheerful mood, [[spoiler: [[OhCrapSmile even after accidentally hitting Arizona with Maury's shield]].]].
* It has been noted in ''Fanfic/NeonMetathesisEvangelion'', even by Kaji himself, how he is constantly smirking. At one point, Kaji also complains how Kaworu is constantly smiling, something also noted by others.

* Most of the toys from the ''WesternAnimation/ToyStory'' series are this in their 'toy' mode.
* Most of the hero characters in the Creator/{{Rankin Bass|Productions}} StopMotion {{Christmas special}}s had built-in smiles, which made it unsettling when they had to be angry or sad.
* Ed the hyena from ''Disney/TheLionKing'' is always smiling. The only instances he doesn't smile is when he's trying to warn Banzai and Shenzi that Simba and Nala are escaping and later when hears Scar outing them as the reasons why he's evil.
** He also cried in an episode of the TV series.
* [[Disney/{{Cinderella}} "Cindy"]], [[Disney/SnowWhiteAndTheSevenDwarfs "Bianca"]], [[Disney/TheLittleMermaid "Hi]][[Disney/{{Mulan}} me"]], [[Disney/ThePrincessAndTheFrog "Iria"]], and [[Disney/{{Aladdin}} "Zade"]] from ''[[Creator/VideoBrinquedo Little Princess School]]'' for some reason [[NightmareFuel never. stop. smiling.]]
* ''WesternAnimation/TheEmojiMovie'' has the aptly-named Smiler, who continues grinning even as she's threatening to do horrible things to Gene and his friends for upsetting the status quo in Textropolis.

[[folder:Films -- Live-Action]]
* Creator/MichaelSheen's portrayal of UsefulNotes/TonyBlair in ''Film/TheDeal2003'' and ''Film/TheQueen'' covers just about the whole range of possible smiles, to the point where it starts to feel like his [[Literature/{{Discworld}} teeth are following you around the room]]. Which is TruthInTelevision.
* Atom in ''Film/RealSteel''. His face (if he has one) is obscured by a metallic mesh that only shows his eyes, but there are seams in the mesh that resemble a nose ridge and a smile. It helps highlight his child-like appearance, which is most noticeable when his Shadow Function is activated.
* [[https://www.youtube.com/watch?v=VGjY5SsOHoM The Smile Man]], short movie about man who damages his spine cord and makes his his face smile forever.
* Martin Freeman's character in ''Film/WildTarget'' continually flashes a big smile at whomever he's talking to. Since he's a contract killer, this is slightly unsettling as well as annoying.
* ''Film/TheWorldOfKanako'': Detective Asai is always upbeat, smiling and holding his lollipop despite being surrounded by crime. It turns out that [[spoiler:he has an interest in a resident prostitution ring and wants to hide this]].

* ''Literature/TheManWhoLaughs'' (''L'Homme qui rit'') is a man who ''literally cannot stop smiling'' as [[BodyHorror he has no cheeks]] (he was kidnapped by gypsies as a baby, who mutilated him like this to make money showing him off).
* ''Literature/AlicesAdventuresInWonderland'' has the Cheshire Cat and his [[CheshireCatGrin trademark grin]].
* Ella in ''Sunny Ella'', though what kind of smile it is changes depending on whose point of view we're reading.
* Jon Masters from Creator/DaleBrown's books.
-->"The bastard never stops smiling, too. You notice that? Always with the damned grin on his puss. I don't trust somebody who grins all the time--it usually means they found someone else to put the blame on."
* ''Literature/TheHungerGames'': Caesar Flickerman.
* Part of Spinnock's charm in ''Literature/MalazanBookOfTheFallen''.
-->''The Slash that was his mouth was fixed in a grin, an expression that rarely wavered.''
* Theon Greyjoy is depicted as this in the early books of ''Literature/ASongOfIceAndFire''.
* Tattletale of ''Literature/{{Worm}}'' is described as always having a foxlike grin.
* ''Literature/ArmadilloFists'' has Mr Happy, [[ExactlyWhatItSaysOnTheTin who's always happy.]] In fact, he desperately wishes he didn't have to be, but a neurological disorder has made it so [[GettingSmiliesPaintedOnYourSoul he's incapable of sadness, fear, or any other feeling except happiness.]]

[[folder:Live-Action TV]]
* The Gentlemen from the ''Series/BuffyTheVampireSlayer'' episode "Hush".
* Jonas Quinn of ''Series/StargateSG1'' is a prime example. He tends to smile when the team is flying through space or he encounters something fascinating for the first time. This is often [[LampshadeHanging lampshaded]] by O'Neill.
* Scorpina from ''Series/MightyMorphinPowerRangers'' was this (as was, by default, Lami, her ''Series/KyoryuSentaiZyuranger'' counterpart) despite being one of the more serious villains (by ''MMPR'' standards, anyway). It was obvious that she genuinely enjoyed fighting the Power Rangers.
** This was more Ami Kawai than Scorpina. [[RealLife/MeanCharacterNiceActor Ami herself is a very sweet, kind, and warm lady who herself is always smiling, who is one of the few former Sentai actors to happily associate herself with the series, even 20+ years later]]. It also says a lot about her acting abilities that she can effectively play a ruthless villainess despite a kind, sweet, always-smiling appearance without causing any cognitive dissonance.
* Jerome Valeska from ''Series/{{Gotham}}''. Then again, considering [[SelfDemonstrating/TheJoker who he is likely to become]], this is to be expected.
* While he's capable of being serious and stoic when he has to, especially when dealing with tough topics as mass shootings, [[Series/TheDailyShowWithTrevorNoah Trevor Noah]] is always smiling or maintaining a positive attitude.
* RealityEnsues in ''Series/TheCrown2016'' when the recently-crowned Elizabeth must maintain her regal smile through a jam-packed touring schedule. She actually strains the muscles of her face and needs an injection for the pain.
* [[PsychopathicManchild Parado]] from ''Series/KamenRiderExAid'' has [[UncannyValley an unsettling smile]] which he wears most of the time. It's justified as he is usually having fun and as video game character born into reality he doesn't have a solid grip on human mannerism. [[KillAllHumans His idea of fun]] doesn't exactly match up [[DeadlyGame with common expectations]]. If he drops the smile, you know you're screwed. Once instance of this actually prompted OhCrap from the then BigBad.
* ''Series/JessicaJones2015'': One of the Kilgrave victims that comes forward is a woman who claims that Kilgrave made her follow him around constantly smiling for (at least) hours on end.

* Music/AphexTwin is always depicted with a huge, [[TheUnSmile unsettling]] [[SlasherSmile smile]] on his face. Taken to its logical conclusion in multiple music videos in which actors wear masks of his face frozen in his trademark expression.

* The Piraka and their whole species in ''Toys/{{Bionicle}}''.
* {{Lego}} minifigures, usually.
** The older kind more so; newer ones (from around the mid-to-late nineties on) have plenty of frowns, neutral expressions, and other miscellaneous emotions to perpetually display. Some of their heads can be turned around for different expressions.
** Within that, Flex from ''Alpha Team'' is said to always smile "even when danger threatens".
** A ''WesternAnimation/RobotChicken'' [[http://www.youtube.com/watch?v=R2i_CKDrZUw sketch]] [[LampshadeHanging lampshaded]] this to creepy effect by depicting a spaceship accident resulting in the astronauts inside burning, their faces still stuck in PerpetualSmiler mode while screams were overdubbed. Despite the sketch's BlackComedy, it crosses into nightmarish, especially when one of the firemen yells "Their faces! Their horrible faces!" before another cut to them smiling/screaming.
* Franchise/{{Barbie}}.
** Lampshaded in the HilariousOuttakes of ''WesternAnimation/ToyStory2'':
--->'''Tour Guide Barbie:''' Oh my gosh, my cheeks are killing me! I can't keep smiling like this anymore. I am exhausted. I think I need a break.

[[folder:Professional Wrestling]]
* The Sunami half of Su/Ka, even when denouncing the TagTeam and proclaiming it [[ItsAllAboutMe everything was about him]] following TheReasonYouSuckSpeech from the Ballard Brothers, even while boasting about how he was going to beat the rest of the Vendetta Pro roster to prove he was not just another smiling face.
* Hiroyo Matsumoto has the philosophy of always trying to live happy, and of beating people's asses while happy.
* Since he won his first title in Wrestling/{{N|ationalWrestlingAlliance}}WA Vendetta Pro, Ricky Ruffin smiled as much as possible.[[/folder]]

[[folder:Video Games]]
* Henry from ''VideoGame/FireEmblemAwakening'' is always smiling, whether he's helping a wounded dog, practicing magic, thinking about murdering people, drinking blood, murdering people, sacrificing people for his spells, or raising an army of the undead to attack civilians, he's always smiling. He's just a happy guy. [[spoiler:At least, that's what he wants you to think.]]
** Oscar of ''VideoGame/FireEmblemTellius'', as parodied in [[http://hail-nekoyasha.deviantart.com/art/Oscar-is-a-Smilin-Fool-24346195 this comic strip]].
* The Happy Mask Salesman from ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' and ''VideoGame/TheLegendOfZeldaMajorasMask'' combines this with EyesAlwaysShut unless you press his BerserkButton.
* The shape-shifting space creature, Jenova, from ''VideoGame/FinalFantasyVII''. After being excavated by scientists, "she" is locked in a gnarled human appearance for several years, with an empty smile visible beneath her helmet.
* The Kid from ''VideoGame/IWannaBeTheGuy'' is forever grinning ecstatically, in contrast to what one might expect from someone who is [[PlatformHell rarely more than a few seconds from death]].
* Maxwell in ''VideoGame/{{Scribblenauts}}'' is always smiling, even when he's getting eaten alive or otherwise mauled.
* Evil Otto in the early [=1980s=] arcade game ''VideoGame/{{Berzerk}}'', who is basically a smiley button, who comes onscreen to chase after the player and to electrocute him, passing through walls and destroying robots along the way. On top of that, he's also [[TheJuggernaut invulnerable]]. Designer Alan [=MacNeil=] put Evil Otto in the game because [[TakeThat he hates smiley buttons]].
** Evil Otto also appears in the game sequel ''[[http://www.arcade-museum.com/game_detail.php?game_id=7853 Frenzy]]'', but he loses that smile when the player can now shoot him down.
* [[IronicNickname The Sorrow]] of ''VideoGame/MetalGearSolid3SnakeEater'' is always seen smiling, despite his [[CapsLock GOD DAMNED NAME.]]
* ''VideoGame/InazumaEleven'''s 3D character models have fixed expressions. Characters who smile will smile even though the ball hits them. Masaru Gojou always has a rapist's face, and Hijikata will never stop grinning.
* Miranda in ''Franchise/MassEffect'' rarely drops the grin she wears. Even when it looks like the suicide mission will become just that, she still looks happy.
** In the third game, with the change in the graphics engine, her smiles appear in a more natural frequency, but she still smiles more often not.
* ''Franchise/{{Pokemon}}''
** Many Pokémon such as Wooper and Sunflora are almost always smiling in the 3D games (Exceptions typically for when they attack or get hit in battle or if you upset them in X/Y's Pokemon Amie feature).
*** Wynaut is literally this in series canon according to its Ruby Dex entry. One has to look at its tail to determine its mood.
** Emmet in ''VideoGame/PokemonBlackAndWhite''.
** The player character in ''VideoGame/PokemonSunAndMoon'' spends a good majority of the cutscenes in the game smiling, which unfortunately ([[AlternateCharacterInterpretation or happily]]) makes it seem like your character is enjoying everything that occurs in the game's darker second half while the other characters are either horrified or going insane.
* Dimentio in ''VideoGame/SuperPaperMario''.
* Yoshis from the Franchise/{{Super Mario Bros}} and VideoGame/YoshisIsland games are always seen happy unless they are injured.
* Poppy Bros from the ''VideoGame/{{Kirby}}'' series has this to imply a MadBomber vibe.
** Taranza, the [[spoiler:supposed]] main antagonist from ''VideoGame/KirbyTripleDeluxe'' has this, too.
** Kirby himself is a downplayed example, at least when AmericanKirbyIsHardcore doesn't come into play. If he's not, he'll have a confused expression on his face.
* In ''Videogame/StarWarsTheOldRepublic'', Consular companion Felix Iresso is rarely without a smile. His maximum affection achievement is even called "The Cheerful Soldier." [[ReassignedToAntarctica Assigned to Hoth]] with a ton of jumpy privates and a mission he was likely to set up to fail? He's not complaining, the job needs to be done. In the middle of a firefight with a bunch of Imperials and outnumbered three-to-one? ''"Broke a sweat on that one."'' he says. Career stalls as he's bounced from rear-end outpost to rear-end outpost? Beats being in an Imperial prison. Missing a week's time from ''being'' in an Imperial prison and [[spoiler: having a Sith holocron forcibly downloaded into his head]]? Well, at least he can live to tell the tale. If he ''stops'' being laid-back and cheerful, [[OOCIsSeriousBusiness you have a big problem on your hands]].
* The ''VideoGame/AnimalCrossing'' Villager in ''VideoGame/SuperSmashBrosForWiiUAndNintendo3DS'' is seen smiling all the time, while attacking his opponents with seemly lethal weapons. This led to him becoming a MemeticPsychopath.
* Hazama, [[Manga/{{Bleach}} Gin Ichimaru's]] {{Expy}} from ''VideoGame/BlazBlue'' seems to be this.
* Sans and Papyrus in ''VideoGame/{{Undertale}}'' are always grinning, the former in a laid-back, vaguely smug fashion and the latter in an eternally cheerful, goofy kind of way. The closest thing they ever do to frowning is turning the corners of their mouth turn down slightly when upset. It helps that they're skeletons. During a [[KillEmAll Genocide run]] they even smile if you kill them. Papyrus because [[spoiler: he feels your life is going down the wrong way and he wants you to know that you can be a better person, even if you don't think you can, and to that end he never lets his encouraging smile falter]] and Sans because, at this point, [[spoiler: [[StepfordSmiler you've killed everyone]] [[BrokenSmile he knows and love.]] ''And'' because he knows that you'll probably reset everything again anyway.]]
* Claptrap from ''VideoGame/Borderlands2.'' While he doesn't have a mouth, his voice is programmed to always sound happy, even though he's depressed.
* Bendy from ''VideoGame/BendyAndTheInkMachine'' seems to always have been drawn with the same grin. In fact, you can even find a character sheet showing that he's always smiling regardless of how he feels.

[[folder:Visual Novels]]
* Leo Shishigami, protagonist of ''VisualNovel/RoseGunsDays'' Season 1, never drops neither his smile, nor his laid-back attitude. The very few times he does, you know he is ''really'' serious.

[[folder:Web Animation]]
* The Whites from ''WebAnimation/LuckyDayForever''.
* The titular demonic hamster from the ''WebAnimation/SockSeries'' never stops smiling even while being terribly maimed.
* Nora Valkyrie of ''WebAnimation/{{RWBY}}'' is always smiling. In fact, her smile grows even bigger when she's fighting, and only falters when her teammate Ren is hit.

[[folder:Web Comics]]
* Trudy of ''Webcomic/GeneralProtectionFault'' is one, combined with BitchInSheepsClothing. As such, her "Nega" counterpart is a PerpetualFrowner.
* [[TricksterArchetype Coyote]] from ''Webcomic/GunnerkriggCourt'', who has a near-perpetual CheshireCatGrin. Even on the rare occasions when it vanishes, though, his upbeat attitude never does.
* The Caped Crustacean from ''Webcomic/BeyondTheCanopy'' seems to have a grin permanently on his face. As it turns out, he's just wearing a smiling mask.
* ''Webcomic/{{EVIL}}'': Gabriel is almost always wearing a [[CheshireCatGrin shit-eating grin]].
* Smiling Guy from ''Webcomic/PowerNap'', who smiles even as he is kicked out of the way and his desk set on fire.
* Alastor and [=KayCee=] from ''Webcomic/{{Zoophobia}}'' are never, not ever seen without some sort of [[LaughingMad insane grin]] on their faces.
* ''Webcomic/{{Katamari}}''
** [[PurityPersonified June]] is ''always'' smiling, regardless of the situation.
** Opeo manages this to a lesser extent; even though he's VERY accident prone, he tries to keep a sunny attitude about it.
* In ''Webcomic/TheDragonDoctors'', Sarin fits this mold quite well.
* ''Webcomic/{{Godslave}}'''s Blacksmith girl always has a smile on her face, in contrast to her PerpetualFrowner job partner. This may be her reaction to his antics, though.
* Anesu from ''Webcomic/{{Spacetrawler}}'' is almost always smiling, fitting for the most energetic and upbeat member of the cast.

[[folder:Web Original]]
* Blog/TheComicsCurmudgeon describes TJ from ''Luann'''s smile as a death-rictus.
* WebVideo/EightiesDan is almost always smiling and cheerful, especially when he's taken a good hit of cocaine.
* [[Podcast/FalloutIsDragons Doctor Javolt]] cannot stop smiling due to nerve damage.
* In ''Literature/VoidDomain'' the necromancer Sawyer is never seen without a SlasherSmile on his face.
* Mr. Winkle from the ''WebVideo/SuperMarioLogan'' series ''Bowser Junior's 1st Grade!'' is always cheerful and authentic about the situation, even when he's about to get arrested by a down-to-earth police officer.

[[folder: Western Animation]]
* A number of the [[WesternAnimation/TheMrMenShow Mr. Men and Little Misses]], but especially Mr. Tickle, Mr. Happy, and Little Miss Sunshine.
* The eponymous ''WesternAnimation/RubyGloom'' since she [[CatchPhrase always looks on the bright side]] -- in direct contrast to her aptly-named friend Misery.
* ''WesternAnimation/PhineasAndFerb''
** Phineas rarely changes to any other expression -- in the whole series, he was only truly sad during the ChristmasSpecial, and once angry and frantic in ''Summer Belongs to You!'' and ''Mission Marvel''.
** Isabella could count, too, but she's more prone to expressing anger than the eponymous {{Everyman}}.
* In the cartoon of ''WesternAnimation/WheresWaldo'', Waldo almost always smiles.
* The Joo Dees from ''WesternAnimation/AvatarTheLastAirbender'' are ''{{brainwashed}}'' to do this.
* Nick from ''WesternAnimation/InvaderZim''. Probably because he ''really'' likes having [[GettingSmiliesPaintedOnYourSoul that happiness probe in his brain]]!
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has Pinkie Pie, who is always smiling save for a few... ''[[BerserkButton notable]]'' [[BreakTheCutie exceptions]].
** The season 5 premiere takes place in a small village where ponies are forced by Starlight Glimmer to keep unnatural smiles.
* In ''WesternAnimation/AdventuresOfTheGalaxyRangers'', Zozo is a very cheerful and laid back guy, even in the middle of a brawl with guys twice his size. It's not like he ''can't'' stop smiling, it just takes a lot for him to choose not to.
* ''WesternAnimation/TazMania'': Whatever he's actually feeling, Bull Gator is, in verbiage and tone, almost invariably cheerful and collected about the situation. Even when he's facing down a Tasmanian Devil who regards mauling him as good, clean, Sunday-afternoon fun.
* In ''WesternAnimation/ThomasTheTankEngine'', the title character kept his grin throughout the whole entire episode of "Thomas And Trevor".
* Otto from ''WesternAnimation/TimeSquad'' is this. Even when he gets sad or angry, he ends up bouncing back up eventually.
* Kit Fisto from ''WesternAnimation/StarWarsTheCloneWars'' always has a bit of a smile on his face, making his actual smile a rather big cheesy grin.
* The [[WesternAnimation/LooneyTunes Road Runner]] virtually always wears a carefree smile. Not simply a matter of a bird's bill being immobile, as Daffy Duck and Tweety Bird can both attest.
* Ms. Frizzle from ''WesternAnimation/TheMagicSchoolBus'' is almost always smiling and enthusiastic, even when she and the class are in precarious situations during their field trips.
* Dr. Paula "Hutch" Hutchison in ''WesternAnimation/RockosModernLife''.
* Gretchen from WesternAnimation/{{Recess}} (partially due to her large buck teeth) fits a rarely explored RealityEnsues version of this trope as she has a very pronounced lisp or some other kind of speech impediment that indicates excessive saliva.
* The default expression of Beavis from ''WesternAnimation/BeavisAndButtHead'' is a vacant smile. While watching Henry Rollins' music video for the song "Liar", Butt-Head says that he has a cool smile. Beavis then says "Yeah, I've got a cool smile too, check this out. ''({{beat}})'' See?"
* Freaky Fred from ''WesternAnimation/CourageTheCowardlyDog'' has the ''creepiest'' smile that seems very immutable. His personality doesn't help either.
* Bill Cipher from ''WesternAnimation/GravityFalls'' has no mouth in his pyramid form, but his affable demeanor suggests this. When [[spoiler: he possesses Dipper's body]] and gains a mouth in "Sock Opera", it spends most of the time in a grin that ranges between "cheerful" and "[[SlasherSmile psychotic]]".
* The Ice Dancers couple from ''WesternAnimation/TotalDrama - The Ridonculous Race'' strive to smile constantly, which comes off rather creepy. Their justification is that the cameras can pop up anytime. That said, Josee especially [[HairTriggerTemper has been known to make less happy expressions]].
* ''WesternAnimation/BunsenIsABeast'': You could count the amount of times the titular character ''doesn't'' smile each episode with just one hand.
* ''WesternAnimation/TheRuffAndReddyShow'': Salt Water Daffy constantly sports a large, maniacal grin.
* ''WesternAnimation/DofusTheTreasuresOfKerubim'' has The Baron from the three-parter "Ecaflip City". He's the most successful gambler in the city, and always has a smug grin on his face. [[spoiler:Though he loses it when Kerubim refuses to make a bet with him, and he's revealed to have been a puppet of the Ecaflip God the whole time.]]

* This is a symptom of the [[http://en.wikipedia.org/wiki/Angelman_syndrome Angelman Syndrome]], a genetic disorder characterized by development delay, speech impediment, movement or balance disorder, and frequent laughter and smiling.
* A running theme of the 2012 United States presidential debates. In the first debate, Mitt Romney smiled constantly and was complimented for his confident body language, while Barack Obama was roundly criticized for his annoyed and detached expression. During the vice presidential debates, Joe Biden noticeably made an effort to gain lost ground by smiling broadly throughout the debate and laughing frequently. Although some criticized his excess, he was roundly considered to have won the debate. In the second presidential debate, Obama smiled confidently far more often, obviously in response to previous criticism.
* [[http://en.wikipedia.org/wiki/Judah_P._Benjamin Judah P. Benjamin]], Jewish Senator and Secretary of State of the Confederate States of America, was almost always photographed with a [[SmugSmiler smug little smirk]]. Because it was so unusual in the 19th century to purposefully smile in photographs, this was apparently his default expression.
* [[http://en.wikipedia.org/wiki/Gail_Halvorsen Colonel (ret.) Gail Halvorsen, USAF]]. And '''HOW!''' In every single picture of this guy, from 1948 to 2012, he's wearing a huge, ridiculous smile. Definitely justified in that it was his idea to drop candy on Berlin during the famous [[http://en.wikipedia.org/wiki/Berlin_Blockade Airlift]].
* This will involuntarily happen to a lot of people when out in the bright sunlight as a consequence of squinting hard against the sun.

* One of the reasons why Formula One driver Daniel Ricciardo [[EnsembleDarkhorse is popular among the fans]] is due to his trademark smile. He's almost always shown smiling, and when you see him ''not'' smiling, you know that he has a big, ''[[{{Understatement}} big]]'' problem. [[NeverLiveItDown Just ask the Red Bull pit crew members following the 2016 Monaco Grand Prix.]]
** Similarly, Hines Ward, a former wide receiver and Super Bowl MVP for the Pittsburgh Steelers, was known for constantly having a smile on his face during games. Even when he was flattening people with blocks, and even when he sprained his knee and had to leave an AFC Championship game against the Steelers' rival, the Baltimore Ravens, he was smiling. When he fumbled the ball trying to extend a play against the Tennessee Titans, that the Titans would recover, when simply covering the ball and taking the tackle would have let the Steelers try a relatively short field goal to take the lead in the final seconds, he was so pissed off about it he ''finally'' stopped smiling on the sidelines. Which the TV announcers would lampshade, saying that they couldn't ever recall him being mad enough over football [[OOCIsSeriousBusiness to stop smiling like a loon.]]
* In her autobiography, Creator/ShirleyTemple claims that when she started school, her teachers called her mother and asked why her daughter was constantly smiling.
