[[caption-width-right:300:You get exactly one guess as to [[JekyllAndHyde which]] [[SplitPersonality side]] is [[SplitPersonalityTakeover in control]].]]

->''"Some smiles show cheer; some merely show teeth."''
-->-- '''[[http://ww2.wizards.com/Gatherer/CardDetails.aspx?name=Abyssal%20Hunter Abyssal Hunter]] FlavorText''', ''TabletopGame/MagicTheGathering''.

In the animal kingdom, baring your teeth is a sign of aggression. In the case of humans -- well, there's something very disconcerting about a smile that doesn't have an ounce of happiness in it. It's downright frightening when the smile is in anticipation of pain or death -- yours, probably. Needless to say, the Slasher Smile does not inspire warmth in anyone who sees it.

The Slasher Smile is the evil sibling of the CheshireCatGrin. In general, the difference is in the eyes of the character. If the eyes sparkle, or are mischievously wicked, it's a Cheshire Cat Grin. If, however, the eyes are clearly crazy or malevolent, it's a Slasher Smile. If the grinning person is [[KnifeNut holding a knife]] or [[AnAxeToGrind an axe]] or some other implement of painful and often bloody death, it's best to assume the worst.

While the CheshireCatGrin is a staple of TheTrickster, generally one of the good guys, the Slasher Smile is the staple of the AxCrazy, unless said hero is a particularly dark or vicious AntiHero. Only expect to see a "nice" hero with a Slasher Smile if they've been possessed or suffered a major FreakOut or if they have been taken over by their SuperPoweredEvilSide. Also, a devious [[TheChessmaster Chessmaster]] or MagnificentBastard is unlikely to look like this - it's too ObviouslyEvil, and they prefer the subtler PsychoticSmirk.

No, the Slasher Smile is more appropriate for TheDragon, the MadScientist, and most especially {{Serial Killer}}s, but it can happen with any character who is gleefully violent and/or fits any "wild crazy person" stereotypes. Beings who hunt and eat victims we are supposed to identify with will also often have Slasher Smiles... in their case, it means "Hello, lunch!"

Some characters with a Slasher Smile [[PerpetualSmiler wear the grin all the time]] -- [[FrozenFace in fact, it's physically impossible for them to move their face out of it.]] For many, this has the added worry of making it harder to tell what they're thinking or feeling, because their face betrays no expression beyond the smile.

[[IThoughtItMeant Not to be confused with a]] [[GlasgowGrin Slashed Smile]] (although they sometimes overlap), and has nothing to do with the pleased smiles of SlashFic fans upon the detection of impending HoYay. Hopefully.

Contrast DissonantSerenity for a calm mood which isn't the slightest bit more reassuring. When the smile is merely creepy, it's TheUnSmile. May be part of the fear behind the MonsterClown. See also TechnicallyASmile. Also contrast GrinOfAudacity.

!!Examples

[[foldercontrol]]

[[folder: Anime and Manga]]
* Harry from ''Manga/OutlawStar'' gives a creepy one when Gene figures out he's been trying to MindRape Melfina and another when talking to Melfina about how they're NotSoDifferent.
* ''Manga/KatekyoHitmanReborn'': Birds. And Mukuro as well. Hooo Boooy...
** A few members of Tsuna's [[strike: harem]] family do this sometimes too, namely Gokudera, and Hibari.
** Xanxus too. His smile is ''terrifying'' [[strike:[[DracoInLeatherPants and hot]]]].
** Bel [[spoiler: and his twin]]. Who also adds CheshireCatGrin and [[GigglingVillain evil giggles]] to the mix.
** A certain BigBad named Byakuran.
* Dr. Hell from ''Anime/MazingerZ'' and ''Anime/GreatMazinger'' never smiled. He GRINNED (usually when he thought he was winning or believed he had won. Or simply when he felt people were frightened of him). And it was deeply disturbing. It was even creepier in ''Anime/{{Mazinkaiser}}''.
** Tetsuya Tsurugi, TheHero from ''Anime/GreatMazinger'', was a BrokenAce usually wore a grim, angry or bitter expression. But when he grinned in battle, it was ''very'' eerie.
* Xellos from ''LightNovel/{{Slayers}}'' has this in spades. It's less common to see him not smiling than to see him with a smile (or a convenient PsychoticSmirk) on his lips, but if he's smiling ''and'' his eyes are open, you're in serious trouble. Especially exemplified as he's sadistically torturing Valgaav in TRY and a highly amused smile never leaves Xellos' face, backed up by a truly psychotic giggle.
* ''Manga/{{Bleach}}'':
** This is used to identify characters who fight for the [[BloodKnight love]] or [[AxeCrazy madness]] of fighting rather than higher ideals, such as with Kenpachi, Ichigo's inner hollow, Ikkaku, Nnoitra, Ginjou, [[spoiler:and Unohana]]. Ichigo sports one in battle sometimes as well.
** This is used to identify [[MadScientist scientists]] unleashing their chance to experiment on others ForScience or reveal any bizarre inventions they have created. This tends to be as much a [[MadDoctor problem]] for their allies as for their enemies. Examples include Mayuri and Szayel.
** It is used to identify creepy characters who cannot be trusted and are hiding ulterior motives, such as [[EyesAlwaysShut Gin]].
** It is used to emphasise a character on the battlefield is unhinged and descending into insanity, such as with Tsukishima and Nianzol.
* ''Manga/FullmetalAlchemist'': Both Envy and Kimbley have serial slasher smiles.
** Greed, [[spoiler: both his first body and in Ling's]], have this. Pride's shadows also usually have this default expression as does [[spoiler: his body after he eats Gluttony]]. Must be a family trait since Father was shown to have one [[spoiler: back in the days where he was only a blob in a flask]] and he can still pull it off as shown [[spoiler: When he leaves his 'human form' which is just a humanoid blob with these and eyes]].
** Barry the Chopper has one built into his helmet.
** Some of the minor characters even have these, such as General Raven, when he's trying to offer someone immortality and in his EyeCatch, and also some of the more unsympathetic State Alchemists that participated in the war.
** Truth almost always has this expression on his face, because [[JerkassGods he's a sadistic dick]] who enjoys handing out ironic but [[DisproportionateRetribution disproportionate punishments]] to people who try to break the laws of the universe. The only exception is [[spoiler:when Ed correctly offers to sacrifice all of his alchemist powers to get Alphonse back]], Truth displays a ''real'' happy smile as he cheerfully [[spoiler:congratulates Ed on choosing the right answer and opens the way for him to retrieve Al and dissolves into nothingness]].
** Wrath from [[Anime/FullmetalAlchemist the 2003 anime version]] constantly has these, especially when he's fighting.
*** Gluttony adopts a slasher smile after [[spoiler:Dante destroys his vestiges of humanity]] in the 2003 anime.
*** Also in the 2003 series, Lust adopts an eerie one when she attacks Scar in the 18th episode.
* AntiHero example and a subversion: Revy from ''Manga/BlackLagoon'' routinely wears this kind of grin when she's busy gunning down bad guys, particularly during the first major shootout of the series, where [[NaiveNewcomer Rock]] sees her smile for the first time and is extremely creeped out. However, that's just Revy on a normal day. What you ''really'' want to watch out for is when she ''drops'' the grin and goes all emotionless and monotone, because that's when she stops pointing her guns at the bad guys and starts pointing them at ''[[AxCrazy everyone.]]''
** In the manga arc ''El Baile De La Muerte'', Roberta, as her sanity continues to spiral downward into {{Ax Crazy}}ville, starts sporting these. And so came the time when she snapped one of Shenhua's throwing knives, WITH HER TEETH, while wearing THE Slasher Smile. BadAss.
** CreepyTwins Hansel and Gretel take this trope to a ridiculous level. Think vampires.
** Balalaika's a kid in a candy store during the "Fujiyama Gangster Paradise" Arc. She's ordering hits, snapping necks, and [[spoiler: holding a gun to Rock's head]] with that ''huge'' grin.
** And, more and more, ''Rock'' has been showing a SlasherSmile. You first see it right at the beginning, when Revy [[TooDumbToLive challenges Rock, a Japanese ''sarariman,'' to a drinking duel.]]
* Anemone from ''Anime/EurekaSeven'' displays a few of these when she fights.
* K of ''Literature/FromTheNewWorld.'' [[http://angryanimebitches.com/wp-content/uploads/2013/01/shinsekaiyori-episode14-24.jpg Holy hell.]] A kid should '''not''' have such a bloody face, let alone unleash a tranquil yet heart-stoppingly horrific smile after killing 1,000 people in a single day.
* Touma of ''LightNovel/ACertainMagicalIndex'', episode nine. So very creepy and so very ''very'' [[CrowningMomentofAwesomeAnime awesome]].
** And {{in|vokedTrope}}tentional. Considering he's not even an antihero, the psychological warfare aspect is neat.
** Accelerator is always seen with an evil smile when he is enjoying a good fight or a massacre, maybe because his awesome powers makes many times the fights boring, for example when an army tried to beat him,[[spoiler: when the Misaka sisters tried to fight him and one the most boring "fights" he had was when Mikoto Misaka tried to attack him, he really looked bored]].
* Agito of ''Manga/AirGear''. He has this whole shark fang thing going on.
* Yomi from ''Manga/GaRei'' puts one on when she's under control of the Sesshouseki. It's even creepier when her eye colour inverts.
* Osaka's attempt to "wake up" Yukari in ''Manga/AzumangaDaioh'' fell into this from a different angle. Osaka always looks a bit blank, and she was half-asleep when she tried it... which just resulted in her standing in the doorway with a blank, empty smile and a large knife. She had no violent intentions, but she sure [[http://www.youtube.com/watch?v=37mPoKQijj8 looked like]] someone was gonna get stabbed.
** Probably ''her''. Earlier in the episode she expressed a lifelong dream of waking someone by banging a ladle on a pan next to their ear. The only thing keeping Osaka from cutting off her own hand was Yukari woke up when Osaka opened the door.
** A slightly more trope-y Slasher Smile (more of a Slasher Smirk) is [[http://www.youtube.com/watch?v=QyPLkjD3-SI&feature=related here]], at about 0:40.
* Dilandau from ''Anime/TheVisionOfEscaflowne'' has every kind of slasher expression in the book.
* There's been a few characters who do this in ''Manga/FairyTail'', but the crown for the most disturbing SlasherSmile goes to an all-around psychopath named [[AxCrazy Jackal]], a member of Tartarus, which he sports while [[spoiler:'''slaughtering the Magic Council''', as well as forcing a SadisticChoice on Lucy involving her choosing whether to save the life of a former Magic Councilor... or a pregnant woman, who was crying and trying to reassure her unborn child that everything would be okay]]. Yes, the Tartarus arc took the DarkerAndEdgier level of this series UpToEleven like never before.
** [[spoiler:Though a machine manages to give him a good run for his money.The arc's DoomsdayDevice,Face,a large pillar with,well a [[{{ExactlyWhatItSaysOnTheTin}} face]] on top,looked kinda stoic when we first see it.It turns out there's more though,and we see some with...rather creepy smiles on them.]]
* Kaguro from ''Manga/{{Kekkaishi}}'' almost constantly has one of these, and an endless supply of lethal blades to back it up.
* Kuroudo Akabane from ''Manga/{{Getbackers}}'''s happy face.
** Ban pulls one as well, specifically just before he fights Fudou.
** Even [[spoiler:Kazuki]] gets to pull this in the manga, both while [[spoiler:BrainwashedAndCrazy]] and under the influence of [[spoiler:his SuperpoweredEvilSide.]]
* Legato Bluesummers from ''Manga/TriGun'' has probably the most nonchalant one ever.
** His boss, Millions Knives, has quite a few of his own.
* ''VisualNovel/HigurashiNoNakuKoroNi'': ''Everyone'' has them by the dozens. [[spoiler:The ''real'' culprit, though, has a perpetually blank appearance, which is even creepier in contrast.]]
** In ''VisualNovel/UminekoNoNakuKoroNi'', we get [[spoiler:[[FanNickname Beatroll and Trollkastel]].]] And [[CreepyChild Maria]].
*** Lamdadelta has this. Especially [[ArtEvolution her sprite]] from the [[UpdatedRerelease PS3 version of the game]]. [[http://static.tvtropes.org/pmwiki/pub/images/lamdadelta_evil_5464.png See for yourself]].
* Almost everyone in ''Manga/{{Hellsing}}'' has one of these.
** It's hard to find a minor/major character in ''Manga/{{Hellsing}}'' who doesn't invoke [[http://s899.photobucket.com/albums/ac200/esetios/?action=view¤t=Hellsingsmiles-1.png this trope]].
* Asuka cracks a lovely example of this smile when fighting the Mass Production [=EVAs=] in ''[[Anime/NeonGenesisEvangelion End of Evangelion]]''.
** And the EVA units gives it right back, as [[http://static.tvtropes.org/pmwiki/pub/images/Eva01NightmareFuelRight.png EVA Unit 01]] and [[http://ghostlightning.files.wordpress.com/2009/04/neon-genesis-evangelion-end-of-evangelion-eva-series-smiles.jpg the Mass-Produced EVAs]] demonstrate.
*** Eva Unit 01's really deserves special notice, because in that picture it's smiling after having already been brought back into the hangar after the fight with Zeruel. [[spoiler: The fight in which it ate Zeruel alive to absorb it's source of unlimited motive power and tore off NERV's restraints, and in doing so completely removed NERV's ability to control it. Past that point the only reason NERV can keep it in the hangar at all is because]] it's ''letting them'' keep it there, and [[spoiler: the soul inside]] is grinning with the knowledge that it's now become [[OmnicidalManiac literally unstoppable.]]
** Even Shinji shows a couple, most of them during the battle with Zeruel.
** Some people regard [[CreepyChild Rei's]] rare smiles this way as well.
*** EndOfEvangelion tosses in Gorn.
** One word: [[http://i89.photobucket.com/albums/k224/nativsis/Anime/Evangelion/MARIIII-1.png Mari]].
* ''Manga/FruitsBasket'': Hatsuharu Sohma's SplitPersonality, Black Haru, has some pretty disturbing smiles that are nonetheless better than the alternative (in the vein of "I'm going to ''love'' kicking your ass" is better than "I'm going to kill you").
* Go ahead, mess with [[spoiler: Shiro]] from ''Manga/DeadmanWonderland''. You're going to wish you never did once [[SuperpoweredEvilSide the Wretched Egg]] takes over and [[http://24.media.tumblr.com/tumblr_lxyclm554b1qzl4tgo1_500.jpg unleashes a unsettling grin]] (complete with a '''''skrkt''''' sound effect, no less).
** [[spoiler:Even moreso [[http://25.media.tumblr.com/tumblr_m6pnv3QDHG1rsqhhxo1_500.jpg without]] [[http://24.media.tumblr.com/tumblr_lq7hbxQMLc1qce4iao1_500.jpg her mask.]]]]
** [[spoiler:Chapter 53 takes the best of both worlds and makes an already chilling smile [[http://www.mangareader.net/deadman-wonderland/53/24 incredibly]] [[http://www.mangareader.net/deadman-wonderland/53/26 worse.]]]]
* When Guts, the AntiHero from ''Manga/{{Berserk}}'', smiles, it is usually one of these. This should be your signal to run, as he's usually in a blood-spilling mood when he's got that grin.
** [[http://static.tvtropes.org/pmwiki/pub/images/Guts_slasher_smile_7502.jpg This one in particular is pretty unnerving.]]
* Frequently sported by Viral from ''Anime/TengenToppaGurrenLagann''.
** Which is fitting, given that [[PettingZooPeople he's part shark.]]
** Simon also gets [[http://www.gurrenlagannepisodes.com/image-gallery?func=detail&id=2246 one of these]] when he [[spoiler:turns on Rossiu and yells at him about how Rossiu's "gods" killed Kamina]].
** Lord Genome in episode 15 sports one while he is beating the shit out of a mecha ''with his bare hands''.
** Kittan gives us two very good Slasher Smiles; [[http://oi53.tinypic.com/4pwdjr.jpg one in the Parallel Works video starring him,]] and [[http://i33.servimg.com/u/f33/12/03/89/51/kittan10.jpg an especially badass one]] during his ultimate CrowningMomentOfAwesome in Episode 25.
* ''Manga/DeathNote'': [[spoiler:As L dies,]] before he [[spoiler:closes his eyes]] he sees Light looking at him with one of these. [[spoiler:Higuchi, too,]] after getting the Shinigami Eyes. One look at that creepy face and death will follow, without the Death Note.
** Light again, during the finale (at least in the manga), sports one so big he gets cross-eyed.
** Mikami Teru, one of the most psychotic of the Kiras, also sports one of these on occasion.
** The Death God Ryuk also has one permanently etched to his face, along with MoreTeethThanTheOsmondFamily. Light showed what a badass he is when he only was seriously freaked out for a few seconds, when Ryuk spontaneously appeared in his bedroom.
* ''Manga/{{Naruto}}'':
** Gaara displays [[http://images2.wikia.nocookie.net/naruto/images/9/9c/Armor_of_Sand.jpg a particularly frightening one of these]] during his fight with Rock Lee during the Chuunin Exams, after Lee knocks off the sand armor covering his face.
*** It gets worse. Apparently he has that expression ''24/7''. It's only hidden by the sand armor.
** During particularly gruelling battles, Naruto (or rather the Kyuubi displays this, most notably when Sasuke talks to the Kyuubi in Naruto's mind).
** Naruto also (by himself) displayed ''two'' {{slasher smile}}s in the 101st episode of the anime. And some of the smiles he makes when he's about to do (or just finished) a prank can have traces of this.
*** [[spoiler:Dark Naruto]] does this {{Perpetual| Smiler}}ly
** Sasuke wears one before [[spoiler:stabbing through Karin to get Danzo]]. '''[[http://www.manga2u.me/Naruto/480/15/ RUN.]]''' He makes quite a few other ones after that, up until [[spoiler:Naruto tells him they'll both die if they fight]] after which he goes back to a more focused look.
*** Chapter 574: Sasuke shows another. And it is creepy. [[http://www.mangareader.net/naruto/574/15 Just look.]]
** And here's another exemplary performance from '''[[http://www.manga2u.com/Naruto/97/13/ Gaara.]]'''
** This is Orochimaru's and Hidan's default expression.
** Zetsu seems to have this whenever he's battling someone.
** Also, [[spoiler: Dark Naruto]] has this as his default expression.
** Kisame. The only times it usually leaves his face is when he's using a jutsu and has to expel water from his mouth.
** Kabuto gains one after he [[spoiler:absorbs Orochimaru's DNA.]]
** Sakura gets one in a comedic fashion after Konohamaru insults her.
** The normally-stoic Madara Uchiha instantly develops an [[http://images2.wikia.nocookie.net/__cb20130423163014/naruto/images/e/e9/Insane_Madara.png epic]] one when he feels the First Hokage's chakra. Between him, Sasuke, and Itachi, it looks like terrifying expressions are just another part of the BigScrewedUpFamily. [[spoiler:Sadly, the upcoming anime version, seen in the opening credits of Shippuden episode 357, does not do his slasher smile justice. The manga is ''far'' creepier..]]
*** I stand corrected: the actual anime episodes version does do it justice! WOW!
** [[spoiler:In Chapter 677,as Madara activates the Infinite Tsukiyomi,we get the wonderful picture of [[http://img2.wikia.nocookie.net/__cb20140521181116/naruto/images/5/5f/Kaguya_Moon_Eye_Plan_Complete.png Kaguya gazing over the world with the moon as her Third Eye.]] ]]
* ''Manga/DGrayMan'''s Tyki Mikk will do this sometimes. This is a sign that he's [[BeatStillMyHeart about to pluck out your heart]]. The [[BigBad Millennium Earl]] is a cross between this, a StepfordSmiler, and a MonsterClown with his perpetual huge, cheery, and absolutely ''horrific'' grin. In fact, every single member of the Noah family seems to do this occasionally.
** Which now includes the Fourteenth, which is downright disturbing considering [[spoiler: [[TomatoInTheMirror his host is]] Allen Walker. Seriously, who expected the kid to ''ever'' look like [[http://www.mangareader.net/210-41035-14/dgray-man/chapter-189.html this]]?]]
*** And now [[spoiler: Allen]] doesn't even need the 14th Noah [[http://www.mangareader.net/dgray-man/204/15 to do this.]] Somehow, he manages to make such smiles ''even worse.''
** And the when the Earl is pissed off, the preexisting smile goes [[SerialEscalation so far off the deep end]] that hiding under the bed begins to seem like a very attractive option. [[http://www.mangareader.net/210-15225-12/dgray-man/chapter-134.html Meep?]]
** For someone who doesn't smile very often (or only smirks), [[http://www.manga2u.com/D.Gray-Man/97/17/ Kanda]] seems just too creepishly happy when the room collapses on him and everything turns into empty space in the Ark. When he comes back, he starts his day by arguing with Allen rather than thinking about how he could've died.
** Road Kamelot does this sometimes as well too, especially when she starts to get too much fun out of tormenting the main characters.
* PerpetualFrowner [[EvilCounterpart Vicious]] from ''Anime/CowboyBebop'' rarely smiles. This only makes it spookier when he flashes a particularly chilling slasher smile right as he's picking up the AntiHero lead ''[[NeckLift by the neck]]'' and ''throwing him through a stained glass cathedral window''.
** Tongpu from "Pierrot Le Fou" sports one throughout the episode.
* Shonen Bat/Lil' Slugger from ''Anime/ParanoiaAgent''.
* Joshua Christopher of ''Manga/ChronoCrusade'' has a tendency to smile like this, thanks to the demon's horns on his head driving him insane.
* Shark Fujishiro from ''Manga/SetoNoHanayome'' often pulls off a lot of these right before trying to eat Nagasumi.
* [[http://static.tvtropes.org/pmwiki/pub/images/DrossSlasherSmile.jpg Drosselmeyer's smile]] in ''Anime/PrincessTutu'' would almost seem like a CheshireCatGrin if it wasn't for the fact that he's [[WithGreatPowerComesGreatInsanity stark raving mad]] and takes pleasure out of people's suffering.
* Iwao Washizu from ''Manga/{{Akagi}}''. The smile gets wider and wider the more time he's on screen.
* The [[QuirkyMinibossSquad Numbers]] {{Cyborg}} Due from ''MagicalGirlLyricalNanoha'' whenever she goes for the kill, which is almost every scene she's in.
** [[http://mangafox.me/manga/mahou_shoujo_lyrical_nanoha_strikers_the_comics/c010/19.html Nanoha and Signum]] when they got [[BloodKnight carried away]] during a tactical exhibition.
** Also [[MadScientist Dr. Jail Scaglietti]] in ''Anime/MagicalGirlLyricalNanohaStrikerS''.
** Another one, coming from Force, is Cypha of Huckebein. The number of times her smiles ''weren't'' this kind could be counted on one hand... if there were any to count. The only other expressions she exhibits are either stoicism or [[OhCrap being scared shitless from underestimating her opponent]].
* Riful from ''Manga/{{Claymore}}'' shows one when [[spoiler: she first encounters the Abyss Feeders]]. Made creepier by the fact that [[spoiler: there's a large bite out of her head]].
** Ophelia wears one as her usual facial expression because, well, she's what happens when you give TheOphelia a BFS.
* Warsman, from Kinnikuman, is a cyborg. Predictably, he normally can't smile... unless he's in his batshit psychotic personality, in which case he sports the [[ExactlyWhatItSaysOnTheTin Warsman Smile.]] He did use it once, while normal, to catch an arrow in his mouth, though.
* With ''Manga/GetterRobo'', it'd be easier to list the characters who ''don't'' have one of these plastered on their faces most of the time. Ryoma in particular seems to have this as his natural expression.
* [[Manga/AxisPowersHetalia Russia]] signature move when he's not being a StepfordSmiler or wearing a PsychoticSmirk.
** Japan imagines Italy pulling one in the strip where he makes binoculars to read people's thoughts. "I'll touch the back of your head to my heart's content", indeed.
* Even a nice guy like Monkey D. Luffy of ''Manga/OnePiece'' gets one of these, in the 8th opening for the show after landing on a marine ship.
** Zoro does this often too, which is suitable for a character who is often accused of being insane…or a demon.
** Gecko Moria has a permanent one, but it's most apparent during his VillainousBreakdown.
** Donquixote Doflamingo has this as his default look, appropriate for what seems to be One Piece's counterpart to TheJoker.
** [[EvilRedhead Eustass Kidd]] sports one almost all the time, Funnily enough, his face even looks quite similar to the Joker, but even he isn't quite as psychotic as Doflamingo.
** Blackbeard has had a few.
** This happens to the Straw Hats (minus Luffy and Nami) when Oars has his horns stuck to the ground and unable to move. [[http://www.youtube.com/watch?v=KYa9SOuyowE Cue the Straw Hats' slasher smiles]] and a nonchalant, epic, off-screen beatdown of Oars.
** Much like the Oars example, Luffy, Robin and Zoro get slasher smiles (and GlowingEyesOfDoom in the anime) when they reach the cold side of Punk Hazard and see centaurs wearing warm clothes.
** CreepyChild Sugar gets one of these in Chapter 758 when she goes after Luffy.
* ''Manga/VinlandSaga'': Thorfinn, when he does smile. Thorkell's is more of a Slasher Grin, with a big thumbs up thrown in there.
* Being possibly the [[AxCrazy craziest]] [[PsychoForHire bastard]] in the series, ''LightNovel/{{Baccano}}'s'' Claire Stanfield has a [[http://img.photobucket.com/albums/v44/Dragynstorm/Baccano15/Baccano15_129.jpg warehouse]] [[http://img.photobucket.com/albums/v44/Dragynstorm/Baccano15/Baccano15_122.jpg full]] [[http://img.photobucket.com/albums/v102/Ensuing/Baccano9/Baccano_16.jpg of]] [[http://img.photobucket.com/albums/v102/Ensuing/Baccano9/Baccano_37.jpg psychotic]], [[http://img.photobucket.com/albums/v102/Ensuing/Baccano9/Baccano_28.jpg blood-soaked]] [[http://img.photobucket.com/albums/v102/Ensuing/Baccano_54-1.jpg grins]] [[http://img.photobucket.com/albums/v102/Ensuing/Baccano12/Baccano_50.jpg and]] [[http://img.photobucket.com/albums/v44/Dragynstorm/Baccano16/Baccano16_88.jpg smirks]] to put to use. Not to say that [[http://img.photobucket.com/albums/v102/Ensuing/Baccano_39.jpg Ladd]], [[http://img.photobucket.com/albums/v102/Ensuing/Baccano10/Baccano_4.jpg Czeslaw]], and [[http://img.photobucket.com/albums/v102/Ensuing/Baccano14_26.jpg Graham]] don't get their fair share.
* Kurogane from ''Manga/{{Tsubasa Reservoir Chronicle}}s'' often does this. In fact, that's the only time he ''ever'' smiles.
* Michiko from ''Anime/MichikoToHatchin'' sports one right before she breaks through a police roadblock.
* In ''Manga/SoulEater'', Maka gets one of these when she [[spoiler: [[http://randomc.maximum7.net/image/SOUL%20EATER/SOUL%20EATER%20-%2021%20-%20Large%2007.jpg goes completely nuts while fighting Chrona]]]].
** Medusa, whenever she makes [[http://randomc.animeblogger.net:8000/image/SOUL%20EATER/SOUL%20EATER%20-%2022%20-%20Large%20Preview%2003.jpg one of her]] [[http://randomc.maximum7.net/image/SOUL%20EATER/SOUL%20EATER%20-%2031%20-%20Large%2012.jpg crazy faces]].
** Stein on [[http://randomc.maximum7.net/image/SOUL%20EATER/SOUL%20EATER%20-%2029%20-%20Large%2014.jpg several]] [[http://randomc.maximum7.net/image/SOUL%20EATER/SOUL%20EATER%20-%2018%20-%20Large%2013.jpg occasions]], but particularly when [[http://randomc.maximum7.net/image/SOUL%20EATER/SOUL%20EATER%20-%2023%20-%20Large%2022.jpg he goes nuts while fighting Medusa]].
*** Additionally, his appearance during the anime's second opening has him sporting one as well.
** Asura gets them pretty often, being insane and all. [[http://randomc.maximum7.net/image/SOUL%20EATER/SOUL%20EATER%20-%2023%20-%20Large%2033.jpg They're]] [[http://randomc.maximum7.net/image/SOUL%20EATER/SOUL%20EATER%20-%2042%20-%20Large%2026.jpg pretty]] [[http://randomc.animeblogger.net:8000/image/SOUL%20EATER/SOUL%20EATER%20-%2050%20-%20Large%2036.jpg impressive]].
** Oh, and [[http://randomc.maximum7.net/image/SOUL%20EATER/SOUL%20EATER%20-%2020%20-%20Large%2024.jpg the Imp]]. It's even worse [[http://randomc.animeblogger.net:8000/image/SOUL%20EATER/SOUL%20EATER%20-%2050%20-%20Large%2003.jpg when he's in Soul's body]].
** They seem to be the stock expression for mad characters; it's [[http://www.onemanga.com/Soul_Eater/69/01/ weird]] to see ''Justin'' sporting one, especially with that visor obscuring his eyes.
** Even the Moon has one in this series.
** Even the Woobie, Crona, has a few!
* The various {{Blood Knight}}s in ''Manga/SamuraiDeeperKyo'' often have this in their faces while really enjoying a fight. Top dog Onime no Kyo combines it with RedEyesTakeWarning ''and'' the GlowingEyesOfDoom to create a visage unparalleled in its ominousness.
* ''Anime/{{Pokemon}}'':
** Jessie, in her crazy moments. [[http://www.youtube.com/watch?v=OTHp22vLBpo Here's an example]] (Tracey Gets Bugged, episode 97)
** If a Pokémon has sharp teeth and isn't UglyCute, expect its grin to look like this.
* Gyororo from ''Manga/SgtFrog''.
** We also see Keroro with a manic grin on his face when he learns Natsumi is [[WhyDidItHaveToBeSnakes afraid of slugs]].
* ''Manga/MahouSenseiNegima'' has [[PsychoLesbian Tsukuyomi]] doing one of these when she fights Setsuna.
* Two [[PersonOfMassDestruction teens of mass destruction]] of ''Manga/OutCode'' lapse into this when their real personalities are exposed (PsychoForHire and {{Manipulative B|astard}}itch, respectively). Interestingly, both of these characters were [[IllGirl frail-looking girls]]. The MadScientist who gave them their powers seems to owe his look to [[Franchise/SailorMoon Dr. Tomoe]].
* [[Manga/MajinTanteiNougamiNeuro Neuro]] has a psychotic grin most of the time, and ''then'' he reverts to a parrot-headed-EldritchAbomination. There's also the twisted, insane looks of the criminals as they confess.
* Grelle Sutcliffe the {{Shinigami}} from [[Manga/BlackButler Kuroshitsuji]] has one of these. Made even better and creepier by the fact [[{{Transsexual}} she]] had just finished murdering someone a few seconds ago and is covered from head to toe in blood. Too bad it isn't really seen again after this, because she's too busy being a goofball, playing with safety scissors. Yes, really.
** The smile [[http://www.kuroshitsujimanga.com/57/15/ remains]] [[http://www.kuroshitsujimanga.com/57/16/ in]] [[http://www.kuroshitsujimanga.com/58/32/ the manga]], where she was PutOnABus (which then [[TheBusCameBack came back]]), rather than the above-mentioned VillainDecay.
** And in the second season, [[CreepyChild Alois]] likes wearing either this or a PsychoticSmirk. The most notable example is the one he wears right before [[EyeScream stabbing Hannah's eye out with his fingers]].
* [[SuperOCD Chiri]] gets one completely out of the blue at the end of an episode of ''Manga/SayonaraZetsubouSensei''. Its utterly random appearance combined with its [[MoreTeethThanTheOsmondFamily large number of teeth]] made it horror in its purest form.
* ''Anime/YuGiOh'': Yami Marik constantly sports one.
** Yami Bakura often has one as well, even moreso during the final arc.
** Not so much in the anime, but during the Death-T arc in the manga both Kaiba brothers each get a couple at the prospect of killing Yugi and his friends.
*** Seto actually sports one a lot in the manga, especially when he's about to crush an opponent during a duel.
** Dartz gets one when [[spoiler: he uses the Seal of Orichalcos in the final battle against Yami Yugi and Kaiba.]]
** In the early chapters of the manga when Yami Yugi's character was a lot darker and you weren't really sure if he was truly a good guy or not, [[http://ravegrl.files.wordpress.com/2009/11/littlekuriboh_reviews_yu-gi-oh_1.jpg?w=550 he almost always sported one]]... especially when he declared to a rival that they would undergo a "penalty game" if they lost to him.
** ''Anime/YuGiOhGX'': Hell. Kaiser. Ryo.
** Also from GX, Saiou/Sartorious at first only sports a PsychoticSmirk but graduates to this as a sign that he has been completely taken over by The Light.
* As a NeatFreak, Ryuuji from ''LightNovel/{{Toradora}}'' gets one whenever he ''cleans''. As in, dirt and dust and mold. Combined with his permanent death glare, he looks like he's rejoicing in the thought of committing genocide on entire societies of dust mites and mold colonies. There's a brief shot of one right in the opening theme.
* [[VisualNovel/UminekoNoNakuKoroNi Beatrice, the Golden Witch]] has a rather good one, completely with [[FangsAreEvil not-so-]]CuteLittleFangs. It's a particularly common expression when she's trolling Battler.
** Also, Maria, when she's in CreepyChild mode. Which, in the anime, is ''[[{{Narm}} ALL THE TIME]]''.
* Gauron from ''LightNovel/FullMetalPanic'' usually cracks one of these whenever he's not wearing his PsychoticSmirk. [[MemeticMolester HE WANTS TO RAPE YOU!!!]]
* ''Manga/AngelDensetsu'''s Kitano.
** Subverted as that's his ''default expression'' and he's actually one of the [[AllLovingHero nicest character in the history of fiction]]. For others however, nightmare indeed.
* Hiruma Youichi from ''Manga/{{Eyeshield 21}}'' has one of these, aided by his fang-like teeth and his habit of constantly carrying large guns when not on the field. In fact, he does it so often that he scares his teammates when he DOESN'T have a slasher smile, and uses it to his advantage against his opponents.
* Killua from ''Manga/HunterXHunter'' gets [[http://www.onemanga.com/Hunter_X_Hunter/21/13/ one]], holding not a knife, but the [[BeatStillMyHeart still beating heart]] of his latest victim.
* At the end of the ''Anime/WeissKreuz'' [=OAV=], Ken Hidaka perfectly calmly prepares to kill the man who tried to set up the deaths of his entire team. Then he actually pulls the trigger.
* ''Anime/CodeGeass''
** [[MagnificentBastard Lelouch]] right after he successfully orders a collective suicide with his handy-dandy new [[HypnoticEyes geass]]. Being [[DespairEventHorizon only]] [[RoyallyScrewedUp semi]]-[[EvilLaugh crazy]], he otherwise reserves it only for special occasions (such as having just added another few digits to his kill count).
** This is also the apparent default expression for any Geass thralls ordered to kill someone. [[FridgeHorror Including themselves]].
*** V.V. has one during most of the time he's piloting the Siegfried against the Black Knights during their attack on the Geass Order.
* Several characters in ''Manga/RosarioToVampire'' pull this off nicely, but the best example would be [[OrdinaryHighSchoolStudent Aono Tsukune]] in his "[[SuperpoweredEvilSide Ghoul]] [[AxCrazy Form]]." Bonus points for grinning at an attack just inches from his face and then proceeding to [[CurbStompBattle beat the shit out of everyone in front of him]].
* In ''Manga/KimiNiTodoke'', when Sawako Kuronuma tries to smile it usually look like [[http://www.mangareader.net/280-19779-9/kimi-ni-todoke/chapter-0.html this]].
* ''VisualNovel/OokamiKakushi'': The maid in the second half of episode 12 advances on Hiroshi while simultaneously unbuttoning her uniform top and flashing her best smile.
** Issei indulges in this as well.
** And in episode 11, [[spoiler: whenever Sakaki, now having [[AxCrazy gone off the deep end,]] actually ''does'' smile, he alternates between this, and SmugSnake smirks. Naturally, the latter is a little less creepy.]]
* Lots of characters in ''Manga/PandoraHearts'' pull one of these at times. Especially the Baskervilles and Will of the Abyss.
** Break does this at times too.
* ''Anime/{{Gankutsuou}}'': The eponymous Count wears a rather terrifying example of this when everything is going according to plan (which usually involves a humiliating and/or painful death).
* ''Manga/DragonBall Z'': Zarbon manages one that's ''just'' twisted enough to be freaky, just before transforming into a... [[OneWingedAngel rather unattractive salamander-looking thing]].
** Captain Ginyu breaks into one [[spoiler: right before he uses his body change ability to switch bodies with Goku]].
** In the filler "Garlic Jr. arc" in ''Anime/DragonBallZ'', when Piccolo is infected with the Black Water Mist and turned evil the first thing he does to let us know this to break into one of these smiles. [[spoiler: Turns out he's actually faking being infected though]].
** Vegeta gets one after getting possessed by Babidi and becoming [[http://images4.wikia.nocookie.net/__cb20101116103616/dragonball/images/a/af/Vlcsnap-2010-11-08-14h01m42s212.png Majin Vegeta]].
*** Even before that, he sports [[http://i1.ytimg.com/vi/7O5_dtPiWvo/mqdefault.jpg one]] after he kills Jeice.
** Super Buu and Kid Buu smile like this by default since they're both textbook definitions of AxCrazy characters (or forms in this case). Frieza occasionally breaks out this smile too, a good example being when he shot Piccolo through the chest with his death beam.
* In ''Manga/ZatchBell'', we have [[http://www.onemanga.com/Zatch_Bell/158/18/ this little beauty]] from Zophise.
* Haguro and Ryuuko of ''Manga/WolfGuyWolfenCrest'' revel in this.
* [[AxCrazy Yuno]] [[{{Yandere}} Gasai]] of ''Manga/MiraiNikki'' has a combination of one of these and a ManicPixieDreamGirlStare on her face on a more or less permanent basis. She is... not well.
** Minene also sports a kill grin as her default expression, though unlike Yuno, she keeps her cool most of the time.
* This is Koko Hekmatyar's default facial expression in ''Manga/{{Jormungand}}''. Though she rarely does her own dirty work, the fact that she is a [[ArmsDealer dealer of death]] makes this appropriate.
** Also her older brother, Kasper and his bodyguard Chiquita.
* Ryuuhei Sawamura and Bryan Hawk of ''Manga/HajimeNoIppo''.
* One episode of ''Manga/KyouNoGoNoNi'' mentions how nobody remembers seeing EmotionlessGirl Kazumi Aihara ever smile. If the first episode is any indication, it's because her smiles end up as one of these...
* Half the cast of ''Manga/KarakuridoujiUltimo'' probably has one. [[http://www.dm5.com/Comic/MH77/Comics-77321_e7771fa0_page-32.htm It]] [[http://www.dm5.com/Comic/MH64/Comics-64519_d1d1c0a8_page-14.htm doesn't]] [[http://www.dm5.com/Comic/MH69/Comics-69814_75865429_page-17.htm matter]] [[http://www.dm5.com/Comic/MH79/Comics-79388_f30050df_page-36.htm who]] [[http://www.dm5.com/Comic/MH82/Comics-82517_65441211_page-7.htm it]] [[http://www.dm5.com/Comic/MH83/Comics-83476_f3070f20_page-12.htm is.]] Piss off anybody and you'll be greeted with any of these expressions.
* [[TheBerserker Shizuo]] [[HairTriggerTemper Heiwajima]] of ''LightNovel/{{Durarara}}'' is fond of sporting these right before he's about to hurt someone.
* In ''Manga/{{Monster}}'', the unspeakably evil Johan Liebert, commits MindRape on a former cop who had killed a boy while drunk and is trying to atone, playing on his guilts. He eventually asks him how he would look his estranged daughter in the eyes and then realizes that he's got him, and then makes one of the most unsettling and terrifying smiles imaginable before asking "[[DrivenToSuicide well Richard, how about a drink?]]"
* The AntiHero protagonist of ''Anime/ShamanicPrincess'' directs one at her rival after completing her first TransformationSequence, made even creepier by her weird eyes. It's one of your first clues that [[DarkerAndEdgier this is not your average]] MagicalGirl anime.
* Shani Andras and Auel Neider of ''Anime/MobileSuitGundamSEED'' and ''Anime/MobileSuitGundamSEEDDestiny'' wear these as their normal expression. Their fellow {{Super Soldier}}s Orga Sabnak, Cortho Bauer, and Sting Oakley have also been known to crack them out from time to time.
* Speaking of ''Franchise/{{Gundam}}'', Desil Galette from ''Anime/MobileSuitGundamAge'' sports a horrific one when he casts off his cute child persona at the end of Episode 13. Seriously, you wouldn't imagine a ''seven year old'' to look like '''[[http://1.bp.blogspot.com/-IWY-LG-jmfg/TwlbgMeS3TI/AAAAAAABwJc/g2FQ6GUsTu8/s1600/67.jpg this,]]''' would you?
** [[spoiler: And if you know that Desil's alive in the Second Generation, [[BlatantLies don't you worry!]] [[FromBadToWorse THEY GET]] '''[[http://2.bp.blogspot.com/-qCuRvMd5Vdk/T0o_JO_HiNI/AAAAAAACE9Q/aqoyxSiGRHc/s1600/7.jpg INFINITELY]] [[http://jan.2chan.net/dec/18/src/1330244651193.jpg WORSE.]]''']]
** Thought Desil was the only one who could smile so horrifically? [[spoiler:Arabel Zoi]] [[http://gundam.wikia.com/wiki/File:Alabel-141.png has something for you...]]
* In [[Manga/KareKano His And Her Circumstances]], there are instances where Yukino Miyazawa sports one of these.
** In the anime Yukino gets an epic *series* of different slasher smiles in a rampage after [[spoiler: Tsubasa]] presses her BerserkButton.
* Kohta Hirano, from ''Manga/HighschoolOfTheDead'', often dons one when fighting "Them". Contradicts nicely with his [[BewareTheNiceOnes usual personality]].
* [[{{Yandere}} Mimi]] of ''Manga/LovelyComplex'' wears one of these when threatening Risa.
* Kagura from ''Manga/{{Gintama}}'' [[http://gallery.minitokyo.net/view/418521 gets one]] when her Yato side kicks in harder than she can control.
** Also her brother, Kamui.
** Besides the above examples, this trope is usually PlayedForLaughs.
* Sayaka from ''Anime/PuellaMagiMadokaMagica''. After being pushed past her DespairEventHorizon she is seen smiling and {{laughing|Mad}} while [[NoKillLikeOverkill tearing into a witch with her sword]]. While covered in blood. While her best friend watches on. [[BreakTheCutie Poor girl.]]
* ''Manga/TasogareOtomeXAmnesia'' gives us the horror that is [[http://static.zerochan.net/full/15/05/1040265.jpg Shadow Yuuko.]]
* The first episode of ''Anime/{{Persona 4}}'' has Yu with a (completely heroic and yet still disturbing) slasher smile on his face while summoning Izanagi for the first time.
* In the 10th episode of ''[[VisualNovel/PhantomOfInferno Phantom ~Requiem for the Phantom]]'', when Reiji begins chasing after Scythe Master, he starts breaking into [[http://i19.photobucket.com/albums/b162/MisterC/Phantom/cap178.jpg this]] twisted grin. Combined with his creepy laughing and [[http://www.youtube.com/watch?v=rE8IYTMzzTs&feature=channel&list=UL this]] little piece playing in the background and the whole thing easily goes into Nightmare Fuel territory.
* Manhwa/JackFrost is the embodiment of this trope. The wider his smile, the bloodier things get. [[BloodKnight And things get pretty damn bloody.]]
* The Master of Synapse from ''Manga/HeavensLostProperty''.
* Akura-ou from ''Manga/KamisamaKiss,'' being a PsychopathicManchild, has this as his default facial expression. One of the main protagonists, Tomoe, also tends to sport one when he is about to do something nasty. [[spoiler: Small surprise since he used to be Akura-ou's partner in crime.]]
* Mahiro Fuwa in ''Manga/ZetsuenNoTempest'' seems to have an emotional spectrum that ranges from 'indifferent' to [[http://i.imgur.com/OvtVSVB.jpg this]]. Frighteningly enough, [[spoiler:he's regarded as far less of a threat than his [[StepfordSmiler best friend]].]]
* Tsuchiya gets one in ''Manga/{{Holyland}}'' chapter 144 just before he turns a fight around.
* In ''Manga/AttackOnTitan'', [[spoiler:Annie]] smiles like this [[spoiler:when she is correctly accused of being the Female Titan. Made even creepier since this is the only smile (or any other expression other than indifference) she's given so far in the series]].
** This is also the default expression for some of the titans due to the way the skin on their faces has stretched.
** [[spoiler:Armin]] of all characters, pulls one while [[spoiler: lying to Bertholt about how Annie is being subjected to torture.]] It's actually kind of jarring.
** In chapter 51, [[spoiler:Erwin]] sports one after finding out that [[spoiler: titans were once humans]]. It was so unnerving that even ''[[TheStoic Levi]]'' was disturbed by it.
** Armin also pulls one of [[http://rebloggy.com/post/shingeki-no-kyojin-mikasa-ackerman-snk-spoilers-armin-arlert-shingeki-no-spoiler/82223194331 these]] in the second OVA when Jean suggests stealing meat from the commander's office. Makes you wonder how far off the deep end he truly is, doesn't it?
* Just about everyone in ''Manga/{{Drifters}}''. It could even be said the heroes do it more than the villains.
* Kunitoshi Joukyuu, the protagonist of ''{{AIKI}}'', loves using these.
* ''Anime/QueensBlade'': Right before she blows up a part of Vance Castle in episode 1 in an attempt to kill Reina, [[PsychoticManchild Melona]] flashes a grin that's all teeth and malice and WAY too big for her face.

[[folder: Card Games]]
* [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=218040 This]] fine example from [[TabletopGame/MagicTheGathering New Phyrexia]].
[[/folder]]

[[folder: Comic Books]]
* The "American" vampires in ''ComicBook/AmericanVampire'' do these really, really well.
* SelfDemonstrating/TheJoker from ''Franchise/{{Batman}}'' had this expression [[FrozenFace glued on his face]]. His "Joker Venom" induces the expression in those exposed to it.
** The literary example, ''Literature/TheManWhoLaughs'' by Creator/VictorHugo, which is commonly cited as inspiration for SelfDemonstrating/TheJoker, involves a man whose face is horribly mutilated so that he cannot stop smiling and how his psyche is twisted by this. In order to maintain the grin throughout the movie, actor Creator/ConradVeidt had to get metal hooks in his mouth to pull back his cheeks. Nevertheless, the character is a really nice guy.
** In Creator/FrankMiller's ''Comicbook/{{All Star Batman|AndRobinTheBoyWonder}}'', the Dark Knight himself has one in both his costumed and civilian identity, especially when thinking about his young ward, age 12. {{Squick}}.
* AntiHero example: The Midnighter, in ''Comicbook/TheAuthority''. He [[SociopathicHero loves his job]] and he isn't afraid to show it in the scariest manner possible.
* [[Comicbook/{{X-Men}} The Juggernaut]] enjoys his role as an unstoppable engine of destruction.
* Johnny of ''Comicbook/JohnnyTheHomicidalManiac'' would usually have one while torturing or killing victims. Mr. Eff and Psychodoughboy had permanent ones because Johnny painted them onto their faces.
* {{Comicbook/Judge D|redd}}eath does this all the time as well. Mostly because his lips have rotted off.
* In Franchise/SpiderMan, Carnage's alter ego Cletus Kasady has one of these.
** In fact, symbiotes appear to have some sort of demonic smile on their faces sometimes.
** In the classic ''Spider-Man vs. Wolverine,'' there's a scene where they're duking it out in an East German graveyard. Spider-Man thinks, "I'm hitting him hard enough to wreck cars... and I can't get him to stop ''smiling...''"
* Mystique in the "Wolverine" story arc "Get Mystique"; just before their final climactic confrontation she strips naked, festoons herself with weapons, puts on a slasher smile and says, "Coma and GET me, Lover!"
* Franchise/WonderWoman villain Doctor Poison has a big creepy smile, pulled up by metal hooks she slips into the corners of her own mouth.
* From the ''Comicbook/TheSandman'' series:
** The Corinthian has ''three'': [[spoiler:he has devouring mouths instead of eyes behind his shades]]. Fitting, since he's the ''eidolon'' (the word ''eidolon'' being especially apt here: it connects strongly to concepts such as delusion, idol, spirit, or bogeyman) or [[spoiler:archetype dream that inspires and is inspired by {{Serial Killer}}s]].
** George in "A Game of You".
* EvilErnie. And maybe his button.
* One of the last things you want to see is [[UltimateMarvel Ultimate Hawkeye]] covered in the blood of the squad you sent to subdue him, holding their weapons and grinning into your security camera telling you, [[TranquilFury "Run"]], when you are part of the group responsible for his family's murder. Unfortunately for you, it ''is'' the one of the last things you're going to see.
* [[http://upload.wikimedia.org/wikipedia/en/d/df/Bullseye5.jpg Bullseye.]] Yeah, you see that space where he's missing a tooth? That's cause he killed a guy with it.
* Subverted in an issue of ''Franchise/GIJoe''. Formerly masked gunmen hold a family hostage in a remote house with the result being the authorities are not sure at first who are the hostages and who are the hostage-takers. One of them seems to be grinning maliciously all the time and the footage they have of the masked rampage shows them all grinning like maniacs while gunning down innocent people. So obviously the one with the constant grin is one of the bad guys? Wrong, he's the father of the innocent family caught in the middle, and a veteran who had suffered permanent damage to his facial muscles during active military service.
* Kid Miracleman from the [[Comicbook/{{Miracleman}} series of the same name]] is constantly depicted with this facial expression. The scariest example is probably from the cover of Issue #15 (which can be found in the ImageLinks)- truly horrifying just from the sheer inhumanity of that grin.
* [[ComicBook/SamAndMaxFreelancePolice Max's]] default expression.
* Marv from ''Comicbook/SinCity'' makes them all the time.
* Very often shown by Spider Jerusalem from ''Comicbook/{{Transmetropolitan}}''.
* Grimjack sports one whenever he is in a fight. The smile is an involuntary tick that he developed as a child gladiator where he was known as "The Grinner." Also, combat is the only time you ever see him smiling.
* Pinkie Pie does a face like this in [[http://fav.me/d5mjno7 page 9 of Issue 1]] of ''ComicBook/MyLittlePonyFriendshipIsMagicIDW'' complete with a "cut/slit throat" gesture.
* The magically created [[Franchise/{{Batman}} Batzarro]] is the opposite of Batman in every way he can be - so since Batman is grim and serious, Batzarro has a wild, fanged smile (and no eyes, making his smile freakier).

* In the '''WesternAnimation/JackieChanAdventures'' fic ''Fanfic/QueenOfAllOni'', Jade gives one to her {{Jerkass}} former classmate Drew.
* [[http://www.fanfiction.net/s/7609018/1/Lets_Do_The_CaramellDansen Let's Do The Caramelldansen]] has the most brilliant description ever. "So Vexen smiled, and it was... a purely evil smile. A MANIACLY evil smile. Take every synonym for 'evil', put them before the word 'smile', and you may even get Vexen's smile. It's hard to comprehend how truly terrifying the smile was. But if Hitler and Big Brother had a child, and that child had a child with Satan, and that child had a child with the child of Voldemort and Darth Vader, and that child were to smile, it would probably the closest you could get to how awfully evil Vexen looked at that moment. (Sorry for that image, people) It could make a serial killer cry." That is how the smile was described, scary huh?
* When the killer [[spoiler: Drew]] is revealed in the ''Series/HannahMontana'' story ''I Didn't Sign Up For This'', the first thing she does is [[YouHaveOutlivedYourUsefulness shoot her]] [[TheDragon accomplice]] with what is described as "a creepy smile" on her face.
* In ''Fanfic/FrozenHearts'', Prince Harken gets one as he's considering [[ATasteOfTheLash whipping]] [[{{Disney/Frozen}} his younger brother Hans]].

* The Other Mother in ''WesternAnimation/{{Coraline}}'' does this, particularly towards the end of the movie.
* ''WesternAnimation/CorpseBride'' has Barkis Bittern use this constantly cause he's an evil bastard and some of the dead people when they go to the land of the living.
** Barkis's smile seems more of a PsychoticSmirk -- but the rotting dead's grins could definitely qualify, at least when they first arrive.
* Ratigan of ''Disney/TheGreatMouseDetective'' sports a huge one after he's convinced he's [[NoHoldsBarredBeatdown mauled Basil to death.]]
* Ursula of ''Disney/TheLittleMermaid'' does this a few times during the final battle. Her alter-ego Vanessa even pulls one off when she throws a pin at a mirror with enough force to knock it back while gloating about her inevitable victory.
* Gaston sports one at the start of his fight with the Beast in ''Disney/BeautyAndTheBeast''. And yet another after stabbing the Beast in the side.
* In ''WesternAnimation/{{Ratatouille}}'', Colette's opening KnifeNut sequence to her mentorship of Linguini (and, unknown to her, Remy) is especially scary when she takes on this expression with her question because you know Linguini won't be able to answer it properly.
* The sirens in ''WesternAnimation/SinbadLegendOfTheSevenSeas'' give Marina one of these.
* When he [[spoiler: killed Yamagata]], Tetsuo let out a rather creepy smile. ''Manga/{{Akira}}'' [[http://data.whicdn.com/images/9393521/1175838150_f_large.jpg?1304363970 has another good example of when he did this: ]]
* ''Disney/{{Pinocchio}}'': The Coachman during his "They never come back as BOYS!" line.
* ''WesternAnimation/ThePebbleAndThePenguin'': The BigBad Drake constantly sports a Trollface-like smile
* ''WesternAnimation/TomAndJerryTheMovie'': The scene where Doctor Applecheeks steals the ice cream truck.
* Cera in ''WesternAnimation/TheLandBeforeTime'' gives a pretty big slasher smile when she decides upon seeing what is apparently Sharptooth's corpse to use it as ramming practice. However, a few rams in, she soon discovers that Sharptooth was not quite as dead as she originally thought, and just barely managed to survive to tell the tale.
* Ed the hyena (and to a much lesser extent, Shenzi, Banzai, and all of the other hyenas) actually gains this type of smile when [[spoiler: the hyenas all kill [[BigBad Scar]]]] at the end of ''Disney/TheLionKing''.
** Scar gives one himself to Zazu when he points out how unhappy Mufasa will be that he didn't show up for Simba's birth ceremony. After he tells him this (as well as forcing Scar to let a mouse, his ''lunch'', escape), Scar sarcastically states "ooh, I quiver with FEAR!", flashing this smile when he says the last word, and then tries to EAT Zazu! Good thing Mufasa showed up right at that moment.
* Rothbart from ''WesternAnimation/TheSwanPrincess'' gains one of these near the end after he transforms into [[OneWingedAngel The Great Animal]] for the second time.
* The MonsterClown that appears in Toaster's dream sequence in ''WesternAnimation/TheBraveLittleToaster'' has a big one [[FrozenFace glued to its face]].
* In ''WesternAnimation/TheLorax'', at the end of the VillainSong, "How Bad Can I Be", the Once-ler has one after shouting the last lyrics, "HOW BAD CAN THIS POSSIBLY BE?!"
* ''Disney/AtlantisTheLostEmpire'': When [[spoiler: Rourke]] has a pretty awesome and crazy slasher smile when he tries to kill Milo with a fire axe. You can clearly tell the guy has gone batshit insane.
* In ''WesternAnimation/AllDogsGoToHeaven'' after Killer, currently trying to do everything he can to get Carface to spare his life, tells him he has a gun they can use to try and kill Charlie (for good) with, Carface breaks into a wide satanic version. And when I said satanic, I meant that literally--- his face (presumably, we're seeing him from Killer's POV) actually proceeds to transform into an actual devil's.
* [[SinisterMinister Judge Claude Frollo]] from ''Disney/TheHunchbackOfNotreDame'' have a grin [[Franchise/{{Batman}} The Joker]] would be proud of; when he raises his sword to kill Esmeralda and Quasimodo, he believes that he's won, [[NightmareFuel/TheHunchbackOfNotreDame and it shows]].
** He also puts on a brief, but huge and sadistic one shortly after he sets fire to the platform Esmeralda is on when he tries to burn her at the stake.
* In ''Disney/{{Frozen}}'', [[spoiler: Hans has a villainous smile as he raises his sword to kill Elsa.]]
* [[spoiler:Homura Akemi herself]] [[WhamShot very, very briefly]] develops one in ''PuellaMagiMadokaMagicaTheMovieRebellion'' as [[spoiler:Madokami comes down to receive her to heaven.]] It serves as a short and extremely unsettling warning that something's about to go horribly wrong, confirmed about thirty seconds later [[spoiler:when Homura proceeds to hijack Madoka's powers.]]

* Alex from ''Film/AClockworkOrange'', whenever he gets deep into the [[http://www.youtube.com/watch?v=v90KPJ6n4Ew&feature=related old ultraviolence. (forms at around 1:10)]]
* The short horror film ''Smile'' revolves around body-snatching beings with hideous grinning faces. [[http://www.youtube.com/watch?v=CT1Erm2C4iQ It's well worth a watch.]]
* Creator/JimCarrey has done this trope in ''Film/AceVentura Pet Detective'', ''Lemony Snicket's Literature/ASeriesOfUnfortunateEvents'', and ''Film/HowTheGrinchStoleChristmas'' to demonstrate how remarkable his rubberface really is when it comes to expressions.
* Creator/NataliePortman unleashes a blood-curdling one in ''Film/BlackSwan'' while portraying her doppelganger in the bath scene. [[http://www.n-portman.org/gallery/displayimage.php?pid=39951&fullsize=1]]and[[http://www.n-portman.org/gallery/displayimage.php?pid=40208&fullsize=1]]
* The ever lovable late comedian Creator/JohnCandy had this expression on his face in ''Film/UncleBuck'' during the scene where he comes to the bedroom of Tia's "boyfriend" Bug to rescue Tia by drilling a hole through the doorknob, he's also holding a drill and smoking a cigar. Although generally throughout the movie Buck comes out as kind of kooky such as when he asks Tia "How would you like to spend the next several nights wondering if your crazy out of work bum uncle will shave your head while you sleep?" and where he's talking to Tia's boyfriend about burying the hatchet.
--> '''Bug''': "Ever hear of a tuneup? Ah-hee-hee-hee-hee!"
--> '''Buck''': "Ah-hee-hee-hee-hee! Ever hear of a ritual killing? Ah-hee-hee-hee-hee!"
--> '''Bug''': "...I don't get it..."
--> '''Buck''': "You gnaw on her face in public like that again and you'll be one. Ah-hee-hee-hee-hee!"
* In the Tony Jaa movie ''Film/TomYumGoong'', or ''The Protector'', one of the many opponents that Tony faces is a Capoeira fighter, who has just attacked a Buddhist temple full of innocent people, set the place ablaze, and then attacks Tony as soon as he arrives to help. What qualifies "Mr. Fake Eddie Gordo" for this trope is the fact that while he fights Tony, he laughs, taunts Tony, and openly toys with him using feints and false moves.
* ''Film/TheRockyHorrorPictureShow'': Dr. Frank N Furter has one of these right before he [[spoiler:kills Eddie with a pick axe]].
* ''Film/DonnieDarko'', every single time he [[spoiler: sees his giant bunny-friend Frank.]] It's a little creepy, to say the least. No teeth in this one, though.
* In Creator/TimBurton's ''Film/{{Sweeney Todd|TheDemonBarberOfFleetStreet}}'' just after the Pirelli sequence, Sweeney directs one at the Beadle. Scary doesn't even cut it. It's enough to make Jack the Ripper wet his pants. Although, like Donnie above he doesn't bare his teeth, so may overlap with PsychoticSmirk.
* In ''Film/{{Ghostbusters}}'', this, together with [[EvilSoundsDeep a horrifying demon voice]], lets Dr. Venkman (and us) know "There is no Dana, only Zuul."
* [[AxCrazy Mitsuko]] from ''Literature/BattleRoyale'' before killing Megumi. The girl at the beginning of the film (the battle's first female winner) has a seriously creepy one too.
* In ''[[Film/TheAddamsFamily Addams Family Values]]'', circumstances force [[TheSnarkKnight Wednesday]] to... construct... a smile; the result is so horrific it drives other children to tears.
-->'''Amanda:''' She's scaring me!
* The film version of ''Literature/TheManWhoLaughs'' has Creator/ConradVeidt with one of these permanently etched into his face. Considering his best-known role up to that point was [[Film/TheCabinetOfDrCaligari a sleepwalking serial killer]], the character in this film turned out to be [[PlayingAgainstType a good deal more sympathetic]] than one would expect. [[spoiler:His smile was the result of a surgical disfiguration. He was actually a pretty nice guy.]]
* ''Film/MrSardonicus'' took liberal inspiration from the aforementioned ''The Man Who Laughs'' with the [[http://farm3.static.flickr.com/2364/2186924247_5cb2d6583f.jpg?v=0 carved smile]], but the character was much less of a sweet guy than Gwynplaine. It was up to the audience to decide whether he was a villain or an AntiVillain - this being a William Castle film, they were polled, and a different ending would be screened based on whether they thought he should be treated mercifully. They killed him every time, and the mercy ending is probably lost for eternity, assuming it ever existed at all.
* ''Film/NationalLampoonsChristmasVacation'' has Clark Griswald become somewhat unhinged come the end of the movie as his idea of a "perfect Christmas" gradually disappears; his smile, however, stays.
* ''Film/GalaxyQuest'' also makes use of this trope when [[spoiler:Sariss, disguised as Fred, arrives on the command deck to kill off the heroes]]. It's a very well-played OhCrap moment.
* At the end of the third segment of the 1975 made-for-TV movie ''Film/TrilogyOfTerror'' the eponymous "Amelia" crouches down low in an animalistic manner, hiding in the corner with a carving knife. She stabs at the floor with the weapon, grinning ferally and revealing the horrific teeth of the [[CreepyDoll Zuni doll]].
* In ''Film/{{Oldboy}},'' our hero spends 14 years alone in a cell that features a mirror marked with the message "Smile, and the world smiles with you." He practices a smile in the mirror through the years, without any hope or contact with another person, and it becomes quite unsettling. When he's finally released on his RoaringRampageOfRevenge, he has occasions to show off his slasher smile while doing pretty horrible things.
* [[AxCrazy Chester]] gives truly creepy smiles like this in ''Film/{{DOA}}''
* Brandt from ''Film/{{Equilibrium}}''.
* Creator/MeganFox displays one at various times in ''Film/JennifersBody''.[[spoiler: Most notably after she first becomes possessed and when she appears in Needy's vision sitting on top of the chair watching her and Chip have sex.]]
* In ''Film/AttackOfTheClones'', Dooku gives a very mocking, {{troll}}ish slasher smile just before incapacitating Obi-Wan.
* Loki gets frighteningly good at these during ''Film/TheAvengers'' to reflect his more...[[JumpingOffTheSlipperySlope unhinged]] mental state since ''Film/{{Thor}}''.
** In the stinger, [[spoiler: Thanos has a happy thought. So he smiles.]]
* The mask of the killer ''Film/{{Smiley}}'' sports a stitched and bloody looking one.
* A ''velociraptor'' actually achieves one in ''Franchise/JurassicPark''. As it watches two children flee from a kitchen, it bares its front teeth in such a way that it ''actually'' seems to be grinning at them.
* Castor Troy from ''Film/FaceOff''. When Creator/NicolasCage becomes Sean Archer, he makes one HELL of a slasher smile after taking drugs while seeking refuge at Dietrich's apartment.
* ''Film/ManOfSteel'': Superman, of all people, in battle. So, probably for the best that he rarely smiles the entire film. He does [[WhenHeSmiles smile normally]] "at ease".
* ''Film/RaidersOfTheLostArk''. Toht, even when Dr. Jones threatens to destroy the Ark with a panzerfaust (the German army's bazooka equivalent).
* In the 2013 remake of ''Literature/{{Carrie}}'', the eponymous character sports a rather chilling one during her RoaringRampageOfRevenge. It's especially jarring when compared to the 1976 version of the same scene, in which her face remained frozen in a look of shock.
* ''Film/TheUnknown'': Alonzo's rictus grin when he finds out that Nanon and Malabar got married is something to behold.
* In the second ''Film/{{Wishmaster}}'' film especially the evil Djinn has a perpetual smile on his face to show his joy at the people he can kill and amusement at their [[MuggingTheMonster belief they can boss him around]] (he's in human disguise at the time).
* In ''Film/XMenFirstClass'', Shaw gives one when [[spoiler: he thinks he's convinced Erik to join him.]]
[[/folder]]

[[folder:Literature]]
* Count Olaf in ''Literature/ASeriesOfUnfortunateEvents''.
* A few Death Eaters display this, as does Snape on occasion and Voldemort in the ''Literature/HarryPotter'' series.
* ''Literature/{{Coraline}}'': Done by the Other Mother, when she's not busy being a StepfordSmiler.
* In RobinJarvis' ''[[Literature/DeptfordMice The Dark Portal]],'' a rat called Smiler had a Slasher Smile on his face all the time...because he'd been rude to his superior as a child, and said superior had [[FamilyUnfriendlyViolence cut off his lips]].
* Both Carcer and Mr. Teatime of Creator/TerryPratchett's ''Literature/{{Discworld}}'' books are described as smiling like this ''all the time''. The drawing of Mr. Teatime in ''The Art of Discworld'' perfectly illustrates this. Marc Warren does a good job with this in the TV adaptation, too.
** At one point in ''Discworld/{{Jingo}}'' the seriously pissed off "Vimes's grin was as funny as the one that moves very fast towards drowning men. And has a fin on top."
** Then there's [[OurWerewolvesAreDifferent Angua]], who at one point must have been smiling because "her mouth was open, and [[OhCrap all of her teeth were showing]]".
* A rare heroic version: [[TheBigGuy Ivarian Borenson]], of ''Literature/TheRunelords'' fantasy novels, is known for his chilling laughter and grin as he fights, which makes him feared even amongst warriors who have far more endowments (strength, stamina, speed, and so on taken from other people) than him. Not so much out of a love for killing, but [[GenreSavvy because it works far better at frightening other people than a war cry,]] so he got himself into the habit of laughing instead.
* Lijah Cuu from the ''TabletopGame/{{Warhammer 40000}}: Literature/GauntsGhosts'' novels has one of these. In ''Straight Silver'', it is explicitly noted that "the most evil servants of Chaos would have killed to have a smile that lethal."
** In the next book, Abnett gives Magister Enok Innokenti (one of the most evil servants of Chaos ) an even better one. His smile is so hideous that it causes physical pain and nausea in humans and ''his daemonic bodyguard, who has murdered millions can't bear to look at it.''
* The eponymous creature of Edward Gorey's ''[[http://www.geocities.com/dav485q/wugglies/wuggly1.html The Wuggly Ump]]''.
* Professor Moriarty, SherlockHolmes' arch-enemy from the short story "The Final Problem." Holmes describes that, though Moriarty "smiled and blinked," there was something about the Professor's sunken eyes that made Holmes, a man who was used to danger, very glad to have a revolver with him.
* In Jack Vance's ''Literature/DyingEarth'' series, the character Iucounu the "Laughing Magician" perpetually supports one of these providing a clue that his sense of humor is not exactly benevolent
* Perhaps inspired by the Jack Vance example, Steven Brust's novel ''[[Literature/{{Dragaera}} Five Hundred Years After]]'' has the court wizard as a minor character and he is similarly described as always smiling creepily and chuckling in a questionably sane manner.
* ''Literature/TheNameOfTheWind'': Cinder of the Chandrian, an EvilAlbino, has a smile that is described as "the expression a nightmare wore."
* The huge, catlike Kzinti of Creator/LarryNiven's ''Literature/KnownSpace'' universe instinctively show their teeth when they feel a certain way. That way is ''not'' happy.
* From ''Literature/AliceInWonderland'':
-->"How cheerfully he seems to grin!
--> How neatly spread his claws
--> And welcomes little fishes in
--> with gently smiling jaws!"
* Mr. Grin from the ''Literature/AlexRider'' book ''Stormbreaker''.
* Jaime Lannister of ''Literature/ASongOfIceAndFire'' recalls in his youth facing a particularly brutal and psychotic fighter known as 'The Smiling Knight'. 3 guesses why he is named that. Luckily even a slasher smile is no match for Ser Arthur 'The Sword in the Morning' Dayne and his [[ThunderboltIron greatsword Dawn]].
* The Hellebore family from the TadWilliams book ''Literature/TheWarOfTheFlowers'' liked these. Anton Hellebore was described as having a smile like someone who'd learned it from a book, Lord Hellebore one with absolutely no good feelings in it, and the Terrible Child had one like someone pulling up the corners of a corpse's mouth.
* Creepy caretaker Heimertz from the ''Literature/EdgarAndEllen'' series has a constant slasher smile. During the Tv adaptation it is shown that he has had this smile since he was a child.
* OlderThanPrint: Skarphéðinn Njálsson has one in ''[[Literature/TheIcelandicSagas Brennu-Njáls Saga]]''. "And he grinned." is a common phrase in the story that implies that something really bad is about to go down.
* Randall Flagg/The Dark Man, is described as having a grin of such good cheer and jolliness which comes across however as so unsettling the human mind seems to block it out.
** Also from ''Literature/TheStand'' (where King first writes about Flagg) is Harold. Most of the other survivors in Boulder just see him as a StepfordSmiler... but the slightly damaged child Leo sees things a little differently.
--> It's like there are worms behind his eyes, and they're eating his brain and making him smile like that.
* Jame, the heroine of P.C. Hodgell's ''Literature/ChroniclesOfTheKencyrath'' series, smiles like this, and it is very, very bad news. It signifies the depths of her darkness, and the author said, "In a way, everything about Jame grew out of that chilling smile."
* In the ''Literature/KateDaniels'' series, Kate is trying to enlist a man's cooperation with her plan to hunt down and kill the people who have hurt her friend.
-->I gave him a smile. I was aiming for sweet, but he turned a shade paler and scooted a bit farther away from me. Note to self: work more on sweet and less on psycho-killer.
* Rictus in Creator/CliveBarker's ''The Thief of Always'' at first seems to be a harmless goofball who's always got a big, cheesy grin on his face - until the dark side of the Holiday House (his employer) makes itself known, and his smile becomes terrifying ([[GeniusBonus if Harvey Swick had read his dictionary]], he'd know that a "rictus" is the grin of a skull).
* In some of the ''Comicbook/XWingSeries'' and any [[NewJediOrder other]] appearances written by Creator/AaronAllston, Wedge Antilles has often been known to smile like this - actually, while it can be assumed that he's got normal smiles, almost any time the narration ''says'' he's smiling it's this trope. Humorless, feral. He gives it to politicians when he sees through what they say to what they mean and most often to enemies he's about to shoot down.
** In the same books, "Runt" Ekwesh (being non-human) has a facial structure that even a friendly smile is described as looking like a prelude to a biting attack. He's keenly aware of this and takes full advantage of it when he wants to be menacing.
** ''Literature/LegacyOfTheForce'' has Wedge shocked and taken aback by being discharged - Wedge, who was sixty and had been in service since the age of twenty - then realizing that people are going to try to kill him. The thought is so familiar that it steadies and reassures him, and he's able to flash someone a smile "suggesting that he was a rancor and they were made of meat".
* Sometimes it's a matter of perception. In Creator/AlanDeanFoster's ''The Damned'' trilogy, the first encounter between the multiracial alien alliance's and humans highlights the differences between them and us when the human, Will Dulac, first bats the gun out of the hand of the nearest alien scout out of a self-defense reflex, then offering a handshake and smiling when he realized they weren't hostile. The sudden reflexive strike nearly broke the scout's hand, and the smile confuses and alarms them as they wonder why baring one's teeth could ever be considered a friendly gesture. They also didn't get the handshake.
* Similarly played in David Brin's ''Literature/{{Uplift}} War'' when an allied alien found it disturbing that humans bared their teeth and bark when amused.
* In Creator/RobertEHoward's ''Franchise/ConanTheBarbarian'' story "Literature/AWitchShallBeBorn", Constantius does this while watching the guard be slaughtered and crucifying Conan.
* Geralt of Rivia is frequently said to be "smiling nastily," usually either to intimidate or show his supreme disdain for an idea or position that he's been put in.
* Gwynplaine from ''Literature/TheManWhoLaughs'', as touched upon under the examples of The Joker and Mr. Sardonicus.
* The Steel Inquisitors from ''Literature/{{Mistborn}}'' are exceptionally brutal enforcers of the Empire, and the chilling grins they have when going about their work are frequently remarked on. AntiHero Kelsier, leader of the rebellion, also smiles a lot because it's a way of proving that he's not beaten down, but from the point of view of his enemies (to whom he has little to no mercy) it comes off like this.
* Vlad Dracula in ''Literature/CountAndCountess''. Every time he's about to kill someone with his artificially sharpened teeth, he grins at them first, just to give them a preview of what's to come.
* In DevonMonk's Literature/AllieBeckstrom novel ''Magic in the Blood'' the villain does this while making demands on Allie.
* Nathan in ''Literature/KillTimeOrDieTrying'' does this inadvertently; it's just how he naturally smiles.
* Portia Hoechst, in Creator/CharlesStross's ''[[Literature/TheEschatonSeries Iron Sunrise]]'', is described as having this by several other characters, both good and evil, in the novel.
* Skeeter Traps from ''Literature/ChroniclesOfMagic'' is known for sporting these, despite being a ten year-old girl. Combined with the fact that she can kill grown men three times her size, it makes her pretty scary.

[[folder: Live Action TV ]]
* Male {{Yandere}} Masato Kusaka from ''Series/KamenRiderFaiz'' does [[http://static.tvtropes.org/pmwiki/pub/images/kusaka01_9124.jpg this]] when he's [[http://static.tvtropes.org/pmwiki/pub/images/kusakacreepysmile_4521.jpg about to]] MurderTheHypotenuse.
* ''Series/{{Oz}}'': Displayed among the characters like Shillinger, Adebisi, the Aryans, Timmy Kirk, Claire Howell, etc. ManipulativeBastard Chris Keller and Ryan have done this too. Even Beecher, when he was crazy in Season 2.
* An episode of ''Series/XenaWarriorPrincess'' flashes back to the point in her past where Xena went from ruthless but otherwise sane and rational warlord to utterly psychotic rampager; she has one of these grins on her face when she snaps a Roman soldier's neck, but it's her ''eyes'' that are the most disturbing.
* ''Series/BuffyTheVampireSlayer''
** The Gentlemen of the episode "Hush" wear these for the entirety of their appearance. And they never talk, despite gesturing at each other ''as if'' they were talking. The entire effect is ridiculously creepy.
** The Gnarl, a skin-eating creature shown in "Same Time, Same Place", pulls this off chillingly. The smile is combined with a childlike personality, and it speaks in singsong, like it's telling nursery rhymes.
** Der Kindestod in season 2 who eats up kids' life force by pinning them down, extending horrible little pipes from his eyes and sucking the energy out of their foreheads, while they screamed helplessly under him.
** The First does this as it's impersonating Cassie.
** Angelus, Spike, Warren, and Buffy herself. She flashes a pretty smile [[BullyHunter to a group of bullies]]. Given some think she is crazy, others remember she burnt down her previous school's gym, and is on record for being a multiple murder suspect, is enough to make them back off.
* In "Mirror, Mirror" from ''StarTrekTheOriginalSeries'', Mirror Chekhov pulls one of these right before the commercial break when he momentarily has Kirk at his mercy:
-->'''Mirror Chekhov''': "So, keptin, you die... [[KlingonPromotion and ve all move up in rank]]. No vun vill qvestion the assessination of a keptin who has disobeyed prime Starfleet orders!"
* A particularly lame episode of ''Series/StarTrekTheNextGeneration'' has Data practicing his dance moves on the Holodeck while wearing an extremely disturbing, frozen rictus-like smile.
** Gowron, on the other hand, mastered this trope and showed it off in almost every appearance.
* In the Enzyte Commercials, Smilin' Bob has one of the most unnatural smiles ever seen in an advertisement. It's not MEANT to be a Slasher Smile, but still... BRRR!
* Scorpius of ''Series/{{Farscape}}'' fame is infamous for these during his [[SugarWiki/CrowningMomentOfAwesome Crowning Moments of Awesome]] - accompanied by his black gums and needle-sharp teeth.
* Not uncommon on ''Series/TheLeagueOfGentlemen'', it being the horror filling station that it is. Most notably used by [[MonsterClown Papa Lazarou]] (who combines a nasty, clownish grin with yellow teeth) and [[TheButcher Hilary Briss]] (whose smile [[TechnicallyASmile really does not reach his eyes]]).
* In the British TV series ''Series/{{Jekyll}}'' the main character's Hyde persona is equipped with a frightening one. It's currently the page illustration.
* ''Series/TheBigBangTheory'''s Sheldon has a particularly [[TheUnSmile disturbing smile]] that prompts his friends to say they're there to congratulate their friend, not kill Franchise/{{Batman}}.
** Disturbing, yes (Howard: "Oh...crap, that's terrifying"), but also a CrowningMomentOfFunny.
* ''Series/{{Reba}}'': Van's "winning smile" is incredibly creepy, and he's completely oblivious to it.
** Van calls it a "killer smile." Reba's description is a lot more accurate.
--> '''Reba''': Van, that's not a killer smile, that's the smile of a killer.
* ''Series/TwinPeaks'': BOB, and [[spoiler: by proxy]] Leland Palmer.
* The killer at the end of the ''Series/CriminalMinds'' episode "Lucky".
* Miranda Hobbes on ''Series/SexAndTheCity'' does one of these when she "fakes a sonogram" (i.e., fakes wild excitement during a sonogram of a child about which she's not quite happy, yet).
* Played for laughs in ''Series/TheFreshPrinceOfBelAir''. Will and Cartlon know that when Uncle Phil smiles and laughs uncontrollably, he's about to explode.
* [[CuteMonsterGirl Jessica]] from ''Series/TrueBlood'' usually makes one of these whenever she is hungry and sees a guy she wants for dinner. However instead of being scary, it makes her look [[MoeStare incredibly cute]].
* Dr. Cox in ''Series/{{Scrubs}}'' is very good at making these, a number of them occurring in J.D.'s {{Imagine Spot}}s.
* Evil!Tommy got in one or two good ones during the "Green With Evil" saga of ''Series/MightyMorphinPowerRangers''.
** [[Series/PowerRangersSPD Sky]] (or rather, the evil alien that swapped bodies with him) did a few of these during the episode "Recognition."
* ''The Stand'': [[http://parkinglotconfessional.files.wordpress.com/2011/04/creepy-randall-flagg.jpg Randall]] [[http://2.bp.blogspot.com/_t8MirDiMGHI/SMCIE4KEy8I/AAAAAAAAATk/_Gzjy1AC0sY/s400/RandallFlagg.jpg Flagg]]
* ''Series/OnceUponATime's'' [[http://1.bp.blogspot.com/-tUQZcldBkf8/UITeoWQpSdI/AAAAAAAAFIg/Kr92IfK5pRs/s1600/Colin+O%2527Donoghue+as+Captain+Hook+on+Once+Upon+A+Time+S02E04+Crocodile+10.png Captain Hook]] pulls off one of these after swearing revenge on his "crocodile." It is ''[[EvilIsSexy hot.]]''
* Toby of the ''Series/DoctorWho'' episode "The Impossible Planet" sports a nasty one while possessed by The Beast.
** [[Series/DoctorWho The Master]] often wears this expression. In his last story, Ainley!Master had fangs to boot. Simm!Master perfected a dishonest politician's smile in his first episodes. After that, he got [[http://dwimages.iimmgg.com/image/f2f95f78d9b97221a2577e46cea6ba35 even creepier.]]
** [[spoiler: As did Davros in his moment of triumph in the 4th series. Well, NEAR-triumph.]]
** Also done by the ninth Doctor when he meets the "alleged" last Dalek in the universe. Thing is, it's armour is completely shut down except for its voice and eyepiece, so what does the Doctor do but give a slasher smile and attempt to "exterminate" the Dalek.
** The Fourth Doctor generally sticks to the CheshireCatGrin, but he does this, usually when he's pretending to be evil or bluffing about how dangerous he is - like his IAmHeAsYouAreHe gambit in "Meglos". Or occasionally when he actually is being violent, like when he snaps a man's neck in "The Seeds of Doom".
* ''Series/GameOfThrones'', Season 3, Episode 4: Viewers, meet [[spoiler: Ramsay Bolton]]
* Sherlock Holmes delivers [[http://www.pinterest.com/pin/535646949402426072/ a rather disturbing one]] in "The Sign of Three."
* [[spoiler: Garrett]] has one on full display just before [[spoiler: he gets vaporized by Coulson]] on ''Series/AgentsOfSHIELD''.
* The Israeli skit show ''The Chamber Quintet'', after the RealLife GutPunch of [[http://en.wikipedia.org/wiki/Assassination_of_Yitzhak_Rabin Prime Minister Yitzkhak Rabin’s assassination]] and [[http://en.wikipedia.org/wiki/Benjamin_Netanyahu Benjamin Netanyahu]] being voted prime minister for the first time, aired [[https://www.youtube.com/watch?v=o6mmTZKtMns this skit]], featuring a monologue by assassin [[http://en.wikipedia.org/wiki/Yigal_Amir Yig'al ‘Amir]] about how the political climate in Israel will take a sharp turn to the extreme, nationalistic right over the course of 20 years, intermittently giving a particularly chilling one. Made worse by the fact that the prophecies in the skit ''[[HarsherInHindsight have already partially come true]]''.

[[folder:Music]]
* Music/MichaelJackson turns to the camera with cat eyes and a creepy smile at the end of his Thriller music video.
** Parodied in the music video for the Music/WeirdAlYankovic song "Eat It".
* One of the detective's [[spoiler: other selves]] in the music video for Music/BlindGuardian's "Another Stranger Me." The band's singer also has a Slasher Smile at one point.
** The {{Monster Clown}}s in Music/BlindGuardian's "Mr. Sandman".
* "The Guy," the {{mascot}} of the metal band Music/{{Disturbed}}, is always depicted with this (''[[FrozenFace always]]''.)
* Music/DannyElfman practically made a living doing this in the 70's and 80's. There's hardly any Music/OingoBoingo music video (or film, for that matter) in which he doesn't spend a few seconds scaring the living crap out of the audience. Overly obnoxious talk show hosts occasionally got the silent treatment from him, combined with a trademark psychotic grin.
* And then there's... well, everyone but the band in the video for Music/{{Soundgarden}}'s "Black Hole Sun".
* In Music/TheBirthdayMassacre's song Happy Birthday ( 3 guesses as to what it's about), there's the lines:
** I think my friend said, "Don't forget the video." / I think my friend said, "Don't forget to smile."
* Music/{{Motorhead}} has a song about this trope called "Smiling Like a Killer."
-->"Go to bed, lock the door,
-->don't look in the mirror,
-->what if I was right behind you,
-->SMILING LIKE A KILLER?"
* The more disturbing of the Music/{{Vocaloid}} music videos feature this, such as the chainsaw-happy "nurse" and the demented victims in the "Dark Woods Circus" series (you can even see a disembodied Slasher Smile behind the flap of the circus tent), and Miku in "Circle you" [[spoiler: ''right before [[TheFourthWallWillNotProtectYou she cleaves you in half with a machete]] , [[JumpScare at the moment when you least expect it.]] it will most likely catch you off guard.'']]
* The cover of Music/AphexTwin's ''Richard D. James Album''.
** Music/AphexTwin fits this trope to a T. He really loves to paste his creepy grin on everything from album covers to music videos. One of most notable appearances of his face is [[http://img366.imageshack.us/img366/6540/aphexly2.png spectrograph at the end of "Equation"]] - an EasterEgg which is cool and disturbing at the same time.
* Technical thrash metal band Coroner have a song entitled "Grin (Nails Hurt)" off the aptly titled "Grin" album, which itself features a pretty sadistic grin.
--> Nails in my brain, all that's left just
--> Grin
--> Grin 'til I lose
--> Until I lose myself
* The [[http://www.youtube.com/watch?v=S4R8HTIgHUU video]] for Music/DavidBowie's "Valentine's Day" consists of just about nothing but David playing guitar while making a Slasher Smile at the camera.

[[folder:Pinball]]
* The Devil in ''Pinball/DevilsDare'' has this on the backglass.
[[/folder]]

[[folder:Professional Wrestling]]
* Wrestling/RandyOrton doesn't smile often, but when he does....
* Wrestling/{{Batista}} could be like this as well, both as a face and as a heel.
* Wrestling/{{Kane}} too. Bonus points for not ''needing'' to smile to look scary.
* Wrestling/BethPhoenix is the rare Diva who is able to smile evilly without making it look the ''least'' bit sexy. ([[FetishFuel Okay, maybe a little....]])
* Wrestling/ChrisBenoit. Especially unnerving, considering what happened to him.
[[/folder]]

[[folder:TabletopGames]]
* ''TabletopGame/{{Exalted}}'s'' signature Dusk Caste Abyssal is known as the Maiden of the Mirthless Smile.
* The [[TheFairFolk Dark Eldar]] of ''TabletopGame/{{Warhammer 40000}}'' are usually depicted with this in artwork. Hardly surprising considering [[CombatSadomasochist what many of they are]].
[[/folder]]

[[folder:Theatre]]
* Umbridge in ''[[Theatre/AVeryPotterMusical A Very Potter Sequel]]''. Especially when she's accusing Cho of being perfect and after she fires Lupin and Harry tells her to "do your worst".
* Red Caboose from ''StarlightExpress''. [[http://bellesdomain.co.uk/stex/brochures/us03_40.jpg And]] [[http://bellesdomain.co.uk/stex/brochures/j90_28.jpg how]] [[http://bellesdomain.co.uk/stex/brochures/b97_22.jpg very]].
* ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'': It is said of Sweeney that he seldom laughed but often smiled.
[[/folder]]

[[folder:Toys]]
* The Piraka of ''Franchise/{{Bionicle}}'' all have giant Slasher Smiles plastered on their faces.
** The story points out that their frowns are ''worse''.
* When photos of the toy for [[KidAppealCharacter Hot]] [[TheLancer Shot]] of ''Anime/TransformersArmada'' showed up, his prototype was shown with [[http://tfwiki.net/wiki/File:ArcherSays.jpg a ridiculously unhinged-looking grin]], apparently a [[OffModel misapplication of the design artist's concept art]]. Fan reaction was immediate and for a while, it was known as the "jAam Smile" after a popular bit of MemeticMutation.

* Hihidaruma/Darmanitan from ''VideoGame/PokemonBlackAndWhite''. Just think about what is going through its mind.
** [[ActionBomb Electrode]] along with Gengar and its relatives, Haunter and Gastly, too. [[EverythingsBetterWithMonkeys Aipom]] has one that manages to be kind of cute.
** Rayquaza doesn't need all its teeth to [[http://images4.wikia.nocookie.net/__cb20100225101049/pokemon/images/e/e8/Rayquaza.jpg look]] [[http://images2.wikia.nocookie.net/__cb20120207223837/halo/images/e/e9/Rayquaza_Normal_Version_by_Xous54.png frightening.]]
** Then there's [[http://cdn.bulbagarden.net/upload/5/5c/Genesect_Army_M16.png Genesect]]. Unlike the previously listed Pokémon, this smile [[FrozenFace seems to be permanent]] due to [[BigBad Team Plasma's]] [[WeCanRebuildHim power-boosting enhancements]].
** As for humans, [[VideoGame/PokemonColosseum Wes]] gives a heroic example when he blows up team Snagem's hideout in the opening.
* Slightly subverted in ''VideoGame/AmericanMcGeesAlice'': The Cheshire Cat had this expression (it's significantly scarier than the CheshireCatGrin his other incarnations wore), but he was one of the few allies the player has in the game, and he never attacks Alice. Still, when he appeared and disappeared grin-first, followed by his crazy eyes, it was prime horror. It was never quite clear whether he was as mad as a box of frogs, or frighteningly sane. Considering the game takes the idea about Wonderland as a construct of Alice's mind to it's conclusion by making Alice [[AxCrazy batshit insane herself]] either possibility ends in horror.
** Alice herself demonstrates one near the end of the game's trailer.
* Kurow Kirishima of ''VideoGame/RivalSchools'' has perfected this trope.
* A picture of B.J. doing this represents the difficulty rating "I am Death Incarnate" on ''[[VideoGame/{{Wolfenstein3D}} Wolfenstein 3D]]'', which was [[http://i.imgur.com/LAQ9FaR.png carried on to the Uber difficulty]] in ''[[VideoGame/{{WolfensteinTheNewOrder}} Wolfenstein: The New Order]]''.
* The ''VideoGame/{{Doom}}'' guy makes this expression when he picks up a new weapon.
* In the opening of ''VideoGame/SuikodenII'', Luca Blight has one of the most frighteningly evil {{Slasher Smile}}s imaginable, bordering on horror (a look that he keeps consistent throughout the game) and isn't just holding an axe or a knife, he's holding a decapitated head.
* Normally, Akuma in ''Franchise/StreetFighter'' is a PerpetualFrowner. On the occasions he becomes Shin Akuma, however, his face twists into a horrific grin.
** Adon also has a permanent one, although he's actually a subversion because aside from the evil grin, he's not insane or AxCrazy.
** The not so well known variant of Ken, known as [[VideoGame/SNKVsCapcom Violent Ken]], has one permanently plastered on his face. His altered nonchalant sounding voice and relaxed fighting stance makes him even creepier. His best attack involves screaming like a psychopath and panting heavily at the end just to seal the deal.
* Magaki in ''VideoGame/TheKingOfFighters XI'' has a terrible smile frozen on his face the entire time you fight him.
* Two bosses in ''VideoGame/WarioLand 4'', Cractus and Spoiled Rotten, twist their faces into grotesque, rabid grins after they've been hit several times. The freakiness is magnified by the fact that their heads alone take up more of the screen than Wario does.
* Two characters in ''VideoGame/{{Drakengard}}'' display this: Caim, the dark and vicious AntiHero, and Arioch, the AxCrazy ActionGirl.
** Caim's is more noticeable in [[http://www.youtube.com/watch?v=aWIAbF-Gr0o the sequel.]]
* Kefka, from ''VideoGame/FinalFantasyVI'', has a sprite with NoMouth much of the time, but you ''just know'' he's sporting one of these.
** If one looks closely at his [[OneWingedAngel final form]], you'll notice that he does in fact sport this smile. Either that, or a PsychoticSmirk.
** Dissidia tells us that he definitely is. Complete with [[Film/TheDarkKnight Heath Ledger-style Joker makeup]].
* The Horseless Headless Horsemann from ''VideoGame/TeamFortress2'' has one of these carved into his jack o' lantern head, as well as on his [[WeaponOfChoice huge ax]].
* Jackle in ''VideoGame/NightsIntoDreams'' is constantly wearing one plastered over his otherwise invisible face. You kind of get the picture that he's absolutely insane, because just adding that evil cackle... *shudder*
* Sweet Tooth of ''VideoGame/TwistedMetal'', and in fact most {{monster clown}}s.
** Calypso from the same series might apply if you count most of the endings for ''VideoGame/TwistedMetal 2''.
* The [[MeaningfulName Heaven Smile]] creatures from ''VideoGame/{{Killer 7}}'' have these all the time. This, combined with their [[EvilLaugh freaky laughter]], makes them horrifying for many players.
** All that concept art where Dan Smith does it.
* Baraka from ''Franchise/MortalKombat'' perpetually has a deranged, fanged one that distorts his entire face. This, along with his {{glowing|EyesOfDoom}} cat-eyes, can be a bit distracting to some players.
** Mileena has a similar smile on her face, one that's usually hidden behind her ninja mask.
** This is due mostly to the fact that both are Tarkatan (well, Mileena is half Tarkatan) and [[MoreTeethThanTheOsmondFamily thus have pointy teeth too big to be covered by their lips.]]
* The Happy Mask Salesman of ''VideoGame/TheLegendOfZeldaMajorasMask'' almost always combines this with EyesAlwaysShut. When he ''stops'' smiling and his eyes open, he shows his other expression: unimaginable rage. The Link [[NightmareFuel Elegy of Emptiness statue]] also has it.
** Memorably done in ''VideoGame/TheLegendOfZeldaTwilightPrincess'', by Midna in a flashback sequence. In fairness, she was a bit nasty and more of an AntiHero at the time, but grew out of it with some CharacterDevelopment.
** Cole from ''VideoGame/TheLegendOfZeldaSpiritTracks''.
--> "So why don't you go polish up that train of yours? Not that it matters much..." *insert smile* "The thing will be useless before long..."
** After killing Hectan in ''[[VideoGame/TheLegendOfZeldaCDiGames The Wand of Gamelon]]'', Zelda says "Good" and smiles.
* Emil of ''VideoGame/TalesOfSymphonia'' gets one of these during his [[http://www.youtube.com/watch?v=X6TBySMxhhI Devil's Hellfire]] [[LimitBreak Mystic Arte]]. Made all the more disturbing since Emil (outside of [[SuperpoweredEvilSide Ratatosk mode]]) is normally a milquetoast to rival [[ComicStrip/{{Peanuts}} Charlie Brown]] himself.
** Alice from the same game appears to have this as well. The way she occasionally switches from her typical smiley expressions to her evil-/scary-looking one in a single instant is so creepy it makes her bear an uncanny resemblance to a [[VideoGame/TheLegendOfZeldaMajorasMask certain aforementioned mask salesman...]]
* Alexei from ''VideoGame/TalesOfVesperia'' displays one in [[SuperMovePortraitAttack his cut-in]] just before the climax of his Brilliant Cataclysm mystic arte.
* Barbatos Goetia displays a very unsettling one for his "No Items Ever!" mystic arte in the {{P|layStation2}}S2 remake of ''VideoGame/TalesOfDestiny''.
* The little ghosts that appear mostly in [[{{Halloweentown}} Pumpkin Hill]], and dotted around other stages in ''VideoGame/SonicAdventure2'' each have a rather creepy, fanged, smile.
* Karel of ''Franchise/FireEmblem'' is an AntiHero with this. He's also something of an AxCrazy guy, considering he both constantly talks about loving to kill and he also [[spoiler:murdered his whole family so he could get a sword]]. By the way, he looks like this [[http://www.rpgfan.com/pics/fire-emblem-rnk/art-024.jpg]].
** [[spoiler: Zephiel has one at the end of ''Franchise/FireEmblem: [[VideoGame/FireEmblemElibe Rekka no Ken]]'' as well.]]
** Ashnard, Mad King of Daein and main antagonist of ''[[VideoGame/FireEmblemTellius Path of Radiance]]'', is probably the definitive example.
* The Chrysalids ([[http://www.ufopaedia.org/index.php?title=Chrysalid UFO Wiki link]]) from ''VideoGame/{{X-COM}}''.
** Similarly, their masters, the Snakemen, have a wicked toothy smile. But then again, they don't have any visible lips.
* The Replica assassins ([[http://fear.wikia.com/wiki/File:POAssassin.jpg image link]]) from ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R.]]''
** [[ImAHumanitarian Paxton Fettel]] has one of these plastered on his face almost constantly.
* The ''VideoGame/YumeNikki'' fangame ''DotFlow'' has some of these, as shown in this walk-around video ([[http://www.youtube.com/watch?v=PPNpFkzBn5w video link]]) -- for example, there are quite a few shark-toothed, bloody-grinning white blob things (whose faces are otherwise featureless) in the area first entered at 1:20, and the painting at 15:14 is of a surreal abstract line-art slasher smile.
** There are also at least two places in ''[[DotFlow .flow]]'' where [[spoiler:the walls are '''made of''' those slasher-smiling white things, their mouths open even wider, and in one place it looks like their skins are strung up with the smiles still in the middle... even worse, the entrances to these places '''are''' the mouths of the white creatures]]. There's a video of these areas, too ([[http://www.youtube.com/watch?v=RTIkxnPcUIA&feature=related video link]]) -- one of the areas is entered first at 1:11, and more of it and the second area are shown starting at 7:40.
** When the re-occurring character known as [[ExactlyWhatItSaysOnTheTin 'Smile']] is struck with the steel pipe, he gets one of these. After the event occurs, Smile will grin every time you pull out the pipe in front of him... (for the morbidly curious, here's the recorded event: [[http://www.youtube.com/watch?v=2jpftgZrEmQ&feature=related video link]]
* AxCrazy [[spoiler:pre-HeelFaceTurn Maverick Zero]], as seen before the climax of ''VideoGame/MegaManX4''. And fitting, since ''he's built for the sole purpose of destroying the world''.
** [[VideoGame/MegaManClassic Bass]] in the original series mostly looks like TheStoic. When he does smile, however, it's invariably either a PsychoticSmirk or this trope. [[http://megaman.wikia.com/wiki/File:Forte_manga.jpg Behold!]]
* Vanitas, once you finally see him without the helmet in ''VideoGame/KingdomHeartsBirthBySleep,'' [[http://i178.photobucket.com/albums/w245/megaflamehedge/spoilers/18.png is rather good]] [[http://i178.photobucket.com/albums/w245/megaflamehedge/spoilers/19.png at these.]] (WARNING: both images are major spoilers.)
** Several kinds of [[TheHeartless heartless]] have permanent smiles plastered on their faces.
* In ''VideoGame/{{Persona 3}}'', the [[spoiler:Thirteenth]] Shadow of the [[spoiler:Death]] Arcana ([[spoiler: [[TheGrimReaper Nyx Avatar]]]]) sports a mask which is nothing but a pair of hollows for eyes and an immense grinning mouth; this is in contrast to other Major Arcana Shadows, whose masks are either inhuman or emotionless. Ironically, it spends most of the fight speaking in a [[TragicMonster defeated-sounding]] monotone.
** [[CanonName Makoto]] himself gets a pretty nasty smile the first time he summons his persona, which isn't helped by the [[DoesThisRemindYouOfAnything gruesome summoning method]].
** The real killer in ''VideoGame/{{Persona 4}}'', [[spoiler:Adachi]], sports one of these when chased into the TV world. He gets a new one in [[UpdatedRerelease The Golden]] [[spoiler:if you complete his social link and become his accomplice.]]
* For the main ''VideoGame/ShinMegamiTensei'' games, the cover for ''VideoGame/ShinMegamiTenseiIV'' has [[AntiHero Walter]] sporting one of these.
** [[spoiler: Issachar]] also suddenly sports one of these when he begins to turn into a demon.
* Certain levels in ''VideoGame/{{WET}}'' has a random {{mook|s}} charging Rubi, who promptly shoots them. Blood sprays onto her face, which triggers Rage Mode and she wears a psychotically evil slasher smile throughout the level.
** She also flashes one when she uses her sword to [[GroinAttack slice someone's wee wee off]].
* Scarlet from ''VideoGame/SilentHillHomecoming''.
* The fairy queen in the fake ending cutscene of ''VideoGame/Kirby64TheCrystalShards'', revealing that [[TrueFinalBoss Zero-Two is still possessing her]].
* A heroic (and utterly strange) example is [[VideoGame/JakAndDaxter Daxter]]. The reason it's strange is that he's a [[CrouchingMoronHiddenBadass goofy wisecracking sidekick with a bit of badass thrown in]]. Only shown off in-game by his SuperpoweredEvilSide. Every other time, it's part of an HD image promoting ''Jak X''.
* [[OurGoblinsAreDifferent Goblins]] wear these in the VideoGame/{{Warcraft}} [[VideoGame/WorldOfWarcraft series]]. The Goblin Shredder pilot has a particularly mad grin.
** Another, arguably better-known example can be found in Arthas Menethil after he becomes the Lich King. In [[http://us.media.blizzard.com/wow/media/artwork/wow-wrath/artwork-lk02-large.jpg almost]] [[http://media.giantbomb.com/uploads/1/13827/354759-warcraft_3__i_.jpg every]] [[http://us.media.blizzard.com/wow/media/artwork/wow-wrath/artwork-arthas-large.jpg piece]] of official artwork where his face is clearly visible, he is generally shown wearing a grin that is in no way healthy. In fact, this seems to be his stock expression whenever he isn't wearing his helmet.
* [[spoiler: Matt Engarde]] shows a particularly disturbing one when you make him show his true colors in the second ''VisualNovel/AceAttorney'' game.
** In ''Investigations'' [[spoiler:Shih-na]] gets a bit of one when unmasked as one of the villains before eventually going on to a full-blown ''{{VisualNovel/Higurashi|NoNakuKoroNi}}''-style EvilLaugh.
*** As does [[spoiler: Manfred von Karma]], although it's only slightly creepy unless you know that [[spoiler: he murdered Edgeworth's father. AAI doesn't specifically spell it out, most likely to avoid spoiling those who haven't played the original game, but to those in the know it's creepy. ]]
* In ''Franchise/DragonAge'', both hurlocks and genlocks sport permanent Slasher Smiles and it's arguable that Shrieks also have one.
* Hot Coldman, in ''VideoGame/MetalGearSolidPeaceWalker'', constantly smiles rather psychotically during his appearances. In fact, outside of being the man [[MoralEventHorizon who set The Boss up]] or [[BaldOfEvil The baldie]], probably the most recognizable characteristic of his ''is'' the smile.
** [[DepravedBisexual Vamp]] does this a lot too.
** The [[spoiler:fake]] Colonel from ''VideoGame/MetalGearSolid2SonsOfLiberty'', during his conversation with Raiden [[spoiler:nearing the end of the game]], occasionally gives off a [[GlasgowGrin Glasgow-esque grin]] (akin to Heath Ledger's Joker character or Dissidia's redesign of Kefka Palazzo.). Justified, as during these occasions, the Colonel's face often takes a form resembling a skull.
** Jetstream Sam's introduction scene in ''VideoGame/MetalGearRisingRevengeance'' comes with one of these. It just looks ''wrong'' on several levels, UncannyValley inclusive, but this is probably intentional to add an additional sense of unease to him.
** Raiden also sports several in the same game, after [[spoiler: reawakening his [[AxCrazy Jack the Ripper]] persona]].
** In ''VideoGame/{{Metal Gear Solid 3|SnakeEater}}'', Colonel Volgin flashes quite a lot of these, usually before cheerfully committing acts of depraved cruelty and evil. His most memorable slasher smiles occur when he [[spoiler: nukes his own country]] just [[ForTheEvulz for the hell of it]], when he sees that [[spoiler:Snake has lost bladder control because of how intensely he's being tortured]], while saying "[[{{Squick}} Yes! Yes! ''That's'' what I want to see!]]" His other most memorable one is when he controls the Shagohod, and, while laughing maniacally, mows down his own men, again, seemingly just because he can. A lot of these traits are why Volgin is one of the few villans in the Metal Gear franchise to have next to no fans who sympathize with him, because he has no FreudianExcuse, no underlying issues, other than an extreme and insatiable sadism.
* In ''VideoGame/BlazBlue'', Jin gets to sport one of these whenever he's around Ragna.
** In the sequel we have [[spoiler: Hazama/Terumi]] who's smile is perfectly fitting for his [[AxCrazy batshit insane]] personality. Especially on the Japanese audio track.
* Dimentio in ''VideoGame/SuperPaperMario'' is heavily implied to have a constant smile especially when committing very atrocious acts such as murder.
** Always sported by Fawful from [[VideoGame/MarioAndLuigi Mario & Luigi]].
* Rajan shows one in ''VideoGame/Sly2BandOfThieves'' before the title card for "The Predator Awaits" episode, (and for the picture for the chapter) Dimitri shows one to a lesser extent at the end of his intro scene, along with crazy ass eyes.
* Schwartz, the protagonist of the second generation in ''VideoGame/AgarestSenki 2'' sports this when he is about to kick someone's ass all over the place.
* [[spoiler:Red Savarin]] of ''VideoGame/{{Solatorobo}}'' gets an absolutely crazy one when The Order is given. His usual upbeat, happy-yet-stubborn demeanor means it's ''even creepier''.
* [[spoiler:Barthandelus]], BigBad of ''VideoGame/FinalFantasyXIII'', sports one of these at all times in his true form as a [[PhysicalGod fal'Cie]]. In his [[RecurringBoss first]] battle, he even has an attack called ''"Thanatosian Smile"'', which later gets upgraded to [[EvilLaugh "Thanatosian Laughter"]].
* In ''VideoGame/BillyHatcherAndTheGiantEgg'', any crow enemy will always have a ''massive'' one on its mug.
** Likewise, this extends to all the bosses too, save for Dark Raven and ''maybe'' Dark Corvo.
* ''VideoGame/HauntingGround'': Daniella (The Maid) spends a lot of her screen-time doing this, or laughing rather... [[ImmodestOrgasm interestingly]]. [[http://ezprint.dwdata.com/img/4a7d688b732c565514bf60fda431b65d_11504208660.jpg See]] [[http://ezprint.dwdata.com/img/00c43b07ea898854556832b54aed8b68_11504204810.jpg for]] [[http://images3.wikia.nocookie.net/__cb20110416231506/clocktower/images/3/34/DaniellaClose.jpg yourself]].
* Brad Kilstein in ''VideoGame/PsychicForce'' tends to sport this, especially when his [[SplitPersonality 'sadistic killer side']] emerges. Which is... most of the time.
* When Haseo [[spoiler: awakens his Skeith Avatar]] in ''[[VideoGame/DotHackGU .Hack//G.U.]]'' volume one he's revealed to be wearing one after [[spoiler: he summons Skeith's scythe and prepares to use it to slaughter Bordeaux and her lackeys.]]
* Master Contra from ''Neo VideoGame/{{Contra}}''.
* Found on one of the last fictional characters you'd expect in ''VideoGame/EpicMickey''. Should you decide to take the troublemaker path with Mickey himself, he'll begin to crouch low and sport one of these grins, looking all the more like a rat than a mouse in the process.
* Doctor Minoru Kamiya in Yu Yu Tokubetuhen flashes one of these when using his scalpel attack.
* [[VideoGame/KirbySuperStar Dedede]] of all characters manages a surprisingly creepy one in [[http://www.youtube.com/watch?v=-D8kXIEuOwU the intro for gourmet race]]
* The BigBad of ''VideoGame/GhostTrick'', [[spoiler:Yomiel]], wears one of these when he is first encountered. It's made especially unnerving by the fact that [[spoiler:he looks identical to the main character Sissel]].
* Oblio of ''Dance Central'' when dancing "Body Movin" gives a smile that's just scary.
* The Super Mutants in ''VideoGame/{{Fallout 3}}'' and ''VideoGame/FalloutNewVegas'' have a permanent grinning expression.
[[/folder]]

[[folder:Visual Novels]]
* The dragon in ''VisualNovel/DraKoi'' has a slasher smile for her default smile. The protagonist kind of hates it, even in the good ending.
* [[spoiler: Kotonoha]], in the one of the bad endings of ''VisualNovel/SchoolDays''. [[spoiler: The one where she kills Sekai, more specifically]]
** [[spoiler: Sekai]] also gets one in another of the bad endings when [[spoiler: she kills Kotonoha.]]
* Gilgamesh of ''VisualNovel/FateStayNight'' shows off a particularly disturbing one of these after [[spoiler: making the Holy Grail manifest in the U.B.W. story route]]. For a 'yippee, destruction and fire!' variant, watch the activation of his best Noble Phantasm, or get an eyeful of [[http://img40.imageshack.us/img40/2207/491i.jpg this image]].
* In ''VisualNovel/NineHoursNinePersonsNineDoors'', [[spoiler:Clover]] has one in the [[spoiler:Axe Ending.]]
* ''VisualNovel/CorpseParty'' has several. [[spoiler:There's possessed Ayumi, Kizami, Sachiko, and the shadowy creature at the end of Chapter One (if it catches you)... who turns out to be Sachiko's mother.]]
[[/folder]]

[[folder: Web Comics]]
* The Jägermonsters (clawed, fanged, monstrous {{super soldier}}s) from ''Webcomic/GirlGenius'' have been known to do this - and most of them are on the ''good guys''' side.
** The eponymous heroine herself, though not a violent person, is also prone to sporting a scary grin when she's in [[TheMadnessPlace the "madness place"]], i.e. in the throes of a bout of mad SCIENCE! And when she does, the ''Jägermonsters'' stay out of her way...
*** She also sports this smile fairly often when [[spoiler:possessed by the Big Bad.]]
** The comic's resident [[AxCrazy bloodthirsty maniac]], Bangladesh [=DuPree=], breaks out one quite often. When she does, ''run.''
** [[http://www.girlgeniusonline.com/comic.php?date=20081105 Gil, too]], when he's in a ''really'' bad mood. Or when he knows something bad is going to happen... to you.
** ''All'' the Sparks do it any time they go into TheMadnessPlace. Along with the changing speech bubbles, it's the biggest visual cue.
* Played for laughs in ''Webcomic/QuestionableContent'' when Dora puts her foot down on Faye being friendly to customers, and the best she can manage is scaring them off with what Dora calls a [[http://www.questionablecontent.net/view.php?comic=1215 "horrible rictus."]] The title of the strip is even "[[Film/TheDarkKnight Why So Serious?]]"
** Dora sports one of her own [[http://www.questionablecontent.net/view.php?comic=1323 here.]] The broadsword doesn't hurt, either.
** And Hannelore displays a [[http://www.questionablecontent.net/view.php?comic=1585 very disturbing one]] when she sees a nice little kitty named Mieville.
*** [[http://questionablecontent.net/view.php?comic=1584 The cat in question also used one in the previous strip.]]
**** And from Jeph's Livejournal: [[http://www.questionablecontent.net/random/friends.png FRIENDS]]
* Jenny Curtiss uses this to convince her boss in [[http://techfox.comicgenesis.com/d/20020703.html this]] scene from ''Webcomic/TwentyFirstCenturyFox''.
** The author even hangs a ShoutOut lampshade on it.
*** Which leads us to...
* Florence Ambrose from ''Webcomic/{{Freefall}}'' often [[http://freefall.purrsia.com/ff1500/fc01453.htm falls prey]] to [[http://freefall.purrsia.com/ff400/fv00354.htm this by accident]] when trying to be friendly, probably because she's a genetically engineered anthropomorphic wolf.
** She uses it [[http://freefall.purrsia.com/ff100/fv00098.htm deliberately]] to convince Sam to do what she wants him to.
* ''Webcomic/NoRestForTheWicked'' has [[http://www.forthewicked.net/archive/03-46.html a classic instance]] from the quite-probably AxCrazy [[Literature/LittleRedRidingHood Red]].
* PsychoForHire Belkar from ''Webcomic/TheOrderOfTheStick'' sports one in [[http://www.giantitp.com/comics/oots0620.html this issue]], causing his DangerouslyGenreSavvy party members to run for their lives.
** [[http://www.giantitp.com/comics/oots0611.html This issue]] as well.
* Joel of ''Webcomic/{{Concession}}'' sports a prime example [[http://concessioncomic.com/index.php?pid=20090317 here]].
* This is the default facial expression for [[http://www.wncomic.com/images/characters/lawler.jpg Lawler]], the PsychoForHire of ''Webcomic/WhiteNoise''.
* ''Webcomic/{{Lackadaisy}}'' trouble boys [[LovableRogue Rocky]] Rickaby and [[HiddenDepths Calvin]] [=McMurray=] both possess [[http://lackadaisycats.com/comic.php?comicid=49 alarming]] [[http://www.lackadaisycats.com/comic.php?comicid=78 smiles]]. This is one of Rocky's [[CheshireCatGrin primary expressions]], but for quiet, unassuming, Calvin, it generally doesn't show unless he's [[AxCrazy pumping]] [[LaughingMad someone]] [[PutTheLaughterInSlaughter full of lead]].
** "I thought this was my sincere smile. Isn't this my sincere smile?"
** Mordecai, a [[ProfessionalKiller killer-for-hire]] who has a [[FourEyesZeroSoul hard time with emotions]], managed to unsettle Viktor when his [[http://www.lackadaisycats.com/exhibit.php?exhibitid=29 attempt]] at a seductive smile turned into one of these.
* [[SociopathicHero Ken]] from ''Webcomic/NoNeedForBushido'' has a memorable one going [[http://noneedforbushido.com/2009/comic/358/ in the last panel of this comic]]. It's worth noting that he also has one both in the strip before that one and two strips after. Those poor {{mooks}}...
* Nina in [[http://www.eeriecuties.com/strips-ec/kitty this]] ''Webcomic/EerieCuties'' strip.
* Kimi of ''Webcomic/CaribbeanBlue'' [[http://cblue.katbox.net/index.php?strip_id=183 here]].
* Of all people, Rayne from ''Webcomic/LeastICouldDo'' sports one [[http://leasticoulddo.com/comic/20091026 here. ]]
* ''Webcomic/CryHavoc'' has Skoll, who sports one when fighting hand to hand against a fire team of rebels armed only with a sword.
* Osiris of Webcomic/{{Voices}} is a Heroic example, initially of the SociopathicHero type, later less so.
* Visarah from ''Webcomic/{{Uncreation}}.'' Talk about [[http://uncreation.comicdish.com/index.php?pageID=16 nightmare fuel]].
* VideoGame/{{Mega Man|Classic}} from ''Webcomic/BobAndGeorge'' tends to have one whenever [[http://www.bobandgeorge.com/archives/050107 Ran-bombs]] are brought up.
* Vriska Serket of ''Webcomic/{{Homestuck}}'' wears the biggest shit-eating smile possible as she [[spoiler: waves Tavros's severed legs in front of him, just before impaling him on a lance and throwing him off a cliff.]]
** That's at least a semi-comedic example, since both Vriska's expression and gesture are [[CrossesTheLineTwice just too ludicrously twisted]] to be taken seriously... but if you're interested in an example played ''bone-chillingly'' straight, why not say hello to [[spoiler: [[http://www.mspaintadventures.com/?s=6&p=005342 Gamzee]]]]?
** Aradia, of all [[EmotionlessGirl people]], pulls one right before she [[spoiler: [[http://www.mspaintadventures.com/scratch.php?s=6&p=005197 timestops Bec Noir]]]].
*** She also sports one for a substantial chunk of Act 6 Intermission 5, creeping John out immensely.
*** This latter instance has become MemeticMutation, and it has become a popular activity on Website/{{Tumblr}} and Website/{{Facebook}} to cut and paste Aradia's face into places it does not belong.
** [[spoiler:Caliborn]] arguably tops them all. During his [[TheReveal Reveal]], his psychotic grin is utterly terrifying - and he pulls it right before he ''chews his own leg off''.
** [[spoiler:Jane]], when entering [[spoiler:Trickster Mode]] after [[spoiler:licking the combined juju lollipop]]. There's a whole dance and everything. It's truly terrifying.
* Wrecking Paul from ''Webcomic/EverydayHeroes'', in [[http://www.webcomicsnation.com/eddurd/everydayheroes/series.php?view=single&ID=142744 this strip.]]
* Penny Levac of ''Webcomic/PennyAndAggie'' manages ''two'' distinct ones in [[http://www.pennyandaggie.com/index.php?p=432 this strip]].
* [[Webcomic/WebcomicsUnited Mr. Ohm]] has done ''[[http://comic.guedesav.blog.br/strip/97 things]]'' in high school. Whatever it was, it can't be good. Not with that sharky smile of his...
* Emperor Luca [=deSadar=] from ''Webcomic/TheMeek'' gets some wide, toothy smiles while debating an ambassador from another country about the other country's recent history of genocide and torture against his people. It doesn't help that it's been strongly hinted that Luca suffered those tortures personally, or that the author has specifically stated that big, toothy grins are ''not'' associated with good humor in his culture. [[http://www.meekcomic.com/2009/11/03/2-11/ See for yourself]].
* [[KnifeNut Seth Williams]] of ''Webcomic/{{Remus}}'' sports one [[http://www.remuscomic.com/2012/02/20/018/ here]], right before he [[ColdBloodedTorture has "a little fun"]] with Ryan.
* Mike of the {{Walkyverse}} hardly ever smiles. [[http://www.shortpacked.com/2010/comic/book-11/02-the-relationshipocalypse/smile/ Thank god.]]
* ''Webcomic/OlympusOverdrive'': Eris has one. "We could all use a little ''discord'' after all!"
* ''Webcomic/{{Karin-dou 4koma}}'': Ran's attempt to force a laugh turns into something like this, causing Tamaryu and Shisuki to [[PottyFailure piss themselves in fear]]. Her "smile" makes another appearance while groping Tamaryu.
* ''[[{{Webcomic/morphe}} morphE]]'' features [[http://morphe.thewebcomic.com/comics/1677596/page-4-getem/ a knife wielding woman with a slasher grin]] in the prologue.
* The Sarnothi in ''{{Webcomic/Selkie}}'' can easily pull this off - especially with their being apex predators with MoreTeethThanTheOsmondFamily.
[[/folder]]

[[folder: Web Original]]
* Trollface, of course.
* Tez On Toast from ''WebVideo/KateModern'', for whom this expression may as well be a smile of recognition. Truly chilling.
* The Tails Doll Short, which can be found [[http://comickpro.deviantart.com/art/Tails-Doll-79228090?offset=50#comments here]]. You will never, EVER look at [[Franchise/SonicTheHedgehog Tails]] the same way again.
* Red, the fox from Roleplay/RubyQuest, has a slasher smile which is of [[EldritchAbomination Eldritch Origin]].
* {{WebVideo/Ask That Guy|WithTheGlasses}} will tell you all about this, in great detail. Just ask him.
** WebVideo/TheCinemaSnob. He's a dashingly handsome man, but he has a [[http://i322.photobucket.com/albums/nn407/Icaenea/SlasherSnob.jpg creepy smile]]. Jack Nicholson, anyone?
** [[WebVideo/BadMovieBeatdown Film Brain]] can have some very creepy smiles at times.
** WebVideo/TheNostalgiaChick is a gorgeous lady, but Lindsay smiling genuinely is ''very'' different from the Chick's usual grin, which is just far too wide and teeth baring-y to be anything but disturbing.
** [[WebVideo/WhatTheFuckIsWrongWithYou Nash]] has one that regularly scares the hell out of viewers.
* Played with in the ''WebVideo/YuGiOhTheAbridgedSeries'' with Kaiba's normal-looking, yet still-disturbing smile. "Every time Kaiba smiles, a puppy dies."
** He does it [[spoiler:twice]] in the newly released Episode 42.
---> ''[[spoiler: [As Odion summons Mega-Ultra Chicken]]]''\\
'''Kaiba[Grinning]:''' Oh god yes! ''["+ 100 Dead Puppies" is written on the bottom]''
* Flippy from ''WebAnimation/HappyTreeFriends'' whenever he goes into AxCrazy mode.
* Kirby has a biiiiig one in ''WebVideo/ThereWillBeBrawl''.
* [[http://knowyourmeme.com/memes/dr-nagyfi-rich%C3%A1rd Dr. Nagyfi Richárd]] often sports a version of this.
* Creator/StuartAshen sports one at the beginning of his "[[http://www.youtube.com/watch?v=jX9veeOMxeQ Video Remix Competition]]" video, just before his FourthWallGreeting.
* Jack Douglass of WebVideo/JacksFilms is known for his, generally referred to by fans as the "Creeper Face".
* Pinkie Pie from the [[http://www.youtube.com/watch?v=PqVVtaWd8Pw video]] ''WebAnimation/{{Smile}}''.
* Simon in ''WebVideo/TheCartoonMan'', particularly when he blows Roy up with dynamite.
* [[WalkingSpoiler A character]] has this in the BlackBoxTV episode [[http://m.youtube.com/watch?v=Gj6IyOrMWnQ The Babysitter.]][[http://blackboxtv.tumblr.com/post/55154471828/j0eygraceffa-the-babysitter-new-blackboxtv Here's a picture.]] Link contains spoilers.
* [[Creator/{{Laina}} The Overly Attached Girlfriend]].

[[folder: Western Animation]]
* The twin kittens in ''Best Ed'' give these all the time, the only time they DROP their smile is at Buddy the Squirrel, who gives an OhCrap moment whenever they do.
* [[spoiler:William Dunbar]], of all people in '' WesternAnimation/CodeLyoko'' displays this while in Lyoko while [[spoiler:possessed by XANA after the ending of the third season.]] This is helped by the fact that he is given a {{BFS}} to use as weapon while backed up by Monsters.
* Fred in the ''WesternAnimation/CourageTheCowardlyDog'' episode "Freaky Fred".
* Many cartoon sharks grin at their victims as they sneak up from behind. For instance, the ''WesternAnimation/FindingNemo'' promotional posters featured a blood-crazed Bruce looming over Dory and Marlin.
** Possibly an example of TruthInTelevision, or, more accurately, Urban Legend In Television. In the past, some people believed that sharks grinned and winked as they moved in for the kill. In actual fact, sharks' jaws swing down and forward to allow them to bite, and a membrane moves to cover their eyes so that they don't get damaged in the assault. [[ThreateningShark The look certainly gives the appearance of a scary grin, which may go some way to explain why sharks are such demonised predators.]] It seems unlikely that anyone being attacked by a shark would care whether it looked like it was grinning or not.
** In a similar vein: [[Literature/MobyDick "I grin at thee, thou grinning whale."]]
* ''WesternAnimation/InvaderZim'' typically dons one of these before unleashing {{doom|yDoomsOfDoom}} on the PunyEarthlings, more-likely-than-not followed by an EvilLaugh.
* Creator/ChuckJones' ''WesternAnimation/HowTheGrinchStoleChristmas'' has the eponymous character grow one that takes up most of his face when he gets the "wonderful, ''awful'' idea!" to steal Christmas.
* Psycho, aka "Smiley," TheDragon from ''WesternAnimation/MaxSteel''.
* Mr. Crocker from ''WesternAnimation/TheFairlyOddParents'' is an expert in these kinds of smiles. That grin is made even funnier when it shatters. Complete with a sound of breaking glass.
* Vendetta from ''WesternAnimation/MakingFiends'' has shown one out of aggression and frustration in the episode Super Evil.
* Duncan from ''WesternAnimation/{{Total Drama|Island}}'' shows these from time to time. More so in the second season.
** [[spoiler: Mike's SplitPersonality Mal]] is also fond of giving them in the fifth season.
* In ''WesternAnimation/AvatarTheLastAirbender'', [[MagnificentBastard Azula's]] iconic PsychoticSmirk [[SanitySlippage gradually morphs into one of these over the course of the last few episodes of the series.]]
** Her father, Firelord Ozai, also sports one in the finale when he's attempting to burn down the entire Earth Kingdom.
* Pinkie Pie gives us an [[http://www.youtube.com/watch?v=B5RWk171beU absolutely terrifying example]] in the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Party of One".
** Later on in Season 2's "Lesson Zero", Twilight Sparkle's SanitySlippage results in a rapidly-worsening succession of disturbing [[TheUnsmile Unsmiles]]. [[http://s3.amazonaws.com/kym-assets/photos/images/original/000/186/252/71479%20-%20Cutie_Mark_Crusaders%20Sweetie_Belle%20animated%20apple_bloom%20cmc%20hi_girls%20insane%20scootaloo%20twilight_sparkle.gif?1318691772 Taken out of context]], these can result in some ''severe'' horror. [[https://www.youtube.com/watch?v=EAkSwmhp2sg This]] is probably the most famous "smile" she gives.
** Discord from Season 2 also gives a nice one when he pretty much Force Chokes the mane cast.
** Then there's Princess Cadence [[spoiler:Actually an impostor]] in "A Canterlot Wedding, Part 1" when she [[spoiler:imprisons Twilight Sparkle.]]
** Trixie gives a nice one in the beginning of "[[Recap/MyLittlePonyFriendshipIsMagicS3E5MagicDuel Magic Duel]]".
** Rarity gives a [[StealthPun pretty]] good one in [[Recap/MyLittlePonyFriendshipIsMagicS4E23InspirationManifestation Inspiration Manifestation]] when she shows off her new dress line she made while under the influence of the eponymous spell.
* During his mental breakdowns Ren of ''WesternAnimation/TheRenAndStimpyShow'' would often sport one of these.
* WesternAnimation/KimPossible herself sported one of these at the end of [[WesternAnimation/KimPossibleMovieSoTheDrama her movie]], [[spoiler:right after she kicked [[EvilCounterpart Shego]] into a high-voltage electrical tower to what seems to be her death, crushed under said tower. However, she [[NoOneCouldSurviveThat survives]], frizzled and still smoking from the electrical shock, but without any major injuries. The shot showing this originally wasn't present, which made it look like Shego was killed. Test audiences were horrified, leading to the inclusion of the shot where she and Drakken are arrested and taken to jail.]]
** She also flashes one to Drakken before flattening him (and not for the first time) as well as to Jim and Tim when she thinks of the idea of soccer being a contact sport, when she thinks of using her SuperSpeed in Queen Bebe, and maybe a few other instances. And she's the ''good guy''.
* WesternAnimation/SpongeBobSquarePants wins a prize. He waits for it at the mailbox for an impossibly long time. He finally gets it, and it turns out to be a toy. Patrick, his idiot starfish friend, "breaks" it. Spongebob just has a frozen smile on his face as he looks down at it. The smile stays on the entire following conversation:
-->'''[=SpongeBob=] & Patrick:''' It's beautiful. (Patrick touches it and its springs pop out)\\
'''Patrick:''' [=SpongeBob=]?\\
'''[=SpongeBob=]:''' I waited so long...\\
'''Patrick:''' [=SpongeBob=]?\\
'''[=SpongeBob=]:''' And you broke it...\\
'''Patrick:''' You okay, buddy?\\
'''[=SpongeBob=]:''' Yes, yes I'm okay.\\
'''Patrick:''' (sighs) For a sec, I...\\
'''[=SpongeBob=]:''' YOU! YOU RUINED MY FREE TOY!!!
** Also, "I'VE BEEN WAITING FOR YOU, PATRICK!!"
* SelfDemonstrating/TheJoker, [[WesternAnimation/BatmanTheAnimatedSeries in]] [[WesternAnimation/JusticeLeague all]] [[WesternAnimation/BatmanBeyond of]] [[WesternAnimation/TheBatman his]] [[WesternAnimation/BatmanTheBraveAndTheBold appearances]]. His good guy counterpart gets one of these in ''Brave and the Bold'', too.
* ''WesternAnimation/LegionOfSuperheroes'': in the episode "Cry Wolf" Timber Wolf did this [[spoiler: showing us that he was [[BrainwashedAndCrazy under the nanite's influence]]]]
** In his debut episode, his [[EvilutionaryBiologist father]] also demonstrated this as he was going through his VillainousBreakdown while [[TheDogBitesBack he released his mutated animals to go after the Legion.]]
* ''WesternAnimation/ReBoot'''s Hexadecimal had many masks with different emotions, with which she expressed herself, but her Slasher Smile mask is arguably the most (in)famous of all. Scarcely an episode went by without her using it at least once, and she always insisted on sticking her face right up against the camera when she used it.
** In the season 2 finale Megabyte gives one to Bob before [[spoiler: launching him into a web portal.]]
* ''WesternAnimation/JimmyTwoShoes'': Heloise, being [[AxCrazy Heloise]], is prone to these. It's strangely adorable on her.
* ''WesternAnimation/EdEddNEddy'': [[spoiler: Eddy's Older Brother]] gives a particularly creepy one [[http://static.tvtropes.org/pmwiki/pub/images/EddysBrother_3006.JPG of these]] in TheMovie.
** In a more comedic example, [[StalkerWithACrush The Kanker Sisters]] were prone to these too.
** So was [[EnfantTerrible Sarah]].
** And Eddy whenever he's cooking up a scam.
** Kevin too, right before he'd beat up one of the Eds.
* ''WesternAnimation/CodenameKidsNextDoor'': The [[CreepyChild Delightful Children]] alternate between giving slasher smiles, psychotic smirks, or just [[DissonantSerenity smiling calmly]]. And yes, it's creepy.
* [[BadPowersGoodPeople Raven]] from ''WesternAnimation/TeenTitans'' dons one of these in "Nevermore", when her emotions and power go out of control.
* Combined with ''WesternAnimation/TheLooneyTunesShow'' song "We Are in Love", [[http://images3.wikia.nocookie.net/__cb20110717204245/looneytunesshow/images/1/1c/Snapshot20110717155807.png it might be hard]] [[http://images1.wikia.nocookie.net/__cb20110717204238/looneytunesshow/images/4/43/Snapshot20110717155804.png to look at Lola the same way anymore]].
* The [[PsychoForHire Grim Reaper]] in ''WesternAnimation/AvengersEarthsMightiestHeroes'' flashes one of these whenever he's about to fight someone. (Or whenever he's beaten them.)
* In ''WesternAnimation/TheSpectacularSpiderMan'', Green Goblin possesses one that is quite creepy combined with his EvilLaugh and [[EvilHasABadSenseOfHumor Sadistic One-Liners]].
* Near the end of an episode of ''WesternAnimation/FamilyGuy'', [[spoiler:New Brian actually does give this when he tells Stewie of him using Rupert the Teddy Bear for his pleasure]], giving out the most evil slasher smile he ever gave.
** Stewie gives one in "A Very Special Family Guy Freakin' Christmas" when he gets his picture taken with Santa.
* Angelica of ''WesternAnimation/{{Rugrats}}'' would sometimes indulge in one of these.
* ''WesternAnimation/DannyPhantom'' villain [[FutureMeScaresMe Dark Danny]] does this quite frequently - it's part of his charm. [[ArchEnemy Vlad Plasmius]] also gives us one from time to time when he's feeling especially deranged, but he mostly sticks to his PsychoticSmirk.
* Wayne Cramp of ''WesternAnimation/TheCrampTwins'' has this as a default expression.
* Try to name someone in ''WesternAnimation/TheVentureBrothers'' who '''hasn't''' done one yet.
* [[EvilCounterpart Kevin 11]] did this ''very'' often in the original ''WesternAnimation/{{Ben 10}}''. He stopped doing this after [[HeelFaceTurn reforming]] in ''[[WesternAnimation/Ben10AlienForce Alien Force]]''... [[spoiler:Then starts doing it again in season 1 of ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]'' after being turned insane again.]]

[[folder:Other]]
* Many of the images on Encyclopedia Dramatica's [[http://encyclopediadramatica.ch/DO_IT_FAGGOT "DO IT FAGGOT"]] page can either be examples of {{Slasher Smile}}s or {{Cheshire Cat Grin}}s.
* In NorseMythology, Loki was often depicted with one of these (in some versions, due to a bet gone wrong Loki often had ''scars'' on his entire lip as well.
* [[http://knowyourmeme.com/photos/60436 Smile.dog's]] nightmarish grin is like this.
* The urban legend of [[TheAdjectivalMan The Grinning Man]], told as an event that coincided with the Mothman sightings in West Virginia during the 1960s. [[http://rookery.s3.amazonaws.com/2452500/2452827_31a7_625x1000.jpg Some artistic renderings]] [[http://otherworldmystery.com/wp-content/uploads/2011/07/grinning-man.jpg can be a little unsettling]].
** The last one... Is that Voldemort?
** That last image may be NightmareRetardant. It's an edited photo of the cockmongler.
*** It's only NightmareRetardant if you actually knew who the cockmongler was before hand. Otherwise?
* Death is usually seen as a skeleton (with some accessories, like a scythe). Ironically, a human skull seems to "smile" all the time.
* Play the ''VideoGame/LunaGame'', [[http://i2.kym-cdn.com/entries/icons/original/000/005/722/TheLuna.png Never sleep again.]]
* [[CreepyPasta Jeff The Killer]]. [[NightmareFuel/CreepyPasta Go to sleep]].
[[/folder]]

[[folder: Real Life]]
* Actor Creator/JackBlack can be seen with these in a wide number of photos.
* The "literally smiling from ear to ear" disfigurement smile as evidenced by characters such as Kakihara in Ichi the Killer, Gwynplaine (of the aforementioned The Man Who Laughs), and ''Film/TheDarkKnight'''s Joker is commonly referred to as a [[http://en.wikipedia.org/wiki/Glasgow_smile "Glasgow]] [[GlasgowGrin smile]]" and is not a terribly uncommon humiliation injury by gangs. The actor [[http://en.wikipedia.org/wiki/Tommy_Flanagan_%28actor%29 Tommy Flanagan]][[note]]Actually from Glasgow, Scotland.[[/note]] sports one of these courtesy of being jumped outside a pub in his younger days.
** In Japan, legends abound of the ''kuchisake-onna'' (口裂け女), a female onryou with a surgical mask to conceal it and who is hellbent on returning the favor to every male she accosts around sundown
* Creator/JackNicholson.
** [[Film/TheShining "Heeeeeeere's Johnny!"]] (that tends to happen when you play those roles).
** ''With new Joker brand I get a grin again and again and again.''
* Creator/CillianMurphy. When he smiles all the cherubic androgyny disappears, and only the creepiness remains. Something about the emptiness of the eyes contributes to the effect.
** Someone hasn't gone to Google--when he smiles ''naturally,'' he looks ''{{Adorkable}}''.
* Creator/LonChaney was a master of this both in and [[http://i.imgur.com/e7zZM4H.jpg out]] of makeup.
* MichaelFassbender. There's a reason everyone on the Internet [[MemeticMutation thinks he's a shark]].
* This kind of smile may have a long history. Among chimpanzees, smiling is a fear or aggression behavior. Maybe it was the same for our ancestors.
* Canines tend to "smile" right before they bite someone. Thus the phrase "never trust a smiling wolf" (or coyote, jackal, etc as the region may require).
* When you're an animal, showing off your teeth is more-or-less baring your weapon.
** This arguably makes humans a {{Proud Warrior Race|Guy}} with [[Music/FallOutBoy weapons in the form of words]].
** Smiling too widely is a good way to unsettle a fencing opponent. A US Olympic saber team apparently got their [[TwinkleSmile teeth made all shiny]] - so the grin would show through the mesh?
** Which is why you're instructed not to bare your teeth when dealing with horses. Horses are prey, and bared teeth might scare them into running away, and in case you didn't know, they're ''big''.
* Dolphins. Don't be fooled by [[CuteIsEvil their adorable appearance]], they're psychotic killers.
* Great White Sharks, the serial killers of the ocean. They actually stalk their prey, just like a serial killer -- or like any natural predator.
* Pittsburgh Steeler receiver Hines Ward is known for two things. The first is blocks so vicious and they made a new rule to try to keep him from hurting people. The second is almost always smiling. No matter how hard he gets hit, or how hard he hits someone, he gets up smiling like a lunatic.
* Mug shot of the Tucson, AZ shooter, [[http://i.i.com.com/cnwk.1d/i/tim/2011/01/11/Jared_Loughner12_244x183.jpg Jared Loughner]], who killed six people and injured fourteen.
* [[MadDoctor Josef Mengele's]] smile, as seen [[http://www.mengele.dk/new_page_2.htm here]], is an absolutely horrifying example if you know of the [[MoralEventHorizon abominable things ]] he did.
* Cult leader and sexual deviant David Berg's slasher smile never seemed to leave his face. Makes you shudder and want to punch him at the same time.
* Creator/MarlonBrando, as seen [[http://images.wikia.com/godfather/images/4/49/Marlon_brando_make_up.jpg here]]. (He looks like he might have been told by the makeup artist to grin so that the artist knows which facial wrinkles to highlight. Still looks freaky.)
* UsefulNotes/JoeBiden smiles a lot: a nice smile, on the whole. But in this smile, as he [[http://www.thedailyshow.com/watch/wed-june-9-2004/finding-memo explains why we have the Geneva Convention,]][[note]]go to 5:15[[/note]] there's nothing but pure distilled rage. And NightmareFuel.
-->To protect ''my son'' in the military. That's why we sign these treaties.
* [[TheFundamentalist Shirley Phelps]] [[http://i.imgur.com/0G2jb.jpg tends to wear this expression during interviews]].
* Snakes are a semi-example; they don't actually smile, but many look like they have a closed-mouthed smile. Both the green and black mamba have this face, and they are not nice snakes at all. Of course, if they ''open'' their mouth, things just get worse.
* Crocodilians. Crocodiles in particular have interlocking teeth which makes it look like they are grinning.
* Actor [[Series/TheAddamsFamily John Astin]] often sports one of these in his various roles.
