Most supernatural monstrosities and [[ScaleOfScientificSins scientific sins]] against nature that maintain a {{Masquerade}} can hide their [[RedRightHand true nature]] with a {{glamour}}, or otherwise {{shapeshift|ing}} into a [[GlamourFailure nearly]] seamless human disguise.

Sometimes, though, they just want to play with their food. They drop the facade and show their true form, [[EyeColourChange getting scary eyes]], growing {{fangs|AreEvil}}, {{horn|edHumanoid}}s, PointyEars and FemmeFatalons or even claws. The changes can range from the purely cosmetic to the practical. In video games or [=RPGs=], this usually affords attack bonuses or new forms of attack altogether. In film, TV, or literature it usually means any InnocentBystanders nearby just dropped a rung in the food chain.

This is a common trick for [[OurVampiresAreDifferent vampires]], [[OurDemonsAreDifferent demons]], [[OurWerewolvesAreDifferent werewolves]], and other [[OurMonstersAreDifferent monsters]]. Think of it as a super-fast OneWingedAngel act, but with typically less power than a full transformation.

TruthInTelevision as many are the small, mostly harmless animals whose only means of defense is to suddenly flash vivid colors or markings, or seemingly double in size, or otherwise appear to suddenly change into frightening monsters. Many of them couple this with [[RoarBeforeBeating making sudden terrifying noises]] for further [[CuteButCacophonic scaring-the-crap-out-of-enemies-ery]].

Compare DemonHead.


[[folder: Anime & Manga ]]
* In ''Anime/DragonBallZ'', Super Saiyans get a lot of use out of this trope, but play it closer to its TruthInTelevision version. They do gain spikier hair and begin glowing vibrant colors & in addition to this they get a massive power up. Some later upgrades even include large muscles, hair and even eyebrows.
* In ''Manga/{{Bleach}}'', the Vizards can put their Hollow masks on as a definite Game Face.
* In ''[[Manga/FullmetalAlchemist Fullmetal Alchemist: Brotherhood]]'', after [[spoiler:Selim Bradley]] reveals his true identity as Pride, he's consistently drawn with sharper features and more menacing eyes instead of the almost chibi appearance he had before.
** Both incarnations of Greed also had a charming, handsome human face (granted, one had pointed teeth), which in a serious fight, would be covered by the demonic, armored face. Being rather vain, Greed ''really'' hated using that form unless he really had to.
* ''Manga/RosarioToVampire'': Absolutely everywhere, given that all of the monsters in it can take a perfect human disguise form, and given that a Global {{Masquerade}} is firmly in effect. [[HornyDevils Succubi]], [[AnIcePerson Yuki'onna]] and [[TakenForGranite Gorgons]] are all good examples of slighter changes (hair turning to ice, lengthening nails and ears or hair turning to snakes) while a great many other monsters show much more drastic change to their true forms. Of course while they are seldom angered enough to do so, the main characters have all shown ability to pull some very scary game faces despite their good natures.
* ''Manga/DeathNote'': Light Yagami does this, having hidden his [[StepfordSmiler true personality]] almost to the very end, he loses what's left of his sanity when he's exposed, and [[EvilLaugh breaks down]] [[MotiveRant and confesses]], as he'd just got done swearing he'd never do. The [[RedOniBlueOni scary red eyes]] are just for us, the audience - but the frightening facial contortions, dramatic gestures and visible madness? Yeah, they're free for all. What makes it a Game Face is that it liberates him to finally state his case in person. [[ShutUpHannibal Not that it convinces anyone]].
* In the ''Anime/DarkerThanBlack'' tie-in manga ''Shikoku no Hana'', Azusa shows Mioka hers while ''casually breaking his shin and asking him if he was showing his''.
-->'''Azusa:''' Is that your game face?
* Parodied in ''Anime/ExcelSaga''. The adorable, teddy-bear like Puchuu's faces resemble ''Manga/Golgo13'' when in pain.
* In ''Manga/SayonaraZetsubouSensei'', Chiri Kitsu normally looks [[http://mundonoes.com/wp-content/uploads/2007/12/chiri.jpg like this]]. However, when she shows her AxCrazy side, [[http://lh3.ggpht.com/_o8ElMaP74s4/SeoDkl7GfcI/AAAAAAAAEEg/lTqtdATIMts/chirizetsubou110.jpg she looks like this.]]
* A rare heroic case in ''Anime/HumanoidMonsterBem'', where all three heroes keep a third of their power locked while in human form.
* ''Anime/PantyAndStockingWithGarterbelt'' features Chuck, resident ChewToy that even ''God himself'' abuses (granted those lightning bolts are to send messages to the protagonists, but still). Then Panty gives him permission to put on the Game Face, and [[spoiler:'''''he turns into a NighInvulnerable [[OhCrap giant regenerating hellhound]]''''']].
* What occasionally happens to Haruko's face in ''Anime/{{FLCL}}'' during fights could be described as this. She gets huge, alien-like eyes and sharp teeth, which may or nay be closer to her original alien appearance.
* In ''Manga/FairyTail'', whenever he gets [[UnstoppableRage angry]], Natsu has two veins that bulge in a diagonal slant above his eyebrows and his eyes change in to pale yellowish color with slit-like pupils.
** A Full-Body Take Over gives Elfman and [[spoiler:Mirajane]] this effect.
* ''Anime/YuGiOh'': Yugi Muto and Pharaoh [[spoiler:Atem]] dueling.
** In ''Anime/YugiohArcV'', whenever Yuya gets angry enough to reveal his SuperpoweredEvilSide [[spoiler:Zarc]], his eyes [[RedEyesTakeWarning glow red]], his hair spikes up, and he gains a dark aura.
* Many Bishokuya from ''Manga/{{Toriko}}'' through their "intimidation", often accompanied by the image of a large terrifying beast.
* Koro-Sensei of ''Manga/AssassinationClassroom'' has a kaleidoscopic array of facial colors to convey his emotions. His game face comes in the form of Pitch Black. [[http://l.mfcdn.net/store/manga/10718/01-001.0/compressed/m039.jpg Extreme anger.]]
* Inverted and subverted in ''Anime/QueensBlade'' with [[BiggerBad The Swamp Witch]], at least in the anime: [[spoiler:Her ghostly looks is the real face of the spirit who controls Werbellia, a demon princess [[GrandTheftMe she's using]] for doing all her atrocities]].
* The Ghouls from ''Manga/TokyoGhoul'' look like completely ordinary humans, but when revealing their true nature gain BlackEyesOfCrazy with [[RedEyesTakeWarning red pupils]] and TaintedVeins around their eyes. They can also extend their kagune, a specialized limb/weapon that has different shapes and properties depending on location and type. Most generally resemble some sort of tentacle or insect wings.
* ''Anime/MiraiNikki'': Murumuru, Deus's [[spoiler: and first world Yuno's, and second world Yuki's]] right hand... demon... gets this when [[spoiler: her bracelets are removed. She then gains superspeed and wild ferocity along with this.]]
* [[OurVampiresAreDifferent Shalltear Bloodfallen]] in ''LightNovel/{{Overlord}}'' normally appears as an ElegantGothicLolita, but when she [[BloodBath bathes in blood]], her {{glamour}} breaks and she turns into what can best be described as a humanoid [[LampreyMouth lamprey abomination]].
* ''Manga/MissKobayashisDragonMaid'': Presented more dramatically in the anime adaptation, when Tohru gets worked up or angry her fingers turn into claws, her eyes become [[HellishPupils even more bestial than usual]], and her teeth turn into fangs. Special mention goes to when she came home to find Kanna clinging to Kobayashi and jumped to the conclusion that the latter was cheating on her.
* The two [[OurVampiresAreDifferent vampire queens]] in ''Anime/BloodPlus'' do it too. When they want to fight, their eyes light up. At Saya they are red and at Diva they are blue.
* In the anime ''Manga/{{Claymore}}'' it is a special case. The faces of the half-human warriornesses change as they use their demonic powers. The more demonic the face of a warrior looks, the more she uses that power, and the stronger she is. However, there is always the possibility that they will lose control of their powers and [[FaceMonsterTurn turn into man-eating monsters]].
* In ''Manga/InuYasha'' it is the eponymous hero who is a [[HalfHumanHybrid half-demon]]. As such, he transforms himself once a month into a human being. But when he is in danger or in great pain, his demonic side gains the upper hand over him, and he gets into [[SuperPoweredEvilSide a wild frenzy]] in which he can no longer distinguish between friends and enemies, and indiscriminately attacks everyone. When he transforms into a pure demon, his eyes turn red, his cheeks give him two violet stripes, and his claws and fangs grow longer.
** It is implied that all naturally-born half-demons have this ability, and also show a similar Game Face in their demonic forms.
* ''Manga/{{Parasyte}}'' has the parasites that infest human bodies and then control them. If they want to fight or kill someone, only their heads change into a monstrous grimace, from which [[CombatTentacles several tentacles with long blades protrude]], the rest of the body remains human.

[[folder: Comic Books ]]
* In ''Comicbook/{{Excalibur}}'', [[FieryRedhead Rachel Summers]] ([[LamarckWasRight avatar of the]] [[BattleAura Phoenix Force]]) gets scary-looking lines on her face when she gets serious. They're actually scars that are always there, and she uses her telepathy to make others see an undamaged face. When she has to use her full power for butt-kicking, she can't spare any for the illusion and lets it drop. Or sometimes she's just too [[HotBlooded pissed off]] to concentrate on it.
* Creator/MarvelComics' nearly-omnipotent pseudo-villain Molecule Man has something (very) similar: a pattern of lightning-shaped scars (caused by the accident which gave him his powers) across his face which seem to appear or disappear when he is either relaxed and mentally balanced, or furious and/or about to break down and cry. As the scars also make his lips appear serrated, it is a pretty creepy game face considering he normally looks rather nerdy.
* Somewhat toned down in ''ComicBook/LesLegendaires,'' where villain Abyss, when revealing his true identity [[spoiler:after posing as Professor Kallisto Vangelis]], gets [[RedEyesTakeWarning Red Eyes]], [[EeriePaleSkinnedBrunette pale skin]] and a SlasherSmile, but otherwise remains quite human-like.
* Bernie of ''ComicBook/DeathVigil'' has one, although the readers [[OffscreenMomentOfAwesome haven't gotten to see it as of this writing]].
* The mages in ''{{ComicBook/Birthright}}'' usually assume a more monstrous and inhuman form when using their magical powers, for example [[KnightTemplar Kylen]] looks like a Caucasian man with blonde hair, but his "mage" form is a bearded, horned demon with purple skin.
* ''ComicBook/JudgeDredd'': While [[DemonicPossession possessing a human host]] in "Dark Justice", Judge Death is disturbed in his work by one of his host's colleagues. He shuts the door and gives the man a brief flash of his skull-face before murdering him.

[[folder:Fan Works]]
* Harry develops this in ''Fanfic/ChildOfTheStorm'', with his eyes [[EyeColourChange alternately flashing gold, or outright burning gold]], with a [[CompellingVoice compelling]], [[VoiceOfTheLegion echoing voice, like two voices speaking at once]] occasionally thrown in for good measure when he wants to ramp up the intimidation. It's generally noted to be extremely unnerving.
* {{Invoked}} by the Night Guard of FanFic/RainbowDoubleDashsLunaverse. In addition to its other functions, their enchanted armor projects a glamor that makes them appear to have slitted eyes, tufted ears, bat wings, and razor-sharp fangs, in order to intimidate enemies.
* [[http://zaifonart.tumblr.com/post/131802014627/i-had-a-thought-what-if-sans-opened-his-teeth This]] spoiler-laden ''VideoGame/{{Undertale}}'' comic shows just how terrifyingly quickly [[spoiler:Sans the skeleton's]] expression can go from 0 to 100.

[[folder:Films -- Animated]]
* Nonvillain example: In ''WesternAnimation/HowToTrainYourDragon'', Toothless got his name because [[spoiler: his teeth are retractable, and he only shows them when he's eating or snarling at something]].
* In ''WesternAnimation/HotelTransylvania'', {{Dracula}} occasionally gets mad and shows his scary face, which involves RedEyesTakeWarning, his fangs for all to see, and menacing growling.
* Princess Unikitty from ''WesternAnimation/TheLegoMovie'' is a cheerful RidiculouslyCuteCritter, but barely 5 minutes of her introduction, we get to see a glimpse of her inner rage, dubbed 'Angry Kitty'. In the climax, she gave into her rage and went onto a rampage.

[[folder:Films -- Live-Action]]
* The Library Ghost's transformation from sweet little old lady to skeletal hag provided one of the first and most memorable scares from ''Film/Ghostbusters1984'', and an unused version of her GameFace was recycled for the [[Film/FrightNight1985 next example]] a year later.
* The ghost of the Aldrich Mansion in ''Film/Ghostbusters2016'' counts as well, looking very pretty until, to quote Holtzmann, "she dislocated her jaw and ectoprojected all over [Erin]."
* ''Film/FrightNight1985'': The vampires Jerry Dandridge and Amy Peterson.
* The vampires in ''Film/FromDuskTillDawn''.
* In ''Film/TheDevilsAdvocate'', several characters associated with [[LouCypher John Milton's]] law firm torment Mary Ann Lomax by revealing their [[NightmareFace true faces]].
* In the Brazilian film ''Film/OAutoDaCompadecida'', Satan stops using his human face and goes into a devilish face (as well as a [[EvilSoundsDeep deep voice]]) after the protagonist angers him enough.
* ''Film/TheLostBoys'': Vampires in general can do this, turning their normally-human features demonic and horrific. A seemingly-innocuous character [[spoiler: (Max)]] turns out to be the BigBad and we don't know it until he gets his Game Face -- but the effect may seem doubly disconcerting since actor [[spoiler: Edward Hermann]] was ''chosen'' to look especially nonthreatening. [[spoiler: James Spader]] in ''Wolf'' is similar. The only vampire who never did this was Star (and she wasn't truly evil).
* ''Film/{{Beetlejuice}}'': If you ever meet Beetlejuice, be sure to ask him "Can you be scary?"
** Barbara and Adam Maitland also learn how to make game faces when they try to remove the Deetzes.
* ''Film/WhoFramedRogerRabbit'': "Remember me, Eddie? When I killed your brother, I talked [[PunctuatedForEmphasis Just.]] LIKE. THIIIIIIS!"
* In ''Film/{{Clash of the Titans|2010}}'' (the 2010 version), [[GorgeousGorgon Medusa]] normally looks [[CuteMonsterGirl very attractive]], but, when using her stone gaze, her face becomes demonic and hideous.
* Played for laughs in ''Film/GalaxyQuest'', where the crew encounters some weird baby-looking aliens on a desert planet. One of the cute aliens gets hurt, and the others crowd around it as if to help it get water... only to reveal demonic faces with terrifyingly sharp teeth and devour the thing alive.
* In ''Film/BloodAndDonuts'', Boya uses his game face to intimidate the gangsters that are harassing him and Earl. Unsurprisingly, it works very well.
* In ''Film/{{Nightbreed}}'', Lori and her boyfriend Eric Boone, now a newly-turned member of the Nightbreed, have escaped Midian and are on the run from the police. When the cops marshal an entire force to arrest him he turns around to show Lori his true face.
* ''Film/{{Hellbound}}'': The demonic villain mostly appears disguised as a human, but every time he kills someone he grows claws, gets frog-like pupils, and [[EvilSoundsDeep his voice drops a few octaves]]. When he's defeated, he briefly [[ThisWasHisTrueForm reverts back to his true form]].
* ''Film/TransformersFilmSeries'' made Optimus Prime's trademark faceplate retractable so it could slide into place for combat (or when suitably dramatic), a trait that's creeped into other incarnations. Some of the other Transformers also have some kind of "battle mask", most notable Bumblebee.
* Large Marge illustrating the truck accident [[JumpScare victim's face]], in ''Film/PeeWeesBigAdventure''. As Pee Wee would discover at the restaurant, that was ''her'' face.
* ''Film/{{Vampirella}}'': Vampirella briefly changes her appearance to make a point to Adam Van Helsing, gaining [[RedEyesTakeWarning red eyes]] and [[FangsAreEvil fangs]] in the process.
-->'''Vampirella:''' This is ''what'' I am. [changes back] And this is ''who'' I am.
* ''Film/CountDracula1977'': Both Dracula, the vampire brides and Lucy (after she's turned) eyes turn completely red when going full vampire.
* ''Film/CountYorga'': When out in the public, Yorga seems like a normal 40 year-esqe man. But when he vamps out, his skin goes much paler, he gains a row of fangs in his mouth and his look turns downright feral. The same applies to his brides.
* ''Film/HanselAndGretelWitchHunters'': {{Inverted|Trope}}. Grand Witches can change ''out'' of their monstrous face and look like a regular (and beautiful) woman. Crosses back to straight since Muriel spends most of the movie looking pretty and dropping the disguise to affect a straight GameFace.

* Veela from ''Literature/HarryPotter'' look very beautiful and can charm men into doing or saying anything to impress them, but when pissed off, they go from beautiful women to hideous avian abominations capable throwing handfuls of fire.
-->'''Arthur Weasley:''' And ''that'', boys, is why you shouldn't marry for looks alone.
* ''Literature/NeedfulThings'': Leland Gaunt. He looks like a charming and handsome man, but he's actually a demon with claws, and a face that is "a horror of eyes and teeth".
* The trolls from ''Twilight Eyes''. They can switch between horror and looking like ordinary humans at will, and to detect them while they look like humans, you need twilight eyes.
* In ''Literature/TheHollows'' series, vampires' eyes go completely black when overcome by bloodlust.
* ''Literature/TheDresdenFiles''
** Red Court vampires are monstrous, bat-winged demons wearing human skins. When things get hairy, the skins come off.
** Harry himself refers to Will and Georgia's shapeshifting into their wolf forms as putting on the game face.
** White Court Vampires look beautiful and pale and when they go Game Face, it's the same, but with a distinctly inhuman bent to it.
*** To be specific, they usually look like pale and beautiful humans with silver-grey eyes. When they get serious, they become inhumanly pale, their eyes glow silvery white and their beauty becomes terrifying as well as alluring. During the one occasion a White Court vampire used her full powers, her entire body glowed silver and Harry himself barely resisted throwing himself at her feet, [[MindRape never mind the actual target of her...abilities]].
** Denarians, Nicodemus aside, each have a personal Game Face.
** According to Murphy in ''Aftermath'', Harry is normally this awkward, geeky, weirdly-dressed smartass. When things get dangerous, he becomes a dark, commanding, imperious figure in the center of both figurative and literal firestorms. Badass doesn't begin to cover it.
** It was revealed that if you ever see pale, lovely Mab with her beautiful green eyes and bright, winter-themed dresses get so pissed off her hair, eyes and clothes turn pure black, with black veins crisscrossing her skin, you better start praying to whatever god(s) you believe in that she spares your life- or at least kills you painlessly.
* ''Literature/{{Discworld}}''
** Wolfgang's pack that, while they find it convenient to hunt in wolf form, are not above frightening peasants.
** [[TheFairFolk Elves]] without their glamours on are also quite frightening. Especially the queen.
*** Usually the elves seem ''less'' impressive with their glamour off, usually described as small, pathetic, dull and gray. There's a deliberate parallel to TheGrays there.
** [[TheGrimReaper Death]] himself, in ''Mort'', when out looking for a new job, has to deal with a clerk who is slightly condescending and who not-so-subtly tells Death that he has no useful skills. Death then forcibly overrides the man's WeirdnessCensor for only a fraction of a second, allowing the man to see Death as wizards and cats are able to. Death then has to deal with a customer who had arrived to complain, eventually giving up and bribing her.
** Speaking of Death, Mort and Susan have a version of this (Mort while he was playing Death's role and Susan on a permanent basis on account of being Death's [[LamarckWasRight granddaughter]]. This involves switching from normal speech to doing [[foldercontrol]]

[[folder: The Voice ]]
and [[/folder]]

[[folder: talking like this ]]
and something frightening happens with their face (probably their skull shows through). It tends to scare most people.
* ''The Literature/SecondApocalypse''
** Kellhus is genius with literally no emotions. However, he has complete control over his entire body, including his facial muscles, so he is able to fake emotions without any difficulty. When someone finally figures out [[MagnificentBastard that he's been manipulating everyone the entire time]] and confronts him about it, every muscle in his face goes ''dead'', like turning off a light.
** Skin-spies are shapechanging assassins with faces that are entirely composed of "fingers" that compress together to form any face they can imagine and allow them to impersonate people. When they drop their disguise, their face falls apart into a mass of wiggling fingers around a blank center.
* Subverted in ''Literature/TheJenniferMorgue'' by Creator/CharlesStross. The protagonist is working with a [[HornyDevils succubus]] covered by a level-three glamour that makes her look like a gorgeous woman. Eventually despite her warnings he insists that she reveal her real face--and instead of the hideous demon he expects, it turns out she's a HalfHumanHybrid that he actually finds rather attractive.
* A non-evil variant in ''Literature/AkataWitch'' by Creator/NnediOkorafor. In it, all Leopard People (people with special magical abilities) have a "spirit face", that is almost like their true form. Seeing another person's spirit face is seen as almost the same as seeing them naked. However, Sunny plays this straight when she gets in a fight with another student and shows them her spirit face to scare them.
* Once the shit has well and truly hit the fan in ''Literature/TheShining'', the Overlook forces Jack Torrence to smash his face in with a croquet mallet, leaving him a faceless meat puppet of the hotel's malevolent spirits.
* Gully Foyle the AntiHero protagonist of ''Literature/TheStarsMyDestination'', a classic sci-fi adaptation of ''Literature/TheCountOfMonteCristo'' by ''Creator/AlfredBester'', had a hideous tiger tattoo across his face. In his more refined state he'd had the tattoo removed. However, it would reappear whenever he became enraged as the blood would pump to his face.
* In ''SheepsClothing'', the three vampires exhibit a form of this when they're hunting. The two brides show off red eyes and a mouthful of fangs, while their sire, Russeau, turns into a monstrous bat.
* In ''Literature/TheGirlFromTheWell'', when Okiku is in a calm and contemplative mood, she wears the appearance of the girl she was in life. When she is stalking a victim, however, her appearance becomes that of a drowned and decaying corpse.
** {{Literature/Sharpe}}: Captain William Frederickson of the Royal American Rifles deliberately plays up his scars for intimidating effect, and always removes his wig, false teeth and glass eye before a fight to make his appearance more frightening.
* The vampires in ''Literature/TheMortalInstruments'' usually drive their fangs out when they want to fight.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer''
** Vampires have a human face, and a demonic face. The demonic face has vaguely bat-like bumps along their foreheads, yellow eyes, and of course, fangs. Some vampires are {{Shapeshifter Mode Lock}}ed into their demon face, such as The Master and Kakistos, presumably because of their extreme age (the Master being identified as the oldest known vampire at the time of his introduction). It's implied that their demon face is stronger, given Buffy told Angel to put his Game Face on during the Season One Finale, and it's confirmed in the spin-off (see below).
** On the flip side, there is {{Dracula}}, who only has a human face but always has fangs. Spike says it's due to gypsy magic, which is the {{handwave}} used to explain all the ways Dracula differs from other Buffyverse vampires.
** The Anointed One is one of the few recurring vampires to never show his, leaving it ambiguous as to whether or not it would've been NightmareRetardant or just silly.
** Vengeance demons as well.
** Willow has two game faces, her lesser used "Light Willow" look and her more well-known "Dark Willow" persona that comes complete with {{black eyes|OfEvil}}, [[PaintItBlack black hair]], and evil face veins.
* ''Series/{{Angel}}''
** The vampires. Angel even keeps it [[HilarityEnsues when turned into a muppet]]. One episode states that he gets stronger with his Game Face, but his bloodlust also increases. Vampires' demonic faces become much worse (and the advantages and drawbacks both get amped up) in the dimension of Pylea, due to its unique metaphysical properties causing hybrid species such as vampires to manifest as either fully human ''or'' fully demon. When Angel changes his face during a fight, he ends up turning into a ferocious demon called a "Van-Tal", the Pylean name for vampires, with green skin, red eyes, and horns. His strength and durability massively increase, but he can barely control his bloodlust in this form and nearly kills all his friends, and when he finally changes back to his human form, he's horrified. It's explained that in Pylea, the demon fully manifests, which means that's the true form of Angelus.
** Doyle has one too; his demon form has green skin and is covered in {{spikes|OfVillainy}}. He's stronger in demon form, but prefers his human form, but this is because he likes to pass for (relatively) human, not due to bloodlust. Played for humor in that Doyle involuntarily shifts to his demon form (though only for a moment) when he sneezes.
** Jasmine, with her maggoty, revolting true face and her beautiful false one.
* Vampires in ''Series/{{Being Human|UK}}'' ([[Series/BeingHumanUS both versions]]) normally look completely human, but when about to bite people or otherwise get violent, their eyes turn solid black and their fangs come out. They're also able to consciously activate this when they aren't being violent, but still want to scare people.
* ''Series/{{Supernatural}}'':
** Demons possessing a person's body look exactly the same as a regular human, except when their eyes go [[BlackEyesOfEvil solid black]]. Used quite often as a [[RevealShot dramatic reveal]] on the show.
** The Leviathans, also body-hijackers, would show their true form whenever they would devour people, with their face splitting open to reveal a [[MoreTeethThanTheOsmondFamily gaping jaw lined with hundreds of teeth]].
* ''Franchise/KamenRider''
** In ''Series/KamenRiderFaiz'', an Orphnoch will typically show a shadowy version of its transformed state over its face as a way of saying "don't screw with me." This isn't the actual [[OneWingedAngel battle mode]], though (''that'' would be a full transformation into the [[PeopleInRubberSuits rubber suit]], which ''starts'' with the 'game face' appearing.)
** ''Series/KamenRiderKiva'': The red and blue vein-like lines on a Fangire's neck and lower face before transforming.
** ''Series/KamenRiderWizard'': The Phantoms do a combination of both the Orphnochs' and Fangires' Game Faces (a shadowy aura of the monster face over their human forms before turning into their true forms).
** Ironically, ''Series/KamenRiderAgito'' had a heroic variation. Another Agito would proceed his [[FinishingMove Rider Kick]] by retracting his mouthplate to reveal a skeletal mouth underneath.
* In the episodes "The Impossible Planet"/"The Satan Pit" of ''Series/DoctorWho'', a person who has been taken over by the alien of the week will have red eyes (red eyes only for the Ood) and mysterious writing tattooed on their skin [[IncrediblyLamePun (including their faces)]] as well as an I-will-hurt-you expression in general, complete with narrowed eyes and a mischievous grin.
* ''Series/TheVampireDiaries'':
** Vampires get writhing, black TaintedVeins around their eyes (the whites of which turn [[RedEyesTakeWarning red]]), in addition to growing fangs, when they exhibit bloodlust.
** Werewolves have a slightly more subtle version of this; whenever their werewolf side manifest outside the full moon, the only physical change they go through is [[SupernaturalGoldEyes yellow, wolf-like eyes]]. When the full moon does happen however, one of the first signs they are transforming is getting these eyes ''plus'' fangs.
** The season 2 finale and season 3 introduce vampire-werewolf hybrids, whose game faces combine the TaintedVeins and Red Sclera of the former, the yellow irises or the latter, and a double set of fangs from both.
* ''Series/{{Moonlight}}'' vampires extend fangs and morph into slightly-beastly faces in a split-second. When dehydrated, their eyes turn yellow.
* Henry Fitzroy in ''Series/BloodTies'' extends fangs, and his eyes go black. The eyes also go black during hypnosis.
* Vampires in ''Series/{{Sanctuary}}'' gain slanted black eyes, long talons on their fingers, a full mouth full of fangs and deeper voices when they shift into vampire mode. Tesla's skin also became grey on the first occasion he shifted, but this was largely ignored during later transformations.
* In the ''Series/LostInSpace'' episode “The Golden Man” (Season 2, Episode 15), Mr. Keema proposes to Dr. Smith that in exchange for the weapons from the Jupiter 2 to defeat his enemy the frog faced alien, he will transport Doctor Smith back to Earth. Dr. Smith brings the weapons without permission. As he is talking to the handsome alien about extending the hand of friendship, Mr. Keema transforms himself into his twisted ugly self and then tells Smith that after he disposes of the frog alien, he intends to destroy the earthlings.
* ''Series/{{Charmed}}'' has half demon-half human hybrids able to do this. Cole has a human form but has to embrace his demon self fully if he wants to tap into his powers. The demon self comes complete with red skin and black tribal markings. One MonsterOfTheWeek has the same appearance in demon form, but with the colors inverted.
* All Wesen in ''Series/{{Grimm}}'' have this, which is how they are recognized by Grimms and each other. Normal (non-Grimm) humans still can't see it unless the Wesen want them to. The latter is called "woging" (pronounced with a "v") from German "woge" meaning "wave". Interestingly, while Grimms don't have a GameFace, their obvious reaction to a Wesen briefly showing theirs is what gives the Grimms away (the Wesen know when they're woging).
** The last part was {{RetCon}}ned into the Grimms having BlackEyesOfEvil that can only be seen by a woged Wesen. The eyes reflect the Wesen's true nature back at it, although sunglasses block the effect.
** An episode deals with the side effects of a Wesen being forced to go "full woge" (i.e. being seen by all) frequently, eventually causing the Wesen to start losing control over his Wesen nature and occasionally going into "full woge" without meaning to and amping out his aggression UpToEleven.
* ''Series/TeenWolf'':
** While werewolves do have a WolfMan form, they can occasionally manifest their powers in a less visible version, which has them grow fangs, claws and [[GlowingEyesOfDoom glowing eyes]] (said eyes being [[RedEyesTakeWarning red]] for [[MonsterLord Alphas]], [[SupernaturalGoldEyes yellow]] for most Beta/Omega, and [[IcyBlueEyes blue]] for non-Alphas who killed someone), but otherwise keep a human appearance.
** The Kamina (AKA [[spoiler:Jackson]]) in season 2 tends to get [[HellishPupils yellow, reptilian eyes with slitted pupils]]) whenever he is still in human form yet being controlled by his master. He can also still manifest his poisonous claws without fully transforming.
** Played with regarding the [[{{Druid}} Darach]] in season 3, who appears as a bald, hideously scarred humanoid on occasion. The twist to this trope is that [[spoiler:this appearance isn't of supernatural origin; it's her real, human face which she got disfigured in her backstory, and she is using {{Glamour}} magic to make herself appear as she was before the incident.]]
* ''Series/ForeverKnight'' vampires get golden eyes and their fangs, which are normally not visible, appear in the mouth. If it's dark, the eyes can appear to glow.
* ''Series/{{Witchblade}}'': During the climactic fight between Sara and Gallo in the pilot, his face briefly morphs into a demonic grin after he tells her that killing her is NothingPersonal to him. This weird hint that he's NotEvenHuman is then dropped completely, as it's never brought up in later episodes.
* Angels and demons in ''Series/{{Lucifer}}'' always appear on Earth in human guise but they can reveal their true form if they wish to.
** Lucifer's face is a bit like a melted Darth Maul and seems to come with a side effect of making people absolutely certain of his identity, which managed to drive one person insane and nearly do the same to another. However, if someone has already been to Hell, his face has absolutely zero effect on that person.
** Maze's face looks about the same as in the original comic, half skull and half human. Trixie thinks its awesome.
* Some mutants in ''Series/TheXFiles'' also can change in this way.

* The Irish folk hero Cuchulain had his "warp spasm," which is lovingly and nauseatingly described in Literature/TainBoCuailnge. You can read the relevant part [[http://benedante.blogspot.com/2011/02/who-or-what-is-cuchulainn.html here.]]

[[folder: Newspaper Comics ]]
* In ''ComicStrip/{{Candorville}}'', [[spoiler:vampires]] have several levels of Game Face. The lowest has CuteLittleFangs. The highest [[spoiler:LooksLikeOrlok]] and has {{red eyes|TakeWarning}}. Incidentally, this seems to differ from one character to another--it may be that the oldest are the ugliest, or that [[spoiler:Saxon's {{Dhampyr}} status is why he gets MilkyWhiteEyes instead of red ones.]]
* ''ComicStrip/{{Garfield}}''
** Garfield uses one on Halloween to scare trick-or-treaters. Unfortunately, true to his mother's warnings, it sticks.
** In one series of strips, Garfield is talking to a mouse who poses for anti-vermin ads for a living. When Garfield asks how ("A cute mouse like you?") the mouse assumes a vicious Game Face. ("That's pretty good," says Garfield.)
** [[CuteKitten Nermal]] has an "extra-cute" Game Face to pose for cat food ads. ("Cute is my life" he says.)

* In ''Pinball/BramStokersDracula'', whenever you get Bat Mode, Dracula will turn into his bat form. When you get all the castle locks, the brides will show their monstrous faces.

[[folder: Tabletop Games ]]
* ''TabletopGame/TheWorldOfDarkness'' games are full of monsters that look like normal humans until it's time to [[LetsGetDangerous get dangerous]].
** Werewolves and other shapeshifters have several {{Game Face}}s somewhere between man and their animal form, up to the ultimate Crinos (or [[TabletopGame/WerewolfTheForsaken Gauru]], or whatever) man-wolf (or whatever half-animal) form. But in ''TabletopGame/WerewolfTheApocalypse'' they can't display the Game Face to ordinary humans -- there's a thing called Delirium, which instinctively makes the human explain away or forget what they saw, and potentially go a little insane as well. In Forsaken, they will go insane most of the time(temporarily) but there's a small chance they can turn into a wolf-blooded or remember it. Furthermore, there are some powers that allow you to control it in a way
** ''TabletopGame/OldWorldOfDarkness'':
*** [[TabletopGame/VampireTheMasquerade Vampires]] can extend their fangs at will, but, depending on their Discipline set, can turn into wolves, hideous monstrosities, or even snakes. It has been speculated that [[ScaledUp turning into a snake never helps]]. The most common "Game Face" among the Kindred is the Presence power "Dread Gaze," which serves to terrify the hell out of most of the mortals that vampires encounter.
*** TabletopGame/KindredOfTheEast, the East Asian counterparts to western vampires, have even more and increasingly bizarre demon forms.
*** Fomori, being corrupt nature spirits inhabiting human bodies, can take a Merit that allows them to hide their powers and putrescence, but generally they are always in their Game Face.
*** [[TabletopGame/DemonTheFallen Demons]] all have Apocalyptic Forms that resemble either angels or demons, depending on how Tormented the demon in question is. The transformation is instantaneous, but might not happen at all if witnessing humans' disbelief is strong enough.
*** [[TabletopGame/WraithTheOblivion Wraiths]] with the Moliate Arcanos can reshape their Corpus into an armored and weaponized war form; however, this is usually unsubtle as all hell. However, the Masquers Guild, who specialize in Moliate, can learn a trick that allow them to craft a normal Corpus "sleeve" onto someone who's been crafted for war, so that they look perfectly normal - only to rip the skin off when damage needs to be done.
** In the ''TabletopGame/NewWorldOfDarkness'':
*** [[TabletopGame/MageTheAwakening Mages]] can draw on the Supernal Realm to increase their Aura and cause an effect like this. The precise appearance varies depending on the Mage's Path. Thyrsus (Shamans) make everything around them seem alive, while Mastigos (Warlocks) can make things go dark and sound like howling demons.
*** [[TabletopGame/ChangelingTheLost Changelings]] can burn all their Glamour at once in order to drop [[LieToTheBeholder the Mask]] and reveal what they truly look like. This is not a recommended course of action, as now you're all out of magic juice, people will likely think you're a monster, and doing so risks damaging the SanityMeter. The only real feasible use of this tactic is if you're a low-Clarity Autumn Court member who then proceeds to [[EmotionEater feed on their tasty, tasty fear]]. There are, however, Contracts that will allow a similar effect without risking your mental stability.
*** [[TabletopGame/VampireTheRequiem Vampires]] with the Nightmare Discipline have Game Face as a starting power - Monstrous Countenance, which allows you to unleash the full and terrible visage of [[EnemyWithin the Beast]]. Most mortals flee on sight. In the Second Edition, one of the possible [[WeaksauceWeakness bans]] they can develop, "Face of Hunger", also causes them to develop an obviously monstrous face (typically [[RedEyesTakeWarning red eyes]] and more corpse-like features) whenever they are starving.
*** [[TabletopGame/DemonTheDescent Demons]] can assume their true forms at will. Like their [=oWOD=] counterparts, they resemble angels or demons - though it's not dependent on their psyche - and add biomechanical horror to the mix as well. However, doing so is risky, as it may draw the attention of their former master, the God-Machine.
* ''TabletopGame/FengShui'''s monsters all have a horrific appearance, and monsters (both [=PCs=] and bad guys) can choose to take a Creature Power called "Brain Shredder," which basically provides one of these and weaponizes it to cause damage through fear.
* TabletopGame/{{Scion}} actually has an Appearance knack called Game Face. This is when a beautiful Scion (ugly Scions have their own knack) has decided they have had enough of their enemy's BS and flash their best [[SlasherSmile I'm-going-to-kill-you grin]] or [[TranquilFury grit their teeth in stony determination.]] Most {{Mooks}} flee on sight and those who don't have to struggle to hold their ground.
* The Dawn Caste Solar anima power in ''TabletopGame/{{Exalted}}'' includes an effect of this sort. It causes the Solar to appear larger, more glorious, and terrifying with GlowingEyesOfDoom and a fully active BattleAura. Interestingly, this particular Game Face can be both activated deliberately or go off on its own simply through expending enough power in combat.
** The Dusk Caste Abyssals and Slayer Caste Infernals, as counterparts to the Dawns, have a similar power.
* ''[[TabletopGame/DungeonsAndDragons Dungeons & Dragons 3.5th Edition]]'' had Pale Night, an ancient demon/EldritchAbomination. She's apparently so evil that ''reality itself has to shield itself from her.'' Evil enough that her strongest attack is to show her face, instantly killing all but the strongest-willed, and even those that survive do so by not comprehending her true form.
** Shifters, from the ''TabletopGame/{{Eberron}}'' campaign setting, have a small touch of lycanthrope heritage. For a brief time each day, they can "shift" into a slightly bestial but physically more powerful form.
** D&D also has a monster called a Krenshar that looks like a type of great cat, but it has very loose skin around its face. Thus, when it wants to scare off predators, is ''turns its face inside out''.
* The... the ''[[CrapsackWorld everything]]'' in ''TabletopGame/{{KULT}}''. {{Justified|Trope}}, as reality is a lie and literally everything isn't what they seem to be.
* Lahmian- and Von Carstein-clan Vampires in ''TabletopGame/WarhammerFantasy'' are often said to be extremely beautiful and/or handsome. You would never tell this by the models, because they're always sculpted with their Game Faces on.

[[folder: Video Games ]]
* ''VideoGame/BlazBlue'': The main villain in once his identity is revealed. [[spoiler: With CompressedHair!]]
* Several of the villains in ''VideoGame/FinalFantasyTactics'' transform into their Lucavi forms for the final confrontation against you. Oddly, the demon forms are often ''easier'' to beat than the human ones, particularly [[spoiler:Elmdore and his Assassins]].
* Mimi from ''VideoGame/SuperPaperMario'' is a {{shapeshift|ing}}er, but usually just looks like a cute green-skinned girl with pigtails and an UnlimitedWardrobe. That is, until you [[http://www.youtube.com/watch?v=2DxHeXQWAdk#t=3m20s actually fight her]] and she transforms into a monstrosity akin to ''Film/TheThing1982''.
* In the latest ''VideoGame/WorldOfWarcraft'' expansion, the [[OurWerewolvesAreDifferent Worgen]] shift into animalistic form whenever they enter combat, including a permanent scowl.
** Interestingly, Worgen can maintain human form while casting healing and buff spells out of combat. Trying to aid an ally currently in combat will trigger the shift, however.
* Scarfy in the ''Franchise/{{Kirby}}'' games is a cute little flying critter that changes into a furious, one-eyed ActionBomb.
* [[spoiler:Matt Engarde]], the killer in the last case from ''VisualNovel/PhoenixWrightAceAttorneyJusticeForAll'', looks nice enough... but when he drops the act, he flips his hair, revealing the [[GoodScarsEvilScars scars over his left eye,]] and his expression becomes a perpetual sneer. [[{{Narm}} Some people find him to look a bit too much like a generic cartoon villain, however.]]
* ''VideoGame/{{Tekken}}'''s Angel has one in the second Tag game. [[GoodIsNotSoft If]] you [[http://images.wikia.com/tekken/en/images/8/8a/Angry_Angel.png see]] it, she's probably about to [[EyeBeams melt]] '''''[[Film/RaidersOfTheLostArk your]]''''' face.
* The ''Franchise/MortalKombat'' series: Reptile, who usually displays a perfectly normal - if half-masked - human face, momentarily flashes a leering [[ScaledUp reptilian]] expression when he [[EyeScream spits green venom into the eyes of his opponents]] or [[BrainFood eats their head.]]
* Several animatronics in the ''VideoGame/FiveNightsAtFreddys'' series have differences between their normal appearance and their appearance while stalking or attacking the player, usually that their eyes turn into BlackEyesOfEvil. Second game's Toy Chica takes it even further as her ''beak'' also vanishes when she is on the prowl. [[http://orig04.deviantart.net/afde/f/2014/356/b/e/profile_picture_by_cupcak_es-d8ar1c9.png Here]] is Toy Chica in her normal state. And [[http://img4.wikia.nocookie.net/__cb20141111101405/freddy-fazbears-pizza/images/7/7c/ToyChicaInTheAirVent.png here]]... is Toy Chica on the hunt...
* In ''VideoGame/SonicAdventure2'', there are the boos - the Normal Boos and the Boom Boos. They start off as seemingly harmless with their black eyes and stitched up mouths, but get close to them or attack them and they will reveal themselves as the Attack Boos which have yellow eyes and sharp-teethed grins (for the Normal Boo, they reveal themselves by {{jump scar|e}}ing a character).
* ''VideoGame/{{Undertale}}'':
** It's subtle but quite startling when facing [[spoiler:Sans on a Genocide Run]] to suddenly see his eyes just disappear with no warning when upset, with the rest of the face unchanged. [[spoiler:As a skeleton this actually gives him a ''more'' eerie and skeletal look, contrary to his [[ExpressiveSkull normally expressive skull face]].]] He actually does this a few times on other kinds of playthroughs, for dramatic effect.
** When facing off against Asgore, he lowers his head, which hides his eyes and makes his hair and beard look more [[BarbarianLonghair barbarous]]. [[spoiler:In actuality, it's because he can't bear to look you in the eyes.]]
** Flowey reveals his as early as he's introduced, in his EstablishingCharacterMoment. Whether you avoid his "friendliness pellets" or run into them, he'll let out an EvilLaugh as he prepares to kill you with an unavoidable circle of bullets.
* While all of the ghosts in ''VideoGame/{{Wick}}'' are already creepy to look at (with the exception of Benny and Lillian), they all start sporting rot and mutilations in the ''No Way Out'' DLC. This may be because where the base game is just avoiding them as part of TheDare, the object of NWO is to ''deliberately fuck with these unquiet dead by messing with their stuff.''

[[folder:Visual Novels]]
* Members of the Berserker class in ''VisualNovel/FateStayNight'' have a Game Face applied as part of their Mad Enhancement. Case in point: [[http://images2.wikia.nocookie.net/__cb20111103162904/typemoon/images/7/71/MadEnhancement.jpg fourth Grail War Berserker (spoilers).]]

[[folder:Web Comics]]
* ''Webcomic/LookingForGroup'': "And Maikos?...[[http://lfgcomic.com/page/253 This is no time for masks."]]
* ''Webcomic/{{Goblins}}'': The titular goblins, like many above examples, have eyes that go solid black when their game faces come on.
* Heroic example from ''Webcomic/{{Misfile}}'', when it's time to do the hero stuff the angels break out their Halos and Wings.
* ''Webcomic/HannaIsNotABoysName'': Casimiro turns into some kind of bleach-white skeletal bat-person thing [[http://hanna.aftertorque.com/?p=571 when he's threatening Hanna]], which may be on purpose to intimidate him or just because the guy's a MoodSwinger.
* In ''Webcomic/GunnerkriggCourt'', Jeanne's ghost, despite superficially resembling her living self most of the time, has a rather terrifying visage while she's in killing mode. She's been down there so long that her ''ghost'' has started to rot.
* At least some vampires in ''Webcomic/SluggyFreelance'' can switch between normal human and pale, pointy-eared, glow-eyed appearances. Hell Mouth and Vrykolakas vampires seem to look unusual all the time, but at least Lysinda Circle vampires have this power. In "Boys' Night Out", Torg is shown with the same kind of appearance change even though he only ''thinks'' he's become a vampire.
** Chapter 68 shows a Lysinda Circle vampire magically adopting different appearances, at least in other people's eyes, so perhaps these vampires are using this power to appear normal when pretending to be human.
* Vampires in ''Webcomic/{{Zelfia}}'' have a [[Series/BuffyTheVampireSlayer Buffy]]-inspired game face.
* A thing with vampires in ''Webcomic/TheNightBelongsToUs''. Ada [[http://tnbtu.com/comic/05-13/ is afraid hers will scare Hank.]]

[[folder:Web Original]]
* ''Literature/WhateleyUniverse'': Like Leland Gaunt, Carmilla only ''looks'' human. She's a budding cosmic entity. In "The Turks and the Geek", she holds Shadowolf with dozens of tentacles and splits her face open down the middle, revealing something so horrific that he wets himself.
* There is a meme called "Show Me Your War Face," which is quite close to this. It became deadmeme when the faces chosen were just derpy enough to miss the target for over-the-top-hamminess, and people left it alone. There were some good ones, though, and they were usually screen caps of a Game Face. Others just ''were.''

[[folder:Western Animation]]
* Raven from ''WesternAnimation/TeenTitans'' is the HalfHumanHybrid daughter of an immensely powerful demon. A word of advice: if you ever see her suddenly sporting four [[GlowingEyesOfDoom glowing]] [[RedEyesTakeWarning red eyes]], ''run''. Not that it'll help much.
* ''Lots'' of ghosts in ''WesternAnimation/TheRealGhostbusters'' can put on a Game Face (if not an outright OneWingedAngel). A ghost might look harmless (in fact, it might pretty-much ''be'' harmless) but it might be able to make its features horrific to scare humans. (Ghosts like to do that, after all.) Even Slimer was able to do it in one episode.
* ''WesternAnimation/CodenameKidsNextDoor'': Make Numbuh Three angry enough and she'll put one on with FireballEyeballs and ScaryTeeth, enough to make even ''her allies'' run for cover (to say nothing of the villains).
* As opposed to the black eyes of the [[WesternAnimation/TeenageMutantNinjaTurtles1987 1987 series]] and the BlankWhiteEyes seen in most of the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 series]], the Turtles of [[WesternAnimation/TeenageMutantNinjaTurtles2012 the 2012 series]] have colored eyes most of the times and get the BlankWhiteEyes when they're being particularly ninja-y.
* The Godpidgeon from ''WesternAnimation/{{Animaniacs}}'' can make his face horrific and scary if he has to. In one episode, he scared the hiccups out of Squit this way.

[[folder:Real Life]]
* As mentioned above, real animals do this all the time, usually by making themselves look bigger. For example, cats arch their backs and make their fur stand up, pufferfish suck up water to inflate themselves, and cobras look like any other snake until they open their telltale hoods for intimidation purposes. Seeing a guinea pig fluff up to look intimidating is probably one of the [[SugarWiki/FunnyMoments funniest]] things in nature.
* [[PrimalStance Hunch over. Bare your teeth. Raise your hands up in position that makes you look like you're about to grab whatever's in front of you.]] Watch pets ''and'' people cower and run as you approach them.
** A more subtle version is for people to hold up their heads, puff out their chests, and hold their arms out slightly in a sort of body builder pose. There is a whole stereotype about short people who use this to try and compensate around taller people, to varying degrees of success.
** Even our unconscious physiology plays a part in this trope, as people who are enraged experience a rush of blood to the skin that can turn one's face and neck more reddish and make veins in the eyes stand out. This plus enlarged pupils offer visible signs that someone is genuinely ''furious'', not just bluffing or performing as such.
* An excellent juxtaposition between Game Face (predation front) and play face (social front) can be seen [[http://www.ted.com/talks/stuart_brown_says_play_is_more_than_fun_it_s_vital.html seen at TED]] during Stuart Brown's lecture on ''Serious Play'' in the interactions between a polar bear and a wolf. The scenario is at 00:01:27.
* Behold the [[http://youtu.be/xVevkHXzy3Y Eastern Hognose Snake]], a harmless, even comical-looking serpent that puts on a heck of a show if anyone tries to eat it.
* Considered to be a big reason why Armadillos are known as "Texas Speedbumps". They have poor eye-sight, so when they suddenly realize an automobile is bearing down on them, they rise up on their hind legs to be more intimidating. [[MuggingTheMonster Which makes them just as tall as the car's bumper.]]
* Horny toads (okay, okay, [[http://en.wikipedia.org/wiki/Desert_horned_lizard desert horned lizards]]) are rather known for this. When threatened, they will not only puff themselves up to appear larger, they also [[TearsOfBlood squirt blood out of their eyes to ward any attacker off.]]
