Game Face

Most supernatural monstrosities and scientific sins against nature that maintain a Masquerade can hide their true nature with a glamour, or otherwise Shape Shift into a nearly seamless human disguise.

Sometimes though, they just want to play with their food. They drop the facade and show their true form, getting scary eyes, growing Fangs Are Evil, horns, Pointy Ears and Femme Fatalons 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 Innocent Bystanders nearby just dropped a rung in the food chain.

This is a common trick for vampires, demons, werewolves, and other monsters. Think of it as a super-fast One Winged Angel act, but with typically less power than a full transformation.

Truth in Television 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 making sudden terrifying noises for further scaring-the-crap-out-of-enemies-ery.

Anime & Manga
"Azusa: Is that your game face?"
 * Dragon Ball Z abused this trope from the Namek Saga onward.
 * In Bleach, the Vizards can put their Hollow masks on as a definite Game Face.
 * In Fullmetal Alchemist: Brotherhood, after  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.
 * Rosario to Vampire: 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. Succubi, Yuki'onna and 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.
 * Death Note: Light Yagami does this, having hidden his true personality almost to the very end, he loses what's left of his sanity when he's exposed, and breaks down and confesses, as he'd just got done swearing he'd never do. The 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. Not that it convinces anyone.
 * Lelouch of Code Geass relies on his featureless mask to preserve his Villain With Good Publicity status. Without the mask he's as persuasive as Light.
 * In the Darker Than Black tie-in manga Shikoku no Hana, Azusa shows Mioka hers while casually breaking his shin and asking him if he was showing his.


 * In Sayonara Zetsubou Sensei, Chiri Kitsu normally looks like this. However, when she shows her Ax Crazy side, she looks like this.
 * A rare heroic case in Humanoid Monster Bem, where all three heroes keep a third of their power locked while in human form.
 * Panty and Stocking With Garterbelt features Chuck, resident Chew Toy 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.
 * What occasionally happens to Haruko's face in 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 Fairy Tail, whenever he gets 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 this effect.
 * Yugi Muto and Pharaoh dueling.

Comic Books

 * In Excalibur, Rachel Summers (avatar of the 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 pissed off to concentrate on it.
 * Marvel Comics' 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 Les Legendaires, where villain Abyss, when revealing his true identity, gets Red Eyes, pale skin and a Slasher Smile, but otherwise remains quite human-like.

Film

 * Fright Night: The vampires Jerry Dandridge and Amy Peterson.
 * The vampires in From Dusk Till Dawn.
 * In The Devils Advocate, several characters associated with John Milton's law firm torment Mary Ann Lomax by revealing their true faces.
 * In the Brazilian film O Auto da Compadecida, Satan stops using his human face and goes into a devilish face (as well as a deep voice) after the protagonist angers him enough.
 * The Lost Boys: A seemingly-innocuous character  turns out to be the Big Bad and we don't know it until he gets his Game Face -- but the effect may seem doubly disconcerting since the original actor was chosen to look especially nonthreatening.   in Wolf is similar.
 * Beetlejuice: If you ever meet Beetlejuice, be sure to ask him "Can you be scary?"
 * Who Framed Roger Rabbit: "Remember me, Eddie? When I killed your brother, I talked Just. LIKE. THIIIIIIS!"
 * Nonvillain example: In How to Train Your Dragon, Toothless got his name because.
 * In Clash of the Titans (the 2010 version), Medusa normally looks very attractive, but, when using her stone gaze, her face becomes demonic and hideous.
 * Senator Palpatine in Star Wars: Revenge of the Sith, after using his Force Lightning.
 * Played for laughs in Galaxy Quest, 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.

Literature

 * Needful Things: 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.
 * Vampires in The Hollows series eyes go completely black and their fangs extend when overcome by bloodlust.
 * The Dresden Files
 * 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.
 * 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.
 * Discworld
 * Wolfgang's pack that, while they find it convenient to hunt in wolf form, are not above frightening peasants.
 * Elves without their glamours on are also quite frightening. Especially the queen.
 * 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 Weirdness Censor 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 granddaughter. This involves switching from normal speech to doing and  and something frightening happens with their face (probably their skull shows through). It tends to scare most people.
 * The Second Apocalypse has Kellhus, a 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 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.
 * Subverted in The Jennifer Morgue by Charles Stross. The protagonist is working with a 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 -- instead of the hideous demon he expects, she turns out she's a Half Human Hybrid that he actually finds rather attractive.
 * A non-evil variant in Akata Witch by Nnedi Okorafor. 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.

Live Action TV

 * Buffy the Vampire Slayer
 * Vampires have a human face, and a demonic face. The demonic face has bumps along their foreheads, yellow eyes, and of course, fangs. Some vampires were Shapeshifter Mode Locked 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 Xander 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 was Dracula, who had only a human face -- but had perpetual fangs. Spike said it was due to gypsy magic, which was the Hand Wave used to explain all the ways Dracula differed from other Buffyverse vampires
 * 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 of Evil, black hair, and evil face veins.
 * Angel
 * The vampires. Angel even kept it 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. Angel changes his face during a fight, and turns into a ferocious demon with green skin, red eyes, and horns. His strength and durability massively increased, but he could 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.
 * Doyle had one too; his demon form has green skin and is covered in Spikes of Villainy. 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 would involuntarily shift to his demon form (though only for a moment) when he sneezed.
 * Also Jasmine, with her maggoty, revolting true face and her beautiful false one.
 * Vampires in Being Human 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.
 * Supernatural: Demons possessing a person's body look exactly the same as a regular human, except when their eyes go solid black. Used quite often as a dramatic reveal on the show.
 * Kamen Rider
 * In Kamen Rider 555, an Orphenoch 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 battle mode, though (that would be a full transformation into the rubber suit, which starts with the 'game face' appearing.)
 * Kamen Rider Kiva: The red and blue vein-like lines on a Fangire's neck and lower face before transforming.
 * In the episodes "The Impossible Planet"/"The Satan Pit" of Doctor Who, 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 (including their faces) as well as an I-will-hurt-you expression in general, complete with narrowed eyes and a mischievous grin.
 * The Vampire Diaries: vampires get veiny around their eyes and grow fangs when they exhibit bloodlust.
 * Moonlight vampires extend fangs and morph into slightly-beastly faces in a split-second. When dehydrated, their eyes turn yellow.
 * Henry Fitzroy in Blood Ties extends fangs, and his eyes go black. The eyes also go black during hypnosis.
 * Vampires in 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 occassion he shifted, but this was largely ignored during later transformations.
 * In the Lost in Space 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.
 * 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.

Mythology

 * The Irish folk hero Cuchulain had his "warp spasm," which is lovingly and nauseatingly described in Tain Bo Cuailnge. You can read the relevant part here.

Newspaper Comics

 * In Candorville, have several levels of Game Face. The lowest has Cute Little Fangs. The highest  and has Red Eyes Take Warning. Incidentally, this seems to differ from one character to another--it may be that the oldest are the ugliest, or that

Tabletop Games

 * The World of Darkness games are full of monsters that look like normal humans until it's time to get dangerous.
 * Werewolves and other shapeshifters have several Game Faces somewhere between man and their animal form, up to the ultimate Crinos (or Gauru, or whatever) man-wolf (or whatever half-animal) form. But in Werewolf: The Apocalypse 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.
 * Old World of Darkness:
 * 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 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.
 * Kindred of the East, 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.
 * 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.
 * In the New World of Darkness:
 * 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.
 * Changelings can burn all their Glamour at once in order to drop 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 risk damaging the Sanity Meter. The only real feasible use of this tactic is if you're a low-Clarity Autumn Court member who then proceeds to feed on their tasty, tasty fear.
 * Feng Shui'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.
 * 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 I'm-going-to-kill-you grin or 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 Exalted includes an effect of this sort. It causes the Solar to appear larger, more glorious, and terrifying with Glowing Eyes of Doom and a fully active Battle Aura. Interestingly, this particular Game Face can be both activated deliberately or go off on its own simply through expending enough power in combat.
 * 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 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 everything in KULT. Justified Trope, reality is a lie and literally everything isn't what they seem to be.
 * Lahmian- and Von Carstein-clan Vampires in Warhammer Fantasy 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.

Video Games

 * The killer in Persona 4 does this when you've figured out who he is. The change in his expression as he gleefully and self-righteously reveals his true personality is... unnerving, to say the least.
 * Blaz Blue: The main villain in once his identity is revealed.
 * Several of the villains in Final Fantasy Tactics 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.
 * Mimi from Super Paper Mario is a shapeshifter, but usually just looks like a cute green-skinned girl with pigtails and an Unlimited Wardrobe. That is, until you actually fight her and she transforms into a monstrosity akin to The Thing.
 * In the latest World of Warcraft expansion, the Worgen shift into animalistic form whenever they enter combat, including a permanent scowl.
 * Scarfy in the Kirby games is a cute little flying critter that changes into a furious, one-eyed Action Bomb.
 * , the killer in the last case from Phoenix Wright Ace Attorney: Justice For All, looks nice enough... but when he drops the act, he flips his hair, revealing the scars over his left eye, and his expression becomes a perpetual sneer.

Visual Novels

 * Members of the Berserker class in Fate Stay Night have a Game Face applied as part of their Mad Enhancement. Case in point: fourth Grail War Berserker (spoilers).

Web Comics

 * Looking for Group: "And Maikos?...This is no time for masks."
 * Goblins: The titular goblins, like many above examples, have eyes that go solid black when their game faces come on.
 * Heroic example from Misfile, when it's time to do the hero stuff the angels break out their Halos and Wings.
 * Hanna Is Not a Boys Name: Casimiro turns into some kind of bleach-white skeletal bat-person thing when he's threatening Hanna, which may be on purpose to intimidate him or just because the guy's a Mood Swinger.
 * In Gunnerkrigg Court, 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 Sluggy Freelance 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.

Web Original

 * Whateley Universe: Like Leland Gaunt, Carmilla only looks human. She's a budding Cosmic Horror. 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-haminess, and people left it alone. There were some good ones, though, and they were ususally screen caps of a Game Face. Others just were.

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 intimidatory purposes. Seeing a guinea pig fluff up to look intimidating is probably nature's Crowning Moment of Funny.
 * 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.
 * An excellent juxtaposition between Game Face (predation front) and play face (social front) can be seen 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 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. Which makes them just as tall as the car's bumper.
