-->-- ''Film/TheNeverEndingStory''

This is a trope for all the times a character's reflection in a mirror is different from what others (viewer included) see with the naked eye. In fiction, mirrors are treated as able to cause GlamourFailure in supernatural creatures, reveal MindControl, and if the [[MagicMirror mirror is magical]], reveal a character's true nature. The most common uses are revealing the [[ThisWasHisTrueForm true form]] of a {{Shapeshift|ing}}er or [[TheSoulless soulless]], and if a character is under MindControl.

In the first case, the mirror is acting the same way for the viewer as for the characters. We're being shown the monster's true form. In Mind Control cases (specifically the FreakyFriday, SharingABody, DemonicPossession and SplitPersonality) we're being shown what the characters are seeing that we aren't. The mirror shows the physical body of the character, while the camera shows the character controlling the body. The characters in the show will see the mirror image, i.e. the controlled person all the time. Directors can use this to create a sense of tension by showing only the viewer a monster's reflection, and keeping the other characters in the dark.

Another common variation is for the mirror to show an aspect of a person's personality. The nasty, spiteful, cruel, but beautiful girl becomes a hag in the magic mirror. Conversely, it can reveal the ReluctantMonster or [[BalefulPolymorph balefully polymorphed]] character to be noble and good.

A subtrope of MagicMirror, GlamourFailure and LieToTheBeholder. Compare TheShadowKnows. Contrast MissingReflection, where the mirror shows nothing at all.



[[folder:Anime & Manga]]
* ''Anime/ReadOrDie'': The Mirror Man, an agent of the British Library, has the ability to appear as someone else, but a mirror reveals his true form.
* Daisuke Niiwa from ''Manga/DNAngel'' can see [[PhantomThief Dark Mousy]] in his mirror reflection either standing beside him or in the corner of the reflection. They regularly have conversations this way. [[spoiler:In one of the late chapters of the manga, a magical mirror enables Dark's reflection to be seen by other people]].
* In the ''Manga/DragonHalf'' manga, Rufa is given a magic mirror that reveals her true nature. She quickly breaks it accidentally-on-purpose.
* The [[MonsteroftheWeek Jyarei Monsters]] in ''Anime/EtoRangers'' are revealed by Bakumaru's Revealing Mirror. The mirror does not show the monsters' reflections, however; the mirror works by shining a brilliant light forward in a wide area, and if a monster looks at the light, it reveals its true form.
* ''Manga/RosarioToVampire'': The Lilith Mirror does this, and even reverts the viewer back into his/her/its original form. Though in Moka's case, [[spoiler:the Rosario still affects Inner Moka and keeps her powers locked up]].
* ''Anime/{{Ulysses 31}}'' has the main characters encounter a Sphinx who is in possession of a mirror showing the true personality of people reflected in it. He keeps his SpoiledBrat of a daughter away from it.
* In ''Manga/DeathNote'', as Light Yagami is walking through a hall of mirrors supposedly mourning [[spoiler:L, who he was responsible for killing]], his reflection shows him smirking evilly with glowing red eyes, indicating his inner glee at [[spoiler: L's death]]. This doesn't actually seem to have anything supernatural behind it, but is a good way of showing Light's inner Kira while he is acting the part of mourner/friend/son whatever.
* In ''Manga/TheWorldGodOnlyKnows'', having an independent reflection who can talk is the first revealing stage of possession [[spoiler: by a goddess]].
* In ''Manga/{{Inuyasha}}'', Sesshomaru uses a youkai known as The Nothing Woman (Unmother in the English translation) to trick Inuyasha into thinking he's kidnapped his mother's spirit. It works, but Kagome notices in the nearby lake's reflection that she doesn't have a face.
* In the prologue of ''LightNovel/{{Vamp}}'', a shape-shifter's reflection in a window is used to deduce his true form.
* In ''Manga/CodenameSailorV'', among Sailor V's arsenal of weapons is an enchanted compact mirror designed to reflect people's true forms which helps her see through the disguises of antagonists and youma.

* ''LightNovel/HybridXHeartMagiasAcademyAtaraxia'': Aine has a strange dream where she's wearing nothing but a tiara and [[VaporWear a completely transparent dress]], but her reflection depicts her in her combat suit.
* ''LightNovel/FateApocrypha'': During the OP, when Ruler is in her civilian outfit, her reflection is in her armor. This doesn't happen in the actual anime.
* The cover page for the first chapter of ''[[Manga/MissKobayashisDragonMaid Miss Kobayashi's Dragon Maid: Kanna's Daily Life]]'' has Kanna's dragon form reflected in a puddle. This never happens in the series proper.

* René Magritte. Make of it whatever it may be. [[https://4.bp.blogspot.com/-z-5Xs1QUG8U/USEM65d_MRI/AAAAAAAABxk/pH8skdYruJc/s1600/Rene+Magritte+Ed.jpg It's]] [[TrueArtIsIncomprehensible incomprehensible]].

[[folder:Comic Books]]
* The way ComicBook/TheHood found out the source of his powers was [[DimensionLord Dread Dormammu]] was when the demon suddenly replaced his reflection in the mirror. Later Dormammu's preferred way of communication with Parker was to replace half of his reflection in the mirror, as a metaphor of their connection.
* When he first showed up, [[BigBad Dodge]] from ''ComicBook/LockeAndKey'' showed up as a corpse in mirrors. This doesn't seem to be a problem once he's out of the well, though.
* In a ''Magazine/DisneyAdventures'' comic of ''WesternAnimation/{{TaleSpin}}'', the heroes discover a mirror that apparently reveals their souls. Readers do not get to see this, which may be just as well when [[BigBad Don Karnage]] [[NothingIsScarier peeks at it and freaks out]].
* On the cover of ''Comicbook/TheLeagueOfExtraordinaryGentlemen'', Henry Jekyll's reflection is Edward Hyde.
* Inverted in ''[[ComicBook/{{Vibe}} Justice League of America's Vibe]]''. Vibe's powers also make him appear as a blur in any photographs or recordings of him, concealing his identity from cameras.
* Done in [[Recap/MyLittlePonyFriendshipIsMagicIDWAnnual2013 the 2013 annual]] of ''ComicBook/{{My Little Pony Friendship Is Magic|IDW}}''. Celestia took Sunset Shimmer to a magic mirror in hopes it would show her humility. But all Sunset sees a vague image of her becoming an alicorn [[spoiler:though if anyone saw ''[[WesternAnimation/MyLittlePonyEquestriaGirls Equestria Girls]]'', it was more then likely showing the darkness of her true self]] and just amplifies her desire over it.
* In the first volume of the comic book adaption of ''VisualNovel/SayaNoUta'', the last panel shows Saya and Josh (Fuminori) having sex in the mirror, showing that [[spoiler:Saya is not a human at all, but some sort of multi-limbed abomination.]]
* The ''Series/QuantumLeap'' version is used in the IDW ''Franchise/StarTrekExpandedUniverse'' story "Connections" when characters from ''Film/StarTrek2009'' start bodyswapping with their ''Series/StarTrekTheOriginalSeries'' counterparts. We see Chris-Pine-in-William-Shatner's-body as Pine, the reflection shows the Shat.
* ''ComicBook/CaballisticsInc'': The demon possessing Miss Simmons is visible in a reflection.

[[folder:Films -- Animated]]
* ''Disney/TheLittleMermaid'': Scuttle discovers that Vanessa, the woman Prince Eric is going to marry, is really Ursula when he sees her look into a mirror and the reflection is Ursula's.
-->'''Scuttle''': ''[[OhCrap The Sea Witch!]]'' Oh no! She's gonna...I gotta... [''flies into window!''] '''''ARIEL!!!'''''
* In ''WesternAnimation/MyLittlePonyEquestriaGirls'', Twilight Sparkle briefly imagines a mirror shows her pony form instead of her human one.
* In the ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'' short "My Past Is Not Today", Sunset Shimmer's reflection is of her demon self, but then she changes it back with a wave of her hand.
* In ''WesternAnimation/MyLittlePonyEquestriaGirlsLegendOfEverfree'', the human Twilight Sparkle keeps seeing her reflection change to [[SuperPoweredEvilSide Midnight Sparkle]].
* In ''Animation/TheSnowQueen2012'', Gerda and Kai's father made mirrors like this, and Gerda herself carries one. This is why the Snow Queen is afraid of mirrors; she can't bear to know what she has become.

[[folder:Films -- Live-Action]]
* In ''Film/AllOfMe'', Steve Martin's character sees Lily Tomlin's character, with whom he is SharingABody, any time he looks into a reflective surface.
* ''Film/{{Inception}}'':
** Within a dream, Eames[[note]]and probably anyone else, but Eames is the only that does so[[/note]] can copy other people's appearances. When he looked at himself in several mirrors, some reflections showed his true face, others reflected his disguise, and which mirrors did which changed (almost certainly deliberately) between cuts.
** Supposedly, when Ariadne did the double-mirror thing in her test dreams, only Cobb's reflection appeared.
*** When Ariadne is setting up the double-mirror, both her reflection and Cobb's appear, but once the infinite reflection is set up, the scene is shot such that Ariadne's reflections beyond the first are hidden behind Cobb's.
** This is actually ''Truth In Television'', according to lucid dreamers. One of the distinguishing features of lucid dreams is that inside them, mirrors don't work 'correctly' (i.e., they don't reflect, or reflect something else, or are distorted).
* ''Film/{{Sleepwalkers}}'': Despite having human forms, the cat creatures' true forms are shown if they're in view of a mirror.
* ''Film/SourceCode'': The viewer see Coulter running around trying to save the day, the reflection in the window and presumably everyone on the train sees Sean Fentress.
* Used at the very end of 2011's ''Film/{{Thor}}'' to show that [[spoiler: Dr. Selvig is being controlled by Loki]].
* ''Film/TheTenthKingdom'' used an inversion. The Queen used a hypnotic mirror which showed her merely standing behind Virginia, when in fact she was strangling her. It wasn't until Virginia glanced to the side and saw the truth in another mirror that she was able to break free.
* Subverted in a Richard Creena movie where he's playing a cop who brings the female suspect a large rectangular-wrapped parcel which he says is her 'true self'. She just laughs and says he's obviously got a mirror. He removes the wrapping and she's shocked to see a rather uncomplimentary painting of her by a former friend.
* In ''Film/JasonGoesToHellTheFinalFriday'', Jason's true hockey-masked self shows in reflective surfaces when he is possessing someone else. Cue a QuizzicalTilt when he finds this out himself.
* In ''Film/TheLeagueOfExtraordinaryGentlemen'', Jekyll talks to Hyde, whom he alone can see looking back at him from a mirror.
** It later shows the inverse when Hyde saves the Nautilus; Jekyll congratulates Hyde from the mirror.
* In ''Film/SamsonVsTheVampireWomen'', lady vampires actually cast reflections, but the mirror shows them as ancient crones with a bad skin condition.
* ''Film/{{Haunter}}'': When Lisa possesses Olivia's body in the world of the living, the mirror shows her actual face, but only to herself and the audience.
* In ''Film/TheLastWitchHunter'', when Chloe looks into mirrors the models at Danique's place are preparing themselves in, she notes that all the "supermodels" look like old crones.
* ''Film/{{Hypocrites}}'' is about a supernatural being called "The Naked Truth" (played by [[NudityEqualsHonesty a nude actress]]) who shows the hypocrisies of the local townspeople with a MagicMirror. A politician who campaigns on "honesty" is shown accepting bribes. A man and woman getting engaged are shown to be a cheater and a Gold Digger, respectively. The young people at the beach recoil in horror at the sight of the Naked Truth, but her mirror reveals them partying at the beach in skimpy (for 1915) bathing suits. The woman who followed the pastor up the mountain is revealed by the mirror to be in love with him.
* ''Film/BeautyAndTheBeast1946'': The magic mirror shows, when Belle's sisters look into it, an ugly old lady and a monkey respectively. Furthermore, Belle's beautiful necklace turns into a hideous rope when in their hands, reflecting the ugliness of their hearts once again.

* In ''Literature/FightingFantasy'', the true nature of [[PlantPeople mandrakes]] shapeshifters that pose as people can only be revealed with a mirror.

* In ''Literature/TheCastleInTheAttic'', one of the primary weapons of the [[EvilSorcerer evil wizard]] [[BigBad Alastor]] is a MagicMirror with this power. It eventually [[HoistByHisOwnPetard gets turned around on the villain himself]], with fairly satisfying results. When turned on TheHero, all he sees in the mirror is himself.
* ''Literature/HarryPotterAndThePhilosophersStone'': Played with. The mirror of [[SdrawkcabName Erised ]] shows the viewer's fondest desire ''at that moment'' and definitely NOT anything objectively ''true''.
* Used by NathanielHawthorne in at least two short stories, ''Dr. Heidigger's Experiment'' and ''Feathertop.'' In the former, a number of rejuvenated old people are seen in their wrinkly true selves in the mirror; in the latter, a handsome young cavalier is seen in the mirror in his true form of a dilapidated scarecrow.
* This is PlayedWith in ''Literature/BrothersInArms'': Miles is on a subway transport, and sees his reflection in the glass. He's currently wearing his mercenary uniform, but the Miles in the mirror has on his [=ImpSec=] uniform, reflecting his inner turmoil about his split personalities diverging. [[spoiler:Turns out it ''wasn't'' Miles -- it was his clone, and they were going to attempt a switch; they just had the wrong uniform.]] Miles passes it off as being a hallucination while on heavy medication.
* Subverted in ''Literature/{{Discworld}}'': Witches are well aware that mirrors ''don't'' show your true self. They can show your opposite a billion times, which can be problematic when there's only one soul to go around. Instead, on Discworld it is your ''eyes'' that reveal your true self, and no amount of magic or power can disguise eyes as part of a broader transformation.
* In Creator/LFrankBaum's ''Literature/QueenZixiOfIx'', the title queen can only make herself look beautiful to others because of this trope.
* In Creator/MercedesLackey's ''Literature/TheBlackSwan'' (a retelling of ''Theatre/SwanLake''), the sorceress Odile tells Odette that Baron von Rothbart won't have any mirrors in his house because "mirrors show the truth." When he asks Queen Clothilde to cover or hide all the mirrors in her ballroom, you know something's up.
* ''Literature/TheNeverendingStory''. Played with; Bastian and Atreyu aren't the same person, but they do see each other in the magic mirror and Atreyu is in many ways Bastian's Avatar inside Fantastica. Atreyu is merely confused by it, but when Bastian reads it he ''freaks the hell out''.
* In the ''Literature/{{Spellsinger}}'' novel "Time of the Transference," the group finds this kind of mirror. Mudge is shown as an old otter whose body and mind have succumbed to hedonistic excesses, to the alarm of everyone else, but he says that he doesn't mind because he already saw himself that way (and he is in the process of changing his lifestyle due to Weegee's influence). Weegee appears as a regal princess. Cautious simply appears as himself. Jon-Tom has no reflection at all because of his indecision over who he is (spellsinger, law student, rock musician) and where he belongs (in his old world or in the world with the others).
-->'''Cautious:''' I am what you see. Worse things to be.
* In ''Literature/{{Pact}}'', the protagonist Blake Thorburn lacks a reflection of his own--in its place is Rose Thorburn, his magically-generated DistaffCounterpart, who is trapped in a mirror world, only able to go where there are corresponding reflections in Blake's world. Rose is not just Blake born as a girl, but an Other created by their grandmother--when Blake dies, his death will allow Rose to step into the real world in his place, taking the mantle of heir to the Thorburn family and all the enemies that come with it.
* In Barry Hughart's ''[[Literature/BridgeOfBirds The Story of the Stone]]'', The Mirror of Souls is a large crystal mirror in the Chinese underworld that can see and show all of your past incarnations. It can speak and display scenes from the past and a spirit level that shows how good or evil you were.
* The Creator/AlanDeanFoster series ''Literature/JourneysOfTheCatechist'' features the main character, Ehomba, using a mirror to scare away some creatures that had been bombarding the party with giant pine cones. Afterward, each character looks into the mirror in turn. The normally jovial and exuberant Simna appears much more somber and depressed. The enormous cat Ahlitah appears as the height of feline majesty, and the recovering drunkard Knucker sees himself as he is when drinking. When Ehomba first looks into the mirror, the other three are momentarily blinded by the sun's reflection when they try to look. Looking again, the mirror is showing Ehomba exactly as he is. [[spoiler:Only Ahlitah notices that the sun was in front of Ehomba, not behind him, and so couldn't have been the source of the light that the others saw in the mirror.]]
* In chapter eight of ''Broken Gate'', this is inverted, as the mirror doesn't really show Nezumi's true self, actually, as Nezumi's reflection is the opposite of what she is, right down to being more emotive. The reason for this because said reflection is a manifestation of her madness, the which she talks to.
* In ''Literature/TheMachineriesOfEmpire'', any mirror Cheris looks at shows her Shuos Jedao, who's attached to her soul, instead of her own reflecton.
* In the teen horror novel "Mirror, Mirror" (a reimagining of ''Literature/ThePictureOfDorianGray''), the beautiful AlphaBitch protagonist receives a mirror as a gift from a mysterious new friend. As her personality gets more and more ruthless and nasty, her reflection in this mirror gets increasingly horrific. She also becomes increasingly unbalanced, as she will react with fright, look into another mirror in which she looks normal, then look back into the jinxed mirror, where she also now looks normal, leading her to wonder if she's hallucinating and going crazy.
* Invoked in ''Literature/TheChroniclesOfPrydain.'' [[TheHero Taran]] spends most of Book 4 searching for a MagicMirror that supposedly shows the true nature of anyone who looks in it. Eventually, he reaches it, and discovers that [[spoiler: it's a puddle of water]]. He looks in it and [[spoiler: having gone through a lot of CharacterDevelopment,]] sees himself for who he is-a person with some faults, and some flaws, but overall good and kind. Above all, he is who he has always been-himself, no more, no less. [[MaybeMagicMaybeMundane It's never revealed whether the mirror was actually magic,]] or whether it was never anything more than [[spoiler: a pretty puddle of water]].

[[folder:Live-Action TV]]
* In the ''Series/{{Smallville}}'' episode "Tomb", Chloe is possessed by a vengeful ghost. Her reflection becomes that of the ghost.
* ''Series/ThirtyRock'':
** The show had an HD camera in one episode which shows the real you. Liz Lemon shows up as an old hag, Pete shows up as an old man, Kenneth the page shows up as a Muppet, and Jack Donaghy looks 20 years younger.
** Kenneth once mentioned that he sees only a white haze when he looks into a mirror.
* ''Series/QuantumLeap'':
** Inverted. On-screen, Sam appears as himself. But mirrors and reflective surfaces show the true appearance of whomever he's leaped into. [[spoiler:This startles him in the series finale, when he sees himself in the mirror with gray hair]].
* ''Series/StargateUniverse'':
** Most common in the latest branch of the franchise, it's also been used elsewhere. Ancient tech allows two people to switch minds. The controller is the one whom we see. The controlled person is visible to the other characters, and in mirrors, TV feeds, photographs, ''etc''.
** That tech originated in ''Series/StargateSG1'', with Daniel and Vala looking into a mirror and discovering that they've been transported into other people's bodies.
* ''Series/TheXFiles'':
** The episode "Dreamland" is a FreakyFridayFlip in which Mulder switches places with [[TheMenInBlack Man In Black]] Morris Fletcher. As in the ''Series/QuantumLeap'' example, the audience continues to see Mulder as Mulder, but his reflection reveals that everyone else sees him as Fletcher, and ''vice versa''.
** In "Chimera", every mirror at the crime scenes was shattered so the killer would not see her true self. She suppressed [[SplitPersonality this side of her personality]] and [[TheKillerInMe honestly was not aware that she was responsible for the murders]].
** Edpisode "The Unnatural" is about an alien who falls in love with baseball, taking on the form of a Negro player in 1947 Roswell. At one stage while he's asleep another character sees his true [[TheGreys Grey alien face]] reflected in the window of the bus they're traveling on. The image disappears when he wakes up.
* ''Series/{{Best Friends Whenever}}'': When Cyd and Shelby travel to a specific time, their appearances (in their and the viewers' point of view) don't change. But when they look in the mirror (and in the way everyone else sees them), they are in the bodies of their past/future selves. A {{Running Gag}} is that they always take a selfie in every timeline they are in that shows what they look like then. Cue to them jumping to the 70s in which their appearance don't change even their selfies, due to the fact that they jumped to a timeline where they don't even exist.
* The true face of several monsters in ''Series/{{Supernatural}}'' that can pass for humans (like wraiths, changelings and sirens) are revealed by mirrors. In "Sam Interrupted", Dean is watching a mirror dome for a wraith he knows is in the building. However, the wraith has already infected him with a hallucinogen, so Dean ends up attacking the wrong man.
* An episode of ''Series/StarTrekTheNextGeneration'' starts with [=LaForge=] walking around. He then looks at a reflective surface, and we are shown a cylinder hovering in the reflection instead of the engineer. It turns out Geordi was using a telepresence system to move as if he was the drone. In this case, the mirror reveal is for the audience.
* ''Series/TwinPeaks'' has two scenes where BOB showed up in the reflection of the person [[DemonicPossession he was possessing]]. Said mirrors tend to be [[RageAgainstTheReflection damaged]]. In ''[[{{Revival}} The Return]]'', it turns out BOB [[spoiler:was not controlling Cooper's body, just passively inhabiting the body of Cooper's EvilTwin]], but a look in the mirror briefly shows a fragment of his real face, confirming BOB is still there after all those years.
* Played with in ''Series/KamenRiderDragonKnight.'' [[BigBad General Xaviax]] approaches potential Riders disguised as a human, but when he glances at his reflection, his true form is revealed.
* The Latinoamerican {{Telenovela}} ''La Mujer En El Espejo'' (''The Woman in the Mirror'') has an interesting variation: a magic mirror that "contains" the image of a beautiful woman. It can be used by women to take on her looks, but regular mirrors will still reflect their true appearance.
* ''Series/AreYouAfraidOfTheDark'':
** The episode "The Tale of the Mystical Mirror", the antagonist is an old witch/beauty shop owner who uses illusions to maintain the appearance of youth, but mirrors reveal her true age. When the protagonist investigates the witch's house after her friends who work at the shop go missing, she realizes something is wrong when she can't find any mirrors in the house. Clearly taken from the folklore surrounding Transylvanian (Romanian) Countess Erzebet (Elizabeth) Bathory.
** In "The Tale of the Captured Souls", Peter avoids mirrors or getting his picture taken by a camera. [[spoiler:Danny (the heroine) soon finds out through the mirror monitors in his secret laboratory that he is [[ReallySevenHundredYearsOld really 100 years old]] and that he has killed off visitors by RapidAging using the [[FountainOfYouth laboratory's]] VampiricDraining mechanism.]] Partly inspired by Creator/OscarWilde's ''Literature/ThePictureOfDorianGray'', or possibly by the concept that pictures steal bits of the soul.
* In ''Series/DeadLikeMe'', similar to Quantum Leap, the camera sees the main characters (who are all grim reapers who died in an accident or a murder) as they were in life; mirrors show how they look to the other characters. This change in appearance is to keep anyone who knew them in life from catching on.
* ''Series/BabylonFive'': As John Sheridan prepares to leave for Z'ha'dum, there's an odd scene where he recalls in flashback [[SpiritAdvisor (or is it a flashback?)]] the words of Kosh, who warned him against going. As the words are heard again, Kosh appears in the mirror over Sheridan's shoulder. Of course, had already been established that Sheriden had been TouchedByVorlons.
* ''Series/DoctorWho'':
** In the serial "The Power of the Daleks", Patrick Troughton's Doctor looks into a mirror and sees William Hartnell; a reassurance to an audience who've never seen a regeneration before that he is the same man.
** The Doctor also has a mirror that can identify various species, a gift from his godmother that has been sitting in the TARDIS junk-drawer for over a millennium. He quickly tests it on himself to see if it still works, leading it to bring up the First and Second Doctor before he puts it down satisfied with this field-test.
** At the end of "Amy's Choice", [[spoiler: the Doctor sees the Dream Lord, really the Doctor's dark side]] reflected in the glass of the TARDIS console.
* In the series premiere of ''Series/{{Merlin 2008}}'', Mary Collins' true form (evil old hag) is revealed in mirrors. It later shown to happen with every magical disguise. The reflection shows the true form. Though for some reason very rarely characters are exposed via reflection. Usually it is only shown to clue the ''viewers'' in.
* On ''Series/MythQuest'', whenever Alex or Cleo go into a myth they see themselves and each other as they are, but the rest of the world and anything reflective show them as the characters within the myth that they replace.
* In the ''Series/HerculesTheLegendaryJourneys'' episode "Protean Challenge", the shape-shifter Proteus is revealed in mirrors.
* ''{{Series/Salem}}'': Mary's reflection is that of an old hag, one she claims represents the state of her soul.
* The episode "Mirror of Truth" has this in ''Series/BeyondBeliefFactOrFiction''. A vain woman goes to a make-up specialist, only to find the job done not to her expectations, insulting the owner and leaving without paying. The owner swiftly curses her to look as ugly as she is inside. Soon, her fiance calls off the marriage, she tries to fix her face with creams and finally asks a professional surgeon for plastic surgery. The viewer never once sees her face ever since she left the shop, leading to wild expectations about how she looks. [[spoiler: She still is very beautiful, but when she looks in the mirror, she sees a disgustingly disfigured face staring back at her]].
* Played with in ''Series/{{Lucifer}}'' where a GlamourFailure is often shown via a reflective surface, but doesn't happen every time there's a mirror.
* In the renewal series of ''Series/{{The Outer Limits|1995}}'' episode "First Anniversary," aliens stranded on Earth are able to fool the senses of the men they marry into thinking that they are beautiful human women, changing outward appearances each time. After a year, the glamour power wears off as the humans become acclimated, able to see through any form. As one of the victims started to sense something was wrong, he was able to see his wife's true form for a second in the mirror of their bathroom.
* ''Series/{{Charmed}}'' plays this straight or inverts it on several occasions:
** When a human is possessed by an alchemic life essence, the guest sees, and can speak to, the host's trapped soul on mirrors and other reflective surfaces; others see a normal reflection. This happens to a business man and, later, Piper.
** When a Cupid projects Paige into [[spoiler: her husband]] Henry's mind, Henry sees Paige in the mirror.
** [[InvertedTrope Inverted]] when the sisters fake their death, they cast a glamour spell that makes them look as different people to anyone "but not those we call family". They (and the audience) see each other as their true selves, while all mirrors show the glamour.
* ''Series/OnceUponATime'': When a young ogre is captured in the forest, Belle wants to be certain he's evil before taking drastic measures. While she goes to fetch a magic mirror that reveals the monster within, Gaston attacks the ogre while faking self-defence. The magic mirror reveals Gaston's true evil nature when his reflection, not the ogre's, show a red glow in his eyes.
* In the ''Series/Warehouse13'' episode "Fractures", Artie notices Alice Liddell's reflection in a serving tray carried by a hotel waitress. He and the other Warehouse agents realize they can use reflective surfaces to track Alice as she [[GrandTheftMe body jumps]] from one hotel guest to another.

* ''Music/{{Quadrophenia}}'': The album cover has each of the mirrors on Jimmy's scooter showing a different face (one of each member of The Who, each representing one of his personalities).
* ''Mirror of Souls'' by Christian progressive-power metal band Theocracy zig-zags this. The protagonist goes through a hall of mirrors that create flattering reflections of his good qualities. Later he encounters the titular Mirror of Souls, the very eyes of God, which reveals his true nature: a corpse ravaged by sin. After he pleads for salvation, the Mirror reflects Christ in his place.

[[folder:Mythology and Folklore]]
* According to Japanese mythology, this is usually how you can figure out if someone you know is a {{Kitsune}} as while they look normal to you, a mirror shows what they really are. However, according to some, the mirror has to be an old one.
* Likewise, the same works for vampires, that is, because, they don't have souls, they don't have reflections, unless the mirror doesn't have a silver backing.

* ''[[Pinball/TheWhosTommy The Who's Tommy]]'' shows the adult Tommy looking into a mirror, and seeing his innocent childhood self reflected inside.
* The backglass for Creator/DataEastPinball's ''Pinball/TalesFromTheCrypt'' shows a woman standing before a mirror, where the reflection reveals her to be a zombie.

* ''TabletopGame/DungeonsAndDragons'':
** Magazine/{{Dragon}} Magazine #50 had the magical artifact Barlithian's Mirror. Anyone who looked into it saw his or her true self, regardless of any illusions, creature powers (such as a vampire's invisibility to mirrors) or shapechanged form. In addition, a lycanthrope would see its alter ego (''e.g.'', a werewolf in wolf form would see a human and one in human form would see a wolf).
** The supplement ''Open Grave'' uses this trope in one picture - a beautiful noblewoman's reflection reveals her true form as a lich.
** The TabletopGame/{{Ravenloft}} character Gabrielle Aderre appears to be in her mid-twenties, but she sees her true age (mid-fifties) in mirrors. Despite still being [[GrandmaWhatMassiveHotnessYouHave very attractive]], she considers her true appearance hideous.
* In ''TabletopGame/MagicTheGathering'', silver dispels the glamour of Innistrad's vampires. This means that mirrors (silvered glass) show vampires as they were when they were still human. Since Innistrad vampires regard themselves as a MasterRace, this is supremely disturbing to them.
* ''TabletopGame/VampireTheMasquerade'':
** The Obfuscate Discipline (which either makes the user invisible or appear to be someone else) is generally ineffective against cameras or other mechanical sensors.
** The Lasombra either [[MissingReflection don't leave images on cameras and mirrors]], or they have a weird abnormality which means their reflection is that of what they would really look like if they weren't turned into vampires: usually a rotting corpse or a walking skeleton.

* Inverted in one of the possible quests in the video/PC game ''VideoGame/{{Darkstone}}''. A witch has cursed the women of a local village to turn to stone if they ever become more beautiful than she is. Since she looks to be about three million years old, all the women are statuary. Your character must visit the local dungeon and find a perfectly normal-looking man who is convinced that he's ugly as sin, so has come down to find the Fountain of Youth in order to hopefully fix the problem. Turns out that his real problem is that he's been using something called the Mirror of Lies, which makes beautiful people appear ugly and vice-versa. After getting it from him in exchange for a normal mirror, your character gives the Mirror of Lies to the witch, fooling her into believing that she's young and gorgeous again, so she releases the spell on the village.
* ''VideoGame/DragonQuest'' games:
** The Mirror of Ra appears in several games. Whenever it appears, it's always used to reveal something's true form.
** In ''VideoGame/DragonQuestII'', it's used to break a BalefulPolymorph by revealing that [[spoiler: the dog who follows you around in one village is actually the cursed Princess of Moonbrooke]].
** In ''VideoGame/DragonQuestIII'', it reveals the true identity of the Orochi and exposes a FakeKing plot.
** In ''VideoGame/DragonQuestV'', it's used to SpotTheImposter after [[spoiler: the [[UnwittingPawn Queen Dowager]] confronts her doppelganger]].
** In ''VideoGame/DragonQuestVI'', Ashlynn seeks the Mirror of Ra because she hopes [[spoiler: it can break whatever's causing her invisibility]]. Unlike other examples in the series, this ''doesn't'' immediately cause the mirror to break, because it's later used [[spoiler: against the evil dream king to reveal his true identity, and the real evil king to prevent him from launching you into the dream world again.]]
* A [[GoodBadBug glitch]] causes this to happen in ''VideoGame/JakIIRenegade''. When looking in the mirror behind the bar in the Hip Hog Heaven Saloon, Jak's reflection has the horns of his [[SuperpoweredEvilSide dark form]]. They flicker in and out as he moves.
* In ''VideoGame/KingsQuestVIHeirTodayGoneTomorrow'', there is a mirror with this quality; depending on which path you take, it can be used in one of two different ways. The basic good ending has Alexander using it to SpotTheImposter by forcing a genie to resume his true form. The best ending has him use it against Death himself, forcing him to witness the horror of his own existence, causing him to shed a single tear and lose his wager against Alexander.
** ''VideoGame/KingsQuest2015'' Chapter 3 introduces a magic canvas that functions the same way. King Graham, for example, is still the fresh-faced young man he was back in Chapter 1, while Hagatha is revealed to be [[spoiler:a beautiful princess]]. It comes back in Chapter 4, where it reveals that the Sphinx is [[spoiler:Manannan]].
* At one point in ''VideoGame/LunarTheSilverStar'', your party comes across an item called Althena's Mirror, and uses it soon afterward to expose Xenobia, who had been posing as [[spoiler:Lemia, head of the Vane Magic Guild (the real one was captured and imprisoned)]].
* In ''VideoGame/{{Persona 3}}'', you have to break the mirrors that ''don't'' show your reflection in order to get to the Lovers boss chamber.
* In ''VideoGame/QuestForGloryII'', the Enchantress Aziza uses water magic to reflect the true image of the Hero of Spielburg's pack animal, to reveal that it is actually the missing Emir of Raseir.
* In ''VideoGame/RuleOfRose'' a bathroom mirror on the Airship shows, not the protagonist's "true" form, but the environment's; it shows the orphanage that is the Airship's true face.
* In ''VideoGame/ShinMegamiTenseiIIINocturne'', you have to find Mot before you can engage in his battle. He disguises himself as a statue and hides among the other statues. The trick to finding him is that the floor that the statues are on is a reflective surface. Mot is the statue that isn't reflected in the floor.
* ...and in ''VideoGame/ShinMegamiTenseiStrangeJourney'', you have to use a magical mirror to unmask Amaterasu, break her out of the illusion she's trapped in, and allow her to return home. (There's some GeniusBonus here for those familiar with Shinto mythology: A mirror was a key item in the Gods' ploy to draw Amaterasu out of the cave she was hiding in and get her to return to the heavens.)
* In ''VideoGame/TalesOfPhantasia'', any character possessed by Dhaos has a [[TheGrimReaper Grim Reaper]] figure floating above their mirror reflection. Early on, Cress exploits this when Rhea and Demitel confront each other to find out who is responsible for destroying Harmel village.
* ''VideoGame/BlazBlue'':
** The Ammit Cryas is a truth grimoire in the form of a mirror - its power is to show the true self of its current wielder, but if held too long the wielder may be drawn into it. Three characters are known to have held it. In order:
** Makoto was completely unaltered in the reflection of the mirror. Presumably, tumultuous origins notwithstanding, she has nothing to hide.
** Kajun Faycott, one of two ''Remix Heart'' characters, is reflected in a lab coat standing alongside Professor Kokonoe, denoting her allegiance to Sector Seven.
** Mai Natsume, the other ''Remix Heart'' character, is reflected as a male shadow - she loses her hold on the mirror before the full truth could be revealed.
** When Relius uses his Astral Heat on Terumi, we see a mirror standing behind him showing his true ghost form.
* In ''VideoGame/LollipopChainsaw'', Mariska possesses Rosalyn to lure Juliet and Nick into a trap. Mariska appears when "Rosalyn" is in front of their bus' rear-view mirror. This is only for the audience's benefit, because Juliet and Nick don't notice before Mariska gets the drop on them.
* There's a magic mirror in ''VideoGame/LufiaIIRiseOfTheSinistrals'' which shows the truth about anyone who looks into it. People use it to [[MundaneUtility find out if their spouses have been faithful to them]]. [[spoiler: When Iris looks into the mirror, she (and the player) sees her true form as Erim.]]
* ''VideoGame/FinalFantasyIV'' plays with this a bit. The player's character, Cecil [[spoiler: travels to Mt. Hobs in order to become a paladin. Upon reaching the summit, he enters a mirrored chamber where he is removed of his dark armor and becomes a paladin. However his reflection in the mirror does not change and he must defeat his Dark Knight self in battle as his trial... Or rather, let his Dark Knight self defeat himself through self-harming attacks]].
** This turns out to be a bad idea. [[spoiler:Rejecting a part of who you truly are, no matter how wrong it is and how well you seal it away, can result in some serious mental damage due to suppressing who you are. In the sequel, an alternate personality starts attacking people until Cecil comes to terms with the fact that he is both a Paladin AND a Dark Knight.]]
* During Nimdok's scenario in '' VideoGame/IHaveNoMouthAndIMustScream'', he comes across project PERFECT IMAGE, a Nazi project which shows you yourself with utter objectivity. Not only does it [[spoiler:show Nimdok the truth of his Jewish heritage]], but it's also implied to be [[spoiler:the true reason Hitler committed suicide.]]
* Though it's often forgotten about, Eiki Shiki from ''VideoGame/{{Touhou}}'' possesses a mirror that reflects the viewer's past deeds. She can also use it to pit the viewer against a copy of herself.
* In the second-to-last level of ''VideoGame/MonumentValley'', the main character walks past a mirror in which she is reflected as a white bird. [[spoiler:At the end of the last level, she transforms back into one as a reward for returning all the Sacred Geometries she stole.]]
* DummiedOut in ''VideoGame/{{Undertale}}''. There's a set of sprites for this, [[spoiler:showing the Fallen Child's reflection instead of Frisk's]], but the flag that causes this to occur can only be set through DebugMode, and even then only works in a single room. Presumably it was intended to be used [[spoiler:after completing a KillEmAll run and selling your SOUL]], but given that it was scrapped, it's impossible to say for certain.
* In ''VideoGame/MetalGearSolidVThePhantomPain'' [[spoiler:under the right lighting conditions, Venom Snake's reflection on the chopper window will flash the image of the character created at the start of the game, foreshadowing that Venom is not the real Big Boss but rather the Medic, whose previous appearance is said character]].
* In ''VideoGame/VampireTheMasqueradeRedemption'', vampires have normal reflections in mirrors, except for members of the Lasombra clan. Fittingly, the only member of that clan encountered in the game has a haven with wall-sized mirrors to play up that fact (as well as many painted portraits, the only way the Lasombra can still see their own faces).

[[folder:Visual Novels]]
* In ''VisualNovel/UminekoWhenTheyCry'', this is implied (and in the seventh arc stated) to be the reason why Beatrice is repelled by mirrors. [[spoiler:[[AmbiguousGender Sayo Yasuda]], Beatrice's true identity, hates mirrors because mirrors do not acknowledge their make-believe appearance and remind Sayo that they're not the powerful witch they pretend to be. Thus, in the story, the camera will always show which personality is being depicted. Sayo's actual image is never seen in the visual novel.]]
* In ''VisualNovel/ShallWeDateWizardessHeart'', the Persona Mirror is a MagicMirror enchanted to reflect a person's true self. When Elias looks into it, it reveals his insecurities and his frustration about having to live up to his family's legacy. When the protagonist looks into it, however, it shows that her outward self and her inner self are exactly the same.

[[folder:Web Comics]]
* In ''Webcomic/{{Daniel}}'', Daniel himself is a vampire that throws a fit if he gets a look at himself in a mirror, apparently seeing something grotesque and terrifying.
* In ''Webcomic/{{Sinfest}}'', [[http://www.sinfest.net/view.php?date=2012-04-01 Slick is sure that being BZOMF'ed didn't affect him, but we see the mirror at the end.]]
* ''Webcomic/YetAnotherFantasyGamerComic'' has The Mirror of True Reflection, which actually [[http://yafgc.net/comic/1550-true-reflections/ shows]] different aspects of the viewer's personality (resulting in several "true" reflections). This turns out to be merely the warning sign against [[DownTheRabbitHole entering the mirror]] to try to find the MacGuffin hidden within, as you have to fight off your inner demons given form to claim it. Fortunately, your inner virtues are there as well.
* In ''Webcomic/{{Godslave}}'', the window in Sobek's office reflects his divine form rather than human.

[[folder:Web Original]]
* Mirrors reveal that Sweet Synn, a supervillain from the ''Roleplay/GlobalGuardiansPBEMUniverse'' is actually a demonic succubus, regardless of the form she's currently wearing (and she usually looks like whatever you find most attractive in a woman).
* In the dream "True Identity" on the Website/NightmareProject, a mirror shows the dreamer a hideous demonic visage.
* One scene in ''WebAnimation/MysterySkullsAnimated: Ghost'' shows the trio pass by a set of mirrors. Vivi's reflection has no eyes, Arthur's doesn't show his ([[ArtificialLimbs prosthetic]]) left arm, and Mystery's mirror ''shatters''. [[spoiler: This actually serves as {{foreshadowing}} towards the backstory the group shares: Vivi suffered a HeroicBSOD (and quite possibly [[LaserGuidedAmnesia amnesia]]) after the death of her boyfriend and the group's fourth member, Arthur lost his arm to DemonicPossession and was the one who ''killed'' said boyfriend (unwillingly; again, DemonicPossession), and Mystery [[AnimalisticAbomination isn't a dog]].]]
* ''WebVideo/{{Petscop}}'': The Quitter character appears to be a reflection of the game protagonist, although at one point they aren't synced and the Quitter must regain their spot.

[[folder:Western Animation]]
* ''WesternAnimation/AladdinTheSeries'': Al has to find a mirror like this in a room full of magic mirrors which all show something different. He finds it when he notices that his reflection is wearing his "street rat" clothes instead of the princely robes he has on. Then Iago sets off the trap because he thinks the mirror which depicts himself covered in jewelery must be the one.
* ''WesternAnimation/JackieChanAdventures'' Season 2: whenever Shendu possesses someone, his host can see his face in the mirror.
* In the ''WesternAnimation/JusticeLeague'' episode "Paradise Lost", when Wonder Woman and Superman find an ancient artifact, they start seeing each other as monsters and fighting, thinking that the "monster" had done something to their friend. Superman is the first to catch on upon seeing Wonder Woman's reflection in a fountain, and stops fighting altogether, allowing Diana, still seeing him as the monster, to mercilessly pummel him. It's not until the "monster" points to a mirror that she looks and sees she was fighting Supes all along.
* In ''WesternAnimation/TheScarecrow'', Count Grisham ends up exposing Feathertop as a scarecrow while using mirrors in an attempt to force Feathertop to look at him.
* In an episode of ''WesternAnimation/ThePiratesOfDarkWater'' Bloth used a magical artifact to [[FreakyFridayFlip swap bodies with Ren]], as well as having Konk swap bodies with Niddler. However, while in the other person's body, their reflection still shows who they really are.
* In the "Baby Doll" Episode of ''WesternAnimation/BatmanTheAnimatedSeries'', the main antagonist suffers from a condition that kept her from aging. Despite being well over 30, she physically looks younger than a pre-teen. When the Dark Knight chases her into a house of mirrors, she stumbles across one that reflects what would look like under "normal" circumstances.
* In ''WesternAnimation/ThunderCats'', this is true of the shape-shifter Mumm-Ra.
* In the ''WesternAnimation/GravityFalls'' episode "Soos and the Real Girl", [[{{Yandere}} Giffany's]] avatar shows up on the screens of arcade games after she possesses an animatronic beaver.
* In the ''WesternAnimation/SamuraiJack'' episode "Jack and Swamp Monster", [[BigBad Aku]] disguises himself as a hermit so Jack can lead him to the gems and armour of Cronos which he will use to destroy Jack. As they're rafting down the river Aku looks into the water and sees his normal form reflected in the water, so he summons a [[MakesJustAsMuchSenseInContext giant hovering alligator]] as their transport so Jack won't see it. [[spoiler: It didn't matter anyway, because Aku's PaperThinDisguise never fooled Jack in the first place]].
* ''WesternAnimation/StevenUniverse'':
** In "Storm in the Room", Steven enters Rose's room and asks to see his mother, who appears. Eventually, he takes out his phone to take a picture of them together, but the screen shows him standing alone in a black void, reminding him that she (and everything else in the room) is simply a construct drawn from his own mind.
** In "Jungle Moon", Stevonnie camps out in a long-abandoned Diamond base and [[DreamingOfTimesGoneBy dreams of a scene that took place there when it was still in use]]. Stevonnie plays the role of [[spoiler:Pink Diamond]], which is revealed when they view their own reflection in a glass window.
* In "Brick Like Me" from ''WesternAnimation/TheSimpsons'', [[BuiltWithLEGO LEGO Homer]] starts seeing the real Homer in reflective surfaces after having a vision of his reality, where he was bonding with Lisa over LEGO construction sets. At one point, he yells at his reflection on the front window of the LEGO world's Kwik-E-Mart, causing him to be MistakenForRacist by [[AsianStoreOwner LEGO Apu]].
* ''WesternAnimation/PepperAnn'': In "My Mother, Myself", Pepper Ann and her mother experience a FreakyFridayFlip, and P.A.-as-Lydia sees a reflection of her normal self ([[TheManInTheMirrorTalksBack who talks to her very often, by the way]]).
