When you look into a mirror, you see a person who is in some ways identical to yourself, but who is also in some ways your opposite. If you are right-handed, your mirror will show a left-handed person, and vice versa.

This "same but opposite" is the cornerstone of a MirrorUniverse. A character's "same but opposite" counterpart is the Mirror Self. However, a MirrorSelf can sometimes also be created by misuse of AppliedPhlebotinum.

Not to be confused with an AlternateSelf, who is the same person without being an opposite. Might have gone through different experiences and been changed by them, but is not a polar opposite like the Mirror Self. Compare MesACrowd.

[[folder: Anime And Manga ]]

* Subverted in ''Manga/CardcaptorSakura'' by the use of The Mirror card which creates an exact copy of Sakura that she can then control. Before her capture The Mirror appeared to be a mischievous opposite version of Sakura but this is likely just the personality of the card itself and not because it's Sakura's reflection.

[[folder: Comic Books ]]

* In the ''[[TheSmurfs Smurfs]]'' story "The Hundredth Smurf", a Smurf's mirror is [[LightningCanDoAnything struck by lightning]], which brings his reflection to life. The reflection speaks backwards and does everything the original Smurf does, but in reverse (lifting the right arm when the other lifts the left, for instance). After he causes chaos in the village by his opposite nature, the reflection decides to return to the mirror, but he goes through it instead, and comes out a regular Smurf.
* John Byrne retold [[WonderGirl Donna Troy]]'s origin in ''Franchise/WonderWoman'' so that she was originally the mirror self of Princess Diana as a teenager, but given a separate personality by the sorceress who owned the mirror. Donna Troy was then captured by Queen Hippolyta's nemesis Dark Angel, who mistook her for Diana, and subjected her to live multiple lives that all ended in tragedy, ultimately leading to the one where Donna becomes Wonder Girl/Troia of the ComicBook/TeenTitans. This origin has recently been retconned out of her history since 2006.

[[folder: Fanfiction ]]

* In ''Fanfic/EmpathTheLuckiestSmurf'', Vanity's Mirror Self goes by the name of [[MeaningfulName Century]], but in "Vanity's Double" shows that he isn't afraid of swords or swordfighting, which proves helpful when is cast alongside Vanity in the role of Robin Smurf.

[[folder: Film ]]

* ''ScottPilgrimVsTheWorld'' has "Nega-Scott". [[spoiler: Subverted. Other than his [[Franchise/TheLegendOfZelda Dark Link appearance]] he's exactly like Scott and they get along swimmingly.]]
* In ''Film/TheDarkCrystal'', the "good" urRu/Mystics and the "evil" Skeksis are split beings, formed from a race (the "urSkeks") not native to the world of the film, and who were formed when the Crystal itself was split. Each Mystic has a Skeksis counterpart, and if one dies, so does the counterpart.

[[folder: Literature ]]

* The ''Literature/CallahansCrosstimeSaloon ''story "Mirror/rorriM Off The Wall" has a MirrorUniverse where everything is in reverse/backwards, including handedness and fingerprints. One of its inhabitants is a MirrorSelf of someone in our universe: they're both named Robert Trebor.

[[folder: Live Action TV ]]

* In the ''Franchise/StarTrek'' universe, there is a MirrorUniverse where every character has a MirrorSelf. Good characters generally have evil Mirror Selves, and vice versa (there are exceptions, like [[Series/StarTrekDeepSpaceNine "Smiley" O'Brien]]). Ambiguous characters often have their defining traits reversed.
* The Doctor encounters mirror counterparts of the UNIT team in the ''Series/DoctorWho'' serial "Inferno".
** It's {{Fan Wank}}ed that the mirror universe Doctor himself is [[BigBrother Fearless Leader]] of the mirror world.
* In ''Series/{{Charmed}}'', the MirrorWorld has a MirrorSelf of every character, just like in Franchise/StarTrek. The characters also have alignment-shifted powers, creating oxymorons like the Demon of Hope.
** It's not really an oxymoron, because demons are the good guys there.
** It's not impossible for [[HopeSpot hope to become figuratively demonic]].

[[folder: Newspaper Comics ]]

* In ''ComicStrip/CalvinAndHobbes'', one story arc features Calvin making a MirrorSelf of himself. The real Calvin doesn't want to do his homework or clean his room, but his MirrorSelf is a well adjusted polite little boy who gladly does these things... and proceeds to destroy his life [[GoneHorriblyRight by being way too nice.]]

[[/folder]]

[[folder: Tabletop Games ]]

* Using the right spells in ''TabletopGame/DungeonsAndDragons'' allows characters to enter the Plane of Mirrors, a transitive plane that uses a set of mirrors as a PortalNetwork - the catch was that entering it created an opposite-alignment mirror counterpart (opposite primary hand and all) that would try to kill you and take your place in the "real" world. An adventuring party that pursued a foe onto the plane ran the risk of encountering its very own band of PsychoRangers... as well as one potential ally.

[[folder: Video Games ]]

* Close to the end of ''VideoGame/QuestForGloryIII''. Each hero was forced to fight a twisted mirror image of him- or herself.
* The final boss of the Old Kingdom instance in ''VideoGame/WorldOfWarcraft'' summon mirror versions of the heroes for them to fight.
* In ''VideoGame/ZeldaIITheAdventureOfLink'', Link has to do battle against a mirror image of himself. He was so popular that "Dark Link" has shown up several times since then.
* In ''VideoGame/FinalFantasyIV'', when Cecil [[spoiler:becomes a Paladin]] he must fight a mirror image of himself to atone for his past.

[[folder: Webcomics ]]

* Played with in ''Webcomic/TheNonAdventuresOfWonderella''. Everybody in the mirror universe has the opposite moral alignment of their normal self -- except for [[ChaoticNeutral Wonderella and Dr. Shark]]. As the mirror-world's Wonderella explains it:
-->'''Anti-Wonderella:''' The opposite of neutral is still neutral!
* In ''DarkLegacyComics'', it turns out that the characters have mirror selves on the other side. The protagonists are alliance characters in World Of Warcraft, so their mirror selves are horde. This make [[http://darklegacycomics.com/287.html at least one character frustrated]] and at least [[http://darklegacycomics.com/288.html one (*2) character(s) happy]].
* ''Webcomic/{{Homestuck}}'': The Scratch mechanism in sBurb sessions basically creates these -- your ancestor will take your place in life, down to living in your house, and usually shares a decent amount of your personality as well as your Aspect in the game, but they're not a direct copy.

[[folder: Western Animation ]]

* In ''WesternAnimation/TheBatman'', Batman, Robin, and the Flash dealt with mirror versions of themselves created by the inventions of the Mirror Master.
