9->'''Wendy:''' I'm in the mirror universe. ... A parallel universe where everyone who's good is evil, and evil is good. It's like that episode of ''Series/{{Star Trek|The Original Series}}'' where Spock had a goatee and Chekov tried to --\
10'''Mirror Pip:''' ''Star Trek''. You mean the sci-fi series from the Sixties starring the great Creator/GeorgeTakei?\
11'''Wendy:''' It ''is'' an evil universe.
12-->-- ''Series/TheMiddleman'', "The Palindrome Reversal Palindrome"
13
14Often a subset of BizarroUniverse, it is an AlternateUniverse where Good and Evil characterisations are reversed, but is otherwise the same as the "real" universe - except where logically derived from this change in morality. As an example, in BizarroUniverse, the Earth is a cube. In the mirror universe, the earth is a sphere, but the MirrorSelf of TheBrigadier has a cool eyepatch.
15
16The hero in the Mirror Universe functions as the EvilTwin. The FiveManBand becomes ThePsychoRangers. Expect the loyal soldier to become a blithering coward, the [[TheStarscream backstabbing bastard]] to become a peaceful negotiator, and the [[BridgeBunnies bridge bunny]] who normally gets no lines to become a trash-talking, [[SensibleHeroesSkimpyVillains lingerie-wearing]], gun-toting, [[DepravedBisexual bisexually hyperactive]] [[DarkActionGirl ball of unleashed id]]. Oh, and [[DeckOfWildCards expect them to stab each other in the back constantly so they can one-up each other for power.]]
17
18These mirror worlds tend to get [[EnsembleDarkhorse popular with the fanbase]], who'll eagerly come up with [[EvilTwin alternate versions]] of any character not yet shown, and as a result it'll often get returned to and expanded upon to please them. The [[StatusQuoIsGod status quo]] in the mirror universe is more likely to change than the original one, probably because [[AlternateUniverseReedRichardsIsAwesome the writers are allowed to do it]].
19
20The TropeCodifier is the ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS2E4MirrorMirror Mirror, Mirror]]." In homage to this episode, it's common for an evil mirror equivalent to have a [[BeardOfEvil goatee beard]].
21
22Contrast with DarkWorld (though there are some cases where these two overlap). Not to be confused with MirrorWorld or MirrorCharacter.

32[[foldercontrol]]
33
34[[folder:Anime and Manga]]
35* ''Anime/TengenToppaGurrenLagann'' performs this in Parallel Works 4, where the Beastmen are being oppressed by Kamina, and Viral is TheHero, it actually makes Kamina look ''legitimately evil''.
36* Happened in one episode in ''Manga/{{Doraemon}}'' when Doraemon and Nobita enter and explore a mirror universe and interact with their counterparts. This universe is literally mirrored of having mirrored writing and east is west. Other differences include reversed gender roles showing Nobita's mom as the breadwinner, all males dressed as females, and different teachings in school. Nobita and his counterpart decide to [[PrinceAndPauper swap roles]] for a day.
37* The movie ''Anime/NarutoTheMovieRoadToNinja'' from ''[[Franchise/{{Naruto}} Naruto Shippuden]]'' seems based on this concept. But it is actually a incomplete version of Infinite Tskuyomi that Tobi created, a Genjutsu world influenced by the minds of whoever go transported to it with most characters exhibiting the reverse of their normal personalities. Ex. Ino becomes a prude, Shino hates bugs, etc. When Naruto and Sakura end up in the Genjutsu World, it acts on their fantasies by creating a reality where Sakura's parents sacrificed themselves for Konoha instead of Naruto's and the Akatsuki are heroes under Itachi's leadership.
38** Tenten ends up in another version of this reality in the Infinite Tskuyomi Madara casts.
39* An episode of ''Anime/PokemonTheSeriesXY'' has Ash travel into one when his Mirror Counterpart grabbed his Pikachu. The mirror counterparts of the main cast all have opposite characteristics: Ash is timid, and Pikachu is always attacking Team Rocket, who are celebrated heroes, Clemont is athletic and relies on magic, Bonnie is mature and ladylike, and Serena is aggressive.
40* ''Anime/DragonBallSuper'': Apparently, of the 12 universes that exist, they come in pairs, with each having a mirror version of it. In a twist though, the ''heroes''' home universe, the 7th, appears to be the "evil twin" universe of the 6th. In the 6th Universe, the Saiyans are a peaceful race of selfless heroes while Freeza's counterpart is [[spoiler:a planet-trading pirate, except that he puts on a friendly face to the public and is known as a great hero]]. On the other hand, 6th Universe humanity was apparently so warlike that they annihilated Earth long ago, and its God of Destruction, Champa, is more polite but also somewhat more malevolent than Beerus.
41* An episode of ''Anime/KujiraNoJosephina'' has Santi reaching his home (turn into a scary mansion) after school but in some sort of AlternateUniverse where everyone is an evil creepy version of his family.
42* One arc of ''Manga/FairyTail'' takes place in the parallel world Edolas, which is populated by opposite versions of the cast. For example, Edolas Lucy is an aggressive and stern woman, Edolas Natsu is a timid boy that enjoys driving (A contrast to main Natsu's motion sickness), and Edolas Gray bundles himself up in layer of clothes and constantly proclaims his love to Juvia (A reverse of their Earthland selves).
43* In ''Anime/YuGiOhArcV'', there are three separate worlds besides the Standard Dimension: The Xyz Dimension, the Synchro Dimension, and the Fusion Dimension. But only Yuya and his friend Yuzu each have a counterpart in those worlds, totaling up to four pairs.
44** Yuri, Yuya's counterpart from the Fusion Dimension, is his [[ObviouslyEvil opposite]] [[TheDreaded in]] [[PsychoForHire every]] [[ForTheEvulz way]]. His ace, Starve Venom Fusion Dragon is also presented as a malevolent and evil counterpart to Yuya's Odd-Eyes Pendulum Dragon. He even sports a counterpart to Yuya's [[ForHappiness Smile World]] card: [[KickTheDog Ridicule World]], which prevents the opponent from attacking while creating sinister shadows that laugh and mock them.
45[[/folder]]
46
47[[folder:Card Games]]
48* There is a set of ''TabletopGame/MagicTheGathering'' involving a plane that transforms back and forth between its mirror opposites. Lorwyn is a bright, cheery world of eternal summer and daylight, filled with the stuff of whimsical fairytales. Then the world is abruptly transformed into Shadowmoor, stuck in perpetual twilight, and filled with the stuff of the Grimm brothers. Most inhabitants change with it, believing that they've always lived in whichever world it is (which could bring with it all kinds of metaphysical uncertainty about just how often the world changes its nature).
49** Also, Time Spiral block revealed several, including a consistent one in which [[CatGirl Mirri]] instead of Crovax became the vampire evincar of Rath. Also the first male angel in Magic history.
50* In the lore of TabletopGame/SentinelsOfTheMultiverse there's the Inverseverse, an alternate universe where everyone who's good is evil and everyone who's evil is good. And Anubis... is still kind of a jerk. Though in a different way. The Action Hero Stuntman and Ivana Ramonat Luminary variant cards are from this universe.

53[[folder:Comic Books]]
54* [[ComicBookTropes Comics]] do this all the time. Franchise/TheDCU has its "anti-matter" Earth, wherein Ultraman, Superwoman, Johnny Quick, Power Ring, and Owlman (the Crime Syndicate of Amerika) are the evil duplicates of ComicBook/{{Superman}}, ComicBook/WonderWoman, ComicBook/TheFlash, ComicBook/GreenLantern, and ComicBook/{{Batman}} (the ComicBook/JusticeLeagueOfAmerica), and ComicBook/LexLuthor was the only superhero left in the world. A later story introduced the Justice Underground, a team of heroes led by ComicBook/TheRiddler's counterpart, the Quizmaster, and based on the various evil groups faced by the Justice League (such as the LegionOfDoom, the Injustice Gang/League, and the Secret Society of Supervillains). Other members of the group included Sir Solomon Grundy (a dapper and intelligent [[Characters/GreenLantern1941 Solomon Grundy]]), General Grodd ([[Characters/TheFlashRoguesGallery Gorilla Grodd]]), Lady Sonar (Sonar), Q Ranger (Major Force) and a heroic version of Star Sapphire. Following Riddler's temporary HeelFaceTurn, Quizmaster had a temporary FaceHeelTurn in ''ComicBook/Trinity2008''.
55** ''ComicBook/ForeverEvil2013'' and its lead-up introduced two new Crime Syndicate members: Atomica, an evil version of ComicBook/TheAtom, Grid, an evil version of ComicBook/{{Cyborg}} and Sea King, an evil version of ComicBook/{{Aquaman}}. Owlman was also assisted by the Outsider, an evil version of Batman's BattleButler Alfred.
56** Owlman and Talon, Batman and Robin's counterparts from Earth-3, the Evil Counterpart Universe.
57*** Talon takes it further by being a LegacyCharacter. The Talon who seems to be a direct counterpart to [[ComicBook/Robin1993 Tim Drake]] actually took a HeelFaceTurn and ended up joining the Teen Titans alongside Tim before being murdered and given back to Owlman in individually wrapped pieces.
58** ''ComicBook/DCYearOfTheVillain'' introduces Sky Tyrant, ComicBook/{{Hawkman}}'s Earth-3 counterpart.
59** The trope originated in UsefulNotes/{{the Silver Age|of Comic Books}} with Earth-3, which was destroyed in ''ComicBook/CrisisOnInfiniteEarths'' but was restored later in ''ComicBook/FiftyTwo''; the antimatter universe was based on this concept. Since the New 52, Earth-3 has effectively become the DCU's primary mirror.
60** Creator/GrantMorrison's ''ComicBook/JLAEarth2'', the graphic novel that re-introduced the "anti-matter" version of the Crime Syndicate, [[DeconstructedTrope deconstructed the trope]]: even the ''TheoryOfNarrativeCausality'' was reversed in the mirror universe, so the Justice League's attempt to save it was as doomed as the Syndicate's attempt to conquer Franchise/TheDCU.
61** Power Ring is an interesting example. Since Hal Jordan was Earth-1's only Green Lantern at the time, Power Ring was originally a Mirror Universe version of Hal. However, as time has gone on and [[LegacyCharacter multiple heroes have used the Green Lantern name]], the Syndicate's Power Ring has been altered a few times to resemble later Green Lanterns like Kyle Rayner and John Stewart. During the "Syndicate Rules" storyline, Power Ring was even given an in-universe RaceLift changing him from a blonde white man to a bald African-American man to reflect John replacing Kyle as the Justice League's primary Green Lantern, with the new look explained as a CosmicRetcon caused by the destruction and rebirth of the Antimatter Universe during ''ComicBook/JLAAvengers''. Then, following Hal Jordan's resurrection during ''ComicBook/GreenLanternRebirth'', Power Ring changed ''back'' into a Hal analogue, with Ultraman even remarking on the sudden change.
62** ''ComicBook/YoungJustice2019'' Issue #8 introduces the team's [[MirrorUniverse Earth-3]] counterparts: Amaxon Thunder for ComicBook/WonderGirl, Luthor-El for ComicBook/{{Superboy}}, Speed Zone for Impulse, Hack for Teen Lantern, Hex for Jinny Hex and Drake for Tim Drake. We never meet ComicBook/{{Amethyst|Princess Of Gemworld}}'s counterpart as she apparently overslept and missed the fight.
63** The 2021 ''ComicBook/{{Crime Syndicate|2021}}'' mini-series introduces a new take on the team that explores Earth-3 in greater detail. The core group once again includes Ultraman, Superwoman, Emerald Knight (the [[AdaptationNameChange renamed]] Power Ring, who is now a John Stewart analogue once again), Johnny Quick, and Atomica, while Earth-3's ComicBook/{{Vixen}} and Red Star counterparts appear for the first time.
64*** The animated ''WesternAnimation/JusticeLeague'' also had the Justice Lords universe - a variation on the regular DCAU in which the death of ComicBook/TheFlash resulted in the League/Lords becoming a totalitarian dictatorship. The arc began life as a movie about the Crime Syndicate but was retooled to a more iron-fisted Justice League. Without explicit ties to any past work, the original idea finally saw light years later as ''WesternAnimation/JusticeLeagueCrisisOnTwoEarths'', which applied the concept to a large amount of Justice League characters. In addition to the primary Crime Syndicate members, Mirror Universe versions of ComicBook/MartianManhunter, [[ComicBook/{{Hawkman}} Hawkgirl]], ComicBook/GreenArrow, [[ComicBook/{{Shazam}} the Marvel Family]], Justice League Detroit, ComicBook/{{The Outsiders|DCComics}} and others are also seen. A heroic version of ComicBook/TheJoker called the Jester shows up at the beginning, while the American president is [[ComicBook/{{Deathstroke}} Slade Wilson]].
65** The idea is also used with the Injustice Syndicate in ''WesternAnimation/BatmanTheBraveAndTheBold''. In addition to Owlman, the group includes Scarlet Scarab (ComicBook/BlueBeetle, specifically the Jaime Reyes version), Barracuda (Aquaman), Blaze (Fire), Blue Bowman (Green Arrow), Dyna-Mite (the Atom, specifically the Ryan Choi version), Rubber Man (ComicBook/PlasticMan) and Silver Cyclone (ComicBook/RedTornado). Their enemies are the Justice Underground, whose ranks include the Red Hood (the Joker), Yellow Lantern (Sinestro), General Grodd ([[Characters/TheFlashRoguesGallery Gorilla Grodd]]), and unnamed heroic versions of C and D-list villains like Clock King, Kite-Man and Gentleman Ghost.
66** A similar universe appears in ''ComicBook/InjusticeGodsAmongUs'', where Superman became evil and totalitarian after the Joker tricked him into killing Lois Lane.
67** ''ComicBook/TheMultiversity'' introduced two pulp-themed parallel universes, where one is the Mirror Universe to the other.
68** ''ComicBook/Superboy1994'': Black Zero, an evil alternate of Superboy, comes from an earth where Donovan and Westfield got their way and were able to control Superboy and most of the world's heroes were slaughtered and replaced with twisted Cadmus created and controlled clones.
69** Issue #48 of ComicBook/TeenTitansGo, the tie-in comic to the WesternAnimation/TeenTitans cartoon, revealed that new electricity-based Titan Kilowatt was from an alternate universe, and Raven used her powers to help him go back to his world, but something went wrong and he was accidentally transported to a universe where the Teen Titans are instead the villainous Teen Tyrants. [[MythologyGag Mythology Gags]] abound as Evil Robin, Speedy, and Aqualad are referred to as "Red Robin", "Arsenal", and "Tempest"; Evil Starfire and Raven are called "Blackfire" and "Red Raven". Their enemies are the Brotherhood of Justice, the [[GoodCounterpart Good Counterparts]] of the Brotherhood of Evil.
70** Also, most of these incarnations have Alexander Luthor as [[GoodCounterpart the good version]] of the main ComicBook/LexLuthor, contrasting the Crime Syndicate. This is averted in ''ComicBook/ForeverEvil2013'' however with a Luthor as bad as his mainstream counterpart, since [[CrapsackWorld this Earth-3 lacks good, period.]]
71** There's [[Characters/DarkNightsMetal The Batman who Laughs]], the LaughingMad EvilTwin of Batman from an AlternateUniverse where he was poisoned with Joker Gas, went insane, and massacred the Bat-Family, turning into a terrifying supervillain. Worse still, The Batman who Laughs has all of good Batman's CrazyPrepared skills, making him all the more dangerous. Ironically it takes an EnemyMine situation between both Batman and The Joker to bring The Batman who Laughs down.
72** One issue of ''ComicBook/TinyTitans'' saw Talon try and summon a group of evil Tiny Titans from an alternate dimension. Despite his insistence that this trope should be in play, however, it ends up subverted -- the alternate Titans are nigh-identical to the main universe Titans, with the only big differences being their names (sans Robin's counterpart, who also goes by Robin) and the colors of their costumes (in their universe, [[GoodColorsEvilColors red and yellow are evil colors while green and purple are hero colors]]).
73* ''ComicBook/{{Exiles}}'', of the Franchise/MarvelUniverse, had an issue where ComicBook/{{Galactus}} restored worlds instead of eating them, and the Silver Surfer was a power-hungry despot who had destroyed his own homeworld. The first issue of ''Exiles'' was in a universe where Magneto was the benevolent teacher who wanted mutants and humans to live in harmony, and Professor X believed there could only be peace when humanity was eradicated.
74** The ''ComicBook/AgeOfApocalypse'' has elements of this trope; ComicBook/{{Magneto}} leads LaResistance - including a GoodIsNotNice version of ComicBook/{{Sabretooth}} and a version of Colossus who is a psychotic AntiHero - and there is a human resistance including a heroic Doctor Doom and Sentinels actually protecting mankind, versus a dystopic mutant tyranny whose ranks include [[TheHero Cyclops]] and his brother [[TheLancer Havok]] as well as [[TheSmartGuy Beast]], now known as Dark Beast, as well as a new character called Abyss who was later introduced into the mainstream comics as a heroic character. However, though Dark Beast is a cruel and sadistic MadScientist and a despicable piece of work, Cyclops is just an AntiVillain who does a HeelFaceTurn, and as the title suggests this is a world where recurring ComicBook/XMen villain ComicBook/{{Apocalypse}} has achieved world domination and if anything has actually gotten ''worse''; other villains like [[EvilutionaryBiologist Mister Sinister]] merely serve as his minions and are still evil, while most heroes and villains from other parts of the Marvel Universe didn't change sides, they were just killed when Apocalypse nuked the United States and started purging humanity.
75** Played with in the ''ComicBook/MarvelZombies'' universe; the heroes are all evil, but only because they succumbed to a ZombieApocalypse and proceeded to devour most of the human race, though they are [[OurZombiesAreDifferent sentient zombies]] who take sadistic pleasure in ripping their [[ImAHumanitarian meals]] apart. Magneto and Doctor Doom show up as their enemies and help rescue survivors, but mostly in the context of them being NobleDemon types who [[EvilVersusOblivion object to rampaging malevolent zombies]] [[ApocalypseHow wiping out the entire universe]]. The cause of mutant supremacy doesn't matter much when most mutants and non-mutants have made peace with each other and decided just to eat everyone else.
76** ''ComicBook/TheThanosImperative'' features the Cancerverse, a universe where [[TheProblemWithFightingDeath Death has been wiped out]] by four powerful demons called the Many-Angled Ones, including ComicBook/DoctorStrange villain Shuma-Gorath (like the other three, a unique multiversal entity -- it has no [[EvilTwin good twin]] anywhere in the multiverse). Life has become pollution and is spiraling out of control, and every living thing in the universe is BrainwashedAndCrazy and are fanatically devoted to worshipping the evil entities, though non-living beings like the Vision (a robot) are immune and still heroic. Thus, in this universe hero teams like ComicBook/TheAvengers are the servants of evil gods, though presumably so is every living villain as well.
77* ''ComicBook/SonicTheHedgehogArchieComics'': It has a Mirror Universe, called variously "The Reverse Universe", "Anti-Mobius", and "Moebius". In it Dr. Robotnik/Kintobor is a KindlyVet, while the Freedom Fighters fight against freedom, having overthrown the previous monarch. The Anti-Freedom Fighters (name later changed to the Suppression Squad) all dress in black leather, and acted like a bunch of juvenile delinquents until Anti-Sonic became "Scourge" and conquered Moebius.
78** The interference from the heroes' world has caused the parallels to break down a bit; Scourge has been turned green and hooked up with [[FaceHeelTurn Fiona Fox]] for a while, Anti-Bunnie has pulled a HeelFaceTurn and wears [[PoweredArmor Omega Armor]] instead of being a {{cyborg}} (anti-Rotor is the cyborg) and anti-Antoine briefly posed as his good counterpart. Basically the [[StatusQuoIsGod status quo]] for the mirror world gets altered more often than the main one. Oh, and [[TheStarscream Miles Prower]] even has [[BeardOfEvil the goatee]].
79*** Sonic has a direct evil double in the form of Scourge the Hedgehog. Unlike Shadow, who often acts as a foil to Sonic, and Metal Sonic, which is a robot built to serve Dr. Eggman's diabolical purposes, Scourge is literally an evil counterpart: He is Sonic from a parallel dimension, where the protagonists and villains switch roles. In the early days of the comic, Scourge was simply known as "Anti-Sonic" and was identical to Sonic save for sunglasses, a black leather jacket, and a JerkAss attitude. However, after some vocal exchange with Sonic, Anti-Sonic became shaken up by the thoughts and sought to make himself stand out. To that end, he attempted to hijack the Master Emerald. The result was becoming green, getting some scars on his chest and a form of rebirth. This is where he christened himself Scourge the Hedgehog and he was now much more ambitious than ever before, even becoming king in his unvierse.
80*** He then forces this on his Anti-Freedom Fighters, turning them into the Suppression Squad. Not only are they just as bad, they followed Scourge's example in changing their names from their counterparts (such as Anti-Sally calling herself Alicia) to further stand out from them. Princess Sally's counterpart, Alicia, is nothing more than a figurehead. Miles, Tails' counterpart, is cold, calculating, and the ''real brains'' behind the team. Rotor's counterpart, Boomer, took his genius and used it on himself, turning himself into a cybernetic terror (which also makes him Bunnie's evil counterpart) Patch, Antoine's evil counterpart, is completely vain and in it for power. {{Subverted|Trope}} with Anti-Bunnie; she ended up becoming good (kinda) when she ended up contracting NIDS and her teammates left her to die. She was saved by Dr. Kintobar via a special mech suit (resembling Omega oddly enough) and she became his bodyguard as a result while now calling herself Buns.
81** ''ComicBook/SonicTheComic'' featured [[https://sonic.fandom.com/wiki/King_Sonic King Sonic]], hailing from a MirrorUniverse in which Sonic was the one who got caught in the explosion of the Retro-Orbital Chaos Compressor instead of Dr. Kintobor. As such, in the absence of Dr. Robotnik, this Sonic became the tyrant that sought to take over his universe's Mobius. He has all of Sonic's abilities with none of his redeeming qualities and even has his own [[SuperpoweredEvilSide Superpowered Good Side]] in King Super Sonic.
82* Subversion: In Creator/PhilFoglio's short story [[http://www.girlgeniusonline.com/stories/HBstory/HBstory.php "Work Ethic"]] found in ''ComicBook/GrimJack'' #40, heroes from a world in which there is only pure good and pure evil (and the heroes always win), get transported to Grimjack's world, which has a more realistically varied moral spectrum. Thus, since they see that everything is not purely good, they begin to destroy the entire town of Cynosure until Cynosure's protector sends them back to their own dimension. (Incidentally, these heroes, the Heterodyne Boys, later became the inspiration for ''Webcomic/GirlGenius''.)
83* Similarly, in ''ComicBook/JLAAvengers'', the League, seeing the many imperfections of the Franchise/MarvelUniverse, conclude that it's the Evil Universe. ComicBook/TheAvengers, seeing statues and museums to the heroes everywhere in the Franchise/DCUniverse, conclude the exact same thing (they think the DC heroes have set themselves as gods).
84* In the ''ComicBook/XMen'' [[AlternateUniverse alternate earth]] where Charles is Juggernaut, he ruled Earth as a dictator showing just how evil he would've been if not for his bullying big brother taking the Gem for himself. Several other "Evil Professor X" universes appear in ''ComicBook/{{Exiles}}'', sometimes with him balanced by a heroic Magneto.
85* ''ComicBook/JudgeDredd'':
86** ''2000 AD'' continuity: Deadworld is a mirror image of the 'real' world which is ruled by four Dark Judges, supernatural beings who consider all forms of life to be punishable by death (their philosophy being that [[TheEvilsOfFreeWill only the living commit crimes]]). There are hints that Deadworld was more-corrupt than Dredd's world. Life was viewed more cheaply than in Mega-City One, and the Judges wore all-black uniforms. Judge Death, still an ordinary human, joined up so he could kill people with impunity. He had already killed several classmates in secret, but on his first day on the job, he executed all 27 offenders. Eventually his philosophy started to catch on with the other Judges. There was a growing resistance movement to the Judges at this point, but the Chief Judge was too slow to act, and Judge Death overthrew him in a coup, renaming his courtroom the "Hall of ''In''justice." Also around this time, a team of undead priestesses called the Sisters of Death set up shop on Deadworld, which coincided with other problems such as crop failures. The Dark Judges attracted the attention of the Sisters and were transformed into undead creatures. After the Dark Judges outlived their usefulness, Death butchered all of them--sparing only his three closest friends, who were just as insane as he. (Judge Fuego a.k.a. Judge Fire was infamous for having burned down a school over noise violations.)
87** The AlternateContinuity of the short-lived ''Judge Dredd: Lawman of the Future'' comic (a more kid-friendly title featuring the uniforms from [[Film/JudgeDredd the Stallone movie]]) takes this a step further: In his first encounter with Judge Death, Dredd learns that the undead monster is [[EvilTwin a future version of himself]], which wasn't the case in the main-continuity Deathworld.
88* ''ComicBook/TransformersShatteredGlass'', where the heroic Decepticons are fighting to protect Earth and Cybertron from the power-mongering of the evil Autobots. "Till All are Gone..." And yes, [[http://tfwiki.net/wiki/Image:Rodimus_goatee.jpg Evil Rodimus has a goatee.]]
89** Quintessons are tree-hugging, peace-loving, groovy lingo-speaking, space-hippies. The major Quintesson character is an exile who disagrees with the usual Quintesson policy of non-interaction with races until they're deemed sufficiently advanced -- as opposed to the normal Quintesson policy of enslaving or arbitrarily executing "inferior" beings.
90** [[TheStarscream Starscream]] is Megatron's [[UndyingLoyalty most loyal soldier who praises his commander]]. (It's all rather creepy, to be honest.) He also bears the color of his normal universe friend-turned-foe, Jetfire.
91*** Even speech patterns are reversed: [[HulkSpeak Grimlock]] is [[AntiquatedLinguistics sophisticated]], [[MachineMonotone Soundwave]] talks like a SurferDude, [[JiveTurkey Jazz]] sounds like Creator/MrT, and so on.
92** Earth is a CrapsackWorld that views both factions of Transformers as enemies. But more illustrative of the [[BizarroUniverse reversed nature of the universe]] are the Witwicky brothers, who are now petty criminal allies of the evil Autobots, and the machine-hating Creator/MarvelComics villain Circuit Breaker (or Josie Beller), whose ''Shattered Glass'' counterpart is Josephine "Sephie" Beller, an ordinary human Decepticon ally who loves machines and admires the Transformers. The MadScientist Dr. Arkeville's counterpart is Professor Henri Arkeville, a ScienceHero. The cruel dictator Abdul Fakkadi's counterpart is a benevolent ruler who is a father to his people. Cobra is a resistance unit fighting for freedom against America's tyrannical enforcers: Franchise/GIJoe.
93** Nobody in this universe has heard of beings like [[{{God}} Primus]], [[GodOfEvil Unicron]], or [[{{Satan}} The Fallen]]. When a displaced G1 Cliffjumper explains the concept to Megatron and the other Decepticons, they find the idea quaint. It should be noted that these beings are multiversal singularities (there is only one version of them in the multiverse), so if they ever showed up in the Shattered Glass-verse, they would be the same as in the normal universe. There is an evil Alpha Trion, however.
94*** Though that changed following the Shroud, which caused the multiversal singularities to split into a counterpart for each universe. Thus there's now a good Unicron and an evil Primus.
95** Earth also has a Franchise/MyLittlePony, where they have unfriendly sounding names, like Rainbow Dark and Poison Apple (likely evil counterparts of [[WesternAnimation/MyLittlePonyFriendshipIsMagic Rainbow Dash and Applejack]], respectively).
96* ''ComicBook/DisneyMouseAndDuckComics''
97** ''ComicBook/DisneyDucksComicUniverse'' also dabbled in this; [[http://coa.inducks.org/story.php?c=I+TL+2355-5 in this comic,]] Paperinik ends up going into an alternate universe where Uncle Scrooge is poor, Gladstone Gander is unlucky, policemen are criminals, criminals are good, and Paperinik himself is evil.
98** ''ComicBook/MickeyMouseComicUniverse'':
99*** In one series of comics, it's especially disconcerting in that the Phantom Blot, a ManipulativeBastard and trademark villain, is a superhero.
100*** In the Italy series ''X-Mickey'' we find Mickey traveling through portals to another dimension and meeting new characters that are special for this series. Most notable is the Goofy-lookalike werewolf named Pipwolf, but we also have Manny that looks like an albino Minnie, and several other characters that are recurring throughout the series.
101* ComicStrip/MandrakeTheMagician has had several adventures involving a mirror universe. Usually the evil mirror universe tries to invade the ordinary universe, coming through just about any mirror (though they prefer to begin with Narda's), since they have a spray that makes mirrors soft and permeable.
102* ComicBook/ThePowerpuffGirls comic "Deja View" involved the Powerpuff Girls' adventures through a universe in which they must help the heroic Jomo Momo (Mirror Mojo Jojo) defeat Oppressor Plutonium (Mirror Utonium). Meanwhile, the girls' counterparts, the Powerpunk Girls, wreak havoc on Townsville. This was originally going to be a season five episode for the TV show, but its CGI put it over budget and near a tight deadline. They gave the storyline to DC Comics to make as issue #50.
103* The 7th arc of the [[ComicBook/MyLittlePonyFriendshipIsMagicIDW My Little Pony: Friendship is Magic comic book series]] deals with the mane six (plus Spike) traveling to another dimension where the villain of [[Recap/MyLittlePonyFriendshipIsMagicS3E1TheCrystalEmpirePart1 the season 3 premiere]], King Sombra, is actually TheGoodKing while the counterparts of Princess Celestia and Princess Luna are the villains. Other changes include the mane six's counterparts being pictured on wanted posters while various antagonists throughout the series are depicted as heroes. Some characters' traits are reversed; ie the Apple family are snobby aristocrats instead of humble farmers.
104* The ''ComicBook/{{Planetary}}''[=/=]''JLA'' one-shot is set in an alternate timeline where the main characters from ''Planetary'' are evil and playing the role that their enemies the 4 do in the main timeline, with JLA characters introduced as the heroes trying to take them down.
105* The ''ComicBook/TomStrong'' stories "Too Many Teslas" and "The Many Worlds of Tesla Strong" both depict a very large number of alternate universes to the main Tom Strong universe, including a Mirror Universe in which Tiberius Strong and his daughter Twyla Strong are both villains, and Nazi Germany was a tragically-short-lived utopia that saved the lives of millions of people.
106* The ''Mices on Infinite Earths'' storyline in Creator/MarvelComics' ''WesternAnimation/MightyMouse'' comic, being a parody of ''Crisis on Infinite Earths'', introduced Earth-Not, ruled with an iron fist by Mangy Mouse, Mighty Mouse's EvilTwin with [[PaletteSwap reversed costume colours]] (red suit, yellow cape).
107* ComicBook/TheVision has Anti-Vision, his [[EvilTwin crooked doppelgƤnger]] from a parallel universe.
108* In ''ComicBook/MightyMorphinPowerRangersBoomStudios'', there's Lord Drakkon, an alternate reality version of Tommy Oliver/Green Ranger who, upon being freed from the Sword of Darkness and offered a hand in friendship, ran back to Rita. He became drunk on power and ultimately destroyed the Power Rangers and [[TheStarscream killed Rita and took her place]].
109* ''ComicBook/ArchieComics'': One issue had Archie and Chuck stumble into a backward version of Riverdale where everyone's personality (including theirs) was inverted. The most extreme case was Jughead, who goes from a practically asexual glutton to a skirt-chasing pervert who hates food so much that he ''blows up a bridge'' to stop food shipments from entering town.

112[[folder:Fan Works]]
113* The RPG.net forum discussion ''[[http://forum.rpg.net/showthread.php?t=413172 Shattered Disc]]'', a mirror universe Literature/{{Discworld}}. "The world burns ... on the back of a turtle."
114* ''Fanfic/MyStupidReality'', a ''Manga/DeathNote'' fic in which the Light vs L conflict is reversed - in this universe, Light is a genuinely NiceGuy who has spent all his life pretending to be ''imperfect'' and it's ''L'' that [[JumpingOffTheSlipperySlope jumps off the slippery slope.]]
115* Also the ''Manga/DeathNote'' [[AlternateUniverseFic AU]] ''Fanfic/TheFacelessDisguiseOfCarnivorism''- in canon Light [[spoiler: kills L]] [[VillainWithGoodPublicity but is seen as admirable by the men he's deceived.]] In this universe, Light [[spoiler:rescues L]] and is met with derision by his soldiers as they realize the AwfulTruth about what they were fighting for.
116* Among ''TabletopGame/Warhammer40000'' fans, there is practically an entire genre built around "What if the ''Literature/HorusHeresy'' had the loyalists and traitors switch places?"
117** Perhaps the original in this genre is ''FanFic/TheDornianHeresy'' which switches the places of the loyalists and traitors, and in almost every major event the alternate choice was made. [[spoiler: The Emperor sided with Magnus during the Council of Nikea, and Magnus privately requested that the Emperor perform the soul-binding ritual on him and the Thousand Sons to protect them from the influence of Chaos, meaning that the Thousand Sons gained the power to banish and in some cases even outright destroy daemons. Angron had Horus and the Emperor side with him during the slave uprising on his world, resulting in him removing the combat implants in his warriors. After the Heresy, the Legions were never broken up to make sure they could stay strong and root out traitors within their ranks. Ultramar was tricked into fighting the Alpha Legion and Word Bearers, resulting in them becoming a third power, meaning that they were no longer held by the rules of the Imperium and began to tinker with their technology. Lorgar chose to declare a holy war upon Chaos rather than siding with them. And, most shocking of all, [[GeneralFailure Abbadon]] became a tactical genius!]]
118** Perhaps a more well-known story is that of ''FanFic/TheRoboutianHeresy''. As the name implies it is Roboute Guilliman who leads the rebellion against the Emperor.
119* ''FanFic/YouGotHaruhiRolled'' features an EvilCounterpart of the SOS Brigade, who hail from a literally photonegative universe. The Anti-SOS Brigade (the canonical EvilCounterpart) offers to help them kill the SOS Brigade, but [[EvilerThanThou are betrayed by the photonegative SOS Brigade]] [[MyFriendsAndZoidberg (and Evil Tsuruya)]].
120* ''Fanfic/TheSacredAndTheProfane'' is a DarkerAndEdgier retelling of ''Literature/GoodOmens'' where Crowley (now known as Caphriel) is the angel and Aziraphale (now Zirah) is the demon.
121* A ''Manga/{{Bleach}}'' fanfiction features Sonoma and Kan'na. Sonoma is the original universe, introduced in the works of Tite Kubo. Kan'na is a universe created by a user and is the parallel twin universe to Sonoma. Kan'na is war-torn, and the World of the Living is in a post-apocalyptic state, having been overrun by Hollows. Morals and standards do not exist in Kan'na, same for rules.
122* ''Fanfic/ReimaginedEnterprise'' uses the TropeNamer once per season, using similar concepts to the acclaimed "In A Mirror, Darkly" episode from the canon show.
123* A group of ''Franchise/TheTransformers'' fans [[http://web.archive.org/web/20081207033622/http://mirrorverse.transfactions.net/main.html wrote several pieces about a possible Transformers mirror universe,]] with the [[http://web.archive.org/web/20081204111332/http://mirrorverse.transfactions.net/fic/closer.html first such piece]] appearing in 2001, predating the Shattered Glass universe by around seven years (as ''Shattered Glass #1'' appeared in 2008). This fan-made Mirror-verse setting was unusual in that its good and evil flip was played completely straight (with the evil Autobots proving to be even more monstrous than the Decepticons of the normal universe), where Shattered Glass has hints of clever parody in its content.
124* ''WesternAnimation/DarkwingDuck'' already had a mirror universe in the form of the Negaverse. ''FanFic/NegaverseChronicles'' explores that world extensively.
125* During the 'Good and Evil' chapter of ''FanFic/VariousVytalVentures'' we see a glimpse of such a world, where RWBY is a team of PsychoRangers, Ozpin is an EvilOverlord, and almost everyone has their personality completely swapped. Naturally, it makes several {{Shout Out}}s to the original ''Franchise/StarTrek Mirror''-verse.
126* In ''Fanfic/TheBridgeMLP'', several good and bad {{Kaiju}} get transported to Equestria. In the spin-off ''The Bridge: Sound of Thunder'', Raiga finds herself in Equestria and thinks she will soon be reunited with Godzilla and her other friends, except it turns out she arrived in the mirror Equestria from ''ComicBook/MyLittlePonyFriendshipIsMagicIDW''. To make matters worse, the Kaiju transported to this world are from a mirror universe as well. Godzilla is a sadistic murderer instead of a hero, ''Battra'' Lea is an OmnicidalManiac instead of a guardian, etc. On the flip side, Xenilla and Destroyah are heroes instead of villains. Raiga's own counterpart is shy and meek instead of fight-happy.
127* The ''Fanfic/ThisTimeRound'' MetaFic setting for ''Series/DoctorWho'' has Some Other Time Round, where the author avatars are nastier, the stories are darker, and the canon characters are from "Inferno".
128** Curiously enough, there's no evil version of the Doctor himself (although the ExpandedUniverse novels did suggest that the evil tyrant ruling this fascist alternative Britain was in fact an alternative version of the Third Doctor with a different body who went evil after his forced regeneration by the Time Lords).
129* Given that the ''VideoGame/{{Undertale}}'' fandom is a breeding ground for [[AlternateUniverse Alternate Universes]], it's not surprising that one of these exists - ''Fanfic/{{Underfell}}'', where the monsters were forced to [[JerkWithAHeartOfGold bury their kinder natures]] and "kill or be killed" is the law of the land. Typically, [[BigBad Flowey]] becomes the player's partner and guide, while [[AllLovingHero Papyrus]] becomes a vicious sadist ([[MinionWithAnFInEvil or at least tries to be]]), [[EndearinglyDorky Alphys]] becomes a MadScientist, Undyne and Mettaton both become significantly more vicious, Toriel becomes MyBelovedSmother or an EvilMatriarch, and Asgore is a dictator and unrepentant child-murderer. And everything generally looks DarkerAndEdgier. Some interpretations put a little more emphasis on the ''[[AntiVillain looks]]'' part, turning it more into a human intimidation tactic than anything truly genuine.
130* The ''Webcomic/{{Terinu}}'' fanfic "The Grace of God" has the mainline characters drop into a parallel universe where their personalities were twisted in the worst possible direction. Leeza is the obedient military officer her father always wanted, Terinu is Mavra Chan's loyal enforcer, Melika is a SpacePirate, and Rufus warped from an honorable AcePilot to a drunk, drug-addicted wreck.
131* The ''Franchise/{{Danganronpa}}'' fanfic ''FanFic/ThroughTheCrackedMirror'' reverses the roles of Hope and Despair.
132* From the ''WesternAnimation/GravityFalls'' fandom comes the FanFic/ReverseFallsAU, in which Dipper and Mabel (often but not always given the surname "Gleeful") are a pair of ruthless, sometimes [[DarkFic outright]] AxCrazy CreepyTwins. More often than not Mabel will be a StalkerWithACrush to the now-heroic Gideon, while Dipper begins a much more... [[BelligerentSexualTension belligerent]] relationship with Pacifica. That is, if the setting isn't just an excuse to write an inverted [[MindGameShip BillDip]] fic.
133* ''WesternAnimation/StevenUniverse'''s take on this is the Momswap AU, where the homeworld gems Jasper, Lapis Lazuli, and Peridot take the place of Garnet, Amethyst, and Pearl as Steven's surrogate moms and the rebels fighting for Earth, while the canon Crystal Gems are the threatening Homeworld gems. Sometimes [[BigBad Yellow Diamond]] is Steven's mother instead of Rose Quartz, and sometimes ''everyone'' is swapped- even Steven. It all depends on what interpretation you're talking about.
134* ''TabletopGame/Warhammer40000'' has a Mirror Universe fic called ''FanFic/TheRoboutianHeresy'' where instead of Horus leading a rebellion against The Emperor, it is Roboute Guilliman, and the Loyalist/Traitor legion split is reversed.
135* ''Fanfic/EarthsAlienHistory'' has one inspired by the ''Star Trek'' example. In this universe [[TheAlliance TeTO]], defeated in the Mekon War and gripped with revanchism and xenophobia, recreates itself as the Terran Empire in order to ensure its place as a Great Power of the galaxy.
136* ''Manga/CellsAtWork'' has the "Black Blood Cell" universe, where the cells play up the "sexy and sadistic" angle of Mirror Universes. Downplayed in terms of role, as their purpose still usually remains to protect the body rather than destroy it.
137* The ''Fanfic/EmpathTheLuckiestSmurf'' story "Smurfed Behind: The Other Side Of The Mirror" introduces a Mirror Universe where the Smurfs in it are [[RedAndBlackAndEvilAllOver all red-skinned, mostly wear black, and are all evil all the time]], with most of the male Smurfs being {{Depraved Bisexual}}s and Smurfette being [[ReallyGetsAround a promiscuous adulteress]] [[ParentalIncest who is married to Papa Smurf]], and where their main adversary Gargamel is always good. The Psyches, who are [[BlueAndOrangeMorality morally ambiguous]] in the normal universe, are shown to be opposites in the least in being emotionally liberated instead of emotionally suppressed, and team up with the normal universe's Polaris Psyche to act as allies against the Mirror Universe Smurfs. True to the title of the story, the way to that universe and back is through a MagicMirror called the Janus Mirror, which appears in both universes as a gateway.
138* ''Fanfic/RWBYDark'' is an alternate universe where the canon villains like Cinder, Mercury, Emerald, Roman, Neopolitan, and Salem are all reimagined as a heroic resistance against the vile Lord Ozpin and his army of Huntsmen and Huntresses, while heroes like Ruby, Weiss, Blake, and Yang are reimagined as serial killers, corrupt executives, genocidal terrorists, and feral savages.
139* In the ''WesternAnimation/MiraculousLadybug'' fanfic ''[[https://archiveofourown.org/works/22550647 Funhouse Mirror]]'', a brush with an akuma leads to Alya meeting her own mirror universe counterpart, whose personality consists of all the RonTheDeathEater cliches Alya tends to get hit with in fanworks.
140* ''Fanfic/TheNewAdventuresOfInvaderZim'': In Season 2 Episode 7, an accident with some cosmic energy during a fight sends all three teams into an alternate universe where everyone's morality and personalities are flipped. Among other things, [[VillainProtagonist Zim]] and [[TheRival Tak]] are heroic agents of the Irken Federation trying to peacefully uplift humanity, [[ConsummateProfessional Tenn]] is a lazy hedonist, [[BombThrowingAnarchists Nyx]] is a bland corporate drone, and [[TheHero Dib and the twins]] are supervillains out to TakeOverTheWorld.
141* ''[[https://www.fanfiction.net/s/10071646/1/Forever-Evil Forever Evil]]'' gives Owlman to Batman -- his doppelganger from a morality-inverted universe who's very much a SocialDarwinist crime boss. Interestingly, Owlman is ''much more'' openly affectionate and doting towards his sidekick than Batman. He's still a horrendous ParentalSubstitute due to his deep {{Yandere}} tendencies.
142* In ''[[http://alaxr274.deviantart.com/gallery/37280372 Hottie 3: The Best Fan Fic in the World]]'', Judas Blythe, who is from an AlternateUniverse, is the evil counterpart of Blythe Baxter from ''WesternAnimation/LittlestPetShop2012''.
143* ''[[https://forums.nrvnqsr.com/showthread.php/137-Shattered-Heaven Shattered Heaven]]'' plays this pretty straight for ''Fate/stay night'', with Archer traveling to a universe where [[TheHero Shirou]] is a sadistic megalomaniac, Gilgamesh is basically nice but a pathetic wreck, and Sakura is an asexual tsundere. Its sequel, ''[[https://forums.nrvnqsr.com/showthread.php/2629-Shatteraxia Shatteraxia]]'', is the equivalent to ''Fate/hollow ataraxia'', with the twist that the two universes wind up combining in, well, fragments, just like ''ataraxia'' shows bits of the original ''stay night'' routes mixed together.
144* There's an arc in the ''Anime/YuGiOh'' fic ''Fanfic/ChaosEffect'', set in-between Duelist Kingdom and Battle City, where [[SelfInsert Edwin]], Tristan, Tea, and [[OriginalCharacter Tea's sister Yuri]] are sucked into a morality-flipped universe, where everything has a punk dystopian aesthetic and [[spoiler: Solomon Moto]] rules Domino City with an iron fist. Edwin, being GenreSavvy, takes the time to educate the others on this trope and its variations when helping them adjust to what's happened to them.
145* Discussed in ''Fanfic/AmbitionOfTheRedPrincess''. While the DC Comics of Naofumi's world has ComicBook/{{Superman}} and ComicBook/{{Batman}} as heroes, Motoyasu's world has Ultraman and Owlman, the evil counterparts from the Crime Syndicate, as fictional heroes. Both heroes even wonder if their own real worlds are mirror universes of each other.
146* ''[[https://archiveofourown.org/works/28358898/chapters/69481488 Dark Mirror]]'' is a ''WesternAnimation/Ben10'' fanfic that re-tells the original series but switches around the positions of the heroes and villains, making the Plumbers a corrupt KnightTemplar organization (with Max having been fed enough propaganda that he refuses to consider that they might be in the wrong at first) and Vilgax the BigGood among other things. However, Ben and Gwen are still as heroic as they were in canon, and as a result characters who were members of their RoguesGallery in canon end up becoming their allies here.
147* ''Fanfic/HalloweenUnspectacular'': The fifth edition story "The Other Side of the Mirror" shows a world where an alternate version of [[WesternAnimation/AvatarTheLastAirbender Aang]] leads the oppressive Empire of the Sky alongside a council of counterparts to other Nicktoons characters, all of whom see no problem with sentencing a freedom fighter version of Azula to forced labor with her civil rights stripped away.
148* {{Downplayed}} in ''Fanfic/TheWrongReflection'', a ''VideoGame/StarTrekOnline'' fanfic dealing with the TropeNamer. The makeup of the prime universe Captain Kanril Eleya's crew means there physically ''can't'' be a straight-played evil version of the USS ''Bajor'': In ''Series/StarTrekDeepSpaceNine'' Bajor is part of the Klingon-Cardassian Alliance in the mirror universe--the Occupation of Bajor was perpetrated by ''humanity'' and they were freed by the Alliance conquest--but most of the members of Eleya's senior staff are Terran species. So instead other things get changed: Mirror Kanril is the XO on a Cardassian battleship and a darker version of the AntiHero compared to the PragmaticHero Eleya.
149* In chapter 5 of ''[[https://archiveofourown.org/works/45447778/chapters/122741005 DIO messes up the timeline]]'', DIO's efforts to make a timeline [[SetWrongWhatWasOnceMadeRight where he gets together with his adopted sister Johanna Joestar]] creates a world where Johanna's mother Mary survives her canon death [[TheCorruption by using the Stone Mask to become a cruel vampire]]. The result is a world where the Joestar family are now the embodiment of AristocratsAreEvil, with Mary ruling the Joestar estate with sadistic glee and feeding on injured patients, Goerge is a corrupt businessman and essentially a SycophanticServant to his wife, and Johanna an arrogant and cruel heiress that treats Dio (who in the new timeline is an AdoptAServant) as her plaything, [[spoiler:before becoming a vampire herself]].
150* There is a subgenre of ''WesternAnimation/AvatarTheLastAirbender'' fanfiction in which the Water Tribes are the ones who launch the war rather than the Fire Nation, typically with Zuko and Azula swapping roles with Katara and Sokka. Downplayed in that Aang himself is usually still TheHero, although he is sometimes subbed out for another Avatar.
151* The main draw of the ''Webcomic/MidnightSleuth'' trilogy is that it takes place in an alternate universe where [[QuirkyMinibossSquad the Midnight Crew]] and [[HardboiledDetective Team Sleuth]] have swapped roles.

154[[folder:Film -- Animated]]
155* ''WesternAnimation/JusticeLeagueCrisisOnTwoEarths'', strongly inspired by the Crime Syndicate stories above.
156** ''WesternAnimation/JusticeLeagueCrisisOnTwoEarths'' depiction of Batman's counterpart Owlman is far more representative of an "evil version" than the Justice Lords Batman. Owlman sums up the entire topic of alternate versions nicely to Superwoman (evil version of Mary Marvel, counterpart to Wonder Woman):
157--->'''Owlman:''' Every decision we make is meaningless because somewhere, on a parallel Earth, we have already made the opposite choice. We're nothing. Less than nothing.\
158'''Superwoman:''' How can you say that? We're rich. We're conquerors.\
159'''Owlman:''' ''[pointing at alternate Earths]'' And here we're poor. We're slaves. And here, our parents never met, so we were never born. Here, the world ended in nuclear war. Here, no fish was brave enough to crawl up on land and humans never evolved. And so on, ad infinitum.
160** And summed it up even more succinctly to Batman later on:
161--->'''Batman:''' YoureInsane.\
162'''Owlman:''' Does it really matter? There are alternate versions of me that you would find quite charming.
163* In ''WesternAnimation/SpiderManAcrossTheSpiderVerse'', [[spoiler:Earth-42 functioned as one to Miles' home universe of Earth-1610B. Because of the BigBad, the spider that was supposed to give Earth-42 Miles his powers ended up going to our Miles, leaving that reality without a ComicBook/SpiderMan. As a result, he became an EvilDoppelganger to Miles after his father died, becoming his reality's Prowler]].
164[[/folder]]
165
166[[folder:Film -- Live Action]]
167* In ''Journey to the Far Side of the Sun'' (1969) by Creator/GerryAnderson and Creator/SylviaAnderson, the astronauts are sent to inspect the planet that is orbiting directly on the other side of the sun from us. But a malfunction when they arrive brings them home Except that everything is mirrored. Writing. Body parts. It turns out the other planet sent the mirrored astronauts off to our Earth at exactly the same time.
168[[/folder]]

170[[folder:Literature]]
171* In Creator/AndreNorton's ''Star Gate'' (1958), the human colonists of Gorth, seeking an AlternateUniverse version of their beloved adopted planet that has no native intelligent life, accidentally stumble into a version in which their own counterparts have used their advanced technology to enslave the inhabitants.
172* The Literature/DarkReflectionsTrilogy features a literal mirror universe.
173* Characters from Mirror Universe settings occasionally turn up in the {{Literature/Nightside}} novels, such as Dark Artur (an alternate King Arthur whose mentor Merlin had sided with the Devil), or Joan Taylor and Steven Shooter (GenderFlip villainous versions of the series leads).
174* Spider Robinson's story "Mirror/rorriM Off the Wall" has an invasion by Trebor, the evil mirror twin of Robert, a patron of Literature/CallahansCrosstimeSaloon. [[spoiler: One of the tipoff's is that Callahan's bar doesn't ''have'' a mirror normally, just quotes written behind the bar, and suddenly, there is a mirror.]]
175* ''Literature/{{The Mirage}}'' is a novel about a Mirror Universe UsefulNotes/TheWarOnTerror, where a liberated, cosmopolitan United Arab States is attacked by a fundamentalist Christian America and ends up invading them in retaliation. Of course, the fact that it's such a funhouse mirror version of our world is key to the plot...
176* ''Literature/TheLastDragonChronicles'': Every main character in ''Fire World'' has a counterpart on Earth. It's also {{Lampshaded}} in-universe.
177** David is ...well, David.
178** Eliza is [[spoiler: Elizabeth]].
179** Harlan is [[spoiler: Arthur]].
180** Penny is [[spoiler: Lucy]].
181** Rosa is [[spoiler: Zanna]].
182** Gwyneth is [[spoiler: Gwillana]].
183** Mr. Henry is [[spoiler: Mr. Bacon]].
184** Mathew is [[spoiler: Tam]].
185** Angel is [[spoiler: Alexa]].
186** Boon is [[spoiler: Bonnington]].
187** Stromberg is [[spoiler: Bergstrom]].
188* The "Cosmic Chess Match" arc in ''Literature/PerryRhodan'' is famous for the protagonists ending up in one of these after an experiment gone wrong. In this case, it's not entirely clear whether it was a fully "legitimate" instance of the trope or an artificial creation of one of the dueling [[SufficientlyAdvancedAlien super-intelligences]]; the trigger condition for returning home ([[spoiler:Perry Rhodan himself killing his own evil double]]) and the fact that it worked basically instantly once met seem to rather hint at the latter, but [=ANTI-IT=] could have just as easily made use of an already-existing alternate universe.
189* ''Literature/{{Defection}}'': is a setting where travel between dimensions is relatively common, albeit only truly available to those on the larger end of the power pool, thus resulting in a lot of alternate versions of the same person.
190* Trey and Troy, the "bad" Dimensional Guardians from the web fiction serial ''Literature/DimensionHeroes'' often pick fights with the protagonists.
191* In the eighth ''Literature/CaptainUnderpants'' book, George and Harold accidentally travel to a parallel universe where all the people they know are the opposite of how they are in the main universe: InsufferableGenius Melvin is a drooling idiot, George and Harold themselves are evil, and all the teachers are nice and helpful. When they try to escape, their {{Evil Doppelganger}}s and evil Captain Underpants tag along and wreak havoc in their world.
192[[/folder]]
193
194[[folder:Live-Action TV]]
195* In the ''Series/DoctorWho'' story "[[Recap/DoctorWhoS7E4Inferno Inferno]]", the Doctor is transported to a world where Britain is a military dictatorship and the UNIT characters are either evil (like Brigade Leader Lethbridge-Stewart and his EyepatchOfPower and Platoon Underleader Benton) or resignedly following orders (like Section Leader Liz Shaw and Doctor Petra Williams)[[note]]as the ''Franchise/StarTrek'' example was not yet so dominant, the evil universe versions of both the Brig and Stahlman have less facial hair than the mainstream ones[[/note]]. The location and plot are the same (an attempt to drill into the Earth's mantle), but [[spoiler:penetration is reached, and the world is destroyed. The Doctor is able to escape in time and stop his Earth's version of the project]].
196* Subverted in the ''Series/StargateSG1'' episode "[[Recap/StargateSG1S9E13RippleEffect Ripple Effect]]". A whole shipload of alternate SG-1 teams from various universes arrives. One team ends up hijacking the ''Prometheus''. Mitchell says to his double, "You don't have beards, so I know you're not from the Evil Twin Universe". It turns out that this particular team [[spoiler:comes from a universe in which Earth does not have a working Zero Point Energy module and needs one to power their defenses. So out of desperation, they've contrived the conditions that caused the dimensional travel so they can steal someone else's. You'd think they'd just get all the Samanthas to work on the problem. Which is pretty much how they solve the problem of sending everyone back.]]
197** In the Alternate Universe of "[[Recap/StargateSG1S3E6PointOfView Point of View]]", Apophis has a goatee, a la Spock, but everyone is morally the same, except maybe Teal'c (our Teal'c didn't give him a chance to talk before offing him).
198* ''Series/Charmed1998'' had a Polar Opposite World in the two-part finale of Season 6, where good and evil were reversed. Mortal people and places were all grungier, the Charmed Ones were evil witches, demons were good (such as Barbas being the Demon of Hope instead of the Demon of Fear), and the Underworld was green and pleasant. Leo was a Darklighter instead of a [[GuardianAngel Whitelighter]], and Paige and Chris were Darklighter-witch crossbreeds instead of Whitelighter-witch crossbreeds. Presumably the Darklighters ([[EvilCounterpart Evil Counterparts]] to Whitelighters who try to eliminate them with specially poisoned crossbows) of the primary universe were Whitelighters in the Mirror Universe. The characters had to forge an alliance with their "evil" selves to get both worlds back into balance after some of them swapped places.
199** An imbalance that occurred when these universes crossed caused a total {{Flanderization}} of their respective moralities for the second part of the two-parter; in our 'good' universe, even the most minor of infringements of law or courtesy was now enough to have you (cheerfully) shot, whereas so much as the slightest gesture of kindness in the Mirror Universe would now incur the same consequence. Also, it was always day in the good world, and always night in the evil one. [[EvenEvilHasStandards Neither set of Charmed Ones found this situation tolerable]], and they managed to undo it by the end of the finale.
200* Parodied in a "lost episode" of ''Series/MyNameIsEarl'', which retells the story of the {{Pilot}}, except instead of watching Carson Daly, Earl flips over to ''WesternAnimation/FamilyGuy'' and is inspired by Stewie Griffin to take revenge on everyone he feels has wronged him. He is eventually killed after failing to take revenge on his old bullying victim Kenny for making him "feel stupid".
201* In an episode of ''Series/PowerRangersNinjaStorm'', Tori is sent into a parallel universe where the other Rangers are the bad guys and the villains are good guys (the shallow, fashioned obsessed villainesses are even hippies in this universe).
202* One of the many, many sphere malfunctions in ''Series/SevenDays1998'', rather than sending Parker into a Mirror Universe, actually inverted the ''real'' universe (since the existence of parallel universes was disallowed by the show's AppliedPhlebotinum), changing Never Never Land into the seat of a tyrannical dictatorship, Ramsey into a spaced-out hippie, and reversing all writing. Parker, being morally ambiguous to begin with, was immune. Also, everything in this "inverted universe" is mirrored. Get it?
203* ''Series/TheMiddleman'': In "The Palindrome Reversal Palindrome", the alternate-universe Middleman goes from all-American Boy Scout type to less-than-altruistic AntiHero, Pip goes from selfish brat to Catholic priest working to help the helpless, Lacey is a stripper, with Noser as her muscle, the entire world is a {{dystopia}} ruled by Fatboy Industries, and ''[[spoiler: Wendy]]'' is the BigBad. Oh, and all the male characters have beards.
204* ''Series/MysteryScienceTheater3000'' explicitly parodies the ''Star Trek'' mirror universe in their "[[Recap/MysteryScienceTheater3000S06E11LastOfTheWildHorses Last of the Wild Horses]]" episode. Tom and Gypsy are swapped with their evil counterparts. In the evil universe, Dr. Forrester and TV's Frank are trapped on the SOL, while bearded Mike and the bots subject them to horrible movies. Notice how they even sit on opposite sides of the theater.
205* ''Series/HerculesTheLegendaryJourneys'' had a universe where Herc was an evil ruler called the Sovereign, Iolaus was his jester, Xena was a conniving minx, and Gabrielle was a vicious executioner. Opposing the Sovereign's rule were such figures as Joxer (the Spock "one good man" type character, but "opposite" to "our" Joxer by being competent) and Ares, god of love. Aphrodite was also the prim and proper queen of the gods; Hera is said to be the goddess of music, while Cupid is mentioned being the god of war. Later episodes referred to Callisto as a virgin priestess, and Cheiron as a SadistTeacher.
206** The Sovereign also had a BeardOfEvil. Unfortunately for him, he doesn't realize that the main universe's Ares is also evil and has no qualms about killing.
207** In the first episode to feature this universe, a rule was established where everyone was connected to their counterpart. If one person on either world died for whatever reason, their counterpart would immediately die along with them. A loophole was later established in that a character being in the Netherworld (an in-between realm) negated that connection; that's how Hercules survives Ares killing the Sovereign.
208** Notably, in Season 5, the court jester Iolaus crossed over to the main universe permanently and became more developed. This was during a period where the regular Iolaus was dead long-term, so production made use of Michael Hurst by bringing back the jester counterpart.
209* ''Series/KamenRiderDragonKnight'' uses this concept literally - the parallel world of Ventara is connected to Earth through reflective surfaces like mirrors and windows. The Earth Kamen Riders are mirror twins of the original Ventaran Riders, who are all heroes, which causes some interesting moments. For example, the good guys are a bit weirded out by Ventaran!Strike, since his Earthly counterpart is a SmugSnake {{Jerkass}}. [[spoiler:He ends up in a relationship with a reporter at the end of the series.]]
210* Kevin, Gene, Feldman and Fargas in ''The Bizarro Jerry'' episode of ''Series/{{Seinfeld}}''.
211* Not played straight, but homaged in ''Series/{{Fringe}},'' where practically the first person encountered in the alternate universe is played by Creator/LeonardNimoy. In the show's "over there" universe Walternate is a villain in the WellIntentionedExtremist mode, although the original Walter has some ethically suspect things in his past too. Their version of Olivia is essentially good but does bad things because she believes in Walternate. Other characters aren't better or worse, just different. And a few characters change alignment after the CosmicRetcon.
212** Interestingly, there is one prominent alternate universe character who did not have a counterpart in "our" universe for the longest time. Finally, a "good" version (who looks a little nerdy in glasses) shows up... for a single episode. He returns as a regular in the following season.
213** In a more straight version of this trope, there's a season 4 episode where the Fringe Divisions from both universes are working together to catch a serial killer in the alt-universe, with the help of his counterpart from the prime-universe, who thanks to a woman he met in his childhood, becomes able to contain his psychotic urges and avoid the crime path, such luck his alternate did not have.
214* In the ''Series/BuffyTheVampireSlayer'' episode "[[Recap/BuffyTheVampireSlayerS3E9TheWish The Wish]]", Cordelia [[BeCarefulWhatYouWishFor gets her wish that Buffy never came to Sunnydale]], turning the town (and likely the world) into hell. Xander and Willow are vampires and rule the streets at night, Angel is regularly sexually tortured by Willow, Buffy eventually turns up bitchier than [[Franchise/{{Terminator}} Sarah Connor at her worst]] to stop a vampire plot to industralize the killing of humans, only to die trying like most of the show's characters.
215* In season two of the GameShow ''Series/WhereInTimeIsCarmenSandiego'', this was common type of skit. In the Mirror Universe, AMCE was a force of evil and VILE was a force of good. Kevin {{lampshaded}} this when one of the skits came up.
216* ''Series/{{Pixelface}}'': In one episode, Riley exits the game from the wrong port and finds himself in a different console where Alexia is an ExtremeDoormat, Aethelwynee is a JerkJock, Rex is an InsufferableGenius, Claireparker is ThePigpen and Kiki is... a large, hairy man.
217* ''Series/LostInSpace'' did an episode entitled "The Anti-Matter Man" where John Robinson gets kidnapped by his mirror self, who wants to take his place in the "normal" world. In the mirror world, everything is different, where [[spoiler: because the robot is good, his mirror counterpart is permanently imprisoned]]. Oddly enough (since it was slightly earlier) [[spoiler: Drun (the mirror Don West) has a [[Franchise/StarTrek beard]]]]. Will, Dr. Smith and the Robot rescue him, and the episode concludes with [[spoiler: John throwing Mirror John over the side of the "bridge" between the normal world and the mirror world]].
218* ''Series/TheSuiteLifeOfZackAndCody'': Zack and Cody travel to an alternate universe in the episode "Suite Life of Success" where everything is ideal for them: Mr. Moseby is a fun-loving rule-breaking cool guy; the hotel is called "The Fitzpatrick" because Maddie is the heiress instead of London; London has Maddie's former job as candy counter girl and is the smart one while Maddie is TheDitz; Carey is a famous singer and lets the boys do everything they want; Esteban is a maid; George Clooney is on the nickel; and Arwin is Carey's manager has hair wears leather and Carey has a massive crush on him instead of vice versa.
219* Parodied in ''Series/{{Community}}''. When the tossing of a die to choose who picks up some pizza creates seven alternate universes, one horrible one is created where [[spoiler: Pierce dies, Jeff loses an arm, Shirley becomes an alcoholic, Annie suffers a mental breakdown, Troy's larynx is destroyed, and Britta dyes a blue streak in her hair]]. GenreSavvy Abed deduces that they're in the "evil" universe, makes them all [[Franchise/StarTrek fake beards]], and makes it their job to break into the true universe and wreak havoc.
220* Polish sitcom ''Swiat wedlug Kiepskich'' has an episode where the son of the titular dysfunctional family passes by the mirror in the hall and discovers that his reflection is wearing glasses, formal suit, and a rather nerdy haircut. After brief argument with the reflection, he finally responds with a headbutt which results in them both swapping places with each other and he ends up in an alternate universe where his family is rich, their alcoholic neighbours are tennis-playing scholars with academic degrees, and he's a world-famous fiddle player. Who is about to have his biggest performance in just a few hours. HilarityEnsues.
221* ''Series/WizardsOfWaverlyPlace'' has this in the episode "All About You-niverse".
222* ''Series/FlandersCompany'' does this with the {{Villain Protagonist}}s discovering an alternate universe where their company trains and forms superheroes instead of supervillains.
223* Here's an example you might not expect: in a "The Word" segment on ''Series/TheColbertReport'' from February 10, 2007, Stephen opens with reporting on a new theory about parallel universes. In the middle of the segment, there is suddenly a cheesy science fiction zoom-out, and suddenly Stephen is a left-wing hippie whose "Word" was "Troops Out Now!" After a while of seeing Hippie!Stephen's reporting, the same zoom-out is shown, and you cut to "real-life" Stephen arguing in character that the US military should invade any parallel universes we find.
224* The alternate Enchanted Forest created by the book ''Heroes and Villains'' in the Season 4 finale of ''Series/OnceUponATime'' has shades of this. Snow White is the Evil Queen, with Charming as the Huntsman and the Dwarfs as her royal guard. Meanwhile, Regina is in Snow's role as the bow-wielding freedom fighter, and Rumpelstiltskin is a noble and brave WhiteMagic user known as the Ogreslayer and the Light One. Other characters seem to have less of a personality shift, although their position in the story has changed. This is all the result of Rumple's desires coupled with the whims of the current Author, Isaac, who has a thing against Snow and Charming and thinks villains are more interesting to write.
225* Happens in the ''Series/HenryDanger'' episode "Opposite Universe" when Henry and Charlotte end up in a Mirror universe while their evil counterparts are trapped in the other, "good" universe after a tubing into the Man Cave during an electrical storm. Obligatory [[BeardOfEvil evil beards]] for Captain Man, Schwoz (kind of), and Mr Hart. Piper is a non-violent, unselfish girl.
226* While not played perfectly straight in ''Series/TheFlash2014,'' we get a lot of morality inversions in Earth-2. Most of the CCPD are still good guys though their circumstances are different, but when it comes to the superpowered players:
227** Our Hunter Zolomon is a normal guy as far as we can tell. Theirs is [[spoiler:the BigBad Zoom]].
228** Our Caitlin is a friendly scientist. Theirs is the gleefully sadistic and murderous Killer Frost.
229** Our Cisco is also a friendly scientist. Theirs is TheDragon.
230** Our Ronnie Raymond: half of the heroic Firestorm, until his apparent death. Theirs: ''all'' of the evil Deathstorm after having wrested full control away from Martin Stein, who remains [[AndIMustScream trapped inside him, unable to even communicate by now.]] (Which may make Stein a rare person, like Barry, Iris, and Joe, to be good in both worlds.)
231** Our Floyd Lawton is the assassin Deadshot, with perfect aim to the point of it being a superpower. Theirs is a police officer, who is called Deadshot by those who make fun of his ''terrible'' aim.
232** Our Laurel Lance, or should we say Dinah Laurel Lance, is the second Black Canary. Theirs is the evil Black Siren, although she has since made a HeelFaceTurn.
233** Our Harrison Wells was shady where the viewer could see but the cast couldn't, eventually revealed as [[spoiler: Eobard "Reverse-Flash" Thawne.]] You worry when theirs turns out to be a bit shady too, but it turns out that he's [[spoiler: trying to protect his daughter, held by Zoom, at any cost]], and eventually levels with the team. Of course, this isn't a perfect example since [[spoiler: Reverse-Flash had taken the identity of the true Wells of our world, who seems to have been a decent guy]].
234** Our Linda Park is an innocent reporter. Theirs is the enemy known as Dr. Light. She's more sympathetic than most of Zoom's crew, though.
235** Our Henry Hewitt: The villain Tokamak, who blasts away at the heroes with nuclear blasts even after the thing he was supposedly mad about no longer mattered. Theirs: Innocent member of Star Labs.
236** While the Green Arrow is still good, we get a different sort of flip: his origin story happened much the same except it was Oliver who died and Robert who survived to become the hero.
237** Not ''all'' of the CCPD is the same. Our David Singh is the police captain. Theirs is a criminal who was being brought in, though it was a brief enough sequence that we don't know how villainous or redeemable he is.
238** Our [[spoiler:Adrian Chase]] is the villain Prometheus. Theirs is the Green Arrow after Robert Queen.
239** Our Tommy Merlyn is a decent guy and a doctor. Theirsā€¦ is also decent but is also [[spoiler:the Dark Archer who seeks to do what his father tried to do on Earth 1]].
240** There's also Earth-X, where many heroes and other good characters are honest-to-God Nazis. This includes Oliver (Black Arrow and the ''Fuhrer''), Kara (Overgirl and Oliver's wife), Barry (Blitzkrieg), [[spoiler:Tommy Merlyn]] (Prometheus), Quentin (a Sturmbannfuhrer who had his own bisexual daughter Sara executed), Laurel (Siren-X, who is even worse than Black Siren).
241* ''Series/{{NTSFSDSUV}}'': Trent accidentally comes into contact with a MagicalParticleAccelerator and travels to an alternate dimension where the NTSF is a terrorist organization rather than a crime-fighting unit.
242* ''Series/TheTwilightZone1959'': In "[[Recap/TheTwilightZone1959S1E21MirrorImage Mirror Image]]", Millicent Barnes speculates that the appearance of her {{Doppelganger}} at the bus terminal is due to the normal universe converging with an alternate universe and that her doppelgƤnger must eliminate her in order to remain in the normal universe. Paul Grinstead later learns that she is right.
243* ''Series/DarkMatter2015'': An alternate universe is introduced in the second season episode "Stuff to Steal, People to Kill". It's not a straight example of a Mirror Universe because not everyone's moralities are reversed, but the moralities of the ''Raza'' crew (our protagonists) are. In the primary universe, they were mindwiped at the beginning of the series and became subject to AmnesiacsAreInnocent, and in the alternate universe this never happened, so they are still a bunch of mass-murdering [[PsychoForHire Psychos for Hire]]. The AU crew escape into the main universe at the end of the episode, and join forces with Ferrous Corp and Emperor Ishida as a BigBadEnsemble in Season 3. The ChronicBackstabbingDisorder that crewmembers Two and Three encounter while ImpersonatingTheEvilTwin on the alternate ''Raza'' is an intentional ShoutOut to the attempted coup Kirk, [=McCoy=] and Uhura face in the ''Star Trek'' Mirror Universe. In keeping with the ''Trek'' Mirror universe episodes, the alternate ''Raza'' is also more dimly lit.
244* As a show about parallel universes as the central premise, logically there will be many episodes of ''Series/{{Sliders}}'' with variants of the main characters who are evil or at least very morally questionable. Most notably however can be considered the introduction of Logan who is Quinn Mallory's [[spoiler:double, as the difference between being born a man or woman is just a chromosome]]. She was intended as a recurring villain but was vetoed by the studio. Another is the infamous "Evil Arturo" seen in the episode "Post Traumatic Slide Syndrome" which fans debate to this date whether he remained in that world or slid with the rest. Arturo is evil in several episodes tho. Rembrandt and Wade also have their share of evil or at least murkier versions.
245* ''Series/TheUmbrellaAcademy2019'': TheStinger for Season 2 has [[spoiler: the Red Sparrow Academy siblings as the AlternateTimeline bad counterparts for the Umbrella Academy siblings. The alternative universe Ben in particular is [[{{Jerkass}} mean and rude]] unlike the AllLovingHero and FriendlyGhost Ben of the original timeline who performed a HeroicSacrifice]].
246* ''Series/RedDwarf'' introduced an interesting variation in the episode "[[Recap/RedDwarfSeasonIIIBackwards Backwards]]". The crew travels to an alternate universe where time runs backwards, which results in Rimmer and Kryten deciding that they wanted to stay since objectively this world is better since death doesn't exist due to people coming back to life before aging backwards and criminals un-commit crimes. They further point out that in this universe Hitler will, in a few decades, be responsible for bringing thousands of people back to life and liberating countries from an oppressive government that he then dismantles, while Lister responds that the story of Santa Claus is about a fat man who steals all the kid's favourite toys.
247* ''Series/{{Smallville}}'' had a couple of Evil Twin variants.
248** There's also Clark Luthor/Ultraman, an AlternateUniverse version of Clark who was raised by Lionel Luthor. To say he's an utter [[TheSociopath psychopath]] would be an understatement. Lois, Tess, and Oliver all immediately realize that this isn't their Clark and proceed to deal with him accordingly.
249*** Technically the Earth-2 Lionel is this to E-1 Lionel. E-1 Lionel died while on the [[HeelFaceRevolvingDoor Face]] side, and while he's not exactly [[MagnificentBastard a nice guy]], he's still ''far'' from TheSocialDarwinist AxCrazy E-2 Lionel.
250* One episode of ''Series/TheTwilightZone1985'' featured one where neither side was evil, simply different. It centered around an unappreciated inventor who discovers an alternate reality where his counterpart is a famous tycoon beloved for his revolutionary creations. Since the inventor wants recognition and the tycoon hates his fame and wants anonymity, they both switch places and wind up being much happier for it.
251[[/folder]]
252
253[[folder:Music]]
254* K-pop group [[Music/GirlsGeneration Girls Generation]] also known as SNSD played this one straight in their story version music video for Oh! and Run Devil Run. An accidental spill causes their computer to open a door allowing [[JapaneseDelinquents Delinquent]] versions of the girls to step into the clubhouse where they proceed to trash the place. One of the girls unplugging the computer causes the evil versions to fade away like static.
255[[/folder]]
256
257[[folder:Mythology and Religion]]
258* Some would say [[Myth/NorseMythology the myth of Thor]] in Outgard (Thor:[=OutgardLoki=], Loki:Logi, Thjalfi:Hugi).
259[[/folder]]
260
261[[folder:Newspaper Comics]]
262* In 2015 ''ComicStrip/DickTracy'' launched into an arc where Sam "Trigger" Catchem and Pat Patton are goons working for "Boss" Tracy, 88 Keyes is a [[spoiler: short-lived but]] honest nightclub owner, and Pruneface is the chief of police. This alt-universe is eventually [[spoiler:[[ShowWithinAShow revealed as a movie set]]]].
263[[/folder]]
264
265[[folder:Podcasts]]
266* ''Podcast/{{Hello From the Magic Tavern}}'' quite naturally has a mirror universe in which Arnie, Chunt, and Usidore are all evil, and work with the {{Dark Lord}} to conquer Foon, and Tannikin the Terrible is a heavily-{{tattooed| crook}} psychopathic mass murderer (but still adorable). Blemish, naturally, is heroic (but still a jerk to evil people). Curiously, the Dark Lord appears to be a constant, and there are some other differences, such as the wizards all being associated with different colours. The version of Arnie in this universe comes from a mirror Earth in which he actually did abandon his wife and child, and fell through a portal behind a Chick-Fil-A in Evil Chicago (yes, that's the city's actual name).
267[[/folder]]
268
269[[folder:Tabletop Games]]
270* In the HERO game ''TabletopGame/{{Champions}}'', a supplement describing various one-off AlternateUniverse concepts included a mirror universe, complete with ThePsychoRangers versions of the Champion superhero team.
271* As a direct homage to DC's Crime Syndicate, the TabletopGame/FreedomCity setting for ''TabletopGame/MutantsAndMasterminds'' has a Mirror Universe (Anti-Earth) in which the city is called Empire City and the Freedom League is replaced by the Tyranny Syndicate.
272* The fan-made ''WebOriginal/Brighthammer40000'' campaign setting for the ''TabletopGame/Warhammer40000'' roleplaying games is largely a Mirror Universe, with some BizarroUniverse mixed in -- given [[CrapsackWorld the state of the normal universe]], it's a [[LighterAndSofter pretty nice place to live]]. There are exceptions, however. The Tau are ''exactly the same'' -- their new status as villains is simply because the rest of the universe now looks better, rather than worse, by comparison. The Tyranids are also the same -- they're mirrored in that they're now the threat another extragalactic faction is fleeing from, rather than being implied to be fleeing from an even worse extragalactic faction. While the Eldar are reversed in alignment as well, the makers took it to a logical conclusion: The Bright (Dark) Eldar were born in dire straits, and are fighting a losing war against their cruel brethren. The Slaan are a borderline exception, as well: They're much the same, but they're now villains as the setting replaces the mysterious-but-benevolent [[{{Precursors}} Old Ones]] of ''40k'' and ''TabletopGame/WarhammerFantasy'' with the twisted and horrifying Great Old Ones; being devoted servants to the Old Ones is now an unequivocally bad thing. The Deceiver (the worst of the extremely nasty C'Tan in {{Canon}}) is still completely evil, it's just that how he goes about it is reversed -- he's known as the Soothsayer, and rather than causing trouble with deception, he instead specializes in sharing dangerous and unpleasant truths and dispelling even harmless or necessary lies. The other C'Tan play this straight, though -- the Daybringer is flat-out benevolent, the Void Dragon is well-meaning but utterly alien and unaware of just how dangerous his knowledge can be in the wrong hands, and the Outsider is in a self-imposed exile due to emotional and mental scars from battling the Great Old Ones... but the Tyranids are heading toward his "prison" and ''no-one'' knows how that will turn out.
273** As listed in the Fan Works section above, inversions of the Literature/HorusHeresy are rather common among ''TabletopGame/Warhamemer40000'' fans.
274[[/folder]]
275
276[[folder:Toys]]
277* ''Toys/{{Bionicle}}'' has two. The "Melding Universe" is a world where the Great Beings managed to fix Spherus Magna before it blew up, Toa look like Matoran (and vice versa), and the regular universe's {{Big Bad}}s (the Makuta) embraced light rather than darkness. The "Dark Mirror Universe" is a world where the Toa became [[KnightTemplar Knights Templar]] and conquered the world as a result of Toa Tuyet successfully obtaining the Nui Stone and becoming an unstoppable tyrant with her enhanced power. The Makuta, the [[BountyHunter Dark Hunters]], and a rag-tag group of renegade Toa form the resistance. It isn't a perfect example though, as most characters still have the same personality as the main universe. Takua also never became the Toa of Light in this universe because he was unneeded due to the Makuta not being the threat they were in the main universe.
278[[/folder]]
279
280[[folder:Video Games]]
281* ''VideoGame/CityOfHeroes'' has the "Praetorians", evil world-conquering versions of the "normal" world's main heroes. Of course, it's up to the player character(s) to defeat them and ensure that they don't extend their conquests to other worlds.
282** They have a Greek name, and Tyrant wears Greek-style armor, because of a legendary RealLife incident: when told of the existence of [[AlternateUniverse alternate universes]], Alexander the Great wept: "So many worlds, and we have not yet conquered one."
283*** Also as a foil to the heroic Freedom Phalanx.
284** The expansion ''Going Rogue'' (not to be confused with UsefulNotes/SarahPalin's book) looks to be giving them a {{Retcon}} into more 'Justice Lords' than 'Crime Syndicate', where incidentally there is also a [[TheSyndicate Syndicate]] in Praetorian Earth. There's also good versions of several villain groups; the [[CircusOfFear soul-stealing Carnival of Shadows]] are the heroic Carnival of Light, and [[LaResistance the Resistance]] seem to be based on [[CyberPunk the Freakshow]].
285** Other confirmed "opposites" include:
286*** Counterpart to Clockwork King [[spoiler: is Metronome, who is a disembodied psychic entity.]]
287*** Counterpart to Ghost Widow, [[spoiler: is Belladona, who is still alive and a member of the Resistance.]]
288*** Counterpart to Nemesis, ''the'' MagnificentBastard, is an apparent nobody
289*** Counterpart to Odysseus, leader of the Warriors, is a trainer in the Underground.
290*** Counterpart to Calvin Scott, husband to Aurora Borealis, is the leader of the Resistance.
291*** Counterpart to Venessa [=DeVore=], leader of the Carnival of Shadows, is the leader of the Carnival of Light and is responsible for the Resistance's very existence. She saw the Emperor's new order coming and banded together several military leaders to stand against him. Her [[PsychicPowers psychic abilities]] also keep Mother Mayhem and the Seers from finding the Resistance.
292** And the [[{{Fanon}} fans love to embrace this]], creating Praetorian counterparts of their own characters, and of currently unseen canon characters.
293** The same game featured the "Amerika Korps", who were from an AlternateHistory where, you guessed it, Hitler conquered and occupied the US. Clumsily [[RetCon Ret Conned]] into the Council Empire later on, though Issue 15 brings back the most memorable character of the Amerika Korps.
294*** The "Amerika Korps" could be seen as a slight subversion to the idea that they were identical mirror counterparts. While the game's background clearly stated that [[TheCape the Statesman]] and [[EvilCounterpart the Reichsman]] could spend all day slamming each other into the concrete, the Reichsman did not like competitors approaching his power level and deliberately made sure his "teammates'" training were less than adequate. That came back to bite him in the ass.
295* ''VideoGame/ChampionsOnline'' has Multifaria, which features in the "Resistance" Adventure Pack. Here, Millennium City has become New Harmon, the seat of an evil dictatorship run by "Citizen Harmon", this world's version of the heroic Defender, who is better known as [[spoiler:Shadow Destroyer]]. The evil Champions are known as the Conquerors, and many of the Champions (Kinetik, Witchcraft, etc.) have evil counterparts to be fought in this world, while you aid good versions of several of your villainous enemies in the normal world [[spoiler:along with the original Doctor Destroyer, who Shadow Destroyer defeated and imprisoned when he came to Multifaria before stealing his Destroids for his own use]].
296* ''VideoGame/KirbyAndTheAmazingMirror''. However, it's similar to most of its predecessors, aside from the sidekick Kirbies that wander around.
297** PlayedWith in that Mirror World Kirby [[spoiler:isn't evil, he just thinks that Kirby is ''his'' evil counterpart]]. However, [[AntiHero Meta Knight's]] Mirror World counterpart plays this trope perfectly straight, lacking Meta Knight's sense of honor. The BigBad of the game, [[spoiler:Dark Mind, aka, the Mirror World's equivalent to [[VideoGame/KirbysDreamland3 0]]]], is as cruel, if not, crueler than than their real counterpart.
298** If ''VideoGame/KirbyTripleDeluxe'' is anything to go by, [[spoiler:King Dedede's Mirror World counterpart also plays this straight, being more maliciously evil than the merely greedy Dedede]].
299* The "Shadow Mirror" world that features prominently in ''VideoGame/SuperRobotWarsAdvance'' and ''VideoGame/SuperRobotWarsOriginalGeneration''. May or may not be the world that ''[[VideoGame/SuperRobotWars64 SRW 64]]'' took place in.
300** Shadow Mirror isn't a one-for-one Mirror Universe, though -- while some characters are flipped (most prominently [[VideoGame/SuperRobotWarsCompact2 Kyosuke Nambu/Beowulf]]), others were mostly the same or didn't even last that long (Ryusei Date was apparently the same up until Beowulf killed him, and Rai Fujiwara was killed test-piloting the original [[SuperPrototype Huckebein]]). In ''Advance'', it's stated that Shadow Mirror's [[Franchise/{{Gundam}} Amuro Ray]] died young, paralleling the ''Anime/MobileSuitGundam'' novel rather than the anime.
301** There's also [[spoiler:Lemon Browning, who is the AlternateUniverse version of heroine Excellen Browning. The split came in a shuttle crash; the original Excellen survived without a scratch, while the other died and was [[ReplacementGoldfish rebuilt by her parents]] into a cyborg.]]
302** Then there is Asakim Dowin from ''VideoGame/SuperRobotWarsZ'', who is clearly an EvilTwin, or at least an EvilCounterpart, to Masaki Andoh from ''VideoGame/SuperRobotWarsOriginalGeneration'', being his antithesis in every possible way and having a mecha that is basically a darker version of Masaki's Cybuster. Many fans speculate that just like how Masaki's {{backstory}} involves the mystical world of La Gias, Asakim's might just involve La Gias' Mirror Universe too.
303* The ''VideoGame/AdventureQuestWorlds'' 2nd Birthday Event has your hero visiting the Mirror Realm, where pretty much everything is switched around. Battleon is called Battleoff, Aria owns a butcher shop instead of a pet shop, Yulgar's Inn is called "Ye Olde Outt," Zorbak is actually good, [[{{Cloudcuckoolander}} Cysero]] is actually sane, Warlic is a MadScientist rather than a mage, and the greatest hero of this reality turns out to be [[BigBad Drakath]]. His "Lords of Order" (basically good mirror counterparts of the Chaos Lords you've fought so far) have been captured by this realm's BigBad, King Alteon, who commands an undead army led by Artix, who is an undead Doom Paladin in the Mirror Realm, and you have to free them. The adventures include a trip to Lightovia (basically a mirror Darkovia) where Safiria is the Queen of the Werewolves instead of the Vampires (and where the werewolves love silver rather than it being the bane of their existence), a trip to a farm where a farmer is infecting his chickens with Chaos (don't ask) and finally heading to Alteon's secret lair, an evil mirror version of Swordhaven Castle, to do battle with undead Artix.
304* Many team vs. team combat games and multiplayer RTS/turn-based strategy games implicitly use this for the sake of fairness; both teams will have access to identical characters who fight in levels that are the same on each team's side. [[ColorCodedForYourConvenience Color-coding]] or something else that doesn't affect gameplay distinguishes the two "worlds."
305* ''VideoGame/SuperPaperMario'' has the twin cities of Flipside and Flopside, which are actually connected to each other through a mirror. Flipside is the game's HubLevel with a white tower leading to seven colorful worlds, while Flopside is its dark counterpart which looks like a mirrored version of Flipside with dilapidated buildings and an Ominous Black Tower leading to TheVeryDefinitelyFinalDungeon. The Ancients constructed the two cities to be opposites of each other because light can't exist without darkness. The inhabitants of Flopside are not evil, but do have opposite personalities from their counterparts and also have different skin colors and triangular noses instead of square noses. Most residents of the two cities are unaware that the other city exists, although one pair of counterparts decide to switch places with each other after they contact each other in their dreams.
306* ''VideoGame/SomaSpirits'': There is a Joy and a Sorrow version of everyone, and everywhere. One version of someone getting too emotional can affect the other.
307* ''VideoGame/CallOfDutyZombies'' has an inversion with the Primis crew (that acts as the current protagonists) acting as the good counterpart (from an alternate universe) to Ultimis, the original recurring team of Black Ops 1. Whereas the Ultimis team is made up of [[SociopathicSoldier battle-crazed soldiers]] that embody negative stereotypes of their respective countries (insane drunken [[VodkaDrunkenski Nikolai]], gun-obsessed [[ShootEverythingThatMoves Tank]], etc.), Primis comes from an alternate universe where the 4 met under different circumstances at a younger age, and embody positive stereotypes of their respective countries (determined comradery for [[ChummyCommies Nikolai]], patriotic hero for [[EagleLand Tank]], etc.). Most notable is Richtofen--instead of being the ObviouslyEvil HerrDoktor, Primis Richtofen is an AntiHero who does what he does [[IDidWhatIHadToDo "To secure a better tomorrow"]]
308* ''VideoGame/CrashBandicoot'' has the obviously titled Evil/Nega Crash, his alternate universe equivalent from the Tenth Dimension. Fake Crash (a goofy lookalike created from "an experiment gone horribly wrong") interchanges between being an antagonist or occasional friend of Crash, similar to Wario.
309* The Mirror of Mystery bonus level in ''[[VideoGame/{{Skylanders}} Skylanders: Trap Team]]'' takes place in one of these. The player's Skylanders and Glumshanks go to a world where Kaos is a good guy and Eon is a villain named Evilon. Mabu, Flynn, and Persephone are also evil while Trolls are friendly.
310* ''VideoGame/FireEmblemEngage'': This is one of the main ideas behind the "Fell Xenologue" [[DownloadableContent DLC]], as it essentially takes place in one where [[TheBadGuyWins Sombron wins]]. The Four Hounds, who are some of the main game's main villains, are the good guys and have opposite personalities to their mainline counterparts. There's also the royals, who also have opposite personalities to their mainline counterparts, like how [[TheEeyore Alcryst]] is egotistical, or how [[TheAtoner Ivy]] is a corrupt tyrant. It's mentioned that their retainers, who, although long dead at this point, had the opposite personalities as the main counterparts as well. For example, [[BizarreTasteInFood ChloƩ]] is said to have had a PlainPalate, [[AnimalLover Merrin]] is said to have hated animals, [[TeamChef Brunet]] is said to have been a LethalChef, etc. However, [[spoiler:It turns out that the royals are actually [[OurZombiesAreDifferent Corrupted]], so whether or not these are accurate depictions and descriptions of Alternate Elyos' inhabitants while they were still alive is up for debate.]]

312
313[[folder:Webcomics]]
314* In [[http://www.qwantz.com/index.php?comic=35 this strip]] of ''Webcomic/DinosaurComics'', where every comic is the same six images every time, an early story arc involves a mirror universe that is the same six panels... mirrored. Also, every character has goatees.
315* ''Webcomic/IrregularWebcomic'''s "Cliffhangers" theme had [[http://www.irregularwebcomic.net/235.html a visit]] by an alternate Kolonel Haken from a mirror universe where the Nazis were good and Monty was evil. Eventually he was [[http://www.irregularwebcomic.net/comic.php?current=272 killed in single combat]] by the main-universe Haken, so [[{{Pun}} the only dead Nazi was a good Nazi]].
316** Following the history reboot, there have been [[http://www.irregularwebcomic.net/2470.html two]] [[http://www.irregularwebcomic.net/2477.html forays]] to the evil mirror universe. Thus far, the only visible differences are the [[BeardOfEvil beards]], the arrangement of the panels, and Dr Jones Sr.'s dislike of sausages and avoidance of [[http://www.irregularwebcomic.net/2482.html puns.]]
317* ''Webcomic/InWilysDefense'' takes place in a universe where Dr. Wily would like a less exciting lifestyle, Cut Man's the hero, Dr. Light is an egotistical megalomaniac, and X is AxCrazy.
318* [[http://www.shortpacked.com/comic/sharp-cheddar McAwesome]] is apparently a mirror ''shop'' of ''Webcomic/{{Shortpacked}}''
319* ''Webcomic/AgentsOfTheRealm'' has another universe on the other side of the Divide, which has its own set of the Agents and its own five amulets. Judging by LBB, it's more advanced than ours.
320* ''Webcomic/SluggyFreelance'' features an infinity of alternative dimensions. One of them is hinted to be a world of {{evil counterpart}}s, having spawned a malicious version of Kiki, and possibly a selfish jerk version of Torg. (It's not known whether those characters were actually from the same dimension, but they might have been.)
321* ''Webcomic/BobAndGeorge'': In the first AU Bob lands in [[http://www.bobandgeorge.com/archives/010204c an intelligence flipped world.]]
322** While Megaman and Bass swapped intelligence with Protoman (They're geniuses and Protoman's the dumbass), Bob and George swapped temperaments: George became a blind psychopathic murderer, Bob became a flaming homosexual. The regular Bob was...a bit freaked out.
323* The Dimension of Hackneyed Stereotyped Opposites in ''Webcomic/CaseyAndAndy''. Since Casey and Andy are ChaoticNeutral at best, conventional moral flips don't apply to them (instead Andi is a girl who dates God instead of Satan), but Quantum Cop's counterpart is Quantum Crook.
324* ''Webcomic/ElGoonishShive'', obviously. There's the Main Universe's Tedd (the one the story follows), Beta Tedd, Lord Tedd (also known as Alpha Tedd and the evil one pictured in the mirror in the trope image [[note]]the image is not from EGS itself but from a Wotch [[http://archive.is/aNSPx special]][[/note]], the Tedd from Ellen's "Second life" dreams and those are just the canon ones. There's also a paired universe with the main one, which is inhabited by griffons. However, since the two are inextricably connected (described as "two faces of the same coin") one character argues that they shouldn't be considered separate universes.
325* In ''Webcomic/UniversalCompass'' there are 10 Alternate/parallel worlds that each reflect a certain emotion.
326* In ''Webcomic/TheNonAdventuresOfWonderella'', Wonderella and Wonderita end up in one of these...except Wonderella's morality is so fluid in the first place (due mainly to her ItsAllAboutMe mindset) that her mirror counterpart is virtually the same person as her.
327-->[[http://nonadventures.com/2008/03/15/clover-and-over-again/ "The opposite of neutral is still neutral!"]]
328** Later, Wonderita's [[http://nonadventures.com/2013/11/16/lovely-rita-mirror-maid/ mirror counterpart]] arrives in the main universe to try to destroy it. Since Rita is ThePollyanna, mirror!Rita is pure evil. [[spoiler: The Wonderitas end up making out while the Wonderellas watch, drinking beers.]]
329* In ''Webcomic/{{Homestuck}}'', Beforus serves as one for Alternia. At first it appears that the Beforus trolls are the GoodCounterpart to the trolls we know and love, but we soon see that they're easily capable of doing terrible things. The only difference is that they do it with an IDidWhatIHadToDo mentality as opposed to ForTheEvulz.
330* In ''Webcomic/ShatteredGlassPrime'', its Shattered Glass but with elements of WesternAnimation/TransformersPrime. Optimus Prime is a brutal warmonger who seeks to rule Cybertron under his rule and Megatron is a NiceGuy and leader of the Decepticons who seeks to put an end to Prime's reign.
331* Scott from ''Webcomic/BasicInstructions'' briefly visits on in [[http://basicinstructions.net/basic-instructions/2012/2/5/how-to-visit-the-mirror-universe.html this strip.]] There's a very brief HeelRealization moment when it becomes clear that, compared to this universe, his is the "evil" one.
332* Deconstructed in one strip in ''Webcomic/TwoGuysAndGuy'': The mirror universe shown isn't characterised much, but since it's such an accurate mirroring of the other dimension, a mirror-gate leading from one to the other can't be used to travel between them because your counterpart gets in the way.
333* Kickback finds himself in one in ''Webcomic/{{Insecticomics}}''. Except that the Insecticons aren't really evil so much as they're irresponsible and fun-loving. The mirror universe Insecticons are accountants. And Lazerbeak is a male ninja instead of a female [[PiratesVersusNinjas pirate]]. Who won't let Kickback wear a dress because he's not a girl.
334* Universe 13 Kakarot in ''Webcomic/DragonBallMultiverse''. At some point in his universe, [[Franchise/DragonBall Goku]] regained his destructive instincts, wiped out humanity, and proceeded to GoMadFromTheIsolation. The end result is [[NightmareFuel terrifying]].

337[[folder:Web Originals]]
338* In the ''Roleplay/LeagueOfIntergalacticCosmicChampions'', the LICC Universe is mirrored by the KILL universe.
339* ''WebOriginal/ProtectorsOfThePlotContinuum'' has a Mirror Universe that is an obvious Shout Out to Star Trek, including Beards of Evil.
340* The RPG Net message boards once [[http://forum.rpg.net/showthread.php?t=413172 featured]] a wonderful idea for a ''Literature/{{Discworld}}'' mirror universe. The Disc is torn by war between the scarily charismatic Last King, ruler of Ankh-Morpork and the Plains, and the all-powerful Crone, who controls the Ramtops. Between them are the Crone's former apprentice Magrat, Havelock the assassin, and Samuel King-killer. And their leader, the last survivor of the Silver Horde, Rincewind Spellholder.
341** Later additions included the Wizard-Killer, a bestial creature that haunts the library of the abandoned UU; Susan the Vain, who plays both sides, seeking to replace her grandfather as Champion of the Auditors; the History Monks, who presumably have decided this is all ''meant'' to happen for reasons of their own; the Chalkland Hag, who seeks to challenge the Crone and has turned a society of harmless brownies into an unstoppable army; Lady Sybil, who breeds war-dragons for the Last King and seduces others to her own ends; and Reginald Shoe, who has fled Ankh and turned Pseudopolis into an undead police state. Amongst others.
342* ''Website/GaiaOnline'' recently featured a literal Mirror Universe in the form of the Dark Reflection random item generator. [[UnluckyEverydude Unlucky Everygirl]] Kanoko get sucked into a bizzaro Gaia, and Gaians have to venture through the mirror to rescue her. Bizzaro Gaia features strange versions of the most famous Gaian [=NPCs=]. Some of these are fairly basic changes. (Agatha and Rina swapping ages, Moria and Sasha swapping clothing styles, Ian and Rufus swapping species), while others are a bit more bizarre. (Scheming con man Nicolae is now a priest, Liam has become a woman, his yaoi-bait roommate Gino has become his ''boyfriend'', and Edmund has become a huge nerd.). Various inversions of items are present as well. (Gaia-Tan has become Gaia-Sama, Grunny has become Prunny, etc...)
343* ''WebVideo/TheAllenAndCraigShow'', in [[https://www.youtube.com/watch?v=4uxiF5NO1j8 Episode 12]], features two gangsta counterparts to Allen and Craig that share many similar characteristics but have a more "urban" edge.
344* [[Blog/ThingsMrWelchIsNoLongerAllowedToDoInAnRPG Mr Welch]] parodied the concept with a superhero player character that was, as usual, rejected by his gamemaster.
345-->325. Even if he was a paragon of humanity in his alternate dimension, Good Hitler is not an appropriate superhero concept.
346* In ''Podcast/WelcomeToNightVale'', [[spoiler:Desert Bluffs]] is implied to be a Mirror Universe. A sandstorm rolls into Night Vale, bringing with it doubles of all the citizens, who fight each other to the death. It opens a portal in Cecil's radio booth, transporting him away to places unknown, and depositing another man in his place. In the episode's POVSequel, we find out where Cecil went, and learn that Night Vale isn't actually all that bad, [[EvilIsVisceral by]] [[MeatMoss comparison]].
347* ''WebVideo/AtopTheFourthWall'' has Iron Liz get transported to one in the ''Star Trek #2 (Gold Key)'' review. There exists an EvilTwin of Linkara (complete with a mustache and beard) who thinks ''ComicBook/AllStarBatmanAndRobinTheBoyWonder'' is genius and that Rob Liefeld's artwork is "beautiful." His version of the opening also suggests he finds ''ComicBook/TomStrong'', ''ComicBook/{{Watchmen}}'', ''ComicBook/BoosterGold'', and ''ComicBook/{{Starman}}'' to be terrible books. Dr. Insano is far more sane and heroic, declaring himself the champion of science. Pollo is essentially the same, just in the [[Series/MysteryScienceTheater3000 Tom Servo]] body. Same with Mirror Liz, whose only major difference is that she loves the 4th edition of Dungeons and Dragons (which is how the main universe versions of Pollo and Linkara knew something was wrong.) [[spoiler: More disturbingly, the Mirror version of Margaret, the girl whose soul was sacrificed by a cult to create the magic gun, wasn't forced into it against her will. She was a willing volunteer.]]
348** Other characters, recurring and otherwise, are also from mirror universes: Iron Liz's evil counterpart Judas Liz; Mechakara, who is actually an evil Pollo wearing the skin of his universe's Linkara; and Dr. Linksano, who is apparently Linkara, but not really, and might be Insano's brother, or a version of him from another universe, or... it's complicated.
349* ''Podcast/{{Hello From the Magic Tavern}}'' has a mirror universe where our heroes are evil and act on behalf of the Dark Lord. Evil Arnie has a goatee and is always trying to tell his companions about (Evil) Earth, much to their annoyance.
350* ''WebAnimation/{{Dreamscape}}'': Melinda, Ethan, and Betty are from one of these, among others.
351* Cooking Youtuber [[https://www.youtube.com/user/aragusea Adam Ragusea]] occasionally calls on this trope almost by name when he mentions the mirror world featuring Adam with a goatee. This world is brought up whenever Adam points out that the way a food is traditionally made is just that, an arbitrary way of making it that crystalized as ''the'' way of making it and that it isn't always the best way to make a given dish at home, which is highlighted by having the method he proposes be the default of this world and Mirror Adam covering our traditional method on ''his'' show. Mirror Adam usually says something like "It doesn't have that ''[abitrary feature]'' tradition really demands," or "It's an okay substitute," and always ends his stint on the show with "Long live The Empire."

354[[folder:Western Animation]]
355* One episode of ''WesternAnimation/Rugrats1991'' has Chuckie and Tommy thinking that they landed in "Mirror Land" when they flipped over a mirror. Thanks to a series of [[ContrivedCoincidence contrived coincidences]], HilarityEnsues.
356* ''WesternAnimation/SouthPark'' parodied the ''Star Trek'' episode with their own Mirror Universe, from which visited an alternate Cartman. Exactly like the alternate Spock in "Mirror, Mirror", the alternate Cartman was bearded -- but being the moral opposite of the "real" Cartman, he was of course kind, soft-spoken, polite, and gentle. Hilariously, the show depicted the twins on screen at the same time with a [[StylisticSuck deliberately obvious]] SplitScreen effect. Later on, we see that Kenny is rich, Stan and Kyle are Cartman-level [[{{Jerkass}} Jerkasses]], and [[Music/IsaacHayes Chef]] is a skinny white insurance salesman.
357* ''WesternAnimation/DarkwingDuck'' has the Negaverse[[note]] [[Manga/SailorMoon Not that one]] [[/note]] from which [[MultipleChoicePast one version of]] Darkwing Duck's EvilTwin Negaduck originates, where he evidently rules with an iron fist. Nega-Honker has the (regular) Tank's personality and morality while Nega-Tank has Honker's, the rest of the Nega-Muddlefoots and Nega-Launchpad are thuggish psychotic killers, and the Negaverse versions of the other four members of Negaduck's "Fearsome Five" are known as the "Friendly Four" until Darkwing Duck retrains them. Interestingly, despite being Negaduck's ward, Nega-Gosalyn has the same general morality as her prime universe counterpart (much like bearded Spock), but a reversed personality: whereas regular Gosalyn is a rough-and-tumble sports-loving TomBoy and BrattyHalfPint, Nega-Gosalyn is a sweet and obedient well-behaved [[PinkMeansFeminine pink-dress-wearing]] young lady.
358* There's a mirror universe in ''[[WesternAnimation/CaptainNTheGameMaster CaptainN]],'' accessed by going through an actual mirror. Oddly it's not just characters' alignments that are inverted. For example, one lady is shown "doing laundry" by covering her clean clothes with dirt.
359* In ''WesternAnimation/BatmanTheBraveAndTheBold'', Batman travels to one of these when the Red Hood, [[spoiler:an alternate version of the Joker]], needs his assistance. He seems to enjoy repeatedly punching out the alternate version of Green Arrow a little too much...
360** There's an EvilCounterpart to the WesternAnimation/JusticeLeague called the Injustice Syndicate, which has evil counterparts of Batman (Owlman), ComicBook/BlueBeetle (Scarlet Scarab), ComicBook/GreenArrow (Blue Bowman), and ComicBook/RedTornado (Silver Cyclone) among others.
361* The ''WesternAnimation/SWATKats'' episode "The Dark Side of the SWAT Kats" featured the titular team being warped to a dimension where their equivalents are evil (as is that of their ally, Deputy Mayor Callie Briggs). The universe wasn't entirely swapped, however - some major characters retained their 'correct' moral alignments. (There were other more subtle changes as well, such as the Enforcers using fixed-wing aircraft rather than helicopters.)
362* ''WesternAnimation/MegasXLR'' has [[BadFuture a version of this]] in its two-part "Rear View, Mirror Mirror" storyline. In this timeline, main character Coop abandoned the titular Megas shortly after defeating the series' BigBad - losing his mind as boredom and battlelust sank in, culminating in the conquest of earth and several solar systems. Coop seems more offended at his alternate self being athletic and muscular (as opposed to...large) rather than evil, though.
363* ''The World's Greatest WesternAnimation/{{Superfriends}}'' had such an episode, "Universe of Evil". Each of the Superfriends received an EvilMakeover (Aquaman with an eyepatch! Robin with a [[GoodHairEvilHair pencil mustache!]] Wonder Woman letting herself go!) [[http://superfriends.wikia.com/wiki/Super_Enemies See them here.]]
364* ''WesternAnimation/BuzzLightyearOfStarCommand'' had as a minor villain the [[SarcasmMode imaginatively dubbed]] and yes, goateed, Evil Buzz Lightyear who came from a parallel universe that he had conquered. He's ''exactly'' as evil as Buzz is good. There are parallel versions of the other main characters, except none of them are evil, just jaded from being under Evil Buzz's thumb. Oh, and the inverted counterpart for Emperor Zurg? He works at a local diner.
365* ''WesternAnimation/CodenameKidsNextDoor'' had one in which even the acronyms were reversed - the counterparts to the Delightful Children From Down The Lane were the Little Traitorous Dudes From Children's Defence, who opposed the iron grip of the Destructively Nefarious Kids, who were led by Numbuh -4, who had attained a goatee to make himself look even eviller. Fortunately, since the regular Numbuh 4 is brave to the point of recklessness and a strong physical fighter, Numbuh -4 was a coward and weakling. Also, Numbuh -86 was a sweet girly girl.
366** Other differences include a dumb and weak-willed Numbuh -1, Numbuh -2 was also dumb but good at making jokes, Numbuh -3 is a bitch, and Numbuh -5 is a {{geek}}. Strangely, the LTDFCD still talk in unison like their main counterparts, though in [[SurferDude surfie accents]] and they still work for "Daddy", who, unlike Father, is an extreme worrywart who cares a lot for his kids.
367* ''WesternAnimation/GIJoeARealAmericanHero'''s two-part episode "Worlds Without End" had several of the Joes traveling to a CrapsackWorld that bordered on this; while most of the alternate versions of G.I. Joe and Cobra were still morally similar to their counterparts in the regular universe, Cobra's having conquered the world made it the legitimate government of that world and G.I. Joe an enemy of the state. Also, in a bit of a twist, [[spoiler: the alternate Baronness was [[DatingCatwoman romantically involved]] with Steeler's counterpart before he was killed in action, and this was one of the stronger influences which persuaded Steeler to stay with her in her world at the end when most of his teammates returned to their own world. (A couple of the others also stayed with him to help revive G.I. Joe's resistance movement in that world.)]]
368* ''WesternAnimation/TheRealGhostbusters'' episode ''Flip Side'' had Egon, Ray, and Peter end up in a flip dimension where ghosts are the natural populace and are menaced by humans. While there, they encounter ghostly versions of themselves called the Peoplebusters.
369* ''WesternAnimation/HeyArnold'' had an episode where Arnold goes into the country to visit his weird cousin Arnie. All of the people he meets are counterparts of his friends, but they all appear in pairs, with each one displaying the attributes of the other's counterpart: Harold and Rhonda appear as Harry and Rhoda, with Harry being slim and fashion-conscious and Rhoda being a fat slob. Stinky and Phoebe are seen as Stumpy and Fifi, with Stumpy being intelligent and Fifi being simple-minded and Gerald and Sid appear as Gerard and Kid, with Gerard being the whiny one and Kid being cool. In the end, [[spoiler: it turns out that it was AllJustADream.]]
370* ''WesternAnimation/SonicUnderground'' had the hedgehogs enter one where they were the tyrants and Robotnik was a Freedom Fighter. It ended with them [[HeelFaceTurn redeeming]] their evil counterparts. Strangely, there was no mirror version of Queen Aleena.
371* ''WesternAnimation/Ben10Omniverse'': Ben 23 has a take on it, where the Ben there is a {{Jerkass}} who believes that all aliens (except his transformations) are evil. His RoguesGallery includes a Tetrax with a diamond BeardOfEvil. In the end, it turns out the BigBad was really Azmuth, trying to get back the Omnitrix from Ben (who he, with good reason, believed was abusing it), and Ben himself wasn't evil, just misguided. Since Tetrax was a good guy as well, the only real alliance difference was Seven-Seven (who worked for Azmuth and thus was also good).
372** There's also Mad Ben (a ''Film/MadMax'' parody), Bad Ben (a PaletteSwap with black hair), Benzarro (from a ZombieApocalypse universe), Nega Ben (Ben as a {{goth}}), and No-Watch Ben ([[BadassNormal self-explanatory]]). All but the last were evil.
373* ''WesternAnimation/SpaceStars'' had an episode with an alternate universe where ''WesternAnimation/SpaceGhost'''s counterpart was Space Spectre, a ruthless SpacePirate.
374* The ''WesternAnimation/DangerMouse'' (2014) episode "Sinister Mouse'', DM meets his counterpart from a mirror universe called the Twistiverse, who is a master criminal in a red bodysuit. He is opposed by Danger Toad (Twistiverse Baron Greenback) and secretly works for [[spoiler: the evil genius Baron Penfold]]. Later episodes feature Twistiverse versions of other characters; "Twisted Sister" features a version of Professor Squawkencluck who is not only evil but, when Squawkie accidentally turns herself into a little girl, has turned herself into an old woman.
375* ''WesternAnimation/{{Rupert}}'' featured a rather literal example of this trope in "Rupert in Mirrorland", where Rupert Bear's friend the Professor uses an invention of his to reveal that inside all the mirrors was a world where everyone's reflections are sentient beings. The Professor's reflection is shown to be evil, but it's only because of a side effect of the Professor's experiment and the reflections of everyone else are as nice as their Nutwood counterparts.
376* ''WesternAnimation/{{Kaeloo}}'':
377** The show had an episode where the main four get teleported to an alternate universe where Kaeloo is usually a huge monster and transforms into a cute little girl when angry, Stumpy is a genius, and Quack Quack and Mr. Cat have each other's personalities and traits. [[spoiler: The episode turns out to be [[AllJustADream a dream]] [[{{Cloudcuckoolander}} Stumpy]] had, the events of which he is narrating to Kaeloo.]]
378** Another episode had them go to a universe where they study academic subjects all day instead of playing games and hanging out, the normally fun-loving, friendly, hyperactive Kaeloo is a SternTeacher, Stumpy, who is usually stupid, is smart, and Mr. Cat, one of the smartest in the cast, is a moron [[ExtremeOmnivore who eats books.]]
379* [[DiscussedTrope Discussed]] and [[SubvertedTrope subverted]] in the ''WesternAnimation/{{Futurama}}'' episode "The Farnsworth Parabox" when the main cast meet the versions of themselves from an alternate universe, and the doubles pair off to keep an eye on each other since [[WrongGenreSavvy each side is convinced]] that the other represents the "evil" universe (according to Alternate Farnsworth, "when you create a parallel universe it's almost always populated by [[EvilTwin evil twins]].") In fact, personalitywise the alternate cast are indistinguishable from the cast as we know them, the key difference being a handful of relatively mundane changes in circumstance caused by [[HeadsOrTails coin flips having the opposite outcome]].
380-->'''Alternate Bender:''' Oh, this is awful. [[TokenEvilTeammate Somewhere there's a more evil Bender than me]]. [[CardCarryingVillain I DO MY BEST, DAMMIT!]]
381-->'''Alternate Farnsworth:''' Leela. The ''good'' Leela. I want you to snoop around the other universe and find out how evil they are. ''(handing Alternate Leela a ray gun)'' Here.
382-->'''Leela:''' I tell you they're not evil! ...But don't be confused! They ''are'' jerks.
383* An episode of ''WesternAnimation/PeterPanAndThePirates'' has Peter going into the CenterOfTheEarth were everything is inverted and they have all copies of themselves; the Lost Boys are slaves, Hook is a pharaoh-like figure assisted by Egyptian-looking versions of the Pirates, and so on.
384* ''WesternAnimation/{{The Adventures of Rocky and Bullwinkle}}'', in the serial ''Amazamoose and Squirrel Wonder'' (2019), required Moose and Squirrel to venture into Opposite World, where Boris and Natasha were heroes fighting against the sinister schemes of Evil Rocky and Evil Bullwinkle.
385* ''WesternAnimation/OhNoItsAnAlienInvasion'': In one episode, Louis is sent to an alternate dimension where S.W.E.E.T. are evil (they stole the Brainlings' technology and used it to abduct all the world's adults), and the Brainings are good (they're hiding in Swell-Mart and are fighting back against S.W.E.E.T. to restore order to the world).
386* ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' had an episode where Jimmy's evil clone uses a modified duplication device to make an evil copy of the entire earth except for Jimmy so that he will have an entire world where everyone is as evil as he is. Jimmy has to travel to the evil earth and reverse the duplication process because the duplicator also has the side effect of causing the original to fade away.
387* ''WesternAnimation/SupermanTheAnimatedSeries'' did this in "Brave New Metropolis"; Lois finds herself in a Metropolis ruled by Lex Luthor, with Superman as his superpowered enforcer, having gone KnightTemplar after [[spoiler:failing to save his dimension's Lois from a car bomb]].
388* ''WesternAnimation/TheSmurfs2021'': In "The Pluffs", Brainy and Smurfblossom find themselves in a parallel universe where the Smurfs (or rather, the titular Pluffs) are [[AlwaysChaoticEvil gray, mean, and have nothing better to do than bully each other]] or kindly folk like Bigheart (Bigmouth), or the kindly wizard Caramel (Gargamel). Even the wildlife are reversed, as the butterflies bite people and [[JustTheIntroductionToTheOpposites vicious rabbits chase cats up trees.]]
389* An episode of ''WesternAnimation/AtomicPuppet'' saw Joey and AP fight evil versions of themselves from one such universe. The mirror Atomic Puppet also switches roles, with Joey as the puppet and AP as the wielder. Later, they meet the mirror version of [[BigBadWannabe Mookie]], who is the greatest superhero in his world and has a mustache for some reason.
390* An episode of ''WesternAnimation/TheSecretSaturdays'' has a magic mirror bring The Mondays, their [[EvilCounterpart evil counterparts]] from a MirrorUniverse, into their world. Each of them has their personalities reversed ''and'' some physical differences to tell them apart. In addition, they are supposed to be made of Anti-Matter, which causes reality to go crazy every time one of the characters approached his or her counterpart ([[ArtisticLicensePhysics Actually, if they were made of antimatter they would have exploded like nuclear bombs the moment they entered the positive universe]]... which is [[spoiler: exactly what happens when Argost tries to absorb both Zak Saturday and Zak Monday's powers in the series finale]]).
391* The ''WesternAnimation/MiraculousLadybug'' special "Miraculous World: Paris - Tales of Shadybug and Claw Noir" centers around Ladybug and Cat Noir meeting a benign version of [[BigBad Hawk Moth/Monarch]] from a world where their counterparts are villanous enforcers of that world's resident Big Bad. Outside those three, the mirror universe aspects are downplayed; it's shown that the alternate versions of Alya, Nino, and (according to a throwaway line) ChloƩ are all on the same moral wavelengths as their main universe counterparts.
392* ''WesternAnimation/AdventureTimeFionnaAndCake'': In "The Winter King", the gang ends up in an alternate universe where their version of the Ice King managed to overcome the Crown's curse and is a benevolent and beloved ruler. He is also frequently kidnapped by the psychotic Candy Queen, the evil version of Princess Bubblegum, who comes from a corrupt version of the Candy Kingdom. [[spoiler:However, this is {{subverted|Trope}} at the end of the episode, where it turns out that this universe was once very similar to the original Ooo, except the Winter King was a sociopath who figured out how to transfer the Crown's curse on to Bubblegum so he could enjoy the power and immortality without the insanity. Fionna accidentally saps the magic out of the crown, killing the Winter King and freeing Bubblegum.]]
