Leela: (Facing her alternate universe counterpart) We're exactly the same, I know all her moves. Therefore, I have the upper hand. Hiiyyyya-ow!
"Nice to meet you, another myself."
A term that originates from Fighting Games. A Mirror Match is when one character fights the same character. The match is like looking into a mirror. This can be a rather tricky experience, as the two characters are, by definition, evenly matched; it comes down to which player knows the character better. If these occur in the game's story mode, it's usually Handwaved as a mysterious impostor and tends to have no impact on the story despite the interesting possibilities it presents.
Collectible Card Games use the term as well, but with a different meaning - in a CCG, a "mirror match" is when two players with the same deck theme play against each other. While the decks likely differ in spots, the central strategy is the same.
The Trope Namer is the first Mortal Kombat; the last enemy you fought before the Endurance matches was yourself. Most characters fighting their mirror selves never seem to notice, nor is it explained how such a thing is possible, though it may be lampshaded if the game features pre- or post-match banter.
Character Tiers can force almost every single match to be a Mirror Match because everyone spams the top tier character(s). This trope is not limited to fighting games, though if it appears in other genres or other media, it is more likely to have an explanation.
Anime & Manga
- In the Yes! Pretty Cure 5 movie, the Precures go into a mirror world and fight evil Cures. The Fan Nickname-happy fandom had a field day with Cure Nightmare, Cure Deadly Nightshade, Cure Bridget...
- In Naruto Shippuuden, a mirror match occurs simultaneously with four ninjas, each having a copy of themselves. They eventually beat their copies by realizing that they can become better than their copies, because the copies don't improve but they do, because they've sworn to improve every day. (Huh?)
- A one-shot character in Hikaru no Go attempts to stalemate Akira Toya by mimicking every move Akira makes, starting by taking away the spot in the center board. Akira wins anyway by tricking him into a position where he manages to capture, breaking the guy's strategy. (Which is later revealed to be low-grade and easily countered.)
- Magical Girl Lyrical Nanoha has Subaru and the Numbers Cyborg Nove, with the latter's appearance, equipments, and abilities all being similar to the former and her sister since she was created by cloning their mother, Quint. Unfortunately for Nove, Subaru revealed during her Unstoppable Rage that she has the ability to kill cyborgs like her in one hit, so it didn't turn out to be the even match she had hoped.
- Played straighter with Subaru and her sister Ginga, since Subaru had to restrain that ability of hers for obvious reasons. Not to mention the fact that they're both clones of their mother Quint.
- Those Who Hunt Elves has this near the end, with all the protagonists having to fight clones of themselves. Rather disappointingly enough, they were unable to find any way to defeat them.
- Magic Knight Rayearth had this as a Secret Test of Character for Fuu.
- Fushigi Yuugi has Miaka having to face an evil clone of herself, which turned out to be a Secret Test of Character.
- Subverted in Bleach. Ichigo's inner Hollow looks like a photo-negative version of Ichigo, and wields the same weapon, yet he uses moves Ichigo never even thought of, such as spinning Zangetsu by its wrapping/chain.
- The villain in Saitama Chainsaw Shoujo shows some doppelganger abilities when she takes the physical shape of protagonist Fumio, complete with clothing, equipment, and muscle-memory of her fighting style.
- The whole plot of Pokémon the First Movie revolved around Mewtwo luring trainers to his island and making clones of their Pokémon, leading to a climax which sees each Pokémon fighting its clone.
- One chapter of Magic Kaito had Kaito Kid facing an android double that could replicate his every move. Kid defeated the double by shooting himself in the head. Kid's gun was a toy that fired playing cards, resulting in a sore ear. The robot's gun was a weapon that fired bullets, resulting in a trashed robot.
- Subverted in Oto x Maho, where Kanata faces off with an evil duplicate. Kanata prefers physical attacks, while the Evil Twin can only use magical attacks.
- In the Sonic the Hedgehog anime, Metal Sonic is programmed to be an exact copy on regular Sonic, and it is even implied that they share a mental link (see the part when Sara is kicking Metal Sonic in the head, and regular Sonic is writhing in pain). The two are constantly seen running into each other, until finally, Sonic says this quote:
Sonic:You might know everything I'm going to do but that's not going to help you since I know everything you're going to do! Strange, isn't it!?
- Erza vs Edolas Erza in Fairy Tail. Natsu was freaked out the moment he saw those two fighting.
- In Digimon Adventure, Etemon trapped the Chosen in an arena and set a captured Greymon on them; he also arranged a trap so as to trap all of the Chosen's partner Digimon except Taichi's Agumon, whose evolved form is Greymon. Needless to say, the two fight.
- Played with in the Slayers OAVs: The
heroesprotagonists end up looking into a mirror that produces duplicates of them with radically opposed personalities. However, the protagonists are naturally egotistical and prone to violence, which leaves their mirrors as demure pacifists - terrifying the protagonists. One could say the mirror-duplicates win a psychological battle rather than a physical one.
- In Captain Atom #56 and #57, Cap fights a battle with his own dark side, what he calls "the chaos I have inherited."
- In the 50's & 60's, Wonder Woman ended up with an improbably large number of storylines that involved her fighting doppelgangers of one sort or another.
- Besides his countless fights with Bizarro over the years, Superman has also gotten into fights with his robot doubles when they've gone rogue, a successful non-Bizarro clone made by Luthor, a Split At Birth Evil Twin called Supermenace, and even his time-displaced younger self who was possessed by an enraged Pete Ross at the time.
- The original, very brief appearance of Spider-Man's clone was basically a one-issue, pretty cool Mirror Match fight that ended with the clone killed in an explosion. Twenty years later, the clone got brought back for a convoluted storyline that dominated the title for a couple of years.
- One of the earliest Stan Lee-scripted stories featuring The Mighty Thor pitted our hero against an exact duplicate created by a Mad Scientist. Cut Lex Luthor a Check much?
- Captain America #350. Steve Rogers (as the Captain) vs. John Walker (as Captain America) at the behest of the Red Skull (who was Back from the Dead in a cloned body of Rogers). The Skull even took on the winner - Rogers - thus providing a truer Mirror Match (since Walker was actually taller, stronger, and more prone to rage than Rogers)... except that the Skull-Rogers "fight" was really an excuse for the Skull to use his Dust of Death on Rogers. Walker intervened, however, and the Skull got a taste of his own bad medicine.
Films -- Live Action
- The "evil robot usses" from Bill and Ted's Bogus Journey.
- In Superman III, Superman is exposed to some flawed synthetic kryptonite and turns "evil" (read: superpowered Jerkass). His inner conflict is played out onscreen when Clark Kent manifests in front of him and they fight until Clark wins, then tears open his shirt revealing the untarnished S-shield and flying off to undo the damage he did when he was "evil", ending the only enjoyable scene in an almost universally reviled movie.
- Subverted in Scott Pilgrim vs. the World, when Scott meets Nega-Scott. There was only the vaguest of foreshadowing and no real explanation, although several interpretations are possible. It looks like they're going to fight...but then they get to talking, and it turns out they have a lot in common. They decide to meet for brunch the next week.
- It plays out much differently in the comics, as we learn that Nega-Scott has a much larger purpose. He's a manifestation of Scott's screw-ups when it comes to relationships and himself in general. Instead of defeating Nega-Scott, our hero has to come to terms with his dickery and has to merge with Nega-Scott in order to become a better person.
- In The Empire Strikes Back, Luke Skywalker has to go into a cave as part of his Training from Hell and faces off with a vision of Darth Vader. He beheads the apparition, only to discover it has the same face as him under its mask.
- Appears to be in play in Insurgent (the sequel to the film version of Divergent), if the trailer released in late 2014 is to be believed.
- In Book 19 of Lone Wolf, the main antagonist is an Evil Knockoff called Wolf's Bane. The main plot involves Lone Wolf chasing his evil impostor to try to bring him to justice. When you finally face him in combat, he has the same stats and abilities as you, the only difference being your respective Hit Points if he was wounded earlier.
- A few of the Fighting Fantasy gamebooks that allow the player to use magic typically include a "Creature Copy" spell that is Exactly What It Says on the Tin. When cast, the spell creates a magical duplicate of whatever monster you're fighting to fight
- In the third volume of Grail Quest Solo Fantasy, one of the enemies is an evil version of yourself created by looking in a magic mirror (the only difference is that it has only half your current LIFE POINTS).
- Rand from The Wheel of Time series fights a more or less literal Mirror Match when a "bubble of evil" spontaneously causes his reflections to jump out of mirrors and fight him to the death. Eventually he starts wising up to the situation and extinguishes his Flaming Sword, causing his reflections to do the same (to their confusion) and making the fight slightly easier.
- An example from the Star Wars Expanded Universe; during the Force Heretic novels, Jedi Tahiri Veila has a series of nightmares/hallucinations/Force-trance-somethings which pit her again various aspects of herself, including her Vuuzhan Vong implanted personality (looong story), which takes the form of - you guessed it - a mirror image of herself. Interestingly, they're actually mirror images: Tahiri is left-handed and Riina right-handed, and that's the only way to distinguish between them.
- Hell, even Luke Skywalker has to deal with an evil clone of himself in one novel; the clone was imaginatively named "Luuke" Skywalker. In defense (as someone elsewhere noted), it was named by a Cloudcuckoolander villain...
- Both of the clone characters in that trilogy have a doubled "u" in their name. There's a reason for this...
- Hell, even Luke Skywalker has to deal with an evil clone of himself in one novel; the clone was imaginatively named "Luuke" Skywalker. In defense (as someone elsewhere noted), it was named by a Cloudcuckoolander villain...
- In Hard Magic, Sullivan twice has to go up against his brother, both of whom have Gravity Master powers.
- A few of the Jason X novels had Jason battle clones of himself.
Live Action TV
- This is used quite a lot in Power Rangers, being a nearly once-seasonally tradition. Often they were led by a Monster of the Week. Zeo and RPM (so far) are pretty much the only seasons who haven't had it in some form - if not identical copies, then an Evil Counterpart team will be featured, like Space's Psycho Rangers, the Spirit Rangers and Five Fingers of Poison in Jungle Fury. Oddly, only once (the very first use of the gimmick waaay back in the original series) were they used to ruin the Rangers' good name, and never have they been used to pose as a friend and backstab a good Ranger.
- Oddly, the Sixth Ranger seldom gets a copy. But sometimes Tommy's subverted it, facing his past selves.
- On the Darker and Edgier side of the Toku coin, Kamen Rider tends to have the main rider fight against an evil (and usually dark colored) counterpart, for example: Ryuki vs. Ryuga, Kabuto vs. Dark Kabuto, Kiva vs. Dark Kiva.
- Dragon Knight inverts this by having the first example flip sides. Ryuga is a good guy, and Ryuki is the bad guy.
- Angel vs Angelus. 'Nuff said.
- Arnold Rimmer from Red Dwarf encounters this in Mass Effect 2, Lister encounters it in Psirens, Kryten encounters it in Legion and Cat encounters it in Camille
- Olivia of Fringe fights her Alternate Universe counterpart in the season 2 finale, Over There, Part 2.
- Disappointingly averted in The Secret World of Alex Mack. Alex gets an evil duplicate, but despite both of them having Telekinesis and electric powers, they never actually try to fight—Alex winds up just chasing her evil twin around until they recombine.
- Played straight in Charmed when Paige and Phoebe and their evil Mirror Universe counterparts fight. Leo comments that they are too equally matched and neither side could win, so the fight went on and on until they realized this, called a truce, and formed an alliance instead.
- Subverted in one episode of Star Trek: Voyager:
Tuvok Impostor: Logic states that we are evenly matched.
- Lord John Roxton gets an Evil Twin in one episode of Sir Arthur Conan Doyle's The Lost World after he is cursed for disturbing a graveyard's peace. The protector takes the ruthless and violent part - basically the hunter part - out of him andd gives him a life of his own. Evil!Roxton tries to kill the good one, using Marguerite as bait. It ends in a Mirror Match.
- Knight Rider: KITT facing off against his Evil Twin prototype KARR.
- Mariah Carey's video "Heartbreaker" shows Mariah getting in a Cat Fight with her Evil Twin in a ladies' room.
- Madonna's "Die Another Day" shows two Madonnas swordfighting.
- Britney Spears fights herself in "Hold It Against Me".
- Lights exchanges energy bursts, broken property, and a few punches and kicks with her Evil Twin in "Ice."
- Kelly Clarkson races against herself in "Go".
- P!nk does some er...interesting things with hers in "Sober".
- Kelly Rowland faces off against herself in "Commander".
- The WWF tried to pull off a Mirror Match in live action at Summerslam 1994, with a match pitting The Undertaker against...The Undertaker. Unfortunately, this proved impossible to pull off with any degree of realism, as the false Undertaker they got was quite a bit shorter and slimmer than the actual Undertaker. However, this didn't stop Vince McMahon from proclaiming, "It's like looking into a mirror!"
- WWE have tried it once again. This time, it's Sin Cara vs. Sin Cara, and surprisingly, it doesn't suck.
- Chess and Draughts/Checkers are obviously Mirror Matches, although it could be claimed that the fixed move order makes White and Black rather different prospects to play despite being otherwise identical.
- A major part of the Metagame in Magic the Gathering is being ready for the Mirror Match.
- Dungeons & Dragons has a magic item called the Mirror of Opposition, which creates a clone of anyone looking into it with all the character's items and abilities, but the exact opposite alignment (Lawful Good produces a Chaotic Evil clone, Chaotic Good produces a Lawful Evil clone, while True Neutral produces a clone of random allignment, and so on), resulting in a big fight after which the clone and its items vanish. (The below-mentioned Neverwinter Nights example "uses" this item.)
- It's also used in the Tales of the Sword Coast expansion of Baldur's Gate. In the sequel, Big Bad Jon Irenicus pulls a similar trick during the battle in Spellhold. On a similar note, high-level mages can use the Simulacrum spell to summon a (weaker) copy of themselves.
- The Dungeons & Dragons module Quest for the Heartstone has the climactic battle a one on one fight between each Player Character and a duplicate created by the Heartstone. Victory meant you stay yourself, defeat meant you change to the opposite alignment. The Players have a slight advantage over their duplicate in that the duplicate had 10 hit points less than them.
- In Changeling: The Lost, one of the central conflicts for changelings is how they deal with their fetch, the magical imposter that was left behind when they were abducted. Responses to coming back after the horrific ordeal that is service to the True Fey is hard enough without having to deal with something that wears your face and has been living (or ruining) your life while you were away. Depending on how the Storyteller wants to play things, the fetch could be a malicious sociopath out to ruin the changeling's good name, a dark reflection of the changeling (or even a light reflection—nothing stops the fetch from being a better person than the changeling it replaced), or an innocent bystander with no clue why this horrible creature it dreams about wants to kill it and take over it's life.
- Shinobi for the PS2 has Moritsune.
- In Castlevania Judgment, both the combatants have special comments and a (shared) unique win quote for a mirror match.
- Darksiders does this when you get to Eden, where you're forced to fight a particularly bastard version of your self that can use some of your limited use moves as many times as he cares.
- One of the recurring bosses in Castlevania is the Doppelganger, which imitates the player's appearance, moves, and (sometimes) stats.
- Some levels of Blaster Master have mooks that look like gray versions of the player character.
- As a trial to become a Paladin, Cecil in Final Fantasy IV has to face a doppelganger of himself as a Dark Knight. In the Bonus Dungeon, Kain has to face a dark form of himself before it transforms into Lunar Bahamut. Revisited in Final Fantasy IV: The After Years when Kain's repressed dark urges manifest as an Enemy Without and they duel for dominance.
- Crisis Core features digital recreations of Zack as opponents in a handful of missions.
- In Kingdom Hearts: Birth By Sleep, Master Xehanort possesses Terra's body to create the young Xehanort, but Terra's hatred reforms his armor as the Lingering Sentiment to continue fighting. All of Xehanort's attacks are attacks usable by Terra, and they even share the same battle stance.
- Thematically done with Sora vs Roxas and Ven vs Vanitas, Roxas being Sora's Nobody and Vanitas being the dark half of Ven's split heart. Done more traditionally with the minibosses Anti-Sora and Shadow Roxas.
- God Hand provides two examples: The first is Azel, the owner of the other God Hand who prefers to call himself Devil Hand as a contrast to the player character, Gene. Both characters use essentially the same moves on one another, and can even engage in Fist of the North Star-esque pummel duels. The second example is the final arena match, where Gene faces a carbon copy of himself (actually a reskin of Azel) for 99,999 gold.
- The original Devil May Cry uses this trope quite literally when Nelo Angelo aka Vergil emerges from a mirror to battle you. Both brothers have similar abilities (swords and projectiles).
- The third one featured a Doppelganger boss. Defeating it would earn you the Doppelganger style, where you create a shadow of yourself that copies all of your moves.
- Averted in Ninja Gaiden III for the NES. The fifth boss is Ryu's doppelganger, but he has his own sprite (which is twice the size of the player's) and attack patterns. The doppelganger is revived as the boss of the next stage, who has a completely different form.
- Bayonetta uses this trope quite literally as well. And how? She fights herself at the end the "Angel Slayer" bonus Chapter.
- In Quest for Glory: Wages of War, the party the Hero has assembled fight mirror duplicates of themselves (created by magic mirrors, of course). The evil duplicates blatantly cheat by being significantly more powerful than the originals. The Hero's own fight is unwinnable without assistance.
- In Star Trek: 25th Anniversary (video game) for PC, the final battle is against a duplicate of the Enterprise, but tricked out with plasma torpedoes in addition to the normal weapons and escorted by two pirate vessels. It's easily the hardest part of the entire game.
- The final boss in the NES version of Double Dragon is Billy Lee's (the player character) twin brother Jimmy, who has all the same moves as the player and more health. This is actually a carry-over from the arcade version, in which the game forced both players to fight each other at the end if they defeat Machine Gun Willy together (Jimmy Lee was originally the Player 2 character in the arcade version).
- The NES version also has a one-on-one Versus Mode where you could compete against the computer or another player as one of six characters (Billy Lee and five enemies from the main game). For some strange reason, the developers decided to use larger sprites for all the characters in Versus Mode (except for Abobo, who uses the same sprites from the main game and looks oddly proportioned compared to the other Versus Mode characters) and as a result, only same character matches are allowed. When Billy is chosen, the Player 2 variant will be colored like Jimmy (red clothes and blond hair).
- In Double Dragon II (both, arcade and NES versions), the player must fight against a clone of their character in the enemy's hideout. If there's a second player present, then there will be two clones instead of one (one for each Lee brother). The clones have almost all of the same moves as the player, along with the ability to throw projectiles and possess the player from the inside to drain their health. The clones are the final bosses in the arcade version and the penultimate bosses in the NES one.
- Jeff, an enemy character who appeared in the first two arcade games (and the Sega Master System version of the first), narrowly averts this by being a head-swap of the Lee Brothers and not a full clone. However, when Jeff returned in Super Double Dragon for the SNES, he was made into a complete palette swap of Billy Lee with tanned skin and a green outfit. Oddly enough, Jimmy, who was a palette swap of Billy up to this point, was made into a head swap in the SNES game.
- In Streets of Rage 3, the third boss is a robotic duplicate of Axel Stone named Break. He looks exactly like Axel, only with blue gloves to distinguish him.
- In the original game, Onihime and Yasha (aka Mona and Lisa), the twin bosses at the end of Round 5, were palette swaps of Blaze. However, when they returned in the third game, they were given new sprites.
- In Undercover Cops, the player must fight against clones of all three heroes before fighting the final boss.
- The trope name comes from the Mortal Kombat series of video games. In the original Mortal Kombat, you fought a clone of the character you selected before going on to the two-on-one Endurance Matches. The early-90s Mortal Kombat comic referenced this, with the queen of a warrior tribe who just happened to look and dress like Sonya.
- And, of course, Shang Tsung could turn the fight into a Mirror Match by transforming.
- However, the earliest incarnation of this trope predates Mortal Kombat by at least seven years. Ultima IV had the player's party fight evil opposites near the end of the game; there may be earlier examples.
- Street Fighter II: Champion Edition was produced largely to allow this sort of match - the original Street Fighter II didn't allow for mirror matches (except for the SNES version shown above, which featured a code that could be inputted when the game started).
- The Street Fighter II manga by Masaomi Kanzaki had a story arc where the four main Street Fighters (Ryu, Ken, Chun-Li, and Guile) had to team up with the Four Shadaloo Devas (Bison, Sagat, Vega, and Balrog) in order to defeat their evil clones.
- Gouki/Akuma in Super Street Fighter II Turbo actually had an alternate ending if he defeated himself as the True Final Boss. Unfortunately the text that explained the ending was cut from the American version - basically he fought his own darkness and won.
- Later games actually gave some characters special intro animations when this happens, usually interacting with their clone before getting into fight position.
- Guilty Gear has a great deal of fun with this sort of match - not only does it have two themes to call its own ("Fatal Duel" from GGX and "Nothing Out of the Ordinary"), the after-match quote from the winner hangs a lampshade on it, as the character chastises their opponent for impersonating them. Some versions even have different voice samples for the second player in a mirror match.
- Similarly, Melty Blood characters fighting themselves will generally comment on it after the match ("Geez, you're just a fake, but your hair is so pretty...!"). To say nothing of the many, many Doppelgänger characters in the series.
- An interesting Mirror Match happens in Guilty Gear X2 in Axl Low's story mode. He fights a version of himself from the future. The interesting thing is that unlike most fighting game mirror matches, both combatants look exactly the same, including colour scheme (sometimes making it hard to tell who is who) yet future Axl is using Axl's EX moveset and is invulnerable to normal attacks. Turns out future Axl traveled back in time just to give his past self a pep talk...and a beating apparently.
- This is also lampshaded in Capcom's Marvel fighting games. In Marvel Super Heroes, Spider-Man's win quote is even: "Just what I needed, another clone!" (As if The Clone Saga wasn't enough.)
- And taken even further in Tatsunoko vs. Capcom with Yatterman-1. To avoid players from questioning why would they be summoning the same giant sentient robot dog, the default Yatterman palette summons Yatterwan (said giant sentient robot dog) whereas the alternate color scheme calls out Yatterpelican (a giant sentient robot pelican). This has been taken down in the US version though, as it poses unfairness as Yatterpelican has a higher angle for the flame attack.
- Again in Tatsunoko vs. Capcom, Gold Lightan has a quirk when choosing his alternate palette. Aside from turning silver, his name changes to Silver Lightan, and all of his voiced attacks with "gold" are changed with "silver". Yes, that means he shouts "SILVER LIGHTAAAAAAAAAAAAN!"
- In MODOK vs. MODOK matches, whoever wins will make a comment about needing to remember to lobotomise his clones in the future.
- Guilty Gear's Spiritual Successor, BlazBlue, also has a dedicated theme for these: "Blood Pain".
- And in SVC Chaos: SNK vs. Capcom, every single possible character matchup has its own dialogue. Right down to said Mirror Matches. Kyo even references the rampant clones he had running around during the NESTS saga.
- In Samurai Shodown, some characters have special pre-battle dialogue when entered in a Mirror Match; for example, Ukyo Tachibana remarks "Hey! That's my face. You're meat, beanhead."
- Since the very first game, Nakoruru's 2P color was hinted at being an alternate personality of her by giving her win-portrait (and sometimes, official art of it) a malicious smile. This was used in her Bust/Rasetsu versions since the third game, but while those would eventually spawn a different character named Rera, the "purple" Nakoruru would still survive as Nakoruru's alter ego, who would be made into a secret character for Samurai Shodown 6.
- The third game in the series created alternate versions of each character, giving them different special moves to expand the gameplay, as well as a shape-shifting mid-boss who would transform into you for a mirror-match. However, mirror matches against the CPU were handled very poorly: Not only would the mid-boss transform into the exact same version of the character you were using; you were required to also beat your actual alter ego...who would be the same version as you and the mid-boss. Then, in the fourth game, each character has a fixed set of enemies he/she can fight, so it actually averts CPU mirror matches; unless you were using Amakusa, who returns as a boss and in fact uses the opposite style you picked for your character.
- The same applies to One Must Fall: 2097, in Story mode for all playable characters (in Tournament mode, you create your own pilot, who has no doubles in the tournaments which come with the game). All characters notice what's happened (it isn't played as impersonation) and seem to consider meeting themselves normal. Example from Milano: "When I think about you.../ ...I kick myself..."
- The best part? Angel vs. Angel is a plot point if you know her backstory.
- The King of Fighters games play with this trope as well. In KOF 2003, Terry Bogard comments that "I just changed my image and I already got impersonators!" if he beats the Fatal Fury Team.
- In KOF'97, since the New Face Team is both a regular entry and a boss team they're given dialogue between them and their alter-egos that state that they're clones of the CPU characters.
- In KOF XI, having Kyo win a mirror match has him, much like Spidey before him, take the mickey out of this:
Kyo: Just how many clones of me are left? I could make a baseball team out of me!
- Lampshaded in Super Smash Bros. Brawl when Solid Snake calls Colonel Campbell on his codec during one of these, and both Snake and Campbell are puzzled about where the other Snake came from. Snake being a clone, Campbell brings up the possibility of the other Snake also being a clone, but ultimately decide not to let it bug them too much.
- Note, however, that Snake senses the other Snake to be an imperfect clone because his fighting style is different.
- Also used in the end part of the subspace emissary where Tabu takes the pieces of the world the bombs detonated in and puts them together to make a maze, which includes boss characters already fought and a rainbow colored version of all the playable characters.
- In the old Neo Geo fighting game Kabuki Klash, the loser of a Mirror Match was shown to actually be a Kitsune (if you're playing a female character) or a Tanuki (if male) imitating the winner on the victory screen. (Where they usually slump over or kneel in defeat, a puff of smoke reveals a little kitsune/tanuki instead.)
- Again from Neo Geo, the penultimate fight for every character in Waku Waku 7 is a shadowy clone of themselves.
- All three Art of Fighting games, but in Art of Fighting 2's story mode, the characters would have some funny dialogue to exchange pre-match in story mode.
- Interestingly most characters in Bleach: Shattered Blade do have special opening quotes for fighting themselves, although only a handful have special victory quotes where they dismiss the quality of their fake. The 2nd Player versions of the characters don't usually have any special quotes.
- The makers of Magical Battle Arena seem to think that normal Miror Matches are too wimpy. After all, why else would they sic five duplicates of your character at you for the obligatory Mirror Match stage?
- SoulCalibur 3 has these built into (almost?) every character's story mode. They appear to be the externalized representation of some internal conflict for the chosen character, and the story always moves on regardless of whether or not you win, albeit usually in a different direction.
- Dissidia Final Fantasy, of course, as a fighting game. The characters can have some interesting lines for their duplicates; ranging from a Mythology Gag (Cecil repeating his line before facing himself in his own game: "This is a fight for me and me alone."), to the utterly hilarious.
Kefka: (vs Kefka) Who's that handsome devil?!
- Cloud Strife got a serious mood whiplash with his mirror match quotes. His first was a somber "If I win, will my sins be forgiven?" and in Duodecim that got changed to "Not you again!" in a more humorous tone. This actually makes sense when you consider that Duodecim is a prequel, and in the story line of the prequel he was actually fighting for the side of Chaos.
- Dissidia 012 introduces a new type of battle piece in the Scenario 000 story mode, which pits every member of your party against an exact duplicate of themselves with the exact same moveset, abilities, equipment, and stats.
- In addition, Sephiroth faces another Sephiroth as an in-game representation of him committing suicide.
- Eternal Fighter Zero not only has standard mirror matches (complete with unique win quotes), but in Memorial, you can set up a match between Kanna and Misuzu. If you've played AIR, you know exactly what is wrong with this matchup.
- If you beat Real Bout Fatal Fury as Geese Howard (who is the final boss), your ending shows Billy having Face Doodling the word "nisemono" (impostor) on the defeated Geese's face.
- Again lampshaded in Melty Blood Re-Act by Ciel and Arcueid in Arcueid's story mode amongst others.
Arcueid: Look who it is. Are you the real one?
- Justified in Magical Girl Lyrical Nanoha A's Portable: The Battle of Aces, where the corrupted defence programme of the Book of Darkness creates "Memories", copies of the nine playable characters.
- Dead or Alive 2 has Kasumi facing off against her DOATEC-created clone, Kasumi Alpha. Other clones of Kasumi are visible in pods in the DOATEC lab stage.
- Breakers (and its sequel Breakers Revenge), a Neo-Geo fighting game by third-party developer Visco, had a unique approach for justifying the presence of mirror matches in the single-player mode. The computer-controlled clone of the player's character will have a different name tag and a unique palette used exclusively by the computer, implying that the clone character is actually a different fighter who uses the same fighting style.
- In the NES version of Teenage Mutant Ninja Turtles Tournament Fighters, this feature is available for every fighter except Hothead (a humanoid dragon based on the Warrior Dragon from the comics). The game claims that "The Dragon Spirit [inhabiting Hothead] would never allow such a thing," but in reality, the game's memory won't allow such a thing. If you use a Game Mod to do it anyway, it will cause massive flickering in the sprites.
- In addition to the usual version of this trope, several characters in Kinnikuman: Muscle Fight can face off against counterparts from further along in the canon timeline. Kinnikuman Big Body even has a special intro if he's facing against himself. As it turns out, one of the Kinnikuman Big Bodies is the God of Brute Strength and the other is Strongman.
- The multiplayer of Metroid Prime 2: Echoes, as described in the box art, is "Samus vs. Samus vs. Samus vs. Samus!".
- Also, arguably the SA-X in Metroid Fusion.
- To say nothing of Dark Samus (Metroid Prime, revived by the Phazon taken from Samus) and shapeshifter Gandrayda who seems to like taking Samus's form a lot. It's safe to say that Samus has seen this trope quite a lot. Even in Super Smash Bros.. Brawl she has to deal with Doppelgangers...except that she doesn't have her own suit on and uses vastly different moves.
- Dynasty Warriors 3. The battle of Fan Castle is a fight between allied forces (Wu and Wei) and Shu forces (led by Guan Yu). If you set up a custom battle on this map, choose the Wu forces, and select your character to be Guan Yu, he will comment in the opening cutscene, "I am my own opponent? This will be difficult."
- Kingdom of Loathing claims to have this in the final quest, with the Mirror Class monster. You can't hit it either, and it blocks anything you do to it. How do you win while it whomps you? Hint, Revive Kills Zombie.
- In Guild Wars, one of the main quest chains has you fighting a mirror copy of yourself, only all of its stats are maxed, and even if you don't equip any skills, it's got a big sword to hit you with. Or a bow if you run away. Oh, and it's max-level, while you can reach it several levels below your own max. Solution? Equip skills that require a health sacrifice, or hexes that the enemy triggers by either spellcasting or attacking. Either way, the AI is stupid enough to kill itself for you.
- However,it must be noted that before the expansions came out, you could have only been able to change your secondary profession AFTER completing said mirror match, so unless you knew beforehand and picked necromancer as a secondary profession to gain access to health sacrifice skills? your Mirror match could have been much more difficult.How difficult your mirror match is is really dependent on what profession you chose. A warrior could have an easy time, whereas a healing monk player could tear his hair out in frustration.
- World of Warcraft has three instances of copying.
- The first is a quest in howling Fjord, in order to "purge your evil." You have to meditate until it manifests as a copy of your character, unfortunately, this one has no skills other than attacking you, which leads to a rather disappointing fight.
- The second is herald Vol'azj in the Old Kingdom, once during the fight (twice on heroic) he casts insanity on the party, causing shades of the party to spawn where they were standing and attack you, these do use abilities, but besides iconic class abilities, they generalize the images to what their class is good at (druids and priests will only heal, death knights will death grip, ect. ect.).
- The third is in Icecrown Citadel, the Val'kyr will summons shadow reflections of various raid members who use powerful abilities and need to be killed, a few of these would later become skills useable by players.
- One of the task forces in the late, lamented City of Heroes ended with the hero team facing shadow copies of themselves in City Hall. Somewhat averted in that you were not forced to fight your counterpart among them (and in fact, most people didn't).
- One of the clone arcs, possibly the City of Villains version, ended with you having to fight eight copies of yourself. At some point in both the heroic and villainous clone storylines you had to face off with a possibly superior copy of yourself at least once.
- Usually played straight in League of Legends, but ranked games (and custom if you want) use draft pick, effectively barring mirror matches. The game does you the favor of putting colored circles around most of the persistent AOE effects in order to differentiate the source, while some of them are virtually impossible to distinguish.
- In Kirby and The Amazing Mirror, the intro cutscene shows Meta Knight facing off against his mirror self (called Dark Meta Knight in the game). He is quickly defeated. Kirby's mirror self (known as Shadow Kirby in the game) appears occasionally as an enemy - defeating him will give Kirby a random powerup.
- In the Meta Knightmare mode of Kirby: Nightmare in Dream Land, Meta Knight fights a copy of himself at the end of Orange Ocean.
- All areas in Super Mario Sunshine include a mission where you have to chase Shadow Mario.
- Super Mario Galaxy pits you in races against Cosmic Mario for a star. Not quite a fight, but a match in terms of platforming capabilities (however, Luigi's duplicate is much smarter than Mario's).
- In certain missions in Super Mario Galaxy 2, Cosmic Clones of Mario will follow your route through a level and mimic your actions exactly until you accomplish some objective, at which point, they'll disintegrate and turn into star bits. You're usually okay if you keep moving and don't retrace your route, but if you make even the slightest slip, they'll most likely clobber you.
- Done once more for Super Mario 3D Land in the special worlds. You will have a shadow clone chase you around as it follows your movements. Depending on the level, the clone will vanish as you make a transition to the next part of the level (which the clone will pop up again as you start to move on) or you can snag a Star and smash into it to temporarily disable it. Most of the time, you will have to clear the level to finally stop the clone. The last few levels in the special worlds give a giant version of the clone, making it harder to dodge it.
- Mega Man sometimes must battle an exact copy of his own schematics. Given that he is an artificial construct, this is a fully Justified Trope application.
- Subverted in Mega Man Powered Up. If you play as a robot master, the boss of his stage will be "Mega Man?", a clone of Rock, not the master himself.
- Played straight later on in Wily's fortress.
- Interestingly enough, the copies of Mega Man, despite being exactly the same, are always easily defeated by the real deal. Guess there's just no counting for experience.
- Subverted in Mega Man Powered Up. If you play as a robot master, the boss of his stage will be "Mega Man?", a clone of Rock, not the master himself.
- The first Prince of Persia game had you face a literal mirror copy of yourself, released from a magic mirror you had leaped through earlier. He shares your health bar, mirrors every attack identically. The only way to defeat him is to sheathe your sword.
- The final boss battle of Mega Man Zero 3 is one of these, although the twist is that the boss isn't the copy, the hero is.
- Tomb Raider also uses Mirror Matches, but in just a few games. In the first Tomb Raider and in the Anniversary remake, there is a skinless creature in the 2nd to last Atlantis level that has the shape of Lara Croft. The clone moves the same way Lara does and firing your guns at it hurts you, as well as the creature, so if Lara dies, the creature would too. The creature was really a puzzle where you had to trick it into falling into a trapdoor with lava below in order to move on to the next area. One level in Tomb Raider: The Last Revelation has a gold statue of Lara that hurts you if you fire your guns at it (why Lara actually aims at the thing is a mystery). Some enemies in the room actually attack the gold copy of Lara, causing harm to the real Lara.
- Sonic the Fighters deals with this situation in an interesting way: If two players chose the same character, a special cutscene is shown at the beginning of the battle where Dr. Eggman flies in and shoots a ray at the first player, creating a black and white clone which is the second player.
- In Sonic Battle, if more than one of the same character is selected in battle mode, each character except the original will become a version of Emerl with that character's moves and voices.
- Bad/Dark Rayman from the final level of Rayman, Mr. Dark's Dare. An evil double of Rayman, Dark Rayman would literally do everything Rayman did, essentially copying the player's progress with perfect precision, albeit lagging behind by a second or two. If he touches you, you will die instantly and lose a life. Since he's invincible to any of Rayman's attacks, you are forced to keep moving throughout the entire level without allowing him to come into contact with Rayman. Successfully reaching the end of the level kills Dark Rayman, allowing you to move on.
- In Shadow the Hedgehog, the two-player mode has each player controlling a clone of Shadow, with Player One as the most convincing copy.
- In Vexx, some of the Wraithheart missions involve playing minigames against three clones/dark versions of Vexx, referred to as Vexx's "inner demons" in the game. The clones can be attacked and even knocked out of the arena (but they reappear a few seconds later), but only truly die when the original Vexx wins the minigame.
- In Crisis Core: Final Fantasy VII, one of the Digital Mind Wave cutscenes shows Zack battling a simulation of his recorded data from last month's training, which appears as a clone of himself. The two are evenly matched - which is a bad sign, as it shows that Zack hasn't improved at all since last month.
- Paper Mario has enemies that can imitate Mario or his current partner. The second game even goes as far as a boss called Doopliss fooling his partners, and the player, into thinking that he's the real Mario.
- The third time you fight Doopliss, in the second battle with the Shadow Sirens, he can turn into Mario or his partner at any point in the battle.
- Super Paper Mario's Bonus Boss and one of the hardest bosses in the game which comes after a Bonus Level AND a Marathon Level is Shadoo, who is the dark form of every playable character in the game. Also apparently he can hurt you by walking into you while you can't despite being just a copy of you
- Belome, a Recurring Boss in Super Mario RPG, is an odd-looking statue come to life. Turns out being petrified builds up quite an appetite. The second time you fight him, he will periodically swallow one of your characters and spit them out, commenting on their taste and releasing a clone. The copies have their own stats, but use "evil" versions of your techs --while Mario can toss fireballs, his copy can cause a flaming meteor to drop from the sky.
- In the second expansion of the game Neverwinter Nights, Hordes of the Underdark, the player experiences a Mirror Match after looking in an actual magic mirror. However, the player also has henchmen, which tips the odds significantly in his or her favor.
- It's even easier if you unequip your weapons first. The mirror opponent only fights with what you had equipped at the time you looked in the mirror, so you can re-equip your weapon while the mirror opponent can only fight with their fists.
- If a player visits Umbra in SaGa Frontier, their trip ends with a Mirror Match between their first party and their first party's shadows.
- Secret of Evermore uses this several times throughout the game. Firstly the player fights 3 different copies of himself, after which another character confusedly remarks "Wow, according to my calculations, you're at least three times stronger than yourself!". Secondly, as part of the final boss battle you must fight another clone of yourself and the computer-controlled dog that has been following you throughout the game. However, what makes it interesting is that while the clone of the player can be taken out in one shot (he's no stronger than the clones from before), the clone of the Dog has roughly 10,000 HP.
- Although different characters, the duels between Luke and Asch in Tales of the Abyss otherwise fit this. Although Asch knows several spells Luke doesn't, they otherwise fight exactly the same, as they learned to fight from the same teacher. Not to mention that Luke is a clone of Asch.
- As part of a test, one of the boss fights in Secret of Mana is against the Shadow Xs, dark-colored versions of the three main characters.
- In Pokémon, Ditto and Mew have the move Transform, which will allow them to turn into an exact copy of the enemy Pokémon, and have all the same moves and type. But it doesn't get any stronger, meaning the original will usually win.
- A true exercise in futility is Ditto vs Ditto. They will continually be transforming into...a Ditto with 5 PP (Power Points) in Transform. Like pitting two Metapod against each other, but it can never end. (The aforementioned Metapod fight would, because they would eventually run out of PP and struggle each other/themselves to a knockout.) The mechanics of the move Transform were changed in Pokémon Gold and Silver (from Generation II onwards, it is not possible to Transform into a Pokémon that is the transformation of another Pokémon), specifically to prevent such an endless battle from occuring.
- It's also not unusual for simply the same species to be fighting on each side. However, true mirror matches (with the exact same stats and moveset) are generally only happening in the multiplayer environment.
- And the IV system (which means the chance of two Pokémon having exactly equal stats one in hundreds of millions) actually makes it almost impossible to have a perfect mirror match, especially since a Pokémon's statistics are also determined by natures and Effort Values. Further variation of each Pokémon comes in the form of differing movesets, form variations, abilities, and held items.
- The main quest of The Elder Scrolls IV: Shivering Isles features one of these. You fight a (literal) shadow copy of yourself, which has all your items, powers, and skills—oh, and a big, scary sword.
- With a bit of messing around with AI and status effects, the player can make someone clone them. The only downside is that it only lasts for around a minute before disappearing.
- This was an engine feature implemented for Morrowind. Because of a game-crashing bug when modders tried to use it, it was forgotten until it was used again in Shivering, and now appears to be fixed.
- Played somewhat straight in Final Fantasy IX, where one dungeon in the latter half of the game features actual mirrors that must be confronted, each one producing a duplicate of one of the playable characters, though not necessarily one that's actually in the active party. If the mirror character actually is duplicating someone in the party at the time, that party member receives a one-hit kill before the party can take any action (unfortunately, resurrecting that character during the fight will only cause another immediate one-hit kill from the mirror monster).
- On the bright side, each mirror-monster will spawn up to three doppelgangers per battle. Defeating them grants lots of experience - you may find yourself enjoying the company for a while.
- Graal The Adventure used to have a quest where the final boss was a mirror. The boss within would mirror your moves exactly. It didn't LEAVE the mirror, making it rather difficult to hit; but bombs could be thrown over the line between worlds...
- Wild ARMs: Alter Code F features enemies called Doppelgangers who imitate a party member. They're just normal Mooks though. They also appear in Wild ARMs XF and will have all of the special abilities of the copied character's special class.
- In Chrono Trigger DS, the Dimensional Vortex contains the Crimson Shade and Alabaster Shade, mirror opposites of Lucca and Marle, respectively. They use the same basic skills, boosted to twice their power.
- Crono himself gets his own Shade, too. Interestingly enough, the doppelgangers' moves are renamed. (Luminaire becomes Scintillation, Cleave becomes Rend).
- The other Shades have the same kind of renaming. (Ice II becomes Icefall, Cure 2 becomes Recuperate, Flare becomes Explosion, etc.)
- Kingdom Hearts:
- Kingdom Hearts II has, at one point, a cutscene version of one of these, featuring a Nobody versus their major-character counterpart. It could've played out like a Duel Boss, except...well...it is a cutscene. At the end, said Nobody said he had a good Somebody, and he was glad to get to meet him. The fight actually is a Duel Boss in Kingdom Hearts II: Final Mix+.
- Then, in Kingdom Hearts: Birth By Sleep, Terra's final boss is against his own body, with several identical moves. This is best overcome by blocking and countering all attacks directed at you. Also, Ven's final boss is Vanitas - the other half of his heart. This trope only really comes into play during the second half of the fight, though; up until then, Vanitas doesn't fight like Ven at all. And interestingly, it's Ven copying Vanitas' technique in the second half, not the other way around as you'd expect.
- This happened in the first game, too, with the Anti-Sora boss fight in Neverland. Shadow Sora Heartless also appear as normal enemies in the same world. Though not strictly a mirror match, the fight against possessed Riku in Hollow Bastion feels like this, due to his similar fighting style and using dark versions of Sora's moves (such as Strike Raid).
- Kingdom Hearts Re:coded features a battle against the data version of Sora's Heartless, which has transformed into an incredibly powerful Darkside thanks to absorbing the data of the other Heartless in the journal. During the fight (which is a Sequential Boss), the second, third and fourth stages have it take the form of Anti-Sora, which fights almost identically to Data-Sora.
- In the prologue of Kingdom Hearts II, one of the Seven Wonders of Twilight Town has Roxas battle a shadowy version of himself, which comes out of his reflection in the waterfall.
- In the Reverse/Rebirth mode of Kingdom Hearts Chain of Memories, Riku battles the Riku Replica multiple times.
- In the Mission Mode of Kingdom Hearts 358 Days Over 2, it is possible to make Xion, Saïx and Riku battle "Anti-" versions of themselves, which appear as shadow versions of the character with glowing yellow eyes (like Heartless). (Incidentally, you fight the "Anti-" version of the character no matter which character you choose for the mission, with the exception of Xion, though the Xion fight doesn't really feel like a Mirror Match since the boss is in a different form to the player character).
- In Final Fantasy IV, when Cecil changes classes from Dark Knight to Paladin, his Dark Knight self walks out of a mirrored wall and attacks him. As with Prince of Persia above, you're supposed to stop attacking it, letting it fade away.
- More accurately, you're actually letting him kill himself. The only attack he uses is Darkness/Dark Wave, which deals damage to the user.
- In The World Ends With You, the kitsune-style noise (Psychedelifox, Ambiefox, and the like) can shape-shift into other forms, usually other Noise. If they get enough tails, they can shapeshift into Neku wearing a kitsune mask, and attack you with a set pool of psychs Neku is able to equip (though not necessarily what he currently has equipped).
- .hack//G.U. has this in the form of a Boss in Mook Clothing, the Doppelganger. He appears whenever you've stayed on an overworld map for too long, and is always 8 levels above you until you hit the level cap of the game (of which doing so turns him into a straight up Mook), and has a unique weapon that mimics, you guessed it, protagonist Haseo's weapon that's out at the time. This means that if you have the scythe out and he finds you . . . Oh Crap. The fact that the game has a driving, terrifying synth theme for him that gets louder as he gets closer, does not help things any.
- Fail to answer a sphinx' riddle correctly in Heroes of Might and Magic 5, and this will be your penalty—i.e. you have to fight an army structured EXACTLY as yours with the same creatures and led by the same hero with the same level, skills and items.
- In Dragon Age there's a test during the Gauntlet in The Urn of Sacred Ashes Quest that has each party member, including the player character, face an invisible version of themselves, complete with names hovering above them and matching voices (for shouting as you kill them)
- A rather interesting take is down in an early PlayStation 2 game and adaptation of Orphen called Scion of Sorcery where Orphen, Majic and Zeus are forced to fight against one. While its default form is that of a grayed out and dusty-looking version of Orphen with yellow boots, it can freely change into either of the party members. While it barely ever attacks, attacking it while it impersonates any one of you will result a significant amount of mirror damage dealt to your party but the person being imitated will receive the brunt of it and when it assumes its default form, it'll put up a barrier before launching a projectile. Reflecting the projectile with the right spell (Armor of Purity) will cause it to transform into a lizard man where it can safely be whacked on.
- Monster Girl Quest Paradox allows you to recruit every enemy, so this trope turns up whenever you have a generic enemy confront their random encounter version. Party members also carry over to New Game Plus, so this can happen even for unique named characters. Many of the latter have special dialogue when fighting against themselves.
- Lampshaded and occasionally justified in Touhou Hisotensoku and Scarlet Weather Rhapsody, during arcade or vs mode, if the player wins a mirror match, the characters will say something akin to: "Mirror-image training completed". Marisa even says "I'm winning 101 matches out of 100 in image training!" Considering that this is Gensokyo, people creating clones of themselves for danmaku training shouldn't come of as much of a surprise.
- Similarly, this is possible in the versus shooters, Phantasmagoria of Dim. Dream and Phantasmagoria of Flower View. Actually part of the plot in Dim. Dream, since the bosses don't change even if you're playing as them. Apparently Chiyuri has a Gensoukyou counterpart, and Yumemi got cloned by a device on the ship.
- This can also happen, to an extent, in Imperishable Night's practice mode. In the story mode's fourth stage, you fight either Reimu or Marisa, and if you chose one of those two as your player character, you fight the other one. In practice mode, you can fight either of them with any character, including themselves. And similarly, Spellcard Practice can be done by any character, and includes bonus spellcards by playable characters.
- One of Shikieiki's spellcards in Shoot the Bullet invokes this, forcing Aya to fight her reflection/clone.
- In the less-known PlayStation game Silent Bomber, the fight with Benoit feels like this, as Benoit has exactly the same moves and equipment as the main character.
- Mario Golf allows this, but the sequel does not. Mario Tennis only allows it in Special Games (e.g. short match) but not in the main game. This is problematic as every character plays differently, especially in the second Golf, where each character has their own power\accuracy mix, so the best players will probably all want the same one or two hard-hitters.
- After unlocking Pete in Backyard Skateboarding, you can play as him in the Boardwalk; the boss challenge involves racing Pete, so you're racing yourself.
- One of the bosses for Silent Hill 3 is Alessa, a carbon copy of the protagonist Heather, only decaying and bloody.
- Part of the lead-up to the final boss in the NES game Sweet Home features a number of one-on-one fights against mirrors of your own five-member party. Since there are two or three paths to the final boss platform, which path you take indicates which party member double(s) you have to fight.
- In Eight Bit Theater, Black Mage encounters a copy of himself, representing his inner darkness and such, in the Castle of Ordeals. This was because the only thing evil enough to match Black Mage is Black Mage.
- Parodied, somewhat, when Fighter splits up the Light Warriors, Dark Warriors, and Other Warriors into new teams. Fighter places himself on every team (in one case, three times). Thief convinces Fighter that he's picked a "random" representative from each team to have a fight to the death (naturally, he picked each team's Fighter), leaving a very confused Fighter fighting "himself"... but there's still really only one of him, so he stoically waits for an attack to counter, leaving him frozen in place for a while.
- Goblins has a variation; the dungeon the Maze of Many forms a link between all the dimensions in the multiverse,and pits adventuring parties against versions of themselves from all possible realities. It's not a straight mirror match, though, since there are subtle differences between each individual, depending on which reality they originated in.
- In Order of the Stick, the main party's nemeses are a (mostly) mirrored version of themselves. The leader of the evil party is even the Evil Twin of the leader of the good party, complete with goatee. Even the leaders' names are reverse anagrams (Elan/Nale).
- Justice League Unlimited episode "Divided We Fall" Luthor-Brainiac recreated the Justice Lords (and a very Reverse-Flash-looking evil Flash) for the original founders of the Justice League to fight. They stopped them by going up against different copies, instead of their counterparts.
- The Flash beat his evil counterpart on his lonesome. Dude knows how to deal with his issues. (That's because he is the only sane one of them. He just got super powers and decided to help people.)
- IIRC,[please verify] Batman beat his duplicate as well.
- Also played with in the episode "Fearful Symmetry": As Supergirl battles her Evil Counterpart Galetaea, the Clothing Damage of their costumes starts to make them mirror the other's...
- An episode of The Powerpuff Girls has a trio of criminals who decided to disguise as the girls to rob banks. It works, even though they are tall, ill-mannered men with weird dresses and huge theme-park-disguise powerpuff girls heads that you could see their beards through. Even more so, when the girls finally appear to fight them, both teams are attacking one another at random, until Blossom screams "Enough! Everybody, fight only your double!", and everybody accepts, even the non-powered villains.
- In Teen Titans the Titans faced off against evil versions of themselves whipped up by Trigon who was starting to find their attacks against him annoying. Because their evil counterparts had the exact same abilities as the originals, the heroes are only able to win by switching opponents.
- Things went a little differently in the comic book version of the story. All the Titans except Raven (who was turned into a demon and on her father's side), Jericho (who was badly injured), and Lilith (a wild card) were forced into nightmare scenes by Trigon where they had to fight their evil clones (Cyborg's copy was fully human but just as strong, stole his girlfriend, and made the disabled kids Cyborg befriended turn against him). All of them, even Nightwing and Beast Boy, killed their copies and their souls were forfeit to Trigon as a result. Unfortunately for Trigon, this didn't convert them to his side as intended and simply made their methods more ruthless. They killed Raven, which turned out to be part of Lilith and the goddess Azar's plan to stop Trigon (Raven got better...eventually).
- In The Simpsons episode "The Computer Wore Menace Shoes", Homer fights an actor impersonating him. Homer wins by fighting dirty. "If I know me, he won't like being kicked in the crotch!"
- For a city- (or possibly small-town-) scale Mirror Match, see the episode "Lemon of Troy".
- In an episode of Recess, the main characters have to play a kickball match against a Similar Squad from another school. The similar tactics of both teams keep the game at a stalemate. In the end, the winners are both teams. When the feud between brothers Peter and Paul Prickly devolves into a childish brawl, T.J.'s group and C.J.'s group realize they're being pitted against each other as part of an ego-measuring contest. So all the kids do the grown-up thing and decide to play together somewhere else.
- The whole Saturday family has almost exact mirror matches from an alternate universe.
- In Batman: The Brave And The Bold, Batman faces his evil Mirror Universe counterpart, Owlman. He wins by turning off the lights, causing Owlman to don night-vison goggles, then quickly lighting a flare to blind him.
- In the Futurama episode "The Farnsworth Parabox", the gang enter an Alternate Universe and the two Leelas start fighting. But because their moves are identical, they both knock each other out after the first hit.
Prof. Farnsworth: Now, now. Perfectly symmetrical violence never solved anything.
- In an episode of the Aladdin TV series, Chaos makes an evil copy of Aladdin. The hero wins by using his evil counterpart's lamp to wish him away. The "evil" Aladdin didn't free his genie as the real Aladdin did.
- Big the Budo, Brocken Jr., Kinnikuman, Perfect Choujin Neptuneman, and Ramenman
- Neptune King for Big the Budo, Kinniku Suguru for Kinnikuman, Justice Choujin Neptuneman and The Samurai for Perfect Choujin Neptuneman, and Anime Ramenman and Mongolman for Brutal Ramenman
