History Main / MirrorBoss

*** The [[EliteMooks Joys]] are a minor version of this. They're much weaker than Bayonetta, but mimic a lot of her moves.
*** [[MarathonLevel Angel Slayer]] has [[spoiler:Bayonetta herself as the ultimate Mirror Match]], who can use the exact same techniques and weapons she can, just while dealing much higher damage.

** ''VideoGame/NierAutomata'' has A2, fellow [=YoRHa=] android like protagonist 2B who thus fights with similar techniques. If you decide to play [[spoiler:as 9S in some paths, he ends up running into multiple 2B clones, basically Mirror WolfpackBoss]]. Taken further in [[spoiler:Ending C and D, where 9S and A2 have one last fight before the ending; Fighting A2 will be mostly similar to her earlier fight, while fighting 9S will have you try to counter his hacking, just as how you've been using his hacking while playing as him]].

* The ''VideoGame/{{Kirby}}'' series's King Dedede can swallow and spit out enemies, as well as float/fly, just like Kirby can. He isn't able to copy any abilities, though. It's worth pointing out that Dedede actually learned how to do those things by observing Kirby ''just'' so that he could use them against him.

** [[AvertedTrope Averted]] in ''VideoGame/MegaManX6''. In order to unlock Zero as a playable character, X must first destroy the Nightmare Zero, a mysterious duplicate of the original. Because of this, it is impossible to fight Nightmare Zero while playing as the real Zero (though hacking the game can get around this).

* ''Videogame/PrinceOfPersia1'' has a literal version: Early on in the game, the player is forced to leap through a mirror. Though the player passes through, a duplicate appears from the other side of the mirror and runs away. This doppelganger reappears at a few points throughout the game to grief the player, and then for a final showdown near the end, where the doppelganger will mimic the player's attacks and defenses, making it impossible to defeat him in combat. [[spoiler:The only way to beat him is to [[SheatheYourSword put away your sword]]. The doppelganger will follow suit, allowing you to walk into him and absorb him back into yourself]]

* Mecha-Turtle in ''VideoGame/TeenageMutantNinjaTurtles1989''.

* [[spoiler:Along the way to finding the Urn of Sacred Ashes]] in ''VideoGame/DragonAgeOrigins'', a ghostly version of your current party attacks you, using all of their current attacks, abilities, etc.
** It's also worth noting that if you have one or two mages in your party, or if your PC is a mage, [[ThatOneBoss this fight can be incredibly difficult.]]

* In ''VideoGame/{{Touhou}} Project'' 9.5, ''Shoot the Bullet'', this is Eiki Shiki's last spellcard, "Cleansed Crystal Judgment": a magic mirror that produces a clone of the protagonist that uses her attacks.
** The reflection fights like Aya did in ''the previous game'', while she's using completely different mechanics here. The Aya/Hatate fights in ''Double Spoiler'' are much closer to the trope, putting you up against a boss that uses photography, although the game is inherently asymmetric.

* At the end of ''VideoGame/{{Extermination}}'', after defeating its giant monster form, the Alien Lifeform transforms into a copy of your character; basically a soldier with an assault rifle.

** ''VideoGame/TheLegendOfZeldaSpiritTracks'': He shows up once more as a {{Superboss}} at the very end of the most difficult BossRush challenge of the game, and not only replicates Link's sword skills but also his usage of bombs and arrows.

* ''VideoGame/{{Ultrakill}}'' has V2, a combat robot that looks identical to [[PlayerCharacter V1]] albeit painted red. Like V1, V2 possesses all of V1's movement techniques and uses the Piercer Revolver and Core Eject Shotgun. V2 returns for a rematch in the Greed layer, adding the Marksman Revolver and Overheat Nailgun to its arsenal. A secret in the Violence layer also has an encounter with [[spoiler:[[Creator/NewBloodInteractive Big Johninator]]]], who shares V2's movement and uses both the Malicious Railcannon and a generic version of the Rocket Launcher.

** The {{Superboss}} fight in the Armax Arsenal Arena is a fight against three waves of Shepard duplicates, using the six classes available to the player. Available if the players buy the mirror match combat set via a gold prize.

* ''VideoGame/{{Ultrakill}}'' has V2, a combat robot that looks identical to [[PlayerCharacter V1]] albeit painted red. Like V1, V2 possesses blinding mobility and even uses the same weapons that the player has unlocked up to that point.

* ''VideoGame/GravityCircuit'': [[spoiler:Nega, the [[LegacyCharacter original]] Gravity Circuit]], faces off against Kai in the first finale stage and uses the same basic moves as he does. As the fight progresses, he'll give himself buffs identical to three of Kai's equipment chips, and in the final phase of the fight he starts using three of the four basic Burst Techniques.

* In the ''Citadel'' DLC pack of ''VideoGame/MassEffect3'', the primary antagonist is [[spoiler:[[EvilTwin an evil clone of]] [[PlayerCharacter Shepard]]]]. They originally appear in a different set of armor, but when you actually fight them, they've stolen some of Shepard's N7 gear and inverted the default colors to complete the look. And whatever class you're playing as, they match. "That's creepy."
** The {{Superboss}} fight in the Armax Arsenal Arena is a fight against waves of Shepard duplicates, using the six classes available to the player.

** ''VideoGame/TheLegendOfZeldaOcarinaOfTime'': Taken very literally during his reappearance as a miniboss, where he would perfectly mimic every movement and attack the player made, like a mirror image… except if the player performed a stab, in which case Dark Link would jump on top of Link's sword and get a free hit.

* ''VideoGame/LegacyOfKain: Defiance'' closes its third act with a DuelBoss fight, pitting the two player characters against one another, first with Kain against Raziel, and then vice versa.

*** ''VideoGame/{{Bayonetta 2}}'' has the Masked Lumen, AKA [[spoiler:Balder]], who fights using Lumen Sage variations of Bayonetta's moves.

** Lady Maria shares many similarities with the above mentioned [[spoiler:Gehrman]], having massively increased mobility and damage compared to the player and powers up twice during the fight, can do ripostes and visceral attacks and has a unique weapon that can only be acquired after defeating her (though getting hers involved dealing with [[ThatOneSidequest tough foes]] instead of just buying it) all of which is only fitting since [[spoiler:Maria was Gehrman's first and only pupil]].
** The final boss of ''The Old Hunters'', the [[spoiler:[[MonsterIsAMommy Orphan of Kos]]]], fights like the player with their unique traits exaggerated to ridiculous degrees, having unparalleled mobility that lets them leap across huge distances in a flash while having extremely fast, far-reaching attacks with their TransformingWeapon on top of having access to a slew of potent ranged attacks. And all of it is cranked [[ExaggeratedTrope Up to Eleven]] during the second phase of the fight, where its ranged attacks are amplified even further and the camera ''has trouble keeping up with the boss'' due to the [[spoiler:Orphan of Kos]] being so mobile that every attack sends it careening across the arena. Fittingly for a boss that takes some of the player's strengths to ludicrous degrees, their biggest weakness is the one tool the player has that the boss doesn't: Ripostes.

* Kojiro in ''VideoGame/BraveFencerMusashi'', a child swords[[strike:man]]boy summoned by Princess Fillet using the same [[SummonEverymanHero Hero Summon]] spell that called Musashi… but instead of rescuing her, he decides to kidnap her to goad Musashi into a duel. Also, the final boss, [[spoiler:Dark Lumina fused with Kojiro]], uses elemental attacks from the same five elements as Musashi's scrolls as well as a sword combo.

* The Black Phantoms in ''VideoGame/DarkSouls'' are basically AI-controlled [[PlayerVersusPlayer Invaders]].

* ''VideoGame/JadeEmpire'' uses this quite successfully. While many boss encounters deal with 20 foot tall Golems, spirits gone bad, or groups of [[EliteMook Elite Mooks]], the final boss encounter is a [[DuelBoss one-on-one fight]] against someone who uses abilities very similar to your own. [[spoiler:Which makes sense; he taught them to you.]] This works as a strong display of the strategic depth that the game creates: that the final boss can be a character just like yourself, while still giving an entertaining, difficult-but-fair final confrontation. No weak points to aim at, nothing like that. The final boss blocks, attacks, dodges, heals, etc., all exactly like your character can. You must display mastery of your combat forms to stand a chance.

* In ''Videogame/{{Transistor}}'', the final boss [[spoiler:Royce]] uses a Transistor just like Red, meaning that not only does he use Functions as well as Turns, he also has Second Chances as well.

* ''VideoGame/SuperSmashBros for Nintendo 3DS/Wii U'' features this with [[spoiler:Master Core. After cycling through a number of [[EldritchAbomination bizarre shapes]], it forms a shadowy copy of your current character. This clone perfectly matches your custom moves, equipment, alternate costume, and even the appearance of your Mii if you're playing as one.]]

* Downplayed with ''Videogame/DoomEternal'''s [[BossInMookClothing Marauder]]. While these demonic knights don't have the exact capabilities of the [[PlayerCharacter Doom Slayer]], they run pretty fast, can NoSell anything with their [[LuckilyMyShieldWillProtectMe shield]], have a limited form of the VideoGameDashing that the Slayer has, and are ''very'' quick on the draw, making them a greater threat than anything else on the battlefield. This comparison gets further cemented by the Marauders' backstory: [[spoiler:during the [[GreatOffscreenWar Argenta Civil War]], Marauders slain in service to the [[BigBad Khan Maykr]] were [[BackFromTheDead brought back to life]] with the Divinity Machine, the same device that was originally used to imbue the Doom Slayer with his [[LightningBruiser superhuman speed and strength]].]]
* ''VideoGame/{{DUSK}}'' ends with a 1-on-1 deathmatch against the cult leader Jakob, who both uses some of the players weapons and moves around just like the player, AKA constant bunnyhopping. Not only that, you end up taking his place as the cult leader after defeating the true final boss [[spoiler:Nyarlathotep, voiced by the same person who voices Caleb from {{VideoGame/Blood}}, effectively making the fight a test to see whether you're "worthy" of being a badass FPS Protagonist]].

* In ''VideoGame/{{Genji}}'', the final trial in the Golden Temple of Shukenten involves Yoshitsune and Benkei facing a mirror clone of themselves. Literally, as the clone replicates every single movement exactly like a reflection, and can't even interact with the player, but using the special attack Kamui makes them attack for real, the only way to slay them and pass the test.

* The ''Franchise/{{Castlevania}}'' series has a recurring enemy, Doppelganger, who is a duplicate of whoever the hero of the game is. It first appeared in ''VideoGame/CastlevaniaIIIDraculasCurse'', where it would switch forms whenever you switched characters. The easiest way to beat him was to switch characters when right next to'em, hit'em once and repeat until he's dead: he'd be too busy changing forms to actually attack you. The ''Symphony'' version is interesting in it that it's the only boss that's susceptible to [[StatusEffects status effects]] and can thus be made harmless via using several normally useless swords that curse the enemy they hit.

* In ''Darkwing Duck Advance'', a hack of the ''[[VideoGame/DarkwingDuckCapcom Darkwing Duck]]'' LicensedGame for the [[UsefulNotes/NintendoEntertainmentSystem NES]], Negaduck serves as this to Darkwing, having his abilities to shoot and deflect enemy fire with his cape.

* Broken Vessel from ''VideoGame/{{Hollow Knight}}'' is a zombie version of the player's character with a similar style as the Knight: very mobile, mostly attacks with their nail, and sometimes uses spells/special attacks as opportunities present themselves. Hornet and [[spoiler:the original Hollow Knight]] fight in the same way, which makes sense considering [[spoiler:all of them are children of the Pale King, raised to be strong fighters]].

* ''Videogame/ShovelKnight'' has Black Knight, who looks and fights similar to the eponymous Shovel Knight, though he gains more unique moves each time you fight him.

* Interestingly subverted in ''VideoGame/BaldursGateTalesOfTheSwordCoast'', where you face a [[strike:Demonknight]] Death Knight and have the option of activating its Mirror of Reflection (which, it is initially implied, might be used against you). [[spoiler:Instead of conjuring a Mirror Boss, it instead conjures up weird distortions that attack everyone, as it's broken.]]

* The final battle of ''VideoGame/RingsOfPower'' on UsefulNotes/SegaGenesis is this, whereas your evil rival has gathered a party of adventurers with the exact same class composition as your own to fight you.

** [[spoiler:The boss of the Flopside Pit of 100 Trials, Shadoo, transforms into Dark versions of the four playable characters that use their special abilities to attack (except for Dark Mario, who uses [[DropTheHammer Cudge]]), each with 100 HP and 10 Attack (20 for Dark Bowser, mirroring Bowser's Attack being double Mario, Peach and Luigi's). His Dark Luigi form even resembles Mr. L.]]

** ''VideoGame/ZeldaIITheAdventureOfLink'' has him as the final boss, excelling at front swordplay (though without knowing the Up- and Downthrusts). Outside a quirky trick, defeating him requires exceptional sword skills.

** [[spoiler: Ganondorf]] at the end of ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'' fights Link in ways that are similar to him. Like Link, he can change weapons on the fly and uses the same types of weapons he uses (sword, spear, and a club). Should Link attempt to use his Flurry Rush on him or attack poorly, the boss will counter with a Perfect Dodge of his own with the same BulletTime effect to boot.

** ''VideoGame/StarTrekThe25thAnniversary'': The final boss is a copy of the ''Enterprise'' but with plasma cannons and two escorts that show up about a minute into the fight.

** The final boss of ''The Old Hunters'', the [[spoiler:[[MonsterIsAMommy Orphan of Kos]]]], fights like the player with their unique traits exaggerated to ridiculous degrees, having unparalleled mobility that lets them leap across huge distances in a flash while having extremely fast, far-reaching attacks with their TransformingWeapon on top of having access to a slew of potent ranged attacks. And all of it is [[ExaggeratedTrope Up to Eleven]] during the second phase of the fight, where its ranged attacks are amplified even further and the camera ''has trouble keeping up with the boss'' due to the [[spoiler:Orphan of Kos]] being so mobile that every attack sends it careening across the arena. Fittingly for a boss that takes some of the player's strengths to ludicrous degrees, their biggest weakness is the one tool the player has that the boss doesn't: Ripostes.

And all of it is [[UpToEleven cranked up to eleven]] during the second phase of the fight, where its ranged attacks are amplified even further and the camera ''has trouble keeping up with the boss'' due to the [[spoiler:Orphan of Kos]] being so mobile that every attack sends it careening across the arena. Fittingly for a boss that takes some of the player's strengths to ludicrous degrees, their biggest weakness is the one tool the player has that the boss doesn't: Ripostes.

** [[VideoGame/ScottPilgrim The game]] plays this trope straight by including Nega-Scott as a boss, though you don't have to play as Scott to face him. He ultimately subverts it by having attacks that the real Scott can never pull off.

* Metal Sonic in ''VideoGame/SonicTheHedgehogCD'', as well as many other Sonic robots built by Robotnik which may or may not be the same one remodeled. The first one appeared in ''VideoGame/SonicTheHedgehog2'', and was also the first boss in the series who wasn't Robotnik.
** Also see ''VideoGame/SonicAdventure2''. The whole game was replete with mirror bosses, having each of the characters fight their alternates on the other team. You basically have to fight each mirror boss twice, since they are the exact same regardless of which team you are playing on and both teams have to be completed in order to get the GoldenEnding.

** In ''VideoGame/{{Sonic Rush|Series}}'', Sonic fights Blaze, although some of the moves used by the AI character aren't available for the player, even when playing as that character. [[VideoGame/SonicTheHedgehog2006 The 2006 game]] also has Silver fight Sonic and Shadow. And the various fights against Sonic/Knuckles/Gamma (depending on who you're playing as) in the story modes of the first ''VideoGame/SonicAdventure''.

** Also, in ''VideoGame/SonicGenerations'', Shadow has all of the moves that Modern Sonic has... including Boost.

** The final boss, [[spoiler:Hades himself]]. Like Theseus, they use a spear as their weapon, and their spearwork during the first stage is similar to Zagreus using Varatha, including his normal attack and spin attack. The skulls they launches also inflict Boiling Blood upon you, the same as Zagreus's own bloodstone attack. [[spoiler: If you upgrade him with Extreme Measures 4, he gains a Raging Rush, like the Aspect of Achilles, teleporting to Gigaros after throwing it. He can also summon Cerberus as a companion]].

* ''VideoGame/{{Hades}}'': Theseus is a mix of this and serving as a FinalExamBoss for the Elysium section of the game. When he reaches half-health, his second phase involves starting to use a random Greater Call boon that Zagreus can be given. Additionally, his spear moves are very similar to Varatha, a weapon that the player can equip.
