[[VideoGame/{{Kirby}} Swallowing enemies whole]]. [[VideoGame/RocketKnightAdventures Flying around with a jetpack]]. [[Franchise/SuperMarioBros Or just jumping high]]. Video game heroes can have a wide variety of powers; they're fun to play around with, and they'll let you conquer just about any boss battle. You just need to dodge around its attacks and AttackItsWeakPoint for massive damage.

But what if those same powers were used against you?

A Mirror Boss, simply put, is a boss in a game whose abilities are the equivalent of the playable character's somehow. This doesn't have to be exact, and it's relative to what the other bosses tend to be like; if most of the game's bosses are gigantic, then just being the same size as the hero counts for a lot, but if everyone in the game is humanoid, a Mirror Boss will have a very similar fighting style.

Depending on how close the boss' abilities are to the hero's, there may have to be some form of [[TheComputerIsACheatingBastard "cheating"]] to insure that the boss is still a challenge. Giving them [[ContractualBossImmunity special immunities]] to things that would normally destroy the player, some SecretAIMoves to separate them from the hero, or just any general application of MyRulesAreNotYourRules to prevent the player from exploiting certain weaknesses.

If this boss isn't an EvilKnockoff of the hero, expect him or her to be a [[TheRival Rival]] or EvilCounterpart of the hero, and thus an important character in the game.

As you might expect, this is usually a form of DuelBoss.

'''Compare:'''
* EvilKnockoff, an evil copy of a hero.
* SuperpoweredMooks, regular enemies which have the same powers as the hero.
* ShadowArchetype and its many subtropes, which frequently overlap with this trope.

'''Contrast:'''
* BeatThemAtTheirOwnGame, which is when the protagonist's abilities are changed from normal to match the boss.
* MirrorMatch, which is when two players (or the AI) of a multiplayer game select the same character.
----
!!Examples

* The ''VideoGame/{{Kirby}}'' series's King Dedede can swallow and spit out enemies, as well as float/fly, just like Kirby can. But not copy abilities, though.
** While Meta Knight can't do what Kirby usually does, he fights just like a better version of Kirby with the sword... [[DuelBoss And often makes Kirby use a sword against him.]] [[spoiler:In some games, this is optional.]]
*** 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.
* Star Wolf in ''VideoGame/StarFox 64''. Unlike the large bosses encountered elsewhere in the game, Star Wolf comes down to your own level in an attempt to beat you at your own game, flying ultra-advanced fighter craft not unlike your own Arwings. And they seem to do a pretty good job of it, as each Star Wolf member seems to beat his Star Fox counterpart more often than not unless the player is there to save his teammates.
* The Blaze palette swapped enemies on the boat level in the first ''VideoGame/StreetsOfRage'' game. The robotic version of Axel in ''Streets of Rage 3''. Shiva from ''Streets of Rage 2'' and ''3'', as he possesses similar directional attacks, including a 360 degree defensive maneuver akin to the player's special move button, and a dashing attack.
* 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 [[StandardStatusEffects status effects]] and can thus be made harmless via using several normally useless swords that curse the enemy they hit.
** [[strike:Soleiyu]] Soleil Belmont from ''VideoGame/CastlevaniaIIBelmontsRevenge'' is the son of the main character, and was kidnapped and brainwashed by Dracula. He is the penultimate boss, wielding a whip like yours, and throwing swords that home in on you.
** [[spoiler:Richter Belmont]] in ''VideoGame/CastlevaniaSymphonyOfTheNight'' counts as well, since he uses a melee weapon and several of the same subweapons as Alucard, and avoids attacks by jumping and sliding.
** Hugh Baldwin from ''VideoGame/CastlevaniaCircleOfTheMoon'' wields a sword instead of a whip, but he uses your subweapons as well. He also has a variety of special sword techniques which are roughly similar to the DSS enhancements used by your character Nathan Graves.
** Maxim from ''VideoGame/CastlevaniaHarmonyOfDissonance'' is a bit less similar, since he uses a katana and a giant shuriken instead of your whip and subweapons, but overall he's close enough to count.
** Dmitrii Blinov from ''VideoGame/CastlevaniaChroniclesOfSorrow'' is a much closer match, since he has the power to duplicate any attack you use against him. And if that doesn't work, he'll just stab you with a knife. Since he'll stick to what he copies and then spams it liberally afterwards, he can either be ThatOneBoss or a BreatherBoss: for example, using any high-powered, MP-expensive, hard-to-avoid attack on him isn't too smart, as he has no MP to worry about, but since he only uses the souls at their level 1 strength, some of them are hilariously ineffective. The most notable of them is probably the Cave Troll soul, which causes the user to attack with an elongated tongue: however, since the level 1 version of it only has a range of a few pixels, he'll spend most of his time hopping around harmlessly sticking out his tongue at you.
*** If you never use a soul attack on him (for example, because you never caught on to the mimicry thing), he sticks exclusively to Malachi's soul -- which makes the fight quite a bit harder, since that attack is very hard to dodge.
*** Some souls are of course much funnier when you use them in practice. Yorick is one of the most hilarious primarily because Dmitri can't slide kick. So you can throw that soul at him (hitting him with it while he has Malachi active is the hard part). Once you got him though, he now has an attack that is puny, hard to hit with, and slow as hell. Have fun beating him up. And in this case, since Yorick's damage goes up to the triple digits if you kick it, you can kill him in a few hits while he is busy chucking skulls at you. However, giving him stuff like Amalaric Sniper or Abaddon is just asking for it.
*** Of course he WILL activate any secondary soul you have active if you activate one.
** Whip's Memory ([[spoiler:Richter Belmont]]) from ''VideoGame/CastlevaniaPortraitOfRuin'', a BonusBoss who [[DuelBoss is fought by Jonathan alone]] and has almost exactly the same style.
*** ''Portrait of Ruin'' also has a Mirror Boss in the form of the Doppelganger at the bottom of the Nest of Evil BonusDungeon
** Albus fills this role in ''VideoGame/CastlevaniaOrderOfEcclesia''. His guns are functionally similar to Shanoa's magic attacks, and he even has his own Glyph attack. On higher difficulty levels, he gains extra attacks which mirror Shanoa's elemental Glyphs exactly.
** Julius Belmont from ''VideoGame/CastlevaniaChroniclesOfSorrow''. He doesn't fight exactly like the player character, but he is human, and he fights ''exactly'' like a Belmont (duh), up to and including the classic subweapons.
* 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.
** Knuckles in ''VideoGame/Sonic3AndKnuckles'', if you're not playing as him. He's [[CurbStompBattle ridiculously easy to beat]], but Hidden Palace Zone is a BreatherLevel anyway. He is pretty much the same Knuckles you can play as, only with some HP instead of rings, a punch attack, and the ability to block by ducking. He even takes collision damage, though trying to walk into him will just get you punched. But you can stand in front of him and get Tails to walk into him from behind if playing as Sonic and Tails. Tails takes damage too, but he's invincible (in 2P mode). If Knuckles drops from a glide on your head, only he will take collision damage.
*** [[spoiler:The fake]] Knuckles in ''VideoGame/SonicAdvance'' works the same way.[[spoiler:.. until you hit it four times, at which point its skin explodes to reveal it as a robot capable of firing huge frickin' missiles.]]
** 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''.
** Half of the bosses in both ''VideoGame/SonicRivals'' games are battles with another playable character. Doubly so as every character plays exactly alike.
** Also, in ''VideoGame/SonicGenerations'', Shadow has all of the moves that Modern Sonic has... including Boost.
** In ''VideoGame/SonicHeroes'' the bosses of the City and Jungle areas are other MovesetClone playable characters as well, though they vary depending on who you're playing as (Team Sonic vs. Team Rose/Team Dark vs. Team Chaotix in the former and Team Sonic vs. Team Dark/Team Rose vs. Team Chaotix in the latter).
* Dark Link, who first appeared as the final boss of ''VideoGame/ZeldaIITheAdventureOfLink''; he reappeared in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' as a miniboss, where he had all of Link's sword skills and more.
** ''VideoGame/TheLegendOfZeldaFourSwordsAdventures'', as appropriate for a game about multiple Links, had "Shadow Link" as [[TheHeavy the primary antagonist]]. He appears in every level to harass Link using the same items you can collect in creative and destructive ways. He is also the boss of several levels.
** The BonusBoss of the GBA remake of ''VideoGame/TheLegendOfZeldaALinkToThePast'' is four copies of Link in different colored tunics as they are portrayed from the Four Swords game. Each Link uses different abilities that the player can use, such as the Hurricane Spin, using the Magic Cape to become invisible, and the ability to shoot sword beams.
** He shows up once more as a bonus boss in ''VideoGame/TheLegendOfZeldaSpiritTracks'' at the very end of the most difficult BossRush challenge of the game.
* This happens a total of three times in ''[[{{VideoGame/Persona2}} Persona 2]]''. In the first chapter, dubbed ''Innocent Sin'', you fight doppelgangers (or "shadow sides") individually in the Zodiac Temples. One of them, Yukino, is encountered in an earlier dungeon and is optional; in fact, the creation of Yukino's doppelganger hinges on the hero picking the wrong dialog tree at the dungeon's entrance. (Even if the party manages to defeat her, the fake is still victorious, driving the real Yukino to insanity.) In the sequel, ''Eternal Punshment'', the party must fight liquid metal clones of IS's main characters, and later, a straightforward boss rush against doppelgangers of themselves.
* Axle Gear from ''VideoGame/RocketKnightAdventures'', a member of the Black Knights who oppose the Rocket Knights which Sparkster is a member of. Like Sparkster, Axle Gear uses a rocket pack and a sword to battle. He also has the honor of being the only enemy to appear in all three games in the series (and ThatOneBoss in all three of them).
* Nelo Angelo from ''VideoGame/DevilMayCry'', a dark knight with the same swordfighting style as Dante, except that he hurls fireballs instead of using guns. He is also treated as a WorthyOpponent by Dante, [[spoiler:and turns out to be his twin brother Vergil]].
** Bolverk from ''DevilMayCry 2'' is often described as that game's equivalent of Nelo Angelo. He also has a connection to Dante (his father Sparda killed Bolverk's comrades, who were reincarnated as wolves) but it doesn't really come up in the plot.
** Vergil, Dante's [[CainAndAbel evil twin brother]] from ''DevilMayCry 3''. [[spoiler:Yes, the same one who becomes Nelo Angelo.]] He is one of the game's main antagonists, and is an equivalent of Dante in almost every way; not only does he have his own [[SuperMode Devil Trigger]] form, he also [[MegaManning turns Beowulf into a weapon]] like Dante does to the other bosses.
** Dante himself fills this role in ''DevilMayCry 4'' when he goes up against Nero. [[spoiler:Angelo Credo]] counts as well.
* Another Joe from ''VideoGame/ViewtifulJoe'' is portrayed as one of these, though he actually relies on the DoppelgangerAttack while warping around. A straighter example is the final boss, [[spoiler:Captain Blue]], who has VFX powers like Joe and can speed himself up with them, as well as having a similar moveset to Joe overall. Even moreso when you reach this boss as the final unlockable character, [[spoiler:Captain Blue]], at which point it's ''exactly'' identical... minus the random lightning bolts, of course.
* Ninetails from ''VideoGame/{{Okami}}''. A canine with godlike magical power, who wields a giant sword hovering over her back, and can even [[BeatThemAtTheirOwnGame interrupt Ammy's Celestial Brush with her own]]. The second stage of the fight with Oki has him transform into a wolf and wear his sword in the same way Amaterasu wears glaives.
** The [[BuffySpeak mirroriness]] gets cranked UpToEleven in the sequel, ''VideoGame/{{Okamiden}}''. The final boss is [[EvilKnockoff an evil version of Chibiterasu]], and literally comes out of a mirror. He has his own brush, like Ninetails, but the brush vs brush mechanics have been fine-tuned to the point where there is no difference in your abilities bar no matter how many secret brush techniques you picked up. Drawing a technique? He can cancel out with a line. He's drawing a technique? Cancel it with your own line! He even has an evil version of Sunrise that covers the arena in pitch-black darkness.
* Azel from ''VideoGame/GodHand'', who possesses the other God Hand and uses the same attacks and [[LimitBreak Roulette moves]] that Gene does. Also, [[spoiler:the 51st battle in the fighting ring is Double God Hand Gene.]]
* ''Franchise/MetalGear'':
** While has lots of EvilCounterpart characters, but few of them fall under this. One that does is The Boss from ''VideoGame/MetalGearSolid3SnakeEater''. In that game, you basically have 3 specialties: guns, CQC, and camouflage. The Boss carries the Patriot machine gun, is the one who ''taught'' you CQC, and wears a white jumpsuit which provides excellent camouflage in the field of flowers where you fight.
** [[spoiler:Liquid Ocelot]] from ''VideoGame/MetalGearSolid4'' engages the player in a close combat based fight at the end.
** Gray Fox from ''VideoGame/MetalGear2SolidSnake'' is limited to exactly what Snake can do - running around and punching.
** A very interesting example in ''VideoGame/MetalGearAcid2'' - [[spoiler: Venus]] [[HeKnowsAboutTimedHits breaks the fourth wall]] to announce that she's going to use Snake's deck, even drawing the cards in the exact same order that he does. Since there's a lot of flexibility with the card-based battle system, though, it's very unlikely that she'll act anything like Snake at all once in combat - for instance, a good way of fooling her is by setting up a deck with a few strong equippable gun cards and lots of weaker guns to use as ammunition, which will often cause her to equip the weak ones and load them with the strong ones. The version of her that appears in the BossRush also uses whatever deck Snake has.
* Wario from ''VideoGame/SuperMarioLand2SixGoldenCoins'' is basically a giant evil Mario. He starts out trying to jump on Mario's head, then uses a black carrot to copy Mario's rabbit form, then finally copies Mario's fireball power with a black fire flower.
* Ness's Nightmare from ''VideoGame/EarthBound'' possesses all the skills that Ness has. To make it even more apparent, this is also a DuelBoss.
** In ''VideoGame/{{MOTHER 3}}'', the Masked Man fights in a similar style to Lucas and his party. He hits hard with his weapon, has the ability to destroy your shields like you can with the Shield Snatcher, uses a lightning attack that is similar to PK Thunder, and also possesses PK Love Alpha, Beta, Gamma, and Omega, which is the same powerful technique Lucas uses. [[spoiler:The reason the Masked Man can use the powerful PK Love attack is due to him being Claus, brother of Lucas.]]
* 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.
* In the final stage of ''VideoGame/{{Gungrave}}'', Grave's first battle in the level is a boss encounter with his former apprentice, Bunji Kugashira. While he doesn't look like his mentor or have a coffin-like weapon, he too dual-wields a pair of pistols and regenerates his health the way Grave regenerates his shield. Bunji's also capable of using his own unique Graveyard Special, which is the same boss fatality move that Grave uses, except Bunji can use his any time he's close to you. His battle even ''starts'' with him sliding at Grave, trying to catch him and initiate the move.
* Allen O'Neil from the ''VideoGame/MetalSlug'' series. Nearly every other boss is some sort of exotic military vehicle, but Allen is just a man with a gun, grenades, a knife, and a whole lot of muscles.
* ''GargoylesQuest II'' had a literal Mirror Boss, a magic mirror who could transform into a copy of your character. There was [[PuzzleBoss a trick]] to beating it: [[spoiler:any damage you inflict while it's copying you is reflected back on you, so you can only attack it while it's in its natural mirror form]].
* [[AntiVillain Asch]] of ''VideoGame/TalesOfTheAbyss'' is this to Luke, with very good reason -- [[spoiler:[[CloningBlues Luke is his clone]]]]. Indeed, in Luke's clashes with him (which are, of course, DuelBoss Fights), he has most of the same skills that Luke does -- the only major difference in ability is the fact that Asch can cast spells and his [[LimitBreak Mystic Arte]] is different, though functionally similar.
** Most of the other Six God Generals count as well, though to what extent varies from general to general.
** The cameo battle plays this brilliantly. [[VideoGame/TalesOfEternia Reid]] to Luke/Guy. [[VideoGame/TalesOfPhantasia Mint]] to Tear/Natalia. [[VideoGame/TalesOfDestiny Philia]] to Jade. [[VideoGame/TalesOfDestiny Nanaly]] to Anise/Natalia. All at once. There's a reason why it's considered by some to be the [[Awesome/BossesTalesSeries best boss battle in the series]].
* In the second half of ''VideoGame/TalesOfLegendia'', the majority of the non-monster bosses are shadow versions of your party members who can use all of their respective artes, but have the added benefits of flinch resistance, and in the case of the magic users, quick or instant casting on their spells.
* The bonus boss of ''VideoGame/TalesOfXillia'' copies the fighting styles of your party members, first imitating Alvin, then duplicating himself and imitating Leia and Rowen, then duplicating himself once more to imitate Jude, Milla, and Elise.
* Played completely straight in ''VideoGame/TalesOfXillia2'' with [[spoiler: Victor]], who's an AlternateSelf of [[spoiler: Ludger]] and has access to every trick in his arsenal (Including ones you might not have learned yet). You also fight shadow versions of your party members in the bonus dungeon, who despite facing you solo are extremely threatening due to their drastically increased stats.
* Near the end of the first ''VideoGame/TombRaider'', Lara meets a copy of herself which does exactly what she does. Shooting it only results in Lara getting injured. You have to lure it into a deathtrap to proceed.
* Toward the end of ''VideoGame/{{Maximo}} vs. The Army of Zin'', you have to fight Zin who are explicitly modeled after Maximo, some of which even wield a Hammer of Heroes knockoff. [[EvilKnockoff They hardly count as bosses, though.]]
* In the Flash game ''VideoGame/GinormoSword'', the Temple of the Moon contains a BonusBoss called {{Doppelganger}} who looks identical to you and has a sword [[{{BFS}} exactly as big as yours]]. And, as the game's name implies, that's pretty freaking big. [[spoiler:Unless, of course, you have your sword reforged to its minimum size before fighting him...]]
* In the SegaGenesis version of ''VideoGame/{{ESWAT}}'', the final boss is a man in a red version of your PoweredArmor, with several upgrades such as the ability to fire charged shots without charging.
* Green in ''VideoGame/GunstarHeroes'', a former ally of Red and Blue brainwashed to serve the Empire, is a Mirror Boss in the final chapter. His BossSubtitles list his attacks as "The Gunstars' Actions", which is appropriate, since he can jump, slide, and throw just like you can. But instead of using a gun, he uses throwing stars. This is not true of the remake/sequel, ''Gunstar Super Heroes'', where Green just reuses the [[TransformingMecha Seven Force]] he used earlier.
* Zohar from ''VideoGame/SilhouetteMirage''. Like Shyna, Zohar can switch between the Silhouette and Mirage attributes -- and while Shyna's attribute depends on which way she faces, Zohar can change at will. Plus, Zohar's move arsenal contains several attacks which are counterparts to Shyna's -- namely, the homing shot and sword attack.
* Penta from ''VideoGame/RadiantSilvergun'' is a copy of your AirborneAircraftCarrier base, Tetra. It attacks with two copies of the Silvergun which use all the same weapons that you can use. I hope you've memorized yourself.
* Tageri from ''VideoGame/{{Ikaruga}}'', a boss who is capable of instantly switching between the white and black attributes just like your ship can, and intermittently using your homing laser superweapon, which you can only survive by absorbing it with the matching attribute. Of course, you're still a small fighter plane, and it's a giant sphere shooting waves of [[BulletHell danmaku]] at you, but it sort of works.
* Brad from ''VideoGame/SinAndPunishment'', who wields a gun/sword weapon exactly like yours. He's first fought in a shootout where you have to dodge his aiming cursor to keep him from shooting you; once that's done, he closes in for a sword duel.
* Samantha from ''VideoGame/StretchPanic'' is set up to be an EvilCounterpart to Linda even in her [[AllThereInTheManual backstory]]: they were born less than a year apart, and Samantha's transformation revolves around an object which is important to her, a toy fish she was given by her mother. This toy fish is connected to her by a prehensile chain and acts like an extra limb, being used to grab and throw objects much like Linda's scarf hand.
* An interesting example in ''HeroesOfMightAndMagic 5''. Visiting a sphinx will trigger a riddle with three choices. A wrong answer will result in a battle against a copy of the triggering hero, with the same level, skills, abilities, artifacts, and troops. [[TheComputerIsACheatingBastard And they usually have the initiative.]]
* The final battle of ''UltimaIV: Quest of the Avatar'' is against clones of all 8 recruitable party members. Note that there is one party member of each class, and you can recruit all of them except the one who shares your class, so the clones usually end up having the exact same party makup as you.
* A similar situation occurs in the final battle of ''RingsOfPower'', whereas your evil rival has gathered a party of adventurers with the exact same class composition as your own to fight you.
* The ''VideoGame/{{Bomberman}}'' games have a trend of including a QuirkyMinibossSquad of evil bombers as bosses. This trend started with ''Super Bomberman 2'' and its Five Bad Bombers, who had both unique bombs and HumongousMecha -- including, notably, Brain Bomber's giant Bomberman mecha which could also lay bombs.
* ''VideoGame/{{Pulseman}}'' featured as the boss of Stage 5 a dark Pulseman who attacked using a similar 'Voltecker' dash as Pulseman's own (e.g. [[http://www.youtube.com/watch?v=grSnRAZieeE#t=05m40s this video]]).
* Bass, introduced in ''VideoGame/MegaMan7''. An evil robot created by Dr. Wily to be Mega Man's equivalent in every way, he even has a robot dog, Treble, that he can combine with much like Mega Man can combine with Rush.
** Much earlier than him is Proto Man in ''VideoGame/MegaMan3'', under his guise of Break Man.
** In ''Operate: Shooting Star'', [[VideoGame/MegaManBattleNetwork Rockman.EXE]] and [[VideoGame/MegaManStarForce Ryuusei no Rockman]] end up fighting due to a misunderstanding. Ryuusei uses a similar fighting style to EXE with a few negligible differences.
** The dark versions of the navis in ''{{Mega Man Battle Network}}'' 4 and 5 all use the battle chips and program advances that you've been using the most frequently in addition to their own attacks. This can end up making them very difficult if you favor the use of unavoidable attacks, and was particularly nasty in 4, where they put you up against one of them early enough in the story that they could OneHitKill you with a program advance if you had used one prior to the fight.
** Preceded in the original ''VideoGame/MegaMan1'' by the second fortress boss, a Mega Man clone who had all of the original's weapons.
** ''VideoGame/MegaManZero 3'' has its own mirror boss, Omega, [[spoiler:with a twist being that TheHero is in a cloned body, while the FinalBoss is the original body.]]
** The Mega Man clone makes a reappearance in ''VideoGame/Rockman4MinusInfinity''. This time he is monochrome. After beating him once, he steals 4 of Mega Man's weapons with Dr. Wily's Stealing System and gains some color. Fortunately, he does not know how to use the weapons well.
* Kojiro in ''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.
** President Gandrake from ''Musashi: Samurai Legend'' actually transforms into a copy of Musashi [[spoiler:after stealing the five elemental swords]] for his boss fight.
* Sabata from ''VideoGame/{{Boktai}}''. While Django wields the Gun Del Sol, a weapon which stores and fires beams of sunlight, Sabata uses the Gun Del Hell, which uses the power of darkness to achieve the same effect.
* Anubis in ''VideoGame/ZoneOfTheEnders: The 2nd Runner''. It was built as part of the same project as Jehuty, and not only are they the only two Orbital Frames in existence that can use Zero Shift [[spoiler:and control Aumaan]], but their normal beam attacks are parallel as well.
** In the original ''Zone of the Enders'', Viola and her frame Neith are a Mirror Boss, mainly because all the other bosses are absolutely humongous even by HumongousMecha standards.
* In ''VideoGame/SagaFrontier'', the entire purpose of Blue's quest is to prepare for a WizardDuel with his brother Rouge. When the duel finally happens, you find out that Rouge has mastered [[MutuallyExclusiveMagic the opposite]] of every school of magic that Blue learned (except for Realm magic, which they both start with).
** Red's quest has a RecurringBoss named Metal Black, a robot warrior who remodels himself after every defeat. His final form is modeled after Red's superhero identity, Alkaiser; he even has a copy of Red's finishing move, Dark Phoenix.
* [[spoiler:The Guy]] from ''VideoGame/IWannaBeTheGuy'' looks mainly like a larger version of The Kid, right down to the blue jumpsuit and red cape. And the gun.
** [[spoiler:[[JustifiedTrope It helps that he's the kid's father]].]]
* One mission in ''[[VideoGame/NarutoClashOfNinja Naruto Shippuden: Clash of Ninja Revolution 3]]'''s story mode has Guy fighting himself. The CPU-controlled character copies the exact same moves you do. However, its chakra gauge fills up slightly slower than yours. So not only can you pull off your own special sooner than the computer, but you can even have the computer waste its own.
* The Handsome Men from ''VideoGame/{{Killer7}}'' are a team of rival assassins who battle the Smith Syndicate in a DuelBoss sequence. Not only do they have one member for each of your 8 characters, but they all copy the weapons those characters use... and every single motion and shot you make, turning every battle into a war of attrition which you are destined to either [[ForegoneVictory win]] or [[HopelessBossFight lose]]. [[spoiler:If you pay attention to this being a Mirror Boss along with the cutscene afterwards, this is ultimately Foreshadowing to Harman's status as a Decoy Protagonist to Garcian, as Handsome Red is to Handsome Pink.]]
* In ''VideoGame/{{Oni}}'', after Konoko learns her true identity, she has a trippy dream sequence that culminates in her fighting a hostile dream version of herself. The dream Konoko is faster than most enemies and has the same move set as the player, but doesn't use the most powerful specials, so she's not as tough to beat as she could be.
* ''AlienHominid'' has the final boss, a beefed-up, macho version of the titular character. He uses larger-scaled versions of all of Alien Hominid's attacks. Oh, and he can [[MadeOfIron take more than fifty times the damage]] that [[OneHitPointWonder Alien Hominid]] can take...
* ''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.
* Interestingly subverted in ''Baldur's Gate: Tales of the Sword Coast'', 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.]]
** Played with in ''BaldursGate II'', where your initial boss fight with [[spoiler:Irenicus]] has him cast a "Summon Clones" spell which doubles your party members as hostiles, only without equipment or spells (so -- harmless, really).
** Also subverted near the end of ''Baldur's Gate II'', where a random encounter has initially friendly [=NPCs=] turning into doubles of your party and attacking if you say the wrong thing -- but gives them none of your party's powers, instead making them into a moderately challenging fight at best.
* In ''VideoGame/MarioAndLuigiBowsersInsideStory'', the Mario Brothers infiltrate Bowser's brain, where his memories can become tangible. His memories of Mario and Luigi attack the real ones using moves from older ''Franchise/{{Super Mario|Bros}}'' games, including other ones from the ''VideoGame/MarioAndLuigi'' series. Bowser gets to fight his own mirror boss at the end of the game, and since Bowser is already a VillainProtagonist, it's EvilVersusEvil.
* Kojack, the Access Hangar boss in ''VideoGame/MadWorld'', looks a lot like Jack and fights identically to him on a motorcycle. The commentators, of course, have a field day with this -- "Jack must feel like he's kicking his own ass!" [[BreatherBoss He's hardly a threat, though.]]
** Less notable but still present is [[spoiler: the final boss: The Black Baron]], who's on much more equal terms with Jack than most of the other bosses, edging on FearfulSymmetry in their power struggle. [[spoiler: They'd be even more similar if Jack's moveset was more like how it is in ''VideoGame/AnarchyReigns'', such as the spinning kick dive and [[LimitBreak Rampage Mode]]]].
* ''Franchise/KingdomHearts'':
** ''VideoGame/KingdomHearts358DaysOver2'' has [[spoiler:Xion]], who not only fights a lot like Sora from the first game, but also has several of his special attacks, including Sonic Blade, Ragnarok, and Ars Arcanum. [[spoiler:Which makes sense, considering what [[strike:she]] it [[OppositeSexClone is.]]]] Not to mention that in its Final Form, it will use Sora's [[LimitBreak Trinity Limit]] on you.
** Terra's final boss in ''VideoGame/KingdomHeartsBirthBySleep'' exclusively uses Terra's own moves against him. His best moves, like Quake and Meteor, Chaos Blade, and the like, and his two best Shotlocks: Dark Salvo and [[{{BFG}} Ultima Cannon]]. He can even go into Command Styles that Terra is able to use -- specifically, Dark Impulse. He can even do things that normally only the player characters can do, like dash, block, counterattack, and ''[heal himself with Cure spells'' (he even chuckles when he whips that one out). This is all handily explained by the fact that [[spoiler:Terra's final boss is ''Terra himself''. Specifically, it's Master Xehanort after having [[GrandTheftMe taken over Terra's body]]. You play as Terra's cast-off armor, which has [[AnimatedArmor risen up to fight]] under the influence of Terra's memories.]]
** In ''VideoGame/KingdomHearts3DDreamDropDistance'', the [[spoiler:Armored Ventus Nightmare]] fights just like its playable namesake from the aforementioned game, right down to finishing the match with a Shotlock, albeit mixing darkness into many of its attacks and having a few new ones of its own. It even uses [[ThrowingYourSwordAlwaysWorks Payback Raid]] as a counterattack whenever you knock it back and is the only boss to have such an ability.
* Implemented with in-universe [[JustifiedTrope justification]] in ''DotHackGU'': The Doppelgangers are designed to be a copy of the player that appears if they hang around too long in a field-type area. The thing is that they are always 8 levels higher than you are (but not above the level cap of the game; 50 in the first game, 100 in the second, and 150 in the third), always has +50% speed, constant HP/MP regen, damage reduction, healing spell, has weapon effects that mirror yours if your weapon is fully customized, and can change weapons at will (mirroring what ''you'' use). The difficulty spike reaches to NintendoHard levels for unprepared players in Volume 3, although the rewards (provided the player played the two volumes before it) are phenomenal.
* When you finally fight [[PresidentEvil Richard Hawk]] in the Las Vegas level in MetalWolfChaos, he has a special ops suit just like you, complete with its own LimitBreak.
* In the ''VideoGame/{{Metroid}}'' franchise, you face off against evil Samus duplicates several times. However, the only one of them that fully represents a Mirror Boss is SA-X. Dark Samus may look like Samus and use the Morph Ball, but she moves very quickly and ''flies''. Even Gandrayda-Samus takes liberties with Samus's abilities. SA-X is confined to things that Samus, post-Super Metroid, could actually do, with the sole exception being the ability to perform the Screw Attack with a completely horizontal trajectory.
* ''VideoGame/TheElderScrollsIVOblivion'' expansion ''Shivering Isles'' has you fight a dark shadow of yourself at one point. As Oblivion uses a character creation system with stats for specific abilites, this shadow [[spoiler:is literally your own character, copied and coloured pitch black, with your exact stats and level, right down to the equipment it carries.]] Its status as a [[ThatOneBoss That One Boss]] depends on how much your own character kicks ass, as the computer has all your weapons and abilities without the need to [[TheComputerIsACheatingBastard press buttons to switch between them.]]
** One strategy for easily defeating him is to [[spoiler:change your default weapons and armor to something very weak, then when you finally get in the fight with him, change back to your better armor and sword and slaughter him before he can do the same.]]
* ''VideoGame/QuestForGloryIII'' has a literal (and particularly unpleasant) Mirror Boss fight near the end of the game. The hero and four of his friends arrive in a room with five mirrors, each character walks up to a mirror, and then the reflections mutate into demonic versions of themselves and attack. Hitting your own reflection causes you to take damage, on top of the damage he's already doing to you. There's no way to win on your own... you just have to try not to die until another buddy shows up and stabs your reflection in the back.
* In ''VideoGame/TheWorldEndsWithYou'', certain varieties of Fox Noise can pull this trick on you. When they have enough tails, they can transform into masked copies of Neku and attack with versions of your own Psychs. One of them is an optional boss, the other is a non-boss enemy.
** [[spoiler:Kariya and Uzuki]] are a better example. The pair has a light puck, are a pair (sharing the game's two screen combat), and attack with a few common Psychs.
* The unreleased ShootEmUp ''ChimeraBeast'' has the FinalBoss, essentially an oversized and more evolved version of the player's [[HordeOfAlienLocusts eater]].
* [[spoiler:The final boss]] in ''RatchetAndClankFutureACrackInTime'' is another [[spoiler:Lombax]], complete with the agility and absurd arsenal that Ratchet has.
* [[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.]]
* ''VideoGame/WorldOfWarcraft'' has 2 bosses where one must face clones of your current party. One is relatively hard, as the clones have ablities and attack patterns based on the clonee's class and spec (IE cones of healers will heal) and each player must fight them off alone. Should you defeat them all, you'll join another party member who is still fighting them until all 5 groups are cleared and the actual boss fight continues. Notably, your own clone set will not have a clone of you, though everyone else will have one of you. In the other fight, they are relatively weak and just act as support for a simple boss.
** There is also one quest where you fight against your inner turmoil which is a basically a clone of yourself, though the character only uses melee attacks despite the fact you may be a magic user character, and lacks any of your abilities and strength, making it a easy fight.
** Not quite a mirror match, but much more formidable than the above examples, is the Faction Champions encounter in the Trial of the Crusader raid, which pits you against a group of bosses that mimic the abilities of player characters (in a simulation of a PvP Arena match). While they lack the benefit of human intellect and are fewer in number than your raid group, they are statistically far superior to a PC of the same class and spec and have a habit of dogpiling one member of your team.
** There's also [[http://www.wowpedia.org/Nefarian_(tactics) Nefarian]] ([[RecurringBoss the old one]]), who while not exactly mirroring your abilities, does mirror some icconic class abilities: Druids are forced into cat form, Rogues are teleported in front of him and stunned there, he Death Grips people if there's a Death Knight around, etc.
** And [[http://www.wowhead.com/npc=24239 Hex Lord Malacrass]], a Zul'Aman boss that steals some of your (most annoying) abilities.
* On and above the hard mode of ''VideoGame/NinjaGaiden Black'', certain battles are replaced with a 'Fiend Ryu'. This being VideoGame/NinjaGaiden, Fiend Ryu is you, only [[TheComputerisaCheatingBastard a lot better than you.]]
* Issue 17 of ''VideoGame/CityOfHeroes'' introduced Doppelgangers, enemies who copy the player's look and powers. However, they are not exact duplicates -- most notably, they only copy the powerset, but not the particular powers a player has picked. Every story arc introduced in Issue 17 contains, in some way, one of those. One mission gives you the option to fight ''eight copies of yourself at once''. The badge for achieving that feat is particularly amusing.
--> '''''Army of Me:''' You don't understand the math behind it, but you're pretty sure you're equal to or greater than eight of yourself.''
* [[spoiler:The Elites]] in ''HeroCore''. Significant in that it isn't just a random EvilKnockoff; [[spoiler:they foreshadow that Flip Hero is also an Elite that once served in Tetron's army]].
* The "Shadow Boss" at the end of the NES version of ''VideoGame/DoubleDragon'' is none other than Billy's twin brother Jimmy, who has all the same moves as the player and more health. This is actually a carryover from the arcade version, in which both players were forced to fight each other at the end (Jimmy was originally Player 2 in the arcade version, but became the FinalBoss in the NES version due to the omission of the 2-Player mode).
** Jeff, the Mission 2 boss in the arcade version, also fits this trope, being a Lee brother HeadSwap with all the same moves.
** In the arcade version of ''Double Dragon II: The Revenge'', the final boss is a Lee brother clone who has all the same moves, plus an energy beam attack and the ability to possess the player's body and drain his health. If both Lee brothers are present, then there will be a second clone as well. The clones appear in the NES version as well, where they are the last enemies before the new final boss.
* In ''VideoGame/InFamous'', final boss Kessler is one of these. Almost all of his powers look like stronger versions of yours. And there's a very good reason for this: [[spoiler:He's a SadistTeacher version of Cole from a BadFuture who is here to SetRightWhatOnceWentWrong]].
* In ''VideoGame/{{Ys}}: The Oath in Felghana'', a game full of battles with monsters, Chester is the only other [[TheCorruption complete]] human and the only non-{{Mook}} swordsman you will fight... and [[ThatOneBoss he knows what he's doing.]]
* The final stage of ''VideoGame/{{Depict1}}'' pits you against your EnemyWithout. [[BlatantLies He copies all your moves flawlessly and can't be killed unless you throw yourself into the deadly gems, killing him as well.]] [[spoiler:Actually, no. There's ''one'' thing you can do that he can't. If you managed to clear the cliff using only one spike, you can jump over the gems and fire the other one to freeze yourself in midair for a moment, allowing you to land safely while he falls to his doom. DECEPTION->POETICEND.]]
* In a rare movie example, ''Film/ScottPilgrimVsTheWorld'', the last enemy Scott Pilgrim has to face is Nega-Scott, a shadowy version of himself... but instead they talk things out and decide they have a lot of things in common, and head their separate ways.
** In the comic, Nega-Scott is "defeated" when Scott accepts him and admits that he's partly to blame for things going wrong with his life, since fighting him just means he's fighting himself and refusing to learn anything.
** The [[VideoGame/ScottPilgrim 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.
* In ''VideoGame/{{Purple}}'', all but one of the mini-bosses you encounter on the map wield the exact same weapons you do. [[spoiler:The final boss also uses these weapons, but they're bigger and some have extra effects.]]
* ''VideoGame/SuperPaperMario'' has the boss of World 4, Mr. L. He jumps and moves around like the player, and he can even use items to heal himself.
** [[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.]]
* Shadow Mario from ''VideoGame/SuperMarioSunshine'' uses many of Mario's jumping abilities to escape him whenever he shows up to kidnap Princess Peach. His Magic Paintbrush matches F.L.U.D.D. insofar as that they were both made by Professor E. Gadd. [[spoiler: He's actually Bowser Jr.]]
* Cosmic Mario from ''VideoGame/SuperMarioGalaxy'' uses the same moves as Mario, but to race him rather than fight him. In ''VideoGame/SuperMarioGalaxy2'' and ''VideoGame/SuperMario3DLand'' meanwhile, Cosmic Clones take it a step further by spawning a few steps behind him and mimicking Mario's movements to the letter so that if he stops for too long they'll inflict CollisionDamage.
* The final boss of ''VideoGame/SuperMario3DWorld'' uses the [[MesACrowd Double Cherry]] and Super Bell during the fight.
* The second-to-last boss in ''BioMetal'' uses all three MutuallyExclusivePowerups that the player could use, except upgraded.
* ''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.
** It was also used in ''VideoGame/KnightsOfTheOldRepublic'' in the final boss fight.
* 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.
* Happens near the end of ''VideoGame/{{Drakensang}} 2''. The clones sports the same weapon you're using, so if you disarm your character right before the cutscene where the clones are created, the clones are unarmed and helpless.
* Mr. X from ''VideoGame/KungFuMaster'', who can attack with the same punch and kick animations as Thomas, in addition to his advantage of [[TheComputerIsACheatingBastard knowing how to block]]. This is more noticeable in the NES port, where Mr. X is a head-swapped black PaletteSwap of Thomas.
* The third boss in ''CrashBandicoot2NTranced'' is Fake Crash, who mimics the player's movements. Like the ''Franchise/TombRaider'' example, the only way to beat him is to move him so he stands where you shouldn't. If you collide into him, you'll die and he'll produce a cheering animation.
* Mecha-Turtle in ''VideoGame/TeenageMutantNinjaTurtles''(NES).
* [[TheRival Jin]] from ''VideoGame/PanzerBandit'' uses an exact duplicate of [[TheHero Kou]]'s moveset, with the exception of the visuals of his second Hyper attack (though move-wise it's the same effect). [[TheVoiceless Tsubai]] serves as a mirror to [[GunsAkimbo Ein]] as well, mostly in techniques having the same function rather than being mirror-sprited like Jin's.
* ''VideoGame/{{Tenchu}} 3: Wrath Of Heaven'' introduces Hyakubake, a MasterOfDisguise who takes on either Rikimaru or Ayame's form in the opposite's Story Mode, making use of their techniques and even a few of the player's items (like the Blowgun). This trend of pitting one of the two (or three) playable characters against the other is used in other games (''Fatal Shadows'' and ''Time of the Assassins'', for example), though in most of those cases it's the actual character instead of a disguised enemy.
* ''VideoGame/CannonDancer'' brings forth [[EvilKnockoff Fake]], a dark-skinned clone of main character Kirin who can do everything he can except create [[DoppelgangerAttack energy clones of itself]].
* Letho in TheWitcher 2. As a Witcher himself, he can use Signs as well as use traps and bombs like Geralt does.
* Nemesis in ''VideoGame/DarkSector'' uses many of the same abilities that you do, including charging a glaive with elemental energy. Completely {{Justified|Trope}} by the fact the player received a copy of Nemesis' powers.
* DungeonSiege III contains several fights with Archons, who have the same powers as Anjali, though [[TheComputerIsACheatingBastard they get to use the full set in both forms]] instead of needing to alternate to use them.
* The Black Phantoms in ''VideoGame/DarkSouls'' are basically AI-controlled [[PvP Invaders]].
** To a lesser extent, [[spoiler:Lord Gwyn, the final boss.]] He operates very differently than the player character, but he is a swordsman of roughly the same size as the PC, whereas most of the game's bosses are [[AttackOfTheFiftyFootWhatever giant monstrosities.]]
* In ''DeathSmiles'', Sakura is the boss of the Swamp, which means that if you're playing ''as'' her in Mega Black Label mode, you fight a mirror image of her.
* ''VideoGame/{{Bayonetta}}'''s rival, Jeanne. She'll gain abilities as Bayonetta does during the story, getting harder and harder but never outright overpowering Bayonetta and her abilities.
** [[MarathonLevel Angel Slayer]], however, 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/TheWonderful101'':
** Prince Vorkken uses the Unify Morph, which functions much the same as the Wonderful Ones' Unite Morph. Vorkken, however, uses a bit of MyRulesAreNotYourRules (such as being capable of blocking ''any'' attack with Unify Guts) to increase the challenge. Like Jeanne in ''Bayonetta'', he will also gain abilities as the game goes on, and will never use an ability that the player has no access to yet (excluding Vorkken's Boomerang and Chewgi's Naginata, their own signature morphs that they will always have access to). In the case of their [[SecretAIMoves special Unite Morphs]] where they transform into GEATHJERK enemies, they won't transform into something the group hasn't encountered yet.
** [[spoiler:Wonder-Jergingha]] will use the pieces of the shattered platforms and machinery around him to mirror the Unite Morphs of the team. He will only use the main seven[[note]]Hand, Sword, Gun, Whip, Hammer, Claw, and Bomb[[/note]], though.
* The climactic battle of Level 4 in ''VideoGame/{{Descent}} 3'' is a duel with one of Dravis' Black Pyros.
* The final boss fight of ''VideoGame/AsurasWrath'' is Gohma Vlitra's Core, which looks like a bigger and meaner, but still nearly identical version of Berserker Asura, Giant Arms and all.
** The final boss of the DLC [[spoiler:uses quick time events, even with similar on-screen inputs]].
* In ''VideoGame/{{Super Robot Wars Z}}2'', [[http://www.youtube.com/watch?v=I-A96vSQKvA Anti-Spiral pilots]] a PaletteSwap of the Gurren Lagann with Anti-Spiral Nia instead of the Grand Zamboa because Tengen Toppa wasn't in the game. He also pilots Chouginga Anti-Gurren Lagann.
* In ''Videogame/GuildWars'' ''Prophecies'', the final test for Ascension is defeating an enemy with the exact skills your character has equipped.
* The Traitor's Keep DLC in ''VideoGame/FableIII'' [[spoiler:ends with a fight against a doppelganger of your Hero. The copy utilizes all your abilities while [[TheReasonYouSuckSpeech talking you down and telling you why you need to die.]]]][[note]]Though if you've succeeded in playing as a good Hero up to that point, said speech (which essentially remains unchanged) starts to sound more like the copy's grasping at straws trying to find legitimate reasons to kill you.[[/note]]
* Inverted with the fight with Arikan in ''VideoGame/CopyKitty''. The player is mirroring ''him''. Even better, when Arikan decides to get serious and TurnsRed, the player ''copies that too'', and gets the same power enhancement.
* In ''VideoGame/{{La-Mulana}}'', the MiniBoss Shu (or Chi You in the remake) somehow can use all the player's sub-weapons.
* The first ''Franchise/StarTrek: StarfleetCommand'' game has your squaring off against your MirrorUniverse counterpart with the exact same ship.
* A slight variation in ''StarTrekThe25thAnniversary'', where 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.
* In ''VideoGame/GravityRush'', Raven serves as this. She even counters Kat's finishing move by mimicking it.
* In the ''Citadel'' DLC pack of ''VideoGame/MassEffect3'', the primary antagonist is [[spoiler:[[EvilTwin an evil clone of]]]] [[TheHero 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 4 Faeries in ''NeoQuest II''. The Earth Faerie mirrors Rohane (has Critical Hits and Stunning Strikes), the Fire Faerie mirrors Mipsy (Direct Damage, Group Direct Damage), the Dark Faerie mirrors Talinia (sort of; it's the one that inflicts status effects, even if Velm gets some of them on your team) and the Water Faerie mirrors Velm (Healing, Group Healing).
* ''VideoGame/{{Dishonored}}'' has Daud, who like Corvo has powers granted by The Outsider and uses SwordAndGun in combat. Of course, the player doesn't have to directly fight him and can simply sneak up on him or sneak by him if they wish.
* The game based on ''XMenOriginsWolverine'' had you going up against another Wolverine in order to unlock new costumes.
* ''VideoGame/{{Kamui}}'' has the bosses of Stage 4, a squad of Kamui fighters just like your ship. Just like the ship you pilot, they can use standard shots, lock-on shots, and a beam attack (although heavily modified).
* Strider Hien in ''VideoGame/{{Strider}} 2'' has all of Hiryu's techniques and movement, jumping and climbing included. The only difference is that he fights with ranged attacks instead of Hiryu's close-and-personal approach.
* Among all the giant bio-organic monsters in ''VideoGame/RunSaber'' there's Kurt, a defective Run Saber who fights with similar attacks to the protagonists, and even has his own Special Attack.
* Raksasha, the cyborg samurai from ''VideoGame/{{Hagane}}'', is the only boss without a OneWingedAngel true form to fight Hagane on even grounds as a normal-sized warrior.
* Arthur from ''VideoGame/GhostsNGoblins'' fame was finally graced with a similarly-sized BlackKnight boss battle in the iOS ''Gold Knights'' duology.
* Moon Snail, the final boss of ''VideoGame/{{Snailiad}}''. Aside from changing his own gravity, he uses Devastator-style boomerangs and dark-colored waves in his first form. [[spoiler:As [[OneWingedAngel Giga-Snail]], he uses bigger Rainbow Waves, as well as using the Devastator-peashooter bullets. He even uses the ''{{idle animation}}'' as an attack; the [[CatchingSomeZs Z's]] fly off in your general direction.]]
* The final boss of ''VideoGame/PacManWorld'' uses one of Pac-Man's moves for each of its phases.
* ''VideoGame/FinalFantasyXIV'' has a few bosses that are essentially the classes players use (Thamatuge, Archer, Lancer, etc) and can use the same skills as the player can. However, some of the boss characters will use skills that are unique to them and can't be used by the players.
