History Main / UpgradedBoss

** In the UsefulNotes/GameBoyAdvance remake of ''VideoGame/DonkeyKongCountry1'', most of the bosses have different attack patterns than their UsefulNotes/{{SNES}} counterparts:

** The remake of ''Videogame/SuperMarioRPG'' allows the players to challenge defeated bosses to a rematch.

* ''VideoGame/{{Terraria}}'': The Mechanical Bosses are essentially stronger versions of The Eye of Cthulhu, the Eater of Worlds, and Skeletron with new abilities. Additionally, the Queen Slime in Hardmode is one for the [[WarmUpBoss King Slime]].

* ''VideoGame/HollowKnight'': Some bosses leave behind a corpse, which can be dreamnailed to fight a much harder version of the boss. These dream rematches are entirely optional and reward the player with Essence, which is part of the progression towards the true ending.

* ''VideoGame/DevilMayCry3DantesAwakening'': Vergil is fought 3 times in a single playthrough: once at the seventh mission, once near the middle, and once as the FinalBoss. At first, he only fights with his katana, Yamato, and uses simple tactics. The second time you fight him, he has acquired the Beowulf gauntlets/greaves and fights you with it, though he sometimes shifts to Yamato again mid-fight; he also can use [[SuperMode Devil Trigger]]. In the final battle, he lost the Beowulf, but gained the [[{{BFS}} Force Edge]] and uses several attacks similar to yours (Dante's) alongside his new attacks with Yamato, and he also will use Devil Trigger mid-battle. In the harder difficulty modes, he'll also use [[OrbitingParticleShield Spiral Swords]] to make the fight trickier.

** ''VideoGame/SuperMarioOdyssey'': You can fight all of the bosses again in the [[spoiler: Mushroom Kingdom by jumping into paintings]]. In addition, you can fight the Broodals one more time on the [[spoiler: Dark Side of the moon]] in a BossRush. In all cases, the bosses have harder to dodge attacks or even change some mechanics of the fight completely. A harder version of Bowser can also be fought as a reward for [[OneHundredPercentCompletion collecting all of the Power Moons.]]

* ''VideoGame/MetroidOtherM'': The second battle against [[MechanicalAbomination Nightmare]] has him use two new attacks, a BreathWeapon and firing a black hole that attracts all projectile weapons to it for a short period of time. Though he's not that much tougher since Samus obtains the Gravity Suit just before fighting him again.

* In ''VideoGame/PokemonBrilliantDiamondAndShiningPearl'', after becoming Champion and getting the National Dex, you can rematch Barry, the Gym Leaders, the Elite Four, and Cynthia in a greatly upgraded fashion. The Gym Leaders and Rivals all have a full team of 6 Pokémon with optimal [=IVs=] and maxed out [=EVs=], useful egg moves, beneficial Hidden Abilities, and items normally seen in competitive such as the Choice items, Life Orbs, and Focus Sashes.

* ''VideoGame/AVeryLongRopeToTheTopOfTheSky'': Phobos, who is fought twice, all as {{Bonus Boss}}es, with the second time turning the fight into a WolfpackBoss battle by summoning two clones [[TurnsRed when at half health]].

-->-- '''C.Q. Cumber''', ''VideoGame/Splatoon2: Octo Expansion''

* ''DragonQuestXI'' has you fight darker versions of the Spectral Sentinels in [[BonusDungeon Drustan's Labyrinth]], some which will fight you in [[DualBoss pairs]]. All of them have to beaten in a certain amount of turns to complete the fights and all of them have a remix of VideoGame/DragonQuestIII's boss theme to set the tone for each fight.

* ''Franchise/MegaMan'':
** ''VideoGame/MegaManClassic''
*** Guts Man is one of the most memorable bosses in the first ''VideoGame/MegaMan1'' game, but only because Wily keeps using his design as a template. Guts Tank, one of the fortress bosses in ''VideoGame/MegaMan2'' is, as its name implies, a giant tank modeled after Guts Man, while in ''VideoGame/MegaMan7'' Wily steals a Guts Man replica from a museum, which he then remodels into another fortress boss, Guts Man G, this time replacing one of his hands with a giant clamp and giving him treads.
*** Also from ''7'' is Bass. He is fought twice as a non-remarkable MiniBoss, first in the introductory level then in the first fortress level. In the second fortress level, however, he now turns into "Super Bass", where he combines with his robot wolf Treble in a form directly mirroring Mega Man's own Super Adapter upgrade. In ''VideoGame/MegaMan8'', Bass then powers himself up with Evil Energy (the Macguffin of the game) and this version of Super Bass comes with new attacks.
** ''VideoGame/MegaManX''
*** After defeating a few Maverick bosses in ''VideoGame/MegaManX2'', the X-Hunters can be fought in secret rooms in the eight main levels. They don't die in these encounters, and are still the fortress bosses. Violen is the only one who had minimal difference in strategies between his two battles, while Serges now rides a giant machine, and Agile turns into a flying saucer-like vehicle.
*** In ''VideoGame/MegaManX3'', X can face Vile as an [[OptionalBoss optional encounter]], where he pilots a Kangaroo [[MiniMecha Ride Armor]]. If you don't destroy him in this encounter, he can be rematched at the fortress levels, now riding a bulkier Goliath Armor.
** It's tradition for the ''VideoGame/MegaManBattleNetwork'' and ''[[VideoGame/MegaManStarForce Star Force]]'' games that, once you beat a storyline boss, you can rematch it somewhere in the overworld (usually as PreExistingEncounters in unassuming spots), faster and with upgraded stats. Beating ''that'' form would upgrade the boss ''again'', and this time it's a BossInMookClothing because it's now part of the RandomEncounters.
** ''VideoGame/MegaManZero''
*** Downplayed with the Golems. In ''VideoGame/MegaManZero1'', a single Golem is the WarmupBoss, a StoneWall that Zero only managed to kill with the Z-Saber. ''VideoGame/MegaManZero2'' features elemental variants of the Golem, which have more attacks apiece, but in the process gets an elemental weakness.
*** The Guardians are regular (but CoDragons) bosses in the first game, but in the second, three of them get OneWingedAngel forms. The fourth died before he can showcase his own OneWingedAngel, but he does show up in ''VideoGame/MegaManZero3'' as an optional boss, faster and with more attack variety.
*** The Rainbow Devil is a fortress boss in both ''Zero 1'' and ''2''. In the latter, his DetachmentCombat attacks are now explosive, his [[DesperationAttack Ex Skill]], a MegatonPunch, is now a regular attack and replaced with a new one, where it temporarily becomes invincible.
*** Also from ''Zero 3'' is Omega. He is the intro boss, and only has simple attacks. Then, he absorbs the [[ArtifactOfDoom Dark Elf]] into himself, giving him more power; you'll fight him again as the FinalBoss, and the first phase is similar to the fight in the intro stage. However, after that, he goes OneWingedAngel on you, and the fight is no longer the same.
*** In the first BossBattle against Craft in ''VideoGame/MegaManZero4'', his Ex Skill is a WaveMotionGun that sweeps the arena. Just like the Rainbow Devil, in the second fight this becomes one of Craft's regular attacks, replaced by a new one: he flies to the air at the center of the field and fires his WaveMotionGun straight down, while also deploying a MacrossMissileMassacre.
* ''VideoGame/TheLegendOfHeroesTrails'': Recurring throughout the series is a BossBonanza that occurs in the FinalDungeon where the main party battles each of the major antagonists they've fought previously, now having new moves and more dangerous {{Limit Break}}s that could severely damage the team.
* ''VideoGame/HonkaiImpact3rd'': The boss "Herrscher of the Void" is fought in Chapter 8 where she attacks you with PowerOfTheVoid and [[SpikeShooter shooting big spikes at you]]. In chapter 9, she [[spoiler:absorbed Mei's Herrscher Core of Thunder and]] gains [[ShockAndAwe lightning powers]] that she'll use in the next boss fight against her, giving her new and upgraded attacks.
* Most famously used in the ''Franchise/{{Kirby}}'' series. Use of this dates back to the original ''VideoGame/KirbysDreamLand'' for the Gameboy, but it didn't become a mainstay for the series until ''VideoGame/KirbySuperStarUltra'' for the Nintendo DS.

* In ''VideoGame/PokemonBrilliantDiamondAndShiningPearl'', after becoming Champion and getting the National Dex, you can rematch Barry, the Gym Leaders, the Elite Four, and Cynthia in a greatly upgraded fashion. The Gym Leaders and Rivals all have a full team of 6 Pokémon with optimal [=IVs=] and maxed out [=EVs=], useful egg moves, beneficial Hidden Abilities, and items normally seen in competitive such as the Choice items, Life Orbs, and Focus Sashes.

* ''Franchise/SuperMarioBros'':
** ''VideoGame/PaperMarioTheThousandYearDoor'' has two stronger variants of [[OurDragonsAreDifferent Hooktail]], the first chapter boss. First is Gloomtail, Hooktail's elder brother, who sports a [[PurpleIsPowerful dark purple color scheme]] and a [[PoisonousPerson toxic]] BreathWeapon. The other is Bonetail, a SuperBoss who lives at the bottom of the [[BrutalBonusLevel Pit of 100 Trials]]. [[AmbiguousGender It]] is [[DemBones completely skeletal, as the name suggests]], [[MarathonBoss has the highest hit-point count in the game at a whopping 200]], and its BreathWeapon can randomly inflict one of almost every negative status effect in the game.
** The first ''VideoGame/SuperMarioGalaxy'' game has a rematch with [[TennisBoss King Kaliente]]. Unlike other examples, King Kaliente's attack pattern remains more-or-less the same, but the arena where you fight him is much more dangerous. It comprises platforms sinking into lava the longer you stand on them, has [[GoddamnBats lava bubbles]] chasing you around, [[ArsonMurderAndJaywalking and the King has a darker color scheme to boot.]]
** ''VideoGame/MarioAndLuigi'': ''[[VideoGame/MarioAndLuigiBowsersInsideStory Bowser's Inside Story]]'', ''[[VideoGame/MarioAndLuigiDreamTeam Dream Team]]'' and ''[[VideoGame/MarioAndLuigiPaperJam Paper Jam]]'' feature extra modes where the player can fight against stronger versions of all the bosses in the game (plus a SuperBoss at the end). In the former two games, these souped up versions of the bosses have different colors than the originals and are marked as "X" versions of them.
** ''VideoGame/SuperMarioOdyssey'': You can fight all of the bosses again in the [[spoiler: Mushroom Kingdom by jumping into paintings]]. In addition, you can fight the Broodals one more time on the [[spoiler: Dark Side of the moon]] in a BossRush. In all cases, the bosses have harder to dodge attacks or even change some mechanics of the fight completely. A harder version of Bowser can also be fought as a reward for [[OneHundredPercentCompletion collecting all of the Power Moons.]]
* ''VideoGame/PunchOut'' does this in every game except the SNES title:
** In the original arcade games, including the spin-off ''Arm Wrestling'', beating the FinalBoss doesn't end the game, but rather has you fight all the opponents again in a slightly different order. They are all much faster more powerful in these rematches and eventually will start one-shotting you.
** In the NES game, Piston Honda, Bald Bull, and Don Flamenco all return as opponents in the World Circuit. Their fighting styles have all been upgraded to cover much of their weaknesses, and Bald Bull has trained so that only a Star Punch or a counter to his Bull Charge can knock him down.
** The Wii game has Title Defense variants for all the boxers you've faced on the way to world champion. These rematches often involve gimmicks or attacks not present in your first fights with them (such as Glass Joe having protective headgear, Von Kaiser adding a OneHitKill move to his attack pattern, and Bald Bull only getting knocked down if he gets hit by a Star Punch), some can use fake-out attacks to throw off your dodging, and they all dodge your star punches if you don't stun them first.
* In ''VideoGame/SpiderManMilesMorales'', After Miles defeats Rhino at the start of the game, he returns donning armor [[spoiler:provided to him by Roxxon which enables him to resist Miles's Venom attacks and see Miles when he's invisible]].
* ''VideoGame/{{Undertale}}'':
** On a Genocide Route, [[spoiler: Undyne becomes Undyne the Undying when she refuses to die from your attack due to her determination. She]] gains new attack patterns, more health, and a higher attack stat.
** Subverted on a Genocide Route with [[spoiler:Mettaton. While he transforms into a new form, the player will always kill him in one hit and he will never attack, even if you skip your turn by [=ACTing=].]]

* ''Franchise/FinalFantasy'':
** ''VideoGame/FinalFantasyX2'': Experiment, a SuperBoss. The player can fight it at least once, and, to have a rematch, the player must find a key item called a Repair Manual then gather some parts from the Bikanel Digging Minigame until all its stats cap off at 5, with the Experiment changing form in the process.
** Normal trials and raids in ''VideoGame/FinalFantasyXIV'' are integrated into the story, and accordingly intended to be relatively easy to complete blind with a Pick Up Group. For the more dedicated players, there are the "Extreme" trials and "Savage" raids, which take the same enemies, beef up their damage output, increase the complexity of their mechanics, and demand higher DPS to clear. Accordingly, they also drop better loot.
* ''VideoGame/DemonCrawl'' has a rematch with Ego in the form of Beyond Ego. You have to use a specific emblem in beyond mode for it to appear, so there is no chance of doing it by accident.
* The ''Franchise/YokaiWatch'' games feature the Infinite Inferno, a postgame area that features a BossRush against bosses that are all recolored and powered up versions of the main story ones.
* ''Videogame/DiabloIII'':
** The rift guardians found in Nephalem Rift mode are souped-up versions of enemies and bosses fought in campaign mode.
** Certain enemies, known as "Keywardens", drop infernal machines that can be used to access realms where a pair of enhanced bosses from the campaign are waiting:
*** Odeg carries the Infernal Machine of Regret, unlocking a fight against stronger versions of the Skeleton King and Magdha the Witch.
*** Sokahr carries the Infernal Machine of Putridness, unlocking a fight against stronger versions of Rakanoth, Lord of Despair and Ghom, Lord of Gluttony.
*** Xah'rith carries the Infernal Machine of Terror, unlocking a fight against stronger versions of Zoltan Kulle and the Siegebreaker Assault Beast.
*** Nekarat carries the Infernal Machine of Fright, unlocking a fight against a stronger version of Diablo, who will periodically summon the bosses of the other realms to assist him.

* ''VideoGame/SpaceInvadersInfinityGene'': Whenever a boss from the campaign appears in an unlockable SecretLevel, there's a great likelihood that it will have more health, more aggressive attack patterns and/or [[FlunkyBoss appear alongside other enemies that weren't originally there.]] Stage X-29 is a particularly good example, being a much harder version of Stage 3-5, a BossRush featuring every major boss from sections 2 and 3 up to that point.
* ''VideoGame/AVeryLongRopeToTheTopOfTheSky'': Phobos, who is fought twice, all as {{Bonus Boss}}es, with the second time turning the fight into a WolfpackBoss battle by summoning two clones [[TurnsRed when at half health]].
* ''VideoGame/DonkeyKongCountry'':
** In the UsefulNotes/GameBoyAdvance remake of ''VideoGame/DonkeyKongCountry1'', most of the bosses have different attack patterns than their UsefulNotes/{{SNES}} counterparts:
*** Very Gnawty and Really Gnawty switch color palettes and attack slightly different. While Really Gnawty retains his attack pattern (more or less), Very Gnawty attacks by [[CollapsingCeilingBoss making stalactites fall from the ceiling]].
*** In "Bumble B Rumble", Queen B. now [[FlunkyBoss surrounds herself with Zingers after being hit, and you have to kill them before you can hit her again]].
*** In "Boss Dumb Drum", Dumb Drum no longer damages itself after you defeat its minions. Instead, TNT barrels appear after defeating a wave of enemies, which the Kongs must pick up and throw at the drum.
*** In "Necky's Revenge", [[DualBoss Master Necky Jr. and Sr. attack together]], and you have to kill them both. Defeating one will enrage the other.
** ''VideoGame/DonkeyKongCountryReturns'': The sixth boss of the game is Thugly, a [[PurpleIsPowerful purple]], {{heavily armored|Mook}} version of the first boss, Mugly. Compared to the first fight, Thugly is highly aggressive, much faster, and has a slew of all-new [[PlayingWithFire fire attacks]] that all serve to make him far a far more challenging opponent.
** ''VideoGame/DonkeyKong64'': The boss fights of Fungi Forest and Crystal Caves are rematches against Dogadon from Angry Aztec and Army Dillo from Jungle Japes respectively, both utilizing new attacks against you. Dogadon now creates a ShockwaveStomp when going to throw an exploding barrel at him, a near-unavoidable fire wall, and an additional phase where he makes the platform slowly sink into the lava below, requiring Chunky to defeat him within a limited time. Army Dillo obtains a pair of thrusters that [[GiantFlyer allow him to fly]] and unleash a Shockwave Stomp, [[MoreDakka and a giant]] [[{{BFG}} cannon on his back]] that fires a homing missile when on the ground and a barrage of {{Fireballs}} when in the air.
* ''VideoGame/FancyPantsAdventures'': The first boss of World 3 is the pirate Captain Rainbowbeard. He reappears in the final level, having dyed his hair and renamed himself Captain Manly Beard, with more powerful attacks and ninjas coming out of his beard for added difficulty.
* ''VideoGame/MetroidOtherM'': The second battle against [[MechanicalAbomination Nightmare]] has him use two new attacks, a BreathWeapon and firing a black hole that attracts all projectile weapons to it for a short period of time. Though he's not that much tougher since Samus obtains the Gravity Suit just before fighting him again.
* ''VideoGame/BravelyDefault'': Most if not all of the Asterisk holder bosses will have significantly boosted stats and have obtained new abilities to use against the party when fought again starting from Chapters 5 to 8. The same applies for the ones fought in ''VideoGame/BravelySecond'' as well.
* ''VideoGame/Splatoon2: Octo Expansion'' features rematches with "sanitized" versions of all the bosses from the main campaign, which can be found within the Deepsea Metro. These variants all share a [[PaletteSwap neon-green color scheme]], and feature several new and more aggressive attacks. Some of these rematches even change the nature of the fight completely -- for example, the Octo Samurai goes from a relatively straightforward DamageSpongeBoss to an inverted RingOutBoss whose attacks can knock players out of the arena.
* ''VideoGame/TheBattleCats'' has two examples. First, to unlock the [[SuperMode True Forms]] of the [[SuperpoweredEvilSide Crazed Cats]], you must defeat them first, and they serve as upgraded, remixed versions of their original fights. Second, [[spoiler:[[FinalBoss Mecha-Bun]] is a much stronger, faster version of the original Teacher Bun Bun. While the original was a WakeUpCallBoss that needed to be beaten if you wanted to get far in Stories of Legend, Mecha-Bun serves as the gatekeeper to the [[BrutalBonusLevel Uncanny Legends]].]]

* ''VideoGame/MonsterHunterGenerations'' introduces Deviant Monsters, which are monsters that have fought and survived many battles to become much stronger versions of themselves. Deviant Monsters carry new and more powerful attacks, the idea often being to take the monster's signature feature and exaggerate it to a threatening degree. As examples:
** Arzuros is an easy WarmUpBoss; other than being a [[BearsAreBadNews giant bear]] the only real threat it might pose is grabbing the player in a hold. Redhelm Arzuros, the first Deviant that the player will face, [[EstablishingSeriesMoment establishes just what kind of level the Deviants are on]] with a roar that actually stuns the player, a hide that requires very sharp weapons to penetrate, a five-swipe combo attack that's hard to evade, and souped-up single-swipe claw attacks that are strong enough to knock debris out of the ground or, if the player doesn't dodge the attack, push them back with a gust of wind.
** Rathian is already a formidable foe, being a textbook wyvern-type monster with breath attacks and a poisonous tail swipe attack. Dreadqueen Rathian makes much better use of her tail to introduce deadlier, harder-to-dodge tail swipes, and comes with a poison so strong that it chews through your health in seconds and cannot be negated with poison immunity; it can only be reduced to second-tier poison.
* ''VideoGame/TheBindingOfIsaac'': Many of the later bosses are in fact earlier bosses brought BackFromTheDead, with a new appearance and attack pattern. Not all of these bosses play the trope straight however, as some of them are considered to be easier than their living counterparts (such as The Forsaken when compared to its predecessor, The Haunt).
* ''VideoGame/NEOTheWorldEndsWithYou'' has upgraded forms of the Reaper bosses to face off against in Another Day, with a souped-up version of [[spoiler:Leo Cantus Armo]] serving as the ultimate SuperBoss.

* The Wii version of ''VideoGame/PunchOut'' has Title Defense variants for all the boxers you've faced on the way to world champion. These rematches often involve gimmicks or attacks not present in your first fights with them (such as Glass Joe having protective headgear, Von Kaiser adding a OneHitKill move to his attack pattern, and Bald Bull only getting knocked down if he gets hit by a Star Punch), some can use fake-out attacks to throw off your dodging, and they all dodge your star punches if you don't stun them first.

* ''Franchise/MegaMan''

* Most famously used in the ''Franchise/{{Kirby}}'' series. Use of this trope dates back to the original ''VideoGame/KirbysDreamLand'' for the Gameboy, but it didn't become a mainstay for the series until the UpdatedRerelease of ''VideoGame/KirbySuperStar'', ''VideoGame/KirbySuperStarUltra'' for the Nintendo DS.
* ''VideoGame/DevilMayCry3DantesAwakening'': Vergil is fought 3 times in a single playthrough: once at the seventh mission, once near the middle, and once as the FinalBoss. At first, he only fights with his katana, Yamato, and uses simple tactics. The second time you fight him, he has acquired the Beowulf gauntlets/greaves and fights you with it, though he sometimes shifts to Yamato again mid-fight; he also can use [[SuperMode Devil Trigger]]. In the final battle, he lost the Beowulf, but gained the [[{{BFS}} Force Edge]] and uses several attacks similar to yours (Dante's) alongside his new attacks with Yamato, and he also will use Devil Trigger mid-battle. In the harder difficulty modes, he'll also use [[OrbitingParticleShield Spiral Swords]] to make the fight trickier.

* ''VideoGame/PaperMarioTheThousandYearDoor'' has two stronger variants of [[OurDragonsAreDifferent Hooktail]], the first chapter boss. First is Gloomtail, Hooktail's elder brother, who sports a [[PurpleIsPowerful dark purple color scheme]] and a [[PoisonousPerson toxic]] BreathWeapon. The other is Bonetail, a SuperBoss who lives at the bottom of the [[BrutalBonusLevel Pit of 100 Trials]]. [[AmbiguousGender It]] is [[DemBones completely skeletal, as the name suggests]], [[MarathonBoss has the highest hit-point count in the game at a whopping 200]], and its BreathWeapon can randomly inflict one of almost every negative status effect in the game.
* The first ''VideoGame/SuperMarioGalaxy'' game has a rematch with [[TennisBoss King Kaliente]]. Unlike other examples, King Kaliente's attack pattern remains more-or-less the same, but the arena where you fight him is much more dangerous. It comprises platforms sinking into lava the longer you stand on them, has [[GoddamnBats lava bubbles]] chasing you around, [[ArsonMurderAndJaywalking and the King has a darker color scheme to boot.]]

* ''VideoGame/{{Undertale}}''

** Subverted on a Genocide Route with [[spoiler: Mettaton. While he transforms into a new form, the player will always kill him in one hit and he will never attack, even if you skip your turn by [=ACTing=].]]

* Normal trials and raids in ''VideoGame/FinalFantasyXIV'' are integrated into the story, and accordingly intended to be relatively easy to complete blind with a Pick Up Group. For the more dedicated players, there are the "Extreme" trials and "Savage" raids, which take the same enemies, beef up their damage output, increase the complexity of their mechanics, and demand higher DPS to clear. Accordingly, they also drop better loot.

* ''VideoGame/MarioAndLuigiBowsersInsideStory'', ''VideoGame/MarioAndLuigiDreamTeam'' and ''VideoGame/MarioAndLuigiPaperJam'' feature extra modes where the player can fight against stronger versions of all the bosses in the game (plus a SuperBoss at the end). In the former two games, these souped up versions of the bosses have different colors than the originals and are marked as "X" versions of them.
* The ''Franchise/YoKaiWatch'' games feature the Infinite Inferno, a postgame area that features a BossRush against bosses that are all recolored and powered up versions of the main story ones.

* ''VideoGame/SuperMarioOdyssey'': You can fight all of the bosses again in the [[spoiler: Mushroom Kingdom by jumping into paintings]]. In addition, you can fight the Broodals one more time on the [[spoiler: Dark Side of the moon]] in a BossRush. In all cases, the bosses have harder to dodge attacks or even change some mechanics of the fight completely.
** A harder version of Bowser can also be fought as a reward for [[OneHundredPercentCompletion collecting all of the Power Moons.]]

* VideoGame/DonkeyKongCountry:
** In the UsefulNotes/GameBoyAdvance remake of ''VideoGame/DonkeyKongCountry1'', most of the bosses have different attack patterns than their [[UsefulNotes/SuperNintendoEntertainmentSystem SNES]] counterparts:

* ''VideoGame/MetroidOtherM'': The second battle against [[GravityMaster Night]][[MechanicalAbomination mare]] has him use two new attacks, a BreathWeapon and firing a black hole that attracts all projectile weapons to it for a short period of time. Though he's not that much tougher since Samus obtains the Gravity Suit just before fighting him again.

* ''VideoGame/MonsterHunter Generations'' introduces Deviant Monsters, which are monsters that have fought and survived many battles to become much stronger versions of themselves. Deviant Monsters carry new and more powerful attacks, the idea often being to take the monster's signature feature and exaggerate it to a threatening degree. As examples:

* ''VideoGame/FinalFantasyX2'': Experiment, a SuperBoss. The player can fight it at least once, and, to have a rematch, the player must find a key item called a Repair Manual then gather some parts from the Bikanel Digging Minigame until all its stats cap off at 5, with the Experiment changing form in the process.

*** Very Gnawty and Really Gnawty switch places, meaning that Really Gnawty is the boss of Kongo Jungle and Very Gnawty is the boss of Gorilla Glacier. While Really Gnawty retains his attack pattern, Very Gnawty attacks by [[CollapsingCeilingBoss making stalactites fall from the ceiling]].

*** In "Boss Dumb Drum", Dumb Drum no longer damages himself after you defeat his minions. Instead, TNT barrels appear after defeating a wave of enemies, which the Kongs must pick up and throw at Drum.

*** Also from ''7'' is Bass. He is fought twice as a non-remarkable MiniBoss, first in the introductory level then in the first fortress level. In the second fortress level, however, he now turns into "Super Bass", where he combines with his robot wolf Treble in a form directly mirroring Mega Man's own Super Adapter upgrade.

* The Wii version of ''VideoGame/PunchOut'' has Title Defense variants for all the boxers you've faced on the way to world champion. These rematches often involve gimmicks or attacks not present in your first fights with them (such as Glass Joe having protective headgear, or Von Kaiser adding a OneHitKill move to his attack pattern), some can use fake-out attacks to throw off your dodging, and they all dodge your star punches if you don't stun them first.

* ''Videogame/HonkaiImpact3rd:'' The boss "Herrscher of the Void" is fought in Chapter 8 where she attacks you with PowerOfTheVoid and [[SpikeShooter shooting big spikes at you]]. In chapter 9, she [[spoiler:absorbed Mei's Herrscher Core of Thunder and]] gains [[ShockAndAwe lightning powers]] that she'll use in the next boss fight against her, giving her new and upgraded attacks.

* ''Videogame/DevilMayCry3:'' Vergil is fought 3 times in a single playthrough: once at the beginning of the game, once in the middle, and once as the FinalBoss. In the beginning, he only fights with his katana, Yamato, and using simple tactics. The second time you fight him, he has acquired the Beowulf gauntlets/greaves and fights you with it, though he sometimes shifts to Yamato again mid-fight; he also can use the [[SuperMode Devil Trigger]]. In the final battle, he lost the Beowulf, but gained the {{BFS}} Force Edge and uses several attacks similar to yours (Dante's) alongside his new attacks with Yamato, and he also will use Devil Trigger mid-battle. In the harder difficulties, he'll also use [[OrbitingParticleShield Spiral Swords]] to make the fight trickier.
