The video game version of RunTheGauntlet. A segment -- usually near the end of the game -- in which you're forced to fight a collection of previously-defeated bosses in sequence, often without a pause to heal or recollect spent resources in between. Depending on the game, the bosses may receive upgrades in order to remain challenging, or they may simply be a parade of {{Degraded Boss}}es that will drop like flies when faced with your improved arsenal, or they may be as deadly as they originally were in games where your character doesn't ''get'' an improved arsenal.

Occasionally this takes the form of a [[FinalExamBoss single enemy]] who simply mimics the other bosses' attack patterns. Some games feature the BossRush as an optional extra mode after the normal game is completed, rather than taking place near the end of the game.

It's a bonus if the BossRush is [[JustifiedTrope actually explained]] (if not, it could be considered as a special case of ArtifactMook instead). Part of the reason this trope exists is to reuse assets made for unique bosses on the already limited memory constraints of classic games. Most of the time, it's just an extra challenge.

SubTrope to BossBonanza, which covers any collection of bosses fought in sequence, previously-defeated or not.
[[IThoughtItMeant Not to be confused with]] RushBoss, or the WebGame [[http://paperdino.com/bossrush/ Boss Rush]] (which is an inversion). If a game is just more or less one big BossRush, it becomes a BossGame. Compare BossOnlyLevel, which is ''one'' boss that takes up a whole level. For examples of games having an option to replay boss fights outside the normal playthrough and out of any sequence, see ReplayMode.



* ''Franchise/TheLegendOfZelda'':
** Ganon sponsors them in two games:
*** Ganon's Tower in ''[[VideoGame/TheLegendOfZeldaALinkToThePast A Link to the Past]]'' features all four of the Light World bosses with upgrades (icy floor for the Armos Knights, traps in the room for the Lanmolas, a weird floor layout for Moldorm, and two false images for Agahnim). The GBA port features The Palace of the Four Sword, which has more difficult forms of the first four Dark World bosses as sub-bosses.
*** Ganon's Tower in ''[[VideoGame/TheLegendOfZeldaTheWindWaker The Wind Waker]]'' contains black-and-white repeats of every boss in the game bar two, complete with the added challenge of allowing you to use only the items you had available the first time you fought the boss in question. However, you do retain the double-damage Master Sword, so the first two bosses drop like flies once you manage to get to their weak spot (the HP of the other two is still high enough to last for as long as they did in the original fights).
** In ''[[VideoGame/TheLegendOfZeldaSpiritTracks Spirit Tracks]]'', there is a 50-rupee cost minigame where you go through a bunch of monsters, then get to fight the bosses of the game and Dark Link.
** In a lesser example, a hidden cave from Ikana Canyon in ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'' allows you to fight a series of {{Mini Boss}}es you had already defeated in order to gain a [[HeartContainer Piece of Heart]] (note that each mini-boss requires Link to have a minimum of hearts in his life meter to be challenged, ranging from 4 for the three Dinolfos to 16 for Garo Master). The Ikana route in the hide-and-seek area of the Moon does this as well, and not only has a Piece of Heart as a reward, but like all other routes it's also necessary to complete it if the player wants to obtain the Fierce Deity's Mask before facing the FinalBoss.
** Turtle Rock in ''[[VideoGame/TheLegendOfZeldaLinksAwakening Link's Awakening]]'' has this as well, with the sub-bosses from each of the first four levels and the sixth level reappearing in the dungeon as well as a brand new sub-boss.
** The UsefulNotes/Nintendo3DS VideoGameRemake of ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' has included the ability to fight previous bosses, and once each boss is refought, a boss rush is unlocked.
** In ''[[VideoGame/TheLegendOfZeldaSkywardSword Skyward Sword]]'':
*** Lanayru's Lightning Round is one of these. You get to pick a boss to fight at first -- win and you can carry on; but don't lose, or you'll have to start all over! The prize increases with each successive win, including a Piece of Heart, the game's [[InfinityPlusOneSword Infinity+1 Shield]], and more Rupees than you know what to do with. Note that you can only fight bosses you have already conquered (except the Bilocyte-infested Levias, who's oddly absent altogether) as well as the Horde blitz prior to fighting [[spoiler:Ghirahim III]]. In Hero Mode, you also get the privilege of facing [[spoiler:the Demon King, Demise]], who is [[NintendoHard all kinds of fun]]. For extra challenge, after the first boss, Lanayru picks the next at random.
*** In the last dungeon, there's a series of MiniBoss battles against two Moldorms, Dreadfuse, two Metal Shield Moblins, a group of Stalfos aided by Bokoblin Archers, and a Stalmaster aided by a group of Cursed Bokoblins.
** In ''[[VideoGame/TheLegendOfZeldaALinkBetweenWorlds A Link Between Worlds]]'', in order to unlock the pathway to the FinalBoss (Yuga) in Lorule Castle, Link has to defeat the bosses and minibosses whose life force keep the big red gate closed (Ball and Chain Trooper, Gigabari, Moldorm, Arrghus).
** ''VideoGame/HyruleWarriors'' has a stage like this. By collecting Gold Skulltulas, you can unlock a level where you face King Dodongo, Manhandla, Gohma, Argorok, the Imprisoned, and Ganon all at once.
** While ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' is very open-ended, if you [[spoiler:decide to ignore all the normal story progression and skip straight to [[TheVeryDefinitelyFinalDungeon Hyrule Castle]] to confront Ganon immediately, you'll have to fight through all four of the main dungeon bosses, the Blight Ganons, before you can even face Calamity Ganon]].
* In ''VideoGame/{{Okami}}'', you have to fight the first five bosses (Crimson Helm, Orochi, the Spider Queen, Blight, and Ninetails) again before you can proceed to the final boss battle ([[spoiler:the penultimate bosses, Lechku and Nechku, are not fought as you're without Oki, who was necessary to shoot them down in order to damage them]]). Another example is the third Bandit Spider Demon Gate, which includes a rematch against three tough mini-bosses ([[spoiler:up to three Evil Raos and two Wakas, all at the same time]]) previously seen through the main quest.
* ''VideoGame/{{Nightshade}}'' has a BossRush hall where you face off with all four bosses before the final battle with Sutekh. This could be avoided by finding four artifacts of power scattered through the city, and severing their connection to Sutekh. Each artifact protected would be one less boss to fight.
* ''VideoGame/StarTropics 2: Zoda's Revenge''. The second half of the final chapter is a boss rush of all the previous chapters (including the Scorpion mini-boss from Chapter 2). This is complete with black-and-white coloring for the bosses and backgrounds.
* ''VideoGame/OnePieceUnlimitedCruise'' has a couple of these, with two modes: a normal mode (in which item use is allowed), and a hard mode (no item for you).
* ''VideoGame/IllusionOfGaia'': While climbing the TowerOfBabel, each floor has a room which takes you to a previous Boss you must re-defeat in order to advance. The main differences are cosmetic; the rooms are all redesigned to resemble the Dark Spaces where you save your game and rest. The Bosses remain the same in strength, so your battles are (mostly) easier thanks to your upgrades since those initial battles. The only drawback comes in the form of more than one of those Bosses being ThatOneBoss earlier in the game. There's also the added difficulty that there are only savepoints next to the first boss battle in this final rush. After beating boss #1 (Castoth), the player can heal and save before heading up to face boss #2 (Viper). Then a quick trip back downstairs will let you use the same heal/save point as before. Unfortunately, you then pass through a one-way gate on the way further up the tower, and there are no further savepoints after that. This means that you have to fight the annoyingly difficult boss #3 (the Vampire Twins), the easy boss #4 (Sand Fanger), and the ''really'' annoyingly difficult boss #5 (the Mummy Queen) without any chance to save or heal between fights. You'd better still have a lot of those healing herbs in your inventory, you'll probably need them!
* ''VideoGame/CreepyCastle'':
** In The Depths scenario you may find one where you refight all the previous bosses of the scenario.
** In The Final Fist scenario you have to [[spoiler: fight shadow versions of bosses from earlier scenarios]] before fighting the [[FinalBoss final boss]].
* After you collect 100 mutations in ''VideoGame/{{Cubivore}}'', you go to the final run, which has you fighting ''every single boss from all 3 runs at the same time''. After that, you fight the [[TrueFinalBoss King of Beasts]] alongside the 4 other 6-limb Rage beasts.

[[folder:Action Game]]
* The House of Ruth level in ''VideoGame/EightEyes'' consists of rematches between six of the seven bosses from previous levels. The layout of each BossRoom is different from the ones in their own castles, so the player has to change up their tactics to survive the gauntlet.
* The final level of ''The Adventures of Batman & Robin'' (SNES, 1994) is just a boss rush of every villain Batman defeated in the previous levels. The level is named, appropriately enough, "The Gauntlet". Specifically, the villains you fight in this stage are (in order of appearance): Penguin, Scarecrow, Clayface, Catwoman, Man-Bat, and the Joker. Clayface and Man-Bat are not fought in any of the previous stages, and Poison Ivy, Two-Face, and the Riddler (who you ''do'' encounter as bosses in previous stages) don't show up in this level.
* ''VideoGame/GunstarHeroes'' (and the GBA sequel ''VideoGame/GunstarSuperHeroes'') has an interesting variation. While you do fight all the main boss characters you faced off with before, they now have either entirely new war machines, or very different attacks and tactics that you must adapt to. What's also interesting is that the entire level is seen through the BigBad's Control Station monitor, with all the bosses around him. When you defeat one, he directs another to move out and stop you.
* The last level of ''VideoGame/{{Chalk}}'' contains only weaker versions of past levels' end bosses.
* In ''VideoGame/{{Bleed}}'', the final stage has you fighting each boss from stages 1-5 in reverse order before facing the final boss. However, there is an added twist: [[spoiler:you will fight [[DualBoss TWO of each boss at the same time]]!]]
* The final level of ''VideoGame/{{Shatterhand}}'' involves fighting some of the bosses from previous levels.
* Beating all the stages in ''VideoGame/TowerFall''[='=]s ''Dark World'' expansion unlocks the "Dark Gauntlet" mode which serves as this.
* ''VideoGame/{{Contra}}'':
** The final stage of ''Contra III'' also does this, with returning bosses from the original ''Contra'' and ''Super Contra''.
** Stage 5-2 of ''Shattered Soldier''. After fighting Lance, you fight against remakes of several bosses from previous ''Contra'' games. Stage 6 combines this with a SequentialBoss.

[[folder:Beat 'Em Up]]
* ''VideoGame/DoubleDragon''
** In the arcade version of the first game, the player must fight against twin clones of the Mission 1 boss (a HeadSwap of Abobo) prior to the final battle, followed by three clones of the second boss (a head swap of the player) who fight alongside the final boss (Machine Gun Willy) as his bodyguards.
** In the NES version of the first game, the final area of Mission 4 consists of a grand hall where the player must fight against a group of seven Williams and twin versions of all the other enemies (Abobo, Chin, Linda and Rowper), followed by Machine Gun Willy and then the TrueFinalBoss [[spoiler:Billy's twin brother Jimmy.]]
** In the second arcade game, the player must fight against twin clones of all the previous bosses (Burnov, Abore and Chin) before the final boss fight with Willy and the player's own shadow.
** In the UsefulNotes/GameBoy version of ''Double Dragon II'', the player must fight against all the previous bosses (a boxer, [[HockeyMaskAndChainsaw a chainsaw-wielding]] [[Franchise/FridayThe13th Jason Voorhees]]-clone, a claw-wielding ninja, and a security guard with a club) before the final boss battle with Anderson.
** In ''Return of Double Dragon'', the Japanese version of ''Super Double Dragon'', the final room forces the player to fight all the previous bosses (Steve, Jackson, the Chen twins, [=McGwire=], and Carlem) before the final battle with Duke.
* Round 8 in ''VideoGame/StreetsOfRage'' forces the player to fight against all the previous bosses (Antonio, Souther, Abadede, Bongo, and Onihime and Yasha) before the final battle against Mr. X. While the bosses have less health this time, unlike in the regular rounds, the player cannot summon the bazooka-launching police backup to help them out (since the battle takes place inside a building).
* In ''[[VideoGame/TeenageMutantNinjaTurtlesTurtlesInTime Teenage Mutant Ninja Turtles: The Hyperstone Heist]]'', the fourth level (appropriately titled "The Gauntlet") features rematches against the first three level bosses (with an extra health bar each) before sending you against the level's real boss.
* Konami's ''VideoGame/XMen'' arcade game has you facing all of the bosses except Pyro ''plus'' two Magnetos, one being a disguised Mystique, one real, on Avalon.
* Several Creator/{{Konami}} arcade {{Beat Em Up}}s featured this. Not only does ''VideoGame/XMen'' have it (as mentioned above), ''VideoGame/CrimeFighters'' used a BossRush as a BonusLevelOfHell after the final stage, and ''VideoGame/MetamorphicForce'' featured one as the second-to-last stage (in an arena setting, no less) with a new boss at the end of the rush.
* ''VideoGame/ViewtifulJoe'' and its sequel each have a BossRush for their penultimate level. In the first game, they're statues of the bosses come to life. In the second, you fight an android that morphs into the other bosses. In both cases, the repeat bosses have more health than the originals.
* In ''VideoGame/XMenLegends 2'' you face both Apocalypse's four horsemen (all of whom you've already kicked the butts of) ''and'' Apocalypse himself. However, none are as hard as when you face them the first time. The sequel ''VideoGame/MarvelUltimateAlliance'' pulls the same trick but in a non-Boss Rush fashion with Doctor Doom being aided by an infinitively respawning Dark Fantastic Four.
* ''[[VideoGame/ScottPilgrim Scott Pilgrim vs. The World: The Game]]'' has a cheat code you can enter on the title screen to unlock the Boss Rush. You have to beat all 12 boss fights as fast as possible, with only one life, and almost none of the useable objects that show up in the main game except [[spoiler:the things Todd throws around with telekinesis, and the Power of Love sword]].
* ''VideoGame/MaximumCarnage'' was made of BossRush. First off, [[DegradedBoss a less powerful version of every non-super powered sub-boss would become a grunt in the next level]]. Then, the boss fights would feature an ever increasing number of super-powered bad guys who would reappear after defeat at the next boss fight. Finally, after a rooftop battle against about 8 true bosses at once, the next level was a Sub-BossRush featuring all of the grunts powered back up to their boss-fight level.
* The final stage in ''VideoGame/PanzerBandit'' is made exclusively of this, with all the bosses from the previous 7 stages coming back for a second round, this time apparently dying off for real as they fade out among explosions.
* ''VideoGame/DragonBallAdvanceAdventure'' has two. In Bosses on Parade, you fight all of the platformer bosses in sequential order (except the flying battles if you're not playing as Goku or Krillin), with a rest area between battles where you have the option to use one of your limited supply of 4 full-healing items. In the One-on-One Survival mode, you start with a three-layer lifebar and fight all the One-on-One characters, including a duplicate of whoever you selected.
* The final stage of ''VideoGame/BadDudes'' had you fighting through all the bosses again, though Karnov and Animal (the stage 4 boss) are both zombified ([[AllThereInTheManual according to the end credits of the Japanese version]], which list those two and only those two as different enemies).
* In ''VideoGame/MadStalkerFullMetalForce''[='=]s final stage, you face off against boss rush of the all of the previously beaten bosses save for [[FinalBoss Rising Dog]] in succession. Silpheed and Prisoner-β will also have {{flunk|yBoss}}ies aiding them during the re-match.
* Unlocked as an extra for beating the story mode of ''VideoGame/JusticeLeagueHeroesTheFlash''.

[[folder:Eastern RPG]]
* ''VideoGame/BreathOfFireIII'' pulls this one near the end of the game. One of the last areas you have to wander through has multiple rooms, many of which hold previous bosses under the name "Sample ##" (each boss had a different number; presumably, the new name scheme was an excuse to not show the HP of bosses that haven't changed one bit). Most of the weaker bosses simply came in groups rather than alone (for example, the game's first boss, Nue, came in a group of 3, but wasn't any stronger), and a few received upgrades (such as the Stallion boss, which was now 3 monsters instead of one, and each one now used and absorbed a specific element). There was even a new boss to fight (though still going by the "Sample" naming scheme), one resembling a giant bird (using the sprite of the Basilisk {{mook}} from the [[VideoGame/BreathOfFireII the previous game]]), which is supposedly a copy of a boss that was cut from the final game.
* The entire last area of ''VideoGame/BreathOfFireDragonQuarter'', as there is no chance to save once you're in.
* The first form of Lavos in ''VideoGame/ChronoTrigger'' mimics nine previously-fought bosses in sequence. The repeats receive [[VillainForgotToLevelGrind no updates in stats at all]], so the first several [[CurbStompBattle go down in one hit]], even on your first playthrough. It helps that it [[LetsFightLikeGentlemen allows you to heal and swap party members]] between each iteration, though it [[GuideDangIt doesn't go out of its way to let you know about this]].
* In ''VideoGame/DigitalDevilSaga 2'', [[BonusBoss a sidequest]] allows you to fight the four archangels Uriel, Raphael, Gabriel, and Michael in a certain area. The first three you fight individually, but in the final fight you have to kill them again before facing Michael. In addition, the final dungeon has an interesting case overlapping with BossBonanza - [[spoiler:you have to fight four bosses from the first game: Harley/Hayagriva, Bat/Camazotz, Mick/Rahu, and Varin/Beck/Ravana]].
* An odd version of this occurs in the final part of ''VideoGame/DragonQuestIII''; before getting to fight the final boss, you have to fight his minions; three nasty midbosses. However, instead of being easily-defeated former bosses, these guys are amped-up recolors who can and will beat the crap out of you, inevitably leaving you weakened for the final boss. It doesn't help that they ''respawn''; if you die and get booted back to town, or so much as ''leave the room'', you'll have to fight through them all over again.
* ''VideoGame/FinalFantasyI'' had each of the Four Fiends occur as [[MiniBoss pseudobosses]] in the final dungeon. However, unlike other Boss Rushes, they were actually interspersed throughout the temple, at a series of specific (unavoidable) squares. If you traveled over those squares repeatedly, you'd have to fight them again! Apparently to prevent [[GameBreaker easy leveling]], the bosses all had low experience gains. In addition, the Boss Rush was slightly explained by [[spoiler:taking place 2000 years in the past.]]
** As an homage to this, ''VideoGame/FinalFantasyIX'' does the same thing in Memoria, where the four elemental fiends are encountered at various points in the level. The big difference is that only one of the four previous encounters with the fiends were under player control. Expanding even further on the concept, the very last area in the game features endless copies of these bosses as the only random encounters in the area. Each boss improves slightly so their weaknesses are removed and get new spells. This led to a situation where the first major boss would suddenly use NUKE on you.
* ''VideoGame/FinalFantasyIV'' features repeats of the Four Elemental Lords in the Giant of Babel. Their stats are improved, but they lose a lot of their unique abilities that made them ''really'' challenging. Unless you're playing the DS remake, in which case they have lost ''nothing''.
* ''VideoGame/FinalFantasyV'', In the GBA port, the Cloister of the Dead inside the Sealed Temple, which is unlocked after defeating Enuo, features most bosses from the game to be fought in a succession of waves, all of them slightly altered to adjust the challenge.
* ''VideoGame/FinalFantasyVI'', in its version for the GBA, has the Soul Shrine, a place where the souls of all the enemies go after being defeated. In order to appease them, you have to fight 128 consecutive battles, with only 5 breaks in between. These fights are random, and they can include the [[ComMons commonest of the foes]], but you could end up fighting ThatOneBoss as well. Repeatedly. Regardless, for the final 9 battles, you'll face the 8 Dragons after they've taken their steroids, and their angry daddy, the powerful and almighty [[BonusBoss Kaiser Dragon]]. Of course, you will be [[BraggingRightsReward rewarded accordingly]].
* The Special Match in the Battle Square in ''VideoGame/FinalFantasyVII'' has elements of a Boss Rush. Three of the first four enemies are seen as final enemies in the Battle Square's normal matches (and also as normal monsters elsewhere), while the 5th and 8th enemies are bona fide storyline bosses.
* ''VideoGame/FinalFantasyX'': The ending sequence, which begins with [[ThatOneBoss Braska's Final Aeon]], then all of Yuna's Aeons - one after the other - and finally, Yu Yevon. The fact that you have Permanent Auto-Life throughout the latter two parts takes away from the spectacle somewhat.
* In ''VideoGame/FinalFantasyCrystalChroniclesEchoesOfTime'', once you approach the game, allows you to fight the bosses from the previous game in the series, ''Ring of Fates'', although you can stop between each battle, and come back and face any of them again at any time.
* ''VideoGame/FinalFantasyBraveExvius'' has the March of the Beasts, available on the Chamber of the Fallen. It is a 9-round dungeon requiring 30 energy, and Lapis can not be used to continue, meaning you only have one attempt to complete it. It features a gauntlet of bosses found in the main story, with increased HP and ATK. Completing the dungeon will grant the Demon Mail, which gives 30% resistance to Dark elemental damage.
* The penultimate area of ''VideoGame/HolyUmbrella'' has a roulette wheel of six previous bosses, followed after a cutscene by a rematch with [[TheDragon Donderasaurus]].
* ''VideoGame/LegendOfLegaia'' has one of the most sadistic {{Boss Rush}}es in history. You're forced to fight three siblings of varying difficulty, one-on-one, with an equivalent fighter on your own team, before having to fight Koru - who doesn't do a great deal of damage, but comes with an inbuilt timer which blows him up in five turns, ending the game. Thankfully, there is a chance to heal and save between the Delilases and Koru. The Master Course of the [[InevitableTournament arena]] also qualifies, though it is thankfully optional.
* The main ''VideoGame/{{Lufia}}'' games have you fight all of the Sinistrals on [[TheVeryDefinitelyFinalDungeon Doom Island]], including rematches of previously-defeated Sinistrals. Justified in that the Sinistral of Death has the power to revive fallen Sinistrals.
* The Tower of Dread in ''VideoGame/{{Miitopia}}'' has the Miis fight [[spoiler:the powerful bosses of each of the eight New Lumos districts in a row]]. There are no breaks between the battles, and therefore the Sprinkles do CANNOT be refilled.
* ''VideoGame/MachinaOfThePlanetTreePlanetRuler'': In the final dungeon, Felmut creates a seal on a portal that can only be lifted by fighting stronger versions of every non-humanoid boss.
* The ''VideoGame/MonsterHunter'' games have the "Epic/Marathon" Hunting Quests. Made particularly difficult because you can't change your weapon mid-hunt and each monster is easier/harder to deal with using certain weapons more than others (e.g Dual swords on a Plesioth is pain incarnate; a bow or bowgun with Pierce shots will make sashimi out of one). In ''3 Ultimate'', these missions become the largest part of the final High Rank chapter (9 stars) in the Village route, and the most ''common'' in all of G Rank in the Guild route. In ''4 Ultimate'', many quests of this kind have the monsters infected by the Frenzy Virus, making them more difficult to hunt. To ease the pain, large monsters in multi-monster quests tend to have less health; a monster that typically takes you 15 minutes to slay normally can take only 10 minutes or even five.
* ''Franchise/{{Pokemon}}'':
** In ''VideoGame/PokemonBlackAndWhite2'', there's the Pokemon World Tournament, where you go into a bracket tournament against a particular region's set of Gym Leaders. There's also the World Leaders Tournament, a bigger tournament with opponents from all regions, and the Champions Tournament.
** In the ROM Hacks ''Sacred Gold and Storm Silver'', there's a special Boss Rush in the Fighting Dojo. You face basically every boss from the game: all 16 gym leaders, the 4 Rocket Admins, TheRival, the Elite Four, [[spoiler:Giovanni]], Lance, and Red.
* ''VideoGame/RecettearAnItemShopsTale'' has a Boss Rush of each dungeon's roster unlocked for beating it - useful for farming boss drops. The BonusDungeon also features a rush of ''every boss fight in the game'' - all 100+ of them.
* ''VideoGame/RivieraThePromisedLand'' has one in the final section of the game where the player needs to fight 5 Dark Progenitors, basically boss of previous chapters (except [[spoiler:Ledah]]) before facing [[spoiler:Hector]], and then face [[spoiler:Seth-Ra]].
* Near the End of Red's Scenario in ''VideoGame/SagaFrontier'', you have to fight all of the major bosses again (Each has double the Initial HP they had in the first battle.) [[spoiler:You do fight [=MBlack 3=], but that is after the main BossRush.]]
* ''VideoGame/SecretOfMana'' comes close to this trope with the Pure Land, an area near the end of the game featuring six bosses, many of them [[PaletteSwap upgraded versions]] of earlier bosses. While you ''can'' leave at any time to heal or restock, doing so forces you to [[{{Backtracking}} retrace your steps]] through [[ThatOneLevel a tough area]] replete with [[DemonicSpider powerful enemies]] in order to make additional progress.
* A series of events hardly hinted at in ''VideoGame/TheWorldEndsWithYou'' causes Another Day's Neku to run into the main game's Joshua - with Another Day's Joshua in tow! It's then that main Joshua challenges Another Neku to an 11-reduction chain battle against just about every boss in the game. The only worthwhile prize to be gained from this (asides from a chance at the bosses' own individual drops multiplied by eleven, useful if you're having difficulty chaining them elsewhere) is five 10K Yen pins and the Angel Feather, which is AwesomeButImpractical, but at least it's redoable.
* ''VideoGame/JojosBizarreAdventureThe7thStandUser'' has a boss rush that can be triggered by running into an NPC in the final town after discovering Dio's mansion. It consists of all the Tarot bosses (except Kakyoin and Polnareff, natch) with higher stats and, in a few cases, new attacks and different gimmicks. For example, Tower of Gray has an attack that is normally exclusive to hard mode, and the battle with Hanged Man is completely different, catapulting it into ThatOneBoss territory.
* The start of the hidden story path in ''VideoGame/WayOfTheSamurai4'' is this. If you managed to initiate the requirements of the hidden path, you will fight in this order: Akagi, Melinda, Kotobuki and the three Kinugawa sisters. What makes it difficult, is that you probably do not have access to healing items, as this fight takes place at the start of the game. The only healing items you might have are dropped by Prajna members fought during the tutorial fight.
* ''VideoGame/{{Lunarosse}}'' has three boss rushes. You fight one midway through the game, with the other two located in a hidden dungeon and as post-game content. Each one ends with a unique enemy.
* Starting with ''VideoGame/MarioAndLuigiBowsersInsideStory'', the ''VideoGame/MarioAndLuigi'' series has featured an area where you can face off against stronger versions of the game's bosses, with limited items and a turn limit imposed on you. You can face each boss individually, or face them all in a row ending with a BonusBoss fight against either an incredibly powered up version of Bowser known as "Bowser X" (''Bowser's Inside Story''), [[spoiler:Bowser Jr.]] (''VideoGame/MarioAndLuigiDreamTeam''), or [[spoiler:Dry Bowser]] (''VideoGame/MarioAndLuigiPaperJam''). ''Dream Team'' also features an alternate mode where you face off against the game's Giant Bosses again.
* ''Franchise/MegaMan'':
** All of the ''VideoGame/MegaManBattleNetwork'' games aside from the first and fourth, despite being [=RPGs=], have a boss rush towards the end of the main story that is split into multiple sections.
*** The sixth game in particular has two, with the second being a repeatable straight boss rush in the BonusDungeon that is required in order to challenge the BonusBoss again. Similarly, the fourth and fifth games have the same setup, where the six bosses you gained Double Souls have dark counterparts that must be defeated to reach the BonusBoss. In the fourth game, it's one-time-only fights, which eventually lead to a battle with Mega Man's Dark Soul. In the fifth game, going off to face the Chaos Lord warrants a rematch with the Dark Soul Navis each time you return to fight again -- though depending on the average time it takes to defeat the Navis, Chaos Lord will assume the form of Nebula Grey, Bass, or Mega Man's Dark Soul.
*** The ''Battle Network'' games also had a habit of throwing waves of viruses at you in gauntlet-style battles, the circumstances depending on the situation involved. Sometimes, the virus fights could be as lengthy as ''20'' battles in a row! Yes, that's right -- '''''TWENTY!'''''
*** The third ''Battle Network'' had two unique situations of boss-rushing. One involved earning ranks to rise up in status in the Undernet, where Beastman shows up suddenly for a rematch, getting deleted again earlier than the other enemy Navis and not during the final stages of the game. To prevent a third fight, Wily terminates his operator, Inukai. The other instance of boss-rush beyond the norm is a series of battles against 15 Omega Navis, the strongest forms of all the Navis in the game, including post-game bosses (save for BonusBoss Punk), accessed by a secret code when you have surmounted five stars. These fights are punctuated with 3 battles against Omega-level viruses, then a battle against the Omega Navis. To find them, you have to stumble upon their hidden data on the Net. Beating them and earning seven stars causes FinalBoss Alpha to morph into a respective Omega form.
*** Although the first game made the player go through similar dungeons from earlier in the game. The only thing that was missing was a boss at the end of them. And the 4th game only had only 2 non-final bosses you were guaranteed to face, with one of those bosses not really counting as a boss fight (until the post-endgame anyways) and the other boss isn't ever faced until the room before the final boss.
** The picture at the top of this trope's page + Mega Man 2 = [[http://www.youtube.com/watch?v=LQBU4ZfA_qY Rockman 2 (Ippatsu) Neta]]. And yes, it is beatable. (Another E-tank, onii-chan? Maybe that's bad to say, for reasons.)
** ''VideoGame/MegaManStarForce'' has all the FM-ians revived to face off with you as you progress through to get to BigBad Cepheus -- save for Gemini, who shows up earlier for a rematch. How they can assume the forms they took when merging with a human by themselves is {{handwave}}d by the fact they can copy the memory of these forms in their bodies, then mimic them perfectly.
** In ''Star Force 2'', there are two boss rushes of sorts. The first is the normal one where you fight all the bosses who aren't your friends (the usual type,) while the second is in the [[BadFuture Bonus]] [[BonusDungeon Dungeon]], where you fight heavily upgraded versions of nearly every boss, (friends included,) as well as some new ones, ending with the BonusBoss. ''Star Force 3'' also does the same thing.
** ''VideoGame/MegaManXCommandMission'' has these as well, despite being an RPG, like the above examples. It's handwaved into the Robots' "DNA" having been absorbed by the BigBad and the BossRush versions not being the original bosses.
* ''VideoGame/LiveALive'' has two, both being unique twists on the trope that depend on whether or not you choose [[spoiler:Oersted]] as the final protagonist:
** Choose one of the first seven characters, and [[spoiler:the Boss Rush actually becomes the True Final Boss. If you get everyone's ultimate weapons, beat Odio, and spare Oersted, Oersted will come back and pit everyone against their respective main boss. When all seven are beaten, Oersted finally dies]].
** Choose [[spoiler:Oersted, and the entire final chapter is an inverted Boss Rush. Since the first seven bosses are manifestations of Oersted's hatred, he can take control of them, letting the player play as the bosses against the protagonists. There are two ways to win: the traditional beat them all method, or by letting a boss get to low health, which allows you to use Armageddon]].
* The MonsterArena in ''VideoGame/GoldenSun: The Lost Age'' can easily become this if you have defeated every boss there is. The normal bosses aren't ''that'' hard, but try surviving when there comes BonusBoss after BonusBoss. Or easier said, try surviving when ''Dullahan'' comes.
* Before the final confrontation in ''VideoGame/GrandiaII'', you have to fight most of the pieces of Valmar you have defeated so far. Somehow explained, since [[spoiler:BigBad Zera]] absorbed them.
* In ''VideoGame/{{Xenoblade}}'', the stretch before the final boss places phantoms of Xord, Metal Face, Jade Face, and the Sani Telethia in your way. Oddly, you're allowed to simply run past them if you're not in the mood for fighting.
* ''VideoGame/KingdomHeartsBirthBySleep'' has the "Villains Vendetta" event at the Mirage Arena, which is a battle against eight Unversed bosses (well, seven Unversed and the Ice Colossus, actually) from all three stories.
* ''VideoGame/KingdomHearts358DaysOver2'': Mission 89 on Day 353 has Roxas going around Twilight Town to take down 6 powerful Heartless: Gigas Shadow, Poison Plant, Stalwart Blade, Orcus, Veil Lizard, and Power Armor. There's also an [[BonusBoss optional fight]] against the draconic Dustflier, the strongest enemy in the game, that shows up in front of the Clock Tower once the other 6 have been defeated.
* ''VideoGame/KingdomHearts02BirthBySleepAFragmentaryPassage'' has one, unlocked by opening 12 zodiac chests. It starts off with a Darkside, two swarms of Heartless, and a Demon Tower. But the final opponent? Say hello to [[spoiler:[[BonusBoss an even stronger version]] of [[MirrorBoss Phantom Aqua]]. She's by far the hardest boss of the game. Be prepared for hours of rage.]]
* ''VideoGame/BravelyDefault'' has one in the last chapter of the game, [[spoiler:where ''every human boss you've ever fought'' comes back to challenge you ''in teams of four'']]. Also, the BossRush is [[JustifiedTrope entirely]] justified, and there's boss banter between the bosses themselves as to ''why'' they're all working together and why each team was formed with certain members -- for instance, one team specializes in [[spoiler:inflicting status ailments]], with the leader of the team capable of dishing out ''incredible'' amounts of damage [[spoiler:dependent on such status ailments being in place]]. These aren't {{Degraded Boss}}es, either. If you go in unprepared and without a strategy, ''especially'' in [[NintendoHard Hard Mode]], prepare to be curb-stomped. It's an absolutely gruelling gauntlet, although you are allowed to heal in between.
* ''VideoGame/DigimonWorldDawnDusk'' features a post-final-boss quest where you have to go through a new area featuring stronger wild encounters than any you have faced before, only to end up with a boss rush involving SEVEN back-to-back battles, of which two are against a pair of Digimon, while the rest are against only one (tellingly, most of them are either {{final boss}}es or {{eleventh hour superpower}}s from the anime or manga). [[spoiler: Omegamon was nasty thanks to Royal Slash, and the fact he was not alone, then there's Dukemon Crimson Mode at the end who not only hits like a truck, but takes quite a while to bring down too]]. If THAT wasn't enough, there's another boss rush quest after you've done several other things, including the boss rush just mentioned. This time, it's 5 battles, each against 1-3 digimon, the last one being against a digimon that has obscenely high defences and resistances to most things, leading to what is a MarathonBoss (called [[spoiler: Chronomon Holy Mode, a bonus boss who is the more powerful version of Digimon World DS's final boss, in which he also turns up as a bonus boss]]) if you don't have [[spoiler: darkness attacks to exploit its weakest resistance]].
* ''VideoGame/DigimonWorldDS'' does this with the final quest. First, you have to beat six bosses scattered across the game's later dungeons. Following that, you can finally travel to the final dungeon and encounter the TrueFinalBoss, at which point [[spoiler:the other six bosses, or superpowered versions of them, arrive and you fight them, one after the other, and the final boss]].
* The final boss battle of ''VideoGame/DigimonWorld3'' is essentially one of these, as it's [[spoiler:[[GlassCannon Nanomon]], [[ThatOneBoss Valvemon]] and [[GiantSpider Armagemon]] under the command of a Tamer]].
* Chapter 40 of ''VideoGame/TheLastStory'' has rematches against Berith (first fought in Chapter 33), Zepha and Zesha (fought together in Chapter 35, fought separately this time), Zangurak (first fought in chapter 10) and [[spoiler:Dagran]] as the FinalBoss. Five bosses in total.
* ''VideoGame/TheInfynPrism'' has the Knowledge Vault, a giant tower where the player must fight every boss in the game, save the [[WolfpackBoss Terracotta Kings]], and the final boss. InUniverse, its size varies for each entrant, as the tower draws on the entrants memories and make the monsters stronger, creating a more powerful boss. However, this is only for show as the tower's order doesn't change for the player.
* The [[TheVeryDefinitelyFinalDungeon Primal Cataract]] from ''VideoGame/SandsOfDestruction'' is populated by mechanical reconstructions of the various beastlords you've fought. They're RandomEncounters, though, so you probably won't encounter them in order and will almost definitely encounter them more than once - they're {{Degraded Boss}}es, but this is the only place you fight them and they're the only enemies in the area, making the level a variation of the traditional boss rush.
* Chapter 61 of ''VideoGame/GranblueFantasy'' has you fighting five bosses in its four sections. Lecia and Katarina fight Gandharva, Rosetta and Io fight Fenrir, Eugen, Rackam and the main character fight Leviathan Malice, and then the party comes together to fight Leviathan Malice (again) and Mithra Malice back to back.

[[folder:Fighting Game]]
* ''VideoGame/SuperSmashBros'':
** The All-star mode in ''Melee'', in which the player fights all characters in a random order, in matches that start in 1-vs.-1 mode, go through 1-vs.-2, then 1-vs.-3 and finishes with a duel against 25 Mr. Game & Watches. ''Brawl'' features this mode again, sorting the character order by the date of origin of their franchises, but also has an actual BossRush mode in the Stadium menu with the bosses from the Subspace Emissary. In ''4'', the order is based on the date of origin of the ''characters'' themselves (straight in the 3DS version, reverse in the Wii U version).
** Also in ''Brawl'', during the final level of the Subspace Emissary, The Great Maze, there's a Boss Rush which is a combination of the All-Star and BossRush modes, seeing as you have to not only fight all characters gained in the story but all the bosses as well. The Great Maze is also a ''Game'' Rush, since not only you have to fight all the other characters and the bosses gained and beaten previously but you also go through bits of most of the levels previously cleared in a single {{Metroidvania}} level. [[http://www.smashbros.com/en_us/gamemode/modea/modea17.html This page]] actually explains this part of the game, saying that the Great Maze is assembled with the pieces of the world taken to Subspace with the Subspace Bombs, and that the revived bosses and shadowy clones are the result of the Subspace Army's extensive analysis.
** The final co-op Event Match in ''Brawl'' and ''Wii U'' is two players against the game's playable roster, similar to All-Star Mode minus the breaks or recovery opportunities.
* The final battle of [[BigBad Nowel's]] route in ''VideoGame/MagicalBattleArena'' has you fighting everyone you've fought along the way, except the [[Anime/MagicalGirlLyricalNanohaStrikers Gadget Drones]] and [[MirrorMatch your clones]]. The bad: Since this is a FightingGame, Nowel is still as strong as she was then as she is now. The worse: You have to fight all of them at the same time with no allies. The worst: They're not handicapped in any way. [[ThatOneBoss Have fun]]!
* ''[[VideoGame/SoulSeries Soulcalibur V]]'' has "Legendary Souls" mode, where players fight seven hard bosses (Kilik, Nightmare, Siegfried, Cervantes, Edge Master, Elysium and Algol) in quick succession.
* ''[[VideoGame/{{Tekken}} Tekken Tag Tournament 2]]'' has three consecutive in the Arcade Mode. The four bosses are also {{Final Boss}}es in the ''Tekken'' series. The first battle is a tag battle with Heihachi Mishima[[note]]FinalBoss in ''Tekken 1'' and ''Tekken 4''[[/note]] and his father, Jinpachi Mishima[[note]]FinalBoss in ''Tekken 5'' and ''Tekken 5: Dark Resurrection''[[/note]]. The second one is with True Ogre[[note]]FinalBoss in ''Tekken 3''[[/note]], and the last one is with Jun Kazama who transforms into Unknown[[note]]Unknown is the FinalBoss in ''Tag Tournament 1''[[/note]] if you defeat her first.
* ''VideoGame/TheKingOfFighters'' has a variation: one of the 3-man teams is all known bosses, [[VideoGame/FatalFury Geese Howard, Wolfgang Krauser]] and [[VideoGame/ArtOfFighting Mr. Big.]] Later teams would feature original boss-level characters like Chris, Shermie and Yashiro.

[[folder:First-Person Shooter]]
* Happens at the end of ''VideoGame/{{Blood}}'', where you have to fight the three bosses you defeated earlier before finally facing the BigBad.
* At the climax of ''VideoGame/HalfLife2: Episode Two'', you have to face a small army of tripodal Striders (which served as bosses in the two previous games), and two to three Hunters (which were used as bosses earlier in the game) accompany each one! This is made significantly easier than it sounds, though, since with a bit of skill you can one-hit kill both of them.
* The final stage in ''VideoGame/KensLabyrinth'' has you fighting the bosses of episodes 1 and 2 before fighting [[FinalBoss Ken]].
* The final DLC of ''VideoGame/{{Borderlands}}'' brings back 2 bosses from earlier DLC, along with TheUnfought from the main game as mission bosses. Before fighting the game's final boss, you must first defeat previous three in rapid succession. Much to [[spoiler:General Knoxx]]'s dismay, as he's been longing for death for more than an entire DLC by now.
* In the third-to-last level of ''VideoGame/Prey2006'', just before you fight the DiscOneFinalBoss, you're pitted in an arena fight against practically every enemy type in the game, including the game's previous two boss characters.
* The two penultimate levels of ''VideoGame/BatmanDoom'' take place in the Arkham Asylum in the middle of an outbreak (mirroring the part from the comic book storyline ''ComicBook/{{Knightfall}}''). All the inmates from Batman's RoguesGallery -- which is to say, the bosses you've fought throughout the game -- are fought one by one throughout these two levels.
* In the last level of ''VideoGame/WillRock'' (Mount Olympus) you have to fight waves of enemies, among the others several [[DegradedBoss Cyclops and Eaphesti]], [[GiantSpaceFleaFromNowhere a revived Medusa]] and [[BigBad finally Zeus himself.]]

[[folder:Hack and Slash]]
* ''VideoGame/DevilMayCry 3'' and ''4'' have one level almost entirely devoted to this. Then again, they ARE Capcom games. Also, the penultimate boss of Dante's scenario in ''2'' is a mishmash of most of the bosses you've fought up till that point, including one from the first game.
* In ''VideoGame/TheForceUnleashed'', the fight with Proxy resembles this. Every few times you hit him, he changes into a different boss that you have fought, before finally settling on Darth Maul.
* The PSN download game ''VideoGame/{{Malicious}}'' is pretty much a boss rush game masquerading as a ''VideoGame/DynastyWarriors'' style hack & slash - it dumps you straight in a boss battle when you select a level and laughs as you run for your life. It only doesn't count as a BossGame because there ''are'' mooks in the stage and you ''are'' supposed to kill a whole lot of them before seriously engaging the boss. Or you can try your luck, but that tends to end badly.
* ''VideoGame/{{Bayonetta}}'' has degraded bosses show up as early as two levels after you kill the bosses they're based on, but in the final lengthy level of the game you wind up fighting all of them over the course of the stage, as well as BossInMookClothing Golem and Joy(s).

[[folder:Light Gun Game]]
* ''VideoGame/HouseOfTheDead'':
** The first game has you fighting previously fought bosses again. During the last level, you face off with the bosses of the first two levels. Chariot is the same, though Hanged Man is a little easier.
** In ''House Of The Dead 2'', you have ''two'' types of {{Boss Rush}}es in the game. You battle the first three bosses of the game again, as well as the final boss of the ''first'' game, throughout the last two levels, with some variations. Finally, when fighting the last boss, Emperor, his second attack strategy is actually to summon up transparent clones of the first four bosses, who attack once before fading away.

* In ''VideoGame/CityOfHeroes'' you can fight the archvillains of the Council individually in different parts of the game. In ''VideoGame/CityOfVillains'' you fight a gauntlet of them all in a single mission near the end of the game. Interestingly, you face the toughest ones early on in the boss rush.
** "End of the game" meaning that this challenge is not available to the player until they reach level 45 in a MMO that has 50 levels.
** The Lord Recluse Strike Force in the level 45-50 range of VideoGame/CityOfVillains features '''three''' boss rushes in which you fight all of the present elite Heroes simultaneously. Of course, since this is a MMO, "simultaneously" just means "be careful with the pulls".
** Its heroic counterpart, the Statesman Task Force, has ''three'' boss rushes, each one higher up the Arachnos chain of command. The middle one takes it literally, as players have to defeat each member of the QuirkyMinibossSquad at a time to get to the next floor, before about a billion {{Mooks}} catch up.
* ''VideoGame/MapleStory'' has Mu Lung Dojo, where you fight 39 various area and party quest bosses in order of weakest to strongest, with another boss at the end.
* ''VideoGame/{{Vindictus}}'' has battlequest ''Prepare for Counterattack'' in the first boat and ''The Unveiling Truth'' in the second. The bosses in these spawn on a timer 3 minutes apart, which means that if any fight lasts longer than that it becomes a WolfpackBoss.
* In ''VideoGame/WorldOfWarcraft'', Crusader's Coliseum features this in both 5-man dungeon form and 10/25-man raid form. You're given time to heal/rebuff/resurrect between each fight, though. The first fight of said Coliseum in the raid version pits the players against three different bosses in rapid succession. On heroic mode, each boss even comes with a set time limit before the next arrives, even if the previous one is still standing. The Crusader's Coliseum was Blizzards answer to players asking for less trash mobs between bosses after Ulduar. No trashmobs at all. No instance either, just a big circular arena.
* ''VideoGame/PhantasyStarOnline'' has the quest "Towards the Future", which is a boss rush of Episode I with a few rooms of enemies in between each boss. It's also [[ComplacentGamingSyndrome the only thing anyone ever plays]].

[[folder:Party Game]]
* ''VideoGame/MarioParty'' has one in two games, both of which require story mode to be completed at least once to prevent spoilers:
** ''Mario Party DS'' has this as a "Boss Bash" Minigame, where you get to fight the bosses in order as a TimeTrial. You don't have to worry about restocking or having to fight the bosses on reduced health -- but you DO have to beat them all in a row or you'll fail the entire minigame.
** ''Mario Party 9'' allows the player to choose between fighting only minibosses, only main bosses or all of them. Since bosses can't kill characters (their attacks only reduce scores), the challenge is based on which of the 2-4 challengers deals the most damage in each battle. The character with the highest overall rank is declared victor.

[[folder:Platform Game]]
* In ''VideoGame/{{Athena}}'', before facing the FinalBoss, you have to defeat every previous boss in order, with short segments in between.
* ''VideoGame/IWannaBeTheGuy'' unlocks a boss rush mode when you complete it.
* ''Manga/MiracleGirls: Tomomi to Mikage no Miracle World Adventure'' has rematches with all the bosses at the end of the game, though all of them are still {{Mini Game}}s.
* ''VideoGame/{{Ristar}}'' has "Boss Rush" available through a code.
* ''Spanky's Quest'' repeats every previous BossBattle in the final tower.
* The last stage of the arcade game ''VideoGame/{{Strider}}'' intersperses the majority of the bosses and mid-bosses from throughout the game, some of them fought simultaneously, with the boss of Stage 1 ultimately carrying the player to the scene of the final battle.
** The {{UsefulNotes/NES}} version of the game has a Sub-BossRush in the final area of TheVeryDefinitelyFinalDungeon, with Hiryu facing off against the 4 {{Mini Boss}}es from previous stages, before taking on [[BigBad Matic]] and the final [[BrainwashedAndCrazy ZAIN computer]].
** Strider's SpiritualSuccessor, ''VideoGame/CannonDancer'', does it in the final stage. In order: the game's first two bosses, a MirrorBoss and the entire QuirkyMinibossSquad, who are now all fought at the same time.
* ''Franchise/SuperMarioBros'':
** ''VideoGame/SuperMarioGalaxy2'' has the Boss Blitz Galaxy as one of the last three galaxies, and in it you go through a boss rush of five bosses from the [[VideoGame/SuperMarioGalaxy original game]].
** The level Boss Blitz in ''VideoGame/SuperMario3DWorld'', located at the end of World Flower, is this. Every boss except Prince Bully (who's a MiniBoss) and both Bowser forms will challenge Mario and his friends here.
* Used in several ''Franchise/SonicTheHedgehog'' games:
** The Sonic/Tails version of Sky Sanctuary in ''VideoGame/Sonic3AndKnuckles'', which gave you versions of the Green Hill and Metropolis bosses from the [[VideoGame/SonicTheHedgehog first]] [[VideoGame/SonicTheHedgehog2 two]] games, before the level boss, Mecha Sonic. Interestingly, due to slight alterations of sprite proportions and JumpPhysics between the Sonic games, the difficulty of the two nostalgia bosses here is inverted from their original difficulty.
** The first ''VideoGame/SonicAdventure'' featured a boss rush for the regular six characters that you can access in Trial Mode after beating their stories. Amy and Big's "rushes" consist of only one boss since that's all they have, and Gamma's rush only has his first and last bosses since his other boss fights are actually part of levels. Also, none of the battles against other playable characters were included in the boss rushes.
** ''VideoGame/SonicAdventure2'' had an optional extra three {{Boss Rush}}es: a rush of all the boss battles in the Hero Story when that story is complete; a rush of all the boss battles in the Dark Story when that story is complete; and a rush of all the boss battles in the game when Last Story is complete. Beating each rush is worth one Emblem.
** The final level (X Zone) of ''[[VideoGame/SonicAdvanceTrilogy Sonic Advance]]'' is a miniature BossRush of classics -- specifically, the first bosses of ''Sonic 1'' and ''Sonic 2'', before the real final boss shows up.
** XX Zone, the final level of ''[[VideoGame/SonicAdvanceTrilogy Sonic Advance 2]]'' is a BossRush of all the prior bosses from the game, although they take half the hits to beat. After all that you reach the final boss. This is also [[GetBackHereBoss a literal example]] as all the bosses in the game are rushing away from you and you have to run to it.
** The GameMod ''VideoGame/RobotniksRevenge'' is essentially a Boss Rush (and BossGame) of all the bosses from ''VideoGame/SonicTheHedgehog'' and ''VideoGame/SonicTheHedgehog2''. There are two modes in this boss rush: "Time Attack", which gives you infinite lives and checkpoints and rings between the bosses, and "Survival" which gives you three lives and no checkpoints or rings.
** ''[[VideoGame/SonicTheHedgehog4 Sonic the Hedgehog 4: Episode I]]'' has the game's final zone, E.G.G. Station Zone. It consists of fighting the game's previous bosses before fighting the final boss.
** The [[NightmareSequence Nightmare Zone]] of ''VideoGame/SonicLostWorld'' has Sonic fighting all members of the Deadly Six together with various boss Nightmarens from the ''VideoGame/NiGHTSIntoDreams'' series.
** The final "regular" boss of ''VideoGame/SonicMania'' alternates between fighting Eggman and going through upgraded versions of the Hard Boiled Heavies.
* The NES version of ''VideoGame/{{Astyanax}}'' has a MiniBoss rush in its final stage before the confrontation with the BigBad.
* The entire ''Franchise/MegaMan'' series uses this, albeit not always executed the same way.
** A BossRush is typically placed in the second-to-last or last level in the game, although the initial game in the first two series dispersed the BossRush throughout the last few levels. It's somewhat bearable thanks to the ElementalRockPaperScissors weakness to each boss, meaning you'll likely own them in no time flat with little to no damage. Another bonus is the fact that the game typically gives you health powerups after each battle, so you fight each boss on more even terms. In fact, it's so ingrained into the ''Mega Man'' identity that they continue to do it even when, for most games, [[GrandfatherClause most gamers do not like the Boss Rush as part of the main game anymore]].
** ROMHack ''VideoGame/RockmanNoConstancy'' gave the boss rooms slippery floors.
** ''VideoGame/MegaManZero'' skews the boss rush out of focus, picking out the four strongest of the Neo Arcadian Reploids in the final stage for a rematch, then pulls a [[SubvertedTrope Subversion]] by having rematches with the [[QuirkyMinibossSquad Four Guardians]] themselves, who actually ''haven't'' been destroyed yet. Then the trope is [[DownplayedTrope downplayed]], when Hidden Phantom decides to pull a suicide attack. The return of the bosses is {{handwave}}d in retrospect -- being a technological Mecca, Neo Arcadia can rebuild their Mutos Reploid warriors with ease.
** ''VideoGame/MegaMan3'' had the Doc Robot, an enemy who copied the attack patterns of the bosses from the ''previous'' game.
** ''Zero 2'' throws the player for a loop by changing the attack patterns of one of the bosses in the boss rush entirely, by throwing in the brother you killed in the previous game. It's like they were feeling spiteful and wanted you to lose. Also, the return of these bosses is {{handwave}}d by the fact Elpizo used the power of the Dark Elf to bring them back -- though with heavy brainwashing in effect. One of those bosses also has an attack that invokes this, where he lifts Zero into the air and attacks him with phantom images of previous ''X''-series bosses ([[VideoGame/MegaManX1 Vile]], [[VideoGame/MegaManX2 Agile]], [[VideoGame/MegaManX3 Bit]], and [[VideoGame/MegaManX4 Colonel]]).
** ''Zero 3'' {{handwave}}s this, with the BigBad specializing in Reploid "revival". Even more stunning -- no less than ''four'' bosses return to fight you from the first game, all with brand new powers! If that wasn't enough for you, Copy X, the BigBad of the first title, is one of them! However, he's now stuck with a VerbalTic, and to prevent him from using his Seraph form and rebelling against Dr. Weil (and effectively becoming a case of final boss deja vu), Weil's rigged him with a self-destruct mechanism that goes off when he tries to transform.
** In ''Zero 4'', not only is there a regular BossRush, but the FinalBoss has an attack that is effectively a Boss ''Bum Rush''. He can summon the eight bosses from ''the previous game'' to quickly perform their signature attack before vanishing. Luckily, they don't have to be destroyed.
** ''VideoGame/MegaManBattleNetwork 2'', where Gospel attacks using images of three enemy Navis (Air Man, Quick Man, and Cut Man if you were curious) that the player fought ''just previously'' in the actual boss rush.
** And so does ''VideoGame/MegaManX8'', where the "revived" bosses are actually Reploids who have shapeshifted into them.
** And in ''VideoGame/MegaManZX'' and ''Advent'', the bosses are rebuilt in new bodies [[spoiler:thanks to the usage of [[ArtifactOfDoom Model W]]]].
*** ''ZX'', in addition to a normal mandatory BossRush, has optional rushes through eight select bosses of ''Zero 3'' and ''4'' (the first 4 fought in the final stage of ''3'', and the upper floor of boss teleporation chambers in the final stage of ''4''), in order to get the [[InfinityPlusOneSword Model O]][[note]]Omega[[/note]]. Instead of beating those 8 bosses[[note]]Or due to not having [=MMZ3&4=] games or playing the game on a [=DSi=] or 3DS, which lack the GBA cartridge port[[/note]], the player can opt to beating a single BonusBoss -- an ultra-pumped up version of Omega Zero (technically, residual data), which is HarderThanHard. Enjoy using up the subtanks.
*** Also in ''VideoGame/MegaManZX Advent'', there is a Boss Battles Mode, where you go through every boss of the game, without breaks in between. You are given all A-Trans and 2 full Subtanks, but you are not given any Heart Tanks or Biometal Upgrades. Good luck!
** This is [[UpToEleven upped]] in ''VideoGame/MegaMan10'' with the [[spoiler:Wily/[[SpellMyNameWithAnS Weapons]] Archive; essentially, you're up against three sets of three floating pods who imitate the attack patterns of nine Robot Masters, ''one from each of the previous games, including 7 and 8''.]] And ''then'' you have the classic BossRush expected from the game, later on.
** In ''[[VideoGame/MegaManV V]]'' for UsefulNotes/GameBoy there are two boss rushes: the first one is a sequential one with the Mega Man Killers and Quint, and the other one is a typical teleport one for the 8 Stardroids.
** ''VideoGame/MegaManUnlimited'', true to Mega Man tradition, has one of these in the fourth endgame stage. However, there is an added twist: [[spoiler: Before you fight each boss again, [[AllTheWorldsAreAStage you have to traverse a mini-stage based on the obstacles and enemies in that boss's original stage]].]]
** While Wily 3 is more of a {{Metroidvania}}, the Mechanical Arena unlocked in ''VideoGame/Rockman4MinusInfinity'' by beating the game is a straighter version (a homage to the Arena in ''VideoGame/KirbySuperStar''). It even has refills in the resting area and a method of travelling to the boss arena.
* ''Mega Man''[='=]s {{spiritual successor}}s follow the tradition:
** ''VideoGame/MightyNo9'' has one.
** Like in ''Mega Man Zero 3'', ''VideoGame/AzureStrikerGunvolt'', brings a justification in that one of the bosses is essentially a {{necromancer}} who can [[BackFromTheDead bring dead people back]]. [[spoiler:Said necromancer also has SplitPersonality, and while Gunvolt kills two originally, there's still a third...]]. The sequel's BossRush is instead explained with the BigBad having MagicMirror / MasterOfIllusion powers, resulting in the refought bosses being illusory copies of their original selves (this is hammered with their death animations: The original bosses die by going up in flames, while their copies turn into mirror reflections which then shatter).
* The ''VideoGame/{{Kirby}}'' series tends to feature an unlockable bonus BossRush mode.
** Several games (''VideoGame/KirbysAdventure'', ''VideoGame/KirbysDreamLand2'', ''VideoGame/KirbysDreamLand3'', ''VideoGame/Kirby64TheCrystalShards'', ''[[VideoGameRemake Kirby: Nightmare in Dream Land]]'', and ''VideoGame/KirbySqueakSquad'') simply pit you against all the game's bosses in order, with no chance for recovery. ''VideoGame/KirbyAndTheAmazingMirror'' randomizes the order of most of the bosses (the FinalBoss always being the last) and allows you a limited amount of healing items between rounds, similar to recurring game mode "The Arena"; ''Squeak Squad'' keeps the order of bosses the same, but provides a Maxim Tomato bubble at the start for Kirby to use if he's dangerously low on health.
** "The Arena" was first featured in ''VideoGame/KirbySuperStar'', where it pitted you against all the bosses from the various subgames in random order, ending with [[FinalBoss Marx]], and gave you healing items between rounds that you had to use wisely. Its remake, ''Kirby Super Star Ultra'', added ''two'' new variants on The Arena. The first is Helper to Hero, where you play as one of Kirby's numerous sidekicks through a shortened, pre-set order Boss Rush ending with new boss Wham Bam Jewel; and [[NintendoHard The "True" Arena]], where you fight the new bosses and minibosses added by the game's new subgames; the standard bosses and mini-bosses are in random order, but the arena ends with the "Final Four", consisting of Masked Dedede, Wham Bam Jewel again, Galacta Knight, and a TrueFinalBoss exclusive to the True Arena- Marx Soul. The healing items are also much less effective, making one of the [[NintendoHard most frustratingly difficult levels]] in the entire series.
** ''VideoGame/KirbysReturnToDreamLand'' continues the trend of having both a standard Arena and a True Arena: The Arena features bosses from the game's regular mode, while The True Arena features their powered-up forms from the extra mode and saves the five most powerful bosses for the end. One of those five is actually [[BonusBoss exclusive to The True Arena]], in the form of [[spoiler:Galacta Knight.]]
** The ''Kirby'' series has had a couple of mandatory Boss Rushes as well. In the first game, you had to fight the four bosses again before you could battle King Dedede. In ''Kirby's Dreamland 3'', ''VideoGame/KirbysAdventure,'' and several others, there's a level near (or at) the end where you face off with all the mini-bosses of the game again.
** ''VideoGame/KirbyMassAttack'' deserves mention for having two different Boss Rushes in a row and a more classic Boss Rush. The first is [[spoiler:Stage 4-9, in which you fight revived versions of Big Warwiggle, Great Gear, and King Eelongo. Beating them unlocks a new miniboss: Buzzy Bat, who is regarded by many as the hardest miniboss in the game. Immediately after beating them, you fight the Final Boss, Skullord. Beating him with all of the Rainbow Medals, however, unlocks the real final area... which is a Boss Rush for all four major bosses: Whispy Woods, Lady Ivy, King Dedede, and Skullord. Beating THEM unlocks the True Final Boss, Necrodeus himself. Oh, and you get a more complete Boss Rush of most of the minibosses and bosses by getting all of the Medals and talking to Daroach.]]
** ''VideoGame/KirbyTripleDeluxe'' also has The Arena and The True Arena, following similar rules to ''Return to Dream Land'''s. This time, however, the boss exclusive to The True Arena is a stronger version of the game's original final boss (Having been absent from the extra mode), with [[TrueFinalBoss an additional phase]]. Aside from the two arenas, ''VideoGame/KirbyTripleDeluxe'' has mandatory rematches against all five of the bosses in the final world, spread out across two levels. Their attack patterns are different from in the original battles to make them a bit more difficult. The last leg of the final level has a miniboss rush with a twist; you're in [[LimitBreak Hypernova]], and proceed to one-shot multiple DX versions of the minibosses, ending with a third rematch with the game's first boss, Flowery Woods, that Kirby [[CurbStompBattle swallows whole]] in seconds.
** ''VideoGame/KirbyPlanetRobobot'' mixes things up a bit by having you face the game's bosses in a fixed order rather than randomized, and gives you healing items periodically instead of from the start. Like ''Triple Deluxe'', its version of The True Arena also ends with a TrueFinalBoss battle against a stronger version of the original final boss, with an additional phase. The second boss of the game is also a small Boss Rush in itself, being a hologram projector [[HardLight creating]] four weaker versions of bosses and minibosses from previous games.
* ''VideoGame/NinjaGaiden II'' justifies this when you eventually go ToHellAndBack. Along the way, you meet all four of the major bosses that you've killed before, kill them in hell, fight the evil ninja who started the whole damn thing, save the girl, and THEN you get to the final boss.
* ''VideoGame/BlinxTheTimeSweeper''[='=]s last boss forces you to beat the 4th, 6th, 7th and 8th bosses in one run, and then proceeds to fight you itself.
* ''Franchise/{{Castlevania}}'':
** A bonus BossRush mode is a common unlockable feature in later games. Notably ''[[VideoGame/CastlevaniaHarmonyOfDissonance Harmony of Dissonance]]'', the ''[[VideoGame/CastlevaniaChroniclesOfSorrow Sorrow]]'' duology, ''[[VideoGame/CastlevaniaPortraitOfRuin Portrait of Ruin]]'' and ''[[VideoGame/CastlevaniaOrderOfEcclesia Order of Ecclesia.]]'' You battle all the bosses in a row, aiming for the quickest time, often to unlock special weapons and equipment for the main game. Quite often given a bit of extra replay value though allowing you to use the bonus characters from the game as well.
** ''Harmony Of Dissonance,'' while allowing you to play through the Boss Rush as Juste or Maxim, also lets you play as the original 8-bit Simon Belmont Sprite, with a remix of [[{{Leitmotif}} Vampire Killer]] for the music. He can't double jump or dash, but he is much tougher, dealing far more damage and having far more hit points.
** ''VideoGame/CastlevaniaBloodlines'' features at the start of its BossBonanza final level, a fight against [[TheDragon Death]]. While Death is normally a recurring staple of the franchise, before he's fought the player has to pick off cards that summon previous boss fights ([[DegradedBoss in reduced abilities]]) from the levels, in a [[ColorCodedForYourConvenience monochrome backdrop]].
* VideoGame/DevilSurvivor has a form of this in one of the MultipleEndings; the FinalBoss, ''before you can even touch him'', will summon '''''all''''' [[ThatOneBoss Bel bosses]]. Sure, some of them are ''much'' easier due to the difference in levels. Others... ''not so much''.
* Happens at the end of ''VideoGame/{{Rayman}}'', where the final "boss" is in fact three boss fusions fought back-to-back.
* ''[[VideoGame/JoeAndMac Joe & Mac 2: Lost in the Tropics]]'' had the player fight every single boss before the last boss.
* ''[[UpdatedRerelease New Play Control!]] Videogame/DonkeyKongJungleBeat'' features a level called "Kong of the Mountain", where you have to fight Dread Kong, Karate Kong, Ninja Kong, Sumo Kong, and Ghastly King without any chance of recovery (and with only 500 beats, to boot).
* ''VideoGame/{{Rosenkreuzstilette}}'', a doujin clone of ''Mega Man'', obviously has this.
* ''VideoGame/PrinnyCanIReallyBeTheHero'' has the second-to-last level, Sweet Palace, which pits you against souped-up versions of bosses you've fought in previous stages, interspersed with short platforming areas. What makes this example interesting is that, depending on which boss (or bosses) you battled in the six initial stages, some will change up during the rush. For example, if you chose the Demon Sea Casino Stage first, you battle Bok Choy, a Zombie who's extremely easy. In the aformentioned Sweet Palace, he decides to sic Cyberclops on you instead of rematching. If you already beat Cyberclops by choosing the stage fifth or last, it gets upgraded to 2.0 and has harder to avoid attacks. Likewise, if the High Tome Forest was picked first, you fight Kim, a Magic Knight. In Sweet Palace, she calls up her twin sister, Chi, to assist her in the fight. If Anise the Cat Witch was involved in any way (including the 3 on 1 midnight battle), she faces you alone.
* Level 19 of the SNES version of ''VideoGame/PrinceOfPersia1''.
* In ''VideoGame/ShovelKnight'', when you complete the Ascent stage of the Tower of Fate, you literally drop in on the bosses' dinner party, and they each attack you one by one. The order is different each time you face them. In the case ''Plague Of Shadows'', you literally drop in on the bosses' dinner party, but then [[spoiler: Shovel Knight]] drops in on you, and he ends up in the chair where Plague Knight would normally sit. The bosses attack you one by one, again with the order being different, but then you fight [[spoiler: Shovel Knight]] as the final opponent in the Boss Rush. The Boss Rush is removed from ''Specter of Torment''
* ''VideoGame/{{Something}}'': [[spoiler:The TrueFinalBoss. Also, [[DePower Mario has to do it without power ups]].]]
* The second-to-last stage of ''[[VideoGame/{{Bonk}} Bonk's Adventure]]'' involves fighting the bosses of the first four worlds all over again, the same as before. ''Bonk's Revenge'''s final stage is a HubLevel leading to four mini-levels each ending with one of the first four bosses. After clearing these, you fight the Round 6 boss and the FinalBoss in sequence.
* TheVeryDefinitelyFinalDungeon of ''VideoGame/WonderBoyInMonsterLand'', which is also TheMaze, has you fight each previously-encountered boss at a certain point. They're just as tough as before, but you're probably much stronger now. Of course, if you take the wrong path and get sent back, you have to fight them again. And there are no continues here. ''VideoGame/WonderBoyInMonsterWorld'' also has one in TheVeryDefinitelyFinalDungeon.
* This can be bought with targets in ''VideoGame/AssassinBlue'', after the game is completed.
* In the UsefulNotes/SegaGenesis version of ''VideoGame/{{Wardner}}'', towards the end of the final level, you fight all the bosses from the previous five levels again.
* In ''VideoGame/MetalStorm'', you fight all of the bosses you've met so far, then you fight the final boss.
* In the final level of ''VideoGame/StreetFighter2010'', you have to beat [[BossRush every previous boss]] and the final boss all within the same time limit. Not helped by [[TimeKeepsOnTicking the time limit still counting down through the cutscene before the final boss]].
* ''VideoGame/TheLegendOfDarkWitch''[='=]s final stage features a boss rush level similar in style to the ''Mega Man'' games, where you fight the bosses from all of the other stages (except the one from the Forest).

[[folder:Racing Game]]
* The Purple Gem Cup in ''VideoGame/CrashTeamRacing'' has you racing against all the non-final bosses in the game. At least they don't [[TheComputerIsACheatingBastard drop 1000 TNTs per lap]] anymore.
* The BigBad of ''[[VideoGame/NeedForSpeed Need For Speed Carbon]]'' hired the three last bosses where you have to at some point beat them, but individually. However, the final race requires you to defeat all three in a canyon race and a street race before taking on the BigBad, ''then'' you can take him on in a street race and canyon run. That puts the end at four consecutive races.

[[folder:Real-Time Strategy]]
* The Hole of Heroes in ''VideoGame/{{Pikmin}} 2'' is a Boss ''Dungeon'', with some regular floors, some rest floors, but mostly boss floors, pitting you against most of the game's previous bosses, and ending with a boss exclusive to the hole: the Raging Long Legs. Luckily, you DO get to save between levels.
* ''VideoGame/DynastyWarriors 6'' has this in [[ThatOneBoss/BeatEmUp Lu Bu's]] version of the Battle of Hu Lao Gate. Apparently the only remaining challenge for him was to have two dead bosses ([[spoiler:Zhang Jiao and Dong Zhuo]]) come back from the dead, the leaders of the Three Kingdoms unite, and for almost everyone else in the game to dog pile ya. If you beat them all, though, they all come back from the dead (in [[spoiler:Zhang Jiao and Dong Zhuo]]'s case, ''again'') in Hyper Mode.

[[folder:Rhythm Game]]
* ''VideoGame/ParappaTheRapper'' offers a bizarre example: You're [[PottyEmergency desparately standing in line for the bathroom]] with all the previous stages' bosses, and you have to out-rap them to get past them in line, otherwise you'll [[PottyFailure poop yourself]]. The sequel ''Parappa The Rapper 2'' does something similar to this, [[spoiler:in the form of a Food Court video game]] in a stage late in the game.
* In ''[[VideoGame/RockBand Rock Band 2]]'', the career mode features four setlists called "Guitar/Drum/Vocal/Bass Legend", in which you play the five hardest songs on each instrument in the game in order of difficulty.
* ''VideoGame/{{DJMAX}} Technika'' has the Conqueror Set, a Technical course whose stage 1-3 songs consist entirely of boss songs from previous courses.
* ''VideoGame/DanceCentral 2'' has a final stage composed of 5 dances, which are the final or boss-type dances of each dance crew.
* The Kaiden course in later ''VideoGame/{{Beatmania}} IIDX'' installments consists of the four hardest songs out of the entire series (three hardest on Doubles). The Single version of the course always ends with Mei, and the Double version always ends with Quasar.
* All VideoGame/DanceDanceRevolution games have this in some form. The Wii games have a medley of bosses from each previous game, but most other games just have you play them back-to-back.

* In ''VideoGame/TheBindingOfIsaac'':
** The Chest, [[TheVeryDefinitelyFinalDungeon the final level of the game]], every room contains at least one of the game's bosses, which leads up to the final boss: [[spoiler:??? (AKA Blue Baby)]]
** ''Rebirth'' introduces an optional challenge room that can be accessed if you defeat Mom in under 20 minutes. What lies inside this room is a massive gauntlet against ''thirty'' bosses, two at a time. Fortunately, hearts always drop for every two bosses that go down, and the arena itself is about four times the usual size of a boss fight area, giving the player a lot of room to maneuver. This is an example of a boss rush encountered relatively early in its game: Mom is the DiscOneFinalBoss, and with all chapters unlocked, there is a total of [[spoiler:at least four additional floors to get through]] after the rush opens.
** To a lesser extent, ''Rebirth'' also has [[spoiler:it's True Final Boss, Mega Satan. He spends half of his first form attacking and the other half hiding completely invincible, sending other bosses out at you.]]
** ''Afterbirth+'' drops all pretenses and introduces [[spoiler:The Void, which contains ''multiple'' Boss Rooms, only one of which contains the TrueFinalBoss Delirium. Said boss itself qualifies for this trope, as its main attack method is to simply transform into nearly any other boss encountered (yes, this includes the {{Disk One Final Boss}}es), shifting between bosses faster and faster as it gets lower on health. The other boss doors can also contain other "final"/major bosses, with the exceptions of Mom, Mega Satan, Hush, and Ultra Greed, likely due to their room conditions, the length of fighting the latter three, and Ultra Greed being exclusive to Greed Mode.]]

[[folder:Shoot 'Em Up]]
* ''VideoGame/BattleGaregga'''s fifth stage has you fight upgraded versions of the Stage 1 and 2 bosses, then throws out a huge plane, then culminates with [[ThatOneBoss Black Heart]].
* ''Chariot'', the ShootEmUp in the three-games-in-one ''VideoGame/ThreeWonders'', has the player facing off against all of the previous bosses in groups of 3 during the final stage.
* ''[[VideoGame/DonPachi DoDonPachi dai ou jou]]'' features a [[NintendoHard very cruel]] take on the Boss Rush in a mode called Death Label. You fight the bosses of the game at second-loop difficulty, and at the very end, you get something better than a PerfectRunFinalBoss: TWO of them! Also, if you pick Leinyan as your doll and use her laser bomb, the bomb ''heals'' the boss! The final stages of both ''dai ou jou'', and its sequel, ''[=DaiFukkatsu=]'', also features rematch against the many bosses of ''[=DoDonPachi=]''.
* The ''VideoGame/FantasyZone'' series always featured a boss rush immediately before the final boss. Said boss rush is made all the harder by the fact that you cannot go to the store to re-purchase useful items unless you die.
* ''VideoGame/{{Gradius}}'':
** Each subsequent game in the main series features a variation -- a rush of five or six bosses from the ''previous'' game. ''Salamander'' (the second game) featured three of the Big Cores from ''Gradius'', ''Gradius II'' (actually the third game) had up to four Salamander bosses. ''Gradiuses III, IV'' and ''V'' had all-new bosses mixed into the rush, but always included at least one boss from its immediate predecessor. ''V'' does it ''twice'', first in Stage 2, then in Stage 6. As for the GaidenGame, ''Gradius Gaiden'', its rush consisted entirely of completely new bosses, though two Deaths make up part of one of the bosses.
** The incredibly NintendoHard ''Salamander 2'' doesn't have a boss rush. Neither does ''Gradius Galaxies''; the first mid-boss of Stage 8 is less of a Boss Rush and more of a SequentialBoss.
* ''VideoGame/TheGuardianLegend'' had a special mode where you ran through all of the vertical-scrolling shooter stages in a row, skipping the mazes and key-collecting. There's also the boss rush while escaping, where you fight many previously-encountered bosses, then just when you think it's over, "It", a GiantSpaceFleaFromNowhere, shows up, apparently in a final act of revenge for the destruction of Naju.
* The last stage of ''Lightning Fighters'' includes rematches with the Stage 1, Stage 2, and Stage 6 bosses before the final two.
* ''VideoGame/{{rRootage}}'' is one big BossGame, consisting of four modes (normal, [[ShoutOut PSY]], [[VideoGame/{{Ikaruga}} IKA]], [[VideoGame/GigaWing GW]]), each one having 40 stages. Each stage consists of a five-boss Boss Rush, and the 40 stages consist of 30 stages of pre-defined bosses and 10 stages of randomly-generated bosses. 5 bosses * 30 pre-defined stages * 4 modes = '''600 bosses'''. Tally in the random stages and you have a near-unlimited number of bosses.
* ''VideoGame/StarSoldier'' on the PSP presents you with ''Boss On Parade'', a boss rush mode which is unlocked when you beat the game once.
* ''VideoGame/{{Touhou}}'' has one in the form of Phantasmagoria of Flower View's extra stage, in which you have to defeat every character in the game in succession. Additionally, the fans have composed a couple of amazing boss theme compilations, known as [[http://www.youtube.com/watch?v=ESA63E6SzgE Last Boss Rush]] and [[http://www.youtube.com/watch?v=vxJavbRAo-0 Extra Boss Rush,]] which covers the {{Leitmotif}} every FinalBoss and BonusBoss through the 12th game, respectively.
* ''VideoGame/{{Fraxy}}'' is a Boss Rush shmup where the bosses are ''user-created''.
* ''VideoGame/SpaceHarrier'''s eighteenth and final level (Absymbel) is solely a parade of six of the previous bosses, except that [[BossSubtitles now they get names]]; given the nature of the game, it actually turns out to be somewhat of a BreatherLevel.
* The final levels of both ''VideoGame/{{Rez}}'' and ''VideoGame/ChildOfEden'' do this.
* ''VideoGame/{{XOP}}'' and its sequel, ''XOP Black'', have boss rushes as bonus stages. The original's Extra Stage 2 also features fights against the various minibosses from the other levels, in a rare example of a Miniboss Rush.
* Towards the middle of ''VideoGame/{{Hellsinker}}'', the player is taken to a strange dimension and must fight through four or five difficult bosses (as well as a strange midboss that [[SurrealHorror looks like a giant bloody crystal but meows like a cat]]). Oddly, you have infinite lives for this level, and are therefore at no risk of GameOver'ing, but screwing up the boss sequence results in you losing pretty much all of your score.
* ''VideoGame/BlazingLazers'' has this in Area 9.
* ''G-VideoGame/{{Darius}}'' has an optional Boss Rush mode, where you can pick which bosses you want to fight, the order you fight them in, and so on and so forth. Given each boss comes in two seperate flavours and there's fifteen stages, you could fight up to thirty bosses back to back if you wanted.
* ''VideoGame/HeavyWeapon'' has "Boss Blitz" mode, where you have only ''one life'' to take down all 19 bosses. Considering that 11 of them can [[OneHitKill kill you instantly]] regardless of shielding, it's pretty understandable why it's NintendoHard.

[[folder:Simulation Game]]
* In ''VideoGame/AceCombatZeroTheBelkanWar'', there is a bonus stage, "The Gauntlet." In it, three different ace squadrons come after you, one after the other, without restoring either your [[CriticalExistenceFailure health]] or your [[BottomlessMagazines ammo]] (well, not automatically - there's a Return Line). [[spoiler:If you defeat the final squadron quickly enough, Mobius 1, TheFaceless PlayerCharacter from ''VideoGame/AceCombat04ShatteredSkies'', will come after you alone.]] And the special appearance is only available on Ace difficulty, the hardest difficulty. And [[spoiler: Mobius 1]] is ''just as hard as you'd expect''. Especially considering they made it NintendoHard by letting the AI have ImprobablePilotingSkills, and can [[MacrossMissileMassacre fire multiple missiles at once]]. ''[[BadassBack Backwards]]''.
* ''VideoGame/ActRaiser'' has an extremely sadistic Boss Rush at the end of the game. The bosses are extremely hard, but can made simple by using all of your magic on them. But facing them all in a row with no chances to heal or refill your Magic Meter in between makes this Boss Rush next to impossible. And all the bosses are ''sped up''.
* ''[[VideoGame/NavalOps Warship Gunner 2]]'' has a mode called Boss Rush you unlock once you beat the game. It is Exactly What It Says On The Tin. You fight the game's superweapons one at a time without being able to reload your weapons or repair your ship in between.

[[folder:Stealth-Based Game]]
* The ''VideoGame/MetalGearSolid'' series is another game with an unlockable Boss Rush. ''VideoGame/MetalGearRisingRevengeance'' has a one section where you fight clones of the bosses you've previously defeated right before fighting the de facto head of Desperado Inc.. Interestingly enough however, this happens [[spoiler: just a little over halfway through the game and not at the end, there are a few more chapters and bosses after this]].
* In ''VideoGame/{{Assassins Creed|I}}'', during the final confrontation with [[spoiler:Al-Mualim]], the Piece of Eden is used to create specters of each of Altair's previous assassination targets to throw him off.
* ''VideoGame/{{Tenchu}} 3: Wrath Of Heaven'' offers one as the final Co-Op mission, pitting two players against 5 teams of two bosses each.
** ''Tenchu: Fatal Shadows'' has it as the last unlockable option in its [[MultiMookMelee Red Blade mode]], which pits the player against all the game's bosses in quick succession.

[[folder:Strategy RPG]]
* ''VideoGame/FireEmblem'':
** The final chapter of ''[[VideoGame/FireEmblemElibe Fire Emblem 7]]'' contains soulless clones (with mostly maxed-out levels and statistics, as well as legendary weapons) of the most dangerous Black Fang members in the game, plus Marquess Laus, and sics them on you all at once. One of the few exceptions to the "never tougher than the originals" rule. However, lucky for you, these morphs have no luck, possibly due to their lack of a soul.
** ''[[VideoGame/FireEmblemJugdral Fire Emblem: Genealogy of the Holy War]]'':
*** BigBad Julius has 12 beefed-up {{Mooks}} defending the final castle, waiting to charge your army as soon as you get close. They've got names, insane stats, powerful weapons, some even have holy blood. Plus, before that, he sends out 3 frustrating Falcon Knights and right-hand lady Ishtar... just as Arion goes for your home base with a group of dragon knights! (Luckily, these can be taken care of by having Altenna talk to Arion. They'll become friendly [=NPCs=] after that.)
*** ''Thracia 776'''s final level has 6 of the aforementioned beefed-up Mooks, and this time, they're clones of other characters (namely, Leidrick, [[spoiler:Sara, Lifis, Galzus, Evayle, and Dagdar]]) and will take their forms if they are dead.
*** ''VideoGame/FireEmblemAwakening'' brings back the Deadlords, except here they have more or less a chapter to themselves (two actually, if you count the DLC which pits you against ''36'' of them). There's also an earlier chapter where you fight Cervantes, Excellus, and finally Walhart in succession.
* ''VideoGame/ShiningForce II'' has a bonus map after the game that allows you to fight all the bosses ''at once''. As a bonus ShoutOut, the map is shaped like [[SonicTheHedgehog Sonic]].
* ''VideoGame/SuperRobotWars'' is usually generous with only having one or two bosses per-level at the very worst, but sometimes they just get ''mean''.
** In ''VideoGame/SuperRobotWars3'', the second-to-last level can hypothetically involve taking on Scirroco, the BigBad from [[Anime/MobileSuitZetaGundam Zeta Gundam]], his girlfriend, EnfantTerrible Wendolo, and three-fourths of his QuirkyMinibossSquad. And all their subordinates, for a grand total of 35 units. And you take them on with half of that. Fun.
** The version of that fight in ''VideoGame/SuperRobotWarsOriginalGeneration 2'', was only slightly less difficult, making you only fight Axel and ''half'' the QuirkyMinibossSquad before facing Wendolo. Then the next stage threw you against both the [[VideoGame/SuperRobotWarsCompact2 Einst]] and [[VideoGame/SuperRobotWarsAdvance Shadow-Mirror]], and the Shadow-Mirror don't have the courtesy to wait until you're finished with the Einst.
** In ''VideoGame/SuperRobotWarsAlpha 3'', the battle against Muge Solbados from ''Anime/{{Dancougar}}'' is a boss rush. He first sends his three henchmen against the team (along with several mooks). Once they're killed, Muge himself appear ''and'' summons four killed boss characters, two of them from previous games.
** ''VideoGame/SuperRobotWarsK'' sets a case of this fairly EARLY in the game by having to face almost all the named ''Anime/OvermanKingGainer'' characters very early. Two missions also send them alongside some ''Anime/GunXSword'' bosses.
** The real battle in the final scenario of ''VideoGame/SuperRobotWarsCompact3'' begins as Alkaid gives it his all and raises the Shura Gods to use against the team. Shou can't believe that they have to take on all the defeated Shura Gods as well as Alkaid at once but Marvel tells him not to get weak and Quattro says that those are just fakes without the real owner piloting it but Alkaid says that the fake Shura Gods are imbued with his power so they're as strong as the ones the team once faced.
* The final chapter in both ''VideoGame/NamcoXCapcom'' and its sequel ''VideoGame/ProjectXZone'' involve fighting not only the BigBad, but also the villains from the many franchises of Namco and Capcom (and Sega in the latter game). For the sequel, however, not only must you fight [[FinalBoss Byakushin]], Saya, Sheath, as well as [[CoDragons Dokumezu and Dokugozu]], but you must also fight the villains of each series that have remained at large up until this point (with the exception of [[VideoGame/StreetFighterIV Juri Han]] and [[VideoGame/{{Darkstalkers}} Baby Bonnie Hood]]), which include [[VideoGame/MegaManX4 Sigma]], [[VideoGame/{{Darkstalkers}} Pyron]], [[VideoGame/SakuraWarsSoLongMyLove Ranmaru]], [[VideoGame/{{Xenoblade}} Metal Face]], and [[VideoGame/TheLegendOfValkyrie Kamuz]].
* The last few levels of ''VideoGame/FreedomForce'' have you trying to rescue a team member from a time controlling villain. In order to get to him, you have to fight through slices of time, each containing a previously defeated villain at the height of their power.

[[folder:Survival Horror]]
* Inverted in ''VideoGame/EternalDarkness''. The game is a series of chapters taking place in various times and locales, each with a different player character. During the final battle, the heroine from the framing story channels each of the dead [=PCs=] in turn so they can take one last crack at the BigBad.
* A variant of this appears in ''FiveNightsAtFreddys4'':
** In Night 6 and 20/20/20/20 Mode, you must survive the 4 main Nightmare Animatronics (Nightmare Freddy, Nightmare Chica, Nightmare Bonnie, and Nightmare Foxy) until 4 A.M. At 4 A.M., Fredbear takes their place, forcing you to square of with the most difficult foes in the series.
** This also applies to Night 8, with you having to face the main 4 until 4 A.M., then having to deal with what is essentially a harder version of Fredbear named Nightmare. It is much more difficult, as not only are the Main 4 cheap beyond all belief, but Nightmare is ''much'' more relentless than Fredbear. [[SeeminglyHopelessBossFight It's so difficult that it's almost unfair.]]
* ''VideoGame/DeadlyPremonition'' has the "Psychic Spot C" sidequest, in which you are forced to fight all three of the game's bosses in a row. Since the second boss has two forms and the third has three, it's six back-to-back fights. You are given a chance to sleep between bosses, but not to save or restock on items.

[[folder:Third-Person Shooter]]
* ''VideoGame/MassEffect3'':
** As part of the ''Citadel'' DLC, Creator/BioWare had to create boss-level hostile versions of all six player classes for the showdown with [[spoiler: Shepard's evil clone]]. For [[MirrorBoss obvious reasons]] the storyline only uses one of them, which would be something of a waste, so they added the 'Mirror Match' option to the [[GladiatorSubquest Armax Arena]] which sends three each of all of them at you over three rounds.
** Another Armax Arena example comes from completing the glitch hunt sidequest, which culminates in a multi-round fight involving Atlas mechs, Geth Primes, Banshees and even a ''Possessed Praetorian''.
* Beating the game unlocks this as a bonus challenge in ''VideoGame/KidIcarusUprising''.
* The final stage of ''VideoGame/SinAndPunishmentStarSuccessor'' has you fighting each member of the [[QuirkyMinibossSquad Nebulox]] before fighting [[FinalBoss Commander]] [[BigBad Deko]].
* The Salmon Run mode of ''VideoGame/{{Splatoon 2}}'' has this as a ''tutorial level''; its main purpose is to teach you how to fight the seven most common Boss Salmonid that appear in the mode, but if you think that's hostile, it's ''[[NintendoHard nothing]]'' compared to fighting several Boss Salmonid at once on top of the actual hordes.

[[folder:Western RPG]]
* The original ending to ''VideoGame/BaldursGateIIThroneOfBhaal'', the expansion for ''VideoGame/BaldursGateII'', was to feature all the bosses you previously fought... in one battle. This was nixed in the final version (which just had a lot of enemies) because of a deadline, but the semi-official mod ''Ascension'' put it back in. This battle is both much harder and much more satisfying than the vanilla ending. ''Ascension'' even goes so far as to have [[BigBad Melissan]] casually resurrect Irenicus and Bodhi, BigBad and [[TheDragon Dragon]] of the previous game, for you to warm up with. And if you have Sarevok in the party it's possible for ''him'' to turn on you too, meaning you get to face every storyline boss in the entire saga again. Oh and if Imoen's around she'll [[KickTheDog turn her into the slayer and force her to attack you]]. [[spoiler: Although in her case you just have to stay away until [[IKnowYouAreInThereSomewhereFight she snaps out of it]].]]
* ''VideoGame/IcewindDale 2'' has one of the enemies at the end summon the shadows of a few formerly fought bosses.
* ''VideoGame/JadeEmpire'' did this with the penultimate battle in the Gold Division of the Arena, where you fought all enemies you previously faced in one battle (there was a delay between the appearance of each, so you wouldn't be completely overwhelmed). This fight is optional (as is the entire Gold Division).
* ''VideoGame/{{Undertale}}'' has [[spoiler:the second phase of the TrueFinalBoss, Asriel Dreemurr. He has absorbed the souls of all your friends, and to rescue them, you have to engage them in battle, where they use the attacks they used in their previous boss fights (though Alphys uses Mettaton's attacks, as you never actually battle her, and Toriel and Asgore, as well as Papyrus and Sans, are fought together). Your goal, however, is not to defeat them, but bring them back to their senses.]]
* In the Gauldur Amulet questline in ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', you must defeat three unique powerful Draughr Deathlords to recover the pieces of the Amulet. When you take them to the one place they can be assembled, the spirits of the three return for one last crack at you. They obligingly take turns though they offer no breaks in between fights.
* Curiously inverted in ''VideoGame/FalloutNewVegas''; depending on the choices you make and how many side-quests you engage in, the final battle at the Hoover Dam is you and MAYBE a few of whichever major faction you're hanging out with (NCR or Legion) against [[ZergRush huge waves]] of the other major faction. The more side-quests you complete and allies you build up, the more rounds of back-up you receive, up to and including massive artillery strikes and bomber runs as well as a literal army of killer robots and tactical strike teams of Brotherhood of Steel Knights and [[spoiler: Enclave Remnants]]. Against guys in light armor with MAYBE rifles.
* ''VideoGame/PiratesOfTheCarribeanTheLegendOfJackSparrow'' Features one of these at the end. Upon completion of the tale, Jack and Will escape from the scaffolding just before they are hanged. The player regains control of them and they must fight their way to the docks through a ton of {{Mooks}} and expys of the games hardest bosses. You have three lives between the two of you and there are no rest stops, save points or healing items so good luck with that.

* All games in the ''VideoGame/AnotherCenturysEpisode'' series have Extra Mission 1 & 2, which are essentially boss rushes where you face ''two bosses at a time''.
* In ''VideoGame/IronTwilight'', if you spare the generator and also choose not to kill Felipe after defeating him in his dragon form, you're awarded with a new arc called the "Riot Arc". The plot changes significantly where Felipe tells the player that he wasn't the culprit, but a female vampire called Era Poi Riot was. Era Poi Riot comes about the area in which she summons shadow versions of [[spoiler:Felipe, Josephine, Death and Vulka]]. She summons the shadow again in the part where you have to fight her in person to make it an unfair match.
* The 3DS game based on ''Film/TeenageMutantNinjaTurtles2014'' has Shredder transforming into each of the game's bosses, in order, when his life meter is dropped to 0.
* The penultimate stage of the freeware game ''Blip & Blop: Balls of Steel'' is a boss rush against BigBad Dario and his fellow comrades, all of whom are original bosses that you haven't fought yet.
* In ''The Amazing VideoGame/SpiderManVsTheKingpin'' (Sega Genesis port for sure, unsure about the others), when Spidey reaches the bomb, he must fight every one of the villains he has faught thus far. He can disarm the bomb while being attacked, but it is a real pain in the ass to do so.
* The SNES ''WesternAnimation/{{Animaniacs}}'' game has you re-face four bosses before the final showdown with WesternAnimation/PinkyAndTheBrain. Okay, the King of Spades has been replaced with the Knight of Clubs, but the battle is basically identical.
* The ''[[LightNovel/MariaSamaGaMiteru Marimite]]'' doujin game ''Lillian Fourhand'' has its final level consisting of a rush with all of the mini-bosses and the first two bosses before you reach the final boss, a triple tag-team of the game's latter three bosses.
* The bonus mission "Arena" in ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R.: Perseus Mandate]]'' is a large arena-type area in which various enemies drop in to fight you. Between each wave of regular Replica soldiers a BossInMookClothing drops in to beat up on you; first a [[GiantMook Heavy Armor soldier]], then a PoweredArmor unit, then a riot shield Heavy Armor soldier [[GatlingGood with a minigun]], and finally a huge Leviathan mech walker that serves as the "final boss" of the level.
* The last set of levels in ''VideoGame/MarvelUltimateAlliance 2'' feature various rushes against the sub-bosses. [[spoiler:Nick Fury also uses the abilities of previous bosses, but in different ways]]
* ''VideoGame/ChromeHounds'' subverts this in the final mission. You think you're about to fight two of the previous bosses at once but when you kill one the level ends.
* In the ''VideoGame/MonsterInMyPocket'' NES game, you face the first five bosses in the final level and then get two units of health before fighting the main boss. [[NotQuiteDead Then you have to fight him again]].
* In the final battle of ''Iron Tank'', you fight the [[ThatOneBoss Think Tank Main Body]], followed by an F-type, then a C-type.
* The last stage of ''Hyperzone''.

* ''VideoGame/{{Solatorobo}}'' features two post-game [[VirtualTrainingSimulation "simulation"]] missions available on the Golden Roar, both of which pit you against every boss in either the first or second half of the game, ''back to back'', with no heals. The Type G's GradualRegeneration and the AutoRevive parts are fairly useful here.
* The final level of the ''VideoGame/Wolfenstein3D''-based game ''VideoGame/Corridor7'' ends in a series of small rooms, each one containing the previous bosses of the game, ending with the final boss.
* The last stage of ''VideoGame/{{Ghostbusters|1984}}'' for the UsefulNotes/SegaGenesis includes rematches with all of the previous bosses except Stay-Puft.
* ''Trigonometry Wars 4'' has Death Label mode, in which you fight eight bosses in a row: The first two are new, the next two are pulled from other games by the same creator, the fifth and sixth are the game's [[TrueFinalBoss]]es, and the final two are heavioly modified versions of bosses from Creator/{{Cave}} games.
* In ''VideoGame/SlySpy'', the climb up to the FinalBoss recapitulates every previous BossBattle that wasn't fought underwater or in a vehicle.
* In ''VideoGame/FeelTheMagic: XY/XX'', you're eventually forced a hallucinogen which makes you relive the three boss-level minigames as nightmares.
* Each mission (except the Premium Mission) in the first season's final chapter of ''VideoGame/MarvelAvengersAlliance'' has no goons and the boss is directly revealed. The boss is accompanied by other eight mini-bosses (which can be fought alone if you desire to ease the battle against him). The first mission features Thor's villains (being Loki the main boss), the second Hydra (being Baron Zemo the main boss), the third Hood's Gang and mystic villains (being Dormammu the main boss) and the fourth A.I.M. (being M.O.D.O.K. the main boss). And the fifth mission? Each boss of the other missions acting as mini-bosses to the Red Skull.

* The final battle of ''Videogame/HandOfFate'' is this - the Dealer will in turn summon the Jack, Queen, and King of each of the four suits, and when each wave is defeated, the player has the chance to attack the Dealer directly.

[[folder: Anime and Manga ]]

* ''LightNovel/{{Katanagatari}}'''s finale has Shichika defeating 12 warriors wielding the 12 katana he's been gathering with Togame during the entire series, but using upgraded tactics. [[spoiler:Since it's part of a RoaringRampageOfRevenge, he [[CurbStompBattle curbstomps]] them all, and it's awesome]].
* In ''Manga/{{Naruto}}'', the army that the BigBad brings with himself to the final battle includes [[spoiler: immortal undead made of most of the greatest badasses of the last three generations, including most of the series' deceased villains.]]
* In ''Manga/MedakaBox'', the 100 flowers run is an event where Medaka fights 100 previously defeated opponents. She's given a time limit of 90 minutes, too.
* In ''Anime/KillLaKill'', Ryuko spends episodes 8 through 11 fighting against the [[QuirkyMinibossSquad Elite Four]]. [[spoiler:Except she only fights and defeats three of them, because Nui interrupts the beginning of the showdown with the last remaining member, who she [[CurbStompBattle defeats]] [[OneHitKO with a single move]]. Nui ends up becoming Ryuko's fourth opponent and for Ryuko, things ''do not end well''.]]


[[folder: Literature ]]

* ''LightNovel/ACertainMagicalIndex'': After [[spoiler:siding with Othinus and making an enemy of the world]], Touma has to fight through a series of powerful opponents, most of whom he's already fought before. Notable in that [[spoiler:most of them actually let him win, or allow him to pass after he explains himself]].


[[folder: Live Action ]]

* ''Franchise/KamenRider'' occasionally has these. Especially in movies, where the villain of the movie calls in the help or resurrects the baddies of the series.
* Some final battles of the ''Franchise/PowerRangers'', though ConservationOfNinjutsu often applies. The final battles of ''Series/PowerRangersInSpace'', ''Series/PowerRangersWildForce'', ''Series/PowerRangersNinjaStorm'' and ''Series/PowerRangersJungleFury'' all end with one of these.
* Naturally, ''Franchise/SuperSentai'' also has these, as it is the source material for ''Power Rangers'':
** In an episode of ''Series/NinjaSentaiKakuranger'' has one of the baddies resurrect four previously defeated monsters, resulting in this trope.
** The final battle of ''Series/NinpuuSentaiHurricanger'' has the rangers fight manifestations of the previously defeated bad guys.


[[folder: Pinball ]]

* A variation appears in Stern Pinball's ''[[Pinball/TheAvengersStern The Avengers]]''; to complete the sub-WizardMode, "Assault on the Helicarrier", the player must make each Avengers' shot, in order, ''twice''.


[[folder: Tabletop Games ]]

* The ''TabletopGame/YuGiOh'' TCG has a card called "[[http://yugioh.wikia.com/wiki/Boss_Rush Boss Rush]]," part of a series of cards based on ''Gradius''. The effect is ExactlyWhatItSaysOnTheTin, in that the player may summon a "B.E.S." or "Big Core" card (these representing ''VideoGame/{{Gradius}}'' Bosses) at the end of each turn that a B.E.S./Big Core was destroyed. Since all these cards come into play with no counters, they're destroyed in battle (some cards can prevent this), but get a replacement at turn's end. If your opponent lacks Spell removal or monsters with over 2500 [=ATK=], this can cause them problems, at least for the twelve turns your stock of Bosses holds out, assuming you have a full stock. ''Boss Rush'' can be stacked for MoreDakka over a shorter time period.


[[folder: Web Original ]]

* ''WebAnimation/KingsOfPowerFourBillionPercent'': most of the animation consists of this, albeit with only boss fight per boss.
