->''"Going to some other dimension to fight a final battle is such a cliche!"''
-->-- '''[[VideoGame/NamcoXCapcom Xiaomu]]''', ''VideoGame/SuperRobotWars OG Saga: Endless Frontier''

You're off to fight the FinalBoss, so you end up having to go to another dimension. A VideoGame trope, probably caused because the developers want it to be memorable, impressive, and/or [[RuleOfCool awesome]]. May very well have an AmazingTechnicolorBattlefield or be a HighAltitudeBattle. It might also come with a SurrealThemeTune. The main thing, however, is that it's in its own dimension, universe, or whatever. Fighting the boss in a different time period also counts. May also be applied to {{Bonus Boss}}es, even though they're not the [[BigBad final boss]]. A common part of TrippyFinaleSyndrome, it is usually to be found in TheVeryDefinitelyFinalDungeon. Depending on the characteristics of the new dimension, it may or may not invoke InterestingSituationDuel. Sister trope to AmazingTechnicolorBattlefield.

A particularly common variant involves going ToHellAndBack, usually to defeat a baddie planning to unleash HellOnEarth.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* In ''Anime/TengenToppaGurrenLagann'', the final battle takes place in a pocket universe.
* Emperor Muge Zorbados, the DimensionLord BigBad of ''Anime/{{Dancougar}}'' is fought by the Dancougar team in his own pocket universe.
* In ''New Manga/GetterRobo'', the Oni Gods are faced in a universe made of Getter Energy.
* Anime/{{Beyblade}}: At the end of the first series, Takao and Yuri (get your minds out of the gutter) are warped into an otherworldly, frozen wasteland during their game. The outside just sees an enormous, spiked block of ice.
* Apocalymon, the final BigBad of ''Anime/DigimonAdventure'', was fought in a strange void that is neither in the Digital World nor the physical world. ''Anime/DigimonAdventure02'' had its final battle in the Digital World, but the first phase of the battle was fought in yet another plane of existence. ''Anime/DigimonFrontier'''s final battle took place literally in the void of space, and its climax happened in a wormhole tunneling between the real and digital worlds.
* The fight for Star Memory in ''Manga/RaveMaster'' takes place inside Star Memory.
* In ''Anime/DragonballZ'', the final battle against Kid Buu takes place on the Sacred Planet of the Kais in Other World.
* The fight with [[spoiler:the original Demon Lord]] in ''Manga/{{Superior}}'' takes place in a PocketDimension that may or may not be a physical representation of her mind.
* [[spoiler:Kirby's final battle with Nightmare at the end of the five-part series finale]] in ''Anime/KirbyRightBackAtYa'' [[spoiler:is divided into two parts, the first taking place on a gigantic chessboard floating amidst a red/blue oblivion where the pink spud tired himself out trying to physically attack the villain, and the second ACTUALLY taking place in the red spatial oblivion that is Kirby's dream, where he took control of the Star Rod and used it to overwhelm Nightmare. If it weren't for the fact that it was just that easy, this battle would've been epic.]]
* In ''Anime/YuGiOhCapsuleMonsters'', after Alexander opens the final door, everyone finds themselves in a new dimension where they must battle him for the fate of the world.
[[/folder]]

[[folder:Tabletop RPG]]
* Judges Guild adventure ''Dark Tower'' (1979), using ''TabletopGame/DungeonsAndDragons'' rules. The final battle against the BigBad Pnessutt the Lich took place in the highest level of the Outer Plane of Hades. The party had to activate a planar portal to reach him.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/AVeryLongRopeToTheTopOfTheSky'': In order to fight [[spoiler:Raccoon]], you have to enter [[spoiler:Ubiquity's]] computer system.
* ''VideoGame/BraveHeroYuusha'': In order to fight the Puppeteer, you have to take a portal to enter his Sky Fortress.
* Some Sonic games do this.
** Doomsday Zone from ''[[VideoGame/Sonic3AndKnuckles Sonic & Knuckles]]'' is set in outer space. While not technically another dimension, the battlefield and the battle itself are completely unique.
** ''VideoGame/SonicTheHedgehog2006'': Solaris is fought in a time and space fabric-deprived area, if that makes any sense.
** ''VideoGame/SonicGenerations'' plays this straight-up: the Time Eater is fought in some kind of trippy interdimensional passageway filled with clocks, and in the console/PC versions, fragments of the game's various levels.
* ''VideoGame/JetSetRadio'' possibly does this in the final "battle" against Goji Rokkaku. The game hints at this by adding glowing blue lights to the skybox and showing an odd death animation for Goji- who appears to fall ''upwards'' into the air after his defeat.
** However, the game's sequel, ''Jet Set Radio Future'' definitely uses this trope for its version of the battle against Gouji- it takes place on a strange, haphazard construction set without a visible floor and a ''very'' seizure-inducing background.
* The BonusBoss Culex in ''VideoGame/SuperMarioRPG: Legend of the Seven Stars'' is fought inside an alternate dimension that appears to be somewhere in the ''Franchise/FinalFantasy'' universe, probably near the ''VideoGame/FinalFantasyIV'' reality/world/whatever, judging by the [[SugarWiki/AwesomeMusic music]].
** The final dungeon and boss also reside in an alternate dimension: Smithy's home dimension, in fact.
* Some ''{{Franchise/Castlevania}}'' games take the protagonist into an alternate dimension to face off against the TrueFinalBoss:
** In ''VideoGame/CastlevaniaRondoOfBlood'' the background changes into a stormy portal when Dracula enters his second form, while the ''[[VideoGame/CastlevaniaTheDraculaXChronicles Dracula X Chronicles]]'' remake transports the player into a bloody alternate dimension for Dracula's ''third'' form.
** In ''VideoGame/CastlevaniaCircleOfTheMoon'', Nathan is transported into a FireAndBrimstoneHell during Dracula's second form.
** In ''VideoGame/CastlevaniaBloodlines'' Dracula's second form turns the throne room into a [[AmazingTechnicolorBattlefield trippy, seizure-inducing sine-wave backdrop]].
** In ''VideoGame/Castlevania64'' [[OverlyLongGag Dracula's third form]] transports the player from the castle top into a barren wasteland with a yellow sky and swirling clouds.
** While he doesn't have any second form in ''VideoGame/CastlevaniaSymphonyOfTheNight'', Dracula transports himself and Alucard into a strange pocket dimension deep within the [[TheVeryDefinitelyFinalDungeon Inverted Castle]].
** ''VideoGame/CastlevaniaAriaOfSorrow'''s final battle transports Soma into [[EldritchLocation the heart of Chaos]], the source of Dracula's dark powers, in his fight to seal the castle within the solar eclipse for good.
** ''VideoGame/CastlevaniaDawnOfSorrow'' presents us with Menace, fought inside a gruesome pocket dimension lined with [[BloodyBowelsOfHell thousands of bloody corpses]].
* ''VideoGame/SuperRobotWars OG Saga: VideoGame/EndlessFrontier'' has its final battle in the Einst dimension. It also has the final battle between the Namco characters Reiji and Xiaomu and their foe, Saya, which, while not the final boss of the game, counts because the game's dimension ''is'' an alternate dimension for them. Ironically, the page quote is for the latter, not the former.
** And the former is a CallBack to the final battle of its predecessor ''VideoGame/SuperRobotWarsOriginalGeneration 2'', which also takes place in the Einst dimension. [[spoiler:This is because the final area in OG Saga is the corpse of the final boss of ''Original Generation 2''.]] Of course, the TrueFinalBoss takes place [[HowDidWeGetBackHome back in normal space.]]
** In ''OG Gaiden'', after defeating Dark Brain, you're taken to another dimension to fight the TrueFinalBoss, which is... [[spoiler:Shu Shirakawa & his Neo Granzon]].
** The same happens in ''2nd Super Robot Wars Original Generation'' with the TrueFinalBoss [[spoiler: Euzeth Gozzo]]. The protagonists remark how similiar the space is, where they fought [[spoiler:Shu]].
* The final Specter fight in ''VideoGame/ApeEscape'' is fought in Dimension X, if the stage name in the NTSC version is to be trusted.
* ''VideoGame/TheLegendOfDragoon'' has one of the most fantastic examples of this throughout all {{RPG}}s, as the final battle takes place through the course of an entire world's creation, lifetime, and destruction. You go from AmazingTechnicolorBattlefield to the chaotic upheaval of a world being born, to new life [[TheWorldIsJustAwesome flourishing across it]]. You see the entirety of history come to pass through archaically-styled still images, ending with a prominent image of Death. And the grand finale of the fight takes place atop a ground composed of the corpses of everything that had lived on that world.
* ''VideoGame/SuperSmashBros Brawl: The Subspace Emissary'' has the final boss fight with Tabuu in the realm of Subspace.
** Any of the ''VideoGame/SuperSmashBros'' series, actually - the fight with Master Hand (or Crazy Hand) takes place in some sort of other-dimension (this is, of course, before Subspace Emissary came up).
* At the end of ''VideoGame/HalfLife1'', the game's SilentProtagonist is transported to the home dimension of the various alien creatures he's been fighting for the past day or so, Xen.
* In a heroic and [[JustifiedTrope justified]] twist, [[VisualNovel/FateStayNight Emiya Shirou]] ''weaponizes'' this trope in his final battle against Gilgamesh during the ''[[Anime/FateStayNightUnlimitedBladeWorks Unlimited Blade Works]]'' route by materializing his inner being into the real world as a barren, twilit pocket dimension filled with countless weapons. Cue dueling StormOfBlades.
* The ''Franchise/FinalFantasy'' series is fond of this trope.
** In the "Dawn of Souls" remake of ''VideoGame/FinalFantasyI'', once the party encounters Chaos, they are spontaneously whisked away into a psychedelic warp zone. In both the original and the remake, the entire final dungeon is [[spoiler:The Temple of Fiends/Chaos Shrine 2000 years in the past.]]
** ''VideoGame/FinalFantasyV'' does it by unleashing [[spoiler:the Void]], and [[spoiler:Neo Exdeath]] along with it.
** ''VideoGame/FinalFantasyVII'' goes from the core of the planet to a sky. Arguably an illusion, rather than another dimension, but the way the Lifestream works, it could be either. A BattleInTheCenterOfTheMind comes after this.
** ''VideoGame/FinalFantasyVIII'''s final battle against [[spoiler:Ultimecia]] starts out fairly normal, taking place in her throne room. Over time, the arena becomes more and more chaotic, until the party is whisked away into a dimension devoid of light and substance, the effect of Time Compression.
** ''VideoGame/FinalFantasyIX'' has the infamous fight against [[GiantSpaceFleaFromNowhere Necron]], which apparently takes place in [[spoiler:the afterlife]].
** In ''VideoGame/FinalFantasyX'', the final boss fight take place in a series of pocket dimensions within a giant flying whale monster.
** Inverted in ''VideoGame/FinalFantasyXIII''. The final dungeon is a bizarre pocket dimension full of enormous machines, patterns of pink lights and floating platforms, but you return to the real world for the BossBattle.
** The last few parts of ''VideoGame/FinalFantasyXIII2'''s amazingly long FinalBoss sequence are in [[PlaceBeyondTime Valhalla]].
** LightningReturnsFinalFantasyXIII has the final battle set in Cosmogenesis, a bizarre dimension home to the gods.
* ''VideoGame/DynamiteHeaddy'' has a battle on an AmazingTechnicolorBattlefield.
* A rather weird example occurs in ''VideoGame/{{Xenosaga}} Episode 1'', where the space station you're on inexplicably switches to a cloudy battlefield against the final boss.
* In ''VideoGame/KirbysReturnToDreamLand'' the final battle indeed takes place in another dimension. In fact it's the name of the final level!
* ''VideoGame/TheLegendOfZeldaMajorasMask''. The final boss battle takes place in an alternate dimension within an alternate dimension. Or something to that effect. Also, inverted in ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'', when, after going through the [[spoiler:second-to-]]last dungeon in an alternate dimension, during the boss battle Zant actually transports you to places in Hyrule visited previously during the game.
** The final battle in ''[[VideoGame/TheLegendOfZeldaSpiritTracks Spirit Tracks]]'' is another example. In order to track down Malladus and Cole, you need to use the Compass of Light to follow them into the Dark Realm, a dimension of evil that they fled to immediately after Malladus' resurrection.
** In the final battle in ''[[VideoGame/TheLegendOfZeldaSkywardSword Skyward Sword]]'', Link [[spoiler:enters a portal in The Sealed Grounds to the dimension where The Imprisoned was...well, imprisoned, to fight [[BiggerBad Demise]].]]
** Neither a final boss nor a bonus boss, nor a unique dimension, but Zaganaga in ''[[VideoGame/TheLegendOfZeldaALinkBetweenWorlds A Link Between Worlds]]'' deserves a mention: its dungeon is in Hyrule, but the boss itself is in Lorule.
* A couple quest bosses in ''VideoGame/{{Runescape}}'' have you follow them into their own dimension to fight them.
** End battle from Recipe For Disaster: the Culinaromancer, once you've gone and saved all the people he wanted to kill, you have to follow him and kill him and his tasty baked minions.
** The Spirit Beast from Summer's End is only defeatable by going into the Spirit Realm.
** In both Lunar Diplomacy and Dream Mentor you have to go to the Dream World to do the battles, though this is mostly for Dream Mentor as the battle Lunar Diplomacy is really very easy.
* The BonusBoss at the end of ''VideoGame/TheWorldEndsWithYou'' is one, in Another Day. This is a DoubleSubversion: Another Day is a relatively normal AlternateUniverse, but the fight takes place in Pork City, an [[AmazingTechnicolorBattlefield amazing monochrome battlefield]].
* In ''VideoGame/KingdomHeartsII'', Xemnas takes Sora and Riku into the Realm of Nothingness for the final battle.
** [[spoiler:Xion]] in ''VideoGame/KingdomHearts358DaysOver2''. You are transported to [[spoiler:[[{{Disney/AliceInWonderland}} Wonderland]], [[WesternAnimation/TheNightmareBeforeChristmas Halloween Town]], [[{{Disney/Aladdin}} Agrabah]], and back to Twilight Town again]] in the FinalBoss fight.
** In ''VideoGame/KingdomHearts3DDreamDropDistance'', [[spoiler: Ansem]] and [[spoiler: Young Xehanort]] are respectively fought in what appears to be the Realm of Darkness and in a strange dimension with clockwork gears in the background.
** Notably [[AvertedTrope averted]] in ''[[VideoGame/KingdomHeartsBirthBySleep Birth by Sleep]]''. [[spoiler: With the exception of Ven's final boss fight, none of the final bosses exhibit this trope. The TrueFinalBoss actually takes place in the previously visited town square of Radiant Garden!]]
* ''VideoGame/{{Bayonetta}}'' sets the stage by having you fight [[spoiler:the literal creator, Jubileus]]. New dimensions are created ''per phase'' of the battle.
* The final battle with Cyrus in ''[[VideoGame/{{Pokemondiamondandpearl}} Pokémon Platinum Version]]'' [[spoiler:and the subsequent battle against Giratina both take place in the Distortion World; Giratina even enters from the top of scene as opposed to the side once the battle starts, and it gets no floor tile underneath it]].
* ''VideoGame/GuruminAMonstrousAdventure'' sends you into the interdimensional portal that is "Great Fang" to face off against [[spoiler:Tokaron, the legendary dragon reawakened]].
* Arguably the premise of 'Rainbow Road' for many of the ''VideoGame/MarioKart'' series games.
* Given how the game's plot involves dimension hopping between levels, ''VideoGame/NuclearThrone'''s final boss[[spoiler: es]] are ''technically'' fought in a different dimension each time. [[spoiler: However, the most prominent ones are the Nuclear Throne's second form, which is accessed by meeting the conditions for a game loop and is fought within a giant dimensional portal, and the [[TrueFinalBoss Captain of the Interdimensional Police Department]] who can be fought in an alternate timeline where the nuclear apocalypse didn't occur.]]
* In order to fight [[EldritchAbomination Giygas]] in ''VideoGame/EarthBound'', you have to hop in the Phase Distorter and travel possibly thousands of years into Earth's past. Also, once released from the Devil Machine, it's suggested that he's so large and distorted that he ''is'' an EldritchLocation dimension in and of himself.
* ''VideoGame/WorldOfWarcraft'' has several:
** [[{{Uberwald}} Karazhan]] looks like a typical haunted tower filled with countless undead and AlienGeometries, but reaching the upper limits reveals that the player(s) have already passed from the normal world into what appears to be an extension of the Twisting Nether, as evidenced by the AlienSky that appears when fighting [[OurDemonsAreDifferent Prince Malchezaar]], the dungeon's final boss.
** The insane blue dragon Malygos is found in the Eye of Eternity, his private pocket dimension which is comprised of platforms floating in a starry void.
** Many of the Cavern of Time instances may or may not qualify due to [[TimeyWimeyBall the nature of the location]], but one stands out: the ''End Time'' heroic dungeon transports the player into a possible BadFuture for Azeroth, one in which the [[ApocalypseHow entire world]] is [[SceneryGorn utterly devastated]] and all its greatest heroes have fallen prey to the [[EldritchAbomination Old Gods]] thanks to Deathwing's victory, and in which the players must face and defeat Murozond, the Bronze Dragonflight leader turned evil.
** The Sha of Fear, the final boss of the initial 3 raids of ''Mists of Pandaria'', is normally fought in the Terrace of the Eternal Spring, where the light from the Terrace helps protect the players from the Sha's attacks, but in Heroic, he pulls the players into the Dread Wastes, a grey void in which the light wanes and the players must pass the light between themselves and keep it from being snuffed out by the Sha.
* In ''VideoGame/UltimaI'', you use a time machine to travel to the past and fight Mondain before he finishes creating the Gem of Immortality (which would make him unbeatable).
* The FinalBoss battle in ''VideoGame/{{Siren}}'' takes place in another dimension, and it fits this trope, but it's hardly an example of AmazingTechnicolorBattlefield.
** Its [=PS3=] remake, on the other hand is borderline seizure-inducing, with a bright, repeating kaleidoscope pattern.
* The FinalBoss of ''VideoGame/ChronoTrigger'', [[EldritchAbomination Lavos]], is fought inside his first form's shell. His final form, however, is fought as both he and the party are thrown across corridors of time, with various eras flashing by at high-speed.
** The final boss of the sequel, ''VideoGame/ChronoCross'', complements the concept by luring you into the darkness ''beyond'' time, where timelines discarded or destroyed by temporal paradoxes end up.
*** To put it in another way, ''VideoGame/ChronoCross''' final boss takes you outside of the boundaries of time, space, and dimension, and can be compared to where the title ship went in ''Film/EventHorizon''; you're nowhere at all, not even in the scope of alternate dimensions. It's an impossible-to-define area, because it isn't technically existent nor nonexistent. You're beyond the capacities of known concepts of reality, and not even in an alternate dimension so much as what could be compared to the necessary imaginary and impossible number in some types of advanced mathematics. Yeah.
* ''VideoGame/FreedomForce'', where the Timemaster rips the heroes out of the time continuum.
* ''VideoGame/WarioLand: Shake It!'' After you beat the boss' first form, he transports you to a battlefield in the clouds.
* Zig Zagged in ''VideoGame/SuperMonkeyBall Banana Splitz'', although there are no boss battles, the dreaded [[TheVeryDefinitelyFinalDungeon Master Stages]] take place in a time paradox.
* For some reason, the [[GiantSpaceFleaFromNowhere totally inexplicable]] final boss of ''Super VideoGame/AdventureIsland 2'' is some kind of one-eyed giant scorpion which you fight somewhere in space.
* ''VideoGame/LostPlanet'': While the rest of the game has you on the grounds of the planet, [[spoiler:the final level of the first game suddenly adds a new dimension (literally in a way, as this is the only time vertical movement isn't limited by fuel from your [[MiniMecha VS]]) as it takes place alongside a space elevator.]]
* In ''VideoGame/BaldursGate II'', you fight the final boss in hell. Which, yes, is another dimension.
** And in the expansion you have the final showdown in Bhaal's old divine realm, the titular ''Throne of Bhaal''. Which is also in hell, but looks very different from the one in the main game (gods can customize their divine realms, which Bhaal did [[spoiler: and Amelyssan does]]).
* The battle against Inferno in ''VideoGame/SoulcaliburII''.
** And Night Terror in 3. You fight inside Soul Edge itself.
* The TrueFinalBoss of ''VideoGame/{{Contra}}: Shattered Soldier'' is fought in a ''literal'' alien dimension accessed via the Relic of Moirai.
* Pretty much all of the ''Franchise/SilentHill'' games do this.
* ''VideoGame/{{Wild ARMs 2}}'' has the final battle and final dungeon take place in the area where an alternate universe has started to encroach on the current one -- the final boss ''is'' this alternate universe.
** Or rather, the boss that resolves the main plot. Shortly afterwards, you're [[GiantSpaceFleaFromNowhere abruptly thrust]] into a one-on-one fight with the ''real'' final boss, [[spoiler:which takes place either inside the protagonist's soul or on the edge of the Event Horizon. It's not entirely clear which, if not both.]] Bonus points for being taken out of one alternate universe to a seperate plane of existence.
* ''VideoGame/{{Wild ARMs 3}}'' does something similar to its predecessor. TheVeryDefinitelyFinalDungeon takes place in a different dimension, but after that there is a short period where you go back to the real world. Then, when you find the BigBad, they thrust you back into that different dimension for the boss fight. [[spoiler:She's not the true final boss, but immediately after the fight against her you get thrown into a fight with Nega Filgaia, which is.]]
* ''VideoGame/NeverwinterNights'' has you follow the final boss into a pocket dimension where her race has been hiding since the fall of their Empire. There's a bit of running round and slayage to do before you fight her, but only as a prelude...
* Happens in the final battle with [[BigBad Emperor]] [[AlwaysChaoticEvil Percival]] [[JerkWithAHeartOfJerk Tachyon]] in ''VideoGame/RatchetAndClankFutureToolsOfDestruction'' due to an errant blast from the Dimensionator.
** [[InvertedTrope Inverted]] in a sense in ''VideoGame/RatchetAndClankIntoTheNexus''; the final boss is coming from his dimension into yours, so it's still a "Final Boss, New Dimension"... for ''him'', at least. Played straight in the Clank segments during the fight, though, although those are the parts when you're taking a break from the boss to do some platforming.
* ''VideoGame/SweetHome'' never actually states what the final region where you fight Mamiya is, but it isn't the rest of the mansion.
* In ''VideoGame/TheLegendOfSpyro: A New Beginning'', the boss fight against Cynder takes place in a convergence of the planes.
* In ''VideoGame/{{Robopon}} 2'', the final battles take place in an unexplained, creepy location called the Robopon Graveyard. All you know is this is where the souls of Robopon go when they're scrapped, and the graveyard is totally filled.
* In ''VideoGame/{{Persona 2}}: Eternal Punishment'', the final dungeon is the Monado Mandala, part of the collective unconscious. In ''Persona 2: Innocent Sin'', the prequel, the final dungeon is Xibalba, a spaceship the Mayans built. [[spoiler:Which also turns out to have been a passage into the collective unconscious, which is hinted at then explicitly stated given the final boss room looks a lot like the "chamber" in a dream where Philemon greeted you near the beginning of the game.]]
** The ''Persona'' series likes this in general. The TrueFinalBoss of ''VideoGame/{{Persona}}'' is fought in the collective unconscious, too, while in ''VideoGame/{{Persona 3}}'' you [[spoiler:are drawn up to the full moon which has transformed into Nyx's body during the Dark Hour]]. ''VideoGame/{{Persona 4}}'' keeps its boss fights in the same alternate dimension half the game has taken place in all along, though... which is also arguably an aspect of the collective unconscious. This is a series where [[CarlJung Jung Was Right]], after all.
* The "Knights Of The Nine" quest line of ''VideoGame/TheElderScrollsIVOblivion'', has you fight the immortal BigBad's spirit in another plane of existence to destroy him for good.
* ''VideoGame/{{Ys}} III'' and ''V''.
* After you defeat Bowser for the third time in ''VideoGame/SuperMarioGalaxy2'', just as you're about to pick up the Grand Star, he pulls you into a black hole, and you fight him one more time here. If it weren't for the fact that this phase is [[AnticlimaxBoss laughably easy]], it would have been one of the best points of the game.
* For the first stage of the final battle of ''VideoGame/DevilMayCry'', Mundus transports himself and Dante into space.
* ''VideoGame/{{Bujingai}}'' has the final boss Rei creating a new space and planet (which he later bisects) in order to create a proper battlefield.
* The final boss of ''VideoGame/RadiantSilvergun'' is fought [[spoiler:in 100,000 BC]].
* ''VideoGame/{{Touhou}} 12'': ''Unidentified Fantastic Object'' has you fighting Byakuren in Hokkai, where she is sealed. Technically you got there in the previous stage, but close enough.
* Since ''[=SuperNOVA=]'', ''VideoGame/DanceDanceRevolution'' has had [[AmazingTechnicolorBattlefield Amazing Technicolor Dance Stages]]. X2 uses a special abstract pink colored stage for its TrueFinalBoss [[http://www.youtube.com/watch?v=bWH-ZYSL3Ds Valkyrie Dimension]]. And in fact, this is the first time this has been done.
* Astaros in ''Robo VideoGame/{{Aleste}}''.
* ''VideoGame/RType'' does this a lot: the final level of each game invariably takes place in the Bydo home dimension. ''R-Type Final'' also had a second alternate dimension made of TronLines, and one of the possible final levels taking place as your ship time-travels 400 years into the future to stop humanity from ever creating the Bydo in the first place.
* In ''VideoGame/SwordOfMana'', Julius transports the hero and heroine into an alternate dimension with him after beefing himself up on Mana power.
* ''VideoGame/{{Hellsinker}}'' does this in it's TrueFinalBoss, [[MindScrew we think]].
* ''VideoGame/{{Minecraft}}'''s final boss requires you to reach the dimension fittingly called "The End".
* The final boss in ''VideoGame/RuneFactoryFrontier'' is hidden in a seperate dimension called the Era of Disconnect so that it can't consume energy in the regular world.
* In ''Super VideoGame/FantasyZone'', the typical bright environment goes away after the BossRush, and the final battle is fought in the Shadow World.
* Magisphere in ''VideoGame/SaGaFrontier'' is a higher dimension designed explicitly for boss battles. In Red's game, many of the bosses are fought there (and it triples the power of [=BlackX=] enemies), while in Blue's game, Magisphere is reserved for the climactic duel between Blue and Rouge.
* In the doujin game ''VideoGame/CrescentPaleMist'', Narju Ar Larwin takes Yunou into an AmazingTechnicolorBattlefield [[spoiler:and she she's not the game's final boss]].
* In ''VideoGame/CthulhuSavesTheWorld'', the battle against [[spoiler: Azathoth]] takes place "Beyond Angled Space."
* For the final battle of ''VideoGame/PerfectDark Zero'', Zhang Li uses his newly acquired godlike powers to levitate the coliseum into the sky, where you fight him.
* ''VideoGame/CrashTwinsanity'' has the heroic crew use the Psychetron to enter the Tenth Dimension, where the Evil Twins are vulnerable at last. They're the final boss.
* In ''VideoGame/TheElderScrollsVSkyrim'', the final boss battle takes place in [[spoiler:the Nordic afterlife of Sovngarde]].
** The final battle against Miraak in ''Dragonborn'' takes place in [[spoiler:Hermaeus Mora's realm of Apocrypha. The final quest is even called "At the Summit of Apocrypha".]]
* The secret FinalBoss of ''VideoGame/StarFox1'' dwells in a stage called Out of This Dimension.
* In ''VideoGame/SaintsRowTheThird'', the final boss of the Save Shaundi ending takes place on Mars (except not really, it's actually a film set for an in-universe BMovie called "Gangstas in Space").
* ''[[Videogame/PanzerDragoon Panzer Dragoon Saga]]'''s final boss [[spoiler: Sestren]] is fought in a [[AmazingTechnicolorBattlefield psychedelic]] dimension [[spoiler: also called Sestren, that links together all the environment-controlling Towers in the world. It's implied that this dimension may actually be virtual, and Sestren a computer intelligence]].
* The NES version of ''VideoGame/DoubleDragon II'' does this for the TrueFinalBoss fight with the Mysterious Warrior.
** As a ShoutOut to the aforementioned ''Earthbound'' finale, ''VideoGame/DoubleDragonNeon'''s TrueFinalBoss battle warps you to a dimension "beyond space and time" where the Lee brothers are roboticized.
* ''VideoGame/AceCombat3Electrosphere''[='=]s final battle between the player and Dision (or an ill-explained rogue AI in the [[BadExportForYou plot-gutted export version]]) takes place in a not-very-attractive AmazingTechnicolourBattlefield. In the original version it's explained as the player and Dision cutting off visual and audio feed to the outside world and fighting each other in the eponymous Electrosphere; in the export version, it's apparently that rogue AI trying to hack your plane.
* ''VideoGame/{{Antichamber}}'': Once you catch the black block, you're transported to an endless void with floating platforms.
* In ''[[VideoGame/{{Darius}} G-Darius]]'', the "Genesis" stage suggests travelling back to ''before the Big Bang'' or something equally bizarre.
* In ''VideoGame/GrandiaII'', the final battle against Pope Innocent us takes place inside his mind, and even features a marathon against all the other Valmar parts you beat previously before you take him on in a two part battle.
* The final showdown with [[spoiler: [[BigBad Meden]] [[FinalBoss Traore]]]] in ''VideoGame/ProjectXZone''.
* Stages 15 to 18 of VideoGame/MonsterBag, including the final boss, take place on an alien world that the protagonists are warped to.
* In ''VideoGame/BravelyDefault'', the showdown with [[spoiler: [[BiggerBad Ouroboros]]]] takes place in the Infernal Realm.
* In ''[[VideoGame/FreeSpace Descent: Freespace]]'', the final battle against the Lucifer occurs in subspace.
* In ''VideoGame/{{Xenoblade}}'' [[spoiler: Zanza]] is fought in a dimension called "Memory Space", which is essentially a projection of our very own Solar System, created from the boss' memories from [[spoiler: before he became a god]]. The boss battle itself takes place in a location called "Sentient Genesis": a [[AmazingTechnicolorBattlefield constantly-changing]] void of space-time, and the seat of the boss' power and influence.
* In the third ''VideoGame/{{Splatterhouse}}'' game, the final battle sees protagonist Rick fighting against [[spoiler: [[BiggerBad The Terror Mask]]]] in some strange dimension consisting of a stone slab floating in a dark void. It's implied this is actually [[spoiler: Rick's mind]]
* Happens frequently in the ''Diablo'' series of video games.
** In ''VideoGame/DiabloII'', the final battle with Diablo takes place in the Burning Hells.
** Happens three different times in ''VideoGame/DiabloIII''. First, the player chases Diablo to the Heaven High Heavens to defeat him. Then, during the actual final battle, Diablo temporarily brings the player to the shadowy Realm of Terror for a portion of the fight. Finally, the ''Reaper of Souls'' expansion sees the player traveling to the dimension of Pandemonium to take on [[TheGrimReaper Angel of Death]] Malthiel.
* The true ending of ''VideoGame/HyperdimensionNeptuniaVictory'' have the protagonist group finally return back to their's original dimension to fight the final boss.
** [[UpdatedRerelease Re;Birth3]] adds a post-game event where the boss run away [[InsideAComputerSystem into a phone]], which prompts the CPU to use Nepgear's [[UsefulNotes/OculusRift Neptulus]] [[ChekhovsGun Rift]] to chase them inside the phone.
* At the end of ''VideoGame/TheFlintstonesTheRescueOfDinoAndHoppy'', Fred fights Dr. Butler in his home time period of the 30th Century, instead of Bedrock.
[[/folder]]

[[folder:Movies]]
* In ''Film/MortalKombat'', Liu Kang and Johnny Cage end up following Shang Tsung to Outworld for the final fight.
