** ''VideoGame/SonicMania'' and ''VideoGame/SonicForces'' both have final bosses take place in similar void dimensions created by the Phanotm Ruby.

* ''Franchise/MegaMan":

-->-- '''[[VideoGame/NamcoXCapcom Xiaomu]]''', ''VideoGame/SuperRobotWars OG Saga: Endless Frontier''

* The battle against Inferno in ''VideoGame/SoulcaliburII''.

* In ''Anime/DragonballZ'', the final battle against Kid Buu takes place on the Sacred Planet of the Kais in Other World.
* In ''Anime/DragonBallSuperBroly'', during the battle between Broly and [[spoiler:Gogeta]], the fighters eventually have a full on Beam-O-War, which results in the two seemingly breaking into another dimension. Eventually, the two clashed with a PunchParry so strong, it resulted in the two sending themselves back to the real world.

* In ''Manga/{{Naruto}}'', the final villain, Kaguya (not counting Sasuke) has the ability to travel to different dimensions. The final fight is fought through different dimensions, such as a volcano dimension, a frozen dimension, a sand dessert dimension and an extreme gravity dimension. The last part of the battle takes place in the central dimension, a dimension which Kaguya uses to access the other ones.

* You fight the second form of Wily Machine in ''VideoGame/MegaMan11'' in an AmazingTechnicolorBattlefield.

* In ''VideoGame/TheElderScrollsVSkyrim'', the final boss battle takes place in [[spoiler:the Nordic afterlife of Sovngarde]].

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.

* 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 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/EldenRing'' [[spoiler:after defeating the seemingly-final boss Radagon, the Elden Beast, the divine incarnation of Order, appears from his corpse and seemingly warps the player character and itself into a pocket dimension: a seemingly endless plane of walkable water, countless golden Erdtrees shining in the distance and a perennial golden sunset. Then, the true final battle begins.]]

* ''VideoGame/DevilMayCry1'': For the first stage of the final battle, Mundus transports himself and Dante into space.

* ''VideoGame/SweetHome'' never actually states what the final region where you fight Mamiya is, but it isn't the rest of the mansion.

%%ZCE* Astaros in ''Robo VideoGame/{{Aleste}}''.

** ''VideoGame/FinalFantasyIV'' features a final battle against TheManBehindTheMan Zeromus in a battlefield of rushing waves of stars, despite the party standing on a crystal platform moments before, and even a CutsceneBoss taken out in this way on the crystal platform itself. After the battle is over, the party promptly returns to the platform with no explanation as to what that sea of stars was.

** ''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/Persona4'' 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.

** Arguably the premise of 'Rainbow Road' for many of the ''VideoGame/MarioKart'' series games.

** ''VideoGame/TheLegendOfZeldaMajorasMask'': The final boss battle takes place in an alternate dimension within an alternate dimension. Or something to that effect.
** 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 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.

* 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.

* ZigZagged in ''Manga/FairyTail'', which divvies up the final battle against Acnologia between two locations: one is set in another dimension, the Space Between Time, where his disembodied spirit is locked in battle against the seven Dragon Slayers; the other half between the rest of the cast and his mindless body takes place in Hargeon, the humble PortTown [[WhereItAllBegan where the series began]].

* 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.

* The fight for Star Memory in ''Manga/RaveMaster'' takes place inside Star Memory.

* Kirby's final battle with Nightmare at the end of the five-part series finale in ''Anime/KirbyRightBackAtYa'' is divided into two parts. The first takes place on a gigantic chessboard, and the second takes place in Kirby's dream, where he takes control of the Star Rod and uses it to overwhelm Nightmare.

* In ''Manga/{{Naruto}}'', the final villain, Kaguya (not counting Sasuke) has the ability to travel to different dimensions(although it is implied that they are just planets outside the solar system, this is never confirmed and they are refered as dimensions). The final fight is fought through different dimensions, such as a volcano dimension, a frozen dimension, a sand dessert dimension and an extreme gravity dimension. The last part of the battle takes place in the central dimension, a dimension which Kaguya uses to access the other ones.

* ''VideoGame/BravelyDefault'' and ''VideoGame/BravelySecond'' do this with [[spoiler:Ouroboros]] and [[spoiler:Providence]] in the Infernal Realm and Celestial Realm respectively.

* ''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.

** 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.

* In ''VideoGame/XCOMApocalypse'', the grand finally of the Gollup based iteration of the series, the Aliens come not from another world, but AnotherDimension. Defeating them entails figuring out how to enter their dimension and wrecking all of their buildings, with the final mission focusing on destroying the building that lets them open gates to our world.

* ''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.

* In ''Manga/{{Naruto}}'', the final villain, Kaguya(not counting Sasuke) has the ability to travel to different dimensions(although it is implied that they are just planets outside the solar system, this is never confirmed and they are refered as dimensions). The final fight is fought through different dimensions, such as a volcano dimension, a frozen dimension, a sand dessert dimension and an extreme gravity dimension. The last part of the battle takes place in the central dimension, a dimension which Kaguya uses to access the other ones.

*** '''Shadowbringers''' has Emet-Selch take the battle that takes place during the destruction of his homeworld that [[spoiler: was shattered into 14 shards, one of them being the Source, the main world that players have played on for years, and the First, the shard that the expansion takes place in.]] He unleashes his true name of [[spoiler:Hades]] as the Warrior of Darkness and 7 others from across time and space come to fight against one of the strongest Ascians to date in the series.
