[[caption-width-right:242:It's the end of the world, and it's ''fabulous''. [[note]](from top to bottom: ''VideoGame/FinalFantasyI'' remake, ''VideoGame/RivieraThePromisedLand'', ''VideoGame/KirbySuperStar'', ''VideoGame/{{Mother 3}}'', ''VideoGame/SuperSmashBros Brawl'')[[/note]]]]

->''"GWAHAHA! Great dark hurricane! Seriously, perfect backdrop for an awesome final battle! You really sweat the details!"''
-->-- '''Bowser''', ''VideoGame/MarioAndLuigiBowsersInsideStory''

You've finally made it. You've beaten down countless FacelessGoons, cashed in your {{Plot Coupon}}s, trashed the QuirkyMinibossSquad and done away with the GoldfishPoopGang (and, if you have enough time on your hands, found the InfinityPlusOneSword). All that's left is the final showdown with the BigBad.

You're ready to take him on, but just before you can draw your sword, he snaps his fingers, and all of a sudden your party and the villain are transported to AnotherDimension. The villain's castle is gone, likely leaving you only with a floating platform on the edge of the void, or often standing on nothing at all, with various gyrating, pulsating patterns of colours and multi-colored nebulae providing the only background.

There may also be [[AsteroidThicket floating asteroids]] or ruins surrounding you, so that the villain can show how badass he is by making it look like he [[EarthShatteringKaboom destroyed the Earth itself]]. If the villain has ''actually'' succeeded in destroying most of the world, this would seem like the most logical place to fight, especially if the heroes have just completed TheVeryDefinitelyFinalDungeon.

Seen mostly in many recent fighting games and fantasy-themed {{RPG}}s.

Naturally, '''Spoilers ahead.'''


[[folder: Action Adventure Games ]]

* The final boss in ''VideoGame/BraveFencerMusashi'' has this.
* ''Franchise/TheLegendOfZelda'':
** The last battle in ''VideoGame/TheLegendOfZeldaMajorasMask''. At first Link is transported to a rather serene meadow, but then after talking to the lone boy by the tree wearing Majora's Mask, he suddenly ends up in an altered dimension with a vortex of colors.
** ''VideoGame/TheLegendOfZeldaTheMinishCap'' gives Vaati ''two'' {{Amazing Technicolor Battlefield}}s, the former resembling an acid trip and the latter a platform against a starscape.
*** He had it before that in ''[[VideoGame/TheLegendOfZeldaFourSwords Four Swords]]''.
** In a combined ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle]]'' game, one of [[spoiler:revived Ganon]]'s attacks turns the boss room into this for a few seconds. Oh, and [[InterfaceScrew reverses your controls.]]
** ''VideoGame/TheLegendOfZeldaSkywardSword'' has one for [[spoiler:Demise]], complete with the occasional lightning strike and FloatingWater.
** In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' has [[spoiler:the fight against Calamity Ganon take place in the huge, TronLines filled laboratory where he had originally been sealed]].
* The final battle with [[spoiler:King Boo]] at the end of ''VideoGame/LuigisMansionDarkMoon'' takes place in a purple-shaded vortex area.
* ''VideoGame/{{Solatorobo}}'''s final boss fight is [[spoiler:inside Tartarus]], which is full of floating squares in various shades of pink and purple.

[[folder: Action Games ]]
* In ''VideoGame/DevilMayCry'', before battling Mundus, he and Dante end up in space, [[strike: for some reason]] because Mundus ''[[RealityWarper creates]] a [[PhysicalGod universe]] for the two to fight in'', where you proceed to shoot fireballs at him.
** [[RuleOfCool Space with lots of lightning. You then fall into a pit of lava]] and [[SequentialBoss continue the battle.]]
** In ''3'', you fight [[spoiler:Arkham]] (who is, at the time, a black blob with purple streaks and four legs) in some kind of shallow pool of various shades of purple and pink with a lot of black spots thrown in (Said black spots being the eyes and mouths in the faces of the ''souls of the damned'' that make up said pool). And the exploding dolphin things he summons for you to fight to fill the time are also writhing in technicolour energy. Throw in your hero Dante's red [[BadassLongcoat coat]] [[spoiler:and Vergil's blue one]], and the only trippy colours you're missing are green and yellow.
* Subverted in ''VideoGame/{{Bomberman}} 64''. [[spoiler: Sirius activates the Omni Cube, and you basically fight on a floating grate inside a giant version of the cube, complete with a space-y background. Then after some fighting, Regulus shows up and attacks the cube (floating just out of reach the whole battle), bringing you back to Sirius' throne room.]]
* In ''VideoGame/OtogiMythOfDemons'', you fight the BigBad Michizane in a pocket universe where he has been burning/bathing his body in the light and flames of eight million stars, growing ever more powerful and becoming a PhysicalGod. And in the {{Sequel}} you fight the Nine-tailed Fox in the upper atmosphere of the planet, with snow and ice covered chunks of ground floating around.
* All the levels in ''VideoGame/CopyKitty'' are set on psychedelic backgrounds, especially if you set the graphics and effects on high. Justified, as the whole game takes place in {{Cyberspace}}.


[[folder: Beat Em Ups ]]
* Pick anything with a discotheque level. Anything.
* ''VideoGame/AsurasWrath'' has [[spoiler: The Event Horizon stage against the TrueFinalBoss, Chakravartin]].
* The final battle of ''VideoGame/CastleCrashers'' starts on a flying platform with a glowing red crystal encased in a wall of rock in the background, as the fight goes on, the wall of rock slowly gets destroyed until the platform you are on starts FALLING mid-battle. The boss himself gets pretty wacky as well.
* In the second D&D game Shadows of Mystara, you fight in one of these against an evil ghost-thing named Ezerholden. Depending on the path you take you might also fight a revived Deimos in a similar trippy temple setting.
* The final battle in ''VideoGame/ViolentStorm'' with the boss of the MonsterClown turns out to be against a small child who is a cross between Garlic of ''Anime/DragonBallZ'' and Tetsuo from ''Manga/{{Akira}}''. The castle lifts up into the air and into an alternate dimension as he becomes gigantic and malformed and bulky like Zarbon.

[[folder: Driving Games ]]

* Played in the ''VideoGame/MarioKart'' games, as well as ''VideoGame/FZero GX'', where the last raceway is a rainbow-colored hologram track high in the night sky. In ''Mario Kart'' this track is always called Rainbow Road; in ''F-Zero GX'', it's Phantom Road, though ''F-Zero X'' also featured a direct rip of the Rainbow Road from ''Mario Kart 64''.
* ''VideoGame/SonicR'', despite not having a boss, has something like this. The final level you unlock is a glowing racetrack apparently made of a rainbow or something.
** It's more likely it's a racetrack inside/made out of a/the Chaos Emerald/s, considering [[spoiler:Super Sonic's]] presence on the racetrack changes the music [[spoiler:and lets you beat the game for real]]. It doesn't happen on any other racetrack.
* The final race in ''VideoGame/SonicRiders: Zero Gravity'' takes place inside a black hole on a mobius strip track with a dark stormy psychedelic backdrop.
* Zone events in ''VideoGame/{{Wipeout}} HD'' and Zone Battles in the expansion ''Fury'' take place on a hologram of the track that starts out with all white surfaces and muted music. As the player gets to faster Zone categories, the music get louder and heavier, the track gets a progressively more intense color palette, and the track surface starts showing media-player-esque music visualizations. By the time you hit [[HarderThanHard Zen]], between the speed you're flying and the intensity of the presentation, you'll know exactly why the game comes with one of those unskippable seizure warning screens.


[[folder: Fighting Games]]

* The final boss battles in all of the games in the ''VideoGame/{{Soul|Series}}'' series.
** Prominent in ''Soul Edge''. The second to last battle: at a quiet port in Spain. The final battle: the same port (or chunks of it) drifting through trippy vortex-y space. The name of the BGM of this arena: "World Atlas Collapsed."
** The only exception to date is in ''Soulcalibur II'', where Inferno (the soul of the {{evil|Weapon}} [[ArtifactOfDoom sword]] [[TheCorruption Soul Edge]]) is fought in a stage called Tartaros. However, the trade-off is that you're fighting in the [[FireAndBrimstoneHell traditional depiction of]] ''[[FireAndBrimstoneHell Hell]]''.
* ''VideoGame/GuiltyGear XX'', the battle with I-No is fought in a black void with swirling red clouds and lightning strikes in the background. The screen will also FadeToBlack when she unleashes her Megalomania super special attack, one that [[SecretAIMoves you can't use]] when controlling her... unless you're playing ''Slash'' and beyond as EX I-No. The chances of a non-CPU opponent falling for it are slim, making it kind of a moot point.
* The fight against Master Hand in ''VideoGame/SuperSmashBros'' takes place on a single, flat platform before a swirling void. The fight with him in ''Melee'' starts in the same spot ("Final Destination") but then warps out of there, eventually flying over a sun-lit field. The in-game explanation is that as the fight goes on, it transfers to the "real" world.
** The prototype Final Destination (mentioned above) in the first ''SSB'' counts as well. You begin the fight in space/a starry-lit sky with tons of shooting stars in the background, which then shifts into what appears to be the inside of a purple nebula, and finally a blue vortex that becomes more and more unstable as you whittle down Master Hand's HP.
** ''Brawl'' has two Amazing Technicolor Battlefields: the Tabuu fight stage and the ''new'' Final Destination.
*** The stage the Tabuu fight takes place on could be considered a ContinuityNod (or perhaps InternalHomage) to the above-mentioned original Master Hand stage - the background is very similar, and the platform looks almost identical, only this time it's made of... [[PowerGlows glowy...]] [[PureEnergy energy...]] wing-shaped... [[BuffySpeak stuff.]]
*** Final Destination in ''Brawl'' definitely deserves further elaboration. The player starts in near-total darkness (the only prominent colors against the black are blue and green), treated to what appears to be ''the birth of a galaxy''. As the galaxy begins to pass the stage by, Final Destination travels through a wormhole and is ejected at a scenic view (presumably on Earth) featuring clouds, stars, and the sun. The visual fades and is replaced by a different swirling void with a bright light emerging in the middle. At the end of the tunnel, there is a breathtaking sunset landscape, set over a sea. Finally, the sea and sky start flipping around the main platform and the light eventually dims, bringing you right back to the beginning. The OminousLatinChanting and {{orchestral|Bombing}} [[AutobotsRockOut rock]] that score the stage's default BGM only makes the experience that much more surreal.
** Battlefield in ''Melee'' also counts.
*** Also to be considered is the battlefield in ''Brawl''[='s=] Great Maze in Adventure Mode, whenever you fight a cloned version of one of the fighters.
** True to form, the fourth game's imagining of Final Destination does not disappoint in this regard. The 3DS version more or less plays out like ''Brawl'''s, dropping the player in front of a galaxy. Then the player goes through a wormhole like in the previous games and ends in space, right before the earth itself. ''Then'' the glowing blue planet erupts, and when the light from the explosion clears, you're suddenly fighting over a sea--only this time, it's morning. Morning turns to evening, the stage moves into the sky/atmosphere, and finally travels through a second wormhole, placing you back a square one. The Wii U version is no less insane, with the sun and the earth in the background actually ''colliding into one another'', followed by a change in scenery to a morning sky.
*** In Classic Mode, [[TrueFinalBoss triggering the battle with]] [[spoiler:Master Core]] causes the entire background to briefly blacken before the area becomes a violently fluctuating swirl of various colors (predominantly yellow, orange, red, and black in the 3DS version), only periodically turning dark blue/indigo (complete with the galaxy seen at Final Destination's usual first section in the background) for a few seconds at a time. In ''for Wii U'', the colors alternate between what are mostly yellow and green hues and purple and blue ones, which actually makes it harder for [[spoiler:the Swarm that makes up Master Core's forms]] to stand out. Upon reaching [[spoiler:Master Core's true form]], the area becomes a blinding vortex of blue, unlike in ''for 3DS''.
* In ''VideoGame/DeadOrAlive 3'', you face off against Omega/Genra in a field surrounded by flames. Throughout the whole battle, the camera is shown at an over-the-shoulder angle, and the screen displays a perpetual motion blur.
* The final battles in ''VideoGame/TheKingOfFighters '97'' are pretty bizarre. The fights with Orochi Iori/Orochi Leona has the entire background turning red as a kind of symbolism for their current predicament ([[WithGreatPowerComesGreatInsanity The Riot of the Blood]]), and the battle with the Orochi Team takes place at an altar where the elements change constantly: first, it's covered in purple flames, then a lightning storm rages, and then it's surrounded by magma. When Orochi himself shows up, weirdly coloured shapes and patterns flash by in the background. None of this is explained in-game.
** In ''The King of Fighters '98: [[UpdatedRerelease Ultimate Match]]'', the stage select lists the latter two stages (which are apparently the same stage) as a "Different Dimension." The former examples are listed as "Bousou" ("Delusion") stages, which lends more credibility to symbolism. Magaki's stage in ''XI'', "The Different Space," is similar in some regards: The floor in the background is alit with blue flames and an odd sphere of light hovers in the middle of the stage. Luckily, that's about it. Bear in mind that Magaki travels via pocket dimension and it makes a little more sense.
** The final battle with Jivatma in ''Maximum Impact 2'' takes place on a marble floor, surrounded by a starry field. As it only appears after Jivatma snaps his fingers, this is probably an illusion.
** Orochi, Mukai, and Magaki can all ''create'' Amazing Technicolor Battlefields with their Desperation Moves (Orochi and Magaki use rays of light and Magaki's attack in particular resembles [[WatchItStoned an acid trip]]; Mukai attacks with pertrification waves of white and grey energy to achieve a similar effect). Igniz's HSDM/MAX 2 in ''2002: [[UpdatedRerelease Unlimited Match]]'' encases you in a galaxy, which he then ''detonates''.
* The final fight with [[spoiler:Hyo]] in the first ''VideoGame/RivalSchools'' takes place in a multicolor light-show stage called "Illusional Space", created by his hypnotism powers according to the story.
* ''VideoGame/StarGladiator'''s TrueFinalBoss fight against [[spoiler:Ghost]] Bilstein takes place from within a strange multicolored spinning tunnel-like vortex dimension that has shape-changing pulsating lights and images flowing from within the background while the fighters battle from upon a circle-esque ring that has a pulsating blue-purple aura image. Unlike the previous fights, the loser of the match gets sent hurling into a purple Plasma void.
* ''VideoGame/JoJosBizarreAdventureAllStarBattle'': If Enrico Pucci can evolve his Stand to Made In Heaven, it will change the stage to an interstellar platform leading to the new universe. As an added bonus, his opponent's movements will be slowed to a crawl while his own speed gains a boost.
* In ''VideoGame/PsychicForce 2012'', Emilio's last fight from within Story Mode is against [[spoiler:[[SuperpoweredEvilSide his evil side]]]] and that the battle takes place [[spoiler:[[BattleInTheCenterOfTheMind from within his own mind]]]], in which the battlefield itself has a lot of creepy red, blue, and purple pulsating shapes and patterns flashing from within the dark background, which is to possibly indicate Emilio's own [[spoiler:internal struggle]] against his [[spoiler:psychotic side]]. It's heavily implied from within his own ending that [[spoiler:Emilio loses this fight and is now [[FateWorseThanDeath trapped from within his own mind]] while his psychotic side is allowed to be free and continue his AxCrazy rampage]].
* Happens in the first ''VideoGame/SamuraiShodown'' game, when, after winning one round against Amakusa, he does soemthing that makes the whole stage look destroyed and covered in multicolor flames, and the huge stone in the background opens to reveal a glowing, winged demon. The music also changes greatly and his AI gets somewhat improved. Curiously, after you win, the stage goes back to normal. Another example would be the final battle of ''VideoGame/SamuraiShodown 2'', which takes place ''in hell'' and, accordingly, the stage is filled with bizarre visuals.
* Emerl's multiplayer arena from ''VideoGame/SonicBattle'' pretty much fits; it's a plain black background, and the entire foreground (i.e. the stage itself) is made up of a holographic-neon framework.
* The stage "The Portal" in ''VideoGame/MortalKombat2'' has the combatants (sorry, kombatants) fighting on a stony ledge in front of a swirling red void.
* ''[[VisualNovel/UminekoWhenTheyCry Ougon Musoukyoku]]''. The stages themselves are pretty amazing, but then someone invokes the Meta-World... [[http://www.giantbomb.com/ougon-musou-kyoku/61-36051/stages/52-562963/ Just have a look.]]
* ''[[VideoGame/GundamVsSeries Gundam Extreme Vs.]]'' has Extreme Universe (which becomes Extreme Evolution and [[NamesToRunAwayFromReallyFast Extreme Fatality]] in the sequels ''Full Boost'' and ''Maxi Boost''), where the background is a nebula-like swirl of glowing colors. On top of this, the floor is made up of a number of large hexagonal pillars, and the FinalBoss has the ability to raise and lower them (usually doing tricks like splitting the battlefield in half or creating pits) and his attacks have the power to temporarily destroy them.
* Various ''[[Franchise/BlazBlue BlazBlue]]'' stages can fall under this, such as "Sealed Space", "Sight of Gods", and "BLUE".


[[folder: First Person Shooter]]
* ''VideoGame/Halo5Guardians'' has its Rift Ball map, which is low-G Grifball in a neon-lit spaceship interior with floating crates for cover and plasma grenades to throw.
* Videogame/TeamFortress2: Activating Pyrovision changes the textures to a psychedelic effect (though the skybox color remains the same).
** Several fanmade maps, such as KOTH_Always (a map fashioned after ''VideoGame/RobotUnicornAttack'') are also like this.

[[folder: Game Mods]]
* Pretty much the entire 7th level of ''Donner Party'' (the ''Badderhacks.net'' ROM hack of ''VideoGame/MonsterParty''). Justified, since it takes place inside Ke$ha's rectal cavity, and we all know how much she likes glitter...

[[folder: Light Gun Games ]]

* Any fight against any of Anubis' incarnations in ''VideoGame/BattleClash'' or ''Metal Combat''.
* Interestingly, it's the BOSS of one of the ''VideoGame/TimeCrisis'' games that invokes this himself and not the stage. He's in a suit made of mini-TV things that render him invisible. When not in use it looks like he's wearing a suit made from no-signal-received analog TV screens

[[folder: MMORPGs ]]
* ''VideoGame/WorldOfWarcraft'' has a couple of these. The battle against Malygos, the Dragon Aspect of Magic, takes place in the Eye of Eternity, on a big floating rock platform surrounded by stars. During the fight, Malygos uses his breath to destroy the platform, which coincides with the entire background going into brilliant swirly colors. There is a bug where the colors occasionally don't go away once the final combat phase starts, causing severe problems for sensitive players. And Malygos isn't even the FinalBoss of the game.
** The BonusBoss, Algalon the [[strike:Observer]] Raid Destroyer, in Ulduar, is initially encountered in an observatory which turns into a starry outer space background once the fight is engaged. It makes sense, since Algalon is sent by the Titans themselves and looks like a humanoid constellation.
** Outland in its entirety could arguably be considered this, as the shattered planet floats through the psychedelic colors of the Twisted Nether.
** The For TheHorde! achievement has the fight against Prophet Velen inside the Exodar- which is already one of these (Well, for TheHorde anyway- it's a city to the Alliance), but Velen's suped-up priest abilities set off so many particle effects, it goes UpToEleven.
** The Lich King battle in Icecrown Citadel probably also counts. When your soul gets sucked into Frostmourne, it looks like [[http://static.mmo-champion.com/mmoc/images/news/2009/october/frostmourne2.jpg this]], with huge spectral chains swirling through the air.
** Ner'zhul in the Shadowmoon Burial Grounds is a traditional example - upon entering his room, he transports the party into a swirling void on a floating platform, where the fight takes place.
* The third form of Dark Falz in ''VideoGame/PhantasyStarOnline'' levitates you on a ring full of colourful glyph symbols high up in the air with the ground viewable below. Not only the stage, but the boss counts as well, with garish technicolour wings and a blazing bright sword-arm.


[[folder: Platform Games ]]

* The final battle against Dracula (and in a lot of cases Death as well), in a number of ''Franchise/{{Castlevania}}'' games, most notably ''VideoGame/CastlevaniaSymphonyOfTheNight'' and ''VideoGame/CastlevaniaCurseOfDarkness'' takes place in a dimension that resembles a swirling vortex of colors.
* ''VideoGame/MegaMan2's'' final boss is an alien thing against a black starry background... [[spoiler:but it's all smoke and mirrors.]]
* The final stages of ''VideoGame/MegaManX5'' are set in "Zero Space", a trippy-as-all-get-out area where the Zero Virus's overwhelming power has caused the real world and {{cyberspace}} to merge together.
* Each final boss in ''VideoGame/MegaManBattleNetwork'' does this. We go from orange streaks in the first game to the background dissolving, being absorbed by a giant amoeba, swirly cosmic stars and planets, peoples' souls gathering, and finally trippy, psychedelic tye-dye designs in the final game. As a matter of fact, the vast majority of battles in this series have a bright, abstract background.
* The last boss fight of ''VideoGame/RatchetAndClankFutureToolsOfDestruction'' against Emperor Tachyon takes place in an asteroid field on top of a relatively great asteroid. This is after the initial part of the fight is over though.
* In ''VideoGame/DynamiteHeaddy'', when Headdy finally reaches [[BigBad Dark Demon]], he [[FightWoosh whisks the throne room away]], transporting himself and Headdy to an area with nothing in it but zooming psychedelically-colored clouds, stars (or something), and invisible ground. This reverts to the throne room when he is defeated.
* Most ''VideoGame/{{Kirby}}'' final bosses have this.
** In ''VideoGame/KirbySuperStar'', you fight Marx (who went OneWingedAngel right after his plan is revealed) in an area that consists of a purple ground with stars on it constantly moving (yet you're not affected by it), with small suns peeking out from the distance, all with a space background behind it. It even glows red and green when Marx's health is two-thirds depleted in the VideoGameRemake. However, this was one-uped on by the battlefield of said remake's exclusive boss [[spoiler:Marx Soul]], which is more drug trip induced.
** In ''VideoGame/KirbysAdventure'', you fight Nightmare in the moon, which is a high speed, shiny blue version of the above example.
** The final boss of ''VideoGame/KirbysDreamLand3'' takes place in the Hyper Zone, an area consisting of a blue background with black clouds floating everywhere at a high speed (though in the BossRush, it is shown [[ThisIsYourPremiseOnDrugs with high-contrast bright colors]]).
** In ''VideoGame/Kirby64TheCrystalShards'', the place where you fight 02 is a red void with '''barcodes'''.
** The final battle of ''VideoGame/KirbysReturnToDreamLand'' takes place in an extremely colorful alternate dimension, with a floor that looks be made of stars and Popstar being visible through a portal in the background.
** While the initial phases of the final battle in ''VideoGame/KirbyPlanetRobobot'' are simply an AstralFinale, the final phase takes place in a kaleidoscopic interdimensional tunnel.
* In ''VideoGame/TheLegendOfSpyro: A New Beginning'', the game finale took place in an area known as Convexity, which pretty much fit this trope, complete with floating rocks and strange jellyfish-like creatures roaming everywhere. [[http://uk.youtube.com/watch?v=E1Ux39J5JUg See here.]]
* The final level of ''[[VideoGame/JetSetRadio Jet Set Radio Future]]'' is an odd jumble of a structure in a totally trippy world, away from the Tokyo setting of the rest of the game.
* Non-boss fight example: ''VideoGame/SonicHeroes'', the [[BigBoosHaunt haunted mansion level]] eventually turns into this after you hit a certain switch, with a few platforms floating in the midst of chaos. Once you hit another button... [[spoiler:The level becomes the outside of a completely normal mansion, and the goal appears.]]
* Nonaggression from ''[[VideoGame/SonicAdvanceTrilogy Sonic Advance 3]]''.
* Exception from ''VideoGame/SonicRush''.
* A third Sonic the Hedgehog example: at the end of ''VideoGame/SonicTheHedgehog2006'', the last level and last boss take place in a swirling, mystical void. Somewhat justified in that the boss actually ''has'' bitten a huge chunk out of the fabric of reality, and is simply letting that appetiser settle as he prepares to chow down on ''time itself''. Appropriately enough, the area is called "The End Of The World".
* Yet another Sonic example: the final boss of ''VideoGame/SonicGenerations'' is fought in a violet time void.
* Every Beastector battle in ''VideoGame/MischiefMakers'' is like this, as well as the battle with Monolith.
* The FinalBoss of ''VideoGame/DonkeyKongCountryReturns''.
* The final battle against Bowser in ''VideoGame/SuperMario64'' is on a similar platform to the previous two fights, but has some funky lighting effects thrown in that qualify it as this.
* The final boss battle in ''VideoGame/SuperMarioGalaxy2'' has [[spoiler:a giant black hole in the background, creating [[SuckingInLines black and white swirls]] and an ominous hum]].
* In ''VideoGame/Rayman3HoodlumHavoc'', during the final battle with Reflux, the battleground slowly degenerates from being the top of a stone tower, to floating shards of building with a swirly purple void in the background, to an arena bordered by giant space-plants with eyes.
* The arena of [[spoiler: [[OneWingedAngel Giga-Snail]]]] in ''VideoGame/{{Snailiad}}'' is very colorful.
* The [[EldritchAbomination Negativitron]] of ''[[VideoGame/LittleBigPlanet Little Big Planet 2]]'' has a vortex background in his third phase. Said vortex [[JustifiedTrope came from the arcade machine on the background]].
* Michael Sepperin in ''VideoGame/{{Rosenkreuzstilette}}'' has a strange area taking place in a cloudy oblivion for his second phase. [[spoiler:And later, you eventually fight his biological daughter and murderer amidst a yellow cloudy sky complete with clouds colored different shades of yellow and glowing white feathers floating upwards, and even the eventual appearance of a bright white sun, as if it resembled Heaven itself, and it's absolutely beautiful. During the final phase, the background fades to black when she's using her reflect laser attack.]]
** Likewise, the background for the final battle of ''Rosenkreuzstilette Freudenstachel'' [[spoiler:also takes place in a yellow sky with the same features as in the first game. The background transitions to a black oblivion with different shades of blue when Iris is using either her homing energy ball attack or her screen-filling Blitzstrahl attack, just before transitioning back to the yellow sky it was before]].
* The final boss battle of ''VideoGame/AHatInTime'' takes place in [[spoiler:the very fabric of time, after a DrunkWithPower Mustache Girl gets fed up with the villains cheering Hat Kid on]].

[[folder: Puzzle Games]]
* The final level in ''VideoGame/MightyFlipChamps'' takes place in what appears to be outer space. The background scrolls quickly.
* ''VideoGame/NightSky'' features a bonus world called [[spoiler: Slightly Nonsense]] that is not mentioned until you beat the game. Once you complete the requirements to unlock it, you find yourself going through levels with bright checkerboard terrain and unnatural suns, Photoshop-filtered photos in the background, and even a level that's entirely composed of [[spoiler: ASCII art]]! The puzzles here are more quirky (and difficult) than the rest of the game.

[[folder: Real-Time Strategy]]
* Last level of ''VideoGame/NexusTheJupiterIncident'' where you're fighting in subspace.


[[folder: Rhythm Games]]
* ''VideoGame/BeatmaniaIIDX'' has been doing this a lot in its recent installments, usually with [[TrueFinalBoss Extra Stages]]. The background video usually has an overlay representing the personification of the boss song.
* [[BonusBoss Pander's]] stage in ''VideoGame/BustAGroove 2'' turns into one of these halfway into the song ([[https://youtu.be/Xynmhk1zC8Q which is trippy in its own right]]).
* If you manage to hit Cool mode on the fifth stage of ''VideoGame/ParappaTheRapper'', the gas station back alley you were standing in turns into a psychedellic rainbow background with the faces of your teachers appearing as you continue freestyling. Oh, and you start chasing a toilet on a train track. ItMakesSenseInContext.

[[folder: Roguelike]]
* The final battle of ''VideoGame/PokemonMysteryDungeonGatesToInfinity'' takes place in a swirling purple void with chunks of ice drifting about; an appropriate setting for a fight [[spoiler: against a true EldritchAbomination]].
** ''VideoGame/PokemonSuperMysteryDungeon'''s final battle is likewise staged upon a field of stars with the glowing silhouette of [[spoiler:the Tree of Life]] in the distance, which also serves as the background of game's boxart.
* In ''VideoGame/NuclearThrone'' [[spoiler: Throne II]] is fought on a small chunk of land inside of a massive purple portal.

[[folder: Role-Playing Games ]]

* A rare Western-RPG example: ''VideoGame/TheElderScrollsVSkyrim'''s final battle against Alduin takes place in [[spoiler:Sovngarde (which is basically, in keeping with Skyrim's HornyVikings motif, an expy of Valhalla)]], and boy is it heavily saturated with color, especially as you look up and see Alduin approaching.
* ''VideoGame/ActRaiser'': In the [[BossRush finale]], The Master faces Tanzra and co. first in a cloudy wasteland, then in a starry galactic field.
* Most ''Franchise/FinalFantasy'' games after that have their climactic battles on Amazing Technicolor Battlefields.
** Averted in I - III, but only because there was next to no background. Played completely straight in the remakes though.
** The fight against Zeromus in ''VideoGame/FinalFantasyIV''. The swirling background scrolls behind him and your party as you fight, and his most powerful attack, "Big Bang", will actually reverse the scrolling for a few seconds before dealing massive damage to your party.
** You get the same deal in ''VideoGame/FinalFantasyV''. One of Neo-Exdeath's attacks even declares "The laws of the universe mean nothing!"
** [[JustifiedTrope Justified]] in ''VideoGame/FinalFantasyVI'', as Kefka already succeeded in blowing up the world halfway through, and the battlefield you're facing him on is his tower/the ruined sky.
** ''VideoGame/FinalFantasyVII'' also throws in the OneWingedAngel and OminousLatinChanting for good measure.
** ''VideoGame/FinalFantasyVIII'''s final castle is bookended by a psychedelic trip forward through time, and then an even trippier journey backwards as [[spoiler:Ultimecia attempts to "[[FunetikAksent kompress]]" all of time into a single immortal moment for...[[MotiveDecay some reason.]]]]
*** Ultimately, it's a subversion, as the final boss takes place in a [[spoiler: ''pitch black void'']].
** ''VideoGame/FinalFantasyIX'' has the Amazing Technicolor ''Battle'' against Ozma.
** ''VideoGame/FinalFantasyX'''s fight with [[spoiler:Yunalesca]], while NOT the final boss battle in the game, makes use of a totally ''cosmic'' AmazingTechnicolorBattlefield. Complete with floaty ruins! The final battle against [[spoiler: Yu Yevon and the aeons]] is also an example, only in this one you have to [[spoiler:''fight'' the floaty ruins!]]
*** To elaborate, when you fight [[spoiler:Yu Yevon and the aeons]], you are on a giant version of [[spoiler:Jecht's]] sword in the middle of a swirling yellowish void. The boss immediately before Yunalesca also deserves a mention. Your battle team is standing on glowing symbols representing the temples that you have visited throughout the game. Each character can teleport to any of the unoccupied symbols. If you summon an aeon, you get moved to one of three floating rocks so the boss can kill the aeon in one hit. [[AcidTripDimension The background is a blue-tinted starfield with a pattern swirling both upward and downward from a ring of symbols corresponding to the aeons]].
** ''VideoGame/FinalFantasyXI'' expansion ''Chains of Promathia'' has a rather neat final battlefield with the characters [[spoiler:fighting above Vana'diel. In space.]]
** ''VideoGame/FinalFantasyXIV'' expansion ''Heavensward'' features a particularly fine example of this trope in the final battle with [[spoiler: King Thordan and his Knights Twelve, with the interior of the Triad Control room changed to a brightly lit starry fields and backgrounds during each successive wave of attacks against the player characters.]]
** ''VideoGame/DissidiaFinalFantasy'''s stages are the final dungeon or boss arenas from the main series, so naturally it woulf feature these sort of battlefields.
* Par for the course in ''VideoGame/{{Suikoden}}'' games when the final boss is an incarnation of a True Rune. Averted in IV when facing the [[GiantSpaceFleaFromNowhere giant tree from another dimension]] whose presence is hinted at during the game. You just fight it in the same room where it's been sitting.
* In ''VideoGame/{{Earthbound}}'' every battle takes place in a swirling background, from [[EverythingTryingToKillYou cultists to killer bees to the hippie down the street]]óbut the final boss [[spoiler:''is'' the trippy background.]]
** ''VideoGame/{{Mother 3}}'' continues this trend just as well-- The boss battle against the Masked Man is pictured above (the second from the bottom). As the battle progresses, however, the background gradually distorts and loses its color [[spoiler: as a symbolic representation of Masked Man slowly coming to his senses and remembering his true identity.]]
* In ''Franchise/KingdomHearts'', the final dungeons ''and'' bosses of each game are usually in an ethereal, unsettling realm on the edge of reality. Not all of them are used for bosses, either.
** Both of the final bosses of [=PS2=] games seem to be subversions: The first has the final fight in the heart of reality itself, a dark featureless void (barring the EldritchAbomination FinalBoss), and the second (presumably) takes place in the remains of the VeryDefinitelyFinalDungeon....which is a ''white'' featureless void. There are other battles that play it straight, though
*** In the first game, the battle against the Behemoth inside Hollow Bastion's Keyhole takes place in a more conventional AmazingTechnicolorBattlefield. The End of the World gives this to the regular enemies too, due to it being a mix of abstract dimensions, phantasmagoric landscapes, and very colorful rooms.
*** The first Xemnas battle in ''VideoGame/KingdomHeartsII'' takes place in Memory's Contortion, a rainy version of Memory's Skyscraper that just has the one building with wavering images of a city off in the distance. The second battle against Armored Xemnas happens in a crumbling version of the World that Never Was with colorful surfaces and streams of energy everywhere. Sora and Axel fight a swarm of lesser Nobodies in Betwixt and Between, which is the abstract interior of a portal between the virtual Twilight Town and the World the Never Was. Finally, the Paradox Cup battles in Olympus Coliseum are all set on platforms in a swirly green vortex that may or may not be in the Well of Souls.
** The DS game then averted it by having the boss fight move between rooms of different worlds for each round, and then back to the place seen just before the battle for the last one. [[spoiler:The real final boss doesn't shift from Memory's Skyscraper and is much easier to take down after this.]]
** ZigZagged in ''VideoGame/KingdomHeartsBirthBySleep''. Terra and Aqua have fairly mundane Final Boss arenas, though Terra's becomes more colorful during the [[SequentialBoss second stages]] of his fight due to him summoning chains of light around the plateau to trap his enemy. Ventus has his [[DreamWorld Awakening platform]] with a stained glass floor and black void. The [[UpdatedRerelease Final Mix]] adds another technicolor field for Aqua, not [[CallBack too far from the first game's final world.]]
** Played straight with the two fights against [[spoiler: Ansem]] in ''VideoGame/KingdomHearts3D''. The first takes place in a colorful void with twisting tendrils of darkness in the background. The second takes place in a canyon within what appears to be the Realm of Darkness, with eerie glowing lights shining through cracks in the dark surroundings and the aforementioned void relocated to behind the now StationaryBoss. [[spoiler: Young Xehanort]] also gets in on this, his initially plain clockwork dimension becoming progressively more colorful as you damage him, causing the hourglasses surrounding the platform to shatter one by one, scattering their colorful sands into the air, followed by him summoning a clock that covers the entire battlefield in swirly colors. And the very final fight, against [[spoiler:a nightmare version of Ven's armour]] takes place on [[spoiler:Sora's Awakening platform]], but totally covered in darkness, and periodically switching between black and white.
* ''VideoGame/DarkCloud's'' final boss Dark Genie teleports you to a kaleidoscopic purple space, in which you walk on air - transforming into a tentacle monster to make the experience that much more surreal.
* ''VideoGame/ChronoTrigger'' has quite a few. Lavos's first form (which you get to see early in a HopelessBossFight) takes place on a blueish background with ripples everywhere, as does a late-game boss intimately connected with Lavos. Lavos's "middle" form isn't one of these, but his final form takes place on a field of swirling colors, behind which scenes from the world's history can be seen. Altering the scenes is even one of the boss's abilities "Time warp", and it gains a specific attack spell with each different background. But before all of that, the magician Flea gets a starfield background, even though he's merely a mini-boss.
** The Darkness Beyond Time from ''VideoGame/ChronoCross''. Slightly before that, the battle with the Dragon God might also count, as he tends to change the background on you from time to time.
* A variation appears in the original ''VideoGame/ShadowHearts''; the final battle takes place in space, atop a summoning circle for a [[SufficientlyAdvancedAlien godlike alien]], projected by a castle/biomechanical space station.
* ''VideoGame/LegendOfLegaia'' had a particularly trippy one. The only ([[HandWave deeply unsatisfying]]) justification given was that the battle took place in the belly of a giant creature.
* In ''VideoGame/TalesOfPhantasia'', the final fight with Dhaos, after he [[OneWingedAngel transforms into his true form]], takes place in outer space, apparently high above the protagonists' home world.
** ''VideoGame/TalesOfSymphonia'', when you fight [[BonusBoss Maxwell]], the [[{{Magitek}} Sin Incarnates]], and the [[OneWingedAngel Robot version of the]] BigBad. Also any fights in the [[BrutalBonusLevel book, Forbidden Anamnesis]]. And the area before the TheVeryDefinitelyFinalDungeon, would count as well.
** ''VideoGame/TalesOfTheAbyss'', when you've beaten the BigBad, [[spoiler:Tear will begin singing a lullaby, while [[TheHero Luke]] uses his powers to stop an uber attack from said BigBad, the battle background shifts into this blue [[InstantRunes thing with mysterious symbols every where]], and while this is going on, everyone has infinite HitPoints, and you can't pause, or open the menu, or see the status of your characters. You just fight until Luke performs a CrowningMomentOfAwesome.]]
** ''VideoGame/TalesOfVesperia's'' final battle starts off on regular stone platform, but gets more like this trope with each form of the boss you defeat.
** In ''VideoGame/TalesOfHearts'', you fight the final final boss in the JourneyToTheCenterOfTheMind of the BigBad, and the BonusBoss at the bottom of some sort of warped space.
** ''VideoGame/TalesOfEternia'' has the final boss fight with a background of black kaleidoscopic swirling.
* The battle against [[BonusBoss Culex]] in ''VideoGame/SuperMarioRPG: Legend of the Seven Stars'', as an homage to ''Franchise/FinalFantasy'' and its use of this trope. Given Culex is traveling the MultiVerse and the visual similarity, [[ArcWelding it may be the same location]] as the Interdimensional Rift ''VideoGame/FinalFantasyV''.
* The final battle in ''VideoGame/{{Xenosaga}} Episode I'' takes place in a multicoloured haze, with no attempt at justification. The battle music also changes from the standard music used in each other battle in the game (including boss battles) to an arguably [[SoundtrackDissonance calmer, less tense piece of music]].
* The fight against Umaril in ''VideoGame/TheElderScrollsIVOblivion'' expansion pack ''Knights of the Nine''. You go through the Final Dungeon, defeat him once, then you fight him again whilst hovering thousands of meters over the Imperial capital.
* The final battle in ''VideoGame/TheLegendOfDragoon'' takes place in a surreal landscape that changes entirely from time to time as the fight progresses.
** You can invoke these more or less at will by using Dragoon Specials.
* All of the final dungeon in ''VideoGame/PhantasyStarIV'', and the final (hard and above) part of the Dark Falz battle in ''VideoGame/PhantasyStarOnline''. Somewhat expected in the former, as the final dungeon (which seen from the outside is a hole in the ground ''visible from space'') is [[spoiler: The Profound Darkness forcing its way through the final layers of the seal (which itself takes the form of a solar system) keeping it locked outside of reality.]]
** Done in the previous Installments also except ''VideoGame/PhantasyStarI'' in which it was just a black background (in itself unusual, as almost every other fight featured a background), but remade into a space like background in the Remake.
* The final battle of ''VideoGame/BatenKaitosOrigins'' against [[spoiler:Verus-Wiseman]] takes place in a starscape.
* In ''VideoGame/{{Persona 3}}'' and ''[[VideoGame/{{Persona 4}} 4]]'' do this whether it's just a regular field enemy or a boss. ''VideoGame/{{Persona 3}}'' really takes the cake for the final boss in [[spoiler: both The Journey and The Answer. The Journey deserves special mention because you are fighting inside Nyx itself, and boy doesn't she look awesome!]]
* Dimentio from ''VideoGame/SuperPaperMario'' fits this trope. Whenever you fight him, he teleports you to his own 'Dimension D', in which his power becomes 256 times stronger. Regrettably, the player's power is also increased, therefore nullifying the effects.
* ''[[Franchise/SaGaRPG SaGa]]'' uses this quite a few times throughout the series:
** Every ''VideoGame/RomancingSaga'' game has this for the final boss:
*** You fight Saruin in a sky-like area surrounded by pillars. Stays the same in the remake, except the pillars play an important role and the characters and Saruin are on a platform surrounded by them.
*** Death is fought inside some strange type of ruin that mixes a window behind him and the sun above him (Strange given where you are).
*** Schirach is fought on a bunch of pieces of what remains of the inner sanctum of the Shadow Palace.
*** You fight the Seven Heroes in a distorted realm.
*** You fight the Destroyer on a scrolling psuedo background, which also switched to an a drug trip like battlefield if it used its "Total Eclipse" technique.
** Also applies to some final bosses in ''VideoGame/SagaFrontier'':
*** Boss X is fought in a realm of a swirling mass of color, giving it a "3D glasses"-like effect. In fact, invoking this trope is pretty much his special power: when his {{mooks}} are in trouble, he'll send them and the heroes to one of these (apparently called the "4th Dimension Magisphere"), giving his mooks a substantial boost in HP and power.
*** Orlouge has a kaleidoscope-esque background.
*** Genocide Heart can shift the background to any virtual realm it had.
*** Master Ring is fought directly above the reborn Margmel.
** The final boss in ''VideoGame/UnlimitedSaga'' is fought in outer space on the moon, and you're drawn in towards the second moon on the 4th form.
* The battle against the goddess Myria in ''VideoGame/BreathOfFireIII'' is a fine example of this, as you are suddenly on a small floating platform and facing a huge [[OneWingedAngel serpentine monster.]]
* In the [=PS1=] version of ''[[GameMaker RPG Maker]]'', the final battle of the demo ''Gobli's Adventure'' has Gobli fighting solo against [[spoiler:Neko]] in a void with colorful rays of light radiating from a single point (with [[spoiler:Neko]] placed so that it looks like he's in the center of it in the overworld). This same background can be used in one's own game.
* The final battle of ''VideoGame/{{Freelancer}}'' takes place in a gigantic [[http://en.wikipedia.org/wiki/Dyson_sphere Dyson Sphere]]. We're talking way larger than any planet; Dyson spheres have a radius of about 150 million kilometers. The whole inside of this thing is covered in one big city.
* Gleefully {{Lampshaded}} by Bowser in ''[[VideoGame/MarioAndLuigiBowsersInsideStory Mario & Luigi: Bowser's Inside Story]]''. He comments that the current final boss has to have good taste to pick such an awesome battlefield for the climactic showdown.
** The setting for Bowser's part of the final boss fight is actually dull in comparison to where Mario and Luigi's part takes place, however; it being in an unspecified, but extremely psychedelic colored part of Bowser's body with parts of the floor and background glowing on and off.
** In VideoGame/MarioAndLuigiPartnersInTime, the final battle with [[spoiler:Elder Princess Shroob]] takes place on a floating platform in a stormy sky.
** The final battle in VideoGame/MarioAndLuigiDreamTeam already has a multicoloured battlefield floor on a creepy rooftop arena, but it then also inverts this trope by having an Amazing Technicolor BOSS in the form of the rainbow coloured, glowing [[spoiler:Dreamy Bowser]].
** VideoGame/MarioAndLuigiPaperJam' final boss battle, [[spoiler:Shiny Robo-Bowser]], takes place in front of a glowing, red-colored void at the top of [[spoiler:Neo Bowser's Castle.]]
* In ''VideoGame/DotHackGU'', in addition to all the Avatar battles and the areas outside the normal game, the very final battle against [[spoiler:Cubia]] takes place in the middle of a yellow-ish tunnel while your party stands on a semi-translucent floor. Well, you have to fight the thing ''somewhere''.
* The final boss in ''VideoGame/{{Dubloon}}'' takes place the darkness of [[spoiler:greed]], with aura of light emanating from the boss.
* The FinalBoss battles of both ''VideoGame/{{Ys}} I'' and ''II''. The former arena is in a starfield, the latter is surrounded by a sea of flames. Likewise for most final battles in the rest of the series.
* ''VideoGame/SeikenDensetsu3'' has two such battles: Zable-Fahr, the Dragon God of Darkness, and the final BigBad in both Hawk/Lise and Carlie/Kevin's storylines.
* In ''VideoGame/LegendOfMana'', the battles against the Lord of Jewels and [[spoiler:The Mana Goddess]] take place in such a battlefield.
* In ''VideoGame/EpicBattleFantasy 3'', the final battle against Akron is fought in a space-like void. Justified in that [[spoiler:Akron's very unsealed presence warps space]].
* ''VideoGame/ArTonelico2'' has an odd variation in that ''you'' cause this to happen. [[GameBreaker And then the enemy dies to your]] [[UpToEleven hypercharged]] [[MagicMusic song magic.]]
* The final boss in ''VideoGame/{{Xenoblade}}'' is fought as you fly through one of these. In the second phase, he shifts the scenery between this and a beautiful blue sky when he uses certain attacks.
* ''VideoGame/TheGranstreamSaga'' has '''two''' of these. One is against the final boss, naturally, who is a sapient-can-comprehend-mortals JerkAss EldritchAbomination, and earlier, in a MadScientist's castle. The battle is against his experimental world-ending giant creature, and you have to destroy its heart from inside. While you're fighting the heart blood vessels can be 'seen' transparently from above as if you're really looking down into the battlefield, and the entire room pulsates and shifts with his heartbeats. Both trippy and disorienting.
* The battle against [[spoiler:Mewtwo]] in ''VideoGame/PokemonStadium'' has you fighting him in a void filled with various shades of blue/green and purple with a white Poké Ball design in the center of the battlefield.
* Mostly averted in the handheld ''Pokémon'' series, where the Champion is normally battled in a small, plain-ish throne room. Played straight however in ''VideoGame/PokemonBlack2AndWhite2'' versus [[spoiler:Iris]], where the battlefield looks to be in outer space with colorful stars aplenty.
* In ''VideoGame/PokemonXAndY'', the title legendaries Xerneas and Yveltal are fought in a massive chamber made of crystals and on ''the event horizon of a black hole'' respectively. And it's [[VisualEffectsOfAwesome awesome.]] Then you fight [[spoiler:Team Flare's boss, Lysandre]] on the sun.
* ''VideoGame/DarkSouls'' is generally too gritty to feature a trope like this, but it does play with the trope once. It's not even remotely close to the final boss, but the battle against the Four Kings takes place in the Abyss. What is the Abyss, you may ask? It's complete, uniform, total darkness in every direction. No terrain. No horizon. No nothing. Just blackness everywhere.
* ''VideoGame/DarkSouls2'' gets in on it with the Crown of the Ivory King DLC. 99% of the DLC takes place in a frozen castle-city... and then the final battle is on a platform suspended in mid-air over a sea of fire with tree roots that look suspiciously like the Bed of Chaos climbing into the sky, while enemies emerge from portals filled with dark flames.
* The TrueFinalBoss of ''VideoGame/{{Undertale}}'' starts out with a plain black background just like every other fight in the game, but as soon the music kicks into gear it erupts into a psychedelic lightshow of rainbow colors.
* In ''VideoGame/SandsOfDestruction'', the Primal Cataract contains a chunk of rock for each of the seven colors of the rainbow. When you finally reach the end to fight [[spoiler:Lacertus Rex - the real one -]] it has a flowing, twirling rainbow. [[spoiler:But this isn't even the final dungeon, it's just the gateway to it.]]
* The final battle of ''VideoGame/BravelyDefault'' takes place in the Infernal Realm, with a variable background that eventually [[spoiler: begins to show the player's face by using the 3DS's front camera.]]
* In ''VideoGame/RivieraThePromisedLand'', the final battle against [[spoiler: Seth-Rah]] happens in the Maze of Shadows, with a purple background and some floating triangles. The place can be seen in the page image above.


[[folder: Shoot Em Ups ]]

* ''VideoGame/StarFox'' had this for its classic trippy final boss fight against Andross, with a swirl of colors. ''VideoGame/StarFox64'' continues the tradition with a similar eery background, which actually gets weirder when it becomes ''less'' trippy as Andross [[OneWingedAngel shows his true form]].
** There were also two secret paths in the asteroid belt that sent you throguh a trippy alternate dimension asteroid belt that nobody in game notices. The second of these is an alternate ending with its own FinalBoss. ''64'' also had two hidden psychedelic warp gates.
* The final battle of ''VideoGame/ChimeraBeast'' takes place in such an environment, the screen from the intro in fact, located at the center of an atomic explosion.
* In the battle with the TrueFinalBoss in ''VideoGame/{{Hellsinker}}'' practicly goes from somewhat confusing to downright MindScrew. [[http://www.youtube.com/watch?v=24fU9MbKcS8 Must be seen to be belived]].
* ''VideoGame/{{Touhou}}'' kind of has this for ''every'' boss half the time, as declaring a spellcard changes the background to something abstract. But probably the most in the spirit of the trope is the fight against Toyosatomimi no Miko: The entire final stage is a blue void with spirits of various colours in the background.


[[folder: Simulation Games ]]

* Manages to even show up in ''VideoGame/PokemonSnap'', the ''[[FirstPersonSnapshooter photo-safari]]'' game. After getting photos of all the other Pokémon, Professor Oak sends you after Mew by launching you on a rather trippy voyage through a strange cosmic realm out of a mid-80s Heart Video.
* You get [[spoiler:sucked into another reality (with creepy music to add)]] in the final mission of ''VideoGame/AceCombat3Electrosphere''. Though if [[spoiler:you manage to get straight B's, or better, on all of the other missions, including that one, you get [[BonusStage yet another mission]]]].


[[folder: Stealth Game ]]

* The Rectum in ''VideoGame/MetalGearSolid2''. Having fought your way through the corridors of a high-tech but vaguely naval-looking [[spoiler:submarine]], you arrive in a gigantic void with a platform made of what appears to be data. There are no visible walls, the floor is covered in shadows and there's mist above you, and it's difficult to tell whether you're inside the thing or on top of it. This is lampshaded in ''Substance'', where one of the non-canon Snake Tales uses the setting to represent [[spoiler:the void between dimensions]].


[[folder: Turn-Based Strategy ]]

* Last part of the last level of ''VideoGame/TacticsOgre: The Knight of Lodis''.


[[folder: Web Games ]]

* ''VideoGame/RobotUnicornAttack'', [[TastesLikeDiabetes ever so much]].


[[folder: Non-Video Game Examples ]]

* ''Series/SpaceSheriffShaider'' has the Strange Realm.
* In ''Webcomic/{{Adventurers}}'' Khrima constructs an elaborate hollow sphere with displays on the inside surface so that the climactic BossFight can be fought seemingly suspended in swirling purple stuff.
-->'''Khrima''': [[http://www.adventurers-comic.com/d/20040629.html Because... you can't have a final boss fight... without the psychadelic twirling coloured background!]]
** The background gets progressively destroyed during the battle until the entire sphere has been demolished.
* ''Franchise/DragonBall'':
** The entire Other World in the ''Anime/DragonBallZ'' NonSerialMovie ''Fusion Reborn''; the ground is barren and cracked, but the sky is bright with colorful clouds and strange orbs floating everywhere. How little it makes sense just helps to show just how badly BigBad Janemba messed things up.
** In ''Anime/DragonBallSuper'', near the end of the Tournament of Power, the World of Void takes on this appearance once Toppo [[spoiler: becomes a God of Destruction and fractures the entire arena.]]
* In the webcomic ''WebComic/KidRadd,'' our heroes have entered an RPG game. The battles take place in these, where all you can see is the enemy against the swirls and stripes. The game is based off of ''VideoGame/{{Earthbound}}'', of course. Radd and his friends enjoy the trippy feel, for it's a nice change of pace for them; they're more used to platformers.
-->Radd: Far out! This system rocks!
-->Itty Bitty: Dig it.
-->G.I. Guy: Is this a battle screen or a disco?
* The fight between [[spoiler:Yuki and Ryoko]] in ''LightNovel/HaruhiSuzumiya'' takes place on a constantly shifting technicolour background.
* The final battle(s) against the [[spoiler:Anti-Spirals]] in ''Anime/TengenToppaGurrenLagann'' are set in outer space, in a very colorful [[spoiler:alternate dimension.]]
* Another example comes from ''Anime/YuGiOh5Ds''. Activating the Speed World spell card does this, minus the ever-changing colors. The same is done with the Neo Space card in ''Anime/YuGiOhGX'', though the entire battlefield is a rainbow-colored shimmering landscape, including the floor.
* Zero time from ''Anime/StarDriver'' fits this trope to a T.
* This is the second-most attention-grabbing feature in Jersey Jack Pinball's ''Pinball/TheWizardOfOz'' (after the HD screen in the backbox) -- the entire table uses color-changing LED lights to change the color of playfield targets and indicators throughout the game.
* In ''FanFic/CrownsOfTheKingdom'', the final battle in Inpotentia is this.
* When fighting the Glumdroodler in ''Webcomic/AwfulHospital''.
* A UsefulNotes/McDonalds location in UsefulNotes/SanDiego had its interior modeled like this in the 1980s, including starry space-painted walls and ceilings with [[UnrealisticBlackHole electric-blue black holes]], [[AsteroidThicket asteroids]], and [[ApocalypseWow flying rubble]]. Adding to the effect were actual props in the form of [[{{Atlantis}} broken]] [[AncientGreece Greek]] [[CrystalSpiresAndTogas columns]], [[PowerCrystal formations of crystals]], and jagged glass, accentuated with rings of red neon lights. And also, [[EverythingsBetterWithPenguins penguins]]. Pure awesome, glorious 80s cheese. View some images [[http://m.imgur.com/a/G0K3f here]]. In order to apply its new, hip coffeehouse aesthetic to all its restaurants, however, [=McDonald=]'s renovated and stripped the decor.
* In One Piece, within the special Heart of Gold, for the final battle the inside of the anglerfish reacts to the pure gold, causing incredible displays.
