->'''Hermes:''' We're jerked! Nothing can stop a monster that big!\\
'''Prof. Farnsworth:''' Nothing except an even more equally big monster!
-->-- ''WesternAnimation/{{Futurama}}'', "[[Recap/FuturamaS2E16AnthologyOfInterestI Anthology of Interest I]]"

What's better than having a huge monster? Having two huge monsters! Then making them fight each other!

A staple of monster- and {{kaiju}}-focused movies (but in no way limited to that medium), where two giant creatures square off in a no-holds-barred fight, just because they can. Makes for great visuals and even more collateral damage. As a highly visual trope, only examples shown on-scene should be added.

The word ''creature'' should be interpreted quite liberally here. It matters more how it looks than how it functions. Giant humanoid robots and other HumongousMecha are explicitly included. For battles between giant machines and biological creatures see MechVsBeast.

In no small degree builds on RuleOfCool and CoolVersusAwesome. See also MonsterMash. PrimateVersusReptile is an especially common variant, thanks to the iconic fight scene in ''Film/KingKong1933''. Following ''Film/JurassicParkIII'' (2001), the SpinosaurusVersusTRex pairing also gained some popularity.

Any film set in a LostWorld or HollywoodPrehistory setting will likely have such a scene.

Examples are generally sorted chronologically.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* The SuperRobotGenre, starting with ''Anime/MazingerZ'', is based on this with giant HumongousMecha battling giant creatures or [[{{Robeast}} robots]] (depending on the work).
** The movie "''Anime/UFORoboGrendizer, Manga/GetterRobo G, Anime/GreatMazinger: Kessen! Daikaijuu''" has these mecha (from different shows) allies to battle a giant prehistoric monster (more bigger than them) surviving unknowingly in the depths of the oceans.
* ''Manga/AttackOnTitan'': The Titans don't normally fight each other and go exclusively after humans, but starting on the "Battle Of Trost District" Arc, the Rogue Titan was introduced and it exclusively attacks other Titans [[spoiler:because said Titan is Eren Yeager himself, having come into his power as a Titan Shifter]]. Naturally, this leads to Titan duels and ''brawls'' [[spoiler:as more Shifters are revealed]] that can completely wreck cities as if they're made of Styrofoam.
* ''Anime/TheBigO'': the eponymous HumongousMecha battles other robots (called [[AMechaByAnyOthername Megadeus]]) and a few giant monsters over the course of the series.
* ''Manga/ACertainScientificRailgun'': One such battle occurs at the end of the Dream Ranker Arc between [[ShockAndAwe Mikoto Misaka]] manipulating a giant skyscraper-sized iron-sand puppet against the [[RobotMe Doppelganger of Ryoko Kuriba]] having created a similarly-sized puppet made of city debris.
* The ''VideoGame/{{Darkstalkers}}'' series is usually about human-sized monsters fighting each other, but the ''[[Anime/NightWarriorsDarkstalkersRevenge Night Warriors]]'' OVA adaptation decides to kick things up a notch in the final battle against the BigBad, where [[spoiler: a [[HumongousMecha giant-sized Huitzil robot]] appears specifically to fight Pyron. Normally the same size as the rest of the cast, Pyron in turn grows to the same size to do battle.]]
* In ''Anime/DigimonAdventure2020'', there are plenty of large Digimon running around and multiple fights that could be said to be this, like Mugendramon vs. [=DoneDevimon=], but special mention has to go to Episode 50's clash: [[spoiler: Goddramon and Holydramon vs. Milleniumon. When Milleniumon is put on the back foot by the two holy dragons teaming up on him, he evolves into the absolutely ''colossal'' [=ZeedMilleniumon=], who makes the aforementioned Goddramon and Holydramon (who themselves make average Kaiju-sized Digimon like [=WarGreymon=] and [=MetalGarurumon=] look like ants in comparison) absolutely microscopic.]]
* ''Manga/FairyTail''
** Several of these happen, usually whenever [[OurDragonsAreDifferent dragons]] are involved. Makarov's Titan form versus Acnologia at the end of the Sirius Island Arc, Atlas Flame versus Motherglare while Natsu and [[spoiler:[[FutureMeScaresMe Future Rogue]]]] fight on their backs at the climax of the Grand Magic Games, and [[spoiler:Igneel]] versus Acnologia near the end of the Tataros Arc.
** {{Exaggerated|Trope}} in ''Manga/FairyTail100YearsQuest'' during the battle between [[GreenThumb Wood Dragon God Aldoron]] and [[spoiler:Gajeel [[{{Sizeshifter}} supersized by Brandish's Command T magic]]]]. Most dragons are about the size of large buildings. Aldoron's ''height'' alone is about that of a large mountain (and adding in his length would be more comparable to a small ''mountain range''), while his opponent has to [[MakeMyMonsterGrow be super-sized via magic to a comparable size explicitly compared to a mountain]].
* In the final installment of the anime Godzilla trilogy, ''Anime/GodzillaThePlanetEater'' there is one between Godzilla and his arch-enemy Ghidorah.
* While most dragon fights in ''Manga/MissKobayashisDragonMaid'' involve one or both parties [[{{Weredragon}} in human form]], Tohru and Elma's falling out in the backstory had them both fighting in full dragon form, with the battle reducing an entire city to rubble and the final clash resulting in a PillarOfLight so large that it was visible from space.
* ''Anime/{{Naruto}}'' has Bee/Gyuuki and Naruto/Kurama battling 5 other tailed beasts. The resulting brawl is so intense and fast-paced that it even leaves Guy [[ShoutOut comparing it]] to Film/DestroyAllMonsters. And this is ''before'' they pull out their [[FantasticNuke Tailed-Beast Bombs.]]
** Others include Gaara's attack on the Village, which was combated by Naruto and Gamabunta (with a combined transformation into the Kyuubi), Hashirama's Wood Style summons against Madara's Kyuubi+Susanoo, Kurama vs the Oostutsuki statue in ''The Last'', and ultimately, Naruto/Kurama's battle against Momoshiki in ''Boruto'', joined in with Sasuke'a Sunano'o.
* ''Anime/NeonGenesisEvangelion'': The eponymous [[HumongousMecha EVA mechs]] are used by NERV to fight [[OurAngelsAreDifferent angels]], which resemble [[AlienGeometries weird]] [[{{Kaiju}} giant aliens]] with no uniform appearance. the only thing that qualifies them as "angel" is that they have a "blood pattern blue", and halos.
* ''Franchise/OnePiece'': On Little Garden Island, there are two giants who have battled against each other for about a century. They've forgotten the cause for their battle, and now they just do it for fun.
* ''Anime/PokemonTheSeries'': Several battles between [[OlympusMons legendary Pokémon]]: Groudon vs. Kyogre, Dialga vs. Palkia, etc. Then there are a few interesting ones involving giant versions of normal-sized Pokémon.
* The final episode of ''Anime/TabooTattoo'' involved [[spoiler: Touko and Izzy having fused together fighting Arya, who had fused with her sisters.]]
* ''Anime/TengenToppaGurrenLagann'' starts off as a typical battle between HumongousMecha who over the series [[SerialEscalation escalates]] into galaxy sized ones.
* ''Anime/YuGiOh'': Several battles between [[OlympusMons Egyptian God Cards]], between the God Cards and the [[PhysicalGod Great Leviathan]], and between [[BigBad Zorc]] and [[AttackOfThe50FootWhatever Exodia]], the [[OurDragonsAreDifferent Blue-Eyes Ultimate Dragon]], and [[BigGood Horakhty]].
[[/folder]]

[[folder:Arts]]
* ''Art/CartaMarina'':
** While Ziphius, a "terrible sea monster" (actually a swordfish), is swallowing a whole seal, it is itself attacked by an unnamed monster which is sinking its teeth into Ziphius' side.
** South of the island of Tile, a whale (balena) is being attacked by an orca.
[[/folder]]

[[folder:Comic Books]]
* One issue of the ''Series/BuffyTheVampireSlayer'' Season Eight comics features a fight between Giant Dawn and Mecha-Dawn, while a delighted Xander watches.
* Near the climax of Comicbook/EarthX, a cohort of [[SufficientlyAdvancedAliens Celestials]] have invaded New York City. Reed Richards and Black Bolt work together to summon the one being who can fight them. The Celestials may be the size of buildings, but [[spoiler:Galactus]] is the size of ''the horizon.''
* In ''ComicBook/TheGoon'', the title character is temporarily transformed into a giant gorilla [[PrimateVersusReptile so he can fight]] El Hombre Lagarto.
* ''ComicBook/{{Kaijumax}}'' is an odd example: the series is about a prison for giant monsters, and it's told on their scale. They may not ''look'' giant to the reader, but they definitely are.
* The climactic battle in ''[[ComicBook/{{Lanfeust}} Lanfeust de Troy]]'' is fought between giant energy clones of [[TheHero Lanfeust]] and [[BigBad Thanos]] over Eckmül.
* Marvel's ''ComicBook/ShogunWarriors'' series is built around this trope. The titular trio of HumongousMecha fight a range of equally huge {{Kaiju}}, robots and {{Magitek}} horrors (and some that are much, much bigger). There are a handful of scenes where the Shogun pilots end up facing smaller foes without their giant robots, but they're very much the exception to the rule.
[[/folder]]

[[folder:Documentaries]]
* ''Series/PrehistoricPlanet'':
** The first episode features a sequence between two adult ''Mosasaurus'', the planet's largest and most powerful carnivore during the end of the Late Cretaceous. The narration states such battles can be deadly, and fossils of mosasaurs have been discovered with teeth of other mosasaurs embedded in them.
** The second episode features two huge male ''Dreadnoughtus'', each nearly fifty metric tonnes, battling for control of the females in the mating grounds. The battle is brutal, with both animals slamming into each other on their hind limbs, stabbing with their thumb claws, and raking each other with their teeth. Because they're so huge, it takes tremendous energy to fight like this, and the loser dies from exertion.
** The third episode features a fight between two ''Quetzalcoatlus'', one of the largest flying animals to ever live, specifically instigated between a mother defending her eggs and a rival female attempting to destroy the nest to remove competition for her own offspring.
** The tenth episode features a battle between two male ''Triceratops'' (an old one and a younger one) fighting for mating opportunities. The younger male is six tonnes, while older male is said to weigh ''ten tonnes''.
** The tenth episode also features a fight between a ''Tyrannosaurus'' (one of the largest ever land predators) and a pair of ''Quetzalcoatlus'' (one of the largest ever fliers), though unlike the other examples, this combat consists mostly of posing and threat displays, and never gets physical apart from a few brief pecks from the ''Quetzalcoatlus''.
* ''WesternAnimation/SeaMonstersAPrehistoricAdventure'': A 29-foot ''Tylosaurus'' finds himself fighting a larger individual of the same species. The skirmish concludes with the death of the smaller tylosaur.
[[/folder]]

[[folder:Fan Works]]
* ''Fanfic/CatchYourBreath'', a ''Franchise/{{Naruto}}'' fanfic, there have been several of those so far (and it's likely more will come).
** [[spoiler:Isobu and Shukaku battle it out in the shared Tailed Beast [[{{Pun}} mind]][[ShoutOut skype]] in order to save Gaara. This was later revealed not to have been serious, but it was impressive.]]
** During the fight between Kei (the protagonist) and [[spoiler:Minato]], the battle eventually (spectacularly) escalates into this.
* ''Fanfic/TheBridge'': Considering half the roster have true forms over 80 meters tall, this is a given. Specific examples include-
** The opening fight, a full melee with almost every single member of the Terran Defender, Mutation, GDF, and Coalition factions slugging it out. Special focus on Godzilla Junior vs. Xenilla and Mothra, Anguirus, and Rodan vs. Destroyah. [[labelnote:Result]]Draw due to Dimension Tide hitting all six of them to unknowingly transport them to Equstria.[[/labelnote]]
** Anguirus with help from Rainbow Dash and Rodan vs. Gable's Greed Growth enhanced dragon gang [[labelnote:Result]]CurbStompBattle in the heroes' favor due to Anguirus knowing how to fight and being immune to dragon fire.[[/labelnote]]
** Mothra Lea vs. Albino Hyper Gyaos [[note]]later called Irys[[/note]], several Super Gyaos, and a few dozen Gyaos [[labelnote:Result]] With help from Twilight Sparkle and some quick thinking, Lea manages to critically injure the albino Hyper Gyaos and destroy the flock, but gets roughed up enough to put her out of commission.[[/labelnote]]
** Godzilla Junior with help from Princess Celestia and Luna vs. several hundred Super and normal Gyaos [[labelnote:Result]] Godzilla Junior just barely manages to kill all but a few of the gyaos and drives off the others before collapsing from exhaustion.[[/labelnote]]
** Irys, Gigan, and Megalon vs. Grand King Ghidorah [[labelnote:Result]] Grand King Ghidorah pummels the trio, though they do manage to get one good hit on him. He calls off the fight by granting Irys her wish but it's left ambiguous if this is due to his injury or boredom.[[/labelnote]]
** Pre-Amnesia Monster X vs. Grand King Ghidorah in the past [[labelnote:Result]]Monster X hangs in there for a time but he's hopelessly outclassed. This changes when he transforms into Kaizer Ghidorah, evening the odds. After a brutal fight where the two beat each other to near death, Kaizer Ghidorah tears one of Grand King's heads off.[[/labelnote]]
** Monster X with assistance from Aria Blaze vs. Enjin [[labelnote:Result]] Enjin begins to overpower Monster X, not helped by the Kaizer Ghidorah's personality attempting to hijack X's mind. A powered-up Aria launches an internal attack on Enjin and magically enhances X enough he can mentally overpower Kaizer. Monster X then tears out Enjin's core and frees Aria, disintegrating Enjin.[[/labelnote]]
* ''Fanfic/WithThisRing'': Swamp Thing and Arcane in ''Binding 18''.
* ''Fanfic/ChildOfTheStorm'':
** When HYDRA unleashes a zombified kraken on New York, Loki eventually resorts to turning into an equally massive sea serpent in order to hold it still long enough for Thor to electrocute it.
** During the climax of the ''Bloody Hell'' arc in the sequel ''Ghosts of the Past'', Dresden carries out his [[Literature/DeadBeat canon]] feat of [[RaisingTheSteaks reanimating Sue the T. rex]] in order to level the playing field against the necromancers and their zombie armies. Selene counters this by [[ScaledUp transforming into a primordial dragon]]. To her credit, Sue lasts for a good while before Selene wins.
** The climax of the side story ''Unfinished Business'', among the rest of the fighting going on, sees ComicBook/ManThing [[spoiler: [[CompositeCharacter (Jason Woodrue mutated by Nimue)]]]] fighting ComicBook/SwampThing, both of them having been magically grown to massive heights.
* In ''Film/TheLordOfTheRings'' fic ''[[Fanfic/TheHeartTrilogy Heart of the Inferno]]'', the dragon Smaug battles Moria's Balrog at the peaks of the Misty Mountains.
* Crossover fanfiction ''Fanfic/HailToTheKingThuktunFlishithy'' features Godzilla and others {{Kaiju}} battling ''Evangelion'''s Angels.
* ''Fanfic/HellsisterTrilogy'': In "The Apokolips Agenda" arc, ComicBook/TheSpectre fights -- and crushes -- Trigon. The former is the embodiment of the God's Wrath, the latter is a literal king demon, and both of them are mountain-sized.
* Downplayed example in ''Fanfic/ABoyAGirlAndADogTheLeithianScript'' when Huan -- a wolfhound bigger than a horse -- and Carcharoth -- a wolf bigger than an ox -- fight to the mutual death.
* ''WebVideo/JurassicWhatIf'': During Episode 4, the ''Spinosaurus'' battles the ''Indominus rex'', and later it battles Rexy.
* ''Fanfic/JWITCHSeries'': The chapter "Big Trouble, Bigger Jade" features a fight between Jade (who's been grown to about fifty feet by a growth spell GoneHorriblyRight) and Gargoyle (a magical stone creature of roughly the same size). With some help from [[DishingOutDirt Cornelia]], Jade eventually wins.
* ''Fanfic/SuperRWBYSisters'':
** The final battle of Super RWBY Sisters [[spoiler: involves Bowser getting gigantic through magic, while the Mario Bros, Peach and Team RWBY get turned gigantic through the use of several Mega Mushrooms. After which a brawl the behemoths ensues, ending with the heroes beating Bowser in the fight.]]
** The Goomba Squad fights an actual [[VideoGame/FinalFantasyVII Behemoth]] at Bowser's Castle in RWBY: Superstar Saga plus Bowser's Minions. If it weren't for the Koopalings backing them up, they would have lost, plus becoming the Behemoth's dinner.
** In RWBY Partners in Time a Shroobified mutated Behemoth started to fight the heroes after [[spoiler: eating Dark Weiss alive]], but [[Manga/AkameGaKill Esdeath]] quickly dispatched it.
** Two Behemoths showed up in RWBY: Bowser's Inside Story. A Fawfulized Behemoth shows up right after Esdeath frees Sephiroth from his petrified prison, much to Weiss's and the Winter Ops' dismay. And then [[Franchise/KingdomHearts another Behemoth]] shows up to help aid [[spoiler: Heartless Bowser]], where it would attack Ganondorf and Sephiroth, the former proceeding to fight it and the latter letting Ganon take care of it and only stepping in if he needed to.
* ''Fanfic/JackieChanAdventuresOlympianJourney'': During the climax of the Poseidon arc, [[spoiler: the Six-Eared Macaque (amped by Poseidon's powers) and the real Sun Wukong (using the Armor of the Eight Immortals) both grow to massive sizes during their clash in London.]]
* A quit common occurance in ''Fanfic/TheNewAgeOfMonsters''. Kaijus that hate humans constantly clash with kaiju that want to protect humans, [[Film/PacificRim Jaegers]] or [[Anime/NeonGenesisEvangelion [=EVAs=]]]. The only fights that are ''not'' this are those involving the [[{{Anime/Symphogear}} Symphogears]].
[[/folder]]

[[folder:Film — Animated]]
* The ending of ''WesternAnimation/{{Ark}}'' reveals that there are actually ''two'' Arks on Alcyeon, the Ark of York being hijacked by the evil vizier, Baramanda, while there's a second Golden Ark hidden underground. The film's ending have Amarinth piloting the second Ark and battling Baramanda in order to save the remaining population of Alcyeon.
* The climactic battle from ''Anime/KingsglaiveFinalFantasyXV'' features gigantic statues coming to life and battling it out with demons just as enormous in the middle of a city, all of that while the protagonist and the villain fight on top of the larger combatants, jumping from one of them to another. It's about about as epic as it gets.
* In ''WesternAnimation/HowToTrainYourDragon2'', two Bewilderbeasts, gigantic ice-breathing dragons, fight each other, one protecting the Glacial Sanctuary from the other one which serves the BigBad, Drago Bludvist.
* ''WesternAnimation/TheLandBeforeTime'' has the battle between [[MamaBear Littlefoot's mother]] (an ''Apatosaurus'') and [[PredatorsAreMean Sharptooth]] (a ''[[TerrifyingTyrannosaur Tyrannosaurus rex]]''), two of the biggest and most powerful dinosaurs in the franchise.
* ''WesternAnimation/{{Rumble}}'': The movie takes place in a world where {{kaiju}} not only exist, but have undertaken epic fights since prehistory, witnessed all the while by awed humans. In modern times, this has evolved into a kind of ProfessionalWrestling circuit for giant monsters.
* ''WesternAnimation/TheSeaBeast'': The Red Bluster, the eponymous [[SeaMonster sea beast]], gets in a fight with a GiantEnemyCrab that tries to eat Jacob and Maisie.
* In [[WhatCouldHaveBeen an earlier version]] of ''WesternAnimation/TurningRed'', Mei was going to turn into a kaiju-sized red panda equaling her mother and battle her all over Toronto.
[[/folder]]

[[folder:Film — Live-Action]]
* The TropeMaker is probably ''Film/TheLostWorld'' (1925), which had a fight scene between an ''Allosaurus'' and a ''Brontosaurus''. Stop motion effects were provided by Willis O'Brien, who also did...
* Film/KingKong fights giant monsters in every installment:
** ''Film/KingKong1933'': King Kong fighting a ''[[TerrifyingTyrannosaur Tyrannosaurus rex]]''. This might be the TropeCodifier for modern giant monster fights in movies, and seems to have invented the PrimateVersusReptile variant. He also fights a giant plesiosaur and a ''Pteranodon'' in less iconic -- but still pretty cool -- scenes.
** ''Film/TheSonOfKong'': Kong's son fights a "dragon" (which resembles a nothosaur) and a giant cave bear.
** ''Film/KingKong1976'': King Kong fights giant snake.
** ''Film/KingKong2005'': King Kong fights no less than three ''Vastatosaurus rex'', [[TRexpy a fictive descendant]] of the ''Tyrannosaurus rex'', as well as a flock of bat-like ''Terapusmordax''.
* Parodied in ''[[Film/{{Crank}} Crank: High Voltage]]''. There is a fight between Chev Chelios and Johnny Vang that suddenly turns into a ''Film/KingKongVsGodzilla'' battle. Most of it is a hallucination, though.
* All the ''Film/{{Gamera}}'' movies with the exception of [[Film/GiantMonsterGamera the first movie]].
** ''Film/GameraVsBarugon'' (1966): Gamera battles a crocodile-chameleon monster that breathes freezing mist from its tongue and shoots a rainbow beam from its back.
** ''Film/GameraVsGyaos'' (1967): Gamera battles a giant vampire bat-pterodactyl monster.

** ''Film/GameraTheBrave'' (2006): Gamera's ''son'' fights a sea monster named Zedus after the original one performs a HeroicSacrifice fending off Gyaos.
* The ''Franchise/{{Godzilla}}'' franchise gets a category for itself (in fact, there's only [[Film/Godzilla1954 four]] [[Film/TheReturnOfGodzilla live-action]] [[Film/ShinGodzilla Godzilla]] [[Film/GodzillaMinusOne movies]], [[Film/Godzilla1998 not counting the 1998 remake]] and out of over thirty total, where he doesn't fight another monster):
** ''Film/GodzillaRaidsAgain'' (1955) is against Anguirus (his first enemy, and later frequent ally).
** ''Film/KingKongVsGodzilla'' (1962): The point of the movie is to get [[UltimateShowdownOfUltimateDestiny King Kong to fight Godzilla]]. Kong also fights a giant octopus before squaring off against Godzilla.
** ''Film/MothraVsGodzilla'' (1964) has Godzilla fight ''three'' Mothras: the imago and two larvae.
** ''Film/GhidorahTheThreeHeadedMonster'' (1964) sees Godzilla fight Rodan until the focus switches to the title monster. Mothra also participates.
** ''Film/InvasionOfAstroMonster'' (1965) has Godzilla and Rodan battle Ghidorah again.
** ''Film/EbirahHorrorOfTheDeep'' (1966) pits Godzilla against...well, you know. [[MyFriendsAndZoidberg Oh, and a giant condor.]]

** ''Film/GodzillaVsMechagodzilla'' (1974) also features King Caesar in the mix.
** ''Film/TerrorOfMechagodzilla'' (1975) actually primarily sees Godzilla fighting Titanosaurus, though Mechagodzilla returns in the climax.
** ''Film/GodzillaVsBiollante'' (1989) pits Godzilla against Biollante's rose form in a lake, and then her ''absolutely gigantic'' second form outside a city.

** ''Film/GodzillaVsMechagodzillaII'' (1993) where he also battles Rodan, and the two of them both go against Mechagodzilla at the end.
** ''Film/GodzillaVsSpaceGodzilla'' (1994) is a three-way battle between Godzilla, Spacegodzilla, and Mogeura.
** ''Film/GodzillaVsDestoroyah'' (1995). Made even more titanic by the fact that Godzilla is going through nuclear meltdown and grieving the death of Godzilla Jr. at the same time
** ''Film/Godzilla2000'' (1999) has Godzilla fight Orga.
** ''Film/GodzillaVsMegaguirus'' (2000) pits Godzilla against the title opponent, a huge prehistoric dragonfly as well as a swarm of her smaller (but still huge) Meganula minions.
** ''Film/GodzillaMothraKingGhidorahGiantMonstersAllOutAttack'' (2001) also sees Baragon appear as one of Godzilla's enemies.
** ''Film/GodzillaAgainstMechagodzilla'' (2002) is pretty self-explanatory, except that this Mechagodzilla is constructed from the bones of the original 1954 Godzilla.
** ''Film/GodzillaTokyoSOS'' (2003) has Mechagodzilla and Mothra fight Godzilla.
** ''Film/GodzillaFinalWars'' (2004) features almost every monster from the previous films as well as a CurbStompBattle against the '98 Godzilla.
* The main thing about the Film/MonsterVerse, with modern state-of-the-art special effects and cinematography:
** ''Film/{{Godzilla|2014}}'' introduces the Mutos to Godzilla's RoguesGallery.
** ''[[Film/GodzillaKingOfTheMonsters2019 Godzilla: King of the Monsters]]'' has numerous fights: Rodan vs. Ghidorah, Mothra vs. Ghidorah, Mothra vs. Rodan, and ''three'' fights between Godzilla and Ghidorah.
** ''Film/KongSkullIsland'' has King Kong fighting against giant reptilian monsters called "Skullcrawlers", and at one point also fights a GiantSquid.
** ''Film/GodzillaVsKong'' is self-explanatory. It has the biggest version of Kong ever seen (he was only maybe a ''teen'' in ''Kong: Skull Island''), dwarfing the [[Film/KingKongVsGodzilla Japanese version]] by a large margin. The film features two major battles with the pair, as well as Kong fighting a pair of snake-like kaiju called Warbats, a swarm of bat-like Hellhawks, and [[spoiler:a "[[CurbStompBattle battle]]" between Mechagodzilla and a giant Skullcrawler, Godzilla vs. Mechagodzilla, and ''both'' Kong and Godzilla against Mechagodzilla in the very FinalBattle.]]
** ''Film/GodzillaXKongTheNewEmpire'' possibly contains the most monster fights of any film in the entire Godzilla or King Kong franchise. It starts with a BatmanColdOpen with Kong fending off a pack of hyena-like Wart Dogs, and Godzilla fighting Scylla, and over the course of the movie, Godzilla fights the serpent-like Tiamat, Kong fights several of [[BigBad Skar King]]'s ape minions, an eel-like lake monster, and Skar King himself, before he's defeated by Skar King's muscle, an ice reptile known as Shimo. The Kong and Godzilla have another rematch, before [[spoiler:Mothra breaks up the conflict, and all three monsters, along with the ape child Suko, fight against Skar King, his army, and Shimo in the climactic battle.]]
* Many of Creator/RayHarryhausen's films featured monster battles:
** ''Film/TheAnimalWorld'' (1956): Two ''ceratosaurus'' fight, both of them ultimately falling off a cliff.
** ''Film/TwentyMillionMilesToEarth'' (1957): Ymir (giant alien)/elephant battle.
** ''Film/The7thVoyageOfSinbad'' (1958) -- Cyclops/dragon battle.

* ''Film/TheHobbitAnUnexpectedJourney'' features a scene where mountain-sized stone-giants fight each other, unaware of the adventuring party below them. The part of the book the scene is based on describes it in much less detail.
-->'''Balin:''' This is no thunderstorm -- it's a thunder-''battle!''
* ''Franchise/JurassicPark'':
** ''Film/JurassicParkIII'' (2001): a ''Tyrannosaurus rex'' [[SpinosaurusVersusTRex fights a]] ''[[http://en.wikipedia.org/wiki/Spinosaurus Spinosaurus]]''.
** In ''Film/JurassicWorld'', the climactic FinalBattle involves [[spoiler: ''Tyrannosaurus'' and ''Velociraptor'' vs ''Indominus rex'' (a dinosaur that was artificially-designed), plus ''Mosasaurus'' provides a finishing move.]]
** In ''Film/JurassicWorldFallenKingdom'', A Carnotaurus fights a Sinoceratops
** In ''Film/JurassicWorldBattleAtBigRock'', an Allosaurus fights a Nasutoceratops.
** ''Film/JurassicWorldDominion'' has the ''Tyrannosaurus'' battling a ''Giganotosaurus'' with a ''Therizinosaurus'' joining the fight partway in.

* ''Film/OneMillionBC'' had an infamous fight scene between a pair of {{slurpasaur}}s. Stock footage of the scene was used in a lot of B movies throughout the '50s and '60s -- you can find a full list over on the {{slurpasaur}} page. If you've seen much ''Series/MysteryScienceTheater3000'', though, you've probably seen this fight scene several times.

** Halfway through the film a vengeful warrior god turns himself to a kaiju-sized monster to battle an ancient guardian, a giant albino ape (so a King Kong with white fur, if you prefer).

* The ''Snake'' trilogy, where the first is a Chinese ForeignRemake of ''Film/{{Anaconda}}'' while the sequels took on a more distinct identity of their own, adds an increasing amount of prehistoric monsters as the movies goes on. The third movie in particular have the film's bunch of adventurers trapped in a jungle full of [[TerrifyingTyrannosaur T. rexes]] before finally meeting [[TheGreatSerpent the titular snake]], which turns out large enough to battle and devour half a dozen T-Rexes all at once.
* Several non-Godzilla Creator/{{Toho}} films prove that you don't need your most famous monster in order to have some epic fights:
** ''Film/FrankensteinConquersTheWorld'' (1965) pits a giant version of FrankensteinsMonster against the subterranean saurian Baragon (who would as mentioned above later go on to fight an evil Godzilla). The alternate ending also has him against the giant octopus from ''King Kong vs. Godzilla''.
** ''Film/WarOfTheGargantuas'' (1966) serves as a sequel to the above and features two Frankensteinian monsters, Sanda the brown gargantua who is a good guy who likes and protects humans and its kind-of spawn Gaira the green gargantua who is violent, savage and [[ImAHumanitarian eats people]]. Naturally, they end up fighting. Gaira also briefly fights a giant octopus at the beginning.
** ''Film/KingKongEscapes'' (1967), where Kong fights a robot replica of himself, the dinosaur Gorosaurus, and a sea serpent.
** ''Film/SpaceAmoeba'' (1970): The climax of the movies features a battle between a giant turtle called Kamoebas and a monster crab named Ganimes when the titular alien loses control of both monsters.

** The ''Film/RebirthOfMothra'' trilogy (1996-1998) has Mothra Leo fight a terrifying opponent each film: the devastating Death Ghidorah, the aquatic Dagahra, and finally King Ghidorah himself.
* Capping the list with a really ''odd'' example; ''Film/WarGod'' has a trio of Martians invading earth with their enlarging rays, super-sizing themselves into skyscraper-sized behemoths to crush earth's cities, and humanity's faith managed to summon a savior - UsefulNotes/GuanYu, kaiju-sized!
[[/folder]]

[[folder:Literature]]
* The ''Literature/DreamPark'' novel ''The Barsoom Project'' features two examples: the War-Bots simulator scenario in which two opposing diplomats face off in control of HumongousMecha, and the finale of the Fimbulwinter Game, in which the BigBad in the form of a Terichik battles the Inuit hunter-god Torngarsoak.
* In the finale of ''Literature/TheBrothersLionheart'', Jonathan vanquishes the dragon Katla by rolling a boulder on her that pushes her into a waterfall. Karm, the 'lindworm' that inhabits the waterfall attacks Katla, and Jonathan and Skorpan watch in awe as the two monsters [[MutualKill fight each other to death]].
* In ''Literature/JourneyToTheCenterOfTheEarth'', the explorers are caught in the middle of a fight between an icthyosaur and a plesiosaur.
* ''Literature/JourneyToTheWest'': Sun Wukong's ability to shapeshift lets him also change sizes, which grants him a Kaiju size form, which he uses to find the other {{Sizeshifter}}s with giant forms, such as Nezha, Erlang, or the Bull Demon King.
* In ''Literature/TheKaijuPreservationSociety'', while traveling from Honda Base to Tanaka Base in the ''Shobijin'' airship, the new arrivals to Kaiju Earth become unintentional witnesses to a battle between two kaijus, one of which they know and which should've been picked up on the ''Shobijin'' radar due to the tracker placed on it. The airship has to rapidly gain altitude in order to avoid becoming collateral damage. [[spoiler:Later on, the losing kaiju ends up having its biological nuclear reactor explode, which isn't that uncommon when two kaiju fight.]]
* In ''Prehistoria: The Raptor's Tail'': A battle breaks out between a ''Deinocheirus'' and ''Therizinosaurus'' with the protagonist caught in the middle. Seen from the perspective of a wolf-sized raptor trapped between them, it results in the clashing megafauna looking like enormous kaiju.
* In ''Ragnarök'', the first sequel to ''Literature/{{Valhalla}}'', an internet sequence features a fight between a colossal crab with a mountain for a shell and a gargantuan arctic fox. The battle wrecks half the Nikkei site, throwing the world into economic turmoil for the rest of the book.
* The climax of ''Literature/ReadyPlayerOne'' features the main characters turning into Series/{{Ultraman}} and [=Mecha=]Franchise/{{godzilla}} to battle each other. In [[Film/ReadyPlayerOne2018 the movie adaptation]], Ultraman is switched out for WesternAnimation/TheIronGiant.

She grabs Iblis (which resembles a giant demon) with one arm and crushes it with brute strength, then obliterates Poseidon (which resembles a giant squid) with a simultaneous barrage from all of her cannons.
* In ''Literature/TheVoyageOfStBrendan'', St. Brendan the Navigator and his crew are pursued by a giant fish that wants to swallow them. Upon their prayers, another nondescript "great monster" appears that fights the first monster and kills it.

[[/folder]]

[[folder:Live-Action TV]]
* ''Series/TheBookOfBobaFett'' has Boba Fett's rancor being used by him to take down the Scorpenek droids of the Pyke Syndicate, which are giant robots that are otherwise immune to blaster fire because of their shields.
* In the {{mockumentary}} TV film ''Film/DragonsAFantasyMadeReal'', there is a fight between a ''Tyrannosaurus rex'' and a Prehistoric Dragon [[spoiler: and his mother]].
* Serves as the climax of nearly every ''Franchise/SuperSentai'' episode starting with ''Series/BattleFeverJ'' (and by extension, every ''Franchise/PowerRangers'' episode), where the MonsterOfTheWeek pulls a MakeMyMonsterGrow and the heroes counter by summoning their HumongousMecha. However, the concept for a climatic battle between giant opponents originated from Toei's ''[[Series/SpiderManJapan Spider-Man]]''[[note]]yes, ''that'' ComicBook/SpiderMan[[/note]] live action series.
* The ''Franchise/UltraSeries'' was built off the idea of bringing this trope to the small screen. The franchise started as a MonsterOfTheWeek [[Series/UltraQ mystery/horror series]] where the Monster was more often than not gigantic, but really took off when ''Series/{{Ultraman}}'' added a SuperHero to transform and battle said kaiju one-on-one.
** Occasionally, the monsters get to battle each other as well. In fact, ''Series/UltraGalaxyMegaMonsterBattle'' features ''only'' battles between the various {{kaiju}} from the franchise's history in a {{Mons}} style.
** ''Series/{{Ultraman}}'' and its many sequels, spinoffs, and remakes ended up spawning the ''Kyodai Hero'' genre, which is focused around superheroes like Series/ZoneFighter and Series/{{Spectreman}} who turn giant-sized to battle kaiju.
* The TVB adaptations of ''Series/JourneyToTheWest1996'' have one in the start of each season, both instances involving a KingKongCopy whose weakness is [[AttackTheTail in their tails]].

** Season 2 introduces the Six Ear Macaque, another behemoth-sized simian monster (not unlike Wukong in the previous season) going on yet another rampage, until Wukong decide to enlarge himself to battle the Macaque.
* The Creator/{{Toho}} drama series ''He of the Sun'' features a {{crossover}} battle between the man-eating giant Gaira from Toho's own ''Film/WarOfTheGargantuas'' and Kiyla, an insect-like ''Series/{{Ultraman}}'' monster with literal GlowingEyesOfDoom.
* ''Series/{{Arrowverse}}''
** The Season 3 finale of ''Series/LegendsOfTomorrow'' sees the Season's BigBad Mallus (a demon who already towers over most of the human characters) facing off against the Legends who used the six [[{{MacGuffin}} Zambezi Totems]] to perform a FusionDance into a building-sized, fully-sentient Beebo (a stuffed toy that was itself also a Mcguffin in an earlier episode).
** A Season 1 episode has Ray Palmer [[ReversePolarity reverse the polarity]] of his shrinking Atom suit to become a giant in order to fight the massive Leviathan robot sent by Vandal Savage to destroy the rebels.
** One of the episodes of ''Series/TheFlash2014'' Season 5 features KillerGorilla Grodd (recurring adversary of the heroes) versus King Shark (who just performed a HeelFaceTurn).
* ''Series/PrehistoricPlanet'':

** In the second episode, the giant sauropod ''Dreadnoughtus'' gather in large numbers in a desert to compete for mates. Two males engage in a violent fight, standing on their hind legs while trying to push each other to the ground, delivering massive stabs with their thumb spikes and brutal bites with their rake-like teeth. The loser ultimately falls to the ground and is unable to get up due to its massive weight, eventually ending up dead.
** In the third episode, a female ''Quetzalcoatlus'' gets in a fight with another female that attempts to destroy her nest.
* ''Series/MonarchLegacyOfMonsters'':
** The prologue of the first episode has Bill Randa, during the events of ''Film/KongSkullIsland'', accidentally instigating a battle between the spider-like Mother-Longlegs, and the crab-like Mantleclaw, which ends with both gargantuan arthropods plunging into the ocean.
** In the Season 1 finale, Godzilla battles the Ion Dragon. The latter, while still a {{kaiju}}, is much smaller than the former, and it's a very one-sided battle, as Godzilla tears apart the Ion Dragon immediately.
[[/folder]]

[[folder:Tabletop Games]]
With tabletop games, creative players can homebrew their own giant monster battles using mechanics the game systems already have in place. The entries listed here have the concept as a central part of their design.
* ''TabletopGame/BattleTech'' (1984): Tactical wargame centered on giant piloted robots (or ''mechs''). Had a focus on team tactics, ie groups of mechs fighting each other. Spawned the Franchise/BattleTechExpandedUniverse franchise.
* In the ''{{TabletopGame/Greyhawk}}'' setting module [=WG7=], ''Castle Greyhawk'', a battle between an Apparatus of Kwalish and an iron golem piloted by an orc takes place on level 5. It's an AffectionateParody of FASA's ''TabletopGame/BattleTech'' game (the orc is even named "Fahzah").
* ''TabletopGame/KingOfTokyo'' is all about kaiju battling each other.
* ''TabletopGame/MagicTheGathering'': [[https://gatherer.wizards.com/pages/Card/Details.aspx?multiverseid=479631 Clash of Titans]] shows two colossal monsters prepare to fight as some humans look on.
* ''Mecha vs. Kaiju'': See if you can guess what the two main classes of Behemoth are. Occasionally you get inter-kaiju battles, who's proven largely bulletproof but is defeatable by other kaiju, which hate it passionately for no particularly clear reason.
* ''TabletopGame/{{Monsterpocalypse}}'' has this as its main premises, with every kaiju stereotype duking it out with one another. From giant [[RentAZilla dinosaurs]], [[KingKongCopy apes]] and {{Super Robot}}s, to ravenous aliens, [[AlienInvasion Martian]] [[TripodTerror tripods]] and {{Eldritch Abomination}}s.
* ''TabletopGame/{{Pathfinder}}'' has a number of monsters of the {{kaiju}} type, most of them stand-ins for Toho characters, and their fluff text describes their long history of fighting each other. That said, featuring a giant monster battle in an actual campaign would be very difficult to make interesting for the players.
* ''TabletopGame/{{Warhammer 40000}}'' which has has several faction who have massive mechs called Titans. Tyranids possess kaiju sized bio-titans, and Necrons have a couple of bad-tempered flying pyramids, one of them serving as the cage for the furious shard of an EldritchAbomination. Initially, these were restricted to the mass-combat [[GaidenGame/Specialist Game]] ''Epic 40,000'', but later editions added the smaller versions of these to the main game.
* ''TabletopGame/YuGiOh'': This is the Kaiju archetype's central gimmick. They can be Special Summoned to the opponent's field by tributing one of their monsters, and Special Summoned to the owner's field if the opponent controls a Kaiju. The default result is two behemoths taking over whatever battle was happening before to fight each other.
[[/folder]]

[[folder:Toys]]
* ''Toys/{{Bionicle}}'': In the final battle between Mata Nui and Makuta Teridax, both of them are inhabiting enormous, multi-million-foot-tall robots.
* While the ''Franchise/{{Transformers}}'' are fairly huge, the battles that fit the trope even for a Cybertronian's relative size are those between [[CombiningMecha Combiners]] and those between the Metrotitans of each faction such as the Autobot [[http://tfwiki.net/wiki/Metroplex_(G1) Metroplex]] and the Decepticon [[http://tfwiki.net/wiki/Trypticon_(G1) Trypticon]].
[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/Bayonetta2'', both Bayonetta and the Masked Lumen summon giant demons and angels that fight in the background ''while they themselves are battling''.
** In ''VideoGame/Bayonetta3'', there are several of these...and you ''are'' the behemoth.
* The boss of world 10 in ''VideoGame/CopyKitty'' is either a mech in the size of a fortress, or an enormous SpiderTank. Depending on which character you use, once you beat your respective giant robots, you get to ride it and destroy the other.
* ''[[VideoGame/ExtrapowerStarResistance EXTRAPOWER Star Resistance]]'': Occurs in the background of Stage 4. As the player fights through the capital city, a Stone Mack begins stomping through the background, only half its body able to fit on screen at a time, [[MookMaker releasing Clay Kids]] each time it returns. A little after, Metal Giga shows up, as large as Stone Mack, grappling it until it explosively sends its head flying.
* In ''VideoGame/DinoRex'', you control gigantic dinosaurs fiercely battling each other as part of a man's quest to become the ruler of the ancient world.
* In ''VideoGame/Fallout4'', you may come across with Behemoth, a type of gigantic Super Mutant. You can shove a Big Boy MIRV onto it, chip him bit by bit with Minigun, or better yet: ask [[BloodKnight Strong]], our resident Super Mutant companion to duke it out with those Behemoths. If you happen to find a Deathclaw, you can pacify them and bring them to the Behemoths. And if that wasn't huge enough: how about pacifying a ''Mirelurk Queen'' to [[ThereIsNoKillLikeOverkill deal with a Behemoth]]?
** If you choose to help out the Brotherhood of Steel in the finale, you get a Super Mutant Behemoth versus [[spoiler:the Liberty Prime Mk.II]]. [[CurbStompBattle The "fight" lasts about four seconds.]]
* ''VideoGame/FateGrandOrder'': The ClimaxBoss of the first Lostbelt is a mountain-sized mammoth ridden by/fused with Ivan the Terrible. The player is given control of Avicebron's Noble Phantasm, Golem Keter Malkuth, in order to be able to rival Ivan's size and power. The resulting clash terrorizes the inhabitants of the Lostbelt, who genuinely believe this to be a duel between gods.
* On one memorable location on Gran Pulse in ''VideoGame/FinalFantasyXIII'' (2009), you encounter a behemoth (a huge and nasty monster type) and a giant dog-like monster fighting each other. The two of them block the passage to your destination but are so consumed by their fight that you can sneak past them with a bit of luck. If they do spot you, it results in a MeleeATrois where you can play one of them against the other to make it slightly easier.
* ''VideoGame/FreedomPlanet2'' is not afraid to have the player fight giant robots, but there is one situation where this trope is utilized. [[spoiler:Aaa allows the team to commandeer the BFF-2000 - a boss from a previous stage - after the rest of his robotic "buddies" were corrupted by Syntax's [[ComputerVirus Code Black]] and hijacked by Serpentine.]]
* ''VideoGame/GodOfWarIII'' (2010) opens up with battle between the Titan Gaia and Poseidon's OneWingedAngel form.
* ''[[VideoGame/KaijuCombat Colossal Kaiju Combat]]'': it's right there in the title.
* Both ''VideoGame/MarioAndLuigiBowsersInsideStory'' and ''VideoGame/MarioAndLuigiDreamTeam'' have playable segments where the player character grows giant in order to fight a giant opponent.

* Turf Wars between monsters in the same area area have become a part of the ''VideoGame/MonsterHunter'' series since ''VideoGame/MonsterHunterWorld''. When specific monsters meet up, they'll trigger a special fight sequence between them, which can deal major damage to the parties involved. ''VideoGame/MonsterHunterRise'' also allows the player to ride on monsters after stunning them, and then have them attack other monsters in the area.
* In ''[[VideoGame/GanbareGoemon Mystical Ninja: Starring Goemon]]'' you pilot the Humongous #Mecha IMPACT!! and combat it through a few evil super villain base levels and at the end of them you fight a huge boss, roughly the same size.
* While the ''Franchise/{{Pokemon}}'' series has had [[OlympusMons Legendary Pokémon]] duke it out from time to time, a major element of ''VideoGame/PokemonSwordAndShield'' is the Dynamax phenomenon which temporarily turns otherwise-normal Pokémon giant in battle. Pokémon Gyms in the Galar region are built on areas where the phenomenom can be harnessed to have giant trained Pokémon fights in front of an audience.
* ''VideoGame/PowerRangersLightspeedRescue'' have a few select bosses (Loki, Darebolico, Olympius, and Queen Bansheera) who, upon their initial defeat, then turns kaiju-sized, necessitating you to summon the Train Megazord to continue the fight. In such instances however the stage shifts to a PhantomZone so as to avoid damaging civilian structures and prevent collateral damage.
* ''VideoGame/PrimalRage'' was a FightingGame set AfterTheEnd, when the resurrected gods of dinosaurs and [[KingKongCopy giant apes]] battle for control over what remains.
* ''VideoGame/PrincessPeachShowtime'' has this in Mighty Peach's second play where the Professor and the freed scientists use their programming to make her giant in order to fight the equally-large alien mech at the end…except that this is a stage play, so she's actually fighting on a {{Toku}}-style tiny set.
* In ''VideoGame/SuperMario3DWorld + VideoGame/BowsersFury'' the new ''Bowser's Fury'' quest has Mario becoming [[MegaNeko Giga Cat Mario]] in order to fight an equally giant Fury Bowser.
* One of the levels in ''VideoGame/SuperSmashBrosMelee'' has a giant Bowser fighting an equally giant Donkey Kong on skyscrapers, as an homage to ''Film/KingKongVsGodzilla''.
* ''Videogame/TechRomancer'' is a big love letter to multiple old HumongousMecha series(plus Series/{{Ultraman}}) as a FightingGame.
* ''VideoGame/{{Ultrakill}}'': [[spoiler:Level 7-4 features the 1000-THR "[[MeaningfulName Earthmover]]", a HumongousMecha that is essentially [[ColossusClimb the entire level]], while it's in the middle of a fight with ''another'' Earthmover across the horizon. How do they battle? By [[WaveMotionGun firing massive beams of electricity]] via the [[LightningGun weapons]] embedded into their arms.]]
* ''VideoGame/WarOfTheMonsters'' (2003) is a FightingGame where you can play as different kinds of {{Kaiju}}.
* Happens whenever a Knight clashes with another Knight or other large opponent in ''Videogame/WhiteKnightChronicles''. To get the full effect, switch to one of the other party members to get a ground view of your party's Knight fighting its equally large opponent (not recommended for tougher fights since the AI isn't that great).
* ''VideoGame/TheWonderful101'' (2013) has battles between HumongousMecha and bigger HumongousMecha.
* The opening cutscene of ''VideoGame/XenobladeChronicles1'' (2010) features a titanic clash between the god-like entities Mechonis and Bionis. They were so big that after said battle their still-standing corpses form the world that the game takes place on.
[[/folder]]

[[folder:Web Animation]]
* Episode 27 of ''WebVideo/SuperPowerBeatDown'' diverge from the usual superheroes fight to give us "Godzilla vs. Dragonzord". Happens at the harbor of a city and causes lots of collateral damage to the surrounding buildings.
* [[https://www.youtube.com/watch?v=hedUAqopPBg This animated video]] of the Bloop (shown as a giant whale) fighting another giant sea monster called El Gran Majá.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/{{Aurora}}'': Subverted. There are several sections which Red, the author, allegedly nicknamed "the kaiju fight." The first was in chapter 17, when Tynan's OneWingedAngel form fought the Void Dragon, [[spoiler: who of course isn't physically there and thus manifests through a human-sized avatar that remains powerful enough to issue a CurbStompBattle to the legendary storm god.]] The second is in chapter 18, when Tynan's OneWingedAngel form fights [[spoiler: Vash, who has slightly more difficulty doing so but has the advantage of not being an existential threat that prompts a universal EnemyMine, and is ALSO human-sized.]] And then the third one is in chapter 22, when Dainix [[spoiler: in his demon form]] goes up against some kind of fusion of cave crawlers. Both are larger than normal humans, neither are really large enough to call themselves kaijus.
* ''Webcomic/GirlGenius'': The fight (2012) between Franz Scortchmaw, the Bone Gnawer of the Heterodynes, and "Pretty Boy" (no name given, despite his gentledragonly manners). [[http://www.girlgeniusonline.com/comic.php?date=20121001 Rather low on the collateral damage for a monster fight, though.]]
** Lucrezia and one of her former stooges turn into Kaiju by using a Heterodyne fountain, fight it out, and cause so much noise that it awakens the Leviathan, which is the size of Albion and spews hordes of more Kaiju to attack them both.
* It doesn't last very long, but ''Webcomic/TheInexplicableAdventuresOfBob'' memorably gives us [[https://bobadventures.thecomicseries.com/comics/526 Unigar the Vast Unicorn vs. Molly's giant robot lion.]]
* ''Webcomic/GurralTheSmasher'': Each issue contains one or more giant monster fight, with the earlier issues focusing on Gurral's tenure as a gladiator for the Arena Lords, and later issues having him go AWOL and team up with Project Prometheus to protect the Earth from malicious kaiju.
[[/folder]]

[[folder:Western Animation]]
* An episode of ''WesternAnimation/AvatarTheLastAirbender'' has a fight between Appa the sky bison (a gigantic, six-legged flying creature) and a shirshu (an enormous aardvark-like monster with a venomous tongue).
* ParodiedTrope in ''WesternAnimation/CourageTheCowardlyDog'' episode "The Transplant", where Eustace is turned into a HalfHumanHybrid Kangaroo {{Kaiju}} after a transplant surgery GoneHorriblyWrong. Courage, in an attempt to rescue Muriel, undergoes a similar transplant to turn himself into a similar monster. The two initially battle it out conventionally in Paris, before the fight between them devolves into a painting competition, and later, Courage feeding Eustace a ton of giant croissants.
* ''WesternAnimation/{{Futurama}}'':
** "[[Recap/FuturamaS2E16AnthologyOfInterestI Anthology of Interest I]]": A giant Bender is attacking the city, so Professor Farnsworth enlarges Zoidberg to fight it.
--->'''Hermes:''' We're jerked! Nothing can stop a monster that big!\\
'''Prof. Farnsworth:''' Nothing except an even more equally big monster!

* Both ''WesternAnimation/GodzillaTheSeries'' and ''WesternAnimation/TheGodzillaPowerHour'': Godzilla versus MonsterOfTheWeek.
* Despite the number of [[AttackOfTheFiftyFootWhatever Mega-Mutes]] in ''WesternAnimation/KipoAndTheAgeOfWonderbeasts'', including the titular character once she learns how to shapeshift into a Mega-Jaguar, there are very few fights between Mega-Mutes in the series, [[spoiler: until the finale when Dr. Emilia reverse-engineers Kipo's genetic modifications to transform herself into a Mega-Walrus.]]
%%* ''WesternAnimation/TheLegendOfKorra'' has Unavaatu veres Spirit-Korra.
* One of Creator/TerryGilliam's ''Creator/MontyPython'' animations was about an invasion of killer cars that were defeated by atomically-mutated giant cats. Unfortunately the cats then ate the city.
* Lampshaded in the ''WesternAnimation/PhineasAndFerb'' episode Doof Dynasty. The medieval Chinese versions of the protagonists pilot a giant terracotta warrior into battle against Doofus Kahn's mecha dragon. Monogram sees the fight and remarks: "Man they would love this in Japan."
* In the ''WesternAnimation/PinkyAndTheBrain'' episode "Tokyo Grows", Brain attempts to take over Tokyo by disguising Pinky as the [[RentAZilla giant monster]] [[PunnyName Gollyzilla]], turning him into a giant with a reversed ShrinkRay, and then turning himself giant too and [[EngineeredHeroics saving the city by fighting Pinky]]. Hilarity ensues when the real Gollyzilla shows up and Brain fights him instead of Pinky.
* ''WesternAnimation/Primal2019'': One of the show's protagonists is a female ''Tyrannosaurus rex'' named Fang, who ends up fighting another PrehistoricMonster at least OnceAnEpisode. She fought other tyrannosaurs who [[MonstrousCannibalism ate her nestlings]], a giant snake, wooly mammoths, giant bats, a GiantSpider and a [[KingKongCopy monstrous ape-man]]. [[spoiler:The show's other protagonist, Spear the caveman, also gets turned into a giant and fights said ape-man after it seemingly kills Fang.]]
* ''WesternAnimation/StevenUniverse'':
** [[FusionDance Gem fusions]] are massive, ranging from "has to duck to fit through a door" to "the size of a building". Pit the two biggest ones against each other, and you [[Recap/StevenUniverseS3E1SuperWatermelonIsland get]] the Behemoth Battle that is Alexandrite versus Malachite, a fight that takes up nearly an episode, only [[ItMakesSenseInContext interrupted by a watermelon riot]].
** [[Recap/StevenUniverseS5E28ChangeYourMind "Change Your Mind"]] has two:
*** First off, [[spoiler:Blue and Yellow Diamond (who [[LargeAndInCharge aren't]] fusions)]] get into a fight when their views about [[spoiler:their long-lost younger sister [[WhiteSheep Pink Diamond]]]] get the better of them (one of them has had a HeelRealization, and it takes the fight for the other to have one too).
*** Then there's [[spoiler:the [[CombiningMecha Diamond Mecha]], piloted by White Diamond]] versus the ''enormous'' fusion [[spoiler:Obsidian, composed of Steven, Garnet, Amethyst and Pearl]]. [[spoiler:Obsidian, while much smaller than the Diamond Mecha, uses her {{BFS}} to cut off its hands and reach the head, where she screams into its eyes. The Crystal Gems are then able to climb inside to confront White after being defused.]]
** The SequelSeries ''WesternAnimation/StevenUniverseFuture'' has a climax where [[spoiler:Steven's stress and repressed mental issues lead to him transforming into a Godzilla-esque monster as large as a mountain. The Crystal Gems fuse into Alexandrite trying to restrain him, but [[CurbStompBattle are defeated instantly]]. The Cluster, taking the form of a giant arm, has somewhat more success, restraining the Steven-monster for several minutes.]] Finally, this trope is also {{defied}} by [[spoiler:Garnet, whom Yellow Diamond transforms into a giant: instead of fighting Steven, she gives him a CooldownHug that everyone else joins afterwards]].
* ''WesternAnimation/TheTransformers'': The [[CombiningMecha combiners]] tower over regular Transfomers, so the few times combiners get into fights count as this. However, Season 3 introduces Metroplex (who is part of Autobot City, a fortress scaled to Transformer-size) and Trypticon, who is created in the first few episodes when the Constructicons bring an actual human city to life and grant it a Tyrannosaurus Rex-like robot mode. Trypticon is so gigantic he is able to smash the original Autobot HQ to pieces, volcano and all.
* ''WesternAnimation/TheWackyAdventuresOfRonaldMcdonald'': The climax of the rare sixth and final video ''The Monster O'[=McDonaldland=] Loch'' has a battle occur between Simon (the titular StockNessMonster) and his robot double built by the video's villain Stiles.

* Most massive real world predators actually tend to avoid each other, or when there is a chance encounter prefer to use threat displays rather than simply duke it out, the obvious reason that it's too risky for both parties. Exceptions include:
** The battles to the death that occur when sperm whales prey on giant squid. Many whales carry the scars of these titanic fights.
** Occasions of predation between large carnivores and equally massive herbivores can also count in the minority of cases the predator isn't attacking a young or weakened prey item. An example of the fossil record would be conflicts between ''Tyrannosaurus'' and ''Triceratops'', with teeth and horn caused scars found on each other as proof of titanic battles.
** Even more interesting than the Sperm Whale/Giant Squid conflict would perhaps be the prehistoric encounters between ''Carcharodon megalodon'' and ''[[KrakenAndLeviathan Livyatan melvillei]]'' (the former a giant shark, the latter an older version of a sperm whale [[TookALevelInBadass with bigger teeth]]). There's little evidence they actually did battle with each other, but the fact that they were the two largest predators of their time and place and that they were roughly the same size would make for a very intriguing [[AwesomeButImpractical (while infrequent]]) scenario.
* Surprisingly this ''does'' happen from time to time with megafauna herbivores in greater degrees than with carnivores due a combination of factors ranging from higher population, having less danger of starving due to not needing to chase down their food, and HerbivoresAreFriendly being very much averted in real life with most species who aren't skittish being highly aggressive.
** [[https://roaring.earth/hippo-vs-rhino-rare-encounter-caught-on-camera/ Here's one example of a hippopotamus engaging in a fight with a few white rhinos]]. [[https://www.youtube.com/watch?v=5dYPHFhnqRA Here's another one where a hippo confronts a cape buffalo]].
** Male elephants during musth become highly territorial and aggressive, and often engage in battle, locking tusks and wrestling each other to submission.
** In the 1960s, electrical workers in Nebraska found the fossilized remains of two mammoths that had died while locked in combat. Their tusks had gotten tangled into one another, and it was likely they had fought over a mate, were unable to free themselves after getting stuck together, and ultimately died of exhaustion.
** Male elephant seals (the largest extant pinnipeds in the world, with some specimens in the range of 4 tons) will engage in brutal fights during the breeding season much like their namesakes. Since they lack legs, the majority of these fights consist of males body slamming and biting each other, and both will usually be CoveredInScars by the time one backs down or dies.
** If male sauropods fought to establish dominance for breeding rights like many modern herbivores, then clashes between members of the largest genuses like ''Argentinosaurus'', ''Alamosaurus'', and ''Sauroposeidon'' may have been the greatest example of this trope to ever occur in the real world.
