Behemoth Battle

Oh, no, there goes Tokyo...

Hermes: We're jerked! Nothing can stop a monster that big!
Prof. Farnsworth: Nothing except an even more equally big monster!

— Futurama, "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 Humongous Mecha are explicitly included. For battles between giant machines and biological creatures see Mech vs. Beast.

In no small degree builds on Rule of Cool and Cool Versus Awesome. See also Monster Mash. Primate Versus Reptile is an especially common variant, thanks to the iconic fight scene in King Kong (1933). Following Jurassic Park III (2001), the Spinosaurus Versus T. rex pairing also gained some popularity.

Any film set in a Lost World or Hollywood Prehistory setting will likely have such a scene.

Examples are generally sorted chronologically.

Examples:

Anime & Manga

• The Super Robot Genre, starting with Mazinger Z, is based on this with giant Humongous Mecha battling giant creatures or robots (depending on the work).
  • The movie "UFO Robo Grendizer, Getter Robo G, Great Mazinger: 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.
• Attack on Titan: 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 because said Titan is Eren Yeager himself, having come into his power as a Titan Shifter. Naturally, this leads to Titan duels and brawls as more Shifters are revealed that can completely wreck cities as if they're made of Styrofoam.
• The Big O: the eponymous Humongous Mecha battles other robots (called Megadeus) and a few giant monsters over the course of the series.
• A Certain Scientific Railgun: One such battle occurs at the end of the Dream Ranker Arc between Mikoto Misaka manipulating a giant skyscraper-sized iron-sand puppet against the Doppelganger of Ryoko Kuriba having created a similarly-sized puppet made of city debris.
• The Darkstalkers series is usually about human-sized monsters fighting each other, but the Night Warriors OVA adaptation decides to kick things up a notch in the final battle against the Big Bad, where a 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 Digimon Adventure: (2020), 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: 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.
• Fairy Tail
  • Several of these happen, usually whenever dragons are involved. Makarov's Titan form versus Acnologia at the end of the Sirius Island Arc, Atlas Flame versus Motherglare while Natsu and Future Rogue fight on their backs at the climax of the Grand Magic Games, and Igneel versus Acnologia near the end of the Tataros Arc.
  • Exaggerated in Fairy Tail: 100 Years Quest during the battle between Wood Dragon God Aldoron and Gajeel 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 be super-sized via magic to a comparable size explicitly compared to a mountain.
• In the final installment of the anime Godzilla trilogy, Godzilla: The Planet Eater there is one between Godzilla and his arch-enemy Ghidorah.
• While most dragon fights in Miss Kobayashi's Dragon Maid involve one or both parties 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 Pillar of Light so large that it was visible from space.
• 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 comparing it to Destroy All Monsters. And this is before they pull out their 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.
• Neon Genesis Evangelion: The eponymous EVA mechs are used by NERV to fight angels, which resemble weird giant aliens with no uniform appearance. the only thing that qualifies them as "angel" is that they have a "blood pattern blue", and halos.
• One Piece: 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.
• Pokémon: The Series: Several battles between 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 Taboo-Tattoo involved Touko and Izzy having fused together fighting Arya, who had fused with her sisters.
• Tengen Toppa Gurren Lagann starts off as a typical battle between Humongous Mecha who over the series escalates into galaxy sized ones.
• Yu-Gi-Oh!: Several battles between Egyptian God Cards, between the God Cards and the Great Leviathan, and between Zorc and Exodia, the Blue-Eyes Ultimate Dragon, and Horakhty.

Arts

• Carta Marina:
  • 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.

Comic Books

• One issue of the Buffy the Vampire Slayer Season Eight comics features a fight between Giant Dawn and Mecha-Dawn, while a delighted Xander watches.
• Near the climax of Earth X, a cohort of 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 Galactus is the size of the horizon.
• In The Goon, the title character is temporarily transformed into a giant gorilla so he can fight El Hombre Lagarto.
• 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 Lanfeust de Troy is fought between giant energy clones of Lanfeust and Thanos over Eckmül.
• Marvel's Shogun Warriors series is built around this trope. The titular trio of Humongous Mecha 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.

Documentaries

• Prehistoric Planet:
  • 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.
• Sea Monsters A Prehistoric Adventure: A 29-foot Tylosaurus finds himself fighting a larger individual of the same species. The skirmish concludes with the death of the smaller tylosaur.

  • Pre-Amnesia Monster X vs. Grand King Ghidorah in the past ^ResultMonster X hangs in there for a time but he's hopelessly outclassed.

• King Kong fights giant monsters in every installment:
  • King Kong (1933): King Kong fighting a Tyrannosaurus rex.

• One Million B.C. had an infamous fight scene between a pair of slurpasaurs. 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.

• The Snake trilogy, where the first is a Chinese Foreign Remake of 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 T. rexes before finally meeting the titular snake, which turns out large enough to battle and devour half a dozen T-Rexes all at once.

  • The Rebirth of Mothra trilogy (1996-1998) has Mothra Leo fight a terrifying opponent each film: the devastating Death Ghidorah, the aquatic Dagahra, and finally King Ghidorah himself.

Literature

• The Dream Park novel The Barsoom Project features two examples: the War-Bots simulator scenario in which two opposing diplomats face off in control of Humongous Mecha, and the finale of the Fimbulwinter Game, in which the Big Bad in the form of a Terichik battles the Inuit hunter-god Torngarsoak.

The airship has to rapidly gain altitude in order to avoid becoming collateral damage. 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 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 Ready Player One features the main characters turning into Ultraman and MechaGodzilla to battle each other. In the movie adaptation, Ultraman is switched out for The Iron Giant.
• The climax of The Yellow Fog has the giantess witch Arachne duking it out with Tilli-Willi the clockwork sentient mecha (who is assisted by Carfax the giant eagle).
• Undefeated Bahamut Chronicle has a very brief version of this. Rosa activates her Drag-Ride's Devil Machia Mode, which transforms it into a Humongous Mecha. 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 The Voyage of St. Brendan, 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. A few chapters later, under very similar circumstances, the voyagers witness a battle between a gryphon and another giant bird.

Live-Action TV

• The Book of Boba Fett 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 Dragons: A Fantasy Made Real, there is a fight between a Tyrannosaurus rex and a Prehistoric Dragon and his mother.
• Serves as the climax of nearly every Super Sentai episode starting with Battle Fever J (and by extension, every Power Rangers episode), where the Monster of the Week pulls a Make My Monster Grow and the heroes counter by summoning their Humongous Mecha. However, the concept for a climatic battle between giant opponents originated from Toei's Spider-Man^note yes, that Spider-Man live action series.
• The Ultra Series was built off the idea of bringing this trope to the small screen. The franchise started as a Monster of the Week mystery/horror series where the Monster was more often than not gigantic, but really took off when Ultraman added a Super Hero to transform and battle said kaiju one-on-one.
  • Occasionally, the monsters get to battle each other as well. In fact, Ultra Galaxy Mega Monster Battle features only battles between the various kaiju from the franchise's history in a Mons style.
  • Ultraman and its many sequels, spinoffs, and remakes ended up spawning the Kyodai Hero genre, which is focused around superheroes like Zone Fighter and Spectreman who turn giant-sized to battle kaiju.
• The TVB adaptations of Journey to the West (1996) have one in the start of each season, both instances involving a King Kong Copy whose weakness is in their tails.
  • Season 1 have Sun Wukong in the pilot, initially born as a rampaging giant monkey monster, fighting the Marshal Heavenly Mugwort whom had transformed into a giant, ending with Wukong's monster form having his tail severed regressing him into a child-like, monkey form.
  • 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 Toho drama series He of the Sun features a crossover battle between the man-eating giant Gaira from Toho's own War of the Gargantuas and Kiyla, an insect-like Ultraman monster with literal Glowing Eyes of Doom.
• Arrowverse
  • The Season 3 finale of Legends of Tomorrow sees the Season's Big Bad Mallus (a demon who already towers over most of the human characters) facing off against the Legends who used the six Zambezi Totems to perform a Fusion Dance 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 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 The Flash (2014) Season 5 features Killer Gorilla Grodd (recurring adversary of the heroes) versus King Shark (who just performed a Heel–Face Turn).
• Prehistoric Planet:
  • In the first episode, an old male Mosasaurus relaxing on a coral reef gets attacked by a younger male, and the two duke it out in a ferocious underwater battle.
  • 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.
• Monarch: Legacy of Monsters:
  • The prologue of the first episode has Bill Randa, during the events of Kong: Skull Island, 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.

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.

• 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 BattleTech Expanded Universe franchise.
• In the 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 Affectionate Parody of FASA's BattleTech game (the orc is even named "Fahzah").
• King of Tokyo is all about kaiju battling each other.
• Magic: The Gathering: 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.
• Monsterpocalypse has this as its main premises, with every kaiju stereotype duking it out with one another. From giant dinosaurs, apes and Super Robots, to ravenous aliens, Martian tripods and Eldritch Abominations.
• 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.
• Warhammer 40,000 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 Eldritch Abomination. Initially, these were restricted to the mass-combat [[Gaiden Game/Specialist Game]] Epic 40,000, but later editions added the smaller versions of these to the main game.
• Yu-Gi-Oh!: 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.

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 Transformers are fairly huge, the battles that fit the trope even for a Cybertronian's relative size are those between Combiners and those between the Metrotitans of each faction such as the Autobot Metroplex and the Decepticon Trypticon.

Video Games

• In Bayonetta 2, both Bayonetta and the Masked Lumen summon giant demons and angels that fight in the background while they themselves are battling.
  • In Bayonetta 3, there are several of these...and you are the behemoth.
• The boss of world 10 in Copy Kitty is either a mech in the size of a fortress, or an enormous Spider Tank. Depending on which character you use, once you beat your respective giant robots, you get to ride it and destroy the other.
• 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, 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 Dino Rex, you control gigantic dinosaurs fiercely battling each other as part of a man's quest to become the ruler of the ancient world.
• In Fallout 4, 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 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 deal with a Behemoth?
  • If you choose to help out the Brotherhood of Steel in the finale, you get a Super Mutant Behemoth versus the Liberty Prime Mk.II. The "fight" lasts about four seconds.
• Fate/Grand Order: The Climax Boss 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 Final Fantasy XIII (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 Mêlée à Trois where you can play one of them against the other to make it slightly easier.
• Freedom Planet 2 is not afraid to have the player fight giant robots, but there is one situation where this trope is utilized. 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 Code Black and hijacked by Serpentine.
• God of War III (2010) opens up with battle between the Titan Gaia and Poseidon's One-Winged Angel form.
• Colossal Kaiju Combat: it's right there in the title.
• Both Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Dream Team have playable segments where the player character grows giant in order to fight a giant opponent.
• Mass Effect 3: Epic battle in one cutscene features a giant thresher maw Kalros against Reaper Destroyer.
• MechWarrior (1989) are about giant mechs with human pilots battling it out, based on the BattleTech game. Received several sequels.
• In Metal Gear Solid 4: Guns of the Patriots (2008), there is an epic battle between the original Metal Gear Rex from the first Metal Gear Solid game, and a Metal Gear Ray unit.
• Turf Wars between monsters in the same area area have become a part of the Monster Hunter series since Monster Hunter: World. When specific monsters meet up, they'll trigger a special fight sequence between them, which can deal major damage to the parties involved. Monster Hunter: Rise also allows the player to ride on monsters after stunning them, and then have them attack other monsters in the area.
• In 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 Pokémon series has had Legendary Pokémon duke it out from time to time, a major element of Pokémon Sword and Shield 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.
• Power Rangers Lightspeed Rescue 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 Phantom Zone so as to avoid damaging civilian structures and prevent collateral damage.
• Primal Rage was a Fighting Game set After the End, when the resurrected gods of dinosaurs and giant apes battle for control over what remains.
• Princess Peach: Showtime! 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 Super Mario 3D World + Bowser's Fury the new Bowser's Fury quest has Mario becoming Giga Cat Mario in order to fight an equally giant Fury Bowser.
• One of the levels in Super Smash Bros. Melee has a giant Bowser fighting an equally giant Donkey Kong on skyscrapers, as an homage to King Kong vs. Godzilla.
• Tech Romancer is a big love letter to multiple old Humongous Mecha series(plus Ultraman) as a Fighting Game.
• ULTRAKILL: Level 7-4 features the 1000-THR "Earthmover", a Humongous Mecha that is essentially the entire level, while it's in the middle of a fight with another Earthmover across the horizon. How do they battle? By firing massive beams of electricity via the weapons embedded into their arms.
• War of the Monsters (2003) is a Fighting Game where you can play as different kinds of Kaiju.
• Happens whenever a Knight clashes with another Knight or other large opponent in White Knight Chronicles. 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).
• The Wonderful 101 (2013) has battles between Humongous Mecha and bigger Humongous Mecha.
• The opening cutscene of Xenoblade Chronicles 1 (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.

Web Animation

• Episode 27 of Super Power Beat Down 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.
• This animated video of the Bloop (shown as a giant whale) fighting another giant sea monster called El Gran Majá.

Webcomics

• Aurora: Subverted. There are several sections which Red, the author, allegedly nicknamed "the kaiju fight." The first was in chapter 17, when Tynan's One-Winged Angel form fought the Void Dragon, who of course isn't physically there and thus manifests through a human-sized avatar that remains powerful enough to issue a Curb-Stomp Battle to the legendary storm god. The second is in chapter 18, when Tynan's One-Winged Angel form fights Vash, who has slightly more difficulty doing so but has the advantage of not being an existential threat that prompts a universal Enemy Mine, and is ALSO human-sized. And then the third one is in chapter 22, when Dainix 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.
• Girl Genius: The fight (2012) between Franz Scortchmaw, the Bone Gnawer of the Heterodynes, and "Pretty Boy" (no name given, despite his gentledragonly manners). 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 The Inexplicable Adventures of Bob! memorably gives us Unigar the Vast Unicorn vs. Molly's giant robot lion.
• Gurral the Smasher: 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.

Western Animation

• An episode of Avatar: The Last Airbender 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).
• Parodied Trope in Courage the Cowardly Dog episode "The Transplant", where Eustace is turned into a Half-Human Hybrid Kangaroo Kaiju after a transplant surgery Gone Horribly Wrong. 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.
• Futurama:
  • "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!
  • "Benderama": Bender combines with his nanoreplicants to form one giant Bender to fight an alien giant.
• Both Godzilla: The Series and The Godzilla Power Hour: Godzilla versus Monster of the Week.
• Despite the number of Mega-Mutes in Kipo and the Age of Wonderbeasts, 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, until the finale when Dr. Emilia reverse-engineers Kipo's genetic modifications to transform herself into a Mega-Walrus.
• One of Terry Gilliam's Monty Python 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 Phineas and Ferb 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 Pinky and the Brain episode "Tokyo Grows", Brain attempts to take over Tokyo by disguising Pinky as the giant monster Gollyzilla, turning him into a giant with a reversed Shrink Ray, and then turning himself giant too and saving the city by fighting Pinky. Hilarity ensues when the real Gollyzilla shows up and Brain fights him instead of Pinky.
• Primal (2019): One of the show's protagonists is a female Tyrannosaurus rex named Fang, who ends up fighting another Prehistoric Monster at least Once an Episode. She fought other tyrannosaurs who ate her nestlings, a giant snake, wooly mammoths, giant bats, a Giant Spider and a monstrous ape-man. The show's other protagonist, Spear the caveman, also gets turned into a giant and fights said ape-man after it seemingly kills Fang.
• Steven Universe:
  • 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 get the Behemoth Battle that is Alexandrite versus Malachite, a fight that takes up nearly an episode, only interrupted by a watermelon riot.
  • "Change Your Mind" has two:
    • First off, Blue and Yellow Diamond (who aren't fusions) get into a fight when their views about their long-lost younger sister Pink Diamond get the better of them (one of them has had a Heel Realization, and it takes the fight for the other to have one too).
    • Then there's the Diamond Mecha, piloted by White Diamond versus the enormous fusion Obsidian, composed of Steven, Garnet, Amethyst and Pearl. 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 Sequel Series Steven Universe: Future has a climax where 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 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 Garnet, whom Yellow Diamond transforms into a giant: instead of fighting Steven, she gives him a Cooldown Hug that everyone else joins afterwards.
• The Transformers: The 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.
• The Wacky Adventures of Ronald McDonald: The climax of the rare sixth and final video The Monster O'McDonaldland Loch has a battle occur between Simon (the titular Stock Ness Monster) and his robot double built by the video's villain Stiles.

Real Life

• 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 Livyatan melvillei (the former a giant shark, the latter an older version of a sperm whale 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 (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 Herbivores Are Friendly being very much averted in real life with most species who aren't skittish being highly aggressive.
  • Here's one example of a hippopotamus engaging in a fight with a few white rhinos. 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 Covered in Scars 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.
