Behemoth Battle

Go To
"To fight monsters, we created monsters of our own."
Raleigh Becket, Pacific Rim

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 vs. Awesome. See also Everything's Better with Dinosaurs and Monster Mash. Primate vs. Reptile is an especially common variant, thanks to the iconic fight scene in King Kong (1933). Following Jurassic Park III (2001), the Spinosaurus vs. T. rex pairing also gained some popularity.


Any film set in a Lost World or 1 Million B.C. setting will likely have such a scene.

Examples are generally sorted chronologically.

  • 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 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.

  • 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, most notably with the King Ghidorah Expy, 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 monsters, aliens, 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.

  • BIONICLE: In the final battle between Mata Nui and Makuta Teridax, both of them are inhabiting enormous, multi-million-foot-tall robots.

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?
  • 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.

  • 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.

    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).
  • 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.
  • Godzilla: The Series: 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. Monobrow 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 entire 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 pretty much 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.

    Real Life 
  • 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.
  • 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 improbable) 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.


Video Example(s):


Thanos vs Darkseid

After supersizing himself to overcome a black hole created by Thanos, Darkseid initiates round two with the Mad Titan also increasing his size to even the odds.
