Kaiju



""Monsters are born too tall, too strong, too heavy, that is their tragedy.""

- Ishiro Honda

Giant Japanese monsters that assault Tokyo, hapless island explorers, or each other are called Kaiju. Just ask The Other Wiki. The really big ones are called "daikaiju" (literally "big kaiju").

Typically they arrive from somewhere Far Away. Whether that means space, Beneath the Earth, or a South Pacific island varies. Expect lots of Stuff Blowing Up to result, but, since Giant Equals Invincible, don't expect the explosions to actually hurt them. Do expect at least one case of Helicopter Flyswatter. Examples of this genre can range from straight-up Disaster Movie (Cloverfield, the first Godzilla movie) to all-out wrestling matches between People in Rubber Suits (Most of the later Godzilla movies). As this genre features a judicious application of Rule of Cool, expect the MST3K Mantra to be in full effect. Often, you'll only watch this kind of movie to see the monsters fight, which can often involve an Ultimate Showdown of Ultimate Destiny (such as King Kong vs. Godzilla.)

This is actually one of the oldest genres in film, dating back to the early days of cinema when special effects were new. Pioneers of the genre were The Beast from 20,000 Fathoms, King Kong, and The Lost World (which was actually the earliest example of the genre). The idea probably originates from thinking of dinosaurs as fantastic beasts or ideas about giant dragons. A Kaiju though will most of the time be a Single-Specimen Species, when even dragons often are a race of monsters.

Rent-A-Zilla is a Sub-Trope, where the work doesn't focus on the monster.

Compare Disaster Movie, Attack of the Killer Whatever, Robeast, and Attack of the 50-Foot Whatever. Has its roots in Tokusatsu. Not to be confused with over the top gambling by pointy-nosed men.

Anime and Manga

 * A few Digimon. A lot of Mons, in fact.
 * The Shito/Angels in Neon Genesis Evangelion.
 * The Evas themselves, having been cloned from Angels. Their armor just makes them look like Humongous Mecha.
 * When Haruhi Suzumiya gets particularly irritated (or, presumably, watches too much Evangelion, both of which might go hand-in-hand), she manifests Kaiju-like monsters in a Phantom Zone. Fortunately, there are also some people to fight the things (one of whom, who is known to be economical with the truth, says she dreamt up the people).
 * Voltaire and Hakutenou of Magical Girl Lyrical Nanoha. The two of them even get to battle in a heavily damaged city.
 * It was really more of a staring contest while Erio and Caro tried to bring Lutecia out of her Heroic BSOD, but they both fit the trope all the same.
 * The monstrous form of the Book Of Darkness also counts as a Kaiju.
 * Bleach has an example that involves Yammy Rialgo, whose release 'Ira' transforms him into a monstrous Kaiju.
 * Gilean-class Menos (and Arrancar formed from them) are probably big enough to count, too, even if they are considerably weaker.
 * In the CLAMP series Cardcaptor Sakura, Touya's pet name for his sister is "Kaiju", which is usually followed by Sakura shouting about how much she isn't one, complete with monstrous stomping about the house. Which naturally only adds to Touya's argument that she is a noisy kaiju.
 * And then she gets The Big card, and has to battle something and actual kaiju with the Create card.
 * Franken Fran had a massive human-like Kaiju that came from the sea and seemed intent on attacking an island town.
 * All members of the Heroic Tribe in Heroic Age are essentially GIANT SPACE MONSTERS. Which destroy planets on a regular basis.
 * The Mimetic Beasts from Godannar definitely qualify as Kaiju.
 * The eponymous Humongous Mecha in Dai-Guard ends up fighting a lot of kaiju.
 * Cenco and the other monsters in Cencoroll.
 * Done hilariously in Seto no Hanayome when Nagasumi is turned into a giant. San's father summons a large octopus to attack him.
 * The largest summoned animals in Naruto fit the bill in terms of size. The giant serpent is even named Manda after the Godzilla beast.
 * The Bijuu are just made of this. 9 giant monsters, at least one of which was once referred to as a natural disaster, which is far more in theme with the iconic Kaiju.
 * In Mahou Sensei Negima, the Sacred Beast of the Hellas Empire recently started attacking a gigantic shadow monster, causing local Strange Girl Haruna to start squeeing about kaiju battles. And Lovecraft.
 * Bokurano is about Humongous Mecha, not kaiju, but the confused populace in the work can't tell the difference, for a good reason.
 * In the Ranma ½ both Genma and Happosai have a secret Ki-technique that lets them grow to Kaiju-esque proportions. Then immediately collapse in exhaustion.
 * The demon beasts that the Big Bad Nightmare creates in Kirby: Right Back at Ya!.
 * Played with in Adventures of Mini-Goddess - the monster is giant compared to the mice and mini-goddesses, but he's objectively not much taller than a human.
 * The Varga and its counterpart the Dark Varga from the 1990s-vintage four-episode OVA series Luna Varga are pretty much both Godzilla with the Serial Numbers Filed Off. The biggest difference is that the Varga is in a symbiotic relationship with and controlled by Princess Luna, who can manifest him at her whim.  When he's not manifest, the only sign of their relationship is the dinosaur-like tail that the otherwise human Luna possesses.  And when he is manifest, she's embedded in a sitting position on his forehead, where she acts more or less as his pilot.

Comic Books

 * Superman has a recurring enemy named Titano, who is basically King Kong with the power to shoot Kryptonite-flavored laser beams out of his eyes.
 * One "Metropolis Mailbag" episode featured Superman's annual New Year's help-by-mail tradition interrupted by a fight between a gigantic Metallo and the new Toyman, a Japanese kid with a Super Robot. Between performing his tasks and trying to keep the battle from escalating, he also had to deal with several giant monsters awakened by the fighting: a massive butterfly, a Gorilla-Whale (A literal translation of Godzilla's name), and of all things, a giant purple Pikachu.
 * Fin Fang Foom of Marvel Comics, a giant Chinese dragon. Depending on the Writer, he's usually said to be an alien, a member of the race who invented the Mandarin's power rings.
 * Foom is a holdover from when Marvel published monster comics as a major source of revenue. Today, Marvel's Monster Island houses lots of Kirby-designed and inspired Kaiju. Some others who show up in modern continuity are the tree-like alien Groot and the lovable giant ape-monster Gorgilla.
 * Speaking of which, Marvel briefly had the rights to publish Godzilla comics, and featured him as part of the Marvel Universe. As with Marvel's other licensed property titles, he accrued a supporting cast of friends and enemies whom Marvel does own and who still pop up once in a while, such as Yetrigar the giant yeti, a giant robot named Red Ronin, and a Mad Scientist named Dr. Demonicus who specializes in mutating animals into Kaiju.
 * The Marvel Mangaverse version of Incredible Hulk.
 * The Monster Hunters are a Five-Man Band set in the 1950's who travel the world hunting down dangerous kaiju. They made friends with Gorgilla the ape monster, though.
 * During Walt Simonson's run of The Mighty Thor, Fafnir the dragon sure had the size to qualify.
 * Batman: Gotham After Midnight, a very bizarre miniseries, featured Bat-foe Clayface devouring people whole and growing into a gigantic mud-monster... which the Dark Knight fought with a Bat-mecha he had built for just such an occasion. Crazy Prepared, indeed...
 * Exiles had the Monster World arc, which envisioned Curt Connors, Bolivar Trask, Tony Stark, and Hank Pym as a team of Action Scientists fighting Kaiju in a transforming mecha. They fight it out with Fin Fang Foom in Japan at the end of the arc. It was awesome.
 * Avengers: The Initative: When the new 3-D Man is sent to a superhero team in Hawaii he finds out one of his missions is to protect the state from the occasional kaiju that wanders over from Japan.
 * Fire Breather anyone? Duncan's daddy, Belloc, actually calls himself king of the Kaiju and wants his son to one day take his place.
 * And don't forget that everyone refers to them as Kaiju or monsters, depending on their view.
 * One of the Justice League of America's oldest enemies is Starro the Conqueror (aka the Star Conqueror), a titanically huge, mind-controlling literal Starfish Aliens.
 * The comics mini-series Gigantic combines this with Truman Show Plot. The first kaiju on Earth, Gigantic, is trying to escape the mega-corporation that controls him, and the entire earth, having built it from scratch for a TV station.
 * The very first issue of Plop! had a story about "Kongzilla," a beast with the top half of a giant ape and the bottom half of a giant lizard.

Fan Works

 * Both Taylor and the Varga can manifest as several sizes of kaiju in the Worm/Luna Varga crossover Taylor Varga. As part of the semi-fictional Family of Lizard Folk, one of Taylor's various identities -- the one that's a hundred feet tall -- actually uses "Kaiju" as her name.

Film

 * The earliest example of the familiar Kaiju formula is present in the 1925 film The Lost World, in which a dinosaur wreaks havoc in London, setting the template for the genre before the sound era.
 * Godzilla ranges from antagonist to Anti-Hero with a Protectorate. His allies and enemies also count.
 * Mothra, usually trying to either aid humanity (and her friends the fairy twins) or defend her eggs from Godzilla.
 * Her Spear Counterpart is the eviler and spikier Battra.
 * Rodan, Manda, Baragon, and Varan all had their own movies as well before being brought into Godzilla's gang.
 * Godzilla's English Distaff Counterpart Zilla from Gorgo. Gorgo himself counts too, but he gets captured and held by those damn humans.
 * The Friend to All Children, Gamera, a heroic giant space turtle.
 * "♪KRAAAAAAAGERRRRAAA!!!♪ Friendtoallchildren, here to help!"
 * "Gamera is really neat! Gamera is filled with meat! We've been eating Gamera!"
 * King Kong is effectively the one memorable Western example, who assaults the Big Applesauce.
 * He is also - assuming this film actually existed - the earliest Japanese example!
 * Cloverfield is a reconstruction of all kaiju attack movies, reminding people that Kaiju has its roots in the Disaster film and how terrifying, deadly, and incomprehensible such an attack would be to an average citizen as it did in the first Godzilla film (before the American edits).
 * Insectosaurus of Monsters vs. Aliens, down to having the same backstory as Godzilla, though generally being a homage to Mothra.
 * The gigantic alien probe-robots also.
 * Reptilicus! The giant goop-spitting snake-dragon that destroyed Copenhagen!
 * The Giant Claw! The flying battleship Giant Antimatter Space Buzzard from 17,000,000 B.C.!
 * The Stay Puft Marshmallow Man from Ghostbusters.
 * Mongo from Shrek 2. It especially works if Drury Lane is in Far Far Away, since Kaiju rarely live in Close Near By.
 * Mega Shark vs. Giant Octopus. The octopus attacks Tokyo Bay, but for some reason we never see any scenes of this, whereas the giant shark takes a bite out of the Golden Gate Bridge in San Francisco.
 * The Kraken in Clash of the Titans. City-destroying? Check. Impervious to normal weapons? Check. Huge? Check. The Remake takes that last part Up to Eleven; one of the thing's tentacles is about half as long as the city of Argos.
 * Street Fighter has a tribute to these, with Zangief and E. Honda duking it out in a model city.
 * Referenced in Deep Rising, at the end of which something unseen but HUGE moves toward the beach and the survivors, knocking down trees as it approaches. Not to mention its own multi-armed, lamprey-headed octopus with mouths at the end of each arm. Its head fills a ballroom and its tentacles can reach throughout an ocean linear.
 * Thunder of the Giant Serpent has one of the largest snakes in cinema—it's head being bigger than a car when it gets big enough.
 * The Beast from 20,000 Fathoms is an early prototype of this genre.
 * Since the film The Giant Behemoth/Behemoth: The Sea Monster (Department of Redundancy Department or Sadly Mythtaken, your choice) is basically the same film, it counts as one as well—with the only addition of it being able to project radioactive waves from its whole body.
 * The Blob can be seen as a Blob Monster taken to this level as it grows larger. The 1980s Remake's climax is a full on Kaiju rampage.
 * A lot of Blob Monsters get Kaiju like as they get bigger.
 * Gappa: The Triphibian Monster fits the bill.
 * Yongary: the Monster from the Deep, its remake Yonggary, and 2001 Yonggary are basically Korean Godzilla-knockoffs. 2001 Yonggary has it fight another Kaiju, named Cykor.
 * Aside from King Kong, there are other giant ape Kaiju. These include The Giant Peking Man, Konga, A.P.E., and King of the Lost World.
 * It Came From Beneath The Sea features an Octopus of Kaiju Proportions. Several other films (usually titled things like Octopus and Octopus 2: River of Fear) feature similarly large giant cepholopods, but aren't as good as the Harryhausen Movie.
 * The title monster from Supercroc is a Kaiju-sized Crocodilian, with appropriately thick armor.
 * The dragons from D-War fit the bill.
 * The Kraken from Pirates of the Caribbean.
 * Iron Golem/Minotaur in Pulgasari isn't too big, but given its attacking medieval villages, it fits the bill. Notable for being from North Korea, and eventually banned there.
 * An American Direct to Video film called The Adventure of Galgameth reset it in Medieval Europe, but has the same plot as Pulgasari, right down to the titular monster's weakness to salt water and growing by eating iron and its derivatives.
 * The Daimajin series' titular monster is an ancient demon-god. It too battles medieval forces, but with a stone body and mystical powers. It also exists to punish the wicked—but has unreasonably high standards. So, each time after it frees the oppressed villagers from the evil warlord/king, it goes on to attack them.
 * The space monster Guilala from The X From Outer Space is one of the most bizarre Kaiju to have its own films.
 * Talos from Jason and the Argonauts is made of bronze, but definitely fits the bill.
 * The Giant Amoeba and "Rat-Bat-Spider" from Angry Red Planet fit the bill.
 * Kraa: The Sea Monster is actually from Outer Space, but is 200 ft tall.
 * Zarkorr: the Invader
 * The last shot of Deadly Spawn features one of the monsters grown larger than a house.
 * The Ymir from 20 Million Miles to Earth just scrapes in as it constantly grows as it remains on earth.
 * The giant amoeba-like life form from the finale of Evolution certainly counts.
 * The oliphants from The Return Of The King, while smaller and less invulnerable than other examples, should get special mention for being an entire herd of Kaiju. And dressed up for battle, no less.
 * In Star Wars The Phantom Menace the Sando aqua monster would qualify, as it spends most of its screen time devouring smaller sea monsters.
 * Though not as huge as many on this list, the monster of the Korean film Gwoemul, or |The Host, is in many ways a tribute to the genre.
 * Numerous films by SyFy Channel Original Movie and The Asylum.
 * Jack Frost at the end of Jack Frost 2: The Revenge of the Mutant Killer Snowman.
 * A commercial for the fast food chain Hella Burger in the Slasher Film Drive Thru depicts Horny the Clown as one of these.
 * The Troll Hunter has the giant Jotannar Troll, at over 200 ft tall.
 * The fairly obscure Daigoro vs. Goliath, produced by Tsubaraya Productions.
 * Sharktopus, anyone?
 * Pacific Rim reconstructed and paid loving tribute to the genre, and was possibly the first Western film to actually use the word "kaiju" for its giant monsters.

Literature

 * Cthulhu Mythos: Not Japanese, but it came from (hyper)space, is huge and lies beneath the Pacific/Antarctica.
 * Agog Press' Daikaiju! anthology is built around these, and features a number of really weird ideas. How weird? Groundsurfing on the shockwaves made by kaiju's feet as they walk around.
 * The avanc from The Scar is an unusual variant, as this gargantuan marine creature didn't destroy a city by stomping through it, but by dragging the floating city of Armada to its doom in the titular Scar. Or not. YMMV.
 * Possibly the sandworms of Dune could qualify, although Arakis doesn't have skyscrapers for them to trash.
 * At the end of Unseen Academicals, Ridcully informs Ponder that
 * Great A'tuin and the four elephants riding its shell would qualify, if they weren't supporting the world rather than stomping all over it.
 * And an earlier book had a giant creature from the Dungeon Dimensions steal the form of a famous actress, escape from the Silver Screen and go on a rampage across Ankh-Morpork and climbing the UU's Tower of Art carrying a screaming ape in an inversion of King Kong.
 * Something inconceivably huge and six-legged walks across the highway in Stephen King's "The Mist", nearly stomping the protagonists' SUV. Its full size is not specified, as its body is so high that it's obscured by the fog.
 * Gojiro by Mark Jacobson is a deconstruction of Kaiju monsters told from the point of view of the monster Gojiro and his human partner Komodo as they attempt to bring about world peace and prevent the testing of a next-generation nuclear weapon.
 * In The Iron Man, the children's novel by Ted Hughes that was the basis for The Iron Giant, the Iron Man confronts an alien dragon creature somewhat smaller than Australia. While this plot point wasn't featured in the movie, it was featured in "The Iron Man; The Musical", a concept album by Pete Townshend of The Who inspired by the novel.
 * The stavanzer, or thunder-eater, from Icerigger is a slug-like herbivore over a hundred meters long, and it's mentioned that such creatures have been known to destroy tran settlements.
 * Monster Blood's title substance typically makes things grow to giant size, but the second book took it a step further when the climax involved the protagonist eating monster blood to fight a giant hamster eating his school. True to kaiju form, this involves a giant wrestling match.

Live-Action TV

 * Abbadon from Torchwood is a giant life-sucking daemon which, when released, goes on a rampage in the streets of... Cardiff.
 * Rampant in Super Sentai as well as their American import Power Rangers; less common in Kamen Rider, where the monsters tend to stay small-sized. (Except Kamen Rider J.)
 * Kaiju Big Battel is one giant Professional Wrestling-based parody of this.
 * The standard Monster of the Week of the Ultra Series.
 * Most Kyodai Heroes actually.
 * Jumborg Ace
 * Fireman
 * Mirrormon
 * Spectreman
 * Giant Robo Live Action series
 * Zone Fighter
 * Ambassador Magma Live Action series
 * Iron King
 * Ike! Godman
 * Ike! Greenman
 * Megaloman
 * Chou Sei Kantai Sazer X
 * SCTV had a sketch called "The Tim Ishimuni Show", which featured a giant talking monster named Grogan (played by John Candy in a monster suit), who doesn't really go by the Kaiju stereotype of crushing things.
 * This memorable GARMIN commercial from the superbowl.
 * Agon: The Atomic Monster/Giant Phantom Monster Agon is one of the earliest attempts at a TV show about a giant monster. It only had 4 episodes.
 * A Doctor Who story called Invasion of the Dinosaurs contained Exactly What It Says on the Tin.
 * Another story called The Seeds of Doom features an alien plant called a Krynoid, which eventually grows to a size of several tens of feet tall. The Doctor says it will max out at about the size of St Paul's Cathedral (at which point it will release thousands of seeds, dooming all animal life on Earth).

Music

 * Doctor Steel's song "Atomic Superstar", featuring the original Kaiju, Godzilla.
 * Blue Oyster Cult's "Godzilla", predictably enough.
 * Played for laughs in the Arrogant Worms' "Tokyo Love Song".
 * From Mike Nesmith's "Elephant Parts" (1981): Her Name Was Rodan, and she lived in the ocean off Japan.
 * Surf rock revival band "Daikaiju" takes cues from many old Kaiju and sci-fi films. Song names include: The Trouble With Those Mothra Girls, Son of Daikaiju, Farewell to Monster Island, etc. The music itself is pretty damn good
 * Rapper MF Doom's alter ego King Geedorah. The album, Take Me To Your Leader, also features a number of rappers under various Kaiju names (Rodan, Gigan, Jet Jaguar etc).
 * "The Cockroach That Ate Cincinnati" by Rose & the Arrangement.

Newspaper Comics

 * Garfield usually mocks bad horror movies when it goes pop-cultural, but on one occasion the title character saw a news interview with "a prehistoric monster who rose from the depths of the Earth to stomp on Tokyo, and has written a book about his experiences (of course.)"

Oral Tradition, Folklore, Myths and Legends

 * Norse Mythology brings us Jormugandr, the World Serpent. Enormous reptilian beast that will rise from the sea surrounding the world and has deadly breath. Sound Familiar? Regular monster, no way. You wanna take this down, your name best be Thor, god of thunder. Not to mention the giant wolf Fenrir.
 * There's also the giants, especially Ymir.
 * Kraken and Leviathan are gigantic.
 * Classical Mythology has a few of these as well. Part of this was due to the idea that the Heroes of their myths were thought to have been giants themselves, standing roughly 3-4 times the size of modern men with the Gods and Titans being roughly that scale to them. But to bring up specifics, the titan Typhon with his multiple heads and burning body definitely counts. The original Chimera was treated as such, as were many of the monsters defeated by Hercules (Nemean Lion, Hydra, and the taming of Cerberus). The monsters Scylla and Charybdis also fit the Kaiju mold, being unstoppable by mortal men.
 * Many of the most dangerous Giants and Dragons were essentially prototype Kaiju.
 * In Hindu Mythology, there's many a Rakshasha and Naga of immense size. Of note are Kumbhakarna, who was a giant even among the monstrous Rakshasha. His brother, Ravana, for his many heads and hands. Then there's Ananta-Sesha, a world serpent of a much more benevolent bent.
 * Then there's Mada, an Asura that can make itself so large that it's capable of swallowing the universe.
 * Some accounts of the Garuda depict this gigantic bird as being so large, it could pick up Godzilla and carry him off.
 * From Abrahamic traditions and The Bible, we have the lords of the animals: Leviathan, Behemoth, and Ziz. One's a giant aquatic dragon, the other an immense beast with a massive tail, and the last a giant bird.
 * Older Than Dirt: From the mythology of the Babylonians, there's the monstrous Eldritch Abomination goddess Tiamat and her progeny. Mesopotamian myth also involves gigantic dragons.
 * There's a Native American legend (which nation is unknown) involving a giant rattlesnake several hundred miles long.

Tabletop Games

 * Dungeons & Dragons
 * The old Basic/Expert/etc. version of the rules had a method for super-sizing normal monsters. They also had critters that qualified as this trope right out of the box, like the earthquake beetle.
 * No discussion of giant monsters in D&D is complete without mentioning the legendary Tarrasque. Only one exists on any given world; this reptilian monstrosity awakens every century to destroy everything in its path, devouring all life and reducing the countryside to rubble, and is completely unkillable without resorting to godlike magic.
 * In Pathfinder, the Tarrasque, while still unique, is one of a whole family of unique kaiju created by the apocalypse god Rovagug. Which is itself an unbelievably gigantic insect-Eldritch Abomination imprisoned in the molten heart of the world in a cage whose bars are strong enough to hold it in, but wide enough to allow its comparatively tiny and ineffectual spawn to escape.
 * The original Oriental Adventures supplement introduced a number of creatures called "Gargantuas" that were Captain Ersatzs of Godzilla, King Kong, and Mothra.
 * Test of the Samurai adventure for the Oriental Adventures campaign setting featured a gigantic psychic monster called a "Krakentua", which is best described as Cthulhu, sans wings, in a kimono.
 * Dragon magazine #289 proposed "Kaiju" as a template, enabling the DM to turn any Animal, Magical Beast or Vermin in the Monster Manual into a fifty-foot armour-plated monstrosity capable of destroying Tokyo Nakamaru.
 * Spelljammer has Witchlight Marauders, which function as both this and hatchery for a Horde of Alien Locusts. That's the Primaries at 200' to 500' long (Secondaries are still massive, but much smaller, derivatives of the Primaries at 20', and Tertiaries are human sized at 4' to 6' and still deadly), which were created with the explicit purpose of stripping life-bearing planets down to the bedrock. For true cosmic horror, there are the Space Marauders at over 1000' long, which create Primaries and drop them onto planets and function as living spacecraft as well.
 * The collectible miniatures game Monsterpocalypse is all about giant monsters (along with Humongous Mecha and alien invaders) duking it out.
 * Exalted has its share of giant, rampaging monsters. Most of these are behemoths, created either by the Fair Folk for use in their reality shaping battles, or by the Primordials, for shits and giggles. Occasionally, an elemental dragon will ascend to such a level of spiritual development that it goes insane. Also, elder Lunar Exalted can use their Voluntary Shapeshifting to change into an incredibly strong monster that dwarfs cities.
 * One of the more distinctive behemoths of the setting is Juggernaut, Mask of Winters' undead citadel-beast that aided him in sieging Thorns.
 * And then you've got the hekatonkhires, which are often what happen when behemoths die. One of them, Vodak, ate a city.
 * The game Gammarauders featured gigantic cyborg animals and dinosaurs with a variety of weapons sprouting from their bodies. Few things are more terrifying than a giant cybernetic Penguin waddling toward you, wrecking buildings as it comes.
 * The Creature That Ate Sheboygan, a wargame from SPI, is about the title city being attacked by a giant monster. One player defends the city with the National Guard and the other plays the monster.
 * Star Fleet Battles includes a number of Monsters of various types (some living, some not), mostly for solo scenarios. One such scenario pays homage to the above game with the subtitle "The Creature that ate Sheboygan III".
 * In Warhammer 40,000 the larger Tyranid creatures, known as Biotitans, definitely qualify.

Video Games

 * Resistance 2 has the Leviathan, a giant monster that roams the flooded streets of Chicago.
 * Spoofed heavily by the Lungfishopolis level of Psychonauts: one mind is portrayed as a city of tiny lungfish-like creatures, meaning that Raz is gargantuan compared to them. Due to his distinctive headgear, the citizens immediately nickname him Goggalor. The Boss Battle of the level is the Villain with Good Publicity kaiju, who's hailed as a hero to protect them from "Goggalor" (and a Shout-Out to Ultraman)
 * Destroy All Humans! 2 has the "Kojira Kaiju Battle" mission, a Godzilla parody complete with someone screaming "Kojira! Aieeee!", atomic breath, and those weird anti-Kaiju tanks common in Godzilla films. Naturally, it takes place in Japan.
 * X-COM: Apocalypse has the Overspawn, giant aliens dropped by the Mothership for the sole purpose of rampaging all over the cityscape. They're actually pretty weak since they're usually up against the best of X-COM manufactured vehicles and weapons by the time they appear. Some players just leave them alone since they have a tendency of accidentally killing themselves when they get too close to a building they knock over.
 * Speaking of rampaging, the characters you use in the Rampage series of games.
 * War of the Monsters is a Fighting Game in which the player can choose one of ten different Kaiju, including pastiches of King Kong and Godzilla and an old school Japanese giant robot. The game has a noticeable cheesy 1950s sci-fi feel to it, featuring huge, fully destructible city environments.
 * King of the Monsters, a Kaiju wrestling game.
 * Kyogre and Groudon of the Pokémon games. Sootopolis was the unlucky city that had front row seats to their coming. Heck, when the time came for Pokémon Special to adapt the Ruby/Sapphire games, the artist said that he wanted to recreate scenes from his favorite monster movies when he was drawing the volumes that involved those two's disaster-filled awakening and eventual battle.
 * Following them are Palkia, Dialga, Giratina, and Arceus, who all possess semi-godlike powers that cam tear the very fabric of reality.
 * Tyranitar, Hydreigon and Volcarona seemed to have been inspired by Godzilla, King Ghidorah, and Mothra respectively
 * The Weapons of Final Fantasy VII are quite distinctly Kaiju, right down to incoherent roars, being vaguely humanoid, coming from the depths of the ocean, attacking major population centres and making craters on the main map screen when finally killed.
 * Age of Mythology's expansion brings Titans to the battlefield. They're huge, they can trash a city on their own, and it takes a ton of firepower to bring one down. Don't let your enemy summon one.
 * Spore gives us Epic creatures which you can encounter early on in the creature stage. Later on in the space phase, you can make your own and send them to destroy cities for you!
 * The Elder Scrolls IV: Oblivion has at least two. First and foremost is Mehrunes Dagon, Daedric prince of destruction, and Jyggalag, Daedric prince of order. Although Jyggalag is the smallest of the two, he is taller than the city walls and is very powerful.
 * Crush Crumble and Chomp gave the player four cities to destroy (Tokyo, New York City, Washington DC and San Francisco) and six monsters to destroy with (along with the ability to make your own monster).
 * Kabuto from, well, Giants: Citizen Kabuto.
 * The whole idea is sort of deconstructed in Shadow of the Colossus.
 * Being a spinoff of Ultraman, Kaiju Buster Powered naturally has plenty of Kaiju. However as it's also heavily inspired by Monster Hunter, said Kaiju are more then capable of being taken down by humans with swords and energy weapons.
 * Inspired Metal Gear Solid 2: Sons of Liberty. By Word of God, the character designer Yoji Shinkawa was disappointed with the design of Godzilla In Name Only in the notoriously half-assed Roland Emmerich Godzilla, and so designed Metal Gear RAY's body, movements and Mighty Roar after how he would have redesigned Godzilla to look. There's also allusions made both in-game and in Word of God comparing Solid Snake to Godzilla and Raiden to King Kong, although this is more of a Kaiju version of Faux Symbolism.
 * Parodied in the non-canon Metal Gear Solid: VR Missions and Snake Tale E: External Gazer, where having giant Kaiju versions of the game's standard Mooks is kind of a recurring in-joke. Genola is just a giant Genome soldier in white Arctic camouflage, and Gurlugon is a Gurlukovich soldier with fins along its spine and the ability to shoot paralysing Eye Beams.
 * Disgaea: FLONNEZILLA! Flonne's final attack. She dresses up in a patchy dinosaur costume and starts terrorizing the targets, with toy planes on wires flying around her. She finishes it up by breathing fire on the target.
 * Mass Effect 3: A Reaper vs The 

Web Comics

Western Animation
"Captain: Uh, folks, we're experiencing some moderate Godzilla-related turbulence at this time, so I'm going to go ahead and ask you to put your seatbelts back on. When we get to 35 thousand feet, he usually does let go, so from there on out, all we have to worry about is Mothra, and, uh, we do have reports he's tied up with Gamera and Rodan at the present time. Thank you very much."
 * The Powerpuff Girls frequently fight Kaiju assaulting their City of Adventure when not engaging their Rogues Gallery. One is actually called a Robeast.
 * Avatar: The Last Airbender has four of these: The Unagi in Kyoshi Bay (that needs water, and therefore cannot attack the village); The Serpent from the Serpent's Pass (hence the name); Koizilla, the Fan Nickname for the Aang/Ocean Spirit Cross-fusion; and the currently unnamed Vine Monster that can be created by Huu.
 * In the Kim Possible episode 'Partners', Doctor Drakken and DNAmy create a gigantic Godzilla-like creature that proceeds to destroy the town's fast food area. It doesn't stay destroyed, though.
 * Mecha-Barbra Streisand and her three opponents from South Park.
 * Metalocalypse: Mustakrakish, the giant Finnish lake troll. No, not THAT kind of giant troll.
 * One of the early Superman Theatrical Cartoons had the Man of Steel having to deal with a dinosaur the size of an office building that had thawed out of an ice block and attacked Metropolis.
 * Trypticon, the city-form Decepticon from the original Transformers cartoon, resembles Godzilla in his robot mode, and is an obvious homage to classic kaiju films.
 * Even more so in Transformers: War for Cybertron, he's taken the Godzilla homage Up to Eleven, with some Mechagodzilla added in to boot. And not forgetting the titanic Decepticon City Transformer, Skorponok.
 * Dexter's Laboratory features several kaiju. More memorable ones involve an extra-dimensional horror with many eyes and tentacles (the start of a Stable Time Loop) and iconic Dexter "oops". Another episode involved Dexter and Dee Dee becoming giant monsters by drinking Dexter's monster potions and having an all out battle (complete with Calling Your Attacks). Finally, there's Badaxtra, the monster of the original Finale who nearly destroyed the world.
 * An episode of Duck Dodgers parodying anime and other Japanese tropes had a kaiju called Maninsuit.
 * The Inhumanoids premiere episode had Tendril shambling through San Francisco, trashing streets and tossing cars at helicopters.
 * Star Wars: The Clone Wars features the Zillo Beast, which is a Kaiju for the Star Wars Universe, though its plot is similar to that of King Kong...initially.
 * My Little Pony: Friendship Is Magic had a rampaging blue bear that was covered in stars and was as large as your average house even when it's on all fours. This is the Ursa Major.
 * In one episode of What's New, Scooby-Doo? set in Hong Kong, the Monster of the Week is a robot designed to look like Shaggy which is turning into a kaiju. And at one point the real Shaggy is put in a rubber suit in a model city to convince him.
 * The Simpsons
 * Lisa is sentenced to a lifetime of horror on Monster Island, where she is chased by monsters despite its Non-Indicative Name.
 * As the family is leaving Tokyo, the plane warning lights for Godzilla holding the plane light up.


 * A hobo tells the story of Paul Bunyan where he pushes Rodan, who then falls over Babe the ox. Lisa informs him that never happened.
 * ReBoot had "Nullzilla" (from the episode of the same name), a kaiju made up of the "nulls" that used to be inhabitants of Mainframe. Of course, they happened to have a set of combining robots to fight it with.

Real Life

 * Amphicoelias was by some estimates the single largest land-based animal—never mind dinosaur—on record. 40 to 60 metres (130 to 200 ft) in length, and may have had a mass of up to 122 metric tons (135 short tons).
 * At two meters long, Anomalocaris wouldn't qualify as a kaiju today, but considering it lived in an era when the largest non-Anomalocaris animals tended to be measured in a few inches, it certainly was at the time!
 * This UKIP Party Political Broadcast turns the EU into a Giant Blue Octopus that attacks London with Combat Tentacles whilst warning against the EU attacking UK culture and ideals. UKIP - short for the UK Independence Party - is mainly concerned with Euro Scepticism.
