- Attack on Titan features the people-eating humanoid giants called "Titans", which humanity has to fight either with highly specialized combat gear that allows them to maneuver in three dimensions and slash the napes of their necks, or with a Titan of their own who can transform from a human. The Colossal Titan in particular, being 60 meters tall, definitely qualifies.
- 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 CLAMP series Cardcaptor Sakura, Touya's pet name for his sister is "Kaiju" (or "Dinosaur" in Nelvana's English dub), 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.
- Cenco and the other monsters in Cencoroll.
- The eponymous Humongous Mecha in Dai-Guard ends up fighting a lot of kaiju.
- A few Digimon. In particular, Tyrannomon even has the Godzilla-ish back spikes, and his larger, darker Palette Swap, Dark Tyrannomon, was once used for a very Godzilla-evocative scene when the battle was taken into the human world. Powers That Be resisted the urge to use the distinctive Godzilla roar. In general, the Digimon franchise is a whopping cyberspace of digital Kaiju fights, with some Mega-leveled Digimon being Kaiju-sized akin to the Ultra Series example below.
- Dragon Ball features loads of massive creatures and monsters, most of which dwarf even the dinosaurs that are still around.
- Oozaru/the Great Apes, the form which Saiyans who have tails can turn into when they look at the moon is at least 50 feet tall and serves a Shout-Out to both King Kong and Godzilla with their Breath Weapon. The Bardock special and flashbacks show the Saiyans could effectively conquer entire planets as Great Apes and older Saiyans even retain their intellgence once they transform. Sadly Toriyama put less focus on the Great Ape transformation as the series went on, so these giant monkeys haven't been seen since Vegeta and Gohan transformed in the Saiyan Saga.
- Similar to the Saiyans, Namekians have Great Namek form, e.g Lord Slug's city crushing giant form which nearly killed Goku.
- Porunga more so than Shenron resembles a Kaiju, so much so West City freaks out in typical Godzilla-fashion when he is summoned at the Capsule Corp. Subverted however as Porunga is much nicer than he looks and Bulma even calls him cute.
- A more traditional Kaiju would be Hirudegarn from Dragon Ball Z: Wrath of the Dragon a humongous fire-breathing Ancient Evil that was sealed away, before being released. At full power it managed to defeat the Z-Fighters and destroy most of West City, before Goku turned Super Saiyan 3 and used Dragon Fist to kill Hirudegarn.
- Dragon Ball GT featured multiple giant monsters, most notably two of the Shadow Dragons Rage Shenron and Naturon Shenron have massive city destroying forms.
- Funnily enough famous Kaiju such as Godzilla (on TV), King Ghidorah and Gamera cameo in the franchise though they’re quite smaller than their usual sizes.
- Cell’s successor Cell Max from Dragon Ball Super: Super Hero definitely qualifies being the size of a building by the Final Battle and in a Shout-Out to Shin Godzilla can Beam Spam out of his body not just his out of his mouth. Piccolo in his Orange Form goes giant himself leading to a Kaiju-sized slug fest between the two. However since size never matters in Dragon Ball, the average-sized Gohan was able to take down Cell Max pretty easily upon awakening his Next Tier Power-Up “Beast Gohan” with only Piccolo helping by holding Cell Max in place for Gohan’s Special Beam cannon.
- Franken Fran had a massive human-like Kaiju that came from the sea and seemed intent on attacking an island town. Turns out that it's just a girl whose wish of living with the whales was granted by Professor Madaraki. She's just there to find her mom so she could give her the great news that she's now pregnant. Happy end!
- The Mimetic Beasts from Godannar definitely qualify as Kaiju.
- 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, she also dreamt up some people to fight the things.
- All members of the Heroic Tribe in Heroic Age are essentially GIANT SPACE MONSTERS. Which destroy planets on a regular basis.
- Kaiju Girl Caramelise tells the story of Kuroe Akaishi, a high school girl who turns into a Kaiju called Harugon whenever she gets particularly emotional, usually when it involves her crush Arata Minami. Whenever she gets emotional but is able to contain herself, she usually undergoes a Partial Transformation manifesting as a scaly hand, dorsal spikes, a tail, etc.
- Many of the larger Demon Beasts that the Big Bad Nightmare creates in Kirby: Right Back at Ya!.
- The main character of Kiriwo Terrible transforms himself into a Kaiju to fight the Kaiju attacking his city.
- Voltaire and Hakutenou of Lyrical Nanoha. The two of them even get to battle in a heavily damaged city. There's also the monstrous form of the Book Of Darkness.
- Done hilariously in My Bride is a Mermaid when Nagasumi is turned into a giant. San's father summons a large octopus to attack him.
- My Hero Academia
- There’s a character whose quirk is “kaiju” and lets him turn into a kaiju.
- Then there’s Godzillo, who’s a walking Godzilla shout-out whose quirk “Toho” lets him turn into Godzilla and references the company that owns Godzilla.
- Naruto:
- The largest summoned animals fit the bill in terms of size. The giant serpent is even named Manda after the Godzilla beast.
- There's also the Tailed Beasts: 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. Lampshaded by Guy, when Kurama and Gyuki fight the five other Tailed Beasts Matatabi, Isobu, Kokuoh, Saiken, and Chomei.
Guy: "It looks like the battle of Kaijus!"- The Tailed Beasts themselves are revealed to be fragments of the Ten-Tails the original Tailed Beast and the largest of them all, this beasts power is so great that when Naruto tried to measure its power, he got sensory overload instead.
- The first Hokage, Hashirama Senju was so powerful, he could summon gigantic wood golems and wood dragons to fight. Cranked up to eleven, during his fateful battle with Madara. Hashirama summoned a wooden statue of Avlokiteshvara so huge, all Kaijus look like dwarves in comparison. Even a full sized Kurama looks like a normal mouse compared to a six foot tall human.
- In Negima! Magister Negi Magi, the Sacred Beast of the Hellas Empire recently started attacking a gigantic shadow monster, causing Haruna to start squeeing about kaiju battles. And Lovecraft.
- The Angels in Neon Genesis Evangelion. There's also the Evas themselves, having been cloned from Angels. Their armor just makes them look like Humongous Mecha.
- One Piece (thanks to Eiichiro Oda's love of drawing big creatures) has an overabundance of giant monsters (see here
). While a good many are friendly, most are just building-sized terrors who can destroy ships and gobble up people like mints. The Monster Trio (Luffy, Zoro, and Sanji) actually got their namesake from being able kill a giant Sandora Lizard in Alabasta.- The Sea Kings are perhaps the most prolific Kaiju in the franchise; all four oceans are crawling with them and ones in the Calm Belt are even bigger in size and number. Defeating just one Sea King is the mark of a superhuman in One Piece. In Fishman Island, it’s revealed Princess Shirahoshi can control Sea Kings, which means she’s one of the Ancient Weapons: Poseidon.
- Special mention to the Bananawani, (gigantic crocodiles with bananas growing out of their heads) big enough to chomp stone and they even prey on the aforementioned Sea Kings, being their only known natural predator to this date. However, they’re hit with The Worf Effect pretty badly.
- One Piece Film: Strong World (the one written by Oda) has loads of Kaiju as the Big Bad Shiki injected animals with IQ turning them into superbeasts, such as: the land dwelling octopus, a massive long armed bear who suplexes its foes, and a six-legged tiger. While the Straw Hats (especially the Monster Trio) can handle them, Shiki threatens to unleash the creatures across world, starting with East Blue, the home sea of the original five crewmates.
- Nola, the 200-year-old humongous snake from Skypeia, even among the many monsters in the series deserves recognition, being big enough to wrap itself around a massive forest, No-Sell attacks from Zoro and Wyper, and even swallowed Luffy and several others and kept them in its belly. Subverted, however, as Nola is actually quite friendly and good-natured.
- Patlabor:
- Used in episode 3 of Mobile Police Patlabor: The Early Days, where the monster walks off into the sea immediately after it appears. It has an appearance similar to Gaira from War of the Gargantuas ...and Hiromi Yamizaki.
- The fourth and 19th episodes of Patlabor: The TV Series feature different monsters. The first is a mammal of some sort, a genetic experiment that escaped, and the audience only catches a brief sight of it — it's an animation cameo of Dirty Pair's Mughi. In episode 19, the monster is an underground-adapted Dragon, which Noa insists on calling it a real Kaiju, while Kanuka insists on calling it a surviving Dragon descended from the ones in the middle ages.
- Mobile Police Patlabor contains a different Kaiju story that involves an airline crash that accidentally releases a genetic experiment that rapidly grows into an amphibious monster that Division 2 (among others) get called out to deal with. WXIII: Patlabor The Movie 3 was loosely based on this story.
- Pokémon: The Series:
- Legendary Pokémon are anywhere from "extra-large" to "titanic" in size, especially if it's a more "beastly" Legendary (Groudon, Rayquaza, Giratina). Non-Legendary examples include the cliff-sized Dragonite in "Mystery at the Lighthouse" and the skyscraper-tall Tentacruel in "Tentacool and Tentacruel".
- Arceus' rampage in Pokémon: Arceus and the Jewel of Life is reminiscent to the kaiju film genre.
- Fittingly, the Pokémon movies are distributed by Toho, the kaiju progenitors.
- 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.
- In Shinzo, Enterrans are basically mons that populate the earth After the End. They don't get ginormous... usually. One Big Bad has as The Dragon an actual three-headed dragon named Grendora. Grendora is positively enormous, shoots ice blasts, and uses canned Godzilla roars.
- Queen Taratects in So I'm a Spider, So What? are massive and extremely powerful. A single Queen was able to wipe out a fully-manned fort and the army attacking it. Also noted is Fenrir, a wolf capable of taking bites out of similar forts.
- SSSS.GRIDMAN, from the creators of the Ultra Series, has kaijus being fought by Gridman and the Neon Genesis Junior High Students.
- Many larger Capture Beasts in Toriko fit the role. The Four Beasts and their master beast fit this especially. More powerful beasts in the Gourmet World make Godzilla look small.
- To the Abandoned Sacred Beasts has the Behemoth, Arthur Allston's Incarnate form. This 164-foot-long monster resembles a sauropod crossed with a monitor lizard, and his thick hide makes him all but impervious to the cannons and muskets of the Civil War-era soldiers that are trying to slow him down as he plods inexorably toward a railroad bridge.
- Many of the gigantic monsters from Yu-Gi-Oh! count, especially the ones who are extremely powerful in-universe. For example, Exodia, the Egyptian Gods, the Great Leviathan, the Sacred Beasts, the Earthbound Immortals, etc.
