Attack of the 50-Foot Whatever

We got BIG trouble!^note

"There were some serious copyright issues with that, so she is not the 50-Foot Woman. She's the 49-Foot-11-and-Three-Quarters-Inch Woman."

— Carlyle describing Susan, Monsters vs. Aliens review

This is, in essence, Incredible Shrinking Man turned on its head, where the ray gun that zapped the character was set on "Grow" instead of "Shrink". And the protagonists have a huge problem to deal with.

For maximum disaster potential, the victim of the growth is usually a pet, wild animal, baby human or other character without a firmly developed sense of morality or sentience who might innocently topple the downtown skyscrapers without really meaning it. If the victim is a normal person, the growth process will inevitably fry their synapses or they'll go on a power trip with delusions of Godhood, requiring the hero of the story to find a way to put them back to normal just the same.

This generally violates the Square-Cube Law, but that's okay. For humans, expect Magic Pants to be in effect — can't have a giant naked person, after all. The Moral Guardians would freak. Their voices may get lower as well.

Differs from Shapeshifting in that the character generally just becomes a much bigger version of whatever they were before. Pet monkeys and lizards, however, tend to seamlessly morph into either King Kong or Godzilla knock-offs along the way, no matter what their original species were. (And if that happens, expect two or more Japanese tourists to shout "Ahh! Gojira!" and run away.)

Episodes of this kind are quite likely to include a Stock Parody or Homage of King Kong: The 50-foot (15-meter) whatever will climb a tower, often with a Damsel in Distress in hand and airplanes buzzing like flies. Imitators often omit the Downer Ending where Kong falls to his death, though. See "King Kong" Climb for examples.

If the hero wants to fight back, he may be in for a Colossus Climb, if deploying Humongous Mecha is out of the question. Counterattacking from the air is another option, but risks invoking Helicopter Flyswatter.

A standard plot for animated shows, but tough to pull off seriously for live action. B-Movies latched on to this trope for a time. After all, why settle for the standard-size Monster of the Week when you could have a giant one? Advances in special effects technology have kept this from becoming Discredited.

Note that, in real life, no living organism of such a size can exist (the dinosaurs were the biggest land animals ever, but their actual size was nowhere near the likes of King Kong or Godzilla as we see them in the media). As an animal gets bigger and bigger, it must use more and more resources of the body (bones, muscles, etc) just to sustain itself on its feet, and will require higher quantities of food. See here for details.

Advertising

CSL (a British sofa company) have parodied this trope to extremes in their adverts with a Giantess.
A 2009 commercial for Vodafone Iceland features giant men and women walking around Iceland.
A commercial for Pepto-Bismol had various kaiju and a 15 meter Woman doing the "nausea, heartburn, indigestion" dance. Do we really want to consider the implications of giant beings with diarrhea?
Lee's Dungarees in their "Don't flinch." campaign had the "90-foot (27 meters) Babe" Natalia Adarvez walking through a city, stepping on a Taxi, ripping power lines, towards a high-rise (or so it seems for the normal-sized peeps) where she picks out the window of a nice young man (the size of her finger) and gives him her phone number. Written on a billboard. With a broom. He, wearing Lee's Dungarees, doesn't flinch.
In an Italian commercial for Puma shoes a giant woman is rampaging through a city. She stomps around, smashes some cars and then eats a guy. A soccer player manages to woo her. She quits her rampage and gives him a kiss.

Anime & Manga

Attack on Titan: This show could be called Attack Of The Fifty-Foot Whatever: The Series, to put it simply. True to form, the typical Titan is a humanoid creature about 50 feet tall, being described in the series as 15 meters. Some can grow to be hundreds of feet tall and there are several smaller variations, though even the "tiniest" Titan will still be about 9 feet tall (3 meters). The largest one in size is the Colossal Titan, standing at 60 meters (200 feet). At least until the Founding Titan is introduced; it's large enough for the Colossal Titan to stand on its spine.
The first opening for Bakemonogatari's anime adaptation features Hitagi as a giant whose footsteps can take up city intersections. This has nothing to do with her arc.
Dante in Black Clover can use his Body Magic to turn into a giant, musclebound being with enough physical strength to obliterate the ground with a punch and send the resulting countless debris flying with an arm swing.
Bleach: Once Yammy Llargo releases his Zanpakuto, Ira, he turns into a kaiju-sized behemoth. If he gets particularly angry, he can grow even larger, becoming truly titanic in size.
Bokurano has a group of 15 kids pilot a 500 meters tall robot... against other 500 meters tall robots... in a tournament where the fates of little over 32000 universes are at stake.
The anime of Cardcaptor Sakura featured this with (what else?) the Big Card, whose most malign effect was visited upon a cat (it seemed perfectly content at schoolbus-size.) However, the Big Card was needed in that same episode to fight the giant dragon, which Sakura's friend was describing in the book form of the Create card, and which was preparing to attack Toemeda. Sakura grew to giant size to fight the dragon, and, miraculously, no one noticed.
Though not all measure up to Fifty feet, the Awakened Beings of Claymore are all fairly massive, the smallest standing at least 18-20 feet.
The Ecchi comedy Colorful. In one episode, there is a movie about a giant man with a camera. He shrinks back to normal when he spots a panty shot. In a later episode, there's a 50 foot high school girl.
One of 00 7's abilities in Cyborg 009, though he only used it once when he and other cyborgs were under attack of cyborg animals.
Most of the Akuma in D.Gray-Man are roughly human-sized, but when a ton of level 3s are combined, they turn into a skyscraper-sized black giant of death referred to as a level 3.5. Naturally, one of them wound up fighting General Tiedoll, who turned his Innocence into a wooden mecha to fight it.
The kraken from Delicious in Dungeon is basically a house sized squid. It's even prepared and eaten like one.
Digimon is replete with examples of this, with several of the good guy and Big Bad title creatures taking on titanic proportions at one time or another.
- Special mention has to be made to the stars of Episode 50 of Digimon Adventure: (2020). Holydramon, Goddramon and Milleniumon are large enough that one of the latter's claws dwarfs mountains and makes WarGreymon and MetalGarurumon (themselves now at the size of your typical kaiju) look like ants, and then there's ZeedMilleniumon, who makes the aforementioned Holydramon and Goddramon look microscopic in comparison.
Dragon Ball Z:
- Piccolo and a one time villain Namekian from one of the movies, Slug, have displayed the ability to make themselves grow to gigantic sizes. Piccolo completely forgets about this power until Krillin reminds him in Dragon Ball Super: Super Hero.
- Prior to those two, we had Goku, who turned into a gigantic destructive monkey known as an "Oozaru" when looking at a full moon. This is later revealed to be an inate trait for all Saiyans and, as seen with Vegeta and Dragon Ball GT's Baby Vegeta, they can be tamed, turning them into gigantic destructive intellegent monkies.
Fairy Tail: Lullaby was huge in the manga. He's noticeably even larger in the anime.

"I can't believe you made yourself a bigger target. You really thought bigger would be better?"
In Green Worldz plants have overtaken the land and oxygen levels have skyrocketed, causing bugs to grow giant as well, since insect body size depends on the amount of oxygen in the air.
Various Gundam series usually feature extremely large robots, that dwarf the "normal" mecha. Funny enough, those larger mecha are typically stated to be 40 meters by Word of God, while Gundams are 18 meters (normally), but the large mecha are actually at least 4 times bigger than the protagonist's, making it just as much a case of Sci-Fi Writers Have No Sense of Scale.
- Mobile Suit Gundam, the original, introduced this with Big Zam, a huge cannon with legs.
- Mobile Suit Zeta Gundam had Psyco Gundam, a much bigger version of Gundam, painted black.
- Mobile Suit Gundam ZZ had the return of the Psyco Gundam and the Psyco Gundam Mark II.
- Mobile Suit Gundam Unicorn has a huge Zeong-like armor for Full Frontal's Mobile Suit. That armor's fist was just as big as Unicorn itself!
- Mobile Suit Gundam SEED Destiny introduced the Destroy Gundams, expies of Big Zam and Psyco Gundam combined.
- Mobile Suit Gundam 00 had several. Ali's Agrissa during the battle in the Taklamakan Desert, the Alvatore from the season 1 finale, the Trilobyte from Season 2, and a few others...
- Gundam Build Fighters had a scenario that actually made sense in-series (and wouldn't be physically improbable outside the series either). Halfway through the show, the normal 1/144 sized Gunpla are facing... a 1/48 scale Zaku, which turns out to be surprisingly tough for a Zaku. All of those Gunpla appearing in the show are real-life toys produced and sold by Bandai, including the 1/48 scale Zaku.
- Mobile Suit Gundam: Iron-Blooded Orphans had the Graze Ein in the first season, which was somewhat of a downplayed example, since it's only 22.1 meters big, whereas the other mecha are around normal size. Gets played straight with the Hashmal in Season 2, however, which is more akin to the size of the aforementioned Psyco Gundam.
In one damnation sequence from Hell Girl, both Enma Ai and Kikuri are super-sized. They're mocking the victim's desire to be a "big shot".
In Himechan No Ribon, Himeko acquires the ability to increase or decrease the size of things. She's able to transform herself into a giantess, but since she is trying to keep things secret, she seldom uses the growth ability.
The fifth Is It Wrong to Try to Pick Up Girls in a Dungeon? novel has an aptly named Goliath as its boss. It falls onto the ceiling of the 18th floor, and attacks the adventurers.
Jungle de Ikou! ends with Mii turning into a giantess to stop Ongo from destroying the world.
One episode of Kimba the White Lion is titled "The Gigantic Grasshopper".
This happened to Kankichi Ryotsu in one chapter and anime episode of Kochikame.

Lyrical Nanoha:
- Magical Girl Lyrical Nanoha also had an episode where the adorable little kitten was enlarged into an adorable giant kitten by the collectible Plot Coupon. A previous episode had a cute puppy getting enlarged as well, though that one's giant form was less cute and more demonic-looking.
- Chapter 48 of Magical Girl Lyrical Nanoha ViVid reveals that one of Fabian's devils could grow to the size of a small house.
Macross:
- Super Dimension Fortress Macross: The point of the Humongous Mecha is that the Earth forces knew the Zentraedi aliens coming to claim the SDF-1 would fall under this trope, and built them so they could fight the invaders at their own scale.
  - You don't really get the sense of scale until you see Breetai and his minions (none of whom are wearing their Powered Armor) fighting against Hikaru and Max... while the latter two are still in their Valkyries.
  - ... and Breetai's still taller than them! He's big even for a Zentraedi, though (if the average 30-feet-tall Zentraedi warrior is equivalent to a 6' human, Breetai's easily 6'7" to 7' proportionally); most other Zentradi are as big or slightly smaller than a full Battroid-form Valkyrie.
- In Macross Frontier, the trope is gleefully subverted as the Zentraedi have become part of accepted human society... and many of them still spend most of their times as 10-meter-tall people who still do simple stuff like farming. A highlight is two humans hanging out with a Zentraedi at a mixed-size mall... and in order to be at eye-level with her, the humans are on a third-story balcony.
- That said, full-sized Zentraedi seem to be fairly rare in colony fleets outside of the Macross Frontier fleet, as the majority of "cultured" Zentraedi seem to prefer shrinking themselves to human-size. The Macross 7 fleet had no full-sized Zentraedi other than Exedol, and the Zentraedi-exclusive Macross 5 fleet had none either. "Cultured" Zentraedi living at full size are apparently so rare that even Mylene Jenius, half-Zentraedi herself, had never met one and was shocked to do so.
  - There's also Mylene's sister Emilia, who must have macronised herself only recently, since Mylene was surprised to see her at full size when they met up again.
  - Which makes sense, since by being probably dozens of times a normal human's mass, full-sized Zentraedi would use dozens of times a normal human's resources in food, air, and space, which are rather valuable commodities in a self-contained environment like say... a space ship (let's not even get into why the Protoculture thought making their space-faring warrior race over-sized was a good idea to begin with...).
  - Background material also indicates that full-sized Zentraedi are not permitted to set foot on Earth after the first series, though "micronized" Zentraedi are perfectly fine. Apparently Earth got fed up with Zentraedi revolts after a while and wanted an easier time of keeping dissidents under control.
- Besides the Zentraedi, Macross Frontier also has the Vajra, who are basically Big Creepy-Crawlies IN SPACE!, with the largest ones bigger than most capital ships.
Volume 2 of Magical Girl Apocalypse has a Kaiju-sized magical girl with an upside-down head. In its appearance, it crushes a platoon of soldiers under its foot, downs some helicopters, and ends up destroying the mall that the protagonists are hiding in.
In episode 10 of Magical Shopping Arcade Abenobashi, a paper doll transforms into a giant teddy bear, which rampages throughout the fairy tale land. After a failed attempt to trap it in a magical barrier, it grows so big that its head leaves the atmosphere.

One episode of Midnight Horror School had Ampoo turn Piranin into a giant so he can become a terrifying sea monster.
Most of the dragons in Miss Kobayashi's Dragon Maid have true forms that are a few stories tall. Lucoa on the other hand is much, much larger (as in "several times bigger than a mountain" large), with even her eyes individually dwarfing Tohru's entire body.
One episode of Mon Colle Knights is specifically titled "Attack of the 50-Foot Lovestar" (for the dub anyway), and has the normally fist-sized Lovestar grow huge after drinking some water near a farming village.
In one chapter of Monster Musume, Kimihito encounters a rampaging dryad who's grown to an enormous size because of experimental fertilizer waste being dumped in her forest. Suu ends up falling into it and growing to a similar size, resulting in a very odd Kaiju battle.
Some of the Mushishi creatures-of-the-episode were quite large. The dying swamp, in particular.
My Bride is a Mermaid has this happen to Nagasumi, averting Magic Pants in the process.
My-Otome essentially qualifies for this in the late episodes, when Nina Wong uses the Harmonium and grows into a several-hundred-foot-tall shadowy version of herself. The physical nature of the transformation/manifestation is debatable, but cities get crushed, hinting at plenty of mass.
Naruto:
- The very first scene of the series is of a giant Nine Tailed Demon Fox attacking the Hidden Leaf Village then being magically sealed inside the title character. We are later introduced to the other 8 Bijuu demons, all of which are gigantic in their own right. And then we're introduced to the Tailed Beast's progenitor, the 10-Tails, which is at least three times the size of the other Tailed Beasts in its first form alone, and gets even bigger as it advances through its subsequent forms.
- Summoning Jutsu allows you to call forth giant beasts to attack enemies on your behalf, providing you have a contract with them. The actual size varies both from species to species and creature to creature, from normal sized dogs to "Boss" Snakes, Toads and Slugs that tower over tall buildings.
- One of the Akimichi clan's abilities is the ability to grow to an incredible height. It's firstly demonstrated by Chouji's father Chouza, who turns into a giant and stomps on enemy ninja, and then by Chouji himself in the fight against Jirobo where he becomes so huge, his body occupies a clearing.
- The purpose of Pain's Animal Path is to invoke this trope. Literally: he summons giant monsters to fight for him.

The End of Evangelion takes this trope to the Logical Extreme: Attack Of The 1200 KILOMETER Naked Girl!
Episode 4 of Oku-sama wa Mahou Shoujo features a giant teddy bear walking through the town. It's soon revealed that it was only a model of the town in Cruje's room.
One Piece:
- This is the essence of Luffy's Gear Third. Although he hasn't turned into a full-sized giant as of yet, he can expand parts of his body to the point of outclassing regular giants — who themselves measure at least 60 meters.
- In the Marineford arc, the Giant Squad on the Marines' side and Oars Jr. on the Pirates' definitely counts. Fleet Admiral Sengoku is also this when he reveals his Zoan Devil Fruit powers.
- In the Dressrosa arc, Pica is an already naturally towering man, but thanks to his Devil Fruit that allows him to assimilate and merge with stone, he can become truly gigantic.
- Filler character Lily Enstomach is a giant, but she has eaten a Devil Fruit that allows her to shrink in size at will, so the trope is naturally invoked when she returns to her true size.
- Kaido's Devil Fruit allows him to turn into a truly massive Azure Dragon, one big enough to dwarf a small town.
- After Luffy awakens his Devil Fruit and gains Gear Fifth, he gains small-scale Reality Warper powers, which amongst other things allow him to actually become a giant.
The final battle of Overman King Gainer features an Overman-sized Overdevil-controlled Gainer.
In one episode of Panty & Stocking with Garterbelt, Stocking turns into a giant as a result of some magically fattening sweets.

A couple episodes of Pokémon: The Series had the cast encountering Pokémon the size of buildings.
- Ash's Treecko and a Gulpin becoming giant due to some Applied Phlebotinum.
- An inexplicably gargantuan Claydol appears as a Sealed Evil in a Can and goes on a rampage when Team Rocket frees it.
- A scientist's experimental treats cause a Caterpie that ingests them to turn gigantic, subsequently re-enacting a parody of Mothra (complete with metamorphosing into a Butterfree). Team Rocket uses the same treats on Jesse's Dustox and James' Cacnea.
- Another time involved an amusement park island with Pokémon-shaped automatons that were several times the natural size of the critters they emulated - and the cast was stuck ON the island for the duration of the episode.
- The giant tribal marked Alakazam and Gengar, and the giant similarly marked Jigglypuff Ash and Co. have to summon to sing them back into containment.
- The episode where a Tentacruel grows to a huge size and destroys a city. Misty talks it down and convinces him and his normal-sized kind to go back into the ocean.
- An episode set in Galar (where this happens frequently) has Ash's Pikachu unintentionally Gigantamax to combat a Gigantamax Drednaw.
In Pokémon Golden Boys, Gold encounters a giant Sudowoodo.
In Ranma ½, the forest of Ryugenzawa is home to a variety of exotic animals, such as koalas and platypuses, who have grown to titanic size (think "rabbits the size of grizzlies" and "flying squirrels the size of fighter jets") due to the magical properties of the Water of Life —itself a product of the magical moss that grows on the snout of the mountain-sized Yamata No Orochi.
Chiri from Sayonara, Zetsubou-Sensei grows into a giant in one episode to fight an alien invasion in a parody of the Neon Genesis Evangelion movie. There's also a Giantess panty shot, but only because it was relevant to the episode's theme.
Episode 30 of Sgt. Frog introduced the Flash Spoon, a device that could make its user grow to enormous size. In the first half of episode 57, Keroro uses it to one-up Viper the Elder when the villain grows to giant size in a last-ditch effort at beating the Keroro Platoon. In the second half of the episode, a trip to the Nishizawa Group's private island (while waiting for the effects of the Flash Spoon on Keroro to wear off) results in a cuttlefish, a crab, and a turtle being turned into giant monsters by the spoon, while the rest of the cast also grows in an effort to stop them (except Dororo, who doesn't get his hands on the Flash Spoon until the batteries have run out).
- The same thing happened in the dub, only it was called SpoonWow (made in Germany, you know the Germans always make good stuff).
Mana Eimiya, the titular Super Dreadnought Girl 4946, stands at 49M and 46CM and fights alien monsters of comparable size.
- Then at the end, she enters a Super Mode where she grows to the size of 4946M.
Let's not forget Tengen Toppa Gurren Lagann. It went from the 50 ft tall variety in the beginning all the way to the size of a galaxy! What can you do when your opponent is also that size? Obviously you throw galaxies at them. Super Tengen Toppa Gurren-Lagann is stated to be roughly 3,5% of the size of the observable universe. Its only weapon? A huge energy-drill that's 10 times bigger than the thing itself. The Anti-Spiral counters by growing to 3,5% the size of the observable universe and wielding a 10 times as big drill... Yes, the final battle has over 77% of the observable universe occupied by mecha and their weapons!
UG♥Ultimate Girls: Three High School girls grow to 30 meter stature, then fight the monster of the week. Lather, rinse, repeat. However, subverting the Magic Pants trope is the whole point of the show.

It shrinks back to a normal size after Somnambula and the serpent's other victims escape from its gut and take the stone with them.
The National Lampoon did a comic-book parody of the genre called "Attack of the Sizeable Beasts", where a well-intentioned scientist's growth-hormone test animals get loose. Not monstrously big, just...bigger than normal. A really large raccoon falls out of a tree and dents a car, a remarkably large bird flies off with a baby's sweater, that sort of thing. They don't wreak havoc so much as a low level of annoyance.
Recurring villain Zoster of Paperinik New Adventures in his last appearance stole Xadhoom's powers and use them to become as big as the SUN. How many foot are those? Fortunately it was all a plan of Xadhoom that she created before dying. In fact it was the last appearance of Zoster because the experiment killed him.

In Turma da Mônica e Garfield: O Lápis Mágico, Captain Fray summons a towering monster made entirely out of lasagna to wreak havoc across both Lemon Tree Street and Muncie, Indiana.
Dr. Manhattan from Watchmen can boost his size to become bigger. Much bigger. Actually semi-justified in Manhattan's case; he rebuilt a body for himself after the accident, so the fact that he made it human-sized is largely nostalgia/convenience.
Played tragically in Issue 4 of the Weird Science comic anthology. A scientist helps a short man get taller with an experimental procedure on his hormone glands. Unfortunately, his body doesn't respond to the treatment to stop it, and he keeps growing until he becomes a giant. Becoming incapable of getting any work and getting negative press from all the food it takes to feed him he's ultimately hounded by the military until he's bombed to death trying to escape in the ocean.

Zombo: After Obmoz gains "the power of a million Zombos" thanks to Zombo's Mad Scientist creator, he becomes a gigantic zombie who proceeds to rampage around the city killing anything in sight.

Comic Strips

A recurring theme in Calvin and Hobbes:
- One strip has Calvin imagining he drinks a magic elixir and grows to over 300 feet. He proceeds to rampage through an imaginary town. His mom is not amused when Calvin asks for replacements for the toy cars that were lost in the rampage.
- He also built several castles in his sandbox and said they were downtown Tokyo. Then he stomped across them with a growl and said he was Godzilla.
- One winter day, he built about fifty tiny, foot-tall snowmen... at the base of a hill... and then went up the hill with his toboggan.
  Calvin: For the townsfolk below, the day began like any other day...
- And, of course, the many strips involving a rampaging carnosaur qualify.
- In one of Calvin's Imagine Spots, he becomes "the size of a bug to a bug" and a giant bug starts trying to step on him. The trope is then inverted when a giant frog saves his life by catching and eating the bug.
A number of The Far Side strips feature giant monsters, including one skyscraper-sized mailman and a group of dogs rallying to save the city.
Garfield: One of the announced movies on TV is "Attack of the 50-Foot Calzone".

Fan Works

Some members of FanFiction.Net are trying to turn this into Memetic Mutation, but it's not catching on since no one can remember the name. Some other members are thinking about writing DE:HOTSTC:TBNDW:TAOFTSFKFBTS because this trope can (and does) get played for Rule of Funny a lot in the Digimon fandom.

In With Strings Attached, the four are at one point shrunk to six inches high.

Whether he can really grow that tall remains to be seen.
In The Keys Stand Alone: The Soft World, the first person the four encounter is the Magic Taxman.

The Secret Return of Alex Mack sees "Terawatt" fight a 200-foot (and still growing) tarantula, and later a 90-foot woman affected by an unknown mutagen. Being able to fly is quite helpful in both fights. Makes sense as it's a crossover with (among other things) lots of B-movies.

Sinbad: Legend of the Seven Seas has Eris, Goddess of Chaos. She's a little different in that she intentionally switches between being normal size and 50 foot size with no problem.

The ABCs of Death: In the "W" segment, the city is attacked by a giant walrus that fires laser beams from its eyes.
Alligator featured a pet baby alligator flushed down a sewer where it grows to massive dimensions eating test animals illegally dumped by a chemical company. Well-done comic horror, and written by John Sayles, yet.
Arachnid was about a bunch of people on a tropical island getting attacked by a giant spider from outer space and all its mutant babies. It spawned giant centipedes, giant ticks, another spider, and at the very end, what looked like a grasshopper.
The trope gets its name from Attack of the 50-Foot Woman, a 1958 B-Movie about a wealthy socialite who has a close encounter with a giant alien, grows to the titular height, and has her revenge on her philandering husband. Known for its not-so-special effects and famous poster, it has become a cult classic. Remade as a Made-for-TV Movie for HBO starring Daryl Hannah.
- Interestingly, the famous poster used as the page image actually depicts the woman as around 200 feet tall. Perhaps she just wasn't big enough for the poster artist?
- Attack of the 60-foot Centerfold. And, 17 years later...
- Attack of the 50-foot Cheerleader. Both featuring the producing talents (uncredited in the first) of the legendary Roger Corman, with all that that implies.

Scientist examining giant tomato: "Gentlemen, it's worse than we thought. This, God help us, is a cherry tomato."
The Blob: One of the key features of the Blob is that every person it consumes adds to its own biomass. When it is discovered it's about the size of a grown man's fist, but by the climax it's eaten enough people to become building-sized. Potentially, it could envelop the whole planet.
Seen in Cloverfield, which featured a monster that can only be described as a 400-foot whatever. Seriously, look◊ at the thing!.

The little-remembered Japanese monster movie from the makers of Godzilla, Frankenstein Conquers the World, featured a child who emerges from the atomic bombing of Hiroshima, grown from the irradiated heart of Frankenstein's monster, and turns into a giant wild-man who fights a giant lizard-beast.

  - That was actually an ending filmed for the American version, but it wasn't used. Both versions end with Franken-boy and Baragon falling into the earth.
Godzilla, the skyscraper-sized dinosaur is this. At 350 feet, a total length of 550 feet 2 inches long, and 90,000 tons, the 2014 version is the biggest and heaviest Godzilla of all time. Until he was one-upped by Shin Godzilla who is 118.5 meters tall, a full 10 meters taller than his Legendary counterpart and much meaner, uglier, and in a sense more pitiable.
Ghostbusters:
- An entertaining example comes from the climax of Ghostbusters (1984), when Big Bad Gozer makes the Busters choose a form for the monster it will summon to destroy New York City. While the other Ghostbusters try to empty their minds, Ray tries to think of the most harmless thing he can imagine: the mascot for Stay-Puft Marshmallows. Which results in a giant, grinning, sailor-hat wearing humanoid monster made of marshmallows stomping through Manhattan.
- They turn it right around in Ghostbusters II, when the Ghostbusters themselves using Jackie Wilson's "Higher and Higher" to animate the Statue of Liberty, and use it to break into the art museum to stop Vigo the Carpathian from coming back to life.
Giant monsters were the stock in trade of director Bert I. Gordon, better known as Mr. B.I.G. He directed many of the 1950s radioactive monster movies, including The Amazing Colossal Man, Earth vs. the Spider, and Beginning of the End (about giant grasshoppers). In the 1970s he did two more films in this vein, Empire of the Ants and The Food of the Gods very loosely based on works by H. G. Wells.
- The Amazing Colossal Man (mentioned above) might just as well be called Attack of the 60-Foot Man, and it came out in 1957, the year before the trope-namer.

Near the end of the movie, Adam goes to Las Vegas and gets even bigger, and at one point, two Japanese tourists briefly appear:
Female Japanese tourist: Gojira!
Male Japanese tourist: No!... Big baby!
The Jungle Book (2016) has King Louie. Instead of being a orangutan he's an gigantopithecus blacki, which basically amounts to being a giant orangutan.

In one scene from Misfit Heights, a female tenant is seen running in terror, when a nearby door opens up. A massive hand grabs her, pulling her towards the door, and the massive face that's behind it.
A heroic example turns up in the climax of The Muppet Movie. Doc Hopper has just ordered his hired goons to kill Kermit the Frog and company, and as they prepare to do so a rumbling is heard...a previous scene had set up that Dr. Bunsen Honeydew had created "Insta-Grow Pills" that have "sadly, temporary" effects. It turns out that Animal has taken some of them, and when he bursts out of one of the buildings and roars, the villains flee and the good guys cheer.
Night of the Lepus features Giant Killer Bunny Rabbits. It is not intended as a comedy. It is, however, inspired by the Australian satire The Year of the Angry Rabbit by Russell Braddon.

In Pacific Rim, after Kaiju emerge from the Pacific hellbent on destroying humanity, giant robots are built to combat them.

Alice in Wonderland, wherein it is Portal cakes, tonics, and pieces of mushroom that cause Alice's vast changes in size - though these changes are irregular: when Alice first expands in the White Rabbit's house, she appears to be as normally proportioned as ever, but when she eats part of the Caterpillar's mushroom, her neck is described as having grown serpentine and winding compared to the rest of her.
In the apocryphal work The Ascension of Moses, the angels Af, which means "Anger", and Hemah, which means "Wrath", stood 500 parsangs in height and forged out of black and red chains and made to enforce His will.

Sammael is described as begin covered from head to toe in glaring eyes and his job is to "[take] the soul away from man". The trio aren't exactly "nice" or "good" but they have a job to and they do it well.

- When the movies in Moving Pictures break the barrier between reality and the Dungeon Dimensions, a giant copy of the lead actress, Ginger, steps out from the screen.

- At the end of Unseen Academicals, reports arrive of a seventy-foot monster chicken rampaging through Pseudopolis.

Wouldn't a bowel movement evacuate a city?)

Even Doctor Who hasn't been able to resist this trope:
- Classic Who had "Robot" where The Brigadier's attempt to use an experimental disintegration gun on the eponymous robot results in it growing to gigantic size.

- In "The Angels Take Manhattan," the Statue of Liberty turns out to be an alien statue called a Weeping Angel and naturally, it is gigantic. Oddly, since the Angels use stealth as their greatest strength, it isn't as threatening compared to the other Angels and is just background. It's also portrayed a lot smaller than the real thing.
  Rory: I always wanted to see the Statue of Liberty. I guess she got impatient.
The Electric Company: Do not bother this tiny person. Or he will send his big brother after you!

- Kamen Rider Arc is the largest Kamen Rider to date at 3.2m tall, without use of CGI!
- Kamen Rider J is a heroic version of this trope, able to grow to building-size in order to fight Fog Mother
  - Doras gains this ability after merging with Fog Mother in the ZO/J Crossover movie.
- Parodied in Kamen Rider Decade. When Momotaros appears via Final Form Ride, the camera took an angle that made it look like Momotaros had become giant. Decade quickly shattered that perception.
  - Played straight in Decade's first movie, All Riders vs. Dai-Shocker, with King Dark, J, and Jumbo Complete Decade.
The 1970s series Land of the Giants dealt with a bunch of people from earth whose airship somehow crossed over to another world where the people, animals and things from that world are all 12 times normal size.(One example: a dial telephone on a desk is about 4 feet tall.)
The crew of Lexx fought enormous alien replicas of human women in two episodes.
Massive Monster Mayhem is a game show where one of the 3 pre-teen contestants grows massive size to combat one of Master Mayhem's Monsters, via finding power pods and activate the Megalaser to defeat the monster. Master Mayhem can teleport his monsters to Earth, Mega-Sized, by pressing the green button.
In Monster Warriors, Klaus Von Steinhauer specialised in giant monster movies, and now that he has access to the Monster maker, these make up the majority of the beasts he unleashes on Capital City. Aside from the Big Creepy-Crawlies (listed under that trope) other giant creatures he created include: lobsters ("The Giant Lobster Invasion"); a giant Muck Monster ("Revenge of the Mud Maniac"); a sea cucumber ( "Voyage to the Bottom of the Sea Cucumber"); frogs ("Ribbit" and "Ribbit 2: Froggy's Revenge"); a jellyfish ("Beast from Below"); vampire bats (Megabatua"); a giant robot ("Astrosaurus vs. Gigantobeast"); a rat ("Ratblaster"); penguins ("Penguins"); and gnomes ("Gnome for the Holidays").
In the "Killer Cars" sketch on Monty Python's Flying Circus, the cars are eventually gotten rid of "by the miracle of atomic mutation" — that is, they're chased away by a giant cat walking on its hindlegs.
The Mr. Potato Head Show: In one episode, Dr. Fruitcake grows to enormous proportions after eating radioactive sludge. In another episode, Dr. Fruitcake ends up in a parallel universe where he's chased by a giant, carnivorous Mr. Potato Head.
A common type of movie featured in Mystery Science Theater 3000. Besides the Bert I. Gordon films above, there was The Giant Gila Monster, The Black Scorpion, The Crawling Eye, and many, many more. In the episode featuring Earth vs. the Spider, Crow decides to write his own giant monster movie, Earth vs. Soup.
The New Avengers: The threat in "Gnaws" is a sewer rat mutated to monstrous size by an undiluted experimental growth formula spilled down the drain.
Odd Squad:
- At the end of "Happily Ever Odd", Donnie, serving as his brother's best man at his wedding, is revealed to have eaten five of Oona's lab carrots, and as a result, he has grown tall enough to where he can't even stand up properly and has to crane his head forward in order to fit.
- One of the superpowers Orson has is the ability to grow into a giant, although he doesn't age up and still remains a baby. "Saving Agent Orson" shows this power in action when Oprah recounts a story to Xavier and Xena in order to convince them not to fire Orson. When everyone gives up on trying to save Odd Squad from two rampaging Hydraclops, he refuses to do so and reveals that he is a Sizeshifter. It's such a sudden turn of events that it manages to leave both Oona and Oprah — who had also given up and were about to abandon Precinct 13579 — in a wordless shock as he towers over them. With this power, he managed to defeat both Hydraclops and save the town (and the precinct) from destruction.
- Blobs, a species of odd creature, are usually small when they are infants, and can be both red and blue. However, as "Running on Empty" shows, they can grow to be enormous, about half the size of Big Ben.
Power Rangers / Super Sentai:
- The climactic scene in almost every episode ever made. The villain uses some form of Applied Phlebotinum to make the monster grow which usually necessitates the use of a Humongous Mecha in order to take the monster down once and for all.
- The final episode of Power Rangers Zeo had the Rangers grow as well as the villains.
- In Uchuu Sentai Kyuranger, Koguma Sky Blue, whose powers are based on the Ursa Minor constellation (and is also Just a Kid) recieves a powerup based on Ursa Major that makes him do this. Though it does not mean that he's the same size as the Humongous Mecha, heck no. That mecha easily breaks through the atmosphere.
Sir Arthur Conan Doyle's The Lost World not only featured dinosaurs but also giant sized versions of normal creatures (such as bees) for no adequately explained reason.
Parodied on Taskmaster. In the first episode of Series 10, the contestants are given the task of making the largest thing they can find appear to vanish without using any kind of editing trickery (i.e. without cutting from a shot of the object present to a shot where the object as been removed). Johnny Vegas decides to interpret this through a combination of this trope and political commentary on Jeremy Corbyn's decisive defeat in the 2019 British general election, by staging a "400ft" taxidermied mutant socialist chicken, unleashed by Corbyn upon his political enemies, attacking a paper version of Westminster.
3-2-1 Contact subverts this trope with a very convincing explanation of why a giant insect ala Them! is physically impossible.
The Ultra Series made its enormous success through bringing the giant monster battles of films like Godzilla to the small screen. In nearly every episode, humans transform into enormous alien heroes to battle kaiju or alien invaders who have turned themselves gigantic. In fact, a fair fraction of Toku series involve something small growing to meet the height of something already quite large. Then they fight.

Music Videos

For some reason giant, beautiful women guest starring in music videos is really popular. However for the musicians in these videos the encounters with these giant ladies usually end unpleasantly.
- Averted in Go West's video, "Call Me", where she doesn't eat them, but literally gives the two singing leads the brush off!
Bubble Butt features "Buttzilla," a Giant Woman who can fly, Summon Backup Dancers, and produce prehensile bicycle pumps from her mouth that she uses to inflate women's butts. She also uses the hose to grab a backup dancer and eat her alive.
In The Cars video, '"You Might Think"', lead singer Rick O'Casek imitates King Kong in the middle of it, grabbing the girl he's after.
- And speaking of the titular giant ape, in near-end of Sheena Easton's video, "Long Distance Love Affair", you can pretty much guess who shows up to rescue her from Dracula, the Wolf-Man, Frankenstein, and the Crawling Hand.
The music video for "Miserable" by Lit has the band playing on a giant Pamela Anderson to entertain her. A few of the places they play include her butt, her legs, her high heeled shoes, and her face. She eats them.
The video for Quiet Riot's "Mama Weer All Crazee Now" ends with a giant version of Kevin Dubrow emerging from a movie screen and wreaking havoc.
In the Czech band Lucie's music video for "Panic" features a gigantic woman in a red dress. For most of the video the lead singer is standing in her hand serenading her. At the end of the video the lead singer slips a ring on the giantess' finger. Unfortunately for him the giant woman then decides he looks tasty and eats him alive.
The music video for "Love Machine" by Morning Musume does this to Mari Yaguchi, who happened to be the shortest member of the group at the time. The video for "Kare to Issho ni Omise ga Shitai" also had this with Risa Niigaki fighting a Godzilla expy, apparently with The Power of Love.

Tabletop Games

Changeling: The Lost: One of the Kiths available to Ogre characters gives you this as its special power. Depending on how powerful you are and how big you are already, you grow to anything from the size of a gorilla to bigger than an SUV. Coincidentally, this Kith is called the Gargantuan.
The 3rd Edition of Dungeons & Dragons has a supplement called the Epic Level Handbook. Aside from monsters that are tremendously powerful, a disproportionate number of the monsters are also tremendously big, such as the Flesh, Stone, and Iron Colossi (super-sized versions of the more common flesh, stone, and iron golems) and the devastation vermin (really big bugs). In Monster Manual II, there is also a template to take a tiny or smaller creature and make it bigger than a house.
- Hence ... The Titanic Toad!
- In the older Spelljammer setting, there were Giant Space Hamsters — roughly the size of bears — bred from regular hamsters by Krynnish Tinker Gnomes. And then they bred some of them back to regular hamster size, creating Miniature Giant Space Hamsters, because Tinker Gnomes are weird. Famously, Boo of Baldur's Gate may or may not actually be a Miniature Giant Space Hamster.
  - And then we get into the really out there variations, like the Sabertooth Giant Space Hamster or the Flying Carnivorous Giant Space Hamster.
  - And the Firebreathing Phase Doppleganger Giant Space Hamster.
- The Classic D&D rules and its Known World setting have a long history with this trope, from the corpse-formed colossus in X2: Castle Amber to creatures such as the earthquake beetle. And that's not even counting the Immortals boxed set, which introduced critters like the draeden, one of which has long been mistaken for a layer of the Abyss.
Exalted has some of its behemoths, and any Lunar with Emperor Ox Expansion. One character, Leviathan, has spent the past two millennia as an orca roughly the size of a small island.
- Many of the Shintai charms, native to the Green Sun Princes, turns its user into a 50-feet version of their patrons, themselves are hundreds of feet scary things. For example, you can turn into massive humanoid sandstorm, massive tentacular sea monster, massive green radioactive star... And if you go Devil-Tiger route, you can have Attack of the 50 Feet You.
Gammarauders has the bioborgs, giant cyborg creatures that can be fitted with various weapons. There are also conventional forces (in the form of aircraft, tanks, and infantry), which are collectively referred to by players (and the official manual) as popcorn. They can make a difference in a battle between bioborgs ... but not much of one.
Magic: The Gathering has Giant Growth, one of the most commonly reprinted cards of the game.
- Spoofed in the (deliberately silly and not tournament-legal) Unglued expansion set with the B.F.M. (Big Furry Monster), a creature so big it doesn't even fit onto a single card.
- The world shard of Naya, the home of Godsire, from Shards of Alara is home to enormous creatures known as "gargantuans", which are worshiped by the local elves and humans. It has a "big creatures matter" mechanic, there was even one card that would win you the game if you had a 20-power creature after you untapped at the beginning of your turn, as well as speeding your creatures on a path to such a size. The Tarkirian clan known as the Temur Frontier has a similar effect, although it's tuned down to just 4 power instead of 5 and doesn't seem to consist largely of adding keywords to giant monsters.
- Even more with the release of Rise of the Eldrazi, which feature some of the largest creatures EVER printed in the history of the game.
- The "Timmy" demographic in Magic: The Gathering is defined as caring first and foremost about massive creatures that can slam the opponent (or, in a broader sense, any spell with a huge, sweeping effect), and Magic sure has no shortage. The classic "biggest and baddest" is Leviathan; other notables include the devastating Dragon Tyrant, the unspeakably large Denizen of the Deep, and the majestic Godsire. The single biggest, baddest, most monstrous monster in the whole game, though? The dread goddess Marit Lage, who is so powerful she can't even be summoned by normal means.
Warhammer 40,000 seems to have a fondness for using "battle tank" as a standard size for wildlife, and Tyranids revel in this trope with their heavier creatures, especially the Bio-Titans.
Warhammer: Giant monsters are not uncommon in certain armies, and several resemble supersized versions of common animals.
- Giant Spiders are common sights in the forests of the Empire and goblin warbands. Most grow to around the size of a horse, but the Arachnarok Spider of the deepest forests can comfortably outsize a house and makes for a devastating war animal in greenskin horde.
- The skaven of Clan Moulder specialize in breeding gigantic, ferocious monsters to sell to other clans as war monsters. One of their crowning achievements, the Brood Horror, is a huge, hairless rat larger than a tank.
- Warhammer Fantasy Roleplay: Extreme gigantism is one of the most common mutations caused by Chaos on normal animals; while most cases aren't quite extreme enough for this trope (giant rats and spiders, for instance, are "only" the size of a wolf), others, like fen worms (common marsh snakes turned into 20- to 30-foot long monsters), certainly are.
Yu-Gi-Oh! has a variety of monsters that range in appearance and size, and as you can imagine some of them are outright gigantic
- From the Yu-Gi-Oh! anime come the depictions of the Egyptian Gods Obelisk, Slifer, and Ra. By extension, Horahkty is fairly massive too, and Exodia (based on Osiris) is massive as well. Exodia Necross, Exxod Master of the Guard, Exodia Incarnate, and Exodius the Ultimate Forbidden Lord likely rival Exodia in imposing size.
- The Wicked Gods Dreadroot, Avatar, and Eraser are direct opposition to the Egyptian Gods, so they're about the same imposing size. Since Avatar takes the form of the strongest monster on the field; it's only this is mimicking another example of this trope. This is also true for the Sacred Beasts Uria, Raviel, and Hamon, and their fused form, Armityle.
- The Earthbound Immortals were the largest monsters in the franchise bar the Great Leviathan, matching skyscrapers in size. They're mainly massive animals based on the Nazca Lines.
- Thor and Loki are pretty large, but not to much bigger than the average example of this trope. Odin, on the other hand, is so big he towers over the horizon behind the city.
- Supreme King Z-ARC from ARC-V is around the size of the Earthbound Immortals - and his truly bafflingly insane wingspan and tail length add to this.
- The Kaiju archetype uses exactly what it sounds like, Kaiju sized monsters based entirely on Godzilla characters, and as any idea of this would be, most of the monsters range from giant robots to massive fire lizards to three-headed lightning shooting monsters.
- The Alien archetype has Cosmic Horror Gangi'el and Cosmic Fortress Gol'gar, monsters clearly based on Lovecraftian design and depicted as large collections of tentacles and claws. Exactly how large they are isn't certain, but one of them is called a Fortress. The similar Worm archetype has Worm Zero, which is basically the size of a city.
- The absolute king of this trope in Yu-Gi-Oh! is Star Eater. The name says it all.

Theatre

The cover of the original cast recording of Irma La Douce depicts a gigantic Irma towering over Paris.
Royal De Luxe, a French street performance group known for rather enormous puppets.

Theme Parks

When Chessington World of Adventures (near London UK) first opened, one attraction was a dark ride called "The Fifth Dimension", on which the riders were "shrunk" and travelled through a series of scenes of giant domestic items. Needless to say, the riders got "restored" just before the ride ended. (This ride has since been rethemed into "Forbidden Tomb".)
A musical version of Creature from the Black Lagoon at Universal Studios Hollywood features an enormous puppet of the Gillman at the end, made his unnatural size by an accidental application of... ahem... male anatomy enhancers.
In The Simpsons Ride, also at Universal Studios, Maggie wanders into a nuclear reactor and later appears as a giant, serving as something of a Deus ex Machina.

Toys

BIONICLE Rahi Nui is already about 50 feet tall in its standard form (and it also attacks). But it has the power to grow even larger. So large, in fact, that this has once caused its molecules to split, since it couldn't control its density.

Video Games

Unintentionally subverted in Age of Mythology, as the Giants, Frost Giants, Fire Giants and Greek colossuses are only about two or three (four tops) times the size of the human figures. Then you buy the expansion pack and watch and marvel as your enemies get goomba stomped by a giant birdman which took you an hour or so to build.
In Amea, a good number of the bosses are this. Special mention goes to Mish, who was only a small child the last time he was seen.
Asura's Wrath takes this to a RIDICULOUS level, as the final form of the first boss turns to the size of a planet and tries to CRUSH YOU TO DEATH WITH A FINGER THE SIZE OF TENNESSEE!
- Probably the ultimate example of this in both Asura's Wrath and possibly all of gaming is Chakravartin, who's extension of his power is so big his basic projectiles are Planets and Small Stars, he throws suns at you later, and Galaxies are small in comparison to him. He's really , REALLY big.
Attack of the Mutant Camels. To quote from the manual:
The evil alien nasties have invaded the earth - but not in person! They have abducted some camels from earth and used devious genetic engineering to mutate the normally harmless beasts into 90 foot high, laser spitting, neutronium shielded death camels!
Colbear of Battle Bears, who is so huge that you can only see his large legs in the first phase of the boss, and even when he picks you up, you don't even see his entire arms.
The Famicom version of Bokosuka Wars has a rather silly animation on its Game Over screen depicting King Suren and his troops being chased by a giant version of King Ogereth. If the player manages to win, the ending is a reversal of this scene, with a giant Suren chasing after Ogereth and his troops.
The Final Boss of Cho Aniki: Kyuukyoku Muteki Ginga Saikyou Otoko is a 50-foot tall wrestler wearing a Speedo and a Viking helmet, whose attacks include nasal fireballs, Fartillery, and a navel Wave-Motion Gun.
City of Heroes has the 'Giant Monster' enemy class for foes that fall under this trope. Most of them spawn in open areas and are specially coded so that characters of any level can deal substantial damage to them. Some like the Kraken, Eochai and Devouring Earth monsters are simply giant versions of regular mooks, but there's also Lusca the gigantic octopus, Jack In Irons the giant... well, the giant, and one of the ultimate Big Bads of the game; Hamidon- a colossal single-celled organism that takes dozens of players and special tactics to defeat.
- Adamastor the giant zombie, and the Humongous Mecha piloted by U'kon'Grai, Rikti Master at Arms with a name that's one big in-joke^note
In Command & Conquer Red Alert: Counter Strike, there is a secret campaign where you fight giant ants
Almost every single boss in the Contra series is a 50-foot robot or alien.
The game Corruption of Champions has quite a few giants in the game. From smallest to largest are Minverva (8'5"), the Sand Mother (8'6"), Izumi the Oni (9'0"), Corrupted Dridder (10'), and Venus the turtle-girl (bigger than everyone else).
- Shouldra, a ghost you can befriend, has spell that make certain body parts bigger but occasionally she messes up an makes the person she's inhabiting much, much bigger, almost as big as Venus.
In Crush, Crumble, and Chomp!, the player is one of these.
In the Japanese PS2 game The Daibijin or Demolition Girl depending on the version, the player must pilot a helicopter, and in one stage an airplane, against a bikini-clad woman who had been brainwashed and turned into a giant by aliens. Seriously.
Lordran in Dark Souls is littered with dangerous giant beasts, such as wolves, armored boars, and magic-shooting butterflies.
Destroy All Humans!:
- The final chapter of Destroyall Humans 1 was called Attack of the 50 Foot President in a reference to the 50s B Movie. Funnily enough, you fight a 50 foot robo-president Brain in a Jar.
- Destroy All Humans! 2 has a boss fight in Takoshima with Kojira.
Referenced in Discworld II, where you see a movie poster advertising Attack of the 50-Foot Dwarf. Also, in the endgame, a 50-Foot Elf Queen comes out of the cinema screen and you have to defeat her.
Dino Rex: All of the playable dinosaurs in this game are already pretty oversized, and the bonus stages that you play after beating each two story mode levels allow your dino to wreck a modern city, stomping military vehicles, reducing buildings to rubble and eating soldiers and unlucky bystanders in true Kaiju style.
Disgaea:
- In Disgaea 2: Cursed Memories, Flonne's angelic attacks from the first game are obviously unusable. Instead she gets to grow to giant size, wear a big patchy dinosaur costume, and breathe fire while prop planes with obvious strings fly overhead. One of the worst, yet probably the greatest, attack in the game.
- Monster units in Disgaea 4: A Promise Unforgotten have the ability to fuse with another monster to approximately triple them in size.
- The upcoming Disgaea 7 features the Dokeda MAX system, allowing units to grow to titanic sizes to loom over the entire map. Aside from cracking open similarly sized Treasure Chests, these units can also hit the entire map with their attack.
DOOM Eternal has this in the game's final boss, the Icon of Sin, which is seen as the Khan Makyr's Godzilla Threshold against the Doom Slayer. It has to be defeated by destroying all of its armor and then shooting it to Ludicrous Gibs and even then, it cannot die because it's completely immortal. The only way Doomguy gets rid of it is to jam the Crucible into its brain and break the blade off to seal it away.
Dragon Quest V: Bjorn the Behemoose is an ancient goat-like mountain-sized demon. He is easily one of the largest bosses in the franchise.
In Drakengard, the canon Final Boss is fighting a giant Manah. Play the game more, and you'll run into a no-less-gigantic Grotesquerie Queen.
Dungeon Fighter Online has a Shout-Out to the above in the form of Quattro Manus, currently the last boss on the last Special Dungeon (King's Library on the Castle of the Dead), you fight him on top of a tower a la Onslaught, complete with attacks from the background, a grab that it's lethal if you don't button mash enough, and a obscene number of life bars. If you aren't prepared for this fight, you (or your party) WILL lose many Life Tokens.
Dwarf Fortress has giant versions of many animals, the largest being the giant sperm whale which is larger than a real world blue whale. Gods help you should a giant sperm whale ever be infected with undeath as they will then proceed to come onto land to murder your entire fort. Other giant animals include giant sponges, which while not as deadly as in an earlier version where they were effectively invincible (except to copious amounts of magma, a drawbridge, having the water they were in drained, or a cave in) can still fuck your shit up far more then any sessile animal ought to be able to, and giant cave spiders which have a poison that will slowly but inevitably kill your dwarves (and most other creatures) via total paralysis followed by suffocation.
- Forgotten Beasts are usually depicted as this trope in fanart. Considering how much resources can be harvested from one, it is safe to say they are quite large.
EarthBound (1994) has one area, the Lost Underworld, where everything is so huge that the characters' sprites shrink. This includes the enemies.
- Fortunately, they later encounter the Dungeon Man (a man the size of a dungeon!) who sees them through.
Earth Defense Force 5: The player finds themselves fighting giant bipedal alien frogs and Grey aliens in armored suits both armed with energy weapons and accompanied by the hordes of giant bugs.

- When Mehrunes Dagon, the Daedric Prince of Destruction, manifests in Mundus (the mortal realm), he typically does so in this fashion. When he briefly took form during the 11th hour of the Oblivion Crisis, he towered over everything else in the Imperial City.
Pandemonium in Everlong.
EXTRAPOWER: A staple in the series, given some of its tokusatsu influences. Certain enemies like Stone Mack or Sinner Shiner are already gigantic, recurring bosses Mensouma and Undata are sometimes imbued with dark energy to double their size. In EXTRAPOWER: Star Resistance, Undata becomes large enough to be as tall as half the stage, and one of the final bosses is against the gigantic, muscle-bound Shakun Star Central Computer.
Fallout 3 has Super Mutant Behemoths, and on the player's side, Liberty Prime.
David Crane's Ghostbusters from Activision has the Stay-Puft Marshmallow Man make an appearance to stomp down buildings on the city map if the player doesn't lure it away using ghost bait, as well as block the entrance to the building that the Ghostbusters must enter to stop Gozer in the final battle.
Gigantic is a MOBA centered around two teams fighting alongside giant creatures known as Guardians, with the goal of defeating the enemy team's Guardian.
There is a pill that allows this in Streets of Rogue, and doing so allows you to break wall blocks and squish people.
The God of War series absolutely loves this trope. The first game features, among its bosses, a Hydra so large it more or less takes up the entire level, a gigantic robot/cyborg/Steampunk minotaur, and Ares, who could probably wrestle Godzilla. The sequel has Kratos get in on the act briefly, pulling a Godzilla-Of-War on Rhodes, and then fighting the Colossus of Rhodes while normal-sized. While Zeus is close to Kratos' size the time you fight him, he's still noticeably larger than the already-abnormally-large Kratos. Titans, giant monsters, and oversize gods abound in the rest of the series.

King of the Monsters, is a Fighting Game where the competitors are giant monsters.
Kirby 64: The Crystal Shards downplays this. Rock + Rock turns Kirby into an oversized Mighty Glacier version of himself. Take Fridge Logic and the fact that Kirby's 8" tall, and you realize that the Rock + Rock Kirby is 1'04"! (50ft would actually be 37.5 times as large as Rock + Rock Kirby)
- Star Dream in Kirby: Planet Robobot. While it was already quite huge to begin with, when it merges with the Access Ark in the second phase it becomes the size of a small planet, being one of the largest final bosses in the series to date.
- King Dedede goes through this in Kirby's Blowout Blast. After his defeat, he absorbs the power of a Sparkling Star and grows to the size of a giant. The final time he does this, he combines it with the Cool Mask of Masked Dedede to make Giant Masked Dedede.
- Void Termina in Kirby Star Allies, fitting for his role as the "True Destroyer of Worlds". His outer shell, at least. His core is at least thrice as big as Kirby.
In The Legend of Zelda game Hyrule Warriors:
- With the Summoning Gate, Lana can bring up a gigantic Cucco to devastate the battlefield.
- Ganon's Fury mode lets you play as a Giant Boss. Link's Great Fairy "weapon" (read: she does the fighting while Link is stuck in a bottle) works similarly in other modes. And you can unlock the Cucco as a playable character in Ganon's Fury.
Lemegeton's first episode ends with a fight against Gaap, a huge demon who may literally be fifty feet tall. The best way to describe him is a kind of humanoid fort that periodically sweeps one side of the room with a petrifying beam.
An early level in 3D Lemmings is "Attack of the 50 foot Lemming" — your lemmings start on the giant lemming's head and make their way down to the feet. Unfortunately there's no attacking, just a level designed to look like a giant lemming.

Late in the Japan-only PC-FX game Makeruna! Makendou Z, after our heroes are put to sleep by Honmayaner, Hikari dreams that she is a giantess fighting a three-headed dragon.
The Matrix: Path of Neo. At the end of the game, which corresponds with the end of Matrix Revolutions, two avatars of the Wachowski siblings themselves speak directly to the player and explain that, while the Martyr ending was OK for the movies and the story, it just wouldn't work that well for a videogame. So instead, all the Smiths get together and grab various bits of destroyed junk and debris, as well as a giant pair or sunglasses from an ad, and for a GIANT Smith.
Mario & Luigi: Bowser's Inside Story: Parts of the game have Bowser grow to enormous proportions and fight giant enemies, usually after he's been nearly crushed to death by them, and needs the Mario Brothers to revive him from within.

Muramasa: The Demon Blade:
- Momohime's fourth boss, Ippondatara. You have to fight his giant foot first (which refers to a legend regarding one of Kyoto's mansions), then his huge body. From time to time he will turn into the harmless Inosasao (a giant boar with bamboo leaves on his back).
- And then there's the giant centipede, the second boss in Kisuke's story.

A series tradition in Resident Evil is fighting creatures that became giant sized usually as a direct result of the T-Virus. So far, in order, the heroes have had to fight a snake as big as a bus, a great white straight out of Jaws, a spider big enough to crush a tank, an alligator that can barely fit in the hallway you fight it in, a caterpillar that that can swallow a man whole, an earthworm that can swallow a man whole, another spider that can crush a tank, and a salamander so large it can drag a boat around.

Shin Megami Tensei IV gives the ultimate DLC challenge against Tokyo local protector deity Masakado. While in other games is a normal sized human, in this case is a being so giant that skyscrapers protrude from his shoulders, his hands are giant roots ripped from the earth, his waist is connected to the ground via magma, and is so big that he could be measured in kilometers. He can completely cover the whole city of Tokyo (creating the Firmament) and also host a complete medieval society on his very back (several villages, a big lake and fortified city with several protective rings, huge castle included). His inner body includes Naraku, a giant maze cave which is home to several demons connected to the freaking Sky Tower that links both Tokyo and Mikado. And he's also strong enough to tank a last-gen nuke. You actually can't beat him in the game, you have to calm him down in ten minutes (ten turns in game) so he can tank the Nuke before it turns Tokyo into Blasted Tokyo. A pic for reference.
Shin Megami Tensei V has Surt, a giant humanoid demon whose flaming BFS alone is as tall as the buildings in his immediate vicinity, and Lucifer, who's as tall as the Tokyo Tower ^note in this game. His true form isn't as gigantic, but he's still several times taller than the Nahobino.

Super Mario Bros.:
- In Yoshi's Island, the bosses are normal enemies made giant by the magic of Kamek (except for one battle that involved Yoshi and Baby Mario getting shrunk). In fact the final battle involved Kamek enlarging Baby Bowser to a size bigger than the castle they were in.
- There's also New Super Mario Bros., Super Paper Mario, and Super Mario 3D World, where there are power ups that can make the player character grow as tall as the screen and tear through enemies and obstacles.
- There's also Giant Land in Super Mario Bros. 3, where all the standard enemies are now bigger than Mario or Luigi.
- A recurrent boss in the 3-D games is a Goomba as big as a house.
- Bowser at the end of New Super Mario Bros. Wii looks rather similar to Godzilla.
- Mario & Luigi: Bowser's Inside Story has Bowser being super-charged on adrenaline and growing super giant in order to battle his hijacked castle, a giant robot coming out of nowhere, a train, and Princess Peach's Castle (as remodeled by Fawful), preceded by Bowser being crushed by the buildings.
- Mario & Luigi: Dream Team has Luigi grow to giant size in the Dream World to face off against giant bosses. In a nod to the previous game, he ultimately gets to face off against a giant Bowser in what's probably his most triumphant moment in the series.
- Paper Mario: The Origami King has the Paper Macho Soldiers, large versions of existing enemies made of papier-mâché. Most are only three to five times Mario's height, but the Paper Macho Shy Guys in Overlook Mountain are about ten times Mario's height, and the Mega Paper Macho Pokey in Scorching Sandpaper Desert is at least the size of a building. The latter is a deconstruction, as its size causes it to fall over every several seconds, which gives Mario the opening he needs to fight it—as it gets shorter as Mario destroys whatever segment is at the bottom at the time, the Mega Paper Macho Pokey falls over less and less. Then, King Olly folds himself into a giant origami beast for Mega Bowser to take on. He then gets even larger as Mega King Olly during his Villainous Breakdown.
Mario Party 10: Bowser towers over Team Mario in Bowser Party mode, being even larger than the nearby buildings like the mid-boss fortresses. He destroys much of the scenery as he charges through the boards in pursuit of Team Mario.

Super Smash Bros.:
- In Super Smash Bros. Brawl, Jigglypuff's Final Smash, Puff Up, causes her to grow/inflate to such a size that it can push other characters off the stage. Most evident on small stages.
- Bowser's equivalent Final Smash move involves turning into the dreaded Giga Bowser and wreaking havoc on everybody. Giga Bowser is much larger in Melee than he is in Brawl, and can get Super-Mushroomed to a downright ridiculous size.
Team Fortress 2 lampshades this in their promotional material for an update to Mann vs. Machine, when the robotic Engineer was added.

Touhou Project:
- Suika utilizes her control of density to grow herself really large and heavy for some of her attacks in Immaterial and Missing Power and Scarlet Weather Rhapsody.
- The plot of Hisoutensoku boils down to three characters seeing an impossibly huge shadow of something and going off in pursuit of whatever it was (though only one of them successfully tracks down the cause of their respective shadow). The last boss fights of Cirno's and Meiling's scenarios do this to a doll and a catfish, respectively. In the latter case, the catfish starts off as merely huge and continues to grow each time it attacks. Sanae's scenario inverts this by making her last boss the shortest character in the game.
- New Super Marisa Land does this for the final boss.
One of the bosses in Transistor is "The Spine of the World", a massive Process that resembles a horseshoe crab with a long, spiked prehensile tail that it uses to attack Red as she climbs Highrise to get to it.

A guy proceeds to give the player magic beans that, when consumed, cause the player to grow to an enormous size, giving the player an advantage over Jack, who is promptly swatted away by the player.

Giga Bowser in The Ultimate Crossover and Remastered, Zarok’s cobra form in 2), as well as villains who are already rather jumbo-sized in the first place (E.g.

SheZow foe Manny Ken is a gigantic animated shop mannequin.

In one episode Squidward becomes a giant after getting sprayed with plant fertilizer, and in another episode SpongeBob inadvertently becomes a giant after shrinking everybody in Bikini Bottom. Unfortunately, a giant (to them) Plankton is returning from his vacation only to find the inhabitants small enough.
Steven Universe:
- Most of the fusions fall in this category. They're all taller than their component Gems, but some are only tall by human standards (like Garnet, Stevonnie, Rainbow Quartz, and Smoky Quartz), while some are just massive. Opal can carry Steven under her arm, Sugilite is the size of a building, Sardonyx is as tall as Sugilite but narrower, and Alexandrite and Malachite are straight Kaiju-size. "Know Your Fusion" shows that Sardonyx has to squeeze herself to get into the temple door, and she can block it with her hand.
  - The largest fusion yet seen, Obsidian, is about the size of one of the Diamond Mecha's hands, thus making her bigger than any of the Diamonds, and quite possibly more powerful. She does have one of the Diamonds themselves as a component, after all.
- This is taken Up to Eleven with the Cluster, an enormous fusion comprised of billions and billions of gem shards, with a diameter comparable to the size of the Empire State Building. Except, that diameter is not the diameter of The Cluster itself, but of its gem! Peridot reveals its actual size in "When It Rains".
  Steven: Peridot, you're saying there's a giant mutant gem the size of the Earth under us right now?!
  Peridot: Oh no, when it forms it'll be much, much bigger than the Earth!
- For non-Fusion examples, the Diamonds. Blue and Yellow Diamond are between 30 to 50 feet tall; at one point Yellow is shown holding two Pearls (who are about human-size) comfortably in her hand. White Diamond, who wasn't seen until near the end of season five, turned out to be even taller than that. Pink Diamond averts this — she's only about twice as tall as Pearl.
Apache Chief from Superfriends. And Giganta, his arch-enemy. And, if you count Justice League, Long Shadow from the Ultimen.
- Also from Justice League Unlimited, Supergirl once fought a giant fire-breathing turtle creature in Japan. (Its shock of red hair and the way it shrunk when defeated means it might have been a Shout-Out to Jimmy Olsen's Silver Age stint as "Giant Turtle Boy" as well as Bowser and/or Gamera.)
- Also from Superfriends is the episode "The Giants of Doom". Guess what happens to Bizarro, Sinestro, Captain Cold, and Toyman in that one.
In the Sushi Pack episode "A Very Big Deal", Ikura is shot by a malfunctioning shrink ray and grows to enormous size, fulfilling his earlier wish to be bigger.
In the first Teenage Mutant Ninja Turtles series, Krang became giant using a "molecular amplification unit". The Turtles entered his body to disable the device, and return him to normal.

The Tick vs. Dinosaur Neil, in which a paleontologist in a dinosaur costume turns into the real thing after mistaking prehistoric genetic material for pasta salad. One scientist who bears more than a slight resemblance to Dr. Strangelove wanted Niel to put on some pants. So he made a giant pair of pants and planned to have the army lure Neil to the pants so he could put them on. The pants caught on fire before anything could be done with them.
- A later episode had the series' Big Bad Chairface Chippendale using a pill to turn Neil back into a dinosaur on his wedding night.

Happened once in Trollz. Dragon vs. Fifty-Foot Kitty.
