Make My Monster Grow

The situation is quickly becoming grizzly.

Tommy Oliver: Let me guess - there's a 30-story version of the guy you were just fighting?
Ethan: You've done this before, haven't you?
Tommy: Once or twice.

— Power Rangers: Dino Thunder

The villain (or the villain's servant) grows to an enormous size for the very definitely Final Battle. No, he doesn't go and get mutated into a terrifying One-Winged Angel form (usually), but simply becomes an absolutely huge version of himself, pretty much the attack of the 50-foot villain. Usually done as a last resort when the villain has nothing left to lose, quite literally making this the Godzilla Threshold.

In some cases, this goes with a villain comeback after an assumed death by dangerous substance or fall, or getting hit with a bunch of energy beams and "exploding". There is also a pretty good chance the villain's castle or base will be nearly, if not completely destroyed when the villain does this and in certain funny usages of this, the villain or Monster of the Week will realize the unfortunate consequences of both the enormous size and the misfortune of standing on a piece of flooring that's by far too weak to support him. And finally, no matter how powerful or gigantic this villain becomes, never rule out the Bishōnen Line, in which this monster will suddenly revert to a more humanoid appearance as a result of gaining even more power.

Compare Attack of the 50-Foot Whatever, Miracle-Gro Monster, One-Winged Angel, Rent-a-Zilla, Sizeshifter and Turns Red.

Please try to only list examples where the villain's increase in size is the only change to his appearance, since most One-Winged Angel forms by definition are usually larger than the original character.

Not a Double Entendre. Usually.

• Live-Action TV

Anime & Manga

• 3×3 Eyes: after the return and revival of Kaiyanwang, his Wu Benares gets a power boost and in each appearence becomes bigger and bigger: by the end of the story he's turned into a giant, so large that he can grab Yakumo like a doll and literally crush him underfoot.
• In Buso Renkin, Victor does this, although it's to combat a giant robot, the Buster Baron. It's explained that he used the bodies of all the dead creatures around him to create a giant version of himself around him. When the Baron destroys the giant form, he leaps out and catches them by surprise. Doesn't explain where he got the giant pants from, though.
• Digimon:
  • In the 13th episode of Digimon Adventure, Devimon grows to giant size, eating Ogremon to help himself do this. After beating up the first six Champions this way, he's killed when Angemon uses up all his energy to destroy him.
  • Digimon Tamers: It's only shown once, but Ryo has a card that enables his partner to grow to a monstrous size, and it's stated that it's too much for anyone who's not a master Tamer to handle (in the original, it's called "King Device", and the "[chess piece here] Device" cards in general are too dangerous for amateurs; in the dub, it's given the simple and Meaningful Name of "Goliath").
  • The first arc of Digimon Data Squad had all their Mons Of The Week several times larger than what they would usually be, and sometimes they were even shown normal sized before growing. This indicated, of course, that there was a reason for this. Ironically, with all the parallels Savers had with SPD/Dekaranger, this was not one of them.
  • The Grand Finale of Digimon Fusion has Bagramon grow to gigantic size for the final battle. He also pulled out a One-Winged Angel form for this fight, but the growth was a separate thing.
• In Dragon Ball, Piccolo Junior did this during his big fight with Goku near the end of the original series. It was Goku who goaded him into doing it, so he can jump down his throat and retrieve the jar holding Kami.
  • Lord Slug did the same trick in Dragon Ball Z: Lord Slug. Apparently this is a common power for 'Super Nameks'.
    • The Saiyans also do this as well, using either the full moon or a technique creating an energy ball mimicking a full moon to transform into a giant monkey called an Oozaru.
• In Jewelpet (2009), Diana and Dian can both do this.
• Mazinger Z: In episode 12, Baron Ashura used a size-changing ray to turn a tiny robot into a giant Robeast -Bicong O9-. That ray had been invented by Big Bad Dr. Hell, who previously tested it with Ashura himself/herself, briefly transforming it into a giant. Throughout the series, Hell used more Mechanical Beasts could grow their size.
  • And in Great Mazinger one of the Co-Dragons -Marquis Janus- could change sizes, too.
• In The Red Ranger Becomes an Adventurer in Another World, Lurguat's Seed of Magic goes berserk after his defeat, overwhelming his body and turning him into a giant mass of flesh large enough to flatten all of Akarina should it fall. Luckily, Red has the Maximum Kizuna Kaiser to push it into outer space where it can be safely destroyed. Also lampshaded, as Red says that this is already a part of his routine as a Toku hero.
• Transformers: Cybertron. Starscream. Stolen Omega Lock power. Bursts out of a volcano. While triggering an eruption. Then forges a crown for himself out of the molten magma.
  Starscream: All of you will bow down before me or face my wrath!
• In Transformers: Energon, Galvatron grows to Unicron size after overdosing on Super Energon. Optimus Prime can do something similar when powerlinked with Omega Supreme.
• In Voltron, it was common for Zarkon's commander to use either magic or science to make the Robeast-of-the-Week grow much larger as it prepares to fight against Voltron. In one especially literal example, after Prince Lotor replaces Commander Yurak as leader of Zarkon's attacks on Planet Arras, Yurak is enlarged into a giant robeast and pitted against Voltron himself.

Comic Books

• In Aquaman: Andromeda, Black Manta finds himself battling a giant copy of Aquaman as the Darkworld takes hold of his fears.
• Watchmen: After the Big Bad vaporizes Dr. Manhattan with an intrinsic field remover, Doc comes back huge. Then he shrinks down to normal size again after smashing the building open with one hand. Dr. Manhattan won the Vietnam War this way as well.
• The Spectre, who's been cast as both a protagonist and an antagonist, does this a lot.
• In the Marvel Godzilla comics, as the heroic monster battles the intergalactic Mega Monsters (Rhiahn, Triax and Krollar), their alien commanders zap them with an "Energex Ray," doubling the monsters' sizes and making them tower over Godzilla.
• In one Fantastic Four issue, Reed Richards (prior to the space journey) observes that an alien monster's footprints are getting larger, but not deeper, at it grows in response to attacks. He then tells the officer in charge of getting rid of the creature to keep firing. The bombardment forces the creature to grow and grow and grow... and to become less and less dense, until it becomes a full-on kaiju... and slightly less dense than fog. It dissipates.
• The climax of Venom: The Enemy Within limited series has Demogoblin use the power or an old enchanted necklace to grow to 20 feet, seemingly for the final battle with Venom and Morbius. However, he actually uses it to drown the hordes of evil otherworldly goblins in the river.
• He-Man/ThunderCats presents a heroic example. Orko accidentally turns Snarf into a giant, knocking out one of the Ancient Spirits of Evil in the process.
• It happens in the Superman storyline Two for the Death of One when Syrene is fighting Satanis in a limbo dimension. During the battle, Syrene uses her powerful magic to make herself grow until she can hold a planet with both hands.

Fan Works

• The Bridge has Garble and his gang of teenage dragons experience rapid greed-growth fueled size expansion out of craving revenge on Rainbow Dash for humiliating them and desire to eat a campground of fillies and colts. Thankfully a chance activation of magic from Rainbow Dash's Element of Harmony causes the then transformed-into-a-pony Anguirus to return to his true form and give the story it's first proper Behemoth Battle.
• The Last Son: During the climax of Book Two, Superman, Green Lantern, and Hawkgirl engage in battle against the Brainiac Emulator Unit Mark VI. When it seems they've destroyed it, it re-emerges by having fused with the destroyed Sentinels, becoming a 200-foot tall metal monstrosity.
• Son of the Sannin: During the Kakuzu and Hidan arc, the latter reveals his ability to summon demonic creatures called the Sons of Jashin. After a fair amount of them get destroyed during the battle for Takigakure, the remaining ones retreat seemingly to regroup, only for them to merge into a giant monster known as the Wrath of Jashin, an avatar of the evil god according to Hidan's mooks.
• Here There Be Monsters: Captain Marvel's villain Red Crusher was a normal-sized superhuman until Doctor Sivana doused him with a growth serum which turned him into a fifty-foot giant.
  One of their foemen was human, or appeared to be, if one could discount his fifty-foot height. He was dressed in the uniform of a North Korean Communist army officer, and he wielded a spiked mace on a chain many times the size of a wrecking ball. This was the Red Crusher, an old foe of Captain Marvel's. As a regular-sized villain, he had been trouble enough. But Sivana had found the formula that the Communists had used to expand one of their soldiers, Mong, to titanic size some months ago, dosed the Crusher with it, and endowed him with a ball-weapon in proportion to his new height.
• Power Rangers Take Flight adapts Choujin Sentai Jetman, and thus their method of making monsters turn giant (having the bug creature, called a "Jinnsect", create the monster, and latch off to enlarge it); at one point in the fic, with the Zords inoperable, they begin to shoot the Jinnsects to pieces to prevent a monster growth. However, the red bugs used later in Jetman were Adapted Out in favor of using biomass to create monsters; it's stated a few times something called a "fractal matrix" is responsible for the growths, and for some monsters that didn't grow, the matrix "misfired". In at least one case, they triggered a monster's growth to test said matrix.
• In Sonic and the Death Cheese 2, the Death Cheese 2 eventually grows colossal-size for no apparent reason, which Tails lampshades.

Films — Animated

• In Barbie and the Secret Door, Malucia grows gigantic to deal with Alexa and nearly crushes her with her scepter.
• A classic example was shown in The Little Mermaid (1989); during the climax, Big Bad Ursula gains the godlike powers of King Triton and uses it grow into a towering monster to murder Ariel. She also does this whenever she shows up in the Kingdom Hearts franchise.

Films — Live-Action

• Happens to Sark in TRON and Kingdom Hearts II.
• Idiocracy lampooned this. During the demolition derby match, the third enemy was so big ... his truck wouldn't fit in the tunnel to enter the arena.
• Dude, Where's My Car?, of all things. The alien "hot chicks" who have been after the protagonists to steal the Continuum Transfunctioner in their possession merge into one, becoming a "Super Hot Giant Alien".
• The Stay-Puft Marshmallow Man from Ghostbusters (1984) was one of these. He started out as a cute little cartoon mascot not unlike the Pillsbury Doughboy, but Ray Stantz's choice of him as the form of the Destructor made him gigantic. In fact, his size and mass are the only dangerous things about him.
• Godzilla:
  • While not a villain, Jet Jaguar does this to himself in Godzilla vs. Megalon when he realized he had to distract Megalon until Godzilla arrived. The only problem was that Gigan showed up first, and he and Megalon beat the stuffing out of Jet Jaguar...
  • Also, Minya in both All Monsters Attack and Godzilla: Final Wars. In the former movie it was part of a child's fantasy, but in the latter it was presented as a natural part of Minya's evolution.
• Features in the Taiwanese monster film, King Of Snake. A top-secret bio-lab in Taiwan discovered methods to create diffractor rays from an aquarium-like device, using it to turn a regular frog giant-sized within seconds of exposure. But a criminal syndicate who wants the device for their own purpose attacks the place, the device got lost in the countryside in the struggle where a young girl named Ting-Ting is hiding a snake she found in a pond from her parents found the device, and mistook it as a terrarium. Her pet snake eventually became a titanic serpentine monster who goes on a rampage and took out half of Taipei with it before it's killed.
• Averted in Mighty Morphin Power Rangers: The Movie! The two Ectomorphicon Titans are already giant, and the only "growing" is when Ivan Ooze merges with one of them. Played straight in Turbo: A Power Rangers Movie, where Maligore makes himself grow in a massive burst of flame.
• The 360-degree short film "HELP" made by Justin Lin and YouTube, is a one big presentation of this trope. A cute alien crash-lands on Earth, and before it can phone its companions for help, a random by-passer steals its "cell phone". The alien gives chase, getting madder and bigger as she evades it. It's not an aggressive being, but becomes so in response to aggression, evolving into a menacing character armored in spikes and muscles. It's soon a whopping 200ft tall, before the lady finally realizes her error and surrenders its phone back. The alien shrinks back down and happily departs with no further issue.
• In A Simple Wish, Mara Wilson's character wishes for her "fairy godmother" turn an antagonistic man into a rabbit. He (yes, ''he'') ends up turning the man into a giant rabbi. That's just the least of his screw-ups.
• In Teenage Mutant Ninja Turtles II: The Secret of the Ooze Shredder drinks his last vial of ooze, causing him to mutate into a bigger, more muscular version of himself known as "Super Shredder". Unfortunately, in his revenge-fueled rage, Super Shredder recklessly demolishes the supports of the pier in an attempt to crush the turtles, not carrying about the possibility that he'll be killed as well. As a result of this, along with the turtles quickly leaping into water, he is the only one crushed underneath the wooden rubble while the turtles escape unharmed.

Literature

• An unusual literary example is David Eddings's The Belgariad. When the final battle between Belgarion and Torak is about to start, both combatants suddenly decide to become huge. Explained post fight by Belgarath; since Torak was so much larger than Belgarion, they both grew to even the fight, as dictated by the powers that be. Though as Torak only had a few feet on Garion to begin with, blowing them both up to 50 feet seems a bit egregious until you take into account the Hounds of Torak crawling around the ruins. A 10' tall Garion going mano e mano with your God? Go for the throat. A 50' tall Garion that could squish you underfoot? Yeah, run like hell.
• A heroic example: Tanu, the potion master from the Fablehaven series does this occasionally. In the finale of Book 2, the artifact is protected by what appears to be a harmless cat. When you kill it, it is resurrected as a larger cat. This happens eight times, until the cat is a winged, three-headed, three-tailed monstrosity with snakes sprouting out of its back.
• The demons in Tales of Kolmar have size-changing powers. When they fight their mortal enemies the Kantri, they grow to match sizes. Some flames are exchanged, but the battles are won or lost through physically grappling, biting, clawing etc.
• In Spirit Animals, the Slate Elephant supersizes the spirit animal of whoever's holding it.
• In The Nekropolis Archives, Lyncanthropus Rex is a werewolf with the unique additional ability to increase his size, growing up to fifty feet tall.

Tabletop Games

• Munchkin has a "Humongous" card which can be played on any monster in combat. When played on the Fungus, it has a greater than usual effect.
• Magic: The Gathering:
  • Pictured above is the classic "Giant Growth" card, which increases a creature's strength and toughness by 3 each (for reference, an average dragon in the setting would be either a 4/4 or a 5/5). There are also variations on the card, such as Mutagenic Growth (which can be paid with life instead of mana, but it's effect is reduced to +2/+2) and Enlarge (gives +7/+7 and forces enemy creatures to block it)
  • The use of +1/+1 counters on creatures is seen as growth in size as well; this is used in various mechanics such as Devour, Monstrosity and Evolve (to name a few). There are also variants on the aforementioned "growth" cards that gives +1/+1 counters, although usually in less quantities because of the fact that +1/+1 counters are permanent rather than a temporary boost.
  • Some Auras giving power and toughness boosts are represented as this as well. The most well known is Eldrazi Conscription. There's also Gigantiform, which can cause a chain reaction of things getting huge.
  • Gigantomancer, which costs a good deal to cast but can very easily turn a lot of creatures... gigantic.
• The RPG Mecha vs. Kaiju is, as the name implies, about mecha pilots fighting monsters. Most are already giant, but it acknowledges the Sentai convention in one sidebar and gives rules for duplicating it in the game.
• Inverted in the board game The Awful Green Things From Outer Space; the crew of the spaceship Znutar need to test various weapons and hopefully find one that causes the eponymous invaders to shrink, reverting to a less-dangerous stage in their life-cycle. However, an unlucky choice of weapon may play the trope straight by causing the Awful Green Things to grow and/or reproduce.
• Dungeons & Dragons:
  • The game tends to include a few spells for this purpose among its various lists, depending on edition. Some will only work on specific creature types like animals or insects, others (like the low-level wizard spell Enlarge) can be cast straight on one's own fellow player characters.
  • Blood apes are a type of red-tinted gorilla with the ability to enlarge themselves, but they only do this in combat, retaining a smaller size to keep their feeding and nesting requirements down (already being six feet tall).
  • Holyphants are tiny, fluffy, winged elephants from the Upper Planes that have the ability to grow to the size of mammoths in order to combat evil.
  • Spriggans are evil fey that normally look like old, wrinkled gnomes but can grow to the size (and strength) of giants in combat.

Video Games

• In Spore, during the Space phase, you can eventually obtain an enlarging beam to make a creature colossal in size.
• Bowser from Super Mario Bros. has done this a few times, to wit:
  • Super Mario World 2: Yoshi's Island: Every single boss except two is a normal enemy enlarged by Kamek's magic (The two being Prince Froggy, who remains normal sized while Kamek shrinks Yoshi, and Roger the Potted Ghost, a ghost not belonging to any normal enemy species). Of special note is giant Baby Bowser, who's big enough that if he gets too close, he destroys the entire castle and Yoshi plummets to his death.
  • Yoshi's Island DS: Every boss is enlarged by Kamek prior to battle, with the exception of Hector the Reflector, Priscilla the Peckish, Six-Faced Sal (all of whom don't belong to any enemy species), Moltz the Very Goonie, Big Guy the Stilted (who are both natural King Mooks in that they were already giant when Kamek brings them in) and Baby Bowser.
  • Bowser has also been magically supersized for the final battles in Super Princess Peach, Mario Party 5, 9 and 10, Paper Mario, New Super Mario Bros. Wii, New Super Mario Bros. 2,^note which also extends the privilege to Dry Bowser for the first time and New Super Mario Bros. U.
  • The first time you see him in Super Mario Galaxy 2, he's already "HUUUUGE!" And then he gets EVEN BIGGER for the final battle.
  • Also in New Super Mario Bros. Wii, Iggy Koopa's magic enchanted Chain Chomp.
  • Mario Party DS: The trend is inverted; every boss except Bowser is larger than usual, due to the cast being shrunk. Prior to the Final Boss battle, all the main characters (including the one you're playing as) return to their original size, thus settling the final duel on equal grounds.
  • Paper Mario: The Thousand-Year Door has the Huge status which doubles the size of a character and boosts their attack by two for two turns.
  • Also inverted in Super Paper Mario, where O'Chunks does a "CHUNK UP!" for his one-on-one battle with Bowser in World 8-1.
  • In Mario & Luigi: Bowser's Inside Story, Bowser goes giant-mode several times throughout the game when fighting similar sized opponents. And he's playable. Mario & Luigi: Dream Team follows it up by answering the age-old question of what happens when Bowser becomes giant and then gets help from Kamek.
• DK: Jungle Climber has giant King K. Rool as the final boss.
• Spider-Man:
  • In the 2000 video game, Mysterio uses his illusionary powers to make himself appear to grow.
  • The first stage of the arcade game has Venom use a magical stone and a large puddle of symbiote to turn big, and what follows is chasing him down over three battles in a zoomed-out platforming scene.
• The Guy from I Wanna Be the Guy grows to enormous size for the final battle.
• A monster unit in Disgaea 4: A Promise Unforgotten can fuse with another monster to increase its size by about three times, which grants them a multitude of benefits.
  • In a boss example, Des-X does this through her own will for the second phase of her battle.
  • Disgaea 5, has a few examples of its own:
  • Usalia's "Prinnical Meteor" has her unfurl a ninja scroll before enlarging her Prinny mount to... about the size of the moon. Before flinging it back to earth and eating a plate of curry as she casually floats away to the view of the Prinny's impact.
  • Red Magnus has this as his skillset (he can naturally change his body structure's dimensions, such as smashing foes with an enlarged arm), but his Overload skill is where this trope comes out to play— it increases his size and gives him a stat buff for several turns. Hilariously, he has a team-up skill with the aforementioned Usalia which involves enlarging both the Prinny Mount and himself to crazy proportions before smashing the planet with Usalia's hammer.
  • There's also the Giant Killer Squad, which makes its assigned members giant for a few turns.
  • However, the best example of this trope is one of the Professor's unique skills, which can enlarge several targets on command.
• Being an Affectionate Parody of Super Sentai and Power Rangers, Chroma Squad features monsters growing to colossal proportions, necessitating your team's Humongous Mecha to put it down.
• DK in Donkey Kong '94 (the Game Boy one).
• Castlevania:
  • While most of Dracula's second forms are One-Winged Angels, he resorts to this in Haunted Castle.
  • Paranoia in Castlevania: Dawn of Sorrow, though less by magic and more by virtue of finding an adjacent room with a larger mirror.
• For Capcom vs. examples, Apocalypse in X-Men vs. Street Fighter.
• In Drakengard, one of the paths has the final boss be a gigantic Manah that shoots magic projectiles at you.
• Super Smash Bros.:
  • Mario's original taunt has him grow to giant size for one second and then shrink back down. It's just for show, though.
  • Snorlax's Body Slam attack works like this: whenever it's released from a Poké Ball, it leaps off the screen and then comes back down a few times bigger, hurting whoever it touches (other than the one who released it).
  • Super Smash Bros. 64: In the 1P Game campaign, one of the enemies is Giant Donkey Kong.
  • From Melee onward, Giant Mode is an option in multiplayer, making everyone jumbo-sized for the match.
  • The Super Mushroom item introduced in Melee gives any player who picks it up a boost in size and ability for about ten seconds. The Lightning Bolt introduced in Brawl generally shrinks all of the opponents but can sometimes super-size them instead.
  • In Brawl's Subspace Emissary mode, the Shadow Bugs at one point create a giant dark copy of Diddy Kong. This is one of the toughest fights in the game despite not being an actual boss.
  • Also in the Subspace Emissary, Nagagogs are sumo-wrestlers that, given the chance, will grow bigger and stronger depending on their health bars. Close to full, they're small and blue. Half-gone, they're bigger and yellow. Close to empty, they turn giant and red. And their offensive and defensive capabilities grow accordingly.
  • One of Tabuu's attacks in Brawl is to enlarge himself and fire Eye Beams.
  • Jigglypuff's Final Smash, Puff Up, causes it to grow big enough to fill any of the smaller stages, pushing everyone nearby into the abyss and sending them flying if they're near enough when Jigglypuff's size peaks and it cries out before returning to normal. Bowser's Final Smash, Giga Bowser, overlaps with One-Winged Angel.
• Ratchet & Clank is made of this trope. The boss at the end of the original pilots a giant mecha. Ditto for Deadlocked and Tools of Destruction. Going Commando has the final boss be a suddenly supersized enemy. This trope is also the main idea behind the non-canon Size Matters.
• In Banjo-Tooie, Klungo grows to giant size after consuming his red potion. "Now Klungo sssquasssh!"
• In the fighter Touhou Suimusou ~ Immaterial and Missing Power, final boss Ibuki Suika does this as a function of one of her declared attacks "Second Card [Giant Oni on the Scroll]." Her power is control of density^note Presumably by increasing volume and increasing density so it only makes sense that she can do this.
  • On a Touhou imageboard, there was once a discussion over the implications of her abilities, one of them being the possibility that Suika, while in her mist form, could be inhaled; another being that, if she doesn't have a limit to how big she can become, she would be one of the series' fastest characters (despite herself already having impressive agility, according to tengu reporter Aya Shameimaru, who claims to be the fastest character in Gensokyo, the game's setting), with her smallest moves surpassing by far the speed of light; the last of them being, as a joke reply to who would be the most powerful character in the series, one poster mentioned her scale-increasing ability, to which someone else replied saying that "n times zero is still zero"
  • Alice Margatroid pulls off a more literal example of this trope at the end of Cirno's scenario in Hisoutensoku. After some typical spell cards attacks, she causes two of her helper Shanghai dolls to grow twice as big as Cirno and fire wide lasers. Her last attack then causes a single Shanghai doll to grow as big as her house, taller than the screen height and arm it with swords. The swords eventually start shooting lasers themselves.
• After each boss battle in Ape Escape 2, you would capture the boss, except for Yellow Monkey, who just ran away. Later, The Big Bad has his scary speech interrupted by a banana that fell on his head. Looking up, he sees Yellow Monkey, now gigantic, who you have to fight.
• Mega Man:
  • In many of the Mega Man X games, the Big Bad Sigma. Each game ends with you facing off against his multiple forms. His last form is almost always a large robotic body that fills up most of the screen.
    • Noticeably, X2 and X8 avert this; for the former, Sigma instead becomes a floating wireframe of his head, acting as Foreshadowing of his nature as the Maverick Virus, and in the latter he doesn't get a second form, as in a surprise twist he's not the Final Boss of the game.
  • In Mega Man 11, this is the result of Block Man activating his Power Gear upon losing most of his health.
• Supreme Overlord Jergingha in The Wonderful 101. Also the "Unite Big" and "Unite Ultra Platinum" morphs, turning the characters into gigantic figures.
• The Imprisoned in The Legend of Zelda: Skyward Sword is a result of this (and later, the Bishōnen Line, meaning that this monster is the weaker of its forms)!
• Eggman's goal in Sonic Adventure is to do with Chaos, succeeding with each Chaos Emerald the creature houses in its body. Metal Sonic in Knuckles Chaotix and Sonic Heroes is a robotic example.
• This is the resident Monster Clown's whole schtick in Klonoa: Door to Phantomile. He throws something at you, it turns into a giant monster. And later, he does as well.
• The first Melty Blood. G-Akiha.
• At the end of Hexen II, you whail away on Big Bad Eidolon for a while until he calls upon his Chaos Sphere and triples in height.
• The final boss of Purple grows into a humongous Background Boss after you hurt him enough.
• The Abominable Snowbug from Bug does this as a Desperation Attack- it roars while beating its chest and flexing all the muscles in its body, growing to twice its size. Unfortunately for him, his hitbox stayed the same, so Bug could effortlessly jump on him like he could before.
• Kirby in Abobo's Big Adventure.
• World of Warcraft has Prince Kael'thas who, after reaching about half health, will start going mad with power, shattering the giant windows behind him and about doubling in size.
• Smith actually does this in The Matrix: Path of Neo. No, really. All of the different Smiths form one giant Smith as the final boss.
• Dark Souls has Ornstein and Smough, a Dual Boss and That One Boss. The fight has two phases, and when you kill one of them the other absorbs their fallen companion's power. Killing Smough first will cause Ornstein to grow into a giant.
• Inverted by the final bosses of Rockman 4 Minus ∞, the Petit Robot Masters.
• War, the third Horseman of Apocalypse, grows to fifty feet tall for the second half of his boss battle.
• The Mask of Dark Earth in Sly 3: Honor Among Thieves will make anyone it possesses grow twice as large. When it possesses Carmelita, Bentley's attempts to put her to sleep with his darts only causes the mask to grow her to the size of a mountain, resulting in a boss battle with her.
• In reaction to the death of his wife and the public reveal that he is the Abomination, Emil Blonsky, the Big Bad of The Incredible Hulk: Ultimate Destruction, becomes an Abomination twice the size of his previous monstrous form for the final story stages of the game.
• Pokémon:
  • Kyogre from Pokémon Ruby and Sapphire is normally 14 feet tall. When it goes into its Super Mode in the remake, however, its size increases to 32 feet.
  • Boss fights in the Pokémon Rumble series involve using a key to make a Pokémon doll considerably larger than usual.
  • Darkrai becomes giant during the second half of his boss fight in PokéPark 2.
  • In Pokémon Sword and Shield, the Dynamax phenomenon allows a trainer to grow one of their Pokémon to giant size for three turns while fighting in an applicable area, greatly increasing its strength and granting it access to new moves. It can normally only be done in what is known as Power Spots - every Stadium in Galar, the Battle Tower, and within Galarian Pokémon Dens. The story's initial villainous plot centers around the fact that it's happening OUTSIDE of Power Spots, which is a Very Bad Thing. Some species of Pokémon can acquire the ability to undergo Gigantamax instead, which causes it to take on a different form similar to Mega Evolution and be able to use an exclusive G-Max Move.
• Brevon does this to two Freedom Planet bosses: General Serpentine and Mila.
• The final level of LEGO Batman 3: Beyond Gotham is a fight against a giant Superman hypnotized by Brainiac.
• Happens to boss Fernandez in arcade fighter Waku Waku 7. Fortunately, your character is grown as well for the battle, and the stage is a miniaturized city.
• In Lonesome Village, during the final battle, Baran grows to an enormous size to fight Wes on top of the tower.
• In Densetsu no Stafy, Ogura enlarges Doppel, an Evil Knockoff of Starfy, just before Starfy's battle with him.

  • In Ben 10: Secret of the Omnitrix, Ben had to rush across the galaxies to find the Omnitrix's creator, Azimuth, before it self-destructed, tearing the universe apart. Once the threat is neutralized, with Vilgax nearby and ready to kill them, Azimuth turns Ben into an alien bigger than the mountain they're on...who Ben immediately christens, "Way Big".
  • Oddly enough, this is used by a hero in Ben 10: Alien Force. One of Ben's alien forms, Humongousaur, can become larger at will.
  • The Ben 10: Omniverse episode "Showdown" has this happen to Malware.
• In Turtles Forever, the 2003 Shredder becomes humongazoid for the final battle. It's apparently a feature built into his new body from Krang's technology.
  • Krang's suit can be seen doing this in an early episode of the 1987 series, as well as in the video game Turtles In Time. He tries it on 2003 Shredder in Turtles Forever too, but doesn't do so well.
    Krang: "You're not the only one with a molecular amplification bio-suit, y'know!"
    (gets his right arm chopped off and knocked down)
    Ch'rell: "But mine actually works!"
  • Shredder has this done to him by a dark fairy in the Japanese-made Legend of the Supermutants OVA.
• In the Series Fauxnale of Dexter's Laboratory, after Dexter and family have the monster on the ropes, Mandark sweeps in with a laser tank so he can finish it off and get all the credit. However, he's too busy gloating to notice that the monster is absorbing the energy and growing even larger, until it picks him up and eats him (He got better).
• On Muppet Babies (1984), Bunsen tries to defeat a giant dough monster (played by Piggy) with his beast blaster. Only he used his yeast blaster by mistake, and we all know what yeast does to dough... Bunsen then counters this by inflating Gonzo to her size with his weirdo inflator. But then the two start falling in love instead.
• One What If? episode of Futurama has a giant Bender terrorising New New York, so the Professor uses a growth ray on Zoidberg to get them to fight one another.
• The Shushu Rubilax in Wakfu is pretty puny normally (Yugo is taller than him) but each time he gets hit his size increases. Unfortunately, Sadlygrove learns this after he has already rained dozens of blows on Rubilax. Then it gets used against him when Sadlygrove keeps hitting him and causes him to fall down a sinkhole.
• In The Problem Solverz episode "Breakfast Warz", Professor Sugar Fish uses the power of his cereal to become gigantic before the fight with Danny's mom. Because sugar makes you grow big. Crazy big!
• Applied liberally in SWAT Kats, especially when Dr. Viper is in the picture.
• Subverted in Teen Titans in the episode "Mother Mae-Eye"; an army of evil gingerbread men combines to become one giant gingerbread man. Beast Boy responds by turning into a T-Rex and biting it in half.
• Lord Tirek from My Little Pony: Friendship Is Magic's fourth season finale increases in size and strength as he drains ponies of their magic, ultimately growing to 100+ feet tall after acquiring the alicorn magic from Twilight.
• In the Darkwing Duck episode, "Comic Book Capers", D.W writes a comic book based on his adventures which features him dealing with Megavolt and his super remote control that allows him to control all appliances in the city, only for him to be constantly interrupted and people throwing in their own ideas. When Megavolt himself gets his hands on the comic book, he becomes disgusted with the way he's being portrayed and adds in that he uses the remote control to channel the electric company's energy into himself, making him grow ten times his size and dramatic increasing his electrical powers.
  Darkwing: Don't worry, Launchpad. Megavolt may have superior size, he may have superior power, but I have superior intellect!
  (An electric blast from the giant Megavolt's volt gun reduces a nearby mailbox to ashes)
  Darkwing: (Meekly) Then again, let's not undersell size and power.
