History Main / MakeMyMonsterGrow

** In the first game's campaign, one of the enemies is Giant Donkey Kong.

** ''VideoGame/SuperMarioWorld2YoshisIsland'' has giant Baby Bowser, who's big enough that if he gets too close, he destroys the entire castle and Yoshi plummets to his death.
*** In fact, in ''Yoshi's Island'' every single boss except two is [[KingMook 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).
** ''VideoGame/YoshisIslandDS'' has similar for a giant adult Bowser made that way, again by Kamek's magic.
*** Also true for every boss, 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 Mook}}s in that they were already giant when Kamek brings them in) and Baby Bowser.

* In the SeriesFauxnale of ''WesternAnimation/DextersLaboratory'', 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 [[WhatAnIdiot the monster is absorbing the energy and growing even larger]], until it picks him up and eats him (He got better).

* The final level of ''[[VideoGame/LegoBatman LEGO Batman 3: Beyond Gotham]]'' is a fight against a giant Superman hypnotized by [[Characters/SupermanBrainiac Brainiac]].

** The first time you see him in ''VideoGame/SuperMarioGalaxy2'', he's already [[http://youtu.be/AssTyDaiUlo?t=3m13s "HUUUUGE!"]] [[UpToEleven And then he gets EVEN BIGGER for the final battle.]]

* ComicBook/{{Mysterio}} from one of the ''Franchise/SpiderMan'' games does this.

*** 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 [[spoiler: he doesn't get a second form, as in a surprise twist he's ''not'' the FinalBoss of the game.]]

* The final level of ''[[VideoGame/LegoBatman LEGO Batman 3: Beyond Gotham]]'' is a fight against a giant Superman hypnotized by ComicBook/{{Brainiac}}.

* Subverted in ''WesternAnimation/TeenTitans'' 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.

* The climax of ''Venom: The Enemy Within'' limited series has Demogoblin use the power or [[ArtifactOfPower an old enchanted necklace]] to grow to 20 feet, seemingly for the final battle with ComicBook/{{Venom}} and [[Characters/MarvelComicsMorbiusTheLivingVampire Morbius]]. [[spoiler:However, he actually uses it to drown the hordes of evil otherwordly goblins in the river.]]

* [[Characters/MarvelComicsMysterio Mysterio]] from one of the ''Franchise/SpiderMan'' games does this.

* In one ''ComicBook/FantasticFour'' issue, [[Characters/MarvelComicsMisterFantastic 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 360-degree short film ''"HELP"'' made by Justin Lin and Website/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, [[HumansAreBastards a random by-passer steals its "cell phone"]]. The alien gives chase, [[BizarreAlienBiology getting madder and bigger]] as she evades it. Its not an aggressive being, but becomes so in response to aggression, evolving into a [[NighInvulnerability menacing character armored in spikes and muscles]]. Its soon a [[{{Kaiju}} whopping 200ft tall]], before the lady finally [[HeelRealization realizes her error]] and surrenders its phone back. The alien [[BecauseYouWereNiceToMe shrinks back down and happily departs with no further issue]].

* Averted in ''Film/MightyMorphinPowerRangersTheMovie''! The two Ectomorphicon Titans are already giant, and the only "growing" is when Ivan Ooze merges with one of them. (Maligore does make himself grow in ''Film/TurboAPowerRangersMovie''.)

[[folder:Live-Action TV]]
* Plenty of monsters and aliens in the ''Franchise/UltraSeries'' are known to be able to do this; a trope which actually predates ''Super Sentai'' altogether. Here are a few famous users:
** Alien Mefilas in the original ''Series/{{Ultraman}}'' summoned a gigantic illusion of Kemur Man in addition to Alien Baltan and Zarab; he also increased the size of the [=SSSP=] agent Fuji to match them! He can also change his size at will too.
** Yapool, the BigBad of ''Series/UltramanAce''. Initially, it seemed that his giant form was a combination of multiple members of his kind, but later entries in the series clarified that Yapool was but one alien, with the appearance he takes on in his Giant Form essentially being his true face.
** The Dada, courtesy of their size-modifying rayguns.
** Most Ultras in the franchise can change size at will, and have no real upper limit to how large they can be. Series/UltramanMax is an especially unusual example, in that several of his fights involved him growing much larger than the standard 50 metres height most Ultras tend to stick to, in order to fight even larger monsters.
* ''Franchise/SuperSentai''/''Franchise/PowerRangers'' made this trope famous. Whenever the Rangers defeated the MonsterOfTheWeek, eight times out of ten the BigBad of the season would either grow or resurrect it at giant size for the Rangers to fight in their [[HumongousMecha Mecha/Zords]]. Each villain had a different method for doing this:
** The first Mecha using Super Sentai, ''Series/BattleFeverJ'', averted this. Starting with Episode 5, the monster of the week would call a giant robot duplicate of itself. In the early episodes, Battle Fever would have to defeat the monster while dodging attacks from the robot, then get in their own mecha to defeat it. In later episodes, sometimes the monster called its robot as it died, and sometimes both battles happened simultaneously.
** The Vader Monsters of ''Series/DenshiSentaiDenziman'' were the first to play this straight, as they can enlarge themselves by manipulating their cellular structures.
** In ''Series/TaiyouSentaiSunVulcan'', the Mongers are installed with the "Expansion Program". The Monger will announce "Giant monger!" and grow on its own (typically right after the team finisher, natch).
** In ''Series/DaiSentaiGoggleFive'', the defeated Synthetic Beasts would get hit by the "Refresh Power" beam, and then sent into HumongousMecha copies of themselves called Kongs to pilot, similar to Battle Fever J. However, this exact happening didn’t occur until five episodes in and the robots those monsters piloted previously weren’t replicas but unrelated designs made by Deathdark scientists.
** ''Series/KagakuSentaiDynaman'' has two methods of doing this: the Evolution Beasts undergo "Big Bang Process" when they're defeated, while the Mechavolution Beasts are enlarged by the Gran Gizmo's "Big Bang Beam".
** ''Series/ChoudenshiBioman'' averted this again: they don't have growing monsters. Instead, they have five recurring human-sized monsters, and a separate {{Robeast}} serving as the series' MonsterOfTheWeek (occasionally piloted by one of the three generals).
** Gyodai of ''Series/DengekiSentaiChangeman'' can resurrect and enlarge dead Space Beast Warriors by firing an enlargement beam from his eye. The monster whose purpose is to enlarge other monsters would later become a staple in Hiroshi Soda's Sentai, and would rarely have any other job or much personality, being a more animal-like creature who seems to operate mostly on instinct. Using its grow method tires it out, requiring it to recharge until next time, hence the inability to send and grow multiple giants at once. In Gyodai's case in particular, one episode's scheme-of-the-week was a plan that would result in giving him the ability to repeatedly use his grow ray without tiring. Naturally, he didn't keep that ability beyond that episode.
** In ''Series/ChoushinseiFlashman'', the giant mutant jellyfish called Kuragen is summoned to enlarge a Genetic Beast by expelling the energy from its body. Doing so causes it to shrink (in a case of LiquidAssets).
** In ''Series/HikariSentaiMaskman'', Okelampa would show up to resurrect and enlarge dead Dogglers with an energy shower. This can be only used OncePerEpisode, since Okelampa would get tired quickly after doing it.
*** In the finale, Earth Emperor Zeba enlarged himself by absorbing the Aura Power from the Maskmen's Jet Cannon.
** Guardnoid Gash of ''Series/ChoujuuSentaiLiveman'' carries the Giga Phantom cannon to rebuild and enlarge the Brain Beasts. However, as a side effect of using the Giga Phantom, the Brain Beasts [[ClippedWingAngel can't use their special powers]].
** In ''Series/KousokuSentaiTurboranger'', the Bohma generals can summon magical tornadoes to enlarge the Bohma Beasts. However, each member has a different method of summoning it.
** ''Series/ChikyuuSentaiFiveman'' zig-zags this. Similar to ''Goggle V'', a Gorlin (a giant robot purchased by the Silver Imperial Army Zone for 100,000 Dolyens per unit) is summoned to absorb the Galactic Warriors. Unlike the Kongs, instead of being HumongousMecha copies, the Gorlin start out having a blank doll-like appearance (making it resemble the Michelin Man and/or the Stay Puft Marshmallow Man) before assuming the appearance of a Galactic Warrior upon absorption. They do this by way of shooting a beam that converts the Galactic Warriors into energy form, then absorbing the energy to replicate the appearance of the assimilated alien, using the genetic material of what was absorbed. That being said, Gorlins can't absorb a Galactic Warrior if they're killed off, as [[https://www.youtube.com/watch?v=GMs5GY_PeIs this embarrassing incident]] demonstrated. Moreso, those absorbed by Gorlins can actually free themselves if reminded who they are, as they apparently lose their free will after being absorbed.
*** First Captain Chevalier would later use a Black Gorlin, which cannot absorb Galactic Warriors but is more powerful than the regular version. It was more of a giant attack robot than a method of growing monsters, however.
** In ''Series/ChoujinSentaiJetman'', Dimensional Beasts/Jigenjuu are created when a Dimensional Bug/Jigenmushi possesses an inanimate object, but the bugs serve an extra purpose. When a Dimensional Beast is killed in combat, its Dimensional Bug is thrown from [[DefeatEqualsExplosion the monster's explosion]], and proceeds to grow ''itself,'' assuming the appearance of the dead Dimensional Beast while gaining its powers (though if the bug is destroyed alongside its Dimensional Beast, the monster can't be brought back). Alternately, Dimensional Bugs can work in that, when a Dimensional Beast is close to defeat, that it releases energy to rejuvenate and enlarge that Dimensional Beast (as observed with Road Dimension/Rodo Jigen, whose Dimensional Bug gigantified him before the Jetmen could finish him off). The same rules also apply to the Bio-Dimensional Beasts/Baio Jigenjuu and their Bio-Dimensional Bugs/Baio Jigenmushi (which were differently shaped and colored compared to the normal Dimensional Bugs). Some Dimensional Beasts, such as Fighter Dimension/Faita Jigen and House Dimension/Hausu Jigen, are already giants due to their Dimensional Bugs possessing large inanimate objects.
** ''Series/KyoryuSentaiZyuranger'' has [[BigBad Witch Bandora]] chanting the magic spell, "Evil spirits sleeping beneath the earth, give your power to Dora [Monster]!" before throwing her Dora Scepter to Earth. The Dora Scepter, upon reaching ground, would output energy to make a crack in the ground to actually release sleeping ghosts within the soil. The evil spirits would converge on the Dora Monsters, the donation of strength proceeding to regenerate and enlarge them.
*** This would carry over to the first season of ''Series/MightyMorphinPowerRangers'', with Rita Repulsa and her magic wand. There's no mention of ''spirits'' being used to grow her monsters, but her wand still plays a role, apparently being the source of the energy that the monsters use to grow. Rita's chant in Sentai footage is changed to make the [[TropeNamers Trope Namer]]: "Magic wand, make my monster grow!"
*** Bandora/Rita could also do this to Grifforzer/Goldar, Lamie/Scorpina, and Burai/Tommy as well, and they could return to normal size.
** In ''Series/GoseiSentaiDairanger'', the Gorma would usually bring Enlargement Bombs in case things are going south for them. They work like grenades in that the Gorma using them have to remove the pin and toss them on the ground at their feet. It's not clear as to how they work, but it's possible that the bombs are magic, as when they are detonated the Gorma rise from the resulting explosion at massive size (the footage would often show the explosion reversing, implying the Gorma were absorbing the energy of the bomb to fuel their growth). ''Series/MightyMorphinPowerRangers'' used the same method in the second season, except Lord Zedd would personally send the bombs to his monsters by throwing them down to Earth.
*** In ''Dairanger'', the bombs are shown to be something of a disadvantage in that there is a window of time to stop the Gorma from using the device. It's even defied in an episode where [[MonsterOfTheWeek Purse Priest/Pursehead]] tries to use his Enlargement Bomb, but is blocked by the heroes by throwing their staves to form a cage to prevent him from doing so. That said, ''Dairanger'' also has some humorous awareness regarding growing. In one scene, [[TheBrute Major Zydos]] whips out an Enlargement Bomb and proceeds to toss the pin on the ground instead of the bomb, right before realizing his mistake and throwing the real thing. In another instance, [[MonsterOfTheWeek Lipstick Songstress/Lipsyncher]] gets so pissed at having her "perfect" face scratched that she whips out an Enlargement Bomb (clearly, she has ''no'' regard for the unwritten rule that you're only supposed to grow when you're losing). You can even see her [[{{Mooks}} Cotpotros]] running away ''before'' she activates it, not wanting to be squished by her soon-to-be-giant feet! [[note]]This wasn't seen in MMPR because of the Dairanger costumes and Cotpotros not being used; MMPR was still using the Zyuranger outfits and Putty Patrollers.[[/note]]
** ''Series/NinjaSentaiKakuranger'' has the Yokai call for an enlargement jutsu. This results in them being struck with lightning (which is made from humanity's rage, hatred, and sorrow) from the Yokai Cloud to enlarge themselves.
*** The third season of ''Series/MightyMorphinPowerRangers'' changed this to Rita and Zedd crossing their staves to generate magical lightning.
** ''Series/ChourikiSentaiOhranger'' and ''Series/PowerRangersZeo'' gives us Acha/Klank and Kocha/Orbus, who are more than just the royal butlers. Whenever a Machine Beast has been defeated, Acha/Klank pulls out a cord on Kocha's/Orbus' side, extending it and then swinging her/him over his head (in ''Ohranger'', Acha and Kocha yelled each other's names in "Marco Polo" fashion during the swinging, while in ''Zeo'', Klank announced, "And around and around and away we go!") until he builds enough momentum to toss Kocha/Orbus at the Machine Beast. Kocha/Orbus would then latch on and proceed to inject a special, glowing fuel into the Machine Beast. In some later instances, though, Kocha/Orbus uses a close-range beam instead. Or both: fuel first, then beam, with the beam supposedly being an energizing catalyst for the fuel. Regardless of how, Kocha/Orbus' donated energy serves to empower the Machine Beast, causing them to re-pixelate at monstrous size.
** Parodied (all the time) in ''Series/GekisouSentaiCarranger''. In order for the Gorotsuki (Bowzock's [[MonsterOfTheWeek Monsters of the Week]]) to grow, they must eat imo-youkan.[[note]]a yellow cube-shaped food made from jellied sweet potatoes[[/note]] Due to a unique effect the imo-youkan has on their biology, it causes them to glow red and blow steam from their nostrils before growing to massive size. Said food must be freshly hand-made from a certain store (Imocho). Factory-made and/or expired imo-youkan makes the Gorotsuki shrink (when this happens, they glow blue while blowing steam).
*** As Inventor Grotch found out in Episode 4, an expired imo-youkan can temporarily enlarge the consumer before reverting them back to its original size. President Gynamo [[ChekhovsGun took advantage of this]] in the finale, where he threw expired imo-youkan into the mouth of a giant [[BigBad Emperor Exhaus]], causing the latter to weaken, revert back to his original form, and shrink to human-size for the Carrangers to finish him off.
*** However, in ''Series/PowerRangersTurbo'', Divatox would have her men launch enlargement torpedoes instead. They still turn red and blow steam, though.
** In ''Series/DenjiSentaiMegaranger'', [[BigBad Dr. Hinelar]] ran an experiment on [[TeamPet Bibidebi]] in Episode 3, which gave him the ability to infect Nezire Beasts (and later, Psycho Nezilars) with an enlargement virus. Whenever a Nezire has been defeated by the Megarangers, he beams down, cries out "Enlargement Virus Injection!", and bites the Nezire Beast/Psycho Nezilar, infecting their DNA (with little, Bibidebi-shaped molecules) and causing them to enlarge. In one instance, [[TheHero Mega Red]] completely obliterated [[MonsterOfTheWeek Lion Nezilar]], but Bibidebi improvised another growth process by sucking the flames and smoke remaining from the destroyed monster's explosion into his mouth, then blowing it out as a fine mist to rematerialize Lion Nezilar at titanic size.
*** ''Series/PowerRangersInSpace'' replaced this with Astronema giving the command for the Dark Fortress to fire a "Satellaser" ray, which flashes a bright green scanning beam upon the place where a monster fell to enlarge them. It was [[LampshadeHanging lampshaded]] by Elgar once, when he muttered "Here we go again" while firing the beam.
** ''Series/SeijuuSentaiGingaman'' has the Majins consuming an enlargement potion called "Balba-X" (or Balban Extract) to grow. However, the Balba-X is only used as a last-ditch attempt to kill the Gingamen, since drinking it would slowly kill them (or according to some translations, drastically shorten their lifespan).
*** In ''Series/PowerRangersLostGalaxy'', we saw ''a'' grow potion in a few early episodes, but in reshot American footage -- in ''Gingaman'', the monsters would drink them out of various styles of alcohol containers, to go along with the whole "pirate" motif; obviously that wouldn't fly by the censors, so in the American footage the monsters drink a green liquid from a science-y looking beaker/flask. But the green elixir only appeared in five episodes, and after that, the monsters would seem to automatically grow after being hit with the team finisher, as if it directly caused them to enlarge (presumably because of the show's TroubledProduction, they couldn't spare the time/budget to reshoot all these scenes so they simply opted to leave them out).
** In ''[[Series/KyukyuSentaiGoGoV Kyuukyuu Sentai [=GoGoFive=]]]'' and ''Series/PowerRangersLightspeedRescue'', Pierre/Jinxer throws Regeneration Cards to resurrect and enlarge Psyma Beasts/Demons. The Golem Cards have the same function as the Regeneration Cards with the addition of giving the enlarged Psyma Beasts/Demons more powerful and armored forms.
*** Granted, in ''PR'', they didn't bother to explain the distinction. In [=GoGoV=], the Golem Cards were created from the remains of Magma Golem/Magmavore, the first monster to have a second form. PRLR isn't really ''harmed'' by leaving that out, but it's a nice little bit of worldbuilding that would've been nice to keep.
** ''Series/MiraiSentaiTimeranger'' and ''Series/PowerRangersTimeForce'' have the same method but with different reasons: In ''Timeranger'', the Londerz Prisoners are flash-frozen and shrunk down to the size of action figures. When they're released from confinement, they have to wear a Depression Seal in order to maintain their normal size. Removing the seals -- whether the prisoners intentionally do this, or by an unintended attack from the Timerangers -- would cause a "rebound": a side-effect of the compression process in which they become gigantic. In ''Time Force'', the mutants have natural DNA Patches, and removing them exposes their DNA, causing them to grow and increase in strength. In both cases, when they are defeated at giant-size, they are reverted back to their compressed states. However, a monster can be defeated and re-compressed while human-sized.
** In ''Series/HyakujuuSentaiGaoranger'' and ''Series/PowerRangersWildForce'', [=TsueTsue=]/Toxica would spit Org Seeds from her staff to resurrect and enlarge dead Orgs while reciting an incantation. In ''Gaoranger'', [=TsueTsue=] chants, "Org Seeds, please allow the fallen to regain their enormous wicked power! Ogres come in! Blessings go out!" In ''Wild Force'', Toxica's magic words are "Evil spirits of toil and strife, give this fallen Org new life!".
*** Typically, the seeds are fired into the green goo left behind by a dead Org. But they're also consumable, as seen when Yabaiba/Jindrax enlarged himself by eating them to aid his brother Juggling Org/Juggelo. He also forcefully fed them to Animal Tamer Org.
*** Yabaiba/Jindrax would sometimes replace [=TsueTsue=]/Toxica as the monster enlarger if either her staff was broken, or she wasn't around.
*** In ''Gaoranger'', Highness Duke Org Shuten used a special ritual to grow by stabbing himself with [=TsueTsue=]'s staff. In ''Wild Force'', however, Retinax simply grows all by himself.
*** Duke Org Rouki had his own Org Seeds, which are referred to as "Wolf Seeds". In ''Wild Force'', however, Zen-Aku doesn't use them on his Orgs.
*** As a result of absorbing the Thousand-Year Evil, Highness Duke Org Ura can enlarge himself after [=GaoRed=] used the newly-acquired Falcon Summoner on him. In ''Wild Force'', Master Org enlarges Nayzor with Org Seeds instead, as Nayzor had been destroyed beforehand.
*** Highness Duke Org Rasetsu used a special bug to sabotage the Gaorangers' G-Phones before eating it to enlarge himself. This was defied in ''Wild Force'', where Mandilok was quickly killed off by Master Org (as payback for trying to kill him earlier), before he could get the chance to fight the Wild Force Rangers at all.
*** Ultimate Org Senki, the FinalBoss of the series, wastes no time enlarging himself by using [=TsueTsue=]'s new staff after being formed from the three Highness Duke Orgs' remains. On the other hand, Master Org in his ultimate form can grow without it (though this was mainly due to Jindrax and Toxica pulling a HeelFaceTurn earlier, which Yabaiba and [=TsueTsue=] never did).
** ''Series/NinpuuSentaiHurricaneger'' has '''three''' ways the villains could make the MonsterOfTheWeek grow to giant size; depending on which of the generals the monster was in the service of. Wendinu either had to launch a mystical scroll onto the battlefield (for Chuuzubo's Bionin Corps), summon a missile that transformed into a blank "Copy Giant" robot that would scan the monster's remains and become a [[ExactlyWhatItSaysOnTheTin gigantic copy of the monster]] (for Sargain's Mechanic Corps, which was similar to the ''Fiveman'' method), or physically hurl a size-changing mask out there (for Satarakura's Mask Corps).
*** ''Series/PowerRangersNinjaStorm'' edited out Zurgane and Shimazu's enlargement methods while keeping Choobo's for enlarging monsters (though a device similar to Zurgane's "Copy Giant" device is used to summon enlargement scrolls instead of Choobo's bazooka).
*** There is a great deal of [[LampshadeHanging lampshading]] regarding monster growing in ''Ninja Storm'', actually. On one occasion, the BigBad Lothor [[BreakingTheFourthWall looks directly at the screen]] and says, "What did you expect? He wasn't going to get smaller!" Another time, when Marah and Kapri first recruited Shimazu, Marah says, "What's the worst that could happen? They blow him up, we grow him big again, they blow him up again and we grow him big again and they blow him and we grow him and--" and Lothor cuts them off with, "I know [[StrictlyFormula the formula]]!" On another occasion, Lothor had just sent ''several'' monsters, and decides to make them ''all'' grow. Lothor tries, gets an error, and Zurgane reminds Lothor that he'd been too cheap to pay for the memory upgrade that would let multiple monsters grow at once. Lothor grumpily tells him to make just one grow.[[note]]This was a case of LeaningOnTheFourthWall, as Disney reduced the budget and said no more than one giant monster could be used in a battle.[[/note]]
*** Amusingly, in one ''Hurricanger'' instance (Episode 25, to be precise), the particularly tiny [[MonsterOfTheWeek Vamp-Iyan]] is defeated and gets enlarged... to the same size as a regular human. He is promptly taken out a second time, and is ''then'' grown to the usual giant size.
** The Trinoids (mutants made from an animal, a plant, and an inanimate object) of ''Series/BakuryuuSentaiAbaranger'' are implanted with Life Berries, so if they're killed off, the Life Berries will turn into a giant rain cloud to resurrect and enlarge them. Averted with Giganoids, who are already giants upon creation due to being created from Voffa's musical notes instead of Mikela's paintings.
*** ''Series/PowerRangersDinoThunder'' retains the enlargement rain cloud except it's summoned from Mesogog's "Hydro-Regenerator". The Giganoids are introduced in human-size here (Mesogog's monsters all get made in the same "[[LegoGenetics Geno-Randomizer]]" chamber in his lair) and get grown by the Hydro-Regenerator. (Sometimes we don't see them grow; many were small when created but giant upon encountering the Rangers. It's assumed that the same method is used.)
** {{Averted|Trope}} in ''Series/TokusouSentaiDekaranger'' and ''Series/PowerRangersSPD'', where the enemies don't grow. Like the Dekarangers/SPD Rangers, whenever they need to escalate things, they would pilot a [[HumongousMecha Heavy Industrial Machine]] provided by Rainian Agent Abrella/Broodwing. There are also a few occasions where the villains grew instead, never using the same method. On one occasion, Abrella/Broodwing even summoned a bat to bite a suspected Alienizer/alien criminal, which caused him to enlarge.
** ''Series/MahouSentaiMagiranger'' and ''Series/PowerRangersMysticForce'' has Wolzard/Koragg casting an enlargement spell. Vancuria/Necrolai, during the time she is given Wolzard/Koragg's magic, uses a phone (basically the Rangers' changing device with Wolzard's color scheme) to do the deed. Here's where the two versions diverge: Meemy in Magiranger chants a spell like Wolzard, but monsters used by his PR counterpart Imperious could grow on their own.
*** Interestingly, the Infershia Pantheon/Ten Terrors are naturally giants, and could make themselves human-sized at will. They'd go back to their natural sizes for the last round.
** Each ''Series/GoGoSentaiBoukenger'' and ''Series/PowerRangersOperationOverdrive'' villain had their own enlargement methods, whether by Ryuwon/Moltor's enlargement gun, Gekkou/Kamdor's sutras, or skin shedding from the Ashu/Fearcats.
*** However, Gajah/Flurious' Godom Giant Gods, Ryuwon/Moltor's Daijaryu and the Ashu/Fearcats' Quester Robos are already giants. Some Precious can also become monsters and enlarge themselves at will.
** In ''Series/JukenSentaiGekiranger'' and ''Series/PowerRangersJungleFury'', enlarging is a ''martial arts technique.'' The Akugata Beast-Men from Gekiranger are able to do it at will [[CallingYourAttacks through the recital of the ability]] ("Jashin Goten Hen!", which roughly translates to "Wicked Body Overpowering Heavenly Change"). In Jungle Fury, meanwhile, the Rinshi Beasts must collect enough human fear to access the technique. The Rangers counter this by making their mecha out of their [[KiManipulation Ki Attacks]].
** The Banki Beasts of ''Series/EngineSentaiGoOnger'' are installed with a powerful fuel called Bikkurium, which is provided by Kitaneidas and installed in case things go south for the Banki. Upon defeat, the Banki can enlarge themselves by releasing the Bikkurium into their systems and uttering the command "Industrial Revolution!".
*** At some point in [=GP17=], Rock Blast/Happa Banki dramatically shouts the usual growth command... and nothing happens. Turns out Go-On Gold had removed the monster's Bikkurium module during the battle!
*** Due to Hiramechimedes installing himself with a hundred times the usual amount of Bikkurium needed for a normal enlargement, he can enlarge himself through "Big Industrial Revolution" as Detaramedes.
*** [=GP24=] has Urameshimedes (actually Hiramechimedes as a ghost) possessing Bakki to enlarge and become "Hirameki Banki".
*** In [=GP31=], Lumbiaco can grow by simply hearing noises and male sounds and can only be shrunk back to its original size by hearing female sounds.
*** Kireizky and Chirakasonne used a more powerful fuel called Dokkurium for their "Super Industrial Revolution", while Yogoshimacretein had an even ''more'' powerful variant called "Third Industial Revolution".
*** ''Series/PowerRangersRPM'' retains the "Industrial Revolution" process, but the Bikkurium is replaced with Venjix's "Power Download" to enlarge the Attack Bots. Venjix, (or one of his generals, or the Attack Bot itself, but usually Venjix) will say "Begin the download, now!" Granted, we still see Bikkurium flowing through the circuits of the Attack Bots, but it is not referred to as such (you could assume this is revitalizing fuel or something like that).
** In ''Series/SamuraiSentaiShinkenger'' and ''Series/PowerRangersSamurai'', all Gedoshu/Nighloks have two lives: if a human-sized Gedoshu/Nighlok is killed off, it's immediately reincarnated as a giant (or in the Nighlok's case, a "megamonster"). Takeru/Jayden knew this already, having fought them longer than the others. This is their ''only'' growing method; in one episode, a monster whose giant form has a big shield had finally powered up enough to use it, so Juzo/Deker and Dayu ([[NamesTheSame same name in both versions]]) are sent to kill it so its second life can kick in.
*** Shitari/Octoroo gave up his second life so Oborojime/Gigertox could have a ''third'' life, becoming an even bigger CGI horror that didn't resemble his original form at all. This would come back to bite Shitari, who is later KilledOffForReal at the hands of the Gokaigers in a team-up that never happened in ''Power Rangers''.
*** The ''Shinkenger'' crossover in ''Series/KamenRiderDecade'' averts this by virtue of StoryBreakerTeamUp, though: When the Ayakashi Chinomanako [[spoiler:stole Daiki's Diendriver and transformed into a corrupt version of Kamen Rider Diend]], his biology was somehow altered, meaning that it now had only one human-sized life. Really though, this was done mainly because Kamen Riders didn't start having their own HumongousMecha on a regular basis for another five seasons.[[note]]However, there are Kamen Riders who face giant threats more often than others, though not OncePerEpisode. Take ''Film/KamenRiderJ'' and ''Series/KamenRiderHibiki''. The former makes himself grow whereas the latter, in spite of the size of his enemies, '''doesn't'''. ''Series/KamenRiderDenO'', ''Series/KamenRiderKiva'', and ''Series/KamenRiderDouble'' fight giant monsters semi-regularly, using their weapon-laden transforming CoolTrain, dragon castle, and bike that can attach to many other monster-busting vehicles, respectively. ''Series/KamenRiderOOO'' often doesn't ''need'' such things to deal with giant threats, taking out the first with a sword slash in finishing mode. It's too bad we ''didn't'' get to see Decade show the Rangers that you don't need giant robots to deal with giant beasties.[[/note]]
*** [[spoiler:Diend does this to Decade[[note]]Kinda; it's not that Decade grows per se, it's that Diend used a Final Form Ride to fuse Decade with the giant ''Film/KamenRiderJ'' into a humongous Decade[[/note]]]] in ''All Riders vs. Dai-Shocker'' as the final trump card against [[Series/KamenRiderX King Dark]], the last man standing of [[LegionOfDoom Dai-Shocker]] after its leaders are finished off.
** ''Series/TensouSentaiGoseiger'' and ''Series/PowerRangersMegaforce'' has Buredoran/Brajira/Vrak calling his Bibi Bugs/Zombats to attach themselves to a monster and initiate the enlargement process. Buredoran/Brajira/Vrak and Mons Drake/Malkor can also enlarge themselves by using a single Bibi Bug/Zombat as well.
*** Because the Matroids/robots are not organic beings, Metal Alice (same name in both versions) has to convert the Bibi Bugs/Zombats into Bibi Nails/Zombolts to enlarge them.
** ''Series/KaizokuSentaiGokaiger'' and ''[[Series/PowerRangersMegaforce Power Rangers Super Megaforce]]'' has MadScientist Insarn/Levira firing an enlargement ray from the Gigant Horse/Armada's mothership on the Action Commanders. In ''Power Rangers'', where this and the previous series are connected, the Maximizer is noted to have the advantage over the Zombats of being able to grow multiple targets at once.
*** It also lampshades the concept in one episode, where the BigBad impatiently fires the growth ray early, causing Gokai Green to remark "He grew even though we haven't beaten him yet! Can he do that?!" In another episode, after the monster grows, Gokai Red [[DeadpanSnarker snarks]] "We weren't going to skip this part, were we?" Yet another episode has a monster that has the ability to grow as a latent power -- as well as shrinking, which lets it get into the team's mecha and wreak havoc.[[note]]In ''Super Sentai'', the once in a rare blue moon that the monster grows before being destroyed first almost always gets commented on. Not so in ''Power Rangers'', because the first several seasons happen to be based on the few sentai where a still-living monster being grown mid-battle is the norm. To a Sentai fan, "the monster must be destroyed first" feels like this ironclad rule that got broken a few times ''long'' ago 'cause TheNineties were ''really'' weird. Sentai has ''more than one'' instance of the monster having to be killed so it can be revived as a giant, and in ''Gokaiger'', the BigBad's generals actually tried to ''physically hold him back'' from hitting the grow ray before he's "supposed" to because the fact that ''that's just not how it's done'' overrode their usual loyalty![[/note]]
*** ''Gokaiger'' also averts it in a couple of special instances: [[DiscOneFinalBoss Commander Warz Gill/Prince Vekar]] has a self-styled HumongousMecha, as does Insarn/Levira. [[TheRival Basco]] has Giant Battle Pseudo-Lifeforms, which he summoned by opening the compartment in Sally's chest whenever he wants to {{Troll}} the Gokaigers even more. And late in the series when [[GreaterScopeVillain Emperor Ackdos Gill/Emperor Mavro]] shows up, enlarging monsters became less common and finally stopped entirely after Insarn/Levira is killed off (though we do get some mecha battles later because at that point, the invasion fleet has arrived).
** As with ''Series/BattleFeverJ'', the Metaloids/Robotrons and Megazords/Gigadrones aren't the same critters in ''Series/TokumeiSentaiGoBusters'' and ''Series/PowerRangersBeastMorphers''. As such, (also just as in ''Battle Fever J'') while the Megazord/Gigadrone ''usually'' arrives just after the Metaloid/Robotron is killed off, there are nearly as many times when the team must split up as some fight the Metaloid/Robotron on the ground and the rest fight the Megazord/Gigadrone in their own HumongousMecha, or the Megazord/Gigadrone must be fought first while the Metaloid/Robotron carries out the evil plot du jour in hiding. Monsters in this series are created from Earth objects, and on one occasion, a robot based on a monster is ''turned into a monster itself,'' and soon ''a new robot based on it arrives''. At one point you've got a robot ''within'' a monster ''within'' a robot. [[MindScrew Hurts your head, doesn't it?]] [[spoiler: This "Megazord Zeta" in turn is possessed by [[BigBad Messiah]] and takes on yet another form!]]
*** Played straight with Rhino Doubler... strangely. Rhino Doubler is a monster tied to the lore of ''Series/SpaceSheriffGavan''; the episode is a tie-in to the then-upcoming ''Film/SpaceSheriffGavanTheMovie'' about Gavan's [[LegacyCharacter successor]]. Monsters in ''Gavan,'' just like monsters in ''Go-Busters,'' do not grow: in ''Gavan'' and several other ''Series/MetalHeroes'' series, the "monster is against the ropes and escalates the battle" move is transporting the whole battle to a bizarre, trippy PhantomZone area where monsters are three times stronger. So, when ''Go-Busters'' {{Dragon}} Enter tries to turn the recently-destroyed Rhino Doubler's "Makuu Space" transporting device into a monster, the unexpected-even-by-Enter result is a giant Rhino Doubler in the ''only'' instance of typical "Make My Monster Grow" in all of ''Go-Busters'' or ''Gavan''. Rhino Doubler's ''Beast Morphers'' counterpart Ryjack, who is not related to ''Gavan'''s counterpart Captain Chaku, but still maintains the oddball monster status by being a criminal alien from outer space, also provides one of the series' very few moments of growth by carrying an enlarging device amongst his arsenal of gadgets which he uses on himself. (Unlike his ''Go-Busters'' counterpart, Evox went giant after getting a physical body. Sadly, we didn't see a proper giant battle with this body. However, he gets a giant battle in a second, different and naturally giant body later).
** In ''Series/HikoninSentaiAkibaranger'' the eponymous team wait until sunset for [[OverlyLongName Shibuyaseitakaawadachisouhidenagaaburamushi]] to grow into a giant after he is destroyed, just like how they "always" do. It never happened. [[labelnote:note]] It's been observed that the first MonsterOfTheWeek faced by the rangers is seldom enlarged, most likely because in most series the mechas are introduced in the second episode. Which was the case for ''Series/HikoninSentaiAkibaranger''.[[/labelnote]]
** ''Series/ZyudenSentaiKyoryuger'' has a literal example. Luckyuro can enlarge the Debo Monsters using "water" (a fluid made from Deboth's cells) in a ''watering can''. They can also be shrunk back to their original size if they're hit with his magical tennis balls that ''absorb away'' the water.
*** In later episodes, some Deboth Army generals can enlarge themselves at will by using the Deboth Super-Growth Cells. The Neo-Deboth Army used this as well in ''[[Series/PowerRangersDinoForcebrave Kyoryuger Brave]]''.
*** ''Series/PowerRangersDinoCharge'' replaced this with Sledge commanding a Vivix to fire a "Magna Beam" from his spaceship. The same beam can restore a monster to small size.
** In ''Series/ResshaSentaiToQger'', the Shadow Creeps would automatically enlarge themselves by absorbing the darkness they've gathered in a last-ditch attempt to kill the [=ToQgers=].
*** Averted ''yet again'' with the Kuliners, which are basically {{Transforming Mecha}}s brought out by the Shadow Line to even the odds against the [=ToQger=]'s {{Humongous Mecha}}s. General Schwarz, Marchioness Morc, and Emperor Z have their own AceCustom Kuliners as well.
*** During the "Spring Vacation" crossover special with ''Series/KamenRiderGaim'', a Lion Inves ate two Helheim Fruits, causing it to grow in an instant.
** Kyuemon of ''Series/ShurikenSentaiNinninger'' can enlarge the Yokai by using the Kibaoni Nin Shuriken attached to his mallet. The Kibaoni Nin Shuriken also works on other beings too, as seen when Mataneko used Kyuemon's mallet in an attempt to attack Takaharu, only to end up enlarging him by accident instead. Also, a team-up shows that the mallet works just fine on Roidmudes from ''Series/KamenRiderDrive.''
*** Starting from Shinobi 33 onwards, Masakage takes over Kyuemon's job in enlarging the Yokai after the latter is presumed dead as a result of Gekitotsu Dai-Oh destroying his HumongousMecha (though in reality, Kyuemon went into hiding after that incident).
*** Some Yokai are capable of enlarging themselves without the need of the Kibaoni Nin Shuriken. Among these Yokai are Nue, Juza, Mangetsu, Shuten-doji, and the above Masakage.
*** ''Series/PowerRangersNinjaSteel'' had the same "enlargement beam from the villains' spaceship" method as ''Super Megaforce'' and ''Dino Charge'' by having Cosmo Royale fire a beam from the Warrior Dome ''if'' the Galaxy Warriors audience demands it. We did still get a "Red accidentally gets embiggened" battle, as that episode took place when the ship had been damaged and Cleocatra had a growth device installed into her time controller (don't ask, it's complicated). A tussle over it results the same battle from ''Ninninger''.
** Lampshaded by the Deathgaliens in ''Series/DoubutsuSentaiZyuohger'': they have medal slots somewhere in their bodies, so Naria can enlarge them by inserting Continue Medals on their medal slots and they would thank her for it. Like an arcade game, if a [[MonsterOfTheWeek Player]] loses, you "insert a coin to continue".
*** Quval and Azald needed more than one Continue Medal to enlarge. In Azald's case, inserting three Continue Medals directly into his core causes him to become mindless. Banglay and Naria can also enlarge themselves by consuming a Continue Medal.
*** The crossover episode with ''Series/KamenRiderGhost'' has a special guest monsters in the form of Shiomaneking from the original 1971 ''Series/KamenRider'', who had a Continue Medal ''shoved into his throat'' as he did not have a medal slot, while Naria raised her concerns of whether such an impromtu method would actually work. ''It still works as expected''.
** Each Daikaan in ''Series/UchuSentaiKyuranger'' has an Enlarge Inrou [[note]](a traditional Japanese pocket box used for storing, among other things, medicines)[[/note]] that automatically revives and grows them if they die, but it's a one-time use item as they burst apart upon usage. However, some don't use them, instead opting to use Moraimarz in fighting mode (the Inro can still be seen on them; [[FridgeLogic you'd think when they go down with their Moraimarz robot]], the Inro would ''then'' enlarge them for a round three, but that never happens.) Vice-Shoguns get special treatment in this regard - a golden idol on their right shoulders that allow them to do this ''repeatedly''. Deathworms naturally have the ability to change size at will.
*** An unusual variant happens when two of the Kyurangers shrink down to fight against a tiny size monster called Microtsuyoindaver inside somebody's brain. The first time he is killed, he grows to the size of a normal monster. The second time he is killed, instead of growing a second time to giant size, he manifests a giant copy of the person he was controlling with his dying breath.
** ''Series/KaitouSentaiLupinrangerVsKeisatsuSentaiPatranger'' has Gauche performing "surgery" on a dead Gangler's "safe" remains by firing an enlargement serum from her Gros Caliber at it. Every Gangler has a safe on its body that lets it use the ArtifactOfDoom of the week: the safe is also its core. If the safe isn't completely destroyed, neither is the monster, and it's Gauche's grow juice to the rescue. Ganglers with multiple safes require a dose per safe.
*** In one episode, the Patrangers seemingly destroy a monster before the Lupinrangers can retrieve the treasure in its chest, resulting in them becoming despondent (their FetchQuest requires them to [[GottaCatchEmAll collect all the treasures the Gangler have]]). However, they soon realize that no giant version of the monster appeared. Both teams eventually connect the dots on how weird for Gauche to not show up and revive/enlarge it, and deduce that it must have escaped before the final blow was actually struck.
*** One of the Ganglers is revealed to be able to grow giant on his own power, and is larger and more powerful then those enlarged by Gauche and neither team's Kaiser is powerful enough to defeat it, prompting Goodie, the sentient mecha both teams' mechs merge with, to basically force them to work together and combines with all the mechs, including Lupin/Patran X's entire solo mecha, into Good Cool Kaiser VSX, made up of 11 different mechs at once.
*** Episode 29, being a clip show, has no real monster, just a modifed Poderman, one of this season's footsoldiers, with a safe for a head and a giant hand. It's killed fairly quickly and not enlarged and when Goodie shows up, he's surprised he's not needed, prompting his flashback about the giant robot battles.
*** Also lampshaded in episode 30, as the monster is so smelly, the fight is going nowhere, so Gauche just enlarges it without waiting for it to be defeated, prompting Lupin Yellow to complain they hadn't actually killed it yet.
** ''Series/KishiryuSentaiRyusoulger'' is an interesting case. The Minosaurs are created by using humans as {{Living Batter|y}}ies and gathering enough human [[EmotionEater negative emotions]] and life energy would cause the them to instantly grow themselves. The host weakens as the Minosaur gets stronger, so the Minosaur going {{Kaiju}} size means you'd ''really'' better take it out in a hurry, because the host won't live much longer. This automatic growth is the only method, and if you ''do'' manage to take out a Minosaur before it happens, the Minosaur is truly dead.
*** The Druidon generals can also grow through different methods: Eras and Yabasword can grow at will, Tankjoh and the Gunjoji brothers have seismic energy inside them for enlarging, and Gachireus can fossilize himself to heal and grow.
*** In ''Series/PowerRangersDinoFury'', the Sporix grow ''naturally''. The longer they are not taken care of, the larger they will grow, until they become giant-sized. This was why Zayto's forces were still unable to defeat them on Earth, while the Morphing Masters had to devise Zords to assist the Rangers.
** ''Series/MashinSentaiKiramager'' takes the ''Battle Fever J'' and ''Go-Busters'' method UpToEleven: Any 20% of the overall negative energy the Jamenshi gathered are tranferred to Carantula's staff as part of the "Darkness Insurance Contract". Carantula would then summon the Jamen Beasts (giant monsters resembling {{Kaiju}} from the ''Franchise/UltraSeries'' or ''Franchise/{{Godzilla}}'' films) by using that energy to open the Invasion Gate. The Jamen Beasts have different base body types, but retain the themes of their Jamenshi counterparts (for example, both Rugby Jamen and Rugger Liagny are based on American football). As with ''Battle Fever J'' and ''Go-Busters'', sending a Jamen Beast while a Jamenshi is still active is very much an option.
*** Some Jamen Beasts don't have a corresponding Jamenshi counterpart and vice versa. Either because they don't have one (such as Faucet Hildon and Meteorite Jamen, who don't have a corresponding Jamenshi and Jamen Beast counterpart respectively), or its Jamenshi/Jamen Beast counterpart have a completely different theme (like in the case of Marshmallow Jamen with Hassha Liagny, or Nazokake Jamen with a trio of war-themed Jamen Beasts).
** ''Series/KikaiSentaiZenkaiger'' has ''both'' sides of the conflict pulling this off. For [[TheEmpire Tojitendo]], similar to ''Goggle Five'' and ''Fiveman'', a [[HumongousMecha Kudaitest]] would absorb a destroyed Wald's [[TransformationTrinket Tojiru Gear]] to transform into a [[{{Kaiju}} Great Wald]], only partially based on the original similar to ''Go-Busters'' or ''Kiramager''. For the Zenkaigers, apart from [[TheLeader Kaito]] and [[SixthRanger Zox]], their Kikainoid teammates ''are'' the mecha: naturally human-sized, they can enlarge themselves with another usage of their Geartlingers, and only in giant size can they become TransformingMecha and CombiningMecha.
* Oddly, the {{Trope Maker|s}} for ''Franchise/SuperSentai'' shows was actually Japanese ''[[Series/SpiderManJapan Spider-Man]]''. Yes, that one. When Toei made a {{Toku}} adaptation of ''Franchise/SpiderMan'', they couldn't think of a good spider-themed finishing move, so they had the villain make the monster grow and then Spider-Man would jump in his giant mecha Leopardon to defeat it. It was that kind of show. And yes, it ended up being a predecessor for Toei's own ''Sentai''.
* In the Tom Baker-era ''Series/DoctorWho'' serial "Robot", the robot absorbs energy from the Brigadier's RayGun and grows to giant size for the final battle with the Doctor.
* The BigBad in ''Series/MonsterWarriors'' is 1950s BMovie director Claus Von Steinhauer who creates giant versions of the monsters that featured in his movies and sends them out to attack Capital City. His CatchPhrase (which appeared in the opening credits) is "I make ze monsters big!".
[[/folder]]

** The first arc of ''Anime/DigimonSavers'' had all their [[MonsterOfTheWeek 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 [[SevenDeadlySins there was a reason for this]]. Ironically, with all the parallels ''Savers'' had with ''[[Series/PowerRangersSPD SPD]]''/''[[Series/TokusouSentaiDekaranger Dekaranger]]'', this was not one of them.
** The GrandFinale of ''Anime/DigimonXrosWars'' has Bagramon grow to gigantic size for the final battle. He also pulled out a OneWingedAngel form for this fight, but the growth was a separate thing.

** ''VideoGame/YoshisIsland'' has 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'' has similar for a giant adult Bowser made that way, again by Kamek's magic.

** Parodied (all the time) in ''Series/GekisouSentaiCarranger''. In order for the Gorotsuki (Bowzock's [[MonsterOfTheWeek Monsters of the Week]]) to grow, they must eat imo-youkan [[note]]a yellow cube-shaped food made from jellied sweet potatoes[[/note]]. Due to a unique effect the imo-youkan has on their biology, it causes them to glow red and blow steam from their nostrils before growing to massive size. Said food must be freshly hand-made from a certain store (Imocho). Factory-made and/or expired imo-youkan makes the Gorotsuki shrink (when this happens, they glow blue while blowing steam).

*** The ''Shinkenger'' crossover in ''Series/KamenRiderDecade'' averts this by virtue of StoryBreakerTeamUp, though: When the Ayakashi Chinomanako [[spoiler:stole Daiki's Diendriver and transformed into a corrupt version of Kamen Rider Diend]], his biology was somehow altered, meaning that it now had only one human-sized life. Really though, this was done mainly because Kamen Riders didn't start having their own HumongousMecha on a regular basis for another five seasons[[note]]However, there are Kamen Riders who face giant threats more often than others, though not OncePerEpisode. Take ''Film/KamenRiderJ'' and ''Series/KamenRiderHibiki''. The former makes himself grow whereas the latter, in spite of the size of his enemies, '''doesn't'''. ''Series/KamenRiderDenO'', ''Series/KamenRiderKiva'', and ''Series/KamenRiderDouble'' fight giant monsters semi-regularly, using their weapon-laden transforming CoolTrain, dragon castle, and bike that can attach to many other monster-busting vehicles, respectively. ''Series/KamenRiderOOO'' often doesn't ''need'' such things to deal with giant threats, taking out the first with a sword slash in finishing mode. It's too bad we ''didn't'' get to see Decade show the Rangers that you don't need giant robots to deal with giant beasties[[/note]].

*** Amusingly, in one ''Hurricanger'' instance, a particularly tiny monster is defeated and gets enlarged... to the same size as a regular human. He is promptly taken out a second time, and is ''then'' grown to the usual giant size.

*** ''Gokaiger'' also averts it in a couple of special instances: [[DiscOneFinalBoss Commandaner Warz Gill/Prince Vekar]] has a self-styled HumongousMecha, as does Insarn/Levira. [[TheRival Basco]] has Giant Battle Pseudo-Lifeforms, which he summoned by opening the compartment in Sally's chest whenever he wants to {{Troll}} the Gokaigers even more. And late in the series when [[GreaterScopeVillain Emperor Ackdos Gill/Emperor Mavro]] shows up, enlarging monsters became less common and finally stopped entirely after Insarn/Levira is killed off (though we do get some mecha battles later because at that point, the invasion fleet has arrived).

*** ''Series/PowerRangersDinoCharge'' replaced this with Sledge commanding a Vivix to fire the Magna Beam from his spaceship. The same beam can restore a monster to small size.

* The climax of ''Venom: The Enemy Within'' limited series has Demogoblin use the power or [[ArtifactOfPower an old enchanted necklace]] to grow to 20 feet, seemingly for the final battle with ComicBook/{{Venom}} and [[Characters/MarvelComicsMorbius Morbius]]. [[spoiler:However, he actually uses it to drown the hordes of evil otherwordly goblins in the river.]]

** ''Series/KishiryuSentaiRyusoulger'' is an interesting case. The Minosaurs are created by using humans as [[Living Batter|y]]ies and gathering enough human [[EmotionEater negative emotions]] and life energy would cause the them to instantly grow themselves.

This automatic growth is the only method, and if you ''do'' manage to take out a Minosaur before it happens, the Minosaur is truly dead.

** ''Series/ChikyuuSentaiFiveman'' zig-zags this. Similar to ''Goggle V'', a Gorlin (a giant robot purchased by the Zone for 100,000 Dolyens per unit) is summoned to absorb the Galactic Warriors. Unlike the Kongs, instead of being HumongousMecha copies, the Gorlin start out having a blank doll-like appearance (making it resemble the Michelin Man and/or the Stay Puft Marshmallow Man) before assuming the appearance of a Galactic Warrior upon absorption. They do this by way of shooting a beam that converts the Galactic Warriors into energy form, then absorbing the energy to replicate the appearance of the assimilated alien, using the genetic material of what was absorbed. That being said, Gorlins can't absorb a Galactic Warrior if they're killed off, as [[https://www.youtube.com/watch?v=GMs5GY_PeIs this embarrassing incident]] demonstrated. Moreso, those absorbed by Gorlins can actually free themselves if reminded who they are, as they apparently lose their free will after being absorbed.
*** First Captain Chevalier would later use a Black Gorlin, which cannot absorb Galactic Beasts but is more powerful than the regular version. It was more of a giant attack robot than a method of growing monsters, however.

** ''Series/NinjaSentaiKakuranger'' has the Yokai call for an enlargement jutsu. This results in them being struck with lightning (which is made from humanity's rage, hatred, and sorrow) from the Yoki Cloud to enlarge themselves.

*** Duke Org Rouki had his own Org Seeds, which are referred to as "Wolf Seeds". In ''Wild Force'', however, Zen-Aku doesn't use them on his Orgs, though.

*** Ultimate Org Senki, the FinalBoss of the series, wastes no time enlarging himself by using [=TsueTsue=]'s new staff after being formed from the three Highness Duke Orgs' remains. On the other hand, Master Org in his ultimate form can grow without it (though this mainly due to Jindrax and Toxica pulling a HeelFaceTurn earlier, which Yabaiba and [=TsueTsue=] never did).

*** There is a great deal of [[LampshadeHanging lampshading]] regarding monster growing in Ninja Storm, actually. On one occasion, the BigBad Lothor [[BreakingTheFourthWall looks directly at the screen]] and says, "What did you expect? He wasn't going to get smaller!" Another time, when Marah and Kapri first recruited Shimazu, Marah says, "What's the worst that could happen? They blow him up, we grow him big again, they blow him up again and we grow him big again and they blow him and we grow him and--" and Lothor cuts them off with, "I know [[StrictlyFormula the formula]]!" On another occasion, Lothor had just sent ''several'' monsters, and decides to make them ''all'' grow. Lothor tries, gets an error, and Zurgane reminds Lothor that he'd been too cheap to pay for the memory upgrade that would let multiple monsters grow at once. Lothor grumpily tells him to make just one grow.[[note]]This was a case of LeaningOnTheFourthWall, as Disney reduced the budget and said no more than one giant monster could be used in a battle.[[/note]]

** In ''Series/JukenSentaiGekiranger'' and ''Series/PowerRangersJungleFury'', enlarging is a ''martial arts technique.'' Monsters are able to do it at will. The Rangers, on the other hand, basically make mecha out of their [[KiManipulation Ki Attacks]].

** ''Series/ChikyuuSentaiFiveman'' zig-zags this. Similar to ''Goggle V'', a Gorlin (a giant robot purchased by the Zone for 100,000 Dolyens per unit) is summoned to absorb the Galactic Warriors. Unlike the Kongs, instead of being HumongousMecha copies, the Gorlin start out having a blank doll-like appearance (making it resemble the Michelin Man and/or the Stay Puft Marshmallow Man) before assuming the appearance of a Galactic Beast upon absorption.

Moreso, those absorbed by Gorlins can actually free themselves if reminded who they are, as they apparently lose their free will after being absorbed.

*** At some point in [=GP17=], Happa Banki dramatically shouts the usual growth command... and nothing happens. Turns out Go-On Gold had removed the monster's Bikkurium module during the battle!

** ''Series/ChikyuuSentaiFiveman'' zig-zags this. Similar to ''Goggle V'', a Gorlin (a giant robot purchased by the Zone for 100,000 Dolyens per unit) is summoned to absorb the Galactic Beasts.

** In ''Series/ChoujinSentaiJetman'', Dimensional Beasts are created when a Dimensional Bug possesses an inanimate object, but the bugs serve an extra purpose. When a Dimensional Beast is killed in combat, its Dimensional Bug is thrown from [[DefeatEqualsExplosion the monster's explosion]], and proceeds to grow ''itself,'' assuming the appearance of the dead Dimensional Beast while gaining its powers (though if the bug is destroyed alongside its Dimensional Beast, the monster can't be brought back). Alternately, Dimensional Bugs can work in that, when a Dimensional Beast is close to defeat, that it releases energy to rejuvenate and enlarge that Dimensional Beast (as observed with Road Jigen, whose Dimensional Bug gigantified him before the Jetmen could finish him off). The same rules also apply to the Bio-Dimensional Beasts and their Bio-Dimensional Bugs (which were differently shaped and colored compared to the normal Dimensional Bugs). Some Dimensional Beasts, such as Fighter Jigen and House Jigen, are already giants due to their Dimensional Bugs possessing large inanimate objects.

*** On one occasion, the BigBad Lothor looks directly at the screen and says "What did you expect? He wasn't going to get smaller!" Another time, when Marah and Kapri first recruited Shimazu, Marah says "What's the worst that could happen? They blow him up, we grow him big again, they blow him up again and we grow him big again and they blow him and we grow him and-" Lothor cuts them off with "I know [[StrictlyFormula the formula]]!"

* In one ''ComicBook/FantasticFour'' issue, [[ComicBook/MisterFantastic 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 [[ArtifactOfPower an old enchanted necklace]] to grow to 20 feet, seemingly for the final battle with ComicBook/{{Venom}} and ComicBook/{{Morbius}}. [[spoiler:However, he actually uses it to drown the hordes of evil otherwordly goblins in the river.]]

* In ''Film/ASimpleWish'', Mara Wilson's character wishes for her "fairy godmother" turn an antagonistic man into a rabbit. He ([[ItMakesSenseInContext yes, ''he'')]] ends up turning the man into [[EpicFail a giant rabbi.]] That's just ''the least'' of his screw-ups.

** As with ''Series/BattleFeverJ'', the Metaloids/Robotrons and Megazords/Gigadrones aren't the same critters in ''Series/TokumeiSentaiGoBusters'' and ''Series/PowerRangersBeastMorphers''. As such, (also just as in ''Battle Fever J'') while the Megazord/Gigadrone ''usually'' arrives just after the Metaloid/Robotron is killed off, there are nearly as many times when the team must split up as some fight the Metaloid/Robotron on the ground and the rest fight the Megazord/Gigadrone in their own HumongousMecha, or the Megazord/Gigadrone must be fought first while the Metaloid/Robotron carries out the evil plot du jour in hiding. Monsters in this series are created from Earth objects, and on one occasion, a robot based on a monster is ''turned into a monster itself,'' and soon ''a new robot based on it arrives''. At one point you've got a robot ''within'' a monster ''within'' a robot. [[MindScrew Hurts your head, doesn't it?]] [[spoiler: This "Megazord Zeta" in turn is possessed by [[BigBad Messiah]] and takes on yet another form!]].

** ''Series/KishiryuSentaiRyusoulger'' is an interesting case. The Minosaurs are created by using humans as LivingBatteries and gathering enough human [[EmotionEater negative emotions]] and life energy would cause the them to instantly grow themselves.

This automatic growth is the only method, and if you ''do'' manage to take out a Minosaur before it happens, the Minosaur is truly dead.

* ComicBook/{{Mysterio}} from one of the ''Franchise/SpiderMan'' games does this.

* For ''VideoGame/CapcomVs'' examples, ComicBook/{{Apocalypse}} in ''VideoGame/XMenVsStreetFighter''.

* In the ''VideoGame/{{Touhou}}'' fighter ''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[[/note]] so it only makes sense that she can do this.
** in 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 [[FantasyKitchenSink 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"

* Averted in ''Film/MightyMorphinPowerRangersTheMovie''! The two Ectomorphicon Titans are already giant, and the only "growing" is when Ivan Ooze merges with one of them. (Maligore does make himself grow in the second.)

** ''Series/NinjaSentaiKakuranger'' has the Yokai call for a enlargement Jutsu. This results in them being struck with lightning (which is made from humanity's rage, hatred, and sorrow) from the Yokai Cloud to enlarge themselves.

** In ''Series/DenjiSentaiMegaranger'', [[BigBad Dr. Hinelar]] ran an experiment on [[TeamPet Bibidebi]] in Episode 3, which gave him the ability to infect Nezire Beasts (and later, Psycho Nezilars) with an enlargement virus. Whenever a Nezire has been defeated by the Megarangers, he beams down, cries out "Gigant Virus Injection!", and bites the Nezire Beast/Psycho Nezilar, infecting their DNA (with little, Bibidebi-shaped molecules) and causing them to enlarge. In one instance, [[TheHero Mega Red]] completely obliterated [[MonsterOfTheWeek Lion Nezilar]], but Bibidebi improvised another growth process by sucking the flames and smoke remaining from the destroyed monster's explosion into his mouth, then blowing it out as a fine mist to rematerialize Lion Nezilar at titanic size.
