After generations of {{Kaiju}} movies including Franchise/{{Godzilla}}, Franchise/{{Gamera}} and countless imitators, viewers seem conditioned to accept that any giant monster or robot is completely [[ImmuneToBullets immune to conventional weaponry]]. This can be a problem for filmmakers, either making the military in their films look stupid for [[RedshirtArmy even being there]] or destroying the audience's SuspensionOfDisbelief when FiveRoundsRapid ''actually works.'' Not much can be done about this.

It would seem that audiences usually like to see a [[PlayingTennisWithTheBoss more]] [[YourMindMakesItReal creative]] [[CosmicKeystone method]] for destroying the monster than MoreDakka.

There are a few methods for overcoming this, including DepletedPhlebotinumShells and (inexplicably) attaching the very same weapons to another giant robot or monster. On the other hand, simply laying out poisoned bait for these critters and letting their appetites do them in will never, ever, ''ever'' occur to anyone[[note]]Except in Film/GameraVsGyaos[[/note]].

This trope is a staple of the SuperRobotGenre and RealRobotGenre, since it justifies the existence of the HumongousMecha. Since a {{Robeast}} can not be defeated through conventional weaponry, it must be fought with another giant enemy.

Contrast the SquareCubeLaw, which suggests larger things should actually be ''weaker''. However, assuming that the Square Cube Law is still in effect, and they still don't collapse and die, then this trope is justified because the creature [[RequiredSecondaryPowers explicitly needs to be superstrong and massively durable]] simply to withstand their own weight and be able to move with any reasonable efficiency (indeed, beyond a certain size the body would have to incorporate substances stronger and more durable than anything that exists in real animals). For example, a human scaled up by merely twice his own height would weigh eight times more. The strength necessary to move his own body weight would make him incredibly overpowered versus normal-sized opponents.



[[folder: Anime and Manga ]]
* ''Anime/MazingerZ'' and its sequels (''Anime/GreatMazinger'' and ''Anime/UFORoboGrendizer'') played this trope straight. Combat jets, tanks, missiles... could not even scratch the armor of a {{Robeast}}, and it could only be defeated by a similarly giant weapon. It is subverted with the {{FemBot}}s, though, since Aphrodite A, Diana A and Venus A could be easily defeated, and Aphrodite A could be briefly deterred by an army of {{Mooks}} using conventional weapons.
** Subverted when Kouji destroyed one of the [[{{Robeast}} Mechanical Monsters]] of Archduke Gorgon using landmines -even though it was supposed to be stronger than [[BigBad Dr. Hell]]'s Mechanical Monsters!-.
* ''[[Anime/{{Gigantor}} Tetsujin28-Go]]'', the first HumongousMecha played this trope completely straight. It was intended to be Japan's ultimate weapon during World War II. Since that war was over before the robot was finished, Tetsujin is used to fight mostly criminals and terrorists.
* ''Manga/GetterRobo'' (that battled giant cybernetic DINOSAURS), ''Anime/{{Raideen}}'', the ''Anime/RobotRomanceTrilogy'' -''Anime/CombattlerV'', ''Anime/VoltesV'' (it was supported by the army, but conventional weapons were never strong enough to battle Boazanian's Slave Beasts), ''Anime/{{Daimos}}''-, ''Anime/{{Zambot3}}'', ''Anime/{{Daitarn3}}''... conventional weapons can not touch any of them.
* In ''Anime/TengenToppaGurrenLagann'', the HumongousMecha are shown to be vulnerable to concentrated small-arms fire (something that [[BadassNormal Yoko]] uses to her advantage on a number of occasions). This hasn't stopped some viewers from asking, "Why are they shooting at the robots when they know it won't do any good?" later on.
* ''Anime/NeonGenesisEvangelion'': They try bullets, missiles, and clean nukes on the angels; but [[spoiler:[[AssimilationPlot part of]]]] the reason the Evas exist is that the Angels are protected by a force field (they call it an AT field) that only the Evas can cancel out with their own AT fields. Though there are cases where science fiction-based weapons '''do''' defeat them.
* The trope is averted in ''Anime/{{Macross}}'' for both the Zentraedi and their battle pods. While ''Anime/SuperDimensionFortressMacross'' shows that Zentradi (at least those of Bretai's type) are powerful enough to dismember GiantMecha with their bare hands, human weaponry or Zentradi weapons wielded by humans can take them down in an instant.
* ''Manga/GiantRobo'' takes place in a world where 'Experts' have various superpowers and can duke it out with each other, to the detriment of the landscape. But with a title like ''that'', guess where the ''real'' force is. The show mostly plays it straight - Giant ''does'' equal Invincible, unless you're [[DangerousForbiddenTechnique prepared to die soon afterwards]].
* ''Franchise/{{Gundam}}'' is all over the place with this trope. The Universal Century series have anti-Mobile Suit infantry tactics being reasonably effective while armies in the Alternate Universes generally don't field infantry against Mobile Suits at all. However one of the series' major conceits is that Mobile Suits can effortlessly take down battleships and Mobile Armors hundreds of times larger than themselves.
* ''Anime/ScienceNinjaTeamGatchaman'' subverts the trope. You only needed the Gatchaman team -a FiveManBand of teenagers with a CoolAirship-to take on a HumongousMecha and destroy it.
* Played with in ''Manga/OnePiece''. While more powerful characters tend to be bigger, giants are easily taken down by the more powerful characters. One subversion is Oars Jr, who, though he could take cannonballs with ease and smash through smaller giants (wrap your brain around that), all it meant for the truly powerful characters was that he presented a bigger target.
* Zigzagged in ''Manga/FullmetalAlchemist''. Envy's [[OneWingedAngel gigantic true form]] is the biggest creature in the series, and focuses more on brute strength than speed. This makes him more than a match for Ed, Ling, and on other characters who are completely unprepared for his transformation. Later when he uses this against [[PlayingWithFire Roy Mustang]], Roy simply flash-fries him over and over, pointing out that all Envy did was give him a bigger target. It also didn't help that they were fighting in an enclosed space that took away any maneuverability Envy might've had elsewhere.
* Subverted in ''Manga/AttackOnTitan''. Titans are actually [[MadeOfPlasticine very fragile]], and not only do conventional weapons damage them without issue, they're also prone to injuring themselves by accident. The problem is that they FeelNoPain (unless you stab them in the eyes) and have an incredibly powerful HealingFactor, with only [[AttackItsWeakPoint one possible way]] to put them down for good. It makes killing one a very difficult and dangerous proposition.

[[folder: Comic Books ]]
* ''ComicBook/XMen'': Sentinels aren't invincible (yet), but they are built exceptionally tough because their intended targets can [[ComicBook/{{Cyclops}} shatter you with a glance]], [[ComicBook/{{Wolverine}} cut anything]], [[ComicBook/{{Storm}} throw lightning]], [[Comicbook/{{Magneto}} bend steel with a thought]] or just [[ComicBook/JeanGrey treat matter like tinker-toys]]. As a consequence, we don't often (if ever) see conventional arms used against them.
* Comicbook/TheUltimates takes great joy in [[AvertedTrope averting]] this as part of its more "realistic" take on superheroes. Giant-Man (non-combatant Hank Pym) is nothing more than an oversized, unskilled, still-entirely-squishy human who is ''repeatedly'' curb-stomped by his [[BadassNormal opponents]] or even just [[EpicFail inconveniently placed obstacles]]. The ''entire concept'' is jettisoned as a useless gimmick for a superhero, and instead gets used for [[MundaneUtility cleanup and construction.]]
* ComicBook/{{Supergirl}} has occasionally faced up to giant monsters and robots that were tough enough to resist her attacks.
** In ''Comicbook/{{Batgirl 2009}}'' she tells a friend about it.
--->'''Comicbook/{{Batgirl}}:''' I thought only the green stuff could hurt your... is "kind" offensive at all?\\
'''Supergirl:''' Depends on which one of us you ask. And it isn't just Kryptonite. There's all kinds of little hiccups. Magic. Electricity. Sometimes robots, if they're big enough.
** Played straight in ''ComicBook/{{Bizarrogirl}}''. Supergirl usually is more than capable of dealing with monsters, but the moonsized [[PlanetEater Godship]] is too tough to be punched out and strong enough to smash her away. It easily withstands the assault of an army of SelfDemonstrating/{{Bizarro}} clones and finally the heroes have to resort to power up Bizarrogirl's petrifying vision to merely freeze it.
* In an early story Franchise/{{Superman}} had some difficulty when he once fought an alien giant robot. It was as strong and invulnerable as he was, so whenever Supes and the alien robot traded punches neither was hurt. The robot then used its superior to size to grab Superman and stuff him inside a compartment within. Superman eventually escapes and defeats the robot by dismantling it at the joints.

[[folder: ''Neon Genesis Evangelion'' Fan Works]]
Seeing how this trope is crucial to the series, it's only natural that it shows up in fan fiction.

* ''Fanfic/ACrownOfStars'': Asuka Langley Sohryu pilots a [[TransformingMecha Star Strider]], a flying robot just as tall as the Statue of Liberty. When she fights tanks and foot troops... You can guess the result.
* ''Fanfic/AdviceAndTrust'': Regular army forces do nothing against Evas or Angels. During the battle against Leliel land tropes surround the Angel to let Nerv apply pressure. One of the BridgeBunnies asks if they are useful and Misato notes disdainfully that Leliel is intimidated by their presence not at all.
* ''Fanfic/TheChildOfLove'': After the Angel War Shinji and Asuka are cajoled into taking part in peace-keeping missions. They donít want to kill anyone but Misato assures them the only thing they have to do is show up and scare them because everyone knows giant robots are invincible.
* ''Fanfic/ChildrenOfAnElderGod'': Since the enemies in this story are {{Eldritch Abomination}}s of the Franchise/CthulhuMythos, conventional weaponry, tanks, fighter jets, missiles, nukes... are predictably useless, and they can only be found using bio-mechanical giant super robots which are, in fact, cloned {{Eldritch Abomination}}s.
* ''Fanfic/DoingItRightThisTime'': In the first story draft, an Admiral complains about using giant robots to fight monsters. Asuka quickly points out a HumongousMecha is the only thing has worked so far with {{Robeast}}s and {{Kaiju}}s.
-->''"There's got to be a better way of doing this," he grumbled to himself, in the mistaken belief that Asuka's English was anything but impeccable. "I mean, giant robots for heaven's sake!"''\\
''"Technically the Evangelions are cyborgs. And you could well be right, but so far we've killed three more Angels than any other weapon of man's devising."''\\
''The man scowled, but conceded the point.''
* ''[[Fanfic/GodsAngelsAndKings Hail To The King]]'': Subverted. Initially it is played straight: when the [[HumongousMecha Evangelions]], the {{Kaiju}} and the [[EldritchAbomination Angels]] come to blows the army of the Evangelion universe could stay in home for all the good its presence will do. However, the Godzilla universe army has decades of experience dealing with giant, superpowerful and nearly invulnerable monsters, and they are at least capable to provide cover fire, distract or slightly weaken the enemy.
* ''Fanfic/{{HERZ}}'': The narration blatantly points out that HERZ is still invincible because... well... giant robots.
-->''Despite of the loss of much of NERV's old autonomy, HERZ was still greatly feared. Exclusive control of Unit 01 and the remaining Eva-05 series meant that she could defeat any conventional armed force on the field.''
* ''Fanfic/LastChildOfKrypton'': Subverted. Yes, the regular army is useless against Angels or Evangelions... but when (human-sized) Shinji [[spoiler:a. k. a. Franchise/{{Superman}}]] comes along, being giant only means that you are a giant ''target''.
* ''Fanfic/OnceMoreWithFeeling'': After Shinji got fed up with an admiral dissing the Evangelions, Shinji narrates his first engagement and points out that the HumongousMecha is the only thing can damage an Angel because conventional weaponry is useless.
-->''ďWell Sir, I have, so has the First Child and Iím sure very shortly, so too will have the Second [...] In my first engagement, I went up against an Angel that chewed through a Tank Battalion in four minutes flat, destroyed three dozen aircraft and took more firepower then this entire battle group could dish out, right up to the use of Strategic scale N2 weapons. The UN and JSSDF threw everything they had at it and barely slowed it down at the cost of over a thousand lives and half a billion US dollars. [...] With the greatest of respect, Sir, [...] the twin of that toy you are transporting took out that Angel in sixty three seconds, with no civilian casualties, no military casualties and minimal collateral damage to the city it was fighting in.Ē
* ''Fanfic/TheOneILoveIs'': Although he hates fighting, Shinji gets forced to pilot a giant robot because there is nothing else can damage the [[{{Robeast}} Angels]], and the is the only one can pilot Unit 01.
* ''Fanfic/ScarTissue'': Ritsuko notes in one scene that they can not beat one of their giant robots with anything other than another giant robot.
* ''Fanfic/TheSecondTry'': Conventional weaponry does nothing to Evas or Angels. When the army assaulted the Geofront Asuka's HumongousMecha destroyed foot troops, entire tank battallions, [=VTOLs=] with insulting easiness whereas Shinji's giant robot protected her power cord with an impregnable barrier that no projectile could pierce through. It went on until the army gave up and deployed Seele's HumongousMecha. Shortly before Asuka had said that the soldiers were not the real problem (since their enemy were the MP-Evas).
* ''Fanfic/SOE2LoneHeirOfKrypton'': Subverted. The regular army is useless when it is time to fight [[{{Robeast}} Angels]] or even [[HumongousMecha Evas]]. No weapon of theirs can damage them. However, Asuka -who in this setting is ''Comicbook/{{Supergirl}}''- can fight them more effectively with her bare hands than with a giant robot despite of being an average-sized human. In fact she manages [[spoiler:taking Armisael down and surviving, something no Eva could do]].
* ''Fanfic/ThousandShinji'': Subverted. The army is mostly useless against the Angels, but some troops were capable to assist Shinji by providing cover fire to distract Ramiel.
* ''Fanfic/NeonGenesisEvangelionGenocide'': As soon as new humongous [[EldritchAbomination Angels]] show up, itís made clear that the army keeps being helpless against them, and the Evas must be deployed again.

[[folder: Fan Works ]]
* ''FanFic/BattleFantasiaProject'': Justified in the remake. When the Nightmare Factory deploys a {{Kaiju}}, it's quickly pointed out that [[ClapYourHandsIfYouBelieve magic tends to make beliefs real or more probable]], and as it happened in Japan the Kaijuu was effectively invincible unless fought by a PhysicalGod, someone with divine-inspired powers, or something equally large (it was taken down by the [[WesternAnimation/MegasXLR Megas]]).
* ''Fanfic/MesozoicEffect'': Averted. Larger dinosaur breeds are typically used as long-range support units specifically because they ''aren't'' invulnerable, and their large size just makes them sitting ducks for the high power kinetic weapons of the Franchise/MassEffect universe. When they do fight up close, they wear large suits of PoweredArmor that generally turn them into MiniMecha, complete with arsenals of weapons and gadgets. Even with these upgrades, they still aren't as durable as tanks and typically have to rely on their superior mobility to stay alive.
* ''Fanfic/{{Wonderful}}'': When a house-sized tank attacks main character's super-hero team, Taylor and her teammates manage to destroy it... but they needed to use giant weapons to do so.
* ''Fanfic/TheBridge'' plays it completely straight on the Terran side, where only high end mecha or extremely rare superweapons have any effect on kaiju and it usually took one of the more heroic kaiju to save the day. On the Equestrian side, it flip flops. Bladed weaponry are obviously useless and magic blasts from an extremely powerful unicorn like Starlight Glimmer might just get a kaiju's attention; but WordOfGod and demonstration show more powerful artifacts like the Crystal heart and potent alicorn magic can do some damage.
* [[DiscussedTrope Discussed]] in ''FanFic/TheDilgarWar'', where a few characters talk about the latest ''Franchise/{{Godzilla}}'' movie and one of them mentions an easy way to deal with it: [[OrbitalBombardment a single railgun shot from an orbiting starship]].

[[folder: Film ]]
* This could be the reason dinosaurs in the first two ''Franchise/JurassicPark'' movies appear to be bullet-proof. (Though granted, we puny humans rarely get a chance to even try shooting.) They don't seem to be ''completely'' invincible. After all, the hunters in ''[[Film/TheLostWorldJurassicPark the second film]]'' are able to catch them in large numbers, and it is implied that the head hunter's elephant gun would have worked on a TyrannosaurusRex had the [[DesignatedHero environmental terrorist]] not stolen his ammo. Also, there's the instant death coral poison gun that got [[TooDumbToLive tangled in some cargo netting.]]
** In the [[Film/JurassicWorld fourth movie]] this is zigzagged. The pterosaurs are each taken down by one shot, but it can be assumed it's because they're not really that big[[note]]and, being {{Giant Flyer}}s, they're also more lightweight and built for speed rather than strength, so this may also be a case of FragileSpeedster and/or GlassCannon[[/note]]. Meanwhile the ''[[BigBad Indominus rex]]'' barely seems to notice when she's being shot at and shrugs off a barrage of machine gun and rifle fire through the movie. She does improvise some quick evasive maneuvers when subjected to fire from a helicopter-mounted minigun, though.
* ''Film/TransformersFilmSeries'':
** One of the (many) common complaints against Creator/MichaelBay's [[Film/TransformersRevengeOfTheFallen second film]] is the presence of human soldiers with rifles during the battle. It seems that they're only there because Bay wants to see their bodies pinwheel through the air from explosions. Never mind that we see [[BigBad Megatron]] himself driven back by concentrated fire from the fleshlings.
** By [[Film/TransformersDarkOfTheMoon the third film]], they have learned to take down Cybertronians with ''assault rifles''. Granted, those rifles are firing armor-piercing rounds, but they are shown to be training in tactics specifically designed against large robotic opponents, such as dropping from above and [[EyeScream going for the eyes]]. They still drop like flies, especially when the Decepticons bring out the disintegrator guns, but are able to take down a number of enemy 'bots including [[spoiler:Shockwave]].
*** All of this is justified though. The first movie revealed that humans discovered just what type of man-made weapon capable of injuring a Cybertronian, and actively made that the standard issue ammo for all soldiers in the following films.
* In ''Film/{{Cloverfield}}'', WordOfGod tells us that the traditionally unstoppable monster [[spoiler:was killed by the "Hammerdown Protocol"]], although one wonders what effect it would have on it's 'Film/{{TheCloverfieldParadox}} mother.''
* Every ''Franchise/{{Godzilla}}'' movie ever. (In the [[Film/{{Gojira}} original]], the "Oxygen Destroyer" kills Godzilla. Still, it's not a conventional weapon, but a 'superscience' type. The [=SuperX=] in much later films has some effect.)
** ''Film/GodzillaVsDestoroyah'' subverts this. Turns out that too much radiation ''can'' kill Godzilla. The downside is that it'll cause him to go into a meltdown and destroy the world. Granted, nuking Godzilla is a bad idea in the first place, since it'll make him larger and more powerful before it has any fatal effects on him.
** Subverted in ''[[Film/GodzillaMothraKingGhidorahGiantMonstersAllOutAttack GMK]]''. Godzilla is defeated after [[spoiler:swallowing a submarine that uses high-powered torpedoes to drill a hole through his chest allowing said submarine to escape, and causing Godzilla to explode by his thermonuclear breath tearing him apart from the inside out via said hole]]. It doesn't kill him, per se, but at least he's been [[spoiler:reduced to a disembodied heart]].
** In ''Film/GodzillaFinalWars'', fans had every reason to expect invincible kaiju. Ryuhei Kitamura attempted to overcome this trope with superhuman mutants and flying battlecruisers with lasers.
** Part of the reason for the hate for the first American ''Film/{{Godzilla 1998}}'' movie is that this is averted. While Zilla is pretty much immune to small arms fire, big guns and bombs are able to hurt him, and late in the movie he is injured and eventually killed by conventional weaponry.
** Brought back full-force in ''Film/{{Godzilla 2014}}''. The [=MUTOs=] and Godzilla [[ImmuneToBullets shrug off all bullets,]] tank rounds, and sea-to-ground missiles, though rifles successfully distract the [=MUTOs=] more than once. It is confirmed in the movie that Godzilla can survive point-blank nuclear explosions in the kiloton range, though they have no idea what megaton-level explosions will do. However, the nuclear initiation that the movie shows targeting Godzilla is known to us as the Castle Bravo test, which is famous not only for being one of the first multimegaton tests, but for unfortunately exceeding expectations- the expected 4-8 megaton explosion was roughly 15 megatons. No nuke in the current arsenal is capable of that [[note]][[ArtisticLicenseHistory This particular variation appears to be based on only fixating on what can be done with today's "cool DARPA technology" and not considering other factors; while the know-how exists, the political will doesn't]][[/note]].
* Averted with ''Film/{{Rodan}}''. Both monsters die in a volcano while the JSDF bombs them with an air strike.
* Subverted in the 90's ''Franchise/{{Gamera}}'' trilogy. Gamera is easily shot down by missiles. They don't kill him, but they certainly do their fair-share of damage to the giant turtle. He does grow more durable and powerful in later movies to where anti-aircraft missiles can slow him down somewhat, but don't actually hurt him.
* Averted in ''Film/KingKong1933''. Kong is gradually shot down by biplanes (Helicopter gunships in the [[Film/KingKong1976 1976 remake]]), and slowly dies from shot after shot.
* Played straight in ''Film/KongSkullIsland'', where King Kong takes out a full squadron of helicopter gunships, though he does bleed a bit and his palm shows scars from their rotors. The ''small'' Skullcrawler shrugs off several small arms and even a flamethrower and is only killed when a gas vent is set on fire under it. [[spoiler:The big one survives even Kong cutting its throat open with a ship's propeller and it takes him ripping its guts out through its mouth to kill it.]]
* Downplayed in ''Film/PacificRim'': the {{Kaiju}} aren't ''entirely'' immune to conventional tanks and bombers, but are so resistant to them it takes days of constant attacks just to kill one, all while the things tear the hell out of cities. The collective world community agreed to [[NuclearWeaponsTaboo stop using nuclear weapons on the Kaiju]], because even though they work, doing it over and over again was far more destructive to the planet and humanity in the short run. The point of [[HumongousMecha Jaegers]] isn't just to kill the things, but to kill them ''quickly''; preferably before they even reach the coast. The Kaiju eventually built a nuke-proof variant anyway.
* Justified in ''Film/IndependenceDayResurgence'' by having the giant Queen Alien have it's own individual forcefield.
* In ''Film/CaptainAmericaCivilWar'', [[spoiler:[[Film/AntMan Giant-Man]] is seemingly impervious to both Iron Man and War Machine's artillery, though to be fair, they were not trying to use lethal shots. It takes a combination of "[[Film/TheEmpireStrikesBack really old movie]]" tactics and a wrecking ball-like slam from a superdense Vision to knock him down.]]
* A very literal example in ''Film/BigAssSpider'', with the eponymous menace, upon reaching Kaiju size, being immune to gunfire and even [[spoiler: surviving a direct missile strike.]] Meanwhile, [[spoiler: its newly-hatched (small) offspring prove to be susceptible to being shot.]]

[[folder: Literature ]]
* Averted in ''Literature/TheScar'', where the gargantuan avanc slowly succumbs to infection after it gets injured by the grindylow. We don't actually see what weapons they'd used to damage it, but the lakeful of pus it emits while ailing is a definite sign that it's the infection, not the wounds themselves, that proves fatal.
* Averted in ''Shadow's Fall'', where the "unpowered" retired super hero Lester Gold takes on a T-Rex by tricking it into swallowing a grenade, leading to "your head asplode". Played straight with the Great Wurm, Cromm Cruach.
* This is certainly the characters' initial reaction to the skyscraper-sized vordbulks in ''First Lord's Fury'', the final book of Jim Butcher's ''Literature/CodexAlera'', but then a few bright sparks work out [[AttackItsWeakPoint their weak points]]...
* Averted in Taylor Anderson's ''Literature/{{Destroyermen}}'' series, where the alternate Earth features many extant dinosaurs and other giant creatures (such as Mountain Fish, which are enormous whale-like creatures that eat ships for breakfast). Enough bullets, especially firing at eyes or opened mouths will bring down any creature. Hell, several times, attempts to ''scare off'' a Mountain Fish resulted in their accidental death. Turns out it can't handle a depth charge very well. In fact, one of the main characters, a BoisterousBruiser named Dennis Silva, turns a Japanese anti-aircraft gun into a {{BFG}} musket he calls the Doom Whomper, designed specifically to hunt the allosaur-like superlizards but doubling as a sniper rifle in a pinch.
* Zigzagged in the ''Literature/NemesisSaga''. The natural black armor on the kaiju protects them from anything the military throws at them, including a M.O.A.B.. However, their armor is not completely impenetrable and if removed, their soft, pale skin underneath is susceptible to conventional military fire.
* This is more or less true of all the creatures in ''Literature/KaijuRisingAgeOfMonsters'' with only the occasional HumongousMecha being able to scratch them. Given this is a horror anthology, even that isn't necessarily going to work all the time.
* ''Literature/TheWarAgainstTheChtorr''. The Enterprise fish can mass over a million tons and requires a tactical nuclear weapon to destroy. Justified when it's revealed the 'fish' is actually a large number of symbiotic creatures joined together.

[[folder: Live Action TV ]]
* The ''Franchise/UltraSeries'' sees this a lot. The defense teams always attacks the MonsterOfTheWeek with a huge variety of weapons and technology, from ray guns and high-tech jet fighters, but typically only Ultraman can actually defeat the monster. However, it has been averted on a few occasions, where the team is able to kill or seriously injure a {{kaiju}} with their weaponry. It takes circumstances, (often) special one-of-a-kind weaponry, and ''a lot'' of hard work, but the human teams ''are'' capable of protecting Earth on their own. Not to mention that it's even better when the teams and Ultraman cooperate.
* A lot of Japanese {{Toku}}satsu shows play this fairly straight, pretty much following the examples of ''Franchise/{{Godzilla}}'' and ''Series/{{Ultraman}}''. In fact, anytime a human-scale character offs a building-sized one, it's likely to be a [[SugarWiki/MomentOfAwesome CMOA]] of some sort.
* In ''Franchise/PowerRangers,'' if you don't have a HumongousMecha, you should basically run. It's ''exceedingly'' rare that the most godlike weapons used at human scale can scratch the monster after MakeMyMonsterGrow ensues. And yes, it ''is'' freaking awesome and remembered forever when a Ranger manages to avert this. (As you can imagine, of the three times it happens, once it was [[LawOfChromaticSuperiority a Red Ranger]], once it was a SixthRanger, and once it was [[MemeticBadass Tommy]].)
* Played straight in ''Series/TerraNova''. Even dinosaurs that are only slightly larger than people shrug off small arms like they're nothing. Even the mounted wave cannons on the walls of the compound only repel a ten foot tall dinosaur.

[[folder: Newspaper Comics ]]
* Parodied by one of the final unpublished strips of ''ComicStrip/TheFarSide'', available in ''Last Chapter And Worse''. A man is interviewed after taking down a Godzilla-like monster with his shotgun. "Well, I seen all the commotion, with that there monster destroyin' half the city and whatnot, and I says to myself 'Hell! Why don't someone just shoot the varmint?'"
** Also averted in one depicting a massive, slain mastodon, [[AttackItsWeakPoint with a miniscule arrow in its buttock]].
-->'''Caveman:''' Maybe we should write that spot down.
** As a GeniusBonus, this is one of the theories about what spurred early man to invent writing.

[[folder: Roleplay ]]
* ''Roleplay/DestroyTheGodmodder'' follows this sometimes, and other times throws this out the window. It all depends on if said giant beastie is the godmodder's or something one of the players summoned.

[[folder: Tabletop Games ]]
* Averted in ''TabletopGame/{{GURPS}}''. Whenever a single giant monster appears, the players tend to take it out with a single shot to the eye. Creatures that big tend to have eyes that are easy to hit, and damage multiplier tends to make even a T-Rex go down in one or two hits.
* In ''TabletopGame/DungeonsAndDragons'', bigger monsters tend to be tougher, but not necessarily ''because'' they're bigger. Bigger monsters are also bigger targets.[[note]]-1 AC for being one size category above Medium (e.g. most humanoids), and doubling with each subsequent category.[[/note]]
** The Titanic template[[note]]templates modify the 'base creature' they are applied to -- Titanic is designed to make a medium-sized or smaller animal into a gargantuan-sized animal[[/note]] is a downplayed version of this trope -- it is entirely possible to kill Titanic creatures using ordinary weapons, but they have a lot more hit points than the base animal, and a lot of natural armor (meaning that, due to what AC and Touch AC represents, they are a lot easier to hit, but roughly as easy to somewhat harder to hit well enough to actually do any damage).
* Played mostly straight in ''TabletopGame/{{Warhammer 40000}}''. Big monstrous creatures like [[BeastOfBattle Squiggoths]] or the larger [[HordeOfAlienLocusts Tyranid]] bio-forms (to say nothing of [[HumongousMecha Titans]]) have such a high Toughness or Armor Value that most standard infantry weapons are incapable of dealing damage to them. That said, even basic infantry squads can purchase a specialist weapon like a missile launcher or meltagun, so such big, nasty, expensive units ignore infantry at their peril. Furthermore, certain units fire special poisoned rounds that are effective against any creature regardless of Toughness, while sniper rifles have a similar rule representing how their wielders are able to target weak points.
* Averted in ''TabletopGame/BattleTech''. [[HumongousMecha BattleMechs]] may be the more-or-less official "kings of the battlefield" and heavier designs are tougher than lighter ones, but they're still only glorified ''tanks'' on legs and remain vulnerable to lucky hits and cumulative damage from even 31st century infantry weapons assuming the infantry can live long enough to get into range and exchange fire with them for a while. (Urban combat in particular can become a legitimate nightmare for them.)
** ''TabletopGame/BattleTech'' is an interesting reversal, actually - instead of making the mechs tougher than conventional tanks, they made the tanks weaker. For one thing, tanks are smaller targets, but no more difficult to hit than a 'mech. For another, although the mechs are depicted as having more exposed or lightly armored parts, the odds of a critical hit are higher versus a tank than a mech.
* The ''Mecha vs Kaiju'' FATE rules offer several different forms of this. The simplest is to simply assume that the giant monsters and giant mechs are completely impervious to anything smaller. A more complicated version has a system of six scales ranging from "Human" to "Astronomical" (with even Franchise/{{Godzilla}} not being "Astronomical" at his biggest), and every difference in scale lets the larger party replace one of the FUDGE dice with a standard D6, meaning that a weak Towering kaiju is effectively rolling an average of 7 higher than an infantryman, and 3.5 higher than a tank (switching from dice that range from -1 to +1 to dice that start at +1 and get higher is very strong in FATE). It does try and balance this out a tiny bit by preventing any kaiju without the Bug Stomp stunt from directly engaging a specific puny mortal.
* ''TabletopGame/TheDresdenFiles'' RPG has a power available called "Hulking Size," which, while it doesn't make the creature invincible, does give it two extra stress boxes, meaning it can take more damage before it's wounded -- the normal max is 4 without outright [[MadeOfIron toughness powers]]. Given this is for creatures the size of a small house, the main downside of the power is it gives any enemy a +1 to hit it when size is a factor.
* Ultimately subverted in ''TabletopGame/{{Champions}}'': while bigger PCs and NPCs get harder and harder to take down (especially when PCs take "[[NighInvulnerability Nigh Invulnerable]]") they ''will'' fall eventually. It's more about players not having to spend sessions trying to grind down one giant and to keep a sense of danger when a giant PC fights as when they are fighting a kaiju, they're in the same boat as the lizard.

* ''VideoGame/MechAssault'' and ''VideoGame/TheIncredibleHulkUltimateDestruction'' both have harmless infantry enemies. The former is excused in that they're members of a fanatical cult who aren't afraid to die. The latter are member of the US army, but they'll try to avoid the Hulk...for the most part. If he can get close enough, they'll try rifle-butting him, which works about as well as you'd expect.
** ''VideoGame/MechAssault'' and the ''VideoGame/{{Mechwarrior}}'' series it spun off from actually zigzag quite a bit with this trope. FiveRoundsRapid can't do much to even a scout Mech barring ''extremely'' extended attrition but a single properly placed satchel charge can bring even a hulking Assault-class machine down and clan [[PoweredArmor Elementals]] (or IS Battle Armor) can take down ''several'' Mechs alone if the wearer is skillful.
** The effective variant tends to rely more on [[AttackItsWeakPoint damaging a vulnerable spot]] via HumongousMecha {{Kneecapping}}. Most of the games where non PoweredArmor-wearing troops fire infantry-scale weapons at 'Mechs don't include this tactic, and examples such as ''Mechwarrior 3'' messily demonstrate why an average human shouldn't be anywhere ''remotely'' near a 'Mech.
* The ''VideoGame/{{Earth Defense Force|2017}}'' series gleefully averts and inverts this. You play as a wimpy looking guy in a baggy jumpsuit who is tasked with killing swarms of giant bugs, towering mechs, kaiju, flying saucers, and walking fortresses. On foot. With conventional weaponry like assault rifles and shotguns. And it works!
* The ''VideoGame/MonsterHunter'' series averts this trope in its later monster hunts.
* In the ''VideoGame/DragonBallZBudokaiTenkaichi'' series, giant characters will not flinch at most smaller character's punches and almost all rush moves will ricochet off them before they can do anything. This means characters like Hercule and Videl are almost completely helpless against them.
** Also somewhat averted in that while they don't flinch to attacks, they can still ultimately be defeated by the smaller fighters, including the aforementioned Hercule and Videl.
* Generally averted in ''VideoGame/WorldOfWarcraft''. Giants are met pretty often and while they usually can easily stomp a lone adventurer of an appropriate level, the tactics for taking them down is to bring friends and kick it's ass as a team (of varying sizes). Your human- (or dwarf- or even a gnome- or a goblin-) sized 'tank' will weather the giant's stomping as well as he does normal-scale enemies'. Only few quests are centered on driving or riding another giant and wrestling the monster giants on their own scale - and in these cases the trope often plays in your favour in regards to normal scaled monsters.
* Subverted in ''VideoGame/AsurasWrath''. The first boss, Wyzen, grows to the size of a planet, then tries to [[FingerPokeOfDoom poke]] the man-sized Asura to death. Asura blows him up, and he is posthumously mocked by his allies for thinking it would work.
* ''VideoGame/NewSuperMarioBros'' introduces the Mega Mushroom, which transforms Mario into an invincible, screen-filling giant who can plow through even normally indestructible objects like pipes. Some bosses can at least manage to bounce Mario off of them if he walks into them, but if he stomps on them, it's a OHKO.
* ''VideoGame/SuperPaperMario'' has the Mega Star, which similarly makes the user giant and invincible, but also turns them into an 8-bit sprite.
** The power-up is amusingly turned against you by a savvy Koopa Troopa in a secret room in world 3-1. However, it ends up being a subversion as despite its ridiculous size, the Koopa is just as frail as ever and can be eliminated with a single hit of almost any manner of attack.
* Averted by giant Transformers Omega Supreme and Trypticon in ''VideoGame/TransformersWarForCybertron'', who despite their massive size advantages can be defeated by conventional Transformers. Played straight by Metroplex in [[VideoGame/TransformersFallOfCybertron sequel]] who is only once slowed by enemy assault.
* Averted in the ''VideoGame/{{Rampage}}'' series where the player controlled monsters are vulnerable to, not only missiles, but small arms fire. Of course it can take a lot to kill them depending on the player.
* In the ''VideoGame/ClashOfClans'' commercials, the Giants are portrayed as being colossal guys who laugh as cannonballs, arrows, and mortar shells bounce off of their skin. [[GameplayAndStorySegregation In the game]], they are only about three times bigger than a Barbarian and are just [[SuperToughness very tough]], not [[NighInvulnerability invincible]].
* Technically averted, but played straight in any practical sense in the "Hoth" level of ''Shadows of the Empire''. While you certainly ''can'' take a full AT-AT down with your blasters, it will take a really, really long time. Using your harpoon and tow cable to go for the legs is not only much faster and easier, but infinitely cooler.
* ''VideoGame/HenryStickminSeries'', in ''Stealing the Diamond'', growing to huge proportions using a Growth Mushroom from Super Mario also renders Henry bulletproof. Downplayed since a cannonball does manage to take him down.
* One level in ''VideoGame/HeartOfTheSwarm'' sends an endless wave of Gorgon-pattern battlecruisers at your base. They're so huge they're entirely invincible (your units can't even attack it), and must instead be brought down by activating dormant Scourge nests (the Scourge are flying suicide bombers), and even then the nests are expended after one shot.

* This trope is extensively used in macrophile stories. Some stories, artwork, etc. do try and avert it, though they just as often run afoul of the SquareCubeLaw. Most handwave it or ignore the issue entirely for the sake of RuleOfSexy.
* Averted in ''Literature/TheSalvationWar'', where despite both the Demons and Angels being much larger than humans, they go down easily due to modern weaponry.
* ''{{Literature/Worm}}'': the only way to fight an [[{{Kaiju}} Endbringer]] is to throw hundreds of [[SuperHero capes]] at it at the same time. No gun, explosive, nuclear bomb or other human weaponry can harm it, save for AppliedPhlebotinum. Fenja and Menja, Kaiser's two henchwomen, are a much more literal example. They can increase their physical size, and cause all damage to them to scale inversely to their size--the bigger they get, the less hard they get hit.

[[folder: Western Animation ]]
* An episode of ''WesternAnimation/DextersLaboratory'' plays with this one: they accidentally awaken a giant Kaiju monster (it specifically happens in Japan, so it's a clear parody). The monster stomps all over a variety of superheroes and small superweapons and isn't defeated until they assemble a giant Anime/{{Voltron}}-esque robot. Though that was supposed to be an Aesop about family togetherness more than giant robots.
* ''WesternAnimation/ReBoot'', episode "Nullzilla" - which played off kaiju and mecha movies. The monster had to be stopped by creating a CombiningMecha.
* In ''WesternAnimation/TheSimpsons'' "Treehouse of Horror VI", giant advertising mascots go on a rampage. Predictably, conventional weapons are useless, but it turns out that [[YourMindMakesItReal our attention makes them real]] and they'll [[GodsNeedPrayerBadly keel over]] if we just don't look.
* If it comes to that, even ''baby'' dinosaurs in ''WesternAnimation/TheLandBeforeTime'' are harder than rocks of the same size. Although maybe it's more that those are some really sissy rocks.
* In ''WesternAnimation/MonstersVsAliens'', the army throws its entire arsenal at the giant alien robot without leaving so much as a scratch. And even after that, the President shoots a few rounds at it, just to show that he's a brave president. It is then that they decide to [[SummonBiggerFish sic the monsters at it]], but even ''they'' have a hard time defeating it. Considering that even the largest of the "monsters", [[AttackOfThe50FootWhatever Ginormica]]/Susan, is still tiny compared to the robot, this is justified.
* ''WesternAnimation/MyLifeAsATeenageRobot'' has Armagedroid, an older HumongousMecha designed by Dr. Wakeman, which fits this trope to a T. There are a couple of other [[MonsterOfTheWeek giant-sized threats]] throughout the show, but Jenny is able to beat them with some sort of force.
* Despite the aversion in the American ''Godzilla'' film, ''WesternAnimation/GodzillaTheSeries'' plays this straight. Godzilla in this series, is now capable of taking multiple hits from human ''AND'' alien weaponry. Not only him, but the [[MonsterOfTheWeek other monsters that appeared in the series]]. The only time they would die is by Godzilla or the Leviathan alien's weapons. And fighting each other.

[[folder: Real Life ]]
* Perhaps not as ridiculous a trope as it seems; a 50 meter tall, 20,000+ ton monster would most certainly ''need'' to be made of a very strong and durable substance, simply to ''[[SquareCubeLaw keep itself from falling apart at the seams]].'' Any monster that huge that was so flimsy as to be vulnerable to conventional weapons would be squashed by its own mass before we'd ever need to fire a shot. If on the odd chance you ever do [[TemptingFate meet a kaiju IRL]] and it doesn't collapse into jelly the moment it steps out of the ocean, you can safely assume this trope is in effect.
* Considering a simple hunting rifle can bring down an elephant, this is definitely not TruthInTelevision, even in the rare cases there are big things to shoot at.
** With a much more relative definition of "giant", this applies to all macroscopic life. Nearly anything can be taken down by an infection by much smaller organisms (such as bacteria or viruses).
** They are resistant to many small arms fire, that is what [[{{BFG}} elephant guns]] are for.
*** Elephant guns aren't strictly necessary for elephant hunting. In the olden days of unregulated slaughter for ivory many an elephant was killed with the lowly 7x57mm hunting cartridge, today now mostly used (at least in the United States) to bring down the relatively tiny whitetail deer. The main advantage of said "elephant guns" was that they could bring down very large game more quickly and more reliably. You could kill an elephant with a 9mm pistol if you had to, but it'd take a while (not as in shooting it until it dies video game style, but rather in waiting for it to bleed out, or with less severe injuries, wait for an infection to develop, since a small cartridge would have a hard time piercing the skull or penetrating to an internal organ). A more powerful firearm has the advantage of being able to bring forth a quicker death from farther away (which helps considering that said elephant may be trying to kill you), but once it dies, dead is dead one way or another.
** Whales can be killed with a simple harpoon, but its not as easy as it seems as they need to nail it at the right spot to make it effective. Then came grenade harpoons.
*** The old harpoons of both early whaling ships and pre-Industrial hunters such as the Inuit did not deal the whale a mortal wound. What worked was the droge, aka drug or drugg, a giant, very buoyant device attached to the harpoon. When the whale dove, it would fight any droges attached to it until it tired, was dragged to the surface, and there finished.
*** Whales are a straight example of this trope. Harpoons were not typically used to kill at all, they were used to anchor the boat to the whale so the whale couldn't escape; the kill usually came from repeated stabs with a whaling spear, and could take an hour or several hours even after stabbing the whale for it to die, as the massive reservoir of blood causes the whale to take some time to expire.
* RealLife massive vehicles of both civilian and military types are largely immune to or not significantly compromised by most small-arms fire, which is the reason that specialized anti-vehicle and anti-materiel weapons (which often have firepower on the same scale as the vehicles themselves) exist. Giant aircraft are slightly more susceptible due to the mechanical balancing act that keeps them aloft but a platoon of infantry would still need a ''lot'' of lucky assault rifle shots to down a heavy bomber if it somehow came within range.
* The biggest of dinosaurs are thought to have adhered to this trope at least somewhat. At their adult size, animals like ''Argentinosaurus'' would likely have had little to fear from predators, and the few predators that could fight them still had to be careful and couldn't guarantee that their attacks would be effective. In essentially a RealLife lampshading of this trope, one sauropod closely related to ''Argentinosaurus'' was named "''Dreadnoughtus''", which translates to [[AwesomeMcCoolname "Fears Nothing"]].
