->''"I'm the caster, y'know! It's like I'm a cannon made out of glass. Like a... y'know, like a dainty figurine so ornately decorated you can't imagine how something so fragile manages to exist in this brutal, ugly world... And it makes you weep."''
-->-- ''Webcomic/EightBitTheater's'' '''Black Mage''', on himself

%% One quote per page, thanks. Additional entries can go on the Quotes tab.

In short: they can dish it out, but they can't take it. The Glass Cannon is characterized by insane attack power coupled with pathetic defensive ability.

Prevalent in {{R|olePlayingGame}}PGs and {{fighting game}}s, as the cast needs to be big enough that "takes hits like a chump" becomes a viable character trait. In [=RPG=]s, the Glass Cannon tends to be a SquishyWizard. Not all {{Squishy Wizard}}s are completely Glass Cannon, though. A SquishyWizard still can have decent or good ''magical'' defense but abysmal physical defense. Artillery or archer units in RealTimeStrategy and TurnBasedStrategy games also tend to have this trait, as they're meant to be far away from combat, or at least in the back of the formation. If a boss happens to be a Glass Cannon, that's a RushBoss.

Make the Glass Cannon incapable of taking ''any'' punishment at all and you've got a OneHitPointWonder. A matchup between two of these usually results in RocketTagGameplay. When the enemy tries to take out the Glass Cannon as fast as possible, it's ShootTheMageFirst.

Glass Cannons often overlap with the FragileSpeedster; characters of that type tend to put out high damage and dodge most incoming attacks, but go down quickly if they do get hit. Also often overlaps with LongRangeFighter, using range to keep out of harm's way. The direct inverse of StoneWall, who takes it but can't dish it out. Compare and contrast MightyGlacier, who can dish out at the expense of speed rather than toughness, and LightningBruiser, who can do the same without sacrificing anything. A vessel mounted with a WaveMotionGun may have some aspects of this immediately following its use, as the PowerLimiter of the weapon often is that it leaves the vessel defenseless for a time. See also: CompetitiveBalance and PVPBalanced.

[[IThoughtItMeant Not to be confused with]] actual cannons made of glass, which would be {{Glass Weapon}}s.


* GlassCannon/VideoGames


[[folder:Anime and Manga]]
* Accelerator from ''ACertainMagicalIndex'' is a strange example of this. Normally he's {{Nigh Invulnerab|ility}}le thanks to his ability to redirect all vectors within a certain radius of him (if he has an oxygen tank a ''nuke'' wouldn't faze him). He's also incredibly powerful to the point of being able ''casually break a continent'' if sufficiently pissed. However, once that fancy ability of his is bypassed he's nothing more than a scrawny teenager waiting to be pummeled.
* Shin Kazama of ''Manga/{{Area 88}}'' fits this trope. [[spoiler:He deals a nasty blow to Saki's head during a temporary psychotic rage, but Mickey floors him with one punch.]]
* If it weren't for their HealingFactor, the Titans in ''Manga/AttackOnTitan'' would be incredibly easy to destroy. Sure, they're huge, and if they grab you, you're dead, but their bodies are incredibly light and fragile. This is especially true of [[spoiler:Eren]], who often hits things so hard, his bones actually snap apart from the impact and have to regenerate. This is best showcased when he punches a Titan in the head so hard, he knocks it right off and sends it flying into a church, but his hand is destroyed in the process.
* Shiki, TheDragon and (sort-of) SquishyWizard from ''Manga/BlackCat''. His ''normal'' attacks do more damage than anything this side of TheHero, the BigGood, and the BigBad's ''final'' moves, but he goes down with one ''pistol-whip'' from [[TheHero Train]].
* ''Manga/{{Bleach}}'':
** Ikkaku's sword is unpredictable, dangerous, and incredibly powerful. However, it breaks easily because its shikai form is a wooden spear, and the bankai's overpowered force makes itself brittle. Ikkaku is refusing to use his power correctly and has been chastised for that by Iba; It's heavily implied that his misuse of his power is why the weapon keeps breaking so easily; the Zanpakutou inventor, Nimaiya, openly tells Renji and Ichigo that Zanpakutou which are not correctly used will break easily. Ikkaku himself is not this trope.
** Ran Tao in the anime filler Bount Arc is a very skilled spell user but her stamina is heavily compromised [[spoiler: by [[OlderThanTheyLook her extreme age]]]].
* The Japanese National Team in ''Manga/CaptainTsubasa''. They've got excellent scorers in Tsubasa, Aoi and Hyuga as well as great GK's like Wakabayashi and Wakashimazu, but one of their biggest flaws is how easily their defense can be torn and the rival teams can try their luck at scoring. And since the two Waka GK's are prone to {{Game Breaking Injur|y}}ies...
** Single player version: Jun Misugi. Excellent strategist, very dedicated, great at teamwork, marvelous scorer... and with pathetic stamina due to being an ex-IllBoy. Hence why he's seen more often than not in manager positions and doesn't play until it's mandatory.
* Manga/DeathNote: Light Yagami and all other Deathnote users definitely qualify. They can kill anyone whose face and name they know but are not more bullet resistant than anyone else.
* Wisely of ''Manga/DGrayMan'' can be considered this compared to other Noah (they are all physicially superhumans anyway). His power allows him to OneHitKill anyone by [[YourHeadASplode crushing their brain with a mere glance]]. However when he indirectly received an attack on his head he was stunned for the rest of the arc. Besides he declares himself as "not a fighter".
* May of ''Manga/FullmetalAlchemist'' has quite a few different ranged attacks with her alkahestry, but is one of the least durable characters, partly the result of being a young girl.
* In ''Manga/HajimeNoIppo'', minor character Eleki Battery who fought Kimura is definitely one. He has enough power to knock Kimura down in one blow, however, all Kimura needed to do was land one hit to his body to knock him down.
** Also Ryuichi Hayami, who's got very good counters and speed as well as strength... but one well placed punch and he's out. [[spoiler:This gets so bad that, when Kobashi manages to deal him a REALLY well-placed hit in the jaw, the injury he sustains forces him to retire.]]
* ''Manga/JoJosBizarreAdventure'':
** Diavolo's Stand in part 5, King Crimson, is one of (if not THE) most powerful Stands in terms of raw striking power, with an A rank in Power and Speed. However, it has an E rank in terms of durability. This is why Diavolo tries to end his fights with a single strike, as he can't survive an extended assault.
** By part 6, Jotaro's Stand, Star Platinum, has degraded from LightningBruiser to this. It maintains its legendary speed and strength, but Jotaro's age combined with [[spoiler:the strain inflicted on him when he uses its [[TimeStandsStill time stopping power]]]] resulted in its durability dropping from rank A to E.
** Stand users in general, with a few exceptions like DIO, aren't any tougher than those without powers; so any with a particularly potent offense is going to fall into this if they start taking direct hits. Most noticeable with [[TeamPet Iggy in Part 3]], who has a very powerful stand with a wide range of abilities, but is still a small dog with all the fragility that one would expect. [[spoiler: Leading to him being mortally injured from a few strong kicks.]]
* ''Franchise/LyricalNanoha''
** Fate's [[SuperMode Sonic Drive]] form introduced in ''Anime/MagicalGirlLyricalNanohaStrikers''. It improves on her original [[FragileSpeedster Sonic Form]] by giving her a lot of oomph to complement the speed increase, boosting her magic powers to astounding levels and letting her access [[SwissArmyWeapon Bardiche's]] [[BifurcatedWeapon Riot Zamber]] form. But much like the original Sonic Form, all of this comes at the cost of armor, so all it'll take is one good hit to make her fall. Not that it proves to be much of a detriment; so far, only Erio has managed to land a hit during a mock battle in ''Manga/MagicalGirlLyricalNanohaVivid'', where it indeed wiped out most of Fate's HitPoints.
** Hayate has also shades of this: her spells range from nuclear explosion to... [[PersonOfMassDestruction bigger nuclear explosion]], but it comes with looooooong casting time and inability to take hits. She even said Caro would win against her in one-on-one. This is counterbalanced by the fact that Hayate almost never fights one on one; even without her other allies, most of the time she still has Reinforce with her, who can separate and hold off a target with a slew of not quite as powerful, but quite a bit faster spells while Hayate prepares her WaveMotionGun.
** Lutecia Alpine is an S-rank summoner who, in ''[=StrikerS=]'', is capable of summoning insects that rival Caro's powers, but has hardly any moves with which to protect herself. However, as of ''[=ViVid=]'', she appears to have developed the magical capabilities to fight alone well enough to enter the tournament alongside Vivio and her friends.
** The Numbers from ''[=StrikerS=]'' are very powerful, but they can't take hits that well and most of them seem to not have defense skills. Their teamwork makes them dangerous, but if you're strong or skilled enough to take one after another down, then it's not a problem. In the GrandFinale, all Numbers are defeated by one or a few hits.
** Like Fate, Micaiah Chevelle from ''[=ViVid=]'' is this overlapped with FragileSpeedster: she has a Barrier Jacket (or Knight Clothing) which is designed to give her immense speed for minimum defense. This speed supports her extremely powerful sword attacks greatly, but her lack of defense becomes a lethal disadvantage against LightningBruiser Miura who has melee versions of Nanoha's [[ThereIsNoKillLikeOverkill Starlight Breaker]].
%%* In ''Manga/MahouSenseiNegima'' traditional style mages tend to be like this, which is why they have partners to guard them from their opponents while they prepare their big spells. The mark of the highest-level mages is that they grow tough enough to move past this and are powerful enough not to need the protection.
* Alyssa of ''Anime/MaiHime'' has the ability to cause devastation on a large scale with her Child, Artemis, but unlike other Himes, does not have an Element to protect herself, instead relying on Miyu's assistance.
* [[Anime/MobileSuitGundam00 Tieria Erde's Gundam]] in TheMovie, the Raphael, is this. It is equipped with [[{{BFG}} Big Friggin']] {{Wave Motion Gun}}s that can also function as {{Attack Drone}}s. However, due to said Gundam not being equipped with real GN Drives as well as the lack of resources used while it was being created, all defensive capabilities were sacrificed in favor of its offense. His earlier Gundam Nadleeh qualifies as well: it's essentially a FragileSpeedster with the Exia's close-combat attack power. Naturally, it's only used in emergency as it's a DualModeUnit, its other form being [[MightyGlacier Gundam Virtue]].
** The [[MechaExpansionPack GN Arms]] from the first season too. Lockon absolutely owned everyone with it until Ali incapacitated him with a single well-aimed shot at his beam cannon. Then it turned out the Gundam piloting the exoskeleton is tougher than the actual exoskeleton! Another example of this trope is the Gadessa: its main weapon is a WaveMotionGun with ridiculous range... and not much armor. It still has a backup weapon and a beam saber but its defensive capabilities are nowhere near those of the others, as Lockon took it out in the final battle [[SugarWiki/MomentOfAwesome with a point-blank burst from his Gundam's sidearm after]] PlayingPossum [[KickThemWhileTheyAreDown to lure it close]].
** Even seen in ''Anime/MobileSuitGundamMSIGLOO'' during the gravity front. Zaku's are portrayed as having tremendous and devastating firepower...but one direct hit from a tiny tank or missile team can still one shot them. Fortunately it seems that even non new type mook Zeke's can DodgeTheBullet.
* ''Manga/MyHeroAcademia'':
** Seiji Shishikura is a pretty extreme glass cannon. His power, "Meatball," allows him to [[BodyHorror reshape the flesh of anyone]] he comes in physical contact with, which pretty much instantly immobilizes them. He can even [[DetachmentCombat detach chunks of himself and shoot them at others]], which will adhere to them. In his introduction, he effortlessly inflicts [[OneHitKill one-hit KOs]] to at least a dozen heroes. However, if he so much as takes damage, anyone he's shaped into meatballs will revert back to normal. That is, for him to be effective, he cannot be hit by any attack, no matter how small.
** Kaminari's power is the ability to discharge an enormous amount of electricity into the surrounding area. The problem is, once he does this, the power basically fries his brain and turns him into an idiot, meaning that he gets one shot before becoming totally useless for the next hour or so. And he's not any physically stronger than a normal human, making him something of a sitting duck. Later on, he starts to train specifically to avoid this issue.
%%** Midoria is the very definition of a glass cannon, especially in the beginning of the series; due to the lack of control of his new quirk, any attack using it would have a recoil with the same intensity of the attack since Midoria's body wasn't strong enough. It usually ended up with a completely broken and deformed limb.
* Itachi Uchiha is basically this in ''Manga/{{Naruto}}''. Despite having three of the most powerful attacks in the entire manga, Itachi's base arsenal lacks versatility. Not only that, a sufficiently [[SuperStrength strong character]] could OneHitKO if they got close. His stamina is particularly low as well, meaning he can't fight for extended periods. Those three powerful attacks? They cost more than ''30%'' of his total chakra, meaning he can't spam them like his brother Sasuke can.
* Nami from ''Manga/OnePiece''. Her [[WeatherControlMachine Clima Tact]] can make very dangerous [[ShockAndAwe lightning attacks]], and while they take some time to charge up, her offensive power with these makes her one of the most dangerous Straw Hats. She is one of the very few people who can hurt Luffy with [[ArmorPiercingSlap a regular punch]], though it is because she [[ItRunsOnNonsensoleum "beats up his spirit"]]. Her durability, however, is very puny and no better than that of real life human.
** Early series baddie Kuro is this as well. He can slice people up like Salami, and his ''[[FlashStep Shakushi]]'' ability makes him [[FragileSpeedster damn near untouchable]]. However, he just can't take a hit. When Luffy slows him down, the fight ends very soon after.
** King Elizabello II of the Prodence Kingdom's signature attack, the King Punch, can make a hole in an enemy fortress wall, though it takes an hour to charge so he needs to be protected while preparing it. When tried out in an arena, it basically ''destroyed'' it, and would have killed the audience if a BarrierWarrior hadn't been standing by. Unfortunately, he's nothing special in terms of toughness, getting one-shotted by the same barrier warrior immediately afterwards. With a ''punch'', at that.
* ''Manga/OujaNoYuugi'': the magic-wielding strategists are powerful, but fragile glass cannons, and have to be protected by their generals on the battlefield.
* The BigBad of the final arc of ''Manga/RanmaOneHalf'' has powers bordering on a PersonOfMassDestruction and he can tank ''[[KiManipulation Ki Attacks]]'', but a rather pampered life has lead him to be rather weak against ''physical'' attacks. Of course this is just compared to the completely MadeOfIron fighters in most of the series (he was called a wuss for being ''moderately injured'' by a boulder... being thrown by tornado winds that were drilling into the ground and altering the course of an underground river).
%% ** Cologne has some elements of this as well. Given that she's one of the two most prominent MiniatureSeniorCitizens and a ''very'' OldMaster (three hundred years in the anime), this might be somewhat explainable.
** Akane Tendo as well. Though she can dish out punches with the best of them, she has nowhere near the healing speed or toughness of any of the other characters; while she is too skilled to be TheLoad in an actual fight, she is still regarded by some as a DamselScrappy because she insists on getting into a fight, but somebody (mainly Ranma) usually has to keep an eye on her because she can't take the hits they can.
%% ** Cologne's granddaughter Shampoo is even worse when it comes to taking hits, even when you don't take her [[BalefulPolymorph curse]] into account. She often falls down with one good hit.
* Pikachu fits this trope well in ''Anime/{{Pokemon}}''. Massively powerful attacks? Check. Tendency to go down quickly in a fight? Oh yeah.
* ''Anime/RanpoKitanGameOfLaplace'': Akechi can dish out a lot of damage due to his [[AllThereInTheManual correspondence karate]], but breaks bones after hitting tougher and older opponents.
* Similarly, Hisashi Mitsui from ''Manga/SlamDunk'' is one of the best 3-point scorers in Japanese HS basketball. But around 3/4 of an intense game, he's almost completely knocked out and unable to merely ''walk'' outside the basketball fields.
* ''Anime/SpaceBattleshipYamato'' has the Super Battleship Andromeda. All the ships in the Andromeda fleet have double wave motion guns but still get easily destroyed just by the force of the White Comet's vortex.
%% * Louise from ''LightNovel/TheFamiliarOfZero''. Just like the ''Manga/MahouSenseiNegima'' example, her partner/familiar Saitou is here to protect her while she prepares her insanely powerful spells.
* Lillidan Crauser of ''Manga/ThePrinceOfTennis''. He is extremely powerful, able to curb-stomp a bloodshot Kirihara using even greater violent play than him. However, he lacks stamina and defense. Considering this it comes as no surprise that Devil Akaya completely trashes him in a matter of minutes.
* In ''LightNovel/TheLegendaryMoonlightSculptor'', the main character Weed considers his non-combat title-class to be this, he calls his class a "glass sculptor" as his unique attacks do a lot of damage, but because he is a crafter class, he cannot equip heavy armor, and does not receive the ordinary damage reducing skills of, say, a warrior.
* King from ''Manga/TheSevenDeadlySins'' is capable of dispensing incredible attacks with his MorphWeapon. However, he is a massive SquishyWizard as he can't even physically beat an old man with a bad back in unarmed combat.
* In ''Manga/TokyoGhoul'', this is the defining characteristic of the [[CombatTentacles Rinkaku]] Ghouls. Their kagune possess incredible striking power, but the cellular structure is brittle and easily damaged.
* In the first season if ''Anime/YuGiOh'' (where the card game was the least like its RealLife equivalent) both Zombie and Machine-Type Monsters were described like this, incredibly strong on offense but really bad at anything else, especially defense. (Of course, the actual game isn't like this at all, at least not all the time.)
* In ''Anime/YuGiOhArcV'', Shun Kurosaki is not only a skilled duelist, but very strong, skilled, and agile in hand to hand combat. However, he's laughably easy to knock unconscious and gets injured frequently. His English voice actor Matt Shipman has commented on this shortcoming a few times.

[[folder:Comic Books]]
* ''Comicbook/XMen'':
** Many telepaths, such as Professor X, have powerful PsychicPowers but [[SquishyWizard are extremely poor at defending themselves]], and aren't of much use against opponents immune to telepathy (like robots).
** ComicBook/{{Cyclops}}' EyeBeams are devastatingly powerful, but if anyone actually hits him he's just as vulnerable as any non-powered human. Well, any non-powered human in peak physical condition with iron willpower and light body armor, but still -- a lot of X-Men fight scenes start with Cyclops getting punched out or shot with regular bullets, because (from a writing perspective) otherwise he could settle the whole business with a look.
** And, ComicBook/{{Storm}} may have god-level power, but up close, she's hard to hit, but just as easily hurt as anyone else. Same with most of the other X-Men whose specialty is offensive power.
* In the show ''Series/{{Angel}}'' the Senior Partners are built up to be this great unmatched evil that span multiple dimensions and can bring about the apocalypse. In the comic book spin-off ''Spike'' we see what the actual Senior Partners look like: 15 ft tall demons that can fire deadly lightning bolts. The problem? [[spoiler: The Senior Partners are relatively fragile compared to other Buffyverse Big Bads. Spike fires at one with a pair of machine guns and it's left crying in the corner letting our heroes get away in defeat. It's revealed that the reason the Senior Partners conduct their evil scheming though law firms is that they lack the brute strength to take over worlds through sheer force.]]
* The same is true of Marvel magic users like Comicbook/DoctorStrange, ComicBook/ScarletWitch, or [[ComicBook/YoungAvengers Wiccan]]. They can do frightening things to time and space with little more than a gesture and some concentration, but they can also be rendered helpless by a TapOnTheHead, drugs, being overwhelmed by bodies, being distracted in mid-spell, or simply being BoundAndGagged.
* ''ComicBook/FantasticFour'' member Human Torch's flame powers give him high movement speed and an offensive edge. Unlike his allies, though, he typically lacks any way to use his powers to defend himself other than flying out of the way. This example [[DependingOnTheWriter changes based on who's scripting the book]] -- Johnny's also been shown to make himself bulletproof by melting the slugs before they hit; on other occasions, he's pulled the same thing on various flammable or meltable objects up to a bulldozer that was thrown at him by ''ComicBook/SheHulk''.
* ComicBook/{{Zatanna}} of Franchise/TheDCU can kill people with a (backwards) word (not that she ever has, she is a superhero). Only the stronger magical, divine, or cosmic beings in the DC universe can resist her powers. However, she isn't any more durable than most humans and can be taken down with a single well-placed punch. Overlaps with SquishyWizard. In ''ComicBook/IdentityCrisis'' it is even explicitly mentioned in the narration-bubble: She is the most powerful member of the team, ''if she can get the words out.'' Slade Wilson (ComicBook/{{Deathstroke}} the Terminator) pokes her in the stomach, so lightly that it does not even hurt that much, but once she begins to vomit from the damage to her liver she is out of the fight.
* [[http://x-men.wikia.com/wiki/Prism Prism]], an on and off member of the ''Comicbook/XMen'' villain Mr. Sinister's Marauders, is ''literally'' made of glass. He can store light and energy (such as sunlight or Cyclops' optic blasts) and redirect it to devastating effect. But he is still made of ''freaking glass''. Jean Grey [[DeathIsCheap killed him once]] by throwing him into a wall (not even that hard).
%% * Sizzle from the third ''Comicbook/{{Legion of Super-Heroes}}'' continuity is practically a literal cannon, needing a steady power source (ammo) to feed her energy projection abilities. The awkwardness in having to both provide power and cover to Sizzle while watching your own back is the reason she was sent to the Legion Auxiliary along with her StoneWall friend Turtle.
* Emp's hypermembrane suit from ''Comicbook/{{Empowered}}''. Amazing SuperStrength, flight, energy beams, who knows how many other powers...and the durability of wet tissue paper. [[GoodThingYouCanHeal Good thing it can repair itself.]]
* The ''Franchise/SpiderMan'' villain [[ComicBook/DoctorOctopus Dr. Octopus]] may have control of four powerful and deadly metal arms, but he's otherwise a normal, somewhat out of shape human. Once the super-strong Spidey gets past his formidable defenses, Doc Ock goes down pretty quickly. This ultimately led to his [[DeathIsCheap death]] as his body couldn't take the punishment various superhumans had dealt him any longer.
* In ''ComicBook/{{Uber}}'', the Nazi "blitzmensch" superhumans have EyeBeams powerful enough to demolish towns and sink warships at ten-kilometer ranges, but their bodies are as fragile as a normal human's, allowing the stronger "panzermensch" to rip them apart at close range.
* ''Franchise/{{Superman}}'': The Daxamites are an alien race related to the Kryptonians that share many of their powers under exposure to yellow sun. As such, Daxamites are capable the same potential of destruction as their counterparts (made even worse by the race tendency to be {{Absolute Xenophobe}}s and not refraining from minimizing damage around them), the difference is that their [[WeaksauceWeakness main weaknesses]] is exposure to lead, which is even deadlier than exposure to Kryptonite since Kryptonians recover quickly after being moved away from it - once lead is inside Daxamites' body, its not going away and it will slowly kill them. While they can be as strong as Superman, Daxamites can be easily brought down using just conventional firearms.
* ''ComicBook/ScottPilgrim'': Todd Ingram, Ramona's third ex, is even more powerful than [[BigBad Gideon]] due to his immense psychic powers, yet after [[spoiler:being depowered by the Vegan Police]] he goes down to a single headbutt from Scott.

[[folder:Fan Works]]
%% * In ''Fanfic/QueenOfAllOni'', the old Oni rulers fit this, while the magic snake they conjured to attack Tarakudo was impressive, due to their advanced age and decaying power, he was easily able to stop it and kill them.
* In ''FanFic/AnEntryWithABang[=!=]'', the marauding pirates with their ''{{TabletopGame/Battletech}}''... uh, tech... are somewhat confused by the fact that while Clancy-Earth has highly effective BVR capability, their warmachines can't take hits worth a damn.
* The ''Series/{{Firefly}}'' fanfic ''Fanfic/{{Forward}}'' puts an emphasis on River being one of these; she's portrayed as [[FragileSpeedster fast]] and powerful, but one good hit puts her down, which happens several times in the story.
* In ''FanFic/{{Fractured}}'', a ''Franchise/MassEffect''[=/=]''Franchise/StarWars''[[spoiler:[=/=]''[=Borderlands=]'']] [[MassiveMultiplayerCrossover crossover]], some starships rely on their {{BFG}} destroying all opposition before it can shoot back, having only light armor. In the [[FanFic/SovereignGFCOrigins sequel]], Jack and Brick start off this way with their [[BadassTeacher teaching style]], only to realize later on how problematic the technique could be.
* Lightning Bolt is one of these in ''[[Fanfic/AceCombatTheEquestrianWar Ace Combat: The Equestrian War]]''. She is the only pony of the main heroines to have a powerful special attack (Shining Spark), but she is prone to being injured during prolonged battles.
* Devastator in ''FanFic/TheMeasureOfATitan'' is practically the paragon of this. His powers are theoretically capable of splitting a planet in half, and he can use them to fight multiple high-level metahumans at once, but he is as fragile as any normal human, and heals as slowly also.
* Midori is one in ''FanFic/SevenDaysSurvivor'', as per WordOfGod and comments from the other characters. [[VideoGame/{{Persona3}} Minato]] explicitly includes a dedicated healer (Either himself or Yukari) on the team when Midori is in play simply to keep her up.
* In ''[[Fanfic/RyuugisTheGamesWePlay The Games We Play]]'', the White Tiger style is this - massive boosts to offence and mobility, but no buffs to defence. It left practitioners capable of dealing lots of damage, but being no tougher than an ordinary human. This was only slightly mitigated by the later development of the White Tiger's Hide, and is exacerbated by the CastFromHitPoints nature of the style's two strongest skills. As a result, while a master of the style is [[Creator/WilliamBlake a tiger, tiger burning bright,]] he will not last the night. Jaune gets around this problem by picking up other defensive skills.
* The ''Franchise/MassEffect'' story ''FanFic/MesozoicEffect'' introduces a whole class of ships that follow this rule, known as battlecruisers. Like their historical counterparts, they mount the firepower of a dreadnought on the frame of a cruiser, but stuffing in such a [[FixedForwardFacingWeapon huge spinal gun]] leaves almost no room for armor. Mass production of these ships is apparently one of the things the Treaty of Farixen was designed to prevent. The [[EverythingsBetterWithDinosaurs Pangea Alliance's]] frigates also fall into this category, as they forgo armor for [[FragileSpeedster superior engines]] and [[MacrossMissileMassacre racks upon racks]] of [[NukeEm fusion missiles.]]
* Jen in ''Fanfic/PrincessOfTheBlacks'' has functionally infinite magical reserves due to being able to channel the Earth's magic, only limited by how much she can channel at once. However, not having a magical core of her own makes her far more vulnerable to others magic. A spell designed to have someone instantly awake and alert sends her into an adrenaline fueled panic.

* ''Film/{{Battleship}}'' correctly shows that modern-day missile destroyers are this. They carry lots of missiles and the Aegis system allows them to MacrossMissileMassacre an enemy, but they lack any real armor to protect them from return fire. The [[PointDefenseless CIWS]] guns do an admirable job trying to protect the ships from the alien attack, but the enemy employs the MoreDakka tactic to overwhelm the defenses. Their aforementioned Aegis systems also failed to work given that the attackers were often too close and failed to properly show up on radar.
* Katniss of ''Film/TheHungerGames'' is a quickdraw with a bow and takes out several competitors in seconds. Compared to the opposition, she is untrained in how to fight up close, and is slowed down significantly by relatively minor injuries.
* ''Film/XMenFilmSeries'': The ultimate example is Professor Charles Xavier, whose considerable telepathic powers are generally taken UpToEleven by allowing him to take control of minds halfway across the world, [[spoiler:potentially commit ''genocide'', and even transfer his consciousness to his comatose twin brother]]. He can't take any more punishment than any other human, though, and he's paralyzed from the waist down and restricted to a wheelchair.
** ''Film/XMenApocalypse''
*** Professor X is the second-most powerful mutant [[spoiler:(third after Jean Grey accesses her Phoenix Force)]], and the story even makes a point about how a "god" is incomplete without his psychic ability ("To be everywhere, to be ''everyone''"). But because his telepathy is ineffective against Apocalypse's PsychicBlockDefense, Charles is ''totally'' defenseless; he's no more physically resilient than any other human, and as a paraplegic, he can't even ''try'' to run away from his captor.
*** Quicksilver's SuperSpeed, which normally gives him a huge advantage over his foes in combat (Apocalypse is flying through the air when Peter is punching him),[[note]]in physics, Mass x Acceleration = Force, so Quicksilver's ability generates SuperStrength in a fight situation[[/note]] is nullified after [[spoiler:Apocalypse traps his foot into the ground and breaks his leg]]. In the vicious hands of the god-like mutant, Maximoff is as fragile as a toy.
* Metro in ''Film/RealSteel'' would be a Glass Cannon, as he beat down Atom badly but got taken out by one hit.
* ''Franchise/StarWars'' has TIE Interceptors, whose armament - twice or even occasionally thrice that of the more widespread TIE Fighters - means they actually represent a threat... for a short while. Their shielding is no better than that of the Fighters (that is to say, they have none whatsoever), so they break apart as soon as someone shines a laser pointer at them. [[FridgeLogic Though if one actually watches the films]], Rebel fighters actually die just as easily when [[PlotArmor not flown by main characters.]] So one wonders what those shields are for.
* In ''Film/PhoenixWrightAceAttorney'', [[spoiler:the flashback to the DL-6 incident shows that young Edgeworth was able to bite Yanni Yogi hard enough to distract the baliff from hitting his father, and later threw a gun at him hard enough to knock the guy out. When Yogi shoves him hard enough to be knocked against a wall though, Edgeworth collapses almost immediately]]. Given that he's a kid, it's pretty justified.
* In ''Film/PacificRim'', the Japanese Jaeger, Coyote Tango, has huge retractable cannons mounted on its shoulders, but is apparently the most lightly armored of the Jaegers.
* In ''Film/TheWorldsEnd'', the Blanks have inhuman strength and agility, but you could burst their heads open with a well-thrown punch. This probably explains why our heroes, a bunch of a middle-aged, out-of-shape men, are able to deal with crowds of them.
* In ''Film/GodzillaVsMegaguirus'', Megaguirus is so fast she can FlashStep circles around Godzilla, and strong enough to knock him around and pick him up. Once Godzilla gets a good hit in however, she's finished.
* In ''Film/TheMightyDucks'' trilogy, the titular team provides an athletic example. They use lots of ConfusionFu on offense, but their defense is rather lacking. This is pointed out in the third movie by Coach Orion, who teaches them how to play "two-way" hockey.
--> '''Orion:''' I've seen your tapes. I know you can score goals; I just don't know if you can stop them.

* In ''Literature/TheDresdenFiles'' Harry mentions that wizards are like this; for all of the magical weight they can throw around, they still need all of their squishy internals to work. He also frequently complains that nearly all supernatural creatures are MadeOfIron at the least, cementing this trope
* In ''Literature/HonorHarrington'' there are several ships like this. At one end of the extreme are outdated Solarian Navy ships which put more focus on offensive weapons than counter missiles and point defense lasers. Likewise, Maya's Arsenal ships which are capable of carrying thousands of long range missiles, but are just converted freighters and have no defense at all.
** Special mention to HMS ''Wayfarer'' and her sisters: converted freighters, sluggish and armored for crap, but carrying super-dreadnought-class main guns capable of carving up a battlecruiser like a roast turkey, [[TheBattlestar a complement of light-attack craft]] capable of laying down significant hurt in their own right, and, oh yeah, the first roll-out of the [[MacrossMissileMassacre Manitcoran Missile Massacre]].
** Honor's first cruiser, the HMS ''Fearless'' was refitted with weapons that would allow it to kill far bigger ships. But the weapons' short range and the lack of any decent defenses resulted in a single resounding success during the first fleet exercise, and getting 'destroyed' in every exercise thereafter once the opponents had realized the threat ''and'' decided to give some payback for the first success.
** The Manticoran [=LACs=] introduced in ''Echoes of Honor'' are armed with battlecruiser grade grasers, but they're not very survivable should an opponent decide to focus on them. In universe, [=LACs=] in general are described as "eggshells armed with hammers".
* Not surprisingly the Literature/{{Lensman}} universe plays with this one, but the vulnerable sluggers are always accompanied by copious numbers of their exact opposite - ships that are all shield and nothing else (sometimes not even a human crew). There are, however, usually large numbers of [[JackOfAllStats balanced ships]] in the same fleet.
* In the ''Literature/{{Bolo}}'' books, there are Enemy units that are just counter-grav platforms mounting [[WaveMotionGun Hellbores.]] They can be easily swatted by said supertanks, but can be a problem if allowed to attack. They aren't OneHitKill-capable, but the numbers are always on their side.
* Coinshots in ''Literature/{{Mistborn}}'' are a kind of [[MasterOfOneMagic Misting]] who have only one power: the ability to telekinetically shoot metal away from their bodies. This makes them able to dish out a ''ton'' of damage, since a Coinshot with a pouch of money is basically a human machine gun, but they have no greater ability to resist damage than anyone else. Have a half-dozen Coinshots protected by about the same number of Thugs (Mistings who can increase their strength, speed, and durability to superhuman levels) though, and you've got yourself a small but very effective army.
** Somewhat averted in ''Literature/TheAlloyOfLaw'', as firearms have become commonplace, and Coinshots are possibly the only Mistings who can reliably deflect bullets (Lurchers, who have the opposite ability, generally pull bullets toward a metal plate carried on their chest).
* Deathpoint in ''Literature/TheReckonersTrilogy'' [[ExactlyWhatItSaysOnTheTin can kill almost anyone just by pointing at them]] but lacks a "prime invincibility", meaning that he can be killed just as easily as anybody else.
* Leila in the ''[[Literature/NightHuntress Night Prince]]'' series. A human ordinarily couldn't hope to defeat even the youngest vampire, yet with her electricity whip, Leila once killed a group of five vampires. Before that, she took out a group of three. This is purely an offensive power, though; she's as fragile as any other human.
* ''Literature/TheHungerGames'': Despite being quick-thinking, agile, and a good shot with a bow and arrow, years of being underfed really limits how much stress Katniss's body can take.
* Deliberately invoked in the ''Literature/SixteenThirtyTwo'' series. When the USE attacks Denmark with ironclad warships more advanced than anything else at the time, Prince Ulrik counters by building a fleet of longboats armed with spar torpedoes. Being little more than large rowboats, they're easily gunned down by the USE navy, but they can be built sufficient numbers to [[ZergRush swarm the larger battleships]], and, if they get close enough, it only takes one good torpedo hit to disable an ironclad.
* Jade in ''Literature/{{Fallocaust}}'' is one of, if not the most powerful character in a [[WorldofBadass series full of them.]] However, he lacks the pure muscle of some of his brothers, and several characters manage to incapacitate him by virtue of getting a lucky hit in.

[[folder:Live-Action TV]]
* In an episode of ''Series/LoisAndClark'', ComicBook/LexLuthor creates a boxer that he believes can take on Franchise/{{Superman}}. The boxer delivers a flurry of punches that stagger Superman. For a moment it looks like Superman is actually on the ropes, but then he simply flicks the boxer in the forehead and knocks him out.
* Most space-faring vessels in the ''Franchise/StarTrek'' universe fall under this category if something ever happens to their DeflectorShields. ([[DeusExMachina It happens]] [[OncePerEpisode more often than you'd imagine]].) Watch the [[TheFederation Federation's]] [[TheBattlestar Flagship]] get [[CurbStompBattle roflstomped]] by an obsolete warbird thanks to shield sabotage [[http://www.youtube.com/watch?v=sLSJzOzNVfc here]]. [[spoiler:Mind you, turnabout's fair play, and the Klingons get [[OneHitKO one-shot]] after they lose their shields as well.]]
** In ''Series/StarTrekDeepSpaceNine'', Jem'Hadar Fighters are pretty much this. They're able to deal heavy damage, at least early on, with only a few bursts of their phased polaron beams, but a few phaser cannon shots or a single torpedo are enough to either cripple or destroy them. This is deliberate on part of the Dominion, with the Fighters being cheap but deadly throwaway ships with minimal and expendable crew, and no features that aren't essential to combat.
* ''Series/TheOuterLimits1995'' episode "The Camp" has super strong robots that are ludicrously fragile. An untrained woman can tear them to pieces.
%% * Lou from ''Series/ChoushinseiFlashman''. An ActionGirl functioning as the secondary muscles of the team. She [[KickChick relies on kick attacks more often]] as a possible way to conserve her physical strength.
%% * Luka Millfy from ''Series/KaizokuSentaiGokaiger'' is also this. In her case, she is not only the strongest fighter on her team, she's also the most evasive.
%% * Ian Yorkland from ''Series/ZyudenSentaiKyoryuger'' fits this due to his preference in long-range combat.
* In robot combat events, such as ''Series/RobotWars'' and ''Series/BattleBots'', full-body spinners (robots with a chassis that rapidly spins and has blades, spikes, or hammers attached to it) tend to fall into this category: While they are able to deliver some of the strongest attacks ever seen in robot combat, any opponent who can slip through their offense or can withstand multiple blows without breaking can easily and quickly render them useless. In particular is Mauler 5150, which is infamous for getting tipped upside-down by pretty much anything that its spinning doesn't wreck first, such as with [[https://www.youtube.com/watch?v=WS9i8JgLjTU a light tap from Jabberwock]].
** Any robot with a flywheel too. They're very devastating weapons, but also very heavy too, usually taking up 20%-25% of the robot's weight allotment. Designers, forced to shed weight to ensure it's light enough to compete, often go for shedding armour first. Flywheels also tended to have enormous recoil when they struck something, [[CastFromHitPoints causing damage to internal components]]. One of the best examples would be ''Robot Wars''' Hypno-disc, which became ''the'' reason bots had to invest on heavier armor after utterly tearing apart another bot in its very first match, and would generally mangle its opponents spectacularly. But it had the problem the rest of its chassis was rather frail and easy to shove around, and a bot with enough armor could simply outlast it by tanking its strikes until it tore itself apart. Most of its losses were from having taken so much damage even after a CurbStompBattle it had to battle with incomplete repairs.
** Nightmare from ''Series/{{Battlebots}}'' is one of the finest examples in robot combat. The details have changed over the years, but at its essence Nightmare's basically a ''monstrous'' vertical flywheel mounted on a spindly, easy-to-tip three-wheeled frame with exposed tires (although it did get wheel guards for the 2015 reboot). Whenever Nightmare fights, ''someone'' is leaving the Battlebox in pieces - [[SingleStrokeBattle usually depending on who gets the first hit]].
* ''Series/BabylonFive'' has the Centauri warships. Their firepower is high enough that they usually destroy their targets with one or two shots, and their rate of fire is high enough that a single Centauri battlecruiser overwhelmed the station's [[ShootTheBullet Interceptors]] faster than multiple [=EarthForce=] warships would be able to in other occasions, but once you manage to hit them they go down quickly.
* ''Series/AgentsOfSHIELD'' has most of the Inhumans, at least the ones relevant to the series. Most of them only gain one power, and while that power tends to be ''very'' useful, they generally lack anything else to protect them. In particular, the series' lead Daisy Johnson has a power that is comparable to the Hulk in terms of damage she can dish out, but excessive use of it can injure her and beyond that she's a rather short woman who, while exceptionally combat trained and more resilient than most, can still be overpowered and outmatched by stronger combatants or numbers. As a result of this, he Inhumans that avoid this status, such as Hive and Lash (who both have a ''very'' wide array of powers that include super-fast healing factors and/or invulnerability), are treated as pants-shittingly terrifying as a result, while Joey, who's power to control matter makes him both bullet proof (bullets just melt) ''and'' useful in combat situations, is a StoryBreakerPower who got PutOnTheBus to avoid him being able to solve most problems.

* The ''Runepunk'' podcast series from Podcast/{{RPGMP3}} features a character called Kieron Hammerfall, an [[OurElvesAreBetter Andari]] [[InstantRunes Rune]][[SquishyWizard caster]]. Kieron is imbued with [[LinearWarriorsQuadraticWizards momentous arcane power]], as well as the durability of a dry twig.

[[folder:Professional Wrestling]]
* Wrestling/MasakatsuFunaki in both pro wrestling and mixed martial arts, the latter even more so. Susceptible to take downs and no chin, he relied on simply submitting you before you hit him.
* Wrestling/KevinNash, big guy around seven feet tall, likes to brag about how badass he is, tears his quadriceps by stepping through ring ropes.
* Many power wrestlers tend to be injury prone, such as Wrestling/MarkHenry and [[Wrestling/DavidHeath Gangrel]] and [[Wrestling/CarleneMoore Jazz]]. Wrestling/{{Batista}}'s case was lampshaded by Wrestling/TripleH, who teased an Wrestling/{{Evolution}} reunion to deal with Legacy, only to reject the idea because Randy was a jerk and Dave was always hurt. It was also lampshaded by Wrestling/AJStyles in a wonderful TakeThat.
-->'''AJ''': ''(in response to Dave calling him a SpotMonkey)'' I think it's funny that a guy who takes a bump and tears his back tells me I don't know how to wrestle.
* Wrestling/MinoruSuzuki was an example of a mixed martial artist, who in turn went back to pro wrestling as his injuries started to rack up. He was solid in taking down people and submitting him, but some hits were enough to stop him.
* Many "high flier" wrestlers such as [[Wrestling/EvanBourne Matt Sydal]], who showed these tendencies right out of Gateway Championship Wrestling, are also this trope, the commentators actually yelling at him for doing a cannon ball off a balcony after returning from injury. Wrestling/{{Mistico}} became one when he went to Wrestling/{{WWE}} and was repackaged as "Wrestling/SinCara".
* Wrestling/CMPunk is a downplayed example, as his famous hour long matches and {{Garbage|wrestler}} matches make it hard to view him as "fragile" but he's one of the few wrestlers who will actually [[TheatricsOfPain sell]] for the notoriously non athletic Wrestling/PaulHeyman. Punk has only "sold" when Heyman was wielding a weapon, but Wrestling/{{Madusa}} and Wrestling/ChrisBenoit wouldn't even do that much. Punk can hoist wrestlers like Wrestling/{{Raven}} and Wrestling/SamoaJoe up, if they get careless, and knocked the likes of BJ Whimter and Wrestling/AlbertoDelRio unconscious, so he could presumably harm Heyman much worse than Heyman could harm him.
* Wrestling/{{WSU}} has many examples, such as The Human Tornado (before they became an All Women's fed in 2007), Marti Belle (large spirit, small frame), The Fly Girls (Niya's really strong anyway but both tend to get tossed around simply because they're so short), the [[Wrestling/AJLee A]]C Express (great at countering moves, tend to be gone as soon as they don't).
* [[Wrestling/GailKim The Queen Of Cats La Felina]] in the Apocalypse Wrestling Federation. Able to go entire matches taking virtually no offense from opponents only to lose in the end.
* [[Wrestling/BlackRose La Rosa Negra]]'s self appointed bodyguard Noemi Bosques. One the top ten bantam weight boxers in the world, top three in the country, most of Rosa's would be assailants shrink away from her fist and those that don't get floored. Boxing bantam weight's 110-118lbs, making [[FanNickname NONO]] noticeably smaller than her charge and quickly brushed aside by the few who managed to get her before she could land a punch.
* Manny Ferno in Puerto Rican EWO. Perhaps the best spear in the business("una lanza incredible!"), but he's much smaller than most men who use the move, to the point one of his other moves, which involves putting his weight on the back of his opponent's neck, has seen him flung skywards.
* Part of the reason why Wrestling/AshleyMassaro's momentum was killed in WWE. She only wrestled for three years, yet suffered about as many injuries as someone who had been wrestling for ten.
* Wrestling/{{Layla}} also became very injury prone in her final years.

[[folder:Tabletop Games]]
* There is an old (board and miniatures) gaming expression called the ''fuzzy wuzzy fallacy'' (after the Creator/RudyardKipling poem). Basically it states that a unit's effectiveness goes up proportionate to the square root of any increase in firepower (provided the defense stays the same). For example, the above Mech has roughly 3.5 times the firepower of the old version. FW numbers say that it's about 1.87 (the root of 3.5) times as effective as the old one, given that both die just as easy (and will draw fire like no-one's business).
** [[http://arxiv.org/abs/math.HO/0606300 The model behind it]].
** [[http://en.wikipedia.org/wiki/Lanchester%27s_laws For laypersons.]]
* In the Flying Frog game ''Touch of Evil,'' the schoolteacher only has three hit points and no healing factor. However, loading her inventory up with books adds two additional fight dice per book. Collecting all the books on the board gives her three hit points...and up to ''twenty-two'' dice's worth of damage. By the game's mechanics, [[DidYouJustPunchOutCthulhu that's theoretically enough to one-shot Cthulhu.]]
* The Eldar and Dark Eldar of ''TabletopGame/{{Warhammer 40000}}'' often overlap this with FragileSpeedster.
** The Dark Eldar are more of Glass Cannons than the Eldar, given the amount of firepower that squads of Dark Eldar can pump out for a relatively low cost and the eschewing of even what little armor their cousins use.
*** Harlequins are even more of a glass hammer/cannon than other Eldar. Absolutely unparalleled in hand-to-hand combat, they can rip right through a unit of Assault Terminators like tissue paper; but one good round of shooting from a basic Marine squad and they're splattered all over the landscape.
** The SpaceMarine Thunderfire cannon. In fact, ''all'' artillery pieces were like this prior to 6th edition. As an artillery piece, anything shooting at it has a 50/50 chance of hitting either it or the Techmarine manning it. Hitting the Tech is not a huge issue, with a 2+ armor save, but if the cannon itself is hit, either a penetrating hit or glancing hit will completely destroy it (until 6th edition, when artillery guns were given a very strong Toughness value of 7 and two "wound points"). But it has a range of 60', and puts out four explosive shells per turn.
** And Tau Fire Warriors, who are no tougher than Guard Stormtroopers and suck in close combat. However, they're armed with a gun that will punch through Stormtrooper armor, the Stormtrooper wearing the armor, and keep going out the back.
*** Speaking of Stormtroopers, their hellguns can punch right through SpaceMarine armor. Too bad for the shorter than normal range.
** The Tau's Vespid allies overlap this with FragileSpeedster. They have a gun that can blast clean through Space Marine armor from 18" away, and can move reasonably quickly, but even with T4 and a 4+ armor save, they still go down like chumps to even a brief encounter with heavy bolter fire.
** Ork Boyz: they have a massive amount of attacks for a rank-and-file trooper (three attacks per Boy, four on the charge), and... paper thin armor. Kinda balanced out by their ridiculously low point cost, but when they get showered by bolter fire, expect a lot of Boyz to drop.
** Daemons also deserve a mention -- most of them pack a punch, but die like flies against standard Imperial weaponry because their [[RealityWarper "armor"]] is intentionally designed to be fickle. They have a 33% chance of surviving ''anti-starship weapons'', but a 67% chance of dying to a single small-arms round to the face.
** The Imperial Guard Hellhound. Most Imperial Guard vehicles are MightyGlacier, but the Hellhound, for all the flamethrowers it mounts, can go up with a mild hit due to the tanks being hit.
** The ''TabletopGame/RogueTrader'' rulebook specifically describes Raider-class spacecraft as "glass cannons, able to throw out heavy fire but unable to take it in return".
** Eldar and Dark Eldar spacecraft in ''TabletopGame/BattlefleetGothic'' have wimpy armor, no shields, ridiculously powerful engines, and some of the nastiest guns possible.
** Most walkers, due to them having medium to light armor all around, as opposed to the incredibly tough front armor and weaker side and back armors of conventional tanks. The Penitent Engine and Ork Killa Kans in particular have it bad, as their armor is no better than the lightest transports in the game (the Penitent Engine is an open topped vehicle too). The only aversion so far is the Soul Grinder, which has near land-raider levels of armor while packing very effective guns and devastating melee capability (its only real weakness is everything else in the army tends to suck).
** Imperial and Renegade Knights are devastating weapon platforms capable of wielding rapid-fire battle cannons and [[MoreDakka massive gatling guns]] simultaneously. However, they only have an armour value of about 13 and their ion shield can only protect one facing at a time. On top of this, the absolute cheapest Knight is about 325pts and only has six hull points, about twice that of the much tinier Space Marine Dreadnought; the kitted-out ones can close in on 500 points, still with only six hull.
** The Chaos Forgefiend with three ectoplasma cannons is capable of tearing through heavily armoured elite forces in seconds - its blasts can disintegrate entire squads of Grey Knight Terminators. However, those same cannons are prone to overheating and damaging its hull, which is comparatively fragile at 3 Hull Points for a 200 point unit.
* The ''TabletopGame/{{Battletech}}'' universe:
** The ''Hunchback [=IIc=]'' [=BattleMech=] exemplifies this trope. It mounts two Ultra Autocannon-20s which, more or less, is apocalyptic firepower for any 'Mech (''each'' Ultra AC can do 40 damage, which will destroy any mech its weight or less with a center hit), but sacrifices almost all of its armor in order to do so. Little wonder it's popular with DeathSeeker Mechwarriors. In fact, a recent {{sourcebook}} clarifies: It was made as pretty much the Clan's equivalent of a Death sentence. Any warrior assigned to a ''Hunchback [=IIc=]'' is explicitly ''not'' expected to come back from their next battle.
** In the same vein, the dinky ''[=UrbanMech=]'' mounts an AC/10, but has only 6 tons of armor--appreciable for its size of 30 tons, but still not very much. However, any light mech ''will'' be cored if Urbie hits it, and more than one Urbie makes things get very dangerous in a hurry unless you outrange them. Plus they're such ''cute'' little things!
** See also the ''Hollander'' family. The original was a 35-tonner packing a mighty Gauss Rifle... and only that. With only four tons of armor for protection, it can barely take a hit from its own weapon. Other variants tried to mitigate this with limited success, but a few actually doubled down on it. One variant of the 45-ton ''Hollander II'' carried a ''Heavy'' Gauss Rifle, but had so little armor it stood a chance of ''killing itself'' every time it fired[[note]]Firing a Heavy Gauss Rifle required a piloting roll to keep from falling down. As a medium mech, the Hollander II has a penalty for that roll. Worse, the mech's rear armor was insufficient to take the impact of its own weight, so falling was an automatic critical hit. If it fell on the left torso(best-case scenario), it lost a ton of ammunition. If it fell on the center torso, it damaged its engine or gyro, and if it fell on the right torso, the Gauss Rifle takes the hit and explodes with just enough force to destroy both the Right and Center torsos, thus wrecking the mech.[[/note]].
** A lot of "support" 'mechs, like the classic ''Catapult'' or the frankly ridonkulous-looking ''Yeoman'', will mount a lot of long range weapons like [=LRMs=], but have little armor or weapons for close-and-dirty combat.
** There are a few vehicles like this, such as the ''Hetzer'' Wheeled Assault Gun, effectively a rehash of a ''World War II'' design, and the tiny 5-ton ''Savannah Master'' - the fact that it was deliberately designed to take on enemy Battlemechs has to count for ''something.'' Neither design has much armor, but both have a lot of firepower for their size. The ''Savannah Master'' has the firepower and speed to equal to a 'Mech four times its size, but can be destroyed by a single laser hit from its own gun. Meanwhile, the ''Hetzer'' is larger and slower, but mounts a huge, dangerous [[{{BFG}} 200 millimeter autocannon]] in its hull that has a chance to bring down even the mightiest of 'Mechs with a single hit--without giving it more than a token amount of armor to cover its fragile, boxy hull.
** In the novels particularly, the old Inner Sphere ''Rifleman'' 'mech is notorious as a deathtrap, with rear armor somewhere between cardboard and tin can levels. You don't want to be standing in front of it, though - [[GunsAkimbo each arm mounts]] an autocannon and [[FrickinLaserBeams medium and large lasers]].
** The ''Hellbringer'' (''[[ReportingName Loki]]'') Omni is another fine example of a machine that will slaughter most enemies in its weight class and down if they get too close, but will crumple and burn if anything with a decent gun looks at it funny. Its configurations focus on massed long range hitting power, with things like particle cannons, Gauss rifles, and autocannons coming into play. The primary variant is a highly accurate killing machine with enough firepower on it to literally slag four tons of armor in a single salvo and even includes various equipment upgrades like ECM or anti missile defenses. At 65 tons and with only 8 tons of armor, though, it'll have an extremely bad day if a sufficiently armed 'Mech draws a bead on it. It's so light on armor that it actually can't even absorb an AC/20 shot dead center--something that more than a few 15-tons-lighter 'Mechs ''can'' do.
** The ''Adder/Puma'' is another high grade glass cannon. Its primary configuration carries dual ER-PPC weapons and includes a targeting computer to make them highly accurate. Any 'Mech who takes a BoomHeadshot from one of those guns is down for the count, no matter the size of it. The Adder, however, is all of 35 tons, has about 6 tons of armor, and generally isn't going to stick around very long once an enemy sniffs it out.
** The ''Cougar'' is, if anything, even more extreme than the ''Adder''. While weighing the same 35 tons, its armor is pared down to just five and a half tons, and its speed is further cut to levels more often seen on Clan 'Mechs twice its size, making it less capable of dodging attacks. In exchange, it now boasts a full ninteen tons of firepower, meaning that over 50% of this thing is guns. Its basic configuration carries two highly accurate long-ranged lasers and a pair of long range missile racks. One of its alternate models matches the ''Adder'' exactly for deadliness with its dual PPC loadout, while another is a perfect copy of the ''Archer,'' a highly respected Inner Sphere 'Mech that is twice the size of a ''Cougar''.
** The ''Hollander'' is a classic example, being sluggish, lightly armored, and inherently fragile--it weighs 35 tons, carries a mere 4 tons of armor, and one side of its torso is packed full of volatile, explosive capacitors. It's so fragile that a large laser hit to any body part is enough to seriously threaten its continued existence. However, those same capacitors power a 15-ton [[MagneticWeapons Gauss rifle]], which packs enough kinetic energy to bore a hole straight through smaller 'Mechs or smash a ton of armor off bigger ones, and SnipingTheCockpit is a OneHitKill on any 'Mech.
** The ''Excalibur'' is a mighty-looking machine and boasts both a Gauss rifle and a [[MacrossMissileMassacre long range missile pack]] in its primary configuration. It even moves at a healthy 86 kph, impressive for a 70-ton 'Mech. It buys that mobility and long-range prowess with a woefully thin seven and a half tons of armor, enough to weather one or two light missile barrages, but not enough to survive repeated fire from bigger guns like a PPC or a 100mm autocannon.
** There's a variant of the ''Shadow Hawk'' that adds a second short range missile launcher, a second medium laser, and two more heat sinks to its chassis. This changes the ''Shadow Hawk'' from a mediocre MasterOfNone into a respectable barrage vehicle at short range--it can leap into battle and unload all its weapons without too much stress on the heat gauge. The problem is that it buys this firepower in armor, reducing it to an anemic 4.5 tons of armor, less that some 'Mechs half its size... and it still carries four tons of highly volatile missile and autocannon ammunition in its chest, so one unlucky hit could lead to a lot of StuffBlowingUp.
* ''TabletopGame/DungeonsAndDragons 4E'' gives us the Striker set of classes (Ranger, Rogue, Warlock, Barbarian, though the Barbarian has pretty good HP, if lackluster starting armor): Insane damage output, but rely on the [[KnightInShiningArmor Defenders]] to hold down the thing they're attacking so that they don't get crushed.
** 3.5 psionics has the wilder class. Less than a fourth of the powers of a Psion, but can up each powers output by your level, turning a single level 3 character into something capable of cutting down much higher level enemies on average rolls. Has little health and can daze/weaken themselves afterward. Unfortunately, the downsides add up to make it AwesomeButImpractical.
** [[MinMaxing Some 3.5 characters, using a number of different sourcebooks,]] can become this trope. As an example, take an ordinary fighter and give him Power Attack, a feat which subtracts attack accuracy in exchange for higher damage. Then take a feat called Shock Trooper, which shifts the accuracy penalty to armor class -- i.e. it makes you easier to hit. This build, known as the 'Charger build' and often ''by'' the name Glass Cannon, results in a character able to do massive damage when he charges in and attacks ... but at the cost of an armor class that a small child throwing rocks could probably hit.
** 3.5 Rangers fit this trope: A melee-focus Ranger with Weapon Finesse(allowing the dex-focused Ranger to use dexterity for attack accuracy instead of strength, and in some cases, generally House Rule, for damage as well) and a rapier-shortsword combo can cut through quite a few opponents at or even slightly above his/her challenge rating. The trade-off is that to use the Ranger's Combat Style, which is what grants free Two Weapon Fighting feats or Ranged feats depending on choice, the Ranger can only wear light or no armor, giving him/her a low AC that most enemies can punch through with no problem. This is slightly compensated for by their high hit dice(a d8, instead of the d6 of Rogues or the d4 of spellcaster classes), which is still smaller than that of fighters and Paladins. The only way to get a higher AC, meanwhile, is to invest a lot of gold into mithril armors(which makes Medium armors into Light armors) or a shirt of Millennial Chainmail from Complete Divine, which is exorbitantly expensive but allows for a whopping +8 Dex-to-AC.
** Duskblades utilize a nasty form of FullContactMagic that can reduce most level-appropriate foes to dust, but possess virtually no defensive spells, middling HD, and similar armor restrictions to the Ranger.
* There are plenty of ''TabletopGame/MagicTheGathering'' cards that have high power but low toughness. However, the card [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=83719 Glass Golem]] seems to deliberately invoke this trope.
** Not to mention cards like [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=1133 Rocket Launcher]] and its later cleaned-up cousin [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=48215 Goblin Cannon]], which take the "cannon" part more literally.
** Also, a number of Illusion creatures are designed to hit hard, but die as soon as targeted by anything.
** [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=130713 Force of Savagery]] is another extreme example. It has massive power but ''zero'' toughness so it automatically dies when it enters the battlefield unless its toughness is being passively boosted.
** Perhaps the most extreme example lies with [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=368981 Master of Cruelties]]. It has a moderate Toughness of 4, and a mediocre Power of 1, and can only attack alone without backup. However, it also packs First Strike and Death Touch, thus becoming instant death to any creature that blocks it. Even worse, if its attack connects without being blocked, the unfortunate player's life total '''instantly drops to 1'''.
* Between the five colors, red is the one that most exhibits this trope. Most mono-red creatures tend to have very low toughness, but higher power. Since red is more about dealing as much damage to its opponent as quickly as possible, its creatures don't need to survive, just take a few cheap shots in.
* [[HandsomeLech Carefree Hedonist]] characters in ''TabletopGame/BlissStage'' start out with 7 instead of 6 relationships, most of which have very high Intimacy [[RelationshipValues and form very powerful psychic weapons]]. Only TWO of those relationships have enough Trust for the weapons they manifest as to survive a critical failure.
* There are various ''TableTopGame/YuGiOh'' cards like: Goblin Attack Force, Indomitable Fighter Lei Lei, Spear Dragon, and Mad Archfiend that have incredibly high ATK, but zero DEF and move into defense position when it is time for your opponent to strike.
** Clear Vice Dragon has double the ATK of the monster it's attacking. When it's not attacking, it has 0 ATK.
** Similarly, Metalmorph gives the equipped card a massive attack boost, but only while attacking.
** Dragon Master Knight has a titanic ATK stat and an effect that makes it stronger, but it has no defenses whatsoever from card effects.
*** This was the standard design philosophy for an ace card until Stardust Dragon showed up: a card with 2800 ATK or more, with an effect that lets it kill even more monsters and do even more damage than its ATK score would suggest, and no protection or negation abilities whatsoever. The most infamous examples should probably be the Chaos monsters, which can easily knock off half your opponent's LP in a single turn on their own, but fold like a wet paper bag to a garden-variety Bottomless Trap Hole or Sakuretsu Armor.
** Berserk Dragon has 3500 ATK and 0 DEF, which would already qualify it for this trope. However, it goes the extra mile, with an insanely strong offensive effect (can attack all cards your opponent controls) and a tendency to fold quickly if it doesn't knock out the opponent in one shot, due to growing weaker every turn it's on the field.
** Armityle the Chaos Phantasm is the biggest example in the franchise. When it's attacking, it has 10,000 ATK; the highest fixed number in the entire game, and twice as high as the highest-ATK monster in the game. When it's not attacking, it has ''zero'' - and on top of that, it can't be destroyed by battle, meaning the opponent can keep attacking it over and over as if they were hitting you directly.
* ''TabletopGame/{{Warhammer Fantasy|Roleplay}}'' has a few. Night Goblin Fanatics follow it the best -- they deal the same damage as a giant catapult but are even easier to kill than a normal goblin and have a chance of killing themselves. There are, however, many others.
%% ** All varieties of [[OurElvesAreBetter elves]] have most of their units as Glass Cannons.
** Wood Elves are similar to 40K's Eldar, being both this and {{Fragile Speedster}}s. They have little to no armor but can give out a lot of hurt with possibly the best core units compared to their prices.
** High Elves have very few units with toughness higher than 3, but they make up for it with ''Speed of Asuryan'', gaining attack bonuses if their Initiative score is higher... and at 5 initiative on most of them, it usually is. This rule also ignores striking order penalties for weapons, so they can wield [[{{BFS}} whopping weapons]] [[AddedAlliterativeAppeal willy-nilly]] at no penalty.
* ''TabletopGame/StarFleetBattles'' has:
** Fast Patrol Ships (formerly known as Pseudo-Fighters). They can carry devastating armament, but their shields are paper-thin. The rules even refer to them as "eggshells armed with sledgehammers." [=PFs=] with Warp Booster Packs gain extra warp-engine power, which they can [[TimTaylorTechnology pump into their weapons for an even bigger punch]], but are even ''more'' vulnerable to enemy fire.
* This is the modus operandi of the Norse team in ''TabletopGame/BloodBowl''. Catchers/Runners get Dauntless to take down opponents far above their own weight class and Blitzers/Berserkers are ExactlyWhatItSaysOnTheTin. However, every single human team member starts with an Armor Value of 7...the same as a regular goblin. This makes AttackAttackAttack actually a viable strategy for them since they absolutely need to maintain the initiative. If the momentum shifts against them the entire team quickly turns into messy stains on the astrogranite...
* Coinshots in ''[[TabletopGame/MistbornTheOriginalTrilogy Mistborn Adventure Game]]''. Just like in the source material, these guys can essentially become human machine-guns, but they have no defensive powers and inferior Health when compared to an unpowered character.
* Dark Pokémon in the ''[[TabletopGame/{{Pokemon}} Pokémon Trading Card Game]]'', when introduced, had very low HP but either high damage, low Energy requirements, or useful effects. This trait was cast aside in "EX Team Rocket Returns," however, as the Dark Pokémon in that set were just as hardy as anything else. Nevertheless, there are still a few specific species of Pokémon whose HP are lower than other fully evolved Pokémon from their sets but make up for it with other means, such as Raticate, Delcatty, Castform, and Durant.
* The ''Zealous'' in ''[[TabletopGame/FleetsThePleiadConflict Fleets: The Pleiad Conflict]]'' has only six health and can't support many consorts, but it not only has eight strength, but its special ability allows it to attack twice, for a whopping ''sixteen'' strength attack.
* Many of the aircraft carriers in ''TabletopGame/VictoryInThePacific'' are this, with low armor factors and airstrike with a bonus die-roll modifier representing the highly-trained pilots, but most notable is the Japanese carrier ''Hiryu'', the sole fleet carrier with an armor factor of only 1.
* ''TabletopGame/LegendSystem'': The Sage and Shaman classes. Courtesy of their numerous and powerful spell-like abilities, Sages can put out a lot of pain from both close-up and at a distance, on top of their considerable crowd-control and support options, but a poor BAB combined with NoSelfBuffs means they're rather fragile if an enemy actually manages to get through the onslaught. Shamans, meanwhile, can inflict staggeringly high single-target damage via their Imbue Spell ability, but suffer from many of the same durability problems as the Sage. ''Legend'' being what it is, both of these classes can become less squishy (or ''more'' in exchange for more power) via multiclassing.
* ''TabletopGame/StarWarsBattlefront'': Han Solo is a glass cannon. He carries his most powerful pistol in the galaxy the DL-44 Blaster Pistol. He can overpower his enemies in great distances. He has three outstanding output ablitites: 1) Rapid Fire: A long range ability to let him rapidly fire repeatedly without over heating against group of enemies. 2) Lucky Shot: A long ranged charge up blaster so powerful it can break Darth Vader lightsaber blocks and it can lock on soldiers and vehicles. It can lock and take out a group of Imperial starfighters in a single shot. 3) Shoulder Charge: A short-ranged ability let Han Solo to lower his shoulder into his enemy to apply damage. It only works in line of sight. Han Solo defense is terrible. His hit points will drop faster than you can say "Oh S***!" He can't handle in a melee. He is doomed if surrounded by a group of Imperial soldiers and Galactic Heroes. The only way to avoid short melee is activate shoulder charge for a great escape.
* ''TabletopGame/Wizard101'': Storm wizards in wizard 101 has tremendous single and area of effect attack spells. But their hp and defense is terribly low.
* In ''TabletopGame/XWingMiniatures'', the TIE Phantom has a ''massive'' four-die main attack, the ''only'' ship in its size class with such a statistic, and can take the potent Crew and System upgrades. On the other hand, when uncloaked, it is no more durable than a humble Z-95 that costs considerably less. The dominant Phantom build, when Phantoms are run at all, is specced around getting to a high Pilot skill, taking an upgrade that lets you cloak after attacking, and praying that you get initiative so you can get that precious +2 Agility to make you die slightly slower.
* In ''TabletopGame/SentinelsOfTheMultiverse'', several of the heroes have low HP and low or action-intensive damage resistance, but can dish out staggering amounts of damage. Chrono-Ranger (whose damage with Hunter and Hunted goes up as he takes more bounties...but the damage he takes goes up at the same time) and Absolute Zero (whose playstyle is built around modifying the effects of punching himself in the face) are particularly notable, as is the Wraith (no natural damage resistance outside her base set version's power, but an array of incredibly destructive or inconvenient weapon attacks).

* Webcomic/{{XRS}} Despite its vaunted capabilities, the XRS is extremely vulnerable when its energy shields are down.
* Coffinshaker from ''Webcomic/WhatsShakin'' is a fairly powerful fire mage, but without his reliance of fire, is mostly vulnerable to all other attacks.
* ''Webcomic/EightBitTheater'''s Black Mage [[http://www.nuklearpower.com/2008/04/10/episode-977-moving-as-hell/ described]] himself in these words, a few days after this page was launched.
* The titular Webcomic/DominicDeegan shares a handful of qualities with Creator/MarvelComics' telepaths, i.e. physically weak while mentally untouchable. He describes himself as his body being "frail and weak, but [his] mind is a fortress you have no hope of conquering."
* In ''Webcomic/SluggyFreelance'', Torg is capable of killing just about anything when his CoolSword Chaz is powered up and [[PowerGlows starts glowing]]. While his sword is unbreakable and nearly unstoppable, however, Torg himself is as physically vulnerable as your average human being. It doesn't help that the sword's true potential can only be unleashed when it's [[PoweredByAForsakenChild fueled by the blood of the innocent]], a cost Torg is understandably reluctant to pay.
* Vaarsuvius from ''Webcomic/TheOrderOfTheStick'' fits this trope. As with Black Mage, (s)he falls pretty squarely in SquishyWizard territory.
%% * In the webcomic ''Caaats'', [[http://www.caaats.com/wp-content/gallery/strips/caaats19.jpg this scene.]]
* In Webcomic/{{Suppression}}, Charlie is a [[ShockAndAwe electricity-wielder]] who was kidnapped by the villains so that he could ''power their entire facility''. He can give off enough electricity to blow off [[BigBad Maxwell]]'s arm. He is also skinny as a rail and has neither armor nor the ability to take a hit.
* Fairies and tiny elves in ''Webcomic/FairyDust'' are quite deadly, but can be crushed by a larger humanoid's hand in a mere swat.
* [[PlayingWithATrope Played with]] with the titular ''Webcomic/KidRadd''. On the offensive side, his Mega Radd is technically only able to charge enough to deal 255 damage within his own game, but thanks to sloppy programming, there's actually no preset upper limit, meaning it's as powerful as the number of bits in the console he's on. When he's out on the internet, its power is effectively limitless, making him potentially strong enough to destroy the entire internet. On the defensive side, he can only take four hits before dying, but it doesn't matter what hits him. Getting hit with a nuclear bomb does the same amount of damage as having a {{Mook|s}} [[CollisionDamage walk into him.]]
* This is the case with [[spoiler:Gralo]], the BigBad of ''Webcomic/TheNightTheMagicDied''. While immensely powerful and capable of [[spoiler:causing a universe wide extinction on his own, he's]] only protected by [[spoiler:being able to [[ManaDrain eat any magic sent his way]] to a WalkingWasteland level]] and isn't exceptionally durable without it. Once that's bypassed, [[spoiler:he]] is easily wounded and [[spoiler:easily defeated by the Princesses]].
* Ran Cossack from ''Webcomic/BobAndGeorge'' is an {{exaggerated|Trope}} version. His Cossack Buster is the most powerful weapon in the comic amongst the various robots, but [[OneHitPointWonder even a slight breeze can kill him]]. [[TheyKilledKennyAgain Death only annoys Ran, however]]; he has a BodyBackupDrive at home, complete with teleporter to return him to the place he was last alive.

* ''{{Literature/Worm}}'':
** Besides enhanced timing and perception, Flechette has no defensive abilities. She has, however, demonstrated the ability to [[spoiler:cancel the Siberian projection]], which no other cape in history has managed to do. She was also able to [[spoiler:kill a cloned Grey Boy]] which had only been done previously by one of the most powerful characters in the story.
** Shatterbird takes the trope to literal levels, as she is able to cause glass in a city-wide radius to explode. This makes her one of the most devastating members of the Slaughterhouse 9, but she is also one of the most vulnerable.


[[folder:Western Animation]]
* ''WesternAnimation/TransformersAnimated'':
** Soundwave can easily take on multiple Autobots at the same time with ThePowerOfRock, has a massive number of various gadgets, and can control machines, but he's made of Earth machines mashed together, which means that even Sari's little hand-blast can put a hole in his shoulder, and when he is forced into melee combat, he is smashed apart in single blows. This contrasts with normal Decepticons, which are both figuratively and literally MadeOfIron.
** Swindle. As a result of his arms dealing he has some of the most impressive weapons in the universe, but is the only Decepticon in the whole show that Bumblebee's stingers have ever been effective against.
* Typical firebenders in ''WesternAnimation/AvatarTheLastAirbender'' have no special defensive abilities whatsoever. The only known modern defensive firebending technique was invented by Iroh by studying waterbending for inspiration and is very situational (only useful against other firebenders), with the ancient defensive moves of the Dragon Dance having been long lost (to most). However, they are capable of laying waste on a scale the other bending disciplines are incapable of.
* [[spoiler:Eddy's Brother]] from ''WesternAnimation/EdEddNEddy''. WordOfGod has gone on the record as saying that [[spoiler:unlike Eddy, who's had pain dished out to him but has built up more of a resistance to it, Eddy's Brother had been dishing ''out'' pain all his life, but had never been on the receiving end of it, and thus has a very low pain threshold]].
* In the classic WesternAnimation/DonaldDuck short "Canvas Back Duck", Donald ends up in a boxing match against [[NonIndicativeName Pee-Wee Pete]], and is only saved from a merciless pummeling when he accidentally discovers Pete has a (literal) glass jaw.
* The assassin Curare from ''WesternAnimation/BatmanBeyond'' seems this way. She's a deadly combatant with a sword, incredibly fast and agile, and very hard to lay a glove on, but when Batman actually manages to do so, it seems to hurt her badly.

[[folder:Real Life]]
* Since the introduction of gunpowder in the High Middle Ages, artillery is (probably) the very first and oldest definition of this trope: deadly when given a chance to attack from a safe distance but easily neutralized by the destruction of its crew and/or the cannon itself.
* Most anti-tank weapons teams count as this. Whether armed with an anti-tank rifle, manning an anti-tank gun, or carrying around a guided missile launcher, they have the power to potentially destroy an enemy tank before it gets the chance to destroy them. However, they lack any protection other than their firearms, and the sheer bulk of their weaponry limits their mobility, making them easy targets if detected.
* Tank destroyers. Popular back in UsefulNotes/{{W|orldWarII}}W2, they were ExactlyWhatItSaysOnTheTin -- usually armed with a tank-grade {{BFG}} to destroy enemy vehicles with great efficiency, using the element of surprise. However, their limitations compared to regular tanks (lack of armour, a gun with limited traverse, or both) make them vulnerable to a well-coordinated counterattack. In modern warfare, the role of tank destroyer has been taken up by [[DeathFromAbove helicopter gunships]], though a number of lighter vehicles have been adapted to the purpose as well.
** Modern wheeled tank destroyers are armed with large calibre guns and very mobile, though lacking in armour. [[JustifiedTrope They're not supposed to take on enemy tanks unless necessary]], as their main missions are tactical reconnaissance and fire support.
** American tank destroyers during UsefulNotes/WorldWarII in particular were ''very'' lightly armored, in most cases lacking a roof for their turret which exposed the crew to all kinds of nastiness. They usually mounted a relatively powerful anti-tank gun in a fully-traversing turret and were [[FragileSpeedster extremely fast]]: the [[http://en.wikipedia.org/wiki/M18_Hellcat M18 Hellcat]] can clock up to 55 mph on good roads. (That's 88 km/h for the rest of the world.) Conversely, M36 Jackson sported a 90 mm M3 cannon, which was able to defeat ''any'' German armour at ''any'' distance. [[LongRunner Last Jacksons]] participated in the Yugoslavian Wars of Disintegration and were finally phased out in 2002.
** Though the German and Soviet tank destroyers tended to go in the opposite direction, with [[MightyGlacier heavy armour and powerful guns with limited traverse]], they also produced a large number of lightly-armoured, open-topped self-propelled guns which were often used to take out enemy armour. In the case of Germany, some of these were specifically designed and pressed into service as tank destroyers, following their encounters with superior Soviet armour.
* The Swedish UsefulNotes/ThirtyYearsWar era [[http://en.wikipedia.org/wiki/Leather_cannon Leather Cannon]]. It was basically a copper barrel wrapped on stout leather, like cow hide. The idea was to make the cannon light enough to be [[FragileSpeedster mobile]] and easily carried, which it was. It weighed 40 kg (90 lb) and could easily be carried by two men. Unfortunately it also was prone on over-heating--leather is a good heat insulator--and tended to burst if three or more shots were shot in succession without letting the barrel cool down a bit. Purely as a weapon it was a failure, but as a concept it revolutionized the role of the field artillery.
** This was excellently highlighted in an episode of ''Series/MythBusters'', where the cannon was recreated and fired. Their prototype replica cannon successfully damaged the targets, but broke on the first firing. They still considered it a successful recreation because the output of the cannon was comparable to a period iron cannon, and because of its historical reliability issues.
* Suicide bombers also tend to fall into this. They don't usually pack armor or a gun, but when they explode, you're in trouble.
* Aircraft carriers exist to operate aircraft. Anything not related to operating aircraft is usually considered unnecessary, as the embarked aircraft give the carrier the effective ability to spot and engage enemy targets in a radius of several hundred miles or more. That they also tend to be [[MadeOfExplodium crammed full of munitions and volatile aviation fuel]] is just icing on the cake.
** Taken UpToEleven by Japanese WWII carriers, which had an enormous airplane capacity, but tended to ignite violently on two or three hits, largely because of poor damage control and internal design.
*** They attempted to rectify this with Taiho, with the design expected to remain able to operate after multiple bomb and torpedo hits. [[EpicFail A single American submarine-launched torpedo caused a fuel vapor explosion that sank her]].
** {{Inverted|Trope}} by the Royal Navy's armored carriers, which had limited plane capacity, but excellent anti-aircraft artillery and could take enormous punishment.
** Pretty much carriers can be seen too as the equivalent of a SquishyWizard particularly when they've run out of planes and/or ammo for them (read: the equivalent of spells), thus explaining why the equivalent of warriors (mosty notably battleships in WWII) must protect them.
* Light tanks by definition are supposed to be very mobile, primarily designed for scouting and exploiting breakthroughs in enemy lines, so they would often give up armour in exchange for greater speed and range. Although many fall under the FragileSpeedster category, several designs (particularly the American M24 Chaffee and M41 Bulldog, as well as the French AMX-13 series) qualify as Glass Cannons, having sufficient armament to tackle heavier armour.[[note]]A few designs, namely a number of WWII French tanks, would invert this completely by being relatively slow {{Stone Wall}}s.[[/note]] A good example would be the British "Crusader" cruiser tank: extremely fast and agile and armoured with the superb 6 pounder 57 mm cannon, which was able to knock out ''any'' German tanks at the desert, but itself vulnerable.
** The American M551 Sheridan (technically an "armoured reconnaissance/airborne assault vehicle") provides a remarkable example of this trope, being poorly armoured but armed with a low-velocity 152mm gun. Put into context, its shells packed almost as much explosive as heavy artillery shells. It could also fire anti-tank missiles, which could theoretically take out any contemporary battle tank, though these were almost never used.
** The Soviet BT-series tanks were among the fastest tank designs of WWII, but were also fairly well-armed for their time with a high-velocity 45mm gun. They could reach speeds of up to 72 km/h on good roads, and had good range to boot. They were however, poorly armored: they could only protect their crews against regular rifle fire and nothing else.
*** In the 1930's, the Soviet Union experimented with mounting rockets on tanks, producing [[http://epizodsspace.airbase.ru/bibl/shirokorad/ot-min/244.jpg this monstrosity]]. Due to several defects with the design (namely horrifying lack of accuracy), it was never put into production.
* Main Battle Tank design took something of a detour in this direction during the 1960s, at least in Western Europe. Confronted with widespread HEAT weapons, against which steel armor required prohibitive thickness to stop, the designers of the French AMX-30 and German Leopard I dispensed with the heavy steel armor of many contemporaries in favor of greater mobility afforded by the lighter weight. Not that they were un-armored, mind you, but they were emphatically not designed to take hits from anything larger than autocannon and keep trucking. This detour ended in the 1970s with the development of composite and reactive armors, which could provide protection against HEAT weapons without prohibitive weight costs.
* Missile transporter-erector launchers are arguably the ultimate example of Glass Cannons in real life, being armed with a weapon that can wipe out a small town but completely lacking any means of self-defence. With that said, the concept inverts this in that the launchers are hard to track down and can relocate after firing.
* For much of their existence, submarines have proven to be exceptionally deadly against ships, utilizing their stealth to sneak up on surface vessels and sink them before the latter can react. However, if they are detected before they have a chance to fire, submarines pretty much lose the only advantage they have.
** Ballistic missile submarines take the concept to an extreme, in that they are armed with enough nuclear weapons to vaporize a small country, though are virtually incapable of defending themselves if detected.
* Torpedo boats were essentially [[ExactlyWhatItSaysOnTheTin small but inexpensive vessels armed with torpedoes]]. Theoretically capable of sinking larger warships, they in turn could be sunk by gunfire well before they could get in range.
* [[https://secure.wikimedia.org/wikipedia/en/wiki/Monitor_%28warship%29#World_War_I WWI style Monitors]] were shallow draft ships of questionable seaworthiness onto which the largest spare gun(s) at hand was crammed. Basically a floating artillery battery, they had the advantage of being cheap and able to get in very close to shore where traditional naval ships could not go, even going up rivers.
* Anything the Finnish Navy can throw in. Their ships are crammed with oversized guns and missiles, and outfitted with minelaying equipment, but have no armor whatsoever - they rather employ hiding in the archipelago as their defensive strategy. It helps that Finland has one of the most diabolical archipelagoes and littoral waters in the world. There is always a small island behind which you can hide.
* There was a period of time during The UsefulNotes/ColdWar when some tank designers believed that the growing power of anti-tank weapons would eventually make conventional heavy armour useless. To this end, France and West Germany began designing tanks with lighter armour to increase mobility, all the while maintaining their heavy guns.
* Humans are generally a race of Glass Cannons in that our technological ability to inflict damage is much greater than our technological ability to defend against damage. They had to build NORAD inside a small mountain to ''maybe'' protect it against nukes.
* Bob Sanders, safety in the NFL, long of the Indianapolis Colts. One of the league's hardest hitters, maybe the best safety in all of football... when he was healthy, which for a while was about as rare as the Colts beating the Chargers in those days (the latter is no longer rare for the Colts). Sanders frequently spent half the regular season on the injured list, which might be because he played so hard all the time, running full-force into offensive players on every play. The Colts finally released him after the 2010 season, and Sanders played one more (injury-shortened) season for the Chargers before being dropped for good.
** The Eagles' Michael Vick fits the archetype perfectly. With his freakish speed and arm strength, Vick is the single most dangerous playmaker in the league... as long as he doesn't get hit too hard. In 9 seasons, he's played all 16 games only once, and has spent quite a few contests limited due to one injury or another. Not counting the 2 seasons he missed while answering to "[[{{Prison}} Federal Inmate #33765-183]]".
** Quarterbacks in general. Quarterbacks can do punishing damage throwing the ball downfield and serve as the offense's field general. However, if the StoneWall offensive linemen screw up their blocking assignments, the quarterback usually doesn't have the strength or mobility to do anything except brace for impact and try not to get hurt by the 300+ pound men piling onto him. However, mobile quarterbacks like Dak Prescott or Deshaun Watson have the speed to evade defenders and take off running, and big guys like Ben Roethlisberger can fight through tackles to make a play.\\\
Quarterbacks are also the only players besides kickers and punters who are not obligated to consistently engage another player physically (whether via tackling/being tackled or blocking). Pretty much all teams forbid their players from hitting the quarterback during practice, and [=QBs=] are generally the only players on offense or defense who will slide to a stop in order to avoid being hit after picking up positive yardage.
* Baseball:
** One recent example is Washington Nationals ace pitcher Steven Strasburg. He has overpowering stuff which can strike out a lot of batters. Unfortunately, he keeps getting injured after he makes a couple of starts on the mound.
* Basketball:
** Enes Kanter of the Oklahoma City Thunder is one of the better offensive centers in the NBA. In the 2014-15 season, he averaged a solid 15.5 points per game. However, his defense is [[https://twitter.com/bball_ref/status/619246851263311872 historically poor]].
** James Harden is one of the best offensive players in the NBA, and his shooting skill has led to some branding him the best Shooting Guard in the NBA since Kobe Bryant retired. Unfortunately, his defense is [[https://www.youtube.com/watch?v=KMKavKEKX2Q memetically horrible]].
** UsefulNotes/StephenCurry is this, to a lesser extent. He's an [[ImprobableAimingSkills excellent shooter]] and a solid passer, but his defense is just mediocre to average. This is slightly mitigated by the fact that he has defensively skilled teammates (e.g. Draymond Green, Klay Thompson, Andre Iguodala) and that he actually ''tries'' to play defense; contrast that to Harden, who seems like he '''[[BrilliantButLazy doesn't even try]] to play defense!'''
* Several examples in mixed martial arts, including fighters that have devastating offense and a weak chin.
** Wrestling/BobSapp has enough strength to pick up a 260 pound man ''literally'' off the mat and [[http://i26.tinypic.com/2qk76ae.jpg piledrive]] him violently to the ground. Yes, in MMA, where piledrivers are neither safe nor done with compliance from the victim. He beat one of the best kickboxers in the world (Ernesto Hoost) ''twice'' in 2002. Sapp is also known for the trifecta of having a glass chin, possessing very little toughness or heart, and having laughably few grappling skills. He lost in 2009 to a man 150 pounds lighter than him who fancies himself a superhero, sports a mullet, and goes by the name "[[WidgetSeries Minowaman]]."
** Melvin Manhoef, a dutch kickboxer, has truly horrifying punching power. He was the first, and so far only man to ever knock out [[WildSamoan Mark Hunt]], who was famous for shrugging off career-ending strikes to his presumably [[MadeOfIron granite-filled head]]. Manhoef delivered [[http://i40.tinypic.com/14muw47.jpg said KO]] while ''[[ArtisticLicenseMartialArts moving backwards]].'' Unfortunately, even though he's fought at the highest levels of kickboxing and MMA and can put together beautiful offensive combinations, Manhoef's strike defense is quite lacking, and he has been knocked out by mid-level fighters far more often than an elite striker should. More saliently, his grappling skills are pure garbage. For MMA professionals, fighting Manhoef can either end in Melvin decapitating you with a punch, or with him meekly tapping out 15 seconds after the fight hits the mat.
** Many fighters like Melvin Guillard and Houston Alexander have decent striking, scary power and zero grappling skill. Stand with them and they're likely to hurt you, take them down and they'll play you the three-tap symphony.
** Alistair Overeem is widely regarded as one of the hardest hitters in an already hard-hitting UFC Heavyweight Division, and has also been the victim of some classic knockouts due to the fact that physically, he simply cannot absorb as much damage as other heavyweight mixed martial artists can. It's gotten to the point where Overeem will actually turn his back on his opponent and ''run away'' in the octagon if he feels overwhelmed[[note]]he's done this in two separate fights; vs. Stipe Miocic at UFC 203, and vs. Mark Hunt at UFC 209[[/note]], which is an extremely rare strategy in professional MMA, much less the UFC (the consensus highest-level MMA promotion).
* Boxing:
** Julian Jackson was a boxer whose career spanned the 80s and the early to mid 90s, and is boxing's patron saint of the one punch knockout. Being in the ring with Jackson was to always potentially be one punch away from being KO'd. However, some of Jackson's victims were only knocked out because they knew of the weakness in Jackson's own chin and tried to knock ''him'' out first. The most prominent example is probably Herol Graham, a [[StoneWall slick defensive specialist]] who made his living by dodging punches and countering his way to a decision. Graham was able to stun Jackson consistently in the first three rounds of their fight, so he pushed the action and had Jackson backing up in the 4th. Then Jackson connected with a single blow and not only was Graham unconscious before he hit the canvas, he remained out for minutes afterward. [[http://www.youtube.com/watch?v=QpbVYeqgROw Final round and aftermath of the Jackson-Graham fight]]. Several years later the difference between a hard puncher who can take a punch and one who cannot was shown when Jackson fought Gerald [=McClellan=], who was bigger, could hit as hard as Jackson if not harder, but could also take a lot of damage. [=McClellan=] promptly knocked Jackson out twice in their two fights, the second time coming in the first round.
*** Sadly, [=McClellan's=] career was ended, and he was left disabled for life, after his very next fight against Nigel Benn, another fighter widely perceived to be incredibly strong and hard hitting, but with an unreliable chin. On that particular night, however, Benn soaked up all the damage [=McClellan=] could dish out, (which was a '''''lot''''' of damage) and came back for more, until finally [=McClellan=] collapsed in the ring.
** Some would say that British heavyweight Frank Bruno was also a Glass Cannon. Bruno possessed a punch that could stop almost anything if landed properly, but had the weaknesses of being a bit slow and unwieldy. Ironically, Bruno didn't get accused of being a glass cannon because a single punch would knock him down or out, (being knocked down by the blows might have actually given him additional time to recover) but because being hit with a big shot tended to leave Bruno frozen in place, on his feet but stunned and momentarily defenseless, and the followup punches from his opponent would then inevitably finish the fight.
** Late in Mike Tyson's career and ''long'' after Tyson's prime, his old trainer Kevin Rooney who coached him at his best complained that Tyson was no longer the elusive LightningBruiser who had once dominated the boxing world. "His style was to use head movement, be elusive. He's not using the style the way he's supposed to be. He's just... he's just a puncher now. If he hits you, he'll knock you out. If you hit him, you'll knock him out".
** Roger Mayweather, who today is best known for being the long time trainer of his superstar nephew Floyd Mayweather Jr., was absolutely this when he was an active fighter. Roger had all the offensive skills of his nephew, (and more) and was a two-time world champion, however, unlike Floyd, Roger had neither a great defense (which has been his nephew's most famous attribute) or a strong chin. This resulted in many upset losses against opponents he should've easily beaten on paper.
* Mosquitoes. Their bite can transmit nasty diseases like Malaria, Dengue, Encephalitis and Heartworm, enough to kill a human or leave them bedridden for days. On the bright side, a well-timed smack usually kills them instantly.
* Spiders. Most species are venomous enough to kill most prey items close to their size with a bite or two, and a few of them, such as the Sydney Funnel-Web and the Brazilian Wandering Spider, have potent enough venom to be considered medically significant to humans (taken UpToEleven with the latter, when one of these spiders wandered into a young family's home in São Sebastiao, Brazil, and killed two infants.) On the receiving end, however, spiders usually go out pretty easily. Their exoskeletons are generally rather fragile, and if the abdomen takes substantial damage, that's usually enough to kill the spider, as most of their vital organs are located in that area.
* Hockey player Eric Lindros was widely heralded as "The Next One" by pro scouts in the late 1980s and early 1990s in reference to Wayne Gretzky, who was in turn called "The Great One" for being the all-time best player to ever put on skates. Lindros was the size of a train and dealt out hits to match, and was a highly skilled scorer to boot. When he made it to the NHL, he was both one of the most dominant and the most injured players in the league. The major reason he falls under this trope is because his head was as durable as a wet newspaper, and he suffered series of concussions that shortened his career.
* The Argentina national team was accused of this during the 2010 World Cup. Their dynamic and amazing offense blew teams away, until the Germans, who were able to shut down Argentina's scoring attempts, carved its way through the Argentines' notoriously weak defense in an absolutely brutal match.
** David Luiz, the most expensive defender in football/soccer. The Brazilian can deliver attacking free kicks without breaking a sweat- and he's a ''centre-back''. As for defensive ability... it came to a head in the 2014 FIFA World Cup ''in Brazil'', when he captained his side on a fateful day in Belo Horizonte. [[http://en.wikipedia.org/wiki/Brazil_vs_Germany_(2014_FIFA_World_Cup)]]
** '''Cristiano Ronaldo'''. He may be one of the top forwards in football right now, but he's been accused of not running back to help the defense when his team loses the ball. He may be excused for this due to the fact that his usual position (Left Wing) doesn't really call for players to run back on D (Unless they're playing a 4-2-3-1, 3-5-2, or a 4-5-1 formation), and that he's just extremely good. Nevertheless, some individuals have called him out for his lack of effort on defense, most notably his former manager Jose Mourinho.
* [[CarFu Cars.]] In developed countries, the amount of damage that cars inflict far surpasses guns, though they themselves fall apart if they hit things. To some extent however, the latter is intentional: modern cars are designed to crumple so as to protect their occupants.
* Airborne troops. They are the unquestionable elites of any army, but they are only light infantry (meaning no artillery or armour support) and require an absolute surprise element to be used efficiently. And shooting down the jump plane is likely to kill the whole stick...
* Birds of prey. They have sharp and strong beaks and talons, capable of killing their prey in a split second... but if grounded by a broken wing or leg they are very likely to die of starvation.
* Venomous snakes. Sure, they have a ''very'' nasty weapon at their disposal, but the instant their venom glands run dry they're reduced to bluff or flight. And if an attacker is too thick-skinned or immune, they're lunch.
* Combat Robotics has a surprising number of glass cannons. In ''Series/RobotWars'', Razer had an almost unstoppable weapon, but often broke down of its own accord. Tsunami and Wheely Big Cheese had immensely powerful flippers (but the latter was very difficult to aim) but lacked the durability to fight {{Lightning Bruiser}}s like Chaos 2 and {{Mighty Glacier}}s like Xterminator. In ''Series/BattleBots'', Nightmare had a massive 4 foot diameter spinning disc, and its destructive power was the original reason for the arena having a ceiling, but its wheels were very vulnerable. It lost after having a wheel (and sometimes the gearbox and part of the motor it was attached to) ripped off by horizontal spinners. Many "shell spinners" have huge destructive power, but if they get flipped over, they're toast. Finally, Last Rites, one of the current top-ranked heavyweights, practically defines this trope. Even the most heavily armored opponents cannot simply shrug off blows from its spinning bar, but it is lightly armored, and its wheels are vulnerable to a solid hit to the side. In fact, because its bar is so powerful, and so much weight is poured into the weapon system, it is frequently defeated by the recoil from its own attacks.
* The UsefulNotes/{{Prussia}}n army of UsefulNotes/FrederickTheGreat was renowned for its extensive drilling and exceptional discipline, complementing Frederick's aggressive tactics. He would often march his men to the battlefield under the cover of night, subsequently arranging his men in oblique order, whereby one flank of his army would be deliberately strengthened at the expense of the other. It worked very well when it was racking up victories under Frederick, who understood the considerable weaknesses of his technique; it heavily relied on surprise and would result in enormous casualties for his own side if his forces got bogged down in prolonged fighting. Moreover, his army was largely comprised of conscripts and mercenaries, neither of whom could be considered particularly loyal; undertaking campaigns for long periods of time would see the strength of his forces sapped by desertion. After his death, his army fell apart and by the time of UsefulNotes/TheNapoleonicWars, it was a PaperTiger.
* [[UsefulNotes/AustralianWildlife Irukandji jellyfish]]. They are the size of a fingernail and are so fragile they can't be kept in a tank - they will die from bumping into the glass. They also have venom that, while not particularly lethal, will hurt you so very much that you will wish it was.
* The legendary Mitsubishi [=A6M=] Zero, known for its exceptional agility, also had better armament than many of its rivals at the time of its introduction: many aircraft did not begin to incorporate 20mm cannon as main armament until after 1940, and the Zero had two of them, along with two machine guns. However, it was extremely fragile, with no armor and fuel tanks that would leak continuously from even the smallest puncture instead of sealing like Allied tanks. Multiple hits by machine gun bullets will literally tear the Zero apart, whereas a single hit from a cannon shell will almost certainly turn it into a fireball.
** This was a persistent problem for Japanese aviation in general, as their lagging engine technology and emphasis on turning maneuverability and long combat range meant stripping as much weight as possible from designs, namely armor and self-sealing fuel tanks.
* ME-163 Komet. It was a rocket fighter (only one ever produced) armed with two 30mm cannon or ten short ranged upward-firing single-use guns. It was designed to kill bombers with just a couple of hits and during its powered flight phase, [[FragileSpeedster moved too quickly to be targeted and hit by pretty much anything]]. However, it only had enough fuel for about 7 minutes of powered flight and once it expended its fuel, it was a nearly helpless glider. And in the event that something hit a Komet while it still had fuel, they were pretty much MadeOfExplodium as the two-part rocket fuel was hypergolic, igniting the moment it was mixed.
* The [=DeHavilland=] Mosquito was a twin-engine light bomber designed from the ground up as a FragileSpeedster. Initially unarmed (aside from its bomb loadout) and constructed with an all-wooden fuselage to save on costs and weight, it used its speed and high operational ceiling to evade interceptors. As the war continued, armed night-fighter and fighter-bomber variants were introduced that started to fit the trope, but none more so than the submarine-hunting variant which had a ''57mm anti-tank cannon'' mounted in its fuselage along with racks of rockets under the wings. And it was still fragile enough that pilots were told not to fire the main gun at ranges of less than 600 yards because shrapnel from the impact could cause serious damage.
* The [[DirtyCommunists Soviet Union]] produced an example. The 2B1 Oka was the largest self-propelled artillery piece ever built, and could fire a 420mm ''nuclear projectile'' from its 65-foot-long barrel up to 28 miles downrange. Unfortunately, the recoil of such a monster cannon was too powerful, damaging the gun mount, snapping the treads, and tearing up the transmission. Assuming it even could fire a second shot, it would be effectively a stationary artillery piece.
* Traditionally, archers in many armies did not wear any armor, partly because it would have interfered with their movements and also because they generally could not afford it. A particularly well-off bowman might be able to go into battle with a sword and buckler, a breastplate, and a helmet of some sort; most went off to fight with little more than their bow and maybe a kitchen knife for emergencies.
* In a way, elephants are this. They're strong and fairly fast as well. Yet due to SquareCubeLaw, tripping can seriously injure them.
* Guided missile warships certainly count. Modern anti-ship weaponry have such long range and sheer destructive power that armour doesn't really offer practical protection, so most ships are unarmoured except for certain key areas such as the [[MadeOfExplodium magazine]]. Instead, the extra weight is either removed from the equation to allow the ships to move faster, or used on more useful things, such as the aforementioned long-range highly destructive missiles. In short, modern shipbuilders take to heart the saying that the best defense is a good offense. Mind you, that does not mean that modern warships are completely defenceless: nowadays, ships rely more on [[ShootTheBullet intercepting attacks]] and avoiding detection to defend themselves.
** Also of note are the "Kirov" battlecruisers. Big and bristling with armament, their armor is only 76mm thick.
* The Japanese Mogami-class cruisers. Intended to conform to the requirements of the London Naval Treaty while maximizing armaments, the ships were designed for 9000 ton displacement while packing ''fifteen'' 6-inch guns[[note]]later [[MidSeasonUpgrade upgraded]] to ten 8-inch guns[[/note]] and a dozen 24 inch torpedo tubes. Unfortunately, the construction techniques that the Japanese were using did not quite pan out. The ships became notorious for their instability and structural weakness (the ship's armor plates buckled and split when the guns were being test fired!), requiring massive refit to make them serviceable. In the end, they weighed in nearly 4000 tons heavier than original design and somewhat unfairly came to be used as poster boy for how the Japanese grossly violated arms limitation treaties.
** Japan was not alone in this design philosophy in the 1930s. So called "Treaty Cruisers" would often pair heavy armament with light armor, hoping to maximise their combat utility while staying within the letter of the treaty. More than one American cruiser similarly saw its weight ballooning over the treaty limit when modifications had to be made when the initial design proved subpar for various reasons, to include seaworthiness (adding weight to the bottom of the ship was the simplest way to make it more stable in rough seas). A later revision to the treaty redefined cruisers based on their armament rather than tonnage, meaning that several of these light cruisers found themselves redefined as very thin-skinned heavy cruisers shortly before UsefulNotes/WorldWarII.
** A British observer stated: "Either those ships are made of cardboard or they lie". Turned out he guessed ''both'' right.
* Battlecruisers as a general concept were this: Large warships packing battleship armament with cruiser armor. The intent was for them to be swift-footed "Cruiser Killers", capable of both performing hit-and-run attacks on enemy merchant shipping and smashing enemy escorts or screening patrols. In practice, they proved highly vulnerable to enemy battleships in fleet engagements, since such large battles limited their ability to use their agility, and the battleships could shrug off what would be fatal blows to the battlecruisers. More importantly, they were no less vulnerable to air attack than cruisers were, but were substantially more expensive to build and replace.
* Military aircraft in general. They can attack incredibly fast, are hard to hit, and can cripple most military targets, but by their nature, have little armor, and if they take any damage, are likely to crash.
** Bombers in particular can deliver devastating payloads, but are large, less maneuverable than fighters, and can't perform as well in air to air combat. They're also the first thing targeted by enemy forces.
** Drones, like the Predator, take advantage of their glass cannon nature. Small, light, and made of fragile plastics, they are almost guaranteed to be utterly destroyed if hit, making it more difficult for enemies to recover their wreckage. Indeed, the fact that there is no crew to be concerned about gives even less reason to provide any armor.
** Last, but not least, the [[https://en.wikipedia.org/wiki/Boeing_YAL-1 YAL-1]]. A Boeing 747 fitted with a [[BeamSpam laser]] designed to down [=ICBMs=]. Sadly, it was cancelled because of the short range of its laser that puts it within attack range of enemy fighters[[note]]As well as the maneuverability you could expect of a plane so big, and that was originally a (civilian) freighter one[[/note]]. This wouldn't have been such a problem if it had any other way of avoiding combat like faster speed or improved weapon range.
* Motorsports
** Open-wheel cars are usually regarded one of the superior classes in term of functionality and raw power, but they are also very frail and are breaking down a lot more often. Due to their higher speed and exposed bodyworks, a seemly slight tap into a barrier or an opponent's car can seriously damage its parts. Even miscued spinning into a gravel can shut down the system altogether and force the racer to retire.
* A typical characteristic of Italian war machines since UsefulNotes/WorldWarI:
** The [[http://en.wikipedia.org/wiki/Vespa_150_TAP Vespa 150 TAP]]: a recoilless rifle mounted on, of all things, a Vespa scooter, requested by the French for airborne operations.
** The [[https://en.wikipedia.org/wiki/MAS_%28boat%29 MAS]] (it stays for "Motoscafo Armato Silurante", or "armed and torpedoing motorboat"). It's [[ExactlyWhatItSaysOnTheTin a motorboat with two torpedoes and, in the later models, sometimes a machine gun]], with early models made out of ''wood'' ([[JustifiedTrope they had tried out metal ones, but found that the wooden boats were faster and more difficult to see]]). They were among the smallest and most fragile armed motorboats ever, but managed to sink the SMS ''[[https://en.wikipedia.org/wiki/SMS_Wien Wien]]'' in harbour and, most famously, the battleship ''[[https://en.wikipedia.org/wiki/SMS_Szent_Istv%C3%A1n Szent István]]''.
** Italian warships built between the wars and during UsefulNotes/WorldWarII prized speed and firepower, being designed to operate in the calm Mediterranean sea and fight the relatively passive French navy. However, their design often left much to be desired in other areas. They were severely deficient in anti-aircraft armament, lacking in radar and sonar systems, and like so many other pieces of Italian machinery, were notoriously unreliable and difficult to maintain. At the Battle of Cape Matapan, the Royal Navy severely crippled the Regia Marina, utilizing their superior airpower and fire control technology to heavily damage or sink several Italian warships with virtually no damage sustained, and the loss of only ''a single aircraft''.
** In early UsefulNotes/WorldWarII, the main fighter aircraft of the Royal Italian Air Force was the [[https://en.wikipedia.org/wiki/Fiat_CR.42 Fiat CR.42]], a ''biplane''. As such it was extremely manouverable, and was even fast for a biplane (top speed of 441 kph, with an experimental variant being the fastest biplane ''ever'' with a top speed of 525 kpm), but was even flimsier than the Zero, and once the Allied pilots adapted to it their superior speed and toughness, alongside the heavier armament, started decimating the Italian biplanes.
** Italy revitalized the specialized tank destroyer concept with the [[https://en.wikipedia.org/wiki/B1_Centauro B1 Centauro]], a wheeled combat vehicle carrying a tank gun (a rifled 105mm in the initial version, a smoothbore 120mm in the Centauro II model) and relatively thin armour, though this can be remedied somewhat by the addition of modular armour plates.
