->''"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. 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.

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 a game of RocketTag. When the enemy tries to take out the GlassCannon 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. See also: CompetitiveBalance and PVPBalanced.

[[IThoughtItMeant Not to be confused with]] [[AbnormalAmmo cannons that launch glass projectiles]] such as the [[NamesTheSame Glass Cannon]] artillery unit in the game ''RiseOfLegends''.

[[folder:Anime and Manga]]
* 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, its head is sent flying into a church, but his hand is destroyed in the process.
* ''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.
* The BigBad of the final arc of ''Manga/RanmaOneHalf'' has powers bordering on a PersonOfMassDestruction and he can tank ''KiAttacks'', 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.
%% * Louise from ''LightNovel/ZeroNoTsukaima''. Just like the ''Manga/MahouSenseiNegima'' example, her partner/familiar Saitou is here to protect her while she prepares her insanely powerful spells.
* [[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 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.
* 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.
* 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.]]
* Shiki, TheDragon and (sort-of) SquishyWizard from ''Manga/BlackCat''. His ''normal'' attacks do more damage than anything this side of the TheHero, the BigGood, and TheBigBad's ''final'' moves, but he goes down with one ''pistol-whip'' from [[TheHero Train]].
* 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.
* 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.
* 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.)
* 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 but it takes an hour to charge so he needs to be protected while preparing it.
* 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.
* Alyssa of ''Anime/{{Mai-Hime}}'' 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.
* 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.]]
* 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.
* The Grand Cross from ''LightNovel/BodaciousSpacePirates'' can be considered as an example of this. It possesses advanced technology and high-tech weapons that can destroy spacecraft instantly. However, its shielding is very vulnerable to heavy bombardment.
* ''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.
* 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.
* ''Manga/{{Bleach}}'':
** Ikkaku's zanpakutou is unpredictable, dangerous and incredibly powerful. However, it breaks easily because the shikai is wooden and the bankai's overpowered force makes itself brittle. There's a heavy implication that his zanpakutou breaks so easily because Ikkaku is refusing to use his power correctly. Ikkaku himself is not this trope.
** Ran Tao in the anime filler Bount Arc is a very skilled kidou user but her stamina is heavily compromised [[spoiler: by [[OlderThanTheyLook her extreme age]]]].
* King from ''Manga/NanatsuNoTaizai'' 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.
[[/folder]]

[[folder:Board 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'' dice's worth of damage.
[[/folder]]

[[folder:Comic Books]]
* Many telepaths in ''Comicbook/{{X-Men}},'' such as Professor X, have powerful PsychicPowers but very weak physical attacks, and aren't of much use against opponents immune to telepathy (like robots).
** Similarly, 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, {{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.
* The same is true of Marvel magic users like Comicbook/DoctorStrange, ScarletWitch, or [[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.
* Much like the X-men with offensive powers is ''ComicBook/FantasticFour'' member Human Torch. His flame powers give him move high movement speed and an offensive edge. Unlike his allies he lacks any way to use his powers to defend himself other than flying out of the way.
* Humpty Dumpty in the ''Comicbook/{{Fables}}'' SpinOff ''Jack of Fables'' is an almost literal example, being a cannon that was {{bowdleris|ed}}ation into being an egg man.
* 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/X-Men}}'' 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 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.
[[/folder]]


[[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 ''{{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.
* 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.
[[/folder]]

[[folder:Film]]
* ''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.
* 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.
* ''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, none whatsoever), so they break apart as soon as someone shines a laser pointer at them.
* 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.
[[/folder]]

[[folder:Literature]]
* 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. Harry reasons that instead of being on the defensive, he should punish the other wizard in their back-alley duel. When ''dropping a car on the guy'' doesn't work, Harry realizes that he's boxing way out of his weight class. The guy in question is the current most likely candidate to being on the Black Council.
* 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 ''Ashes 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).
[[/folder]]

[[folder:Live-Action TV]]
* In an episode of ''Series/LoisAndClark'', SelfDemonstrating/LexLuthor creates a boxer that he believes can take on Comicbook/{{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/TheOuterLimits'' episode "The Camp" has super strong robots that are ludicrously fragile.
%% * 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.
[[/folder]]

[[folder:Podcasts]]
* 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 [[GlassCannon durability of a dry twig]].
[[/folder]]

[[folder:Tabletop Games]]
* 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.
%% *** This is absolutely the case with Dark Eldar vehicles. Unlike the Imperium's variant-based vehicles, their strongest armored vehicle has armor so bad that they are generally described as 'kites'. It's a rare Dark Eldar vehicle that can't be taken down with small arms fire. If you get a chance to shoot them, that is.
** Also in tabletop, 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.
* The ''Hunchback [=IIc=]'' [=BattleMech=] exemplifies this trope in the ''TabletopGame/{{Battletech}}'' universe. 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!
** 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.
%% ** The ''Hollander'' BZK-F3 light 'mech tonnage is mostly taken up by the gauss rifle on its shoulder. (The mech weighs 35 tons, where the Gauss Cannon takes up 15.)
%% ** There are a few vehicles like this, such as the ''Hetzer'' Wheeled Assault Gun, effectively a BFG mounted inside an armored box on a heavy truck chassis, and the tiny 5-ton ''Savannah Master'' - the fact that it was designed to take on an opponent ''four times'' its tonnage has to count for ''something.''
** 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.
* ''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.
* 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.
* [[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. It may be indestructible by battle, but having one on the field is just begging for your opponent to use it as a direct line to your LP... of course, you'll be able to return the favor next turn.
** Dragon Master Knight has a titanic ATK stat and an effect that makes it stronger, but it has no defenses whatsoever from card effects.
* ''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.

[[folder:Webcomics]]
* Webcomic/{{XRS}} Despite it's vaunted capabilities, the XRS is extremely vulnerable whens it's 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.
* PlayedWith 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}} [[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]].

[[/folder]]

[[folder:Western Animation]]
* Soundwave, of ''WesternAnimation/TransformersAnimated'', 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.
* Typical firebenders in ''WesternAnimation/AvatarTheLastAirbender'' have no special defensive abilities whatsoever. The only known defensive firebending technique was invented by Iroh by studying waterbending for inspiration, and it is very situational (only useful against other firebenders). 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 [[spoiler:Eddy's Brother had been dishing ''out'' pain all his life, but hadn't had it happen the other way around too often, 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 agily, and very hard to lay a glove on, but when Batman actually manages to do so, it seems to hurt her badly.
[[/folder]]

[[folder:Real Life]]
* Since the introduction of gunpowder in the High Middle Ages, Artillery Cannons are (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.
* Tank Destroyers. Popular back in WW2, they were ExactlyWhatItSaysOnTheTin -- usually armed with a tank-grade {{BFG}} to destroy enemy vehicles with great efficiency, using the mobility allowed by their lighter armor to flank enemy tanks and attack from [[WeakPoint the rear]]. 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. American tank destroyers during 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 bigger gun than friendly tanks and were [[FragileSpeedster extremely fast]]: the [[http://en.wikipedia.org/wiki/M18_Hellcat M18 Hellcat]] can clock up to 55 mph on good roads.[[note]]While the same is true for early German tank destroyers ("Panzerjäger" or tank hunter), later ones ("Jagdpanzer" or hunting tanks) were built with as much or more armor as tanks, making them a MightyGlacier, instead.[[/note]]
* The M36 Jackson had the excellent 90mm gun which could destroy any German tank at distance. Sadly, it had a Sherman chassis and a very lightly armored body.
%% * The Soviet IS-2 heavy tank from WWII. Its 122mm gun took ages to reload, but could penetrate a Panther tank -- completely. One Panther was observed being hit by an IS-2 shell, with the shell ''coming out the rear of the tank'', going straight through several inches of sloped armor, and several more inches of ablative armor (the crew). However, Panthers themselves, with much lighter (but still, for the era, very powerful) 75mm gun, could also penetrate IS-2 armour right back.
* Another example:[[http://www.sinodefence.com/army/artillery/type75at_105mm.asp This]]. It's basically a Jeep-like vehicle with a recoilless rifle (think "bazooka") mounted on top. Or how about [[http://en.wikipedia.org/wiki/Vespa_150_TAP this]]: a recoilless rifle mounted on, of all things, a Vespa scooter, designed for airborne operations.
* The Swedish UsefulNotes/ThirtyYearsWar era [[http://en.wikipedia.org/wiki/Leather_cannon Leather Cannon]], which could well be the TropeNamer. It was basically a copper barrel wrapped on stout leather, like cow hide. The idea was to make the cannon light enough to be 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.
* 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, even to some extent being armed simply to defend themselves without their planes, is usually considered a waste, while the embarked aircraft give the carrier the effective ability to engage and destroy a wide variety of enemies anywhere in a radius of several hundred miles or more.
** US carriers generally avert this, as they do carry a point-defense gun (that is, a specialized, automatic anti-missile multibarreled cannon with an absurd rate of fire) on port and starboard of bow and stern. This is partly US Navy doctrine to mount point-defense guns on ''everything'' (even supply ships that shouldn't ever get remotely close to any action carry them), and partly a reflection of the former [=USSR=] having developed large, long-range anti-ship missiles for the specific purpose of killing US carriers in the event of an actual war.
*** Almost all carriers still carry some measure of self-defense, especially against missiles. However, in 1920s, carriers were designed to carry cruiser guns, just in case they got into shooting match with surface warships (USS Lexington and Saratoga, for example, originally carried eight 8 inch guns, same as a contemporary heavy cruiser.) Post World War II Soviet carriers were heavily armed with dozens of launchers for surface-to-surface and surface-to-air missiles, to combat surface warships directly. Compared to these vessels, modern US carriers are aviation specialists.
* Light tanks by definition are supposed to be very mobile, protected from small arms and constitute a serious danger. E.g. Soviet BT Tanks: on most BT-5s, 45-mm longbarrel cannon, armour 10-13 mm -- price of max speed 52 km[=/=]h on tracks and 72 on wheels. Some light tanks just go over the top, however. Look at [[http://epizodsspace.airbase.ru/bibl/shirokorad/ot-min/244.jpg this]] experimental [[MilitaryMashupMachine monstrosity]] (1936-1936). It's a launcher for two fortification-busting 245-mm missiles slapped on BT-5. Max range is 1500 m. Failed [[IncrediblyLamePun to hit]] production run as unfit for real assault due to its crappy accuracy, slow reload and -- surprise -- fragility from top to bottom. Normally light tanks have nothing to do within visual range from enemy fortification even without extra explosives strapped on top.
* Nuclear missiles without silos are arguably the ultimate example of glass cannons in real life, especially in the context of a nuclear war. Ballistic missile submarines have torpedoes, but they would still be in deep trouble if found. Mobile ground based units are even worse, with [[http://en.wikipedia.org/wiki/File:SS-25_Sickle_in_Siberia.jpg no defenses at all]] against the inevitable enemy counterattacks. Of course, you're supposed to just leave before the counterattack anyway.
* The torpedo boat was a small but maneuverable ship that had powerful armaments that could be used to sink the much bigger battleships of the era, and relied on its [[FragileSpeedster speed and agility to avoid getting destroyed]]. Navies fielding torpedo boats also relied on [[WeHaveReserves having lots of them]] to make up for any losses.
* Conventional submarines (at least up to and including WW2 vintage) also qualify -- great for crippling or killing enemy surface vessels from ambush, but they have to get fairly close to do it and again their only real defense against anything that can shoot ''back'' is not to get hit in the first place.
* [[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.
* Humans in hunting situations. If the guns fail to bring down that bear before it closes into close quarters, prepare for a trip to the hospital. Or to funeral home.
* Humans in warfare are generally a case 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 of the NFL's Indianapolis Colts. One of the league's hardest hitters, maybe the best safety in all of football... when he's healthy, which is about as rare as the Colts beating the Chargers these days. Sanders frequently spends half the regular season on the injured list, which might be because he plays so hard all the time, running full-force into offensive players on every play.
** 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]]".
* 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.
* Several examples in mixed martial arts, including fighters that have devastating offense and a weak chin.
** [[ScaryBlackMan Bob Sapp]] 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 ''[[MartialArtsDoNotWorkThatWay 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.
* 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 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 hurt 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]]. When attempting to move up a weight, Jackson was smashed up twice by Gerald McClellan, whose career was subsequently ended by another fighter with Glass Cannon tendencies: Nigel Benn was also a boxer with an almighty punch but a suspect chin, who was knocked down twice during the fight but got up and finished by putting McClellan in hospital.
** Some would say that British heavyweight Frank Bruno was also a Glass Cannon. A punch that could stop almost anything if landed properly, but a bit slow and unwieldy, and against top opposition, liable to be vulnerable to a big hit, not because he would get knocked down - which might have given him some time to recover - but because he would stay on his feet while stunned enough for the subsequent series of punches to finish the fight.
** Late in Mike Tyson's career Tyson's old trainer Kevin Rooney who coached him in his prime 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".
** Manny Pacquiao became a superstar boxer because of his freakish speed and strength which he used to overwhelm his opponents into submission, despite his small size. However, Manny Pacquiao also has a very fragile chin that can get damage when timed right. Earlier in his career, Pacquiao could easily get knocked down and out. However, after mastering his offense under the training of Freddie Roach (a well known offensive trainer), Pacquiao went a decade destroying some of the top boxers of his generation. That is until his nemesis [[TheRival Juan Manuel Marquez]] who he could never get a clear victory over, once again exposed his weakness by brutally knocking him out in their 4th fight by a well timed counter hook.
** Roger Mayweather, long time trainer of Floyd Mayweather Jr. had all the offensive skills of his nephew and was a two-time world champion. However, unlike Floyd Mayweather Jr., Roger Mayweather didn't have the great defense or strong chin. In fact, Roger's chin was so fragile that even the slightest force against it could cause him to get knocked out. This resulted in many upset losses against opponents he should've easily beaten on paper. The biggest example is against [[https://www.youtube.com/watch?v=L5k-q82K5Rs Rocky Lockridge]].
* Mosquitoes. Their bite can transmit nasty diseases like Malaria, Dengue, Encephalitis and Heartworm, enough to kill or cripple a human for days. On the bright side, a well-timed smack kills them instantly (usually).
* 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 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)]]
* More or less the situation with human-held firearms these days. Armor is [[TwentyFourHourArmor bulky and unwieldy]] and guns and ammunition that can penetrate said armor are readily available, even for common criminals, so often it comes down to trying to make sure that you can shoot first and that your opponent can't shoot back.
* [[CarFu Cars.]] Arguably better at killing people and destroying things than guns, but quickly fall apart if they hit things. Granted the things they're good at destroying and the things that destroy them if hit aren't one and the same, but since you're from Column A, it's still a good idea to look up from your smartphone before you cross the street.
** Older cars were sturdier. Modern cars damage easily in an impact because it's realised that what matters is not whether the car is damaged but whether the *occupants* are, so crumple zones are better than a really rigid shell.
* [[BigBadassBirdOfPrey 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 also. 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 [[LightningBruiser Lightning Bruisers]] like Chaos 2 and [[MightyGlacier Mighty Glaciers]] 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 Prussian infantrymen of FrederickTheGreat were renowned for their rapid rate of fire (pretty impressive, given the rather slow firing rate of muzzle-loaded muskets) but were pretty vulnerable in close combat, making them a ripe target for cavalry. Fortunately, Frederick was enough of a tactical genius and a lucky man to prevent decisive defeats.
* [[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 a venom that, while it is not lethal, will hurt you so very much that you will wish it was.
* The Mitsubishi [=A6M=] Zero was extremely fragile, with no armor and fuel tanks that would leak continuously from even the smallest puncture instead of sealing like Allied tanks, so that even the most minor glancing hit could destroy it. It also had better armament than any of its rivals and could blast apart most Allied aircraft with a single burst, and a turn rate good enough to get into a firing position against even the most elusive enemy. It was the king of the Pacific skies until faster American fighters showed up that could simply barrel down on a Zero from above, destroy it, and run away before the Zero's wingmates could respond.
* ME-163 Komet. It was a rocket fighter 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, moved too quickly to be targeted by the prop driven Allied planes. 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.
* The [[DirtyCommies 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 it's 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 a knife and the clothes on their back (and sometimes even less than that). Suffice to say, archers tended to get slaughtered if the fight came to them.
* In a way, elephants are this; they're extremely powerful, and fairly fast as well. Yet due to SquareCubeLaw, tripping can greatly injure them.
** War Elephants are not much better. Sure, they seem like they would be a Mighty Glacier at the very least, able to suck up lots of arrows and trample enemies, but they scare VERY easily, uncontrollably running away, often through friendly lines.
* Modern Guided Missile Warships certainly count. The CG-47 "Ticonderoga" class cruisers started life as destroyers, but with some design changes (and some meddling from DC) they became cruisers. To give you an idea of what this means, think of it this way. Each 'Tico' is armed with two 5" rapid fire cannons for short range work, as well as Harpoons and Tomahawks for long range work. Both of those missiles are capable of ripping other ships apart from many, many miles away, and the 5" guns can track anything from small boats to low flying aircraft, and reliably take them down. But the armor is made of KEVLAR. Yes, the EXACT same material that soldiers put on to protect them from bullets. This was done to save weight since the hull was never designed for cruiser specs. Those aboard a Tico better hope that the [[OhCrap AEGIS combat system doesn't Blue Screen...]] Not that armor would be of any value against modern anti-ship missiles however, especially as the primary means of damage is fire not the explosion itself.
** Also of note is the "Kirov" Class of Battlecruisers. Each ship is armed with a an array of the appropriately named "Shipwreck" Anti-ship Missile, but the armor is only 76mm thick. There's been an ongoing debate over what would win, an Iowa or a Kirov. However, since the Iowas would likely be protected by the aforementioned Ticonderogas, and their GC Brothers the Arliegh Burkes, the Kirov would have to rely on a [[MacrossMissileMafssacre Macross Missile Massacre]] to hopefully destroy the battlegroup. [[OhCrap If it fails to do so...]] In this case it would be the destroyers that would be doing most of the defensive work, the armor and big guns of the battleship would be almost entirely irrelevant in terms of winning such a battle, although the Tomahawk and Harpoon missile launchers which were [[MidSeasonUpgrade fitted to the battleships in the 80's]] would give them an ability to shoot back.
** Most modern warships fall under this design philosophy. Modern anti-ship weapons have such long range and sheer destructive power that it is simply impractical to carry enough armor protection to be useful, except for certain key areas such as the ship's [[MadeOfExplodium ammo 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.
** This is also part of the reason why cruisers have largely disappeared from the order of battle in modern navies. Given the lack of relevance for armor or big guns, missile-equipped destroyers have ballooned in size and capabilities, effectively filling the role of cruisers in both size and capabilities.
* World War II era 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 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.
* 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.
* European main battle tanks of the ColdWar: they were well armed, but their armor was very thin, relying on speed for defense.
