-->"At first glance, Green Lantern seems like the only Superfriend who's up to Superman levels of power. He can make anything he wants just by thinking about it, plus he has a snazzy outfit. But then there's his weakness: yellow. A primary color, for God's sake! 'Big Bird! You have defeated me once again!' 'Lemon-scented dishwashing liquid! Lo! I am foiled!' 'Marshmallow peeps! [[BigNo Nooooooo!]]'"

Being a SuperHero ain't easy. Most of the original {{Flying Brick}}s have the good [[AchillesHeel Achilles heels]] covered, and the pharmacy is even out of PsychoSerum to give you a cheap {{Backstory}} gimmick to explain your powers.

What's left for the modern hero and villain to do? Make do with a Weaksauce Weakness. It's great for comedic effect, but just as often it ends up being an AchillesHeel that makes your average MundaneSolution seem [[DramaPreservingHandicap perfectly reasonable]] by comparison.

The weakness isn't a common household cleaning agent like MundaneSolution, but something so incredibly, stupidly embarrassing you'd think the SuperHero would never use his power out of shame in the off chance someone found out about it, or because it [[KryptoniteIsEverywhere shows up regularly]] in the course of their super heroing. The "weakness" might come in the form of the fuel for the super power, a humiliating TransformationSequence or activation phrase, or just a set of restrictions on the powers that really are begging to get laughed at. Therefore, this is one of the most popular ways to [[BlessedWithSuck Bless your hero With Suck.]]

[[folder:Fiction in General]]
* Vampires, the badass creatures of the night who always want to suck your blood. But you're fine as long as you stay in the sunlight, have some garlic, stay inside your house and refuse to let them in, or even wield a simple cross. [[OurVampiresAreDifferent In some media]], silver works too, along with other religious symbols. Making this one of TheOldestOnesInTheBook.
** Remember, this makes a nifty curfew ("Stay in your house, and you'll be safe; ignore the king's curfew, and you'll be lunch!") and powerhold for king and clergy since few peasants could afford garlic much less silver and none could bless their own crucifix.
*** Their only saving grace then would be that a vampire has to be invited into one's home, although depending on how crafty a vampire is and how literal they interpret it, your welcome mat may doom you.
** Sure, maybe with ''[[YourVampiresSuck your]]'' vampires. Not to mention that many of those weaknesses are relatively recent. Old, but not that old.
*** ''Poppy seeds''. Apparently just that OCD.
*** [[SesameStreet ONE! TWO! THREE! FOUR! AH AH AH AH!]]
** Or standing on the other side of the river. Or giving them a large bag of rice.
*** Slip 'N' Slides are also fairly effective.
** If {{Blade}} is to be believed, UV lights will do it, too.
*** That's because, in Blade (the movie), it's the UV rays from the sun that do the damage; not a new weakness, just a clarification of a pre-existing vampire susceptibility.
*** Of course, in the Blade comics, he once killed a vampire by blowing its head off and leaving it to starve.
**That's not weaksauce that's just..... fucking awesome.
**You'd think being so ancient, they'd have figured out ways to overcome some of these things. Someone won't invite you into the house? Set it on fire and let them come to you. Guy on the other side of running water? Purchase a decent hunting rifle. Religious symbols? Become an atheist.
*** A group of vampires in {{Angel}} did try the "smoke 'em out" approach. I doubt being an atheist would protect against holy symbols in a world where supernatural powers are pretty clearly a fact.
*** Spike figured that out as well. Angel explains to his friends they are in danger because while Spike can't enter the place, he can certainly torch it from the outside.
**** It [[OurVampiresAreDifferent it depends on the world]]. Sometimes the holy symbol needs to be of the vampire's religion; sometimes it needs to be of the wielder's religion, and [[BuffyTheVampireSlayer sometimes it needs to be a cross no matter what]].
**** TerryPratchett wrote [[Discworld/CarpeJugulum a book]] about a group of vampires who try this (See below). It has mixed effects.
*****Actually, by that Logic, Atheist Vampires would still be vulnerable to an A with atoms flying around it. But the ones who's REALLY be screwed are Agnostic Vampires, THEIR symbol is a question mark!
****** "?" AND LO! THIS PAGE IS SAFE!
****** Assuming the atheist doesn't believe in God due to logical argument it should be possible to stop them with syllogisms. If it's simply a belief that science explains things better then ''anything created by science'' might kill them.
***** (^^ MadeOfWin) *lukethedudeduke sighs, and prepares to recite the phrase he's said many a time* Atheism is ''not'' a religion. It's defined as a lack of faith, and we don't worship or bow before the "A", depriving it of any ritual significance. A cross, on the other hand...
***** In the DoctorWho episode "The Curse of Fenric," it was actually psychic energy that affected vampires. So, it was the person's ''belief'' in the cross that pushed them back as opposed to the actual object. So, if you believed in something else quite strongly (like the symbol of the Soviet Union in one case), you could use that instead. Or if you're the Doctor, you're just so cool that you don't actually need a physical object to focus that psychic energy, and you can just push them back with your mind. Of course, that means that if you don't actually believe in the cross, it doesn't do you much good since you wouldn't be able to use it to muster up your belief/psychic energy. [[spoiler: Indeed, this is what happens to a vicar in the story - he has lost his faith due to the brutality of the Second World War, in which the story is set, and he attempts to repel vampires with Christian symbols and fails utterly.]]
****** During the final episode the Doctor's companion Ace [[spoiler: holds the lead vampire at bay using her faith in the Doctor. The Doctor having to break her faith in him for the greater good is a major event at the story's climax.]]
****** Actually, he's muttering something that's not clearly heard on screen. In the novelization by the same author, it's more clear that what the Doctor is muttering is [[ThePowerOfFriendship the names of his companions]]. That's what he bases his [[CrowningMomentOfHeartwarming strong faith]] on. Knowing this while watching the episode it's actually possible to tell which companions he's naming - he starts with Susan, Ian Chesterton and Barbara Wright, the first three companions to be shown in the series, before working his way forwards. In line with this "it doesn't matter what your faith is ''in'' as long as you use it" idea, at this point in the story the vampires are swarming through an otherwise empty church without suffering any adverse effects from the religious imagery.
****Similarly, in {{Thunderstruck}}, religious symbols harm vampires because, when made and/or wielded by a person of faith, they are imbued with a piece of that person's life essence, essentially causing the vampire to "overdose" on life force (which is what they're actually consuming when they drink one's blood). This leads to some confusing issues: for instance, the cross set up in a church may be harmless to the vampire if the churchgoers there are only paying lip service to the religion, but a [[KatanasAreJustBetter katana]] forged by a traditional Japanese swordsmith is as dangerous as any holy symbol, due to the smith's intense devotion to the art and the various traditions involved.
**** This is actually awesomely explained in Richard Matheson's short story ''IAmLegend'' (not the Will Smith movie):
***** Robert Neville discovers that the aversion to garlic is an allergic reaction with the bacterium that causes the "vampirism" in them, that crosses' effectiveness are purely psychological based on the person's religious belief beforehand (meaning the Star of David would work on Jewish vampires), and that the rays of the sun react violently against the bacterium, which is why vampires are strongly averse to it ([[spoiler:though they were starting to develop cures for it towards the end of the story.]]), and staking pretty much worked no matter where you stabbed them, due to the fact that the bacterium needed to be within an enclosed environment within the body, and that bullets didn't affect it because they went in quickly (and out quickly) whereas stabbing them with something would force the flesh to remain open, causing a reaction with the bacterium that resulted in rapid putrefaction of the flesh, which due to some of the vampires being dead beforehand, would result in becoming ash.
** If you're a [[{{Twilight}} Twi-pire]], your only weakness is thinking your true love dove off a cliff.
*** And fire.
****Rra! Fire bad! Not dazzle me!
** In the comic strip {{Yamara}}, formerly published in ''{{Dragon}}'' Magazine, vampires were all unique. The common weaknesses of sunlight, holy symbols, garlic, etc, were just the most common weaknesses. The vampire villainess Persephone had none of the traditional weaknesses. But in life, she had always avoided doing her own laundry, so in undeath she was cursed to flee from laundry products, lest underneath their power she wither and perish. So baskets of dirty clothes, bottles of detergent, clothespins, lines of laundry hanging up, all these made her shrivel, weaken, and could have destroyed her. (As Persephone's friend the Drow Priestess said, "My goddess, you must feel pathetic.")
*** Except when they went to DarkSun, where it wasn't such a WeaksauceWeakness after all.
---> '''Persephone''': "How can laundry products possibly defeat me ... on a world with ''no clothes''?"
** Many of the features of vampires in BloodRayne are complete WallBangers, even those that are just barely graced by the RuleOfCool exemption. But water? Not even holy water, or even running water, Rayne gets owies from stepping in a gutter. A fire alarm sprinkler system can wipe out a building full of them.
*** The vampires in {{RIFTS}} and the LegacyOfKain series share this weakness. The weapon of choice for savvy {{RIFTS}} vampire hunters is a man-portable sprinkler system/garden hose.
****Otherwise known as a Super Soaker.
*** Vampires from ''{{Grendel}}'' are hurt by water, but apparently aren't killed by it unless they're totally submerged. When they're rounded up and locked in internment facilities, the guards turn on the sprinklers as a riot-dispersal tactic.
** In ''{{Discworld}}'', one family of vampires decides to work up an immunity to such things. Their grandfather chides them for this as it is unfair to their enemies.
*** Also in Discworld: They all think that nobody will recognize their names spelled backwards.
*** Not a new one. It's a reference to ''Son of Dracula'', in which a vampire conceals his identity by calling himself "Count Alucard". ''Carmilla'' did something similar with anagrams, using the names "Mircalla" and "Millarca".
** Remilia Scarlet and Flandre Scarlet of ''{{Touhou}}'' are vampires with most of the strengths and essentially ''none'' of the weaknesses. (Direct sunlight weakens them, but does no overt harm, while their powers hit zenith at the full moon.) This is kept from being a GameBreaker by the fact that ''everyone'' has [[FlyingBrick flying, insane damage resistance, and superstrength]], so vampirism largely just means "drinks blood" or [[{{Portal}} eats suspiscously red cake]]. They [[ComboPlatterPowers have to add in extra superpowers]] to make them threatening.
** Here's a coupon for tropers wishing to try one of the thirteen plus flavors of weak [[IncrediblyLamePun sauce]] weaknesses found in ''[[VampireTheMasquerade Vampire: The Masquereade!]]'' There's the standard ones that apply to all clans: sun and fire can potentially incinerate, wooden steaks cause a coma, etc. However, every clan and sub-clan had an extra defining weakness handed down from Cain or some other magical malarkey. A few choice ones are: Nosferatu - so ugly they can't pass for human, Malkavian - become incurably insane, Gangrel - slowly have animal parts replace their features, and Giovanni - their bite is every bit as painful as it should be. Then there's a few clans that got off near scot free: Lasombra - cast no reflection, Tremere - technically none, but their elders put them all under indirect MindControl, and in practice Toreador and Ventrue. The former are supposed to suffer {{OCD}} when seeing anything "beautiful", but an inattentive GM can forget to have them roll to resist this periodically; while the latter can only feed from one kind of mortal, which depending on the restriction can be anything from a non-issue to un-life threatening.
* TheFairFolk are terrific, in inspiring terror, beings of legend and myth. They can be beaten by a stick of iron, a horseshoe, a length of rowan wood, wearing clothes inside-out, or a ''stick of bread''.
** ''[[TheWorldOfDarkness Changeling: The Lost]]'' has the concept of "frailties", little weaknesses that certain fae (and overly-powerful changelings) are prey to. Some of them are the classic faerie weaknesses, others can be as odd as "must drink alcohol instead of water" or "cannot cross lines of ants". The only universal weakness is iron, which isn't as dangerous as you think because pure iron is rare... and ''steel'' does nothing.
*** Uh... so a 0.2% carbon content (low carbon steel) ruins it? Anyway, pure iron isn't that hard to find... wrought iron is as pure as iron gets (with carbonized "slag inclusions" running through it like wood grain).
***It's actually a [[DealWithTheDevil technicallity]] without any relation to physics. Only weapons (whether manufactured or improvised) - made from iron alloys with the word "iron" actually in their names - can harm faerie creatures. [[{{Wallbanger}} This applies even if the conflict takes place in a non-English speaking country where iron alloys have different names.]] This is also the reason why the iron-based hemoglobin in blood doesn't boil them alive from the inside out and why they can eat iron-rich cereal without burning themselves.
** Most of those serve only to frighten off TheFairFolk from killing you right now, more things they don't like than things that can kill them; they'll come back when your guard slips.
** MercedesLackey has fun [[PlayingWithATrope playing with]] the iron weakness; in her [=SERRAted=] Edge book series, the good elves not only use their skills as ''race car mechanics'' to work up a tolerance to iron, but also gladly use the metal to shield themselves from enemy elf attacks.
*** It's also noted that magic goes haywire in the presence of iron (the human wizard accidentally gave an elf a reverse mohawk when his spell ricocheted off a piece of iron)
**** ... Sorta right. Only Elf magic (TM) is affected by the presence of iron or silk. The mage in question actually was just REALLY crappy at aiming when tired. She specifically had one point in the same book where the Noodle Haircut was mentioned where two sheet-metal cars are parked in teh middle of a battlefield, with the line "The human's spell-bolts flew straight and trew, the elf-shots curving gracefully..."
** This troper remembers hearing somewhere that the Fair Folk weakness to iron is specifically to ''cold-wrought iron'', which is a threat to them because it represents the strength of humanity in being able to shape iron without having to use heat to soften it first.
*** This is a later invention; the original story was that faeries fear "cold iron", which at the time was just a poetic way of saying "iron" -- the same way we might refer to "cold steel".
** It makes a lot more sense when you consider the symbolic property of a lot of these things: Both iron and bread are ''cultural'' (as opposed to natural) artifacts (bread especially is a very common symbol of civilization) and since TheFairFolk are usually seen as representations of wild or unpdredictable Nature...
*** That may be only part of it. Many traditions allow the Fae to use weapons and implements of smelted copper or bronze (a copper/tin alloy). This may be a later inclusion resulting from the conquering of Bronze Age cultures by emerging Iron Age ones, due to knowledge of ironworking giving the latter much superior weapons and armour.
* While the [[OurWerewolvesAreDifferent werewolf]] weakness to silver is a relatively new invention, earlier legends provide such weaknesses as having an iron bar thrown over their head, drawing three drops of blood, or having their name announced one to three times.
* Many of the oldest portrayals of {{Satan}}, the ostensible antagonist to {{God}}, has him easily outwitted by peasants and driven away by holy symbols.
** He is also afraid of a scapular (look it up.)
**It gets even more embarrassing than that. According to the Bible, all you have to do is say "Jesus" and all demons flee. So, if Satan comes out of the depths of Hell to steal your soul, all you have to do is say "Jesus" and you're safe.
*** That is ''not'' what it says. You're probably thinking of Mark 16: "...these signs will accompany those who believe: In my name they will drive out demons..." However, it's clearly the power of the speaker's faith that's being invoked here; and in any case that part of the chapter is not present in the original texts, suggesting it was added at some later date.
**** In other cases it's the Apostles who are throwing out demons and such, and their power isn't based on some magic word, but because they were specifically given that authority by Jesus at the Sending of the Twelve.
**** At one point some apostles report having seen another person throwing out demons, and Jesus says not to stop him, because anyone who's doing miracles in his name is doing his work. This doesn't claim anyone can throw out demons, only that there are some other than the Apostles who can.
*** The New Testament itself subverts "saying Jesus means you're safe" in Acts 19, when a team of (fake) exorcists try invoking the name of "Jesus Christ, whom Paul preaches" in a magic-spell type fashion (and one assumes, without believing in Jesus themselves). The demon replies (paraphrased): "Jesus I know, and Paul I heard of, but who the fuck are you twerps?" and [[CurbStompBattle beats the shit]] out of them.
*** Keep in mind [[{{Satan}} Old Scratch]] worked differently in the dark ages, generally by ''making them dark''. Plagues, falling asteroids, ruined crops and such were his line of attack, not corrupting bishops and driving kings mad (as in the middle ages), or bargaining for souls (as in more recent times). If a peasant got close enough to mess with Satan's head, he was already doing something wrong. These days, calling on Jesus Christ or a favored saint has a better chance of stopping a [[{{ptitleeyyr8ln8spjv}} bear]] than a given agent of evil.
*** Saying "Jesus" may not have that big an impact. Praying to him, on the other hand is a great idea when confronted with the [[TheLegionsOfHell Forces of Darkness]]. Having some holy water or blessed salt near by is also a good idea.
* Basilisks. Okay, they can kill you if you look directly at them, or hear their voice, or if you touch them, but guess what? They can be killed instantly by the crowing of a rooster, and their powers don't work on [[IAmNotWeasel weasels]].
** Which is great if you're a farmer or a weasel herder, but it's not like a whole lot of people have easy access to live poultry when the ''doom snake'' is breaking down their door...
*** Well, if a record of a rooster cry works, internet helps to do so. In seconds.
**** Assuming that it does work, what if your internet just so happens to not work?
***** Further discussion of this scenario likely falls under CrazyPrepared...
** There are stories of men killing a basilisk by wearing ''mirrors sewn into clothing''.

[[folder:{{Anime}} and {{Manga}}]]
* Tobor, the ''EighthMan'', recharged his powers with an inhalant stored in small, thin, white tubes that he carried in a cigarette case. When the bad guys allowed him "one last smoke" before executing him, this was great; when he was having a fight where kids could see him, he worried about setting a bad example by appearing to smoke.
* In ''OnePiece'', protagonist Monkey D. Luffy has "infinitely stretchy limbs" and (if he really, REALLY tries) is strong enough to smash a city with one punch. His weakness? The magical source of his powers also curses him to be ''completely unable to swim''. Which is kind of a problem, seeing as how he's a ''pirate''.
** The inability to swim is an established weakness for all devil fruit users. Which makes you really wonder why so many of them take up piracy...
*** The One Piece world appears to be largely made up of island chains and huge oceans, with very little continental land, so sailing in general is a common activity. Secondarily, ''finding'' a Devil's Fruit means searching far and wide, which pretty much limits it to pirates as far as who's going to run into them.
*** Fun scene: At one point, Luffy falls into the ocean and starts to drown. Nami, Chopper and Brook promptly leap into the water to save him, apparently forgetting Chopper and Brook are BOTH devil fruit users...
*** Any body of deep water (freshwater does it too, though they can shower without getting paralyzed) causes them to weaken to the point where they can't move. Some powers (like Chopper's transformations) are completely canceled, while others (like Luffy's rubber body) are left alone but can't be used because he can't move. In one early arc, Luffy's stuck underwater and he survives because someone grabs his head and stretches his neck until it's above water until they can break him free of the block of concrete keeping him underwater.
***Water is actually a much greater weakness to [[BigBad Sir Crocodile]], as he is a man who can turn into sand; if water strikes him, the sand "sticks together", and he is rendered unable to turn into sand at all, thus leaving him fully open to attack.
***Crocodile, on the other hand, has a natural defense in that his sand powers extend to causing [[NightmareFuelUnleaded alarmingly fast dehydration]] with direct skin contact. In addition, he has the [[DangerouslyGenreSavvy good sense]] to not only do his villainous business on a relatively large island, but on a ''desert island.''
*** British sailors in the 19th century hated eating fish or any food from the ocean for that matter, preferring weevily biscuits and gruesome salt pork or beef to fresh fish. Sailors hate the the sea, pilots hate the wind, and retailers hate customers -- WeaksauceWeakness in its truest form.
**** Pilots don't actually hate wind, we just get annoyed when it won't go the right direction for where we're trying to go!
**Excuse this troper for asking, but if he had infinitely stretchy limbs, why wouldn't he just stretch his legs to the bottom on the body of water he was in?
***Unlike most rubbermen, he can't stretch (and stay stretched) at will, but rather uses momentum to pull it off. So even if he could kick the ocean so hard to reach the bottom, it'd snap back pretty quickly. Oh, and the weakness kicks in at about half-immersion.
* The specialists, the Paper Sisters in ''[[ReadOrDie Read Or Dream]]'' can telekinetically manipulate paper... unless it's ''wet''. This was not a weakness for Yomiko, who ''is'' shown on camera manipulating paper while underwater.
** I believe it's established that you have to be ''really good'' to manipulate wet paper.
* ''SuperDimensionFortressMacross'' has an alien attack force made up of gigantic ScaryDogmaticAliens who are a [[ProudWarriorRaceGuy proud warrior race]] do a mass MookFaceTurn because of... singing. And souvenirs. In fairness, it does make sense in the story (at least as much as ''WarOfTheWorlds'' Martian's being vulnerable to Earth's diseases) and is perhaps one of the best logical conclusions to a typical alien's PlanetOfHats treatment. The aliens have no culture to speak of other than fighting, so when exposed to humans and their culture in the form of songs and interacting with the other gender after sending a team of spies to the SDF-1, typical Zentradi start feeling emotions, questioning their purpose, and [[WhatMeasureIsANonHuman becoming similar to humans.]] Because of this, their entire fleet gets deemed "contaminated" by the unexposed Zentradi and programmed for destruction. In the face of this EnemyCivilWar, they wisely choose to ally with the humans. Still, it doesn't quite wash away the faint air of ridiculousness when Minmei's singing becomes an ''offensive weapon'' to unbalance the unexposed Zentradi in their attack.
** Those who consider Minmei TheScrappy half-jokingly argue the Zentradei were distracted by her singing because [[DreadfulMusician it was so bad.]]
*** Taken to even greater extremes in Macross 7 where the enemies, the spirit draining Protodevilins only weakness is actually the energy produced by music, which produces a spiritual energy to pure for them to absorb and regenrates the lost energy in those drained by them.
* In ''RosarioToVampire'', vampires are considered the high end of the monster scale, but the fact that you can pretty much take a vampire down with a glass of water kinda puts a [[IncrediblyLamePun dampener]] on that idea.
* The titular hero[[GenderBender (ine)]] of ''[=~Ranma ½~=]'' can be incapacitated by [[WhyDidItHaveToBeSnakes the mere sight of a cute little kitten]]. However, those who attempt this should note to apply said weakness quickly and forcefully -- prolonged, intense exposure has a tendency to [[UnstoppableRage backfire]]. Thanks to his GenderBender curse, cold water can also count as a weakness. Technically. Ranma's female form has less strength and reach than his male form (though the anime is explict that Ranma's speed is boosted in this form, so it's more of a trade), but s/he can still pull off all of his/her normal attacks. Based on a character with an identical curse, it's also possible that being in female form weakens his {{Ki Attacks}}.
* My name is [[SakigakeCromartieKoukou Yutaka Takenouchi]], and I have only one weakness... I am VERY susceptible to motion sickness!
* Natsu from ''{{Fairy Tail}}'' is MadeOfIron, he can breath fire and cause [[PersonOfMassDestruction massive property damage simply by punching someone]], but he too suffers from the ignominious suspectibility to motion sickness. At least once it was actually exploited to defeat him in battle.
* Apparently, [[{{Bleach}} Chad]]'s main weakness is cute and cuddly things, as he wants to hug them to no end. If it'll be used by an opponent in the future, we don't know. But just imagining a 2m tall guy with two demon arms stopping the fight to hug and cuddle a puppy is ''hilarious''.
** Don't forget Aaroniero, who can't use his shapeshifting when in sunlight.

[[folder:ComicBooks]]
* What is every superhero and supervillain's weakness, no matter how powerful they are? [[spoiler: An eraser!]]
** {{Rimshot}}
* In ''{{Invincible}}'', The Green Ghost (a pastiche of GreenLantern) gets his powers by swallowing an artifact. When he wants to get out of costume he has to, err, regurgitate it.
* Almost every GreenLantern from the SilverAge onward had yellow as his main weakness. Any criminal could waltz past him by wearing a yellow suit and stealing only gold, and shoot yellow painted bullets from gold plated guns.
** Interestingly enough, this old weakness was referenced by the Kyle Rayner version of Green Lantern as being the unfortunate consequence of a programming bug- which, given the nature of real-world programming bugs, makes perfect sense. It turned out he was wrong, but hey -- it was a pretty good guess.
*** It was, however, [[SealedEvilInACan a]] ''[[SealedEvilInACan literal]]'' [[SealedEvilInACan bug. Of sorts.]]
** More recently, Frank Miller parodied the ''hell'' out of this in ''All-Star Batman and Robin''. Before confronting Green Lantern, Batman and Robin paint an entire house, and everything in it, yellow. Then they put on yellow costumes. Then they paint their exposed faces yellow. When GL comes over, Batman goes so far as to offer him a nice refreshing glass of lemonade, while Robin eats some lemon ice cream. Hal was not amused. Readers were.
** The original Green Lantern was almost as bad -- his weakness was wood(Referenced on TheBigBangTheory after a dismissive mention of the yellow weakness. The response? 'So either way he can be defeated with a number 2 pencil?'). Since so few people knew it as later Green Lanterns became famous, however, he in many cases seemed ''more'' powerful than the new Green Lanterns because, for example, the Sinestro Corps power rings couldn't even make him flinch.
*** This was parodied in the ''JusticeLeague'' GoldenAge AffectionateParody episode "Legends", with his [[CaptainErsatz stand-in version]] "Green Guardsman", who had a weakness to aluminum. Either way, you've got a superhero who could appear on the news after having been beaten to death with a baseball bat -- and considering that one of his foes was the Sportsmaster, who ''did'' wield a baseball bat... it's pretty darned weaksauce.
*** It didn't hurt that wood, while very common when Alan Scott first hit the scene, had become rarer in civilization by the time the SilverAge hit. Villains in TheDCU tend to decorate in metal, plastic, and ZeeRust by then, which means even less to block that strange ring with.
*** The {{Elseworlds}} story ''Superman/Batman Generations'' [[HandWave handwaves]] the odd Green Lantern weaknesses by having the Guardians explain that all weaknesses are mentally-imposed. Alan was weak to wood because a thug surprised him with a baseball bat and he ''assumed'' the ring didn't work against wood, while Hal was told that the rings were ineffective against yellow and thus added the weakness himself. Kyle, who gets his ring without hearing the explanation, lacks any weaknesses. (This is not, to be clear, how it actually works in continuity.)
** One Green Lantern story subverts this, however. A yellow robot attacks the Justice League. GL responds by picking up mud from a nearby swamp and dropping it over the robot's body, completely coating it. With the yellow hidden, he quite easily rips it open.
*** [[FridgeLogic One wonders]] why he didn't do that all the time. If he got into the habit of carrying a bucket of paint it could solve all his problems...
**** Not quite. In an Elseworlds title Called ''Batman: In Darkest Knight'', Bruce Wayne becomes the Green Lantern. In it, he is assaulted by poisonous, yellow ''gas''. Of course, this being Batman ''and'' the green lantern, he just scoops up a barrier of dust instead.
** Hal had the Flash repaint some contraption Ted Kord in his pre-beetle days gave them so it happened occasionally.
** He could still pick up a red painted car and drop it on the yellow clad villain. Doesn't have to actually touch yellow at all.
** The yellow weakness was especially weaksauce in the SilverAge because of the fact that every other villain seemed to emit some kind of "infra-yellow radiation", contain a "yellow compound", be surrounded by "invisible yellow" or have some other completely ridiculous piece of pseudoscience in place to stop Green Lantern destroying them in five seconds flat.
*** For those curious: "infra-yellow", in a sane world, translates as ''orange''.

*** But how could something be both invisible, and yellow?
****Or it could refer to a frequency of light that falls in the range of frequencies associated with the color yellow, but which is invisible because the human eye isn't set upt to detect it.
**** By the magic of the SilverAge.
** One of the ways to tell a veteran superhero from a rookie is that the vet knows how to get around their weakness.
** And then there's the Blue Lanterns, who are incredibly powerful even by Green Lantern standards, but can't use anything but the bare minimum of their powers unless a Green Lantern is in the vicinity.
** The all-multiverse champion of weaksauce yellow weaknesses is the BizarroUniverse Green Lantern, Yellow Lantern. As the name implies, he has a power ring that's like Green Lantern's, only yellow. ''Exactly'' like Green Lantern's. Including the part where it's powerless to affect anything yellow. That makes it powerless ''all the time''.
* One version of Ocean Master, {{Aquaman}}'s arch nemesis, gets his powers from a magical trident he traded his soul for, and when he isn't holding it he feels intense pain. Even the Joker says that this is a pretty WeaksauceWeakness.
* PowerGirl went through a single-issue DorkAge where she could be hurt by any "natural, unprocessed material", including the proverbial sticks and stones. This for a character who's on par with Superman. The negative reaction from readers caused it to [[CanonDisContinuity never appear again]]. It was just that weak.
** During her JLE days she was also allergic to diet soda, causing fits of anger.
*** That's a perfectly normal reaction for any intelligent being who's been given diet soda.
* ''{{Empowered}}'' is a self-admitted FanService exploration of this. The main character is a curvy babe who derives her powers from an [[ClothesMakeTheSuperman extremely skintight suit]], that's [[ClothingDamage laughably easy to rip]] and weakens her powers when damaged. Her tendency to end up naked (or nearly so) makes her the laughing stock of the local superhero community. Her tendency to get BoundAndGagged while doing so makes her living FetishFuel.
** The suit's ability to be torn seems to fluctuate with Empowered's confidence level. Since she has ''zero'' self-confidence anyway and the regular humiliations related to her crappy suit only compound them, it is ''very'' rare that she has the confidence to use her powers properly. But when she does, she's a one-woman army.
* The Daxamites in the DCUniverse are almost exactly like Kryptonians when under a yellow sun. However, exposure to lead is fatal to them, even in trace amounts. A notable instance of this example was when one of Superman's recurrent enemies/reluctant allies, Paragon, took out three Daxamites ''with a machine gun''.
* MartianManhunter has a ridiculous amount of powers, yet he [[strike:has]] had weakness to fire, making it quite easy to disable him.
** The first attempt to remove this weakness accidentally unlocked his {{superpowered evil side}}.
*** Future M'gann M'orzz has some kind of suit to block this weakness. She also happens to be evil, but this Troper is unsure if it is related.
** Elaborate explanations have been concocted over the years to explain ''why'' he is vulnerable to fire, but these seem needless. In RealLife, Mars is danged ''cold.'' Why ''wouldn't'' he be vulnerable to extreme heat?
* Prism, a member of the ''X-Men'' villain group the Marauders, is a truly pitiful example that combines this trope with WhatKindOfLamePowerIsHeartAnyway. His mutant ability is that he is made of a crystal that can absorb and redirect light energy (like a prism) and is no more durable than glass. Yes, he is made of ''glass''. His weaknesses include any sort of impact. Two of his four deaths (yes, he has died often) involve being thrown into a wall and being shattered by bullets.
* The greater the power, the weaker the sauce! Marvel's latest and most prominent Superman [[CaptainErsatz pastiche]] is the Sentry, a "golden guardian of good" who's pretty much as powerful as he lets himself be. But if you so much as ''remind him'' of his little DarkSide problem, he'll fly off to Saturn and cry. Or revert to human form. Or, if he's ''really'' unlucky, let the Void out -- and suddenly things will look a whole lot better for the bad guys.
* This was once parodied in the British comic, the ''Beano'', in which the character Calamity James is rescued by a superhero and offers him a Jelly Baby by way of thanks. Guess what the hero's one weakness is!
* Mr. Mxyzptlk is [[RealityWarper so powerful]] that he has no natural weaknesses. To make his fights with {{Superman}} more challenging, he gives himself one. Which one does he choose? Saying his own name backwards.
** [[CrowningMomentOfFunny Used hilariously]] in the animated series, with an entire episode consisting of Superman using clever and creative ways of exploiting Mr. Mxyzptlk's "weakness", often without having to use any sort of super powers at all.
* [[SpiderMan Venom]]. Weaknesses? Fire and loud noise. At one point, he's defeated with nothing more than a ''lighter''. This, of course, varies DependingOnTheWriter. Carnage shares some of the same weaknesses.
** Fan-favorite (yet sadly not used, ever) Toxin, Carnage's "child" however doesn't, what it does have is being very child like, (one point it refused to help it's host because he yelled at it)
* [[MarvelUniverse Marvel's]] Inhumans, genetic superhumans who have advanced technology and a civilization predating ''regular'' humans' by millenia, are done in by... pollution and germs.
* Dr. Doom, Deadpool, and Thanos ''all'' have a weakness to squirrels - considering that Squirrel Girl has hammered all of them at one time or another.
** One could argue that Deadpool's biggest weakness is, of course, his own brain.
* ''TheDarkness'', phenomenal [[EldritchAbomination cosmic/demonic power]]. But can’t operate under a 60 Watt light bulb.
* [[DCUniverse DC Comics]] also had Firestorm, whose weakness is organic materials. Like, all of them. He can't affect them with his power, or he'll suffer painful consequences. So...he could be foiled by a stick. Or a leather wallet.
** True, but he could still in theory turn all the air (which isn't organic) around his stick-wielding opponent into iron or something. He doesn't do this, though, because his power is really hard to use.
*** A recent version of Firestorm gets his behind beaten ... not because of his inabillity to manipulate the surrounding enviorment. Batman praises this, which means you know it's skilled. Anywho, Firestorm got beaten because he published a scientific paper on how his own powers worked. And Lex Luthor read it. Oh noes indeed. Oh yeah, he needs to merge with someone to be Firestorm and if the merge happens too long, his own powers -eat- his partner. Nom nom nom.
** In one of his appearances on ''SuperFriends'', he was rendered helpless after being sprayed with ''plant food''. Even ''their'' version of Aquaman wasn't as lame.
* Although it's since been removed, Eclipso - DC's god of darkness - could be dispelled from his human host by a camera flash.

[[folder:{{Film}}s]]
* The aliens in ''{{Signs}}''. It's [[NightmareRetardant hard to feel threatened]] (retrospectively) by creatures which will dissolve in an April shower or corrode in a particularly humid breeze.
** In Shyamalan's earlier film, ''Unbreakable'', he also used water as a weakness for the main character. In that case, though, it wasn't that he was vulnerable to water, but rather he was just as susceptible to drowning as a normal person. If he drank something too quickly he would choke and if he was submerged he would succumb to drowning just like everyone else.
*** Well, and it was theorized that the dense bone and muscle that made him ''unbreakable'' also made him ''unfloatable''.
** He probably got the idea from ''Invasion of the Saucer Men'', whose aliens were melted by ''light''. There is nothing lamer.
*** The monsters of ''PitchBlack'' had a similar weakness to light. Though this actually worked, as most of the movie was during a solar eclipse and they broke their flashlights.
*** Same thing in ''AttackOfTheTheEyeCreatures''. Although, in this case, it was more because TheyJustDidntCare.
*** Also ''TheMolePeople''; the lost colony of ancient Sumerians living BeneathTheEarth had adapted to their lightless conditions to the point where our heroes could kill them with a ''flashlight''.
** In the movie version of ''TheDayOfTheTriffids'', the titular monsters were melted by sea water. Nearly as lame. (In the original novel, ironically, flame-throwers are among the most effective anti-Triffid weapons.)
* The Tenctonese in ''AlienNation'' (the movie as well as the series) are harmed by ''salt water''. Seawater is like acid to them. And they live mostly on the Californian coast.
* The aliens in ''TheWarOfTheWorlds'' were killed by [[spoiler:a common disease]]. [[JustifiedTrope Justifiable]], as long as the aliens are [[PlotInducedStupidity particularly stupid]], but still lame to death. Literally. [[spoiler: An advanced civilisation that had eliminated all diseases locally would hardly go a new biosphere without guarding against new diseases there, especially if they knew in advance that they were going to have to 'drink the water' once they were there.]]
** Justified in H.G. Wells' novel in that [[spoiler:the aliens were so advanced and germophobic that they wiped out all microbial life on their native planet. Which of course meant they had nothing to develop immunities to when they invaded Earth]].
*** Meaning that H.G. Wells is either a genius or incredibly prophetic, as [[spoiler:that same germophobia and extermination of microbes on our planet has actually resulted in many people having weaker immune systems, so that when they ''do'' become infected they're at a greater risk]] (spoilered because it relates to the above spoilers).
**** It's called common sense. [[spoiler:Being dirty builds character, and immunity. And perhaps a legion of old purist ladies wanting to beat you up, if you take the "dirty" advice the other way around.]]
**** It's still a [[YouFailBiologyForever failure]], given that [[spoiler: microbes]] from Earth should be unable to [[spoiler: infect an alien, who presumably has a radically different physiology than the one the microbes have evolved to infect]]. For the same reason, a human can't get [[spoiler: plant diseases]] (indeed, [[spoiler: most diseases]] are unable to [[spoiler: jump species]], specially if they are so different).
***** Actually, [[spoiler: many diseases do jump between species (plague, anyone?). Usually, viruses that make this jump are far more lethal to its new, suboptimal host.]]
***** Well, [[spoiler: a virus jumping to an alien host]] is highly unlikely, since a [[spoiler: virus depends on hijacking a specific fragment of a cell's DNA to reproduce; the DNA of an an alien cell, if it even ''has'' DNA at all,]] will be so different from anything on Earth that hijacking it is impossible. However, there's plenty of [[spoiler: yeasts, bacteria and fungi]] that can [[spoiler: reproduce]] on their own so long as they're in the right environment. They [[spoiler: [[http://www.physorg.com/news142764167.html also are less shy about the species barrier]]]]; so long as the aliens are similar to some kind of lifeform on earth (and why would they invade if they weren't?) it wouldn't be surprising to [[spoiler: see a jump]].
**** Even if the Martians [[spoiler: weren't suitable hosts for viral replication, they're still organic life forms. Bacteria could still ''decompose'' their defenseless tissues, even if no microorganism was specifically adapted to parasitize Martians. Indeed, decaying from within is pretty much how the book describes their slow demise.]]
**** They were surviving by getting transfusions of human blood. I think we can ignore standard bio-chemical barriers after that revelation in the book...
** None of which even really matters, as the original story is true. [[spoiler: It's an allegory for malaria and why Africa wasn't conquered earlier. Which actually makes it pretty scary--when the aliens have finally managed to survive our diseases, they'll be able to come back and take over our planet.]]
* In the Disney Channel movie ''Up, Up, and Away'', the weakness of the superhero family is aluminum foil.
* In ''SYNGENOR'', the titular creatures were created to be the perfect soldiers for a war with the Middle East. They don't need to eat or sleep, are immune to most weaponry, and reproduce every twenty-four hours. Their only weakness? Water is like acid to them. It's somewhat hard to be afraid of a super soldier that can be defeated with a super soaker. Or, if worst came to worst, by peeing on them.
** Of course, water is in rather short supply in most of the Middle East. Still, it's pretty stupid to design a soldier who is only usable in particularly dry environments.
* In the Dead Gentlemen Productions (of ''The Gamers'' fame) running ''Demon Hunters'' series, Duamerthrax the Indestructible is a walking brick that is, well, all but indestructible. He's an "earthwalker", a demon said to have been kicked out of hell for being ''too mean''. Unlike other monsters and demons in the mythos, he's not susceptible to ordinary injury. He can literally eat the round of a large-caliber revolver jammed in his mouth ("Mmm! Nice 'n' leady!") casually regrows limbs after being dismembered, and generally shrugs off what few injuries he even takes while making terrible puns. So what's the convenient balance? We're told that every earthwalker has a weakness to some substance, "a plant, metal, anything". Duamerthrax's turns out to be ''mint''. Being shot repeatedly at close range with numerous handguns does little more than inconvenience him, but the breath of someone having just used breath spray causes him intense pain, water-guns full of mouthwash can inflict serious harm and [[spoiler:mint dental floss can do even worse things]].
** This troper thinks it's a reference to [[NorseMythology Baldr]]
*** Though wasn't Baldr's weakness mistletoe? (Which, incidentally, still fits this trope pretty nicely...)
* ''MarsAttacks!''. The Martians' weakness is hearing the song "Indian Love Call" by Slim Whitman, which [[YourHeadAsplode causes their heads to explode]].
** One unanswered question is whether any other Slim Whitman song would have had the same effect.
*** They probably would've had the same luck with any song involving yodeling, since it was at that moment in the song that the head trauma occurred.
* The Tomatoes in ''AttackOfTheKillerTomatoes'' had the same weakness, in the form of a song called "Puberty Love".
* Imhotep in ''TheMummyTrilogy'' will immediately be chased away when a cat is in his presence. Naturally, the heroes only used this to their advantage once instead of surrounding themselves with as many cats as they could gather and easily trouncing him.
**The cats wouldn't have stopped his army of mooks in the first and second film. And one of the characters mention that it would stop working once he fully regenerated.
*** It's not so much that the cat does anything, but that Ihmotep is a superstitious Egyptian. He is afraid of cats due to their religious significance and hasn't realized they can't actually do anything to him.
*** It is a major FridgeLogic moment why they didn't use cats. Believe it or not, in RealLife an [[http://en.wikipedia.org/wiki/Battle_of_Pelusium_(525_BC) invading army conquered Egypt by using Egypt's superstitions about cats]].
** Probably because, according to Diodorus Siculus, "[[http://www.richeast.org/htwm/cats/cats.html Whoever kills a cat in Egypt is condemned to death, whether he committed this crime deliberately or not. The people gather and kill him. An unfortunate Roman, who accidentally killed a cat, could not be saved, either by King Ptolemy of Egypt or by the fear which Rome inspired]]"
* From 1966 superhero parody ''RatPfinkABooBoo'': "Remember, Boo Boo, we have only one weakness... bullets."
* Like the Dalek example given below, in the 1987 movie {{Robocop}}, the killer robot ED-209 chasing the titular character was taken out of play simply by trying to chase RoboCop down stairs too narrow for its massive feet.
* In an {{Homage}} to ''TheWizardOfOz'', Death in ''SixStringSamurai'' is killed when squirted with water.
* Derek {{Zoolander}} can't turn left until his BigDamnHeroes moment. (Though continuity nitpicks will note that he does turn left (relative to himself, though not the camera) while in disguise while trying to retrieve Maury's computer.)
* The most literal Weaksauce Weakness must be in ''TheSpiderwickChronicles''. Tomato sauce is corrosive to goblins. (Was this taken from the book?)
* [[YellowSubmarine The Blue Meanies]] are repelled by positivity in any form. This doesn't work out so badly, though, since their entire arsenal is built around the proliferation of depression and despair, but it does still leave them vulnerable to [[ThePowerOfRock music]].
* {{Bolt}}, of the movie of the same name, ''thought'' his super-weakness was styrofoam.
** That said, he didn't actually have any powers to begin with.
* {{Mystery Men}}, Invisible Boy's weakness was anybody looking at him while he was invisible. (Machines, like motion detectors couldn't see him.)
* The SuperCop in ''Super Fuzz'' has super speed, super strength, invulnerability, telekinesis and so on, but he completely loses his powers when he sees the color red (probably a nod to GL and his vulnerability to yellow): a red traffic light, a red flower, a red ribbon, and he's harmless.
[[/folder]]

[[folder:{{Gamebook}}s]]
* The Darklords of the ''LoneWolf'' gamebooks are [[spoiler:(were, as of Book 12)]] crippled by ''clean air'' and can only unleash their full strength in toxic habitats; making them the polar opposite of CaptainPlanet. Half the reason they waged a centuries long campaign ruining Magnamund (the other half being that they are AlwaysChaoticEvil embodiments of evil) is [[spoiler:(was)]] to make the world a paradise for themselves. It should be noted that even in their weakened state they can still put up a good fight with their mastery of BlackMagic and immunity to conventional weapons.
[[/folder]]

[[folder:{{Literature}}]]
* The Wicked Witch of the West from the ''TheWizardOfOz'' was done in by a pail of water. This was explained in the book (but not in the movie) as due to her "dried up by years of evil" but no indication was ever given that water would kill her. The book does mention that the Witch would never go near Dorothy when she bathed because she hated water.
** This troper likes to play with the explanation that "dried up by years of evil" means that she's practically mummyfied, and mummies don't last long when wet.
** This makes said Witch ''giving'' Dorothy a bucket of water to do chores with a rather stupid move. Though the fact that the movie is made AllJustADream allows for a convenient HandWave.
** Spoofed in the ''EnchantedForestChronicles'', where evil wizards can be melted -- but only with soap and lemon juice added. The good witch Morwen, on the other hand, explicitly does not melt. It is later theorized that this might be because the wizards never shower while Morwen is something of a neat-freak.
*** Eventually, the heroes refined this into a one word spell with the same effect. One very memorable word, too: [[spoiler: Arglefraster]]!
** The book ''Wicked'' explores it to its entirety, explaining that since birth the water hurt her, so she had to clean herself with oil and find creative solutions for things which normally involve using water. When she cries, it's like acid flowing down her face.
*** Meanwhile, TheMusical ''{{Wicked}}'' openly mocks the entire idea of water melting the Witch. [[spoiler:Elphaba uses this urban legend about herself to fake her own death at Dorothy's hands.]]
*** It seems though that it can only hurt her if she is immersed in it. This Troper recalls a part in the book where she is drinking coffee, and is described as being ''very'' careful to get it nowhere other than down her throat. Weakness to water could be the result of the unexplored concept of being "a daughter of the dragon". Its also implied that if Elphaba had ever come into the fullness of her powers, water would cease to be a true threat to her (at one point she instinctually freezes a lake, allowing her to cross it unharmed).
** Another Oz-related Weaksauce: the Nome King was an extremely powerful, nigh-invicible subterranean fairy who had armies of nomes... all of them, including him, could be weakened to the point of being killed by ''eggs''. This doesn't look as bad as it seems at first, because there's only one chicken in Oz.
** In ''Cheshire Crossing'' (a webcomic by the creators of ''CaseyAndAndy''), the WickedWitch of the West explains that ''all'' witches are vulnerable to water (while in Oz, at least) -- she was keeping the water on hand should Glinda the Good Witch launch a surprise attack. (In a later scene, the bucket is labeled "In case of Glinda".) She just never expected her enemy to bully a little girl into doing the deed.
** And in ''[[DarthsAndDroids Magicians & Munchkins]]'', she simply [[http://www.darthsanddroids.net/magiciansandmunchkins/episodes/0050.html took this disadvantage]] to get a few additional levels in magic.
* The Martians, in RayBradbury's ''The Martian Chronicles'', are killed ''en masse'' rather early in the book by a human-induced plague of chicken pox.
** Which is in itself taken from ''War of the Worlds''.
** It's also a ShoutOut to American history.
* The Boggart in ''HarryPotter and the Prisoner of Azkaban'' seems to be almost an incarnation of this trope. A Boggart will materialize in the form of a person's worst fear (though exactly what that means is debatable). The way to repel one is to forcibly imagine the fearsome thing as something ridiculous, and then laugh at it.
** Depending on the victim, this is easier said than done. One notable example is Molly Weasley's worst fear: [[spoiler: seeing the dead bodies of her children, a fear that comes true in Deathly Hallows with the death of Fred]]. It's hard to see how ''that'' could be imagined as something ridiculous.
*** Strictly she feared [[spoiler:losing the people she loved in Voldemort War 2]], which was understandable given what the last two wizarding wars had done to the wizarding community in general and more specifically to her. She lost both her brothers, who died in service to the Order. Still, it is a hard fear to subvert -- turn it into one of the twins practical jokes perhaps? That's why Lupin advised his students not to face a boggart alone.
*** Well, the Boggart's other WeaksauceWeakness is [[{{Disgaea}} its inability]] [[TooDumbToLive to think]]. Remember the "half a slug" incident?
** Voldemort's inability to understand Love, and ThePowerOfLove, proves to be his ultimate undoing.
* Eddings' ''TheRedemptionOfAlthalus'' featured both one protagonistic and one antagonistic FiveManBand, both with similar power arrays. The villains included the evil mind-leech Koman, with telepathy and mind-warping abilities... who was defeated when Althalus thought about random numbers.
** ''Fractions'' of numbers, even.
* The Auditors in ''Science of {{Discworld}} III: Darwin's Watch''. There are very logical and clearly worked out reasons why chocolate kills them in ''Thief of Time'', due to some peculiar circumstances. In ''[=SoDIII=]'', though. it just ''does''.
** ''Incarnated'' Auditors, that is. Not even Death could harm their incorporeal "robes" form -- if they bother to present themselves at all.
** But the non-incarnated Auditors can be killed by getting them to say "I", "me", or otherwise admit individuality. Since it's widely known that (a) only living things have individuality, (b) all living things die after some amount of time and (c) any living thing's lifespan is practically no time at all compared to the universe's, any Auditor who admits individuality instantly dies.
*** Though by the perspective of the rest of them, this isn't much of a loss, since there are more Auditors than there is ''anything else in the universe'' and, by definition, any given one of them is supposed to lack any defining characteristics.
* In ''ArtemisFowl'', fairy magic can be completely stopped by animal fat. That's right, magic that can make you invisible, hypnotize people, heal nearly anything, and in some cases ''travel through time'' can be stopped by ''lard''. Fear the lard!
** The lard works in mysterious ways.
** Oh dear lard.
*** Since humans are animals, does this makes fatties immune to fairy magic? If so, would fat fairies be useless? My head spins, thinking too much might be ''my'' Weaksauce Weakness.
*** No, that's just the aftereffect of the [[IncrediblyLamePun dreadful puns]].
*** That's the [[http://www.youtube.com/watch?v=Ry0TyIJXgoU Power of Lard!]]
* ''The Haunter in the Dark'', the titular monster in a story by HPLovecraft is an avatar of the god Nyarlatothep. It's a huge winged and tentacled mass of darkness with a three-lobed burning eye, whose touch will burn the flesh from your bones. However, it's extremely vulnerable to light. Even little light will hurt it, and strong light will banish it. So you can [[DidYouJustPunchOutCthulhu defeat an avatar of an ancient and evil god]] with ''a flashlight!''.
** Only this particular avatar - it came from another universe where there is no light - in there it is undoubtedly unstoppable, and even in our world it's unkillable.
*** Of course the author of the Cthulhu Mythos/[[{{NeonGenesisEvangelion}} Evangelion]] crossover fanfic ''Children of an Elder God'' completely failed to take such meager issues to account, when he decided to have this avatar attempt to fight the Evangelions - after a human-avatar ''deliberately'' changed to this form. Now ''that's'' lame.
** It's worth mentioning that the Haunter apparently is quite capable of tracking down its victim with ease once it does decide to get moving and is incredibly patient. (In the story, it basically waits for a chance to sally forth from its hiding place for ''three months''.) So in the absence of other light sources, that flashlight is only as good as its batteries...
*** Exactly. You can't defeat it, only drive it off. And it's immortal, and patient, ''and it will never stop coming for you.'' Someday, somewhere, you'll be in the dark, and ''it will be there, waiting.''
* In ''Worldwar'', the invading reptilian aliens called 'The Race' had an immense weakness to ... ginger. Not only was it an incredibly addictive narcotic, but it also made the females produce sexual pheromones outside of the normal fertility cycles, turning exposed members of The Race into crackheaded sex fiends. When the humans attacked Race-occupied Australia, they used missles armed with warheads ''packed with powdered ginger''.
*In L.J. Smith's ''Night of the Solstice'' series the Fair Folk-like race known as the Quislai have many advantages, such as immortality, invulnerability, extreme beauty, the ability to throw lightning bolts, the power to travel to places quickly using secret pathways through space, and freedom from nearly all physical limitations. They can't be imprisoned by normal means, as doors and windows will unlock themselves for Quislai, and they can travel through dimensional gateways between worlds without preparation while everyone else requires a special magical amulet to use them. However, the one thing that can restrain them is a thornbranch tangled in the hair. Unfortunately, most Quislai seem too ditzy to think of cutting their hair short or at least avoiding rosebushes.
* From ''TheBible'': "And the Lord was with Judah, and he drave out the inhabitants of the mountain, but could not drive out the inhabitants of the valley, because they had chariots of iron." No, really. The Lord is helpless against '''iron'''.
* The DeathWorld creatures of ''Fragment'' are averse to salt water and avoid it (it's toxic to them for some reason), which is presumably what's kept them confined to Henders Isle. This is discovered accidentally by a lucky fool who blunders into a saltwater pool while fleeing the orgy of death chasing him, and is later adapted as a defensive measure against Henders creatures.
[[/folder]]

[[folder:LiveActionTV]]
* ''DoctorWho'' is renowned for ending its episodes either by [[ReversePolarity Reversing The Polarity]] or exploiting the latest {{Monster Of The Week}}'s Weaksause Weakness. The most famous example is the Cybermen and their allergy to gold, which eventually lead to ''Silver Nemesis'' and the hilarious scene of Cybermen being stopped by gold coins and a slingshot. At the time a popular joke was that in their next appearance, just saying the word "gold" to one would kill it. This was quietly ignored in more recent episodes, since those Cybermen came from an AlternateHistory (though a ContinuityNod was made in a tie-in website which stated that said AlternateHistory Cybermen did initially have an "allergy" to gold, but it was eliminated by R&D).
** "Image of the Fendahl" had the monsters defeated by ''rock salt''.
** Originally, a Dalek could be defeated by a flight of stairs, obscuring its rather obvious eyestalk, or simply pushing it over. Over time, they became far more credible foes. Their third appearance showed them no longer being limited to ground level. The "can't climb stairs" thing was done away with in 1988's "Remembrance of the Daleks" (much to the Doctor's horror). In the new series, they can not only hover but swoop around like crazy, remove foreign substances from their eyestalk lens (much to Wilfred's chagrin), and ''incinerate humans on touch''.
** The Slitheen, due to their bodies consisting mostly of calcium, messily explode if acetic acid comes into contact with their skin, no matter how little. Cue the squirt guns filled with vinegar.
** "The Fires Of Pompeii" has the Doctor fighting seven-foot rock beasts with a water pistol... and winning.
** "Blink" has creatures that can, when noone's looking, move faster than Jack Harkness confronted with a twelve-step program. When seen, however, they can't move. The episode plays this up for high-grade NightmareFuel, as you have to blink ''sometime''...
** When an episode of ''{{Extras}}'' featured the filming of a mock ''DoctorWho'' episode, this very trend was parodied with a giant slug who was vulnerable to table salt - which he conveniently kept on his desk, just within reach of the Doctor.
*** Actually, in Colin Baker's first serial, ''The Twin Dilemma'', the Doctor really ''does'' fight a giant slug.
** The real WeaksauceWeakness of the Daleks is ''the Doctor himself''. His knack for improvising DeusExMachina solutions and general unpredictability really freaks out the Daleks. Doesn't matter if it's four or four ''million'' Daleks. The Doctor, with a bit of help, ''will'' eventually kill them all. [[JokerImmunity Again and again and again]].
* Sylar of ''Series/{{Heroes}}'' could be reduced to a writhing, quivering lump with the use of a ''tuning fork'' after acquiring Dale's super hearing (though Dale was the same way).
** Similarly Elle possesses powerful electrical powers, but because of them can be incapacitated by a bucket of water, which shorts the circuit and fries her with her own powers.
*** Which makes one wonder how she showered or bathed. Now if you'll excuse me, ThisTroper intends to spend a great deal of time picturing Kristen Bell in the shower to contemplate this problem.
* The [[StarTrekTheOriginalSeries classic]] ''StarTrek'' episode "Day of the Dove" features an [[EnergyBeings Energy Being]] which feeds on negative emotions, and so causes total chaos on the Enterprise by provoking conflict in order to feed on it. Kirk eventually figures out that the alien can be driven off by ''peace''.
* In ''{{Smallville}}'', Aquaman's guest appearance explained that he needed to be constantly wet or otherwise have a glass of water or he looses his immense strength and begins to wither. Considering he has had plenty of his own [[WhatKindOfLamePowerIsHeartAnyway superpowered problems]], this is especially glaring.
** Don't the writers of ''{{Smallville}}'' know that Kansas is ''landlocked''?
** In the show, Kryptonite is so common that Clark would almost be better off powerless. Especially problematic in the earlier years when his "monsters of the week" got their powers FROM kryptonite.
** This one is somewhat justifiable early on in that this is the one town in the world to be hit with what appears to a be a rather large amount of kryptonite, making it "rare" in the sense that, globally, it isn't a significantly occurring mineral, but in smallville it's all over the place and is even a trademark of the town.
* On ''AllThat'', the character Superdude... is lactose-intolerant. Even throwing milk ''on'' him will send him to the ground, disabled. So of course, the bulk of his rogues' gallery is dairy-related: Butter Boy, Yo-Girl, Cow-Boy, the Dairy Godfather, & his ArchNemesis Milkman. [[spoiler:His one foe without quick access to lactose, the Evil Superdude, gets a NiceJobBreakingItHero moment when confused bystanders use a pitcher of milk to tell the two apart.]]
* In the '80s series ''{{V}}'', aliens are vulnerable to certain inoffensive bacteria that live in human digestive tract. [[spoiler:It backfires later on.]]
** Oh my god... so... they'd be vulnerable to poop?
** Ironically, humans are also vulnerable to these bacteria (E. coli, anybody?) making this TruthInTelevision.
* The alien "Gua" in ''First Wave'' turn out to be badly affected by salt. It affects them roughly like heroin affects humans. One episode featured renegade Gua hiding out in a derelict building snorting packets of [=McDonald's=] salt. Of course, this is the same series where the hero fought the alien invasion using the lost diaries of Nostradamus, so...
* In an episode of ''StarTrekTheNextGeneration'', the crew deals with a hostile silicon based lifeform that draws its energy from light. They subdue it by turning the ship's interior lighting off.
* Sportacus, the superhero of {{Lazytown}} becomes helpless if he eats things with SUGAR, like candy. However it may be that he's actually weak to chemicals ''added'' to sugar, as he can eat (and in fact gets stronger) from eating FRUITS, which contain ''natural'' sugars.
* Turned on its head by [[BuffyTheVampireSlayer The Gentlemen]] who die instantly upon hearing a human voice. Because of this they just steal everyone's voice making them essentially invincible.

[[folder:TabletopGames]]
* In ''{{HeavyGear}}'' the advanced ''Black Mamba'' Gear - one of the more powerful designs in either of the two superowers' armies - had exceptionally weak rear armour. The result is that Black Mambas could be (and routinely were in gameplay) easily defeated by lightweight ''Cheetah'' scout Gears. While the fluff text initially ingored this, the game's designers eventually acknolwedged and lampshaded this weakenss by having Mamba pilots clamouring for a solution to the "glassback" problem.
* Just about every race in [[{{Warhammer40000}} Warhammer 40,000]] has this issue with at least one unit, usually being the same weakness of the army, such as:
** Space Marines: Vanguard - incredibly expensive, leading to low numbers
** Chaos Marines: Spawn - random and uncontrollable
** Eldar: Harlequins - tissue paper armor
*** Wraithguard and Wraithlord - Wraithsight, a 1/6 chance of being "blind" and unable to do anything; ''every single turn''.
** Orks: Nob Bikers - mediocre Leadership
** IG: Basilisk - very restrictive ''minimum'' range
** Necrons: Warriors - no upgrades
** Tyranids: Biovore - it's not a Carnifex
** Tau: Crisis Battlesuits - poor in combat
*** The Tau in general are effectively useless in close combat without Kroot allies.
** ...and so on.
* Most of the monsters in [[HeroSystem ''Lucha Libre Hero'']] take extra damage from ''lucha'' combat manuevers. And since the PCs are by default ''technico'' luchadors, there's a lot of these showing up in the fight scenes. But then, the sourcebook was inspired by Mexican ''lucha'' films, and "every problem can be solved with a good wrestling hold" was standard in those films.
* In {{GURPS}} the disadvantage Supersensitive makes having any other sort of sentient creature with 20 meters a serious weakness. With Combat Paralysis your greatest weakness is being put in any sort of danger. Naturally such disadvantages are not recommended for Player Characters.

* Razputin in ''Psychonauts'' cannot touch water because of a family curse (or just a bad case of hydrophobia).
* The biggest weakness of Metal Man from ''{{Megaman}} 2'' is his own weapon (which kills him in 1 hit!). Granted, Megaman can't take advantage of it during their first fight, but the token BossRush is a different story.
** Given the fact that the elemental weaknesses in that game are bizarrely messed up, and the fact that Megaman has 8 Metal Blades for every one bar of weapon energy (8 X 32 = 256 Metal Blades!), even enemies that ''aren't'' weak against Metal Blades tend to get pummeled by Metal Blades. That's not even saying anything about the multi-directional nature of the weapon, all of which basically adds up to the best Mega Man weapon ever devised. Later games in the series fixed that by making the weapons increasingly useless.
** Interestingly, most of the Robot Masters' weapons were like this; it only stopped come ''{{Megaman}} 7'', where not only would attacking them with their own weapons not do anything, it would actually ''power them up'' in some cases. (or at the least, make them laugh at you for trying something so illogical)
*** Freeze Man even breaks the FourthWall by staring at the player and freezing the game if you try to hit him with a Freeze Cracker.
** The final bosses of ''{{Megaman}} 2'', and ''{{Megaman}} 7'' can only be damaged with the most useless and most difficult-to-hit-with weapons(the Bubble Lead and the Wired Coil, respectively).
** The final form of Wily in ''{{Megaman}} 3'' can be one-shotted with a proper application of Top Spin, a glitchy and hard to aim attack that often damaged you and would drain the entire bar if mistimed.
** In ''MegamanX 1'' and ''2'', the final boss forms of Sigma were weak against the Rolling Shield (a hard to aim attack that generally did less damage than a charged shot) and the Strike Chain (a pathetically short ranged attack).
** Let's not forget Megaman's [[SpikesOfDoom severe intolerance to pointy things coming from the ground]].
** Arguably, any boss weak to any of the series' more questionable moves would qualify - such as ''MegaMan 5'' boss Wave Man, who was essentially vulnerable to being kicked.
* Don't even get us into how this applies to multiple-typed ''{{Pokemon}}''.
** In the original pokemon, Psychic types were generally overpowered. They only had one weakness: the laughably weak bugs.
*** [[GameBreaker Not that it mattered]], as there were only three damaging bug type moves: Leech Life (which is pathetically weak even at double damage), Twineedle (which is only learned by Beedrill), and Pin Missile (which was admittedly on the useful FragileSpeedster Jolteon, but sadly requiring its weaker attack stat). The fact that bugs are so pathetically weak actually makes this a ''subversion'': Most Bug types had abysmal stat and often had Poison as a second type, which made them weak to Psychic types anyway so they were useless even then.
** Poor Shedinja. Its ability, ''Wonder Guard'', is great (invulnerable to all move types but the ones it's weak against). But its typing (Bug/Ghost) gives it 5 weaknesses, including types that only an ''idiot'' would build a team without. That means it's only good against [=AI=] opponents that you know don't have those type moves (or any of the environment moves that will take it out too). Good luck leveling the poor guy.
**** That's not even the kicker. Shedinja has only ''one'' Hitpoint. This means that any attack that manages to connect will instantly knock it out.
**** Moreover, while it's invulnerable to direct damage moves, status ailments could affect it normally. Shedinja could simply be confused, and it would effectively commit suicide.
**** Coincidentally in the very same game, the near-almighty Kyogre would be generated most of the time with no powers that could hit Shedinja, letting the tiny bug cut him to DeathOfAThousandCuts.
***** Interestingly enough, in the various Pokemon battle game categories, Shedinja is an extremely viable option in the Legendary/Uber arena, in that most of the commonly used Legendary pokemon have no moves that can penetrate Wonder Guard, and if you can take out the 1 or 2(at most) pokemon that could beat Shedinja, you've practically assured yourself a victory.
** There's also Paras and Parasect, who in the first generation had ''three'' 4x weaknesses.
*** One of their new abilities in the fourth generation gives Parasect what is essentially a ''5''x weakness to Fire. Parasect also gets a 100% accuracy sleep move, which is potentially the most powerful status-inducing move in the game, so the WeaksauceWeakness was likely added to keep it from being a GameBreaker.
*** That and Parasect's speed, which is abysmal.
** Gyarados is a Water/Flying type. Hope your opponent's Pokemon aren't too [[IncrediblyLamePun shocking]].
*** And the electric type is half-composed of cute little rodents. So you have things like one foot tall squirrels and mice taking down a 21 foot long sea monster, known for destroying entire towns in fits of rage by the way, in one hit. And a grinning sphere, too, [[EarthBound but those are actually dangerous]].
** Several moves and other things introduced in the fourth generation of the games can cause examples of this trope. One of the most hilarious: a Grass-type move called Grass Knot that is said to work by tripping the opponent, and does more damage the heavier the opponent is. The result of this is that the heaviest Pokémon in existence, the Ground-type [[http://bulbapedia.bulbagarden.net/wiki/Groudon Groudon]], can often be ''tripped to death in one hit'' by something as small as a [[http://bulbapedia.bulbagarden.net/wiki/Pichu Pichu]].
* Somewhat in keeping with the game's theme, the BigBad of ''{{Spore}}'', [[spoiler: the Grox]], is weak against... Life! They can only survive on barren planets; creating a life-sustaining world literally kills them (although their spaceships can still bomb you from orbit).
* [[NobleDemon Laharl]] in ''{{Disgaea}},'' being a young demon who makes a big deal out of being evil, is violently allergic to women with sexy bodies and expressions of optimism or hope. In one battle he has to fight a bunch of half-naked [[HornyDevils succubi]] and [[CatGirl nekomata]] with his stats halved; another time [[LoveFreak Flonne]] nearly kills him by yelling "eternal love!" (her favourite words).
* In ''EliteBeatAgents'', an alien species known as the "Rhombulans" come to Earth and ban music because they're scared of it. Then the agents come and get everybody in the world to dance to Hoobastank and the Rolling Stones.
** To be fair, anyone who wouldn't instinctively dance to a worldwide concert of Jumpin' Jack Flash probably has no soul.
* Sonic in the ''{{Sonic the Hedgehog}}'' franchise is extremely weak to water. Not only can he not swim, he also moves at an extremely slow pace when under. In the anime ''{{Sonic X}}'' he can't even move while underwater, and he can't move while on ice. There was an entire episode of ''Sonic Underground'' and ''Sonic X'' devoted to Sonic's aquaphobia. Also, in ''Mario and Sonic at the Olympic Games'' Sonic wears a life vest whenever he participates in a swimming event.
* The final boss of ''FinalFantasyTactics'', [[spoiler: St. Ajora]], is incredibly weak to [[spoiler: the Oracle spells of Drain and Osmose, the two easiest spells to acquire for the class]], and the AI even actively hones in on characters using it [[spoiler: by outright killing them if able, or depleting all their magic if not]]. However, even a single Chemist is enough to counter these effects, and you can merely have the rest of the party wail on the final boss without it even bothering them for an easy victory.
** It should be noted that due to the mechanics of [[spoiler: Drain]] it kills any unit in the game in 4 hits. However, this is not very useful against most of the units in the game since you can probably 1-3 shot them. However, using it against Zodiac bosses, and especially the last boss, is quite effective since 4 shotting them is probably about the best you can do anyway.
*All three final bosses of the Mother series. All three are established as ridiculously powerful, perhaps even immortal, up until the final fight. [[spoiler: Giegue/Giygas from Mother is forced to retreat because of the emotions of song, Giegue/Giygas from Mother 2 dies from the prayers of a little girl combined with the hope of everybody on Earth alongside the player, and Claus/Masked Man from Mother 3 dies by killing himself due to brotherly love.]] Although, admittedly, their weaknesses were the entire point of the fights themselves.
** Then again, you have to admit that having a final boss die [[spoiler: as a direct result of the player wanting it to]] is a pretty awesome approach.
* Almost a literal version: In BaldursGate II, the extremely powerful liches rely entirely on magic in combat. There is a relatively low-level spell that allows you to polymorph into a 100% magic-immune and thus undamageable-by-liches creature: The Terrifying Mustard Jelly. GameBreaker ensues.
* Cole from ''[=inFamous=]'' has the standard "electric super" Weaksauce Weakness of water... but also has one in chain-link fences. The metallic mesh absorbs his shots and dissipates them harmlessly. He has to go around to shoot whatever is on the other side -- since every last chain link fence in the game is capped with razor wire and can't be climbed. [[http://www.penny-arcade.com/comic/2009/5/27/ Penny Arcade didn't let this go without comment.]]
* In ''{{Prototype}}'', Alex Mercer and the Infected have a Weaksauce Weakness in water. Their biomass is too dense to float. Alex and Hunters will just jump back out of any body of water they falls into after a brief pause. The Infected [[SuperDrowningSkills not so much.]] However, it takes place on Manhattan Island, so besides the surrounding water that makes it an island, there's not a lot of water to use. Makes the quarantine easier to keep, though.
* Using [[UselessUsefulSpell Provoke]] on Defender X in FinalFantasyX will force him to use an attack that halves the target's current [=HP=] for the remainder of the fight (unless the Provoker switches out of battle). Therefore, the fight becomes a ForegoneVictory.
** Many other bosses have some exploitable weakness (some more obscure than others), making a "level one" run easier than you might expect.
* ''{{Okami}}'' monsters can have some pretty weaksauce weaknesses:
** The "Bloom" technique, that causes flowers to sprout from trees, will also open bud-based enemies and reveal their weak point.
** Umbrella-weilding and flying enemies are weak to "Galestorm" which most of the time isn't any more powerful than a moderate breeze.
** The Tengu can be calmed down from going berzerk by causing it to rain.
** The BigBad is weak to [[spoiler: sunlight]], but then again, [[spoiler: he ''is'' a god of Darkness]].
** Amaterasu herself is weak against cursed zones, which are super-dark areas of both physical and spiritual pollution. (Maybe she's related to CaptainPlanet?)
*** Considering those zones petrify normal humans on contact, this isn't weaksauce at all. She is merely weakened by a force that would outright kill almost anyone else.
* The [[BonusBoss Bonus Bosses]] of ''ManaKhemiaAlchemistsOfAlrevis'' are ''very'' powerful, to say the least. However, they all share a common monster trait that renders them vulnerable to a certain character's ''normal physical attack''. Yes, you heard that right.
** Which arguably lowers the difficulty of said Bosses. Said character is one of the highest physical attackers of the game (plus, he also has a skill that increases his attack power ''even more''), and abusing the weakness will quickly increase the LimitBreak meter, allowing faster access to the uber-powerful [[FinishingMove Finishing Bursts]]. This is a saving grace, however, since one BossBattle has you fighting ''[[FakeDifficulty three Bonus Bosses at once]]''.
* ''{{Touhou}}'s'' Rumia has one of the most deliberately humiliating weaknesses to a superpower in the series, and probably of any superpower, ever. She is vulnerable to using her own superpower. Her superpower is to spread darkness, which might sound useful for a predator, but her superpower effectively is to render herself blind. The [[AllThereInTheManual supplemental materials]] notes that many villagers have seen darks blobs of space slam into trees at high velocity. You probably shouldn't feel sorry for her, though, if she ''could'' see you, she'd insist on [[ImAHumanitarian coming over for dinner]].
* In {{Devil Survivor}}, the Nigh-Indestructible enemy is only harmed by Devil's Fuge [[spoiler: AKA Mistletoe, which the only thing made of said plant you can get your hands on is a ''cellphone strap'' that is only made in the image of mistletoe]]. Makes up for it by being {{That One Boss}} of the game, but still a rather undignified weakness - but [[JustifiedTrope justified]], due to [[NorseMythology the boss's background origin]] and the characters noteing that he is a demon.
* An odd case in TalesOfPhantasia, which isn't a conventional weakness, but more of a developers oversight. The BonusBoss of the BonusDungeon, Pluto, only has physical attacks, and one ridiculously long charging special attack, all of which have insane amounts of damage behind them,but must be used at close range. The first skill the main character ever learns is a long range, one SP cost move called Demon Fang', which ''instantly pushes pluto back and flinches him''. Hence, a BonusBoss battle where the heroes stay on oneside and nuke the poor guy and the lead constantly pelts him with Demon Fangs, while the boss sits on the other side of the screen defenseless.
* In ''{{Castlevania}}: Portrait of Ruin'', there's an optional battle with the spirit of [[spoiler:Richter Belmont]]. A hero from past games, he's one of the most powerful vampire hunters ever to walk the Earth. So what's the best weapon to use on him? Why, [[PieInTheFace cream pies]], of course!
**To elaborate a little: [[spoiler:Richter]] is weak against the Darkness element. One of the few sub-weapons you can get your hands on with this element is - for some reason - a cream pie. Which means the easiest way to beat him is to keep throwing pies in his face. Really.
* It seems that human(ish) enemies in the ''ResidentEvil'' series are more vulnerable to melee attacks than they are to heavy firepower and ordnance. Krauser from part 4 is weak against Leon's knife, and in part 5, the first two fights with Wesker can be considerably shortened by clobbering him with as many [[ActionCommands QTE]] combos as possible.
* In Resident Evil 4, the Plagas that hatch out of the various Ganados are either DemonicSpiders or GoddamnedBats, depending on your opinion. However, once "popped", they can be killed instantly with a single flash grenade... yes, that's right, the otherwise useless blue grenade you've probably been selling off for upgrades and beefier guns.
* The Ghost Pirate LeChuck in ''The Secret of MonkeyIsland'' had ''root beer' as his weakness. He got over it when he reincarnated as a Zombie though, it only seemed to affect ghosts.
** His weakness isn't root beer. It's antiroot beer, as in a drink made out of a ghost-killing plant.

* Toothgnip the goat in ''Goats'' gets his KavorkaMan powers from "The Panties of Potency". This had nothing to do with the artist having trouble drawing Toothgnip standing on all fours, honest!
* Parodied in [[http://www.giantitp.com/comics/oots0607.html this strip]] of ''TheOrderOfTheStick'', where, since Haley always has her sandwiches without pickles, Crystal thinks they're toxic to her. [[spoiler: They're not.]]
* Mr. Mighty of [[http://www.webcomicsnation.com/eddurd/everydayheroes/series.php?view=single&ID=72249 Everyday Heroes]] is bullet-proof and has "the strength of seventy men", but has trouble with [[http://www.webcomicsnation.com/eddurd/everydayheroes/series.php?view=single&ID=80611 paperwork]].
* In one ''Bob The Angry Flower'' strip, Bob thinks that a superhero has the Weaksauce Weakness of '''''bacon'''''. He turns out to be totally wrong, but we never find out what the weakness actually is.
** Another one has Bob running a hot peanuts stand, recognizing a customer and his friends as a band of supervillains, and [[StrangeMindsThinkAlike instantly and correctly deducing]] that they are actually buying ammunition for an attack on Anaphylactis Man's fortress. (He sells it to them anyway.)
* [[http://www.qwantz.com/index.php?comic=1582 This episode]] of ''DinosaurComics'' claims to have been inspired by this trope. More specifically, it's about the dangers of peanut allergies, orange juice, and the [[SuperDrowningSkills water that takes up 70% of the earth's surface]].

[[folder:WebOriginal]]
* In the ''WhateleyUniverse'', TheFairFolk (and mutants who are turning into Fae) are vulnerable to cold iron. Wrought iron benches, cast iron skillets, and so on. But Fey is also vulnerable to synthetic fabrics which give her a burning rash. She could be incapacitated by rayon lingerie!
** Or TheSeventies.
** Which is why editors and fact-checkers are used in published works. Cold Iron, Cast Iron, and Wrought Iron involve completely different processes, and often completely different chemical makeups. If that's the case, steel or any other Iron Alloy should be nearly as effective, blood could be an irritant, and hematite jewelry could be poisonous. but this would be taking away the "special-ness" of fancy kinds of iron.
*** This later receives a MagicAIsMagicA explanation, to keep it simple it involves magic, not normal chemistry.
*** And believe me, there was a ''ton'' of FanWank about this in the forums.
** Phase subverts this trope by getting a ''fake'' weakness put on his powers testing results. Dark chocolate, administered orally. So now she can have enemies try to stop her by bringing her delicious desserts.

* This trope appears as a pastiche in ''{{Bolt}}''. The titular dog believes he has superpowers because he never leaves the set of a TV show. When he is accidentally shipped across the country his powers "mysteriously" vanish, and he blames the Styrofoam packing peanuts he was shipped with.
* ''RobotChicken'' once spoofed SailorMoon's lengthy and "transparent" TransformationSequence with a male youma "[[GagPenis saluting]]" Sailor Moon.
** Similarly the transformations always end in the same pose. FanFic and H-Doujin writers take full advantage of this predictable moment.
* The titular character of ''InvaderZim'' is a member of a hyper-advanced, [[GeneticEngineeringIsTheNewNuke genetically engineered]] race of aliens for whom {{Humongous Mecha}}s are a mundane occurence and whose sole purpose seems to be conquering the entire universe. His main weakness? Water (possibly just polluted water). And ''meat''.
** Though, unlike the ''{{Signs}}'' aliens above, he managed to devise a solution with a few minutes of thought, after literally stumbling onto Earth. The Signs aliens had studied the Earth before attacking, and still managed to fail.
* [[CaptainPlanetAndThePlaneteers Captain Planet]], being a paragon of clean Earth, is naturally weak against your usual forms of pollution (smog, toxic waste, etc.)... but did you know that that also counts the "pollution" of ''hate''? Yes, if he is even ''around'' someone who has enough hatred, bigotry, and malice in their hearts, he will keel over just as badly as if he was sprayed down by a year's worth of toxic waste. In fact, Hitler nearly did him in through this, simply by [[DeathGlare glaring at him]]. It should be noted this isn't just anybody's hate, it's ''Hitler's'', considered by many to be the most evil human being to live. It's unlikely that some random meanie could accompish something similar.
** It makes sense (in an in-story sorta way which doesn't make it any less Weaksauce) that hate would be a sort of pollution to him: In the ShadowArchetype FiveBadBand the villains eventually make, guess what Heart's opposite is?
** Oddly enough, he was nearly done in by crude oil in the pilot episode, despite the fact that crude oil is a ''natural resource'' that is the result of geological pressures. So it's more like his resource is loosely defined as ''anything icky'' rather than pollution or hate.
*** In the French dub of the pilot, he's not sprayed with oil, but with a random "toxic chemical". Still, that doesn't explain what kind of chemical it is, nor why Greedly has a ''hose'' of it in his cockpit. But he shouldn't have a hose of oil either...
** Captain Planet's weakness is a clear sign of EpicFail, since he is supposed to fight pollution. He amounts to an anti-virus program that instantly cuts out on the first appearance of a virus on the computer it's meant to protect.
** [[TheRealCJ This Troper]] always secretly hoped that there was Captain Planet villain whose gimmick was picking up rubbish by the side of the road. Forcing Captain Planet to decide between cleaning up the planet or ''touching trash'' always appealed to me.
*** Or like a firefighting superhero whose costume consists entirely of oily rags and flash paper.
* Namor the Sub-Mariner of MarvelComics is similarly affected by pollution (though not by hate, which is good, since he seems to run on it), but that makes sense, as he's a water-breather.
* The only thing that prevents Brother Herman from [[TakeOverTheWorld taking over the world]] in ''YinYangYo'' is the fact the he's allergic to panda fur. As long as Master Yo, [[LastOfHisKind the last panda on the planet]], is around, [[FailureIsTheOnlyOption failure will be his only option]].
** His brother Carl, The Evil Cockroach Wizard has been shown to be a very powerful villain capable of [[TakeOverTheWorld global domination]] himself, he has one glaring weakness: self-esteem. He's been defeated by insults and peer pressure, and his own low opinion of himself keeps him from going full-tilt against the heroes and his brother.
* In ''BeastWars'', the {{Transformers}} get hit with a particularly nasty one... Energon, [[PhlebotinumMuncher which they need to survive]], can cause lock-ups, short-outs, and other problems if they're exposed to too high an amount of energon radiation.
** Given that the amount of raw Energon was described as potentially being enough to allow Megatron to conquer Cybertron, and when the Vok were going to destroy [[ItWasHisSled prehistoric Earth]] they were going to do it by overheating the Energon until it detonated, [[EarthShatteringKaboom taking out the entire planet]], that may be like complaining about humans having a weakness to water when talking about drowning at sea.
* Stitch of ''LiloAndStitch'' is unable to swim due to his extremely high molecular density, making him vulnerable to any body of water large and deep enough for him to be unable to claw his way out of before he drowns. Other than that he is one of the most powerful creatures in his continuity.
* Birdman from the old Hanna-Barbera cartoons had the powers of flight, energy beams that shot from his hands, enhanced strength, and a personal force field -- and drew his powers from the light of the sun. Fair enough, there are plenty of other solar-powered heroes out there ({{Superman}}, [[XMen Cyclops]] ([[DependingOnTheWriter sometimes]]), [[TeenTitans Starfire]]). Unlike those heroes, however, Birdman apparently had ''no'' energy reserve; he became weak as a baby after being removed from sunlight for ''less than a minute''. As it was implied that being out of the sun for an extended period of time ("extended" apparently being something like five minutes) was fatal to Birdman, it's a wonder he didn't spontaneously drop dead at night. [[HarveyBirdmanAttorneyAtLaw No wonder he became a lawyer.]]
** And once he becomes a lawyer, he develops an entirely new WeaksauceWeakness, as he's completely worthless if he loses the Birdman insignia that he keeps on his forehead.
** "Becomes?"
* In an episode of {{Ben 10}}, it turns out that the leader of the Galactic Enforcers (an alien superhero team, said leader an obvious parody of Superman) has a devastating weakness to chocolate, which [[LampshadeHanging Ben himself points out]] is a lame superweakness.
* The members of the SushiPack are rendered powerless by any kind of heat, but even worse, they feel compelled to announce this every time a villain pulls out a heat lamp.
* WordGirl isn't so much defeated by a cute little kitten, but rather easily distracted by one. She also compensates for her language abilities by showing a complete lack of competence in art, poetry, and dance.
**''Poetry?'' That ''consists'' of the application of words!
* Parodied in {{Futurama}}: "The human was impervious to our most powerful magnetic fields, yet in the end he succumbed to a harmless sharpened stick!"
* An episode of ''MartinMystery'' had an alien fungus monster that had taken over a small down and replaced the inhabitants with clones. Both it and the clones could be killed with salt. As luck would have it, the small town just happened to be in [[http://en.wikipedia.org/wiki/Great_Salt_Lake northern Utah.]]
* [[BigBad Mumm-Ra]] from {{Thundercats}}, with a weakness to ''his own reflection''.
** The writers eventually realized this made Mumm-Ra too lame, so they had him get over it. The Thundercats had a harder time dealing with him after that. Even more so when he got an InfinityPlusOneSword of his own.
* When Buttercup wanted to become a better superhero in the ''PowerpuffGirls'' episode "Super Zeroes", she became Mange, a knockoff of DarkerAndEdgier comic book {{Anti Hero}}es -- ''{{Spawn}}'' in particular. However, when the time came for her and her sisters (both of whom also assumed their own "better superhero" identies) to go out and fight a monster destroying Townsville, Mange was the only one who stayed behind, saying it's too bright and that she only travels at night. Mange then spent the rest of the day sitting on the couch with Professor Utonium until night fell, arriving too late at the scene as the monster had already left (her sisters were also late for reasons of their own). The three girls spent the night under a tree. When the monster came back to face the girls again, Mange sits out the fight, perferring to stay under the tree's shade. This attitude led the monster to eventually call her "Little Miss Darkness who’s afraid of a little sun".
* In [[{{Gargoyles}} Gargoyles,]] the titular creatures [[TakenForGranite turn into immobile statues]] during the day, which leaves them extremely vulnerable. They try to work around this in various ways (working a deal with humans in exchange for protection, magic spells, etc.)
** Oberon's Children, like other portrayals of TheFairFolk, are all vulnerable to iron. Iron can disrupt their magic, actually ''hurt'' them, and imprison them. In his [[spoiler: not really]] first appearance, Puck is forced to obey Demona after being bound with iron chains. The Weird Sisters are also coerced into doing a favor in exchange for being released from an iron chain. Later, the TricksterGod Coyote is trapped in the ''robot'' Coyote's latest body which was constructed with iron from a magical cauldron. Their ruler Oberon, while not immune to iron, is powerful enough to withstand being ''impaled by an iron harpoon'' though it does cause him to wither in appearance for a short time.
* In ''[[TMNT2003 Teenage Mutant Ninja Turtles: Fast Forward]]'' Sh'Okanabo's first attempt to infect Earth with his [[TheVirus progeny]] is thwarted by...sunlight. Although this is handwaved as a particular, unexpected feature of Earth's, and Sh'Okanabo himself is not normally affected, dealing with his weakness is the thrust of his character arc throughout the remainder of the season.

* At least one US Cold War era propaganda pamphlet suggests that citizens of communist countries can leave the water on (as the government pays for it) to help destroy the current regime. If that isn't a pathetic weakness, nothing is.
** As explained by Robert Newman in ''From Caliban to the Taliban'', they also recommended slashing bus seats as a way of bringing down a government. Yeah, you go do that, meanwhile we'll be over here with our international media connections and that nice Mr. Mandela.
** One Soviet defector said that the Americans asked him how to destroy the Soviet Union. His answer? Stop selling them grain. In order to grow enough grain for themselves, they'll have to pay the people for it - and then produce goods which the money can be spent upon, otherwise why would the people want it?
* Germany's defeat from Russia wasn't due to advanced strategies and nice weapons... It was due to... Cold. Sure, cold can be really dangerous, but the bad part is that Germans didn't really plan it well. What defeated them wasn't cold, but [[IdiotBall ignoring the flagrantly obvious]] [[NothingCanStopUsNow due to]] an [[SanityHasAdvantages excess]] of {{pride}}, which is even more of a weaksauce than cold.
** Worse than that: oughtn't Hitler et al to have heard of a certain [[NapoleonBonaparte petit caporal]] and his disastrous Russian campaign? General Winter gets things ''done''.
** The Russian Army's extremely competant operational-level campaigning might have a small something to do with the whole thing...
** Hitler, BTW, didn't blame the winter but his own HQ which didn't prepare for it. Couldn't blame himself, since the Fuhrer is always right.
** The whole "General Frost" stuff is a post-war fabrication. While winter of 41-42 ''was'' indeed one of the coldest in the century, Germans still had the upper hand, they've just somewhat stumbled. The winters of 43-44 and 44-45, when they were kicked just about everywhere, were, on the contrary, rather warm. But defeated Nazi generals needed to save their faces in their postwar memoirs, so they dug out that Napoleon reference and ran with it. If you look at their wartime diaries, you won't find much blaming of the cold -- mostly, just those idiots in HQ who couldn't straighten out their logistics: Germans ''did'' have the winter gear, they just couldn't ship it to frontlines fast enough.
* Gastropods, especially slugs and snails, are composed mostly of water. So what defeats them? The anti-water: Salt.
* Giraffes can easily suffer fatal neck and head injuries just from ''falling over''. Don't believe it? Just imagine the whiplash with a neck that long...
* Koalas live in such calm environments that even a not that much strong noise can scare them literally to death.
* Plenty of human allergies, including life-threatening ones, involve hypersensitivity to really common and/or lame stuff. One of this troper's co-workers is allergic to ''canola oil'', of all things.
**And this troper knows a woman who can't eat anything except what she prepares herself and extremely pure substances like blocks of tofu, salad, and certain types of bread, because she is so deathly allergic to milk products that even the use of an extract or slight cross-contamination is too much to risk. This means she's grown up on such a boring diet that she doesn't even bother trying to make her food interesting. Eats meat without spices and so on, and finds lots of delicious things disgusting because of excessive levels of various flavors. She also gets hives from touching it. Her secondary weakness is nuts.
** If Dr Karl [[strike: Krusx]] [[strike: Kruzel]] [[strike: Kruzlen]] Dr Karl can be believed, there are also people allergic to sex.
***A god that inflicts this on a person is not a kind god.
*** To be more clear, there are supposedly some women who are allergic to a certain protein that men, er, ''produce''. One would assume that basic birth control methods would be equally effective in preventing the reaction.
** Peanut allergies, which seem to be on the rise these days. It doesn't help matters that so many food products have peanuts in them (though they do at least have warnings, due to the existence of such allergies). It fits under this trope because, heck, who would want to admit that they could be killed by a freaking ''peanut?''
*** Research shows that the rate of serious peanut and tree nut allergies is not actually rising; it's just that, with modern medicine, many more people are surviving with them instead of dying as children.
** Soy allergies. Not a very common allergy, but a very common product. Just try to find prepared foods, particularly in restaurants, that do not contain either soy protein or soy oil. The majority of commercially-prepared deep-fried foods, especially potatoes, are cooked in soy oil.
* Humans drown rather easily if you immerse them in this stuff that covers 70% of their planet.
** Not to mention that water composes about 65% of their body, actually.
** Though most of them are very capable of manoeuvring in it, so it does usually take quite a bit of effort to keep them down for long enough.
** And what of people with [[http://en.wikipedia.org/wiki/Aquagenic_urticaria Aquagenic Urticaria]]?
