13	->''"A drop of venom fell on his naked thigh, and the feel of it was like a white-hot dagger driven into his flesh. Red jets of agony shot through Literature/{{Conan\|TheBarbarian}}'s brain, yet he held himself immovable; not by the twitching of a muscle or the flicker of an eyelash did he betray the pain of the hurt that left a scar he bore to the day of his death."''
14	-->-- ''Literature/TheScarletCitadel''
15
16	A fairly common trope, where any particularly potent poison is incredibly corrosive as well. This is often used to let a hero identify an attack as poisonous without actually getting poisoned. Alternatively, it can be used to show just how strong a poison is (somehow) by having it [[AteTheSpoon dissolve the spoon]] being used to mix it.
17
18	Frequently bundled into a single damage type in games featuring ElementalPowers to explain how can it deal damage to both living creatures and [[MechanicalLifeform constructs]] or TheUndead.
19
20	Note that this may be justified (or {{Hand Wave}}d) in non-contemporary or fantasy works, as the characters might not understand that there even is a difference between acid and poison, or might not have a word for acid, or something. (Incidentally, not all acids are corrosive and substances on the other end of the pH spectrum, bases, can be dangerously corrosive as well.)
21
22	Obviously, any liquid that is normally that corrosive will be toxic to ingest. This trope is for the case when a liquid billed as a straight toxin is inexplicably reactive.
23
24	Compare AteTheSpoon, GargleBlaster, HollywoodAcid.

32	[[folder:Anime & Manga]]
33	* ''Manga/ApothecariusArgentum'': Argent is a "Basilisk", a type of SuperSoldier who has been exposed to various toxins from birth to the point they're integrated into his body chemistry. In one chapter, in order to escape from a dungeon, he bites open the palm of his hand and uses his blood to weaken the stone walls to the point he can punch through them.
34	* According to ''Manga/{{Beastars}}'', Komodo dragon venom is corrosive, and this isn't even the half of the series' [[ArtisticLicenseBiology breaks from real-world biology]].
35	* ''Manga/{{Bleach}}''
36	** The Arrancar Loly Aivirrne's Resurreccion has centipede-like tentacles which have a poison that erodes whatever it touches.
37	** [[spoiler:Gin Ichimaru]]'s bankai has the ability to completely break down the opponent, as [[spoiler:Kamishini no Yari]] is made of potent poison, and it turns to dust for a millisecond during expansion, meaning [[spoiler:Ichimaru]] can leave a small piece of it inside the enemy and vaporize then at any second after piercing them.
38	* In ''Manga/FairyTail'', Cobra claims his Poison Dragon Slayer Magic will cause the flesh of his foes he strikes to start to die and melt into mush with each successive hit (and Natsu ''does'' mention that his skin feels number with each strike). His BreathWeapon, on the other hand, is described as unleashing a host of dangerous viruses that invade the body and cause his foes to fall sick and die.
39	* In ''Manga/InuYasha'', Sessoumaru's poison claw attacks can dissolve bones. In a story late in the series, Sango also uses a poison strong enough to melt bone, causing [[WreckedWeapon significant damage to her weapon]] in the process.
40	* In ''Anime/{{Kaiba}}'', a poison disguised as wine spills and eats through whatever it touches.
41	* ''Anime/LittleWitchAcademia2013'' has a small vial of poison ''melt'' a huge monster, and the resulting sludge bores a clear round hole through the floor it was standing on.
42	* In a flashback in ''Manga/MuhyoAndRoji'', Rio shows her apprentice Biko how to brew an elixir that restores tempering but can be poisonous. To demonstrate the latter property, Rio spills a drop of the elixir, which burns a hole in the stone pavement at her and Biko's feet.
43	* ''Manga/OnePiece'' has several examples of this, most notably [[spoiler:Magellan]], whose powers allow him to create any type of poison he pleases, especially the corrosive variety. His ultimate techniques are so corrosive they could actually ''melt'' the entire prison he guards if he isn't careful.
44	** First seen in Alabasta when Crocodile tries to kill Luffy with a poisonous hook and winds up melting a boulder with it.
45	** The Giant Pit on the Skypeia Arc bites trees and pyramids, melting them with its "acid".
46	* In ''Manga/PokemonAdventures'', the poison from Koga's Arbok can corrode walls early in the RBG arc.
47	* In ''Anime/RoninWarriors'', the Poison Warlord [[DubNameChange Sekhmet]]/Naaza can use the bright pink poison emitted by his Snake Fang Swords to melt his enemies and the surrounding environment, turning a whole concrete building into a half-corroded mess with one strike. Said venom is powerful enough to leave marks even in the Armors of the other Warriors.
48	* In ''Manga/{{Toriko}}'', [[PoisonousPerson Coco]] can produce this type of poison after evolving his Gourmet Cells and learning Food Honor.
49	[[/folder]]
50
51	[[folder:Card Games]]
52	* ''TabletopGame/ArkhamHorrorTheCardGame'': In ''The Labyrinths of Lunacy'' standalone scenario, the second obstacle for Group B is a room filled with highly corrosive poison capable of quickly dissolving human flesh, unless you have an antidote.
53	* ''TabletopGame/MagicTheGathering'': [[https://scryfall.com/card/shm/193/poison-the-well Poison the Well]] shows a [[{{Hobbits}} kithkin]] carrying water in wooden pails, but where it has spilled out it's eaten holes in the ground. Apparently it's acid poison that only dissolves dirt.
54	[[/folder]]
55
56	[[folder:Comic Books]]
57	* A [[Comicbook/MonicasGang Chuck Billy]] story had the hillbilly visiting a MonsterMash that offers him poisoned coffee. Once he drops the cup following the werewolf startling him, [[https://4.bp.blogspot.com/-q9sHwKIiGIA/UnG1RI4eJvI/AAAAAAAABpA/vQj2Ac28agE/s1600/CHB_172+(7).jpg the coffee opens holes in the table]].
58	* ''Literature/LoneWolf'': In ''The Skull of Agarash'', a giak throws a vial at Lone Wolf that he blocks with his axe, the weapon getting melted in the process. Despite this, Lone Wolf identifies it as poison and not acid. (It does seems to produces toxic fumes, though, forcing him to use his PsychicPowers to protect himself.)
59	* In ''ComicBook/TheScorpion'', Several of MasterPoisoner Mejai's poisons are shown to be acidic. Armando uses one to burn through the ropes holding him at one point.
60	[[/folder]]
61
62	[[folder:Fan Works]]
63	* ''Fanfic/FateHaremAntics'': Assassin/Hassan of Serenity is a PoisonousPerson. Her poisons dissolve almost anything she touches, including stone.
64	* ''Fanfic/{{Memoirs}}'': The spider venom dissolves Akagane's armor and bodysuit and severely burns his skin.
65	* ''VideoGame/PokemonWack'': The Poison-type move Corrosive Spray can damage Steel-type Pokemon (who are normally immune to said type).
66	* ''Fanfic/TheSteepPathAhead'': The Hydra's toxic is corrosive enough to turn trees into wilted matchsticks.
67	* Poison can melt stone in ''Fanfic/FarceOfTheThreeKingdoms'', much to the shock of the doctor who prepared it.
68	-->'''Ji Ping:''' I have a degree in chemistry. That makes no sense.\
69	'''Cao Cao:''' Sorry, this book runs on the laws of drama, not physics.
70	* ''Fanfic/VoyagesOfTheWildSeaHorse'': The SuperSpit of Lilith, who has the [[ScaledUp Monocled Cobra]] [[{{Animorphism}} Zoan Devil Fruit]], is a venom that is shown melting flesh like acid on simple contact, causing it to slough wetly away from the bone.
71	[[/folder]]
72
73	[[folder:Film -- Animation]]
74	* In ''WesternAnimation/AsterixAndCleopatra'', the Special Iced Arsenic Cake make by Artifis is so toxic that the batter AteTheSpoon -- ''before'' he adds the acid.
75	* ''WesternAnimation/FernGullyTheLastRainforest'': During his song, the sapient gas cloud Hexxus spits what he refers to as "poison sludge" onto a nearby pipe, causing it to hiss and release noxious fumes.
76	* In ''WesternAnimation/ThePagemaster'', Dr. Jekyll offers Richard a bright green beverage which, when knocked out of his hand, dissolves through the wooden floorboards in a matter of seconds. Moments later, the liquid is revealed to be [[spoiler:the potion that turns Dr. Jekyll into Mr. Hyde]].
77	[[/folder]]
78
79	[[folder:Film -- Live-Action]]
80	* In ''Film/NineToFive'', Violet imagines poisoning her boss's coffee with something that dissolves the spoon. Averted when his coffee really is (accidentally) poisoned later.
81	* ''Film/BackToTheFuturePartIII''. Marty gets poured a free shot of whiskey by a bartender that wants to make sure he knows what they serve in his bar. Strong stuff all right -- the bar top smokes from the overpour. Marty wisely leaves it alone. (While not billed as poison, one shot of the same whiskey puts Doc on the floor.)
82	* ''Film/{{Clash of the Titans\|1981}}'': The Stygian Witches say that Medusa's blood is a deadly poison, and after Perseus cuts off her head her blood spews out and melts Perseus' shield, which was a gift from the gods.
83	* ''Film/CurseOfTheGoldenFlower'': It's strongly suspected by various characters that the queen's chronic illness is due to the "medicine" that the king puts in her tea and forces her to drink. In the end, she tosses the tea aside and it burns into the cloth it lands on.
84	* ''Film/TheDarkKnight'': When the commissioner's poisoned highball glass gets knocked over it starts eating a hole through his desk. Although in this case, it's reasonable to assume that the commissioner's whiskey ''was'' actually spiked with acid, not poison.
85	* In ''Film/{{Enchanted}}'', a poison apple eats through a biker's helmet.
86	* ''Film/TheHungerGamesCatchingFire'': While not explicitly described, the poisonous fog causes intense, immediate pain on contact, pain that lingers until the fog is washed off in water. This makes it somewhat similar to a blistering agent, though a water-soluble one (which makes very little sense).
87	* ''Film/JurassicPark'': When the ''Dilophosaurus'' spits venom into Nedry's face, he's blinded and a sizzling sound is heard, suggesting [[EyeScream the poison is burning through his eyes]].
88	* ''Film/{{King Cobra\|1999}}'': Once fully grown, Seth's venom is so potent that it dissolves half a person's face after being bitten once.
89	* ''Film/LegendOfTheBlackScorpion'': [[spoiler:Wu Luan]]'s hand starts to rot after he grabs a poisoned blade.
90	* ''Film/{{Mindhunters}}'': The poison-laced cigarette eats through a metal floor and the victim's boot... with her foot still inside... before killing her. It's not until later that one character states it's "some kind of acid" rather than poison, and even then it's based on assumption.
91	* ''Film/MurderByDeath''. One of the glasses of wine served to the guests is poisoned. When the wine is poured onto a cloth napkin, it burns holes through it.
92	* ''Film/PrinceOfPersiaTheSandsOfTime'': The poisoned robe corrodes its wearer's flesh [[spoiler:as well as the hands of the poisoner]], but somehow not its own cloth or the cloth it's wrapped in when presented to the victim. Perhaps it reacts with sweat.
93	* In ''Film/TheRock'', we see what [=VX2=] does to bare skin. One thing that's not addressed is how atropine can counter a blister agent. [[note]] In RealLife, atropine is a counter for VX, but VX is not a blister agent but, as stated, a frakking neurotoxin.[[/note]]
94	* ''Film/{{Skyfall}}'': Raoul Silva's malfunctioning cyanide suicide capsule somehow dissolves his teeth and upper jaw but fails to kill him. The result is a sunken left cheek (which he hides by wearing a dental prosthesis), bloodshot eyes, damaged gums, and slurred speech. Hydrogen cyanide doesn't work this way; it causes death by cutting off cell respiration, but it's possible the writers were [[HollywoodAcid confused by its alternate name of "prussic acid".]]
95	* ''Film/TwiceToldTales'': In "Rappaccini's Daughter", one of the plants in Rappaccini's poison garden is so toxic that it burns a hole in his glove when he attempts to take a cutting from it.
96	* ''Film/WonderWoman2017'': Dr. Poison's new gas can break glass, somehow.
97	[[/folder]]
98
99	[[folder:Literature]]
100	* ''Franchise/ConanTheBarbarian'': In ''Literature/TheScarletCitadel'', Conan faces a giant snake with venom so acidic it burns without even breaking the skin, leaving a scar for life.
101	* ''Literature/CradleSeries'': Discussed. Lindon is given an [[MadeOfIron Iron body]] specifically designed to counter poisons, and asks if he's truly immune to poison now. Eithan shrugs and says that anything that attacks the body can be a "poison;" at higher levels, poison [[{{Mana}} madra]] corrodes physical objects almost as easily as flesh. What Lindon's new body actually gives him is an overpowered HealingFactor. Which is a good thing, because he soon gains a power that corrodes his body from the inside, and the damage is mitigated by his healing.
102	* ''Literature/{{Discworld}}'' plays with this a lot, but most noticeably in ''Literature/InterestingTimes'', where the poison not only smokes upon contact but causes the imbiber to explode.
103	* ''Literature/DuneEncyclopedia''. The plant known as inkvine contains a liquid that is a mixture of hydrochloric acid and poison. When used as a whip, inkvine injects the liquid into the victim's body, causing long term pain and skin discoloration.
104	* ''Literature/TheEyesOfTheDragon'' features Flagg preparing a poison which burns away and twists the bowl of the spoon with which he stirs it. The corrosive power killing before the poison ''is'' addressed however, as when mixed with water or wine or ingested by the human body the poison stops burning holes through stuff -- it just kills you in an extremely unpleasant manner a day or two later.
105	* ''Literature/GestaDanorum'': As Thorkill and his companions sail away from Utgard in flight, flying demons rain poisonous slaver down on them. The voyagers take shelter under animal hides, but one man accidentally thrusts out his hand, and it withers from touch of the poison; a second man peeks out from under his cover, and goes blind; a third man then [[TooDumbToLive sticks out his whole head]], which is taken clean off at the neck "as if it had been severed with a sword".
106	* ''Franchise/HarryPotter''. Venom from the Basilisk's fangs is a corrosive substance. {{Justified\|Trope}} since the delivery method is through a bite. Also by the fact that it's highly magical, as evidenced by [[spoiler: its ability to destroy a [[SoulJar horcrux]]]]
107	* In ''Literature/TheHitchhikersGuideToTheGalaxyTrilogy'' there is a bit where Zaphod is drinking what is implied to be a Pan-Glactic Gargle-Blaster. ''"Zaphod giggled into his drink, which frothed over and began to eat its way through the marble bartop."''
108	* The poison of Satha, the giant serpent from Creator/RobertEHoward's stories:
109	** In "The Valley of the Worm", Niord, in preparation for fighting the titular EldritchAbomination, slays a Satha to use enhance his arrows with [[PoisonedWeapons the poison]]. after a few hours of dipping, the bronze starts to show corrosion, and the shafts would have been eaten through outright had Niord not been careful to keep them out.
110	** In "Literature/TheScarletCitadel", a drop of poison drops on Conan's skin as he stands in front of it, not daring to move. The pain is described as fierce, and the scar remains for the rest of his life.
111	* ''Literature/HumanxCommonwealth'': Alaspinian minidrags spit an incredibly potent neurotoxin that has been shown to eat through metal. Minidrags have no teeth, so they rely on their toxin's corrosive properties to get it into the bloodstreams of their enemies.
112	* ''Literature/MagnusChaseAndTheGodsOfAsgard'' describes Loki as having a face marred by scars from the venom of a snake dripping onto his face from the periods when his wife Sigyn has to empty the bowl that normally catches the venom.
113	* ''Literature/RiverOfTeeth'': When Houndstooth suspects that Hero may try to poison him when they first meet, he pointedly knocks the glass of sweet tea off Hero's porch rail, only for the tea to hiss and immediately [[ThatPoorPlant eat through the rosebush]] it lands on.
114	* ''Literature/SorcererConjurerWizardWitch'': A drink that the heroes suspect has been poisoned is knocked out of the hand of the person who's about to drink it, and the liquid starts eating into the floor.
115	* ''Literature/{{Temeraire}}'': Certain species of dragon, such as the British Longwings, are capable of spitting highly corrosive acid. They are stated to be descended from naturally occurring poison-spitting dragons, which were selectively bred for stronger poison until this became so concentrated as to act like an acid. While some characters early in the story refer to Longwing spit as poison, neither the dragons nor their handlers make the mistake, making this an in-universe example of the trope.
116	* ''Literature/TheWanderingInn'': The protagonist's most terrifying weapon, besides her pan, is the acid, she extractes from Acid Flies, which corrodes easily flesh, when it comes in contact with it. Not that she does it by herself, she rather lets her undead barmaid do the work.
117	* ''Literature/{{Wraeththu}}'': The title creatures' semen is a caustic poison. This is also true in the TabletopGame based on the novels.
118	[[/folder]]
119
120	[[folder:Live-Action TV]]
121	* ''Series/TwentyFour'': The nerve gas in Season 5 can eat through door seals. Handwaved in that it's mixed with a corrosive element.
122	* In the pilot of ''Series/Forever2014'', a chemist has been growing Monkshood plants and using them to create a concentrated poison. When confronted in his lab by an armed homicide detective, he throws a beaker with purple powder onto her gun hand and flees. She's able to get off a couple of shots, but the poison is painfully and visibly eating into the back of her hand. The doctor she is with warns her the poison is working its way into her bloodstream, and proceeds to neutralize it by spraying alcohol onto the area and then ''setting it on fire'' for several seconds before dunking it in water to put it out. Possibly [[JustifiedTrope justified]] in two ways; first, aconite ''can'' be absorbed through the skin, even in non-concentrated form, enough to cause toxicity and even death, and second, we don't know what ''else'' might have been in that beaker. If the aconite was mixed with something corrosive, then aconite is known to pass through ''damaged'' skin quite quickly.
123	* In ''Series/{{Grimm}}'', the spider-like tarantella's venom dissolves (digests) its victim from the inside-out.
124	* ''Series/TheHitchhikersGuideToTheGalaxy1981'': The sequence demonstrating the effect of drinking a Pan-Galactic Gargle Blaster ends with a close-up of the stuff, having been spilled when the drinkers succumb to unconsciousness, eating a hole in the floor.
125	* In ''Series/MahouSentaiMagiranger'', the Hades God Toad used corrosive poisons as part of his power set.
126	* ''Series/TheMandalorian'': Krayt dragons can spit acidic venom, which will dissolve flesh on contact but can also be dried to be used as a regular poison.
127	* ''Series/MightyMorphinPowerRangers'':
128	** The original series does this a lot when a poison attack is used on the Megazord. It can also shock, as Scorpina's sting does.
129	** ''Series/PowerRangersMysticForce'' does this twice in two different episodes. Once, a poisoned apple, seconds after Chip suspects it's no good, instantly blackens and deflates like a balloon. Later, a goblet of poisoned tea eats through a book on the table after it's knocked from the intended victim's hand. All the usual FridgeLogic applies.
130	* ''Series/StarTrekTheOriginalSeries'': In "[[Recap/StarTrekS3E20TheWayToEden The Way to Eden]]", the plant life of the planet Eden is full of acidic poison.
131	* ''Series/Warehouse13'': In "[[Recap/Warehouse13S4E9TheOnesYouLove The Ones You Love]]", when Myka's sister Tracy is affected by a cord that makes you murder your siblings, she slips something in Myka's tea. When Myka spills the tea, it eats through the carpet.
132	[[/folder]]
133
134	[[folder:Mythology]]
135	* Myth/ClassicalMythology: Heracles (AKA Hercules) is slain when his wife is tricked into giving him a tunic to wear which has been soaked in the poisonous blood of the Lernean Hydra (a monster Heracles had previously slain as one of his famous Twelve Labors). The poison doesn't just somehow penetrate his skin and make him sick (with symptoms like nausea, dizziness, shortness of breath, or convulsions). The "poison" ''burns away his flesh''. On the one hand, the Lernean Hydra is a mythological creature, so who is to say it doesn't have blood like a "xenomorph" from the ''Alien'' movies. On the other hand, the Hydra is described as distinctly serpentine, and of course snake venom doesn't generally work like this. This makes this trope OlderThanFeudalism.
136	* Myth/NorseMythology: Another example of snake venom that is implied to be corrosive: After Loki is imprisoned by the other gods for his role in the death of Baldur, he is not only bound, but a serpent is placed above him that drips venom onto his face. His wife collects the venom in a bowl, but when she goes to empty the bowl, the venom drips onto Loki's face, which causes him to writhe in pain (as one would do if a caustic or corrosive substance were being dripped onto your face, but ''not'' as you would likely react to real life snake venom merely touching your skin).
137	* The Seps, [[http://bestiary.ca/beasts/beast270.htm a small serpent described in a 1st Century CE bestiary]], had venom which could dissolve flesh and bone.
138	[[/folder]]
139
140	[[folder:Tabletop Games]]
141	* ''TabletopGame/TwentyThreeHundredAD'': The animal life on Aurore makes use of acids in attacking its prey; some of the plants produce similar substances. Because of incompatible biology, these acids are also poisonous to humans.
142	* ''[[Literature/TheChroniclesOfAmber Amber]] Diceless Role-Playing'', ''Shadow Knight'' supplement:
143	** The standard form of the Envenom spell is a poisonous acid that prevents rapid healing and regeneration of wounds.
144	** Demons can have a bite which injects a highly caustic poison. It has the same effect on healing/regeneration as the Envenom spell.

184	* ''TabletopGame/HollowEarthExpedition'' supplement ''Secrets of the Surface World''. A wasp in the Amazon rain forest has a sting with venom so caustic it causes 2nd degree burns.
185	* ''TabletopGame/MiddleEarthRolePlaying'' supplement ''Rivendell: The House of Elrond''. One of the poisons listed in the 9.1 Herbal Chart table was Camadarch Acid. When mixed with alcohol, it inflicted Heat critical hits on the victim.
186	* ''TabletopGame/{{Pathfinder}}'':
187	** A tarn linnorm's venom deals acid damage. This is [[AWizardDidIt explicitly magical]]-- other linnorms have venom that deals other types of elemental damage, including fire, cold and electricity.
188	** This is averted with bilebearers, as their attacks are purely poisonous and deal no acid damage. The gutragers, described as a more developed form of the bilbearers, are however purely focused on producing and fighting with acid.
189	* ''TabletopGame/RuneQuest'':
190	** Supplement ''Dorastor: Land of Doom''. The claws of the powerful evil Chaos being Cacodemon inject a potent corrosive venom that can inflict up to 114 HitPoints of damage. The claws of his Fiend minions inject a similar poison that can do up to 20 HitPoints of damage.
191	** Supplement ''Trollpak'', "Book of Uz" part 2. Trolls control a type of giant whip-scorpion called a vinegaroon. It can spray a liquid poison that is highly acidic.
192	** ''Magazine/WhiteDwarf'' #45 article "Dealing With Demons". A sraim demon [[SuperSpit can spit]] acidic venom up to 10 meters away with a 50% chance of hitting.
193	* ''TabletopGame/{{Stormbringer}}''. In the ''TabletopGame/{{Stormbringer}} Companion'' supplement the Kyrenee monster's CombatTentacles are covered with an acid-based poison that causes serious damage to its victims and corrodes weapons that strike it.
194	* ''TabletopGame/{{Traveller}}'': In the ''Aurore Sourcebook'', the Bladehood plant stabs its victims with blades covered by a highly acidic poison.
195	* ''TabletopGame/TunnelsAndTrolls'': In one room of Solo Dungeon #4 ''Naked Doom'' there's a mist that's a dangerous acidic poison.
196	* ''TabletopGame/Warhammer40000'': The bioengineered implants and organs most [[SuperSoldier Space Marines]] have includes the Betcher's Gland, which connected to salivary glands and creates a highly acidic contact poison. Marines are able to [[SuperSpit spit the poison at opponents to damage and blind them]], though this is [[GameplayAndStorySegregation usually a moot point]] since they typically wear full helmets. It's been noted that [[HelmetsAreHardlyHeroic this isn't always the case]], and if they're captured it typically lets them [[BreakingTheBonds escape captivity]] if given time.

199	[[folder:Video Games]]
200	* ''VideoGame/ArmoryAndMachine'': Implied with the Giant Hogweed enemies. They have a "Venom" attack that deals heavy damage to your mechanical fighters, meaning that the attack is most likely corrosive for it to affect machines.
201	* ''VideoGame/{{Borderlands}}'': In-name-only. There are prefixes like "Pestilent", "Vitriolic" and so on, and the symbol for corrosive damage is a biohazard trefoil, but corrosive effects only work as HollywoodAcid and even deal ''less'' damage against fleshy enemies as opposed to armor (which it's very strong against), including robots that obviously cannot be poisoned.
202	** Played somewhat straight in the first game, in which enemies who are suffering from a corrosive DamageOverTime effect take increased damage from all sources. Later games moved this effect to other elements, most infamously slag in ''VideoGame/Borderlands2''.
203	* In ''VideoGame/CommandAndConquerGenerals'' (and the ''Zero Hour'' expansion pack), the GLA's "anthrax" (implied to be more chemical cocktail than just a viral agent) can and will eventually wear down armored tanks and fortified buildings.
204	* ''VideoGame/DarkestDungeon'': Blight is all over the place. Some disease-based attacks such as Plague Grenade cause it, but so do poison-related ones like Poison Dart and a select few like Digestion that imply acidity. [[PigMan The swine folk]] are said to resist it due to their filthy living conditions, implying a strong immune system[[note]]which generally isn't very effective at deterring corrosive agents like acids or reactive chemicals[[/note]], while [[DemBones Animated skeletons]] are especially weak to blight despite having no living tissue to poison, and similarly, Husks from the Color of Madness {{DLC}} are very weak to Blight because it allegedly corrodes their stony shells.
205	* ''VideoGame/DivinityOriginalSinII'' {{downplay\|edTrope}}s this: the Poison damage type isn't corrosive by default, but several Poison spells inflict the Acid StatusEffect, which destroys physical armour over time.
206	* ''VideoGame/TheElderScrollsIIIMorrowind'': Acid attacks and spells (like Acid Splash) count as a variety of Poison when it comes to calculating resistances.
207	* ''VideoGame/EnterTheGungeon'' has a generic green goo usually referred to as "poison" that can be dumped onto the floor in various ways -- green {{Blob Monster}}s and the Gorgun leave a trail of it behind them, mutant bullet kin puke it up, you can roll or break barrels of it, and various items let you emit some yourself. One of these, the Poison Vial, lampshades this in its description.
208	* ''VideoGame/FalloutNewVegas'': In the ''Dead Money'' DLC, the Sierra Madre Hotel and Casino is blanketed by a cloud of metal-corroding toxic smog. Possibly {{justified}}: [[spoiler: The Cloud's purpose was to force people to use the experimental auto-docs that were on-site to test their surgical programming]]; it makes sense that it would be more corrosive than poisonous.
209	* ''Franchise/FinalFantasy'' and similar {{RPG}}s can be assumed to use this trope with their poison-elemental attacks. Otherwise, they shouldn't deal any damage to mechanical or otherwise non-living targets. In some entries, such as the first, machines are indeed immune to poison.
210	* ''Videogame/GrimDawn'' draws a minor distinction, in that Acid damage is just the instantaneous version of Poison damage; the game prefers to keep its damage-over-time and instantaneous damage versions of the same element separate and differently-named.
211	* ''VideoGame/HollowKnight'': The poisonous orange gas does damage on contact, as does the yellow gas ''you'' can emit when you heal if you have the right Charm equipped. Could be considered a JustifiedTrope if you assume that, since it's a gas, it's being inhaled.
212	* ''VideoGame/LeagueOfLegends'': Cassiopeia has an ability called Miasma, which creates a circular pool of poison. It damages anything that walks over it, including robotic entities.
213	* ''VideoGame/LEGOAdaptationGame'': "Toxic Waste" in ''VideoGame/LegoBatman'' and ''LEGO Marvel'' insstakills most characters, with only characters already previously affected by toxins like Hulk or The Joker being able to NoSell and walk through it.
214	* ''VideoGame/MightAndMagic VI, VII,'' and ''VIII'' have the weapon modifiers "Of Poison," "Of Venom," and "Of Acid," which add various amounts of the same type of damage to a weapon: Poison damage in ''VI'' or Body damage in ''VII'' and ''VIII''.
215	* In ''VideoGame/MSSagaANewDawn'', the trope is subverted by being reversed: when you're dealing with HumongousMecha, the "poison" StatusEffect takes the form of acid, meaning that Corrosive Stuff Is Poison.
216	* ''VideoGame/PersonaQ'', in-battle banter uses this to justify why the [[StandardStatusEffects poison ailment]] still works on RobotGirl Aigis.
217	* ''VideoGame/{{Pokemon}}'' plays with this. While moves such as Acid are classified as {{Poison\|ous Person}}[[ElementalPowers -type attacks]], they are among the only Poison attacks that don't have a chance of poisoning the opponent. But [[DishingOutDirt Ground- and Rock-type Pokémon]] resist Poison-type attacks (Poison-type Pokémon are also weak to Ground-type attacks), and [[ExtraOreDinary Steel-types]] are completely immune to Poison.
218	** Acid and Acid Spray both lower the opponent's special defence drastically (Acid Spray is guaranteed to do so) which is supposed to represent the corrosive aspect. Gets kinda gross with Gastric Acid -- literally stomach acid that negates the opponent's ability. There are no actual acid Pokemon, as all Poison types are variations on piles of sludge/garbage or animals with poisonous features (like snakes).
219	** Gulpin and Swalot, due to being [[ExtremeOmnivore giant stomachs]], can be said to be acid Pokemon, as there is no other reason for them to be poisonous other than their acid-spitting abilities, which constitutes poison in the Pokeverse. However, they do learn sludge, filth, and gas based moves as well, but these are probably to round them out as Poison-types, rather than leaving them with three attacks.
220	** Apparently, Dragalge's poison is strong enough to eat away at tanker hulls. [[GameplayAndStorySegregation However, it can't have Corrosion as its Ability.]]
221	** Salandit and its evolution, Salazzle, downplay this with their ability, "Corrosion". It negates the immunity to the poison status effect inherent to Steel-type Pokemon, and lets it poison other Poison-types. However, it doesn't allow them to deal base Poison-type damage against Steel-types, they're still immune to it.
222	** The move Corrosive Gas destroys all held items on the field except for the user's.
223	* ''VideoGame/{{Runescape}}'' has a salesman who sells 'all purpose-poison'. In one quest, you learn that it's used for things like polishing family crests and cleaning fountains.
224	* ''VideoGame/{{Vindictus}}'' has an Acidic Poison Pouch item that contains an acidic poison.
225	* ''VideoGame/WorldOfWarcraft'' has poisons and acids in the Nature category of magic. And many times if it's poison it's also acidic and vice versa. Though when it comes to some things, how close the two are is weird (mechanical enemies especially, some can be poisoned by a Hunter's Serpent Sting but others are immune, while they can all be harmed by acids; some enemies that are caustic piles of goo can be poisoned but are immune to other types of Nature damage; if you get hit by an acid attack chances are you'll also be poisoned for a duration of time; there's also poison attacks that don't actually poison but only do instant damage, acid attacks that don't do damage but lower your armor and poison that doesn't damage but lowers your speed [in fact one boss battle in the Trial of the Crusader involves having to remove one Jormungar Worm's Paralyzing Poison with another Jormungar's Burning Bile, an acid countering a poison]).
226	[[/folder]]
227
228	[[folder:Webcomics]]
229	* In ''Webcomic/GirlGenius'', the poison from the [[SicklyGreenGlow Green Glowy]] Things. One stings Dimo on the hand, Oggie [[AmputationStopsSpread chops his arm off]], seconds later the severed limb melts into green glowy slime.
230	* In ''Webcomic/JungleJuice'', the poison of the Dragon Millipede is treated as this to the point where if not for the Insect Human on the receiving end having the strongest carapace known in existence, they would have likely melted instantly. Even then it burned through their clothes where it impacted.
231	* In ''Webcomic/YokokasQuest'', Mao's ribbon weapon [[MorphWeapon in the form of a dagger]] [[WreckedWeapon is dissolved]] by a [[MixAndMatchCritter snake-centipede's]] poison, and their poison blackens anything it makes contact with, including Mao's clothes, his skin, and the ground.
232	[[/folder]]
233
234	[[folder:Web Original]]
235	* ''Website/SCPFoundation'':
236	** [[http://scp-wiki.net/scp-875 SCP-875 ("War Criminals")]]: SCP-875-1 are small flying insects about six centimeters long. They have a sting which injects a venom that is highly acidic and does serious damage to tendons and nerves.
237	** [[http://scp-wiki.net/scp-955 SCP-955 ("Mr. Sillybug")]]: If a specimen is threatened or startled, it will spray a corrosive mucus up to several meters away. The mucus contains a neurotoxin that causes severe pain on contact with flesh.
238	[[/folder]]
239
240	[[folder:Western Animation]]
241	* ''WesternAnimation/ClassicDisneyShorts'': In ''[[https://www.youtube.com/watch?v=r45taz9Boi0 Mickey's Garden]]'', Mickey prepares an insecticide in his backyard and the broom he's using to stir it "burns" from being inside it.
242	* ''WesternAnimation/{{Futurama}}'': In one episode, [[LethalChef Bender]] drops some drinks he mixed and right after he leaves they eat through the floor.
243	* ''WesternAnimation/LooneyTunes'': A common visual identifier of a potent poison has a character stirring it, lifting the spoon and watching it dissolve. This most often happens with horrible poisons, but also mysterious brews of the JekyllAndHyde variety and {{Gargle Blaster}}s.
244	* ''WesternAnimation/AMissMallardMystery'': At the end of the opening titles someone poisons Miss Mallard's drink, her nephew knocks it over, and the drink dissolves the wooden table.
245	* ''WesternAnimation/TheRealGhostbusters'': Overdone to the point of parody where a poisoned cup of milk eats through several floors. Given that they're living through a mystery author's last novel, the surreality of it is intentional.
246	* ''WesternAnimation/TeenageMutantNinjaTurtles2012'': Spider Bytez spits globs of venom that quickly dissolve objects it hits (and greatly hurts one of his own legs thanks to Raphael).
247	* ''WesternAnimation/TomAndJerry'': When Tom brews up a poison, he'll typically stir it for a while and then lift out a swiftly-dissolving spoon.
248	[[/folder]]

250	[[folder:Real Life]]
251	* Animal venom:
252	** Averted with snakes and lizards: while their venoms contain a variety of powerful toxins that can damage cells (cytotoxins), nerves (neurotoxins), and blood vessels (hemotoxins), these are only effective against living tissue. Since the epidermis (skin) is dead tissue, the venom has to somehow get past the skin to do any damage at all. Snakes do this by injecting their venom via their fangs, while the venomous lizards (Gila monster, beaded lizard, and some of the monitor lizards) bite first and then inject venom into the open wound. Even the powerful venom of the infamous "spitting" cobras can't penetrate the skin; cobra venom is a powerful irritant when it gets in the eyes, but it rarely if ever does any permanent damage, and there are no known cases of cobra venom getting from the eyes into the rest of the body.
253	** Some species of spiders have similar venoms, such as the brown recluse spider, which acts to dissolve the flesh of the victim, which is '''extremely''' painful.
254	** Nearly any spit-poison is acidic, as its primary function is usually to blind, which a normal poison wouldn't do.
255	** Formic acid is the main ingredient in ant venom.
256	* Hydrofluoric acid is very corrosive and highly toxic. It can diffuse through skin and spread fluorine around, creating all kinds of havoc -- mainly by precipitation of calcium fluoride. It leeches the calcium from your bones. In other words, it melts your bones from the inside out. It'll also take calcium from your blood, which is ''even worse''. Losing calcium from your bones weakens them. Losing calcium from your blood slows or stops your heart. Direct skin contact with even a small amount of hydrofluoric acid is rarely survivable without prompt treatment. Treatment that you're unlikely to get, because the human body also needs calcium to ''transmit pain signals'', leaving many victims entirely unaware that they've even been exposed until it's too late to do much more than say "poor bastard" and start making funeral arrangements. Treatment for HF exposure is to soak the exposed skin in a calcium-rich solution immediately. That way, the HF goes for that calcium rather than the calcium in your bones and bloodstream. And you'll still want to go to the hospital.
257	* Some poisons, most notably arsenic sulfides, will tarnish metallic silver (due to the sulfur, not the arsenic). This led to some royal families using silver spoons to detect poison.
258	* Concentrated potassium cyanide solutions are poisonous and corrosive for steel, copper and some other metals. With help of air, even gold may be dissolved.
259	* Vesicants (blister agents) are poisons that are not normally corrosive to nonliving matter, but corrode and burn flesh, leaving nasty chemical burns and blisters. Typical examples are mustard gas and [[AlienKudzu giant hogweed]] sap. It should be noted that the sap of various hogweeds creates burns when it comes into contact with UV light - chemicals in the sap can make one's skin hypersensitive to sunlight - a condition known as phytophotodermatitis. To make things worse, the same condition can be caused by celery, various citrus fruits, rues, wild carrots and other similar plants.
260	* Chlorine gas is poisonous to inhale precisely ''because'' it's a strong oxidizer. Iron will burn in chlorine. Fluorine is an even ''more'' powerful oxidizer. Both are extremely dangerous in many forms because they are capable of oxidizing things which have already been oxidized - and some fluorine compounds can be used to set asbestos on fire. Metal-fluorine fires are impossible to extinguish until the metal or fluorine runs out. [[BreadEggsBreadedEggs Chlorine trifluoride]] is used to process uranium and to make computer chips. It is worse than the pure halogens. It ''sets sand on fire'' -- and often produces chlorine, fluorine, and hydrofluoric acid as byproducts of melting and burning its way through things. You handle it by keeping it inside specially-prepared metal containers. If the stuff gets loose, it will spontaneously react "with such things as cloth, wood, and test engineers".
261	* Bromine is a weaker oxidizer than fellow halogens chlorine and fluorine, but it's a liquid, which means it is normally much more concentrated and more easily absorbed by skin. It is toxic, corrosive and easily evaporated, which means your lungs are also in danger, just like with flourine and chlorine.
262	* Oxygen is a very potent oxidizer and extremely toxic to organisms whose metabolism doesn't depend on it. Because of its abundance in Earth's atmosphere, most things which live on the surface, and most materials present on the surface, are already oxidized or resistant to oxidation. Even still, highly concentrated oxygen - about five times that of the partial pressure of oxygen on earth - is dangerous to living creatures over long periods of time, causing fluid accumulation in the lungs, likely due to the presence of free radicals, which, when excessively concentrated, overwhelm the body's natural ability to repair damage. Pure oxygen at atmospheric pressure can led to extremely vigorous combustion, including of materials which are not particularly flammable under ordinary conditions.
263	* The synthetic [[DrugsAreBad narcotic]] [[http://www.snopes.com/medical/drugs/krokodil.asp "krokodil"]] (disturbing image warning). So called because the skin around the injection site often becomes dry and flaky, like the skin of a crocodile, because it is so [[HollywoodAcid acidic]]. [[note]]It's made by cooking up codeine with [[NoodleImplements gasoline, turpentine, and hydrochloric acid, just to name a few things]]. It's cooked up usually by Russian heroin addicts who can no longer afford/easily acquire heroin, hence the mishmash of rather unsavory ingredients. Conversely, since codeine-containing medications are much more tightly regulated in the US, and heroin is much more widely available/affordable, it's not likely for krokodil use to catch on in the US.[[/note]] This stuff can result in flesh rotting and corroding right off, right down to the bone. For more absolute horror, it is ''incredibly'' addictive, which means that using it once may prevent you from stopping even as your skin rots off. Most krokodil users don't live more than 3 years after they start using it, and those that do survive and manage to stop are often permanently disfigured. Note that the corrosivity of krokodil comes from the half-assed chemical technology used by the uneducated, unskilled addicts. The pure desomorphine alkaloid that can be extracted from raw krokodil has no such effects, it's essentially the same thing as heroin. One of the problems of krokodil use is that the high doesn't last very long, forcing users to keep cooking and injecting it again and again, exacerbating the damage.
264	* Long-term methamphetamine use can damage teeth, cause skin lesions, and so on. These effects are generally not the result of pure methamphetamine -- they are from the corrosive chemicals used to produce the methamphetamine that were not removed from the final product. Methamphetamine itself, however, is neurotoxic and can cause nervous system damage.
265	* There's a reason why the bleeding nose is a sign of a cocaine addict – prolonged cocaine use through snorting can cause damage to the inside of the nose, including the dissolution of the nasal septum. Part of this is because cocaine is a potent vasoconstrictor, and part of it is because powdered cocaine is in the form of a hydrochloride salt and its dissolution can cause the freed hydrochloric acid to get to work on the user's nasal tissue.
266	* Cashew nut shells are saturated with skin-irritating, phenolic oil. Which is only corrosive to skin, not metal, as some people claim for cheap shocks. And one of its numerous uses is in medicine. Thus says Paracelsus: Everything is poison, and nothing is, for it's the dose that makes a poison.
267	* Hydrogen sulphide is a highly toxic gas which can also corrode many metals, especially steel, by reacting with them to form metal sulphides. This causes many problems is places such as sewers, where losses due to corrosion are estimated at $14 billion per year in the USA. However, this can also serve as a method of diagnosing H[[subscript:2]]S poisoning, as coins in the pockets of the victim will discolour when exposed to high levels of H[[subscript:2]]S. One of the most insidious things about H[[subscript:2]]S is how it quickly numbs your ability to smell it, so you may think that you've escaped to an area with fresh air when in actuality you are still breathing it in. As such, workers in environments where exposure can easily occur from leaking equipment (such as in oil refineries) are required to wear personal H[[subscript:2]]S detectors on them at all times.
268	* The bloodroot plant is so named because of its bright orange-red sap, which contains a poison that kills animal cells, so like some other RealLife examples it outright rots living tissue. Some have made this plant's juices into [[SpiceRackPanacea a salve for treating such things as cancer or skin conditions]], which predictably eats away at the user's flesh. This can easily cause permanent and gruesome damage.
