* In ''{{Inuyasha}}'', Sessoumaru's poison claw attacks can dissolve bones.

* ''DungeonsAndDragons'' 1st Edition supplement ''Deities and Demigods Cyclopedia''. The troglodyte deity Laogzed has skin oozing with an acidic poison.

* 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]).

* In ''[[{{Asterix}} Asterix and Cleopatra]]'', the poisonous cake make by Edifice is so toxic that the batter AteTheSpoon - before he added the acid.

* StephenKing's ''TheEyesOfTheDragon'' featured Flagg preparing a poison which burned away and twisted the bowl of the spoon with which he stirred it.

A fairly common trope, especially in anime, 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 dissolve the spoon being used to mix it.

The villain lobs an attack at the hero. The hero dodges, only to see the rock the attack hit start to dissolve. * gasp* It's poison!

Funnily enough, this actually has some TruthInTelevision. Most poisons tend to be bases and strong bases are just as dangerous as strong acids. They work slightly differently to acids, but bases will still eat a hole through your hand. Then get into your bloodstream... [[AndThatsTerrible and that's not good]].

* In ''{{Inuyasha}}'' Sessoumaru's poison claw attacks can dissolve bones.

* In Bleach, Loly's Resurreccion has centipede-like tentacles which have a poison that erodes whatever it touches.

* In ''{{Enchanted}}'' a poison apple eats through a biker's helmet.
* In ''TheRock'' we see what VX2 does to bare skin. One thing that's not addressed is how atropine can counter a blister agent.
** TheyJustDidntCare. Atropine is a counter for VX, but VX is not a blister agent, but, as stated, a frakking neurotoxin.

* ''CurseOfTheGoldenFlower''. Never actually stated to be poison, but normally you don't try to make people drink acid.

** It could have reacted with sweat, like crystal meth does in real life.

* ''HarryPotter''. Poison from the Basilisk's fangs was a corrosive substance. [[JustifiedTrope Justified]] since the delivery method is through a bite.

* StephenKing's TheEyesOfTheDragon featured Flagg preparing a poison which burned away and twisted the bowl of the spoon with which he stirred it.

* Int the {{Temeraire}} novels, certain breeds of dragon are capable of spraying acid. While some characters early on refer to it as poison, neither the dragons nor their handlers make the mistake, making this an in-universe example of the trope.

* ''StarTrekTheOriginalSeries'' episode "The Way to Eden". The plant life of the planet Eden is full of acidic poison.
* The nerve gas in Season 5 of ''[[TwentyFour 24]]'', which could eat through door seals. Handwaved in that the nerve gas was mixed with a corrosive element.

** In some entries, e.g. the first, machines are indeed immune to poison.

[[AC:WebComics]]

** This troper just assumed that that was a Spark-enhanced version of something like the digestive-enzyme poisons that really exist.

* Overdone to the point of parody in an episode of TheRealGhostbusters where a poisoned cup of milk eats through several floors. Given they were living through a mystery author's last novel, the surreality of it was intentional.

** To elaborate a bit: hydrofluoric acid is not a strong acid-- and that is ironically what makes it so dangerous. Strong acids, such as hydrochloric acid, are called strong because they are completely dissociated to ions when in water. Hydrofluoric acid in contrast remains partly on its non-ionized molecular form - which, unlike the ions, is capable of diffusing through your skin and spread fluorine in your [[DrStrangelove bodily fluids]], creating all kinds of havoc (mainly by precipitation of calcium fluoride, and it gets the calcium from your bones. In other words, it melts your bones from the inside out.). This also makes it extremely difficult to wash spillage away from your skin, as you only wash away the fluoride ions, while the molecular acid remains.

** Highly corrosive chemical are, by definition, dangerous to consume.
* Somewhat TruthInTelevision. The venom of some poisonous species of snake contain enzymes that kick-start the digestive process in a sense... though nowhere near the "instant disintegration" seen in TV/Movies. Snake venom is, after all, essentially just modified spit. Likewise, certain species of venomous snakes produce poisons that basically break down the muscles around the heart killing their prey.

* In ''TheRock'' a deadly neurotoxin is acidic enough to start dissolving the hazmat suits the bomb experts are wearing.
** It's mentioned that it ''does'' contain an acid, however that might work.
** We also get to see what VX2 does to bare skin. One thing that's not addressed is how atropine can counter a blister agent.

* Not sure if this counts, but the blood of a [[Alien Xenomorph]] is incredibly corrosive. The viewers are shown how it eats through about three floors of the spaceship.

* ''{{Pokemon}}'' is a bit iffy. While acid attacks are classified as poison attacks, they are almost the only poison attacks that don't have a chance of poisoning the opponent. However, Acid still falls under this trope because of its secondary effect of lowering the target's defense, effectively corroding away their protections.

**** It's liquor, that's what you do. You just toss it back, not try and savor it. It's not wine.

** It could have reactied with sweat, like crystal meth does in real life.

Funnily enough, this actually has some TruthInTelevision. Most poisons tend to be bases and strong bases are just as corrosive as acids. They work slightly differently to acids, but bases will still eat a hole through your hand. Then get into your bloodstream... [[AndThatsTerrible and that's not good]].

* HumanxCommonwealth: Alaspinian minidrags have a neurotoxin that has been shown to eat through metal.
** Justified in that minidrags have no teeth, so rely on their toxin's corrosive properties to get it into the bloodstreams of their enemies.
