There are some people no one wants to be around, either due to [[SmugSnake smarminess]] or poor hygiene (or both!) they seem to ooze from every pore and make the air around them noxious, and anyone they touch will feel like immediately disinfecting the area. For the Poisonous Person, that is exactly the case. They are [[HarmfulToTouch lethal to touch]] because their body naturally produces [[UniversalPoison universally lethal toxins]], emits radiation or carries a host of dangerous diseases. Of course, ''they'' are [[TheImmune immune]] to these hazards, but not so everyone else.

There are a lot of ways this can happen: [[FreakLabAccident falling into a vat of chemicals or bio-hazards]], becoming {{Curse}}d as a WalkingWasteland or with an [[PowerIncontinence uncontrollable]] TouchOfDeath, or [[BlessedWithSuck an autonomous deadly defense mechanism power]] that can't distinguish friend from foe. For extra angst (or [[EvilTastesGood yummies]]) the Poisonous Person kills those they touch because they [[HorrorHunger must feed]] on their LifeEnergy.

This is one of those "powers" that [[WhyAmITicking are difficult to miss]] when they first manifest, usually resulting in a dead younger sister at the hands of the Poisonous Person. Is it any wonder that they come to embrace BadPowersBadPeople and become villains? Of course [[PersonalityPowers they probably weren't nice to begin with]]. This kind of villain isn't just difficult to fight, but also ''very'' versatile in applying their power. They'll use the sweat from their brow to salt a field, fill darts with their poisonous tears, turn a bloody wound [[DefensiveFeintTrap into their enemy's demise]] by [[CombatSadomasochist cutting themselves]] to poison their blade. Some of them may even have [[PoisonIsCorrosive their poison be corrosive,]] [[HollywoodAcid if not throwing actual acidic stuff.]] Sometimes they may use [[ILoveNuclearPower radioactive poisoning]]. If their power is disease based, they make an excellent {{Plaguemaster}}. Or they might end up as a hapless TyphoidMary.

If they aren't evil, they'll usually get far, ''far'' away from anyone who they might hurt, like a modern day Medusa or King Midas... sans gold. If they're ''really'' lucky they'll have enough control of their power/curse to turn it on and off, or at least be able to live in urban areas by wearing full body outfits or hazmat suits.

It's worth noting that there is no "typical" Poisonous Person in terms of appearance. Some are mundane looking, others are [[AstonishinglyAppropriateAppearance astonishingly obviously poisonous]] as Hazmat shows above, and a fair number are drop dead gorgeous. Why is it all the [[EvilIsSexy pretty]] [[ArtifactOfAttraction things]] [[ArtifactOfDeath will kill you?]]

Not a PoisonousFriend (though giving a character both tropes would be all sorts of appropriate). Differs from MasterPoisoner in that the master poisoner knows his way around toxins, although the two can overlap if the Poisonous Person is sufficiently smart and well in control of their own toxins. See also WalkingWasteland, EnemyToAllLivingThings, TechnicolorToxin, and TyphoidMary.


[[folder:{{Anime}} & {{Manga}}]]
* Pannacotta Fugo from ''Manga/JoJosBizarreAdventure''. His Purple Haze ability spreads a virus that turns anything it infects to a puddle of bubbling goo in 30 seconds. While his teammates make liberal use of their own powers, Fugo uses his once and only once in the series, and for good reason, as he could accidentally kill them if he wasn't careful.
* In ''Manga/{{Dokuhime}}'' (literally, Poison Princess): 'It starts with poisonous herbs under the cradle. Then under the sheets. And inside the clothes. Even mixed in the milk that they feed the newborn. This way the child gradually gets used to poisons and becomes the perfect assassination tool - the "Poison Princess" whose every kiss, tear and even touch bring death. Her only chance of survival is to fulfill her duty as an assassin and find a way to live on in the enemy land she is sent to... if her heart is strong enough.'
* The bodily fluids of Dokuga from ''Manga/{{Dorohedoro}}'' are toxic to others. As such he bathes and eats separately and [[TheStoic never laughs or shows excessive emotion to avoid accidentally getting spit on his friends.]]
* A unique variant in the "Stink Bomb" story of the movie ''Anime/{{Memories}}'': a hapless employee at a pharmaceutical company accidentally ingests some funny red-and-blue capsules (instead of the blue-and-red ones that would have cured his flu.) As a result, he constantly emits from his sweat glands a HIGHLY toxic gas that can kill any animal instantly and short out electronics. Worse, its range, toxicity and density increase as he gets more stressed out, which is kind of a problem when the Japanese Self Defense Force and the American military send whole fleets to catch him. He doesn't catch on that there's anything wrong with him until literally the final second of the story.
* Kagero the Kunoichi in ''Anime/NinjaScroll'', whose blood was suffused with poison, effectively turning her entire body into an assassination-weapon. Even a kiss from her could be lethal, and doing anything beyond that is enough to break down even the NighInvulnerable. Tessai, one of the villains, whose body is apparently made entirely from rock, knocks her out and starts frenching with her (obviously intending to rape her when he's got more time), and then gets into a fight with the hero Kibegami Jubei. A few minutes in, the rock-dude basically just starts falling apart, as Kagero's poison catches up with him...
* ''Manga/{{Basilisk}}'', based on the same ''Kouga Ninja Scrolls'' as ''Ninja Scroll'' above, also has a Kagerou with the same poisonous body. In this version, she is [[BrokenBird a tragic figure]] who is desperately in love with a man she can never have because [[DeathBySex consummating that love would kill him]] and he's the future clan chief, and she's forced to watch him fall in love and with [[StarCrossedLovers another woman from an enemy clan]]. And not to mention, poor Kagerou ends up subjected to a BreakTheCutie process that's bad [[CrapsackWorld even by this VERY dark series's standards]]. [[MurderTheHypotenuse She doesn't handle it well]]. [[MurderSuicide Not well]] [[LoveMakesYouCrazy at all.]]
* Albafica Pisces in ''Anime/SaintSeiyaTheLostCanvas''. And his mentor, Pisces Rugonis.
** Also, Specter Basilisk Sylphid.
* There's a girl in ''Anime/SamuraiDeeperKyo'' who releases toxic spores or something around her, dissolving anyone she gets close to. Naturally, this makes her a very sad and quiet girl, leading to a CrowningMomentOfHeartwarming when another character gives her a huge hug, despite being slowly eaten alive by the poison.
* Magellan, the chief warden of Impel Down from ''Manga/OnePiece'', ate the Doku Doku no Mi (Venom-Venom Fruit) which makes him literally a Poison Man. He can produce everything from a toxin that can melt steel and stone to simple tear gas. (The most infamous way was being able to create a three-headed hydra that was ''made'' of poison, literally. His ''most'' deadly way to harness this came later, when he created a different poison-monster called Venom Demon: Hell's Judgment, which looked like a gigantic, skeletal-looking demonic beast. It was not only poisonous, it [[HollywoodAcid was incredibly caustic]], and according to him, was powerful enough to "destroy Impel Down itself".) He eats poisoned foods in order to fuel his powers, and his powers give him a liking for the taste, though it gives him terrible diarrhea. Given the fact that he's a BigEater (being a big guy), he has to spend ten hours a day in the bathroom, which combined with the fact that he has to sleep, means he can only work about four hours a day. Still, that didn't seem to be much of a handicap. He's presented as a guardian who [[AntiVillain only wants to prevent all the worst criminals in the world from terrorizing the public]].
** Hyozou in Fishman Island is a blue ring octopus merman. When pressed in combat he coats his blades in his poison and, were it not due to Luffy's AcquiredPoisonImmunity from fighting Magellan, would have likely killed Luffy early in the arc.
** In Punk Hazard, Master Caesar Clown is the owner of the Gasu Gasu no Mi (Gas-Gas Fruit). This allows him to become, produce, and control gasses. Thus far, he's mainly used poisonous gas. Luffy directly compares him to Magellan, a comparison which he seems to take offense to. Of course, Clown demonstrates just why the comparison is a bad one when Luffy proves [[AcquiredPoisonImmunity immune to his poisonous gases]]. Remember, he can control ''all'' gases, which makes him able to suffocate opponents simply by remotely removing all of the oxygen around them.
* Coco from ''Anime/{{Toriko}}''.
* Hanzo the Salamander from ''Manga/{{Naruto}}''. He implanted the gland of a poisonous salamander in himself, making his touch and even his breath toxic to others while giving himself some resistance to poison. He wears a mask partially to protect others from his breath and partially to protect himself in case, by freak chance, he gets hit in the side where the gland is, because rupturing unleashes a cloud of poison so strong even he'd be paralyzed by it. He can also summon a much larger salamander with its own poison breath.
* Zen from ''Manga/NuraRiseOfTheYokaiClan'' is from a poisonous bird youkai species. The poison is concentrated in the feathers of his wings.
* Rossi in ''Manga/{{Superior}}'' survived an experiment intended to make her blood into a universal antidote. It sort of worked--one exposure to it can treat almost any poison. A second exposure, however, will seriously harm or kill the victim. (Having exposed Sheila to it once, she uses it as an insurance policy of sorts in the event that Sheila needs to be killed.)
* Subverted with Muk in ''Anime/{{Pokemon}}'', where despite being living poison, it pretty much smothers Ash every time they meet and is also seen smothering Professor Oak frequently, yet neither suffers after effects.
* Self-inflicted version in Manga/YuYuHakusho: [[spoiler: the [[NoNameGiven unnamed]] [[FanNickname Lady Doctor]] aka Yusuke's other ancestor. She was a "shaman cannibal" who willingly consumed the flesh of people who died of illness so her body would develop antibodies and eventual cures. This doubled as self-defense against human-devouring demons: if any demon had a piece of her, they'd die painfully and slowly since her flesh was ''ripe'' with disease.]]
* ''Manga/{{Bleach}}'': Askin's powers include being able to calculate the perfect lethal dosage of any substance and alter it at will, even making things that shouldn't be toxic, like a person's blood, lethal above a certain dosage. In other words ''he'' isn't a poisonous person, but ''can transform you into one''.
* ''Manga/FairyTail'' gives us Cobra, the Poison Dragon Slayer. As the name suggests, he uses and eats poison to increase and restore his strength. His poisonous attacks, in addition to normal brute force, work both corrosively and toxically, slowing down movement before eventual death. As testament to the effectiveness of it, he damn near killed [[TheHero Natsu]] with it when they fought each other.
* The big schtick of Servant Assassin [[spoiler: aka Hassan of Serenity]] in Anime/FatePrototype. Her entire body is so toxic that merely ''touching'' her is an almost instant death to humans.
* ''Manga/{{Inuyasha}}'' has Naraku, whose body constantly oozes poisonous miasma. It's implied that all demonic power is inherently poisonous, and Naraku especially so due to being created from numerous fused demons.
* The original ''Manga/DragonBall'' had Bacterian, a competitor in the first World Tournament arc that Krillin ended up fighting in the quarter finals, a fat slob who used his [[NauseaFuel horrible hygiene]] as an offensive weapon. He almost won, until Goku pointed out that Krillin doesnt technically have a nose due to his character design, letting him beat Bacterian based on a visual joke.

[[folder:Comic Books]]
* DependingOnTheWriter ComicBook/PoisonIvy can poison people by simply touching them.
* Franchise/TheDCU:
** Chemo is a giant abomination who is ''made'' of poisonous chemicals, literally. He's the result of a MadScientist dumping all of his failed experiments in a giant, humanoid plastic container, which eventually came to life and gained a sort of quasi-sentience. Chemo is similar to {{Bizarro}} in that he's not really intelligent enough to be a villain on his own, but is often used as a puppet by smarter bad guys.
** Mister Bones, whose skin exudes cyanide. Most of his flesh is also invisible, so he looks like a walking skeleton. Actually a lot less villainous than you'd expect.
* Preston Payne, AKA the third Clayface, from ''Franchise/{{Batman}}'' has the ability to cause people to melt with just a touch. Other Clayfaces have also had this ability. Unfortunately for Payne, in his case it was because his flesh had become liquefied and he was in constant pain, melting other people being one of the few things that could give him relief.
* Omega Red from Creator/MarvelComics emits "deathspores" that leech the health from anyone and everyone around him (they even affect Wolverine to SOME degree)
* An extremely dark issue of ''ComicBook/UltimateXMen'' was centered around a boy who woke up with a mutation that caused him to emit a chemical that incinerated anyone around him, causing him to [[NightmareFuel wonder where his parents, then his neighbors, then everyone had gone]] as he unwittingly and accidentally ''wiped out his entire home-town.'' Wolverine, as the only one who could survive his presence due to his HealingFactor, was sent by SHIELD to track him down and kill him. (both because of the danger he posed and because the exposure of a mutant that dangerous would basically ensure that mutants would be hunted to extinction) When the boy was made to understand, he quietly told Wolverine "... just do it".
** Rogue could count as well, since contact with her skin steals life force, memories, and skills (and powers, if any) from most people. The longer the touch, the worse the effect, but even a few seconds is enough to harm {{Muggles}}. For a brief time, it was upgraded to "touch and die."
* The ''ComicBook/XMen'''s recurring foe Mojo can wither plants and age humans with his touch. His presence on Earth also causes natural disasters.
* Subverted in ''ComicBook/{{Watchmen}}'', where [[spoiler: Ozymandias]] sets up Dr. Manhattan to acquire a reputation as a Poisonous (well, Radioactive) Person. He's not, but so many people he'd associated with are revealed to have come down with cancer that the big blue guy gets crucified by the press, and soon leaves Earth, in part to dodge these allegations.
* Hazmat from ''ComicBook/AvengersAcademy'' (not to be confused with the one from ''Marvel Nemesis'').
* In a ''ComicBook/WhatIf'' issue, [[ComicBook/CaptainMarVell Captain Marvel]] was cured of cancer. Unfortunately, everyone around him started getting sick with cancer, and it was contagious. He caused plagues on Earth, and among the Skrull and the Kree, before he realized what was going on.
* A heroic example is Leezle Pon of the ComicBook/GreenLanternCorps, who is a super-evolved and sentient smallpox virus. Due to the deadly disease he can cause, he can't attend many GLC meetings or gatherings, but he played a pivotal role in defeating Despotellis, a [[EvilCounterpart similar, evil virus.]]
* [=DiNA=]: Simmons, the ''Crimson Plague''. She bleeds, you die -- horribly and instantly.
* June Covington, aka "Toxie Doxie", from the Franchise/MarvelUniverse. She can exhale DeadlyGas and has a toxin in her blood which is fatal within seconds, all thanks to a bit of genetic self-experimentation.
* Played straight (though with some narm) in ''Comicbook/SpiderManReign'', a four-issue miniseries set 30 years in one possible future. Peter Parker recalls how he accidentally caused the death of his wife, Mary Jane Watson-Parker, by giving her cancer due to prolonged exposure to the radioactivity in his semen. (This may have been based on a story in the mainstream Marvel Universe during ''ComicBook/TheCloneSaga'' where she ''almost'' died that way, her pregnancy worsening the radioactivity passed to her. It was more-or-less a modern version of the classic "Master Planner" story.)
* The ''[[ComicBook/TalesOfTheUnexpected Unexpected]]'' story "The Bride Was All Aglow" has as its protagonist a man so heavily contaminated in a nuclear plant industrial accident that even the air he exhales needs to be bottled and buried. Unusually for this trope, he's cancer-riddled and in constant pain, and has no more than two years to live.
* Toxyn from ''ComicBook/StrikeforceMorituri'' was able to generate a variety of biochemicals after touching someone, including deadly poisons.
* A storyline in ''[[Comicbook/TheAvengers Avengers West Coast]]'' #98-100 (September-November, 1993) features an ArchivedArmy scenario. [[Characters/TheBorgias Lucrezia Borgia]] serves as an agent of the [[DemonLordsAndArchdevils Hell Lord]] Satannish. She is granted AbsurdlySharpClaws coated with poison.
* In ''ComicBook/SwampThing'', Nukeface was a homeless man who ingested radioactive waste, apparently regarding it as akin to alcohol. He was comparatively unaffected in that he was still able to move about and was largely intact, compared to a man whom he shared his 'drink' who ''turned into a mess of sludge within only a day''. Ironically, a man working for the company responsible for dumping the radioactive waste followed approximately the same route as Nukeface did. His pregnant wife, out alone in the woods, found Nukeface; she felt sorry for him and lay down beside him to keep him warm for the night. The moment when she tells her story and her husband and the others who have been searching for her all back away simultaneously is one of the series' big {{Tearjerker}} moments.
* In ''ComicBook/HackSlash'', Acid Alice is a slasher whose body secretes an extremely potent acid when she is sexually aroused. The acid can strip human flesh to the bone in a matter of seconds, or have a potent psychedelic effect.
* ''LegionOfSuperheroes'' has the recurring villain Mano, a member of the Fatal Five, who has an incredibly lethal Touch Of Death as a result of being born as a mutant on his homeworld. How deadly is his touch? He ''destroyed his homeworld with it!'' As in, literally put his hand on the ground until the whole planet died.

[[folder:Fan Works]]
* In ''[[Fanfic/RyuugisTheGamesWePlay The Games We Play]]'', later in the story Jaune has to fight [[spoiler: his father, who has been infected by Conquest, basically a Grimm virus who infects everything he touches. Conquest gets all the memories of the people he infects, as well as their body, which means their fighting style as well. Jaune's father uses bombs.]] Before fighting Conquest, Jaune's mother was holding him off. The readers lose sight of them for a few chapters but when we get back, Jaune's mother is nearly dead and missing limbs, not from Conquest's attacks, but from incinerating any part of her body touched by Conquest's attacks, keeping her from being infected.

* In ''Film/TheWolverine'', Viperís mutant power renders her immune to all viruses and toxins, but she's able to secrete them with her fingernails and tongue.

* The TropeCodifier: "Rappaccini's Daughter", an 1844 short story by Creator/NathanielHawthorne. The title girl has been given a poisonous touch and breath by her OverprotectiveDad in a misguided effort to protect her from the evils of the world:
-->'''[[KnightTemplarParent Rappaccini:]]''' What mean you, foolish girl? [[BlessedWithSuck Dost thou deem it misery to be endowed with marvellous gifts]], against which no power nor strength could avail an enemy? Misery, to be able to quell the mightiest with a breath? Misery, to be as terrible as thou art beautiful? Wouldst thou, then, have preferred the condition of a weak woman, exposed to all evil, and capable of none?
* In Théophile Gautier's 1856 ''Jettatura'', the protagonist is born with the power of "evil eye" that can kill with a glance, without him wishing it or being aware of it: he takes a long time to find out the cause of all the deaths around him. [[spoiler:When he realizes that he's slowly killing the woman he loves, he puts out his own eyes, too late to save her however.]]
* Pollution in ''Literature/GoodOmens'' seems to fit this. He's one of the Four Horsemen, taking over for Pestilence, who retired in disgust after the invention of penicillin left him feeling useless.
* Also in ''A Prayer For The Dying'', by Steward O'Nan, [[spoiler: the sheriff (as well as the pastor and undertaker) of the town discovers that he is the one carrying the deadly plague to everyone. Disturbing for him, but maybe even more so for the reader who slowly learns that he has an uncomfortable obsession with death, and is a necrophile and cannibal.]]
* Creator/TerryPratchett's Literature/{{Discworld}} has Foul Ole Ron.... a homeless beggar so nasty that his smell alone can incapacitate werewolves. His stink has, over time, [[UpToEleven developed into a semi-independent life form]], probably more intelligent and certainly far more cultured than Ron himself. The stink has been known to leave Ron entirely to spend an evening in its reserved box at the opera.
* Harkeness in ''[[Literature/TheGrimnoirChronicles Hard Magic]]'' is a Pale Horse, and can inflict people with disease. He has complete control over his power, but that doesn't stop Stuyvesant from being completely paranoid about him.
* ''Raptor'' by Gary Jennings set in the declining Roman empire has a venefica. Veneficas are defined as "girl slaves who are fed certain poisons in increasing doses throughout their upbringing. By the time they are grown to maidenhood their own bodies are accustomed to these substances and are unharmed by them. However, so virulent is the accumulated poison that a man who beds with a venefica--or anyone who partakes of any of her juices--dies on the instant."
* When under stress, the Chelons from the ''Franchise/StarTrekNovelVerse'' secrete a poison through their skin. Ambassador Jetanien of ''Literature/StarTrekVanguard'' explains this to his Klingon diplomatic counterpart in order to warn him off; another Chelon posthumously kills a Hirogen hunter with his poison in ''Literature/StarTrekDestiny''.
* In ''Literature/ThePosterChildren'', Bice started displaying this while ''still in the womb''. Her mother died as a result, and Bice, abandoned by her father, was raised by the Foundation. All her caretakers had to wear hazmat suits, and she didn't manage to rein in her abilities until she was nearly seven.
* In Creator/StephenKing's short story "The Man Who Would Not Shake Hands", Brower has been cursed with a TouchOfDeath by an Indian holy man, whose boy had died while messing around in Brower's improperly-secured motor car. After months of self-imposed isolation from other people, he joins a poker game for a brief respite from his loneliness, only to kill a participant who grabs his hand to congratulate him for winning the pot.
* In ''Literature/{{Everworld}},'' [[WitchSpecies witches]] are a variant on this trope: their blood is poisonous, at least to plants. Apparently this is why they're normally killed through burning, drowning, etc.--spilling too much of their blood can make the land infertile for a long time. [[spoiler:[[TheSmartGuy Jalil]] and [[HeroicWannabe David]] are willing to take advantage of this when the African gods threaten them]].
* [=SandWing=] dragons in ''Literature/WingsOfFire'' have this ability. They have tails similar to a scorpions that they use to poison their enemies.

[[folder:Live Action TV]]
* Polutia from ''Series/BlackScorpion''.
* ''Series/TheInvisibleMan'' series 3rd episode [="The Catevari"=] has an escaped government experiment whose skin and scratches are poisonous to the touch.
* ''Series/TheFortyFourHundred'' has an episode about a woman who grows toxic spores on her body that explode and kill anyone within a specific radius to her. She becomes convinced that it's God's will that she kill everyone (for some reason) and eventually the characters have to kill her. Why, when people were risking their lives taking drugs that would give them superpowers, the government didn't just publicize ''her'' story instead of restricting it, is never mentioned.
** For that matter, [[spoiler: Danny]] is a borderline example. His power was to essentially infect anyone around him with Promicin, which had a 50/50 chance of either giving them new abilities or killing them. [[spoiler: Eventually, Shawn has to kill him.]]
* Tev from ''Series/{{Tracker}}''. In his natural form, he could kill with a single touch, though it took longer with humans and required sex.
* Episode "El Mundo Gira" of ''Series/TheXFiles'' featured two illegal-immigrant brothers whose touch caused other peoples' bodies to be rapidly and fatally overgrown by whichever fungal spores they happened to have on their skin.
* Yamiror from ''Series/PowerRangersSamurai'' poisons anyone who inhales the gas he breathes out. He can concentrate it enough that it even gets through the Rangers' helmet filters.
* In ''Series/{{Supernatural}}'', the [[Characters/SupernaturalDjinn djinn]] are able to poison their victims with a touch. The poison can produce hallucinations, a stuporous state, or in a large enough dose, death.
* ''Series/TheNewAvengers'': Midas in "The Midas Touch". Midas is the perfect carrier for diseases, and {{Plaguemaster}} Professor Turner turns him into a living weapon whose slightest touch kills.
* ''Series/UchuuSentaiKyuranger'' has Stinger, HumanoidAlien from Scorpius System. He can poison people by stinging them with his scorpion tail. While his poison has not killed anyone [[spoiler: yet]], it incapacitates the person with pain and fever. Scorpio, Stinger's brother commonly uses a poison that makes anyone affected into a zombie, which then turns into [[PoisonousPerson Poisonous People]] themselves as they can spread the poison.


[[folder:Myth and Legend]]
* OlderThanFeudalism: The Vish Kanya. According to Kautilya's ''Literature/{{Arthashastra}}'' these mythical Indian women are similar to Kagero from the anime ''Anime/NinjaScroll'', with poisonous bodily fluids gained through AcquiredPoisonImmunity, who killed people through intercourse.
* Myth/ClassicalMythology:
** Medusa was so superhumanly hideous that looking at her [[TakenForGranite turned the onlooker to stone]], whether she wanted them to or not. Only her two immortal sisters were immune. The three lived on an island far out to sea and avoided people.
** King Midas, who foolishly wished that everything he touched would turn to gold. So any living thing he touched instantly died. Yay...?
* Myth/NorseMythology: Jörmungandr and Níðhöggr both are giant, poisonous serpentine dragons. The strength of their poison? Jörmungandr fights Thor during Ragnarök, and it kills the God of Thunder.

[[folder:Professional Wrestling]]
* The move The Great Kabuki introduced to professional wrestling, which English speaking fans know as the "green mist" is called the "poison fog" in Japan. Though rather than a paralyzing or tissue destroying toxin, it is instead based on the practice of storing a spicy substance you can handle in your mouth and spitting it where someone else can't; in their eyes. In this case, the English name is actually more appropriate but many Japanese wrestlers do stroke their throats before spitting, as if to extract the fog from some kind of venom gland.
* Gomi-man, who vandalizes Wrestling/KaijuBigBattel by spewing it and those involved with toxic sludge. His body is toxic too, as it is made of trash from [[{{Joisey}} Jersey city]].
* In Wrestling/RingOfHonor, Hang Men 3 ripped [[Wrestling/HunterJohnston Delirious's mask]], stapled it to his head and then hung him with a chain, leaving him to bleed or suffocate to death. In retaliation, Delirious got a new red mask and developed a new version of the mist which would be dubbed "the red poison", designed to restrict the air ways of those it effected, so Hang Men 3 would feel what Delirious felt.[[/folder]]

[[folder:Tabletop RPG]]
* There's a ''Literature/WildCards'' character who has this. He is a zombie oozing with toxic waste.
* In ''TabletopGame/MagicTheGathering'' many creatures with the Deathtouch ability are like this, as are several things with Wither. The first kills if any damage is dealt, the other makes damage essentially permanent instead of resetting at end of turn.
** Getting 10 Poison Counters will cause a player to [[InstantWinCondition automatically lose]] regardless of their life total. Many creatures in the ''Scars of Mirrodin'' set have the Infect ability, which is like Wither when battling other creatures, and inflicts damage in the form of Poison Counters to players.
** Phage, the Untouchable. One hit from her and a player loses the game outright. Not because of her attack power, that's only a four, and players typically start with twenty. No, she kills thanks to this trope. She also automatically destroys any creature she does combat to and prevents such a creature from regenerating. The downside is, if a player plays her card via any way other than from his hand, then ''he'' loses the game.
** Pharika, the snake-like goddess of affliction in the ''Theros'' block, is strongly associated with poisons. Conversely, her vast pharmaceutical knowledge also makes her TheMedic and the local patron of healers.
* Ermordenung, a type of PoisonousPerson inspired by the Hawthorne story above, are a covert, lethal presence in the ''TabletopGame/{{Ravenloft}}'' setting.
** Same with their mistress, Ivana Boritsi, Darklord of Borca, but she did it to herself ''on purpose''. The others she "recruits" aren't given any choice.
* The Brothers of Ypres, from ''TabletopGame/VampireTheRequiem''. The bloodline's originator, Pvt Owen Thomas Jones, was a soldier embraced in the trenches of World War One and took advantage of gas attacks to feed on the dying. The bloodline internalized the toxins allowing them to create poisons from their bodies at the cost of only feeding on the poisoned.
** The Anvari also count, since their bloodline Discipline allows them to poison others with various drugs and narcotics at will, culminating in the ability to instantly cause a fatal overdose -- like the Brothers of Ypres, they can only satisfactorily feed on drug-polluted blood.
* In ''TabletopGame/ChangelingTheLost'', the Blightbent are this. They are elementals of pollution, and can deliberately poison people with a touch. Likewise, the [[ExactlyWhatItSaysOnTheTin Venombites]].
* Similarly, the Zeka Prometheans from ''TabletopGame/PrometheanTheCreated'', who were created with radiation. Their [[WalkingWasteland Wasteland]] is even nastier than most, since it irradiates the area as well, and naturally, getting too close to them results in death by radiation poisoning.
* Yet another example from Creator/WhiteWolf are Wood Aspected Dragon-Blooded from ''TabletopGame/{{Exalted}}''. The anima power of the Wood Aspects allows them to deliver a lethal magical poison via simple skin contact. Many Wood elemental Charms in the Dragon-Blooded arsenal likewise manifest as poisoning effects.
* Dark Eldar characters in ''TabletopGame/RogueTrader'' have an alternative career rank (fleshcrafter disciple) with a talent that lets them become this; their melee attacks gain the "toxic" trait, poisoning enemies they wound, and they become completely immune to effect of poisons and diseases
** While fleshcrafters are essentially neophytes to Haemonculus covens (Haemonculi being torturer-scientists and surgeon-artists), the real stars of this trope among the Dark Eldar are the Lhamaeans. Essentially an order of courtesans, and exemplars of Dark Eldar society, they are known for being incredibly cruel, imaginative lovers, and supreme mistresses of poisons. A common saying about them is that they can blow a kiss, ''and it can carry enough toxicity on the air to kill a person in seconds.''
** In the same vein, while a wide variety of creative and disturbing poisons and venoms are perfectly acceptable for use, the human and daemonic forces that worship [[{{Plaguemaster}} Papa Nurgle]] fill in this trope for very different reasons.
* ''TabletopGame/{{Pathfinder}}'' has a race called the Vishkanya, which come from the setting's India-analogue. As the name suggests, they're based upon the mythological Vish Kanya mentioned above, only with mild reflavoring -- they come in both sexes, and they are a very subtle form of SnakePeople (snake-like eyes, serpentine forked tongues, and subtly scaled skin). One of their iconic racial class archetypes is the "Deadly Courtesan", a Rogue based on the FemmeFataleSpy archetype, which specializes in disguising itself as an entertainer or prostitute to spy, steal and slay with impunity.
** [[PlagueMaster Plague Bringer]] alchemists can turn themselves into this by downing their own artificially brewed plagues.

[[folder:Video Games]]
* Of all the various Poison-types in ''Franchise/{{Pokemon}},'' Grimer and Muk fit best, as they are composed entirely of toxic sludge that can apparently kill plants on contact ''and'' keep anything from growing in that spot ever again. It can also cause a fever if someone so much as accidentally touches one, though their stench is so strong your nose would have to be broken to even consider that.
** Koffing's essentially a giant floating bag of extremely poisonous (and [[StuffBlowingUp extremely flammable!]]) gases. Its evolved form, Weezing, is two of them fused together, as if one wasn't bad enough on its own, and some Pokedex entries state that some Weezing exist that are ''three'' Koffings fused together.
** As for Poison specialists, there are Gym Leader/[[TookALevelInBadass Elite Four]] [[VideoGame/PokemonRedAndBlue Koga]], his daughter Janine, who are both ninjas, which may or may not be related to the implied difficulty of training these things, [[VideoGame/PokemonBlack2AndWhite2 Roxie]] who's a punk-rock musician, and many Bikers and Grunts throughout the series itself.
** Any Pokémon with the Poison Point or Poison Touch Abilities can inflict the Poison status on opponents by mere contact, making this list of Pokémon much larger than the above, covering the likes of Qwilfish (based on a porcupine fish) and Toxicroak (based on a poison dart frog).
** Hell, just about ''every single Pokemon'' can qualify due to being able to learn Toxic via TM, which is the only move besides Poison Fang to inflict the badly poisoned status. Not to forget, the first-listed Pokémon in the National [=PokéDex=] is the Bulbasaur line, who are ''Grass/Poison-type toads''!
** It's worth noting that this trope is averted in the case of legendaries. As of Gen VII, Poison is the only type to not have a corresponding legendary (outside of Arceus holding the Toxic Plate, and Ultra Beasts Nihilego and Poipole-line).
* Moke from ''VideoGame/TheReconstruction'' is a comparatively mild example--the fluid that leaks from his skin doesn't do much more than smell horrible. However, it indicates a natural affinity for poison, as reflected in his [[{{Plaguemaster}} style of magic]], which [[BadPowersGoodPeople contrasts quite much with his personality]].
* The Darkspawn of ''Franchise/DragonAge''. Their very blood is poisonous and those who survive infection by its taint become thralls of the Darkspawn and the Old Gods that call to them. The Grey Wardens' Joining inoculates the survivors against the more immediate and nasty effects of the Taint; however, their version of the Taint still allows other Darkspawn to sense their presence, and in thirty or so years the Taint will overwhelm them anyway. The disease they spread affects wildlife and the environment as well leaving wastelands populated by blighted horrors in their wake. [[spoiler: In ''Awakening'', should you choose to spare a Darkspawn Messenger and give him a chance to prove his good intentions, he will end up accidentally infecting people with the blight while acting as a GoodSamaritan.]]
* [[UnfortunateName Medicine]] Melancholy from ''VideoGame/{{Touhou}}'': She has the ability to manipulate poison in any form, and it's implied that she herself is poisonous.
* Cynder from ''VideoGame/TheLegendOfSpyro'' trilogy has poison as one of her powers in the third game... and she's ''Spyro's girlfriend''.
* In ''VideoGame/DefenseOfTheAncients'', the hero [[NamesToRunAwayFromReallyFast Lesale Deathbringer, the Venomancer]]. According to his BackStory, he experimented with toxins on himself.
* Cloe Walsh in ''VideoGame/NoMoreHeroes2DesperateStruggle''.
* This is one of the perks in ''VideoGame/{{Crimsonland}}''. It ''also'' has a [[ILoveNuclearPower radioactive variety]].
* White Pikmin from ''VideoGame/{{Pikmin 2}}'' are able to absorb poison and can poison animals who eat them. Unfortunately for them, this poison is not transferable by touch, so the toxin can't poison those that squishes these little guys.
* In ''VideoGame/LeagueOfLegends'', Singed is a chemist of the MadScientist variety with a number of dangerous chemicals at his disposal, including a stream of poison that he can trail behind him. His body is so heavily scarred and hardened from his tests that he serves as a tank champion.
* ''VideoGame/DungeonFighterOnline'': [[CombatPragmatist Brawlers]] become this after they awaken as a Hellcat and obtain a passive skill which [[StandardStatusEffects poisons]] enemies who hit her, the chance being greater if the Hellcat is bleeding. This is a result of building up [[AcquiredPoisonImmunity immunity to poison]], yet letting it build up in her system at the same time.
** "This poison does not exist to strengthen you. It uses you to become stronger. It is at your expense that its embrace becomes more formidable." -[[http://dungeonfighter.nexon.net/Magazine/Content.aspx?boardNo=600&contentNo=009wG Luise, the first Hellcat]]
* ''VideoGame/DarkSouls'':
** Gravelord Nito, First of the Dead. During the war against the ancient dragons, Nito unleashed a wave of miasma and death powerful enough to poison the immortal dragons. During the boss fight against Nito, the attacks from his sword can inflict the deadly "Toxic" status effect (which is basically "Poison" on steroids) on the player.
** Eingyi is the creator of two very rare Pyromancies that can poison others. He was banished from his home for this, and it is implied he might be the reason Blighttown got its name and its swamp is poisoned. If indeed he was, it backfired: he got poisoned too, and only survived thanks to the sacrifice of Quelaag's Sister.
** Then there's the Bleed version: Priscilla the Crossbreed was banished to what amounts to a holding cell for her Lifehunt ability. She's huge, fluffy and quite probably a sweetie, but what it boils down to is having a skill that makes you bleed out of every pore as if you've been pumped with decolagulents. You can kind of see why locking her up came to mind...
* ''VideoGame/DarkSoulsII'':
** Mytha, the Baneful Queen, discovered that a type of poison mined from the Harvest Valley made her beautiful and healthy, so she bathed in the stuff near-constantly. By the time the player reaches her, she's become a snake-woman whose head has fallen off, which she carries around by the hair.
** Sinh, one of the few surviving Everlasting Dragons, produced immense amounts of poison within his body. This was all released at once when Sir Yorgh pierced him with a spear, resulting in the death and Hollowfication of the Sunken City of Shulva. Though it is claimed that this "purified" Sinh's body, he still breathes toxic flames during the battle with him.
* ''Franchise/TheElderScrolls''
** The Destruction school of magic most famously has the FireIceLightning trio as its main damaging types of [[ElementalPowers elemental magic]]. In some games, it also includes various Poison spells which typically deal little damage up front but continue to drain the health of the target for a duration afterward.
** Atronachs are a type of unaligned [[OurDemonsAreDifferent lesser Daedra]] which are essentially the {{Elemental Embodiment}}s of the elements they represent. The most common are the [[FireIceLightning Flame (also known as "Fire"), Frost, and Storm]] varieties. Flesh Atronachs are another variety. Depending on the game, they can emit a constant aura of poison-like damage, are immune to poison, and/or are actually ''healed'' by poison-based spells.
** Spider Daedra, as [[ExactlyWhatItSaysOnTheTin their name might imply]], are a SpiderPeople form of [[OurDemonsAreDifferent lesser Daedra]]. They are {{Magic Knight}}s equally formidable in melee combat as well as when casting spells. They are known to favor various poison spells, in addition to [[ShockAndAwe shock]] spells.
** In ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', Daedroths, a [[NeverSmileAtACrocodile crocodilian]] form of [[OurDemonsAreDifferent lesser Daedra]], like to initiate combat by casting a ranged, large AreaOfEffect "Poisonbloom" spell.
** The Ebony Mail in ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' is an armor piece that you get for completing [[ManipulativeBastard Boethiah's]] [[OurGodsAreDifferent Daedric]] quest that has this effect, generating an aura that damages nearby enemies.
* In ''VideoGame/AWitchsTale'', Gretel's doll ability is to cast a powerful Vile spell.
* In ''VideoGame/AncientDomainsOfMystery'', one possible effect of TheCorruption is making poison drip from your hands, contaminating any food or potions they touch.
* In ''Franchise/MortalKombat'', [[LizardFolk Reptile]] is infamous for his acidic prowess, to the point that in ''VideoGame/MortalKombatX'', he gains a WalkingWasteland-like effect for one of his Character Variations!
* Pictured above is Hazmat from ''VideoGame/MarvelNemesisRiseOfTheImperfects'', he can make people sick from touching them.
* ''Videogame/{{Warframe}}'' has Saryn, a Waframe focused on spreading toxins and disease. Her initial ability lets her infect enemies with giant pus-filled spores that explode with popped, turning them into a living bomb while her final power is to spread a deadly gas all around her that disintegrates enemies.
* ''VideoGame/StreetFighterV'' has newcomer F.A.N.G., a MadScientist that works for Shadaloo whose moveset is the first to incorporate poison. His V-Skill has him firing a slow-moving, unblockable poison projectile that will chip away at the opponent's health for a few moments or until the opponent lands a hit on F.A.N.G. His V-Trigger has him surrounding himself in a cloud of poisonous gas that will continuously damage opponents as long as they stand close to him.
* ''VideoGame/KirbyPlanetRobobot'' features the Poison ability, which allows Kirby create clouds of toxic gas and puddles of ooze, both of which will continually damage anything that remains in contact with them while they persist. The ability is meant to take more of a DeathOfAThousandCuts approach to boss battles, as hit for hit, its attacks are rather weak compared to other abilities, but the sheer number of hits you can pile on is what makes it effective.

[[folder:Visual Novels]]
* Cardia, the PlayerCharacter of ''VisualNovel/CodeRealize'', is highly corrosive to anything she touches that hasn't been specially treated with a serum developed from her own blood. When a dog bites her in the beginning of the game and succeeds in breaking the skin, her blood causes the animal's head to melt off.

[[folder:Web Original]]
* Viper, a member of the Serpent Syndicate in the ''Roleplay/GlobalGuardiansPBEMUniverse'', has a "poison touch". Her teammate King Cobra not only has a poisonous bite, but he can spit his venom as a ranged weapon.
** Sekhmet is an Egyptian supervillain whose powers allow him to infect others with fast-acting diseases. And fast-acting can be read as "initial infection to full blown presentation" in a matter of seconds) diseases.
* Puppet of the Literature/WhateleyUniverse. Her blood and lymph are so poisonous she isn't allowed out of her room and visitors have to wear biohazard gear. She looks like a normal pretty teen except that her green blood gives her skin a green tint.
* The ''Wiki/SCPFoundation'' has found [[http://scp-wiki.wikidot.com/scp-1951 one such individual, living in a building tainted by radiation]]. It's not clear if the building (SCP-1951) or the person (SCP-1951-a) is the source of the radiation, but 1951-a is unable to even interact with guards on-site without the radiation he emits killing people. As a result, he's been forced to stay in the building forever, deprived of any human interaction.
** There's also [[http://scp-wiki.wikidot.com/scp-811 SCP-811]], a swamp-dwelling woman whose containment procedures require anyone entering her enclosure to wear a full hazmat suit and for good reason: she is a walking biohazard. She secretes mucus from the palms of her hands and soles of her feet that [[PoisonIsCorrosive corrode organic tissue into black goo]] (which she then absorbs into her skin for nourishment), She [[VomitIndiscretionShot vomits]] black tar that contains various infectious bacteria, she gives off [[DeadlyGas large amounts of methane]], hell even her ''sweat'' is a "mild skin irritant".
* There are a few of these people in ''Literature/{{Worm}}'', mostly among the [[NamesToRunAwayFromReallyFast Slaughterhouse Nine]]: Nyx has the ability to create illusions out of poisonous mist, and Miasma can emit a gas that causes brain damage.
* In ''Literature/{{Twig}}'', the protagonist, Sylvester, is this as a result of the treatment which grants him his AcquiredPoisonImmunity making his blood toxic enough to be used as an improvised poison.
* ''WebAnimation/DSBTInsaniT'': Ashley can shoot acid, and Michael can shoot poisonous snakes.

[[folder:Western Animation]]
* ''WesternAnimation/ActionMan2000'': Professor Gangrene can poison people by touching them. Grinder discovers this the hard way in Gangrene's debut episode (fortunately, he gets better thanks to Action Man stealing the antidote), and in a later episode Gangrene taunts Action Man to hit him with his bare hand, but Action Man is smart enough not to do so.
* ''Toys/{{Bionicle}}'': Lerahk.
* ''WesternAnimation/SkysurferStrikeForce'' has Noxious, who can spray an array of poisonous gasses from his wrist mounted gas guns.
* ''WesternAnimation/BarbieThePearlPrincess'' has Spike the stonefish. Lumina helps him by using pearls to cover his spikes.
* ''WesternAnimation/BatmanBeyond'' has Blight, AKA Derek Powers, CEO of Wayne-Powers Enterprises. He's a WalkingWasteland who emits radiation wherever he goes, held in check only by a thin veneer of artificial skin. When he loses his temper, it only makes the radiation worse.
-->'''Blight:''' You want to talk about poison?! I'' AM ''POISON!
* ''WesternAnimation/CaptainPlanetAndThePlaneteers:'' Meet his EvilCounterpart Captain Pollution!
* ''WesternAnimation/TeenTitans'':
** The monster from the episode "Snowblind" generates such deadly amounts of radiation that none of the Titans but Starfire (who's species isn't affected much by radiation) can touch it.
** From the same episode, [[BadPowersGoodPeople Red Star]] has this a major problem: he gives off dangerous amounts of radiation thanks to powers [[PowerIncontinence that he can't control]]. For this reason he isolates himself from the rest of society, refusing to get too close to other people out of fear of hurting them.

[[folder:Real Life]]
* Back in 1994 very specific circumstances led to what appears to be a woman's body essentially becoming toxic, causing illness in several people in the emergency room she was at before she died. The real cause is unknown but this is discussed in [[http://discovermagazine.com/1995/apr/analysisofatoxic493 this]] article.
* Some anti-flea medicines can effectively make a dog who takes these regularly be a walking flea poison trap. The evidence of this is finding dead fleas on the dog--presumably, they tried to bite and then died upon contact.
* Number 2 on [[http://www.cracked.com/blog/5-supervillain-origin-stories-ripped-straight-from-the-news this list]] describes a professor who, after undergoing experimental radioactive treatments for a thyroid condition, wound up with dangerously radioactive bodily fluids. Oh, and he was wanted by the police for escaping arrest when accused of pedophilia. Which means, at some point, a police radio SOMEWHERE was heard saying "The subject is considered radioactive and dangerous."
** It's even better than that, at the time some newspaper headlines warned people that a "radioactive paedophile" was on the loose.
* According to the show the Romans used to create "catevaris" by feeding small amounts of poison to a child over time until they developed an immunity to poison and deadly body fluids. Probably fictional. (Though [[http://en.wikipedia.org/wiki/Mithridatism at least one individual from Roman times]] seems to have pulled it off.)
* [[http://en.wikipedia.org/wiki/Harold_McCluskey Harold McCluskey]] was a chemical technician at the Hanford Plutonium Finishing Plant in the US state of Washington, who on August 30, 1976, was exposed to [[http://en.wikipedia.org/wiki/Americium americium-241]] at "500 times the occupational standard" due to an exploding glove box. His body registered on Geiger counters for the rest of his life[[note]]Though it's noted that by 1977, his radiation count did fall by 80%[[/note]] (he died almost '''eleven years''' later) -- and presumably long after.
* Many amphibians such as Fire Salamanders and Poison Dart Frogs have toxic skin secretions, and are poisonous to the touch. The frogs, at least, acquire this by eating certain insects whose poison doesn't harm them.
* Asymptomatic disease carriers, such as the (in)famous [[http://en.wikipedia.org/wiki/Typhoid_Mary Typhoid Mary]], can at the very least be said to invoke this trope in the minds of others.
* Wiki/TheOtherWiki has lists for [[https://en.wikipedia.org/wiki/List_of_venomous_animals venomous]] and [[https://en.wikipedia.org/wiki/List_of_poisonous_animals poisonous]] organisms (no, they're not the same thing).
* Believe it or not, ''human saliva'' can actually be quite toxic. At least, it is if you're a bird: they have little to no resistance to strains of bacteria found in mammals' mouths.
** Make no mistake, if a human bites you, ''[[SincerityMode seek a doctor]]''. Human saliva is full of (often violent) bacteria due to our peculiar eating habits feeding them and thus very dangerous if it enters your system in any way but kissing.
