He just wants a hug.
There are some people no one wants to be around, either due to 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. In the case of the Poisonous Person that is exactly the case. They are lethal to touch because their body naturally produces universally lethal toxins
, emits radiation or carries a host of dangerous diseases. Of course, they are immune
to these hazards, but not so everyone else.
There are a lot of ways this can happen: falling into a vat of chemicals or bio-hazards
, becoming Cursed
as a Walking Wasteland
or with an uncontrollable Touch of Death
, or an autonomous deadly defense mechanism power
that can't distinguish friend from foe. For extra angst (or yummies
) the Poisonous Person kills those they touch because they must feed
on their Life Energy
This is one of those "powers" that are difficult to miss
when they first manifest, usually resulting in a dead little sister at the hands of the Poisonous Person. Is it any wonder that they come to embrace Bad Powers, Bad People
and become villains? Of course 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 into their enemy's demise
by cutting themselves
to poison their blade. If their power is disease based, they make an excellent Plaguemaster
. Or they might end up as a hapless Typhoid Mary
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 astonishingly obvious as poisonous
as Hazmat shows above, and a fair number are drop dead gorgeous. Why is it all the pretty things will kill you?
Not a Poisonous Friend

Anime & Manga
- Pannacotta Fugo from JoJo's Bizarre Adventure. 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 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.'
- A unique variant in the "Stink Bomb" story of the movie 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 Ninja Scroll, whose blood was suffused with poison, effectively turning her entire body into an assassination-weapon. Even a touch from her could be lethal, and doing anything beyond that is enough to break down even the Nigh Invulnerable. 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...
- 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 a tragic figure who is desperately in love with a man she can never have because 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 another woman from an enemy clan. And not to mention, she's subjected to a Break the Cutie process that's bad even by this VERY dark series's standards. She doesn't handle it well. Not well at all.
- Albafica Pisces in Saint Seiya: The Lost Canvas. And his mentor, Pisces Rugonis.
- Also, Specter Basilisk Sylphid.
- There's a girl in Samurai Deeper Kyo 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 Crowning Moment of Heartwarming when another character gives her a huge hug, despite being slowly eaten alive by the poison.
- Magellan, the chief warden of Impel Down from One Piece, 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 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 Big Eater (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 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 Acquired Poison Immunity 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 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 Toriko.
- Hanzo the Salamander from 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 Nurarihyon No Mago is from a poisonous bird youkai species. The poison is concentrated in the feathers of his wings.
- Rossi in 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.)
- Averted with Muk in Pokémon, where despite being living poison, he pretty much smothers Ash every time they meet and Ash suffers no after effects.
- Self-inflicted version in YuYu Hakusho: the unnamed 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, which doubled 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.
- Poison Ivy, when she wants to be.
- Chemo in The DCU.
- Also in The DCU is 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 Batman has the ability to cause people to melt with just a touch. Other Clayfaces have also had this ability.
- Omega Red from Marvel Comics emits "deathspores" that leech the health from anyone and everyone around him (they even affect Wolverine to SOME degree)
- An extremely dark issue of Ultimate X-Men 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 wonder where his parents, then his neighbors, then everyone had gone as he unwittingly wiped out his entire home-town. Wolverine, as the only one who could survive his presence due to his Healing Factor, was sent by SHIELD to track him down and kill him. When the boy was made to understand, he didn't resist.
- 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 X-Men's recurring foe Mojo can wither plants and age humans with his touch. His presence on Earth also causes natural disasters.
- Subverted in Watchmen, where Ozymandius 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 Avengers Academy (not to be confused with the one from Marvel Nemesis).
- In a What If? issue which Captain Marvel was cured of cancer. Unfortunately, everyone around him starts getting sick with cancer and it's contagious. He caused plagues on Earth, the Skrull, and the Kree before he realized what was going on.
- DiNA: Simmons, the Crimson Plague. She bleeds, you die— horribly and instantly.
- June Covington, aka "Toxie Doxie", from the Marvel Universe. She can exhale Deadly Gas 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 Spider-Man: Reign, 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 the Clone Saga 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 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.
- In The Wolverine, Viper’s mutant power renders her immune to all viruses and toxins, but she's able to secrete them with her fingernails and tongue.
- "Rappacini's Daughter"
- 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. 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 Good Omens 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, 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.
- Terry Pratchett's Discworld has Foul Ole Ron.... a homeless beggar so nasty that his smell alone can incapacitate werewolves.
- Harkeness in 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 Star Trek Novel Verse secrete a poison through their skin. Ambassador Jetanien of Star Trek: Vanguard explains this to his Klingon diplomatic counterpart in order to warn him off; another Chelon posthumously kills a Hirogen hunter with his poison in Star Trek: Destiny.
Live Action TV
- Polutia from Black Scorpion.
- The Invisible Man series 3rd episode "The Catevari" has an escaped government experiment whose skin and scratches are poisonous to the touch.
- The 4400 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, 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. Eventually, Shawn has to kill him.
- Tev from 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 The X-Files 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 Power Rangers Samurai poisons anyone who inhales the gas he breathes out. He can concentrate it enough that it even gets through the Rangers' helmet filters.
- In Supernatural, the 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.
Myth and Legend
- Older Than Feudalism: The Vish Kanya. According to Kautilya's Arthashastra these mythical Indian women are similar to Kagero from the anime Ninja Scroll, with poisonous bodily fluids gained through Acquired Poison Immunity, who killed people through intercourse.
- Greek Mythology:
- Medusa was so superhumanly hideous that looking at her 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...?
- Norse Mythology: Jörmungandr and Níđhöggr both are giant, poisonous serpentine dragons. The strength of their poison? Jörmungandr fights Thor during Ragnarök, and it kills the God of Thunder.
- 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.
- In Ring of Honor, Hang Men 3 ripped 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.
- There's a Wild Cards character who has this. He is a zombie oozing with toxic waste.
- In Magic: The Gathering 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 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 power, that's only a four, barely bigger than an everyday elephant. 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 The Medic and the local patron of healers.
- Ermordenung, a type of Poisonous Person inspired by the Hawthorne story above, are a covert, lethal presence in the Ravenloft setting.
- The Brothers of Ypres, from Vampire: The Requiem. 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 Changeling: The Lost, the Blightbent are this. They are elementals of pollution, and can deliberately poison people with a touch. Likewise, the Venombites.
- Similarly, the Zeka Prometheans from Promethean: The Created, who were created with radiation. Their 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 White Wolf are Wood Aspected Dragon-Blooded from 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 Rogue Trader 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
- 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 Snake People (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 Mata Hari archetype, which specializes in disguising itself as an entertainer or prostitute to spy, steal and slay with impunity.
- Plague Bringer alchemists can turn themselves into this by downing their own artificially brewed plagues.
- Of all the various poison-type Pokémon, 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 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 Koffing's fused together.
- As for Poison specialists, there are Gym Leader/Elite Four Koga, his daughter Janine, who are both ninjas, which may or may not be related to the implied difficulty of training these things and Roxie who's a punk-rock musician.
- Any Pokémon with the Poison Point Ability 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.
- It's worth noting that this trope is averted in the case of legendaries. As of gen VI, Poison is the only type to not have a corresponding legendary (outside of Arceus holding the Toxic Plate).
- Moke from The Reconstruction 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 style of magic, which contrasts quite much with his personality.
- The Darkspawn of Dragon Age. 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. 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 Good Samaritan.
- Medicine Melancholy from Touhou: She has the ability to manipulate poison in any form, and it's implied that she herself is poisonous.
- Cynder from the Legend of Spyro trilogy has poison as one of her powers in the third game... and she's Spyro's girlfriend.
- In Defense of the Ancients: All-Stars, the hero Lesale Deathbringer, the Venomancer. According to his Back Story, he experimented with toxins on himself.
- Cloe Walsh in No More Heroes 2: Desperate Struggle.
- This is one of the perks in Crimsonland. It also has a radioactive variety.
- White Pikmin from Pikmin 2 are able to absorb poison and can poison animals who eat them.
- In League of Legends, Singed is a chemist of the Mad Scientist 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.
- Dungeon Fighter Online: Brawlers become this after they awaken as a Hellcat and obtain a passive skill which poisons enemies who hit her, the chance being greater if the Hellcat is bleeding. This is a result of building up 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." -Luise, the first Hellcat
- Gravelord Nito, First of the Dead from Dark Souls. 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.
- The Ebony Mail from The Elder Scrolls V: Skyrim is an armour piece that you get for completing Boethiah's Daedric quest that has this effect, generating an aura that damages enemies that get too close.
- In A Witchs Tale, Gretel's doll ability is to cast a powerful Vile spell.
- Viper, a member of the Serpent Syndicate in the Global Guardians PBEM Universe, 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 Whateley Universe. 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 SCP Foundation has found 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 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 corrode animal tissue into black goo (which she then absorbs into her skin for nourishment), She vomits black tar that contains various infectious bacteria, she gives off large amounts of methane, hell even her sweat is a "mild skin irritant".
- There are a few of these people in Worm, mostly among the Slaughterhouse Nine: Nyx has the ability to create illusions out of poisonous mist, and Miasma can emit a gas that causes brain damage.
- Action Man: Professor Gangrene from the 2000 series 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 Genre Savvy enough not to do so.
- BIONICLE: Lerahk.
- Skysurfer Strike Force has Noxious, who can spray an array of poisonous gasses from his wrist mounted gas guns.
- Barbie The Pearl Princess has Spike the stonefish. Lumina helps him by using pearls to cover his spikes.
- 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 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 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 at least one individual from Roman times seems to have pulled it off.)
- 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 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 lifenote (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 Typhoid Mary, can at the very least be said to invoke this trope in the minds of others.
- Venomous animals.
