Frequently, when a character enters an evil or cursed area, they'll find that it smells really, overpoweringly bad. It usually smells of rotten flesh (or just "death") and grows more powerful as the investigator gets closer to the threat. Another variant is an evil being carrying a bad stench with it when it appears. Frequently one of the Horror Tropes.
This trope stems from the fact that dead and unclean things smell bad, so if somewhere or something smells bad, it's probably dangerous. The belief that demons smell of sulfur is also a contributing factor.

- Watanuki from ×××HOLiC came across some situations like this, but he's the only one who can sense it. One example is at Himawari's friend's school where the game, Angel, is taking place.

Since Subaru's Return by Death ability is given to him by the Witch, he also has this scent, which makes the other characters having a hard time trusting him.
- Gyo lives off this trope, since the monsters in question are undead fish corpses. Even living fish doesnt exactly smell good. As it turns out, the corpses are just a delivery system, the true evil is a form of semi-sentient bacteria that propogates itself using the gasses released by decay. It's even worse for infected humans since they aren't technically DEAD.
- Lupin III (Red Jacket)': in the episode Killing is the Smell of Wine, professional and amoral Psycho for Hire Hangman has both the ghoulish looks and the smell of a corpse. As for the evil part, not only he's an assassin, but he's also shown to be prone to use gratuitous violence and wanton cruelty at the drop of a hat.

Captain Jack Sparrow: Not that bad, really.
- The Three Mothers Trilogy (which consists of Suspiria, Inferno and Mother of Tears) more specifically invoke this, by mentioning that the earth that witches' houses are built upon becomes so deadly and pestilent by the evil and death that emanates from there, that the entire neighborhood has a sweetish, nauseating smell.

- In the short story "Jerusalem's Lot" (set presumably before Salems Lot) by Stephen King, all the buildings in the eponymous village smell terrible inside. This is probably due to the giant worm living beneath the church.

- The Elder Scrolls
- This is said to be the case for Scamps, the weakest and smallest known form of lesser Daedra who have a rancid smell. Oblivion's "Whom Gods Annoy" quest centers around a poor Leyawiin resident cursed with a staff that summons Scamps to stink up her home and annoy the hell out of her. While Scamps are generally in the service of Mehrunes Dagon, the staff was created by Sheogorath, the Daedric Prince of Madness and a morbid practical joker.
- The Sload are a race of "slugmen" native to Thras, an archipelago to the southwest of Tamriel. While they themselves operate on a Blue and Orange Morality, the denizens of Tamriel instead see them as Always Chaotic Evil.

- Coldharbour is the Daedric plane of Molag Bal, Daedric Prince of Domination and Corruption. The ground is sludge, the sky is on fire, and the air is freezing.

If that weren't all horrifying enough, it is said that the smell alone is enough to break most mortals. It is said that no mortals willingly visit this place except in error.

In the 2002 cartoon, Stinkor was actually one of Skeletor's more effective minions, his constantly produced stench gas so powerful it could cripple even He-Man. At one point, it was used to cause a stampede, the herd animals desperately trying to escape his stench.
- The Plutarkians from Biker Mice from Mars were a race of fish-like aliens who stole resources from other planets and also tended to smell horrible.

Worse, some of them aren't even that toxic, but are simply so utterly, overwhelmingly stinky that chemists who allow it in their labs are rare. The fact some of them can be smelled half a mile away when you spill a single droplet doesn't help, either. Selenium compounds seem to be particularly common offenders.
- Reportedly, you could always tell when a slave ship came to port; they stunk to high heaven with the combination of human waste, blood and other substances resulting from their chained cargo and their crews were often the worst paid and behaved of any kind on the sea.
