These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: You can expect to deal with the very worst that the supernatural world can throw at you. Yet as the following slashers and cultists establish, sometimes you don't need to be a vampire or a werewolf to be truly heinous:
Larry Meeks, alias Captain Hook, is a small, pudgy, uninspiring man who runs a bait shop, dresses like he's going on a fishing expedition and has a fanatical hatred of anybody he thinks is better looking, more successful, or stronger then he is. A murderer since the age of fifteen, when he first determined to "prove himself", Larry baits in his victims with kindness, playing the role of the favourite neighbour or kindly uncle. Once he's won their confidence, he then subdues them with a gaffhook, and hangs them up in his fishing shack with thousands of tiny fish hooks embedded in their skin. Slowly draining his victims of blood over the course of several days, Larry then guts and cleans them "just like a pretty trout." Active for years, a recent invitation from the Subtle Collectors' Association (a cabal of like-minded killers) has convinced Larry that it is time to up his game, and he plans to move onto still bigger and better targets in the hopes of impressing upon his compatriots the is the best. Totally consumed by his need to hurt people, Larry spends most of his off time talking to his customers about his murders, using fishing metaphors to obscure what he's really going on about.
Harvey Ecks, known variously as The Rest Stop Killer, The Torso Maker, and (his preferred sobriquet) The Driver, had a dream when he was still in the womb. In it, he learned that by understanding the Dream Pattern, he would be able to gain total control over all reality. In his quest to achieve this goal, Harvey discovered that by forcing people to watch their limbs being amputated, he could make them reveal pieces of the Pattern. Once a roving killer who left headless torsos at rest stops, Harvey decided that this was too inefficent. Staking out a patch of the interstate highway, Harvey brainwashed diner waitresses, gas station attendents, and state troopers into blindly serving him, then installed video surveillance cameras on billboards. When he sights a likely victim, he forces his servants (who know him only as The Driver) to help him capture that person, whom he then tortures to death in the hopes that they will reveal more of the Pattern.
Thomas Salvatore, the head chef and owner of the Epicurean Club, is leader of the Pate de Fois Gras cult. A would-be chef, and gourmand, Salvatore was never able to get his restaurants to work. At least not until he'd visited Papua New Guinea and gained a taste for "long pig". Returning home, Salvatore recruited a gang of equally amoral chefs, purchased Briarwood Farms, and used it to raise his food of choice—human children. Keeping the kids locked in filthy cages, Salvatore and his compatriots force the children to bulk up on food and stimulants, before cutting out their livers and serving them to their patrons, none of whom have a clue what they are eating. Determined that he will be known as one of the world's greatest chefs, Salvatore plans to ride his new-found success all the way to the top—no matter how many children he has to butcher in the process.
The Lucifuge are probably the nicest group, despite their demonicancestry, but no one really trusts them because of it.
A meta-example would be the changelings. In addition to their own crappy backstory, they're the most harmless monster in game... and the one that every single Hunter group distrusts. They're seen as liars, Body Snatchers, and evil doppelgangers of the people they've kidnapped, the exact opposite of what they really are. Some hunters actually think they're the vanguard of an alien invasion. They're absolutely justified in their fears— the problem is, they've got the wrong target! The lying, body-snatching, evil invading aliens are oh so very real, but they're the True Fae, not the changelings. The Hunters mistake changelings for some kind of mini-Gentry, instead of the (mostly) harmless refugees they really are. This mirrors the confusion changelings themselves have in identifying True Fae loyalists. Once you see a changeling ravage your wife's mind in her dreams and invite the Wild Hunt to your street, you are to be expected to treat them, as a group, no better than bloodsuckers, shapeshifting human-eaters, and witches.
