Examples of in  fan works include:


 * The Friends fic Somebody Save Me (found here) has portrayed Richard—a perfectly nice, well-loved guy whose relationship with Monica only broke up because of May–December Romance problems—as a drunken, selfish, physically and emotionally abusive rapist who does not care for Monica at all, so that Chandler can be there to protect and rescue Monica from her evil abuser. Why an OC abusive boyfriend could not have been made up, seeing as Monica dates dozens of men throughout the run of Friends, is a mystery. It's not the only one of its kind either.
 * One particularly bad and extremely unsettling NSFW Degrassi fic called The Junkie Journals turns Riley Stavros into a rapist, Mind Rapist, gay-basher, drug addict, Jerk Jock, Villain Sue, and Karma Houdini. He's such a Complete Monster that people walk away from the story feeling like they've come across the seedy underbelly of the world. All of this without warning or explanation. The main character of the story is also rescued by Peter but it's a mystery why the so-called "author" couldn't just make up an OC who's a Complete Monster instead of having to defile Riley's character.
 * Allecto's controversial critiques of Firefly are something of an extreme example of this; the actions of several of the characters (and especially the white male ones) are often twisted in order to fit an extreme feminist reading, thus unfairly painting them as evil.
