Malicious Slander in Anime and Manga.
- Boy's Abyss: While Esemori was in bed asleep, Chako stripped down to her underwear and took a scandalous selfie of him and her in bed. Months later, she goes to an editor and gives him the photo in order to run a story of adultery since he is married to Nagi Aoe.
- Chivalry of a Failed Knight: Ikki was subjected to this by Ethics Committee, dispensing all sorts of lies to demolish his steadily-improving reputation during the qualifiers of Seven Stars Sword Art Festival. It gets bad to the point where Stella thinks that her relationship Ikki is the reason why he's under fire and considers breaking up with him to get the heat off of him.
- DNA2: A classmate of Kotomi's attempts this by telling her teacher during class that Kotomi had spent the previous night in a Love Hotel with her boyfriend. The reader knows nothing happened and, since Kotomi stands up for herself and demands to know if her classmate has proof, the class realizes that it's not true.
- In the 3rd OVA to Fushigi Yuugi, Mayo tells everyone that Miaka was selfish and irresponsible, and that she was a slut who kept going back and forth between Tamahome and Hotohori. (Which earns her a What the Hell, Hero? from both Taka and Boushin.)
- I Had That Same Dream Again: After Kiryu's father is arrested for shoplifting, his fellow students get wind of it and a rumor starts circulating that Kiryu is also a thief. Nanoka is shocked to learn that Ogiwara, the only other boy she's seen talking to and who she seemed to like as much as Kiryu, was the one who started the rumor.
- Isabelle of Paris: Thiers claims that the Laustins housed Count Red, when this cannot be further from the truth - Count Red chose to go to the Laustins estate and hold every member of the family hostage during his duel with Victor, and right before revealing his secret identity - Andréa Laustin - to Léon and Marie. However, Marie is crushed by a chandelier as a result of Thiers' forces shooting at the mansion, which she is unable to avoid as Andréa had her tied to a chair. Through Broken Tears, Léon proclaims Andréa is no longer his son and accepts death with his wife, refusing to move from the burning building. As a result of Thiers claims', not many people attend Léon and Marie's funeral, sans Isabelle, Jean, Jeanne, a few other Laustin family staff, and some bystabders who only attended to mock them.
- Monster: After Tenma rejects her (again), Eva follows him through the hospital shouting that she will tell everyone all about how he murdered her father. It doesn't help that the police already suspect him.
- One Piece: Nico Robin's backstory. After becoming the only survivor of an incident where the World Government decimated her home island, said Government spread these about her to convince people to turn her in to them. Among these were that Robin was some kind of "Demon Child" and that she sank several battleships during the incident (while actually those ships were sunk by a giant who had defected from the Marines, not Robin). What's more, said giant left the marines due to their callous treatment of civilians, which is why he was attacking the battleships in the first place.
- Peach Girl: Sae routinely encourages the rumors that Momo is a homewrecking slut, and uses the Wounded Gazelle Gambit to convince everyone that Momo is bullying her on top of that. It all falls apart after Toji and Kairi, as well as several other people Momo has directly screwed over with her antics, expose her as the awful person that she is.
- The Rising of the Shield Hero: Naofumi is the victim of a double-dose of this. On top of the Shield Hero facing prejudice as it is because of the Church of the Three Heroes declaring him an actual devil figure in the religion (due to most of Melromarc being human supremacists and the Shield Hero having aided demi-humans in the past), his very first traveling companion, Malty, also falsely accuses him of trying to rape her after his very first day in Melromarc, sending his reputation down the tubes, as well as trying to frame him for trying to murder her sister Melty (something she herself tried to do). Needless to say, when the true Queen returns and puts the King and Malty on trial, it is a very satisfying moment that ends up vindicating Naofumi.
- Sailor Moon: One of the monsters in the second season had a power like this. Droid Giwaku (renamed Mistrust in the first dub) was capable of warping someone's perception to make them believe their friends and loved ones are badmouthing them. Ami found herself victim to this when Umino and several others, under Giwaku's influence, began accusing her of being a cheater. They even planted fake answer sheets in Ami's desk. Ami was later confronted by illusions of the other Sailor Senshi calling her a cheater as well. However, when Giwaku tried this on Usagi and attacked her with illusions calling her a stupid, flat-chested crybaby, Usagi shot back screaming she already knew all that anyway.
- Shina Dark: The demon king Exoda awakens after a lengthy slumber to find his secluded island full of young girls claiming to be "sacrifices" - because someone came up with the idea that the demon king demands a thousand women to be his concubines. Exoda is not happy to find the libelous text going into detail about what he supposedly does to the girls, roughly ten each night. He is outright disturbed to find a prepubescent child among the crowd. At one point he laments that people come up with new slander every time he goes into slumber, which suggests this is only the latest in a long line of indignities.
- Defied in Spy X Family. After Anya gets her first Stella Star for saving a boy from drowning, her classmates are unable to believe it, since they all think she's some violent delinquent due to punching Damian on her first day of school. As such, they start debating that she may have gotten it via underhanded methods e.g. she pushed the boy into the pool to make it look like she saved him. Damian, however, is quick to shut these rumours down, pointing out that there's no way the faculty would give a Stella Star to someone who hadn't earned it, they're tarnishing Eden Academy's good name by honestly suggesting such a thing, and that if they don't like how the school does things they can just transfer somewhere else. Notably, this is the moment that convinces Anya that Damian might be worth befriending after all.
- Voltes V: Heinel attempts to manipulate the Voltes team by slandering its creator, Kentaro, as a traitor that despises Earth, a slave driver and an abuser in different occasions. He successfully manages to break their spirit many times, but they always come back stronger.
- Yu-Gi-Oh! R entirely revolves around some protegee of Pegasus trying to avenge (and revive) his master after being told that Yugi murdered him. Ironically enough, in the manga, Pegasus WAS murdered...just not by Yugi. The murderer, funnily enough, doesn't even appear in the series.
