* ''VisualNovel/Adastra2018'' has a cast of characters who are made up of anthro animals (with the exception of the main character Marco), and the story they are in has swearing, NSFW images, political conflict and corruption (ranging from sabotage to [[spoiler: regicide committed by one of the characters before the beginning of the plot]]), a heavy sense of friction in the story's tone and a handful of scenes that involve brutal violence (with detailed descriptions).
** ''Khemia'', the sequel story, also qualifies for this trope. In the first released build alone, all the examples above (from the profanity to the brutal violence) surface at some point.

* ''VisualNovel/{{Echo}}'' (which was made from the same studio behind ''Adastra'') is about a group of six anthro animal friends meeting up in their titular hometown for a reunion, where things soon take a turn for the dangerous when buried memories and paranormal events start to gruesomely unravel around them. Topics such as bullying, abuse and mental illness are often brought up in explicit detail and many moments in the story [[spoiler: (ranging from evil entities to brutal character deaths)]] would easily fit in an R-rated horror film.

* ''VisualNovel/GloryHounds'', also made by the same people as ''Echo'' and ''Adastra'', is a superhero story with mature themes whose main character is a dalmatian. Still, compared to its brethren it is more campy.

* [[https://www.youtube.com/watch?v=gQOVMzzDd5s The Vanishing of S.S. Willie]] is an AnalogHorror based off of ''WesternAnimation/SteamboatWillie''. It takes place in a WorldOfFunnyAnimals and is presented as a lost 1928 documentary about the disappearance of the titular ship. When the ship is found by the expedition crew, what happened to the crew is revealed as [[spoiler: the BlackComedyAnimalCruelty in the original short is PlayedForHorror as all but the Cabin Boy and Chambermaid are found dead with their corpses mutilated in various ways.]]

* ''Fanfic/DeathAndTaxes'' takes characters from ''WesternAnimation/HappyTreeFriends'' and drops all cute and cuddly pretenses that show has, recontextualizing them as ordinary citizens in a WorldOfFunnyAnimals. What's left is an EldritchHorror story about a cursed town, and the various awful events that happen to the pastel characters living inside.

* ''Fanfic/ApprenticeAndPregnant'', another ''Literature/WarriorCats'' fic, is based on a kid's series but isn't aimed at the target audience. It deals with darker topics like rape, TeenPregnancy, and DomesticAbuse.

** ''FanFic/TheWritingOnTheWall'' [[ExploitedTrope exploits this trope]] for its impact. The story starts out like a lighthearted bit of pulp fiction about AdventurerArchaeologist JustForFun/DaringDo exploring an ancient tomb with her crew, with the only dissonant note being that the ruin is 71,000 years old - far older than any civilization known to have been able to use masonry, with a series of warnings written in increasingly ancient, indecipherable languages. This leads to a case of WrongGenreSavvy not only of the characters in the story, but also of the reader, as people in the camp begin to get sick, with the true nature of the "tomb" - and the true genre of the story - only revealed after the ominous writing on the wall is deciphered at the end of the story.

* ''FanFic/MemoirsOfAMaster'' is a ''WesternAnimation/KungFuPanda'' story where Po and the Furious Five read the personal memoirs of Master Shifu; a tale of trials and profound loss experienced by a martial arts master who found redemption where he least expected it through Po.

* ''FanFic/WhatLiesBeyondTheWalls'' is a ''Literature/{{Redwall}}'' fanfic that not only contains explicit sex scenes, but also focuses on [[WarIsHell the brutality of war]] and how it can easily corrupt others. It also shows how [[GreyAndGrayMorality gray]] the world really is, and doesn't waste time revealing that everyone on both sides isn't 100% good or evil.

* ''VideoGame/{{Armello}}'' is an [[AdventureBoardGames Adventure Board Game]] starring anthropomorphic animals and focusing on a ''[[Literature/ASongOfIceAndFire Song of Ice and Fire]]''-esque fantasy power struggle, with all the cruelty and bloodshed that entails.

* ''VisualNovel/SuperNova'' is a superhero story with anthropomorphic animal characters. It portrays itself relatively seriously, dealing with ThouShaltNotKill and the legacy that comes with a title.

* During the 1930s and 1940s the ''Tijuana Bible'' phenomenon began to blossom. These were pornographic comic strip parodies of famous characters like Franchise/MickeyMouse and Franchise/DonaldDuck, drawn by anonymous artists. As Creator/ArtSpiegelman has correctly said: "These were the forefathers of the UndergroundComics of the 1960s and 1970s."
* Creator/MarvelComics' Earth-14094, as featured in ''Comicbook/UltimateFF'' is a version of the ''Comicbook/SpiderHam'' universe where the characters aren't cartoony, and all the {{Grimdark}} stuff associated with the Comicbook/UltimateMarvel universe happened to them. The only survivor of its horrific demise was Miles Morhames, the Ultimate Spider-Ham.
