Perhaps the actions of the lead characters demonstrated Moral Dissonance. Perhaps there was a moment in which the canon author sided with the hero but the Fan Fic writer didn't. Perhaps it's Values Dissonance between the author of the canon and the fanfic writers.
It doesn't matter where the original wrong lies — whether it's a misguided author or a Misaimed Fandom. The result will be a plot in which the canon events will be deconstructed, or the results of the events turn dark. A careless author will use Diabolus ex Machina for this; a clever one, using suitably flawed material, will make the consequences seem natural, or plausible if we've hit an Alternate Universe Fic, which it often will be if the canon is long-running and the fic is about an event set midway through the run.
There will be negative consequences for the characters who did the perceived wrong. There may or may not be negative consequences for innocent characters, depending on how cruel the author is feeling.
Naturally, this sort of fic will tend to be a Dark Fic.
If the canon events in question are required by the Anthropic Principle, then the fic is a Hate Fic; but not all Accusation Fics are Hate Fics. An Accusation Fic can overlap with a Betrayal Fic, but not all Betrayal Fics are Accusation Fics. A good rule of thumb is that if the fic you're reading spends most of its time taking the wrongdoing characters to task on how they messed up, then you're reading an Accusation Fic. If the fic spends most of its time on the character who was wronged, then you might have a Betrayal Fic.
Examples of Accusation Fics from the following media:
- Several Love Hina fanfics focus on punishing the cast for their self-centered attitudes and over-the-top abuse of Keitaro.
- An Alternate Keitaro Urashima has Granny Hina taken to task for enabling the girls' issues instead of helping them work through them, and for abandoning them so she can enjoy her world tour. The girls also have to face realistic consequences for their normal antics, such as Naru risking expulsion when she attacks Keitaro at their cram school, or Mokoto getting arrested for threatening him with her sword.
- For His Own Sake includes Keitaro and Mutsumi along the cast members getting called out. Having spent three years trying to manage the Inn before giving up at the start of the fic, Keitaro is taken to task for being such an Extreme Doormat and enabling the girls' bad behavior, while Mutsumi keeps shipping Naru/Keitaro against their will.
- Mad King Zoisite plays this for laughs, with Zoisite surviving Beryl's attack on him and being pissed off at Kunzite for making him do most of the work for their mission.
- Infinity Train: Blossoming Trail spends its first chapter setting up for Chloe's departure on the Train by delving into how she feels isolated due to her lack of interest in Pokémon, and how much she's come to resent the way that her Childhood Friend and father care more about Pokémon than they do about her. This culminates in a furious confrontation where she takes them to task for their neglect before running away. Chapters later, Goh chews out all of Chloe's classmates who pressured her into doing something she didn't like and were more focused on Chloe fighting Ash than the fact that she's been missing for about a week. Most notably, the student that takes the heat is the student Yeardley (the only named student in Chloe's class from the anime) who the author notes that the writers used him to make a Double Standard that a boy doesn't have to be pressured on who he wants to be, but the girl (Chloe) and her life choices has to be decided by her peers.
- Many (if not all) Maribat AU fics call out Mme. Bustier's class for their actions towards Marinette.
- Ms. Bustier is seen as an an utterly useless teacher by the Wayne Enterprises staff and Wayne family because her nonchalance towards Marinette being left behind despite the fact that she is a minor left alone in a city as dangerous as Gotham. They also notice how Mme. Bustier doesn't stop the obvious bullying of Marinette by the class.
- Most of Marinette's classmates are portrayed Gullible Lemmings who easily turn upon their 'Everyday Ladybug' thanks to Lila.
- Only Chloe is excluded from this. Sometimes a few classmates get wise to Lila's lies before the start of the (or during the) fics and support Marinette. They are usually Juleka, Kim, Alix, and/or Max. Rarely, it's sometimes Adrien.
- Alya goes from Marinette's best friend to being the Beta Bitch to Lila's Alpha Bitch, becoming a miserable bully.
- Adrien/Chat Noir's Entitled to Have You behavior towards Labybug and/or Marinette is taken to a disturbing level. His 'high road' approach of doing nothing and blaming Marinette for standing up to Lila is seen as cowardly and self-serving by both Marinette and the Wayne Family.
- In Yu-Gi-Oh! ARC-V, Yusho Sakaki ends up getting away scot free for his journey into the Xyz Dimension for three years, not caring that his son went through psychological trauma and becoming a Stepford Smiler/Sad Clown, his school fading into nothingness and people mocking him for being a coward. Between My Brother And Me Mors Omnibus has Yusho called out for plenty of people for his negligence of not saying goodbye to his son and wife, not telling them what was going on, not telling Reiji to help Yuya/Yoko/the school out. It gets to the point that Yvonne, Ruri and Zarc tell him that he's made very stupid decisions. Reiji also is to blame too since he goddamn told Yusho about everything and never really cared about Yuya unless it was beneficial to his plans and Yusei wastes no time telling Reiji that he's just like his dear old dad.
- In Doctor Who, it's licensed! Many Expanded Universe novels during the hiatus have pretty much everybody, up to and including his past and future selves, mercilessly let the Seventh Doctor have it, sometimes going past What the Hell, Hero? and right into Revenge Fic. Why the hate? Well, Seven was The Chessmaster, and sometimes used his friends as pieces on the board when absolutely necessary, and this was seen as being a callous jerk by many. Though the Ninth, Tenth, and Eleventh Doctors that came after the end of the hiatus have their own shades of grey and skeletons in their closet, they are frequently called out for such behaviour, and the Doctor is referred to by several characters — both good and bad — as being unsafe, blood-stained, and followed in his wake by death, even referred to as the "Trickster" or "Goblin" in the legend of the Pandorica.
- Angel has a canon example of this trope in the Season 5 episode "Damage". Angel and crew get called out by AndrewWho? of all people for the morally questionable move of taking over Wolfram & Hart and the resources the evil law firm provides.
Andrew: (to Angel) News flash — nobody in our camp trusts you anymore. Nobody. You work for Wolfram & Hart. Don't fool yourself... we're not on the same side.
- Both Tony DiNozzo and Tim McGee are common focuses of this in NCIS fic, based on the various ways they have been mistreated by the other members of their team. The most common theme in Tim-centric fics is the aftermath of the dog attack in "Dog Tags", while Tony's usually focus on Tim and Ziva turning his radio down in "Dead Air" leaving him without backup while he was undercover.
- Because of the grand scale of action on Supernatural sometimes a character takes an action that affects the whole group, but not everyone is aware of it.
- In fan fic, Castiel is called out for releasing Sam, which triggered the events that led up the Apocalypse. In canon, neither brother is aware of this and Castiel never mentions it, although he tries to atone for it through his actions. In fan fiction, however, he is forced to admit and be chewed out for his role in the destruction it caused.
- Although Dean chews Sam out for it multiple times, about three years pass between the time Sam fails to search for Dean in purgatory in season 8 and the time he apologizes for failing to do so in season 11. The action is so Out of Character that there is a great deal of fan fic that explores Dean being angry and Sam being immediately and genuinely remorseful.
- Although Dean expresses remorse in the series and Sam is rightfully upset, a large chunk of fan fiction delves further into the angst they feel the brothers should have experienced when Dean tricks Sam, who has a long history of being physically violated, into being possessed by an angel who turns out to be a villain.
- Redress has its version of PMD Explorers's hero call out Chatot in Brine Cave for his mishandling of the Perfect Apples incident.
- Super Robot Wars Z2: Saisei-Hen did this with Ougi's decision. Schneizel reveals to the Black Knights and ZEXIS the true identity of Zero a.k.a Lelouch vi Britannia and tells them about the properties of Lelouch's geass. It gets worse when an angry Ougi appears after hearing everything about Zero from Villeta.
While the majority gets manipulated into believing what Schneizel says, only a handful of people (Sumeragi, Roger, Heero, Chirico) are able to see through Schneizel's plan and deceit. When Zero arrives, the Black Knights are prepared to pounce on him like in the anime but some members of ZEXIS (Sumeragi, Roger, Heero, Chirico, Crowe, Simon, Viral) tell the Black Knights to wait and give Zero a chance to explain his actions.
If the player has managed to obtain enough Zero points, Ougi will have the option to believe or not to believe in Zero. With Ougi deciding to give Zero a chance to explain his actions and the betrayal of the Black Knights being averted, an embarrassed Schneizel has no choice but to leave peacefully. Zero then removes his mask and starts explaining his actions to everyone.
- Fire Emblem:
- A Fire Emblem: The Sacred Stones fic, In Questioning Ghosts, has Eirika unable to explain Lyon to the people without calling him on every mistake he made and in the end being unable to ever forgive him.
- Another fic for Fire Emblem Awakening deconstructs Chrom's ending, in which a male Robin expresses his anger towards Chrom for not letting him deal the final blow to Grima, citing that it was not Chrom's decision to make and that he was selfish for doing it. He ends up sneaking off by himself to end his life as well as Grima's, and Chrom is left to suffer the damages and consequences of his choice.
- Senbonzakura, a post-Conquest route Fates fic, presents Sakura as being far more resentful towards Corrin over his choice as a way of the author addressing their problem with Conquest!Corrin's choices and actions.
- The Persona 3 fanfic Second Time's The Charm has Yukari (like the author) getting fed up with Aigis repetitively and hypocritically reminding her that Ryoji (Yukari's boyfriend in this fic) is dangerous and saying "Well, so are you, yet we still keep you around. Goes to show it doesn't really matter, does it?"
- Super Mario Bros.: Invisible: From the Desk of Princess Daisy is a fic where Daisy is Driven to Suicide because she thinks no one wants her around and that her friends find her annoying. It is a Take That! against how the franchise regulates Daisy to spinoffs. In the end, Daisy wakes up from a coma. Peach tells Daisy that she was wrong, that her friends do like her.
- In Lilo & Stitch: The Series, the eponymous girl and her illegal genetically engineered alien are tasked with capturing the other 625 experiments and re-purposing them before the bad guys get to them. However, some would be obtained by the bad guys in order to create tension and not make the heroes seem completely undefeatable. Some fans cried foul about how Lilo appeared to seem to just let some of the captured experiments go. Experiment 166: Fury (which may in fact be the first Accusation Fic, depending on how old the genre actually is) invents a specially-made fan experiment that calls Lilo out on this, and at the end, she and the others go and rescue the until-then captured experiments.note

- Stormbenders was written by an author who believed Aang wasn't a true hero, that he was selfish and refused to grow up and change, and thus painted him as an unsympathetic child. In her view, it was Zuko who was the Real Hero (and more importantly, deserved Katara's love more).
- On a lesser scale, An Aging Ideology has Sokka calling Aang out for his refusal to kill Ozai in the finale.
- The Stalking Zuko Series also has Katara calling Aang out on not killing Ozai, and the implication that he is hypocritical for not killing Ozai, but sinking Fire Nation ships while fused with the Ocean Spirit. The author's ultimate goal as far as Aang's character arc goes is to give Aang Character Development that he never got in canon, particularly the realization that he isn't always right, and as such, very few of Aang's major decisions pass without scrutiny or criticism.
- Vathara's one-shot, Theft Absolute, points out how stupid it was for Zuko to steal that ostrich-horse in "The Cave of Two Lovers". ("What will bring news to [Azula's] ears more swiftly, nephew? Two refugees who leave in the night... or an ostrich-horse thief?") This one-shot would then go on to form the basis of Embers.
- The Legend of Korra:
- There are many fics, such as this one, where Kuvira calls out Suyin for being a bad foster mom who didn't treat her like a daughter. It should be noted that while Suyin being Kuvira's foster mother is a popular interpretation of their relationship, the show itself never explicitly states it, while the comics would later reveal that it was more of a close teacher/student bond (at least on Suyin's side of the equation).

- The My Little Pony: Friendship Is Magic fandom has so many, there's a collection for it. Here are some notable ones:
- Multiple fanfics set after the Canterlot Wedding finale call out almost everyone in the fore for the stuff they did. Twilight for accusing the false Cadance with a lack of information to back her claims, her friends for ditching her in her time of need, Shining Armor for disowning his sister (though whether he did that himself or was mind controlled into doing so is up to the writer), and Celestia for choosing her niece's comfort over the safety of her people. Most, if not all, Accusation Fics focus on calling out Twilight's friends for ditching Twilight, but there are some that accuse Celestia and Shining Armor for failing to protect Canterlot from the threat they had received. In fact, in one fanfic, it becomes fuel for an Anti-Celestia rebellion. A Canterlot Wedding Aftermath is another one where Twilight is traumatized with nightmares. Many fics also have the real Cadence finding out what happened at the rehearsal and calling out everypony for how they treated Twilight, some having her break up with Shining and call the wedding off altogether.
- Setting these in the aftermath of "The Mysterious Mare-Do-Well" is also common. What's Eating Rainbow Dash?, for instance, lays the blame primarily at Twilight's hooves, painting her as unaware that publically humiliating Dash would have long-term consequences, to the point that Dash nearly leaves Ponyville.
- More than a few have popped up regarding the Wonderbolts, particularly in light of their appearances in Wonderbolt Academy, Rainbow Falls, and Newbie Dash. The Quiververse story "A Light in the Dark" has a potential Wonderbolt recruit go so far as to tear up her application to join in Spitfire's office and then angrily chew her out for her leadership style and willingness to abandon her comrades.
- "...That's It?" is an example showcasing an alternate version of "The Cutie Remark" two-parter where Starlight Glimmer tells Twilight Sparkle her Freudian Excuse and reason to time travel and Make Wrong What Once Went Right... and Twilight becomes Disappointed by the Motive (not surprisingly, considering that Starlight made a lot of Bad Future Alternate Universes — one of which is essentially the canon version of Fallout: Equestria — just because her friend got a Cutie Mark before her) and completely tears into Starlight with a "The Reason You Suck" Speech.
- There was once a popular accusation fic community for the Season 3 finale "Magical Mystery Cure" in which Twilight calls out Princess Celestia for imposing her "destiny" to become an alicorn princess on her when she already learned during the episode that it is wrong to have a destiny imposed on you. These fics often have Twilight rejecting her alicornation and princesshood, and either end with Twilight reverting back to being a unicorn, or Twilight being dismayed with her transformation being permanent. These have died down since the show made it clear she's not going back to normal and is in fact quite happy with her transformation.
- There are a ton of these fanfics (Such as Bitter Tears: An Anon-A-Miss Fic) written in reaction to the Anon-A-Miss incident from the Equestria Girls Holiday Special, to express the fans' disgust with how quick the Humane Five were to abandon Sunset on flimsy evidence, or how petty and spiteful the CMC's reasoning was for framing her, and how easily they got off punishment-wise for they did.
- RainbowDoubleDash's Lunaverse got one to its own Season 1 Finale, Grass&Clouds2's After The Night which starts with Pinkie Pie confronting Trixie over her actions at the very end of AtGGG. It caused quite a stir.
- Twilight's behavior in "No Second Prances" led to a few accusation fics. One, Her Life Was In Your Hooves, has an uncharacteristically upset Celestia call out Twilight for almost driving Trixie to suicide.
- The Great Breakout calls out the princesses for sending a foal to Tartarus without even a trial at the end of season 8. Cozy Glow is just a very troubled, immature child who needs therapy more than anything. When her parents can't convince the princesses to let their daughter go, they break into Tartarus themselves and get her out.
- On that note, A Discussion on the Benefits of Murdering Small Children has Starlight calling out Twilight about Cozy Glow being permanently Taken for Granite in the series finale, equating it to the straight-up execution of a child.
- A lot of Meg-centric fic for Family Guy involves this trope, with the Griffins and other antagonists of her being ripped a new one for their behavior. On the non-Meg front, we have Payback from a Pipe, in which Stewie calls Quagmire out on his hypocrisy regarding his own accusations towards Brian.
- Teen Titans:
- The episode "The Beast Within" featured Beast Boy becoming more aggressive after being doused in chemicals, eventually culminating into him turning into a mindless beast, and being found with an injured Raven's cloak clutched between his teeth. It looks like he hurt her, but Beast Boy just can't remember what happened. Robin tells him that if he can't remember, then he has to assume the worst and he'll have to take him to jail. While it was a bad situation, a lot of fans don't feel that Robin handled it well, and it ends up causing Beast Boy to undergo another stress-induced transformation. While not super-common, there are some fics where Beast Boy or another Titan will call Robin out on how he acted.
- The End of Ends calls out the Titans, The Doom Patrol, and Terra for all the "wrongdoings" theyve done to Beast Boy, although, in an odd twist, Beast Boy is the only one who dies after a stint as the supervillain Count Logan, with the implication being that the surviving Titans and Terra have to live with what they did. The author, Dakari-King Mykan (of My Brave Pony: Starfleet Magic infamy), even has a name for this kind of fic: "Punishment Fics".
- The Winx Club fic Promises of Protection has Timmy snap and shriek blame at Bloom for all the hardships Tecna ever had to face, up to and including her being frozen by the Trix and having her wings torn out. It's only a small portion of the story, thankfully; the rest of it is about Tecna and Timmy vacationing in a peaceful realm.
- With This Ring, a Young Justice Self-Insert Fic, calls out the League on how they fumbled with Superboy: while Paul admits that Superman doesn't have to get involved, it doesn't excuse how no one bothered to check up on him. OL had Miss Martian check Superboy's mind for implanted triggers and help integrate his psychically implanted knowledge. It's only through Orange Lantern, Miss Martian, and Wonder Woman's efforts that Superboy isn't the maladjusted, angry mess that he was in canon.
- The League gets a massive call-out for their mishandling of the CADMUS investigation.
- OL and Zatanna lose faith in the League when they had to find out from the news that Nabu, the creature that kidnapped Zatanna's father, is being allowed into the League.
- The Kim Possible fic "Maslow" presents a more detailed view of Drakken and Shego's relationship, with some of the things they've done to each other during the series being treated seriously instead of comedically, with realistic anger, hurt feelings, and strain on their partnership.
- Steven Universe:
- The oneshot Unlucky Jasper is one towards "Change Your Mind" and the general treatment of Jasper. It has a depressed Jasper calling out the Crystal Gems for not sympathizing with her more and instead trusting her abuser Lapis. Jasper then shatters her own gem in front of Steven, Lapis, and Amethyst because she has nowhere to go and no one to support her.
- Flawed Crystals is targeted at Steven. The final arc takes him to task for his callous and self-centered behavior during the final episodes of the show, especially his desire to save and reconcile with the diamonds at the expense of their victims.
- Miraculous Ladybug fanfiction of this kind has erupted at such a colossal degree following certain controversial plot moments in Season 3, that they have gotten a collective designation: "Salt Fics". Examples include the following:
- The LadyBugOut AU begins with Alya getting called out on posting the photo she took of Ladybug and Chat Noir kissing under Oblivio's influence to the Ladyblog, deliberately omitting the context and ignoring how Ladybug protested. Alya refuses to acknowledge that she did anything wrong, spurring Ladybug's decision to start her own blog. Several other entries in the series center around characters getting taken to task for their decisions and having to deal with the consequences.
- Missing (Miraculous Ladybug) has Marinette go missing after Ladybug is hit by an akuma that makes its victims disappear, unintentionally wiping away the superheroine's Secret Identity. In her absence, those who knew her come to realize just how much they took her presence for granted, with those who betrayed her trust getting hit the hardest by guilt and grief.
- Burning Bridges, Building Confidence treats most of Marinette's classmates (sans Chloe) as Gullible Lemmings who easily turn upon their 'Everyday Ladybug' thanks to Lila. Several individuals are hit especially hard:
- Alya goes from Marinette's best friend to Lila's personal enforcer, becoming a miserable bully helping spread Malicious Slander and even openly assaulting them in class (at one point tearing into Cole's face and popping open the stitches of her missing eye with sharpened nails).
- Ms. Bustier proves to be an utterly useless teacher who joins in blaming Cole and Marinette for the drama in her classroom, even going so far as to blame Cole (along with denying her medical treatment) for reflexively punching Alya after she assaults her. She winds up getting suspended from her job for it.
- Adrien is taken to task for standing by and letting all this happen, despite his claims that he and Marinette would face this together. His 'high road' approach of doing nothing and blaming Marinette for standing up to Lila is called out as cowardly and self-serving.
- In the Star vs. the Forces of Evil / SCP Foundation crossover fic Cleaved AFTERMATH, Star and Marco are captured by the SCP Foundation who inform them about the damages they've caused, from the destruction of magic to the deaths of the Magic High Commission.
