Disproportionate Retribution/Fan Works

• In My Immortal, "Samoro" (allegedly James Potter) and "Lucian" (allegedly Lucius Malfoy) are in a band together. Lucian plays a few wrong notes during a concert, and Samoro responds by attempting to shoot off Lucian's arm. But it was later revealed that Snap(e) used Demonic Possession on Samoro to make him do the above, meaning this trope is subverted.
  • Not to mention when Ebony's friend Willow becomes a 'prep', she is then murdered and her body is dumped in the woods. And is raped by 'Loopin', because he's a 'necphilak'.
  • There's also the time Ebony and Satan start to have sex with each other in a movie theater while the movie is playing. When the woman seated behind them complains, Ebony retaliates by killing her and sucking all her blood. (Well, she is a vampire.)
• Remember in Harry Potter when Ron and Harry were having an argument, because Ron was feeling Overshadowed by Awesome and he felt Harry was hiding something from him? Well, Rose Potter responded to this by throwing Ron around the room and carving words into his forehead.
• In the House Fanfic "Used", Tritter uses kidnapping, gang-rape, murder, stalking, and beating House half to death with his own cane to get revenge for the thermometer incident.
• Tends to be a trend with Post-Kickassia fic where Critic is concerned. Yes, we know he was an epic dick during that week, but is it really necessary to make him the recipient of a dub-conny gangbang?
• In Christian Humber Reloaded, the main character goes after and kills a hunter who set a trap that he stepped into, even though the trap broke on his leg. He later kills his friend Soku, her entire family and all her friends because she turned him in to the police.
• In Latias' Journey, the Ghost King proposes to Latias after sending her several gifts. She refuses his advances, so he kills her family, and then destoys her home, Altomare, along with everyone in it. Judging by the city it is based on, he killed upwards of 800,000 people. Strangely enough, she still falls in love with him.
• In the Poke Wars series, Ho-Oh sees genocide as a fitting punishment for humanity's "enslavement" of Pokémon.
• In Renegade, the Global Defense Initative uses this as a basic part of their military doctrine. If someone fucks with a GDI colony, their response is to utterly destroy whoever attacked them with overwhelming force. This doctrine lead to them obliterating the pirate bases at Torfan from orbit, and results in full-scale war with the Batarian Hegemony due to them supporting attacks on human colonies. One Citadel politician accuses GDI of "making an example" out of the batarians, which GDI pretty much agrees with.
• In Son of Apophis, a Yu-Gi-Oh fanfic, the villain gives a speech about how pointless the whole 'eye for an eye' thing is. It's better to take both eyes, and the other guy's arms while you're at it.
• The 'financialcrisis gangbang' comics in the Axis Powers Hetalia fandom. I mean, really - was raping America really the best way to sort out the financial crisis?
• Most of the main cast in Dragon Age the Crown of Thorns, and some others, feel that the DN protagonist lashes out at Isolde a bit too strongly, although, true enough, she did outright accuse him that he doesn't mind killing children. Basically, he makes her cry with "The Reason You Suck" Speech and even deliberately makes her think he is going to/did kill Connor. Fortunately, he'd only gone upstairs to give the kid a hug and a So Proud of You, plus talk to the demon possessing him face to face.
  • When Connor is finally exorcized, the DN gets quite angry at Alim's impersonation of the Grim Reaper and, instead of congratulating him and whatnot, drags the mage over to give him a What the Hell, Hero?? rant in private. Alim counters it by calling him out on how he reacted too harshly, showing off his own Guile Hero traits by perceiving one of Raonar's biggest regrets.
• Hey kids, is the nerd asking questions that the teacher holds off recess to answer? That's not cool! Let's trick her into going into a forest full of hungry monsters to an ancient and quite possibly cursed ruin where she'll get mind raped by memories she didn't know she had! Sound harsh? Diamond Tiara and Silver Spoon did it! Although, to be fair, they didn't know that the mind rape thing would happen. The monsters, on the other hand, are common knowledge.
• A rather brutal example occurs in the Kids Incorporated fanfic, "The Kids Who Cried 'Ouch'", an answer fanfic to the episode "The Boy Who Cried Gorilla." In the fanfic, Ryan, Connie, and Renee get their "just desserts" for their initial treatment of Richie when he first sees the gorilla. Among other things, Ryan gets beaten to the point that he suffers a drug addiction that causes his grades to fall to flunking levels, Connie gets a knife up the vagina rendering her sterile, and Renee winds up repeatedly getting raped to the point that she winds up pregnant and ends up suffering a miscarriage.
• Inverted in With Strings Attached. Because the four are Actual Pacifists, when they are treated very badly (even tortured in a way) by the Uneasy Alliance in Ehndris—at one point, part of George's soul is taken from him—and have a chance to get some of their own back, they just slap people around for a few seconds. The worst that happens is a few people get slammed into a wall or hosed down, and George does “cat tornado” on Brox's head.
  • It's even more disproportionate when you realize that George did nothing else during the final battle except try not to get hurt, and Paul did nothing except absorb damage and hold Kerrun upside-down and tap her head on the floor to keep her from concentrating.
• Turnabout Storm shows murder as a very rare and serious crime in Equestria, and the punishment for the guilty is banishment... to the Moon or the Sun. Upon hearing this, Phoenix Wright immediately takes it as going a bit too far. Oh well, more reasons for him to bring his A-game to the trial against his new client Rainbow Dash.
  • Then there's Trixie, who took the job as the prosecutor as an opportunity to get revenge on Twilight, so she basically wants to get one of her friends killed because Twilight humiliated her before... Yep, Trixie seems to have taken retribution lessons from Manfred Von Karma.
• One conclusion to the My Little Pony Friendship Is Magic Dark Fic "Pattycakes"^[1] ends with Fluttershy singing to Rainbow Dash about how Dash^[2] will never hurt anyone's feelings again now that she's been mentally regressed to an infant. The other conclusion has Scootaloo fail to grasp Fluttershy's philosophy after going through the series of (twisted) tests, and if she fails the final test by drinking water instead of milk, she's regressed even further than Dash (Dash had Baby Talk, Scoot loses the power of speech entirely), with no hope of ever recovering. (For your daily humour-so-dark-light-cannot-escape-its-surface needs, her cutie mark takes the form of a baby's pacifier, since she's not exactly going to have the chance to demonstrate any other talents, now is she?)
• In the pornographic Sesame Street (no, really), Maria responds to Elmo peeping on her and lying about being three years old for years by diapering him, and taking his temperature with a rectal thermometer, with several ove the other girls joining in the latter, groping his penis in the process. In response, Elmo ejaculates into her, getting her pregnant (because monster sperm gets people pregnant without fail), and tells her that if she doesn't want her husband Luis to find out, she and her 14-year-old daughter will have sex with him whenever he wants.
• In Naruto Veangance Revelaitons, Ronan, who is incredibly homophobic among other things, kills a gay man for merely liking his penis. He also considers Sakura cutting off her own vagina appropriate punishment for cheating on him, although she was the one who proposed it.
