* "Lee" and Smellerbee force Jet into therapy in ''FanFic/TheStalkingZukoSeries'' in hopes of curing his [[StalkerWithACrush obsession]] with "Lee". Getting therapy ends up helping Jet realize that "Lee" is probably not a firebender...[[RightForTheWrongReasons But his uncle Mushi is]] since Mushi is constantly making gallons of tea without firewood and goes [[NakedPeopleAreFunny naked]] in their poorly insulated apartment in the middle of early spring.

[[folder: ''Series/Buffy The Vampire Slayer'' ]]

* ''[[http://members.chello.nl/~jg.temolder1/stories/Chosen_to_Destroy.htm Chosen To Destroy]]'', written as a TakeThat at ''Series/BuffyTheVampireSlayer'' and ''{{Series/Angel}}'', which has the First Evil show up after the Season 7 ''Buffy'' finale, basically to gloat over how it's going to open all the world's Hellmouths and kill all the Slayers in the world, and to rub it in that it's all Buffy's fault - while some of it was the First's manipulations, it makes it very clear that the main reason it's going to win now is because of Buffy's ego and stupidity (and Angel's to a lesser extent).

** In Chapter 7 of ''Fanfic/CalvinAndHobbesIILostAtSea'', Calvin destroys the radio on the ship - their only means of contact with the outside world.
** In ''Fanfic/CalvinAndHobbesTheSeries'', Hobbes and the MTM try to close a hole in reality, and two of their attempts end up making it ''larger''.

[[folder: Cross Over ]]

* In ''Fanfic/{{Kage}}'', the Guardians are quick to attack Jade when she arrives in Meridian, and that, combined with Elyon loosing control and nearly ''killing'' her, is a major part of the reason Jade ends up with the Knights.
* The events of the three-part finale for ''Fanfic/ChildrenOfTime'' are largely due thanks to Literature/SherlockHolmes, Dr. Watson, and teenage [[WesternAnimation/SherlockHolmesInTheTwentySecondCentury Beth Lestrade]]. The friendship between Holmes and Watson has been disintegrating, and the argument that they have early on tears a huge rift in their relationship -- right as one of Holmes's canonical, [[Series/DoctorWho Fixed-Point-in-Time]] cases is beginning. One which Watson ''ought'' to be witnessing. The case goes wrong thanks to Watson not being there and Holmes [[RefusedByTheCall refusing to accept help from Beth]]. To top it off, when Holmes is kidnapped, [[RecklessSidekick Beth follows]] and is caught, herself, allowing the BigBad to realize that she is now a TemporalParadox that ought to be eliminated. [[spoiler:TimeStandsStill, and [[KillTheCutie Beth eventually dies]].]]
* In ''FanFic/ConnectingTheDots'', when Kakashi teleports himself to TheDCAU to try and rescue [[{{Manga/Naruto}} Naruto and the Konoha 11]], he appears right in front of LexLuthor. This is particularly bad as [[spoiler:the Sharingan was the last thing Luthor needed to complete the Anti-Life Equation]].
* Tends to be a habit with [[LeeroyJenkins Naiki Satomi]] from ''FanFic/DivineBlood''. Some specifics:
** Underestimates the Karate Club guys and gets in a position where she has to use a chi burst to defeat them in public, [[spoiler: while Gauron is spying on Kaname nearby.]]
** [[spoiler:Naiki's fear of flying combined with a terrorist takeover of the plane she's on causes her to go on a fear-crazed berserk as soon as the plane lands, which leaves her captured and used as a hostage to insure Deimosu's surrender.]]
** [[spoiler:Goes back to help Kurz's fight against the Venom Chodarl, splitting the escape party and causing Eija, Kaname, Deimosu and Sousuke to hesitate long enough figuring out where she went for the Musk to attack and force Eija, Kaname and Sousuke to miss the escape.]]
** [[spoiler:Tries and fails to rescue and protect Tessa from the Behemoth terrorists.]]
** [[spoiler:Uses a black magic spell that causes her to touch Tessa's soul, starting the mind merge process and also indebting her to a Demon that makes Mara queasy. Twice.]]
** In backstory, Naiki's intense fear of flying is due to an...interesting 10 meter trip through a hangar that occurred when she tried to operate a helicopter as a young girl.
** [[spoiler:In the fight against the Behemoth, uses her summoned tentacles to throw Mao into a pile of debris, almost effectively taking her out of the fight.]]
** In the Martial Arts Takeout Race, loses control of her newly made Torrent of Debris spell.
** [[spoiler: Before getting one of Persephone's peaches, she spends a lot of the fight against Poseidon being rescued by the older, human martial artists.]]
* [[TengenToppaGurrenLagann Nia]][[SonicTheHedgehog my]] of ''Fuck The Jesus Beam'' decides to deal with the Bombignat threat by releasing O.B.A.M.A. from his prison, despite him having started 95 World Wars as president and, as it is later revealed, being the source of the Bombignats. Upon his release, O.B.A.M.A. says that he will reclaim his domain, and takes control of the Bombignats.
* While not much of a hero, Vash of ''Fanfic/ChristianHumberReloaded''[[note]]A crossover between too many works to list here[[/note]] kills a dragon named Le-Hung Doe as part of atoning for killing another dragon, but learns that by killing him, he has started a Ying-Yang War, in which he must fight demons without weapons.
* ''Fanfic/ThePrayerWarriors'' have killed many people in their fights against [[Literature/PercyJacksonAndTheOlympians the Greek Gods]], [[Literature/HarryPotter Hogwarts]] and [[DirtyCommunists Communist Russia]], but it's implied in ''The Titans Strike Back'' that their infiltration and destruction of Hogwarts resulted in many Christian deaths, and now that the school has been re-established, they're going to deal with it differently this time.
* ''FanFic/TheGodEmpressOfPonykind'': Celestia kills King Sombra. [[spoiler: This allows him to ascend and become a Daemon Prince and pull the Crystal Kingdom into the Warp]].
* ''FanFic/{{Horseshoes and Hand Grenades}}'': Ryusei's attempts to save his friend from the coma by killing Gentaro only made Ophiuchus resurrect Gentaro as a Serpent-bearer with a vengeance to kill his former friends. Moreover, [[spoiler: Jiro died anyway, and was resurrected by Gentaro to serve him and kill Ryusei. And that's not talking about how this derailed Gamou's plots for the Day of Awakening and how his benefactor Tachibana--Virgo Zodiarts--has to start injecting Cosmic energy into innocent kids to make up for everything. Was killing Gentaro worth all of this in the end, Ryusei?]]
* In ''Fanfic/TheSwarmOfWar'', after the Kingdom learns about the Zerg and misidentifies them as a Chaos corruption, a decision is made to bring out the hidden superweapon: [[spoiler:hibernating Space Marines. Unfortunately, nine of them ''are'' corrupted by Chaos.]]
* In ''FanFic/TheBoyWithTheMagicNotebook'', Maxwell tries to summon a healing rainstorm to heal people after Shatterbird's attack on Brockton Bay. But while it did heal all their wounds, ''it still left the glass pieces inside them''.
* In ''[[http://www.tthfanfic.org/Story-23085/Chilord+End+of+the+Line.htm End of the Line]]'', Anime/SailorMoon created a magic barrier to protect her hometown from an apocalypse. As [[Series/BuffyTheVampireSlayer Xander]] furiously explains to her and Luna before he kills them, that very barrier is what caused the apocalypse by pulling magic out of everything in the world.

[[folder: ''Visual Novel/Dangan Ronpa'' ]]

* While [[GroundhogPeggySue Naegi]] has plenty of these in ''FanFic/AndAgain'', Monobear explictedly points out one to him near the end: his decision to send the strongest students off to [[spoiler:supervise Mukuro retrieving her arsenal from her room]].
-->'''Monobear:''' What a great idea! Send all the strongest of you bastards away! Defend everyone else with the power to sing and have rich parents! What was your talent again, Naegi-kun: Super High-school Level Strategist?
* In ''FanFic/GraduateMeetingOfMutualKilling'', Tomoe Chiba, ex-SHSL Strategist, was really focused on helping and getting people to help to escape. In her efforts, she gave Matsukaze a signal interceptor for him to use as he wanted. [[spoiler: The interceptor would later cause internal bleeding that kickstarted Matsukaze's death]]. Another action she did was dismantling a Monobear. While it wasn't explicitly said, it's possible that [[spoiler: the screwdriver that ended Matsukaze's life was left there by Chiba after being done with the dismantling]]
* In ''Fanfic/SystemRestore'', in an effort to prevent any murders caused by Monobear's "motive" in the second chapter, the Twilight Syndrome video game that he dares the cast to play, the group comes up with the idea of having people guard the game console. Unfortunately, one combination of guards Hinata comes up with is [[spoiler:Pekoyama and Kuzuryuu]]. Unbeknownst to Hinata, [[spoiler:Pekoyama has been raised to view herself as Kuzuryuu's "tool,"]] and as such, the former lets the latter play the game, leading to the murder of [[spoiler:Pekoyama, by someone hoping to preemptively stop her from killing anyone else]].

[[folder: ''Manga/Death Note'' ]]

* In the ''Manga/DeathNote'' CyberPunk [[AlternateUniverseFic AU]] ''FanFic/AlternativeGods'' [[AggressiveNegotiations L attempts to intimidate Light into working for him by blowing up a building.]] This does not have the desired effect-[[StartOfDarkness by the time L contacts him again Light has drawn up a list of criminals he wants L to punish for him.]]
* In ''Fanfic/LightAndDarkTheAdventuresOfDarkYagami'', the girl from the bus kills Dark and gets hailed as a hero for doing so, but he goes to the Shinigami world after dying, kills Blud and becomes king of the Shinigami. He even thanks her for killing him and enabling his ascent.
* This is the whole premise of the ''Manga/DeathNote'' post-canon fic ''[[http://archiveofourown.org/works/570070 The Second Coming]]''.
* In the [[AlternateUniverseFic AU]] ''Fanfic/{{Seigikan}}'' Light ForgotTheCall (and his hobby of killing people) when he got EasyAmnesia from an accident but later when Light and L have an argument L bashes Light's head against a bathroom sink [[PercussiveMaintenance which causes Light to regain his memories.]]
* ''FanFic/ShadowOfTheValley'' suggests bad things happen after [[spoiler: [[EvilOverlord the only force that is maintaining order in the world]] is killed...]]

[[/folder]]

[[folder: ''Series/Doctor Who'' ]]

* Happens quite often in the ''Series/DoctorWho'' fancomics on Webcomic/RichsComixBlog.
** In ''Webcomic/The10Doctors'', the entire reason the Time Lords lost the Time War is that the Valeyard -- who the Time Lords ''created in the first place'' -- killed Damon before he could give the Daleks' attack strategies to the Eighth Doctor. If this hadn't happened, the war would have been much less destructive, the Time Lords and Gallifrey would still be around, and the events of ''The End of Time'' would never have happened. Essentially, it's the Time Lords' own fault they got into the Time War, which isn't too surprising.
** Later, the Tenth Doctor finds the relevant data spool. He reluctantly decides ''against'' giving it to the Eighth Doctor, in order to keep history on track.
** In ''Outrage'', the Sixth Doctor reveals WesternAnimation/{{Jem}}'s secret identity to Rio Pacheco. Rio doesn't take it well.
** In ''Seeds of Destruction'', the Fifth Doctor lands on a lush garden planet, ignoring Peri's request of Pasadena, California. Said planet turns out to be the deadly planet Kryn.
** In ''A Time To Kill'', the Tenth Doctor completely shatters Film/JamesBond's cover, and the spy is injured in the ensuing fracas.

* In ''[[http://www.fanfiction.net/s/8514012/12/Keena-the-Defendants-of-Constan-Magic-Academy Keena & the Defendants of Constan Magic Academy]]'', main villain Eiko tells Lily that her and Michie can't end up together due to Lily kissing Akuto before ([[ContinuityNod which happened in the actual Demon King Daimao anime]], and Lily only kissed him as a "reward"), as it automatically causes her to be engaged to him due to him being the Demon King. Cue short {{Tearjerker}} and SanitySlippage.

[[folder: ''Franchise/Lyrical Nanoha'' ]]

* ''Fanfic/GameTheory'' has quite a few examples. The two most notable are Chrono [[spoiler:[[PoorCommunicationKills assuming that Nanoha was working with Fate]] and attacking her in her home, which led to her ''actually'' deciding to help Fate fight the TSAB]], and Nanoha's consequent decision [[spoiler:to help Precia revive Alicia.]]

[[folder: ''Video Game/Modern Warfare'' ]]

* In ''FanFic/ModurnWarfare3TheDeadRise'', [[strike:Soap]] Soup throwing a knife into [[spoiler:General Shepherd's eye]] triggers his demonic powers, enabling him to come back even more powerful than before.

[[folder: ''Western Animation/My Little Pony Friendship Is Magic'' ]]

* In ''FanFic/ChroniclesOfHarmonysEnd'', Array conspires with Discord to overthrow [[TopGod Harmony]] (the only force keeping the two of them in line), believing he could destroy Discord himself. [[spoiler:He was wrong.]]
* ''FanFic/InnerDemons'': If Celestia had told Twilight about the prophecy sooner, or broken the news to her differently, it's possible that perhaps Twilight's transformation into the [[SuperpoweredEvilSide Queen of Darkness]] could have been slowed or altogether prevented. [[spoiler: At the very least, Twilight wouldn't have [[FreakOut freaked out]] and turned Celestia to [[TakenForGranite stone]] in a fit of anger at the revelation.]]
** Twilight actually pulls this on ''herself''. After the above incident, she convinces her friends to lock her up in the library basement while Rarity searches for a way to stop her descent into darkness [[spoiler: and free Celestia]]. Unfortunately, since Spike is busy helping Rarity and Twilight's all alone, there's no one to wake her up from her nightmares, wherein the Queen persona consumes her completely.
** A little later on, [[spoiler: Sweetie Belle]] is on the verge of a HeelRealization, when Rarity's unfortunate wording during a conversation hits an emotional trigger [[ManipulativeBastard Queen!Twilight]] had previously planted, causing [[spoiler: Sweetie Belle]] to fully embrace her FaceHeelTurn [[spoiler: and reject Rarity as her sister]].
** Apple Bloom ends up [[spoiler: accidentally killing [[TheDragon Trixie]], whose death [[MoralityChain causes]] Queen!Twilight to suffer a VillainousBreakdown that [[PowerBornOfMadness results]] in her [[OneWingedAngel transforming into an Alicorn]].]]
* There are not words to describe Celestia's epic screw-up in ''Fanfic/PastSins''. Suffice it to say that if she had just held back, almost none of the really bad things would have happened.
** Because Twilight [[HeroicBSOD didn't stop Celestia]], Nyx becomes convinced ''she was in on it''.
* The ''FanFic/PoniesOfOlympus'' series:
** ''Ditzy Don't'': Twilight's attempt to help Ditzy by implanting magical copies of the Mane Six's personalities in her head first causes her to outclass Rainbow Dash to the point of her public humiliation, then all the group's negative aspects (Fluttershy's sudden rage, Pinkie's personalities, Twilight's obsessiveness, etc) take over, making her go crazy and chase after Rainbow Dash to force her to let her take care of her.
** ''Rolling in Beaches'': Wavedancer taking the Rainbow Pearl out of curiosity (and then keeping it to get close to Spike), leads to it being stolen by the Scaly Back River dragons, who in turn break it and accidentally release the [[TheCorruption Rainbow of Darkness]].
** The flashback at the beginning of ''Atlas Strongest Tournament'' incorporates the story of [[http://en.wikipedia.org/wiki/Tithonus Tithonus]], with Celestia as the guilty party.
** When Rarity saw Ran Biao and Razorwing together, she ran away at the perceived betrayal, which led to [[spoiler: Razorwing raping Ran]]. This led to the breakup of their friendship.
* The ''FanFic/PonyPOVSeries'':
** [[spoiler: [[EnemyWithin Fluttercruel]] honestly just wanted to teach Fluttershy something important for her own good, to let her learn the cruel part of nature, but it ends up [[SuperpoweredEvilSide corrupting]] her for real as opposed to being just brainwashed by Discord. Fluttercruel is [[MyGodWhatHaveIDone absolutely horrified]] realizing this.]]
*** [[spoiler: She also gets Fluttershy, and herself, ''[[CantHoldHisLiquor drunk]]'', which WordOfGod admits may have had something to do with their behavior following and made Fluttershy more vulnerable to the darkness than she otherwise would be.]]
** [[spoiler: While it's LooseCanon, it's implied that the Mane Cast are, unknowingly, being manpulated into commanding [[BigBad Princess Gaia's]] army via a boardgame they're playing with Gaia herself. If this is believed, Rainbow Dash unwittingly guides Gaia's army into "Gaiafying" Gilda.]]
*** [[spoiler: If this is true, it is quite possible that Trixie and Twilight Sparkle are unwittingly providing a front for Princess Gaia to ''brainwash their own mothers'' into being her knights.]]
** In the aftermath of a battle, your friend-suddenly-turned-enemy lays indefinitely helpless before your group. To help console each other on this tragedy and related circumstances, one mentions that it is not too late to restore or redeem this friend. If you think that taking matters into your own hooves and [[spoiler: executing your petrified former friend, Discord, by pulverization]] is not a logical next step, you are smarter than [[spoiler: Galaxia, whose deed costs her life, sets the stage for a 1000 years of tyranny, and worst of all, could have been easily avoided.]]
** During the battle between the [[BadFuture Dark World!]]Elements of Harmony and Discord's remaining minions, Spike has to choose between helping Rarity and Twilight, both of whom got separated from the main group while fighting [[PsychopathicManChild Fluttercruel]] and [[TheBrute Angry Pie]] (respectfully). [[spoiler: He figures Rarity will need more help and goes after her; in fact, not only has Rarity by this point killed Fluttercruel, but Twilight ends up overpowered by Angry Pie, who rips out her Element and leaves her for dead.]]
* In ''[[Fanfic/PonyPsychologySeries Secrets and Lies]]'', Twilight tries to prevent Discord from escaping ''without'' alerting anypony who doesn't '''need''' to know what's going on, in order to avoid triggering mass panic. On top of this, she's keeping other secrets from her friends, and her attempts to fix everything without revealing them lead to terrible complications. Her biggest break, however, is when she determines the best way to help Fluttershy [[spoiler:is to have her commited, leading to her getting dragged away kicking and screaming and locked up in a madhouse]].
* In ''Screwball Over'', Twilight Sparkle and friends discover that their attempts to cure their friend and neighbor Button Stitch of her tendency to turn into her ToonPhysics-powered alter-ego Screwball were all part of a plot by Discord to [[spoiler:summon an endless swarm of mini-Screwball clones and swamp Equestria]]. Discord, having been turned back into stone at this point, has left a message mocking Twilight for falling right into his trap with her goody-goody ways. Twilight is only saved from a HeroicBSOD by the reassurances of her friends and the princesses that she shouldn't blame herself.
* ''{{Fanfic/Anthropology}}'': If Lyra didn't want to be a human so badly, Discord would have never found Earth in the first place. Naturally, [[EvilGloating he takes great pleasure]] in [[LampshadeHanging pointing this out to her.]]
* Pulled on the ''readers'' in [[Blog/ReadingRainbowverse Dungeon Master Bonbon.]] When Lyra temporarily takes over the blog, they spam her with asks saying how Bonbon loves her, causing her to ''break up'' with Bonbon out of fear she's leading her on.
* In ''[[Fanfic/AVoiceAmongTheStrangers A Stranger Among the Voices]]'', Twilight and her friends have an offscreen incident early in the story that involved repelling a chimera and forcing it back into the Everfree Forest. At this point, the reader can guess this is the same chimera that attacked Dinky in the previous chapter, which wouldn't have happened if Twiilght's timing had been a bit later, as she notes to herself.

[[folder: ''Naruto'' ]]

* ''Escape from the Hokage's Hat'' has Shizune not let a recovering Naruto (who just wants to provide support) fight by slapping him with a InterfaceScrew jutsu. This ends with Hinata (literally) getting stabbed in the back, Shizune too tired to heal Hinata while the enemy attacks, Naruto using a ForbiddenDangerousTechnique that could've fried his charka network to save them and her losing Naruto's trust. She, however, at least notes how she screwed up and starts fixing the mess.

[[folder: ''Franchise/Pokemon'' ]]

* In ''FanFic/CloudedSky'', it turns out that [[spoiler:Waytar's Shield was keeping all of the ghosts in Waytar trapped there]], and by destroying it, Tobias sets them loose on the outside world.
* When [[FearlessFool Colby]] of ''[[Fanfic/PlasmasFolly Plasma's Folly]]'' smashes Lynn's C-Gear with a rock to keep her from calling for backup, Lynn declares that she'll just have to kill Destiny and Aurelia then and there.

[[folder: ''Franchise/Star Trek'' ]]

* {{Discussed}} in ''Fanfic/TheWrongReflection''. Gul Morag of the Klingon-Cardassian Alliance in the mirror universe blames Starfleet for the resurgent Terran Empire. It's mostly accurate,[[labelnote:*]]although note that Starfleet wasn't responsible for James O'Brien killing Mirror Miles O'Brien and going back to the BadOldDays[[/labelnote]] but Captain Kanril Eleya refuses to be held responsible for it because all it happened before she was born and Julian Bashir and Kira Nerys were only doing what they had to do to escape Alliance imprisonment. Still, it ''is'' the fault of the prime universe Ferengi that the Terrans now have cloaking devices, something which Eleya fixes by giving the Alliance Starfleet's data on how to ''defeat'' a cloaking device.

[[/folder]]

[[folder: ''Video Game/Touhou'' ]]

* '''Everything''' in ''FanFic/ImperfectMetamorphosis'' can ultimately be traced to Team 9, and Cirno specifically. They were responsible for both releasing [[spoiler:the Shadow Youkai]] and getting Yuuka involved, and their constant meddling continued to make things even worse. Other characters caused a lot of headaches too (especially Eirin and Yukari), but only Marisa, due to having stolen the box from Patchouli in the first place, allowing Team 9 anywhere near it, is anywhere near their level of blame.

[[/folder]]

[[folder: ''Manga/Tsubasa Reservoir Chronicle'' ]]

* When Fai finds out about [[spoiler: R!]]Syaoran and Kurogane's SecretRelationship and the fact they were sleeping together in ''FanFic/{{Shatterheart}}'', he forces an ultimatum for Syaoran to either to tell the truth to Sakura or to break up with Kurogane, which he sees as extremely codependent. This has the side of deteriorating Fai's budding reconciliation with Syaoran. His earlier ostracization and hatred of the latter and forcing him to end his only positive relationship proves the straw to break the camel's back and Syaoran wants nothing to do with him. Since Kurogane was the only one Syaoran could turn to for comfort, his PTSD gets worse and he mentally and emotionally falls apart.

[[folder: ''Literature/Twilight'' ]]

* Okay, ''Fanfic/{{Luminosity}}'''s only difference is that Bella's a different character, so naturally the differences for good or ill will be her fault...village murdered because of her? And now [[BigBad the Volturi]] have [[SuperSoldier shapeshifters]] on their side? Because Bella thought it would help them. Oops. And Elspeth is following in her mother's making-the-Volturi-stronger footsteps.
