* Used as a SecretTestOfCharacter in an episode of ''WesternAnimation/AdventureTime''. After Finn saves a trio of gnomes from a fire pit, they go on a sudden old-lady killing spree, claiming every action of Finn's as justification for the death of additional old ladies. Jake reseals them quickly and delivers a surprisingly straight Aesop (for this show, anyway) to Finn: aside from the fact that the old ladies were fake, the gnomes acting like jerks is in no way evidence that Finn isn't righteous.
** Used again in season 4 Finale. [[spoiler: Finn collects all the crystals of power in Ooo so Billy the Hero can push the Lich into the portal the Enchiridion will open when the crystals are put inside. It turns out the Lich had possessed (and possibly killed) Billy, and the episode ends with Finn and Jake in the mirror world seen in King Worm]] Wonder how they'll fix that!
* ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'': Used in nearly every Jimmy Neutron episode, and all of the movies. Jimmy's [[InsufferableGenius blinding arrogance]] has even resulted in [[SavingChristmas Christmas nearly getting cancelled]]!
* ''WesternAnimation/ArchiesWeirdMysteries''.
* ''WesternAnimation/AvatarTheLastAirbender'', season 2. Politically destabilizing [[GovernmentConspiracy Ba Sing Se]] may have felt right, but it was a very, very, bad idea.
** Then a few episodes later, Katara sees Zuko [[VillainsOutShopping serving tea]] and instantly runs to inform the authorities. If she had investigated further, confronted him herself or thought about the situation for more than a second, Zuko never would have been put in a position to turn to Azula's side to begin with. (And Aang probably would have finished his last chakra.)
** The "Gaang" in general could've seen the Kyoshi Warriors and made sure that it was them. Otherwise, they would've realized that it was [[DressingAsTheEnemy Azula's group instead]] and they wouldn't have learned about the invasion plan.
** In the battle for the Northern Air Temple, the Mechanist deploys a balloon to defeat the attacking Fire Nation forces, but the balloon crashes. The retreating Fire Nation forces take the balloon and are able to mass-produce balloons and zeppelins to augment their military.
* ''WesternAnimation/TheLegendOfKorra''
** In the episode "Beginnings", Wan sees two massive spirits fighting and threatening to destroy a valley. One begs Wan to help him, while the other tells him to stay out of their conflict. Wan breaks the two up, but it turns out that the spirit that he freed was Vaatu, spirit of chaos and darkness, who goes on to start a massive war between spirits and humans and will bring about TheEndOfTheWorldAsWeKnowIt if he isn't stopped.
** It appears we have another one at the end of season 3 with Tenzin telling Korra [[spoiler: to just take her time and recover while he and the other airbenders keep the balance in her place. In trying to comfort Korra and support her in her time of need, Tenzin actually confirmed her worst fears that the world no longer needs her and the Avatar]].
** Season 4 gives us a WellIntentionedExtremist variant with [[spoiler:Zaheer. Politically destabilizing [[GodSaveUsFromTheQueen the Earth Kingdom]] may have felt right, but it was a very, very, bad idea]].
* The premise of ''WesternAnimation/TheAdventuresOfPussInBoots'' involves the hidden city of San Lorenzo, no longer hidden because Puss-In-Boots took a coin out of the treasury. Dulcinea guilts him into staying to protect the city from all the thieves that will now come as he is the reason they need to be defended in the first place.
* In ''WesternAnimation/TheAdventuresOfSuperMarioBros3'' episode "Seven Continents for Seven Koopas", the Koopalings take over Earth. What does Mario do to undo these actions? Turn the Great Wall into a dragon, and flood the Louvre.
* In episode 2 of ''WesternAnimation/TheAmazingChanAndTheChanClan'', the kids successfully rescue Boo Blew from kidnappers...only to discover they've nabbed a lookalike who didn't ''want'' to be "rescued" ''and'' blown his cover as a double for Mr. Blew.
* In the ''WesternAnimation/AmericanDad'' episode "For Black Eyes Only", the main antagonist's plan is to buy several tons of sand and thousands of hair dryers so he could melt an ice cap, then have the resulting water slightly flood Detroit so his home can become beachfront property. The only thing preventing the resulting tsunami from hitting the US is that he unplugs the hair dryers at the last second; [[IdiotHero Stan]] replugs them and the tsunami hits, resulting in half the US being underwater and millions of lives lost, including the president.
* In ''WesternAnimation/BatmanTheBraveAndTheBold'''s AnimatedAdaptation of ''ComicBook/EmperorJoker'', Bat-Mite tries helping out on Batman by giving all his powers to him in the fight against ComicBook/TheJoker, even though Bat-Mite is warned not to use his powers. However, [[InvisibleMeansUndodgeable he kinda miscalculates on his aim]] and accidentally gives all his powers to Joker, turning him into a {{Reality Warp|er}}ing {{Mad|God}} GodEmperor; and from that time on everything is going to hell when he recreates the universe in his own image and then starts killing Batman and bringing him BackFromTheDead repeatedly, [[DeathMontage over and over again]].
* ''WesternAnimation/Ben10AlienForce'' has an example of this in "Time Heals". Gwen successfully goes back in time and prevents Kevin's monstrous mutation ...[[spoiler:only for her to find out that her meddling in time has caused a BadFuture were Hex rules the Earth, Kevin's Charmcaster's slave, Ben's chained in a dungeon as Hex's prisoner, and ''she's dead''.]] It gets worse when you realize that, unlike some other examples on this page, where the hero had no idea what their actions would do, ''[[IdiotBall Gwen was warned by time-traveler Paradox not to go through with her plan]]''. True, he didn't actually come right out and say what exactly would happen, but if a near-omnipotent time-traveler who can see multiple timelines and futures, and usually doesn't visit unless something is ''really'' important, tells you not to do something, you should probably listen. Of course, Paradox probably knew Gwen wouldn't listen, but that doesn't give her an excuse.
* In the ''WesternAnimation/BobsBurgers'' episode "The Deepening", we have Bob's plans to stop a ''slowly'' moving animatronic shark from an old movie. He tries a spike strip; the spike strip ends up wrapped around the shark spikes-out. He tries an oil slick; the slick makes it faster. He tries a hook and crane; the weight of the shark pulls the crane onto a power pole, electrifying the shark. {{Lampshade|Hanging}}d by [[SitcomArchNemesis Hugo]] when he states that Bob's only making it stronger, to which Bob yells "he knows he's making it stronger".
* ''WesternAnimation/TheBraveLittleToaster'': After learning that the abandoned house they were left in is now for sale, five appliances head out to reunite with their "master" and go through numerous perils trying to find him. [[spoiler: However, their now-grown up "master" is heading to college, and he returns back to his old home to pick up some of the leftover stuff to use at his dorm (namely, them) roughly about two days after they left. ''They could have avoided all the trouble they went through if they had just listened to Kirby the vacuum cleaner earlier and stayed at the house.'']]
* In ''Disney/BrotherBear'', the central point of the story is that Kenai pursues and kills a bear he blames for his brother's death. Later on, he realizes to his horror [[spoiler:that was Koda's mother]].
* On ''WesternAnimation/ChalkZone'', Rudy causes most of the problems that he needs to fix, whether it be because he left the [=ChalkZone=] portal open, he brought something from the real world into [=ChalkZone=] that causes a problem, or he caused some sort of problem in [=ChalkZone=] itself. Some episodes where this happens include "Gift Adrift" (though Snap made it even worse in that one), "The Wiggies", "Waste Mountain", "[[ChristmasEpisode When Santas Collide]]", ''[[TheMovie The Big Blow Up]]'', "Draw and Let Draw", "Hole in the Wall", and "Power Play", just to name a few.
* ''WesternAnimation/{{Cyberchase}}'': In the very first episode, the kids were squabbling over how to use a library map. This allowed Hacker in {{Cyberspace}} to breach Motherboard's defenses and infect her with a virus that there's practically no way to cure.
* ''WesternAnimation/DangerMouse'': The serial "Day Of The Suds" has Danger Mouse disposing of Baron Greenback's army of renegade washing machines but then gets hounded by a nosy TV reporter for not only disrupting London's need to do their dirty laundry but for the subsequent creation of a giant suds monster caused by the strewn detergent, the sparks from the damaged cables and the fuel used to run the machines during their rampage.
* WesternAnimation/DannyPhantom has been [[UnwittingPawn manipulated]] into doing this a number of times. It usually turns out alright, but the one time it ''didn't'', someone hit the ResetButton.
** Sam also does this once in "Memory Blank".
* In "The Devourer", Zick ended up getting stuck in the Dom-Devourer, a device that is impenetrable. Not only that, for each zap, it saps his powers. By his continuous zap, he loses his ability to see and talk to monsters.
* In the "Hunger" episode of ''WesternAnimation/{{Dilbert}},'' Dilbert genetically engineers a new type of vegetable called the tomeato to solve the problem of world hunger. When he sets up a tomeato farm in Elbonia, the tomeato plants suck all the nutritional value out of the mud, Elbonia's primary resource. When it's discovered that tomeatos are highly explosive, the Elbonians build tomeato-based weapons of mass destruction to bully their neighbors with.
* A fair few times the Urpneys managed to steal ''WesternAnimation/TheDreamstone'' were the result of one of the heroes being careless with it, usually Rufus.
* ''WesternAnimation/DuckTales'': In the "Masked Mallard", Scrooge becomes a vigilante to fight crime, but a crooked TV reporter copies the identity to commit crimes and blame the hero in his reports in order to boost ratings. The real Masked Mallard begins searching all over the city to discover the fake and expose him while clearing his own name. When he finally locates the bogus hero, right before he can swoop in Gizmoduck appears on the scene and arrests the hero, thus not only exposing Scrooge's identity to the public and leaving him a wanted felon but also allowing the real criminal to get away.
** This is partially Scrooge's fault. Gizmoduck's civilian identity is Fenton Crackshell, Scrooge's ''accountant'', and Scrooge is very much aware of this. Yet he never attempted to bring Giz into the loop. (Granted, Fenton is the resident ButtMonkey...)
*** Of course, Fenton likely wouldn't be much help anyway. After catching him, Scrooge reminded him that he was present at the same time as the faux Masked Mallard while he was committing one of his robberies and thus ''couldn't'' be the crook... and Fenton ''still'' couldn't [[TooDumbToLive put two and two together]].
** In the episode "[[Recap/DuckTalesS1E4WhereNoDuckHasGoneBefore Where No Duck Has Gone Before]]", upon discovering that everyone has actually gone up into outer space, Scrooge destroys the computer console in front of him in frustration. Unfortunately, it happens to include the only working radio, keeping him and Gyro from contacting Courage, Launchpad and the boys and warning them about what's happened.
* In the ''WesternAnimation/EdEddNEddy'' episode "Ed Overboard", Marie and Lee kidnap Ed to pacify May, and Edd and Eddy call upon the aid of the Urban Rangers (Rolf, Johnny, and Jimmy), to help them rescue him. While Rolf was distracting the Kankers, Jimmy and Jonny proceed to help Ed down from a tree he's tied to, but [[TheDitz Ed]] offers to distract the Kankers while the Urban Rangers get "help" (ignoring Johnny's protests of "We ''are'' the help!") and proceeds to blow their cover.
* The entire premise of ''WesternAnimation/TheFairlyOddParents'', Timmy Turner never [[BeCarefulWhatYouWishFor being careful for what he wishes for]].
** Crocker's back-story is Timmy's fault as well. [[FreudianExcuse Crocker lost his fairies at ten years old and was attacked by the townspeople because they didn't remember what they were celebrating.]] Timmy tried to prevent it, but it only made things worse.
* ''WesternAnimation/FamilyGuy''
** During the two part episode "Stewie Kills Lois", Brian tells Stewie that he's (in so many words) all talk which basically caused the events of that episode up to and including... Stewie actually going through with his plan to kill Lois, Stewie dumping evidence (since Brian was snooping around) which later led Peter to getting arrested for murder, Cleveland's death, and Stewie's rise to power, before [[OffingTheOffspring being stopped by Peter]]. Jossed the moment after, as it's [[ProsceniumReveal revealed to be one simulation run by Stewie]] of how an actual murder attempt would play out.
** In the episode "Back To The Pilot", Stewie and Brian go back to the first episode via Stewie's time machine to help Brian remember where he lost a tennis ball. Once they return back to the present time, Brian reveals that he told his former self about the September 11 attacks ahead of time, allowing him to stop them from ever happening, much to the chagrin of Stewie, who warned Brian not to alter the past. While watching the local news, it is also discovered that former President George W. Bush, who has lost the 2004 election, has returned to Texas and seceded from the United States, along with the rest of the southern U.S., resulting in a second Civil War. Dismayed, Stewie questions Brian for his actions. Brian insists that things will still be better five years in the future. To make sure, Stewie and Brian then travel to the future, in which the characters appear as a series of three-dimensional objects. They then look at the outside world, only to find utter chaos and destruction. Upon research, Stewie learns that the civil war has led to nuclear attacks all across the eastern United States, resulting in seventeen million deaths (as opposed to the three thousand lives lost in 9/11).
** In "[[Recap/FamilyGuyS9E8NewKidneyInTown New Kidney in Town]]", Peter becomes addicted to Red Bull, annoying, in particular, Lois, who attempts to rectify the situation by disposing of the drink behind his back. Peter then ends up drinking kerosene.
** In "Peter Problems", we see a beached whale with a crowd of worried onlookers around it. Cue Peter, [[BigDamnHeroes who drives into the scene with his new forklift]]. He proceeds to drive the fork into the Whale's side, killing it, and then when he tries to dump the whale back into the sea, he ends up [[BodyHorror disemboweling it thoroughly]].
* In the ''WesternAnimation/FostersHomeForImaginaryFriends'' movie, Frankie [[CooldownHug manages to reason]] with the clingy godlike friend World. And it looks like everything is solved. Until [[UnwittingInstigatorOfDoom Herriman]] [[InterruptedCooldownHug bursts into the room, takes Frankie off, and scolds World]].....Who turns into a TykeBomb. Nice going, Mr H.
-->'''Herriman:''' Good heavens! What's happening?\\
'''Bloo:''' You pissed him off, that's what's happening!
* ''WesternAnimation/{{Futurama}}'': Fry causes it twice.
** In "The Sting", he attempts a HeroicSacrifice to protect Leela from a giant bee but only causes [[spoiler:the bee to sting both of them, pushing the stinger through both his abdomen and hers. His body being in the way lodges the tip of the stinger in Leela's stomach, which injects her with all the venom, and put her into a very deep coma as a result]]. Had he not tried, she would have just had the same injury he had and been patched up the same way.
** Gets everyone in the universe kicked out of the FluffyCloudHeaven in ''The Beast With a Billion Backs'' by disobeying Yivo's decree not to contact the other dimension. [[spoiler:He sends a letter to Bender, who responds by staging a robotic invasion of Yivo]].
* In ''{{WesternAnimation/Gargoyles}}'', the heroes found a woman who had been mutated into a gargoyle-like creature by Doctor Creator/TimCurry, who was working for [[BigBad Xanatos]]. The heroes bust into the lab to rescue her, not knowing that Xanatos had forced Doctor Tim Curry to create an antidote, and he was on the verge of administering it. In the ensuing fight, the vial containing the antidote is smashed, they [[UnwantedRescue drag the mutated woman]] out of a hole in the roof, and throw Doctor Tim Curry into his own vat of electric eels, which means that any knowledge of how to create the antidote dies with him. [[spoiler: Of course, at the end it turns out that Doctor Tim Curry is not dead, and that this was a BatmanGambit, except for a few minor details which [[XanatosGambit Xanatos benefited from]].]]
** [[spoiler:Later Xanatos claims that the 'antidote' was a fake. When the pseudo-gargoyles again try to make Curry create an antidote, it is a completely different color -and there was no reason to trust him that time, either.]]
* In the ''WesternAnimation/GravityFalls'' episode "Dipper and Mabel vs. the Future," [[spoiler:the titular twins' Great Uncle Ford talks Dipper into becoming his apprentice, which would require Dipper to stay in Gravity Falls after the summer is over. His sister Mabel, freaking out already over how terrible everyone older than her says growing up is, tries to freeze Gravity Falls in time forever with [[TimeMaster Blendin Blandin]]'s help so she won't have to grow up and Dipper can't leave her. The only problem is, Blendin was possessed by [[ChaoticEvil Bill]], who used Mabel's desperation to get [[SealedEvilInACan the rift]] and [[{{Cliffhanger}} start]] [[TheEndOfTheWorldAsWeKnowIt the Apocalypse.]]]]
** During Weirdmageddon when the survivors attempt to gather together in a Zodiac in hopes to stop Bill, both Stan and Ford can't stop bickering even in the middle of an apocalypse, the former accusing the latter of their current state and refusing to cooperate for what a petty request of a thank you, while the latter corrects Stan's grammar like a know-it-all which results in them fighting which ended up not only ruining a potential chance of a counterattack but also endanger Dipper and Mabel's life in the process. As a result of this, both the Stan's [[JerkassRealization realize what their grudge leads to]] and decides to finally bury the hatchet to stop Bill.



* In one episode of ''WesternAnimation/TotallySpies'', the girls visit a small town in Italy, only to find it deserted, as a duel between two pizza-wielding brothers has chased everyone else out, after briefly fighting them both, the girls agree to sample each pizza and decide who is the better chef for them. The girls decide they are equally good and advise them to set aside their differences. The brothers tearfully reconcile and agree to work together, the girls happily leave, assuming they mean to set up a joint restaurant. It turns out, they decide to pull a VillainTeamUp and destroy all other pizza chefs. So, yeah...
* In an episode of ''WesternAnimation/ThePowerpuffGirls'', where the three girls and Professor Utonium move to a much larger city than The City of Townsville, which is reversely named the Town of Citysville, The Powerpuff Girls think it's a good idea to continue fighting crime in their new location. After stopping a couple of robbers by destroying the bridge they were trying to get away on, the mayor of Citysville complains to them. "At what point did you think it would be a good idea to blow up the Citysville Bridge? Those robbers stole $4000 in cash. But it's going to cost MILLIONS of dollars to replace the bridge!!!" This catches the girls off guard because, in every single episode prior, [[HeroInsurance plenty of buildings get destroyed Godzilla-style and nobody seems to care a thing about it, as long as the monster is gone.]] Moral: There is a significant difference between destroying a few buildings in the process of preventing a giant monster from razing the entire town, and stopping a pair of petty crooks.
** This is also a major part of the premise of TheMovie, where Mojo tricks the girls into helping him build his volcano observatory and a machine that he claims will "help the town and make it a better place" but actually helps him take over.
--->'''Bubbles:''' This isn't making the town a better place!
--->'''Mojo Jojo:''' Yes, it is... ''[[FalseReassurance for me!]]''
** In "Fallen Arches", a group of elderly super-villains known as the Ministry of Pain come out of retirement, but Blossom refuses to fight them out of a misguided sense of "respecting your elders". This only convinces everyone that the Powerpuffs are afraid of the Ministry's notorious reputation. Blossom then tries to convince [[OldSuperhero the equally-elderly superhero duo of Captain Righteous and Lefty]] to settle their differences and come out of retirement. The episode ends with all the elderly supers hospitalized, and a news reporter talking about "[[CouldHaveAvoidedThisPlot None of this would have happened]] if the Powerpuff Girls had just saved the day!"
** There's also the episode where the girls have a race and go so fast, they warp into a BadFuture where the Him took over because the girls weren't around (due to their race). Ultimately the girls manage to get back to the present, averting such a future from occurring.
** In the episode, "Ice Sore", Blossom tries to stop crooks with her ice breath, but it actually made them get away even faster.
* ''WesternAnimation/TheSimpsons'' has a send-up of the David vs. Goliath legend, in which King David (Bart) fights Goliath II (Nelson) and loses, with Goliath II taking over as king. After some TrainingFromHell, he comes back and does a Nice Job of slaying the giant. The Breaking It part comes when he's told that Goliath II. was the best king the city had ever had, building roads, libraries, and hospitals, and David is arrested for megacide. Whoops!
** Arguably parodied in the episode "[[Recap/TheSimpsonsS8E2YouOnlyMoveTwice You Only Move Twice]]", when Homer takes a job in another city working for [[AxCrazy Hank]] [[AffablyEvil Scorpio]]. Homer turns out to actually be pretty good at his job, successfully setting up the nuclear reactor Scorpio needed for his plan to succeed, and unwittingly preventing Scorpio's plans from being derailed when "Franchise/{{James|Bond}} [[LawyerFriendlyCameo Bont]]" tries to stop him. When the family moves back to Springfield, Scorpio sends Homer a thank-you note, stating that he couldn't have taken control of the East Coast without Homer's help.
** Turned UpToEleven and {{deconstruct|ion}}ed in the movie, where Homer lands Springfield in more trouble than it's ever been, completely pisses off his family, and spends the rest of the film facing the consequences of his actions and trying to fix everything.
*** Although, in his defense, not only does he make it all right again, he also sums up modern heroism surprisingly well:
-->''"Risking my life to save people I hate for reasons I don't quite understand!"''
** Homer subverts this trope in "Boy Scouts N' The Hood" when Bart joins the Junior Campers (an {{Expy}} for [[ScoutOut the Boy Scouts]]) and has to take Homer along on a father-son river rafting trip. They're paired with Ned Flanders and his son, and Homer makes things go FromBadToWorse. Homer loses their map and gets them separated from all the other father-son pairs, and they end up drifting out to sea. They quickly run out of food and water because of Homer's {{Jerkass}} behavior, and he makes their raft spring a leak. However, Homer ultimately saves them when he realizes that there's a Krusty Burger on a nearby offshore oil rig, and his amazing sense of smell leads them to it. They get food and a ride back to Springfield, and Bart congratulates his father. It also turns out that Homer actually did Bart and the Flanderses a ''favour'' by getting them separated from the other rafts. We see what the other father-son teams go through, and it turns out to be a rather unpleasant experience.
*** Played somewhat straight at one point, where it's implied that he stole one of the fathers' swiss army knives, which resulted in him being forced to retreat with the kids after discovering it was gone.
** "Burns, Baby Burns" had Marge telling Homer to go out of the house and tell Mr. Burns about the kidnapping being a hoax along with Burns' son. Her advice only resulted in Homer getting into even more hot water than before when he takes Burns' son out in broad daylight, something that Homer even attempted to warn Marge about why he shouldn't do that immediately.
-->'''Kent Brockman:''' Appearing in broad daylight with police everywhere, ladies and gentlemen, there's only one word for that... idiocy.
-->''*Marge groans embarrassed*''
* ''WesternAnimation/TransformersAnimated'' has a WhackAMole episode in which the wrong Autobot was arrested. Wasp goes on to become insane and vengeful in solitary confinement until he finally breaks out to get revenge on Bumblebee. [[spoiler: Longarm, who's really the Decepticon ''Shockwave'', goes on to become a Prime and the head of Autobot intelligence.]] Well, [[UnusualEuphemism slag]].
** There's also the first SeasonFinale, where Prime decides the [=AllSpark=] key isn't safe with Sari and has Ratchet hold onto it... who then loses it a couple scenes later as he was alone when trying to defend it.
* At the very end of ''WesternAnimation/BeastWars'', Optimus and the Maximals stop Megatron from destroying the Ark and the Autobots on it, preventing a time storm that would destroy the Maximals and made the Predacons dominant. They then tie Megatron to the bottom of the shuttle and bring him back to Cybertron to stand trial. All seems well until Megatron manages to break free from his shackles in a time warp, landing on Cybertron long before the Maximals, becoming a dictator and extracting the sparks of every Cybertronian on the planet, leading to the events in ''WesternAnimation/BeastMachines''.
** From the villainous perspective: according to the Beast Wars: Transmetals game, had Megatron's plan to kill Optimus Prime succeeded, there would have been no Autobot Matrix of Leadership to stop Unicron from destroying Cybertron, dooming both races.
** Silverbolt pulls this off twice in the second season. In "Bad Spark", he unthinkingly detonates the energon crystals on which Protoform X's stasis pod has crashed, heavily damaging himself and his comrades Cheetor and Optimus Primal as well as releasing the monster that would become Rampage -- in fact, it's possible that the energon storm he created might have actually jolted Rampage back to life in the first place. And then, in "The Agenda", he helps Blackarachnia open the blasted-shut tunnel leading to the Ark, thus giving Megatron direct access to the Autobots and Decepticons contained within and giving him the opportunity to attempt his "destroy Optimus Prime to change reality" gambit. LoveMakesYouDumb indeed.
* Occurs twice in the second ''WesternAnimation/{{Teenage Mutant Ninja Turtles|2003}}'' series: first when the turtles "kill" the Shredder in the "Return to New York" which sparks a gang war between different factions trying to [[EvilPowerVacuum fill the power vacuum]]; the second when they steal the Heart of Tengu from The Foot to trade for a cure for the mutated Donatello. Unbeknownst to them, the Heart was the only thing binding a quintet of elemental mystics to the Foot's will; with its theft and subsequent destruction, the mystics were free to resurrect their master, the original (and demonic) Shredder.
** Occurred at least one time in the first ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 TMNT]]'' series involving Donatello's inventions such as when Donatello created a clone of himself to do all the handyman's work. Except his clone doesn't follow orders and a glitch made him stronger and smarter than him. The clone soon worked for the mob boss Pinky [=McFingers=] to create millions of cloned rats to attack the city. It's up for the Turtles to fix this.
*** In the [[WesternAnimation/TeenageMutantNinjaTurtles2012 latest TMNT cartoon]], Karai forms an EnemyMine with the Turtles to stop the Kraang when the Shredder [[RevengeBeforeReason openly refuses to focus on anything but his vendetta against Splinter/Hamato Yoshi]]. However, Leo secretly agrees to let his brothers attempt to take down Shredder in the process, which not only backfires completely, but also leads Karai, who they discover to be [[DaddysLittleVillain Shredder's daughter]] and who had largely been a FriendlyEnemy to them until that point, to declare full-scale war on them in disgust. Leo [[LampshadeHanging even acknowledges that he blew it]].
* In an episode of ''WesternAnimation/SouthPark'', people have been spontaneously combusting. Scientist Randy Marsh discovers that this was caused by people holding in their farts, so he tells people not to hold it in. Unfortunately, the constant release of flatulence begins to cause global warming.
** Speaking of ''South Park''... who knew that Peruvian Pan Flute Bands were the only thing holding back the hordes of Mutant Guinea Creatures intent on destroying the Earth? [[spoiler: The Secretary of Homeland Security]], that's who.
** And who would have known that hybrid vehicles while emitting less smog, they tend to make the people who drive them emit a more obnoxious gas called ''smug''?
** The Imaginationland episodes begin with Cartman and his friends trying to capture a leprechaun (with Kyle agreeing to suck his balls if Cartman proves his claims, as per the BlackComedy nature of the show), but once they capture it, the leprechaun proclaims, "I was sent to warn of a terrorist attack, but you boys have made me late. Now the terrorists will prevail! The end is near!"
** In "Woodland Critter Christmas", Stan is sent by the critters to kill a mountain lion who has been terrorizing them for years. He succeeds in the deed and later finds out she had cubs and would die without her. To make matters worse, the critters are evil and wish to resurrect TheAntichrist, which the mountain lion was trying to prevent. [[spoiler:Then again, this is a story by Cartman.]]
** Sheila in TheMovie when she unwittingly allows Satan and Saddam to rise by killing Terrence and Phillip. Though in [[BigBad her]] case, the term "hero" is used loosely.
* In the ''WesternAnimation/EdEddNEddy'' episode "Ed Overboard", Marie and Lee kidnap Ed to pacify May, and Edd and Eddy call upon the aid of the Urban Rangers (Rolf, Johnny, and Jimmy), to help them rescue him. While Rolf was distracting the Kankers, Jimmy and Jonny proceed to help Ed down from a tree he's tied to, but [[TheDitz Ed]] offers to distract the Kankers while the Urban Rangers get "help" (ignoring Johnny's protests of "We ''are'' the help!") and proceeds to blow their cover.
* ''WesternAnimation/StrokerAndHoop'' pretty much abide by this trope, no sooner then they think they've fixed things. It only proceeds to get worse due to their blundering.
* Used in nearly every ''[[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]]'' episode, and all of the movies. Jimmy's [[InsufferableGenius blinding arrogance]] has even resulted in [[SavingChristmas Christmas nearly getting cancelled]]!



* ''WesternAnimation/DannyPhantom'' has been [[UnwittingPawn manipulated]] into doing this a number of times. It usually turns out alright, but the one time it ''didn't'', someone hit the ResetButton.
** Sam also does this once in "Memory Blank".
* ''WesternAnimation/XavierRenegadeAngel'' is pretty much the poster boy for this trope. As Xavier's attempts to "help" people invariably lead to the deaths of hundreds.
* In the ''WesternAnimation/FostersHomeForImaginaryFriends'' movie, Frankie [[CooldownHug manages to reason]] with the clingy godlike friend World. And it looks like everything is solved. Until [[UnwittingInstigatorOfDoom Herriman]] [[InterruptedCooldownHug bursts into the room, takes Frankie off, and scolds World]].....Who turns into a TykeBomb. Nice going, Mr H.
-->'''Herriman:''' Good heavens! What's happening?\\
'''Bloo:''' You pissed him off, that's what's happening!
* ''WesternAnimation/AvatarTheLastAirbender'', season 2. Politically destabilizing [[GovernmentConspiracy Ba Sing Se]] may have felt right, but it was a very, very, bad idea.
** Then a few episodes later, Katara sees Zuko [[VillainsOutShopping serving tea]] and instantly runs to inform the authorities. If she had investigated further, confronted him herself or thought about the situation for more than a second, Zuko never would have been put in a position to turn to Azula's side to begin with. (And Aang probably would have finished his last chakra.)
** The "Gaang" in general could've seen the Kyoshi Warriors and made sure that it was them. Otherwise, they would've realized that it was [[DressingAsTheEnemy Azula's group instead]] and they wouldn't have learned about the invasion plan.
** In the battle for the Northern Air Temple, the Mechanist deploys a balloon to defeat the attacking Fire Nation forces, but the balloon crashes. The retreating Fire Nation forces take the balloon and are able to mass-produce balloons and zeppelins to augment their military.
* In the ''WesternAnimation/TheLegendOfKorra'' episode ''Beginnings'', Wan sees two massive spirits fighting and threatening to destroy a valley. One begs Wan to help him, while the other tells him to stay out of their conflict.

* In Season 4 of ''WesternAnimation/WinxClub'', [[spoiler:Bloom, Roxy and their friends finally manage to reach the forgotten island of Tir Nan Og, where all of the Earth's fairies are imprisoned, and set them free.]] Yay, awesome! Except that [[spoiler: Morgana, the Queen of the Earth Fairies, has decided that HumansAreTheRealMonsters and that they deserve to be destroyed for ruining the Earth and for not believing in magic any more.

However unknown to our heroines this also frees the spirits of the Tree Ancestral Witches to seek out and team up with their descendants the Trix.]]
* This also happened in ''WesternAnimation/TheRealGhostbusters''. [[spoiler: After being caught in a snowstorm in Christmas Season, the Ghostbusters find themselves in an old-fashioned place, where they see an old man being tormented by 3 ghosts. They charge in and capture the ghosts, apparently saving the old man. Upon returning home, the Ghostbusters find the people around them have become very selfish and that they all hate Christmas. They soon realize that they actually had just went back in time; that the old man was actually THE Ebenezer Scrooge; that the ghosts they captured are THE Ghosts of Christmas Past, Present, and Future; and that they have prevented the events of A Christmas Carol from taking place, leaving an unrepentant Scrooge to provide a different written account, replacing A Christmas Carol, with an opposite message of selfishness to the world.]]
** In "Bustman's Holiday", Ray inherits a castle in Scotland and the Ghostbusters go over to check it out. They stumble upon what the castle's caretaker calls a "keystone ghost" and capture it, but soon more ghosts start popping up. The caretaker reminds them that it was a [[MeaningfulName keystone ghost]], and that [[spoiler:by catching it, they released the other ghosts in the castle. All 360-some of them.]]
* In the [[DirectToVideo Direct To DVD]] film ''[[Franchise/DisneyFairies Tinkerbell]]'', Tink's reckless actions ruin all of the fairies' preparations for spring, threatening to cause a chain reaction that disrupts all the seasons, which would result in an ecological catastrophe. Only her [[GadgeteerGenius brilliant inventions]] get the fairies back on schedule.
* ''WesternAnimation/Ben10AlienForce'' has an example of this in "Time Heals". Gwen successfully goes back in time and prevents Kevin's monstrous mutation ...[[spoiler:only for her to find out that her meddling in time has caused a BadFuture were Hex rules the Earth, Kevin's Charmcaster's slave, Ben's chained in a dungeon as Hex's prisoner, and ''she's dead''.]] It gets worse when you realize that, unlike some other examples on this page, where the hero had no idea what their actions would do, ''[[IdiotBall Gwen was warned by time-traveler Paradox not to go through with her plan]]''. True, he didn't actually come right out and say what exactly would happen, but if a near-omnipotent time-traveler who can see multiple timelines and futures, and usually doesn't visit unless something is ''really'' important, tells you not to do something, you should probably listen. Of course, Paradox probably knew Gwen wouldn't listen, but that doesn't give her an excuse.
* This happens multiple times per season in ''WesternAnimation/XiaolinShowdown''. The biggest screw-ups are caused by Omi in the finales of seasons 2 (used only 1 half of the Yin-Yang Yoyos, causing him to turn evil and join Chase Young) and 3 (froze himself to travel to the future, only to find that Jack Spicer became an EvilOverlord and made it a BadFuture because he wasn't there to help stop Jack).
** The biggest one was arguably when he released the SealedEvilInACan BigBad Hannibal Roy Bean.
** Let's not forget the episode in season 2 when Kimiko breaks the Mosiac Scale, releasing Sibini and resulting in Clay being possessed by him, giving him the chance to possibly get the Monarch Wings, which, when combined with the Mosiac Scale, would give him ultimate power. It's funny because it also literally broke, so it fits into this trope twice as well.
** When the Heart of Jong is recovered by the bad guys, the Master reveals that when the heart combined is with certain Shen Gong Wu, very bad things will happen. End of the world bad. Fortunately, most of the relevant items are in the monks' possession. The Master gives all the Shen Gong Wu to the four kids and tells them to hide; they leave, and when the bad guys question him later, the Master makes it clear he can't say where they've gone because ''he doesn't know''. (This is important.) Raimundo gets it in his head to take some Shen Gong Wu and go help the Master; it turns out ghostly Wuya can read minds, and finds out where the kids are -and the rest of the Shen Gong Wu needed to revive the Mala Mala Jong -an evil powerful warrior.
* This frequently happened in ''WesternAnimation/{{Superfriends}}'', especially during the ''Challenge of the Superfriends'' era with Lex Luthor and the Legion of Doom. A common plotline was for the Legion to con the Justice League into doing their dirty work, [[MacGuffinDeliveryService retrieving]] whatever [[AppliedPhlebotinum phlebotinum]] the plot requires for the villains to threaten the world. In one notable episode, Luthor developed the technology to control solar flares and sent an enormous solar flare to incinerate the Hall of Justice. The Justice League triggered the HOJ's global force-field to prevent the flare from impacting with the Earth. The flare instead bonded with the forcefield, spreading across the upper atmosphere and scorching the Earth, killing all life. A trio of {{Sufficiently Advanced Alien}}s chose to reverse the flow of time to avoid this catastrophe, and then moved the moon to eclipse the sun to block the flare. [[ArtisticLicensePhysics There were no signs of destructive tides as a result, oddly enough]].
* Used as a SecretTestOfCharacter in an episode of ''WesternAnimation/AdventureTime''. After Finn saves a trio of gnomes from a fire pit, they go on a sudden old-lady killing spree, claiming every action of Finn's as justification for the death of additional old ladies. Jake reseals them quickly and delivers a surprisingly straight Aesop (for this show, anyway) to Finn: aside from the fact that the old ladies were fake, the gnomes acting like jerks is in no way evidence that Finn isn't righteous.
** Used again in season 4 Finale. [[spoiler: Finn collects all the crystals of power in Ooo so Billy the Hero can push the Lich into the portal the Enchiridion will open when the crystals are put inside. It turns out the Lich had possessed (and possibly killed) Billy, and the episode ends with Finn and Jake in the mirror world seen in King Worm]] Wonder how they'll fix that!
* Late in ''WesternAnimation/ThunderCats''', Mumm-Ra [[YouHaveFailedMe fails for the last time]], so the Ancient Spirits of Evil banish him to a pocket dimension as punishment. The heroes decide to celebrate by blowing up Mumm-Ra's pyramid. This pisses the Ancient Spirits of Evil off so much that they bring Mumm-Ra back and give him another chance.
* Ron Stoppable, of ''WesternAnimation/KimPossible'', is directly responsible for Señor Senior Sr. becoming a super villain, after pointing out how easy it would be for him to turn his vacation home into an evil fortress.
** Monkey Fist wouldn't have realized "the infant" who beat him earlier was "The Han" he was looking for...especially if Kim hadn't tried to insult his intelligence by mentioning Hana "Han" Stoppable was Ron's sister.
* The entire premise of ''WesternAnimation/TheFairlyOddParents'', Timmy Turner never [[BeCarefulWhatYouWishFor being careful for what he wishes for]].
** Crocker's back-story is Timmy's fault as well. [[FreudianExcuse Crocker lost his fairies at ten years old and was attacked by the townspeople because they didn't remember what they were celebrating.]] Timmy tried to prevent it, but it only made things worse.
* In ''{{WesternAnimation/Gargoyles}}'', the heroes found a woman who had been mutated into a gargoyle-like creature by Doctor Creator/TimCurry, who was working for [[BigBad Xanatos]]. The heroes bust into the lab to rescue her, not knowing that Xanatos had forced Doctor Tim Curry to create an antidote, and he was on the verge of administering it. In the ensuing fight, the vial containing the antidote is smashed, they [[UnwantedRescue drag the mutated woman]] out of a hole in the roof, and throw Doctor Tim Curry into his own vat of electric eels, which means that any knowledge of how to create the antidote dies with him. [[spoiler: Of course, at the end it turns out that Doctor Tim Curry is not dead, and that this was a BatmanGambit, except for a few minor details which [[XanatosGambit Xanatos benefited from]].]]
** [[spoiler:Later Xanatos claims that the 'antidote' was a fake. When the pseudo-gargoyles again try to make Curry create an antidote, it is a completely different color -and there was no reason to trust him that time, either.]]

* At the end of the ''WesternAnimation/TeenTitans'' episode "Trust", Robin gives a communicator to Hot Spot. Except it wasn't Hot Spot but the VoluntaryShapeshifting villain he fought the whole time.

** In the episode "Back To The Pilot", Stewie and Brian go back to the first episode via Stewie's time machine to help Brian remember where he lost a tennis ball. Once they return back to the present time, Brian reveals that he told his former self about the September 11 attacks ahead of time, allowing him to stop them from ever happening, much to the chagrin of Stewie, who warned Brian not to alter the past. While watching the local news, it is also discovered that former President George W. Bush, who has lost the 2004 election, has returned to Texas and seceded from the United States, along with the rest of the southern U.S., resulting in a second Civil War. Dismayed, Stewie questions Brian for his actions. Brian insists that things will still be better five years in the future. To make sure, Stewie and Brian then travel to the future, in which the characters appear as a series of three-dimensional objects. They then look at the outside world, only to find utter chaos and destruction. Upon research, Stewie learns that the civil war has led to nuclear attacks all across the eastern United States, resulting in seventeen million deaths (as opposed to the three thousand lives lost in 9/11).
** In "[[Recap/FamilyGuyS9E8NewKidneyInTown New Kidney in Town]]", Peter becomes addicted to Red Bull, annoying, in particular, Lois, who attempts to rectify the situation by disposing of the drink behind his back. Peter then ends up drinking kerosene.

When he finally locates the bogus hero, right before he can swoop in Gizmoduck appears on the scene and arrests the hero, thus not only exposing Scrooge's identity to the public and leaving him a wanted felon but also allowing the real criminal to get away.
** This is partially Scrooge's fault. Gizmoduck's civilian identity is Fenton Crackshell, Scrooge's ''accountant'', and Scrooge is very much aware of this. Yet he never attempted to bring Giz into the loop. (Granted, Fenton is the resident ButtMonkey...)
*** Of course, Fenton likely wouldn't be much help anyway. After catching him, Scrooge reminded him that he was present at the same time as the faux Masked Mallard while he was committing one of his robberies and thus ''couldn't'' be the crook... and Fenton ''still'' couldn't [[TooDumbToLive put two and two together]].
** In the episode "[[Recap/DuckTalesS1E4WhereNoDuckHasGoneBefore Where No Duck Has Gone Before]]", upon discovering that everyone has actually gone up into outer space, Scrooge destroys the computer console in front of him in frustration.

* The Jetlag Productions version of ''Literature/SleepingBeauty'' adds this twist to the story. After princess Felicity pricks her finger and falls under the evil fairy Odelia's curse, Odelia actually ''thanks'' Primrose, the fairy who altered her death curse, for setting it up. Odelia explains that she just wanted to kill Felicity, but Primrose has made it so that Felicity will remain unchanged for a hundred years, and when she wakes up, everyone she ever knew and loved will have been long dead. Conversely, Felicity's parents are left to moan that they're going to die knowing their daughter will be all alone when she wakes up, as they grow older she won't age a day.

episode "Trust", Robin gives a communicator to Hot Spot. Except it wasn't Hot Spot but where the VoluntaryShapeshifting villain he fought three girls and Professor Utonium move to a much larger city than The City of Townsville, which is reversely named the whole time. Town of Citysville, The Powerpuff Girls think it's a good idea to continue fighting crime in their new location. After stopping a couple of robbers by destroying the bridge they were trying to get away on, the mayor of Citysville complains to them. "At what point did you think it would be a good idea to blow up the Citysville Bridge? Those robbers stole $4000 in cash. But it's going to cost MILLIONS of dollars to replace the bridge!!!" This allowed catches the BrotherhoodOfEvil girls off guard because, in every single episode prior, [[HeroInsurance plenty of buildings get destroyed Godzilla-style and nobody seems to track all care a thing about it, as long as the monster is gone.]] Moral: There is a significant difference between destroying a few buildings in the process of preventing a giant monster from razing the entire town, and stopping a pair of petty crooks.
** This is also a major part
of the Titans' allies. While Robin didn't intentionally give premise of TheMovie, where Mojo tricks the item girls into helping him build his volcano observatory and a machine that he claims will "help the town and make it a better place" but actually helps him take over.

** In "Fallen Arches", a group of elderly super-villains known as the Ministry of Pain come out of retirement, but Blossom refuses to fight them out of a misguided sense of "respecting your elders". This only convinces everyone that the Powerpuffs are afraid of the Ministry's notorious reputation. Blossom then tries to convince [[OldSuperhero the equally-elderly superhero duo of Captain Righteous and Lefty]] to settle their differences and come out of retirement. The episode ends with all the elderly supers hospitalized, and a news reporter talking about "[[CouldHaveAvoidedThisPlot None of this would have happened]] if the Powerpuff Girls had just saved the day!"
** There's also the episode where the girls have a race and go so fast, they warp into a BadFuture where the Him took over because the girls weren't around (due to their race). Ultimately the girls manage to get back

Randy believes it's an act and reminds Mac of the latter's regret. It caused Terra to be pushed off ninja mask with all its cool weapons, powers, and the edge and have a FaceHeelTurn.Nomicon, causing Mac to turn back to his old self while practically exposing himself as the Ninja. Randy also accuses the Nomicon of doing this for not mind-wiping Mac when it fired him as the Ninja.

[[spoiler: Upon returning home, the Ghostbusters find the people around them have become very selfish and that they all hate Christmas. They soon realize that they actually had just went back to the present time, Brian reveals that he told his former self about the September 11 attacks ahead of time, allowing him to stop them from ever happening, much to the chagrin of Stewie, who warned Brian not to alter the past. While watching the local news, it is also discovered that former President George W. Bush, who has lost the 2004 election, has returned to Texas and seceded from the United States, along with the rest of the southern U.S., resulting in a second Civil War. Dismayed, Stewie questions Brian for his actions. Brian insists that things will still be better five years in the future. To make sure, Stewie and Brian then travel to the future, in which the characters appear as a series of three-dimensional objects. They then look at the outside world, only to find utter chaos and destruction. Upon research, Stewie learns time; that the civil war has led to nuclear attacks all across old man was actually THE Ebenezer Scrooge; that the eastern United States, resulting in seventeen million deaths (as opposed to the three thousand lives lost in 9/11).

** Arguably parodied in the episode "[[Recap/TheSimpsonsS8E2YouOnlyMoveTwice You Only Move Twice]]", when Homer takes a job in another city working for [[AxCrazy Hank]] [[AffablyEvil Scorpio]]. Homer turns out to actually be pretty good at his job, successfully setting up the nuclear reactor Scorpio needed for his plan to succeed, and unwittingly preventing Scorpio's plans from being derailed when "Franchise/{{James|Bond}} [[LawyerFriendlyCameo Bont]]" tries to stop him. When the family moves back to Springfield, Scorpio sends Homer a thank-you note, stating that he couldn't have taken control of the East Coast without Homer's help.

they've ever faced who easily takes fixed things. It only proceeds to get worse due to their blundering.
* This frequently happened in ''WesternAnimation/{{Superfriends}}'', especially during the ''Challenge of the Superfriends'' era with Lex Luthor and the Legion of Doom. A common plotline was for the Legion to con the Justice League into doing their dirty work, [[MacGuffinDeliveryService retrieving]] whatever [[AppliedPhlebotinum phlebotinum]] the plot requires for the villains to threaten the world. In one notable episode, Luthor developed the technology to control solar flares and sent an enormous solar flare to incinerate the Hall of Justice. The Justice League triggered the HOJ's global force-field to prevent the flare from impacting with the Earth. The flare instead bonded with the forcefield, spreading across the upper atmosphere and scorching the Earth, killing all life. A trio of {{Sufficiently Advanced Alien}}s chose to reverse the flow of time to avoid this catastrophe, and then moved the moon to eclipse the sun to block the flare. [[ArtisticLicensePhysics There were no signs of destructive tides as a result, oddly enough]].

Except his clone doesn't follow orders and a glitch made him stronger and smarter than him. The clone soon worked for the mob boss Pinky [=McFingers=] to create millions of cloned rats to attack the city. It's up for the Turtles to fix this.
** Occurs twice in the second ''WesternAnimation/{{Teenage Mutant Ninja Turtles|2003}}'' series: first when the turtles "kill" the Shredder in the "Return to New York" which sparks a gang war between different factions trying to [[EvilPowerVacuum fill the power vacuum]]; the second when they steal the Heart of Tengu from The Foot to trade for a cure for the mutated Donatello. Unbeknownst to them, the Heart was the only thing binding a quintet of elemental mystics to the Foot's will; with its theft and subsequent destruction, the mystics were free to resurrect their master, the original (and demonic) Shredder.

* In the ''[[WesternAnimation/TheAdventuresofSuperMarioBros3 The Adventures of Super Mario Bros. 3]]'' episode "Seven Continents for Seven Koopas", the Koopalings take over Earth. What does Mario do to undo these actions? Turn the Great Wall into a dragon, and flood the Louvre.
* On ''WesternAnimation/ChalkZone'', Rudy causes most of the problems that he needs to fix, whether it be because he left the [=ChalkZone=] portal open, he brought something from the real world into [=ChalkZone=] that causes a problem, or he caused some sort of problem in [=ChalkZone=] itself. Some episodes where this happens include "Gift Adrift" (though Snap made it even worse in that one), "The Wiggies", "Waste Mountain", "[[ChristmasEpisode When Santas Collide]]", ''[[TheMovie The Big Blow Up]]'', "Draw and Let Draw", "Hole in the Wall", and "Power Play", just to name a few.
* The premise of ''WesternAnimation/TheAdventuresOfPussInBoots'' involves the hidden city of San Lorenzo, no longer hidden because Puss-In-Boots took a coin out of the treasury. Dulcinea guilts him into staying to protect the city from all the thieves that will now come as he is the reason they need to be defended in the first place.
* In the ''WesternAnimation/GravityFalls'' episode "Dipper and Mabel vs. the Future," [[spoiler:the titular twins' Great Uncle Ford talks Dipper into becoming his apprentice, which would require Dipper to stay in Gravity Falls after the summer is over. His sister Mabel, freaking out already over how terrible everyone older than her says growing up is, tries to freeze Gravity Falls in time forever with [[TimeMaster Blendin Blandin]]'s help so she won't have to grow up and Dipper can't leave her. The only problem is, Blendin was possessed by [[ChaoticEvil Bill]], who used Mabel's desperation to get [[SealedEvilInACan the rift]] and [[{{Cliffhanger}} start]] [[TheEndOfTheWorldAsWeKnowIt the Apocalyse.]]]]
** During Weirdmageddon when the survivors attempt to gather together in a Zodiac in hopes to stop Bill, both Stan and Ford can't stop bickering even in the middle of an apocalypse, the former accusing the latter of their current state and refusing to cooperate for what a petty request of a thank you, while the latter corrects Stan's grammar like a know-it-all which results in them fighting which ended up not only ruining a potential chance of a counterattack but also endanger Dipper and Mabel's life in the process. As a result of this, both the Stan's [[JerkassRealization realize what their grudge leads to]] and decides to finally bury the hatchet to stop Bill.
* In the ''WesternAnimation/BobsBurgers'' episode "The Deepening", we have Bob's plans to stop a ''slowly'' moving animatronic shark from an old movie. He tries a spike strip; the spike strip ends up wrapped around the shark spikes-out. He tries an oil slick; the slick makes it faster. He tries a hook and crane; the weight of the shark pulls the crane onto a power pole, electrifying the shark. {{Lampshade|Hanging}}d by [[SitcomArchNemesis Hugo]] when he states that Bob's only making it stronger, to which Bob yells "he knows he's making it stronger".
* ''WesternAnimation/{{Futurama}}'': Fry causes it twice.
** In "The Sting", he attempts a HeroicSacrifice to protect Leela from a giant bee but only causes [[spoiler:the bee to sting both of them, pushing the stinger through both his abdomen and hers. His body being in the way lodges the tip of the stinger in Leela's stomach, which injects her with all the venom, and put her into a very deep coma as a result]]. Had he not tried, she would have just had the same injury he had and been patched up the same way.
** Gets everyone in the universe kicked out of the FluffyCloudHeaven in ''The Beast With a Billion Backs'' by disobeying Yivo's decree not to contact the other dimension. [[spoiler:He sends a letter to Bender, who responds by staging a robotic invasion of Yivo]].
* More of a Nice Job Breaking It, [[TheDragon Dragon]], but in the ''WesternAnimation/WanderOverYonder'' episode "My Fair Hatey", Commander Peepers' attempt to freeze Lord Dominator's ship instead gives her [[AnIcePerson ice powers]] on top of her [[PlayingWithFire lava powers]].
* Zudo of ''WesternAnimation/TheTelebugs'' only became evil because Grumble the cat interfered during his creation.

to:

* ''WesternAnimation/TheLooneyTunesShow'': In "[=SuperRabbit=]", [=SuperRabbit=] (Bugs Bunny) balls up Lex Luthor (Elmer Fudd)'s power suit one episode of ''WesternAnimation/TotallySpies'', the girls visit a small town in Italy, only to find it deserted, as a duel between two pizza-wielding brothers has chased everyone else out, after briefly fighting them both, the girls agree to sample each pizza and bats decide who is the better chef for them. The girls decide they are equally good and advise them to set aside their differences. The brothers tearfully reconcile and agree to work together, the girls happily leave, assuming they mean to set up a joint restaurant. It turns out, they decide to pull a VillainTeamUp and destroy all other pizza chefs. So, yeah...
* In ''WesternAnimation/TransformersPrime'', Bulkhead's crashing of the Nemesis in an attempt to escape
it inadvertently prompted Megatron to relapse back into outer space. Lex points his [[PsychoSerum Dark Energon]] habit.
* ''WesternAnimation/TransformersAnimated'' has a WhackAMole episode in which the wrong Autobot was arrested. Wasp goes on to become insane and vengeful in solitary confinement until he finally breaks
out that he has just sent an unstable nuclear power source into orbit. Sure enough, to get revenge on Bumblebee. [[spoiler: Longarm, who's really the suit explodes freeing Zod Decepticon ''Shockwave'', goes on to become a Prime and the others from head of Autobot intelligence.]] Well, [[UnusualEuphemism slag]].
** There's also
the Phantom Zone.
* ''WesternAnimation/RandyCunninghamNinthGradeNinja'': "Escape from Detention island" is like one HUGE showing of this trope.
** When Mac Antfee returns, he's a motivational speaker and becomes nice. Randy believes it's an act and reminds Mac of
first SeasonFinale, where Prime decides the ninja mask [=AllSpark=] key isn't safe with all its cool weapons, powers, Sari and has Ratchet hold onto it... who then loses it a couple scenes later as he was alone when trying to defend it.
* At the very end of ''WesternAnimation/BeastWars'', Optimus
and the Nomicon, causing Mac Maximals stop Megatron from destroying the Ark and the Autobots on it, preventing a time storm that would destroy the Maximals and made the Predacons dominant. They then tie Megatron to turn the bottom of the shuttle and bring him back to Cybertron to stand trial. All seems well until Megatron manages to break free from his old self while practically exposing himself as the Ninja. Randy also accuses the Nomicon of doing this for not mind-wiping Mac when it fired him as the Ninja.
** Those pale
shackles in comparison to when Randy and Howard broke into [=McFist=]'s TimeMachine and went back in a time warp, landing on Cybertron long before the Maximals, becoming a dictator and extracting the sparks of every Cybertronian on the planet, leading to the day events in ''WesternAnimation/BeastMachines''.
** From
the original Ninja imprisoned villainous perspective: according to the Sorcerer. They altered the past, freeing the Sorcerer. [[{{Irony}} And McFist wasn't even planning Beast Wars: Transmetals game, had Megatron's plan to use the time machine kill Optimus Prime succeeded, there would have been no Autobot Matrix of Leadership to do anything to harm the Ninja and/or free the Sorcerer]].
* In ''WesternAnimation/BatmanTheBraveAndTheBold'''s AnimatedAdaptation of ''ComicBook/EmperorJoker'', Bat-Mite tries helping out on Batman by giving all his powers to him in the fight against SelfDemonstrating/TheJoker, even though Bat-Mite is warned not to use his powers. However, [[InvisibleMeansUndodgeable he kinda miscalculates on his aim]] and accidentally gives all his powers to Joker, turning him into a {{Reality Warp|er}}ing {{Mad|God}} GodEmperor; and
stop Unicron from that time on everything is going to hell when he recreates the universe in his own image and then starts killing Batman and bringing him BackFromTheDead repeatedly, [[DeathMontage over and over again]].
* On ''WesternAnimation/RegularShow''
destroying Cybertron, dooming both races.
** Silverbolt pulls
this happens on a pretty [[JustForPun regular]] [[OnceAnEpisode basis]]. For instance, off twice in the second episode features Mordecai season. In "Bad Spark", he unthinkingly detonates the energon crystals on which Protoform X's stasis pod has crashed, heavily damaging himself and Rigby desperate to stop a rampaging [[TheMostDangerousVideoGame video game monster]], all because they ignored his comrades Cheetor and Optimus Primal as well as releasing the warning not to active the video game booth.
* In the ''[[WesternAnimation/TheAdventuresofSuperMarioBros3 The Adventures of Super Mario Bros. 3]]'' episode "Seven Continents for Seven Koopas", the Koopalings take over Earth. What does Mario do to undo these actions? Turn the Great Wall into a dragon, and flood the Louvre.
* On ''WesternAnimation/ChalkZone'', Rudy causes most of the problems
monster that he needs to fix, whether it be because he left the [=ChalkZone=] portal open, he brought something from the real world into [=ChalkZone=] would become Rampage -- in fact, it's possible that causes a problem, or he caused some sort of problem in [=ChalkZone=] itself. Some episodes where this happens include "Gift Adrift" (though Snap made it even worse in that one), "The Wiggies", "Waste Mountain", "[[ChristmasEpisode When Santas Collide]]", ''[[TheMovie The Big Blow Up]]'', "Draw and Let Draw", "Hole in the Wall", and "Power Play", just energon storm he created might have actually jolted Rampage back to name a few.
* The premise of ''WesternAnimation/TheAdventuresOfPussInBoots'' involves the hidden city of San Lorenzo, no longer hidden because Puss-In-Boots took a coin out of the treasury. Dulcinea guilts him into staying to protect the city from all the thieves that will now come as he is the reason they need to be defended
life in the first place.
* In the ''WesternAnimation/GravityFalls'' episode "Dipper and Mabel vs. the Future," [[spoiler:the titular twins' Great Uncle Ford talks Dipper into becoming his apprentice, which would require Dipper to stay
place. And then, in Gravity Falls after the summer is over. His sister Mabel, freaking out already over how terrible everyone older than her says growing up is, tries to freeze Gravity Falls in time forever with [[TimeMaster Blendin Blandin]]'s help so she won't have to grow up and Dipper can't leave her. The only problem is, Blendin was possessed by [[ChaoticEvil Bill]], who used Mabel's desperation to get [[SealedEvilInACan the rift]] and [[{{Cliffhanger}} start]] [[TheEndOfTheWorldAsWeKnowIt the Apocalyse.]]]]
** During Weirdmageddon when the survivors attempt to gather together in a Zodiac in hopes to stop Bill, both Stan and Ford can't stop bickering even in the middle of an apocalypse, the former accusing the latter of their current state and refusing to cooperate for what a petty request of a thank you, while the latter corrects Stan's grammar like a know-it-all which results in them fighting which ended up not only ruining a potential chance of a counterattack but also endanger Dipper and Mabel's life in the process. As a result of this, both the Stan's [[JerkassRealization realize what their grudge leads to]] and decides to finally bury the hatchet to stop Bill.
* In the ''WesternAnimation/BobsBurgers'' episode
"The Deepening", we have Bob's plans to stop a ''slowly'' moving animatronic shark from an old movie. He tries a spike strip; Agenda", he helps Blackarachnia open the spike strip ends up wrapped around blasted-shut tunnel leading to the shark spikes-out. He tries an oil slick; Ark, thus giving Megatron direct access to the slick makes it faster. He tries a hook Autobots and crane; Decepticons contained within and giving him the weight of the shark pulls the crane onto a power pole, electrifying the shark. {{Lampshade|Hanging}}d by [[SitcomArchNemesis Hugo]] when he states that Bob's only making it stronger, opportunity to which Bob yells "he knows he's making it stronger".

** Gets everyone in the universe kicked out of the FluffyCloudHeaven in ''The Beast With a Billion Backs'' by disobeying Yivo's decree not to contact the other dimension. [[spoiler:He sends a letter to Bender, who responds by staging a robotic invasion of Yivo]].
* More of a Nice Job Breaking It, [[TheDragon Dragon]], but in the ''WesternAnimation/WanderOverYonder'' episode "My Fair Hatey", Commander Peepers'
attempt to freeze Lord Dominator's ship instead gives her [[AnIcePerson ice powers]] on top of her [[PlayingWithFire lava powers]].
* Zudo of ''WesternAnimation/TheTelebugs'' only became evil because Grumble the cat interfered during
his creation."destroy Optimus Prime to change reality" gambit. LoveMakesYouDumb indeed.


Added DiffLines:

* The title character of ''WesternAnimation/{{Tutenstein}}'' pretty much screws up in every episode.
* More of a Nice Job Breaking It, [[TheDragon Dragon]], but in the ''WesternAnimation/WanderOverYonder'' episode "My Fair Hatey", Commander Peepers' attempt to freeze Lord Dominator's ship instead gives her [[AnIcePerson ice powers]] on top of her [[PlayingWithFire lava powers]].
* ''WesternAnimation/WinxClub''
** In Season 4, [[spoiler:Bloom, Roxy and their friends finally manage to reach the forgotten island of Tir Nan Og, where all of the Earth's fairies are imprisoned, and set them free]]. Yay, awesome! Except that [[spoiler: Morgana, the Queen of the Earth Fairies, has decided that HumansAreTheRealMonsters and that they deserve to be destroyed for ruining the Earth and for not believing in magic any more. And all the other fairies agree with her, and have now declared the Winx girls to be their enemies for not going along]]. Oops.
** At the end of ''[[TheMovie The Secret of the Lost Kingdom]]'', [[spoiler:Bloom and Sky destroy the Obsidian Dimension in order to destroy the spirits of the Three Ancestral Witches and free the King and Queen of Domino (as well as restore said planet to normal). However unknown to our heroines this also frees the spirits of the Tree Ancestral Witches to seek out and team up with their descendants the Trix]].
* ''WesternAnimation/{{Wunschpunsch}}'': In "Nice Wizards", Bubonic and Tyrannia tried to cast a spell to make their supervisor a nice man who wouldn't bother if they did their work or not. Instead of simply allow them to do so, their pets [[WhatAnIdiot interfere with the spell]] and Bubonic and Tyrannia were turned nice instead. The problem with this is that they're so clumsy their attempts to use magic to do good deeds end up causing disaster they're oblivious to. The pets decided to break the spell.
* ''WesternAnimation/XavierRenegadeAngel'' is pretty much the poster boy for this trope. As Xavier's attempts to "help" people invariably lead to the deaths of hundreds.
* This happens multiple times per season in ''WesternAnimation/XiaolinShowdown''. The biggest screw-ups are caused by Omi in the finales of seasons 2 (used only 1 half of the Yin-Yang Yoyos, causing him to turn evil and join Chase Young) and 3 (froze himself to travel to the future, only to find that Jack Spicer became an EvilOverlord and made it a BadFuture because he wasn't there to help stop Jack).
** The biggest one was arguably when he released the SealedEvilInACan BigBad Hannibal Roy Bean.
** The episode in season 2 when Kimiko breaks the Mosiac Scale, releasing Sibini and resulting in Clay being possessed by him, giving him the chance to possibly get the Monarch Wings, which, when combined with the Mosiac Scale, would give him ultimate power. It's funny because it also literally broke, so it fits into this trope twice as well.
** When the Heart of Jong is recovered by the bad guys, the Master reveals that when the heart combined is with certain Shen Gong Wu, very bad things will happen. End of the world bad. Fortunately, most of the relevant items are in the monks' possession. The Master gives all the Shen Gong Wu to the four kids and tells them to hide; they leave, and when the bad guys question him later, the Master makes it clear he can't say where they've gone because ''he doesn't know''. (This is important.) Raimundo gets it in his head to take some Shen Gong Wu and go help the Master; it turns out ghostly Wuya can read minds, and finds out where the kids are -and the rest of the Shen Gong Wu needed to revive the Mala Mala Jong -an evil powerful warrior.
* ''Franchise/XMen''
** In ''WesternAnimation/XMenEvolution'', Magneto destroys a GiantSpider that he thinks is the second key to releasing Apocalypse. Turns out the spider was actually a guardian ''preventing'' Apocalypse from escaping. Destroying it opened the second door. Oops.
** In ''WesternAnimation/WolverineAndTheXMen,'' Wolverine goes and gets himself captured by going in alone. [[spoiler: Trask analyzes his powers, which leads to future beastlike Sentinels with WolverineClaws and a HealingFactor.]] Especially surprising (and satisfying) because otherwise the series takes Wolverine's CanonSue status UpToEleven. ''The only one typically allowed to do anything right'' (except Nightcrawler in his solo episodes) is the one who had a big hand in screwing up the future due to ''his own bullheadedness.''

** In "Woodland Critter Christmas", Stan is sent by the critters to kill a mountain lion who has been terrorizing them for years. He succeeds in the deed and later finds out she had cubs and would die without her. To make matters worse, the critters are evil and wish to resurrect TheAntichrist, which the mountain lion was trying to prevent. Then again, this is a story by Cartman.

** In "Fallen Arches", a group of elderly supervillains known as the Ministry of Pain come out of retirement, but Blossom refuses to fight them out of a misguided sense of "respecting your elders". This only convinces everyone that the Powerpuffs are afraid of the Ministry's notorious reputation. Blossom then tries to convince [[OldSuperhero the equally-elderly superhero duo of Captain Righteous and Lefty]] to settle their differences and come out of retirement. The episode ends with all the elderly supers hospitalized, and a news reporter talking about how the whole farce could have been avoided if only the Powerpuff Girls had done something. Nice going, Blossom!
