** The wizard of the week, Vashtar, goes back in time to kidnap Valerie and bring her to his era. The wizard states on camera he ''knows'' the sorceress Ariel cannot time travel. All he had to do after "finding" Valerie in time was leave Valerie alone.
** Cinda couldn't care less about Vashtar's tyranny -until he invades her domain. Vashtar was trying to kill her and hopefully Maya, with Thundarr's crew as a possible side bonus. All he did was tick off Cinda and set her on his trail.

alone and the prophecy simply couldn't have been fulfilled (unless Ariel somehow found some MacGuffin to allow for time travel, like the Moondial from a previous episode). Worse still, when he ''does'' drag her through time, he doesn't kill her straight away, giving her a chance to escape -- and then he imbues her with superpowers when he accidentally launches a beam of magic through his power-boosting Gem of Glory whilst trying to kill her!

* ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'''s Project Cadmus arc is all about averting a Superhero-Government war that happened in an AlternateUniverse. ComicBook/LexLuthor and ComicBook/{{Brainiac}} take full advantage of the paranoia to trigger one. Even those actions taken by Cadmus without Luthor's overt involvement (Waller claims, and ''believed'' he was mainly a source of income) contributes to the scenario at the end of the arc.

** In the season 2 episode "It's About Time", Twilight Sparkle is unexpectedly visited by Twilight from next Tuesday morning, looking quite disheveled with an eyepatch, burnt mane, bandaged head, and torn black suit. Future Twilight attempts to communicate a message to Present Twilight, but due to the latter's excited questioning about time travel the former only gets to say "Whatever you do, don't-" before she disappears.

Under his orders, Dr. Scratchansniff manages to convince the Warners to keep their lunacy under control so they can attend the banquet... only for Mr. Plotz to force them out of the banquet regardless because he doesn't trust them ''not'' to screw things up. Snubbed and insulted, the Warners return to the banquet and ruin it in their usual KarmicTrickster fashion. In a nutshell, if Mr. Plotz had just let them stay since they were behaving, the entire thing would have gone off without a hitch.

** The "Pandemic" two-parter is full of this. The prophecy - that Craig would be the one to avert the Pandemic - is brought about by a combination of the BigBad sending Craig to Peru, and Craig himself simply walking away when he learns of the prophecy, fully intending to ignore it... leading to him standing on the exact spot necessary to activate his EyeBeams (MakesJustAsMuchSenseInContext) and avert the global crisis.

* ''WesternAnimation/AdventureTime'': "Frost and Fire" plays with the trope; Finn's attempts to find out what the prophecy actually ''is'' are what set it in motion, and by the time he actually gets the message, it's too late to stop it. Finn has a dream involving Flame Princess, the Ice King, and the [[CosmicEntity Cosmic Owl]]. Upon learning that Owl dreams are supposed to be prophetic, he attempts to recreate the circumstances that led to the dream. He's successful, but in the process, sets off a chain of events that results in the Ice Kingdom melted into a puddle and Finn and Flame Princess' relationship in tatters. And what was the Owl trying to tell him?
--> '''Cosmic Owl''': [[NiceJobBreakingItHero You blew it.]]
* The entire plot of ''WesternAnimation/TheAmazingWorldOfGumball'''s "The Oracle" revolves around Gumball hoping to prevent an embarrassing event foretold by Banana Barbara in the form of a painting. Gumball's efforts to prevent the seemingly unlikely circumstances shown in the painting cause all of them to occur, including a shower of raccoons that is a direct result of Gumball sabotaging the family car.
* In ''WesternAnimation/AmericanDad'' episode "Merlot Down Dirty Shame", Stan and Roger became friends in a previous UnInstallment, but after [[KissingUnderTheInfluence Roger kisses Francine while they're both drunk]] he becomes terrified that it'll destroy their newfound friendship. He goes to quite a few extremes to keep Stan from finding out about the kiss -- culminating in him ''[[BuriedAlive burying Francine alive]]'' to keep her from telling, and subsequently burying '''Stan''' alive when he finds out about this -- which naturally pisses Stan off a lot more than a simple AccidentalKiss, and the episode ends with him beating Roger into a bloody pulp and taking away his "best buddies" necklace.
* ''WesternAnimation/{{Amphibia}}'': Leif, one of Andrias' former friends [[spoiler:who was also the Plantar's ancestor]], stole the Music Box that Andrias and his father were going to use to conquer Earth because it gave her a vision of Amphibia being destroyed by [[ColonyDrop its own moon]], and hid it on Earth where it would be used by Anne, Sasha, and Marcy about a thousand years later. However, other parts of the vision are things that we already saw happen, and it's later revealed that the moon falling is caused by [[spoiler:the Core deciding to destroy Amphibia out of anger after Earth is saved from being invaded]], meaning that it could have been prevented if Leif hadn't taken the Music Box to Earth and allowed the girls to come to Amphibia in the first place.
* ''WesternAnimation/{{Animaniacs}}'': In the episode "Taming of the Screwy," Mr. Plotz is holding a banquet for foreign investors, and said investors want to meet all of the workers at the Warner Bros. studio, including Yakko, Wakko, and Dot.

In a nutshell, if Mr. Plotz had just let them stay since they were behaving, the entire thing would have gone off without a hitch.
* The episode "[[Recap/AvatarTheLastAirbenderTheFortuneteller The Fortuneteller]]" from ''WesternAnimation/AvatarTheLastAirbender'' focuses on a town that hangs on to every word of their fortune teller, Aunt Wu. Aunt Wu's predictions are almost always right, but what the villagers don't realize is that it's what they do after hearing her predictions that cause them to happen. Like the old man who was told that he would be wearing red shoes on the day he meets his true love... so he wears red shoes, every day. Wu also predicts that [[SuspiciouslySpecificDenial the village will not be destroyed by the nearby volcano]]. While the villagers' minds are put at ease, the more skeptical protagonists go to check the volcano and find that it is about to erupt. They warn the villagers, who refuse to believe them. So they manipulate one of Wu's fortunetelling methods so she ''will'' predict the eruption, then work with the villagers to divert it. Much to Sokka's frustration, this does nothing to dissuade the village's faith in Wu; after all, she predicted the village wouldn't be destroyed, and it wasn't.
* ''WesternAnimation/BigCityGreens'': In the episode "Hiya Henry", Cricket is irked when Tilly finds Gramma Alice's old ventriloquist dummy, Hiya Henry, to use in her act for Big Coffee's open mic. Cricket spends the whole episode being tormented by Henry, and doesn't tell Tilly or anyone else because he thinks it would hurt her feelings. When Tilly's act begins, he cannot take it anymore and destroys Henry onstage, which in return hurts Tilly's feelings anyway because he ruined her performance without telling her.
* ''WesternAnimation/DannyPhantom'' may have [[MindScrew been this]] if you read TheMovie [[TimeParadox a certain way]]. Specifically, Clockwork was tasked with preventing the BadFuture by [[spoiler: killing Danny]] before it could happen. However, the ghosts he sent back in time failed to do this, causing a series of events that cause it to happen anyway. [[spoiler: Well, almost happen anyway.]]
* ''WesternAnimation/FuggetAboutIt'': In the episode "The Full Mountie." Petey was reluctant to present his new girlfrined to his family since she is Persian and they can be kind of racist to other peoples and she might get offended. When he is finally forced to bring her, he takes any minor comment his family makes as some kind of racist commentary and tries to pre-emptively defend himself, but he brings too much attention to her race, giving the impression that's all he can see and offends her himself, so she breaks up with him.
* A few examples in ''WesternAnimation/{{Gargoyles}}'':
** Demona goes back in time from 1995 to 994 to warn her past self about the slaughter of her clan by the humans. This causes her past self to distrust the humans living in the castle, so she betrays them to the Vikings... who slaughter her clan after taking over the castle.
** Prince (later King) Duncan was paranoid that his cousin Macbeth would try to claim the throne of Scotland, and this paranoia was exacerbated when the Weird Sisters prophesied that Macbeth would become king. So he attacked Macbeth, unsuccessfully, and Macbeth killed him and became king anyway. The catch is that Macbeth had no interest in becoming king and was loyal to Duncan, and he never would have killed Duncan if Duncan hadn't attacked him first.
* In the ''WesternAnimation/HerculesTheAnimatedSeries'' episode "Hercules and the Big Kiss", Cassandra has to kiss Icarus awake. He was put into the sleep in the first place by her efforts to avoid fulfilling a vision which showed her kissing him.
* ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'''s Project Cadmus arc is all about averting a Superhero-Government war that happened in an AlternateUniverse. ComicBook/LexLuthor and ComicBook/{{Brainiac}} take full advantage of the paranoia to trigger one. Even those actions taken by Cadmus without Luthor's overt involvement (Waller claims, and ''believed'' he was mainly a source of income) contributes to the scenario at the end of the arc.
* ''WesternAnimation/TheLoudHouse'':
** In "Raw Deal", the family goes on a trip to Grand Venture State Park, and on the way there, Lucy gives tarot readings. Lincoln's reading is his day at the park will "end in tragedy", which in turn makes him become a hypochondriac and ends up believing everything is dangerous so he won't face anything tragic. As it turns out, there wasn't any danger at the park after all, and he ends up missing out on all the fun which in turn, ends his day in tragedy as predicted.
** In "Stall Monitor", Mrs. Johnson is intent on seeing Rita and Lynn Sr. for Parent-Teacher Conference Night, and Lincoln, worried about what she is going to tell them, tries to stop them from attending with Clyde's help. As it turns out, she was actually telling them what a great student he was, not a bad one, but as a result of trying to stop her, he gets grounded for a week, along with a week of detention.
* ''WesternAnimation/TheSimpsons'':
** One episode regarded a tapestry that predicted everything that would ever happen to it. When one of Homer's ancestors discovered this, he saw that the tapestry depicted him eating it, so he ate it.
** The ''WesternAnimation/TreehouseOfHorror'' segment "The Ned Zone" has Ned gaining the ability to foresee people's deaths. When he foresaw himself shooting Homer to death, he at first successfully changed the fate... only for him to foresee Homer killing everyone via a nuclear explosion at the power plant. Ned then tries to shoot Homer to prevent this, but inadvertently causes the explosion himself anyway.
* ''WesternAnimation/SouthPark'':

The prophecy - that Craig would be the one to avert the Pandemic - is brought about by a combination of the BigBad sending Craig to Peru, and Craig himself simply walking away when he learns of the prophecy, fully intending to ignore it... leading to him standing on the exact spot necessary to activate his EyeBeams (MakesJustAsMuchSenseInContext) and avert the global crisis.
** In the episode "Ike's Wee Wee," Mr. Mackey tries to explain to children DrugsAreBad. But his attempt to educate children by having them smell a sample of marijuana got his fired, mocked, and evicted from his apartment when that sample was stolen. His response to this TraumaCongaLine: ''start taking drugs'' to cope with his depression.
* ''WesternAnimation/SpongeBobSquarePants''
** In "Squid's Visit", [=SpongeBob=] goes to great lengths to get Squidward to visit him, to the point he "borrows" his vaccum cleaner as bait and redesigns his house interior to look like Squidward's, down to the smallest detail. In the end, he gets more than what he barganed for when Squidward has to stay with [=SpongeBob=] when his house gets burnt down from a casserole left in the oven, but [=SpongeBob=] has to sleep outside on the wreckage.
** The episode "[=InSPONGEiac=]" has [=SpongeBob=] slacking off a bit on the job (i.e. using a teensy bit too much mustard) because he went to sleep two minutes later than usual, prompting Mr. Krabs to flip out over it and conclude that he's an insomniac. [=SpongeBob=] starts to get paranoid about his lack of sleep, eventually causing him to become an insomniac for real.
** "The Kwarantined Krab": As it turns out, nobody has the illness and it was all in Mr. Krabs' head, but because everyone was trapped together for such a long time, it causes them to get sick for real, and pretty badly, too.
* ''WesternAnimation/StarWarsTheCloneWars'': An investigation taking place over ten years after Sifo-Dyas' assassination reveals that he really did secretly make the initial order for the clones, lying that the order was under Republic orders after having visions of an upcoming war which which would end in the slaughter of the Jedi. The Sith caught wind of this and killed him, taking over the start of the cloning operations and sealing the fate for the Jedi Order and the Republic, the two groups whose demise Sifo was trying to prevent.
* ''WesternAnimation/TangledTheSeries'' has an interesting take on this in the season 2 finale. From Demanitus' cryptic warning to Eugene about a traitor in their midst, after he decided to bar Rapunzel from entering the castle to protect her, Pascal makes him realize that he was the one who betrayed her by stopping her from fulfilling her destiny. Eugene then tears up the note and tries to find Rapunzel to resume their objective again. [[spoiler: Turns out, this was actually [[SubvertedTrope averted]] as the traitor among them was actually Cassandra, just as Eugene initially thought. ]]
* Inverted in ''WesternAnimation/TeenTitans2003'' season four. Raven is troubled by [[BecauseDestinySaysSo her destiny]] to [[TheEndOfTheWorldAsWeKnowIt destroy the world]] and, along with Slade and [[SatanicArchetype her father Trigon]], repeatedly insists that no matter what she does, there's nothing she can do to prevent it. She fails to realize that the only way the prophecy can come true is if she willingly goes along with it, as the destruction of the world is completely dependent on the conscious actions she makes of her own free will.[[note]]That said, while the prophecy to bring Trigon himself into the world requires her participation, he's still perfectly free to send in a platoon of demons and a certain lieutenant in his stead to force her hand.[[/note]]
* The events of the ''WesternAnimation/TeenageMutantNinjaTurtles2003'' episode "Timing is Everything" implies that the events of the series up to that point are a ''result'' of this. The Utrom Shredder, after his first initial battle with Turtles, travels to the year 2105, where the Turtles and Splinter are currently stuck as a result of a time travel mishap with the time window. He and his army attempt to take the technology, only to start getting their asses kicked all over the place. The initial battle had it take all four turtles ''and'' Splinter in order to defeat the Utrom Shredder; in ''this'' battle, three of the turtles and Splinter trounce his army while Leo beats him down easily, before kicking him back to his own time, but not before Raph reveals that they had defeated him already. This event is implied to be the reason why the Shredder became so ruthless after his first defeat, which would cause the events of the next four seasons, facilitating said defeat.
* ''WesternAnimation/TeenageMutantNinjaTurtles2012'': The four-part [[HalloweenEpisode Monster Arc]] of the fifth season involves Savanti Romero traveling through time and assembling [[MonsterMash an army of monsters]] to take over the world, starting with New York. Renet arrives and takes the Turtles back in time to stop Savanti from doing so, but throughout the arc, their efforts end up only ''helping'' him:
** In "The Curse of Savanti Romero," they go back to Ancient Egypt to prevent him from taking control of a [[{{mummy}} mummified]] [[NephariousPharaoh pharaoh]], but end up not only leading Savanti right to the pharaoh's tomb but activating the mummy's {{curse}}.
** In "The Crypt of Dracula," they go to Transylvania and get assistance from Vulko and Esmeralda, a Gypsy father-and-daughter duo, in stopping Savanti from recruiting {{Dracula}}. In the process, Raph gets bitten by Dracula and [[FaceMonsterTurn turns against his brothers]], and Savanti manages to get control of not only Dracula but Vulko, who's revealed to be a werewolf; before he leaves Transylvania, he even gloats that he's gotten everything he wanted to get and more.
** In "The Frankenstein Experiment," Donnie decides to help Dr. Frankenstein complete [[FrankensteinsMonster his experiment]] with the ulterior motive of collecting synthetic blood to FindTheCure for Raph; all he ends up accomplishing is enabling Savanti to add the monster to his ranks.
** All in all, when they return to New York in "Monsters Among Us!", the group is able to tell right away that their efforts to stop Savanti in the past were AllForNothing; as Leo notes, if anything, the streets are infested with even ''more'' monsters than there were before they left.
* The ''WesternAnimation/ThundarrTheBarbarian'' episode "Prophecy of Peril" deals with three women, the hermit barbarian Cinda, the element queen Maya, and the ordinary human woman Valerie Storm. In the end, the three women destroy the Gem of Glory, the power source of the evil wizard.
--->'''Prophecy Crystal Spirit:'''\\
''One lies beneath Endor with Silver to bind her;''\\
''One comes from the past and her foe will find her;''\\
''One dwells in the Canyon of Death, lonely-hearted;''\\
''Unite them, and Vashtar's power is thwarted!''
** The wizard of the week, Vashtar, goes back in time to kidnap Valerie and bring her to his era. The wizard states on camera he ''knows'' the sorceress Ariel cannot time travel. All he had to do after "finding" Valerie in time was leave Valerie alone.
