History Main / TimeCrash

* The ''{{Futurama}}'' episode with the Vice-Presidential Action Rangers ends with the space-time continuum being shattered by Fry not going to the future.
** Another ''{{Futurama}}'' example: at the end of ''Bender's Big Score'' Bender creates so many time paradox duplicates that he makes a tear in the fabric of reality. This becomes a major plot point in the sequel ''The Beast With A Billion Backs''.

* ZeroHour: [[GreenLantern Hal Jordan/Parallax]] Deliberately triggers one of these destroying the entire timeline with the purpose of rebooting the universe his way. Fortunately, some heroes are pulled outside of normal time to deal with it.

* In ''{{Transformers}}'', this is known as a time storm, and happens whenever someone makes a massive change to history. Cases include the Quintessons bringing Alpha Trion forward in time to cause the original Transformers Rebellion to fail, Megatron killing Cyclonus, and Beast Megatron attempting to destroy Optimus Prime what the latter was in stasis, before the events of TransformersGeneration1.

* In MethodsOfRationality, Harry decides not to experiment with the Time-Turner any more for fear of one of these (after a truly brilliant experiment that, if successful, could have used [[StableTimeLoop Stable Time Loops]] to deduce any information whatsoever, yielded instead the sentence 'DO NOT MESS WITH TIME').

*** Also, the as-yet-unknown (as of late 2010) mastermind behind the cracks in the time field in NuWho season five was trying to cause one of these. We still don't know why.

* In ''{{X-Men The Animated Series}}'', Apocalypse tried to cause one of these so as to rebuild reality as he saw fit once the dust was cleared.

* In the KimPossible movie "A Stitch In Time," it is feared that the destruction of the [[TimeMachine Time Monkey]] will result in a TimeCrash. [[spoiler: It doesn't.]]

* In CJCherryh's MorgaineCycle, it's claimed that any attempt to use the Gates to change the past will result in a catastrophic TimeCrash that will destroy civilization on every world that has a Gate, and there may be millions. The reason Morgaine knows this is that [[AfterTheEnd it's happened before]].

* In the ''BackToTheFuture'' movies, this is a major concern for Doc Brown, although more often than not he'll change the future (or past) for personal reasons. He believes, for instance, that present!Jennifer meeting future!Jennifer could destroy the galaxy. [[spoiler: It doesn't happen.]]

** [[spoiler:Considering how he plans to create a [[TimeParadox massive temporal wedgie]] by destroying the world - and Onion Kid in the process - Chaos may be shooting for a TimeCrash of his own, given the significance of Sarda's attempts to screw the gang over.]]

** Unless you're [[ExactlyWhatItSaysOnTheTin Crazy Joe]], who ''wants'' to destroy the universe [[CorruptCorporateExectutive to draw in more business to his extradimensional restaurant chain]]. If he's in the game when a Time Crash happens, he wins.

* In [[http://memory-alpha.org/en/wiki/Parallels_(episode) one episode]] of ''StarTrekTheNextGeneration'' Worf causes a TimeCrash by flying through a NegativeSpaceWedgie, causing millions of starships ''Enterprise'' from different universes to appear in the same place. Fortunately, he manages to fix it before reality is entirely full of ''Enterprises''. Another [[http://memory-alpha.org/en/wiki/We%27ll_Always_Have_Paris_(episode) episode]] had a MadScientist accidentaly rip open time with his experiments, causing temporal hiccups. Way to DivideByZero there, buddy.

* It's not apparent from the start, but this is the central premise of ''Shrapnel'', an InteractiveFiction by Adam Cadre. [[spoiler: The protagonist and an ill-fated time traveler are caught in a particularly vicious and inescapable TimeCrash caused when the time traveler's time machine was damaged by a piece of shrapnel. Cause and effect cease to exist, and the protagonist experiences several key events in AnachronicOrder and dies multiple violent deaths with no lasting aftereffects before discovering the nightmarish truth.]]

* Parodied in the (as-mentioned-above) "wibbley-wobbley, timey-wimey" DoctorWho universe. In a short made for Children in Need (which WordOfGod says is canon), the Doctor accidentally somehow merges his TARDIS with the TARDIS of [[TheNthDoctor his fifth incarnation]]. Hilarity ensues at first as a starstruck Ten (and a real-life admiring Tennant, who was thrilled to be on the same set with his own childhood favorite Doctor) and a bewildered Five have to stop their inadvertent meeting from ripping a hole in space-time the exact size of Belgium.

** In a less humorous example, Rose causes a TimeCrash in ''Father's Day'' when she saves her father from dying at a predetermined time. [[ClockRoaches Flying Killer Time Monkeys]] [[NiceJobBreakingItHero come out and eat everyone on Earth.]]
