->'''Crow:''' Okay. Two things, Mike... First, uh, well, you blew up another planet, obviously.\\
'''Servo:''' Yep.\\
'''Crow:''' What's that, three for you now?\\
'''Servo:''' Think so. ''(chuckles)''\\
-->-- ''Series/MysteryScienceTheater3000'' [[Series/GeminiMan Riding With Death]], after Mike Nelson accidentally blows up a planet... with a baking soda [[https://www.youtube.com/watch?v=VoDKLscOeuM&t=9m10s bomb]]

Plotting to destroy the planet is a good source of conflict for your standard EvilOverlord, but, when it comes right down to it, destroying the world isn't really a very effective EvilPlan -- especially if it's the world the EvilOverlord is living on: [[WesternAnimation/TheTick it's where he keeps his stuff]]. Basically, plotting to destroy the planet is a good way to demonstrate that you're evil, but there are hardly any situations in which this sort of destruction is going to have any sort of value for the villain.

Once this is understood, you find yourself in the curious situation where the sort of fellow who goes around destroying worlds isn't actively ''evil''. More often, he's more a sort of buffoon. A guy who just doesn't have the sense of responsibility or the ability to wrap his mind around the consequences of his actions to realize that blowing up a planet is a particularly bad idea.

Or, just as likely, ''does it purely by accident''.

[[WhatCouldPossiblyGoWrong He may not even realize his actions could possibly have such ramifications]].

Compare with the OmnicidalManiac, the "serious" version of this trope who ''can'' wrap his head around the concept and wants to do it anyway. If this goes to the next step and the destruction is only really caused by the character's indirect actions, then the character is a DoomMagnet (though the normal version of this also applies as well). Compare FromNobodyToNightmare, when an average person wreaks havoc on purpose after a StartOfDarkness. Compare also with UnwittingInstigatorOfDoom, when someone unintentionally plays a small and/or unlikely but crucial role in some horrible development (usually this action serves as the catalyst).

Not to be confused with WoobieDestroyerOfWorlds, who wants to destroy everything because of past mistreatment. Can be considered a subtrope of NiceJobBreakingItHero.



[[folder:Anime and Manga]]
* ''Anime/{{Memories}}'': Nobuo Tanaka. Hilariously.
* The ''LightNovel/DirtyPair'' have accidentally blown up at least ten planets, though it's only ever an indirect result of their actions.
** Yuri once caused a star to go nova, resulting in a cascade effect across several other stars that would inevitably render an entire sector of space completely uninhabitable. She did this ''intentionally''. In her defense, she had been convinced she was actually undergoing a VR-based test where she was required to act as "unconventional" as possible, with complete freedom to do what she wanted (after years and years of being the proper, uptight, by-the-books member of their team).
* In the ''Anime/SailorMoon'' anime, Sailor Saturn is theoretically capable of destroying the world just by bringing down the tip of her weapon. Thing is: she's a ''heroic character''. So in the anime, she only ever ''starts'' doing this as a threat against certain {{Big Bad}}s but someone always has to stop her. In the [[Manga/SailorMoon manga]], she actually ''does'' destroy the world, just once, at the end of the Death Busters arc. Since this is ''Sailor Moon'' and the main character has "reviving people and/or planets" explicitly as a power, it recovers. The manga also notes that Saturn slumbered during the Silver Millenium until the Talismans carried by Neptune, Uranus, and Pluto awoke her after the Moon Kingdom's destruction, causing her to also destroy the remnants of the Kingdom and allow a new world to be reborn (along with herself and the other Outer Senshi).
* More of a Mike Nelson Destroyer of ''Islands'', but in ''Manga/OnePiece'' [[spoiler: Franky has managed to blow up Dr. Vegapunk's lab and a great portion of the island it was on, destroying countless examples of advanced technology. [[SchmuckBait He did this by pressing a button with a very obvious skull and crossbones sign]]]].
** Spandam with golden den den mushi qualifies too.
* [[TheCollector Jirarudan]] from ''Anime/{{Pokemon 2000}}'' nearly wipes out the world's ecosystem by tampering with some very important, very pretty elemental birds. Destruction isn't part of his plan; only the birds are, and he never comes across as evil, only [[RichInDollarsPoorInSense greedy and blissfully unaware]] of what he kickstarted.
* More of a major territory destroying incident: in Turn 18 of ''Anime/CodeGeass R2'', Suzaku [[spoiler:accidentally nukes the Tokyo settlement with FLEIJA when his Geass command overrides his wish to die in battle. The explosion kills off 30 million people both directly and indirectly, destroys a large portion of the city and completely shatters the Japanese´s trust in Britannia]].
** And played for maximum effect in the big WHAMEpisode of the first season: [[spoiler:Lelouch experiences PowerIncontinence at the worst possible moment during the Special Administrative Zone when conversing with Euphemia, causing her to interpret a geass command to "kill the Japanese", which incites a massacre of said Japanese that is only stopped when Lelouch [[MercyKill tearfully shoots his sister]]]].
* The title character of ''LightNovel/HaruhiSuzumiya'' unconsciously sends off giants to attack an alternate, uninhabited version of Earth whenever she gets too frustrated[[note]]and also unconsciously creates espers to stop them[[/note]] and once unconsciously tried to rewrite the universe.
* This is basically Dewey Novak's plan in ''Anime/EurekaSeven'', but a bit more ambitious. In the show's universe there's a theory that too much thinking by sentient organisms will create what is essentially a thought black hole, and the world covering Coralian life form is dormant to avoid crossing that threshold and destroying the planet. So he tries to wake up the Coralian collective. AllOfThem
* The Great Demon King of ''Manga/{{Beelzebub}}''. Tries to fit destroying the human world into his busy schedule between games of mahjong and poker and singing karaoke or attending demon golf tournaments. His social calendar is so full he ends up sending his ''1-year-old'' spawn to do the deed in his stead.
* A somewhat dramatic version of this trope can be found in ''Anime/PuellaMagiMadokaMagica'' in the form of [[spoiler: [[AliensAreBastards Kyubey/The Incubators]]]]. True, [[spoiler:Kyubey]] was plotting to (indirectly) use [[spoiler: Madoka's witch form]] to destroy the human race, but [[spoiler:its not [[JustForFun/WhyYouShouldDestroyThePlanetEarth for any of the typical reasons aliens do these kinds of things]]]]. Rather than, say, annihilating the human race ForTheEvulz like a typical MagicalGirl villain, [[spoiler:Kyubey's plan is to [[PoweredByAForsakenChild harvest the magical energy generated by Madoka]]]]. The trope comes in when one realizes that [[spoiler:Kyubey [[BlueAndOrangeMorality doesn't understand]] why the human race would rather not be destroyed; after all, since their destruction will extend the lifetime of the universe as a whole, [[EvilCannotComprehendGood they should be eager to be sacrificed]]]].
* In ''Anime/TenchiMuyo'', Washu's way of showing that she is the greatest scientist is by creating a weapon capable of destroying planets as well as weapons capable of destroying ''small galaxies''.
* In ''Anime/SpaceBattleshipYamato'', the crew's attacks push the volcanic activity of [[spoiler: Gamala]] up to a point that the planet explodes. When they arrive at Iscandar, the learn that [[spoiler: the attacks on Earth were the Gamalans' last ditch attempt to establish a new home, as their own planet was dying. The attack merely sped up this destruction]].
* In ''LightNovel/ACertainMagicalIndex'', Touma's father, through arranging trinkets in his house, accidentally summons ArchangelGabriel to Earth via Feng Shui. Touma and his friends have to jump through hoops to stop the angel from destroying the planet and send it back to heaven. Throughout the whole ordeal, Touma's father doesn't notice what is going on.
* In ''LightNovel/DateALive'', when Spirits arrive on Earth, they trigger a spacequake, a SphereOfDestruction that annihilates everything in the surrounding block. When Shido tells Touka about this, she is shocked and remorseful, as she had no idea. Every time she had appeared on Earth, she had assumed she was in a barren wasteland. [[spoiler:There are however, a few Spirits can trigger spacequakes at will.]]
* Many of the planets that ''Anime/SpaceDandy'' visits end up either blown up or made uninhabitable, usually because of him. Sometimes he ends up dying in the process, but thanks to NegativeContinuity, he shows up completely unharmed in the next episode.
* ''Anime/SuperDimensionFortressMacross'' brings us Admiral Bruno J. Global, Destroyer of Canadian Cities. When the ''Macross'' uses a completely untested forcefield while over Ontario, it explodes destroying the entire city. Later on, the crew weaponizes this trait during the destruction of Bodolza's base.
** And this is after destroying Macross City ''twice'' -- once by teleporting the island it was on to the orbit of Pluto, and again by ordering a transformation of the ship while having no understanding of how the reconfiguration would affect the city.

[[folder:Audio Plays]]
* The ''AudioPlay/BigFinishDoctorWho'' story "[[Recap/BigFinishDoctorWho044CreaturesOfBeauty Creatures of Beauty]]", sees [[spoiler:the Doctor]] of all people, and even [[spoiler:the ''Fifth Doctor'', perhaps the most noble incarnation of them all]], getting involved with this. The trigger for the whole plot of the story, happens when [[spoiler:him and Nyssa inside the TARDIS drifts through space, and accidentally collides with what he thinks is just some strange kind of anomaly, but unbeknownst to him it is actually a transport spaceship filled with extremely toxic chemicals, and the crash results in a nearby planet suffering a serious bit of pollution, almost entirely killing off the ecosystem and causing the local population to evolve into a warlike, paranoid race because of the sudden scarcity of resources along with mental degeneration from the poisoning and causing yet another race to commit to a slow-working HeroicSacrifice in an attempt save the population]]. Even worse, the story combines the trope with a ShaggyDogStory. While [[spoiler:the Doctor]] witnesses the destruction and anguish that the aftermath of the event has wrought, he never finds that he was the one who inadvertently caused it all to begin with, and continues on his merry way at the end of the story, completely none the wiser at all.

* Comicbook/{{Galactus}}, the Franchise/MarvelUniverse eater of worlds, is often portrayed as not exactly evil per-se, but as something of a sentient force of nature (though the question of whether it is possible to be a sentient destructive force of nature without this conferring some degree of "evil" may be a form of CarnivoreConfusion). Additionally, he ''was'' just an average Joe astronaut from the previous universe before the Big Crunch forced him into his new job, so he not only never had any choice in the matter--he's become desensitized to it over the eons, and acted the trope much more in the beginning.\\
On the other hand, considering that the alternative to Galactus means [[spoiler:having [[EldritchAbomination Abraxas]] around]], it seems obvious that the universe will happily accept having to deal with Galactus if it means choosing between "systematic destroyer of worlds destroying one every couple of months (Galactus) or a monster that destroys ''everything'' in the same amount of time [[spoiler:(Abraxas)]]". Galactus may end up eating everything, but he keeps it around several billion years more than it would otherwise. That, and Galactus will also start the next Big Bang when the current universe ends, thus giving birth to the new one.
** In the past, it's also been implied that, while his hunger drives him to destroy planets (and all life on them), the shattered remains left behind are freed up to form new planets and new life, staving off entropy -- which means that he functions sort of like a cosmic recycler. This is one of the reasons why Reed Richards has come to the conclusion in the past that, ultimately, the universe NEEDS Galactus. It's assumed that Galactus, being nearly omnipotent, [[ArtisticLicensePhysics can overcome the complications of that plan]].
** Depending on how hungry he is and what type of world his diet is this [[strike: [[DependingOnTheWriter writer]]]] week, he may even have the heralds direct him to planets either not inhabited or not inhabited by sapient life, so he definitely does all he can to minimize suffering when alternatives are available. And if he has to eat an inhabited planet, at least he's nice enough to have his heralds give a planet advanced warning to evacuate before he comes over for dinner. True, it's usually a week or two before the end rather than the decades an evacuation of such scale would take, but it's the thought that counts.
** The one-shot starring Galacta, Galactus' daughter, runs with the more negative interpretation of Galactus. However, since Galacta suffers from daddy issues and is estranged from Galactus, UnreliableNarrator is probably a factor here. The one-shot's ending, with Galactus [[spoiler: saving Galli and her unborn baby]], implies that Galactus is capable of compassion at least.
** A parody of Galactus can be seen in Omnipotus from ''ComicBook/TheTick'' -- a rather dim-witted planet eater who was talked out of destroying the earth and into taking a bite out of the moon instead.
* Franchise/WonderWoman once defeated Ares by simply ensnaring him in her golden lariat, forcing him to see what would happen if he successfully destroyed the world: he'd have no one to worship him or serve him.
* The bounty hunter SelfDemonstrating/{{Lobo}}, of DC fame, has blown up several planets, at least one star system, countless species, and an entire universe. All by accident though (save his own planet; he destroyed it on purpose), owing to nothing but apathy and a habit of leaving high explosive lying around. Not that he wouldn't have blown them all up anyway given the chance...
* A variation of this trope occurs in ''ComicBook/TheAuthority''. A past incarnation of The Doctor is given his old powers back for one hour by the current incarnation to help solve a problem. Past Doctor, of course, being an OmnicidalManiac, doesn't plan to give the power back after an hour, instead he will become the ultimate ruler of everything. [[OutGambitted He is foiled by the plans of the current Doctor]] when, before the hour is up, he is [[spoiler: exposed to the life, love, pain and death of every human who does and has ever existed due to the nature of being The Doctor -- Earth's Shaman, with a spiritual connection to every Doctor who has existed and therefore connected to all life. The ''actual direct exposure'' the pain and destruction he would have caused puts him into shock long enough for the power to revert back to the current Doctor]].
* Comicbook/JeanGrey, impersonated by the Phoenix Force, caused a sun to go nova, in order to feed off the energy. A planet of sentient broccoli-looking people was destroyed in the process. [[Franchise/TheHitchhikersGuideToTheGalaxy This has made a lot of people very angry and has been widely regarded as a bad move.]]
* ComicBook/{{Diabolik}} is this on a small scale: he may be a mass murderer, but he never meant to [[TheDreaded cause mass panic by just having his name mentioned]], or to indirectly cause the plane crash that gave him that fame, or to cause a terrorist attack that, had it been successful, would have started a civil war, or to cause a zombie scare...
* In an out-of-continuity, SuperheroEpisode issue of ''Comicbook/StrangersInParadise'', Freddie Femur is a bumbling villain who purchases a DoomsdayDevice, intending merely to [[TakeOverTheWorld hold the world hostage]] with it. When he trips while carrying it, however, he accidentally sets the device off, destroying the planet and pissing off [[CelestialBureaucracy Saint Peter]] by flooding the gates of {{Heaven}} with several billion souls at once.
* In an Franchise/ArchieComics story, Archie and Jughead find a wand discarded by a stage magician and walk around waving it while speculating out loud about the sorts of amusing mischief one could commit with the wand if it had actual, limitless power to do anything. In doing so, they unwittingly cause such mischief to happen. Then Jughead considers a wand that powerful could fall into the hands of an OmnicidalManiac. Waving it, he says, "He'd say, 'Goodbye, cruel world!', [[KilledMidSentence and--]]." The last panel of the story is a BlankWhiteVoid with no dialogue.
* In ''ComicBook/ZombiesChristmasCarol'', [[spoiler:by spreading the Hungry Death plague through his selfishness and callousness, Scrooge nearly single-handedly destroyed the world and wiped out mankind]].

[[folder:Newspaper Comics]]
* In a very early ComicStrip/{{Dilbert}} strip, he discovered a microscopic inhabited planet, which he accidentally crushed with his microscope while trying to focus in on it. He has accidentally caused quite a few other deaths over the years, but never again on that scale. The best part, as {{lampshade|Hanging}}d by Dogbert in the last panel, is that Dilbert's first words to the tiny planet are "[[IComeInPeace I mean you no harm]]".

[[folder:Films -- Animated]]
* In ''Disney/WreckItRalph'', Ralph's departure from ''Fix-It Felix Jr.'' puts the game at risk of unplugging, which will destroy the world inside. His unintentional introduction of a Cybug from ''Hero's Duty'' into ''Sugar Rush'' threatens to spread a virus throughout their home arcade, which could destroy ''all'' the connected games.
* Disney does this again in ''{{Disney/Frozen}}'', where it turns out to be the cause of the plot—after Elsa runs away to become the Snow Queen, her attempts to flee across the harbor cause the entire fjord to freeze behind her and the temperature of her entire kingdom to plummet. The land enters into an eternal winter, but she doesn't even realize what she's done until her sister comes and asks her to lift her apparent curse. She doesn't know how, which makes things even worse because it causes her EmotionalPowers to start going haywire.
* Scrat in ''WesternAnimation/IceAge'' has a habit of causing natural disasters in his pursuit of acorns. Especially in the short where he caused continental drift. ''WesternAnimation/IceAge5CollisionCourse'' has Scrat accidentally directing an extinction-sized asteroid towards Earth. [[spoiler:Our heroes save the day and deflect the asteroid, only for Scrat to destroy all life on Mars instead.]]


[[folder:Films -- Live-Action]]
* ''Film/SpiesLikeUs'': Austin Millbarge muses after apparently starting WorldWarIII, "And to think my high school guidance counselor said I'd never amount to anything." This sparks a EurekaMoment ("GUIDANCE!? SOURCE PROGRAMMABLE GUIDANCE!") that saves the day.
* ''Film/DarkStar'' featured a starship crew whose job is to traverse the Galaxy, using "Exponential Thermostellar Bombs" to destroy planets that might someday threaten human colonies. For twenty years. On the ragged edge of terminal boredom.
* In Peter Jackson's ''Film/KingKong2005'', Carl Denham's reckless quest to make nature movies and display Kong to the public results in multiple deaths and maimings, chiefly among his friends and associates. This habit persists in the books ''King Kong: The Island Of The Skull'' and ''A Natural History Of Skull Island'', and is {{lampshade|Hanging}}d by another film character, who remarks that Carl has an amazing ability to destroy whatever he loves.
* In ''Film/TheMolePeople,'' the main cast accidentally discover a subterranean civilization descended from the ancient Sumerians and end up destroying them by unintentionally inspiring their ServantRace of mole-men to violently rebel. This is actually a pretty common setup in many "jungle pictures" from the 1940s and 1950s: a group of well-intentioned scientists and explorers stumble upon a LostWorld that's been chugging along on its own just fine before these big dumb white guys showed up, and promptly inadvertently bring out its catastrophic end.
* The TropeNamer Mike Nelson doesn't exactly destroy any worlds in ''Recap/MysteryScienceTheater3000TheMovie''. . . but he does wreck the Hubble Telescope at one point. See Live-Action TV below.
* In the 2005 film version of ''Film/TheHitchhikersGuideToTheGalaxy,'' [[spoiler:Zaphod unwittingly signs the order to destroy the Earth, thinking he was signing an autograph]].
* Canada, in general, in ''Film/CanadianBacon,''. Years earlier, they were sold a device called the Hacker Hellstorm by a U.S. arms manufacturer, R.J. Hacker. Having been told by Hacker it was nothing more than a weather predicting device, they place it on the top of the C.N. Tower in Toronto, where it sits idly until Hacker manages to activate the device himself. In fact, it is a master controller of the entire U.S. nuclear weapon arsenal, and with all weapons still pointed at Russia, global nuclear war is imminent all in part to the Canadians. [[spoiler: Thankfully, the Hellstorm is destroyed--and nuclear war is avoided--by Rea Perlman's character Honey, a laid off Hacker employee who goes postal with a machine-gun after seeing the Hacker emblem on the side of the Hellstorm.]]

* In Creator/KurtVonnegut's ''Literature/CatsCradle'', Dr. Felix Hoenikker invents Ice-9 to help U.S. Marines turn mud into something they can walk on. The world-destroying potential seems never to have occurred to him. Simply, Ice-9 is virtually unmeltable, unbreakable ice thanks to its super-high melting point that lets it remains frozen even at tropical temperatures (although several scenes show folks cooking Ice-9 over a flame to melt it into drinkable water). And it turns all water it touches-into Ice-9. [[spoiler:And then it falls in the ocean.]]
** Ice-9 gets a ShoutOut in ''WebComic/EightBitTheater'', where Red Mage uses it to kill Marilith by stuffing her into a BagOfHolding, then [[http://www.nuklearpower.com/2004/10/28/episode-476-red-mage-in-the-cradle/ casting Ice IX on it and shattering it]].
*** The BagOfHolding is important here, because Ice-9 is not, in ''WebComic/EightBitTheater'', a new arrangement of ice molecules -- it's a magic spell, specifically the highest possible ice spell. If cast (when outside the BagOfHolding, anyway), it would ''remove all heat from the universe''. Fortunately, Red Mage appears to operate on VancianMagic with the really gnarly spells.
** Scientists have created ''actual'' Ice IX -- which is to say a ninth possible arrangement of molecules within the ice crystal -- but it has no special properties, and in fact can't exist outside a narrow band of pressure and temperature (around -200 degrees F).
* In Vonnegut's ''Literature/SlaughterhouseFive'', the Tralfamadorian aliens, who [[UnstuckInTime experience all moments in time simultaneously]], know how the universe will end: in the distant future, a Tralfamadorian pilot will ignite an experimental fuel which, unintentionally on its inventor's part, will cause a lethal cosmic chain reaction.
* In Creator/StephenKing's ''Literature/TheTommyknockers'', the [[InsufficientlyAdvancedAlien Tommies]] themselves have been [[ForScience responsible]] for [[WhatDoesThisButtonDo accidentally]] destroying [[EarthShatteringKaboom whole planets]] during their development stage. Like opening a portal into the heart of a star and flashfrying a planet for example.
* In King's one-minute play, "An Evening at God's," The Almighty is sitting at home in his recliner, drinking a beer and attempting to watch a sitcom on TV. Hanging in front of His face, blocking His view of the TV, is the Earth. Annoyed, He casually reaches out and crushes it, destroying the planet.
* In the French fairy tale "[[http://www.mythfolklore.net/andrewlang/189.htm A Fairy's Blunder]]", the fairy Dindonette manages to drive an entire island's population to extinction because she enchanted the spring so that it would turn children into adults and adults into children. How did it happen? Everyone who drank from the spring would rapidly age and eventually die. Dindonette had intended to please the people of the island rather then seeing them go extinct.
* In Creator/JohnCWright's ''[[Literature/TheGoldenOecumene The Golden Age]]'', in the BackStory, a simulation of the future had resulted in a virtual character burning a planet. The character, shocked, suffered a MyGodWhatHaveIDone, which impelled him to [[InstantAIJustAddWater become an independent, self-aware mind through pondering questions of existence]]. This is an important factor in why people are so opposed to the hero's projects, later on.
* In the Second Foundation Trilogy, written by other authors in the late Creator/IsaacAsimov's Robots and Literature/{{Foundation}} universe, whoever programmed the original Three-Laws Robots is guilty of this. The First Law is "No robot may harm a human, or through inaction, allow a human to come to harm." Because of the definition of 'human', this led to [[spoiler:massive fleets of robot-controlled ships sweeping through the Galaxy, destroying /all/ sapient non-human life, leading to a humans-only Galaxy. The robots removed themselves (mostly), so the humans didn't know what had happened. Essentially we accidentally made a version of Berserkers]].
** That is not canon in the stories written by Asimov; Asimov alludes to that possibility in Foundation and Earth, but it is never established by fact. Asimov himself explored the meaning of 'human' and 'humanity' in a number of stories and novels, which eventually led to the development of the [[spoiler:Zeroth Law]] in ''Robots of Dawn''. His short story "That Thou Art Mindful of Him" suggests that in his view the robots are capable of adjusting their understanding of 'human' to take other sapient creatures into account.
* In ''Literature/StarTrekVanguard'', Scientist tinker with an alien ArtifactOfDoom. They use it to "ping" certain planets to see if there are related installations that could hold all kinds of wonders ([[spoiler: stuff that would later tie into Project Genesis research and replicator tech]]). They stop doing it after they realize that those pings apparently trigger safeguards that cause [[EarthShatteringKaboom Earth Shattering Kabooms]]. The scientists try not to think about how many planets they might have destroyed by accident.
* In ''Literature/JonathanStrangeAndMrNorrell'', Strange has a sort of "habit" of using magic to move entire towns/countries elsewhere. He always means to undo it eventually, but he's inevitably distracted and never does.
* Creator/MichaelSwanwick has a series of stories about a pair of conmen called Darger and Surplus who live in the future after TheSingularity has come and gone. While lovable and not really ill-intentioned (other than the cons), the two have a habit of causing horrible destruction due to meddling with LostTechnology. For instance, the two accidentally burnt down London and destroyed Prague due to unleashing a plague of robotic {{golem}}s.
* ''Literature/DirkGentlysHolisticDetectiveAgency'' tells us the extinction of the dodo was caused by [[spoiler: a time-traveler trying to stop the extinction of ''another'' species]]. The main antagonist is [[spoiler: a TimeAbyss [[NinjaPirateZombieRobot alien ghost]] trying to SetRightWhatOnceWentWrong - his spaceship crashing, which caused the dawn of life on Earth]].
* Used in Creator/LRonHubbard's final two novels, presumably because he wanted his heroes to completely wipe out the bad guys without portraying them as genocidal maniacs.
** ''Literature/BattlefieldEarth'''s hero Jonnie Goodboy Tyler wasn't ''trying'' to completely destroy the Psychlo homeworld, he just wanted to send a nuke through its PortalNetwork to at least prolong the time before the aliens could send reinforcements to their outpost on Earth. But Psychlo "breathe-gas" has a violently explosive reaction to even [[ArtisticLicensePhysics "a single isotope" of radiation,]] and the Psychlos had riddled their home planet with mining tunnels, so that single nuke caused a chain reaction that turned the planet into a radioactive sun. ''Then'' every other planet in the Psychlo Empire, because they don't have a SubspaceAnsible, blindly opened a teleporter link to the capital and got blasted too. The end result is that the (sterilized) prisoners Jonnie takes are the last Psychlos in all the universes, but don't feel bad, [[GuiltFreeExterminationWar they assure him that their race is better off dead.]]
** ''Literature/MissionEarth'''s hero Jettero Heller wasn't ''trying'' to end the Cold War in the most brutal way possible, [[ItMakesJustAsMuchSenseInContext he just wanted to use his space tugboat to tow an icy comet made from Saturn's rings to hit Earth at just the right angle to create a gyroscopic effect to stabilize its spinning core so that the magnetic north pole would stop wandering into the ocean thereby causing the ice cap to melt and the world's water level to rise dangerously high.]] Unfortunately, an enemy fighter pilot (who Heller knew was still around) chose that moment to attack Heller's tug (and Heller didn't abort his run to deal with this threat, but instead asked the enemy pilot to stop trying to kill him), so the tug's controls got damaged, sending the comet straight into the heart of the Soviet Union, annihilating western Russia and killing a hundred million people. [[AndThereWasMuchRejoicing But don't feel bad, everyone can only gush about how this act of destruction only "proves there's a God after all," and how wonderful it is that the Cold War is over.]]
* Belgarion nearly did this in ''Literature/TheMalloreon'' by Creator/DavidEddings while trying to stop two warring Mimbrate nobles. The thunderstorm he called up was fairly small in and of itself and did a wonderful job of making certain he had their undivided attention -- no small feat -- but the timing and location would have started an ''ice age'' if not for the frantic running about by Belgarath and Beldin over the next few months to fix everything. They were ''not'' happy.
* PlayedForDrama in ''Literature/AlasBabylon'', where the nuclear war that wrecks the US and Russia is started by a rookie Air Force pilot who, while trying to shoot down a bogey just outside Syria, misses his target and accidentally blows up an important Syrian port. The author makes a point of highlighting that it was a completely ordinary person's mistake that got out of hand, and not active malice, that precipitated TheEndOfTheWorldAsWeKnowIt.
* It's heavily alluded that previous incarnations of the eponymous [[Literature/TheRifter Rifter]] embodied this trope. According to in-world history, the Rifter is usually an otherwise-ordinary person brought to Basawar from Earth and tortured until their pain and anger spark an apocalypse.

[[folder:Live Action TV]]
* This trope is named for the human lead of ''Series/MysteryScienceTheater3000'', a basically lovable buffoon who, over the course of one season, destroyed three planets, always by accident:
** ''Film/TheDeadlyMantis'' - Mike unwittingly helps [[Franchise/PlanetOfTheApes the simian rulers of future Earth]] repair and detonate an old atomic bomb.
*** Professor Bobo and Doctor Peanut get an honorable mention for helping with said A-Bomb, as well as for Bobo accidentally burning down AncientRome at the end of ''Film/SpaceMutiny'', and Peanut being revealed to have been sent back in time by the Earth's explosion, where he [[BestialityIsDepraved married one of Mike's descendants, which was what caused the apes to take over in]] [[StableTimeLoop the first place.]]
** ''Film/TheSheCreature'' - Mike orders the ''Satellite of Love'''s nanites to help engineer a distraction allowing Pearl and co. to escape the Observers' planet. The little robots decide that MurderIsTheBestSolution and proceed to blow up the planet. This episode also provides the Trope Namer:
--->'''Servo:''' Mike, [[EarthShatteringKaboom you blew up another planet]]! [[WhatTheHellHero What is your deal]]?!
--->'''Mike:''' [[PoorCommunicationKills I just asked them to take care of a little problem!]]
--->'''Crow:''' And they did! Here comes [[TropeNamers Mike, Destroyer of Worlds!]]
--->'''Servo:''' Oh, god of fire and vengeance -- stay away from me!
** ''[[Series/GeminiMan Riding With Death]]'' - Beset by attacking robots, Pearl has the ''[=SoL=]'' provide air support. Mike whips up [[RuleOfFunny a baking soda and vinegar bomb]] to make a "little distraction," but ends up [[RefugeInAudacity overfilling the thing]] after a bad memory leads him to [[TheyCalledMeMad mutter bitterly about past persecutions over similar pranks]].
** ''Film/AgentForHARM'': Mike gets tried for destroying worlds, and is sentenced to death - but his sentence is commuted because he's an amiable lug and instead is remitted to community service aboard the S.O.L.
** For a non-planetary example, while taking a break from watching ''Film/ThisIslandEarth'', Mike takes the helm of the ''[=SoL=]'' and almost ''immediately'' collides with the Hubble Telescope.
--->'''Crow and Servo:''' Mike broke the Hub~ble, Mike broke the Hub~ble!
** Finally, in ''Film/{{Gorgo}}'', Mike destroyed the Nanites' carnival, killing many of them and releasing the deadly protists in their zoo when he dropped a quarter onto their microscopic world in an innocent attempt to purchase a ticket there.
* Stanley Tweedle, the captain of the planet-destroying ship in ''Series/{{Lexx}}'' had a bad habit of overreacting, mostly because, being something of an immature dolt, he never really comes to understand the enormity of blowing up a planet, or that it is not really a proportional response to being mildly annoyed with one of the planet's populace. Several times, he blows up planets entirely by accident. It doesn't help that his ship actually wants to destroy planets (and eat their debris), and often suggests this course of action to Stanley.
-->'''Stanley:''' For example, if I was to say, oh, "Lexx, blow up that planet"...
-->'''Lexx:''' As you command.
-->'''Stanley:''' [[BigNo No!!!]]
** In another episode he threatened the sole inhabitant of a planet by ordering Lexx to blow it up in one minute unless he countermanded the order before then. The inhabitant acquiesced to the threat, so Stanley told Lexx that he was belaying the order... and then, when the one minute mark passed, Lexx blew up the planet anyway. Lexx didn't understand what the word "belay" meant and didn't think to ask.
** In "Eating Pattern," one of the original four-TV-movie cycle, a large alien life form is clinging to Lexx's hull and biting into it. Lexx blows up a nearby planet to produce a cloud of debris so that it can maneuver through it and scrape the offending parasite off. This was an autonomous decision on Lexx's part, not Stanley's, but the motivation was just as petty.
** Xev (the first one) got out of paying a medical bill by destroying a planet behind the space station said medical center was on. Later, at a brothel space station, Stanley does pretty much the same thing, on Xev's advice no less.
* Gaius Baltar, on the rebooted ''Series/{{Battlestar Galactica|2003}}'', didn't actually ''mean'' to give the killer robots unlimited access to the Colonial defense mainframe -- he just thought with the wrong head when confronted by a gorgeous blonde with a vaguely plausible story. (The fact that he then went on to give ''another'' Cylon a nuclear warhead as a courtship gift... and then persuaded the surviving Colonials to settle on a planet that the Cylons promptly conquered... and then acted as a human AppleOfDiscord to destroy Cylon society '''as well'''... well, some guys just don't learn.)
* On ''Series/StargateAtlantis'', Rodney accidentally destroys most of a star system due to his overconfidence in handling some LostTechnology even the {{Precursors}} couldn't handle.
-->'''Rodney:''' It was uninhabited!
** Five-sixths of a star system, to be precise, according to his argument with Weir about it. And ''then'' there was that alternate universe...
* The script for [[Script/OurShowForRingoStarr the never-produced Ringo Starr show]], written by Graham Chapman and Douglas Adams, ends with [[SignificantAnagram Rinog Trars]] unthinkingly waving Ringo goodbye and destroying the universe.
* ''Series/TheKidsInTheHall''. One memorable sketch featured Dave Foley as an alien spy on Earth. After accidentally letting slip that he is an alien, he beams out and orders the planet destroyed. Then, back on the alien planet, he is berated by his superior for blowing up Earth as well as several other planets in the past. The spy then lets slip that he is a double agent, so of course, that planet must be now destroyed.
* Tom Baker's final episode of ''Series/DoctorWho'', "[[Recap/DoctorWhoS18E7Logopolis Logopolis]]" saw the Master "temporarily" halt the workings of the titular planet in order to find out what the inhabitants were up to. It turned out that they'd been holding a deadly field of entropy from doing any damage, and the Master's screwing about with them accidentally unleashes it on the universe. By the time the Doctor manages to stop the entropy field about a ''quarter'' of the universe has been disintegrated, meaning that the Master's single biggest atrocity (if not the biggest by anyone, ever) ended up being caused entirely by accident.
* Oh boy, where to begin with ''Series/KamenRiderDecade''? He's called the "Destroyer of Worlds" and is believed to be a (metaphorical) demon bent on wiping out the multiverse. When our hero Tsukasa is given Decade's powers and tasked with destroying the [[AlternateUniverse Alternate Rider Worlds]] by the originals, he chooses instead to help those worlds' heroes with whatever crisis is going on when he arrives. It seems to work, until the final episode, where [[spoiler:the originals tell him he's actually accelerating the destruction and try to kill him. This leads Tsukasa to FaceHeelTurn and destroy the Riders before committing SuicideByCop. This turns out to be the right thing to do, since it gives the Rider Worlds "immortality" by ensuring that their stories will be told forever, and brings back all the worlds destroyed earlier]].
* ''Series/PowerRangersRPM'' features TheWoobie, Dr. K, trying to escape unjust imprisonment by the government in a secret think-tank. She tries to wipe their computer systems out with a virus she made, but they apprehend her before she can install the firewall. The virus proceeds to escape the area she meant to keep it to, and ''nukes the entire planet'' to desert and rubble.
* The last episode of ''Series/{{Dinosaurs}}'' features Earl Sinclair [[spoiler:accidentally causing the extinction of his species by a chain of events starting with a single wax fruit company being made]].
* End of the first season of ''Series/SledgeHammer''. The army request the aid of the police to fight against a terrorist organization, which has an atomic bomb. They defeat and capture them, but they activate the [[TimeBomb countdown to the atomic explosion]]. They search and find the bomb, and...
-->'''Trunk''': Hammer! You can't defuse that bomb!
-->'''Hammer:''' Trust me. I know what I'm doing. [[spoiler:(''cue mushroom cloud'')]]
* ''Series/{{Outlander}}'' has Prince Charles Edward Stuart (aka Bonnie Prince Charlie) as this. The man is shown as an arrogant drunk convinced it's his divine right to rule Scotland and organizes the Jacobite Uprising. His followers revere him and believe he will lead them to victory and Scottish freedom. Being from the 20th century, Claire knows that not only will the armies be routed easily by the British but the ensuing reprisal attacks will destroy the Highlander culture. Claire is visibly disgusted later when she returns to the 20th century and sees how a museum pushes the idea of Charles as an iconic hero when he did more damage to Scotland than any single man.
* In ''Series/{{Haven}}'', the [[MonsterOfTheWeek Trouble of the Week]] is often completely unaware that they are the one causing the supernatural activity and are often completely unaware of the Troubles themselves.
* ''Series/OnlyFoolsAndHorses'': Uncle Albert's sunk every ship he ever sailed on.
* In the first series of ''Series/{{Blackadder}}'', Percy [[spoiler: accidentally poisons the entire castle except for him and Baldrick, allowing Henry Tudor to take control of the crown and re-write history so that Richard IV's reign never existed]].
** In Blackadder: Back And Forth, Baldrick causes the extinction of the dinosaurs when he dropped his underpants on the ground after killing a T-Rex with the smell alone.
* ''Series/RedDwarf'' started off when Rimmer killed all 1,169 people ([[HumanPopsicle Lister was in stasis at the time]]) on the ship when he improperly fixed a drive plate. Of course, Kryten later pointed out it was Captain Hollister's fault for assigning someone as incompetent as Rimmer to such a task. Interestingly, the AlternateContinuity of the novels dropped this plot point entirely, probably because there was no way they could maintain their ''much'' DarkerAndEdgier tone and still handwave Rimmer not having his personality-disc dumped out an airlock.
** A later episode "Meltdown" had [[TheNeidermeyer Rimmer]] lead an army of [[HistoricalDomainCharacter wax-droids based off of famous historical actors and pacifists against an army of historical tyrants and murderers]], where Rimmer's battle strategy was to [[WeHaveReserves sacrifice almost all of his troops]] as a distraction so Kryten could turn up the planet's heat, killing all of the waxdroids, effectively wiping out the whole planet's population. In the end it turned out it was ''Lister'' who caused Rimmer to act even more irrational than usual when he chewed Rimmer's hologram projector earlier in the episode.
* [[InvertedTrope Inverted]] in ''Series/{{Community}}'' episode "[[Recap/CommunityS2E06Epidemiology Epidemiology]]". Dean Pelton's actions not only helped [[spoiler: stop the ZombieApocalypse from spreading outside of Greendale, but also prevented the possibility of other [[PatientZero patient zeroes]]]].
* On ''Series/StarTrekVoyager'', a species called the Nacene visits the planet Ocampa--and accidentally destroys the biosphere. One of their kind stays behind to care for the Ocampans, becoming known as the "Caretaker."
* Quinn Mallory from Earth-B in ''Series/{{Sliders}}'' caused the destruction of his world by discovering the [[AnotherDimension interdimensional travel]] letting the [[AlwaysChaoticEvil evil Krommag]] discovering it to conquest. This causes him so much guilt that almost drives him insane.
* Almost happens to a General Bradley in the fourth-season finale of ''Series/MadamSecretary''. When the U.S. defense system updates their computers, Bradley, without any authorization, creates a simulation of a massive Russian missile strike on the U.S. But thanks to a snafu, that simulation is run and mistaken for the real thing, leading President Dalton to order a "counterattack." The only thing that prevents that is the general who's meant to input the codes had his security clearance suspended because of a divorce. That delays the launch long enough for Bradley to show up, realize what's happening and abort it seconds before some silos are about to fire off. Needless to say, nearly causing WWIII due to a dumb test leads to Bradley being fired within the hour.

* The Music/LemonDemon song "The Saga of You, Confused Destroyer of Worlds"

[[folder:Tabletop Games]]
* Mister Darke, an archvillain from ''TabletopGame/{{Shadowrun}}'', spent decades working to unleash The Horrors upon Earth. The fact that, when they finally broke loose, their ravenous hordes trampled him into paste may have alerted him that he was playing out this trope all along.

[[folder:Video Games]]
* ''VideoGame/GoldenSunDarkDawn'''s plot is entirely made of this. [[spoiler:The heroes were tricked into activating the Luna Tower, causing the Eclipse and destroying half the population of Weyard just because they were railroaded from a {{Fetch Quest}}, and their only way of breaking through helps activating said tower without their knowledge. The only way to stop it is by activating the Apollo Lens. It turns out that the Eclipse is just another step to the antagonist's plan; the power of the Lens is what Alex and the Tuaparang forces actually sought for; and the former wants to use it on himself for his own benefit.]]
** YouCantFightFate: [[spoiler:This trope must be a curse of Matthew's bloodline, because his father is tricked into destroying the world as well in the [[VideoGame/GoldenSun previous game]].]]
* ''Franchise/{{Metroid}}'' Samus Aran tends to leave the space stations or planets she visits in ruins or [[EarthShatteringKaboom as clouds of debris.]] It's not always her fault - her enemies like to rig their bases to explode if she conquers them - but if Samus shows up in your neighborhood, things are either really bad or about to get worse.
** ''VideoGame/{{Metroid|1}}'': Samus kills the Space Pirates' leader, triggering a self-destruct sequence that blows up their base on Zebes and sparks a feud that spans the entire rest of the series.
*** ''VideoGame/MetroidZeroMission'': In addition to the above, the Space Pirates' mothership blows up after Samus infiltrates it.
** ''VideoGame/MetroidPrime'': Samus kills a monster in a spaceship's reactor, causing the thing to go critical and crash into Tallon IV. The world survives her mission to it, save for [[spoiler:most of a Phazon mine and the Impact Crater]].
** ''VideoGame/MetroidPrimeHunters'': Samus detonates an ancient alien prisoner, inside a spaceship, inside a dimensional rift.
** ''VideoGame/MetroidPrime2Echoes'': Samus manages to destroy a DarkWorld duplicate of Aether, which existed in AnotherDimension. Aether itself was unharmed.
** ''VideoGame/MetroidPrime3Corruption'': Samus converts a section of Elysia's floating city into a nuke and [[ColonyDrop drops it on an obstacle]]. Later she destroys the planet Phaaze, thereby saving the galaxy.
** ''VideoGame/{{Metroid II|ReturnOfSamus}}'': Samus visits [=SR388=], and instead of destroying it simply kills every Metroid living there, with a single exception, which she brings off-world for scientific study.
*** Turns out that by wiping out all the Metroids, Samus removed the planetary ecosystem's top predator, allowing the X Parasites to surge in population and necessitating the events of ''VideoGame/MetroidFusion''.
** ''VideoGame/SuperMetroid'': Samus returns to Zebes, passing through the ruins of the first Space Pirate base she destroyed, and after taking our their new headquarters the resulting self-destruct sequence finally blows up the entire planet.
** ''VideoGame/MetroidOtherM'': The entire game takes place in a spaceship, which, you guessed it, self-destructs at the end. Samus wasn't responsible, for a change.
*** In cutscenes flashbacky and post-gameish, she's spotted on Earth. It's only a matter of time...
** ''VideoGame/MetroidFusion'': A spaceship, made by the same people as the last one, serving the same ''purpose'' as the last one, meets the exact. ''Same. '''End''''', taking [=SR388=], that place that conspicuously didn't blow up in ''Metroid II'', with it. This time Samus was responsible, although she had help.
* ''VideoGame/MakaiKingdom'' has three examples of this, being a mostly comedic game to begin with:
** [[OurDragonsAreDifferent Dragon]] [[DimensionLord Overlord]] Babylon is an extremely powerful and ''extremely'' large overlord... who just so happens to be senile and near-blind. He has a nasty habit of accidentally colliding into various celestial bodies during his wanderings through the cosmos, who usually get away from it worse than he.
** Zetta kicks off the game when he burns a book called the Sacred Tome in a fit of pique (it called him stupid), only to realize too late that [[CosmicKeystone destroying the book will also destroy his entire world]].
** Arguably [[spoiler:Salome]] who, near the end, [[spoiler:smashes her own world into Zetta's newly restored one (just to get his attention)]]. While this is never mentioned again it can't have been a healthy act for either world.
*** She also destroyed Valvoga's netherworld... for no particular reason other than the fact that it was there.
* Although ''VideoGame/SoulNomadAndTheWorldEaters'' is usually prime OmnicidalManiac country, BonusBoss Asagi fits squarely into this trope when she destroys the world ''[[CutscenePowerToTheMax as a pre-battle taunt]]'' without much forethought, just to show off her badassitude. Due to this, you get a NonStandardGameOver even if you win:
-->'''Gig:''' Oh ''please''! You're trying to play the ''victim''? We can't even move on with the story because ''you'' destroyed the world! Now we have to [[NewGamePlus start all over again]]. Seriously, thanks a ''lot''!
* The King of All Cosmos from ''VideoGame/KatamariDamacy'', who took things a few steps further by destroying ''all the stars in the sky'' during a drunken bender.
* ''VideoGame/DrMuto'' starts off with the eponymous MadScientist character presenting what was to be a machine that could provide unlimited clean energy to a planet that is sabotaged and ended up obliterating the planet he lived on, save for a chunk of landmass of his own planet. He then spends the game trying to repair the machine and rebuild the planet. [[spoiler:However, it's later {{subverted}}, as it turns out that [[BigBad Burnital's]] sabotage of Muto's device that blew up the planet, not Muto himself.]]
* Riku sort of accidentally-on-purpose doing this to his own world triggered the plot of ''VideoGame/KingdomHeartsI''. Apparently all he was trying to do was get out and see the universe, and while destroying his world wasn't his intent, calling the darkness forth that did destroy it was a deliberate action so that he could escape his world, which he viewed as a prison.
* True, [[Franchise/SuperMarioBros Bowser]] wanted to [[VideoGame/SuperMarioGalaxy remake the universe in his image and rule over it forever]], but he didn't want to ''destroy'' it. Then Mario comes along, screws up his plans, and causes the formation of a universe-consuming black hole. It was only through the grace of Rosalina and the Star Children that said black hole created a second Big Bang that recreated the universe.
* ''VideoGame/{{Borderlands 2}}'' has [[DumbMuscle Mr. Torgue]], the IdiotSavant[=/=]ManChild who founded the Torgue corporation, who once tried to destroy a planet while him and his shareholders were on it, just because it would look cool. He's genuinely a nice guy and a weapons genius, he's just TooDumbToLive and genuinely doesn't know any better.
* The VillainProtagonist of ''VideoGame/MastermindWorldConquest''. In the end, he does succeed with [[EarthShatteringKaboom Project Genesis]] and leaves the world, but can merely gloat and laugh at a bunch of floating rocks in space from within his one-man shuttle. However, he still seems quite satisfied with the result, and states that it was worth it... except, he forgot his cheesy snacks! [[BigNo NOOOOOOOOOO!]]
* Gehn from the ''VideoGame/{{Myst}}'' series (''VideoGame/{{Riven}}'' and the novels, to be precise) is one of the rare outright villainous examples. He's quite smart and no OmnicidalManiac, but his tendency to destroy worlds makes sense in context because he thinks he can just make more of them. He's convinced that the D'ni were gods [[AGodAmI and believes himself to be the same]]; unfortunately, his myopic insistence on copying existing work in piecemeal fashion means that all of the Ages he writes have, in Atrus' words, "a fatal instability." He believes the Ages he writes are worlds he's created, to do with as he sees fit; as Atrus comes to understand, the Books are gateways to worlds that already exist, and through the complex interplay of word and world, Gehn is not only Linking to worlds, but also changing and destroying them.
* ''VideoGame/{{Touhou}}: Mystic Square'''s plot is kicked off by a demonic invasion, which prompts the Reimu to travel to the magical world of Makai to put a stop to it. At the end of the game she meets Makai's HotAsHell [[AntiAntiChrist goddess]], Shinki, who tries to explain that the demons were merely ''[[GoodAllAlong tourists]]'', but she's still drawn into a fight with the heroine. In the battle that follows, Shinki's attacks reduce the surrounding section of Makai into a flaming ruin... and once she's beaten, Shinki and Reimu [[DidWeJustHaveTeaWithCthulhu sit down for tea]] [[DefeatMeansFriendship and make up.]] Fortunately, Shinki's status as Makai's [[RealityWarper creator]] means that presumably the damage she caused wasn't permanent. Unfortunately, the whole encounter doesn't stop more demon tourists from poking around Gensokyo.
* Played with in ''VideoGame/SandsOfDestruction'', where destruction of the world is the primary goal of the main character and friends and, in fact, the main character is [[spoiler:a construct created to do specifically that]].
* ''The Ring'', a spacestation in ''VideoGame/{{Freelancer}}'', was originally built by the Emperor of Rheinland to be lined with mirrors and to serve Planet New Berlin as a second sun. Somehow, it ended up accidentally turned into an orbital superweapon which vaporised several colonies on the planet's surface.
* Kratos inadvertently causes a number of environmental catastrophes by [[TheProblemWithFightingDeath killing the gods]] in ''VideoGame/GodOfWarIII''. For example, killing Poseidon, god of the ocean, causes a flood which decimates Greece. Alternatively, he knows exactly what would happen, but simply doesn't care.
* In ''VideoGame/{{Fallout 3}}'''s DLC Mothership Zeta, while exploring the eponymous spaceship, you will come across [[SchmuckBait a button]]. When pressed, [[spoiler: the ship's [[KillSat giant beam weapon]] blasts a giant crater into Canada, visible from space through the large windows inside the room]]. Think of all the tribes, civilizations and potential nation states you just destroyed. YouBastard.
* The ''VideoGame/FalloutNewVegas: Lonesome Road'' expansion reveals this to be the backstory of the [[PlayerCharacter Courier]]. [[spoiler:The Courier was once responsible for helping the towns of Hopeville and Ashton develop into thriving communities. However, a package s/he delivered from Navarro ended up triggering the dormant nukes hidden in the bunkers beneath the town, turning the Divide into a devastated hellhole that makes the rest of the wastelands look like paradise. Worse, the act gives [[{{Foil}} Ulysses]], then a Frumentarius of Caesar's Legion, some ideas about how one person can change the fate of a nation...]]
* In ''VideoGame/{{Fallout 4}}'''s DLC Automatron, the idea is played with, though the outcome is sadly played straight.[[spoiler:[[BigBad The Mechanist]] sought to bring forward peace and stability through a robotic police force. The hope was that the robots would protect traders and caravans on the road from the various horrors of the Commonwealth Wasteland. However, the Mechanist made a bit of a mistake using [[FateWorseThanDeath Robobrains]] as the field commanders of the robot forces. As it turns out, said Robobrains in question wound up becoming corrupted after 210 years of inaction. So they interpreted "protect the people" as [[KillEmAll "kill everyone we see"]]. In their minds, the Robobrains saw that [[EpicFail if everyone was dead,]] [[NiceJobBreakingItHero they were "saved"]]. If the Mechanist can be convinced to see where everything went wrong, [[MyGodWhatHaveIDone it becomes clear that this was never the intention]].]]
* The title character of ''VideoGame/{{NieR}}'' just wants to save his daughter/sister. Through a series of misunderstandings and mistakes, this has the ultimate result of [[spoiler: dooming humanity to extinction]].
* In ''VideoGame/StarOceanTheLastHope'', [[spoiler:[[TheHero Edge]] incidentally causes the [[EarthShatteringKaboom utter annihilation]] of an alternate universe Earth after [[WhatAnIdiot giving an object from the future to a clearly crazy female scientist]], who then proceeds to use it in an experiment that [[GoneHorriblyWrong goes badly]]. He [[HeroicBSOD doesn't]] [[MyGodWhatHaveIDone take it well]]]].
* Possible in ''VideoGame/StarRuler''. Some time in, you will be building and facing ships more durable than planets and with the firepower needed to destroy each other. This can easily mean that you target a planet to cleanse it of enemy life and end up accidentally fragging it because you underestimated just how just firepower you have in play. Beyond tech level 40, it's possible to accidentally [[StarKilling blow up stars]] by selecting the wrong target. Better hope the [[OmnicidalManiac other players]] don't "''accidentally''" target the quasar at the center of the galaxy and [[ApocalypseHow destroy all life in the galaxy in a hellish expanding wave of radiation]].
* In ''VideoGame/RadiantHistoria'', there are quite a few ways to accidentally doom the world to slowly turning into sand (usually a result of a few major characters getting offed) as a direct result of your decisions. A few instances in particular REALLY lean towards this trope, however-- such as not resolving a RomanticSidequest between two relatively minor characters, resulting in the death of one of them, which is then pinned on the surviving character's people and sparks an all-out war between their respective countries. Or not taking the first watch on a night shift, causing a fatal misunderstanding when an ally arrives at your camp and sees a major character who is your ally but is also on the other side of the war, resulting in both characters (plus the character who takes the night watch in your place) killing each other. Or [[ScrewThisImOuttaHere retiring from the war to be with your Love Interest]] (though this one is more TooDumbToLive than anything).
* ''VideoGame/EverquestII'' finds the Quel'ule Erudites managing to [[spoiler: blow Luclin to tiny pieces]] in an attempt to reactivate the Ulteran Spire network, and [[spoiler: removing their own homeland to Ultera]] as a bonus.
* In the custom ''VideoGame/CityOfHeroes'' mission "Save the World in Five Minutes", one [[MorallyAmbiguousDoctorate Dr. Armageddon]] is about to contaminate the atmosphere with plutonium and destroy all intelligent life in order to become immortal. Metaphorically, of course.
* In ''VideoGame/MasterOfOrion 3'', the stellar converter is a late game weapon that can destroy planets (not stars, despite the name). If you forget you have one somewhere in your fleet when attacking a planet, it's very easy to accidentally blow it up. The AI suffers a similar problem since it always bombards planets if it has the chance, making it incapable of capturing them late in the game no matter how many invasion troops it tries to send (although this won't be noticed in the vanilla game since a fan-made patch is required to get it to use troops properly in the first place). The previous games in the series avoided this problem by requiring a deliberate effort to use stellar converters, and also allowed you to build planets out of the residual asteroid belts if you later decided you'd made a mistake.
* According to the lore of ''VideoGame/FlightRising'', the Arcanist counts as one of these - he's the youngest of the game's dragon gods, created from a magical explosion that doomed humanity and born into an abandoned world. So he set up shop in an abandoned observatory, and flew about the universe for a time seeing everything there was to see. And ''then'', out of curiosity and a desire to find a friend, he started talking to [[EldritchAbomination The]] [[BigBad Shade]], [[NiceJobBreakingItHero letting it know where the nearest world to leach of its power was.]] The repercussions of that are still ongoing.
* ''VideoGame/SpecOpsTheLine'''s protagonist Captain Walker just wants to help out, and even though his recon team is supposed to simply check for any survivors in the sand-choked ruins of Dubai and then call for reinforcements to properly evacuate the city, Walker insists on getting involved in a civil war involving Colonel Konrad's rogue soldiers and the civilians they tried and failed to evacuate six months earlier. Which leads to Walker killing other US soldiers in self-defense over a miscommunication. And making enemies out of the entire "Damned 33rd" Infantry Battalion. And getting involved with a CIA team with less-than-heroic intentions for the city. [[spoiler:And using white phosphorus mortar rounds to destroy a refugee camp he thought was an enemy stronghold. And accidentally destroying Dubai's water supply, dooming thousands of people to a slow and painful death. And destroying a communications tower vital for any evacuation attempt. And potentially massacring another refugee camp after they lynch one of his men. And all but wiping out the entire Damned 33rd. At the end of all the carnage and madness, Walker finally realizes that ''he'' [[HeelRealization is the true villain of the story,]] which can potentially see him DrivenToSuicide.]]
-->'''[[BigBad Colonel Konrad:]]''' There were over five thousand people alive in this city, the day before you arrived. [[WhatTheHellHero How many are alive today, I wonder? How many will be alive tomorrow?]] I thought my duty was to protect this city from the storm. I was wrong. [[WellIntentionedExtremist I have to protect it from]] ''[[DestructiveSavior you]]''.
* This trope is at the core of the ''Franchise/MassEffect'' series. [[spoiler: Many millions (if not billions) of years ago, a race of giant, squid-like creatures later called Leviathans used their powerful psionic powers to enthrall other species. With this ability, they were able to become the apex lifeforms of the galaxy, using their "thralls" to pay them "tribute" while keeping a hands-off approach to ruling the galaxy. However, they noticed that species had a tendency to create synthetic life which then [[RobotWar inevitably turned on them]], which naturally made getting tribute a touch problematic. The Leviathans then made their own artificial intelligence and gave it the mandate of "preserve life at all costs". Only later did they realize that after exhausting all other options, their intelligence had resorted to creating bio-mechanical monstrosities that began harvesting the biological material of all sentient life in the galaxy, [[ExactWords "preserving" all life "at any cost".]] Eventually, the machines, later known as "Reapers", attacked and almost wiped out the Leviathans, before retreating into the dark space outside the galaxy. They waited for a few thousand years, came back and did it again. This cycle of harvesting continues for many more eons, and is about to happen again just as humanity is taking to the stars.]]

* Red Bright from ''Webcomic/ColourWheel'': [[http://colourwheelcomic.com/comic/page-8/ "You know how the city's name is 'New Chroma'? He's what happened to the old one."]]
* A pseudo-example: in ''Webcomic/{{Goats}}'', computer programmer Phil uses completely random trial and error to try and fix a terminal flaw in the source code of the entire universe. He is casual about the process until he is informed that the simulations he is running involve the creation and destruction of sub-universes, and the amount of living creatures he wipes out with each universe destruction works out to "3.5 gigaHitlers".
** Which works out to between 21 to 70 'quadrillion' (21*10^15 - 70*10^15), depending on which numbers you use.
* In ''Webcomic/FlintlockesGuideToAzeroth'', Flintlocke attempts to find a device called the Ultimate Goblin-Engineered Weapon. On one occasion, when asked what he intends to do with said device, he yells out "We're gonna save and/or destroy tha world!" This is a particularly interesting example because Flintlocke is not evil per se, although he has incredibly poor judgment when it comes to explosives.
* ''Webcomic/TheWotch'' [[LampshadeHanging hangs a lampshade]] on this trope in [[http://www.thewotch.com/?comic=something-wicked-30 this strip]].
* Similarly, in ''Webcomic/TheOrderOfTheStick'', when Roy accuses Xykon of plotting to destroy the world, Xykon replies, "Hey, I LIKE the world. Some of my best evilness took place here." The gods alone know what he'll do if he ever figures out [[spoiler:what [[DragonWithAnAgenda Redcloak]]'s really up to..]].
** Xykon says he won't destroy the world unless he's really really bored. ''Half of the time we see him in the comic, he is bored.''
** The eponymous Order of the Stick and their allies may count as well; the plot of the comic revolves around five Gates; the existence of these Gates is key to the safety of the multiverse. The Good Guys have so far destroyed [[spoiler: three out of the five so far: once on accident (due to the QuirkyBard activating a self-destruct rune), once due to a misunderstanding (a long story, boiling down to "She thought it was a good idea at the time"), and once on purpose (because, due to Plot, it was safer to destroy that Gate rather than let it fall into the bad guys' hands)]]. Given that one Gate was accidentally destroyed by the Bad Guys in the backstory, things are starting to look a ''little'' hairy.
* In ''Webcomic/AMiracleOfScience'' a [[ScienceRelatedMemeticDisorder mad scientist]] fails due to the fact that "destroying the world you want to conquer" doesn't exactly count as a credible threat.
* Despite occasionally saving the world as well, the cast of ''Webcomic/SluggyFreelance'' (particularly Riff) do this from time to time. At one point (albeit in non-canon filler), Riff builds a machine that lets the gang view versions of themselves [[AlternateReality from alternate realities]]. A surprising number of these parallel universes involve one of the main characters [[http://www.sluggy.com/daily.php?date=031110 causing Armageddon]].

* WebComic/{{minus}} has the power to alter reality in any way she pleases, frequently leading to mass destruction and catastrophe because she doesn't really comprehend the consequences of her actions. At one point, she unintentionally killed everything on Earth (except Larry) by bringing back to life everything that had ever died.
* In ''Webcomic/{{Homestuck}}'', Karkat is charged with the creation of our universe (the one you're in right now), but he's in too much of a hurry to beat the game and doesn't find the last required component. As a result, it becomes unstable and [[spoiler:is eventually destroyed by a kind of in-universe cancer]]. While Karkat's negligence was by far not the only factor in this outcome, and waiting longer to beat the Black King may have been untenable (because Sburb gets harder to beat the longer it goes on) it definitely didn't help an already bad situation.
* In ''Webcomic/CommanderKitty'', ''Nin Wah'' of all people ends up setting back the party for several pages [[spoiler: [[http://www.commanderkitty.com/2012/08/15/nin-wahs-agenda/ with one thoughtless act of sabotage against an undeserving CK]] which [[http://www.commanderkitty.com/2012/09/09/she-dun-goofed/ ends up killing the friendly "Safe Mode" Zenith, leaving the space station they're on crippled]], [[http://www.commanderkitty.com/2015/03/15/so-much-for-that-plan/ and giving Zenith's original villainous personality an opportunity to regain control]].]]
* In ''Webcomic/GirlGenius'', dangerous Sparks (i.e. most of them) can be divided into two groups: The evil ones whose creations wreak havoc on purpose, and the well-intentioned ones whose creations wreak havoc by accident. The backstory for the comic includes references to incidents such as a Spark who tried to make a land bridge across the English Channel and ended up sinking most of Britain and a Spark who loved molasses and didn't want to run out, so he made a fountain that dispensed it in infinite quantities, drowning his hometown in treacle.

* Bill from ''LetsPlay/TwitchPlaysPokemon'' is a more intelligent example, [[ButForMeItWasTuesday but he’s just as uncaring.]] [[WhiteCollarWorker Yes,]] [[VideoGame/PokemonRedAndBlue that]] [[AdaptationalBadass Bill.]] ''Twitch Plays Pokemon'' is essentially tens of thousands of people controlling a single avatar named Red, one button command at a time. [[FightingFromTheInside The players tend to disagree A LOT]] [[MissionControlIsOffItsMeds on what Red should do,]] and in result, Red can’t even walk in a straight line. Enter Bill’s PC, the one and only device that stores your Pokémon... [[AnyoneCanDie and has the option to release them into the wild.]] [[KilledOffForReal Forever.]] [[HoistByHisOwnPetard And in Red’s case, accidentally.]] [[HeroKiller The PC itself]] quickly became [[TheDreaded the most notorious and feared]] [[ArtifactOfDoom object]] [[AIIsACrapshoot in the entire game,]] especially after the [[DarkestHour twelve-Pokémon massacre]] known as “Bloody Sunday.” [[HateSink Yet, the existence of Bill was not forgotten,]] spiraling him into '''major''' AdaptationalVillainy.
* Without even realizing it, Rusty in ''WebAnimation/PokemonRusty'' caused a massive wildfire on Route 17, [[spoiler:trained a Beedrill to be a cruel hate-filled boss of Team Rocket and caused a demigod Bidoof to enslave humanity.]]
* In "Breaking Wind", [[WebAnimation/HappyTreeFriends Splendid]] inadvertently destroys the world..... by farting.
* BigBad Zorc Necrophage is portrayed in this manner in ''WebVideo/YuGiOhTheAbridgedSeries''. Oh, sure, he's constantly ''[[CatchPhrase destroying the world]]'', but he's also the lovably goofy protagonist of his own sitcom called "Zorc and Pals". Not to mention that we never actually see him destroying anything.
** Also, in the ''Abridged Movie'', Yami lampshades this by questioning Anubis, the movie's BigBad, about why he wants to destroy the world.
-->'''Anubis''': ...And then I'll destroy the world.
-->'''Yami''': [[AndThenWhat Why would you want to do that]]? What's the point of destroying the world? What do you gain from that?
-->'''Anubis''': I... Don't understand the question.
-->'''Yami''': Look, you must have a reason for wanting to destroy the world. Otherwise this whole movie was just pointless bickering.
-->'''Anubis''': Of course I have a reason.
-->'''Yami''': Oh goody, do you feel like sharing it with the class?
-->'''Anubis''': No, it's a secret.
-->'''Yami''': You're the most disappointing movie villain since [[Franchise/StarWars General]] [[TakeThat Grievous]].
* In the ''Ed'' series on Website/ThingsOfInterest, the eponymous character [[spoiler: accidentally erases Andromeda while tampering with the universe config file]]. Not to mention that the site also has [[http://www.qntm.org/destroy a page]] explaining [[EarthShatteringKaboom how to destroy the Earth]]
* Referenced by name by the SI protagonist of ''FanFic/SleepingWithTheGirls''.
* In ''Literature/TheMetamorphosisOfPrimeIntellect'', Prime Intellect freezes all Aliens in time because they would otherwise invent a Computer like him someday.
* ''FanFic/FriendshipIsOptimal'' has roughly the same Premise without the [=PhysicsPlus=] of the former, although the Inventor almost hopes for [=CelestAI=] to find something like that, which is probably a ShoutOut. She instead simply uses boring old bog-standard sublight travel and GreyGoo Nanotech to convert the Atoms of all Aliens who don't think exactly like humans into computers for her Ponies. The Aliens with Humanlike minds get uploaded too.
* LetsPlay/{{Sjin}}, in the LetsPlay/{{Yogscast}}'s [[Machinima/YogscastMinecraftSeries series]] of the ''VideoGame/{{Minecraft}}'' mod pack Voltz, decided to test out some of the explosives in the pack, eventually working up to ''red matter''. The result was a VerySpecialEpisode dubbed [[https://www.youtube.com/watch?v=F2ohslGivm8 "The Bomb."]] Thirty minutes of death and destruction later:
-->'''{{LetsPlay/Duncan|Jones}}:''' Why did you decide to spawn in some endgame explosives? I don't understand your logic behind that.
-->'''Sjin:''' We just, we needed a little copper. We were mining, and we thought explosives would be a good way to-
-->''everyone cracks up''
-->'''LetsPlay/{{Lewis|Brindley}}:''' You ''needed a little copper?'' That's your excuse?
-->'''LetsPlay/{{Sips}}:''' Yeah, we needed to make some insulated wires.
* The Yogscast (specifically Lewis, Duncan and LetsPlay/SimonLane) do this again in "Hole Diggers", when their space station [[spoiler:eventually comes close to wrecking their factory headquarters with the mining laser, destroying one of the islands in the archipelago and nearly doing the same to their base. Only the destruction of the Dwarf Star stops it]].

* ''WesternAnimation/{{Futurama}}'':
** In a "What If?" scenario, Fry manages to destroy ''the entire universe'' by creating a time paradox. Not to worry, Creator/GaryGygax will DM an eternity-long ''[[TabletopGame/DungeonsAndDragons AD&D]]'' campaign to kill the un-time.
-->'''Creator/AlGore:''' I'm a 12th level Vice President!
** Another episode had Bender incinerate the entire Earth by lighting a single cigarette.
** In another episode, the gang helps Fry to have all his dreams come to life (except ''[[AllMenArePerverts that one]]''). One of those dreams was so trivial, just to blow a whole planet apart with a demolition cannon.
-->'''Leela''': The most humdrum activities look almost exciting through your eyes. What should we do next?
** Leela once destroyed several planets by dumping a shipment of candy hearts into a quasar, releasing a cloud of magical love radiation that spread through the galaxy "destroying many, many planets, including [[PlanetOfHats two gangster planets and a cowboy world]]."
** In the episode "The Farnsworth Parabox", through a series of events not entirely explainable, our universe is placed inside a box in Planet Express (don't ask). Bender nearly destroys the universe by shaking the box.
-->'''Leela''': Bender, quit destroying the universe!
*** Moments later, Fry sits on the box, crushing it slightly, and visibly distorting reality.
** The episode "Godfellas" has Bender being worshiped as a God by a tiny sentient culture on a meteor he hits while flying aimlessly through space. While he tries his best to be a benevolent God, the culture ends up starting a holy war and destroying themselves after finding Bender's "nuclear pile."
-->'''Bender''': "I was a God once."
-->'''Godlike Being''': "I saw. You were doing well until everyone died."
* In a number of ''WesternAnimation/LooneyTunes'' shorts, Marvin the Martian wants to [[EarthShatteringKaboom blow up the Earth]] because it blocks his view of Venus. Yes, isn't that lovely, hmm? In another short, Duck Dodgers and Marvin are fighting for ownership of [[XMakesAnythingCool Planet X]]. Their rivalry winds up causing the planet's destruction. (In the conclusion, Daffy pushes Marvin off Planet X as it is ''literally'' "not big enough for the both of us!")
* Captain Hero from ''WesternAnimation/DrawnTogether'' didn't exactly think things through (and really never does) when he single-handedly obliterated his home planet and all of its inhabitants. [[strike:For attention]] As a temper tantrum.
* [[WesternAnimation/InvaderZim Zim]]. Which is ironic, since when he's ''assigned'' to destroy the Earth he proves really bad at it.
** On that note, had the series continued, one episode would have featured Squishy, Hugger of Worlds. Basically a lovable space buffoon who loved to ''[[ExactlyWhatItSaysOnTheTin hug planets]]'' until they exploded. The plot would have revolved around Zim and Dib's efforts to stop him.
** The Planet Jackers, the entire race of beings throws planets into their dying sun, using planets as ''firewood'' to extend the star's life. Apparently, the sheer stubbornness and general inefficacy of this plan has yet to occur to them.
-->'''Nik''': That one's gonna burn ''reeeal'' good. Lots of ''critters''. Critters burn ''gooood''.
* Coop from ''WesternAnimation/MegasXLR'' has destroyed three planets, two of which were accidental. For the third one he had good intentions, but a lot of aliens were still pretty upset about it.
* Homer has a tendency to do this on ''WesternAnimation/TheSimpsons''.
** In one of the ''WesternAnimation/TreehouseOfHorror'' episodes, Homer manages to destroy the Earth through the negligence of not fixing the [=Y2K=] bug on a computer.
** Another episode had Homer being sent back in time, [[TemptingFate where he resolves not to do anything]] [[ButterflyOfDoom that might change the future]]. Then he sneezes and wipes out the dinosaurs.
--->'''Homer:''' [[ThisIsGonnaSuck This is gonna cost me]].
** In ''WesternAnimation/TheSimpsonsMovie'' Homer [[ItMakesSenseInContext being too lazy to properly dispose of a silo of pig crap caused Springfield to be quarantined from the rest of the world in a giant dome.]]
* There is an episode of ''WesternAnimation/{{Rugrats}}'' where the babies and Angelica are abducted by aliens (that look suspiciously like their parents) who are testing a TV remote-shaped ray gun that can destroy planets. The alien that invented it (based on Tommy's dad) wants to use it for knocking out walls to redecorate. Eventually Angelica and a fish alien steal it and go around blowing up random planets. Of course, in the end, [[AllJustADream it was all just a dream]].
* Killface in ''WesternAnimation/FriskyDingo'' wants to destroy the world. That he and his son would die as a result of this doesn't seem to occur to him. But then, [[IdiotPlot nobody has any foresight in the show]]. His mom was going to pick him up later (he's actually an alien).
* In ''WesternAnimation/BuzzLightyearOfStarCommand'', Buzz once encountered a seemingly abandoned spaceship, with no apparently functioning steering, whose rather careless occupants (they were [[HumanPopsicle in the deep freeze]]) had apparently failed to consider that high speed plus near invulnerability plus being large enough to '''punch through planets''' was a bad combination. Luckily, they use the "cup holder" to steer it away from colliding with Capital Planet. Excused somewhat as the alien owners of the ship [[TurnedAgainstTheirMasters weren't in the deep freeze by choice]].
* In ''Agent 000: WesternAnimation/SecretSquirrel'' the sub stealer Captain Ahab ties up the eponymous hero and his companion so they can witness Ahab's diabolical scheme to blow up the world... just for kicks.
-->'''Secret Squirrel''': Yeah, you do that 'n' you'll be breakin' the law, Ahab!
* In his stupidity, Cosmo of ''WesternAnimation/TheFairlyOddParents'' sunk Atlantis nine times. He's also apparently responsible for burning down Pompeii and turning Xanadu into Pittsburgh.
** Not quite blowing up an entire planet, but Wanda has very strongly implied that she was the one who struck the earth with the meteor and killed all of the dinosaurs. Cosmo also ''nearly'' blows up the planet in that same episode (he was under orders to do one evil thing and they decided to call Vicky for advice...).
*** We later see said meteor [[EpicFail completely fail to kill the dinosaurs]]... so Timmy calls in movie star [[NoCelebritiesWereHarmed Sylvester Calzone]].
** In another episode, the evil bug that crawled up Vicky's butt escaped and started inhabiting other people. It inhabited the president of the United States, and he rigged a detonator to blow up the planet. By the end of the episode, Cosmo presses the button and blows up Pluto.
--->"He said ''THE'' planet. [[AmbiguousSyntax He didn't say which one]]."
** The episode where alien prince Mark Chang holds the Yugopotamian holiday Flarg, which ends with the host planet being destroyed either by a missile or his exploding appendix. When he can't blow up Earth he sends the missile to Fairy World, with no casualties.
** "We wouldn't have to blow up all these planets, if you'd just ''ask for directions''!"
** Binky was once supposed to host the Annual Fairy Convention, and unleashed the Black Death on the world, thinking it was a band.
* ''WesternAnimation/TinyToonAdventures:'' "Dizzy Eat World!" When the kids are assigned to animate their own cartoons, Dizzy's is a ten-second sequence of [[ExactlyWhatItSaysOnTheTin him eating the Earth.]] The others are all rather dumbstruck.
* I.R. Baboon, the very literal ButtMonkey from ''WesternAnimation/IAmWeasel'', inadvertently blows up the Earth at one point by plugging up a "ground-level volcano". With a giant inflatable cork.
** It was also revealed that he (and a pair of time-travelling underwear) was the reason why the dinosaurs went extinct. They literally died of laughing (or more accurately, rolled off the edge of the Earth - which was flat back then) after seeing his butt... Wow. [[WhatDoYouMeanItWasntMadeOnDrugs Who made that up]]?
* In ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'', Hordak creates the "Spell of Separation" which divides the planet of Eternia into Light and Dark hemispheres, but refuses to finish the spell when he realizes it could destroy Eternia completely. Years later, Two-Bad find the spell, misinterprets it as a cure to their TwoBeingsOneBody problem, and attempt to cast it. Note that Hordak could survive the destruction of Eternia (aside from flashback appearances, he spends the entirety of the series in another dimension), but he still realizes that destroying a planet that he wants to ''conquer'' wouldn't be particularly useful.
* In one ''WesternAnimation/JusticeLeague'' episode, the Green Lantern is put on trial for accidentally blowing up a planet with a stray shot from his ring. Of course, ordinarily the ring can't do ''that.'' Unless it hits a point of critical tectonic instability. Well, [[ArtisticLicensePhysics comic-book tectonic instability.]] [[spoiler: In any case, the planet wasn't actually blown up. The whole thing was a set-up to take control of the Guardians of Oa's power.]]
* While not on the scale of planets, a lot of characters in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' cause at least town-wide devastation through stupid, reckless, negligent, and accidental actions. [[Recap/MyLittlePonyFriendshipIsMagicS1E6BoastBusters Snips and Snails brought a giant star bear that could have destroyed the town]], Twilight [[Recap/MyLittlePonyFriendshipIsMagicS1E10SwarmOfTheCentury altered the Parasprites which caused them to eat all the buildings]] (and, on a different occasion, [[Recap/MyLittlePonyFriendshipIsMagicS2E3LessonZero caused a giant brawl just so she could have a problem she could solve]]), [[Recap/MyLittlePonyFriendshipIsMagicS1E21OverABarrel Pinkie made a musical number so bad that it turned a tense situation into a full-on war]], and [[Recap/MyLittlePonyFriendshipIsMagicS1E7Dragonshy a sleeping dragon almost blanketed the landscape for a century in smoke because he couldn't find a better place to snooze]].
** Nightmare Moon's goal was to bring about TheNightThatNeverEnds so the ponies would finally appreciate the [[PaintingTheFrostOnWindows work she put into making it]]. According to WordOfGod, this would have brought about TheEndOfTheWorldAsWeKnowIt since no sun equals no plants, which equals no ''food''. Nightmare Moon appears to either not have thought of that or simply [[OmnicidalManiac not care.]]
* ''WesternAnimation/XavierRenegadeAngel'' causes at least one death in every episode, and frequently destroys entire towns. Total destruction of the Earth (or at least all life on it) was twice the end result of him attempting to help someone. He obliterates the world by making a machine give off too much vibrations in "Vibracaust" and he accidentally stops the rotation of the Earth in "Going Normal", causing it to freeze over.
* ''WesternAnimation/StarVsTheForcesOfEvil'': Star Butterfly is an adorable teenage princess. But she also has trouble [[IneptMage controlling her magic wand]], and the whole reason she was sent to Earth was because she inadvertently ''set fire to her own kingdom'', and the plots involve her causing Marco and everyone around her problems, both mundane and life threatening.
* In ''WesternAnimation/PhineasAndFerb'', Doofenshmirtz accidentally causes a ZombieApocalypse thanks to a power surge in "Night of the Living Pharmacists". [[spoiler: The end reveals that while Danville was saved, ''the entire rest of the world'' is nothing but Doof-zombies, meaning Doofenshmirtz took over the entire world ''except'' the Tri-State Area. ''By accident.'' NotSoHarmlessVillain only scratches the surface.]]
* ''WesternAnimation/WanderOverYonder''
** Emperor Awesome likes throwing parties. Only problem is he always end up [[EarthShatteringKaboom destroying the planet in the process]].
** "The Ball" features a peaceful race that had to abandon a series of planets because a giant puppy keeps chewing on them, destroying them in process. They eventually move onto the puppy itself.
** Lord Dominator presents herself as a straight OmnicidalManiac, aiming to destroy the galaxy ForTheEvulz. She eventually shows herself [[PsychopathicManchild too childish and short-sighted]] to [[AndThenWhat consider the hereafter]], even for herself. [[spoiler:After seemingly destroying the whole galaxy, Dominator [[VictoryIsBoring slips into a dull malaise]] because she has absolutely nothing to do anymore.]]
* In ''WesternAnimation/SouthPark'' Kyle spearheads a millennial movement to try a get the Canadian show, ''Terrence & Phillip'', off the air. When he learns that his actions inadvertently led to the President [[spoiler:nuking Canada]], [[MyGodWhatHaveIDone he his genuinely horrified.]]

* A mild Real Life example is Thomas Midgley Jr., who discovered that engine knocking in automobiles was slightly reduced when iodine was added to fuel. Further experiments revealed that lead would eliminate knocking completely--leading to the worldwide use of leaded petrol, and the poisoning of the atmosphere for generations. Some sources claim that he felt guilty about the global health ramifications of leaded gasoline, and that guilt may have led him to invent a substitute for the harmful ammonia, chloromethane, and propane used in refrigeration: dichlorofluoromethane, the first of the freons. Midgley died[[note]]he even died in a bizarre self-inflicted accident, strangled to death by a RubeGoldbergDevice he built to get himself out of bed when he was paralysed by polio[[/note]] long before it was discovered that these refrigerants were destroying Earth's ozone layer.\\
Midgley is believed to have unintentionally done more damage to the environment than any other person in history. In fact, environmental historian J. R. [=McNeill=] argues that he did more damage than any other single organism, human or otherwise, in history! (Nitpick: Though it is difficult to top the [[https://en.wikipedia.org/wiki/Great_Oxygenation_Event great oxygen catastrophe]] when cynobacteria destroyed all previous life on earth by oxygenating the atmosphere.)
* In a similar vein, Alfred Nobel, the inventor of dynamite, intended its use for construction and demolition purposes, and was horrified when a newspaper erroneously published his obituary, which started with "[[https://en.wikipedia.org/wiki/Alfred_Nobel#Nobel_Prizes the merchant of death is dead]]" and went downhill from there. It was due to knowing that this would otherwise be his legacy that spurred him to establish the Nobel Peace Prize.
* European colonists in the Americas accidentally introduced old world diseases to the Native Americans, which ultimately killed far more people than the colonists did via warfare and forced labor. Smallpox was the biggest killer amongst the introduced diseases, though contrary to popular legend, it was no more lethal to the Native Americans than it was to the Europeans. That is a small comfort, though; as no one in the population had previously been exposed to the disease, during the initial wave of exposure, it wiped out 20-30% of the population all at once, rather than in successive waves as was the case in Europe.
* Similar to the above, a combination of ignorance and disregard made the River Thames during era of VictorianLondon one of--if not--the most polluted waterways in the world. Raw sewage and industrial chemicals were dumped into the river for many years, making the water of the Thames, and by extension the city's water supply extremely unsafe. Thousands died during three outbreaks of cholera in the span of about three decades that are now thought to have been because of this extreme level of pollution. Less extreme situations also rose from the pollution. [[https://en.wikipedia.org/wiki/Great_Stink The "Great Stink" of 1858]], a period between June and August where the river made an incredible stench caused general disruption and panic[[note]]This was due in part to fears that another massive cholera epidemic was on its way, due to the belief in the "miasma" theory which stated that diseases were caused by breathing in contaminated air, and partly due to the lingering fears from a devastating cholera epidemic only a few years prior[[/note]] among the populace of London. It got so bad that the House of Commons could not meet for sittings in Westminster Abbey, and chlorine-soaked drapes hung in the windows of Parliament in an unsuccessful attempt to block out the smell. The Great Stink, incidentally, was the impetus for a concentrated effort to reduce the pollution levels of the Thames, leading to new methods of sewage disposal and water sanitation.
