*** Max's M.I.D.A.S., which can [[TakenForGranite turn entire nations into gold]], reflecting his belief that money controls everything and his desire to own everything.
*** Red Ivan's H.A.V.O.C., which is a WeaponOfMassDestruction WaveMotionGun that rains down atomic fire, reflecting his despotic tactics and desire to build a new Ivania from the world's ashes.

* Creator/RumikoTakahashi wrote a short story in the early 1970's (with many of the plot elements later ending up in ''Manga/UruseiYatsura''). In this tale, three alien races all decide to blow up Earth for their own reasons and launch tiny planet-busters, all of which end up in the same person. Then they discover each other and compare notes. The Horrible Truth: Their planet-busters all work by different principles, and if they go off together in one person, they will literally destroy the universe. So the aliens, knowing of the prospect of MutuallyAssuredDestruction, all set about making sure nothing bad happens to the person with the Doomsday Devices inside him, resulting in an age of galactic peace and unity.
* ''Anime/DoraemonNobitaAndTheCastleOfTheUnderseaDevil'' deals with [[{{Deconstruction}} the logical outcome]] of an ancient Dead Hand system (see RealLife section below) outliving its creator civilization. Long time ago, there were not one but two Atlantis-like undersea civilizations: the aptly-named Atlantis, and Mu. They went to war with each other, and either Mu won, or Atlantis collapsed on its own. The Dead Hand system of Atlantis, called Poseidon, is located in Bermuda Triangle and is still fully functional. Its activation will render the world [[DeathWorld "unhabitable even for the smallest and most resilient insects"]], and the increase of severe undersea volcanic activity will be interpreted by Poseidon as "the Mu are attacking our last line of defense". So the Mu people beg Doraemon and friends in a [[DarkerAndEdgier suicide]] mission to destroy the core of Poseidon with Doraemon's future gadgets.

* ''ComicBook/SonicTheHedgehogArchieComics'' had the Ultimate Annihilator, which could erase anyone or anything from existence. Robotnik used on Knothole, but was adjusted beforehand by Snivley, trapping it in a temporal pocket dimension for a while. He then used it to erase Robotnik forever.

* ''ComicBook/{{Meanwhile}}'' has a booth called a Killitron which, at the press of a button, will kill every human outside. This, combined with the weird intricacies of quantum mechanics, allows it to be used for [[MundaneUtility practical purposes]], like [[spoiler: making ice-cream]].

* In Franchise/TheDCU series called ''[[ComicBook/LEGIONDCComics L.E.G.I.O.N.]]'', a horrific conflict is neutralized with the application of a potential destructive device. Anyone gets uppity, the device goes off and everyone suffers. Seemingly...[[spoiler: the device is just a bunch of shiny bits. It does nothing]].
%% * In ''ComicBook/TheUmbrellaAcademy'', Vanya/The White Violin, is both a MusicalAssassin and a Doomsday Device, rolled into one.
* ''Wandering Star'': [[spoiler:President Andrews destroys Earth by secretly activating the Weapon Armageddon, an old doomsday device believed to have been disarmed, to prevent Earth from being enslaved by the Bono Kiro.]]
* At one point in ''ComicBook/StarWarsMarvel1977'', the protagonists find a device that is supposed to be able to devastate the entire galaxy. It's never been tested and even its creator didn't know if it would work as designed, but when it gets triggered they destroy it anyway before it can fire. Just in case.
* ''ComicBook/PaperinikNewAdventures'' presents in Pikappa the Evronian Empire's Planetary Coolflamizer. What it does is pretty simple: in an instant, it drains an entire planet's worth of creatures dry of their emotions, winning the Evronians billions of Obedient SlaveMooks and a [[EmotionEater giant reserve of food]].
* ''ComicBook/{{Shakara}}'':
** The Succubi harvest worlds by drilling into the core of a planet with the Apocalypse Cores on their [[PlanetSpaceship cosmos crafts]].
** The Infinity Engine that the BigBad orders the construction of in the final arc is actually known as the God Engine, a galaxy-sized device that will destroy all of reality and make its creator a God.
* ''ComicBook/TheUltimates'': The Chitauri have a bomb that can destroy the whole solar system, as a backup plan in case they can't harmonize the world.
* ''ComicBook/{{Empyre}}'' reveals that the Skrulls have such a device called "The Pyre". It detonates stars, intending to wipe out their system of planets in a desperate attempt to stave off the spread of genocidal Cotati.
* ''ComicBook/TheAvengersJonathanHickman'' has the Illuminati having to make the hard choice of destroying Earths from parallel universes to stop both universes from being destroyed in a metaphysical collision called an Incursion. To this end they develop devices capable of injecting antimatter into a planetary core to detonate the whole thing. They begin stockpiling these devices.

%%* ''ComicStrip/{{Dilbert}}'': Dogbert's built a few in his time.

[[folder:Fanworks]]
* {{Creator/Peter Chimaera}}'s [[Fanfic/PeterChimaerasDigimonTrilogy DIGIMON SAVEZ THE WROLD!!1111]] features an "evil scintist" who created a machine that could destroy the world. It is up to Digimon to stop this from happening. Because the story is written in BeigeProse, the exact nature the machine isn't explained. It is, however, powerful enough to destroy a road, trapping people on an island.

* Whether he counts as a "weapon" or a "character" is hard to say, but the robot Gort from ''Film/TheDayTheEarthStoodStill1951'' might qualify. Never mind the fact that he defeated a whole unit of the U.S. Army by himself; according to Klatu, he could have destroyed the Earth if he had to.

* The title machines in Creator/FredSaberhagen's ''Literature/{{Berserker}}'' stories.

* ''Literature/TheHitchikersGuideToTheGalaxy'': Hactar's Ultimate Weapon in ''Literature/LifeTheUniverseAndEverything'' uses spacewarps to link the core of every sun in the universe to every other sun in the universe, and if triggered would cause every sun in the universe to explode. The [[AxeCrazy species]] who ordered the creation of this piece of overkill tried to use it [[TooDumbToLive to blow up one of their enemies' munitions dumps]]. Luckily, the weapon didn't actually work, because Hactar, pondering the implications of such a weapon, designed it to be a dud. Later on he got qualms about that.
* The Doomsday Clock in Creator/JohnBellairs' ''Literature/TheHouseWithAClockInItsWalls''.

* One mode of play from the ''TabletopGame/{{Paranoia}}'' rulebook for High Programmers is Doomsday, where each player has a Doomsday weapon and the ability to use it. Paranoia indeed.
* The premise of the board game Mwahahaha is to collect the items needed to activate your DoomsdayDevice on a global scale and use it to take over the world.
* ''TabletopGame/Warhammer40000'' has these. Lots of them, actually. In every size, shape, and means of destruction imaginable.
** However, you have to consider, that most of them won't even scathe a tank of that universe.
** Chaos has an actual DoomsdayDevice strategic asset for Apocalypse. It tends to hurt a lot of people when activated.
* ''TabletopGame/TechInfantry'' has these, both by name in its {{backstory}}. The Three-D, or [=DoomsDay=] Device, is a device that can [[StarKilling send a star into supernova]], destroying an entire solar system. It was used to defeat a particularly nasty {{alien invasion}}, and through the armament of huge mile-long FTL starships that can fire miniature black holes. Several races can [[ColonyDrop toss around asteroids big enough to wipe out the dinosaurs]].
* Filled quite nicely by Eldtrich Machines in the ''TabletopGame/{{Eberron}}'' ''TabletopGame/DungeonsAndDragons'' setting. What does an Eldtrich Machine do? Anything your plot demands it does, really.

* In ''TabletopGame/{{Ravenloft}}'', Azalin the lich-king constructed an arcane mechanism that's actually called a "Doomsday Device" ... only it's intended to let Azalin break ''out'' of the Land of Mists, not destroy it or hold it for ransom. (Its side effects ''did'' wipe out a major city, though.)
* In ''TabletopGame/{{Traveller}}'', the Sun Trigger of the Darrians, which can cause solar flares in a star and devastate its planets.

* ''TabletopGame/{{Exalted}}'':
** The Sword of Creation (aka the Realm Defense Grid). Once fired up you can use it to obliterate entire armies of powerful supernatural monsters. It does also chew up the landscape though, so it is not fit for everyday use.
** There's also the Daystar, the gigantic flaming mecha that serves as Creation's sun and the Unconquered Sun's base of operations. It has a cannon that, if fully powered up, will destroy all of Creation. The Unconquered Sun has only used it once - during the days of prehistory, to destroy the blighted copy of Creation a Primordial tried to use to replace the genuine article - but it's noted that, should the world fall to the Yozis, he may have to use it again.

* In ''TabletopGame/GeniusTheTransgression'' a high level [[MadScientist Genius]] can build one of these, making it an option for players.

* The ''Sons of the Patriots'' system in ''VideoGame/MetalGearSolid4GunsOfThePatriots''. Every weapon, military vehicle, and even soldiers and mercenaries are integrated with a system that allows any piece of equipment to be used only by designated operators. Stolen equipment is completely useless, and commanders can selectively revoke soldiers' permissions to equipment when they disobey orders. The system also includes a limited form of mind control that makes soldiers almost fearless and immune to pain. While it's presented as an effective solution to put an end to the activities of warlords and rogue units, as well as making armies more efficient, things look completely different once the terrorists get the master password to the main server. [[spoiler:With the press of a button, Ocelot shuts down every organized military force in the world with only his personal mercenary companies having a complete monopoly on military capability. The first three of five levels the heroes try to stop him, but ultimately fail as Ocelot takes control of [=SoP=] and effectively [[TakeOverTheWorld rules the entire world]].]]
* ''VideoGame/SonicAdventure2'' centered around Eggman trying to get the Chaos Emeralds to power the Eclipse Cannon, which packed enough punch to [[DefaceOfTheMoon blast a chunk out of the moon]]. [[spoiler:Things went FromBadToWorse when it turned out gathering all seven activated another program that turned the ''entire ARK Space Station'' into a Doomsday Device by initiating a ColonyDrop.]]
* ''VideoGame/{{Singularity}}'' has the E99 Bomb, an explosive device the size of a football that represented the Soviet Union's answer to America's military superiority. In an AlternateHistory, Nikita Khruschev deployed it against the US East Coast in a preemptive attack. There was no more East Coast after that.
* One of the songs in ''VideoGame/MegaManZX'' is even called ''Doomsday Device''. It's a pretty awesome track. Have a [[https://www.youtube.com/watch?v=-UWkxTmGcyw listen.]]
* In ''VideoGame/WithinADeepForest'', your goal is to stop a bomb designed to freeze the entire world. There is a time machine in the game. [[BadFuture Guess where]] [[SlippySlideyIceWorld it leads]]?
* In ''VideoGame/MetroidPrimeHunters'' The Alimbic built the Omega Cannon to stop the monster Gorea, but decided against using it for fear that Gorea would be able to mimic the cannon's power. In the game proper the Omega Cannon is the only thing that can harm the otherwise invincible Gorea.
* In the ''Franchise/{{Nasuverse}}'', the alchemists of Atlas are said to possess a rather large stockpile of {{doomsday device}}s, built to fight back against whatever they predict will end the world. And, later, against their previous {{doomsday device}}s which are now part of how the [[TheWorldIsAlwaysDoomed world will end]].

* One of the premises of the ''Franchise/{{Halo}}'' franchise is that all sentient life in the galaxy will end if the titular Halo rings are fired. [[spoiler:It was used to ''starve'' a galaxy-spanning EldritchAbomination of viable hosts, as a last resort. The Halo system's second function is to ''recreate'' most of the sentient species it killed, though civilization had to start over.]]
* ''VideoGame/DwarfFortress''. Build your own doomsday machine. Envelop the world in fire and water and then mix them both and bury the world under a bed of obsidian. The type of doomsday device you make is limited only by your imagination and how many pathetic minions you kill trying to build it. The most infamous example would be Project "Fuck the World" of LetsPlay/{{Boatmurdered}}, which flooded the surface map with magma.
* The ''VideoGame/TeamFortress2'' maps Gravelpit and Nucleus are fought over these. The former is a [[EnergyWeapon Ray Gun]]. The latter is...a gigantic spinning whirligig of light. Hanging over a radioactive pit. It's quite pretty.
* In ''[[VideoGame/{{XCOM}} X-COM]] Interceptor'', you eventually discover that the aliens are building a giant, invincible Doomsday Machine, one shot from which will raze the Earth, killing everything and everyone there. Of course, it's ''invincible'', so you can't directly harm it. The only solution X-Com scientists can come up with is the Nova Bomb, a ''human'' Doomsday Device that instantly causes a star to explode, wiping out everything in the solar system. Of course, [[VideogameCrueltyPotential there's nothing preventing you]] from using it on solar systems that ''aren't'' harboring the alien Doomsday Machine...
* In ''VideoGame/HalfLife2'', the Citadel becomes a bit of one, since it [[spoiler:explodes - solely and completely because the energy from the explosion would help tear open a portal between Earth and the Combine home dimension. If that were to succeed, the human race would be utterly obliterated in ''minutes'', once and for all, no rematches no second chances.]]
* ''VideoGame/AttackOfTheMutantPenguins'' has the Doomscale, a giant scale for balancing penguins on. If too many alien penguins pile on and set it out of balance, it's GameOver.
* The System Killer in ''VideoGame/SwordOfTheStars'' is ExactlyWhatItSaysOnTheTin. Given that the playable factions can only scour planets clean of life, it's very much an OutsideContextProblem. Supplementary material states that it was a tool of war by some {{Precursors}} that... "lost its way".
* The ''Galactic Armory'' [[GameMod mod]] for ''VideoGame/StarRuler'' adds in several flavors of doomsday devices, most of which belonged to the [[AbusivePrecursors Remnants]]. Massive battle stations that can drain the energy of an entire fleet from several AU away, causing the ships to go derelict. There are also stations that can remotely detonate planets. Good luck taking them over though, because they are typically guarded by an entire fleet of Remnant ships. Players can also build a variety of superweapons, such as the Superlaser or the Planet Buster missile, which are more than capable of razzing the surfaces of worlds in an instant - or making them simply [[EarthShatteringKaboom explode]]. Once ship scale begins to [[PlanetSpaceShip exceed five hundred]], pretty much any weapon is capable of killing everything on a planet, instantly. Build a ship big enough and it can [[StarKilling destroy stars]], or the obliterate quasar at the center of the galaxy, [[ApocalypseHow destroying pretty much everything in the galaxy]]
* In ''VideoGame/StarTrek25thAnniversary'', Kirk and his crew have to deal with an asteroid that is an orbiting nuclear missile base that threatens to bombard a planet it previously devastated centuries ago. The solution proves to be using a computer virus found in its computer system to interfere with its launch program to make sure it misses the planet.

* ''VisualNovel/{{Sunrider}}'' has two examples:
** The Paradox Core is a giant PACT space station that can destroy entire systems by collapsing a star into an artificial black hole. [[spoiler:The Solar Alliance reverse-engineers a downscaled version called the Tactical Paradox Warhead, a bomb capable of blowing up a planet.]]
** The Sharr’Lac is an [[LostTechnology ancient Ryuvian dreadnought]] that can destroy everything within a half-lightyear radius via a powerful energy pulse. [[LivingRelic Sola]] reveals that there used to be entire fleets of similar ships, and that they could potentially destroy the universe if they all fired at once. To prevent this, the Ryuvian Emperors installed safeguards so that only a daughter of the royal bloodline could activate a Sharr’lac, [[PoweredByAForsakenChild at the cost of her life]].
* In ''VideoGame/{{Stellaris}}'', you can build Colossus which is this, and there are 5 different flavors of doom to pick from, depending on your empire ethics. [[TheWallAroundTheWorld Global Pacifier]], [[DepopulationBomb Neutron Sweep]], [[TheAssimilator Nanobot]] [[UnwillingRoboticisation Dispersal]], [[MindControlDevice God Ray]] or vanilla flavor [[EarthShatteringKaboom Planet Cracker]]? Take your pick! The ''Nemesis'' DLC ups the ante by allowing empires to become a crisis and existentially threaten the entire galaxy with two more doomsday devices. The first is the Star-Eater, which consumes entire stars and collapses them into black holes, harvesting a vast amount of dark matter and destroying every planet in the system and every non-Star-Eater ship in the system. This dark matter is vital to the other doomsday device, the Aetherophaesic Engine, which when fully completed wipes out all life in the galaxy and snuffs out every star to destroy the barrier between reality and the Shroud, allowing its builders to enter the Shroud, conquer it, and become gods, thus winning the game.

* Vegnagun in ''VideoGame/FinalFantasyX2'' was created during the Machina War between Bevelle and Zanarkand, but was never used. The antagonist, [[spoiler:Shuyin]], wants to use it to wipe out the world [[WoobieDestroyerOfWorlds so no one can put him back in the absolute hell he spent the past millennium suffering]]. If you take too long to win the final battle, [[NonStandardGameOver it goes off, and Spira is obliterated]].

* This is occasionally a problem on ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius''; fortunately, [[AbsentMindedProfessor Professor Calamitous]] is unable to finish anything he starts, leaving Jimmy a way to somehow save the day.

** In "X" Professor Chang uses the stolen Zynothium to power a giant laser cannon, which he intends to use to destroy the city because... [[ForTheEvulz reasons]].
** In "Employee of the Month" the Source has [[EarthShatteringKaboom a bomb that can blow up a planet]], which it has labelled "The Destructotron".

* Apparently, the [[RedsWithRockets Soviet Union]] had a semi-autonomous system set up during the Reagan years called [[http://www.wired.com/politics/security/magazine/17-10/mf_deadhand?currentPage=all# Perimeter]]. The purpose of this system was so that, in the event of nuclear war, the country's nuclear arsenal could be deployed quasi-automatically in response to a nuclear attack on Soviet soil, regardless of whether or not the Soviet leadership was even still alive - thus allowing the Soviet nuclear arsenal to function as a doomsday device. [[Film/DrStrangelove Sound familiar?]]

* In ''WesternAnimation/SheRaAndThePrincessesOfPower'' it's eventually revealed that the [[{{Precursors}} First Ones]] were [[AbusivePrecursors xenophobic imperialists]] who invaded Etheria and modified it's natural magic with technology to convert the entire planet into a superweapon against the rest of the universe. The climax of the final season involves disarming it once and for all, freeing up the restrained magic and restoring the world to what it should have been all along.

* ''Anime/TheMysticalLaws'': The appropriately named "Ultimate Destruction Weapon" creates a fireball 400,000 times as hot as the sun's core and throws it behind enemy lines. The Godom board of directors even explains that with this weapon, they can wipe out an entire continent at will. However, Leika Chan warns that the weapon will affect the Earth's crust ''and'' core, slowly rendering it uninhabitable, to no avail.

* In ''Series/StarTrekStrangeNewWorlds'', the first episode deals with the crew of the ''Enterprise'' learning a pre-warp species has learned to make a warp core and decided to use it as a bomb. The episode deals figuring out how they did that and stopping it.

* ''VideoGame/SonicAdventure2'' centered around Eggman trying to get the Chaos Emeralds to power the Eclipse Cannon, which had world-destroying properties. [[spoiler:Things went FromBadToWorse when it turned out it activated another program that turned the ''entire ARK Space Station'' into a Doomsday Device by initiating a ColonyDrop.]]
* ''VideoGame/{{Singularity}}'' has the E99 Bomb, an explosive device the size of a football that represented UsefulNotes/'s answer to America's military superiority. In an AlternateHistory, Nikita Khruschev deployed it against the US East Coast in a preemptive attack. There was no more East Coast after that.

* In ''WesternAnimation/ExoSquad'', the BigBad [[UsefulNotes/AdolfHitler Hitler]]-wannabe Phaeton constructs a DoomsdayDevice to blow up the Earth, should the Terrans come close to recapture it. Bat-shit insane as he may be, he actually has a good motivation for this, as destroying Earth is his way of retaliating for [[spoiler:destruction of Mars, ''de facto'' Neosapien homeplanet]].

* In ''WesternAnimation/{{Futurama}}'', the Professor has around a dozen of these lying around Planet Express. His personal favorite being the Sphere-o-Boom. Occasionally he even uses them.
-->'''Prof. Farnsworth''': I suppose I could part with ''one'' doomsday device and still be feared.

* ''VideoGame/EvilGenius'': Your win condition is to build a DoomsdayDevice that will hold the whole world hostage. There are three possible devices to build: a Gravity Disruptor (uses some kind of moon-tethered ray to force anti-gravity over a large area), an Earthquake Ray (strong enough to crack open the tectonic plates and erupt lava), and an ID Eliminator (that basically turns everyone into your minion, most of whom are genetically overwritten to a single phenotype).

* The ''Sons of the Patriots'' system in ''VideoGame/MetalGearSolid4''. Every weapon, military vehicle, and even soldiers and mercenaries are integrated with a system that allows any piece of equipment to be used only by designated operators. Stolen equipment is completely useless and commanders can selectively revoke soldiers' permissions to equipment when they disobey orders. The system also includes a limited form of mind control that makes soldiers almost fearless and immune to pain. While its presented as an effective solution to put an end to the activities of warlords and rogue units, as well as making armies more efficient, things look completely different once the terrorists get the master password to the main server. [[spoiler:With the press of a button, Ocelot shuts down every organized military force in the world with only his personal mercenary companies having a complete monopoly on military capability. The first three of five levels the heroes try to stop him, but ultimately fail as Ocelot takes control of [=SoP=] and effectively rules the entire world.]]

* This is occasionally a problem on ''WesternAnimation/JimmyNeutron''; fortunately, [[AbsentMindedProfessor Professor Calamitous]] is unable to finish anything he starts, leaving Jimmy a way to somehow save the day.

* ''Series/BlakesSeven''.
** In "Countdown", the Federation have hidden a solium bomb that will kill everyone on the planet with radiation poisoning if they rebel. The rebels attempt to seize the control room before it's activated but fail, and the plot involves a RaceAgainstTheClock to locate and disarm the bomb.
** Another such weapon is used to protect a society of pacifists in "Volcano". They threaten to detonate the device if any aggressor attempts to land on their planet.
** In "Orbit", a MadScientist offers his Tachyon Funnel to Avon, a device that can destroy any planet at any range, enabling him to crush the Federation with ease. Of course, [[FailureIsTheOnlyOption it's never that easy...]]

* The eponymous "Doomsday Machine" from ''Series/StarTrekTheOriginalSeries'', an ancient, almost impervious, save for its ''WeaksauceWeakness'', planetoid sized tube of neutronium which fires a beam of pure antiproton and which literally eats planets for breakfast.

*** Max's M.I.D.A.S., which can turn entire nations into gold, reflecting his belief that money controls everything and his desire to own everything.
*** Red Ivan's H.A.V.O.C., which is a Weapon of Mass Destruction Wave-Motion Gun that rains down atomic fire, reflecting his despotic tactics and desire to build a new Ivania from the world's ashes.

*** Zalika's V.O.I.D., a device that collects the thoughts of humanity (and turns them into brainwashed zombies), reflecting her belief that humanity is already complacent and needs someone brilliant to rule them.

* On ''The Great Space Chase,'' a serial on Filmation's ''WesternAnimation/MightyMouse'' reboot, a Doomsday Device is coveted by the villain Harry the Heartless (Oil Can Harry) while under delivery of Princess Pearl (Pearl Pureheart) and the protection of Mighty Mouse.

* On ''The Great Space Chase," a serial on Filmation's ''WesternAnimation/MightyMouse'' reboot, a Doomsday Device is coveted by the villain Harry the Heartless (Oil Can Harry) while under delivery of Princess Pearl (Pearl Pureheart) and the protection of Mighty Mouse.

** The Darksaber ([[NamesTheSame not to be confused with]] the black-bladed lightsaber) deserves special mention; it was supposed to be just the "giant planet-destroying laser" part of the Death Star, but the builder cheated his contractors and it was shredded in an asteroid field without ever firing a shot.

-->-- '''Wiki/SCPFoundation''', [[http://scp-wiki.wikidot.com/scp-804 SCP-804]]

The nature of the Doom this device will unleash on the world does not matter until the device is actually activated. It rarely is, outside of {{deconstruction}}s or [[AndManGrewProud backstories of ruined worlds]]. [[ApocalypseHow It can essentially do anything]], as long as the end result is global or near-global destruction. An EarthShatteringKaboom, an army of {{nanomachines}}, a ZombieApocalypse, [[WeatherControlMachine Weather Control]], [[EnergyWeapon Frickin' Laser Beams]], or a particularly large HordeOfAlienLocusts. It's the scale that makes it a Doomsday Device. Typically, a villain will construct one that [[PersonalityPowers best reflects his personality]].

* ''Series/WonderWoman'': In "The Man Who Made Volcanoes" from Season 2 (1977), the Amazon uses her whole body to block a ray from a massive volcano-inducing raygun, ending a threat to countries around the world. Another doomsday device from that series involved a character named Andros whose spaceship would destroy the world if he was not released from Nazi custody in time to defuse it ("Judgment from Outer Space", Season 1).

* One of the ''Manga/{{Doraemon}}'' movies deals with [[{{Deconstruction}} the logical outcome]] of an ancient Dead Hand system (see RealLife section below) outliving its creator civilization. Long time ago, there were not one but two Atlantis-like undersea civilizations: the aptly-named Atlantis, and Mu. They went to war with each other, and either Mu won, or Atlantis collapsed on its own. The Dead Hand system of Atlantis, called Poseidon, is located in Bermuda Triangle and is still fully functional. Its activation will render the world [[DeathWorld "unhabitable even for the smallest and most resilient insects"]], and the increase of severe undersea volcanic activity will be interpreted by Poseidon as "the Mu are attacking our last line of defense". So the Mu people beg Doraemon and friends in a [[DarkerAndEdgier suicide]] mission to destroy the core of Poseidon with Doraemon's future gadgets.

* In ''WesternAnimation/SheRaAndThePrincessesOfPower'' it's eventually revealed that the [[{{Precursors}} First Ones]] were [[AbusivePrecursors xenophobic imperialists]] who invaded Etheria and modified it's natural magic with technology to convert the entire planet into a superweapon against the rest of the universe. The climax of the final season involves disarming it once and for all, freeing up the restrained magic and restoring the world to what it should have been all along.

* ''WesternAnimation/KimPossible'':
** Bustig these kind of devices is pretty much the titular heroine's hobby, with Dr. Drakken the major builder of them.
** The best is the machine that sucks the entire planet dry of breathable oxygen. It's activated once, is quickly destroyed, never referenced ever again, and didn't make any sense in the original episode at all.

* Nimnul from ''WesternAnimation/ChipNDaleRescueRangers'' loved to make these ("They don't take a MadScientist seriously until he blows up a city or two," he tells his nephew), and every time they were powered by something more and more bizarre. His first one was powered by [[ItMakesSenseInContext petting cats]].

* ''WesternAnimation/TeenTitans2003'': In the first season finale has Slade unveil his chronoton detonator, a machine that can permanently stop time across an entire city. [[spoiler:It turns out to be a fake; making the Titans ''think'' he had a DoomsdayDevice was all part of a BatmanGambit.]]
