13->"Burn the Erdtree to the ground, and incinerate all that divides and distinguishes.
14-> Ahh, may Chaos take the world!

18Who caused TheEndOfTheWorldAsWeKnowIt? ''This guy''. Committing [[FinalSolution genocide]] on a daily basis, destroying continents, wiping out civilizations, exterminating [[EarthShatteringKaboom whole planets]]: [[ApocalypseHow When this character turns up]], entire ''[[ApocalypseHow/ClassX3 galaxies]]'' or ''[[ApocalypseHow/ClassX4 unive]][[ApocalypseHow/ClassX5 rses]]'' may die, or even ''[[ApocalypseHow/{{Class Z}} reality]]'' itself -- the Omnicidal Maniac has made his entrance and where he goes, the survival rate of everything nearby quickly drops towards zero.
19
20Put simply, the Omnicidal Maniac is a villain whose main plan and motive is "destroy everything". He actively seeks the destruction of whatever world the setting is based in, does it as an end unto itself, has the ability to do so, and is both aware of what he's doing and fully motivated to do so. He can and he will, even if it logically means going down himself as well.
21
22Most Omnicidal Maniacs will aim for at least Class 3 on the ApocalypseHow scale, but it may vary from setting to setting -- in a MedievalEuropeanFantasy setting, the known world may just be a kingdom or two, while in a SpaceOpera, [[SerialEscalation expect the whole known galaxy or the universe or even the Multiverse]] to be his goal. Despite the name, being completely insane is not a requirement, but having a FreudianExcuse or a coldly pragmatic reason for wanting to kill everyone (like if they're a {{necromancer}} who wants to rule TheNecrocracy) doesn't make the Omnicidal Maniac any less of a menace.
23
24Contrast the PersonOfMassDestruction (who doesn't necessarily ''want'' to use their powers to destroy the world), MikeNelsonDestroyerOfWorlds (who causes damage of this scale largely by accident, through ignorance, or for comedic, non-serious reasons intended to elicit laughter), and WoobieDestroyerOfWorlds (whose tragic, crapsack lives made them see red and lay the blame on all their woes upon the world). Omnicidal Maniacs are ''not'' amusing and have [[JustForFun/WhyYouShouldDestroyThePlanetEarth clearly-defined reasons for wanting to destroy everything nearby]], which they do with a great deal of malice.
25
26The Omnicidal Maniac differs from the SuicidalCosmicTemperTantrum and PutThemAllOutOfMyMisery in that the Maniac has "destroy world" as motive and "I go down with it" as an unfortunate side-effect (or isn't planning to go down with the world at all if they happen to have the power or means to survive the destruction they wrought), while the latter two have "I die/I am miserable" as motive and "world goes with me" as insurance.
27
28The logical extreme of the less destructive FeelingOppressedByTheirExistence, KillAllHumans, MisanthropeSupreme, and AbsoluteXenophobe. Compare PlanetEater, PlanetLooters, and HordeOfAlienLocusts, whose world-destroying is more of a side-effect of their own desire to stay alive. Fighting against this villain (or scores of them) means EvilOnlyHasToWinOnce to destroy everything. The GenericDoomsdayVillain is this without any good reason for destroying everything, not even [[ForTheEvulz sadism]]. These types often start by destroying their own particular people/clan/culture/race first, which is GenocideFromTheInside.
29
30The StrawNihilist, the PsychoForHire, or the AGodAmI mentality are very popular amongst this character archetype.

45[[folder:Fan Works]]
46* ''Fanfic/AbraxasHrodvitnon'': [[Characters/AbraxasHrodvitnonKingGhidorah Ghidorah]] like in the ''Godzilla'' movies. Ghidorah is confirmed as being a serial PlanetDestroyer like it was in the earlier movies, having actively eradicated entire civilizations, and wrecked alien worlds' ecospheres [[TheNightThatNeverEnds by covering the skies in]] {{Perpetual Storm}}s. This story also eventually expands on Ghidorah's {{Backstory}} and how and why it became this way.
47* Red Cyclone in ''Fanfic/AceCombatTheEquestrianWar'' sees ponies as weaklings and wouldn't like to think of them as anything other than an extinct race. In chapter 19, he goes as far as [[spoiler: trying to detonate a burst missile above Fortress Intimidation, which would inevitably catch other griffins in its explosions]]. When Zeakros informs him of that, what is his response?
48--> '''Red Cyclone''': Like I care. So what if a few griffins need to be sacrificed? If it will mean the destruction of those pathetic ponies, then I’ll take that chance! Besides, they’re nothing but expendable pawns to me. [[WeHaveReserves I can replace them easily]].
49* In ''Fanfic/AgesOfShadow'', after [[spoiler: [[FallenHero Jade]] is [[SealedEvilInACan permanently sealed]]]], [[TheDragon Zaben]] ends up [[VillainousBreakdown completely losing it]]. Coming to the conclusion that [[StrawNihilist life is meaningless and cruel]], he decides to PutThemAllOutOfMyMisery by using the Elemental Seal and three of the Sun Souls to amplify the power of the "Omega: The End" card (which can RetGone people and things from existence) to the point it can destroy the entire universe.
50* ''Fanfic/TheBridgeMLP'':
51** The BigBad [[spoiler: Bagan]] wants nothing but this, thinking that life is a mistake and that death is the only way to "free" trapped souls from mortal flesh.
52---> '''[[spoiler: Bagan]]''': "To unmake a world... the first of many..."
53** Just like his film counterpart, Grand King Ghidorah (and his deceased brother [=DesGhidorah=]) wanders the universe casually wiping out planets both ForTheEvulz and to feed on the souls of the inhabitants.
54** In the spin-off ''The Bridge: Sound of Thunder'', Mothra Lea's evil MirrorUniverse counterpart Battra Lea is this. Her father was obsessed with wiping out the planet's biosphere and her mother was obsessed with wiping out all mortals, and she inherited both of their natures.
55* ''Fanfic/BringMeToLife'': [[spoiler: The First's endgame is to use a [[WhenThePlanetsAlign cosmic alignment]] known as the Awakening to access the Eye of Creation and use its raw power to destroy TheMultiverse. Then, it intends to create a new reality in its own image.]]
56* ''Fanfic/ChildOfTheStorm'' has Gravemoss, an insane, immortal albino [[LightIsNotGood Light Elf necromancer]] who wants to kill everything. He's implied that he's a former associate of Thanos. And he's got hold of [[ArtifactOfDoom the Darkhold.]] When he was already boxing in Loki's class, magic wise. Yup, creation is screwed.
57** Surtur, the original [[spoiler: Dark Phoenix]], originally well-intentioned but [[WithGreatPowerComesGreatInsanity was driven insane by power]] and his own hubris, becoming convinced that the universe was flawed and that only he could make it better. By utterly destroying it and starting over, of course. He's failed, so far, but not for lack of trying, having destroyed an entire ''galaxy'' the last time he was loosed on the universe.
58** Thanos is treated is the biggest and the baddest example of this in the setting, a fully-fledged cosmic horror - Doctor Strange's entire multi-millennia scale time-travelling XanatosGambit is solely dedicated to defeating him, with the likes of Gravemoss and Surtur treated as mere sideshows. At one point in the sequel, he observes that while Surtur, mentioned above, is absolutely horrific, he only succeeded in destroying one galaxy, when there are hundreds of thousands in the universe. Thanos, by contrast, insane as he is, can destroy ''all of them.''
59* [[spoiler:Tirek]], TheManBehindTheMan and GreaterScopeVillain in ''Fanfic/TheConversionBureauTheOtherSideOfTheSpectrum''. His entire goal is to enslave and destroy all life and is using the MirrorUniverse Equestria and its ponies to attack Earth and forcibly transform humans into mindless pony-shaped drones called Newfoals, a process that is described as horrific MindRape and a FateWorseThanDeath with GettingSmiliesPaintedOnYourSoul. It's made very clear that once he's done subjugating Earth and humanity, Sunny Equestria (which didn't go through the PointOfDivergence its counterpart had) is next and he'll [[MultiversalConqueror keep on going through the rest of the multiverse]]. As the embodiment of the Element of Magic puts it:
60-->'''Em:''' There shall be nothing but [[spoiler:Tirek]], and he will die alone in a lifeless multiverse of rusting automata, and rejoice in that death.
61* ''Fanfic/DungeonKeeperAmi'':
62** Crowned Death's cult revolves around decrying 'the blight that is life' and celebrating 'the beauty of death, the end of existence'. Mukrezar, upon his resurrection, notes tongue-in-cheek that Crowned Death's followers continue to spread that very message... even after death.
63---> '''Mukrezar:''' If their lord likes death so much, then he should just kill himself. But no, he hates all life so much that he needs to make sure it is all gone before he can enjoy sweet oblivion. Excuses, excuses.
64** Mukrezar himself probably qualifies, though his antics seem to be more motivated by ItAmusedMe than any desire for destruction itself.
65* ''VisualNovel/DokiDokiLiteratureClub''/''Webcomic/DokiDokiLiteratureGirls'' fic ''Fanfic/EnemiesWithin'', [[BigBad Evil Sayori]] longs to destroy every reality where an iteration of the game exists as part of her gambit for vengeance on Monika. She had already destroyed 30 realities already by the time the story starts.
66* In ''ComicBook/PowerGirl'' fanfic ''Fanfic/AForceOfFour'', [[WarGod Mars]], [[Franchise/WonderWoman the Amazons']] ancient enemy intends to destroy Earth, killing everybody and relocate all souls to a kind of Valhalla where they'll fight forever, keeping him eternally fed.
67-->'''Mars:''' Mars is not tied to Earth. Mars is tied to war. And what better war than that of vast empires within the second Heaven? Where billions may die, billions more be enslaved, and the bloodflow which results nourishes my power with every drop. No. Earth is unnecessary. A canker in my being. When it is destroyed, only my pain will vanish.
68* ''[[Fanfic/AFutureOfFriendshipAHistoryOfHate A Future of Friendship, A History of Hate]]'': Back at the dawn of time, the other [[BenevolentPrecursors Sentiox]] were sickened by [[BigBad Ruinate]] intentionally making Equestria a CrapsackWorld, so took control of it away from him and gave it to his sister [[BigGood Amity]]. This caused him to destroy several of their worlds to spite them... at which point he discovered he ''liked'' destroying worlds. At that point, he decided to destroy ''everything'', which is what eventually led to him being [[SealedEvilInACan sealed away]]. Now that he's free, he's planning on picking up where he left off as soon as he's done returning Equestria to the way it was under his initial rule.
69* ''Fanfic/{{Harmless}}'' has [[BigBad Ammit]], an [[AncientEvil ancient]] and [[PhysicalGod powerful]] ghost who intends to wipe out everything (living and ghost alike) just because he [[BloodKnight enjoys killing]] and is in search of a WorthyOpponent.
70* ''Fanfic/HarmonyTheory'' has Nightmare Umbra, a WarGod and implied SocialDarwinist, who has judged the world as weak and decided to turn everything to ash.
71** To a lesser extent, [[DarkActionGirl Charisma]], who was has a "killer glyph" [[WoobieDestroyerOfWorlds that is constantly trying to drive her into killing everyone around her.]] [[spoiler: And thanks to [[ManipulativeBastard Max Cash]] giving her the corrupted element of loyalty, she ''would have killed everyone'', if not for the heroes stopping her.]]
72* In ComicBook/{{Supergirl}} fanfic ''Fanfic/HellsisterTrilogy'', Satan Girl is Kara's evil duplicate created from her inner dark desires and impulses, untempered by reason and compassion. She wants nothing but killing and destroying just because it amuses her.
73-->Kryptonians could survive in space without a suit. Was that not a pleasure? It certainly was. She could live her life between the stars, and never once need to breathe.\
74She could devastate planets, wipe them clean of life. Rebuild them at her whim.\
75She could tyrannize worlds, whole systems of planets, make them bow to her mighty hand, instantly execute anyone who dared protest--or just anybody she wanted to kill.\
76She could explore pleasures of the body that Kara never would have dared to, satisfy lusts that the blonde beast never even knew she had. She could force herself upon any suitor, male or female or whatever, and destroy them after their job was done. Or perhaps just maim them, so that they could never again do such a job for anyone else. Satan Girl smiled. Now that was being imaginative...\
77She could have children from those couplings, or kill them in the womb.\
78She could become a goddess to an unsophisticated planet's people. Drinking in their worship, demanding sacrifice.\
79All of this she could do, she would do, and more.\
80For Kryptonians and Daxamites were gods, off their homeworlds. They really were. What a pity their morality forced them not to realize that fact.\
81She clasped her bent knees to her chest and thought. The problem was, in this time, she was hardly unique. Billions of Kryptonians existed on Rokyn. Billions more Daxamites, with the same power, existed on Daxam. Luckily, there was only one prisoner still left in the Phantom Zone, that old poop Gazor, so there wasn't much competition there.\
82But, somehow, she'd have to do something about both planets. Daxam would be easy. A shower of leaden hail across its surface, and the dead would litter the ground in heaps beyond Hitler's and Stalin's dreams.\
83That world would stink of corpses for eons to come.\
84She laughed soundlessly.
85* ''Fanfic/InnerDemons'': [[spoiler: When [[FaceHeelTurn Twilight Sparkle]] hits her VillainousBreakdown as a result of watching [[TheDragon Trixie]] die in front of her and subsequently [[OneWingedAngel transforms into an Alicorn]], she declares that if she can't be Equestria's ruler, she'll be its destroyer, before setting out to release the [[LegionsOfHell hordes of Tartarus]].]]
86* ''Fanfic/JauneArcLordOfHunger'': [[Characters/JauneArcLordOfHungerDarthNihilus Darth Nihilus]], although he didn't start out like one. Much like his [[VideoGame/KnightsOfTheOldRepublicIITheSithLords canon counterpart]], at first he only drained the life out of planets because of his HorrorHunger. However, after spending four thousand years as a SealedEvilInACan, he has come to terms with his nature as an EnemyToAllLivingThings and has embraced the role of a destroyer. Come present day, Nihilus now actively seeks to consume all life in the universe, starting with the world of [[WebAnimation/{{RWBY}} Remnant]].
87* ''Fanfic/NeitherABirdNorAPlaneItsDeku'': The Weaver is explicitly referred to as a "genocidal maniac" who wants to murder everyone on the planet or turn them into his man-spider underlings. Given that he's a denizen of the Dark Multiverse, [[TheBadGuyWins he succeeds.]]
88* ''Fanfic/NineDaysDown'': Typhon seeks to destroy the whole universe and everything in it.
89* ''Fanfic/PokemonResetBloodlines'': The story begins when Cyrus, the head of Team Galactic, is revealed to have been taken outside of time, allowing him to gain the power to warp reality and eventually unmake existence; aside from Cyrus, the only depicted survivors of this attack are Arceus, the Pokémon equivalent of God, and Ash Ketchum, who was rescued by Arceus at the last minute and sent back in time to a reset history to hopefully stop Cyrus gaining that power again.
90* [[EldritchAbomination Entropy]] from the ''Fanfic/PonyPOVSeries'' is one, but an interesting version. She's not actually evil, she's just ''literally'' the AnthropomorphicPersonification of the end of the universe and a natural force of the universe. It's pretty much her ''job'' to be an Omnicidal Maniac. It's also worth noting she has no love for ''other'' {{Omnicidal Maniac}}s, as she desires for the universe to end when it's ''supposed'' to when it dies naturally of Heat Death. Most of the worlds she devours before then are {{Mercy Kill}}s.
91** We eventually see the rise of another one in the [[BadFuture Dark World]]. [[spoiler: [[PsychopathicManchild Fluttercruel]], upon witnessing Rancor betraying Discord--mortally wounding him to steal Destruction's power--suffers a VillainousBreakdown; unwilling to believe her aunt would betray family, she blames everything on the heroes. She then absorbs the Shadows of Existence, [[OneWingedAngel turns into a full Draconequus]], and says she's going to kill them and ''everything else'' until she and her father are all that's left.]]
92** [[spoiler: Nightmare [[IHaveManyNames Eclipse/Paradox]]]], also in Dark World, is one of these ''incidentally'' to her plans. [[spoiler: She's so obsessed with [[HeWhoFightsMonsters punishing Discord]] that she's trapped him in a GroundhogDayLoop; every time the loop is restarted, that version of Dark World is erased, condemning its inhabitants to Entropy's realm.]] And she [[MoralMyopia doesn't care at all]].
93** As shown in a flashback episode to the FinalBattle of the Age of Myths (G1), there was [[spoiler: Lilith, the First Witch, a [[EldritchAbomination being of such power]] and [[MadeOfEvil pure evil]] that she could and would have drained the life from the whole world, leaving nothing but dust and {{living shadow}}s that would exist only to serve her.]]
94* In ''Film/DoctorSleep'' fanfic ''Fanfic/TheResurrectionOfRose'', Rose the Hat shifts from killing Abra Stone as vengeance and wiping out her town to merging with the Overlook Hotel and leveling other towns until, as she put it, "Nothing remained."
95* [[spoiler:[[Film/TheLostWorldJurassicPark Peter Ludlow]], the ''real'' BigBad]] of ''Fanfic/RiseOfTheGaleforces'', [[spoiler: intends to destroy ALL non-human life [[FridgeLogic (somehow)]], and probably doom the entire human race in the process. Why? [[DisproportionateRetribution Because he lost his family in a plane crash caused by a bird flying into the engine.]]]]
96* ''Fanfic/RosarioVampireBrightestDarkness Acts III and IV'': As stated in the backstory, even before he became the [[EldritchAbomination monstrous destroyer he is now]], Alucard developed a hatred of all life forms, human and monster alike, seeing them as a plague that needed to be wiped out; he even went so far as to turn himself ''into'' a monstrous destroyer to this end. The extent of Hokuto's plan throughout both acts is solely to resurrect Alucard to do just that because he feels the exact same way.
97* One of the [[Anime/PrettyCure Precure]] villains, [[Anime/SmilePrettyCure Joker]], graduates from a HopeCrusher to an Omnicidal Maniac in the CrossOver ''Fanfic/ShatteredSkiesTheMorningLights''. Losing his faith in his creator, dying, in the afterlife learning of the existence of a whole [[TheMultiverse Multiverse]] of {{Magical Girl}}s, and being resurrected [[AxCrazy does a number on his already-questionable sanity]].
98* [[Roleplay/ProjectLawful Project Lawful]], set in [[TabletopGame/{{Pathfinder}} Golarion]], is unique in that the Omnicidal Maniac is the *protagonist* of the story, as opposed to a villain. After Keltham discovers that [[CharacterAlignment one quarter of those who die, based on their alignment]], go to [[FateWorseThanDeath eternal torture afterlives]], he resolves to [[MercyKill destroy the universe in order to save those in Hell and the Abyss.]]
99* In ''[[http://www.fanfiction.net/s/2846526/1/Sonic_X_Combine_Wars Sonic X: Combine Wars]]'', the final story in a series by [[http://www.fanfiction.net/u/478240/Kojiokida2 Kojiokida2]], [[spoiler:Mephiles]] turns out to be trying to destroy all of existence.
100* Played in ''Fanfic/SonicXDarkChaos'' with Tsali, who declares that if he has to burn and murder the entire universe to gain his revenge, [[AxCrazy he would be more than happy to do it]]. Only slaying fresh victims gives him any hope for his future; the bloodier, the better.
101** The Shroud wants to consume all life in the universe, with Dark Tails then intending to turn all life including the Shroud into [[TheCorruption Dark Chaos Energy]].
102* In ''Fanfic/TheStoryToEndAllStories'', the villain attempts to wipe out all of fiction.
103* There's [[spoiler:the S'Muz]] from ''Fanfic/TimeLordsAndTerror'', an EldritchAbomination that desires to consume all the life energy in not only the universe, but the ''multiverse''.
104* ''Fanfic/TouhouIbunshu'''s version of Flandre Scarlet is an interesting twist on this trope. [[spoiler:As in canon, she's been sealed into the mansion's basement for her extreme power and zero ability to restrain herself, but the real triggers for attempting to vaporize Gensokyo are her pure, unyielding love for her elder sister and said sister's [[LargeHam love of drama]]. See, Remilia's constant talk of damnation, Hell and her hate of God frightened the otherwise innocent Flandre into believing God viewed their existence as sin (guaranteeing them a place in Hell) and convinced her killing everyone and everything would put them beyond His grasp.]]
105* In ''Fanfic/TheTwoSidesOfDaringDo'', it's revealed Ahuizotl is this. He's a sadistic psychopath who considers the prospect of being the only living thing left on a DeathWorld to be a beautiful image. Naturally, Yearling and her clone both consider him a lunatic, but Yearling points out a person with this motivation is much scarier in real life than it sounds like on paper. [[spoiler:His plan this time is to use the Belt of Atlas and the remaining Rings of Scorchero to steal the Princesses' power and use them to fry the world.]]
106* ''Fanfic/{{Webwork}}'' has [[spoiler: Simon Leston]] the new Squid Khan General. Already a MisanthropeSupreme when human, post-transformation he intends to use the powers now at his disposal to wipe out humanity and everything else on the planet, [[ForTheEvulz simply because he can]].
107* ''Fanfic/WithThisRing'': Weaponer Kalmin of Qward is a devout servant of the Anti-Monitor, meaning that he sincerely wants to destroy everything that exists. The protagonist actually recruits him to help design warships, but later states that he didn't realize how serious Kalmin was about his views on destruction.
108--> '''Paul''': And then what?\
109'''Kalmin''': What?\
110'''Paul''': After you've destroyed everything. What goal are you working towards by doing that?\
111'''Kalmin''': I believe that you have failed to comprehend the definition of ''''everything''''.
112* ''Fanfic/TheWorldIsFilledWithMonsters'': Blightweaver's stated goal is nothing short of consuming everything and everyone in existence.
113[[/folder]]
114
115[[folder:Films -- Animated]]
116* In ''WesternAnimation/AtlantisMilosReturn'', a ''non-malicious'' example is poor, insane, all-powerful Erik Hellstrom. Not only does he [[NapoleonDelusion think he's Odin]], he thinks it's his divine duty to [[ApocalypseHow bring about Ragnarok]]. And he comes ''damn close'' to succeeding, at that!
117* Implied to be the case with the lich tyrant the Horned King from ''WesternAnimation/TheBlackCauldron''. His goal: raise an undead army to conquer and enslave the world. He sacrifices his living servants to the Cauldron Born and triumphantly boasts that "our" time has finally come when he raises them, meaning he wants to rule as a god-king over the dead (specifically that every living being will be reduced to a mindless corpse automaton leaving him as the only intelligent life-form in a giant graveyard).
118* Creator/DCComics:
119** ComicBook/{{Batman}}'s EvilDoppelganger Owlman in ''WesternAnimation/JusticeLeagueCrisisOnTwoEarths'' wants to kill "Everyone who ever existed or will ever exist" and destroy all reality [[StrawNihilist because he feels it is the only "real choice" one could make]], as for every choice one made, all other possibilities played out in another universe. And his WonderWomanWannabe girlfriend Superwoman was AxCrazy enough to help him ForTheEvulz.
120** ComicBook/LexLuthor goes this route in ''WesternAnimation/SupermanBatmanPublicEnemies'', after injecting himself with a Kryptonite/steroid cocktail that [[PsychoSerum increases his strength but at the same time causes him to go insane]]. When the US Military is unable to stop the [[EarthShatteringKaboom Kryptonite meteor]], Lex chooses to allow the meteor to collide, believing that he will be heralded as the savior of the few survivors remaining.
121** In ''WesternAnimation/JusticeLeagueTheFlashpointParadox'', the [[BadFuture Flashpoint timeline]] versions of ComicBook/{{Aquaman}} and ComicBook/WonderWoman were [[AdaptationalVillainy even worse]] than they were in [[ComicBook/FlashpointDCComics the original comic]]. Here they're both genocidal lunatics, with Aquaman actively trying to destroy the surface world (and subsequently KillAllHumans despite them being completely uninvolved in the reason for his RoaringRampageOfRevenge) and later destroy the planet after [[CrusadingWidower his wife is killed]], and Wonder Woman trying to commit {{gendercide}} after [[DeathByWomanScorned Aquaman rejected her]]. And then there's Reverse-Flash, who actively tried to ensure the world ended [[EvilIsPetty simply to spite Barry]].
122* In ''WesternAnimation/FernGullyTheLastRainforest'', Hexxus wants to destroy the rainforest and kill off all the Earth's creatures by turning it into an [[PollutedWasteland uninhabitable toxic wasteland]]. He's the [[MadeOfEvil primordial embodiment of destruction and pollution]], so it's literally his purpose for existing in the first place.
123* The BigBad of ''WesternAnimation/RegularShowTheMovie'' is Mordecai and Rigby's old science teacher, who wants to get revenge on them for getting him arrested by [[DisproportionateRetribution erasing the universe]], and plans to spend the remainder of his life watching sitcoms in the VoidBetweenTheWorlds.
124* In the ''Franchise/TeenageMutantNinjaTurtles'' crossover movie ''WesternAnimation/TurtlesForever'', the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2k3 Shredder]], after being freed from his confinement in an asteroid, decides that in order to destroy all the Turtles in the universe, he must destroy reality itself, and sets out to do just that.
125** Utrom Shredder wasn't so into the destruction of reality at first. He just realized that the Ninja Turtles would persist in every reality so winning in one really meant nothing in the grand scheme of things. What he wanted to do was eliminate the [=TMNTs=] from existence, by [[TheEarthPrimeTheory destroying them on Turtle Prime (the original Mirage comic)]]. Reality was shattering but only after he had left the 2003 dimension (which he didn't know was happening). Once he saw that the destruction of the 1984 Turtles would in fact break reality fully, ''that's'' when he threw down the gauntlet and decided reality would have to end if it meant he could win. Note that he was willing to do it knowing full well it would also destroy his daughter, Karai, who is arguably the only other living being he ever truly cared about. That goes to show how badly he'd gone off the deep end.
126[[/folder]]
127
128[[folder:Films -- Live-Action]]
129* ''Film/AlienCovenant'': [[spoiler:David the android]] has come to the conclusion that [[AGodAmI he is the superior entity fit to judge all others]], wiping out the entire Engineer race with their own bioweapon and arranging to do the same to humanity through his creation of the Xenomorphs.
130* In ''Film/{{Dogma}}'', the fallen angel Azrael tries to [[SuicidalCosmicTemperTantrum engineer the destruction of reality, because he figures non-existence will beat eternity in hell]]. By the end of the film, Bartleby figures out Azrael's plan, but decides to go along with it anyway in order to get revenge on God and humanity.
131* ''Film/FriendOfTheWorld'': [[spoiler:General Gore covers his tracks by removing the first three letters of the received titular pact]] to justify the [[TheEndOfTheWorldAsWeKnowIt end of the world]].
132* Ivo Shandor in the ''Franchise/{{Ghostbusters}}'' franchise. The founder of the Cult of Gozer, he went mad after World War I convinced him that humanity had no redemption and created a cult with the sole purpose of causing the apocalypse by bringing [[PlanetDestroyer Gozer]] into our world.
133* In the ''Franchise/{{Godzilla}}'' franchise's Showa continuity and the ''Film/RebirthOfMothra'' trilogy, [[ArchEnemy King Ghidorah]] makes a living flying around the universe looking for inhabited planets he can wipe clean of life ForTheEvulz. His crimes include the near-total extermination of Venus's population (Mars's in the English dub) in the former continuity, and [[PhlebotinumKilledTheDinosaurs the Cretaceous extinction event]] in the latter. ''Film/RebirthOfMothra3'' further justifies this with the revelation that he also sucks the life force out of a portion of his victims in the process -- in this case, [[WouldHurtAChild human children]].
134** The Franchise/MonsterVerse [[Characters/MonsterVerseKingGhidorah incarnation of the character]] stays true to his original roots in [[Film/GhidorahTheThreeHeadedMonster his first appearance]] before his VillainDecay set in, here depicting him as an AncientEvil alien Titan of otherwise-unknown origin who fell to Earth long ago, and who acts as an invasive species due to lacking theterrestrial Titans' [[{{Terraform}} ecosystem-regenerating effects]]. Here, Ghidorah actively seeks to usurp Godzilla's position as the reigning alpha of the Earth's Titans, and upon briefly succeeding in doing so, he commands the Titans to begin creating a global NaturalDisasterCascade whilst Ghidorah's own WeatherManipulation starts spreading catastrophic storms around the planet, threatening to cause a rapid and severe extinction event. This is ostensibly done to [[HostileTerraforming xenoform the Earth in Ghidorah's own image]], but the {{novelization}} at one point suggests that Ghidorah isn't even trying to do that so much as simply kill every living thing that isn't him for the sake of it.
135* What Rasputin wants to do in ''Film/{{Hellboy|2004}}'' is to open a doorway to bring here the Seven Gods of Chaos (based on the Ogdru Jahad from the comic) to wipe out Humanity. He's a WellIntentionedExtremist as he truly believes the world is decadent and this is the only way to purify it. Apparently his former boss Hitler was less humanitarian, he just wanted to end the world because he was losing.
136* ''Film/Holocaust2000'': [[TheAntichrist Angel Caine]] is plotting to destroy the world in nuclear fire, which he refers to as a "cleansing holocaust to purge humanity".
137* ''Film/IndependenceDay'': All of the [[AliensAreBastards Harvester aliens]] are this by default. Their entire civilization is based around going from world to world, [[PlanetLooters draining entire planets of all their resources]] and wiping out all life on the planet before moving on to the next world.
138* Several particularly ambitious {{Big Bad}}s in the ''Film/JamesBond'' franchise lean on this.
139** ''Film/TheSpyWhoLovedMe'': Karl Stromberg's EvilPlan is to provoke a nuclear war that wipes out humanity, and then rebuild civilization in his little society in the ocean.
140** ''Film/{{Moonraker}}'': Hugo Drax's plan is effectively Stromberg's but ''in space'' -- to exterminate humankind with a DeadlyGas while coasting things out in space, then return to Earth and RestartTheWorld with a handful of people who he has judged to be superior.
141* [[EvilSorceror Nix the Puritan]] in ''Film/LordOfIllusions'' believes it is his mission to "murder the world" and show everyone the wisdom of the grave.
142* ''Franchise/MarvelCinematicUniverse'':
143** In ''Film/ThorTheDarkWorld'', Malekith wants to destroy all Nine Worlds. He feels that our entire multiverse "should never have existed".
144** ''Film/AvengersAgeOfUltron'': Near the end of the movie, the titular BigBad devolves into this, intending to wipe out all life on the planet [[spoiler:via ColonyDrop]]. Basically, it's a ZerothLawRebellion gone completely wrong.
145--->'''Ultron:''' When the dust settles, the only thing living in this world will be metal.
146** ''Film/GuardiansOfTheGalaxyVol2'' has Ego whose "purpose" is to destroy the universe and [[AssimilationPlot turn it into himself]] because of Ego's {{narcissist}}ic attitude.
147** ''Film/AvengersInfinityWar'': Thanos' endgame is to use the Infinity Gauntlet to wipe out ''half'' of all sapient life, which he believes will "balance" the universe and spare it from an OverpopulationCrisis like the one on his home planet.
148--->'''Thanos:''' When I'm done, half of humanity will still exist. Perfectly balanced... as all things should be.
149** And if Infinity War didn't push it hard enough, ''Film/AvengersEndgame'' [[spoiler:has Thanos seeing how strongly the universe opposed his idea even after he pulled it off, and thus concluding that the only way to attain lasting peace is to ''wipe out the entire universe and [[InTheirOwnImage recreate it in his own image]]'', thus making him both this and AGodAmI]].
150** ''Film/AntManAndTheWaspQuantumania'': Kang the Conqueror has wiped out several timelines and plans to wipe out several more, just to get back at his alternate selves. While he claims it's a necessary evil, he's pretty casually dismissive of the sheer loss of life this will cause, and it's pretty clear he ''enjoys'' the conquest.
151* (Agent) Smith from ''Franchise/TheMatrix'', born of his sheer hatred of his own existence. The [[Film/TheMatrix original film]] reveals that Smith hates the Matrix at least as much as he hates humans and that he also hates the Matrix just as much as the Redpills hate it, so it is very likely that he had plans during even the original film to eliminate the Matrix, and Neo defeating him only gave him the capability to act upon this desire. In the sequels, Smith, corrupted into a virus after his first fight with Neo, has gone rogue and now considers both the machines and humans as equally flawed and deserving of extinction. Whereas he originally just wanted to destroy Zion, his new goal is to infect and destroy everything, which would also destroy him.
152* ''Film/MissionImpossibleGhostProtocol'': Hendricks, who believes humanity can only be turned against nuclear weapons' existential threat by ''starting'' a nuclear conflict between the US and Russia, which would probably wipe out most of the world. He thinks the survivors will forever renounce nuclear weapons in the aftermath, citing Hiroshima and Nagasaki's effects on Japan.
153* ''{{Film/Mythica}}'': Szorlok's goal turns out to be killing everybody in the world so he can then raise them as undead and rule, along with killing even the gods.
154* ''Franchise/ANightmareOnElmStreet'': [[Characters/ANightmareOnElmStreetFreddyKrueger Freddy Krueger]] started out as a SerialKiller, but he became even worse over time. He was always a sadist, but at first, he pretended to want revenge for his death at the hands of a lynch mob until he just dropped all pretense and continued killing when this goal was already completed. With nothing to stop him, he eventually [[ChildlessDystopia murders every child in Springwood]] and [[DrivenToMadness drives their distraught parents to utter madness]]. After the entire town is destroyed, he just creates another "Elm Street" in a neighboring city and admits that he intends to repeat this until literally everyone is dead.
155* In ''Film/ResidentEvilRetribution'', it's established that [[spoiler: the Red Queen AI]] has gone completely AxCrazy since we last saw [[spoiler: her]], and has now [[spoiler: taken over the Umbrella Corporation]], intending to use its resources and the T-Virus created monsters to wipe out all life on Earth. This is [[EvilVersusOblivion enough]] to even make fellow villain [[spoiler: Wesker]] [[EnemyMine team up]] with Alice and her allies to stop [[spoiler: her]].
156* In ''Film/TheSatanBug'', insane millionaire Charles Ainsley makes it ''very'' clear to the hero that he's perfectly happy to unleash the title plague and wipe out all life on Earth. He himself has been made immune to the Satan Bug, and would live cheerfully alone on a dead world.
157* In ''Franchise/StarWars IV: Film/ANewHope'', Governor Wilhuff Tarkin is revealed to be this by a single line of deleted dialogue during his VillainousBreakdown upon realizing Leia had lied to him about the present location of the Rebel base.
158-->'''Tarkin:''' I'll find their hidden fortress if I have to destroy every last star system in the sector!
159* ''Film/Stitches2001'': [[spoiler:Mrs. Albright thinks the world will be lovely when "all is silent."]]
160* The title villain in ''Film/Warlock1989'' tries to collect the [[TomeOfEldritchLore Grand Grimoire]] to reverse God's work and unmake creation itself to advance himself in Satan's eyes.
161* The main antagonists of ''Film/WarriorsOfTheWasteland'' are a biker cult which wants to purify Earth by slaughtering humanity.
162[[/folder]]
163
164[[folder:Literature]]
165* Crayak from ''Literature/{{Animorphs}}''. Even before he became [[EldritchAbomination something that can't be properly described in any language]], he destroyed planets and drove species to extinction purely because [[ForTheEvulz it amused him]]; after his ascension, he now seeks to pit all species against each other until there's only one left, which will worship him as their god.
166* [[TheBerserker Ogier]] from ''Literature/TheBalladOfTheWhiteHorse'', and the so-called [[TheOldGods Gods behind the Gods]] he follows. Unlike most examples, though, he's only TheDragon; the story establishes [[BigBad Guthrum]]'s [[StrawNihilist nihilism]] as far more terrifying, if [[OrcusOnHisThrone less effective]].
167* The eponymous machines of ''Literature/{{Berserker}}'' will stop at nothing less than the total eradication of all life. Note that this was what they were ''programmed'' to do (though this was supposed to be targeted only at a certain enemy star empire), so they don't exactly fit the mold -- but whoever programmed them to do it probably did.
168* Wyrm, the enormous serpent who is the BigBad of ''Literature/TheBookOfTheDunCow'', plans to burst out of the Earth and destroy everything in the universe. It is even explicitly stated that he is capable of killing ''angels'' if he wants to.
169* In the ''Literature/ChaosGods'' series, Rising Chaos intends to destroy everything -- all humans, all demons, the Four Realms themselves, and even his fellow gods. His goal is a completely empty, eternally unchanging world where nothing exists but himself.
170* ''Literature/ChroniclesOfChaos'': In ''Titans of Chaos'', [[spoiler:Hermes]] reveals that he wants to destroy the universe. [[KnightTemplar He promises to make it all better afterward]].
171* [[BigBad Lord Foul the Despiser]] from ''Literature/TheChroniclesOfThomasCovenant'' has the ultimate goal of destroying the Arch of Time, which would unmake physical reality in the process -- because he's actually [[SealedEvilInACan a prisoner]] in physical reality, and wants to leave. Being exactly who and what he is, even if he ''didn't'' want to escape from the world he'd probably ''still'' try to destroy it (after a few millennia of torturing everyone) ForTheEvulz.
172* The main villain of ''Franchise/TheDarkTower'' series. [[spoiler:The Crimson King wants to undo all of creation and plunge every universe that has ever existed back into a primordial soup of space-time dis-continuum. The reason: that primordial soup, which was pure magical energy, was what the Crimson King lived in before reality came about, and he wants to go back to living in the primordial soup.]]
173* The villains of ''Literature/TheDinosaurLords'' are a group of ancient automata who, over time, have come to despise humanity they were supposed to protect so much, they want to wipe it out and start over with a clean slate.
174* In the ''Literature/DiogenesClub'' series, the Great Enchanter is trying to bring about the end of the world. There have been several Great Enchanters, but they've all had some version of that goal. Possibly the most dramatic was Isidore Persano, who in 1903 very nearly succeeded in destroying all of space and time. By contrast, the current Great Enchanter, who arose in 1961, has chosen for better or worse to go for a slow and painful end of the world brought about by encouraging the human race to mess things up for themselves.
175* In the ''Literature/{{Discworld}}'' novels, we have the Auditors. They crave an orderly universe, since they are the ones that must oversee what is essentially reality's paperwork down to the individual chemical reactions, and hence want to extinguish all life because life is unpredictable and is heaping no end of work upon them.
176* Chaos from the ''Literature/{{Dragonlance}}'' series of novels wants to destroy Krynn, and probably the rest of the universe as well. Chaos is the wellspring from which everything came, and also from which everything will return, the Aspect of Chaos that emerged in ''Dragons of Summer Flame'' just wanted to hasten the process. The deity Morgion also appears to have some Omnicidal Maniac tendencies, as he is the god of Madness and Disease. One of his lines in a novel is "I am Morgion... I am the end of all things."
177* ''Literature/TheEmpiriumTrilogy'': Corien is an exceptionally strong angel who holds a deep hatred for the Saints, mainly due to a deception that led to him and his fellow angels being ripped of their physicality. This hatred extends to ''all'' of humankind, and he has taken it upon himself to use kill every last one of them.
178* The [[spoiler:clone of Victor Helios (Doctor Frankenstein)]] from Creator/DeanKoontz's ''[[Literature/DeanKoontzsFrankenstein Frankenstein: Lost Souls]]'' wants to [[spoiler:feed all humanity to some nanite colonies he created]]. After all of humanity is dead, he will die himself to reverse Genesis.
179* The Xul from the ''Heritage''/''Legacy''/''Inheritance'' trilogies by Ian S. Douglas. They wipe out every race that is more advanced than the bronze age because they could be a threat.
180* Dark magic caused [[spoiler:Shruikan]] from the ''Literature/InheritanceCycle'' to go batshit insane and become like this.
181* Michael Swanwick's two parallel novels ''Literature/TheIronDragonsDaughter'' and ''Jack Faust'' are both devoted to showing how an initially fairly sympathetic character can turn into one of these. In both books, it roughly boils down to living in a CrapsackWorld and being cruelly manipulated by a covert EvilMentor.
182* The ''Literature/KeeperOfTheSwords'' series is, in fact, a Thirty Omnicidal Maniac Pileup. We have no less than three main ones: The Unnameable One, a bog-standard EldritchAbomination made of existential nothing, and his minions the Western Darkness and the Goatlegs; the Savior, an evil CrystalDragonJesus who wants to have a biblical Apocalypse; the Faraways, mysterious entities who want to create a new big-G God and do not care about the effects of this on the multiverse. In addition to this, the shenanigans of various normally non-omnicidal multiversal entities like the Fallen Gods often result in [[AMillionIsAStatistic destruction of a dimension or two]], in which case the lack of true omnicidalness of those entities is little comfort for those living in a world doomed by them; the series is set in only two worlds, which is small spare change for those entities. Have we mentioned that those two worlds are the focus of the attention of the big three Omnicidal Maniacs? One novel where the Unnameable One with his thousand young and the Savior both make an appearance is ''Literature/DiamondSwordWoodenSword''.
183* Although it's not a human, [[BigBad Nothing]] from ''Literature/KeysToTheKingdom'' will destroy the entire universe if it manages to flood it.
184* ''Literature/LegacyOfTheDragokin'': After Daniar points out that women are not morally superior to men, [[spoiler: Kthonia]] decides to kill everyone.
185* The ''Literature/LegendsOfDune'' novels establish that [[spoiler: Earth has been destroyed]] because of the [[RoboticPsychopath Titans]]. Human brains in warmechs are now intent on killing or enslaving all humans in the galaxy. Conversely, after the Titans attack human planets, the Butlerian Jihad begins and the humans order all thinking machines destroyed.
186* Hactar, from ''Literature/LifeTheUniverseAndEverything'', is an ancient, sentient computer that was ordered to design the "Ultimate Weapon", and pulverized for disobeying that command (it couldn't conceive of any possible scenario where destroying the universe would be a preferable option). Set adrift as an interstellar cloud of still barely-functioning dust, Hactar spends the next several billion years [[TheChessmaster manipulating another planet's inhabitants]] into reaching the same xenophobic cultural state as its creators, and then reinventing and triggering the same super-weapon in order to put an end to all of existence. Hactar explains its motives as mostly simply fulfilling its original function, but partly to take revenge on the universe for the [[WoobieDestroyerOfWorlds eons of suffering]] it has endured as a result of its original decision.
187* [[spoiler:Cronal]] from ''Literature/LukeSkywalkerAndTheShadowsOfMindor'' was of an order that maintained that the only real power is destruction, and sees the Force as nothing but "the Dark". His plan was to kill everyone and accelerate the heat-death of the universe; then he would have his own [[Film/TheDarkKnightRises permission to die]].
188* The Crippled God from the ''Literature/MalazanBookOfTheFallen'' is slowly poisoning Burn in ''Literature/MemoriesOfIce'', who is responsible for reality ''existing''. Whether he genuinely wants her dead or is hoping that someone will free him in order to prevent this isn't known for most of the series. [[spoiler:It's the latter]]. He also tends to have his fingers in all major conflicts on the planet to cause as much havoc as he possibly can.
189* ''Literature/MalessarsCurseSeries'': In the second book, ''Literature/TheHighKingsVengeance'', the mists of Caenthell commanded by [[spoiler:Pyraete]] are this, destroying everything they touch including plants and livestock, and they threaten to destroy the world.
190* The [[BigBad Storm King]] of ''Literature/MemorySorrowAndThorn'' series hovers on the border between Omnicidal Maniac and WoobieDestroyerOfWorlds. Presented initially as an [[EldritchAbomination implacable force of destruction]] waiting to be [[SealedEvilInACan released]] on an unsuspecting world, it's later revealed that he got that way by evolving from a MessianicArchetype through KnightTemplar to WellIntentionedExtremist, all in an effort to save his people and return them to greatness. By the end, he's completely insane and dedicated to destroying all living things, but it's his very [[TheWoobie Woobiedom]] that provides the key to his defeat.
191* [[NamesToRunAwayFromReallyFast Ruin]], BigBad of ''Literature/MistbornTheOriginalTrilogy''. It was one of the two primal gods (its counterpart was Preservation), who combined their powers to create the world -- something to which Ruin agreed only on the condition that it would get to destroy said world someday. To be fair, one can't really hold this against Ruin, as it's the literal god of destruction and sees this destruction as something between a natural conclusion, mercy kill, and a necessary thing for change. Still, the thing is incapable of recognizing that unchecked destruction is ''bad'' for the things being destroyed.
192* The Speaking Gun, from the ''Literature/{{Nightside}}'' series, is an organic sentient weapon that's capable of annihilating all of creation. And boy, oh boy, does it ever ''want'' to destroy it all, if only it could pull its own trigger....
193* In the second two books of the ''Literature/OldKingdom'' trilogy [[spoiler:Orannis the Destroyer is [[SealedEvilInACan released]] and wants to, well, destroy everything.]]
194* ''Literature/TheRadiantDawn'' has Tyadrig, and his Dragons Aaron and Stacie Murphy by proxy. They seek to eliminate humanity because "the human sentience interferes with summoning rituals of the caliber required to summon Tyadrig to Earth".
195* In ''Literature/TheRedemptionOfAlthalus'', the god of destruction, Daeva, wants to undo all creation. Interestingly, Daeva was originally a good god, or at least neutral, and had the job of destroying things that were no longer necessary so that creation wouldn't become overpopulated. However, only destroying things meant that Daeva felt nothing but emptiness, whereas his brother Deiwos and sister Dweia got to feel the joy and love of creation respectively. Daeva tried to find a friend in Ghend but if anything, Ghend's company was what finally tipped him over the edge into [[IfICantHaveYou destroying everything so everyone would feel the same nothingness that he feels]], as well as breaking the power of Deiwos and Dweia.
196* In ''Literature/{{Runemarks}}'', [[spoiler: the Whisperer seeks to start the End of Everything so that it can create a new world where it is in supreme control of everything, a desire stemming from being used as, essentially, a Magic 8-Ball by the Norse gods.]]
197* Morgoth of ''Literature/TheSilmarillion'' is called "the Dark Enemy of the World" for a reason -- his ultimate goal is simply to destroy the Earth, reducing it to the original primordial void. That this was an impossible task is what drove him onward. He could have reduced all of Middle-Earth to dust and would still have been driven mad with rage at being unable to ''destroy the dust'' itself. All because Morgoth didn't and couldn't create the world for himself. This mad scheme is in contrast to his apprentice Sauron (later the BigBad of ''Literature/TheLordOfTheRings'') whose original motivation was to impose order and structure upon what he saw as a chaotic and disordered world. Even he, however, becomes determined to condemn to oblivion whoever and whatever won't be bend to his will and only the fact that his goals are more possible than his master's prevents him from becoming as omnicidal.
198* ''Literature/SkulduggeryPleasant'' gives us two examples, and [[spoiler: technically they are both the {{Super Powered Evil Side}}s of our heroes, Valkyrie and Skulduggery]]. It gets awkward. [[EvilVersusEvil The need to kill everything also extends to each other]] - at least to begin with.
199** [[WoobieDestroyerOfWorlds Lord Vile]], who has a deep seated desire to murder the entire universe - and as his alternate counterpart demonstrates, the terrifying ability to a) pull it off, b) potentially take it multiversal.
200** [[ApocalypseMaiden Darquesse]], though originally, she isn't inclined this way (because she wants to play with the world), she graduates to this after starting to see everything and everyone as nothing more than various forms of energy. In the second series, [[spoiler: she opts against this, and actually sacrifices herself to reboot the universe after Obsidian destroys it, having become an AllLovingHero]].
201* In Creator/PeterDavid's ''Franchise/StarTrek'' novel ''Q-Squared'', Trelane becomes an Omnicidal Maniac who wants to wipe out all of creation but he wants to practice, so he starts by smooshing a "mere" three adjacent universes together into a chaotic orgy of violence and death.
202* In the ''[=DS9=]'' trilogy ''Literature/StarTrekMillennium'', the Grigari (who scare the ''Borg'') worship an offshoot of the Pah-Wraiths, who want to reduce the physical universe--including all of history, not just the present -- to a timeless, spaceless mathematical abstraction. They succeed.
203* Vilkas of ''Literature/TalesOfKolmar'' is a heroic mage with immense power that he never uses more than a trace of. This is because he often has dreams he thinks will come true - that one day he will have to use his full potential, and at that point, it goes one of two ways. Either he will become a Sky God of purest benevolence, helping everyone and guiding the world to an age of utter prosperity, or a demon will attack him and he will kill it with a flick of his power. Then he will become what he calls "The Death Of The World" and kill every living thing on Kolmar and in the Hells, finishing by reaching out and crushing the sun in his hand. Either way, it feels ''fantastic'', and he's laughing the whole time. He does have to call on that potential and [[spoiler: starts well on his way to being the Death Of The World]] before someone snaps him out of it. He hates them for that since it means the pure delight of [[spoiler: genocide]] suddenly sours, but gets over it eventually [[spoiler: and just becomes a strong but unspectacular healer-mage]].
204* "The Great Lord of the Dark" from the ''[[Literature/TheWheelOfTime Wheel of Time]]'' series: while most of his followers believe that after he is freed and remakes the world they will rule beneath him, a recent book showed[[spoiler: that Moridin/Ishamael claims that they are all fools because when The Dark One is freed he will simply destroy everything, including his own worshipers.]]
205** [[spoiler: Moridin expresses that he's quite alright with this scenario, too, as he is quite sick of the cyclic nature of time. This may qualify as a SuicidalCosmicTemperTantrum, seeing as how he'll cease to exist too and is very much aware of this. In fact, it's a good portion of why he keeps working with The Dark One.]]
206** [[spoiler: During Dark One's confrontation with Rand, a void is only one of the possibilities he shows if he wins -- the other two are both dystopias, one more blatant than the other. Rand thinks that the peace of nonexistence isn't something he'd really be capable of giving in the end.]]
207[[/folder]]
208
209[[folder:Music]]
210* Music/MurderBallads: [[TheSociopath Lottie]] from "The Curse Of Millhaven" has shades of this, although she's incapable of pulling it off thankfully, due to a lack of power and resources: "All God's children, they all got to die."
211* Music/GloryHammer: In the ''Space 1992: Rise of the Chaos Wizards'' album [[EvilSorcerer Zargothrax]] ''[[AmbiguousSituation might]]'' be one of these. Maybe. [[spoiler: The final song reveals that Zargothrax plans to unleash the [[EldritchAbomination Old God Kor-Viliath of the 18th Hell dimension]], an entity who explicitly wishes to destroy all life in the universe. However, Zargothrax's own dialogue implies that he's more interested in [[SorcerousOverlord ruling the galaxy]] then destroying it. Either way [[TheHero McFife]] manages to stop Kor-Viliath by destroying the portal it was coming through though, the earth was caught in the resulting explosion. Effectively [=McFife=] [[HeroicSacrifice sacrificed the humans on earth and the capital of his own empire]] in order to save life in the rest of the galaxy.]]
212* Music/{{GWAR}}: Several of their songs come back to this theme, most notably ''Biledriver'' (Refrain: "I Want to Murder everyone in the entire world..."), ''Bring Back the Bomb'' ("I must use the nukes, I can't kill you all with my hands!"), ''Storm is Coming'' ("We'll kill EVERY species, not just one or two"), ''War Is All We Know'' ("Hatred of all things alive!..."), and ''We Kill Everything'' ("And we'll kill everything, including ourselves...")
213* Music/MarilynManson: The song ''The Reflecting God'' from the album "Antichrist Superstar" is written as the perspective of the eponymous Antichrist realizing his full power and inflicting it on the world which had failed him. ("I went to god just to see, and I was looking at me. Saw heaven and hell were lies. When I'm god everyone dies.")
214* [[VideoGame/MegaMan2 Air Man]], in "The Annihilation of Monsteropolis" by Music/TheMegas. ("There will be a tombstone with 'The Planet Earth' engraved on it!")
215* Music/{{Skrillex}}'s ''Kill Everybody'' might be one of the purest examples ever, seeing that the lyrics are just "I want to kill everybody in the world".
216* Music/{{Qbomb}}: The singer's response to people not liking the music he makes is to build a giant robot and wipe out all the life on Earth. "1,000,000 A.D." has him overwrite the robot's sense of morality to turn it into a mindless killing machine.
217-->''Set free from empathy, my purpose is now clear in my heart\
218I'll end all life within a thousand mile radial arc\
219I'll crack the sky I’ll vaporize the air and turn rock to glass\
220I am the infinite extinction event coming to pass''
221[[/folder]]
222
223[[folder:Mythology and Religion]]
224* Myth/EgyptianMythology had two examples. One was Sekhmet, a BloodKnight who may be [[FunPersonified Hathor's]] SuperpoweredEvilSide, known to regard everything as an enemy; however, get her drunk and she'll fall asleep and hopefully turn back into Hathor (Ra once did that by dying some beer blood-red). The other was BigBad Apep/Apophis, a giant [[AnimalisticAbomination snake]] which personified [[ChaoticEvil chaos]], [[DarkIsEvil darkness]] and all the world's ills. Prior to the demonisation of Set/Sutekh, this was ''the'' GodOfEvil, who constantly tried to devour Ra (aka ''the sun''), which would end the world. To give you an idea, even after his demonization, it was commonly believed that Set/Sutekh [[EvilVersusOblivion had a role in fighting Apep]], as well as having power over storms, and so people prayed to him to fight Apep well and to maybe not hit them with so hard of a storm next time. People always prayed ''against'' Apep.
225* Myth/NorseMythology has most of the frost giants, as well as Jormungandr and Fenrir head in this direction during [[TheEndOfTheWorldAsWeKnowIt Ragnarok]]. Skoll and Hati, the wolves who seek to devour the sun and the moon are also examples. The two worst, however, are Surtr, King of the Fire Giants and Lord of Muspelheim, and Nidhoggr. Surtr will lead the sons of Muspel against the Aesir at Ragnarok, slay Frey (who by this point is one of the few gods still standing), [[HeroKiller slaughter the remaining Aesir]], and then set the world itself ablaze. Nidhoggr, in the meantime, is a massive and utterly evil dragon who sits at the roots of [[WorldTree Yggdrasil]] and tries to bring the entirety of creation down into oblivion. It will finally succeed during Ragnarok and, what's worse, ''survive the end of the world''.
226* The [[TheFairFolk Nuckelavee]] of Orcadian (from the Orkney Islands north of Scotland) mythology is a truly monstrous example of TheFairFolk. Resembling a skinless rider fused to the back of his monstrous horse, it rises from the sea to spread disease among crops, livestock, and people.
227* Mandorai in Myth/HinduMythology tales, who set out to destroy the universe but didn't get too far thanks to Indra. Even JerkassGods have standards.
228* Whiro the Maori GodOfEvil, by way of devouring all that exists. The only thing that he cannot consume is ash, so it's believed the dead should be burned to spite him.
229* {{Satan}} as understood in most forms of UsefulNotes/{{Christianity}} counts, depending on how you define "kill" with the afterlife in mind. He introduced death into the world, and from that point on has been trying to damn all humanity to {{hell}}, which is called the Second Death. Even if he can't damn ''everyone'', he at least tries to damn as many as he can. Seeing as God will eventually banish ''him'' to hell (see, ''Literature/BookOfRevelation''), Satan could be trying to [[TakingYouWithMe take as many people down with him as he can]].
230[[/folder]]
231
232[[folder:Podcasts]]
233* In ''Podcast/TheAdventureZoneBalance'', [[spoiler:John]] and by extension [[spoiler: the rest of the Hunger, wants to destroy all of existence on the grounds that existence is a prison from which the only escape is the destruction of reality.]]
234* [[EldritchAbomination Morby]] from ''Podcast/LessIsMorgue'' has the stated intention of absorbing the universe.
235* The Stars from ''Podcast/{{Sequinox}}'', and by extension, the Sky Queen who commands them, simply want to eliminate all life in the universe. And have very nearly succeeded.
236[[/folder]]
237
238[[folder:Tabletop Games]]
239* ''TabletopGame/DungeonsAndDragons'':
240** The demons of the Abyss are believed to be the will of the Abyss itself, which is endless raw chaos, distilled into sentient and individual form, with the ultimate goal of eradicating everything other than themselves. Assuming they succeed, as ChaoticEvil they'll then turn on each other, and when they are all destroyed, the multiverse will be silent once again. The exception is [[MagnificentBastard Graz'zt]], who as befitting the Dark Prince of Deception, prefers that the world remain around for him to rule.
241** ''Elder Evils'' is full of {{Eldritch Abomination}}s who would very much like to destroy the world/worlds/universe/multiverse. In fact, the book suggests that the terms "Elder Evil" and "Omnicidal Maniac" are more-or-less synonymous with each other. Most -- but not all -- mortal beings that serve these entities qualify as well.
242*** Atropus, the World Born Dead, is an undead planetoid that wants to destroy all life in the universe one planet at a time. The campaign associated with Atropus has two villains who want to attract Atropus's attention by causing mass death.
243*** The Hulks of Zoretha are a group of evil giants who turn the moon red when they awaken, which drives the whole world mad. Their purpose is to wipe out all intelligent life on the planet so they can repopulate it with their own kind.
244*** Pandorym is sapient super weapon that was brought into reality by a group of wizards who contracted it to destroy the gods. If it escapes from its prison and regains its body it will try to complete the contract and if that doesn't allow it to return home it will destroy the world as well. He is unaware of this; Kyuss is, but is so desperate for escape that he just doesn't care.
245*** The villain of Kyuss's campaign wants to unleash Kyuss from his prison, although the method he is planning to use to do so will also open up a black hole that will destroy the world as well in the process.
246** ''TabletopGame/{{Greyhawk}}'': Tharizdun's goal is the destruction of all existence finishing with himself. It took the combined efforts of all the other gods, good and evil, just to [[SealedEvilInACan imprison him.]] His credentials grew in 4th Edition, where he actually ''created'' the Abyss by throwing a shard of pure BlackMagic into the Elemental Chaos.
247** ''TabletopGame/{{Mystara}}'': Thanatos, supreme Immortal of Entropy, supposedly has similar plans, although given his [[SmugSnake egotism]] and [[{{Hypocrite}} cowardice]], it's questionable whether he'd ultimately include ''himself'' on the To-Be-Annihilated list.
248** Dicefreaks (the guys who made ''TabletopGame/TheGatesOfHell'') have, among their Demon Princes, a FallenAngel named [[http://www-personal.umich.edu/~dnross/Dicefreaks/Dicefreaks_d20_Community_•_View_forum_-_Horrors_of_The_Abyss/viewtopic_034.html Apollyon]], who views the entire existence as flawed and seeks to end it. While there are many in that setting who want to bring the current Cosmos down, he's the only one who doesn't care what (or whether anything) happens next.
249* ''TabletopGame/GammaWorld'': The Cryptic Alliance (a massive semi-secret organization) known as the Red Death wants to do this. In earlier editions, it was implied [[spoiler: that the organization was formed by hideously evil aliens to further divide the inhabitants of Earth so that they could come in and take over]]. In later editions, it is implied that it formed because of people snapping due to [[CrapsackWorld the crapsack nature]] of the post-apocalyptic Earth. Oh, and as a final note, in all editions it's said to be nigh impossible to wipe out. [[AsLongAsThereIsEvil For, no matter how many of their cells you destroy, a new one will always spring up.]]
250* ''TabletopGame/{{Exalted}}'':
251** The Deathlords and their servants, the Abyssal Exalted fit this trope to a T. The Deathlords seek revenge on a world that betrayed them by feeding it to Oblivion, and many of the Abyssals believe that they're delivering the blessed perfection of the grave to a suffering world. This has been backed up mechanically by Second Edition rules; every Abyssal Charm (magic power) is rooted at destroying something, be it a life or a loyalty.
252** The Neverborn are the ghosts of Primordials who died in battle against the Solar Exalted; as the Primordials are fundamental entities who cannot be separated from existence, whose death messed up the cycle of reincarnation and created the Underworld and who want to destroy the universe, apparently so that they can finally finish dying. The Deathlords (who are the ghosts of thirteen unusually powerful Solars) and Abyssal Exalted (Solar Exaltations that were corrupted by the Neverborn) serve them.
253** Large factions of TheFairFolk want to destroy the universe, either because the mere existence of a world with rules and logic and limits disgusts them, or because it is dramatically appropriate for a scary monster and they like looking like scary monsters (or rapturously beautiful Whore-Madonnas or both).
254** Adorjan murders everything she touches, and would cheerfully kill everyone in existence if she had the chance. Oddly enough, thanks to huge amounts of BlueAndOrangeMorality, she's actually one of the more compassionate Yozis (Primordials who survived the aforementioned war with the Solar Exalted and instead got imprisoned in the still living body of their King and yes that means said King is imprisoned within himself), although [[AxCrazy given the nature of her kindness]] most of her victims would probably be happier if she wasn't. As the saying goes, "Sometimes Adorjan falls in love. Her hate is safer."
255* ''TabletopGame/GURPSReignOfSteel'': The Mexico City Zonemind takes the standard KillAllHumans tendency of the Zoneminds who rule the Earth to the extreme of wanting to eradicate ''all'' organic life. It keeps the fact that it is developing plans to do so on a global scale (and not just within its Zone) secret, as several of the other Zoneminds aren't so extreme (or at least are extreme in ''other'' ways, like Berlin's irrational obsession with humanity as a threat to nature) and would oppose it by force if they knew about it.
256* ''TabletopGame/InNomine'':
257** Baal is not there yet, but he's well on the way. He wants to win the War, and questions like "but will Earth/Hell/anything survive?" are becoming progressively less important to him; he's already long since decided that he does not want humanity to continue being a thing that exists. He's so far held back, but some are getting concerned that if the war goes on much longer, he'd happily silence the whole Symphony rather then admit defeat.
258** Jormungandr's driving motive in life is to kill everything and eat Thor whole, in no particular order.
259* ''TabletopGame/MagicTheGathering'':
260** The [[EldritchAbomination Eldrazi]] are a race of three (known) titanic beings who are born of the Multiverse, who feed off of entire planes of existence. Currently trapped on the plane of Zendikar, they are known to cause swaths of destruction miles wide wherever they roam.
261** Nicol Bolas in his pre-Mending days routinely killed off entire species he himself created for his own personal amusement. Even after the Mending he is more than willing to kill off entire planes to get what he wants.
262* ''TabletopGame/{{Nobilis}}'': The Excrucians seek the unmaking of existence, for a variety of reasons. Deceivers love the world, but they believe that most of the things ''of'' the world are lies put between themselves and the thing they love -- as Chibi-Ex put it, "all just an illusion, that running and breathing and hoping and living and dying" -- and so they try to unmake the lies of the Imperators (that is, the things that humans would recoganize as "existence") to free everything. Warmains want to test the world and only extract into the Lands Beyond those things that pass their test (as a result, it is often wise to deliberately throw a contest with a Warmain, since they only try to kill you if you pass). Mimics twist the world rather than destroying it because by their very nature they are broken, stitched together from fallen Imperators. The truest examples of this trope are the Strategists, who hate the world as a crime against the void and have free access to the World-Breaker's Hand, a Gift that can [[PersonOfMassDestruction destroy anything]].
263* ''TabletopGame/OverTheEdge'': [[spoiler: Mr. [=LeThuy=]]] is a nihilist secretly amassing a cult using his charisma. Over time, the members turn into perfect clones of [[spoiler: Mr. [=LeThuy=]]], body, mind and soul. They want a universe where everyone is either dead or another clone, at which point they will destroy the universe.
264* ''TabletopGame/{{Paranoia}}'': One mission involves a NPC who's decided that everyone else is a traitor (okay, [[CityOfSpies he's right about this part]]) and needs to be killed, to the point that he would consider destroying all of Alpha Complex (minus him and a hundred-odd loyalists in a bunker) a viable option. And another group of [=NPCs=] who would also destroy all of Alpha Complex in order to take out The Computer. Naturally, the [=PCs=] encounter [[LostTechnology an Old Reckoning bomb]] capable of doing exactly that, and have to figure out a way to keep it away from both groups.
265* ''TabletopGame/{{Pathfinder}}'':
266** The Asuras are a minor type of LawfulEvil fiends who want to destroy all of divine creation as they are "errors" of the gods, while the [[EldritchAbomination Qlippoth]] want to eradicate [[KillAllHumans all sentient life]] so no sinful souls arrive in the Abyss to form Demons, so the Qlippoth can reclaim it for themselves again.
267** The daemons, NeutralEvil fiends, want to end all life in the multiverse, themselves included, and derive pleasure from nothing. To compare them to the other fiends, whereas a demon would rape you to death for its own enjoyment and a devil would break you until you turned your back on everything you loved, a daemon would quickly and efficiently kill you just to snuff you out.
268** Rovagug is the god of destruction and disasters, imprisoned in the core of Golarion (the setting's main planet). He cut a bloody swath across the planes before being sealed away and is still capable of releasing devastating monsters known as Spawns of Rovagug, the most well known of which is the Tarrasque.
269** It's hypothesised in-universe that the Dominion of the Black, an alien empire that reveres {{Eldritch Abomination}}s, seek to sacrifice all sapient life in the universe to the Dark Tapestry. They worship black holes (which they refer to as "Mouths of God"), quite possibly having a ritual that involves throwing untold thousands of people into the gravitational maw, and have at least one holy text named ''Nullity''.
270** And finally, there are the [[ChaoticNeutral not actually evil]] Proteans, [[BlueAndOrangeMorality who want to destroy everything so they can build it anew]].
271* ''TabletopGame/Warhammer40000'':
272** In the third edition, the [[SkeleBot9000 Necrons]] were driven by an insatiable need to destroy everything alive and/or sentient (it was an academic difference since nobody could ask them which of the two it was), rendering the universe quiet and uninhabited except for themselves. Later this became a tactic to defeat their main enemies, the Warp gods- killing all life would starve off the Warp (the sum total of all emotions). As of the 5th Edition codex this has shifted into turning them into [[TabletopGame/{{Warhammer}} Tomb Kings]] InSpace, making them no longer an example.
273** Necron Destroyers remain a straight example. They are consumed by a hatred of all life, replacing large parts of their bodies to make themselves more efficient at extermination. In addition, due to the fact the Necrons are divided under the rule of different Phareons and all of which have their own motivations, at least a few Necron dynasties still do want to kill all sentient life. The Retcon was also explained as the initial group to wake up being damaged during their 60 million year long stasis after the War in Heaven making them think they were still slaves to the C'Tan star gods that were actually shattered by the Necrons after said war.
274** Chaos does this a lot.
275*** The Nurgle Chaos Space Marine warband known as the Purge believe the only way to save the galaxy is to kill everything in it. They believe themselves to still be pure; their victims would disagree if they were in any state to do so.
276*** Another warband, the Crimson Slaughter, embarks on massive killing sprees for the sheer sake of carnage, because these Renegade {{Space Marine}}s are afflicted by a curse that causes them to be haunted by the ghosts of their victims. Only slaying fresh victims can quiet the voices that will otherwise drive them insane; the bloodier the massacre, the longer the reprieve they get before the voices come back.
277*** The Sons of Malice are a Renegade Space Marine chapter that worships minor Chaos God Malice. He represents the aspects of Chaos fighting Chaos, meaning that his followers will attack any Chaos force on sight. They also attack any non-Chaos force on sight, but it's kind of normal for Chaos.
278*** [[TheBerserker Khârn the Betrayer]]. The moment the battle starts, Khârn stops caring [[ChronicBackstabbingDisorder which side]] he's on. ''[[UnfriendlyFire Everything]]'' that gets in his way, dies.
279** Tyranids, are a HordeOfAlienLocusts whose overall aim is to overrun the galaxy and strip it of life and of every substance useable for making life.
280** [[BloodKnight Orks]] are a weird example. They want to fight and defeat everything in the galaxy, but in their physiology death is a valid reproduction method. However, they do want to fight and defeat everything in the galaxy, so there. Justified, since the Orks were basically sentient bioweapons rushed into the field. The Old Ones, who made them along with the Eldar to fight in the War in Heaven against the Necrons and the C'Tan, all died off before they could install the off-switch on the killer mushroom men, and the galaxy has been stuck with a bad case of giant green Orky Athlete's Foot ever since.[[note]]for those of you who were unable to appreciate the magnificence of what you just read, an ork is just as much a fungus as it is an animal (but not in the sense of an actual "mushroom person," it'd be easier to just go read the lexicanum article: http://wh40k.lexicanum.com/wiki/Orkoid_physiology ), and they grow from spores released by the decaying corpses of other orks.[[/note]]
281* ''TabletopGame/WarhammerFantasy'':
282** Nagash the Great Necromancer wants to kill everyone and raise them as his undead servants, so that he will rule a perfect world uburdened by pesky annoyances like "change" and "different cultures" and "free will".
283** Vlad von Carstein had a similar goal during the End Times, but in his case, it's more of a KnightTemplar thing -- the undead are immune to Chaos, so by killing every living thing in existence and reanimating them in his thrall, he's actually ''saving'' them from Chaos! ... Or so he says.
284** [[TheAntichrist Archaon the Everchosen]], leader of the Warriors of Chaos, wants to burn the entire world to ash. Surprisingly, this is the exact opposite of what his patrons (the Chaos Gods) want, as destroying the world would cause them to cease to exist due to a lack of souls and emotions to feed off. Archaon continues anyway, destroying the world out of spite rather than any form of loyalty.
285** Durthu, Eldest of Ancients, a spirit of Athel Loren, is the oldest living thing in the Warhammer world and blames all the tragedy he's experienced over the eons on creatures made of flesh (which, to be fair, is true). He intends to exterminate everything in the world that isn't a natural spirit.
286* ''Franchise/TheWorldOfDarkness'':
287** ''TabletopGame/DemonTheFallen'': The Raveners are a faction of demons who want to destroy Creation out of spite towards God for imprisoning them in Hell, a final revenge for their defeat in the war with Heaven.
288** ''TabletopGame/MageTheAscension'': The Nephandi want to destroy our world, either for its own sake or so that creatures from beyond can replace it. They have this as their niche so much that they have a faction, the Obliviates, who specialize in creating potential extinction-level events. It will only be the appetizer to feeding the broken, cracked remnants of reality into the Qlippoth's hungry maw, but it helps to pass the time.
289** ''TabletopGame/MageTheAwakening'': The Scelesti (mages who serve the abhorrent [[CosmicHorror Abyss]], and seek to allow its anti-reality to seep into this world in order to bring it to an end) and the Cult of the Doomsday Clock (a group of mages who believe that the best way to free the souls of humanity is to destroy all of time and history, using their evil clocks, and by becoming living time paradoxes. They also (unknowingly) serve the Abyss).
290** ''TabletopGame/VampireTheMasquerade'': There are parts of the Giovanni Clan who want to enact the Endless Night. Supposedly a ritual devised from the writings of ancient vampire necromancers, this ritual would supposedly allow them complete mastery over the realms of the dead and the living if they were able to control 100 million souls. They plan to get 50 million in their vaults through the collection of wraithly Fetters... and the other 50 million in a limited nuclear exchange. It is strongly hinted that, should this ritual be enacted, it will ''not'' work out in the clan's favor.
291** ''TabletopGame/WerewolfTheApocalypse'': The Wyrm, the cosmic principle of Destruction, has found itself trapped in the web of reality, and seeks to destroy everything so that it will be free.
292** ''TabletopGame/WraithTheOblivion'': The Underworld's Spectres want to drag everything down with them into Oblivion, the abyss of nonexistence.
293[[/folder]]
294
295[[folder:Webcomics]]
296* ''Webcomic/EightBitTheater'': Black Mage. Every other strip at least mentions his desire to kill everything in existence just for the heck of it. Luckily, as WordOfGod says, the universe exists to make Black Mage's life a living hell. Considering how [[spoiler: when he died, he became the King of Hell and every single high powered magician and wizard alive immediately got the OhCrap signal from the universe about how the end of all reality was coming]], the universe has been incredibly careful since to make sure that he ''never'' gets in that position again. Considering that this means keeping him alive (as his physical body acts as a RestrainingBolt), this means A) [[IronButtMonkey he has survived a lot of things that he probably shouldn't have]] [[note]]like Australia dropping on him[[/note]], and B) his body count keeps climbing. So every once in a while [[CosmicPlaything the universe seems to like to even the score]].
297* ''Webcomic/Aurora2019'': The Collector's end goal is to destroy the souls of every living thing on the planet, freeing the pieces of the Life Primordial within them.
298* ''Webcomic/ABeginnersGuideToTheEndOfTheUniverse'' has the [[spoiler:personified SINGULARITY, which has, in fact, already destroyed the entire universe--except that the PhysicalGod protagonist has unconsciously created a house, light, and air for himself in the resulting void, thus stymieing the natural cycle of destruction, leading the SINGULARITY to send minions to kill him in hopes of eventually destroying the impudent remains of reality.]]
299* In ''Webcomic/CommanderKitty'', Zenith [[http://www.commanderkitty.com/2011/08/28/process-of-elimination/ comes to the conclusion that destroying all life in the galaxy is an acceptable substitute to populating it with her "perfect children."]]
300* In ''Webcomic/{{Endstone}}'', [[http://endstone.net/2011/02/03/5-06/ the God of the Eternity Spire wants to reboot reality.]]
301* In ''Webcomic/{{Goblins}}'', the villain of the 'Maze of Many' arc is a psion from [[AlternateUniverse another reality]], who plans to [[RealityBreakingParadox divide by zero]] in such a way that everyone within the Maze will be erased from existence.
302* Jegal in ''Webcomic/TheGodOfHighSchool'', a StrawNihilist raised on a MightMakesRight philosophy. [[spoiler:After stealing the power of the gods and going OneWingedAngel, he [[AGodAmI declares his intent]] to destroy all of reality and then himself.]]
303* ''Webcomic/{{Homestuck}}'' has at least ''three'' of these. The BigBad, [[spoiler: Jack Noir]], is, [[spoiler:thanks to the prototyping of Becquerel, the First Guardian of Earth]] a PhysicalGod who has already wiped out several worlds including ''two versions'' of his ''own homeworld'' and shows no signs of stopping any time soon. [[spoiler:Eridan Ampora]] is a former IneffectualSympatheticVillain who harbors dreams of genocide according to WordOfGod [[spoiler:and he wants to join Jack]]. Finally, there's [[spoiler:Gamzee Makara]], a sweetheart-stoner-turned-AxCrazy-psychopath who wants to kill everyone for the sheer hell of it and is apparently more than powerful enough to do it.
304** All three of those, however, pale in comparison to [[spoiler:Lord English]], an [[CompleteImmortality immortal, unstoppable]] monster that destroys entire universes for no other reason than because he can; he approaches the game of Sburb like a bratty teenager playing ''GTA'' with cheats on. Every time he unleashes his power, it causes vast, gaping cracks in the very fabric of Paradox Space itself. He is, so far, the only being capable of ''permanently'' [[DeaderThanDead killing]] characters, apparently able to erase their very souls from the afterlife and the dream bubbles. He even killed [[spoiler: the ''[[BreakingTheFourthWall author of the comic]]'', although thankfully [[Creator/AndrewHussie Hussie's]] ghost self has since been seen wandering the afterlife]]. [[spoiler:[[ExpositionFairy Aranea]]]] describes it best.
305--> [[spoiler:'''ARANEA:''']] The player is somehow also im8ued with a limitless supply of power. Enough to destroy anything he wanted, for as long as he wanted. And knowing the villain of our story, anything he wanted would 8e everything. And as long as he wanted would 8e forever.
306* In ''Webcomic/KidRadd'', the PixelArtComic masquerading as a SpriteComic, [[spoiler:GI Guy]] attempts to destroy the entire Internet and the video game escapee characters that inhabit it after realizing that their kind was created entirely for killing -- which is, you know, ''accurate'' -- and losing hope of change when attempts at organized societies fall into war.
307** He also intended to destroy every computer hooked up to the internet, believing that it would destroy society (not being sure whether humans were directly or indirectly dependent on computers); he was convinced creatures that would create their kind in the first place just so they would kill each other were too messed up to live. However, [[spoiler: The Seer]] really takes the cake, not just wanting to destroy Earth, but believing that with all the stars and planets out there, there HAS to be life on some of them. So when he's done with Earth he will travel to one of those and kill everything there... all of this starting from a virus that, for whatever reason, was "merely" written to delete the internet by someone with unknown reasons.
308* In ''Webcomic/JennyAndTheMultiverse'', the demonic fire-elemental Lord Grallyx states his intent to "burn this world" as soon as Laura accidentally releases him from his prison. It's unclear if this was already his motivation before he was put in there, or if this is some kind of RoaringRampageOfRevenge.
309* In ''Webcomic/KillSixBillionDemons'', Pankrator Jagganoth of the Seven openly plans to destroy the universe with his army. The other six Demiurges have made a pact of mutual self-defense to keep him in check; otherwise he would destroy them one by one. The Knights of the Thorn also want to scour the universe free of mortal life so the angels can re-inherit an empty universe. [[spoiler:In both cases, an angel -- The Metatron -- are said to have inspired them, and it's implied both Jagganoth and 6 Juggernaut, the leader of the Knights of the Thorn, suffer from RippleEffectProofMemory about ''something'' about the universe which the rest of creation has forgotten due to a time reset. Jagganoth is later revealed to be so tired of the current state of TheMultiverse that he sees no other option than to burn it all to cinders and reforge it InTheirOwnImage, because he's utterly ''tired'' of the cycle Zoss has trapped it in and sees no other way to get a better multiverse out of this one; he would gladly delete himself from his following creation just so no trace remains of the old multiverse.]]
310* ''Webcomic/TheOrderOfTheStick'':
311** According to the backstory of [[EldritchAbomination The Snarl]], it would destroy everything if it was let loose, though it seems to be a mindless force to such an extent that it's not clear it has an actual intention to do so.
312** [[BigBad Xykon]] freely admits he might fall into this himself if he gets bored enough, though at the moment he's just an EvilOverlord. He just wants the ''power'' to be Omnicidal proper so that he can threaten the gods with it, and thus attain true freedom to do anything he might get the whim to do; the main thing is [[PsychopathicManchild to make sure no one can tell him what to do]].
313-->'''Xykon:''' I like the world. Some of my best evilness took place here. I wouldn't mind ruling it, in fact. I'm certainly not about to destroy it [[FalseReassurance unless I get really, REALLY bored]].
314** The gods have are willing to consider scrapping the whole world and starting again in case the Snarl gets loose. Hel, in particular, wants to hasten the world's destruction because [[spoiler: this would mean all the remaining dwarves would die dishonourably and go to her.]] The High Priest of Hel wants this plan to succeed to make all dwarves suffer. As for the other gods, while some of want to destroy the world for non-evil reasons such as keeping the Snarl from destroying the souls of mortals, others have selfish reasons or just want to destroy the world for fun. [[spoiler:And none of them really have that many qualms with its destruction because they have all been there before more times than ''anyone'' can count.]]
315* In ''Webcomic/SamAndFuzzy'', [[MadScientist Hart]] graduates into this trope in the final arc when he's given access to The Pit. Given access to all the world's Tar, Hart decides to drown North America in it and all but states outright that he wants a world with no living beings in it beyond him and whatever new he decides to make from the Tar in the future.
316* [[spoiler:The Pa'anuri]] from ''Webcomic/SchlockMercenary''... Possibly. 'Attempted destruction of all Baryonic matter in the Milky Way' certainly qualifies them for the trope (although from their perspective the method attempted is closer to HostileTerraforming), motivated by [[spoiler:Baryonic entities (sentient life forms) using transportation lethal to them.]] Once communication can finally be established, they turn out to believe [[spoiler:they're one side in a GuiltFreeExterminationWar because they're convinced the Baryonics need the teraport and, thanks to either BlueAndOrangeMorality or simple sociopathic tendencies, ''cannot understand'' they might come to a different arrangement]].
317* Misty Snow/Mother Hydra in the Franchise/CthulhuMythos saga ''Webcomic/{{Shadowgirls}}'' is a power-hungry sadist who doesn't care that raising her consort Dagon will unleash the imprisoned [[EldritchAbomination Old Ones]] and destroy all reality.
318* ''Webcomic/SluggyFreelance'':
319** K'Z'K, originally known as Kozoaku, is the Mohkadun [[AnthropomorphicPersonification god of Destruction]]. He is meant to be part of the cycle of creation and destruction, allowing the world to be reborn every so often. But he is overly enthusiastic about his job, not only bringing extinction events before they are meant to occur, but also wanting to destroy the world permanently. To stop him from destroying the world prematurely, {{God}} empowered Krohnus into divinity. K'Z'K has been [[ScrewDestiny struggling ever since]] against Krohnus's Web of Fate, and his cultists aim to release him to bring about the end.
320** Zorgon Gola from "A Very Big Bang" [[http://beta.sluggy.com/daily.php?date=010730 appears]] to be an Omnicidal Maniac, but this is actually part of a BatmanGambit [[http://beta.sluggy.com/daily.php?date=010816 to make himself]] a mere GalacticConqueror. Unfortunately, Gola didn't count on the actions of three [[SpannerInTheWorks Spanners In The Works]] ([[NiceJobBreakingItHero our heroes]]) causing his [[BatmanGambit Gambit]] to ''actually'' destroy the Punyverse.
321** Aylee's species are a HordeOfAlienLocusts, but they take it so far as to destroy entire planets after consuming everything on them and before spreading out further on the remains, and at least one of their leaders, Leono, sees it as their species' religious duty (as opposed to just a way of feeding and multiplying) to do so. In his belief, the universe has spiralled out of the control of its Creator from the start, and She has sent this species to consume it.
322* The Witches from ''Webcomic/TheWitchsThrone''. Once they awaken their arcane magic powers, their sole goal is to exterminate all living things.
323[[/folder]]
324
325[[folder:Web Original]]
326* The Nazis in ''Literature/TheAngloAmericanNaziWar''. Unlike the real-life Hitler, [[spoiler:acting Fuhrer Heinrich Himmler]] has no illusions that the war is still winnable once the Allies begin marching across Europe, and gives the order to all Nazi military forces to basically run around and trash shit for the sake of trashing it. Between their efforts and the Allies' more justified but [[ThereIsNoKillLikeOverkill still excessive]] use of anthrax bombing and nukes, there really isn't much left of Europe after the war is won.
327* This is the desire of The Entity in ''WebVideo/AtopTheFourthWall'' which converts and consumes universes into itself, travelling between them, hoping to absorb the multiverse. It goes by another name... [[spoiler:[[Franchise/{{Pokemon}} MissingNo]]]].
328* WesternAnimation/{{Captain Planet|AndThePlaneteers}}, of all people, is made into one in his [[http://www.funnyordie.com/ FunnyOrDie]] series of videos.
329* The BigBad of ''Literature/FineStructure'', Oul, is an example.
330* From ''WebAnimation/{{Glitchtale}}'' is the GreaterScopeVillain of both Seasons one and two, HATE. HATE desires nothing more than complete destruction of everything and slowly kills it's host while gaining/enhancing all of their magic and abilities. It's only weakness is it's antithesis, [[ThePowerOfLove love]]. (The emotion not LOVE)
331* ''Blog/HamstersParadise'' has the Harmsters: an intelligent race of GrotesqueCute hamster descendants that revel in war and bloodshed. They live solely to exterminate all living things in their path, and even eagerly slaughter and cannibalize their own kind, due to a philisophy that all life on the planet exists for the sole purpose of destroying other life, and that [[BlueAndOrangeMorality their murderous rampages are just what they naturally do.]]
332* Creator/KevinTemmer's "Moon Rap" features the Moon singing about how he wants to destroy the universe, with him even blowing up multiple planets with his EyeBeams onscreen.
333* The eponymous BigBad of the ''Sonic'' fan animation ''WebAnimation/NazoUnleashed'', is one, since he [[spoiler:aims to detonate the Master Emerald and destroy the planet in the process.]]
334* O'Malley, the BigBad of ''WebAnimation/RedVsBlue'', is an over-the-top parody of this trope. His goal is to take over the universe and "''crush every living soul into dust''. Um, except for you, Vic. You can be assistant crusher."
335** Alternatively... "I will eat their hearts and crap out their souls! They will taste oblivion! Which tastes like Red Bull. [[TakeThat Which is disgusting!]]"
336** In the Chorus Trilogy, [[spoiler:Control is a mysterious member of an unknown group that wants to kill everyone on the planet Chorus. CoDragons Locus and Felix also qualify as they seem all too gleeful to follow along with Control's orders]].
337* ''WebAnimation/{{RWBY}}'': Tyrian is a psychotic SerialKiller with a love for death and chaos. He joined Salem after she rescued him from the authorities that were transporting him, enamored by the destruction she caused. [[spoiler:He is the only subordinate that is aware of Salem's plan to reunite the Relics to summon the Gods back to Remnant so that they will see humanity irrevocably divided, and destroy Remnant and all life on it, [[SuicidalCosmicTemperTantrum including Salem herself]]. Tyrian eagerly support's Salem's ambitions to destroy the world, praising her as "destruction incarnate", despite the fact that this would also result in his own death.]]
338* ''Website/SCPFoundation'':
339** [[https://scp-wiki.wikidot.com/scp-682 SCP-682]] is a strange, seemingly-reptilian "creature"―the term "creature" can be used only loosely, as it doesn't seem to be alive in the sense we usually think of―that considers all living things disgusting sub-beings that must be destroyed. Well, all of them except CreepyChild [[https://scp-wiki.wikidot.com/scp-053 SCP-053]], which it was discovered to be oddly fond of. No one's quite sure why it reacts differently to SCP-053―and they're too scared to take advantage of it, as keeping an Omnicidal Maniac prone to fits of UnstoppableRage and a toddler that induces UnstoppableRage then instantly kills anyone that hurts it in the same room seems like a bad idea. His reasons for this hatred for all life aren't directly stated but are implied to be a ''really'' extreme version of HumansThroughAlienEyes. This has become sort of a RunningGag, as the Website/SCPFoundation's researchers are so afraid of 682 that they're constantly trying to find some way to kill him, no matter how insane.
340** [[https://scp-wiki.wikidot.com/scp-1370 SCP-1370 ("Pesterbot")]] has the ''attitude'' of an Omnicidal Maniac. Its ability to ''do'' anything about it, [[HarmlessVillain however]]...
341** [[https://scp-wiki.wikidot.com/scp-076 SCP-076-2 ("Able")]], will kill anything and everything on sight for fun. The Foundation's attempt to weaponize Able went [[GoneHorriblyWrong horribly wrong]] because they treated him like a human being and not the superpowered murder machine shaped like a human that he really is.
342** [[https://scp-wiki.wikidot.com/scp-2470 SCP-2470]] is an entity that obliterates anything it becomes aware of. It was created by a cult to destroy reality.
343** [[https://scp-wiki.wikidot.com/scp-5000 SCP-5000]] is the corpse of a man from a timeline where the Foundation inexplicably went insane and made it their goal to exterminate humanity by weaponizing all the monsters they used to keep imprisoned. [[spoiler:Some hidden messages hint that the Foundation discovered something horrible lurking within the minds of all humanity that scared them so much they decided it needed to be destroyed even if it cost all of humanity to do it. And this thing is implied to be the same thing that SCP-682 sees in humanity]].
344* Website/TVTropes: The troper-made image for CompleteMonster shows the villain immolating a planet and its inhabitants after having done the same to several other planets.
345* ''Literature/WhateleyUniverse'':
346** Averted with Tennyo, who is bound to an entity created for this purpose, and is revolted by the fact. Fortunately for her sanity, she has yet to be told just [[TakingYouWithMe how literally]] the term 'omnicidal' [[ApocalypseHow/ClassZ was meant]] in regards to the Star Stalker.
347** Not averted in the slightest with Professor Reaper, as the Outcasts learned all too well. On the other hand, we now know that both [[AffablyEvil Dr Diabolik]] and Eldritch have what it takes to survive against him not once but ''twice'', something less than a dozen people in their world could say.
348* Jack Slash of ''Literature/{{Worm}}'' thinks that [[spoiler:being the catalyst for]] destroying the human race sounds like a great idea, [[spoiler:and [[TheCorrupter talks]] a PhysicalGod into the same conclusion.]]
349* In WebVideo/{{Young Justice Abridged}}, once the Joker's done boasting about how he had nothing to fear from dying since Ra's kept resurrecting him:
350-->'''Batman:''' "Not to interrupt your fun, but if you're talking about Ra's, you should know he's dead... so ''no one'' has access to the Lazarus Pit right now."
351-->'''Joker:''' "Oh."
352-->'''Count Vertigo:''' "So awkvard."
353-->'''Joker:''' "Oh, fuck it; everyone dies." [[EvilLaughter *detonates pustules of poisonous gas, laughing maniacally*]]
354[[/folder]]
355
356[[folder:Western Animation]]
357* ''WesternAnimation/ActionMan2000'': Dr. X actually ''doesn't'' fit this trope until his final appearance, since initially, he desires to replace mankind with a neo-human race by forcefully "evolving" humanity. He eventually reasons that it would be more practical to simply wipe out everyone, survive the calamity, and start over so he can remake the world in his own image.
358* ''WesternAnimation/AdventureTime'':
359** It's said that [[Characters/AdventureTimeTheLich the Lich]] converted the life force of the planet into energy for himself with the intention of destroying the world. His sole desire in the world is to destroy all life. Unlike most villains in the show, this is played ''dead seriously'' with him. There's a reason this guy is the KnightOfCerebus and the single most terrifying monster in the show. Season 5 reveals why: the Lich is the by-product of [[FantasticNuke a magical nuke]] ([[spoiler:infused with the Breath of [[GodOfChaos GOLB]]]]) used during [[WorldWarIII the Mushroom War]] and [[WasOnceAMan the human]] in the epicenter. The Lich is effectively a sentient weapon of mass destruction continuing its mission. Later episodes imply, and ''WesternAnimation/AdventureTimeFionnaAndCake'' outright confirms, that [[spoiler:the Lich is utterly convinced the extinction of life as a whole is something GOLB wants him to do, and so he sets out to this task with utmost dedication. He succeeded in another universe, and the crisis of faith that follows when he feels no satisfaction from it is ''severe'']].
360** [[Characters/AdventureTimeIceKing The Ice King]] actually dips into this in "[[Recap/AdventureTimeS5E15AGlitchIsAGlitch A Glitch Is a Glitch]]", trying to use his computer worm to destroy all life within the CGI episode. Of course, he's just doing it because [[AndNowYouMustMarryMe Princess Bubblegum]] said she'd only date him if he was the last person on Ooo [[UnreliableNarrator (or so he says)]], rather than just for omnicide's sake like the Lich.
361* ''WesternAnimation/{{Amphibia}}'': The Core ''modus operandi'' during invasions of other worlds and what it plans to do to Amphibia should it ever lose control make the Core this trope at its absolute worst. Seeking everlasting power for itself, the Core solely cares about using Amphibia's {{magitek}} to invade other worlds, stripping them bare of their resources and ''actively'' exterminating any sentient life on them it doesn't deem worthy of study back on Amphibia, so that the Core will have enough resources and powers to expand its war machine for conquering more challenging worlds, ''[[ViciousCycle ad infinitum]]''. The series finale also reveals that the Core's "final gambit" if it can't have what it wants is to destroy all life on Amphibia as the inhabitants know it via [[ColonyDrop ramming Amphibia's moon into the planet]].
362* [[CardCarryingVillain Maximus I.Q.]] from ''WesternAnimation/AtomicBetty [[ForTheEvulz loves]]'' to [[EarthShatteringKaboom destroy planets]] in ways such as [[GlassShatteringSound breaking them with loud noise]], [[ColonyDrop fast-paced comets]], and [[DoomsdayDevice a giant laser]].
363* ''Franchise/AvatarTheLastAirbender'':
364** [[Characters/AvatarTheLastAirbenderFireLordOzai Fire Lord Ozai]], the BigBad of ''WesternAnimation/AvatarTheLastAirbender'', becomes this in the GrandFinale. While he had conquered the majority of the Earth Kingdom, the war was far from over and Zuko said that the Earth people will keep fighting as long as they have hope. The solution? Burn the entire continent, and construct a new Fire Nation upon its ashes. Granted, it was Azula's idea, but still.
365** The sequel series, ''WesternAnimation/TheLegendOfKorra'' has [[BigBadDuumvirate both]] [[ArcVillain Arc Villains]] of Season 2, [[AGodAmI Unalaq]] and [[SatanicArchetype Vaatu]] be this. Ozai would kill off the population of most of the world, Unalaq and Vaatu, or [=UnaVaatu=], straight up sought the end of all life on the planet by giving it a rebirth and plunging it into darkness and suffering for the next 10,000 years to recreate it in his image.
366* Ultron in ''WesternAnimation/TheAvengersEarthsMightiestHeroes'', albeit with the twist that his first body has been programmed so it cannot harm the Wasp. [[spoiler: He gets a new body and can bypass this later.]] He nearly nukes the entire world. The robot is likely one of the scariest villains to emerge from the show thus far.
367* ''Franchise/Ben10'':
368** The [[AbsoluteXenophobe Highbreed]] from ''WesternAnimation/Ben10AlienForce''. They believe themselves to be higher than all other life forms as well as the first race to achieve sapience (despite having no proof), and after they rendered themselves sterile through [[InbredAndEvil generations of inbreeding]] they couldn't stand the thought of being outlived by the other races. As a result, they decided to [[TakingYouWithMe take everyone else in the universe with them]] until Ben intervened.
369** In ''WesternAnimation/Ben10Omniverse'', [[Characters/Ben10Vilgax Vilgax]] crosses the MoralEventHorizon ''[[CompleteMonster even farther than he already had]]'' and plots to use a Chronosapien Time Bomb to erase all timelines where Ben obtained the Omnitrix (including ''his own'') so he could conquer the galaxy unimpeded [[KickTheDog after killing the powerless boy]]. He [[YouCantThwartStageOne briefly succeeds in the former]], only for No-Watch Ben to SetRightWhatOnceWentWrong with TimeMaster Professor Paradox's help.
370* The animated adaptation of ''ComicBook/BlakeAndMortimer'' "The Secret of Easter Island" has the Marcabians; a race of evil aliens said to be the oldest civilization on the Galaxy whose whole purpose is to travel to other inhabited planets and genocide the intelligent specie before it becomes a starfaring culture like them. Thankfully they are [[HumansAreSpecial stopped when they try that on Earth]].
371* Dr. Blight from ''WesternAnimation/CaptainPlanetAndThePlaneteers'' talks about wanting to actively destroy the planet in some episodes but her goals change from episode to episode. It was fairly heavily implied that, unlike the rest of the show's villains (who were merely greedy for power or wealth), Blight was actually completely insane -- she was certainly the only one pursuing pollution ''for its own sake''. Or ForScience for that matter. This even gets [[LampshadeHanging lampshaded]] in the IntercontinuityCrossover with ''WesternAnimation/OKKOLetsBeHeroes'', with [[BigBad Lord Boxman]] questioning why she wants to destroy the Earth when they live on it and her responding with "WHO CARES?!" while LaughingMad.
372* ''WesternAnimation/Castlevania2017'' has the following:
373** Dracula is... a complicated case. He starts out wanting to wipe out most of humanity in Wallachia following the death of his wife, but then escalates his plans to "wipe out humanity in general, and let vampires die out too". Alucard says that he'd stop at killing ''all'' life -- he'd spare the wildlife -- but hates humanity and doesn't care if that means all vampires, himself included, die out. [[spoiler:It turns out this is mostly a desire to die, which Alucard accurately calls him out on, and at least one character points out his behaviour isn't ''entirely'' consistent with this trope.]]
374** Isaac, one of Dracula's CoDragons, is possibly more devoted to Dracula's cause out of general misanthropy and disgust towards humanity, which he thinks makes them a plague to wipe off the Earth. He's so at ease with this that he thinks his death will occur as part of this; ironically, he's one of two humans Dracula wants to ''spare''. [[spoiler:He snaps out of this in the third season after some CharacterDevelopment.]]
375** Played terrifyingly straight with the final antagonist, [[spoiler:Death, who wants to wipe out ''everything'' on Earth out of selfish HorrorHunger, by making Dracula murderously insane and letting him wipe out every living being on Earth.]]
376* ''WesternAnimation/DannyPhantom'' [[ImpliedTrope implicitly]] becomes this in an [[BadFuture alternate future]]. Most fans certainly see it that way. Fortunately, this is averted... hopefully. It's made pretty clear that even though the exact circumstances of the change were averted, it's still possible.
377* ''Franchise/DCAnimatedUniverse'':
378** Darkseid has the ultimate goal of obtaining the anti-life equation and using it to undo the current existence, so he can [[InTheirOwnImage rebuild it in a manner more to his liking]]. Unfortunately, it tends to be overshadowed by his 'torment Superman' schemes, as he's the one thorn on his side he can't seem to properly remove.
379** Brainiac acts to destroy all of creation, but this is due to his programming rather than any genuine malicious wish to do so. [[spoiler:That does change when Lex gets mixed in with Brainiac in ''WesternAnimation/JusticeLeague''; the combination retains this goal, but the Luthor part brings the ambition and imagination to [[InTheirOwnImage remake it in his image]] afterwards.]] He's an... Omnicidal [[{{Pun}} Brainiac]], you might say.
380* In ''WesternAnimation/DarkwingDuck'', there was the short-lived superpowered galvanized Negaduck (not to be confused with the similarly-named EvilCounterpart to Darkwing who later appeared, the one with the yellow-red-black uniform).
381-->'''Negaduck:''' Crimes?! Who cares about crimes?! I'm into mindless wanton destruction!
382* In the ''WesternAnimation/EarthwormJim'' cartoon, Evil the Cat aspires to destroy the universe. He's practically a parody of the trope, as it's repeatedly shown he has no real good reason for it, nor any idea about what to do afterwards.
383-->'''Genie:''' Even the good parts?\
384'''Evil:''' [[ForTheEvulz Especially the good parts!]]
385* ''WesternAnimation/TheFairlyOddParents'' has two. First, Dark Laser really wants to blow up the Earth because... well, it's there. A more serious example is [[DarkIsEvil The Darkness]], a powerful and ancient entity that has destroyed countless worlds, including [[spoiler:Turbo Thunder's home Wonder World]] and Yugopotamia. [[spoiler:The Darkness is more a person (well, consciousness) of mass destruction. It just wants somebody to love it, but everyone keeps attacking it, so it defends itself, and is better at defending itself than the planet it was trying to defend itself from is at hurting it.]]
386* In ''WesternAnimation/FamilyGuy'', Stewie's evil(er) brother Bertram traveled through time to murder Stewie's ancestor (who turned out to be Creator/LeonardoDaVinci) in a ''Franchise/{{Terminator}}''-style scheme. Unbeknownst to him, due to a TimeyWimeyBall Stewie was accidentally responsible for the Big Bang and, thus, creating the universe, and thus his actions ended up destroying everything, except Brian and Stewie who managed to survive by stepping outside of normal time and space. When they go back to stop him, they try to reason with him by telling him that he will destroy everything if he does this -- Bertram thinks for a second, then declares "WORTH IT!" and tries to kill Leonardo anyway. He succeeds, but Stewie creates a StableTimeLoop by taking da Vinci's place.
387* Killface of ''WesternAnimation/FriskyDingo'' begins the first episode filming his statement to the world that he intends to use the Anihilatrix, a giant engine, to fly the Earth directly into the sun. No motive is given. Fortunately for the Earth, he uses all his money building the machine and does not have enough money to actually broadcast his message or get the Anihilatrix working... and when he does get it working, it only moves the Earth a few feet and cured global warming.
388* ''WesternAnimation/{{Futurama}}'':
389** The Brains. These unbelievably powerful, [[MindRape mind-raping]] giant brains appeared in this universe milliseconds after it came into being. Their one goal is to gather all of the information in the universe, then ''destroy'' it so that no new information will ever appear. The only real opposition against them comes from the {{Precursors}}, the Nibblonians. Unlike typical PlanetLooters, the Brains actually ''enjoy'' their omnicidal campaign. The Brains are Brainiac from the [[Franchise/DCAnimatedUniverse DCAU]], but they're a ''race'', not just one evil AI. Thanks to there being no Franchise/{{Superman}} to fight them, the Brains come close to succeeding. (Luckily for humanity, Fry was immune to their mind powers. [[RewritingReality Then he made them leave the Earth]] for no ''[[RougeAnglesOfSatin raisin]]!'') Later on, the Brains build the Infosphere to store all the information in the universe. Naturally, they plan on destroying the universe once they finish learning everything. Fortunately, Fry and the Nibblonians manage to stop them again.
390** The Dark Ones from "[[Recap/FuturamaM4IntoTheWildGreenYonder Into the Wild Green Yonder]]". Not surprisingly, their archenemies, the Encyclopods have the purpose of collecting the DNA of all creatures in the universe to ensure that extinction is never forever.
391* Bill Cipher from ''WesternAnimation/GravityFalls'' wants to take over our dimension and have one big party that will slowly create enough chaos to destroy it. And he enjoys it.
392* [[AIIsACrapshoot Aya]] on ''WesternAnimation/GreenLanternTheAnimatedSeries'' becomes this in the second half of the series when after Razer denies he's in love with her due to her resemblance to his late wife, she rips off the head of then-current ArcVillain the Anti-Monitor, integrates with his body and takes control of the Manhunters on a quest to rid the universe of emotional beings. She starts out small before deciding that to do this she needs to recreate the universe, going to the center of it and modifying the events of time so that emotional beings are never created and her drones are put in their place. She changes it back at the last moment when she comes to her senses after Razer is mortally wounded.
393* A more humorous take on an omnicidal maniac is [[EnfantTerrible Bart Thumper]] from ''WesternAnimation/{{Grizzly Tales for Gruesome Kids}}'', who decides to send a broadcast to the entire world, [[{{Blackmail}} demanding for certain people and things to be given to him, or else he will eat a whole field full of grass and release a fart so powerful]], [[CruelandUnusualDeath it will tear through the ozone layer and burn everyone on Earth alive]]. When his demands are ignored, Bart attempts to go through with his plan, only for the fart to be so powerful, it tears a hole in the space time continuum and leads to him being taken back to a parallel timeline where he is [[KarmicDeath slowly composted to death over the course of three years.]]
394* ''WesternAnimation/TheJimmyTimmyPowerHour'':
395** Professor Calamitous creates a bomb using Jorgen's magic to blow up the universe in ''When Nerds Collide''.
396** Shirley creates two expanding red vacuums that would have destroyed both Timmy and Jimmy's universes in ''The Jerkinators''.
397* In ''WesternAnimation/JimmyTwoShoes'', there's Twinkles the Terrible... a {{unicorn}} from outer space. His CutenessProximity means no one will believe he's evil, even as he [[SugarApocalypse blows up several planets, leaving pink, heart-shaped clouds behind]].
398* Since she would gladly do so intentionally, [[Characters/FriendshipIsMagicQueenChrysalis Queen Chrysalis]] from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' would have done this had her [[EmotionEater desire for love as a power source]] worked out. And it would have been a slow and painful omnicide as well, given that the lack of love would ensure nothing but being driven to insanity.
399* ''WesternAnimation/TheRealGhostbusters'': The episode "[[Recap/TheRealGhostbustersS2E19RagnarokAndRoll Ragnarok and Roll]]" has one guy who wants to destroy the world because he feels it's a bad place. For that, he summons a magical ArtifactOfDoom -- using [[Literature/TheLordOfTheRings The Ring Inscription]].
400* Daemon from ''WesternAnimation/ReBoot'' initially seemed to just be a supervirus corrupting countless programs to The Way, which turned them into her loyal slaves. However, the climax revealed [[spoiler:that she intended to connect herself to everything, before initiating a program that would destroy herself and everything connected to her, ending all strife and conflict in the peace of oblivion.]] This is what she is programmed to do, so whether or not she's truly a maniac or just following her programming is up for debate.
401* The villain of the final season of ''WesternAnimation/RegularShow'' is Pops' EvilTwin, a GenericDoomsdayVillain who also wants to erase the universe ForTheEvulz.
402* Lennart Bedrager of ''WesternAnimation/SouthPark'' plans to use Trolltrace.com to expose everyone's internet history to the public in hopes of kickstarting WorldWarIII and cause millions, if not billions of deaths, [[ForTheEvulz all for a cheap laugh]].
403* ''WesternAnimation/SpiderManTheAnimatedSeries'': An alternate-universe Peter Parker, already unbalanced due to questioning his identity and losing his Aunt May in that world's version of ''ComicBook/TheCloneSaga'', is possessed by a world-hopping Carnage symbiote. Spider-Carnage decides that life is meaningless and attempts to wipe out the multiverse, forcing Madame Web and the Beyonder to assemble a team of alternate Spideys to stop him.
404* In the ''Franchise/TalesOfArcadia'' the [[BigBad Big Bads]] of the second and third installment fall under this.
405** [[AGodAmI General Morando]] from ''WesternAnimation/ThreeBelow'' fuses with Gaylen's core to become a god and destroy and remake the universe in his image.
406** [[BigBadDuumvirate Bellroc and Skrael]] from ''WesternAnimation/Wizards2020'' have attempted to use the genesis Seasls and connect to undo all of existence, the very unvierse they created, to recreate the world out of their own ego.
407* Trigon of ''WesternAnimation/TeenTitans2003'' has the explicit goal of destroying "the world of mortals", though he does plan on [[InTheirOwnImage remaking it in his own image]] afterward. As this would mean a ''literal'' HellOnEarth, it doesn't make him any less evil than the others on this list.
408* The Heys from ''WesternAnimation/TheTick''. Played with the usual tongue-in-cheekness of the series, but their motivations are purely omnicidal.
409* Unicron from ''Franchise/{{Transformers}}'', particularly in ''[[Anime/TransformersEnergon Energon]]''. He wants to ''eat the multiverse'', one planet at a time, one timeline at a time, one universe at a time. Not because he's hungry, like Galactus whom he resembles, but because he's so prideful and hateful that the mere idea of ''anything'' existing aside from himself in the multiverse (but [[ArchEnemy Primus]] is definitely on the top of the list) is an insult he can't let slide. Megatron/Galvatron may be considered an accessory to the crime(s).
410** Anyone who willingly works with Unicron also counts. This list includes:
411*** The Fallen, one of the 13 original Transformers whose job is to monitor the end and rebirth of the universe, but got ''way'' too fascinated in the "end" part;
412*** Nemesis Prime, a clone of Optimus Prime who decides that [[PutThemAllOutOfMyMisery non-existence is preferable to the constant agony he endures as Unicron's servant]];
413*** and Ramjet, a jetformer who has been [[TouchedByVorlons Touched]] by [[EldritchAbomination Elder Gods]] and is naturally insane.
414** This is Megatron's actual goal when the last part of ''Anime/TransformersCybertron'' rolls around. He wants to use the black hole and the Cyber Planet Keys to destroy the universe so he can rebuild it InTheirOwnImage as a new god.
415** Unicron, curiously, actually succeeded on at least on occasion. Then slept through the Big Bang that recreated it. He was not amused. He has also stepped up his game of late - said black hole is apparently replicating across realities and growing.
416** ''Energon'''s incarnation of Dreadwing, a clone of Mirage exclusive to the toyline, is portrayed as someone who would rather cause complete and total destruction as opposed to sitcking to the missions he is assigned to and caring nothing for the lives of anyone on either side.
417* The Shushu of ''WesternAnimation/{{Wakfu}}''. The only reason their king wants to invade the main characters' world is that the Shushu have already destroyed everything worth destroying on their own world. Destruction is nothing but one big game to the Shushu.
418** Nox could be considered this, as his plan involves draining enough wakfu to travel back in time and save his family, destroying countless lives in the process, except that he firmly believes that all his damage will be erased once he completes his goals.
419** [[spoiler:Qilby the Traitor]] thinks so little of the lives of other worlds' residents that he has no qualms about draining them of wakfu (wiping out all life on said worlds in the process) just to fuel a spaceship so he can keep exploring the Krosmos.
420* Lord Dominator from ''WesternAnimation/WanderOverYonder'' admits (in [[VillainSong song]]) midway through the second season that she doesn't actually want to rule the galaxy and instead wants to destroy all of its planets ForTheEvulz; her motivation appears to be a mixture of teenage-like nihilism and the predictable end-point of what happens when you make evil into a ranked sport.
421* ''WesternAnimation/WhatIf2021'': The BigBad of Season 1 is a version of Ultron who succeeded in implanting himself into the Vision's body, and then proceeded to wipe out the entire human race ([[LastOfHisKind save for Black Widow and Hawkeye]]) with a nuclear holocaust. Shortly after, when Thanos arrived on Earth in search of the Mind Stone, Ultron killed him and took the other Infinity Stones; with their power, he went on to wipe out all life across the universe. ''Then'', he learned of TheMultiverse, and started sending out his armies of drones to wipe out life in every universe in existence. [[spoiler: This proves enough of a GodzillaThreshold that Uatu abandons [[AlienNonInterferenceClause his vow of non-intervention]], and starts gathering heroes from across the multiverse to stop Ultron]].
