%% That's plenty of quotes, please. Let's leave some room at the top for the article.

Who caused the EarthShatteringKaboom? ''This guy''. Destroying continents, wiping out civilizations, exterminating whole planets: When this character turns up, entire ''galaxies'' or ''universes'' may die, if not reality itself -- the OmnicidalManiac has made his entrance and where he goes, the survival rate of everything nearby quickly drops towards zero.

Put simply, the OmnicidalManiac is a villain who actively seeks the destruction of whatever world the setting is based in to the exclusion of everything else, and is both aware of what he's doing and fully motivated to do so. Most {{Omnicidal Maniac}}s will aim for a class 5 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, expect the whole galaxy or even the universe to be his goal. Nonetheless, the OmnicidalManiac will want it all destroyed. Despite the name, being completely insane is not actually a requirement, but having a FreudianExcuse doesn't make the OmnicidalManiac any less of a menace.

Contrast the PersonOfMassDestruction, who doesn't ''want'' to use their powers to destroy the world, the MikeNelsonDestroyerOfWorlds, who causes damage of this scale largely by accident, through ignorance, or for comedic, non-serious reasons intended to elicit laughter. {{Omnicidal Maniac}}s are ''not'' amusing and have clearly-defined reasons for wanting to destroy everything nearby, which they do with a great deal of malice. The OmnicidalManiac might overlap with the SuicidalCosmicTemperTantrum if his motive is to take the whole of existence with him, though this may also lead to the WoobieDestroyerOfWorlds, who is generally treated with some degree of sympathy because the reasons are less malice and more of a desire to end it all.

A step-up of KillAllHumans. Compare the PlanetEater, PlanetLooters and HordeOfAlienLocusts, which have similar outcomes but don't necessarily do it out of malice.

The NietzscheWannabe, the PsychoForHire or the AGodAmI mentality are very popular amongst this character archetype.

!!Examples:

[[foldercontrol]]

[[folder: Anime and Manga ]]

* Anyone of importance in ''{{Dragonball}}'' [[EarthShatteringKaboom can blow up planets]]. However, only Majin Buu seems intent on undoing all of creation merely out of malice, spite and boredom. And inability to get ice cream.
**Cell planned on becoming one of these after the Cell Games, but was killed before he could get started.
* Valgaav, both TheDragon and BigBad of ''[[TheSlayers Slayers TRY]]'' wanted the destruction of everything ''before'' merging with Darkstar, believing that oblivion was what the world deserved. Afterwards, the knowledge he gained about the nature of the universe drove him to become a WellIntentionedExtremist merged with Darkstar's godlike power, intending to destroy the entire world and then remake it without strife or conflict.
** In the novel canon, ''all'' Mazoku are [[NietzscheWannabe nihilistic]] Omnicidal Maniacs; in the anime this is most visible with Hellmaster Fibrizo:
---> '''Fibrizo:''' "I want to be destroyed. I want to be destroyed! Destruction? Yes... Destruction is the ultimate wish of any Monster. That's what we were created for. Isn't it? That's what we were created for! [..] But this destruction shall consume all things! It shall consume the entire world! [...] All the world! Let all the world be destroyed with me!"
** Subverted with Xelloss, who pays lip-service to the Mazoku "blow up everything" mentality but clearly enjoys life way too much for him to mean any of it. He attempts to excuse his saving the world from Duragnigdu by saying that destroying the world is his job, not Dark Star's. Riiiiight. We believe you.
*** At that time he wasn't acting for his own benefit, but working as the envoy of the entire Mazoku race, so presumably the surviving Mazoku Lords agreed on his logic there, as well. Plus that he was promised that the power released from the killed Dark Star would be granted to the local Dark Lord, Ruby-Eye Shabranigadu. It's left unclear whether that bargain was held or not, but if it was, then Xelloss definitely hastened the homemade Apocalypse by getting rid of the foreign product.
**** That deal about getting some of Dark Star's energy was never intended to be fulfilled, probably by both sides - nothing shows this more than the fact that Xelloss betrayed the Overworlders shortly after the deal even got mentioned.
* Rau Le Creuset of ''[[MobileSuitGundam Mobile Suit]] GundamSEED'' isn't perhaps the most obvious, as his goals merely encompass the extinction of humanity, Natural and Coordinator alike. However, given the much smaller scale(the action never extends past the Moon due to limited space travel), it's quite omnicidal in context.
*''{{Digimon}}'' seems to have at least one per season:
**''DigimonAdventure's'' got Apocalymon. The name says it all. When he was defeated, he tried to unleash a blast that would eradicate the human world and the Digital World.
**''DigimonAdventure02:'' BigBad ([[FakeBoss or so we think at the time]]) Arukenimon's main plan is to destroy the [[CosmicKeystone Cosmic Keystones]] that maintain the barriers between dimensions, which would cause all dimensions to collide, destroying the multiverse. Her intended [[TheDragon Dragon]] refuses to help on the grounds that she's an unworthy mistress, but eventually decides, for his own reasons, to do the same, making him just as much of an OmnicidalManiac.
**''DigimonTamers'' features a non-Digimon AI that was designed to prevent other programs from exceeding their boundaries ('cause AIIsACrapshoot) by deleting them if they surpassed a certain stage of development. It decides all humans and Digimon meet criteria for deletion. Then it gets ''[[EldritchAbomination really]]'' [[TheHeartless nasty]].
**''DigimonFrontier's'' Lucemon is more of a digital EvilutionaryBiologist. The data that makes up Digital World's matter (and population) is easily manipulated, and it ''all'' had to be absorbed and used to release him [[SealedEvilInACan from the Dark Area.]] He planned to use it to rebuild the world as he saw fit.
**''DigimonSavers'', aka ''Digimon Data Squad,'' has Yggdrasil/King Drasil, the computer that runs the Digital World. When the previous arc's BigBad's plan backfires and both worlds are going to collide, he decides that the human world must go. When the Digimon fight against him and his minions to protect it, guess what he ''then'' decides? He, too, plans on restarting the Digital World after destroying the old one.
* The [[BigBad Millennium Earl]] in ''D.Gray-Man'' is very open about this, explicitly taunting the hero in his first real appearance.
-->'''The Millennium Earl:''' "You have only witnessed the opening chapter... the akuma in this world will continue to evolve. Now begins the journey leading up to the true tragic end. I am the Millennium Earl, the maker of the akuma. I shall obliterate your puny "God" and lead the world to its death with my akuma. An exorcist, a soldier of life. You can't save this world no matter how hard you try."
* [[EnemyWithout The berserked defense program]] of the Book of Darkness in ''MagicalGirlLyricalNanoha''. Its existence is as thus: Appear when [[TomeOfEldritchLore Book of Darkness]] fills all [[NumberOfTheBeast 666 pages]], [[TheEndOfTheWorldAsWeKnowIt destroy every world and dimension in its path]], get temporarily killed either from a really powerful weapon or from having burned out its considerable amount of magic, [[BackFromTheDead rejuvenate with Book of Darkness somewhere else]], repeat.
*''SailorMoon'' has several, Wiseman/Death Phantom the BigBad of the R season, the entire Death Busters organization of the S season and Sailor Galaxia of the Stars season.
* Ralph Werec in ''SoukouNoStrain'' went back in time via SubspaceOrHyperspace and saw the [[PoweredByAForsakenChild cost]] of the research that went into the BlackBox that powered the series' HumongousMecha. His sanity didn't make it out intact, and he decides to destroy his entire race in retaliation, never mind that nobody knows anything about it.
* ''FutariWaPrettyCureSplashStar'' gives us [[spoiler: Gooyan, the NotSoHarmless ManBehindTheMan.]]
* ''AhMyGoddess'', of all series, had one. The Lord of Terror aka The Ultimate Destruction Program, a bodiless entity whose one goal is to destroy the universe and recreate it in its own twisted image. Given the highly idealistic nature of the series, it failed (though it was a close call) and was [[spoiler: KilledOffForReal when it was tricked into possessing a floppy disk which Skuld erased using a magnet]].
* In MahouSenseiNegima, the Mage of Beginnings and his minions, [[spoiler:the three incarnations of Averruncus]], want to destroy Magicus Mundus (a pocket dimension planet the size of and dimensionally anchored to [[spoiler:Mars]]). Played with a bit in that they seem to think this will "save the world".
** One character refers to [[spoiler:the third Averruncus]] as a religious nutjob, so it may be a "destroy the world so that it may be reborn" cult thingy.
** Ostian Governor-general Kurt Godel recently revealed that [[spoiler:he wants to wipe out anyone who's not a normal human. That means wiping out most of the magic world's population.]]
* Yami Malik of Yu-Gi-Oh explicitly states in the manga that all he wants is total destruction of everyone and everything.

[[/folder]]

[[folder: Comics ]]

* Imperiex of the {{DCU}}, a hive minded mechanical entity, saw its purpose as being the "hollowing" of the universe, destroying the flawed creation and remaking it in a new Big Bang. Ironically, [[spoiler: the flaw he detected in the universe was himself, and a massive cooperative effort managed to throw him into the past where he in fact became the Big Bang in the first place, via a StableTimeLoop]].
*DC Comics' [[CrisisCrossover ''Crisis'' crossovers]] has the following:
**''CrisisOnInfiniteEarths'': Anti-Monitor
**''Zero Hour'': Parallax (Hal Jordan, though the circumstances of it was changed during ''Green Lantern: Rebirth'') and Extant
**''InfiniteCrisis'': Alexander Luthor and Superboy-Prime
**''FinalCrisis'': [[NewGods Darkseid]] and Mandrakk
**''BlackestNight'': Nekron
* While he does not typically fall under this category, The Joker did, in fact, reach this state during the "Emperor Joker" plotline in the ''{{Superman}}'' comics. In fact, considering that plot and a number of other situations it could be argued that the only things preventing the Joker from permanently attaining this state are a lack of superpowers and his obsession with Batman.
* Thanos is the most famous MarvelComics example. He has a vision of [[TheGrimReaper Death]] as a beautiful woman and in order to win her favor he embarks on a quest to kill every living thing in the universe.
* Abraxas also hails from the MarvelUniverse. The antithesis of Eternity, it exists only to destroy anything and everything in all creation. Keeping it imprisoned is one of the reasons Galactus needs the life energy from devoured worlds. The one time Abraxas ''did'' break free it...wasn't pretty.
* Annihilus, also from the MarvelUniverse, became one of these during the "Annihilation" CrisisCrossover. His vast Harvester fleets carved a path of devastation across the galaxy, nearly wiped out the Kree and Skrull empires, and (with the help of Thanos and two cosmic superbeings) imprisoned ''Galactus himself''. Why is he an OmnicidalManiac instead of just another alien conqueror? Annihilus' true motivation for capturing Galactus was to [[spoiler: turn him into a ''bomb''. A bomb that would kill ''everything in the universe except for himself'']]. What's truly scary is that he came damn close to pulling it off too.
* Jenny Fractal of the Wildstorm universe. She is the twin sister of Jenny Quantum kidnapped at birth by the Chinese government. She was put in an assassin program where she was forced to watch humanity's evil deeds:rape,murder,genocide,etc...She has the power to fracture reality and wants to use planet earth as a blackhole center to implode and collapse the entire multiverse. She states her reasons for doing this claiming "it's the only way to save them".
* One of the four possible backstories for The Phantom Stranger given in his issue of "Secret Origins" features a mad scientist from the future who wants to time travel back to the Big Bang and prevent it from effectively occurring. So not only does he want to destroy the universe, he wants to make sure it *never even existed in the first place*.
* Doomsday, the monster whose sole claim to fame and reason for being written in the first place was to (almost) kill {{Superman}}, is a [[BoringInvincibleVillain pretty boring villain]]. What little characterization he was given comes from his backstory. A MadScientist on Krypton exposed the an infant to the hostile environs of the planet and let it die. Then he took the remains and somehow reincarnated the baby. This process was repeated again and again until Doomsday was the result. Having experienced death hundreds if not thousands of times, Doomsday sees ''everything'' as a threat and acts accordingly. By the time he reached Earth he had already destroyed multiple worlds. That part about the experiment taking place on Krypton also means that he hates things from Krypton such as Superman just a ''little'' bit more than everything else. Due to his mindlessness, Doomsday straddles the line between this trope and a non-comedic MikeNelsonDestroyerOfWorlds.

[[folder: Film ]]

* In ''{{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.
* Nero from ''[[StarTrekXI Star Trek]]'' is one, and then some. He doesn't want to wipe out the ''entire'' galaxy, just [[spoiler:everyone who isn't a Romulan, starting with Vulcan]].

[[/folder]]

[[folder: Literature ]]

* In Peter David's StarTrek novel ''Q-Squared'' , Trelane becomes an OmnicidalManiac 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. While [[MagnificentBastard playing the harpsichord.]]
* In the''StarTrek DS9'' trilogy ''Millennium'', 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. [[IGotBetter It gets undone anyway]].
* Michael Swanwick's two parallel novels ''The Iron Dragon's Daughter'' 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.
* In ''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.]]
* The titular machines of FredSaberhagen's ''Berserker'' series 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.
* The [[BigBad Storm King]] of TadWilliams' ''[[MemorySorrowAndThorn Memory, Sorrow and Thorn]]'' series hovers on the border between OmnicidalManiac 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 TheMessiah 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.
* Hactar, from ''[[HitchhikersGuide Life, The Universe, And Everything]]'', 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 superweapon 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.
* 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.
* [[NamesToRunAwayFromReallyFast Ruin]], BigBad of Brandon Sanderson's Mistborn Trilogy, is basically Omnicidal Mania incarnate. 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 its the literal god of destruction and is just doing its job, but still the thing seems incapable of recognizing that unchecked destruction is ''bad'' (or maybe it does recognize it, but because of what it is it is incapable of caring).
* The main villain of [[TheDarkTower The Dark Tower]] 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: Pretty much because he wants to, and he can.]]

[[/folder]]

[[folder: Live Action TV ]]

* Early ''PowerRangers'' villains were always talking about conquering or destroying the world, the same villain going from one to the other and back frequently. From season five onward, villains are more certain about what it is they're after.
* ''DoctorWho'' has plenty of these, with the trope perfected in Sutekh from "Pyramids of Mars", who wants to destroy all life in the universe.
-->'''Sutekh:''' I am Sutekh the Destroyer. Where I tread, I leave nothing but dust and darkness. I find that good.
** The Doctor Who New Series "perfected trope" can be found in Fourth Season episode "Journey's End", where Old Series villain [[spoiler: Davros]] has [[spoiler: taken Dalek xenophobia to its extreme by creating a "Reality Bomb" which will annihilate reality]].
---> [[spoiler:[[LargeHam This! Is my ultimate victory Doctor! THE DESTRUCTION! OF REALITY! ITSELF!]]]]
** In the old series, Davros never quite attempted this, but conversations between him and the Doctor suggested he would if he had the power - simply because he ''could''. [[spoiler: Which pretty much sums up why he'd want to destroy all of reality in Series 4 - because he can.]]
**And Fenric, don't forget him.
* Anubis in ''{{Stargate SG-1}}''. While ''all'' Goa'uld are AlwaysChaoticEvil, this guy stands out. He doesn't want to control the entire galaxy, he wants to ''wipe out all life'' in it. And then repopulate it with lifeforms of his design, but that's an academic distinction to anyone that's not Anubis.
* [[{{Buffy}} DarkWillow]].
* The Cylon Cavil in ''BattlestarGalactica'' is practically one of these. He's tried to kill off all of humanity (with over 90% success) and most of his own race, the exceptions being the Simon and Doral models (only because they sided with him, natch).
* The Bio-Vizier Mantrid in [[http://tvtropes.org/pmwiki/pmwiki.php/Main/Lexx Lexx]] went from a garden-variety psychopath to a complete nihilist who [[spoiler: managed to destroy the 'Light' universe of Lexx with his Drone Arms, which would obliterate a planet and use the materials to make new Drone Arms. Each 'generation' of planets destroyed effectively doubled the number of Drone Arms; one planet is destroyed, we have two batches of Drone Arms. These destroy two planets, and now we have four batches. These destroy four planets, etcetera. They were capable of travelling faster than light (considerably so), and he was eventually tricked (AFTER they had "consumed" the 'Light' universe) into bringing them too close together, where their collective gravity ended up collapsing into a 'Big Crunch', the opposite of a Big Bang.]] Many wished to destroy the universe, but before Mantrid, none succeeded. Of course, the so-called "Heroes" [[spoiler: escaped into our universe, the 'Dark' universe, before this happened.]]

[[folder:TabletopGames]]
* The Excrucians in ''{{Nobilis}}'', for reasons best known to themselves.
* The Deathlords and their servants, the Abyssal Exalted, from ''{{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.
** The Neverborn are the ghosts of 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.
** Large factions of TheFairFolk want to destroy the universe, either because the mere existence of a world with rules and Alogic limits and 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).
* The ''{{Warhammer 40000}}'' setting features the Necrons, who will strip planets clean of life out of their all-consuming hatred for the living and their C'tan masters who seek to destroy all souls in creation and feast on the life force of the living. There's also the forces of Chaos, who ultimately seek to overlap the physical reality with the Warp, home plane of the daemons, and thus turn all reality into hell on earth... Literally.
-->'''Necron Pariah:''' There is an alternative (to life). There exists a state in which all conflict is resolved and all is cold and silent. There are no wants, no wars, no squabbles. You may call this state death if you wish, but that is a misnomer. Death is but the ending of life, and that is only a means to an end. That end is purity, the time when all is still and unchanging.
** The fact these two are (im)mortal enemies is small comfort to those caught in the crossfire... That would be us.
* The demons of the Abyss from the ''DungeonsAndDragons'' settings. They are believed to be the will of the Abyss itself, which is of course 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'zat]], who as befitting the Dark Prince of Deception, prefers that the world remain around for him to rule.
** While in 3rd and earlier editions this might be an example of [[LawfulStupidChaoticStupid Chaotic Stupid]], in 4th it's their defining characteristic.
*** And then there's Tharizdun from the {{Greyhawk}} setting whose 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 {{Black Magic}} into the Elemental Chaos.
**The book Elder Evils is full of [[EldritchAbomination Eldritch Abominations]] who would very much like to destroy the world/worlds/universe/multiverse.
* In the new WorldOfDarkness, while many beings are malevolent and highly destructive, most noteworthy are 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).
**From the old [=WoD=], there's the Wyrm, the cosmic principle of Destruction, which has found itself trapped in the web of reality, and seeks to destroy everything so it will be free. Also of note are the Underworld's Spectres, who want to drag everything down with them into Oblivion. And the Mages have the Nephandi, who want to either destroy our world, period, or destroy our world so that creatures from beyond can replace it.

* ''TheLegendOfZelda: Majora's Mask'': Clearly, any demon [[SealedEvilInACan trapped inside a mask]] who wants to completely [[EndOfTheWorldAsWeKnowIt destroy the world]] by [[ColonyDrop crashing the moon into the earth]] can't be sane.
* ''FinalFantasy'' is big into this. In order:
** [[FinalFantasyI Chaos]], who came into existence thanks to the Fiends, who were already destroying the world to begin with.
** [[FinalFantasyIII Xande]] is pissed about being made mortal and wants to put everything into suspended animation, forever. [[spoiler:Cloud of Darkness, a personification of the Void]] wants to reduce everything in both worlds to nothingness.
** [[FinalFantasyIV Zemus]] wats to exterminate all human life on Earth so that he (and the other Lunarians, maybe) can rule. Zeromus is just evil. [[GiantSpaceFleaFromNowhere Or something]].
** [[FinalFantasyV Exdeath]] is an arbormorphic personification of evil. [[spoiler:Neo Exdeath, a personification of the Void]] wants to reduce everything (including itself) to nothing... [[FinalFantasyIII wait...]]
** [[FinalFantasyVI Kefka]], who is already quite insane but just got worse due to his acquired power from the Statues, wants to destroy reality and "build a monument to nonexistence."
** [[FinalFantasyVIII Ultimecia]] wants to compress time into a TimeyWimeyBall so she can recreate the entire universe because she's pissed off about centuries of oppression against her kind.
** [[FinalFantasyIX Kuja]] doesn't like the idea of the universe outliving him.
** [[FinalFantasyX Seymour]] thinks that life is nothing but suffering, and that the only way of escaping [[EldritchAbomination Sin]], the cause of it is that everyone should die.
** [[{{FinalFantasyX-2}} Shuyin]] was subjected to MindRape for a thousand years, so he really doesn't know why he's trying to kill the world, only that [[WoobieDestroyerOfWorlds it makes him feel better]].
** [[DissidiaFinalFantasy Chaos]] ([[FinalFantasyI again]]) chooses to destroy the world [[SuicidalCosmicTemperTantrum and himself]], after finding that a world [[spoiler: without Cosmos]] was a much emptier existence than he thought it would be.
* Id from [[XenoGears Xenogears]] wants to basically kill everyone and everything, for rather vague reasons. Granted, [[spoiler:he IS the embodiment of all hatred and suffering that Fei had mentally suppressed]], but it doesn't change the fact that he finds little reason behind his slaughter other than it being fun.
* The Destroyer from RomancingSaGa3
* Run, all ye Mortals, for [[GodOfWar Kratos]] approaches
* According to [[spoiler: Kessler, The Beast]] From {{inFAMOUS}}
* The Burning Legion in the ''{{Warcraft}}'' has, as its goal, nothing less than the complete eradication of all life in the universe -- and, according to the BackStory, has already destroyed several ''thousand'' planets by the time it reaches Azeroth.
** Occasionally overlapping with the Burning Legion are the Voidwalkers, who are creatures of pure entropy who exist only to devour the physical world. One of their leaders, Dimensius, is responsible for destroying the Ethereals' homeworld. [[DidYouJustPUnchOutCthulhu Players naturally get to punch him out]].
* The Time Devourer from ''ChronoCross'' is apparently Lavos (or one of his spawn) after being removed from time and getting pissed about how unfair life is. After all, he was just doing what he was meant to do. What right do cattle have to persecute or kill the farmer? So it's now going to eat all of time [[spoiler: by fusing with Schala]]. Or something along those lines. The game is kinda vague about it.
* Marduk the plane-consuming demon from ''{{Sacrifice}}'', whose mere presence on a plane of existence leads to its eventual decay and, ultimately, its complete destruction.
* In ''Super PaperMario'', BigBad Count Bleck doesn't just want to destroy the world, he wants to destroy the ''multiverse'' and remake it in his image.
**[[spoiler: Actually, that ambition belongs to [[TheChessmaster Dimentio]]. Bleck was willing to just let everything stay destroyed.]]
* The Shivans from the ''[[{{Freespace}} Descent: Freespace]]'' series are an entire ''race'' of Omnicidal Maniacs. They've managed to destroy The Ancients, a civilization that was way bigger and more advanced than the Terran and Vasudan races combined. In fact, they've been named after Shiva, "The Destroyer", ''because'' they never attempted to communicate and only seems to be interested in blowing up stuff that ''isn't'' Shivan. The first game had cutscenes which chronicle the rise and fall of the Ancients from the Ancients' perspective (complete with OminousLatinChanting), and they call them "The Destroyers". The cutscenes reveal that the Ancients figured out a way to defeat the Shivan menace, but it was too late. This [[LostTechnology Ancient information]] was later discovered by Vasudan scientists giving the Terrans and Vasudans just enough time to save their collective arses. But not before [[spoiler:the Vasudan homeworld was completely leveled, killing four billion of them, and just ''right'' before the Shivans got to Earth. That's right, not one but TWO (!!) of the most advanced, space-faring races this side of the galaxy would have been wiped out by the Shivans, if it weren't for artifacts left from a ''very'' advanced civilization that they ''did'' wipe out.]]
** Thirty-two years later in ''Freespace 2'', the Shivans even manage to [[spoiler:cause a star to supernova, in a system with billions of civilians in it.]] Granted, that time around killing non-Shivan stuff didn't ''seem'' to be their ''primary'' objective. They just killed ''everyone who got in their way''. And to heck with collateral damage from the [[spoiler:supernova]].
** In both games, there are speculations from all sides as to why the Shivans seem so hell-bent on killing everyone. The Ancients thought they deserved their fate, for subduing "lesser" civilizations in their conquest of the galaxy. A Terran voice at the end of the first game mentions Shivans as a protector, sort of immune system of the galaxy, wiping out any civilizations that discover subspace to prevent them from being a threat to the younger, less advanced ones. The rogue Admiral Bosch from ''Freespace 2'' thinks [[spoiler:humanity has no future with the Vasudans, we're talking about an alliance with the Shivans, man!]] Admiral Petrarch, your [=FS2=] boss, thinks Shivans are like the Terrans, wandering the galaxy for a way back home ([[spoiler:the subspace link to Earth was cut off when the SD Lucifer blew up in subspace in the first game]]). Nobody really knows though, and the Shivans are unique in that they're a mystery race that actually becomes ''more'' mysterious as the series progressed. [[LeftHanging Nobody will ever know, either]], space sims are dead and the original publisher is bankrupt.
* Gig from ''SoulNomadAndTheWorldEaters'' fits this trope to a T... And he's [[HeroicSociopath on]] ''[[HeroicSociopath your]]'' [[HeroicSociopath side]].
** [[spoiler:There's also Revya him/herself in the Demon Path, who ends up ''unmaking existence'' in the 'bad' ending.]]
* In ''[[KnightsOfTheOldRepublic KoTOR]]'', Darth [[MeaningfulName Nihilus]] seeks to devour all life in the galaxy.
--->'''Visas Marr''': "He is a wound in the Force, more presence than flesh, and in his wake life dies… sacrificing itself to his hunger."
* ''StarControl 2'': "We are the Ur-Quan Kohr-Ah. We cleanse. You are the filth."
* Prince Luca Blight from ''SuikodenII'' is a combination of this trope and a AxCrazy. Needless to say, [[CompleteMonster he's not a very pleasant guy...]]
* [[spoiler:Dorian General Grants]], the BigBad of ''TalesOfTheAbyss'', sought to annihilate the entire surface of the planet the game's set in, down to the last molecule, and build a new world upon it from scratch.
* The [[spoiler:Reapers]] in Mass Effect allow life to evolve and advance to a certain level, then come out from hiding to go on a killing spree wiping out almost all life in the galaxy, after which they go back into hiding, and the cycle repeats and has done so for millions of years. The reasons are not explained, apparently because organic beings are too weak and puny to understand.
* After [[spoiler:Galcian dies]] in ''SkiesOfArcadia'', [[spoiler:Ramirez]] goes insane and shoots for the destruction of the entire world, stating that it is no longer worthy of living. [[spoiler:He even gives up his life to fuse with the Ancient Superweapon for Unlimited Power to destroy.]] In doing so, he mirrors the words of [[spoiler:the Silvite Elders]], who had the same goal but lacked the means.
* The BigBad of ''LiveALive'', [[NamesToRunAwayFromReallyFast Demon King Odio]], is a great example. This holds true to various degrees in all of the chapters of the game, especially the medieval chapter, which doubles as his [[spoiler: StartOfDarkness]].
* Mortimer [=McMire=] from the ''CommanderKeen'' games. In the first game trilogy he attempts to destroy Earth because he considers the human race TooDumbToLive. After that fails he decides to blow up the whole galaxy instead. And then it turns out that the galaxy destroying scheme was just there to distract the hero, and his true goal is nothing less than the destruction of the entire universe! Sadly the next game was never made.
* The Void from the EverQuest universe and Big Bad of EverQuest II are a whole dimension's worth of these, by virtue of being the anthropomorphic embodiment of nothingness from before the dawn of creation. They are credited with the destruction of at least five other worlds prior to targeting Norrath and one alternate future shown in the bad ending of a mini-game scenario shows that they are more than capable of wiping Norrath from existence too should its denizens falter in their defense.
* ''Mastermind, World Conqueror'', from the on-line game of the same name. You play as this villain and your goal is to destroy the earth.
* The Covenant in the ''Halo'' series are a doomsday cult led by omnicidal maniacs, the Prophets. They [[EarthShatteringKaboom glass every planet they take]] after plundering it for Forerunner artifacts, and try to activate the titular {{Doomsday Device}}s to destroy all sentient life in the galaxy, believing it will lead them to AscendToAHigherPlaneOfExistence.
* ''ImpossibleMission'': Professor Elvin Atombender, a MadScientist who is attempting to hack the world's nuclear missile codes and [[EarthShatteringKaboom destroy the planet]].
* The CosmicHorror that is the W'rkncacnter in the ''Marathon'' series.
* In {{Pokemon}} Diamond, Pearl and Platinum, [[BigBad Team Galactic Boss Cyrus]] wants to use the time-and-space bending powers of [[OlympusMons Dialga and Palkia]] to destroy the current world and build a new one [[AGodAmI in his image]].
** He comes even closer to succeeding in Platinum, but is stopped at the last second by [[spoiler:Giratina, which ironically is the Pokemon symbol of death.]]
*The planet Meteo from ''{{Meteos}}'' is a gargantuan malevolent eye that wants to destroy everything in the universe via the endless hordes of meteors he spawns.
* In HouseOfTheDead, final boss Magician's first words are "Who are you? Nobody gives me instructions. I shall destroy everything." In House Of The Dead 3, final boss Wheel of Fate opens the fight with "I will destroy everything. And resurrect everything." [[spoiler:They sound the same for good reason, as the Wheel of Fate is none other than [[EvilutionaryBiologist Dr. Curien]], Magician's creator.]]
* Lord Ghadius of ''{{Klonoa}}: Door to Phantomile''. His quote on the quote page is rather chilling.
* Mehrunes Dagon, the Daedra Prince of Destruction of ''TheElderScrolls'' verse.
* [[spoiler:Porky]] in ''{{Mother 3}}''. He wants to destroy the entire world, [[spoiler:because he's gone even more insane as a result of the TimeAbyss he went through, and that still nobody loves him.]] Slightly different from the usual in that [[spoiler:he already HAS destroyed the world, and that these people are the last remaining survivors.]]
* Requiem from ''CityOfHeroes'' plans to turn Earth into a homeworld for the Nictus. While that may not be enough to qualify him as an OmnicidalManiac, you discover an alternate dimension where Requiem's plans have succeeded, and he's [[LonelyAtTheTop gone insane from being the only human left]] and is trying to destroy the entire multiverse.
* You know you're living in what amounts to a [[CrapsackWorld crapsack universe]] when these are the kinds of guys in charge. Such is the cosmos in [[spoiler:''[[{{Boktai}} Lunar Knights]]'', with the Immortals running around with their [[PlanetEater Planet Eaters]], taking over all sorts of worlds and/or destroying them to impose eternity upon the universe. Granted, Lucian and Aaron make life much easier for their world by completely erasing Polidori (he's an Immortal, in case you lost track), but if [[NiceJobBreakingItHero what Dumas said has any weight to it]], there are going to be a lot more on their way...]]

* In ''Kid Radd'', the PixelArtComic masquerading as a SpriteComic, a character 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.
** 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 dependant on computers, or indirectly. However, what really takes the cake is [[spoiler: The Seer]] who doesn't just want to destroy Earth, but realizes that with all the stars and planets out there, there HAS to be life on some of them. So that when he's done with Earth he will travel to one of those and kill everything there.
* [[spoiler:The Snarl]] from ''OrderOfTheStick''.
** Though recent events have opened up ''all kinds'' of questions about this.
* ''EightBitTheater's'' Black Mage. These days, every other strip at least mentions to his desire to kill everything in existence just for the heck of it. He may be slightly justified, as WordOfGod says the universe exists to make Black Mage's life a living hell. Then again, considering his intentions, the universe's tendency to blow up, smash, and/or inconvenience Black Mage at every opportunity may well simply be self-preservation. A real chicken-and-egg scenario...
* O'Malley, the BigBad of 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."
* Zorgon Gola from ''SluggyFreelance'' [[http://beta.sluggy.com/daily.php?date=010730 appears]] to be an OmnicidalManiac, but this is actually part of a XanatosGambit [[http://beta.sluggy.com/daily.php?date=010816 to make himself]] a mere GalacticConqueror. [[spoiler:Unfortunately, Gola didn't count on the actions of three [[SpannerInTheWorks Spanners In The Works]] ([[WhatTheHellHero our heroes]]) causing his [[XanatosGambit Gambit]] to ''actually'' [[NiceJobBreakingItHero destroy the Punyverse]]]].

* [[SCPFoundation SCP-682]] is a strange, seemingly-reptilian "creature" -- the term creature can be used only loosely, as it doesn't seem to be truly alive -- that considers all living things disgusting sub-beings that must be destroyed. Well, all of them except CreepyChild 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 OmnicidalManiac 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 implied to be out of a ''really'' extreme version of HumansThroughAlienEyes.

* Unicron from ''{{Transformers}}'', particularly in ''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, but because existence is somehow offensive to him. Megatron/Galvatron may be considered an accessory to the crime(s).
** This is Megatron's actual goal when the last part of ''TransformersCybertron'' rolls around. He wants to use the black hole and the Cyber Planet Keys to destroy the universe so he can rebuild it in his own image. Somehow.
* Daemon from {{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.]] Of course, 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.
* The Brains from ''{{Futurama}}''. These unbelievably powerful, [[MindRape mindraping]] 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}}, [[spoiler: the Nibblonians]]. Unlike typical PlanetLooters, the Brains actually ''enjoy'' their omnicidal campaign. The Brains are basically Brainiac from the DCAU but they're an ''entire race'', not just one evil AI. Thanks to there being no {{Superman}} to fight them, the Brains come damn close to succeeding.
** Lucky for humanity, Fry was immune to their mind powers. Then he made them leave the Earth for [[RougeAnglesOfSatin ''no good 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 [[spoiler: the Nibblonians]] manage to stop them again.
* DannyPhantom becomes this in an alternate future, pretty much. 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.
* In the 90s ''Spider-Man'' animated series, for the big climactic series finale, an alternate universe Peter Parker is bonded to the Carnage symbiote to become Spider-Carnage. Already kinda unbalanced due to his clone hogging the spotlight (in a clever nod to the [[SpiderMan Clone Saga]]), he now becomes obsessed with not merely destroying the earth, or the galaxy, or the universe, but ''ALL'' universes!
* The Heys from ''TheTick''. Played with the usual tongue-in-cheekness of the series, but their motivations are purely omnicidal.
* Darkseid from the ''{{DCAU}}'' has the ultimate goal of obtaining the anti-life equation and using it to undo the current existence, so he can rebuild it in a manner more to his liking. Unfortunately it tends to be overshadowed by his 'torment Superman' schemes.
** Brainiac, also from the {{DCAU}}, acts to destroy all of creation, but this is due to his programming rather than any genuine malicious wish to do so.
*** Omnicidal [[IncrediblyLamePun Brainiac]], you might say.
* ''TheFairlyOddparents'' has two. First, Dark Laser really wants to blow up the Earth because...well, it's there. A more serious example is [[BigBad The Darkness]], a powerful and ancient entity who has destroyed countless worlds, including [[spoiler: 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 is at hurting it]]
* Dr. Blight from Captain Planet talks about wanting to actively destroy the planet in some episodes but her goals change from episode to episode.
* Trigon of TeenTitans had the explicit goal of destroying "the world of mortals", though he did plan on remaking it in his own image afterwards. As this would mean a ''literal'' hell on earth, it doesn't make him any less evil than the others on this list.
* {{The Real Ghostbusters}} had one guy who wanted to destroy the world because he felt it was a bad place. Fot that, he summoned a magical artifact - using [[LordOfTheRings The Ring Inscription]].
