History OmnicidalManiac / ComicBooks

* In ''ComicBook/{{Crossed}} +100'', Beauregard Salt was a SerialKiller who was [[TheImmune rendered immune]] to the HatePlague because he was ''already'' a murderous psychopath, and he was elated to live in a world where everyone sees things the way he does. [[ToCreateAPlaygroundForEvil Not wanting his fun to end]], he formed a clan of [[SanityHasAdvantages intelligent]] [[EliteZombie infected]] and taught his followers PragmaticVillainy with the intent of wiping out baseline humanity to keep his VillainWorld intact [[VillainousLegacy even long after his death]].

* ComicBook/JohnnyTheHomicidalManiac implies in the former half of the series that Johnny may be at the center of the universe and that if he dies, all will cease to exist. This turns out to be true when a robotic arm with a gun he created shoots him in the head. As he slowly bleeds out, a Lovecraftian monster breaks free from his walls and destroys everything. Outside his home reveals to be an endless void. This becomes an AvertedTrope when Satan brings him back to life thus reseting the world to its former self.

* ''ComicBook/SonicTheHedgehogArchieComics'' had Dr. Finitevus, who firmly believes that the world is corrupt and needs to be "purified in emerald fire". That's the reason he [[ManipulativeBastard manipulated]] Knuckles into becoming the new [[PhysicalGod Enerjak]], knowing that the power would drive him crazy and lead to him going on a rampage. He hasn't tried anything major since, but he's still convinced of the righteousness of his actions and there were hints that he had big plans before he was ExiledFromContinuity [[ScrewedByTheLawyers by the Lawyers]].
** Then, Dr. Eggman, at the end of ''ComicBook/SonicTheHedgehogMegaManWorldsCollide'' did this ''accidentally,'' causing a ContinuityReboot (necessitated by the aforementioned legal issues) that removed over half of the comic's cast.
* In ''ComicBook/SonicTheComic'' destroying the world appeared to be the entire motivation of Knuckles' arch-enemy, the evil echidna [[MadScientist Dr. Zachary]]. When he first appeared, he boasted of his plans to locate and destroy the other echidnas ''after'' he had destroyed Mobius as a warm up, and [[CardCarryingVillain quite happily acknowledges]] the fact that [[AxCrazy he's evil]], and in ''Webcomic/SonicTheComicOnline'' he manipulated [[AntiVillain Shadow the Hedgehog]] into destroying the Special Zone, and almost did the same to Mobius if it weren't for Sonic [[DealWithTheDevil asking for help from the Drakon Empire]].
** The only character who manages to be even ''more'' omnicidal than Zachary is Sonic's SuperpoweredEvilSide, Super Sonic, who had no real plan beyond destroying whatever was at hand when Sonic transformed.
** After a VillainousBreakdown Dr. Robotnik gives up trying to rule Mobius and tries to destroy it outright.
** In ''Webcomic/SonicTheComicOnline'' there is also the God of Death Vichama.
* Talita from Terror,Inc was trapped between [[FateWorseThanDeath life and death]] in [[TheNothingAfterDeath a void of blackness]] for 800 years. She went completely mad and came to love the Void. After she was resurrected she feared her commitment to the Void: ''"I feel...a strength coursing through me...yes...yes...I worried I might lose faith as the pain left me. I feel joy,strength,lust all raging through me...ALL PALE BEFORE THE EMPTINESS".'' Before she ends the world she wants to taste life followed by [[CessationOfExistence nothing]].
** [[HarbingerOfImpendingDoom Aban]], a [[PlagueMaster plague carrying immortal young boy]] wants to [[WhoWantsToLiveForever die]] but can't so in his frustration he wants to [[SuicidalCosmicTemperTantrum end the world]] hoping it would kill him. He refers to himself as a [[StrawNihilist true nihilist]] and [[ForTheEvulz enjoys killing]].

** Deadside in the old Valiant Universe was a terrible place where all souls eventually come no matter how they lived be it good or evil.There is no Heaven nor Hell. Billions upon billions of souls trapped for all eternity [[AndIMustScream screaming in madness]]. In the new Valiant Universe it seems to be toned down a bit but it's still a terrible place where lost souls find no peace. Darque also comments on the nature of souls and its curse: "''Even the smallest of them. There is something in all of use that persists beyond death. You would call this a soul. The essence of a thing that is indestructible. Something that survives. Something that fears. Something that suffers. This is cruelty. This is madness. To know that your suffering will never end. Because that is the point of the soul. Suffering without limit. Without Surcease.''"

* The Ogdru Jahad from ''ComicBook/{{Hellboy}}'' want to burn the Earth to a cinder

*** The [[EvilCounterpart Dark Judges]] have a philosophy that boils down to this. Undead psychopaths devoted to Law, they figure that since only the living commit crimes, life itself should be made a crime that is punishable by death. They slaughtered the entire population of their world, then found themselves stuck, as they hadn't any form of space travel, making them come off more as KillAllHumans in practice. They've killed the occasional alien traveler who made the mistake of visiting their world, though.

* The light-hearted nature of ''[[ComicBook/{{Shazam}} Captain Marvel]]'' can distract you from Sivana being this in one story. Because Captain Marvel prevents Sivana's plan to take over the Rock of Eternity so he can take over the Universe, Sivana tries to activate a Proton Bomb to destroy the Rock of Eternity, which is the Keystone of the Universe and will cause its destruction, even killing himself, deciding if he can't rule the Universe [[IfICantHaveYou he'll wreck it]]. He is even laughing at this as he wants one last laugh. [[http://digitalcomicmuseum.com/preview/index.php?did=16428&page=33 Just look at his reaction]]
* DC Comics' [[CrisisCrossover crisis crossovers]] have the following:
** ''ComicBook/CrisisOnInfiniteEarths'': Anti-Monitor, whose stated goal is to rule an Anti-Matter universe after all other universes have been destroyed and he has absorbed the energy from their destruction
** ''ComicBook/ZeroHour'': Parallax (Hal Jordan, though the circumstances of it was changed during ''Green Lantern: Rebirth'') and Extant
** ''ComicBook/InfiniteCrisis'': Alexander Luthor and Superboy-Prime, who both want to create their own version of the "perfect Earth" and don't care how many different versions of Earth from other realities they need to use as raw material.
** ''ComicBook/FinalCrisis'': ComicBook/{{Darkseid}} (who, upon discovering he is dying, decides to destroy the entire multiverse) and Mandrakk (who more or less feeds on existence and is on a hunger rampage). Darkseid even provides the trope's image.
** ''ComicBook/BlackestNight'': Nekron (An embodiment of death itself, which naturally wants to kill everything)
** ''ComicBook/DarkNightsMetal'': Barbatos, a ruler from the Dark Multiverse where worlds are born out of fears and hope the people make before rotting away into oblivion, recruits seven [[EvilCounterpart evil counterparts]] of ComicBook/{{Batman}} in order to bring the DC multiverse into darkness.
*** The Joker of Earth -22 becoming one of these, systematically killing off every hero, villain and civilian in Gotham City in order to "end the story" and create something else leads directly to the creation of [[HeWhoFightsMonsters the Batman Who Laughs.]]
* The Cult Of The Unwritten Book from ''ComicBook/DoomPatrol'' seek to summon [[NamesToRunAwayFromReallyFast The Anti-God]] and reverse creation by "reading" The Word Made Flesh.
* Doomsday from Franchise/TheDCU. The name says it all. He's also one of the most primitive examples, he's little more than a frightened but sadistic alien man-child who wants to kill everything that might be a threat to him. And he thinks ''everything'' is a threat.
* Imperiex, 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 it detected in the universe was itself, 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, a fact which Imperiex realizes the moment before it dies]].
* While he does not typically fall under this category, ComicBook/TheJoker did, in fact, reach this state during the "ComicBook/EmperorJoker" plotline in the ''ComicBook/{{Superman}}'' comics, with his reasoning being that a universe that would spawn something as twisted as he was didn't deserve to exist (and besides reality was falling to pieces from the strain anyways). 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.
* Adolf Hitler in ''ComicBook/LastDaysOfTheJusticeSociety'' becomes this near the end of World War II, when he realizes that he and his Nazi forces are near defeat. Using the SpearOfDestiny, Hitler links the fate of the Norse gods' Ragnarok with that of the universe itself, causing everything to go in flames from 1945 onward through a DelayedRippleEffect.
* ''ComicBook/{{Legion of Super-Heroes}}'':
** Braniac-5 pre-Crisis. After being driven mad, he wanted to destroy the entire universe, and stole the Miracle Machine that could do ''anything'' the user could envision. He could have easily destroyed the Earth, or even several planets of similar size, but he couldn't envision destruction on the grandiose scale he wanted. So he used the Machine to create something that could, [[TheJuggernaut the unstoppable]] [[ThePowerOfHate embodiment of hate]], [[AnthropomorphicPersonification Omega]]. Had this beast actually reached the Machine (and the Legion could do little to even slow it down) Braniac-5's plan would have succeeded; they foiled it when Matter-Eater Lad destroyed the Machine by eating it, [[HeroicSacrifice but was driven insane in the process.]]
** The Legion's foe Time Trapper has their desires and motivations subject to change alongside their mutable identity but at points, such as in ''ComicBook/CosmicBoy'', their goal is the erasure of all time between the entropy at the end of the universe they're a [[AnthropomorphicPersonification personification of]] and that which came before, thereby erasing everything and everyone who has or ever will exist.
* ''ComicBook/{{Lucifer}}'': Fenris the Wolf is Destruction personified (and likely an aspect of Destruction of the Endless). His goal is to destroy Creation by attacking the seat of God in Heaven. Lucifer stands in his way.
** Fenris is assisted in his endeavor to end all of creation by the gods [[TheTrickster Abonsam]] and Bet Jo'gie. Abonsam infused with the essence of Fenris willingly gave his life to perform his greatest trick and ultimately dooming [[WorldTree Yggdrasil]]. Bet fails in her attempt to seduce [[AxCrazy Charlie]] and dies by his hands.
** The [[SapientShip Barrowjane]] Conspirators to destroy Creation, dethrone God and punish him included [[WomanScorned Lilith]], [[FallenAngel Sandalphon]], [[DimensionalTraveler The Silk Man]] and [[PrimordialChaos Berim from the Jin En Mok]]. All had their own reasons for participating: Lilith wanted vengeance against God and Heaven for casting her out of Eden, Sandalphon wins the victory that was denied to Lucifer, The Silk Man wants his own universe and when creation ends the Jin En Mok will finally be reborn as themselves.
* One of the [[MultipleChoicePast four possible backstories]] for ComicBook/ThePhantomStranger 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.''
* The [[SinisterMinister Reverend Jeremiah Hatch]] from Franchise/TheDCU. A brilliant student but [[TheMentallyDisturbed mentally unstable]] he was dismissed from seminary and flunked out. He went to Vietnam pretending to be a chaplain. The ugliness of the war he witnessed [[GoMadFromTheRevelation broke him]] and he started hearing a [[HearingVoices malicious voice]]. Jeremiah realized that life is a nightmare from which there is no awakening and he threw away his cross followed by butchering both allies and enemies alike. His new mission is to serve the Almighty by serving his enemy:''"To hasten the corruption,to nurture the foulness until the Almighty has no choice but to rain down fire and brimstone and end the ugliness,the pain, the suffering".'' His [[CorruptPolitician corruption of the Mayor of Hub City]] was to get him into the [[PresidentEvil White House]] and start [[WorldWarIII an apocalyptic war]].
* In ''ComicBook/{{Supergirl}}'' series ''ComicBook/SupergirlCosmicAdventuresInThe8thGrade'', Mr. Mxyzptlk attempts to break down several whole dimensions and reality planes in order to power himself up.
* From the ''Wildstorm'' universe:
** Jenny Fractal is the twin sister of ComicBook/TheAuthority's Jenny Quantum, kidnapped at birth by the Chinese government. [[TykeBomb She was put in an assassin program]] where she was [[BeingTorturedMakesYouEvil forced to watch humanity's evil deeds: rape, murder, genocide, etc]]... She has the power to fracture/alter reality and wants to use the Earth as the center of a black hole to implode and collapse the entire multiverse. Her reasons for doing this: "It's the only way to save them".
** Winter of ''ComicBook/{{Stormwatch}}'' becomes this after he flew an Franchise/{{Alien}}-infested Skywatch space station into the sun to save the world. Being an energy absorber, Winter became one with the sun. Trapped by eternal agony he lures out ComicBook/TheAuthority so they can finally put an end to his life; when it's deemed impossible to kill him without destroying the sun and ending the world, he became enraged. Disgusted by humanity's cruelty, he yells "Your world does not deserve to live" and lashes out. [[spoiler:He's eventually stopped by using the Carrier's technology to seal baby universes and was condemned to burn for billions of years. Later on he's released by the new Doctor and revived in his previous normal state. In the latest ''Stormwatch'' issues it was revealed he still holds some of the sun's power.]]
** "The Man Without Hope" (MWH) comes from the future and with his superior technology he's a match for ComicBook/TheAuthority. The future is grim, blank and full of suffering and he wants to prevent it from happening by ending existence all together. Swift receives knowledge from the mythical "gods" about the dark future and how to prevent it. She mentions how the MWH with all his technology couldn't figure out the problem and fix it. The MWH commits suicide when his plan is ruined by The Authority and a new unknown time line is birthed yet he is still convinced that everyone is screwed. The issue ends with the words "beginning of the end" hinting that the MWH was probably talking about human nature being the problem seeing it's the central theme of the graphic novel, "human on the inside"
* ''Franchise/WonderWoman'':
** ''ComicBook/WonderWoman1942'': Adjudicator justifies his actions as judgement on the peoples of whatever world he's currently destroying across the multiverse, but he "judges" the planets before sending minions to test the inhabitants of a handful of the representative versions of the planet and that judgement always calls for the destruction of the planet(s) and its/their inhabitants.
** ''ComicBook/WonderWoman2006'': Genocide despised sentients, and her goal upon "birth" was the extinction of the human race.
** ''ComicBook/WonderWomanOdyssey'': Nemesis reasoned that she could only fulfill her purpose by destroying humanity entirely. Given that there are other races capable of committing murder in her universe she would have likely found that her job wasn't yet complete with only humanity destroyed.

[[folder:Marvel Comics]]
* Abraxas also hails from the Franchise/MarvelUniverse. The antithesis of Eternity, it exists only to destroy anything and everything in all creation. Keeping it imprisoned is one of the reasons ComicBook/{{Galactus}} needs the life energy from devoured worlds. The one time Abraxas ''did'' break free it... wasn't pretty.
* Amodeus Q. Termineus from the Marvel universe sought the shattered fragments of the Nexus of all Realities. With them in possession he could destroy the Multiverse.
* Annihilus, also from the MarvelUniverse, became one of these during the ''ComicBook/{{Annihilation}}''. His vast fleets carved a path of devastation across the galaxy, used a large, tick-like weapon called the Harvester of Sorrows to drain entire planets of their energy to ''feed'' on, 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 Omnicidal Maniac 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.
* Amatsu-Mikaboshi from the ComicBook/ChaosWar CrisisCrossover is also this. He existed long before the universe did and, in the Chaos War, wants to return things to that state. Marvel sure is in love with this trope.
* The Cult of Entropy seeks to speed up the destruction of the Marvel Universe/Multiverse.
* ComicBook/SpiderMan's ArchEnemy ComicBook/DoctorOctopus became this during the "ComicBook/EndsOfTheEarth" storyline. Knowing he was dying, his plan was to use powerful satellite weapons to kill 99% percent of the population of the Earth so that the remaining 1% and all of their descendents would remember him forever. He nearly succeeded. However, just as he was about to pull the switch, Spider-Man pointed out a flaw in his plan: the incredible heat caused by the weapons would leave all the survivors brain-dead. This revelation caused Octopus to hesitate long enough for the hero to pummel him into unconsciousness. [[spoiler: However, it is then revealed that Octopus pulled a MindSwap on Spider-Man and was then running around as Peter Parker, vowing to do a better job being Spider-Man than he ever did. It is ambiguous if Octopus thus had a change of plans or if the attempt to wipe out most of mankind (along with the flaw therein said attempt) was just an elaborate ruse to pull of the MindSwap plan all along.]]
* All of the Elders of the Universe of Marvel Comics came up with a purpose to keep from going mad from their immortality, but one of them, the Obliterator, was clearly insane from the start. After murdering his entire species, he wandered the universe looking for things to kill, using his powerful high-tech weapons to shoot at anything that moved. (Except the other Elders, the only beings who come close to being his allies.) Fortunately for the universe at large, he has no real confirmed super-powers other than the immortality that all the Elders have (possibly making him the least powerful of the group) and is also not very smart.
* Maelstrom from the Marvel universe. He's the champion of Oblivion and constantly schemes to destroy everything.
* On a more planetary scale, ComicBook/{{Onslaught}} started out as a [[KillAllHumans mutant supremacist]] of the same stripe as his psychic 'father', Magneto. After seeing the Age of Apocalypse in Bishop's memories, in which mutants really did rule the world and destroyed it, he decided no one was worthy.
* ComicBook/{{Thanos}} is the most famous Franchise/MarvelUniverse 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 wreak death and destruction. Although he ''has'' stated on multiple occasions that the elimination of ''all'' life might destroy Death as well as it would eliminate her need to exist, so he would eliminate ''half'' of all life, thus ensuring Death still has a steady supply of souls.
** In ''ComicBook/TheThanosImperative'' Thanos goes completely insane when he realizes that [[spoiler:his ThanatosGambit to destroy the Cancer Verse also rendered him immortal, meaning he can never be with Death.]] He makes an earnest effort to wipe out all life in the Marvel-616 Verse [[spoiler:and has to be sealed in what's left of the Cancer Verse to stop him from pulling it off.]]
* ''ComicBook/UltimateXMen'': Most plans of Magneto aim to a worldwide culling of the human race. And he finally achieved that during ''ComicBook/{{Ultimatum}}''.
* ''ComicBook/XMen'' villain Cassandra Nova takes a strange approach to this. Due to the circumstances behind her existence (namely, as the self-constructed remnants of an EvilTwin killed in the womb), she's convinced she and Charles Xavier are both still in the womb, and the only ''real'' things in existence; everything else is but an ideation of theirs, a piece of their imagination. And since she's so fundamentally opposed to Charles, she wishes to destroy this "imagined" universe completely just to torment him, starting by those mutants he champions so much. On the latter count, she's sixteen ''million'' corpses in and counting.
* ''ComicBook/XMen92'': OriginalGeneration villain Xodus the Forgotten combines this trope with FinalSolution, as he is a FantasticRacist Celestial who traveled from world to world exterminating any and all {{Mutant}} populations until his Celestial brethren made him a SealedEvilInACan. Predictably, the seal is broken and he heads to Earth to pick right back up where he left off.
* In ''ComicBook/DoctorDoom2019'', [[spoiler:Doctor Doom becomes this in the final issue when he destroys an entire universe because he hates what his counterpart (whom he had just murdered) did to make it a paradise. Namely, the alternate Victor became a humble man who befriended Reed Richards and worked together with him to make the universe a better place. Doom would rather kill a universe than accept that he should let go of his pride and his hatred of Richards.]]
[[/folder]]

** ''ComicBook/FinalCrisis'': ComicBook/{{Darkseid}} (who wants the Anti-Life equation to subjugate the whole thing, tear it down and rebuild it to his liking) and Mandrakk (who more or less feeds on existence and is on a hunger rampage). Darkseid even provides the trope's image.

* John "Grimjack" Gaunt walks away from Heaven [[SenselessSacrifice to save his friends]]. The consequences were that he was denied any afterlife and was [[WhoWantsToLiveForever doomed to be reborn remembering his memories for all eternity]]. His soul was bound to the pan dimensional city known as Cynosure. Cynosure was build to harvest the energies of the multiverse to an entombed supreme being called [[TheMaker Dis]] (firstborn of the multiverse) until it was ready to repeat the birthing process in an unending cycle. [[FutureMeScaresMe Grimjack's latest incarnation]] travels back in time to warn himself of the doom and to [[DeathSeeker break it]] he has to end the multiverse by destroying Cynosure.[[spoiler: Future Grimjack succeeds in manipulating present John in freeing the Supreme being from his sleep.]] In Grimjack's second incarnation we see the Supreme being walking around in mortal form giving the demons the chance to end his life and let the multiverse die in entropy. They fail. A huge hint that the multiverse might end up destroyed can be seen in Grimjack's supposedly real father, his [[LukeIMightBeYourFather uncle Jack]]. He is a Fey and can look into the future. He describes to a young grimjack the complete dissolution of the multiverse, saying there will be "nothing" after that and also that Grimjack's death would be the most interesting of all. We never see if future Grimjack succeeds because the series ended with the death of the second incarnation.

* Skynet in ''Comicbook/RoboCopVersusTheTerminator'' becomes this in one timeline where it managed to KillAllHumans. It sends out fleets of starships to kill ''everything else''.

* According to [[DependingOnTheWriter some versions]] of the character (particularly the [[Comicbook/ThePunisherMAX MAX universe]]), if Comicbook/ThePunisher were given enough time and ammo he would kill every person on Earth.

This revelation caused Octopus to hesitate long enough for the hero to pummel him into unconsciousness. [[spoiler: However, it is then revealed that Octopus pulled a MindSwap on Spider-Man and was then running around as Peter Parker, vowing to do a better job being Spider-Man than he ever did. It is ambiguous if Octopus thus had a change of plans or if the attempt to wipe out most of mankind (along with the flaw therein said attempt) was just an elaborate ruse to pull of the MindSwap plan all along.]]
* All of the Elders of the Universe of Marvel Comics came up with a purpose to keep from going mad from their immortality, but one of them, the Obliterator, was clearly insane from the start. After murdering his entire species, he wandered the universe looking for things to kill, using his powerful high-tech weapons to shoot at anything that moved. (Except the other Elders, the only beings who come close to being his allies.) Fortunately for the universe at large, he has no real confirmed super-powers other than the immortality that all the Elders have (possibly making him the least powerful of the group) and is also not very smart.
* Amatsu-Mikaboshi from the ComicBook/ChaosWar CrisisCrossover is also this. He existed long before the universe did and, in the Chaos War, wants to return things to that state. Marvel sure is in love with this trope.

* ''ComicBook/TwoThousandAD'':
** ''ComicBook/JudgeDredd'':
*** The [[EvilCounterpart Dark Judges]] have a philosophy that boils down to this. Undead psychopaths devoted to Law, they figure that since only the living commit crimes, life itself should be made a crime that is punishable by death. They slaughtered the entire population of their world, then found themselves stuck, as they hadn't any form of space travel, making them come off more as KillAllHumans in practice. They've killed the occasional alien traveler who made the mistake of visiting their world, though.
*** Sabbat the Necromancer from the ''Judgment Day'' arc is a powerful sorcerer who has made it his mission to destroy all life so he can use the corpses of the dead as part of his undead army.
** ''ComicBook/{{Shakara}}'': The Overlord tells his acolytes in The Hierarchy that he is building the Infinity Engine, an InterdimensionalTravelDevice, so that they can [[MultiversalConqueror extend their evil reign through the entire multiverse]]. In fact, its real name is the God Engine, a DoomsdayDevice that will wipe out all of reality and leave only himself to create a new one that he will rule over as God.
* Ujo Dasa is a dark sorcerer from the Frazettaverse. He planned to free the Oblivion God "Mirahan" by sacrificing a half-breed human/demon and begin the end of everything. When confronted by his former teacher Dreovid, he says it's better to have "cool darkness than searing light".[[spoiler: In the end it was revealed that Ujo was the half-breed and son of Mirahan. The Oblivion God swapped his throne of netherhell with Ujo and we watch him rest in peace.]]
* In DC's take on ''Franchise/MastersOfTheUniverse'', Skeletor becomes this during the climax of "[[GrandFinale The Eternity War]]": [[spoiler: Having [[EvilerThanThou defeated Hordak]] and seized control of the power of Greyskull from him -- and having previously discovered that throughout TheMultiverse, he always loses to He-Man -- he intends to use his new status as a PhysicalGod to cheat the odds by killing everyone and everything, so that he can then rule over a universe of the dead unopposed.]]
* Lord Drakkon of ''ComicBook/MightyMorphinPowerRangersShatteredGrid'' descends into this. [[spoiler:After murdering the main universe Tommy Oliver and causing the Ranger timeline to shatter into multiple universes, he proceeds to go on a rampage through the universes in order to gain enough power to hop into the realm of the Morphin Masters, steal one of their hearts and obliterate the multiverse to rebuild it in his image.]]
* The [[StrawNihilist Mad Angel Apolyon]] from the Chaos!Multiverse stole secret knowledge from God and uncovered the truth that [[GoMadFromTheRevelation nothing really matters]]. Lucifer fearing this truth imprisoned and [[BeingTorturedMakesYouEvil tortured]] Apolyon for a thousand years. After he was released God confided in him that for Heaven to exist, there must be a Hell. Apolyon betrays God and wants to destroy all of creation beginning with Hell. Without its counterpart, Heaven will fall and in turn so will God. In the end as Apolyon said, there will be nothing!

* Skynet in ''Comicbook/RoboCopVersusTheTerminator'' becomes this in one timeline where it managed to KillAllHumans. It sends out fleets of starships to kill ''everything else''.
* ComicBook/JohnnyTheHomicidalManiac implies in the former half of the series that Johnny may be at the center of the universe and that if he dies, all will cease to exist. This turns out to be true when a robotic arm with a gun he created shoots him in the head. As he slowly bleeds out, a Lovecraftian monster breaks free from his walls and destroys everything. Outside his home reveals to be an endless void. This becomes an AvertedTrope when Satan brings him back to life thus reseting the world to its former self.

* The ''[[Comicbook/ArchieComicsSonicTheHedgehog Sonic the Hedgehog]]'' comics have Dr. Finitevus, who firmly believes that the world is corrupt and needs to be "purified in emerald fire". That's the reason he [[ManipulativeBastard manipulated]] Knuckles into becoming the new [[PhysicalGod Enerjak]], knowing that the power would drive him crazy and lead to him going on a rampage. He hasn't tried anything major since, but he's still convinced of the righteousness of his actions and will probably try again.
** Then, Dr. Eggman, at the end of ''ComicBook/SonicTheHedgehogMegaManWorldsCollide'' did this ''accidentally.''

* While he does not typically fall under this category, ComicBook/TheJoker did, in fact, reach this state during the "ComicBook/EmperorJoker" plotline in the ''ComicBook/{{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.

* SpiderMan's ArchEnemy Dr. Octopus became this during the "ComicBook/{{Ends of the Earth}}" storyline. Knowing he was dying, his plan was to use powerful satellite weapons to kill 99% percent of the population of the Earth so that the remaining 1% and all of their descendents would remember him forever. He nearly succeeded. However, just as he was about to pull the switch, Spider-Man pointed out a flaw in his plan: the incredible heat caused by the weapons would leave all the survivors brain-dead. This revelation caused Octopus to hesitate long enough for the hero to pummel him into unconsciousness. [[spoiler: However, it is then revealed that Octopus pulled a MindSwap on Spider-Man and was then running around as Peter Parker, vowing to do a better job being Spider-Man than he ever did. It is ambiguous if Octopus thus had a change of plans or if the attempt to wipe out most of mankind (along with the flaw therein said attempt) was just an elaborate ruse to pull of the MindSwap plan all along.]]

** ''ComicBook/FinalCrisis'': {{ComicBook/Darkseid}} (who wants the Anti-Life equation to subjugate the whole thing, tear it down and rebuild it to his liking) and Mandrakk (who more or less feeds on existence and is on a hunger rampage)

* The [[SinisterMinister Reverend Jeremiah Hatch]] from Franchise/TheDCU. A brilliant student but [[TheMentallyDisturbed mentally unstable]] he was dismissed from seminary and flunked out. He went to Vietnam pretending to be a chaplain. The ugliness of the war he witnessed [[GoMadFromTheRevelation broke him]] and he started hearing a [[HearingVoices malicious voice]]. Jeremiah realized that life is a nightmare from which there is no awakening and he threw away his cross followed by butchering both allies and enemies alike. His new mission is to serve the Almighty by serving his enemy:''"To hasten the corruption,to nurture the foulness until the Almighty has no choice but to rain down fire and brimstone and end the ugliness,the pain, the suffering".'' His [[CorruptPolitician corruption of the Mayor of Hub City]] was to get him into the [[PresidentEvil White House]] and start a [[WorldWarIII War]].
