History OmnicidalManiac / VideoGames

* 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 ''[[VideoGame/{{Boktai}} Lunar Knights]]'', with [[spoiler: 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...]]

* The eponymous Creeper of ''Videogame/CreeperWorld'' subscribes to a philosophy summed up as "The Purity of Nothingness."

* ''VideoGame/DwarfFortress''-At the moment, all you can do in Adventure mode is wipe out all the world's sentient life (The only reason its not ''all'' life is because animals seem to respawn). For extra fun, people often try to kill everyone with a SelfImposedChallenge or two.

** From ''Videogame/FinalFantasyXIV'', [[spoiler: Fandaniel]] wants to end all life on The Source and its Shards, including himself, in one giant paroxysm of pain and suffering, all while he gleefuly revels in the carnage and chaos he creates. This stands in stark contrast to the goals [[spoiler: of his fellow Ascians]], and serves to highlight how absolutely batshit insane he is. There's also [[spoiler:Meteon, a creature created by Fandaniel's past self Hermes, whose sisters discovered countless other worlds and found them dead or dying and decided that it would be for the best to speed things up and take everyone]].

* ''ImpossibleMission'': Professor Elvin Atombender, a MadScientist who is attempting to hack the world's nuclear missile codes and [[EarthShatteringKaboom destroy the planet]].
* According to [[spoiler: Kessler, The Beast]] from ''VideoGame/InFAMOUS''.

* Utsuho Reiuji from ''VideoGame/{{Touhou}}'' became one after gaining her powers (whether this is because she was tricked into godmoding or simply curious of what god-flesh tastes like is up for discussion). Thankfully, the heroines were able to confront her before she got a strong handle on her new powers.

** In ''VideoGame/WorldOfWarcraft''[='=]s third expansion pack, the {{Big Bad}}, Deathwing, is an example of this. When fighting him [[spoiler: he has an attack called cataclysm which is meant to completely destroy all life on Azeroth. If he succeeds via this attack or some other, as is shown in the [[BadFuture End Time]], He would have then killed himself to extinguish all life in the world.]] His minion/son, Ultraxion, [[spoiler: also has an ability, Hour of Twilight, that kills the dragon aspects and allows Deathwing to take over the world (and proceed to extinguish all life).]]

** The main one is [[spoiler:Flowey the Flowey aka Asriel Dreemurr, a child who had died and was reincarnated without the ability to feel most positive emotions (love, hope, compassion) due to resurrecting without a soul. Flowey lived his life in every possible way due to his ability to save and load (just like you can!) and not only did he grow incredibly bored with his life, but the way people lived and the memories of how he was killed caused him to take up the attitude of "kill or be killed". In his Omega Flowey fight on the Neutral Route, he absorbs the six human [=SOULs=] to become a god and show everyone, both humans and monsters, "the TRUE meaning of this world". In the GoldenEnding, Flowey regains his true form as Asriel Dreemurr and aims to erase the timeline and start from the beginning so that he can "play" with the protagonist forever by killing them over and over.]]

* ''VideoGame/{{StarCraft II}}'': the Dark Voice plans to use the Zerg and the hybrids to wipe out the Terrans and the Protoss, and once they're done with that, the hybrids will kill all the Zerg so they can reshape the galaxy themselves. [[spoiler:It's eventually revealed that the entire reason Amon is doing this is because the Xel'Naga are not actually a species but rather, a group of beings uplifted with the power and purpose to seed the universe with life. Eventually two races capable of housing the essence of a Xel'Naga would arise, at which point the Xel'Naga transfer their essence into them, [[AscendedToAHigherPlaneOfExistence creating a new generation of Xel'Naga and starting the Infinite Cycle anew]]. However, as the Xel'Naga [[AlienNonInterferenceClause refuse to interfere with the development of their successor races]], [[LockedOutOfTheLoop said successor races are not told about the true purpose of their existence ahead of time]]; Amon in particular was explicitly transformed into a Xel'Naga against his will, [[RageAgainstTheHeavens causing him to develop an intense hatred of the Infinite Cycle as nothing but a source of suffering for everyone involved]]. Thus, he's attempting to destroy the Infinite Cycle by way of exterminating all life so that none will be left to succeed the current generation of Xel'Naga.]] Ironically enough, [[spoiler:his uplift of the Zerg to that end [[HoistByHisOwnPetard ultimately ends up biting him in the ass]] due to [[HeelFaceTurn Kerrigan]] [[RedemptionPromotion voluntarily accepting the essence of the last living Xel'Naga]] [[DeityOfHumanOrigin to become one herself and immediately smiting Amon down with her newfound power]] before moving on to continue the Infinite Cycle by herself]].

** In-game griefers can be this as well, reducing server populations on death-ban servers to ridiculously low numbers.

* ''VideoGame/{{Fallout}}'':

** Malos, the other Aegis and Pyra's/[[spoiler:Mythra's]] "[[CainAndAbel brother]]" wants to destroy all of Alrest initially because it seems like he thinks destruction is pretty fun. [[spoiler:While that was his initial self-aware motivation, in reality it's a combination of inheriting [[SinisterMinister Amalthus's]] own misanthropy and hatred for the world when he was first Awakened (which he internalized) and then, after realizing those impulses were from Amalthus and falling into something of an existential funk, developing his own personal hatred for the world over 500 years due to seeing [[CrapsackWorld the state of it]] and how it caused his best friend Jin so much undeserved suffering. And since Malos himself had a direct and indirect hand in all of that, [[DeathSeeker that just gives him a personal death wish]] on top of it.]]
** Malos's Driver, [[spoiler:Amalthus]], has a bad case of this as well. [[spoiler:After personally witnessing [[HumansAreBastards the worst of humanity]] (including running for his life from enemy soldiers only for his mother to sacrifice herself to save him and later finding her corpse, as well as having [[TheFarmerAndTheViper acts of kindness to others repaid with violence to others]]), he climbed the WorldTree intent on getting a direct audience and answer from [[TheMaker The Architect]] about why they live in a CrapsackWorld. What he found instead was LostTechnology in the form of war-machines, a lifeless [[ThePromisedLand Elysium]], and finally the Core Crystals of the Aegises, themselves capable of [[PersonOfMassDestruction destroying the world]]. At that point, he not only decided this meant the world was not just forsaken and [[PutThemAllOutOfTheirMisery deserved to be ended like a mistake]], the fact that The Architect never directly intervened to stop him convinced him that {{God}} was fully onboard with his intentions (he wasn't, [[AlienNonInterferenceClause but had long ago decided to never meddle with his creations again]] and let them do what they may).]]

** From ''Videogame/FinalFantasyXIV'', [[spoiler: Fandaniel]] wants to end all life on The Source and its Shards, including himself, in one giant paroxysm of pain and suffering, all while he gleefuly revels in the carnage and chaos he creates. This stands in stark contrast to the goals [[spoiler: of his fellow Ascians]], and serves to highlight how absolutely batshit insane he is.

* Mother from ''VideoGame/WildArms1'' believes destroying the worlds she visits is her destined role in the cosmos. [[spoiler: That includes Saturn Hiades, which Zeikfried thought was the demon homeworld. To make matters worse, Mother insists Zeikfried is destructive like her, to the point she is willing to [[DevourTheDragon devour and possess him]] to make sure he is.]]

* Many a ''VideoGame/BlazBlue'' villain has goals that involve killing virtually everyone:

** By the time of ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', Ganon has long degenerated into a barely sapient EldritchAbomination whose original motivation of world domination has decayed into world destruction.

* The BigBad of ''VideoGame/AmnesiaAMachineForPigs'' wants to exterminate all of humanity because [[spoiler:it's a fragment of the protagonist's consciousness that saw into the future and witnessed the various horrors of the 20th Century, such as the meatgrinder battles of UsefulNotes/WorldWarI, the UsefulNotes/AtomicBombingsOfHiroshimaAndNagasaki, and [[UsefulNotes/{{Cambodia}} the atrocities of the Khmer Rouge]], and then promptly decided on inflicting a twisted species-wide MercyKill on humanity. It's [[AxCrazy insane]] [[LargeHam ravings]] truly have to be heard to be believed.]]

*** Unlike many other examples of this trope, where these chracters represent pure destruction or chaos incarnate, The Flame of Frenzy is the representation of a philosophy. It's antinatalism incarnate, the belief which assigns a negative moral value to birth. The Frenzied Flame is the god of those who have suffered so much that they have come to believe that existence itself was a mistake. It's the very embodiment of the idea that life is not worth living, that the suffering and pain outweighs any positives, and that it would be better if all things simply ceased to be. Hyetta's own words actually paraphrase the core belief of antinatalism.

*** In it’s sequel, ''VideoGame/MarioPlusRabbidsSparksOfHope'', the Megabug’s reincarnation, [[BigBad Cursa]], attempts to destroy the universe by covering it in darkness.

* ''[[LightNovel/IsItWrongToTryToPickUpGirlsInADungeon DanMachi]]: VideoGame/MemoriaFreese'': In the ''LightNovel/DateALive'' crossover campaign ''Ais Catastrophe'', [[spoiler: not only is the Kaguya Yamai who appeared for most of the story revealed to be an impostor, she surpasses Isaac Westcott in this trope as she decided to become the ruler of all existence by tearing apart the multiverse and killing all gods in existence for [[ForTheEvulz nothing more than to experience the despair of all living things]]]].

* ''VideoGame/{{Minecraft}}'' brings us the Wither, which is essentially the ultimate griefer. It blows up everything in its path, and holds the philosophy that if something is alive, it must cease to be as such. [[ThatOneBoss It's very good at this, too]]. In-game griefers can be this as well, reducing server populations on death-ban servers to ridiculously low numbers.

* In ''VideoGame/Stellaris'', [[VillainProtagonist you can potentially become this]] if you choose to "Become The Crisis". The ultimate goal of this path is to construct the Aetherophasic Engine, which would allow everyone in your empire to AscendToAHigherPlaneOfExistence while killing everything else in the galaxy like the Zroni AbusivePrecursors [[VillainousLegacy attempted millennia ago]].

** The True Sith in the FanGame ''Knights of the Old Republic III: VideoGame/TheJediMasters'' worship the [[MonsterProgenitor D'arth Syyth]], a [[EldritchAbomination sentient manifestation of the]] DarkSide whose hosts that [[YouCannotGraspTheTrueForm manage to absorb it without going insane]] become compelled to drain all life, everywhere, like Nihilus & Vitiate.
