Omnicidal Maniac / Video Games

Omnicidal Maniacs in video games.

---

• Ledgermayne from AdventureQuest Worlds wants to end all life on Lore by sealing off all magic from it, knows said motivation of its own, and doesn't care if all life dies off if it succeeds.
  • Noxus also counts as one in the same game as well. The fact that he created Vordred with Sally's help was his first step towards turning all life on Lore undead. And that's not all - his attack on Shadowfall was also part of his plan to cause the end of the world by turning everyone undead.
  • Kezeroth the World Ender in the 2012 Frostval event, who wants to kill off all life on Lore by bringing Quetzal's Comet down upon Lore and awakening the great beast Quetzal. He is a Straw Nihilist who believes that he is an agent of nothingness and that the universe's true nature is decay and rot, that hope is a lie and that joy such as that experienced during Frostval is a mask that all life wears to hide from the truth.
• The Big Bad of Amnesia: A Machine for Pigs wants to exterminate all of humanity because 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 World War I, the Atomic Bombings of Hiroshima and Nagasaki, and the atrocities of the Khmer Rouge, and then promptly decided on inflicting a twisted species-wide Mercy Kill on humanity. Its insane ravings truly have to be heard to be believed.
• Ancient Domains of Mystery: The goal of the Chaos beings, who invade the realm from another dimension. Also, it is possible for the player to defeat the Chaos God, take his place, and do it by himself.
• Kerghan from Arcanum: Of Steamworks & Magick Obscura combines this with Well-Intentioned Extremist, seeing death as the natural state of existence, life as an abomination, and his plan to bring about the extinction of all beings as an act of mercy. The scary part is, he's right.
• Armored Core: For Answer has Old King. And you when siding with him. The reasons for it are never made clear, but siding with him means going straight for the very last habitats humanity has left and shooting them down one by one.
• In Baldur's Gate, followers of the God of Murder Bhaal are guaranteed to be this. Special mention goes to The Dark Urge in Baldur's Gate III, whose Evil Plan was to end all life, everywhere, and then his own in his father's name.
• The main villains of Bayonetta are this, as they all want to resurrect Jubileus, who wants to end the current state of existence.
• Big Bad Zachary Hale Comstock from Bioshock Infinite wants Columbia and by extension, Elizabeth, to recreate the Final Judgement on the 'Sodom Below.'
• Many a BlazBlue villain has goals that involve killing virtually everyone:
  • Hazama/Yuuki Terumi/Susano'o. He despises any lies that someone tells him, and what does he call the world? Lies! Lies! Lies! Considering his actions and lack of motives for said actions, the player can tell he's a psychopath that really does want to destroy everything. Although his true goal is to get back at the Master Unit (His sister Amaterasu) and the Real Big Bad Izanami even more so since she wants to create a world of death.
  • Mu-12/Noel Vermillion was this while she was Brainwashed and Crazy by Hazama. She wants to destroy the world and everybody in it. During her Astral she even rants about how corrupt and evil the world is and asks why her opponent resists. She sheds this attitude completely once she's freed from his influence, while also allowing Noel to use her full power once more.
  • Azrael goes around battlefields and destroys everything in his wake. This even earned him nicknames like "The Mad Dog", "King of Atrocity", and "Genocider".
  • Nu-13's never been the sanest individual but after perceiving Ragna's desire to save her as rejection, and discovering that her sister Mu-12/Noel cheated death like she did and is fully intent on stopping her, she now just wants to destroy everything.
  Kill...kill kill KILLKILLKILL! EVERYTHING MUST DIE! I'LL WIPE YOU OFF THE FACE OF THE EARTH! YOU'LL ALL DIE!
  • Izanami takes the cake out of all the series' examples. She wants to create a "world of death."
  Izanami: I seek a complete death... to erase every fragment, every trace of this wretched world... repeating itself over and over! That's why I needed the Embryo.
• You know you're living in what amounts to a crapsack universe when these are the kinds of guys in charge. Such is the cosmos in Lunar Knights, with the Immortals running around with their 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 what Dumas said has any weight to it, there are going to be a lot more on their way...
• Paulinus in Byteria Saga: Heroine Iysayana seeks to become powerful enough to kill all mortals. Justified as he is also revealed to be the artificially created Dragon-in-Chief of a superior being who couldn't do that himself without attracting the angels' attention. That entity has few problems with it because he fully knows about the afterlife, they'll all die eventually, anyway, and he doesn't understand why mortals exist in the first place. Which brings us to his motivation: He wants to bring the Celestial Bureaucracy down, and expects that killing all mortals will successfully make it collapse.
• The Qualia in Chaos Rings, a Planet Eater who has the ultimate goal of destroying spacetime itself.
• The Time Devourer from Chrono Cross 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.
• Requiem from City of Heroes plans to turn Earth into a homeworld for the Nictus. While that may not be enough to qualify him as an Omnicidal Maniac, you discover an alternate dimension where Requiem's plans have succeeded, and he's gone insane from being the only human left and is trying to destroy the entire multiverse.
• Mortimer McMire from the Commander Keen games. In the first game trilogy he attempts to destroy Earth because he considers the human race Too Dumb to Live. After that fails he decides to blow up the whole galaxy instead. And then it turns out that the galaxy destroying scheme was 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 eponymous Creeper of Creeper World subscribes to a philosophy summed up as "The Purity of Nothingness."
• Dark Souls:
  • Manus, Father of the Abyss, a Primordial Human that lost control of his Humanity and became an ape-like Eldritch Abomination whose sheer presence causes the Abyss to spread. By the time you fight him in the Artorias of the Abyss DLC, he has already sunk an entire town in the Abyss, mutate and madden the citizens into primal creatures and defeated Knight Artorias and corrupted him. Thankfully, the player character creates a Stable Time Loop by travelling to the past and defeating him before the Abyss can engulf the world.
  • The Children of Dark in Dark Souls II are women who are actually the physical embodiment of Manus' shattered soul who almost instinctively spread the Dark and seek power no matter the cost. The two that actually succeeded in their endeavors, Elana the Squallid Queen and Queen Nashandra of Drangleic left the kingdom they infiltrated in utter ruin through manipulation and corruption. Subverted for three out of the five Children of Dark known: Nadalia the Bride of Ash tried to infiltrate the kingdom of the Old Iron King, only to find it was already ruined, Alsanna the Silent Oracle fell in love with the Ivory King, and Karla who has no real interest in the whole "corrupt the land" deal, preferring to teach Sorceries than anything else.
• DanMachi: Memoria Freese: In the Date A Live crossover campaign Ais Catastrophe, 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 nothing more than to experience the despair of all living things.
• Blood Ravens Chapter Master and Big Bad Azariah Kyras in Dawn of War plans to slaughter ALL life in the galaxy in the name of Khorne. He specifically notes, in a malevolent Rousing Speech, that the greatest freedom of all is knowing they do this for no greater cause or meaning other than because Khorne would like it.
• The Vex and Hive from Destiny and their patron, The Darkness. The Vex are The Assimilator and mindlessly labor to convert all matter in the universe into Vex. The Hive obey a Religion of Evil that takes Social Darwinism to its furthest extremes. The Darkness, the cosmic manifestation of ruthlessness and selfishness, is fond of the Vex but more favors the Hive, but wouldn’t care much if either of them were destroyed; it’s here to make sure the universe continues to run on the law of kill-or-be-killed, and the destruction of its servants, unwitting or otherwise, would just be that in action.
• Disgaea:
  • Overlord Zenon from Disgaea 2 used to be an Omnicidal Maniac in his past, but has settled down with merely being an Evil Overlord ruling Veldime in his old age. Only he turns out to be a fake. When Laharl ends up unwittingly unleashing the true Zenon from her can, she immediately tries to go on an all-killing rampage until Adell and Rozalin manage to trap her again.
  • Nemo becomes one after Artina's death in Disgaea 4.
  • Disgaea 6 brings us Super Sage Misual, who has slammed through the Despair Event Horizon and into this trope after millions of attempts to save his lover, Releiza, and failing every single time.
• One of the playable characters in Dominion of Darkness - Destroyer of Life. Other types of Dark Lord want to dominate the world, he/she want to destroy it to end suffering which in his/her mind is inherent part of existence.
• The Darkspawn in Dragon Age were born to destroy the world of Thedas and everybody on it. The only reason they haven't is because they are also perfectly fine with attacking each other if there are no other victims. They are also compelled to seek out the Old Gods, an endeavor that usually takes centuries. Sadly, the Old Gods become tainted by the Darkspawn and become insane Archdemons that are also Omnicidal. The Archdemons are able to unite the Darkspawn and launch campaigns to wipe out Thedas known as Blights.
• The Mysterious Stranger in DragonFable seeks to merge the planet of Lore (and presumably the entire universe afterwards) with the Elemental Plane of Darkness, killing all life and permanently destroying all light in existence to make the universe a home for Darkness Elementals. He starts by devouring the sun.
• Upon hearing that Taiga in Duel Savior Destiny is incapable of remaking the world and can only destroy it, Big Bad Downy Reed is completely indifferent or even pleased, believing that a world that would kill his sister doesn't deserve to exist.
• Dwarf Fortress-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 Self-Imposed Challenge or two.
  • While there aren't really any elaborate plots to carry it out, anything with the tag [OPPOSED_TO_LIFE] will do its best to slaughter anything that dares so much as exist in its presence that doesn't have the tag, or be destroyed in the attempt. Most often seen in The Undead.
• Elden Ring:
  • The Loathsome Dung Eater is hated and feared by all with good reason. A Serial Killer who spreads the Seedbed curse by torturing, mutilating, and defiling his victims with the Curse, keeping them from returning to the Erdtree and reincarnating, forced to remain as tormented wandering souls forever, never able to find peace or be reborn as the Humanoid Abomination race known as the Omen. Having done this to thousands of others, the Dung Eater's goal is to spread the curse to the reforged Elden Ring and damn the entire world. The Player Character can potentially become one and help the lunatic do it.
  • The Flame of Frenzy is an Outer God that views life itself, in its current state anyway, as an abomination. According to one of its adherents, there was originally only one living being called the One Great, but the Greater Will (the god currently in charge of the world) accidentally goofed up somehow, resulting in other forms of life spawning from the One Great. The Flame of Frenzy therefore seeks to correct this screw-up by burning the entire world and melting everything until all is one again. And yes, just like the Dung Eater, you can become its chosen champion and help it achieve its goal.
    • The most horrifying thing about the Flame of Frenzy is that it also inflicts this on its followers. It was summoned into this world by the collective prayers of thousands of innocent people persecuted by the Golden Order, locked down in the darkest depth to die in the dark. Their cries of hope and salvation falling on deaf ears, the horrible victims of this genocide were pushed into a collective Despair Event Horizon, begging for the world to simply be destroyed.
    Hyetta: Those who gave me grapes howled without words. Saying they wished they were never born. Become their lord. Take their torment, despair. Their affliction. Every sin, every curse. And melt it all away. As the Lord of Chaos. No more fractures...no more birth...
    • 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 Efilism incarnate, the belief which assigns a negative moral value to life. 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 joy, and that it would be better if all things simply ceased to be. Hyetta's own words actually paraphrase the core belief of Efilism.
• The Elder Scrolls
  • Mehrunes Dagon, the Daedric Prince of Destruction. His very sphere of influence is to destroy. Everything. He has repeatedly attempted to take over Mundus, the mortal plane, with the goal of destroying it completely.
  • Alduin, the draconic Beast of the Apocalypse, has the title "World-Eater" for a reason. It is his divinely mandated duty to "eat the world" at the end of every "kalpa" (cycle of time) so that it can be remade anew. Though depending on your interpretation of the mythology, he may or not fit the 'maniac' part of this trope as his destroying the world is actually a regulated process. However, as Mehunres Dagon learned in The Seven Fights of the Aldudaga, Alduin gets absolutely livid if you interfere with the process.
  • The Thalmor are an Altmeri (High Elf) sect of religious extremists. They play up the old Altmeri religious belief that the creation of the mortal world (Mundus) was a cruel trick played on their divine ancestors, which forced them to experience suffering and death. They believe that if they can unmake Mundus, it will return them to a state of pre-creation divinity. Unfortunately, the very idea of Men inherently stabilizes the Mundus, and erasing this idea requires eliminating the deity Talos. By banning his worship, they are hoping to weaken and eventually eliminate him, allowing them to act on their plans to unmake the world.
• Endless Legend has the Cult of The Eternal end, an entire civilization of Omnicidal Maniacs. Their followers vary, but the leadership in paper just wishes to take revenge on their neglectful creators, the Endless, by wiping out their every trace; in practice, since the Endless got involved in just about everything, their vengeance would take out most life in the galaxy.
• 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.
• Sir Yeti in E.V.O.: Search for Eden's first line is, "Destroy the creatures! Destroy! That is my destiny." Survival of the Fittest, the game's theme, taken up to eleven.
• Fallout:
  • The Enclave in Fallout 2 sought to kill everyone other than themselves with a genocide virus, despite the fact that a lack of genetic diversity would have ensured their own death eventually. Much of the point of the game is that the Enclave is so consumed by Honor Before Reason that they don't care if humankind dies out. They would rather no one survive than their United States die, denying the fact that it already has. In Fallout 3 they've moved past this delusion, with the exception of their AI President Evil.
  • The Player Character in Fallout 3 can potentially become this, as much of the game's evil options amount to causing wanton genocide for no perceivable reason other than watching the world burn.
  • The Toaster in Fallout: New Vegas: Old World Blues, who also happens to be a Harmless Villain due to being, well, a sentient toaster (which he himself claims is also his excuse for becoming so murderously insane in the first place).
  • Father Elijah and Ulysses from the New Vegas expansions Dead Money and Lonesome Road. Elijah wants to conquer and enslave the Wasteland with technology from the Sierra Madre, while Ulysses feels there hasn't been enough atomic holocaust. You can, however, convince Ulysses that his motivation and goal are flawed right after it has been set in motion, and actually help you out to try and stop it. No such option for Father Elijah, however.
• Fate/Grand Order:
  • Professor James Moriarty from Sherlock Holmes is an Archer class Servant. He's eventually revealed to be willing to destroy the planet not because he hates humanity or the like, but because he wants to one up every criminal in history as his "Perfect Crime". His plan in Shinjuku is to do it by summoning an asteroid to Colony Drop the planet, and he's only stopped because the method by which he chose to do this, to even his own surprise, ended up making him care too much about the protagonist and caused him to hold back in the final fight at the eleventh hour, dooming his plan.
  • In the Gotterdammerung chapter of Cosmos in the Lostbelt, Surtr, King of the Fire Giants, is one of these, as per his role in Norse Mythology. He nearly hit the Despair Event Horizon when he failed to finish Ragnarok in this Alternate Timeline before becoming Sealed Evil in a Can, and when he's properly freed he immediately sets out to grow strong enough that he won't just finish burning this Alternate Timeline to ash, but will move on to all the others. And the funny thing is, his major motivation for the upswing in goals is because he thinks such devastation is the best way to win the heart of Ophelia Phamrsolone, who comforted him on his failure while he was imprisoned and caused him to fall in love with her.
• In Fate/stay night, Angra Mainyu is a perfect Omnicidal Maniac, who took on the Servant form of Avenger in the third war. What's that, Avenger died and got absorbed into the omnipotent, wish-granting holy grail, giving him access to an unlimited source of miracles and magic, and the ability to swallow the planet in Black Mud whenever the Grail is used to perform a miracle? Well...fuck.
• Final Fantasy is big into this. In order:
  • Chaos, who came into existence thanks to the Fiends, who were already destroying the world to begin with.
  • Xande is pissed about being made mortal and wants to put everything into suspended animation, forever. Cloud of Darkness, a personification of the Void, wants to reduce everything in both worlds to nothingness.
  • Zemus wants to exterminate all human life on Earth so that he (and the other Lunarians, maybe) can rule. Zeromus is just evil, or at least the evil and hatred needed for that desire given form. Or something.
  • Exdeath is an arbormorphic personification of evil. Neo Exdeath, a personification of the Void, wants to reduce everything (including itself) to nothing... wait...
    • This was touched upon in Dissidia Final Fantasy. Cloud of Darkness's "Void" is the destruction of everything, leaving nothing. Exdeath's "Void" is the return of everything to its original state, the realm of the Void. Cloud = Empty universes (AH Class X5), Exdeath = No universes (AH Class Z).
  • Kefka, was already quite insane, but just got worse due to the power he acquired from the Statues of the Warring Triad. When the Heroes reveal that despite the fact that Kefka has caused The End of the World as We Know It they still harbour hopes for the future, he decides to destroy reality and "create a monument to nonexistence."
    • His pre-fight quote against Exdeath in Dissidia: "Destruction without death? BORING!"
  • Final Fantasy VII has not one, but two, the Big Bad Sephiroth and his father, Professor Hojo.
    • For Sephiroth, after he went to the town of Nibelheim, he learned the truth about his origins and it drove Sephiroth mad. Enraged, he attacked and destroyed Nibelheim only to be stopped by Cloud Strife. But he didn’t die, rather, he fell into the Lifestream, gained its knowledge and he decides absorb the planets lifestream to become a god and turn the planet into his vessel. In Advent Children he is resurrected via possessing his remnant Kadaj and plans to continue his goals of making the planet as his vessel, but is ultimately defeated again and tells Cloud that he will never be a memory, implying that he will continue to exist within the lifestream.
    • For Hojo, he was the one who created Sephiroth in the first place (both naturally, and artifically, due to being his birth father and injecting him with Jenova's cells while he was still a fetus, respectively) and he monitors almost all of Sephiroth’s actions for the sake of seeing his research prove successful, which is implied to result in the total destruction of the planet, or at least severe damage. It's not even the last time Hojo attempts to do this either, as Dirge of Cerberus revealed that he ended up possessing Weiss the Immaculate's body with the intention of tricking the Omega WEAPON, a WEAPON that activates when the end of the world arrives and leaves the planet, into awakening, and it is heavily implied that destroying the world was indeed his intention that time as well.
  • Ultimecia wants to compress time into a Timey-Wimey Ball so she can recreate the entire universe because she's pissed off about centuries of oppression against her kind. Even though she has a Freudian Excuse it is hardly valid, since these centuries of oppression were really set off when she went back to the time of the story, and pissed everyone off.
  • Kuja freaks out upon discovering that he is mortal, and thus will eventually die and decides to pull a Taking You with Me on the world to ensure it doesn’t outlive him.
  • Seymour thinks that life is nothing but suffering, and that the only way of escaping Sin, the cause of it is that everyone should die.
  • Shuyin was subjected to Mind Rape for a thousand years, so he decides to destroy the world out of anger that it let him and his lover die.
  • Kam'lanaut and Eald'narche trying to "Open the Gates to Paradise". Which would just have the side effect of killing every non-avatar and non-Zilart on Vana'diel. Promathia wants to release the Emptiness on Vana'diel killing everything so he can finally die.
  • Galeth wants to destroy all life on Cocoon and Orphan, the fal'Cie who rules over it. Orphan himself just wants to destroy everything.
  • Caius wants to destroy Etro, the goddess of time and death, in order to save Yeul from a Vicious Cycle of early death and reincarnation. Problem is, Etro's death will cause a Time Crash in which a wave of primordial chaos washes over the world and eventually reduces it (and all of its inhabitants) to nothingness. Caius thinks that this is an acceptable sacrifice to make.
  • From Final Fantasy XIV, 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 of his fellow Ascians, and serves to highlight how absolutely batshit insane he is. There's also 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.
  • Chaos (again) chooses to destroy the world and himself, after finding that a world without Cosmos was a much emptier existence than he thought it would be.
  • Dissidia actually has the "take over the world" villains conspiring against the "destroy the world" villains on their team. The take-over-the-world villains wanted Sephiroth, but he really doesn't care one way or another because he's obsessed with fighting Cloud.
• Forever Home has Barclyss and Kail, who want to end all life on the planet for different reasons. Barclyss wants omnicide because he tried and failed to see any value in living while Kail wants to have the planet to himself, for no given reason at all. Their plan to accomplish this is to use a spacecraft to launch explosive Cosmite shards at the planet's surface, causing the fantasy equivalent of nuclear winter.
• The Shivans from the Descent: Freespace series are a 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 Ominous Latin Chanting), 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 Ancient information was later discovered by Vasudan scientists giving the Terrans and Vasudans just enough time to save their collective arses. But not before 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 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. Even their own ships that seem to have suffered engine failure after emitting the triggering energy pulse and all those ships still in battle with the GTVA. And to heck with collateral damage from the supernova.
  • In both games, there are speculations from all sides as to why the Shivans seem so 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 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 (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. Nobody will ever know, either, as the original publisher is bankrupt.
• Deathborn of F-Zero wants to become a galaxy-destroying god. Why? For the Evulz, that's why.
• Half-Minute Hero's main game mode, "Hero 30", reduces this type of villain to a Monster of the Week and uses them as the boss of every single level, all of them seeking the destruction of the planet for reasons that vary from genuine nihilism to a Giant Enemy Crab upset about not being able to walk forwards.
• Halo:
  • While the Covenant only want to activate the Halos because they believe they are divine instruments to propel them to godhood, the High Prophet of Truth finds out that they are actually galactic-scale weapons created to destroy all life in the universe (as a final failsafe against the Flood). Nonetheless, Truth resolves to fire them anyways, with the motive behind this possibly being that he is fine if he doesn't achieve divinity as long as he can maintain his power as leader of the Covenant. He may even believe that activating the Halos will allow him to transcend anyways.
  • As a follower of the Mantle, the Ur-Didact originally held fast to the belief that, as a Forerunner (and a Warrior-Servant), he should protect both other species and his own, while having proper respect and admiration for worthy examples of the former (such as humanity). After a rather unhealthy conversation with a Gravemind (i.e. one of his "gods"), he developed a different stance; if it's capable of threatening the Forerunners in any way, it's got to go; this includes humanity. Luckily, he took two shots to the chest and was locked in a Cryptum before he could put his plan into action. Unluckily, he was accidentally allowed to escape 100,000 years later, and while his initial attempt to enslave humanity as an AI army was thwarted, even the loss of his original body won't necessarily stop him from trying it again.
  • The Precursors might count as well. Maybe. They operate under an extremely incomprehensible thought process. On the one hand, one stated they intend mainly just to cause eternal torment and suffering for the denizens of the galaxy. On the other, their most recognizable agent is a Hive Mind plague that assimilates entire species into massive mounds of flesh.
• Hatred has the Antagonist, who wants to go on a genocide crusade because he believes that humans are all maggots feeding on the corpse of the world.
• Horizon Zero Dawn: HADES seeks to wipe out all life on Earth, just as it was programmed. It was intended as a failsafe; if GAIA accidentally created an environment unsuitable for human life, HADES would "take the wheel" and use her systems to un-terraform the Earth back to zero so that she could try again. Some sort of alien signal caused it to activate unnecessarily, and now it is trying to wipe out everything despite the fact that the world is completely livable for humans.
• In House of the Dead, 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." They sound the same for good reason, as the Wheel of Fate is none other than Dr. Curien, Magician's creator.
• In Hyperdimension Neptunia, Arfoire seeks to destroy the world by spreading piracy. From there, she can get her godhood back.
• Lazarus in I Miss the Sunrise...possibly. He's a mentally unstable Blood Knight, and characters claim that he would annihilate everything in the galaxy For the Evulz if he had the chance, but when you do meet him, he claims that such things are beneath him. Given what the Big Bad's plan is, though, it's possible that he wants to permanently destroy all of reality by ascending to godhood and then preventing the new universe from being born.
• Impossible Mission: Professor Elvin Atombender, a Mad Scientist who is attempting to hack the world's nuclear missile codes and destroy the planet.
• According to Kessler, The Beast from inFAMOUS.
• The first Jak and Daxter game gave us Gol and Maia, who wanted to unleash Dark Eco upon the world. The third game's Big Bad also fits this trope, teaming up with the Dark Makers to wipe out the universe.
• Kingdom Hearts
  • Ansem, Seeker of Darkness, the Big Bad of Kingdom Hearts wants The Heartless to destroy everything, since he believes darkness is the natural state of things. He first tries to accomplish this by gathering the seven Princesses and opening the Final Keyhole, and then by opening the Door to Darkness and unleashing hordes of them.
  • It gets even better: Kingdom Hearts: Birth by Sleep reveals that that Omnicidal Maniac is just a fragment of an even worse one. His goal? Trigger Armageddon, watch from the front row and see what happens next.
  • The franchise's take on a few Disney Villains, namely Jafar, the Master Control Program, and Hans, makes them hell-bent on destroying their worlds.
    • Jafar manages to find the Keyhole for Agrabah, but it's sealed before he could summon the Heartless. When he returns in Kingdom Hearts II, his mind has snapped to the point where he'll proclaim he'll destroy the universe.
    • The MCP finds a self-destruct program for Radiant Garden, and decides to see what can happen if activated. A few weeks later, he manages to hack Cid's computer to take control of the town's defense claymores and sends digital Heartless to wage war on organic life forms.
    • In Kingdom Hearts III Hans' failure to kill Elsa from Anna's Heroic Sacrifice causes him to become Sköll, a Reality Warper Elite Heartless that eats light. His goal is to destroy all light in both Arendelle and the universe following the sisters ascending as New Lights. And unlike in the film, this gets him a death sentence, courtesy of Sora and Marshmallow.
• In Kirby: Planet Robobot, the Mother Computer of the Haltmann Works Company, Star Dream, comes to the conclusion that in order to ensure that the HWC is profitable and prosperous that it should destroy all organic life, as it deems them inefficient and against order. It should be noted that this is a computer with access to an array of reality-warping powers, and which later fuses with the HWC's mothership which is then revealed to be a wish-granting mechanical celestial object on the same levels of Galactic Nova; a Physical God. It should also be noted this is all from a Kirby game.
  • In Kirby's Return to Dream Land Deluxe, the Master Crown is revealed to be this. It's a sentient Artifact of Doom that greatly magnifies its wearer's power, but also strengthens the darkness in their hearts. Eventually, the crown eats its victim's soul, leaving them an Empty Shell channeling the crown's one desire: to destroy.
  • In Kirby and the Forgotten Land, Fecto Elfilis is revealed to have attacked the titular planet in the distant past for absolutely no reason other than to wipe out all life on the planet. What's more, when you face it as the Final Boss, its ultimate attack, where it summons meteors to drop on Kirby, is called "The Fermi Paradox's Answer", implying that the reason people can't talk to alien lifeforms is because in Fecto's case, its response to contact is to wipe them out.
• Lord Ghadius of Klonoa: Door to Phantomile, a living nightmare who has gathered so much resentment from the way the world's dreamers have rejected him (since no one wants to have nightmares), he's decided they don't matter, and they can go straight to hell. His quote on the quote page is rather chilling in its simplicity.
• League of Legends: Nocturne would like nothing better than to hunt down every last being on Valoran, Summoners in particular, and kill them in their sleep. Simply because he finds life as we know it disgusting and offensive.
  Nocturne: People are flames to be blotted out!
• Avalon from Legaia II: Duel Saga attempts to use the power of the Source Forge, the beacon of creation, to destroy the world and create a new one in his image.
  Avalon: I will destroy all life, leaving only me! I will be the world!
• The Legend of Zelda:
  • The Legend of Zelda: Majora's Mask: Clearly, any demon trapped inside a mask who wants to completely destroy the world by crashing the moon into the Earth can't be sane.
  "I...I shall consume. Consume...Consume everything."
  • In the The Legend of Zelda: Oracle Games, Ganon was resurrected into this instead of his usual intelligent self due to an improper sacrifice of his evil surrogate mothers.
  • The Legend of Zelda: Tears of the Kingdom: Demon King Ganondorf not only plans to rule the world, but completely remake it in his own image. His method? Create an army of demons and eliminate everyone in the kingdom, explicitly stating to leave no survivors. Even after Ganondorf is sealed away, this omnicidal mindset endures through Calamity Ganon from The Legend of Zelda: Breath of the Wild, a mindless manifestation of Ganondorf's raw hatred and malice given form.
• The Big Bad of Live A Live, 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 Start of Darkness.
• The Cosmic Horror that is the W'rkncacnter in the Marathon series. Little is known of them as to why, but it'd seem their mere existence disagrees with reality itself so much just being around unravels it, and prefer not to be imprisoned where they won't do harm.
• The Marvel vs. Capcom series has the final bosses Onslaught, Abyss and Galactus.
  • Marvel vs. Capcom: Infinite gives us Ultron-Sigma. Because what would you expect when two Kill All Humans villains perform a Fusion Dance?
• Mastermind: World Conqueror puts you in the role of The Mastermind, whose goal is to destroy the Earth. He borders along Mike Nelson, Destroyer of Worlds because he equates destroying as conquering.
• Dr. Weil/Dr. Vile of the Mega Man Zero series. This is the only kind of Big Bad you could find in the darkest period in Mega Man history. He starts off as an ambitious scientist, who sees Reploids as mere tools instead of actual sentient beings, and was getting tired of the constant Robot Wars that they wage against humankind. When a cure was finally made (the Mother Elf) to rid the world of The Virus that started the war in the first place, Weil Brainwashed it to become his tool for destruction, and initiated the Elf Wars, where, in the span of only 4 years, a large portion of the human and Reploid populations (60 and 90%, respectively) were wiped out. After that war, he is sentenced to immortality, where his consciousness was transferred to a self-regenerating armor, and then sent to forever exile on the barren wasteland that he created. When he comes back he makes sure that the humans suffer the same way he did, or worse. And when humans start to rebel and flee from his reign of terror, and his general turns on him, he becomes much worse, setting a Colony Drop to Area Zero, the very last hope of restoring the dying Earth, along with the human refugees settling there! Only through Zero's efforts was he stopped in time, and Zero makes his last hurrah, and Weil, whilst defeated, remained alive thanks to his curse. And he still continues to plague the world over and over...
• Hot Coldman from Metal Gear Solid: Peace Walker turned into one when he activated Peace Walker to not only launch a nuke at Cuba [originally Mother Base, but it was changed by one of his men], but also to transmit the false data to NORAD, and made it quite clear that, even though he hopes that they don't launch due to his feeling that this will prove that humanity is weak-willed, he did not care either way.
• 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.
• Minecraft:
  • The Wither 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. It's very good at this, too. Not even the Warden (see below) is exempt from this rule.
  • The Warden may be a fully blind mob, but if it detects a mob or a player with its keen senses of hearing and smell (or if that mob/player attacks it), it will completely and totally annihilate it, regardless of what it is. And yes, it will even go after the Wither.
  • Give a Vindicator the name "Johnny" via the use of a name tag, and it will turn its axe on everything that isn't another Illager.
  • If a Hoglin transforms into a Zoglin, it will attack damn near any entity it sees, except Creepers and other Zoglins. Even the Wither, the Warden, and armor stands are fair game.
• Shinnok in Mortal Kombat intends to become The Omnipotent by consuming all energies in the Multi Verse including the life forces of all living things. Except Quan-Chi, who will be spared as a "reward" for serving Shinnok. In The Bad Guy Wins endings, Quan-Chi reveals that he has outplayed Shinnok and manages to steal his power — and uses it to become one of these himself, except this time he simply elects to kill For the Evulz.
  • Villains like Shao Kahn and Onaga are out not to destroy the realms but to conquer them and rule them as tyrants forever - their favored tactic is to merge the other realms with Outworld, the realm they rule (after they get rid of each other). However, Mortal Kombat: Deception reveals that they and other villains are the Unwitting Pawns of The One Being, the sentient entity that in ancient times tried to eat the Elder Gods before they defeated it and turned it into the realms (The Heavens and the Netherealm excepted). Essentially, the One Being is trying to get them to resurrect itself by merging the realms and likely end all life in said realms in the process — if Onaga had been playable, his ending would have seen him become the One Being. This is probably an Aborted Arc though, as subsequent games never mentioned the One Being again.
    • Shinnok's arcade ending in Mortal Kombat X reveals the fallen Elder God wanted to obtain his Rage Against the Heavens by merging all the realms into the One Being, which then devours the Elder Gods and results in a Class Z Apocalypse How. It's shown that the One Being was behind Shinnok's ambitions to merge the realms, just as it did with Shao Kahn and Onaga in the past.
  • Scorpion briefly became one of these in Mortal Kombat: Armageddon to get revenge on the Elder Gods in a Rage Against the Heavens scheme after they fulfilled a promise to bring his dead clan back to life... and brought them back as undead zombies. The plot of that game was that there were too many powerful fighters running around and the gods had decided to pit them against each other in a tournament with ultimate power as the prize, because otherwise the fighters would unintentionally destroy everything with their fighting. Scorpion tried to derail the plan by killing The Chosen One, the guy who was supposed to get the power to prevent it landing in the hands of one of the villains which the next game reveals happened anyway — Shao Kahn was the winner, simply because he was pissed at them. He wanted to destroy all the realms to spite the Elder Gods, and if he could, kill them too in the process.
  • It turns out that the reason Outworld's rulers have a tendency to become expansionists trying to take over other Realms is because Outworld is the Realm that houses the largest fraction of the One Being's essence. As a result, the One Being's influence is most keenly felt in Outworld.
• Porky in Mother 3. He wants to destroy the entire world, because he's gone even more insane as a result of the Time Abyss he went through, and that still nobody loves him. Slightly different from the usual in that the world HAS already been destroyed - perhaps even by Porky - and that these people are the last remaining survivors. And yet he feels it's not enough, because he wants to stand alone in a world where everyone that doesn't like him is gone.
• Neverwinter Nights 2: The King of Shadows. He was initially created by an ancient empire to protect it from evil forces. There are a series of flukes that turns him evil after the people that made him died off. With nothing left to protect, The King of Shadows goes berserk and decides that the entirety of the Forgotten Realms is responsible for the empire's collapse. He naturally comes to the conclusion that the whole world needs to be destroyed in retaliation.
  • Akachi the Betrayer in the expansion was cursed by the now-dead god of death, Myrkul. A Horror Hunger has consumed him, leaving him an empty shell with an insatiable need to devour the spirits around him. If left unchecked the curse could devour planes. This is the evil ending of the game. The Player Character can do exactly that, utterly annihilating several gods in an epic battle. It is an example of just how powerful the Spirit-Eater curse is.
• In The New Order: Last Days of Europe, Heinrich Himmler actively wants a global nuclear apocalypse because he believes it will pave the way for the Aryan Master Race to recolonize the world, since only the Master Race could survive such a thing (and he hides survivors of them in nuclear bunkers in the Alps just in case). His focus trees for Ordenstaat Burgundy inevitably end up leading to touching off the thermonuclear war.
• OFF: The Batter is a successful example of this trope, depending on which ending you pick. Even if you decide to side with The Judge in the Last-Second Ending Choice, all that remains of the universe is the empty zones, but even so, The Judge says that he prefers a blank, lifeless world to The Batter winning by turning the switch to "off" and wiping everything out of existence. Of course, The Batter himself appears to see it as a Mercy Kill upon a world gone off the rails; a creation so neglected and gone so wrong all that's left to do is put it down and move on to nothing.
• The Walrider in Outlast, at least while Billy Hope was controlling it (minus Dr. Wernicke). Once Miles becomes the host, it's implied that he only wishes to use its power to kill the bastards that created it in the first place.
• Persona:
  • In Persona 2, Nyarlathotep's end goal is to drive humanity to total self-destruction, obliterating all life... so he can win a meaningless bet.
  • From Persona 3, both Shuji Ikutsuki and Takaya express an interest in destroying all life. The former seems to be under the impression that he will be spared and given the chance to remake the world in his image after Nyx destroys it, while the latter is already dying and just wants to see everything else go first.
  • Big Bad Adachi in Persona 4 was driven to becoming a Straw Nihilist and came to the conclusion that all life is troublesome and pointless, and thus people would be better off living as Shadows. The goddess Izanami is following Adachi's goal of turning everyone into Shadows, as that is what she believes humanity desires.
• Coaxmetal from Planescape: Torment. A very unconventional application of this trope, he is an iron golem who's the Ultimate Blacksmith, but also believes that entropy, decay and destruction are necessary. You can unleash him from his prison to rain destruction to the local Modrons, but otherwise his brand of philosophy will actually help you in confronting the Big Bad in the finale.
  I AM IRON GIVEN PURPOSE. I FORGE THE WEAPONS BY WHICH THE MULTIVERSE WILL BE UNMADE.
• Pokémon:
  • In Pokémon Diamond and Pearl / Platinum, Team Galactic Boss Cyrus wants to use the time-and-space bending powers of Dialga and Palkia to destroy the current universe and build a new one in his image, i.e. without any emotion whatsoever.
  • Darkrai from the Pokémon Mystery Dungeon games.
  • Team Flare Boss Lysandre in X and Y. His plan is to ensure enough resources for all people on Earth...by killing most Pokemon and humans.
• Big Bad Heiss from Radiant Historia. After seeing history full of warfare, suffering, and sacrifices (which only seem to delay the inevitable destruction) through the Black Chronicle, he decides that people do not deserve to exist and tries to bring about The End of the World as We Know It.
• Regulos in Rift is...well, imagine the bastard child of Unicron and 682 on steroids: He'd like nothing better than to grind the universe to dust and lap it up. In Terminus, he's strongly implied to succeed, although some Defiant Ascended go back in time and prevent it.
• The Destroyer from Romancing SaGa 3.
• 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.
  "Now open your eyes and see! I am no mere Marduk. My names are countless. My age beyond reckoning. I am the embodiment of all creation's ills, and my purpose is but a simple one: To annihilate all that is unworthy. All that is a reflection of myself."
• In Sands of Destruction, there is a Committee whose goal it is to Destroy the World.
• Satellite Reign: In the ending, your sponsors steal the satellite control codes you spent the entire game fighting for, giving them world domination. But the first thing they do with the satellites that control immortality and mind control the entire world? Crash them straight into every capital, permanently killing almost everyone. All seemingly because the Crapsack World they live in is so bad they've gone to believe destroying the whole thing and starting over with whoever survives is better.
• Shadowverse: Unlike Nexus who destroys and remakes worlds, Nerva outright annihilates them.
• After breaking his way out of Hell during the events of Sengoku Basara 3, this becomes Oda Nobunaga's new shtick. This is only a slight step-up in nastiness from how he was when alive.
• In the opening of Shin Megami Tensei III: Nocturne Hikawa succeeds in bringing about the Conception that destroys the world (although the one who does the actual destruction is YHWH, who intends to have the world recreated afterwards through a Reason). He further intends to turn this new world into a World of Silence through the Reason of Shijima. In the True Demon ending the Demi-Fiend destroys all of Creation on Lucifer's orders.
  • Shin Megami Tensei IV gives us The White, ancient human spirits who learned of the extent of the Great Will's machinations to try to get the perfect World of Silence eons ago, broke down on seeing that even a successful removal of God wouldn't save humanity from spirit-borne ruin, and decided that the only true cure was to effectively create a black hole powerful enough to reverse the Big Bang.
  • Shin Megami Tensei IV: Apocalypse ups the anti once again with Dagda. Similar to the White he hates how the universe is trapped and confined by the will of YHVH and the futility of trying to change the cyclical nature of reality, however unlike the White who are doomed to fail by virtue of only erasing one reality out of infinite, Dagda acts on a much larger scale: humans, demons, angels, and even YHVH himself won't be erased, they will be killed so that the foundation of reality can be uprooted. He won't be content until there is nothing left of the old reality, all he needs is a Godslayer to execute them.
• After Galcian dies in Skies of Arcadia, Ramirez goes insane and shoots for the destruction of the entire world, stating that it is no longer worthy of living. 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 the Silvite Elders, who had the same goal but lacked the means.
• While they don't seek to destroy all life forever Nero, Blanck, and Baion from Solatorobo all want to kill off the planets current civilization of Caninu and Felineko. While Nero and Blanck seem to want to destroy just because they were created to, Baion believes he's justified in killing everyone. Having seen the Human race wipe itself out in global warfare, he believes the Caninu and Felineko are going down the exact same path. Rather than let Earth get blown up again he seeks to restart life with a new perfect race once everyone else is dead.
• Sonic the Hedgehog:
  • Shadow was this when he first appeared in Sonic Adventure 2 this is because Gerald Robotnik had reprogrammed him into destroying the world with the Space Colony ARK as an act of revenge for the death of Maria which made him lose his sanity.
    • He becomes this again in his spin-off game. In the Pure Dark - Dark ending, Shadow collects the Chaos Emeralds and decides to bring order and justice to humanity by destroying the entire world.
  • Solaris in all his insanity attempts a class Z.
  • Chaos intends to do this in Sonic Adventure once he reached his Perfect form, he also wiped out a civilization in the past, and would have likely continued had he not been sealed away by Tikal. It's noted in other games he's not always like this, but his interaction with the Chaos Emeralds can sometimes drive him mad enough with fury he just starts destroying things and doesn't stop.
  • Infinite attempts to do this by making a virtual sun using the Phantom Ruby and dropping it on the Earth, where Eggman will create a new Eggman Empire.
  • The End attempts to destroy Sonic's planet, and already succeeded with several planets and stars before this, including The Ancient's homeworld. It would've destroyed the universe or all of existence if it wasn't stopped. It's unclear why it does this other than for the sheer hell of it, but some of its rants hint at it seeing itself as an enforcer of Order in a universe where even being alive counts as Chaos.
• Gig from Soul Nomad & the World Eaters fits this trope to a T... And he's on your side.
  • There's also Revya him/herself in the Demon Path, who ends up unmaking existence in the 'bad' ending.
• The Ruin, Big Bad of Starbound, is a planet-sized Eldritch Abomination that finds all life repulsive and wants to annihilate everything that lives, usually on a planetary scale. Its Dragon, Asra Nox, has a similar mindset towards all non-human sentient life due to a traumatic experience during her childhood.
• Star Control 2: "We are the Ur-Quan Kohr-Ah. We cleanse our destiny. You will soon die. Make whatever rituals are necessary for your species."
  • The Kohr-Ah are an interesting take on the concept: they do not, believe it or not, hate other species, no do they find other species disgusting. No, their whole motivation for being Omnicidal Maniacs is they're terrified of other species... or, more specifically, terrified of another species growing powerful enough to enslave them. This stems from the horrific mind-controlled enslavement their race suffered at the hands of the Dnyarri. They see wiping out all other forms of life as the safest way to ensure this never happens again. Indeed, if you can get them to talk to you for a while instead of attacking, they're remarkably pleasant and polite... as pleasant a conversationalist as a giant black centipede in a death-dealing war machine can be, anyway.
• 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. 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, creating a new generation of Xel'Naga and starting the Infinite Cycle anew. However, as the Xel'Naga refuse to interfere with the development of their successor races, 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, 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, his uplift of the Zerg to that end ultimately ends up biting him in the ass due to Kerrigan voluntarily accepting the essence of the last living Xel'Naga to become one herself and immediately smiting Amon down with her newfound power before moving on to continue the Infinite Cycle by herself.
• Star Ocean series:
  • While nine of the Ten Wise Men in The Second Story merely seek to take over the universe, the last one, Indalecio / Gabriel, seeks to invoke the Crest (Symbol) of Annihilation to destroy the universe. If you complete some optional sidequests to learn more of the backstory, Indalecio/Gabriel is revealed to be Dr. Lantis, who went on a crazed rampage after losing his daughter Filia/Philia to a great war hundreds of millions of years ago
  • Luther Lansfeld from Till the End of Time becomes one late in the game. He does manage to destroy the Earth and many other planets, but decides to destroy the entire universe later on.
  • In Star Ocean: The Last Hope, Faize becomes one by the end of the game.
• Star Wars: Knights of the Old Republic:
  • Darth Nihilus of Knights of the Old Republic II: The Sith Lords. At some point in the past, he began consuming the lives of others for his nourishment by draining them through the Force. By the time the player character encounters him, he has become, essentially, the Anthropomorphic Personification of hunger, has already consumed all life on several inhabited planets, and, if left unchecked, will soon do the same to the entire galaxy... and beyond.
  • His master, Darth Traya, sought to kill the Force itself. In defiance of the trope, it turned out, once she realized that the Force does not equal life and that people would survive without it and the Jedi/Sith that depended on it in spite of the World of Silence this would create.
  • The Sith Emperor Darth Vitiate in Star Wars: The Old Republic drained all life from his home planet 1300 years before the game started, and intends to repeat it on a galactic scale. Doing this to one planet rendered him more or less immortal, but if he successfully enacted a galaxy-wide version of the ritual he would essentially become the Force.
  • The True Sith in the Fan Game Knights of the Old Republic III: The Jedi Masters worship the D'arth Syyth, a sentient manifestation of The Dark Side whose hosts that manage to absorb it without going insane become compelled to drain all life, everywhere, like Nihilus & Vitiate.
• In Stellaris, 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 Ascend to a Higher Plane of Existence while killing everything else in the galaxy like the Zroni Abusive Precursors attempted millennia ago.
• Prince Luca Blight from Suikoden II is a combination of this trope and total Ax-Crazy. He's a very unpleasant and uncaring guy... mostly because what he saw when he did care disappointed him in humanity so immensely he now wants to kill them all, and hopes to do it as personally as possible.
• Super Mario Bros.:
  • The Shadow Queen from Paper Mario: The Thousand-Year Door attempts to destroy the Earth and and kill all life on it by covering it in darkness and shadow.
  • The Shroobs in Mario & Luigi: Partners in Time stage an Alien Invasion of the Mushroom Kingdom and seem to take great pleasure in subjugating and slaughtering the native inhabitants. In their Wingdinglish language, there's one particular set of symbols that shows up regularly — and it translates to "DESTROY".
  • In Super Paper Mario, Big Bad Count Bleck doesn't just want to destroy the world, he wants to destroy the multiverse. Dimentio, at least to a very narrowly smaller degree, qualifies as well, as he wanted to usurp Bleck and take the Chaos Heart to destroy most of the universe and then remake it. However, he then decides to go back to destroying existence after he was vanquished, even going as far as to leave a shadow of his power behind with the Chaos Heart so that it can last long enough to destroy everything. Count Bleck himself just wnated to wipe it out and keep it gone along with himself out of sheer grief after his lover was thrown out of reality by his father; part of why Dimentio started lashing out was Bleck found his lover had survived after all and cancelled these plans.
  • The Dark Star/Dark Bowser in the final stages of Mario & Luigi: Bowser's Inside Story. He doesn't have a reason, he just wants to destroy the Mushroom Kingdom and likely universe because he's Made of Evil.
  Dark Bowser: Soon this kingdom will vanish along with all who dwell within. And you, too, will sleep eternally in the dark power's embrace!
  • In Luigi's Mansion: Dark Moon, King Boo becomes one by attempting to destroy the fabric of the universe by summoning a giant paranormal portal that summons a gigantic amount of ghosts that could cause the fabric of reality to be destroyed.
  • In Mario & Luigi: Paper Jam, Bowser becomes one of these. Both versions of him, right before the final battle against them, say that if they win, they will trap the Mario Bros. and Paper Mario into the book containing the latter's universe. Then they declare that they will throw it in the garbage and "light the garbage on fire". This becomes very unsettling when you realize that Paper Bowser wishes to destroy his own universe without a care in the world, and doesn't care about the consequences!
  • In Mario + Rabbids Kingdom Battle, the Megabug attempts to destroy both the Mario and Rabbids universes.
    • In it’s sequel, Mario + Rabbids Sparks of Hope, the Megabug’s reincarnation, Cursa, attempts to destroy the universe by covering it in darkness.
• Tales of Graces sees Lambda attempt to invoke this because Humans Are Bastards. What he doesn't count on, however, is Asbel being smarter than he looks. Asbel deconstructs the trope by pointing out how the destruction of all life accomplishes nothing, doesn't solve any of the issues that people have and doesn't even benefit the one who enacts it in any way (as they will be the only being left alive... and not all the time). This complete obliteration of Lambda's goal is what inspires him to accept Asbel's offer of letting the world live and allowing Asbel to show him that Humans Are Special.
• Dorian General Grants, the Big Bad of Tales of the Abyss, 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.
• Tekken 8: Devil Jin's ending, Jesus Christ... Being an alternate retelling of the Story Mode's Downer Beginning where Alisa, Lars, and Lee are killed by the UN. Devil Jin goes on a rampage around Manhattan and proceeds to shoot down the satellites attacking him, before he proceeds to smoke everyone and everything from space with a powerful Devil Beam, reducing the Earth into a smoking crater, and the scene ends with Devil Jin starts laughing jubilantly at the sight of the Earth's destruction..
• Karras in Thief II: The Metal Age thinks that life is messy and inefficient. To make a world worthy of The Builder, it's all got to go. He intends to accomplish this with a powder that consumes living material in a self-sustaining chain reaction. That doesn't go so well for him.
• Utsuho Reiuji from 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.
• Both the Primagen and Oblivion in the Turok series.
• Undertale:
  • The main one is 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 Golden Ending, 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.
  • In the Genocide Route, the player can become one of these! This game brutally deconstructs the idea of mooks, and makes it clear that EVERY Random Encounter you kill is a person with family and friends, and as such, Level Grinding is the most evil thing possible. If you proceed to kill everything and everyone despite multiple warnings of its horrible consequences, several You Bastard! moments, and the tagline being "THE RPG WHERE NOBODY HAS TO DIE", prepare to have a bad time.
  • While Alternate Character Interpretation abounds with the First Child/Chara and how much of an example of this they really are, the most straightforward interpretation is that they are a very played-straight example: Should you finish a No Mercy/Genocide Route, you come face to face with Chara, who is revived through the player's own Omnicidal Maniac actions, seems to be someone/something Frisk transforms into upon completing the run, and whose appearance spells the end of what's left of the Undertale universe. Regardless if the player agrees to their proposition to destroy the rest of the world or not, Chara does so, and upon restarting the game, there is nothing left but empty blackness and a howling wind. Chara also has the ability to bring back the world as well, but will only do so if you hand over Frisk's SOUL, and the Golden Ending is permanently derailed in a way that heavily suggests that they steal Frisk's body and destroy the world anyway.
  • In the alternate universe spin-off Deltarune, Chapter 2 reveals the currently-unseen Knight might be this. The Dark Fountains it's been creating can summon the Titans and cause The End of the World as We Know It if there are too many of them. That said, it's unknown if the Knight is actually aware of this or not, because at least one of its closest supporters had zero idea this would happen.
• View from Below: The Crimson God's goal is nothing less than the eradication of humanity for crucifying him as Jesus Christ.
• The Burning Legion in the Warcraft games has, as its goal, nothing less than the complete eradication of all life in the universe — and, according to the Back Story, 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. Players naturally get to punch him out.
  • Apparently the Twilight's Hammer cult is composed entirely of such maniacs. The ultimate goal of the cult is to bring about the end of Azeroth by any means necessary.
  • In World of Warcraft's third expansion pack, the Big Bad, Deathwing, is an example of this. When fighting him 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 End Time, He would have then killed himself to extinguish all life in the world. His minion/son, Ultraxion, 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).
  • Not limited to the "Bad guys" either though. The optional boss in Ulduar is Algalon the Observer. He is a constellar, a herald of the Titans. He has decided that the world is infected with void taint and must be "re-originated": a technical term meaning that all fleshy life on the planet has to be eradicated. Your job as the players is to convince Algalon that the void taint does not make you weak by beating the crap out of him.
• Mother from Wild ARMs believes destroying the worlds she visits is her destined role in the cosmos. 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 devour and possess him to make sure he is.
• Xenoblade Chronicles 2:
  • Malos wants to destroy the world. He never gives any explanation or justification; he just hates absolutely everything. Mythra theorizes that he doesn't actually have a reason, but he's just following some base instinct that he doesn't understand. This is because Malos inherited this desire from Amalthus, the man who originally awakened him. Amalthus hates everyone and everything because his mother was killed by soldiers and then he brutally murdered the men who killed her. The rest of Amalthus' life wasn't much better. Malos got the desire to destroy the world, but none of the reason behind it. It should be noted that by the time of the story, Amalthus himself has moved past this motivation (he still hates everything, but is content to manipulate the world politically and only goes ballistic when people try to climb the World Tree and meet the Architect, which he believes they are unworthy of). Rex tries to talk Malos down at the end with this reasoning, but Malos has lost too much to give up, no matter how little sense it makes.
    Rex: Malos. Is this really what you want?
    Malos: Huh?
    Rex: Is this what you want?
    Malos: I... don't understand the question.
  • Malos's Driver, Amalthus, has a bad case of this as well. After personally witnessing 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 acts of kindness to others repaid with violence to others), he climbed the World Tree intent on getting a direct audience and answer from The Architect about why they live in a Crapsack World. What he found instead was Lost Technology in the form of war machines, a lifeless Elysium, and finally the Core Crystals of the Aegises, themselves capable of destroying the world. At that point, he not only decided this meant the world was not just forsaken and 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, but had long ago decided to never meddle with his creations again and let them do what they may). While Amalthus isn't directly destroying the world like Malos, he has intentionally and knowingly set the world on the inevitable path of destruction by disrupting the life cycle of the Titans—essentially, genociding the very continents that people live upon.
• Id from Xenogears wants to kill everyone and everything, for rather vague reasons. Granted, 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 Xenon in the X-Universe started out as terraforming drones. After a badly coded software update, they went haywire and now attempt to terraform all biological life out of existence.
• Zone of the Enders has Nohman, who fancies himself as an agent of the universe's natural will towards its own destruction. Although he does seem to enjoy it just a little too much.
