[[caption-width-right:350:"BLOOD FOR THE BLOOD GOD!\\

->''"I am called a villain, but mine is a doctrine reflected in the unspoken truths behind all other philosophies. Recognize that truth, my child: Strife is the single element most essential to meaning and existence. Without conflict, without struggle, all of creation might as well be so many unmoving, unfeeling stones. Without me to hate, who would have cause to call themselves holy or just?"''
-->-- '''The Book of Charnel''', ''VideoGame/{{Sacrifice}}''

In a polytheistic religion each God and Goddess serves a specific role and fills a certain niche: {{love|Goddess}}, life, {{war|God}}, [[{{Psychopomp}} death]], and everything in between; be it Aardvarks or Zebras. One such incredibly vital purpose, believe it or not, is Evil.

Please allow us to play as (uncomfortably) literal Devil's Advocates. On the one hand, the BalanceBetweenGoodAndEvil must perforce have Evil to balance Good, lest the latter become [[GoodIsBoring an intolerant conformist theocracy]]. Likewise, it also serves as a definition of what ''not'' to do for worshipers of all the Good and Neutral gods. Most importantly for purposes of this Wiki, it also serves as an excellent plot enabler and antagonist for the heroes and forces of good to fight against.

Being the absolute apex of the SlidingScaleOfVillainThreat, TheChosenOne can spend an entire series fighting their way up from the ReligionOfEvil, the [[HighPriest Black Pope]], its DarkMessiah, and then fight the God of Evil itself... or at least enable a good god that was a SealedGoodInACan to do so.

This God/dess Of Evil can take any shape or form... not just as a master [[ManipulativeBastard tempter]] and [[ShapeShifter deceiver]], but because evil includes a [[EvilTastesGood heady]] and [[EvilTropes large portfolio]]. As Characters they can have as varying a range of personalities as any normal villains.

Here are a few popular variants: Standard Gods Of Evil can [[SatanicArchetype take after Satan]], [[TheParagonAlwaysRebels being rebels]] from [[LightIsGood The Light]] or GodOfGood and tempting peasant and king alike. Kind of a non-denominational counterpart of CrystalDragonJesus. However, most aren't futile rebels; they are very real and threats often motivated by goals other than rebellion for its own sake. TheGrimReaper is at times [[EverybodyHatesHades represented as a God of Evil]], wanting nothing but the death of every living thing, and [[EnemiesWithDeath the protagonist in particular.]] War too may be shown this way, desiring to bring about a world where AsskickingEqualsAuthority and the weak are killed just for being weak... which does raise the question of whether or not it's ironic for heroes to vanquish them by fighting. If they have any philosophy, ethos, or commandment, it's usually that MightMakesRight, that ethics and morality are mere shackles for TheFettered masses of {{Muggles}}, and that Evil represents the path to power.

Not surprisingly, they tend to be cruel, dominating and treacherous. If there is more than one God of Evil in a setting, they usually engage in EvilerThanThou, betraying each other before any lasting headway against the forces of good can be made. Their metaphysical home, where worshipers and non-worshiping sinners end up, is usually akin to {{Hell}}. Given the above, why would anyone [[GodsNeedPrayerBadly worship them?]] Well, they usually offer worshipers power in life via a DealWithTheDevil, [[ReadTheFinePrint fine print]] and afterlife be damned (literally). Plus, just because they'll go to hell [[ImmortalityImmorality if/when they die,]] doesn't mean they'll be tortured souls... they might become the ''[[AHellOfATime torturers]].'' Provided they don't [[YouHaveFailedMe fail their dark lord]] first, that is. And of course, most gods of evil are worshipped out of fear of [[TrappedInVillainy what would happen if they ''stopped'' worshipping]]. Is it any surprise their pawns in the DivineChessboard are usually unwitting or unwilling?

Their followers include {{Cult}}s, the ReligionOfEvil and PathOfInspiration. {{Necromancer}}s and Infernalists usually get their powers by worshipping them. Expect them to forge many an ArtifactOfDoom as a source/repository of their power. When they or their agents are actively recruiting, expect them to be TheCorrupter. They're a CardCarryingVillain by definition and sometimes the God of Evil is also [[MadeOfEvil literally Evil.]] Likely candidate for UltimateEvil and AsLongAsThereIsEvil. A [[TheTheocracy theocracy]] to one of these is probably TheEmpire. May be creator of an AlwaysChaoticEvil race. May have a [[DeadlyDecadentCourt court]] of DemonLordsAndArchdevils, or if they exist at all these may be upstarts or otherwise in opposition. Gods of evil may have TheLegionsOfHell at their command.

Often, there is a GodOfGood who stands in opposition to the God of Evil; the two are locked in an [[ForeverWar eternal]] DivineConflict that dictates the BalanceBetweenGoodAndEvil. The GodOfGood has his own agents or agent to fight against the God of Evil.

Contrast EldritchAbomination, which, as horrifying as it may be and act, is completely amoral and not malicious. Compare GodIsEvil, and EverybodyHatesHades. If a God of Evil exists in a setting where the BigBad who actually drives the plot is a mortal, they'll be the BiggerBad. May overlap or also be a MadGod. May be TheAntiGod if it's powerful enough.

'''To avoid FlameBait and {{Edit War}}s, note that this trope isn't about gods who simply ''are'' evil, it's about gods ''of'' evil.''' JerkassGods that are petty, vain, or prone to DisproportionateRetribution do not qualify.



[[folder:Anime & Manga]]
* Jashin of ''Manga/{{Naruto}}'' means [[ExactlyWhatItSaysOnTheTin "Evil God"]]. He/she/it is mostly an excuse to allow his follower Hidan to practice his ReligionOfEvil BloodMagic (read: fight and kill people). The Ten-Tails also counts, despite being the progenitor of all that exists in the world.
* Ruby-Eye Shabranigdo in ''Anime/{{Slayers}}'', along with three other Dark Lords that exist in TheMultiverse it features. Before the world as everyone knows it existed, Shabranigdo started a war against the Lords of Light. The war almost destroyed existence itself, but the Lords of Light prevailed and the world was created.
* Dark Star Dugradigdu in ''Anime/LostUniverse'' is named after one of the above-mentioned Dark Lords, and is sometimes believed to be one and the same as him.
* [[spoiler: The Idea of Evil]] and the God Hand from ''Manga/{{Berserk}}''. The former is interesting in that is was [[spoiler:made [[GodsNeedPrayerBadly from our need]] for there to be a God of Evil.]]
* In ''[[Anime/PuellaMagiMadokaMagicaTheMovieRebellion Puella Magi Madoka Magica The Movie Rebellion]]'' [[spoiler:Homura becomes a goddess of evil and suppresses Madoka's powers as the [[GodOfGood goddess of good]] in order to bring her back to earth and erase her memories. She actually comes off as an AmbiguouslyEvil WellIntentionedExtremist given that she just [[IWantMyBelovedToBeHappy wants Madoka to be happy]]...which means making everyone else happy.]]
* [[spoiler:Zorc/Zork Necrophades]] (spelling varies on translation), the EldritchAbomination from ''Manga/YuGiOh''. He's the god of darkness and ultimately the main villain of the series, [[spoiler:who either controlled or was directly allied with some of the biggest villains earlier.]]
* ''Anime/SailorMoon'' gives us [[spoiler: Chaos]] and it's [[HumanoidAbomination humanoid]] incarnation [[spoiler: Sailor Chaos]].

[[folder:Comic Books]]
* For DCComics:
** {{Darkseid}}, the BigBad of Creator/JackKirby's ''ComicBook/NewGods'', has been called the God of Evil by many people in the DCU. And in ''FinalCrisis'' he comes close to being a full-blown EldritchAbomination -- [[spoiler:''his very existence'' is causing reality to die]]. Just to bring this point home, here's what Boss Dark Side says: "There was a war in Heaven. ''I won''." He is the poster boy for DystopiaJustifiesTheMeans- his goal is to turn the entire universe into an even more hellish version of Apokolips, a world of perpetual enslavement and burning fire pits where the only purpose you are told to have is to endlessly worship Darkseid.
** Ares, God of War, is the ArchEnemy of WonderWoman.
** [[ComicBook/TeenTitans Trigon the Terrible]] isn't just referred to as a god, but the Literal Manifestation of ALL Evil that has ever existed. Think Dormmamu, but in the DC Universe instead of Marvel.
* And for the MarvelUniverse:
** The Elder Gods, powerful magical entities native to Earth, born billions of years ago shortly after the planet was created. While they did not originate as evil, they began [[ImAHumanitarian cannibalizing]] each other once they found out that they could gain more power that way, eventually degenerating into extremely powerful demons. Only Gaea and Oshtur did not join their brethren; the latter fled to another dimension and eventually became one of the Vishanti, while the former birthed the entity Atum which proceeded to [[HoistByHisOwnPetard hunt down and eat the Elder Gods themselves]]. A handful escaped into other dimensions and Gaea and Atum set up numerous magical barriers to hamper their returning, while Atum degenerated himself into the evil creature the [[MadeOfEvil Demogorge]] due to the demons he consumed; he expelled this from himself and it became TheLegionsOfHell- demons such as Thog and Mephisto-, while he retired to live in the sun. The Elder Gods include:
*** Set, a multi-headed serpent who was the first to cannibalise, and the demon partly responsible for the death of the dinosaurs; he managed to bypass the barriers and started feasting on the life energies of the dinos, but after learning Gaea planned on making them extinct and starting over with mammals, used mind control to send them to kill all mammilian creatures. Gaea responded by waking up Atum and the battle between the two, apart from costing Set his original head (two more kept replacing them when Atum cut them off, until he had seven), ended up causing the extinction event itself and left Set so weakened he had to flee again. He later returned as a major recurring villain during Marvels take on ConanTheBarbarian.
*** Chthon, the writer of the Darkhold, an evil magical tome responsible for, amongst other things, the creation of [[OurVampiresAreDifferent vampires]]; the god of Chaos, and more specifically [[BlackMagic chaos magic]]. He is the source of the power of the ScarletWitch, with the long term plan of using her as a host, and is currently [[SealedEvilInACan sealed away in Mount Wundagore]] (or at least, part of him is), which became the magical (and irradiated) source of clay for ComicBook/FantasticFour villain the Puppet Master. He is the EvilSorceror of the group.
** Aside from the Elders, the regular gods are divided into pantheons, each of which has their own bad guys:
*** SelfDemonstrating/{{Loki}}, foster brother and ArchEnemy of TheMightyThor, is the God of Mischief and Evil in Marvel's Norse pantheon, a powerful magician and ManipulativeBastard extraordinaire who seeks to conquer Asgard and kill his heroic sibling. He is technically not a god, but a very small, god-sized Frost Giant, adopted by Odin as a babe as penance after Odin slew his father in battle. Loki bares no real grudge for ''that'' (in the comics, anyway), but instead grew resentful because he thought Thor was treated as the favourite, especially by other Asgardians. As boys, he often tricked Thor into getting into dangerous situations hoping he would die in the process, and as full grown gods got him banished from Asgard on several occasions. Accidentally caused the formation of Comicbook/TheAvengers when he pitted Thor against the Comicbook/IncredibleHulk, and remains one of their most persistent and powerful adversaries, often by giving common thugs superpowers and sending them into battle against them, or using his magic to cause all sorts of trouble. He is the father of various evil creatures as well as Hela, Goddess of Death, who borders on an EverybodyHatesHades evil god herself.
*** Amatsu-Mikaboshi, for the Shinto pantheon, a demonic creature and a malevolent Death God (not their ''only'' death god, just their bad one) that serves as the God of Evil for those gods, and their most primal enemy. He/ she/ it is the AnthropomorphicPersonification of the primordial darkness that once ruled the Earth after the defeat of the Elder Gods; prior to ''that'', it once ruled the Marvel Universe and prior to ''that'', it ruled the universe preceding ''that'' universe, and originally was the nothingness before existence. Over time it had to constantly descend as it dealt with the various new creatures and gods that peppered the planet It regained some of its old stature [[spoiler: by slaughtering, eating and enslaving hundreds of gods and demons (notably Zeus and Nightmare) to become the Chaos King, where it (re)joined the cosmic pantheon alongside Eternity and Death, seeking to destroy the multiverse and return it all to primordial darkness]]. At full power it just falls short of being some kind of Anti-God, though it might be more accurate to say it is anti-Creation, preferring to exist in and rule over a chaotic nothingness.
*** Set, ''not'' the Elder God but the God of Evil for the Heliopolitan (ie. Egyptian) pantheon, based on the mythological Set but, in-universe, taking the name of the Elder God for its badass connotations. Like Set and Loki, he uses magic and soul-stealing to enhance his powers, to the point he now rivals Odin, arguably the most powerful god in any pantheon.
*** EverybodyHatesHades and, as Pluto, this Death God of the Greek pantheon serves as their resident bad guy, and enemy of Marvels' Hercules. In DC he is portrayed more faithfully as a more neutral figure. Aside from him there is Ares, God of War, though in recent years Ares has become an AscendedExtra and morphed into an AntiHero, albeit a very dark and violent one.
** {{Eldritch Abomination}}s like Shuma-Gorath and Dormammu are worshiped as gods in the dimensions they rule over, and numerous others, and wield nigh-omnipotent power arguably above every other god previously mentioned, at least at full strength and in their own worlds. For both Shuma-Gorrath and Dormammu, [[GodsNeedPrayerBadly worship serves as a source of power]], though for Shuma-Gorath, both his power and physical size is based off how much fear he can induce in the realm (in his native Chaos Dimension, he is larger than a galaxy), and commanding regular human sacrifices worked well enough. Both seek to conquer the Earth- Shuma-Gorath has actually already done this, twice (first during the age that ConanTheBarbarian takes place in), in ancient times- and can be guaranteed to torture and kill everything on the planet/ universe if they ever succeed. Hell Lords like Mephisto wield godlike power within their dimensions, but are not treated as gods per say, or seemingly worshiped in any way except by the odd gullible mortal. In fact, the description of the Hell Lords listed on SatanicArchetype explains why NONE of them ever try to become the one true god of evil.
** Some other Marvel supervillains are sometimes worshiped as gods themselves, most notably [[ComicBook/{{X-Men}} Apocalypse]] who was, as it happens, also mistaken for Set and various other gods throughout his immortal lifespan, and would use this influence to force civilizations to fight to the death until only the strongest survived. In the ''Legacy'' novel series Magneto was worshiped as God on Genosha, while DoctorDoom has successfully stolen godlike power numerous times from cosmic beings, though on such occasions he prefers to be actively worshiped as a King or Emperor rather than a deity. Selene, another X-Men villain, is a 17,000 year old vampiric mutant sorceress named after and sometimes worshiped as a goddess, the attainment of which is her ultimate goal. The GreenGoblin once ''thought'' he was one of these, but he was actually just driven mad(der) by an ArtifactOfDoom.
** The BigBad of ''ComicBook/FearItself'' the Serpent is the Asgardian god of fear [[spoiler:and Odin's brother Cul Borson.]]
* Anathos from [[ComicBook/LesLegendaires Les Légendaires]]; he was part of the Gods who created Alysia, but turned against them because he wanted to become a "Mastergod", destroyed the original Alysia, was [[SealedEvilInACan sealed away]] by them after his defeat and came back in order to attempt TheEndOfTheWorldAsWeKnowIt. He even stated to have created this universe's version of Hell.
* In the ''{{Nodwick}}'' print comic, Baphuma'al is one of several evil gods (being a D&D-style setting, he seems to be a little-known or mostly forgotten deity of magic and undeath). He serves as BigBad of the comics because he explicitly broke the 'rules' all the gods play by and is actively trying to ascend to the level of ThePowersThatBe and TakeOverTheWorld. The other gods weren't overly concerned [[BecauseDestinySaysSo they know he's doomed to fail anyway]] until our noble heroes [[ScrewDestiny inadvertently messed it up]].

[[folder:Fan Works]]
* FanFic/DungeonKeeperAmi features and entire pantheon- and Ami is out to make enemies of them All! First, there's Azarratha, The Mighty Tyrant (God of Martial Force), [[{{Psychopomp}} Crowned Death]] (God of Undeath and Necromancy), [[GlaDos The Unraveller of Mysteries]] [[MadScientist (God of Amoral Curiousity)]]. In addition, the Vermin Lord and Flame Emperor have been mentioned...
* The ''FanFic/PonyPOVSeries'' has Discord's parents Havoc and Entropy, the {{Anthropomorphic Personification}}s of mass hysteria and heat death, respectfully, who have the attitudes to match.
** A straighter example is [[{{Satan}} Morning Star]], a [[FallenAngel Fallen Alicorn]] who was originally supposed to be the embodiment of Perfection and Beauty, but after falling became Temptation and Evil. Where Havoc and Entropy are {{Eldritch Abomination}}s that run on BlueAndOrangeMorality, Morning Star is described as being as evil as Discord is.
** There's also Father Deer, the [[DirtyCommunists Hooviets']] deity. He's basically said to be the embodiment of their 'Greater Good' philosophy...which is just a fancy way to say 'destroy freedom, stomp all non-deer races under an iron hoof, and TakeOverTheWorld'. However, there's question in universe as to whether or not he even ''exists'' (he doesn't).
** The straightest example besides Morning Star is Nyarlathotrot, the personification of the collective darkness of the [[HumansAreCthulhu Shadows Who Make]]. As such, he rules over, and is implied to ''create'', the [[DarkFic Grim Dark Worlds]] based off such works as ''Fanfic/{{Cupcakes}}'' and ''Fanfic/CheerileesGarden''. Thankfully [[spoiler:Amicitia]] purified many of his worlds and tricked him into losing the ability to ''corrupt'' good ones, and he has a counterpart in Fillimon, the personification of the Shadows' collective light. Both their names are references to Nyarlathotep and Philemon mentioned under ''VideoGame/{{Persona 2}}'' below.
* The ''FanFic/PoniesOfOlympus'' series has Erebos, the god of darkness, who seems to be the BigBad. He was the one who [[TheCorrupter corrupted]] Luna into Nightmare Moon in an attempt to bring about eternal night. On top of that, he's also [[TheManBehindTheMan Chrysalis' master]].
* ''FanFic/{{Eugenesis}}'' mentions that the Quintessons have five gods, all of them as twisted as the Quints. Case in point, one of them is [[EldritchAbomination Unicron himself]].

* La Magra, the vampire Blood God from the ''Film/{{Blade}}'' movies. The evil scheme in the first film is to complete a ritual to summon him into a vampire avatar so he can walk the earth. If he fights humanity, he will turn everyone into vampires by his mere presence. [[spoiler:Deacon Frost summons La Magra into himself and becomes much more powerful, being made entirely of blood and showing insane regenerative powers. Blade kills Frost by loading him with anti-coagulents, but it's unknown if this killed La Magra too.]]
* ''Film/TheFactsInTheCaseOfMisterHollow'' follows an OccultDetective's investigation of a MysteryCult in northern Ontario that engages in HumanSacrifice and worships the Keres, understood to be evil Greco-Roman goddesses. Though not detailed in the film itself, in Myth/ClassicalMythology they are the ''daimones'' (AnthropomorphicPersonifications) of violent, painful ''death,'' and serve as particularly nasty {{Psychopomp}}s who thirst for human blood.

* Naar, the King of the Darkness from the ''Literature/LoneWolf'' series. He spends most of the series as the BiggerBad, and only takes on a more direct role as BigBad after Lone Wolf defeats his champions the [[EvilOverlord Darklords of Helgedad]].

* Set is the most evil of gods in the ''ConanTheBarbarian'' world.
* Morgoth in ''Literature/TheSilmarillion''. Then in ''Literature/TheLordOfTheRings'', Sauron ''tries'' to ascend to this level, but is more of a ''demi''god of evil.
* The Dark One from ''Literature/TheWheelOfTime'' is one of the quintessential examples of this trope.
* [[Literature/TheChroniclesOfThomasCovenant Lord Foul the Despiser]]. He was imprisoned with Time by his opposite, the Creator, for planting various sources of evil magic into the universe shortly following the creation, and he's been trying to get out ever since- and because he's [[TheChessmaster super-intelligent]] and [[ForTheEvulz unrepentantly horrible]], this generally means misery for everyone else unlucky enough to be stuck in the Land with him.
* From Literautre/TheCosmere by Creator/BrandonSanderson:
** [[OmnicidalManiac Ruin]] from ''{{Mistborn}}'' is something of a subversion- he's definitely a god and as far as humans are concerned he's pretty clearly evil, but he doesn't think of himself as such and isn't interested in either ruling people or corrupting them. He does use mortal pawns, but some of those include ''the heroes'' doing ''heroic things'' that happen to speed along the destruction of the world. He does have some unequivocally evil tendencies (namely a fondness for EvilGloating), but these seem to have been picked up from mortals rather than the reverse.
** ''Literature/TheStormlightArchive'' introduces Odium who fits more directly as a God of Evil being the AnthropomorphicPersonification of hatred. Though he's not shown up in person yet, his reputation precedes him and [[TheDreaded it's not pretty]].
* There's a third of the ''{{Dragonlance}}'' pantheon called the Gods of Darkness, and they're, well, ExactlyWhatItSaysOnTheTin. In something of a subversion, they're considered nasty but necessary parts of the cosmos, though every so often one of them (usually [[EvilMatriarch Takhisis]] or her consort [[BloodKnight Sargonnas]]) gets a bit too ambitious and needs to be put back in their place.
* ''[[Literature/KushielsLegacy Kushiel's Avatar]]'' by Jacqueline Carey involves Angra Mainyu, taken from real life Zoroastrianism. (See the Real Life section below for more details.)
* In ''Literature/{{Animorphs}}'', Crayak is effectively this - at the very least, he plays TheSocialDarwinist on a cosmic scale, using shock troops like the Howlers to weed out weaker species.
* Creator/DavidEddings likes this one:
** In ''Literature/TheBelgariad'', BigBad Torak is one of these and losely follows the {{Satan}} model, as does the mentioned but never directly confronted [[NamesToRunAwayFromReallyFast King of Hell]].
** In ''Literature/TheElenium'', Azash is an elder evil that verges on EldritchAbomination if he didn't manipulate human desires so often (though it's clear his understanding of humanity is imperfect, and largely based on the cultural group most of his worshipers come from), while Cyrgon is a straight example and Klael is ''the god'' of Gods of Evil.
** ''Literature/TheRedemptionOfAlthalus'' has Daeva, a god of destruction who morphed into this when he promoted himself from "takes out the cosmic trash" to OmnicidalManiac.
* The Crimson King from Creator/StephenKing's ''Franchise/TheDarkTower'' series definitely qualifies. Before he got nerfed he was depicted as an invincible anti-God that had always existed, but was trapped on a balcony near the top of the Dark Tower. Even trapped his avatar "The Court of the Crimson King" was so powerful that almost no force in King's multiverse could stand against it. Supposedly if his physical body was free he would become utterly infallible, and so he planned to bring the Tower (and by proxy all of existence) crashing down. Later King retconned him into a senile half-god that was not nearly so imposing.
* The ''IncarnationsOfImmortality'' series has this as one of its offices. However, the particular office holder in the series averts this; he's less interested in being a relentless evil and more interested in simply being a fair evil - that is, separating good and evil people through temptation so that they can go to Heaven or Hell rather than stuck in Purgatory.
* In L. Jagi Lamplighter's ''[[ProsperosDaughter Prospero Lost]]'', Theo recounts how the ''Orbis Suleimani'' eradicated knowledge of the supernatural. This was to prevent people from trying to solve problems by appealing to supernatural beings, many of which demanded worship and some of which were evil. Success resulted in the Industrial Revolution.
* Tash is described this way in ''TheLastBattle'', the final book of ''TheChroniclesOfNarnia'', with CrystalDragonJesus Aslan outright stating that Tash is his antithesis. Interestingly, while Tash is very much a CardCarryingVillain, his own religion is ''not'' a ReligionOfEvil, given that it apparently includes a number of sincere followers who believe Tash to be a just and righteous god. It gets better - Tash is so evil that you cannot commit a good act in his name - they automatically are assumed as your service to Aslan. The opposite is also true - if you do something terrible in the name of Aslan, you're really serving Tash.
-->'''Aslan:''' No service which is vile can be done to me, and none which is not vile can be done to him.
* Gyphon from ''{{Mithgar}}'' is both the overarching BigBad of the series and its primary God of Evil. Specifically, he represents tyranny, since he holds to the belief that the strong should use their powers to control the weak and in fact opposed giving mortals (and non-divine immortals) free will in the first place. Other, lesser Gods of Evil who follow him are namedropped occasionally, but none of them ever do anything directly and very little is ever revealed about them.
* The "nuclear chaos" and "daemon sultan" at the center of the universe, the [[EldritchAbomination Outer God]] Azathoth of [[HPLovecraft H. P. Lovecraft's]] CthulhuMythos is often at times interpreted as this. Judging by what would happen if Azathoth's literary inspiration, [[LordDunsany Mana-Yood-Sushai]] [[SealedEvilinaCan awakens]], it would likely seem that Azathoth has the power to end everything in the universe, including all the other eldritch horrors - but for now [[FortheEvulz just chooses not to]]. Throughout Lovecraft 'cannon' Azathoth is frequently referred to as the "blind idiot god", not because it is in any way stupid, but because you would have to be a blind idiot to worship it.
* ''Literature/MalazanBookOfTheFallen'':
** The Crippled God Deconstructs this trope. He essentially fills this niche, but he's more like a god of suffering than evil- and while he certainly inflicts more than his fair share of suffering on the world, he also [[WoobieDestroyerOfWorlds continually suffers himself]]. [[spoiler: In the end, after a bunch of {{AbusivePrecursor|s}} {{Knight Templar}}s hijack his power, he ends up becoming a more sympathetic deity who empathizes with those who suffer]].
** Bellurdan Skullcrusher, the Dying God, is the trope more or less played straight, [[TheCorruption corrupting]] people with his toxic blood into becoming his [[ReligionOfEvil followers.]]
* The HighFantasy metaseries consisting of ''The Scared Hunt'', ''Literature/TheSunSword'' and ''The House War'' has Allasakar, more commonly known as the Lord of Hell or the Lord of Night (or, to his demons, simply "the Lord"). The most belligerent (and powerful) member of the pantheon, back when the gods still lived in the mortal world he attempted to conquer it; when the other gods left, they only convinced Allasakar to leave as well by giving him Hell has a consolation prize[[note]]And because he was wounded in battle with a mortal champion, something he'd previously considered impossible[[/note]]. Owing to how the cosmology is set up, all souls are reincarnated through many lives until they either attain an enlightened state or become irreversibly corrupt; Allasakar gets the latter. His goal now? Assume dominion of the mortal world to make it impossible for souls to develop as they need to, ensuring that ''all souls'' will eventually end up in his domain.
* In ''Literature/DarkHeart'', Vraxor, one of the three gods of Caliel, is a demon who rose to divinity. His religion is run by a sinister, all-powerful priesthood and is centered around human sacrifice.

[[folder:Live-Action TV]]
* Dahak from ''Series/HerculesTheLegendaryJourneys'' and ''Series/XenaWarriorPrincess'' is described as being the source of all hate, and the worst of the JerkassGods won't hesitate to stop it from achieving the power it desires.
* The First Evil from ''Series/BuffyTheVampireSlayer'' exists AsLongAsThereIsEvil, and is ultimately responsible for every evil being and act in the series.
* ''Series/{{Charmed}}'' had The Source of All Evil (usually just referred to as The Source), who was the ruler of the underworld and the BiggerBad for the first half of the series' run. It was later revealed that "The Source" was actually a primordial force that lived inside whatever demon was currently leader of the underworld at the time.
* In "[[Series/DoctorWho Doctor Who]]" the Black Guardian could be seen in this role, being the AnthropomorphicPersonification of Chaos.
** There is also Fenric, who according to the Doctor is evil from the dawn of time. The expanded universe retconned Fenrir as being another name for the [[HPLovecraft Lovecraftian]] diety Hastur.

[[folder:Mythology & Religion]]
* Some more dualistic forms of Zoroastrianism claim Angra Mainyu (better known by the Persian name ''Ahriman'') is the EvilCounterpart to [[GodOfGood Ahura Mazda]]. In other words, he is essentially the anti-God, or the god of evil. Angra Mainyu isn't so much a name as a title alluding to his nature. Angra can be translated as "destructive" or "malign", while Mainyu can mean "spirit" but also "mind", "concept" or "thought". [[FridgeBrilliance Which means]], Angra Mainyu is ''the'' [[Manga/{{Berserk}} Idea of Evil]]!
* Myth/EgyptianMythology:
** Apep (or Apophis) is the monstrous serpent that tried to eat Ra every night and wasn't so much worshipped as worshipped ''against'', straddling the line between God of Evil and EldritchAbomination.
** Set is portrayed as this to a degree in later versions of the mythology, though contrary to popular opinion he ''wasn't'' a snake god, and was actually a ''good guy'' in earlier myths; Set lost ground as the Horus cult gained it in later centuries, and became more identified with foreigners and the desert, even becoming identified sometimes with the chaos-serpent he had used to fight. By the time Petrarch recorded the most familiar-to-moderns versions of the Egyptian gods, he was bidding fair for this role.
* ''Literature/TheBible'':
** Meta-subversion. {{Satan}} is [[TheAntiGod often portrayed this way in Western media]], as a direct EvilCounterpart of {{God}}. This is the result of WordOfDante however and in contrast to most Christian doctrine, where Satan [[TheDevilIsALoser is recognized as being a far lesser power than God and has no chance of succeeding in his cosmic takeover bid]]. He's never described as being a ''representation'' of evil, merely [[FallenAngel an evil angel]]. However, while angels are nothing compared to YHWH that's because He's an [[TheOmnipotent omnipotent]] CosmicEntity beyond all space-time, and angels still have god-like power (in the lesser sense). A comparison would be that Zoroastrianism portrays Ahriman as an EvilOverlord of a hostile empire, while Christianity portrays Satan as a terrorist.
* The Demiurge of Gnosticism is a giant [[EldritchAbomination snake-lion-sun thing]] who created the physical world and all life in it. He is usually portrayed as prideful, destructive, myopic and dangerous. Interestingly, he is often depicted as thinking himself to be not only a good god but the only god period.
* In Shinto Ama-no-Kagaseo is the AnthropomorphicPersonification of Amatsu-Mikaboshi, which is essentially TheDarkSide. So it is the personification of Evil, or at least discord, destruction and chaos, and destructive impulses.
* Medieval Maori religion gives us Whiro, who manages to some way or another cause practically every problem we have while locked in the underworld. He will eventually escape and destroy everything besides himself and the ashes.
* A religion that has conquered another religion often turns the old gods into demons. This is the origin of the word "demonize". [[AndKnowingIsHalfTheBattle And now you know]].
* Mayan Mythology has Ah Puch. Even though Mayans in general revered their sacrifice demanding gods, BlueAndOrangeMorality and all, Ah Puch was feared because he's one of the few death gods in any ancient religion that actively seeks to increase the population of his dominion, actively prowling the jungles at night seeking innocents to drag to his plane of hell for eternal torture and sending zombie minions after those who run (thankfully, those killed by zombies can't be claimed by him). He's also strongly associated with [[OminousOwl owls]].

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'' usually has at least one (but usually three) in each setting.
** ''{{Dragonlance}}'', being almost entirely about the BalanceBetweenGoodAndEvil, divides all its gods into gods of good, gods of evil, and gods of neutrality. Obviously, each of them does have the own unique spheres of influence above and beyond their alignment.
** In the ''TabletopGame/ForgottenRealms'' there are multiple evil gods, and like in ''Dragonlance'' they are more about malign things than actually being the incarnation of evil. The closest the setting has to a God of Evil would be Shar, the evil goddess of darkness and loss. She is the dark twin of Selune, good goddess of light and hope: According to ''Forgotten Realms'' lore, the twin goddesses were the first beings to come into existence in the ''Realms'' and created everything within it: They represent the primal forces of light and darkness in its purest form. [[GoodIsImpotent Shar is currently more powerful than her twin because Selune's role has been eclipsed by various other good deities]], while Shar's has remained inviolate.
*** Another applicant for the role as official god of evil was Jergal, the Lord of the End of Everything, who was responsible for all strife that plagued mortals while alive, for killing them, and for the afterlife (or, specifically, the afterlife of everyone who weren't spoken for by another god).
** And in the TabletopGame/{{Eberron}} setting, you've got the Dark Six, a whole ''pantheon'' of these (though they ''can'' have positive effects, they ''do'' have plenty of non-evil worshippers in certain parts of the world, and it's likely they were originally the gods of the [[VestigialEmpire goblin empire]] before humans moved in). There are also the Rakshasa Rajahs, ancient demonic beings who once ruled the world, each corresponding to a different kind of evil. The other main dark powers in the setting (the Dreaming Dark and the Daelkyr) are, however, closer to {{Eldritch Abomination}}s.
** Izrador of the ''Midnight'' setting is fairly standard as dark gods go. The other gods tried to banish him from heaven, but did not expect the unforeseen side effect that it would not only send him to the world of mortals, but also severed all connection between heaven and earth. Think of [[Literature/TheLordOfTheRings Sauron]] if he got his ring back, only worse.
** ''TabletopGame/{{Pathfinder}}'' features six in the basic manual: [[{{Satan}} Asmodeus]], former [[DemonLordsAndArchDevils Archdevil]] and LawfulEvil god of tyranny, contracts, slavery and {{Pride}}; Lamashtu, former [[DemonLordsAndArchDevils Demon Lord]] and the ChaoticEvil goddess of [[AxCrazy madness]], monsters, and nightmares; Norgorber, NeutralEvil god of poison, secrets, greed, and murder; Urgathoa, NeutralEvil goddess of [[{{Plaguemaster}} disease]], undeath, and [[VillainousGlutton gluttony]]; Zon-Kuthon, LawfulEvil god of pain, [[GreenEyedMonster envy]], darkness, and loss; and [[OmnicidalManiac Rovagug]], ChaoticEvil EldritchAbomination of wrath, disasters, destruction, and {{Nietzsche Wannabe}}s. There's also the [[TheFourHorsemenOfTheApocalypse Four Horsemen]] and the Oinidaemon who rule the NeutralEvil, nihilistic daemons and may well be powerful enough to count.
** As of 4th Edition, Tharizdun the Chained God may be the worst of the lot. He's an OmnicidalManiac who is so awful that all of the other gods, good ''and'' evil, [[EnemyMine put aside their differences]] to [[SealedEvilInACan seal him in another dead universe]] after he used a shard of evil to ''create the Abyss''. If he ever broke free, the current universe would soon be as dead as his prison. He was just as bad in ''TabletopGame/{{Greyhawk}}'' as the god of Eternal Darkness, Decay, Entropy, Malign Knowledge, Insanity, and Cold that is worshipped by ''[[EldritchAbomination Eldritch Abominations]]''. He is the literal UltimateEvil of ''TabletopGame/DungeonsAndDragons''.
* The Chaos Gods of ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'' straddle the line between this trope and TheHeartless. They are closer to gods of, well, Chaos rather than Evil, being conglomerations of every mortal emotion; however, the relentless CrapsackWorld means they aren't fed with many good emotions, and those emotions are taken to such extremes anyway that they and their followers inevitably embrace madness, destruction and mayhem.
** [[PhysicalGod The C'tan]] in ''[=40K=]'' have no ambition other than sealing off the warp (which would be bad news for [[OurSoulsAreDifferent anything with a soul]]), killing most forms of life in the universe and feasting on the survivors. Or at least they did, before [[TurnedAgainstTheirMasters the Necrons rebelled]] and [[DidYouJustPunchOutCthulhu shattered them into pieces]].
** There are, however, some fairly unambiguously evil gods in ''TabletopGame/{{Warhammer}}'', although there is generally some argument (in-universe and out) as to whether they are gods in their own right, or aspects of another (and occasionally, as to which other god they are an aspect of). Khaine (God of Murder, Assassins and Poisoners) is a case in point, with some claiming he is an aspect of Khorne as worshipped by the elves[[note]]even to the point of claiming he's an elven blend of Khorne and Slaanesh, and the reason for the emnity of those two deities[[/note]], while some say he's an aspect of Morr (God of Death, Dreams and Omens), and those who say Khaine is a god in his own right are split as to whether he's Morr's younger brother, or one of the children of Asuryan and Eldanesh[[note]]Morr being a human god, while the others are part of the elven pantheon[[/note]]. Stromfels (God of Storms, Pirates, [[EverythingsEvenWorseWithSharks Sharks]] and Wreckers) is in a similar, though less extreme position[[note]]being either an aspect of, or rebellious younger brother to Manann, God of the Sea[[/note]]. The Horned Rat, though, is pretty much a pretty straightforward evil god, complete with his own species of evil anthropomorphic rats to worship him.
** Khaine in ''[=40K=]''. He ''was'' the elven pantheon's God of Evil, but when Slaanesh killed the rest of the gods, only Khaine was able to stand up to him. While he lost the battle with Slaanesh and could not prevent the Chaos god's ascension, he remains alive and the Eldar still pray to him on the basis that he's a monster and a villain, but he's still ''their'' monster and villain. Ultimately, while Khaine is war-like, arrogant and relishes in killing, he remains an Eldar god and doesn't want to see the Eldar die out.
** The two Ork Gods, Gork and Mork, from 40K may be this, or may not. They are the Gods of being "brutally kunnin'" and "kunnin'ly brutal," one hits you in the back while the other hits you when you're looking at them (though no Ork really is sure which is which) and they do like to murder, kill, and fight just as any Ork. They are rarely not actively attacking and fighting anyone besides each other.
* ''TabletopGame/{{Exalted}}'' has the Forbidden Gods, deities whose areas of influence are so thoroughly depraved by any moral standard that they've been cut off from the support of the CelestialBureaucracy and [[ExactlyWhatItSaysOnTheTin are forbidden to be worshipped]].
** If the definition of "god" is expanded a bit beyond the setting's use of the term, the Yozis, the Neverborn, and some behemoths all qualify.
** The Ebon Dragon invented the concept of betrayal, and had a significant hand in creating both fate and free will because the potential suffering caused by the contradiction between the two amuses him; this was ''before'' he became a Yozi. However, the Ebon Dragon is more accurately the God of {{Shadow Archetype}}s, the Primal Nemesis. He defines himself as the Nemesis of Light, so he's Darkness. He defines himself as the Nemesis of Trust, so he's Betrayal. He defined himself as the Nemesis of the Four Virtures of Compassion, Conviction, Temperance, and Valor, so he's Cruel, Pragmatic, Unfettered, and Spineless. In fact, he's stated to not truly ''[[EmptyShell exist]]'' in metaphysical terms-without other beings to state what his evil is, he's nothing at all.
* ''TabletopGame/MagicTheGathering'' has the God of Phyrexia, Yawgmoth, known in several cultures of Dominaria as [[IHaveManyNames the Dark Lord, the Hidden One, and the Lord of Wastes]]. It took a massive effort and the lives of countless people, including several [[PhysicalGod Planeswalkers]], to stop him when he attempted to take over Dominaria and spread dominion over TheMultiverse. While he is believed to be dead, nothing is ever certain with Yawgmoth, and rumors linger that he is still alive, biding his time as he recovers his strength.
** The [[EldritchAbomination Eldrazi]] and [[AGodAmI Nicol Bolas]]. The former were once worshiped as the gods of Zendikar.
** While the ''Theros'' block (based on Myth/ClassicalMythology) averts this with [[EverybodyHatesHades Erebos]], it still has two downrightly evil gods: Phenax, the deity of deceit and lies, and Mogis, the god of bloodlust, savagery and canibalism.
* Two flavours in ''TheDarkEye'': Demons want to destroy creation, the strongest are dark shadows of the major gods. The Nameless God is a renegade god who wants to rule creation and doesn't shirk from anything imaginable (and unimaginable) to achieve that goal.
* TabletopGame/TheWorldOfDarkness has a field day with this trope.
** The Wyrm from ''TabletopGame/WerewolfTheApocalypse'' was essentially the cosmic embodiment of suffering, hatred, and corruption, keen to blight all of existence into a wasted hell hole. Ironically enough, originally he'd been the blessed end that comes to all things, but then [[GoMadFromTheRevelation something very bad happened]].
** The Maeljin from ''TabletopGame/WerewolfTheForsaken'' are the most literal examples, being the spirits of such family friendly concepts as lust and war.
** The Exarchs from ''TabletopGame/MageTheAwakening'' might be this, [[JerkassGods but they might just be assholes.]]

[[folder:Video Games]]
* The God of Death Oswald Leingold from ''[[VideoGame/FantasiaOtomeGameSeries Fantasia - Realm of Thanos]]'', who much prefers to be called the Demon Lord.
* Charnel from ''VideoGame/{{Sacrifice}}'' is a CardCarryingVillain God of Evil who is GenreSavvy about how important his place is in the pantheon. Amusingly, Charnel is publicly the most fervent opponent of the game's FinalBoss, OmnicidalManiac Marduk, as he doesn't like competitors. [[spoiler:It remains ambiguous just how much he knows about who's ''really'' responsible for summoning Marduk and whether his lines of reasoning for siccing you on the other gods are genuine or simply him using you to settle his old grudges.]]
* ''Franchise/SilentHill'' is [[MindScrew unhelpful]] as to whether the power of the eponymous town and the deity its cult attempts to summon is a God of Evil or an EldritchAbomination. It could even very well be entirely neutral, with characters projecting their own evil onto it.
* In ''VideoGame/FireEmblemTellius'', the Goddess of Evil is also a SealedEvilInACan which will awaken when enough violence and fighting takes place. Until it turns out that [[spoiler:she's really just the Goddess of Chaos, counterpart of the "good" Goddess of Order, and mankind cannot exist properly without both of them in balance.]]
* Technically, [[spoiler: Yami]] from ''VideoGame/{{Okami}}'' is the God of Darkness (and Machines), but he could easily be described as this as well. [[spoiler: He rules over all the previous villains of the game and [[ThePowerOfLove is only defeated due to all the people of the world praying for the protagonist to win]].]]
** [[spoiler: Akuro]] of ''Okamiden'' is either his successor or the true God of Evil for the past game.
* Kri from ''RiseOfTheKasai''. Neither it nor its followers make any attempt to hide or justify it.
* The Old Gods of ''VideoGame/WorldOfWarcraft''. Yogg-Saron is all over this one: "BOW DOWN BEFORE THE GOD OF DEATH!!!"
* Shinnok of ''Franchise/MortalKombat'' is a definite God of Evil.
* Falerin of ''VideoGame/AdventureQuest'' is an interesting subversion; he is the God of Evil, but he is not malevolent and bloodthirsty. He's quite gentlemanly and passive; in fact, he helps the protagonists indirectly against the actual BigBad.
* Fain of ''VideoGame/{{Lusternia}}''. He's not an AnthropomorphicPersonification, and eviller "Gods" exist, but given the way he [[DealWithTheDevil tempts]] and [[TheChessmaster manipulates]] mortals ''and'' other Gods, he's the closest (sentient) thing to it in the game.
* The final bosses of ''VideoGame/{{Dragon Quest}}s [[VideoGame/DragonQuestIII 3]]'', ''[[VideoGame/DragonQuestV 5]]'', ''[[VideoGame/DragonQuestVI 6]]'', ''[[VideoGame/DragonQuestVII 7]]'', and ''[[VideoGame/DragonQuestVIII 8]]''.
* ''VideoGame/{{Persona}}'''s Nyarlathotep, an EldritchAbomination AnthropomorphicPersonification of ''the entirety of Humanity's collective evil''. He was cast away at the end of ''2''. ''VideoGame/Persona4Arena'' introduces the "Malevolent Entity" who is one of those, and is confirmed in [[VideoGame/Persona4ArenaUltimax the sequel to be]] [[spoiler:''not'' Nyarlathotep, but Hi no Kagutsuchi, the personification of humans' selfish desire for solitude and isolationism, who wants to bring this concept to [[OmnicidalManiac its logical conclusion]].]].
* The Daedric Princes of ''Franchise/TheElderScrolls'' are generally regarded as such by human society. Most of them are just very morally flexible with how they and their followers accomplish their goals--no Prince's domain is straightforward "evil". However, Mehrunes Dagon is the Prince of [[BloodKnight chaos and destruction]], Molag Bal is the Prince of dominion and rape, and Vaermina is the Prince of fear and nightmares, so they more or less fit the trope to a T.
** And within that set, Molag Bal is the closest there is to an actual God of Evil. While Mehrunes Dagon and Vaermina simply have domains with negative connotations (and Mehrunes has some with fairly neutral connotations, it's just that he favours the more negative ones), Molag Bal is also the god of corruption - he gets his power by making mortals do evil deeds. Essentially, he's the ''Elder Scrolls'' equivalent of {{Satan}}, particularly the older depictions of Satan when he was more of a corrupter of mankind than a general embodiment of evil.
** Also Sithis is said to be a representation of one of the primordial states of chaos. He is the patron god of the Dark Brotherhood assassins. He is technically neither Daedra or Aedra. [[http://www.uesp.net/wiki/Lore:Sithis The Unofficial Elder Scrolls Wiki]] has a full writeup, based on all the references to "him" in the games.
* {{Medusa}} in ''VideoGame/KidIcarus'' is the goddess of darkness in a world were DarkIsEvil. Her sister is the goddess of light.
* ''VideoGame/ReturnToKrondor'' has Narlor, the Dark God. A god that had to be [[SealedEvilInACan sealed]] away. A god that if released, could prove to be an EldritchAbomination for Midkemia.
* Deconstructed ''[[TearJerker horrifically]]'' in ''VideoGame/ArcRiseFantasia''. [[TakeOverTheWorld Prince]] [[ForTheEvulz Wei]][[RageAgainstTheHeavens ss]] accuses the god Eesa of being one of these. The other gods, Real and Imaginal are an OmnicidalManiac and a [[FantasticRacism racist]] [[JerkassGods jerkass]], so the party doesn't really have any other frame of reference... [[spoiler:until it's revealed that Eesa is actually [[BreakTheCutie an emotionally-broken]] WoobieDestroyerOfWorlds. ''How'' she became one is pure TearJerker material]].
* ''VideoGame/DragonQuestVII'' gave us the Dark Lord Orgodemir, the BigBad of the game. He actually poses as [[CrystalDragonJesus God]] at one point!
* Zophar in Lunar2EternalBlue certainly qualifies.
* [[spoiler:The Elder God]] in ''VideoGame/LegacyOfKain'' is eventually revealed to be this in ''Deception'', following truckloads of {{Foreshadowing}} in ''Soul Reaver 2''.
* Tathamet, '''the''' Prime Evil and God of Chaos in the ''VideoGame/{{Diablo}}'' verse. When Tathamet suffered a MutualKill with Anu the God of Order, his body became Hell and his seven heads became the Seven Great Evils, including series BigBad Diablo. In ''VideoGame/DiabloIII'', [[spoiler:it's revealed that Diablo's scheme all along was to reunite the Great Evils into Tathamet reborn (with Diablo at the helm) to end the war between Heaven and Hell once and for all.]]
* The Demon Sovereign from the rebooted ''VideoGame/MightAndMagic'' series (''VideoGame/HeroesOfMightAndMagic V'' and VI as well as ''VideoGame/DarkMessiahOfMightAndMagic'') is the setting's Crystal Dragon Satan equivalent. ''[=HOMM 6=]'' shows that he was a regular demon lord who ascended to the position through politics and conquest.
** While Kha-beleth fulfills a similar role as Satan, the real God of Evil is Urgash, the Dragon of Chaos.
* [[BigBad The Guardian]] essentially took this role in the later ''Franchise/{{Ultima}}'' games.
* The ''VideoGame/{{Painkiller}}'' series started out with {{Satan}} in the role, but he was killed in the first game, and a veritable conga line of successors would pop up in the expansion packs one after the other to claim the title (first Alastor, then [[spoiler: Eve]], then [[spoiler: Samael]]).
* Skorm from ''VideoGame/{{Fable}}'', who the PC can make human sacrifices to. [[spoiler: Doesn't actually exist.]] More important than Skorm is the Corruption, the setting's BiggerBad, as well as the Queen of Blades, who had the position in the setting's backstory.
* In ''VideoGame/EarthBound'', many hints given throughout the game indicate that [[BigBad Giygas]] has essentially become this. [[spoiler: Porky's statement during the final battle even says that he ''is'' evil itself.]]
* Bethrezen and Mortis in the ''VideoGame/{{Disciples}}'' series. Bethrezen is the god the [[LegionsOfHell Legions of the Damned]] worship and Mortis is the goddess of TheUndead Hordes. Bizarrely, they are also the most ''sympathetic'' deities in the setting. The "good" gods are a bunch of JerkassGods whose cruelty towards Bethrezen and Mortis drove them to evil in the first place.
** Bethrezen is the ''creator'' of Nevendaar, the world where everything takes place but was not a deity in his own right, being instead an angel of the elder god Highfather. Both Bethrezen and Mortis are {{Mad God}}s, as is Gallean.
* Demise from ''VideoGame/TheLegendOfZeldaSkywardSword''.
** Majora and quite possibly the Fierce Deity from ''VideoGame/TheLegendOfZeldaMajorasMask''.
* In ''VideoGame/AgeOfMythology'', Greek, Egyptian and Norse mythology are simplified somewhat from the original myths for the sake of the campaigns. As a result, Set becomes this for the Egyptian, Loki for the Norse (especially notable for turning up as an antagonist in person, and serving a much more direct role than Set), and Poseidon for the Greek. However, the ultimate God of Evil is Kronos, from the Atlanteans, since the other three are ultimately subservient to him, and his master scheme of breaking loose and causing TheEndOfTheWorldAsWeKnowIt. All the Titans except Gaia also qualifies, while Cerberus and Ymir are more [[EldritchAbomination Eldritch Abominations]] anyway. The game is notable for averting EverybodyHatesHades though, Hades is somewhat neutral, and his only contribution is helping the heroes escape Erebus when they are trapped there by Gargarensis, the servant of Kronos.
* ''VideoGame/YuGiOhReshefOfDestruction'' has Reshef the Dark Being, who plans to end the world.

[[folder:Visual Novels]]
* Played with in ''VisualNovel/FateStayNight.'' During the Third Holy Grail War the Einzberns tried to guarantee a victory by summoning the [[SuperRinger Zoroastrian god of evil, Angra Mainyu]]. What they in fact summoned was a man whose village had declared him to be [[TheScapegoat the source of all their sins]], his existence being the origin of Angra Mainyu's myth. Having no special abilities he was quickly killed and absorbed by the Grail. But because this man represented the ''wish'' of those ancient villagers for there to exist a singular source of evil, the Grail attempted to grant that wish. Had there been a victor in either the [[LightNovel/FateZero Fourth]] or [[VisualNovel/FateStayNight Fifth]] Grail Wars, he would have become a PhysicalGod.

* The Demon King in ''Webcomic/SluggyFreelance'' is worshiped by his demon followers and was powerful enough to defeat the Goddess of Goodness. He even sealed her away in a plastic baggie, which he kept in his refrigerator.
* "[[Webcomic/{{Digger}} Black Mother]], [[MadnessMantra pass us by! We are not here!]]"
* [[ComedicSociopath Axel]] of ''AnsemRetort'' achieves total inner peace through evil and chaos, a process known as "Reverse Nirvana". This turns him into an evil Bhuddist god with mind bullets.
* In the backstory for ''Webcomic/TheOrderOfTheStick'', we have The Dark One, a goblin warlord and DarkMessiah who -- upon his death -- was [[AscendToAHigherPlaneOfExistence elevated to godhood]] by the [[GodsNeedPrayerBadly belief]] of his followers (specifically, after they went on a year-long slaughter in his name). [[TheDragon Red]][[AntiVillain cloak]] is his high priest.
** Due to the D&D-style setting, there exist various gods belonging to different pantheons, some of which are deemed "evil" gods. Despite this they seem to get along well enough with their good counterparts (as shown by the interactions between Loki and Thor, and in some prequels) with the worst clashes being arguments over what to do in certain circumstances... and for good measure the "good" gods aren't always GenreSavvy.

[[folder:Western Animation]]
* The ''Franchise/{{Transformers}}'' franchise has the Dark God Unicron, the Chaos Bringer and arch enemy of the Creator-God Primus.
* ''WesternAnimation/{{Tutenstein}}'' has one but there's no time to explain.
* Trigon from ''WesternAnimation/TeenTitans'' who, like his original comic book counterpart, is supposed to be the incarnation of all evil.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', the opposed good and evil general principles are presented as being [[ThePowerOfFriendship harmony]] and [[OrderVsChaos chaos]]. Discord is the [[AnthropomorphicPersonification spirit]] of [[ChaosIsEvil chaos and disharmony]] and a RealityWarper at PhysicalGod levels. In the distant past, he ruled the entire country in a state of perpetual unrest and unhappiness. Two whole seasons since his debut, he's still the most powerful entity encountered in the series by a wide margin.[[note]]WordOfGod has apparently hinted at something that may be a BiggerBad even beyond him, but this may no longer count for anything since Creator/LaurenFaust is no longer working on the series and, judging from what she said, she didn't leave them a list of ideas to use later.[[/note]]
* Zarm from ''WesternAnimation/CaptainPlanetAndThePlaneteers.'' He's a spirit of the Earth, like [[BigGood Gaia]], but the two fought eons ago and he went to colonize another planet, which subsequently destroyed itself. He arguably represents [[NatureIsNotNice the "dark" side of nature]], i.e., [[TheSocialDarwinist competition and natural selection]]; his main tactic seems to be supporting dictatorships and spreading conflict.
* Vaatu from ''WesternAnimation/TheLegendOfKorra''; the spirit of chaos and darkness (not just ''a'' spirit, ''the'' spirit), he likes nothing better than corrupting spirits and letting them go on rampages, and [[EvilOnlyHasToWinOnce if he wins]] during Harmonic Convergence then he'll bring about TheEndOfTheWorldAsWeKnowIt.
