Even after being thwarted by the mother goddess Nungeena and her birds, Marmoo attempts to [[TheCorrupter corrupt them]], succeeding with the cuckoos, who on his orders invade other birds' nests and replace their eggs with their own. Feared by the Gamilaaray tribe as a malevolent god, Marmoo is hellbent on the [[TheEndOfTheWorldAsWeKnowIt annihilation of the world]] to spite Baiame and his creations.

* [[BigBad Erlik]] was originally created by [[TopGod Ulgan]] to assist him in shaping the world. Erlik, however, believed himself to be the superior creator, and planned to usurp Ulgan. After accidentally adding the negative features of nature to creation, Ulgan banished Erlik, who then decided to deliberately ruin Ulgan's world to get even. He corrupted Ulgan's perfect life form, humans, adding to them everything negative about human nature, and when Ulgan created [[MessianicArchetype the prophet Maidere]] to enlighten humans, Erlik murdered him, forcing humans to rely on shamans to obtain the knowledge of the gods one tiny bit at a time. In [[EverybodyHatesHades his capacity as God of Death]], Erlik has been known to [[DraggedOffToHell drag human souls to his realm to enslave them]], and it was believed that this would be the fate of anyone who did not first sate Erlik's ego with sacrifices.

* ''Literature/BookOfJudges'': [[EvilOverlord King Abimelech]], the archetypal BastardBastard in literature, [[TyrantTakesTheHelm rose to power]] following the death of his good-hearted father Judge Gideon by [[SiblingMurder having 69 of his own brothers killed]]. As ruler, Abimelech organizes wars of conquest and enacts atrocities to keep the Israelites under his control, most notably having a thousand civilians burned alive to suppress an uprising in Shechem. When the people of Thebez revolt against his cruel rule, Abimelech attempts to raze their shelter to the ground. Vain and petty until the very end, Abimelech, upon being mortally wounded by one of the women he was trying to immolate, orders his aide to impale him with a sword in a futile effort to create the illusion that he died bravely in battle and [[IWasBeatenByAGirl not by the hands of a woman]].

When Mordecai still refuses to bow to him, Haman builds a gallows on which he intends to hang the latter.

* Myth/CelticMythology:
** Irish:
*** [[EvilOverlord Abhartach]] is a chieftain who once lorded over a kingdom in Derry and may have been one of the original inspirations for Count {{Dracula}}. While specific details on the legend may vary, the constant was that Abhartach was a bloody tyrant who mastered [[BlackMagic dark magic]] and was mercilessly cruel to both his people and others, killing his enemies for any slight whether they were guilty or not. He was so feared and hated by those he ruled over, that when Abhartach died, [[AndThereWasMuchRejoicing his people rejoiced]]. Unfortunately, with his dark magic, Abhartach rose as a vampiric creature, visiting his subjects' homes and demanding a bowl of blood from their wrists to feed his thirst. Eventually a rival chieftain was called upon to kill him, but no matter how many times Abhartach was killed, he would rise again to take more victims. It isn't until the chieftain was advised a specific ritual to bind Abhartach forever with the warning to never tamper with his grave lest Abhartach returns.
*** Balor, King of [[TheOldGods the Fomorians]], was a brutal conqueror who was best known for his "[[DeadlyGaze evil eye]]" that could bring horrific ruin and destruction. Sweeping it across entire islands to burn all there, Balor established himself as a brutal tyrant who [[AbusiveParents locked his daughter away]] after a prophecy her child would destroy him. When his daughter became pregnant, Balor [[OffingTheOffspring killed]] several of the resulting [[WouldHurtAChild babies]] with only one, Lugh, surviving to return to bring him down.
** Breton: [[TheDreaded Conomor the Accursed]] is a king made infamous by folklore stories that likely inspired the fairy tale of Literature/{{Bluebeard}}. A feared and brutal king, Conomor is also a [[SerialKiller serial widower]] whose wives have a tendency to vanish. Forcing the marriage of the beautiful Trephine by threatening her lands, Conomor is revealed to murder his wives when they either anger him or fall pregnant, depending on the tale, with multiple dead brides in his past. Conomor attempts to murder Trephine for violating his orders, and after his just death, he is [[BarredFromTheAfterlife too evil to enter the afterlife]], becoming a murderous [[OurWerewolvesAreDifferent werewolf]].
** Scottish:
*** [[AristocratsAreEvil William de Soulis]] was the hated lord of Hermitage Castle. Seen in folklore as a [[HollywoodSatanism monstrous Satanist]] who worshiped the devil by kidnapping [[WouldHurtAChild children]] and butchering them en masse in [[HumanSacrifice dark sacrifice]], de Soulis summoned the wicked Robin Redcap as his {{familiar}} to torment countless innocents while de Soulis raped, tortured and killed at will.
*** [[ImAHumanitarian Sawney Bean]], born Alexander Bean, started out as the son of an honest, hardworking man, but preferred a life of "freedom", as opposed to following in his father's footsteps. He would later take a wife in a like-minded woman named Agnes, where they made a home in a cave and lived a life of vice; mainly [[CannibalClan cannibalism]] and [[VillainousIncest incest]]. Their union produced dozens of children and subsequent grandchildren from [[InbredAndEvil inbreeding]]. Over the years they would kill, [[BanditClan rob]], and cannibalize thousands of people, and in turn would get innocent people lynched when they were blamed for the murders. Sawney and his family were revealed to the world when they attacked a married couple on their wedding night, and in the ensuing manhunt, their cave was found decorated with the bones, body parts and possessions of their victims. While there are slight variations to the story, a constant was the King orders Sawney and his family to be inhumanely executed without a trial, as they were no longer considered human at this point.
*** [[AxCrazy "Black" Agnes Douglas]] is Sawney Bean's equally heinous [[UnholyMatrimony wife]] and partner-in-crime. Even before she met Sawney, she was allegedly a [[WickedWitch vicious witch]] who practiced [[BlackMagic dark magic]] and even [[TheCorrupter corrupted Sawney]] into villainy in later versions of the story. After marrying Sawney, Agnes would live with him in a cave, having children with him and encouraging incest with their children to produce more offspring. Agnes would assist Sawney in robbing, killing, and [[ImAHumanitarian cannibalizing]] thousands of people and decorating their cave with the possessions and body parts of their victims.
* English Folklore:
** [[WickedWitch Black Annis]] is a fiendish creature known through Leicester(shire) as a [[WouldHurtAChild predator of children]]. Lurking in the shadows, Annis relishes the fear of her prey before hunting them, taking the children she finds, draining their blood and [[FlayingAlive flaying them]] with her claws before [[ToServeMan feasting upon them]] and [[GenuineHumanHide wearing their tanned skins]] as her trophies.
** The Kuri is a malicious [[OurGoblinsAreDifferent goblin]] that haunts the graves of those who have died in the wilderness, latching itself upon any traveler who disturbs it and [[MindRape tormenting]] them for a lengthy period of time. After [[DrivenToMadness driving the victim to madness]], the Kuri falsely promises to leave the victim be in exchange for returning it to its grave, leading to the victim's death by exhaustion and the Kuri [[DraggedOffToHell dragging their soul to Hell]].
* Orcadian Myth: The {{Nuckelavee}} is the evilest creature on Orkney. A twisted beast who [[FantasticRacism despises humanity]], the Nuckelavee rises from the sea to stalk the land, destroying crops and spreading drought and [[{{Plaguemaster}} plague]], seeking to [[KillAllHumans kill every human]] it can. Those it finds are dragged to the seas or rent apart, with the Nuckelavee glorying in their deaths. Confined for part of the year, the Nuckelavee seeks only to torment and kill all the innocent it can, doing so [[ForTheEvulz for the sheer simple pleasure of evil]].

Using the bones of her slaves' children in Voodoo rituals, she would brainwash her slaves into complacency, taking any who rebelled into her basement where she would [[ATasteOfTheLash torture them to death with whips]], taking pleasure in her actions. Even after being killed, it's said that her ghost still continues to haunt Rose Hall.

* Atreus, grandson of Tantalus, was the king of Mycenae, the son of Pelops and Hippodamia, and the father of Agamemnon and Menelaus. Accounts vary, but in some cases he, and his brother Thyestes, [[SiblingMurder killed his half-brother]] out of jealousy. When his wife, Aerope, helped Thyestes take the throne, Atreus killed Aerope, and with the help of Hermes and Zeus, retook the throne. Despite this, upon learning of Aerope's adultery with Thyestes, he went further with his revenge, killing Thyestes's [[WouldHurtAChild young sons]]. During a supposed reconciliation dinner, Atreus then [[FamilialCannibalismSurprise tricked Thyestes into eating the flesh of his own sons]] and taunted him with their hands and feet, thus violating ''[[SacredHospitality xenia]]'' like his grandfather. He then forced his brother into exile for eating the flesh of a human, despite him being unaware of that. Following Thyestes's capture by Agamemnon and Menelaus several years later, Atreus ordered seven-year-old Aegisthus, the son of Thyestes and Thyestes's own daughter, to kill Thyestes. Even in [[RoyallyScrewedUp a family notorious for its multiple cases of incest, violence, and revenge]], Atreus stood out by the sheer violence he was capable of and the joy he found in hurting his brother, all for the sake of revenge.
* [[ZeroPercentApprovalRating Lycaon]] is the tyrannical ruler of Arcadia. A cruel, bloodthirsty king hated by own people for his vicious barbarity, Lycaon was angered when his citizens celebrated Zeus's visit to his city. Determined to prove to his people that the gods would never visit them, and are therefore unworthy of their worship, Lycaon offered Zeus a room for the night, plotting to murder him in his sleep. He also sought to test Zeus's divinity, by serving the god human flesh at dinner. [[OffingTheOffspring Butchering his own son]], Lycaon roasted his flesh to serve it to Zeus, [[ImAHumanitarian dining on some of it himself]]. In some versions of the tale, he even sacrificed a newborn baby before Zeus just to see how he would react. Disgusted by Lycaon's brutality, Zeus transforms him into the [[FirstOfItsKind first werewolf]], but noted that the change only altered his outward appearance as he was always a wild monster. Even after his death, Lycaon's wanton hunger for blood and flesh would live on in his many descendants who owe their lycanthropy to him.
* [[SerialKiller Sinis, Sciron, and Procrustes]] are three depraved bandits and killers, with particularly [[CruelAndUnusualDeath cruel methods]] of murder, who Theseus encountered on his journey to Athens. Sinis lured in travelers with promises of hospitality only to turn on them and tie them to trees to be painfully ripped apart. Sciron was an elderly man who tricked travelers into washing his feet, only to kick them off a cliff to be eaten alive by a giant turtle lurking far below. [[BadSamaritan Procrustes]] was a blacksmith and innkeeper who offered promises of rest at his {{inn|Of No Return}}, yet would violently stretch those too small to fit in his bed(s) and hack off the limbs of those that were too tall. These three men were all considered particularly vile for violating the concept of ''[[SacredHospitality xenia]]'', perhaps the greatest taboo in the ancient Greek world.

[[folder: Myth/Egyptian Mythology ]]

* [[OmnicidalManiac Apep]], more widely known in the West by his Greek name, [[TheDreaded Apophis]], was the Egyptian [[GodOfEvil god]] of [[GodOfDarkness darkness]], [[GodOfChaos chaos]], and [[DestroyerDeity destruction]]. Residing in the Underworld, Apophis took the form of a colossal snake, and every night, would attempt to devour the sun god Ra, as he made his way through the land of the dead, hoping to leave the world without light or life. During the day, while Ra was in the sky, Apophis would feed on those dead souls who were not properly protected against him, leading to their complete obliteration. His motives for doing so were that, as a primordial being associated with the dark, he hated the fact that there was a sun, or life on Earth, and aimed to go back to the way things used to be. He was also the leader of armies of demons, and sought to subvert mortal confederates into aiding his nihilistic agenda. Reviled by all the other deities, even Set, and universally loathed in Egypt, Apophis was the only god to have the distinction of never being prayed to. Instead, temples and ceremonies were set up to pray against him.

Arriving in the village of Wittlich, Schwytzer and his men broke into a local farmhouse for food and supplies, killing the farmer and his sons when they are discovered and [[CruelAndUnusualDeath crushing the skull of the farmer's wife]] afterwards. Cursed by the farmer's wife to become a werewolf during the full moon, Schwytzer embraced his darker impulses, leading to his men leaving him in disgust, and began to [[RapePillageAndBurn pillage local villages and farmsteads]], leaving a trail of dead men and cattle in his wake. Schwytzer would use his werewolf transformation to kill and rape innocent people and women, [[RapeIsASpecialKindOfEvil forcing himself upon girls]] like Elizabeth Beierle to satisfy his sadistic urges.

* [[NotQuiteTheAlmighty The Demiurge, or Yaldabaoth]], is a take on the [[Literature/TheBible Old Testament God]], used to explain the Problem of Evil. A [[GodIsEvil malevolent false god]], Yaldabaoth is the source of humanity's sinful nature and all the misery, who takes joy in human evil, so long as he's worshiped as the TopGod. Yaldabaoth created the physical realm, and humanity, as debaucherous and mindless creatures, before the higher gods took pity on them and granted them knowledge and souls, thus giving access to the true spiritual world. The materialistic Yaldabaoth would prefer to manipulate the world in wickedness, keeping humanity in the dark of the spiritual world. This puts him in direct conflict with his mother Sophia, who in some versions was [[{{Matricide}} destroyed by her son]], with her remnants becoming humanity's souls. While MadeOfEvil in some versions, other versions are just pure evil.

* [[EvilUncle King Kamsa/Kansa]], the tyrant ruler of the Vrishni Kingdom, who [[TheUsurper overthrew his father to get the position]], uses his power to punish those he sees as lesser. When he hears of a prophecy that the 8th children of his cousin Devaki will kill him, Kamsa imprisons her and her husband and [[WouldHurtAChild murders all their children, as well as any child born within the past 10 days]]. Hearing of Krishna & Balarama's survival, Kamsa sends out multiple demons in various attempts to kill them, each resulting in several other deaths. When the two of them try and stop Kamsa, he says he'll have everyone in Mathura killed if Krishna doesn't surrender.
* Putana, the "[[WouldHurtAChild Killer of Infants]]", is a [[OurDemonsAreDifferent Rakshasi]] known for killing infants by poisoning her breast milk and killing them when they feed, having done this to countless infants in the past. When King Kamsa summons her to kill the infant Krishna, Putana disguises herself as a beautiful woman in an attempt to kill him. After Krishna sucks her life force out, Putana reveals her demonic form and attempts to destroy the town of Vraj, managing to turn the surrounding forest to dust before being slain.

* [[TheVamp Tamamo-no-Mae]] is a wicked [[AsianFoxSpirit fox spirit]] reputed as one of the three most fearsome {{Yokai}} of Japan, seducing and poisoning the retired emperor before being exposed and killed, her death cursing Japan to a brutal war. Later versions equated Tamamo with [[Literature/FengshenYanyi Daji]] and Bāo Sì of China and the Indian legend of Kalmashapada, seducing and [[TheCorruptor corrupting]] kings into savage tyrants, torturing and slaughtering countless innocents, and kicking off wars. While some versions of her posthumously repent, others double down on their villainy and don't let even death stop them from bringing chaos to the world.
* The man who would become the {{Youkai}} Wanyūdō was once a tyrannical daimyō known for mistreating his subjects, often having them drawn on the back of an Ox cart. After his assassination, the daimyō was reborn as Wanyūdō, a [[OurSpiritsAreDifferent wrathful spirit]] in the form of a flaming cart wheel. Usually sighted in urban areas after dark, Wanyudou ruthlessly [[CruelAndUnusualDeath runs down and dismembers]] anyone he comes across, [[DraggedOffToHell dragging their souls to Hell with him]]. One legend tells of a mother who glimpsed the creature through her window. Wanyūdō spared her, telling her to tend to her child...only for the woman to discover the [[WouldHurtAChild infant's limbs scorched off,]] a sick reminder that Wanyūdō is just as sadistic in death as he was in life.

* [[OmnicidalManiac Settut]], or [[WickedWitch Settuta]], also known as Immas n Tadwit, the "First Mother of the World", is the cruel [[GodOfEvil Goddess of Evil]] and [[GodOfChaos Chaos]]. Once a benevolent creator goddess, she became bitter and jealous of the world and dedicated herself to destroying it after learning she was sterile, sacrificing countless women and children in an attempt to make herself fertile, and creating the stars out of their bones when that failed. Settut created destructive storms, floods, and eclipses and [[TheCorrupter introduced mankind to envy and greed]], leading them to commit acts of war, slavery, theft, and murder against each other. Along the way, Settut created her palace of the bones of her many victims, counting each one every day. Resentful, sadistic, and with a [[WouldHurtAChild preference for targeting children]], Settut is responsible for all the misery of the world and is gleefully excited about the prospect of the day when [[TheEndOfTheWorldAsWeKnowIt the world will be consumed by the underworld]].

* UsefulNotes/{{Zoroastrianism}}: [[GodOfEvil Angra Mainyu]], known by his Persian name of [[GodOfDarkness Ahriman]], is the EvilTwin of creator god Ahura Mazda, and [[TheAntiGod the antithesis of everything good and just]]. Declaring that "[[CardCarryingVillain it is not that I cannot make anything good, but that I will not]]," Angra Mainyu sought to prevent Ahura Mazda from creating life in the first place, by slaying the primal bull, his first creation. He seduced the daevas (demons) away from Ahura Mazda, transforming them into spiteful beings living only to spread fear and hatred. When Ahura Mazda created sixteen lands, Angra Mainyu responded with sixteen scourges, including old age, disease, war, vice, and death. He created the monster Aži Dahāka, destined to slay one-third of the Earth's population, and turned him loose in the world. He made two separate attempts at destroying the Earth's water supply and leaving all creation to die of dehydration. He made Jeh, the primal whore, so that women would suffer from menstruation, birth pangs, and mistrust from men. He tried to coerce Zoroaster into coming over to his side, and then set the daevas upon him when he would not. Responsible for the very existence of evil, Angra Mainyu works to seduce men and women away from Ahura Mazda, so they might join his campaign for control of reality. Hating everything good and just, and angry that he is not the one who created everything, Angra Mainyu's ultimate goal is the [[OmnicidalManiac annihilation of the universe]].

* Romani folklore is plagued with [[EldritchAbomination horrific monsters]] that embody every disease known to man, and this father-son duo is responsible for creating them:
** The King of the Loçolici ({{humans|AreTheRealMonsters}} cursed by {{Satan}}) once took a fancy to Ana, the queen of the [[OurFairiesAreDifferent Keshali]]. Rejected by Ana, he responded by hunting down her people and devouring them. When Ana agreed to marry him to save her people but still refused to have sex with him, the King drugged her and [[RapeIsASpecialKindOfEvil raped]] her. Goaded by his son, Melalo, he continuously forced himself on Ana, spawning horrible monsters that have plagued humanity ever since. Tired of this, the Keshali baked him a cake with dog and cat hairs that impregnated him with Poreskoro, the embodiment of TheBlackDeath. With this attempt on his life, the King decided to divorce Ana, but only on the condition that she kept herself alive by drinking the blood of three of her own kind for all eternity, as once she dies, he will kill all Keshali once and for all.
** [[AnimalisticAbomination Melalo]] is a two-headed [[FeatheredFiend bird]] born from the [[ChildByRape unholy union]] between the King of the Loçolici and Ana. He goaded his father into raping his own mother several times, creating monsters that cause diseases among humanity. He even took one of these, the hagfish-like Lilyi, as his own wife, breeding more disease demons into existence.
