""The people of the world are builders. But look into their hearts, and you will find they also have the power to destroy. I am that power! I am destruction! And I WILL destroy you." - Makuta Teridax, Lego Bionicle." It doesn't matter what other media exists, for it will almost guarantee that there will be atleast a few of these inhuman beasts wreaking havoc. Oh yes, the land of fiction is a truly dangerous place.

Mythology and Religion

 * Greek-Roman myth is replete with examples of mortals who tried to outsmart the gods and paid for it. Yet none of them found as disgusting a method, or deserved their resultant punishment, as these people did:
 * Tantalus, a Greek king who was a favourite guest and host of Zeus', proved that familiarity breeds contempt. Deciding that the gods were fools rather then omniscient beings, Tantalus set out to show that they could not even tell what they were being served for dinner, let alone comprehend the secrets of the cosmos. Murdering his own son, Pelops, Tantalus had him boiled, and served to the gods as the main course at dinner. By tricking the Olympians into eating their host's child, he sought to demonstrate that the gods were utter imbeciles. Instead, he proved that he was a relentlessly vile person and that even Olympian gods have standards. When his ploy was uncovered, Zeus both resurrected Pelops and trapped Tantalus in an Ironic Hell, cementing cannibalism, the slaying of one's own children, and the mistreatment of guestsnote as major taboos in Greek culture.
 * Following Tantalus' bad, bad example is Lycaon, tyrant of Arcadia, and the first werewolf. Appearing in several compendiums of myth from the time period, the most infamous version of Lycaon's story appears in Ovid's Metamorphoses. A cruel, bloodthirsty ruler, Lycaon was angered when his citizens celebrated Jove's (Zeus) visit to his city. Determined to prove that Jove was not really a god, and was therefore unworthy of their worship, Lycaon offered Jove a room for the night, plotting to murder him in his sleep. He also, like Tantalus before him, sought to test Jove's divinity, by serving the god human flesh at dinner. Butchering a hostagenote, Lycaon roasted his flesh, ate some of it himself, and placed it on the table before Jove, who reacted in outrage and disgust, cursing him with lycanthropy. Watching the newly lupine tyrant slaughter a herd of sheep, Jove noted that Lycaon's nature had not changed; he was simply now as savage on the outside as he had always been on the inside.
 * Erlik, the Big Bad of the Mongolian and Siberian pantheons, was originally created by 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 the prophet Maidere to elighten humans, Erlik murdered him, forcing humans to rely on shamans to obtain the knowledge of the gods one tiny bit at a time. In his capacity as God of Death, Erlik has been known to drag human souls to his realm to enslave them, and it was believed this was the fate of anyone who did not first sate Erlik's ego with sacrifices.
 * Haman, from the Book of Esther of the Judeo-Christian Myth. A Treacherous Advisor who plots the genocide of the Jewish people simply because he felt offended by one Jew's refusal to bow to him, he is arguably the worst human villain in Biblical literature. And his Xanatos Backfire at the gallows he had planned for Mordecai was also quite spectacular, especially after he went to King Ahasuerses to talk him into having Mordecai hanged (never getting around to it due to an unrelated matter) and wound up instead feting Mordecai for his heroism in saving the king's life from a couple of rebellious eunuchs--which wound up being the point where even his wife told him to his face that his obsession with killing the Jews would become self-destructive real soon. Naturally, he ignores her and goes ahead with his plans to wipe out the Jews. His name has become a watchword for anti-Semitism and he is viewed in rabbinical tradition as an archetypal evil figure.
 * Egyptian Mythology has Apep, more widely known in the West by his Greek name, Apophis, the Egyptian God of Evil, who was associated with darkness, chaos, and 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, including Set (who eventually took on the role of God of Evil), 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.
 * Zoroastrian Myth: Angra Mainyu, alias Ahriman, is the Evil Twin of creator god Ahura Mazda, and the antithesis of everything good and just. Declaring that "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 annihilation of the universe.

Urban Legends

 * Japan has various urban legends with ghosts, monsters and demons that are depraved and psychotic beings out for blood and death.
 * Kuchisake-Onna, known as the Slit-Mouth Woman, is the spirit of a Samurai's wife who roams the streets of Japan wearing a surgical mask. In life, she was known for being a beautiful but unfaithful wife who would use her beauty to get away with her infidelity and sins, only to be caught by her husband and killed by slicing her mouth open. Coming back as a wrathful ghost, Kuchisake-Onna preys on children due to them being an easy target and asks them the question of if they look beautiful. If the child says no, she will stab them to death with a pair of scissors but if they say yes, she removes her mask revealing her disfigured mouth. Saying no makes her kill the child and saying yes will make her spitefully give her victim the same disfigurements. A cruel, sadistic child killer who murders out of spite and rage, Kuchisake-Onna is one of Japan's vilest ghosts.
 * Aka Manto is a masked spirit that haunts bathrooms and is a sadistic murderer. Aka Manto asks the victim if they want red paper or blue paper, picking red will make him violent murder his victims and drench them in blood while picking blue with make him strangle or bleed the victim dry and turn their skin blue. Asking any other colour will result in Aka Manto dragging his victims to hell. Aka Manto has no real motivation other than pure sadism and spite.
 * The White Death from Mexican and Hispanic folklore is a nihilistic undead entity of a girl who hated life so much that she killed herself and everyone who knew of her existence. She now exists within a state of death and non-death wandering the earth to find those who have heard of her. She will come to the victim's house and knock on their door, each time represent what she will take from them. She knocks once for you skin, which she’ll use to patch her own decaying flesh. Twice for your hair, which she’ll gnash between her teeth. Three times for your bones, which she’ll fashion into clubs. Four times for your heart, which she’ll tear out of your chest. Five times for your teeth, which she’ll polish and keep in a box. Six times for your eyes, which she’ll pluck out one by one. Seven times for your soul, which she’ll swallow whole.
 * Baba Yaga from Russian folklore is an old witch who feasts on the flesh of children who come to her house with chicken legs. Baba Yaga will either adbuct children or lure them to her house where she will manipulate or deceive them long enough for her to attack and eat them. While some versions of the tale have her portrayed as a trickster or even a sympathetic witch, this incarnation of Baba Yaga is a child murdering cannibal with a sadistic streak.

Roleplay

 * Dino Attack RPG: Nearly every villain has some redeemable trait... and then there's these guys.
 * The Brickspider Bot v1.0. Simply put, the Brickspider Bot is a cold-blooded killer, with quite a body count during the battle for LEGO Island. The Brickspider Bot also assisted Dr. Rex in leading the Dino Attack Team to the trap in Quadrant 14, which took even more lives. It was also noted that the Brickspider Bot is a grave robber who picks apart dead bodies to find ways to improve itself. It was created to be a mere mook, but Evil Ogel and General Evil realized that it was too intelligent and too evil, and so they knew it had to be destroyed. Even Cyber-Bully was disgusted by the Brickspider Bot's presence. The Brickspider Bot feels sadistic pleasure in torturing and terrorizing its victims before killing them in cold blood. The sole reason the Brickspider Bot wants to see the apocalypse happen is because it revels in the death and destruction it will cause, i.e. In Love with Your Carnage. Never portrayed sympathetically, and ultimately killed by the heroes.
 * Michelle Glados is willing to kill a world's population in a horrible apocalypse that she helped to bring about... you know, For Science! The fact that she suggests this so emotionlessly only makes it worse; although she rarely shows emotion, she feels no regrets over what she has done, and her emotionless exterior actually masks a sadism rivaling that of Loop and the Brickspider Bot. Otherwise, one might argue that her lack of caring only makes her an even greater monster. She knowingly took a group of Dino Attack agents, disguised as her own mooks, and sent them to the front lines of the battlefield where they were shot and killed by their own teammates. Then, she activated poisonous gases to treat the survivors with a slow, agonizing death. But the greatest Player Punch of all was when she killed Amanda Claw and Trouble, two beloved long-runners of the Dino Attack RPG, which numerous players attested to having radically altered their perception of the RPG as a result. Her presence usually elicits complete disgust from those around her. Even if she does have a Freudian Excuse in the form of a Friendless Background, that's no excuse for her behavior today, as called out by Frank Einstein. When Glados and her fellow scientists realized that they were being manipulated by the Darkitect all along, they were all given a chance of redemption. Most of the other scientists took that chance and, by the end of the final battle, were fighting alongside the heroes. Glados did not. In fact, she barely even acknowledged the possibility that she could have redeemed herself, instead choosing to continue pursuing her own goals up until her death.
 * Baron Typhonus, the Darkitect, is considered to be on nearly-Eldritch levels of unspeakable horrors. He wants to destroy the planet... and then, from there, the rest of the universe. Being the RPG's only Omnicidal Maniac, he is frequently a target of Even Evil Has Standards and Evil Versus Oblivion. He actively plays with the minds of numerous characters, toying with their emotions to increase their suffering or bend them to his will. He has even brought peoples' worst fears to life in some of the cruelest ways possible. One of the worst things he has done on-screen is his Divine Intervention, saving Dr. Rex from death, but in doing so, leaving him in a state of endless pain and agony while reducing him to little more than a puppet that he could control, forcing him to keep fighting a battle he no longer wanted to fight. That's right. He turned Dr. Rex, who was a monster in his own right, into The Woobie. He has no regret or remorse for anything he does. When his minions, nothing more than tools to accomplish his goals to him, outlive their usefulness, he offs them without a single second thought. In fact, throughout everything he does, he remains arrogant and smug about it, enjoying seeing the pain he inflicts upon others. While he cannot be killed, his presence is indefinitely banished from Earth, which was the only way the RPG could have a remote chance at a happy ending.
 * Global Guardians PBEM Universe: The worst by far is The Blood Red King (the Anthropomorphic Personification of Terror), who, on a lark, once invaded the maternity ward of a Belgian hospital and suffocated all the babies whose name began with an "odd-numbered" letter (A = 1, C = 3, and so on). He once forced a crusading televangelist to rape, strangle, and dismember his own teenage daughter during a live television broadcast because he didn't like the man's hair.
 * The Insane Quest of Unfathomable Randomness: Sola Soulhawk has attempted genocide, destroying worlds, murdering her foes' closest friends simply to mess with her foes, Cold-Blooded Torture, and a creepy fascination with her cousin that combines Incest Subtext with murderous intent.
 * Mass Effect Forum RPG: Tiraz Malkizan was, throughout his life, only ever interested in two things: Gaining money and power, and hurting people . Never a moral Turian to begin with, he committed his first murder at the age of 16 when he didn't want to share the loot of a robbery with his partner. Later on he decided that he could make far more money by becoming a Dirty Cop than with petty crime. For that end, he manipulated his two naive colleagues Beyo and Javed to use dirty methods (mostly blackmail and torture) to gather information faster and often framing innocent parties, all under the pretense of doing the work that others are afraid to do for the greater good. His most heinous acts during that period were the murder of an investigating co-worker and the brutal raping of Luceija Ascaiath, which he recorded for his own amusement. After being exposed and confronted by his colleagues, he grabbed off all the money they ever made and ran off to become a powerful crime lord, now fully embracing his savage nature with delight. Him raping and cannibalizing an Asari Justicar to death (after throwing her companion out of a window) and butchering his completely loyal assistant for saving him a few moments later than he ordered are just a few examples of why he is still considered the absolutely worst person this RPG has ever spawned, despite being dead for over 5 years now.

Theme Park

 * The Tooth Fairy is the main antagonist of the haunted attraction of the same name at Knott's Scary Farm. She/he is a horror beyond conception that has existed since the beginning of time. She/he is obsessed with teeth and will break into the homes of children who have just lost teeth to violently kidnap them and take them to their realm. There, she/he and their minions will brutally and painfully imprison and torture them, ripping out their intestines, bones, organs, and teeth until they are dead. She/he commands their minions to make things as horrific as possible, using massive drills, saws, hooks, and knives to mutilate and torment the innocent children. Her/his realm is filled with torture equipment and things she/he has stolen, including the children's toys and the coins their parents left under their pillows. She/he decorates the realm with pinned butterflies, jars of children's organs, teeth, and stretched-out human skin. She/he also kidnaps some adult victims to torture and forces them to watch the horrors, even making a hallway from severed mouths, one of which is still screaming, and she/he taunts the guests and the families of the victimized children before going back to the human world and attacking another child in front of guests.

Theater

 * William Shakespeare has produced timeless works with quite the incredible and diverse output. From some of his plays have come villains who are impressive in their depravity centuries later.
 * Richard III is one of the most famous examples of a Historical Villain Upgrade in English drama. Richard informs us early on that he is determined to prove a villain and ruin the day for everyone else. To that end, he seduces Anne Neville, whose noble husband he himself murdered, with every intent of discarding her later. He has his brother George, Duke of Clarence, sent to the Tower of London and murdered, drives his older brother King Edward IV into an early grave and has Edward's two young sons imprisoned in the Tower of London, before having them murdered. He poisons Anne herself, and even begins having his allies killed. On the night before his battle with Henry Tudor, he is visited by the spirits of his victims, who tell him to despair and die. Richard is left alone, deserted by all, and at the end, he admits that even he has nothing but hatred, with no love even for himself.
 * Iago from Othello is one of the most (in)famous in history. Tricks his best friend into killing his own wife and then committing suicide, leaving a path of bodies in his wake (including his former accomplice and his wife, who angered him) for what many think was no reason whatsoever. And people still called him "Honest Iago" until the last couple of pages. Iago is so evil that, by the end of the play, many audiences feel that his ultimate fate (being dragged off to be tortured to death) is too good for him.
 * Aaron the Moor provides a classic example of an unrepentant monster. Throughout the play Titus Andronicus, he engineers various acts of malice and villainy. Before his death at the play's end, he recounts a litany of atrocities he has committed and claims, "If one good deed in all my life I did, I do repent it from my very soul." This could suggest that he regrets even his sole Pet the Dog quality, his care for his infant son, meaning he dies rejecting any and all redeeming qualities.
 * The Lion King musical: Scar commits the same crimes that his movie counterpart did and goes beyond that. During the musical, Scar became more and more paranoid as time went by and he also felt that he was being tormented by his older brother even in death. Unwilling to admit that he was terrible at governing the Pride Lands, he instead condemns all his subjects to death so that he wouldn't have to accept that maybe he wasn't as good at being a king that he thought he would be. He also attempted to force himself onto Nala (a scene cut from the film), which becomes even more disturbing in hindsight considering that he tried to have her killed along with his nephew when they were children. Scar is ultimately no more than an egotistical, treacherous, and murderous feline.
 * In Heinrich Marschner's opera Der Vampyr, an adaptation of John Polidori's short story "The Vampyre," Ruthven is a Satan worshipper, who must drink the blood of three women over a twenty-four hour period or forfeit his soul to Hell. He kills a girl named Janthe, then fakes his death after her father shoots him, making his friend Aubrey, who he once saved, keep his being a vampire a secret. The next day, Aubrey finds Ruthven has hypnotized his Love Interest Malwina's father into engaging them; he has also begun preying on a girl named Emmy. Ruthven kills Emmy, handing her soul over to his masters, then goes through with his plans to marry Malwina, while using his supposed friendship with Aubrey and the oath that the latter swore, to keep him from warning her and her father that Ruthven will kill her. In the end Ruthven is struck down by his own masters, moments before he can kill not only Malwina, but Aubrey too, whom he regards as a traitor for trying to stop Ruthven from killing his girlfriend.
 * Tosca: Baron Vitellio Scarpia is the head of the police who relentlessly hunts down those deemed as "traitors" and subjects them to torture and execution. When he captures the painter Mario Cavaradossi, he decides to use the man as leverage to possess his sweetheart Floria Tosca. He has Mario brutally tortured, and convinces Mario that Tosca betrayed him to drive a wedge between the lovers. He then proceeds to offer Tosca Mario's safety if she sleeps with him, horrifying her. He promises to spare Mario if she does so, arranging a fake execution. However, even after Scarpia's death it is revealed he had no intention of honoring his word: the execution is real and Mario dies anyways. A venal hypocrite hiding behind his sanctimony, Scarpia glories in the fear he spreads over Rome and believes the best way to possess a woman is by force.

Animation

 * An Indian cartoon called Krishna Auns Kans gives us two of them:
 * King Kans is a brutal tyrant and warlord who starkly believes it is his right to take whatever he pleases, at the expense of the kingdom. While prince, Kans devastated villages, brutally killing its inhabitants and forcing others into slavery. When Kans hears of a prophecy that the eighth son of his beloved cousin Devaki will put an end to his reign, he makes it his foremost mission to kill him to end the threat to his rule. He is offered the chance to repent of his evil, but refuses. He revokes his former love for Devaki and imprisons both her and her husband Vasudev on the day of their wedding, and murders their newborn children so that they won't grow up to oppose him, also executing anyone who sympathizes with the two. When Devaki gives birth to Krishna and he is hidden away in a village, Kans summons demons to kill him, even allowing the witch Putna to slaughter infant children by the hundreds just to ensure Krishna's death. After a decade passes, Kans finally summons Krishna to a gladiatorial battle to finish him once and for all. Believing himself superior to all beings, Kans was a monstrous ruler who caused the deaths and suffering of thousands of people.
 * Putna is the first demon summoned by Kans, and one of the most vile. Dealing in the black arts, Putna takes pride in her evil and cruelty. She torments the other demons in the underworld, burning and melting them on a whim, all the while gloating of how she has killed many humans. When summoned by Kans to kill Krishna, Putna is piqued, desiring the deaths of thousands of children. She only agrees to the deal when Kans appeals to her by demanding that every infant boy born in the last ten days be killed. Putna then terrorizes the kingdom, gleefully murdering every infant she sees. When she finds Krishna, she transforms into a beautiful woman and tries to feed him poisoned breast milk. Among a colony of demons, Putna surpasses the others in sheer cruelty, and the other demons are both mesmerized by and terrified of her.
 * The Korean-Spanish CG Animated Series Eon Kid gives us these examples:
 * The General is the sociopathic Cyborg who is responsible for the post-apocalyptic state of the Earth throughout the series, and easily the most powerful being in the story. Developed a century ago to fight against an army of beings called the Gigantors, the General quickly developed a god complex and obsession with destiny, and led an uprising against humanity to Take Over the World, leading to mass destruction and chaos. Though seemingly defeated by the great hero Eon, the General was rebuilt 100 years later by his servants, and immediately restarts his campaign for conquest by dispatching dozens of CDF soldiers before reactivating one of the Gigantors. Using the Gigantor, the General crushes all in his path, planning to annihilate all those who stand against him, and coldly executes his loyal Dragon, Khan, for expressing disgust at the General's disregard for the mass casualties he plans to cause. When Marty, the last descendant of Eon, confronts him, the General attempts to painfully kill the boy while forcing his friends to watch, even mind-controlling one of them into attacking Marty for him, before finally losing all his previously smug composure to rant about his plans to plunge the world into darkness to fulfill his destiny. Vicious and cruel beyond compare, the General was feared across the world for good reason, and stamps himself in Earth's history as the greatest threat it ever faced.
 * Dr. Chen, one of the General's two Co-Dragons alongside Khan, is a diabolical genius bent on reviving the General and taking over the planet alongside him. Originally a high-ranking CDF scientist who was demoted for his unethical experiments, Chen betrayed humankind to rebuild the General and began collecting his scattered parts through any means necessary. To ensure the General would go unopposed when revived, Chen and Khan order the entire Eon family bloodline exterminated, leading to the deaths of numerous innocents, and Chen regularly orders the deaths of innocents throughout the series. After manipulating the arrogant Von Rhyner into reconstructing a Gigantor for him, Chen orders the man and his entire staff to be disposed of, and, once the General is revived, Chen gleefully pilots the Gigantor to destroy any opposition to the General, and tries to murder the young girl Ally when she attempts to shut down the mechanical monstrosity. Dr. Chen was a slimy scumbag who was willing to doom countless innocents out of nothing but ego and scientific curiosity, and is responsible for most of the evil in the series.
 * Scar, despite his limited appearances, sticks out as one of the series's wholly wicked characters. A twisted madman who serves the General simply to get to hurt people, Scar was the one commissioned to wipe out the Eon bloodline, and he gleefully hunted down each and every member of the family and slaughtered them, nearly claiming the life of a then-infant Marty as well. In the present, Scar attempts to torture a captured prisoner for information, and later tracks down a now preteen Marty, at which point he confronts Gaff, the Eon family guardian, whom Scar viciously mocks regarding his massacre of the Eon bloodline, even fondly recalling their screams as he cut them down. When he eventually confronts Marty by slaughtering his way into a hospital, Scar continues his boasts of glee at killing the boy's family, and implores the boy to stay conscious as he assaults him, noting it won't be as fun to kill him if he's not awake. Though a minor villain in the grand scheme of things, Scar stood out among his fellow villains as the only purely sadistic individual who regarded killing and hurting others as rewards in themselves.
 * Sky Blue: Commander Locke is the ruthless head of security of Ecoban, introduced working the Marrians to death in terrible conditions. When a disaster occurs, Locke disengages a part of the rig, killing a large amount of innocent workers. When a foreman tries to stop Locke, Locke executes him on the spot and tells his subordinates that it's fine because the man drew a knife on him first. Locke begins ramping up the oppression, taking his men to kill protesting Marrians and finally initiates Operation Marr to exterminate most of them except those he'll spare to be enslaved to work for Ecoban. When he returns to find the heroine Jay trying to sabotage the city's unfair system, Locke gleefully attempts to shoot through his own second-in-command Cade to kill her, grinning all the while.
 * In the Chinese animated film Monkey King: Hero Is Back, Hun Dun (or Hundun), the leader of the mountain trolls, is an alchemist practitioner searching for eternal life. Tasking his minions with kidnapping children, Hun Dun intends on burning the captured children alive in an alchemy furnace and extracting their life essences, thereby creating an elixir to extend his own life. After succeeding at capturing the young girl, Hun Dun, angered by Liuer's intrusion in his plans, seizes the young boy and strangles him to the point of unconsciousness and later tries to kill him with several blasts. Transforming into a nightmarish monster upon acquiring energy from the solar eclipse, Hun Dun throws a boulder at Liuer when Sun Kwong was reaching out to grab him.

Multimedia

 * Bionicle has had a surprising amount of these for a Lego-based franchise:
 * Makuta Teridax is the Big Bad of the franchise as a whole, and is responsible for nearly every bad thing that happens. Starting out as a member of The Brotherhood of Makuta, Teridax coerced his teammates into betraying Mata Nui, then infected him with a virus. After Mata Nui succumbs to the virus and falls into a coma, causing innumerable amounts of destruction throughout the Cosmos, Teridax plans to erase the memories of an island of Matoran, then play himself up as their Savior. When the Toa, the heroes of the Matoran, try to free them from Teridax, he tries to kill them all before being sealed away. Eventually escaping, Teridax begins a centuries-long war against the Toa, at one point releasing the omnicidal Bohrok, who attempt to wipe out thousands of innocents. Teridax influences the Piraka into finding the Mask of Life, to which The Spirit of Mata Nui is bound, and they commit numerous atrocities while under Teridax's influence. Teridax assists the Toa in finding the Mask, knowing one of them will have to sacrifice themselves to keep The Spirit of Mata Nui alive. Teridax then reveals he played them all, takes control of Mata Nui's body, achieves godhood, then flings Mata Nui into space. Teridax goes on to murder his former allies, wage war against the remaining Toa, and subject any rebels who try to stop him, or minions who anger him, to horrific punishments. Traveling to the planet Mata Nui has been residing on, Teridax's last act is trying to blow it up just to spite him. While Teridax's final destiny was preordained, his villainous actions only worsened his and the universe's fates. Teridax was a monstrous and sadistic sociopath whose god complex cost millions of lives and ruined many more throughout his 100,000-year campaign of evil.
 * Makuta Mutran is a sadistic Mad Scientist who serves the Brotherhood of Makuta for the chance to perform his psychotic experiments unimpeded. Causing trouble even when the Brotherhood was more heroic, Mutran creates Matoran devouring monstrosities and is known to have, in just one instance, unleashed his beasts during the time of a civil war so as to cover up the death and destruction his creations wreak. Once gaining insight into the future and learning Teridax'd plans and the universe-wide destruction it will cause, Mutran doubles his efforts to get into Teridax's good graces and happily joins his revolution against Mata Nui, continuing his horrifying experiments in the process. Once developing the nightmarish Shadow Leeches, parasites that painfully devour all of the good out of their target, Mutran happily obliges Terudax's order to use them on an entire island, and thus rips out the morals of hundreds of Matoran, turning them into the Brotherhood's evil slaves. Wanting nthing more than to torture, experiment, and dissect all around him, what Mutran lacked in power he more than made up for in unbridled scientific sadism.
 * The Shadowed One is the cruel head of the Dark Hunters, a shadowy organization of assassins and bounty hunters willing to do anything for profit. Ruling the Dark Hunters with an iron fist, the Shadowed One punishes minor slip-ups with torture and dismembermet, failure with death, and treachery with far worse than either. The Shadowed One uses the Dark Hunters to carry out countless acts of murder, slavery, and kidnapping, and, though many of the Hunters are just psychotic and greedy, some are forced into service by the Shadowed One when he threatens their lives or the lives of their loved ones. With no loyalty or true care to any but himself, the Shadowed One's Dragon lives a constantly tortued ezistence due to horrifying experiments the Shadowed One performed on him, while the Shadowed One's "closest aly", Ancient, is coldly executed by the Shadowed One to cover up a secret weapon of his own. By the end of the story, the Shadowed One has foregone all form of secrecy and subtlety to instead wage a war against the entire city of Metru Nui and later attempting to harness the power of a lethal virus to blackmail any civilizations he wants with it. The Shadowed One is regarded as the most dangerous person in the universe alongside Makuta Teridax, and he does nothing to dissuade this.
 * Roodaka is a treacherous manipulator who plays any and all potential allies for fools to get what she wants. With her powers of mutation, Roodaka makes a name for herseld in both the Dark Hunters and the Brotherhood of Makuta due to her habit of mutating people into monstrous beasts to cow them into her service. Once becoming the Viceroy to Sidorak, king of the Visorak horde who she eventually betrays and leaves for dead, Roodaka uses her position to aide Teridax in wiping out entire islands of all life and turning any Toa who stand against her into mutated beasts just to mock them. Roodaka's biggest and most wicked plan is to release Teridax from his confinement, fully knowing the countless amounts of death and destruction he will cause, but uncaring as long as it asserts her dominance in the universe. One of the msot self-serving villains in the BIONICLE universe, Roodaka truly cared for nothing and nobody besides herself and her own power.
 * Pridak was once the self-appointed ruler of the "League of Six Kingdoms", a villainous empire headed by himself and 5 other criminals, together known as the "Barraki". As the leader of this League, Pridak organized the ither Barraki to conquer nearly the entire Matoran Universe, slaughtering all those who aren't enslaved, with Pridak's own minions fairing no better, as he orders a battalion massacred simply because 3 of the over 50 soldiers in said battalion took a break. Though severely weakened after being locked away in the underwater prison the Pit, Pridak continues his plans for conquest, as he dismembers fellow Barraki if they question him, sic his pet sharks on Matoran, and forces another to watch as his city is ravaged by Pridak's forces. After escaping the Pit and ditching the other Barraki, Pridak tries to resume his insane plans for conquest, successfully wiping out a small island before being stopped. Pridak was the worst the Barraki had to offer, and gleefully accepted this role in stride.
 * Tuyet, a Toa of Water, is a fanatcial Knight Templar obsessed with imposing her own "order" on the universe. While a nasty being who sadistically murders 3 Matoran to cover up a weapon she found in the "prime" Matoran Universe, it is in the Dark Mirror alternate universe where her evil shines. Having evaded capture for her Matoran serial killing by murdering Toa Lhikan, Tuyet uses the Nui Stone to convince other Toa to join tigether and create the "Toa Empire", a military ruling body that imposes their veesion of peace on the Matoran. Any Toa who stood against Tuyet were summarily brainwashed or executed, with the same fate befalling countless Matoran for the pettiest of infractions. Along with covering the walls of her base with "trophies" ranging from weapons of falen opponents to the opponents themselves, turbed into living statues and decorations, Tuyet treats the Matoran as animals to be subjugated, going so far as to almost wipe out hundreds of them who rebel, only hesitating because it would leave her with less to lord over. With a final plan of conquering all other universes and turning then into totalitarian society she has created in her own, Tuyet was a terrifying example of a Toa's ability to take their "duty" way too far and becone far worse than those they claim to oppose.
 * Annona is one of the few villains to surface only after Teridax's defeat, and handily the worst. An ancient, dream devouring entity, Annona drains entire civilizations of their dreams for empowerment, and the resulting lack of dreams drives the victims insane before they agonizingly die, something Annona drags out as long as possible so as to savour the taste of the dreams. After failing to drive the Great Beings themselvws to madness to assert her dominance, Annona replenishes her strength by draining the Iron Tribe's dreams, leading to the annihilation if the Tribe, and later grants all females of the Skrall species with psionic abilities to watch as they wipe out the male Skralls for nothing but her own entertainment. Once awakening from her slumber, Annona enslaves the female Skralls for failing her, turning them into controlled puppets, then attempts to continue her spree of dream devouring, even attempting to weasel her way out of a fight so as to feed on an entire planet. Treating her victims as nothing but "lunch", Annona was a pure evil monster who stands out as the only pure evil villain the Matoran encounter on Bara Magna.
