"There is only darkness for you, and only death for your people. These ancients are just the beginning. I will command a great and terrible army... and we will sail to a billion worlds. We will sail until every light has been extinguished. You are strong, child. But I am beyond strength. I am the end."

Cartoons have always been home to supervillains whose whole lives seemed to be dedicated to committing evil acts, without any redeeming qualities to speak of other than humor. And then there are some who took it even further. Much further.

  • 3Below: General Val Morando, the exiled leader of the Talyon Phalanx, is an inveterate user of disposable pawns who fancies himself a Galactic Conqueror. In the premiere, Morando seizes the throne by launching a destructive coup on Akiridion-5, oppressing the populace, with their resistance punished with death. Morando manipulates the royals' protector, Varvatos Vex, by having a civilian satellite destroyed to kill Vex's family and hundreds of innocents with them, using it to turn him against the royals and gleefully pledging to make him watch as he kills his new family when Vex realizes he's been played. Throughout the series, Morando attempts to torture one of the heroes' allies into becoming his new general; murders his failed minions and bounty hunters for reasons as petty as delivering him bad news; falsely promises the bigoted Colonel Kubritz a world without aliens, before killing her when she disobeys him; lobs a meteorite at Earth merely to disguise his own arrival upon it; and, after slaughtering his way through swathes of the royals' allies, integrates himself with the core of Gaylen to make himself a virtual god, intending on destroying and reshape the universe to give it the "order" he so craves.
  • Action Man (2000): Dr. X is the mastermind of all the evil in the series, committing all his crimes in the name of evolving humanity into perfection for him to control. X kicks the series by off by kidnapping, torturing, and bodyjacking the young athlete Brandon Caine, using his body to form the Council of Doom and carry out a variety of atrocities against humanity. Seeking to weed out the weak and useless parts of humankind and replace them with a "Neo-Humanity" of his own design, X unleashes lethal plagues, threatens nuclear and winter holocausts, and attempts to copy his mind into every human on the planet to reign supreme. X's supposedly well-intentioned goals are disproven time and time again with his sadism and egomania, before he finally snaps and drops all pretense of improving humanity to instead try to drag an asteroid down to Earth and wipe out all life on the planet—including his own Council of Doom—before creating a new race of humans in his own image.
  • The Adventures of Puss in Boots: The Bloodwolf is an ancient being of fear that existed before time itself begin, once attempted to destroy the entire world before being sealed away by a wizard named Sino in the Netherworld. Upon being released by Uli, the Bloodwolf shows no gratitude and tossed him aside while coldly stating that he'll destroy him and the whole town of San Lorenzo. The Bloodwolf later tortures the whole town with their greatest fear so that he could wait for the Blood Moon where he would reach his full power, so he could continue his quest to bring about the complete destruction of the world.
  • The Adventures of Tintin: R.J. Rastapopoulos is, much like his counterpart from the original comics, Tintin's most ruthless foe, and personal Arch-Enemy. Initially appearing to just be a benign film producer, Rastapopoulos is eventually outed as being the leader of a massive drug smuggling ring that is operating out of Africa and Asia. Anyone who opposes Rastapopoulos is either killed or driven insane by a special poison, and when Tintin begins dismantling his organization, Rastapopoulos tries to have him and his allies, the Wangs, beheaded by the Wangs' own poison-maddened son, Didi. Later, in attempt to rebuild his criminal empire after it was toppled by Tintin, Rastapopoulos draws up plans to steal the wealth of a millionaire named Laszlo Carreidas using a truth serum developed by his new ally, Doctor Krollspell. When he is accidentally injected with the serum, Rastapopoulos inadvertently lets slip that he was going to shoot Krollspell as soon as they finished with Carreidas. When this plan is foiled, Rastapopoulos, under a new identity, starts promising Arab refugees safe passage to America. After the refugees give him all of their valuables, Rastapopoulos has them drowned in the Pacific. When Tintin begins investigating his latest activities, Rastapopoulos tries to get rid of him by planting a bomb on a passenger airplane that Tintin had boarded, and by blowing up one of his own refugee-filled ships when it is taken over by Tintin.
  • Adventure Time: The seemingly sweet land of Ooo has many villains, but while many are either very tragic or not serious, the same cannot be said of this despicable duo:
    • The Lich is an evil, ancient sorcerer and the "last scholar of GOLB", who returns time and time again from seeming destruction focused solely on one thing: the destruction of all life. With his first few attempts to use his well of power to restore his power and bring about the end of Ooo foiled by Billy and later Finn, the Lich possesses Princess Bubblegum to use her body for his purposes. The Lich later murders Billy in retribution for his past defeat, wearing his skin to trick Finn into giving him the Enchiridion so he can enter the Time Room and wish for the extinction of all life across the multiverse. The Lich spitefully murders Prismo and his physical body and tries to use an army of cosmic breakouts to destroy a billion worlds across the universe, turned into a harmless baby named Sweet P afterwards. Even then, a version of the Lich from a parallel reality later manipulated that world's version of Finn to gain access to the multiverse and build up a mountain of broken bodies, even mentally torturing Sweet P for nights on end to try and turn him back into the Lich as his last scheme. Permanently changing the tone of a once-zany show with his presence, the Lich and his endless devotion to the destruction of all life immortalize him as the most horrifying villain in the series.
    • "Preboot" & season 8's "Islands" miniseries: Dr. Gross was formerly a scientist and doctor on the series of islands founded by Minerva Campbell as a refuge for the remnants of humanity, training children to become "Seekers", with no hesitation in brainwashing them and having them brutalize their own friends to prevent any escape from the islands. Dr. Gross eventually turned to twisted experiments on sapient beings, with her recklessness accidentally unleashing a virus that killed off two-thirds of all humanity on the islands—to her complete apathy. Escaping the islands, Gross continued her experiments, scheming to return to the islands and forcibly augment all humanity into cybernetic abominations like herself, even trying to cut apart Finn and his friends to use as raw material. An unfeeling scientist with zero empathy, Dr. Gross proves that, sometimes, Humans Are the Real Monsters.
  • Adventures of the Galaxy Rangers: The Queen of the Crown is an evil sorceress who starts off by ambushing Kirwin, and putting a heavy bounty on humans for every two-bit thug in the galaxy. She is mashing the humans down to power Slaver Lords, artificial creatures through which she can see, hear, and administer her Empire; this is not only an exceedingly painful process, but leaves the victim fully awake and aware of what's happened. The Queen also slaughtered millions on the planet of Tortuna, leaving a few domed cities behind in a lot of wasteland. She was hunting humans because the last race she used to power Slaver Lords has been hunted to near-extinction and she needed replacements. If that wasn't bad enough, she enslaves an entire planet, making the inhabitants work in concentration camp conditions to build a massive hyperspace cannon she uses to blow a chunk out of Earth's moon, threatening to do worse to Earth unless they gave her 5,000 humans in tribute. On a personal level, she uses the only psychocrystal she's made from a human—Zach's wife—to commit Mind Rape nightly on both of them.
  • Alfred J. Kwak's two-parter "The Strange Bottle" and "Flying Carpet": The Evil Spirit Of Darkness is an evil genie who terrorized the land long ago for fun, causing droughts, floods, storms, plagues, and fires, destroying cities and killing many people. After The Almighty One sealed the spirit inside a bottle, the spirit vowed that when it was freed, it would kill whoever freed it to spite the god who punished it previously, before returning to its homeland to terrorize the people once more. When Dolf and Alfred free the spirit, it tries to eat Alfred despite the fact that he is a child.
  • Alienators: Evolution Continues:
    • General Granger is a high-ranking general with ambitions of establishing a New World Order to control humanity, believing that humanity is prone to violence and self-destruction without the guidance of a strong leader. To achieve this goal, Granger allies with SCOPES and the Genus, supplying the Genus with missiles to infect the entire planet and breaking SCOPES out when the latter is captured by the Alienators. During the series finale, Granger plans to launch more missiles to spread the Genus across the planet and planning to give the Eastern Hemisphere to SCOPES so he can rule over what's left. When the Alienators foil project Alpha-Omega, Granger tries to restart the project through using the satellite defense system to launch a nuclear strike on the moon so the Genus cells there could be spread across Earth and successfully acquires most of the launch code. During the final battle, when Ira reveals to Granger that SCOPES has no intention of keeping his end of the bargain, Granger refuses to listen and continues to believe that SCOPES was under his control.
    • SCOPES is the sapient presence leading the Genus invasion. Believing that the Genus were superior to humanity and seeing human empathy as a weakness, SCOPES seeks to spread the Genus all over the planet and destroy humanity. To this end, SCOPES attempts many times to kill the Alienators while taking every opportunity to spread Genus cells across Earth such as trying to use the fallout from a nuclear submarine as well as missiles supplied by General Granger to ensure the evolution of the Genus goes unimpeded. In the finale, SCOPES works with Granger to nuke the moon and spread the Genus cells across Earth, with SCOPES himself planning to spread the moon debris across the universe. When confronted by Ira in the series finale, SCOPES reveals that he has no intention of dividing the world between himself and Granger. Instead, he plans to change the Earth's atmosphere to be inhospitable to humans so that only the Genus could reign supreme.
  • Angel Wars: Morg was once a heroic angel, but betrayed his kind to ally with the satanic Dragon for power. Failing to kill his best friend Michael and deliver a powerful Foundation Stone to the Dragon, Morg was imprisoned for ages before escaping by nearly driving a man insane and feasting on his negative energy. Morg immediately murders his former partner Graven upon escape and steals back the Foundation Stone, using it to nearly wipe out a moon colony of humans and following it up by trying to destroy all life on Earth. After merging with the Foundation Stone, Morg begins devouring everything and everyone in sight, primarily his own minions, and then reveals his goal to ensure that nothing in the universe is "higher" than himself by devouring all life in existence.
  • Animalia: Wooster Q. Weasel—better known as the Creeper—is the former king of Animalia, and brings an unprecedented darkness to a series that had otherwise been very lighthearted. Having become drunk on his own power during his tenure as king, and exiled for the safety of Animalia as a whole, the Creeper resolves to take back the power of the Core regardless of the consequences to Animalia. A refined manipulator, the Creeper attempts to start a war in Animalia through Tyrannicus, and after this fails, moves on to tricking his old friend King Livingstone and his young friend by pretending to undergo an epiphany, only to backstab the two and try and have them blown away to their deaths into the Winds of No Return purely out of spite. The series finale sees the Creeper at his nastiest: Upon taking the power of the Core and resuming control of Animalia, the Creeper brainwashes and captures all resistance and ultimately strives to use the knowledge contained within the Corespore to travel to and subject other worlds entirely—at the consequence of killing off everyone in Animalia.
  • The Animals of Farthing Wood's season 2: The blue fox Scarface is a ruthless bully who begins killing the Farthing animals when he can get away with it. After having a litter of children with his mate, Lady Blue, Scarface becomes incensed by his rival Fox's children and murders Fox's young daughter Dreamer. When he has an excuse, Scarface rallies his other foxes and kills one of the Farthing rabbits, hunting the Farthing animals down and intending to massacre them one and all. When defeated by Fox, he returns to kill another of the rabbits, showing his lack of honor and refusal to ever stop. Even his son Ranger admits upon attempting to broker peace that his father would murder him should he know of the talks. Vicious, cruel and without any remorse or care for others, Scarface embodies the sheer savagery of the wild, even in a place of peace such as White Deer Park.
  • Archie's Weird Mysteries:
    • "Mega-Mall of Horrors": Calvin Gianni Avericci was an insatiably greedy shopaholic who made a Deal with the Devil, getting all that he could ever want in exchange for becoming a demonic servant of the Underworld, charged with providing it with a steady stream of young, innocent souls. Traveling from town to town, Avericci sets "Mallhalla" up overnight, lures teenagers into it using hypnotic music, and gives them credit cards that they can use in the mall's various stores, which are all stocked with whatever their hearts desire. Once a card's credit limit is reached, Avericci has its owner "pay up" by turning them into an immobile—yet fully aware—mannequin, which he places on display in Mallhalla for days or even weeks before sending it to Hell. Avericci's music lures all of the young people away from local businesses, causing them to go under, and erases everyone's memories of the abducted teenagers, making it seem like they never even existed. Within weeks of arriving in Riverdale, Avericci manages to turn every one of its teenagers into mannequins, except for Jughead Jones, who he decides to simply kill when Jughead proves able to resist the temptations offered by Mallhalla.

Eventually escaping back to present day Riverdale, Vinnie decides to simply destroy the town and kill everyone in it using a time-displaced Tyrannosaurus rex. When the beast corners Archie, Vinnie taunts the teen by describing how happy it makes him that Archie's last thoughts before dying will be of how he failed to prevent his family, friends and beloved Riverdale from meeting the same grisly fate.
  • Argai: The Prophecy: Dark Queen Orial is a serpentine sorceress whose ultimate goal is to one day reign in Hell as the bride of Lucifer. Having made a Deal with the Devil for eternal life, Orial maintains her youth by regularly placing young maidens in magical comas, with one of her victims being Angele, the fiancée of Prince Argaï. Originally a marauding medieval warlord, Orial eventually conquered the world in a bloody campaign that killed a tenth of the population of the Earth, which she then turned into a dystopic Police State in which anyone who steps out of line is either executed or condemned to a Hellhole Prison. Orial regularly disposes of her own allies at the slightest provocation, and when she learns that Argaï is destined to slay her, she resorts to increasingly extreme attempts at eliminating him and his allies, like burning entire villages, leveling a city block, and razing all of Chinatown. In the end, when she realizes that she has been beaten with no way out, Orial spitefully tries to blow up the Earth.
  • Avatar Universe:
    • Avatar: The Last Airbender: Fire Lord Ozai is a genocidal, child-abusing fascist dictator who has dedicated weeks at a time and large portions of his national army to hunting down and killing a twelve-year-old and his friends. He forced Ursa into marrying him, and tried to kill her old lover out of spite. He obtained the throne when he manipulated Ursa into murdering his father to usurp the throne from his grieving older brother Iroh. He then thanked her with banishment from the Fire Nation and threatened to hunt them down and kill the children if she took them with her. He abused his son Zuko out of spite when Ursa claimed that Zuko was not his son even though he knew it was a lie, burned his face for speaking out of turn, and tried to shoot him with lightning when he decides to join Aang. He manipulated his loyal daughter Azula into becoming his perfect little villain to the point where she snaps from the pressure, only to later discard her to a completely meaningless position. Finally, his reaction to news of rebellions in the Earth Kingdom is to try to incinerate the continent. Even after his downfall he still tries to manipulate his son Zuko into being a tyrant like himself.
    • The Legend of Korra: Unalaq is Korra's Evil Uncle, the leader of the Northern Water Tribe, and one of the primary villains of Book 2. Years ago, Unalaq, jealous of his older brother, Tonraq, had him exiled from his home tribe after framing him as responsible for the destruction the Dark Spirits inflicted on their tribe. Later trying to have Avatar Korra, a child at the time, kidnapped, Unalaq abandoned his partners to their fates when the plan failed. When the Dark Spirits return, Unalaq takes control of the Southern Water Tribe from Tonraq and has anyone who may oppose him disposed of, triggering a war between the water tribes. Later attempting to open a spirit portal, Unalaq tries to leave his son to die when he is injured, and, realizing only the Avatar can open the portals, threatens to destroy the soul of Jinora, a little girl, to force Korra to assist him, then tries to condemn Jinora to the Fog of Lost Souls and to murder Korra even after she opened the portal. Revealing his true colors, Unalaq assaults the Southern Water Tribe; beats down Tonraq, sparing his life solely so he can see Unalaq win; then frees Vaatu, the spirit of darkness and chaos, with whom he has been partnered with the entire season, fuses with him into a Dark Avatar, and tears the spirit of light and order, Raava, out of Korra and attempts to obliterate her. Unalaq then attacks Republic City and announces his plans to rule over humanity after destroying all world order. A sociopath with a god complex, Unalaq stands out as the most monstrous villain in this series.
  • Babar: The unnamed hunter, the Big Bad of the first five episodes, focusing on Babar's childhood, is the darkest and cruelest villain in this mostly lighthearted series. Initially seeming to be a simple Evil Poacher, who relentlessly hunts a herd of elephants, one of his successful kills was Babar's own mother. The hunter continues this, even when he witnesses multiple instances of the animals being sapient, eventually calling in a bigger team of poachers to wage war on the animals. His only apparent motivations are greed and wounded pride over being beaten by a young Babar. This eventually comes to a head when he has the rhino village destroyed, and sets fire to the jungle to wipe out all its inhabitants. When the fire is beaten back, the hunter dies defiantly screaming how he'll stop at nothing to destroy the animals.
  • Ben 10 franchise:
    • Vilgax, the Overarching Villain of the entire franchise and by far Ben Tennyson's most personal enemy, is a psychopathic galactic warlord. After his evil caused him to be banished from his homeworld, Vilgax went on to assault and conquer numerous planets across the cosmos, outright annihilating the entire planet of Petropia and its billions of inhabitants to make an example of those who resist him. After discovering the existence of the Omnitrix, Vilgax becomes obsessed with possessing the gadget to modify it for his own gain, and spends much of the first series sending wave after wave of his forces to Earth solely to kill Ben Tennyson, a 10-year-old-boy, and steal the watch from him, later trying to viciously saw the boy's arm off and blow up the entire Earth for the trouble it has caused him. In Alien Force, Vilgax builds up his image as a law-abiding citizen by "legally" conquering 10 planets, though ultimately ditches this persona and tries to use the Omnitrix to lead a full-scale war against all who would stand against him. In Ultimate Alien, Vilgax becomes the herald for Diagon before betraying and killing his master and stealing his power, hoping to use it to mind control all life in the universe. In the final series, Omniverse, Vilgax, though at first seeming to have decayed in his evil, pulls out perhaps the most wicked scheme in the entire franchise, using a Chronosapien Time Bomb to wipe out all dimensions and timelines, his own included, to leave only a single, more submissive universe for him to conquer and rule. Vilgax was a purely evil madman who would kill first billions, then insurmountable trillions, just to satisfy his raging desire to be the most powerful being in the universe, and stands out as the most iconic villain in Ben 10 for this very reason.
    • Ultimate Alien: Aggregor is an Osmonian warlord who is wantonly murderous in his quest to achieve omnipotence. Aggregor killed aliens by absorbing their energy and matter to gain their powers. Generally this caused his victims to turn into desiccated husks, but for his plans to become powerful enough to reassemble the Map of Infinity, he turned five aliens into energy and absorbed them into himself. Aggregor killed Magister Prior Gilhil by stabbing him in the back, killed two other Plumbers by sucking them into space, and absorbed the life and powers of a pacifistic alien just because he could. His two most vile crimes, however, were when he nearly destroyed an entire inhabited world by stealing a component from the device that kept the planet from breaking apart, and when he tried to kill and absorb a baby alien capable of Reality Warping to complete his ascension into godhood.
    • Omniverse's season 8: Maltruant is a rogue Chronosapien bent on ruling all of time and existence. He masterminded the original Time War in his first bid for universal control, but was defeated and his body separated across time by Professor Paradox. Seeking to restart the Time War and win, He hired Dr. Psychobos to help repair himself. After Subdora and Exo-Skull complete repairing his body, Maltruant turned on Dr. Psychobos, easily defeated Ben Prime and Ben 23, and left both for dead in Mad Ben's dimension with his minions to restart the Time War. Once he travels to the time period of Ben 10,000 to steal the Anihilaarg and the Dwarf Star so he can create a more deadly weapon, Maltruant traveled back to the very beginning of the universe and snuck aboard the Contemelia's ship, where he switched their Anihilaarg with his own in order to recreate the universe in his image.
  • Blake and Mortimer: Colonel Olrik is even more fiendish than in the comics. A mercenary willing to work for the highest bidder, Olrik is first introduced working as a military adviser for an empire and leads bombing runs against several major cities, devastating them and killing thousands in the process. Olrik wants to steal Professor Mortimer's new invention the Swordfish plane, betray the Empire and rule the world himself. After that scheme is foiled, Olrik returns, leads a military coup that turns a democratic country into a dictatorship and joins forces with a rogue general in Atlantis, trying to encourage a military coup there as well that would leave hundreds dead, just to plunder Atlantis's resources. Olrik later shows up and commissions a Mad Scientist to build a machine that controls the weather. Olrik uses this machine to cause disasters across Europe, until he unveils his master plan to blanket Western Europe in a toxic fog, killing everyone, so that a foreign power can successfully invade. Much later Olrik is seemingly killed after trying to using alchemy to gain immortality, but he is merely banished to an alternate world, where he takes over and rules as a dictator. Wanting revenge for being banished from the Earth, Olrik plans to use a powerful moon medallion in a ritual that would destroy the Earth.

    • "The Towers of Crystal": Prince Zelgung, angered over losing the throne of Mu to his sister Taima, proceeds to destroy his own civilization by launching a nuke on the city, causing the population to die from the blast or painfully succumb from the radiation. Despite himself and his loyalists getting caught by those radiations, Zelgung displays no remorse and repeatedly attempts to slaughter the survivors lead by Taima. When they leave the continent on a time traveling ship, he tries to launch a missile at it.
    • "The Angels of Ananke": Emperor Hang and his chancellor Golo are tyrannical leaders of the city of angels, with any man who trespasses on their territory ending up enslaved. When Bob defeats the champion Korto in combat, Hang forces the hero to train his army, threatening his friends Bill and Sophia if he refuses. Golo at one point threatens a group of slaves who tries to take a break, while Hang tries to have Korto executed for his failure and gets rid of a servant for spilling wine. It's finally revealed that Hang and Golo regularly abduct humans and angels and hook them in pods that drain their mental energy to power the anti-gravity field. When Bob and Korto discover their scheme, they put the latter in the battery and attempt to have the former publicly executed.
  • Brats of the Lost Nebula: The Hosts are a pair of ancient Energy Beings who, to maintain their power and immortality, assembled the Shock, a mechanical army which they used to enslave an entity called the Eye. The Eye is Forced to Watch as the Shock destroys inhabited worlds, with its sorrow over the genocides being converted into a special energy that invigorates the Hosts. The Hosts have razed thousands of planets and wiped out an untold number of species like the Artisans, a benevolent race whose only remaining member they tortured and brainwashed into becoming their sadistic second-in-command, High Commander Hextar Vigar. Even though Vigar serves them admirably, obliterating numerous planets at their beck and call, the Hosts treat him with nothing but contempt, and take perverse pride in the fact that they twisted a once good man into a monster who they believe is incapable of loving anything, even himself or the Hosts.
  • Cadillacs and Dinosaurs:
    • Hammer Terhune, who works for Governor Scharnhorst, one of the leaders of the City in the Sea—New York City After the End—tries to discredit Jack Tenrec's philosophy of promoting a balance between humans and nature. To do this, Hammer uses a sonic transmitter to torment a T-Rex and have it attack nearby settlements. Hammer also tries to discredit Tenrec by trying to cause a bunch of Triceratops to stampede and kill people in a mining town. Unhappy with taking orders from Scharnhorst, Hammer hijacks a killer satellite and plans to use it to destroy the City in the Sea, so that he can take over. Later Hammer discovers a boy who can control dinosaurs and wants to use him in his poaching business. To test the boy's skills, Hammer throws him a pit with a hungry raptor and sees if he can control it. In his final appearance, Hammer uses some stolen dynamite to try to flush out some dinosaurs, but this causes a wildfire instead. The wildfire is heading towards some gas wells Scharnhorst recently constructed and if the fire reaches the wells, it will cause an explosion that will devastate the jungle, resulting in mass starvation for the City in the Sea. Scharnhorst orders Hammer to work with Tenrec to fix this problem, by helping Tenrec use nitroglycerin to create a barrier between the fire and the wells. However, Hammer intents to kill Tenrec instead and steal the nitroglycerin for himself, not caring that his actions have endangered millions of lives.
    • "Duel": Sean Russel is Jack Tenrac's old friend and rival. Russel sabotages Tenrac's car and steals a helicopter engine from him. He uses his new helicopter to go to the home of the Grith, a race of peaceful sapient lizard creatures who communicate through telepathy, and steals the life stone, a gem they need to survive. Russel uses the stone to summon several dinosaurs to a valley. Russel captures Tenrac and says he invited Hammer Terhune and his brothers to come and slaughter both the dinosaurs and the Grith, planning to sell their meat and bones on the black market. Tenrac lectures Russel about selling out the Grith to make a profit and Russel seems to briefly feel guilty over it, but quickly decides he cares far more about money then his old beliefs and continues with his genocidal scheme.
  • Captain Planet and the Planeteers has these two Knights of Cerebus, who are proudly motivated more by sadistic enjoyment than mere greed:
    • Zarm, the Spirit of War and Destruction, is arguably the strongest and most deadly adversary of Gaia and the Planeteers. A former Spirit of the Earth exiled by Gaia, Zarm dedicates himself to bringing ruin and destruction in all forms to Gaia and all she protects out of vengeful spite, having consumed at least one planet to the tides of destruction and constantly attempting to do the same to Earth. Zarm attempts to initiate all-out nuclear war on Earth; painfully reverts Gaia to a withered old lady incapable of stopping the Earth from dying and taking over the Earth for a ten-year-period of time where the Earth has become desiccated and ruined; coins a strategy he calls "Scorched Earth" by convincing world leaders to obliterate their own land and people—and claims to have been "a part of every important tyrant in history"—and nearly dooms the Planeteers' efforts to stop an alternate timeline where the Eco-Villains' descendants rule the planet by smugly ordering a young girl Ma-Ti saves murdered. A sadist drunk on his own capacity for destruction, Zarm is one of the single greatest sources of human misery within the show.
    • The appropriately-named Verminous Skumm is a humanoid rat-man who, despite being far less powerful than Zarm, manages to be just as evil. Taking a sick pleasure in the polluted and festering, Skumm's schemes vary from willingly endangering and trying to destroy entire cities, and include deliberately trying to destroy an entire city with a cloud of acid rain and flooding Venice with oversized, carnivorous rats; peddling mind-altering drugs and even murdering Linka's cousin Boris through them; attempting to bait two sides of the Arab–Israeli Conflict into using a nuclear bomb in Jerusalem Mount, as well as bringing nukes into The Troubles and apartheid South Africa; and attempting to flood the entire world with his "Rat Rot" chemical to turn everyone into his mutated rat slaves. Skumm's end goal is to destroy the civilized world and enslave what remains to his mutated Rat Men followers to rule over them all as a king. Happily admitting " I'm ignorance; I'm fear; I'm hate" and taking delight in everything from ruining the life of a single person—a teenager with AIDS—for giggles, to the attempted annihilation of millions of lives, Skumm stands out as the darkest of the recurring Eco-Villains due to his propensity to target people rather than the environment.
  • Captain Simian and the Space Monkeys: Lord Nebula is a half-human half-black hole creature who seeks the destruction of the entire universe so he can rebuild it in his own image. Nebula orders his henchman Rhesus-2 to acquire the anti-force, but ends up tricked and reduced to a humanoid form. During the series, Nebula frequently threatens to kill Rhesus-2 when he fails him and shows how awful he truly is when it is revealed that when Rhesus-1 failed him too many times, Nebula violently killed and disposed of him. To complete his plan, Nebula captures Simian's crew, but since Simian was able to escape, Nebula orders Rhesus-2 to torture them until they give up Simian's location. When Simian does return and promises to give up the part he needs, Nebula reveals to Rhesus-2 that he lied to him and was never planning on giving him a Pocket Universe to rule over.
  • Chuck Norris: Karate Kommandos: The Claw is the leader of VULTURE, a cabinet of terrorists willing to wreak vast destruction under the Claw's firm eye in their goal of world domination. The Claw, throughout the series, hijacks an undersea lab to use its powers to try and wipe out coastal cities; tries to seize a NATO memory core to disable their defenses; coldly orders Norris's young friend Too Much murdered; attempts to seize a powerful laser robot to use it to attack and devastate Tokyo and orders a train full of people transporting it spitefully destroyed; and steals a shuttle to try and extort billions of dollars out of all the world's major powers lest he use a Kill Sat to obliterate all of the capital cities of each powerful country around the world. Throughout the series, the Claw regularly tortures and murders his own minions with aplomb and is happy to claim as many civilian lives as it takes to further his own nefarious agenda.
  • Class of the Titans: The Titan Cronus, when released from his prison in Tartarus—where he was imprisoned for being an evil tyrant and for trying to kill his kids—wastes no time in seeking to resume his dominance over the world and all in it. With nothing but hatred for his children and the other Gods, Cronus is utterly brutal and merciless in his tactics, which include torturing and trying to kill his own children while throwing the world into chaos and disarray.

Hanek is behind several of Intracom's malevolent affairs, such as burning down vast sections of the rainforest to biting and turning several innocent people into vampoid slaves. Hanek demonstrates his vileness by attempting to have the Tree of Light destroyed, which would in the process completely wipe out the Banshee Sisterhood, and turns an innocent woman into his vampoid concubine to hurt one of the Alliance's agents.

Stationed in Earth back in 1946 to divide the alien races and allow the Shadoen to invade and conquer the planet, Wraith butchers the real James Rinaker and assumes his identity, bombing a Conduit safehouse and killing several innocent aliens to pin the blame on the Alliance's co-leader Walter Logan before trapping Walter himself in eternal stasis to take over the Alliance. As Rinaker, Wraith traps hundreds of innocent aliens in the Alliance's prison and has little compunction in arranging torture, bombings, and heavily destructive missions with little care as to who or what gets caught in the way, whilst simultaneously sabotaging several of the Alliance's missions and endangering several more lives. After his initial attempt to pin his crimes on Nick Logan, Wraith personally murders Ms. Smith-Heisen once she gets too close to the truth without an ounce of emotion on his face before discarding his disguise, rigging the entire Alliance bunker to explode and take out half of New Mexico, and savagely murdering Trueblood with his own claws. Rejoining the Shadoen fleet and still unsatisfied with how he's being treated, Wraith tricks the Shadoen high command into being nuked by the human army and spearheads the invasion himself, ultimately resolving to blow up the moon and kill off most of humanity to conquer what remains, with his only stated regret being the loss of "breeding stock" this will incur. A traitorous, manipulative sociopath even by the standards of the world-destroying Shadoen, Wraith is the most dangerous—and vile—alien to grace the series.
  • Samurai Jack (season 5): While Aku himself is Made of Evil, this duo from the final season proves that, sometimes, Humans Are the Real Monsters:
    • The High Priestess is the leader of the Cult of Aku, and a zealot dedicated solely to appeasing the dark god she worships by any means necessary. Drinking Aku's essence and giving birth to septuplets with Aku's dark energy within them, the High Priestess dubs them the Daughters of Aku and proceeds to horribly condition them into unfeeling weapons whose sole purpose is to kill Samurai Jack. The High Priestess systematically abuses them for years on end, searing their flesh with hot coals while they're still young and putting them through brutal, life-or-death training routines where every slight distraction means torture and beatings—sometimes simply for things as minor as looking outside. Having the Daughters graduate by having them massacre her own devoted followers, the High Priestess sends the Daughters into the world to kill Jack and callously brushes off the deaths of most of them at Jack's hand, furiously attempting to kill Ashi, her only surviving daughter, with her own hands after she finally turns on the High Priestess. An unfeeling fanatic able to rival her own dark god in evil, the High Priestess justifies her cruelty simply by stating Jack must die at any cost—regardless if that cost is her own flesh and blood.
    • "XCVI": The Dominator is a sadistic Torture Technician seemingly motivated purely by a desire to hurt people. Slaughtering a village of innocents and abducting all of their children, the Dominator painfully transforms all of the children into psychotic killing machines to be used as weapons, and tests them out on Jack and Ashi once they try to retrieve the children, with complete knowledge Jack's refusal to hurt innocents makes him easy prey. The Dominator brutally tortures Ashi upon capturing her with clear lascivious intent, gloating that children are easily manipulated tools—and that Jack's refusal to hurt them only makes him a "righteous fool".
  • Sandra the Fairy Tale Detective: Bluebeard is even more monstrous than his original counterpart.

After Horde is resurrected after an encounter with Dragon, he manipulates the corrupt Dr. Reginald into using his new laser to destroy the ozone layer, which will cause a heat-themed apocalypse that'll allow Horde to walk amongst the earth and take it over, later betraying Reginald when his plan's almost complete. Returning one final time, Horde possesses the minds of the Vicious Circle to get closer to the world's leaders, hoping to plant his leeches onto them and be able to control the world through them.
    • "Loathing", "She-Fiend", "Endgame": The Fiend is a demonic entity who gleefully feeds on hatred. Regularly possessing people who have a strong hatred for somebody, the Fiend regularly enacts his hosts' hurtful desires for fun. Possessing a hateful self-help guru about to give a seminar on a yacht, the Fiend tries to have everybody on the yacht killed by steering the ship into an island. Later taking control over She-Dragon to feed off her hate for Overlord, the Fiend taunts Dragon over the fact that he's endangering her. In his final appearance, the Fiend acquires a magical orb, using it to absorb the agonized souls of hateful people to increase his strength, utilizing its power to open up a portal and suck up every hateful soul from across the entire universe.
  • Scooby-Doo! Mystery Incorporated: The Nibiru Entity is a member of a normally benevolent inter-dimensional alien race called the Anunnaki, which considers him the most evil member of their entire species. He's spent untold centuries corrupting and manipulating everyone around him, especially the team pets of mystery solving teams, by perverting his species' ability to use animals as mediums to communicate, all working towards freeing him from his prison. In the process he's ruined and ended countless lives through his pawns, including Professor Pericles, who the Entity turned into a murderous psychopath. When he's finally released in the finale, he proceeds to gleefully eat his loyal minions alive, along with Mr. E.

When Mystery Inc. finally kill him, erasing him from time in the process, we see what Crystal Cove would've been like without his influence: a normal town with everyone living good, happy lives, showing just how much pain and misery he was truly responsible for.
  • The Secret Saturdays:
    • Vincent Vladislav ("V.V.") Argost is the Arch-Enemy of the Saturday family and the eerie host of "Weird World" whose lust for power is only matched by his charismatic flair for the theatrical. A Himalayan Yeti who years ago spent his days hunting and attacking travelers in the mountains, taking trophies from his kills and claiming the lives of Drew and Doyle's parents during this time, Argost eventually disguised himself as a human so as to better hunt down the legend of Kur.

Eventually draining the power of Kur from Zak Saturday's doppelganger Zak Monday at the cost of the boy's life, Argost hoped to first conquer, then kill, all of humanity, and nearly murdered Zak Saturday in the exact same way as Monday in an attempt to achieve his goal of subjugation and extermination of all humankind as his grandest "show" yet performed.

  • Shadow Raiders: The Beast Generals, the malevolent servitors of the world-devouring Beast Planet who help their master The Beast scourge entire solar systems and destroy all worlds within them, each qualify in their own right:
    • Lamprey is a master of deceit and subterfuge who weakens worlds from the inside out through complex gambits, occasionally pausing to murder people who cross her path for little other reason than to amuse herself. Lamprey introduces herself tricking Emperor Femur into installing a device meant to drain all the life from Planet Bone. After this, Lamprey possesses Tekla and tries to use her to destroy the Alliance from the inside out, contenting herself with subjecting her to horrific Mind Rape of her planet's destruction and trying to slowly kill her from the inside once this fails. After this fails, Lamprey murders a resident of Planet Fire and pins it on Jade's hands, intending for her to be horribly executed by being dipped into a fall of lava. Lamprey's final crimes in the series stem purely from petty spite: Seeking revenge against Tekla, Lamprey has her Beast drones attack a bar with the intent to kill everyone inside, personally disintegrates Captain Blaze once he gets in her way, and furiously attempts to kill everyone who stands between her and Tekla before her own demise.

  • Sherlock Holmes in the 22nd Century:
    • Dr. Martin Fenwick is Professor Moriarty's right hand man. Assisting Moriarty in his crimes, Fenwick would commit many crimes, but his worst crime is creating a black market organ trafficking ring by tricking homeless citizens into giving him their DNA. He would then clone organs for back-alley transplants that would inevitably fail without warning, and attempt to freeze Holmes and Watson to death when they uncover his scheme.

A sadist, Cyanure laughed at Spirou and Fantasio's cries of pain when she uses speakers at maximum volume against them, and laughed at a tied-up mini Fantasio when a toy train was about to run over him. In an attempt to kill all humans by mass-producing herself into an army, she kidnaps Professor Sushiyaka to record his paralyzing scream. When he refuses, Cyanure attempts to kidnap her nephew, and when capturing Fantasio instead, she dismantles and set aflame one of her own clones in front of Sushiyaka and threatens to do so to Fantasio if he doesn't record the scream.

When the Mardan, one of the Tlak'kahns' Slave Races, help him capture the Stargate crew, Da'kyll destroys the team's cure for a plague that the Mardan are suffering from while noting that if the Mardan manage to survive the sickness on their own, they will have proven worthy enough to be used as Cannon Fodder. Da'kyll threatens soldiers who fail him with torture, murders his professional rivals, and frequently flouts the authority of the Nax'kan Council, who he intends to overthrow using the knowledge and power of the Ancients.

Upon learning that a fellow centurion was a Christian, he tried to have him killed for treachery. He later set fire to homes of children with them still inside, all because they didn't submit to his emotional manipulation of them.

Later attempting to turn the Swat Kats into ground meat while using their jet to frame them for opening fire on civilians and blowing up entire buildings, Dark Kat follows this up by convincing Razer he severely wounded innocents to throw him off his game while Dark Kat uses a robotic arachnid to attack and hopefully tear Megakat City to shreds. In his arguably worst outing, Dark Kat makes an alliance with Dr. Viper, using him to rebuild the Metallikats then install chips in them that allow Dark Kat to torture them at his leisure. Using the Metallikats and Viper, Dark Kat lures the Swat Kats, Feral, and assistant mayor Callie Briggs into a trap to kill them all, ordering the Metallikats to kill Viper when he outlives his usefulness, and ultimately attempts to blow up the entire base as a last ditch effort to kill the Swat Kats, their friends, and all of Dark Kat's own allies in one fell swoop.

When two children who were prophesied to bring about her downfall are born, the Empress orders them killed, has their doctor imprisoned and tortured, and turns their fathers into inanimate—but still awarestatues, because death would be "too easy", as a punishment for the "defiant act" of bringing her would-be usurpers into the world. After learning that the children were secretly smuggled to France, the Empress gives her eunuchs free reign to destroy anything that gets in their way in their mission to slay the twins. When the twins make it to China, the Empress deploys her armies against them, and allows the soldiers to raze villages and summarily execute people in an attempt to flush the children and their allies out. The Empress regularly threatened her servants with death and mutilation, had planned on murdering her Evil Sorcerer on the unfounded suspicion that he was disloyal, and foregoes executing her incompetent head eunuch in favor of demoting him, because the eunuch spending the rest of his life haunted by his disgrace is a far crueler and more amusing punishment than death.

Taking Rusty on dangerous adventures since he was three years old, Jonas allowed him to be trapped, tortured and put in harm's way, to allow himself the excitement of "rescuing" Rusty as the hero. When working on scientific inventions, Jonas frequently grew bored of his works with dire consequences, in one instance leaving a group of orphans to suffer drug-induced nightmares after an A.I. he created ran rampant, much to Jonas's apathy. His own team meaning nothing to him, Jonas viewed his bodyguard as property, taking him from his "best friend" Blue Morpho as "payment", and turned another into a violent Blood Knight by forcing him to use dangerous drugs. Ruining Morpho's life, Jonas coerces the happily married man into an orgy, then blackmails Morpho with the knowledge and forces him to do his dirty work, and later resurrects Morpho into a cyborg slave, which earned the disgust of his team.
