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.
The Queen of the Crowns from Adventures of the Galaxy Rangers. Her Majesty starts off by ambushing Kirwin, and putting a heavy bounty on humans to every two-bit thug in the galaxy. We find out why - she's mashing the humans down for Life Energy to power constructs through which she can see, hear, and administer her Empire. It's not only an exceedingly painful process, but the poor bastard is fully awake and aware of what's happened. We also see that she slaughtered millions on the planet of Tortuna, leaving a few, domed cities behind in a lot of wasteland. She also was hunting humans because the last race she used to power Slaverlords 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 5000 humans in tribute. On a personal level, she uses the only psychocrystal she's made from a human (Zach'swife) to commit Mind Rape nightly on both of them. Her voice actress in the American version unfortunately sounds like a cross of Ming the Merciless and Maleneficent. The German actress comes across as far more menacing.
From Animalia we have the Creeper; before he arrived, all characters in the show had at least once displayed a softer side, and the worst you could get was greedy yet harmless tiger who beside having some jerk moments wasn't really evil. The Creeper, on the other hand, has no redeeming qualities, and is actually willingly to damage the Code and Animalia for his personal ambitions. His schemes included trying to start a war on Animalia, kidnap a child, and trick the protagonist and Livingstone in falling to their death when Livingstone offered to forgive him for his fault. He steals precious possessions from everybody just because he enjoys doing so. And as if it wasn't enough, he is also an Omnicidal Maniac wannabe...
General Mandible of Antz is a megalomaniac ant soldier who views worker ants as inferior vermin and soldiers as superior. He manipulates the Queen into rejecting peace negotiations with a hostile colony of Termites and sends all the soldiers loyal to her on a suicide mission to attack the Termites and secure his power. Both sides are completely destroyed in the fight except for a single ant named Z, which irritates him to no end. He engineers a new dig for the miners so they will hit a water source that will drown every ant in the colony including the Queen, except for his small faction of army loyalists who will be blindy obedient to him. He tortures Z's best friend Weaver to find Princess Bala after Z took her away, threatens to kill Weaver's girlfriend if he doesn't comply, then orders Z killed seconds after he promised not to do so and arranges Weaver's death as well. To start his new ideal colony he plans to force Princess Bala to marry him after he has killed her mother and everyone else.
Fire Lord Ozai from Avatar The Last Airbender 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 physically abused his son Zuko by burning his face for speaking out of turn, and tried to shot 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 discard her to a completely meaningless position. Finally, his reaction to news of rebellions in the Earth Kingdom is to try to incinerate the entire continent. He doesn't regret any of those moments and feels no remorse for the consequences.
The Avengers: Earth's Mightiest Heroes brings us the Red Skull, who as usual, embraces this trope. The leader of HYDRA in World War 2, the Skull kidnapped mystical creatures to use them to kill the Allies. When the Nazis lost, the Skull opted to kidnap Captain America's teen sidekick Bucky Barnes and torture and brainwash him into the amnesiac assassin the Winter Soldier. In modern times, the Skull continues his dreams of conquest and hatred of Captain America by unleashing a chemical compound to kill the heroes and civilians. The chemical has been engineered to cause slow and painful death by making the victim's face turn into a grotesque parody of the Skull's own.
The Joker from The Batman. Once a man who wanted to make people laugh, he fell into a vat of chemicals and became an insane, murderous Monster Clown and Batman's Arch-Enemy. Devoid of any empathy, Joker commits crimes he views as "jokes" at the expense of Gotham. Terrible things he's done include poisoning people with his deadly laughing gas; putting people in various death traps; torturing Detective Ethan Bennett for hours and causing Bennett's mutation into Clayface; impersonating Batman and gassing people for minor crimes; using Bane's venom to go on a rampage; attempting to drop a teenage boy into a vat of chemicals; frequently mistreating his henchman and his girlfriend Harley Quinn, as well as abandoning them to be arrested or even to die; and filling the abandoned tunnels and mine shafts beneath Gotham with miles of dynamite to collapse the city to oblivion. That he manages to qualify despite being toned down to all get-out is a testament to how twisted a character Joker is.
Lord Barkis Bittern from Corpse Bride. Despite his uptight snobbery, he at least seems to care about his bride, but in reality he's a male gold digger. In a flashback image, we see a shadowy figure attacking, robbing, and killing Emily (the eponymous Corpse Bride). Later on in the film, it's revealed that Barkis was her fiancÚ and murderer, and responsible for her depression. After marrying Victoria, he plans to rob her blind and murder her as well. Unfortunately, her parents are broke, and marrying Victoria to him for wealth he doesn't actually have. When he learns this, he tries to kill both Victor and Victoria out of frustration.
Antonia Chillingsworth from Dark Fury is the bounty hunter in charge of the mercenary vessel that Riddick, Jack, and Imam run into. She's obsessed with the art of killing and death, while her primary hobby is to collect criminals and notorious fighters to place them in her collection of living statues. There they are frozen so that it takes them a whole day to so much as blink an eye, and they're conscious the whole time, trapped in a nightmare world for hundreds of years to come. She considers this her "artwork", and intends it purely for her own enjoyment. She cares exactly nothing about all the members of her crew she sends against Riddick and die as a result, just that she apparently paid them too much. She wants to make Riddick the latest addition to her collection, and before adding him to the exhibition she throws him and his friends in a pit with people-eating monsters to see him kill something up close. Riddick himself calls her an irredeemable psychopath. The fact that the person saying this is himself pretty much a sociopathic Noble Demon says it all, really.
General Draconis. From his death camps on Venus, starving the populace, to being personally responsible for Nara's parents deaths. Genocide, betrayal, nothing is too much for him. He even betrayed Phaeton when he was relatively sane, and was about to kill Thrax, an honorable Neosapien Warrior who wouldn't kill civilians.note The incident with Thrax deserves an explanation. Thrax was a disgrace because he had spared a member of Exosquad after beating him fair and square. Draconis gave Thrax the chance to "redeem" himself by ordering him to activate a huge bomb in the heart of a city full of civilians. At the last moment Thrax destroyed the activation key and returned, claiming that the humans had disarmed it before the countdown had finished. What Draconis didn't tell Thrax was that the bomb didn't have a countdown; if Thrax had used the activation key it would have blown up immediately and killed him. That's how Draconis knew Thrax had disobeyed his orders — he came back alive. Draconis is so bad that even Phaeton, who is based on Hitler, doesn't seem as bad at first. Of course, Phaeton eventually surpasses Draconis' evil after going insane from Automutation Syndrome.
Phaeton, the ruler of Neo-Sapien empire. He uses words like "equality" and pretends to care about the well being and future of the Neo-Sapiens, but his actions prove this is nothing more than manipulative rhetoric. Before the series start, Phaeton sold out the Neo-Sapien rebellion to save his own skin, and rises to power by initiating genocide on humanity, establishing death camps and killing any who resist-and even those who don't. His tactics include forcible starvation, forced labor or just nasty executions. Not even his own men are exempt. Phaeton is very keen on executing them for minor failures and cloning them. Phaeton's ego and hypocrisy are manifest in how he sends so many of his loyal men to their own deaths on suicidal missions and at the end, even his most loyal aide Livia deserts him for his plans that would have wiped out his own race to secure his own victory. If Phaeton ever held noble ideals, they're gone by the time he enacts his plan at the start of the series and he grows more and more evil and he degrades physically and mentally. He is nothing more than a murderous, power hungry coward by the end and one who would see the entire galaxy burn for the sake of his own power and advancement.
Dr.Albrecht Ketzer turned an entire village of natives in the Amazon and himself into half-plant monstrosities, turned Medusa into a half-plant/half-Neo-Sapien freak, and injected Nara Burns with the same serum. He views her only as an experiment, and wanted to kill all the humans AND Neo-Sapiens in the nearby city.
Owlman from Justice League: Crisis on Two Earths was already a criminal and founding member of the Crime Syndicate of America. Upon discovering the existence of the multiverse, Owlman became enraged by the fact that, with every choice a person makes, they literally create another world in which they made the opposite choice. Determined that his choices had to affect not only his world, but all existence, Owlman journeyed to Earth-Prime, the Earth that supported the existence of all other Earths, planning to destroy all reality in a fit of existential angst. About as selfish as they come, Owlman was reviled even by his compatriots in the CSA.
Vandal Savage from Justice League: Doom, is a conqueror with genocidal plans for the planet. He manages to steal the protocols that Batman designed to defeat the Justice League in case one or more members of the Justice League turn evil. Savage makes these protocols more lethal and sadistic and then uses them to take out the Justice League. After his Legion of Doom seemingly triumphs over the Justice League, Vandal Savage informs them he plans to conquer the world by using a missile that will cause a solar flare that will kill half the world's population. This event will also render the rest of the world's population so weak and helpless that they will naturally accept his leadership.
Eobard Thawne (AKA Professor Zoom) from Justice League The Flashpoint Paradox is the Reverse-Flash and opposes everything Barry Allen stands for. After the world is sent to its twisted alternate state where the world is devastated between a war between Atlantis and the Amazons, Thawne delights in Barry's agony at the new world and enjoys the carnage as it makes his nemesis suffer. When Barry tries to fix the realities, Thawne tries to stop him, meaning he is willing to cause and allow the deaths of countless innocents solely to satisfy his hatred of Barry.
Unalaq, Korra's Evil Uncle of Season 2 of The Legend Of Korra is at first the Holier Than Thou leader of the Northern Water Tribe who is angry how the Southern tribe has lost its spirituality under his elder brother Tonraq. Upon the reappearance of Dark Spirits, Unalaq takes the chance to move in his armies to seize control of the Southern Tribe and has anyone who may oppose removed in a Kangaroo Court before Korra discovers he is the one behind the events that got her father exiled from his home tribe, allowing Unalaq take over. He had gotten barbarians to attack his own home so Tonraq could 'awaken' Dark Spirits to attack their tribe. Unalaq reveals himself as an opportunistic tyrant whose feelings for his own twin children can best be described as 'uncaring' as when his son Desna is injured, almost fatally, Unalaq tells Desna's sister Eska to simply leave him to die as opening the Spirit World is more important. When he gets into the Spirit World, Unalaq forces Korra's cooperation by attacking and threatening to destroy the soul of Jinora, a little girl. When Korra caves in, Unalaq tries to destroy her soul anyways. Unalaq latter assaults the Southern Water tribe and delivers a decisive beating to Tonraq, sparing his life solely so Tonraq can see Unalaq win completely. Unalaq reveals his true plan is to free Vaatu, the spirit of darkness and chaos, to fuse with him into a Dark Avatar in order to usher in tne thousand years of his own dark rule. After he succeeds in merging with Vaatu, Unalaq battles Korra and tears the spirit of light and order, Rava, out of her, brutally attempting to obliterate her. After returning to the material world, he instantly sets out to destroy Republic City and all within it, declaring his rule has begun.
Mega Man: Dr. Wily would qualify, having attempted to send the moon out of its orbit to kill off most of humanity, forcing the survivors (if there were any) to consider him king, so he could prove he was better than Dr. Light. This alone doesn't qualify him, he's also tried to use earthquakes to destroy cities, threatening to destroy them if they don't obey, and he's tortured Mega Man mentally twice in the show, first by making him wonder if he's just a mistake created by Dr. Light, the second time making Proto Man be a Heel Face Mole, even Proto Man considered this act wrong during the plan. And ordered him to kill Mega Man after this.
Mighty Max had some surprisingly dark storylines for a kids' series and some terrifying villains:
Skullmaster, the Evil OverlordBig Bad was always a terrifying villain whenever he appeared. Skullmaster overthrew his previous master and took control of his subterranean kingdom from where he plots world domination. Skullmaster is a sadist, reveling in physical and psychological torture, and engages in both short term brutality and long term gambits. One of his most vile acts was vowing to save an ancient civilization from sinking beneath the sea, lying about it and trapping their souls as his slaves before in present day, sending them after Max's head "attached to the body or not." Responsible for the deaths of multiple heroes throughout the story, Skullmaster even attempted to blackmail Max for his mentor and friend Vergil's life by surrendering his magical cap. When Max turned it over, Skullmaster brutally killed Vergil anyways.
Spike was a psychotic Blood Knight who definitely Would Hurt a Child. Ten Thousand years in the past, Spike led a pack of barbarians to attack a peaceful village when the heroic Norman was just a boy. Refusing offers of peace, Spike brutally attacked and killed Norman's unarmed father before attempting to kill Norman himself. Things went wrong and Spike was buried under the snow for the next 10,000 years, but not before gleefully saying he'd find the boy, kill him and eat his heart. In the present, Spike is no less savage and continues his battle with the now adult Norman until he is defeated. Spike is so evil that Norman feels absolutely fine killing him after Spike has already been defeated, and nobody bothers to complain.
Dr. MacDougal is the first fully human villain to qualify. A Mad Scientist who discovered the existence of werewolves, along with the fact they were peaceful guardians of Scotland.She captured the pack and hooked them up in a rather unpleasant situation where their blood was painfully extracted into a formula for her. After drinking it, Macdougal would achieve the ability to transform herself and used it solely to kill innocent people, becoming the scourge of the highlands. When Max, a ten year old, stumbled upon her lair, Macdougal locks him inside and takes her formula so she can kill him, gleefully referring to him as 'Breakfast.'
Gallaxhar, the alien villain in Monsters vs. Aliens. Humourous sarcasm and hamminess aside, this guy lets his obsession with obtaining Quantonium drive him to unleash a huge robot on San Francisco, which probably would have endangered everyone there had they not already been evacuated. Upon learning that the Quantonium is within Susan, he has no qualms about almost killing Insectosaurus to get her and forcibly drain it out. All this to fuel a machine that creates an army of clones of himself in order to wipe out most of humanity and enslave those left as lab rats. His motive? To rebuild himself a new homeworld, because he himself destroyed his original one and everyone on it. His barely-revealed backstory hints that he has a Freudian Excuse or two, but it's strongly indicated that they are too poor to excuse his actions in any way. By the end, you can be sure he thoroughly deserves getting blown up with the rest of his ship.
Thrax from Osmosis Jones is a sinister virus obsessed with fame and breaking records in the medical books. To this end, Thrax infiltrates humans and sees how fast he can murder them. Upon arriving in the human Frank, in whose body most of the film takes place, Thrax sets about gruesomely murdering whoever crosses his path, while making Frank sicker and sicker. This has the benefit of killing not only Frank, but every being living within him. Thrax even threatens the White-Blood Cell hero, Osmosis Jones, that after Frank is dead, Thrax will gladly go and break his new record on Frank's young daughter.
The Pirates of Dark Water gave us the being behind the titular 'Dark Water', a menacing oily substance that devours whatever it touches and is spreading all throughout the world. By proxy, the Dweller is responsible for countless deaths of places that the Dark Water has devoured. The Dark Dweller is the true Big Bad of the story, a being focused on domination and destruction who plans to unleash its Dark Water throughout the world, focused only on consuming and controlling what it can.
The Grundel from The Real Ghost Busters is an evil spirit who enjoys corrupting children. He has minor Compelling Voice powers: if a child has history of bad actions and is getting into trouble all the time, the Grundel can often convince the child to invite him in. Once invited in, the Grundel will convince the child to commit more bad actions, such as convincing a child named Alec to tamper with the Ghostbusters' proton packs during a school assembly, endangering all the other children present. The more bad actions the child commits, the more the child falls under the Grundel's influence, eventually turning into a Grundel themselves and looking for more kids to corrupt. The Grundel also manages to convince Alec to bring his brother Lee to him so he can corrupt Lee as well, despite Alec's initial protests.
The Grundel returns in Extreme Ghostbusters, 10 years after he was captured by the original Ghostbusters. It is revealed that he has a connection to one of the new Ghostbusters, Kylie. The Grundel tried to corrupt Kylie as a child, but she was too strong willed, so he corrupted her friend Jack instead. Deciding that Kylie's influence will mean that Jack will not be a keeper, the Grundel places Jack in a cocoon for 10 years, so that he will become another Grundel, thus managing to steal ten years of Jack's life. When Kylie confronts the original Grundel about this new Grundel, the Grundel taunts Kylie about their past history and the fate of her former childhood friend. The Grundel later escapes from the containment unit and tries to corrupt Roland's brother Casey. When Kylie manages to confront the Grundel, Kylie says she is not afraid of him, because his powers only work on children. The Grundel knows this, but thinks it would be fun to murder Kylie anyway.
Jenner, the Big Bad of The Secret Of NIMH is a nasty, murderous piece of work. In contrast to his noble brethren amongst the rats of NIMH, Jenner desires nothing but power. When The Hero Mrs. Brisby comes to the rats for help moving her family and house to be safe from a farmer's plow, Jenner sabotages the moving so the wise and kind leader of the rats, Nicodemus is crushed to death, while the Brisby house (and the four Brisby children inside) are trapped and sinking in mud with Jenner not caring about the impending deaths of the kids. When he sees Nicodemus bequeathed a special stone to Mrs. Brisby, Jenner attempts to murder her for it. What makes it even worse is Jenner, like all the rats, owes his very life to Mrs. Brisby's deceased husband and the father of her kids and displays zero remorse or gratitude to Jonathan's memory. After his henchman Sullivan finally has enough with Jenner's lunacy, Jenner slashes his throat and attempts to kill his rival Justin, declaring his only philosophy in life: take what you can when you can.
Dr. Robotnik from Sonic Sat AM, unlike the Affably Evil version of him you'd see in other Sonic cartoons (or the games themselves), is much less pleasant. He is willing to deprive innocent creatures of their free will to get them to work for him, he is willing to turn formerly beautiful communities into severely polluted wastelands, and he doesn't show any remorse for any of this. He turn people into his robotic slaves if they don't obey him, which are quite aware of what's happening to them, and morally objecting to that which their robot bodies are forcing them to do. There are episodes in which some robots are carrying on secret conversations with their loved ones, from before roboticization, only to double over in apparent pain before proceeding to attack said loved ones because of the control Robotnik has over them through said robotic slavery. He even turns the ones who do obey him into robotic slaves.
HIM from We Are the Strange. In his very first scene, he physically assaults his girlfriend and throws her against a wall. In the same scene, he shoos her away, ordering her not to come back until she looks as beautiful as the models on his "girly posters" and tells her how ugly she looks wherever she smiles or talks. Then, later in the film, when he reappears and faces off against one of the heroes he brags about how he had just killed said hero's little boy moments ago.
The Shadow King from Wolverine and the X-Men is a cruel and merciless telepathic mutant who forced a child Storm to be a thief and would berate and threaten her if she did not bring back enough stolen goods. Xavier befriended Storm and defeated the Shadow King. Though his body was destroyed fighting Xavier, his evil spirit lived on and he gained the ability to possess others and force them to do things against their will. When we first see Shadow King in the present, he has possessed a starving man in a desert. When another man comes to help this starving man, The Shadow King possesses the good Samaritan and leaves his original victim to die in the desert. Shadow King later possess Storm herself and forces her to use her Weather Manipulation powers to destroy all Africa, simply to spite her.
