Complete Monster/Cartoon Network

While most villains from Cartoon Network and Adult Swim are mostly Jerkasses at their worst, there are some who take their villainy to the next level.

Adult Swim
"Dan Halen: Do you think this is the only illegal thing I have to do today?"
 * The Boondocks has Ed Wuncler Sr. who starts out as a seemingly friendly business man who's mildly racist. By his 2nd appearance we see the man for what he truly is: a greedy monster who will go to any lengths and sink to any depths to get what he wants. What act cemented this you ask? He tricked an 8-year old girl into working in sweatshop conditions, threatened her father when he tried to get her back, lied about the pony he promised her, and finally stuck her with a $300 bill while he peddled his cruelty-free lemonade.
 * Later, he gave Robert his dream of a soul food restaurant while knowing the whole time what would happen. The restaurant's food was so addictive that people lost their jobs, crime rose, and property values lowered. They eventually got into a lawsuit that shut down the restaurant but Wuncler got what he had planned on: the deed to the nearby Meadowlark Park so he could develop it.
 * Another episode involved him fixing a game of kickball so Huey would start to lose and get agitated in the process and unwittingly hurting a little girl. Then he made Huey think that he had gave said girl a permanent limp so he would leave the sport and Wuncler's own team would win again. And when he wanted Huey to return for his own benefit, he was willing to blackmail him. Ed Wuncler Sr., ladies and gents: a greedy monster deserving of his last name.
 * He had his grandson and his friend set up bombs in a building to kill ONE man. Then, as a result of the building's destruction and the man's death, he would have released merchandise about the single man just to make MORE money than he all ready did, never mind the fact that he's the richest bastard in the entire town. Plus, when his Grandson is dragged out of the house at gunpoint, screaming for his grandpa to help him, Wuncler's response? "Well, go ahead, SHOOT HIM!" Sure, it sounded like an empty threat, but really, deep down, knowing Wuncler, he would have let him shoot his grandson and not have cared in the least.
 * In "Smokin' With Cigawettes", we had Lamilton Taeshawn, who was a slight parody, but still monstrous none the less, and only at the tender age of seven. What made him so horrible you may ask? He recklessly drove around endangering people's lives and refused to apologize when his grandmother asked him to. He proceeded to violently brutalize her when she refuse to by him fried chicken. After that atrocity, he used the same car to spray a combination of urine and hot sauce at innocent people and dropped a doll off a freeway just to cause traffic problems. If that wasn't enough, he then stole her handgun and used it to blackmail Riley into being his friend, planned to rob Ms. Van Housen's house for no reason, and then shot her dog. He shot her dog because he claimed it would bite him, despite the fact that it was chained at the time and nowhere near him. His psychiatrist, Dr. Doomis (a spoof of Dr. Loomis from Halloween), tried rehabilitate him by spending the last 2 years trying to get him into the system and away from society. When said psychiatrist finally turned him into the police for the dog shooting, he blamed Riley, stalked him, and tried to strangle him to death. In the end, he was so evil that the aforementioned psychiatrist leaped from a building just to finish him off after he had fallen off it. You wanna know the real kicker? Lamilton is based on an actual kid, who really did take a joyride in his grandmother's hummer and later attacked her over chicken wings. Some of the things Lamilton says in the episode are quoted from him.
 * Metalocalypse has
 * To put that in perspective, this is a band that is routinely (indirectly) responsible for mass deaths on a global scale. Seeing him working is their Nightmare Fuel.
 * Dan Halen from Squidbillies. He is, in one episode, actually called the personification of evil and a blight on the human race that predates recorded history. Actual examples are shown, such as being a ranking officer in Hitler's Third Reich, spreading the bubonic plague in medieval Europe, causing the extinction of the dinosaurs, and nailing Jesus to the cross. He also overloaded the Large Hadron Collider to intentionally create a black hole to dispose of a prostitute's body, then throws his own mother in as an afterthought.


 * Professor Impossible from The Venture Brothers. On the surface, he's a dorky Mr. Fantastic Expy. But then you find out he keeps his wife isolated because, unlike the Fantastic Four, their powers were useless. Then, when Doctor Venture nearly has an affair with his wife, he responds by leaving him to die in the cold. Brock is barely able to save him, and when he tries to get Ventures son, Hank, treatment (he'd recently swallowed a serum that made him a living bomb), rather than help him, he was ready to shoot. Then, in his second appearance, he's still keeping Sally imprisoned and acting artificial and cold towards his own infant son and forgetting he even exists. Then he breaks down when his wife finally leaves him and is coerced into becoming a supervillain by Phantom Limb, who says it's not much of a stretch for Impossible. He's not joking.
 * And a later episode reveals that he's been using Sally's brother Cody, who's skin bursts into flames when it comes into contact with air, as a power source by constantly keeping him awake, and therefore in constant pain. And he doesn't even show the slightest hint of guilt. Bastard.

Cartoon Network
"Helga: Do you like the coat? It's genuine lawyer."
 * from Ed, Edd 'n' Eddy. . After one of Eddy's failed scams awoke the wrath of the cul-de-sac kids in the Grand Finale, the Eds try to find to get his help. When they find him, he . The cul-de-sac kids . In about five minutes of screen-time, he hit all the criteria for this trope and ended up a dark, unrepentant, irredeemable villain.
 * Adding to it, he comes right out and says this abuse is what he'd done to Eddy his entire life. And he is proud of doing so. ("'Cause he's little. He's always been little.") What truly separates this guy from all the other often Jerkass characters from the show is not only that he's a grown man and a true sadist, but it's that he deals in psychological abuse coupled with the physical abuse, which is only animated in a cartoonishly animated slapstick manner to avoid showing how brutal such treatment would truly look. (And even then, the bruises Eddy receives from the beatdown look very severe!) To drive the point further home, the cul-de-sac kids had spent the entire movie chasing the Edds down take revenge on them. After seeing do this to him and Edd, they . Even the Kanker Sisters are disgusted by him.
 * Oh, and where does all this transpire? Where does this guy live? A trailer at an amusement park. Yes, the implication is obvious: he gets to torment kids every single day. His whole LIFE is just getting off on bullying those smaller and weaker than him.
 * Katz from Courage the Cowardly Dog. Since the show has Negative Continuity, his motives tend to change. In his first appearance, he ran a Hell Hotel where he fed all his guests to spiders for no explained reason. In a later episode, he ran a health spa where he transformed his guests into machines and forced them to fight for his own amusement. In both of these appearances, he didn't seem to get much gain for these action, but did them all with a Slasher Smile on his face. In short, he's an Ax Crazy Serial Killer played straight...on a kid's show!
 * For the record, what does he do when Courage escapes the prison and beats his death trap? Tries to strangle him with his bare hands.
 * There was also that one time he got tired of winning second place at the annual sweets baking contest. His plan to prevent this from happening? Kidnapping the champion and turn her into taffy.
 * Mad Dog from "The Mask". An abusive, possessive, and violent gangleader bent on outright murdering his girlfriend Bunny's best friend, solely because she's her best friend, and buries Bunny up to her neck when she tries to run away the first time. The next time, he runs her down with a car when she tries to escape with Courage. He seems to show compassion to Bunny once, but the rest of his behavior makes it rather obvious that he's just trying to manipulate her into remaining under his paw, a tactic used commonly by abusers in real life. Considering his actions have driven Kitty to be completely unable to face reality and believe all dogs are pure evil, it's frightening to imagine just what he was like to her to make her like that. What makes him stand out is, like Katz, he's played dead straight with no real element of comedy to his character. The most terrifying thing about Mad Dog is that his abuse is played so disturbingly straight that he resembles a real-life abuser...
 * Ben 10 has a few of these.
 * Vilgax, a completely ruthless and evil alien criminal who would cut off a child's arm for an all powerful watch, destroyed a planet for no reason other than to test out a weapon he obtained and, in an episode that ended the series, was going to kill Ben's parents. He was severely decayed and derailed for the Sequel Series, though, a change that many fans continue to argue about.
 * Kevin 11, an eleven year old sociopath of a mutant who'd destroy 2 trains of innocents for cash, killed a police officer with no regrets, killed an alien just to take a ship and crew he'd use to spread terror and death over the galaxy, and whose attacks on Ben and his family are more vicious than most foes, save for the other examples on this page. He also turns down 2 chances at redemption (with Ben even calling him out on how his Freudian Excuse can no longer be a valid way of excusing away his crimes), and when he and Ben are forced to work together, he ends up trying to kill Ben through impaling him. And if you think that's bad, in an Alternate Timeline in the distant future, he tried to murder Ben's son and would've likely killed his own son just to do it. Suffice to say, him getting redeemed for real and joining the main cast of heroes in the sequels is more divisive than what happened to Vilgax!
 * Ghostfreak, who'd possess Ben's cousin Gwen and threatened to make her commit suicide in order to get to Ben and has tried to permanently damage and mutate the Earth to rule over it. And the mutation of Earth is shown on screen and it really isn't pretty.
 * Zombozo, a zombie vampire clown that feeds on laughter, and when he got the chance, he kidnapped Gwen, a 12 year old girl, eating her laughter, the result of which is shown to be her shriveling up and dying slowly. Ironically, he was taken out by Ghostfreak, who'd escape the watch and turn into a Complete Monster on his own. He returns in Ultimate Alien, just as evil as ever. He threatens to kill Ben's parents, and his own hired hands (Charmcaster and Vulkanus) think he's a creepy bastard.
 * From the new Ben 10: Ultimate Alien series, we have Aggregor, who kidnaps aliens from different planets to zap their powers and use them as his own.  And he managed to top himself,
 * Diagon, who's an Expy of the original series' Vilgax in characterization, only with the Cthulhumanoid played up to the ultimate extent. He's also
 * Generator Rex
 * Van Kliess. Held New York City after he had his men get nanite rich soil from his realm underneath it, all the while abusing his Diplomatic Immunity so Rex and Six couldn't touch him. Drinks the blood of Evos who outlived their usefulness or failed him and views everyone and everything as pawns. He even kills a few cops on screen and nearly kills Rex, Six, and their Five-Man Band. Also implied to be behind the entire disaster.
 * Hunter Cain is a fantastic racist who kills Evos left and right even when Rex is trying to cure them. Then he uses his goon squad to piss Rex off in an attempt in discrediting him, and finally, he clones Evos to lure Rex out, was prepared to sacrifice his own men, and then tried to murder Rex when he was unarmed. In his next appearance, he tries to slaughter a whole lot of children.
 * Quarry. He appears 3 times. The first as a gang boss, manipulating several children, and killing underlings who fail him. The next time, he gets a device to destroy organic matter, and decides to blow things up. Later, after a run in with the Big Bad, which put him in pretty bad shape, he reappears, using mind control devices from Providence to make any runaway work for him. He plans to create an army of controlled Evos, then he tries to control Rex, and finally crush him after that fails. To top it off, he's voiced by Mark Hamill.
 * Branden Moses who announced a breakthrough in nanite research that allowed him to dramatically reverse E.V.O. mutations and gave a faux demonstration using an E.V.O. and either an actress with a set of prosthetic tentacles or an E.V.O. with tentacles, playing the part of the "cured E.V.O." Having convinced hundreds, possibly thousands, of people (including Dr. Holiday, who added her sister Beverly Holiday to Brandon's ranks) that he had made a breakthrough, dozens of intelligent but physically deformed, incurable E.V.O.s lined up to be cured. Instead, they were kidnapped and brought to a lab in the Arctic circle where their mutations were amplified and were ready to be auctioned off to the warlord with the deepest pockets.
 * Trigon the Terrible, The Devil Big Bad of the fourth season of Teen Titans doesn't actually do much, as he likes to slouch villainously and let his minions do his work. Still, the first thing he does when making his entrance is killing everyone on Earth (don't worry, they got better). He did that through sacrificing his own daughter Raven, whom he tells exists only to be used for his purposes. Even when Raven proves to be Not Quite Dead, he continues his abuse of her. Once he's become ruler of the dead world and the Titans oppose him, he brings the Titans' darker sides and makes them torment them during the fight. He also sends his demon followers out into the galaxy to claim the rest of the universe, implying his hopes to do what he's done to Earth to countless other worlds. And he's the incarnation of all evil, so it's natural that he's as evil as it gets.
 * Arch Enemy Slade borders on this trope as well. His main goal throughout the series was to find himself an apprentice whom he could mold into being just as cruel and ruthless as he was. First targeting Robin, Slade came up with various schemes to test the Boy Wonder's mettle before finally infecting Robin's friends with nanobots that would destroy them from the inside out should Robin not follow Slade's every command. When his plans for Robin were thwarted, Slade next turned his attention to Terra. Taking advantage of her status as an outsider who would never be accepted because of her destructive powers, Slade manipulated her into joining and befriending the Titans, betraying them and finally trying to kill them. After Terra finds herself in over her head while fighting the Titans and retreats, Slade physically abuses her for defying his orders. When Terra tries to quit her apprenticeship, Slade reveals that the suit he gave her to enhance her powers also gave him complete control over her body and vowed that he would never let her go. Though Slade dies when Terra rebels against him, he is eventually resurrected by the demonic Omnicidal Maniac Trigon, to act as The Dragon. Ever The Sociopath, Slade took a vicious pleasure in his work towards the ensuring the apocalypse, mind raping Raven with visions of her destiny as the Anti Christ and selling out all of humanity to Trigon in exchange for Trigon giving him back his soul. Even when Slade rebels against Trigon, it isn't out of altruism, but because Trigon refused to honor their bargain. What truly makes Slade so heinous is that he is the embodiment of a child predator, and he plays it completely straight.
 * The one-shot villain Professor Dick Hardly from The Powerpuff Girls, despite being human, is more of a monster than most villains of the show. Introduced as the sleazy college roommate of Professor Utonium, Dick quickly sees the potential of the Powerpuff Girls as a way to get rich quick. Getting the girls to supply him with Chemical X, Dick makes his own knock-offs of the girls and starts a business selling these copies as superheroes. Due to Dick's greed, however, these knock-offs have been created with minimum materials and Chemical X, meaning that, even though they are aware, they are mentally stunted and physically deformed. When the effort of superheroing causes the knock-offs to literally fall apart, Dick's happy because it means he gets to sell even more copies. At one point Dick notices one of his knock-offs is a perfect Buttercup copy, his response is to order the girl melted down for her "excessive" Chemical X. The episode's climax has Dick capturing the Powerpuff Girls and killing them slowly by draining them of their Chemical X while their father was watching. When Utonium offers to be a slave, making Chemical X for Dick for the rest of his life if Dick will let the girls live, Dick only laughs and says he'll kill the girls and keep Utonium as a slave. Greed incarnate, Dick was notable for being the only villain on the show to be played completely straight, with no humorous quirks to detract from his viciousness. He's one of the show's most evil and memorable villains despite only appearing once in the entire show. That may explain why he's the sole human character to die in the entire show.
 * The only recurring villain considered to be even close to pure evil is Him, who's actively described as the most evil being out there. That's right: in the context of the Powerpuff Girls universe, Dick Hardly is worse than the Devil.
 * In Sym-Bionic Titan, we have General Modula (despite the fact that it remains to be seen if he is truly in control or the same one they once knew), who is making himself into a big one. First of all, he betrayed his own homeworld, slaughtered and enslaved the inhabitants, and actively hunted down any resistance he could find. He treats his own mooks as cannon fodder, and if they fail to meet his expectations, he kills them without even moving from his spot.
 * Codename: Kids Next Door had one in Grandfather from Operation Zero. While the rest of the villains were too silly to be viewed as real threats, although some did cross the Moral Event Horizon, such as Mr. Boss sending his employees' daughters to Pluto or Grandma Stuffum force feeding children until they explode. They are still all either too Lawful Stupid and/or Stupid Evil to be taken seriously. The rest are either Card Carrying Villains or, in Toilenator's case, a Harmless Villain, and their crimes aren't heinous at all. Even Father suffered from Villain Decay, but not Grandfather...He's an Evil Overlord who ruled the world with an iron fist a long time ago, before being defeated by Numbuh Zero. His first act after being revived is to try to turn everyone in the entire world into SenorCitizombies just because kids annoy him, and that's not even going into how much of an Abusive Parent he is. Some of the other villains are shown to at least like their own kids; he's the reason Father is the person he is now, and in one episode, we see Grandfather somehow left him a completely traumatized vegetable, for crying out loud! Even his favorite son isn't free from his abuse: when he tried to stand up to him, he tried to incinerate him with no remorse.
 * What's even worse is that children were shown working like slaves in his Industrial Age factories, and to anyone who paid attention in history class, that actually did happen and it was a Fate Worse Than Death.
 * Even worse: in Real Life, the factories were at least building something useful. Grandfather made them work like slaves to create tapioca pudding, solely for his own consumption. He made children work like slaves for something completely trivial and solely for himself.
 * Adventure Time: The Lich is mentioned in passing at the end of Season 1, in reference to his defeat at the hands of the hero Billy. Then we meet him in person in the Season 2 finale. He's an Omnicidal Maniac, not because of some great tragedy in his past that's explained to us - he just wants to wipe out all life. He almost takes control of Finn with his Compelling Voice and takes up Body Surfing at the destruction of his physical body, turning Princess Bubblegum into an Attack of the 50-Foot Whatever Eldritch Abomination. He later ends up killing and possessing the body of Billy as part of a complex gambit to get a Reality Warper to grant his wish for the extinction of all life across The Multiverse; murdering dream Prismo as well as Prismo's physical body, the latter solely For the Evulz, then breaking the universe's worst criminals our of their cosmic jail, all in order to create an unstoppable army for himself to lead in wiping out all life, one planet at a time. The Lich is also heavily implied to have been involved with the destruction of mankind and one of the reasons why the show takes place in a world After the End. While the show's other villains are sympathetic or comedic, he's played deadly straight and voiced by Ron Perlman. He makes a point of targeting any weapon that was effective against him in the previous battle, so he stands above the show's other villains in competence as well. Finally, he's freaky - especially when his skull is about to break and he just starts laughing...
 * In Jonny Quest: The Real Adventures no Monster of the Week was as horrible as the succubus/vampire known as Elise Lenior from Eclipse.Appearing as an innocent young woman on the run from evil men, Elise maintained her youth and beauty by draining the life from beautiful, innocent women. The man hunting her had lost his sister to her years past. Elise murdered the men who tried to tail her, and later mind controlled Hadji into her slave to bring Jessie to her for her food source. When her right-hand man protested about Elise trying to replace him with Hadji, Elise declared he was right and sucked the life from him as well. When her deadline of an eclipse was approaching, Elise abandoned all pretense of charm and subtlety and assumed her monstrous true form to kill everyone around and drain Jessie's life.
 * Star Wars: The Clone Wars gave us General Pong Krell during the Umbaran four-parter. Essentially a Fantastic Racist Jerkass General Ripper who abuses the clones and treats them like cannon fodder, perfectly willing to throw them away with strategies bound to fail. Then he orders the death of Jesse and Fives, as well as a court martial for disobeying orders after they saved the day by doing so. Then he truly crosses the Moral Event Horizon-he plays two armies of Clone Troopers against each other by saying that there were infiltrators, having them kill each other. And shortly after that, he confesses that he's been trying to lose as many clones as possible because his plan was to sabotage the Republic war effort from within in order to ingratiate himself to Count Dooku and become the Sith Lord's next apprentice just to escape his premonition of Order 66.
 * Keeper Agruss the Zygerrian is a slaver, which is bad in itself, but goes above and beyond the call of duty on that. In particular, he has no problem casually murdering dozens of slaves if it means breaking a Jedi, tortures and kills other slaves for Obi-Wan's defiance, not only making his help unproductive but actually alienating those he seeks to protect. He truly earns his credentials at the end. The Republic has arrived and it's quite clear he's lost. What does he do? Set the system to dump the slaves into the abyss, smashes the panel to prevent Obi-Wan from saving them (Ahsoka manages to get them to safety), then gloats about how Obi-Wan can't retaliate because he's a Jedi. His death at Rex's hands was very deserved. Even the queen had a redeeming moment at the end. This guy was just straight-up evil.
 * Darth Sidious, naturally, who was planning on performing possibly lethal surgery on said infants, while in a red-tinted laboratory that even the most mad Mad Scientist would be afraid to work in, over a lava lake on the planet which is basically the Star Wars version of Hell.
 * Believe it or not, Scooby Doo has had these!
 * The Snow Ghost/. When you try to slice a 15-year-old girl in half with a lumber saw, there's really no going back for you. Notably, he's played completely seriously, with not a gag in sight.
 * Zen Tuo/ was just as bad, except replace Velma with Shaggy and "sliced in half" with blown up. Exact same motive as , too, and exact same lack of funny.
 * The last-revealed villain of Zombie Island, . He seems like a nice guy at first, . Don't let it fool you. The  thing? A lure to get people to trust him, so he can  where he and his accomplices . His initial appearance contrasted with the revelation of his evil deeds and his true nature makes him chillingly similar to a believable Serial Killer. What's especially jarring is the contrast between him and the other 2 antagonists of the piece; specifically, they are . This guy, though,  It seems rather unfair, then, that.
 * Scooby Doo Mystery Incorporated has one in the form of
 * The Secret Saturdays: V.V. Argost, big time. As the Himalayan Yeti, Argost murdered people for pleasure, preying upon the humans who wandered through the mountains and taking "souvenirs" off their bodies. Two of his victims were Drew and Doyle Saturdays' parents. When confronted with this, Argost only says he can't be bothered to remember all of the people he's killed. Throughout the series, Argost was obsessed with finding Kur, a god who had the power to control all cryptids. Eventually Argost discovered that Zak Saturday, was Kur himself, and so Argost began plotting to steal the boy's power. Eventually Argost managed to succeed in this by draining the god power out of Zak Monday, the evil alternate dimension counterpart of Zak Saturday. This had the side effect of killing the boy. With his newfound powers, Argost ordered his cryptid army to wage war against every major human capital city, with the ultimate goal to Kill All Humans and rule all cryptids. Though already possessing a god's power, Argost craved more power still, and so he killed Zak Saturday to drain his power as well, just as he did to Monday. Ever the showman, Argost took to committing atrocities with a theatrical flourish and dry humor, relishing the screams of his victims and considering the destruction of mankind as just another one of his grand performances.
 * Krytus, the 3rd Big Bad from Hot Wheels Battle Force 5. He's known as the most malicious being in the entire multiverse (this was said by another Big Bad!) and evil incarnate. He restarted a eons old war between the Red and Blue Sentients simply because he saw the Blues as weak and inferior and desired to conquer the entire multiverse. When Sage froze the Red Sentients, the war continued and Krytus carried out a genocide on the Blues. At one point, it's revealed that he had several thousand Blue Sentients tortured to death and the one who managed to enter hibernation to escape him was punished by having his body sabotaged, dooming him when he woke up. Krytus's first action after being freed from his prison is to throw the one who released him off a cliff! He then spends most of the series trying to kill Sage (his own sister), who is a pacifist who only wants peace. At one point, after being forced into an Enemy Mine with Vert to escape the Shadow Zone, he sets up an ambush for Vert the moment they're out of it, unlike previous villains who normally had the honor to let the Battle Force 5 go after an Enemy Mine. Not even the other villains are safe from his wrath, as he starts an Enemy Civil War among the Vandals through Grimian. But what solidifies this is at the season finale, when he and Sage finally have a confrontation. After asking Sage Was It Really Worth It? to imprison the Red Sentients, she replies that if she hadn't, Krytus would've endangered not only the Blue Sentients, but the entire multiverse. Krytus actually agrees with her, fully admitting that not only does he know what he's doing is evil and wrong, he doesn't care so long as he can conquer the multiverse. The only reason he tried to free the Red Sentients was because he wanted an army to conquer the multiverse with, not out of concern for them.
 * Would you believe Totally Spies had one? Helga Von Guggen is a greedy fashion designer who, to save money on materials, decides she'll start making "seamless" fur coats. How does she go about this? By kidnapping innocent people, injecting them with a serum that turns them into Petting Zoo People, then skinning them alive in what appears to be a giant industrial crusher. Is it any wonder that she became one of the show's main villains? Seriously, how's this for an Establishing Character Moment?


 * The aptly-named Atrocitus from Green Lantern the Animated Series. He is the leader of the Red Lanterns and the reason that Razer's wife is dead. He is dedicated to the destruction of the Green Lantern Corps, having many of them murdered by his Red Lantern followers. First showing his ruthlessness in ordering a colony world full of innocent civilians destroyed, Atrocitus later revealed he had destroyed worlds to fill survivors with rage and recruit them as Red Lanterns. Unlike his comics counterpart, a Tragic Villain at worst and an Anti-Hero at best, Atrocitus in the show delighted over the pain he caused innocents and took sadistic pleasure in his actions. Even though he himself had once lost a homeworld, he gloated over inflicting the same agony on others like Razer.
