* ''WesternAnimation/CourageTheCowardlyDog'': [[CatsAreMean Katz]] stands out in a children’s cartoon as an AxCrazy SerialKiller played straight. While his motives tend to change due to the show’s NegativeContinuity, each episode he appears in generally has him using some sort of illegitimate business as a front for committing murders, [[FridgeHorror his list of past victims strongly implied to be quite long]]. In his first appearance, for example, he ran a HellHotel where he fed all his guests to spiders. Other episodes have seen him [[BalefulPolymorph transforming the guests of his health spa]] into machines and forcing them to fight to the death for his entertainment, threatening to turn Muriel into candy as revenge for [[SecondPlaceIsForLosers her always beating him in a candy-making competition]], and trying to blow up a submarine full of people to drive a rival vacation submarine company out of business. In most of his appearances, he challenges Courage to some sort of sport [[{{Sadist}} solely to drag out the dog’s suffering for as long as he can]]. In a series that was already in no short supply of NightmareFuel, Katz [[KnightOfCerebus still stood out]] as [[VileVillainSaccharineShow the absolute worst the show had to offer]].

* ''WesternAnimation/CourageTheCowardlyDog''. Katz's motives tend to change due to the show's NegativeContinuity, but what he does is always horrible. In his first appearance, he ran a HellHotel where he fed all his guests to spiders, taking sadistic delight in doing so. In a later episode, he ran a health spa where he [[BalefulPolymorph 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 actions, but did them all with a SlasherSmile on his face. In short, he's an AxCrazy SerialKiller played straight...''on a kid's show!'' What makes Katz even worse is the fact that the family is heavily implied to just be the latest in a long line of victims to fall into his clutches.

* ''WesternAnimation/ThePowerpuffGirls'': Season 4's two-parter "Knock if Off" has one-shot villain Professor [[MeaningfulName Dick]] [[BlondGuysAreEvil Hardly]]. Introduced as the [[{{Jerkass}} 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 [[BodyHorror 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 real Powerpuff Girls and killing them slowly by draining them of their Chemical X. 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 Hardly was notable for being the only villain on the show to be played [[KnightOfCerebus completely seriously]], with [[VileVillainSaccharineShow no humorous quirks to detract from his viciousness]].

[[caption-width-right:320:Even to be a one-shot villain, he is even ''worse'' than {{Satan}} InUniverse!]]

While most villains from Cartoon Network and Adult Swim are mostly {{jerk|ass}}s at their worst, there are [[CompleteMonster some who take their villainy to the next level]].

* The Lich from ''WesternAnimation/AdventureTime'' is an EvilSorcerer who desires nothing less than the [[OmnicidalManiac extinction of all life]]. While most of the series' antagonists have sympathetic moments or funny quirks that add levity to their crimes, the Lich is the only villain to always be played [[KnightOfCerebus absolutely seriously]]. His attempts at wiping out all life has included possessing Princess Bubblegum, going OneWingedAngel, and rampaging through the Candy Kingdom; killing and possessing the body of [[spoiler:Billy]] as part of a complex gambit to get a RealityWarper to grant his wish for the extinction of all life across TheMultiverse; murdering [[spoiler:dream Prismo]] as well as [[spoiler:Prismo's physical body]], the latter solely ForTheEvulz, 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 AfterTheEnd.
* Aggregor from ''WesternAnimation/Ben10UltimateAlien'' was an Osmonian warlord who was 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 out 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 attempted to kill and absorb a baby alien capable of {{Reality Warp}}ing to complete his ascension into godhood.
* Katz from ''WesternAnimation/CourageTheCowardlyDog''. Since the show has NegativeContinuity, his motives tend to change, but what he does is always horrible. In his first appearance, he ran a HellHotel where he fed all his guests to spiders, taking sadistic delight in doing so. In a later episode, he ran a health spa where he [[BalefulPolymorph 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 SlasherSmile on his face. In short, he's an AxCrazy SerialKiller played straight...''on a kid's show!'' What makes Katz even worse is the fact that the family is heavily implied to just be the latest in a long line of victims to fall into his clutches.

** Van Kleiss, the ruthless dictator of Abysus. Though he uses propaganda to claim he's trying to build a better world for [=EVOs=], in actuality Van Kleiss cares only for his dream of world domination, and nothing for his subordinates. Van Kleiss makes a habit of [[TakenForGranite petrifying EVOs]] by sucking the nanites out of them, or [[TragicMonster turning regular people into EVOs]] to act as muscle for him, not caring that such an action could leave them permanently transformed. In his bid for power Van Kleiss murdered Rex's parents, experimented on his WoobieDestroyerOfWorlds follower to amplify her powers while causing her excruciating pain, and threatened a little girl to force her father to turn the people of New York into his zombie army.
** Hunter Cain is a {{Fantastic Racis|m}}t 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 [[MoralEventHorizon 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.
** 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.
* Krytus, the 3rd BigBad from ''WesternAnimation/HotWheelsBattleForce5''. He's known as the most malicious being in the entire multiverse ([[EvilerThanThou this was said by]] ''[[EvilerThanThou another]]'' BigBad!) 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 [[BigGood 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 [[SealedEvilInACan being freed from his prison]] is to [[YouHaveOutlivedYourUsefulness 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 EnemyMine 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 EnemyMine. Not even the other villains are safe from his wrath, as he starts an EnemyCivilWar 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 WasItReallyWorthIt to imprison the Red Sentients, she replies that [[GodzillaThreshold 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. [[spoiler:He's also the sole BigBad to earn a FateWorseThanDeath, being imprisoned in ice on another world for all eternity.]]
* In ''WesternAnimation/JonnyQuestTheRealAdventures'' no MonsterOfTheWeek was as horrible as the succubus/vampire known as Elise Lenior from ''Eclipse.''[[WoundedGazelleGambit 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 [[MindRape 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.
* ''WesternAnimation/ThePowerpuffGirls'' gives us one-shot villain Professor [[MeaningfulName Dick]] [[BlondGuysAreEvil Hardly]] (pictured above, after his transformation). Introduced as the [[{{Jerkass}} 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 [[BodyHorror 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 real Powerpuff Girls and killing them slowly by draining them of their Chemical X. 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 Hardly was notable for being the only villain on the show to be played [[KnightOfCerebus completely seriously]], with [[VileVillainSaccharineShow no humorous quirks to detract from his viciousness]].

** Jacques from ''[[WesternAnimation/ScoobyDooOnZombieIsland Zombie Island]]'' stands out as a stark contrast with his two WoobieDestroyerOfWorlds co-conspirators. While his partners had no idea that praying to their cat god for help in their pursuit of vengeance would lead to their transformation into monsters, Jacques was a normal man who willingly became a monster to make himself immortal. For years he's been using his ferry to escort people to Moonscar Island, only for him and his partners to drain the life from them. Afterwards their victims are left to wander the island as zombies, [[AndIMustScream aware but unable to move on to the afterlife]].
** ''[[ScoobyDooMysteryIncorporated Mystery Incorporated]]'' has one in the form of the BiggerBad, the [[EldritchAbomination Nibiru Entity]]. A member of a normally benevolent inter-dimensional alien race called the Anunnaki, his own kind considers him the most evil member of their entire species. He's spent untold centuries corrupting and manipulating the people around him, especially the {{Team Pet}}s of mystery solving teams, by perverting his species' ability to use animals as mediums to communicate, all working towards [[SealedEvilInACan freeing him from his prison]]. In the process he's ruined and ended countless lives through his {{Unwitting Pawn}}s (including [[BigBad Professor Pericles]], who the Entity turned into a murderous psychopath) without a second thought. When he's finally released in the SeriesFinale, he proceeds to [[YouHaveOutlivedYourUsefulness gleefully eat his loyal minions alive]] along with Mr. E. He follows this by turning Crystal Cove into HellOnEarth and devouring the ''entire'' town with sadistic glee, planning to move on to the rest of the universe when he's done, all for the sake of power. 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.
* V.V. Argost from ''WesternAnimation/TheSecretSaturdays'' is the FauxAffablyEvil nemesis of the Saturday family and, in actuality, a cryptid himself. As the Himalayan Yeti, [[ForTheEvulz 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 [[ButForMeItWasTuesday 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 [[KidHero 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. [[WouldHurtAChild 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 KillAllHumans 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, [[LovesTheSoundOfScreaming relishing the screams of his victims]] and considering the destruction of mankind as just another one of his grand performances.
* General Modula from ''WesternAnimation/SymBionicTitan''. Originally a reasonable, heroic man, all of the good traits Modula once had withered and died when his former best friend, the King of Galaluna, mistakenly [[LeftForDead left him for dead]]. Possessing now only a lust for vengeance against his former comrade, and a thirst for conquest, Modula betrayed his homeworld to the Mutradi monsters and slaughtered and enslaved its inhabitants. Fearing that only the princess of Galaluna, Illana, can restore the hopes of the planet's people and have them rally against him, Modula sends countless monsters to ravage the planet where she's hiding out. It's made clear in the show that the buildings and cities his monsters destroy [[ConvenientlyEmptyBuildings are not conveniently empty]], and at one point Modula goes so far as to send a living bomb capable of wiping out an entire planet to earth all so he can kill one girl. While seemingly stoic on the outside, in actuality Modula is utterly AxeCrazy and [[HairTriggerTemper is willing to kill anyone, even his own minions, at the drop of a hat]]. Instances of this can be seen when he smiles as he snaps the neck of a resistance fighter and when he casually vaporizes a minion who had failed him without even getting up from his chair.
* ''WesternAnimation/TotallySpies'' has Helga Von Guggen, a greedy fashion designer. She makes "seamless" fur coats by kidnapping innocent people, injecting them with a serum that turns them into PettingZooPeople, then skinning them alive in what appears to be a giant industrial crusher. She brags about one of her coats, claiming that it's "genuine lawyer".

* [[UltimateEvil The Lich]] from ''WesternAnimation/AdventureTime'', is an EvilSorcerer who desires nothing less than the [[OmnicidalManiac extinction of all life]]. While most of the series’ antagonists have sympathetic moments or funny quirks that add levity to their crimes, the Lich is the only villain to always be played [[KnightOfCerebus absolutely seriously]]. After being destroyed by Finn before he could regain his full powers, the Lich [[GrandTheftMe hopped into the body of Princess Bubblegum]] and manipulated Finn into gathering materials the Lich could use to revive himself. Once those materials were obtained, the Lich went OneWingedAngel and started rampaging through the Candy Kingdom. Defeated again, the Lich made a comeback by killing the hero Billy and using Billy's body to once again manipulate Finn in his schemes. Eventually, the Lich manages to open a portal to the center of {{The Multiverse}} and get a wish from the RealityWarper Prismo, which the Lich then uses to wipe out all life, not just in Finn’s world, but in all {{The Multiverse}}'s dimensions. 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 AfterTheEnd.

* ''WesternAnimation/ThePowerpuffGirls'' gives us one-shot villain Professor [[MeaningfulName Dick]] [[BlondGuysAreEvil Hardly]] (pictured above, after his transformation). Introduced as the [[{{Jerkass}} 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.

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 real Powerpuff Girls and killing them slowly by draining them of their Chemical X. 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 Hardley was notable for being the only villain on the show to be played [[KnightOfCerebus completely seriously]], with [[VileVillainSaccharineShow no humorous quirks to detract from his viciousness]].

* The aptly-named [[NamesToRunAwayFromReallyFast Atrocitus]] from ''WesternAnimation/GreenLanternTheAnimatedSeries''. He is the leader of the Red Lanterns and the reason that Razor's wife is dead--causing the civil war that led to her death, [[MoralEventHorizon just so he'd become a Red Lantern]]. While he still has the same tragic backstory as his comic counterpart, any sympathy ends with the fact that he has [[ManipulativeBastard hypocritically been responsible for many of his converts]].

* ''WesternAnimation/ThePowerpuffGirls'' gives us one-shot villain Professor [[MeaningfulName Dick]] [[BlondGuysAreEvil Hardly]] (pictured above, after his transformation). 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.

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 real Powerpuff Girls and killing them slowly by draining them of their Chemical X. 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 Hardley was notable for being the only villain on the show to be played [[KnightOfCerebus completely seriously]], with [[VileVillainSaccharineShow no humorous quirks to detract from his viciousness]].

* Slade was one of the {{Big Bad}}s of ''WesternAnimation/TeenTitans'' and was a cold, manipulative criminal mastermind. Slade's 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 [[PeoplePuppets 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 OmnicidalManiac, Trigon, to act as the demon's [[TheDragon dragon]]. Slade took a vicious pleasure in his work towards the ensuring the apocalypse, [[MindRape mind raping]] Raven with visions of her destiny as the AntiChrist 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.

* Katz from ''WesternAnimation/CourageTheCowardlyDog''. Since the show has NegativeContinuity, his motives tend to change, but what he does is always horrible. In his first appearance, he ran a HellHotel where he fed all his guests to spiders, taking sadistic delight in doing so. In a later episode, he ran a health spa where he [[BalefulPolymorph 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 SlasherSmile on his face. In short, he's an AxCrazy SerialKiller played straight...''on a kid's show!'' What makes Katz even worse is the fact that the family is heavily implied to just be the first in a long line of victims to fall into his clutches.

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.

* Would you believe ''WesternAnimation/TotallySpies'' 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 PettingZooPeople, 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 EstablishingCharacterMoment?
--> '''Helga''': Do you like the coat? It's genuine lawyer.

While most villains from Cartoon Network and Adult Swim are mostly [[{{Jerkass}} jerks]] at their worst, there are [[CompleteMonster some who take their villainy to the next level]].

'''NOTE: Any changes (additions, removals, edits) should be discussed [[http://tvtropes.org/pmwiki/posts.php?discussion=6vic3f9h1cy5qivsenw8llok here]].'''

* Eddy's Brother from ''WesternAnimation/EdEddNEddysBigPictureShow''. While there have been many hints throughout the show that this guy was not as nice as Eddy built him up to be, just how horrible he was wasn't seen until the final ten minutes of the movie. It turns out that Eddy's Brother has been abusing Eddy for the latter's entire life. After the cul-de-sac kids had been hurt by one of the Eds' scams, the Eds seek refuge at Eddy's Brother's place to escape their peers' wrath. At first, Eddy's Brother acts nice and helpful, but then shows his true colors by viciously beating Eddy ForTheEvulz. For the first time on the show the injuries aren't PlayedForLaughs and it's stressed that Eddy is ''really'' being hurt this time. When Double D tries to help Eddy, Eddy's Brother responds by beating up Double D too. Keep in mind this is a fully grown adult who is beating the pulp out of two twelve-year-old boys. The level of abuse Eddy's Brother dishes out and the sheer sadistic joy he takes in it, are enough to get both the cul-de-sac kids and the Kanker sisters, who have frequently abused the Eds themselves throughout the series, to pull an EvenEvilHasStandards moment and stand up to him. Once Eddy's Brother has been knocked out, Eddy has an emotional breakdown, and tearfully reveals that his entire life has been shaped by his brother's abuse and corruptive influence and he's the reason why Eddy turned out to be the {{Jerkass}} scam artist he was presented as through the rest of the series.

* ''WesternAnimation/StarWarsTheCloneWars'': During the Umbaran four-parter, we see General Pong Krell. Essentially a [[FantasticRacism Fantastic Racist]] JerkAss who abuses the clones and [[WhatMeasureIsANonHuman treats them like cannon fodder]], perfectly willing to throw them away with strategies bound to fail. In the end, he reveals that he knew what he was doing was wrong and declares himself a Sith, willing to join Dooku just to escape his premonition of [[RevengeOfTheSith Order 66]].

* Jacques from ''WesternAnimation/ScoobyDooOnZombieIsland'' stands out as a stark contrast with his two WoobieDestroyerOfWorlds co-conspirators. While his partners had no idea that praying to their cat god for help in their pursuit of vengeance would lead to their transformation into monsters, Jacques was a normal man who willingly became a monster to make himself immortal. For years he's been using his ferry to escort people to Moonscar Island, only for him and his partners to drain the life from them. Afterwards their victims are left to wander the island as zombies, [[AndIMustScream aware but unable to move on to the afterlife]].

* ''ScoobyDooMysteryIncorporated'' has one in the form of the [[EldritchAbomination Nibiru Entity]]. A member of a normally benevolent interdimensional alien race called the Anunnaki, his own kind considers him the most evil member of their entire species. He's spent untold centuries corrupting and manipulating the people around him, especially the {{Team Pet}}s of mystery solving teams, by perverting his species' ability to use animals as mediums to communicate, all working towards [[SealedEvilInACan freeing him from his prison]]. In the process he's ruined and ended countless lives through his {{Unwitting Pawn}}s (including [[BigBad Professor Pericles]], who the Entity turned into a murderous psychopath) without a second thought. When he's finally released in the SeriesFinale, he proceeds to [[YouHaveOutlivedYourUsefulness gleefully eat his loyal minions alive]] along with Mr. E. He follows this by turning Crystal Cove into HellOnEarth and devouring the ''entire'' town with sadistic glee, planning to move on to the rest of the universe when he's done, all for the sake of power. 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 aptly-named [[NamesToRunAwayFrom Atrocitus]] from ''WesternAnimation/GreenLanternTheAnimatedSeries''. He is the leader of the Red Lanterns and the reason that Razor's wife is dead-causing the civil war that led to her death, [[MoralEventHorizon just so he'd become a Red Lantern.]] While he still has the same tragic backstory as his comic counterpart, any sympathy ends with the fact that he has [[ManipulativeBastard hypocritically been responsible for many of his converts.]]

* Katz from ''CourageTheCowardlyDog''. Since the show has NegativeContinuity, his motives tend to change, but what he does is always horrible. In his first appearance, he ran a HellHotel where he fed all his guests to spiders, taking sadistic delight in doing so. In a later episode, he ran a health spa where he [[BalefulPolymorph 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 SlasherSmile on his face. In short, he's an AxCrazy SerialKiller played straight...''on a kid's show!'' What makes Katz even worse is the fact that the family is heavily implied to just be the first in a long line of victims to fall into his clutches.
* Eddy's Brother from ''EdEddNEddysBigPictureShow''. While there have been many hints throughout the show that this guy was not as nice as Eddy built him up to be, just how horrible he was wasn't seen until the final ten minutes of the movie. It turns out that Eddy's Brother has been abusing Eddy for the latter's entire life. After the cul-de-sac kids had been hurt by one of the Eds' scams, the Eds seek refuge at Eddy's Brother's place to escape their peers' wrath. At first, Eddy's Brother acts nice and helpful, but then shows his true colors by viciously beating Eddy ForTheEvulz. For the first time on the show the injuries aren't PlayedForLaughs and it's stressed that Eddy is ''really'' being hurt this time. When Double D tries to help Eddy, Eddy's Brother responds by beating up Double D too. Keep in mind this is a fully grown adult who is beating the pulp out of two twelve-year-old boys. The level of abuse Eddy's Brother dishes out and the sheer sadistic joy he takes in it, are enough to get both the cul-de-sac kids and the Kanker sisters, who have frequently abused the Eds themselves throughout the series, to pull an EvenEvilHasStandards moment and stand up to him. Once Eddy's Brother has been knocked out, Eddy has an emotional breakdown, and tearfully reveals that his entire life has been shaped by his brother's abuse and corruptive influence and he's the reason why Eddy turned out to be the {{Jerkass}} scam artist he was presented as through the rest of the series.
* ''GeneratorRex'':
** Van Kleiss from ''WesternAnimation/GeneratorRex'', the ruthless dictator of Abysus. Though he uses propaganda to claim he's trying to build a better world for [=EVOs=], in actuality Van Kleiss cares only for his dream of world domination, and nothing for his subordinates. Van Kleiss makes a habit of [[TakenForGranite petrifying EVOs]] by sucking the nanites out of them, or [[TragicMonster turning regular people into EVOs]] to act as muscle for him, not caring that such an action could leave them permanently transformed. In his bid for power Van Kleiss murdered Rex's parents, experimented on his WoobieDestroyerOfWorlds follower to amplify her powers while causing her excruciating pain, and threatened a little girl to force her father to turn the people of New York into his zombie army.
** Hunter Cain is a [[FantasticRacism 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 [[MoralEventHorizon 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.

* Krytus, the 3rd BigBad from ''HotWheelsBattleForce5''. He's known as the most malicious being in the entire multiverse ([[EvilerThanThou this was said by]] ''[[EvilerThanThou another]]'' BigBad!) 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 [[BigGood 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 [[SealedEvilInACan being freed from his prison]] is to [[YouHaveOutlivedYourUsefulness 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 EnemyMine 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 EnemyMine. Not even the other villains are safe from his wrath, as he starts an EnemyCivilWar 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 WasItReallyWorthIt to imprison the Red Sentients, she replies that [[GodzillaThreshold 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. [[spoiler:He's also the sole BigBad to earn a FateWorseThanDeath, being imprisoned in ice on another world for all eternity.]]
* Professor Dick Hardley from the ''PowerPuffGirls''. 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 [[BodyHorror 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 real Powerpuff Girls and killing them slowly by draining them of their Chemical X. 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 Hardley was notable for being the only villain on the show to be played completely seriously, with no humorous quirks to detract from his viciousness.
* Jacques from ''ScoobyDooOnZombieIsland'' stands out as a stark contrast with his two WoobieDestroyerOfWorlds co-conspirators. While his partners had no idea that praying to their cat god for help in their pursuit of vengeance would lead to their transformation into monsters, Jacques was a normal man who willingly became a monster to make himself immortal. For years he's been using his ferry to escort people to Moonscar Island, only for him and his partners to drain the life from them. Afterwards their victims are left to wander the island as zombies, [[AndIMustScream aware but unable to move on to the afterlife]].
* V.V. Argost from ''TheSecretSaturdays'' is the FauxAffablyEvil nemesis of the Saturday family and, in actuality, a cryptid himself. As the Himalayan Yeti, [[ForTheEvulz 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 [[ButForMeItWasTuesday 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 [[KidHero 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. [[WouldHurtAChild 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 KillAllHumans 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, [[LovesTheSoundOfScreaming relishing the screams of his victims]] and considering the destruction of mankind as just another one of his grand performances.
* ''StarWarsTheCloneWars'': During the Umbaran four-parter, we see General Pong Krell. Essentially a [[FantasticRacism Fantastic Racist]] JerkAss who abuses the clones and [[WhatMeasureIsANonHuman treats them like cannon fodder]], perfectly willing to throw them away with strategies bound to fail. In the end, he reveals that he knew what he was doing was wrong and declares himself a Sith, willing to join Dooku just to escape his premonition of [[RevengeOfTheSith Order 66]].
* General Modula from ''SymBionicTitan''. Originally a reasonable, heroic man, all of the good traits Modula once had withered and died when his former best friend, the King of Galaluna, mistakenly [[LeftForDead left him for dead]]. Possessing now only a lust for vengeance against his former comrade, and a thirst for conquest, Modula betrayed his homeworld to the Mutradi monsters and slaughtered and enslaved its inhabitants. Fearing that only the princess of Galaluna, Illana, can restore the hopes of the planet's people and have them rally against him, Modula sends countless monsters to ravage the planet where she's hiding out. It's made clear in the show that the buildings and cities his monsters destroy [[ConvenientlyEmptyBuildings are not conveniently empty]], and at one point Modula goes so far as to send a living bomb capable of wiping out an entire planet to earth all so he can kill one girl. While seemingly stoic on the outside, in actuality Modula is utterly AxeCrazy and [[HairTriggerTemper is willing to kill anyone, even his own minions, at the drop of a hat]]. Instances of this can be seen when he smiles as he snaps the neck of a resistance fighter and when he casually vaporizes a minion who had failed him without even getting up from his chair.

* Would you believe ''TotallySpies'' 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 PettingZooPeople, 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 EstablishingCharacterMoment?

* From the ''WesternAnimation/Ben10UltimateAlien'' series, we have Aggregor, who kidnaps aliens from different planets to zap their powers and use them as his own. [[spoiler: [[MoralEventHorizon What cements him as a Complete Monster is when he kills a peaceful turtle alien, all on SCREEN, and then turns its powers against its brethren before kidnapping the main one. And then he kills the plumber from Season 2 of AlienForce by stabbing him in the back when he found the prisoners]].]] And he managed to top himself, [[spoiler: learning of the Omnimatrix, he tries to force Ben into a form he wanted after a [[NoHoldsBarredBeatdown no-holds-barred shock down]] by ''stabbing'' him right in the Omnimatrix icon with his spear and ''twisting'' it. If not for the HeroicSacrifice of the jellyfish alien, Ben would have ''died'', since both Kevin and Gwen were down.]]
* ''WesternAnimation/CodenameKidsNextDoor'' has Grandfather from ''WesternAnimation/OperationZERO''. While the rest of the villains were [[LaughablyEvil too silly]] [[TooFunnyToBeEvil to be viewed]] [[HarmlessVillain as real threats]], although some did cross the MoralEventHorizon, such as [[CorruptCorporateExecutive Mr. Boss]] sending his employees' daughters to Pluto or [[LethalChef Grandma Stuffum]] force feeding children until they explode. They are still all either too LawfulStupid and/or StupidEvil to be taken seriously. The rest are either {{Card Carrying Villain}}s or, in Toilenator's case, a HarmlessVillain, and their [[FelonyMisdemeanor crimes aren't heinous at all]]. Even [[BigBad Father]] suffered from VillainDecay, but not [[BiggerBad Grandfather...]] He's an EvilOverlord 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 Senior Citizombies just because kids annoy him, and that's not even going into how much of an AbusiveParent he is. [[EvenEvilHasStandards Some of the other villains]] [[EvenEvilHasLovedOnes 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! He also states that Numbuh Zero is still his favorite son even though he was the one who defeated him in the first place. What's even worse is that children were shown working like slaves in his Industrial Age factories simply so he can have tapioca pudding, and to [[TruthInTelevision anyone who paid attention in history class]], that actually did happen and it was a FateWorseThanDeath.

** Van Kliess. [[EvilPlan 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.]] [[MoralEventHorizon 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 FiveManBand. Also implied to be behind the entire disaster. [[spoiler: Karma caught up to him, though. Twice. First he "dies" when he tries taking some super advanced nanites. Second, when he comes back, Rex pulls off a masterful BatmanGambit - have him rein the out of control nanites into line, then claim he's doing a FaceHeelTurn...then he ''cures'' Kliess, rendering him completely human and powerless.]] Very. Satisfying.

* ''RegularShow'' has a lot of villains, but few of them have motives truly evil enough to qualify. That is, until The Night Owl from the episode of the same name showed up. At first, he's just a JerkAss trying to become famous using a contest Mordecai, Rigby, Muscle Man, and High-Five Ghost are involved in and turning them against each other to lengthen it. Then he's pushed into this by [[spoiler:freezing the boys in liquid nitrogen for at least 2,000 years to keep the contest going [[SelfishEvil just to become famous]]. When they finally get free and he (now reduced to a disembodied head in a robot body) tries to stop them, outright saying that he doesn't give a darn about them and all he cares about is keeping them frozen in order to keep the contest going forever so he can remain a superstar. When they finally manage to travel back in time, it's revealed that this was his plan from the beginning. What's worse is, in a series where {{Eldritch Abomination}}s are MonstersOfTheWeek, a mere ''human'' manages to be one of the most evil villains in the entire show! He gets his in the end when the boys return to the present, destroying his billboard and car, thus foiling his plot before they could fall victim to it. To rub salt in the wound, Muscle Man gets a CrowningMomentOfAwesome by [[TalkToTheFist punching him out as he rants about how much his now destroyed plan cost him]].]]
* The last-revealed villain of ''[[ScoobyDooOnZombieIsland Zombie Island]]'', [[spoiler: Jacques]]. He seems like a nice guy at first, [[spoiler: a jolly old MrExposition]]. Don't let it fool you. The [[spoiler: cheerful ferryman]] thing? A lure to get people to trust him, so he can [[spoiler: take them to Moonscar Island]] where he and his accomplices [[spoiler: suck out their souls, turning them into zombies and gaining immortality]]. What's especially jarring is the contrast between him and the other 2 antagonists of the piece; specifically, they are [[spoiler: [[WoobieDestroyerOfWorlds Woobies Destroyers of Worlds]] who were cursed by accident, and now have to kill to live]]. This guy, though, [[spoiler: accepted the curse ''willingly'', it's implied to stave off his old age, and with full knowledge of the fact that he'd have to kill probably thousands]]. It seems [[DisproportionateRetribution rather unfair]], then, that [[spoiler: his accomplices share in [[NoImmortalInertia his punishment]]]].

* ''WesternAnimation/CodenameKidsNextDoor'' has Grandfather from ''WesternAnimation/OperationZERO''. While the rest of the villains were [[LaughablyEvil too silly]] [[TooFunnyToBeEvil to be viewed]] [[HarmlessVillain as real threats]], although some did cross the MoralEventHorizon, such as [[CorruptCorporateExecutive Mr. Boss]] sending his employees' daughters to Pluto or [[LethalChef Grandma Stuffum]] force feeding children until they explode.
