History AxCrazy / WesternAnimation

* ''WesternAnimation/Grim Adcentures of Billy and Mandy'' has [[Enfante Terrible|Mandy]], a pretty [[Sadist|sadistic]] and rather [[The Napoleon|abusive and short-statured]] girl.

** Lemongrab's first incarnation, Lemongrab 1, was a violent cannibalistic madman. However, much of his {{AxCrazy}}ness is very downplayed after his redemption as Lemongrab 3.
** Simon Petrikov as the Ice King. He was homicidal, explosive and mentally unstable.
** Flame Princess. Whether you think she is good or evil, it's clear she enjoys burning things a little too much, made abundantly clear after going on a rampage in "Vault of Bones".

** Nicole Watterson. Several episodes have shown that she can become dangerously insane and ''even'' homicidal.

* ''WesternAnimation/{{Archer}}'' gives us Cheryl (who sometimes answers to "Carol", "Carina", "Cristal", and possibly a host of other names). She's a compulsive pyromaniac, gets off on suffering physical and emotional violence, once spent 6 months believing that she was a werewolf, and is more often than not stoned out of her skull on either rubber cement or LSD-laced Gummi Bears (or both.) Luckily for everyone else at the company, she seems to get off more on her own pain than anyone else's. There's also Barry, who appears to have two personalities and has murdered several people, including the entire staff of a space station.
* Around the end of ''WesternAnimation/AvatarTheLastAirbender'' [[spoiler:Azula definitely qualifies, having absolutely lost it after Mai and Ty Lee betrayed her. She has an absolute [[VillainousBreakdown breakdown]] before her final battle with Zuko and Katara]]. Ozai also counts as this as while he’s usually very self controlled, if sadistic and short tempered, his glee at [[spoiler: torching the Earth Kingdom in the climax]] shows just how much of a violent, sociopathic madman he is just inches beneath the surface.
* Rampage of ''WesternAnimation/BeastWars'' flips between this and the BloodKnight. Originally, he attempted to kill anything in sight, no matter whether they were Maximals or Predacons. In fact the only reason he joined the Predacons after his first appearance was because Megatron held his life in his hands by removing his spark and keeping it for torture/incentive for Rampage to serve him, otherwise he'd probably try to kill them all. The fact he's one of the most heavily armed Transformers in the series doesn't help. He even mentions being a cannibal!
** Then there's Inferno, Megatron's PyroManiac [[TheDragon Dragon]]. To wit:

* Kevin 11 in the original ''WesternAnimation/Ben10'' is an EnfanteTerrible who gets off on inflicting violence and pain on others. To a lesser extent, there's also [[BigBad Vilgax]], who always keeps his composure but also clearly derives pleasure from causing death and destruction.
* ''WesternAnimation/TheBoondocks'': [[CreepyChild Lamilton]] [[EnfantTerrible Taeshawn]]. His extreme sociopathy actually scares [[{{Delinquent}} Riley Freeman]], which should say a lot.
** All three members of [[TerribleTrio the Hateocracy,]] as well as [[GrumpyOldman Colonel H. Stinkmeaner]] himself.

** Katz, as expected from a psychopathic SerialKiller with a sadistic streak. His first appearance had him ''feeding the residents of his hotel'' to spiders, and to remind you this is his ''first appearance''.

* WesternAnimation/DarkwingDuck's foe [[EvilTwin Negaduck]] is about as close to [[BadButt a kid-safe]] Ax Crazy as you can get, especially considering it's a Disney show. Negaduck's favored weapon, for example, was a chainsaw, and he takes great delight in attempting to blast cute fuzzy bunnies with a shotgun. This may or may not be a case of being a product of his environment.
** Negaverse Launchpad? Happy with firing a bazooka at cute little girls. The Muddlefoot family? Tank's okay as a non-evil twin, but Herb, Binky, and Honker were shown with a row of severed duck heads on a pole in their yard. With their beaks sewn shut.
* Disney's classic ''Mickey and the Beanstalk'' features WesternAnimation/DonaldDuck near the start, almost delusional from hunger. It's one of his most dynamic moments; some find it hilarious, others quite a bit creepy. [[https://www.youtube.com/watch?v=KqEVYbPw9lI See it here.]]

** Vicky. She's a crazed psychopath who will go above and beyond to torture kids For the Evulz.
** Wanda. Specially when she is mad, demonstrates the sanity that she has, or rather, lacking. Not to mention it also demonstrates extremely [[{{Sadist}} sadistic tendencies]]. Specially in the episode "A Bad Case Of Diary-Uh!" when she finds out that Vicky called her a "fat pink squirrel".

** Meg too, out of a desperation for love and affection, which is semi-justified and understandable since she seldom receives love and affection.

** Stewie's evil clone. He is ''much'' more mentally unstable and sadistic than the original. His actions are probably some of the most violent and graphic scenes in the history of WesternAnimation and make regular Stewie's crimes look like ComicStrip/{{Dennis the Menace|US}}.
** And we also have Jeff Fecalman, the abusive boyfriend of the Quagmire's sister, who beats her for the smallest things, also willing to kill in cold blood.

** An even much straighter example is Mac's sociopathic older brother Terrence, who takes sadistic pleasure in making Mac's life a living hell.
* Wendell from ''WesternAnimation/FriskyDingo'' is very definitely this. He randomly kills people for no conceivable reason, offers to abort a baby with a machete, then when said baby is born and revealed as a gigantic ant larvae monster, he rides it to the location of a doomsday device to destroy the earth... just BECAUSE.
** With his pants off no less, commenting throughout on how wrong it is but how he's going to continue to do it.

** Roberto, the dangerously insane, psychopathic robot whose literal function is to stab others (there's a reason he resembles a tombstone). His many insane acts includes robbing the same bank three times in a row, killing other robots to provide a disguise for himself, and "practicin' my stabbin"! Not that it's truly his fault; whatever idiot built him ''programmed'' him to be a sociopath.

** Then there's Robot Santa.

* Disney [[UpToEleven one-upped itself]] in ''WesternAnimation/{{Gargoyles}}'', with Demona. During the City of Stone arc, she manages to turn all the humans in UsefulNotes/NewYorkCity [[TakenForGranite to stone]], and then is seen roaming the streets, casually destroying humans-turned-to-stone with a huge mace.

* Cobra Commander in ''WesternAnimation/GIJoeResolute''.

** There's also Dipper's comment from Weirdmageddon 2 on some rather questionable glitter rain: "Knowing Bill, it's probably just bones, or ground up babies, or something."

* Curly from ''WesternAnimation/HeyArnold'' is hinted to being this at times. Helga on occasion too, specifically in "Helga's Parrot."

* Itchy from ''WesternAnimation/TheItchyAndScratchyShow''. Itchy is a mixture of Ax Crazy and sociopath, sadistically killing Scratchy in various painful ways, and with different instruments: chainsaws, axes, guns, etc.. And the worst is that it only does it for fun.
* The Monkey King from ''WesternAnimation/JackieChanAdventures''. At first, he seems like a prankster, but before long he's going after Jackie and Jade with an actual axe.
* Heloise on ''WesternAnimation/JimmyTwoShoes'' is a malicious EnfantTerrible who loves spreading misery as much as her boss. The only person she doesn't want to hurt is [[MoralityPet Jimmy]], and he's not completely safe from her wrath. Also, Saffi gets this way around statues [[CloudCuckoolander (although she already is pretty loony when at peace)]].

** Dale Gribble is a bit of a mild example from this series. Dale is a major conspiracy theorist who thinks that everything and everyone is out to get him. He is also the most prone to threatening to kill others including his own friends and has been described as "mentally unstable" numerous times throughout the series. It doesn't help he's a professional exterminator and carries more guns than a regular person should need.
** Mad Dog is basically Dale when he loses any small bit of sanity he has left. This dude is more prone to kill others when pushed to far (and that's a VERY thin line to cross) and even holds other people hostage when he doesn't get this way. You know you're crazy when it's ''[[DirtyCoward Dale]]'' that has to be the one to save you.

** However, the character that tops ALL of these characters above is Trip Larson. This guy has a very nightmarish desire to recreate his perfect family by forcing Luanne to dress up as the Pork Products girl. What really tops off his insanity is during the climax of his only episode, he actually tried to ''kill'' Luanne by forcing himself and her to be [[TakingYouWithMe pork products together]]. Before he is shocked back to sanity, he laughs pretty mechanically before accepting his fate. Unfortunately, as soon he is able to think clearly, he was ''brutally'' killed (off-screen thank goodness).
* Robex the Cut-Throat from ''WesternAnimation/OrsonAndOlivia''.
* Rico from ''WesternAnimation/ThePenguinsOfMadagascar''. Lampshaded by Skipper.

* Benson from ''WesternAnimation/RegularShow'' became this at times. His HairTriggerTemper is so extreme that he reaches many times a psychotic behavior.

* Rick from WesternAnimation/RickAndMorty. He has been shown on multiple occasions to go absolutely berserk and overboard upon provocation, including ripping off the equivalent of a robot's testicles and shoving it down said robot's throat when tipped off to the police, engaging in cross-dimensional crossfire with himself when he thinks that other versions of him are trying to kill him, literally going ax-crazy and violently murdering various clones of himself (including a child and an infant), exploding an entire alien colonisation for putting him in a simulation and creating accurate genitalia for his grandson Morty, destroying an entire universe in order to spite its creator, programming his space-car to torture and murder in cruel and horrific ways or manipulate/coerce people into staying away from it when advised and committing countless other atrocities.

** Even his grandson Morty has show this when he gets pushed and loses his sense of morality he becomes a homicidal lunatic.
* ''WesternAnimation/RockosModernLife'': Rocko and Heffer are on a bus tour of Paris with a bus driver who is determined to keep his passengers on the bus ''at all costs'', so much so that he chases them around the city after they escape.

** [[TheHeavy Scaramouche the Merciless]] is a sadistic [[RoboticPsychopath Psychopath]] [[PsychoForHire For Hire]] who slaughtered a village filled with innocent men, women, and children. When Jack confronts him, he reveals he did this days ago, and has been casually waiting for him (Jack) to show up.

** Sideshow Bob started to qualify for this when his attempts to kill Bart included trying to have him ''cremated alive'' and when he visibly ''removed his cell mate's face and cut off his own''. He also ties up Bart while singing casually about wanting to [[EyeScream gouge out Bart's eyes]]. And then there's the Treehouse of Horror XXVI segment "Wanted: Dead, Then Alive" which has several moments that are genuinely disturbing. First, Sideshow Bob finally kills Bart. And it's not an over the top, comically ridiculous death, but fairly realistic. Bart gets harpooned through the heart, and since that doesn't immediately do the trick, Bob RETRACTS the harpoon and RIPS HIS HEART OUT. He then tears out Bart's large intestine and dances around with it and singing about how happy he is that Bart's dead before using it to tie his corpse to himself like a harness. It's also then revealed that Bob has kept Bart's corpse as it starts to decompose, eventually stuffing him in a compartment in the wall, even talking to him and playing golf with his body like he was alive. To make it worse, Bob revives Bart and then kills him again in various other ways—including mauling him by a lion and bludgeoning him with a sledgehammer while he's still conscious.

-->'''Crazy Dude:''' I am [[NamesToRunAwayFromReallyFast the Angel of Death]]. [[TheEndIsNear The time of purification is at hand]].
** Homer himself went on a murderous rampage in a Treehouse of Horror episode when the cable wasn't working and when they ran out of beer in a WholePlotReference to ''Film/TheShining''.

* Replicon, the most sadistic, trigger happy villain in ''WesternAnimation/SkysurferStrikeForce''.

** Eric Cartman. He [[spoiler:kills Scott Tenorman's parents and feeds them to him in the form of chili. Why? [[DisproportionateRetribution Because Scott scammed him out of $16.]]]] On his page on the official [[http://southpark.wikia.com/wiki/Eric_Cartman#Mental_Health South Park wiki]], it has a detailed paragraph on his mental health. Apparently, Eric Cartman shows signs of sadism, Schizophrenia, identity issues, gender confusion, psychosis, psychopathic nature, narcissism, and [[DepartmentOfRedundancyDepartment possibly even insanity]].
** In addition to Cartman, there is a good cast of violent, crazy characters: Saddam Hussein, the Earth Day Brainwashing Society, the Woodland Critters and MickeyMouse. But '''Mel Gibson''' (in the canon of the series of course) is the best one.
** Sheila Broflovski, who was already crazy to begin with, was upgraded to this in ''WesternAnimation/SouthParkBiggerLongerAndUncut''

** "Hell On Earth 2006" shows the "antics" of Ted Bundy, John Wayne Gacy and Jeffery Dahmer, RealLife [[SerialKiller serial killers]]. Said "antics," are called so because they become a parody of sorts of Film/TheThreeStooges after their initial introduction.
** The obviously insane Hat [=McCullough=] from "Free Hat", though his defenders claim he killed those twenty-three babies in self-defense.

** Mr. Krabs is often a step away from being dangerously insane because of his extreme obsession with the money. "Clams", for instance, has [=SpongeBob=] and Squidward rightly disturbed from seeing him go crazy over Ol' Bluelips stealing his millionth dollar. This is even more prominent after the movie.

** Plankton himself became one in [[WesternAnimation/TheSpongeBobSquarePantsMovie the first movie]]. He is much more deranged, sadistic, depraved and homicidal than usual.

* [[Comicbook/TeenageMutantNinjaTurtlesMirage The Mirage Turtles]] in {{the|Movie}} WesternAnimation/{{Teenage Mutant Ninja Turtles|2003}} [[TheMovie TV movie]] ''WesternAnimation/TurtlesForever''.

* ''WesternAnimation/{{Thundercats 2011}}'' has Kaynar, a {{giggling|Villain}} PsychoForHire recruited as one of BigBad Mumm-Ra's new [[FourStarBadass generals]]... when they bust him out of ''prison.'' His EstablishingCharacterMoment sees him strapped to a gurney and heavily restrained just to be moved to solitary confinement, which he earned after killing [[SerialKiller eleven inmates]]. He's pretty sanguine about his punishment:

** Mal, evil personality of Mike, of the second generation. He just loves inflicting pain on others.
** Scarlet true self is this. To the extent where she tried to [[spoiler: blow up the island which would have killed everyone]].

* [[BigBad Galvatron]] from Franchise/TheTransformers was so violently nuts, ''the AlwaysChaoticEvil Decepticons actually took him into therapy''. Naturally, he blew up the [[PlanetOfHats therapy planet]].

* From ''WesternAnimation/TheVentureBrothers'', Tim-Tom and Kevin, Dr. Girlfriend/Mrs Monarch's aptly named Murderous Moppets, who [[KnifeNut like knives]] a little too much.

--> '''Galvatron''': [[CrushKillDestroy Kill! Smash! Destroy!]]

* Heloise on ''WesternAnimation/JimmyTwoShoes'' is a malicious EnfantTerrible who loves spreading misery as much as her boss. The only person she doesn't want to hurt is [[MoralityPet Jimmy]], and he's not completely safe from her wrath. Also, Saffi gets this way around statues.

** Lemongrab's previous incarnation, Lemongrab 1, was a violent madman and had even committed cannibalism. However, much of his {{AxCrazy}}ness is very downplayed after his redemption as Lemongrab 3.

** Then we have a lot of unhinged psychos such as Le Quack, Benton Tarentella, the Great Fusilli, Schwick, Basil and Doctor Gerbil.

* [[BigBad Galvatron]] from Franchise/TransformersGeneration1 was so violently nuts, ''the AlwaysChaoticEvil Decepticons actually took him into therapy''. Naturally, he blew up the [[PlanetOfHats therapy planet]].

** We also have to Stewie's evil clone. He is much more mentally unstable and sadistic than the original, making a lot of atrocities ForTheEvulz.

* Robex the Cut-Throat from ''WesternAnimation/OrsonAndOOlivia''.

* The Monkey King from ''WesternAnimation/JackieChanAdventures''. At first, he seems like a CrazyAwesome prankster, but before long he's going after Jackie and Jade with an actual axe.
* Heloise on ''WesternAnimation/JimmyTwoShoes'' is a malicious EnfantTerrible who loves spreading misery as much as her boss. The only person she doesn't want to hurt is [[MoralityPet Jimmy]], and he's not completely safe from her wrath. Also, [[CrazyAwesome Saffi]] gets this way around statues.

** Simon Petrikov as the Ice King. He's homicidal, explosive and mentally unstable.

** Lemongrab as his previous incarnation (Lemongrab 1) was impulsive and violent in the most frightening way possible when he is in a bad mood and had even committed cannibalism. However, much of his AxCrazyness is very downplayed after his redemption.

** The Earl of Lemongrab is the living embodiment of this trope. He is impulsive, psychotic, irrational and violent in the most frightening way possible when he is in a bad mood, [[spoiler:and has even committed cannibalism.]]
** The Ice King is mentally unstable and likes kidnapping people. However, he appears to draw the line at using lethal force on sentient beings, even though it's repeatedly shown that he's more than capable of it.

** The Earl of Lemongrab is the '''living''' embodiment of this trope. He is impulsive, psychotic, irrational and violent in the most frightening way possible when he is in a bad mood, [[spoiler:and has even committed cannibalism.]]

** '''Roger''', full stop.

** Negaverse Launchpad? Happy with firing a bazooka at cute little girls. The Muddlefoot family? Tank's OK as a non-evil twin, but Herb, Binky, and Honker were shown with a row of severed duck heads on a pole in their yard. With their beaks sewn shut. Fun for the whole family, that Disney!

* ''WesternAnimation/EdEddNEddy'': [[spoiler:Eddy's Brother]] from ''WesternAnimation/EdEddNEddysBigPictureShow''. A twisted ChildHater who [[{{sadist}} loves]] tormenting kids both physically and mentally. He also started to physically assault Eddy in an extremely brutal way.

* Disney [[UpToEleven one-upped itself]] in ''WesternAnimation/{{Gargoyles}}'', with Demona. During the City of Stone arc, she manages to turn all the humans in UsefulNotes/NewYorkCity [[TakenForGranite to stone]], and then is seen roaming the streets, casually destroying humans-turned-to-stone with a huge mace. This one didn't so much bypass the radar as tore the radar a new a-hole. And since it's Disney, ''nobody called them on it''.

** Gaz also counts given she once happily used a device that could destroy the world and was DISSAPOINTED when it failed to work. And then there's what she did to Iggins...poor Iggins. He really should have listened to Gaz's warnings.

* Curly from ''WesternAnimation/HeyArnold'' is hinted to being this at times.

* Eva and Izzy from ''WesternAnimation/TotalDramaIsland''. Izzy does appear as a lovable goofball but she shows signs of this.

** And let's not forget about how he rearranged the face of someone on a whim, [[Trope/AndIMustScream removing their mouth.]]

* Around the end of ''WesternAnimation/AvatarTheLastAirbender'' [[spoiler:Azula definitely qualifies, having absolutely lost it after Mai and Ty Lee betrayed her. She has an absolute [[VillainousBreakdown breakdown]] before her final battle with Zuko and Katara]]. Ozai also counts as this as while he’s usually very self controlled, if sadistic and short tempered, his manic glee at [[spoiler: torching the Earth Kingdom in the climax]] shows just how much of a violent, sociopathic madman he is just inches beneath the surface.

* ''WesternAnimation/DanVs'': Dan himself, as well as many other characters he vows revenge on.
