History AxCrazy / WesternAnimation

* Barry Robinson from ''AmericanDad'', when is not medicated.

* Lemongrab from ''AdventureTime'', especially when he's pissed.

* The Crazy Farmer / Janitor from ''BeavisAndButthead''. Mainly in the episode "Cow Tipping".

** George Liquor, the Fire Chief, Haggis [=McHaggis=], and Jerry The Bellybutton Elf as well.

* Eric Cartman on ''WesternAnimation/SouthPark''. 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 antagonists which undoubtedly belong to this trope: Saddam Hussein, The Woodland Critters and Mickey Mouse. But '''Mel Gibson''' (in the canon of the series of course) is the best one.
** Randy Marsh, especially in "T.M.I." and "A Nightmare on Facetime".

* Katz from ''WesternAnimation/CourageTheCowardlyDog'' is a genuine psychopath.

*

* The eponymous character of ''WesternAnimation/InvaderZim'': Ax Crazy, PsychoForHire, and MadScientist, all rolled into one. Which ''would'' make him a {{Magnificent|Bastard}} {{Badass}}, if he wasn't also [[MikeNelsonDestroyerOfWorlds hyper-incompetent]], [[LordErrorProne incredibly narcissistic]], and a frequent [[TheChewToy Chew Toy]], as well.

* ''WesternAnimation/{{Futurama}} ''features 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"!

* In ''WesternAnimation/{{Daria}}'', Ms. Li is this in "Fizz Ed".

* ''AdventureTime'' has two: Ice King and Lemongrab.

* Flippy from ''WebAnimation/HappyTreeFriends'', if reminded of the W.A.R. (and nearly ''everything'' reminds him of it). Over the course of the show, he has brutally murdered around 53 innocent characters in a variety of ways that are as [[CruelAndUnusualDeath creative as they]] [[{Gorn} are gruesome]].

* Flippy from ''WebAnimation/HappyTreeFriends''. Over the course of the show, he has brutally murdered around 53 innocent characters in a variety of ways that are as creative as they are gruesome.

* Lemongrab from ''AdventureTime''. But also he's a HairTriggerTemper.
** The Ice King and The Lich as well.

** Stevearino. And in fact, at point for being a CompleteMonster.
