* ''WseternAnimation/FamilyGuy'': Peter Griffin is so dangerously stupid that he even burned down a children's hospital, by accident!

** ''Film/GodzillaVsKong'': [[Characters/MonsterVerseHumans Apex Cybernetics]] are so blinded by hubris that [[spoiler:they legitimately thought they'd have no problem using ''[[OmnicidalManiac King Ghidorah]]'s'' remains' lingering telepathic consciousness as the damned ''nervous system'' of Mechagodzilla, a HumongousMecha which Apex deesigned specifically to be unstoppable even to Titans. This leads to Ghidorah's consciousness remnants hijacking the Mecha the moment it gains a lasting power supply, [[TooDumbToLive slaughtering Apex]], and then going on to level half of Hong Kong with the implication that Mechagodzilla would pick right up where Ghidorah left off with bringing an extinction event if it won]].

* This trope is the entirety of Team Magma and Team Aqua's plans in ''VideoGame/PokemonRubyAndSapphire''. At no moment the game ever denies the fact their plans make no sense (and that they are going to bring anything but the supposedly beneficial effects their plans are meant to bring), but the fact these teams have the resources to pull off those plans are what makes them threats in the first place.

* WesternAnimation/InspectorGadget causes a great deal of harm to his superior Chief Quimby by always tossing the [[ThisPageWillSelfDestruct exploding message]] back at him. There are also times he somehow takes out Claw's minions by his own stupidity when his gadgets get out of hand. Somehow, [[WesternAnimation/GadgetAndTheGadgetinis a promotion to Lieutenant]] makes him ''even worse.''
* ''WesternAnimation/InvaderZim'', due to being very ChaoticStupid, such as accelerating the expansion of an explosion that had slowed down due to being in a time chamber. Even ''[[{{Cloudcuckoolander}} GIR]]'' points out how stupid that action was.
--> '''GIR''': But if it goes fast, won't it get all bad?

* In ''WesternAnimation/JackieChanAdventures'', many episodes start when Jade causes trouble when toying with magic. She even accidentally shrank Jackie. And blew herself up... and duplicated herself... and knocked out Uncle one time. It's no wonder her older self recruits Uncle to produce the spells on her behalf. And once nearly ascended to the level of Demon...
* The titular character of ''WesternAnimation/JohnnyBravo'' has frequently endangered people's lives because of his stupidity, with the episode "Bootman" even having his idiocy resulting in the apparent deaths of the superhero the Green Swoosh and the rest of the Astounding League of Super-People.
* In ''WesternAnimation/{{Metalocalypse}}'', all the members of Dethklok are this. Every time they put on a show, it's likely to result in the violent deaths of their fans and other innocent victims, as the group tends to leave a trail of death and destruction anywhere they travel. Dethklok even requires fans who attend concerts to sign "pain waivers" that absolve the band of legal liability for these occurrences.

* ''WesternAnimation/MyLittlePonyFriendshipIsMagic''

* Dr. Heinz Doofenshmirtz of ''WesternAnimation/PhineasAndFerb.'' In ''WesternAnimation/MiloMurphysLaw'', his "condition" is distinguished from [[TheJinx the title character's]] as follows: Milo [[WeirdnessMagnet causes chaos by his mere presence]], whereas Doofenshmirtz causes it with bad decisions.

** The Mayor is far too incompetent for a crime-stricken place like Townsville, and can't do anything more useful than calling the girls. And whenever he does something else, it's stupid and troublesome. In one episode, he even sold his town to Princess for candy. In another, the Mayor goes drunk with power overzealously trying to fight crime, in minutes going from effective to DisproportionateRetribution to punishing imagined crimes to finally even outright destroying Townsville in an attempt to save it.

* In ''WesternAnimation/TeenageMutantNinjaTurtles2012'' Michelangelo has been gradually becoming this. He often makes the mistake of goading monsters and mutation freaks which doesn't end well, and him screwing off near or with mutagen has resulted in several characters getting exposed to it, even himself at one point. And he still doesn't learn.

* In ''WesternAnimation/JackieChanAdventures'', many episodes start when Jade causes trouble when toying with magic. She even accidentally shrank Jackie!
** And blew herself up... and duplicated herself... and knocked out Uncle one time. It's no wonder her older self recruits Uncle to produce the spells on her behalf.
*** And once nearly ascended to the level of Demon... (Though it saved the world in retrospect.)

* Lumpy from ''WebAnimation/HappyTreeFriends''. He has a higher kill count than Flippy, who has an AxCrazy SuperPoweredEvilSide!

** Goten and Trunks aren't that bad on their own, but when they fuse into [[SmugSuper Gotenks]], all bets are off. Thanks to the rash decisions he makes in an attempt to make himself look cool, Gotenks unwittingly caused himself and Piccolo to get trapped in the Hyperbolic Time Chamber, Super Buu to eat his friends and loved ones, and allowed Super Buu to eventually absorb his power and give him an edge against Gohan. For [[SurprisinglyRealisticOutcome this reason]], in ''[[Anime/DragonBallSuper Super]]'', Goku and Vegeta automatically decide that Gotenks is too unpredictable, thickheaded, and irresponsible to be trusted with anything to do with the [[NotJustATournament Tournament of Power]] and refuse to let him or his components participate.
