* Homer on ''WesternAnimation/TheSimpsons'' is one of Western Animation's most iconic examples.
* [[WesternAnimation/SpongeBobSquarePants [=SpongeBob=]]] is also one of Western Animation's most iconic examples. He exemplifies this trope too. Although in the [[{{Flanderization}} earlier seasons]] he was more of a naive CloudCuckoolander than an Idiot Hero.
* ''WesternAnimation/InspectorGadget''. He regularly bumbles around getting himself in trouble, being unable to put two and two together, and flat out being TooDumbToLive while his ten-year-old niece Penny and their dog solve every case for him and lead him to the bad guys, while he takes the credit for it.
* ''WesternAnimation/ActionLeagueNow''. Every character is TooDumbToLive. Even Thundergirl and Bill the Lab Guy have their moments.
* Launchpad [=McQuack=], of ''WesternAnimation/DuckTales'', who in many episodes, saves his friends, or even the whole world while remaining a certified idiot. He's even admitted it on more than one occasion. In the new comics, his search for a job since WesternAnimation/DarkwingDuck went [[TenMinuteRetirement out of the vigilante business]] is displayed by but a single panel from his interview with the [[WesternAnimation/ChipNDaleRescueRangers Rescue Rangers]]. No, Launchpad, you cannot, in fact, fly the Ranger Wing.
* Toby in ''WesternAnimation/GormitiTheLordsOfNatureReturn''. He's courageous, selfless and a {{Determinator}}, but also quite frivolous, impulsive and BookDumb, and has a tendency to pull pranks at the least appropriate moments, such as during a battle. Which becomes especially apparent when compared to his one-year-younger brother Nick.
** Ironically enough, Toby is the Lord of Water, and Water Gormiti -- especially Carrapax -- are usually depicted as calm and wise.
* [[Franchise/TransformersGeneration1 Hot Rod]] (until becoming Rodimus Prime), [[WesternAnimation/BeastWars Cheetor]] (pre-CharacterDevelopment), [[Anime/TransformersArmada Hot Shot]] (grows out of it), [[Anime/TransformersEnergon Ironhide]] (mostly grows out of it), [[Anime/TransformersCybertron Hot]] [[{{Retcon}} Shot]], [[WesternAnimation/TransformersAnimated Bumblebee]]. If they're the KidAppealCharacter in ''Franchise/{{Transformers}}'', they're most likely this.
* Mahad in ''WesternAnimation/{{Skyland}}''.
* Most people would be forgiven for thinking that ComicBook/TheFlash from ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'' fits this trope. (He fits a [[KidAppealCharacter bunch]] [[HandsomeLech of]] [[AllLovingHero others]] normally associated with this trope, too. His name is ''Wally'', for goodness sakes.) It came as something of a surprise for many fans when he turned out to be a ''[[SubvertedTrope forensic scientist]]'' in his day job. Plus there's the fact that he's [[CrouchingMoronHiddenBadass one of the most powerful members of the League]] under the goofiness and whenever you push him that little bit too far [[BewareTheNiceOnes things tend to get broken]].
** An example of this is faking his own death, on camera, while hooked up to a heart monitor. He speeds up his heartbeat so the monitor can't sense it and flatlines. Even Batman is impressed.
* Fry from ''WesternAnimation/{{Futurama}}'' is a {{Cloudcuckoolander}} on a good day. When it's ''not'' a good day... well...
** His 'lack of a Delta Brainwave' is the one thing that allows him to save all life in the universe from annihilation on more than one occasion.
-->'''Nibblonian:''' "There is but one being that can resist them. A child of destiny whose bizarre brain wave pattern makes him immune to the Brain Spawn attack. He is the hope of the universe. The fate of your world - perhaps all worlds - rests in his special mind."
-->'''Leela:''' "Now, when you say 'special'..."
* [[Comicbook/AchilleTalon Walter Melon]]. (Not ''that'' [[AquaTeenHungerForce Walter Melon]].)The ad for the show says "[[FearlessFool He knows no fear]]. [[InHarmsWay He knows no danger]]. [[CrouchingMoronHiddenBadass He knows... nothing!]]" And... he really doesn't. He's the ultimate mercenary: whenever a character needs to be replaced, he can replace them. And he gets the powers. (Whether he can USE them remains to be seen, he displays varying levels of ability every episode.) This being a comedy, he almost always relies on Dumb Luck.
* ''WesternAnimation/HongKongPhooey''
* Timmy Turner on ''WesternAnimation/TheFairlyOddparents''. He barely passes in school, and never, ''never'' learns to BeCarefulWhatYouWishFor, yet he saves the Earth and Fairy World multiple times. Granted, [[NiceJobBreakingItHero he causes many of the problems himself]].
** This happened so much that Jorgen, in the later seasons, has become [[GenreSavvy savvy]] enough to know that [[EndOfTheWorldAsWeKnowIt a typical world disaster]] is [[HereWeGoAgain just another day in the life of Timmy Turner]].
--->'''Jorgen''': (During the Fairy Baby special) There has been a disturbance in the fairy force! Someone was just about to wish for the '''B''' word! (poof in Timmy, Cosmo, and Wanda) Ah, Turner. [[SarcasmMode ''Biiiig'']] [[DeadpanSnarker surprise]].
--->'''Jorgen''': (During the second Christmas special) It's the day AFTER Christmas! Where is all this wishing coming from?! (Scanner show the magic is being pinpointed to Dimmsdale) Turner. ''[[TwitchyEye Of course.]]''
* Mikey Simon from ''WesternAnimation/KappaMikey'' is prone to being this trope.
* The titular character in ''WesternAnimation/EarthwormJim'' veers well into this territory more often than not; when he's not a {{Cloudcuckoolander}}.
* Palmer and Sasha from ''WesternAnimation/TitanMaximum'' are this with ''extreme'' emphasis on the idiot part.
** And the fact that Palmer is regarded as genuinely heroic despite being a gigantic moron who barely knows what he's doing is what motivates Gibbs into becoming evil.
* ''WesternAnimation/DudleyDoRight''
* ''WesternAnimation/GeorgeOfTheJungle'', in the eponymous television series. But Tom Slick (from the same show), a parody of the original Tom Swift, fits the trope even better. He only wins his races because his TrueCompanions aren't morons, and the villains make [[DickDastardlyStopsToCheat Dick Dastardly]] look rational.
-->'''Tom Slick''': Fear? I don't know the meaning of fear!
-->'''Granny''': He also doesn't know the meaning of 'broccoli'.
* The titular character on ''WesternAnimation/JimmyTwoShoes'' is dumb (or at least extremely naive), yet he remains the only person [[{{Satan}} Lucius]] can't break.
* ''WesternAnimation/{{Wakfu}}'' gives us Sadlygrove, resident knight-errant and infamous Iop-head. Also puts the emphasis on the ''idiot'' bit, at least until episode 22.
* Finn from ''WesternAnimation/AdventureTime'', by his very own admission with the page quote. Though he's more impulsive than outright dumb--he occasionally wins challenges through craft, for example ("The Limit," "It Came from the Nightosphere," "Memory of a Memory.")
** When asked why he's missing some teeth, WordOfGod said "he bites trees and rocks and stuff. He's stupid."
* Lion-O from the eighties ''WesternAnimation/ThunderCats'' series. A pretty justified case since he aged to physical maturity in a sleep capsule during the long journey to Third Earth. Lion-O is a kid stuck in an adult's body and is fairly naive at first. He eventually becomes a good leader over the course of the series.
* Lion-O from the ''WesternAnimation/ThunderCats2011'' series. The reboot centers on his coming of age travails. His {{Cloudcuckoolander}} beliefs alienate him from his own people, but endear him to the rest of Third Earth. He relies on the IndyPloy and the fortunate intervention of magic stones for many of his successes.
* Rudy Tabootie from ''WesternAnimation/ChalkZone'', although Snap, his trusty sidekick, is a more literal example.
* Rodney J. Squirrel from ''WesternAnimation/SquirrelBoy''.
* Tak in ''WesternAnimation/TakAndThePowerOfJuju''.
* Eric from ''WesternAnimation/{{Sidekick}}'', his friend Trevor also.
* Gerold Goode from ''WesternAnimation/TheGoodeFamily''.
* Coop of ''WesternAnimation/MegasXLR'' fits this to a T. The guy might know how to customize a giant robot, but no one ever said he knew how to pilot it. Or pilot it enough that it didn't level Jersey City more times than your typical ''Franchise/PowerRangers'' episode!
* One has to question the logic of these so called [[ChildProdigy "child geniuses"]] like [[WesternAnimation/DextersLaboratory Dexter]] or [[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]] or [[WesternAnimation/JohnnyTest the Test sisters]] who resort to mundane efforts of acquiring money such as lemonade sales or selling candy despite the fact that their technology would be worth a fortune, or could make far more valuable products. They probably have the technology to replicate whatever they could want to buy.
** Come ''FusionFall'', both Dexter and his rival, Mandark, have started their own technology businesses with now publicly known laboratories.
* Ben Tennyson from ''WesternAnimation/{{Ben 10}}'', though this case is heavily justified: after all, he is a ''10 year old'' kid using a highly advanced alien weapon he barely understands himself, and he's teamed up with a ridiculously precocious cousin (who is later revealed to have an innate talent for magic) and a BadassGrandpa; anyone in such a situation and with such allies would look dumb in comparison, unless you are a genius yourself. By the time of ''WesternAnimation/Ben10AlienForce'', he has grown out of his idiocy and is revealed to be much smarter than he seems, while his idiotics moments are more caused by his narcissistic tendencies following him becoming a LivingLegend.
** Interestingly, it was hinted in ''WesternAnimation/Ben10UltimateAlien'' that he actually was well-aware of the danger around him, even as a kid, and was just [[ObfuscatingStupidity acting like an idiot as a way to deal with the pressure]].
** Then comes ''WesternAnimation/Ben10Omniverse'', where a nearly legal Ben makes his 10-year-old self a genius.
* Bessie Higgenbottom from ''WesternAnimation/TheMightyB''.
* Adam Lyon and Jake Spidermonkey from ''WesternAnimation/MyGymPartnersAMonkey''.
* ''WesternAnimation/MrBogus'' occasionally falls into this territory DependingOnTheWriter.
* T.J. Detweiler from ''WesternAnimation/{{Recess}}'', though his unintelligence comes more out of laziness than actual stupidity. He's a genius when it comes up to coming up with plans, but he's ''extremely'' BookDumb.
* Wally and Gus from ''WesternAnimation/RocketMonkeys''. Gus is the more sensible of the two, but that's not saying much.
* Arguably deconstructed by The Pulverizer in ''WesternAnimation/TeenageMutantNinjaTurtles2012'', where his idiotic tendencies and [[IJustWantToBeBadass desperate desire to become special]] leads him to not only join the Foot Clan, but deliberately expose himself to Kraang mutagen, despite the efforts of the turtles to stop him. This turns him into the 2012 version of Mutagen Man... aka, an amorphous blob of corrosive goo with his organs floating around inside of him.
* Both ''WesternAnimation/RobotAndMonster'', Robot is the smarter of the two but he's GeniusDitz.
* Cat and Dog from ''WesternAnimation/CatDog'', with Dog definitely the worse of the duo.
* Flapjack from ''WesternAnimation/TheMarvelousMisadventuresOfFlapjack. Especially in "I'm a Believer".
* ''WesternAnimation/ScaredySquirrel''
* Maggie Pesky from ''WesterAnimation/TheBuzzOnMaggie''.
* Brain Newport from ''WesternAnimation/ThisJustIn''.
