Top 10 Dumbest Cartoon Characters

The Top Ten
1 Patrick Star - Spongebob Squarepants Patrick Star is a fictional character in the American animated television series SpongeBob SquarePants, and he is one of the 10 main characters in the show. He is voiced by actor Bill Fagerbakke, who also voices numerous other characters on the show. Created and designed by marine biologist and cartoonist Stephen Hillenburg, the series creator, Patrick first appeared on television in the show's pilot episode "Help Wanted" on May 1, 1999. more.

There's a fine line between likeable dumb to atrociously dumb, and Patrick is nowhere near likeable sine he said and I quote " you can't expect my normal brand of stupidity I like to mix it up keep you own your toes" so he's aware that's he's stupid but he likes to ruin his friends lives. For more details on why Patrick is one of the worst check out mr enters top 11 Patrick's a prick episodes and see why patrick deserves worst

In the beginning of the show Patrick's stupidity is what made him charming and we got a good amount of classic lines from him, but since season five, it's really gone down hill. Patrick now is pretty one dimensional and there have been episodes where they use his stupidity to make him rude, get Gary almost killed (not kidding) and really unlikable.

Patrick is dumb... probably? I think SpongeBob is dumber. He's just playing dumb. He's probably just a little crazy and greedy (probably? ) If he's just pretending to be dumb to friends with SpongeBob, I think that's kinda nice... If he's dumb for real, I still like him. If he's dumb doesn't mean we hate him

He was good in the first 4 seasons and the movie but became a jerk and "not actually stupid" in the next seasons( though In some later season 9 and season 10 episodes he was good). Just say one of the many lines Patrick said before the movie and then name one one memorable quote after the movie

2 Peter Griffin - Family Guy Peter Griffin is the main protagonist and titular character of the American animated sitcom Family Guy.

Employer: So, Peter, where do you see yourself in five years?

Peter: (thinking) Don't say, "Doing your wife." Don't say, "Doing your wife." Don't say, "Doing your wife."

Peter: Doing your...(sees the employer's family picture) son?

Over time, he's gotten annoyingly and unlikably stupid, such as not listening to Brian when he warned him about consuming Kerosene (resulting him in having to have a Kidney Transplant), or thinking having a mustache makes him Italian. THAT'S RACIST!

Employer: So, Peter, where do you see yourself in five years?
Peter: (thinking) Don't say, "Doing your wife." Don't say, "Doing your wife." Don't say, "Doing your wife."
Peter: Doing your... (sees the employer's family picture) son?

I don't watch family guy, but Susie did a show and tell on a doll and he was like, OH MY GOSH WHO THE HECK CARES! This is a classroom, and show and tell! There are some girls around here, you know! Am I right?

3 Homer Simpson - The Simpsons Homer Jay Simpson is the main protagonist of the American animated television series The Simpsons as the patriarch of the eponymous family.

Homer Simpson is probably the smartest out of all characters in this list. Sure, he's dumb at times, but has done really good things such as saving Springfield and saving his brother from getting seriously injured/killed. Simpson is a great hero no matter how is intelligence is. He should be #1 instead of Patrick Star because I don't care about SpongeBob anymore and he now acts annoyingly dumb, and Peter Griffin too because he is a pervert (too much to explain).

for once I want someone to say to me "Sir" without the "your making a scene"-Homer Simpson

"D'oh!" - What has he done this time! :) OMG Homer is so dumb, but that is what makes him so hilarious! Here's one of his quotes:
"Volunteering is for suckers. Did you know that people who volunteer don't even get payed for what they do?!"

"Ah I have 3 kids and no money. Why can't I have no kids and 3 money? " -Homer Simpson

4 Ed - Ed, Edd And Eddy Ed is one of the three protagonists in the Canadian-American animated comedy television series Ed, Edd n Eddy. He is the strongest and the least intelligent member of the Eds.

I choose Ed over Patrick simply because Ed, in my opinion, is more likable than Patrick, despite them basically holding the same idiocy. Now these days, Patrick is so dumb that it's not funny anymore, but rather more frustrating and annoying, while Ed still managed to be funny while being stupid, never once annoying me. Also, Patrick may have his touching dumb moments, but there are also many times where he is just a jerk (Valentine's episode, When he was crowned King), but Ed always cared for Edd and Eddy... in his own way Also... GO NERDS! He is a comic/video game lover! GO ED!

One of the best cartoon characters ever! He may be dumb, but he is a loyal friend and a good guy!

Dumbest, but funniest cartoon character I've ever seen

Ed might be dumb but he is a good character and my favorite in ed edd n eddy becuse he is strong and hunky

5 Ralph Wiggum - The Simpsons Ralph Wiggum is a side character in The Simpsons. He is the son of Chief Wiggum. Ralph is not very smart at all. He is voiced by Nancy Cartwright. Some episodes such as I Love Lisa and This Little Wiggy have him as a major character.

You know you're stupid when you one had a trope for incredibly stupid characters named after you. has a trope called "The Ditz" for characters who are dumb, but for a short while, they also had a trope called "The Ralph Wiggum" for characters who take stupid to a whole new level. To qualify for that trope, you had sink bellow the average level of stupid, and only the dumbest of the dumb were put on this page (ex. Patrick Star). The fact that the trope was named after Ralph Wiggum and not Patrick Star or any of the other characters on this page is a testament to Ralph's extreme stupidity.

"I drink blue juice from under the sink"
"when I grow up, I want to be a catapillar"
"When I grow up, I want to be a triangle"

Homer is only above because he's more popular! At least he can speak actual sentences and say things appropriate to the subject. (Usually)

Bart Simpson goes by Ralph skateboarding naked. "I like men now" dumbest character ever.

6 Billy - The Grim Adventures Of Billy And Mandy

I hate that character from Billy and Mandy! He should be on the number one list because he's much more stupid than Patrick Star! Plus his nose is so huge he can snort the whole cocaine up his nose!

I grew up with Bill and Mandy and Billy ALWAYS MADE ME LAUGH!... Granted Mandy was always and still is my favorite but Billy really knew how make me smile... DESTROY US ALL!

Billy is the stupidest, dumbest, and most idiotic character on the fabe of the earth. He uses the Grim Reapers hand to pick his nose. Wow

Remember stuck in the wringer and pet sitter pat

7 Cosmo - The Fairly Odd Parents Cosmo is Timmy fairy godfather. He's Wanda's husband and Poof's dad. Cosmo is very immature and stupid, but also very charming and a loving father, godfather and husband.

WHAT! He should be at the top. He doesn't even have a brain! He has jelly in his head! He is the definition of IDIOT! He gets everyone in trouble.

Cosmo has to be the dumbest cartoon character ever existed... But that's what makes his funny.

I'm Even Watching The Fairly OddParents right Now! Cosmo is dumb, he's Funny

Yes, he's dumb, but he's still funny! Well, not that much in the recent seasons.

8 Lindsay - Total Drama Island

I don't know who this is but I read the comments and those are some of the dumbest things that I ever heard.

Lindsay is a dumb character, it's just in a funny way, which is why she is my number one. And Lindsay x Tyler is a great couple!

"I love musicals, especially the ones with singing and dancing"

This is not the right friend for Beth.

9 Richard Watterson - The Amazing World of Gumball Richard Watterson is the father of Gumball, Darwin, and Anais in the animated series The Amazing World of Gumball.

Richard is the only character who can even get close to Homer Simpson and Patrick Star in dumbness. Here is a quote from this brainless rabbit.
"Sorry, I've got a medical condition... called laziness..."

This guy is definition of dumb!
The amazing world of gumball is my favorite show. Richard makes this show funny!
Plus he is married to a good looking lady!
Laugh out loud love their relationship!

This guy is so dumb. he thinks his atm card was sorta lie a magic card where you dial the magic numbers for money to come. he's no better than homer

Every time I see this character I want to erase him from existence, he makes me cringe with anger and loathing.

10 Leni Loud - The Loud House Leni Loud is a fictional character from The Loud House the second oldest of the Loud Family a bit of a ditz, forgetful and absent minded despite this she's a kindhearted person, a skilled fashion designer and is always willing to help others in need, she shares a room with Lori the oldest and suffers from a case of arachnophobia as seen in the episode "Along Came a Sister".

She can be smart when it comes to fashion and she is creative. She not as dumb as Patrick and is always willing to help and she is the nicest character on the Loud House like Luan.

She may not be bright, but she does care about her family (like in the episode, "One Flu Over the Loud House", when she wanted to help her sick siblings).

She is probably my favorite. She isn't really sharp but that's what makes her funny. To be honset, if I were to trust either Leni or Patrick, it's no contest.

The dumb blonde character the best dumb blonde Like Patrick from Spongebob and Mikey from Bunsen is a beast so yeah Leni is the dumb blonde.

The Contenders
11 Dora the Explorer Dora is the main protagonist in the show "Dora the Explorer". Her main occupation is exploring with her monkey friend, Boots.

Dora errors:
1. Dora ventures outside without her family's permission.
2. Dora's family does not get crossed if she returns home from adventures. 3. Me: Dora the bridge is in front of you! Dora : Where? Me: In front! Your eyesight needs help?!
4. Dora screams loud.
45. Dora is a person who travels with a talking monkey and backpack
6. When the fox tries to grab her stuff Dora says " Stop it! "

Number 1! Please. She's so annoying! I liked her when I was a child because I liked when she asks again and says your'e right. Please please! Please! I'm not going to stop
D-dumb. Don't watch
O- obnoxious!
R- retarded!
A- annoying. Like, obnoxious!
Decoded your dora the obnoxious explorer who never actually explores,

I agree! I hate Dora ever since I was born. She is dumb and annoying and stupid. I hate everything about her. Her hair and her face there just dumb. This should be at the top because she is dumb.

That show is for babies you coward. I saw that on one episode that you were running away from that stupid bear. You should have been dead already you idiot! Anyone agree with me!

12 Stimpy- The Ren and Stimpy Show

Stimpy is better than Patrick Star and a classic example of stupidity. Because Ren and Stimpy is a cult classic than perverted SpongeBob. I hope the Ren and Stimpy revival comes this year (2021) along with Beavis and Butt-head, who are both characters with classic and hilarious "stupidity".

Stimpy... A total classic example of stupidity... I really miss him and Ren especially when Ren would try to kill him for his stupidity which always ruined Ren's plans

So dumb, pretty sure his dumbness and his big nose inspired all a generation of idiot cartoon characters... His brain pop up through his hear when he bends over...

Loved this show, Stimpy was, and I quote "Such a stupid idiot! "

13 Spongebob Squarepants SpongeBob SquarePants is a fictional character and the titular character and protagonist of the American animated television series of the same name.

SpongeBob is about as dumb as it gets. I'm so ashamed to have liked the show when I was young and foolish. His laugh is so incredibly annoying, and just... Ugh. Everyone in Bikini Bottom is stupid. And Bikini Bottom is such a terrible name.

One dumb person is funny.
Two? Not so much...
I don't like SpongeBob, and I must admit, after season 4, the Sponge and Starfish duo have grown moronic, obsolete, and quite unlikable. They grant torture to those who are so unfortunate as to meet them.

Yeah but SpongeBob is one of the most beloved cartoon characters ever! He is very nice happy funny and silly but he is pretty dumb. But he's also AWESOME!

He was in Seasons 6-9A but otherwise he has a HUGE advantage over Patrick when it comes to intelligence

14 Officer Barbrady - South Park Officer Barbrady is a recurring character in the animated adult television series South Park and is the town's main police officer, with a relatively poor vocabulary. He is extremely incompetent at his job, usually being incapable of solving the crimes he is legally obliged to investigate.

T IS FOR TURTLE. He is so dumb whenever he appears on a screen you are expecting for him to say or do something dumb that will make you laugh.

This list was tough but I had to vote he, sure patrick peter homer n d rest is stupid but hey dis guy so dumb he can't even read

Why is he barely in the show anymore, I want him back, I hate that red headed cop

Lmfao! A dumbass who can't spell is criticizing a character who can't read!

15 Beavis - Beavis and Butthead Beavis is a fictional character. He is one of the young teenaged protagonists on the MTV animated series Beavis and Butt-head.

Why is he on #17? He belongs to #2 behind Homer Simpson to me. I don't care about nor like nearly all of the characters. Beavis is funnier and I love his Cornholio personality. That show was a classic and is one of the best cartoons. I can't wait to see its revival on Comedy Central!

Rant: Beavis And Butt-Head What?! More Like Stupid And Crap-Head! Oh My God! This Show Sucks! Beavis And Butt-Head Don't Stop Laughing Like Idiots They Are So Annoying! I Want To Jump Into The T.V. Screen And Goes To Makes Him A Mega Blaster Falcon Punch In That Ugly Faces

This show is VERY fun to watch ad their stupidity makes it better!

Beavis should obviously be number 1 and butt head number 2.

16 Cheese - Foster's Home for Imaginary Friends

He is actually rude, he doesn't even say please.

I love him but he's ridiculously dumb

I like chocolate milk

Favorite show

17 Chris Griffin - Family Guy Christopher Cross "Chris" Griffin is a fictional character from the American animated television series Family Guy.

(Peter "wins" Trivial Pursuit)

Chris: My dad's smarting than your dad!

Meg: We have have the same dad, idiot!

Chris: Yeah, but mine's smarter!

Retarded fatty like his Dad!

18 Buhdeuce - Breadwinners Buhdeuce is one of the main characters in the Nickelodeon show "Breadwinners". He is usually around with his friend "SwaySway", and they are both ducks.

Yeah buhdeuce is dumb but not in a good or comedic way

In some episodes, he is smarter than Sway.

19 Sanjay - Sanjay and Craig Sanjay is one of the 2 main characters starring in the Nickelodoen show "Sanjay & Craig". Sanjay is an Indian boy who is usually around with Craig, a talking snake who is acquainted with Sanjay.

One example, he dance very stupid on the theme song when on the part Sanjay and Craig say "YO! WHAT'S UP! " Also Craig too.

Dresses up as a half naked fat guy imitates laughs eats floor gum and thinks an inflatable gorilla is heaven

He thinks that acting like a complete imbecile is cool.

Is he the human?

20 Derpy Hooves - My Little Pony: Friendship Is Magic Derpy Hooves is a female Pegasus from the 2010s kids show My Little Pony:Friendship is Magic. She is described as dumb and clumsy. Her occupation is a delivery mare.

Dumb but funny. Derpy wants muffins!

"I just don't know what went wrong! "

She's so adorable! #save derpy

It's in the name.

21 Uncle Grandpa - Uncle Grandpa Uncle "Larry" Grandpa is the main protagonist of the series Uncle Grandpa created by Peter Browngardt.

This shoul be number one, this person is just stupid, just looking at the show titles just makes him look more dumb and even the fact that he is the uncle And grandpa of every child in the world is so confusing.

This person is a FRAUD. Yup, that's right! How can you be someone's uncle and grandpa?! If I were president, I can immediately give him the death penalty. KISS HIS ASS GOODBYE!

Uncle Grandpa is the dumbest man in the world, his voice gives me a headache

Uncle grandpa is so stupid he sold his car for gas money

22 Gir - Invader Zim
