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... read more

There's a fine line between likable dumb and atrociously dumb, and Patrick is nowhere near likable since he said, and I quote, "You can't expect my normal brand of stupidity. I like to mix it up to keep you on your toes." So, he's aware that 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. Enter's top 11 Patrick's a prick episodes and see why Patrick deserves the 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 downhill. 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.

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

Over time, he's gotten annoyingly and unlikably stupid, such as not listening to Brian when he warned him about consuming kerosene (resulting in him 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 remember in one episode Peter was on a plane. He got up, went to an emergency door that said "Do Not Open," and he opened it, and everyone flew out.

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 the characters on 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 or killed. Simpson is a great hero no matter how his intelligence is assessed. 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 adding "you're making a scene." -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 level of idiocy. Nowadays, Patrick is so dumb that it's not funny anymore, but rather more frustrating and annoying. Meanwhile, 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!

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 once 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 to sink below the average level of stupid, and only the dumbest of the dumb were put on this page (e.g., 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.

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 could snort the whole world up his nose!

Billy is the stupidest, dumbest, and most idiotic character on the face of the earth. He uses the Grim Reaper's 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 created... But that's what makes him funny.

I'm even watching The Fairly Odd Parents right now! Cosmo is dumb. He's funny.

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've ever heard.

Lindsay is a dumb character, but 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."

- Lindsay

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 the 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 sort of like a magic card where you dial the magic numbers for money to come out. He's no better than Homer.

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... read more

She fails her driving test a million times because she thought Lincoln's video game was realistic, and she drove on the wrong side of the road. She needed help building a puzzle that's for toddlers. She doesn't know how to turn on a lawnmower.

She couldn't get out of a crib and she called it jail. She can't speak English correctly. She didn't know she was in daycare. She bumps into walls all the time.

She forgets like everything. And in one episode, when Lynn was dressed the same as her, Leni thought Lynn was a clone of her.

The Contenders
11 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, not a 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 a generation of idiot cartoon characters. His brain pops up through his ear when he bends over.

12 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!

13 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 screen, you are expecting him to say or do something dumb that will make you laugh.

This list was tough, but I had to vote here. Sure, Patrick, Peter, Homer, and the rest are stupid, but hey, this guy is so dumb he can't even read.

(sees Cartman tied to a cross) "T is for Turtle!"

14 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!

This show is very fun to watch, and their stupidity makes it better!

Beavis should obviously be number 1 and Butt-Head number 2.

15 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 loudly.
5. 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!"

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

16 Cheese - Foster's Home for Imaginary Friends

I love him, but he's ridiculously dumb.

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 smarter than your dad!

Meg: We have the same dad, idiot!

Chris: Yeah, but mine's smarter!

18 Butt-head - Beavis & Butt-head

Should be higher

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 dances very stupidly in the theme song when 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.

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!"

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

This should be number one. This person is just stupid. Just looking at the show titles 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.

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

He's so damn dumb, it's funny and adorable.

That's what makes little Gir funny!

He's dumb. That's why he is amazing.

23 Wheat Bird - Angry Birds Show
24 Philip J. Fry - Futurama Philip J. Fry, or more commonly called Fry, is the main protagonist of Futurama. He is voiced by Billy West.

He doesn't know how to use a megaphone.

25 Goku Son Goku (Kakarrot) is the main protagonist in Dragon Ball franchise created by Akira Toriyama in 1984. He has many abilities like, super strength, utilization of ki, flight, teleportation, super speed, enhanced reflexes, and Super Saiyan transformation that increase strength, speed, and durability. His real name was suppose to be Kakarrot because that's his Saiyan name, and he is the son of Badrock, and Gina. His brother was Raditz. When they sent Goku (Kakarrot) to Earth his grandfather Gohan took care of him. Later on Goku didn't realize it when he was a kid, but he killed his grandfather Gohan because it was a full moon, and Goku looked at it, so he turned into a giant ape.

Goku: You can tell someone's gender just by looking? WOW!
