Top 10 Dumbest Cartoon Characters

1. Patrick Star - Spongebob Squarepants

   

   Patrick Star is a fictional character in the American animated television series SpongeBob SquarePants. Created and designed by Stephen Hillenburg, the series' creator, Patrick first appeared in the pilot episode "Help Wanted" on May 1, 1999. He is voiced by Bill Fagerbakke.... 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.

   This is a character I know and recognize from childhood. There were some things I liked about Patrick and many I didn't like.

   Also, I hated that Patrick was having too much fun with SpongeBob's new net and wasn't listening to him in the Best Day Ever episode.

2. Peter Griffin - Family Guy

   

   Peter Griffin is the main protagonist and titular character of the American animated sitcom Family Guy. Peter is known for being foolish and doing random things for the sake of comedy. His wife, Lois Griffin, often nags him. He didn't pass the third grade, and his father is an Irish man.... read more

   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. Ed - Ed, Edd And Eddy

   

   Ed is one of the three main characters in the Canadian-American animated television series Ed, Edd n Eddy. He is the strongest and least intelligent member of the Eds. Ed is known for his simple-mindedness, immense strength, and love of comic books and monster movies.

   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!

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

4. Homer Simpson - The Simpsons

   

   Homer Jay Simpson is the main protagonist of the American animated television series The Simpsons, serving as the patriarch of the eponymous family. It is implied that he is not very intelligent, with a crayon stuck in his brain often cited as the reason. He works at the Springfield Nuclear Power Plant... read more

   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

5. Ralph Wiggum - The Simpsons

   

   Ralph Wiggum is a supporting character in the animated television series The Simpsons. He is the son of Chief Clancy Wiggum and is known for his nonsensical and often humorous remarks. Ralph is voiced by Nancy Cartwright and features prominently in several episodes, including I Love Lisa and This Little... read more

   You know you're stupid when you once had a trope for incredibly stupid characters named after you. TVTropes.com 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.

   Homer is only ranked higher because he's more popular. At least he can speak in complete sentences and say things that are usually related to the topic.

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 Turner's fairy godfather in the animated television show The Fairly OddParents. He's Wanda's husband and Poof's father. Cosmo is very immature and often acts foolishly, but he is also charming, loving, and devoted to his family.

   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. Officer Barbrady - South Park

   

   Officer Barbrady is a recurring character in the animated adult television series South Park. He serves as the town's main police officer and is known for his limited vocabulary and ineffectiveness. He often fails to solve the crimes he investigates, making him a source of comic relief.

   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!"

10. 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. He is a large pink rabbit known for his laziness and love of food. Despite his flaws, Richard is a loving father and husband.

    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.

The Newcomers
11. ?

    Gus Turner - Robotboy

    Not only is this boy extremely dumb, self-centered, unfunny, and a terrible friend to Tommy, but he also can't help putting his friends in danger.

12. ?

    Jack - The Nutshack

The Contenders

13. Leni Loud - The Loud House

    

    Leni Loud is a fictional character from The Loud House. She is the second oldest sibling in the Loud family and is known for being ditzy, forgetful, and absent-minded.

    Despite her flaws, Leni is kindhearted and always eager to help others. She is also a talented fashion designer who takes pride... 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.

    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.

14. Spongebob Squarepants

    

    SpongeBob SquarePants is a fictional character and the titular protagonist of the American animated television series of the same name. SpongeBob is known for his bright optimism and naive, childish tendencies. He often gets into trouble in Bikini Bottom.... read more

    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!

15. Cheese - Foster's Home for Imaginary Friends

    Cheese from Foster's Home for Imaginary Friends was really annoying in the episode "The Big Cheese." He doesn't know when to be quiet or take a hint. I find his lack of understanding disturbing.

    I love him, but he's ridiculously dumb.

16. Dora the Explorer

    

    Dora is the main protagonist in the animated television show "Dora the Explorer." Her primary role is to go on adventures and solve problems with her monkey friend, Boots. The show is designed to be educational, teaching children basic Spanish and problem-solving skills.

    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.

17. Beavis - Beavis and Butthead

    

    Beavis is a fictional character. He is one of the teenage protagonists on the MTV animated series Beavis and Butt-Head. Created by Mike Judge, the character is known for his crude humor, distinctive laugh, and commentary on music videos.

    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.

18. 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.

19. 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.

20. Uncle Grandpa - Uncle Grandpa

    

    Uncle "Larry" Grandpa is the main character of the animated series Uncle Grandpa, which was created by Peter Browngardt. In the show, Uncle Grandpa is portrayed as the magical and eccentric uncle and grandfather to everyone in the world. He travels around in his RV helping children with their problems... read more

    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.

21. Johnny Bravo

    

22. Chris Griffin - Family Guy

    

    Christopher Cross "Chris" Griffin is a fictional character from the American animated television series Family Guy. He is the teenage son of Peter and Lois Griffin and the older brother of Stewie Griffin. The character is voiced by actor Seth Green.

    (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!

23. Derpy Hooves - My Little Pony: Friendship Is Magic

    

    Derpy Hooves is a female Pegasus character from the 2010s animated television show My Little Pony: Friendship is Magic. She is characterized by her crossed eyes and clumsy behavior, which has made her a fan favorite. Her role within the show includes working as a mail delivery mare in Ponyville.

    Dumb but funny. Derpy wants muffins!

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

24. Butt-Head - Beavis and Butt-Head

    

    Smarter than Beavis, but that's a very low bar.

25. Bolbi - Jimmy Neutron

26. Sanjay - Sanjay and Craig

    

    Sanjay is one of the two main characters in the Nickelodeon animated series "Sanjay and Craig." Sanjay is an Indian-American boy who goes on wild adventures with his best friend Craig, a talking snake. The show premiered in 2013 and ran for three seasons.

    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.

27. Fred Fredburger - The Grim Adventures of Billy and Mandy

    

    He uses the judge's mallet to try to make a chair by smashing it in the courtroom wall. Complete, hilarious stupidity!
