Typical of a shounen protagonist, Asta is loud and brash with few brain cells in his head. He is also quite clueless, not having a crush on him. But unlike many characters on the list, Asta is not an idiot and can use his brains when needed.

Yui Hirasawa

Japanese name Hirasawa Hirasawa Yui
Anime K-On!
Birthday November 27
Height 156cm
Hair color Brown

Next is the adorable Yui Hirasawa, the protagonist and one of the main characters of K-On! . Yui creates a high school group called After-School Tea Time with her friends, Mio, Ritsu and Tsumugi. She performs as the lead guitarist and lead vocalist of the band.

Yui is a light-headed person with a cheerful personality. On top of that, she is particularly lazy. Yui's grades at school are horrible in every subject except fine arts, and she is the only one in her class who usually has to retake exams.


13) Usagi Tsukino

Usagi Tsukino

Japanese name Usagi Tsukino
Anime Sailor Moon
Birthday June 30th
Height THAT
Hair color Blond
Eye colour Blue
Zodiac Cancer

No magical girl anime will ever be as iconic as Sailor Moon. Our heroine is none other than Usagi Tsukino, a teenager who discovers her power as Guardian of love and justice, becoming her alter ego, Sailor Moon.

Usagi is rather stupid and sometimes very whiny. She regularly gets low grades in school and is bad at anything tricky. Usagi can also be rather airy and clueless. But behind it all, she is a kind person and a wonderful fighter.

Tobio Kageyama

Anime Haikyuu!!
Birthday December 22
Height 72"
Hair color Black
Eye colour Dark blue
Zodiac Capricorn

is the deuteragonist and one of the main characters of the popular sports anime. He is a player and setter on the Karasuno High School volleyball team. Along with his teammate, Kageyama constitutes the team's "monster duo".

Unlike many characters on this list, Kageyama is a genius. Her volleyball talent and natural instinct for the sport are far superior to most. But he's actually a really stupid guy at everything other than volleyball, whether it's academics or social skills.


11) Naruto Uzumaki

requires little introduction. He is the protagonist and eponymous character of the iconic Shounen series.

Ninja of Konoha, Naruto lived a horrible childhood with a beast sealed inside him but he overcame his trauma to become the strongest ninja in the world and the Hokage of his village.

Like some of the other characters on the list of dumbest anime characters of all time, Naruto is talented in his skills, but his general intelligence cannot be counted out.

He is rather slow at most things and particularly clueless. But truth be told, much of his ignorance comes from the lack of attention he received as a child.


10) Gon Freecs

Hair color Black with green edges

Next up is Gon Freecss from . He is the protagonist of the series and one of the main characters in most arcs. Gon is a hunter who searches for his father with his best friend, .

While he's not a complete idiot, Gon is certainly not the brightest bulb in a room. He was found to be poor at mathematics and had difficulty understanding complicated plans. This is an ongoing gag in the series as his friends, particularly Killua, become exasperated by his friend's muteness.


9) Taiju Oki

Taiju Oki

Japanese name Big tree, big tree
Anime Dr. Stone
Birthday April 2
Height 189cm

Zodiac Ram

Taiju Oki is another good guy who is also one of the stupidest anime characters of all time. He has been her best friend since childhood. Along with the rest of the world, Taiju was petrified and was later petrified by Senku, waking up in a world of stones.

Taiju is a classic idiot. He is big and strong but when it comes to intelligence, he is the exact opposite of Senku. He is also very simple-minded and trusting, but can be trusted to keep a secret and follow a plan.


8) Natsu Dragneel

Natsu Dragneel

Japanese name Natsu Dragneel
Anime Fairy tale
Birthday THAT
Height THAT
Hair color Pink
Eye colour Black
Zodiac THAT

As we've seen so far in this list, shounen protagonists don't tend to be very intelligent. This is also true for. A mage from the famous guild, Natsu is looking for his adoptive father accompanied by his faithful cat companion, Happy.

Natsu is that character who is willing to put anything in his mouth, be it food or fire. He is also impetuous and short-sighted, preferring to act before thinking. The guy is also incredibly slow but he's much better than the rest of the characters on this list.


7) Yui Komori

Yui Komori

Japanese name Yui Komori
Anime evil lovers
Birthday THAT
Height 158cm
Hair color Platinum blonde
Eye colour Pink sorbet
Zodiac THAT

Protagonist of the Diabolic Lovers series, Yui Komori is undoubtedly one of the stupidest anime characters of all time. She comes to live with six brothers after her father leaves the country. Later, to her horror, she discovers that they are vampires.

Not only is Yui incredibly stupid, but she also has no personality at all. Even after learning their true nature as a vampire, she does not do the right thing and leaves, instead staying with them and is humiliated and abused daily. On top of that, she claims to love one of her attackers, Ayato. If that's not stupidity, what is?


6) Aqua

Aqua

Japanese name aqua
Anime KonoSuba: God's blessing on this wonderful world!
Birthday THAT
Height THAT
Hair color Blue
Eye colour Blue
Zodiac THAT

For our next entry of the stupidest anime characters, we have Aqua, one of the main characters of . She is the goddess responsible for Kazuma's reincarnation in a new magical world. After making fun of him for his hilarious and shameful disappearance, Kazuma chooses her to be his companion in the fantasy world.

Before choosing a goddess, Kazuma didn't know that Aqua would prove absolutely useless for anything except party tricks. She cries and contributes nothing. On top of her horrible personality, she's stupid as a rock. But no matter what you say about Aqua, she's comedic gold for the series.


5) Inosuke Hashibira

Inosuke Hashibira

Japanese name Inosuke Sakuhira
Anime Demon Slayer
Birthday April 22
Height 164cm
Hair color Black with blue tips
Eye colour Green
Zodiac Bull

We are now in the top five of this list and all of them are undoubtedly very stupid. At number 5, we have . Inosuke can be described as the pretty boy with the boar head and explosive personality. He is one of our main heroes and also one of the stupidest anime characters of all time.

Aside from being a totally simple and clueless guy, one of Inosuke's hilarious traits is his inability to remember names. Not only that, unlike any sane character, he is not one to plan, rather he prefers to run with his guns, swords in this case, running.


4) The Fusée team

Team Rocket

Japanese name Rocket Team
Anime Pokémon franchise
Birthday THAT
Height THAT
Hair color THAT
Eye colour THAT
Zodiac THAT

Ah, here we have the classic and one of the most iconic villains in anime. Team Rocket has played antagonists and their group since the beginning of the story. They are consistent in their pursuit of Ash's Pikachu or other rare Pokémon with many bizarre plans.

But in reality, the number of times they have succeeded in realizing their projects over the years can be counted on one hand. They're always tricked or just electrocuted and thrown into the sky way too many times to not count them among the top three stupidest anime characters.


3) Yoshiko Hanabatake

Yoshiko Hanabatake

Japanese name Yoshiko Hanabatake
Anime Aho girl
Birthday January 1st
Height 160cm
Hair color Light brown
Eye colour Reddish brown
Zodiac Capricorn

There's no need to repeat too much about how stupid Yoshiko Hanabatake is since she's the eponymous Aho Girl, which literally translates to "silly girl." She is a high school student who likes her neighbor and childhood friend, Akuru, even if he is constantly annoyed by her.

Yoshiko is the ultimate model. She is horrible at school, getting zeros even on multiple choice questions. On top of this, she is terribly clueless in social situations, not understanding when someone doesn't like her. Although his stupidest trait has to be his obsession with bananas.


2) Monkey D. Luffy

Monkey D. Luffy

Japanese name Monkey D. Luffy
Anime One piece
Birthday May 5
Height 174cm
Hair color Black
Eye colour Black
Zodiac Bull

The problem is that he is not only one of the most lovable characters, but also one of the stupidest characters ever. Protagonist of the ultra-popular series, Luffy embarks on an adventurous journey with his trusted but wacky crew to become the Pirate King.

If one were to write down all the examples of Luffy's stupidity, the pages would never end. He is a nervous being whose every thought stops at the mention of food. The guy doesn't want to be a hero because he thinks heroes share their meat and he doesn't want to do that! Enough said.


1) Son Goku

Son Goku

Japanese name Sonson Goku Kuu
Anime Dragon Ball series
Birthday THAT
Height 175cm
Hair color Black
Eye colour Black
Zodiac THAT

The only reason Luffy became the stupidest character ever is because not only is he totally stupid, but he may be the only one who thinks marriage is a type of food. He's a carefree guy who only wants to fight and become strong, and has no social skills.

Being the iconic character that he is, Goku is one of the original inspirations for the trope of stupid Shounen protagonists with endless stomachs. This makes him the true number one of all stupid anime characters.

This is where we end our ranking of the 15 stupidest anime characters of all time. These characters may be cool and have a lot of potential, but their idiocy would drive even the calmest person crazy. But unlike them, we will do the smart thing and bring you more exciting contents like this, so stay tuned with us.
