10) Natsu Natsu is not concerned about anything that doesn't have to do with fighting or his friends. All of his actions belong to either fighting or caring for his friends.
9) Asta Asta is another one of those shonen protagonists that don't have the brains for anything except fighting. He even pursues a nun, which is dumb even for dumb anime characters.
8) Luffy Luffy is called a blockhead or dumb even by his friends in the series. Whilst he has an amazing mind when it comes to strategizing, overall he is dumb.
7) Sawako Sawako is not dumb by any means. But she is very naive. She will believe anything other people say and she can't differentiate between good and bad people.
6) Hashibira Inosuke Inosuke is like a child. All anyone needs to do to get him to do something is challenging him into doing it.
5) Rak Wraithraiser Rak is the kind of fighter who relies only on instinct alone. When it comes to a logical decision, he panics and starts climbing walls.
4) Jessie And James It takes a different type of stupidity to lose to a child that cannot remember the names of Pokemon. But somehow Jessie and James have been managing for a long time.
3) Goku Goku is a peak example of someone who has nothing in their mind except fighting. He has no sense of self-preservation and his actions are sometimes downright dumb.
2) Isaac And Miria Even a blockhead will notice when he's not aging, but it took them both 70 years to realize that they are not aging.
1) Nendo Riki It takes someone very stupid who has no thoughts in his head to throw off Saiki Kusuo who can read minds. Even Saiki was shocked at Nendo's level of stupidity.
