Dim-witted, aloof, carefree, and childish, are some of the words that can be used to describe many iconic shonen protagonists that have risen to prominence over the years. This variant of the traditional hero, is generally referred to as the "dumb protagonist." Some of the most recognizable main characters from shonen manga and anime, such as Dragon Ball's Son Goku, Naruto's Naruto Uzumaki, and One Piece's Monkey D. Luffy, fall into this category.
