Monkey D. Luffy

Monkey D. Luffy is the main protagonist of the series One Piece.

At first glance, Luffy does not appear to be very intelligent; his apparent lack of intelligence is the source of his brave attitude towards life.Luffy can easily be amazed by the simplest things, such as hermit crabs, and can be confused by concepts such as that by digging a hole right next to another he may be unintentionally filling the other hole. He also has no knowledge of medicine, when Nami had a high fever he told her to eat cold food and later tried to make Zoro better (after battling Kuma) by pouring Sake onto him because Zoro likes sake. When attempting to think up a plan to get off of Amazon Lily, while he managed to make some logical sense of where to look, he is seen to strain himself and notes that he is going to feel sick from too much thinking
