10) Monkey D. Luffy

Despite being the captain, Monkey D. Luffy is the least intelligent of the Straw Hat pirates in One Piece.Throughout the series, there are dozens of cases that demonstrate this, but a handful stand out in particular.One of the highlights of his story is when he eats a toxic fish and then tries to eat it again after being detoxed. Another is his unwillingness to obey orders during the Onigashima raid’s early stages. He is without a doubt the least intelligent of the Straw Hat pirates.
9) Roronoa Zoro

Straw Hat swordsman Roronoa Zoro is somewhat ahead of him due to his superior common sense. He can at least guide himself through daily life without difficulty, even if leading oneself in the right path is a problem.Aside from that, he shares Luffy’s short-sightedness when it comes to making plans and obeying commands.He isn’t the smartest member of the group, but he isn’t the dumbest either.
8) Brook

7) Jinbe

6) Vinsmoke Sanji

5) Nami

Nami is a talented ship’s navigator who employs connective thinking in her work. Her abilities as a cartographer highlight her intelligence even more, especially given her exceptional talent in a difficult subject. Her years of thieving and deception have also aided her intelligence by providing her with real-world experiences to draw on. This all adds up to her being in the top five of the Straw Hats in terms of IQ.
4) Usopp

3) Franky

2) Tony-Tony Chopper

1) Nico Robin

Nico Robin, on the other hand, is without a doubt the wisest of the Straw Hat pirates. She’s the last survivor of the Ohara people, who are known for their general brilliance and scholastic prowess. She’s also one of, if not the only, living One Piece characters who can decipher the Poneglyphs. Her brilliance presents itself in a variety of ways that cannot be questioned or contested. Nico Robin is without a doubt the Straw Hat crew’s sharpest pirate.
