In One Piece, Luffy's straw hat was given to him by Red-Haired Shanks, bound by a promise that they would only meet again when Luffy became a great pirate. Years later, that promise is still treasured by Luffy.
For Luffy, the straw hat is a constant reminder of what he must accomplish. That's why the yellow straw hat has always been associated with Luffy from then until now (hence his nickname Straw Hat).
Not only does he want to become the next Pirate King, but he also has an unknown dream that he wants to achieve after reaching the final island of Laugh Tale.
On Twitter/X, one fan revealed: “Not very useful information: Luffy always wears a straw hat when performing his duties as captain. The captain wears a straw hat!”
The straw hat was passed from Roger to Shanks, and Shanks passed it to Luffy. All three of them are incredible in their own way. While Roger went down in history as the first Pirate King, Shanks became a Yonko a few years ago. Now, Luffy and Shanks share the title of the Four Emperors, the emperors of the sea.
So we can understand that the straw hat here is the embodiment of human dreams, it is like an invisible thread of time that helps inherit the will of the characters.
Despite all that he has achieved, Luffy is still as foolish and carefree as he was in the beginning. However, there are times when he also has to make choices befitting a captain. This is when Luffy makes sure he is wearing the straw hat on his head.
“This is why our captain is the best! Now that you mention it, he's such a lovely captain! I like that about him!”one fan added.
“He is 'Straw Hat Luffy' of the Straw Hat crew, I am very touched by the way Luffy shows that whether intentionally or unintentionally.”another person expressed.
