Sanji 👨🍳
Let's look at Sanji, the third person to join the Strawhats. And there is something that I find very enlightening about Sanji. As a character, he is representing a very deep scientific truth that scientist did not discover until quite recently. And I really can't tell how deliberate this was. In other words: I don't know if Oda knew about these discoveries when he created Sanji, or wether it was his intuition who created such an impressive representation.
