One Piece: 6 Characters Luffy Must Surpass In The Final Saga

Luffy, the protagonist of One Piece, is going strong on his quest to claim the One Piece, and he has already shaken the New World, especially in the Final Saga, starting from the events on Egghead Island. Luffy has recently become an Emperor of the sea, and that in itself means that he has grown tremendously in terms of strength over the years. Of course, while this has been a great step for Luffy, he's still quite young and has a lot of potential to fulfil.
