One Piece is currently in the Elbaf Arc, meaning the story has progressed deep into the Final Saga, where Luffy and the Straw Hats are giving their all to claim the One Piece treasure. This is also the moment when Oda will finally reveal the most important characters to fans.
Naturally, Luffy tops the list of key characters as the protagonist and the story’s driving force. Alongside him, the Straw Hats play an extremely important role, though some members like Zoro and Sanji often get more attention than others such as Usopp.
However, in the Final Saga, there is one character who will undoubtedly be more important than most of the Straw Hats, and that is one of the Four Emperors.
Shanks is as important as Luffy in the Final Saga

When it comes to the most important character throughout the Final Saga, it’s obviously Luffy. But right after him is Shanks. Oda clearly has big plans for Shanks in the final story, which is evident since the author has kept Shanks in reserve until now. Oda himself has said that a clear sign One Piece has entered its final saga is the frequent appearances of Shanks.
“When Shanks appears often in the manga, you can tell One Piece has entered its final saga.”, Eiichiro Oda.
Moreover, those who know the ending of One Piece and have heard Oda’s detailed story outline, like director Goro Taniguchi (who directed One Piece Film: Red), have previously made a striking statement: “Shanks is as important to One Piece as Luffy.”

Shanks’ role as the “child of destiny”
The truth is, Oda himself sees Shanks as a very special character with a huge role in the Final Saga. Oda even feels a connection to Shanks, considering him someone he aspires to be like because of his exceptional qualities.
This strongly suggests that after Luffy, Shanks is the most important character, playing a pivotal role in shaping One Piece’s conclusion. Shanks’ role in the Final Saga will be extremely significant, and it’s only a matter of time before this Emperor takes a more direct part in the final battle for the treasure.
