Shanks is one of the most mysterious characters in One Piece, and also one of the most beloved ones. Having been introduced at the very beginning of the series, fans knew that Shanks had a major role to play, especially because he set Luffy out on his path to becoming the Pirate King. Ever since then, fans have been waiting to see more of Shanks, but Oda certainly kept him for something bigger much later in the story. In fact, Oda Once stated himself that Shanks will only start appearing more frequently in the story when One Piece enters its final phase.
