When he was captured and about to be executed, he revealed that his treasure called One Piece was hidden somewhere at the Grand Line. This made all people set out to search and uncover the One Piece treasure, but no one ever found the location of Gol D. Roger's treasure, and the Grand Line was too dangerous a place to overcome. Twenty-two years after Gol D. Roger's death, a boy named Monkey D. Luffy decided to become a pirate and search for Gol D. Roger's treasure to become the next Pirate King.
