One Piece follows the adventures of Monkey D. Luffy as he pursues his dream to find Gol D. Roger's treasure and become the Pirate King. After obtaining this title, Gol D. Roger willingly handed himself over to the Marines, and his execution went down in One Piece history as one of the most emblematic events of the series. In revealing the existence of a great treasure, he motivated an entire generation of pirates to pursue the freedom to follow their dreams, with his last words serving as a catalyst to the events taking place in the current narrative.
