There were some differences between One Piece novels and comics. 1. Plot: The plot of One Piece's novel and manga is different. In the manga, the story revolved around Luffy and his pirate crew, but in the novel, it was more complicated and involved more political, historical, philosophical and other elements. 2. Character image: The character image in One Piece's novel and manga is also different. In the manga, Luffy was a very talented pirate captain. His image was very prominent, full of charm and dominance. In the novel, Luffy's image was more complete. He had more personality characteristics and character settings, which were more representative and deep. Chapter structure: The chapter structure of One Piece's novel and manga is also different. In comics, the structure of the chapters was relatively fixed, usually arranged according to the development of the plot. Each chapter contained some key plot twists and climaxes. In novels, the structure of the chapters was more flexible. The theme and content of each chapter were different. Sometimes, some memories or background stories would be inserted to enrich the plot. Although One Piece's novel and manga were slightly different, they were both excellent works of art. Both manga and novel were deeply loved by readers.
