One Piece: Pirate Warriors 4 is an upcoming Musuo game that puts players in the shoes of One Piece characters, as they wade through hordes of foes and take down massive boss monsters in battle.
The last One Piece: Pirate Warriors game was released in 2015, which means that the latest entry in the series is adding new characters that have been introduced to the story since then, as well as existing characters from the series that had their abilities fleshed out after the Dressrosa arc. This isn't a complete list, as more DLC characters will be revealed in the future, but these are the characters who will be available at launch.
