The world of One Piece seems to always be expanding, and as Monkey D. Luffy and the Straw Hat Pirates embark on new adventures, they're often meeting new characters on their journey to find the legendary One Piece treasure. While there may be over 1,000 episodes of One Piece to binge-watch, not all of them are full of lighthearted adventure among Luffy and his friends. The series isn't afraid to go dark, exploring more evil characters and their motives, especially in a way that highlights how different they are from the show's protagonists.
