DID YOU KNOW?
The One Piece manga came out back in 1997? In fact, Eiichiro Oda, its creator, was only working as an assistant at Weekly Shonen Jump. One Piece started out as one-shots before it became an actual series. During the process of making the manga, he drew inspiration from various sources. Dragon Ball was an obvious one but he also drew from classic literary works. One of them, being Dante's Divine Comedy. Being a story about pirates, of course, he drew from the exploits of real Pirate figures as well.
As is the case with popular manga series, an anime adaptation was inevitable. With so many top One Piece arcs already under its belt, it was an opportune time to do so. The anime show is currently in its 20th season with an episode count of 891. The best One Piece episodes have been action-filled tearjerkers. The thing with adaptations is that they don't always stay faithful to the source material. Details get blurred during the transition from one form of media to another. The case is no different from One Piece, which is unfortunate. The manga version is still the ideal way to experience it and there is plenty of websites to help you out with this.
