"Grand Battle" was, on PlayStation, the main line of fighting games starring One Piece's characters, and this WonderSwan entry brought that idea of one-on-one battles with Luffy, Zoro, Nami, and the rest of the crew to the handheld's screen, with the scale and animation adjustments that platform jump demanded. By that point, Eiichiro Oda's manga was already one of the biggest phenomena in Shonen Jump magazine.
It's one more piece of the massive backing Bandai gave WonderSwan with its own licenses, at a time when the handheld needed strong franchises to compete against Game Boy.
