Wishful thinking but either way I could see them doing what Naruto did and still continue the story in some way after he becomes pirate king or whatever they want to do at the end
If there is a spin off I think it would be a flashback to Rogers time as a pirate. It will continue to go on in some way either way. It makes too much money and there are so many characters you can get into
This isn't solely about finding the One Piece. The upcoming war between Marineford and the Revolutionary Army has been prominent enough that makes me think that'll be the spin off, but not enough that it'll be included in the original
Nearly every One Piece character is awesome haha, speaking of good characters ive started watching My Hero Academia. It will be the next
DBZ/One Piece, awesome powers and great cast of characters.
