As previously reported, the upcoming season will at the very least, cover the manga's Loguetown Arc to Drum Island Arc due to the season also introducing Tony Tony Chopper, the Straw Hat Pirates' doctor. There is still a high possibility the season will cover the Alabasta Arc. One Piece Season 2 is coming soon on Netflix.
