The North Blue is an ocean in the One Piece World. North Blue, like its sister seas, comprises almost entirely of ocean, with a few scattered islands and a border with the Red Line. It is known to be the birthplace of the Straw Hat Pirates' Cook, Sanji, as well as that of his family; the legendary explorer Montblanc Noland and his descendants; the Bellamy Pirates and the origins of three members of the The Worst Generation: Trafalgar Law, Basil Hawkins, and X Drake. The Donquixote Pirates crew, led by Donquixote Doflamingo, was also started in this sea, where it achieved infamy.
