The East Blue is an ocean in the One Piece World and was the setting of the first six arcs of the manga and anime and the anime only Warship Island arc. East Blue, like its sister seas, comprises almost entirely of ocean, with a few scattered islands and a border called the Red Line.
In the Grand Line, pirates who are considered great and threatening in the East Blue are regarded as low rate compared to pirates in the Grand Line, such as Dracule Mihawk. The sea's weak status was demonstrated by Mihawk when he singlehandedly took out every ship in Don Krieg's fleet (except Krieg's flag ship, which he later hunted down) when they tried to enter the Grand Line. However, the East Blue is also the birthplace of many powerful characters (which is ironic, since it's the weakest of all seas), such as Monkey D. Luffy, Roronoa Zoro, Monkey D. Dragon and the late Pirate King, Gol D. Roger.
