However, against all odds, the series' Egghead Island Arc is somehow poised to spawn an even bigger conflict, due in large part to the major role that the World Government and their constituents play in the process. Their arrival at Egghead Island raises the stakes higher than ever before, but it also serves as an unexpected reminder of a previous One Piece arc.
