The One Piece world has seen the emergence of some incredibly powerful organizations over the years. The Marines, who are the military face of the World Government are quite possibly the strongest organization in the series at the moment. The likes of the Shichibukai roamed the seas with great freedom prior to their dissolution, while the Yonko rule the New World like Kings and hold tremendous power. At the same time, the likes of the Revolutionary Army exist to take power from the Celestial Dragons and liberate those who are oppressed.
