One Piece: The Straw Hat Grand Fleet Might Play a Bigger Role Than Fans Expect

The pirate world of One Piece is ruled by the likes of the Yonko, also known as the Emperors of the Sea, who dominate the second half of the Grand Line, called the New World. Being Emperors, it's been established that their authority over numerous territories is absolute. As such, the Yonko of the Sea have several allies which further add to their already monstrous pirate crew.
