The Dressrosa Saga, also known as the Pirate Alliance Saga, is the name for the second saga for the second half of the manga and anime series, One Piece and is the eighth saga overall. The Straw Hat Pirates finally enter the New World, but soon receive a distress call from Punk Hazard island, home to a former laboratory of Dr. Vegapunk. They become entangled in the illegal experiments of Caesar Clown, and form an alliance with Trafalgar Law in preparation for dethroning Kaido of the Yonko. They challenge Donquixote Doflamingo and uncover a decade-long conspiracy on Dressrosa island. Their resulting actions against the Shichibukai send a massive shockwave throughout the world and result in the birth of the Straw Hat Grand Fleet.
