One Piece

The series begins with a boy named Monkey D. Luffy, inspired by his childhood hero, the pirate known as "Red-Haired" Shanks, going on a journey to find the One Piece. Along the way, he organizes and leads a crew named the Straw Hat Pirates. The crew consists of a swordsman and first mate named Roronoa Zoro; the navigator and thief Nami; the cowardly sharpshooterUsopp; the womanizing chef Sanji; the doctor Tony Tony Chopper, an anthropomorphized deer; the archaeologist Nico Robin, a former enemy of the crew; the cybernetic shipwright Franky; and a musician skeleton named Brook.

The crew faces diverse villains such as Baroque Works, Eneru, the Seven Warlords of the Sea,Blackbeard and the Marines. The marines are the subordinates of the World Government, who seek justice by ending the Golden Age of Pirates. Many background story elements involve the delicate balance of power between the World Government and the world's most powerful pirate crews, especially the Four Emperors, the four most powerful pirates in the world.

After the death of Luffy's adopted brother Portgas D. Ace and one of the Four Emperors named Whitebeard, the Straw Hat Crew undergoes rigorous training regimens. Two years later, the crew regroups at Sabaody Archipelago and set out on a journey to the New World.
