Rubber-bodied rookie Monkey D. Luffy drifts out of Foosha Village in a barrel, clobbers iron-mace Alvida, liberates timid deckhand Koby, and vows to claim the legendary One Piece and crown himself Pirate King.
In Shells Town, Luffy frees feared bounty hunter Roronoa Zoro from corrupt Marine Captain Morgan's clutches, gaining a swordsman crewmate and drawing Navy fire.
Luffy and Zoro battle axe-armed Captain Morgan and cowardly son Helmeppo to save Coby and a captive girl, toppling the tyrant and earning a Marine bounty on Luffy's head.
On their first voyage together, Luffy recalls how red-haired pirate Shanks inspired his dream--and sacrificed an arm to save him--while Coby stays behind to join the Marines.
Luffy and Zoro arrive in Orange Town, reluctantly ally with thief Nami, and clash with body-splitting clown captain Buggy, whose devastating Buggy Balls threaten to level the city along with their Grand Line dreams.
To save Orange Town, Luffy faces beast-tamer Mohji and his giant lion Richie, while Nami slips off with Buggy's loot and an injured Zoro shields the townsfolk.
Buggy reunites his body, fires a colossal Buggy Ball, but Luffy ricochets it back, wrecking the pirate's ship; Nami steals the Grand Line map and joins the voyage.
