Destroy All Pirates! The Straw Hats face their toughest opponent ever in the latest theatrical adventure from one of the world's most beloved franchises! When Luffy and his crew rescue a drowning man they have no idea what manner of evil they just welcomed aboard! The mysterious stranger turns out to be the former marine, Admiral Zephyr: a rampaging madman with a devastatingly deadly right arm called Battle Smasher. Better known as Z, this grief-crazed harbinger of doom is hell - bent on using the destructive power of the Dyna Stones to destroy the New World - and all pirates in it! Luffy is ready for a good rumble, but even the rubber is no match for the Sea Stone punching power of the Battle Smasher. With his crew in shambles and Thousand Sunny badly battered, Luffy must accept the aid of an unlikely ally if he hopes to save the world and continue his quest to become king of the pirates!
