One Piece: Stampede

Said to be comparable to the Ancient Weapons of old, the Marines’ trump card, the “Dyna Stones,” have suddenly been stolen by a group of renegade vigilantes. The terrifyingly powerful man responsible, former Marine Admiral “Z”, now stands in the path of Luffy and his Straw Hat Pirates. Can the Straw Hats defeat “Z” and his crew, or will the New World meet its end at the hands of this mad man?

There once was a pirate known as the Great Gold Pirate Woonan, who obtained almost 1/3 of the world's gold. Over the course of a few years, the pirate's existence faded, and a legend grew that he disappeared with his gold to a remote island, an island pirates continue to search for. Aboard the Going Merry, Luffy and his crew, starved and reckless, are robbed of their treasure. In an attempt to get it back, they wreck the getaway ship, guided by a young boy named Tabio, who's a captured part of El Drago's pirate crew. El Drago's love for gold has driven him to look for Woonan's island, and thanks to Woonan's treasure map, he finds it. During this time, Luffy's crew have been split up, and despite their own circumstances, they must find a way to stop El Drago from obtaining Woonan's gold.

The special will be a completely new work, featuring reanimated scenes from the beginning of the series through when the crew enters the Grand Line. The special is commemorating the manga's 20th anniversary, and will also feature anime versions of the original manga's chapter cover stories as part of the special's ending credits. The staff haven't yet clarified which cover story or stories will be animated. Additionally, the anime will feature a special 20th anniversary commemoration version of the original opening theme song "We Are!".

To commemorate the ONE PIECE anime's 25th anniversary: THE ONE PIECE anime by WIT Studio will recreate the story of the original ONE PIECE manga, starting from the East Blue arc.
