There once was a pirate known as the Great Gold Pirate Woonan, who obtained almost one-third 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 Tobio, 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 first One Piece film, even done before Sanji was in the franchise so super early. It was fun like a lot of early One Piece is fun, not too much action, just sorta goofy characters being goofy. Usopp shines the most in this.
A movie about finding a Macguffin treasure. Very fitting for One Piece's first movie. The symbolic plot serves as a great introduction to the main point of the series - the journey is better than the destination.
One for the nostalgia. A simple movie with a little aesop and plenty of funny faces.
