One Piece is a Japanese anime series based on the manga series written and illustrated by Eiichiro Oda. One Piece follows the adventures of Monkey D.

During Momocon 2013, the Toonami staff stated that they had re-acquired the rights to the series and that One Piece would return to the lineup, in April 2013.
The series returned to Toonami on May 18, 2013 with episode 207 of the “Long Ring Long Island” arc (or “Davy Back Fight” arc as it’s also known), due to the fact that a lot of the episodes preceding 207 were already shown on Toonami, and because every episode after 207 is in HD. The series is rated TV-14-DLV on Adult Swim.
The series begins with the execution of Gold D. Roger, a man known as the King of the Pirates. Just before his death, Roger announces that his treasure, the One Piece, will be up for the taking, causing the Great Pirate Era to begin. As a result, countless pirates set out to the Grand Line to look for the treasure. Twenty-two years have passed since Roger's execution, and Monkey D. Luffy, a young pirate inspired by his childhood idol and powerful pirate Red Haired Shanks, has since set off on a journey from the East Blue Ocean to succeed Roger and find the legendary treasure. In an attempt to organize his own crew, the Straw Hat Pirates, he befriends many different crew members, each with unique skills and abilities, that he meets on his journey to find The legendary treasure One Piece.

Luffy, a rubber-man and captain of the Straw Hat Pirates; Roronoa Zoro a swordsman and former bounty hunter; Nami, a navigator and a thief; Usopp, a sniper and a liar; Sanji, a womanizing chef; Tony Tony Chopper, an anthropomorphized reindeer and doctor; Nico Robin, an archaeologist and former member of the Baroque Works; Franky, a shipwright and self-made cyborg; and Brook, a living skeleton and musician.
