One Piece Episode 666 English Subbed Episode Title:The End of the Match?! A Surprising Result of Block D!.Episode Description:As the dust clears, the last fighter standing turns out to be Rebecca making her the winner much to the dissatisfaction of the announcer and the crowd. Speculations of Rebecca cheating were thrown throughout the crowd but Rebecca was the only one who saw what really happened. During the fight, Rebecca saw Cavendish fall asleep in the middle of the battle. Before the other fighters would capitalize on their sleeping target, Cavendish promptly woke up with a sinister face that promised torment for his enemies. In that instant, Cavendish moved like the wind, cutting down every fighter in his way. Rebecca however saw this and barely manages to avoid a fatal strike from Cavendish, who then fell asleep again. Outside, Vice Admiral Bastille finished explaining to an officer about what happened in the colosseum as this was the work of not Cavendish, but his alter ego Hakuba, a dangerous man who eluded the marines years ago for his dangerous technique. At the Palace, Doflamingo is standing before King Riku who is chained up. Doflamingo gloated that Viola's hope of the Straw Hats defeating him and freeing Law is worthless, as he had full confidence that his men will prevent them from breaching his operations and believes that Luffy is still trapped in the colosseum. At that moment, Robin and Usopp have successfully infiltrated the basement harbor, and Luffy's group ran into Viola who wants to help them in entering the palace.
