Episode Title:
The Exterminated Capital! The Twirly Hat Crew Arrive!.
Episode Description:
Master Cat Viper fights against Jack in his human form. Eventually the sun rises and the day shift takes over as Duke Dogstorm reappears to once again do battle with Jack. Wanda explains to Luffy and the others that the battle dragged on for five days, during which the two rulers repelled the enemy forces but were unable to bring down Jack. On the fifth day Jack out of anger unleashed a poison gas weapon on the whole city which quickly brought the Minks resistance to an end. Jack then proceeded to torture the two rulers and their subordinates to the point where he cut off Duke Dogstorm's leg and Master Cat Viper's arm. She then explains how Jack left the island after hearing Doflamingo's defeat to rescue him and was supposedly killed in the attempt. The very next day Sanji's group lands at Zou and stumbles upon the destroyed capital finding the wounded and injured citizens slowly dying from the poisonous gas.
