Hardy Jones and his gang begin to seize the Fish-Man Island. The villains intend to execute King Neptune and then unleash a bloody war against the entire human race. Consumed by hatred, they know neither mercy nor fear... However, on the same island, the Straw Hat crew arrives. Luffy and his comrades are not ready to turn a blind eye to what is happening – they are preparing to fight Hardy! The only problem is that this fish-man has an ace up his sleeve: special energy steroids that turn him into a true monster.
