Explosion! The Sunny's Super Secret Weapon: Gaon Cannon

Duval reveals that he was once a small-time bandit until Sanji's wanted poster came to light. Since then, he hid his face with the iron mask until he would get revenge on Sanji. He then uses steel nets to nearly drown Sanji, until Camie saves him. And with that, Sanji deals a fatal kick combo at Duval's face. Meanwhile, the Flying Fish Riders attempt to crush the Thousand Sunny, but with the newly installed Gaon Cannon, they are quickly defeated.
