Episode 389

"Explosion! The Sunny's Super Secret Weapon: Gaon Cannon" is the 389th episode of the One Piece anime.

Short Summary
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 could get revenge on Sanji. He then uses steel nets to nearly drown Sanji, until Keimi saves him. Meanwhile, the Flying Fish Riders attempt to crush the Thousand Sunny, but with the newly installed Gaon Cannon, they were quickly defeated. Duval, in his anger, decides to run over Luffy with his bull, but to everyone's surprise Luffy easily stops the bull without even attacking it, by unknowingly using Haki. Sanji then comes on shore and deals the final barrage of kicks.
