Episode 504

"To Fulfill the Promise - Separate Departures!" is the 504th episode of One Piece.

Summary
Ace starts to care for Luffy more as a brother after he was nearly mauled to death by a bear. Ace then sets off on his own seven years later, bidding the moutain bandits and Luffy farewell. Dogra comes by a few months later and shows Luffy a newspaper that talks about Ace and his new crew. Three years later, Luffy sets out from the Goa Kingdom. He then beats up the Lord of the Coast for eating Shank's arm and to show the results of his forest training.

Present time: Luffy proclaims that he is weak in front of Jinbe, implying that he can't be the Pirate King like he wanted, considering that he wasn't able to protect Ace or his friends.

Anime and Manga Differences

 * Luffy defeating the Lord of the Coast is properly shown for the first time in the anime version in this episode.
 * Sabo appears to encourage Luffy to aim the center of the rock after he failed the first time while he practices his Gomu Gomu no Pistol. In the manga, Luffy breaks the rock on his first try.

Trivia
