Episode 511

"An Unexpected Return! Luffy, to Marineford!" is the 511th episode of the One Piece anime.

Long Summary
The episode starts with a view of Marineford being rebuilt. It shows a room full of vice-admirals as Lieutenant Commander Brandnew talks about how Luffy survived the war and caused trouble again. A flashback follows, showing what happened two days ago. Two reporters are seen talking about how the Marines will go after the pirates involved in the war. Suddenly, some Marines see the warship which Luffy, Jinbe and Rayleigh are on. They make a full circle around Marineford before entering the bay (which is done in a funeral). After that, all three of them get to the plaza. Luffy then runs toward the Ox Bell and rings it sixteen times, after that he goes to a huge crack in the ground and drops a bouqet of flower in it and held his hat to his chest in a manner of paying respect. Soon enough a huge whale-shark appears in the bay as Luffy, Jinbe and Rayleigh run away. After that, the newspapers print the story and deliver it to Sabaody Archipelago, Alabasta, Water 7, and Foosha village. The flashback ends as Brandnew states that it is humiliating for them to have let Luffy go.

After that there is a scene showing the Gorosei discussing who should fill the vacancies in the Shichibukai positions and that Blackbeard is turning out to be a lot of trouble. They also commented on how those with the "D" are beginning to stir up trouble at the same time.

The next scene shows World Government Commander-in-Chief Kong and former Fleet Admiral Sengoku discussing Sengoku's retirement. Sengoku also recommends Admiral Aokiji to be the next Fleet Admiral.

The scene changes to Coby, Helmeppo, and a doctor in the hospital, discussing how Coby has obtained Kenbunshoku Haki. Coby, talking within himself states that he feels different with this new power and he has to train more to become stronger; as strong as "him" ("him" refering to Luffy).

After that, Admiral Aokiji and Smoker talk about what Luffy did at Marineford and about Smoker's transfer to the Marine base G-5.

In the New World, Eustass Kid and his crew are talking about Luffy's actions. Kid asks what the Ox Bell is. Killer explains what it is and why Luffy rang it sixteen times.

The scene changes to Capone Bege's ship, which is being pulled up to a huge black ball in the sky, and Urouge's ship, which is approaching an island that is constantly being hit by lightning. An old woman offers to sell the crew some umbrellas. It then goes back to Kid as he declares that he will defeat Luffy in the New World.

Anime and Manga Differences

 * In the anime, after Coby learns that he has Haki, he thinks to himself that now he is like a different person, and maybe, if he works hard, he will be able to get as stong as "him".
 * In the anime, Luffy's actions in Marineford are seen, though in the manga they were only explained later.
 * Bege and Hawkins read about Luffy's actions in the anime.
 * In the manga, the pirates Kid crucifies are impaled with multiple swords and screws is in each of their chests, while in the anime only the screws are shown.
