The Fishman Island Arc

The Fishman Island Arc is the twenty-fifth story arc. It is the second and last arc in the Fishman Island Saga of the One Piece series, continuing on from the Return to Sabaody Arc. The Straw Hat Pirates finally head for Fishman Island after their two year hiatus. But many surprises await them as they head for their undersea destination and even more so once they reach it. Fishman Island is the eleventh island that the Straw Hats encounter on the Grand Line.

After the Straw Hats escape, the scene changes to a section in Sabaody known as "No Man's Land". Coribou and Caribou along with their crew have captured the remaining Impostor Straw Hat Pirates and are digging their graves. The fakes beg the brothers to let them go but they refuse, revealing that they had planned to kill the real Straw Hats from the inside after joining them and were not amused when they found out they were lied to. When Fake Sanji continues to beg, Caribou reveals he is a Devil Fruit user, turning his arm into a gooey substance and smothering fake Sanji's face. The Fake Sogeking tries to shoot him, but the cannon ball ends up absorbed into his body, revealing that it is a Logia-type. Caribou orders his men to bury the imposters alive while he excitedly announces that he managed to confirm the real Straw Hats location. Back in Grove 46, Sentomaru reports back to his base, mentioning he managed to capture Demaro Black and most of Demalo's recruited pirates except for the Caribou Pirates and the other Straw Hat Imposters (sans Cocoa and fake Chopper), who somehow disappeared from the plaza.

He also comments on the Straw Hats' newfound strength after easily destroying the two pacifista he brought along with him and tells his base to call Marine Headquarters in the New World and warn them that the Straw Hats have finally revived. The scene then moves to a shore where Rayleigh is watching the ocean. Shakky joins him commenting on how quickly the Straw Hats left. She then asks if Rayleigh is recalling something. He jokingly comments "maybe" then remembers when he first met Roger who surprisingly looked very much like Luffy when he was younger, even wearing the same straw hat. Rayleigh then comments to Shakky that destiny is slowly taking shape and that Luffy has proven himself that he is worthy of wearing that certain Straw Hat. He also mentions that it would not be a bad idea to live for a bit longer. Meanwhile underwater, the Straw Hats marvel at site of the undersea world, one of which is the roots underneath Sabaody as well as the huge fish swimming around them. Robin then notices that ship's bubble shares the same characteristics as those on Sabaody. Nami confirms it, mentioning that anything strong enough to pass through the bubble will just go right through it, allowing them to fire the ships weapons if necessary. When Usopp asks what could break it, Nami answers that poking multiple holes in the bubble will indeed pop it, so they have to be careful not to let a Sea King bite into it or smash into a reef. Luffy remembers Hancock had fixed him food, so he shares his bentos with the crew while Usopp wonders why Hatchan is not guiding them like he promised two years ago. Franky says he need to tell the crew something. In the two years they were gone, both Hatchan and Duval protected the Thousand Sunny the best way they could but both were heavily wounded and Hatchan had to retire and head back to Fishman Island. A year after he left, the marines found out about Sunny and came try and capture it. However there was one more warrior who protected the ship: Bartholomew Kuma.
