One Piece Strong World The Movie English Subbed
The story begins at Marine HQ where Vice Admiral Garp and Fleet Admiral Sengoku witness Shiki’s ship floating in the sky overhead. Shiki uses a power to lift all the marine vessels into the sky, then drops them before departing, saying that this is a warning.
Next, Luffy is seen, currently on an island floating in the sky, and being chased by a crocodile like monster. This monster is overcome by another, which in turn battles another several times while Luffy watches until he finally briefly battles and defeats the final victor, a bear like creature, using his Gear 3rd. It is revealed that the various members of the Straw hat crew are separated around the floating island, Sanji with Ussop, Zoro with Chopper, and finally Robin, Franky, and Brook together who are all encountering similar monstrous animals.
Nami, meanwhile, is first shown swimming in a large swimming pool. Shiki and his henchmen enter, where it is revealed that she has been taken to this place against her will and the scene flashes back to several days earlier. On board Sunny Go, the Straw Hats read news of an attack on East Blue. Luffy says they will return to East Blue to protect it when Shiki’s ship appears overhead. Nami feels the weather changing and warns of a coming storm. Luffy calls out to Shiki ship, attempting to warn them, gaining Shiki’s attention. Shiki sends down a tone dial to record the warning. His own navigators initially disagree that a storm is approaching, but it does indeed appear and with Nami’s direction, both ships successfully escape it. Afterward, Shiki shoots his navigator, and comes down to the Sunny Go to meet Nami. There he reveals he has a Devil Fruit power to make any inanimate object he touches ignore gravity and float. After learning it was Nami that delivered the warning, and that they are headed to East Blue, Shiki offers to take them there and uses his power on Sunny Go. Together the two ships travel to the floating island seen before where Shiki suddenly kidnaps Nami. The others try to rescue her, but by controlling the Sunny Go using his power he escapes them, as well as scattering them among the fragments of the island.
Back in the present, Shiki asks Nami to become his navigator but she refuses. Dr. Indigo appears with an ‘evolved’ bird, called Biri, that can use electricity, demonstrating it to Shiki, but after being shocked by it, Shiki tosses it aside. It is explained that a plant here, called IQ, can cause animals to evolve very rabidly, making them very strong. Nami protects Biri, and the bird is left with her as Shiki and his men leave.
Elsewhere, Sanji and Ussop fight off various animals while Sanji searches for Robin and Nami, eventually falling from one island fragment to another, ending up in a lake just next to a village. Meanwhile Zoro and Chopper rescue a young girl, Xiao, and are lead to her village and are told about the large poisonous plants around the village that emit a sink so powerful that the animals stay away. However, long term exposure to the plants is poisonous to humans, and the girl’s grandmother has become ill by it. The girl was outside looking for the cure which is the IQ plant, but Shiki has taken all the IQ plant for his experiments. Sanji and Ussop, also at the same village, where everyone appears to have small wings on their arms, learn that Shiki also takes all the men and young women to his royal palace, leaving the village with only the very young and old. They soon after meet up with Zoro and Chopper. (more on from Wikipedia.org)
