Enjoy this episode of One Piece 519 entitled "The Marines Move Out - The Target is the Straw Hat Crew".
Franky greets Robin at Grove 17, another straw hat member rejoining after two long years. (Brook is a famous super star and he will not be joining the One Piece crew on the new adventure.) Franky's body no longer looks human as Robin points out, but she is nevertheless happy to see him. Franky tells her where everyone is and how things are for the crew.
At Grove 47 Chopper mistakes Fakes Straw Hats for the real bunch and catches up to them. He is handled miserably as these guys don't recognize him and treat him like lost stuffed animal. Fake Luffy is wondering what or who knocked him out. He doesn't realize that it was Luffy's Haki.
Fake Zoro butts in telling Fake Luffy that Cocoa (fake Robin) got kidnapped. Fake Luffy is not touched by this and reflects on it by saying that it is her fault looking too much like real Robin. To this Chopper gets even more frantic as he doesn't get why Luffy would abandon his fellow comrades. Chopper runs away disappointed and sad and this is observed by Marines. They recognize him and mistake the fake straw hats for the real ones.
Nami and Ussop are out for shopping when they meet up with distressed Chopper. Confused even more Chopper doesn't figure out why Nami looks so much different than the one he just saw. He now remembers about Robin and starts telling them about Fake Luffy, when Ussop and Nami explain to him that the people he saw weren't Straw Hats but rather fake bunch pretending to be Straw Hats.
In the meantime, Fake Straw Hats realized who Chopper was. Fake Sanji and Zoro went to look for Chopper, but instead found real Luffy.
At Grove 46 pirates recruited by fake Straw Hats gather, but now they are being trailed by Marines.
