One Piece

Nami and the conductors are rescued by Paulie when the Aqua Laguna floods the main station. A man hands Nami a letter he found from Sanji. It informs her that Usopp, Franky, and he are on board the train that had just departed. On board, he storms the cars. High up in the city, Nami speaks with Kokoro and spots Luffy, stuck in between two buildings, in the back streets where the Aqua Laguna will hit first.

Nami finally reaches Luffy and tells him that he needs to hurry before Robin reaches Enies Lobby. Chopper finds Zoro and hands him the Sandai Kitetsu so he can escape the chimney. Luffy pushes apart the buildings he was stuck between and Paulie grabs them all so they can escape the Aqua Laguna's massive wave.

Sanji fights his way through another train car and finds Usopp and Franky. Seeing how determined Luffy is to save Robin, Kokoro and Iceburg lends the Strawhat crew the use of another sea train, Rocket Man. The Franky Family shows up, pleading with Luffy to let them join them because they'll do anything for their leader.

The Rocket Man finally makes it out to sea. As the train connects with the tracks, Luffy has to rescue Chimney before she's thrown off by the wind. In the meanwhile, Iceburg has a flashback about when he finally met Franky again in Water Seven. With Luffy and Chimney safe in the train, Paulie tells his fellow carpenters who the real culprits were. The Strawhats, Franky Family, and Galley La Company form an alliance.

Luffy and Zoro perform a move that acts similar to a cannon and blasts a hole through the wall of the tidal wave ahead of them, opening up a channel for them to pass through. They miraculously pass through unscathed and the passengers rejoice. Sanji contacts the rest of the crew and fills them in on his current situation. Usopp separates from them but later, when Sanji and Franky are spotted, a man named Sogeking comes to their rescue.

Sogeking makes his grand entrance. Franky and Sanji aren't fooled by his costume but they try to humor him. They devise a plan first, then detach the last two cars and fight their way through the rest. Back in the Rocket Man, Luffy, Zoro, Nami, and Chopper get an outfit change; Nami shows off the weapon Usopp upgraded for her while he was still with them.

Kalifa updates the CP9 on the situation with Franky, Sanji, and Usopp. Sanji tells Franky and Usopp to go on without him so he can fight Wanze and his "Ramen Kenpo". Franky begins to fight Nero, CP9's "Weasel", and Sogeking meets with Robin.

Franky's fight with Nero continues. Nero discovers that Franky's weak spot is his back, so Franky lies down flat so he can't get to it. Nero demands that he fight seriously, so Franky gets up to perform his "Centaur" form. Sogeking talks with Robin and tells her that the crew knows about her reasons for leaving. Those on the Rocket Man encounter the discarded cars and Zoro slices them so they can pass.

Zoro clashes with "Ship Cutter" T-Bone. The fight is short and Zoro joins the crew again in the Rocket Man. On the Puffing Tom, Sanji beats Wanze beautiful, though Wanze thinks he's ruined his face. Franky finally gains the upper hand against Nero and defeats him. After beating their respective opponents, Franky and Sanji stand to fight against the other CP9.

After hiding under Robin's cloak for a few episodes, Sogeking finally shows himself. They stumble into the room with the CP9 and meet with Sanji and Franky. Sogeking produces a smokescreen. The four head into another car, detach it, and escape. It's not long before Blueno pulls their car back, though. Franky knocks down the wall so they can escape but ends up on the enemy car. Blueno opens a door then back in the Strawhat car.
