Long Summary
The fight has started. Luffy charges towards the enemies and punches them. Sanji and Zoro treat it as a competition between them, wanting to see who can defeat the most number of enemies, confusing Jimbe. A fishman tries to attack Jimbe but is stopped by Robin, who comments that Jimbe should just ignore them as this is their normal behaviour and Nami says that they haven't change one bit. Franky hops onto Thousand Sunny and comments that everyone is getting warmed up. Franky announces that it is time for them, prompting Usopp and Chopper to ask about the new weapons excitedly. Franky asks them to follow him and Usopp and Chopper say they have been anticipating this while running towards the ship. Nami asks them to wait up and Pappug follows hurriedly, not wanting to be left alone. Zoro and Sanji are running side by side, knocking down the enemies while arguing. When a fishman interrupts them, he gets beaten up by both Zoro and Sanji and flies towards Hody. The fishman says that they are too strong, angering Hody, who states that he has no need for soldiers who are afraid of stupid humans, and throws him away. Hody gives the order for Shirahoshi to be killed.

In Thousand Sunny, it is revealed that Franky has renovated the features by remodelling the the Soldier Dock System's channel 0 to create 5 and 6. Chopper rushes Franky to show them the new weapons which are kept in channel 4 and Franky pulls up the shutter, revealing the weapons. Chopper and Usopp squeal that it is cool while Nami and Papuug are speechless. Dosun is commanding the Artillery Unit to aim for Shirahoshi but Brook comments that he does not like this and jumps in front of Shirahoshi, playing his party music. His music causes the Artillery Unit to hallucinate and sees an amusement park. They dance and when Brook says to set off the fireworks, they use their weapons to shoot at the sky. Dosun stares at them, stunned, and Brook has already cut them using his technique, Quinto Tierce Fantasia. Another group charges towards Shirahoshi but is intercepted by Robin, who calls them brutes for ganging up on a weak woman. Robin uses Mil Fleurs, Gigantesco Mano, sprouting two gigantic legs which begin stomping on them. Usopp, Chopper, Nami and Pappug are cramped together in a small space and Chopper asks Franky how long more do they have to wait. Franky presses his noses, combs his hair, wears his goggles and says that it's all set. Nami comments that she is getting excited.

Daruma commands the Deadly Venom Squad to go forward and poison Robin's leg. At this moment, Franky calls out for them to hold it. Franky uses Soldier Dock System Channel 4 and burst out of the ship, riding on Black Rhino FR-U 4. Luffy is totally won over by it, calling it a cybike. Franky charges towards the Deadly Venom Squad, defeating them. Another fishman prepares to take on Franky with a spiked steel ball. The Soldier Dock System changes to channel 5 while the fishman swings his weapon and Franky is clenching his teeth, sweating. Another vehicle with a cannon shoots right at the fishman and Franky introduces it as the Channel 5, Brachio Tank 5. Chopper is crying while saying that he is Commander Chopper. Chopper spots enemies and tells Usopp the direction and commands them to fire, having fun in the process. Luffy runs alongside the vehicle and tells the commander that he is so cool. Zoro looks on in annoyance and tells Luffy to fight. The citizens states that the Straw Hat Pirates are so strong and begin to cheer them on again.

Hody calls Kraken out angrily and tells it to crush them all. The citizens are panicking and running away from Kraken's massive tentacles. Kraken jumps into the battlefield and attempts to flatten Brook. Chopper gives the command to retreat and Nami and Usopp show recognition at Kraken, surprising Pappug. Robin says that Kraken presence is unexpected and Luffy acknowledges it, calling it Surume. Luffy recalls the events when Surume was his pet and friend for a short while. Luffy requests to ride on it again while Surume rears up and seemingly crushes Luffy. However, while everyone looks, Luffy laughs as Surume picks him up, saying that it tickles, shocking the New Fishman Pirates. Surume gives Luffy a ride and obeys his command. Luffy tells Surume to stay near and protect Shirahoshi. Jimbe is impressed and says that he cannot believe that Luffy knew the Kraken. Shirahoshi thanks Surume and it blushes. Luffy comments that there are still a lot of enemies and urges the others go forward.
