CP9

Straw Hat Pirates at Enies Lobby, specifically against Luffy. Although he initially gained control of the battle using Rokushiki and his devil fruit, Blueno was outmatched when Luffy revealed his new Gear 2nd ability. With Gear 2nd, Luffy was able to easily keep up with Soru and heavily damaged the confident Blueno. Luffy then proceeds to defeat him as Blueno's last ditch effort, attempting to take Luffy's Gomu Gomu no Jet Bazooka with his Tekkai Gou, fails while he collapses shortly afterwards.

Justice Tower Scrambled Battle
The remaining members of CP9 faced the Straw Hats in battle. Franky defeated Fukurou after replenishing his cola supply. Kumadori was too powerful for Nami to defeat, but Chopper intervened. He was initially outmatched, but after resorting to Monster Chopper, he easily defeated Kumadori. Sanji, despite being stronger than Kalifa, was unable to defeat her because he could not kick a woman. Instead, Nami fought Kalifa and managed to defeat her. Sogeking was unable to defeat Jyabura, but Sanji fought on Usopp's behalf and defeated Jyabura. After being freed from his handcuffs to Sogeking, Zoro defeated Kaku. Luffy managed to defeat Lucci after a long and difficult battle, something none of the other Straw Hats could do. The defeated CP9 agents are left behind as the Buster Call begins to ravage the island. Spandam and his guards were shot down by Sogeking, Franky entered the fight and used Funkfreed's size against Spandam. Afterwards, Spandam's spine was snapped in half by Robin.

CP9's Independent Report
Blueno manages to protect the other CP9 members with his Air Door. Lucci, however, is badly in need of medical care. Spandam also sends Marines after the CP9 to blame them for the fall and defeat of Enies Lobby. CP9 manages to evade the Marines and thus are considered fugitives by the World Government. CP9 then crosses the sea train tracks to St. Poplar where they use their Devil Fruit Abilities to perform on the street in order to raise money to treat Lucci's injuries. Upon acquired the necessary funds, Rob Lucci was operated on and the other members of CP9 enjoyed normal activities such as shopping and sitting in the cafe. Lucci later regains consciousness, upright and staring solemnly at the sheets in front of him, with an elated Hattori at the windowsill. Lucci is subsequently discharged from the hospital, to the joy of his colleagues excluding Jyabura.

While bowling using their superhuman strength, Blueno notices trouble in the town. The Candy Pirates appear in the town causing problems for the citizens, so CP9 stop their bowling match and deal with the situation. Lucci kicks the captain of the Candy Pirates and another pirate while the rest get on the ship and beat the Candy Pirates up to the excitement and amazement of the townspeople. However, the townspeople are later horrified when Lucci kills the captain by crushing his skull. With all the negative attention, CP9 decide that they cannot stay in St. Poplar. A little girl offered Kalifa a flower of thanks which Kalifa accepted while Fukurou, Jyabura and Kumadori stood behind her terrified.

The CP9 agents set sail on the Candy Pirates' ship, and come to an island where children who will eventually become CP9 members are being trained. A group of Marines, commanded by Very Good, follow them there. CP9 then proceeds to the fight the marines.

Spandam is currently in the hospital in horrible shape from the beatings he took from Nico Robin. He receives a call from Rob Lucci warning Spandam that they will eventually return. After that, his father, Spandine, appears and Spandam calls him for help in a plan to destroy CP9. With that, CP9 depart on their ship.
