Episode of Arabasta: The Desert Princess and the Pirates
Vivi wakes up on the Going Merry to find Luffy and Usopp fishing with Karoo as bait, and she punishes them by bashing their heads together. They pull up a mysterious okama, who appears extremely grateful to be saved by pirates he does not know. The man reveals that he cannot swim because he ate the Mane Mane no Mi, which allows him to change himself into anyone he has touched the face of. He adds that he can also remember these faces, which allows him to take on the faces of those he touched before, showing several faces to the crew, one of which is Vivi's father Cobra, the king of Arabasta. The man then leaves as his crew arrives to pick him up, declaring the Straw Hats his friends despite not knowing them for long. As he leaves, he is called Mr. 2 Bon Kurei by his crew.

When Vivi realizes that the man was a member of Baroque Works and that he could turn into her father, she reveals that Arabasta is in a drought, and her father, King Nefertari Cobra had been framed for using Dance Powder, which forces rain onto the region it is used on at the expense of places downwind, for the capital. She states that the leader of Baroque Works is Crocodile, one of the Seven Warlords of the Sea, who is considered a hero in Arabasta for protecting the nation from pirates. In order to prove their identity should Mr. 2 transform into any of them, the crew each draw an X on their wrists and covers it with a bandage, which they will take off to prove their identity.

The crew reach Yuba, a ghost town that had once been a prosperous oasis before sandstorms ravaged it, causing many of the people to join the rebellion. They encounter an old man named Toto, who is the father of the rebellion's leader, Koza, a childhood friend of Vivi's. As the sun rises, Toto gives Luffy some of the water he dug up. During their travel, Luffy declares that he quits, saying that even if the rebels stop, the threat will continue as long as Crocodile is alive. He adds that Vivi is naïve to think that they can prevent everyone from dying in the battle, and he urges her to, rather than risk only her life, let them help her, which she agrees to. After this, the crew befriend a camel named Matsuge, and they begin to ride his Crab friend, Hasami. Vivi then thanks Luffy for helping her see the truth, and promises him a feast after they save the kingdom.

Crocodile ambushes them almost immediately, using his Suna Suna abilities to reach and capture Vivi. Pell attacks Crocodile and while he fails to injure him, manages to make him let go of Vivi. Crocodile's assistant, Miss All-Sunday uses her powers to ground Pell, then uses Clutch to severely wound him. Luffy intervenes, stretching out and throwing Vivi atop Hasami, staying behind to fight Crocodile.

As the rest of the crew go on to Alubarna without Luffy, Baroque Works' Officer Agents lie in wait, but the crew splits up as decoys for Vivi, allowing her to escape and try to stop the rebellion. Usopp and Chopper end up fighting together against Mr. 4, his dog Lassoo and his partner Miss Merry Christmas. Usopp and Chopper have difficulty dealing with Mr. 4 and his exploding baseballs, and the Officer Agents tell them that Luffy has been killed by Crocodile. Despite being heavily wounded after being struck by Mr. 4's four-ton bat, Usopp manages to trick Mr. 4 into hitting Miss Merry Christmas with his bat, then hits him with a hammer fired from a slingshot attached to Chopper's antlers. The two are knocked away from the fight by an exploding baseball detonating nearby, ending the battle.

After Luffy and Pell save Vivi, the rest of the crew get to regroup, and they attempt to retrace Crocodile's steps to find a bomb he placed in the city that will take everyone out, while Pell searches from the air. They discovers its location in the clock tower and is guarded by Mr. 7 and Miss Father's Day, who shoot Pell from the sky. The crew are left with less than one minute, and they work together to launch Vivi into the clock tower, where she easily defeats Mr. 7 and Miss Father's Day and cuts the fuse, only to discover that it's a time bomb and cannot be disarmed. Pell, however, shows at the last minute and carries the bomb high above Alubarna, sacrificing himself in the process. As the crew watch Vivi try to stop the fighting, the then see Crocodile fly through the sky and lands in the main square, defeated, knowing that their captain has won. As the fighting finally stops, Cobra then brings Luffy to his crew, meeting them for the first time. The crew then collapse from their injuries and rest in the palace as Vivi stays up, watching the rain.

Three days later, Luffy awakens from his coma, and the crew enjoys a feast for helping save the kingdom. As the eat, Chaka then arrives, informing them that Marine ships have come for the Straw Hats. Nami tells Vivi that she can come with them if she wants, and if she does, she must come to the shore at noon the next day. That night, Vivi wonders if she can truly continue her journey with the Straw Hats. The next day, Vivi, who is supposed to be giving a speech at the palace, instead proceeds to the shore, where the Straw Hats are waiting, initially believe that she would not come. She tells the Straw Hats that she can no longer travel with them, but asks if they will consider her a friend if they meet again. Luffy is about to say yes, but Nami tells him that her being associated with them will make her a criminal, and as they sail away on the Going Merry, the crew says goodbye by showing her the marks on their arms, while Vivi and Karoo does the same, happily saying their goodbyes.

On board the Thousand Sunny, the Straw Hats read news of attacks on East Blue. Luffy said they will return to East Blue to protect it when Shiki's ship appeared overhead. After warning him of the storm ahead, he came down to meet them. There he revealed 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 offered to take them there and uses his power on Sunny. Together the two ships traveled to the floating island seen before where Shiki suddenly kidnapped Nami. Chopper along with the others tried to rescue her, but by controlling the Thousand Sunny using his power, Shiki escaped them, as well as scattering them among the fragments of the island.



Zoro and Chopper ended up on a snow mountainscape. Upon riding around on a Mammoth Dense, they found and rescue a young girl, Xiao, and are lead to her village. She mistook Chopper for a talking Gorilla and momentarily fainted. Along the way they learned the large poisonous plants, called Daft Green, around the village emitted a stink so powerful that the animals stayed away from it. However, long term exposure to the plants is poisonous to humans, and Xiao's grandmother had fallen ill from it.

Xiao was outside looking for the cure, which is the IQ plant, and managed to find one, but Shiki had taken all the IQ plants for his experiments. They met up with Sanji and Usopp, also at the same village, where everyone appeared to have small wings on their arms, they learned that Shiki also took all the men and young women to his royal palace, leaving the village with only the very young and old with strict monitoring around the clock. When the rest of the crew showed at the village, Robin informed them of Shiki's plan. They learned there that Shiki is planning to let loose the animals on the island into East Blue in a gambit to force the surrender of the World Government. They also learned that to prove the power of the animals he is planning a demonstration using a village on the floating island.



Shiki then arrived sometime later and confronted the Straw Hats who were there. Chopper attacked with Kokutei Roseo Metel, landing multiple blows to Shiki's back, but only mildly hurt him. Despite some initial success in the others fending him off, Chopper and the Straw Hats were defeated, and Nami was coerced into rejoining Shiki by him agreeing to leave them, and her home town be. Usopp, the only remaining crew member conscious tried to stop her, but Shiki knocked him out.

Xiao reappeared and gave them the Dial Nami left them. Her mother, who earlier had expressed relief about the animals being sent to East Blue, apologized for saying how happy she was for Shiki leaving for East Blue. They then played the message, and after hearing only the first bit of it, Luffy was angered to the point that he will not listen to the rest (the rest of the crew did, however).

Back at Shiki's place, Nami is found to have in fact been attempting to blow up the plants protecting his palace, but was overcome by the poison. Shiki trapped her near the plants and headed off to meet the pirate captains gathering. The Straw Hats arrived at his palace and burst down the gates and made short work of the guards outside. While preparing a toast to the commencement of the operation, the Straw Hats marched into the main meeting room brandishing various firearms and a new wardrobe.



After a short confrontation, where Shiki called them simply a suicide squad, and revealed hundreds of men around them. They unload their firearms in the room, defeating most those gathered much to Shiki's dismay, then split up to defeat the rest. Luffy chased after Shiki, with the others helping fight off his minions and soldiers. Usopp and Chopper went off to try and rescue Nami. Chopper tracked her smell to the forest where she was slowly dying from the poisonous toxins. They found her but were hit by some explosives that destroyed the surrounding trees. They quickly grabbed Nami and escaped from the horde of giant animals that began their onslaught towards Shiki's fortress.

Usopp and Chopper began their search of the fortress for the science laboratory to retrieve the antidote. Shiki showed up and stops them, surrounding them with is devil fruit abilities. Luffy then appeared and stopped Shiki, as the two escaped with Nami in tow. They later found the laboratory and broke in, finding a group of IQ Plants. Dr Indigo appeared, laughing at them. Chopper says he recognized him as a scientist from the smell of chemicals on him. Usopp demanded him to hand over the antidote, but he refused. Zoro showed up and challenged Indigo for the antidote. He easily finished him off and retrieved the antidote for them.



When Nami woke up, Usopp consoled her, explaining that the antidote is working on her and everyone is fighting for her sake. Nami then ordered the two to backtrack to the royal palace. There, Usopp and Chopper threatened one of the remaining scientists to have Shiki move the island into a storm cloud. After Shiki is defeated by Luffy, Chopper along with the other Straw Hats escape using Thousand Sunny, using Shiki's pirate sail as a parachute. When Nami awoke some time later from Chopper's care, he tells her she recovered a lot quicker than he thought but asked her not to push herself too hard. He then tells everyone of Nami's recovery.

Caesar Retrieval Arc
A group of dark figures board the Thousand Sunny and attack the crew members, ceasing only at the command of a strange man named Breed, who captured Caesar. Law, Luffy, and Chopper pursued him in the Shark Submerge III, and sneaked into Breed's ship. Breed locked Caesar in a cell, and explained that Breed does not work for Doflamingo but is connected to the underworld. He also knew of Caesar's abilities as a scientist and kidnapped him in order for Caesar to help in creating his dream world. As Luffy's group arrived at the center of Breed's ship, which was designed like an aquarium, they once again were attacked by the mysterious figures, which were revealed to be animals, enslaved by Breed's ability. Luffy defeated their leader, one of the Kung Fu Dugong he had befriended in Arabasta. After the Straw Hats had left Arabasta, it had started a pirate group with other sea creatures to follow Luffy's dreams as well. Breed enslaved the group and was forcing them to do his bidding. Breed arrived and used his ability on Chopper, turning him into a pet under Breed's control. Chopper was ordered to destroy Luffy and Law, and, unable to control his body, he used a Rumble Ball to transform. When Luffy tried to prevent Law from attacking Chopper, Breed managed to attach collars to Luffy and Law as well. Law, Luffy, and the other pets were imprisoned next to Caesar.

Breed thought of Chopper as a cute pet and decided to dress him up in a girly princess dress. Chopper wore a pink hat with a red crown, a dark pink shoulders, a pink dress, four pink bows (first two on his antlers and the other two on his skirt), and little pink bloomers. Chopper hated this outfit while Luffy laughed.

Later, Chopper watched as Luffy and Law were forced to fight each other.
