Tony Tony Chopper/History/Non-Canon

Chopper's Kingdom on the Island of Strange Animals
Following a lead from an old treasure map, the Straw Hats set sail for Crown Island, with everyone ready for a new adventure; except Chopper, who worries over every possible danger. While the others tease Chopper, the Going Merry suddenly begins shaking. Rushing above-deck, the Straw Hats find the sea erupting with dozens of massive geysers, one of which directly strikes the Merry and launches it high into the air. In midair, the crew can see the entirety of the island, and the crown-like ring of steam its surrounding geysers produce, but then the ship starts to fall and crash land on the island, accidentally Knocking Chopper off the ship in the process.

As Chopper is falling from the ship, he tries to grab onto the crow's nest, and he only succeeds in tearing off the Straw Hats' flag before vanishing into the island's forests. As he stumbles through the forest, he eventually ends up falling from the edge of a nearby cliff, and as he lands in the center of a mysterious circle, he screams in pain, which all of the nearby intelligent animals mistake as the cry of the king of the beasts. As they gather around Chopper, they all crown him as the new King of the Beasts, including Mobambi, the only human resident of the island, and his best friend, Karasuke, who tell Chopper that he is now the next king after the death of the previous king, the Kirin Lion.

The animals cheered, as Chopper was heaped under royal regalia (with the torn flag serving as a cape). Chopper tries to protest, but falters when faced with Mobambi's overjoyed praises - and pleas to help the island's injured, to which Chopper as a doctor, agrees to help with. As Chopper tends to the island's injured with Mobambi, he still insists on returning to the Straw Hats. On learning that the Straw Hats are pirates, Mobambi furiously begs Chopper to stay with "his people" as king; as a stunned Chopper listens to Mobambi recounting how his father, a naturalist, had been killed by a pirate years ago. Mobambi himself was forced to watch, and had survived just long enough to run aground on Crown Island, where - with only the wreck and a locket photograph to remember his father by, he was adopted and raised by the Kirin Lion. Despite feeling bad about Mobambi's past, Chopper still wanted to return to his friends, and simply continued to treat the injured while wondering where the others were.

Later, Mobambi and his friends hearing about possible invaders on the island, and they call on Chopper to fend off the approaching "invaders"; much to Chopper's dismay. At Mobambi's pleading, Chopper steels himself and tries to stand his ground, but nevertheless loses his nerve at the last second. An instant later, however, he is relieved to find the "invaders" are none other than his crewmates who had heard about the king of the beasts and were led to the mountain by a Bald Parrot. The Straw Hats are surprised to find out that Chopper is the new king. Chopper tells the animals that the Straw Hats are safe, and so he leads the Straw Hats over to a great feast so they can eat together. Mobambi demands what's so great about the Straw Hats, and when the animals hear that they are pirates and when Luffy asked for meat, the animals flee in terror thinking Luffy is going to eat them. Nami asks Karasuke about the treasure of Crown Island, but Usopp says that they should just grab Chopper and leave.

At that moment, there is a large blast, and so the Straw Hats and the strange animals run to see what it is. The then see that it is the true invaders of the island, a man named Battler and his men, Heaby and Hotdog, along with an army of Horn Eaters, the island's armored predators. Battler states that the power he is looking for is in the horns of the King of the Beasts. Battler demands that they tell him where the king is and starts playing his violin, so the Horn Eaters start charging. An angry Chopper leaps down and lands in front of Battler declaring himself as the King. Battler stops playing the violin, unconvinced by Chopper's words. Chopper tells him to stop attacking the animals and to call off the Horn Eaters, but Battler says he will only if Chopper beats him. Meanwhile, Sanji, Luffy, and Zoro are stuck behind a passageway, and Usopp and Nami fail to help Chopper fend Battler and Horn Eaters off. Desperate, Chopper then charges at the Horn Eaters, then turns to run, leading them away from the strange animals at the cliff above. He then runs off into the woods, with the Horn Eaters giving chase, as Luffy, Sanji and Zoro are finally free from the passage. With Sanji and Zoro going ahead to help, Luffy and the others console Mobami and the animals, before going off to help Chopper as well.

Chopper shifts between his three Points to flee from the Horn Eaters, but sees that they are quickly catching up, with Battler, Hotdog, and Heaby on their backs. Unfortunately for him, Chopper comes to a dead end and thinks about Hiriluk, then turns and finds Battler, Hotdog, and Heaby right behind him. As Hotdog punches Chopper, sending him flying, Chopper gets back up and runs towards him. Heaby then swings his chain sword at Chopper, but Chopper narrowly avoids each swing. As Sanji arrives and interrupts the two, he separates Chopper from Heaby and allows him to continue running. As he tries to run, Zoro also arrives, picking up Chopper, but when Hotdog attacks Chopper is sent flying again. Zoro stands up to Hotdog and tells Chopper to run for it, but as Chopper starts to run, Battler lands on him and grabs his horns. Luffy then bursts onto the scene, sending Battler flying with a Gomu Gomu no Rocket, as Usopp and Nami arrive as well to help Chopper with the Horn Eaters.

As Usopp and Chopper continue to run from the Horn Eaters, Nami calls to them from ahead. Usopp sees that Chopper is becoming tired, so he kicks Chopper to safety, as he and Nami decide to deal with Horn Eaters as Chopper escapes. With Sanji and Zoro dealing with Battlers men and Usopp and Nami dealing with the Horn Eaters, Luffy looks for Chopper, wondering where he went. As Chopper continues to go on the run, he is once again found by Battler, who begins to beat Chopper. As he knocks Chopper down, he is about to end it when Mobambi arrives, holding up the golden horn of the Kirin Lion. Mobambi runs, luring Battler away. Mobambi leaps across a chasm with a lava pit at the bottom, him and Battler plummeting into it. Karasuke dives down and catches Mobambi, flying upward, but Battler fires his chain weapon and wraps it around Karasuke's leg. Karasuke cannot support the weight, and all three of them fall toward the lava below, with Luffy showing up and saving them all by stretching out his arm and pulling them back up. Unfortunately, by the time Luffy finishes pulling them all up, Battler has managed to get the golden horns and devour them, becoming a giant golden beast with fiery horns on his head.

As Battler turns into a beast, Luffy leaps with a Gomu Gomu no Pistol, but is struck down. Battler leaps through the air and plows down toward him, sending Luffy flying back. Battler proceeds to take several vicious swings at Luffy, with Luffy barely able to keep up. Battler then gores Luffy with his horns, then sends Luffy flying, who barely manages to cling onto the edge of the cliff. Battler demands to know why Luffy continues to fight, and Luffy replies that it is for Chopper. Luffy's handhold crumbles, and he plummets down to the chasm below, causing Battler to laugh. As this happens, Chopper takes a piece of paper out of his hat, looking at a picture of Hiriluk's pirate flag. Chopper stands up to Battler, telling Battler that he will not forgive him, but Battler laughs it off. Chopper shifts to Heavy Point, then eats a Rumble Ball and begins battle with Battler. As Battler takes several hard swings at Chopper, Chopper shifts into Jumping Point and avoids them all. When he is struck, Chopper shifts to Guard Point, not taking a scratch. He then switches to Arm Point and uses Kokutei Roseo, striking Battler between the eyes. Battler is unaffected and slams Chopper to the ground, who returns to Brain Point.

Suddenly, Mobambi jumps into action and starts hitting Battler, but Battler tosses him away. Chopper is struck down as well, and Mobambi runs to Chopper, trying to help him up. After the revelation that Battler was responsible for the death of Mobambi's father, the two tried harder to fight against Battler, but were still struck down. Suddenly, there is a great rumbling, and all the animals from all over the island come charging toward the site of the battle. Battler strikes the ground with his horns, cracking it up so the animals cannot reach him. As Chopper, Mobambi, and several of the animals stand their ground against Battler, an angry Luffy rises, and lands a blow to Battler's face. Luffy then uses Gomu Gomu no Gatling Gun to strike Battler repeatedly in the chest, but Battler declares that it is no use. Luffy grabs Battler by the horns, lifting the great beast above his head, and smashes the horns in his hands. Battler quickly starts becoming a human again, and Luffy uses Gomu Gomu no Bazooka, sending Battler flying off into the distance, defeated at last.

With this, everyone cheers, and Mobambi thanks Luffy, but then starts to worry that he be exiled from the island for taking the golden horn. However, everyone called him a hero, and placed the King's crown upon his head. Despite Mobambi asking Chopper to stay, Chopper states that he is a pirate, then suddenly, there are more underwater eruptions, and a great bell begins to ring as the wind blows. The smoke around the island suddenly takes the shape of a golden crown, and the animals are shocked, declaring that the prophecy has come true, and that the heavens have acknowledged Mobambi as the new King. As Mobambi and Chopper say their tearful goodbyes, the next day the Straw Hats talk about the great party they had after the defeat of Battler. As they head toward their next adventure, Usopp jokes with Chopper about possibly seeing some monsters next, and Luffy happily yells that they will just keep moving, full steam ahead.

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 Kingdom. 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 no Mi abilities to reach and capture Vivi. Pell then shows up and 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.

Goat Island Arc
While being chased by the Marines, led by Moore and Minchey, Luffy and his crew get lost in the fog and discover an uncharted island. They find that the island is inhabited only by an old man named Zenny and a multitude of goats. They also find a partially constructed ship on the top of the island.

Because of his bad heart, Zenny probably only has three days to live. Hoping to make his last days good ones, the Straw Hat Pirates help him out and they learn about Zenny's past as a money lender and his dream of becoming a pirate and forming his own crew. But realizing that Zenny has outlived Chopper's predictions the Straw Hats decide that after helping him finish his pirate ship, they will leave the island. The Straw Hat Pirates help the old man out while hiding from the Marines and working to get his ship into the water.

With Luffy's help, Zenny and his goats were able to attack the Marines. The Straw Hat pirates then went forth to help him. They defeated Minchey and tied him up. Luffy, then, threw Minchey back on Captain Moore's ship, and Captain Moore allowed them to choose their battle location. Zenny decides to follow his dream and become a pirate, despite his age and they part ways. Luffy, then, pointed to the Marines a foggy area for battle location, which caused Captain Moore's ships to land in a shipwreck due to the rocks.

Baron Omatsuri and the Secret Island
On a calm day, the Straw Hats receive a message in a bottle advertising Omatsuri Island as a resort, promising spas and salons, good food, and many beautiful women, with Grand Line Pirates being especially welcome, the stronger the better. The crew are delighted at their luck, and Luffy decides that this is an opportunity they could not ignore. They set a course for the island.

When they reach the island, they see an uninhabited jungle but the crew follow strange sounds throughout the jungle, which leads them directly to the resort, and they are in awe by its dazzling rides and attractions. Soon, the owner of the island, Baron Omatsuri comes out on an elephant with a small talking flower sprouting from his shoulder to greet his guests. The crew notices the flower, and also notice that the dancers and performers, all have a small plants sprouting out of their heads as well. As the Baron welcomes the crew to his island and says they are welcome to enjoy all the delights he is offering, Luffy and the others are happy to hear this, but first he suggests that they prove their worth by taking part in a competition called the 'Trial of Hell, which he explains is similar to the Davy Back Fight.

Despite the crew being unsure whether or not to consider the trial, Luffy is filled with excitement by this challenge, saying that it might be fun, and that his friends are capable of handling any trial, officially excepting the proposal. As he accepts the proposal, the plaza they are in mechanically converts into an enormous round pool with a platform in the middle, as the first competition is goldfish catching, with the rules being that the winning team will be the one who catches the most goldfish in three minutes using only the net they are given, which is about three inches long and made of water-soluble tissue paper.

When Usopp volunteers to take on the challenge, he immediately changes his mind when he sees his opponent, Muchigoro and the massive goldfish that they have to catch, Rosario. As Nami, Sanji, Zoro and Luffy all try to catch the giant fish using their normal attacks, but only succeed in breaking the tiny net. Just as they decide that it's an impossible task, Muchigoro takes his turn. He reveals that he was hiding a net big enough to catch Rosario all along, much to the crew's fury. He calls Rosario into his net and flings him toward his prize bucket, with Robin intervening with her powers to bounce the fish back into the platform, where Chopper knocks him into own bucket using his Guard Point, just as the time limit ends.

Chopper, however, is dazed from his big transformation and stumbles into the sea. Luffy leaps in after him, forgetting that he cannot swim either. Sanji rescues both of them, but fails to notice that there are dozens of sunken pirate ships lying under the water. The Baron is furious at the Straw Hats for beating him, as well as insulting him and Muchigoro. He demands that they compete in another challenge. Nami had been hoping for a chance to relax at this island, and refuses on behalf of the rest. Luffy, however, overrules as before, having enjoyed the first trial and is looking forward to more. Nami, furious, tries to lead the crew back to the ship, but the forest seems to move around them and they become lost. Luffy, following them, continues to try to convince them to go back to the Trials. When they finally manage to leave the forest, they find themselves before the Baron again as he announces that they have arrived at the second trial - a complex game of ring toss, taking place between two teams of four people, each in two gondola-like waver boats. To win, a team must throw rings over every member of the other team. Due to being a devil fruit user, Chopper was forced to sit this trial out, and wait at the hotel with Robin and Luffy.

Chopper leaves as he finds a fruit to bite on and walks around, exploring the large mansion, unaware that the Baron is watching him. Chopper continues to explore with a fruit in his mouth. He could not help but think something was strange, since no one but themselves were in a large, beautiful resort on the island. He tells Robin that he will return right away, and goes outside. Chopper ventures out to the city streets, but they were completely deserted, just as he thought. The sun was beginning to set, but still, no one inhabited the buildings that filled the streets. It was a deadly silence. Chopper finally approaches rows and rows of tombstones and is awestruck at the great numbers. Behind him, a shadow creeps closer and closer, breaking the silence which surrounds him. Slowly turning around, Chopper screams, which surprisingly, scares the culprit as well, who was a pirate. They both scream in surprise, but the pirate man quickly tries to attack Chopper behind the tombstone, accusing him of being one of the Baron's men. He even goes as far as calling Chopper an otter - that is when Chopper overpowers him with his human form and scares the living daylights out of him. A young girl's voice calls out to him, calling him "Papa". Chopper is confused, but is eventually dragged down lower out of sight by "Papa". He begs for Chopper's forgiveness and begins to converse with him.



Finding out that Chopper is not one of the Baron's men, the man reveals his family's background as the Tearoom Pirates. He has a son and 2 daughters named Rick, Rosa, and Daisy, all which were cute and obedient to their father. He tells his story of coming out to Omatsuri Island and camping because they heard about its great resort. He found out it was all a lie, knowing that it was impossible to dip for a giant goldfish like Rosario. So then, they ran away. One of his daughters believes that her Papa is a very strong person, so with this in mind, he requests Chopper's assistance in pretending to be the one getting beat up while he acts strong in front of his daughter. In return, he will tell Chopper the secrets about the resort island. In the end, Rosa sees through his plan and reveals it to her younger gullible sister, Daisy.



Papa tells Chopper about who the Baron and his crewmates really are: pirates. He reveals to him an old bounty posted on a brick wall, which was discovered when he was lost on the island. In the photo are numbers of the Baron's men, with Baron Omatsuri at the center. It seems to be a very old piece of paper. Even the amount posted on the bounty was ripped, but one thing was certain, they were called the Red Arrows Pirates. The island known as Omatsuri Island does not exist, in reality it was a pirate island. The Baron's objectives were to lure pirates to the island to find the strongest pirates among them, thus the need for the trials. Chopper spots something strange about the poster, as in the poster, Baron seemed very young in the photo. As Chopper was about to unravel the mystery about him, a man in the shadows readies an arrow from afar. Daisy turns around and screams, but it was too late. Chopper turns around and is stricken with the arrow as the fireworks appear in the air. Out from the shadows Baron emerges, and looks into the poster which held the image of him, many years ago. He then takes Chopper prisoner and gives him to the Lily Carnation, where he is eventually absorbed into the monstrous plant in front of Luffy, becoming apart of it.



With Luffy and the other pirates trapped on the island banding together to stop Baron Omatsuri, the Lily Carnation takes it true form, with the entirety of the Straw Hats now assimilated into it and the Baron. Despite an uphill battle now ensuing, one of the pirates manages to fire an arrow into the Lily, critically injuring it in the process, causing all the inhabitants on the island to become lifeless again, and a shocked Baron to lose his connection with the Lily. With a now enraged Baron trying to finish everyone off, before he takes a step further, Luffy steps into the puddle of the Lily's innards and strikes him with a death-rendering punch, sending the Baron into oblivion, and ending the struggle.

With the Lily Carnation's destruction, everyone that was absorbed earlier returned, completely confused about what had happened to them in the first place. As the five of them emerge safe and sound, Luffy smiles in relief and closes his eyes. The Straw Hats spot him and quickly go to see him. With Nami calling out to him wondering what happened and how he could lay there and sleep in a place like this, Luffy couldn’t help but laugh, as the struggle on Omatsuri Island was finally over.

One Piece Film: Strong World
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.

Marine Rookie Arc


The Sanji Retrieval Team started to starve after Luffy wasted all their rations, and a starving Luffy tried to eat Chopper. However, they came across Fron Island, which Pekoms warned was home to a Marine base, but Chopper, Luffy, Nami, Brook, and Carrot headed there on the Shark Submerge III. When they reached the island, Brook scared some Marines into unconsciousness, and Chopper and the others stole their clothes. Chopper and Nami prepared to raid a food warehouse within the Marine base, but to their shock saw Luffy and Carrot going into a Marine cafeteria. Chopper and Nami eventually followed them into the cafeteria, where they were fed a warm meal by the staff. However, Carrot called out Nami's name extremely loudly, appalling her and Chopper. Nami was proposed to by a Marine named Zappa, and Chopper accompanied her as she ran out into the hall in shock. Luffy was discovered soon afterwards, and Chopper and Nami decided to run to the food warehouse so they could get food for the rest of their journey.



They made their way to the warehouse and broke into it. Later, Luffy and Carrot came and reunited with them, but they were confronted by the Marines Grount, Bonham, and Zappa. Chopper confronted Bonham, but was initially overwhelmed by the Marine's Rokushiki. However, Chopper managed to protect himself with Guard Point, and he managed to break through Bonham's Tekkai with Heavy Point, sending him flying into the food storage. However, a giant pot of water was knocked over in the others' fight with Zappa, causing the team to be washed outside in a flood.
