Tony Tony Chopper/History

## Past

### No Disease is Incurable

Chopper was originally a reindeer with the slight oddity of a blue nose, which caused other reindeer, even his parents, to treat him as an outcast (always making him follow the herd from far back). When the young reindeer ate the Hito Hito no Mi, however, his herd ostracized him (and with the increase in intelligence granted by the fruit, he was now acutely aware of it), and he struck out on his own. Unfortunately for Chopper, his attempts at communicating with the humans on Drum Island proved disastrous, with the villagers mistaking him for a Yeti and shooting at him.

He was rescued by the quack Dr. Hiriluk, who named him and took him in as his friend and "assistant". Although his deeds were of dubious medical value, Hiriluk became Chopper's role-model. Hiriluk taught Chopper his philosophy on life (that all diseases could be cured) and his strong faith in the Jolly Roger as a symbol of strength against all odds. The two went from house to house, administering their "cures" in a country where all doctors not sanctioned by King Wapol were banned.

When Hiriluk's health worsened, Chopper was left in the cold again as the old man did not want Chopper to watch him die. Once Chopper found out what had happened, however, he vowed to find a cure for his mentor, his one, and only friend. He soon found the cure he was looking for: an Amiudake, a special kind of mushroom with skull-and-crossbones prominently displayed in the medical book (although unaware of what that sign meant medically due to Hiriluk's praising of pirates and the Jolly Roger). Remembering what he overheard by some villagers that a "certain" type of mushroom can heal every illness, Chopper steals Hiriluk's favorite medical book to find the miracle mushroom. Chopper's arduous journey was a success, even though he risked his life and suffered many injuries, the worst of which occurred when during his journey into the wilderness, in order to get to the mushroom, which was growing atop a treacherous cliff, he had to cross through the territory of his old herd.

Though most of the herd stopped and stared at him with silent scorn, the leader, a vicious older male whose forehead was covered in scars from combat, wanted to kill him for returning after the herd had cast him out. He attacked Chopper in a rage of prejudice and spite, and Chopper was forced to fight back, willing himself to carry on and get the mushroom. Though Chopper knocked the leader aside, the reindeer got up and murderously attacked him from behind. Chopper engaged him in a fierce fight and won, allowing him to claim the Amiudake. However, he barely made it out the fight alive, coming back to Hiriluk very weakened, with a broken left antler, dragging a badly broken left leg, and covered in many bruises and bloodied wounds. Though Chopper made a complete recovery after Hiriluk treated his injuries, and reattaching his snapped antler with a metal brace, it was painful for Hiriluk to see how terribly battered his son had gotten simply for his behalf.

Hiriluk, overwhelmed with tears of gratitude, ate the mushroom to show his love and appreciation to Chopper, (despite knowing that it would end his life) but Chopper would later find out from Dr. Kureha that he had given Hiriluk a fatal dose of poison, Chopper calls her a liar but she assured him it was truth and further being kind was enough to save lives; you need actual medical skills and training or you won't be able to save anybody. Chopper realizing what he had done begins to sob uncontrollably as Kureha pity's the foolish reindeer. But Hiriluk was not to live much longer anyway as Kureha surmises that the quake doctor chose Drum Castle to be his grave; Chopper rushes out the door to castle after hearing this. Declaring that he had a wonderful life (in the 4kids dub he declares he is a doctor) and after thanking Chopper, he committed suicide by blowing himself up outside of Drum Castle with a failed potion (before being killed by the poison, for Chopper's sake). Chopper, who had arrived to try and save him, was so upset over Hiriluk's death that and so angry that Wapol was making fun of it that he went completely berserk and tried to attack him, losing all control and running toward Wapol with a terrifying beastly roar. Dalton, who had heard Hiriluk's last words and realized that the monster he called his son was trying to attack Wapol he then stopped him. He then, with tears in his eyes, told him that he apologized for those who mocked Hiriluk's death but that he could not beat Wapol if he could not beat him. Chopper was brought out of his rage and then began to tear up as well at these kind words. He went to Kureha, waving Hiriluk's Jolly Roger outside her house and sobbing heavily, begging her to teach him and vowing that he would become a great doctor.

As for Hiriluk's last wish, Kureha (the last remaining doctor not owned by King Wapol) took Chopper in and taught him "real" medicine for the next 6 years. Chopper worked as hard as he could, in order to become a doctor like his idol, Hiriluk. As Chopper's studies grew, he eventually developed the Rumble Ball which could modify the wavelengths in a Zoan Devil Fruit's transformation abilities, giving him four extra forms. However, during one experiment where he took three Rumble Balls at once, he inadvertently took on an uncontrollable 'monster' form that went on a rampage and nearly wiped out an entire village, though fortunately nobody was killed. Chopper woke up in one of Kureha's hospital beds, bandaged and having no memory of what happened once he had eaten the Rumble Balls. After getting a lecture from Kureha to be more careful and that this form posed a danger to his friends, foes, and even himself, he promised never to unleash his monster form again.

Following the Blackbeard Pirates' attack on Drum Island and Wapol and his forces cowardly fleeing, Chopper and Kureha would take up residence in the abandoned Drum Castle, coming down the mountain occasionally to seek out anyone in need of medical attention (although Kureha demanded extravagant payments for her services).

## Arabasta Saga

### Drum Island Arc

#### Meeting the Straw Hats

Chopper is first seen following Kureha when she visited Cocoa Weed. She noted inflammation in Tamachibi's limbs and diagnosed a bacterial infection in his bones. With the villagers infuriated by Kureha's exorbitant fee, Chopper prepared to fight them but Kureha told him not to attack. Kureha and Chopper left with the supplies and money back home.

Later, a tired Luffy (from having climbed the mountain) would appear, with Nami and Sanji, outside the castle, while he was looking for a doctor. When he was about to fall, Chopper saves him. Then he took them to Kureha to tell her the situation, where the two doctors analyze the situation of the three boys, and then take them inside, here Chopper seeing that the antibodies are giving some process, informs Kureha commenting that it could be the Kestia. After a while, he approaches Nami with some cut leaves, where he stands up, scaring him, where Chopper tries to hide, albeit in a bad way. Nami tells him not to try to hide anymore, only making the reindeer street and causing her to be confused as to what he is. After Kureha tells him to shut up, he runs out of the room, only to return when he was being chased by Luffy and Sanji who wanted to eat him, where he transforms into Heavy Pont and beats them both up, where he runs out of the castle in terror. Upon returning, he listens to the conversation as Luffy proposes to Kureha to join the crew, remembering what Hiriluk told him about the pirates, before running again when Luffy and Sanji saw him.

On the way, he arrives at Nami's room, who was going to close her door, where he tells her not to because she still has a fever, starting a conversation between the two, where Chopper can't hide his embarrassment at Nami's thanks. Nami. She finally asks him if they are pirates, which she confirms, where she asks him if she is interested in pirates, to which he worriedly denies. Nami offers him to come with them, so he can be the doctor to take care of her on the ship without having to stay there for three days. Chopper tells her no, asking if he's not afraid of her for being a strange reindeer, to which she says no. Here he is chased again by Sanji and Luffy.

When he manages to lose them, he sees them trying to close the front door because of the cold, where he, knowing that there was a nest with some birds, tells them to stop. However, the two do not listen to him, so he transforms into **Heavy Point**, breaking and throwing a railing towards them, and then explaining the situation. He then walks away in sadness after being called a monster by the two pirates, only to be chased by them again, where this time Luffy proposes that he join his crew. Soon, Chopper smelled the arrival of his old nemesis, Wapol.

#### Fall of the Drum Kingdom

Chopper and Kureha then head out to confront Wapol, who has come to reclaim his old castle. Here Chopper is amazed at how Luffy attacks Wapol with a springy punch, wondering how he is able to do that. Here Chopper transforms into Heavy Point, deciding to face Wapol and his men to protect Hiriluk's ideals. At that moment, Kuromarimo throws one of his hairballs at Kureha, making Chopper worried, however, Sanji intercepts it with his leg, surprising him. He then sees that Sanji can't get that furball out, so Kuromarimo throws more, where Chopper tries to help him; but, he flees when he finds out from Chess that these spheres are flammable and he was going to light them. There he decides to face the latter, only to be swallowed by Wapol, but manages to free himself thanks to the help of Luffy and Sanji.

When Wapol gets up, devours his two subordinates, turning into his ultimate form, he then fires a cannonball at Hiriluk's Jolly Roger, insulting her. To which Chopper, angry, pounces on him and decides to attack him, but remembers Hiriluk telling him not to hate humans, so he doesn't and tells Wapol to just leave without having to harm him; where the latter shoots Chopper with cannonballs, leaving him injured. There he witnesses how Luffy defends the flag that he wanted to defend so much.

Chopper witnesses the dialogue between Luffy and Wapol related to him about the flag, and is surprised how Luffy protected that flag despite not knowing whose it was. Where he remembers Hililuk's words, marveling at Luffy and seeing him as a true pirate. When Luffy goads him to do something about it, he decides to fight Chessmarimo, the fusion of Chess and Kuromarimo. As they taunt him that he has no one in the world, Luffy joins him telling him to fight alongside him, to which the reindeer agrees, saying he will defeat his opponent. Here he takes out a Rumble Ball preparing to fight.

Here Chessmarimo shoots two fire arrows at him, but he dodges by transforming into **Walk Point**, then he transforms into Heavy Point and claims that he is a human reindeer, but Chessmarimo yells that he is the same and that he knows everything about his three mutations, taking out four big hammers, attacking him with one, but Chopper dodges it. He then descends on the opponent transforming into **Guard Point**, whereupon he absorbs a blow from a hammer. The opponent is amazed, but he says he doesn't care, asking him if he thinks he can beat him just by changing his appearance. Therefore, he attacks him with his hammer, but Chopper changes shape again and destroys one of his weapons easily, where he explains the transformations. Chessmarimo then attacks him with another of his hammers, so Chopper fights back with **Arm Point**, destroying the weapon in the process. Chessmarimo, already irritated, wants to use his **Dobikkuri Marimo, Quatro Axe** to finish him off, where he is wounded in the arm. His fight continues where Chopper constantly dodges his attacks, while he was looking for his weak spot. When he finally manages to locate him, he uses **Jumping Point** and stands in front of him to defeat him with **Kokutei Roseo**. After that, he watches as Luffy defeats Wapol, sends him away, and saves the kingdom of Drum.

#### Joining the crew

However, he sees some people approaching so he tries to hide behind a tree, here he is recognized by Dalton. Right there he was seen by some of the townspeople, who see him and point their weapons at him, but he is defended by Dalton, only to run away when Ussop calls him a monster, whereupon he is chased by Luffy. When it's night, he still hears Luffy tell him to come with him, where Chopper thinks he would like it, but he can't leave. Then he approaches the Straw Hats, who were all gathered there, to tell them that he couldn't join them since he's a totally weird reindeer being like a monster and that even if he wanted to join them, he couldn't since he doesn't consider himself a human but a monster. He finally thanks them and that they can go back, to which Luffy tells him to shut up and come with them, to which Chopper finally agrees.

Soon after, he arrives at Kureha in the infirmary to inform her of his decision to become a pirate and that he wants to leave with Luffy's crew. Kureha yells at him not to be silly, as he can't leave her alone, plus there's no way a reindeer could venture into the sea and it would just end up dead, to which Chopper yells that he doesn't care. Despite that, Kureha still refuses to let him go, so she starts chasing him, throwing many knives at him. Leaving the castle he transforms into Walk Point and hitches onto Kureha's sleigh. Kureha yells at him as he leaves the castle that he is following a crazy fantasy as Hiriluk. Chopper believes that she is wrong because Hiriluk completed his investigation before he died. She then calls the Straw Hats and tells them to come up, whereupon they all go up, while he transports them up the cable car. Despite what she had said, she is beginning to doubt whether Hiriluk's investigation was a success or not. Chopper was given a send-off of gigantic proportions: Kureha had turned the snow into sakura blossoms, the very same that Hiriluk had researched over 30 years that would one day, cure the people of Drum of their "sickness of the heart," where Chopper starts crying.

Arriving at the crew ship, where the crew celebrates their entry. As Vivi tries to warm Karoo up, the latter tries to explain what happened, so Chopper translates what the duck says, surprising Vivi that he can understand animal language. At the end he toasts along with the others for his admission to the crew, preparing to live adventures.

### Arabasta Arc

#### War in Arabasta

The crew saw a Sea Cat as they neared Arabasta. Starving for food, they try to capture it but Vivi stopped them since it was considered a sacred animal. As they pass through a steam of water from an underwater volcano, Luffy and Usopp caught an okama while fishing. As they waited for his crew to catch up, he entertains them with his Devil Fruit ability to copy other people's appearances, one of which was Vivi's father. When the man's crew caught up, he was revealed to be Mr. 2 Bon Kurei of Baroque Works. Knowing his abilities, they made an 'X' mark on their left arms to know when he was posing as one of them.

The crew landed in Nanohana where they encountered Smoker and Tashigi. A powerful pirate named Portgas D. Ace appears, and is revealed to be Luffy's older brother. Ace fights Smoker while the Straw Hats run for their ship. Ace catches up to them and gave Luffy a Vivre Card before departing. They docked their ship near the once 'green city' of Erumalu where they see the extent of the country's suffering as Vivi explained how Baroque Works was using Dance Powder to cause it. After tackling some of the dangers in the desert, they reach Yuba where they meet Toto, a friend of the royal family. They find out that the Rebel Army has moved out of Yuba and headed to Katorea, and the rebel leader Koza, Toto's son and Vivi's childhood friend, is determined to attack.

The crew travels to the city of Rainbase to take down Crocodile and Baroque Works, but run afoul of Smoker and Tashigi. Luffy, Zoro, Nami, Usopp, and Smoker are trapped by Crocodile. Chopper distracts Crocodile while Sanji frees the rest of the crew, but find themselves trapped yet again. After escaping from Rain Dinners, Usopp and the crew together with Vivi crossed the desert to Alubarna, where the final battle will take place.

Crocodile, however, managed to catch Luffy, beginning the first round of their battle. The crew, excluding Luffy, proceeded to Alubarna. As they reached their destination, they split up to distract the Baroque Works agents to engage their battle separately. At first Chopper was paired with Sanji when the two were pursued by Mr. 4 and Miss Merry Christmas, until Sanji left to check up on Usopp and Chopper had to fight by himself for a short while until Usopp came to assist him. The battle of Usopp and Chopper vs. the Mr. 4 team then begins.

Things looked hopeless for Usopp and Chopper as they continued to suffer from every attack that the Mr. 4 team made. When Miss Merry Christmas told them that Luffy is dead, Usopp refused to believe it, claiming that Luffy will become the next Pirate King. When she laughed at this, Usopp told Chopper that a real man never lets his friend's dreams be laughed at and must fight for it no matter what. Albeit severely beaten and bruised, Usopp and Chopper finally defeated the Mr. 4 team.

Later, the Straw Hats hurried to locate the bomb before it went off. Vivi figured out where the bomb was, and had Usopp call the Straw Hats together with a flare. She found it inside of the clock tower, but the Mr. 7 pair of Baroque Works were there. Vivi defeats them but realized the bomb couldn't be stopped so easily. It had a timer, and right before it blew up, Pell showed up and took it into the atmosphere, where he sacrificed himself to save Alubarna.

The Rebel and Royal armies continued to fight even after the bomb went off. It isn't until it rained and Crocodile was revealed to be one behind the drought that they stopped. Tashigi and Smoker both are rewarded for taking on Crocodile, but neither one of them believed it was right since the Straw Hat pirates did all the work. Luffy rescued Nico Robin and Cobra from the collapsing tomb where he fought and defeated Crocodile. He was then brought to the palace to rest. When he awakened, a banquet is thrown for the pirates. They were then invited to enjoy the hot spring steam-room inside the palace.

Later that night, Mr. 2 Bon Kurei contacts them, telling them he prevented their ship from being taken by the Marines. The next day, the day of her speech, Vivi was to make a decision on whether or not she will stay with the crew. Meanwhile, Bon Kurei and his crew helped the Straw Hats escape from Hina so they could get to Vivi, who declined joining them for the sake of her country. Regardless, they all showed their 'X' mark to signify that they will still consider her as one of them. After escaping from the Marines, Robin (Ms. All Sunday) appeared from inside of the Straw Hats ship. She managed to persuade the crew to let her join since she has nowhere else to go.

## Sky Island Saga

### Jaya Arc

#### Rumble in Jaya

Nami's Log Pose began to point to the sky, after that, a big ship fell from sky and the crew found a map in of an island named "Skypiea" on a 200-year-old ship. They competed with the monkey-like Masira's salvage crew while they searched for more clues on how to get there. The Straw Hats decided to go to Jaya island to look for information on Skypiea. The Straw Hats met with Mont Blanc Cricket on another part of Jaya; Cricket is a descendant of Mont Blanc Noland, an infamous "liar" who told of a gold city on Jaya, and Cricket was cast out for looking for artifacts of the gold city. He might have be the only person who knows how to get to Skypiea.

Cricket explained how the Straw Hats can ride a dangerous vertical current called the Knock Up Stream to get to Skypiea. However, they first had to catch a South Bird to point them toward the point where the stream will erupt from the ocean. While the Straw Hats were looking for a South Bird, Bellamy and his crew attacked Cricket's house, and stole the gold artifacts he'd collected over the years from his salvage work. When the Straw Hats returned and see what happened, Luffy decided to take a side trip back to Mock Town. The Going Merry is refitted by Masira and Shoujou to be more flight capable, and the Straw Hats catch a ride on the Knock Up Stream for Skypiea.

### Skypiea Arc

#### Adventure in a Sky Island and Taking Down a God

They started from entering the Gate of Heaven. First they had been recommended by an old woman to pay their extol, but they didn't have to pay the old woman and she let them pass. As they were carried by a sky shrimp, they landed on a place that's surrounded by clouds. There they met Conis, a Skypiean. As their conversation about the waver continued, the White Berets interrupted them and labeled them as a criminal of illegal entrants. As Chopper along with Zoro, Nami, and Robin boarded the ship, the shrimp suddenly carried them, they tried to escape, but that was impossible because of the skyfish behind them. The shrimp left them in the Sacrificial Altar. Zoro, Nami, and Robin explored the land and left Chopper to guard the ship.

As he guarded the ship Shura, one of the priests suddenly appeared to eliminate him. He fought Shura with his ability but found himself no match for the priest. He whistled the whistle to call Gan Fall. As Gan Fall appeared, he fought Shura but in the end, Gan Fall is defeated. Gan Fall fell into the water surrounding the altar and Chopper jumped in to save him but failed due to him not being able to swim. Both Gan Fall and Chopper were saved from drowning by the giant South Birds. Chopper is then told by the birds that Gan Fall is the former god. As the crew reunited, he is seen healing Gan Fall. They spent a night on the ship to regain more energy.

The next morning, Chopper explored the island together with Luffy, Zoro, and Robin to search for the gold, but a giant python named Nola attacked them, causing the group to split up. After finding himself all alone, Chopper was caught in the cross fire between Enel's enforcers and Shandia. Chopper eventually found himself on the Ordeal of Swamp where Gedatsu, one of the priests was. He mustered up his strength and defeated Gedatsu. Confident on being on his own, Chopper proceeded to the Upper Yard, but he encounters Ohm, who defeated him. He later regained consciousness when Luffy finally rang the bell.

Later he was seen joining in the celebration. The next day, the crew has collected a large amount of gold from Nola´s body when a group of Skypieans arrive with Robin bringing a large gold post, but the rest of the Straw Hats mistake it for a large cannon and they start running to their ship. They manage to return to the Blue Sea with the help of Pagaya and Conis.

## Water 7 Saga

### Long Ring Long Land Arc

#### The Davy Back Fight

Chopper and company came across a mysterious pirate ship after trying to escape a giant wave. Soon, they arrived on an island inhabited by strange animals. The Going Merry was captured by the Foxy Pirates. After Tonjit re-united with his horse, they were attacked by Captain Foxy and his subordinates, who challenged Luffy in a Davy Back Fight, a contest of pirates where the stakes are members of the crew.

The first round of Davy Back Fight involved a race around the island with tiny boats. In the anime, Chopper was teamed up with Zoro, and their boat was eliminated immediately. With only Luffy, Nami, and Porche's boat remaining, it was an all out war to the goal, but after Foxy exposed his Devil Fruit powers, Porche won and took Tony Tony Chopper from the crew.

When Foxy decided to take Chopper after the first round, the "Donut Race," Chopper cried, saying that he only went out to sea because he knew that his crew would be the Straw Hats. Zoro lectured Chopper, telling him that he must be a man and that he is responsible for becoming a pirate.

Then the contest began with the second round. Without Chopper, Sanji and Zoro had to face the Foxy Pirates in a ball game, but were hampered by their blatant cheating and the crooked referee. The bickering rivals Sanji and Zoro managed to overcome the opposing team by working together. Luffy takes Chopper back. (In the anime, Luffy chose Shelly instead of Chopper.)

Luffy and Foxy faced off in the final game: a battle of brawn aboard Foxy's ship. The Straw Hat pirates watched from the side as Luffy continued to battle Foxy with the odds not in his favor, and the fight continued inside Foxy's ship. They had not seen the battle when they fight inside the ship. Luffy managed to finally defeat Foxy by using his own ability against him. After Foxy's defeat, the Straw Hats left in search for a shipwright.

### Water 7 Arc

#### Water 7: A Breaking Ship, a Breaking Crew

After the Going Merry narrowly escaped being hit by a "sea train," the crew met an old woman, Kokoro, and her granddaughter, Chimney. Kokoro gave Luffy a map to Water 7. When they arrived there, Chopper had lost Robin when they were out shopping.

Chopper, along Luffy, Sanji and Zoro followed Usopp's bloody trail to the Franky House where they found him passed out in front of the building. The four of them challenged the Franky Family only to find out that their real target, Franky himself, was gone and had taken the money with him.

After an argument between Luffy and Usopp broke down into a fight, ending with Usopp being greatly wounded by Luffy, Chopper attempted to go to his aid. Sanji tried to stop him, though, saying that Usopp asked for the duel, and getting healed by Chopper would only bring him shame. Despite Sanji's request, Chopper went to Usopp, leaving behind medical supplies as he tearfully ran back to ship.

The Straw Hats got themselves a hotel room. An incredibly high tide called the "Aqua Laguna" was coming and Chopper and Sanji rushed to warn Usopp. While the crew hid from angry residents, Sanji and Chopper discovered Robin and she told them what they've feared: she's responsible for Iceburg's assassination attempt and she wanted to part ways. Chopper reunited with the others without Sanji and they discussed what had happened. Luffy decided that in order to know the full truth, they had to catch Robin.

The Straw Hat Pirates and Paulie broke into the room where they found Iceburg and CP9. Luffy and the others requested that Robin comes back to the crew. She refused and told them that she cannot accomplish her "wish" if she were to stay with them. Robin turned to leave and CP9 tried to hold the pirates back. Robin successfully escaped and Lucci showed the remaining his "transformation," a result of his Devil Fruit. He quickly disposed of the crew and CP9 tied up Paulie and Iceburg, leaving them alone as the building burned down around them. Chopper escaped the burning building with Paulie and Iceburg on his back and collapses outside. Nami rushed to tell Chopper so they can could look for the rest of the crew.

Chopper found Zoro and handed him the Sandai Kitetsu so that he could can escape the chimney he got stuck in. Seeing how determined Luffy was to save Robin, Kokoro and Iceburg lend the Straw Hat crew the use of another sea train, Rocketman. The Franky Family showed up, pleading to Luffy to let them join them because they'd do anything for their leader. The Rocketman finally made it out to sea. Paulie told his fellow carpenters who the real culprits were. The Straw Hats, Franky Family, and Galley-La Company then formed an alliance.

They miraculously passed through Aqua Laguna unscathed and the passengers rejoiced. Sanji contacted the rest of the crew and filled them in on his current situation. Back in the Rocketman, Luffy, Zoro, Nami, and Chopper changed their outfits. Those on the Rocketman encountered the discarded train carts and Zoro sliced them so they can pass. Zoro also clashed with "Ship Cutter" T Bone. The fight was short and Zoro joined the crew again in the Rocketman.

Yokozuna the frog jumped onto the front of the train, knocking them from the rails. After Kokoro spoke with him, he joined the group. Luffy and the others finally caught up to Sanji, Usopp (currently disguised as Sogeking), and the rest of the Franky Family as they neared Enies Lobby. Paulie sat down with the group to talk about their plan. Luffy didn't bother to follow the plan, and proceeded to slingshot himself beyond the gates before the train stops.

### Enies Lobby Arc

#### Rescuing a Friend from Enies Lobby

As they proceeded to Enies Lobby, Chopper and crew managed to land on Oimo's back. They rode Sodom and Gommorah to reach the Courthouse. As they waited for the bridge to be activated, the Straw Hat´s lined up at the roof to convince Robin to accept their request saving her. When the bridge was not fully lowered, Kokoro helped by using the Rocketman. The train used the half lowered bridge as a ramp. Luffy his crew down as he jumped onto it.

After they crash-landed, Fukurou appeared and declared that a key is needed to unlock Robin's cuff. The crew decided to individually search for and fight an agent, leaving Luffy to handle Lucci whom Fukurou said was taking Robin to the Gates of Justice. Later, searching for agent, Chopper found Zoro and Sogeking being chased by Kaku and Jabra cuffed each other. He was sent to search for the number 2 key from the other agents.

He switched with Nami to fight Kumadori. However, he took the Rumble Ball too soon was unable to defeat the CP9 assassin before its effects wore off. His fight with Kumadori was then taken into the kitchen where Franky was battling Fukurou. Chopper managed to stall the fight by locking Kumadori in the refrigerator. When Franky asked him to get him some cola so he could beat Fukurou, Chopper hesitated due to his earlier experience with Franky, but eventually decided to help since they were currently on the same side. After accidentally giving him vegetable juice, then tea, Chopper got the cola Franky needed and watched him blow Fukurou through the wall with a single punch. After watching Franky defeat Fukurou, Chopper found himself fighting Kumadori again after the latter broke out of the refrigerator.

His three basic forms unable to hurt the agent, Chopper thought about taking another Rumble Ball in desperation, but knew that by eating a second Rumble Ball right after the first, it would cause side effects that took away his control over his forms. He eventually gave in and ate the second Rumble Ball, risking the unwanted of shuffling through the wrong forms just so he could access the immense fighting strength of **Arm Point**, despite the possibility that his erratic transformations would keep him from entering that form before the three-minute effects of the Rumble Ball were used up.

As his transformations did not work properly, he was initially beaten by his opponent, and upon finally transforming into the form he wanted right before the Rumble Ball wore off, his strongest attack in **Arm Point** only served to make Kumadori angry. Pinned down, helpless, and about to be delivered a mortal blow by Kumadori, Chopper had no options left but to eat one more Rumble Ball and access his forbidden form. After recalling the last time he took three Rumble Balls, he mentally apologized to Dr. Kurhea for being unable to keep his word. Hoping none of his friends would cross his path, he took a third Rumble Ball and took on his **Monster Point**. In this form, Chopper quickly overwhelmed and even terrified Kumadori, brutally attacking him until he was knocked out. Despite defeating Kumadori, he continued to go on a violent rampage, beating up Kumadori even further and then tearing his way out of the judicial tower with Kumadori in his right hand, who he threw far away into the crowd of World Government and Marines at Enies Lobby, who were shocked to see a top CP9 agent land before them in a bloody pulp. Chopper started scaling the tower and destroying many of its upper rooms, disrupting several fights going on with the rest of the crew and CP9 agents, who were all alarmed at his monstrous form. When Chopper threatened to cause harm to the crew, Franky was forced to shoot him with his **Coup de Vent** technique, which sent Chopper soaring into the sea in order to stop his Monster Point's violent rampaging and to change him back to normal by forcefully disabling his Devil Fruit powers with their one weakness. Chopper reverted back to his humanoid reindeer form, but did not regain consciousness, and Franky had to retrieve him from the water.

He was later carried away by Kokoro, along with most of the crew, as she swam out of a flooded underground passage in the Bridge of Hesitation while making an escape. Being dragged underwater while out cold, he inhaled too much water and choked in his sleep. When he woke up, he and his crew mates had been saved by Kokoro from drowning, who turned out to be a mermaid. As his crew mates defended their get away ship, he could not move his body because of the side effect of the overuse of the Rumble Ball.

With the help of the Going Merry, everyone managed to escape Enies Lobby safely. However, after escaping, Iceburg arrived in a Galley-La company ship in time to pick up the Straw Hat Pirates as the Merry suddenly broke apart. Luffy then gave the Going Merry a viking funeral by burning the ship as the crew tearfully said goodbye.

Two weeks after the events of Enies Lobby, Chopper received his first bounty of 50, he was given a low bounty because he was perceived to be the "pet" of the Straw Hats. Chopper was shocked and disappointed that his bounty is so small, since he believed he fought like a man.

When Monkey D. Garp attacked and Usopp tried to rejoin, Chopper was the only one who did not deny his attention.

## Thriller Bark Saga

### Thriller Bark Arc

#### Adventure on Ghost Island

After sailing for some time on the Thousand Sunny, Chopper and the rest of the crew came across a mysterious barrel floating on the ocean. Upon opening it, a flash shot up from it. After braving a storm that mysteriously came afterwards thanks to Nami and Franky, Chopper and the rest of the crew found themselves in the presence of a ghost ship.

This ship apparently belonged to a skeleton named Brook who initially accepted Luffy's offer to join the crew. Chopper along with Usopp were exceptionally afraid of the skeleton. Just as Brook was about to perform before Usopp and the rest of the crew after dinner, a ghost appeared, and a clanking noise was heard. These sounds were caused by the gates of the island that suddenly appeared, Thriller Bark, closing. This prompted Brook to head to the island before Chopper and the rest of the Straw Hats' eyes.

With Luffy's resolve to go to the island, to which Chopper could not do anything. With Usopp and Nami, he set out in the new 'mini-merry' ship to explore Thriller Bark. There, the three met the Cerberus, which chased them until they hid in a tree. Here the three met Hildon who decided to take them to met Dr. Hogback. This pleased Chopper as the doctor was renowned in the medical world.

After riding a carriage with Hildon through some woods filled with all sorts of stitched-up creatures, Chopper and his companions were left in the middle of a cemetery. There, they were attacked by some Zombies, and escaped into Hogback's mansion and met with the good doctor and his maid, Victoria Cindry. Over dinner, Chopper asked for the doctor's autograph and a chance to visit his laboratory. The former request was given to Chopper but the latter was not.

After dinner with the good doctor in which the three asked about Brook, Nami decided to take a bath. For this, Chopper and Usopp were put in charge of guarding her from intruders from the outside. In the middle of the bath however, Nami was attacked by an invisible thing. Luckily, Usopp and Chopper came in the bathroom and drove it away. Later after the incident in the bathroom, Chopper and his companions found out that the paintings and taxidermy in the dining room were all Zombies. Fortunately, the three escaped through a secret door before the Zombies could catch them.

Beyond the secret door, Chopper and his companions found themselves in a room filled with Cindry's pictures. Through a newspaper article that Nami found, the three learned that Cindry was an actress that died ten years ago. As they were about to leave, the three stumbled across a treasure chest. Inside however, was a horrific Jack in a box that frightened the three out of the room.

As the three were running through the hallways of the mansion from more painting Zombies, a mysterious bodyguard decided to chase them.

Eventually, Chopper along with Usopp and Nami hid inside the stuffed body of Kumashi to overhear Moria's plan for creating Oars, the strongest zombie. Eventually the trio were discovered and made a run for it, but were surrounded and attacked by a large group of Zombies. During the battle, Nami was captured by Absalom. Franky and Robin arrived just in time to finish off the zombies. After that the crew made its way back to the Thousand Sunny where they found Luffy, Zoro, and Sanji. After explaining the situation to them, Luffy ordered the Straw Hats to prepare for a counterattack on Thriller Bark.

When Robin and Chopper attacked Hogback in his laboratory, they found him protected by Jigoro, Inuppe, and Cindry. Chopper and Robin fought them, but were eventually forced into submission. Chopper announced his disgust and defiance by declaring Hogback was no longer a doctor to him. He explained that when Hogback told him he was using the zombies to investigate the difference between life and death, he admired him because he could help those who lost loved ones when death occurred, but when he found out his role in the zombies' resurrection, he was disgusted that he would go as far as to use them for personal benefit instead medical science, and is forcefully moving them despite their hearts not beating, making them puppets. This, Chopper explained is why he cannot accept the zombies as living creatures, and Hogback as a doctor.

Hogback laughed and insulted Chopper's ideals, declaring he brought new life to the zombies and they should be grateful for "reviving" them. He demonstrated their proof of being "alive" by kicking Cindry in the face and ordering her to lick the ground. He explained that the room that Chopper went into earlier was his room, and told him how he disappeared, and the truth behind Victoria Cindry and her death.

He explained that because of his medical genius, many flocked to him with the hopes he could help them or their loved ones. Eventually, he could not be bothered with that, and explained it was only for the money. Then, a beautiful and famous entertainer named Victoria Cindry became one of Hogback's patients. Hogback, like many other men, was smitten by her beauty and fell in love with her, but she told him she was already engaged. However, it was nothing compared to his eventual heartbreak when he found out Cindry lost her life when she fell from a stage. A depressed Hogback left his job and disappeared from public knowledge, but was discovered by Moria and became in his servitude in the promise that Cindry be brought to life.

Eventually, he stole Cindry's corpse and with medical surgery and Gecko Moria's Kage Kage no Mi ability, Cindry was brought back to life as a Zombie. Hogback declared although Cindry had a different personality, he cared only for her beauty and said she is and should be thankful for her resurrection, and thus ordered her to attack Chopper.

While Chopper refused to attack her, and merely restraining her, as she continued to assault him. Chopper pleaded to Cindry to stop and look at what she's become. While she calms down, Chopper asks to Robin to use her powers and feed her salt. However, she was prevented from doing so by Jigoro and Inuppe under Hogback's orders. Later, it soon became apparent that the two zombies could not get along and began to fight each other, just like Zoro and Sanji so Robin took advantage of Hogback's orders by forcefully closing his mouth, asking him to order herself and Chopper to "jump off the tower." When Robin released Hogback, he indeed did give this order, but it was mistakenly given to Jigoro and Inuppe and they followed suit.

Chopper decided to pummel Hogback, as the mad scientist desperately gave orders to Cindry to buy him time, but she miraculously started crying, and said she could not move. Just as the battle was turning in the Straw Hats' favor, with Chopper with Robin's help about to deliver the final move on Hogback, Oars demolished the wall and interrupted the fight. As Hogback pleaded for Cindry's help, she simply smiled, implying her soul temporarily returned to her, and leaves him and herself to their fate. Oars' rampage apparently lead him to crush both Hogback and Cindry.

Chopper joined the crew's battle against Oars, and although the battle was completely drastic, it became increasingly desperate when Moria used his ability to manipulate Oars' body, giving him an ability to stretch like his counterpart, Luffy. Despite to Oars' immunity to pain, Chopper discover that his weak spot is his right arm. It was discovered that Oars suffered a severe case of frostbite, due to wandering the Land of Ice with very little clothes on.

Chopper, Sanji, and Zoro continued their attacks towards Oars' right arm, taking advantage of Oars' inability to feel pain, and giving his right arm considerable damage (though not initially noticed by Oars); however, Chopper and Sanji were knocked out for these efforts. With the Straw Hats falling one by one, Luffy returned to save Nami and Usopp and with 100 shadows in him, Luffy strength had multiplied several times over becoming "Nightmare Luffy" and began pummeling the zombie giant, beating him severely, with Moria himself caught in the attack, before powering down.

Down, but far from out, Oars got up to do battle again. Fortunately, Nightmare Luffy's attack was more than enough time for the Straw Hats to recover. Luffy himself surprisingly got up despite having the exhausting process of 100 shadows in his body for ten minutes. Chopper concocted a plan to force Oars' back straightened to take the full force of Luffy's attack. With his arm broken, Oars could not counter as Luffy activates **Gear 3** smashing a **Gomu Gomu no Gigant Bazooka** to his face, breaking Oars' back.

However, Moria returned to consciousness, and used his ultimate technique **Shadows Asgard**, taking in all shadows in Thriller Bark, numbering to 1000 to finish off the Straw Hats once and for all. However, as Chopper witnessed, Luffy activated both **Gear 2** and **Gear 3** at the same time, and finally defeated Gecko Moria, releasing all the shadows. Nami then remembered Kuma is on this island and tells everyone.

Meanwhile, Kuma reported that Moria had failed to kill Luffy and is badly wounded, he was ordered to kill everyone on Thriller Bark and evacuate the wounded Moria. However, instead of outright killing everyone as his orders said he offered everyone a deal- let him kill Luffy (who cannot fight back now) and he would leave everyone alone. The Straw Hats and everyone else on the island told Kuma "no way" and he set off a bomb made out of air that knocked everybody unconscious.

However, before he could finish off Luffy, Zoro rose again and vowed he will not let Kuma touch him, Kuma offered to just kill Zoro then and attacks him, though Zoro survived. Zoro offered his head for Luffy's and Kuma decided to torture Zoro by giving him all the pain and suffering Luffy had endured during the battle. Kuma then left, praising Luffy for having such good friends.

Soon after, Chopper joined everyone in a celebratory party at Thriller Bark (save for Zoro, who was still recovering from his wounds) lead by Brook and his piano. Luffy finally revealed to Brook that he is friends with Brook's friend, Laboon. Brook stopped partying, cried, and revealed a Tone Dial which contained the last song the Rumbar Pirates ever performed together on it. Brook stated that since he has found new friends in Luffy and the others, he no longer needed the Dial and would give it to Laboon the next time they meet. Brook then asked if the Straw Hat crew invite is still good and Luffy says it is, Chopper joins the others in a shocked response.

Once he and the rest of the crew finally left Thriller Bark, they held a toast to Brook, their new crewmate.

### 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.

### Sabaody Archipelago Arc

After leaving Thriller Bark, Chopper assisted the other Straw Hats on their continued journey. He helped with the battle against Flying Fish Riders alongside the crew.

Afterwards, he arrived in the Sabaody Archipelago, where he joined in the initial group heading out on the island. He was treated to cotton candy by barmaid Shakuyaku and eventually dozed off alongside Brook after trying and failing to find the assisting Camie. Usopp later found him and Brook and was berated for relaxing instead of looking for Camie, and they were quickly taken aboard a Flying Fish with the Rosy Life Riders.

#### An Incident with the World Nobles

After they entered the Human Auctioning House, Camie had already been sold to World Noble Saint Charlos in an extravagant bid of 500,000,000. However, Luffy's Flying Fish burst in, and he quickly got off to rescue Camie. In former enemy Hatchan's attempt to restrain him, he inadvertently revealed he is a fish-man and was shot by Charlos Sei. An enraged Luffy responded by punching him in the face, and started an incident attracting several Marines to the Human Auctioning House. Luffy, along with his and the crews of two of the Eleven Supernovas, Eustass Kid and Trafalgar Law cleared the incoming masses of Marines, Chopper assisted them in battle, until he as well as the rest of the Straw Hats with the help of Duval's Rosy Life Riders, managed to escape.

#### Destruction of the Straw Hat Crew

Chopper heard Rayleigh's story with the others, but shortly after leaving, he and the others were confronted by a Pacifista. Chopper's **Kokutei Roseo Metel** attack did very little damage to the weapon's defenses, but the group managed to defeat it by combining their efforts. Unfortunately, they were soon confronted by a second Pacifista and Sentomaru, Dr. Vegapunk's bodyguard. Luffy ordered the crew to split up, and Chopper went with Luffy and Robin. Sentomaru intercepted Luffy and managed to wound him with unarmed attacks despite his rubber body.

Seeing his companions defeated, Chopper became desperate and used three Rumble Balls at once, although he had already used one against the marines outside the Human Auctioning House and another against the Pacifista, it transformed him into **Monster Point**. Monster Chopper then began attacking Sentomaru as Robin fled with Luffy. He turned his attention to Kuma who just had appeared and was vanished as a result.

### Straw Hat Separation Adventure: Torino Kingdom

Chopper landed in the Torino Kingdom, in the South Blue, where the natives wanted to cook him. As seen in the Straw Hat separation serial, Chopper was running for his life to avoid getting eaten. At some point, he managed to hide while the natives were fighting the giant birds on the island.

After some time on the island, Chopper managed to stop the war between the humans and birds, using his ability to talk to animals to translate for the natives. Afterwards, he left the island worried and wanting to heal Luffy's wounds after learning of his involvement in the war and Ace's death. He flew off the island on one of the birds, though at the same time a News Ku passed by, and after reading the paper Chopper was shocked by a recent article involving Luffy.

He stated that he understood why Luffy was praying at Marineford, and afterwards, he returned to the Torino Kingdom to become stronger. Since Chopper is uncomfortable with returning to the island sooner than expected, he wore a disguise called "Chopper Mask". However, the natives instantly recognized Chopper and the reindeer then threw away the disguise.

Chopper said that he wants to study the plants on the island and a native took him to the village library where he could do his research. Chopper then commented that the natives are not as primitive as he originally thought as he recalls them using mechanical weapons. Chopper then thought back to his early days, where he was called a monster and shunned by everyone. He realized that ever since he joined Luffy's crew, it did not matter what other people called him, and he promised to help Luffy no matter what.
