Nico Robin/History

Nightmare of the Buster Call
Nico Robin was born on the island of Ohara, and came from a family of archaeologists. Her mother, Nico Olvia, went out to sea to find the True History when Robin was two years old, leaving her in the care of Olvia's brother and his wife, Roji. While Robin's father was never revealed, Olvia stated that she will honor her husband's dream, she then left to study the poneglyphs. Robin later wandered into the Tree of Knowledge and was allowed to read the books held within on Clover's invitation.

Roji both verbally and physically abused Robin over menial actions. Roji made it obvious time and time again that Robin was not wanted; she was expected to keep out of sight and she was not allowed to participate in family celebrations. The powers of her Devil Fruit often freaked out or scared the other children, on top of that often she would overhear the conversations of parents telling their children to avoid her at all cost as well as other children calling her a demon. Her only friends were the scholars at "The Tree of Knowledge", with Professor Clover of the archeology lab, a friend of her mother, trying to take care of her.

At only eight years old, she aced an archeology exam and was officially inducted as a scholar. However, when she announced that she, like her mother, wanted to find out the true, unrecorded history of the world, she was reproved by Clover who told her she will get banned from the library if she continued to spy on the other scholars.

Robin ran off crying and headed to the northwest beach of Ohara, where she met the giant, Jaguar D. Saul, who was washed up on shore. The two became friends and Robin continued to visit him for the following four days, while he built his raft. After Saul found out he was on Ohara and figured out that Robin was Olvia's daughter, he informed Robin about the battleships that were on their way to Ohara to destroy due to the scholars studying the Poneglyph.

Nico Olvia had recently escaped off a Marine ship and returned to Ohara (due to Saul's efforts). She informed the archaeologists that her colleagues had been killed by the marines. She told them that the Marines were able to infer that Ohara was their homeland based on the items they possessed on the ship, and they were headed towards Ohara, likely to kill them. The archaeologists, however, refused to leave; they wished to continue to protect the tree and the knowledge they had worked so hard to research and procure. When Olvia was warned that CP9 was on shore, she rushed out of the Tree of Knowledge, running past her daughter without notice.

Robin arrived at the Tree of Knowledge, and asked Clover about her mother's whereabouts. As a wanted woman, Olvia wished to cut all ties with her daughter, so that Robin might not be associated with a criminal mother. Doing as Olvia wanted, Clover denied that Robin's mother was on the island, but Robin seemed skeptical. Clover quickly changed the topic and urged Robin to leave, and not to mention that she is an archaeologist, or she might be arrested too. Robin refused and CP9 bust into the Tree of Knowledge and began searching for the Poneglyphs.

Outside, agents warned the island's residents to move to the evacuation boat, or be destroyed. Olvia confronted Spandine, the director of CP9 at the time, but was quickly subdued by the brute force of his agents.

Back at the Tree of Knowledge, all of the archaeologists were arrested and taken outside the tree, and once again Clover urged Robin to escape, but she refused once again. Spandine and the rest of CP9 arrived with a gravely wounded Olvia, who instantly recognized her daughter once her name is spoken. CP9 found the Poneglyph in the basement of the tree, and Spandine sentenced the archaeologists to death by Buster Call. However, Clover began to speak out, talking to the Gorosei via Spandine's Den Den Mushi, stating his theory on why the government really wanted to keep the Void Century a secret. However, before Clover could reveal the name of the civilization he spoke of, he was shot point blank and mortally wounded.

Seeing that the battleships had already arrived, Saul rushed off to find Robin. As the attack on Ohara began, it was discovered that Robin also had the capacity to read Poneglyphs. As the bombardment began, Spandine and CP9 made their exit, Robin and Olvia reunited, and shortly afterwards, Saul arrived.

It was then revealed that Saul was a former vice admiral, and aided Nico Olvia with her escape. Olvia asked Saul to make sure that her daughter was taken safely off the island, and told Robin that she must continue to live. Robin begged to stay with her mother, but Olvia insisted on staying, as there was something more that she had to do.

Saul followed Olvia's wish and managed to reach the island's shore. But the Marine ships spotted him and opened fire. Seeing as he was carrying Robin, Saul put her down and retaliated in anger for almost hurting Robin, and destroyed several ships. Robin tried to make for the evacuation ship but trying to use her Hana Hana abilities to get aboard frightened the people on board, plus Spandine told them to not let her on since she claims she is an archaeologist, though this would be fortunate for Robin. Saul noticed Spandine and charged towards his ship for his foolishness, but Vice Admiral Kuzan (later known as Admiral Aokiji) prevented him from getting that far, challenging him.

The evacuation ship was destroyed by another vice admiral, Sakazuki, who did it as a precaution if any archaeologist had snuck aboard. This act disgusted both Saul and even Kuzan. Saul tried to get away with Robin but he was frozen by Kuzan's ice power. Before being completely encased, Saul encouraged Robin to escape and that her friends were out in the ocean waiting for her. His last act was to laugh as he is frozen, sticking to his philosophy to laugh from his heart even in bad times. As most of the beares of D. did when they met their demise.

Back at the Tree of Knowledge, Olvia, Clover and the other scholars had tossed out as many books into the ocean as they could so future generations could find them. They then realized there was nothing more they could do and stood in the tree as it burned around them. Olvia apologized to Robin for not leaving any parting words as a mother.

Robin ran to the raft that Saul built, only to be met by Kuzan. He told her that he was letting Robin go, since he was curious of why Saul risked his life for her. However, Kuzan warned her that he will be the first to come after Robin if she tried anything.

Robin then left on a boat guided by an ice path Kuzan set for her. Remembering Saul's words, she tried to laugh but wept as Ohara was burned to the ground, which left her as the only survivor.

Twenty Years on the Run
Robin was found by a ship heading northwest of West Blue and when she boarded it, somehow her bounty picture was taken. Spandine angrily explained to Sengoku that he tried to follow her, but his ship was caught on ice. For the World Government to capture her, he suggested putting a bounty on her head, and sent Marines and agents to hunt her down, spreading the lie that she sank six ships to cover up the truth.

The World Government labeled her the Demon of Ohara, they lied to the public that the Oharans were trying to find the Ancient Weapons to destroy the world, which was not what the Oharans were trying to do. Out of paranoia of what would become of her, the World Government let word out that she posed a threat and soon the world was brainwashed into thinking that Robin was trying to destroy the world. This negative gossip spread around the world, creating a half truth myth. Terms like "devil woman" were born along with the belief that her very existence is a sin and considered her a terror. Robin's innocent life was ruined and she grew up hating the Government for the crimes they committed against her.

Robin went to different people as the twenty years passed, all of whom tried to turn her in or kill her. Robin first encountered such attempts when she was taken in by an old farm lady, who she worked for and thought was kind. One night, the old farm lady told Robin that before they could eat she had visitors. The visitors turn out to be World Government agents attempting to kill her. The old farm lady was last seen yelling at the agents "Now give me the money! I turned her in for you" as she pulled the agents' clothes in anger. Next, Robin was then taken in by a couple, who she once again worked hard for. During the night, she overheard the people talking about turning Robin in, Robin then fled. After that, they angrily called Robin an unfortunate woman who betrayed their kindness.

She joined her first pirate crew at age 8. However, after the World Government caught up with her new crew, they assumed she had betrayed them. She fled before the pirates turned their anger against her. They even threw curses at her, calling her trouble. After that, Robin would often sit on a rock in pouring rain as a dog come to her begging for food. Robin apologized and said "dereshishi" for the last time. Robin then tried to help out in a shop, but the owner whacked her with a stick in anger, telling her that she was not allowed in.

When she turned sixteen years old, Robin joined an unknown organization, but it wasn't long before she betrayed the organization. At age twenty-three, she entered the Grand Line from the West Blue from the Red Line where Mariejois is located.

At age twenty-four, she joined the Baroque Works organization which was led by Crocodile, who needed her ability to read the poneglyphs, and managed to stay on long-term, safely hiding away from the World Government while employed in the organization.

Departure from Whiskey Peak
Robin first appeared as "Miss All Sunday" ("Miss Sunday" in the 4Kids English anime), agent and vice-president of the Baroque Works organization, at the end of the Whiskey Peak arc. She was responsible for blowing up Igaram's decoy ship, though Igaram survived, which apparently was her intention.

She met the Straw Hat Pirates and, after cryptically playing with them for a bit, offered them an Eternal Pose to Nanimonai Island. Luffy broke it instead, saying that he would not allow her to decide their destination. Princess Vivi revealed that it was Miss All Sunday who allowed her to discover the identity of Baroque Works' president, Crocodile.

War in Alabasta
Miss All Sunday made the necessary arrangements in order to organize the meeting between the remaining Officer Agents and the boss of the criminal organization Crocodile.

Finally the Officer Agents of the Baroque Works met up with Miss All Sunday and Crocodile in the basement of the Rain Dinners Casino, owned by Crocodile. They were told the goal of the Baroque Works, their final mission and their respective parts in overthrowing Alabasta. They were interrupted by Mr. 3, who told them that the Straw Hats and Vivi had escaped him during their time in Little Garden. He asked Crocodile for forgiveness, but is fed to his pet Bananawani (huge crocodiles with banana-shaped growths on their heads) instead. The Officer Agents all got pictures of Vivi and the Straw Hat crew (excluding Sanji) with the help of Bon Kurei's abilities and were given the order to hunt them down (excluding Chopper as Crocodile believed he was the Straw Hats pet).

Later Vivi was surrounded by Billions, but was saved by Pell, a guard of the king who flew to Rainbase after Carue's arrival in order to scout. Pell however was defeated by Miss All-Sunday and Vivi was taken to the Rain Dinners basement. There Crocodile told her his plan to overthrow Alabasta while it was being executed. Luffy, Nami, Usopp, Zoro, and Smoker all arrived at Rain Dinners, but they all were caught by a trap and thrown in a Seastone cage by Crocodile.

Later in the desert, during a battle against Luffy, Crocodile created a sandstorm and sent it off to Yuba, where Toto was, and explained that he was the one who was sending storms there every day. Luffy yelled for him to stop it but Crocodile impaled him with his hook during his distress then when he proved he's still alive, he left him in quicksand to die.

Luckily, Luffy was saved by Miss All-Sunday after Crocodile's departure and left Luffy in the hands of Pell, telling Pell that Luffy was responsible for the safe return of Vivi.

After the Baroque Works’ Officer Agents at the hands of the Straw Hat Pirates Vivi arrived at the palace. The war had already started. Vivi ordered the Royal Army to blow up the palace in order to get everyone's attention, but was stopped by Crocodile. The army, realizing what was happening, tried to enter the palace but they were stopped by Miss All-Sunday. Kohza also arrived at the scene, intending to demand Cobra's surrender, only to find out the truth of the situation.

Crocodile revealed that he is going to blow up the palace plaza, soon to be center point of battle, with a massive and powerful bomb. He also revealed his true intentions: to find the location of the secret ancient weapon Pluton, which is said to be buried in Alabasta.

Kohza wanted to warn the city but is stopped by Vivi, who stated that it will create a panic. The Royal Army raised the white flag, with Kohza in front, but he was shot down by a double agent in the Royal Army, provoking the rebels. A battle started on the palace plaza and Vivi watched in horror. Crocodile proceeded to throw Vivi off the palace wall, but she was saved by Luffy who came in flying on Pell's back. Vivi met the rest of the Straw Hats on the foot of the wall and went to search for the bomb with them and Pell.

Luffy challenged Crocodile for a second time but now he was aware that water is Crocodile’s weakness. While the fight continued, Miss All Sunday took the nails painfully out of Cobra's body and cuffed him with her powers to force the King to the location of Pluton. Meanwhile, a furious Crocodile recovered and ordered his partner to quickly depart.

Miss All-Sunday was confronted by Marines led by Tashigi. Having a more than personal enmity against Marines than other pirates, she yelled at them to get out of her way. Tashigi demanded she released Cobra, but Miss All Sunday was not going to take orders form those who directly took orders from the World Government. Tashigi is later informed by one of her men that Miss All Sunday was originally known as "Nico Robin", who received a bounty of 79,000,000 as a child because she was believed to have been responsible for the sinking of six warships. Visibly angered, Miss All Sunday easily dispatched the Marine grunts, and defeated Tashigi with her Devil Fruit ability.

Miss All-Sunday and King Cobra went in the hidden Grave of the Kings and found the Poneglyph. Crocodile soon arrived but did not get the information he wanted from the stone. He turned his back on Nico Robin and attacked her while she tried an assassination attempt of her own but failed.

Robin later gave the antidote to the poison in Crocodile's golden hook to Cobra, since Luffy was poisoned by it during his battle with Crocodile. After Cobra used it to save Luffy, Luffy managed to awaken long enough to grab Robin and Cobra and carried them out before the grave caved in.

Shortly after the Straw Hats' departure from Alabasta, Robin made herself known, having hid herself on board of the Going Merry before their departure. Claiming that she wanted to join the crew since Luffy saved her when she lost her will to live and he should take responsibility. Luffy accepted her offer to join the crew, but the rest (excluding Sanji) were suspicious of her. However, she managed to quickly win everyone's favor, except for Zoro, who remained wary of her.

Rumble in Jaya
Nami's Log Pose began pointing to the sky, after that, a big ship fell from sky and the crew found a map in the ship 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, while Robin herself decided to temporarily part from the crew and search for clues on her own. It was implied that she may have gotten into some kind of confrontation while gathering information, and used her powers to end the scuffle. The Straw Hats met with Montblanc Cricket on another part of Jaya; Cricket is a descendant of Montblanc Noland, an infamous "liar" who told of a gold city on Jaya, and Cricket was outcast for looking for artifacts of the gold city. He might have been 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 towards the location where the stream will erupt from the ocean. When Robin was able to catch sight of a South Bird she was able to quickly subdue it using her Devil Fruit powers. 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 was later refitted by Masira and Shoujou to be flight capable, and the Straw Hats caught a ride on the Knock-Up Stream for Skypiea.

Adventure in a Sky Island and Taking Down a God
They started  entering the Gate of Heaven. First they were recommended by an old woman to pay their extol, but even though they do not pay the old woman let them pass. As they were carried by a sky shrimp, they landed on a place that was surrounded by clouds. They met Conis, a Skypiean. As they talked, the White Berets interrupted them and labeled them as a criminal of illegal entrants. As Zoro, Nami, Chopper , and Robin board the ship, a shrimp suddenly carried them to the Sacrificial Altar. Zoro, Nami and Robin explored the land and they discovered it as a part of Jaya. They later came back the the Going Merry and were reunited with Luffy's group. That same evening, they discussed their plan of attack and had a feast with a bunch of local wolfs.

The next morning, Luffy's group set out to explore the iland. When a giant snake attacked them, Robin, Nami, Zoro and Chopper are separated, and all decided to go to the legendary city themselves hoping to meet each other there, although only Robin was going the right way. Robin defeated Yama, the chief of Enel's enforcers, angered by him destroying the ruins around her while trying to attack her. Saying he should treasure history more carefully. While looking for the Poneglyph, she met Enel himself and with a massive, powerful burst of lightning, he brought all the other combatants on Giant Jack crashing down to the city.

With Zoro and Nami (who were hiding) as the only known survivors of the game, there were only six combatants that had survived (Luffy was swallowed by the giant snake during that time), in front of the master of the game. Enel eliminated Gan Fall when he defiantly denounced him as God. Robin herself was struck down by lightning after trying to trick Enel into believing that if he destroyed Upper Yard, the Golden Bell would never be found, having anticipated that she would have knowledge of where it was and would try to use it against him.

When Luffy and a Shandian girl named Aisa escaped the snake (due to it being electrocuted by Enel), Robin regained consciousness, and told Luffy and Aisa of Enel's plan to destroy all of Skypiea, and gain the Golden Bell for himself. As Luffy charged towards the self-proclaimed god with Aisa on Pierre to give his location, Robin mustered up what strength she had to get the defeated Straw Hats to higher ground on Giant Jack in case Enel began his attack.

During the battle, Enel tricked Luffy, and temporarily prevented him from interfering with his plan by grafting a giant sphere of gold onto his arm and removing him from the ship. Enel then used his flying ship, Maxim to form thunderclouds over Skypiea, and commenced his plan by firing lightning bolts all over the land as it rises to search for the Golden Bell. Amazingly, Luffy returned to Giant Jack, and asked Robin to take care of Aisa, while he had unfinished business with Enel, charging up again.

Eventually, with Nami's help, the Straw Hats knocked over Giant Jack for Luffy with Nami riding her Waver to gain up to him, as he jumped towards the massive thundercloud Enel created, the Raigo, and discharged the electricity within it, causing it to explode and clear the sky. Luffy, with his final attack, knocked Enel through the Golden Bell, and ended the war between the Skypieans and the Shandians, with the bell and Enel collapsing.

After Luffy defeated Enel, Robin read the Poneglyph on the Golden Bell, learning about another ancient weapon, Poseidon, and sees Gol D. Roger's writing in the ancient script on the bell. She then concludes that the Rio Poneglyph is on Raftel. Seeing this, Robin became convinced that Luffy will be very important in the changing era of the world.

The Davy Back Fight
Robin 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 soon attacked by Captain Foxy and his subordinates, who challenged Luffy to a Davy Back Fight, a contest of pirates where the stakes were members of the crew.

She teamed up with Nami and Usopp. With only Nami's, and Porche's boat remaining, it was an all out war to the goal, but after Foxy exposes his Devil Fruit powers, Porche won and took Tony Tony Chopper from Luffy. Then the second round prepared to start.

She, together with the other Straw Hats, watched on the sidelines as Sanji and Zoro played the ball game, but were hampered by Foxy's blatant cheating and the crooked referee. But they managed to win, despite the constant cheating of the opposite team

Luffy and Foxy faced off in the final game: a battle of brawn aboard Foxy's ship. The Straw Hat crew watched aside as Luffy continued to battle Foxy with the odds not in his favor, and the fight continued inside Foxy's ship. Luffy managed to finally defeat Foxy by using his own ability against him. After getting back his crewmembers, the Straw Hats left in search of a shipwright.

After the Davy Back Fight arc, she was confronted by Aokiji, one of the three Admirals. Aokiji frightened Robin as he revealed to the crew a little of Robin's dark past, emphasizing that every organization she had joined has been wiped out, leaving her as the only survivor. She tried to retaliate and attacked him with her power, but he remained unharmed because the Hie Hie no Mi's Logia intangibility. The Admiral then froze Robin with his powers, and then tried to smash her frozen form, but she was taken away by her crew and she managed to survive, after having the ice encasing melted with hot water by her crew mates.

The incident, however left, her very upset, as even her captain got frozen by Aokiji, and even though he was saved too, the Archaeologist started to feel once more a disgrace for her companions.

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 the next island, Water 7. The crew traveled to Water 7 to cash in the gold from Skypiea and repair the ship, but soon found out that the Going Merry was beyond repair. Robin went shopping with Chopper, but she disappeared after a stranger wearing a mask whispered "CP9" to her.

Iceburg, the mayor of Water 7 and president of the Galley-La Company, was later nearly killed in an assassination attempt. He claimed that one of the assassins was Nico Robin, and assumed that the masked man who was with her was another member of the Straw Hat pirates. An announcement was made saying that the culprits of the assassination attempt were the Straw Hats, and that everybody should go and search for them. While the crew hid from angry residents, Sanji and Chopper discovered Robin and she told them what they had feared: she's responsible and she wanted to part ways.

The Straw Hats (still missing Sanji) rushed to Galley-La Company headquarters where Robin and CP9, an elite group of assassins from the World Government, were beginning a raid. In Iceburg's room, Robin and the mysterious man Iceburg saw before, told him that they've purposely placed the blame on the pirates. Their true aim was the Pluton blueprints passed down on to him by his mentor Tom. The assassins regrouped and were revealed to be Iceburg's own allies: Blueno the bartender, his secretary Kalifa, and two of his shipwrights Kaku and Rob Lucci.

The Straw Hat Pirates and Paulie broke into the room where they found Iceburg and CP9. Luffy and the others requested that Robin came back to the crew. She refused and told them that she could not 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 those remaining his Devil Fruit power.

When she boarded the Sea Train, the train was guarded. When it departed, Sogeking later appeared. Sogeking talked with Robin and told her that the crew knew about her reasons for leaving. After hiding under Robin's cloak, Sogeking showed himself. They stumbled into the room with CP9 and met with Sanji and Franky. Sogeking produced a smokescreen. The four headed into another car, detached it, and escaped. It's not long before Blueno pulled their car back, though. Franky knocked down the wall so that they could escape but ended up on the enemy car. Robin willingly followed Blueno into his improvised door and Sogeking and Sanji were left alone. For a while, Blueno explained a little of Robin's past involving the Buster Call. The CP9, Franky, and Robin finally reached Enies Lobby and disembarked.

Enies Lobby Arc
I WANT TO LIVE! TAKE ME OUT TO THE SEA WITH YOU! When Robin reveals her fears of being abandoned by the Straw Hats because of the danger of being close to her, Luffy ordered Sogeking to burn the World Government flag. This is Luffy's way of showing Robin that he and the Straw Hats would never abandon her if the World Government is her enemy, then they are the Straw Hats' enemy, too. Luffy then encouraged Robin to say that she wants to live, which she did, shouting out across Enies Lobby that she wanted to go to sea with them again. They proceeded to charge into the Tower of Justice facing off against CP9, to rescue her.

Robin in the meantime, suffered continuous torture at Spandam's hands, with him gloating that CP9 will crush the Straw Hats, and calling the Buster Call (accidentally) to give them a very slim chance of surviving. With Seastone handcuffs on her, Robin could do little to resist the physical punishment Spandam delivered (and once through his sword Funkfreed), and made her relive the painful memories of her home being annihilated, and her suffering of the past 20 years, all while revealing that the one who sent the Buster Call to Ohara, and started the painful two decades of her life of being hunted: Spandine, Spandam's father.

As Spandam laughed at Robin's suffering, the latter broke down in tears, reliving all that pain as she was being dragged across the Bridge of Hesitation, passing the arc on the bridge meant her fate would have been sealed after she passed the Gates of Justice, but Sogeking quickly fired gunpowder from another tower at Spandam, injuring him before he could get past the arc. Sogeking fired several gunpowder balls at the Marine soldiers, but they could not fire at him as the bullets do not cover the distance between them.

Robin, realizing who is helping, shed a tear of happiness, and Franky himself reappeared with the keys they recovered fighting CP9 and freed Robin. Happy that her crewmates returned and rescued her, Robin is told by Sogeking, via Franky's Den Den Mushi, that she is indeed Luffy's friend. Robin now free, proceeded to get revenge on Spandam by using her powers to slap him senseless with multiple arms. Despite the Buster Call being called in to deal with the Straw Hats, they all manage to escape successfully. Robin has apparently gotten over her past, as she joined the rest in fending off the Buster Call's attacks.

She also saved Luffy, who won his battle with Rob Lucci even after he was immobilized from repeated attacks at his internal organs by Lucci, by dropping him onto the Going Merry. After Luffy gets on board, he tries to thank her, but she uses her powers to place a hand over his mouth and thanks the whole crew for risking themselves for her. Seeing his refusal to give up his pursuit of the Straw Hats, herself in particular, Robin finally breaks Spandam's back with her Clutch technique to finish him off.

With the Going Merry, everyone has managed to escape Enies Lobby safely. However, after escaping, Iceburg arrives in a Galley-La ship just in time to pick up the Straw Hat Pirates as the Merry suddenly breaks apart. Luffy then gives the Going Merry a Viking funeral by burning it as the crew tearfully says goodbye.

Post-Enies Lobby Arc
Two days later, Robin is resting at Water 7 with her friends and those who helped her escape Enies Lobby. When Vice Admiral Garp arrives, Robin is surprised to learn that he is Luffy's grandfather. Robin then learns about Luffy's connection with Shanks when Garp was talking about the Yonko. After Garp mentions that Luffy's father is the revolutionary, Dragon, Robin explains more about him to Luffy since he apparently has no clue about it. Sometime after Garp left, a party is held at the Galley-la swimming pool. While standing alone and smiling, away from the celebration, she is greeted by a familiar voice. It is Aokiji, who is hiding behind the wall she is leaning against. He tells her that he let her go twenty years ago only because Saul had been his friend and that this whole Enies Lobby event was supposed to end everything after seeing her still floating in the world like a time bomb waiting to go off. Then Aokiji asks if she has found a home with the Straw Hats, and she replies that she has. Aokiji then questions as to whether she will show him if Saul was right, whether the destruction of Ohara was right or wrong. When she says she plans to, he left telling Robin to live strong and that Ohara is not fully destroyed and forgotten yet, presumably meaning that the memory and purpose of Ohara live on within her and left. Robin waited a few seconds, then ran to the other side of the wall, but all that evidenced that he was there was an X of ice.

A few days later, when the newspapers release the story of the Enies Lobby incident, the Franky Family and Galley-La shipwrights are removed from the report. Robin guesses Aokiji is behind it, but she does not tell anyone. Robin's bounty is increased to 80,000,000, with a new picture, a very small increase in comparison to the rest of the crew (with the exception of Chopper). After the Straw Hats lure Franky to the Thousand Sunny, Robin uses her powers to 'persuade' Franky to join the crew, by using her powers to squeeze his testicles until he agreed to join, even with everyone looking on in horror to what she was doing and Luffy telling her to stop as he wanted Franky to "still be a man" when he joined. She just replied that they are pirates, and that when they see "treasure", they should grab it and never let it go.

Adventure on Ghost Island
After sailing for some time on the Thousand Sunny, Robin and the rest of the crew came across a mysterious barrel floating in the ocean. Upon opening it, a flash shot up from it. Suspecting that it maybe a homing beacon of some sort, Robin asked the rest of the crew to get ready. After braving a storm that mysteriously came afterwards, Robin 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 through by chance initially accepted Luffy's offer to join the crew. This skeleton explained over dinner that he was once a pirate that ate the Yomi Yomi no Mi. Brook also explained that his shadow was stolen by someone. The later information seemed to spark an interest in Robin. Just as Brook was about to perform before Robin and the rest of the crew, a ghost appeared and some clanking sounds were heard. These sounds were caused by the gates of the island that suddenly appeared, Thriller Bark, closing. These events prompted Brook to head to the island before Robin and the rest of the Straw Hats' eyes.

With Luffy's resolve to go to the island, Robin decided to join also with the response that she likes thrills. After witnessing Franky's present to the Straw Hats, Robin and the rest of the Straw Hats decided to look for Nami, Usopp, and Chopper who had not returned. However before Robin and the rest could go to the island, they were stopped by an invisible thing. This thing licked her from bottom to top and left Robin and the rest baffled.

After the Thousand Sunny got caught in what was apparently a spider web, Robin and the rest descended to the island. There they met the Cerberus which Robin found cute. After Luffy tamed the beast, Robin and the rest met two more of the island's creatures.

Robin and the rest then came across some ghosts which she noted their difference with the rest of the other creatures on the island. She also noted the ghosts' strange ability to drain out one's will as she saw some pass through some of her traveling companions. After those who were affected by them recovered, Robin and the rest pressed forward. Robin and the rest later met with some Zombies and defeated them with a combo technique. The group then met with a old man who looked like a Zombie. The old man asked them to defeat Gekko Moriah who had stolen his shadow. Robin, upon hearing that name, explained to the group that Moriah was a Shichibukai with a former bounty higher than Luffy.

As Robin, Franky, and Luffy explored Hogback's Mansion, they were attacked by the Surprise Zombies in the dining room. After Luffy captures Buhichuck, it guides them deeper into the mansion into a trap. Luffy, Franky, and Robin are then forced to battle the General Zombies. Proving to be too many and too strong, they try to escape but Luffy is abducted and sealed in a coffin and taken away.



Before getting the chance to save him, Robin and Franky are blocked by a giant spider named Tararan. Franky destroyed the bridge they were on to escape from the situation and Robin reacted by creating wings out of hands. Though she stated she could only hold them for five seconds, it was enough for Franky to use his attack Strong Right to grab the entrance way from which the bridge had been attached to.

As they are pulled up to the opening, Brook suddenly falls from the sky. After Brook's fall, Tararan returns his attention to Franky and Robin once again. As Robin and Franky fight on, Robin finds herself trapped in a web formed by Spider Mice. Franky and Brook combine their efforts and defeat the Tararan and free Robin. After the battle Brook explains to Robin and Franky how Moriah creates Zombies and what their weakness is.

Later she helps Usopp and Chopper to defeat some zombies and escorts them back to the ship where they find Luffy, Zoro and Sanji. When Luffy asks if anyone objects to Brook joining the crew, Robin smiles and says Luffy would invite him even if they did. After explaining the situation to them Luffy tells the Straw Hats to prepare for a counterattack on Thriller Bark.

Robin was facing off against Doctor Hogback and Zombies, Jigoro, Inuppe, and Hogback's servant Cindry while Luffy makes his way to Moriah. When the zombies are defeated, she and Chopper try to finish off Hogback once and for all, until they are forced to flee when Oars attacks the mansion.

Robin helps the other members of the crew fight Oars. After that, she is seen knocked unconscious from Oars' attack. However, she recovers quickly along with the rest of the crew and proceeds to assist in bringing Oars down with her move Cien Fleur: Big Tree. However, Oars recovered and Gekko Moriah entered Oars' belly giving the giant greater strength than ever before.

Robin attempted to stop Moriah with her ability Ochenta Fleur: Cuatro Mano Hold but Moriah escaped the attack with the help of Doppleman, his shadow. Moriah then removes Robin's shadow from her body, leaving her unconscious, as he continues to operate Oars from within his stomach. She somehow awakens and helps Luffy and Brook get to the top of Thriller Bark by sprouting legs on the walls to climb on.

While she is almost disintegrated in the sunrise, her shadow returns in time for her to survive. Unfortunately, another Shichibukai, Bartholomew Kuma was also on Thriller Bark just receiving orders via Sengoku from the World Government to wipe out all witnesses, including the Straw Hat Pirates of Gekko Moriah's defeat by Monkey D. Luffy. After briefly dueling with Kuma, the Shichibukai gives the Straw Hats an ultimatum: Let him take Luffy (who has lost consciousness from the pain and fatigue he gained from fighting Moriah, and his body almost disintegrating), and the Straw Hats will be spared as they are not as much a threat to the World Government as Luffy is. They all refused his offer and Kuma released his Ursus Shock attack, knocking Robin, along with the rest of the Straw Hats and the Rolling Pirates, unconscious, but regained consciousness after Kuma left Thriller Bark.

Thanks to her power, she sprouted her ear to eardrop the conversation between Sanji and the Risky Brothers, and know about Zoro's story after Ursus Shock. After that, when Brook asked again if Luffy would honor his initial acceptance of joining the Straw Hats, Luffy replied yes. While all the other Straw Hats were shocked at how quickly he joined the crew, Robin just giggled. Once she and the rest of the crew finally left Thriller Bark, they held a toast to Brook, their new crewmember.

Strong World
The following events are unconfirmed to be part of the Canon story.

On board the Thousand Sunny, the Straw Hats read news of attacks on East Blue. Luffy says they will return to East Blue to protect it when Shiki's ship appears overhead. After warning him of the storm ahead, he comes down to meet them. There he reveals 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 offers to take them there and uses his power on Sunny. Together the two ships travel to the floating island seen before where Shiki suddenly kidnaps Nami. Robin along with the others try to rescue her, but by controlling the Thousand Sunny using his power, he escapes them, as well as scattering them among the fragments of the island.

Robin finds Franky and Brook and begin exploring the island they were flung to. They happen on the sunken ruins of a city submerged in a lake with trees taken root around the buildings. Upon entering they are attacked by the local wildlife. A horde of army ants pour out of an entrance and rush them. Franky prepares to fight but Robin reminds him that he is out of fuel. But then, a giant shark jumps out of the water to attack. The ants devour the shark before it is able to hit the water, and resume their attack. Brook steps in and cuts them all down.

Robin's group are later seen traveling across the desert on a motorcycle Franky made out of a giant Crayfish that he names Zarrey Davidson. As they approach Shiki's private village, the vehicle lurches back in fear almost throwing them off. Unable to ride further they walk the rest of the way.

Upon entering the village they find a large building where many hundreds of pirates are gathering, similarly protected by poison plants. They learn 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 learn that to prove the power of the animals he is planning a demonstration using a village on the floating island. Robin's group arrives shortly after, rejoin the rest of the crew after them suffering a heavy loss at the hands of Shiki.

Xiao reappears and gives them the Dial Nami left them. Her mother, who earlier had expressed relief about the animals being sent to East Blue, apologizes for saying how happy she was for Shiki leaving for East Blue. They then play the message, and after hearing only the first bit of it, Luffy is angered to the point that he will not listen to the rest (the rest of the crew does, 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 traps her near the plants and heads off to meet the pirate captains gathering. The Straw Hats arrive at his palace and burst down the gates and make short work of the guards outside. While preparing a toast to the commencement of the operation, the Straw Hats march into the main meeting room brandishing various firearms and a new wardrobe. After a short confrontation, where Shiki calls them simply a suicide squad, and reveals 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 chases after Shiki, with Robin and the others helping fight off his minions and hordes of animals who begin running wild in his fortress. Robin battles the giant butterfly Agehaguera, who she defeats by breakings its wings. However, she inhaled the pollen it spread in the air and collapses, only to be attacked right after by Shiki's minion, Scarlet.

Scarlet takes her up to a tall tower with her unable to move or fight back in its grip. It tries to plant a kiss on her appearently falling in love with her. Sanji enraged, quickly defeats him using Diable Jambe. Robin falls but Brook ends up receiving Robin's thanks when he catches her. Robin then helps Chopper move a heavy supply of dynamite into the laboratory to destroy Dr Indigo's biological weapons. After Shiki is defeated by Luffy, Robin along with the other Straw Hats escape using Thousand Sunny, using Shiki's pirate sail as a parachute. Robin is seen much later on the ship as Nami recovers.

Concludes unconfirmed section.

An Incident with the World Nobles
Journeying further into the Sabaody Archipelago, the Straw Hats are looking for a mechanic to coat their ship, The crew sees slavery firsthand, Robin talks about fishmen being treated as inferior in the past. When the rest of the crew arrive at the auctionhouse to rescue Keimi, Robin drops into the auction house using her Cien Fleur: Wing, and fights the guards with the rest of the crew.

Robin recognizes Trafalgar Law as a pirate when Luffy asks who he is. She prepares to disable Saint Shalulia before she can kill Keimi, but the Noble is stopped by Rayleigh's burst of "spirit". Robin escapes with Hachi, Rayleigh, Keimi and the rest of the crew to Shakky's Rip Off Bar, and hears Rayleigh tell of the truth about Gold Roger's fate.

Robin later questions Rayleigh as to what the Will of the D. and if they read the Rio Poneglyph, remembering when she noted Gol D. Roger writing a message in the same language. Rayleigh confirmed that they, the Roger Pirates, read the True History, but advised Robin that they may have misread it and that she herself may come to a different conclusion than they did. Rayleigh told them that they were mere pirates and had not had the intellect of the Oharan scholars or professor Clover, and said Roger simply had the ability to hear all things. Rayleigh seems to be fully aware of the details of the Ohara Incident, and mentioned it was a tragedy, but asked if Robin still wanted to hear what he had learned from the True History, to which she declined. Robin's first question about the Will of the D, however, was unanswered. Rayleigh decided to coat the Thousand Sunny free of charge, and because it would take at least three days to coat, he gave all the Straw Hats Vivre Cards to locate him.

Destruction of the Straw Hat Crew
After the Straw Hats departed Shakky's Rip Off Bar, they are confronted by someone who appears to be Bartholomew Kuma. Eventually, they are able to gain the upper hand on the Pacifista, and Robin helps defeat it by using her powers to form four huge arms to forcibly shut the Pacifista's mouth during a mouth blast attack, leaving it groggy before Nami and the Monster Trio (Sanji, Zoro and Luffy) seemingly deliver the finishing blows to the cyborg.

Later she follows Luffy and Chopper when they split up only to be intercepted by Sentomaru who sends Luffy flying, she later carries Luffy to safety when Chopper turned into his Monster Point. When Admiral Kizaru arrives and cripples Zoro, she tries to move him away from his attack but he just shifts his position and pins his body down.

Bartholomew Kuma also appears on Sabaody, teleporting the out of control Pacifista away and then all the Straw Hats to different locations one by one. Robin is the second to last one to be vanished when she was intercepted by Kuma while she was trying to escape.

Straw Hat Separation Adventure: Tequila Wolf
She landed on an island called Tequila Wolf, in the East Blue, where the enslaved inhabitants have been working on a bridge for the last 700 years. She is also shown having had her hands cuffed, indicating that she has to help build it. Robin asks why the Bridge is being built, and is told she has no need to know that.

She later appears to have escaped surveillance with a ring of stolen keys in her mouth, but apparently has yet to leave their domain. Eventually, she and the other slaves were freed by a group of revolutionaries who came to liberate them.

The revolutionaries reveal that they have been searching for her for 10 years because she was the only survivor from "The Nation who fought against the World, Ohara." Their leader, Dragon, told them to protect her from the World Government to the best of their abilities. The revolutionaries then offer Robin a meeting with Dragon. Robin declined as she does not need protection because she has her crew.

Robin then rides on a carriage which is going to the end of the bridge. While passing through a construction site from 300 years ago, Robin inquires about the bridge. A revolutionary informs her that the construction of the bridge is an order from the World Nobles. When Robin received a newspaper, she laughed and was glad that Luffy was alright. When asked if there was something interesting written, she agreed and smiled. While reading the article of Luffy infiltrating and praying at Marineford, she states "roger" with a smile as she always does when her captain makes an order.

She changed her mind about going to Baltigo with them. She said that if she had known there were people this kind in the world that she would have come to them sooner. The revolutionaries said that they did not know she was working under Crocodile. She responded that she was glad things worked out the way they did. She then has a flashback to her life on the run as a child and to the events of Enies Lobby.

When the revolutionaries invited her inside to be out of the cold, she said that as a pirate, she could not trust revolutionaries too easily and that it would not be wise to accept an invitation to a room where she would not have an escape route. As the revolutionaries were bringing her food and warm blankets, she wonders if she could become stronger by turning herself over to the revolution with Dragon, blushing and giggling at the idea. She then realizes that she has never thought of becoming stronger for someone else before now.

Straw Hat Reunion
Robin returned to Sabaody Archipelago in secret, the reason for this is currently unknown. She has pulled her hair back, revealing more of her forehead and is wearing sunglasses and a long skirt. People are chasing her for unknown reasons. She is seen wondering if she lost her pursuers while reading two posters, one about Brook's concert tour and the other one about the Impostor Straw Hat Pirates recruiting new members. She seemed confused by both articles.

Later, when the Fake Robin is captured by her pursuers and they report to an unknown source on a den den mushi that they "have arrested Nico Robin", Robin shows no signs of surprise, saying she has to hurry while wondering if everyone else had made it back.

She then returns to the Thousand Sunny at GR 17 where she meets and gets reacquainted with Franky. She comments that Franky has not changed (in terms of personality) and makes a joke at the fact that he can no longer be considered "human". Robin was then reunited with Nami, Usopp, and Chopper when they arrived at the Thousand Sunny.

When the Thousand Sunny arrives at Grove 42, Chopper and a giant bird brought Luffy, Zoro, and Sanji to the ship. When Boa Hancock intercepts a Marine ship, Robin tells the crew about her. With the Marines held back by the Straw Hats' new allies, the crew submerged and head for Fishman Island.

Undersea Voyage
As the ship descends, the crew marvels at the underwater sights. When Sanji is propelled out by a massive nosebleed and dragged back in the bubble by Luffy, she deduces that the coating has the same properties as the bubbles in Saboady Archipelago. Usopp scolds her for analysing the coating at the wrong time as Sanji's nosebleed is a more pressing issue. The crew then decides to have lunch while Franky explains how Kuma kept the ship safe for two years. As they ponder Kuma's intentions, the shadow of Caribou's ship is seen following them.

As the Thousand Sunny descends even further the Straw Hats marvel at how deep they are and how dark it is. With the help of a seacow, the Caribou Pirates catch up with the Straw Hats. Caribou quickly sets foot on the Thousand Sunny. Before his crew can follow, his seacow, which turns out to be Mohmoo, fled in fear after seeing Nami, Sanji, and Luffy, taking the rest of the Caribou Pirates and leaving Caribou alone on the ship. The Straw Hats then tie up Caribou as he begs for mercy.

With that settled, Robin helps Nami explain about the Sea Currents. She is then the one to spot the 'underwater waterfall' where the crew encounter the Kraken. Robin calmly comments that it is a rare sight and starts sketching it. Even though the Monster Trio leaves the ship using Barefoot Coating to fight the Kraken, the sea monster aims for the Thousand Sunny.

After Chopper blocks a tentacle with his Guard Point, Robin uses her Devil Fruit powers to prevent the Thousand Sunny from hitting the undersea mountain. The Monster Trio soon defeats the Kraken, but because they are not wearing life-lines, they got separated from Robin and the rest of the Straw Hats as the ship goes down the "underwater waterfall".

After reaching 7000 meters below the surface, the crew then encouters more sea monsters. When the crew reach the deep-sea volcanic region, they encouter an angler fish which attempts to eat the Thousand Sunny. Robin and the crew are saved by an Umibozu. The crew then encounters Van der Decken and the Flying Dutchman. Van der Dekken orders the Umibozu to punch the Thousand Sunny, but the giant is stopped by the newly-tamed Kraken. Luffy, Zoro, and Sanji are then reunited with the rest of the Straw Hats.

Before anything can happen, an underwater volcano starts to erupt. When the crew starts escaping from the volcano, Robin comments that Surume has an odd way of running. After jumping into the trench, she, along with Franky, notices the rocks falling toward the ship. When Zoro tries to cut them, Robin grabs him with her Devil Fruit powers, saying that the water pressure outside at this depth would kill him.

When the ship reaches the bottom of the trench, the crew finally sees Fishman Island. The crew then encounter a gang of sea monsters led by Hammond, who gives the crew two options: join the New Fishman Pirates or die. When Nami tells Franky her plan to get away from Hammond, Robin agrees that it is a good idea and the only way for them to make it out alive.

Discovering an Ancient History
Luffy rejects Hammond and the fishman prepares to attack. Franky activates Coup de Burst (using the rest of the oxygen contained within the coating's bubble) and the ship flies through the bubble surrounding Fishman Island. Upon entry, Robin realizes that the bubble is double-layered and that most ships would just fall through the air pocket between the layers. Upon successfully entering the second bubble, the Sunny then falls into a powerful current which separates the crew.

Robin remained with Nami and Franky after they entered Fishman Island. They went on their separate ways to do different things.

Robin decided to explore Fishman Island to study history. After defeating several Ammo Knights at a fish bus stop, she is seen riding on a fish bus heading to the Sea Forest. Robin learned that there might be a poneglyph in there. She soon meets Franky and informs him that she is searching for something and heads to the Sea Forest.

Robin eventually finds the poneglyph, hidden in the backwoods of the Sea Forest. She reads it easily, despite it being covered with moss and left to age. She comments that this poneglyph is different from the others, which has an apology letter written on it. She then wonders what the apology was for and asks about someone named Joy Boy.

She then returns to the location of the Thousand Sunny to interrupt a fight between Luffy and Jinbe with her new duplication technique. Later, when the group is discussing their attack strategy, Nami volunteers Robin and her self to get the keys to the royal family's shackles and swipe the tenryubito letter, respectively.

Battle for Fishman Island
Robin later goes to Gyoncorde Plaza with the rest of the Straw Hats and uses her ability to unlock the chains that bind Neptune and the princes. Robin and the crew then prepare to fight against the New Fishman Pirates. When Luffy unleashes a burst of Haoshoku Haki, Robin is surprised at his ability, though not unfamiliar with it. As the battle with the New Fishman Pirates commences, Robin defeats some of them with her Devil Fruit powers. She then use "Mil Fleur: Gigantesco Mano", summoning two giant legs and crush more of the pirates.

Later, when Hyouzou goes on a rampage, he charges at Robin. Zoro intercepts Hyouzou before he reaches her. When Jinbe sees Hammond's "Slave Tank" and how the New Fishman Pirates are treating their captives in the same way the World Nobles treat their slaves, he asks Robin to help and she agrees. Robin manages to get the key to the slaves' shackles and frees them as requested. Once freed, the slaves throw Hammond to the ground.

Hammond recovers and tries to capture Robin with a trawl net but it only caught a clone made from Robin's Hana Hana Fruit powers. Robin then uses Cuerpo Fleur to make a clone on Hammond's back and grab his neck, while she holds Hammond's legs with multiple arms and performs a Double Clutch move, breaking Hammond's back.

After all the leaders of the New Fishman Pirates have been defeated, the Straw Hats look into the sky as Luffy tries to destroy Noah. When the Sea Kings appear and stop Noah from falling, saving the ship and the island at the same time, everyone on Fishman Island celebrates. Princess Shirahoshi brings a wounded Luffy to the Straw Hats, since Chopper cannot move after using his Monster Point, Robin helps him move in order to save Luffy from blood loss.

An Important Secret Revealed and Departure
Afterwards, she attends the party at the palace in honor of their victory against the New Fishman Pirates and was seen drinking with the Minister of the Left.

Later, she wished to talk with Neptune in private about the Poneglyph she read and about Joy Boy. Neptune tells her that Joy Boy was a human who lived during the Void Century and talks about the promise Joy Boy made with the Mermaid Princess during the that time. He goes on about the importance of Noah and how Joy Boy was unable to keep his side of the deal and sent the Poneglyph with an apology on it instead. Robin then tells Neptune about the Poneglyph she read on Sky Island two years ago about Poseidon and states that its location is Fishman Island. She then asks if the Mermaid Princess of the Void Century had a name and realizes that Poseidon is the Mermaid Princess's name, so Shirahoshi has inherited the name and powers of the ancient weapon. Robin and Neptune agree to not talk about this as should other pirates or the World Government find out, they would hunt her down and try using her for themselves. Unfortunately for them, Caribou had listened to their entire conversation.

As the party ends, Robin is seen sitting with her friends and talking to Keimi. Later when Luffy brings the news about him declaring war on Big Mom, everyone was shocked while Robin merely smiles.

Afterwards, when the people of Fishman Island came to bid farewell to the Straw Hats, Robin was curious about what Neptune and Minister of the Right were whispering about. Later, she again seems glad when Luffy decides to choose the route to the most dangerous island. When Luffy promises Shirahoshi that he will take her to the surface the next time they meet, Robin and the other Straw Hats also promise Shirahoshi the same thing. After sailing away from Fishman Island, the Straw Hats cheer while they begin their journey to their next adventure.

On their way to New World, Straw Hats decides to fish some deep sea fishes for their welcoming party in New World. Later, Robin notices a White Storm which was sucking Sunny towards it and informed the crew about its dangers. Finally when the Straw Hats escaped the White Storm and enter the New World; Robin is seen among them remarking on the wild and strong winds on New World.

Arriving at Punk Hazard
Upon entering New World, the crew spots an island surrounded by a sea of flames. They then receive a distress call from someone who seems to be in trouble and supposedly resides on Punk Hazard Island. At first, Robin suspected that the call is a trap by the Marines, but Luffy decides to go to the island anyway. Later on, Luffy and a small group (including Robin, Zoro and Usopp) chosen by picking straws went to explore the island.

After disembarking, they sailed over the sea of flames beneath them on a cloud road Nami had made for them. As Usopp flusters and panics, she happily enjoys Sanji's lunch he made for them and playfully feeds Luffy some of it. As they approach near, they begin to feel the intense heat of the island and went deeper while observing the surroundings with Zoro and Robin wondering about the area being a former World Government base or locked up and closed off due to the extreme heat. She wonders why the log pose did not point to this place. As they begin to explore, Robin strips off her dress to an undershirt beneath due to the immense heat. Thinking back on the distress call remembering the caller mentioned feeling cold, with her wondering if there was a cold place on this island.

Later, they came across a mysterious Dragon that is supposedly capable of communicating with human. After the dragon is cleaved by Zoro, Luffy reveals a pair of legs stuck on the dragon and pulls them off only to see it was just a pair of legs to begin with. The group, except Robin and Zoro, are further shocked to see that the pair of legs can move on its own and talk, making the group realize that the voices they heard did not came from the dragon. The legs take off in pursuit of a Shichibukai.

After the group cuts up and eats the dragon meat and takes the rest with them, they continue their expedition. Luffy decides to play with the legs, placing them on his back and pretending to be a centaur. Robin comments on how vulgar Luffy is. Zoro then draws the group's attention to a remarkable sight: a lake separating the flaming half of the island from a frozen, mountainous region on the other half. Usopp then sights a humanoid figure with wings.

Luffy's group then receives a call from Brook, who informs them that the Sunny has been taken to the frozen side of the island and that the other Straw Hats went missing. After Luffy and Robin defeat two centaurs, the group decides to go to the frozen side of the island. To cross the lake, Usopp forms a boat from Pop Greens. While the group rides on the boat, the centaur that Luffy had just fought jumps after them and informs his boss that the pirates are heading his way. The four Straw Hats then see a group of centaurs waiting for them on the other side. The centaurs then fire their bazookas at the water around the boat, capsizing it and leaving Usopp and Zoro to hold up Luffy and Robin. Zoro moves to attack the centaurs, but is instead dragged underwater by sharks. The centaurs prepare to attack the Straw Hats again, but they are stopped by Brook, giving Luffy, Zoro, Robin, and Usopp enough time to escape the lake. After emerging from the freezing water, they plan on stealing coats from the centaurs. After defeating them and stealing their coats, the group uses Brownbeard as transportation to Vegapunk's former research facility. They soon arrive at the scene where Law and Smoker just fought.

After Luffy talks to Law, the group quickly gets away from the Marines and moves to the back side of the facility and meets up with Nami, Franky, Sanji, Chopper, and some of the children that were held prisoner in the research facility. The Straw Hats then tie up Brownbeard and bring each other up to speed on the current situation. After interrogating Brownbeard, they learn about a man known as Caesar Clown. Kin'emon later leaves the group to find his torso and Sanji, Brook, and Zoro go out to search for him. As Franky starts to adjust to Chopper's body, Robin tells him not to talk. Before long, several of the giant children start to feel pain, saying that they need candy usually given to them in order to make the pain go away. However, Chopper states that the candy contains a drug that the children became addicted to and Luffy's group learns that the children have been experiment on. The giant children start to go on a rampage, forcing Usopp to put them to sleep. Luffy's group then decide to help the children and find Caesar. The group also ties up the giant children so that they cannot destroy anything else. Luffy, Usopp, Franky, and Robin then leave Chopper and Nami to watch the children while they head to Caesar's lab. While they are gone, Luffy's group hears an explosion coming from the hideout and quickly turns back. When they return, the Yeti Cool Brothers open fire on them and escape with Nami in Franky's body.

Alliance with Law and Confrontation with Caesar Clown
Luffy and Franky go after the brothers and Robin and the rest are shocked that Franky turns into Monster Point and go on a rampage. After the Yeti Cool Brothers are defeated, Luffy, Franky, Nami, and Law return to the hideout. Robin and the rest are surprised that Luffy and Law formed an alliance. When Law returns Franky and Chopper to their bodies, Robin is pleased as she hates having Franky in Chopper's body. The Straw Hats and Law then form a plan to capture Caesar while helping the children.

Robin is later seen flying with Luffy and Franky towards Caesar's lab. While the other two crash into a Marine warship, Robin uses Wing to land safely on the ground. They all then prepare to capture Caesar Clown. In the ensuing fight against Caesar's centaurs and the G-5 Marines, Franky blasts the doors open. Before Robin's group enters the facility, pieces of the Slime start falling from the sky and attack anyone near them. Ceasar Clown soon reveals himself to both Luffy's group and the G-5 Marines.

Along with Franky, Robin then watches the battle between Luffy and Caesar. When Franky exclaims that Luffy is finally able to grab a Logia user, Robin compares Busoshoku Haki to seastone, saying that while that form of Haki allows the user to catch the real body of a Logia opponent, it does not negate the effects of the Logia ability like seastone does.

When Luffy was attacked by Caesar's Gas Tank, she screams out to Luffy and she was shocked when Luffy was attacked again by Gas Tank. She heaves a sigh of relief when Luffy manages to subdue Caesar after a lengthy battle. When Luffy suddenly faints, Robin and Franky wonder what is happening to him. Robin, Franky, Smoker, and Tashigi later fall into unconsciousness without Caesar even touching them.

She's then locked up in a cell with Luffy, Franky, Smoker, Tashigi, and Law. Robin asks Luffy if it feels nostalgic, as she and Crocodile locked Luffy and Smoker in a cage at Alabasta. While Clown is giving out his broadcast to the underworld brokers about his experiment with his chemical mass destruction weapon, Robin and the other captives just sit passively in the cell. After Smiley explodes and releases a poisonous cloud, the prisoners witness the destructive effects of the gas as some of Caesar's subordinates succumb to it. After explaining about his weapon of mass destruction, Caesar proceeds to move the cell outside of the facility where the prisoners will die.

Robin then watches as Law begins their escape plan, directing Franky to launch his Franky Fireball at the segregated battleship down below. Setting the wood alight, the smoke then rises up to the cage, allowing them to discreetly take action. Law quickly reveals that he had replaced some of the sea stone handcuffs with regular ones allowing for him to escape easily. After freeing Luffy and the others, Law uses his powers to move them into the laboratory. They then open the shutters, allowing everyone outside to escape the poison gas.

After the G-5 Marines plug up the hole made by Zoro and Kin'emon, they prepare to arrest the Straw Hat crew but are interupted by Law. Law tells everyone present about a way off the island through a door with "R Building 66". He then says that they all have only two hours to escape. As everyone departs with different objectives, Robin is seen standing next to Law as Luffy runs to find Caesar. Luffy tells her to go with Kin'emon's group, and she is later seen riding on Brownbeard's back. After one of Caesar's henchmen blows a hole on the wall of Building A with a cannon, the gas pours in. As the gate to the passageway to Building B closes, Robin and the others make haste to escape Building A. They, except for some of the Marines, manage to escape to the passageway before the gate shuts completely. They leave Tashigi and the Marines to mourn the loss of the ones who did not make it. The group continues on to Building B while riding on Brownbeard's back. After entering the building, the small dragon, after attacking Tashigi's group, begins to attack the Straw Hats, Kin'emon, and Brownbeard.

While Brook and Kin'emon argue on who should fight the dragon, Robin, Nami, and Usopp deal damage to it, leaving Brook and Kin'emon to deliver the finishing blow. The group then find Chopper (in Monster Point) trying to prevent the children from getting their candy. Regardless of his efforts, the children beat him down and run pass him when the Rumble Ball wears off. Robin, Kin'emon, Nami, Zoro, Usopp, and Brook quickly come to Chopper's aid and run after the children to the Biscuits Room, where Mocha is guarding a piece of candy. Robin attempts to hinder the children by using her Devil Fruit powers to creat giant hands as a barrier. This soon proves to be futile as the angry children continue going after Mocha. Monet then appears and tells Mocha to share the candy. Robin tells Usopp, Brook and Kin'emon to go find some kairoseki handcuffs and Momonosuke, and attempts to stop the children once again, only for Monet to stop her by stabbing her in the shoulder, telling her not to interfere. Zoro manages to stop Monet from landing more hits, though and tells Robin to leave her to him, as she is a Logia user.

Nami and Chopper then tend to Robin, but she assures them that her wound is only a cut. Monet tries to attack them when they attempt to run after the children, but Zoro quickly blocks her. After getting hit by Nami's Heat Egg, Monet dives into the snow and stops Robin, Nami, and Chopper from leaving by creating a wall to block their path. An enraged Monet suddenly ensnares Nami and Chopper and attempts to bite Chopper. Robin uses her Hana Hana no Mi abilities to shatter Monet. Zoro then cut down the snow barrier, allowing Robin, Nami, and Chopper to go after the children.

While Robin tries to help sedate the berserk children, she uses Cien Fleir: Dos Mano which creates two giant hands to pin down one of the children so that Chopper can give him a sedative. Despite Robin and Nami's best efforts, some of the children manage to get around them and catch Mocha. No longer able to run from the children, Mocha swallows the whole batch of candy as Robin, Nami, and Chopper watch in horror. While Mocha coughs up blood, Robin is happy to see Sanji and the G-5 Medical Team arrive to help. With their assistance, they are able to sedate the children.

While Chopper tends to Mocha's condition, Robin, Nami, Sanji, the children and the G-5 with them make haste to Building R. They later join up with Zoro and Tashigi. After Luffy defeats Caesar, Robin's group reunites with him. Once everyone reaches Building R safetly, they board a rail car and make their escape. Once they reach outside, they find Franky battling against Buffalo and Baby 5.

Aftermath
After the defeat of Buffalo and Baby 5 and the capture of Caesar Clown, everyone took a moment to rest and relax and they all have a feast together.

After the party ended, Robin and the rest of the Straw Hat pirates made their way to their ship to set sail to their next destination. While they made their way, the G-5 marines put up a banner to prevent the kids from seeing the Straw Hats while yelling things like Marines are justice and pirates are scum. The kids, however, said that they were the ones who saved them, while remembering all the Straw Hats did for them. The G-5 marines continue to speak ill of pirates and praise the marines, but Tashigi interrupts them and says they are a disgrace. The G-5 marines respond with saying that if they do not badmouth the pirates, they would come to admire and respect them. Eventually the marines lower their voices and banners to let the kids say their goodbyes, while Robin and the rest of the Straw Hats wave them goodbye, as they continue to make their way to their ship.

Robin and the Straw Hat pirates are later seen on a Seaslope, which are pretty common according to Law. A little while later, Luffy starts to explain that they formed alliance with the Heart Pirates to take down a Yonkou. Law then starts explaining about the operations and underworld deals of all the major pirates of the New World and that Doflamingo, also known as Joker, has the most influence in the underworld. Law continues on, saying that Doflamingo's biggest client is Kaido, which greatly shocks Kin’emon and Momonosuke. Law proceeds to explain the next goal of their plan which is to cut down Kaido’s forces as much as possible, specifically his army synthetic devil fruit users. Law also reveals that the current number of synthetic devil fruit users is about 500. Law assures the crew that the number won’t grow any time soon, due to the capture of Caesar. Law concludes by saying that the devil fruits are being made on their next destination, Dressrosa, and also warns the crew to not underestimate Doflamingo. Luffy asks if Kin’emon has business on Dressrosa and Kin’emon reveals that he has a comrade being held prisoner there.

Later that evening, Robin bathe together with Monosuke, making Sanji, Brook, and Kin'emon jealous. When they see him wrapped in her busom, Sanji, Brook, and Kinemon are completely infuriated until Nami reprimands them to behave. Nami offers Monosuke to sleep with her and Robin for the night, much to his delight. On the next morning, everyone read the news about Doflamingo abdicating his position as a Shichibukai as per Law's demands as well as his royalty of Dressrosa. They see that the newspaper also explains about Luffy and Law's alliance and the alliance between Kid, Hawkins, and Apoo. Law remains unconcerned with the other pirate alliance and then explains his next phase of his agenda to the crew.
