Nico Robin/Personality and Relationships

Personality
Through her heritage on the island of scholars, Nico Robin is an archaeologist and historian, who joins the Straw Hat pirates. She seeks the comfort and freedom to study the mysteries of the world. She is the quiet, reserved crew member, rarely showing emotions or having outburst of emotions (occasional exceptions being sweat drops, and when she cried out to Luffy and the Straw Hats from the Tower of Justice during the Enies Lobby arc), and as such, is the only crew member to have no face faults. Robin even appears calm at times towards her crew mates, often speaking ominously around them. She has a somewhat macabre side to her, and often points gross or morbid facts, usually to the disgust of Nami or Usopp.

Examples include:
 * When Luffy, Zoro and Sanji were exploring a galleon that had fallen from Skypiea and was eaten by a giant sea turtle, Robin says if they have been eaten along with the ship.
 * When Nami asks if Zoro was eaten by the skyshark, she says that the clouds would be turning red if he was.
 * When Nami is forced to swing on a rope past the skysharks, Robin says the height is about 50 meters and she would die if she fell.
 * Zoro and Nami return to the Going Merry in Skypiea but they cannot find Chopper, who was guarding the ship. Robin remarks that he may have been "shredded to pieces".
 * When Chopper is taken by the Foxy Pirates during a Davy Back Fight, Nami asks if Foxy is a collector of rare pets. Robin says, "Hopefully not a collector of rare pelts".
 * When the crew decide on the name "Thousand Sunny" for their new ship, Robin says that she was going to suggest the "Being of Darkness".
 * On Thriller Bark, she voluntarily investigates the Ghost Island with Luffy and Franky. She told Nami that she "likes thrills".
 * As Nami screams while testing the Mini-Merry II on Thriller Bark, Robin remarks that she may have been cursed by a ghost.
 * While the Strawhats are looking for Nami, Chopper and Usopp at the Ghost Island, Robin says that they are not even able to hear their voices anymore, wondering if they were strangled.
 * When they are attacked by the Cerberus on Thriller Bark, Robin says that she finds it "cute".
 * While searching for a way to reach Fishman Island in the shark submarine, Robin, Luffy and Brook encounter a giant sea monster that attacks them which resulted in Robin amusingly commenting on his big mouth that could swallow them instead of worrying about the situation.
 * When Luffy's group went out to beat the kraken and lost their way back to the ship she mildly commented, that hopefully they wouldn't be ripped to shreds by some monster.

She speaks only if something noteworthy happens. When she does, she has been shown to possess an outstanding knowledge, especially in history. Her calmness is likely a result of the childhood that led to her life of hardship. The calamity that befell Ohara had a profound and traumatizing effect on Robin as a child, that she has only just begun to recover from.

She will not understand why people regard history as meaningless. To her, there is nothing worse than destroying objects of historical significance. She approaches life and the world at large in a calm manner. She studies the world for its history. She shows little interest in the Ancient Weapons that others such as Crocodile and Spandam seek. However, she might be the only one who is able to awaken them.

During battle, Robin tends to maintain a relaxed demeanor that only seems to change whenever the circumstances proved to be beyond her capacity to cope (i.e. a hopeless situation); more often than not, she would exhibit unshakable calmness and reserved behavior against an inferior adversary, to the point where she typically displays by using her powers to satisfy minor necessities (i.e. using a pair of arms sprouting from the ground to form a make-shift seat). And perhaps as a result of her violent past, she is very merciless during combat and like Zoro, she does not shy away from using deadly force. She will break the necks or spines of her enemies without hesitation, even when they cry for forgiveness. Despite her tendency to remain calm and collected, she can be quite intimidating and forceful when she wishes. This is exhibited when she essentially forces Brook to stop fooling around and continue his explanation. Robin: The things you have destroyed back there were priceless artifacts. Precious treasure whose importance cannot be measured... History may always be repeating itself, but humans cannot go back into the past... you wouldn't understand that, would you?

Yama: I... I understand... I won't... do it again... Forgive...

Robin: No.

She also has a strong sense of personal pride. She refused to participate in Franky's "Tactic No. 15" docking procedure during the battle against Oars. The reason was that she found it "embarrassing as a human being". She flatly added that they should never try it again.

Crew
Until after the Enies Lobby arc, Robin often tried to distance herself from other people, even her allies, as she knew that she was bound to leave them sooner or later. Upon first joining the Straw Hat crew she stated simply she had nowhere else to go, declaring that Luffy was responsible for her being alive and so he had to take responsibility for his own actions when she had decided to die. She rarely called her comrades by name, and instead referred to them using their ship-hand titles, such as Miss Navigator (Kōkaishi-san, i.e. Nami), Mr. Swordsman (Kenshi-san, i.e. Zoro), Mr. Long Nose (Nagahana-kun, i.e. Usopp), etc. She at first only called Luffy and Crocodile by their names, although in a professional manner as an agent. She does, on occasion, call Luffy "sencho-san" (meaning captain).

Over time, however, Robin becomes closer with her crewmates, and begins to get a sense of belonging with them, and has stated that she cares more about their well-being than that of the rest of the world. After seeing how far they will go in order to save her, she begins calling them by name in recent arcs, doing so with Luffy, Nami, Usopp, Chopper, Franky and Zoro so far. She is grateful to Luffy for taking her in, and is significantly more patient with his impulsive personality than many of her fellow crewmates, even laughing when he impulsively allows members to join, while the others are shocked (after all, it is through this she became a Straw Hat member). She is also far more tolerant of Luffy's behavior, which at times even makes her laugh. This is going back as far as when they were enemies in the Alabasta arc when he fought Crocodile as "Water Luffy", drinking an entire barrel of water and spraying it at Crocodile from his mouth to make him more solid. Luffy was the one person able to convince her that she should live even if the world doesn't want her to, and if so, they are his and his crewmates' enemies as well. In many ways, Luffy reminds Robin of the other D. carrier she befriended.

Robin is quite close to Nami, affectionately referring to her as "Nami-chan", and often spends time with her, particularly shopping when they have free time, and talking with each other. Robin sympathizes with Nami's frustrations at the male crew members' silly antics, but doesn't get upset by them. Sanji constantly flirts with Robin, as he does with Nami. He was the first member (excluding Luffy) to accept her as one of the crew. Sanji describes her as 'a distant, more mature beauty than Nami', yet calls her "Robin-chan" (vs. "Nami-san") which has a "cuter" and more childish aspect. He also tries to make her suffix cuter by changing it to "Robin-chwan" at times, but Robin, unlike Nami, tolerates his advances and typically responds with politeness. Zoro initially distrusted Robin, but he cares for her too as he is willing to fight for her when she is in danger, such as catching her when she was nearly killed by Enel. He was also the first one to jump to her aid when she was threatened by Aokiji. After Enies Lobby, Zoro completely trusts Robin and gets along well with her. Amongst the crew, Zoro and Robin are the most calm and serious in any situation. Robin gets along well with Franky, and she appreciates him risking his life to save her. She has a lot in common with him since both were wanted by the world government's Cypher Pol when they were children dispite of being innocent and they saw their adoptive family destroyed by the world government in front of them. Her relationship with Chopper exists on two levels. First on a somewhat maternal level, as she finds him "cute"; she acts quite motherly towards Chopper in contrast with Nami's more tougher grip, and second on an intellectual level, where she treats Chopper somewhat like an equal due to their mutual intellectual pursuits and love of books (despite the difference in disciplines). Usopp is the only one she addresses with -kun attached to a nickname, Nagahana-kun.

Friends
Professor Clover allowed Robin to become an archaeologist, it was his research on Poneglyphs that sparked her interest in the True History. Clover allowed her to read books in his library which sparked her interest in them. She was supported by the other archaeologists in the Tree of Knowledge. They were her only friends and they cared for her more than anything. Even when they threatened to ban her from the Tree of Knowledge if she continued to spy on the efforts to uncover the True History, they did so in order to prevent her from being branded as a criminal.

Aside from this, Jaguar D. Saul also held a special place in Robin's heart for befriending her during her periods of loneliness, recognizing her pain and encouraging her to laugh in hard times, in addition to sacrificing himself in order to save her life.

Revolutionary Army
The first members of the Revolutionary Army that Robin met (to her knowledge) were the ones liberating the slaves at Tequila Wolf. She was suprised to learn that she was referred to as the "Light of the Revolution" by them and that they had been searching for her for 10 years under the orders of none other than Dragon himself. They offered to take her to Dragon but she declined at first, saying that she had a crew. After she read Luffy's message in the newspaper, she decided to go with them to Dragon. She joked that she wished they would have come for her sooner (which they thought she was serious at first and apologized), but she said that she's glad with the way things turned out. She refused to come inside the ship, saying that she didn't want to go anywhere where she couldn't escape. The revolutionaries accommodated her by bringing blankets, drinks, food, a sofa, and a wind protector for her.

After the two year timeskip, she returned to Sabaody Archipelago alone but escaping some people. It's currently unknown what her relationship with Dragon or the other revolutionaries are now.

Enemies
During her time in Baroque Works, Robin was the enemy of those trying to save the kingdom from Crocodile's conspiracy, especially Nefertari Vivi, who believed that she had killed Igaram, and the Straw Hats. As a result, most of the Straw Hats were suspicious about her joining, until she won them over. Upon discovery that Robin joined the crew, Cobra worried of Vivi's reaction, however Vivi trusted that Luffy has some reason for having her in his crew, and seemed to not hold any grudge against Robin.

While investigating the ruins of Upper Yard, she was interrupted by Yama. His fighting style destroyed the land around him, and when she yelled at him to stop, he disregarded the importance of the ruins. Outraged, she defeated him and forced him to beg her for forgiveness. However even when he apologized, she denied him forgiveness and tossed his body, head first, upside down, to the ground, showing zero tolerance for anyone who disregarded history.

Robin's greatest threat is always from the World Government, since, from the age of eight, they have ruthlessly hunted her. Aside from the World Government, Robin has made many enemies in the past through her constant betrayal, the most dangerous of which is Crocodile. Wherever she went she was unable to find happiness and was constantly thrown out. And when the people she stayed with found out they were now the targets of the World Government, the group would turn on her, with the exception of Crocodile who agreed to protect her. To this end, Robin's claim is that her greatest enemy is the world itself.

Several other civilians hate her, fearing her ability to awaken Pluton. Iceburg is one such example, as he states that while he would prefer to burn Pluton's blueprints, he must guard them in case the World Government uses her to revive the weapon. However, his opinion of her changes after he realizes that she is willing to turn herself in to save her friends, finally admitting that she is a good person. Franky feels similarly about her at first, but after learning of her being forced to turn herself in to save her friends, he immediately sympathizes with her due to his sentimental nature.

While Robin fears the three Admirals for their reputation of being the most powerful fighters of the Marines, she fears Aokiji the most, for they had a personal encounter 20 years ago. Aokiji stated that he was not her friend, and he would hunt her down if she became a problem. However, he had let her live due to the wish of his good friend, Jaguar D. Saul, who also happened to be Robin's friend. After the war within Enies Lobby, Aokiji had seemed to form a somewhat benign relationship with Robin, stating "Ohara still lives".

Two of Robin's greatest enemies are former CP9 director, Spandine, and his son, Spandam, both of whom considered her a "devil". They activated the Buster Call in attempts to kill those dear to Robin (the citizens of Ohara and the Straw Hat Pirates, respectively). Robin herself, was the victim of their abuse of authority, suffering physical, verbal and emotional abuse from Spandam, until Franky freed her. Consequently, Robin took her revenge by seriously injuring Spandam when the opportunity arose.

Nico Olvia
Nico Olvia was Robin's mother and although the two went for many years without seeing each other, her mother still loved her deeply. She was proud of her daughter and considered her amazing for being able to read Poneglyphs at an extremely young age. Her only regret was she was unable to spend time with her daughter and all Robin ever wanted was to see her again and be with her.

Roji
Roji was Robin's aunt, via marriage to Olvia's brother. She disliked Robin and mistreated her from the very moment she walked into her house and treated her like nothing short of a slave. As the boat she boarded was hit and sunk, she is believed to be dead.

Other
Although they were related to her, Robin is never shown interacting with her uncle and cousin. Robin's uncle was seen defending her against his wife, but otherwise did little to help her or acknowledge her as a member of the family. Robin also had a father, however Robin never knew her father and his name remains unknown. All family members (except Robin's father who died many years beforehand) are believed to have died at Ohara. The children of Ohara usually picked on Robin, but are scared off by her Hana Hana no Mi powers, and their parents would call her a monster for it.
