Nico Robin/Personality and Relationships

Personality


Out of all the members of the Straw Hat Pirates, Robin is the most serene and has rarely been seen to act comically. She treats Luffy with more respect than the rest of the crew, even when he acts impulsively, to the point where she will laugh at his antics. Together with Zoro, she is one of the members that support Luffy's decisions unconditionally.

When the crew is sailing, Nico Robin is usually reading and investigating data from the places they visit. She is very wise and very patient in everything. Robin does not play a specific role in the ship, but she can foresee what can be found somewhere and that (in her own words), is of advantage to others. Luffy considers her a very intelligent member.

Through her heritage on the island of scholars, Robin is an archaeologist and historian who seeks the comfort and freedom to study the mysteries of the world. She is the quieter, more reserved crew member, rarely having outbursts 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). She even appears calm while speaking ominously around her crewmates. She has an "adult charm" about her, as stated by Sanji. Being described as the "mother" by Oda she in kind has shown maternal care for others like Chopper, Momonosuke, and Toko.

Morbid Behavior
Robin has a somewhat macabre side to her, and often points out gross or morbid facts, usually to the disgust of Nami or Usopp. Robin will usually be the first to speculate that a crewmate has met or will meet with a horrible fate, often going into grisly detail. In other instances, she will express enthusiasm for anything with a horror theme.

Examples include:
 * When Robin first joins the crew, Usopp asks her what her specialty is, to which she replies, "Assassination".
 * When Luffy, Zoro and Sanji were exploring a galleon that had fallen from Skypiea and were eaten by a giant sea turtle, Robin immediately states that they may have been eaten along with the ship.
 * When Nami asks if Zoro was eaten by the sky shark, she says that the clouds would be turning red if he was.
 * When Nami is forced to swing on a rope past the sky sharks, 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 Thriller Bark 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.
 * When they are attacked by the Cerberus on Thriller Bark, Robin says that she finds it "cute".
 * While the Straw Hats are looking for Nami, Chopper and Usopp at Thriller Bark, Robin says that they are not even able to hear their voices anymore, wondering if they were strangled.
 * While searching for a way to reach Fish-Man Island in the Shark Submerge III, 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.
 * While the other crew members commented on Sanji's bizarre luck in reaction to Duval's face, Robin quipped that he would certainly have an interesting death one day.
 * When Luffy's group went out to beat the kraken and lost their way back to the ship she mildly commented that hopefully they would not be ripped to shreds by some monster.
 * As Noah approached the battlefield between Straw Hat Pirates and New Fish-Man Pirates, she wondered whether the ocean would be dyed red if everyone was smashed by it.
 * When Robin heard the news that Nami, Franky, Sanji and Chopper were kidnapped by some mysterious men with rifles, she seemed concerned if they were already shot and had multiple holes in their body.
 * While riding on Brownbeard with Luffy, Zoro, Usopp and Brook, she commented that it would be nice if Nami and the others' arms and legs have not come off from frostbite.
 * When Usopp asked what had fallen, as the group was making its way up the left hind leg of Zunesha to get to the top, Robin said that it looked like a person that was bleeding with knives sticking out of him.
 * When Usopp saw Wanda wear Nami's clothes and asked for her whereabouts, Robin wondered if the Mink Tribe has a taste for human flesh.
 * When Wanda insinuated that the other Straw Hats and company had been slaughtered and their bodies were in a forest in Zou, Robin concluded that because their remains were intact it meant they were not used for sustenance.
 * When Jinbe destroys an enemy ship at Wano, Robin states they could be targeted by the ghost of babies who died at sea.
 * While she was posing as a member of the Beasts Pirates, Robin acted like she wanted to rip out Momonosuke's eyes.

Before the events of Enies Lobby, she often spoke only when spoken to or if something noteworthy happened. 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. However, as she begins to spend more time around the crew, her personality begins to ease up.

When Robin is rescued by the Straw Hats from Enies Lobby, it is then that she considers herself both their friend and an official member of the crew. After the timeskip, Robin's personality is much more relaxed and playful in nature (as evidenced by her common giggling), quite possibly due to her exposure to the other Straw Hats. She has also been shown to possess an outstanding amount of knowledge, especially in history.

Running Gag
In spite of her mature appearance and calm demeanor, she seems to have a child-like imagination. Although she is often shown imagining bizarre, silly, or cute images, she will rarely give voice to these thoughts, maintaining the straightest of "poker faces". When Bartholomew Kuma mentioned that he was the user of the Nikyu Nikyu no Mi, Usopp thought that the calm sound that the fruit's name gave when being said meant that there was a "soothing" type for Devil Fruits, which made Robin imagine three cute cats showing their paws and meowing, while still having a serious expression on her face. Another example of this is when she, Luffy, Zoro, and Usopp were going to cross a river to get to the Ice Region of Punk Hazard. Zoro gave the idea of swimming across since being on the Fire Region of said island got them sweaty. Luffy agreed to the idea, thinking that Zoro and Usopp would carry him and Robin across since they cannot swim. This made Robin imagine Zoro and Usopp swimming happily while carrying Luffy and her, while also being happy and smiling, and still showing her normal smiling face on the outside, even though Usopp said that there was no way they would swim across while carrying them. She also imagined Dressrosa as a dress-wearing old woman when Luffy mispronounced the name.

Her silence seems to stem from her sense of decorum and personal pride on many occasions, she flatly refuses to engage in any behavior that would be considered embarrassing. 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 even made a supposed embarrassed face, though it was more noticeable). She then rather flatly added that they should never try it again.

Maturity


One of Robin's defining traits is her utter lack of fear regarding a situation as she usually maintains a positive and even cheerful demeanor. She has only shown fear in very few cases and always involving an extremely dangerous threat directly falling on her, like during the Buster Call at Enies Lobby, when the Warlords Crocodile and Kuma tried to kill her (Kuma in reality just attempting to save her), and when the Admirals Aokiji and Kizaru appeared in front of her.

Also, unlike Nami, Robin rarely gets angry with any of the crew's antics or when they do something that puts them in danger and instead giggles at their antics. This was shown when Luffy told the crew he challenged Big Mom, one of the Four Emperors, which left the whole crew horrified of Luffy threatening an Emperor. To this, Robin just smiled and laughed. An example of her voicing displeasure with one of her crewmates can be seen while the group is hiding out on Punk Hazard in which she reprimands Franky twice after he speaks and makes lewd faces while trapped in Chopper's body. However, upon Trafalgar Law returning him and Chopper to their original bodies, Robin cheerfully expresses her joy in having the two switched back.

In contrast to her distant and reserved demeanor, Robin is actually caring and compassionate. This is shown when she saved Luffy, twice, from Crocodile's quicksand and gave him the antidote for the poison despite initially being enemies. Even so, after bringing Luffy back up, she left him in the care of Pell and told him that Luffy was responsible for returning Vivi to her country. During her childhood, Robin was bullied and an outcast by the residents of Ohara because of her Devil Fruit, though she bared no ill-will towards them. She did mess with the kids who picked on her, in a mischievous way. The experience she had the destruction of her home, as well as being betrayed by the people who saw her as a demon and attempting to turn her over for money left Robin to have a jaded view on people. While so, this made Robin become deceptive as well, using others to escape her past, including Baroque Works and even Crocodile. It was after spending her time with the Straw Hats when she took Saul's words at heart that she started to regain her kind nature. It can be said that Robin would never harm someone who has not done anything to her, as she did save Luffy before they became crewmates. She can be very loyal and selfless, as she was willing to give herself up to protect her crew. Because of her tragic past of the Buster Call, Robin would warn people about the incoming ships even to her enemies. After Spandam accidentally invokes the Buster Call, while lamenting the Marines' incompetence over the radio, Robin went out her way to warn everyone on Enies Lobby, including the Marines and Cipher Pol agents, to evacuate. When Kyros was fighting Diamante, Robin vowed to protect Rebecca so Kyros could focus on fighting him. Also, she tried to protect an injured Law with her own body from an attack from Doflamingo. She even helps the residents of Zou to treat Zunesha's wounds.

Love For History
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 will never understand why people regard history as meaningless. To her, there is nothing worse than destroying objects of historical significance. She became furious at Yama because he destroyed valuable Shandorian artifacts, and swiftly defeated him after. 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).

As a result of her violent past, she is very merciless in combat and 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, as demonstrated when she fought Yama near the ruins of Shandora. 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. She even states her willingness to be a demon if she has to be, especially for the people counting on her.

Despite Robin's ability to cope with the bizarre, she was unable to take in the idea of Dwarves and was even shocked by their nature of easily trusting people, something she usually laughs off whenever Luffy does it. Robin was originally the only member of the crew to possess no face-faults. However, after arriving at Dressrosa, her significant change in personality begins to present itself. Robin has since expressed multiple facefaults demonstrating that she is no longer the stoic, uncompromising individual she used to be. Robin was also overcome with emotion at the sight of Kanjuro's Nobori Ryu technique, which produced a pitiful-looking dragon that she found to be overwhelmingly cute to the point of blushing, whom the crew soon dubbed "Ryunosuke". She was driven to tears at its noble effort to climb Zou's hind leg to the top, struggling because of its feeble features, and then honored its memory when it turned back into a drawing and ceased to be "alive" by placing flowers on its "grave" where it had reverted to drawing form.

Crew
For the past twenty years, I've been able to run away and survive no matter what the circumstance. That's only because I had nothing to protect. Because I was willing to betray others and use them as a shield. But not now. For the first time in all these years I can't do that. They picked up the life I gave up on, returned the heart I lost, and continued the dreams that I no longer believed in. Even after all I've done, I've found friends who will still believe in me. Before 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. Since her first bounty, Robin had constantly been betrayed by people she came to trust; they all turned on her for the sake of money. As a result, Robin took a jaded view on people and never really trusted anyone. Even before she joined, Robin was very intrigued of the activity and potential of the Straw Hat crew (possibly because their captain was one of the few people in the world with the middle initial D, just like the giant who saved her). Even while they were enemies, Robin never acted hostile or aggressive towards any of the crew. She even became withholding to her Baroque Works allies, never informing them of the identity of Sanji whom she identified at Whiskey Peak; which resulted to their escape at the Casino and saving Luffy from being buried in the desert after he was beaten by Crocodile at Rainbase.

Upon first joining the Straw Hat Crew, she simply stated she had nowhere else to go, declaring that Luffy was responsible for her being alive when she had wished to die and therefore had to take responsibility for his own actions. 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 develop 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 now calls them all by their names. During the assault on Enies Lobby, she realized she has finally found the friends that Saul said she would. She has also stated that, aside from saving her life, they were responsible for reviving her dream. After the timeskip, Robin feels confident about her place in the crew. When Nekomamushi said he was worried that people who wanted to read the Poneglyphs would come after her, Robin stated she had strong friends who would protect her.

Monkey D. Luffy
Our captain is worth the risk... of our lives! In every situation... Luffy is the trump card that leads us to victory!! She is grateful to Luffy for accepting her into his crew 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). And as Robin sailed and ventured with the crew longer, she started to become closer to and care for Luffy as well as the rest of the Straw Hat crew. She is also far more tolerant of Luffy's behavior, which at times even makes her laugh. This goes as far back as when they were enemies in the Arabasta Arc, when Luffy fought Crocodile as "Water Luffy", drinking an entire barrel of water and spraying it at Crocodile from his mouth to make him more solid. She seemed to have taken a liking to Luffy from their initial meeting aboard the Going Merry, where his bold personality intrigued her enough to want to meet him again. Luffy was the one person who was able to convince her that she should live even if the world does not want her to, and even if that were the case, the world is his and his crewmates' enemies as well. In many ways, Luffy reminds Robin of the other D. carrier she befriended. This could have also contributed to her initial interest in him, as she was aware of his full name at their first meeting and inquired about it further when she rescued him after his first fight with Crocodile.

After she officially became a part of the crew, Robin was surprised by Luffy's connections to certain people such as Shanks, Monkey D. Garp, and Monkey D. Dragon. She remarked that he truly had an interesting story and was amused by it.



Robin also seems to be very devoted to Luffy, as he is the only person whom she wants to get stronger for. This shows how great her dedication to her captain has become after the Enies Lobby Arc. Upon learning of Ace's death, Robin was very shocked and became greatly concerned about Luffy's wellbeing. Like Zoro, she follows Luffy's decisions whatever the consequences, such as when he decided to form an alliance with Law to take on Emperor Kaidou. Another reason for her great loyalty to Luffy is that he is the very person who helped Robin find her will to live. Interestingly enough, Robin has started a habit of referring to people by the names Luffy calls them by, even though she clearly knows their true names.

After the timeskip, Robin was amazed by Luffy's strength after seeing him defeat the Kraken and watching him use Haoshoku Haki. During the Dressrosa Arc, she impeded toy soldiers from chasing Luffy, as he was going to face Doflamingo. When she confronted Gladius, she really expressed her devotion to Luffy, saying that he was worth dying for because he is always the trump card that brought victory. Even though Nekomamushi warned her that many strong people would try to kidnap her in order to read the Poneglyphs, Robin seemed unconcerned and feels confident enough in her captain's capabilities.

Roronoa Zoro


Robin and Zoro have a unique relationship and also arguably the most in common out of all the Straw Hats. Zoro was the one who held out the longest on trusting Robin, and bluntly told her he did not when they were made to team up during the South Bird Hunt. On the other hand, while she used various tricks to gain the trust of the other Straw Hats (save for Sanji, who immediately trusted her because she was a beautiful woman), she never tried to trick him into accepting her. She also treated him differently than she did the other Straw Hats, treating him as her equal and even feeling comfortable enough to divulge a bit of info about her mysterious past to him.

After the Arabasta Arc, when Robin had joined the crew, in spite of him initially being wary of her, Zoro later on demonstrates that 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 assaulted by Enel and furiously attacking him for harming her, and being the first one to block Aokiji's attack when he threatened her. Furthermore, not only did he fight to save her from Enies Lobby like the rest of her friends, but he was also the one who won the correct key that unlocked her Seastone handcuffs. He also runs to her aid alongside Sanji when she’s harassed by an invisible Absalom.

Robin herself is willing to protect him from any kind of danger he is in, such as catching him with her Spider Net after he was kicked extremely high into the air by Oars, desperately trying to save him from getting killed by Kizaru and stopping him from being killed by the water pressure when he wanted to exit the ship on the way towards Fish-Man Island. In fact, she appears to care a great deal about his well-being as shown in the Thriller Bark Arc. She had wanted to know so badly about what happened between Zoro and Kuma that she uses her powers to eavesdrop on Sanji's conversation with the Risky Brothers on the very matter, and like Sanji decides to keep the truth a secret from Luffy. During the party, Robin is one of the Straw Hats (the others being Nami and Chopper) who watches over Zoro, commenting to him how nostalgic Bink's Sake was to her.

After Enies Lobby, Zoro and Robin fully trust each other and have grown closer. Due to also having similar personalities, they can often agree on certain matters. They have only had two disagreements so far, during the search for the South Bird and two years later during the voyage to Fish-Man Island, but that was only done out of concern.

Following the timeskip, the two are shown to still get along quite well and are frequently seen together. While demanding Fukaboshi to bring the rest of the crew safely back to the palace during hostage negotiations, she is the first one Zoro mentions. In Punk Hazard, she shows concern for him getting cold when he opts to take his jacket off. Robin is seen being very impressed by Zoro's improved strength and skills on more than one occasion. She appears to really believe in him in general, as she was surprised that the swordsman was not able to make short work of Pica in the Dressrosa Arc. When Viola tells her about Zoro's plan to stop Doflamingo's Birdcage over the Den Den Mushi, Robin is not surprised he would come up with such an idea, commenting “how very like him”. In the Zou Arc, Robin shows she really values Zoro's opinion when she asks him if they should wait for Kin'emon and Kanjuro to catch up to them and she follows his decision when he decides they should go on ahead without the two samurai. This indicates that Robin sees Zoro as the leader when Luffy is not around.

Nami


Robin is quite close to Nami and often spends time with her, particularly going shopping when they have free time, and talking with each other.

When she first joined the crew, Nami initially distrusted her, but she was swayed by a bag of jewels that Robin stole from Crocodile. She sympathizes with Nami's frustrations at the male crew members' silly antics but does not get upset at them. Nami was one of the Straw Hat members most upset at Robin's capture at the hands of CP9 and worked tirelessly to get Robin back and embraced her tearfully with Chopper when they did.

Soon after Robin joined the crew, Nami began to view Robin much like a big sister and yet both of them have motherly instincts towards Chopper and Momonosuke.

Usopp


Usopp was naturally suspicious of Robin at first, due to her working for Baroque Works. When he asked what Robin specialized in and she replied "assassinations", Usopp was terrified and told Luffy that she was too dangerous. However, when he saw the fun aspect of Robin's Devil Fruit, he forgot his fear of her, and they got along well with each other.

Robin does not typically respond to Usopp's acts of cowardice and more often than not will play it off like it never happened. In spite of this, Usopp cares about Robin's well-being and was in fact, the one who prevented her from being taken from Enies Lobby to Marineford under the guise of Sogeking and he was able to convince Robin to have faith in others and herself. It was after this incredible rescue that Robin ceased referring to him as "Nose-kun" and simply, "Usopp".

After the timeskip, they are shown to get along much better and Usopp is no longer unnerved by her making morbid remarks over the fate of missing crewmates. They work together in a more efficient manner. Many examples of this are seen during the Punk Hazard Arc, where Usopp unhesitatingly carried her and Luffy after they were immobilized by the sea. During the Dressrosa Arc, Robin put her faith in Usopp to save her from being a toy and was happy to see him come through and save her.

Sanji


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 more childish aspect, despite the fact that she is older than him. He also refers to her as "Robin-chwan" at times, but Robin, unlike Nami, tolerates his advances and typically responds with politeness. When she was first taken into the crew, Robin did not even try to earn Sanji's trust, due to his obvious weakness for women. Sanji treats Robin slightly differently from Nami, knowing she is able to look after herself, but he does worry about her in battle and will still jump to her rescue when she is in danger (like when Gecko Moria stole her shadow). Even after Robin allegedly betrayed the crew, Sanji is the first to forgive Robin, even before learning why Robin did what she did, and pursued her without hesitation. Sanji did not forgive Wanze or Jabra for speaking ill of Robin and violently beat them both up for it.

In Zou, Robin, like the rest of the crew, was concerned over Sanji's predicament with Big Mom. She also displayed knowledge of the Vinsmoke Family, but had no idea that Sanji was related to them.

During the Raid on Onigashima, Robin answered Sanji's plea for help when he was captured by Black Maria, afterwards thanking him for relying on her. During her fight with Black Maria when the Tobiroppo member started insulting Sanji as a laughingstock for calling for her help, Robin simply said that Sanji is a kind-hearted person and him relying on her means so much to her, even saying he is worthy enough to be called one of the "wings" of the Pirate King.

Tony Tony Chopper


Her relationship with Chopper exists on two levels. First, on a somewhat maternal level, as she finds him a "cute little furball", as she acts quite motherly towards Chopper—in contrast with Nami's tougher grip. Secondly, on an intellectual level, where she treats Chopper somewhat like an equal due to their mutual intellectual pursuits and love of books. Her fondness for Chopper appears to have increased after the timeskip, as after the battle in the Fish-Man Island Arc, when Chopper exhausts himself greatly from using his Monster Point, Robin happily rests him on her lap as he begins to fall. Robin will also use her Devil Fruit power to play with him, such as tickling him or making him roll over. This affectionate treatment is not missed by Chopper as seen in the Davy Back Fight when Porche was getting too grabby with Chopper so the doctor ran to Robin, and she kept him from the female pirate. Also, it is shown in the Punk Hazard Arc, when Law put Franky into Chopper's body, she was shown to be greatly displeased as Franky made very lewd faces and spoke while in Chopper's body, which she told him never to do either action ever.

Franky


Robin gets along well with Franky. They have a unique bond, because he is the first character outside of the Straw Hats who was willing to fight for her life (during Enies Lobby). Since then, Robin and Franky have been a compatible duo in numerous occasions and battles, such as on Enies Lobby, Thriller Bark, and Punk Hazard, as well as in non-canon moments in movies and specials. One example is their working together to bring down and seriously injure Spandam as both of them saw him as a mutual enemy due to the torture he previously subjected them to.

She has a lot in common with him since both were wanted by the World Government's Cipher Pol when they were children despite being innocent and they both saw their loved ones destroyed by the World Government in front of them. The two of them have shared a heartwarming philosophical connection over the evil (or lack of evil) present in a dangerous item or person existing. Franky's staunch devotion to the words of his master, that simply existing is not a crime, and no matter what, someone (or something) must be proud of its existence, moved Robin as she considered the morality of her own existence while being capable of awakening the Ancient Weapons. Franky is the one who could relate to her the most for the fact that she was hunted because she exists, he was also chased by government. Even if Franky got to know the real Robin only shortly in Enies Lobby, he says that he did not expect her to be this kind and he cannot really trust everything they say about her. He also tells Robin to cheer up since she has friends out there who are willing to risk their lives to save her. He demonstrates the fact that even if Robin indeed holds the most dangerous ability in the world, as long as she does not fall into the hands of the government and she is not willing to use her power to destroy the world, she is not dangerous by burning the blueprints and betting on the Straw Hats that they will save Robin. Franky got the chance to escape from being targeted by the government again if he hands Robin over, but Franky refuses the offer. After being questioned why he is saving someone like this when he is not even a pirate, Franky responds that he is not only moved by the Straw Hats fight for Robin, but it has subsequently given him the chance to take his long overdue revenge against Spandam.

When the crew tries to persuade Franky to join them, Robin offers to lend them a hand (literally). When Franky is crying too much, Luffy tells Robin to stop, but they are shocked to see that Robin is not doing anything anymore and she is smiling instead. Robin then says that Franky is truly a clever guy, blaming the pain on her. Franky called her "our beautiful historian" during their first meeting after two years. There is an ongoing gag that Nami and Robin are completely numb to the "romance" of Franky's robotic creations and body (while Luffy, Chopper, and Usopp are left in awe). Ironically, they were also the only crewmembers that were initially enemies of the Straw Hats. They were both eventually won over by the crew's antics and seeing how far they're willing to go to protect their own. Despite all of this, Franky also holds the distinction of being one of two crew members capable of annoying her (to the point where she expresses it openly) along with Brook. While she is amused by the rest of the crew's antics and occasionally participates, she outright rejected participating in "docking" mode in Thriller Bark saying it was too embarrassing. Furthermore, when the crew's hearts were scrambled in the Punk Hazard arc, she expressed her disgust at Franky's facial expressions and speech while in Chopper's body. After they were switched back, she voiced her relief most fervently, saying she hopes it never happens again. Franky on the other hand has shown occasional dislike towards the morbid remarks that Robin often makes towards missing crewmates, such as when the rest of the crew were searching for Nami, Usopp, and Chopper on Thriller Bark. Despite all that, Robin seems to have a close relationship with Franky, since she does not mind him sleeping on her lap. In Onigashima, Franky invited Robin to ride with him on the Kurosai FR-U IV, which she happily accepted before Brook took her seat.

Brook
She stood emotionless when she first met him and, similarly to how she responds to Sanji's advances, she does nothing when Brook asks to see her panties. Robin did find him annoying when Brook was cracking jokes instead of telling them how to stop zombies and had difficulty stopping Franky from hurting him. Nonetheless, she developed respect for him after hearing his wish to reunite with Laboon and was grateful to him for saving her and Franky from zombies. Robin was amused by Brook's easy entry in the crew, since it was just like her own entry. They are on comfortable, friendly terms with each other. She also seems to hold Brook to high standards as the oldest member of the crew beside her and Franky and finds it slightly annoying when he does not act his age. With that said, however, she is still very fond of Brook, especially his music.

After the timeskip, they still get along with each other and on Punk Hazard, Brook saved Robin and her group from freezing in the river by Brownbeard and his crew. During the raid on Onigashima, Robin paired up with Brook as they went to save Sanji from Black Maria. During which, they proved to be an effective team, working flawless with one another well displaying a great deal of trust and confidence in each other's abilities. Brook trusted Robin enough to let her fight Black Maria, one of the Tobiroppo, by herself.

Robin and Brook share a bond as members who lost everyone they loved and spent decades alone until they joined the Straw Hat Pirates.

Jinbe
Robin was concerned about Jinbe when he and Luffy were violently arguing over how to stop the New Fish-man Pirates' rebellion. She interferes during their confrontation, insisting that they should not fight. She consents to Jinbe's request to liberate the human pirates enslaved by the New Fish-man Pirates but does question if they will hold a grudge against fish-men in general for their mistreatment. Robin muses he must really want to join their crew after Jinbe requests to be given time to conclude his affairs before becoming their crewmate.

At Wano, she was more than pleased to see him again and was happy when he became the official helmsman. In Onigashima, Robin decided to walk with Jinbe, saying his maturity was a relief.

Clover
Professor Clover allowed Robin to become an archaeologist after she passed her test; 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.

Jaguar D. Saul


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. Saul was shipwrecked in a storm, and then sent adrift in the ocean until fatefully landing on Ohara itself. There, he met and, at first unknowingly, befriended Nico Robin and was reunited with Nico Olvia. After promising Olvia that he would ensure Robin's safety, Saul was confronted by Vice Admiral Kuzan (Aokiji) as he was destroying the Buster Call ships. As he was being frozen, Saul smiled and laughed, cryptically echoing the way Gol D. Roger was executed two years prior.

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 surprised 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 about the way things turned out. She refused to go inside the ship, saying that she did not want to go anywhere where she could not 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 is as of right now. It is also revealed that during the timeskip, Robin had gotten to know Koala, Sabo, and Hack, introducing them to her fellow crewmate Usopp. Robin shows she is aware that Sabo is Luffy’s brother and heard his story of how they were separated. She also agreed to watch over Luffy after Sabo asked the crew.

During the Zou Arc, Dragon asks Koala about Robin as he and the other Revolutionaries were worried due to rumors that Robin had been captured on Sabaody Archipelago and was relieved to hear the rumors where false, showing that Dragon at least cares about Robin's well-being.

Toko
The two first met at Sanji's soba noodle stand and Robin immediately took a liking to the young kamuro, even laughing at her joke. The next time they crossed paths was during Orochi's banquet. When Toko becomes targeted by the Shogun after laughing at him, Robin dropped her mission to protect her. Later on, in Rasetsu Town, Robin was greatly alarmed when she saw the girl appearing at the execution site and putting herself in harm's way. Following the escape to Amigasa Village, Robin is mostly seen at her side, holding her as she sleeps and also being with her when she visited her father's grave.

Nefertari Vivi
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 Hat Crew were suspicious about her joining, until she won them over. Upon discovering that Robin joined the crew, Cobra was 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.

Iceburg
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.

Kuzan


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 allowed her to 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 have formed a somewhat benign relationship with Robin, stating "Ohara still lives".

Yama
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. Robin, infuriated by his disregard of history, drew him away from the ruins, taking a few hits in the process. Once in open terrain, she proceeded to go all out, employing rather painful methods such as slamming Yama into a tree and flipping his Ten-Fold Axe to hit him. After this beating, Yama begged and apologized to Robin, saying that he now understood the value of history. Robin ignored his plea, stating that what he did was still inexcusable. Then, when Yama tried to grab Robin, she broke his fingers with her extra arms and used Cien Fleur: Delphinium to hurl the commander off a cliff and down to a lower level of Upper Yard, then held him in a lock position increasing the potential impact, while using "Seis Fleur: Clutch" to snap him before he crashes into the ground. After Enel was deposed, it is unknown what happened to Yama.

World Government
Robin's greatest threat is always from the World Government, since, from the age of eight, they have ruthlessly hunted her. Wherever she went she was unable to find happiness and was constantly thrown out. Also, 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.

The persistence of the World Government and their view on her being a threat would not cease even after two years had passed, as during the Raid on Onigashima, the World Government sent numerous ships out to Wano, intending to place Wano under the control of the World Government, but secretly having a second order for its agents arriving there with the capture of Robin, still seeing her as a threat. This order was later seen being put into action, when some CP0 agents chased Robin and Brook in the castle, with Robin wondering why the CP0 was in Wano and her being unaware of her being still a thorn in the eye of the Government.

Crocodile
Aside from the World Government, Robin has made many enemies in the past through her constant betrayal, the most dangerous of which is Crocodile. Crocodile's connection to Robin was a strictly business-related one; he did not consider her a friend, but only as a tool for his own ambitions. Although sheltering her from the authorities in exchange for her services, he never once showed her compassion; she was just expected to follow orders. He held no pity for her when she failed to deliver Pluton and did not think twice about striking her, although he did admit she had been a beneficial partner to him moments beforehand.

Spandam and Spandine
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, though the latter was triggered accidentally). 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 (namely, Seis Fleur Slapping him silly and, in the end, breaking his spine).

Black Maria
Robin first confronted Black Maria when Sanji called her for help and proceeded to fight with Black Maria eventually leading to Robin being the victor.

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.

After the truth was spoken to the World Government by Clover, Olvia was confronted by Robin as she was being taken away and finally, after Robin's pleas, she admitted her relationship with her. As the Buster Call was about to begin, Spandine ordered that she be taken with them, but panicked after being almost directly hit by an explosion and ran off. Nico Olvia was left behind and was finally reunited with her daughter. She hugged her and remarked that she was very proud of her. She then pleaded to Saul to take Robin to safety and told Robin to continue to live, to hand down the history to others, and to live her life to the fullest.

Roji
After her husband died, Olvia set out on a six-year journey to research the Poneglyph along with thirty-three other archaeologists. Although she found it regrettable that she had to leave Robin, it was something she felt she had to do: she left Robin in her brother, in his wife's, Roji's care. 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.

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, she never knew him, 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 the children as well as their parents would call her a monster for it.
