Ruby is a former student of Signal Academy. While there, she was taught how to wield Crescent Rose by her uncle and teacher, Qrow Branwen, and made several friends with whom she tried to keep in touch with during Volume 1.
Ruby is a former first-year student at Beacon Academy. She was admitted two years earlier than the average student, as Professor Ozpin was impressed by the fighting abilities she exhibits during her battle with Roman Torchwick and his henchmen, as well as her silver eyes.
Ruby is the leader of Team RWBY. Despite being the youngest member, her team respected and followed her leadership faithfully, albeit after some hesitation on Weiss Schnee's part. She shares a close personal bond with her teammates, and is visibly disheartened upon hearing of the team's disbandment during "End of the Beginning". After Ruby reunites with Yang Xiao Long and Weiss in "Known by its Song" and Blake in "Haven's Fate", the team is reformed.
Ruby is on good terms with all members of Team JNPR, and she often interacts with Jaune Arc. In "End of the Beginning", following Beacon Academy's destruction and Pyrrha Nikos' demise, she sets out with the remains of Team JNPR to Haven, in Mistral, in hopes of uprooting the conspiracy that left Beacon in ruins. Several months after leaving Patch, Ruby is shown to have grown closer to them and they all consider themselves a team that will stay together. However, in "Kuroyuri", Ruby expresses her guilt to Jaune about dragging all of them along and placing them in grave danger.
Ruby is on good terms with all members of Team CFVY. She and her team bonded with their peers early into the first year, and respects the team's skill. The two teams lost touch after the Fall of Beacon.
Qrow is Ruby's uncle and a former teacher at Signal Academy. He saved her and Yang from Beowolves when they were young children, and he taught Ruby how to wield Crescent Rose among various other things. Ruby mentions to Professor Ozpin that she was "complete garbage" before Qrow started training her. Weiss suggests in "It's Brawl in the Family" that Ruby got her recklessness from Qrow.
At first, Ruby is shown to adore her uncle in "It's Brawl in the Family", as she greets him with childish glee and claims to Weiss that Qrow was winning in his battle with Winter Schnee.
In "End of the Beginning", Ruby learns from Qrow about the heritage of her silver eyes. With Ozpin missing, her uncle vows to finish his work, and Ruby volunteers to assist him. Qrow accepts, but he tells her to recover first while dropping a hint about answers being in Haven.
Qrow follows Ruby when she sets out on her mission to Haven with the remaining members of Team JNPR. In "Tipping Point", Qrow appears at the last second to stop Tyrian's stinger from striking Ruby, giving her a reassuring smile. As Qrow and Tyrian fight in "Punished", Ruby tries to help him, but he tells her to stay back. However, she does not completely obey. After the battle, Ruby shows concern for her uncle when he collapses from his injury.
In "A Much Needed Talk", after Qrow fills her and the others in on what is going on with Salem, Ruby confronts him about her absolute trust in him not being reciprocated when he followed Team RNJR instead of joining them. Qrow reveals that it was not about a lack of trust on his part, but that he was protecting them by keeping back due to his misfortune Semblance. This temporary clash does not damage their relationship, and Ruby is very distressed to later discover that Qrow is suffering from being poisoned by Tyrian. She carries him on a stretcher to get help and sticks with him when Team RNJR needs to split directions.
Despite her obvious admiration of him, however, she is annoyed when he comes home drunk, which is shown in "Welcome to Haven".
In "Argus Limited", Ruby stops Qrow from arguing with Dudley, and he immediately complies. In "Uncovered", Ruby is encouraged by Qrow to do what she believes is right, prompting her to ask Jinn about Ozpin's secret. In "The Coming Storm", Ruby expresses her concern to Weiss that Qrow will drink all of the alcohol they have found to cope with his depression after his falling out with Ozpin. In "Alone in the Woods", she is angered with her uncle for oversleeping when he is supposed to be the watchman. Ruby tries comfort Qrow during his depression, but she is merely brushed off. Later, while escaping from the Apathy, Ruby has to drag a severely intoxicated Qrow, who is oblivious to the danger pursuing them.
In "Dead End", after a fail attempted to get in to Atlas, Ruby tries to reason with Qrow about another way to get to Atlas, but he ignores her. She gets frustrated when Qrow does not respond to her call. In "Lost", Ruby has had enough of Qrow's recent actions after finding passed out on the stairway of the Cotta-Arc house. She later stops him from getting away from the group and counters his refusal of Jaune's plan of stealing an Atlas airship.
In "Stealing from the Elderly", Ruby shows concern for Qrow as he worries about their plan. When her uncle later starts freaking out after the plan goes wrong, she confronts him and states that they are not his responsibilities, but that they need him as a Huntsman now. In "Seeing Red", when Qrow tries to stop her from confronting Caroline Cordovin, Ruby gives him a stern glare and tells him that she needs him to trust her. She defeats the Colossus and is caught by Qrow, saying, "Told ya" with a smirk.
According to interactions between Ruby and Yang, Ruby does not seem to like it when Yang tries to lecture her, stating that she sounds like their dad. Also, during her interaction with Penny regarding overprotective fathers, she says that she knows how it feels with a sympathetic face, signifying his high degree of over-protectiveness, which she does not seem to really enjoy. However, Ruby also quotes her father and mother as the ones who taught her to help others.
In "Field Trip" Ruby is overjoyed that their father has sent Yang and her a package.
In "End of the Beginning", Ruby is watched over by Taiyang as she recovers. She later leaves home in the winter without telling her dad personally, leaving only a letter explaining her departure.
Summer is Ruby's late mother. According to Yang, Ruby was left torn following her mother's death but was probably too young to understand it at the time. Ruby apparently visits Summer's Gravestone routinely, doing so in the "Red" Trailer, "Round One" and "End of the Beginning". Ruby is seen talking to Summer about the events in her life, casually addressing her as if she were still there. Ruby also remarks that she still misses her.
In "Our Way", during Ruby's flashback, she has a memory of Summer.
Ruby is seen to clearly love her pet dog, as evidenced by her jumping for joy when he arrives in her team's dorm room. Ruby even goes as far to sneak Zwei on her mission with her team as they shadow Huntsman Bartholomew Oobleck.
Prior to meeting Raven, Ruby has been wary of her, shown when Qrow airs his suspicions of Raven having the Spring Maiden in her tribe. When they finally meet in "The More the Merrier", Ruby tries to reason with Raven, saying that fighting Salem is not hopeless and asks the bandit to join them to fight together. Her efforts are in vain, however, as Raven allows Cinder to attack Ruby.
Being Beacon Academy's headmaster, Ozpin invited Ruby to attend his school after their first encounter shortly after the events of the Dust store robbery. As with Glynda Goodwitch, he is impressed with Ruby's skill, stating that he had "only seen one other Scythe wielder of that skill..." He is later seen paying particular attention to Ruby's performance during the initiation. Ozpin is also very interested in Ruby's silver eyes. Ruby entrusts Ozpin when she discreetly tells him of the White Fang hideout at Mountain Glenn in "Field Trip". He is also seen giving her advice in "The Badge and The Burden, Pt.2" and "Dance Dance Infiltration".
In "Round One", Ruby stated that the more she gets to know him, the more he starts sounding like her uncle, Qrow.
When Ruby reunites with Ozpin in "Unforeseen Complications", she tries to assure him that all of the hardships she and Team RNJR went through were not his fault, but to no avail.
Ozpin personally trains Ruby in hand-to-hand combat through Oscar Pine. Whilst Ruby is able to best Oscar, Ozpin himself is more of a challenge and he defeats her while explaining faults to her approach afterwards.
In "True Colors", Ruby asks Ozpin if Salem has the Relic of Choice stored at Beacon now that Cinder is the Fall Maiden. Ozpin reassures Ruby that the Relic of Choice is "a bit harder to find" than those at other academies. Ozpin also anticipates her question of whether his cane is a Relic or not, and Ruby, Ozpin and Qrow share a laugh when he answers.
In "Uncovered", Ruby's faith in Ozpin begins to waver as she sees his mistrust in humanity. She later goes against his pleas and asks Jinn about his secret, prompting him to charge at her to no avail. In "So That's How It Is", though visibly upset with Ozpin's deceptions, Ruby asks him what his plan is to defeat Salem, hoping he will somehow redeem himself. Though her inquiry proves to be in vain, as Ozpin admits that he has none.
In "Dead End", it reveals that Ruby is not sure if she should trust Ozpin again.
Glynda rescued Ruby from Roman's attack in her first appearance. After a short battle, Ruby, excited about her being a Huntress, asks her for her autograph, but she instead lectures her about putting herself and others in danger.
However, she is shown to be slightly impressed by Ruby's skill and bravery, going as far as to want to send her home with a "pat on the back". However, this display of affection is short-lived as immediately after, Glynda continues with, "and a slap on the wrist", hitting the desk in front of Ruby with her riding crop for emphasis.
Weiss Schnee is a fellow schoolmate of Ruby's. Their first acquaintance was on bad terms, with Ruby knocking over Weiss' luggage, leading her to berate Ruby about the importance of the contents of the luggage, further accusing her of being "brain dead" due to her nervous expression after the mention of Dust. Ruby was seriously upset by Weiss' aggressive behavior and by the fact she has made what she has termed "a negative friend".
Weiss has since stated that Ruby's hyperactivity and lack of forethought is a big cause of tension between them. The two have learned to work together and there is some indication that the tension is lessening, now that they are both parts of Team RWBY. By "Players and Pieces", both are able to open to one another slightly but have not become friends yet. Although Ruby appears to try befriending her, Weiss is still annoyed by Ruby's childish antics, as seen in Peter Port's class lesson about the Grimm.
But after Ruby talks with Ozpin and Weiss talks with Port, the two seem to be on better terms with each other, with Weiss saying she believes Ruby can be a great leader and promising to be the best teammate. Although they have reconciled, Weiss is still stern with Ruby when she makes mistakes, such as calling her a "dunce" after she misunderstands Pyrrha Nikos' Semblance of "polarity" as being the power to "control poles", when it actually means controlling magnetism.
By "The Stray", Ruby and Weiss have developed some rapport, and they are seen acting far more friendly to each other. However, after Blake's accidental revelation of being a Faunus and former member of the White Fang, Ruby stills seems to be distressed by Weiss' attitude, as much of which also causes her pain, in sense of being a leader and keeping her friends together.
As of "Welcome to Beacon", the two seem to have developed a better and closer relationship, which was seen when after the two lost against Yang, each on different turns, the two hug and "cry" together. Ruby also laughs at Weiss' small joke following their battle against Roman in his Atlesian Paladin.
In "Round One", after Weiss saves Ruby from being attacked during the match, she calls Weiss her "BFF". While Weiss refutes this label, Ruby nonetheless holds it to be true.
In "End of the Beginning" Weiss follows Ruby to find Jaune and Pyrrha showing total faith in her. Upon hearing, from Yang, that Weiss was taken away by her father, Ruby is visibly saddened.
In "Known by its Song", Ruby unexpectedly reunites with Weiss in Mistral, and they tearfully share a reunion hug together with Yang. In "Alone Together", the two of them share a great concern for Yang when she angrily states that she does not care for Blake anymore. In "Vault of the Spring Maiden" Ruby rushes to Weiss' side after seeing her injured and is relieved when she sees that her life is no longer in danger, thanks to Jaune's intervention. In "Haven's Fate" the two are fighting together against Hazel, Emerald and Mercury, before being joined by Blake.
In "Argus Limited", Ruby assures Weiss that she and their friends will not leave her side as the ex-heiress is not thrilled to be returning to Atlas. In "The Coming Storm" and "Alone in the Woods", Ruby is shocked when Weiss asks her what point is there to bring the Relic of Knowledge to Atlas after the revelation that Salem is immortal. In "Dead End", Ruby assures Weiss that their group will not leave her and that they will all get to Atlas somehow after they were turned down by Cordovin.
In "The Lady in the Shoe", Ruby coordinates with Weiss to get close to the Colossus to try and find a weakness. She is later happy when her partner saves her after being thrown off of the mech. In "Our Way", Ruby has Weiss summon her Lancer to ride on to get close to the Leviathan.
In RWBY: The Official Manga, her first meeting with Weiss is completely different than the show. She is offended when Weiss mistakes her for a child. She stands up to Weiss and calls her a stuck-up princess and a jerk, she also says that she is not cut out to become a Huntress, although Ruby later feels guilty about what she said to her. In Chapter 2, when she unexpectedly encounters Weiss for the second time, she admits she does not want to be her partner and pretended that she did not see her, but she has to learns to accept it. In Chapter 4, after Weiss saves her from a Death Stalker, Ruby inspects Weiss to make sure she is not an impostor, since the Weiss she knows is selfish and arrogant. She then thanks Weiss for saving for life. In Chapter 5, as she was about to give up after their plan failed to take down the Nevermore until Weiss tells her to come up with another plan since she is the one who started the fight and no matter how outrageous this gets, they can overcome it together.
Blake Belladonna is a fellow schoolmate and teammate of Ruby's. They have developed a strong bond as teammates, though their relationship was colder to start off with.
In "The Shining Beacon", despite helping out Ruby, Blake shows indifference to her as evidenced when Ruby tries to make conversation with her, but Blake is already walking away. That night, Blake is seen reading a book by candlelight, as Ruby is lying down talking with her sister. After Ruby pinpoints Blake, Yang pulls Ruby over to Blake to try and get them to speak to each other. Initially, this fails as Blake says she wanted to be alone to read her book, but the two find common ground over their shared love of books.
When Ruby is looking for Yang to partner with her during the initiation, she muses to herself about how Blake would be a good alternative, but that she might find it hard to socialize with Blake. Later, when observing a recent crime scene, Ruby was quick to agree with and defend Blake's statement on how it did not make sense that the White Fang would rob a Dust store, saying that it could have been Roman Torchwick, a criminal she encountered a few months ago.
After Blake implied herself as being a Faunus, Ruby tried to help her but was unable when she quickly ran out of the room, showing that Ruby cares for all her teammates. According to Ruby, she and Blake are already friends, as both already get along, although she is still quiet. Ruby also notes on how Blake's cat ears are cute.
The two seem to be on good and friendly terms, as Ruby herself was willing to help Blake in fighting their enemies. Both also seem to fight perfectly well together, as seen when fighting off against Roman, using their speed to their advantage when he piloted the Atlesian Paladin-290.
After the Battle of Beacon, Ruby is saddened by the fact that Blake ran away after the battle. Although Ruby believes that Blake might have had a good reason for running away, contrary to what Yang believes. In "Alone Together", Ruby wishes that Blake was in Mistral with the rest of Team RWBY.
In "Downfall", Ruby is surprised when she sees Blake again. But as they are in the midst of battle, she allows her teammate to head back out and fight. In "Haven's Fate", Ruby is surprised when Blake rejoins her and Weiss and asks if they are alright. After the battle, Ruby asks Blake what she is doing at Haven and later welcomes her back into the team.
In "Alone in the Woods", upon seeing Blake about to be killed by an Apathy, Ruby unintentionally unleashes the power of her silver eyes, giving her time to get the Faunus away from the Grimm. In "Our Way", Ruby is not mad and does not blame Blake after she failed to disable Argus' relay tower, she instead expresses relief that the Faunus is alright. Ruby then hugs Blake to comfort her.
In the RWBY: The Official Manga of Chapter 5, during a flashback of her discussing the plan on taking down a Nevermore with Weiss, Blake, and Yang, Ruby seems to know Blake's Semblance by a split glance at it she first met Blake at Beacon Academy.
In Chapter 7, after Weiss and Yang told Ruby about Blake, she is the only teammate who doesn't harbor any negative feelings towards Blake. She believes Blake might have a good reason why she ran off and she decides to search for Blake alone. During her conversation her with Penny, she began to have some lose some faith towards Blake since she didn't know what she will say to her when she find her.
In Chapter 8, after Ruby saves Sun from being kill by Roman, Ruby calls out to Blake, relieved that she found her. After the battle against Roman and the White fang, she asks Blake if she's alright after being hugged by Yang.
Yang Xiao Long is Ruby's older half-sister and friend. When they were young, Yang used to read Ruby storybooks filled with the deeds of great heroes, which inspired Ruby to become a Huntress. In addition, Ruby cites Yang's entry to Beacon as one of her sources of inspiration for joining the school herself.
They both attended Beacon Academy at the same time, during which Yang has shown high levels of affection for Ruby, much to her embarrassment. Despite this, from the moment they arrived at Beacon, Yang has tried to pressure Ruby into finding friends as well as a team that did not include her, in order to help Ruby be less socially awkward.
In "End of the Beginning", Ruby and Yang's relationship becomes strained after the events of the Battle of Beacon, mostly due to Yang's crushed emotional state. Although Ruby is visibly disheartened by how crestfallen Yang has become, she respects her sister's wishes to be left alone.
In "No Safe Haven", it is revealed that Ruby has been writing letters to Yang over the course of her trip to Haven, not knowing if they have reached her sister or not. She writes another letter, expressing her apologies to Yang for leaving home like she did, her loneliness without her sister and their friends, and her desires to reassemble Team RWBY.
In "Known by its Song", Ruby is unexpectedly reunited with Yang in Mistral. Upon seeing her sister, she frantically tries to apologize to her for leaving her behind in Patch. However, her apology is cut short when Yang hugs her. The sisters share a heartfelt reunion. In "Rest and Resolutions", Ruby admires Yang's new arm and cheers for her during her arm wrestle with Nora. Later, she is concerned for Yang when her older sister confronts Ozpin about his secrets and when it looks as though she is about to leave. In "Alone Together", Ruby is concerned for Yang again when she states that she does not care for Blake anymore. But she is relieved to find Yang calm after her talk with Weiss.
In "Vault of the Spring Maiden" Ruby saves Yang from Emerald and Mercury and prepares to fight alongside her sister. In "Downfall", she directs Yang to head for the vault and stop Raven and Cinder from taking the Relic of Knowledge. In "Haven's Fate", after Yang reemerges with the Relic in hand, Ruby is relieved with her safety and success.
In "Argus Limited", Ruby stops Yang from arguing with Ozpin as they have a more pressing matter of getting the passengers away from the Grimm. In "Alone in the Woods", Ruby finds herself at odds with her sister, who suggests that they leave the Relic of Knowledge in the well of Brunswick Farms so that Salem will have a hard time finding it. After accidentally dropping the lamp into the well, her anger is aroused when Yang tells her that they need to leave, causing her to shout at her sister that she's not going anywhere without the Relic.
In "Our Way", Ruby gives at a glance to Yang as she hugs Blake. As she later tries to focus her thoughts, she gets annoyed when her sister distracts her with a call and tosses her earpiece into the ocean.
In the RWBY: The Official Manga, Ruby teams up with Yang to act as baits and a distraction the Nevermore in order to buy some time for Weiss and Blake to deliver the final blow on it. In the Chapter 5, after they defeat the Nevermore, Ruby gets annoy and embarrass when Yang affectionately hug her after she was made team leader of Team RWBY. She can be seen trying to push Yang away as she continues to hug her.
In Chapter 7, Ruby looks sad that Yang doesn't want to search for Blake because she's afraid to learn the truth from her.
Jaune is a fellow schoolmate and friend of Ruby's. During the first episode, Jaune is implied to vomit near Ruby due to motion sickness.
They formally made acquaintance when Jaune helped Ruby up from the ground after she collapses upon finding herself alone. She later returns the favor in helping him to get to Beacon Cliff after he was stunned by a near-miss from Pyrrha's javelin, Miló, in the academy's locker hall.
At one point, when Yang suggests that Ruby made one friend, that being Jaune, Ruby states that Weiss counts as a negative friend and that the two balance each other out. During her race to find her sister first during the initiation test, Ruby muses that she would not mind being teamed up with Jaune because she thinks he is kind and funny, though she is not confident in his ability as a fighter.
Weeks after the Initiation, Ruby and Jaune hang out often along with their respective teams as shown in "Jaunedice". Ruby shows concern about Jaune who is being bullied by Cardin Winchester and helps Pyrrha stop Jaune from dropping the topic. After Jaune is blackmailed by Cardin, he spends less time with Ruby and she comments about it during their now unusual meeting in "Forever Fall".
Despite Jaune insisting that he is a failure as a person and leader, Ruby continues curtly contradicting him. She is shown to be confident when talking to Jaune such as her comment about him being a failure when they first met. Ruby says he has to be a better leader, otherwise, his team will fail with him, and insists that it is within his ability.
Ruby continues her friendship with Jaune throughout their time at Beacon. During Team JNPR's match against Team BRNZ in "New Challengers...", she happily cheers Jaune on. In "End of the Beginning", after the fall of Beacon and Pyrrha's death, Jaune decides to travel with Ruby to Haven to find any leads on their enemies, and for the justice on behalf of Pyrrha.
In "The Next Step", after defeating a Geist, Ruby laughs at Jaune for wearing a rabbit logo hoodie of Pumpkin Pete. She saw it for the first time after he takes off part of his armor while waiting for the Faunus blacksmith to bring his modified Crocea Mors.
In "Remembrance", she teases Jaune about how many sisters he has, giggling when he says the correct number of seven. Later, she tried comforting him in the aftermath of discovering Shion and witnessing another death. She also showed concern and respectful distance when she came across him training to a video of Pyrrha while everyone else slept.
The two remain together when Team RNJR splits up in "Two Steps Forward, Two Steps Back". Together they carry Qrow on a stretcher to get him help. When nothing is found in Kuroyuri, Ruby apologizes to Jaune, revealing that she has been burdening herself for what they are all caught up in. Jaune comforts and encourages her, listing how much she has lost and how her determination to do right inspires them to be with her.
When Jaune attacks Cinder in "The More the Merrier", Ruby attempts to come to his side before Emerald intercepts her. Seeing Jaune and Cinder charging each other scares her enough to have her flashback to seeing Pyrrha's death and activates her Silver Eyed Powers again.
In "Argus Limited", Ruby promises Jaune that she and their allies will meet up with him and his team in Argus as they stay behind to fend off the Grimm. The promise is kept in "The Grimm Reaper" and the two of them share a hug. But in "Dead End", her relationship with Jaune becomes strained as she has to yell at him to stop hurting Oscar when he thinks it's Ozpin pretending to be the farm boy. In "Lost", their relationship is seemingly restored after Ruby learns that Jaune and his team are still going to Atlas.
Overall, outside of Team RWBY, Jaune appears to be Ruby's closest friend, working together to become more than what they are. Despite both being team leaders, they are able to cooperate quite well on the battlefield, their leadership styles balancing each other out.
Although not much interaction has been shown between Ruby and Nora, their teams spend a lot of time together during their time at Beacon.
After the two form Team RNJR along with Jaune and Lie Ren, they become considerably closer. They travel to Haven together and are able to engage in conversation easily. Ruby and Nora have also been shown to fight well together, as Ruby occasionally gives Nora power-ups, such as carrying Nora by using her Semblance or shooting her friend with a blast of electricity. The two can easily agree on things; for example, they are angered by Jaune insulting Qrow.
Although the two have not had much direct interaction, the two are often seen sitting together in the cafeteria with their teams. Both girls share the same concern for Jaune, and together they attempt to make him accept the fact that he is being bullied so that he can ask for help. When Pyrrha shows up in "Round One", Ruby greets her with great enthusiasm, showing that they have formed a significant bond.
In "PvP", Pyrrha is manipulated into using her Semblance to destroy Penny. However, in "Battle of Beacon" Ruby still protects her from the Nevermore and does not blame her for Penny's death. In "End of the Beginning", Ruby swears to Nora and Ren that she will help find and bring Jaune and Pyrrha back. Ruby finds Pyrrha atop Beacon Tower and is horrified to see Cinder execute Pyrrha and disintegrate her body. Upon seeing this, Ruby activates the hidden power of her silver eyes.
After waking up, Qrow confirms Pyrrha's death, and Ruby is visibly disheartened, but she still remains stoic. As a way of honoring Pyrrha's death, she travels to Haven with the rest of Pyrrha's former team to uncover the truth behind those who attacked Vale.
In "Remembrance", it is revealed that Ruby has been having strange dreams that most likely stemmed from the night Pyrrha was killed. The dreams appeared as dark and void with silver circles floating along the sides. Despite the darkness, voices, and sometimes weapons clashing, can be heard. The most common among the voices was Pyrrha's saying Jaune's name repetitively. Ruby often wakes up abruptly during these dreams, but she does not disclose this with the rest of Team RNJR. Ruby later finds out that the dreams likely manifested due to overhearing instructional training videos, made by Pyrrha, being used by Jaune while everyone else slept. Ruby looks on guiltily at this and leaves him, keeping a respectful distance.
In "Necessary Sacrifice", Ruby states that Pyrrha was a person who took the chance of helping someone, even if that chance was small, and she died in a battle she knew she could not win. Ruby has thought of Pyrrha since her death and keeps moving forward in her memory. In "The More the Merrier", upon seeing Jaune and Cinder about to clash, Ruby remembers Pyrrha's death and cries out to stop the fight, unleashing her powers in reaction.
In "Our Way", Ruby recalls Pyrrha's death again, causing her to lose her focus to use her powers. She later focuses on the happier memories she had with Pyrrha.
Ruby and Ren originally did not have much interaction, although their teams spent a lot of time together at Beacon.
When Team RNJR is formed, they become closer despite Ren's quiet disposition. The two travel together with Jaune and Nora to Haven and are shown to get along well, in combat especially. Ruby also appears to be concerned about Ren while they are in Oniyuri. However, in "Two Steps Forward, Two Steps Back", Ruby argues with Ren about heading to Kuroyuri to find medical supplies for Qrow before Team RNJR decides to split up.
In "Known by its Song", Ruby is shown cooking alongside Ren and work together well, though she gets defensive when he critiques her cooking. In "Rest and Resolutions", Ruby notes that when Ren speaks openly that he has a tendency to become rather deep and philosophical. She also commends his ferociousness during the battle with the Nuckelavee.
In "Our Way", Ruby directs Ren to mask everyone's emotions to evade the Manticores and get to the Leviathan. She is later embarrassed when Ren praises her for destroying the Colossus' cannon and petrifying the Leviathan with her silver eyes.
Not much interaction has happened between Ruby and Cardin, but in Chapter 1 and 2 of the manga, Ruby appears to dislike Cardin for bullying Jaune. The two are then put in a duel against each other moderated by Goodwitch. At first, Ruby is nervous fighting Cardin, but she musters enough strength to defeat him.
Ruby is seen to get along well with Sun, despite having few interactions. She herself considers him a friend, as Sun thinks the same, shown in "Painting the Town..." where she did not want him getting involved in her team's investigation. Sun disagreed, saying she should always get friends involved.
In "End of the Beginning", Sun does not want her to go after Pyrrha and Jaune out of fear that she would not come back. When she goes anyway, he says that she better come back and shows that he clearly cares for her as a friend.
In RWBY: The Official Manga, Ruby saves Sun from being killed by Roman with her Semblance.
Ruby met Coco early into her first year at Beacon, where the two talked about leadership. Coco recalled the advice Ozpin gave to her and encouraged Ruby to stay on track. The two became close friends during their time at Beacon Academy. During the Battle of Beacon, Ruby advises Coco to keep her team together.
Ruby and Fox met around the same time she met Coco Adel. Fox found Ruby to be the comedic relief of her team, and shared he thought he played the same role for CFVY. The two became close friends, and comedic relief became an inside joke between them.
Ruby and Velvet appear to be on friendly terms with one another as seen in "Destiny", where they start up a conversation about Velvet's photography. Ruby hesitantly says she is getting better, indicating that the subject has come up between them before. Velvet also tries to comfort Ruby over what had happened to Yang after the match with Mercury.
Ruby encounters General James Ironwood three times, each time with him as her authority figure. The first time is just after she encounters the masked Cinder Fall in the CCT and he compliments her actions. The second time is in her dorm room when Ironwood speaks to the girls about Yang's actions and their team's subsequent disqualification from the Tournament. Lastly, she with many other students looks to him for guidance when the Battle of Beacon begins. She learns of his intention to go after his airship and get it back. When Ruby witnesses Ironwood's dropship go down, she takes it upon herself to finish his task and goes after the stolen airship. Ironwood has shown admiration of Ruby's courage and initiative in trying to stop Cinder, as these are traits that he values in all warriors, soldiers, and people in general.
Ruby first meets Winter in "It's Brawl in the Family". Winter comments that Ruby is "appropriately underwhelming", but Ruby does not seem to understand this insult. Winter then goes on to sincerely thank Ruby for "taking an interest" in her sister Weiss.
Ruby acts rather awkward around Winter in an attempt to be polite. She attempts to match her decorum and refined speech, such as using long words and phrases, and even curtseying.
When Winter gets into a fight, Ruby initially acts concerned for Winter, but once she realizes her opponent is Qrow, she quickly drops this and starts cheering for her uncle.
Upon meeting Cordovin in "Dead End", Ruby tries to "sweet talk" with her to get the group passage to Atlas, but to no avail. In "The Lady in the Shoe", Ruby destroys Cordovin's missile that was aimed at the airship, as a declaration to fight the Commander. In "Seeing Red", Ruby refuses to surrender to Cordovin and ridicules the Commander for abusing her powers when she should be protecting the people of Argus. After a failed attempt for a truce, Ruby defeats Cordovin by exploding the cannon's Dust.
In "Our Way", Ruby thanks Cordovin for saving her life and apologizes for stealing her airship.
The two first met indirectly during a dust store robbery, where she fought Ruby from an airship and defended herself from Ruby's Crescent Rose ammunition. Around the time of the Vytal Festival, and the beginning of the second semester at Beacon, the two meet again, for the first time face to face. Cinder claims she is visiting from Haven, alongside Emerald and Mercury. Ruby, unaware that Cinder was the one helping Roman before, redirects them to the building they are supposed to go. Cinder thanks her in response, saying they will see each other around. Ruby amicably agrees.
Later, in "Dance Dance Infiltration", the two fight again for a brief moment, Ruby not recognizing Cinder due to the latter wearing a mask. However, the encounter reached an abrupt halt upon the arrival of James Ironwood, which gave Cinder the opportunity to flee. However, in "End of the Beginning", Ruby finally sees Cinder for what she is, and is horrified as she watches her kill Pyrrha. The emotional turmoil causes Ruby to unleash the hidden power of her silver eyes, shocking Cinder as a white light envelopes her. When Qrow tries to have Ruby remember that night, Ruby begins to remember Cinder and is angered by what had happened.
In "The Next Step", it is revealed that Ruby severely crippled Cinder, robbing her of her left eye and voice. As with Cinder's antagonism towards Ruby, Ruby's antagonism toward Cinder is mutual and is evident in "Tipping Point".
Cinder's ruthlessness terrifies Ruby, who is according to Blake, "the embodiment of purity." However, Ruby is determined not to draw power from her sorrow, as was implied in her letter to Yang, in contrast to Cinder, who is motivated by revenge for her defeat and disfigurement by Ruby's powers.
Cinder's murder of Pyrrha Nikos seems to have left Ruby with a degree of post-traumatic stress, as seen during Cinder's duel with Jaune at Haven in "The More the Merrier". The battle forced Ruby to flash back to Pyrrha's murder, causing her to momentarily engage her silver eyes' powers in reaction.
Ruby initially believed that Emerald was her friend, and acted friendly towards her whenever they met. However, Emerald is actually simply manipulating Ruby and finds her constant cheerfulness aggravating.
The two first met in "Welcome to Beacon", when Ruby accidentally bumped into her while running to the library to retrieve her board game. Emerald helps the latter up after she fell, telling Ruby to mind where she is going. Ruby then redirects Emerald, Mercury and Cinder to their respective building.
In "Extracurricular", Emerald is seen putting on a friendly act around Ruby, smiling sweetly when she speaks to her, but scowling and rolling her eyes as soon as Ruby looks away.
In "Breach", after the battle, Emerald briefly joins Ruby and the rest of her team in celebrating their victory.
In "Round One", Ruby and Emerald greet each other amiably and share a pleasant conversation, and Ruby even invites her and her team out to lunch. However, once their backs are turned, Emerald expresses her intense dislike for Ruby and her team to Mercury, claiming that she cannot stand their constant positivity. Evidently, she only tolerates their presence due to being on a fact-finding mission for Cinder.
But in "Destiny", Ruby begins to become suspicious of Emerald and Mercury after learning of Coco's "hallucinations" from Velvet. Her suspicions are confirmed when she spots Emerald inside the Amity Colosseum, contrary to reports of her returning to Haven with Mercury.
When they encounter each other again and fight in "The More the Merrier", Ruby questions why Emerald is serving Salem, to which she finds that Emerald is serving Cinder out of debt. In "Haven's Fate", Ruby fruitlessly tries to persuade Emerald and her allies to stop fighting as everyone is clearly worn out from the battle.
Although they have not interacted much, Ruby was the one who redirected Mercury along with Emerald and Cinder to their location within Beacon, after claiming they were lost. She herself is also impressed by his combat abilities, seen in Mercury's fight with Pyrrha.
In "Destiny", Ruby sees Mercury's true colors after she becomes suspicious of him and Emerald. She encounters him in the stadium's maintenance hall in fighting form, despite him supposedly having a broken leg and allegedly returning to Haven.
In "Downfall" Ruby head butts Mercury during their battle, vowing to do whatever it takes to silence him.
Although the two interacted only five times, Roman had a clear dislike and hostility towards her. The two first met when she foiled a Dust store robbery prior to her enrollment at Beacon.
They met again in "Black and White." Their confrontation was short because he instantly attacked her, rendering her unable to battle and prompting Penny to fight in her defense.
Once again, they met in "No Brakes", where he enjoyed toying with her. Her attempts to escape all failed until the arrival of her team. Roman ordered the White Fang to kill her, shooting at her as well, further demonstrating his hostility.
They fight for the final time in "Heroes and Monsters" on top of a hijacked Atlesian airship. Their differences in their beliefs were made perfectly clear: while Ruby believed that she and her allies will stop Cinder's faction and protect the world, Roman proclaimed that Huntsmen like her will die and dishonest men like him will survive. However, he was eaten alive by a Griffon in an ironic twist, and Ruby did not show a single shred of remorse or sadness for his death.
Months later, when she and her team are ambushed by Tyrian Callows in Oniyuri, she asks the tracker if he has come on Roman's behalf, indicating she has not forgotten her old enemy.
Although the two have not officially met, Salem is fully aware of Ruby's powers as a Silver-Eyed Warrior. She considers the girl a threat to her plans, arranging for Tyrian to capture Ruby rather than the Spring Maiden, though she does not elaborate on why she wants the girl alive. In "Punished", Ruby hears of Salem for the first time through her uncle Qrow, when Tyrian reveals that "the queen" sent him to fetch her.
In "Necessary Sacrifice", Ruby states that she is afraid of Salem for her willingness to kill both her enemies and innocent bystanders. In "Haven's Fate", Ruby is confronted by an enormous illusion of Salem created by Emerald's breakdown. This leaves Ruby utterly terrified.
In "The Lost Fable," Ruby witnesses Salem when she was still human, along with her fall into darkness from a failed suicide attempt, courtesy of Jinn's storytelling. When she learns that Salem cannot be killed, Ruby is shocked silent.
Salem arranges for Tyrian to find and capture Ruby. Tyrian, though briefly dejected that he is not supposed to kill her, quickly becomes gleeful and anxious to begin the hunt. He strongly hinted that he's willing to destroy one of Ruby's eyes in the interest of avenging Cinder's crippled one. Tyrian tracks Ruby to Oniyuri, where he reveals his plans to capture her.
The battle concludes when Ruby cuts off Tyrian's stinger after Qrow is struck with it. The dismemberment elicits Tyrian into calling her a bitch.
Penny is seen to be a good friend of Ruby, despite the two only meeting in "The Stray". In "A Minor Hiccup", having not seen each other in weeks, Penny acts as if she does not know Ruby. However, due to Ruby's persistence, Penny gives several excuses or reasons, but she eventually says that she was told not to talk to Ruby.
Shortly after Penny saves Ruby from an oncoming truck, Ruby tells Penny she can trust her and that they are friends. Penny then reveals that she is not a real girl, but she is a synthetic person who can generate Aura. Despite this, Ruby still considers her a 'real' person and promises to not tell anyone else Penny's secret.
In "PvP", Ruby is devastated over Penny's death, dropping to her knees and sobbing at the loss of her friend. At the start of "Battle of Beacon" despite the chaos happening around her, Ruby is momentarily in a state of shock.
In "Necessary Sacrifice", Ruby states that Penny was killed just to make a statement and that she has thought about Penny ever since the Fall of Beacon. She also states that she is fighting Salem because she knows that Penny would have done the same for her.
In "Our Way", Ruby remembers Penny's death, which causes her to lose her focus to harness her powers. After she regroups herself, she recalls happier memories with the robot.
In Chapter 6 of RWBY: The Official Manga, after she accidentally bumps into Penny when she was trying to chase after Sun, she felt very disturbed and uncomfortable around Penny due to her strange behavior. She does not like how Penny gets too close to her personal space when Penny asks her if she can be her friend. Ruby is unable to say no to her, resulting in her unintentionally becoming Penny's friend.
In Chapter 7, Ruby grows used to being comfortable taking to Penny after having teatime with her. She is willing to talk to her about Blake. In Chapter 8, Ruby expresses concern and worries for Penny when she somehow got on top of the White Fang's airships. She is also amazed by Penny's combat skills on taking down most of the White Fang's airships on her own without any help.
Ruby meets Oscar in "Welcome to Haven", and is perplexed when he points out her silver eyes. After discovering that he has Ozpin's soul within him, however, she warms up to him and shares friendly conversations.
In "Unforeseen Complications", Ruby giggles at Oscar while they are getting to know each other, prompting Oscar to awkwardly blush at her. In "Lighting the Fire", Ruby spars with Oscar and later shows encouragement in finding his Semblance.
In "Necessary Sacrifice", Ruby shares with Oscar the fear she has for Salem and the sorrow she endured after losing Penny and Pyrrha. She also acknowledges him for his bravery and perseverance.
In "So That's How It Is", Ruby tries to comfort Oscar by saying that he is his own person, only for her efforts to be thwarted by Qrow. In "Dead End", Ruby is shocked to find that Oscar has gone missing after he was assaulted by Jaune. In "Lost", after conducting a search for him, Ruby is relieved to see Oscar safe back at the Cotta-Arc house and compliments him for his new combat gear. In "Our Way", Ruby hurriedly praises Oscar for him keeping their airship safe from a crash land so she isn't the only center of attention for the others.
Ruby summons Jinn from the Relic of Knowledge by following Oscar's instructions. She asks what Ozpin is hiding, and the magical being responds by revealing the distant past of Remnant, when Salem and Ozpin, then known as Ozma, first met. In "Our Way", Ruby summon Jin out of panic and she apologize to Jinn that she does not have a question for her and she need time to use her powers.
In "Alone in the Woods", Ruby learns how to properly utilizes her powers as a silver-eyed warrior from Maria, and later leaves the elder in awe after she destroys the pack of Apathy. After they leave Brunswick Farms, Ruby learns that Maria was a former Silver-Eyed warrior herself. In "The Grimm Reaper", after learning of Maria's past, Ruby asks for training to properly use the power of her eyes. In "Dead End", Ruby learns from Maria more of the elder's past and gains a better understanding of her powers.
