Nyssa al Ghul

"We have unfinished business, sister."

- Nyssa to Talia al Ghul

Nyssa Raatko (Arabic: نيسا رعتكو‎) (born May 10, 1985), better known as Nyssa al Ghul (Arabic: نيسا الغول), is a former member of the League of Assassins and an ally of Team Arrow. Nyssa is also the daughter of the late Ra's al Ghul, the paternal younger half-sister of Talia al Ghul, the legally invalid wife of Oliver Queen, the ex-lover of Sara Lance, and the former mentor/close friend of the late Laurel Lance. She was the one who brought Sara to Nanda Parbat. She was briefly "Ra's al Ghul" and the last person to have the title, making the personal choice to disband the League of Assassins and destroy the ring of Ra's al Ghul.

Early life
Nyssa was born on May 10, 1985 to Ra's al Ghul and one of his concubines Amina Raatko. She was raised in the League of Assassins, becoming a proficient swordswoman by 8 years old. Nyssa was apparently in line to succeed Ra's al Ghul in the event the prophecy of someone surviving a battle against him didn't come true. Nyssa loathed her father from a very young age and lived in constant fear of him and grew a burning desire to kill him one day and take his place, but nevertheless was proud to be daughter of the demon. In her youth Nyssa was very mischievous and often stole extra meals and hid them in her room until later times, but Ra's would always find her hiding spots. Nyssa would eventually learn that she could hide nothing from Ra's.

In 1993, Nyssa brought in Malcolm Merlyn to be trained as a league member. In their initial meeting, Nyssa named Malcolm "Al Sa-Her" (Arabic for "Magician") after he pulled a coin out of her ear in a magic trick.

On her father's beheast in October 2008 Nyssa traveled to Lian Yu and she met a dying Sara Lance, almost dead from starvation and seemingly given up on living. This unknowingly was orchestrated by Sara herself when a future version of her told her father back in 1960 to send Nyssa to Lian Yu to find her younger self after she was shipwrecked after the Queen's Gambit was sunk. She took Sara in and nursed her back to health and in return for Nyssa's compassion Sara decided to join the league. However Ra's never saw Sara worthy enough for the league as Sara never fully renounced her past life, as part of the league's code, and still remembered who she was and where she came from, and Ra's even tried to make Sara leave with a demonstration of his power. However Sara simply laughed whereas others had quaked in fear and from this points on Nyssa deeply fell in love with Sara and at some point, Sara begun to return the affection and they became lovers. Ra's however never approved of Nyssa's relationship with Sara as he saw Sara as weakness to his future heir and knew that Sara would leave the league, either by choice or by death.

In 2013 following Malcolm Merlyn's undertaking Sara left Nanda Parbat to check on her family but failed to return after several weeks and Nyssa eventually learned that she'd refused to return home. Following this Nyssa set out to find Sara and use any means to find her beloved.

Looking for Sara
Nyssa arrived in Starling City to find Sara Lance. A scan of her passport declared her an active A.R.G.U.S. threat and agents attempting to detain her were met with brutal force at her hands. Following this she quickly left the airport.

Nyssa eventually found Sara, and kissed her much to Oliver's surprise when he was watching. She revealed she hadn't decided which she would do, also indicating that she knew Oliver was with them. Sara asked Oliver to let her handle Nyssa. The two walked away and discussed their former relationship. Nyssa expressed how hurt she was that Sara had just left her without saying goodbye. Sara responded to her with warmth and feeling, apologizing. She begged Nyssa to release her from the League just as Ra's al Ghul had done previously with Malcolm Merlyn, but Nyssa brushed this off as a horrible one-time mistake. After sharing another close moment, Sara told Nyssa she wouldn't go back, and to do what she had to. Sara stood waiting as Nyssa drew her dagger from her thigh. A surprise to her, Nyssa wouldn't kill her, leaving.

Later on, a member of the League kidnapped Sara's mother Dinah Lance, working with Nyssa. Oliver and Sara tried to stop them as they drove away, however Nyssa drove them back with a deadly stream of arrows. Nyssa called Sara, telling her that she had 24 hours to rejoin the League or Dinah would die.

It is revealed Nyssa tricked Sara into coming back to Starling by poisoning Laurel Lance with snake venom, and having witnessed the other League member kill himself earlier, Sara decided to take his poison vial and told Nyssa she would rejoin the League. Upon arriving with her father, Nyssa released Dinah. She was happy to see Sara back, only to be shocked to see Sara had taken the poison. This sent Nyssa into a despairing rage. When Sara's parents arrived she immediately and swiftly disarmed Quentin and was about to kill them before being blocked by The Arrow. The two engaged in archery and hand-to-hand combat where Nyssa disarmed and almost killed Oliver with her dagger. However Oliver managed to trap her in a chokehold. As this happened, Sara struggled towards them, begging Oliver to spare her former lover. Oliver hurried to Sara's side, saving her with the herbs taken from Lian Yu. Touched by Sara's would-be final act, Nyssa declared Sara free from the League. As the police arrived, Nyssa was nowhere to be found.

Sara later contacted her and agreed to join the League again if Nyssa would help save Starling City. Nyssa and a group of League members joined Oliver's team and armed themselves with arrows containing the Mirakuru cure to combat Deathstroke's soldiers, and to cure the Mirakuru serum in their bodies. Oliver instructed Nyssa and her group that no one should be killed. They then confronted Slade in his office and beat all of his soldiers while he managed to escape. Nyssa and Sara managed to quickly take out Isabel Rochev who began to mock Oliver. Although technically acceding to Oliver's demand that there be no killings, Nyssa herself delivered the coup de grâce on a disarmed and neutralized Isabel Rochev, telling Oliver that "your reticence to do what is necessary is why your city burns". The group then went to the tunnel to engage Slade's Mirakuru-infused thug army. The group used their archery and close combat skills to beat the soldiers. Nyssa personally made several shots during the melee in the tunnel which saved Oliver and Roy. When Slade's plan had been derailed, Nyssa swore to Sara's father, Quentin Lance, to keep Sara safe. She then took a willing Sara away with her on a ship to rejoin the League.

Hunting Sara's killer
Upon Sara's disappearance, Nyssa storms into the Arrowcave, aiming an arrow at Oliver. Oliver informed her of the death of Sara. Shocked with grief, she revealed that Malcolm Merlyn was still alive and that Sara had come to Starling City to trace a rumour that he was here. She visited Sara's grave where she meets Laurel, she swears a blood oath to avenge Sara's life using the Arabic Words "أقسم بحياتي", which mean I swear on my life, the rest of the oath is undistinguishable. She went to Sara's safehouse where she and Oliver found pictures and notes Sara had made while investigating Malcolm. Team Arrow and Nyssa found out Merlyn was hiding in a Buddhist temple. Infiltrating the temple she confronted the leader who was meditating (unaware it was Merlyn, as the leader had passed away years ago). Realizing it was Malcolm, she tried to kill him however he incapacitated her easily and fled the scene. Oliver managed to put a tracker on him. Nyssa was angry at Oliver that he did not attempt to kill him. After learning Oliver had talked to Malcolm and did not believe he killed Sara she became furious at him. Learning Thea was actually his daughter, she kidnapped Thea. Trying to lure Malcolm in, Oliver freed Thea and the two started a fight. Merlyn showed up and a wild melee started in which Malcolm managed to overpower Nyssa, and told her he did not kill Sara and suspected her own father Ra's al Ghul to be the killer. After a discussion. Oliver refused to kill Malcolm, and told Nyssa he would not allow the League of Assassins to come near him. Angered by Oliver she shared her thought with Laurel and encouraged in her training to become stronger before leaving Starling City. She was later shown informing her father, who assured her Malcolm would face justice. She did appear to have doubts about Malcolm's guilt in Sara's death, especially when her father stated that Sara "was never truly one of us". Upon hearing of Oliver's decision to protect Malcolm, he declared war.

She later left to Starling city with a group of assassins and captured Oliver. She informed him that he had 48 hours to find Sara's killer or the League would start killing citizens. After this she was present when the deadline had passed and her father talked with Oliver. Oliver said he had killed Sara which made her react in disbelief. Oliver lied that he killed her because she begged him as she did not want to return to the League. He then challenged her father for a trial by combat which he accepted. She was present on the mountain where Oliver and her father would have the duel. She said she envied Oliver as he would see Sara soon (in death). Her father engaged Oliver in combat. Being unarmed Ra's easily dodged Oliver's sword strikes. He ultimately mortally stabbed him and threw him off the mountain.

Nyssa later confronted her father about that Oliver is still alive. Her father said he was aware and he also knew that Oliver did not kill Sara. Nyssa questions if he ever approved of her relationship with Sara. He said he knew their love would only end in heartbreak. Nyssa mentioned that even if Oliver did not kill Sara he still deserves to die for defying her father. Nyssa and a group of assassins went to Starling City as they looked for Malcolm Merlyn, they got contacted by Thea who offers them Malcolm Merlyn in return for safety. Nyssa agreed and Thea tells them where Malcolm is. Nyssa and her team find Malcolm as he is getting attacked by Laurel. He easily fended her off and took her baton, after which she pulled a gun on him. Her assassins quickly disarmed Laurel and surrounded Malcolm. Nyssa faced Malcolm in a duel while she used her scimitar and he used the baton of Laurel. After a short fight she managed to overpower him and knocked him out. Preparing to leave by helicopter Nyssa told Malcolm he would suffer for what he did. Malcolm replied that her father only wanted to punish him for the undertaking and the he never cared for Sara. Malcolm said her love for Sara made her unable to take the place of her father. Oliver Queen came to his rescue. Nyssa ordered her men to leave with Malcolm while she prepared to hold Oliver off. She fought Oliver however he managed to tie her up with a trick arrow and capture her. As the helicopter flew Malcolm away she mentioned to Oliver that Malcolm will never be seen again. Nyssa got locked up in a cage in the Arrowcave. She spend her time meditating as Oliver and his team discussed what to do. Oliver send the rest away as he asked her where Nanda Parbat is. Nyssa explained that every action of him had frustrated the vengeance for the death of Sara, and she tells him the location as she is certain he will die there. Laurel later brought her water and Nyssa said Malcolm will get tortured by her father, but Laurel does not seem please how the killer will be punished. Laurel said she hated Merlyn and that he was like a piece of Sara that still existed. However now he is gone she can not even remember the sound of Sara her laugh. Nyssa told her that the first time Sara was brought to her father she was the witness of a demonstration of his power, however she simply laughed as she was completely innocent. It was that moment Nyssa fell in love with her. A touched Laurel thanks her for sharing this. Thea later visited her at her cage as she explains she can not live with the guilt of what she did. Thea explained to Nyssa that she lied to her and that she was the one who killed Sara. Thea then opened the cage door and hands Nyssa her scimitar as she says she can have her revenge.

Nyssa took the scimitar but refused to kill Thea. A frustrated Thea explained how she killed Sara while being drugged. Nyssa said that the murder will be revenged with the death of Malcolm. Laurel and Roy came in and attacked Nyssa as they believed she had escaped. Nyssa knocked them both down but was shot with an anesthetic and passed out. Locked up in the cage she was surprised when Oliver returned and set her free. She demanded explanation as she refused to believe her father had let Malcolm go. Oliver told her to just go home.

When she arrived at Nanda Parbat, her father said coldly he was happy to see her again. She demanded to know why he had let Malcolm go. Her father explained it was a favor to Oliver as he would become his heir. Nyssa said it was because he did not approve her relationship with Sara. Her father explained how she was unfit to be his heir as she had allowed weakness to come into her life which had made her emotional in her judgement. Nyssa attempted to kill him with a sword strike which he easily blocked. Nyssa said she would not watch her legacy being given to an outsider and left.

Leaving the League
Nyssa later came back to Starling City and saved Laurel as the police station was under attack by Murmur. Killing multiple gunmen she then left the scene. Nyssa later talked to Laurel and told her Laurel reminded her of Sara. Nyssa asked Laurel if she would like to talk about her father as they both had some issues with their fathers. Laurel agreed and they went to dinner while Nyssa complimented her fighting skills and offered to train her as she would stay in Starling City for a while.

She met with Oliver in an alley as he asked for her help. She refused to betray her father which resulted in him bringing up Sara. She then gave Team Arrow the location of a building that the league has been using has been using as a staging ground. Nyssa then showed up and helped Laurel when she was cornered by her father.

Nyssa continued training Laurel. She made Laurel track a criminal. When Laurel and the criminal fought and he started to overpower her Nyssa swiftly intervened and took him out. Nyssa showed Laurel that the criminal was carrying two knives and the two then went to get a milkshake.

When drinking their milkshake Nyssa was surprised with the fries and the talked about how they enjoyed spending their time together. Nyssa mentioned she enjoyed the last few weeks and thanked Laurel for being kind to her after being subjected by her father. Laurel mentioned she had to tell Nyssa of how Oliver was now with the League. Nyssa mentioned that Laurel should not have hidden that from her and angrily left the restaurant.

Laurel met Nyssa at her hideout and told her she was sorry for not telling her however she did not wanted to upset her while she seemed so happy these last two weeks. Nyssa told Laurel she should not keep secrets especially after her relationship with her father suffered because of her secrets. Nyssa told Laurel she should stay away from her as Oliver and the League will come for her now that he has become the heir.

Nyssa and Laurel went to John and Felicity and told them that Oliver was brainwashed and is no longer the person they knew him to be. John and Felicity mentioned they could not believe it and Nyssa told them she was damaging the memory they had of him. She told them she would not hide and she would face him and accept her destiny.

Nyssa went to the rooftop where Sara got killed. Oliver showed up and she asked him if he still remembered her or if his memory of her had been destroyed by her father. Oliver told her she had to come to Nanda Parbat. The two attempted to shoot each other, however both managed to dodge and block the arrows. Nyssa and Oliver then fought each other using their bows and swords. After a short fight Oliver quickly disarmed her and knocked her down. Before he could kill her Laurel and John stopped him. As they told him to back off Oliver quickly escaped the scene by jumping of the roof.

At her hideout Nyssa nurtured her wounds and told Laurel she should not have intervened. Laurel mentioned she did not want to lose her as well after all the people she lost. Nyssa mentioned that the last few weeks she realized there was a life outside of the league however as daughter of the Demon that life would never be for her. Laurel mentioned that she did not recognized Oliver when he fought Nyssa. Nyssa mentioned he has changed, however Laurel mentioned that she could change as well.

John and Felicity visited them and told them Lyla had been captured to force them to surrender Nyssa. Furious John scolded Nyssa and the League for their lack of honor. Laurel tried to calm him down however he wanted Nyssa to surrender to the League. Nyssa told them she will give herself up however Laurel told them they would lose their soul if they would surrender her to get Lyla back. Nyssa, Laurel, John and Felicty met with Oliver and the Assassins. Oliver ordered Maseo to search them for weapons. Felicity refused to be touched and Oliver made Maseo back off. Oliver ordered Nyssa to be bound and then released Lyla. Maseo ordered Nyssa to kneel before Oliver however she refused. Lyla grabbed two guns hidden on Felicty and quickly shot two assassins. In the ensuing fight Nyssa took out two guards and managed to break her bonds after which she took a sword. She fought Maseo in single combat while Team Arrow quickly got overpowered by the Assassins. When Laurel got overwhelmed Maseo quickly subdued the distracted Nyssa and captured her. Nyssa then got dragged away by the assassins.

When brought before her father he told her about how she used to steal during meals but that he always found out. He then unlocked her sword and found the Omega virus. Ra's told her he would try to remember her as she was before she left the League. Nyssa mentioned that her whole life she had been afraid of him but she was not scared of him anymore. Ra's ordered Oliver to kill her but stopped him at the last second. He congratulated Oliver for overcoming her and said that her death would serve no purpose. Learning he wanted her to marry Oliver, Nyssa mentioned she would rather die. However Ra's said she had no choice in the matter. He told her that she will marry Oliver and she would become Bride of the Demon.

Later she was brought before her father and Oliver for dinner, Ra's decided that he wanted the title Ra's to be in the family line and so he wanted a grandchild so he told Nyssa to get pregnant with Oliver's child, a decision that she was visibly displeased by. Later her father met her in her room and told her to be respectful to him but instead she scoffed at him. Her father had brought in a necklace that belonged to her mother and told her about how he met her, when she refused to marry Oliver, he held her face in a threatening matter and forced her to marry Oliver. After Oliver's team was captured and infected with the Alpha Omega virus, she married Oliver and the "union is sealed" as said by the Priestess.

When Ra's put his plan into motion which was to infect Starling City with the Bio-weapon, she was put on the plane and guarded by several members of the league. The plane was later sabotaged and Nyssa looked confused, Ra's was about to kill his own daughter when Oliver revealed his deception, he gave his sword to Nyssa and she killed the majority of the men on the plane. Ra's, unfortunately escaped with the canister with the only parachute and they landed the plane safely in the forest. They infiltrated Palmer Technologies and gave the group a scare, she held the group at bow-point but was brought down by Oliver, Oliver was later knocked down by Diggle and she raised her bow at him again to protect her new husband but was again brought down by Oliver.

Later when the group formed a plan, she went with Laurel to take down another member of the League and despite not being inoculated, she went along with the plan saying "This is my father's doing, I will see it undone". After this she parted ways with Oliver to Nanda Parbat. Nyssa returned to Nanda Parbat where she discovered Malcolm had become the next Ra's al Ghul, with his proof of ascension being that he was tortured by Ra's sword and he survived also stating that he wanted to escape Ra's just like she wanted, Nyssa stated she hadn't forgiven him for what he had done and vowed that she would have justice. Malcolm welcomed her to try and she was forced to kneel in front of him along with the other dozen members in the room.

Disbanding the League
Malcolm and Nyssa were sparring before Laurel and Thea arrived in Nanda Parbat to try and convince Malcolm to use the Lazarus Pit to resurrect Sara which Malcolm refused and Nyssa agreed to with his decision. Nyssa later explained to Laurel that using the pit has serious consequences and her father paid a dark price for using the pit and she didn't want to see Sara go through that pain. After Malcolm finally agreed to use the pit on Sara, Nyssa furiously barged in and told Laurel that all that was happening to Sara was her responsibility. Nyssa later destroyed the pit and was taken away by Malcolm.

After she was held prisoner, she refused to eat anything, only waiting for the correct time to strike against Malcolm and his men, all the while asking Talibah to assist her in gathering loyalists for her war against Malcolm. During her imprisonment Nyssa stunned to be visited by Sara whose soul had been restored, and was overjoyed to see her beloved again. Sara promised she'd find a way to get her out of Nanda Parbat but Nyssa reminded her, that her own actions led to her predicament. Nyssa also told Sara that if she did truly still love her then she would leave and never look back, and find a new life for herself united to her past. Tearfully Sara agreed and the former lovers hugged one last time before she left.

Nyssa eventually escaped from Nanda Parbat with the help of an assassin Talibah, who slipped a key to her via a hollowed out pepper in her dinner. The pair searched for the Lotus in Kyushu, guarded by Tatsu Yamashiro. Tatsu and Nyssa found their skills to be too evenly matched for an outcome and Nyssa gave the option to keep fighting or give up and listen to the news she had on a situation concerning Oliver. Later that night, Nyssa showed up at Thea's hospital room offering Oliver the Lotus elixir, which counters the effects of the Lazarus Pit, on the condition he kills Malcolm.

After Laurel was tragically killed by Damien Darhk Nyssa returned to Star City to pay her respects. However Nyssa grew concerned when Quentin asked if there was any way to bring her back i.e. the Lazarus Pit, but Nyssa told him she'd destroyed it and there is no other means to bring Laurel back. Concerned for Quentin's well-being Nyssa approached Oliver and asked him to speak to Quentin, to convince him he's in denial and needs to embrace the grief. Later Nyssa attended Laurel's funeral along with Diggle, Thea, Felicity, Quentin, Dinah and Oliver before leaving Star City yet again.

Altered reality
In a reality created by Eobard Thawne using the Spear of Destiny, Nyssa's life was drastically altered. Her life had been changed so that she was living a "miserable closet life" in Ohio courtesy of Malcolm Merlyn and the spite that he had for her.

A matter of family
In May 2017, Nyssa was contacted by Oliver to help defeat Adrian Chase/Prometheus, although Malcolm was oblivious at first, but accepted it after some persuasion from Oliver, but revealed that she would be fighting against Chase's mentor Talia al Ghul, which was also her paternal half-sister. The trio then flew to Lian Yu where Chase was hiding. Nyssa also briefly mentioned that her father, Ra's al Ghul sent her to the island 3 years ago where she found Sara.

On the island, Nyssa had intercepted Talia, who taunted her sister for her foolishness for giving up the mantle of Ra's al Ghul and stated she only left because it became clear that her father would never pass on the title to a woman including his daughter, but Nyssa blamed her for selfishly abandoning her to suffer at the hands of her father when she needed her most. Even though Talia expressed how Nyssa brought shame to their father by aligning with Oliver, Nyssa simply stated that she was fighting alongside her friends and that Ra's from the very beginning has always been ashamed of her. Nyssa then dueled and defeated her sister, but as Talia's acolytes lunged at her, Slade had arrived just in time to slaughter them. As Nyssa held her sword to her throat, Talia taunted her into killing her by stating Ra's al Ghul's approval, but as Nyssa couldn't bring herself to do it, she knocked her unconscious. She then assisted Team Arrow and Deathstroke in defeating Talia's acolytes with Adrian Chase and like everyone else, she was shaken when Chase stated Oliver's son was dead.

Chase rigged the island with explosives, with his death as the trigger, and he eventually shot himself in the head, committing suicide and destroying the island, with Nyssa still on it.

Slade later told Oliver that Nyssa had survived, as she was taking shelter with the other survivors on the plane before going off to search for Evelyn Sharp.

Personality
In the heat of battle, Nyssa shows a cold demeanor and a cold blooded killer side. When not in the heat of battle, contrasting what people would expect from her being in the League of Assassin as well as Ra's Al Ghul's daughter, Nyssa shows a warm, kind, and caring side to those she loves such as her friends such as Laurel alongside Team Arrow, and her love interests such as Sara.

Her pain is evident in her first appearance, heartbroken that Sara had left her behind. She was more upset over this than any apparent betrayal of the league. She refuses to kill Sara, even when she is offered the opportunity to do so. She finds herself stricken with grief when she discovers that Sara had poisoned herself, rushing to her aid and crying. An ultimate act of "kindness" on her part was releasing Sara from her allegiance and oaths to the League as well as the threat of the League of Assassins; touched by Sara's undying care for her as the woman begged the Arrow not to kill her; despite being on the verge of dying herself. Her "friendliness" is also show in her debut; giving a warm smile and a playful wink to a young boy waiting in line near her at the airport. Nyssa also seems to be very moral as she simply subdued the guards that tried to arrest her during her debut and didn't involve innocent people and simply made her way out after she subdued them.

Nyssa can be just as cold as any other member of the League of Assassins. She acts more so out of personal vendetta than loyalty to the League. She wouldn't kill Sara, but she resorted to kidnapping her former lover's mother in retaliation. She delivers an ultimatum, declaring that she would show Sara how it felt to have someone she loves taken from her if she doesn't return. This act of vengeance for Sara leaving her continues. She feels once again abandoned when Sara would rather die than return to the league, and to her. She declares that if this were to be the case, she would kill Sara's family. However, she quickly abandoned this when she realized Sara would rather die than return to the League and chose to free her rather than letting her die. This implied she still cares for Sara despite them no longer being lovers. Even when Sara agreed to return to the League of Assassins in exchange for them helping subdue Slade's army, she told Quentin Lance she would die before she lets Sara die.

After Sara got killed she became furious and was convinced Malcolm was the killer. In the process she even abducted Thea to draw Malcolm out. When Oliver didn't believed Malcolm did it she quickly considered him an enemy as well, and was prepared to kill him. She had a deep hatred for Malcolm as she was convinced he had killed Sara despite him swearing on his daughter he wasn't responsible, it was later revealed she was partly correct as he had drugged Thea and had her kill Sara.

At first Nyssa didn't like Laurel and mentioned she wasn't worthy to wear the jacket of Sara. She later changed her mind and mentioned Laurel reminded her of Sara and was friendly with her even after she considered Oliver an enemy. Nyssa later shared memories with Laurel about Sara and later even asked her to dinner and offered to train her.

Nyssa is shown to be knowledgeable of cultures and respectful even when she is on a vendetta. This was shown when she referred to "Jansen" with the honourific "sensei" before threatening to kill him over Malcolm's location.

Despite her intelligent and calculating personality, Nyssa is prone to allow herself to be emotionally blind, especially when it comes to Sara. She even tried to attack Ra's al Ghul in a fit of rage upon learning he denied her what she believes to be her heritage. According to Malcolm, Nyssa's ultimate dream was to succeed her father, which she lost all chances of doing when she chose a relationship with Sara. Nyssa believes this as well and believed Ra's making Oliver his successor was a way to punish Nyssa (however, this is untrue as Ra's' reasons for making Oliver his successor, is because he survived his blade, and because Nyssa has proven herself unfit to become the leader of the League as she has time and again proved that she allows her emotions to cloud her judgment). Nyssa is not always without compassion or reason however. She did spare Thea for physically killing Sara since she was mind controlled by Malcolm to do so. She also put down the sword Thea gave her to subdue Roy and Laurel non-lethally rather than going for lethal methods.

While not completely explicit, her animosity towards Oliver might be lessening, as she has shown multiple times that in, she trusts and cares for him. Examples include when she willingly listened to his every word when they crashed the plane; her immediately raising her bow to defend her new husband when Diggle punched Oliver to the ground; and later when she treated his sword wound after his battle with Ra's. Notably, Nyssa held no ill-will against Oliver when he killed her father despite wanting to do it herself and even quickly changed the subject to his surviving getting shot due to his League armor, conveying a warm smile during which. Despite not being together, she still sees Oliver as her husband and Thea as her sister-in-law. This is also further proven that they both care about each other when Oliver requests they use an ancient set of rules so that he would have to face Malcolm, rather than Nyssa. Nyssa has demonstrated that though she can be emotionally blinded by her desires she is capable of change as she realized from Laurel's advise that she was turning into her father in her quest to remove Malcolm from his throne, and rather than continue the league's ways she used her newfound authority as Ra's al Ghul to disband the League of Assassins and parted with Oliver and Laurel on civil terms.

She has grown to care for Oliver and his team, having gone through the trouble of coming to Oliver to help him when he reached out to her. Even going as far as to calling them her friends and that she stands with them when her sister questioned her resolve for allying with their father's murderer.

Despite being forced into their marriage, she still acknowledges Oliver as her husband, even though she does not love him like one, implying that she still commits to vows. This seems to be in an effort to embarrass Oliver as she even told Slade Wilson about their marital status, causing Slade to question Oliver's love life.

Trivia

 * Nyssa's encounter with Sara, and being given her name, is the result of a time loop. This is due to the 2016 version of Sara being stranded in 1958 and joining the League of Assassins, then being released in 1960, but tells Ra's he'll have another daughter named Nyssa, and to send her to Lian Yu in October 2008 where Nyssa meets Sara's younger self who will carry out the same actions.
 * After being forced to marry Oliver Queen by Ra's al Ghul, she has often referred to him as her husband, acknowledging their marriage beyond formal necessities and even going so far to call Thea her sister-in-law. However, Oliver has only claimed her as his wife once or twice during important ceremonies. Even after the League of Assassins was disbanded, Nyssa still refers to Oliver as husband when they next see each other.
 * Despite not being together, Nyssa and Oliver are still married under the League of Assassins law however there's debates about this seeing as their marriage is listed as legally invalid. However, in, Nyssa still refers to Oliver as her husband; implying that there marriage is legal, despite the league being disbanded.
 * Due to Oliver and Nyssa often having similar and conflicting interests, they have both fought with and against each other on four separate occasions throughout the series; but she was never able to defeat Oliver.

Behind the scenes

 * In the DC comics, Nyssa Raatko is Ra's al Ghul's older daughter. She was alienated from her father and the League like on the show, and she plotted for decades to murder him and take control of the League, along with her younger sister Talia, whom she drove to insanity by killing and reviving her repeatedly with the Lazarus Pit.
 * In the promo for "Heir to the Demon", Nyssa is shown in full costume battling Roy Harper, however this scene did not make it into the final episode.
 * In, Nyssa explains to Thea "To the uninitiated he is Malcolm Merlyn". This is a reference to a line in Dark Knight Rises, where Bane (who is a League member) breaks the Batman.
