Nyssa Raatko (Russian: Нисса Раатко) is a supervillain in DC Comics. Nyssa Raatko was created by Greg Rucka and Klaus Janson for the Batman series of comic books. She is an enemy of Batman. She is the daughter of Ra's al Ghul and the older half-sister of Talia.^[1]

Nyssa made her first live-action appearance as a recurring character on the Arrowverse television series Arrow starting in the second season, played by Katrina Law. She also appeared in the final season of Gotham, portrayed by Jaime Murray.

In Batman: Death and the Maidens, it is revealed that Ra's al Ghul and a Russian-Jewish peasant woman had a love child named Nyssa born during his travels in Russia in the 18th century. Enamored by the romantic stories that her mother told her about Ra's as a child, Nyssa sets out to find Ra's and eventually locates him at his headquarters in North Africa.^[2]

Impressed by her beauty, warrior skills, and her determination and ability to locate him, he promotes her as his right hand associate and they go on adventures together. Ra's is so impressed with her abilities, he even allows Nyssa to use his Lazarus Pits. Like her sister Talia, Nyssa eventually becomes disenchanted with Ra's genocidal plans to "cleanse the Earth", and disassociates herself from her father sometime in the early 20th century. Ra's reluctantly approves this, believing that she will return to him and that she or her children will become his future heirs. To his disappointment, Nyssa refuses to give herself or her family to him, causing him to disown her permanently. He does however allow her to keep a Lazarus Pit for herself which helps her survive until the modern times.

During World War II, Nyssa and her family are quickly sent to a concentration camp, where Nyssa's entire family dies and she is rendered infertile by very Mengele-style experiments. At one point she begs Ra's for help, but he refuses her.

Broken by her horrifying experiences during this time, and enraged that Ra's has abandoned her and her family to die at the hands of the Nazis, Nyssa is finally motivated to act when her great-grandson – her last living descendant - is killed. She plots to kill Ra's by befriending, kidnapping, and brainwashing Talia and using her to kill Ra's. To this end, she captures Talia and, using a Lazarus Pit, kills and resurrects her in rapid succession. Rendered apathetic by her time in the camp, unable to feel anything, Nyssa then attempts to destroy all hope and optimism in the world by assassinating Superman with Kryptonite bullets she steals from the Batcave, hoping that, by uniting the world in one moment of tragedy, she will manage to rouse herself once more.

While Batman is successful in preventing the assassination of Superman, he is unable to stop Ra's from being killed by Nyssa.^[3] This in turn is part of a greater plan by Ra's to ensure that his daughters, both initially dissatisfied with his plans, will realize that he is right, and that they would come to accept their destinies as his heirs. Realizing and accepting this, both Nyssa and Talia become the heads of the League of Assassins.

The Lazarus pit can grant restorative properties that can heal injuries and even grant immortality. Nyssa owns one of the world's last Lazarus Pits, which has granted her longevity and the ability to heal her wounds; she survives The Holocaust thanks to its powers. She also found the ability to use the pit multiple times. She is also extremely wealthy, especially since she assumes control of Ra's' organization and joins forces with Talia. Like her father and half-sister, she knows every of Batman's secrets.

During "Infinite Crisis", Nyssa and her sister connive to use Talia's membership in Luthor's Secret Society of Super Villains to take over the planet. Nyssa tries to recruit Batgirl (as Cassandra Cain) to stand at her side as "The One Who Is All". She attempts to explain why she is working with the villains of the Society to Batgirl:

"Vast stockpiles of food rot, while people starve. Millions die from curable diseases, while drug companies rake in the billions. Our environment chokes on our waste, becoming so toxic that life fails. It's genocide by greed, apathy, and neglect. These are the real crimes. Something must change... The Society's plans are vast. They will succeed. I can't stop them. When the world gets a true taste of violent oppression, and their heroes lie dead and broken – apathy will die. That's when you'll lead my league to sanction key society members. Leaving Talia and I to lead the revolution. A new world will be born, one of peace and equality. Millions of lives will be saved".

Cassandra refuses, and, along with Mr. Freeze, escapes from Nyssa's grasp.

In "One Year Later", Nyssa is seen in Northern Africa, planning an unknown plot with two terrorists. As she gets into her car to leave, it explodes.^[4] In the following issue, Lady Shiva reports that Nyssa Raatko is dead where she was probably killed by the League of Assassins.^[5]

• Nyssa appears in series set in the Arrowverse, portrayed by Katrina Law:
  • First appearing in the second season of Arrow, this version previously rescued Sara Lance from Lian Yu and later became her lover. In the third season, Nyssa trains her sister Laurel Lance following the death of Sara Lance. In the third season finale, Nyssa works with Oliver Queen and his allies to defeat and kill Ra's. She then reappears in the fourth season to oppose Laurel's reckless scheme to resurrect Sara using the Lazarus Pit. She declines the leadership of the League and instead disbands it. In the fifth season, Oliver recruits Nyssa to join his team to oppose Adrian Chase and his team, which includes Nyssa's sister Talia. In the sixth season, Nyssa battles the Thanatos Guild. Nyssa is later seen in a flashforward in the seventh season, training Mia Smoak, Oliver and Felicity Smoak's secret daughter, throughout her childhood. In the series finale episode "Fadeout", Nyssa reconciles with Talia at Oliver's funeral.
  • Nyssa al Ghul appears in Legends of Tomorrow. The episode "Left Behind" reveals that Nyssa's first meeting with Sara Lance was caused by a Bootstrap paradox. She makes an appearance in "River in Time", where Sara says goodbye to her before she leaves on the Waverider.
  • Nyssa al Ghul appears in one of the tie-in comic books of the Crisis on Infinite Earths crossover event, along with Felicity Smoak, The Ray, and Wally West.^[6]
• Nyssa al Ghul appears in the fifth season of Gotham, portrayed by Jaime Murray. This version is initially under the Secretary of Homeland Security under the alias Theresa Walker and employs several henchmen, including Bane, Riddler, Leslie Thompkins, and Hugo Strange. After Jim Gordon and Bruce Wayne convince Riddler to turn over evidence on Nyssa, she is ousted from the government and forced to go on the run. After arriving in Gotham, she reveals to Bruce that she is Nyssa al Ghul, seeking vengeance for her father's death. Nyssa is ultimately defeated by Gordon and Barbara Kean, but escapes with Oswald Cobblepot's submarine, forcing Bruce to leave the city in pursuit of her.

• In Batman: Arkham Knight, Nyssa leads a faction vying for control of the League of Assassins against an ailing Ra's al Ghul. If Batman sides with Ra's, he is successfully rejuvenated and manages to escape Batman after killing Nyssa. However, if Batman sides with her, she manages to defeat Ra's but is convinced to spare him by Batman. She then leaves Gotham to hunt down the last of her father's loyalists in the League.
