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 her father and eventually locates him at his headquarters in North Africa. Impressed by her beauty, warrior skills, and 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.
The Second World War During World War II, Nyssa and her family are quickly sent to a
concentration camp, where Nyssa's family is killed. Nyssa herself is experimented on and rendered infertile. At one point she begs Ra's for help, but he declines to offer any.
Death and the Maidens 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-grandsonher 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 attempts to destroy all hope and optimism in the world by assassinating
Superman with
kryptonite bullets, 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. 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.
Lazarus Pit 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.
"Infinite Crisis" 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: 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. In the following issue,
Lady Shiva reports that Nyssa Raatko is dead, probably killed by the
League of Assassins.
Post-Rebirth Nyssa Raatko is reintroduced in the 2025 series
Batgirl. In the series
Cheetah and Cheshire Rob the Justice League, it is revealed that Nyssa had a daughter named Alya Raatko, alias
Featherweight, who is
transgender. ==In other media==
