Nyssa Raatko was created by Greg Rucka and Klaus Janson for the Batman series of comic books.

[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.

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.

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.

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.

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.

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.

She attempts to explain why she is working with the villains of the Society to Batgirl: "Vast stockpiles of food rot, while people starve.

When the world gets a true taste of violent oppression, and their heroes lie dead and broken – apathy will die.
