The CW's Arrowverse launched a franchise predominantly out of lesser-known characters from DC Comics, with the likes of Batman and Wonder Woman being left out. Ra's al Ghul shows up on "Arrow," but Nyssa gets a fair amount of attention on the series. She's a recent addition to DC Comics, created in 2003. Writer Greg Rucka and artist Klaus Janson brought the character, known as Nyssa Raatko, to life in the story arc "Batman: Death and the Maidens." She's a half-sister to Talia, as Ra's conceived her with a peasant woman he met in the 1700s.
Much like on "Arrow," Nyssa doesn't have a good relationship with Ra's in this storyline; he seeks her aid in constructing more Lazarus Pits, but she refuses to go along. By the end of the series, Nyssa succeeds in killing Ra's and rejoins the League of Assassins with Talia. Nyssa continues popping up in the comics, even appearing in the "Infinite Crisis" event. However, she doesn't last long. Nyssa dies in 2006's "Robin (Volume 2)" #148, written by Adam Beechen with art from Karl Kerschl and Wayne Faucher. The character perishes after her car explodes, but this Daughter of the Demon has lived on in other media.
Nyssa returned to live-action on "Gotham," this time portrayed by Jaime Murray. Jennifer Hale voiced the character in "Batman: Arkham Knight." Nyssa may not be Batman's baby mama, but she's making a name for herself.
