“Arrow” is finally introducing another daughter of Ra’s al Ghul.

Lexa Doig (“V,” “Stargate SG-1,” “Continuum”) has been cast in a recurring role as Talia al Ghul, Variety has learned. Talia is the daughter of Ra’s — who was the main villain in “Arrow’s” third season, played by Matt Nable — and the half-sister of Nyssa al Ghul, who’s played by Katrina Law.

Talia, like Nyssa, is an elite warrior, excelling in multiple different forms of combat. Unlike her sister though, she refuses to pick sides and instead creates her own. Doig’s first appearance as Talia will be in the tenth episode of Season 5.

Talia was confirmed to exist in the “Arrowverse” in an episode of “DC’s Legends of Tomorrow,” where the team met a much younger version of her in the 1960s. Presumably, the Lazarus Pit is what has kept her young in the time between then and when she shows up on “Arrow.”

This won’t be the first time that Ra’s al Ghul’s most famous daughter has been adapted for live-action. Marion Cotillard played the character in Christopher Nolan’s final Batman film, “The Dark Knight Rises.” In the comics, she is also the mother of Bruce Wayne/Batman’s son Damien.

Doig is repped by Jamie Levitt, Lauren Levitt & Associates Inc.

“Arrow” airs on the CW on Wednesday’s at 8 p.m.
