CBS’ “Supergirl” is readying another DC Comics character for battle.

The drama has cast “Chasing Life” alum Italia Ricci in the recurring role of Siobhan Smythe. The latest hire by Calista Flockhart’s media mogul Cat Grant, the character is first introduced as a workplace adversary for Melissa Benoist’s heroine. But she later becomes a much more deadly foe when she takes on the mantle of DC Comics villain Silver Banshee.

Ricci will first appear in the 14th episode of the freshman drama, which received its full-season order earlier this week.

“We are so excited to be working with Italia,” said “Supergirl” exec producer Andrew Kreisberg. “We’ve been a fan of her work for years and we cannot wait to see her take on this iconic comic book role.”

The casting is also proving to be a family affair among this and the other Warner Bros.-produced crop of superhero shows. Ricci is engaged to Robbie Amell, who appeared on CW’s “The Flash.” (Amell had also guested on her recently departed ABC Family series).

Ricci is repped by ICM, Protégé Entertainment, Coast to Coast and Felker, Toczek, Suddleson LLP.
