Our first look at Italia Ricci as the 'Silver Banshee' has arrived and she looks scary good. Come catch a look of the terrifying villainess and also check out three new stills from Monday's episode.

On Monday night's episode of Supergirl, Italia Ricci (Chasing Life) will make her debut as Siobhan Smythe, a second assistant hired by Cat Grant who will prove to be a thorn in Kara's side almost immediately. In addition to her causing trouble for Kara on the homefront, she'll also stir up more than a little trouble for Kara on the superhero-front as well when she unveils her 'Silver Banshee' alter-ego and wreaks havoc on National City.



It's unclear as to when we'll see her make the transformation, but if recent set photos are anything to go by, it'll most likely occur around the same time as the crossover episode with The Flash, which is set to air on March 28.



ET Online has released our first official look at Ricci as the 'Silver Banshee.' Check her out below:
