We can't stop screaming over this Supergirl sneak peek!

The iconic DC villain, Silver Banshee, is coming to CBS' hit superhero drama -- and only ET has the exclusive first photo!

As ETonline first reported,Chasing Life star Italia Ricci will make her National City debut as Siobhan Smythe, a second assistant hired by Cat Grant (Calista Flockhart) who immediately starts trying to one-up Kara Danvers (Melissa Benoist).

But Siobahn and Kara will also square off as their super alter-egos later this season when the new assistant eventually unveils her terrifying Silver Banshee badside.

In the comics, Silver Banshee has superhuman strength, speed, endurance, agility, an impressive ability to resist attacks and a gift for languages. She often uses her sonic-based abilities to weaken her victims and we truly feel sorry for whoever she is screaming at in our first look image above!

"We are so excited to be working with Italia. We've been a fan of her work for years and we cannot wait to see her take on this iconic comic book role,” executive producer Andrew Kreisberg said to ET an exclusive statement.

Ricci will make her Supergirl debut as Siobhan Smythe on Monday, Feb. 22 at 8 p.m. ET/PT on CBS.
