After getting her big break in Christopher Nolan's The Dark Knight Rises (2012), playing a young Talia al Ghul, Joey King is headed back to the DC Universe, but this time, she'll be playing Magenta — a meta-human with the ability to control metal — in the third season of The CW's The Flash.

Today, King posted a photo of her new, villainous appearance. Since it is a close-up shot, we can only see the color transformation her hair has gone through, though a set photo from earlier this month — which can be viewed below as well — may reveal her costume.

King's other acting credits include roles in Oz the Great and Powerful, The Conjuring, White House Down, and Independence Day: Resurgence, as well as a recurring role in the first season of FX's Fargo.

Blinded by anger, Barry Allen (Grant Gustin) unwittingly plays into Zoom’s game and uncovers the evil speedster’s true goal: to destroy all Earths in the multiverse. In the race of his life, Barry ultimately gets the upper hand against Zoom and defeats his nemesis. But unable to celebrate victory, Barry makes a world-shaking decision and speeds back in time to the night his mother died to stop Reverse Flash from killing her, irrevocably changing his past and redetermining his future.

The cast also features Candice Patton as Iris West, Jesse L. Martin as Detective Joe West, Danielle Panabaker as Caitlin Snow, Carlos Valdes as Cisco Ramon, and Tom Cavanaugh as Dr. Harrison Wells.

Based on the characters from DC, THE FLASH is from by Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television, with executive producers Greg Berlanti (“Arrow,” “Supergirl”), Andrew Kreisberg (“Arrow,” “The Flash”), Sarah Schechter (“Arrow,” “DC’s Legends of Tomorrow”) and Aaron and Todd Helbing (“Black Sails”).

The third season of The Flash will debut on Tuesday, October 4th at 8 p.m. (EST).
