According to TVLine, the CW has cast actress Stephanie Corneliussen (Mr. Robot) to play Valentina Vostok in multiple episodes in the upcoming ‘DC’s Legends of Tomorrow.’

Her character is described as:

A gifted and beautiful Soviet physicist who will stop at nothing to defend her precious “Motherland.” When the Legends encounter her at the height of the Cold War, they suspect her of working with Vandal Savage (Casper Crump) on a secret weapon. Ray/The Atom (Brandon Routh) and Leonard/Captain Cold (Wentworth Miller) must vie for Valentina’s affection in an attempt to thaw her cold heart, and find out where her allegiance truly lies -— before she completes her project and potentially turns the tide of the Cold War.

Official Synopsis:

When heroes alone are not enough… the world needs legends. Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat – one in which not only is the planet at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known?
