Mr. Robot star Stephanie Corneliussen will play Valentina Vostok (a.k.a. Negative Woman/White Queen) on DC's Legends of Tomorrow, TVLine reports.

Corneliussen, who plays Joanna Wellick on Mr. Robot, will appear in "multiple episodes" of the upcoming Flash/Arrow spin-off, according to TVLine.

Her Legends of Tomorrow character is a Soviet physicist whom the Legends suspect is working with Vandal Savage (Casper Crump) on a secret weapon during the height of the Cold War. It also looks like she'll be part of a love triangle with The Atom (Brandon Routh) and Captain Cold (Wentworth Miller).

In the comics, Valentina is a lieutenant colonel in the Soviet Air Force who stole a Russian fighter plane in order to escape to America, and transforms into Negative Woman when her plane crashes. When she eventually arrives in the United States, she becomes a member of Doom Patrol and eventually works for the American government.

DC's Legends of Tomorrow will premiere later this season on The CW. Do you think Corneliussen is a good addition to the show?
