"Mr. Robot" star Stephanie Corneliussen has joined "Legends of Tomorrow" in the role of Valentina Vostok, who goes by Negative Woman in the comics.

According to TheWrap, the time displaced group of heroes and villains will meet Vostok during the height of the Cold War. Following her introduction, the Atom and Captain Cold will attempt to win her affections in order to discover if she is working with Vandal Savage (Casper Crump).

Negative Woman first appeared in Paul Kupperberg and Joe Staton's "Showcase" #94. A Lieutenant Colonel in the Soviet Air Force, she hijacked an experimental Russian Fighter Plane as she attempted to escape to the United States. When the plane malfunctioned and crashed in the same place where the Doom Patrol died, Vostok became joined with Negative Man's body, giving her the ability to fly, become intangible and generate minor explosions upon contact with positive energy. Over time, her body became permanently radioactive, forcing her to wear radiation-blocking bandages over all of her body. Vostok also briefly took over Checkmate from Amanda Waller, assuming the moniker the White Queen after losing her abilities.

Corneliussen's past credits include "The Exes" and "Royal Pains" in addition to her breakout role on "Mr. Robot."

Scheduled as part of The CW's midseason lineup, "Legends of Tomorrow" stars Caity Lotz as White Canary, Brandon Routh as the Atom, Wentworth Miller as Leonard Snart/Captain Cold, Dominic Purcell as Mick Rory/Heat Wave, Victor Garber as Professor Martin Stein (one-half of Firestorm), Renee as Hawkgirl and Arthur Darvill as time-traveler Rip Hunter. Stephen Amell and Grant Gustin will appear as Arrow and The Flash.
