[1] In live-action, Valentina Vostok made her debut in the first season of the CW Arrowverse series Legends of Tomorrow, played by Stephanie Corneliussen.

Valentina Vostok is a lieutenant colonel in the Soviet Air Force who steals an experimental Russian fighter plane to defect to the United States.

After crashing at the site of the original Doom Patrol's death, Vostok fuses with a negative spirit and gains the ability to transform into one.

As the Negative Woman, Valentina possessed a radioactive "soul-self", and was capable of flight, intangibility, and could generate minor explosions upon contact with positive energy.
