Vostok will reportedly debut in one of the Legends of Tomorrow teams time jumps courtesy of Rip Hunter, appearing as a Cold War-era operative for the U.S.S.R. suspsected to be working on a secret weapon with Vandal Savage (played by Casper Crump). Wentworth Miller's Captain Cold and Brandon Routh's the Atom will reportedly vye for some romantic time with the Russian stalwart, with TVLine teasing a change of allegiance for Vostok.
In comic books, Vostok was introduced as a Soviet Air Force lieutenant who attempts to defect to the United States aboard a stolen experimental fighter.

She later became involved with Checkmate, eventually assuming Amanda Waller's position as White Queen.
