Zena was a crewmember onboard the prison station which held Davros.
She was one of the few survivors of the Dalek raid on the station. Along with Styles and another crewmember, she was shot and killed by a Dalek Trooper while attempting to destroy the station. (TV: Resurrection of the Daleks)
Behind the scenes
In the credits, this character, like the other crewmember, is simply listed as "Crewmember", though her name is spoken by Styles.
