CBS's Supergirl has just added another Girl of Steel to its cast. Laura Vandervoort, who played Kara/Supergirl on Smallville, has been added to the cast in the recurring role of Indigo.
Supergirl's version of Indigo, who in comic books had a connection to Brainiac, is described as a "living, strong-willed supercomputer that was sentenced to Fort Rozz after turning against the people of Krypton."
In addition to Vandervoort, Jeff Branson of The Young and the Restless fame has been cast as the Master Jailer, a former jailer at Fort Rozz who has come to Earth hellbent on recapturing the escaped convicts.
Supergirl returns on Monday, January 18 on CBS.
