Supergirl sure loves to pay homage to what has come before it. Before the show debuted this past fall, it was announced that Helen Slater, who played Kara in the 1984 Supergirl movie, would appear as the new Kara Zor-El's adoptive earth mom. Now, we have word that another Supergirl is joining the series in Season 1.

Things are about to get even more interesting in National City in 2016! The DC Comics characters Indigo and Master Jailer are set to debut on the super hero series Supergirl over the course of the next few months. CBS' hit was recently named Favorite New TV Drama at the 2016 People's Choice Awards.

Laura Vandervoort, who played Kara/Supergirl on the long-running hit drama series Smallville, has been tapped for the recurring role of Indigo. The character is described by producers as a living, strong-willed supercomputer. She was sentenced to Fort Rozz after turning against the people of Krypton. Now on Earth, Indigo will let nothing stand in her way.

In additional casting news, Jeff Branson (The Young and the Restless) has been cast in the recurring role of Master Jailer. As the forceful and unrelenting jail guard on Fort Rozz, Master Jailer showed no mercy. Now on Earth, he is hellbent on catching all of the Fort Rozz escapees and brutally bringing them to justice.

The announcement was made today during Warner Bros. Television's Supergirl session at the Television Critics Association Winter 2016 Press Tour on the Warner Bros. Studios lot. Supergirl is from Berlanti Productions in association with Warner Bros. Television. The series airs Mondays at 8/7c on CBS.
