Krys Marshall has landed a recurring role in Season 3 of CW’s “Supergirl.”

According to TVLine, Marshall will play the mysterious character of Julia Freeman, a 20-something musician residing near National City who holds clues to Reign’s (Odette Annable) true identity.

Shortly after her casting was announced, Marshall took to Twitter to reveal how excited she is to be part of the superhero series.

Marshall’s Julia is just one of the new characters that viewers will meet when “Supergirl” returns from its hiatus next year.

In the trailer for the episode, Brainiac 5 appears to team up with his fellow Legion of Super-Heroes members Mon-El (Chris Wood) and Saturn Girl (Amy Jackson) to protect National City from Reign while Supergirl (Melissq Benoist) recovers from the injuries she sustained during her initial encounter with the Worldkiller in Season 3, episode 9.

Three-time Emmy winner Laurie Metcalf will also show up on “Supergirl” next year. As revealed last month, Metcalf will appear as Winn’s (Jeremy Jordan) estranged mom in Season 3, episode 15. Metcalf, is best known for playing the role of Jackie Harris on NBC’s “Roseanne” from 1988 to 1997, told Vanity Fair last month that she initially showed interest in the part “so her youngest child can meet her idol Melissa Benoist.”
