Swan will be portraying Medusa, the Queen of the Inhumans and wife of Black Bolt (Anson Mount). The actress previously appeared on Graceland played Zatanna on Smallville. Marvel TV head and executive producer Jeph Loeb said that “Serinda empowers Medusa’s regal glory and still maintains a relatability that synced perfectly with the character. She is nothing short of wonderful.” Showrunner Scott Buck also added that “Serinda Swan brings a regal elegance, as well as a sense of great inner strength and fierce determination, to the role of Medusa. I couldn’t be happier to have her as our Queen of Attilan.”
