Rhona Mitra (“Underworld Awakening”) has joined the cast of the CW’s “Supergirl”, playing the villainous Mercy Graves, Lex Luthor’s longtime bodyguard. Also cast in a recurring role on the DC series is Robert Baker, who will play Mercy’s brother, Otis Graves.
Per Deadline, “Based on the iconic DC character, Mercy Graves (Mitra) is an ex-CADMUS agent who has always believed in human exceptionalism. But with both Lex and Lillian in prison, Mercy is stepping out of the Luthor shadow and running her own show. With her biting wit and lethal brawn, Mercy steadily becomes a key figure in National City’s growing “human-first” movement.
Baker’s Otis Graves is Mercy’s defacto right hand man. What he lacks in brains, he makes up for with his savant-like abilities to assassinate aliens. Otis is a character from the Superman movies with Christopher Reeve and has not been featured in comic books.”
