Rhona Mitra & Robert Baker Cast As Mercy & Otis Graves On 'Supergirl' Series

A new set of villains are moving into National City with Rhona Mitra being cast for a recurring role on the CW’s series Supergirl as 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.

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. The character of Marcy Graves first appeared in Superman: The Animated Series.

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.
