Natalie Gumede has been cast as Mercy Graves for the second season of DC Universe's Titans, according to Deadline.
"Mercy Graves is the ruthless, cunning, right hand and bodyguard to the notorious Lex Luthor – serving her boss with unquestioned loyalty," reads a description from Titans' producers. "Her connection to the Luthors runs deep, as Mercy has been a friend of the family and in Lex’s life since they were young."
Lex Luthor has not yet been cast in Titans, but his involvement in the show has been mentioned by Geoff Johns back in 2018, tying into Superboy's comic book origin having the DNA of both Superman and Luthor.
Gumede is best known for her role as Bella in ITV's recent Jekyll & Hyde, and has had smaller roles on other British TV shows including 2014's Doctor Who Christmas Special as Ashley.
Filming on the second season of Titans is underway now, and DC announced that the season will premiere later this year on the DC Universe streaming service.
