Fan Casting Mercy Graves in Superman: For A Better Tomorrow

Efficient, disciplined, and fiercely loyal, Mercy serves as Lex Luthor's chief of security and closest confidante. She rarely speaks unless necessary, preferring to observe every room before acting. While she believes in Lex's vision, her loyalty comes from respect rather than blind devotion, making her one of the few people capable of challenging him privately without fear. Physically capable and mentally sharp, she is as comfortable managing a corporate boardroom as she is neutralizing a threat before it reaches her employer.
