In the episode "Brave New Metropolis" Lois Lane travels to an alternate reality of Metropolis. Mercy Graves is the commander of Lex Luthor's law-enforcement group. She and her soldiers raid the hideout of the revolutionaries led by Jimmy Olsen where they arrest the revolutionaries, confiscate the stolen Kryptonite, send the adults to prison, and send any children of the revolutionaries to the LexCorp Orphanage. When she hears Jimmy call out to Lois, Mercy had her brought before Lex Luthor after the DNA tests prove that she is Lois Lane. Lex Luthor decided that in order to keep Superman at bay, it would be best to dispose of Lois. He sent Mercy to kill her in the city. On their way, they came across Angela Chen, who managed to distract the commander. Lois stole Mercy's gun and before she could react, Angela had bitten her leg. Lois made her getaway. Lois and the alternate Superman met where he learned what Lex Luthor has been doing behind his back. In the LexCorp building, Mercy was present when Lois and Superman confronted Luthor. Mercy fought Lois, but ultimately lost when Lois planted a jaw-breaking left hook. Rebels stormed into the room and poured onto the hated Mercy while Superman pursued Lex Luthor.
