First mentioned in "Green Lantern" #20 as the first female Green Lantern of Earth, Jessica Cruz is a young Latin American woman who was forced to become the unwilling host to the evil Ring of Volthoom after "Power Ring" dies in his alternate Earth universe. Though she is not technically "Power Ring", as she is not a member of the Crime Syndicate and has no association with the organization, for namesake purposes she is dubbed "Power Ring" while the ring uses her as a host. She is helped by the Justice League and Simon Baz, who help her understand her cursed powers. In the Darkseid War, she becomes trapped inside the Ring of Volthoom, as Volthoom himself takes over Jessica's body. She then battles the previous wearers of the ring with the help of Cyborg, and forces her body in front of the Black Racer (who, at the time, was controlling the Flash) and kills Volthoom. After the battle, whilst the League mourns her motionless body, a Green Lantern ring appears and Jessica is made the sixth Green Lantern of Earth, to everyone's surprise.
