Star Sapphire is later recruited to the Injustice Gang's second incarnation led by Aresia to destroy the men of the world. When Aresia reveals the group's agenda, she is initially shocked, but ultimately joins enthusiastically.

During the mutiny led by Grodd, she sides with Luthor, and thus is among the survivors (since she and Sinestro use their powers to create a force field which protects their team) who arrive on Earth in time to warn of Darkseid's impending invasion. She joins the rest of the Secret Society and the Justice League in fighting off the forces of Apokolips, and is depicted fighting Parademons over the Great Wall of China beside Wonder Woman, Shining Knight and Vigilante.
