Luckily, she is approached by Donna Troy, who joins the team alongside her friends Cyborg, Dick Grayson, and Starfire. With the costume given to her by Hardware destroyed, Kimiyo designs a new one, and then travels to Metropolis to recruit Mon-El and the Guardian. Kimiyo briefly appears during the War of the Supermen, where she and the rest of the JLA attempt to repel General Zod's invasion forces. After just three issues together, the new JLA team loses most of its members, with Kimiyo temporarily leaving the team to be with her children.
