DC Finest: Justice League of America: The Return #[nn]

As the Crisis rages on Earth-2, Commander Steel tricks the Infinitors to follow him to Earth-1 to capture the current JLA team, and his grandson (a member as Steel), believing they are renegades on that world, using Mekanique's powers to transport them to Earth-1. Once there, they confront the JLA'ers, and defeat them. But when the Infinitors realize they have been duped by the Commander, it's too late, as the Commander has plans for his grandson, whom they have already captured for him, while Mekanique attacks both the Infinitors and the JLA under the Commander's orders.
