At the Fortress, Superman attempts to lay one last trap to stop Zod but fails. As Zod holds Superman in submission, Luthor reveals the ability of the Fortress to revert Superman into a human, a punishment that Zod sets forth. When Superman steps into the transformation chamber, the rest of the Fortress is bathed in red light. The three villains realize too late that Superman, knowing of Luthor's treachery, altered the transformation process to expose everyone outside the chamber to the red light, thus canceling Zod, Ursa, and Non's Kryptonian powers. With Lois' help, Superman is able to send the criminals into the bottomless depths of the Fortress. (In deleted scenes, it is revealed that human, presumably Canadian, authorities arrest the now powerless Kryptonians.)
