Superboy-Prime is slowed down by a thick wall of pure willpower generated by the Green Lantern Corps. Breaking through, he battles 32 Green Lanterns, killing them. The two Supermen arrive and fly Superboy-Prime through Rao, the red sun of Krypton. The heat melts away Superboy-Prime's armor and severely weakens all three Kryptonians, who then crash on Mogo. Superboy-Prime beats Kal-L to death, but is then attacked by Kal-El. Superboy-Prime claims that he is better than Kal-El and that his Krypton was superior to Kal-El's. Kal-El responds, "It's not about where you were born. Or what powers you have. Or what you wear on your chest. It's about what you do... It's about action." Although nearly powerless, Kal-El knocks Superboy-Prime out before collapsing himself, but members of the Green Lantern Corps manage to save Kal-El.
