'Forgotten'
A battalion of Green Lanterns passed through a time-portal to Earth and were shocked to find themselves outflanked by their enemies, the Zamarons and Lex Luthor's Legion. Jordan Cross, a former Justice League leader who had joined the Green Lantern Corps years earlier, hoped that he would find the league there, but they were nowhere to be found.

The Justice League eventually joined the Green Lanterns, and defeated the Legion and the Zamarons, all except for Lex Luthor. Lex Luthor, with his powered exoskeleton, had gone mad. He shot powerful lasers randomly in all directions. Green Lanterns worked frantically to defend the Solar System.
Clark Kent (AKA Superman) offered to get help from the planet below.

Clark flew toward the United States to a small city on the Eastern Seaboard called Hackensack. There, in a decrepit apartment building, he would find the one he needed, the only person who could defeat Lex Luthor.

It was Eve Teschmacher, whom
Clark had met years before when she went by the name 'Amy Palmer'. Clark entered through a window. Amy was watching Lex on the news, and was crying. "Clark!", she cried to him in disbelief.

Clark looked into the eyes of Amy Palmer and saw the girl whom he had first met as a teenager. It seemed so odd what he had to ask of her, but he knew it had to be asked. "I need your help one last time, Amy", he told her. "Together we can stop him. Lex has to be stopped."
