Supergirl arrives just in time to save Billy McCoy, so the creature who looks like Superman turns its attention to her. In the midst of their fight, Lois' shouts rouse the real Superman, who is floating in space. Realizing he is psychically linked to the creature, Superman uncovers that it is a creation of nanites from Jazuur -- a planet once visited by the Collector of Worlds -- who are trying to create the kind of order they were programmed to create on Jazuur. Superman returns to Earth and takes care of the nanites, throwing their remains into the sun.
