Superman: The Man of Tomorrow Archives #3

Bizarro keeps the real Superman from revealing to Lois that she has been proposed to by Bizarro's duplicate, whom he calls New Bizarro, with a kryptonite meteorite, but Lois realizes New Bizarro is not the true Man of Steel. But New Bizarro doesn't give up easily, and the duplicates fight each other. Bizarro seeks out Superman's help and destroys the kryptonite, turning it into a dust cloud which destroys New Bizarro. Bizarro resumes courting Lois, until Lois creates a duplicate of herself so that Bizarro can have his own Bizarro-Lois.
