Superman Red/Superman Blue: Difference between revisions

In the story, Superman is compelled to finish a list of unaccomplished goals, including the enlargement of the Bottle City of [[Kandor (comics)|Kandor]] and eliminating crime and evil from Earth. In order to accomplish these goals, Superman invents a machine, powered by various types of [[Kryptonite]], that will increase his intelligence. The machine works, increasing Superman's intelligence a hundredfold, but with the unexpected side effect of splitting Superman into twin beings, one outfitted in an all-red costume (aside from thea yellow belt and the yellow areas of the chest emblem) and another in an all-blue costume (excepting a yellow belt and the chest emblem which is the normal red and yellow). The twins name themselves Superman-Red and Superman-Blue.<ref>{{cite book |last1=Greenberger |first1=Robert |last2=Pasko |first2=Martin |title=The Essential Superman Encyclopedia |date=2010 |publisher=Del Rey |isbn=978-0-345-50108-0 |pages=422–423}}</ref>
