Superman-X, kryptonian name Kell-El, was born in the 41st century and is a clone of the 21st century hero Superman. Created by the digitized gestalt inventor K3NT using DNA from the first Superman, Superman-X was genetically conceived to possess all of Superman's strengths, but none of his weaknesses. Unlike the original Superman, Superman-X was not vulnerable to the effects of Kryptonite. In fact, his body actually produced Kryptonite radiation, which he could channel and project in the form of concentrated blasts of energy from his hands. As a young man, Superman-X fought to save the galaxy from the tyranny of a conqueror known as Imperiex. He learned from K3NT that he was created expressly for the purpose of fighting Imperiex. Imperiex's army proved too strong for Superman however, and he was forced to look to the past to find a way to save his future. He traveled backwards in time one-thousand years to the 31st century where he met the Legion of Super-Heroes.
I think this is one of my favorite legionnaires of all times. The design team on the TV show did a great job for this character. I'm glad I was able to finish it before my first WonderCon.
