Superboy (Kon-El)Created by Karl Kesel & Tom Grummett
In the wake of Superman’s death, Cadmus attempted to clone and replace him, but the clone was broken out of holding before he fully matured and he immediately made his presence known in Metropolis. Despite his youthful demeanor, he would snap at anyone that called him Superboy, and insisted on being referred to as Superman.
Once Superman returned, the clone did take the name Superboy, and was gifted the Krpytonian name “Kon-El” by Superman, who welcomed him into his family. Around this time he discovered that his powers, unlike Superman’s, derived from “tactile-telekinesis” meaning he could pretty much emulate the real deal, but he needed to be physically in contact with whatever he was effecting.
It was later discovered that Superboy was a clone made up from genetic samples from both Superman and Lex Luthor, which left him scared that he had as much capacity for evil as he did for good. He took the civilian name Conner Kent, and briefly shaved his head bald and turned evil due to conditioning by Luthor, but was stopped and welcomed back onto the Teen Titans by his understanding friends.
He proved himself a hero during Infinite Crisis when he put his body on the line to fight Superboy Prime and was ultimately killed. Kon-El returned to get revenge on Superboy Prime during The Legion of Three Worlds, and settled back into life in Smallville, reuniting with his friends in the Teen Titans, and briefly striving to learn what makes his genetic “father” Lex Luthor tick.
