Deciding that it was time for him to become a public figure, Clark and Jonathan designed a symbol for him to wear while Martha created a costume.
Martha Kent modeled a costume after traditional Kryptonian garb out of his baby blanket, and Clark began operating in his youth as Superboy.
Repeated attempts to murder Superman eventually led to Lex Corp developing an imperfect clone of the Kryptonian named Bizarro.
Jimmy began using a signal watch of his own design to call Superman whenever he was in peril.
Raised with high moral ideals, he uses his incredible strength, speed, flight and various other superpowers to fight evil and protect the innocent.
In his civilian identity he is Clark Kent, a mild-mannered reporter working for the Daily Planet in Metropolis.
