Superboy (Kal-El)
The name of Superman as a boy, Superboy has adventures that occur in the relative past to those of Superman and take place predominantly in his hometown of Smallville. Superboy is from the destroyed planet Krypton, where he was born under the name Kal-El, and lives on Earth under the secret identity of mild-mannered student Clark Kent. Debuting in 1944, the character was in continuous publication for 40 years, developing a supporting cast and mythos of his own, before DC Comics removed him from Superman's fictional history. In 2009, however, DC Comics partially restored Clark's teenage career as Superboy. Superboy or elements from his story have been adapted to other media, particularly television.
