Superman (kal'el) is the flagship hero in the
DCu. He is the unofficial leader of the
JLA. He was born on the planet Kyrpton in its dying moments but was rescued by his parents and sent to earth where he was adopted and raised by Johnathan and Martha Kent. He took the name Clark Kent. In the DCu Superman is among the strongest, because the radiation of the yellow sun of the earth reacted with that of the red sun of
krypton granting him invunirability to everything except Kryptonite, a material found only on
Krypton. There is only one hero who can defeat Superman, in case he ever goes mad, and that is Batman, who keeps ample suplies of Krypontie in
the Batcave.
