SUPERMAN: Sent to Earth from the dying planet of Krypton as a baby, Kal-El was found by farmers Martha and Jonathan Kent and raised as their son, Clark. As Clark grew up, the radiation from Earths yellow sun gave him extraordinary powers, which he kept hidden. Now fully grown, he uses his powers to protect his adopted world as Superman.

DOOMSDAY: Doomsday is an alien creature of overwhelming force and savage blood lust, whose appearance invokes terror. When he first arrived on Earth, his rampage of mindless destruction devastated Metropolis. The carnage ended only after Superman died putting the mindless beast down."
