A sole survivor of a now destroyed planet, Krypton, Kal-El was rocketed to Earth to be saved by his biological parents. When he crash landed on Earth, Kal (Who was still an infant) was adopted by Jonathan and Martha Kent. He was given the name Clark Kent. Upon growing up, Clark was lost in discovering who he was. When he reached adulthood, he eventually became Superman, the most powerful hero. He eventually met Batman and became close friends with him, and would eventually help form the Justice League.
