Who is Clark Kent

Young baby Kal-El was rocketed from his dying planet Krypton by his loving parents. Discovered by a Smallville, Kansas farmer and his wife, this child is raised as Clark Kent. Very early on, Clark displayed superhuman abilities such as superhuman strength. Drawing on his strong moral compass as a result of his simple Midwestern upbringing, upon reaching maturity Clark resolved to use his gifts for the benefit of mankind as Superman.

Clark Kent is employed as a mild-mannered reporter for the Daily Planet newspaper based out of Metropolis, a fictitious city existing in the DC Comics universe. There Clark works alongside reporter Lois Lane, who he secretly pines after.

Eventually Lois and Clark get married. Their relationship has been consummated by marriage on several occasions across various media, and this union is now firmly established within mainstream DC comics' continuity.
