Lois Lane is a top reporter for the Daily Planet. She is the daughter of Sam Lane, the estranged older sister of Lucy Lane, the wife of Clark Kent, and mother of Jonathan and Jordan Kent.

A strong and assertive investigative reporter who would rush headlong into dangerous situations to uncover the truth, Lois was in love with both Superman and Clark for a very long time, unaware at the time, that the two were one-and-the same. Eventually, Clark revealed his alter-ego to her and they were married, starting their own family.
