In "All-Star Superman", the 12-issue comic book series by Grant Morrison and Frank Quitely, Lois becomes a Kryptonian Superwoman for 24 hours. In the story, Superman (who believed he was dying) revealed his secret identity to her and takes Lois to his Fortress of Solitude to spend her birthday. While at his Arctic sanctuary, he presents Lois with her birthday present, a formula called "Exo-Genes" created by Superman from his own DNA, that allows Lois to have his powers for twenty-four hours. With her new Kryptonian powers and new Superwoman costume (made by Superman), the two spend the whole day together on different adventures and shared a kiss on the moon. At the end of the story, Superman proclaims his love for Lois, before he flies off into the sun to repair it. Lois later appeared as Superwoman in the animated All-Star Superman film, voiced by Christina Hendricks.
