In the "Infinite Crisis" storyline, Kal-L himself returns to the post-"Crisis" DC Universe after breaking down the walls of the paradise dimension in which he, Lois Lane Kent (of Earth-Two), Alexander Luthor, Jr. (of Earth-Three), and Superboy-Prime (of Earth-Prime) had been living since the end of "Crisis on Infinite Earths". Appalled by the rapidly deteriorating state of affairs on the contemporary Earth, their goal is to replace the post-"Crisis" Earth with a recreated Earth-Two. Kal-L's first order of business is to track down Power Girl and explain the events of the original Crisis to her. Kal-L also reiterates her pre-"Crisis" history as his cousin. A touch from the ailing Lois of Earth-Two inexplicably restores Power Girl's memories of pre-"Crisis" Earth-Two.
