The Arrowverse Superman origins in Superman & Lois bear similarities and differences to previous origins seen in Superman movies and TV series. Every new Superman film and TV series since 1978's Superman: The Movie rehashed the Man of Steel's familiar origin: Baby Kal-El rockets to Earth as the doomed planet Krypton explodes. Jonathan and Martha Kent raise him in Smallville as Clark Kent, and he eventually moves to Metropolis, where he fights evil as Superman. With Superman: Legacy as the next step for the Man of Steel on the big screen, fans will likely get another retelling of how Superman came to Earth.
