After a near-fatal encounter with kryptonite, Superman learns he fathered a son, Jason, with Lois Lane—now engaged to Richard White. A crystalline Kryptonian woman, Kem-L, arrives claiming to be the last survivor of his homeworld, but her true goal is to rebuild Krypton by terraforming Earth and purging humanity. As Kem-L unleashes catastrophic meteor showers and black kryptonite smoke across the globe, Superman must fight his equal while Lex Luthor manipulates the U.S. government into embracing his anti-Superman agenda. The Man of Steel ultimately sacrifices himself by dragging Kem-L into the Sun, saving humanity and securing a future for his son.
