In "The New 52" (a 2011 reboot of the DC Comics universe), Doomsday made his official debut in September 2013 as a part of "Villains Month". In "Batman/Superman" #3.1 Doomsday attacked Krypton many years ago when Lara was a lieutenant in the elite military seminary. Colonel Zod faced him wearing an ancient armor of Krypton's warrior founders but their battle caused the death of thousands of Kryptonians. Zod apparently defeated Doomsday, sending him to the Phantom Zone. Years later, General Zod, now also imprisoned in the Phantom Zone, communicated with the child Kara Zor-El, telling her how he admired the creature because it destroyed everything, an attribute he sought for his people to be strong as years of complacency had made the Kryptonians weak. Zor-El narrated a prophecy in which the last knight of the House of El will travel to a distant planet after the destruction of Krypton. The last knight will be found by Doomsday later and will battle him to save his people, sacrificing his own life to do so.
