- "The world changed when Superman flew across the sky. Then it changed again when he didn't."
- —Amanda Waller on Superman's legacy
The Death of Superman was a major turning point in the history of the planet Earth, with the universe made aware and the threat of Steppenwolf due to invade the planet after his invitation by Alexander Luthor, Jr..
After Alexander Luthor, Jr. created Doomsday from the deceased body of Dru-Zod, the unstoppable monster was confronted by Superman in a battle and was shortly joined afterwards by Batman and later Diana.
The battle ranged from Metropolis to Gotham City via a short lived battle on Stryker's Island. As Lois Lane tried to retrieve the Kryptonite Spear from down a flooded staircase, Superman saved her and then proceeded to use the Spear himself. He flew directly at Doomsday and impaled the creature in the chest. Doomsday returned the favor with his Bone spike that replaced a hand chopped off by Diana, and the two Kryptonians died from their wounds.
Batman was first to Superman's body and proceeded to wrap it in his cape and lowered it down to Diana, who lay Superman on the floor as Lois Lane approached and held Superman's body in her arms.
Lex Luthor made contact with Steppenwolf in the Scout Ship who he told of Superman's demise. Steppenwolf then told Lex of his plan to find 3 Mother Boxes before Metropolis Police Department S.W.A.T. officers arrived and interrupted the communion and arrested Lex.
The whole world mourned Superman's heroic sacrifice. His body was taken back to Smallville in secret where he would be buried as Clark Kent in a private ceremony. Meanwhile in Metropolis, the whole city virtually shut down and a huge funeral procession was held in Heroes Park where the old Superman Statue was replaced with a Superman Memorial and an empty Black Casket buried beneath a huge Superman emblem.
