In one last act of spite, Brainiac's death automatically triggers his ship's self-destruct, which, according to Luthor, would eradicate the entire Earth and everything within a 15,000,000 mile radius. As the gravitational singularities powering Brainiac's ship threaten to explode, Superman rockets it into outer space, where it blows up. The Earth is saved, but Superman is thought to have been caught in an explosion and killed. In the epilogue at Lex Luthor's funeral a thousand years in the future, it is revealed that unbeknownst to the rest of the Earth, Superman survived the destruction of Brainiac's ship. He walks quietly away from the ceremony, planning to live among humans rather than ruling over them.
