Synopsis
The Supermen drive Superboy Prime through a red sun, and as his powers begin to ebb, he uses the last of his super-strength to kill the older Superman. He is then subdued by the younger version, and the Green Lantern Corps imprison him on Oa in a special science-cell containing a mini red sun, but he vows he will escape, like he did the Speed Force before. In an epilogue, Alexander Luthor Jr. vows he will return to recreate the new multiverse in his image of a single ‘perfect’ universe, but is killed by the Joker.
