As the chaos of the old multiverse being restored continues, Alex decides he wants to create the ‘perfect’ Earth, one without a Superman, and uses his abilities to mix and match varying realities, but his efforts to create a perfect reality all end in failure, merging various earths in the process, and as failures, destroying them as well. Across countless parallel worlds, scores of super-heroes deal with the cosmic upheaval of the multiple replicating Earths.
Alex even tries to merge Earth-Two and Earth-Three together, which makes Donna Troy realise that he is going to kill Superman and Wonder Woman. To prevent this, her team of heroes at the centre of the universe fire at Luthor’s hands, causing him to lose his right index finger and to distract him long enough to save Wonder Woman and the two Supermen.
The heroes finally stop him, but at a cost, as Superboy [Conner Kent] destroys the tower that was allowing for the earths to appear while battling vs. Superboy-Prime, freeing the captured heroes and villains to join in the fight. But sacrifices his own life in the process.
