A 2005-2006 DC crossover written by Geoff Johns with art by Phil Jimenez, George Pérez, Ivan Reis, and Jerry Ordway. The seven-issue series is a sequel to 1985's Crisis on Infinite Earths.
The plot centers on characters from the pre-Crisis multiverse returning, including Superman of Earth-2, Alexander Luthor Jr. of Earth-3, and Superboy-Prime. Disillusioned with the current DC Universe, they attempt to create a new world by merging realities. The event restored the multiverse concept and led directly into the 52 weekly series.
