Flashpoint was a crossover event that eventually lead up to the rebooting of the entire DC Universe and the introduction of the controversial New 52 era in September, 2011.
DC Comics took the unprecedented decision to consolidate and relaunch all their comic lines, discontinuing some series while introducing new ones, resulting in 52 titles each all starting at #1. This consolidation included the incorporation of both the Wildstorm Productions and the reincorporation of certain Vertigo properties into the mainstream DC Universe. The event took its name from the company’s thematic associations with the number 52, which began with the publication of the weekly series 52, in which it was revealed that a Multiverse of 52 parallel realities existed within the DC Universe.
This story line features an alternate, more evil version of Diana.
