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.
Wonder Woman only appears on the cover of this issue and is not featured in the story itself.
Waking up suddenly at his desk, Barry Allen has only a few seconds to puzzle out the fact that something in his work environment has changed before he hears that a Rogue named Miss Alchemy is engaging in a felony. Barry starts running to get there… only to fall down a nearby flight of stairs. This alone is a puzzle to him, but then he is greeted by an even bigger shock – Nora Allen, still alive in the present day and coming to visit him. He is also briefly visited by Professor Zoom, who has retained his powers despite Barry losing his.
Elsewhere, the Cyborg has called an assembly of the world’s greatest heroes to try dealing with the situation in Europe, where Wonder Woman’s Amazons are set to go to war with Atlantis’ newly-acquired continental territories. The assembled heroes drag their heels but Cyborg gets a plurality.
Back in Central City, Barry begins quizzing his mother about how much the world has changed. It seems that, whatever has happened to the world, Nora Allen has no notion of Superman or the Flash, but she has heard of the Batman of Gotham City.
Meanwhile, in Gotham, a shadowy figure chases a colorful criminal across the neon-strewn rooftops. The Batman has chased the criminal known as Yo-Yo because he wants the location of the Joker.
From his superhero career, Barry Allen knows the location of the Batcave, but he is shocked by the changes to the décor — in place of trophies and evidence, there is only… bats. In the location once occupied by Jason Todd’s Robin costume is a stand with a gun. At this point, Batman arrives and begins beating him up. Barry tries to talk him down by calling him Bruce, but this does not have the desired effect. Catching sight of a Wayne family portrait, Barry arrives, by a horrible process of elimination, at a new conclusion — Thomas Wayne is the Batman, and the world has changed almost beyond recognition.
