Tie-in in the context of "Flashpoint (comics)"

"Flashpoint" is a 2011 comic book crossover story arc published by DC Comics. Consisting of an eponymous core limited series and a number of tie-in titles, the storyline premiered in May 2011. The core miniseries was written by Geoff Johns and pencilled by Andy Kubert. The series radically changes the status quo for the DC Universe, leading into the publisher's 2011 relaunch, The New 52.

Flashpoint details an altered DC Universe in which only Barry Allen seems to be aware of significant differences between the regular timeline and the altered one, including Cyborg's place as the world's quintessential hero, much like Superman is in the main timeline, with Superman himself being held captive as a lab-rat by the United States government within an underground facility in Metropolis. In addition, Thomas Wayne is Batman, and a war between Wonder Woman and Aquaman has decimated western Europe.
