Barry Allen wakes up powerless and living in a different, much darker world than the one he knows. Heroes are villains, villains are heroes, and worst of all, Themyscira and Atlantis are waging a brutal war with each other that has caused millions of deaths and is likely to bring about the end of the world. The one bright spot for Barry is that his mother is still alive, but even his joy at seeing her doesn’t stop him from wanting to return to the world he knows. Without spoiling too many of the details, Barry eventually learns that he created this world when he went back in time and prevented his mother’s murder, albeit with a little prodding from the Reverse-Flash.
