Flashpoint

Still haunted by the death of his mother, Barry goes back in time to save his mother from ever being murdered by the Reverse Flash. In doing so, The Flash causes a temporal ripple that creates a fractured reality where the Justice league has never formed, Superman does not exist and a war rages between Wonder Woman and Aquaman. Flash must team with Batman, Cyborg, and other heroes to restore the timeline and come to terms with the thing that haunts him the most.
