Barry Allen Black Flash DCAU

In Flash Rebirth, WHen Barry is readapting to life, the speedster villain Savitar escapes the Speed Force through Flash and he gives chase. When Flash manages to put his hand on Savitar's shoulder, the villain screams in agony and crumbles into dust, not before telling Flash, "...You were the beginning, Allen...and you're the end." At that moment, Wally West, West's children Iris and Jai, Liberty Belle, Jay Garrick, and Kid Flash all experience painful convulsions and are engulfed in lightning. Shocked at what happened to Savitar, Flash asks himself, "What the hell did I just do?"

Barry's conflict with the speed cult culminates with the death of their new leader who was attempting to avenge Savitar's death. It causes pain once again to all the speedsters, though Wally West manages to catch a glimpse of Allen directly afterwards, and sees him as the new Black Flash. When he realizes that his presence could damage or kill other innocents, Barry flees back into the Speed Force, where he encounters old friends Johnny Quick and Max Mercury. Max attempts to tell Allen that his becoming the Black Flash is not his fault, and when Max and Barry are pulled into another pocket of the Speed Force, the real culprit reveals himself: Professor Zoom.
