Professor Zoom
Barry's conflict with the speed cult culminates in 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. When Max and Barry are pulled into another pocket of the Speed Force, the real culprit reveals himself: Professor Zoom.
