After the Flashpoint event, in which Barry Allen's trip to the past altered the timeline, Wally was trapped in the Speed Force. There, he sensed a presence, who he realized was a being from outside the universe. This being was responsible for preventing the timeline from re-forming correctly after the Flashpoint, by removing a decade from history. Wally, observing the new universe from the speed force, repeatedly tried to break through to warn that world's heroes of the impending threat. None of those heroes remembered him, however, as in their timeline they'd never met him. Just before he fully faded away to become one with the Speed Force, however, Barry Allen remembered him and pulled him out, saving him.
