Wally West is reintroduced to DC continuity a week later in a "DC Rebirth" story. The story reveals that following the Flashpoint event, Wally became lost in the Speed Force for 10 years. While trapped, he came to realize that Barry had not been responsible for the mutation of the New Earth universe into Prime Earth but that an unknown entity had used Barry's time travelling as an opportunity to fundamentally alter reality. The fallout of the recent "Darkseid War" allowed Wally to try and reach out to his former friends in the hopes of either returning or warning them of the truth. Each attempt caused him to fall further into the Speed Force. After realizing that not even Linda (his traditional "lightning rod") could remember him, Wally sank into desolation and chose to appear before his uncle, Barry, one last time to thank him for the life he had given him. Just before Wally disappeared, Barry remembered him and dragged him out of the Speed Force. Wally's presence integrates his Pre-"Flashpoint" history to the new timeline to accommodate his existence, resetting his past and those who associated with him. Following a tearful reunion, Wally gave Barry his warning of the true source of the universal change and the dangers to come. Although the two decide to keep Wally's return secret from Iris based on Wally's own experience with Linda, Barry encourages him to return to the Titans, but also recommends that he don a new costume to reflect that he is the "Flash" rather than 'Kid Flash'. Wally goes to the Titans, and through both physical contact to Nightwing, Donna Troy, Arsenal, Tempest and Lilith Clay with the Speed Force reminding them of their memories with him, creating a new history. After an emotional reunion with his friends, he tells them of the situation. Wally believes that the unknown entity will attack again to prevent them from finding out the truth, which they will do together as Titans.
