In the immediate aftermath of The Button, Thawne's corpse is taken to S.T.A.R. Labs, but he is resurrected via his connection to the Negative Speed Force and returns to the future, to examine the difference between the pre and post-Flashpoint timelines. He is present at Iris's house when Iris arrives with Wallace West, who Thawne brutally beats and denounces as a fake, before kidnapping Iris and bringing her to the 25th century. Barry arrives and is quickly beaten by Thawne, who reveals his identity as the Flash to Iris. Thawne subsequently shows the couple's future and tricks Barry into being trapped in the Negative Speed Force, but his nemesis gets connected to it and escapes. The pleased Thawne implores Barry to "ditch the loser sidekicks" and become his friend and partner, but his nemesis refuses and strips him of his speed. Nevertheless, Thawne vows to regain his powers and keep coming back to torment Barry, before being killed by Iris with a vaporisation gun.
