I tried everything. I even tried to manipulate the Speed Force but let me tell you, the Speed Force... the Speed Force does not like its rules being broken...
Time Wraiths are supporting antagonists in the 2014-2023 TV Series The Flash and the overarching antagonists in Season 2 of its 2016-2022 spin-off, DC's Legends of Tomorrow. They are the sinister enforcers of the Speed Force that hunt down speedsters who breaks the Speed Force's rules. A total of four Time Wraiths have been shown.
The first Time Wraith encountered appears after Barry has travelled back in time to have Eobard Thawne figure out the Speed Force equation. Time Wraiths appear to those who have altered the timeline.
History
Barry first encounters a time wraith during his travel through the time-tunnel, the wraith angrily flying at him. It later appears in Barry's office in the GCPD, much to the shock of the police officers in the precinct. They fire their guns at the wraith which is not affected by the bullets at all. After seemingly searching the precinct, it leaves.
It later resurfaces at S.T.A.R. Labs. To save themselves from it, Cisco and Caitlin lock themselves up in the cell of Hartley Rathaway. They eventually team up with Hartley who uses his gloves to drive away the wraith. Before it returns, Barry travels back into his time. Although it pursues him down the accelerator, Barry from the past tackles it down and the future-Barry returns to his timeline.
The Wraith then follows Barry into the future and proceeds to age him to death until Barry is saved just in time by Hartley Rathaway, who due to the changes Barry made in the past has reformed and blasts the wraith to dust with his sonic gloves.
During the final confrontation between Barry and Zoom, Barry creates a time remnant that sacrifices himself to disable the artificial magnetar Zolomon was looking to power. This action provokes a pair of Time Wraiths, which attack the defeated Zolomon, who has caused much more damage to the Speed Force than Barry. Upon being attacked by the wraiths, Zoom decays and is then abducted by the Wraiths who drag him into the speed force. Zoom later appears as an enforcer of the speed force's rules himself.
Another Time Wraith is encountered when Barry enters the Speed Force to save Wally West. The Speed Force gives Barry the chance to save Wally, but claims that Barry has to outrun an approaching Time Wraith first. Barry speeds off immediately and escapes the Wraith pursuing him despite the Wraith's efforts to stop him.
Barry and Nora attracted the attention of a Time Wraith when they time traveled to stop Cicada. However, when Hunter Zolomon/Zoom started go after them in the second point in the past that they visited, demon choose to go after Zoom.
