10 Most Underrated Arrowverse Villains

10. Time Wraiths

The Time Wraiths are some of the Arrowverse's more unsettling creations, acting as a reminder of what speedsters would face if they abused their abilities. Their purpose is somewhat similar to that of the Black Racer from the mainstream DC universe, and these beings are just as deadly and fear-inducing as their comic book counterpart.

The Dementor-like creatures are tasked with attacking careless time travelers as well as speedsters who break the rules of the Speed Force. This is done with the intent of preserving the proper flow of the timeline and the Speed Force's integrity.

Speedsters such as Barry Allen, Eobard Thawne, and Hunter Zolomon have all had near-fatal encounters with the otherworldly entities, with the latter being transformed into a version of the Black Flash that was forced to do the Speed Force's bidding.

It is unclear what became of the Time Wraiths following the Crisis on Infinite Earths crossover, though it is possible they perished along with the original Speed Force following its destruction.
