10 Deadliest Enemies The Flash Ever Faced
3. Godspeed
A recent addition to the Flash's roster of enemies, August Heart was originally Barry Allen's colleague before becoming the speedster known as 'Godspeed'.
A police detective who appeared in 2016's The Flash: Rebirth, Heart became vengeful after his brother was murdered by a criminal. Struck by the same lightning which turned Barry Allen into the Flash, Heart initially began as the Flash's sidekick.
However, Heart was really using his powers to murder criminals and other speedsters, taking their powers for his own. Killing the main suspect in his brother's murder, Godspeed was born as a new superspeed threat to the Flash and a vicious serial killer.
Taking the law into his own hands, Godspeed planned to attack Iron Heights and kill the rest of the Flash's rogues, but the Flash and Kid Flash teamed-up to stop him.
After being imprisoned, Godspeed later sided with the Flash and Reverse-Flash to stop the villainous Paradox from erasing the Flash's history. It was in this team-up that Heart learned that the Reverse-Flash had killed his brother, before promptly being killed by the evil speedster too.
