Savitar

Savitar, the self-proclaimed God of Speed, is the main antagonist in the third season of The Flash.

Opposed to the other speedsters who have been encountered by the Flash and his team before, Savitar does not seem to be human but is assumed to be the actual Hindu God of Speed. He appears in Central City after Flashpoint has been resolved and seems to be an ally of Doctor Alchemy.

He is voiced by Ciaran Hinds who plays Mephisto in Ghostrider: Spirit of Vengeance and will portray Steppenwolff in the upcoming Justice League film.
