The Flash Season 3: 8 New Villains You Need To Know About
2. Savitar
Another season of The Flash, and another speedster Big Bad. While there may be plenty reason to want something different (which, in fairness, they are doing as well), the presence of a villainous speedster does allow them to more directly challenge Flash's own powers, and hopefully they can put another twist on it with Savitar.
For the producers part, they have said that he'll be very different, and there's reason to believe them: Savitar views his powers as a gift from the Gods,even developing a cult following, and is able to lend and take speed from other objects, and create a force field around himself.
The idea of the cult is particularly interesting, and should mean he stands apart from his predecessors, while he'll also just be one of two Big Bads this year, with the potential for them to work together to defeat the Flash.
