As if the altered Flashpoint timeline wasn't enough, season 3 of The Flash will introduce a third villainous speedster for Barry to face off with; this time it's the "speed god", Savitar (who was yet to be cast). A lot of Flash fans groaned over yet another speedster acting as the big bad of the season, but executive producer Aaron Helbing promises a much different villain this time around. “[Season 3] is more about psychological warfare,” Helbing teased. "Everything about [Savitar] is different than Zoom or Reverse-Flash,” executive producer Todd Helbing adds. “I can’t go into too much detail, but he’s quite a bit different.”
In addition to Savitar, Barry will also have to contend with a second villain, Dr. Alchemy, who will be voiced by Tobin Bell of the Saw franchise. “[We’re] trying to have the powers that they both possess play off of each other,” Todd explained. “It’s not just, ‘Oh, I have to catch this guy and take him down.’ It’s like, ‘Crap, now there’s this other guy, Dr. Alchemy,’ who has these transmutation qualities [via] this Philosopher’s Stone. You start to learn what he does with this stuff and how the both of them are coexisting.”
The brothers admitted that the second season of the show found itself treading down a darker path, especially in the latter half of the season, when Zoom murdered Henry Allen in front of Barry. “[The] last five [or] six episodes [of season two] were pretty dark,” acknowledged Todd. “Zoom, in general, was dark, it even got darker than we probably anticipated. So we’re making a conscious effort to go back more toward the tone of season one.”
