After three seasons of speedster villains, The Flash is headed in a new direction. ScreenRant's Kevin Yeoman reports that, during The CW's panel at the Television Critics Association press tour, it was announced that the series is "likely done with speedster villains." Additionally, Barry's sad days are numbered, as Season 4 "will find the lightness that was in the first two seasons."
Season 1 pitted Barry against his most personal nemesis: Reverse Flash. The second season saw the debut of Jay Garrick and the villainous Hunter Zolomon, aka Zoom. In Season 3, the Scarlet Speedster took on Savitar, the God of Speed. Each of these villains have been speedsters who pushed Barry to the limit of his own capabilities.
In the upcoming Season 4, Clifford DeVoe -- aka The Thinker -- will be the main antagonist, which makes good on the claim made above. Debuting in 1943’s All-Star Flash #12, DeVoe was a failed lawyer who turned to crime when he realized that his criminal clients had skills, but not smarts. This being the case, he became the brains of the operation for multiple career criminals. Using a device called the Thinking Cap, DeVoe can also project mental force and occasionally control other technology. Other incarnations of the Thinker have surfaced over the years, including Clifford “Cliff” Carmichael and Des Connor, so it’s possible that The Flash will combine these different versions into one character. At the time of writing, it's unclear how the show will adapt the character, though an unconfirmed character description has surfaced online.
Starring Grant Gustin as the Scarlet Speedster, The Flash returns Tuesday, October 10 at 8 p.m. ET/PT on The CW. The series also stars Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Candice Patton, Danielle Panabaker, Keiynan Lonsdale and more.
