A new poster for The CW's The Flash hints at an inevitable showdown for Central City's Scarlet Speedster.
"Speeding towards a showdown" is the message that appears on the poster, which sees Barry Allen suited up as the Flash, Speed Force electricity emanating from his body despite him apparently standing still.
As for who or what this threat could be, that remains to be seen. We do know the villain lurking in the shadows for the fourth season of the popular DC superhero series is The Thinker, who has gone to the trouble of populating Central City with even more metahumans after he played an uncredited role in helping Barry Allen escaping the Speed Force.
The first three seasons of The Flash have put Barry up against other speedsters -- Eobard Thawne, Hunter Zolomon and his future self, Savitar -- but the Thinker represents a new challenge. Instead of having to outrace Thinker, Flash will have to match wits with the cerebral-based bad guy.
Starring Grant Gustin as the Scarlet Speedster, The Flash airs Tuesdays 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.
