You might know he's coming to The CW this fall, but you may have one question when it comes to The Flash:
Just who is The Flash?
A new trailer for this upcoming drama seeks to answer this question, featuring footage of Grant Gustin running around (quickly), along with narration by scientist Barry Allen, who transforms into this character due to a lightning strike.
My name is Barry Allen. And I am the fastest man alive, he says at the end of the clip. So there you have it, folks!
The Flash Season 1 premieres Tuesday, Oct. 7 at 8 p.m. ET/PT on The CW.
