A new promo for Justice League teases the origin story for the DC Extended Universe's The Flash. Played by Ezra Miller on the big screen, the specific iteration of the Scarlett Speedster made a cameo in Batman V Superman: Dawn of Justice, but will join DC's finest heroes for the first time this year - as they come together to stop Steppenwolf (Ciarán Hinds ) and his legion of Paredemons from conquering the Earth.

Though we know he is recruited by Batman (Ben Affleck) to join his superhero squad, we know little about Barry Allen's canonical background and origins in the DCEU. Based on Batman V Superman, it appears that Bruce Wayne first learned of The Flash through Lex Luthor's (Jesse Eisenberg) secret files - which also had short surveillance clips of Wonder Woman (Gal Gadot), Aquaman (Jason Momoa) and Cyborg (Ray Fisher). While we now know Diana's DCEU backstory, Arthur Curry's backstory will be explored more in next year's Aquaman, whereas Victor Stone's origins look to tie into the plot of Justice League. That leaves the question of how The Flash came to be in the DCEU.

The following teaser was posted on Justice League's official Twitter account, showing Barry in his fight suit and demonstrating his super speed ability.  “After an electric storm, Barry Allen was never the same,” its caption reads. Despite the tease, however, this is not a confirmation that the upcoming blockbuster will cover Barry's superhero origins in detail.

Obviously, the origins of DC's fastest man alive is not a total mystery. The CW's TV series The Flash did a great job of showing how Barry Allen's alter-ego was born (struck by an artificial lightning) and it seems safe to assume that the DCEU version will not be changing too much about that backstory. Still, it might be nice to learn more about Barry's history in the DCEU in Justice League, given that his own solo movie will instead focus on adapting the Flashpoint comic book narrative.

How the DCEU approaches The Flash as one of its cornerstone characters remains to be seen, of course. Still, fans can expect to get a clear idea of where Barry is coming from, once Justice League hits theaters in less than two months. The project has been undergoing revisions/reshoots supervised by Joss Whedon, as a result of director Zack Snyder's sudden departure from the movie due to personal tragedy. Snyder is still involved with Justice League, however, and is expected to help finish the film ahead of its release.
