"Plus, there are some truly epic moments and huge surprises that await our fans. And we’re doing them on a scale that’s bigger and bolder than our traditional Flash episodes. So yes, Armageddon is a lot more than just another graphic novel storyline. It’s going to be a true event for Flash and Arrowverse fans, old and new. Honestly, I can’t wait for audiences to see what we’ve got planned.”
