Next month, The Flash is racing back to The CW for season 8. However, Grant Gustin’s Barry Allen already has his work cut out for him. The alien conqueror, Despero (Tony Curran), has arrived on Earth, and he’s giving Barry an ultimatum. In seven days, everything and everyone the Flash loves will die. It’s the end of the world, if Barry does nothing. That’s why Barry is calling in his Justice League-adjacent super-friends for the first time since Crisis on Infinite Earths.

The CW has released its first trailer for The Flash season 8, which begins with the five-part Armageddon crossover event. That’s why Batwoman/Ryan Wilder (Javicia Leslie), Mia Queen/Green Arrow (Katherine McNamara), and Ryan Choi/The Atom (Osric Chau) are here to lend Barry a hand. The original Atom, Ray Palmer (Brandon Routh), is also returning for this story. And he’s the only one who notices that Barry’s been bulking up.
