The official synopsis for The Flash: Armageddon reads as, picking up six months after the conclusion of season 7, a powerful alien threat arrives on Earth under mysterious circumstances and Barry Allen (Grant Gustin), Iris (Candice Patton) and the rest of Team Flash are pushed to their limits in a desperate battle to save the world. But with time running out, and the fate of humanity at stake, Flash and his companions will also need to enlist the help of some old friends if the forces of good are to prevail.

"Simply put, these are going to be some of the most emotional Flash episodes ever," said The Flash showrunner Eric Wallace said in a statement. "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."

The Armageddon event will be the first crossover where all parts will air as episodes on a single television series, rather than the parts airing as episodes on multiple series. This new approach was taken due to the COVID-19 protocols and restrictions. Unfortunately, it has already been confirmed that Melissa Benoist's Supergirl, and Tyler Hoechlin's Superman will not be making an appearance in the upcoming event. Showrunner Eric Wallace had originally approached both Melissa Benoist and Tyler Hoechlin about appearing in Armageddon, but were unable to do so due to scheduling conflicts and COVID-19 restrictions. It has also been revealed that Carlos Valdes will not be returning as Cisco Ramon in any capacity.

So far The Flash himself has faced some tough villains over the past few years, but if Tony Curran's Despero carries the same alien superintelligence and immense strength as he does in the DC comic book universe, he will most likely be one the fiercest foes Barry Allen has battled yet. The Flash airs Tuesdays at 8 p.m. ET/PT on The CW, beginning on November 16 with the start of Armageddon. Both Ray and Nora had also recently appeared in the hundredth episode of DC's Legends of Tomorrow. Currently, DC's Legends of Tomorrow and Batwoman have already begun airing their respective seasons.
