Because we know we can't due to COVID, but what could you give us for some kind of story that's 5 episodes long, that's a little bit bigger, and has a little bit more spectacle than your usual five episodes?' And I remembered my idea from 4 years earlier, and I said, 'I'll get back to you in a week.' I thought about the heart of the story, which is Barry's emotional journey. Wallace continued, 'So when The CW called and said, 'Hey, we don't want to do a crossover. It's the story of Barry's worst day ever, how it affects his marriage, and how it affects Iris.' So this is a 5-part special event, which means instead of a story that's revolving around Kara, Barry, and Oliver, this is just Barry. A crossover is a show with 20 heroes all in one scene taking place on 20 worlds, it costs a billion dollars, and it takes all this extra time to shoot.

Then cut to 4 years later, The CW called up and said, 'Hey we'd like to do not a crossover,' because I want to make it clear to everybody: it's not a crossover. But it at least started from the same place and the whole nine yards. 'It was with a different villain, not Despero. And because I'm that guy, I thought to myself, 'Well, if I ever get to do a crossover, I have this crazy idea', and it was the kernel of what is 'Armageddon',' Wallace told The Flash Podcast.

Because my first season on The Flash was season 4. I originally had an idea four years ago, and it was right after 'Crisis on Earth-X'. 'Two things combined kind of surprisingly, to create the storyline you guys are about to see. The Flash showrunner Eric Wallace explained in a recent interview just how 'Armageddon' came together and made it clear that the five-episode event isn't a crossover, but is instead a very intimate, and emotional story. But while the 'Armageddon' event will see The Flash (Grant Gustin) joined by heroes from other corners of the Arrowverse - including Batwoman (Javicia Leslie), Black Lightning (Cress Williams, The Atom (Brandon Routh), Mia Queen (Katherine McNamara) and more - this isn't exactly a crossover. The Flash returns next week, kicking off its eighth season on The CW with a five-episode event, 'Armageddon'.
