The journey begins four years ago, at the end of 'Crisis on Earth-X,' which was in Season 4," said Wallace. Wallace continued, "I think it's the most emotional story yet for Barry, especially because of the ramifications of what happens as a result of 'Armageddon.'" In the same interview, Wallace explained that the story that evolved into "Armageddon" as it exists now began four years ago when he first joined the series as showrunner.

In fact, Wallace clarified that "Armageddon" is not a crossover at all, but a "five-part special Flash event, which means it's a Flash story, a Flash graphic novel that's a little bit bigger, a little bit wilder."

For one thing, according to Wallace, "Armageddon" won't "see a moment with 20 heroes and villains all fighting at once," both because the ongoing coronavirus (COVID-19) pandemic made it unsafe, but because it wasn't the story they were trying to tell. While Wallace did not specify what those things might be, he did say that "Armageddon" is unlike any other Arrowverse crossover that came before it.

While Gridlock is being transported to the prison, the convoy is attacked by a masked man, who tells Gridlock that he plans to destroy all the metahumans before approaching him with a lightning-shaped dagger.The Flash kicked off its eighth season with a five-episode "Armageddon" event, which has Barry Allen doing things both fans and showrunner Eric Wallace have been waiting eight years to see. They guide the plane through the buildings so that it lands safely in the river. A new metahuman named Gridlock, able to use kinetic energy, causes the plane to crash, so Barry, Nora, Wally, and Cisco team up to save it, and Nora provides Barry with a Flash Ring suit.

Barry asks Nora what will happen to him in the future, and she reveals that he never returned after disappearing in 2024 and that she traveled back in time to meet him. When Barry tries to send Nora home, Wally reveals that Nora's blood is saturated with negative tachyons, which prevents her from using the Speed Force or the Legends ' Waverider for time travel.

While Iris expresses excitement, Barry is concerned that she might change the timeline based on his own mistakes with time travel. The Flash team meets Nora, the daughter of Barry and Iris from the future.
