The conclusion of "Crisis on Infinite Earths" saw the creation of a new multiverse following the destruction of the first one at the hands of the Anti-Monitor. However, while the new multiverse may have been formed, the heroes of Earth-Prime are still unaware of its existence.Responding to a fan's comment on Twitter, "Crisis" showrunner Marc Guggenheim revealed that Earth Prime's heroes are still in the dark when it comes to the second multiverse. "The Earth Prime heroes don’t know there’s still a multiverse," he wrote. "Shh. Don’t tell em."
Of all the Arrowverse shows, this new multiverse most likely impacts The Flash the most. The fate of Earth-2's Jesse Quick and Harrison Wells is still up in the air after they were disintegrated by the anti-matter wave in the Season 8 premiere of Arrow. The fate of characters such as Breacher, Earth-3 Jay Garrick and Earth-3 Joan Williams is also unknown.
"Crisis on Infinite Earths," the latest five-show crossover between all the Arrowverse series, is now available on The CW's streaming service in its entirety.
