Why is ‘Crisis on Infinite Earths’ so significant?

For many years, fans eagerly anticipated Crisis on Infinite Earths. First of all, the story is based on a DC Comics series of the same name, which debuted in 1985. What’s more, the events of the Crisis on Infinite Earths television adaptation were foreshadowed in The Flash Season 1 Episode 1, more than five years before Crisis on Infinite Earths premiered on The CW.

Following suit with previous crossovers, heroes across the multiverse united against a common threat, but Crisis on Infinite Earths was particularly significant in many ways. It was Batwoman’s first team up as the freshman Arrowverse show, and Arrow’s final collaboration because the series has ended.

Another area of importance is a potentially expanded roster of heroes, despite Arrow’s conclusion. It was the first time that the Black Lightning narrative was integrated into the Arrowverse, and due to the outcome, the show could become incorporated into the shared TV universe moving forward.

Before Crisis on Infinite Earths, the heroes were scattered across different realities, but the consequences of this crossover changed things. The events resulted in a newly rebooted universe in which all of the heroes exist in a single reality.
