Arrowverse: Every Major Easter Egg, Clue & Reference To 'Crisis On Infinite Earths'

5. Crisis On Earth-X

The 2017 Arrowverse crossover, titled "Crisis On Earth-X", saw the wedding of Barry Allen and Iris West interrupted by an army of Nazi soldiers. The invaders were from the most barbaric of all the earths in the multiverse - Earth-X - and were led into battle by Dark Arrow, Overgirl and the Reverse-Flash. This led to an all-out war between the soldiers and the heroic team of The Flash, Green Arrow, Supergirl and the Legends.

Unlike the rest of the Crisis On Infinite Earths references, this one is quite minor and is more of an Easter Egg than anything else. However, given the fact that the title of the crossover was clearly inspired by the comic, it's significant enough to warrant a mention.

Who would have thought that the superheroes of the Arrowverse would be facing an even bigger Crisis two years later?
