In 1963, DC Comics began an annual crossover story involving the Justice League of Earth-One and the Justice Society of Earth-Two.

It was called “Crisis on Earth-[fill in the blank]”

Details here.

Earth-Prime was a favorite of mine.

In 1985, DC published the last JLA/JSA crossover.

“Crisis on Infinite Earths” was DC’s first attempt at streamlining and consolidating their timeline by eliminating the multiverse.  They’ve since backtracked and went from a single universe to a multiverse again.

Somewhere along the line they had a “Crisis on Earth-X” story.

And now they’ve adapted it to the CW’s Arrowverse.

So far, it’s awesome.

So much better than last year’s “Invasion!”
