As the Crisis on Infinite Earths' crossover has ravaged the Arrowverse and more, viewers have seen several universes (designated by "Earth" plus a number and sometimes a letter) destroyed by the anti-matter wave unleashed by the Anti-Monitor.
Spoilers for the crossover follow…
In the first three parts of the crossover, set in the ninth episodes of Supergirl Season 5, Batwoman Season 1, and the Flash Season 6, viewers have also gotten to see a great deal of cameos as these universes die with
Earth-9: Home of the Titans TV Series
Earth-38: Home of the Supergirl TV Series
Earth-66: Home of the Batman '66 TV Series
Earth-89: Home of the Batman 1989 Movie
Earth-90: Home of the 1990's Flash TV Series
Earth-203: Home Of the Birds Of Prey TV Series
Earth-X: Home of the Arrowverse Freedom Fighters
All now destroyed by the anti-matter wave.
(The universe belonging to the Black Lightning TV Series is also mentioned to have been destroyed but there is no official designation for that Earth in the Arrowverse. Maybe Earth-18, or Earth-77 would work?)
The first issue of Crisis on Infinite Earths Giant shows us several more Earth's lost to the wave including one TV series it is surprising we haven't seen referenced yet, the Wonder Woman TV show.
Earth 76 (because the first season of Wonder Woman debuted on April, 21 1976):
(Don't anyone tell Andy Mangles … he'd probably disagree on the Earth designation … Though DC should too... ) Another Earth lost is the home to the Superman animated serials done by the Fleischer brothers, Earth-F
We also get two more universes lost: Earth-N52
Bethany Snow is our main New 52 focus character. Another Marv Wolfman created character from The New Teen Titans #22, though known mostly in the New 52 from all the Channel 52 backup features ran in the back of comics from the New 52 era. So the universe home to the New 52 relaunch, destroyed in the Arrowverse Crisis. Ironic?
And another Earth that was destroyed in the original Crisis on Infinite Earths, Earth-D
Created in 1999 by Marv Wolfman and Paul Ryan in the Legends of the DC Universe: Crisis on Infinite Earths one-shot, this universe was the first time Wolfman created new material tying to Crisis on Infinite Earths. The universe was home to diverse versions of the heroes known as the Justice Alliance, though here Superman and Supergirl were a married couple and not cousins. However, once again Wolfman destroys this universe in another Crisis… (Though we don't get to see the destruction of this Earth in the issue.)
So the list of destroyed Earths goes up by four in this comic book tie-in written by original Crisis on Infinite Earth's author Marv Wolfman and the show runner/overseer for the Arrowverse version Mark Guggenheim.
How many more Earths will we lose in Crisis on Infinite Earths Giant Issue #2?
