In Supergirl Season 5 Episode 9, which is the first episode of Crisis on Infinite Earths, we see different Earths in which I can recognize Titans and the different Earths of Arrowverse like Earth 1, Earth 38, and Earth X.

Edit: There have been a lot of Earths mentioned in the other Crisis on Infinite Earths parts. What are the other universes that are mentioned in the other scenes and episodes?

Screenrant answered it pretty well:

Earth 89: Tim Burton's Batman Movies

Tim Burton's Batman films are represented in one quick cameo, which confirmed it as Earth-89. Danny Elfman's familiar Batman theme plays as the Bat-Signal burns bright in the red skies over Gotham City. This is observed by a man in a trench-coat and fedora, who mutters "I hope you're watching, big guy." The observer is reporter Alexander Knox (Robert Wuhl), who was the first to report upon The Joker's crimes in the 1989 Batman movie.

Earth 9: DC Universe's Titans

We briefly see red skies over Titans Tower in San Francisco, before being treated to close-ups of a disturbed looking Hawk (Alan Ritchson) and an upset Jason Todd (Curran Walters).

Earth 66: 1966 Batman TV Show

One of the first cameos confirmed for Crisis on Infinite Earths was Burt Ward, who played the Dick Grayson Robin on the 1966 live-action Batman series alongside Adam West's Batman. Ward's cameo is short and sweet, as we see Dick Grayson walking a dog while wearing a red sweater with yellow and green trim suggesting the classic Robin costume. Suddenly, the skies turn red and sinister, prompting the former Boy Wonder to shout "Holy Crimson Skies Of Death!" It isn't a big scene, but it is enough to confirm the 1966 Batman show as the Earth-66 of the Arrowverse.

Other Earth's you might already know, which are:

Flash, Arrow, and Batwoman related characters live here.

Earth 38:

Supergirl's universe.

Earth X:

With the Ray, evil Arrow and Supergirl, part of older crossover.

Earth 16:

Jonathan Kent (Superman's son) landed there by mistake. And it was prominently featured before in Legends of Tomorrow season 1 with a dark future of Earth 1 heroes in 2046.

Earth 2:

Mentioned by Oliver (didn't appear) which got destroyed in Arrow season 8 with a single survivor Laurel Lance.

Unknown Earth:

Earth (not stated)

Earth of Black Lightning

From Crisis: Episode 4 (Arrow) & Episode 5 (DC's Legends of Tomorrow)


Previously destroyed, now home to the Justice Society of America & Stargirl (new CW series in course)


Home to the the Titans


Home to the the Green Lantern Corp - possible reference to Green Lantern tv series on HBO-Max


Home of The Swamp Thing


Home to Doom Patrol

Earth-96 (rebooted?)

Brandon Routh is Superman

Earth-96 was inspired equally from the first five Superman movies and the classic graphic novel Kingdom Come. It was named in honor of the year in which Kingdom Come was first published - 1996.


Previously Earth-1, now apparently a combined Earth which is home to:

  • The Flash
  • Supergirl
  • DC's Legends of Tomorrow
  • Batwoman
  • Black Lightning - may previously have been Earth-1
  • Superman & Lois - new CW series in course

    This answer would be greatly improved if instead of simply identifying actors, you would identify the show or movie. For example: "Earth 99: 'Batman: The Animated Series' (?): Batman (Kevin Conroy) has retired and can only move thanks to an exoskeleton."

    Earth 99 is not the Animated Series Earth it just features a voice actor from the show.

    Ah. Okay, perhaps Earth 166 would be a better example then? To avoid pedanticism, I'll amend the suggestion to say this: It would improve the answer to identify the significance of particular casting choices. Kevin Conroy wasn't just random casting; he is famous for playing that specific character on a particular show. Ditto Tom Welling and Erica Durance. Ditto John Wesley Ship. Ditto Brandon Routh. Don't get me wrong -- it's a great answer, and pretty thorough; I was just suggesting an improvement. Even Birds of Prey could be noted better as it was only ever a pilot episode

    I'm now wondering if they tossed in a reference to the Aquaman pilot that never became a series...? ;-)

    Note: The question mark in my original comment was there to indicate that it's a question as to whether that is actually that universe, or just a fanservice reference to that show. After all, if Conroy's Bruce Wayne walked with an exoskeleton, it also serves as a reference to Kingdom Come's Batman. Question: is Earth 99 definitely not the Animated Batman universe, or just a case of "they didn't quite specify"?
