DC Comics has now cataloged a number of the 52 universes in the new multiverse. Here are my favorite multiple earth concepts due to their retro potential:
Earth-2 The original Earth-Two was my favorite earth of all. It was home of the original Batman, Superman, Wonder Woman, and other big guns who began their careers in the late 30s/early 40s. In the pre-Crisis on Infinite Earths multiverse, Earth-Two was populated by these older versions of popular DC icons. Their proteges included a graying Robin, the Huntress (daughter of Batman and Catwoman), Power Girl (Superman's Kryptonian cousin), and the orginal Infinity Inc.
The post-52 Earth-2 will be explored in Justice Society of America Annual 1 due this August. This earth will be similar, but not a perfect recreation, of the original Earth-Two. I'm not holding my breath, but I'm hoping that more mature versions of Batman and Superman can exist on this world, without having died and without having been retconned out of existence.
On a recent comic shop visit, I was excited to see some Batman and Superman Justice Society action figures as they appeared in the 70's All-Star Comics and Adventure Comics. This is a part of DC Direct's Reactivated action figures series. Previous collections in the series have included Super Friends and Kingdom Come versions of popular characters. The JSA figures make up the Reactivated series' Super Squad collection.
I'm hoping that these new JSA figures, which also include Hawkman and Wonder Woman, is a good omen--like a pointing toward a reactivation of these characters in comics. The Superman is graying-around-the-temples and the Batman looks like he did as a semi-retired super hero, while as Bruce Wayne he served as Gotham Police Commissioner. Earth-Two's Batman was killed in action in Adventure Comics #462, but I'm hoping that the Batman on this new Earth-2 might still be living.
Again, I'm not holding my breath. But at the very least it appears that Robin will be alive and well and that Huntress will be Batman's offspring. How Power Girl will fit in remains to be seen. This Earth-2 will resemble her former adopted home, but it's not an exact replica. Interesting.
