Alternate Earths: Earth-1A and Earth-2A

While most tales involving the Justice League and Justice Society prior to Crisis on Infinite Earths have been relegated to Earths One and Two, respectively, there have been notable exceptions as to their members. Specifically, the "Big Five" plus two whose tales were continuously published on Earth-Prime (our world) since their inception in the late 1930s/early 1940s and through the decades between the Society's last Golden Age tale and the League's first Silver Age tale. 

The so-called Big Five, these were Superman, Wonder Woman, Aquaman, Batman and Robin. And it was this quintet who became the core group known as the Super Friends*, as four Justice Leaguers and one Teen Titan were selected to training aspiring heroes Marvin White and Wendy Harris. Shortly after, they would turn their attention to the extra-terrestrial shapechangers Zan and Jayna, the Wonder Twins. While reference within the Super Friends and Justice League tales assert that these two groups existed concurrently on the same Earth-One, some oddities in the Super Friends tales do not quite line up with the League's mainstream continuity. As such, their stories may have occured on Earth-One, but not quite as they were written within the comicbook published on Earth-Prime**. 

As mentioned after the Crisis by author Roy Thomas, the dispersed energy of the seven superheroes who departed the 1940's All-Star Squadron had to be compensated by newer heroes taking their place. While Neptune Perkins assumed the place of his fellow former Earth-Two All-Star colleague Aquaman and Dan the Dyna-Mite substituted for Robin, three new heroes from a third pre-Crisis Earth... quite probably Earth-Eight... in Iron Munro, Flying Fox and Fury took the place of Superman***, Batman and Wonder Woman****. While their tales as the Young All-Stars would not be exactly as would've been the All-Star Squadron's tales with the "Big Seven" still active, many elements would be similar making the young heroes' adventures homages to untold Earth-Two Squadron tales*****.

Of course, the remaining duo of those seven characters included the Battling Bowmen known as Green Arrow and Speedy. While they were pulled from their native time period in the late 1940's due to their battle alongside the Seven Soldiers of Victory versus the Nebula Man, there were still stories told specially about the Earth-Two version through the late 1950s. We will consider this in the future.

* The Super Friend's actual Earth-Two counterpart team would the Super Squad, consisting of a core group with the Justice Society who... like the Justice League... were tasked with training a second generation of younger heroes.

** One such example of this is when Red Tornado mentioned his used of time travel referenced Super Friends issue# 8, while engaging in this feat a second time in Justice League of America #155.

*** E. Nelson Bridwell among others postulated that the golden age Superman's stories referencing Daily Planet instead of Daily Star, and a bald Luthor instead of a red-haired Luthor, transpired on Earth-2A. If so, then these same stories were also told on Earth-Two, as referenced by the tale of the Powerstone... where both a bald and red-haired Luthor claimed the object for himself.

**** Other members of the Young All-Stars including Tsunami, Sandy, Tigress would be reflections of Jayna, Zan, Wendy and Marvin with the Super Friends.

*****As shown by the accompanying picture, at least briefly before the inception of the Young All-Stars, members of the Freedom Fighters took the places of the missing "Big Five" in the Squadron. Although curiously, in the retroactively altered picture, golden age Green Arrow and Speedy remained until later wiped from existence!
