True, that first gathering was just the heroes recounting individual tales...it took until their next issue for them to start working as a team. With a story by Gardner Fox and art by Everett Hibbard, Sheldon Moldoff, Bernard Baily, Chad Grothkopf, Howard Sherman, Ben Flinton, and Martin Nodell, the first super-team was gathered.
But who were the members of the team?
Batman began his unrelenting war against crime...and, hey, haven't we heard this before? Well, this was the original, coming out of the earliest part of the Golden Age (also called the "Earth-2" Batman, more on him here!).
legacy, and when the next Flash came back, so did Jay, and Jay then brought the whole Justice Society with him!
Man of the Hour
the Freedom Fighters for a time in the "retroactive continuity" of All-Star Squadron)...even messing around with time (as a android "descendant" of his proved, as did his son and successor, Rick Tyler!).
Master of the Mystic Arts
team with Batman, Superman and the Flash, as well as being a major player in the Crisis on Infinite Earths...and well beyond (with at least the identity of Dr. Fate, though not quite Kent Nelson all the time) getting a few series of his own!
...and you can see how the past helped to shape the future!
