Only a few of the crossovers took advantage of that revolutionary idea by using heroes from history, and here are the two of them, as they teamed up with some fiery super heroines of the 1980s!
The Crisis Comes To 1942Flash, Batman, Green Lantern and Hourman) all coming back to put the final touches on Mr. Mind's early Monster Society of Evil, including Oom, who you can see attacking the Perisphere, the headquarters of the All-Star Squadron.
Freedom Fighters, but she also had flame powers which she had gotten during the formation of the All-Star Squadron) could go on a mission to Cape Canaveral.
Speaking with Nuklon and the 1985 version of the Golden Age Atom, Firebrand got assigned to check out Cape Canaveral, home of the Space Shuttle program at the time (as well as Terri Rothstein, who was Nuklon's mom and Firebrand's goddaughter).
This group approached Cape Canaveral in Florida in 1985, to find it besieged by American Indians of old...including Super-Chief (Flying Stag, also known as Saganowhana, leader of the Wolf Clan who gets super powers from a meteor in All-Star Western #117 of February-March 1961 and used them for the next two issues as well, to be later pulled out for massive team-ups, more on which in later columns....). For now, to the next issue and more guests!
Crisis At Canaveral
Firebrand and history's heroes battle the displaces native Americans (including a few more comic related ones, including Strong Bow of the Misty Mountains from an America before Columbus had landed who had premiered in All-Star Western #58 of April-May, 1951 - the issue that took over the numbering from the Golden Age JSA home of All-Star Comics) and Arak Red-Hand (shaman of the Quontauka tribe of the 8th Century who premiered in Warlord #48 in August, 1981, and had 50 issues of his own written by Roy Thomas).
The heroes were eventually successful stopping the Ultra-Humanite, left wondering how the greater Crisis would go (all the while the Golden Age Sandman had his adventure on an alternate Uranus).
A Long Night's Journey Into Day
A little later in the Crisis On Infinite Earths (if time has any meaning), New York found itself split into multiple time zones, in which were lost Terry Long (Wonder Girl's husband) and former Senator Walter Reilly (Firehawk's dad).
Lorraine Reilly was a young woman who was helping her father, when she was taken by the 2000 Committee, and subjected to tests that turned her into an approximation of Firestorm (without an attached other person) in Fury of Firestorm #17 (October, 1983).
Still new to the hero game, and giving herself a new costume in Crisis On Infinite Earths #9 (December, 1985), she and Wonder Girl went off to check on their relatives in Manhattan, to find it a time tossed city.
These three 1980s tales (and more) were reprinted in the Crisis On Infinite Earths Companion Deluxe Edition Volume 1 of 2018, and serve as a nice introduction of past heroes (some of whom had been seen before in JLA/JSA crossovers as well, tales which had occurred in the past, but will be covered in the future!).
