The first thing that you have to remember here is that Mars does not matter in the grand scheme of DC Comics continuity. Krypton does. Gotham City does. To a much lesser extent, Themyscira does. Casting a net more broadly, as has been mentioned in a couple of my podcasts, Atlantis matters to both
Marvel and
DC Comics. But Mars? I don't think rates all that highly anywhere, outside of
Topps Comics. The 20th Century made a lot of dismissive mention of the Red Planet, and like the moon, the popular consciousness read it as a generic location of dubious value to fantastical comic book stories.
And so, the first half of the Post-
Crisis on Infinite Earths revisionist history of DC published in 1986 is mighty concerned about Oa, prehistoric Earth, World War II... all those other places I mentioned. Without a comprehensive reread though, no mention of the planet Mars, or any of its denizens. Moving into the second half, they still devote a lot of pages to WWII, and a little bit of the post-war years. The one true Earth was still a cooling mass, however, so from there we leap to Task Force X and the conception of Aquaman. That famed rocket from a doomed planet had been launched in the first volume, and finally landed in a corn field near Smallville. A nigh-adolescent Bruce Wayne saw his parents gunned down, which gets a bit hinky with the relative ages of the DC Trinity. Phantom Stranger, Captain Comet, and the creation of Princess Diana arrive next. Well, one figure does fall between Comet and clay baby Wonder Woman...
Warrior J'onn J'onzz, exiled into the parched Martian desert, was teleported accidentally to planet Earth by the famous Professor Erdel. This Manhunter from Mars knew the time of heroes had not yet come, and so remained in hiding, disguising himself as a police detective until, at last, he could allow the world to know of his existence.
There's a lot to consider there. Firstly, that was two sentences. I choose to offer long, sometimes tortured sentences as part of my personal expression, so you might call me hypocritical for pointing that out-- but dang! Next, the fact that in a rare instance of DC offering mixed caps in a canon story, only the Js are capitalized. Okay, I might be "considering" too pedantically. How about how the late Silver/early Bronze status quo begun with
"...And So My World Ends!" seems to still be in place, with that "warrior" bit in particular pushed back against by the 1988 retcon? We're also in a vague pre-heroic age, with the best marker being the conception of Raven on the next page. The creative team on this book had come up with that character to be a member of the New Teen Titans, and the book's artist was presumably working out how his Wonder Woman would also debut in her late teens/early 20s in her new history. Therefore, at the time of publication, it would be fair to assume Detective John Jones was around in the late 1960s. Couldn't be much further back than that, if we want to keep Superman and Batman around 28-30 years old. While a handful of stories alluded to a further period setting, it would be another eight years before
parity with his initial date of publication was established in
Zero Hour: Crisis in Time #0.
In another short-lived stand for this continuity, the entire World's Finest trio launches the modern heroic age, placing Robin ahead of the latest version of Flash, Green Lantern, the Atom, the Hawks, Aquaman, Captain Atom, Green Arrow, and Blue Beetle. We see Starfire as a child, Cave Carson, the Challengers of the Unknown, Adam Strange, the Sea Devils, and Dolphin. Curious chronology ahead of their key super-team revival...
This was now the Silver Age of heroes, and some of the greatest who ever lived banded together to fight evil on Earth and throughout the stars. Inspired by the wartime exploits of the famed All-Stars and the Justice Society, these young heroes took the name the Justice League of America.
Because John Byrne's
Man of Steel had already rolled out, we knew that Superman would be excluded. Pictured as the core line-up were J'onn J'onzz, Aquaman, Barry Allen, Batman, and Hal Jordan. A scale Ray Palmer Atom was placed just outside the framing of this team inside the old badge logo of the JLA, with the floating heads of Oliver Queen and Katar Hol on either side. Not a bad guess, but this line-up was never properly executed in the comics. The Caped Crusader was eventually excluded, at least as a founder, though he inevitably engaged with the JLA early and often in this retcon. DC eventually settled on
a quintet in 1988, capped by Black Canary.
Jemm, Son of Saturn got a mention as a contemporary of Firestorm, Firehawk, and the Warlord Travis Morgan, oddly predating the retroactive continuity armored Gardner Grayle Atomic Knight, as well as Baron Winters of
Night Force. These were mostly continuity charity cases, only getting a nod here by proximity to publication date. Jemm was originally a
Son of Mars, who played heavily in the fields of post-apocalyptic Bronze Age New Mars stories, and his Saturnians were eventually retconned into literal Martian clones by Ostrander/Mandrake. It's nice for us, since none of the solo Manhunter from Mars adventures rated a mention, nor his predecessor,
Roh Kar. Instead, as ever, and another gift of the zeitgeist, the Alien Atlas is solely represented in this period through his affiliation with the mid-80s Justice League (generally appended with "Detroit" to define the line-up of Batman, Elongated Man, Zatanna, Steel, Gypsy, Vibe, Vixen, and Aquaman.
From there, we get into the weeds of para-
Crisis on Infinite Earths material, with a heavy emphasis on developments during and spinning out of
Legends, including the line-up of the first six months or so of the
Justice League relaunch (soon-to-be-International.) So that's Dr. Light II, Captains Atom and Marvel, Mr. Miracle, Guy Gardner, Black Canary, Blue Beetle, and Dr. Fate. They're followed by the Suicide Squad and, ugh, Post-Crisis Wonder Woman. It makes my skin itch when people rave about the female leg of the DC Trinity arriving after freakin'
EVERYBODY, just so Perez could treat his Simonson
Thor retread as though it were a brand new shiny thing. And then from there is a toboggan ride through the potential futures, most especially the Legion of Super-Heroes 30th Century, that will be ripped to pieces to wipe the butt of every reboot from here through the next five decades and counting.
