I confess that this is the one announced-to-date issue in this entire project that made me think "let's just get this over with" before I'd even seen it. So... let's get this over with.
Clockwise from top left: Dr. Mid-Nite (I think), Wildcat with somebody or other behind him, Wonder Woman, Grace, Wonder Girl, Black Lightning, looks like Captain Marvel, Superman with somebody else behind him, Mr. Terrific, Firestorm, Hawkgirl, Booster Gold, Starman, Plastic Man, Bulleteer (who never to my knowledge even met J'onn), Green Arrow, Stargirl, Aquaman--
Wait a second! Aquaman's dead! What's he doing here??
--Anyway. Donna Troy, Starfire, Batman, somebody whose white legs I don't recognize, Red Arrow, Geo-Force, Flash/Wally West, Ion/Green Lantern/Kyle Rayner (who was alleged in MARTIAN MANHUNTER #1,000,000 to have been a key player in a moment in J'onn's life when "everything seemed darkest," although that issue also presents J'onn as being alive and having his consciousness unified with Mars 853 centuries in the future--but then again BOOSTER GOLD #1,000,000 just came out this week, so I'm assuming that future is still in play), Power Girl, Adam Strange, Supergirl, Hourman, Damage, a boot that appears to belong to Dr. Light/Kimiyo Hoshi, Blue Beetle, Sand, Zatanna comparing fishnets with Black Canary, Green Lantern/Alan Scott, Huntress, Red Tornado, Steel, Flash/Jay Garrick, Hawkman with somebody behind him I can't identify, a green boot that might well belong to Green Lantern/John Stewart, Cyclone, a totally unidentifiable figure, Green Lantern/Hal Jordan, Vixen, Nightwing and Robin with Beast Boy and Raven behind them, Metamorpho. [Thanks to Adan and Don MacPherson for correcting some of my more egregious errors.]
A flashback to FC #1, obviously. But there's still a missing bit of information here: what led up to this, to recap, was that J'onn went to the prison planet in SALVATION RUN to see what was going on, disguised as Blockbuster; he saved Catwoman's life (in her own series), for which she repaid him by betraying him to Luthor; Luthor imprisoned him in a flaming cage, then left him behind when he brought everyone else back to Earth; and J'onn disappeared via boom tube in JLA #21. Who called up the boom tube and delivered him to Effigy and Dr. Light? And if that was Libra, what does he need Effigy and Dr. Light for?
Yeah, I didn't like that new uniform either.
Panel 3: The stretchy guy at left is the Elongated Man, who is also presently dead.
Panel 1: I guess he really is a "hairy-chested love god"!
"Malacandran": Martians call Mars "Ma'aleca'andra," as in "Malecandra" from C.S. Lewis's Out of the Silent Planet. "I know how it all ends": might that be some kind of reference to DC ONE MILLION?
I see that Superman is talking to himself again, and that he's still forgetting his participation in THE DEATH OF THE NEW GODS. And perhaps he should have kept a closer eye on Lois, you know?
The invisible chick in the bottom tier is Gypsy, created by Gerry Conway and Chuck Patton, who first appeared in 1984's JUSTICE LEAGUE OF AMERICA ANNUAL #2--one of J'onn's teammates from the mid-'80s "Justice League Detroit" era; after her own death, she was resurrected thanks to J'onn's intervention with his god H'ronmeer in MARTIAN MANHUNTER #12. And you thought Superman was a "proactive God"! Squashua points out that she's a human/Martian hybrid.
The Rose Center for Earth and Space exists in the real world, believe it or not.
Wait, so they kill J'onn in Central City (which I think is generally considered to be in the Kansas City sort of area) and then transport his body to New York City just so they can staple it to a model of Mars in the Hayden Planetarium? Seems like kind of an excessive gesture.
I'm betting all the framed pictures in panel 2 are redrawn versions of old JLA covers; anyone want to identify them? UPDATED: top row is something that looks fairly unidentifiable, JUSTICE LEAGUE #1, and a variation on THE BRAVE AND THE BOLD #28; lower row is something that's sort-of-but-not-really like JUSTICE LEAGUE OF AMERICA #258, and two I can't identify, although something keeps calling Darwyn Cooke to my mind in conjunction with the middle one. [Thanks to Don MacPherson again.]
A Turkey Tearror Broadhead is a very nasty-looking (but reportedly sort of ineffectual) arrowhead for shooting turkeys with a bow.
"My Favorite Martian."
Oh Jesus, Batman's a Skrull too?
"Green and white tore each other apart": the division between Green and White Martians first came up in the first Justice League series (as Garrie Burr points out), and reappeared in the early issues of Grant Morrison's mid-'90s run on JLA.
H'ronmeer was first mentioned in the 1988 MARTIAN MANHUNTER miniseries, I think. Ma'alefa'ak turned up in MARTIAN MANHUNTER #0, ten years later. These five pages are more or less a recap of the John Ostrander MM series.
The Josh Johnstone thing happened in MARTIAN MANHUNTER #20. The Bronze Wraith and the rest of the Justice Experience first appeared in CHASE #6.
The Fernus business happened in JLA #84-89, which Mahnke drew.
J'onn's fondness for Oreos was a running gag in the Keith Giffen JUSTICE LEAGUE series. They became "Chocos" as of MARTIAN MANHUNTER #24, an issue that is yet another example of the plural form of "Revelations."
Jeff notes that the Spectre moved J'onn's ancestral home to a pyramid in the Gobi desert--where there aren't actually pyramids, so I bet it won't be missed now that Superman's re-relocated it to Mars--in MARTIAN MANHUNTER #23.
Interestingly, the first Martian Manhunter story that Peter J. Tomasi wrote--back in SHOWCASE '95 #9--was also on the theme of death reuniting people with their loved ones.
In other news, FINAL CRISIS #3 has officially been bumped to August 6. Congratulations, everyone who guessed that issue in the contest! Email me at finalcrisis [at-sign-goes-here] douglaswolk period com, and we'll figure out what your prize is.
