DC Extended Universe Thread (DCEU)
That's how it starts. The fever. The rage. The feeling of powerlessness. That turns good men....Cruel - Alfred.
This may be the only thing that I do that matters - Bruce.
Stay down, if I wanted it, you would be dead already - Clark.
Giffen's and Bisley's Lobo.
"You address omnipotence. Tread carefully."
I would think Green Lantern.
For most of Hal Jordan's career as a Green Lantern, the title has done steady but unremarkable numbers. It was canceled, in fact, and made a backup in Flash for a while, and then in an effort to bring it back they paired him with Green Arrow, to buoy sales.
Then for years it sold medicore numbers, regardless of what they did. Good stories, bad stories, good art, bad art -- this was the reputation of the title when Englehart was given the reins, that no matter what you did the numbers wouldn't move.
Then Englehart doubled them. But the book was a victim of it's success -- Action Comics Weekly needed a strong lead and GL was it. Well, the book was canceled, Englehart and Staton left, and we had some of the worst GL stories ever in the aftermath (despite guys like Priest and PAD working on those stories). The Englehart era didn't really constitute an expansion -- 'Tales' was one three issue mini,a nd the subsequent "Tales" Annuals were widely spread out.
Then they relaunched and it was a success that seemed to support a lot of books but none of them really gaining star-status.
Green Lantern was paired with Green Arrow in the early '70s as a hail Mary pass to save the book, but it didn't work. So Green Lantern/Green Arrow finished out their run in THE FLASH and then Hal had more solo stories and occasional team-ups with Flash in that book. When they decided to revive GREEN LANTERN again, the title started out as a bi-monthly, and Hal was paired up with Green Arrow again (with Black Canary also being featured). The book was boosted to a monthly and that was the status quo for a couple of years (Green Lantern/Green Arrow/Black Canary/Air Wave). Green Arrow and Black Canary were also featured in WORLD'S FINEST COMICS at the same time--so you could say they were doing better than GL. By 1980, GA and BC had left and now Green Lantern finally had his own monthly title again (it only took a decade).
Marv Wolfman integrated his ideas in the various books he was writing. So ideas about the Gordanians, Psions and Vegans permeated his GREEN LANTERN and NEW TEEN TITANS books and those were spun off into OMEGA MEN (by Roger Silfer and Keith Giffen)--which in turn gave birth to Lobo.
Englehart had an even more cosmic vision for GREEN LANTERN and Green Lantern's cosmology is ever present in CRISIS ON INFINITE EARTHS (written by Wolfman)--Hal doesn't take part in COIE only because a lot of this cosmic stuff is going on in his own book (with Guy Gardner gaining his place as Green Lantern). After COIE, all of those ideas spread out to the other DC books. And in JUSTICE LEAGUE, you have the Rocket Reds, Guy Gardner and G'Nort. And other big event books like MILLENNIUM and INVASION used a lot of the Green Lantern cosmology.
This.
Justice League is the 3rd biggest in the general psychosphere thanks to cartoons, upcoming movie, and the involvement of Superman and Batman.
Green Lantern is the 3rd biggest in comics, or at least until the creative team shift 18 months ago.
Wonder Woman is probably the 3rd most recognisable individual though. She doesn't really have a franchise to boast, neither in comics nor the general public's view, but everyone knows who she is, more so than Green Lantern or the Justice League.
In short, the answer depends on your interpretation of the question.
JLA without a doubt. Hundreds of Super friends and and JLA cartoons. Thousands of issues since the begining of the silver age.
