Of course it would be the Trinity. But more specifically Wonder Woman deserves the most respect.

Out of all the JL members (new 52) she is the only one who wasnt raised around Humans. She is the only one who has no ties to Humanity. Superman had the Kents, and the rest are humans. Despite this, she chose to stay in "mans world" and protect us. In a world where men try to dominate, she really is a beacon of hope for the rest of the population.

People think Superman feels like an outsider because of his alien heritage and the fact that he has god-like powers, along with other leaguers with god-like abilities, yet Diana is the only true god among them. She sees the way people look at her because of her divinity. Her dialogue with Aquaman shows this;

Aquaman "Thats all you do isnt it? Kill Gods and Monsters -- Normal people dont even exist for you. You're a God, you judge us".

Diana "None of you will accept me, EVER!".

Despite this she continues to fight for human-kind.

@klaus: Your post was good until you mentioned Aquaman.

Martian Manhunter, as he is the heart and soul of the JLA. He's the only hero who has absolutely no obligation to defend earth, but chooses to because he is a good person.

Out of all the members I would say Batman, Flash, Martian Manhunter, Elongated Man, and maybe even Aquaman.

@darktimecop: I would like that comment if Comic Vine had a like feature.

@crazyscarecrow: thanks man

@darktimecop: No problem.

Unlike many of the other leaguers, Hal was chosen to become a hero. He acted against the natural order (Sinestro and the Guardians) when he knew what they were doing was not right. Also unlike the other leaguers, Hal had to come back from having his reputation tarnished following the whole Parallax debacle.

He's now leading the GLC, not because he feels he's the rightful leader, but because he knows that he has to.

He's put enemies aside to fight for the greater good.

I think Batman and Martian Manhunter because they are underated, and they are dope.

@jonsmith: this is a perfect answer

Without superman there's no league.
