He took him from being a stereotyped "jerk" character into being one DC's best multi-dimensional ones.

SMith might not have wanted to give Guy the Vuldarian powers, but he used them well...One of the greatest moments in the 90's was Guy saves the president and is honored truly as an American hero...but Guy, rather than glorying in it, is more confused and contiplative about how his life has changed, and he has a heart to heart talk with SUPERMAN of all folks, about what it means to be the last of a dead race.

He had a purpose in Englehart's GLC (and incidentally, he was a far more casual killer there than anyone seems to remember) but the personality retcon that was silently introduced in "Legends" and "JLI" made the character just another in the list of irritating Giffen JL out-of-character retconned heroes (along the likes of Booster Gold, Batman, Blue Beetle, Martian Manhunter and Mister Miracle). Gosh, I hated those silly stories.

The GLC and the Guardians are supposed to have a fair degree of pomp and circunstance; start having them turn a blind eye to the likes of Guy Gardner and Kyle Rayner and their credibility suffers a lot. If you must have an assh*** character, pull a Takion/Firestorm and give him powers in a freak, random accident as those characters had.

I thought of that too, but the colors (Green, white, and black) are always the same. Actually, thats the only thing that is always the same. Some Laterns have shoulder-pads, some don't wear pants, and some just have different patterns and designs of their costumes for no rhyme or reason.
-I just don't think it works as well as it should.

He seemed to still have it in him in Blue Beetle #1.

In an issue full of great moments, Guy goes to see Ice. He sits on her bed and pours out his heart, but frames it all by saying that he thought Ice might be upset, and want someone to talk to. He tells her that she probably thought Scott was a good person, and she probably feels all broken up inside, like she wants to punch something.

And Ice just leans on his shoulder, and agrees.

Guy's expressions were heartbreaking. He and Ice were totally in character. And you could see what Ice saw in Guy, just for one page...

I like the way GLC is dealing with something much like that with the new Korugarian GL. And it's a neat idea - really, after their experience with Sinestro, having a new Green Lantern would be not unlike having, on Earth, a nice, friendly Superman type show up saying "Just here to help" ... and he's wearing a Nazi SS uniform.

Beyond that, I'd say it has a lot to do with the practical difficulties of designing costumes for so many alien species and cultures. Heck, imagine a society where green signifies death the way black does for Western culture! "Run! It's DEATH Lantern!"

Why does the Green Latern Corps... a police or military unit, not have real uniforms like every other police or military unit? I could see having different classes or something, to make sure all of the main guys get different ones, but it seems like every Latern's costume is totally random.

The only way I can imagine Gardner working for me is if he's relegated to non-ring-wielding supporting-cast status. Imagine if Johns had not been such a wuss (by pushing the reset button for everything) with Rebirth, and left Guy as just a dude running a bar. Then he'd be sort of like Bibbo for the GL comic. (Earth has too many Lanterns anyway.) But if they'd actually take Guy's power ring away permanently and develop his character from that point, who knows? He might end up being actually interesting, instead of a walking cliché with a horrible haircut.

How cool would a GLC cartoon with Guy as the lead character be?

Incidentally, is the current Green Lantern Corps series any good?

The guys at DC might hate the Giffen Justice League, but they ain't crazy.
