The New 52, Corrected: Kyle Rayner, Green Lantern
What Happened: This would be the new name for Green Lantern: New Guardians. Initially, it was about DC deciding they needed someone to collect the rings like they were Pokemon, and they chose Kyle Rayner since he wasn't doing anything.
What I'd Change: We know that Hal Jordan is DC's main Green Lantern, and that's cool. But here's the thing: The guy pretty much exists in space. Same with Guy Gardner and John Stewart. Sure, Hal hangs out with the JLA from time to time, but that's about it. Earth needs a Green Lantern, and I think Kyle could be it. I'd try to make this a pretty traditional, old-school kind of superhero comic in that Kyle would be one of the few superheroes with an actual secret identity, and a cast of people who WEREN'T involved in his superhero life at all. There was a time when both DC and Marvel were filled with these, and now its pretty much just Spider-Man. At this point a superhero with a dual life would be unique, so why not go for that?
Why: Because Green Lantern: New Guardians is boring as shit. And typically has bad art on top of that. But also because Kyle feels kind of aimless right now. Sure, he's collecting all the rings' powers but is he really going to do anything with them? Kyle could use a return to form and hopefully in that find a brand-new fan base.
