Green Lantern Kyle Rayner, in the costume designed by Jim Lee (I believe), from the JLA line by DC Direct.
As much as I like his original costume I think this one is my favorite. It's similar to, or might even be the same as, his Ion costume, and while I know very little of that time in his life, I think it's cool. Of course, the costume he got during Countdown is also nice, and DC Direct is releasing a figure of that in Blackest Night Wave 3 sometime next year.
It takes nearly a minute to fall from this height, and despite what you may have heard, you're likely to stay concious the whole way down. Thoughts like that keep me warm at night. - Batman (though I can't prove it)
