liked Kyle on the League a lot during the Kelly-Waid-Morrison run, the way he kind of created an interesting younger brother dynamic and gave the League a certain... accessibility, perhaps? He made the Big Seven League seem a bit more like a collection of people than a collection of icons, in a way that the more businesslike, reserved John hasn't, but without the forced pandering of a Snapper Carr.
And now I'm flashing back to PAD's use of Kyle in YJ #6. I wish that there could be scans.
The thing with Kyle in that era of the JLA is that he was very much the one ordinary guy in the Big Seven lineup. Most of the others always had a Mission or were too alien to be accessible. Wally comes closest, but he had been a superhero since he was in his early teens, and that has had an effect on how he views the world. Kyle doesn't have that. Not only was he thrown head-first into the insanity of the superhero world, but his artist's eye draws him to the sticking points of a situation. The beauty is more beautiful, the wonder is more wondrous, and the horror more horrific. That's an amazing perspective to work with if you know how to best take advantage of it, which is why Morrison kept throwing Kyle into the crackiest aspects of the world-shattering event of the day.
