Here is a link to just a few things Kyle Rayner has created and used as weapons using the Green Lantern ring.

I love that he is so creative, making giant bull dogs to eat a bad guy or an army of himself, or even an army of former GLs.
I was going to put Metamorpho earlier, but I forgot. Him and Plastic Man would be fun. What about an issue starring Metamorpho and Plastic Man, or Kyle Rayner and Martian Manhunter, and they have to fight Clay Face. Or put them all in there, with a few more villians like that.
I didn't think about that about Batman. Its very true, and very few characters allow that. You can make him in blue and grey, give him the yellow circle symbol, or a yellow bat, and no one really complains. Even if you give him a chin guard. Plus his costume is so great and iconic, you can just draw his silohet (spl?) from a distance and everyone knows who it is. Drawing Superman though would be such a priveledge, he is the 1st superhero after all.
It has been a dream of mine for a handfull of years now to draw for the Tick comic. He is awesome.
Also I wouldn't mind drawing for Cartoon Network comics, JLU or Teen Titans or Legion or even the Batman.
