Ok, we're all aware that Superman gets his powers from the rays of our yellow sun and the closer or farther he is from the rays, that can make of break how strong his abilities are. But say he was deep underground where it's impossible for the sunlight to penetrate or even get down there. Will he be powerless? Also, what's with his enemies not utilyzing this weakness? Take him to the deepest/darkest of caverns and merc him, or just use ray guns that mimic red UV rays. Those are just my thoughts about it, what do you guys think?
