Superman
This is probably a stupid question, but I'm wondering if somebody can explain something for me.
I read in another thread that Superman gains his powers from the Sun. In fact, I've heard that a lot, and its born out by the Superman comics I've bothered to read.
But, in the comic series Batman and the Outsiders, Superman battles one of the Outsiders, Geoforce, who has the ability to control gravity. Geoforce claims that Superman gains his powers from Earth's gravity, and proceeds to weaken him considerably with his gravity powers.
What's up with that?
