So perhaps Superboy-Prime unknowingly possesses the most incredible power of all -- the manipulation of reality.
This idea -- that residents of Earth-Prime have the ability to alter reality on the other Earths (which after all were CREATED by the thoughts of various persons on Earth-Prime) -- is very intriguing. No, scratch that, it's brilliant. And the fact that you could come up with it tells me you'll never be writing for DC.
I'd like to see stories written around this idea. But don't waste your brainstorm defending DC, when you know its more profound and interesting than anything they actually intended. Seems to me the most creative ideas in modern comics are generated by fans trying to explain why comics don't actually suck despite all evidence to the contrary. If we could just harness that brainpower and use it to produce a new line of comics, I for one would be collecting again.
