Superman’s x-ray vision – So, where *does* Superman’s x-ray vision come from?
Many years ago in high school, my friend Andy and I were talking about superheroes — yes, I was a nerd back then, too.
I said, “You know, Andy, I was reading reprints of some of the old Superman comics, and I found out that, on Krypton, everyone had x-ray vision.”
“Really? I thought that Superman got his powers from Earth’s yellow sun.” Andy replied.
“Most of them, yes. And some strength from Earth’s lesser gravity. But his super-vision powers he inherited from his parents,” I informed him.
“Do you mean?”
“Yes! He had parental supervision!”
(apologies for the atrocious pun)
