“It’s not real. And beyond that, when you’re dealing with characters, they exist on paper. They’re real in that context. I always say they’re much more real than we are because they have much longer lives and more people know about them. But we get people reading superhero comics and going, ‘How does that power work? And why does Scott Summers shoot those beams? And what’s the size of that?’ It’s not real! There is no science. The science is the science of ‘Anything can happen in fiction and paper’ and we can do anything.
“We’ve already got the real world. Why would you want fiction to be like the real world? Fiction can do anything, so why do people always want to say, ‘Let’s ground this’ or ‘Let’s make this realistic.’ You can’t make it realistic because it’s not. So basically Batman is 75 years old, and Robin is 74 years old. They don’t grow old because they’re different from us. They’re paper people.” – Grant Morrison
