If everyone found the prospect of being punched in the face pleasant, that would explain how superhero dimensions get formed.
Canon!
…
Non-canon. I got a bit excited there, imaginary readers.
I guess today was an exposition day. Tomorrow possibly won’t be! Let’s find out together. Tomorrow.
So what IS the canon explanation?
Probably something about infinite possibilities over infinite dimensions. I just don’t want all the characters to be excited about being punched. That’d be pretty weird.
Has a character ever gotten punched in one of your comics before?
Oh, sure. It’s not as common as getting shot by lightning or hit with a tadpole, but it happens.
