Yes he can..but its rare
He would have to exist first!
The devil can be or do anything you imagine him to, since he is a figment of imagination.
It would make sense to me that the devil is a female, as for children they may have been switched at the hospital and now reside in my house.
The devil has all kinds of babies. You ca actually see the devil giving birth in gumdrop forest next to the chocolate waterfall when the sun is just right. Be careful of the elves and goblins when you get there.
Stop being silly people. If and that a big if. The devil could have a kid he would of and the world would be never ending pain
