The first thing that came to my mind after seeing this prompt was "mama bear" with a smile. Of course the name papa bear is just a fiction, it has a figurative meaning. So there are bears but there are no papa bear, it is not literal.
Papa bear can be used to describe someone who is at a place of authority, someone who will make you do what he wants. It can also mean a nice person who is full of compassion and kindness depending on the context used. The later is especially for kids.
