Theme: throughout the entire book
I think one of the theme's for the story "Freak the Mighty" is your appearance. For example, when Max’s Grandmother tells him, “You can’t judge a book by its cover.” I think this is a good piece of evidence for this theme, because it’s true you can’t judge a book by its cover. Like when everyone thinks that Max is going to be exactly like his dad just because he looks like him, but Max doesn't like that one bit. In all, this is what I think one of the theme's is for this story.
