In Chapter 21 of Rodman Philbrick's teen novel, Freak the Mighty, Max's grandfather explains to the boy that Killer Kane was " 'an accident of nature.' " Grandfather Grim tells Max that all he got from his father was " 'your looks and your size.' " Max's positive qualities--particularly his good heartedness--came from his mother, who was murdered at the hands of Max's father, Killer Kane. In Chapter One, Max overhears his grandparents whispering about his father--how "Maxwell was getting to look like Him"; how Max "is like him"; and how Grim and Gram need to "watch out, you never know what he might do while we're sleeping." Perhaps most importantly, Grim warns Max to stay in the house while his father is on the loose.
