The wolf is an ominous creature, dangerous and deadly enough that everyone seems to fear him except, of course, Peter. His first instinct upon seeing Peter is, of course, to attack relentlessly, and he refuses to give up his prey even when it is high in a tree out of his reach. The wolf is a huge predator with mangy gray fur, big yellow eyes, a vastly exaggerated maw and fangs, large paws complete with enormous claws, and a scraggly triangular build with a larger upper body than lower, his body becoming much slenderer towards his waist and hindquarters.
