While not much has been fully explored about the Wolf, since he is meant as a metaphor of Jack, it is safe to assume he has a similar personality as the two are both solitary warriors, traveling alone and fighting beasts that approach them while moving forward.
He is strong and brave, as evidenced when he fights against the three larger beasts despite the clear disadvantage in strength and numbers. He seems prideful and unyielding in a fight.
Despite this, he does not seem to be a particularly violent creature, as he does not attack Jack upon meeting him. He still retains an aggressive personality and a short temper, as he became angry when Jack splashed him with water to help with his wound. In addition, he seems intelligent as it recognizes Jack as a fellow warrior and appears compassionate and friendly as he helps take care of him by bringing him food, licking his wounds and sleeping near Jack to keep him from freezing.
