 Despite his scheming and reckless personality, he is a devoted foe of the Adversary and a capable combatant in his own right, due to his years of experience fighting giants.He can also have true feelings for others (he asks Beast about Snow White and her cubs, he mourns his wife's death and he considered putting his own safety at risk to protect Gary when the Librarians had captured them and were having a car accident).In the series, Jack creates a film trilogy of his adventures to increase his popularity in the Mundy world making him nigh-immortal (a theory that is still strongly disputed to this day, even by Frau Totenkinder).
