Mondo is a big game hunter with an unconventional choice of target. He hunts superheroes with the goal of stealing their masks and exposing their identities to the world, thereby shaming them into retirement. For his actions, he is known as the Mad Mask Misappropriator and feared by many a superhero. At the height of his career, he owned 982 superhero masks, Darkwing Duck's included. While he does not possess any super powers, he is smart, knows how to set traps, is an expert climber, and uses the element of surprise, while his own escape is covered by boots with extendable springs.
