“Tire” Jack is the leader of the Mechanic Squad, a group of brutes that run a garage in the wastelands. They aren’t very good but they are the only people around that have the equipment to do repairs. They are allies of the Lesbian Biker Girls.
Jack is the smartest of the group and knows how to change the oil in a car. He fights with two tire irons, one of which is sharpened to a point. He will avoid combat when it’s unnecessary, unlike the rest of the group who look for any excuse to fight.
