A member of the Red Dozer bandits, led by her father, Doug. He was ambushed by a rival gang: the Skullkers, who also stole her mother’s Red Diamond. Taking up the Drill Dozer (which she actually used instead of a baby carriage growing up), Jill sets out to defeat the Skullkers and recover the Diamond. Using the mech, she can do all kinds of things: turn screws, fight enemies, and even destroy the environment!
