Leo is a middle-aged mechanic with a gruff demeanor and a passion for his work, particularly as Django's mechanic. He's easily irritated when Jo pushes Django too hard or when Meg disrupts him while he is working. Though generally responsible, Leo struggles to suppress his childish impulses—such as when he recklessly drives a go-kart off the raceway during a trip to Fortune Island's Artificial Beach resort. Despite his primary role as the team's mechanic, Leo is no stranger to combat, having wielded a pair of sub-machine guns in several dangerous situations.
