Bosco is smart, loud, and completely paranoid. This is proven with how his business style appears to be based around overcharging for any item so he can afford his elaborate high-tech, homemade security systems, as well as selling his personal brand of "BoscoTech equipment", which are generally rudimentary at best, but cost extraordinary amounts of money. Despite his paranoia and sass, he'll help out Sam and Max whenever they need him, if only because their goals can sometimes meet his ends.
