Buck's notable antagonists have included the aforementioned X-Tel Corporation, the human collective mind PSmIth (read as "Smithe", referencing the "psi" shortening of "psychic"), the high-grade thief and assassin named Der Rock the Destroyer and the notorious space pirate known as the Pistol Packin' Polaris Packrat (a sentient who has the dubious honor of being the only creature Buck will deal with for free; Al suspects that there's someone out there paying Buck to breathe) with his two talking laser pistols, Smith and Wesson, who have some history with "Junior" and lament that he "isn't speaking to them."
