Baron Von Rottweiler is a recurring villain on Dog City. A stereotypical German villain complete with monocle, tailored suits, and sharp accent, Rottweiler was originally used as a secondary villain, in comparison to Bugsy Vile. His earliest appearances were limited to threatening Ace Hart (and being foiled by him) in the brief scenes animated by Eliot Shag as a preamble to the story proper. In his premiere appearance, "The Big Squeak," the baron and his ever-present silent lackey, Leon, have their lair at the Rottweiler Explosives Incorporated factory. Not coincidentally, Rottweiler is rarely seen without dynamite or bombs or some form of incendiary device.
