Jeff Bennett in later appearances) - A gun for hire with a big red beard and sunglasses who works for Napoleon Brie. Plutarkians – The Plutarkians are a race of fish-like aliens that either plan to obtain Earth's resources or conquer Earth. Each of them is named after a cheese. Besides Limburger and Brie, the Plutarkians consist of: Lord Camembert (voiced by Jeff Bennett) – Limburger's higher-up. Limburger finds disgusting especially when he makes him do the embarrassing Plutarkian greeting. In some other cases, he will appear with the entire Plutarkian council with Limburger in a panic over what task is current. He often appears on the vidcom or in person to Limburger and berates him for his failure, often at a loud yelling voice. As High Chairman of Plutark, Camembert holds highest power of the planet for four-year term at once. Mudfish Murdock (voiced by Jeff Bennett) – A Plutarkian trucker who was hired by Limburger to kill the Biker Mice while he attempted to drain Lake Michigan and deliver it to Plutark. Provolone (voiced by Jeff Bennett) – A Plutarkian lawyer. Dominic T. Stilton (voiced by Malcolm McDowell) - A Plutarkian who was Limburger and Karbunkle's superior on Mars prior to the events of the series. Stilton hates Limburger for his scheming and repeated attempts to usurp him. Unlike other Plutarkians, Stilton is a neat freak who constantly carries around handkerchiefs to wipe dirt and grime off of himself and anything he touches. Stilton's plans to destroy the Martian resistance were thwarted by the Biker Mice, and Limburger took advantage of the situation to become an equally-ranked Plutarkian officer, effectively not having to take orders from Stilton anymore. Gerald Guyere (voiced by Jim Cummings) - A Plutarkian operating in New Orleans. Jack Monteray (voiced by Jeff Bennett) - A Plutarkian operating in Las Vegas. He is often nicknamed "One-Eyed Jack". Gutama Gouda (voiced by Jim Cummings) - A Plutarkian operating in Los Angeles. Romana Parmesana (voiced by Tori Spelling in normal form, Jennie Garth as Angel Revson) - A Plutarkian operating in Cleveland. She used her disguise of Angel Revson to manipulate Jack McCyber in her plot to usurp Lawrence Limburger and Napoleon Brie. Pit Boss (voiced by Stu Rosen) – The Pit Boss is the burly ruler of the Pits outside of town. The Pit Boss has an electric whip that he uses to keep his slaves
