The series is set in Little Tokyo, a mechanical city which fuses feudal Japanese culture with contemporary culture, and is populated by cybernetic anthropomorphic animals. The city is nominally led by Emperor Fred, a doddering eccentric. The city's actual leadership lies in the hands of the city council and the emperor's daughter, Princess Violet. The council is headed by ambitious Prime Minister Seymour "The Big" Cheese, a rat who constantly plots to overthrow the Emperor. Big Cheese is aided by his inept minions: trusted adviser Jerry Atric and Bad Bird, the leader of an army of ninja crows.
Unknown to the prime minister, council member and palace guard commander "Big" Al Dente has learned of his designs on leadership, but is unable to prosecute him for treason because of the plausible deniability he maintains. Instead, Al Dente enlists the services of Speedy Cerviche, Polly Esther, and Guido Anchovy, three cyborg cat samurai who work in the city's pizzeria, along with their operator, Francine.[8] Known collectively as the Samurai Pizza Cats, the three are assigned to stop Big Cheese and his evil henchmen's plans to take over Little Tokyo.
