Fat Cat is a fictional character and the overall main antagonist of Chip 'n Dale Rescue Rangers along with the secondary antagonist of the show's five-part episode pilot To the Rescue. He is a felonious gray tabby cat, relentless criminal mastermind, the self-proclaimed ruler of the animal underworld, and the pet of crime boss Aldrin Klordane, until his incarceration. When not in the company of his owner and other humans, he wears a purple business coat over a blue vest, a black dress shirt, and a red necktie among animals. After Klordane was arrested, Fat Cat began operating on his own as an independent agent and crime boss of the animal underworld who has made numerous engagements in various schemes to increase his own wealth and power. He is the Rescue Rangers' most reoccurring archnemesis, whom he hates more than anything in the world (besides dogs) for meddling in his affairs.
