Professor Ratigan

Professor Ratigan is a prolific criminal mastermind, expert scenery-chewer and archenemy of the detective Basil of Baker Street. He has the inventor Hiram Flaversham kidnapped to aid in Ratigan's latest plot to seize control of the British monarchy with the use of a robotic replica of the Queen. He despises being called a "rat", and feeds anyone who upsets him to his morbidly obese cat Felicia.
