King ratigan
"Oh, I love it when I'm Nasty."-Ratigan

Ratigan (voiced by the late Vincent Price) is the main antagonist of The Great Mouse Detective. He's a evil sewer rat who is a powerful criminal. Basil himself called Ratigan, "The Napoleon of Crime", seeing as how he's known The World's Greatest Criminal Mind.

Personality-wise, Ratigan is very charismatic, calm and calculating, but can easily be sent into a violent rage at the mention of his enemy Basil or the incompetence of his minions. He has a very dark, malicious sense of humor and a inflated ego.

Even though he IS one, Ratigan hates being called a rat.
