The Greatest Spy in the World is the Spy Rats' master, from the Chip 'n Dale Rescue Rangers episode "Double 'O Chipmunk".


The "greatest spy in the world" is a tall, slender man who wears a white spy coat with a black shirt under it.


The Spy captures another spy and steals his clothes. He puts on white hair and a white mustache to disguise himself. He makes the spy rats take a microchip to their home.

The spy later goes to the lab and sees the spy rats running away from a machine the Rescue Rangers are using. He escapes with his rodent sidekicks. After the Rescue Rangers defeat him, the spy and his rats get arrested.
