Agent Double 0-0 is a British spy working for the British Spy Union who is assigned to help Perry the Platypus defeat Dr. Doofenshmirtz. He is a very skilled spy, but seems to make things more difficult than they need to be, like spies do in the movies. He finds it unusual that he's being made to work with a platypus and is taken aback by the lack of details that Major Monogram gives them to find Doofenshmirtz.
