Codename: Agent 27B, known on Earth as Mister Kat, is an evil, presumably mad scientist from catnip who has a tremendous similarity to a typical Sphynx cat. His claws appear to be made of some type of stronger-than-steel metal. Despite being a rocket scientist with an obviously tremendous intelligence quotient, he is not particularly creative when it comes to plans on defeating his rival, Cooper "Coop" Burtonburger.
