Perry is the docile pet platypus of the blended Flynn-Fletcher family, who adopted him because his unfocused gaze made it seem as if he were looking at both Phineas and Ferb at the same time, as shown in the 2011 movie, Phineas and Ferb the Movie: Across the 2nd Dimension. Unbeknownst to them, Perry lives a double life as a crime-fighting spy working for the "Organization Without a Cool Acronym"/The OWCA, going by the codename "Agent P. " He reports to his superior, Major Monogram, via telecast in his large, high-tech, underground hideout. Every day, he engages in battles with the evil scientist Dr. Heinz Doofenshmirtz, who tries using inventions to take over the tri-state area. Perry is always able to foil Doofenshmirtz's plans and in doing so accidentally leads to the destruction of whatever form of contraption his owners, Phineas Flynn and Ferb Fletcher, are building in order to make summer better. Phineas and Ferb are aware that something happens to get rid of their scheme for the day, but do not know that Perry is the cause behind it and are largely dismissive of it. Their sister, Candace, also does not know that Perry is behind the destruction and is driven to near insanity trying to figure it out. Throughout the series, Perry is aware of Phineas and Ferb's inventions, but is largely uninterested in them, save whenever he notices that their latest invention may help him thwart Doofenshmirtz.
