Perry the Platypus, also known as Agent P or simply Perry, is an anthropomorphic platypus from the animated television series Phineas and Ferb. Perry is voiced by Dee Bradley Baker and created by the series' co-founders, Dan Povenmire and Jeff "Swampy" Marsh. He first appeared along with the majority of the main cast in the pilot episode "Rollercoaster." Perry is featured as the star of the B-plot for every episode of the series, alongside his nemesis Dr. Heinz Doofenshmirtz.
Perry is the pet platypus of the Flynn-Fletcher family, and is perceived as mindless and domesticated. In secret, however, he lives a double life as a member of an all-animal espionage organization referred to as the O.W.C.A.
